A Letter to Shareholders

Dear Shareholder

Ten months into 2006, we are able to say it has been an interesting year for
investors. 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:

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. For additional insight and timely "food for
thought" for investors, we also invite you to visit Shareholder magazine at

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,

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.

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.

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.

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.

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:

================================================================================

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. Investment Advisory Agreement and Transactions with Affiliates:

On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. ("MLIM") and its affiliates, including Fund Asset
Management, L.P. ("FAM"), with BlackRock, Inc. to create a new independent
company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest
in the combined company and The PNC Financial Services Group, Inc. has
approximately a 34% economic and voting interest. The new company operates under
the BlackRock name and is governed by a board of directors with a majority of
independent members.

On August 15, 2006, shareholders of each Fund approved a new Investment Advisory
Agreement with BlackRock Advisors, Inc. (the "Manager"), an indirect, wholly
owned subsidiary of BlackRock, Inc. BlackRock Advisors, Inc. was recently
reorganized into a limited liability company and renamed BlackRock Advisors,
LLC. The new Investment Advisory Agreement between each Fund and the Manager
became effective on September 29, 2006. Prior to September 29, 2006, FAM was the
Investment Adviser. The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the
limited partner.

The Manager is responsible for the management of each of the Fund's portfolios
and provides the necessary personnel, facilities, equipment and certain other
services necessary to

the operations of each Fund. For such services, each Fund pays a monthly fee at
an annual rate of .50% of the Fund's average daily net assets, including
proceeds from the issuance of Preferred Stock. The Manager (and formerly FAM)
has agreed to reimburse its management fee by the amount of management fees each
Fund pays to the Manager and/or FAM indirectly through its investment in the
Merrill Lynch Institutional Tax-Exempt Fund. The reimbursements were as follows:

6. 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.

Notes to Financial Statements (concluded)

While the Statements of Net Assets for each of the Funds as of October 31, 2005,
2004, 2003 and 2002, not presented herein, have not been reissued to give effect
to the restatement, the principal effects of the restatement would be to
increase investments and liability for trust certificates by corresponding
amounts at each year end, with no effect on previously reported net assets.

The Statements of Operations for each of the Funds for the years ended October
31, 2005, 2004, 2003 and 2002, not presented herein, have not been reissued to
give effect to the restatement. However, the principal effects of the
restatement would be to increase interest income and interest expense and fees
by corresponding amounts each year, and, where applicable, to revise realized
gain (loss) on investments -- net, and the change in unrealized
appreciation/depreciation on investments -- net, by corresponding and offsetting

The Statements of Changes in Net Assets for each of the Funds for the years
ended October 31, 2004, 2003 and 2002, not presented herein, have not been
reissued to give effect to the restatement, but the principal effects of a
restatement, where applicable, would be to revise previously reported realized
gain (loss) -- net, and change in unrealized appreciation/depreciation-net, by
corresponding and offsetting amounts.


50              ANNUAL REPORTS                      OCTOBER 31, 2006


Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of BlackRock MuniYield Fund, Inc.,
BlackRock MuniYield Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc.
and BlackRock MuniYield Quality Fund II, Inc.:

We have audited each of the accompanying statements of net assets, including the
schedules of investments, of BlackRock MuniYield Fund, Inc. (formerly MuniYield
Fund, Inc.), BlackRock MuniYield Quality Fund, Inc. (formerly MuniYield Quality
Fund, Inc.), and BlackRock MuniYield Quality Fund II, Inc. (formerly MuniYield
Quality Fund II, Inc.), as of October 31, 2006, and the related statements of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, the financial highlights for
each of the five years in the period then ended for each of the respective
funds, and the statements of cash flows of BlackRock MuniYield Quality Fund,
Inc. and BlackRock MuniYield Quality Fund II, Inc. for the year then ended. We
have also audited the accompanying statement of net assets, including the
schedule of investments, of BlackRock MuniYield Insured Fund, Inc. (formerly
MuniYield Insured Fund, Inc.) as of October 31, 2006, and the related statements
of operations, changes in net assets and the financial highlights for the year
then ended. The above- referenced funds are hereinafter referred to collectively
as the "Funds." These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on the financial statements and financial highlights of each of the
funds based on our audits. The statement of changes in net assets of BlackRock
MuniYield Insured Fund, Inc. for the year ended October 31, 2005 (before the
restatement described in Note 6) and its financial highlights for each of the
four years in the period ended October 31, 2005 (before the restatement
described in Note 6) were audited by other auditors whose report, dated December
9, 2005, expressed a qualified opinion on that financial statement and financial
highlights because of the errors described in Note 6.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Funds
are not required to have, nor were we engaged to perform, audits of their
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Funds' internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of October 31, 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.

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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of MuniYield Insured Fund, Inc.:

We have audited, before the effects of the adjustments for the correction of the
error described in Note 6, the accompanying statement of changes in net assets
of MuniYield Insured Fund, Inc., for the year ended October 31, 2005, and
financial highlights for each of the four years in the period then ended (the
2005 financial statement and financial highlights referred to above before the
effects of the adjustments discussed in Note 6 are not presented herein). This
financial statement and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on this financial
statement and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's 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 Fund's 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 and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, except for the error described in Note 6, the 2005 financial
statement and financial highlights referred to above present fairly, in all
material respects, the changes in net assets of MuniYield Insured Fund, Inc. for
the year ended October 31, 2005, and the financial highlights for each of the
four years in the period then ended, in conformity with U.S. generally accepted
accounting principles.

We were not engaged to audit, review, or apply any procedures to the adjustments
for the correction of the error described in Note 6 and, accordingly, we do not
express an opinion or any other form of assurance about whether such adjustments
are appropriate and have been properly applied. Those adjustments were audited
by Deloitte & Touche LLP.

Change in Fund's Independent Registered Public Accounting Firm

On August 28, 2006, Ernst & Young llp ("E&Y) resigned as the Independent
Registered Public Accounting Firm of BlackRock MuniYield Insured Fund, Inc. (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).

The Audit Committee of the Fund's Board of Directors approved the engagement of

Firm for the fiscal year ended October 31, 2006.

Disclosure of Investment Advisory Agreement

Disclosure of FAM Investment Advisory Agreements

The Board of Directors of each Fund met in August 2006 to consider approval of
the Fund's investment advisory agreement with Fund Asset Management, L.P.
("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.

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.

Automatic Dividend Reinvestment Plan

How the Plan Works -- The Funds offer a Dividend Reinvestment Plan (the "Plan")
under which income and capital gains dividends paid by each Fund are
automatically reinvested in additional shares of Common Stock of each Fund. The
Plan is administered on behalf of the shareholders by The Bank of New York for
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. Box 11258, New York, NY 10286-1258,

Dividend Policy

The Funds' dividend policy is to distribute all or a portion of their net

at times pay out less than the entire amount of net investment income earned in
any particular month and may at times in any month pay out such accumulated but
undistributed income in addition to net investment income earned in that month.
As a result, the dividends paid by the Funds for any particular month may be
more or less than the amount of net investment income earned by the Funds during
such month. The Funds' current accumulated but undistributed net investment
income, if any, is disclosed in the Statement of Assets, Liabilities and
Capital, which comprises part of the Financial Information included in this
report.

These reports, including the financial information herein, are transmitted to
shareholders of BlackRock MuniYield Fund, Inc., BlackRock MuniYield Insured
Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock MuniYield

performance results shown in these reports should not be considered a
representation of future performance. The Funds have leveraged their Common
Stock and intend to remain leveraged by issuing Preferred Stock to provide the
Common Stock shareholders with potentially higher rates of return. Leverage
creates risks for Common Stock shareholders, including the likelihood of greater
volatility of net asset value and market price of shares of the Common Stock,
and the risk that fluctuations in the short-term dividend rates of the Preferred
Stock may affect the yield to Common Stock shareholders. Statements and other
information herein are as dated and are subject to change.

         (e)(1) The registrant's audit committee (the "Committee") has adopted
         policies and procedures with regard to the pre-approval of services.
         Audit, audit-related and tax compliance services provided to the
         registrant on an annual basis require specific pre-approval by the
         Committee. The Committee also must approve other non-audit services

         registrant's affiliated service providers that relate directly to the
         operations and the financial reporting of the registrant. Certain of
         these non-audit services that the Committee believes are a) consistent
         with the SEC's auditor independence rules and b) routine and recurring
         services that will not impair the independence of the independent
         accountants may be approved by the Committee without consideration on a
         specific case-by-case basis ("general pre-approval"). However, such
         services will only be deemed pre-approved provided that any individual
         project does not exceed $5,000 attributable to the registrant or
         $50,000 for all of the registrants the Committee oversees. Any proposed
         services exceeding the pre-approved cost levels will require specific
         pre-approval by the Committee, as will any other services not subject
         to general pre-approval (e.g., unanticipated but permissible services).
         The Committee is informed of each service approved subject to general
         pre-approval at the next regularly scheduled in-person board meeting.

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.

         in the Fund's portfolio during the most recent 12 month period ended
         October 31 is available without charge (1) at www.blackrock.com and (2)

         (iv) Potential Material Conflicts of Interest

         BlackRock has built a professional working environment, firm-wide
         compliance culture and compliance procedures and systems designed to



         protect against potential incentives that may favor one account over
         another. 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, leveraged,
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. Kalinoski and O'Connor beneficially owns any stock
             issued by the Fund. Mr. Jaeckel beneficially owns stock issued by
             the Fund in the range of $1 - $10,000.

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.
