A Letter to Shareholders
Dear Shareholder
In its first four months, 2007 could already be termed an eventful year for
investors. For most financial markets, 2007 opened just as 2006 ended -- on a
positive trajectory. Then, at the end of February and into March, global equity
markets registered their first significant decline since last summer. The market
jitters were triggered by a significant setback in the Chinese market and were
exacerbated by worries of a weakening economy, escalating geopolitical concerns
and rising delinquencies in the subprime mortgage market. Still, underlying
stock market fundamentals appeared quite sound, supported by a generally
favorable global economic backdrop, tame inflation, slowing but still positive
earnings growth, relatively low interest rates and attractive valuations. These
conditions prevailed later, and the Dow Jones Industrial Average crossed the
13,000 mark for the first time in its history in late April.
Not unlike the equity market, the bond market also experienced volatility as
observers attempted to interpret mixed economic signals. A bond market rally
(falling yields and rising prices) late last year reversed itself early in 2007
amid some transitory signs of economic strength. Overall, yields have fluctuated
month to month but ended April little changed from the beginning of the year.
However, compared to one year ago, yields on 30-year Treasury bonds fell 36
basis points (.36%) and 10-year yields fell 44 basis points, while prices
correspondingly rose.
For its part, the Federal Reserve Board (the Fed) has left the target short-term
interest rate on hold at 5.25% since first pausing in its interest rate-hiking
campaign on August 8, 2006. The central bankers continue to express concern
about potential inflationary pressures, but also acknowledge signs of economic
weakness. Given this relatively "balanced" assessment, most observers believe
the Fed will keep interest rates on hold for now.
Against this backdrop, most major market indexes posted positive returns for the
annual and semi-annual reporting periods ended April 30, 2007:

A Discussion With Your Funds' Portfolio Managers
The Funds posted total returns that surpassed their respective Lipper
category averages for the period, as we maintained our focus on generating yield
and protecting net asset value.
Describe the recent market environment relative to municipal bonds.
Long-term bond yields traded in a fairly broad and volatile range over the past
six months, only to end the period little changed. Overall, financial conditions
have remained relatively balanced, with moderate economic activity and
well-contained inflationary pressures. Recent commentary from the Federal
Reserve Board (the Fed) has supported this trading range. The Fed is expected to
maintain its "balanced" economic assessment at least into mid-year.
During the six-month reporting period, 30-year U.S. Treasury bond yields rose
nine basis points (.09%) to 4.81%, while 10-year Treasury note yields rose two
basis points to 4.63%. Similarly, movements were fairly muted in the tax-exempt
market. As measured by Municipal Market Data, yields on AAA-rated municipal
bonds maturing in 30 years declined three basis points to 4.10%, and yields on
AAA-rated municipal bonds maturing in 10 years rose 12 basis points to 3.76%.
Investor demand for municipal product continued to strengthen throughout the
six-month period. The Investment Company Institute reports that long-term
municipal bond funds received over $8.7 billion in net new cash flows during the
first three months of 2007, a 42% increase compared to the first three months of
2006. Weekly fund flows, as reported by AMG Data, also have risen. Weekly
inflows during the three-month period ended April 30, 2007, averaged over $489
million, up from a weekly average of $400 million in fourth quarter 2006. The
improving demand among retail investors reflects, in large part, increased
acceptance of lower nominal yields and bond coupon structure. Throughout much of
last year, retail-oriented municipal bond broker/dealers noted significant
individual investor resistance to purchasing tax-exempt issues with yields below
4.50% and/or issues bearing nominal coupons below 5%. As tax-exempt bond yields
have stabilized in recent months, it appears retail investors have become
increasingly comfortable purchasing tax-exempt bonds with those characteristics,
which has served to support the market's performance.
In terms of supply, issuance of long-term municipal bonds has increased over the
past six months. More than $225 billion in new bonds was issued during the April
reporting period, an increase of over 30% compared to the same six months one
year ago. Over the past three months, municipalities issued more than $106
billion in new long-term tax-exempt bonds, an increase of more than 32% compared
to the same period a year ago. So far this year, greater than $135 billion in
long-term municipal bonds have been underwritten, putting 2007 annual issuance
some 4% ahead of 2005's record pace. Issuers have continued to take advantage of
historically low interest rates to refinance outstanding issues. In the first
four months of 2007, we have seen 10 underwritings exceeding $1 billion in size.
These "mega-deals" have continued to be relatively easily absorbed by market
participants, especially non-traditional and foreign buyers who find the
liquidity afforded by these deals to be particularly attractive.
Looking ahead, we believe investor demand will be critical in maintaining the
tax-exempt market's strong technical position. The increase in new bond supply
seen this year is unlikely to abate significantly, leading to record or
near-record annual issuance. Relatively stable yield ratios compared to taxable
bonds, coupled with a comparatively steep municipal yield curve, should help to
sustain traditional and non-traditional investor interest in tax-exempt bonds
and support the market's performance into mid-2007.
4 SEMI-ANNUAL REPORTS APRIL 30, 2007
BlackRock MuniYield Fund, Inc.
How did the Fund perform during the period?
For the six-month period ended April 30, 2007, the Common Stock of BlackRock
MuniYield Fund, Inc. had net annualized yields of 5.53% and 5.24%, based on a
period-end per share net asset value of $14.89 and a per share market price of
$15.71, respectively, and $.408 per share income dividends. Over the same
period, the total investment return on the Fund's Common Stock was +2.19%, based
on a change in per share net asset value from $14.98 to $14.89, and assuming
reinvestment of all distributions.
The Fund's total return, based on net asset value, exceeded the +1.66% average
return of the Lipper General Municipal Debt Funds (Leveraged) category for the
six-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
above-average dividend yield, which is largely the result of the portfolio's
exposure to lower-rated, higher-yielding credits. Another significant driver of
positive performance was the refunding activity that has been evident in the
market for some time. A number of the Fund's holdings were refunded during the
period and enjoyed subsequent increases in value. An additional benefit of the
refunding activity was a boost in the overall credit profile of the portfolio as
some of our lower-rated or non-rated bonds were refunded (when a bond is
refunded, the risk of default essentially drops to zero and, therefore, raises
the credit quality to the equivalent of a AAA-rated issue).
For the most part, the Fund's interest rate exposure remained neutral during the
six-month period and did not have a significant effect on performance. We did,
however, employ some tactical hedging strategies in order to position the Fund a
bit more defensively (that is, less interest rate exposure) late in the period.
This move was in anticipation of the temporary weakness typically seen in the
municipal market around the April tax deadline, when investors are focused more
on allocating funds for tax payments than on buying bonds. While the "tax
effect" was fairly muted this year, our hedging strategies did prove beneficial
to performance for the period. On the negative side, a widening in credit
spreads in the health care industry was a detractor, although the Fund's neutral
exposure to that sector limited its influence on overall performance.
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 distributions, 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?
In our last report to shareholders, we noted that portfolio activity had been
focused on taking advantage of further flattening in the municipal yield curve
by shifting assets to the 10-year to 15-year area of the curve. During the most
recent six months, we made only modest efforts to pursue this strategy as we
came to believe that the yield curve will potentially maintain its flatness for
an extended period of time. While we still see the greatest value in the 10-year
to 15-year part of the curve, we also foresee continued strength on the long end
due, in part, to high demand from traditional investors who are drawn to the
positively sloped municipal curve versus other asset classes. Additionally,
issuers have lately become more inclined to raise capital through structured
derivative products rather than traditional bonds. Should investor demand for
structured products remain strong, the supply of long-term fixed rate bonds may
be reduced, which would lend further strength to the long end of the curve.
Other activity during the six-month period included an effort to increase
exposure to the high-grade housing and health care sectors as part of our larger
goal of upgrading the overall credit profile of the portfolio. As heavy issuance
occurred in both sectors, bond prices declined and we found attractive values on
high-grade issues (AA or AAA). Given the persistently narrow credit spreads of
these sectors and the added incentive of reduced prices on high-grade credits,
we were able to increase the quality of the portfolio with less yield loss than
is typically associated with a credit upgrade.
SEMI-ANNUAL REPORTS APRIL 30, 2007 5
A Discussion With Your Funds' Portfolio Managers (continued)
For the six-month period ended April 30, 2007, the Fund's Auction Market
Preferred Stock had average yields of: 3.50% for Series A, 3.65% for Series B,
3.45% for Series C, 3.40% for Series D, 3.55% for Series E, 3.53% for Series F
and 3.52% for Series G. The Fed opted to keep the target short-term interest
rate on hold at 5.25% throughout the period. As such, the Fund's borrowing costs
were stable, but relatively high during the period as we experienced a typical
spike related to the April tax-filing deadline. The municipal yield curve,
although flat by historical standards, remained positively sloped and continued
to generate an income benefit to the Common Stock shareholder from the
leveraging of Preferred Stock. As always, 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,
as it appears that the Fed will refrain from changing its target short-term
interest rate for some time. When we see more definite signs that the economy is
indeed continuing to slow to the point where the Fed is likely to lower rates,
we will look to adjust the portfolio to take advantage of the falling-rate
environment. We also intend to continue working on reducing the portfolio's
credit exposure while maintaining the competitive income to shareholders that
the Fund has consistently achieved for several years. At period-end, our
borrowing costs were still elevated due to the seasonal spike associated with
tax season, but we expect rates to settle back rather quickly and allow us more
flexibility to pursue our credit strategies.
BlackRock MuniYield Insured Fund, Inc.
How did the Fund perform during the period?
For the six-month period ended April 30, 2007, the Common Stock of BlackRock
MuniYield Insured Fund, Inc. had net annualized yields of 4.45% and 4.73%, based
on a period-end per share net asset value of $15.22 and a per share market price
of $14.33, respectively, and $.336 per share income dividends. Over the same
period, the total investment return on the Fund's Common Stock was +1.85%, based
on a change in per share net asset value from $15.30 to $15.22, and assuming
reinvestment of all distributions.
The Fund's total return, based on net asset value, exceeded the +1.46% average
return of the Lipper Insured Municipal Debt Funds (Leveraged) category for the
six-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 our long duration relative to our peers, a
posture we assumed for the majority of the period. Rates moved within a very
narrow range during the period, but our slightly long bias proved favorable at
times when the market rallied (that is, rates fell and prices increased). This
was particularly true toward the end of 2006.
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 distributions, 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.
6 SEMI-ANNUAL REPORTS APRIL 30, 2007
What changes were made to the portfolio during the period?
While we generally favored a long duration, we shifted to a slightly short bias
in January and February in anticipation of a market decline. We refocused our
efforts on increasing duration in March and April based on our belief that
turmoil in the subprime mortgage market would bring yields down. Throughout the
six months, we aimed to achieve additional yield for the portfolio by investing
in longer-dated bonds, specifically in the 25-year to 30-year maturity range,
while also seeking to protect the Fund's underlying value.
In our last report to shareholders, we noted a marked narrowing of credit
spreads between municipal bonds issued by high-tax states and those issued by
low-tax states. In seeking to capitalize on this trend, we looked 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 maintained
that bias during this period, especially with regard to California issues, in
which we maintained a position of approximately 23% of net assets.
Similarly, we maintained the Fund's exposure to the Pacific Northwest, where we
continue to observe solid credit fundamentals. Bonds issued by the State of
Washington made up approximately 10% of the portfolio.
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 April 30, 2007, the Fund's Auction Market
Preferred Stock had average yields of 3.50% for Series A, 3.60% for Series B,
3.64% for Series C, 3.49% for Series D, 3.51% for Series E, 3.63% for Series F,
3.56% for Series G, 3.55% for Series H and 3.55% for Series I. The Fed kept its
target interest rate unchanged during the six-month period at 5.25%. As such,
the Fund's borrowing costs remained relatively stable. Importantly, the
municipal yield curve maintained its positive slope, particularly compared to
the Treasury curve, and continued to generate an income benefit to the Common
Stock shareholder from the leveraging of Preferred Stock. As always, should the
spread between short-term and long-term interest rates narrow, the benefits of
leveraging will decline and, as a result, reduce the yield available to the
Common Stock shareholder. (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 neutral to 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 to 30-year area and to favor a
neutral to slightly long portfolio duration, which offers the benefit of
incremental yield. We believe above-average yields can provide for competitive
Fund returns over time.
SEMI-ANNUAL REPORTS APRIL 30, 2007 7
A Discussion With Your Funds' Portfolio Managers (continued)
BlackRock MuniYield Quality Fund, Inc.
How did the Fund perform during the period?
For the six-month period ended April 30, 2007, the Common Stock of BlackRock
MuniYield Quality Fund, Inc. had net annualized yields of 4.53% and 4.79%, based
on a period-end per share net asset value of $15.21 and a per share market price
of $14.39, respectively, and $.342 per share income dividends. Over the same
period, the total investment return on the Fund's Common Stock was +1.69%, based
on a change in per share net asset value from $15.32 to $15.21, and assuming
reinvestment of all distributions.
The Fund's total return, based on net asset value, outpaced the +1.46% average
return of the Lipper Insured Municipal Debt Funds (Leveraged) category for the
six-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 positive performance is primarily attributed to two factors. First,
in prior periods, we had focused on investing further out along the municipal
yield curve, a strategy that continued to benefit performance as longer-dated
bonds outperformed issues with shorter maturities during this period (that is,
the yield curve flattened). Second, several bond holdings were advance refunded
during the period, which also proved advantageous. When bonds are refunded ahead
of their maturity date, they generally rise sharply in value. Finally, it is
worth noting that the Fund's relatively neutral status in terms of duration (a
measure of interest rate sensitivity) provided an incremental advantage versus
our peers that had taken a more severe bias in terms of the direction of
interest rates. Overall, interest rates were volatile but little changed over
the course of the period.
For a description of the Fund's total investment return based on a change in the
per share market value of the Fund's Common 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?
We maintained the Fund's fully invested stance and relatively neutral posture on
interest rate risk. In terms of specific portfolio activity during the period,
we sold some recently advance refunded positions, as their book yields were not
significantly above current market yields, and moved into higher-yielding
current issues. In doing so, we focused on bonds that could be advance refunded
in the future, primarily premium-coupon, high-quality bonds in the 15-year to
20-year maturity range, which would allow us to replicate the same types of
trades again (that is, sell bonds with lower yields in exchange for bonds with
higher yields as the curve steepens).
The Fund has the ability to invest in bonds that are not insured, and we made
use of that uninsured basket in an effort to enhance yield in the portfolio. Of
course, "uninsured" does not necessarily mean substantially lower quality. In
many cases, uninsured bonds are AAA-rated due to other types of enhancements. As
such, our use of the uninsured basket did not translate into a meaningful drop
in the Fund's credit quality.
8 SEMI-ANNUAL REPORTS APRIL 30, 2007
We had ample opportunity to add single-family housing bonds and health
care-related issues to the portfolio given heavy issuance in the two sectors
during the period. In both cases, yields were more attractive than they had been
in the past couple of years. The single-family housing bonds are generally rated
AA or AAA, even without insurance. In the health care sector, we primarily found
opportunities in A-rated and AA-rated hospital issues. So, again, we were able
to take advantage without a huge sacrifice in terms of credit quality.
For the six-month period ended April 30, 2007, the Fund's Auction Market
Preferred Stock had average yields of 3.67% for Series A, 3.55% for Series B,
3.53% for Series C, 3.61% for Series D and 3.55% for Series E. The Fed kept its
target interest rate unchanged during the six-month period at 5.25%. As such,
the Fund's borrowing costs remained relatively stable. Importantly, the
municipal yield curve maintained its positive slope, particularly compared to
the Treasury curve, and continued to generate an income benefit to the Common
Stock shareholder from the leveraging of Preferred Stock. As always, should the
spread between short-term and long-term interest rates narrow, the benefits of
leveraging will decline and, as a result, reduce the yield available to the
Common Stock shareholder. (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?
The Fund ended the period in a neutral position with respect to interest rate
risk. We believe this is the appropriate posture with the Fed on hold and given
the historical flatness of the yield curve. We will look for a steepening of the
yield curve to provide attractive investment opportunities for the portfolio. In
particular, we believe the 15-year to 20-year area of the curve could offer
strong relative performance in the future.
The Fund was fully invested at period-end, reflecting our efforts to enhance
tax-free income for our shareholders. Overall, we maintain our focus on
providing shareholders with a competitive yield and preservation of net asset
value within the context of a high-quality portfolio.
BlackRock MuniYield Quality Fund II, Inc.
How did the Fund perform during the period?
For the six-month period ended April 30, 2007, the Common Stock of BlackRock
MuniYield Quality Fund II, Inc. had net annualized yields of 4.46% and 4.77%,
based on a period-end per share net asset value of $13.55 and a per share market
price of $12.67, respectively, and $.300 per share income dividends. Over the
same period, the total investment return on the Fund's Common Stock was +1.76%,
based on a change in per share net asset value from $13.64 to $13.55, and
assuming reinvestment of all distributions.
The Fund's total return, based on net asset value, outpaced the +1.46% average
return of the Lipper Insured Municipal Debt Funds (Leveraged) category for the
six-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 positive performance is primarily attributed to two factors. First,

A Discussion With Your Funds' Portfolio Managers (concluded)
What changes were made to the portfolio during the period?
We maintained the Fund's fully invested stance and relatively neutral posture on
interest rate risk. In terms of specific portfolio activity during the period,
we sold some recently advance refunded positions, as their book yields were not
significantly above current market yields, and moved into higher-yielding
current issues. In doing so, we focused on bonds that could be advance refunded
in the future, primarily premium-coupon, high-quality bonds in the 15-year to
20-year maturity range, which would allow us to replicate the same types of
trades again (that is, sell bonds with lower yields in exchange for bonds with
higher yields as the curve steepens).
The Fund has the ability to invest in bonds that are not insured, and we made
use of that uninsured basket in an effort to enhance yield in the portfolio. Of
course, "uninsured" does not necessarily mean substantially lower quality. In
many cases, uninsured bonds are AAA-rated due to other types of enhancements. As
such, our use of the uninsured basket did not translate into a meaningful drop
in the Fund's credit quality.
We had ample opportunity to add single-family housing bonds and health
care-related issues to the portfolio given heavy issuance in the two sectors
during the period. In both cases, yields were more attractive than they had been
in the past couple of years. The single-family housing bonds are generally rated
AA or AAA, even without insurance. In the health care sector, we primarily found
opportunities in A-rated and AA-rated hospital issues. So, again, we were able
to take advantage without a huge sacrifice in terms of credit quality.
For the six-month period ended April 30, 2007, the Fund's Auction Market
Preferred Stock had average yields of 3.64% for Series A, 3.60% for Series B,
3.55% for Series C and 3.57% for Series D. The Fed kept its target interest rate
unchanged during the six-month period at 5.25%. As such, the Fund's borrowing
costs remained relatively stable. Importantly, the municipal yield curve
maintained its positive slope, particularly compared to the Treasury curve, and
continued to generate an income benefit to the Common Stock shareholder from the
leveraging of Preferred Stock. As always, should the spread between short-term
and long-term interest rates narrow, the benefits of leveraging will decline
and, as a result, reduce the yield available to the Common Stock shareholder.
(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?
The Fund ended the period in a neutral position with respect to interest rate
risk. We believe this is the appropriate posture with the Fed on hold and given
the historical flatness of the yield curve. We will look for a steepening of the
yield curve to provide attractive investment opportunities for the portfolio. In
particular, we believe the 15-year to 20-year area of the curve could offer
strong relative performance in the future.
The Fund was fully invested at period-end, reflecting our efforts to enhance
tax-free income for our shareholders. Overall, we maintain our focus on
providing shareholders with a competitive yield and preservation of net asset
value within the context of a high-quality portfolio.

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 April 30, 2007, BlackRock MuniYield Fund, Inc., BlackRock MuniYield
Insured Fund, Inc., BlackRock MuniYield Quality Fund, Inc. and BlackRock
MuniYield Quality Fund II, Inc. had leverage amounts, due to Auction Market
Preferred Stock, of 33.85%, 35.75%, 35.07% and 34.55% 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 (Unaudited)
1. Significant Accounting Policies:
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"), are registered under the
Investment Company Act of 1940, as amended, as non-diversified, closed-end
management investment companies. The Funds' financial statements are prepared in
conformity with U.S. generally accepted accounting principles, which may require
the use of management accruals and estimates. Actual results may differ from
these estimates. These unaudited financial statements reflect all adjustments,
which are, in the opinion of management, necessary to present a fair statement
of the results for the interim period. All such adjustments are of a normal,
recurring nature. The Funds determine and make available for publication the net
asset value of their Common Stock 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. Effective April 2, 2007, short-term securities
purchased with a maturity of greater than 60 days may be valued at amortized
cost. 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.
(b) Derivative financial instruments -- Each Fund may engage in various
portfolio investment strategies both to increase the return of the Fund and to
hedge, or protect, its exposure to interest rate movements and movements in the
securities markets. Losses may arise due to changes in the value of the contract
due to an unfavorable change in the price of the underlying security or if the
counterparty does not perform under the contract. The counterparty for certain
instruments may pledge cash or securities as collateral.
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.
SEMI-ANNUAL REPORTS APRIL 30, 2007 45
Notes to Financial Statements (continued)
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, 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 April 30, 2007, the aggregate
value of the underlying municipal securities transferred to TOBs and the
liability for trust certificates were:
--------------------------------------------------------------------------------
Underlying
Municipal
Liability Range of Bonds
for Trust Interest Transferred
Certificates Rates to TOBs
--------------------------------------------------------------------------------
BlackRock
MuniYield
Fund, Inc. ........ $ 36,112,500 3.95% - 3.98% $ 77,803,233
BlackRock
MuniYield Insured
Fund, Inc. ........ $182,665,000 3.92% - 4.02% $390,354,034
BlackRock
MuniYield Quality
Fund, Inc. ........ $ 79,897,914 3.95% - 4.02% $169,499,155
BlackRock
MuniYield Quality
Fund II, Inc. ..... $ 50,510,000 3.91% - 4.02% $106,455,776
--------------------------------------------------------------------------------
Financial transactions executed through TOBs generally will underperform 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
investments 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
Funds' net asset values 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 substan-
46 SEMI-ANNUAL REPORTS APRIL 30, 2007
Notes to Financial Statements (continued)
tially 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.
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
the last net asset value calculation in the first required financial statement
reporting period 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 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. At this time, management is evaluating the implications of FAS 157
and its impact on each of the Fund's financial statements, if any, has not been
determined.
In addition, in February 2007, FASB issued "Statement of Financial Accounting
Standards No. 159, The Fair Value Option for Financial Assets and Financial
Liabilities" ("FAS 159"), which is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157. FAS 159 permits entities to choose to
measure many financial instruments and certain other items at fair value that
are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. At this time, management is evaluating
the implications of FAS 159 and its impact on each of the Fund's financial
statements, if any, has not been determined.
2. Investment Advisory Agreement and Transactions with Affiliates:
The Investment Advisory Agreement between each Fund and BlackRock Advisors, LLC
(the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc. became
effective on September 29, 2006. Prior to September 29, 2006, Fund Asset
Management, L.P. ("FAM") was the Funds' manager. The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of
Merrill Lynch & Co., Inc. ("Merrill Lynch"), which is the limited partner.
Merrill Lynch and The PNC Financial Services Group, Inc. are principal owners of
BlackRock, Inc.
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 has
agreed to reimburse its management fee by the amount of management fees each
Fund pays to the Manager indirectly through its investment in the Black Rock
Institutional Tax-Exempt Fund. The reimbursements were as follows:
