Economic Environment Arizona's economy is improving at a slow but steady pace thanks to the state's service and government sectors. Income growth has decelerated but is still above the national average, helping sustain growth in personal service and retail spending. Manufacturing remained the biggest drag on the state's economy during the past year. For example, in September 2002, industrial production dipped and the Arizona Business Index fell below 50 for the first time since December 2001. Currently, one of the biggest positives for Arizona is its concentration in defense-related companies. This should continue to benefit the state with ongoing domestic and international security-related concerns. Arizona is home to five major military bases that provide 50,000 jobs and have a $6 billion economic impact on the state. Arizona should also benefit from a recent bill passed by Congress that pushes pay hikes for all defense personnel and creates new positions for border and airport security. Arizona's tourism industry has remained weak with revenue per room down more than 9% for year-to-date August 2002. The area that was most adversely affected by the recession was the tourism industry in northern Arizona. Anchored by the Grand Canyon, visitation was down almost 40% compared to the same time last year and remained subdued all summer. Population growth in Arizona continues to be very impressive. As of July 2002, the state's population was over 5.4 million, up by 1.8 million or 49.3% from the 1990 census. This population increase, combined with low mortgage rates during the past few years, has helped the state's housing market remain solid. Going forward, resurging demand for semiconductors, coupled with increased demand for defense-related manufacturing, should benefit Arizona's economy. The state's financial operations have tightened considerably over the past year with continued stress projected into fiscal year 2004. Arizona has been experiencing the impact of the general economic slowdown on its revenues, particularly sales and income tax collections. Additionally, the state's high-technology sector has been contracting, resulting in declining income taxes and job growth. As a result, faced with an approximately $1 billion budget imbalance for fiscal year 2003, the state held two special sessions adjusting the fiscal year 2003 budget by a total of almost $1.2 billion. In April 2002, adjustments included $240 million in revenue bonds to replace pay-as-you-go funding for school construction, $230 million in budget reductions and $191 million in funding deferral. In November 2002, adjustments for additional budget reductions of $264 million were made, including $208 million on an ongoing basis. For fiscal year 2004, the state's estimated budget deficit is projected to be $1.2 billion or 15.8% of the state's budget. Strategies to reduce fiscal year 2004's budget deficit include across-the-board cuts, reduction of local aid and use of the state's rainy day fund. Consequently, the state's rainy day fund, which totaled $400 million in 2000, stood at only $47 million as of June 30, 2002. The state has not yet made a decision whether to securitize tobacco settlement revenues to help reduce their projected budget deficit in 2004. Because of these factors, Standard & Poor's changed the outlook on Arizona's credit rating from stable to negative in August. Investment Strategy At the beginning of the 12-month period ended March 31, 2003, we sought to maintain the * Based on a constant investment throughout the period, with dividends compounded daily, and reflecting a net return to the investor after all expenses. 1 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. 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 that 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 tremendous demand for short-term tax-exempt instruments. This was a result of the Federal Reserve Board's lowering of the Federal Funds rate by 50 basis points at the November 6, 2002 Federal Open Market Committee meeting and cash inflows that continued 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 rise in yields on variable rate product as tax time approaches. 2 In Conclusion We thank you for your support of CMA Arizona Municipal Money Fund, and we look forward to serving your investment needs in the months and years ahead.

See Notes to Financial Statements. 9 CMA ARIZONA MUNICIPAL MONEY FUND NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- 1. Significant Accounting Policies: CMA Arizona 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. 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 10 CMA ARIZONA MUNICIPAL MONEY FUND NOTES TO FINANCIAL STATEMENTS (CONCLUDED) - -------------------------------------------------------------------------------- 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 $4,214 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 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.
