The high yield market, as measured by the Credit Suisse First Boston High Yield Index, provided a six-month return of +8.65% and a 12-month return of +22.86% as of March 31, 2004. By comparison, the Lehman Brothers Aggregate Bond Index returned +2.98% and +5.40% and the Lehman Brothers Municipal Bond Index returned +3.12% and +5.86% for the six-month and 12-month periods ended March 31, 2004, respectively. As of March month-end, the Federal Reserve Board maintained its accommodative policy stance, pledging "patience" in raising interest rates. As a result, short-term interest rates remained at historic lows and kept the short end of the yield curve relatively flat, making it increasingly difficult to find attractive income opportunities. Market watchers continue to monitor the economic data and Federal Reserve Board language for indications of interest rate direction. Having said that, if the economy continues to grow at its recent pace, many believe it is just a matter of time before interest rates move upward. Equity markets, in the meantime, continued to provide attractive returns. For the six-month and 12-month periods ended March 31, 2004, the Standard & Poor's 500 Index returned +14.08% and +35.12%, respectively. Much of the boost came from improving economic conditions throughout the past year. Significant fiscal and monetary stimulus, including the low interest rates and tax cuts, has opened the door to consumer spending, capital spending, increases in exports and long-awaited job growth. As expected, these positive developments have led the way to improvements in corporate earnings -- a positive for stock markets. The events and efforts of the past year leave us with a much stronger economy today. With all of this in mind, we believe it is time for investors to consider what can go right in 2004. We encourage you to revisit your portfolio and your asset allocation strategy to ensure you are well positioned to take advantage of the opportunities that lie ahead. Your financial advisor can help you develop a strategy designed to perform through all types of market and economic cycles. We thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the months and years ahead. Sincerely, /s/ Terry K. Glenn Terry K. Glenn President and Trustee CMA CALIFORNIA MUNICIPAL MONEY FUND MARCH 31, 2004 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager We extended the Fund's average maturity based on our belief that short-term borrowing rates were likely to remain stable at least through the first quarter of 2004. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended March 31, 2004, CMA California Municipal Money Fund paid shareholders a net annualized yield of .49%.* As of March 31, 2004, the Fund's seven-day yield was .49%. Our principal investment strategy was to maintain the Fund's average portfolio maturity at or above its peer group average. We implemented this strategy based on our belief that short-term borrowing rates would remain stable, at least through the first quarter of 2004. We believed that fixed-coupon securities such as municipal notes and puts, which have effective maturities up to 13 months, would outperform variable rate demand products during this period given the relative stability of short-term interest rates. This, in fact, was the case as the average yield on the one-year note, as measured by the Bond Buyer One-Year Note Index, was 1.08% for the 12-month period ended March 31, 2004. The average seven-day variable rate yield, as measured by the BMA Municipal Swap Index, was 1.00% during the same period. Our purchase of $460 million in California tax-exempt municipal notes and puts through December 2003 was the key driver in implementing our overall investment strategy. The purchases, which provided yields ranging from .92% to 1.58%, benefited Fund performance while also affording us excellent asset diversification and solid credit quality. For its part, the Federal Reserve Board remained accommodative throughout the year. The last in a series of interest rate cuts came in June 2003, as the Federal Reserve Board looked to stimulate economic growth and ward off the potential for deflation. Although economic growth began to accelerate later in the year, concerns over weak job growth persisted in the market. Investors tried to anticipate when the Federal Reserve Board would restore interest rates to more neutral levels. The constant interest rate analysis translated into widespread volatility, which created opportunities in the fixed income markets. Describe conditions in the State of California during the period. It was a turbulent 12 months for California. The state's political situation was especially noteworthy. In October 2003, voters emphatically recalled Democratic Governor Gray Davis and replaced him with Republican Governor Arnold Schwarzenegger. Prior to that special election, the uncertainty over the vote temporarily paralyzed state budget negotiations. The stalemate led major rating agencies to downgrade California's credit rating to historically low levels. Ongoing fiscal challenges forced the state to issue a record amount of short-term municipal debt over the past 12 months. This issuance, which included $11 billion worth of revenue anticipation warrants (RAWs) and $1.9 billion in revenue anticipation notes (RANs) -- both backed by financial institutions -- allowed the state to meet its financial obligations through June 2004. During the period, the Fund was an active buyer of the RAWs, which performed very well and provided yields ranging from 1.07% to 1.58%. * Based on a constant investment throughout the period, with dividends compounded daily, and reflecting a net return to the investor after all expenses. 4 CMA CALIFORNIA MUNICIPAL MONEY FUND MARCH 31, 2004 During the final month of the period, California's short-term financial outlook brightened considerably. Voters approved $15 billion worth of bonds to finance the state's deficit and retire the outstanding RAWs and RANs once they come due in June. The approval also will provide legislators much-needed time to address California's continued budget imbalance. What changes were made to the portfolio during the period? As mentioned earlier, the primary change made during the 12-month period was our decision to reallocate a portion of the Fund's assets out of variable rate demand products and into fixed-coupon securities. The goal was to extend the portfolio's average maturity. Given that short-term interest rates were at historic lows and seemingly in a holding pattern, longer-dated fixed rate securities presented the more attractive investment opportunity in our view. Our expectations about the yield advantages of fixed rate notes were met, as indicated by the figures referenced earlier. We accomplished this reallocation of assets primarily through the purchase of municipal notes and puts. During the period, we increased the Fund's weighting in notes and puts by 10%, bringing our allocation to 31% of net assets as of March 31, 2004. We decreased the Fund's weighting in variable rate securities by a similar percentage. How would you characterize the portfolio's position at the close of the period? We believe the Fund is well positioned for the current interest rate environment. We will continue to monitor the tone and actions of the Federal Reserve Board to determine the potential for an increase in short-term interest rates. We plan to maintain the current flexibility in the portfolio's structure and react as needed to any changes in market conditions. One likely area of focus in the months ahead will be on our municipal note holdings. We plan to seek attractive opportunities to reinvest a significant portion of the Fund's note positions maturing before September 30, 2004. As a result of the successful passage of California's deficit-financing referendum, we expect a substantial reduction this year in the state's tax-exempt note issuance. The referendum will make it unnecessary for California to issue RAWs, which traditionally are used to bridge the state's short-term financing needs over a fiscal year-end. Nevertheless, we do expect California counties and municipalities to issue annual short-term financing notes in June, although the large reduction in state issuance is likely to place downward pressure on short-term note yields. As always, we will continue to monitor developments in the State of California and gauge their potential impact on Fund holdings. Steven T.

See Notes to Financial Statements. 14 CMA CALIFORNIA MUNICIPAL MONEY FUND MARCH 31, 2004 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 amended, 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. 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 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. Pursuant to the Distribution and Shareholder Servicing Plan in compliance with Rule 12b-1 under the Investment Company Act of 1940, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S") receives a distribution fee from the Fund at the end of each month at the annual rate of .125% of average daily net assets of the Fund. The distribution fee is to compensate MLPF&S financial advisors and other directly involved branch office personnel for selling shares of the Fund and for providing direct personal services to shareholders. The distribution fee is not compensation for the administrative and operational services rendered to the Fund by MLPF&S in processing share orders and administering shareholder accounts. Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. For the year ended March 31, 2004, the Fund reimbursed FAM $52,231 for certain accounting services. Certain officers and/or trustees of the Fund are officers and/or directors of FAM, PSI, FDS, and/or ML & Co. CMA CALIFORNIA MUNICIPAL MONEY FUND MARCH 31, 2004 15 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (concluded) 3. Shares of Beneficial Interest: The number of shares sold, reinvested and redeemed during the periods corresponds to the amounts included in the Statements of Changes in Net Assets for net proceeds from sale of shares, value of shares reinvested and cost of shares redeemed, respectively, since shares are recorded at $1.00 per share. 4. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended March 31, 2004 and March 31, 2003 was as follows: - -------------------------------------------------------------------------------- 3/31/2004 3/31/2003 - -------------------------------------------------------------------------------- Distributions paid from: Tax-exempt income .................... $13,030,838 $22,521,346 ------------------------------- Total distributions .................... $13,030,838 $22,521,346 =============================== As of March 31, 2004, there were no significant differences between the book and tax components of net assets. 5. Capital Loss Carryforward: At March 31, 2004, the Fund had a net capital loss carryforward of $118,826, all of which expires in 2009. This amount will be available to offset like amounts of any future taxable gains. 16 CMA CALIFORNIA MUNICIPAL MONEY FUND MARCH 31, 2004 Independent Auditors' Report To the Shareholders and Board of Trustees of CMA Multi-State Municipal Series Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of CMA California Municipal Money Fund of CMA Multi-State Municipal Series Trust (the "Trust") as of March 31, 2004, and the related statement of operations for the year then ended, the statements of changes in 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. 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 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 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, 2004, by correspondence with the custodian. 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 of CMA Multi-State Municipal Series Trust as of March 31, 2004, 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.

Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for the project as a whole. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting.
