As they had in 2002, declining U.S. equity markets and escalating worldwide political tensions easily overshadowed the incipient U.S. economic recovery, allowing bond yields to fall to recent historical lows. Economic releases, such as national employment and purchasing manager surveys, were generally weak early in the period. Additionally, at its August 2002 meeting, the Federal Reserve Board indicated that concerns about future economic weakness outweighed those of rising inflation. This signaled that the Federal Reserve Board was more likely to continue to lower short-term interest rates to boost economic activity rather than to raise them to reduce inflationary pressures. These factors combined to generate a very favorable fixed income environment during August and September 2002. The dramatic decline in equity values in late August and September triggered a significant fixed income rally as investors sought the safe-haven status of U.S. Treasury issues. By the end of September, U.S. Treasury bond yields had fallen to 4.65%. Bolstered by an unexpected decline in the national unemployment rate to 5.6% in early October, U.S. equity markets staged a strong rally throughout much of the month. The Standard & Poor's 500 (S&P 500) Index rose over 8% for October, triggered by stronger-than-expected earnings reports from a large number of companies, such as General Electric Company, International Business Machines Corporation and Microsoft Corporation. As they have throughout most of the period, bond prices traded in an inverse relationship to equity prices. Consequently, as stocks rallied, bond yields rose in October, despite generally weak economic releases. During October, the U.S. housing sector remained quite robust, but retail sales and industrial production slowed. Fixed income bond yields remained under pressure in November as U.S. equity markets continued to strengthen. During November, the S&P 500 Index rose an additional 5.5%. Equity prices were supported by further signs of U.S. economic recovery, especially improving labor market activity. By the end of November, third quarter gross domestic product growth was 4%. Financial conditions were also strengthened by a larger-than-expected reduction in short-term interest rates by the Federal Reserve Board in early November. The Federal Funds target rate was lowered 50 basis points (.50%) to 1.25%, its lowest level since the 1960s. Recent action by the Federal Reserve Board was largely viewed as being taken to bolster the sputtering U.S. economic recovery. Rebounding U.S. equity markets and the prospects for a more substantial U.S. economic recovery pushed long-term U.S. Treasury yield levels to 5.10% by late November. In December 2002 and January 2003, softer equity prices and renewed investor concerns about potential military action against Iraq and nuclear tensions in North Korea again pushed bond prices higher. The S&P 500 Index declined more than 5% in December on disappointing earnings reports and anticipated weak holiday retail sales. During January, the S&P 500 Index declined an additional 2.5% as businesses tried to scale back analysts' expectations of future earnings. In early 2003, investors again sought the safety of U.S. Treasury securities. U.S. Treasury bond yields declined more than 25 basis points in December and January to end the period at approximately 4.85%. Over the last six months, U.S. Treasury bond yields fell more than 45 basis points. For the six-month period ended January 31, 2003, tax-exempt bond prices also generally rose. In recent months, municipal bond yields have declined in response to the positive fixed income environment engendered by falling equity valuations. Price advances in tax-exempt issues have not been able to keep pace with U.S. Treasury bond price improvement as municipal bonds cannot offer foreign investors the safe-haven status U.S. Treasury obligations enjoy in periods of economic and political instability. Additionally, tax-exempt bond issuance increased dramatically in the last half of 2002, removing some of the positive technical support the municipal bond market enjoyed earlier in 2002. At the end of January 2003, long-term municipal bond yields, as measured by the Bond Buyer Revenue Bond Index, stood at 5.34%, a decline of approximately 15 basis points during the last six months. Investor demand for tax-exempt products remained positive throughout the period. In addition to the 1 Merrill Lynch Florida Municipal Bond Fund January 31, 2003 approximately $75 billion investors received from June to August 2002 from bond maturities, coupon income and proceeds from early redemptions, investors also received approximately $30 billion from these sources in January 2003. The Investment Company Institute reported that in 2002 municipal bond funds net cash flows were very positive at more than $16 billion, an increase of over 40% compared to 2001. However, these positive demand factors have not been able to offset the increase in tax-exempt new-issue supply that has resulted in the underperformance seen in recent months. This price underperformance served to make municipal bonds a particularly attractive purchase relative to their taxable counterparts. Throughout most of the yield curve, municipal bonds have been available for purchase at yields near or exceeding those of comparable U.S. Treasury issues. Compared to their recent historical averages of 82% - 88% of U.S. Treasury yields, municipal bond yield ratios in their current 95% - 105% range are likely to prove attractive to long-term investors. Continued uncertainty regarding the pace of the current U.S. economic recovery as well as the resolution of the U.N./Iraq confrontation are likely to keep interest rates near their present levels for the immediate future. Equity market declines over the past three years have helped push interest rates lower than economic fundamentals alone would support. When U.S. business conditions improve and equity markets stabilize, any associated interest rate increases should not be extreme. Inflationary pressures are negligible and any move by the Federal Reserve Board to raise short-term interest rates is unlikely before late 2003. As equity valuations are likely to only gradually improve, the U.S. economic recovery is also likely to be a moderate process. This suggests that the pace of any interest rate increases will also be gradual. As the municipal bond market's strong technical position can be expected to remain supportive in the coming months, future tax-exempt interest rate increases should be more restrained than their taxable counterparts. Specific to Florida, the state's General Fund budget proposal for fiscal year 2003-2004 is $53.9 billion, a 7% increase from the prior year. This budget will attempt to close a $2 billion fiscal year 2004 operating shortfall. It includes currently passed referendums for smaller class sizes, enrolling four-year olds as pre-kindergartners and a high-speed rail line. Florida is projected to end fiscal year 2002-2003 with an operating surplus of $140 million and a Rainy Day Fund at $960 million, a sharp contrast to most other states. With the implementation of the constitutional amendments, spending will increase faster than revenues and will force the state to borrow. In fiscal 2004, $3 billion is earmarked for schools. However, this is just part of an estimated $4 billion - $27 billion cost for education during the next eight years. With this increase in spending in the current fiscal year, other programs will be reduced and/or eliminated to pick up the expense. Some proposed cuts include $200 million from transportation, $111 million from universities and $51 million from juvenile crime prevention. Additional expenditure savings will be derived by outsourcing state agency functions such as payroll and benefits administration, totaling another $200 million. These reductions, along with an increase in the corporate tax structure, the inclusion of video lottery terminals at racetracks and improving sales tax collections are estimated to generate more than $1 billion. Proposed expenditure reductions and revenue increases, along with a sizeable Rainy Day Fund, will enable the state to operate without increasing other taxes. However, the state balanced its budget by burdening local governments and universities by asking the voters to increase local sales taxes and/or increase tuition to meet local operations. Even though the state is being pressured by a weak national economy, we believe it is in a position in the coming year to perform well given its prospective management and financial flexibility. Portfolio Strategy For the six months ended January 31, 2003, we maintained the Fund's neutral position, as we continued to focus on reducing the volatility of the Fund. During the period, U.S. equity and fixed income markets were quite volatile. The Federal Reserve Board lowered short-term interest rates in November 2002 and the municipal bond yield curve remained very steep. We continued to sell some of the Fund's 10-year - 15-year bonds and with the proceeds purchased larger-couponed bonds maturing in 20 years - 30 years. These longer-dated maturities are expected to enhance the Fund's income stream and help preserve asset valuations during future periods of market volatility. 2 Merrill Lynch Florida Municipal Bond Fund January 31, 2003 During the period, new-issue supply was up approximately 27% compared to the same period a year ago. Despite the heavy supply, retail and institutional demand has remained quite strong. This limited us from fully implementing our desired strategy of continuing to sell some of the Fund's 10-year - 15-year bonds and purchase larger-couponed bonds maturing in 20 years - 30 years as they become available. Going forward, the municipal bond curve is expected to remain quite steep. Therefore, we look to maintain the Fund's neutral position and will remain fully invested in an effort to enhance shareholder income. In Conclusion We appreciate your ongoing interest in Merrill Lynch Florida Municipal Bond Fund, and we look forward to serving your investment needs in the months and years to come.

Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of account maintenance, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

See Notes to Financial Statements. 15 Merrill Lynch Florida Municipal Bond Fund January 31, 2003 NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: Merrill Lynch Florida Municipal Bond Fund (the "Fund") is part of Merrill Lynch 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. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim period presented. All such adjustments are of a normal, recurring nature. The Fund offers four classes of shares under the Merrill Lynch Select Pricing(SM) System. Shares of Class A and Class D are sold with a front-end sales charge. Shares of Class B and Class C may be subject to a contingent deferred sales charge. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class B, Class C and Class D Shares bear certain expenses related to the account maintenance of such shares, and Class B and Class C Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its account maintenance and distribution expenditures. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses on investments are allocated daily to each class based on its related net assets. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- Municipal bonds and other portfolio securities in which the Fund invests are traded primarily in the over-the-counter municipal bond and money markets and are valued at the last available bid price in the over-the-counter market or on the basis of yield equivalents as obtained from one or more dealers that make markets in the securities. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their settlement prices as of the close of such exchanges. Short-term investments with remaining maturities of sixty days or less are valued at amortized cost, which approximates market value. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust, including valuations furnished by a pricing service retained by the Trust, which may utilize a matrix system for valuations. The procedures of the pricing service and its valuations are reviewed by the officers of the Trust under the general supervision of the Trustees. (b) Derivative financial instruments -- The Fund may engage in various portfolio investment strategies to increase or decrease the level of risk to which the Fund is exposed more quickly and efficiently than transactions in other types of instruments. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Fund may purchase or sell financial futures contracts and options on such futures contracts for the purpose of hedging the market risk on existing securities or the intended purchase of securities. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. (c) 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. (d) 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. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. The 16 Merrill Lynch Florida Municipal Bond Fund January 31, 2003 Fund amortizes all premiums and discounts on debt securities. (e) Dividends and distributions -- Dividends from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (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. The Fund has also entered into a Distribution Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc. 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: .55% of the Fund's average daily net assets not exceeding $500 million; .525% of average daily net assets in excess of $500 million but not exceeding $1 billion; and .50% of average daily net assets in excess of $1 billion. For the six months ended January 31, 2003, FAM reimbursed the Fund in the amount of $2,879. Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor ongoing account maintenance and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows: - -------------------------------------------------------------------------------- Account Distribution Maintenance Fee Fee - -------------------------------------------------------------------------------- Class B .......................... .25% .25% Class C .......................... .25% .35% Class D .......................... .10% -- - -------------------------------------------------------------------------------- Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., also provides account maintenance and distribution services to the Fund. The ongoing account maintenance fee compensates the Distributor and MLPF&S for providing account maintenance services to Class B, Class C and Class D shareholders. The ongoing distribution fee compensates the Distributor and MLPF&S for providing shareholder and distribution-related services to Class B and Class C shareholders. For the six months ended January 31, 2003, FAMD earned underwriting discounts and MLPF&S earned dealer concessions on sales of the Fund's Class A and Class D Shares as follows: - -------------------------------------------------------------------------------- FAMD MLPF&S - -------------------------------------------------------------------------------- Class A .......................... $ 41 $ 498 Class D .......................... $1,453 $15,544 - -------------------------------------------------------------------------------- For the six months ended January 31, 2003, MLPF&S received contingent deferred sales charges of $34,498 and $1,349 relating to transactions in Class B and Class C Shares, respectively. Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. For the six months ended January 31, 2003, the Fund reimbursed FAM $1,702 for certain accounting services.
