Delivery of Shareholder Documents. The Securities and Exchange Commission (the "SEC") permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called "householding" and it helps eliminate duplicate mailings to shareholders.

Eaton Vance, or your financial adviser, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial adviser, otherwise.

If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-262-1122, or contact your financial adviser.

Your instructions that householding not apply to delivery of your Eaton Vance documents will be effective within 30 days of receipt by Eaton Vance or your financial adviser.

Portfolio Holdings. Each Eaton Vance Fund and its underlying Portfolio (if applicable) will file a schedule of its portfolio holdings on Form N-Q with the SEC for the first and third quarters of each fiscal year. The Form N-Q will be available on the Eaton Vance website www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC's website at www.sec.gov.

Eaton Vance Insured Municipal Bond Funds as of March 31, 2008

INVESTMENT UPDATE

The investment objective of each Eaton Vance Insured Municipal Bond Fund (the “Funds”), closed-end funds traded on the American Stock Exchange, is to provide current income exempt from regular federal income tax, federal alternative minimum tax and, in state specific funds, state personal income taxes, as applicable. The Funds invest primarily in high-grade municipal securities that are insured as to the timely payment of principal and interest.

Economic and Market Conditions

Economic growth in the first quarter of 2008 measured 0.6%, according to preliminary Commerce Department data reported in April 2008, following the 0.6% growth rate achieved in the fourth quarter 2007. The housing sector continued to struggle in the first quarter due to market concerns related to subprime mortgages. Although the weaker dollar was having a beneficial effect on export-related industries, tourism, and U.S.- based multinational companies, consumers started to curtail spending, as food and energy costs continued to climb, according to Commerce Department data, and consumer confidence levels fell to 25-year lows, according to University of Michigan data.

On March 16, 2008, the Federal Reserve (the “Fed”) took extraordinary actions to support orderly market functioning after it learned that Bear Stearns faced a liquidity crisis which could have triggered a wider market crisis. In addition to approving a financing arrangement to support JPMorgan Chase’s acquisition of Bear Stearns, the Fed created a new lending facility that expanded the potential collateral it would accept from member banks and extended the new lending facility to securities firms. The Fed also lowered the Discount Rate, the rate at which it will lend to these firms, to 3.25% from 3.50%. Two days later, on March 18, 2008, at a regularly scheduled meeting of the Federal Open Market Committee, the Fed lowered the Federal Funds Rate by 75 basis points to 2.25% from 3.00% and further lowered the Discount Rate to 2.50%. The Federal Funds Rate has been lowered by a total of 300 basis points (3.00%) since September 18, 2007, from 5.25%, and the Discount Rate has been lowered by a total of 375 basis points (3.75%) since August 17, 2007, from 6.25%. Management believes that all of these actions were aimed at providing market liquidity during this period of extreme uncertainty and tight credit conditions that first surfaced in August 2007.

Management Discussion

The Funds invest primarily in bonds with stated maturities of 10 years or longer at the time of investment, as longer-maturity bonds historically have provided greater tax-exempt income for investors than shorter-maturity bonds.

The Funds underperformed their benchmark, the Lehman Brothers Municipal Bond Index – a broad-based, unmanaged index of municipal bonds – for the six months ended March 31, 2008.(1) Management believes that much of the underperformance can be attributed to the broader-based credit crisis that has shaken the fixed-income markets since August 2007, which led investors to move their capital into the Treasury market, particularly in shorter-maturity bonds. This move was originally driven by uncertainty surrounding financial companies’ exposure to mortgage-backed collateralized debt obligations (CDOs). More recently, the municipal bond market has been impacted by the downgrade of major municipal bond insurers due to their exposure to mortgage-related CDO debt. As a result of an active management style that focuses on income and longer call protection, the Funds generally hold longer-duration bonds. Although the municipal bond market stabilized and fund performance improved during March 2008, management believes that investors’ flight – from September 2007 through February 2008 – to shorter-maturity uninsured bonds from longer-maturity insured bonds resulted in the Funds’ relative underperformance for the period.

The ratio of yields on current coupon AAA-rated insured bonds to the yield on 30-year Treasury bonds was 116% as of March 31, 2008, with many individual bonds trading higher than 116% .(2) Management believes that this was the result of dislocation in the fixed-income marketplace caused by fears of subprime contagion, insurance companies’ mark-to-market risks and the decentralized nature of the municipal marketplace. Historically, this is a rare occurrence in the municipal bond market and is generally considered a signal that municipal bonds are significantly undervalued compared to Treasuries.

With this backdrop, management continues to manage all of its municipal funds with the same relative value approach that it has traditionally employed – maintaining a long-term perspective when markets exhibit extreme short-term volatility. We believe this approach has provided excellent long-term benefits to our investors over time.

(1) It is not possible to invest directly in an Index. The Index’s total return does not reflect expenses that would have been incurred if an investor individually purchased or sold the securities represented in the Index.

Private insurance does not decrease the risk of loss associated with Fund shares.

Past performance is no guarantee of future results.

The views expressed throughout this report are those of the portfolio managers and are current only through the end of the period of the report as stated on the cover. These views are subject to change at any time based upon market or other conditions, and the investment adviser disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a fund are based on many factors, may not be relied on as an indication of trading intent on behalf of any Eaton Vance fund. Portfolio information provided in the report may not be representative of the Funds’ current or future investments and may change due to active management.

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

As has been widely reported since mid-February 2008, the normal functioning of the auction market in the U.S. for certain types of “auction rate securities” has been disrupted by an imbalance between buy and sell orders. Consistent with patterns in the broader market for auction rate securities, the Funds have, since-mid February, experienced unsuccessful Auction Preferred Share (APS) auctions. In the event of an unsuccessful auction, the affected APS shares remain outstanding, and the dividend rate reverts to the specified maximum payable rate.

On April 23, 2008, after the end of the reporting period, management announced that it had secured new financing that the Funds intend to use to redeem a portion of their outstanding APS, subject to satisfying the notice and other requirements that apply to APS redemptions. Eaton Vance Insured Municipal Bond Fund, Eaton Vance Insured California Municipal Bond Fund and Eaton Vance Insured New York Municipal Bond Fund plan to redeem approximately 65%, 55% and 63%, respectively, of their outstanding APS by May 16, 2008. Management is working diligently to provide liquidity solutions that will enable the Funds to redeem their remaining outstanding APS. It is not certain when, or if, the Funds’ remaining APS will be redeemed.

* The leverage amount is Auction Preferred Shares at liquidation value as a percentage of the Fund’s net assets applicable to common shares plus Auction Preferred Shares. The Fund uses leverage through the issuance of preferred shares. Use of financial leverage creates an opportunity for increased income but, at the same time, creates special risks (including the likelihood of greater volatility of net asset value and market price of common shares).

(1) Returns are historical and are calculated by determining the percentage change in share price or net asset value with all distributions reinvested. The Fund’s performance at market share price will differ from its results at NAV. Although share price performance generally reflects investment results over time, during shorter periods, returns at share price can also be affected by factors such as changing perceptions about the Fund, market conditions, fluctuations in supply and demand for the Fund’s shares, or changes in Fund distributions. Performance results reflect the effect of leverage resulting from the Fund’s issuance of Auction Preferred Shares.

(2) The Fund’s market yield is calculated by dividing the last dividend paid per common share of the semi-annual period by the share price at the end of the semi-annual period and annualizing the result.

(3) Taxable-equivalent figure assumes a maximum 35.00% federal income tax rate. A lower tax rate would result in a lower tax-equivalent figure.

(4) It is not possible to invest directly in an Index. The Index’s total return does not reflect the expenses that would have been incurred if an investor individually purchased or sold the securities represented in the Index. Index performance is available as of month-end only.

(5) The Lipper Averages are the average total returns, at net asset value, of the funds that are in the same Lipper Classification as the Fund. It is not possible to invest in a Lipper Classification. Lipper Classifications may include insured and uninsured funds, as well as leveraged and unleveraged funds. The Lipper Insured Municipal Debt Funds (Leveraged) Classification (closed-end) contained 23, 23, 23 and 20 funds for the 6-month, 1-year, 5-year and Life-of-Fund periods, respectively. Lipper Averages are available as of month-end only.

(6) Rating Distribution is determined by dividing the total market value of the issues by the total investments of the Fund.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value or share price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance is for the stated time period only; due to market volatility, the Fund’s current performance may be lower or higher than the quoted return.

The aggregate percentage insured by an individual financial institution ranged from 3.3% to 25.7% of total investments.

1 Significant Accounting Policies

Eaton Vance Insured Municipal Bond Fund (Insured Municipal Fund), Eaton Vance Insured California Municipal Bond Fund (Insured California Fund) and Eaton Vance Insured New York Municipal Bond Fund (Insured New York Fund), (each individually referred to as the Fund, and collectively, the Funds), are Massachusetts business trusts registered under the Investment Company Act of 1940, as amended (the 1940 Act), as non-diversified, closed-end management investment companies. Each Fund seeks to provide current income exempt from regular federal income tax, including alternative minimum tax, and, in state specific funds, taxes in its specified state.

The following is a summary of significant accounting policies of the Funds. The policies are in conformity with accounting principles generally accepted in the United States of America.

A Investment Valuation — Municipal bonds and taxable obligations, if any, are generally valued on the basis of valuations furnished by a pricing service. Financial futures contracts and options on financial futures contracts listed on commodity exchanges are valued at closing settlement prices. Interest rate swaps are generally valued on the basis of valuations furnished by a pricing service. Short-term obligations, maturing in sixty days or less, are valued at amortized cost, which approximates market value. Investments for which valuations or market quotations are not readily available, and investments for which the price of a security is not believed to represent its fair market value, are valued at fair value using methods determined in good faith by or at the direction of the Trustees.

B Investment Transactions and Related Income — Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost. Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount.

C Federal Taxes — Each Fund's policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year substantially all of its taxable, if any, and tax-exempt net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary. Each Fund intends to satisfy conditions which will enable it to designate distributions from the interest income generated by its investments in municipal obligations, which are exempt from regular federal income tax when received by each Fund, as exempt-interest dividends.

At September 30, 2007, the following Funds, for federal income tax purposes, had capital loss carryforwards which will reduce each Fund's taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus will reduce the amount of distributions to shareholders, which would otherwise be necessary to relieve the Funds of any liability for federal income or excise tax. The amounts and expiration dates of the capital loss carryforwards are as follows:

Fund				Amount				Expiration Date
Insured New York				$	170,661			September 30, 2013

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48 (FIN 48), "Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109". FIN 48 clarifies the accounting for uncertainty in income taxes recognized in accordance with FASB Statement No. 109, "Accounting for Income Taxes". This interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 is effective on the last business day of the first required financial reporting period for fiscal years beginning after December 15, 2006. Management has concluded that as of March 31, 2008, there are no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. Each of the Funds' federal tax returns filed in the 3-year period ended September 30, 2007 remains subject to examination by the Internal Revenue Service.

D Expense Reduction — State Street Bank and Trust Company (SSBT) serves as custodian of the Funds. Pursuant to the respective custodian agreements, SSBT receives a fee reduced by credits, which are determined based on the average daily cash balance each Fund maintains with SSBT. All credit balances, if any, used to reduce each Fund's custodian fees are reported as a reduction of expenses in the Statements of Operations.

Eaton Vance Insured Municipal Bond Funds as of March 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D

E Legal Fees — Legal fees and other related expenses incurred as part of negotiations of the terms and requirement of capital infusions, or that are expected to result in the restructuring of, or a plan of reorganization for, an investment are recorded as realized losses. Ongoing expenditures to protect or enhance an investment are treated as operating expenses.

F Use of Estimates — The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates.

G Indemnifications — Under each Fund's organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to each Fund, and shareholders are indemnified against personal liability for the obligations of each Fund. Additionally, in the normal course of business, each Fund enters into agreements with service providers that may contain indemnification clauses. Each Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against each Fund that have not yet occurred.

H Financial Futures Contracts — The Funds may enter into financial futures contracts. The Funds' investment in financial futures contracts is designed for hedging against changes in interest rates or as a substitute for the purchase of securities. Upon entering into a financial futures contract, a Fund is required to deposit with the broker, either in cash or securities an amount equal to a certain percentage of the purchase price (initial margin). Subsequent payments, known as variation margin, are made or received by the Fund each business day, depending on the daily fluctuations in the value of the underlying security, and are recorded as unrealized gains or losses by the Fund. Gains (losses) are realized upon the expiration or closing of the financial futures contracts. Should market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. In entering such contracts, the Fund bears the risk if the counterparties do not perform under the contracts' terms.

I Interest Rate Swaps — A Fund may enter into interest rate swap agreements to enhance return, to hedge against fluctuations in securities prices or interest rates, or as substitution for the purchase or sale of securities. Pursuant to these agreements, a Fund makes periodic payments at a fixed interest rate and, in exchange, receives payments based on the interest rate of a benchmark industry index. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains or losses. The value of the swap is determined by changes in the relationship between two rates of interest. A Fund is exposed to credit loss in the event of non-performance by the swap counterparty. Risk may also arise from movements in interest rates.

J When-Issued Securities and Delayed Delivery Transactions — The Funds may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. At the time the transaction is negotiated, the price of the security that will be delivered is fixed. The Funds maintain security positions for these commitments such that sufficient liquid assets will be available to make payments upon settlement. Securities purchased on a delayed delivery or when-issued basis are marked-to-market daily and begin earning interest on settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

K Interim Financial Statements — The interim financial statements relating to March 31, 2008 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Funds' management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2 Auction Preferred Shares

Each Fund issued Auction Preferred Shares (APS) on October 29, 2002 in a public offering. The underwriting discounts and other offering costs incurred in connection with the offering were recorded as a reduction of the paid-in capital of the common shares of each respective Fund. Dividends on the APS, which accrue daily, are cumulative at rates which are reset every seven days by an auction, unless a special dividend period has been set.

Eaton Vance Insured Municipal Bond Funds as of March 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D

If the APS auctions do not successfully clear, the dividend payment rate over the next period for the APS holders is set at a specified maximum applicable rate until such time as the APS auctions are successful. The maximum applicable rate on the APS is 110% (150% for taxable distributions) of the greater of the 1) "AA" Financial Composite Commercial Paper Rate or 2) Taxable Equivalent of the Short-Term Municipal Obligation Rate on the date of the auction. Series of APS are identical in all respects except for the reset dates of the dividend rates.

The number of APS issued and outstanding as of March 31, 2008 are as follows:

Fund	APS Issued and Outstanding
Insured Municipal
Series A		4,740
Series B		4,740
Series C		4,740
Series D		4,740
Series E		4,740
Insured California
Series A		3,900
Series B		3,900
Insured New York
Series A		2,850
Series B		2,850

The APS are redeemable at the option of each Fund at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, on any dividend payment date. The APS are also subject to mandatory redemption at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, if a Fund is in default for an extended period on its asset maintenance requirements with respect to the APS. If the dividends on the APS remain unpaid in an amount equal to two full years' dividends, the holders of the APS as a class have the right to elect a majority of the Board of Trustees. In general, the holders of the APS and the common shares have equal voting rights of one vote per share, except that the holders of the APS, as a separate class, have the right to elect at least two members of the Board of Trustees. The APS have a liquidation preference of $25,000 per share, plus accumulated and unpaid dividends. Each Fund is required to maintain certain asset coverage with respect to the APS as defined in the Funds' By-Laws and the 1940 Act. Each Fund pays an annual fee equivalent to 0.25% of the liquidation value of the APS for the remarketing efforts associated with the APS auctions.

3 Distributions to Shareholders

Each Fund intends to make monthly distributions of net investment income to common shareholders, after payment of any dividends on any outstanding APS. In addition, at least annually, the Funds intend to distribute all or substantially all of their net realized capital gains (reduced by available capital loss carryforwards from prior years, if any). Distributions to common shareholders are recorded on the ex-dividend date. Distributions to preferred shareholders are recorded daily and are payable at the end of each dividend period. The dividend rates for APS at March 31, 2008, and the amount of dividends paid (including capital gains, if any) to APS shareholders, average APS dividend rates (annualized), and dividend rate ranges for the six months then ended were as follows:

Fund	APS Dividend Rates at March 31, 2008			Dividends Paid to APS Shareholders		Average APS Dividend Rates			Dividends Rate Ranges
Insured Municipal
Series A		3.02	%	$	2,257,127		3.81	%	2.40% - 4.77%
Series B		3.23	%	$	2,192,716		3.70	%	2.25% - 5.50%
Series C		3.23	%	$	2,180,928		3.68	%	2.00% - 6.45%
Series D		3.23	%	$	2,183,023		3.68	%	1.95% - 4.51%
Series E		3.23	%	$	2,294,404		3.87	%	2.75% - 5.50%
Insured California
Series A		3.23	%	$	2,009,921		4.12	%	2.14% - 6.85%
Series B		3.23	%	$	1,955,157		4.01	%	2.10% - 7.05%
Insured New York
Series A		3.02	%	$	1,231,177		3.46	%	1.80% - 4.78%
Series B		3.23	%	$	1,240,660		3.48	%	2.40% - 4.51%

Beginning February 13, 2008 and consistent with the patterns in the broader market for auction-rate securities, the Funds' APS auctions were unsuccessful in clearing due to an imbalance of sell orders over bids to buy the APS. As a result, the dividend rates of the APS were reset to the maximum applicable rate. The table above reflects such maximum dividend rate of each series as of March 31, 2008.

The Funds distinguish between distributions on a tax basis and a financial reporting basis. Accounting principles generally accepted in the United States of America require that only distributions in excess of tax

Eaton Vance Insured Municipal Bond Funds as of March 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D

basis earnings and profits be reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in capital.

4 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Eaton Vance Management (EVM) as compensation for investment advisory services rendered to each Fund. The fee is computed at an annual rate of 0.65% of each Fund's average weekly gross assets and is payable monthly. EVM also serves as the administrator of each Fund, but receives no compensation.

In addition, EVM has contractually agreed to reimburse the Funds for fees and other expenses at an annual rate of 0.32% of average weekly gross assets of each Fund during the first five full years of its operations, 0.24% of a Fund's average weekly gross assets in year six, 0.16% in year seven and 0.08% in year eight. The Funds concluded their first five full years of operations on August 30, 2007. For the six months ended March 31, 2008, the investment adviser fee and expenses contractually reduced by EVM were as follows:

Fund	Investment Adviser Fee		Expenses Reduced by EVM
Insured Municipal	$	4,944,066	$	1,825,501
Insured California		1,634,844		603,635
Insured New York		1,191,915		440,092

Except for Trustees of the Funds who are not members of EVM's organization, officers and Trustees receive remuneration for their services to the Funds out of the investment adviser fee. Trustees of the Funds who are not affiliated with the investment adviser may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended March 31, 2008, no significant amounts have been deferred. Certain officers and Trustees of the Funds are officers of EVM.

5 Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, for the six months ended March 31, 2008 were as follows:

Fund	Purchases		Sales
Insured Municipal	$	424,019,467	$	435,842,658
Insured California		61,482,117		78,225,459
Insured New York		87,674,929		90,150,591

6 Common Shares of Beneficial Interest

Common shares issued pursuant to the Funds' dividend reinvestment plan for the six months ended March 31, 2008 and the year ended September 30, 2007 were as follows:

Fund	Six Months Ended March 31, 2008 (Unaudited)		Year Ended September 30, 2007
Insured Municipal		86,874		91,779
Insured California		11,264		12,088
Insured New York		18,989		16,071

7 Federal Income Tax Basis of Investments

The cost and unrealized appreciation (depreciation) of investments of each Fund at March 31, 2008, as determined on a federal income tax basis, were as follows:

Insured Municipal Fund
Aggregate Cost	$	1,512,142,816
Gross unrealized appreciation	$	7,710,188
Gross unrealized depreciation		(72,847,691	)
Net unrealized depreciation	$	(65,137,503	)
Insured California Fund
Aggregate Cost	$	490,121,117
Gross unrealized appreciation	$	3,108,053
Gross unrealized depreciation		(22,807,665	)
Net unrealized depreciation	$	(19,699,612	)
Insured New York Fund
Aggregate Cost	$	358,507,805
Gross unrealized appreciation	$	3,072,795
Gross unrealized depreciation		(12,010,568	)
Net unrealized depreciation	$	(8,937,773	)

8 Overdraft Advances

Pursuant to the respective custodian agreements, SSBT may, in its discretion, advance funds to the Funds to make properly authorized payments. When such payments result in an overdraft, the Funds are obligated to repay SSBT at the current rate of interest charged by SSBT for secured loans (currently, a rate above the

Eaton Vance Insured Municipal Bond Funds as of March 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D

Federal Funds rate). This obligation is payable on demand to SSBT. SSBT has a lien on a Fund's assets to the extent of any overdraft. At March 31, 2008, the Insured New York Fund had a payment due to SSBT pursuant to the foregoing arrangement of $617,099.

9 Financial Instruments

The Funds may trade in financial instruments with off-balance sheet risk in the normal course of their investing activities to assist in managing exposure to various market risks. These financial instruments may include financial futures contracts and interest rate swaps and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment a Fund has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered.

10 Recently Issued Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (FAS 157), "Fair Value Measurements". FAS 157 defines fair value, establishes a framework for measuring fair value in accordance with generally accepted accounting principles and expands disclosure about fair value measurements. FAS 157 is effective for fiscal years beginning after November 15, 2007. As of March 31, 2008, management does not believe the adoption of FAS 157 will impact the amounts reported in the financial statements; however, additional disclosures may be required about the inputs used to develop the measurements of fair value and the effect of certain of the measurements on changes in net assets for the period.

Eaton Vance Insured Municipal Bond Funds as of March 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161 (FAS 161), "Disclosures about Derivative Instruments and Hedging Activities". FAS 161 requires enhanced disclosures about an entity's derivative and hedging activities, including qualitative disclosures about the objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk related contingent features in derivative instruments. FAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008. Management is currently evaluating the impact the adoption of FAS 161 will have on the Funds' financial statement disclosures.

11 Subsequent Event

In April 2008, the Funds secured financing intended to partially redeem a proportionate amount of each series of the Funds' APS. The replacement financing is being provided through the creation of tender option bonds, whereby each Fund transfers highly rated bonds held in its portfolio to a special purpose trust that issues floater and residual certificates. The Funds will hold the residual certificates and use the proceeds from the sale of the floater certificates to replace a portion of the outstanding APS. The floaters have a liquidity backstop financing facility provided by a major financial institution. The Insured Municipal Fund, Insured California Fund and Insured New York Fund expect to redeem approximately 65%, 55% and 63%, respectively, of their outstanding APS at the next respective dividend payable date on or after May 12, 2008.

Eaton Vance Insured Municipal Bond Funds

DIVIDEND REINVESTMENT PLAN

Each Fund offers a dividend reinvestment plan (the Plan) pursuant to which shareholders may elect to have dividends and capital gains distributions automatically reinvested in common shares (the Shares) of the same Fund. You may elect to participate in the Plan by completing the Dividend Reinvestment Plan Application Form. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you by PFPC Inc. as dividend paying agent. On the distribution payment date, if the net asset value per Share is equal to or less than the market price per Share plus estimated brokerage commissions, then new Shares will be issued. The number of Shares shall be determined by the greater of the net asset value per Share or 95% of the market price. Otherwise, Shares generally will be purchased on the open market by the Plan Agent. Distributions subject to income tax (if any) are taxable whether or not shares are reinvested.

If your shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the Plan on your behalf. If the nominee does not offer the Plan, you will need to request that your shares be re-registered in your name with each Fund's transfer agent, PFPC Inc., or you will not be able to participate.

The Plan Agent's service fee for handling distributions will be paid by each Fund. Each participant will be charged their pro rata share of brokerage commissions on all open-market purchases.

Plan participants may withdraw from the Plan at any time by writing to the Plan Agent at the address noted on the following page. If you withdraw, you will receive shares in your name for all Shares credited to your account under the Plan. If a participant elects by written notice to the Plan Agent to have the Plan Agent sell part or all of his or her Shares and remit the proceeds, the Plan Agent is authorized to deduct a $5.00 fee plus brokerage commissions from the proceeds.

If you wish to participate in the Plan and your shares are held in your own name, you may complete the form on the following page and deliver it to the Plan Agent.

Any inquiries regarding the Plan can be directed to the Plan Agent, PFPC Inc., at 1-866-439-6787.

BOARD OF TRUSTEES' ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended (the "1940 Act"), provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuance is approved at least annually by the fund's board of trustees, including by a vote of a majority of the trustees who are not "interested persons" of the fund ("Independent Trustees"), cast in person at a meeting called for the purpose of considering such approval.

At a meeting of the Boards of Trustees (each a "Board") of the Eaton Vance group of mutual funds (the "Eaton Vance Funds") held on April 23, 2007, the Board, including a majority of the Independent Trustees, voted to approve continuation of existing advisory and sub-advisory agreements for the Eaton Vance Funds for an additional one-year period. In voting its approval, the Board relied upon the affirmative recommendation of the Special Committee of the Board, which is a committee comprised exclusively of Independent Trustees. Prior to making its recommendation, the Special Committee reviewed information furnished for a series of meetings of the Special Committee held in February, March and April 2007. Such information included, among other things, the following:

Information about Fees, Performance and Expenses

• An independent report comparing the advisory and related fees paid by each fund with fees paid by comparable funds;

• An independent report comparing each fund's total expense ratio and its components to comparable funds;

• An independent report comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;

• Data regarding investment performance in comparison to relevant peer groups of funds and appropriate indices;

• Comparative information concerning fees charged by each adviser for managing other mutual funds and institutional accounts using investment strategies and techniques similar to those used in managing the fund;

• Profitability analyses for each adviser with respect to each fund;

Information about Portfolio Management

• Descriptions of the investment management services provided to each fund, including the investment strategies and processes employed;

• Information concerning the allocation of brokerage and the benefits received by each adviser as a result of brokerage allocation, including information concerning the acquisition of research through "soft dollar" benefits received in connection with the funds' brokerage, and the implementation of a soft dollar reimbursement program established with respect to the funds;

• Data relating to portfolio turnover rates of each fund;

• The procedures and processes used to determine the fair value of fund assets and actions taken to monitor and test the effectiveness of such procedures and processes;

Information about each Adviser

• Reports detailing the financial results and condition of each adviser;

• Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;

• Copies of the Codes of Ethics of each adviser and its affiliates, together with information relating to compliance with and the administration of such codes;

• Copies of or descriptions of each adviser's proxy voting policies and procedures;

• Information concerning the resources devoted to compliance efforts undertaken by each adviser and its affiliates on behalf of the funds (including descriptions of various compliance programs) and their record of compliance with investment policies and restrictions, including policies with respect to market-timing, late trading and selective portfolio disclosure, and with policies on personal securities transactions;

• Descriptions of the business continuity and disaster recovery plans of each adviser and its affiliates;

Other Relevant Information

• Information concerning the nature, cost and character of the administrative and other non-investment management services provided by Eaton Vance Management and its affiliates;

• Information concerning management of the relationship with the custodian, subcustodians and fund accountants by each adviser or the funds' administrator; and

• The terms of each advisory agreement.

BOARD OF TRUSTEES' ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS CONT'D

In addition to the information identified above, the Special Committee considered information provided from time to time by each adviser throughout the year at meetings of the Board and its committees. Over the course of the twelve-month period ended April 30, 2007, the Board met ten times and the Special Committee, the Audit Committee and the Governance Committee, each of which is a Committee comprised solely of Independent Trustees, met twelve, fourteen and eight times, respectively. At such meetings, the Trustees received, among other things, presentations by the portfolio managers and other investment professionals of each adviser relating to the investment performance of each fund and the investment strategies used in pursuing the fund's investment objective.

For funds that invest through one or more underlying portfolios, the Board considered similar information about the portfolio(s) when considering the approval of advisory agreements. In addition, in cases where the fund's investment adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any sub-advisory agreement.

The Special Committee was assisted throughout the contract review process by Goodwin Procter LLP, legal counsel for the Independent Trustees. The members of the Special Committee relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each advisory and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each advisory and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Special Committee may have placed varying emphasis on particular factors in reaching conclusions with respect to each advisory and sub-advisory agreement.

Results of the Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Special Committee concluded that the continuance of the investment advisory agreements of the following funds:

• Eaton Vance Insured Municipal Bond Fund

• Eaton Vance Insured California Municipal Bond Fund

• Eaton Vance Insured New York Municipal Bond Fund

(the "Funds"), each with Eaton Vance Management (the "Adviser"), including their fee structures, is in the interests of shareholders and, therefore, the Special Committee recommended to the Board approval of each agreement. The Board accepted the recommendation of the Special Committee as well as the factors considered and conclusions reached by the Special Committee with respect to each agreement. Accordingly, the Board, including a majority of the Independent Trustees, voted to approve continuation of the advisory agreement for each Fund.

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory agreements of the Funds, the Board evaluated the nature, extent and quality of services provided to the Funds by the Adviser.

The Board considered the Adviser's management capabilities and investment process with respect to the types of investments held by each Fund, including the education, experience and number of its investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Funds. In particular, the Board evaluated, where relevant, the abilities and experience of such investment personnel in analyzing factors such as credit risk, tax efficiency, and special considerations relevant to investing in municipal bonds. Specifically, the Board considered the Adviser's 30-person municipal bond team, which includes six portfolio managers and nine credit specialists who provide services to the Funds. The Board also took into account the resources dedicated to portfolio management and other services, including the compensation paid to recruit and retain investment personnel, and the time and attention devoted to each Fund by senior management.

The Board reviewed the compliance programs of the Adviser and relevant affiliates thereof. Among other matters, the Board considered compliance and reporting matters relating to personal trading by investment personnel, selective disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also evaluated the responses of the Adviser and its affiliates to requests from regulatory authorities such as the Securities and Exchange Commission and the National Association of Securities Dealers.

The Board also considered shareholder and other administrative services provided or managed by Eaton Vance Management and its affiliates, including transfer agency and accounting services. The Board evaluated the benefits to shareholders of investing in a fund that is a part of a large family of funds.

After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by the Adviser, taken as a whole, are appropriate and consistent with the terms of the respective investment advisory agreements.

Fund Performance

The Board compared each Fund's investment performance to a relevant universe of similarly managed funds identified by an independent data provider and appropriate benchmark indices. The Board reviewed comparative performance data for the one-year and three-year periods ended September 30, 2006 for each Fund. On the basis of the foregoing and other relevant information, the Board concluded that the performance of each Fund is satisfactory.

Management Fees and Expenses

The Board reviewed contractual investment advisory fee rates, including any administrative fee rates, payable by each Fund (referred to collectively as "management fees"). As part of its review, the Board considered each Fund's management fee and total expense ratio for the year ended September 30, 2006, as compared to a group of similarly managed funds selected by an independent data provider. The Board considered the fact that the Adviser had waived fees and/or paid expenses for each of the Funds.

After reviewing the foregoing information, and in light of the nature, extent and quality of the services provided by the Adviser, the Board concluded with respect to each Fund that the management fees charged to the Fund for advisory and related services and the total expense ratio of the Fund are reasonable.

Profitability

The Board reviewed the level of profits realized by the Adviser and, if applicable, its affiliates in providing investment advisory and administrative services to each Fund and to all Eaton Vance Funds as a group. The Board considered the level of profits realized without regard to revenue sharing or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered other direct or indirect benefits received by the Adviser and its affiliates in connection with their relationship with the Funds.

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by the Adviser and its affiliates are reasonable.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the Adviser and its affiliates, on the one hand, and each Fund, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund increase. The Board acknowledged the difficulty in accurately measuring the benefits resulting from the economies of scale with respect to the management of any specific fund or group of funds. The Board also considered the fact that none of the Funds is continuously offered and concluded that, in light of the level of the Adviser's profits with respect to each Fund, the implementation of breakpoints in the advisory fee schedule is not appropriate. Based upon the foregoing, the Board concluded that the benefits from economies of scale are currently being shared equitably by the Adviser and its affiliates and each Fund.

Item 6. Schedule of Investments

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

The Board of Trustees of the Trust has adopted a proxy voting policy and procedure (the “Fund Policy”), pursuant to which the Trustees have delegated proxy voting responsibility to the Fund’s investment adviser and adopted the investment adviser’s proxy voting policies and procedures (the “Policies”) which are described below. The Trustees will review the Fund’s proxy voting records from time to time and will annually consider approving the Policies for the upcoming year. In the event that a conflict of interest arises between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund, the investment adviser will generally refrain from voting the proxies related to the companies giving rise to such conflict until it consults with the Board’s Special Committee except as contemplated under the Fund Policy. The Board’s Special Committee will instruct the investment adviser on the appropriate course of action.

The Policies are designed to promote accountability of a company’s management to its shareholders and to align the interests of management with those shareholders. An independent proxy voting service (“Agent”), currently Institutional Shareholder Services, Inc., has been retained to assist in the voting of proxies through the provision of vote analysis, implementation and recordkeeping and disclosure services. The investment adviser will generally vote proxies through the Agent. The Agent is required to vote all proxies and/or refer then back to the investment adviser pursuant to the Policies. It is

generally the policy of the investment adviser to vote in accordance with the recommendation of the Agent. The Agent shall refer to the investment adviser proxies relating to mergers and restructurings, and the disposition of assets, termination, liquidation and mergers contained in mutual fund proxies. The investment adviser will normally vote against anti-takeover measures and other proposals designed to limit the ability of shareholders to act on possible transactions, except in the case of closed-end management investment companies. The investment adviser generally supports management on social and environmental proposals. The investment adviser may abstain from voting from time to time where it determines that the costs associated with voting a proxy outweighs the benefits derived from exercising the right to vote or the economic effect on shareholders interests or the value of the portfolio holding is indeterminable or insignificant.

In addition, the investment adviser will monitor situations that may result in a conflict of interest between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund by maintaining a list of significant existing and prospective corporate clients. The investment adviser’s personnel responsible for reviewing and voting proxies on behalf of the Fund will report any proxy received or expected to be received from a company included on that list to the personal of the investment adviser identified in the Policies. If such personnel expects to instruct the Agent to vote such proxies in a manner inconsistent with the guidelines of the Policies or the recommendation of the Agent, the personnel will consult with members of senior management of the investment adviser to determine if a material conflict of interests exists. If it is determined that a material conflict does exist, the investment adviser will seek instruction on how to vote from the Special Committee.

Information on how the Fund voted proxies relating to portfolio securities during the most recent 12 month period ended June 30 is available (1) without charge, upon request, by calling 1-800-262-1122, and (2) on the Securities and Exchange Commission’s website at http://www.sec.gov.
