CMA Pennsylvania Municipal Money Fund of CMA Multi-State Municipal Series Trust Box 9011 Princeton, NJ 08543-9011 Printed on post-consumer recycled paper To Our Shareholders: For the year ended March 31, 2003, CMA Pennsylvania Municipal Money Fund paid shareholders a net annualized yield of .83%.* As of March 31, 2003, the Fund's 7-day yield was .64%. Economic Environment During the year ended March 31, 2003, Pennsylvania's economy continued to struggle as the result of a global recession. Moreover, slower economic activity reduced corporate and personal spending, while a severe decline in the stock market virtually eliminated capital gains. Consequently, personal bankruptcies continued to accelerate through the fall and although Pennsylvania's incidence of bankruptcy is below the national average, the gap did narrow over the past year. This deterioration in credit quality is particularly alarming given that Pennsylvania's unemployment rate is currently at a cyclical high. Job losses have been broad based with only construction and government registering steady gains. For example, housing construction enjoyed an extended season this year as strong permit issuance continued late into the fall. Manufacturing, which continues to bear the brunt of the slower economy, has affected various parts of the commonwealth to varying degrees. In more diverse metro areas such as Pittsburgh and Philadelphia, the recession has had a smaller impact on employment than has been the case historically. Consequently, employment was more adversely affected in the more rural areas because their economies are still heavily reliant on manufacturing. *Based on a constant investment throughout the period, with dividends compounded daily, and reflecting a net return to the investor after all expenses. The commonwealth's finances remained strained during the past year because of the sluggish global economy. Fiscal 2003 year-to-date revenues through December 2002 indicated a $96 million shortfall from budget, and the commonwealth is currently projecting a $433 million gap for the fiscal year. Strategies to fill the gap include the implementation of a spending freeze and use of the commonwealth's Rainy Day Fund. The Rainy Day Fund, which totaled over $1 billion a few years ago, will end 2003 with no remaining funds. For fiscal year 2004, the governor's office is projecting a budget deficit ranging from $500 million to as much as $2 billion. The commonwealth has not disclosed if it is contemplating the securitization of tobacco revenues to reduce the expected deficit. Despite these economic trends, the commonwealth's practice of keeping budget growth to a minimum and revenue assumption realistic in the 1990s has helped prepare for this economic slowdown. However, if the economic slowdown is protracted, Pennsylvania will be faced with difficult choices in balancing budgetary needs compared to available resources. Per-capita wealth levels and the commonwealth's state tax-supported debt ratios remain close to national averages, with the latter showing an improving trend in recent years relative to other states. For the near future, cautious fiscal management practices are expected to be maintained and should accommodate a trend of slower economic growth. Going forward, Pennsylvania will likely see further job losses in the near term. While manufacturing could mount a rebound in 2003 if business revives, the bulk of Pennsylvania's job growth would most likely come from its service producing industries. The governor has signaled the possibility of a tax increase and a $20 million stimulus package that is directed to benefit the Pennsylvania business sector, which has struggled with the lack of investment nationally. In the long term, the commonwealth's poor demographic trends and a relatively low concentration of high-growth industries outside of the main two metropolitan areas will limit the potential for growth. 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. 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 Pennsylvania Municipal Money Fund, and we look forward to serving your investment needs in the months and years ahead. Sincerely, (Terry K.

See Notes to Financial Statements. CMA PENNSYLVANIA MUNICIPAL MONEY FUND NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: CMA Pennsylvania 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 $11,097 have 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 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 PENNSYLVANIA MUNICIPAL MONEY FUND 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, 2003, the Fund reimbursed FAM $11,739 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 $ 4,931,376 $ 10,743,926 ------------ ------------ Total distributions $ 4,931,376 $ 10,743,926 ============ ============ 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 $81,856, of which $22,380 expires in 2006, $3,815 expires in 2007, $20,995 expires in 2008, $33,951 expires in 2009 and $715 expires in 2010. This amount will be available to offset like amounts of any future taxable gains. CMA PENNSYLVANIA MUNICIPAL MONEY FUND INDEPENDENT AUDITORS' REPORT To the Shareholders and Board of Trustees of CMA Pennsylvania 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 Pennsylvania 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 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 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 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 Pennsylvania 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. Deloitte & Touche LLP Princeton, New Jersey May 8, 2003 CMA PENNSYLVANIA MUNICIPAL MONEY FUND IMPORTANT TAX INFORMATION (UNAUDITED) All of the net investment income distributions paid by CMA Pennsylvania Municipal Money Fund of CMA Multi-State Municipal Series Trust during its taxable year ended March 31, 2003 qualify as tax-exempt interest dividends for Federal income tax purposes.
