After a volatile start and far-reaching mid-year correction, the financial markets regained some positive momentum through late summer and fall. For the six- and 12-month periods ended October 31, 2006, most major market indexes managed to post positive returns: Total Returns as of October 31, 2006 6-month 12-month =============================================================================================== U.S. equities (Standard & Poor's 500 Index) +6.11% +16.34% ----------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) +0.90 +19.98 ----------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) +3.77 +27.52 ----------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers Aggregate Bond Index) +4.60 + 5.19 ----------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +4.12 + 5.75 ----------------------------------------------------------------------------------------------- High yield bonds (Credit Suisse High Yield Index) +4.66 +10.29 ----------------------------------------------------------------------------------------------- The Federal Reserve Board (the Fed), after raising the target short-term interest rate 17 times between June 2004 and June 2006, finally opted to pause on August 8, 2006. This left the federal funds rate at 5.25%, where it remained through the September and October Fed meetings. In interrupting its two-year rate-hiking campaign, the Fed acknowledged that economic growth is slowing, led by softness in the housing market. However, the central bankers continue to take a cautionary position on inflation, despite a decline in energy prices in recent months. At the time of this writing, the price of oil had settled into the $60-per-barrel range after reaching nearly $78 per barrel earlier in the year. Notwithstanding the mid-year correction, equity markets generally found support in solid corporate earnings reports in the first three quarters of the year. Overall corporate health, including strong company balance sheets, helped to sustain robust dividend-distribution, share-buyback and merger-and-acquisition activity. Many international equity markets fared equally well or better, thanks in part to higher economic growth rates and low inflation. In the U.S. bond market, prices declined for much of the year as investors focused on decent economic activity and inflation concerns. Bond prices began to improve in late June as the economy showed signs of weakening and inflation pressures subsided. Notably, the Treasury curve inverted periodically, a phenomenon typically associated with periods of economic weakness. At the end of October, the one-month Treasury bill offered the highest yield on the curve at 5.18%, while the 30-year Treasury bond had a yield of 4.72%. Amid the uncertainty inherent in the financial markets, we encourage you to review your goals periodically with your financial professional and to make portfolio changes, as needed.

We are pleased to make our investor-friendly magazine available to you online. We thank you for trusting BlackRock 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 ANNUAL REPORTS OCTOBER 31, 2006 3 A Discussion With Your Funds' Portfolio Managers The Funds recorded total returns that surpassed their respective Lipper group averages for the fiscal year, while also continuing to provide shareholders with an attractive monthly income stream. Describe the recent market environment relative to municipal bonds. Supported by a positive technical backdrop, municipal bonds managed to significantly outperform their taxable counterparts for the 12-month period ended October 31, 2006. Despite considerable volatility, taxable bond yields were little changed over the past year. Tax-exempt bonds, in the meantime, saw their yields decline (as prices, which move opposite of yields, rose). For much of the first half of the fiscal period, longer-maturity U.S. Treasury bond yields rose (and prices declined) as investors focused on strong U.S. economic activity and inflationary concerns triggered by rising oil prices. By mid-May 2006, the yield on 30-year U.S. Treasury bonds rose more than 70 basis points (.70%) to 5.31%. Bond prices began to improve in late June as economic activity weakened and inflationary pressures subsided. Bond price improvement accelerated after the Federal Reserve Board (the Fed) refrained from raising the target interest rate at its August 8 meeting, a move that came after 17 consecutive interest rate hikes since June 2004. Recent declines in oil prices, and especially gasoline prices, helped to reverse earlier inflationary concerns and support higher bond prices. Over the 12-month period, 30-year U.S. Treasury bond yields fell four basis points to 4.72%, while 10-year Treasury yields rose four basis points to 4.61%. Meanwhile, the municipal bond market found support in declining new-issue volume and increasing investor demand. As reported by Municipal Market Data, yields on AAA-rated municipal issues maturing in 30 years declined 52 basis points to 4.07% over the past 12 months. Shorter maturities experienced smaller yield declines, with yields on AAA-rated municipal issues maturing in 10 years falling 28 basis points to 3.64%. Demand for municipal product by retail and institutional investors has remained very strong despite the recent decline in bond yields. The strong demand is reflected in continued flows into long-term, tax-exempt mutual funds. As reported by the Investment Company Institute, long-term municipal bond funds saw net new cash inflows of more than $1.3 billion during September 2006, a material increase from $344 million in July and $283 million in June. During the first nine months of 2006, long-term tax-exempt bond funds had net new cash flows of over $9.6 billion, a 43% increase versus the same period a year earlier. Recent weekly fund flows, reported by AMG Data, averaged $416 million in October 2006, well above the July average of $247 million and the year-to-date weekly average of $315 million. Also supporting municipal bond price improvement has been a decline in new issuance. In the first 10 months of 2006, more than $295 billion in new long-term municipal bonds was underwritten, a decline of over 12.5% versus the same period a year ago. Notably, after declining for much of the year, refunding activity increased slightly in October as the lower interest rate environment sparked an increase in refinancing activity. On a year-to-date basis, however, refunding activity has declined over 50% relative to last year's refunding issuance. Looking ahead, the positive technical framework in the municipal marketplace suggests that the tax-exempt market should continue to perform well. New supply is expected to remain manageable and tax-exempt bond yield ratios remain in their recent range of 86% - 89% of comparable long-term U.S. Treasury yields, well within their recent historic norms. These ratios argue for continued strong demand from non-traditional, arbitrage-related accounts, which continue to be attracted to the municipal bond market given its relatively steep yield curve. Taken together, these factors suggest that the municipal market is poised to continue to perform well as we approach year-end. 4 ANNUAL REPORTS OCTOBER 31, 2006 BlackRock MuniYield Fund, Inc. How did the Fund perform during the fiscal year? For the 12-month period ended October 31, 2006, the Common Stock of BlackRock MuniYield Fund, Inc. (formerly MuniYield Fund, Inc.) had net annualized yields of 6.23% and 5.92%, based on a year-end per share net asset value of $14.98 and a per share market price of $15.76, respectively, and $.933 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +10.30%, based on a change in per share net asset value from $14.48 to $14.98, and assuming reinvestment of all distributions. The Fund's total return, based on net asset value, exceeded the +8.42% average return of the Lipper General Municipal Debt Funds (Leveraged) category for the 12-month period. (Funds in this Lipper category invest primarily in municipal debt issues rated in the top four credit-rating categories. These funds can be leveraged via use of debt, preferred equity and/or reverse repurchase agreements.) As in prior reporting periods, Fund performance continued to be driven by our exposure to lower-rated, higher-yielding credits. As credit spreads contracted throughout the period, lower-rated instruments outperformed the broader market and provided both price appreciation and incremental yield for the Fund. It should be noted that the spread contraction trend slowed considerably over the latter six months of the period, and the benefits of the Fund's spread product exposure decreased. Still, positive security selection kept the Fund's performance ahead of the median of its Lipper peer group throughout the 12-month period. Another factor benefiting performance was our active management of the portfolio's duration, or its sensitivity to interest rate risk. Entering the fiscal year, we had a neutral duration posture compared to our Lipper peers, with the intention of lengthening that position slightly going into the end of 2005, which we did. In light of market improvement, we subsequently shortened our duration modestly in a timely move ahead of the market backup that occurred in the beginning of 2006. Through the last six months of the period, we maintained a generally neutral duration, although we have remained flexible with respect to market moves. We also continued to position the portfolio to take advantage of the flattening trend in the municipal yield curve. The curve did flatten over the 12 months, further benefiting Fund performance. For the six-month period ended October 31, 2006, the total investment return on the Fund's Common Stock was +6.03%, based on a change in per share net asset value from $14.57 to $14.98, 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? Portfolio activity during the period was focused on taking advantage of the further flattening of the municipal yield curve, as well as improving the overall quality and diversification of the Fund. Our yield curve strategy evolved in response to municipal market moves over the 12-month period. In the first half of the period, we typically made purchases in the 20-year - 30-year maturity range using proceeds from the sale of bonds with much shorter maturities, such as those in the five-year - 10-year area. We also looked to sell longer bonds that were likely to be called by their issuers in that five-year - 10-year time frame. As we perceived a shift in value to the 10-year - 15-year maturity range, we focused our buying activity in that area of the curve during the latter half of the period. Most notably, we participated in the initial offering of a New Jersey Transportation Trust Fund debt refinancing transaction, which was worth $2.8 billion and included a number of attractively priced opportunities in the 15-year sector. While we have been reluctant to fund these purchases by selling bonds at the long end of the curve, which may yet benefit from additional flattening, we believe the Fund will be better served by a shift to the intermediate range. In addition to pursuing our yield curve strategy, we also sought opportunities to reduce our weighting in non-investment grade, high yield bonds. Given the demand for high yield issues that was initially sparked by high call activity in the low interest rate environment of the last few years, we were able to sell bonds that we believed had become overvalued and were unlikely to continue their outperformance. Despite the loss of yield associated with our reductions in high yield paper, ANNUAL REPORTS OCTOBER 31, 2006 5 A Discussion With Your Funds' Portfolio Managers (continued) the Fund performed quite well throughout the 12-month period as the high yield positions that were retained, particularly those in the health care and airline sectors, continued to outperform. For the six-month period ended October 31, 2006, the Fund's Auction Market Preferred Stock had average yields of: 3.27% for Series A, 3.24% for Series B, 3.38% for Series C, 3.30% for Series D, 3.21% for Series E, 3.22% for Series F and 3.23% for Series G. The Fed raised short-term interest rates six times during the 12-month period, but opted to keep the target rate on hold at 5.25% in August, September and October 2006. As such, the Fund's borrowing costs started to stabilize and even move slightly lower late in the period. Despite the Fed's rate increases during the period, the municipal yield curve remained positively sloped and continued to generate an income benefit to the Common Stock shareholder from the leveraging of Preferred Stock. However, should the spread between short-term and long-term interest rates narrow, the benefits of leverage will decline and, as a result, reduce the yield on the Fund's Common Stock. (For a more complete explanation of the benefits and risks of leveraging, see page 11 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? At period-end, the Fund was neutrally positioned in terms of interest rate risk, and our exposure to lower-rated securities had been reduced. Our yield curve outlook changed during the period as it became likely that the Fed would pause in its monetary tightening program, which it did in the third quarter of 2006. With the majority of the curve flattening likely behind us, we began the process of reducing our exposure to the long end of the curve over the latter half of the reporting period. We now see that the most attractive value is closer to the middle of the curve, around the 10-year - 15-year range. We will continue to use periods of market strength to sell high yield issues and those at the long end of the yield curve in order to further improve the portfolio's credit quality and allocate more assets to the intermediate part of the curve. BlackRock MuniYield Insured Fund, Inc. How did the Fund perform during the fiscal year? For the 12-month period ended October 31, 2006, the Common Stock of BlackRock MuniYield Insured Fund, Inc. (formerly MuniYield Insured Fund, Inc.) had net annualized yields of 4.99% and 5.31%, based on a year-end per share net asset value of $15.30 and a per share market price of $14.36, respectively, and $.763 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +8.09%, based on a change in per share net asset value from $15.27 to $15.30, and assuming reinvestment of all distributions. The Fund's total return, based on net asset value, exceeded the +7.11% average return of the Lipper Insured Municipal Debt Funds (Leveraged) category for the 12-month period. (Funds in this Lipper category invest primarily in municipal debt issues insured as to timely payment. These funds can be leveraged via use of debt, preferred equity and/or reverse repurchase agreements.) The Fund's outperformance can be attributed to a few factors, including our focus on bonds issued by high-tax and specialty states and our emphasis on the long end of the municipal yield curve. The Fund was able to realize price outperformance from its holdings of bonds issued by higher-tax states such as California and New York. Approximately 33% of the Fund's assets was allocated to California and 15.4% to New York municipal issues, which performed well and boosted Fund performance for the year. We also purchased bonds issued by specialty states, such as Nebraska, Kansas and Missouri, where favorable supply/demand dynamics led to solid price performance for these states' bonds. Finally, the Fund's slightly longer maturity compared to its peers proved advantageous as the yield curve continued to flatten and long-term bonds outperformed short-term issues. This strategy also helped the portfolio to maintain an above-average yield. For the six-month period ended October 31, 2006, the total investment return on the Fund's Common Stock was +5.68%, based on a change in per share net asset value from $14.85 to $15.30, 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 6 ANNUAL REPORTS OCTOBER 31, 2006 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? We did not significantly alter our strategy or the Fund's portfolio during the past 12 months. We continued to target additional yield for the portfolio by investing in longer-dated bonds, specifically in the 25-year - 30-year maturity range, while also seeking to protect the Fund's underlying value. As new municipal bond issuance declined during the year, we found few compelling opportunities to restructure the portfolio. Having said that, we did notice a marked narrowing of credit spreads between municipal bonds issued by high-tax states and those issued by low-tax states and sought to capitalize on this trend. When available, we found it advantageous to purchase high-quality bonds issued by the high-tax states, as opposed to bonds issued by low-tax states. Because of the relatively high income taxes imposed by these states, their securities typically meet with strong retail demand, which in turn creates a solid technical market, leading to better liquidity. We participated in these transactions in such high-tax states as California, New York and New Jersey. In our efforts to maintain a diversified portfolio, we also bought approximately $30 million in general obligation bonds of the State of Louisiana. Although these issues came with shorter maturities than we had been targeting, this was a rare opportunity to participate in the Louisiana debt market in bonds that were offering yields comparable to other states' 30-year issues. We also found a number of compelling opportunities in the Pacific Northwest, specifically bonds issued by the State of Washington. These made up approximately 10% - 11% of the portfolio at period-end. We observe solid credit fundamentals in this region of the country. Importantly, the Fund continued to be fully invested throughout the period, consistent with our goal of maintaining an attractive level of income. For the six-month period ended October 31, 2006, the Fund's Auction Market Preferred Stock had average yields of: 3.05% for Series A, 3.00% for Series B, 2.97% for Series C, 3.12% for Series D, 2.92% for Series E, 3.06% for Series F, 2.86% for Series G, 2.90% for Series H and 2.87% for Series I. The Fed raised short-term interest rates six times during the 12-month period, but opted to keep the target rate on hold at 5.25% in August, September and October 2006. As such, the Fund's borrowing costs began to stabilize and even move slightly lower late in the period. Despite the Fed's interest rate increases during the period, the municipal yield curve remained positively sloped and continued to generate an income benefit to the Common Stock shareholder from the leveraging of Preferred Stock. However, should the spread between short-term and long-term interest rates narrow, the benefits of leverage will decline and, as a result, reduce the yield on the Fund's Common Stock. (For a more complete explanation of the benefits and risks of leveraging, see page 11 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? We ended the period with a fully invested portfolio and a slightly long duration relative to our peers. Municipal yields and credit spreads are near their all-time lows and the slope of the yield curve is historically very flat. However, a favorable supply/demand environment should continue to be supportive of present valuations in the municipal market. Against this backdrop, we intend to continue our efforts to enhance yield for shareholders while also protecting the Fund's underlying value. To that end, we continue to look for maturities in the 25-year area and to favor a neutral to slightly long portfolio duration, which we believe offers the benefit of incremental yield. Recently, we started looking down the yield curve slightly at opportunities in the 15-year - 17-year area. Ultimately, we believe that above-average yields can provide for competitive Fund returns over time. ANNUAL REPORTS OCTOBER 31, 2006 7 A Discussion With Your Funds' Portfolio Managers (continued) BlackRock MuniYield Quality Fund, Inc. How did the Fund perform during the fiscal year? For the 12-month period ended October 31, 2006, the Common Stock of BlackRock MuniYield Quality Fund, Inc. (formerly MuniYield Quality Fund, Inc.) had net annualized yields of 5.04% and 5.33%, based on a year-end per share net asset value of $15.32 and a per share market price of $14.48, respectively, and $.772 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +7.78%, based on a change in per share net asset value from $15.02 to $15.32, and assuming reinvestment of all distributions. The Fund's total return, based on net asset value, outpaced the +7.11% average return of the Lipper Insured Municipal Debt Funds (Leveraged) category for the 12-month period. (Funds in this Lipper category invest primarily in municipal debt issues insured as to timely payment. These funds can be leveraged via use of debt, preferred equity and/or reverse repurchase agreements.) The Fund also provided an above-average yield relative to its Lipper peers. The bulk of the Fund's outperformance occurred in the latter six months of the fiscal year, when our fully invested position allowed the portfolio to take advantage of the bond market rally that ensued once the Fed stopped raising interest rates. Also contributing to performance was the Fund's above-average yield, which is additive to total return, and the advance refunding of several positions. When bonds are refunded ahead of their maturity date, they generally rise sharply in value. The price appreciation was somewhat more muted given the flatness of the yield curve, but prerefundings are a special event nonetheless and contributed to the positive performance of the Fund during this 12-month period. For the six-month period ended October 31, 2006, the total investment return on the Fund's Common Stock was +5.62%, based on a change in per share net asset value from $14.89 to $15.32, 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 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? Municipal bonds fared quite well during the year, supported by low new issuance, healthy investor demand and strong performance relative to the taxable bond market. We did not make significant changes to the portfolio's composition or our investment strategy over the past 12 months. Given the limited supply in the market, and the generally low coupons available on new issues, there were few compelling opportunities to restructure the portfolio. We did sell some of the recently advance refunded positions, as their book yields were not significantly above current market yields, and moved into higher-yielding current issues. For the most part, we targeted the 20-year maturity range for the relative yield enhancement it offered. Nevertheless, we were reluctant to restructure the portfolio significantly, as most of the securities held in the portfolio have higher yields than those currently available in the market. Overall, we maintained a fairly neutral duration profile for most of the period and a fully invested stance. Both of these factors aided performance, particularly as the bond markets embarked on a strong rally in the final three months of the period. In managing the Fund's duration, we employed hedging strategies rather than trading in and out of bonds. We felt this was a prudent approach, as it allowed us to target our desired duration without having to give up attractively structured bonds that contribute meaningfully to the Fund's distribution rate. 8 ANNUAL REPORTS OCTOBER 31, 2006 For the six-month period ended October 31, 2006, the Fund's Auction Market Preferred Stock had average yields of 3.32% for Series A, 3.24% for Series B, 3.38% for Series C, 3.26% for Series D and 3.23% for Series E. The Fed raised short-term interest rates six times during the 12-month period, but opted to keep the target rate on hold at 5.25% in August, September and October 2006. As such, the Fund's borrowing costs began to stabilize and even move slightly lower late in the period. Despite the Fed's interest rate increases during the period, the municipal yield curve remained positively sloped and continued to generate an income benefit to the Common Stock shareholder from the leveraging of Preferred Stock. However, should the spread between short-term and long-term interest rates narrow, the benefits of leverage will decline and, as a result, reduce the yield on the Fund's Common Stock. (For a more complete explanation of the benefits and risks of leveraging, see page 11 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? We remained fully invested at period-end and fairly neutral with respect to interest rate risk. The bond market has come a long way in recent months, despite some uncertain rhetoric from the Fed. The central bankers acknowledge that the economy is slowing, led by a sharp deceleration in housing, but continue to take a cautionary tone on inflation. Against this backdrop, we believe a neutral stance is appropriate. We will look to sell into strength as the market presents opportunities, particularly at the longer end of the curve. We also continue to explore opportunities back down the curve in the 15-year - 20-year range. We have found that we can move five years - 10 years down the curve without sacrificing a significant amount of yield. Given the degree of yield-curve flattening that has occurred over the course of the Fed's interest rate-hiking campaign, we believe this maturity range could perform well in the future. Overall, we remain committed to our goal of providing shareholders with an attractive level of tax-exempt income. BlackRock MuniYield Quality Fund II, Inc. How did the Fund perform during the fiscal year? For the 12-month period ended October 31, 2006, the Common Stock of BlackRock MuniYield Quality Fund II, Inc. (formerly MuniYield Quality II Fund, Inc.) had net annualized yields of 5.12% and 5.40%, based on a year-end per share net asset value of $13.64 and a per share market price of $12.93, respectively, and $.698 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +7.98%, based on a change in per share net asset value from $13.36 to $13.64, and assuming reinvestment of all distributions. The Fund's total return, based on net asset value, outpaced the +7.11% average return of the Lipper Insured Municipal Debt Funds (Leveraged) category for the 12-month period. (Funds in this Lipper category invest primarily in municipal debt issues insured as to timely payment. These funds can be leveraged via use of debt, preferred equity and/or reverse repurchase agreements.) The Fund also provided an above-average yield relative to its Lipper peers.

The price appreciation was somewhat more muted given the flatness of the yield curve, but prerefundings are a special event nonetheless and contributed to the positive performance of the Fund during this 12-month period. For the six-month period ended October 31, 2006, the total investment return on the Fund's Common Stock was +5.74%, based on a change in per share net asset value from $13.25 to $13.64, and assuming reinvestment of all distributions. ANNUAL REPORTS OCTOBER 31, 2006 9 A Discussion With Your Funds' Portfolio Managers (concluded) 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? Municipal bonds fared quite well during the year, supported by low new issuance, healthy investor demand and strong performance relative to the taxable bond market. We did not make significant changes to the portfolio's composition or our investment strategy over the past 12 months. Given the limited supply in the market, and the generally low coupons available on new issues, there were few compelling opportunities to restructure the portfolio. We did sell some of the recently advance refunded positions, as their book yields were not significantly above current market yields, and moved into higher-yielding current issues. For the most part, we targeted the 20-year maturity range for the relative yield enhancement it offered. Nevertheless, we were reluctant to restructure the portfolio significantly, as most of the securities held in the portfolio have higher yields than those currently available in the market. Overall, we maintained a fairly neutral duration profile for most of the period and a fully invested stance. Both of these factors aided performance, particularly as the bond markets embarked on a strong rally in the final three months of the period. In managing the Fund's duration, we employed hedging strategies rather than trading in and out of bonds. We felt this was a prudent approach, as it allowed us to target our desired duration without having to give up attractively structured bonds that contribute meaningfully to the Fund's distribution rate. For the six-month period ended October 31, 2006, the Fund's Auction Market Preferred Stock had average yields of 3.33% for Series A, 3.44% for Series B, 3.21% for Series C and 3.22% for Series D. The Fed raised short-term interest rates six times during the 12-month period, but opted to keep the target rate on hold at 5.25% in August, September and October 2006. As such, the Fund's borrowing costs began to stabilize during the period, the municipal yield curve remained positively sloped and continued to generate an income benefit to the Common Stock shareholder from the leveraging of Preferred Stock. However, should the spread between short-term and long-term interest rates narrow, the benefits of leverage will decline and, as a result, reduce the yield on the Fund's Common Stock. (For a more complete explanation of the benefits and risks of leveraging, see page 11 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? We remained fully invested at period-end and fairly neutral with respect to interest rate risk. The bond market has come a long way in recent months, despite some uncertain rhetoric from the Fed. The central bankers acknowledge that the economy is slowing, led by a sharp deceleration in housing, but continue to take a cautionary tone on inflation. Against this backdrop, we believe a neutral stance is appropriate. We will look to sell into strength as the market presents opportunities, particularly at the longer end of the curve. We also continue to explore opportunities back down the curve in the 15-year - 20-year range. We have found that we can move five years - 10 years down the curve without sacrificing a significant amount of yield. Given the degree of yield-curve flattening that has occurred over the course of the Fed's interest rate-hiking campaign, we believe this maturity range could perform well in the future. Overall, we remain committed to our goal of providing shareholders with an attractive level of tax-exempt income. Theodore R.

November 20, 2006 10 ANNUAL REPORTS OCTOBER 31, 2006 The Benefits and Risks of Leveraging The Funds utilize leveraging to seek to enhance the yield and net asset value of their Common Stock. However, these objectives cannot be achieved in all interest rate environments. To leverage, each Fund issues Preferred 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 Stock, is paid to 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 each Fund's Common Stock. However, in order to benefit 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 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 Stock capitalization of $100 million and the issuance of Preferred 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 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 Stock shareholders are significantly lower than the income earned on the fund's long-term investments, and therefore the 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 Stock will be reduced or eliminated completely. At the same time, the market value of the fund's Common 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 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 Stock does not fluctuate. In addition to the decline in net asset value, the market value of the fund's Common Stock may also decline. As of October 31, 2006, BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and MuniYield Quality Fund II, Inc. had leverage amounts, due to Auction Market Preferred Stock, of 33.78%, 35.62%, 34.92% and 34.40% of total net assets, respectively, before the deduction of Preferred Stock. 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. 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 obligations to pay the other party to the agreement.

See Notes to Financial Statements. 42 ANNUAL REPORTS OCTOBER 31, 2006 Notes to Financial Statements 1. Significant Accounting Policies: On September 29, 2006, MuniYield Fund, Inc., MuniYield Insured Fund, Inc., MuniYield Quality Fund, Inc. and MuniYield Quality Fund II, Inc. were renamed BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. (the "Funds" or individually as the "Fund"), respectively. The Funds 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 on a daily basis. The Funds' Common Stock shares are listed on the New York Stock Exchange under the symbol MYD for BlackRock MuniYield Fund, Inc., MYI for BlackRock MuniYield Insured Fund, Inc., MQY for BlackRock MuniYield Quality Fund, Inc. and MQT for BlackRock MuniYield Quality Fund II, Inc. 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 each of the Funds under the general direction of the respective Board of Directors. Such valuations and procedures are reviewed periodically by the Boards of Directors 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. Options traded in the OTC market are valued at 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 each Fund's Board of Directors of the Funds. (b) Derivative financial instruments -- Each Fund may engage in various portfolio investment strategies both to increase the return of each 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 financial futures contracts. Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. o Options -- 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. 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, ANNUAL REPORTS OCTOBER 31, 2006 43 Notes to Financial Statements (continued) the Fund records a realized gain or loss in an amount equal to the value of the agreement. o Swaps -- Each Fund may enter into swap agreements, which are OTC contracts in which the Fund and a counterparty agree to make periodic net payments on a specified notional amount. The net payments can be made for a set period of time or may be triggered by a predetermined credit event. The net periodic payments may be based on a fixed or variable interest rate; the change in market value of a specified security, basket of securities, or index; or the return generated by a security. These periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively. Gains or losses are also realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. (c) Municipal bonds held in trust -- Certain Funds invest in leveraged residual certificates ("TOB Residuals") issued by tender option bond trusts ("TOBs"). A TOB is established by a third party sponsor forming a special purpose entity, into which a Fund, or an agent on behalf of the Fund, transfers municipal securities. A TOB typically issues two classes of beneficial interests: short-term floating rate certificates, which are sold to third party investors, and residual certificates, which are generally issued to the Fund which made the transfer or to affiliates of the Fund. Each Fund's transfers of the municipal securities to a TOB do not qualify for sale treatment under Statement of Financial Accounting Standards No. 140 "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities," therefore the municipal securities deposited into a TOB are presented in the Funds' schedules of investments and the proceeds from the transactions are reported as liability for trust certificates. Similarly, proceeds from residual certificates issued to affiliates, if any, from the transaction are included in the liability for trust certificates. Interest income from the underlying security is recorded by the Funds on an accrual basis. Interest expense incurred on the secured borrowing and other expenses related to remarketing, administration and trustee services to a TOB are reported as expenses of a Fund. The floating rate certificates have interest rates that generally reset weekly and their holders have the option to tender certificates to the TOB for redemption at par at each reset date. The residual interests held by the Funds include the right of the Funds (1) to cause the holders of a proportional share of floating rate certificates to tender their certificates at par, and (2) to transfer a corresponding share of the municipal securities from the TOB to the Funds. At October 31, 2006, the aggregate value of the underlying municipal securities transferred to TOBs and the liability for trust certificates were: -------------------------------------------------------------------------------- Underlying Municipal Liability Range of Bonds for Trust Interest Transferred Certificates Rates to TOBs -------------------------------------------------------------------------------- BlackRock MuniYield Fund, Inc. ......................... $ 36,112,500 3.59% $ 78,662,771 BlackRock MuniYield Insured Fund, Inc. ................. $174,115,000 3.59-3.63% $375,135,650 BlackRock MuniYield Quality Fund, Inc. ................. $ 85,427,072 3.58-3.61% $176,779,808 BlackRock MuniYield Quality Fund II, Inc. .............. $ 50,510,000 3.59-3.61% $107,063,961 ================================================================================ Financial transactions executed through TOBs generally will under perform the market for fixed rate municipal bonds in a rising interest rate environment, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable. Should short-term interest rates rise, a Fund's investment in TOB Residuals likely will adversely affect a Fund's investment income-net and distributions to shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect the Fund's net asset value per share. While the Funds' investment policies and restrictions expressly permit investments in inverse floating rate securities such as TOB Residuals, they generally do not allow the Funds to borrow money for purposes of making investments. The Funds' management believes that the Funds' restrictions on borrowings do not apply to the secured borrowings deemed to have occurred for accounting purposes. (d) 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. (e) 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. 44 ANNUAL REPORTS OCTOBER 31, 2006 Notes to Financial Statements (continued) Interest income is recognized on the accrual basis. The Funds amortize all premiums and discounts on debt securities. (f) Dividends and distributions -- Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (g) Offering costs -- Direct expenses relating to the public offering of each Fund's Preferred Stock were charged to capital at the time of issuance of the shares. Any adjustments to estimates of offering costs were recorded back to capital. (h) Recent accounting pronouncements -- In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity including mutual funds before being measured and recognized in the financial statements. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006. The impact on each of the Fund's financial statements, if any, is currently being assessed. In addition, in September 2006, Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the implications of FAS 157. At this time its impact on each of the Fund's financial statements has not been determined. (i) Reclassifications -- BlackRock MuniYield Fund, Inc. 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, $90 has been reclassified between undistributed net investment income and accumulated net realized capital losses as a result of permanent differences attributable to distributions in excess of capital gains. This reclassification has no effect on net assets or net asset values per share. BlackRock MuniYield Insured Fund, Inc. 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, $5,774,512 has been reclassified between paid-in capital in excess of par and accumulated net realized capital losses and $307 has been reclassified between undistributed net investment income and accumulated net realized capital losses as a result of permanent differences attributable to distributions in excess of realized capital gains and the reclassification of distributions. These reclassifications have no effect on net assets or net asset values per share. BlackRock MuniYield Quality Fund, Inc. 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, $244 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.

Restatement Information: During the year ended October 31, 2006, each of the Funds determined that the criteria for sale accounting in Statement of Financial Accounting Standards No. 140 had not been met for certain transfers of municipal bonds and that these transfers should have been accounted for as secured borrowings rather than as sales. Accordingly, BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc., and BlackRock MuniYield Quality Fund II, Inc. each has restated its Statement of Changes in Net Assets for the year ended October 31, 2005 to give effect to offsetting changes in realized gain -- net and in the change in unrealized appreciation/ depreciation-net on the transferred municipal securities. Additionally, each of the Funds, including BlackRock MuniYield Fund, Inc., has restated its financial highlights for the years ended October 31, 2005, 2004, 2003 and 2002 to give effect to recording the transfers of the municipal bonds as secured borrowings, including recording interest on the bonds as interest income and interest on the secured borrowings as interest expense. 48 ANNUAL REPORTS OCTOBER 31, 2006 Notes to Financial Statements (continued) ---------------------------------------------------------------------------------------------------------------------------------- Statements of Changes in Net Assets For the Year Ended October 31, 2005 ---------------------------------------------------------------------------------------------------------------------------------- BlackRock MuniYield BlackRock MuniYield BlackRock MuniYield Insured Fund, Inc.

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, 2006, 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 of BlackRock MuniYield Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. referred to above present fairly, in all material respects, the respective financial positions of each of those funds as of October 31, 2006, 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, their financial highlights for each of the five years in the period then ended, and, for BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc., their cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America. Additionally, in our opinion, the financial statements and financial highlights of BlackRock MuniYield Insured Fund, Inc. as of and for the year ended October 31, 2006, present fairly, in all material respects, its financial position as of October 31, 2006, and the results of its operations, changes in its net assets and its financial highlights for the year then ended, in conformity with accounting principles generally accepted in the United States of America. As discussed in Note 6, the statements of changes in net assets of BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. for the year ended October 31, 2005, and their respective financial highlights for each of the four years in the period then ended have been restated. As also discussed in Note 6, the financial highlights of BlackRock MuniYield Fund, Inc. for each of the four years in the period ended October 31, 2005 have been restated. ANNUAL REPORTS OCTOBER 31, 2006 51 Report of Independent Registered Public Accounting Firm (concluded) We also have audited the adjustments, applied by management, to restate the statement of changes in net assets of BlackRock MuniYield Insured Fund, Inc. (the "Insured Fund") for the year ended October 31, 2005 and certain financial highlights of the Insured Fund for each of the four years in the period then ended, to correct the errors described in Note 6. These adjustments are the responsibility of the Insured Fund's management. The audit procedures that we performed with respect to the adjustments included such tests as we considered necessary in the circumstances and were designed to obtain reasonable assurance about whether the adjustments are appropriate and have been properly applied, in all material respects, to the restated statement of changes in net assets of the Insured Fund for the year ended October 31, 2005, and to the restated information in its financial highlights for each of the four years in the period then ended. We did not perform any audit procedures designed to assess whether any additional adjustments or disclosures to the Insured Fund's financial statements or financial highlights as of October 31, 2005, and for each of the four years in the period then ended, might be necessary in order for such financial statements or financial highlights to be presented in conformity with generally accepted accounting principles. In our opinion, the adjustments to the statement of changes in net assets of the Insured Fund for the year ended October 31, 2005, and to its financial highlights for each of the four years in the period then ended, for the restatement described in Note 6 are appropriate and have been properly applied, in all material respects. However, we were not engaged to audit, review, or apply any procedures to the Insured Fund's financial statements or financial highlights as of October 31, 2005, and for each of the four years in the period then ended, other than with respect to the adjustments to the Insured Fund's statement of changes in net assets and its financial highlights for the restatement described in Note 6 and, accordingly, we do not express an opinion or any other form of assurance on the Insured Fund's financial statements as of October 31, 2005, or on its financial highlights for each of the four years in the period then ended.

(the "Fund"). E&Y's reports on the financial statements of the Fund for the past two fiscal years did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. In connection with its audits for the two most recent fiscal years and through August 28, 2006 (1) there were no disagreements with E&Y on any matter of accounting principle or practice, financial statement disclosure or auditing scope or procedure, whereby such disagreements, if not resolved to the satisfaction of E&Y, would have caused them to make reference to the subject matter of the disagreements in connection with their report on the financial statements for such years; and (2) there have been no reportable events (as defined in item 304(a)(1)(v) of Regulation S-K).

("FAM"), each Fund's investment adviser at that time. Activities and Composition of the Boards All but one member of each Board is an independent director whose only affiliation with FAM or other Merrill Lynch affiliates was as a director of the Fund and as a director or trustee of certain other funds advised by FAM or its affiliates. The Co-chairmen of each Board are also independent directors. New director nominees are chosen 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. Each Board and each Board's 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. FAM Investment Advisory Agreements -- Matters Considered by the Boards Every year, each Fund's Board considers approval of the Fund's investment advisory agreement. Each Board assesses the nature, scope and quality of the services provided to the 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 the 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 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 noted its view of FAM as one of the most experienced global asset management firms and considered the overall services provided by FAM to be of high quality. Each Board also noted its view of FAM as financially sound and well managed and noted FAM's affiliation 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 Approval by the Boards 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 each Fund's market price with its net asset value per share; (c) a discussion by the Fund's portfolio management team regarding 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 retail closed-end funds, under similar investment mandates. Each Board also considers other matters it deems important to the approval process, such as payments made for 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. Certain Specific Renewal Data In connection with the most recent renewal of each Fund's investment advisory agreement with FAM (each, a "FAM Investment Advisory Agreement") in August 2006, the independent directors' and the Board's review included the following: ANNUAL REPORTS OCTOBER 31, 2006 57 Disclosure of Investment Advisory Agreement (concluded) Services Provided by the Investment Adviser -- Each Fund's Board reviewed the nature, extent and quality of services provided by FAM, focusing on the investment advisory services and the resulting performance of the Fund. Each Board uses data provided by Lipper and by management in its review of advisory services. Each Board compared Fund performance -- both including and excluding the effects of the Fund's fees and expenses -- to the performance of a comparable group of funds and the performance of a relevant index or combination of indexes. While each Board reviews performance data at least quarterly, each Board attaches more importance to performance over relatively long periods of time, typically three to five years. Each Fund's Board concluded that the comparative data indicated that the Fund's performance was competitive. Considering all these factors, each Fund's Board concluded that the nature and quality of the services provided supported the continuation of the Fund's FAM Investment Advisory Agreement. FAM's Personnel and Investment Process -- Each Fund's Board reviewed the Fund's investment objectives and strategies. Each Board discussed with FAM's senior management responsible for investment operations and the senior management of FAM's municipal investing group the strategies being used to achieve the stated objectives. Among other things, each Board considered the size, education and experience of FAM's investment staff, its use of technology, and FAM's approach to training and retaining portfolio managers and other research, advisory and management personnel. Each Board also reviewed FAM'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 Fund, Inc. noted that Mr. Jaeckel has more than 15 years of experience in portfolio management, the Board of MuniYield Insured Fund, Inc. noted that Mr. Bock has more than 15 years of experience in portfolio management and the Boards of MuniYield Quality Fund, Inc. and MuniYield Quality Fund II, Inc. noted that Mr. Kalinoski has more than five years of experience in portfolio management. Each Fund's Board concluded that FAM and its investment staff have extensive experience in analyzing and managing the types of investments used by the Fund and that the Fund benefits from that experience. Management Fees and Other Expenses -- Each Fund's 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 FAM to other clients with similar investment mandates. Each Fund's Board determined that the Fund's contractual and actual management fee rates, as well as total expenses, were competitive with those of comparable funds. Each Fund's Board concluded that the Fund's management fee rate and overall expense ratio were reasonable. 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 relating to the management and distribution of the Fund and the funds advised by the investment manager and its affiliates. As part of its analysis, each Fund's Board reviewed FAM's methodology in allocating its costs to the management of the Fund and concluded that there was a reasonable basis for the allocation. The Board concluded that the profits of FAM and its affiliates were acceptable in relation to the nature and quality of services provided. Economies of Scale -- Each Fund's 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 Fund's Board considered economies of scale to the extent applicable to the Fund's closed-end structure and determined that the Fund appropriately benefits from any economies of scale. Each Board determined that the management fee structure was reasonable and that no changes were currently necessary. Conclusion -- After the independent directors of each Board deliberated in executive session, the entire Board of each Fund, including all of the independent directors, approved the renewal of the pertinent FAM 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. 58 ANNUAL REPORTS OCTOBER 31, 2006 Disclosure of New Investment Advisory Agreement New BlackRock Investment Advisory Agreements -- Matters Considered by the Boards In connection with the combination of Merrill Lynch's investment advisory business, including Fund Asset Management, L.P. (the "Previous Investment Adviser"), with that of BlackRock, Inc. ("BlackRock") to create a new independent company ("New BlackRock") (the "Transaction"), each Fund's Board of Directors considered and approved a new investment advisory agreement (each, a "BlackRock Investment Advisory Agreement") between the Fund and BlackRock Advisors, LLC ("BlackRock Advisors"). Each Fund's shareholders subsequently approved the Fund's BlackRock Investment Advisory Agreement and it became effective on September 29, 2006, replacing the Fund's investment advisory agreement with the Previous Investment Adviser (each, a "Previous Investment Advisory Agreement"). Each Fund's Board discussed the Fund's BlackRock Investment Advisory Agreement at telephonic and in-person meetings held during April and May 2006. Each Fund's Board, including the independent directors, approved the Fund's BlackRock Investment Advisory Agreement at an in-person meeting held on May 9, 2006. To assist each Fund's Board in its consideration of the Fund's BlackRock Investment Advisory Agreement, BlackRock provided materials and information about BlackRock, including its financial condition and asset management capabilities and organization, and Merrill Lynch provided materials and information about the Transaction. Each Fund's independent directors, through their independent legal counsel, also requested and received additional information from Merrill Lynch and BlackRock in connection with their consideration of the Fund's BlackRock Investment Advisory Agreement. The additional information was provided in advance of the May 9, 2006 meetings. In addition, each Fund's independent directors consulted with their counsel and Fund counsel on numerous occasions, discussing, among other things, the legal standards and certain other considerations relevant to the directors' deliberations. At each Fund's Board meetings, the directors discussed with Merrill Lynch management and certain BlackRock representatives the Transaction, its strategic rationale and BlackRock's general plans and intentions regarding the Fund. At these Board meetings, representatives of Merrill Lynch and BlackRock made presentations to and responded to questions from the Boards. The directors also inquired about the plans for and anticipated roles and responsibilities of certain employees and officers of the Previous Investment Adviser, and of its affiliates, to be transferred to BlackRock in connection with the Transaction. The independent directors also conferred separately and with their counsel about the Transaction and other matters related to the Transaction on a number of occasions, including in connection with the April and May 2006 meetings. After the presentations and after reviewing the written materials provided, each Fund's independent directors met in executive sessions with their counsel to consider the Fund's BlackRock Investment Advisory Agreement. In connection with the directors' review of each Fund's BlackRock Investment Advisory Agreement, Merrill Lynch and/or BlackRock advised the directors about a variety of matters. The advice included the following, among other matters: o that there was not expected to be any diminution in the nature, quality and extent of services provided to any of the Funds or their shareholders by BlackRock Advisors, including compliance services; o that operation of New BlackRock as an independent investment management firm would enhance its ability to attract and retain talented professionals; o that each Fund was expected to benefit from having access to BlackRock's state of the art technology and risk management analytic tools, including investment tools, provided under the BlackRock Solutions(R) brand name; o that BlackRock had no present intention to alter any applicable expense waivers or reimbursements that were currently in effect and, while it reserved the right to do so in the future, it would seek Board approval before making any changes; o that in connection with the Transaction, Merrill Lynch and BlackRock had agreed to conduct, and use reasonable best efforts to cause their respective affiliates to conduct, their respective businesses in compliance with the conditions of Section 15(f) of the Investment Company Act of 1940 (the "1940 Act") in relation to any public funds advised by BlackRock or the Previous Investment Adviser (or affiliates), respectively; and o that Merrill Lynch and BlackRock would derive benefits from the Transaction and that, as a result, they had a financial interest in the matters being considered that was different from that of Fund shareholders. ANNUAL REPORTS OCTOBER 31, 2006 59 Disclosure of New Investment Advisory Agreement (continued) The directors considered the information provided by Merrill Lynch and BlackRock above, and, among other factors, the following: o the potential benefits to each Fund's shareholders from being part of a combined fund family with BlackRock-sponsored funds, including possible economies of scale and access to investment opportunities; o the reputation, financial strength and resources of BlackRock and its investment advisory subsidiaries and the anticipated financial strength and resources of New BlackRock; o the compliance policies and procedures of BlackRock Advisors; o the terms and conditions of each Fund's BlackRock Investment Advisory Agreement, including the fact that no Fund's schedule of total advisory fees would increase under the pertinent BlackRock Investment Advisory Agreement, but would remain the same; o that in August 2005, each Fund's Board had performed a full annual review of the pertinent Previous Investment Advisory Agreement, as required by the 1940 Act, and had determined that the Previous Investment Adviser had the capabilities, resources and personnel necessary to provide the advisory and administrative services that were then being provided to the Fund; and that the advisory and/or management fees paid by the Fund, taking into account any applicable agreed-upon fee waivers and breakpoints, had represented reasonable compensation to the Previous Investment Adviser in light of the services provided, the costs to the Previous Investment Adviser of providing those services, economies of scale, the fees and other expenses paid by similar funds (including information provided by Lipper Inc. ["Lipper"]), and such other matters as the directors had considered relevant in the exercise of their reasonable judgment; and o that Merrill Lynch had agreed to pay all expenses of each Fund in connection with the consideration by the Board of the Fund's BlackRock Investment Advisory Agreement and related agreements and all costs of shareholder approval of the BlackRock Investment Advisory Agreement and as a result the Fund would bear no costs in obtaining shareholder approval of the BlackRock Investment Advisory Agreement. Certain of these considerations are discussed in more detail below. In its review of the Fund's BlackRock Investment Advisory Agreement, each Fund's Board assessed the nature, quality and scope of the services to be provided to the Fund by the personnel of BlackRock Advisors and its affiliates, including administrative services, shareholder services, oversight of fund accounting and assistance in meeting legal and regulatory requirements. In its review of the Fund's BlackRock Investment Advisory Agreement, each Fund's Board also considered a range of information in connection with its oversight of the services to be provided by BlackRock Advisors and its affiliates. Among the matters considered for each Fund were: (a) fees (in addition to management fees) to be paid to BlackRock Advisors and its affiliates by the Fund; (b) Fund operating expenses paid to third parties; (c) the resources devoted to and compliance reports relating to the Fund's investment objective, policies and restrictions, and its compliance with its Code of Ethics and BlackRock Advisors' compliance policies and procedures; and (d) the nature, cost and character of non-investment management services to be provided by BlackRock Advisors and its affiliates. In the period prior to each Fund's Board meeting to consider renewal of the Fund's Previous Investment Advisory Agreement, the Board had requested and received materials specifically relating to the Previous Investment Advisory Agreement. For each Fund, these materials included (a) information compiled by 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 on investment strategies used by the Fund during its most recent fiscal year; (d) information on the profitability to the Previous Investment Adviser of the Fund's Previous Investment Advisory Agreement and other payments received by the Previous Investment Adviser and its affiliates from the Fund; and (e) information provided by the Previous Investment Adviser concerning services related to the valuation and pricing of Fund portfolio holdings, the Fund's portfolio turnover statistics, and direct and indirect benefits to the Previous Investment Adviser and its affiliates from their relationship with the Fund. In their deliberations, each Fund's directors considered information received in connection with their most recent approval of the continuance of the Fund's Previous Investment Advisory Agreement, in addition to information 60 ANNUAL REPORTS OCTOBER 31, 2006 provided by BlackRock and BlackRock Advisors in connection with their evaluation of the terms and conditions of the Fund's BlackRock Investment Advisory Agreement. None of the Funds' directors identified any particular information that was all-important or controlling. Each Fund's directors, including a majority of the independent directors, concluded that the terms of the Fund's BlackRock Investment Advisory Agreement are appropriate, that the fees to be paid are reasonable in light of the services to be provided to the Fund, and that the BlackRock Investment Advisory Agreement should be approved and recommended to Fund shareholders. Nature, Quality and Extent of Services Provided -- Each Fund's Board reviewed the nature, quality and scope of services provided by the Previous Investment Adviser, including the investment advisory services and the resulting performance of the Fund, as well as the nature, quality and extent of services expected to be provided by BlackRock Advisors. Each Fund's Board focused primarily on the Previous Investment Adviser's investment advisory services and the Fund's investment performance, but also considered certain areas in which both the Previous Investment Adviser and the Fund received services as part of the Merrill Lynch complex. Each Fund's Board compared the Fund's performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of funds, and the performance of a relevant index or combination of indexes. While each Board reviews performance data at least quarterly, consistent with the Previous Investment Adviser's investment goals, the Board attaches more importance to performance over relatively long periods of time, typically three to five years. In evaluating the nature, quality and extent of the services to be provided by BlackRock Advisors under each Fund's BlackRock Investment Advisory Agreement, the directors considered, among other things, the expected impact of the Transaction on the operations, facilities, organization and personnel of New BlackRock and how it would affect the Fund; the ability of BlackRock Advisors to perform its duties after the Transaction; and any anticipated changes to the investment and other practices of the Fund. Each Fund's directors were given information with respect to the potential benefits to the Fund and its shareholders from having access to BlackRock's state of the art technology and risk management analytic tools, including the investment tools provided under the BlackRock Solutions brand name. Each Fund's directors were advised that, as a result of Merrill Lynch's equity interest in BlackRock after the Transaction, the Fund would continue to be subject to restrictions concerning certain transactions involving Merrill Lynch affiliates (for example, transactions with a Merrill Lynch broker-dealer acting as principal) absent revised or new regulatory relief. Each Fund's directors were advised that a revision of existing regulatory relief with respect to these restrictions was being sought from the Securities and Exchange Commission and were advised of the possibility of the receipt of such revised regulatory relief. Based on their review of the materials provided and the assurances they had received from the management of Merrill Lynch and of BlackRock, each Fund's directors determined that the nature and quality of services to be provided to the Fund under the Fund's BlackRock Investment Advisory Agreement were expected to be as good as or better than that provided under the Fund's Previous Investment Advisory Agreement. The directors were advised that BlackRock Advisors did not plan to change any of the Funds' portfolio management team upon the closing of the transaction. It was noted, however, that other changes in personnel were expected to follow the Transaction and the combination of the operations of the Previous Investment Adviser and its affiliates with those of BlackRock. Each Fund's directors noted that if current portfolio managers or other personnel were to cease to be available prior to the closing of the Transaction, the Board would consider all available options, including seeking the investment advisory or other services of BlackRock affiliates. Accordingly, each Fund's directors concluded that, overall, they were satisfied with assurances from BlackRock and BlackRock Advisors as to the expected nature, quality and extent of the services to be provided to the Fund under the Fund's BlackRock Investment Advisory Agreement. Costs of Services Provided, Fees and Profitability -- It was noted that, in conjunction with their recent review of the Fund's Previous Investment Advisory Agreement, each Fund's directors had received, among other things, a report from Lipper comparing the Fund's fees and expenses to those of a peer group selected by Lipper, and information as to the fees charged by the Previous Investment Adviser or its affiliates to other registered investment company clients for investment management services. Each Fund's Board reviewed 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 fees and the effects of any fee waivers -- compared to the other funds in its Lipper category. Each Fund's Board also compared the ANNUAL REPORTS OCTOBER 31, 2006 61 Disclosure of New Investment Advisory Agreement (concluded) Fund's total expenses to those of other comparable funds. The information showed that each Fund had fees and expenses within the range of fees and expenses of comparable funds. Each Fund's Board considered the services to be provided by and the fees to be charged by BlackRock Advisors to other funds with similar investment mandates and noted that the fees charged by BlackRock Advisors in those cases, including fee waivers and expense reimbursements, were generally comparable to those being charged to the Fund. Each Fund's Board concluded that the Fund's management fee and fee rate and overall expense ratio are reasonable compared to those of other comparable funds. In evaluating the costs of the services to be provided by BlackRock Advisors under the Fund's BlackRock Investment Advisory Agreement, each Fund's directors considered, among other things, whether advisory fees or other expenses would change as a result of the Transaction. Based on their review of the materials provided and the fact that the Fund's BlackRock Investment Advisory Agreement is substantially similar to the Fund's Previous Investment Advisory Agreement in all material respects, including the rate of compensation, each Fund's directors determined that the Transaction should not increase the total fees payable, including any fee waivers or after any expense caps or expense reimbursements, for advisory and administrative services. Each Fund's directors noted that it was not possible to predict how the Transaction would affect BlackRock Advisors' profitability from its relationship with the Fund. Each Fund's directors discussed with BlackRock Advisors its general methodology to be used in determining it's profitability with respect to its relationship with the Fund and noted that they expect to receive profitability information from BlackRock Advisors on at least an annual basis. Economies of Scale -- Each Fund's 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. The 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. Fall-Out Benefits -- The directors considered whether the Funds would generate any fall-out benefits to BlackRock Advisors. Fall-out benefits are indirect profits from other activities that accrue to the adviser or its affiliates solely because of the existence of the fund. In evaluating the fall-out benefits to be received by BlackRock Advisors under the Fund's BlackRock Investment Advisory Agreement, each Fund's directors considered whether BlackRock Advisors would experience such benefits to the same extent that the Previous Investment Adviser was experiencing such benefits under the Fund's Previous Investment Advisory Agreement. Based on their review of the materials provided, including materials received in connection with their most recent approval of the continuance of the Fund's Previous Investment Advisory Agreement, and their discussions with management of the Previous Investment Adviser and BlackRock, each Fund's directors determined that BlackRock Advisors' fall-out benefits could include increased ability for BlackRock to distribute shares of its funds and other investment products. The directors noted that any fall-out benefits were difficult to quantify with certainty. Investment Performance -- Each Fund's Board considered investment performance for the Fund. Each Fund's directors compared the Fund's performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of funds, and the performance of a relevant index or combination of indexes. The comparative information received from Lipper showed each Fund's performance at various levels within the range of performance of comparable funds over different time periods. Each Fund's directors believed the Fund's performance was satisfactory. Also, each Board took into account the investment performance of funds advised by BlackRock Advisors. Each Board considered comparative information from Lipper which showed that the performance of the funds advised by BlackRock Advisors was within the range of performance of comparable funds over different time periods. Each Fund's Board noted BlackRock's considerable investment management experience and capabilities, but was unable to predict 62 ANNUAL REPORTS OCTOBER 31, 2006 what effect, if any, consummation of the Transaction would have on the future performance of the Fund. Conclusion -- After the independent directors of each Fund deliberated in executive session, the Fund's entire Board, including the independent directors, approved the Fund's BlackRock Investment Advisory Agreement, concluding that the advisory fee rate was reasonable in relation to the services provided and that the BlackRock Investment Advisory Agreement was in the best interests of the shareholders. In approving the Fund's BlackRock Investment Advisory Agreement, each Fund's Board noted that it anticipated reviewing the continuance of the agreement in advance of the expiration of the initial two-year period. New BlackRock Sub-Advisory Agreements -- Matters Considered by the Boards At an in-person meeting held on August 22-23, 2006, each Fund's Board of Directors or Board of Trustees, as pertinent, including the independent directors, discussed and approved the Fund's sub-advisory agreement (each, a "BlackRock Sub-Advisory Agreement") between BlackRock Advisors and its affiliate, BlackRock Investment Management, LLC (the "Sub-Adviser"). Each Fund's BlackRock Sub-Advisory Agreement became effective on September 29, 2006, at the same time the Fund's BlackRock Investment Advisory Agreement became effective. Pursuant to each Fund's BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a monthly fee from BlackRock Advisors equal to 59% of the advisory fee received by BlackRock Advisors from the Fund. BlackRock Advisors pays the Sub-Adviser out of its own resources, and there is no increase in the expenses of any of the Funds as a result of the Funds' BlackRock Sub-Advisory Agreement. In approving the Funds' BlackRock Sub-Advisory Agreement at the August in-person meeting, each Fund's Board reviewed its considerations in connection with its approval of the Fund's BlackRock Investment Advisory Agreement in May 2006. Each Fund's Board relied on the same information and considered the same factors as those discussed above in connection with the approval of the Fund's BlackRock Investment Advisory Agreement, and came to the same conclusion. In reviewing the sub-advisory fee rate provided in each Fund's BlackRock Sub-Advisory Agreement, the Fund's Board noted the fact that both BlackRock Advisors and the Sub-Adviser have significant responsibilities under their respective advisory agreements. BlackRock Advisors remains responsible for oversight of each Fund's operations and administration, and the Sub-Adviser provides advisory services to the Fund and is responsible for the day-to-day management of the Fund's portfolio under the Fund's BlackRock Sub-Advisory Agreement. Each Fund's Board also took into account the fact that there is no increase in total advisory fees paid by the Fund as a result of the Fund's BlackRock Sub-Advisory Agreement. Under all of the circumstances, each Fund's Board concluded that it was a reasonable allocation of fees for the Sub-Adviser to receive 59% of the advisory fee paid by the Fund to BlackRock Advisors. After each Fund's independent directors deliberated in executive session, each Fund's entire Board, including the independent directors, approved the Fund's BlackRock Sub-Advisory Agreement, concluding that the sub-advisory fee was reasonable in relation to the services provided and that the BlackRock Sub-Advisory Agreement was in the best interests of shareholders.

The Plan is administered on behalf of the shareholders by The Bank of New York for BlackRock MuniYield Fund, Inc. and BlackRock MuniYield Quality Fund II, Inc. and Computershare Trust Company, N.A. for BlackRock MuniYield Insured Fund, Inc. and BlackRock MuniYield Quality Fund, Inc. (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.

Swensrud (retired as of December 31, 2005) 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 has delegated to the Manager authority to vote all proxies relating to the Fund's portfolio securities. The Manager has adopted policies and procedures (the "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 Manager'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 Manager 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 Manager considers the interests of its clients, including each Fund, and not the interests of the Manager, when voting proxies and that real (or perceived) material conflicts that may arise between the Manager's interest and those of the Manager's clients are properly addressed and resolved. In order to implement the Proxy Voting Procedures, the Manager has formed a Proxy Voting Committee (the "Committee"). The Committee, which is a subcommittee of the Manager's Equity Investment Policy Oversight Committee ("EIPOC"), is comprised of a senior member of the Manager's equity management group who is also a member of EIPOC, one or more other senior investment professionals appointed by EIPOC, portfolio managers and investment analysts appointed by EIPOC and any other personnel EIPOC deems appropriate. The Committee will also include two non-voting representatives from the Manager's Legal Department appointed by the Manager's General Counsel. The Committee's membership shall be limited to full-time employees of the Manager. No person with any investment banking, trading, retail brokerage or research responsibilities for the Manager'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 Manager 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 Manager 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 Manager 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 Manager 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 Manager 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 Manager will generally seek to vote proxies over which the Manager exercises voting authority in a uniform manner for all the Manager'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 Manager 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 Manager by ISS include in-depth research, voting recommendations (although the Manager 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 Manager's Proxy Voting Procedures also address special circumstances that can arise in connection with proxy voting. For instance, under the Proxy Voting Procedures, the Manager 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 Manager 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 Manager may be required to vote proxies in respect of an issuer where an affiliate of the Manager (each, an "Affiliate"), or a money management or other client of the Manager, including investment companies for which the Manager provides investment advisory, administrative and/or other services (each, a "Client"), is involved. The Proxy Voting Procedures and the Manager'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 Manager'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 Committee may pass the voting power to a subcommittee, appointed by EIPOC (with advice from the Secretary of the Committee), consisting solely of Committee members selected by EIPOC. EIPOC 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 Manager'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 Manager'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 Manager's normal voting guidelines or, on matters where the Manager'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 Manager 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 Manager's fiduciary duties. In addition to the general principles outlined above, the Manager 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 Manager 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 Manager has adopted specific voting guidelines with respect to the following proxy issues: o 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 number of other directorships, history of representing shareholder interests as a director of other companies or other factors, to the extent the Committee deems relevant. o 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. o 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. o 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. o 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. o Routine proposals related to requests regarding the formalities of corporate meetings. o 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, which the Investment Company Act envisions will be approved directly by shareholders. o 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, 2006. (a)(1) BlackRock MuniYield Insured Fund, Inc. is managed by a team of investment professionals comprised of William R. Bock, Director at BlackRock, Theodore R. Jaeckel, Jr., CFA, Managing Director at BlackRock, and Walter O'Connor, Managing Director at BlackRock. Each is a member of BlackRock's municipal tax-exempt management group.

BlackRock has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees and other potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, BlackRock furnishes investment management and advisory services to numerous clients in addition to the Fund, and BlackRock may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to BlackRock, or in which portfolio managers have a personal interest in the receipt of such fees), which may be the same as or different from those made to the Fund. In addition, BlackRock, its affiliates and any officer, director, stockholder or employee may or may not have an interest in the securities whose purchase and sale BlackRock recommends to the Fund. BlackRock, or any of its affiliates, or any officer, director, stockholder, employee or any member of their families may take different actions than those recommended to the Fund by BlackRock with respect to the same securities. Moreover, BlackRock may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock's (or its affiliates') officers, directors or employees are directors or officers, or companies as to which BlackRock or any of its affiliates or the officers, directors and employees of any of them has any substantial economic interest or possesses material non-public information. Each portfolio manager also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for the Fund. In this connection, it should be noted that certain portfolio managers currently manage certain accounts that are subject to performance fees. In addition, certain portfolio managers assist in managing certain hedge funds and may be entitled to receive a portion of any incentive fees earned on such funds and a portion of such incentive fees may be voluntarily or involuntarily deferred. Additional portfolio managers may in the future manage other such accounts or funds and may be entitled to receive incentive fees. As a fiduciary, BlackRock owes a duty of loyalty to its clients and must treat each client fairly. When BlackRock purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. BlackRock attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock has adopted a policy that is intended to ensure that investment opportunities are allocated fairly and equitably among client accounts over time. This policy also seeks to achieve reasonable efficiency in client transactions and provide BlackRock with sufficient flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base. (a)(3) As of October 31, 2006: Portfolio Manager Compensation The portfolio manager compensation program of BlackRock and its affiliates, including the Investment Adviser, is critical to BlackRock'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 certain BlackRock and its affiliates portfolio managers are a fixed base salary, annual performance-based cash and stock compensation (cash and stock bonus) and other benefits. BlackRock 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 BlackRock 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 BlackRock 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, certain BlackRock and its affiliates portfolio manager incentive compensation is based on a formulaic compensation program. BlackRock's formulaic portfolio manager compensation program includes: investment performance relative to a subset of general closed-end, insured, 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 the 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. All factors are considered collectively by BlackRock 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 BlackRock 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 BlackRock stock price performance. As such, the stock bonus aligns each portfolio manager's financial interests with those of BlackRock 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 BlackRock'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 certain BlackRock mutual funds (including their own funds) during a five-year vesting period. The deferred cash program aligns the interests of participating portfolio managers with the investment results of BlackRock 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 BlackRock employees, including broad-based retirement, 401(k), health, and other employee benefit plans. (a)(4) Beneficial Ownership of Securities. As of October 31, 2006, neither of Messrs. Bock, Jaeckel and O'Connor beneficially owns any stock issued by the Fund. Item 9 - Purchases of Equity Securities by Closed-End Management Investment Company and Affiliated Purchasers - Not Applicable Item 10 - Submission of Matters to a Vote of Security Holders - Not Applicable Item 11 - Controls and Procedures 11(a) - The Registrant's principal executive and principal financial officers have evaluated the Registrant's disclosure controls and procedures, including internal control over financial reporting, within 90 days of this filing. Such principal officers have concluded that the Registrant's disclosure controls and procedures were effective in design and operation to reasonably ensure that information required to be disclosed by the Registrant in this Form N-CSR was recorded, processed, summarized, and reported within the required time periods, and were sufficient to form the basis of the certifications required by Rule 30a-(2) of the Investment Company Act of 1940, as amended. Prior to reaching that conclusion, such principal officers had become aware of matters relating to the Registrant's participation in certain inverse floater structures that necessitated adjustments to financial information included in Item 1 of this filing. As a result, management of the Registrant has reevaluated certain disclosure controls and procedures determined not to be effective, as discussed more fully below. Management of the Registrant is responsible for establishing and maintaining effective internal control over financial reporting. In fulfilling this responsibility, estimates and judgments by management are required to assess the expected benefits and related costs of controls. The Registrant's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Such internal control includes policies and procedures that provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of a registrant's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A control deficiency exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. A significant deficiency is a control deficiency, or combination of control deficiencies, that adversely affects the Registrant's ability to initiate, authorize, record, process or report financial data reliably in accordance with generally accepted accounting principles such that there is more than a remote likelihood that a misstatement of the Registrant's annual or interim financial statements that is more than inconsequential will not be prevented or detected. A material weakness is a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Prior to the filing of this Form N-CSR, the Registrant identified the following control deficiency, that was determined to be a material weakness, as defined above, in the Registrant's internal control over financial reporting. The Registrant's controls related to the review and analysis of relevant terms and conditions of transfers of certain assets pertaining to inverse floater structures were not operating effectively to appropriately determine whether the transfers of assets qualified for sale accounting under the provisions of Statement of Financial Accounting Standards No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities" ("SFAS 140"). Accordingly, the Registrant's financial statements as of and for the period ended October 31, 2006, including prior periods where applicable, were adjusted prior to being issued to appropriately reflect transfers of such securities as secured borrowings and to report the related income and expense. These adjustments had no impact on net assets, net asset value per share or total return. Management of the Registrant believes that subsequent to the adjustments, the Registrant's accounting treatment of such transfers is appropriate under SFAS 140. Additionally, management of the Registrant is taking such further actions as are necessary to enhance its internal control over financial reporting, and in doing so, increase the effectiveness of such controls, so that such transfers of assets are reviewed and evaluated appropriately under the provisions of SFAS 140. 11(b) - There have been no changes in the Registrant's internal control over financial reporting (as defined in Rule 30a-3(d) under the Investment Company Act of 1940, as amended) that occurred during the second half of the Registrant's fiscal year that have materially affected, or are reasonably likely to materially affect, the Registrant's internal control over financial reporting. However, as discussed above, subsequent to October 31, 2006, the Registrant is further enhancing controls related to the application of SFAS 140.
