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 MICHIGAN MUNICIPAL MONEY FUND MARCH 31, 2004 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager With interest rates holding at historic lows, we looked to purchase one-year fixed rate paper throughout the period, but used variable rate demand notes opportunistically for yield enhancement. How did the Fund perform during the period in light of the existing market conditions? For the 12-month period ended March 31, 2004, CMA Michigan Municipal Money Fund paid shareholders a net annualized yield of .42%.* As of March 31, 2004, the Fund's seven-day yield was .40%. Much of the fiscal year was characterized by an accommodative Federal Reserve Board, which was content to keep interest rates at historically low levels. 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 throughout the past 12 months. Describe conditions in the State of Michigan during the period. Michigan's economy continued to face considerable challenges during the 12-month period. Economic signals were hopeful in the first half of the year. For example, the state's manufacturing sector was beginning to stabilize and employment in every other industry showed signs of improvement. Nevertheless, the state's unemployment rate continued to rise, reaching 7.4% in August 2003, the highest level in the Midwest. Michigan's fiscal situation also remained weak. The long national economic downturn, along with previously implemented income tax cuts, resulted in a sharp decline in state revenues. In addition, Michigan's once-substantial budget reserve fund was exhausted after the remaining $145 million was used to balance the fiscal 2003 budget. The following year's $1.7 billion budget gap was closed largely through broad-based spending cuts, the use of Federal aid and smaller revenue enhancements. On December 30, 2003, Standard & Poor's, a leading bond rating agency, lowered the state's credit rating one notch from AAA to AA+. The downgrade reflected a substantial decline in Michigan's general fund balance, which initially was projected to be $360 million as of September 30, 2003, but ended with a shortfall of $569 million because of lower-than-expected tax collections. As we ended the period, the state continued to grapple with high unemployment, a sluggish housing market and weak household balance sheets. For example, the percentage of delinquent loans in Michigan was higher than in any other Midwestern state. In addition, despite low mortgage rates, home sales increased by less than 5% in 2003 and sales were actually down 10% in the first two months of 2004. The state is currently projected to end fiscal year 2004 with a general fund deficit of $888 million. * 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 MICHIGAN MUNICIPAL MONEY FUND MARCH 31, 2004 What changes were made to the portfolio during the period? As the fiscal year began, we were looking to increase the Fund's position in variable rate securities for liquidity purposes. These securities tend to have shorter maturities and, given the inverted yield curve at that time, shorter-maturity investments were offering higher yields than their longer-maturity counterparts. We also expected yields on variable rate products to spike because of redemptions related to tax time. The Fund benefited from this strategy, as variable rate demand notes offered an average yield of 1.25% versus 1.10% for one-year fixed rate paper. As summer approached, variable rate securities became less attractive as concerns about deflation and the expectation for additional interest rate cuts caused yields on shorter-maturity securities to drop. After the Federal Reserve Board's final interest rate cut in June 2003, we expected monetary policy would be on hold for some time. With that in mind, we were comfortable to increase the Fund's weighting in fixed rate securities, extending the portfolio's average maturity from 25 days to approximately 50 days by September 30, 2003. The final months of 2003 brought evidence of a recovering economy, but inflation remained modest and the job market continued to be sluggish. Under these circumstances, we felt that short-term interest rates would remain at current low levels well into 2004. Thus, despite Michigan's modest issuance, we continued to look for opportunities to invest in fixed rate paper and, during the fourth quarter of 2003, we added approximately $26.5 million worth of investments yielding an average of 1.15%. Although we continued to search for fixed rate paper in the new year, the flatness of the short-term tax-exempt yield curve offered little incentive to extend further out. As the period came to an end, we were looking to increase our weighting in variable rate paper -- again seeking to take advantage of higher yields typically available during tax season. How would you characterize the portfolio's position at the close of the period? The Fund ended the period in a slightly bearish stance given the lack of attractive investment opportunities over the past few months. We expect the Fund's increased weighting in variable rate demand notes as of March 31, 2004 will allow us to benefit from the traditional increase in yields associated with tax-related selling, at least in the upcoming quarter. Looking further ahead, we believe the Federal Reserve Board will likely keep monetary policy on hold well into 2004 to ensure a sustainable economic recovery. With that in mind, we will continue to look for opportunities to extend the portfolio's average maturity when prudent. Darrin J.

See Notes to Financial Statements. 12 CMA MICHIGAN MUNICIPAL MONEY FUND MARCH 31, 2004 Notes to Financial Statements 1. Significant Accounting Policies: CMA Michigan 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 fee -- 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 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. CMA MICHIGAN MUNICIPAL MONEY FUND MARCH 31, 2004 13 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (concluded) 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 $6,760 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. 3. Shares of Beneficial Interest: The number of shares sold, reinvested and redeemed during the years 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 ................... $1,456,641 $2,938,918 ------------------------------ Total distributions .................... $1,456,641 $2,938,918 ============================== As of March 31, 2004, there were no significant differences between the book and tax components of net assets. 5. Capital Loss Carryforward: On March 31, 2004, the Fund had a net capital loss carry-forward of $40,093, of which $23,497 expires in 2005, $6,574 expires in 2006, $5,068 expires in 2008 and $4,954 expires in 2009. This amount will be available to offset like amounts of any future taxable gains. 14 CMA MICHIGAN 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 Michigan 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 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 Michigan 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.
