4.1 Million Shares

Nuveen California AMT-Free Quality Municipal Income Fund

Common Shares

Nuveen California AMT-Free Quality Municipal Income Fund (the “Fund”) is a diversified, closed-end management investment company. The Fund’s investment objectives are (i) to provide current income exempt from regular federal income tax, the federal alternative minimum tax applicable to individuals and California income tax and (ii) to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal securities that Nuveen Fund Advisors, LLC (“NFALLC”), the Fund’s investment adviser, and/or Nuveen Asset Management, LLC (“Nuveen Asset Management”), the Fund’s sub-adviser, believes are underrated or undervalued or that represent municipal market sectors that are undervalued. The Fund cannot assure you that it will achieve its investment objectives.

Investing in the Fund’s common shares (“Common Shares”) involves certain risks that are described in the “Risk Factors” section of this Prospectus (the “Prospectus”), including the specific risks relating to the Fund’s use of leverage.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of these securities or determined if this Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

You should read this Prospectus, which contains important information about the Fund, before deciding whether to invest and retain it for future reference. A Statement of Additional Information (the “SAI”), dated [ ], 2018, containing additional information about the Fund, has been filed with the SEC and is incorporated by reference in its entirety into this Prospectus. You may request a free copy of the SAI, the table of contents of which is on the last page of this Prospectus, annual and semi-annual reports to shareholders and other information about the Fund, and make shareholder inquiries by calling (800) 257-8787, by writing to the Fund or from the Fund’s website (http://www.nuveen.com). The information contained in, or that can be accessed through, the Fund’s website is not part of this Prospectus. You also may obtain a copy of the SAI (and other information regarding the Fund) from the SEC’s web site (http://www.sec.gov).

The Fund’s Common Shares do not represent a deposit or obligation of, and are not guaranteed or endorsed by, any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other governmental agency.

Portfolio Contents. As a fundamental policy, under normal circumstances, the Fund will invest at least 80% of its net assets (total assets less liabilities), plus the amount of any borrowings for investment purposes (“Assets”), in municipal securities and other related investments the income from which is exempt from federal and California income taxes.

As a non-fundamental policy that may be changed by the Fund’s Board of Trustees without shareholder notice, under normal circumstances, the Fund will invest 100% of its Managed Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase. As a non-fundamental policy subject to change by the Fund’s Board of

Trustees upon 60 days’ notice to the shareholders, under normal circumstances, the Fund will invest 80% of its Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase.

As a non-fundamental policy subject to change by the Fund’s Board of Trustees upon 60 days’ notice to the shareholders, under normal circumstances, the Fund will invest at least 80% of its Managed Assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one nationally recognized statistical rating organization or are unrated but judged to be of comparable quality by NFALLC and/or Nuveen Asset Management. The Fund may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by Nuveen Asset Management. No more than 10% of the Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by NFALLC and/or Nuveen Asset Management. The Fund may invest in distressed securities. The Fund may not invest in the securities of an issuer which, at the time of investment, is in default on its obligations to pay principal or interest thereon when due or that is involved in a bankruptcy proceeding (i.e., rated below C-, at the time of investment); provided, however, that Nuveen Asset Management may determine that it is in the best interest of shareholders in pursuing a workout arrangement with issuers of defaulted securities to make loans to the defaulted issuer or another party, or purchase a debt, equity or other interest from the defaulted issuer or another party, or take other related or similar steps involving the investment of additional monies, but only if that issuer’s securities are already held by the Fund. Municipal securities of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as junk bonds.

The Fund may invest up to 15% of its Managed Assets in inverse floating rate securities. Currently, the Fund employs leverage through its investments in inverse floating rate securities, its outstanding Variable Rate Demand Preferred Shares, and its outstanding MuniFund Preferred Shares.

Adviser and Sub-Adviser. NFALLC, the Fund’s investment adviser, is responsible for determining the Fund’s overall investment strategies and their implementation. Nuveen Asset Management is the Fund’s investment sub-adviser and oversees the day-to-day investment operations of the Fund. The Fund pays NFALLC a management fee (which in turn pays Nuveen Asset Management a portion of its fee) based on a percentage of Managed Assets, which includes the proceeds realized from the Fund’s use of leverage. As a result, NFALLC may have a conflict of interest in determining whether to use or increase leverage.

The minimum price on any day at which Common Shares may be sold will not be less than the current net asset value per share plus the per share amount of the commission to be paid to the Fund’s distributor, Nuveen Securities, LLC (“Nuveen Securities”). The Fund and Nuveen Securities will suspend the sale of Common Shares if the per share price of the shares is less than the minimum price. The Fund currently intends to distribute the shares offered pursuant to this Prospectus primarily through at-the-market transactions, although from time to time it may also distribute shares through an underwriting syndicate or a privately negotiated transaction. To the extent shares are distributed other than through at-the-market transactions, the Fund will file a supplement to this Prospectus describing such transactions. For information on how Common Shares may be sold, see the “Plan of Distribution” section of this Prospectus.

Common Shares are listed on the New York Stock Exchange (the “NYSE”). The trading or “ticker” symbol of the Fund is “NKX.” The Fund’s closing price on the NYSE April 26, 2018 was $13.32.

The date of this Prospectus is [ ], 2018

PROSPECTUS SUMMARY

This is only a summary. You should review the more detailed information contained elsewhere in this Prospectus and in the Statement of Additional Information (the “SAI”).

The Fund

Nuveen California AMT-Free Quality Municipal Income Fund (the “Fund”) is a diversified, closed-end investment management company. See “The Fund.” The Fund’s common shares, $0.01 par value (“Common Shares”), are traded on the New York Stock Exchange (the “NYSE”) under the symbol “NKX.” See “Description of Common Shares.” As of March 31, 2018, the Fund had 47,750,334 Common Shares outstanding, 2,922 of Variable Rate Demand Preferred Shares (referred to herein as “VRDP Shares”), 1,404 of MuniFund Preferred Shares (referred to herein as “MFP Shares”), and net assets (total assets less liabilities) applicable to Common Shares of $731,018,709.

Investment Objectives and Policies

The Fund’s investment objectives are (i) to provide current income exempt from regular federal income tax, the federal alternative minimum tax applicable to individuals and California income tax and (ii) to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal securities that the Fund’s investment adviser, Nuveen Fund Advisors, LLC (“NFALLC”), and/or sub-adviser, Nuveen Asset Management, LLC (“Nuveen Asset Management”), believes are underrated or undervalued or that represent municipal market sectors that are undervalued.

As a fundamental policy, under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes (“Assets”), in municipal securities and other related investments the income from which is exempt from federal and California income taxes.

“Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage, and derivatives will be valued at their market value.

As a non-fundamental policy which may be changed by the Fund’s Board of Trustees (the “Board”) without shareholder notice, under normal market circumstances, the Fund will invest 100% of its Managed Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase. As a non-fundamental policy subject to change by the Fund’s Board upon 60 days’ notice to the shareholders, under normal circumstances, the Fund will invest 80% of its Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase.

grades (Baa or BBB or better) by at least one nationally recognized statistical rating organization (“NRSROs”) or are unrated but judged to be of comparable quality by NFALLC and/or Nuveen Asset Management.

Additionally, as a non-fundamental policy, the Fund:

•

may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by NFALLC and/or Nuveen Asset Management.

•

may invest up to 10% of its Fund’s Managed Assets in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by NFALLC and/or Nuveen Asset Management.

•

may invest up to 10% of its total assets in securities of other open- or closed-end investment companies (including exchange-traded funds (often referred to as “ETFs”)) that invest primarily in municipal securities of the types in which the Fund may invest directly.

•

may invest in distressed securities but may not invest in the securities of an issuer which, at the time of investment, is in default on its obligations to pay principal or interest thereon when due or that is involved in a bankruptcy proceeding (i.e., rated below C-, at the time of investment); provided, however, that Nuveen Asset Management may determine that it is in the best interest of shareholders in pursuing a workout arrangement with issuers of defaulted securities to make loans to the defaulted issuer or another party, or purchase a debt, equity or other interest from the defaulted issuer or another party, or take other related or similar steps involving the investment of additional monies, but only if that issuer’s securities are already held by the Fund.

•

may invest up to 15% of its Managed Assets in inverse floating rate securities.

The Fund may invest in various municipal securities, including municipal bonds and notes, other municipal securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular federal income tax, the federal alternative minimum tax applicable to individuals and California income tax. Municipal securities are often issued by state and local governmental entities to finance or refinance public projects, such as roads, schools, and water supply systems. Municipal securities also may be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility and pollution control projects. Municipal securities may be issued on a long-term basis to provide long-term financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments, and mortgage payments. Municipal securities also may be issued to finance

projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. The Fund may purchase municipal securities in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms that include fixed coupon, variable rate, zero coupon, capital appreciation bonds, tender option bonds, and inverse floating rate securities. Such municipal securities also may be acquired through investments in pooled vehicles, partnerships, or other investment companies. See “The Fund’s Investments—Municipal Securities” for additional information on the types of municipal securities in which the Fund may invest.

The Fund will generally invest in municipal securities with intermediate or long-term maturities. Generally, the Fund is expected to have an average effective maturity of 15 to 30 years. The average effective maturity of securities held by the Fund may be shortened or lengthened, depending on market conditions. As of March 31, 2018, the effective maturity of the Fund’s portfolio was 22.48 years.

A security is considered investment grade quality if it is rated within the four highest grades by at least one of the NRSROs that rate such security, or if it is unrated but judged to be of comparable quality by Nuveen Asset Management. Municipal securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as junk bonds.

As of March 31, 2018, approximately 87% of the Fund’s Managed Assets were invested in municipal securities rated investment grade by an NRSRO (including S&P Global Ratings (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”) and Fitch Ratings, Inc. (“Fitch”)). The relative percentages of the value of the investments attributable to investment grade municipal securities and to below investment grade municipal securities could change over time as a result of rebalancing the Fund’s assets by Nuveen Asset Management, market value fluctuations, issuance of additional shares and other events.

The Fund also may invest in certain derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts, or other derivative instruments. Nuveen Asset Management may use derivative instruments to seek to enhance return, to hedge some of the risk of the Fund’s investments in municipal securities or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income. As of February 28, 2018, the Fund was not invested in derivatives. See “The Fund’s Investments—Municipal Securities—Derivatives.”

For purposes of determining compliance with the Fund’s investment policies, for purposes of calculating Managed Assets, the Fund will value eligible derivatives at market value or fair value instead of notional value.

During temporary defensive periods or in order to help keep the Fund’s assets fully invested, including during the period when the net proceeds of the offering of Common Shares are first being invested, the Fund may deviate from its investment policies and objectives. During such periods the Fund may invest up to 100% of its Managed Assets in short-term

investments. There can be no assurance that such strategies will be successful. For a more complete discussion of the Fund’s portfolio composition, see “The Fund’s Investments” and “Risk Factors.”

There can be no assurance that the Fund will achieve its investment objectives. See “The Fund’s Investments—Investment Objectives and Policies.”

Investment Adviser

Nuveen Fund Advisors, LLC, (“NFALLC”) the Fund’s investment adviser, is responsible for overseeing the Fund’s overall investment strategy and implementation. NFALLC offers advisory and investment management services to a broad range of investment company clients. NFALLC has overall responsibility for management of the Fund, oversees the management of the Fund’s portfolio, manages the Fund’s business affairs and provides certain clerical, bookkeeping and other administrative services. NFALLC is located at 333 West Wacker Drive, Chicago, Illinois 60606. NFALLC is a subsidiary of Nuveen, LLC (“Nuveen”), the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). TIAA is a life insurance company founded in 1918 by the Carnegie Foundation for the Advancement of Teaching and is the companion organization of College Retirement Equities Fund. As of March 31, 2018, Nuveen managed approximately $967 billion in assets, of which approximately $139 billion was managed by NFALLC.

Sub-Adviser

Nuveen Asset Management, LLC (“Nuveen Asset Management”) serves as the Fund’s sub-adviser and is a wholly-owned subsidiary of NFALLC. Nuveen Asset Management is a registered investment adviser. Nuveen Asset Management oversees the day-to-day investment operations of the Fund.

Nuveen Securities, LLC (“Nuveen Securities”), a registered broker-dealer affiliate of NFALLC and Nuveen Asset Management, is involved in the offering of the Fund’s Common Shares. See “Plan of Distribution- Distribution Through At-The-Market Transactions.”

Use of Leverage

The Fund uses leverage to pursue its investment objective. The Fund may use leverage to the extent permitted by the 1940 Act. The Fund may source leverage through a number of methods including the issuance of preferred shares of beneficial interest (“Preferred Shares”), investments in inverse floating rate securities, entering into reverse repurchase agreements and borrowings (subject to certain investment restrictions). See “The Fund’s Investments—Municipal Securities—Inverse Floating Rate Securities”; “Risk Factors—Inverse Floating Rate Securities Risk”; “Risk Factors–Reverse Repurchase Agreements”; and “Investment Restrictions” in the Statement of Additional Information. The Fund may invest up to 15% of its Managed Assets in inverse floating rate securities. The Fund may also use certain derivatives that have the economic effect of leverage by creating additional investment exposure.

The Fund currently employs leverage primarily through its outstanding VRDP Shares and MFP Shares, both Preferred Shares. For the period March 1, 2018, through April 23, 2018, the average liquidation value of the VRDP Shares outstanding was $292,200,000 and the average annual dividend rate on the VRDP Shares was 1.48%. For the period March 1, 2018 through April 23, 2018 the average liquidation value of the MFP Shares outstanding was $140,400,000 and the average annual dividend rate

on the MFP Shares was 1.72%. As of April 23, 2018, the Fund’s leverage through Preferred Shares and through its investments in inverse floating rate securities was approximately 40% of its Managed Assets.

The Fund may also borrow for temporary purposes permitted by the 1940 Act. The Fund, along with certain other funds managed by NFALLC (the “Participating Funds”), are party to a committed unsecured credit facility (the “Facility”) provided by a group of lenders, under which Participating Funds may borrow for temporary purposes only. Outstanding balances drawn by the Fund, or a Participating Fund, will bear interest at a variable rate and is the liability of such Fund. The Facility is not intended for sustained levered investment purposes. A large portion of the Facility’s capacity (and corresponding annual costs, excluding interest cost) is currently allocated by NFALLC to a small number or Participating Funds, which does not include the Fund. The Facility has a 364-day term and will expire in July 2018 unless extended or renewed.

The Fund may reduce or increase leverage based upon changes in market conditions and anticipates that its leverage ratio will vary from time to time based upon variations in the value of the Fund’s holdings. So long as the net rate of income received on the Fund’s investments exceeds the then current expense on any leverage, leverage will generate more net income than if the Fund had not used leverage. If so, the excess net income will be available to pay higher distributions to Common Shareholders. However, if the rate of net income received from the Fund’s portfolio investments is less than the then current expense on outstanding leverage, the Fund may be required to utilize other Fund assets to make expense payments on outstanding leverage, which may result in a decline in Common Share NAV and reduced net investment income available for distribution to Common Shareholders.

The Fund pays a management fee to NFALLC (which in turn pays a portion of such fee to Nuveen Asset Management) based on a percentage of Managed Assets. Managed Assets include the proceeds realized and managed from the Fund’s use of most types of leverage (excluding the leverage exposure attributable to the use of futures, swaps and similar derivatives). Because Managed Assets include the Fund’s net assets as well as assets that are attributable to the Fund’s investment of the proceeds of its leverage (including instruments like inverse floating rate securities and reverse repurchase agreements), it is anticipated that the Fund’s Managed Assets will be greater than its net assets. NFALLC will be responsible for using leverage to pursue the Fund’s investment objective. NFALLC will base its decision regarding whether and how much leverage to use for the Fund, and the terms of that leverage, on its assessment of whether such use of leverage is in the best interests of the Fund. However, a decision to employ or increase leverage will have the effect, all other things being equal, of increasing Managed Assets, and in turn NFALLC’s and Nuveen Asset Management’s management fees. Thus, NFALLC may have a conflict of interest in determining whether to use or increase leverage. NFALLC will seek to manage that potential conflict by using leverage only when it determines that it would be in the best interests of the Fund and its Common Shareholders, and by periodically reviewing with the Board of

Trustees the Fund’s performance, the Fund’s degree of overall use of leverage and the impact of the use of leverage on that performance.

The use of leverage creates additional risks for Common Shareholders, including increased variability of the Fund’s NAV, net income and distributions in relation to market changes. See “Use of Leverage” and “Risk Factors—Leverage Risk.” There is no assurance that the Fund will use leverage or that the Fund’s use of leverage will work as planned or achieve its goals.

Offering Methods

The Fund may offer shares using one or more of the following methods: (i) at-the-market transactions conducted through one or more broker-dealers that have entered into a selected dealer agreement with Nuveen Securities, one of the Fund’s underwriters; (ii) through an underwriting syndicate; and (iii) through privately negotiated transactions between the Fund and specific investors. See “Plan of Distribution.”

Distribution Through At-the-Market Transactions. The Fund, from time to time, may issue and sell its Common Shares through Nuveen Securities, to certain broker-dealers that have entered into selected dealer agreements with Nuveen Securities. Currently, Nuveen Securities has entered into a dealer agreement with UBS Securities, LLC (“UBS”) pursuant to which UBS will be acting as Nuveen Securities’ sub-placement agent with respect to at-the-market offerings of Common Shares. Common Shares will only be sold on such days as shall be agreed to by the Fund, Nuveen Securities and UBS. Common Shares will be sold at prevailing market prices through the National Market System, subject to a minimum price to be established each day by Nuveen Securities. The minimum price on any day will not be less than the current net asset value (“NAV”) per share plus the per share amount of the commission to be paid to Nuveen Securities. The Fund and Nuveen Securities will suspend the sale of Common Shares if the per share price of the shares is less than the minimum price.

The Fund will compensate Nuveen Securities with respect to sales of the Common Shares at a commission rate of up to 1.0% of the gross proceeds of the sale of Common Shares. Nuveen Securities will compensate sub-placement agents or other broker-dealers participating in the offering at a rate of up to 0.8% of the gross sales proceeds of the sale of Common Shares sold by that sub-placement agent or other broker-dealer.

Settlements of Common Share sales will occur on the third business day following the date of sale. In connection with the sale of the Common Shares on behalf of the Fund, Nuveen Securities may be deemed to be an underwriter within the meaning of the Securities Act of 1933, as amended (the “1933 Act”), and the compensation of Nuveen Securities may be deemed to be underwriting commissions or discounts. Unless otherwise indicated in a further Prospectus supplement, Nuveen Securities will act as underwriter on a reasonable efforts basis.

The offering of Common Shares pursuant to the Distribution Agreement (defined under “Plan of Distribution—Distribution Through At-The-Market Transactions”) will terminate upon the earlier of (i) the sale of all Common Shares subject thereto or (ii) termination of the Distribution Agreement. The Fund and Nuveen Securities each have the right to terminate the Distribution Agreement in its discretion at any time. See “Plan of

Distribution—Distribution Through At-The-Market Transactions.” The Fund currently intends to distribute the shares offered pursuant to this Prospectus primarily through at-the-market transactions, although from time to time it may also distribute shares through an underwriting syndicate or a privately negotiated transaction. To the extent shares are distributed other than through at-the-market transactions, the Fund will file a supplement to this Prospectus describing such transactions.

UBS, its affiliates and their respective employees hold or may hold in the future, directly or indirectly, investment interests in Nuveen Investments and its funds. The interests held by employees of UBS or its affiliates are not attributable to, and no investment discretion is held by, UBS or its affiliates.

The Fund’s closing price on the NYSE on April 26, 2018 was $13.32.

Distribution Through Underwriting Syndicates. The Fund from time to time may issue additional Common Shares through a syndicated secondary offering. In order to limit the impact on the market price of the Fund’s Common Shares, underwriters will market and price the offering on an expedited basis (e.g., overnight or similarly abbreviated offering period). The Fund will launch a syndicated offering on a day, and upon terms, mutually agreed upon between the Fund, Nuveen Securities and the underwriting syndicate.

The Fund will offer its shares at a price equal to a specified discount of up to 5% from the closing market price of the Fund’s Common Shares on the day prior to the offering date. The applicable discount will be negotiated by the Fund and Nuveen Securities in consultation with the underwriting syndicate on a transaction-by-transaction basis. The Fund will compensate the underwriting syndicate out of the proceeds of the offering based upon a sales load of up to 4% of the gross proceeds of the sale of Common Shares. The minimum net proceeds per share to the Fund will not be less than the greater of (i) the Fund’s latest NAV per share of Common Shares or (ii) 91% of the closing market price of the Fund’s Common Shares on the day prior to the offering date. See “Plan of Distribution—Distribution Through Underwriting Syndicates.”

Distribution Through Privately Negotiated Transactions. The Fund, through Nuveen Securities, from time to time may sell directly to, and solicit offers from, institutional and other sophisticated investors, who may be deemed to be underwriters as defined in the 1933 Act for any resale of Common Shares. No sales commission or other compensation will be paid to Nuveen Securities or any other FINRA member in connection with such transactions.

The terms of such privately negotiated transactions will be subject to the discretion of the management of the Fund. In determining whether to sell Common Shares through a privately negotiated transaction, the Fund will consider relevant factors including, but not limited to, the attractiveness of obtaining additional funds through the sale of Common Shares, the purchase price to apply to any such sale of Common Shares and the investor seeking to purchase the Common Shares.

Common Shares issued by the Fund through privately negotiated transactions will be issued at a price equal to the greater of (i) the NAV per Common Share or (ii) at a discount ranging from 0% to 5% of the average

daily closing market price of the Fund’s Common Shares at the close of business on the two business days preceding the date upon which Common Shares are sold pursuant to the privately negotiated transaction. The applicable discount will be determined by the Fund on a transaction-by-transaction basis. See “Plan of Distribution—Distribution Through Privately Negotiated Transactions.”

The principal business address of Nuveen Securities is 333 West Wacker Drive, Suite 3300, Chicago, Illinois 60606.

Special Risk Considerations

Investment in the Fund involves special risk considerations, which are summarized below. The Fund is designed as a long-term investment vehicle and not as a trading vehicle. The Fund is not intended to be a complete investment program. See “Risk Factors” for a more complete discussion of the special risk considerations of an investment in the Fund.

Investment and Market Risk. An investment in the Fund’s Common Shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in Common Shares represents an indirect investment in the municipal securities owned by the Fund, substantially all of which are traded on a national securities exchange or in the over-the-counter markets. Your Common Shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions. See “Risk Factors—Investment and Market Risk.”

Market Discount from Net Asset Value. Shares of closed-end investment companies like the Fund have during some periods traded at prices higher than NAV and have during other periods traded at prices lower than NAV. The Fund cannot predict whether Common Shares will trade at, above or below NAV. This characteristic is a risk separate and distinct from the risk that the Fund’s NAV could decrease as a result of investment activities. Investors bear a risk of loss to the extent that the price at which they sell their shares is lower in relation to the Fund’s NAV than at the time of purchase, assuming a stable NAV. Proceeds from the sale of Common Shares in this offering will be reduced by shareholder transaction costs (if applicable, which vary depending on the offering method used). The NAV per Common Share will be reduced by costs associated with any future issuances of Common Shares or Preferred Shares. Depending on the premium of Common Shares at the time of any offering of Common Shares hereunder, the Fund’s NAV may be reduced by an amount up to the offering costs (estimated to be an additional 0.31% of the offering price assuming a Common Share offering price of $13.32 (the Fund’s closing price on the NYSE on April 26, 2018)). The Common Shares are designed primarily for long-term investors, and you should not view the Fund as a vehicle for trading purposes. See “Risk Factors—Market Discount from Net Asset Value.”

Recent Market Conditions. Since the financial crisis that started in 2008, the U.S. and many foreign economies continue to experience its after-effects, which have resulted, and may continue to result, in certain instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. These events have reduced the willingness and ability of some lenders to

extend credit, and have made it more difficult for some borrowers to obtain financing on attractive terms, if at all. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

In addition, political events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. The U.S. government has recently reduced federal corporate income tax rates, and future legislative, regulatory and policy changes may result in more restrictions on international trade, less stringent prudential regulation of certain players in the financial markets, and significant new investments in infrastructure and national defense. Interest rates have been unusually low in recent years in the U.S. and abroad. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase, whether brought about by U.S. policy makers or by dislocations in world markets. In addition, there is a risk that the prices of goods and services in the U.S. and many foreign economies may decline over time, known as deflation (the opposite of inflation). Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely. To the extent the Fund focuses its investments in a region enduring geopolitical market disruption, it will face higher risks of loss. Thus, investors should closely monitor current market conditions to determine whether the Fund meets their individual financial needs and tolerance for risk.

Legislation and Regulatory Risk. At any time after the date of this Prospectus, legislation or additional regulations may be enacted that could negatively affect the assets of the Fund, securities held by the Fund or the issuers of such securities. Fund shareholders may incur increased costs resulting from such legislation or additional regulation. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Fund or will not impair the ability of the Fund to achieve its investment objectives. The U.S. Securities and Exchange Commission (the “SEC”) proposed rules governing the use of derivatives by registered investment companies, which could affect the nature and extent of derivatives used by the Fund. The proposed rules have not yet been adopted and therefore the full extent of such rules is uncertain at this time. It is possible that such rules, if adopted, could limit the implementation of the Fund’s use of derivatives, which could have an adverse impact on the Fund.

Economic and Political Events Risk. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds or moral obligation bonds). Such developments may adversely affect a specific

industry or local political and economic conditions, and thus may lead to declines in the bonds’ creditworthiness and value.

Credit Risk. Credit risk is the risk that one or more municipal securities in the Fund’s portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. If a municipal security satisfies the rating requirements described above at the time of investment and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. If a downgrade occurs, Nuveen Asset Management will consider what action, including the sale of the security, is in the best interests of the Fund and its shareholders. This means that the Fund may be invested in municipal securities that have become involved in bankruptcy or insolvency proceedings; and may invest in municipal securities that are experiencing financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities).

See “Risk Factors—Credit Risk.”

Below Investment Grade Risk. Municipal securities of below investment grade quality are predominately speculative with respect to the issuer’s capacity to pay interest and repay principal when due, and are susceptible to default or decline in market value due to adverse economic and business developments, and are commonly referred to as junk bonds. Also, to the extent that the rating assigned to a municipal security in the Fund’s portfolio is downgraded by any NRSRO, the market price and liquidity of such security may be adversely affected. The market values for municipal securities of below investment grade quality tend to be volatile, and these securities are less liquid than investment grade municipal securities. For these reasons, an investment in the Fund compared with a portfolio consisting solely of investment grade securities, may experience the following:

•

increased price sensitivity resulting from changing interest rates and/or a deteriorating economic environment;

•

greater risk of loss due to default or declining credit quality;

•

adverse issuer specific events that are more likely to render the issuer unable to make interest and/or principal payments; and

•

the possibility that a negative perception of the below investment grade market develops, resulting in the price and liquidity of below investment grade securities becoming depressed, and this negative perception could last for a significant period of time.

See “Risk Factors—Below Investment Grade Risk.”

Reverse Repurchase Agreement Risk. Reverse repurchase agreements involve the sale of securities held by the Fund with an agreement to repurchase the securities at an agreed-upon price and date, thereby establishing an effective interest rate. The Fund’s use of reverse repurchase agreements, in economic essence, constitute a securitized borrowing by the Fund from the security purchaser. The Fund may enter into reverse repurchase agreements for the purpose of creating a leveraged investment

exposure and, as such, their usage involves essentially the same risks associated with a leveraging strategy generally since the proceeds from these agreements may be invested in additional securities. However, the effective borrowing rate paid by the Fund to the reverse repurchase agreement counterparty will be treated as taxable income, unlike the effective borrowing rate paid by the Fund on Preferred Shares or on inverse floating rate securities, where is generally tax-exempt to the recipient, meaning that the effective borrowing rate paid by the Fund on a reverse repurchase agreement would, all other things being equal, will tend to be higher than those other forms of leverage. Reverse repurchase agreements tend to be short-term in tenor, and there can be no assurances that the purchaser (lender) will commit to extend or “roll” a given agreement upon its agreed-upon repurchase date if such roll is requested by the Fund or an alternative purchaser can be identified on similar terms. Reverse repurchase agreements also involve the risk that the purchaser (lender) fails to return the securities as agreed upon, files for bankruptcy or becomes insolvent. The Fund may be restricted from taking normal portfolio actions during such time, could be subject to loss to the extent that the proceeds of the agreement are less than the value of securities subject to the agreement and may experience adverse tax consequences.

Interest Rate Risk. Generally, when market interest rates rise, bond prices fall, and vice versa. Interest rate risk is the risk that the municipal securities in the Fund’s portfolio will decline in value because of increases in market interest rates. As interest rates decline, issuers of municipal securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of securities, potentially locking in a below-market interest rate and reducing the Fund’s value. Currently, market interest rates are at or near long-term historical lows. In typical market interest rate environments, the prices of longer-term municipal securities generally fluctuate more than prices of shorter-term municipal securities as interest rates change. Because the Fund invests generally in long-term municipal securities, the Common Share NAV and market price per share will fluctuate more in response to changes in market interest rates than if the Fund invested generally in shorter-term municipal securities. In comparison to maturity (which is the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments and call features, in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. For example, the price of a bond with an effective duration of two years will rise (fall) two percent for every one percent decrease (increase) in its yield, and the price of a five-year duration bond will rise (fall) five percent for a one percent decrease

(increase) in its yield. Greater sensitivity to interest rates typically corresponds to higher volatility and higher risk.

Yield curve risk is the risk associated with either a flattening or steepening of the yield curve, which is a result of changing yields among comparable bonds with different maturities. When market interest rates, or yields, increase, the price of a bond will decrease and vice versa. When the yield curve shifts, the price of the bond, which was initially priced based on the initial yield curve, will change in price. If the yield curve flattens, then the yield spread between long- and short-term interest rates narrows, and the price of the bond will change accordingly. If the bond is short-term and the yield decreases, the price of this bond will increase. If the yield curve steepens, this means that the spread between long- and short-term interest rates increases. Therefore, long-term bond prices, like the ones held by the Fund, will decrease relative to short-term bonds. Changes in the yield curve are based on bond risk premiums and expectations of future interest rates. Because the values of lower-rated and comparable unrated debt securities are affected both by credit risk and interest rate risk, the price movements of such lower grade securities in response to changes in interest rates typically have not been highly correlated to the fluctuations of the prices of investment grade quality securities in response to changes in market interest rates. The Fund’s use of leverage, as described herein, will tend to increase Common Share interest rate risk. See “Risk Factors—Interest Rate Risk.”

Municipal Securities Market Risk. The municipal market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the recent market turmoil these firms’ capital was severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal bonds.

Generally, when market interest rates rise, bond prices fall, and vice versa. Interest rate risk is the risk that the municipal securities in the Fund’s portfolio will decline in value because of increases in market interest rates. Currently, market interest rates are at or near historically low levels which may be unsustainable. In typical market interest rate environments, the prices of longer-term municipal securities generally fluctuate more than prices of shorter-term municipal securities as interest rates change. Because the Fund will invest generally in longer-term municipal securities, the Common Share net asset value and market price per share will fluctuate more in response to changes in market interest rates than if the Fund invested generally in shorter-term municipal securities. See “Risk Factors—Municipal Securities Market Risk” and “Risk Factors—Special Risks Related to Certain Municipal Obligations.”

Concentration in California Issuers. The Fund’s policy of investing in municipal securities of issuers located in California makes the Fund more susceptible to the adverse economic, political or regulatory occurrences affecting such issuers. See Appendix A of this Prospectus.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the Common Shares’ market price or your overall returns. See “Risk Factors—Reinvestment Risk.”

Tax Risk. To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies (“RICs”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), the Fund must, among other things, derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy a diversification test on a quarterly basis. If the Fund fails to satisfy the qualifying income or diversification requirements in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. In order to be eligible for the relief provisions with respect to a failure to meet the diversification requirements, the Fund may be required to dispose of certain assets. If these relief provisions were not available to the Fund and it were to fail to qualify for treatment as a RIC for a taxable year, all of its taxable income (including its net capital gain) would be subject to tax at regular corporate rates (which the Tax Act (defined below) reduced to 21%) without any deduction for distributions to Shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

To qualify to pay exempt-interest dividends, which are treated as items of interest excludable from gross income for federal income tax purposes, at least 50% of the value of the total assets of the Fund must consist of obligations exempt from regular income tax as of the close of each quarter of the Fund’s taxable year. If the proportion of taxable investments held by the Fund exceeds 50% of the Fund’s total assets as of the close of any quarter of any Fund taxable year, the Fund will not for that taxable year satisfy the general eligibility test that otherwise permits it to pay exempt-interest dividends.

The value of the Fund’s investments and its NAV may be adversely affected by changes in tax rates and policies. Because interest income from municipal securities is normally not subject to regular federal income taxation, the attractiveness of municipal securities in relation to other investment alternatives is affected by changes in federal income tax rates or changes in the tax-exempt status of interest income from municipal securities. Any proposed or actual changes in such rates or exempt status, therefore, can significantly affect the demand for and supply, liquidity and marketability of municipal securities. This could in turn affect the Fund’s NAV and ability to acquire and dispose of municipal securities at desirable yield and price levels. Additionally, the Fund is not a suitable investment for individual retirement accounts, for other tax-exempt or tax-deferred accounts or for investors who are not sensitive to the federal income tax consequences of their investments.

Generally, the Fund’s investments in inverse floating rate securities do not generate taxable income.

See “Tax Matters.”

Leverage Risk. The use of leverage creates special risks for Common Shareholders, including the likelihood of greater volatility of NAV and

market price of, and distributions on, the Common Shares than a comparable portfolio without leverage. The use of leverage in a declining market will likely cause a greater decline in Common Share NAV, which may result in a greater decline of the Common Share price, than if the Fund were not to have used leverage.

The Fund will pay (and Common Shareholders will bear) any costs and expenses relating to the Fund’s use of leverage, which will result in a reduction in the NAV of and net income payable with respect to the Common Shares. Because of the costs of leverage, the Fund may incur losses even if the Fund has positive returns if they are not sufficient to cover the costs of leverage. NFALLC, based on its assessment of market conditions, may increase or decrease the Fund’s level of leverage. Such changes may impact the Fund’s distributions and the valuation of the Common Shares in the secondary market. There is no assurance that the Fund will utilize leverage or that the Fund’s use of leverage will be successful. Furthermore, the amount of fees paid to NFALLC and Nuveen Asset Management for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets, which may create an incentive for NFALLC to leverage the Fund or increase the Fund’s leverage. Certain types of leverage used by the Fund may result in the Fund being subject to certain covenants, asset coverage or other portfolio composition limits by its lenders, preferred purchasers, rating agencies that may rate the preferred securities, or reverse repurchase counterparties. Such limitations may be more stringent than those imposed by the 1940 Act and may impact whether the Fund is able to maintain its desired amount of leverage. At this time NFALLC does not believe that any such potential investment limitations will impede it from managing the Fund’s portfolio in accordance with its investment objectives and policies. See “Use of Leverage.” The Fund may invest in the securities of other investment companies, which may themselves be leveraged and therefore present similar risks to those described above and magnify the Fund’s leverage risk. The risk of loss attributable to the Fund’s use of leverage is borne by Common Shareholders.

Inverse Floating Rate Securities Risk. The Fund may invest in inverse floating rate securities. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a “tender option bond trust”) formed by a third party sponsor for the purpose of holding municipal bonds. See “The Fund’s Investments—Municipal Securities.” In general, income on inverse floating rate securities will decrease when interest rates increase and increase when interest rates decrease. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal rates fall. Inverse floating rate securities generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment. Investments in inverse floating rate securities may subject the Fund to the risks of reduced or eliminated interest payments and losses of principal. In addition, because of the leveraged nature of such investments, inverse floating rate securities will increase or decrease in value at a greater rate than the underlying fixed rate municipal bonds held by the tender option bond. As a result, the market value of such securities generally is more volatile than that of fixed rate securities.

The Fund may invest in inverse floating rate securities, issued by special purpose trusts that have recourse to the Fund. In NFALLC’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party granting liquidity to the floating rate security holders of a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the special purpose trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the special purpose trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third-party granting liquidity to the floating rate security holders the special purpose trust, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. In such instances, the Fund may be at risk of loss that exceeds its investment in the inverse floating rate securities.

The Fund’s investments in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund may be highly leveraged. The structure and degree to which the Fund’s inverse floating rate securities are highly leveraged will vary based upon a number of factors, including the size of the trust itself and the terms of the underlying municipal security. In the event of a significant decline in the value of an underlying security, the Fund may suffer losses in excess of the amount of its investment (up to an amount equal to the value of the municipal securities underlying the inverse floating rate securities) as a result of liquidating special purpose trusts or other collateral required to maintain the Fund’s anticipated effective leverage ratio.

The Fund’s investment in inverse floating rate securities creates leverage that provides an opportunity for increased Common Share net income and returns, but also creates the risk that Common Share long-term returns will be reduced if the cost of leverage exceeds the net return on the Fund’s investment portfolio.

Inverse floating rate securities have varying degrees of liquidity based upon the liquidity of the underlying securities deposited in a tender option bond trust. The market price of inverse floating rate securities is more volatile than the underlying securities due to leverage. The leverage attributable to such inverse floating rate securities may be “called away” on relatively short notice and therefore may be less permanent than more traditional forms of leverage. The Fund may be required to sell its inverse floating rate securities at less than favorable prices, or liquidate other Fund portfolio holdings in certain circumstances, including, but not limited to, the following:

•

If the Fund has a need for cash and the securities in a special purpose trust are not actively trading due to adverse market conditions;

•

If special purpose trust sponsors (as a collective group or individually) experience financial hardship and consequently seek to terminate their respective outstanding special purpose trusts; and

•

If the value of an underlying security declines significantly (to a level below the notional value of the floating rate securities issued by the trust) and if additional collateral has not been posted by the Fund.

See “Risk Factors—Inverse Floating Rate Securities Risk.”

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of Common Shares and distributions can decline. See “Risk Factors—Inflation Risk.”

Other Investment Companies Risk. The Fund may, subject to the limitations of the 1940 Act, invest in the securities of other investment companies including open-end and closed-end funds and ETFs. Such securities may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities, which would magnify the Fund’s leverage risk. The Fund, as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies’ expenses, including advisory fees. These expenses are in addition to the direct expenses of the Fund’s own operations. An ETF that is based on a specific index, whether stock or otherwise, may not be able to replicate and maintain exactly the composition and relative weighting of securities in the index. An ETF also incurs certain expenses not incurred by its applicable index. The market value of shares of ETFs and closed-end funds may differ from their NAV.

Derivatives Risk, Including the Risk of Swaps. The Fund’s use of derivatives involves risks different from, and possibly greater than, the risks associated with investing directly in the investments underlying the derivatives. Whether the Fund’s use of derivatives is successful will depend on, among other things, if Nuveen Asset Management correctly forecast market values, interest rates and other applicable factors. If Nuveen Asset Management incorrectly forecast these and other factors, the investment performance of the Fund will be unfavorably affected. In addition, the derivatives market is largely unregulated. It is possible that developments in the derivatives market could adversely affect the Fund’s ability to successfully use derivative instruments.

The Fund may enter into various types of derivatives transactions, including futures, options, swaps (including credit default swaps, interest rate swaps and total return swaps), among others. Like most derivative instruments, the use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In addition, the use of derivatives requires an understanding by Nuveen Asset Management not only of the referenced asset, rate or index, but also of the derivative contract itself and the markets in which they trade. Successful implementation of most hedging strategies would generate taxable income. The derivatives market is subject to a changing regulatory environment. It is possible that regulatory or other developments in the derivatives market could adversely affect the Fund’s ability to successfully use derivative instruments. See “Risk Factors—Derivatives Risk,” “Risk Factors—Counterparty Risk,” “Risk Factors—Hedging Risk,” “Risk Factors—Tax Risks” and the SAI.

Risks Related to the Fund’s Clearing Broker and Central Clearing Counterparty. The Commodity Exchange Act (“CEA”) requires swaps and futures clearing brokers registered as “futures commission merchants” to segregate all funds received from customers with respect to any orders for the purchase or sale of U.S. domestic futures contracts and cleared swaps from the brokers’ proprietary assets. Similarly, the CEA requires each futures commission merchant to hold in separate secure accounts all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and cleared swaps and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by a clearing broker from its customers are held by the clearing broker on a commingled basis in an omnibus account and may be invested in certain instruments permitted under applicable regulations. There is a risk that assets deposited by the Fund with any swaps or futures clearing broker as margin for futures contracts or cleared swaps may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing broker. In addition, the assets of the Fund might not be fully protected in the event of the Fund’s clearing broker’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker’s customers for the relevant account class.

Similarly, the CEA requires a clearing organization approved by the Commodity Futures Trading Commission (“CFTC”) as a derivatives clearing organization to segregate all funds and other property received from a clearing member’s clients in connection with domestic cleared futures and derivative contracts from any funds held at the clearing organization to support the clearing member’s proprietary trading. Nevertheless, all customer funds held at a clearing organization in connection with any futures contracts or derivatives contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. With respect to futures and options contracts, a clearing organization may use assets of a non-defaulting customer held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. As a result, in the event of a default or the clearing broker’s other clients or the clearing broker’s failure to extend its own funds in connection with any such default, the Fund may not be able to recover the full amount of assets deposited by the clearing broker on behalf of the Fund with the clearing organization. See “Risks—Risks Related to the Fund’s Clearing Broker and Central Clearing Counterparty.”

Counterparty Risk. Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to derivatives, insured municipal securities or other transactions supported by another party’s credit will affect the value of those instruments. Certain entities that have served as counterparties in the markets for these transactions have recently incurred significant losses and financial hardships including bankruptcy as a result of exposure to sub-prime mortgages and other lower quality credit investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. As a result, such hardships have reduced these entities’ capital and called into question their continued ability to perform their obligations under such transactions. By using such derivatives or other transactions, the

Fund assumes the risk that its counterparties could experience similar financial hardships. See “Risk Factors—Counterparty Risk.”

Hedging Risk. The Fund’s use of derivatives or other transactions to reduce risks involves costs and will be subject to Nuveen Asset Management’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that Nuveen Asset Management’s judgment in this respect will be correct. In addition, no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so. See “Risk Factors—Hedging Risk.”

Potential Conflicts of Interest Risk. NFALLC and Nuveen Asset Management each provide a wide array of portfolio management and other asset management services to a mix of clients and may engage in ordinary course activities in which their respective interests or those of their clients may compete or conflict with those of the Fund. For example, NFALLC and Nuveen Asset Management may provide investment management services to other funds and accounts that follow investment objectives similar to those of the Fund. In certain circumstances, and subject to its fiduciary obligations under the Investment Advisers Act of 1940, Nuveen Asset Management may have to allocate a limited investment opportunity among its clients, which include closed-end funds, open-end funds and other commingled funds. NFALLC and Nuveen Asset Management have each adopted policies and procedures designed to address such situations and other potential conflicts of interests. For additional information about potential conflicts of interest, and the way in which NFALLC and Nuveen Asset Management address such conflicts, please see the SAI.

Prepayment Risk. During periods of declining interest rates or for other purposes, issuers may exercise their option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding instruments. For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be increased. See “Risk Factors—Prepayment Risk.”

Anti-Takeover Provisions. The Fund’s Declaration of Trust (the “Declaration”) and the Fund’s By-Laws (the “By-Laws”) include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status. These provisions could have the effect of depriving Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares. See “Certain Provisions in the Declaration of Trust—Anti-Takeover Provisions” and “Risks—Anti-Takeover Provisions.”

In addition, an investment in the Fund’s Common Shares raises other risks, which are more fully disclosed in the “Risk Factors” section of this Prospectus.

Distributions

The Fund pays monthly distributions to Common Shareholders at a level rate (stated in terms of a fixed cents per Common Share dividend rate) based on the projected performance of the Fund. The Fund’s ability to maintain a level Common Share dividend rate will depend on a number of factors, including dividends payable on Preferred Shares. As portfolio and market conditions change, the rate of dividends on the Common Shares and

the Fund’s dividend policy could change. For each taxable year, the Fund will distribute all or substantially all of its net investment income (after it pays accrued dividends on Preferred Shares). While not currently anticipated, if the Fund makes total distributions during a given calendar year in an amount that exceeds the Fund’s net investment income and net capital gain for that calendar year, the excess would generally be treated by Common Shareholders as a return of capital for tax purposes. A return of capital reduces a shareholder’s tax basis, which could result in higher taxes when the shareholder sells his or her shares. This may cause the shareholder to pay taxes even if he or she sells shares for less than the original price. In addition, the Fund intends to distribute, at least annually, all or substantially all of its net capital gain and taxable ordinary income, if any, to Common Shareholders so long as the net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) and taxable ordinary income are not necessary to pay accrued dividends on, or redeem or liquidate, any Preferred Shares then outstanding or pay any interest and required principal payments on borrowings. You may elect to reinvest automatically some or all of your distributions in additional Common Shares under the Fund’s Dividend Reinvestment Plan.

The Fund might not distribute all or a portion of any net capital gain for a taxable year. If the Fund does not distribute all of its net capital gain for a taxable year, it will pay federal income tax on the retained gain. Provided that the Fund satisfies certain requirements, each Common Shareholder of record as of the end of the Fund’s taxable year (i) will include in income for federal income tax purposes, as long-term capital gain, his or her share of the retained gain, (ii) will be deemed to have paid his or her proportionate share of the tax paid by the Fund on such retained gain, and (iii) may be entitled to an income tax credit or refund for that share of the tax. The Fund will treat the retained capital gain amount as a substitute for equivalent cash distributions. See “Distributions” and “Dividend Reinvestment Plan.”

The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time subject to a finding by the Fund’s Board that such change is in the best interests of the Fund and its Common Shareholders, and may do so without prior notice to Common Shareholders.

Custodian and Transfer Agent

State Street Bank and Trust Company serves as custodian of the Fund’s assets. Computershare Inc. serves as the Fund’s transfer, shareholder services and dividend paying agent. See “Custodian and Transfer Agent.”

Special Tax Considerations

Because the Fund will invest, under normal circumstances, at least 80% of its Assets in municipal securities that pay interest exempt from regular federal and California income tax and, under normal circumstances, at least 100% of its Managed Assets in municipal securities that pay interest exempt from the federal alternative minimum tax applicable to individuals at the time of purchase, the dividends paid by the Fund will ordinarily be similarly exempt. To the extent the Fund invests in municipal securities of issuers outside of California and U.S. territories and possessions, dividends paid by the Fund may be subject to California income taxes. Such investments would not be included for purposes of calculating its 80% investment policy. Although the Fund expects that under normal circumstances it will not invest in municipal securities the interest on which is subject to the federal alternative minimum tax, at the time of purchase, to

the extent a portion of the income from municipal securities in which the Fund invests becomes may be subject to the federal alternative minimum tax, dividends paid by the Fund may be subject to the federal alternative minimum tax. See “Tax Matters.”

Voting Rights

The holders of the Fund’s Preferred Shares, voting as a separate class, would have the right to elect at least two Trustees at all times and to elect a majority of the Trustees in the event two full years’ dividends on the Preferred Shares, are unpaid. In each case, the remaining Trustees will be elected by holders of Common Shares and Preferred Shares, voting together as a single class. The holders of Preferred Shares will vote as a separate class or classes on certain other matters as required under the Declaration, the 1940 Act and Massachusetts law.

SUMMARY OF FUND EXPENSES

The purpose of the table below and the Examples below are to help you understand all fees and expenses that you, as a Common Shareholder, would bear directly or indirectly. The table shows the expenses of the Fund as a percentage of the average net assets applicable to Common Shares, and not as a percentage of total assets or Managed Assets.


Shareholder Transaction Expenses (as a percentage of offering price)
Maximum Sales Charge		4.00	%*
Offering Costs⁽¹⁾		0.31	%
Dividend Reinvestment Plan Fees⁽²⁾	$	2.50

*	A maximum sales charge of 4.00% applies only to offerings pursuant to a syndicated underwriting. The maximum sales charge for offerings made at-the-market is 1.00%. There is no sales charge for offerings pursuant to a private transaction.


	As a Percentage of Net Assets Attributable to Common Shares⁽³⁾
Annual Expenses
Management Fees		0.95	%
Fees on MFP Shares, VRDP Shares and Interest and Related Expenses from Inverse Floaters⁽⁴⁾		1.33	%
Other Expenses⁽⁵⁾		0.09	%

Total Annual Expenses		2.37	%

(1)	Assuming a Common Share price of $13.32 (the Fund’s closing price on the NYSE on April 26, 2018).

(2)	You will be charged a $2.50 service charge and pay brokerage charges if you direct ComputerShare Inc. and ComputerShare Trust Company, N.A., as agent for the Common Shareholders (the “Plan Agent”), to sell your Common Shares held in a dividend reinvestment account.

(3)	Stated as a percentage of average net assets attributable to Common Shares for the fiscal year ended February 28, 2018.

(4)

Currently, the Fund employs leverage through its investments in inverse floating rate securities, its outstanding Variable Rate Demand Preferred Shares, and its outstanding MuniFund Preferred Shares. Fees on MFP Shares, VRDP Shares and Interest and Related Expenses from Inverse Floaters has been restated using current fees as if they had been in effect during the previous fiscal year. Fees on MFP and VRDP Shares assume annual dividends paid, annual remarketing fees and amortization of offerings costs for both MFP and VRDP Shares, and annual liquidity fees for VRDP Shares. Interest and Related Expenses from Inverse Floaters include interest expense attributable to inverse floating rate securities created by selling a fixed-rate bond to a broker dealer for deposit into the special purpose trust and receiving in turn the residual interest in the trust (“self-deposited inverse floating rate securities”). To the extent the Fund creates self-deposited inverse floating rate securities, the Fund recognizes interest expense because accounting rules require the Fund to treat interest paid by such trusts as having been paid (indirectly) by the Fund. Because the Fund also recognizes a corresponding amount of additional interest earned (also indirectly), the Fund’s NAV per share, net investment income and total return are not affected by this accounting treatment. The actual fees on MFP and VRDP Shares and interest and related expenses from inverse floaters incurred in the future may be higher or lower. If short-term market interest rates rise in the future, and if the Fund continues to maintain leverage the cost of which is tied to short-term interest rates, the Fund’s interest expenses on its short-term borrowings can be expected to rise in tandem. The Fund’s use of leverage will increase the amount of management fees paid to the NFALLC and Nuveen Asset Management.

(5)	Other Expenses is based on estimated amounts for the current fiscal year. Expenses attributable to the Fund’s investments, if any, in other investment companies are currently estimated not to exceed 0.01%. See “Portfolio Composition—Other Investment Companies” in the SAI.

Examples

The following examples illustrate the expenses, including the applicable transaction fees (referred to as the “Maximum Sales Charge” in the fee table above), if any, and estimated offering costs of $3.10 that a Common Shareholder would pay on a $1,000 investment that is held for the time periods provided in the table. Each example assumes that all dividends and other distributions are reinvested in the Fund and that the Fund’s Total Annual Expenses, as provided above, remain the same. The examples also assume a 5% annual return.⁽¹⁾

Example # 1 (At-the-Market Transaction)

The following example assumes a transaction fee of 1.00%, as a percentage of the offering price.


1 Year	3 Years		5 Years		10 Years
$37	$	86	$	138	$	280

Example # 2 (Underwriting Syndicate Transaction)

The following example assumes a transaction fee of 4.00%, as a percentage of the offering price.


1 Year	3 Years		5 Years		10 Years
$66	$	114	$	164	$	302

Example # 3 (Privately Negotiated Transaction)

The following example assumes there is no transaction fee.


1 Year	3 Years		5 Years		10 Years
$27	$	77	$	129	$	273

The examples should not be considered a representation of future expenses. Actual expenses may be greater or less than those shown above.

(1)	The examples assume that all dividends and distributions are reinvested at Common Share NAV. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

FINANCIAL HIGHLIGHTS

The following Financial Highlights table is intended to help a prospective investor understand the Fund’s financial performance for the periods shown. Certain information reflects financial results for a single Common Share of the Fund. The total returns in the table represent the rate an investor would have earned or lost on an investment in Common Shares of the Fund (assuming reinvestment of all dividends). The Fund’s annual financial statements as of and for the fiscal years ended February 28/29, 2018, 2017, 2016 and 2015, including the financial highlights for the fiscal years then ended, have been audited by KPMG LLP (“KPMG”), an independent registered public accounting firm. KPMG has not reviewed or examined any records, transactions or events after the date of such reports. The information with respect to the fiscal years ended prior to February 28, 2015 has been audited by other auditors. A copy of the Annual Report may be obtained from www.sec.gov or by visiting www.nuveen.com. The information contained in, or that can be accessed through, the Fund’s website is not part of this Prospectus. Past results are not indicative of future performance.

(a)	The amounts shown are based on Common Share equivalents.

(b)

Total Return Based on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

Total Return Based on Common Share NAV is the combination of changes in Common Share NAV, reinvested dividend income at NAV and reinvested capital gains distributions at NAV, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending NAV. The actual reinvest price for the last dividend declared in the period may often be based on the Fund’s market price (and not its NAV), and therefore may be different from the price used in the calculation. Total returns are not annualized.

(c)	Ratios do not reflect the effect of dividend payments to Auction Rate Preferred shareholders, where applicable; Net Investment Income (Loss) ratios reflect income earned and expenses incurred on assets attributable to Auction Rate Preferred Shares (“ARPS”) and/or VRDP Shares, where applicable.

(d)	After expense reimbursement from the Adviser, where applicable. As of November 30, 2010, the Adviser is no longer contractually reimbursing the Fund for any fees or expenses.

(e)

The expense ratios reflect, among other things, all interest expense and other costs related to VRDP Shares, as described in Note 4—Fund Shares, Preferred Shares, and/or the interest expense deemed to have been paid by the Fund on the floating rate certificates issued by the special purpose trusts for the self-deposited inverse floaters held by the Fund, as described in Footnote 3—Portfolio Securities and Investment in Derivatives, Inverse Floating Rate Securities, in the most recent shareholder report, as follows:

During the fiscal year ended February 28, 2015, NFALLC voluntarily reimbursed the Fund for certain expenses incurred in connection with a equity shelf program. As a result, the Expenses and Net Investment Income (Loss) Ratios to Average Net Assets reflect this voluntary expense reimbursement from NFALLC. The Expenses and Net Investment Income (Loss) Ratios to Average Net Assets excluding this expense reimbursement from NFALLC are 1.63% and 5.51%, respectively.

(g)	Portfolio Turnover Rate is calculated based on the lesser of long-term purchases or sales divided by the average long-term market value during the period.

USE OF PROCEEDS

The net proceeds from the issuance of Common Shares hereunder will be used by the Fund to invest in securities in accordance with the Fund’s investment objectives and policies as stated below. Pending investment, the timing of which may vary depending on the size of the investment but in no case is expected to exceed 30 days, it is anticipated that the proceeds will be invested in high-quality, short-term investments. See “Risk Factors—Leverage Risk” and “Use of Leverage.”

THE FUND’S INVESTMENTS

Investment Objectives

The Fund’s investment objectives are:

•

to provide current income exempt from regular federal income tax, the federal alternative minimum tax applicable to individuals and California income tax; and

•

to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal securities that NFALLC and/or Nuveen Asset Management believes are underrated or undervalued or that represent municipal market sectors that are undervalued.

securities should ultimately reflect their true value. Accordingly, “enhancement of portfolio value relative to the municipal bond market” refers to the Fund’s objective of attempting to realize above-average capital appreciation in a rising market, and to experience less than average capital losses in a declining market. Thus, the Fund’s secondary investment objective is not intended to suggest that capital appreciation is itself an objective of the Fund. Instead, the Fund seeks enhancement of portfolio value relative to the municipal bond market by prudent selection of municipal securities, regardless of which direction the market may move. Any capital appreciation realized by the Fund will generally result in the distribution of taxable capital gains to Common Shareholders. There can be no assurance that the Fund will achieve its investment objectives. See “The Fund’s Investments—Investment Policies.”

Investment Philosophy

Nuveen Asset Management believes that the unique tax treatment of municipal securities and the structural characteristics in the municipal securities market create attractive opportunities to enhance the after-tax total return and diversification of the investment portfolios of taxable investors. Nuveen Asset Management believes that these unique characteristics also present unique risks that may be managed to realize the benefits of the asset class.

After-Tax Income Potential. The primary source of total return from municipal securities comes from the tax-exempt income derived therefrom. Nuveen Asset Management believes that, at acceptable levels of credit risk and maturity principal risk, the municipal securities market offers the potential for higher after-tax income when compared with other fixed income markets.

Managing Multi-Faceted Risks. Risk in the municipal securities market is derived from multiple sources, including credit risk at the issuer and sector levels, structural risks such as call risk, yield curve risk, and legislative and tax-related risks. Nuveen Asset Management believes that managing these risks at both the individual security and Fund portfolio levels is an important element of realizing the after-tax income and total return potential of the asset class.

Opportunities to Identify Underrated and Undervalued Municipal Securities. Within the state and national municipal securities markets, there are issuers with a wide array of financing purposes, security terms, offering structures and credit quality. Nuveen Asset Management believes that the size, depth and other characteristics of the state and national municipal securities markets offer a broad opportunity set of individual issuers in securities that may be underrated and undervalued relative to the general market.

Market Inefficiencies. Nuveen Asset Management believes that the scale and intricacy of the municipal securities market often results in pricing anomalies and other inefficiencies that can be identified and capitalized on through trading strategies.

Investment Process

Nuveen Asset Management believes that a bottom-up, value-oriented investment strategy that seeks to identify underrated and undervalued securities and sectors is positioned to capture the opportunities inherent in the municipal securities market and potentially outperform the general municipal securities market over time. The primary elements of Nuveen Asset Management’s investment process are:

Credit Analysis and Surveillance. Nuveen Asset Management focuses on bottom-up, fundamental analysis of municipal securities issuers. Analysts screen each sector for issuers that meet the fundamental tests of creditworthiness and favor those securities with demonstrable growth potential, solid coverage of debt service and a priority lien on hard assets, dedicated revenue streams or tax resources. As part of Nuveen Asset Management’s overall risk management process, analysts actively monitor the credit quality of portfolio holdings.

Sector Analysis. Organized by sector, analysts continually assess the key issues and trends affecting each sector in order to maintain a sector outlook. Evaluating such factors as historical default rates and average credit spreads within each sector, analysts provide top-down analysis that supports decisions to overweight or underweight a given sector in a portfolio.

Diversification. Nuveen Asset Management seeks to invest in a large number of sectors, states and specific issuers in order to help insulate a portfolio from events that affect any individual industry, geographic location or credit. Portfolio managers normally seek to limit exposure to individual credits over the long-term. Portfolio managers also seek to diversify other portfolio level risks, including exposure to calls, and to manage a portfolio’s interest rate sensitivity within tolerance bands relative to the relevant benchmark.

Trading Strategies. Through its trading strategies, Nuveen Asset Management seeks to enhance portfolio value by trading to take advantage of inefficiencies found in the municipal market. This may entail selling issues Nuveen Asset Management deems to be overvalued and purchasing issues Nuveen Asset Management considers to be undervalued.

Sell Discipline. Nuveen Asset Management generally sells securities when it (i) determines a security has become overvalued or over-rated, (ii) identifies credit deterioration, or (iii) modifies a portfolio strategy, such as sector allocation. Nuveen Asset Management may also sell securities when such securities exceed the portfolio’s diversification targets.

Investment Policies

Under normal circumstances, the Fund invests its Managed Assets in a portfolio of municipal securities that pay interest that is exempt from regular federal income tax, the federal alternative minimum tax applicable to individuals and California federal income tax. It is a fundamental policy that, under normal circumstances, the Fund invests at least 80% of its Assets in municipal securities and other related investments, the income from which is exempt from regular federal and California income taxes. As a non-fundamental policy which may be changed by the Fund’s Board without shareholder notice, under normal circumstances, the Fund invests 100% of its Managed Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase. As a non-fundamental policy subject to change by the Fund’s Board upon 60 days’ notice to shareholders, under normal circumstances, the Fund invests at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase.

As a non-fundamental policy subject to change by the Fund’s Board upon 60 days’ notice to the shareholders, under normal circumstances, the Fund will invest at least 80% of its Managed Assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one NRSRO or are unrated but judged to be of comparable quality by NFALLC and/or Nuveen Asset Management. Also, as a non-fundamental policy, the Fund may invest up to 20% of its Managed Assets in municipal securities that, at the time of investment, are rated below investment grade or are unrated but judged to be of comparable quality by NFALLC and/or Nuveen Asset Management. Additionally, as a non-fundamental policy, no more than 10% of the Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of NFALLC and/or comparable quality by Nuveen Asset Management. The Fund may invest in distressed securities. The Fund may not invest in the securities of an issuer which, at the time of investment, is in default on its obligations to pay principal or interest thereon when due or that is involved in a bankruptcy proceeding (i.e., rated below C-, at the time of investment); provided, however, that Nuveen Asset Management may determine that it is in the best interest of shareholders in pursuing a workout arrangement with issuers of defaulted securities to make loans to the defaulted issuer or another party, or purchase a debt, equity or other interest from the defaulted issuer or another party, or take other related or similar steps involving the investment of additional monies, but only if that issuer’s securities are already held by the Fund. The Fund may invest up to 15% of its Managed Assets in inverse floating rate securities. The economic

effect of leverage through the Fund’s purchase of inverse floating rate securities creates an opportunity for increased net income and returns, but also creates the possibility that the Fund’s long-term returns will be diminished if the cost of leverage exceeds the return on the inverse floating rate securities purchased by the Fund.

Securities of below investment grade quality (Ba/BB or below) are commonly referred to as “junk bonds.” Issuers of securities rated Ba/BB or B are regarded as having current capacity to make principal and interest payments but are subject to business, financial or economic conditions which could adversely affect such payment capacity. Municipal securities rated Baa or BBB are considered “investment grade” securities; municipal securities rated Baa are considered medium grade obligations which lack outstanding investment characteristics and have speculative characteristics, while municipal securities rated BBB are regarded as having adequate capacity to pay principal and interest. Municipal securities rated AAA in which the Fund may invest may have been so rated on the basis of the existence of insurance guaranteeing the timely payment, when due, of all principal and interest. Municipal securities rated below investment grade quality are obligations of issuers that are considered predominately speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Municipal securities rated below investment grade tend to be less marketable than higher-quality securities because the market for them is less broad. The market for unrated municipal securities is even narrower. During periods of thin trading in these markets, the spread between bid and asked prices is likely to increase significantly and the Fund may have greater difficulty selling its portfolio securities. The Fund will be more dependent on NFALLC and/or Nuveen Asset Management’s research and analysis when investing in these securities.

The ratings of S&P, Moody’s and Fitch represent their opinions as to the quality of the municipal securities they rate. It should be emphasized, however, that ratings are general and are not absolute standards of quality. Consequently, municipal securities with the same maturity, coupon and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same yield.

The foregoing credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that an NRSRO downgrades its assessment of the credit characteristics of a particular issuer or that valuation changes of various bonds cause the Fund’s portfolio to fail to satisfy those policies. In determining whether to retain or sell such a security, NFALLC and/or Nuveen Asset Management may consider such factors as Nuveen Asset Management’s assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. See “—Municipal Securities,” below. The Fund may also invest in securities of other open- or closed-end investment companies (up to 10% of its total assets) that invest primarily in municipal bonds of the types in which the Fund may invest directly. See “—Other Investment Companies.”

As of March 31, 2018, the effective maturity of the Fund’s portfolio was 22.48 years. The Fund will generally invest in municipal securities with intermediate or long-term maturities. Generally, the Fund is expected to have an average effective maturity of 15 to 30 years. The average effective maturity of obligations held by the Fund may be shortened or lengthened, depending on market conditions. As a result, the Fund’s portfolio at any given time may include both long-term and intermediate-term municipal securities. Moreover, during temporary defensive periods (e.g., times when, in NFALLC’s opinion, temporary imbalances of supply and demand or other temporary dislocations in the tax-exempt bond market adversely affect the price at which long-term or intermediate-term municipal securities are available), and in order to help keep the Fund’s assets fully invested, the Fund may invest any percentage of its net assets in short-term investments including high quality, short-term debt securities that may be either tax-exempt or taxable. The Fund will generally select obligations which may not be redeemed at the option of the issuer for approximately seven to nine years.

premiums for insurance and the higher market price paid for insured obligations may reduce the Fund’s income. The insurance feature guarantees only the payment of principal and interest on the obligation when due and does not guarantee the market value of the insured obligations, which will fluctuate with the bond market and the financial success of the issuer and the insurer, and the effectiveness and value of the insurance itself is dependent on the continued creditworthiness of the insurer. No representation is made as to the insurers’ ability to meet their commitments.

Obligations of issuers of municipal securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Bankruptcy Reform Act of 1978. In addition, the obligations of such issuers may become subject to the laws enacted in the future by Congress, state legislatures or referenda extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon municipalities to levy taxes. There is also the possibility that, as a result of legislation or other conditions, the power or ability of any issuer to pay, when due, the principal of and interest on its municipal securities may be materially affected.

The Fund also may invest in certain derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts, or other derivative instruments. Nuveen Asset Management may use derivative instruments to seek to enhance return, to hedge some of the risk of the Fund’s investments in municipal securities or as a substitute for a position in the underlying asset. These types of hedging strategies may generate taxable income. As of February 28, 2018, the Fund was not invested in derivatives. See “The Fund’s Investments—Municipal Securities—Derivatives.”

The Fund cannot change its investment objectives without the approval of the holders of a “majority of the outstanding” Common Shares and Preferred Shares, voting together as a single class, and of the holders of a “majority of the outstanding” Preferred Shares, voting as a separate class, and with the prior written consent of the liquidity providers for VRDP Shares, such consent to be determined in each liquidity provider’s good faith discretion. A “majority of the outstanding,” under the 1940 Act, means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less. See “Description of Shares—Preferred Shares—Voting Rights” for additional information with respect to the voting rights of Fund shareholders.

As of March 31, 2018, approximately 87% of the Fund’s Managed Assets were invested in municipal securities rated investment grade by an NRSRO (including S&P, Moody’s or Fitch). The relative percentages of the value of the investments attributable to investment grade municipal securities and to below investment grade municipal securities could change over time as a result of rebalancing the Fund’s assets by Nuveen Asset Management, market value fluctuations, issuance of additional shares and other events.

The Fund is diversified for purposes of the 1940 Act. Consequently, as to 75% of its assets, the Fund may not invest more than 5% of its total assets in the securities of any single issuer.

Portfolio Composition and Other Information

The Fund’s portfolio will be composed principally of the following investments.

Municipal Securities

General. The Fund may invest in various municipal securities, including municipal bonds and notes, other securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular federal income tax, the federal alternative minimum tax applicable to individuals and California income tax. Municipal securities are generally debt obligations issued by state and local governmental entities and may be issued by U.S. territories to finance or refinance public projects such as roads, schools, and water supply systems. Municipal securities may also be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility and pollution control projects. Municipal securities may be issued on a long-term basis to provide permanent financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments and mortgage payments. Municipal securities may also be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. Municipal securities may be issued an purchased in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms including fixed coupon, variable rate, zero coupon, capital appreciation bonds, tender option bonds, and residual interest bonds or inverse floating rate securities; or acquired through investments in pooled vehicles, partnerships or other investment companies. Inverse floating rate securities are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and represent a leveraged investment in an underlying municipal security.

Municipal securities are either general obligation or revenue bonds and typically are issued to finance public projects (such as roads or public buildings), to pay general operating expenses, or to refinance outstanding debt.

General obligation bonds are backed by the full faith and credit or taxing authority of the issuer and may be repaid from any revenue source. Revenue bonds may be repaid only from the revenues of a specific facility or source. Municipal securities may also be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned industrial development and pollution control projects. However, the obligation to repay the principal and interest rests with the private entity involved, not with the public entity that issues the bonds. The Fund may also purchase other municipal securities that represent lease obligations, municipal notes, pre-refunded municipal securities, private activity bonds, tender option bonds and other related securities and derivative instruments that create exposure to municipal bonds, notes and securities and that provide for the payment of interest income that is exempt from regular federal and California income tax.

The municipal securities in which the Fund will invest are generally issued by the State of California, a municipality in California, or a political subdivision or agency or instrumentality of such state or municipality, and pay interest that, in the opinion of bond counsel to the issuer (or on the basis of other authority believed by Nuveen Asset Management to be reliable), is exempt from regular federal and California personal income taxes and is also exempt from the federal alternative minimum tax applicable to individuals. The Fund may invest in municipal securities issued by U.S. territories and possessions (such as Puerto Rico or Guam) that are exempt from regular federal and California personal income taxes.

The yields on municipal securities depend on a variety of factors, including prevailing interest rates and the condition of the general money market and the municipal bond market, the size of a particular offering, the maturity of the obligation and the rating of the issue. The market value of municipal securities will vary with

changes in interest rate levels and as a result of changing evaluations of the ability of their issuers to meet interest and principal payments.

A municipal security’s market value generally will depend upon its form, maturity, call features, and interest rate, as well as the credit quality of the issuer, all such factors examined in the context of the municipal securities market and interest rate levels and trends.

Maturity and Duration. The Fund will generally invest in California municipal securities with long-term maturities in order to maintain an average effective maturity of 15 to 30 years, but the average effective maturity of obligations held by the Fund may be shortened or lengthened, depending on market conditions and on an assessment by the Fund’s portfolio manager of which segments of the California municipal securities market offer the most favorable relative investment values and opportunities for tax-exempt income and total return. In comparison to maturity (which is the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments and call features in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. For example, the price of a bond with an effective duration of two years will rise (fall) two percent for every one percent decrease (increase) in its yield, and the price of a five-year duration bond will rise (fall) five percent for a one percent decrease (increase) in its yield. As of March 31, 2018, the average leverage-adjusted effective duration was 13.48 years.

Municipal Leases and Certificates of Participation. The Fund also may purchase municipal securities that represent lease obligations and certificates of participation in such leases. These carry special risks because the issuer of the securities may not be obligated to appropriate money annually to make payments under the lease. A municipal lease is an obligation in the form of a lease or installment purchase which is issued by a state or local government to acquire equipment and facilities. Income from such obligations is generally exempt from state and local taxes in the state of issuance. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment or facilities. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and result in a delay in recovering, or the failure to recover fully, the Fund’s original investment. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. In order to reduce this risk, the Fund will only purchase municipal securities representing lease obligations where Nuveen Asset Management believes the issuer has a strong incentive to continue making appropriations until maturity.

A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, an installment purchase agreement or other instruments. The certificates are typically issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days’ notice, of all or any part of the Fund’s participation interest in the underlying municipal securities, plus accrued interest.

Municipal Notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer’s receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue sharing programs. Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer’s payment obligations under the notes or that refinancing will be otherwise unavailable.

Pre-Refunded Municipal Securities. The principal of and interest on pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer. Under the recently enacted tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”), interest paid on a municipal bond issued after December 31, 2017 to advance refund another municipal bond is subject to federal income tax.

Private Activity Bonds. Private activity bonds, formerly referred to as industrial development bonds, are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues. The Fund’s distributions of its interest income from private activity bonds may subject certain investors to the federal alternative minimum tax.

Inverse Floating Rate Securities. Inverse floating rate securities (sometimes referred to as “inverse floaters”) are securities whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index. Generally, inverse floating rate securities represent beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds. The special purpose trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds) and inverse floating rate securities (sometimes referred to as inverse floaters or residual interest securities). Both classes of beneficial interests are represented by certificates. The short-term floating rate securities have first priority on the cash flow from the municipal bonds held by the special purpose trust. Typically, a third party, such as a bank, broker-dealer or other financial institution, grants the floating rate security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees. The

holder of the short-term floater effectively holds a demand obligation that bears interest at prevailing short-term, interest rates. However, the institution granting the tender option will not be obligated to accept tendered short-term floaters in the event of certain defaults or a significant downgrade in the credit rating assigned to the bond issuer. For its inverse floating rate investment, the Fund receives the residual cash flow from the special purpose trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security, the Fund as the holder of the inverse floater assumes the interest rate cash flow risk and the market value risk associated with the municipal security deposited into the special purpose trust. The volatility of the interest cash flow and the residual market value will vary with the degree to which the trust is leveraged. This is expressed in the ratio of the total face value of the short-term floaters in relation to the value of the residual inverse floaters that are issued by the special purpose trust. In addition, all voting rights and decisions to be made with respect to any other rights relating to the municipal bonds held in the special purpose trust are passed through to the Fund, as the holder of the residual interest securities.

Because increases in the interest rate on the short-term floaters reduce the residual interest paid on inverse floaters, and because fluctuations in the value of the municipal bond deposited in the special purpose trust affect the value of the inverse floater only, and not the value of the short-term floater issued by the trust, inverse floaters’ value is generally more volatile than that of fixed rate bonds. The market price of inverse floating rate securities is generally more volatile than the underlying securities due to the leveraging effect of this ownership structure. These securities generally will underperform the market of fixed rate bonds in a rising interest rate environment (i.e., when bond values are falling), but tend to outperform the market of fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, inverse floaters typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality, coupon, call provisions and maturity. Inverse floaters have varying degrees of liquidity based upon the liquidity of the underlying securities deposited in a special purpose trust.

The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In NFALLC’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party granting liquidity to the floating rate security holders of a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party granting liquidity to the floating rate security holders the special purpose trust, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. Such agreements may expose the Fund to a risk of loss that exceeds its investment in the inverse floating rate securities. Absent a shortfall and forbearance agreement, the Fund would not be required to make such a reimbursement. If the Fund chooses not to enter into such an agreement, the special purpose trust could be liquidated and the Fund could incur a loss. See also “Portfolio Composition and Other Information—Segregation of Assets” in the SAI.

The Fund may invest in both inverse floating rate securities and floating rate securities (as discussed below) issued by the same special purpose trust.

The Fund will segregate or earmark liquid assets with its custodian in accordance with the 1940 Act to cover its obligations with respect to its investments in special purpose trusts.

Investments in inverse floating rate securities create effective leverage. The use of leverage creates special risks for Common Shareholders. See “Leverage” and “Risks—Fund Level Risks—Leverage Risk” and “—Inverse Floating Rate Securities Risk.”

Floating Rate Securities. The Fund may also invest in floating rate securities issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal

securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, the Fund as the holder of the floating rate security relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal bond deposited in the trust and the application of the proceeds to pay off the floating rate securities. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate securities.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

When-Issued and Delayed Delivery Transactions. The Fund may buy and sell municipal securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date. This type of transaction may involve an element of risk because no interest accrues on the bonds prior to settlement and, because bonds are subject to market fluctuations, the value of the bonds at time of delivery may be less (or more) than cost. A separate account of the Fund will be established with its custodian consisting of cash, cash equivalents, or liquid securities having a market value at all times at least equal to the amount of the commitment. Income generated by any such assets which provide taxable income for federal income tax purposes is includable in the taxable income of the Fund and, to the extent distributed, will be taxable distributions to shareholders. The Fund may enter into contracts to purchase municipal bonds on a forward basis (i.e., where settlement will occur more than 60 days from the date of the transaction) only to the extent that the Fund specifically collateralizes such obligations with a security that is expected to be called or mature within sixty days before or after the settlement date of the forward transaction. The commitment to purchase securities on a when-issued, delayed delivery or forward basis may involve an element of risk because no interest accrues on the bonds prior to settlement and at the time of delivery the market value may be less than cost.

Zero Coupon Bonds. A zero coupon bond is a bond that typically does not pay interest either for the entire life of the obligation or for an initial period after the issuance of the obligation. When held to its maturity, the holder receives the par value of the zero coupon bond, which generates a return equal to the difference between the purchase price and its maturity value. A zero coupon bond is normally issued and traded at a deep discount from face value. This original issue discount (“OID”) approximates the total amount of interest the security will accrue and compound prior to its maturity and reflects the payment deferral and credit risk associated with the instrument. Because zero coupon securities and other OID instruments do not pay cash interest at regular intervals, the instruments’ ongoing accruals require ongoing judgments concerning the collectability of deferred payments and the value of any associated collateral. As a result, these securities may be subject to greater value fluctuations and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash on a current basis. Because zero coupon bonds, and OID instruments generally, allow an issuer to avoid or delay the need to generate cash to meet current interest payments, they may involve greater payment deferral and credit risk than coupon loans and bonds that pay interest currently or in cash. The Fund generally will be required to distribute dividends to shareholders representing the income of these instruments as it accrues, even though the Fund will not receive all of the income on a current basis or in cash. Thus, the Fund may have to sell other

investments, including when it may not be advisable to do so, and use the cash proceeds to make income distributions to its shareholders. For accounting purposes, these cash distributions to shareholders will not be treated as a return of capital.

Further, NFALLC collects management fees on the value of a zero coupon bond or OID instrument attributable to the ongoing non-cash accrual of interest over the life of the bond or other instrument. As a result, NFALLC receives non-refundable cash payments based on such non-cash accruals while investors incur the risk that such non-cash accruals ultimately may not be realized.

Structured Notes. The Fund may utilize structured notes and similar instruments for investment purposes and also for hedging purposes. Structured notes are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but not ordinarily below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending upon a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index or indices or other assets. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss. These types of investments may generate taxable income.

Inter-Fund Borrowing and Lending. The SEC has granted an exemptive order permitting the Nuveen registered open-end and closed-end funds, including the Fund, to participate in an inter-fund lending facility whereby those funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen funds will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet redemptions. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no fund may borrow on an unsecured basis through the Inter-Fund Program unless the fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing fund has a secured borrowing outstanding from any other lender, including but not limited to another fund, the inter-fund loan must be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value; (3) if a fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the fund may borrow through the inter-fund loan on a secured basis only; (4) no fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a fund’s inter-fund loans to any one fund shall not exceed 5% of the lending fund’s net assets; (6) the duration of inter-fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business days’ notice by a lending fund and may be repaid on any day by a borrowing fund. In addition, a Nuveen fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The Board of Trustees of the Nuveen Funds is responsible for overseeing the Inter-Fund Program. The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When a fund borrows money from another fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund

loan is not available from another fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Special Considerations Relating to California Municipal Securities

As described above, the Fund will invest at least 80% of its Assets in municipal securities and other related investments, the income from which is exempt from regular federal and California income tax. The Fund is therefore susceptible to political, economic or regulatory factors affecting issuers of California municipal securities. See “Concentration Risk in California Issuers” and Appendix A of this Prospectus (“Factors Affecting Municipal Securities in California”). Information regarding the financial condition of the State of California is ordinarily included in various public documents issued thereby, such as the official statements prepared in connection with the issuance of general obligation bonds of the State of California. Such official statements may be obtained by contacting the State Treasurer’s Office at 800-900-3873 or at www.treasurer.ca.gov. Complete text of the current budget, the proposed 2017-18 fiscal year budget and prior budgets may be found at the electronic budget website of the Department of Finance (www.ebudget.ca.gov). Complete text of the State Controller’s monthly cash reports may be accessed at the State Controller’s website (www.sco.ca.gov).

The State of California is a party to numerous legal proceedings, many of which normally occur in governmental operations. Information regarding some of the more significant litigation pending against the State would ordinarily be included in various public documents issued thereby, such as the official statements referred to above prepared in connection with the issuance of general obligation bonds of California.

The Legislative Analyst’s Office (the “LAO”) has released several reports which include their estimates and assessments of State budget acts and associated fiscal and economic projections.

Derivatives

The Fund may invest in certain derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts or other derivative instruments. The Fund may also use credit default swaps and interest rate swaps. Credit default swaps may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of a reference obligation. If the Fund is a seller of a contract, the Fund would be required to pay the par (or other agreed upon) value of a referenced debt obligation to the counterparty in the event of a default or other credit event by the reference issuer, such as a U.S. or foreign corporate issuer, with respect to such debt obligations. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. As the seller, the Fund would be subject to investment exposure on the notional amount of the swap. If the Fund is a buyer of a contract, the Fund would have the right to deliver a referenced debt obligation and receive the par (or other agreed-upon) value of such debt obligation from the counterparty in the event of a default or other credit event (such as a credit downgrade) by the reference issuer, such as a U.S. or foreign corporation, with respect to its debt obligations. In return, the Fund would pay the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the counterparty would keep the stream of payments and would have no further obligations to the Fund. Interest rate swaps involve the exchange by the Fund with a counterparty of their

respective commitments to pay or receive interest, such as an exchange of fixed-rate payments for floating rate payments. The Fund will usually enter into interest rate swaps on a net basis; that is, the two payment streams will be netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments.

See “Hedging Strategies and other Uses of Derivatives” and “Segregation of Assets” in the SAI.

The requirements for qualification as a RIC may also limit the extent to which the Fund may invest in futures, options on futures and swaps. See “Tax Matters.”

NFALLC and Nuveen Asset Management may use derivative instruments to seek to enhance return, to hedge some of the risk of the Fund’s investments in municipal securities or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income. With respect to the Fund’s investment policies, for purposes of calculating net assets, the Fund will value eligible derivatives at fair value or market value instead of notional value.

There is no assurance that these derivative strategies will be available at any time or that NFALLC and Nuveen Asset Management will determine to use them for the Fund or, if used, that the strategies will be successful.

Swap Transactions. The Fund may enter into total return, interest rate and credit default swap agreements and interest rate caps, floors and collars. The Fund may also enter into options on the foregoing types of swap agreements (“swap options”).

The Fund may enter into swap transactions for any purpose consistent with its investment objectives and strategies, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, as a duration management technique, to reduce risk arising from the ownership of a particular instrument, or to gain exposure to certain sectors or markets in the most economical way possible.

Swap agreements are two party contracts entered into primarily by institutional investors for a specified period of time. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on a particular predetermined asset, reference rate or index. The gross returns to be exchanged or swapped between the parties are generally calculated with respect to a notional amount, e.g., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a basket of securities representing a particular index. The notional amount of the swap agreement generally is only used as a basis upon which to calculate the obligations that the parties to the swap agreement have agreed to exchange. The Fund’s current obligations under a net swap agreement will be accrued daily (offset against any amounts owed to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by assets determined to be liquid by Nuveen Asset Management. See “—Segregation of Assets” below.

Interest Rate Swaps, Caps, Collars and Floors. Interest rate swaps are bilateral contracts in which each party agrees to make periodic payments to the other party based on different referenced interest rates (e.g., a fixed rate and a floating rate) applied to a specified notional amount. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate floor. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index rises above a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate cap. Interest rate collars involve selling a cap and purchasing a floor or vice versa to protect the Fund against interest rate movements exceeding given minimum or maximum levels.

The use of interest rate transactions, such as interest rate swaps and caps, is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security

transactions. Depending on the state of interest rates in general, the Fund’s use of interest rate swaps or caps could enhance or harm the overall performance of the Fund’s common shares. To the extent there is a decline in interest rates, the value of the interest rate swap or cap could decline, and could result in a decline in the NAV of the common shares. In addition, if short-term interest rates are lower than the Fund’s fixed rate of payment on the interest rate swap, the swap will reduce common share net earnings. If, on the other hand, short-term interest rates are higher than the fixed rate of payment on the interest rate swap, the swap will enhance common share net earnings. Buying interest rate caps could enhance the performance of the common shares by providing a maximum leverage expense. Buying interest rate caps could also decrease the net earnings of the common shares in the event that the premium paid by the Fund to the counterparty exceeds the additional amount such Fund would have been required to pay had it not entered into the cap agreement.

Total Return Swaps. In a total return swap, one party agrees to pay the other the “total return” of a defined underlying asset during a specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A total return swap may be applied to any underlying asset but is most commonly used with equity indices, single stocks, bonds and defined baskets of loans and mortgages. The Fund might enter into a total return swap involving an underlying index or basket of securities to create exposure to a potentially widely diversified range of securities in a single trade. An index total return swap can be used by the portfolio managers to assume risk, without the complications of buying the component securities from what may not always be the most liquid of markets. In connection with the Fund’s position in a swap contract, the Fund will segregate liquid assets or will otherwise cover its position in accordance with applicable SEC requirements. See “—Segregation of Assets” below.

Credit Default Swaps. A credit default swap is a bilateral contract that enables an investor to buy or sell protection against a defined-issuer credit event. The Fund may enter into credit default swap agreements either as a buyer or a seller. The Fund may buy protection to attempt to mitigate the risk of default or credit quality deterioration in an individual security or a segment of the fixed income securities market to which it has exposure, or to take a “short” position in individual bonds or market segments which it does not own. The Fund may sell protection in an attempt to gain exposure to the credit quality characteristics of particular bonds or market segments without investing directly in those bonds or market segments. As the buyer of protection in a credit default swap, the Fund would pay a premium (by means of an upfront payment or a periodic stream of payments over the term of the agreement) in return for the right to deliver a referenced bond or group of bonds to the protection seller and receive the full notional or par value (or other agreed upon value) upon a default (or similar event) by the issuer(s) of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Fund. Thus, the cost to the Fund would be the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Fund bears the risk that the protection seller may fail to satisfy its payment obligations.

If the Fund is a seller of protection in a credit default swap and no credit event occurs, the Fund would generally receive an up-front payment or a periodic stream of payments over the term of the swap. If a credit event occurs, however, generally the Fund would have to pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. As the protection seller, the Fund effectively adds the economic equivalent of leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. Thus, the Fund bears the same risk as it would by buying the reference obligations directly, plus the additional risks related to obtaining investment exposure through a derivative instrument discussed below under “Risks Associated with Swap Transactions.” If the Fund writes credit default swaps, it will segregate the full notional amount of the credit default swap to cover its obligation thereunder.

Swap Options. A swap option is a contract that gives a counterparty the right (but not the obligation), in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement at some designated future time on specified terms. A cash-settled option on a swap gives the purchaser the right, in return for the premium paid, to receive an amount of cash equal to the value of the underlying swap as of the exercise date. The Fund may write (sell) and purchase put and call swap options. Depending on the terms of the particular option agreement, the Fund generally would incur a greater degree of risk when it writes a swap option than when it purchases a swap option. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swap option, upon exercise of the option the Fund would become obligated according to the terms of the underlying agreement.

Risks Associated with Swap Transactions. The use of swap transactions is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions. If NFALLC and/or Nuveen Asset Management is incorrect in its forecasts of default risks, market spreads or other applicable factors or events, the investment performance of the Fund would diminish compared with what it would have been if these techniques were not used. As the protection seller in a credit default swap, the Fund effectively adds the economic equivalent of leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. The Fund generally may only close out a swap, cap, floor, collar or other two-party contract with its particular counterparty, and generally may only transfer a position with the consent of that counterparty. In addition, the price at which the Fund may close out such a two party contract may not correlate with the price change in the underlying reference asset. If the counterparty defaults, the Fund will have contractual remedies, but there can be no assurance that the counterparty will be able to meet its contractual obligations or that the Fund will succeed in enforcing its rights. It also is possible that developments in the derivatives market, including potential government regulation, could adversely affect the Fund’s ability to terminate existing swap or other agreements or to realize amounts to be received under such agreements.

Futures and Options on Futures Generally. The Fund may attempt to hedge all or a portion of its investment portfolio against market risk by engaging in transactions in financial futures contracts, options on financial futures or options that either are based on an index of long-term municipal securities (i.e., those with average remaining maturities of more than 15 years) or relate to debt securities whose prices Nuveen Asset Management anticipates to correlate with the prices of the municipal securities the Fund owns. To accomplish such hedging, the Fund may take an investment position in a futures contract or in an option which is expected to move in the opposite direction from the position being hedged. Hedging may be utilized to reduce the risk that the value of securities the Fund owns may decline on account of an increase in interest rates and to hedge against increases in the cost of the securities the Fund intends to purchase as a result of a decline in interest rates. The use of futures and options for hedging purposes can be expected to result in taxable income or gain. The Fund currently intends to allocate any taxable income or gain proportionately between its common shares and its Preferred Shares. See “Tax Matters.” If futures are used for hedging purposes, there can be no guarantee that there will be a correlation between price movements in the futures contract and in the underlying financial instruments that are being hedged. This could result from differences between the financial instruments being hedged and the financial instruments underlying the standard contracts available for trading (e.g., differences in interest rate levels, maturities and the creditworthiness of issuers) among other factors. In addition, price movements of futures contracts may not correlate perfectly with price movements of the financial instruments underlying the futures contracts due to certain market distortions. A futures contract is an agreement between two parties to buy and sell a security, index or interest rate (each a “financial instrument”) for a set price on a future date. Certain futures contracts, such as futures contracts relating to individual securities, call for making or taking delivery of the underlying financial instrument. However, these contracts generally are closed out before delivery by entering into an offsetting purchase or sale of a matching futures contract (same exchange, underlying financial instrument, and delivery month). Other futures contracts, such as futures contracts on interest rates and indices, do not call for making or taking delivery of the underlying financial instrument, but rather are agreements pursuant to which two parties agree to take or make delivery of an amount of cash equal to the

difference between the value of the financial instrument at the close of the last trading day of the contract and the price at which the contract was originally written. These contracts also may be settled by entering into an offsetting futures contract.

Successful use of futures by the Fund also is subject to Nuveen Asset Management’s ability to predict correctly movements in the direction of the relevant market. For example, if the Fund uses futures to hedge against the possibility of a decline in the market value of securities held in its portfolio and the prices of such securities increase instead, the Fund will lose part or all of the benefit of the increased value of the securities which it has hedged because it will have offsetting losses in its futures positions. Furthermore, if in such circumstances the Fund has insufficient cash, it may have to sell securities to meet daily variation margin requirements. The Fund may have to sell such securities at a time when it may be disadvantageous to do so. The sale of financial futures or the purchase of put options on financial futures or on debt securities or indexes is a means of hedging against the risk of rising interest rates, whereas the purchase of financial futures or of call options on financial futures or on debt securities or indexes is a means of hedging the Fund’s portfolio against an increase in the price of securities such Fund intends to purchase. Writing a call option on a futures contract or on debt securities or indexes may serve as a hedge against a modest decline in prices of municipal securities held in the Fund’s portfolio, and writing a put option on a futures contract or on debt securities or indexes may serve as a partial hedge against an increase in the value of municipal securities the Fund intends to acquire. The writing of these options provides a hedge to the extent of the premium received in the writing transaction. The Fund may not enter into a futures contract or related options or forward contracts if more than 30% of the Fund’s net assets would be represented by futures contracts or more than 5% of the Fund’s net assets would be committed to initial margin deposits and premiums on futures contracts and related options.

Subsequent payments to and from the FCM, called variation margin, will be made on a daily basis as the price of the underlying financial instrument fluctuates, making the futures contract more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the Fund as unrealized gains or losses. At any time prior to expiration of the futures contract, the Fund may elect to close the position by taking an opposite position that will operate to terminate its position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a gain or loss. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the Fund, the Fund may be entitled to the return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the Fund. Futures transactions also involve brokerage costs and the Fund may have to segregate additional liquid assets in accordance with applicable SEC requirements. See “Segregation of Assets” below.

A futures option gives the purchaser of such option the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price at any time during the period of the option. Upon exercise of a call option, the purchaser acquires a long position in the futures contract and the writer is assigned the opposite short position. Upon the exercise of a put option, the opposite is true.

movements of the portfolio securities being hedged. Losses may be incurred in hedging transactions, which could reduce the portfolio gains that might have been realized if the hedging transactions had not been entered into.

If the Fund engages in futures transactions or in the writing of options on futures, it will be required to maintain initial margin and maintenance margin and may be required to make daily variation margin payments in accordance with applicable rules of the exchanges and the CFTC. If the Fund purchases a financial futures contract or a call option or writes a put option in order to hedge the anticipated purchase of municipal securities, and if the Fund fails to complete the anticipated purchase transaction, the Fund may have a loss or a gain on the futures or options transaction that will not be offset by price movements in the municipal securities that were the subject of the anticipatory hedge. The cost of put options on debt securities or indexes effectively increases the cost of the securities subject to them, thereby reducing the yield otherwise available from these securities. If the Fund decides to use futures contracts or options on futures contracts for hedging purposes, the Fund will be required to establish an account for such purposes with one or more CFTC-registered futures commission merchants. A futures commission merchant could establish initial and maintenance margin requirements for the Fund that are greater than those which would otherwise apply to the Fund under applicable rules of the exchanges and the CFTC.

There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a derivatives or futures or a futures option position, and the Fund would remain obligated to meet margin requirements until the position is closed. Futures exchanges may limit the amount of fluctuation permitted in certain futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of the current trading session. Once the daily limit has been reached in a futures contract subject to the limit, no more trades may be made on that day at a price beyond that limit. The daily limit governs only price movements during a particular trading day and therefore does not limit potential losses because the limit may work to prevent the liquidation of unfavorable positions. For example, futures prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of positions and subjecting some holders of futures contracts to substantial losses.

Segregation of Assets

As a closed-end investment company registered with the SEC, the Fund is subject to the federal securities laws, including the 1940 Act, the rules thereunder, and various interpretive positions of the SEC and its staff. In accordance with these laws, rules and positions, the Fund must “set aside” (often referred to as “asset segregation”) liquid assets, or engage in other SEC or staff-approved measures, to “cover” open positions with respect to certain kinds of derivatives instruments. In the case of forward currency contracts that are not contractually required to cash settle, for example, the Fund must set aside liquid assets equal to such contracts’ full notional value while the positions are open. With respect to forward currency contracts that are contractually required to cash settle, however, the Fund is permitted to set aside liquid assets in an amount equal to the Fund’s daily marked-to-market net obligations (i.e., the Fund’s daily net liability) under the contracts, if any, rather than such contracts’ full notional value. The Fund reserves the right to modify its asset segregation policies in the future to comply with any changes in the positions from time to time articulated by the SEC or its staff regarding asset segregation.

To the extent that the Fund uses its assets to cover its obligations as required by the 1940 Act, the rules thereunder, and applicable positions of the SEC and its staff, such assets may not be used for other operational purposes. NFALLC and/or Nuveen Asset Management will monitor the Fund’s use of derivatives and will take action as necessary for the purpose of complying with the asset segregation policy stated above. Such actions may include the sale of the Fund’s portfolio investments.

The Fund may invest in inverse floating rate securities issued by special purpose trusts. With respect to such investments, the Fund will segregate or earmark assets in an amount equal to at least 100% of the face amount of the floating rate securities issued by such trusts.

Other Investment Companies

The Fund may invest in securities of other open- or closed-end investment companies (including ETFs) that invest primarily in municipal securities of the types in which the Fund may invest directly. The Fund may invest in investment companies that are advised by NFALLC, Nuveen Asset Management or their respective affiliates to the extent permitted by applicable law and/or pursuant to exemptive relief from the SEC. The Fund has not received or applied for, nor does it currently intend to apply for, any such relief. As a shareholder in an investment company, the Fund will bear its ratable share of that investment company’s expenses, and would remain subject to payment of the Fund’s advisory and administrative fees with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. The Fund will consider the investments of underlying investment companies when determining compliance with Rule 35d-1 under the 1940 Act and when determining compliance with its own concentration policy, in each case to the extent the Fund has sufficient information about such investments after making a reasonable effort to obtain current information about the investments of underlying companies.

Nuveen Asset Management will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available municipal security investments. In addition, because the securities of other investment companies may be leveraged, the Fund may indirectly be subject to those risks and magnify the Fund’s leverage risks described herein. As described in the section entitled “Risk Factors,” the NAV and market value of leveraged shares will be more volatile and the yield to Common Shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

Portfolio Turnover

The Fund may engage in portfolio trading when considered appropriate, but short-term trading will not be used as the primary means of achieving the Fund’s investment objectives. Although the Fund cannot accurately predict its annual portfolio turnover rate, it is generally not expected to exceed 25% under normal circumstances. For the fiscal year ended February 28, 2018, the Fund’s portfolio turnover rate was 14%. However, there are no limits on the Fund’s rate of portfolio turnover, and investments may be sold without regard to length of time held when, in Nuveen Asset Management’s opinion, investment considerations warrant such action. A higher portfolio turnover rate would result in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. Although these commissions and expenses are not reflected in the Fund’s “Total Annual Expenses” disclosed in this Prospectus, they will be reflected in the Fund’s total return. In addition, high portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when distributed to shareholders, will be taxable as ordinary income. See “Tax Matters.”

USE OF LEVERAGE

1.48%. For the period March 1, 2018 through April 23, 2018 the average liquidation value of the MFP Shares outstanding was $140,400,000 and the average annual dividend rate on the MFP Shares was 1.72%. As of April 23, 2018, the Fund’s leverage through Preferred Shares and through its investments in inverse floating rate securities was approximately 40% of its Managed Assets.

The Preferred Shares have seniority over the Common Shares. Changes in the value of the Fund’s bond portfolio, including costs attributable to Preferred Shares, will be borne entirely by Common Shareholders. If there is a net decrease (or increase) in the value of the Fund’s investment portfolio, the leverage will decrease (or increase) the NAV per Common Share to a greater extent than if the Fund were not leveraged. For tax purposes, the Fund is currently required to allocate net capital gain and other taxable income, if any, between Common Shares and Preferred Shares in proportion to total dividends paid to each class for the year in which the net capital gain or other taxable income is realized. If net capital gain or other taxable income is allocated to Preferred Shares (instead of solely tax-exempt income), the Fund will likely have to pay higher total dividends to preferred shareholders or make special payments to preferred shareholders to compensate them for the increased tax liability. This would reduce the total amount of dividends paid to the Common Shareholders.

The Fund may also borrow for temporary purposes permitted by the 1940 Act. The Fund, along with certain other funds managed by NFALLC (the “Participating Funds”), are party to a committed unsecured credit facility (the “Facility”) provided by a group of lender, under which Participating Funds may borrow for temporary purposes only. Outstanding balances drawn by the Fund, or a Participating Fund, will bear interest at a variable rate and is the liability of such Fund. The Facility is not intended for sustained levered investment purposes. A large portion of the Facility’s capacity (and corresponding annual costs, excluding interest cost) is currently allocated by NFALLC to a small number or Participating Funds, which does not include the Fund. The Facility has a 364-day term and will expire in July 2018 unless extended or renewed.

The Fund may reduce or increase leverage based upon changes in market conditions and anticipates that its leverage ratio will vary from time to time based upon variations in the value of the Fund’s holdings. So long as the net rate of income received on the Fund’s investments purchased with leverage proceeds exceeds the then current expense on any leverage, the investment of leverage proceeds will generate more net income than if the Fund had not used leverage. If so, the excess net income will be available to pay higher distributions to Common Shareholders. However, if the rate of net income received from the Fund’s portfolio investments purchased with leverage is less than the then current expense on outstanding leverage, the Fund may be required to utilize other Fund assets to make expense payments on outstanding leverage, which may result in a decline in Common Share NAV and reduced net investment income available for distribution to Common Shareholders. See “Risk Factors—Leverage Risk.”

Following an offering of additional Common Shares from time to time, the Fund’s leverage ratio will decrease as a result of the increase in net assets attributable to Common Shares. The Fund’s leverage ratio may decline further to the extent that the net proceeds of an offering of Common Shares are used to reduce the Fund’s leverage. A lower leverage ratio may result in lower (higher) returns to Common Shareholders over a period of time to the extent that net returns on the Fund’s investment portfolio exceed (fall below) its cost of leverage over that period, which lower (higher) returns may impact the level of the Fund’s distributions. See “Risk Factors—Leverage Risk.”

The Fund may use derivatives, such as interest rate swaps with varying terms, in order to manage the interest rate expense associated with all or a portion of its leverage. Interest rate swaps are bi-lateral agreements whereby parties agree to exchange future payments, typically based upon the differential of a fixed rate and a variable rate, on a specified notional amount. Interest rate swaps can enable a Fund to effectively convert its variable leverage expense to fixed, or vice versa. For example, if the Fund issues leverage having a short-term floating rate of interest, the Fund could use interest rate swaps to hedge against a rise in the short-term benchmark interest rates associated with its outstanding leverage. In doing so, the Fund would seek to achieve lower leverage costs, and thereby enhance Common Share distributions, over an extended period, which would

be the result if short-term interest rates on average exceed the fixed interest rate over the term of the swap. To the extent the fixed swap rate is greater than short-term market interest rates on average over the period, overall costs associated with leverage will increase (and thereby reduce distributions to Common Shareholders) than if the Fund had not entered into the interest rate swap(s).

The 1940 Act generally defines a “senior security” as any bond, debenture, note, or similar obligation or instrument constituting a security and evidencing indebtedness, and any stock of a class having priority over any other class as to distribution of assets or payment of dividends; however, the term does not include any promissory note or other evidence of indebtedness issued in consideration of any loan, extension, or renewal thereof, made for temporary purposes and in an amount not exceeding five percent of the value of the Fund’s total assets. A loan shall be presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed.

Under the 1940 Act, the Fund is not permitted to issue “senior securities representing indebtedness” if, immediately after the issuance of such senior securities representing indebtedness, the asset coverage ratio with respect to such senior securities would be less than 300%. “Senior securities representing indebtedness” include borrowings (including loans from financial institutions); debt securities; and other derivative investments or transactions such as reverse repurchase agreements and investments in inverse floating rate securities to the extent the Fund has not fully covered, segregated or earmarked cash or liquid assets having a market value at least equal to its future obligation under such instruments. With respect to any such senior securities representing indebtedness, asset coverage means the ratio which the value of the total assets of the Fund, less all liabilities and indebtedness not represented by senior securities (as defined in the 1940 Act), bears to the aggregate amount of such borrowing represented by senior securities representing indebtedness issued by the Fund.

Under the 1940 Act, the Fund is not permitted to issue “senior securities” that are Preferred Shares if, immediately after the issuance of Preferred Shares, the asset coverage ratio with respect to such Preferred Shares would be less than 200%. With respect to any such Preferred Shares, asset coverage means the ratio which the value of the total assets of the Fund, less all liabilities and indebtedness not represented by senior securities, bears to the aggregate amount of senior securities representing indebtedness of the Fund plus the aggregate liquidation preference of such Preferred Shares.

The Fund is limited by certain investment restrictions and may only issue senior securities that are preferred shares except the Fund may borrow money from a bank for temporary or emergency purposes or for repurchase of its shares only in an amount not exceeding one-third of the Fund’s total assets (including the amount borrowed) less the Fund’s liabilities (other than borrowings). See “Investment Restrictions” in the Statement of

Additional Information. These restrictions are fundamental and may not be changed without the approval of Common Shares and Preferred Shares voting together as a single class.

If the asset coverage with respect to any senior securities issued by the Fund declines below the required ratios discussed above (as a result of market fluctuations or otherwise), the Fund may sell portfolio securities when it may be disadvantageous to do so.

Certain types of leverage used by the Fund may result in the Fund being subject to certain covenants, asset coverage and, or other portfolio composition limits by its lenders, preferred securities purchasers, rating agencies that may rate preferred securities, or reverse repurchase agreement counterparties. Such limitations may be more stringent than those imposed by the 1940 Act and may impact whether the Fund is able to maintain its desired amount of leverage. At this time NFALLC does not believe that any such potential investment limitations will impede it from managing the Fund’s portfolio in accordance with its investment objective and policies.

Utilization of leverage is a speculative investment technique and involves certain risks to the Common Shareholders, including increased variability of the Fund’s net income, distributions and net asset value in relation to market changes. See “Risks—Fund Level Risks—Leverage Risk.” There is no assurance that the Fund will use leverage or that the Fund’s use of leverage will work as planned or achieve its goals.

Effects of Leverage

Assuming the utilization of leverage through the combination of Preferred Shares and Tender Option Bond Floaters (investments in inverse floating rate securities) in the aggregate amount of approximately 39% of the Fund’s Managed Assets, at an aggregate cost of leverage of 2.55%, the income generated by the Fund’s portfolio (net of non-leverage expenses) must exceed 0.99% in order to cover such costs of leverage. Of course, these numbers are merely estimates, used for illustration. Actual costs of leverage may vary frequently and may be significantly higher or lower than the rate estimated above.


Assumed Portfolio Total Return	-10	%	-5	%	0	%	5	%	10	%
Common Shares Total Return	-18.02	%	-9.83	%	-1.63	%	6.57	%	14.76	%

Common Share total return is composed of two elements—Common Share dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying dividends on Preferred Shares and other expenses associated with outstanding Preferred shares) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table assumes that the Fund is more likely to suffer capital losses than capital appreciation. For example, to assume a total return of 0%, the Fund must assume that the tax-exempt interest it receives on its municipal securities investments is entirely offset by losses in the value of those securities.

RISK FACTORS

Risk is inherent in all investing. Investing in any investment company security involves risk, including the risk that you may receive little or no return on your investment or even that you may lose part or all of your investment. Therefore, before investing you should consider carefully the following risks that you assume when you invest in Common Shares.

Investment and Market Risk

An investment in the Fund’s Common Shares are subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in Common Shares represents an indirect investment in the municipal securities owned by the Fund, substantially all of which are traded on a national exchange or in

the over-the-counter markets. Your Common Shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions. In addition, if the current national economic downturn deteriorates into a prolonged recession, the ability of municipalities to collect revenue and service their obligations could be materially and adversely affected.

Market Discount from Net Asset Value

Shares of closed-end investment companies like the Fund have during some periods traded at prices higher than NAV and have during other periods traded at prices lower than NAV. The Fund cannot predict whether Common Shares will trade at, above or below NAV. This characteristic is a risk separate and distinct from the risk that the Fund’s NAV could decrease as a result of investment activities. Investors bear a risk of loss to the extent that the price at which they sell their shares is lower in relation to the Fund’s NAV than at the time of purchase, assuming a stable NAV. Proceeds from the sale of Common Shares in this offering will be reduced by shareholder transaction costs (if applicable, which vary depending on the offering method used). The NAV per Common Share will be reduced by costs associated with any future issuances of Common Shares or Preferred Shares. Depending on the premium of Common Shares at the time of any offering of Common Shares hereunder, the Fund’s NAV may be reduced by an amount up to the offering costs (estimated to be an additional 0.31% of the offering price assuming a Common Share offering price of $13.32 (the Fund’s closing price on the NYSE on April 26, 2018)). The Common Shares are designed primarily for long-term investors, and you should not view the Fund as a vehicle for trading purposes.

Economic and Political Events Risk

The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds or moral obligation bonds). Such developments may adversely affect a specific industry or local political and economic conditions, and thus may lead to declines in the bonds’ creditworthiness and value.

Recent Market Circumstances

Since the financial crisis that started in 2008, the U.S. and many foreign economies continue to experience its after-effects. Conditions in the U.S. and many foreign economies have resulted, and may continue to result, in certain instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. These events have reduced the willingness and ability of some lenders to extend credit, and have made it more difficult for some borrowers to obtain financing on attractive terms, if at all. In some cases, traditional market participants have been less willing to make a market in some types of debt instruments, which has affected the liquidity of those instruments. During times of market turmoil, investors tend to look to the safety of securities issued or backed by the U.S. Treasury, causing the prices of these securities to rise and the yields to decline. Reduced liquidity in fixed income and credit markets may negatively affect many issuers worldwide. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time.

In response to the financial crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. In some countries where economic conditions are recovering, such countries are nevertheless perceived as still fragile. Withdrawal of government support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding, could adversely impact the value and liquidity of certain securities. The severity or duration of adverse economic

conditions may also be affected by policy changes made by governments or quasi-governmental organizations, including changes in tax laws. The impact of new financial regulation legislation on the markets and the practical implications for market participants may not be fully known for some time. Regulatory changes are causing some financial services companies to exit long-standing lines of business, resulting in dislocations for other market participants. In addition, the contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown and threats not to increase the federal government’s debt limit, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. The U.S. government has recently reduced federal corporate income tax rates, and future legislative, regulatory and policy changes may result in more restrictions on international trade, less stringent prudential regulation of certain players in the financial markets, and significant new investments in infrastructure and national defense. Markets may react strongly to expectations about the changes in these policies, which could increase volatility, especially if the markets’ expectations for changes in government policies are not borne out.

Changes in market conditions will not have the same impact on all types of securities. Interest rates have been unusually low in recent years in the United States and abroad. Because there is little precedent for this situation, it is difficult to predict the impact of a significant rate increase on various markets. For example, because investors may buy securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. Because of the sharp decline in the worldwide price of oil, there is a concern that oil producing nations may withdraw significant assets now held in U.S. Treasuries, which could force a substantial increase in interest rates. Regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. In addition, there is a risk that the prices of goods and services in the U.S. and many foreign economies may decline over time, known as deflation (the opposite of inflation). Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely. If a country’s economy slips into a deflationary pattern, it could last for a prolonged period and may be difficult to reverse. The precise details and the resulting impact of the United Kingdom’s vote to leave the European Union (“EU”), commonly referred to as “Brexit,” are not yet known. The effect on the United Kingdom’s economy will likely depend on the nature of trade relations with the EU and other major economies following its exit, which are matters to be negotiated. The outcomes may cause increased volatility and have a significant adverse impact on world financial markets, other international trade agreements, and the United Kingdom and European economies, as well as the broader global economy for some time.

The impact of these developments in the near- and long-term is unknown and could have additional adverse effects on economies, financial markets and asset valuations around the world.

Market Disruption and Geopolitical Risk

The aftermath of the war in Iraq, instability in Afghanistan, Pakistan, Egypt, Libya, Syria, Russia, Ukraine and the Middle East, possible terrorist attacks in the United States and around the world, growing social and political discord in the United States, the European debt crisis, the response of the international community—through economic sanctions and otherwise—to Russia’s recent annexation of the Crimea region of Ukraine and posture vis-a-vis Ukraine, further downgrade of U.S. Government securities and other similar events, may have long-term effects on the U.S. and worldwide financial markets and may cause further economic uncertainties in the United States and worldwide. The Fund does not know and cannot predict how long the securities markets may be affected by these events and the effects of these and similar events in the future on the U.S. economy and securities markets. The Fund may be adversely affected by abrogation of international agreements and national laws which have created the market instruments in which the Fund may invest, failure of the designated national and international authorities to enforce compliance with the same laws and agreements, failure of local, national and international organization to carry out their duties prescribed to them under the relevant agreements, revisions of these laws and agreements which dilute their effectiveness or conflicting interpretation of provisions

of the same laws and agreements. The Fund may be adversely affected by uncertainties such as terrorism, international political developments, and changes in government policies, taxation, restrictions on foreign investment and currency repatriation, currency fluctuations and other developments in the laws and regulations of the countries in which it is invested.

Legislation and Regulatory Risk

At any time after the date of this Prospectus, legislation or additional regulations may be enacted that could negatively affect the assets of the Fund, securities held by the Fund or the issuers of such securities. Changing approaches to regulation may have a negative impact on the entities and/or securities in which the Fund invests. Legislation or regulation may also change the way in which the Fund itself is regulated. Fund shareholders may incur increased costs resulting from such legislation or additional regulation. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Fund or will not impair the ability of the Fund to achieve its investment objectives.

For example, the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) is designed to impose stringent regulation on the over-the-counter derivatives market in an attempt to increase transparency and accountability and provides for, among other things, new clearing, execution, margin, reporting, recordkeeping, business conduct, disclosure, position limit, minimum net capital and registration requirements. Although the CFTC has released final rules under the Dodd- Frank Act, many of the provisions are subject to further final rulemaking, and thus the Dodd-Frank Act’s ultimate impact remains unclear.

The SEC also indicated that it may adopt new policies on the use of derivatives by registered investment companies. Such policies could affect the nature and extent of derivatives use by the Fund. While the nature of any such regulations, if adopted, is uncertain at this time, it is possible that such regulations could limit the implementation of the Fund’s use of derivatives, which could have an adverse effect on the Fund.

Additionally, the Fund is operated by persons who have claimed an exclusion, granted to operators of registered investment companies like the Fund, from registration as a “commodity pool operator” under Rule 4.5 promulgated by the CFTC pursuant to its authority under the CEA and, therefore, is not subject to registration or regulation as a “commodity pool operator.” As a result, the Fund is limited in its ability to use commodity futures (which include futures on broad-based securities indexes and interest rate futures) or options on commodity futures, engage in swaps transactions or make certain other investments (whether directly or indirectly through investments in other investment vehicles) for purposes other than bona fide hedging. With respect to transactions other than for bona fide hedging purposes, either: (1) the aggregate initial margin and premiums required to establish the Fund’s positions in such investments may not exceed 5% of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such investments); or (2) the aggregate net notional value of such instruments, determined at the time the most recent position was established, may not exceed 100% of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such positions). In addition to meeting one of the foregoing trading limitations, the Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the futures, options or swaps markets. If the Fund does not continue to claim the exclusion, it would likely become subject to registration and regulation as a commodity pool operator. The Fund may incur additional expenses as a result of the CFTC’s registration and regulatory requirements.

Economic and Political Events Risk

Impact of Offering Methods Risk

The issuance of Common Shares through the various methods described in this Prospectus may have an adverse effect on prices in the secondary market for the Fund’s Common Shares by increasing the number of Common Shares available for sale. In addition, the Common Shares may be issued at a discount to the market price for such shares, which may put downward pressure on the market price for Common Shares of the Fund.

Credit Risk

Credit risk is the risk that one or more municipal securities in the Fund’s portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer of the security experiences a decline in its financial status. In general, lower-rated municipal securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative impact on the Fund’s NAV or dividends. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. If a municipal security satisfies the rating requirements described above at the time of investment and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. If a downgrade occurs, Nuveen Asset Management will consider what action, including the sale of the security, is in the best interests of the Fund and its shareholders. This means that the Fund may be invested in municipal securities that have become involved in bankruptcy or insolvency proceedings; and may invest in municipal securities that are experiencing other financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities).

Below Investment Grade Risk

Municipal securities of below investment grade quality, commonly referred to as junk bonds, are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal when due, and are susceptible to default or decline in market value due to adverse economic and business developments. Also, to the extent that the rating assigned to a municipal security in the Fund’s portfolio is downgraded by any NRSRO, the market price and liquidity of such security may be adversely affected. The market values for municipal securities of below investment grade quality tend to be volatile, and these securities are less liquid than investment grade municipal securities. For these reasons, an investment in the Fund, compared with a portfolio consisting solely of investment grade securities, may experience the following:

•

increased price sensitivity resulting from changing interest rates and/or a deteriorating economic environment;

•

greater risk of loss due to default or declining credit quality;

•

adverse issuer specific events that are more likely to render the issuer unable to make interest and/or principal payments; and

•

Adverse changes in economic conditions are more likely to lead to a weakened capacity of a below investment grade issuer to make principal payments and interest payments compared to an investment grade issuer. The principal amount of below investment grade securities outstanding has proliferated in the past decade as an increasing number of issuers have used below investment grade securities for financing. The current downturn may severely affect the ability of highly leveraged issuers to service their debt obligations or to repay their obligations upon maturity. As the national economy experiences the current economic downturn, resulting in decreased tax and other revenue streams of municipal issuers, or in the event interest rates rise sharply, increasing the interest cost on variable rate instruments and negatively impacting economic activity, the number of defaults by below investment grade municipal issuers is likely to increase. Similarly, downturns in profitability in specific industries could adversely affect private activity bonds. The

market values of lower quality debt securities tend to reflect individual developments of the issuer to a greater extent than do higher quality securities, which react primarily to fluctuations in the general level of interest rates. Factors having an adverse impact on the market value of lower quality securities may have an adverse impact on the Fund’s NAV and the market value of its Common Shares. In addition, the Fund may incur additional expenses to the extent it is required to seek recovery upon a default in payment of principal or interest on its portfolio holdings. In certain circumstances, the Fund may be required to foreclose on an issuer’s assets and take possession of its property or operations. In such circumstances, the Fund would incur additional costs in disposing of such assets and potential liabilities from operating any business acquired.

The secondary market for below investment grade securities may not be as liquid as the secondary market for more highly rated securities, a factor that may have an adverse effect on the Fund’s ability to dispose of a particular security. There are fewer dealers in the market for below investment grade municipal securities than the market for investment grade municipal securities. The prices quoted by different dealers for below investment grade municipal securities may vary significantly, and the spread between the bid and ask price is generally much larger for below investment grade municipal securities than for higher quality instruments. Under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and these instruments may become illiquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower rated or unrated securities, under these circumstances, may be less than the prices used in calculating the Fund’s NAV.

Issuers of such below investment grade securities are highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with higher rated securities. For example, during an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of below investment grade securities may experience financial stress. During such periods, such issuers may not have sufficient revenues to meet their interest payment obligations. The issuer’s ability to service its debt obligations also may be adversely affected by specific developments, the issuer’s inability to meet specific projected forecasts or the unavailability of additional financing. The risk of loss from default by the issuer is significantly greater for the holders of below investment grade securities because such securities are generally unsecured and are often subordinated to other creditors of the issuer. Prices and yields of below investment grade securities will fluctuate over time and, during periods of economic uncertainty, volatility of below investment grade securities may adversely affect the Fund’s NAV. In addition, investments in below investment grade zero coupon bonds rather than income- bearing below investment grade securities, may be more speculative and may be subject to greater fluctuations in value due to changes in interest rates.

The Fund may invest in distressed securities, which are securities issued by companies that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition by the Fund. The issuers of such securities may be in transition, out of favor, financially leveraged or troubled, or potentially troubled, and may be or have recently been involved in major strategic actions, restructurings, bankruptcy, reorganization or liquidation. These characteristics of these companies can cause their securities to be particularly risky, although they also may offer the potential for high returns. These companies’ securities may be considered speculative, and the ability of the companies to pay their debts on schedule could be affected by adverse interest rate movements, changes in the general economic climate, economic factors affecting a particular industry or specific developments within the companies. Distressed securities frequently do not produce income while they are outstanding and may require the Fund to bear certain extraordinary expenses in order to protect and recover its investment.

Investments in lower rated or unrated securities may present special tax issues for the Fund to the extent that the issuers of these securities default on their obligations pertaining thereto, and the federal income tax consequences to the Fund as a holder of such distressed securities may not be clear.

Reverse Repurchase Agreement Risk

Reverse repurchase agreements involve the sale of securities held by the Fund with an agreement to repurchase the securities at an agreed-upon price and date, thereby establishing an effective interest rate. The Fund’s use of reverse repurchase agreements, in economic essence, constitute a securitized borrowing by the Fund from the security purchaser. The Fund may enter into reverse repurchase agreements for the purpose of creating a leveraged investment exposure and, as such, their usage involves essentially the same risks associated with a leveraging strategy generally since the proceeds from these agreements may be invested in additional securities. However, the effective borrowing rate paid by the Fund to the reverse repurchase agreement counterparty will be treated as taxable income, unlike the effective borrowing rate paid by the fund on Preferred Shares or on inverse floating rate securities, where is generally tax-exempt to the recipient, meaning that the effective borrowing rate paid by the Fund on a reverse repurchase agreement would, all other things being equal, will tend to be higher than those other forms of leverage. Reverse repurchase agreements tend to be short-term in tenor, and there can be no assurances that the purchaser (lender) will commit to extend or “roll” a given agreement upon its agreed-upon repurchase date if such roll is requested by the Fund or an alternative purchaser can be identified on similar terms. Reverse repurchase agreements also involve the risk that the purchaser (lender) fails to return the securities as agreed upon, files for bankruptcy or becomes insolvent. The Fund may be restricted from taking normal portfolio actions during such time, could be subject to loss to the extent that the proceeds of the agreement are less than the value of securities subject to the agreement and may experience adverse tax consequences.

Interest Rate Risk

Generally, when market interest rates rise, bond prices fall, and vice versa. Interest rate risk is the risk that the municipal securities in the Fund’s portfolio will decline in value because of increases in market interest rates. As interest rates decline, issuers of municipal securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower-yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of securities, potentially locking in a below-market interest rate and reducing the Fund’s value. In typical market interest rate environments, the prices of longer-term municipal securities generally fluctuate more than prices of shorter-term municipal securities as interest rates change. In comparison to maturity (which is the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments and call features, in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. For example, the price of a bond with an effective duration of two years will rise (fall) two percent for every one percent decrease (increase) in its yield, and the price of a five-year duration bond will rise (fall) five percent for a one percent decrease (increase) in its yield. Greater sensitivity to interest rates typically corresponds to higher volatility and higher risk. Yield curve risk is the risk associated with either a flattening or steepening of the yield curve, which is a result of changing yields among comparable bonds with different maturities. When market interest rates, or yields, increase, the price of a bond will decrease and vice versa. When the yield curve shifts, the price of the bond, which was initially priced based on the initial yield curve, will change in price. If the yield curve flattens, then the yield spread between long- and short-term interest rates narrows, and the price of the bond will change accordingly. If the bond is short-term and the yield decreases, the price of this bond will increase. If the yield curve steepens, this means that the spread between long- and short-term interest rates increases. Therefore, long-term bond prices, like the ones held by the Fund, will decrease relative to short-term bonds. Changes in the yield curve are based on bond risk premiums and expectations of future interest rates. Because the Fund will invest generally in longer-term municipal securities, the Common Share NAV and market price per share will fluctuate more in response to changes in market interest

rates than if the Fund invested generally in shorter-term municipal securities. Because the values of lower-rated and comparable unrated debt securities are affected both by credit risk and interest rate risk, the price movements of such lower grade securities typically have not been highly correlated to the fluctuations of the prices of investment grade quality securities in response to changes in market interest rates. The Fund’s use of leverage, as described herein, will tend to increase Common Share interest rate risk.

Municipal Securities Market Risk

Investing in the municipal securities market involves certain risks. The municipal market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the recent market turmoil these firms’ capital was severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal bonds. Historically, the amount of public information available about the municipal securities in the Fund’s portfolio is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of Nuveen Asset Management than if the Fund were a stock fund or taxable bond fund. The secondary market for municipal securities, particularly the below investment grade bonds in which the Fund may invest, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell its municipal securities at attractive prices or at prices approximating those at which the Fund currently values them.

The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal, state and local governments. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability of municipalities to levy taxes. Issuers of municipal securities might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, the Fund could experience delays in collecting principal and interest and the Fund may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Fund may take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Fund’s operating expenses. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt.

Reinvestment Risk

Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the market price of the Common Shares or their overall returns.

Leverage Risk

The use of leverage creates special risks for Common Shareholders, including the likelihood of greater volatility of NAV and market price of, and distributions on, the Common Shares than a comparable portfolio without leverage. The use of leverage in a declining market will likely cause a greater decline in Common Share NAV, which may result in a greater decline of the Common Share price, than if the Fund were not to have used leverage.

leverage or that the Fund’s use of leverage will be successful. Furthermore, the amount of fees paid to NFALLC and Nuveen Asset Management for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets, which may create an incentive for NFALLC to leverage the Fund or increase the Fund’s leverage. Certain types of leverage used by the Fund may result in the Fund being subject to certain covenants, asset coverage or other portfolio composition limits by its lenders, preferred purchasers, rating agencies that may rate the preferred securities, or reverse repurchase counterparties. Such limitations may be more stringent than those imposed by the 1940 Act and may impact whether the Fund is able to maintain its desired amount of leverage. At this time NFALLC does not believe that any such potential investment limitations will impede it from managing the Fund’s portfolio in accordance with its investment objectives and policies. See “Use of Leverage.” The Fund may invest in the securities of other investment companies, which may themselves be leveraged and therefore present similar risks to those described above and magnify the Fund’s leverage risk. The risk of loss attributable to the Fund’s use of leverage is borne by Common Shareholders.

Concentration Risk in California Issuers

The Fund’s policy of investing in municipal securities of issuers located in California makes the Fund more susceptible to the adverse economic, political or regulatory occurrences affecting such issuers. The information set forth below and the related information in Appendix A of this Prospectus is derived from sources that are generally available to investors. The information is intended to give a recent historical description and is not intended to indicate future or continuing trends in the financial or other positions of California. It should be noted that the creditworthiness of obligations issued by local California issuers may be unrelated to the creditworthiness of obligations issued by the State of California, and that there is no obligation on the part of the State to make payment on such local obligations in the event of default.

California is subject to large fluctuations in its tax revenue and fixed spending obligations. During recessionary periods, which California recently experienced, dramatic cuts to programs and/or tax increases may be required. To address budget gaps from the recent recessionary period, spending was cut, State programs were realigned to local governments, and short-term budgetary solutions were implemented. Despite the recent significant budgetary improvements and economic growth, a number of major risks and pressures threaten the State’s financial condition, including the need to repay billions of dollars of obligations that were deferred to balance budgets during the economic downturn. Continued risks to the State’s long-term stability include pension liabilities, the threat of recession, changes in stock prices and changes to federal fiscal policy that are unfavorable to the State.

California’s fiscal situation heightens the risk of investing in bonds issued by the State and its political subdivisions, agencies, instrumentalities and authorities, including the risk of default, and also heightens the risk that the prices of California municipal securities, and the Fund’s NAV, will experience greater volatility. As of April 2018, California general obligation bonds were rated “Aa3” by Moody’s, “AA-” by S&P and “AA-” by Fitch. There can be no assurance that such ratings will be maintained in the future. The State’s credit rating, and any future revisions or withdrawal of a credit rating, could have a negative effect on the market price of the State’s general obligation bonds, as well as notes and bonds issued by California’s public authorities and local governments. Lower credit ratings make it more expensive for the State to raise revenue, and in some cases, could prevent the State from issuing general obligation bonds in the quantity otherwise desired. Further, downgrades can negatively impact the marketability and price of securities in the Fund’s portfolio.

The foregoing information constitutes only a brief summary of some of the general factors that may impact certain issuers of municipal bonds and does not purport to be a complete or exhaustive description of all adverse conditions to which the issuers of municipal bonds held by the Fund are subject. Additionally, many factors, including national economic, social and environmental policies and conditions, which are not within the control of the issuers of the municipal bonds, could affect or could have an adverse impact on the financial condition of the issuers. The Fund is unable to predict whether or to what extent such factors or other factors may affect the issuers of the municipal securities, the market value or marketability of the municipal securities or the ability of

the respective issuers of the municipal bonds acquired by the Fund to pay interest on or principal of the municipal securities. This information has not been independently verified. See Appendix A of this Prospectus for a further discussion of factors affecting municipal securities in California.

Inverse Floating Rate Securities Risk

The Fund may invest in inverse floating rate securities. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a “tender option bond trust”) formed by a third party sponsor for the purpose of holding municipal bonds. See “The Fund’s Investments—Municipal Securities—Inverse Floating Rate Securities.” In general, income on inverse floating rate securities will decrease when interest rates increase and increase when interest rates decrease. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal rates fall. Inverse floating rate securities generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment. Investments in inverse floating rate securities may subject the Fund to the risks of reduced or eliminated interest payments and losses of principal.

The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party sponsor of a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party sponsor of the trust, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. In such instances, the Fund may be at risk of loss that exceeds its investment in the inverse floating rate securities.

Because of the leveraged nature of such investments, inverse floating rate securities may increase or decrease in value at a greater rate than the underlying fixed rate municipal bonds held by the tender option bond. As a result, the market value of such securities generally is more volatile than that of fixed rate securities.

The Fund’s investments in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund may be highly leveraged. The structure and degree to which the Fund’s inverse floating rate securities are highly leveraged will vary based upon a number of factors, including the size of the trust itself and the terms of the underlying municipal security. An inverse floating rate security generally is considered highly leveraged if the principal amount of the short-term floating rate interests issued by the related special purpose trust has a three to one gearing to the principal amount of the inverse floating rate securities owned by the trust. In the event of a significant decline in the value of an underlying security, the Fund may suffer losses in excess of the amount of its investment (up to an amount equal to the value of the municipal securities underlying the inverse floating rate securities) as a result of liquidating special purpose trusts or other collateral required to maintain the Fund’s anticipated effective leverage ratio.

The Fund’s investment in inverse floating rate securities creates effective leverage. Any effective leverage achieved through the Fund’s investment in inverse floating rate securities will create an opportunity for increased Common Share net income and returns, but will also create the possibility that Common Share long-term returns will be diminished if the cost of leverage exceeds the return on the inverse floating rate securities purchased by the Fund.

Inverse floating rate securities have varying degrees of liquidity based, among other things, upon the liquidity of the underlying securities deposited in a special purpose trust. The market price of inverse floating rate securities is more volatile than the underlying securities due to leverage. The leverage attributable to such inverse floating rate securities may be “called away” on relatively short notice and therefore may be less permanent than

more traditional forms of leverage. In certain circumstances, the likelihood of an increase in the volatility of NAV and market price of the Common Shares may be greater for a fund (like the Fund) that relies primarily on inverse floating rate securities to achieve a desired effective leverage ratio. The Fund may be required to sell its inverse floating rate securities at less than favorable prices, or liquidate other Fund portfolio holdings in certain circumstances, including, but not limited to, the following:

•

If the Fund has a need for cash and the securities in a special purpose trust are not actively trading due to adverse market conditions;

•

If special purpose trust sponsors (as a collective group or individually) experience financial hardship and consequently seek to terminate their respective outstanding trusts; and

•

The amount of fees paid to Nuveen Asset Management for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets—this may create an incentive for Nuveen Asset Management to leverage the Fund. “Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage, and derivatives will be valued at their market value.

There is no assurance that the Fund’s strategy of investing in inverse floating rate securities will be successful.

Insurance Risk

The Fund may purchase municipal securities that are secured by insurance, bank credit agreements or escrow accounts. The credit quality of the companies that provide such credit enhancements will affect the value of those securities. Certain significant providers of insurance for municipal securities have recently incurred significant losses as a result of exposure to sub-prime mortgages and other lower credit quality investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. As a result, such losses have reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or the market discounts the value of the insurance provided by the insurer, the rating of the underlying municipal security will be more relevant and the value of the municipal security would more closely, if not entirely, reflect such rating. In such a case, the value of insurance associated with a municipal security would decline and may not add any value. The insurance feature of a municipal security does not guarantee the full payment of principal and interest through the life of an insured obligation, the market value of the insured obligation or the NAV of the Common Shares represented by such insured obligation.

Tax Risk

To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs the Fund must, among other things, derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy a diversification test on a quarterly basis. If the Fund fails to satisfy the qualifying income or diversification requirements in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. In order to be eligible for the relief provisions with respect to a failure to meet the diversification requirements, the Fund may be required to dispose of certain assets. If these relief provisions were not available to the Fund and it were to fail to qualify for

treatment as a RIC for a taxable year, all of its taxable income (including its net capital gain) would be subject to tax at regular corporate rates (which the Tax Act reduced to 21%) without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

Taxability Risk

The Fund invests in municipal securities in reliance at the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable from gross income for federal income tax purposes, and Nuveen Asset Management will not independently verify that opinion. Subsequent to the Fund’s acquisition of such a municipal security, however, the security may be determined to pay, or to have paid, taxable income. As a result, the treatment of dividends previously paid or to be paid by the Fund as “exempt-interest dividends” could be adversely affected, subjecting the Fund’s shareholders to increased federal income tax liabilities.

Distributions of ordinary taxable income (including any net short-term capital gain) will be taxable to shareholders as ordinary income (and not eligible for favorable taxation as “qualified dividend income”), and capital gain dividends will be taxable as long-term capital gains. See “Tax Matters.”

Borrowing Risks

In addition to borrowing for leverage (See “Use of Leverage”), the Fund may borrow for temporary or emergency purposes, including to meet redemption requests, pay dividends, repurchase its shares, or clear portfolio transactions. Borrowing may exaggerate changes in the NAV of the Fund’s shares and may affect the Fund’s net income. When the Fund borrows money, it must pay interest and other fees, which will reduce the fund’s returns if such costs exceed the returns on the portfolio securities purchased or retained with such borrowings. Any such borrowings are intended to be temporary. However, under certain market conditions, including periods of low demand or decreased liquidity in the municipal bond market such borrowings might be outstanding for longer periods of time.

Inflation Risk

Inflation risk is the risk that the value of assets or income from investment will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the dividends paid to preferred shareholders can decline, and the real value of Common Shares and the distributions can decline. In addition,

during any period of rising inflation, interest rates on borrowings would likely increase, which would tend to further reduce returns to Common Shareholders.

Sector and Industry Risk

The Fund may not invest more than 25% of its total assets in municipal securities in any one industry, provided, however, that such limitation shall not apply to municipal bonds other than those municipal bonds backed only by the assets and revenues of non-governmental users. The Fund’s 25% industry limitation will apply to tax-exempt municipal securities if the payment of principal and interest for such securities is derived principally from a specific project associated with an issuer that is not a governmental entity or a political subdivision of a government, and in that situation, the Fund will consider such municipal securities to be in an industry associated with the project. In addition, subject to the concentration limits of the Fund’s investment policies and guidelines, the Fund may invest a significant portion of its net assets in certain sectors of the municipal securities market, such as hospitals and other health care facilities, charter schools and other private educational facilities, special taxing districts and start-up utility districts, and private activity bonds including industrial development bonds on behalf of transportation companies such as airline companies, whose credit quality and performance may be more susceptible to economic, business, political, regulatory and other developments than other sectors of municipal issuers. If the Fund invests a significant portion of its net assets in the sectors noted above, the Fund’s performance may be subject to additional risk and variability. To the extent that the Fund focuses its net assets in the hospital and healthcare facilities sector, for example, the Fund will be subject to risks associated with such sector, including adverse government regulation and reduction in reimbursement rates, as well as government approval of products and services and intense competition. Securities issued with respect to special taxing districts will be subject to various risks, including real-estate development related risks and taxpayer concentration risk. Further, the fees, special taxes or tax allocations and other revenues established to secure the obligations of securities issued with respect to special taxing districts are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. Charter schools and other private educational facilities are subject to various risks, including the reversal of legislation authorizing or funding charter schools, the failure to renew or secure a charter, the failure of a funding entity to appropriate necessary funds and competition from alternatives such as voucher programs. Issuers of municipal utility securities can be significantly affected by government regulation, financing difficulties, supply and demand of services or fuel and natural resource conservation. The transportation sector, including airports, airlines, ports and other transportation facilities, can be significantly affected by changes in the economy, fuel prices, labor relations, insurance costs and government regulation.

Special Risks Related to Certain Municipal Obligations

The Fund may invest in municipal leases and certificates of participation in such leases. Municipal leases and certificates of participation involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover the Fund’s original investment. In the event of non-appropriation, the issuer would be in default and taking ownership of the assets may be a remedy

available to the Fund, although the Fund does not anticipate that such a remedy would normally be pursued. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. Certificates of participation, which represent interests in unmanaged pools of municipal leases or installment contracts, involve the same risks as the underlying municipal leases. In addition, the Fund may be dependent upon the municipal authority issuing the certificates of participation to exercise remedies with respect to the underlying securities. Certificates of participation also entail a risk of default or bankruptcy, both of the issuer of the municipal lease and also the municipal agency issuing the certificate of participation.

The Fund may invest in tobacco settlement bonds. Tobacco settlement bonds are municipal securities that are backed solely by expected revenues to be derived from lawsuits involving tobacco related deaths and illnesses which were settled between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state’s proportionate share in the Master Settlement Agreement (“MSA”). The MSA is an agreement, reached out of court in November 1998 between 46 states and nearly all of the U.S. tobacco manufacturers. Under the terms of the MSA, the actual amount of future settlement payments by tobacco-manufacturers is dependent on many factors, including, but not limited to, annual domestic cigarette shipments, reduced cigarette consumption, increased taxes on cigarettes, inflation, financial capability of tobacco companies, continuing litigation and the possibility of tobacco manufacturer bankruptcy. Payments made by tobacco manufacturers could be negatively impacted if the decrease in tobacco consumption is significantly greater than the forecasted decline.

Derivatives Risk, Including the Risk of Swaps

The Fund’s use of derivatives involves risks different from, and possibly greater than, the risks associated with investing directly in the investments underlying the derivatives. Whether the Fund’s use of derivatives is successful will depend on, among other things, if NFALLC and Nuveen Asset Management correctly forecasts market values, interest rates and other applicable factors. If NFALLC and Nuveen Asset Management incorrectly forecasts these and other factors, the investment performance of the Fund will be unfavorably affected. In addition, the derivatives market is largely unregulated. It is possible that developments in the derivatives market could adversely affect the Fund’s ability to successfully use derivative instruments.

The Fund may enter into debt-related derivatives instruments including credit swap default contracts and interest rate swaps. Like most derivative instruments, the use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In addition, the use of swaps requires an understanding by Nuveen Asset Management not only of the referenced asset, rate or index, but also of the swap itself. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. It is possible that developments in the swaps market, including potential government regulation, could adversely affect the Fund’s ability to terminate existing swap agreements or to realize amounts to be received under such agreements. The derivatives market is subject to a changing regulatory environment. It is possible that regulatory or other developments in the derivatives market could adversely affect the Fund’s ability to successfully use derivative instruments. See also, “Risk Factors—Counterparty Risk,” “Risk Factors—Hedging Risk” and the SAI.

Counterparty Risk

Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to derivatives, insured municipal securities or other transactions supported by another party’s credit will affect the value of those instruments. Certain entities that have served as counterparties in the markets for these transactions have recently incurred significant financial hardships including bankruptcy and losses as a result of

exposure to sub-prime mortgages and other lower quality credit investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. As a result, such hardships have reduced these entities’ capital and called into question their continued ability to perform their obligations under such transactions. By using such derivatives or other transactions, the Fund assumes the risk that its counterparties could experience similar financial hardships.

Hedging Risk

The Fund’s use of derivatives or other transactions to reduce risk involves costs and will be subject to NFALLC and Nuveen Asset Management’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that NFALLC and Nuveen Asset Management’s judgment in this respect will be correct. In addition, no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so.

Deflation Risk

Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.

Illiquid Securities Risk

The Fund may invest in municipal securities and other instruments that, at the time of investment, are illiquid. Illiquid securities are securities that are not readily marketable and may include some restricted securities, which are securities that may not be resold to the public without an effective registration statement under the 1933 Act, if they are unregistered, may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. Illiquid securities involve the risk that the securities will not be able to be sold at the time desired by the Fund or at prices approximating the value at which the Fund is carrying the securities on its books.

Call Risk

If interest rates fall, it is possible that issuers of callable bonds with higher interest coupons will “call” (or prepay) their bonds before their maturity date. If a call were exercised by the issuer during a period of declining interest rates, the Fund is likely to replace such called security with a lower yielding security.

Potential Conflicts of Interest Risk

NFALLC and Nuveen Asset Management each provide a wide array of portfolio management and other asset management services to a mix of clients and may engage in ordinary course activities in which their respective interests or those of their clients may compete or conflict with those of the Fund. For example, NFALLC and Nuveen Asset Management may provide investment management services to other funds and accounts that follow investment objectives similar to those of the Fund. In certain circumstances, and subject to its fiduciary obligations under the Investment Advisers Act of 1940, Nuveen Asset Management may have to allocate a limited investment opportunity among its clients, which include closed-end funds, open-end funds and other commingled funds. NFALLC and Nuveen Asset Management have each adopted policies and procedures designed to address such situations and other potential conflicts of interests. For additional information about potential conflicts of interest, and the way in which NFALLC and Nuveen Asset Management address such conflicts, please see the SAI.

Impact of Offering Methods Risk

The issuance of Common Shares through the various methods described in this Prospectus may have an adverse effect on prices in the secondary market for the Fund’s Common Shares by increasing the number of Common Shares available for sale. In addition, Common Shares may be issued at a discount to the market price for such Common Shares, which may put downward pressure on the market price for Common Shares of the Fund.

Cybersecurity Risk

Technology, such as the internet, has become more prevalent in the course of business, and as such, the Fund and its service providers are susceptible to operational and information security risk resulting from cyber incidents. Cyber incidents refer to both intentional attacks and unintentional events including: processing errors, human errors, technical errors including computer glitches and system malfunctions, inadequate or failed internal or external processes, market-wide technical-related disruptions, unauthorized access to digital systems (through “hacking” or malicious software coding), computer viruses, and cyber-attacks which shut down, disable, slow or otherwise disrupt operations, business processes or website access or functionality (including denial of service attacks). Cyber incidents could adversely impact the Fund and cause the Fund to incur financial loss and expense, as well as face exposure to regulatory penalties, reputational damage, and additional compliance costs associated with corrective measures. Cyber incidents may cause the Fund or its service providers to lose proprietary information, suffer data corruption, lose operational capacity or fail to comply with applicable privacy and other laws. Among other potentially harmful effects, cyber incidents also may result in theft, unauthorized monitoring and failures in the physical infrastructure or operating systems that support the Fund and its service providers. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. While the Fund’s service providers have established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund.

Certain Affiliations

Certain broker-dealers may be considered to be affiliated persons of the Fund, NFALLC, Nuveen Asset Management and/or, Nuveen Investments. Absent an exemption from the SEC or other regulatory relief, the Fund is generally precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. The Fund has not applied for and does not intend to apply for such relief. This could limit the Fund’s ability to engage in securities transactions, purchase certain adjustable rate senior loans, if applicable, and take advantage of market opportunities. In addition, in the event shares are sold through a syndicated offering, unless and until the underwriting syndicate is broken in connection with the public offering of the Common Shares, the Fund will be precluded from effecting principal transactions with brokers who are members of the syndicate.

Anti-Takeover Provisions

The Fund’s Declaration and By-Laws include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status. These provisions could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares. See “Certain Provisions in the Declaration of Trust.”

Other Investment Companies Risk

The Fund may invest in the securities of other investment companies. Such securities may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities. Utilization of

leverage is a speculative investment technique and involves certain risks. An investment in securities of other investment companies that are leveraged may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund’s long-term returns on such securities (and, indirectly, the long-term returns of the Common Shares) will be diminished.

Financial Futures and Options Transactions Risk

The Fund may use certain transactions for hedging the portfolio’s exposure to high yield credit risk and the risk of increases in interest rates, which could result in poorer overall performance for the Fund. The Fund’s use of certain transactions to reduce risk involves costs and will be subject to Nuveen Asset Management’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that Nuveen Asset Management’s judgment in this respect will be correct. In addition, no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so.

There are certain risks associated with the use of financial futures and options to hedge investment portfolios. There may be an imperfect correlation between price movements of the futures and options and price movements of the portfolio securities being hedged. Losses may be incurred in hedging transactions, which could reduce the portfolio gains that might have been realized if the hedging transactions had not been entered into. If the Fund engages in futures transactions or in the writing of options on futures, it will be required to maintain initial margin and maintenance margin and may be required to make daily variation margin payments in accordance with applicable rules of the exchanges and the CFTC. If the Fund purchases a financial futures contract or a call option or writes a put option in order to hedge the anticipated purchase of municipal securities, and if the Fund fails to complete the anticipated purchase transaction, the Fund may have a loss or a gain on the futures or options transaction that will not be offset by price movements in the municipal securities that were the subject of the anticipatory hedge. The cost of put options on debt securities or indexes effectively increases the cost of the securities subject to them, thereby reducing the yield otherwise available from these securities. If the Fund decides to use futures contracts or options on futures contracts for hedging purposes, the Fund will be required to establish an account for such purposes with one or more CFTC-registered futures commission merchants. A futures commission merchant could establish initial and maintenance margin requirements for the Fund that are greater than those which would otherwise apply to the Fund under applicable rules of the exchanges and the CFTC. There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a derivatives or futures or a futures option position, and the Fund would remain obligated to meet margin requirements until the position is closed. Futures exchanges may limit the amount of fluctuation permitted in certain futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of the current trading session. Once the daily limit has been reached in a futures contract subject to the limit, no more trades may be made on that day at a price beyond that limit. The daily limit governs only price movements during a particular trading day and therefore does not limit potential losses because the limit may work to prevent the liquidation of unfavorable positions. For example, futures prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of positions and subjecting some holders of futures contracts to substantial losses.

Risks Related to the Fund’s Clearing Broker and Central Clearing Counterparty

The Commodity Exchange Act (“CEA”) requires swaps and futures clearing brokers registered as “futures commission merchants” to segregate all funds received from customers with respect to any orders for the purchase or sale of U.S. domestic futures contracts and cleared swaps from the brokers’ proprietary assets. Similarly, the CEA requires each futures commission merchant to hold in separate secure accounts all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and cleared swaps and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by a clearing broker from its customers are held by the clearing

broker on a commingled basis in an omnibus account and may be invested in certain instruments permitted under applicable regulations. There is a risk that assets deposited by the Fund with any swaps or futures clearing broker as margin for futures contracts or cleared swaps may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing broker. In addition, the assets of the Fund might not be fully protected in the event of the Fund’s clearing broker’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker’s customers for the relevant account class. Similarly, the CEA requires a clearing organization approved by the CFTC as a derivatives clearing organization to segregate all funds and other property received from a clearing member’s clients in connection with domestic cleared derivative contracts from any funds held at the clearing organization to support the clearing member’s proprietary trading. Nevertheless, all customer funds held at a clearing organization in connection with any futures contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. All customer funds held at a clearing organization with respect to cleared swaps of customers of a clearing broker are also held in an omnibus account, but CFTC rules require that the clearing broker notify the clearing organization of the amount of the initial margin provided by the clearing broker to the clearing organization that is attributable to each customer. With respect to futures and options contracts, a clearing organization may use assets of a nondefaulting customer held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. With respect to cleared swaps, a clearing organization generally cannot do so, but may do so if the clearing member does not provide accurate reporting to the clearing organization as to the attribution of margin among its clients. Also, since clearing brokers generally provide to clearing organizations the net amount of variation margin required for cleared swaps for all of its customers in the aggregate, rather than the gross amount of each customer, the Fund is subject to the risk that a clearing organization will not make variation margin payments owed to the Fund if another customer of the clearing member has suffered a loss and is in default. As a result, in the event of a default or the clearing broker’s other clients or the clearing broker’s failure to extend its own funds in connection with any such default, the Fund may not be able to recover the full amount of assets deposited by the clearing broker on behalf of the Fund with the clearing organization.

Prepayment Risk

During periods of declining interest rates or for other purposes, issuers may experience their option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding instruments. For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be increased.

MANAGEMENT OF THE FUND

Trustees and Officers

The Board is responsible for the management of the Fund, including supervision of the duties performed by NFALLC and Nuveen Asset Management. The names and business addresses of the trustees and officers of the Fund and their principal occupations and other affiliations during the past five years are set forth under “Management of the Fund” in the SAI.

Investment Management and Sub-Advisory Agreements

Investment Management Agreement. Pursuant to an investment management agreement between NFALLC and the Fund (the “Investment Management Agreement”), the Fund has agreed to pay an annual management fee for the services and facilities provided by NFALLC, payable on a monthly basis, based on the sum of a fund-level fee and a complex-level fee, as described below.

Fund-Level Fee. The annual fund-level fee for the Fund, payable monthly, is calculated according to the following schedule:


Average Daily Managed Assets*	Fund-Level Fee Rate
For the first $125 million		0.4500	%
For the next $125 million		0.4375	%
For the next $250 million		0.4250	%
For the next $500 million		0.4125	%
For the next $1 billion		0.4000	%
For the next $3 billion		0.3750	%
For Managed Assets over $5 billion		0.3625	%

Complex-Level Fee. The annual complex-level fee for the Fund, payable monthly, is calculated by multiplying the current complex-wide fee rate, determined according to the following schedule, by the Fund’s daily managed assets:


Complex-Level Eligible Asset Breakpoint Level*	Effective Complex-Level Fee Rate at Breakpoint Level
$55 billion		0.2000	%
$56 billion		0.1996	%
$57 billion		0.1989	%
$60 billion		0.1961	%
$63 billion		0.1931	%
$66 billion		0.1900	%
$71 billion		0.1851	%
$76 billion		0.1806	%
$80 billion		0.1773	%
$91 billion		0.1691	%
$125 billion		0.1599	%
$200 billion		0.1505	%
$250 billion		0.1469	%
$300 billion		0.1445	%

For the complex-level fees, managed assets include closed-end fund assets managed by NFALLC that are attributable to certain types of leverage. For these purposes, leverage includes the funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by NFALLC as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen open-end and closed-end funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen funds or assets in excess of a determined amount (originally $2 billion) added to the Nuveen fund complex in connection with NFALLC’s assumption of the management of the former First American Funds effective January 1, 2011. As of February 28, 2018, the complex-level fee rate for the Fund was 0.1595%.

In addition to the fee of NFALLC, the Fund pays all other costs and expenses of its operations, including compensation of its trustees (other than those affiliated with NFALLC and Nuveen Asset Management), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses associated with any Borrowings, expenses of issuing any Preferred Shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies, and taxes, if any. All fees and expenses are accrued daily and deducted before payment of dividends to investors.

A discussion regarding the basis for the Board’s decision to approve the Investment Management Agreement for the Fund may be found in the Fund’s semi-annual report to shareholders for the period ended August 31 of each year.

Sub-Advisory Agreement. Pursuant to the Sub-Advisory Agreement, Nuveen Asset Management will receive from NFALLC a management fee equal to 38.4620% of NFALLC’s net management fee from the Fund. NFALLC and Nuveen Asset Management retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

NET ASSET VALUE

The Fund’s NAV per share is determined as of the close of regular session trading (normally 4:00 p.m., Eastern Time) on each day the NYSE is open for business. NAV is calculated by taking the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of shares outstanding. The result, rounded to the nearest cent, is the NAV per share. All valuations are subject to review by the Fund’s Board or its delegate.

In determining NAV, expenses are accrued and applied daily and securities and other assets for which market quotations are available are valued at market value. The prices of municipal bonds are provided by a pricing service approved by the Fund’s Board. When market price quotes are not readily available (which is usually the case for municipal securities), the pricing service, or, in the absence of a pricing service for a particular security, the Board of the Fund, or its designee, may establish fair market value using a wide variety of market data including yields or prices of municipal bonds of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from securities dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant by the pricing service or the Board’s designee. Exchange-listed securities are generally valued at the last sales price on the securities exchange on which such securities are primarily traded. Securities traded on a securities exchange for which there are no transactions on a given day or securities not listed on a securities exchange are valued at the closing bid prices. Securities traded on Nasdaq are valued at the Nasdaq Official Closing Price. Temporary investments in securities that have variable rate and demand features qualifying them as short-term investments are valued at amortized cost, which approximates market value. See “Net Asset Value” in the SAI for more information.

The valuations for fixed income securities and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of fair valuation techniques and methodologies. Short-term fixed income securities that will mature in 60 days or less are valued at amortized cost, unless it is determined that using this method would not reflect an investment’s fair value.

The valuations of certain fixed income securities will generally be based on prices determined as of the earlier closing time of the markets on which they primarily trade, unless a significant event has occurred.

If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed to be unreliable, the market price may be determined by using quotations from one or more broker/dealers. When such prices or quotations are not available, or when believed to be unreliable, securities may be priced using fair value procedures approved by the Board. These procedures permit, among other things, the use of a matrix, formula or other method that takes into consideration market indexes, yield curves and other specific adjustments to determine fair value. The Fund may also use fair value procedures if it is determined that a significant event has occurred between the time at which a market price is determined and the time at which the fund’s NAV is calculated. The effect of using fair value pricing is that the Common Share NAV will be subject to the judgment of the Board or its designee instead of being determined by the market. See “Net Asset Value” in the SAI for more information.

DISTRIBUTIONS

The Fund pays regular monthly distributions to Common Shareholders at a level rate (stated in terms of a fixed cents per Common Shares dividend rate) that reflects the past and projected performance of the Fund.

Distributions can only be made from net investment income after paying any accrued dividends to preferred shareholders, if additional preferred shares are issued in the future, or interest and required principal payments on borrowings.

The Fund’s ability to maintain a level dividend rate will depend on a number of factors, including the rate at which dividends are payable on the Preferred Shares. The net income of the Fund includes all interest income accrued on portfolio assets less all expenses of the Fund. Expenses of the Fund are accrued each day. For each year, all or substantially all of the net investment income of the Fund will be distributed. At least annually, the Fund also intends to distribute substantially all of its net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) and ordinary taxable income, if any, after paying any accrued dividends or making any liquidation payments to preferred shareholders and any interest and required principal payments on borrowings. Although it does not now intend to do so, the Board may change the Fund’s dividend policy and the amount or timing of the distributions, based on a number of factors, including the amount of the Fund’s undistributed net investment income and historical and projected investment income and the amount of the expenses and dividend rates on outstanding Preferred Shares and expenses and interest on borrowings.

The Fund might not distribute all or a portion of any net capital gain for a taxable year. If the Fund does not distribute all of its net capital gain for a taxable year, it will pay federal income tax on the retained gain. Each Common Shareholder of record as of the end of the Fund’s taxable year (i) will include in income for federal income tax purposes, as long-term capital gain, his or her share of the retained gain, (ii) will be deemed to have paid his or her proportionate share of tax paid by the Fund on such retained gain, and (iii) will be entitled to an income tax credit or refund for that share of the tax. While not currently anticipated, if the Fund makes total distributions for a taxable year in an amount that exceeds the Fund’s earnings and profits, the excess would generally be treated by Common Shareholders as a return of capital for tax purposes. A return of capital reduces a shareholder’s tax basis, which could result in higher taxes when the shareholder sells his or her shares. This may cause the shareholder to pay taxes even if he or she sells shares for less than the original price.

The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time, subject to a finding by the Fund’s Board that such change is in the best interests of the Fund and its Common Shareholders, and may do so without prior notice to Common Shareholders.

DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund’s Dividend Reinvestment Plan (the “Plan”), you may elect to have all dividends, including any capital gain dividends, on your Common Shares automatically reinvested by the Plan Agent (defined below) in additional Common Shares under the Plan. You may elect to participate in the Plan by contacting Nuveen Investors Services at (800) 257-8787. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you or your brokerage firm by Computershare Trust Company, N.A. and Computershare Inc., collectively (“Computershare”), as dividend paying agent (the “Plan Agent”). The tax consequences of a distribution are the same regardless of whether such distribution is reinvested or received in cash. See “Tax Matters” below.

If you decide to participate in the Plan, the number of Common Shares you will receive will be determined as follows:

(1) If Common Shares are trading at or above NAV at the time of valuation, the Fund will issue new shares at the then current market price;

(2) If Common Shares are trading below NAV at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the NYSE or

elsewhere, for the participants’ accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date. Interest will not be paid on any uninvested cash payments; or

(3) If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below NAV, but the Fund’s shares subsequently trade at or above their NAV before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares’ NAV or 95% of the shares’ market value.

You may withdraw from the Plan at any time by giving written notice to the Plan Agent. If you withdraw or the Plan is terminated, you will receive whole shares in your account under the Plan and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions and a $2.50 service fee.

The Plan Agent maintains all shareholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Upon a repurchase of your shares, the Fund (or its administrative agent) may be required to report to the IRS and furnish to you cost basis and holding period information for the Fund’s shares purchased on or after January 1, 2012 (“covered shares”).

For shares of the Fund held in the Plan, you are permitted to elect from among several permitted cost basis methods. In the absence of an election, the Plan will use first-in first-out (“FIFO”) methodology for tracking and reporting your cost basis on covered shares as its default cost basis method. The cost basis method you use may not be changed with respect to a repurchase of shares after the settlement date of the repurchase. You should consult with your tax advisors to determine the best permitted cost basis method for your tax situation and to obtain more information about how the new cost basis reporting rules apply to you. Shareholders should also carefully review any cost basis information provided to them and make any additional basis, holding period or other adjustments that are required when reporting these amounts on their federal income tax returns.

Common Shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due, if any, upon receiving dividends and distributions.

If you hold your Common Shares with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above. Consult your financial advisor for more information.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained by writing to ComputerShare, P.O. Box 505000, Louisville, Kentucky, 40233-5000, (800) 257-8787.

PLAN OF DISTRIBUTION

The Fund may sell the Common Shares offered under this Prospectus through

•

at-the-market transactions;

•

underwriting syndicates; and

•

privately negotiated transactions.

The Fund will bear the expenses of the offering, including but not limited to, the expenses of preparation of the Prospectus and SAI for the offering and the expense of counsel and auditors in connection with the offering.

Distribution Through At-the-Market Transactions

The Fund has entered into a distribution agreement with Nuveen Securities (the “Distribution Agreement”), which has been filed as an exhibit to the Registration Statement of which this Prospectus is a part. Subject to the terms and conditions of the Distribution Agreement, the Fund may from time to time issue and sell its Common Shares through Nuveen Securities to certain broker-dealers which have entered into selected dealer agreements with Nuveen Securities. Currently, Nuveen Securities has entered into a selected dealer agreement (the “Selected Dealer Agreement”) with UBS Securities, LLC (“UBS”) pursuant to which UBS acts as Nuveen Securities’ sub-placement agent with respect to at-the-market offerings of Common Shares. The Selected Dealer Agreement has been filed as an exhibit to the Registration Statement of which this Prospectus forms a part. Subject to the terms and conditions of the Distribution Agreement, the Fund may from time to time issue and sell its Common Shares through Nuveen Securities to certain broker-dealers which have entered into selected dealer agreements with Nuveen Securities.

Common Shares will only be sold on such days as shall be agreed to by the Fund and Nuveen Securities. Common Shares will be sold at prevailing market prices through the National Market System, subject to a minimum price to be established each day by Nuveen Securities. The minimum price on any day will not be less than the current NAV per Common Share plus the per share amount of the commission to be paid to Nuveen Securities. The Fund, Nuveen Securities and UBS will suspend the sale of Common Shares if the per share price of the shares is less than the minimum price.

The Fund will compensate Nuveen Securities with respect to sales of the Common Shares at a fixed commission rate of up to 1.0% of the gross proceeds of the sale of Common Shares. Nuveen Securities will compensate sub-placement agents or other broker-dealers participating in the offering at a rate of up to 0.8% of the gross proceeds of the sale of Common Shares sold by that sub-placement agent or broker-dealer. Settlements of sales of Common Shares will occur on the third business day following the date on which any such sales are made. In connection with the sale of the Common Shares on behalf of the Fund, Nuveen Securities may be deemed to be an underwriter within the meaning of the 1933 Act, and the compensation of Nuveen Securities may be deemed to be underwriting commissions or discounts. Unless otherwise indicated in a further Prospectus supplement, Nuveen Securities will act as underwriter on a reasonable efforts basis.

The offering of Common Shares pursuant to the Distribution Agreement will terminate upon the earlier of (i) the sale of all Common Shares subject thereto or (ii) termination of the Distribution Agreement. The Fund and Nuveen Securities each have the right to terminate the Distribution Agreement in its discretion at any time. The Fund currently intends to distribute the shares offered pursuant to this Prospectus primarily through at-the-market transactions, although from time to time it may also distribute shares through an underwriting syndicate or a privately negotiated transaction. To the extent shares are distributed other than through at-the-market transactions, the Fund will file a supplement to this Prospectus describing such transactions.

The Fund’s closing price on the NYSE on April 26, 2018 was $13.32.

Distribution Through Underwriting Syndicates

The Fund from time to time may issue additional Common Shares through a syndicated secondary offering. In order to limit the impact on the market price of the Fund’s Common Shares, underwriters will market and price the offering on an expedited basis (e.g., overnight or similarly abbreviated offering period). The Fund will launch a syndicated offering on a day, and upon terms, mutually agreed upon between the Fund, Nuveen Securities, one of the Fund’s underwriters, and the underwriting syndicate.

The Fund will offer its shares at a price equal to a specified discount of up to 5% from the closing market price of the Fund’s Common Shares on the day prior to the offering date. The applicable discount will be negotiated by the Fund and Nuveen Securities in consultation with the underwriting syndicate on a transaction-by-transaction basis. The Fund will compensate the underwriting syndicate out of the proceeds of the offering based upon a sales load of up to 4% of the gross proceeds of the sale of Common Shares. The minimum net proceeds per share to the Fund will not be less than the greater of (i) the Fund’s latest net asset value per Common Share or (ii) 91% of the closing market price of the shares of the Fund’s Common Shares on the day prior to the offering date.

Distribution Through Privately Negotiated Transactions

The Fund from time to time may sell directly to, and solicit offers from, institutional and other sophisticated investors, who may be deemed to be underwriters as defined in the 1933 Act for any resale of Common Shares. No sales commission or other compensation will be paid to Nuveen Securities or any other FINRA member in connection with such transactions.

Common Shares issued by the Fund through privately negotiated transactions will be issued at a price equal to the greater of (i) the net asset value per share of the Fund’s Common Shares or (ii) at a discount ranging from 0% to 5% of the average daily closing market price of the Fund’s Common Shares at the close of business on the 0% to 5% of the average daily closing market price of the Fund’s Common Shares at the close of business on the two business days preceding the date upon which Common Shares are sold pursuant to the privately negotiated transaction. The applicable discount will be determined by the Fund on a transaction-by-transaction basis.

The principal business address of Nuveen Securities is 333 West Wacker Drive, Suite 3300, Chicago, Illinois 60606.

DESCRIPTION OF SHARES

Common Shares

The Declaration authorizes the issuance of an unlimited number of Common Shares. The Common Shares being offered have a par value of $0.01 per share and, subject to the rights of holders of preferred shares, if issued, and borrowings, if incurred have equal rights to the payment of dividends and the distribution of assets upon liquidation of the Fund. The Common Shares being offered will, when issued, be fully paid and, subject to matters discussed under “Certain Provisions in the Declaration of Trust,” non-assessable, and will have no pre-emptive or conversion rights or rights to cumulative voting. Each Common Share has one vote with respect to matters upon which a shareholder vote is required, consistent with the requirements of the 1940 Act and the

rules promulgated thereunder, and will vote together as a single class. Whenever the Fund incurs borrowings and/or preferred shares are outstanding, Common Shareholders will not be entitled to receive any cash distributions from the Fund unless all interest on such borrowings has been paid and all accrued dividends on preferred shares have been paid, unless asset coverage (as defined in the 1940 Act) with respect to any borrowings would be at least 300% after giving effect to the distributions and asset coverage (as defined in the 1940 Act) with respect to preferred shares would be at least 200% after giving effect to the distributions. See “Preferred Shares” below.

The Common Shares are listed on the NYSE and trade under the ticker symbol “NKX.” The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing. The Fund will not issue share certificates.

Unlike open-end funds, closed-end funds like the Fund do not provide daily redemptions. Rather, if a shareholder determines to buy additional Common Shares or sell shares already held, the shareholder may conveniently do so by trading on the exchange through a broker or otherwise. Shares of closed-end investment companies may frequently trade on an exchange at prices lower than NAV. Shares of closed-end investment companies like the Fund have during some periods traded at prices higher than NAV and have during other periods traded at prices lower than NAV.

Because the market value of the Common Shares may be influenced by such factors as dividend levels (which are in turn affected by expenses), call protection, dividend stability, portfolio credit quality, NAV, relative demand for and supply of such shares in the market, general market and economic conditions, and other factors beyond the control of the Fund, the Fund cannot guarantee you that Common Shares will trade at a price equal to or higher than NAV in the future. The Common Shares are designed primarily for long-term investors, and investors in the Common Shares should not view the Fund as a vehicle for trading purposes.

Preferred Shares

The Declaration authorizes the issuance of an unlimited number of Preferred Shares in one or more classes or series, with rights as determined by the Board without the approval of holders of Common Shares. The Executive Committee of the Board, acting pursuant to authority delegated to it by the full Board, has authorized and the Fund has outstanding 2,922 VRDP Shares and 1,404 MFP Shares, as of March 31, 2018. The decision to issue additional Preferred Shares is subject to market conditions and to the Board’s belief that leveraging the Fund’s capital structure through the issuance of Preferred Shares is likely to achieve the benefits to the Common Shareholders described in the Prospectus.

Under the 1940 Act, the Fund is not permitted to issue “senior securities” that are Preferred Shares if, immediately after the issuance of Preferred Shares, the asset coverage ratio with respect to such shares would be less than 200%. See “Leverage.” Additionally, the Fund will generally not be permitted to purchase any of its Common Shares or declare dividends (except a dividend payable in Common Shares) or other distributions on its Common Shares unless, at the time of such purchase or declaration, the asset coverage ratio with respect to such Preferred Shares, after taking into account such purchase or distribution, is at least 200%.

Distribution Preference. Preferred Shares have complete priority over Common Shares as to distribution of assets.

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Fund, holders of Preferred Shares would be entitled to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus accumulated and unpaid dividends thereon, whether or not earned or declared) before any distribution of assets is made to Common Shareholders.

Voting Rights. Preferred Shares are required to be voting shares and to have equal voting rights with Common Shares. Except as otherwise indicated in this Prospectus or the SAI and except as otherwise required by applicable law, Preferred Shares would vote together with Common Shareholders as a single class.

Holders of Preferred Shares voting as a separate class, will be entitled to elect two of the Fund’s trustees (following the establishment of the Fund by an initial trustee, the Declaration provides for a total of no less than two and no more than 12 trustees). The remaining trustees will be elected by Common Shareholders and holders of preferred shares, voting together as a single class. In the unlikely event that two full years of accrued dividends are unpaid on the Preferred Shares, the holders of all outstanding Preferred Shares voting as a separate class, will be entitled to elect a majority of the Fund’s trustees until all dividends in arrears have been paid or declared and set apart for payment. In order for the Fund to take certain actions or enter into certain transactions, a separate class vote of holders of Preferred Shares would be required, in addition to the single class vote of the holders of Preferred Shares and Common Shares. See “Certain Provisions in the Declaration of Trust” and the SAI under “Description of Shares—Preferred Shares—Voting Rights.”

Redemption, Purchase and Sale of Preferred Shares. The terms of any Preferred Share offering provide that they may be redeemed by the issuer at certain times, in whole or in part, at the original purchase price per share plus accumulated dividends. Any redemption or purchase of Preferred Shares by the Fund will reduce the leverage applicable to Common Shares, while any issuance of shares by the Fund would increase such leverage.

The Fund applied for and obtained ratings for its Preferred Shares from two NRSROs. As long as Preferred Shares are outstanding, the composition of the Fund’s portfolio would reflect guidelines established by such NRSROs. Based on previous guidelines established by such NRSROs for the securities of other issuers, the Fund anticipates that the guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. However, at this time, no assurance can be given as to the nature or extent of the guidelines that may be imposed in connection with obtaining a rating of any Preferred Shares.

CERTAIN PROVISIONS IN THE DECLARATION OF TRUST AND BY-LAWS

Shareholder and Trustee Liability. Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Fund. However, the Declaration contains an express disclaimer of shareholder liability for debts or obligations of the Fund and requires that notice of such limited liability be given in each agreement, obligation or instrument entered into or executed by the Fund or the trustees. The Declaration further provides for indemnification out of the assets and property of the Fund for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund would be unable to meet its obligations. The Fund believes that the likelihood of such circumstances is remote.

The Declaration provides that the Fund’s obligations are not binding upon the Fund’s trustees individually, but only upon the Fund’s assets and property, and that the trustees shall not be liable for errors of judgment or mistakes of fact or law. Nothing in the Declaration, however, protects a trustee against any liability to which he or she would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

Anti-Takeover Provisions. The Declaration and By-Laws include provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. The By-Laws require the Board be divided into three classes with staggered terms. See the SAI under “Management of the Fund.” This provision of the By-Laws could delay for up to two years the replacement of a majority of the Board. If preferred shares are issued, holders of preferred shares, voting as a separate class, will be entitled to elect two of the Fund’s trustees. In addition, the Declaration includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. Specifically, the Declaration requires a vote by holders of at least two-thirds of the Common Shares and Preferred Shares voting together as a single class, except as described below, to authorize (1) a conversion of the Fund from a closed-end to an

open-end investment company, (2) a merger or consolidation of the Fund, or a series or class of the Fund, with any corporation, association, trust or other organization or a reorganization of the Fund, or a series or class of the Fund, (3) a sale, lease or transfer of all or substantially all of the Fund’s assets (other than in the regular course of the Fund’s investment activities), (4) in certain circumstances, a termination of the Fund, or a series or class of the Fund or (5) removal of trustees by shareholders (except at the end of a trustee’s term), and then only for cause, unless, with respect to (1) through (4), such transaction has already been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-Laws, in which case the affirmative vote of the holders of at least a majority of the Fund’s Common Shares and Preferred Shares outstanding at the time, voting together as a single class, is required, provided, however, that where only a particular class or series is affected (or, in the case of removing a trustee, when the trustee has been elected by only one class), the required vote only by the applicable class or series will be required. Approval of shareholders is not required, however, for any transaction, whether deemed a merger, consolidation, reorganization or otherwise whereby the Fund issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. In the case of the conversion of the Fund to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan of reorganization which adversely affects the holders of Preferred Shares the action in question will also require the affirmative vote of the holders of at least two-thirds of the Fund’s Preferred Shares outstanding at the time, voting as a separate class, or, if such action has been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-Laws, the affirmative vote of the holders of at least a majority of the Fund’s Preferred Share outstanding at the time, voting as a separate class. None of the foregoing provisions may be amended except by the vote of at least two-thirds of the Common Shares and Preferred Shares voting together as a single class. The votes required to approve the conversion of the Fund from a closed-end to an open-end investment company or to approve transactions constituting a plan of reorganization which adversely affects the holders of Preferred Shares are higher than those required by the 1940 Act. The Board is divided into three classes, such a staggered board could delay for up to two years the replacement of a majority of the Board. The Board believes that the provisions of the Declaration relating to such higher votes are in the best interest of the Fund and its shareholders. Note, the Fund’s staggered Board could delay for up to two years the replacement of a majority of the Board. Reference should be made to the Declaration on file with the SEC for the full text of these provisions.

The Declaration provides that the obligations of the Fund are not binding upon the trustees of the Fund individually, but only upon the assets and property of the Fund, and that the trustees shall not be liable for errors of judgment or mistakes of fact or law. Nothing in the Declaration, however, protects a trustee against any liability to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

The provisions of the Declaration described above could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The overall effect of these provisions is to render more difficult the accomplishment of a merger or the assumption of control by a third party. They provide, however, the advantage of potentially requiring persons seeking control of the Fund to negotiate with its management regarding the price to be paid and facilitating the continuity of the Fund’s investment objectives and policies. The Board of the Fund has considered the foregoing anti-takeover provisions and concluded that they are in the best interests of the Fund and its Common Shareholders.

REPURCHASE OF FUND SHARES; CONVERSION TO OPEN-END FUND

general market and economic conditions and other factors. Because shares of a closed-end investment company may frequently trade at prices lower than NAV, the Fund’s Board has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from NAV in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at NAV, or the conversion of the Fund to an open-end investment company. There can be no assurance, however, that the Board will decide to take any of these actions, or that share repurchases or tender offers, if undertaken, will reduce market discount. On August 1, 2017, the Fund’s Board renewed the Fund’s open market share repurchase program under which the Fund may repurchase up to 10% of its Common Shares. Since the inception of the Fund’s share repurchase program through April 26, 2018, the Fund has not repurchased any Common Shares under the program.

Notwithstanding the foregoing, at any time if the Fund has Preferred Shares outstanding, the Fund may not purchase, redeem or otherwise acquire any of its Common Shares unless (1) all accrued preferred shares dividends have been paid and (2) at the time of such purchase, redemption or acquisition, the NAV of the Fund’s portfolio (determined after deducting the acquisition price of Common Shares) is at least 200% of the liquidation value of the outstanding preferred shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon). The staff of the SEC currently requires that any tender offer made by a closed-end investment company for its shares must be at a price equal to the NAV of such shares at the close of business on the last day of the tender offer. Any service fees incurred in connection with any tender offer made by the Fund will be borne by the Fund and will not reduce the stated consideration to be paid to tendering shareholders.

Subject to its investment limitations, the Fund may borrow to finance the repurchase of shares or to make a tender offer. Interest on any borrowings to finance share repurchase transactions or the accumulation of cash by the Fund in anticipation of share repurchases or tenders will reduce the Fund’s net income. Any share repurchase, tender offer or borrowing that might be approved by the Board would have to comply with the Securities Exchange Act of 1934, as amended, and the 1940 Act and the rules and regulations thereunder.

Although the decision to take action in response to a discount from NAV will be made by the Board of the Fund at the time it considers such issue, it is the Board’s present policy, which may be changed by the Board, not to authorize repurchases of Common Shares or a tender offer for such shares if (1) such transactions, if consummated, would (a) result in the delisting of the Common Shares from the NYSE, or (b) impair the Fund’s eligibility for treatment as a RIC under the Code, or impair the Fund’s status as a registered closed-end investment company under the 1940 Act; (2) the Fund would not be able to liquidate portfolio securities in an orderly manner and consistent with the Fund’s investment objectives and policies in order to repurchase shares; or (3) there is, in the Board’s judgment, any (a) material legal action or proceeding instituted or threatened challenging such transactions or otherwise materially adversely affecting the Fund, (b) general suspension of or limitation on prices for trading securities on the NYSE, (c) declaration of a banking moratorium by Federal or state authorities or any suspension of payment by United States or state banks in which the Fund invests, (d) material limitation affecting the Fund or the issuers of its portfolio securities by federal or state authorities on the extension of credit by lending institutions or on the exchange of foreign currency, (e) commencement of war, armed hostilities or other international or national calamity directly or indirectly involving the United States, or (f) other event or condition which would have a material adverse effect (including any adverse tax effect) on the Fund or its shareholders if shares were repurchased. The Board of the Fund may in the future modify these conditions in light of experience.

If the Fund converted to an open-end company, it would be required to redeem all preferred shares then outstanding, and the Fund’s common shares would no longer be listed on the NYSE. In contrast to a closed-end investment company, shareholders of an open-end investment company may require the company to redeem their shares at any time (except in certain circumstances as authorized by or under the 1940 Act) at their NAV, less any redemption charge that is in effect at the time of redemption. As a result, conversion to open-end status may require changes in the management of the Fund’s portfolio in order to meet the liquidity requirements applicable to open-end funds. Because portfolio securities may have to be liquidated to meet redemptions, conversion could affect the Fund’s ability to meet its investment objectives or to use certain investment policies and techniques described above. If converted to an open-end fund, the Fund expects to pay all redemptions in cash, but intends to reserve the right to pay redemption requests in a combination of cash or securities. If such partial payment in securities were made, investors may incur brokerage costs in converting such securities to cash. If the Fund were converted to an open-end fund, it is likely that new Common Shares would be sold at NAV plus a sales load. See “Repurchase of Fund Shares; Conversion to Open-End Fund” in the SAI for a discussion of the voting requirements applicable to the conversion of the Fund to an open-end investment company.

Before deciding whether to take any action if the Fund’s Common Shares trade below NAV, the Board of the Fund would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund’s portfolio, the impact of any action that might be taken on the Fund or its shareholders and market considerations. Based on these considerations, even if the Fund’s shares should trade at a discount, the Board may determine that, in the interest of the Fund and its shareholders, no action should be taken.

TAX MATTERS

The following information is meant as a general summary for U.S. shareholders. Please see the SAI for additional information. Investors should rely on their own tax adviser for advice about the particular federal, state and local tax consequences to them of investing in the Fund.

The recently enacted tax legislation commonly referred to as Tax Cuts and Jobs Act (the “Tax Act”) makes significant changes to the U.S. federal income tax rules for taxation of individuals and corporations, generally effective for taxable years beginning after December 31, 2017. Many of the changes applicable to individuals are temporary and would apply only to taxable years beginning after December 31, 2017 and before January 1, 2026. There are only minor changes with respect to the specific rules only applicable to a RIC, such as the Fund. The Tax Act, however, makes numerous other changes to the tax rules that may affect shareholders and the Fund. You are urged to consult with your own tax advisor regarding how the Tax Act affects your investment in the Fund.

The Fund has elected and intends to qualify each year to be treated as a RIC under Subchapter M of the Code. In order to qualify for treatment as a RIC, the Fund must satisfy certain requirements regarding the sources of its income, the diversification of its assets and the distribution of its income. As a RIC, the Fund is not expected to be subject to federal income tax. The Fund primarily invests in municipal securities (as defined above) issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico or Guam) or municipal securities whose income is otherwise exempt from regular federal and California income taxes. To qualify to pay exempt-interest dividends, which are treated as items of interest excludable from gross income for federal income tax purposes, at least 50% of the value of the total assets of the Fund must consist of obligations exempt from regular income tax as of the close of each quarter of the Fund’s taxable year. If the proportion of taxable investments held by the Fund exceeds 50% of the Fund’s total assets as of the close of any quarter of any Fund taxable year, the Fund would not for that taxable year satisfy the general eligibility test that would otherwise permit it to pay exempt-interest dividends. Substantially all of the Fund’s dividends paid to you are expected to qualify as “exempt-interest dividends.” A shareholder treats an exempt-interest dividend as interest on state and local bonds exempt from regular federal income tax. Although the Fund

expects that under normal circumstances it will not invest in municipal securities the interest on which is subject to the federal alternative minimum tax, at times a portion of the income from municipal securities may be subject to the federal alternative minimum tax. Federal income tax law imposes an alternative minimum tax with respect to individuals, trust and estates. The Tax Act repealed the federal alternative minimum tax for corporations for tax years beginning after December 31, 2017. Interest on certain municipal securities, such as certain private activity bonds, is included as an item of tax preference in determining the amount of a taxpayer’s alternative minimum taxable income. Under normal circumstances, the Fund invests at least 80% of its Assets in securities the interest on which is not a tax preference item. If the Fund receives income from such municipal securities, a portion of the dividends paid by the Fund, although exempt from regular federal income tax, will be taxable to shareholders whose tax liabilities are determined under the federal alternative minimum tax. The Fund will annually provide a report indicating the percentage of the Fund’s income attributable to municipal securities and the percentage includable in federal alternative minimum taxable income.

In addition to exempt-interest dividends, the Fund may also distribute to its shareholders amounts that are treated as long-term capital gain or ordinary income (which may include short-term capital gains). These distributions are generally subject to regular federal income tax, whether or not reinvested in additional shares. Capital gain distributions are generally taxable at rates applicable to long-term capital gains regardless of how long a shareholder has held its shares. Long-term capital gains are taxable to non-corporate shareholders at rates of up to 20%. The Fund does not expect that any part of its distributions to shareholders from its investments will qualify for the dividends-received deduction available to corporate shareholders or as “qualified dividend income,” which is taxable to non-corporate shareholders at reduced U.S. federal income tax rates.

A 3.8% Medicare contribution tax generally applies to all or a portion of the net investment income of a shareholder who is an individual and not a nonresident alien for federal income tax purposes and who has adjusted gross income (subject to certain adjustments) that exceeds a threshold amount ($250,000 if married filing jointly or if considered a “surviving spouse” for federal income tax purposes, $125,000 if married filing separately, and $200,000 in other cases). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts. For these purposes, interest, dividends and certain capital gains are generally taken into account in computing a shareholder’s net investment income, but exempt-interest dividends are not taken into account.

As a RIC, the Fund will not be subject to federal income tax in any taxable year provided that it meets certain distribution requirements. As described in “Distributions” above, the Fund might not distribute some (or all) of its net capital gain. If the Fund retains any net capital gain or taxable net investment income, it will be subject to tax at regular corporate rates on the amount retained. If the Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who, if subject to federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their shares of such undistributed amount; (ii) will be deemed to have paid their proportionate shares of the tax paid by the Fund on such undistributed amount and will be entitled to credit that amount of tax against their federal income tax liabilities, if any; and (iii) will be entitled to claim refunds to the extent the credit exceeds such liabilities. For federal income tax purposes, the tax basis of shares owned by a shareholder of the Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the tax deemed paid by the shareholder.

Dividends declared by the Fund in October, November or December, payable to shareholders of record in such a month, and paid during the following January will be treated as having been received by shareholders in the year the distributions were declared.

Each shareholder will receive an annual statement summarizing the shareholder’s dividend and capital gains distributions.

capital gain or loss if the shares have been held for more than one year even though the increase in value in such Common Shares may be at least partly attributable to tax-exempt interest income. Present law taxes both long-term and short-term capital gains of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, however, long-term capital gains are taxed at rates of up to 20%. Short-term capital gains and other ordinary income are taxed to non-corporate shareholders at ordinary income rates. If a shareholder sells or otherwise disposes of Common Shares before holding them for six months, any loss on the sale or disposition will be treated as a long-term capital loss to the extent of any amounts treated as distributions to the Common Shareholder of long-term capital gain (including any amount credited to the Common Shareholder as undistributed capital gain). Any loss realized on a sale or exchange of shares of the Fund will be disallowed to the extent those shares of the Fund are replaced by substantially identical shares of the Fund (including shares acquired by reason of participation in the Plan) within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares, or to the extent the shareholder enters into a contract or option to repurchase shares within such period. In that event, the basis of the replacement shares of the Fund will be adjusted to reflect the disallowed loss.

Any interest on indebtedness incurred or continued to purchase or carry the Fund’s shares to which exempt-interest dividends are allocated is not deductible. Under certain applicable rules, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of the shares. In addition, if you receive social security or certain railroad retirement benefits, you may be subject to U.S. federal income tax on a portion of such benefits as a result of receiving investment income, including exempt-interest dividends and other distributions paid by the Fund.

The Fund may be required to withhold (as “backup withholding”) U.S. federal income tax from distributions (including exempt-interest dividends) and repurchase proceeds payable to a shareholder if the shareholder fails to provide the Fund with his or her correct taxpayer identification number or to make required certifications, or if the shareholder has been notified by the Internal Revenue Service (“IRS”) that he or she is subject to backup withholding. The backup withholding rate is 24%. Backup withholding is not an additional tax; rather, it is a way in which the IRS ensures it will collect taxes otherwise due. Any amounts withheld may be credited against a shareholder’s U.S. federal income tax liability.

The Fund may invest a portion of its assets in securities that generate income that is not exempt from regular federal or California income taxes.

California Tax Matters

The Fund’s regular monthly dividends will not be subject to California personal income tax to the extent they are paid out of income earned on obligations that, when held by individuals, pay interest that is exempt from taxation by California under California law (e.g., obligations of California and its political subdivisions) or federal law, so long as at the close of each quarter of the Fund’s taxable year at least 50% of the value of the Fund’s total assets consists of such obligations and the Fund designates such tax-exempt distributions pursuant to certain written notice requirements to its shareholders. The portion of the Fund’s monthly dividends that is attributable to income other than as described in the preceding sentence will be subject to the California income tax. The Fund expects to earn no or only a minimal amount of such non-exempt income. If you are an individual California resident, you will be subject to California personal income tax to the extent the Fund distributes any realized capital gains, or if you sell or exchange shares and realize a capital gain on the transaction.

Other State and Local Tax Matters

APPENDIX A: FACTORS AFFECTING MUNICIPAL SECURITIES IN CALIFORNIA

The following information constitutes only a brief summary of some of the general factors that may impact certain issuers of municipal bonds and does not purport to be a complete or exhaustive description of all adverse conditions to which the issuers of municipal bonds held by the Fund are subject. Additionally, many factors, including national economic, social and environmental policies and conditions, which are not within the control of the issuers of the municipal bonds, could affect or could have an adverse impact on the financial condition of the issuers. The Fund is unable to predict whether or to what extent such factors or other factors may affect the issuers of the municipal securities, the market value or marketability of the municipal securities or the ability of the respective issuers of the municipal bonds acquired by the Fund to pay interest on or principal of the municipal securities. This information has not been independently verified.

The Fund invests a high proportion of its assets in municipal securities of the State of California (the “State” or “California”). The payment of interest on and preservation of principal in these securities are dependent upon the continuing ability of California issuers and/or obligors of state, municipal and public authority debt obligations to meet their obligations thereunder. In addition to general economic pressures, certain California constitutional amendments, legislative measures, executive orders, administrative regulations and voter initiatives could adversely affect a California issuer’s ability to raise revenues to meet its financial obligations.

Special Risk Considerations Relating to California Municipal Securities

As described in the Prospectus, under normal circumstances, the Fund will invest at least 80 percent of its Managed Assets in municipal securities and other related investments the income from which is exempt from regular federal and California income tax. The Fund seeks to achieve its investment objectives by investing in tax-exempt California municipal securities that Nuveen Asset Management believes are underrated and undervalued or that represent municipal market sectors that are undervalued. The specific California municipal securities in which the Fund will invest will change from time to time. The Fund is therefore susceptible to political, economic, regulatory or other factors affecting issuers of California municipal securities.

The following information constitutes only a brief summary of a number of the complex factors which may impact issuers of California municipal securities and does not purport to be a complete or exhaustive description of all adverse conditions to which issuers of California municipal securities may be subject. Such information is derived from official statements utilized in connection with the issuance of California municipal securities, as well as from other publicly available documents. Such an official statement, together with any updates or supplements thereto, generally may be obtained upon request to the State’s Treasurer’s office. Such information has not been independently verified by the Fund and the Fund assumes no responsibility for the completeness or accuracy of such information. The summary below does not include all of the information pertaining to the budget, receipts and disbursements of the State that would ordinarily be included in various public documents issued thereby, such as an official statement prepared in connection with the issuance of general obligation bonds of the State. Additionally, many factors, including national, economic, social and environmental policies and conditions, which are not within the control of such issuers, could have an adverse impact on the financial condition of such issuers. The Fund cannot predict whether or to what extent such factors or other factors may affect the issuers of California municipal securities, the market value or marketability of such securities or the ability of the respective issuers of such securities acquired by the Fund to pay interest on or principal of such securities. The creditworthiness of obligations issued by local California issuers may be unrelated to the creditworthiness of obligations issued by California, and there is no assurance on the part of the State to make payments on such local obligations. There may be specific factors that are applicable in connection with investment in the obligations of particular issuers located within the State, and it is possible the Fund will invest in obligations of particular issuers as to which such specific factors are applicable. However, the information set forth below is intended only as a general summary and not as a discussion of any specific factors that may affect any particular issuer of California municipal securities.

A-1

General Economic Conditions

The State’s economy, the largest among the 50 states and one of the largest and most diverse in the world, has major components in high technology, trade, entertainment, manufacturing, government, tourism, construction and services. The relative proportion of the various components of the State’s economy closely resembles the make-up of the national economy. The California economy continues to benefit from broad-based growth.

Real GDP of the United States grew by 2.3 percent in 2017, reflecting positive contributions from personal consumption, business investment, and exports, and is expected to grow above 2 percent in 2018. The labor force expanded by 1.1 million while nonfarm employment increased by 2.1 million in 2017. The national unemployment rate reached 3.9 percent in April 2018, the lowest since December 2000. After the interest rate hikes in March, June and December 2017, the Federal Reserve is expected to continue gradually raising interest rates over the following few years.

California’s real GDP increased by 3.3 percent in 2016, and totaled $2.6 trillion at current prices, making California the sixth largest economy in the world. California’s unemployment rate fell to 4.2 percent in April 2018, the lowest on record since 1976. As the labor market is tightening, average wages are starting to rise but at a slower rather than in previous periods of very low unemployment due in part to the retirement of baby boomers.

Consumer prices are slowly increasing as commodity prices stabilize and wages continue to rise. California’s inflation rose by 2.9 percent in 2017 and is expected to increase by 3.0 percent and 2.9 percent in 2018 and 2019, respectively. In comparison, U.S. inflation rose by 2.1 percent in 2017 and is expected to increase by 2.1 percent and 2.2 percent in 2018 and 2019, respectively. Inflation remained concentrated in housing since 2014. Housing inflation increased by 3.3 percent in the U.S. and 4.9 percent in California in 2017.

Housing permits are starting to grow at a faster rate in 2018 compared to 2017, but there is still a shortage after years of permits lagging population growth. New housing units built in California were only 85,000 in 2017 due to fires that destroyed more than 13,000 units. The Governor estimates that residential building permits will continue to increase to around 174,000 by 2021, favoring multi-family units. Although this is lower than the approximately 180,000 permits per year needed to keep up with population growth, the increase in permits is expected to reduce housing inflation. The statewide median sales price of an existing single-family home was around $538,000 in 2017, the highest level since 2007. The State’s home prices are more than double the national median price of around $249,000, and increasing housing costs puts pressure on the State’s inflation. The median home price in California has been rising faster than median household income since 2011.

The risk of a recession remains, and many households still have not recovered fully from the last recession, making it more difficult for them to weather a recession. Even under continued growth, the federal deficit is expected to exceed $1 trillion per year, and debt to GDP levels are increasing. In the next recession, the deficit could rise much higher and force cuts to federal programs on which Californians depend.

Despite significant budgetary improvements during the last several years, there remain a number of risks that threaten the State’s fiscal condition, including the threat of recession, potentially unfavorable changes to federal fiscal policies and the significant unfunded liabilities of the two main State retirement systems, the California Public Employees’ Retirement System (“CalPERS”) and the California State Teachers’ Retirement System (“CalSTRS”). Although the State has paid down a substantial amount of these debts in the past several years and has put in place plans to pay off all major State retirement-related liabilities over the next three decades, the State faces hundreds of billions of dollars in other long-term cost pressures, and debts and liabilities, including State retiree pension and health care costs.

There can be no assurances that the State will not face fiscal stress and cash pressures again or that other changes in the State or national economies or in federal policies will not materially adversely affect the financial condition of the State.

California—Government

California’s Constitution provides for three separate branches of government: the legislative, the judicial and the executive. The Constitution guarantees the electorate the right to make basic decisions, including amending the Constitution and local government charters. In addition, California’s voters may directly influence the State’s government through the initiative, referendum and recall processes.

Local Governments

The primary units of local government in California are the 58 counties, which range in population from approximately 1,200 in Alpine County to approximately 10.2 million in Los Angeles County. Counties are responsible for the provision of many basic services, including indigent health care, welfare, jails, and public safety in unincorporated areas. There are also 482 incorporated cities in California and thousands of special districts formed for education, utilities, and other services. Spending and revenues collected by the State or by local governments has shifted over the past decades.

The fiscal condition of local governments has been constrained since Proposition 13, which added Article XIII A to the State Constitution, was approved by California voters in 1978. Proposition 13 reduced and limited the future growth of property taxes and limited the ability of local governments to impose “special taxes” (those devoted to a specific purpose) without two-thirds voter approval. Proposition 218, another constitutional amendment enacted by initiative in 1996, further limited the ability of local governments to raise taxes, fees, and other exactions. Counties, in particular, have had fewer options to raise revenues than many other local government entities, while they have been required to maintain many services.

In the aftermath of Proposition 13, the State provided aid to local governments from the General Fund to make up some of the loss of property tax moneys, including assuming principal responsibility for funding K-12 schools and community colleges. During the recession of the early 1990s, the Legislature reduced the post-Proposition 13 aid to local government entities other than K-12 schools and community colleges by requiring cities and counties to transfer some of their property tax revenues to school districts. However, the Legislature also provided additional funding sources, such as sales taxes, and reduced certain mandates for local services funded by cities and counties.

The 2004 Budget Act, related legislation and the enactment of Proposition 1A in 2004 and Proposition 22 in 2010 dramatically changed the State-local fiscal relationship. These constitutional and statutory changes implemented an agreement negotiated between the Governor and local government officials (the “state-local agreement”) in connection with the 2004 Budget Act.

As part of the state-local agreement, voters at the November 2004 election approved Proposition 1A. This Proposition amended the State Constitution to, among other things, reduce the Legislature’s authority over local government revenue sources by placing restrictions on the State’s access to local governments’ property, sales, and vehicle license fees (“VLF”) revenues as of November 3, 2004. This proposition permitted the State to borrow from local government funds. Proposition 22, adopted on November 2, 2010, supersedes Proposition 1A and completely prohibits any future borrowing by the State from local government funds, and generally prohibits the Legislature from making changes in local government funding sources. Allocation of local transportation funds cannot be changed without an extensive process.

The 2011 Budget Act included a major realignment of public safety programs from the State to local governments. The realignment was designed to move program and fiscal responsibility to the level of government that can best provide the service, eliminate duplication of effort, generate savings and increase flexibility. Proposition 30, approved by voters in November 2012, placed into the State Constitution the current statutory provisions transferring 1.0625 percent of the State sales tax to local governments to fund the “realignment” program for many services including housing criminal offenders. The sales tax provisions of

A-3

Proposition 30 expired December 31, 2016; however, the personal income tax rates for high-income taxpayers, which were set to expire on December 31, 2018, were extended through tax year 2030 by Proposition 55 in the November 2016 election. Under specified conditions, beginning in fiscal year 2018-19, Proposition 55 also authorizes the use of up to $2 billion in a fiscal year from these revenues for health care.

California Finances

The State’s moneys are segregated into the General Fund and over 1,000 other funds, including special, bond, federal and other funds. The General Fund consists of revenues received by the State’s Treasury and is not required by law to be credited to any fund and earnings from the investment of California moneys not allocable to another fund. The General Fund is the principal operating fund for the majority of governmental activities and is the depository of most of the major revenue sources of the State.

The following is a summary of California’s major revenue sources:

• Personal Income Tax. The California personal income tax is closely modeled after the federal income tax law. It is imposed on net taxable income (gross income less exclusions and deductions), with rates ranging from 1 to 12.3 percent. In addition, a 1 percent surcharge is imposed on taxable income above $1 million and proceeds from such tax are dedicated to the Mental Health Services Fund. The personal income tax is adjusted annually by the change in the consumer price index to prevent taxpayers from being pushed into a higher tax bracket without a real increase in income. Personal, dependent, and other credits are allowed against the gross tax liability. Taxpayers may be subject to an alternative minimum tax (“AMT”), which is much like the federal AMT.

Taxes on capital gains realizations, which are largely linked to stock market and real estate performance, can add a significant dimension of volatility to personal income tax receipts. Forecasting capital gains is extremely difficult, as the forecasts can change rapidly during a year due to abrupt changes in asset markets and the overall economy. For example, capital gains tax receipts accounted for nearly 9 percent of General Fund revenues and transfers in fiscal year 2007-08, but dropped below 5 percent in fiscal year 2008-09, and below 4 percent in fiscal year 2009-10. The volatility in these percentages is primarily due to an underlying volatility in the level of capital gains tax revenues, rather than to volatility in other General Fund revenues and transfers.

• Sales Tax. The sales tax is imposed upon retailers for the privilege of selling tangible personal property in California. Most retail sales and leases are subject to the tax. However, exemptions have been provided for certain essentials such as food for home consumption, prescription drugs, gas delivered through mains and electricity. Other exemptions provide relief for a variety of sales ranging from custom computer software to aircraft. Effective January 1, 2017, the base State and local sales tax was 7.25 percent. Most cities and counties have increased the sales tax percentage in their jurisdiction above the base amount.

• Corporation Tax. The State’s corporate tax revenue is derived from franchise tax, corporate income tax, additional taxes on banks and other financial corporations, a State AMT, a tax on the profits of Sub-Chapter S corporations, and fees and taxes paid by limited liability companies.

• Insurance Tax. The majority of insurance written in the State, subject to certain exceptions, is subject to a 2.35 percent gross premium tax.

• Special Fund Revenues. The State Constitution and statutes specify the uses of certain revenues, and such receipts are accounted for in various special funds. While these funds are not directly available to repay State general obligation bonds, the General Fund may, when needed to meet cash flow needs, temporarily borrow from certain special funds. In general, special fund revenues comprise three categories of income: receipts from tax levies allocated to specified functions; charges for certain services provided by the State government; and rental royalties.

• Taxes on Tobacco Products. Cigarette and tobacco taxes primarily affect special funds, though some goes to the General Fund.

A-4

• Taxes on Cannabis Products. Voters approved Proposition 64 in November 2016, which legalized the recreational use of cannabis within California for persons age 21 and over, effective November 9, 2016. The measure also levies new excise taxes on the cultivation and retail sale of both recreational and medical cannabis as of January 1, 2018 to be spent for specific purposes.

California Budget Process

California’s fiscal year begins on July 1st and ends on June 30th of the following year. Under the California Constitution, money may be drawn from the Treasury only through an appropriation made by law. The primary source of the annual expenditure is the annual Budget Act as approved by the Legislature and signed by the Governor. The annual budget is proposed by the Governor by January 10 of each year for the next fiscal year (the “Governor’s Budget”). California law requires the annual proposed Governor’s Budget to provide for projected revenues equal to or in excess of projected expenditures for the ensuing fiscal year. Following the submission of the Governor’s Budget, the Legislature takes up the proposal. During late spring, usually in May, the Department of Finance submits revised revenue and expenditure estimates (known as the May Revision) for both the current and budget years to the Legislature. The Budget Act, which follows the May Revision, must be approved by a majority vote of each House of the Legislature.

Appropriations also may be included in legislation other than the Budget Act. With limited exceptions, bills containing General Fund appropriations must be approved by a two-thirds majority vote in each House of the Legislature and be signed by the Governor. Continuing appropriations, available without regard to fiscal year, may also be provided by statute or the California Constitution.

The Governor may reduce or eliminate specific line items in the Budget Act or any other appropriations bill without vetoing the entire bill. Such individual line-item vetoes are subject to override by a two-thirds majority vote of each House of the Legislature.

The Balanced Budget Amendment (Proposition 58, approved by the voters in 2004) requires the State to enact a balanced budget, establishes a special reserve in the General Fund, restricts future borrowings to cover budget deficits, and provides for mid-year budget adjustments if the budget falls out of balance. The Legislature may not pass a budget bill in which General Fund expenditures exceed estimated General Fund revenues and fund balances at the time of passage and as set forth in the budget bill. As a result of the requirements of Proposition 58, the State must, in some cases, take more immediate actions to correct budgetary shortfalls. For example, if, after passage of the Budget Act, the Governor determines that the State is facing substantial revenue shortfalls or spending deficiencies, the Governor is authorized to declare a fiscal emergency and propose legislation to address the emergency. The Legislature is called in to special session to address this proposal. If the Legislature fails to send legislation to the Governor to address the fiscal emergency within 45 days, it is prohibited from acting on any other bills or adjourning until fiscal legislation is passed. Such fiscal emergencies were declared in 2008, 2009, 2010, and 2011, and the Legislature was called into various special sessions to address budget shortfalls. Proposition 58 also prohibits certain future borrowings to cover budget deficits. These restrictions apply to general obligation bonds, revenue bonds and certain other forms of long-term borrowings, but do not apply to certain other types of borrowing, such as (i) short-term borrowing to cover cash shortfalls in the General Fund (including revenue anticipation notes or revenue anticipation warrants currently used by the State), or (ii) inter-fund borrowings.

In addition to Proposition 58, a number of other laws and constitutional amendments have been enacted over the years, often through voter initiatives, which have made it more difficult to raise the State’s taxes, have restricted the use of the General Fund or special fund revenues, or have otherwise limited the Legislature and Governor’s discretion in enacting budgets. Examples of constraints on the budget process include Proposition 13 (requiring a two-thirds vote in each House of the Legislature to change California taxes enacted for the purpose of increasing revenues collected), Proposition 98 (requiring a minimum percentage of General Fund revenues be spent on local education), Proposition 49 (requiring expanded State funding for before and after school

A-5

programs), Proposition 10 (raising taxes on tobacco products but mandating the expenditure of such revenues), Proposition 56 (further raising taxes on tobacco products and again mandating the expenditures of such revenues), Proposition 63 (imposing a 1 percent tax surcharge on taxpayers with annual taxable income of more than $1 million in order to fund mental health services and limiting the Legislature or Governor from redirecting funds now used for mental health services), Proposition 22 (restricting the ability of the State to use or borrow money from local governments and moneys dedicated to transportation financing, and prohibiting the use of excise taxes on motor vehicle fuels to offset General Fund costs of debt service on certain transportation bonds), Proposition 30 (transferring 1.0625 percent of State sales tax to local governments to fund realignment), and Proposition 39 (requiring corporations to base their State tax liability on sales in California). Proposition 25 was intended to end delays in the adoption of the annual budget by changing the legislative vote necessary to pass the budget bill from two-thirds to majority vote and requiring the legislators to forgo their pay if the Legislature fails to pass the budget bill on time. Proposition 2, passed in November 2014, changes the way the State pays down debt and saves money in reserves.

California Budget

Budget deficits in California have recurred from year-to-year for over a decade prior to the 2013-14 fiscal year. Weakness in the State economy caused State tax revenues to decline precipitously, resulting in large budget gaps and cash shortfalls. In addition to the economic downturn in 2008, California’s chronic budget crises are also a result of State spending commitments funded by temporary spikes in revenues. Once revenues return to their normal trend or drop precipitously, these commitments cannot be sustained, and dramatic cuts to programs and/or tax increases sometimes have been required. Budgets also have repeatedly been balanced using, at least in part, unrealized assumptions and one-time or temporary measures.

California’s budget challenges were exacerbated by a “wall of debt,” which was an unprecedented level of debt, deferrals and budgetary obligations that accumulated for over a decade. At the end of the 2010-11 fiscal year, “wall of debt” obligations had reached $34.7 billion. In addition, the State faces hundreds of billions of dollars in other long-term cost pressures, debts and liabilities. As a result, the State has been paying for past expenses and will do so for the foreseeable future. The State currently has $291 billion in long-term costs, debts and liabilities. The majority of these liabilities ($287 billion) are related to retirement costs of State and UC employees.

As the State’s economy has recovered since the last recession, the State’s budgets have significantly expanded government spending. The State has paid down some of its debt and has addressed some long-standing problems—such as implementing plans to restore fiscal health to State pension plans and making improvements to the State’s water system.

The passage of Proposition 2 in November 2014 gives the State a means to seek to avoid repeating the prior boom-and-bust cycles. Under Proposition 2, spikes in capital gains are used, in part, to save money for the next recession through the establishment of a rainy day fund (otherwise known as the “Budget Stabilization Account” or the “BSA”), and to pay down the State’s debts and liabilities. The Proposition also sets requirements as to how money in the rainy day fund is used and requires that the State provide multi-year budget forecasts to help better manage the State’s longer term finances. It is estimated that the State will end the 2017-18 fiscal year with a BSA balance of $9.4 billion, with additional reserves of $7.3 billion.

Nonetheless, despite the significant budget improvements during the least several years, a number of risks threaten the State’ financial condition. These risks include, but are not limited to, the threat of recession, potentially unfavorable changes to federal fiscal policies and the uncertain impact of the recent changes in federal tax law, health care costs, capital gains volatility, climate change, and debts and liabilities. By the end of fiscal year 2018-19, the economy will have had the longest expansion since the recovery after World War II, and another recession is ultimately inevitable. The stock market has been at an all-time high and has been volatile. A sudden fall would likely adversely affect investment and hiring decision at California companies, even in the

A-6

absence of a recession. The May revision to the 2018-19 budget includes a preliminary analysis of the projected effects of recent federal tax reform. The impact of the recent federal tax reform is not known, including behavioral impacts which may not be apparent for some time. The State’s Medicaid program is one of the State’s largest expenditures, and as the State continues to implement federal health care reform or as the federal government continues to make significant policy changes, the State’s spending on health care costs could increase significantly and State budgetary spending could become more dependent on the inflation rate of health costs.

The State also faces significant unfunded liability of the State’s two main retirement systems, CalSTRS and CalPERS. The State has committed to significant increases in the annual payments to these two systems to reduce their unfunded liabilities, including a $6 billion supplemental pension payment to CalPERS in fiscal year 2017-18. Despite these efforts, the liabilities continue to rise. The State now has plans in place to pay off these liabilities over the next 30 years based on current assumptions. The State also has significant unfunded liability with respect to other postemployment benefits (“OPEB”). Strategies to prefund these costs were established in 2015 and today, nearly all state employees contribute toward prefunding OPEM costs.

The discussion below of the proposed fiscal year 2018-19 budget and the fiscal year 2017-18 budget is based on estimates and projections of revenues and expenditures by the Governor’s administration, and must not be construed as statements of fact. These estimates and projections are based upon various assumptions, which may be affected by numerous factors, including future economic conditions in California and the United States, and there can be no assurance that the estimates will be achieved. There can be no assurances that the State will not face fiscal stress and cash pressures again, or that other changes in the State or national economics or in State of federal policies will not materially adversely affect the State’s financial condition.

Proposed Fiscal Year 2018-19 Budget

Governor Brown released proposed the fiscal year 2018-19 budget on January 10, 2018 and revised the proposed budget on May 11, 2018 (collectively, the “Proposed 2018 Budget”). The Proposed 2018 Budget proposes a multi-year plan that is balanced through fiscal year 2021-22, provides for the rainy day fund to reach its maximum constitutional goal for fiscal year 2018-19, and continues to pay down budgetary debt from past years.

The Proposed 2018 Budget estimates total General Fund revenues and transfers to be $133.5 billion for fiscal year 2018-19, an increase of approximately $3.7 billion compared to the prior fiscal year. The increases are primarily from personal income tax and, to a lesser extent, corporate tax. The Proposed 2018 Budget estimates that the fiscal year will begin with a prior year fund balance of $8.5 billion. The May revision of the budget reflects almost $8 billion in higher revenue than what was estimated at the time that the initial budget was released in January. As the Legislative Analyst Office (“LAO”) notes, a large portion of the revenue increase is offset by formula-driven constitutional spending requirements and other increases resulting from caseload changes and federal requirements. After satisfying these higher spending requirements, the LAO estimates that there is $4.1 billion in additional discretionary resources.

The Proposed 2018 Budget estimates expenditures to be $137.6 billion for fiscal year 2018-19, an increase from $10.5 billion from the prior fiscal year. The biggest expenditures from the General Fund are in K-12 education programs ($55.8 billion), health and human services ($38.9 billion) and higher education ($15.7 billion). The Proposed 2018 Budget includes almost $4 billion in one-time General Fund spending, focused on infrastructure, homelessness and mental health.

The Governor proposes that the State would end fiscal year 2018-19 with $17 billion in total reserves, comprised of $13.8 billion for the rainy day fund and $3.2 billion in the Special Fund for Economic Uncertainties (“SFEU”). While the State’s reserves have increased, as the LAO notes, the current level of reserves is not

A-7

sufficient to fully cover the costs of a moderate or severe recession. If the State faces a recession in the coming years, the State would need to take many billions of dollars in actions over a multiyear period to bring the budget back into balance.

Despite the recent budgetary improvements, there remain a number of risks that threaten the State’s fiscal condition, including the need to repay billions of dollars of obligations that were deferred to balance budgets during the economic downturn. The State continues to need to address unfunded retiree benefits. In addition, California’s revenues (particularly the personal income tax) can be volatile and correlate to overall economic conditions. Sudden tax revenue declines may return with little warning.

Fiscal Year 2017-18 State Budget

Governor Brown signed the fiscal year 2017-18 budget on June 27, 2017 (the “2017 Budget”). The 2017 Budget anticipated that the State will need to counter the potential fiscal impacts of federal policy changes and the end of the current economic expansion. Accordingly, the 2017 Budget continued to increase the State’s rainy day fund and pay down accumulated debts and liabilities. The 2017 Budget projected that $2.6 billion will be added to the State’s reserves in fiscal year 2017-18 and the fiscal year will end with nearly $9.9 billion in reserves, which consists of $8.5 billion in the rainy day fund and $1.4 billion in the SFEU. The LAO has consistently encouraged and supported the decision to build reserves in preparation for the next economic downturn.

The 2017 Budget estimated total General Fund revenues and transfers to be $125.9 for fiscal year 2017-18, an increase in revenues and transfers by $7.3 billion or 6.2 percent compared to the prior fiscal year. This increase was primarily attributed to an estimated net 5 percent increase in the State’s “big three” General Fund taxes: the personal income, sales and use, and corporation taxes. The estimated net 5 percent increase reflected in the 2017 Budget is higher than what was included in the Governor’s proposed budget for fiscal year 2017-18 and consistent with the LAO’s expectations for a normal growth year. The personal income tax estimate for fiscal year 2017-18 reflected a $140 million revenue loss associated with the expansion of the State’s Earned Income Tax Credit to self-employment income and taxpayers with incomes up to $22,300.

The 2017 Budget estimated total General Fund expenditures of approximately $125.1 billion, which is a $3.7 billion or 3.0 percent increase compared to expenditures in the prior fiscal year. The 2017 Budget continued to include substantial funding for education, including total funding of $92.5 billion for K-12 education programs ($54.1 billion from the General Fund) and $32.5 billion total funding for higher education ($17.7 billion from the General Fund). Significant expenditures also include $161 billion for the Health and Human Services Agency ($35 billion from the General Fund), $11.4 billion for the Department of Corrections and Rehabilitation ($11.1 billion from the General Fund), and $9.2 billion for the Natural Resources Agency ($2.9 billion from the General Fund). The 2017 Budget allocated $2.8 billion of funding to begin implementation of the Road Repair Accountability Act of 2017. The LAO has stated that attention to transportation funding makes sense given that funding levels have been insufficient to meet the needs of the State’s aging infrastructure and recommended that highway maintenance be the highest priority for new funding.

The State continued to have hundreds of billions of dollars in liabilities for deferred maintenance on its aging infrastructure and for retiree health care benefits for State employees and various pension benefits. These retirement liabilities have continued to grow due to poor investment returns and changes in investment returns. Without additional action, paying off retirement liabilities will require an increasing portion of the State budget. The 2017 Budget reflects a $6 billion supplemental payment to CalPERS through a loan from the Surplus Money Investment Fund, which the Department of Finance projects will save $11 billion in State contributions to CalPERS from all State fund sources over the next two decades, assuming actuarial and investment assumptions are realized. The General Fund share of the repayment came from Proposition 2 revenues dedicated to reducing debts and long-terms liabilities.

Municipal Bankruptcies

Municipalities in California may declare bankruptcy, which increases the risk of default on municipal bonds. According to the LAO, except for K-12 education, the State does not have a significant role in monitoring the fiscal health of localities. Instead, the responsibility for reviewing local government fiscal conditions rests with local communities.

California provides its local governments with broad authority to file for Chapter 9 bankruptcy, but generally requires cities, counties and special districts to engage in a “neutral evaluation” process prior to filing for Chapter 9 relief. When a local government files for Chapter 9, the locality receives an “automatic stay” that stops the collection activity by creditors and protects the locality from litigation. A court must determine if the locality is eligible for Chapter 9 protection, and, if so, the locality must develop a plan of adjustment. Creditors and the court must approve the plan adjustment. Once the court approves the plan of adjustment, it creates a new contractual agreement between the locality and its creditors. The Chapter 9 process can take several years to be resolved.

In 2012, one California locality completed its Chapter 9 process and three other California localities filed for Chapter 9 bankruptcy. Of the three localities that filed for Chapter 9 bankruptcy in 2012, one did not exit bankruptcy until 2015 and another’s plan to exit bankruptcy was not confirmed until 2017. California municipalities continue to be at risk for Chapter 9 bankruptcy as retirement liabilities increase at the local level. The use of Chapter 9 bankruptcy filings by local governments could have an impact on creditors and parties with whom they contract, including bondholders. In addition, bankruptcies at the local level could impact the State’s overall fiscal outlook.

Ratings

The State’s fiscal situation increases the risk of investing in California municipal securities, including the risk of potential issuer default, and also heightens the risk that the prices of California municipal securities, and the Fund’s net asset value, will experience greater volatility.

Fitch, S&P, and Moody’s assign ratings to California’s long-term general obligation bonds, which represent their opinions as to the quality of the municipal bonds they rate. The ratings are general and not absolute standards of quality. Consequently, municipal bonds with the same maturity, coupon and rating may have different yields while obligations with the same maturity and coupon with different ratings may have the same yields. In 2009 and 2010, California’s general obligation bond ratings were significantly downgraded by Moody’s (to Baa1), S&P (to A-), and Fitch (to BBB). The State’s credit ratings had not been that low since 2003 and 2004. Since 2010, the credit ratings have been increasing, though the State has one of the lowest bond ratings of any state. In June 2014, Moody’s raised the State’s general obligation rating to “Aa3”; in July 2015, S&P raised the State’s general obligation credit rating to “AA-”, the State’s highest rating from S&P since 2000; and Fitch raised the rating to “AA-” in August 2016. However, these upward revisions reflected a recalibration of certain public finance ratings and did not reflect a change in credit quality of the issuer or issuers.

There can be no assurance that such ratings will be maintained in the future. The State’s credit rating, and any future revisions or withdrawal of a credit rating, could have a negative effect on the market price of the State’s general obligation bonds, as well as notes and bonds issued by California’s public authorities and local governments. Lower credit ratings make it more expensive for the State to raise revenue, and in some cases, could prevent the State from issuing general obligation bonds in the quantity otherwise desired. Further, downgrades can negatively impact the marketability and price of securities in the Fund’s portfolio.

California Indebtedness and Other Obligations

California’s Treasurer is responsible for the sale of debt obligations of the State and its various authorities and agencies. The State has always paid when due the principal of and interest on its general obligation bonds, general obligation commercial paper notes, lease-revenue obligations and short-term obligations.

As of February 1, 2018, the State had approximately $82.3 billion of outstanding general obligation bonds and lease revenue bonds payable principally from the General Fund or from lease payments paid from the operating budget of the respective lessees, which operating budgets are primarily, but not exclusively, derived from the General Fund. As of February 1, 2018, there were approximately $32.1 billion of authorized and unissued long-term voter-approved general obligation bonds, which when issued will be payable principally from the General Fund and approximately $4.2 billion for authorized but unissued lease-revenue bonds.

Current State debt obligations include:

• General Obligation Bonds. California’s Constitution prohibits the creation of general obligation indebtedness of California unless a bond measure is approved by a majority of the electorate voting at a general election or direct primary. Each general obligation bond act provides a continuing appropriation from the General Fund of amounts for the payment of debt service on the related general obligation bonds, subject under State law only to the prior application of moneys in the General Fund to the support of the public school system and public institutions of higher education. Under California’s Constitution, the appropriation to pay debt service on the general obligation bonds cannot be repealed until the principal and interest on the bonds have been paid. Certain general obligation bond programs, called “self-liquidating bonds,” receive revenues from specified sources so that moneys from the General Fund are not expected to pay debt service, but the General Fund will pay the debt service if the specified revenue source is not sufficient. The principal self-liquidating general obligation bond program is the veteran general obligation bonds, supported by mortgage repayments from housing loans made to military veterans. General obligation bonds are typically authorized for infrastructure and other capital improvements at the State and local level. Pursuant to the State Constitution, general obligation bonds cannot be used to finance State budget deficits.

As of February 1, 2018, the State had authorized and outstanding approximately $73.8 billion aggregate principal amount of long-term general obligation bonds, of which approximately $73.1 billion were payable primarily from the State’s General Fund, and approximately $738.9 million were “self-liquidating” bonds payable first from other special revenue funds. As of February 1, 2018, there were unused voter authorizations for the future issuance of approximately $32.3 billion long-term general obligation bonds, some of which may first be issued as commercial paper notes. Of this unissued amount, approximately $32.1 billion were payable primarily from the General Fund, and approximately $261.1 million were “self-liquidating” bonds payable first from other special revenue funds.

• Variable Rate General Obligations Bonds. The general obligation bond law permits the State to issue as variable rate indebtedness up to 20 percent of the aggregate amount of long-term general obligation bonds outstanding. As of February 1, 2018, the State had outstanding a $4.1 billion principal amount of variable rate general obligation bonds, representing about 5.6 percent of the State’s total outstanding general obligation bonds. If the approximately $1.7 billion of variable rate general obligation bonds having mandatory tender dates cannot be remarketed on their respective scheduled mandatory tender dates, there is no default but the interest rate on the series of such bonds not remarketed on such date would be increased in installments thereafter until such bonds can be remarketed or refunded or are paid at maturity. The State is obligated to redeem, on the applicable purchase date, any weekly and daily variable rate demand obligations (“VRDOs”) tendered for purchase if there is a failure to pay the related purchase price of such VRDOs on such purchase date from proceeds of the remarketing thereof, or from liquidity support related to such VRDOs. The State has not entered into any interest rate hedging contracts in relation to any of its variable rate general obligation bonds.

A-10

• General Obligation Commercial Paper Program. Pursuant to legislation enacted in 1995, voter-approved general obligation indebtedness may be issued either as long-term bonds or, for some but not all bond acts, as commercial paper notes. Commercial paper notes may be renewed or refunded by the issuance of long-term bonds. The State uses commercial paper notes to provide flexibility for bond programs, such as to provide interim funding of voter-approved projects and to facilitate refunding of variable rate bonds into fixed rate bonds. Commercial paper notes are not included in the calculation of permitted variable rate indebtedness described above under “Variable Rate General Obligation Bonds” and are not included in the figures provided above under “General Obligation Bonds.” As of February 1, 2018, a total of $2.2 billion in principal amount of commercial paper notes is authorized under agreements with various banks.

• Bank Arrangements. In connection with the letters of credit or other credit facilities obtained by the State in connection with VRDOs and the commercial paper program (“CP”), the State has entered into a number of reimbursement agreements or other credit agreements with a variety of financial institutions. These agreements include various representations and covenants of the State, and the terms by which the State would be required to pay or repay any obligations thereunder. To the extent that VRDOs or CP offered to the public cannot be remarketed over an extended period (whether due to downgrades of the credit ratings of the institution providing credit enhancement or other factors) and the applicable financial institution is obligated to purchase VRDOs or CP, interest payable by the State pursuant to the reimbursement agreement or credit agreement would generally increase over current market levels relating to the VRDOs or CP, and, with respect to VRDOs, the principal repayment period would generally be shorter than the period otherwise applicable to the VRDOs. In addition, after the occurrence of certain events of default as specified in a credit agreement, payment of the related VRDOs may be further accelerated and payment of related CP, as applicable, may also be accelerated and interest payable by the State on such VRDOs or CP could increase significantly.

• Lease-Revenue Obligations. The State builds and acquires facilities through the issuance of lease-revenue obligations, in addition to general obligation bonds. Such borrowing must be authorized by the Legislature in a separate act or appropriation. Under these arrangements, the State Public Works Board (“SPWB”), another State or local agency or a joint powers authority issues bonds to pay for the acquisition or construction of facilities, such as office buildings, university buildings, courthouses or correctional institutions. These facilities are leased to State agencies, the California State University (“CSU”) or the Judicial Council under a long-term lease that provides the source of payment of the debt service on the lease-revenue bonds. Under applicable court decisions, such lease arrangements do not constitute the creation of “indebtedness” within the meaning of State Constitutional provisions that require voter approval. As of February 1, 2018, the State had lease revenue obligations of approximately $9.2 billion for supported issues outstanding from the General Fund and approximately $4.2 billion for authorized but unissued bonds.

• Non-Recourse Debt. Certain State agencies and authorities issue revenue obligations for which the General Fund has no liability. These revenue bonds represent obligations payable from the State’s revenue-producing enterprises and projects (e.g., among other revenue sources, taxes, fees and/or tolls) and conduit obligations payable only from revenues paid by private users or local governments of facilities financed by the revenue bonds. In each case, such revenue bonds are not payable from the General Fund. The enterprises and projects include transportation projects, various public works projects, public and private educational facilities, housing, health facilities and pollution control facilities. State agencies and authorities had approximately $64.2 billion aggregate principal amount of revenue bonds and notes which are non-recourse to the General Fund outstanding as of June 30, 2017.

• Build America Bonds. In February 2009, the U.S. Congress enacted certain new municipal bond provisions as part of the American Recovery and Reinvestment Act, which allows municipal issuers such as the State to issue Build America Bonds (“BABs”) for new infrastructure investments. BABs are bonds whose interest is subject to federal income tax, but the U.S. Treasury will repay to the State an amount equal to 35 percent of the interest cost on any BABs issued during 2009 and 2010. The BAB subsidy payments from general obligation bonds are General Fund revenues to the State, while subsidy payments for lease-revenue bonds are deposited into a fund which is made available to the SPWB for any lawful purpose. In neither instance

A-11

are the subsidy payments specifically pledged to repayment of the BABs to which they relate. The cash subsidy payment with respect to the BABs, to which the State is entitled, is treated by the Internal Revenue Service as a refund of a tax credit and such refund may be offset by the Department of Treasury by any liability of the State payable to the federal government. None of the State’s BAB subsidy payments to date have been reduced because of such an offset.

Between April 2009 and December 2010, the State issued approximately $13.5 billion of BAB general obligation bonds and the SPWB issued $551 million of BAB lease-revenue bonds (of which $150 million have been redeemed). The remaining aggregate amount of the subsidy payments expected to be received from fiscal year 2017-18 through the maturity of these bonds (mostly 20 to 30 years from issuance) based on the 35 percent subsidy rate is approximately $6.6 billion for the general obligation BABs and $168.9 million for the SPWB lease-revenue BABs.

Pursuant to federal budget legislation, beginning on March 1, 2013, the federal government’s BAB subsidy payments were reduced as part of a “sequestration” of many program expenditures. The amount of the reduction of the BAB subsidy payment has been less than $30 million annually and is presently scheduled to continue until 2025, although U.S. Congress can terminate or modify it sooner, or extend it. None of the BAB subsidy payments are pledged to pay debt service for the general obligation and SPWB BABs, so this reduction will not affect the State’s ability to pay its debt service on time, nor have any material impact on the General Fund.

• Future Issuance Plans. The Proposed 2018 Budget assumes approximately $3.2 billion of new money general obligation bonds (some of which may initially be in the form of commercial paper notes) and approximately $707 million of lease-revenue bonds are expected to be issued in fiscal year 2018-19. These estimates will be updated by the State’s Treasurer’s Office based on information provided by the Department of Finance with respect to the updated funding needs of, and actual spending by, departments. In addition, the actual amount of bonds sold will depend on other factors such as overall budget constraints, market conditions and other considerations. The State also expects to issue refunding bonds as market conditions warrant.

The ratio of debt service on general obligation and lease-revenue bonds supported by the General Fund, to annual General Fund revenues and transfers (the “General Fund Debt Ratio”), can fluctuate as assumptions for future debt issuance and revenue projections are updated from time to time. Any changes to these assumptions will impact the projected General Fund Debt Ratio. Based on the revenue estimates contained in the Proposed 2018 Budget and bond issuance estimates referred to in the preceding paragraph, the General Fund Debt Ratio is estimated to equal approximately 6.3 percent in fiscal years 2017-18 and 2018-19.

The General Fund Debt Ratio is calculated based on the amount of debt service expected to be paid, without adjusting for receipts from the U.S. Treasury for the State’s current outstanding general obligation and lease-revenue BABs or the availability of any special funds that may be used to pay a portion of the debt service to help reduce General Fund costs. The total of these offsets is estimated at approximately $1.8 billion in each of fiscal years 2017-18 and 2018-19. Including the estimated offsets reduces the General Fund Debt Ratio to 4.8 percent in fiscal years 2017-18 and 2018-19. The actual General Fund Debt Ratio in future fiscal years will depend on a variety of factors, including actual debt issuance (which may include additional issuance approved in the future by the Legislature and, for general obligation bonds, the voters), actual interest rates, debt service structure, and actual General Fund revenues and transfers.

• Tobacco Settlement Revenue Bonds. In 1998, the State signed a settlement agreement (the “MSA”) with four major cigarette manufacturers (the “participating manufacturers”). Under the MSA, the participating manufacturers agreed to make payments to the State in perpetuity. Under a separate Memorandum of Understanding, half of the payments made by the cigarette manufacturers will be paid to the State and half to local governments, subject to certain adjustments.

In 2002, the State established a special purpose trust to purchase tobacco assets and to issue revenue bonds secured by the tobacco settlement revenues. Legislation in 2003 authorized a credit enhancement mechanism that

A-12

requires the Governor to request an appropriation from the General Fund in the annual Budget Act to pay debt service and other related costs in the event tobacco settlement revenues and certain other amounts are insufficient. The Legislature is not obligated to make any General Fund appropriation so requested.

The credit enhancement mechanism only applies to certain tobacco settlement bonds that were issued in 2005, 2013, 2015 and 2018 with an outstanding principal amount of approximately $2.2 billion (the “Enhanced Bonds”). The Enhanced Bonds are neither general nor legal obligations of the State or any of its political subdivisions and neither the faith and credit nor the taxing power nor any other assets or revenues of the State or any of its political subdivisions shall be pledged to the payment of the Enhanced Bonds. However, as described above, the State committed to request the Legislature for a General Fund appropriation in the event there are insufficient tobacco settlement revenues to pay debt service with respect to the Enhanced Bonds, and certain other available amounts, including the reserve fund for the Enhanced Bonds, are depleted. This appropriation has been requested and approved by the Legislature; however, the use of appropriated moneys has never been required.

Draws on the reserve funds for the Enhanced Bonds in the amount of approximately $7.9 million were used to make required debt service payments on the 2005 bonds in 2011 and 2012. In April 2013, the reserve fund was replenished in full from tobacco revenues. As of February 1, 2018, the balance of the reserve fund for the Enhanced Bonds was $152.5 million. If, in any future year, the tobacco settlement revenues are less than the required debt service payments on the Enhanced Bonds in such year, additional draws on the reserve funds will be required and at some point in the future the reserve funds may become fully depleted. The State is not obligated to replenish the reserve funds from the General Fund, or to request an appropriation to replenish the reserve funds.

• Office of Statewide Health Planning and Development Guarantees. The Office of Statewide Health Planning and Development of the State of California (“OSHPD”) insures loans and bond issues for the financing and refinancing of construction and renovation projects for nonprofit and publically-owned healthcare facilities. This program is currently authorized by statute to insure up to $3 billion for health facility projects.

State law established the Health Facility Construction Loan Insurance Fund (the “Fund”), which is used as a depository of fees and insurance premiums and any recoveries and is the initial source of funds used to pay administrative costs of the program and shortfalls resulting from defaults by insured borrowers. If the Fund is unable to make payment on an insured loan or bond, State law provides for the State Treasurer to issue debentures to the holders of the defaulted loan or bond which are payable on parity with State general obligation bonds. The Fund is liable for repayment to the General Fund of any money paid from the General Fund. All claims on insured loans to date have been paid from the Fund and no debentures have been issued.

As of December 31, 2017, OSHPD insured approximately 81 loans to nonprofit or publicly owned health facilities throughout California for approximately $1.5 billion, and a cash balance of approximately $162.3 million. The biennial actuarial study of the Fund as of June 30, 2014, was completed in July 2016 (the “2014 actuarial study”). Based upon a number of assumptions, the 2014 actuarial study concluded, among other things, that the Fund appeared to be sufficient under the “expected scenario” to maintain a positive balance until at least fiscal year 2043-44. Even under the “most pessimistic scenario,” the 2014 actuarial study found that there was a 70 percent likelihood that the Fund’s reserves as of June 30, 2014 would protect against any General Fund losses until at least fiscal year 2022-23, and a 90 percent likelihood that the Fund’s reserves as of June 30, 2014 would protect against any General Fund losses until at least fiscal year 2019-20. There can be no assurances that the financial condition of the Fund has not materially declined since the 2014 actuarial study.

In December 2016, OSHPD, the Department of Finance, and the State Treasurer entered into a memorandum of understanding that outlined the processes for the (i) issuance of debentures; (ii) payment of debentures from the General Fund should the Fund fail to pay the debentures; and (iii) repayment to the General Fund for any money paid for debentures.

• Cash Flow Borrowings. The majority of General Fund receipts are received in the latter part of the fiscal year. Disbursements from the General Fund occur more evenly throughout the fiscal year. The State’s cash management program customarily addresses this timing difference by making use of internal borrowing and by issuing short-term notes in the capital markets when necessary.

Internal Borrowing. The General Fund is currently authorized by law to borrow for cash management purposes from more than 700 of the State’s approximately 1,300 other funds in the State Treasury (the “Special Funds”). Total borrowing from Special Funds must be approved quarterly by the Pooled Money Investment Board (“PMIB”). The State Controller submits an authorization request to the PMIB quarterly, based on forecasted available funds and borrowing needs. The Legislature may from time to time adopt legislation establishing additional authority to borrow from Special Funds. As of the Proposed 2018 Budget, the General Fund is projected to have up to approximately $26 billion of internal funds (excluding the Budget Stabilization Account and the Special Fund for Economic Uncertainties) available during the remainder of fiscal year 2017-18 and at least $27 billion during fiscal year 2018-19. One fund from which moneys may be borrowed to provide additional cash resources to the General Fund is the BSA, which is currently funded at $8.5 billion and is projected to increase to $9.9 billion for most of fiscal year 2018-19 and to $13.5 billion at the end of fiscal year 2018-19. The State also may transfer funds into the General Fund from the SFEU, which is not a special fund.

External Borrowing. External borrowing is typically done with revenue anticipation notes (“RANs”) that are payable not later than the last day of the fiscal year in which they are issued. Prior to fiscal year 2015-16, RANs had been issued in all but one fiscal year since the mid-1980s and have always been paid at maturity. No RANs were issued in fiscal years 2015-16 or 2016-17 or are planned to be issued in fiscal years 2017-18 and 2018-19. The State also is authorized under certain circumstances to issue revenue anticipation warrants (“RAWs”) that are payable in the succeeding fiscal year. The State issued RAWs to bridge short-term cash management shortages in the early 1990s and early 2000s.

RANs and RAWs are both payable from any “Unapplied Money” in the General Fund on their maturity date, subject to the prior application of such money in the General Fund to pay Priority Payments. “Priority Payments” are payments as and when due to: (i) support the public school system and public institutions of higher education (as provided in Section 8 of Article XVI of the State Constitution); (ii) pay principal of and interest on general obligation bonds and general obligation commercial paper notes of the State; (iii) a contingent obligation for General Fund payments to local governments for certain costs for realigned public safety programs if not provided from a share of State sales and use taxes, as provided in Article XIII, Section 36 of the State Constitution, enacted by Proposition 30; (iv) provide reimbursement from the General Fund to any special fund or account to the extent such reimbursement is legally required to be made to repay borrowings therefrom pursuant to California Government Code Sections 16310 or 16418; and (v) pay State employees’ wages and benefits, State payments to pension and other State employee benefit trust funds, State Medi-Cal claims, lease payments to support lease revenue bonds, and any amounts determined by a court of competent jurisdiction to be required by federal law or the State Constitution to be paid with State warrants that can be cashed immediately.

The State’s cash position was strong entering the 2016-17 fiscal year, as the General Fund ended the previous year with internal loans of less than $1 billion. The State’s cash flow projections for fiscal year 2016-17 indicated that internal borrowings would be sufficient and available to meet the normal peaks and valleys of the State’s cash needs, while maintaining a cushion at all times of at least $2.5 billion. Accordingly, the State did not issue any RANs in fiscal year 2016-17, only the third time this has occurred since the commencement of annual RANs borrowings in the early 1980s. The State entered fiscal year 2017-18 with General Fund internal loans of $4.8 billion as of June 30, 2017. Cash flow projections for the balance of the fiscal year show no plan for a RAN borrowing to manage cash requirements, with an estimated cash cushion of unused internal borrowable resources of at least $17 billion at the end of each month. Taking into account intra-month cash flows, the State Controller’s Office projects that the State will have a cash cushion of at least $15 billion at any time during the remainder of fiscal year 2017-18 (including the availability of $8.5 billion in the BSA).

A-14

State fiscal officers constantly monitor the State’s cash position and if it appears that cash resources may become inadequate (including the maintenance of a projected cash reserve of at least $2.5 billion at any time), they will consider the use of other cash management techniques, including seeking additional legislation.

• Retirement Liabilities. The two main State pension funds, CalPERS and CalSTRS, each face unfunded future liabilities in the tens of billions of dollars. General Fund pension contributions to CalPERS and CalSTRS were estimated to be approximately $3.4 billion and $2.8 billion, respectively, for fiscal year 2017-18. The State also made a one-time $6 billion supplemental pension payment to CalPERS for fiscal year 2017-18. For fiscal year 2018-19, the contributions to CalPERS and CalSTRS are estimated to be approximately $3.6 billion and $3.1 billion, respectively. The State also has significant unfunded liability with respect to other postemployment benefits (“OPEB”). Strategies to prefund these costs were established in 2015, and today, nearly all State employees now contribute towards prefunding OPEB costs.

If the State does not take action concerning these liabilities soon, the extra costs needed to retire these unfunded liabilities over the next few decades will likely increase dramatically. Lower than expected investment returns have been a primary reason for the growth of unfunded pension liabilities in the last decade. There has also been benefit increases that are implemented retroactively, and demographic and pay changes among employees and retirees. In addition, the State has very little flexibility under case law to alter benefit and funding arrangements for current employees. Generally, pension benefit packages, once promised to an employee, cannot be reduced, either retrospectively or prospectively. There can be no assurance that the State’s annual required contributions to CalPERS and CalSTRS will not significantly increase in the future. Recent legislation with respect to both CalPERS and CalSTRS and changes in actuarial assumptions and funding methodologies are expected to result in significant annual increases in the amount the State is required to pay from the General Fund for the foreseeable future. The actual amount of any increase will depend on a variety of factors, including, but not limited to, investment returns, actuarial assumptions, experience and retirement benefit adjustments. In addition, governments typically do not “pre-fund” their retiree health liabilities. This means that future taxpayers may bear a larger cost burden for these benefits. Unlike pensions, there are no investment returns under this type of funding structure to cover a large portion of benefit costs.

• Health Care Reform. California continues implementation of the federal Affordable Care Act (the “ACA”). Medi-Cal, California’s Medicaid program, is a health care entitlement program for low-income individuals and families who receive public assistance or otherwise lack health care coverage. Medi-Cal serves approximately 34 percent of all Californians. The mandatory Medi-Cal expansion simplified eligibility, enrollment, and retention rules that make it easier to get and stay on Medi-Cal. Additionally, the optional expansion of Medi-Cal extended eligibility to adults without children, and to parent and caretaker relatives with incomes up to 138 percent of the federal poverty level.

The 2018 Governor’s Budget estimates that in fiscal year 2018-19, approximately 3.9 million Californians will have health insurance through the optional expansion of Medi-Cal, and 1.4 million through the State’s insurance exchange (Covered California). The 2018 Governor’s Budget includes costs of $22.9 billion ($1.6 billion General Fund) in fiscal year 2018-19 for the optional expansion. The federal government paid nearly 100 percent of the costs of this expansion for fiscal years 2013-14 through 2015-16. As of January 1, 2018, California is responsible for 6 percent of these costs, with California’s contribution gradually increasing each fiscal year until fiscal year 2020-21, when the State will pay 10 percent of the total costs. By fiscal year 2020-21, the General Fund share for the optional expansion is projected to be $2.5 billion.

In 2017, U.S. Congress attempted several times to repeal the ACA, which would drop health care coverage for millions of Californians. Such actions, if successful, may cost the General Fund tens of billions dollars annually and potentially more than double the cost of Medi-Cal. While these recent efforts were defeated, U.S. Congress continues to indicate a willingness to shift health care and other entitlement program costs from the federal budget to states to address recent increases in the federal deficit.

Litigation

The State is a party to numerous legal proceedings, many of which normally occur in governmental operations. In addition, the State is involved in certain other legal proceedings (described in California’s recent financial statements) that, if decided against the State might require the State to make significant future expenditures or substantially impair future revenue sources. Because of the prospective nature of these proceedings, it is not presently possible to predict the outcome of such litigation, estimate the potential impact on the ability of the State to pay debt service costs on its obligations, or determine what impact, if any, such proceedings may have on the Fund.

USE OF PROCEEDS

The net proceeds from the issuance of Common Shares hereunder will be invested in accordance with the Fund’s investment objectives and policies as stated below. Pending investment, the timing of which may vary depending on the size of the investment but in no case is expected to exceed 30 days, it is anticipated that the proceeds will be invested in high-quality, short-term investments.

INVESTMENT RESTRICTIONS

Except as described below, the Fund, as a fundamental policy, may not, without the approval of the holders of a “majority of the outstanding” Common Shares and preferred shares, including the Fund’s outstanding Variable Rate Demand Preferred Shares (referred to herein as “VRDP Shares”) and its outstanding MuniFund Preferred Shares (referred to herein as “MFP Shares”) (collectively, “Preferred Shares”), voting together as a single class, and of the holders of a majority of the outstanding Preferred Shares voting as a separate class:

(1) Issue senior securities, as defined in the 1940 Act, other than Preferred Shares, except to the extent permitted under the 1940 Act and except to the extent such issuance might be involved with respect to borrowings described under subparagraph (2) below;¹

(2) Borrow money, except from banks for temporary or emergency purposes or for repurchase of its shares, and then only in an amount not exceeding one-third of the value of the Fund’s total assets (including the amount borrowed) less the Fund’s liabilities (other than borrowings);^1,²

(3) Act as underwriter of another issuer’s securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933, as amended (the “1933 Act”) in connection with the purchase and sale of portfolio securities;

(4) Invest more than 25% of its total assets in securities of issuers in any one industry; provided, however, that such limitation shall not apply to municipal bonds other than those municipal bonds backed only by the assets and revenues of non-governmental users;³

(5) Purchase or sell real estate, but this shall not prevent the Fund from investing in municipal bonds secured by real estate or interests therein or foreclosing upon and selling such security;

(6) Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from purchasing or selling options, futures contracts, derivative instruments or from investing in securities or other instruments backed by physical commodities);

(7) Make loans, except as permitted by the 1940 Act, and exemptive orders granted under the 1940 Act; and;⁴

Section 18(c) of the 1940 Act generally limits a registered closed-end investment company to issuing one class of senior securities representing indebtedness and one class of senior securities representing stock, except that the class of indebtedness or stock may be issued in one or more series, and promissory notes or other evidences of indebtedness issued in consideration of any loan, extension, or renewal thereof, made by a bank or other person and privately arranged, and not intended to be publicly distributed, are not deemed a separate class of senior securities.

²	Section 18(a) of the 1940 Act generally prohibits a registered closed-end fund from incurring borrowings if, immediately thereafter, the aggregate amount of its borrowings exceeds 33¹/₃% of its total assets.

³	For purposes of this restriction, governments and their political subdivisions are not members of any industry.

⁴

Section 21 of the 1940 Act makes it unlawful for a registered investment company, like the Fund, to lend money or other property if (i) the investment company’s policies set forth in its registration statement do not permit such a loan or (ii) the borrower controls or is under common control with the investment company. The Fund has not applied for, and currently does not intend to apply for, any exemptive relief that would allow it to make loans outside of the limits of the 1940 Act.

(8) Purchase any securities (other than obligations issued or guaranteed by the United States Government or by its agencies or instrumentalities), if as a result more than 5% of the Fund’s total assets would then be invested in securities of a single issuer or if as a result the Fund would hold more than 10% of the outstanding voting securities of any single issuer; provided that, with respect to 50% of the Fund’s assets, the Fund may invest up to 25% of its assets in the securities of any one issuer.

For purposes of the foregoing, “majority of the outstanding,” when used with respect to particular shares of the Fund, means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less.

For the purpose of applying the limitation set forth in subparagraph (1) above, the Fund may not issue senior securities not permitted by the 1940 Act simply by describing such securities in the Prospectus.

For the purpose of applying the 25% industry limitation set forth in subparagraph (4) above, such limitation will apply to tax-exempt municipal securities if the payment of principal and interest for such securities is derived principally from a specific project associated with an issuer that is not a governmental entity or a political subdivision of a government, and in that situation the Fund will consider such municipal securities to be in an industry associated with the project.

For the purpose of applying the limitation set forth in subparagraph (8) above, an issuer shall be deemed the sole issuer of a security when its assets and revenues are separate from other governmental entities and its securities are backed only by its assets and revenues. Similarly, in the case of a non-governmental issuer, such as an industrial corporation or a privately owned or operated hospital, if the security is backed only by the assets and revenues of the non-governmental issuer, then such non-governmental issuer would be deemed to be the sole issuer. Where a security is also backed by the enforceable obligation of a superior or unrelated governmental or other entity (other than a bond insurer), it shall also be included in the computation of securities owned that are issued by such governmental or other entity. Where a security is guaranteed by a governmental entity or some other facility, such as a bank guarantee or letter of credit, such a guarantee or letter of credit would be considered a separate security and would be treated as an issue of such government, other entity or bank. When a municipal bond is insured by bond insurance, it shall not be considered a security that is issued or guaranteed by the insurer; instead, the issuer of such municipal bond will be determined in accordance with the principles set forth above. The foregoing restrictions do not limit the percentage of the Fund’s assets that may be invested in municipal securities insured by any given insurer.

The Fund is diversified for purposes of the 1940 Act. Consequently, as to 75% of the Fund’s total assets, the Fund may not (1) purchase the securities of any one issuer (other than cash, securities of other investment companies and securities issued by the U.S. government or its agencies or instrumentalities) if immediately after such purchase, more than 5% of the value of the Fund’s total assets would be invested in securities of such issuer or (2) purchase more than 10% of the outstanding voting securities of such issuer.

Subject to certain exemptions, under the 1940 Act, the Fund may invest only up to 10% of its total assets in the aggregate in shares of other investment companies and only up to 5% of its total assets in any one investment company, provided the investment does not represent more than 3% of the voting stock of the acquired investment company at the time such shares are purchased. As a shareholder of any investment company, the Fund will bear its ratable share of that investment company’s expenses, and will remain subject to payment of the Fund’s management, advisory and administrative fees with respect to assets so invested. Holders of Common Shares (“Common Shareholders”) would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to leverage risks. The Fund will consider the investments of underlying investment companies when determining compliance with Rule 35d-1 under the 1940 Act. Moreover, the Fund will consider the investments of underlying investment companies when determining compliance with its own concentration policy, to the extent the Fund has sufficient information about such investments.

In addition to the foregoing fundamental investment policies, the Fund is also subject to the following non-fundamental restrictions and policies, which may be changed by the Fund’s Board of Trustees (the “Board”). The Fund may not:

(1) Sell securities short, unless the Fund owns or has the right to obtain securities equivalent in kind and amount to the securities sold, at no added cost, and provided that transactions in options, futures contracts, options on futures contracts, or other derivative instruments are not deemed to constitute selling securities short.

(2) Invest more than 10% of its total assets in securities of other open- or closed- end investment companies (including exchange-traded funds (“ETFs”)), except in compliance with the 1940 Act and any exemptive relief obtained thereunder.

(3) Enter into futures contracts or related options or forward contracts, if more than 30% of the Fund’s net assets (total assets less liabilities) would be represented by futures contracts or more than 5% of the Fund’s net assets would be committed to initial margin deposits and premiums on futures contracts and related options.

(4) Purchase securities when borrowings exceed 5% of its total assets if and so long as Preferred Shares are outstanding.

(5) Purchase securities of companies for the purpose of exercising control, except that the Fund may invest up to 5% of its net assets in tax-exempt or taxable fixed-income securities or equity securities for the purpose of acquiring control of an issuer whose municipal bonds (a) the Fund already owns and (b) have deteriorated or are expected shortly to deteriorate significantly in credit quality, provided the Fund’s sub-adviser, Nuveen Asset Management, LLC (“Nuveen Asset Management”) determines that such investment should enable the Fund to better maximize the value of its existing investment in such issuer.

The restrictions and other limitations set forth above will apply only at the time of purchase of securities and will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of an acquisition of securities.

The Fund may be subject to certain restrictions imposed by either guidelines of one or more nationally recognized statistical rating organizations (“NRSROs”) that may issue ratings for Preferred Shares, or, if issued, commercial paper or notes, or, if the Fund borrows from a lender, by the lender. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. If these restrictions were to apply, it is not anticipated that these covenants or guidelines would impede the Funds investment adviser, Nuveen Fund Advisors, LLC (“NFALLC”) from managing the Fund’s portfolio in accordance with the Fund’s investment objectives and policies.

At least six months prior to the scheduled redemption of all of the Fund’s outstanding Variable Rate Demand Preferred Shares (referred to herein as “VRDP Shares”) in 2040, the Fund will maintain segregated assets rated at least investment grade (and including deposit securities, including, but not limited to, cash or cash equivalents, U.S. government securities, highly rated municipal obligations or money market funds, in an amount equal to 20% of segregated assets, with 135 days remaining to the redemption date, increasing to 100% with 15 days remaining) with a market value equal to at least 110% of the liquidation preference of all outstanding VRDP Shares until the redemption of all such outstanding VRDP Shares.

At least six months prior to the scheduled redemption of all outstanding MFP Shares in 2047, the Fund will earmark assets rated at least A- or the equivalent (and including deposit securities, including, but not limited to, cash or cash equivalents, U.S. government securities, highly rated municipal obligations or money market funds, in an amount equal to 20% of segregated assets, with 135 days remaining to the redemption date, increasing to 100% with 15 days remaining) with a market value equal to at least 110% of all outstanding MFP Shares until the redemption of all such outstanding MFP Shares.

INVESTMENT POLICIES AND TECHNIQUES

The following information supplements the discussion of the Fund’s investment objectives, policies, and techniques that are described in the Prospectus.

INVESTMENT PHILOSOPHY AND PROCESS

INVESTMENT PHILOSOPHY. Nuveen Asset Management believes that the unique tax treatment of municipal securities and the structural characteristics in the municipal securities market create attractive opportunities to enhance the after-tax total return and diversification of the investment portfolios of taxable investors. Nuveen Asset Management believes that these unique characteristics also present unique risks that may be managed to realize the benefits of the asset class.

After-Tax Income Potential: The primary source of total return from municipal securities comes from the tax-exempt income derived therefrom. Nuveen Asset Management believes that, at acceptable levels of credit risk and maturity principal risk, the municipal securities market offers the potential for higher after-tax income when compared with other fixed income markets.

Managing Multi-Faceted Risks: Risk in the municipal securities market is derived from multiple sources, including credit risk at the issuer and sector levels, structural risks such as call risk, yield curve risk, and legislative and tax-related risks. Nuveen Asset Management believes that managing these risks at both the individual security and Fund portfolio levels is an important element of realizing the after-tax income and total return potential of the asset class.

Market Inefficiencies: Nuveen Asset Management believes that the scale and intricacy of the municipal securities market often results in pricing anomalies and other inefficiencies that can be identified and capitalized on through trading strategies.

INVESTMENT PROCESS. Nuveen Asset Management believes that a bottom-up, value-oriented investment strategy that seeks to identify underrated and undervalued securities and sectors is positioned to capture the opportunities inherent in the municipal securities market and potentially outperform the general municipal securities market over time. The primary elements of Nuveen Asset Management’s investment process are:

Credit Analysis and Surveillance: Nuveen Asset Management focuses on bottom-up, fundamental analysis of municipal securities issuers. Analysts screen each sector for issuers that meet the fundamental tests of creditworthiness and favor those securities with demonstrable growth potential, solid coverage of debt service and a priority lien on hard assets, dedicated revenue streams or tax resources. As part of Nuveen Asset Management’s overall risk management process, analysts actively monitor the credit quality of portfolio holdings.

Sector Analysis: Organized by sector, analysts continually assess the key issues and trends affecting each sector in order to maintain a sector outlook. Evaluating such factors as historical default rates and average credit spreads within each sector, analysts provide top-down analysis that supports decisions to overweight or underweight a given sector in a portfolio.

Trading Strategies: Through its trading strategies, Nuveen Asset Management seeks to enhance portfolio value by trading to take advantage of inefficiencies found in the municipal market. This may entail selling issues Nuveen Asset Management deems to be overvalued and purchasing issues Nuveen Asset Management considers to be undervalued.

Sell Discipline: Nuveen Asset Management generally sells securities when it (i) determines a security has become overvalued or over-rated, (ii) identifies credit deterioration, or (iii) modifies a portfolio strategy, such as sector allocation. Nuveen Asset Management may also sell securities when such securities exceed the portfolio’s diversification targets.

INVESTMENT POLICIES

The Fund’s investment objectives are:

•

to provide current income exempt from regular federal income tax, the federal alternative minimum tax applicable to individuals and California income tax; and

•

There can be no assurance that the Fund will achieve its investment objectives.

Underrated municipal securities are those whose ratings do not, in Nuveen Asset Management’s opinion, reflect their true value. Municipal securities may be underrated because of the time that has elapsed since their rating was assigned or reviewed, or because of positive factors that may not have been fully taken into account by rating agencies, or for other similar reasons. Municipal securities that are undervalued or that represent undervalued municipal market sectors are municipal securities that, in Nuveen Asset Management’s opinion, are worth more than the value assigned to them in the marketplace. Municipal securities of particular types or purposes (e.g., hospital bonds, industrial revenue bonds or bonds issued by a particular municipal issuer) may be undervalued because there is a temporary excess of supply in that market sector, or because of a general decline in the market price of municipal securities of the market sector for reasons that do not apply to the particular municipal securities that are considered undervalued. The Fund’s investment in underrated or undervalued municipal securities will be based on Nuveen Asset Management’s belief that the prices of such municipal securities should ultimately reflect their true value. Accordingly, “enhancement of portfolio value relative to the California municipal bond market” refers to the Fund’s objective of attempting to realize above-average capital appreciation in a rising market, and to experience less than average capital losses in a declining market. Thus, the Fund’s secondary investment objective is not intended to suggest that capital appreciation is itself an objective of the Fund. Instead, the Fund seeks enhancement of portfolio value relative to the California municipal bond market by prudent selection of California municipal securities, regardless of which direction the market may move. Any capital appreciation realized by the Fund will generally result in the distribution of taxable capital gains to Common Shareholders and Preferred Shareholders. The Fund is currently required to allocate net capital gains and other income taxable for federal income tax purposes, if any, proportionately between Common Shares and Preferred Shares and dividends paid on Preferred Shares during specified rate periods will include an allocated portion of any such net capital gains and other taxable income. See “Tax Matters” and “Description Shares—VRDP Shares.”

It is a fundamental policy that, under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes (“Assets”), in municipal securities and other related investments, the income from which is exempt from regular federal and California income tax. For purposes of calculating net assets, the Fund will value eligible derivatives at market value or fair value instead of notional value. As a non-fundamental policy which may be changed by the Fund’s trustees without shareholder notice, the Fund invests 100% of its Managed Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase. As a non-fundamental policy subject to change by the Fund’s trustees upon 60 days’ notice to shareholders, the Fund invests at least 80% of its Assets in municipal securities and other related investments the income from which is exempt from the federal alternative minimum tax applicable to individuals at the time of purchase.

As a non-fundamental policy subject to change by the Fund’s Board upon 60 days’ notice to the shareholders, under normal circumstances, the Fund invests at least 80% of its Managed Assets in investment grade securities that, at the time of investment, are rated within the four highest grades (Baa or BBB or better) by at least one of the NRSROs that rate such security or are unrated but judged to be of comparable quality by Nuveen Asset Management. Also, as a non-fundamental policy, the Fund may invest up to 20% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade or are unrated but judged to be of comparable quality by Nuveen Asset Management. Additionally, as a non-fundamental policy, no more than 10% of the Fund’s Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Asset Management. The Fund may invest in distressed securities. The Fund may not invest in the securities of an issuer which, at the time of investment, is in default on its obligations to pay principal or interest thereon when due or that is involved in a bankruptcy proceeding (i.e., rated below C-, at the time of investment); provided, however, that Nuveen Asset Management may determine that it is in the best interest of shareholders in pursuing a workout arrangement with issuers of defaulted securities to make loans to the defaulted issuer or another party, or purchase a debt, equity or other interest from the defaulted issuer or another party, or take other related or similar steps involving the investment of additional monies, but only if that issuer’s securities are already held by the Fund. The Fund may invest up to 15% of its Managed Assets in inverse floating rate securities. The economic effect of leverage through the Fund’s purchase of inverse floating rate securities creates an opportunity for increased net income and returns, but also creates the possibly that the Fund’s long-term returns will be diminished if the cost of leverage exceeds the return on the inverse floating rate securities purchased by the Fund.

maturity, coupon and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same yield.

The Fund may invest in distressed securities which are securities issued by companies that may be experiencing financial difficulties, such as being in default on their obligations to pay principal or interest thereon when due or that are involved in bankruptcy or insolvency proceedings. The issuers of such securities may be in transition, out of favor, financially leveraged or troubled, or potentially troubled, and may be or have recently been involved in major strategic actions, restructurings, bankruptcy, reorganization or liquidation. These characteristics of these issuers can cause their securities to be particularly risky, although they also may offer the potential for high returns. These issuers’ securities may be considered speculative, and the ability of the issuers to pay their debts on schedule could be affected by adverse interest rate movements, changes in the general economic climate, economic factors affecting a particular industry or specific developments within the issuers. Distressed securities frequently do not produce income while they are outstanding and may require the Fund to bear certain extraordinary expenses in order to protect and recover its investment.

The foregoing credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a NRSRO downgrades its assessment of the credit characteristics of a particular issuer or that valuation changes of various bonds cause the Fund’s portfolio to fail to satisfy those policies. In determining whether to retain or sell such a security, NFALLC and/or Nuveen Asset Management may consider such factors as their assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. See “—Municipal Securities.” The Fund may also invest in securities of other open- or closed-end investment companies that invest primarily in municipal bonds of the types in which the Fund may invest directly. See “—Other Investment Companies.”

The Fund will generally invest in California municipal securities with intermediate or long-term maturities. Generally, the Fund is expected to have an average effective maturity of 15 to 30 years, but the average effective maturity of obligations held by the Fund may be shortened or lengthened, depending on market conditions and on an assessment by the Fund’s portfolio manager of which segments of the municipal securities market offer the most favorable relative investment values and opportunities for tax-exempt income and total return. As of March 31, 2018, the effective maturity of the Fund’s portfolio was 22.48 years. As a result, the Fund’s portfolio at any given time may include both long-term and intermediate-term California municipal securities. Moreover, during temporary defensive periods (e.g., times when, in NFALLC’s opinion, temporary imbalances of supply and demand or other temporary dislocations in the tax-exempt bond market adversely affect the price at which long-term or intermediate-term municipal securities are available), and in order to help keep the Fund’s assets fully invested, the Fund may invest any percentage of its net assets in short-term investments including high quality, short-term debt securities that may be either tax-exempt or taxable. The Fund will generally select obligations which may not be redeemed at the option of the issuer for approximately seven to nine years.

The Fund may purchase municipal securities that are additionally secured by insurance, bank credit agreements, or escrow accounts. The credit quality of companies which provide such credit enhancements may affect the value of those securities. Although the insurance feature may reduce certain financial risks, the premiums for insurance and the higher market price paid for insured obligations may reduce the Fund’s income. The insurance feature guarantees only the payment of principal and interest on the obligation when due and does not guarantee the market value of the insured obligations, which will fluctuate with the bond market and the financial success of the issuer and the insurer, and the effectiveness and value of the insurance itself is dependent on the continued creditworthiness of the insurer. No representation is made as to the insurers’ ability to meet their commitments.

legislatures or referenda extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon municipalities to levy taxes. There is also the possibility that, as a result of legislation or other conditions, the power or ability of any issuer to pay, when due, the principal of and interest on its municipal securities may be materially affected.

The Fund cannot change its investment objectives without the approval of the holders of a “majority of the outstanding” Common Shares and Preferred Shares, voting together as a single class, and of the holders of a “majority of the outstanding” Preferred Shares, voting as a separate class. When used with respect to particular shares of the Fund, a “majority of the outstanding” shares under the 1940 Act, means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less. See “Description of Shares—Preferred Shares—Voting Rights” for additional information with respect to the voting rights of Fund shareholders.

As of March 31, 2018, approximately 87% of the Fund’s Managed Assets were invested in municipal securities rated investment grade. The relative percentages of the value of the investments attributable to investment grade municipal securities and to below investment grade municipal securities could change over time as a result of rebalancing the Fund’s assets by Nuveen Asset Management, market value fluctuations, issuance of additional shares and other events.

MUNICIPAL SECURITIES

General. The Fund may invest in various municipal securities, including municipal bonds and notes, other securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular federal income tax, the federal alternative minimum tax applicable to individuals and California income tax. Municipal securities are often issued by state and local governmental entities to finance or refinance public projects such as roads, schools, and water supply systems. Municipal securities may also be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility and pollution control projects. Municipal securities may be issued on a long-term basis to provide permanent financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments and mortgage payments. Municipal securities may also be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. The Fund may purchase municipal securities in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms including fixed coupon, variable rate, zero coupon, capital appreciation bonds, tender option bonds, and residual interest bonds or inverse floating rate securities; or acquired through investments in pooled vehicles, partnerships or other investment companies. Inverse floating rate securities are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and represent a leveraged investment in an underlying municipal security, which could have the economic effect of leverage.

Tobacco Settlement Bonds. Included in the general category of municipal securities described in the Prospectus are “tobacco settlement bonds.” The Fund may invest in tobacco settlement bonds, which are municipal securities that are backed solely by expected revenues to be derived from lawsuits involving tobacco related deaths and illnesses which were settled between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state’s proportionate share in the Master Settlement Agreement (“MSA”). The MSA is an agreement, reached out of court in November 1998 between 46 states and nearly all of the U.S. tobacco manufacturers. The MSA provides for annual payments in perpetuity by the manufacturers to the states in exchange for releasing all claims against the manufacturers and a pledge of no further litigation. Tobacco manufacturers pay into a master escrow trust based on their market share, and each state receives a fixed percentage of the payment as set forth in the MSA. A number of states have securitized the future flow of

those payments by selling bonds pursuant to indentures or through distinct governmental entities created for such purpose. The principal and interest payments on the bonds are backed by the future revenue flow related to the MSA. Annual payments on the bonds, and thus risk to the Fund, are highly dependent on the receipt of future settlement payments to the state or its governmental entity.

The actual amount of future settlement payments is further dependent on many factors, including, but not limited to, annual domestic cigarette shipments, reduced cigarette consumption, increased taxes on cigarettes, inflation, financial capability of tobacco companies, continuing litigation and the possibility of tobacco manufacturer bankruptcy. The initial and annual payments made by the tobacco companies will be adjusted based on a number of factors, the most important of which is domestic cigarette consumption. If the volume of cigarettes shipped in the U.S. by manufacturers participating in the settlement decreases significantly, payments due from them will also decrease. Demand for cigarettes in the U.S. could continue to decline due to price increases needed to recoup the cost of payments by tobacco companies. Demand could also be affected by: anti-smoking campaigns, tax increases, reduced advertising, enforcement of laws prohibiting sales to minors; elimination of certain sales venues such as vending machines; and the spread of local ordinances restricting smoking in public places. As a result, payments made by tobacco manufacturers could be negatively impacted if the decrease in tobacco consumption is significantly greater than the forecasted decline. A market share loss by the MSA companies to non-MSA participating tobacco manufacturers would cause a downward adjustment in the payment amounts. A participating manufacturer filing for bankruptcy also could cause delays or reductions in bond payments. The MSA itself has been subject to legal challenges and has, to date, withstood those challenges.

Municipal Leases and Certificates of Participation. Also included within the general category of municipal securities described in the Prospectus are municipal leases, certificates of participation in such lease obligations or installment purchase contract obligations (hereinafter collectively called “Municipal Lease Obligations”) of municipal authorities or entities. Although a Municipal Lease Obligation does not constitute a general obligation of the municipality for which the municipality’s taxing power is pledged, a Municipal Lease Obligation is ordinarily backed by the municipality’s covenant to budget for, appropriate and make the payments due under the Municipal Lease Obligation. However, certain Municipal Lease Obligations contain “non-appropriation” clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In the case of a “non-appropriation” lease, the Fund’s ability to recover under the lease in the event of non-appropriation or default will be limited solely to the repossession of the leased property, without recourse to the general credit of the lessee, and disposition or releasing of the property might prove difficult. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. In order to reduce this risk, the Fund will only purchase Municipal Lease Obligations where Nuveen Asset Management believes the issuer has a strong incentive to continue making appropriations until maturity.

financing generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer’s payment obligations under the notes or that refinancing will be otherwise unavailable.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure development to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

HEDGING STRATEGIES AND OTHER USES OF DERIVATIVES

The Fund may periodically engage in hedging transactions, and otherwise use various types of derivative instruments, described below, to reduce risk, to effectively gain particular market exposures, to seek to enhance returns, and to reduce transaction costs, among other reasons.

“Hedging” is a term used for various methods of seeking to preserve portfolio capital value by offsetting price changes in one investment through making another investment whose price should tend to move in the opposite direction.

A “derivative” is a financial contract whose value is based on (or “derived” from) a traditional security (such as a stock or a bond), an asset (such as a commodity like gold), or a market index (such as the Lehman Municipal Bond Index). Some forms of derivatives may trade on exchanges, while non-standardized derivatives, which tend to be more specialized and complex, trade in “over-the-counter” or a one-on-one basis. It may be

desirable and possible in various market environments to partially hedge the portfolio against fluctuations in market value due to market interest rate or credit quality fluctuations, or instead to gain a desired investment exposure, by entering into various types of derivative transactions, including financial futures and index futures as well as related put and call options on such instruments, structured notes, or interest rate swaps on taxable or tax-exempt securities or indexes (which may be “forward-starting”), credit default swaps, and options on interest rate swaps, among others.

These transactions present certain risks. In particular, the imperfect correlation between price movements in the futures contract and price movements in the securities being hedged creates the possibility that losses on the hedge by the Fund may be greater than gains in the value of the securities in the Fund’s portfolio. In addition, futures and options markets may not be liquid in all circumstances. As a result, in volatile markets, the Fund may not be able to close out the transaction without incurring losses substantially greater than the initial deposit. Finally, the potential deposit requirements in futures contracts create an ongoing greater potential financial risk than do options transactions, where the exposure is limited to the cost of the initial premium. Losses due to hedging transactions will reduce yield. Net gains, if any, from hedging and other portfolio transactions will be distributed as taxable distributions to shareholders. Successful implementation of most hedging strategies will generate taxable income.

The Fund will invest in these instruments only in markets believed by Nuveen Asset Management to be active and sufficiently liquid. Successful implementation of most hedging strategies will generate taxable income.

The Fund may enter into swap transactions for any purpose consistent with its investment objective, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, as a duration management technique, to reduce risk arising from the ownership of a particular instrument, or to gain exposure to certain sectors or markets in the most economical way possible.

Some, but not all, swaps may be cleared, in which case a central clearing counterparty stands between each buyer and seller and effectively guarantees performance of each contract, to the extent of its available resources for such purpose. Uncleared swaps have no such protection; each party bears the risk that its direct counterparty will default.

fixed rate and a floating rate) applied to a specified notional amount. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate floor. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index rises above a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate cap. Interest rate collars involve selling a cap and purchasing a floor or vice versa to protect the Fund against interest rate movements exceeding given minimum or maximum levels.

Depending on the state of interest rates in general, the Fund’s use of interest rate swaps could enhance or harm the overall performance of Common Shares. To the extent interest rates decline, the value of the interest rate swap could decline, and could result in a decline in the net asset value (“NAV”) of Common Shares. In addition, if the counterparty to an interest rate swap defaults, the Fund would not be able to use the anticipated net receipts under the swap to offset the interest payments on borrowings or the dividend payments on any outstanding preferred shares. Depending on whether the Fund would be entitled to receive net payments from the counterparty on the swap, which in turn would depend on the general state of short-term interest rates at that point in time, such a default could negatively impact the performance of Common Shares. In addition, at the time an interest rate swap transaction reaches its scheduled termination date, there is a risk that the Fund would not be able to obtain a replacement transaction or that the terms of the replacement would not be as favorable as on the expiring transaction. If this occurs, it could have a negative impact on the performance of Common Shares. The Fund could be required to prepay the principal amount of any borrowings. Such redemption or prepayment would likely result in the Fund seeking to terminate early all or a portion of any swap transaction. Early termination of a swap could result in a termination payment by or to the Fund.

Total Return Swaps. In a total return swap, one party agrees to pay the other the “total return” of a defined underlying asset during a specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A total return swap may be applied to any underlying asset but is most commonly used with equity indices, single stocks, bonds and defined baskets of loans and mortgages. The Fund might enter into a total return swap involving an underlying index or basket of securities to create exposure to a potentially widely-diversified range of securities in a single trade. An index total return swap can be used by Nuveen Asset Management to assume risk, without the complications of buying the component securities from what may not always be the most liquid of markets.

Credit Default Swaps. A credit default swap is a bilateral contract that enables an investor to buy or sell protection against a defined-issuer credit event. The Fund may enter into credit default swap agreements either as a buyer or a seller. The Fund may buy protection to attempt to mitigate the risk of default or credit quality deterioration in an individual security or a segment of the fixed income securities market to which it has exposure, or to take a “short” position in individual bonds or market segments which it does not own. The Fund may sell protection in an attempt to gain exposure to the credit quality characteristics of particular bonds or market segments without investing directly in those bonds or market segments.

As the buyer of protection in a credit default swap, the Fund would pay a premium (by means of an upfront payment or a periodic stream of payments over the term of the agreement) in return for the right to deliver a referenced bond or group of bonds to the protection seller and receive the full notional or par value (or other agreed upon value) upon a default (or similar event) by the issuer(s) of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Fund. Thus, the cost to the Fund would be the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Fund bears the risk that the protection seller may fail to satisfy its payment obligations.

event occurs, however, generally the Fund would have to pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. As the protection seller, the Fund effectively adds the economic equivalent of leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. Thus, the Fund bears the same risk as it would by buying the reference obligations directly, plus the additional risks related to obtaining investment exposure through a derivative instrument discussed below under “—Risks Associated with Swap Transactions.”

Swap Options. A swap option is a contract that gives a counterparty the right (but not the obligation), in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement at some designated future time on specified terms. A cash-settled option on a swap gives the purchaser the right, in return for the premium paid, to receive an amount of cash equal to the value of the underlying swap as of the exercise date. The Fund may write (sell) and purchase put and call swap options. Depending on the terms of the particular option agreement, the Fund generally would incur a greater degree of risk when it writes a swap option than when it purchases a swap option. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swap option, upon exercise of the option the Fund would become obligated according to the terms of the underlying agreement.

Risks Associated with Swap Transactions. The use of swap transactions is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions. If Nuveen Asset Management is incorrect in its forecasts of default risks, market spreads or other applicable factors or events, the investment performance of the Fund would diminish compared with what it would have been if these techniques were not used. As the protection seller in a credit default swap, the Fund effectively adds the economic equivalent of leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. The Fund generally may only close out a swap, cap, floor, collar or other two-party contract with its particular counterparty, and generally may only transfer a position with the consent of that counterparty. In addition, the price at which the Fund may close out such a two party contract may not correlate with the price change in the underlying reference asset. If the counterparty defaults, the Fund will have contractual remedies, but there can be no assurance that the counterparty will be able to meet its contractual obligations or that the Fund will succeed in enforcing its rights.

It also is possible that developments in the derivatives market, including changes in government regulation, could adversely affect the Fund’s ability to terminate existing swap or other agreements or to realize amounts to be received under such agreements.

Futures and Options on Futures. The Fund may attempt to hedge all or a portion of its investment portfolio against market risk by engaging in transactions in financial futures contracts, options on financial futures or options that either are based on an index of long-term municipal securities (i.e., those with average remaining maturities of more than 15 years) or relate to debt securities whose prices Nuveen Asset Management anticipates to correlate with the prices of the municipal securities the Fund owns. To accomplish such hedging, the Fund may take an investment position in a futures contract or in an option which is expected to move in the opposite direction from the position being hedged. Hedging may be utilized to reduce the risk that the value of securities the Fund owns may decline on account of an increase in interest rates and to hedge against increases in the cost of the securities the Fund intends to purchase as a result of a decline in interest rates. The use of futures and options for hedging purposes can be expected to result in taxable income or gain. The Fund currently intends to allocate any taxable income or gain proportionately between its common shares and its Preferred Shares. See “Tax Matters.” If futures are used for hedging purposes, there can be no guarantee that there will be a correlation between price movements in the futures contract and in the underlying financial instruments that are being hedged. This could result from differences between the financial instruments being hedged and the financial instruments underlying the standard contracts available for trading (e.g., differences in interest rate levels,

maturities and the creditworthiness of issuers) among other factors. In addition, price movements of futures contracts may not correlate perfectly with price movements of the financial instruments underlying the futures contracts due to certain market distortions. A futures contract is an agreement between two parties to buy and sell a security, index or interest rate (each a “financial instrument”) for a set price on a future date. Certain futures contracts, such as futures contracts relating to individual securities, call for making or taking delivery of the underlying financial instrument. However, these contracts generally are closed out before delivery by entering into an offsetting purchase or sale of a matching futures contract (same exchange, underlying financial instrument, and delivery month). Other futures contracts, such as futures contracts on interest rates and indices, do not call for making or taking delivery of the underlying financial instrument, but rather are agreements pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the financial instrument at the close of the last trading day of the contract and the price at which the contract was originally written. These contracts also may be settled by entering into an offsetting futures contract.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract. Initially, the Fund will be required to deposit with the futures broker, known as a futures commission merchant (“FCM”), an amount of cash or securities equal to a varying specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, FCMs may establish margin deposit requirements that are higher than the exchange minimums. Cash held in the margin account generally is not income producing. However, couponbearing securities, such as Treasury securities, held in margin accounts generally will earn income. Subsequent payments to and from the FCM, called variation margin, will be made on a daily basis as the price of the underlying financial instrument fluctuates, making the futures contract more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the Fund as unrealized gains or losses. At any time prior to expiration of the futures contract, the Fund may elect to close the position by taking an opposite position that will operate to terminate its position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a gain or loss. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the Fund, the Fund may be entitled to the return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the Fund. Futures transactions also involve brokerage costs and the Fund may have to segregate additional liquid assets in accordance with applicable SEC requirements. See “—Segregation of Assets” below.

There are certain risks associated with the use of financial futures and options to hedge investment portfolios. There may be an imperfect correlation between price movements of the futures and options and price movements of the portfolio securities being hedged. Losses may be incurred in hedging transactions, which could reduce the portfolio gains that might have been realized if the hedging transactions had not been entered into. If the Fund engages in futures transactions or in the writing of options on futures, it will be required to maintain initial margin and maintenance margin and may be required to make daily variation margin payments in accordance with applicable rules of the exchanges and the Commodity Futures Trading Commission (“CFTC”). If the Fund purchases a financial futures contract or a call option or writes a put option in order to hedge the anticipated purchase of municipal securities, and if the Fund fails to complete the anticipated purchase transaction, the Fund may have a loss or a gain on the futures or options transaction that will not be offset by price movements in the municipal securities that were the subject of the anticipatory hedge. The cost of put options on debt securities or indexes effectively increases the cost of the securities subject to them, thereby reducing the yield otherwise available from these securities. If the Fund decides to use futures contracts or options on futures contracts for hedging purposes, the Fund will be required to establish an account for such purposes with one or more CFTC-registered futures commission merchants. A futures commission merchant could establish initial and maintenance margin requirements for the Fund that are greater than those which would otherwise apply to the Fund under applicable rules of the exchanges and the CFTC. There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a derivatives or futures or a futures option position, and the Fund would remain obligated to meet margin requirements until the position is closed. Futures exchanges may limit the amount of fluctuation permitted in certain futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of the current trading session. Once the daily limit has been reached in a futures contract subject to the limit, no more trades may be made on that day at a price beyond that limit. The daily limit governs only price movements during a particular trading day and therefore does not limit potential losses because the limit may work to prevent the liquidation of unfavorable positions. For example, futures prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of positions and subjecting some holders of futures contracts to substantial losses.

The requirements for qualification as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”) may also limit the extent to which the Fund may invest in futures, options on futures and swaps. See “Tax Matters.”

There is no assurance that these derivative strategies will be available at any time or that, if used, that the strategies will be successful.

For further information regarding these investment strategies and risks presented thereby, see Appendix B to this SAI.

ILLIQUID SECURITIES

The Fund may invest in illiquid securities (i.e., securities that are not readily marketable), including, but not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may be resold only pursuant to Rule 144A under the 1933 Act that are deemed to be illiquid, and certain repurchase agreements.

Restricted securities may be sold only in privately negotiated transactions or in a public offering with respect to which a registration statement is in effect under the 1933 Act. Where registration is required, the Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Fund might obtain a less favorable price than that which prevailed when it decided to sell. To the extent that the Board or its delegate determines that the price of any illiquid security provided by the pricing service is inappropriate, such security will be priced at a fair value as determined in good faith by the Board or its delegate.

INVERSE FLOATING RATE SECURITIES AND FLOATING RATE SECURITIES

Inverse floating rate securities (sometimes referred to as “inverse floaters”) are securities whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index. Generally, inverse floating rate securities represent beneficial interests in a special purpose trust formed by a third party sponsor for the purpose of holding municipal bonds. The special purpose trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds) and inverse floating rate securities (sometimes referred to as inverse floaters or residual interest securities). Both classes of beneficial interests are represented by certificates. The short-term floating rate securities have first priority on the cash flow from the municipal bonds held by the special purpose trust. Typically, a third party, such as a bank, broker-dealer or other financial institution, grants the floating rate security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees. The holder of the short-term floater effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, the institution granting the tender option will not be obligated to accept tendered short-term floaters in the event of certain defaults or a significant downgrade in the credit rating assigned to the bond issuer. For its inverse floating rate investment, the Fund receives the residual cash flow from the special purpose trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security, the Fund as the holder of the inverse floater assumes the interest rate cash flow risk and the market value risk associated with the municipal security deposited into the special purpose trust. The volatility of the interest cash flow and the residual market value will vary with the degree to which the trust is leveraged. This is expressed in the ratio of the total face value of the short-term floaters in relation to the value of the residual inverse floaters that are issued by the special purpose trust. The Fund expects to make limited investments in inverse floaters, with leverage ratios that may vary at inception between one and three times. In addition, all voting rights and decisions to be made with respect to any other rights relating to the municipal bonds held in the special purpose trust are passed through to the Fund, as the holder of the residual inverse floating rate securities. Because increases in the interest rate on the short-term floaters reduce the residual interest paid on inverse floaters, and because fluctuations in the value of the municipal bond deposited in the special purpose trust affect the value of the inverse floater only, and not the value of the short-term floater issued by the trust, inverse floaters’ value is generally more volatile than that of fixed rate bonds. The market price of inverse floating rate securities is generally more volatile than the underlying securities due to the leveraging effect of this ownership structure. These securities generally will underperform the market of fixed rate bonds in a rising interest rate environment (i.e., when bond values are falling), but tend to outperform the market of fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, inverse floaters typically offer the potential exceeding the yields available on fixed rate bonds with comparable credit quality, coupon, call provisions and maturity. Inverse floaters have varying degrees of liquidity based upon, among other things, the liquidity of the underlying securities deposited in a special purpose trust.

The Fund may invest in inverse floating rate securities, issued by special purpose trusts that have recourse to the Fund. In Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party sponsor of a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party sponsor of such inverse floater, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. Such agreements may expose the Fund to a risk of loss that exceeds its investment in the inverse floating rate securities. The Fund will segregate or earmark liquid assets with its custodian in accordance with the 1940 Act to cover its obligations with respect to its investments in special purpose trusts. Absent a shortfall and forbearance agreement, the Fund would not be required to make such a reimbursement. If the Fund chooses not to enter into such an agreement, the special purpose trust could be liquidated and the Fund could incur a loss. See also “Segregation of Assets” in this SAI.

The Fund may invest in both inverse floating rate securities and floating rate securities (as discussed below) issued by the same special purpose trust.

Investments in inverse floating rate securities have the economic effect of leverage. The use of leverage creates special risks for Common Shareholders. See the Prospectus under “Risk Factors—Inverse Floating Rate Securities Risk.”

Floating Rate Securities. The Fund may also invest in floating rate securities, as described above, issued by special purpose trusts. Floating rate securities may take the form of short-term floating rate securities or the option period may be substantially longer. Generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying bond deposited in the trust, the Fund as the holder of the floating rate security relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the trust provide for a liquidation of the municipal security deposited in the trust and the application of the proceeds to pay off the floating rate security. The trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate security.

OTHER INVESTMENT COMPANIES

The Fund may invest in securities of other open or closed-end investment companies (including ETFs) that invest primarily in municipal securities of the types in which the Fund may invest directly. In addition, the Fund may invest a portion of its Managed Assets in pooled investment vehicles (other than investment companies) that invest primarily in municipal securities of the types in which the Fund may invest directly. The Fund generally expects that it may invest in other investment companies and/or other pooled investment vehicles either during periods when it has large amounts of uninvested cash, such as the period shortly after the Fund receives the proceeds of an offering of its Common Shares, or borrowing or during periods when there is a shortage of attractive, high-yielding municipal securities available in the market. The Fund may invest in investment companies that are advised by NFALLC, Nuveen Asset Management or their respective affiliates to the extent permitted by applicable law and/or pursuant to exemptive relief from the SEC. The Fund has not received or applied for, nor does it currently intend to apply for, any such relief. As a stockholder in an investment company, the Fund will bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management, advisory and administrative fees with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other

investment companies. The Fund will consider its investment in underlying investment companies when determining its compliance with its policy to invest at least 80% of its Assets in municipal securities, the income from which is exempt from regular federal and California income tax.

NFALLC will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available municipal security investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. As described in the Prospectus, the NAV and market value of leveraged shares will be more volatile and the yield to Common Shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

Portfolio Turnover

The Fund may engage in portfolio trading when considered appropriate, but short-term trading will not be used as the primary means of achieving the Fund’s investment objectives. Although the Fund cannot accurately predict its annual portfolio turnover rate, it is generally not expected to exceed 25% under normal circumstances. For the fiscal year ended February 28, 2018, the Fund’s portfolio turnover rate was 14%. However, there are no limits on the Fund’s rate of portfolio turnover, and investments may be sold without regard to length of time held when, in Nuveen Asset Management’s opinion, investment considerations warrant such action. A higher portfolio turnover rate would result in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. Although these commissions and expenses are not reflected in the Fund’s “Total Annual Expenses” as disclosed in the Prospectus, they will be reflected in the Fund’s total return. In addition, high portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when distributed to shareholders, will be taxable as ordinary income. See “Tax Matters.”

REPURCHASE AGREEMENTS

As temporary investments, the Fund may invest in repurchase agreements. A repurchase agreement is a contractual agreement whereby the seller of securities (U.S. government securities or municipal securities) agrees to repurchase the same security at a specified price on a future date agreed upon by the parties. The agreed-upon repurchase price determines the yield during the Fund’s holding period. Repurchase agreements are considered to be loans collateralized by the underlying security that is the subject of the repurchase contract. Income generated from transactions in repurchase agreements will be taxable. See “Tax Matters” for information relating to the allocation of taxable income between Common Shares and Preferred Shares. The Fund will only enter into repurchase agreements with registered securities dealers or domestic banks that, in the opinion of NFALLC, present minimal credit risk. The risk to the Fund is limited to the ability of the issuer to pay the agreed-upon repurchase price on the delivery date; however, although the value of the underlying collateral at the time the transaction is entered into always equals or exceeds the agreed-upon repurchase price, if the value of the collateral declines there is a risk of loss of both principal and interest. In the event of default, the collateral may be sold but the Fund might incur a loss if the value of the collateral declines, and might incur disposition costs or experience delays in connection with liquidating the collateral. In addition, if bankruptcy proceedings are commenced with respect to the seller of the security, realization upon the collateral by the Fund may be delayed or limited. Nuveen Asset Management will monitor the value of the collateral at the time the transaction is entered into and at all times subsequent during the term of the repurchase agreement in an effort to determine that such value always equals or exceeds the agreed-upon repurchase price. In the event the value of the collateral declines below the repurchase price, Nuveen Asset Management will demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

SEGREGATION OF ASSETS

segregation”) liquid assets, or engage in other SEC or staff-approved measures, to “cover” open positions with respect to certain kinds of derivatives instruments. In the case of forward currency contracts that are not contractually required to cash settle, for example, the Fund must set aside liquid assets equal to such contracts’ full notional value while the positions are open. With respect to forward currency contracts that are contractually required to cash settle, however, the Fund is permitted to set aside liquid assets in an amount equal to the Fund’s daily marked-to-market net obligations (i.e., the Fund’s daily net liability) under the contracts, if any, rather than such contracts’ full notional value. The Fund reserves the right to modify its asset segregation policies in the future to comply with any changes in the positions from time to time articulated by the SEC or its staff regarding asset segregation.

To the extent that the Fund uses its assets to cover its obligations as required by the 1940 Act, the rules thereunder, and applicable positions of the SEC and its staff, such assets may not be used to cover other obligations. As a result of their segregation, such assets may not be used for other operational purposes. NFALLC and Nuveen Asset Management will monitor the Fund’s use of derivatives and will take action as necessary for the purpose of complying with the asset segregation policy stated above. Such actions may include the sale of the Fund’s portfolio investments.

SHORT-TERM INVESTMENTS

Short-Term Taxable Fixed Income Securities. For temporary defensive purposes or to keep cash on hand fully invested, the Fund may invest up to 100% of its net assets in cash equivalents and short-term taxable fixed-income securities, although the Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Short-term taxable fixed income investments are defined to include, without limitation, the following:

(1) U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities. U.S. government agency securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and the Government National Mortgage Association, whose securities are supported by the full faith and credit of the United States; (b) the Federal Home Loan Banks*, Federal Intermediate Credit Banks, and the Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) the Federal National Mortgage Association,* whose securities are supported by the discretionary authority of the U.S. government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. government provides financial support to such U.S. government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. government, its agencies, and instrumentalities do not guarantee the market value of their securities. Consequently, the value of such securities may fluctuate.

(2) Certificates of Deposit issued against funds deposited in a bank or a savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. The issuer of a certificate of deposit agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Under current Federal Deposit Insurance Company regulations, the maximum insurance payable as to any one certificate of deposit is $250,000; therefore, certificates of deposit purchased by the Fund may not be fully insured.

(3) Repurchase agreements, which involve purchases of debt securities. At the time the Fund purchases securities pursuant to a repurchase agreement, it simultaneously agrees to resell and redeliver such securities to the seller, who also simultaneously agrees to buy back the securities at a fixed price and time. This assures a predetermined yield for the Fund during its holding period, since the resale price is always greater

*	These securities are not backed by the full faith and credit of the United States Government.

than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Fund to invest temporarily available cash. The Fund may enter into repurchase agreements only with respect to obligations of the U.S. government, its agencies or instrumentalities; certificates of deposit; or bankers’ acceptances in which the Fund may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Fund is entitled to sell the underlying collateral. If the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Fund could incur a loss of both principal and interest. Nuveen Asset Management monitors the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. Nuveen Asset Management does so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(4) Commercial paper, which consists of short-term unsecured promissory notes, including variable rate master demand notes issued by corporations to finance their current operations. Master demand notes are direct lending arrangements between the Fund and a corporation. There is no secondary market for such notes. However, they are redeemable by the Fund at any time. Nuveen Asset Management will consider the financial condition of the corporation (e.g., earning power, cash flow, and other liquidity measures) and will continuously monitor the corporation’s ability to meet all of its financial obligations, because the Fund’s liquidity might be impaired if the corporation were unable to pay principal and interest on demand. Investments in commercial paper will be limited to commercial paper rated in the highest categories by a major rating agency and which mature within one year of the date of purchase or carry a variable or floating rate of interest.

Short-Term Tax-Exempt Municipal Securities. Short-term tax-exempt municipal securities are securities that are exempt from regular federal income tax and mature within three years or less from the date of issuance. Short-term tax-exempt municipal income securities are defined to include, without limitation, the following:

Bond Anticipation Notes (“BANs”) are usually general obligations of state and local governmental issuers which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds. The ability of an issuer to meet its obligations on its BANs is primarily dependent on the issuer’s access to the long-term municipal bond market and the likelihood that the proceeds of such bond sales will be used to pay the principal and interest on the BANs.

Tax Anticipation Notes (“TANs”) are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues. TANs are usually general obligations of the issuer. A weakness in an issuer’s capacity to raise taxes due to, among other things, a decline in its tax base or a rise in delinquencies, could adversely affect the issuer’s ability to meet its obligations on outstanding TANs.

Revenue Anticipation Notes (“RANs”) are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the notes. In general, they also constitute general obligations of the issuer. A decline in the receipt of projected revenues, such as anticipated revenues from another level of government, could adversely affect an issuer’s ability to meet its obligations on outstanding RANs. In addition, the possibility that the revenues would, when received, be used to meet other obligations could affect the ability of the issuer to pay the principal and interest on RANs.

Construction Loan Notes are issued to provide construction financing for specific projects. Frequently, these notes are redeemed with funds obtained from the Federal Housing Administration.

Bank Notes are notes issued by local government bodies and agencies, such as those described above to commercial banks as evidence of borrowings. The purposes for which the notes are issued are varied but they are frequently issued to meet short-term working capital or capital-project needs. These notes may have risks similar to the risks associated with TANs and RANs.

Tax-Exempt Commercial Paper (“Municipal Paper”) represents very short-term unsecured, negotiable promissory notes issued by states, municipalities and their agencies. Payment of principal and interest on issues of municipal paper may be made from various sources, to the extent the funds are available therefrom. Maturities of municipal paper generally will be shorter than the maturities of TANs, BANs or RANs. There is a limited secondary market for issues of Municipal Paper.

Certain municipal securities may carry variable or floating rates of interest whereby the rate of interest is not fixed but varies with changes in specified market rates or indices, such as a bank prime rate or a tax-exempt money market index.

While the various types of notes described above as a group represent the major portion of the short-term tax-exempt note market, other types of notes are available in the marketplace and the Fund may invest in such other types of notes to the extent permitted under its investment objectives, policies and limitations. Such notes may be issued for different purposes and may be secured differently from those mentioned above.

AUCTION RATE SECURITIES

Municipal securities also include auction rate municipal securities and auction rate preferred securities issued by closed-end investment companies that invest primarily in municipal securities (collectively, “auction rate securities”). In recent market environments, auctions have failed, which adversely affects the liquidity and price of auction rate securities, and are unlikely to resume. Provided that the auction mechanism is successful, auction rate securities usually permit the holder to sell the securities in an auction at par value at specified intervals. The dividend is reset by “Dutch” auction in which bids are made by broker-dealers and other institutions for a certain amount of securities at a specified minimum yield. The dividend rate set by the auction is the lowest interest or dividend rate that covers all securities offered for sale. While this process is designed to permit auction rate securities to be traded at par value, there is a risk that an auction will fail due to insufficient demand for the securities. Moreover, between auctions, there may be no secondary market for these securities, and sales conducted on a secondary market may not be on terms favorable to the seller. Auction rate securities may be called by the issuer. Thus, with respect to liquidity and price stability, auction rate securities may differ substantially from cash equivalents, notwithstanding the frequency of auctions and the credit quality of the security. The Fund’s investments in auction rate securities of closed-end funds are subject to the limitations prescribed by the 1940 Act. The Fund will indirectly bear its proportionate share of any management and other fees paid by such closed-end funds in addition to the advisory fees payable directly by the Fund.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may buy and sell municipal securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date. On such transactions the payment obligation and the interest rate are fixed at the time the purchaser enters into the commitment. Beginning on the date the Fund enters into a commitment to purchase securities on a when-issued or delayed delivery basis, the Fund is required under the rules of the SEC to maintain in a separate account liquid assets, consisting of cash, cash equivalents or liquid securities having a market value, at all times, of at least equal to the amount of any delayed payment commitment. Income generated by any such assets which provide taxable income for federal income tax purposes is includable in the taxable income of the Fund. The Fund may enter into contracts to purchase municipal securities on a forward basis (i.e., where settlement will occur more than 60 days from the date of the transaction) only to the extent that the Fund specifically collateralizes such obligations with a security that is expected to be called or mature within sixty days before or after the settlement date of the forward

transaction. The commitment to purchase securities on a when-issued, delayed delivery or forward basis may involve an element of risk because no interest accrues on the bonds prior to settlement and at the time of delivery the market value may be less than cost.

STRUCTURED NOTES

The Fund may utilize structured notes and similar instruments for investment purposes and also for hedging purposes. Structured notes are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but not ordinarily below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending upon a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index or indices or other assets. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss. These types of investments may generate taxable income.

ZERO COUPON BONDS

A zero coupon bond is a bond that typically does not pay interest either for the entire life of the obligation or for an initial period after the issuance of the obligation. When held to its maturity, the holder receives the par value of the zero coupon bond, which generates a return equal to the difference between the purchase price and its maturity value. A zero coupon bond is normally issued and traded at a deep discount from face value. This original issue discount (“OID”) approximates the total amount of interest the security will accrue and compound prior to its maturity and reflects the payment deferral and credit risk associated with the instrument. Because zero coupon securities and other OID instruments do not pay cash interest at regular intervals, the instruments’ ongoing accruals require ongoing judgments concerning the collectability of deferred payments and the value of any associated collateral. As a result, these securities may be subject to greater value fluctuations and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash on a current basis. Because zero coupon bonds, and OID instruments generally, allow an issuer to avoid or delay the need to generate cash to meet current interest payments, they may involve greater payment deferral and credit risk than coupon loans and bonds that pay interest currently or in cash. The Fund generally will be required to distribute dividends to shareholders representing the income of these instruments as it accrues, even though the Fund will not receive all of the income on a current basis or in cash. Thus, the Fund may have to sell other investments, including when it may not be advisable to do so, and use the cash proceeds to make income distributions to its shareholders. For accounting purposes, these cash distributions to shareholders will not be treated as a return of capital.

MANAGEMENT OF THE FUND

TRUSTEES AND OFFICERS

The management of the Fund, including general supervision of the duties performed for the Fund under the Investment Management Agreement (as defined under “Investment Adviser, Sub-Adviser and Portfolio Manager—Investment Management Agreement and Related Fees”), is the responsibility of the Board. The number of trustees of the Fund is eleven, one of whom is an “interested person” (as the term “interested person” is defined in the 1940 Act) and ten of whom are not interested persons (referred to herein as “independent trustees”). None of the independent trustees has ever been a director, trustee or employee of, or consultant to, Nuveen Investments, NFALLC, Nuveen Asset Management, or their affiliates. The Board is divided into three classes, Class I, Class II and Class III, the Class I trustees serving until the 2019 annual meeting, the Class II trustees serving until the 2020 annual meeting and the Class III trustees serving until the 2018 annual meeting, in each case until their respective successors are elected and qualified, as described below. Currently, William C. Hunter, Judith M. Stockdale, Carole E. Stone and Margaret L. Wolff are slated in Class I, John K. Nelson, Terence J. Toth and Robert L. Young are slated in Class II, and Margo L. Cook, Jack B. Evans, Albin F. Moschner and William J. Schneider are slated in Class III. If the Fund has preferred shares outstanding, two of the Fund’s trustees will be elected by the holders of such preferred shares, voting separately as a class. The remaining trustees of the Fund are elected by holders of Common Shares and Preferred Shares, voting separately as a class. In the event that the Fund fails to pay dividends on outstanding preferred shares for two years, holders of preferred shares are entitled to elect a majority of trustees of the Fund. The officers of the Fund serve annual terms through August of each year and are elected on an annual basis. The names, business addresses and years of birth of the trustees and officers of the Fund, their principal occupations and other affiliations during the past five years, the number of portfolios each oversees and other directorships they hold are set forth below. Except as noted in the table below, the trustees of the Fund are directors or trustees, as the case may be, of 175 Nuveen-sponsored registered investment companies (the “Nuveen Funds”), which includes 89 open-end mutual funds (the “Nuveen Mutual Funds”), 75 closed-end funds and 11 NuShares ETFs.

Board Leadership Structure and Risk Oversight

The Board of Directors or the Board of Trustees (as the case may be, each is referred to hereafter as the “Board” and the trustees or directors of the Nuveen Funds, as applicable, are referred to herein as “Trustees”) oversees the operations and management of the Nuveen Fund (the “Nuveen Funds”), including the duties performed for the Nuveen Funds by NFALLC and each Nuveen Fund’s sub-adviser, as applicable. The Board has adopted a unitary board structure. A unitary board consists of one group of trustees who serve on the board of every Nuveen Fund in the fund complex. In adopting a unitary board structure, the Trustees seek to provide effective governance through establishing a board, the overall composition of which, will, as a body, possess the appropriate skills, independence and experience to oversee the Nuveen Funds’ business. With this overall framework in mind, when the Board, through its Nominating and Governance Committee discussed below, seeks

nominees for the Board, the Trustees consider, not only the candidate’s particular background, skills and experience, among other things, but also whether such background, skills and experience enhance the Board’s diversity and at the same time complement the Board given its current composition and the mix of skills and experiences of the incumbent Trustees.

The Board believes the unitary board structure enhances good and effective governance, particularly given the nature of the structure of the investment company complex. Funds in the same complex generally are served by the same service providers and personnel and are governed by the same regulatory scheme which raises common issues that must be addressed by the trustees across the fund complex (such as compliance, valuation, liquidity, brokerage, trade allocation or risk management). The Board believes it is more efficient to have a single board review and oversee common policies and procedures which increases the Board’s knowledge and expertise with respect to the many aspects of fund operations that are complex-wide in nature. The unitary structure also enhances the Board’s influence and oversight over NFALLC and other service providers.

In an effort to enhance the independence of the Board, the Board also has a Chairman that is an independent trustee. The Board recognizes that a chairman can perform an important role in setting the agenda for the Board, establishing the boardroom culture, establishing a point person on behalf of the Board for fund management, and reinforcing the Board’s focus on the long-term interests of shareholders. The Board recognizes that a chairman may be able to better perform these functions without any conflicts of interests arising from a position with fund management. William J. Schneider currently serves as the Independent Chairman of the Board. Effective July 1, 2018, Terence J. Toth will replace Mr. Schneider as the Independent Chairman of the Board. Specific responsibilities of the Chairman include: (i) presiding at all meetings of the Board and of the shareholders; (ii) seeing that all orders and resolutions of the Trustees are carried into effect; and (iii) maintaining records of and, whenever necessary, certifying all proceedings of the Trustees and the shareholders.

Although the Board has direct responsibility over various matters (such as advisory contracts, underwriting contracts and Fund performance), the Board also exercises certain of its oversight responsibilities through several committees that it has established and which report back to the full Board. The Board believes that a committee structure is an effective means to permit Trustees to focus on particular operations or issues affecting the Nuveen Funds, including risk oversight. More specifically, with respect to risk oversight, the Board has delegated matters relating to valuation and compliance to certain committees (as summarized below) as well as certain aspects of investment risk. In addition, the Board believes that the periodic rotation of Trustees among the different committees allows the Trustees to gain additional and different perspectives of the Fund’s operations. The Board has established six standing committees: the Executive Committee, the Dividend Committee, the Closed-End Funds Committee, the Audit Committee, the Compliance, Risk Management and Regulatory Oversight Committee, and the Nominating and Governance Committee. The Board also may from time to time create ad hoc committees to focus on particular issues as the need arises. The membership and functions of the standing committees are summarized below.

The Executive Committee, which meets between regular meetings of the Board, is authorized to exercise all of the powers of the Board. The members of the Executive Committee are William J. Schneider (Chair), Margo L. Cook and Terence J. Toth. During the fiscal year ended February 28, 2018, the Executive Committee met one (1) time.

The Dividend Committee is authorized to declare distributions on each Nuveen Fund’s shares including, but not limited to, regular and special dividends, capital gains and ordinary income distributions. The members of the Dividend Committee are William C. Hunter (Chair), Albin F. Moschner, Margaret L. Wolff and Terence J. Toth. During the fiscal year ended February 28, 2018, the Dividend Committee met four (4) times.

The Compliance, Risk Management and Regulatory Oversight Committee (the “Compliance Committee”) is responsible for the oversight of compliance issues, risk management and other regulatory matters affecting the Nuveen Funds that are not otherwise the jurisdiction of the other committees. The Board has adopted and

periodically reviews policies and procedures designed to address the Nuveen Funds’ compliance and risk matters. As part of its duties, the Compliance Committee reviews the policies and procedures relating to compliance matters and recommends modifications thereto as necessary or appropriate to the full Board; develops new policies and procedures as new regulatory matters affecting the Nuveen Funds arise from time to time; evaluates or considers any comments or reports from examinations from regulatory authorities and responses thereto; and performs any special reviews, investigations or other oversight responsibilities relating to risk management, compliance and/or regulatory matters as requested by the Board.

In addition, the Compliance Committee is responsible for risk oversight, including, but not limited to, the oversight of risks related to investments and operations. Such risks include, among other things, exposures to particular issuers, market sectors, or types of securities; risks related to product structure elements, such as leverage; and techniques that may be used to address those risks, such as hedging and swaps. In assessing issues brought to the committee’s attention or in reviewing a particular policy, procedure, investment technique or strategy, the Compliance Committee evaluates the risks to the Nuveen Funds in adopting a particular approach or resolution compared to the anticipated benefits to the Nuveen Funds and their shareholders. In fulfilling its obligations, the Compliance Committee meets on a quarterly basis, and at least once a year in person. The Compliance Committee receives written and oral reports from the Nuveen Funds’ Chief Compliance Officer (“CCO”) and meets privately with the CCO at each of its quarterly meetings. The CCO also provides an annual report to the full Board regarding the operations of the Nuveen Funds’ and other service providers’ compliance programs as well as any recommendations for modifications thereto. The Compliance Committee also receives reports from the investment services group of Nuveen Investments regarding various investment risks. Notwithstanding the foregoing, the full Board also participates in discussions with management regarding certain matters relating to investment risk, such as the use of leverage and hedging. The investment services group therefore also reports to the full Board at its quarterly meetings regarding, among other things, Fund performance and the various drivers of such performance. Accordingly, the Board directly and/or in conjunction with the Compliance Committee oversees matters relating to investment risks. Matters not addressed at the committee level are addressed directly by the full Board. The committee operates under a written charter adopted and approved by the Board. The members of the Compliance Committee are Albin F. Moschner, John K. Nelson (Chair), Judith M. Stockdale, Margaret L. Wolff and Robert L. Young. During the fiscal year ended February 28, 2018, the Compliance Committee met nine (9) times.

The Audit Committee assists the Board in the oversight and monitoring of the accounting and reporting policies, processes and practices of the Nuveen Funds, and the audits of the financial statements of the Nuveen Funds; the quality and integrity of the financial statements of the Nuveen Funds; the Nuveen Funds’ compliance with legal and regulatory requirements relating to the Nuveen Funds’ financial statements; the independent auditors’ qualifications, performance and independence; and the pricing procedures of the Nuveen Funds and the internal valuation group of Nuveen. It is the responsibility of the Audit Committee to select, evaluate and replace any independent auditors (subject only to Board and, if applicable, shareholder ratification) and to determine their compensation. The Audit Committee is also responsible for, among other things, overseeing the valuation of securities comprising the Nuveen Funds’ portfolios. Subject to the Board’s general supervision of such actions, the Audit Committee addresses any valuation issues, oversees the Nuveen Funds’ pricing procedures and actions taken by Nuveen’s internal valuation group which provides regular reports to the committee, reviews any issues relating to the valuation of the Nuveen Funds’ securities brought to its attention and considers the risks to the Nuveen Funds in assessing the possible resolutions to these matters. The Audit Committee also may consider any financial risk exposures for the Nuveen Funds in conjunction with performing its functions.

To fulfill its oversight duties, the Audit Committee receives annual and semi-annual reports and has regular meetings with the external auditors for the Nuveen Funds and NFALLC’s internal audit group at Nuveen Investments. The Audit Committee also may review in a general manner the processes the Board or other Board committees have in place with respect to risk assessment and risk management as well as compliance with legal and regulatory matters relating to the Nuveen Funds’ financial statements. The committee operates under a written charter adopted and approved by the Board. Members of the Audit Committee shall be independent (as

set forth in the charter) and free of any relationship that, in the opinion of the trustees, would interfere with their exercise of independent judgment as an Audit Committee member. The members of the Audit Committee are Jack B. Evans (Chair), William C. Hunter, John K. Nelson, Carole E. Stone and Terence J. Toth, each of whom is an Independent Trustee of the Nuveen Funds. During the fiscal year ended February 28, 2018, the Audit Committee met four (4) times.

The Nominating and Governance Committee is responsible for seeking, identifying and recommending to the Board qualified candidates for election or appointment to the Board. In addition, the Nominating and Governance Committee oversees matters of corporate governance, including the evaluation of Board performance and processes, the assignment and rotation of committee members, and the establishment of corporate governance guidelines and procedures, to the extent necessary or desirable, and matters related thereto. Although the unitary and committee structure has been developed over the years and the Nominating and Governance Committee believes the structure has provided efficient and effective governance, the committee recognizes that as demands on the Board evolve over time (such as through an increase in the number of funds overseen or an increase in the complexity of the issues raised), the committee must continue to evaluate the Board and committee structures and their processes and modify the foregoing as may be necessary or appropriate to continue to provide effective governance. Accordingly, the Nominating and Governance Committee has a separate meeting each year to, among other things, review the Board and committee structures, their performance and functions, and recommend any modifications thereto or alternative structures or processes that would enhance the Board’s governance over the Nuveen Funds’ business.

In addition, the Nominating and Governance Committee, among other things, makes recommendations concerning the continuing education of trustees; monitors performance of legal counsel and other service providers; establishes and monitors a process by which security holders are able to communicate in writing with members of the Board; and periodically reviews and makes recommendations about any appropriate changes to Trustee compensation. In the event of a vacancy on the Board, the Nominating and Governance Committee receives suggestions from various sources, including suggestions from fund security holders, as to suitable candidates. Suggestions should be sent in writing to Lorna Ferguson, Manager of Fund Board Relations, Nuveen LLC, 333 West Wacker Drive, Chicago, IL 60606. The Nominating and Governance Committee sets appropriate standards and requirements for nominations for new Trustees and reserves the right to interview any and all candidates and to make the final selection of any new Trustees. In considering a candidate’s qualifications, each candidate must meet certain basic requirements, including relevant skills and experience, time availability (including the time requirements for due diligence site visits to internal and external sub-advisers and service providers) and, if qualifying as an Independent Trustee candidate, independence from NFALLC, subadvisors, underwriters or other service providers, including any affiliates of these entities. These skill and experience requirements may vary depending on the current composition of the Board, since the goal is to ensure an appropriate range of skills, diversity and experience, in the aggregate. Accordingly, the particular factors considered and weight given to these factors will depend on the composition of the Board and the skills and backgrounds of the incumbent Trustees at the time of consideration of the nominees. All candidates, however, must meet high expectations of personal integrity, independence, governance experience and professional competence. All candidates must be willing to be critical within the Board and with management and yet maintain a collegial and collaborative manner toward other Board members. The committee operates under a written charter adopted and approved by the Board. This committee is composed of the Independent Trustees of the Nuveen Funds. The members of the Nominating and Governance Committee are William J. Schneider (Chair), Jack B. Evans, William C. Hunter, Albin F. Moschner, John K. Nelson, Judith M. Stockdale, Carole E. Stone, Terence J. Toth, Margaret L. Wolff and Robert L. Young. During the fiscal year ended February 28, 2018, the Nominating and Governance Committee met five (5) times.

The Closed-End Funds Committee is responsible for assisting the Board in the oversight and monitoring of the Nuveen Funds that are registered as closed-end management investment companies (the “Closed-End Funds”). The committee may review and evaluate matters related to the formation and the initial presentation to the Board of new Closed-End Funds and may review and evaluate any matters relating to existing Closed-End Funds. The committee operates under a written charter adopted and approved by the Board. The members of the

Closed-End Funds Committee are Carole E. Stone (Chair), Margo L. Cook, Jack B. Evans, Albin F. Moschner, William J. Schneider, Terence J. Toth and Robert L. Young. During the fiscal year ended February 28, 2018, the Closed-End Funds Committee met four (4) times.

Board Diversification and Trustee Qualifications

In determining that a particular Trustee was qualified to serve on the Board, the Board has considered each Trustee’s background, skills, experience and other attributes in light of the composition of the Board with no particular factor controlling. The Board believes that Trustees need to have the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with Fund management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties, and the Board believes each trustee satisfies this standard. An effective trustee may achieve this ability through his or her educational background; business, professional training or practice; public service or academic positions; experience from service as a board member or executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and/or other life experiences. Accordingly, set forth below is a summary of the experiences, qualifications, attributes, and skills that led to the conclusion, as of the date of this document, that each Trustee should continue to serve in that capacity. References to the experiences, qualifications, attributes and skills of Trustees are pursuant to requirements of the SEC, do not constitute holding out of the Board or any Trustee as having any special expertise or experience and shall not impose any greater responsibility or liability on any such person or on the Board by reason thereof.

COMPENSATION

The following table shows, for each independent trustee, (1) the aggregate compensation paid to each Trustee by the Fund for its fiscal year ended February 28, 2018, (2) the amount of total compensation paid to each Trustee by the Fund that has been deferred and (3) the total compensation paid to each Trustee by the Nuveen Funds during the calendar year ended December 31, 2017. The Fund does not have a retirement or pension plan. The officers and Trustees affiliated with Nuveen Investments serve without any compensation from the Fund. Certain of the Nuveen Funds have a deferred compensation plan (the “Compensation Plan”) that permits any trustee who is not an “interested person” of certain funds to elect to defer receipt of all or a portion of his or her compensation as a trustee. The deferred compensation of a participating trustee is credited to the book reserve account of a fund when the compensation would otherwise have been paid to the trustee. The value of the trustee’s deferral account at any time is equal to the value that the account would have had if contributions to the account had been invested and reinvested in shares of one or more of the eligible Nuveen Funds. At the time for commencing distributions from a trustee’s deferral account, the trustee may elect to receive distributions in a lump sum or over a period of five years. The Fund will not be liable for any other fund’s obligations to make distributions under the Compensation Plan.

(1)	The compensation paid, including deferred amounts, to the independent trustees for the fiscal year ended February 28, 2018 for services to the Fund.

(2)

Pursuant to a deferred compensation agreement with certain of the Nuveen Funds, deferred amounts are treated as though an equivalent dollar amount has been invested in shares of one or more eligible Nuveen Funds. Total deferred fees for the Fund (including the return from the assumed investment in the eligible Nuveen Funds) payable are stated above.

(3)

Based on the compensation paid (including any amounts deferred) for the calendar year ended December 31, 2017 for services to the Nuveen open-end and closed-end funds. Because the Nuveen Funds in the Fund Complex have different fiscal year ends, the amounts shown in this column are presented on a calendar year basis.

(4)	Mr. Young was appointed to the Board effective July 1, 2017.

Effective January 1, 2018, Independent Trustees receive a $185,000 annual retainer, increased from $177,500 as of January 1, 2017, increased from $170,000 as of January 1, 2016, plus (a) a fee of $6,000 per day, which was increased from $5,750 per day as of January 1, 2017, for attendance in-person or by telephone at regularly scheduled meetings of the Board; (b) a fee of $3,000 per meeting for attendance in-person or by telephone at special, non-regularly scheduled Board Meetings where in-person attendance is required and $2,000 per meeting for

attendance by telephone or in-person at such meetings where in-person attendance is not required; (c) a fee of $2,500 per meeting for attendance in-person or by telephone at Audit Committee meetings where in-person attendance is required and $2,000 per meeting for attendance by telephone or in-person at such meetings where in-person attendance is not required; (d) a fee of $2,500 per meeting for attendance in-person or by telephone at Compliance, Risk Management and Regulatory Oversight Committee meetings where in-person attendance is required and $2,000 per meeting for attendance by telephone or in-person at such meetings where in-person attendance is not required; (e) a fee of $1,000 per meeting for attendance in-person or by telephone at Dividend Committee meetings; (f) a fee of $500 per meeting for attendance in-person or by telephone at all other committee meetings ($1,000 for shareholder meetings) where in-person attendance is required and $250 per meeting for attendance by telephone or in-person at such committee meetings (excluding shareholder meetings) where in-person attendance is not required and $100 per meeting when the Executive Committee acts as pricing committee for IPOs, plus, in each case, expenses incurred in attending such meetings, provided that no fees are received for meetings held on days on which regularly scheduled Board meetings are held and (g) a fee of $2,500 per meeting for attendance in-person or by telephone at Closed-End Funds Committee meetings where in-person attendance is required and $2,000 per meeting for attendance by telephone or in-person at such meetings where in-person attendance is not required; provided that no fees are received for meetings held on days on which regularly scheduled Board meetings are held. In addition to the payments described above, the Chairman of the Board receives $90,000, increased from $80,000 as of January 1, 2017, and the chairpersons of the Audit Committee, the Dividend Committee, the Compliance, Risk Management and Regulatory Oversight Committee, the Nominating and Governance Committee and the Closed-End Funds Committee receive $12,500 each as additional retainers. Independent trustees also receive a fee of $3,000 per day for site visits to entities that provide services to the Nuveen Funds on days on which no Board Meeting is held. When ad hoc committees are organized, the Nominating and Governance Committee will at the time of formation determine compensation to be paid to the members of such committee; however, in general, such fees will be $1,000 per meeting for attendance in-person or by telephone at ad hoc committee meetings where in-person attendance is required and $500 per meeting for attendance by telephone or in-person at such meetings where in-person attendance is not required. The annual retainer, fees and expenses are allocated among the Nuveen Funds on the basis of relative net assets, although management may, in its discretion, establish a minimum amount to be allocated to each fund. In certain instances fees and expenses will be allocated only to those Nuveen Funds that are discussed at a given meeting.

The Fund has no employees. The officers of the Fund and the trustees of the Fund who are not independent trustees serve without any compensation from the Fund.

INVESTMENT ADVISER AND SUB-ADVISER

Investment Adviser. Nuveen Fund Advisors, LLC, the Fund’s investment adviser, is responsible for overseeing the Fund’s overall investment strategy and implementation. NFALLC offers advisory and investment management services to a broad range of investment company clients. NFALLC has overall responsibility for management of the Fund, oversees the management of the Fund’s portfolio, manages the Fund’s business affairs and provides certain clerical, bookkeeping and other administrative services. NFALLC is located at 333 West Wacker Drive, Chicago, Illinois 60606. NFALLC is a subsidiary of Nuveen, LLC (“Nuveen”), the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). TIAA is a life insurance company founded in 1918 by the Carnegie Foundation for the Advancement of Teaching and is the companion organization of College Retirement Equities Fund. As of March 31, 2018, Nuveen managed approximately $967 billion in assets, of which approximately $139 billion was managed by NFALLC.

Investment Management Agreement and Related Fees. Pursuant to an investment management agreement between NFALLC and the Fund (the “Investment Management Agreement”), the Fund has agreed to pay an annual management fee for the overall advisory and administrative services and general office facilities provided by NFALLC. The Fund’s management fee is separated into two components—a complex-level component, based on the aggregate amount of all fund assets managed by NFALLC, and a specific fund-level

component, based only on the amount of assets within the Fund. This pricing structure enables Nuveen fund shareholders to benefit from growth in the assets within each individual fund as well as from growth in the amount of complex-wide assets managed by NFALLC.

Fund-Level Fee. The annual fund-level fee for the Fund, payable monthly, is calculated according to the following schedule:


Average Daily Managed Assets*	Fund-Level Fee Rate
For the first $125 million		0.4500	%
For the next $125 million		0.4375	%
For the next $250 million		0.4250	%
For the next $500 million		0.4125	%
For the next $1 billion		0.4000	%
For the next $3 billion		0.3750	%
For Managed Assets over $5 billion		0.3625	%

Complex-Level Fee. The annual complex-level fee for the Fund, payable monthly, is calculated by multiplying the current complex-wide fee rate, determined according to the following schedule, by the Fund’s daily managed assets.


Complex-Level Eligible Asset Breakpoint Level*	Effective Complex-Level Fee Rate at Breakpoint Level
$55 billion		0.2000	%
$56 billion		0.1996	%
$57 billion		0.1989	%
$60 billion		0.1961	%
$63 billion		0.1931	%
$66 billion		0.1900	%
$71 billion		0.1851	%
$76 billion		0.1806	%
$80 billion		0.1773	%
$91 billion		0.1691	%
$125 billion		0.1599	%
$200 billion		0.1505	%
$250 billion		0.1469	%
$300 billion		0.1445	%

For the complex-level fees, managed assets include closed-end fund assets managed by NFALLC that are attributable to certain types of leverage. For these purposes, leverage includes the funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by NFALLC as to certain funds to limit the amount of such assets for determining managed assets in certain circumstances. The complex-level fee is calculated based upon the aggregate daily managed assets of all Nuveen open-end and closed-end funds that constitute “eligible assets.” Eligible assets do not include assets attributable to investments in other Nuveen Funds or assets in excess of a determined amount (originally $2 billion) added to the Nuveen Funds fund complex in connection with NFALLC’s assumption of the management of the former First American Funds effective January 1, 2011. As of February 28, 2018, the complex-level fee rate for the Fund was 0.1595%.

The following table sets forth the management fee paid by the Fund for the last three fiscal years:


	Management Fee Net of Expense Reimbursement for the Fiscal Year Ended		Expense Reimbursement for the Fiscal Year Ended
Fiscal year ended February 29, 2016	$	6,606,749	$	—
Fiscal year ended February 28, 2017	$	7,026,493	$	—
Fiscal year ended February 28, 2018	$	7,078,953	$	—

In addition to the fee of NFALLC, the Fund pays all other costs and expenses of its operations, including compensation of its directors (other than those affiliated with NFALLC and Nuveen Asset Management), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses of issuing Preferred Shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies and taxes, if any. All fees and expenses are accrued daily and deducted before payment of dividends to investors.

A discussion regarding the Board’s most recent approval of the Investment Management Agreement may be found in the Fund’s semi-annual report to shareholders for the period ended August 31 of each year.

Investment Sub-Adviser. Pursuant to a sub-advisory agreement between NFALLC and Nuveen Asset Management (the “Sub-Advisory Agreement”), Nuveen Asset Management, LLC, 333 West Wacker Drive, Chicago, Illinois 60606, serves as the Fund’s sub-adviser. Nuveen Asset Management is a registered investment adviser and is a wholly-owned subsidiary of NFALLC. Nuveen Asset Management oversees day-to-day operations and provides portfolio management services to the Fund. Pursuant to the Sub-Advisory Agreement, Nuveen Asset Management is compensated for the services it provides to the Fund with a portion of the management fee NFALLC receives from the Fund. NFALLC and Nuveen Asset Management retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

Sub-Advisory Agreement and Related Fees. Pursuant to the Sub-Advisory Agreement, Nuveen Asset Management will receive from NFALLC a management fee equal to 38.4620% of NFALLC’s net management fee from the Fund. NFALLC and Nuveen Asset Management retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

The following table sets forth the management fee paid by NFALLC to Nuveen Asset Management for the last three fiscal years:


	Sub-Advisory Fees Paid by NFALLC to Nuveen Asset Management
Fiscal year ended February 29, 2016	$	2,541,055
Fiscal year ended February 28, 2017	$	2,702,495
Fiscal year ended February 28, 2018	$	2,722,671

A discussion regarding the Board’s decision to renew the Investment Management Agreement and the Sub-Advisory Agreements may be found in the Fund’s semi-annual report to shareholders for the period ended August 31 of each year.

PORTFOLIO MANAGER

Unless otherwise indicated, the information below is provided as of the date of this SAI.

Portfolio Management. Scott R. Romans, PhD (the “Portfolio Manager”), Senior Vice President of Nuveen Asset Management, joined Nuveen in 2000 as a senior analyst in the education sector. In 2003, he was assigned

management responsibility for several closed- and open-ended municipal bond funds most of which are state funds covering California and other western states. Currently, he manages investments for 14 Nuveen-sponsored investment companies. He holds an undergraduate degree from the University of Pennsylvania and an MA and PhD from the University of Chicago.

The Portfolio Manager also has responsibility for the day-to-day management of accounts other than the Fund. Information regarding these other accounts is set forth below.


	Number of Other Accounts Managed and Assets by Account Type as of February 28, 2018
Portfolio Manager	Type of Account Managed	Number of Accounts		Total Assets		Number of Accounts with Performance Based Fees		Assets of Account with Performance Based Fees
Scott R. Romans	Registered Investment Companies		13	$	12.81 billion		0	$	0
	Other Pooled Investment Vehicles		0		0		0	$	0
	Other Accounts		3		4.4 million		0	$	0

As shown in the above table, the Portfolio Manager may manage accounts in addition to the Fund. The potential for conflicts of interest exists when a portfolio manager manages other accounts with similar investment objectives and strategies to the Fund (“Similar Accounts”). Potential conflicts may include, for example, conflicts between investment strategies and conflicts in the allocation of investment opportunities.

Responsibility for managing NFALLC’s clients’ portfolios is organized according to investment strategies. Generally, client portfolios with similar strategies are managed using the same objectives, approach and philosophy. Therefore, portfolio holdings, relative position sizes and sector exposures tend to be similar across similar portfolios which minimizes the potential for conflicts of interest.

NFALLC may receive more compensation with respect to certain Similar Accounts than that received with respect to the Fund or may receive compensation based in part on the performance of certain Similar Accounts. This may create a potential conflict of interest for the Fund’s portfolio manager by providing an incentive to favor these Similar Accounts when, for example, placing securities transactions. Potential conflicts of interest may arise with both the aggregation and allocation of securities transactions and allocation of limited investment opportunities. Allocations of aggregated trades, particularly trade orders that were only partially completed due to limited availability, and allocation of investment opportunities generally, could raise a potential conflict of interest.

Nuveen Asset Management has policies and procedures designed to manage these conflicts described above such as allocation of investment opportunities to achieve fair and equitable allocation of investment opportunities among its clients over time. For example, orders for the same equity security are aggregated on a continual basis throughout each trading day consistent with Nuveen Asset Management’s duty of best execution for its clients. If aggregated trades are fully executed, accounts participating in the trade will be allocated their pro rata share on an average price basis. Partially completed orders will be allocated among the participating accounts on a pro-rata average price basis as well.

Compensation. The Portfolio Manager’s compensation consists primarily of base pay, an annual cash bonus and long-term incentive payments.

Base pay. Base pay is determined based upon an analysis of the portfolio manager’s general performance, experience, and market levels of base pay for such position.

Annual cash bonus. The Portfolio Manager is eligible for an annual cash bonus based on investment performance, qualitative evaluation and financial performance of Nuveen Asset Management.

A portion of the Portfolio Manager’s annual cash bonus is based on the Fund’s pre-tax investment performance, generally measured over the past one- and three or five-year periods unless the Portfolio Manager’s tenure is shorter. Investment performance for the Fund generally is determined by evaluating the Fund’s performance relative to its benchmark(s) and/or Lipper industry peer group.

A portion of the cash bonus is based on a qualitative evaluation made by the Portfolio Manager’s supervisor taking into consideration a number of factors, including the portfolio manager’s team collaboration, expense management, support of personnel responsible for asset growth, and his or her compliance with Nuveen Asset Management’s policies and procedures.

The final factor influencing the Portfolio Manager’s cash bonus is the financial performance of Nuveen Asset Management based on its operating earnings.

Long-term incentive compensation. Certain key employees of Nuveen Asset Management, including certain portfolio managers, have received profits interests in Nuveen Asset Management which entitle their holders to participate in the firm’s growth over time.

Material Conflicts of Interest. Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented a number of potential conflicts, including, among others, those discussed below.

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. Nuveen Asset Management seeks to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most accounts managed by a portfolio manager in a particular investment strategy are managed using the same investment models.

If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one account, an account may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible accounts. To deal with these situations, Nuveen Asset Management has adopted procedures for allocating limited opportunities across multiple accounts.

With respect to many of its clients’ accounts, Nuveen Asset Management determines which broker to use to execute transaction orders, consistent with its duty to seek best execution of the transaction. However, with respect to certain other accounts, Nuveen Asset Management may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, Nuveen Asset Management may place separate, non-simultaneous, transactions for the Fund and other accounts which may temporarily affect the market price of the security or the execution of the transaction, or both, to the detriment of the Fund or the other accounts.

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by the portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

Fund Shares Owned by the Portfolio Manager. As of February 28, 2018, the Portfolio Manager beneficially owned (as determined pursuant to Rule 16a-1(a)(2) under the 1934 Act) shares of the Fund having values within the indicated dollar ranges.

CODE OF ETHICS

The Fund, NFALLC, Nuveen Asset Management, Nuveen Securities and other related entities have adopted a combined Code of Ethics (the “Code of Ethics”) that essentially prohibits certain of their personnel, including the Fund’s Portfolio Manager, from engaging in personal investments that compete or interfere with, or attempt to take advantage of a client’s, including the Fund’s, anticipated or actual portfolio transactions, and are designed to assure that the interests of clients, including Fund shareholders, are placed before the interests of personnel in connection with personal investment transactions. Personnel subject to the Code of Ethics may purchase shares of the Fund subject to the restrictions set forth in the Code of Ethics. While personnel subject to the Code of Ethics may generally invest in securities in which the Fund may also invest, portfolio managers of municipal bond funds, such as the Fund, may not do so. A text-only version of the Code of Ethics of the Fund, NFALLC, Nuveen Asset Management, and Nuveen Securities can be viewed online or downloaded from the EDGAR Database on the SEC’s internet web site at www.sec.gov. You may also review and copy the Code of Ethics by visiting the SEC’s Public Reference Room in Washington, DC. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 202-551-8090. In addition, copies of the Code of Ethics may be obtained, after mailing the appropriate duplicating fee, by writing to the SEC’s Public Reference Section, 100 F Street, N.E., Washington, DC 20549-0102 or by e-mail request at publicinfo@sec.gov.

PROXY VOTING POLICIES

The Fund invests its assets generally in municipal securities. On rare occasions the Fund may acquire, directly or through a special purpose vehicle, equity securities of certain issuers whose securities the Fund already owns when such securities have deteriorated or are expected shortly to deteriorate significantly in credit quality. The purpose of acquiring equity securities generally will be to acquire control of the municipal bond issuer and to seek to prevent the credit deterioration or facilitate the liquidation or other workout of the distressed issuer’s credit problem. In the course of exercising control of a distressed municipal issuer, Nuveen Asset Management may pursue the Fund’s interests in a variety of ways, which may entail negotiating and executing consents, agreements and other arrangements, and otherwise influencing the management of the issuer. Nuveen Asset Management does not consider such activities proxy voting for purposes of Rule 206(4)-6 under the Investment Advisers Act of 1940, as amended, but nevertheless provides reports to the Fund’s Board on its control activities on a quarterly basis.

In the rare event that a municipal issuer held by the Fund were to issue a proxy, or that the Fund were to receive a proxy issued by a cash management security, Nuveen Asset Management would either engage an independent third party to determine how the proxy should be voted or vote the proxy with the consent, or based on the instructions, of the Fund’s Board or its representative. In the case of a conflict of interest, the proxy would be submitted to the Fund’s Board to determine how the proxy should be voted. A member of Nuveen Asset Management’s legal department would oversee the administration of the voting, and ensure that records were maintained in accordance with Rule 206(4)-6, reports were filed with the SEC on Form N-PX, and the results provided to the Fund’s Board and made available to shareholders as required by applicable rules. If applicable, information regarding how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge, upon request, by calling (800) 257-8787 or from the Fund’s website at http://www.nuveen.com, and on the SEC’s website at http://www.sec.gov.

PORTFOLIO TRANSACTIONS AND BROKERAGE

Subject to the supervision of the Board, Nuveen Asset Management is responsible for decisions to purchase and sell securities for the Fund, the negotiation of the prices to be paid and the allocation of transactions among various dealer firms. Transactions on stock exchanges involve the payment by the Fund of brokerage commissions. There generally is no stated commission in the case of securities traded in the over-the-counter (“OTC”) market but the price paid by the Fund usually includes an undisclosed dealer commission or mark-up. Transactions in the OTC market can also be placed with broker-dealers who act as agents and charge brokerage commissions for effecting OTC transactions. The Fund may place its OTC transactions either directly with principal market makers, or with broker-dealers if that is consistent with Nuveen Asset Management’s obligation to obtain best qualitative execution. In certain instances, the Fund may make purchases of underwritten issues at prices that include underwriting fees.

Portfolio securities may be purchased directly from an underwriter or in the OTC market from the principal dealers in such securities, unless it appears that a better price or execution may be obtained through other means. Portfolio securities will not be purchased from Nuveen Investments or its affiliates or affiliates of NFALLC except in compliance with the 1940 Act.

It is Nuveen Asset Management’s policy to seek the best execution under the circumstances of each trade. Nuveen Asset Management will evaluate price as the primary consideration, with the financial condition, reputation and responsiveness of the dealer considered secondary in determining best execution. Given the best execution obtainable, it will be Nuveen Asset Management’s practice to select dealers that, in addition, furnish research information (primarily credit analyses of issuers and general economic reports) and statistical and other services to Nuveen Asset Management. It is not possible to place a dollar value on information and statistical and other services received from dealers. Since it is only supplementary to Nuveen Asset Management’s own research efforts, the receipt of research information is not expected to reduce significantly Nuveen Asset Management’s expenses. While Nuveen Asset Management will be primarily responsible for the placement of the business of the Fund, Nuveen Asset Management’s policies and practices in this regard must be consistent with the foregoing and will, at all times, be subject to review by the Board of the Fund.

Nuveen Asset Management may manage other investment accounts and investment companies for other clients that may invest in the same types of securities as the Fund and that may have investment objectives similar to those of the Fund. Nuveen Asset Management seeks to allocate portfolio transactions equitably whenever concurrent decisions are made to purchase or sell assets or securities by the Fund and another advisory account. If an aggregated order cannot be filled completely, allocations will generally be made on a pro rata basis. An order may not be allocated on a pro rata basis where, for example (i) consideration is given to portfolio managers who have been instrumental in developing or negotiating a particular investment; (ii) consideration is given to an account with specialized investment policies that coincide with the particulars of a specific investment; (iii) pro rata allocation would result in odd-lot or de minimis amounts being allocated to a portfolio or other client; or (iv) where Nuveen Asset Management reasonably determines that departure from a pro rata allocation is advisable. There may also be instances where the Fund will not participate at all in a transaction that is allocated among other accounts. While these allocation procedures could have a detrimental effect on the price or amount of the securities available to the Fund from time to time, it is the opinion of the Board that the benefits available from Nuveen Asset Management’s management outweigh any disadvantage that may arise from Nuveen Asset Management’s larger management activities and its need to allocate securities.

Substantially all of the Fund’s trades are effected on a principal basis. The following table sets forth the aggregate amount of brokerage commissions paid by the Fund for the last three fiscal years:


	Brokerage Commissions Paid
Fiscal year ended February 29, 2016	$	—
Fiscal year ended February 28, 2017	$	—
Fiscal year ended February 28, 2018	$	—

During the fiscal year ended February 28, 2018, the Fund did not pay commissions to brokers in return for research services or hold any securities of its regular broker-dealers.

NET ASSET VALUE

The Fund’s NAV per share is determined as of the close of regular session trading (normally 4:00 p.m., Eastern Time) on each day the New York Stock Exchange (“NYSE”) is open for business. NAV is calculated by taking the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of shares outstanding. The result, rounded to the nearest cent, is the NAV per share. All valuations are subject to review by the Fund’s Board or its delegate.

DISTRIBUTIONS

The Fund pays regular monthly distributions to Common Shareholders at a level rate (stated in terms of a fixed cents per share of Common Shares dividend rate) that reflects the past and projected performance of the Fund. Distributions can only be made from net investment income after paying any accrued dividends to Preferred Shareholders, or interest and required principal payments on borrowings.

To permit the Fund to maintain a more stable monthly distribution, the Fund may from time to time distribute less than the entire amount of net investment income earned in a particular period. Such undistributed net investment income would be available to supplement future distributions, including distributions that might otherwise have been reduced by a decrease in the Fund’s monthly net income due to fluctuations in investment income or expenses, an increase in interest payments on borrowings, or due to an increase in the dividend rate on the Fund’s outstanding Preferred Shares. As a result, the distributions paid by the Fund for any particular period may be more or less than the amount of net investment income actually earned by the Fund during such period. However, the Fund intends to maintain distributions of net investment income for any period in amounts sufficient to continue to qualify for treatment under Subchapter M of the Code as a RIC (as explained more fully below in “Tax Matters”). Undistributed net investment income will be added to the Fund’s NAV and, correspondingly, distributions from undistributed net investment income will be deducted from the Fund’s NAV.

As explained more fully below in “Tax Matters,” at least annually, the Fund intends to distribute to Common Shareholders any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) after paying any interest and required principal payments on borrowings and making any redemption or liquidation payments to Preferred Shareholders or, alternatively, to retain all or a portion of the year’s net

capital gain. The Fund will pay federal income tax on any net capital gain not used to pay distributions to shareholders. Each Common Shareholder of record as of the end of the Fund’s taxable year will include in income for federal income tax purposes, as long-term capital gain, his or her share of the retained gain, will be deemed to have paid his or her proportionate share of tax paid by the Fund, and will be entitled to an income tax credit or refund for that share of the tax.

For tax purposes, the Fund is currently required to allocate net capital gain and other taxable income, if any, between Common Shares and Preferred Shares in proportion to total dividends paid to each class for the year in which such net capital gain or other taxable income is realized. For information relating to the impact of the issuance of Preferred Shares on the distributions made by the Fund to Common Shareholders, see the Fund’s Prospectus under “Use of Leverage.”

If Preferred Shares are outstanding, the Fund may not declare any cash dividend or other distribution on its Common Shares unless at the time of such declaration (1) all accumulated dividends on the preferred shares have been paid, (2) all interest and required principal on borrowings has been paid, (3) the NAV of the Fund’s portfolio (determined after deducting the amount of such dividend or other distribution) is at least 200% of the liquidation value of any outstanding preferred shares and (4) the NAV of the Fund’s portfolio (determined after deducting the amount of such dividend or other distribution) is at least 300% of the value of the Fund’s borrowings. These limitations on the Fund’s ability to make distributions on its Common Shares could under certain circumstances impair the ability of the Fund to maintain its qualification for treatment as a RIC.

DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund’s Dividend Reinvestment Plan (the “Plan”), you may elect to have all dividends, including any capital gain dividends, on your Common Shares automatically reinvested by the Plan Agent (defined below) in additional Common Shares under the Plan. You may elect to participate in the Plan by contacting Nuveen Investor Services at (800) 257-8787. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you or your brokerage firm by Computershare Inc., as dividend paying agent (the “Plan Agent”).

Under the Plan, the number of Common Shares you will receive will be determined as follows:

(1)

If Common Shares are trading at or above NAV at the time of valuation, the Fund will issue new shares at the then current market price;

(2)

If Common Shares are trading below NAV at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the NYSE or elsewhere, for the participants’ accounts. It is possible that the market price for Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date. Interest will not be paid on any uninvested cash payments; or

(3)

If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below NAV, but the Fund’s shares subsequently trade at or above their NAV before the Plan Agent is able to

complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares’ NAV or 95% of the shares’ market value.

Common Shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all Common Shares you have received under the Plan. The Plan Agent maintains all shareholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Upon a repurchase of your shares, the Fund (or its administrative agent) may be required to report to the IRS and furnish to you cost basis and holding period information for the Fund’s shares purchased on or after January 1, 2012 (“covered shares”).

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due, if any, upon receiving dividends and distributions.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained from ComputerShare, P.O. Box 505000, Louisville, Kentucky, 40233-5000, (800) 257-8787.

PLAN OF DISTRIBUTION

The Fund may sell the Common Shares offered under the Prospectus and this SAI through

•

at-the-market transactions;

•

underwriting syndicates; and

•

privately negotiated transactions.

The Fund will bear the expenses of the offering, including but not limited to, the expenses of preparation of the Prospectus and this SAI for the offering and the expense of counsel and auditors in connection with the offering.

Distribution Through At-the-Market Transactions

The Fund has entered into a distribution agreement with Nuveen Securities (the “Distribution Agreement”), which has been filed as an exhibit to the Registration Statement of which this SAI is a part. Subject to the terms and conditions of the Distribution Agreement, the Fund may from time to time issue and sell its Common Shares through Nuveen Securities to certain broker-dealers which have entered into selected dealer agreements with Nuveen Securities. Currently, Nuveen Securities has entered into a Selected Dealer Agreement (the “Selected Dealer Agreement”) with UBS Securities LLC (“UBS”) pursuant to which UBS acts as Nuveen Securities’ sub-placement agent with respect to at-the-market offerings of Common Shares. The Selected Dealer Agreement has been filed as an exhibit to the Registration Statement of which this SAI forms a part. Subject to the terms and conditions of the Distribution Agreement, the Fund may from time to time issue and sell its Common Shares through Nuveen Securities to certain broker-dealers which have entered into selected dealer agreements with Nuveen Securities.

The offering of Common Shares pursuant to the Distribution Agreement will terminate upon the earlier of (i) the sale of all Common Shares subject thereto or (ii) termination of the Distribution Agreement. The Fund and Nuveen Securities each have the right to terminate the Distribution Agreement in its discretion at any time. The Fund currently intends to distribute the shares offered pursuant to the Prospectus and this SAI primarily through at-the-market transactions, although from time to time it may also distribute shares through an underwriting syndicate or a privately negotiated transaction. To the extent shares are distributed other than through at-the-market transactions, the Fund will file a supplement to the Prospectus and this SAI describing such transactions.

The Fund’s closing price on the NYSE on April 26, 2018 was $13.32.

Distribution Through Underwriting Syndicates

The Fund from time to time may issue additional Common Shares through a syndicated secondary offering. In order to limit the impact on the market price of the Fund’s Common Shares, underwriters will market and price the offering on an expedited basis (e.g., in an overnight or similarly abbreviated offering period). The Fund will launch a syndicated offering on a day, and upon terms, mutually agreed upon between the Fund, Nuveen Securities, one of the Fund’s underwriters, and the underwriting syndicate.

The Fund will offer its shares at a price equal to a specified discount of up to 5% from the closing market price of the Fund’s Common Shares on the day prior to the offering date. The applicable discount will be negotiated by the Fund and Nuveen Securities in consultation with the underwriting syndicate on a transaction-by-transaction basis. The Fund will compensate the underwriting syndicate out of the proceeds of the offering based upon a sales load of up to 4% of the gross proceeds of the sale of Common Shares. The minimum net proceeds per share to the Fund will not be less than the greater of (i) the Fund’s latest NAV per Common Share or (ii) 91% of the closing market price of the shares of the Fund’s Common Shares on the day prior to the offering date.

Distribution Through Privately Negotiated Transactions

Common Shares issued by the Fund through privately negotiated transactions will be issued at a price equal to the greater of (i) the NAV per share of the Fund’s Common Shares or (ii) at a discount ranging from 0% to 5% of the average daily closing market price of the Fund’s Common Shares at the close of business on the two business days preceding the date upon which Common Shares are sold pursuant to the privately negotiated transaction. The applicable discount will be determined by the Fund on a transaction-by-transaction basis.

The principal business address of Nuveen Securities is 333 West Wacker Drive, Suite 3300, Chicago, Illinois 60606.

DESCRIPTION OF SHARES

Common Shares

The Declaration of Trust (the “Declaration”) authorizes the issuance of an unlimited number of Common Shares. The Common Shares being offered have a par value of $0.01 per share and, subject to the rights of holders of preferred shares, if issued, and borrowings, if incurred have equal rights to the payment of dividends and the distribution of assets upon liquidation of the Fund. The Common Shares being offered will, when issued, be fully paid and, subject to matters discussed under “Certain Provisions in the Declaration of Trust and By-Laws,” non-assessable, and will have no pre-emptive or conversion rights or rights to cumulative voting. Each Common Share has one vote with respect to matters upon which a shareholder vote is required, consistent with the requirements of the 1940 Act and the rules promulgated thereunder, and will vote together as a single class. Whenever the fund incurs borrowings and/or preferred shares are outstanding, Common Shareholders will not be entitled to receive any cash distributions from the Fund unless all interest on such borrowings has been paid and all accrued dividends on preferred shares have been paid, unless asset coverage (as defined in the 1940 Act) with respect to any borrowings would be at least 300% after giving effect to the distributions and asset coverage (as defined in the 1940 Act) with respect to Preferred Shares would be at least 200% after giving effect to the distributions. See “Preferred Shares” below.

Preferred Shares

Under the 1940 Act, the Fund is not permitted to issue “senior securities” that are Preferred Shares if, immediately after the issuance of Preferred Shares, the asset coverage ratio with respect to such shares would be less than 200%. See “Leverage.” Additionally, the Fund will generally not be permitted to purchase any of its Common Shares or declare dividends (except a dividend payable in Common Shares) or other distributions on its Common Shares unless, at the time of such purchase or declaration, the asset coverage ratio with respect to such Preferred Shares, after taking into account such purchase or distribution, is at least 200%.

Distribution Preference. Preferred Shares have complete priority over Common Shares as to distribution of assets.

Holders of Preferred Shares, voting as a separate class, will be entitled to elect two of the Fund’s trustees (following the establishment of the Fund by an initial trustee, the Declaration provides for a total of no less than two and no more than 12 trustees). The remaining trustees will be elected by Common Shareholders and holders of Preferred Shares, voting together as a single class. In the unlikely event that two full years of accrued dividends are unpaid on the Preferred Shares the holders of all outstanding Preferred Shares voting as a separate class, will be entitled to elect a majority of the Fund’s trustees until all dividends in arrears have been paid or declared and set apart for payment. In order for the Fund to take certain actions or enter into certain transactions, a separate class vote of holders of Preferred Shares would be required, in addition to the single class vote of the holders of Preferred Shares, and Common Shares. See “Certain Provisions in the Declaration of Trust.”

Redemption, Purchase and Sale of Preferred Shares. The terms of any Preferred Share offering provides that they may be redeemed by the issuer at certain times, in whole or in part, at the original purchase price per share plus accumulated dividends. Any redemption or purchase of Preferred Shares by the Fund will reduce the leverage applicable to Common Shares, while any issuance of shares by the Fund would increase such leverage.

CERTAIN PROVISIONS IN THE DECLARATION OF TRUST AND BY-LAWS

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Fund. However, the Declaration contains an express disclaimer of shareholder liability for debts or obligations of the Fund and requires that notice of such limited liability be given in each agreement, obligation or instrument entered into or executed by the Fund or the trustees. The Declaration further provides for indemnification out of the assets and property of the Fund for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund would be unable to meet its obligations. The Fund believes that the likelihood of such circumstances is remote.

Anti-Takeover Provisions. The Declaration and By-Laws include provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. The By-Laws require the Board be divided into three classes with staggered terms. See “Management of the Fund” in this SAI. This provision of the By-Laws could delay for up to two years the replacement of a majority of the Board. If preferred shares are issued, holders of preferred shares, voting as a separate class, will be entitled to elect two of the Fund’s trustees. In addition, the Declaration requires a vote by holders of at least two-thirds of the Common Shares and Preferred Shares, voting together as a single class, except as described below, to authorize (1) a conversion of the Fund from a closed-end to an open-end investment company, (2) a merger or consolidation of the Fund, or a series or class of the Fund, with any corporation, association, trust or other organization or a reorganization of the Fund, or a series or class of the Fund, (3) a sale, lease or transfer of all or substantially all of the Fund’s assets (other than in the regular course of the Fund’s investment activities), (4) in certain

circumstances, a termination of the Fund, or a series or class of the Fund or (5) removal of trustees by shareholders (except at the end of a trustee’s term), and then only for cause, unless, with respect to (1) through (4), such transaction has already been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-Laws, in which case the affirmative vote of the holders of at least a majority of the Fund’s Common Shares and Preferred Shares, outstanding at the time, voting together as a single class, is required, provided, however, that where only a particular class or series is affected (or, in the case of removing a trustee, when the trustee has been elected by only one class), the required vote only by the applicable class or series will be required. Approval of shareholders is not required, however, for any transaction, whether deemed a merger, consolidation, reorganization or otherwise whereby the Fund issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. In the case of the conversion of the Fund to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan of reorganization which adversely affects the holders of Preferred Shares the action in question will also require the affirmative vote of the holders of at least two-thirds of the Fund’s Preferred Shares outstanding at the time, voting as a separate class, or, if such action has been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-Laws, the affirmative vote of the holders of at least a majority of the Fund’s Preferred Shares outstanding at the time, voting as a separate class. None of the foregoing provisions may be amended except by the vote of at least two-thirds of the Common Shares and Preferred Shares voting together as a single class. The votes required to approve the conversion of the Fund from a closed-end to an open-end investment company or to approve transactions constituting a plan of reorganization which adversely affects the holders of Preferred Shares are higher than those required by the 1940 Act. The Board believes that the provisions of the Declaration relating to such higher votes are in the best interest of the Fund and its shareholders. Note, the Fund’s staggered Board could delay for up to two years the replacement of a majority of the Board. Reference should be made to the Declaration on file with the SEC for the full text of these provisions.

REPURCHASE OF FUND SHARES; CONVERSION TO OPEN-END FUND

The Fund is a closed-end investment company and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the Common Shares will trade in the open market at a price that will be a function of several factors, including distribution levels (which are in turn affected by expenses), NAV, call protection, distribution stability, portfolio credit quality relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because shares of a closed-end investment company may frequently trade at prices lower than NAV, the Fund’s Board has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from NAV in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at NAV, or the conversion of the Fund to an open-end investment company. There can be no assurance, however, that the Board will decide to take any of these actions, or that share repurchases or tender offers, if undertaken, will reduce market discount. On August 1, 2017, the Fund’s Board renewed the Fund’s open market share repurchase program under which the Fund may repurchase up to 10% of its Common Shares. Since the inception of the Fund’s share repurchase program through April 26, 2018, the Fund has not repurchased any Common shares under the program.

Notwithstanding the foregoing, at any time if the Fund has Preferred Shares outstanding the Fund may not purchase, redeem or otherwise acquire any of its Common Shares unless (1) all accrued preferred shares dividends have been paid and (2) at the time of such purchase, redemption or acquisition, the NAV of the

Fund’s portfolio (determined after deducting the acquisition price of Common Shares) is at least 200% of the liquidation value of the outstanding preferred shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon). The staff of the SEC currently requires that any tender offer made by a closed-end investment company for its shares must be at a price equal to the NAV of such shares at the close of business on the last day of the tender offer. Any service fees incurred in connection with any tender offer made by the Fund will be borne by the Fund and will not reduce the stated consideration to be paid to tendering shareholders.

Although the decision to take action in response to a discount from NAV will be made by the Board of the Fund at the time it considers such issue, it is the Board’s present policy, which may be changed by the Board, not to authorize repurchases of Common Shares or a tender offer for such shares if (1) such transactions, if consummated, would (a) result in the delisting of the Common Shares from the NYSE, or (b) impair the Fund’s eligibility for treatment as a RIC under the Code or impair the Fund’s status as a registered closed-end investment company under the 1940 Act; (2) the Fund would not be able to liquidate portfolio securities in an orderly manner and consistent with the Fund’s investment objectives and policies in order to repurchase shares; or (3) there is, in the Board’s judgment, any (a) material legal action or proceeding instituted or threatened challenging such transactions or otherwise materially adversely affecting the Fund, (b) general suspension of or limitation on prices for trading securities on the NYSE, (c) declaration of a banking moratorium by Federal or state authorities or any suspension of payment by United States or state banks in which the Fund invests, (d) material limitation affecting the Fund or the issuers of its portfolio securities by federal or state authorities on the extension of credit by lending institutions or on the exchange of foreign currency, (e) commencement of war, armed hostilities or other international or national calamity directly or indirectly involving the United States, or (f) other event or condition which would have a material adverse effect (including any adverse tax effect) on the Fund or its shareholders if shares were repurchased. The Board of the Fund may in the future modify these conditions in light of experience.

Conversion to an open-end company would require the approval of the holders of at least two-thirds of the Fund’s Common Shares and Preferred Shares outstanding at the time, voting together as a single class, and of the holders of at least two-thirds of the Fund’s Preferred Shares outstanding at the time, voting as a separate class, provided however, that such separate class vote shall be a majority vote if the action in question has previously been approved, adopted or authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or By-Laws. See the Prospectus under “Certain Provisions in the Declaration of Trust” for a discussion of voting requirements applicable to conversion of the Fund to an open-end company. If the Fund converted to an open-end company, it would be required to redeem all preferred shares then outstanding, and the Fund’s common shares would no longer be listed on the NYSE. Shareholders of an open-end investment company may require the company to redeem their shares on any business day (except in certain circumstances as authorized by or under the 1940 Act) at their NAV, less such redemption charge, if any, as might be in effect at the time of redemption. In order to avoid maintaining large cash positions or liquidating favorable investments to meet redemptions, open-end companies typically engage in a continuous offering of their shares. Open-end companies are thus subject to periodic asset in-flows and out-flows that can complicate portfolio management. The Board of the Fund may at any time propose conversion of the Fund to an open-end company depending upon their judgment as to the advisability of such action in light of circumstances then prevailing.

The repurchase by the Fund of its shares at prices below NAV would result in an increase in the NAV of those shares that remain outstanding. However, there can be no assurance that share repurchases or tenders at or

below NAV would result in the Fund’s shares trading at a price equal to their NAV. Nevertheless, the fact that the Fund’s shares may be the subject of repurchase or tender offers at NAV from time to time, or that the Fund may be converted to an open-end company, may reduce any spread between market price and NAV that might otherwise exist.

In addition, a purchase by the Fund of its Common Shares would decrease the Fund’s total assets which would likely have the effect of increasing the Fund’s expense ratio. Any purchase by the Fund of its Common Shares at a time when Preferred Shares are outstanding will increase the leverage applicable to the outstanding Common Shares then remaining.

TAX MATTERS

The following is intended to be a general summary of certain U.S. federal income tax consequences of investing, holding and disposing of Common Shares of the Fund. It is not intended to be a complete discussion of all such federal income tax consequences, nor does it purport to deal with all categories of investors (including investors in Common Shares with large positions in the Fund). Investors are advised to consult with their own tax advisors before investing in the Fund.

The Fund has elected and intends to qualify each year to be treated as a RIC under Subchapter M of the Code. The Fund also intends to satisfy conditions under which dividends on Common Shares attributable to interest on municipal securities (as defined above) are exempt from federal income tax in the hands of owners of such stock, subject to the possible application of the federal alternative minimum tax.

To qualify under Subchapter M of the Code for treatment as a RIC, the Fund must, among other things: (a) distribute to its shareholders each year at least 90% of the sum of (i) its investment company taxable income (as that term is defined in the Code, determined without regard to the deduction for dividends paid) and (ii) its net tax-exempt income (the excess of its gross tax-exempt interest income over certain disallowed deductions) (b) derive at least 90% of its gross income (including income on municipal securities exempt from regular federal income tax) for each taxable year from dividends, interest (including interest income on municipal securities exempt from regular income tax), payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including gains from options, futures and forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from an interest in a qualified publicly traded partnership (as defined in the Code), and (c) diversify its holdings so that, at the end of each quarter of the Fund’s taxable year (i) at least 50% of the market value of the Fund’s assets is represented by cash, cash items, U.S. government securities, securities of other RICs, and other securities, with these other securities limited, with respect to any one issuer, to an amount

not greater in value than 5% of the Fund’s total assets, and to not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the market value of the Fund’s assets is invested, including through companies in which the Fund owns a 20% or more voting stock interest, in the securities of any one issuer (other than U.S. government securities or securities of other RICs), the securities of two or more issuers (other than securities of other RICs) controlled by the Fund and engaged in the same, similar or related trades or businesses, or the securities of one or more qualified publicly traded partnerships. To meet these requirements, the Fund may need to restrict its use of certain of the investment techniques described under “Investment Policies and Techniques” and “Other Investment Policies and Techniques” above.

If the Fund fails to satisfy the qualifying income or diversification requirements in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period of time. In order to be eligible for the relief provisions with respect to a failure to meet the diversification requirements, the Fund may be required to dispose of certain assets. If these relief provisions are not available to the Fund and it fails to qualify for treatment as a RIC for a taxable year, the Fund will be taxable at regular corporate tax rates (which the Tax Act reduced to 21%). In such an event, all distributions (including capital gains distributions and distributions derived from interest on municipal securities) will be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits, subject to the dividends-received deduction for corporate shareholders and to the tax rates applicable to qualified dividend income distributed to individuals. Distributions in excess of the Fund’s current and accumulated earnings and profits would be treated first as a tax-free return of capital to the extent of the holder’s adjusted tax basis in the shares (reducing that basis accordingly), and any remaining distributions would generally be treated as a capital gain. To requalify for treatment as a RIC in a subsequent taxable year, the Fund would be required to satisfy the RIC qualification requirements for that year and to distribute any earnings and profits from any year in which the Fund failed to qualify for tax treatment as a RIC. In addition, if the Fund failed to qualify as a RIC for a period greater than two taxable years, it would generally be required to pay a Fund-level tax on certain net built-in gains recognized with respect to certain of its assets upon a disposition of such assets within five years of qualifying as a RIC in a subsequent year.

A RIC that fails to distribute, by the close of each calendar year, an amount at least equal to the sum of 98% of its ordinary taxable income for such year and 98.2% of its capital gain net income for the one-year period ending October 31 in such year, plus any shortfalls from the prior year’s required distribution, is liable for a nondeductible 4% federal excise tax on the excess of the required distribution for such calendar year over the distributed amount for such calendar year. To avoid the imposition of this excise tax, the Fund generally intends to make the required distributions of its ordinary taxable income, if any, and its capital gain net income, to the extent possible, by the close of each calendar year.

Certain minimum NAV coverage limitations on distributions made with respect to Common Shares may under certain circumstances impair the ability of the Fund to maintain its qualification for treatment as a RIC or to pay distributions sufficient to avoid the imposition of the 4% federal excise tax.

As described in “Distributions” above, the Fund may retain for investment or otherwise use some (or all) of its net capital gain. If the Fund retains any net capital gain or taxable net investment income, it will be subject to tax at regular corporate rates on the amount retained. If the Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who, if subject to federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their shares of such undistributed amount; (ii) will be deemed to have paid their proportionate shares of the tax paid by the Fund on such undistributed amount and will be entitled to credit that amount of tax against their federal income tax liabilities, if any; and (iii) will be entitled to claim refunds to the extent the credit exceeds such liabilities. For federal income tax purposes, the tax basis of shares owned by a shareholder of the

Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the tax deemed paid by the shareholder.

The Fund intends to qualify to pay “exempt-interest” dividends, as defined in the Code, to its Common Shares by satisfying the requirement that, at the close of each quarter of its taxable year, at least 50% of the value of its total assets consists of municipal securities. Exempt-interest dividends are dividends or any part thereof (other than a capital gain dividend) paid by the Fund which are attributable to interest on municipal securities and which are so reported by the Fund. Exempt-interest dividends will be exempt from federal income tax, subject to the possible application of the federal alternative minimum tax applicable to individuals. Under the Tax Act, interest paid on a municipal bond issued after December 31, 2017 to advance or refund another municipal bond is subject to federal income tax. Insurance proceeds received by the Fund under any insurance policies in respect of scheduled interest payments on defaulted municipal bonds, as described herein, will generally be correspondingly excludable from federal gross income. In the case of non-appropriation by a political subdivision, however, there can be no assurance that payments made by the issuer representing interest on municipal lease obligations will be excludable from gross income for federal income tax purposes. See “Investment Policies and Techniques” above. Any gains of the Fund that are attributable to market discount on municipal securities are treated as ordinary income to the extent of accrued market discount on those securities.

A portion of the Fund’s expenditures that would otherwise be deductible may not be allowed as deductions by reason of the Fund’s investment in municipal securities (such disallowed portion, in general, being the same percentage of the Fund’s aggregate expenses as the percentage of the Fund’s aggregate gross income that constitutes exempt interest income from municipal securities). A similar disallowance rule also applies to interest expense paid or incurred by the Fund, if any. Any such disallowed deductions will offset the Fund’s gross exempt-interest income for purposes of calculating the dividends that the Fund can report as exempt-interest dividends. Interest on indebtedness incurred or continued to purchase or carry the Fund’s shares is not deductible to the extent the interest relates to exempt-interest dividends. Under rules used by the Internal Revenue Service (“IRS”) for determining when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of such shares.

Distributions to shareholders of net investment income received by the Fund from taxable investments, if any, including temporary taxable investments, and of net short-term capital gains realized by the Fund, if any, will be taxable to its shareholders as ordinary income. Distributions by the Fund of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss), if any, are taxable as long-term capital gain, regardless of the length of time the shareholder has owned the shares with respect to which such distributions are made. The amount of taxable income allocable to the Fund’s shares will depend upon the amount of such income realized by the Fund. Distributions of taxable income, if any, in excess of the Fund’s earnings and profits will first reduce the adjusted tax basis of a shareholder’s shares and, after that basis has been reduced to zero, will constitute capital gain to the shareholder (assuming the shares are held as capital assets). As long as the Fund qualifies as a RIC under the Code, it is not expected that any part of its distributions to shareholders from its investments will qualify for the dividends-received deduction available to corporate shareholders or as “qualified dividend income” taxable to non-corporate shareholders at reduced rates.

The IRS requires the Fund to report distributions paid with respect to its Common Shares and its Preferred Shares as consisting of a portion of each type of income distributed by the Fund. The portion of each type of income deemed received by the holders of each class of shares will be equal to the portion of total Fund dividends received by such class. Thus, the Fund will report dividends paid as exempt-interest dividends in a manner that allocates such dividends between the holders of Common Shares and the Preferred Shares, in proportion to the total dividends paid to each such class during or with respect to the taxable year, or otherwise as required by applicable law. Capital gain dividends and ordinary income dividends will also be allocated between the two classes under these rules.

The interest on private activity bonds in most instances is not federally tax-exempt to a person who is a “substantial user” of a facility financed by such bonds or a “related person” of such “substantial user.” As a result, the Fund may not be an appropriate investment for a shareholder who is considered either a “substantial user” or a “related person” within the meaning of the Code. In general, a “substantial user” of a facility includes a “nonexempt person who regularly uses a part of such facility in his trade or business.” “Related persons” are in general defined to include persons among whom there exists a relationship, either by family or business, which would result in a disallowance of losses in transactions among them under various provisions of the Code (or if they are members of the same controlled group of corporations under the Code), including a partnership and each of its partners (and certain members of their families), an S corporation and each of its shareholders (and certain members of their families) and various combinations of these and other relationships. The foregoing is not a complete description of all of the provisions of the Code covering the definitions of “substantial user” and “related person.”

Although dividends generally will be treated as distributed when paid, dividends declared in October, November or December, payable to shareholders of record on a specified date in one of those months and paid during the following January, will be treated as having been distributed by the Fund (and received by the shareholders) on December 31 of the year declared. The U.S. federal income tax status of all distributions will be reported to shareholders annually.

Although the Fund expects that under normal circumstances it will not invest in municipal securities the interest on which is subject to the federal alternative minimum tax, at times a portion of the income from municipal securities may be subject to the federal alternative minimum tax. Federal income tax law imposes an alternative minimum tax with respect to individuals, trusts and estates. Interest on certain municipal securities, such as bonds issued to make loans for housing purposes or to private entities (but not to certain tax-exempt organizations such as universities and non-profit hospitals), is included as an item of tax preference in determining the amount of a taxpayer’s alternative minimum taxable income. Under normal circumstances, the Fund invests at least 80% of its Assets in securities the interest from which is not a tax preference item. If the Fund receives income from municipal securities the interest on which is a tax preference item, a portion of the dividends paid by the Fund, although otherwise exempt from federal income tax, will be taxable to shareholders whose tax liabilities are determined under the federal alternative minimum tax. The Fund will annually provide a report indicating the percentage of the Fund’s income attributable to municipal securities and the portion thereof the interest on which is a tax preference item. Bonds issued in 2009 or 2010 generally will not be treated as private activity bonds, and interest earned on such bonds (and Fund distributions consisting of such interest) generally will not be treated as a tax preference item and generally will not result in or increase a shareholder’s liability for the federal alternative minimum tax.

The Tax Act repealed the federal alternative minimum tax for corporations for tax years beginning after December 31, 2017.

Tax-exempt income, including exempt-interest dividends paid by the Fund, is taken into account in calculating the amount of social security and railroad retirement benefits that may be subject to federal income tax.

If the Fund invests in certain pay-in-kind securities, zero coupon securities, deferred interest securities or, in general, any other securities with original issue discount (or with market discount if the Fund elects or is otherwise

required to include market discount in income currently), the Fund generally must accrue income on such investments for each taxable year, which generally will be prior to the receipt of the corresponding cash payments. However, the Fund must distribute to its shareholders, at least annually, all or substantially all of its investment company taxable income (determined without regard to the deduction for dividends paid), including such accrued income, to qualify to be treated as a RIC under the Code and avoid U.S. federal income and excise taxes.

Certain of the Fund’s investment practices are subject to special provisions of the Code that, among other things, may affect the Fund’s ability to qualify as a RIC, defer the use of certain deductions or losses of the Fund, affect the holding period of securities held by the Fund, and alter the character of the gains or losses realized by the Fund. These provisions may also require the Fund to recognize income or gain without receiving cash with which to make distributions in the amounts necessary to satisfy the requirements for maintaining RIC status and for avoiding income and excise taxes. The Fund will monitor its transactions and may make certain tax elections in order to mitigate the effect of these rules and prevent disqualification of the Fund for treatment as a RIC.

Capital losses in excess of capital gains (“net capital losses”) are not permitted to be deducted against a RIC’s net investment income. Instead, for U.S. federal income tax purposes, potentially subject to certain limitations, the Fund may carry net capital losses from any taxable year forward to offset capital gains in future years. The Fund is permitted to carry forward a net capital loss from any taxable year that began on or before December 22, 2010 to offset its capital gains, if any, for up to eight years following the year of the loss. The Fund is permitted to carry forward indefinitely a net capital loss from any taxable year that began after December 22, 2010 to offset its capital gains, if any, in years following the year of the loss. To the extent subsequent capital gains are offset by such losses, they will not result in U.S. federal income tax liability to the Fund and may not be distributed as capital gains to shareholders. Carryforwards of losses from taxable years that began after December 22, 2010 must be fully utilized before the Fund may utilize carryforwards of losses from taxable years that began on or before December 22, 2010. Generally, the Fund may not carry forward any losses other than net capital losses. Under certain circumstances, the Fund may elect to treat certain losses as though they were incurred on the first day of the taxable year immediately following the taxable year in which they were actually incurred.

As of February 28, 2018, the Fund’s tax year end, the Fund had unused capital loss carryforwards available for federal tax purposes in the amount of:


Not subject to expiration	$	7,795,582

The repurchase, sale or exchange of Common Shares normally will result in capital gain or loss to holders of Common Shares who hold their shares as capital assets. Generally a shareholder’s gain or loss will be long-term capital gain or loss if the shares have been held for more than one year even though the increase in value in such common shares may be at least partly attributable to tax-exempt interest income. Present law taxes both long-term and short-term capital gains of corporations at the same rates applicable to ordinary income. For non-corporate taxpayers, however, long-term capital gains are taxed at rates of up to 20%. Short-term capital gains and other ordinary income are taxed to non-corporate shareholders at ordinary income rates. If a shareholder sells or otherwise disposes of Common Shares before holding them for six months, any loss on the sale or disposition will be treated as a long-term capital loss to the extent of any amounts treated as distributions to the Common Shareholder of long-term capital gain (including any amount credited to the shareholder as undistributed capital gain). Any loss realized on a sale or exchange of shares of the Fund will be disallowed to the extent those shares of the Fund are replaced (including, without limitation, under the Plan) by substantially identical shares of the Fund within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares, or to the extent the shareholder enters into a contract or option to repurchase shares within such period. In that event, the basis of the replacement shares of the Fund will be adjusted to reflect the disallowed loss.

shares, the Fund (or its administrative agent) may be required to report to the IRS and furnish to you cost basis and holding period information for the Fund’s shares purchased on or after January 1, 2012 (“covered shares”).

The Fund is required in certain circumstances to withhold (as “backup withholding”) a portion of dividends (including exempt-interest dividends) and certain other payments paid to certain holders of the Fund’s shares who do not furnish to the Fund their correct taxpayer identification numbers (in the case of individuals, their social security numbers) and certain certifications, or who are otherwise subject to backup withholding. The backup withholding rate is 24%. Backup withholding is not an additional tax. Any amounts withheld from payments made to a shareholder may be refunded or credited against such shareholder’s federal income tax liability, provided the required information and forms are timely furnished to the IRS.

The Code provides that every shareholder required to file a tax return must include for information purposes on such return the amount of tax-exempt interest received during the taxable year, including any exempt-interest dividends received from the Fund.

The description of certain federal tax provisions above relates only to U.S. federal income tax consequences for shareholders who are U.S. persons, i.e., generally, U.S. citizens or residents or U.S. corporations, partnerships, trusts or estates, and who are subject to U.S. federal income tax and hold their shares as capital assets. Except as otherwise provided, this description does not address the special tax rules that may be applicable to particular types of investors, such as financial institutions, insurance companies, securities dealers, other RICs, or tax-exempt or tax-deferred plans, accounts or entities. Investors that are not U.S. persons may be subject to different U.S. federal income tax treatment, including a non-resident alien U.S. withholding tax at the rate of 30% or any lower applicable treaty rate on amounts treated as ordinary dividends from the Fund (other than certain dividends reported by the Fund as (i) interest-related dividends, to the extent such dividends are derived from the Fund’s “qualified net-interest income,” or (ii) short-term capital gain dividends, to the extent such dividends are derived from the Fund’s “qualified short-term gain”) or, in certain circumstances, unless an effective IRS Form W-8BEN or other authorized withholding certificate is on file, to backup withholding on certain other payments from the Fund. “Qualified net interest income” is the Fund’s net income derived from U.S.-source interest and OID, subject to certain exceptions and limitations. “Qualified short-term gain” generally means the excess of net short-term capital gain of the Fund for the taxable year over its net long-term capital loss, if any. Backup withholding will not be applied to payments that have been subject to the 30% (or lower applicable treaty rate) withholding tax on shareholders who are neither citizens nor residents of the United States.

Unless certain non-U.S. entities that hold Fund shares comply with IRS requirements that will generally require them to report information regarding U.S. persons investing in, or holding accounts with, such entities, a 30% withholding tax may apply to Fund distributions payable to such entities and to repurchase proceeds and certain capital gain dividends payable to such entities after December 31, 2018. A non-U.S. shareholder may be exempt from the withholding described in this paragraph under an applicable intergovernmental agreement between the U.S. and a foreign government, provided that the shareholder and the applicable foreign government comply with the terms of such agreement. Exempt-interest dividends may be exempt from this withholding tax.

The foregoing is a general summary of certain provisions of the Code and regulations thereunder presently in effect as they directly govern the federal income taxation of the Fund and its shareholders. These provisions are subject to change by legislative or administrative action, and any such change may be retroactive. Moreover, the foregoing does not address many of the factors that may be determinative of whether an investor will be

liable for the alternative minimum tax. Stockholders are advised to consult their own tax advisors for more detailed information concerning the federal, foreign, state and local tax consequences of purchasing, holding and disposing of Fund shares.

CALIFORNIA TAX MATTERS

OTHER STATE AND LOCAL TAX MATTERS

While exempt-interest dividends are exempt from regular federal and California income taxes, they may not be exempt from other state or local income or other taxes. Some states exempt from state income tax that portion of any exempt-interest dividend that is derived from interest a RIC receives on its holdings of securities of that state and its political subdivisions and instrumentalities. Therefore, the Fund will report annually to its shareholders the percentage of interest income the Fund earned during the preceding year on tax-exempt obligations and the Fund will indicate, on a state-by-state basis, the source of this income. Shareholders are advised to consult with their own tax advisors for more detailed information concerning California tax matters or the tax laws of their state and locality of residence. Please refer to the SAI for more detailed information.

APPENDIX A

Ratings of Investments

S&P Global Ratings

The following rating definitions are for long-term and short-term credit ratings for both issuer and issue ratings. These types of credit ratings cover the broadest set of credit risk factors and are not limited in scope. Some refer to these as the “traditional” credit ratings.

A. Issue Credit Ratings

An S&P Global Ratings issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects S&P Global Ratings’ view of the obligor’s capacity and willingness to meet its financial commitments as they come due, and this opinion may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

Issue credit ratings can be either long-term or short-term. Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. Medium-term notes are assigned long-term ratings.

LONG-TERM ISSUE CREDIT RATINGS

Long-term issue credit ratings are based, in varying degrees, on S&P Global Ratings’ analysis of the following considerations:

• The likelihood of payment—the capacity and willingness of the obligor to meet its financial commitments on an obligation in accordance with the terms of the obligation;

• The nature and provisions of the financial obligation, and the promise we impute; and

• The protection afforded by, and relative position of, the financial obligation in the event of a bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors’ rights.

Issue ratings are an assessment of default risk but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)

AAA

An obligation rated ‘AAA’ has the highest rating assigned by S&P Global Ratings. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

An obligation rated ‘AA’ differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A-1

An obligation rated ‘A’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

BBB

An obligation rated ‘BBB’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor’s capacity to meet its financial commitment on the obligation.

BB, B, CCC, CC, and C

Obligations rated ‘BB’, ‘B’, ‘CCC’, ‘CC’, and ‘C’ are regarded as having significant speculative characteristics. ‘BB’ indicates the least degree of speculation and ‘C’ the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

An obligation rated ‘BB’ is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitments on the obligation.

An obligation rated ‘B’ is more vulnerable to nonpayment than obligations rated ‘BB’, but the obligor currently has the capacity to meet its financial commitments on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.

CCC

An obligation rated ‘CCC’ is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitments on the obligation.

An obligation rated ‘CC’ is currently highly vulnerable to nonpayment. The ‘CC’ rating is used when a default has not yet occurred but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.

An obligation rated ‘C’ is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared with obligations that are rated higher.

An obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D’ rating also will be used upon

A-2

the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.

This indicates that no rating has been requested, that there is insufficient information on which to base a rating, or that S&P Global Ratings does not rate a particular obligation as a matter of policy.

Plus (+) or minus (-)

The ratings from ‘AA’ to ‘CCC’ may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

Short-Term Issue Credit Ratings

A-1

A short-term obligation rated ‘A-1’ is rated in the highest category by S&P Global Ratings. The obligor’s capacity to meet its financial commitments on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2

A short-term obligation rated ‘A-2’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

A-3

A short-term obligation rated ‘A-3’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken an obligor’s capacity to meet its financial commitments on the obligation.

A short-term obligation rated ‘B’ is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties that could lead to the obligor’s inadequate capacity to meet its financial commitments.

A short-term obligation rated ‘C’ is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation.

A short-term obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.

A-3

Dual Ratings

Dual ratings may be assigned to debt issues that have a put option or demand feature. The first component of the rating addresses the likelihood of repayment of principal and interest as due, and the second component of the rating addresses only the demand feature. The first component of the rating can relate to either a short-term or long-term transaction and accordingly use either short-term or long-term rating symbols. The second component of the rating relates to the put option and is assigned a short-term rating symbol (for example, ‘AAA/A-1+’ or ‘A-1+/A-1’). With U.S. municipal short-term demand debt, the U.S. municipal short-term note rating symbols are used for the first component of the rating (for example, ‘SP-1+/A-1+’).

Moody’s Investors Service, Inc.

A brief description of the applicable Moody’s Investors Service, Inc. (“Moody’s”) rating symbols and their meanings (as published by Moody’s) follows:

Municipal Bonds

Aaa

Bonds that are rated ‘Aaa’ are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Bonds mat are rated ‘Aa’ are judged to be of high quality by all standards. Together with the ‘Aaa’ group they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in ‘Aaa’ securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present mat make the long-term risks appear somewhat larger than in ‘Aaa’ securities.

Bonds that are rated ‘A’ possess many favorable investment attributes and are to be considered as upper medium grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present that suggest a susceptibility to impairment sometime in the future.

Baa

Bonds that are rated ‘Baa’ are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well.

Bonds that are rated ‘Ba’ are judged to have speculative elements; their future cannot be considered as well assured. Often the protection of interest and principal payments may be very moderate and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

A-4

Bonds that are rated ‘B’ generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

Caa

Bonds that are rated ‘Caa’ are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

Bonds that are rated ‘Ca’ represent obligations that are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

Bonds that are rated ‘C’ are the lowest rated class of bonds, and issues so rated can be regarded as having extremely poor Prospects of ever attaining any real investment standing.

#(hatchmark): Represents issues that are secured by escrowed funds held in cash, held in trust, invested and reinvested in direct, non-callable, non-prepayable United States government obligations or non-callable, non-prepayable obligations unconditionally guaranteed by the U.S. Government, Resolution Funding Corporation debt obligations.

Con. (...): Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operation experience, (c) rentals that begin when facilities are completed, or (d) payments to which some other limiting condition attaches. The parenthetical rating denotes probable credit stature upon completion of construction or elimination of the basis of the condition.

(P): When applied to forward delivery bonds, indicates the rating is provisional pending delivery of the bonds. The rating may be revised prior to delivery if changes occur in the legal documents or the underlying credit quality of the bonds.

Note: Moody’s applies numerical modifiers 1,2 and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates mat the issue ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks in the lower end of its generic rating category.

Short-Term Loans

MIG 1/VMIG 1

This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2/VMIG 2

This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

A-5

MIG 3/VMIG 3

This designation denotes favorable quality. All security elements are accounted for but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

MIG 4/VMIG 4

This designation denotes adequate quality. Protection commonly regarded as required of an investment security is present and although not distinctly or predominantly speculative, there is specific risk.

This designation denotes speculative quality. Debt instruments in this category lack margins of protection.

Commercial Paper

Issuers (or supporting institutions) rated Prime-1 have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will normally be evidenced by the following characteristics:

•

Leading market positions in well-established industries.

•

High rates of return on funds employed.

•

Conservative capitalization structures with moderate reliance on debt and ample asset protection.

•

Broad margins in earnings coverage of fixed financial charges and high internal cash generation.

•

Well-established access to a range of financial markets and assured sources of alternate liquidity.

Issuers (or supporting institutions) rated Prime-2 have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above but to a lesser degree. Earnings trends and coverage ratios, while sound, may be more subject to variation than is the case for Prime-2 securities. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Issuers (or supporting institutions) rated Prime-3 have an acceptable ability for repayment of senior short-term debt obligations. The effect of industry characteristics and market composition may be more pronounced. Variability in earnings and profitability may result in changes in the level of debt protection measurements and the requirement for relatively high financial leverage. Adequate alternate liquidity is maintained.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

Fitch Ratings

A brief description of the applicable Fitch Ratings (“Fitch”) ratings symbols and meanings (as published by Fitch) follows:

Long-Term Credit Ratings

Investment Grade

AAA

Highest credit quality. ‘AAA’ ratings denote the lowest expectation of default risk. They are assigned only in case of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

A-6

Very high credit quality. ‘AA’ ratings denote expectations of very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

High credit quality. ‘A’ ratings denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.

BBB

Good credit quality. ‘BBB’ ratings indicate that expectations of default risk are currently low. The capacity for payment of financial commitments is considered adequate, but adverse business or economic conditions are more likely to impair this capacity.

Speculative. ‘BB’ ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists that supports the servicing of financial commitments.

Highly Speculative. ‘B’ ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.

CCC

Substantial credit risk. Default is a real possibility.

Very high levels of credit risk. Default of some kind appears probable.

Near default. A default or default-like process has begun, or the issuer is in standstill, or for a closed funding vehicle, payment capacity is irrevocably impaired. Conditions that are indicative of a ‘C’ category rating for an issuer include:

the issuer has entered into a grace or cure period following non-payment of a material financial obligation;

the issuer has entered into a temporary negotiated waiver or standstill agreement following a payment default on a material financial obligation;

the formal announcement by the issuer or their agent of a distressed debt exchange;

a closed financing vehicle where payment capacity is irrevocably impaired such that it is not expected to pay interest and/or principal in full during the life of the transaction, but where no payment default is imminent.

A-7

Restricted default. ‘RD’ ratings indicate an issuer that in Fitch’s opinion has experienced:

an uncured payment default on a bond, loan or other material financial obligation, but

has not entered into bankruptcy filings, administration, receivership, liquidation, or other formal winding-up procedure, and

has not otherwise ceased operating.

This would include:

the selective payment default on a specific class or currency of debt;

ii.

the uncured expiry of any applicable grace period, cure period or default forbearance period following a payment default on a bank loan, capital markets security or other material financial obligation;

iii.

the extension of multiple waivers or forbearance periods upon a payment default on one or more material financial obligations, either in series or in parallel; ordinary execution of a distressed debt exchange on one or more material financial obligations.

Default. ‘D’ ratings indicate an issuer that in Fitch’s opinion has entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure or that has otherwise ceased business.

Default ratings are not assigned prospectively to entities or their obligations; within this context, non-payment on an instrument that contains a deferral feature or grace period will generally not be considered a default until after the expiration of the deferral or grace period, unless a default is otherwise driven by bankruptcy or other similar circumstance, or by a distressed debt exchange.

In all cases, the assignment of a default rating reflects the agency’s opinion as to the most appropriate rating category consistent with the rest of its universe of ratings and may differ from the definition of default under the terms of an issuer’s financial obligations or local commercial practice.

Short-Term Credit Ratings

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations and up to 36 months for obligations in U.S. public finance markets.

Highest short-term credit quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

Good short-term credit quality. Good intrinsic capacity for timely payment of financial commitments.

Fair short-term credit quality. The intrinsic capacity for timely payment of financial commitments is adequate.

A-8

Speculative short-term credit quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near-term adverse changes in financial and economic conditions.

High short-term default risk. Default is a real possibility.

Restricted Default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.

Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Notes to Long-term and Short-term ratings:

“+” or “-” may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the ‘AAA’ Long-term rating category, to categories below ‘CCC, or to Short-term ratings other than ‘FT.

‘NR’ indicates that Fitch Ratings does not rate the issuer or issue in question.

‘Withdrawn’: A rating is withdrawn when Fitch Ratings deems the amount of information available to be inadequate for rating purposes, or when an obligation matures, is called, or refinanced.

Rating Watch: Ratings are placed on Rating Watch to notify investors that there is a reasonable probability of a rating change and the likely direction of such change. These are designated as “Positive”, indicating a potential upgrade, “Negative”, for a potential downgrade, or “Evolving”, if ratings may be raised, lowered or maintained. Rating Watch is typically resolved over a relatively short period.

A Rating Outlook indicates the direction a rating is likely to move over a one to two year period. Outlooks may be positive, stable, or negative. A positive or negative Rating Outlook does not imply a rating change is inevitable. Similarly, ratings for which outlooks are ‘stable’ could be downgraded before an outlook moves to positive or negative if circumstances warrant such an action. Occasionally, Fitch Ratings may be unable to identify the fundamental trend. In these cases, the Rating Outlook may be described as evolving.

APPENDIX B

DERIVATIVE STRATEGIES AND RISKS

Set forth below is additional information regarding the various techniques involving the use of derivatives.

FINANCIAL FUTURES

A financial future is an agreement between two parties to buy and sell a security for a set price on a future date. They have been designed by boards of trade which have been designated “contracts markets” by the Commodity Futures Trading Commission (“CFTC”).

The purchase of financial futures is for the purpose of hedging the Fund’s existing or anticipated holdings of long-term debt securities. For example, if the Fund desires to increase its exposure to long-term bonds and has identified long-term bonds it wishes to purchase at a future time, but expects market interest rates to decline (thereby causing the value of those bonds to increase), it might purchase financial futures. If interest rates did decrease, the value of those to-be-purchased long-term bonds would increase, but the value of the Fund’s financial futures would be expected to increase at approximately the same rate, thereby helping maintain the Fund’s purchasing power. When the Fund purchases a financial future, it deposits in cash or securities an “initial margin”, typically equal to an amount between 1% and 5% of the contract amount. Thereafter, the Fund’s account is either credited or debited on a daily basis in correlation with the fluctuation in price of the underlying future or other requirements imposed by the exchange in order to maintain an orderly market. The Fund must make additional payments to cover debits to its account and has the right to withdraw credits in excess of the liquidity, the Fund may close out its position at any time prior to expiration of the financial future by taking an opposite position. At closing a final determination of debits and credits is made, additional cash is paid by or to the Fund to settle the final determination and the Fund realizes a loss or gain depending on whether on a net basis it made or received such payments.

The sale of financial futures is for the purpose of hedging the Fund’s existing or anticipated holdings of long-term debt securities. For example, if the Fund owns long-term bonds and market interest rates were expected to increase (causing those bonds’ values to decline), it might sell financial futures. If interest rates did increase, the value of long-term bonds in the Fund’s portfolio would decline, but the value of the Fund’s financial futures would be expected to increase at approximately the same rate thereby keeping the net asset value of the Fund from declining as much as it otherwise would have.

Among the risks associated with the use of financial futures by the Fund as a hedging or anticipatory device, perhaps the most significant is the imperfect correlation between movements in the price of the financial futures and movements in the price of the debt securities which are the subject of the hedge.

Thus, if the price of the financial future moves less or more than the price of the securities which are the subject of the hedge, the hedge will not be fully effective. To compensate for this imperfect correlation, the Fund may enter into financial futures in a greater dollar amount than the dollar amount of the securities being hedged if the historical volatility of the prices of such securities has been greater than the historical volatility of the financial futures. Conversely, the Fund may enter into fewer financial futures if the historical volatility of the price of the securities being hedged is less than the historical volatility of the financial futures.

The market prices of financial futures may also be affected by factors other than interest rates. One of these factors is the possibility that rapid changes in the volume of closing transactions, whether due to volatile markets or movements by speculators, would temporarily distort the normal relationship between the markets in the financial future and the chosen debt securities. In these circumstances as well as in periods of rapid and large price movements. The Fund might find it difficult or impossible to close out a particular transaction.

B-1

OPTIONS ON FINANCIAL FUTURES

The Fund may also purchase put or call options on financial futures which are traded on a U.S. Exchange or board of trade and enter into closing transactions with respect to such options to terminate an existing position. The purchase of put options on financial futures is analogous to the purchase of put options by the Fund on its portfolio securities to hedge against the risk of rising interest rates. As with options on debt securities, the holder of an option may terminate his position by selling an option of the Fund. There is no guarantee that such closing transactions can be effected.

INDEX CONTRACTS

INDEX FUTURES

A tax-exempt bond index which assigns relative values to the tax-exempt bonds included in the index is traded on the Chicago Board of Trade. The index fluctuates with changes in the market values of all tax-exempt bonds included rather than a single bond. An index future is a bilateral agreement pursuant to which two parties agree to take or make delivery of an amount of cash-rather than any security-equal to a specified dollar amount times the difference between the index value at the close of the last trading day of the contract and the price at which the index future was originally written. Thus, an index future is similar to traditional financial futures except that settlement is made in cash.

INDEX OPTIONS

The Fund may also purchase put or call options on U.S. government or tax-exempt bond index futures and enter into closing transactions with respect to such options to terminate an existing position. Options on index futures are similar to options on debt instruments except that an option on an index future gives the purchaser the right, in return for the premium paid, to assume a position in an index contract rather than an underlying security at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance of the writer’s futures margin account which represents the amount by which the market price of the index futures contract, at exercise, is less than the exercise price of the option on the index future.

Bond index futures and options transactions would be subject to risks similar to transactions in financial futures and options thereon as described above.

SWAP AGREEMENTS

Swap agreements are two-party contracts entered into primarily by institutional investors, typically for periods ranging from a few weeks to several years. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or swapped between the parties are calculated with respect to a notional amount (the amount or value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) of a particular security, or in a basket of securities representing a particular index. Swap agreements may include, by way of example, (i) interest rate swaps, in which one party exchanges a commitment to pay a floating, shorter-term interest rate (typically by reference to the rate of a specific security or index) for the other party’s commitment to pay a fixed, longer-term interest rate (either as specifically agreed, or by reference to a specified security or index); (ii) interest rate caps, in which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate or cap; (iii) interest rate floors, in which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified level or floor; (iv) interest rate collars, in which a party sells a cap and purchases a floor, or vice versa, in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels or collar amounts; (v) total return swaps, in which one party commits to pay the total return of an underlying security or asset in return for receiving from the other party a

B-2

specified return or the return of another instrument (typically a floating short-term interest rate), and (vi) credit default swap, in which the buyer pays a periodic fee in return for a contingent payment by the seller upon a credit event (such as a default) happening with respect to a specified instrument, typically in an amount equivalent to the loss incurred on a specific investment in that security due to the credit event.

A Fund may enter into such swap agreements for any purpose consistent with the Fund’s investment objective, such as for the purpose of attempting to obtain, enhance, or preserve a particular desired return or spread at a lower cost to the Fund than if the Fund had invested directly in an instrument that yielded that desired return or spread. The Fund also may enter into swaps in order to protect against an increase in the price of securities that the Fund anticipates purchasing at a later date.

Whether the Fund’s use of swap agreements will be successful in furthering its investment objective will depend, in part, on the ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments and the changes in the future values, indices, or rates covered by the swap agreement. Swap agreements may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The Fund will enter swap agreements only with counterparties that the Adviser reasonably believes are capable of performing under the swap agreements. If there is a default by the other party to such a transaction, the Fund will have to rely on its contractual remedies (which may be limited by bankruptcy, insolvency or similar laws) pursuant to the agreements related to the transaction. Certain requirements imposed on the Fund by the Code, as amended, may limit the Fund’s ability to use swap agreements. The swap market is largely unregulated.

No indemnification shall be provided hereunder to a Covered Person:

(a) against any liability to the Trust or its Shareholders by reason of a final adjudication by the court or other body before which the proceeding was brought that he engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office;

(b) with respect to any matter as to which he shall have been finally adjudicated not to have acted in good faith in the reasonable belief that his action was in the best interests of the Trust; or

(c) in the event of a settlement or other disposition not involving a final adjudication (as provided in paragraph (a) or (b)) and resulting in a payment by a Covered Person, unless there has been either a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office by the court or other

body approving the settlement or other disposition or a reasonable determination, based on a review of readily available facts (as opposed to a full trial-type inquiry), that he did not engage in such conduct:

(i) by a vote of a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter); or

(ii) by written opinion of independent legal counsel.

The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be such a Covered Person and shall inure to the benefit of the heirs, executors and administrators of such a person. Nothing contained herein shall affect any rights to indemnification to which Trust personnel other than Covered Persons may be entitled by contract or otherwise under law.

Expenses of preparation and presentation of a defense to any claim, action, suit or proceeding subject to a claim for indemnification under this Section 4 shall be advanced by the Trust prior to final disposition thereof upon receipt of an undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that he is not entitled to indemnification under this Section 4, provided that either:

(a) such undertaking is secured by a surety bond or some other appropriate security or the Trust shall be insured against losses arising out of any such advances; or

(b) a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter) or independent legal counsel in a written opinion shall determine, based upon a review of the readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the recipient ultimately will be found entitled to indemnification.

As used in this Section 4, a “Disinterested Trustee” is one (x) who is not an Interested Person of the Trust (including anyone, as such Disinterested Trustee, who has been exempted from being an Interested Person by any rule, regulation or order of the Commission), and (y) against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending.

As used in this Section 4, the words “claim,” “action,” “suit” or “proceeding” shall apply to all claims, actions, suits, proceedings (civil, criminal, administrative or other, including appeals), actual or threatened; and the words “liability” and “expenses” shall include without limitation, attorneys’ fees, costs, judgments, amounts paid in settlement, fines, penalties and other liabilities.

The trustees and officers of the Registrant are covered by Mutual Fund Professional Liability policies in the aggregate amount of $70,000,000 against liability and expenses of claims of wrongful acts arising out of their position with the Registrant, except for matters which involve willful acts, bad faith, gross negligence and willful disregard of duty (i.e., where the insured did not act in good faith for a purpose he or she reasonably believed to be in the best interest of Registrant or where he or she had reasonable cause to believe this conduct was unlawful). The policy has a $1,000,000 deductible for operational failures and $1,000,000 deductible for all other claims.

Section 8 of the Underwriting Agreement to be filed as Exhibit h.1 to this Registration Statement provides for each of the parties thereto, including the Registrant and the Underwriters, to indemnify the others, their trustees, directors, certain of their officers, trustees, directors and persons who control them against certain liabilities in connection with the offering described herein, including liabilities under the federal securities laws.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding (is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will,

unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
