The year, which opened with geopolitical turmoil, unrelenting economic uncertainty and a dismal continuation of a three-year equity market slump, vigorously reversed course in the months that followed. As we entered 2004, the equity markets maintained their positive momentum from year-end 2003. For the six-month and 12-month periods ended January 31, 2004, the Standard & Poor's (S&P) 500 Index returned +15.23% and +34.57%, respectively. In the fixed income markets, investors willing to accept the greatest risk were rewarded the most. This trend held true in the municipal bond market as well, where high yield issues generally outperformed investment grade bonds. For the six-month and 12-month periods ended January 31, 2004, the Lehman Brothers Non-Investment Grade Index of municipal bonds posted respective returns of +9.99% and +15.33%. The major signposts indicate that we are seeing a shift from economic growth fueled primarily by fiscal and monetary stimulus to a broader-based, self-sustaining economic expansion. Gross domestic product growth, which peaked at an annualized rate of 8.2% in the third quarter of 2003, is estimated at a more sustainable 4% in the fourth quarter. That level of growth is expected to repeat itself in the first quarter of 2004. For its part, the Federal Reserve Board has reiterated its willingness to keep short-term interest rates at current low levels to ensure the economy's strength. Accompanying the increase in economic activity was an improvement in corporate earnings. By the end of January, 298 of the S&P 500 companies had reported their fourth-quarter results, and 67.4% of those exceeded expectations. In the meantime, the American consumer, who continued to spend despite the faltering economy, may get further incentive from another round of Federal tax refunds in 2004. At Merrill Lynch Investment Managers, we believe the events and efforts of 2003 leave us with a much stronger economy and recent optimism suggests 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. 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 MERRILL LYNCH FLORIDA MUNICIPAL BOND FUND JANUARY 31, 2004 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager Our strategy has been and continues to be focused on increasing the Fund's yield while protecting net asset value in what has been a volatile interest rate environment. Discuss the recent market environment relative to municipal bonds. Over the past six months, long-term fixed income interest rates generally declined as the U.S. economy gained strength. Gross domestic product growth expanded at an annualized rate of 8.2% in the third quarter of 2003, with fourth-quarter growth estimated at 4.0%. These figures were well above the 1.4% rate of growth registered in the first quarter of 2003. Improving economic conditions benefited equity markets, as the Standard & Poor's 500 Index, a widely recognized measure of U.S. stock market performance, returned +15.23% for the six months ended January 31, 2004. Despite the strong growth, the Federal Reserve Board seemed apt to leave short-term interest rates at their current low levels, citing subdued employment growth and the absence of material inflationary pressures. While short-term interest rates remained at historic lows, long-term interest rates generally declined over the past six months. At the end of January 2004, long-term U.S. Treasury bond yields stood at 4.96%, having dropped 40 basis points (.40%) from six months earlier. In the tax-exempt bond market, long-term revenue bond yields also fell 40 basis points to 5.02%, as measured by the Bond Buyer Revenue Bond Index. Both 30-year and 10-year Aaa-rated municipal issues -- the highest rated -- saw their yields decrease approximately 50 basis points during the six-month period ended January 31, 2004, as reported by Municipal Market Data. Although improving U.S. equity valuations took some attention away from fixed income markets, overall demand for tax-exempt products remained positive. With tax-exempt money market rates at or below 1% and low nominal municipal bond yields in general, many investors have moved increasingly further out on the municipal yield curve to generate the desired level of tax-exempt income. This gravitation toward longer maturities helped support the strong demand and performance exhibited by tax-exempt products during the period. The municipal bond market's performance also benefited from a notable improvement in supply/demand dynamics. In recent months, the pace of new municipal bond issuance has greatly declined. For the 12 months ended January 31, 2004, municipalities issued more than $375 billion in new securities, an increase of approximately 5% compared to last year's issuance. Clearly, municipalities viewed the historically low interest rates over the past year as an opportunity to finance existing infrastructure needs and to refinance outstanding, higher-coupon debt. Over the past six months, however, new issuance fell 11.5% compared to the same period a year earlier. The decline was even more pronounced in the last three months, with a decrease of more than 13% compared to the same three months last year. This decline in supply helped strengthen the municipal market's positive technical position and enhanced recent performance. New-issue supply is expected to remain manageable in early 2004 and should help support the tax-exempt bond market's position as an attractive fixed income investment alternative. Describe conditions in the State of Florida. Overall, conditions in Florida remained favorable. The state maintained solid credit ratings of Aa2 from Moody's, AA+ from Standard & Poor's and AA from Fitch. All three rating agencies held a stable outlook for Florida's finances. This was based on an improving and diverse economy, solid finances, moderate debt and a proactive government that responds to economic downturns quicker than other states. Florida's economy is bolstered by strong population growth, which is attributed to its attractive physical environment and favorable business climate. Population growth is one reason Florida's economy typically has performed better than the national economy. Although the growth in population has put a strain on services such as education, transportation and health care, it also has allowed the state to recover quickly from the recent sub par economic trends. Currently, the state's revenues are modestly higher than projected and expenditures remain under control due to strong fiscal oversight. The fiscal year 2004 budget was pressured by only modest revenue increases, but was brought into balance through tight expenditure controls, including outsourcing work and requiring local governments to pick up costs historically incurred by the state. To pay for these additional expenses, municipalities imposed increases to property taxes and/or local sales taxes through voter initiatives. Florida continues to maintain sound and solid fund balances with consistent General Fund operations. In addition, the 4 MERRILL LYNCH FLORIDA MUNICIPAL BOND FUND JANUARY 31, 2004 state has a working Capital Reserve Fund and a Budget Stabilization Fund in excess of $1.8 billion. Our strategy in purchasing Florida issues has been to favor insured general obligation bonds and their equivalents rather than uninsured bonds. We believe this is a prudent approach, as there is no meaningful yield offered in exchange for the additional risk associated with uninsured bonds. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended January 31, 2004, the Fund's Class A, Class B, Class C and Class I Shares had total returns of +5.73%, +5.51%, +5.46% and +5.78%, respectively. Results were generally in line with the +5.73% return of the unmanaged benchmark Lehman Brothers Municipal Bond Index for the same period. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 6 and 7 of this report to shareholders.) The Fund outperformed its comparable Lipper category of Florida Municipal Debt Funds, which had an average return of +4.94% for the six-month period ended January 31, 2004. (Funds in this Lipper category limit their investment to those securities exempt from taxation in the State of Florida.) What changes were made to the portfolio during the period? We made no significant changes to the portfolio or our investment strategy in the past six months. We maintained our focus on enhancing income provided to shareholders and seeking to mute the Fund's net asset value volatility. The most volatile part of the yield curve during the period continued to be the 10-year - 15-year sector. During periods of sustained strength in the bond market, we sought to reduce some of our holdings in this maturity range. With the proceeds from the sales, we looked to purchase premium-coupon bonds in the 20-year - 30-year maturity range whenever they became available. Our observations and research reveal that the longer end of the yield curve has held firm. As such, this is where we have found the greatest value. By taking advantage of the steep yield curve, we have successfully been able to enhance the Fund's yield while muting its net asset value volatility. How would you characterize the portfolio's position at the close of the period? In our view, the municipal market will continue to be volatile over the next few months. Should interest rates continue to decline, we intend to shift to a more defensive position to prepare the Fund to perform well when interest rates eventually head higher. As long as the municipal yield curve remains steep, we will continue to sell the intermediate part of the curve and use periods of volatility to structure higher-coupon bonds whenever they are attractively priced.

Current performance may be lower or higher than the performance data quoted. Refer to www.mlim.ml.com to obtain more current performance information. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gains distributions at net asset value on the payable date. 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. 18 MERRILL LYNCH FLORIDA MUNICIPAL BOND FUND JANUARY 31, 2004 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 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. 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 multiple classes of shares. Shares of Class A and Class I 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 A, Class B and Class C 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 are traded primarily in the over-the-counter 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 by the Fund's pricing service 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 closing prices as of the close of such exchanges. Options written or purchased are valued at the last sale price in the case of exchange-traded options. In the case of options traded in the over-the-counter market, valuation is the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued by quoted fair values received daily by the Fund from the counterparty. Short-term investments with a remaining maturity 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 Board of Trustees. (b) Derivative financial instruments -- The Fund may engage in various portfolio investment strategies both to increase the return of the Fund and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. 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. 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. MERRILL LYNCH FLORIDA MUNICIPAL BOND FUND JANUARY 31, 2004 19 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) (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 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.
