UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 FORM N-CSR CERTIFIED SHAREHOLDER REPORT OF REGISTERED MANAGEMENT INVESTMENT COMPANIES Investment Company Act file number: 811-07111 Morgan Stanley Insured California Municipal Securities (Exact name of registrant as specified in charter) 1221 Avenue of the Americas, New York, New York 10020 (Address of principal executive offices) (Zip code) Ronald E. Robison 1221 Avenue of the Americas, New York, New York 10020 (Name and address of agent for service) Registrant's telephone number, including area code: 212-762-4000 Date of fiscal year end: October 31, 2003 Date of reporting period: April 30, 2003 Item 1. Report to Stockholders. Morgan Stanley Insured California Municipal Securities LETTER TO THE SHAREHOLDERS - APRIL 30, 2003 Dear Shareholder: During the six-month period ended April 30, 2003, U.S. economic growth was positive but disappointing. The pattern of the recovery remained uneven with many indicators fluctuating between strength and weakness. The military conflict in Iraq and the ongoing war against terrorism cast a shadow over the economy and the financial markets. The sluggish economy and uncertain geopolitical outlook generally favored bonds and led to lower interest rates throughout the period. Consumer spending was the best-performing sector of the economy last year. Mortgage refinancing and low auto loan rates helped keep Americans buying. By year-end a growing apprehension about Iraq began to dominate investor sentiment and consumer confidence waned. The most noticeable impact of the evolving war risk was a spike in oil prices that had a dampening effect similar to a tax increase. Confidence was also shaken when unemployment reached an eight-year high. To guard against further downside risks, the Federal Reserve Board lowered the federal funds rate from 1.75 to 1.25 percent in early November. This marked the first change by the central bank in almost a year. Early in 2003, the Bush administration proposed several tax relief measures to bolster the economy. Uncertainty prior to the invasion of Iraq slowed economic activity in March. However, resolution of the conflict prompted the financial markets again to focus on the economic outlook. Municipal Market Conditions The yield on the 30-year insured municipal bond index continued to trend lower over the six-month period ended April 30, 2003. The yield declined from a high of 5.10 percent in November 2002 to a low of 4.70 percent in April. Throughout the period, the municipal yield curve was at or near its steepest level in 25 years. The pickup along the yield curve for extending maturities from one to 30 years was 350 basis points on April 30, 2003. The ratio of municipal yields as a percentage of U.S. Treasury yields is used to gauge the relative value of municipals. In October 2002 the ratio of 30-year insured municipal bond yields to 30-year Treasuries moved above 100 percent, remaining there through the first quarter of 2003. In April the ratio fell to 99 percent as the Treasury flight-to-quality rally subsided. This still-high ratio indicated that municipals were relatively cheaper than Treasuries. The President's tax proposals, which included elimination of taxation on dividend income and acceleration of a reduction in tax brackets, affected the municipal market. The tax-exempt bond Morgan Stanley Insured California Municipal Securities LETTER TO THE SHAREHOLDERS - APRIL 30, 2003 continued market reacted to potential tax-reform risk by adjusting the relationship of tax-exempt issues to taxables. Long-term municipal volume, as reported in The Bond Buyer, increased to a record $357 billion in 2002 as state and local governments took advantage of lower interest rates to meet cash flow needs and refinance outstanding debt. In the first four months of 2003, new-issue volume reached a record $113 billion, 21 percent above last year's level. We expect this pace to continue throughout the year as budgetary problems force states and municipalities to borrow. California's share of national volume increased to 19 percent. Performance The net asset value (NAV) of Morgan Stanley Insured California Municipal Securities (ICS) decreased from $15.56 to $15.47 per share for the six months ended April 30, 2003. Based on this change, plus the reinvestment of tax-free dividends totaling $0.345 per share, a short-term capital gain distribution of $0.041 per share and a long-term capital gain distribution of $0.231 per share, the Trust's total NAV return was 3.83 percent. ICS's price on the New York Stock Exchange (NYSE) decreased from $14.15 to $13.92 per share during the same period. Based on this change plus reinvestment of dividends and distributions, ICS's total market value return was 2.73 percent. On April 30, 2003, ICS's market price was at a 10.02 percent discount to its NAV. Monthly dividends for the second quarter of 2003, declared in March, were unchanged at $0.0575 per share. The dividend reflects the level of the Trust's undistributed net investment income and projected earnings. The Trust's level of undistributed net investment income was $0.113 per share on April 30, 2003, versus $0.128 per share six months earlier. Past performance is no guarantee of future results. Portfolio Structure The Trust's net assets of $59 million were diversified among 12 long-term sectors and 33 credits. Issues in three essential service sectors: general obligation, water and sewer and municipal electric accounted for 48 percent of the long-term portfolio. Importantly, the Trust has avoided bonds secured by tobacco settlement payments. Many states including California have issued bonds backed by their entitlement to revenues from the Master Settlement Agreement with tobacco companies. A class action judgment against Philip Morris, a major participant in the agreement, has created uncertainty about the company's ability to meet its obligations. 2 Morgan Stanley Insured California Municipal Securities LETTER TO THE SHAREHOLDERS - APRIL 30, 2003 continued At the end of April the portfolio's average maturity was 19 years. ICS's duration, a measure of sensitivity to interest rate changes, was 6.9 years. The accompanying charts provide current information on the portfolio's credit enhancements, maturity distribution and sector concentrations. Optional redemption provisions by year of the call and respective cost (book) yields are also charted. The Trust's procedure for reinvestment of 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, which ever is lower at the time of purchase. During the six-month period ended April 30, 2003 the Trust purchased and retired 40,600 shares of common stock at a weighted average market discount of 8.87 percent. We appreciate your ongoing support of Morgan Stanley Insured California Municipal Securities and look forward to continuing to serve your investment needs. Very truly yours, /s/ CHARLES A.

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 bid side of the market each day. 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; (2) futures are valued at the latest sale price on the commodities exchange on which they trade unless the Trustees determine 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 12 Morgan Stanley Insured California Municipal Securities NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2003 (UNAUDITED) continued receive from or pay to the 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. 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 financial reporting purposes but not for tax purposes are reported as dividends in excess of net investment income or distributions in excess of net realized capital gains. To the extent they exceed net investment income and net realized capital gains for tax purposes, they are reported as distributions of paid-in-capital. 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 applicable to common shareholders. 13 Morgan Stanley Insured California Municipal Securities NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2003 (UNAUDITED) continued 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, 2003 aggregated $6,584,800 and $9,110,965, respectively. Included in the aforementioned are sales of $1,013,650 with Morgan Stanley California Insured Municipal Income Trust, an affiliate of the Investment Manager. Morgan Stanley Trust, an affiliate of the Investment Manager, is the Trust's transfer agent. At April 30, 2003, the Trust had transfer agent fees and expenses payable of approximately $3,300. 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, 2003, there were no preferred shares outstanding. 14 Morgan Stanley Insured California Municipal Securities NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2003 (UNAUDITED) continued 5.
