FUND REPORT For the six-month period ended April 30, 2004 MARKET CONDITIONS The U.S. economy continued to show improvement over the six-month period under review. On the positive side, gross domestic product growth topped 4 percent in both quarters. While strength in output has historically led to higher interest rates, yields remained stubbornly low across the curve. These yields reflected low levels of observed inflation in the economy and gradual improvement in employment. The Federal Open Market Committee maintained its accommodative monetary policy. Surprising job growth in March, combined with escalating oil prices, led investors to anticipate that the Fed would raise interest rates sooner rather than later. Yet at its April meeting, the Federal Reserve did not change its short-term lending rate but did signal a prospective shift in policy. As a result, bond yields spiked across sectors and maturities. The supply of new municipal bonds in calendar 2003 reached record levels as municipalities took advantage of historically low interest rates. Many cities and states reduced expenditures by refinancing existing debt at lower yields. In other cases, municipalities attempted to meet budget needs by issuing additional debt. Then in the first months of 2004, bond sales began to slow. Low interest rates also had an impact on the demand for municipal bonds. Retail and mutual fund activity slowed as holders of municipal bonds saw little reason to sell bonds purchased at higher yields and reinvest at historically low yields. However, insurance companies and hedge funds purchased municipal bonds based on their attractiveness relative to taxable securities. Additionally, investors stretched for yield by buying lower-rated bonds, causing credit spreads to tighten. California remained in the municipal credit market spotlight during this period. In March, voters approved a referendum authorizing the sale of up to $15 billion of economic recovery bonds to refinance the state's accumulated budget deficit. This led the major ratings agencies to improve the outlook but not the rating for the state's beleaguered bonds. S&P shifted its stance from a stable to a positive outlook and Moody's changed from a negative to a stable outlook. PERFORMANCE ANALYSIS The net asset value (NAV) of Morgan Stanley Insured California Municipal Securities (ICS) decreased from $15.24 to $14.91 per share for the six-month period ended April 30, 2004. Based on this change plus reinvestment of tax-free dividends totaling $0.315 per share, short-term capital gains of $0.004 per share and long-term capital gains of $0.199 per share, the Trust's total NAV return was 1.49 percent. The Trust's value on the New York Stock Exchange (NYSE) decreased from $13.83 to $13.42 per share during the same period. Based on this change plus reinvestment of dividends and distributions, the Trust's total market return was 0.66 percent. On April 30, 2004, ICS's NYSE market price was at a 9.99 percent discount to its NAV. Past performance is no guarantee of future results. Monthly dividends for the second quarter of 2004, declared in March, were unchanged at $0.0525 per share. The dividend reflects the level of the Trust's 2 undistributed net investment income and projected earnings power. The Trust's level of undistributed net investment income was $0.133 per share on April 30, 2004, versus $0.112 per share six months earlier. The Trust's duration* was targeted to be shorter than its benchmark index. The duration adjusted for leverage was 8.2 years. Treasury futures were sold to reduce interest-rate exposure without raising the level of cash in the portfolio. We maintained an average tax-exempt bond maturity objective of 20 years to take advantage of the steepness of the municipal yield curve. Revenue bonds in sectors with reliable income streams from essential services such as municipal electric, transportation and water and sewer systems were emphasized. The Trust's net assets of nearly $56 million were diversified across 31 credits in 11 long-term sectors. The Trust's procedure for reinvesting all dividends and distributions in 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. ---------------------------------------------------- * 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.

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 11 Morgan Stanley Insured California Municipal Securities NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2004 (UNAUDITED) 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 Management Agreement Pursuant to an Investment Management Agreement, with Morgan Stanley Investment Advisors Inc. (the "Investment Manager"), the Trust pays the Investment Manager a management fee, calculated weekly and payable monthly, by applying the annual rate of 0.35% 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 six months ended April 30, 2004 aggregated $3,119,180 and $5,385,280, respectively. Morgan Stanley Trust, an affiliate of the Investment Manager, is the Trust's transfer agent. At April 30, 2004, the Trust had transfer agent fees and expenses payable of approximately $1,800. Effective April 1, 2004, the Trust began 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 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 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. 12 Morgan Stanley Insured California Municipal Securities NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2004 (UNAUDITED) continued 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 April 30, 2004, 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, 2002................................... 3,911,313 $39,113 $55,421,069 Treasury shares purchased and retired (weighted average discount 8.44%)*..........................................

Dividends to Common Shareholders On March 30, 2004, the Trust declared the following dividends from net investment income: AMOUNT RECORD PAYABLE PER SHARE DATE DATE --------- ------------ ------------- $0.0525 May 7, 2004 May 21, 2004 $0.0525 June 4, 2004 June 18, 2004 7. Expense Offset The expense offset represents a reduction of the custodian fees for earnings on cash balances maintained by the Trust. 8. Risks Relating to Certain Financial Instruments The Trust may invest a portion of its assets in residual interest bonds, which are inverse floating rate municipal obligations. The prices of these securities are subject to greater market fluctuations during periods of changing prevailing interest rates than are comparable fixed rate obligations. 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. As of October 31, 2003, 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. 14 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 SIX FOR THE YEAR ENDED OCTOBER 31 MONTHS ENDED --------------------------------------------------------------- APRIL 30, 2004 2003 2002 2001 2000 1999 -------------- ------- ------- ------- ------- ------- (unaudited) Selected Per Share Data: Net asset value, beginning of period..... $15.24 $15.56 $16.00 $15.24 $14.42 $16.00 ------ ------ ------ ------- ------- ------- Income (loss) from investment operations: Net investment income*............... 0.33 0.67 0.69 0.78 0.76 0.74 Net realized and unrealized gain (loss)...
