MuniYield Pennsylvania Insured Fund 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 pays dividends at prevailing short-term interest rates, and invests 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 Common 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 of 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 October 31, 2005, the percentages of MuniYield Florida Insured Fund's, MuniYield New Jersey Insured Fund, Inc.'s and MuniYield Pennsylvania Insured Fund's total net assets invested in inverse floaters were 5.37%, 9.08% and 11.26%, respectively, before the deduction of Preferred Shares or Stock. ANNUAL REPORTS OCTOBER 31, 2005 A Letter From the President Dear Shareholder As the financial markets continued to muddle their way through 2005, the Federal Reserve Board (the Fed) advanced its monetary tightening campaign full steam ahead. The 12th consecutive interest rate hike since June 2004 came on November 1, bringing the target federal funds rate to 4%. The central bank is clearly more focused on inflationary figures than on economic growth, which has shown some signs of moderating. Despite rising short-term interest rates and record-high energy prices, the major market indexes managed to post positive results for the current reporting period: Total Returns as of October 31, 2005 6-month 12-month U.S. equities (Standard & Poor's 500 Index) + 5.27% + 8.72% Small-cap U.S. equities (Russell 2000 Index) +12.25 +12.08 International equities (MSCI Europe Australasia Far East Index) + 8.63 +18.09 Fixed income (Lehman Brothers Aggregate Bond Index) + 0.15 + 1.13 Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 0.59 + 2.54 High yield bonds (Credit Suisse First Boston High Yield Index) + 2.87 + 3.54 The headlines in recent months focused on Hurricanes Katrina and Rita and, more recently, the nomination of Ben Bernanke to succeed Alan Greenspan as Chairman of the Fed. While the hurricanes prompted a spike in energy prices and short-term disruptions to production and spending, the longer-term economic impact is likely to be tempered. In fact, the fiscal stimulus associated with reconstruction efforts in the Gulf Coast region could add to gross domestic product growth in 2006. Notably, the uncontroversial nomination of Dr. Bernanke was well received by the markets. The U.S. equity markets remained largely range bound in 2005. Up to this point, strong corporate earnings reports and relatively low long-term bond yields have worked in favor of equities. Looking ahead, high energy prices, continued interest rate hikes, a potential consumer slowdown and/or disappointing earnings pose the greatest risks to U.S. stocks. Internationally, many markets have benefited from strong economic statistics, trade surpluses and solid finances. The bond market continued to be characterized by a flattening yield curve, although long-term yields finally began to inch higher toward period end. The 10-year Treasury yield hit 4.57% on October 31, 2005, its highest level in more than six months. Still, the difference between the two-year and 10-year Treasury yield was just 17 basis points (.17%) at period end, compared to 149 basis points a year earlier. Financial markets are likely to face continued crosscurrents in the months ahead. Nevertheless, opportunities do exist and we encourage you to work with your financial advisor to diversify your portfolio among a variety of asset types. This can help to diffuse risk while also tapping into the potential benefits of a broader range of investment alternatives. As always, we thank you for trusting Merrill Lynch Investment Managers with your investment assets. Sincerely, (Robert C. Doll, Jr.) Robert C. Doll, Jr. President and Director/Trustee ANNUAL REPORTS OCTOBER 31, 2005 A Discussion With Your Funds' Portfolio Managers Throughout the year, we continued to focus on enhancing the income provided to shareholders and, by period-end, the Funds had relatively neutral exposure to interest rate risk. Describe the recent market environment relative to municipal bonds. Over the past year, long-term bond yields were little changed. Initially, U.S. Treasury prices rallied strongly, while their yields, which move in the opposite direction, fell. By the end of June 2005, 30-year U.S. Treasury bond yields had declined 60 basis points (.60%) to 4.19%. Bond prices improved in response to several favorable factors, including moderating U.S. economic growth, slowing growth in foreign economies, modest inflationary pressures and strong demand for U.S. Treasury issues on the part of Asian governments. During the final months of the period, however, bond yields rose (prices fell) as investors worried that higher energy costs in the wake of Hurricanes Katrina and Rita would pressure inflation upward. Stronger-than-expected third quarter gross domestic product growth also added to inflationary concerns. For its part, the Federal Reserve Board (the Fed) continued to raise short-term interest rates at each of its meetings, lifting the federal funds target rate to 4% on November 1, 2005. As short-term interest rates moved higher in concert with the Fed interest rate hikes and longer-term bond yields remained steadier, the yield curve continued to flatten. During the past 12 months, 30-year Treasury bond yields declined three basis points to 4.76%, while 10-year Treasury note yields rose 52 basis points to 4.57%. Tax-exempt bond yields exhibited a similar pattern. According to Municipal Market Data, the yield on AAA-rated issues maturing in 30 years increased one basis point to 4.59%, while the yield on AAA-rated issues maturing in 10 years rose 52 basis points to 3.92%. Historically low nominal tax-exempt bond yields continued to encourage municipalities to issue new debt and refund outstanding, higher-couponed issues. During the past year, more than $394 billion in new long-term tax- exempt bonds was issued, an 8.4% increase over the previous year's total of $363 billion. During the first nine months of 2005, the volume of refunding issues increased by more than 55% versus the same period one year ago. Refunding issues were heavily weighted in the 10-year - 20-year maturity range, putting pressure on intermediate tax-exempt bond yields while supporting longer-term bond prices. Investor demand for municipal product remained positive during most of the period. The most current statistics from the Investment Company Institute indicate that, year-to-date through September 2005, net new cash flows into long-term municipal bond funds exceeded $6.7 billion - a significant improvement from the $12.9 billion net outflow seen during the same period in 2004. Notably, throughout much of the past year, high yield tax-exempt bond funds have been the principal target for these new cash inflows. During recent months, these lower-rated and non-rated bond funds received an average of $115 million per week. The need to invest these cash flows has led to strong demand for lower-rated issues and a consequent narrowing of credit spreads. Solid investor demand for tax-exempt issues generally helped municipal bond performance approach that of taxable bonds in recent months and reverse some of their prior underperformance. In addition, the ratio of tax-exempt bond yields to taxable bond yields remains attractive and should continue to draw both traditional and non-traditional investors to the municipal marketplace, especially if municipal bond issuance remains manageable. The communities shattered by Hurricanes Katrina and Rita will require extensive reconstruction. It is too early to estimate the amount of tax-exempt debt that may be required to finance these efforts or to assess the overall impact on the municipal market. However, much of the rebuilding is likely to be funded through federal loans and grants, and the reconstruction will likely be spread over a number of years. Consequently, any new municipal bond issuance prompted by the hurricanes is not likely to disrupt the tax-exempt market in the near future. MuniYield Florida Insured Fund Describe conditions in the State of Florida. Florida maintains credit ratings of AA1 from Moody's, AAA from Standard & Poor's and AA+ from Fitch - all with stable trends. The favorable ratings are based on the state's solid economic and financial performance, in addition to moderate debt and a proactive government that responds to economic downturns faster than other states. Florida's continued economic strength is bolstered by robust population growth, which is attributed to the state's attractive physical environment and favorable business climate. Although the growth in population has put a strain on services such as education, transportation and healthcare, it also has allowed the state to recover more quickly from sub par economic trends. ANNUAL REPORTS OCTOBER 31, 2005 Currently, Florida's revenues are higher than budgeted and expenditures remain under control due to prudent fiscal oversight. The fiscal year 2005 budget 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. Given the government's concerns over the high healthcare costs facing the state, Governor Jeb Bush has proposed a partially private health insurance plan. Florida continues to maintain solid fund balances with consistent General Fund operations. In addition, the state has a working Capital Reserve Fund and a Budget Stabilization Fund in excess of $2 billion. How did the Fund perform during the fiscal year? For the 12-month period ended October 31, 2005, the Common Shares of MuniYield Florida Insured Fund had net annualized yields of 6.03% and 6.26%, based on a year-end per share net asset value of $14.72 and a per share market price of $14.18, respectively, and $.888 per share income dividends. Over the same period, the total investment return on the Fund's Common Shares was +2.72%, based on a change in per share net asset value from $15.22 to $14.72, and assuming reinvestment of all distributions. The Fund's return, based on net asset value, lagged the +3.81% average return of the Lipper Florida Municipal Debt Funds category for the 12-month period. (Funds in this Lipper category limit their investment to securities exempt from taxation in Florida or a city in Florida. Notably, the Fund has more limited investment parameters than many of its Lipper peers. Specifically, as an insured product, we are limited in our ability to invest in lower-quality issues. This placed the Fund at a competitive disadvantage as credit spreads tightened significantly and lower-rated and non-rated credits outperformed higher-quality issues. Factors that had a positive influence on Fund performance included our yield curve positioning. Essentially, we continued to focus on the longer end of the curve, which significantly outperformed the short end as the yield curve flattened and shorter-term bond prices suffered. Our large concentration in bonds with 5.50% and higher coupons also was additive to Fund results as these bonds outperformed those with lower coupons. Offsetting this was the aforementioned underexposure to lower-quality issues and the underperformance of prerefunded bonds and those with short calls, some of which we retained in the portfolio for their attractive acquisition yields. Overall, however, the Fund continued to provide a competitive yield and positive total return while investing in a portfolio consisting primarily of high-quality, insured bonds. For the six-month period ended October 31, 2005, the total investment return on the Fund's Common Shares was -.08%, based on a change in per share net asset value from $15.17 to $14.72, and assuming reinvestment of all distributions. 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 return based on changes in the Fund's net asset value. What changes were made to the portfolio during the 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 sought to sell some of the portfolio's prerefunded bonds in the five-year - 10-year maturity range. In doing so, we were cognizant not to sell bonds that were booked at higher yields than are available in the current market. ANNUAL REPORTS OCTOBER 31, 2005 A Discussion With Your Funds' Portfolio Managers (continued) In August, the Fund increased its use of leverage through the issuance of $12 million in additional Auction Market Preferred Shares (AMPS). With the proceeds, we generally focused on premium-coupon bonds in the 20-year - 25-year maturity range whenever they became available. This is where we have been able to capture higher yields with reduced volatility. Our efforts in this area have been somewhat limited by a lack of new long-term bonds in the Florida municipal market. Although new issuance increased 38% versus the previous 12-month period, much of the supply in the market has come in the form of refinancings, the majority of which offered maturities of only 15 years - 20 years and yields below 5%. Importantly, we remained fully invested throughout the fiscal year in order to augment the portfolio's yield. For the six-month period ended October 31, 2005, the Fund's AMPS had average yields of 2.45% for Series A and 2.43% for Series B. The Fed's interest rate hikes are clearly having a material impact on the Fund's borrowing costs. The Fed raised the short-term interest rate target 200 basis points during the 12-month period (and 25 basis points more on November 1). Still, the tax- exempt yield curve remained relatively steep and continued to generate an income benefit to the holders of Common Shares from the leveraging of Preferred Shares. However, 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 36.66% of total net assets, before the deduction of Preferred Shares. (For a more complete explanation of the benefits and risks of leveraging, see page 2 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 prefer to structure coupons of 5.25%. Long-term bond yields, which had been slow to react to the Fed's interest rate hikes, have started to inch upward. We will look for an increase in long-term rates as an opportunity to pursue higher- coupon bonds in the 20-year--30-year maturity range and will remain fully invested to augment shareholders' income. MuniYield New Jersey Insured Fund, Inc. Describe conditions in the State of New Jersey. New Jersey's fiscal year 2006 budget was passed on June 30, 2005. Shortly after, Standard & Poor's (S&P) upgraded the state's credit rating to AA while Moody's and Fitch affirmed the state's credit ratings of Aa3 and AA-, respectively, all with stable outlooks. The S&P rating was based largely on the state's improving revenue collections in fiscal year 2005 and a more structurally balanced 2006 budget when compared to the amount of one-time revenues used in the past several years. However, New Jersey's plan to use $150 million of tobacco settlement refinancing proceeds to balance the 2006 budget was challenged in court. The lawsuit alleged that using the proceeds in the budget was deficit funding and, therefore, was unconstitutional as ruled by New Jersey's Supreme Court last year when the state used revenue from securitizing motor vehicle surcharges and cigarette taxes to balance the budget. New Jersey's economy continued to show signs of recovery as revenues through the first 10 months of fiscal year 2005 came in better than budget. The largest revenue increase was in the income tax category, which rose by 31.7% compared to the prior year. Accordingly, one of New Jersey's strongest credit strengths is its high wealth levels. In fact, the U.S. Census Bureau reported in August that New Jersey was the wealthiest state in the nation with a median household income of $61,359. Connecticut placed second with a median household income of $60,528. However, New Jersey's unemployment rate rose to 4.2% in the month of August, up from 4.1% in July, 4% in June and 3.9% in May. Although the state's unemployment rate has trended upward, it compared favorably to the national rate of 4.9% in August. How did the Fund perform during the fiscal year? For the 12-month period ended October 31, 2005, the Common Stock of MuniYield New Jersey Insured Fund, Inc. had net annualized yields of 6.01% and 6.18%, based on a year-end per share net asset value of $15.07 and a per share market price of $14.65, respectively, and $.906 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +3.49%, based on a change in per share net asset value from $15.46 to $15.07, and assuming reinvestment of all distributions. ANNUAL REPORTS OCTOBER 31, 2005 The Fund's total return, based on net asset value, trailed the +4.88% average return of the Lipper New Jersey Municipal Debt Funds category for the 12-month period. (Funds in this Lipper category limit their investment to those securities exempt from taxation in New Jersey or a city in New Jersey.) Notably, the Fund was disadvantaged relative to many of its peers by its conservative investment parameters. Specifically, the Fund is limited in its ability to invest in lower-quality issues, which outperformed during the year as credit spreads (versus higher-quality issues of comparable maturity) tightened dramatically. Per its investment parameters, roughly 80% of the portfolio is invested in AAA-rated, insured bonds. Offsetting this was the positive influence of our yield curve positioning, which was designed to take advantage of what we expected would be a flattening trend, and the extension of the portfolio's duration to a more neutral posture. We moved a portion of bonds in the 10-year - 15-year maturity range further out on the curve to the 20-year - 25-year area. Our strategy paid off as the yield curve flattened and longer-term bonds significantly outpaced shorter-term issues. For the six-month period ended October 31, 2005, the total investment return on the Fund's Common Stock was -.30%, based on a change in per share net asset value from $15.56 to $15.07, and assuming reinvestment of all distributions. 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 may 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 continued to reallocate the portfolio's assets into longer-dated sectors of the municipal yield curve in an effort to capitalize on our view that the curve would flatten. New purchases were largely funded from the proceeds of bond calls as well as outright sales of relatively short, prerefunded bonds that had appreciated in value. Over the fiscal year, municipal bond supply in the State of New Jersey was roughly comparable to the same 12 months one year ago, at approximately $15 billion in long-term issuance. Notably, new issuance slowed in the last six months of the period. The past few months have seen a modest rise in interest rates, making refinancing a less attractive proposition. However, the slowdown in the new-issue calendar also reflects the fact that the state pursued the bulk of its refunding opportunities earlier in the year. Pending the outcome of the aforementioned legal challenge, new supply in the New Jersey municipal market could come in the form of a large refinancing of tobacco settlement bonds. For the six-month period ended October 31, 2005, the Fund's Auction Market Preferred Stock (AMPS) had an average yield of 2.20% for Series A and 2.08% for Series B. The Fed's interest rate hikes are clearly having a material impact on the Fund's borrowing costs. The Fed raised the short-term interest rate target 200 basis points during the 12-month period (and 25 basis points more on November 1). Still, the tax-exempt yield curve remained relatively steep and continued to generate an income benefit to the holders of Common Stock from the leveraging of Preferred Stock. However, 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 35.20% of total net assets, before the deduction of Preferred Stock. (For a more complete explanation of the benefits and risks of leveraging, see page 2 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? The Fund ended the period relatively neutral with respect to interest rate risk, and with a high-quality credit profile. For the most part, it appears that credit spreads have stabilized and, in some cases, widened - notably in the tobacco sector. Thus, we maintain an underweight exposure to this sector in anticipation of an increase in supply. We believe this should benefit the Fund's performance relative to its Lipper peers. ANNUAL REPORTS OCTOBER 31, 2005 A Discussion With Your Funds' Portfolio Managers (concluded) MuniYield Pennsylvania Insured Fund Describe conditions in the Commonwealth of Pennsylvania. Pennsylvania continued to protect its credit ratings of Aa2, AA and AA from Moody's, Standard & Poor's and Fitch, respectively, by maintaining conservative budgeting practices, a relatively low debt burden and a diversified service economy. Fiscal challenges in recent years were primarily managed with the drawdown of the commonwealth's rainy-day reserves and state- source tax increases. The recovery in the national economy also helped to bolster revenue growth and stabilized Pennsylvania's finances at a satisfactory level. General fund collections for fiscal year 2004-2005 are projected to exceed the official budget estimates by 1.9%, or $442 million. Year-over-year general fund revenues gained 6.5% as a result of strong growth in personal income and corporate taxes. The enacted 2005-2006 budget increases expenditures 3.6% over last year, for a budget of $24.6 billion. Major gubernatorial initiatives that will impact Pennsylvania's finances over the next several years include up to $2 billion in debt issuance to fund economic stimulus programs ranging from venture capital guarantees, real estate development and strengthening tourism and agricultural bases. The commonwealth's share of K-12 education expenditures will increase with local property tax reductions funded from slot machine tax revenues. Gaming revenues of approximately $1 billion from the installation of 61,000 slot machines at 12 facilities are expected to be realized in 2007. In a somewhat controversial move, Act 72 requires that school districts opt into the program by agreeing to tax limits and increasing earned income taxes in exchange for state dollars to lower property taxes. Broad-based job growth continues to be a favorable trend in the commonwealth. August 2005 employment was up 4,700 to 5,711,600, just under Pennsylvania's all-time high of 5,719,300 in 2001. The manufacturing sector provided just under 12% of employment and continues to show incremental contraction in contrast to the leading professional and business services, leisure and hospitality, and government sectors. Pennsylvania's unemployment rate was 5.0% in August, down from 5.1% in July. Personal income growth of 1.4% just trailed the U.S. average growth rate, ranking the Keystone State 34th in the second quarter of 2005, but overall reflected a wealth level on par with the nation. How did the Fund perform during the fiscal year? For the 12-month period ended October 31, 2005, the Common Shares of MuniYield Pennsylvania Insured Fund had net annualized yields of 6.09% and 6.36%, based on a year-end per share net asset value of $15.57 and a per share market price of $14.91, respectively, and $.948 per share income dividends. Over the same period, the total investment return on the Fund's Common Shares was +3.16%, based on a change in per share net asset value from $16.04 to $15.57, and assuming reinvestment of all distributions. The Fund provided an above-average yield during the 12-month period although its total return, based on net asset value, fell short of the +3.27% average return of the Lipper Pennsylvania Municipal Debt Funds category. (Funds in this Lipper category limit their investment to those securities exempt from taxation in Pennsylvania or a city in Pennsylvania.) Detracting from relative results was the Fund's conservative investment parameters. Unlike many of its Lipper peers, the Fund is limited in its ability to invest in lower-rated bonds, which outperformed the broader market during the year. The Fund's above-average duration also hindered performance somewhat. We had anticipated that Hurricanes Katrina and Rita would have a negative impact on the economy, at least initially, therefore benefiting credit markets (that is, increasing bond prices and decreasing yields). This prompted us to increase our average duration. However, it appeared that the markets and the Fed were more focused on rising energy costs and their potential to increase inflationary pressures. This served to push rates higher all along the yield curve. Offsetting these negative factors was our focus on the long end of the municipal yield curve. As the yield curve flattened considerably over the past year, long-term bonds outperformed shorter-term issues, and our focus on this segment of the curve benefited Fund performance. For the six-month period ended October 31, 2005, the total investment return on the Fund's Common Shares was -.31%, based on a change in per share net asset value from $16.09 to $15.57, and assuming reinvestment of all distributions. ANNUAL REPORTS OCTOBER 31, 2005 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 maintained our focus on protecting the Fund's net asset value and providing shareholders with an above-average level of income. We sought to pick up additional yield for the portfolio by investing in longer-dated bonds. Although the yield curve began to flatten considerably, the long end remained fairly steep. This area of the curve also has been less subject to bouts of volatility, allowing us the opportunity to add incremental yield while also muting the Fund's price volatility. For the most part, we favor bonds with 25-year - 28-year maturities and with premium coupons. Like the supply trends on the national level, issuance in Pennsylvania has tended to fall within the intermediate maturity range, largely because much of the new supply represents refunding issues. Overall, we expect that municipal issuance will begin to slow as interest rates increase and municipalities feel less compelled to refinance their debt. Importantly, the Fund was essentially fully invested throughout the period, consistent with our goal of maintaining an attractive level of income. For the six-month period ended October 31, 2005, the Fund's Auction Market Preferred Shares (AMPS) had an average yield of 2.40% for Series A, 2.46% for Series B and 2.40% for Series C. The Fed's interest rate hikes are clearly having a material impact on the Fund's borrowing costs. The Fed raised the short-term interest rate target 200 basis points during the 12-month period (and 25 basis points more on November 1). Still, the tax-exempt yield curve remained relatively steep and continued to generate an income benefit to the holders of Common Shares from the leveraging of Preferred Shares. However, 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 36.33% of total net assets, before the deduction of Preferred Shares. (For a more complete explanation of the benefits and risks of leveraging, see page 2 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? We believe the municipal yield curve will remain relatively steep when compared to the U.S. Treasury yield curve, which should continue to provide attractive opportunities on the long end. The Fed appears poised to continue pushing short-term interest rates higher in its effort to keep inflation contained. Amid these conditions, we expect market volatility to increase given continued hawkish commentary from the Fed and the potential for stronger economic releases. We will look to this volatility for opportunities to purchase attractively structured municipal issues. We continued to look for maturities in the 25-year area and favor a neutral to slightly long portfolio duration, which we believe offers the benefit of incremental yield. Ultimately, we expect that above-average yields will overcome price depreciation and provide for competitive Fund returns over time. Robert D. Sneeden Vice President and Portfolio Manager MuniYield Florida Insured Fund Theodore R. Jaeckel Jr., CFA Vice President and Portfolio Manager MuniYield New Jersey Insured Fund, Inc. William R. Bock Vice President and Portfolio Manager MuniYield Pennsylvania Insured Fund November 22, 2005 ANNUAL REPORTS OCTOBER 31, 2005 Automatic Dividend Reinvestment Plan How the Plan Works--The Funds offer a Dividend Reinvestment Plan (the "Plan") under which income and capital gains dividends paid by each Fund are automatically reinvested in additional shares of Common Stock of each Fund. The Plan is administered on behalf of the shareholders by The Bank of New York for MuniYield Florida Insured Fund and MuniYield New Jersey Insured Fund, Inc. and Equiserve Trust Company N.A. for MuniYield Pennsylvania Insured Fund (individually, the "Plan Agent" or together, the "Plan Agents"). Under the Plan, whenever the Funds declare a dividend, participants in the Plan will receive the equivalent in shares of Common Stock of each Fund. The Plan Agents will acquire the shares for the participant's account either (i) through receipt of additional unissued but authorized shares of each Fund ("newly issued shares") or (ii) by purchase of outstanding shares of Common Stock on the open market on the New York Stock Exchange or elsewhere. If, on the dividend payment date, each Fund's net asset value per share is equal to or less than the market price per share plus estimated brokerage commissions (a condition often referred to as a "market premium"), the Plan Agents will invest the dividend amount in newly issued shares. If the Funds' net asset value per share is greater than the market price per share (a condition often referred to as a "market discount"), the Plan Agents will invest the dividend amount by purchasing on the open market additional shares. If the Plan Agents are unable to invest the full dividend amount in open market purchases, or if the market discount shifts to a market premium during the purchase period, the Plan Agents will invest any uninvested portion in newly issued shares. The shares acquired are credited to each shareholder's account. The amount credited is determined by dividing the dollar amount of the dividend by either (i) when the shares are newly issued, the net asset value per share on the date the shares are issued or (ii) when shares are purchased in the open market, the average purchase price per share. Participation in the Plan--Participation in the Plan is automatic, that is, a shareholder is automatically enrolled in the Plan when he or she purchases shares of Common Stock of the Funds unless the shareholder specifically elects not to participate in the Plan. Shareholders who elect not to participate will receive all dividend distributions in cash. Shareholders who do not wish to participate in the Plan, must advise their Plan Agent in writing (at the address set forth below) that they elect not to participate in the Plan. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by writing to the Plan Agent. Benefits of the Plan--The Plan provides an easy, convenient way for shareholders to make additional, regular investments in the Funds. The Plan promotes a long-term strategy of investing at a lower cost. All shares acquired pursuant to the Plan receive voting rights. In addition, if the market price plus commissions of each Fund's shares is above the net asset value, participants in the Plan will receive shares of the Funds for less than they could otherwise purchase them and with a cash value greater than the value of any cash distribution they would have received. However, there may not be enough shares available in the market to make distributions in shares at prices below the net asset value. Also, since each Fund does not redeem shares, the price on resale may be more or less than the net asset value. Plan Fees--There are no enrollment fees or brokerage fees for participating in the Plan. The Plan Agents' service fees for handling the reinvestment of distributions are paid for by the Funds. However, brokerage commissions may be incurred when the Funds purchase shares on the open market and shareholders will pay a pro rata share of any such commissions. Tax Implications--The automatic reinvestment of dividends and distributions will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends. Therefore, income and capital gains may still be realized even though shareholders do not receive cash. The value of shares acquired pursuant to the Plan will generally be excluded from gross income to the extent that the cash amount reinvested would be excluded from gross income. If, when the Funds' shares are trading at a market premium, the Funds issue shares pursuant to the Plan that have a greater fair market value than the amount of cash reinvested, it is possible that all or a portion of the discount from the market value (which may not exceed 5% of the fair market value of each Fund's shares) could be viewed as a taxable distribution. If the discount is viewed as a taxable distribution, it is also possible that the taxable character of this discount would be allocable to all the shareholders, including shareholders who do not participate in the Plan. Thus, shareholders who do not participate in the Plan might be required to report as ordinary income a portion of their distributions equal to their allocable share of the discount. Contact Information--All correspondence concerning the Plan, including any questions about the Plan, should be directed to the Plan Agent at The Bank of New York, Church Street Station, P.O.

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 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 a swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligation 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.

See Notes to Financial Statements. ANNUAL REPORTS OCTOBER 31, 2005 Notes to Financial Statements 1. Significant Accounting Policies: MuniYield Florida Insured Fund, MuniYield New Jersey Insured Fund, Inc., and MuniYield Pennsylvania Insured Fund (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. The Funds determine and make available for publication the net asset value of their Common Stock/Shares on a daily basis. The Fund's Common Stock/ Shares are listed on the New York Stock Exchange under the symbol MFT for MuniYield Florida Insured Fund, MJI for MuniYield New Jersey Insured Fund, Inc., and MPA for MuniYield Pennsylvania Insured Fund. 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 markets 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 by quoted fair values received daily by the Funds' 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. * 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 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. * Options--Each Fund may purchase and write 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. * 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, the Fund records a realized gain or loss in an amount equal to the value of the agreement. ANNUAL REPORTS OCTOBER 31, 2005 Notes to Financial Statements (continued) (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. (f) Offering expenses--Direct expenses relating to the public offering of certain Fund's Preferred Stock/Shares were charged to capital. Any adjustments to estimates of offering costs were recorded back to capital. (g) Reclassification for MuniYield Pennsylvania Insured Fund--U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $19,772 has been reclassified between accumulated net realized capital losses and undistributed net investment income as a result of permanent differences attributable to amortization methods on fixed income securities. This reclassification has no effect on net assets or net asset values per share. 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 .50% of the Fund's average weekly net assets, including proceeds from the issuance of Preferred Stock/Shares. For the year ended October 31, 2005, the Investment Adviser agreed to reimburse its management fee by the amount of management fees each Fund pays to FAM indirectly through its investment described below: Investment Reimbursement MuniYield Florida Merrill Lynch Institutional Insured Fund Tax-Exempt Fund $3,088 MuniYield New Jersey CMA New Jersey Insured Fund, Inc.

These amounts will be available to offset like amounts of any future taxable gains. ** The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales, the tax deferral of losses on straddles and the difference between book and tax amortization methods for premiums and discounts on fixed income securities.

ANNUAL REPORTS OCTOBER 31, 2005 Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors/Trustees of MuniYield Florida Insured Fund, MuniYield New Jersey Insured Fund, Inc. and MuniYield Pennsylvania Insured Fund: We have audited the accompanying statements of net assets, including the schedules of investments, of MuniYield Florida Insured Fund, MuniYield New Jersey Insured Fund, Inc. and MuniYield Pennsylvania Insured Fund (the "Funds"), as of October 31, 2005, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, audits of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2005 by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the respective financial positions of MuniYield Florida Insured Fund, MuniYield New Jersey Insured Fund, Inc. and MuniYield Pennsylvania Insured Fund as of October 31, 2005, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

ANNUAL REPORTS OCTOBER 31, 2005 Disclosure of Investment Advisory Agreement Activities of and Composition of the Board of Directors (1) All but one member of each Fund's Board of Directors is an independent director whose only affiliation with Fund Asset Management, L.P. (the "Investment Adviser") or other Merrill Lynch affiliates is as a director of each Fund and as a 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 generally 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 over- seeing 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 with respect to each Fund separately, and include (a) information compiled by Lipper Inc. ("Lipper") on the fees and expenses and the investment performance 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; and (e) information provided by the Investment Adviser concerning investment advisory fees charged to other clients, such as offshore funds under similar investment mandates and generally to institutional clients. Each Board also considers other matters it deems important to the approval process such as services related to the valuation and pricing of Fund portfolio holdings, allocation of Fund brokerage fees, the Fund's portfolio turnover statistics, and direct and indirect benefits to the Investment Adviser and its affiliates from their relationship with the Fund. (1) References to directors shall include trustees. ANNUAL REPORTS OCTOBER 31, 2005 Disclosure of Investment Advisory Agreement (continued) Certain Specific Renewal Data In connection with the most recent renewal of each Fund's Investment Advisory Agreement in May 2005, 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 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 mutual funds, and the performance of a relevant index or combination of indexes. 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. The Board noted that for the period ended March 31, 2005, MuniYield Florida Insured Fund's performance was in the second quintile for the one-year period, and it ranked fourth out of five for the three-year period, and third out of four for the five-year period. The Board noted that the universe of comparable funds was very small. The Board noted that for the five-year period ended August 31, 2003, MuniYield New Jersey Insured Fund, Inc.'s performance was in the third quintile for the one-year period, the fifth quintile for the three-year period, and the third quintile for the five-year period. The Board noted that MuniYield Pennsylvania Insured Fund's performance was in the first quintile for each of the one-, three- and five-year periods ended August 31, 2003. Considering these factors, each Board concluded that the Fund's performance supported the continuation of the Investment Advisory Agreement. The Investment Adviser's Personnel and Investment Process--Each Board reviews at least annually the Fund's investment objectives and strategies. Each Board discusses 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 considers 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. Each Board also reviews the Investment Adviser's compensation policies and practices with respect to the Fund's portfolio managers. Each Board also considered the experience of the Fund's portfolio manager. The Board of MuniYield Florida Insured Fund noted that Mr. Sneeden has more than ten years of experience in portfolio management. The Board of MuniYield New Jersey Insured Fund, Inc. noted that Mr. Jaeckel has more than fifteen years of experience in portfolio management. The Board of MuniYield Pennsylvania Insured Fund noted that Mr. Bock has more than fifteen years of experience in portfolio management. The Investment Adviser and its investment staff have extensive experience in analyzing and managing the types of investments used by the Funds. Each Board concluded that the Fund benefits from that expertise. 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 in its Lipper category. It also compares the Fund's total expenses to those of other comparable funds. Each Board considered the services provided to and the fees charged by the Investment Adviser to other types of clients such as offshore funds, with similar investment mandates and noted that the fees charged by the Investment Adviser in those cases typically exceeded those being charged to the Fund. Each Board also noted that, as a general matter, fees charged to institutional clients were lower than the fees charged to the Fund, but believed that less extensive services were being provided to such clients. In the case of MuniYield Florida Insured Fund, the contractual management fee rate and total expenses are below the median of fees and expenses charged by comparable funds as determined by Lipper, while the actual management fee rate is slightly higher than the median fee charged by comparable funds. In the case of MuniYield New Jersey Insured Fund, Inc., the contractual management fee rate is lower than the median fee charged by comparable funds as determined by Lipper, while the actual management fee rate and total expenses are higher than the median fees and expenses charged by comparable funds. In the case of MuniYield Pennsylvania Insured Fund, the contractual management fee rate is below the median of fees charged by comparable funds as determined by Lipper, while the total expenses are equal to, and the actual management fee rate is slightly higher than, the median fees and expenses charged by comparable funds. Each Board has concluded that the Fund's management fee and fee rate and overall expense ratio are reasonable compared to those of other comparable funds. ANNUAL REPORTS OCTOBER 31, 2005 Disclosure of Investment Advisory Agreement (concluded) Profitability--Each Board considers the cost of the services provided to the Fund by the Investment Adviser, and the Investment Adviser's and its affiliates' profits in relation to the management and distribution 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. Each Board believes the Investment Adviser's profits are reasonable in relation to the nature and quality of services provided. The Boards also considered the federal court decisions discussing an investment adviser's profitability and profitability levels considered to be reasonable in those decisions. Economies of Scale--Each Board considered the extent to which economies of scale might be realized as the assets of the 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 currently 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 was reasonable in relation to the services provided and that a contract renewal was in the best interests of the shareholders.

Item 3 - Audit Committee Financial Expert - The registrant's board of directors has determined that (i) the registrant has the following audit committee financial experts serving on its audit committee and (ii) each audit committee financial expert is independent: (1) Donald W. Burton, (2) M. Colyer Crum (retired as of December 31, 2004), (3) Laurie Simon Hodrick, (4) John F. O'Brien (as of November 22, 2004), (5) David H. Walsh and (6) Fred G. Weiss. The registrant's board of directors has determined that Laurie Simon Hodrick and M. Colyer Crum qualify as financial experts pursuant to Item 3(c)(4) of Form N-CSR. Ms. Hodrick has a thorough understanding of generally accepted accounting principals, financial statements, and internal controls and procedures for financial reporting. Ms. Hodrick earned a Ph.D. in economics and has taught courses in finance for over 15 years. Her M.B.A.-level course centers around the evaluation and analysis of firms' corporate financial statements. She has also taught in financial analysts' training programs. Ms. Hodrick has also worked with several prominent corporations in connection with the analysis of financial forecasts and projections and analysis of the financial statements of those companies, serving on the Financial Advisory Council of one of these major corporations. She has also served as the Treasurer and Finance Chair of a 501(c)(3) organization. Ms. Hodrick has published a number of articles in leading economic and financial journals and is the associate editor of two leading finance journals. M. Colyer Crum also possesses a thorough understanding of generally accepted accounting principals, financial statements, and internal controls and procedures for financial reporting through a combination of education and experience. Professor Crum was a professor of investment management at the Harvard Business School for 25 years. The courses taught by Professor Crum place a heavy emphasis on the analysis of underlying company financial statements with respect to stock selection and the analysis of credit risk in making loans. Professor Crum has also served on a number of boards of directors and has served on the audit committees, and in some cases chaired the audit committee, for several major corporations and financial institutions. For two such organizations, Professor Crum has performed extensive investment analysis of financial statements in connection with investment management decisions. From these experiences, he has gained significant experience with the establishment of reserves and accounting policies, differences between U.S. GAAP and Canadian GAAP and executive compensation issues.

Weiss Item 6 - Schedule of Investments - Not Applicable Item 7 - Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies - Proxy Voting Policies and Procedures Each Fund's Board of Directors/Trustees has delegated to Merrill Lynch Investment Managers, L.P. and/or Fund Asset Management, L.P. (the "Investment Adviser") authority to vote all proxies relating to the Fund's portfolio securities. The Investment Adviser has adopted policies and procedures ("Proxy Voting Procedures") with respect to the voting of proxies related to the portfolio securities held in the account of one or more of its clients, including a Fund. Pursuant to these Proxy Voting Procedures, the Investment Adviser's primary objective when voting proxies is to make proxy voting decisions solely in the best interests of each Fund and its shareholders, and to act in a manner that the Investment Adviser believes is most likely to enhance the economic value of the securities held by the Fund. The Proxy Voting Procedures are designed to ensure that the Investment Adviser considers the interests of its clients, including the Funds, and not the interests of the Investment Adviser, when voting proxies and that real (or perceived) material conflicts that may arise between the Investment Adviser's interest and those of the Investment Adviser's clients are properly addressed and resolved. In order to implement the Proxy Voting Procedures, the Investment Adviser has formed a Proxy Voting Committee (the "Committee"). The Committee is comprised of the Investment Adviser's Chief Investment Officer (the "CIO"), one or more other senior investment professionals appointed by the CIO, portfolio managers and investment analysts appointed by the CIO and any other personnel the CIO deems appropriate. The Committee will also include two non- voting representatives from the Investment Adviser's Legal department appointed by the Investment Adviser's General Counsel. The Committee's membership shall be limited to full-time employees of the Investment Adviser. No person with any investment banking, trading, retail brokerage or research responsibilities for the Investment Adviser's affiliates may serve as a member of the Committee or participate in its decision making (except to the extent such person is asked by the Committee to present information to the Committee, on the same basis as other interested knowledgeable parties not affiliated with the Investment Adviser might be asked to do so). The Committee determines how to vote the proxies of all clients, including a Fund, that have delegated proxy voting authority to the Investment Adviser and seeks to ensure that all votes are consistent with the best interests of those clients and are free from unwarranted and inappropriate influences. The Committee establishes general proxy voting policies for the Investment Adviser and is responsible for determining how those policies are applied to specific proxy votes, in light of each issuer's unique structure, management, strategic options and, in certain circumstances, probable economic and other anticipated consequences of alternate actions. In so doing, the Committee may determine to vote a particular proxy in a manner contrary to its generally stated policies. In addition, the Committee will be responsible for ensuring that all reporting and recordkeeping requirements related to proxy voting are fulfilled. The Committee may determine that the subject matter of a recurring proxy issue is not suitable for general voting policies and requires a case-by-case determination. In such cases, the Committee may elect not to adopt a specific voting policy applicable to that issue. The Investment Adviser believes that certain proxy voting issues require investment analysis - such as approval of mergers and other significant corporate transactions - akin to investment decisions, and are, therefore, not suitable for general guidelines. The Committee may elect to adopt a common position for the Investment Adviser on certain proxy votes that are akin to investment decisions, or determine to permit the portfolio manager to make individual decisions on how best to maximize economic value for a Fund (similar to normal buy/sell investment decisions made by such portfolio managers). While it is expected that the Investment Adviser will generally seek to vote proxies over which the Investment Adviser exercises voting authority in a uniform manner for all the Investment Adviser's clients, the Committee, in conjunction with a Fund's portfolio manager, may determine that the Fund's specific circumstances require that its proxies be voted differently. To assist the Investment Adviser in voting proxies, the Committee has retained Institutional Shareholder Services ("ISS"). ISS is an independent adviser that specializes in providing a variety of fiduciary-level proxy-related services to institutional investment managers, plan sponsors, custodians, consultants, and other institutional investors. The services provided to the Investment Adviser by ISS include in-depth research, voting recommendations (although the Investment Adviser is not obligated to follow such recommendations), vote execution, and recordkeeping. ISS will also assist the Fund in fulfilling its reporting and recordkeeping obligations under the Investment Company Act. The Investment Adviser's Proxy Voting Procedures also address special circumstances that can arise in connection with proxy voting. For instance, under the Proxy Voting Procedures, the Investment Adviser generally will not seek to vote proxies related to portfolio securities that are on loan, although it may do so under certain circumstances. In addition, the Investment Adviser will vote proxies related to securities of foreign issuers only on a best efforts basis and may elect not to vote at all in certain countries where the Committee determines that the costs associated with voting generally outweigh the benefits. The Committee may at any time override these general policies if it determines that such action is in the best interests of a Fund. From time to time, the Investment Adviser may be required to vote proxies in respect of an issuer where an affiliate of the Investment Adviser (each, an "Affiliate"), or a money management or other client of the Investment Adviser (each, a "Client") is involved. The Proxy Voting Procedures and the Investment Adviser's adherence to those procedures are designed to address such conflicts of interest. The Committee intends to strictly adhere to the Proxy Voting Procedures in all proxy matters, including matters involving Affiliates and Clients. If, however, an issue representing a non-routine matter that is material to an Affiliate or a widely known Client is involved such that the Committee does not reasonably believe it is able to follow its guidelines (or if the particular proxy matter is not addressed by the guidelines) and vote impartially, the Committee may, in its discretion for the purposes of ensuring that an independent determination is reached, retain an independent fiduciary to advise the Committee on how to vote or to cast votes on behalf of the Investment Adviser's clients. In the event that the Committee determines not to retain an independent fiduciary, or it does not follow the advice of such an independent fiduciary, the powers of the Committee shall pass to a subcommittee, appointed by the CIO (with advice from the Secretary of the Committee), consisting solely of Committee members selected by the CIO. The CIO shall appoint to the subcommittee, where appropriate, only persons whose job responsibilities do not include contact with the Client and whose job evaluations would not be affected by the Investment Adviser's relationship with the Client (or failure to retain such relationship). The subcommittee shall determine whether and how to vote all proxies on behalf of the Investment Adviser's clients or, if the proxy matter is, in their judgment, akin to an investment decision, to defer to the applicable portfolio managers, provided that, if the subcommittee determines to alter the Investment Adviser's normal voting guidelines or, on matters where the Investment Adviser's policy is case-by-case, does not follow the voting recommendation of any proxy voting service or other independent fiduciary that may be retained to provide research or advice to the Investment Adviser on that matter, no proxies relating to the Client may be voted unless the Secretary, or in the Secretary's absence, the Assistant Secretary of the Committee concurs that the subcommittee's determination is consistent with the Investment Adviser's fiduciary duties In addition to the general principles outlined above, the Investment Adviser has adopted voting guidelines with respect to certain recurring proxy issues that are not expected to involve unusual circumstances. These policies are guidelines only, and the Investment Adviser may elect to vote differently from the recommendation set forth in a voting guideline if the Committee determines that it is in a Fund's best interest to do so. In addition, the guidelines may be reviewed at any time upon the request of a Committee member and may be amended or deleted upon the vote of a majority of Committee members present at a Committee meeting at which there is a quorum. The Investment Adviser has adopted specific voting guidelines with respect to the following proxy issues: * Proposals related to the composition of the Board of Directors of issuers other than investment companies. As a general matter, the Committee believes that a company's Board of Directors (rather than shareholders) is most likely to have access to important, nonpublic information regarding a company's business and prospects, and is therefore best-positioned to set corporate policy and oversee management. The Committee, therefore, believes that the foundation of good corporate governance is the election of qualified, independent corporate directors who are likely to diligently represent the interests of shareholders and oversee management of the corporation in a manner that will seek to maximize shareholder value over time. In individual cases, the Committee may look at a nominee's history of representing shareholder interests as a director of other companies or other factors, to the extent the Committee deems relevant. * Proposals related to the selection of an issuer's independent auditors. As a general matter, the Committee believes that corporate auditors have a responsibility to represent the interests of shareholders and provide an independent view on the propriety of financial reporting decisions of corporate management. While the Committee will generally defer to a corporation's choice of auditor, in individual cases, the Committee may look at an auditors' history of representing shareholder interests as auditor of other companies, to the extent the Committee deems relevant. * Proposals related to management compensation and employee benefits. As a general matter, the Committee favors disclosure of an issuer's compensation and benefit policies and opposes excessive compensation, but believes that compensation matters are normally best determined by an issuer's board of directors, rather than shareholders. Proposals to "micro-manage" an issuer's compensation practices or to set arbitrary restrictions on compensation or benefits will, therefore, generally not be supported. * Proposals related to requests, principally from management, for approval of amendments that would alter an issuer's capital structure. As a general matter, the Committee will support requests that enhance the rights of common shareholders and oppose requests that appear to be unreasonably dilutive. * Proposals related to requests for approval of amendments to an issuer's charter or by-laws. As a general matter, the Committee opposes poison pill provisions. * Routine proposals related to requests regarding the formalities of corporate meetings. * Proposals related to proxy issues associated solely with holdings of investment company shares. As with other types of companies, the Committee believes that a fund's Board of Directors (rather than its shareholders) is best-positioned to set fund policy and oversee management. However, the Committee opposes granting Boards of Directors authority over certain matters, such as changes to a fund's investment objective, that the Investment Company Act envisions will be approved directly by shareholders. * Proposals related to limiting corporate conduct in some manner that relates to the shareholder's environmental or social concerns. The Committee generally believes that annual shareholder meetings are inappropriate forums for discussion of larger social issues, and opposes shareholder resolutions "micromanaging" corporate conduct or requesting release of information that would not help a shareholder evaluate an investment in the corporation as an economic matter. While the Committee is generally supportive of proposals to require corporate disclosure of matters that seem relevant and material to the economic interests of shareholders, the Committee is generally not supportive of proposals to require disclosure of corporate matters for other purposes. Item 8 - Portfolio Managers of Closed-End Management Investment Companies - as of October 31, 2005. (a)(1) Mr. William R. Bock is primarily responsible for the day-to-day management of the registrant's portfolio ("Portfolio Manager"). Mr. Bock is a Director of MLIM and has been a portfolio manager at MLIM since 1989. He has twelve years of experience investing in Municipal Bonds. He has been the portfolio manager and a Vice President of the Fund since 1997. (a)(2) As of October 31, 2005: (iii) Number of Other Accounts and (ii) Number of Other Accounts Managed Assets for Which Advisory Fee is and Assets by Account Type Performance-Based Other Other (i) Name of Registered Other Pooled Registered Other Pooled Portfolio Investment Investment Other Investment Investment Other Manager Companies Vehicles Accounts Companies Vehicles Accounts William R. Bock 3 0 0 0 0 0 $ 2,568,590,927 $ 0 $ 0 $ 0 $ 0 $ 0 (iv) Potential Material Conflicts of Interest Real, potential or apparent conflicts of interest may arise when a portfolio manager has day-to-day portfolio management responsibilities with respect to more than one fund or account, including the following: Certain investments may be appropriate for the Fund and also for other clients advised by the Investment. Adviser and its affiliates, including other client accounts managed by the Fund's portfolio management team. Investment decisions for the Fund and other clients are made with a view to achieving their respective investment objectives and after consideration of such factors as their current holdings, availability of cash for investment and the size of their investments generally. Frequently, a particular security may be bought or sold for only one client or in different amounts and at different times for more than one but less than all clients. Likewise, because clients of the Investment Adviser and its affiliates may have differing investment strategies, a particular security may be bought for one or more clients when one or more other clients are selling the security. The investment results for the Fund may differ from the results achieved by other clients of the Investment Adviser and its affiliates and results among clients may differ. In addition, purchases or sales of the same security may be made for two or more clients on the same day. In such event, such transactions will be allocated among the clients in a manner believed by the Investment Adviser and its affiliates to be equitable to each. The Investment Adviser will not determine allocations based on whether it receives a performance based fee from the client. In some cases, the allocation procedure could have an adverse effect on the price or amount of the securities purchased or sold by the Fund. Purchase and sale orders for the Fund may be combined with those of other clients of the Investment Adviser and its affiliates in the interest of achieving the most favorable net results to the Fund. To the extent that the Fund's portfolio management team has responsibilities for managing accounts in addition to the Fund, a portfolio manager will need to divide his time and attention among relevant accounts. In some cases, a real, potential or apparent conflict may also arise where (i) the Investment Adviser may have an incentive, such as a performance based fee, in managing one account and not with respect to other accounts it manages or (ii) where a member of the Fund's portfolio management team owns an interest in one fund or account he or she manages and not another. (a)(3) As of October 31, 2005: Portfolio Manager Compensation The Portfolio Manager Compensation Program of MLIM and its affiliates, including the Investment Adviser, is critical to MLIM's ability to attract and retain the most talented asset management professionals. This program ensures that compensation is aligned with maximizing investment returns and it provides a competitive pay opportunity for competitive performance. Compensation Program The elements of total compensation for MLIM and its affiliates portfolio managers are a fixed base salary, annual performance-based cash and stock compensation (cash and stock bonus) and other benefits. MLIM has balanced these components of pay to provide portfolio managers with a powerful incentive to achieve consistently superior investment performance. By design, portfolio manager compensation levels fluctuate - both up and down - with the relative investment performance of the portfolios that they manage. Base Salary Under the MLIM approach, like that of many asset management firms, base salaries represent a relatively small portion of a portfolio manager's total compensation. This approach serves to enhance the motivational value of the performance-based (and therefore variable) compensation elements of the compensation program. Performance-Based Compensation MLIM believes that the best interests of investors are served by recruiting and retaining exceptional asset management talent and managing their compensation within a consistent and disciplined framework that emphasizes pay for performance in the context of an intensely competitive market for talent. To that end, MLIM and its affiliates portfolio manager incentive compensation is based on a formulaic compensation program. MLIM's formulaic portfolio manager compensation program includes: investment performance relative to a subset of general closed-end, Pennsylvania municipal debt funds over 1-, 3- and 5-year performance periods and a measure of operational efficiency. Portfolio managers are compensated based on the pre-tax performance of the products they manage. If a portfolio manager's tenure is less than 5 years, performance periods will reflect time in position. Portfolio managers are compensated based on products they manage. A discretionary element of portfolio manager compensation may include consideration of: financial results, expense control, profit margins, strategic planning and implementation, quality of client service, market share, corporate reputation, capital allocation, compliance and risk control, leadership, workforce diversity, supervision, technology and innovation. MLIM and its affiliates also consider the extent to which individuals exemplify and foster ML & Co.'s principles of client focus, respect for the individual, teamwork, responsible citizenship and integrity. All factors are considered collectively by MLIM management. Cash Bonus Performance-based compensation is distributed to portfolio managers in a combination of cash and stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for portfolio managers. Stock Bonus A portion of the dollar value of the total annual performance-based bonus is paid in restricted shares of ML & Co. stock. Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year "at risk" based on the company's ability to sustain and improve its performance over future periods. The ultimate value of stock bonuses is dependent on future ML & Co. stock price performance. As such, the stock bonus aligns each portfolio manager's financial interests with those of the ML & Co. shareholders and encourages a balance between short-term goals and long-term strategic objectives. Management strongly believes that providing a significant portion of competitive performance-based compensation in stock is in the best interests of investors and shareholders. This approach ensures that portfolio managers participate as shareholders in both the "downside risk" and "upside opportunity" of the company's performance. Portfolio managers therefore have a direct incentive to protect ML & Co.'s reputation for integrity. Other Compensation Programs Portfolio managers who meet relative investment performance and financial management objectives during a performance year are eligible to participate in a deferred cash program. Awards under this program are in the form of deferred cash that may be benchmarked to a menu of MLIM mutual funds (including their own fund) during a five-year vesting period. The deferred cash program aligns the interests of participating portfolio managers with the investment results of MLIM products and promotes continuity of successful portfolio management teams. Other Benefits Portfolio managers are also eligible to participate in broad-based plans offered generally to employees of ML & Co. and its affiliates, including broad-based retirement, 401(k), health, and other employee benefit plans. (a)(4) Beneficial Ownership of Securities. As of October 31, 2005, Mr. Bock does not beneficially own any stock issued by the Fund.
