Economic Environment During the year ended March 31, 2003, Michigan's economy continued to perform poorly. Consequently, the sluggish economy took its toll on population growth, which has decelerated steadily over the past four years. In 2002, the .4% increase in population was below the regional average and less than half of the U.S. average. If this trend continues, it may put the state at risk of a labor shortage once the economy heats up again as was the case in the mid 1990s. After stabilizing early in the year, the state's employment base contracted into year end. Job losses also accelerated as expansion in the service industry was not enough to offset losses in other sectors. Despite the weak labor market, the housing market remained solid with home construction rebounding and sales surging by a 22% annualized rate in the fourth quarter of 2002. During the past year, Michigan auto manufacturers have continued to deal with lower demand by ratcheting up sales incentives. Moreover, in January 2003 an increase in inventory caused manufacturers to slow assembly lines and lay off workers. However, for the long term, Michigan's economy should continue to benefit from large capital investments expected by auto manufacturers. For example, DaimlerChrysler created a joint venture with Mitsubishi Motors and Hyundai Motor Company to build an engine plant in the state. General Motors Corporation and Ford Motor Company also have plans to invest heavily in Michigan facilities going forward. Although the state has endured a rough year, consumer conditions have deteriorated less than the national average. As a result, the share of households filing bankruptcy remains below the national average and delinquency rates on most types of loans are falling. The state's finances continued to deteriorate during the past year as sluggish economic activity resulted in lagging tax revenues. According to the latest revenue forecast, Michigan is currently facing an expected $410 million shortfall in its fiscal 2003 budget. Strategies under consideration to fill this budget gap include layoffs, reduction in local funding, restructuring of debt and use of the state's rainy day fund. At more than $1 billion just over two years ago, the rainy day fund is expected to end fiscal 2003 at $31 million. In March 2003, Governor Granholm rolled out a $38.6 billion budget proposal for 2004 that uses bond refinancing and a host of spending cuts to offset an anticipated $1.7 billion shortfall. Additionally, for the first time in several years, the state is expecting to issue up to $1 billion in short-term cash-flow notes this spring. The short-term debt, which would be repaid by September 30, 2003, will be used to bridge the cash shortfall and lack of reserves expected during this period. Lastly, although the time frame has not been identified, the state is contemplating the securitization of tobacco settlement revenues to help reduce their expected budget deficit. Investment Strategy At the beginning of the 12-month period ended March 31, 2003, we sought to maintain the Fund's relatively bearish stance. This was because of our expectation of a rise in interest rates as reflected by the Federal Reserve Board's change in bias from that of weakness to neutral at the March 19, 2002 Federal Open Market Committee meeting. In addition, this position allowed the Fund to take advantage of the anticipated rise in yields on variable rate product caused by outflows during tax time. As tax season began, a smaller amount of income tax related redemptions caused variable rate product to underperform compared to previously purchased fixed rate securities. Consequently, although we allowed the Fund to trend to a more bearish position, we continued to benefit from the more aggressive stance attained early in the first quarter of 2002. As the period progressed, economic data began to reveal that growth for the second quarter of 2002 was slowing from that of the first quarter. * Based on a constant investment throughout the period, with dividends compounded daily, and reflecting a net return to the investor after all expenses. 1 Furthermore, U.S. equity markets were suffering from a confidence crisis caused by accounting scandals and corporate malfeasance. For example, the Dow Jones Industrial Average, which began the period at 10,362, declined to 7,992 by the end of March 2003. As a result of these factors, we looked to move to a more neutral position given our opinion that the Federal Reserve Board would not tighten monetary policy in the coming months. A majority of our extension took place in April and May 2002 as we tried to lock in higher yields than were expected going forward. This strategy benefited the Fund as yields on tax-exempt securities maturing in one year declined almost 70 basis points (.70%) by the end of June 2002. As summer ended, continued weakness in capital expenditures and another possible military confrontation with Iraq caused the U.S. economy to weaken. In fact, at its August 13, 2002 Federal Open Market Committee meeting, the Federal Reserve Board changed its outlook from neutral back to that of weakness. As the second half of the period began, we looked to maintain the Fund's current stance because it was our opinion that the significant short-term issuance from the State of California would cause general market variable rate product to outperform fixed rate securities through year end. Our strategy benefited the Fund as yields on variable rate product averaged 1.65%, while yields on fixed rate product averaged 1.45% through mid-November. Nevertheless, from mid-November 2002 to early March 2003, yields on variable rate securities declined significantly because of the tremendous demand for short-term tax-exempt instruments. This was caused by both the Federal Reserve Board lowering the Federal Funds rate by 50 basis points at the November 6, 2002 Federal Open Market Committee meeting and continued cash inflows through February 2003. Since we anticipated that the Federal Reserve Board would keep monetary policy on hold for the near term, we continued to look for attractive opportunities to moderately extend our average portfolio maturity during this time. However, this proved to be difficult given a flat short-term tax-exempt yield curve and lack of state-specific fixed rate issuance. Our strategy allowed the Fund to provide a total return that was above average relative to its peer group for the one-year period ended March 31, 2003 according to iMoneyNet, Inc. As the period ended, we planned to maintain our current position, given the significant rally in the note market and the expected spike in yields on variable rate product as tax time approaches. In Conclusion We thank you for your support of CMA Michigan Municipal Money Fund, and we look forward to serving your investment needs in the months and years ahead. Sincerely, /s/ Terry K.

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 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 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 $36,921 have been reclassified between paid-in capital in excess of par and accumulated net investment loss. 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 9 CMA MICHIGAN 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. 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, 2003, the Fund reimbursed FAM $7,226 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, 2003 and March 31, 2002 was as follows: - -------------------------------------------------------------------------------- 3/31/2003 3/31/2002 - -------------------------------------------------------------------------------- Distributions paid from: Tax-exempt income ............................... $2,938,918 $6,752,576 ---------- ---------- Total distributions ...................... $2,938,918 $6,752,576 ========== ========== - -------------------------------------------------------------------------------- As of March 31, 2003, there were no significant differences between the book and tax components of net assets. 5. Capital Loss Carryforward: On March 31, 2003, the Fund had a net capital loss carryforward of $49,128, of which $32,532 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. 10 CMA MICHIGAN MUNICIPAL MONEY FUND INDEPENDENT AUDITORS' REPORT - -------------------------------------------------------------------------------- To the Shareholders and Board of Trustees of CMA Michigan Municipal Money Fund 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 as of March 31, 2003, 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 financial highlights for each of the five years in the period then ended.
