For the six- and 12-month periods ended February 28, 2006, most major market indexes landed in positive territory: Total Returns as of February 28, 2006 6-month 12-month ============================================================================================ U.S. equities (Standard & Poor's 500 Index) + 5.93% + 8.40% -------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) +10.24 +16.59 -------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) +15.14 +17.41 -------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers Aggregate Bond Index) - 0.11 + 2.74 -------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 0.99 + 3.87 -------------------------------------------------------------------------------------------- High yield bonds (Credit Suisse High Yield Index) + 1.89 + 3.27 -------------------------------------------------------------------------------------------- The Federal Reserve Board (the Fed) increased interest rates 200 basis points (2.00%) over the past 12 months, bringing the target federal funds rate to 4.5%. Notably, Ben Bernanke replaced Alan Greenspan as Fed chairman in January, a month after the central bank removed the critical word "measured" from the description of its rate-hiking program. Still, most observers expect at least one more interest rate hike before the Fed pauses in its tightening campaign. U.S. economic growth, which came in at 4.1% in the third quarter of 2005, fell to 1.6% in the fourth quarter. Growth is expected to reaccelerate in the first quarter of 2006, although the economy is likely to feel some pressure in the quarters ahead as the consumer sector seems to be softening. Capital spending by businesses, however, appears relatively strong. Overall corporate health, including strong company balance sheets, helped prompt robust dividend-distribution, share-buyback and merger-and-acquisition activity in 2005, a trend that has continued in 2006. This, as well as reasonably good company earnings and low core inflation, has been supportive of U.S. stocks despite the headwinds of rising interest rates and high energy prices. Many international equity markets have fared even better, thanks in part to higher economic growth rates and low inflation. In the U.S. bond market, short-term interest rates continued to move higher as longer-term interest rates advanced more moderately. After flattening dramatically in 2005, the Treasury curve recently has been toying with bouts of inversion, whereby short-term yields have surpassed long-term yields. At period-end, the six-month Treasury bill offered the highest yield on the curve at 4.74%. Amid the uncertainty inherent in the financial markets, we encourage you to review your goals periodically with your financial advisor and to make portfolio changes, as needed. For timely "food for thought" for investors, we also invite you to visit Shareholder magazine at www.mlim.ml.com/shareholdermagazine. As always, we thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to continuing to serve your investment needs. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. President and Director/Trustee SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 3 A Discussion With Your Funds' Portfolio Managers We primarily targeted the longer end of the municipal yield curve, which remained steep compared to the shorter end and provided opportunities for enhanced yield. Describe the recent market environment relative to municipal bonds. Over the past six months, long-term bond yields generally rose as their prices, which move in the opposite direction, declined. Investors appeared to disregard signs of slowing economic growth, reflected in gross domestic product growth of just 1.6% in the fourth quarter of 2005, and instead focused on potential inflationary pressures and continued short-term interest rate increases by the Federal Reserve Board (the Fed). In addition to inflationary fears sparked by elevated commodity prices, national hourly wage levels rose recently. This led some economic analysts to suggest that recent declines in the national unemployment rate will result in escalating wage inflation. The resurgent inflationary fears helped push bond yields higher over the past six months. For its part, the Fed has continued to raise short-term interest rates at each of its meetings during the period, bringing the federal funds rate to 4.5%. Given little expectation that the Fed's monetary tightening cycle will end in early 2006, the yield curve continued to flatten with shorter interest rates increasing more than longer ones. At the end of February 2006, 30-year U.S. Treasury bond yields had risen 25 basis points (.25%) to 4.51%, while 10-year Treasury yields rose 53 basis points to 4.55% and two-year Treasury yields rose 85 basis points to 4.69%. The result was an inverted Treasury yield curve. Notably, the municipal yield curve has maintained a positive slope. According to Municipal Market Data, AAA-rated tax-exempt bonds maturing in 30 years saw their yields increase eight basis points to 4.30%, while yields on AAA-rated issues maturing in 10 years increased 25 basis points to end the period at 3.75%. The tax-exempt market's positive technical position has allowed municipal bond prices to decline less than those of taxable bonds. Supporting the recent outperformance of the municipal bond market has been a dramatic slowdown in the issuance of new long-term tax-exempt bonds. In 2005, more than $408 billion in new long-term tax-exempt bonds was underwritten, representing a new annual record and an increase of over 13% compared to 2004. For the six-month period ended February 28, 2006, $172 billion in long-term municipal bonds was issued, a decline of 1.5% compared to the same period a year ago. More recently, new-issue volume has declined at an even faster rate. In the past three months, $76 billion in new long-term tax-exempt bonds was marketed, a decline of 16% compared to the same three months a year ago. The record level of new issuance in 2005 was largely triggered by a 47% increase in refunding activity as issuers took advantage of historically low bond yields and a flattening yield curve to refinance outstanding higher-couponed debt. So far in 2006, refunding issuance has declined more than 55% relative to the first two months of 2005. It remains to be seen if this decline is the beginning of a sustained trend toward a significant decline in refunding issuance. This is important, as analysts' estimates for new-issue supply for 2006, currently in the $340 billion - $370 billion range, are largely dependant on modest declines in refunding activity. Should the current trend continue, new-issue supply projections for this year could be adjusted lower. Investor demand for municipal product has remained strong. As reported by the Investment Company Institute (ICI), for all of 2005, long-term municipal bond funds received net new monies of $5.04 billion. This represented a sharp reversal from the $3.67 billion outflow seen in 2004. January 2006 data from ICI indicates that tax-exempt mutual funds have continued to experience positive cash flows, receiving over $2 billion for the month, more than twice the net new monies received in January 2005. Looking ahead, the fundamentals for the tax-exempt bond market appear favorable, and continued positive cash flows are anticipated. Given their attractive yields relative to comparable U.S. Treasury bonds, and the prospects for reduced issuance in 2006, we believe municipal bonds could enjoy solid results in the coming months. MuniHoldings Florida Insured Fund Describe conditions in the State of Florida. Florida's economy has outperformed that of both the nation and other southern states, and appears likely to continue this trend in the foreseeable future. The state's mix of solid demographics and increasing job growth among diversified industries is expected to continue to encourage migration into the state. Although national economic trends have put pressure on the state, we believe Florida is well positioned given its record of proactive management and financial flexibility. The state's enacted fiscal year 2005 - 2006 budget is $64.7 billion, an increase of 12% from the prior year. The budget 4 SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 reflects a combination of spending constraints, with spending below anticipated personal income growth, and increased revenue growth. Of the increased revenue, not all is expected to be permanent, as some stems primarily from the reconstruction and replacement of property destroyed by hurricanes and, therefore, is not recurring. Fiscal discipline has afforded the state the opportunity to provide tax relief in the form of tax-free shopping days, reduced sales tax on equipment, tax credits and a phase out of the intangible tax. Three areas of the budget account for 93% of the total expenditures -- education at 52%, health and human services at 26% and public safety at 15%. Revenues for the first four months of the fiscal year were $602 million, 14% higher than the same period in the prior fiscal year. How did the Fund perform during the period? For the six-month period ended February 28, 2006, the Common Shares of MuniHoldings Florida Insured Fund had net annualized yields of 5.89% and 5.91%, based on a period-end per share net asset value of $14.90 and a per share market price of $14.85, respectively, and $.435 per share income dividends. Over the same period, the total investment return on the Fund's Common Shares was +.24%, based on a change in per share net asset value from $15.32 to $14.90, and assuming reinvestment of all distributions. The Fund's total return, based on net asset value, lagged the +1.18% average return of the Lipper Florida Municipal Debt Funds category for the six-month period. (Funds in this Lipper category limit their investment to those securities exempt from taxation in the State of Florida.) For the most part, performance was impacted as the yield curve flattened and short and intermediate maturities underperformed. We had exposure to these sectors through bonds that had been prerefunded -- thereby transforming several of our longer-dated issues into intermediate-maturity issues -- and higher-coupon bonds priced to a short call. Despite their underperformance on a total return basis, these bonds were acquired in a higher interest rate environment and, as such, contribute meaningfully to the Fund's yield. This supports our long-term commitment to providing shareholders with an attractive level of income and allowed the Fund to maintain an above-average yield compared to its peers. To a lesser extent, the Fund's total return performance was affected by its conservative investment parameters. This prohibited us from investing in non-investment grade issues, which outperformed the high-grade market as credit spreads narrowed during the period. For a description of the Fund's total investment return based on a change in the per share market value of the Fund's Common Shares (as measured by the trading price of the Fund's shares on the New York Stock Exchange), and assuming reinvestment of dividends, please refer to the Financial Highlights section of this report. As a closed-end fund, the Fund's shares may trade in the secondary market at a premium or discount to the Fund's net asset value. As a result, total investment returns based on changes in the market value of the Fund's Common Shares can vary significantly from total investment returns based on changes in the Fund's net asset value. What changes were made to the portfolio during the period? We did not alter our strategy or make meaningful changes to the portfolio's composition during the six-month period. We continued to focus on increasing the income provided to shareholders and muting the Fund's net asset value volatility. To that end, we remained fully invested throughout the period in order to enhance yield. In making new purchases, we generally focused on premium-coupon bonds in the 20-year - 25-year maturity range whenever they became available. We observed the greatest value in this area, meaning we were able to capture most of the yield available on the curve without taking on the additional risk of extending into the 30-year range. Notably, we did begin to see some value in the 15-year area of the curve and continue to explore opportunities there. Issuance of Florida municipal bonds increased approximately 5% during the period compared to the same six months a year ago. As has been the case for some time, few new issues met our desired investment characteristics. Much of the supply came in the first three months of the period in the form of refinancings, and the majority of the new issues offered relatively short maturities and yields below 5%. We were not inclined to give up bonds booked in the portfolio at higher yields in order to take advantage of the new-issue calendar. For the six-month period ended February 28, 2006, the Fund's Auction Market Preferred Shares (AMPS) had average yields as follows: Series A, 2.71%; Series B, 2.81%; Series C, 2.85%; Series D, 2.71%; and Series E, 2.71%. At this point in the Fed's monetary tightening cycle, interest rate increases are having an impact on the Fund's borrowing costs. The Fed raised the short-term interest rate target 100 basis points during the six-month period. Nevertheless, we are still able to borrow at a lower rate than where we invest, and this has continued to generate an income benefit to the holders of Common Shares. Of course, should the spread between short-term and long-term interest rates narrow, the benefits of leveraging will decline and, as a result, reduce the yield on the Fund's Common Shares. At the end of the period, the Fund's leverage amount, due to AMPS, was 39.33% of total SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 5 A Discussion With Your Funds' Portfolio Managers ( concluded) net assets, before the deduction of Preferred Shares. (For a more complete explanation of the benefits and risks of leveraging, see page 8 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? We would characterize the Fund's position as fairly neutral in terms of interest rate risk. Currently, we favor bonds with 20-year - 25-year maturities and will also look to increase exposure to 15-year maturities. In the current low-yield environment, we are targeting bonds with 5% coupons, but will look for an increase in long-term rates as an opportunity to pursue higher-coupon bonds (5.25% and above) in the 20-year - 30-year maturity range. We are awaiting that back-up in interest rates, which would present an opportunity to sell some of the prerefunded bonds in the portfolio and purchase some longer-dated issues without giving up a great deal of yield. We expect the U.S. equity and bond markets to remain volatile as investors continue to anticipate and react to economic data and Fed actions. Many believe the Fed is nearing the end of its rate-hiking campaign. However, the central bank has indicated that it will become more "data dependent" in determining monetary policy, which leaves room for interpretation. Against this backdrop, we will continue to maintain a fully invested portfolio and intend to use periods of volatility to pursue higher-coupon bonds whenever they are attractively priced. MuniHoldings New York Insured Fund, Inc. Describe conditions in the State of New York. In December, credit-rating agency Moody's upgraded New York's rating to Aa3, the state's highest rating from Moody's since 1975. Standard and Poor's and Fitch maintained ratings of AA and AA-, respectively, and all three agencies assign a stable outlook to the state's ratings. The New York economy continues to improve and revenue collections are increasing. State tax collections remain largely dependant on the performance of the financial sector, but tax receipts for fiscal year 2005 (ended March 31, 2005) were 15% above the prior fiscal year. Due to surging tax collections, particularly income taxes, the fiscal year 2005 operating surplus totaled $1.2 billion. The fiscal year 2006 budget calls for $105 billion in spending and forecasts a 5% increase in tax receipts for the fiscal year (which began April 1, 2005). Aided by this revenue growth, the enacted budget includes most of the governor's original proposals for closing an estimated $4 billion deficit. However, this does not factor in a lawsuit won by the Campaign for Fiscal Equity that could add up to $2 billion in annual state education spending. Crafting balanced budgets beyond fiscal year 2006 will present a challenge given political resistance to additional tax hikes and cuts in popular programs, as well as pressure from local governments for pension and Medicaid relief, and new education spending. Governor Pataki proposed a $111 billion budget for fiscal year 2007 (which begins April 1, 2006) that includes an estimated $840 million in tax cuts during the year and suggested that an anticipated $2 billion surplus from the current 2006 fiscal year be applied toward out-year gaps. The legislature has not yet approved the 2007 budget, which still does not include any money for compliance with the court order on school funding. Current employment numbers show a 1% increase from the prior year. New York ranks fifth-highest among all states in per capita income. Economic growth is disproportionately stronger in downstate New York, while the upstate economy remains lackluster. How did the Fund perform during the period? For the six-month period ended February 28, 2006, the Common Stock of MuniHoldings New York Insured Fund, Inc. had net annualized yields of 5.92% and 5.96%, based on a period-end per share net asset value of $15.12 and a per share market price of $15.02, respectively, and $.444 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +.32%, based on a change in per share net asset value from $15.54 to $15.12, and assuming reinvestment of all distributions. The Fund's total return, based on net asset value, lagged the +.83% average return of the Lipper New York Insured Municipal Debt Funds category for the six-month period. (Funds in this Lipper category invest primarily in securities exempt from taxation in New York and insured as to timely payment.) Detracting from the Fund's total return performance was our exposure to prerefunded bonds and those with short call dates. While we've taken steps to reduce exposure to these shorter-term issues, we have been careful to retain some that have relatively high acquisition yields and, therefore, provide a meaningful income benefit to the portfolio. In fact, the Fund has been able to maintain an above-average distribution rate because of its yield advantage versus its New York insured peers. Contributing to Fund performance during the period were our positions in longer-dated bonds, which outperformed short and intermediate maturities as the yield curve 6 SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 flattened. The portfolio's housing bonds and AMT issues, which tend to offer additional yield, also performed well as investors continued to seek out higher levels of income in the low interest rate environment. Similarly, uninsured, higher-yielding issues, in which the portfolio may invest up to 20% of its net assets, also performed quite well due to a general tightening in credit spreads. For a description of the Fund's total investment return based on a change in the per share market value of the Fund's Common Stock (as measured by the trading price of the Fund's shares on the New York Stock Exchange), and assuming reinvestment of dividends, please refer to the Financial Highlights section of this report. As a closed-end fund, the Fund's shares may trade in the secondary market at a premium or discount to the Fund's net asset value. As a result, total investment returns based on changes in the market value of the Fund's Common Stock can vary significantly from total investment returns based on changes in the Fund's net asset value. What changes were made to the portfolio during the period? Throughout the period, we focused primarily on extending the average portfolio maturity by lightening our exposure to shorter-dated bonds and adding exposure to longer-dated issues. We have been particularly focused on trimming short-duration bonds of the high-coupon, short-call structure. Specifically, this has included bonds that are either prerefunded or have a call date within three years or less. These bonds are priced with a premium and, as the call date approaches, the bonds lose value at an accelerating rate. The downside of selling some of these bonds is that they either have a relatively high acquisition yield, having been bought in a higher rate environment, or are of a lower-quality, higher-yielding nature. Thus, we are trying to balance our desire to maintain an attractive yield with our goal of enhancing the portfolio's total return potential. We added longer-dated bonds to the mix as the new-issue market presented opportunities. This was somewhat challenging as the New York municipal market continued to be characterized by relatively low supply and new issues tended to come with shorter maturities and lower yields than we would prefer. One notable addition was bonds issued for the rehabilitation and expansion of the Jacob Javitz Convention Center. Those bonds we purchased had 35-year maturities. This not only assisted our goal of increasing the portfolio's average maturity, but also contributed to our efforts to enhance the Fund's diversification. To that end, we also added marginally to the portfolio's uninsured basket, which is capped at an allowable limit of 20% of net assets. We continue to seek opportunities within this sector, as it tends to offer good total return potential as well as additional yield. Within the New York insured municipal market, a well-defined trading range provided us with opportunities to execute relative value trades, thereby improving on security structures and book yields. For the six-month period ended February 28, 2006, the Fund's Auction Market Preferred Stock (AMPS) had average yields as follows: Series A, 2.55%; Series B, 2.49%; Series C, 2.63%; Series D, 2.72%; and Series E, 2.45%. At this point in the Fed's monetary tightening cycle, interest rate increases are having an impact on the Fund's borrowing costs. The Fed raised the short-term interest rate target 100 basis points during the six-month period. Nevertheless, we are still able to borrow at a lower rate than where we invest, and this has continued to generate an income benefit to the holders of Common Stock. Of course, should the spread between short-term and long-term interest rates narrow, the benefits of leveraging will decline and, as a result, reduce the yield on the Fund's Common Stock. At the end of the period, the Fund's leverage amount, due to AMPS, was 40.25% of total net assets, before the deduction of Preferred Stock. (For a more complete explanation of the benefits and risks of leveraging, see page 8 of this report to shareholders.) How would you characterize the portfolio's position at the close of the period? In terms of duration (that is, sensitivity to interest rate risk), the Fund ended the period neutral to slightly long relative to its New York insured peers. The Fed appears relatively close to the end of its measured monetary tightening campaign, with the consensus currently factoring in two more interest rate hikes by mid-year. When the Fed does signal its end, we would expect to see a strong rally in the intermediate part of the curve and a more moderate rally in the long end. Based on this scenario, we are targeting the intermediate to long maturity range, essentially 20 years - 30 years. We expect new municipal supply to remain fairly muted, creating a positive technical environment that should allow municipal bonds to outperform Treasuries in the months ahead. We continue to look for opportunities to diversify the Fund while also seeking to balance yield and total return potential in the portfolio. Robert D. Sneeden Vice President and Portfolio Manager MuniHoldings Florida Insured Fund Timothy T. Browse, CFA Vice President and Portfolio Manager MuniHoldings New York Insured Fund, Inc. March 9, 2006 SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 7 The Benefits and Risks of Leveraging The Funds utilize leveraging to seek to enhance the yield and net asset value of their Common Shares or Common Stock. However, these objectives cannot be achieved in all interest rate environments. To leverage, the Funds issue Preferred Shares or Stock, which pay dividends at prevailing short-term interest rates, and invest the proceeds in long-term municipal bonds. The interest earned on these investments, net of dividends to Preferred Shares or Stock, is paid to Common Shareholders or Common Stock 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 or Stock. However, in order to benefit Common Shareholders or Common Stock 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 or Common Stock 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 Shares or Stock capitalization of $100 million and the issuance of Preferred Shares or Stock 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 or Stock 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. In this case, the dividends paid to Preferred Shareholders or Preferred Stock shareholders are significantly lower than the income earned on the fund's long-term investments, and therefore the Common Shareholders or Common Stock 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 or Stock will be reduced or eliminated completely. At the same time, the market value on the fund's Common Shares or Stock (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' or Stock's 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 or Stock does not fluctuate. In addition to the decline in net asset value, the market value of the fund's Common Shares or Stock may also decline. As a part of their investment strategy, the Funds 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 Funds 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 Funds invest in inverse floaters, the market value of each Fund's portfolio and the net asset value of each Fund's shares may also be more volatile than if the Funds did not invest in these securities. As of February 28, 2006, the percentages of MuniHoldings Florida Insured Fund's and MuniHoldings New York Insured Fund, Inc.'s total net assets invested in inverse floaters were 4.88% and 7.60%, respectively, before the deduction of Preferred Shares or Stock. 8 SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 Portfolio Information Quality Profiles as of February 28, 2006 MuniHoldings Florida Insured Fund Percent of Total By S&P/Moody's Rating Investments -------------------------------------------------------------------------------- AAA/Aaa ..................................................... 95.9% AA/Aa ....................................................... 0.5 A/A ......................................................... 2.5 BBB/Baa ..................................................... 0.6 Other* ...................................................... 0.5 -------------------------------------------------------------------------------- * Includes portfolio holdings in short-term investments and variable rate demand notes.

Swap Agreements The Funds may 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 or reduce exposure to a bond or market without owning or taking physical custody of securities. Swap agreements involve the risk that the party with whom each Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement. Dividend Policy The Funds' dividend policy is to distribute all or a portion of their net investment income to their shareholders on a monthly basis. In order to provide shareholders with a more stable level of dividend distributions, the Funds 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 Funds for any particular month may be more or less than the amount of net investment income earned by the Funds during such month. The Funds' 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 these reports.

(the "Funds" or individually as the "Fund") are registered under the Investment Company Act of 1940, as amended, as non-diversified, closed-end management investment companies. The Funds' financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to present a fair statement of the results for the interim period. All such adjustments are of a normal, recurring nature. The Funds determine and make available for publication the net asset value of their Common Stock/Shares on a daily basis. The Funds' Common Stock/Shares are listed on the New York Stock Exchange under the symbols MFL and MHN, respectively. The following is a summary of significant accounting policies followed by the Funds. (a) Valuation of investments -- Municipal bonds are traded primarily in the over-the-counter ("OTC") markets and are valued at the last available bid price in the OTC market or on the basis of values as obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer-supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of the Funds under the general direction of the Board of Directors/Trustees. Such valuations and procedures are reviewed periodically by the Board of Directors/Trustees of the Funds. 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 OTC market, valuation is the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Funds from a pricing service. Short-term investments with a remaining maturity of 60 days or less are valued at amortized cost which approximates market value, under which method the investment is valued at cost and any premium or discount is amortized on a straight line basis to maturity. Investments in open-end investment companies are valued at their net asset value each business day. Securities and other 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 Directors/Trustees of the Funds. (b) Derivative financial instruments -- Each 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 -- Each 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 Funds 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 -- Each Fund may write covered call options and purchase call and 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 -- Each Fund may enter into forward interest rate swaps. In a forward interest rate swap, the Fund and the counterparty agree to make periodic net payments on a specified notional contract amount, commencing on a specified future effective date, unless terminated earlier. When the agreement is closed, 26 SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 Notes to Financial Statements (continued) the Fund records a realized gain or loss in an amount equal to the value of the agreement. (c) Income taxes -- It is each 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 Funds amortize all premiums and discounts on debt securities. (e) Dividends and distributions -- Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. 2. Investment Advisory Agreement and Transactions with Affiliates: Each 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 each Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, each Fund pays a monthly fee at an annual rate of .55% of the Fund's average weekly net assets, including proceeds from the issuance of Preferred Stock/Shares.

(the "Investment Adviser") or other Merrill Lynch affiliates is as a director of each Fund and as a trustee or director of certain other funds advised by the Investment Adviser or its affiliates. The Chairman of the Boards is also an independent director. New director nominees are chosen as nominees by a Nominating Committee comprised of independent directors. All independent directors also are members of each Board's Audit Committee and the independent directors meet in executive session at each in-person Board meeting. The Board and the Audit Committee meet in person for at least two days each quarter and conduct other in-person and telephone meetings throughout the year, some of which are formal board meetings, and some of which are informational meetings. The independent counsel to the independent directors attends all in-person Board and Audit Committee meetings and other meetings at the independent directors' request. Investment Advisory Agreements -- Matters Considered by the Board Every year, each Board considers approval of each Fund's investment advisory agreement (the "Investment Advisory Agreement"). Each Board assesses the nature, scope and quality of the services provided to each Fund by the personnel of the Investment Adviser and its affiliates, including administrative services, shareholder services, oversight of fund accounting, marketing services and assistance in meeting legal and regulatory requirements. Each Board also receives and assesses information regarding the services provided to the Fund by certain unaffiliated service providers. At various times throughout the year, each Board also considers a range of information in connection with its oversight of the services provided by the Investment Adviser and its affiliates. Among the matters considered are: (a) fees (in addition to management fees) paid to the Investment Adviser and its affiliates by each Fund; (b) Fund operating expenses paid to third parties; (c) the resources devoted to and compliance reports relating to each Fund's investment objective, policies and restrictions, and its compliance with its Code of Ethics and the Investment Adviser's compliance policies and procedures; and (d) the nature, cost and character of non-investment management services provided by the Investment Adviser and its affiliates. Each Board believes that the Investment Adviser is one of the most experienced global asset management firms and considers the overall services provided by the Investment Adviser to be of high quality. Each Board also believes that the Investment Adviser is financially sound and well managed and notes that the Investment Adviser is affiliated with one of America's largest financial firms. Each Board works closely with the Investment Adviser in overseeing the Investment Adviser's efforts to achieve good performance. As part of this effort, each Board discusses portfolio manager effectiveness and, when performance is not satisfactory, discusses with the Investment Adviser taking steps such as changing investment personnel. Annual Consideration of Approvals by the Board of Directors In the period prior to the Board meeting to consider renewal of the Investment Advisory Agreement, each Board requests and receives materials specifically relating to the Fund's Investment Advisory Agreement. These materials are prepared separately for each Fund, and include (a) information compiled by Lipper Inc. ("Lipper") on the fees and expenses, investment performance and leverage of the Fund as compared to a comparable group of funds as classified by Lipper; (b) information comparing the Fund's market price with its net asset value per share; (c) a discussion by the Fund's portfolio management team of investment strategies used by the Fund during its most recent fiscal year; (d) information on the profitability to the Investment Adviser and its affiliates of the Investment Advisory Agreement and other relationships with the Fund; (e) information provided by the Investment Adviser concerning investment advisory fees charged to other clients such as other closed-end insured leveraged funds for Florida and New York; and (f) services related to the valuation and pricing of Fund portfolio holdings, the Fund's portfolio turnover statistics, and direct and indirect benefits to the Investment Adviser and its affiliates from their relationship with the Fund. The Board did not identify any particular information as controlling, and each member of the Board may have attributed different weights to the various items considered. Certain Specific Renewal Data In connection with the most recent renewal of each Fund's Investment Advisory Agreement in February, 2006, the independent directors' and Board's review included the following: Investment Adviser's Services and Fund Performance -- Each Board reviewed the nature, extent and quality of services provided by the Investment Adviser, including the investment advisory services and the resulting performance SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 29 Disclosure of Investment Advisory Agreement (concluded) of each Fund. The Boards focused primarily on the Investment Adviser's investment advisory services and each Fund's investment performance, having concluded that the other services provided to each Fund by the Investment Adviser were satisfactory. Each Board compared Fund performance -- both including and excluding the effects of each Fund's fees and expenses -- to the performance of a comparable group of funds. While each Board reviews performance data quarterly, consistent with the Investment Adviser's investment goals, each Board attaches primary importance to performance over relatively long periods of time, typically three to five years. Relative to closed-end leveraged Florida municipal debt funds deemed comparable by the Investment Adviser, the Board noted that for the period ended November 30, 2005, MuniHoldings Florida Insured Fund's performance for the one-year period ranked sixth of seven funds, and for the three-year period ranked fifth of seven funds. For the five-year period, the Fund ranked first in a group of four funds. The Board also reviewed the Fund's performance based on annualized yields and noted that the Fund ranked first of seven funds for the past three years ended November 30, 2005, and first of four funds for the prior two years. The Board reviewed the Fund's investment objectives and strategies. The Board discussed with senior management of the Investment Adviser responsible for investment operations and the senior management of the Investment Adviser's municipal investing group the strategies being used to achieve the stated objectives. Among other things, the Board considered the size, education and experience of the Investment Adviser's investment staff, its use of technology, and the Investment Adviser's approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also reviewed the Investment Adviser's compensation policies and practices with respect to the Fund's portfolio manager. The Board also considered the experience of the Fund's portfolio manager and noted that Mr. Sneeden has over 10 years of experience investing in municipal securities. The Board concluded that the Fund's performance supported the continuation of the Investment Advisory Agreement. Relative to closed-end leveraged New York insured municipal debt funds, deemed comparable by the Investment Adviser, the Board noted that MuniHoldings New York Insured Fund's performance for the one- and three-year periods ranked in the fifth quintile, and in the fourth quintile for the five-year period. The Board also noted the Fund's performance based on annualized yields and noted that the Fund ranked in the first or second quintile for the four years ended November 30, 2005. The Board reviewed the Fund's investment objectives and strategies. The Board discussed with senior management of the Investment Adviser responsible for investment operations and the senior management of the Investment Adviser's municipal investing group the strategies being used to achieve the stated objectives. Among other things, the Board considered the size, education and experience of the Investment Adviser's investment staff, its use of technology, and the Investment Adviser's approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also reviewed the Investment Adviser's compensation policies and practices with respect to the Funds' portfolio manager. The Board also considered the experience of the Funds' portfolio manager and noted that Mr. Browse has over five years of experience investing in municipal securities. The Board concluded that the Fund's performance supported the continuation of the Investment Advisory Agreement. Management Fees and Other Expenses -- Each Board reviews the Fund's contractual management fee rate and actual management fee rate as a percentage of total assets at common asset levels -- the actual rate includes advisory and administrative service fees and the effects of any fee waivers -- compared to the other funds considered comparable by Lipper. It also compares the Fund's total expenses to those of other, comparable funds of the Investment Adviser. The Board noted that investment advisory fees charged to each of the Funds was slightly more than the fees charged to other retail closed-end Florida and New York insured funds of the Investment Adviser. With respect to MuniHoldings Florida Insured Fund, the Board noted that that the contractual management fee rate and total expense ratio were equal to the median fees charged by comparable funds, as determined by Lipper, while the actual management fees were higher than the median fees. With respect to MuniHoldings New York Insured Fund, Inc., the Board noted that the contractual management fee rate was equal to the median fees charged by comparable funds, as determined by Lipper, while the actual management fee rate and actual total expense ratio were higher than the median fees charged by such comparable funds. Each Board concluded that the Fund's management fee and fee rate and overall expense ratio (taking into account the fee waiver agreement applicable to each fund) are reasonable compared to those of other comparable funds. Profitability -- Each Board considered the cost of the services provided to the Fund by the Investment Adviser, and the Investment Adviser's and its affiliates' profits relating to the 30 SEMI-ANNUAL REPORTS FEBRUARY 28, 2006 management of the Fund and the MLIM/FAM-advised funds. As part of its analysis, each Board reviewed the Investment Adviser's methodology in allocating its costs to the management of the Fund and concluded that there was a reasonable basis for the allocation. The Boards also considered federal court decisions discussing an investment adviser's profitability and profitability levels considered to be reasonable in those decisions. Each Board concluded that the Investment Adviser's profits are acceptable in relation to the nature and quality of services provided and given the level of fees and expenses overall. Economies of Scale -- Each Board considered the extent to which economies of scale might be realized as the assets of a Fund increase and whether there should be changes in the management fee rate or structure in order to enable the Fund to participate in these economies of scale. Each Board considered economies of scale to the extent applicable to each Fund's closed-end structure and determined that each Fund appropriately benefits from any economies of scale and no changes were currently necessary. Conclusion After the independent directors deliberated in executive session, each entire Board, including all of the independent directors, approved the renewal of the existing Investment Advisory Agreement, concluding that the advisory fee, taking into account the fee waiver, was reasonable in relation to the services provided and that a contract renewal was in the best interests of the shareholders.
