FUND REPORT For the year ended October 31, 2006 MARKET CONDITIONS Against the backdrop of strong economic growth, good employment data and inflationary pressures stemming from rising oil prices, the Federal Open Market Committee (the "Fed") continued its tightening campaign during the first eight months of the reporting period, raising the federal funds target rate six times to 5.25 percent at the end of June. In the months that followed, however, economic growth moderated as consumer spending and housing weakened while inflation concerns eased, prompting the Fed to keep its target rate unchanged for the remainder of the period. Short-term municipal bonds posted the lowest returns as Fed rate hikes pushed yields in this portion of the market higher. Representative yields on two-year AAA municipals increased from 3.10 percent to 3.50 percent during the period. In contrast, long-term municipal bonds earned the best returns, with yields on 30-year AAA-rated municipal bonds declining from 4.60 percent to 4.10 percent. Accordingly, the spread between long-term and short-term interest rates narrowed and the slope of the municipal yield curve flattened dramatically. Continued interest in the municipal market by institutional investors and non-traditional buyers such as hedge funds strengthened demand for municipal bonds. However, municipal bond issuance lagged last year's record pace by 12 percent in the first 10 months of 2006. The overall decline was due in great part to a slowdown of refunding activity to roughly one half of the previous year's rate. Issuers in California, Texas, Florida, New York and Illinois accounted for about 40 percent of 2006 year-to-date underwriting volume. Bond issues backed by insurance had close to a 50 percent market share. Strong demand and lower supply helped municipal bond performance keep pace with that of Treasuries. The municipal-to-Treasury yield ratio measures the relative attractiveness of the two sectors. A decline in this ratio indicates that while municipals outperformed Treasuries for the period measured, they also became richer (less attractive) on a relative basis. During the 12-month reporting period, the 30-year municipal-to-Treasury yield ratio declined from 92 to 87 percent. In comparison, this yield ratio reached a high of 102 percent in 2005. The State of California continued to lead the nation in municipal issuance, despite new volume declines of almost 20 percent. California's municipal market has benefited from the continued strengthening of its credit fundamentals and the near-term credit outlook for the state is stable. California's large and diverse economy continued to grow and employment gains were in line with the national average. On the fiscal front, a rebound in capital gain and stock option taxes contributed to higher revenues. In addition, Governor Schwarzenegger has made progress advancing a number of his municipal funding proposals. The state still faces challenges, however, with budget deficits, pension funding litigation and immigration issues among the most significant. PERFORMANCE ANALYSIS For the 12-month period ended October 31, 2006, the net asset value (NAV) of Morgan Stanley Insured California Municipal Securities (ICS) decreased from $15.17 to $15.15 per share. Based on this change plus reinvestment of tax-free dividends totaling $0.600 2 per share, a short-term capital gain distribution of $0.037 and a long-term capital gain distribution of $0.319 per share, the Trust's total NAV return was 7.00 percent. ICS's value on the New York Stock Exchange (NYSE) moved from $13.99 to $14.06 per share during the same period. Based on this change plus reinvestment of dividends and distributions, the Trust's total market return was 7.68 percent. ICS's NYSE market price was at a 7.19 percent discount to its NAV. During the fiscal period, the Trust purchased and retired 96,400 shares of common stock at a weighted average market discount of 7.81 percent. Past performance is no guarantee of future results. Monthly dividends for the fourth quarter of 2006, declared in September were unchanged at $0.05 per share. The dividend reflects the current level of the Trust's net investment income. ICS's level of undistributed net investment income was $0.107 per share on October 31, 2006, versus $0.110 per share 12 months earlier.(1) During the reporting period, the Trust's interest-rate posture continued to reflect the anticipation of higher rates. As a result, at the end of October the Trust's option-adjusted duration* was conservatively positioned at 7.3 years. To implement this strategy of reducing the portfolio's duration, a U.S. Treasury futures hedge was used. This positioning helped total returns as interest rates rose but tempered performance when rates declined. Purchases during the period favored bonds with maturities of 20 years or longer. The Trust benefited from this emphasis on the long end of the yield curve, as this segment of the market performed strongly. Another boost to performance came from issues that appreciated significantly when they were pre-refunded. Reflecting a commitment to diversification, the Trust's net assets of approximately $53 million were invested among 11 long-term sectors and 36 credits. As of the close of the period, the Trust's largest allocations were to the water and sewer, refunded, and general obligation sectors. The Trust's procedure for reinvesting all dividends and distributions on common shares is through purchases in the open market. This method helps support the market value of the Trust's shares. In addition, we would like to remind you that the Trustees have approved a procedure whereby the Trust may, when appropriate, purchase shares in the open market or in privately negotiated transactions at a price not above market value or net asset value, whichever is lower at the time of purchase. ---------------------------------------------------- PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE RESULTS, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE FIGURES SHOWN.

(1) Income earned by certain securities in the portfolio may be subject to the federal alternative minimum tax (AMT). * A measure of the sensitivity of a bond's price to changes in interest rates, expressed in years. Each year of duration represents an expected 1 percent change in the price of a bond for every 1 percent change in interest rates. The longer a bond's duration, the greater the effect of interest-rate movements on its price. Typically, trusts with shorter durations perform better in rising-interest-rate environments, while trusts with longer durations perform better when rates decline. 3 TOP FIVE SECTORS Water & Sewer 27.0% Refunded 14.3 General Obligation 11.2 Tax Allocation 8.7 Education 6.5 CREDIT ENHANCEMENTS FGIC 30.6% FSA 26.5 AMBAC 25.9 MBIA 14.9 US Gov't Backed 2.1 Data as of October 31, 2006.

Organization and Accounting Policies Morgan Stanley Insured California Municipal Securities (the "Trust") is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company. The Trust's investment objective is to provide current income which is exempt from both federal and California income taxes. The Trust was organized as a Massachusetts business trust on October 14, 1993 and commenced operations on February 28, 1994. The following is a summary of significant accounting policies: A. Valuation of Investments -- (1) portfolio securities are valued by an outside independent pricing service approved by the Trustees. The pricing service uses both a computerized grid matrix of tax-exempt securities and evaluations by its staff, in each case based on information concerning market transactions and quotations from dealers which reflect the mean between the last reported bid and asked price. The portfolio securities are thus valued by reference to a combination of transactions and quotations for the same or other securities believed to be comparable in quality, coupon, maturity, type of issue, call provisions, trading characteristics and other features deemed to be relevant. The Trustees believe that timely and reliable market quotations are generally not readily available for purposes of valuing tax-exempt securities and that the valuations supplied by the pricing service are more likely to approximate the fair value of such securities; (2) futures are valued at the latest sale price on the commodities exchange on which they trade unless it is determined that such price does not reflect their market value, in which case they will be valued at their fair value as determined in good faith under procedures established by and under the supervision of the Trustees; and (3) short-term debt securities having a maturity date of more than sixty days at time of purchase are valued on a mark-to-market basis until sixty days prior to maturity and thereafter at amortized cost based on their value on the 61st day. Short-term debt securities having a maturity date of sixty days or less at the time of purchase are valued at amortized cost. B. Accounting for Investments -- Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on security transactions are determined by the identified cost method. Discounts are accreted and premiums are amortized over the life of the respective securities. Interest income is accrued daily. C. Futures Contracts -- A futures contract is an agreement between two parties to buy and sell financial instruments or contracts based on financial indices at a set price on a future date. Upon entering into such a contract, the Trust is required to pledge to the broker cash, U.S. Government securities or other liquid portfolio securities equal to the minimum initial margin requirements of the applicable futures exchange. Pursuant to the contract, the Trust agrees to receive from or pay to the 14 Morgan Stanley Insured California Municipal Securities NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 continued broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments known as variation margin are recorded by the Trust as unrealized gains and losses. Upon closing of the contract, the Trust realizes a gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. D. Federal Income Tax Policy -- It is the Trust's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable and nontaxable income to its shareholders. Accordingly, no federal income tax provision is required. E. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. F. Use of Estimates -- The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates. 2. Investment Advisory/Administration Agreements Pursuant to an Investment Advisory Agreement, with Morgan Stanley Investment Advisors Inc. (the "Investment Adviser"), the Trust pays an advisory fee, calculated weekly and payable monthly, by applying the annual rate of 0.27% to the Trust's weekly net assets. Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the Administrator"), an affiliate of the Investment Adviser, the Trust pays an administration fee, calculated weekly and payable monthly, by applying the annual rate of 0.08% to the Trust's weekly net assets. 3. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended October 31, 2006 aggregated $2,552,473 and $5,633,744, respectively. Morgan Stanley Trust, an affiliate of the Investment Adviser and Administration, is the Trust's transfer agent. The Trust has an unfunded Deferred Compensation Plan (the "Compensation Plan") which allows each independent Trustee to defer payment of all, or a portion, of the fees he or she receives for serving on the Board of Trustees. Each eligible Trustee generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and 15 Morgan Stanley Insured California Municipal Securities NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 continued distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Trust. 4. Preferred Shares of Beneficial Interest The Trust is authorized to issue up to 1,000,000 non-participating preferred shares of beneficial interest having a par value of $.01 per share, in one or more series, with rights as determined by the Trustees, without approval of the common shareholders. The preferred shares have a liquidation value of $50,000 per share plus the redemption premium, if any, plus accumulated but unpaid dividends, whether or not declared, thereon to the date of distribution. The Trust may redeem such shares, in whole or in part, at the original purchase price of $50,000 per share plus accumulated but unpaid dividends, whether or not declared, thereon to the date of redemption. Upon issuance, the Trust will be subject to certain restrictions relating to the preferred shares. Failure to comply with these restrictions could preclude the Trust from declaring any distributions to common shareholders or purchasing common shares and/or could trigger the mandatory redemption of preferred shares at liquidation value. The preferred shares, entitled to one vote per share, generally vote with the common shares but vote separately as a class to elect two Trustees and on any matters affecting the rights of the preferred shares. As of October 31, 2006, there were no preferred shares outstanding. 5. Common Shares of Beneficial Interest Transactions in common shares of beneficial interest were as follows: CAPITAL PAID IN EXCESS OF SHARES PAR VALUE PAR VALUE ---------- --------- ----------- Balance, October 31, 2004................................... 3,710,113 $37,101 $52,626,096 Treasury shares purchased and retired (weighted average discount 7.99%)*..........................................

Dividends to Common Shareholders On September 26, 2006, the Trust declared the following dividends from net investment income: AMOUNT RECORD PAYABLE PER SHARE DATE DATE --------- ---------------- ----------------- $0.05 November 3, 2006 November 17, 2006 $0.05 December 8, 2006 December 22, 2006 7. Expense Offset The expense offset represents a reduction of the fees and expenses for interest earned on cash balances maintained by the Trust with the transfer agent and the custodian. 8. Purposes of and Risks Relating to Certain Financial Instruments The Trust may invest a portion of its assets in inverse floating rate instruments, either through outright purchases of inverse floating rate securities or through the transfer of bonds to a dealer trust in exchange for cash and residual interests in the dealer trust. These investments are typically used by the Trust in seeking to enhance the yield of the portfolio. These instruments typically involve greater risks than a fixed rate municipal bond. In particular, these instruments are acquired through leverage or may have leverage embedded in them and therefore involve many of the risks associated with leverage. Leverage is a speculative technique that may expose the Trust to greater risk and increased costs. Leverage may cause the Trust's net asset value to be more volatile than if it had not been leveraged because leverage tends to magnify the effect of any increases or decreases in the value of the Trust's portfolio securities. The use of leverage may also cause the Trust to liquidate portfolio positions when it may not be advantageous to do so in order to satisfy its obligations with respect to inverse floating rate instruments. To hedge against adverse interest rate changes, the Trust may invest in financial futures contracts or municipal bond index futures contracts ("futures contracts"). These futures contracts involve elements of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The Trust bears the risk of an unfavorable change in the value of the underlying securities. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts. 9. Federal Income Tax Status The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations which may differ from generally accepted accounting principles. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification. Dividends and distributions which exceed net investment income and net realized capital gains for tax purposes are reported as distributions of paid-in-capital. 17 Morgan Stanley Insured California Municipal Securities NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 continued The tax character of distributions paid was as follows: FOR THE YEAR FOR THE YEAR ENDED ENDED OCTOBER 31, 2006 OCTOBER 31, 2005 ---------------- ---------------- Tax-exempt income........................................... $2,122,683 $2,395,477 Ordinary income............................................. 134,039 10,185 Long-term capital gains..................................... 1,142,737 463,024 ---------- ---------- Total distributions......................................... $3,399,459 $2,868,686 ========== ========== As of October 31, 2006, the tax-basis components of accumulated earnings were as follows: Undistributed tax-exempt income............................. $ 311,891 Undistributed long-term gains............................... 142,681 ---------- Net accumulated earnings.................................... 454,572 Temporary differences....................................... (123) Net unrealized appreciation................................. 2,823,755 ---------- Total accumulated earnings.................................. $3,278,204 ========== As of October 31, 2006, the Trust had temporary book/tax differences primarily attributable to book amortization of discounts on debt securities and mark-to-market of open futures contracts. 10. New Accounting Pronouncements In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position must meet before being recognized in the financial statements. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Trust will adopt FIN 48 for the fiscal year ending 2008 and the impact to the Trust's financial statements, if any, is currently being assessed. In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Trust's financial statement disclosures. 18 Morgan Stanley Insured California Municipal Securities FINANCIAL HIGHLIGHTS Selected ratios and per share data for a common share of beneficial interest outstanding throughout each period: FOR THE YEAR ENDED OCTOBER 31 ----------------------------------------------------------- 2006 2005 2004 2003 2002 ------- ------- ------- ------- ------- Selected Per Share Data: Net asset value, beginning of period.............. $15.17 $15.35 $15.24 $15.56 $16.00 ------ ------ ------ ------ ------ Income (loss) from investment operations: Net investment income*........................ 0.59 0.62 0.66 0.67 0.69 Net realized and unrealized gain (loss)....... 0.32 (0.05) 0.25 (0.07) (0.01) ------ ------ ------ ------ ------ Total income from investment operations........... 0.91 0.57 0.91 0.60 0.68 ------ ------ ------ ------ ------ Less dividends and distributions from: Net investment income.........................

These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Morgan Stanley Insured California Municipal Securities as of October 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. Deloitte & Touche LLP New York, New York January 12, 2007 20 Morgan Stanley Insured California Municipal Securities SHAREHOLDER VOTING RESULTS (UNAUDITED) On June 20, 2006, an annual meeting of the Trust's shareholders was held for the purpose of voting on the following matter, the results of which were as follows: Election of Trustees by all Shareholders: # OF SHARES ---------------------------------------------- FOR WITHHELD ABSTAIN ---------------------------------------------- Frank L.

Broker "non-votes" are shares held in street name for which the broker indicates that instructions have not been received from the beneficial owners or other persons entitled to vote and for which the broker does not have discretionary voting authority. The following Trustees were not standing for reelection at this meeting: Michael Bozic, Edwin J. Garn, James F. Higgins and Michael E. Nugent. 21 Morgan Stanley Insured California Municipal Securities REVISED INVESTMENT POLICY (UNAUDITED) THE TRUSTEES APPROVED THE FOLLOWING INVESTMENT POLICY: INTEREST RATE TRANSACTIONS. The Trust may enter into interest rate swaps and may purchase or sell interest rate caps, floors and collars. The Trust expects to enter into these transactions primarily to manage interest rate risk, hedge portfolio positions and preserve a return or spread on a particular investment or portion of its portfolio. The Trust may also enter into these transactions to protect against any increase in the price of securities the Trust anticipates purchasing at a later date. The Trust does not intend to use these transactions as speculative investments and will not enter into interest rate swaps or sell interest rate caps or floors where it does not own or have the right to acquire the underlying securities or other instruments providing the income stream the Trust may be obligated to pay. Interest rate swaps involve the exchange by the Trust with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed-rate payments. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index exceeds a predetermined interest rate, to receive payments of interest on a contractually-based principal amount from the party selling the interest rate cap. 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 contractually-based principal amount from the party selling the interest rate floor. An interest rate collar combines the elements of purchasing a cap and selling a floor. The collar protects against an interest rate rise above the maximum amount but foregoes the benefit of an interest rate decline below the minimum amount. The Trust may enter into interest rate swaps, caps, floors and collars on either an asset-based or liability-based basis, and will usually enter into interest rate swaps on a net basis, i.e., the two payment streams are netted out, with the Trust receiving or paying, as the case may be, only the net amount of the two payments. The net amount of the excess, if any, of the Trust's obligations over its entitlements with respect to each interest rate swap will be accrued on a daily basis and the Trust segregates an amount of cash and/or liquid securities having an aggregate net asset value at least equal to the accrued excess. If the Trust enters into an interest rate swap on other than a net basis, the Trust would segregate the full amount accrued on a daily basis of the Trust's obligations with respect to the swap. Interest rate transactions do not constitute senior securities under the 1940 Act when the Trust segregates assets to cover the obligations under the transactions. The Trust will enter into interest rate swap, cap or floor transactions only with counterparties approved by the Trust's Board of Trustees. The Adviser will monitor the creditworthiness of counterparties to the Trust's interest rate swap, cap, floor and collar transactions on an ongoing basis. If there is a default by the other party to such a transaction, the Trust will have contractual remedies pursuant to the agreements related to the transaction. To the extent the Trust sells (i.e., writes) caps, floors and collars, it will segregate cash and/or liquid securities having an aggregate net asset value at least 22 Morgan Stanley Insured California Municipal Securities REVISED INVESTMENT POLICY (UNAUDITED) continued equal to the full amount, accrued on a daily basis, of the Trust's net obligations with respect to the caps, floors or collars. The use of interest rate swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Adviser is incorrect in its forecasts of the market values, interest rates and other applicable factors, the investment performance of the Trust would diminish compared with what it would have been if these investment techniques were not used. The use of interest rate swaps, caps, collars and floors may also have the effect of shifting the recognition of income between current and future periods. These transactions do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that the Trust is contractually obligated to make. If the other party to an interest rate swap defaults, the Trust's risk of loss consists of the net amount of interest payments that the Trust contractually is entitled to receive. 23 Morgan Stanley Insured California Municipal Securities TRUSTEE AND OFFICER INFORMATION (UNAUDITED) Independent Trustees: Number of Portfolios in Fund Complex Position(s) Term of Office Overseen by Name, Age and Address of Held with and Length of Principal Occupation(s) During Independent Independent Trustee Registrant Time Served* Past 5 Years Trustee** --------------------------------------- ----------- -------------- ------------------------------ ------------- Frank L.

STATEMENT OF PRINCIPLES The Audit Committee of the Board is required to review and, in its sole discretion, pre-approve all Covered Services to be provided by the Independent Auditors to the Fund and Covered Entities in order to assure that services performed by the Independent Auditors do not impair the auditor's independence from the Fund. The SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee's administration of the engagement of the independent auditor. The SEC's rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid. Proposed services either: may be pre-approved without consideration of specific case-by-case services by the Audit Committee ("general pre-approval"); or require the specific pre-approval of the Audit Committee or its delegate ("specific pre-approval"). The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the Independent Auditors. As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee (or by any member of the Audit Committee to which pre-approval authority has been delegated) if it is to be provided by the Independent Auditors. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee. The appendices to this Policy describe the Audit, Audit-related, Tax and All Other services that have the general pre-approval of the Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers and provides a different period and states otherwise. The Audit Committee will annually review and pre-approve the services that may be provided by the Independent Auditors without obtaining specific pre-approval from the Audit Committee. The Audit Committee will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations. ---------- (1) This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and Procedures (the "Policy"), adopted as of the date above, supersedes and replaces all prior versions that may have been adopted from time to time. 4 The purpose of this Policy is to set forth the policy and procedures by which the Audit Committee intends to fulfill its responsibilities. It does not delegate the Audit Committee's responsibilities to pre-approve services performed by the Independent Auditors to management. The Fund's Independent Auditors have reviewed this Policy and believes that implementation of the Policy will not adversely affect the Independent Auditors' independence. 2. DELEGATION As provided in the Act and the SEC's rules, the Audit Committee may delegate either type of pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting. 3. AUDIT SERVICES The annual Audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee. Audit services include the annual financial statement audit and other procedures required to be performed by the Independent Auditors to be able to form an opinion on the Fund's financial statements. These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit. The Audit Committee will approve, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, Fund structure or other items. In addition to the annual Audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other Audit services, which are those services that only the Independent Auditors reasonably can provide. Other Audit services may include statutory audits and services associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4, etc.), periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings. The Audit Committee has pre-approved the Audit services in Appendix B.1. All other Audit services not listed in Appendix B.1 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 4. AUDIT-RELATED SERVICES Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Fund's financial statements and, to the extent they are Covered Services, the Covered Entities or that are traditionally performed by the Independent Auditors. Because the Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor and is consistent with the SEC's rules on auditor independence, the Audit Committee may grant general pre-approval to Audit-related services. Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters 5 not classified as "Audit services"; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting requirements under Forms N-SAR and/or N-CSR. The Audit Committee has pre-approved the Audit-related services in Appendix B.2. All other Audit-related services not listed in Appendix B.2 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 5. TAX SERVICES The Audit Committee believes that the Independent Auditors can provide Tax services to the Fund and, to the extent they are Covered Services, the Covered Entities, such as tax compliance, tax planning and tax advice without impairing the auditor's independence, and the SEC has stated that the Independent Auditors may provide such services. Pursuant to the preceding paragraph, the Audit Committee has pre-approved the Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 6. ALL OTHER SERVICES The Audit Committee believes, based on the SEC's rules prohibiting the Independent Auditors from providing specific non-audit services, that other types of non-audit services are permitted. Accordingly, the Audit Committee believes it may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, would not impair the independence of the auditor and are consistent with the SEC's rules on auditor independence. The Audit Committee has pre-approved the All Other services in Appendix B.4. Permissible All Other services not listed in Appendix B.4 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 7. PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS Pre-approval fee levels or budgeted amounts for all services to be provided by the Independent Auditors will be established annually by the Audit Committee. Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee. The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services. 8. PROCEDURES All requests or applications for services to be provided by the Independent Auditors that do not require specific approval by the Audit Committee will be submitted to the Fund's Chief Financial Officer and must include a detailed description of the services to be 6 rendered. The Fund's Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee. The Audit Committee will be informed on a timely basis of any such services rendered by the Independent Auditors. Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the Independent Auditors and the Fund's Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC's rules on auditor independence. The Audit Committee has designated the Fund's Chief Financial Officer to monitor the performance of all services provided by the Independent Auditors and to determine whether such services are in compliance with this Policy. The Fund's Chief Financial Officer will report to the Audit Committee on a periodic basis on the results of its monitoring. Both the Fund's Chief Financial Officer and management will immediately report to the chairman of the Audit Committee any breach of this Policy that comes to the attention of the Fund's Chief Financial Officer or any member of management. 9. ADDITIONAL REQUIREMENTS The Audit Committee has determined to take additional measures on an annual basis to meet its responsibility to oversee the work of the Independent Auditors and to assure the auditor's independence from the Fund, such as reviewing a formal written statement from the Independent Auditors delineating all relationships between the Independent Auditors and the Fund, consistent with Independence Standards Board No. 1, and discussing with the Independent Auditors its methods and procedures for ensuring independence. 10. COVERED ENTITIES Covered Entities include the Fund's investment adviser(s) and any entity controlling, controlled by or under common control with the Fund's investment adviser(s) that provides ongoing services to the Fund(s). Beginning with non-audit service contracts entered into on or after May 6, 2003, the Fund's audit committee must pre-approve non-audit services provided not only to the Fund but also to the Covered Entities if the engagements relate directly to the operations and financial reporting of the Fund. This list of Covered Entities would include: Morgan Stanley Retail Funds Morgan Stanley Investment Advisors Inc. Morgan Stanley & Co. Incorporated Morgan Stanley DW Inc. Morgan Stanley Investment Management Inc. Morgan Stanley Investment Management Limited Morgan Stanley Investment Management Private Limited Morgan Stanley Asset & Investment Trust Management Co., Limited Morgan Stanley Investment Management Company Van Kampen Asset Management Morgan Stanley Services Company, Inc. Morgan Stanley Distributors Inc. Morgan Stanley Trust FSB 7 Morgan Stanley Institutional Funds Morgan Stanley Investment Management Inc. Morgan Stanley Investment Advisors Inc. Morgan Stanley Investment Management Limited Morgan Stanley Investment Management Private Limited Morgan Stanley Asset & Investment Trust Management Co., Limited Morgan Stanley Investment Management Company Morgan Stanley & Co. Incorporated Morgan Stanley Distribution, Inc. Morgan Stanley AIP GP LP Morgan Stanley Alternative Investment Partners LP (e)(2) Beginning with non-audit service contracts entered into on or after May 6, 2003, the audit committee also is required to pre-approve services to Covered Entities to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Registrant. 100% of such services were pre-approved by the audit committee pursuant to the Audit Committee's pre-approval policies and procedures (attached hereto). (f) Not applicable. (g) See table above. (h) The audit committee of the Board of Trustees has considered whether the provision of services other than audit services performed by the auditors to the Registrant and Covered Entities is compatible with maintaining the auditors' independence in performing audit services. Item 5. Audit Committee of Listed Registrants. (a) The Trust has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act whose members are: Frank Bowman, Wayne Hedien, Joseph Kearns, Michael Nugent and Allen Reed. (b) Not applicable. Item 6. See Item 1. Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies. 8 The Trust invests in exclusively non-voting securities and therefore this item is not applicable. Item 8. Portfolio Managers of Closed-End Management Investment Companies PORTFOLIO MANAGEMENT. As of the date of this report, the Trust is managed by members of the Municipal Fixed Income team. The team consists of portfolio managers and analysts. Current members of the team jointly and primarily responsible for the day-to-day management of the Trust's portfolio and the overall execution of the strategy of the Trust are James F. Willison, a Managing Director of the Investment Adviser and Joseph R. Arcieri and John Reynoldson, Executive Directors of the Investment Adviser. Mr. Willison has been associated with the Investment Adviser in an investment management capacity since January 1980 and began managing the Trust at inception. Mr. Arcieri has been associated with the Investment Adviser in an investment management capacity since January 1986 and began managing the Trust in February 1997. Mr. Reynoldson has been associated with the Investment Adviser in an investment management capacity since April 1987 and began managing the Trust in January 2002. The composition of the team may change from time to time. OTHER ACCOUNTS MANAGED BY THE PORTFOLIO MANAGERS The following information is as of October 31, 2006: Mr. Willison managed 22 mutual funds with a total of approximately $7.4 billion in assets; no pooled investment vehicles other than mutual funds; and no other accounts. Mr. Arcieri managed 19 mutual funds with a total of approximately $5.7 billion in assets; no pooled investment vehicles other than mutual funds; and no other accounts. Mr. Reynoldson managed 19 mutual funds with a total of approximately $7.7 billion in assets; no pooled investment vehicles other than mutual funds; and no other accounts. Because the portfolio managers manage assets for other investment companies, pooled investment vehicles, and/or other accounts (including institutional clients, pension plans and certain high net worth individuals), there may be an incentive to favor one client over another resulting in conflicts of interest. For instance, the Investment Adviser may receive fees from certain accounts that are higher than the fee it receives from the Trust, or it may receive a performance-based fee on certain accounts. In those instances, the portfolio manager may have an incentive to favor the higher and/or performance-based fee accounts over the Trust. The Investment Adviser has adopted trade allocation and other policies and procedures that it believes are reasonably designed to address these and other conflicts of interest. 9 PORTFOLIO MANAGER COMPENSATION STRUCTURE Portfolio managers receive a combination of base compensation and discretionary compensation, comprised of a cash bonus and several deferred compensation programs described below. The methodology used to determine portfolio manager compensation is applied across all funds/accounts managed by the portfolio manager. BASE SALARY COMPENSATION. Generally, portfolio managers receive base salary compensation based on the level of their position with the Investment Adviser. DISCRETIONARY COMPENSATION. In addition to base compensation, portfolio managers may receive discretionary compensation. Discretionary compensation can include: - Cash Bonus. - Morgan Stanley's Equity Incentive Compensation Program (EICP) awards -- a mandatory program that defers a portion of discretionary year-end compensation into restricted stock units or other awards based on Morgan Stanley common stock that are subject to vesting and other conditions. - Investment Management Alignment Plan (IMAP) awards -- a mandatory program that defers a portion of discretionary year-end compensation and notionally invests it in designated Funds advised by the Investment Adviser or its affiliates. The award is subject to vesting and other conditions. Portfolio managers must notionally invest a minimum of 25% to a maximum of 100% of the IMAP deferral into a combination of the designated open-end mutual funds they manage that are included in the IMAP fund menu, which may or may not include the Trust. - Voluntary Deferred Compensation Plans -- voluntary programs that permit certain employees to elect to defer a portion of their discretionary year-end compensation and directly or notionally invest the deferred amount: (1) across a range of designated investment Funds, including Funds advised by the Investment Adviser or its affiliates; and/or (2) in Morgan Stanley stock units. Several factors determine discretionary compensation, which can vary by portfolio management team and circumstances. In order of relative importance, these factors include: - Investment performance. A portfolio manager's compensation is linked to the pre-tax investment performance of the funds/accounts managed by the portfolio manager. Investment performance is calculated for one-, three- and five-year periods measured against a fund's/account's primary benchmark, indices and/or peer groups where applicable. Generally, the greatest weight is placed on the three- and five-year periods. 10 - Revenues generated by the investment companies, pooled investment vehicles and other accounts managed by the portfolio manager. - Contribution to the business objectives of the Investment Adviser. - The dollar amount of assets managed by the portfolio manager. - Market compensation survey research by independent third parties. - Other qualitative factors, such as contributions to client objectives. - Performance of Morgan Stanley and Morgan Stanley Investment Management, and the overall performance of the investment team(s) of which the portfolio manager is a member.

Submission of Matters to a Vote of Security Holders Not applicable. Item 11. Controls and Procedures a) The Trust's principal executive officer and principal financial officer have concluded that the Trust's disclosure controls and procedures are sufficient to provide reasonable assurance that information required to be disclosed by the Trust in this Form N-CSR was recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's ("SEC") rules and forms or by the SEC staff, based upon such officers' evaluation of these controls and procedures as of January 12, which is a date within 90 days of the filing date of the report. The Trust's principal executive officer and principal financial officer have also concluded that the Trust's disclosure controls and procedures designed to ensure that information required to be disclosed by the Trust in this Form N-CSR is accumulated and communicated to the Trust's management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure were effective. Management of the Trust has determined that as of and prior to October 31, 2006, the Trust's fiscal year end, the Trust had a deficiency in its internal control over financial reporting related to the review, analysis and determination of whether certain transfers of municipal securities qualified for sale accounting under the provisions of Statement of Financial Accounting Standards No. 140 "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." As a result, the Trust's independent registered public accountants advised the Trust that this control deficiency represented a material weakness in internal control over financial reporting as of October 31, 2006. Since October 31, 2006, and prior to the issuance of the Trust's annual report, management has revised its disclosure controls and procedures and its internal control over financial reporting in order to improve the controls' effectiveness to ensure that transactions in transfers of municipal securities are accounted for properly. Management notes that other investment companies investing in similar investments over the same time periods had been accounting for such investments in a similar manner as the Trust. Accordingly, other investment companies are also concluding that there was a material weakness in their internal control over financial reporting of such investments.
