Economic Environment During the six-month period ended March 31, 2003, equity and fixed income markets and the domestic economy continued to be influenced strongly by developments outside of the financial sector. The uncertainty that surrounded the effectiveness of the weapons inspections by the United Nations and the eventual onset of war with Iraq in mid-March weighed heavily on consumer and corporate spending. Despite the increased volatility in the equity markets because of geopolitical uncertainty, the Dow Jones Industrial Average and the NASDAQ Composite Index were able to post positive gains for the period. However, by March 31, 2003, both indexes were well off the highs reached in late November 2002. Fixed income investors favored the very short end of the U.S. Treasury yield curve because of its relative safety. Six-month and two-year U.S. Treasury bills experienced solid gains that lowered yields on these instruments 43 basis points (.43%) and 31 basis points, respectively. Finally, the Federal Open Market Committee, has met four times since September 30, 2002, lowering interest rates 50 basis points at its meeting on November 6, 2002 and bringing the Federal Funds borrowing rate to a historic low of 1.25%. Interestingly, at the Federal Open Market Committee meeting on March 18, 2003, the Federal Reserve Board chose not to issue its customary stated bias, which typically characterizes the committee's current risk assessment for the economy. This may have left the door open for the Federal Reserve Board to cut the Federal Funds rate between meetings should conditions warrant. Specific to California, the state's financial situation continued to concern the major rating agencies during the period as both its long-term and short-term credit ratings were lowered further. At March 31, 2003, the state legislature continued to debate significant tax increases and budget reductions to close an estimated $21 billion budget deficit for the current fiscal year. The treasurer's office has indicated that it may need to issue $9 billion - $11 billion in revenue anticipation warrants this June to retire its currently outstanding revenue anticipation notes and satisfy its financial obligations during the June 2003 fiscal year end. Investment Strategy For the six-month period ended March 31, 2003, the short-term municipal market experienced two distinct segments. Initially, short-term municipal yields moved higher as a result of unusually heavy supply in the short end of the yield curve. The State of California and the California Department of Water Resources both marketed multi-billion dollar issues that pushed overall short-term municipal yields to period highs by late October 2002. One-year note yields that began the period in the 1.45% range rose to the 1.75% area, while the average variable rate yield rose from 1.55% to 1.85%. However, from early November 2002 through period end, the increased uncertainty surrounding international events and strong asset inflows * Based on a constant investment throughout the period, with dividends compounded daily, and reflecting a net return to the investor after all expenses. 1 into the short end of the yield curve strengthened demand for these municipal securities. This higher demand lowered the yield on a one-year fixed coupon note to the 1.10% range, while the average variable rate yield fell to the 1.15% range by period end. We maintained the Fund's average portfolio maturity in a neutral range of 30 days - 50 days. This investment strategy was appropriate in light of growing global uncertainties. Additionally, the flat nature of the short-term yield curve offered little incentive to implement a more aggressive investment stance. Within the portfolio, fixed coupon securities with maturities predominately in the six-month - nine-month range remained an important diversification tool and provided an avenue to secure attractive yields through the first quarter of 2003. Two of our larger purchases in this sector were $120 million in State of California Revenue Anticipation Notes with a June 2003 maturity and $70 million in California Department of Water Resources bonds with a February 2003 maturity. During this time, average variable rate yields, which adjust on a daily or weekly basis, fell to a period low of .95% - 1.00% because of strong demand. The Fund's fixed coupon securities, which included municipal notes, puts and tax-exempt commercial paper, comprised approximately 30% of the Fund's assets during the period and performed especially well as variable rate yields moved lower. Finally, the Fund's portfolio strategy and asset allocation during the six-month period ended March 31, 2003 provided shareholders with a well-diversified portfolio of high credit quality securities and a stable net asset value. Looking forward, we will continue to closely monitor budget developments in California. We expect that county and local governments will be increasing the level of issuance during the upcoming summer note season as a result of an expected decrease in state assistance. This increase in issuance could possibly place significant upward pressure on California-specific short-term yields. In Conclusion We thank you for your continued support of CMA California Municipal Money Fund, and we look forward to serving your investment needs in the months and years ahead.

See Notes to Financial Statements. 12 CMA CALIFORNIA MUNICIPAL MONEY FUND NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- 1. Significant Accounting Policies: CMA California Municipal Money Fund (the "Fund") is part of CMA Multi-State Municipal Series Trust (the "Trust"). The Fund is registered under the Investment Company Act of 1940 as a non-diversified, open-end management investment company. The Fund's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- Investments are valued at amortized cost, which approximates market value. For the purpose of valuation, the maturity of a variable rate demand instrument is deemed to be the demand notice payment period. In the case of a floating rate instrument, the remaining maturity is the next coupon date on which the interest rate is to be adjusted. (b) Income taxes -- It is the Fund'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 income to its shareholders. Therefore, no Federal income tax provision is required. (c) Security transactions and investment income -- Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Interest income (including amortization of premium and discount) is recognized on the accrual basis. (d) Prepaid registration fees -- Prepaid registration fees are charged to expense as the related shares are issued. (e) Dividends and distributions to shareholders -- The Fund declares dividends daily and reinvests daily such dividends (net of non-resident alien tax withheld and backup withholding tax withheld) in additional fund shares at net asset value. Dividends are declared from the total of net investment income, excluding discounts earned other than original issue discounts. Net realized capital gains, if any, are normally distributed annually after deducting prior years' loss carryforward. The Fund may distribute capital gains more frequently than annually in order to maintain the Fund's net asset value at $1.00 per share. (f) Expenses -- Certain expenses have been allocated to the individual Funds in the Trust on a pro rata basis based upon the respective aggregate net asset value of each Fund included in the Trust. (g) Reclassification -- Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, the current year's permanent book/tax difference of $373,554 has been reclassified between paid-in capital in excess of par and accumulated net realized capital losses. This reclassification has no effect on net assets or net asset value per share. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee based upon the average daily value of the Fund's net assets, at the following annual rates: .50% of the first $500 million of average daily net assets; .425% of average 13 CMA CALIFORNIA MUNICIPAL MONEY FUND NOTES TO FINANCIAL STATEMENTS (CONCLUDED) - -------------------------------------------------------------------------------- daily net assets in excess of $500 million but not exceeding $1 billion, and ..375% of average daily net assets in excess of $1 billion.

These financial statements and the financial highlights are the responsibility of the Fund'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 auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and the financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 31, 2003, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 CMA California Municipal Money Fund as of March 31, 2003, 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 its 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.
