However, these objectives cannot be achieved in all interest rate environments. To leverage, the Fund issues Preferred Shares, which pay dividends at prevailing short-term interest rates, and invests the proceeds in long-term municipal bonds. The interest earned on these investments is paid to Common Shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the per share net asset value of the Fund's Common Shares. However, in order to benefit Common Shareholders, the yield curve must be positively sloped; that is, short-term interest rates must be lower than long-term interest rates. At the same time, a period of generally declining interest rates will benefit Common Shareholders. If either of these conditions change, then the risks of leveraging will begin to outweigh the benefits. To illustrate these concepts, assume a fund's Common Share capitalization of $100 million and the issuance of Preferred Shares for an additional $50 million, creating a total value of $150 million available for investment in long-term municipal bonds. If prevailing short-term interest rates are approximately 3% and long-term interest rates are approximately 6%, the yield curve has a strongly positive slope. The fund pays dividends on the $50 million of Preferred Shares based on the lower short-term interest rates. At the same time, the fund's total portfolio of $150 million earns the income based on long-term interest rates. Of course, increases in short-term interest rates would reduce (and even eliminate) the dividends on the Common Shares. In this case, the dividends paid to Preferred Shareholders are significantly lower than the income earned on the fund's long-term investments, and therefore the Common Shareholders are the beneficiaries of the incremental yield. However, if short-term interest rates rise, narrowing the differential between short-term and long-term interest rates, the incremental yield pickup on the Common Shares will be reduced or eliminated completely. At the same time, the market value of the fund's Common Shares (that is, its price as listed on the New York Stock Exchange) may, as a result, decline. Furthermore, if long-term interest rates rise, the Common Shares' net asset value will reflect the full decline in the price of the portfolio's investments, since the value of the fund's Preferred Shares does not fluctuate. In addition to the decline in net asset value, the market value of the fund's Common Shares may also decline. As a part of its investment strategy, the Fund may invest in certain securities whose potential income return is inversely related to changes in a floating interest rate ("inverse floaters"). In general, income on inverse floaters will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Investments in inverse floaters may be characterized as derivative securities and may subject the Fund to the risks of reduced or eliminated interest payments and losses of invested principal. In addition, inverse floaters have the effect of providing investment leverage and, as a result, the market value of such securities will generally be more volatile than that of fixed-rate, tax-exempt securities. To the extent the Fund invests in inverse floaters, the market value of the Fund's portfolio and the net asset value of the Fund's shares may also be more volatile than if the Fund did not invest in these securities. Swap Agreements The Fund may also invest in swap agreements, which are over-the-counter contracts in which one party agrees to make periodic payments based on the change in market value of a specified bond, basket of bonds, or index in return for periodic payments based on a fixed or variable interest rate or the change in market value of a different bond, basket of bonds or index. Swap agreements may be used to obtain exposure to a bond or market without owning or taking physical custody of securities. MuniHoldings Florida Insured Fund, February 28, 2003 DEAR SHAREHOLDER For the six months ended February 28, 2003, the Common Shares of MuniHoldings Florida Insured Fund had a net annualized yield of 6.11%, based on a period-end share net asset value of $15.70 and $.476 per share income dividends. Over the same period, the total investment return on the Fund's Common Shares was +5.28%, based on a change in per share net asset value from $15.41 to $15.70, and assuming reinvestment of $.475 per share ordinary income dividends. For the six-month period ended February 28, 2003, the Fund's Preferred Shares had an average yield as follows: Series A, 1.03%; Series B, 1.19%; Series C, 1.11%; Series D, 1.23%; and Series E, 1.23%. The Municipal Market Environment During the six-month period ended February 28, 2003, long-term fixed income interest rates continued to move lower. 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 in September 2002. The dramatic decline in equity values during September also helped trigger 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 fell 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 the third quarter, gross domestic product growth was 4%, well above the second quarter 2002 rate of 1.3%. 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. However, over the past three months, softer equity prices and renewed investor concerns about U.S. military action against Iraq and nuclear tensions in North Korea again pushed bond prices higher. Reacting to disappointing holiday sales and corporate managements' attempts to scale back analysts' expectation of future earnings, the S&P 500 Index declined more than 8% during the last three months. Fearing a U.S./Iraq military confrontation in early 2003, investors again sought the safety of U.S. Treasury obligations. During February, U.S. Treasury bond yields declined more than 25 basis points to end the period at 4.67%. Over the last six months, U.S. Treasury bond yields fell more than 25 basis points. For the six-month period ended February 28, 2003, tax-exempt bond prices also continued to rise. 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, however, 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 the year. At February 28, 2003, long-term municipal bond yields, as measured by the Bond Buyer Revenue Bond Index, stood at 5.10%, a decline of approximately 15 basis points during the last six months. A number of factors combined to generate consistently strong demand for municipal bonds throughout the six-month period ended February 28, 2003. Declining U.S. equity markets supported continued positive demand for tax-exempt products as investors sought the relative security of fixed income issues. Also, with tax-exempt money market rates near 1%, the demand for longer maturity municipal issues has increased as investors have opted to buy longer maturity issues rather than remain in cash reserves. Additionally, investors renewed approximately $30 billion in January 2003 from bond maturities, coupon income and proceeds from early redemptions. However, these positive demand factors have not been totally 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. Declining U.S. equity markets and escalating geopolitical pressures have resulted in reduced economic activity and consumer confidence. Consequently, fixed income bond yields have continued to decline to recent historic lows and to levels that may not be supported by economic fundamentals alone. It is important to note that, despite all the negative factors impeding the growth of U.S. businesses, the U.S. economy still grew at an approximate 2.5% rate for all of 2002, twice that of 2001. Similar expansion is expected in early 2003. However, until both Iraqi and North Korean conflicts are resolved, any meaningful increase in interest rates is unlikely. Some analysts expect that, upon resolution of these conflicts, U.S. business conditions will quickly improve. Bond yields, especially U.S. Treasury securities, which have enjoyed a significant safe-haven benefit, are also expected to quickly rise. However, it is questionable to expect that even a quick, positive closure to these hostilities would restore business and investor confidence to the extent that U.S. economic growth would dramatically explode and foster associated, large-scale interest rate increases. The resumption of solid economic growth is likely to be a gradual process accompanied by equally graduated increases in bond yields. Moderate economic growth, within the content of negligible inflationary pressures, should not greatly endanger the positive fixed income environment tax-exempt products are currently experiencing. Specific to Florida, the state's General Fund budget proposal for the 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 classroom 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 year 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 2 & 3 MuniHoldings Florida Insured Fund, February 28, 2003 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 position in the coming year to perform well, given their prospective management and financial flexibility. Portfolio Strategy For the six months ended February 28, 2003, we maintained the Fund's neutral position, as we focused on reducing the volatility of the Fund. We continued to sell some of the Fund's 10-year - 15-year bonds and purchased larger-couponed bonds maturing in 20 years - 30 years. These longer maturities are expected to enhance the Fund's income stream and help preserve asset valuations during future periods of market volatility. During the period, new-issue supply was up approximately 40% compared to the same period a year ago. Despite the heavy supply, retail and institutional demand remained robust. This strong demand hindered us from fully implementing our desired strategy. The vast majority of new bond issuance has been structured as par bonds, which are more price sensitive and produce less income than desired premium coupon structured issues. 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. During the period, the Fund's borrowing costs remained in the 1% - 1.5% range, with interest rates presently below 1%. These very attractive funding levels, in combination with the steep tax-exempt yield curve, generated a significant income benefit to the Fund's Common Shareholders from the leveraging of the Preferred Shares. We do not anticipate any material reduction in the Fund's borrowing costs in 2003 as additional monetary policy easing by the Federal Reserve Board is not expected. We anticipate the Fund's short-term borrowing costs to remain in the 1% - 1.5% range for most of the year. However, should the spread between short-term and long-term interest rates narrow, the benefits of leverage will decline and, as a result, reduce the yield on the Fund's Common Shares. (For a more complete explanation of the benefits and risks of leveraging, see page 1 of this report to shareholders.) In Conclusion We appreciate your ongoing interest in MuniHoldings Florida Insured Fund, and we look forward to assisting you with your financial needs in the months and years ahead.

See Notes to Financial Statements. 14 & 15 MuniHoldings Florida Insured Fund, February 28, 2003 NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: MuniHoldings Florida Insured Fund, (the "Fund") is registered under the Investment Company Act of 1940 as a non-diversified, closed-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 will determine and make available for publication the net asset value of its Common Shares on a weekly basis. The Fund's Common Shares are listed on the New York Stock Exchange under the symbol MFL. 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 most recent bid price or yield equivalent as obtained by the Fund's pricing service from dealers that make markets in such 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). Securities 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 Fund, including valuations furnished by a pricing service retained by the Fund, which may utilize a matrix system for valuations. The procedures of the pricing service and its valuations are reviewed by the officers of the Fund under the general supervision of the Board of 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. o Options -- The Fund is authorized to write covered call options and purchase put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked to market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. o Forward interest rate swaps -- The Fund is authorized to enter into forward interest rate swaps for the purpose of hedging the interest rate risk on portfolio securities. In a forward interest rate swap, the Fund and the counterparty agree to pay or receive interest on a specified notional contract amount, commencing on a specified future effective date, unless terminated earlier. The value of the agreement is determined by quoted fair values received daily by the Fund from the counterparty. When the agreement is closed, the Fund records a realized gain or loss in an amount equal to the value of the agreement. (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 Fund amortizes all premiums and discounts on debt securities. (e) Dividends and distributions -- Dividends from net investment income are declared and paid monthly. Distribution of capital gains are recorded on the ex-dividend dates. 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 the six months ended February 28, 2003, the Fund reimbursed FAM $11,523 for certain accounting services. Certain officers and/or trustees of the Fund are officers and/or directors of FAM, PSI, and/or ML & Co. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the six months ended February 28, 2003 were $82,413,882 and $79,155,759, respectively.

(1,023,446) (1,660,765) ----------- ----------- Total ......................................... $ 1,354,991 $71,159,266 =========== =========== - ------------------------------------------------------------------------------- As of February 28, 2003, net unrealized appreciation for Federal income tax purposes aggregated $72,206,388, of which $72,325,100 related to appreciated securities and $118,712 related to depreciated securities. The aggregate cost of investments at February 28, 2003 for Federal income tax purposes was $876,092,973. 4. Share Transactions: The Fund is authorized to issue an unlimited number of shares of beneficial interest, including Preferred Shares, par value $.10 per share, all of which were initially classified as Common Shares. The Board of Trustees is authorized, however, to reclassify any unissued shares of beneficial interest without approval of holders of Common Shares. Common Shares Shares issued and outstanding for the six months ended February 28, 2003 and for the year ended August 31, 2002, remained constant. Preferred Shares Auction Market Preferred Shares ("AMPS") are redeemable Preferred Shares of the Fund, with a par value 16 & 17 MuniHoldings Florida Insured Fund, February 28, 2003 NOTES TO FINANCIAL STATEMENTS (concluded) of $.10 per share and a liquidation preference of $25,000 per share plus accrued and unpaid dividends, that entitle their holders to receive cash dividends at an annual rate that may vary for the successive dividend periods. The yields in effect at February 28, 2003 were as follows: Series A, 1.02%; Series B, 1.02%; Series C, 1.02%; Series D, 1.02% and Series E, 1.02%. Shares issued and outstanding for the six months ended February 28, 2003 and for the year ended August 31, 2002, remained constant. The Fund pays commissions to certain broker-dealers at the end of each auction at an annual rate ranging from .25% to .375%, calculated on the proceeds of each auction. For the six months ended February 28, 2003, Merrill Lynch, Pierce, Fenner & Smith Incorporated, an affiliate of FAM, earned $249,043 as commissions. 5. Capital Loss Carryforward: On August 31, 2002, the Fund had a net capital loss carryforward of $59,696,283, of which $7,768,611 expires in 2006, $25,529,487 expires in 2007, $9,834,324 expires in 2008 and $16,563,861 expires in 2009. This amount will be available to offset like amounts of any future taxable gains. 6. Subsequent Event: The Fund paid a tax-exempt income dividend to holders of Common Shares in the amount of $.080000 per share payable on March 28, 2003 to shareholders of record as of March 17, 2003. MANAGED DIVIDEND POLICY The Fund's dividend policy is to distribute all or a portion of its net investment income to its shareholders on a monthly basis. In order to provide shareholders with a more consistent yield to the current trading price of the Fund's Common Shares, the Fund may at times pay out less than the entire amount of net investment income earned in any particular month and may at times in any particular month pay out such accumulated but undistributed income in addition to net investment income earned in that month. As a result, the dividends paid by the Fund for any particular month may be more or less than the amount of net investment income earned by the Fund during such month. The Fund's current accumulated but undistributed net investment income, if any, is disclosed in the Statement of Net Assets, which comprises part of the financial information included in this report.

The Fund also seeks to offer shareholders the opportunity to own shares, the value of which is exempt from Florida intangible personal property tax. The Fund seeks to achieve its investment objective by investing primarily in a portfolio of long-term, investment-grade municipal obligations, the interest on which, in the opinion of bond counsel to the issuer, is exempt from Federal income taxes and which enables shares of the Fund to be exempt from Florida intangible personal property tax. This report, including the financial information herein, is transmitted to shareholders of MuniHoldings Florida Insured Fund for their information. It is not a prospectus. Past performance results shown in this report should not be considered a representation of future performance. The Fund has leveraged its Common Shares and intends to remain leveraged by issuing Preferred Shares to provide the Common Shareholders with a potentially higher rate of return. Leverage creates risks for Common Shareholders, including the likelihood of greater volatility of net asset value and market price of shares of the Common Shares, and the risk that fluctuations in the short-term dividend rates of the Preferred Shares may affect the yield to Common Shareholders.
