2 ANNUAL REPORT JULY 31, 2009

Dear Shareholder

The past 12 months reveal two distinct market backdrops — one of extreme investor pessimism and decided weakness, and another of cautious optimism

and nascent signs of recovery. The first half of the period was characterized by the former, as the global financial crisis erupted into the worst recession

in decades. Daily headlines recounted universal macroeconomic deterioration, financial sector casualties, volatile swings in global equity markets, and

unprecedented government intervention that included widespread (and globally coordinated) monetary and quantitative easing by central banks and large-

scale fiscal stimuli. Sentiment improved noticeably in March 2009, however, on the back of new program announcements by the US Treasury Department

and Federal Reserve, as well as generally stronger-than-expected economic data in a few key areas, including retail sales, business and consumer confidence,

manufacturing and housing.

In this environment, US equities contended with extraordinary volatility, posting steep declines through mid-March 2009 before going on a three-month

rally that largely negated year-to-date losses. Late in the period, investor enthusiasm waned and a correction ensued for several weeks, mostly as a result

of profit taking and portfolio rebalancing, as opposed to a change in the economic outlook. Equities rallied once again as the period drew to a close, result-

ing in positive year-to-date returns for all major indexes. The experience in international markets was similar to that in the United States, though performance

was generally more extreme both on the decline and on the upturn. Notably, emerging markets, which lagged most developed regions through the downturn,

reassumed leadership in 2009 as these areas of the globe have generally seen a stronger acceleration in economic recovery.

In fixed income markets, while the flight to quality remained a prevalent theme, relatively attractive yields and distressed valuations, alongside a more

favorable macro environment, eventually captured investor attention, leading to a sharp recovery in non-Treasury assets. This has been particularly evident

in the high yield sector, which has firmly outpaced all other taxable asset classes since the start of 2009. At the same time, the municipal bond market

enjoyed a strong return after the exceptional market volatility of 2008, buoyed by a combination of attractive valuations, robust retail investor demand and

a slowdown in forced selling. Direct aid to state and local governments via the American Recovery and Reinvestment Act of 2009 has also lent support

to municipal bonds.

Total Returns as of July 31, 2009  6-month  12-month 
US equities (S&P 500 Index)  21.18%  (19.96)%

The market environment has clearly improved since the beginning of the year, but a great deal of uncertainty and risk remain. Through periods of market tur-

bulence, as ever, BlackRock’s full resources are dedicated to the management of our clients’ assets. For additional insight and timely “food for thought,” we

invite you to visit our award-winning Shareholder® magazine, now available exclusively online at www.blackrock.com/shareholdermagazine. We thank you

for entrusting BlackRock with your investments, and we look forward to continuing to serve you in the months and years ahead.


Announcement to Shareholders

On June 16, 2009, BlackRock, Inc. announced that it received written notice from Barclays PLC (“Barclays”) in which Barclays’ Board of Directors had

accepted BlackRock’s offer to acquire Barclays Global Investors (“BGI”). At a special meeting held on August 6, 2009, BlackRock’s proposed purchase of

BGI was approved by an overwhelming majority of Barclays’ voting shareholders, an important step toward closing the transaction. The combination of

BlackRock and BGI will bring together market leaders in active and index strategies to create the preeminent asset management firm. The transaction is

scheduled to be completed in the fourth quarter of 2009, subject to important fund shareholder and regulatory approvals.

Fund Summary as of July 31, 2009 BlackRock Muni New York Intermediate Duration Fund, Inc.

Investment Objective

BlackRock Muni New York Intermediate Duration Fund, Inc. (MNE) (the “Fund”) seeks to provide shareholders with high current income exempt from fed-
eral income taxes and New York State and New York City personal income taxes by investing primarily in a portfolio of municipal obligations, the interest on
which, in the opinion of bond counsel to the issuer, is exempt from federal income taxes and New York State and New York City personal income taxes. No
assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the 12 months ended July 31, 2009, the Fund returned 1.79% based on market price and 2.26% based on net asset value (“NAV”). For the same period,
the closed-end Lipper Intermediate Municipal Debt Funds category posted an average return of 6.93% based on market price and 2.06% on a NAV basis.
All returns reflect reinvestment of dividends. The Fund’s discount to NAV, which widened during the period, accounts for the difference between performance
based on price and performance based on NAV. During the period, the Fund’s distribution rate improved to roughly average for the peer group. Total return
reflected a combination of the Fund’s underperformance in the volatile fixed income markets through 2008, and its outperformance during the remarkable
recovery in risk assets — and return of the municipal market to more normal demand metrics — through the first half of 2009. During the period, we identified
sectors and credits that we were comfortable holding despite underperformance in the short term; these included some high yield credits, in addition to
Puerto Rico and housing bonds. Each of these segments ultimately benefited the Fund, as they outperformed during the market’s recovery. We also actively
participated in the new-issue market. Where possible, we focused on both longer-dated maturities permitted by the Fund’s intermediate duration mandate,
as well as discount coupon bonds to benefit from the increased demand from the retail sector.

4 ANNUAL REPORT JULY 31, 2009

Fund Summary as of July 31, 2009 BlackRock MuniYield Arizona Fund, Inc.

Investment Objective

BlackRock MuniYield Arizona Fund, Inc. (MZA) (the “Fund”) seeks to provide shareholders with as high a level of current income exempt from federal
and Arizona income taxes as is consistent with its investment policies and prudent investment management by investing primarily in a portfolio of long-term,
investment grade municipal obligations, the interest on which, in the opinion of bond counsel to the issuers, is exempt from federal and Arizona income taxes.
No assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the 12 months ended July 31, 2009, the Fund returned (1.66)% based on market price and 3.27% based on NAV. For the same period, the closed-end
Lipper Other States Municipal Debt Funds category posted an average return of 4.52% based on market price and 3.12% on a NAV basis. All returns reflect
reinvestment of dividends. The Fund’s premium to NAV, which narrowed during the period, accounts for the difference between performance based on price and
performance based on NAV. The benefit of above average yield is reflected in the total return of the portfolio. This is a product of the yield of the securities held
within the portfolio. During the first half of the period, performance was hindered by above-average exposure to the longer end of the yield curve, where yields
rose. Above-average exposure to lower-rated credits and other spread sectors, such as housing bonds, also hurt performance. The spread between high-grade
and lower-rated credits generally widened during the first half of the period, as credit markets adjusted to higher perceived risks and an overall weaker economy.
Fortunately, during the second half of the period, both of these factors reversed course and benefited the Fund. The yield curve flattened and credit spreads gen-
erally narrowed. Throughout the period, we worked to upgrade credit quality, when practical, in an often very volatile and illiquid market.Additionally, we favored
moving in the curve opportunistically. During the 12 months, Fund management maintained high cash allocations in an effort to reduce volatility and ensure that
ample cash was available to take advantage of opportunities in the new-issue market. The Fund’s cash balance lowered portfolio duration, which was beneficial;
however, it also held the yield down slightly as the money was invested in lower-yielding short-term investments, a negative factor.

Fund Summary as of July 31, 2009 BlackRock MuniYield California Fund, Inc.

Investment Objective

BlackRock MuniYield California Fund, Inc. (MYC) (the “Fund”) seeks to provide shareholders with as high a level of current income exempt from federal
and California income taxes as is consistent with its investment policies and prudent investment management by investing primarily in a portfolio of long-
term municipal obligations, the interest on which, in the opinion of bond counsel to the issuer, is exempt from federal and California income taxes. No
assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the 12 months ended July 31, 2009, the Fund returned 1.37% based on market price and 4.64% based on NAV. For the same period, the closed-end
Lipper California Municipal Debt Funds category posted an average return of (3.92)% based on market price and (5.13)% on a NAV basis. All returns reflect
reinvestment of dividends. The Fund’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and
performance based on NAV. The Fund’s duration positioning was neutral for most of the period. The majority of the Fund’s outperformance was derived from a
tightening in credit spreads. Along with extremely attractive borrowing costs, the portfolio accrual permitted an increase in dividends in June. Our strategy is to
pursue a balanced approach to returns, continue to bolster current yield and commit cash reserves when appropriate opportunities are uncovered. Credit fun-
damentals warrant monitoring in the current weak economic environment, especially in California, considering budgetary challenges. We are alert to improve
quality as opportunities arise.

Fund Summary as of July 31, 2009 BlackRock MuniYield Investment Fund

Investment Objective

BlackRock MuniYield Investment Fund (MYF) (the “Fund”) seeks to provide shareholders with as high a level of current income exempt from federal income
taxes as is consistent with its investment policies and prudent investment management by investing primarily in a portfolio of long-term municipal obligations,
the interest on which, in the opinion of bond counsel to the issuers, is exempt from federal income taxes. The Fund also seeks to provide shareholders with the
opportunity to own shares the value of which is exempt from Florida intangible personal property taxes. Effective September 16, 2008, BlackRock MuniYield
Florida Fund was renamed BlackRock MuniYield Investment Fund. No assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the 12 months ended July 31, 2009, the Fund returned 5.26% based on market price and 1.93% based on NAV. For the same period, the closed-end
Lipper General Municipal Debt Funds (Leveraged) category posted an average return of 2.20% based on market price and (2.40)% on a NAV basis. All returns
reflect reinvestment of dividends. The Fund’s discount to NAV, which narrowed during the period, accounts for the difference between performance based on
price and performance based on NAV. Sector allocation played an important role in determining how the Fund performed during the reporting period. The
Fund’s significant overweight in pre-refunded bonds in the one- to five-year maturity range aided comparative results, as the yield curve steepened.
Overweight exposure to the education and transportation sectors also enhanced the Fund’s performance.

Fund Summary as of July 31, 2009 BlackRock MuniYield New Jersey Fund, Inc.

Investment Objective

BlackRock MuniYield New Jersey Fund, Inc. (MYJ) (the “Fund”) seeks to provide shareholders with as high a level of current income exempt from federal
and New Jersey income taxes as is consistent with its investment policies and prudent investment management by investing primarily in a portfolio of long-
term, investment grade municipal obligations, the interest on which, in the opinion of bond counsel to the issuer, is exempt from federal income tax and New
Jersey personal income taxes. No assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the 12 months ended July 31, 2009, the Fund returned 5.96% based on market price and 4.50% based on NAV. For the same period, the closed-end
Lipper New Jersey Municipal Debt Funds category posted an average return of 4.58% based on market price and 1.31% on a NAV basis. All returns reflect
reinvestment of dividends. The Fund’s discount to NAV, which narrowed during the period, accounts for the difference between performance based on price
and performance based on NAV. Sector allocation played an important role in determining how the Fund performed during the reporting period. Enhancing the
performance of the Fund were its overweight positions in education, tax-backed and utility bonds. As the economic downturn continued, these essential serv-
ice sectors significantly outperformed all spread products.

The Benefits and Risks of Leveraging

The Funds may utilize leverage to seek to enhance the yield and NAV of
their Common Shares. However, these objectives cannot be achieved in all
interest rate environments.

To leverage, the Funds issue Preferred Shares, which pay dividends at pre-
vailing short-term interest rates, and invest the proceeds in long-term
municipal bonds. In general, the concept of leveraging is based on the
premise that the cost of assets to be obtained from leverage will be based
on short-term interest rates, which normally will be lower than the income
earned by each Fund on its longer-term portfolio investments. To the extent
that the total assets of the Fund (including the assets obtained from lever-
age) are invested in higher-yielding portfolio investments, the Fund’s
Common Shareholders will benefit from the incremental yield.

To illustrate these concepts, assume a Fund’s Common Shares capitalization
is $100 million and it issues Preferred Shares 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 3% and long-
term interest rates are 6%, the yield curve has a strongly positive slope. In
this case, the Fund pays dividends on the $50 million of Preferred Shares
based on the lower short-term interest rates. At the same time, the securi-
ties purchased by the Fund with assets received from the Preferred Shares
issuance earn the income based on long-term interest rates. In this case,
the dividends paid to Preferred Shareholders are significantly lower than
the income earned on the Fund’s long-term investments, and therefore the
Common Shareholders are the beneficiaries of the incremental net income.

Conversely, if prevailing short-term interest rates rise above long-term inter-
est rates of 6%, the yield curve has a negative slope. In this case, the Fund
pays dividends on the higher short-term interest rates whereas the Fund’s
total portfolio earns income based on lower long-term interest rates. If
short-term interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental net income pickup on the
Common Shares will be reduced or eliminated completely.

Furthermore, the value of the Fund’s portfolio investments generally varies
inversely with the direction of long-term interest rates, although other factors
can influence the value of portfolio investments. In contrast, the redemp-
tion value of the Fund’s Preferred Shares does not fluctuate in relation to
interest rates. As a result, changes in interest rates can influence the Fund’s
NAV positively or negatively in addition to the impact on Fund performance
from leverage from Preferred Shares discussed above.

The Funds may also, from time to time, leverage their assets through the
use of tender option bond (“TOB”) programs, as described in Note 1 of the
Notes to Financial Statements. TOB investments generally will provide the

Funds with economic benefits in periods of declining short-term interest
rates, but expose the Funds to risks during periods of rising short-term
interest rates similar to those associated with Preferred Shares issued by
the Funds, as described above. Additionally, fluctuations in the market value
of municipal bonds deposited into the TOB trust may adversely affect the
Funds’ NAV per share.

The use of leverage may enhance opportunities for increased returns to the
Funds and Common Shareholders, but as described above, it also creates
risks as short- or long-term interest rates fluctuate. Leverage also will gen-
erally cause greater changes in the Funds’ NAV, market price and dividend
rate than a comparable portfolio without leverage. If the income derived
from securities purchased with assets received from leverage exceeds the
cost of leverage, the Funds’ net income will be greater than if leverage had
not been used. Conversely, if the income from the securities purchased is
not sufficient to cover the cost of leverage, the Funds’ net income will be
less than if leverage had not been used, and therefore the amount avail-
able for distribution to Common Shareholders will be reduced. The Funds
may be required to sell portfolio securities at inopportune times or at dis-
tressed values in order to comply with regulatory requirements applicable
to the use of leverage or as required by the terms of leverage instruments,
which may cause the Funds to incur losses. The use of leverage may limit
the Funds’ ability to invest in certain types of securities or use certain types
of hedging strategies, such as in the case of certain restrictions imposed
by ratings agencies that rate preferred shares issued by a Fund. The Funds
will incur expenses in connection with the use of leverage, all of which are
borne by the holders of the Common Shares and may reduce returns on
the Common Shares.

Under the Investment Company Act of 1940, each Fund is permitted to
issue Preferred Shares in an amount of up to 50% of its total managed
assets at the time of issuance. Under normal circumstances, each Fund
anticipates that the total economic leverage from Preferred Shares and
TOBs will not exceed 50% of its total managed assets at the time such
leverage is incurred. As of July 31, 2009, the Funds had economic leverage
from Preferred Shares and TOBs as a percentage of their total managed
assets as follows:

  Percent of 
  Leverage 
BlackRock Muni New York Intermediate Duration Fund, Inc  36% 
BlackRock MuniYield Arizona Fund, Inc  42% 
BlackRock MuniYield California Fund, Inc  39% 
BlackRock MuniYield Investment Fund  39% 
BlackRock MuniYield New Jersey Fund, Inc  35% 

Derivative Financial Instruments

The Funds may invest in various derivative instruments, including financial
futures contracts, as specified in Note 2 of the Notes to Financial
Statements, which constitute forms of economic leverage. Such instruments
are used to obtain exposure to a market without owning or taking physical
custody of securities or to hedge market and/or interest rate risks. Such
derivative instruments involve risks, including the imperfect correlation
between the value of a derivative instrument and the underlying asset, pos-
sible default of the counterparty to the transaction and illiquidity of the
derivative instrument. The Funds’ ability to successfully use a derivative

instrument depends on the investment advisor’s ability to accurately pre-
dict pertinent market movements, which cannot be assured. The use of
derivative instruments may result in losses greater than if they had not
been used, may require a Fund to sell or purchase portfolio securities at
inopportune times or for distressed values, may limit the amount of appre-
ciation a Fund can realize on an investment or may cause a Fund to hold a
security that it might otherwise sell. The Funds’ investments in these instru-
ments are discussed in detail in the Notes to Financial Statements.

•  Effective August 1, 2008, the Fund adopted Financial Accounting Standards Board 
  Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” 
  (“FAS 157”). FAS 157 clarifies the definition of fair value, establishes a framework for 
  measuring fair values and requires additional disclosures about the use of fair value 
  measurements. Various inputs are used in determining the fair value of investments, 
  which are as follows:     
  •  Level 1 — price quotations in active markets/exchanges for identical securities 
  •  Level 2 — other observable inputs (including, but not limited to: quoted prices for 
    similar assets or liabilities in markets that are active, quoted prices for identical 
    or similar assets or liabilities in markets that are not active, inputs other than 
    quoted prices that are observable for the assets or liabilities (such as interest 
    rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and 
    default rates) or other market-corroborated inputs)   
  •  Level 3 — unobservable inputs based on the best information available in the 
    circumstances, to the extent observable inputs are not available (including the 
    Fund’s own assumptions used in determining the fair value of investments) 
  The inputs or methodology used for valuing securities are not necessarily an indica- 
  tion of the risk associated with investing in those securities. For information about 
  the Fund’s policy regarding valuation of investments and other significant accounting 
  policies, please refer to Note 1 of the Notes to Financial Statements. 
  The following table summarizes the inputs used as of July 31, 2009 in determining 
  the fair valuation of the Fund’s investments:     
  Valuation    Investments in 
  Inputs    Securities 
        Assets 
  Level 1 — Short-Term Securities    $ 7,607,697

•  Effective August 1, 2008, the Fund adopted Financial Accounting Standards Board 
  Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” 
  (“FAS 157”). FAS 157 clarifies the definition of fair value, establishes a framework for 
  measuring fair values and requires additional disclosures about the use of fair value 
  measurements. Various inputs are used in determining the fair value of investments, 
  which are as follows:     
  •  Level 1 — price quotations in active markets/exchanges for identical securities 
  •  Level 2 — other observable inputs (including, but not limited to: quoted prices for 
    similar assets or liabilities in markets that are active, quoted prices for identical 
    or similar assets or liabilities in markets that are not active, inputs other than 
    quoted prices that are observable for the assets or liabilities (such as interest 
    rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and 
    default rates) or other market-corroborated inputs)     
  •  Level 3 — unobservable inputs based on the best information available in the 
    circumstances, to the extent observable inputs are not available (including the 
    Fund’s own assumptions used in determining the fair value of investments) 
  The inputs or methodology used for valuing securities are not necessarily an indica- 
  tion of the risk associated with investing in those securities. For information about 
  the Fund’s policy regarding valuation of investments and other significant accounting 
  policies, please refer to Note 1 of the Notes to Financial Statements. 
  The following table summarizes the inputs used as of July 31, 2009 in determining 
  the fair valuation of the Fund’s investments:

•  Financial Accounting Standards Board Statement of Financial Accounting Standards 
  No. 157, “Fair Value Measurements” clarifies the definition of fair value, establishes a 
  framework for measuring fair values and requires additional disclosures about the 
  use of fair value measurements. Various inputs are used in determining the fair value 
  of investments, which are as follows:   
  •  Level 1 — price quotations in active markets/exchanges for identical securities 
  •  Level 2 — other observable inputs (including, but not limited to: quoted prices for 
    similar assets or liabilities in markets that are active, quoted prices for identical 
    or similar assets or liabilities in markets that are not active, inputs other than 
    quoted prices that are observable for the assets or liabilities (such as interest 
    rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and 
    default rates) or other market-corroborated inputs)   
  •  Level 3 — unobservable inputs based on the best information available in the 
    circumstances, to the extent observable inputs are not available (including the 
    Fund’s own assumptions used in determining the fair value of investments) 
  The inputs or methodology used for valuing securities are not necessarily an indica- 
  tion of the risk associated with investing in those securities. For information about 
  the Fund’s policy regarding valuation of investments and other significant accounting 
  policies, please refer to Note 1 of the Notes to Financial Statements. 
  The following table summarizes the inputs used as of July 31, 2009 in determining 
  the fair valuation of the Fund’s investments:   
  Valuation  Investments in

Notes to Financial Statements

1. Organization and Significant Accounting Policies:

BlackRock Muni New York Intermediate Duration Fund, Inc. (“Muni New
York”), BlackRock MuniYield Arizona Fund, Inc. (“MuniYield Arizona”),
BlackRock MuniYield California Fund, Inc. (“MuniYield California”),
BlackRock MuniYield Investment Fund (formerly BlackRock MuniYield
Florida Fund) (“MuniYield Investment”) and BlackRock MuniYield New
Jersey Fund, Inc. (“MuniYield New Jersey”) (collectively, the “Funds” or
individually as the “Fund”), are registered under the Investment Company
Act of 1940, as amended (the “1940 Act”), as non-diversified, closed-end
management investment companies. Muni New York, MuniYield Arizona,
MuniYield California, and MuniYield New Jersey are organized as Maryland
corporations. MuniYield Investment is organized as a Massachusetts busi-
ness trust. The Funds’ financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America,
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 values of their Common Shares on a
daily basis.

The following is a summary of significant accounting policies followed by
the Funds:

Valuation of Investments: Municipal investments (including commitments
to purchase such investments on a “when-issued” basis) are valued on the
basis of prices provided by dealers or pricing services selected under the
supervision of each Fund’s Board of Directors/Trustees (the “Board”). In
determining the value of a particular investment, pricing services may use
certain information with respect to transactions in such investments, quota-
tions from dealers, pricing matrixes, market transactions in comparable
investments and information with respect to various relationships between
investments. Financial futures contracts traded on exchanges are valued at
their last sale price. Short-term securities with maturities less than 60 days
may be valued at amortized cost, which approximates fair value. Invest-
ments in open-end investment companies are valued at net asset value
each business day.

In the event that application of these methods of valuation results in a
price for an investment which is deemed not to be representative of the
market value of such investment, the investment will be valued by a
method approved by each Fund’s Board as reflecting fair value (“Fair Value
Assets”). When determining the price for Fair Value Assets, the investment
advisor and/or the sub-advisor seeks to determine the price that each
Fund might reasonably expect to receive from the current sale of that asset
in an arm’s length transaction. Fair value determinations shall be based
upon all available factors that the investment advisor and/or sub-advisor
deems relevant. The pricing of all Fair Value Assets is subsequently reported
to the Board or a committee thereof.

Forward Commitments and When-Issued Delayed Delivery Securities: The
Funds may purchase securities on a when-issued basis and may purchase
or sell securities on a forward commitment basis. Settlement of such trans-
actions normally occurs within a month or more after the purchase or sale
commitment is made. The Funds may purchase securities under such

conditions only with the intention of actually acquiring them, but may enter
into a separate agreement to sell the securities before the settlement date.
Since the value of securities purchased may fluctuate prior to settlement,
the Funds may be required to pay more at settlement than the security
is worth. In addition, the purchaser is not entitled to any of the interest
earned prior to settlement. When purchasing a security on a delayed-
delivery basis the Funds assume the rights and risks of ownership of the
security, including the risk of price and yield fluctuations. In the event of
default by the counterparty, the Funds’ maximum amount of loss is the
unrealized gain of the commitment.

Municipal Bonds Transferred to Tender Option Bond Trusts: The Funds
leverage their assets through the use of tender option bond trusts (“TOBs”).
A TOB is established by a third party sponsor forming a special purpose
entity, into which one or more funds, or an agent on behalf of the funds,
transfers municipal bonds. Other funds managed by the investment advisor
may also contribute municipal bonds to a TOB into which a Fund has con-
tributed bonds. A TOB typically issues two classes of beneficial interests:
short-term floating rate certificates, which are sold to third party investors,
and residual certificates (“TOB Residuals”), which are generally issued to
the participating funds that made the transfer. The TOB Residuals held by a
Fund include the right of the Fund (1) to cause the holders of a propor-
tional share of the floating rate certificates to tender their certificates at
par, and (2) to transfer, within seven days, a corresponding share of the
municipal bonds from the TOB to the Fund. The TOB may also be termi-
nated without the consent of the Fund upon the occurrence of certain
events as defined in the TOB agreements. Such termination events may
include the bankruptcy or default of the municipal bond, a substantial
downgrade in credit quality of the municipal bond, the inability of the TOB
to obtain quarterly or annual renewal of the liquidity support agreement, a
substantial decline in market value of the municipal bond or the inability to
remarket the short-term floating rate certificates to third party investors.

The cash received by the TOB from the sale of the short-term floating rate
certificates, less transaction expenses, is paid to the Fund, which typically
invests the cash in additional municipal bonds. Each Fund’s transfer of the
municipal bonds to a TOB is accounted for as a secured borrowing, there-
fore the municipal bonds deposited into a TOB are presented in the Funds’
Schedules of Investments and the proceeds from the issuance of the short-
term floating rate certificates are shown as trust certificates in the
Statements of Assets and Liabilities.

Interest income from the underlying securities 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 the Funds. 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. At July 31, 2009, the aggregate value of the
underlying municipal bonds transferred to TOBs, the related liability for
trust certificates and the range of interest rates on the liability for the
trust certificates were as follows:

      0.41% – 
MuniYield New Jersey  $ 10,149,784       $ 6,603,701  1.56% 
For the year ended July 31, 2009, the Funds’ average trust certificates out- 
standing and the daily weighted average interest rate were as follows: 
    Average Trust  Daily Weighted 
    Certificates  Average 
    Outstanding  Interest Rate 
Muni New York    $ 1,292,013  1.62% 
MuniYield Arizona    $ 1,253,379  2.38% 
MuniYield California    $ 65,362,281  1.63% 
MuniYield Investment    $ 23,631,071  1.57% 
MuniYield New Jersey    $ 9,097,710  1.92% 

Financial transactions executed through TOBs generally will underperform
the market for fixed rate municipal bonds when short-term interest rates
rise, but tend to outperform the market for fixed rate bonds when interest
rates decline or remain relatively stable. Should short-term interest rates
rise, the Funds’ investments in TOBs may adversely affect the Funds’ invest-
ment income and distributions to shareholders. Also, fluctuations in the
market value of municipal bonds deposited into the TOB may adversely
affect the Funds’ net asset value per share.

Zero-Coupon Bonds: Each Fund may invest in zero-coupon bonds, which
are normally issued at a significant discount from face value and do not
provide for periodic interest payments. Zero-coupon bonds may experience
greater volatility in market value than similar maturity debt obligations
which provide for regular interest payments.

Segregation and Collateralization: In cases in which the 1940 Act and
the interpretive positions of the Securities and Exchange Commission
(“SEC”) require that each Fund either receive collateral or segregate
assets in connection with certain investments (e.g., financial futures con-
tracts) each Fund will, consistent with SEC rules and/or certain interpretive
letters issued by the SEC, segregate collateral or designate on its books
and records cash or other liquid securities having a market value at least
equal to the amount that would otherwise be required to be physically seg-
regated. Furthermore, based on requirements and agreements with certain
exchanges and third party broker-dealers, each party has requirements to
deliver/deposit securities as collateral for certain investments (e.g., finan-
cial futures contracts). As part of these agreements, when the value of these
investments achieves a previously agreed upon value (minimum transfer
amount), each party may be required to deliver additional collateral.

Investment Transactions and Investment Income: For financial reporting
purposes, investment transactions are recorded on the dates the trans-
actions 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 method. Each Fund amortizes all premiums and discounts
on debt securities.

Dividends and Distributions: Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates. Dividends and distributions to Preferred Shareholders
are accrued and determined as described in Note 7.

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.

Each Fund files US federal and various state and local tax returns. No
income tax returns are currently under examination. The statute of limita-
tions on the Funds’ US federal tax returns remains open for the four peri-
ods ended as follows:

  Year Ended  Period  Year Ended  Year Ended

The statutes of limitations on the Funds’ state and local tax returns may
remain open for an additional year depending upon the jurisdiction.

Recent Accounting Pronouncement: In June 2009, Statement of Financial
Accounting Standards No. 166, “Accounting for Transfers of Financial Assets
— an amendment of FASB Statement No. 140” (“FAS 166”), was issued.
FAS 166 is intended to improve the relevance, representational faithfulness
and comparability of the information that a reporting entity provides in its
financial statements about a transfer of financial assets; the effects of a
transfer on its financial position, financial performance, and cash flows;
and a transferor’s continuing involvement, if any, in transferred financial
assets. FAS 166 is effective for financial statements issued for fiscal years
and interim periods beginning after November 15, 2009. Earlier application
is prohibited. The recognition and measurement provisions of FAS 166 must
be applied to transfers occurring on or after the effective date. Additionally,
the disclosure provisions of FAS 166 should be applied to transfers that
occurred both before and after the effective date of FAS 166. The impact of
FAS 166 on the Funds’ financial statement disclosures, if any, is currently
being assessed.

Deferred Compensation and BlackRock Closed-End Share Equivalent
Investment Plan: Under the deferred compensation plan approved by each

ANNUAL REPORT JULY 31, 2009 39

Notes to Financial Statements (continued)

Fund’s Board, non-interested Directors (“Independent Directors”) may defer
a portion of their annual complex-wide compensation. Deferred amounts
earn an approximate return as though equivalent dollar amounts had been
invested in common shares of other certain BlackRock Closed-End Funds
selected by the Independent Directors. This has approximately the same
economic effect for the Independent Directors as if the Independent
Directors had invested the deferred amounts directly in other certain
BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations thereunder
represent general unsecured claims against the general assets of each
Fund. Each Fund may, however, elect to invest in common shares of other
certain BlackRock Closed-End Funds selected by the Independent Directors
in order to match their deferred compensation obligations.

Other: Expenses directly related to a Fund are charged to that Fund. Other
operating expenses shared by several funds are prorated among those
funds on the basis of relative net assets or other appropriate methods.

2. Derivative Financial Instruments:

The Funds may engage in various portfolio investment strategies both to
increase the return of the Funds and to economically hedge, or protect,
their exposure to interest rate movements and movements in the securities
markets. Losses may arise if the value of the contract decreases due to an
unfavorable change in the price of the underlying security or if the counter-
party does not perform under the contract. To the extent amounts due to
the Funds from their counterparties are not fully collateralized contractually
or otherwise, the Funds bear the risk of loss from counterparty non-per-
formance. See Note 1 “Segregation and Collateralization” for information
with respect to collateral practices.

The Funds are subject to interest rate risk in the normal course of pursuing
their investment objectives by investing in various derivative financial instru-
ments, as described below.

Financial Futures Contracts: The Funds may purchase or sell financial
futures contracts and options on financial futures contracts to gain expo-
sure to, or economically hedge against, changes in interest rates (interest
rate risk). Financial futures contracts are contracts for delayed delivery of
securities at a specific future date and at a specific price or yield. Pursuant
to the contract, the Funds agree 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 margin variation and are recognized by
the Funds as unrealized gains or losses. When the contract is closed, the
Funds record 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. The use of financial futures transactions involves the risk of
an imperfect correlation in the movements in the price of futures contracts,
interest rates and the underlying assets. Financial futures transactions
involve minimal counterparty risk since financial futures contracts are
guaranteed against default by the exchange on which they trade.
Counterparty risk is also minimized by the daily margin variation.

3. Investment Advisory Agreement and Other Transactions
with Affiliates:

The PNC Financial Services Group, Inc. (“PNC”) and Bank of America
Corporation (“BAC”) are the largest stockholders of BlackRock, Inc.
(“BlackRock”). BAC became a stockholder of BlackRock following its
acquisition of Merrill Lynch & Co. (“Merrill Lynch”) on January 1, 2009.
Prior to that date, both PNC and Merrill Lynch were considered affiliates
of the Funds under the 1940 Act. Subsequent to the acquisition, PNC
remains an affiliate, but due to the restructuring of Merrill Lynch’s owner-
ship interest of BlackRock, BAC is not deemed to be an affiliate under
the 1940 Act.

Each Fund entered into an Investment Advisory Agreement with BlackRock
Advisors, LLC (the “Manager”), the Funds’ investment advisor, an indirect,
wholly owned subsidiary of BlackRock, to provide investment advisory and
administration services.

The Manager is responsible for the management of each Fund’s portfolio
and provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of each Fund. For such services,
Muni New York pays the Manager a monthly fee at an annual rate of
0.55%, and MuniYield Arizona, MuniYield California, MuniYield Investment
and MuniYield New Jersey pay 0.50% of each Fund’s average daily net
assets. Average daily net assets is the average daily value of each Fund’s
total assets minus the sum of its accrued liabilities.

The Manager has contractually agreed to waive a portion of its fee during
the first seven years of Muni New York’s operations ending July 2010
as follows:

  Fee Waiver 
  (As a Percentage 
  of Average Daily 
  Net Assets) 
Year 6 through July 31, 2009  0.10% 
Year 7 through July 31, 2010  0.05% 
The Manager has not agreed to waive any portion of its fee beyond 
July 31, 2010.

Notes to Financial Statements (continued) 
Such waivers are included in fees waived by advisor on the Statements 
of Operations:     
  Fees Waived 
  by Manager 
Muni New York  $ 83,359 
The Manager has agreed to waive its advisory fees by the amount of invest- 
ment advisory fees each Fund pays to the Manager indirectly through its 
investment in affiliated money market funds, which are included in fees 
waived by advisor in the Statements of Operations. For the year ended July 
31, 2009, the amounts waived were as follows:     
    Amount 
Muni New York  $ 14,241 
MuniYield Arizona  $ 20,372 
MuniYield California  $ 49,215 
MuniYield Investment  $ 33,111 
MuniYield New Jersey  $ 20,530 
The Manager has entered into separate sub-advisory agreements with 
BlackRock Investment Management, LLC (“BIM”), an affiliate of the   
Manager, with respect to each Fund, under which the Manager pays BIM 
for services it provides, a monthly fee that is a percentage of the invest- 
ment advisory fee paid by each Fund to the Manager.     

For the year ended July 31, 2009, the Funds reimbursed the Manager for 
certain accounting services in the following amounts, which are included in 
accounting services in the Statements of Operations:   
    Amount 
Muni New York    $ 1,657 
MuniYield Arizona    $ 1,883 
MuniYield California    $ 8,525 
MuniYield Investment    $ 5,356 
MuniYield New Jersey    $ 6,066 
Certain officers and/or directors of the Funds are officers and/or directors 
of BlackRock or its affiliates. The Funds reimburse the Manager for com- 
pensation paid to the Funds’ Chief Compliance Officer.   
4. Investments:     
Purchases and sales of investments, excluding short-term securities, for the 
year ended July 31, 2009 were as follows:     
  Purchases  Sales 
Muni New York  $ 25,784,627  $ 25,005,749 
MuniYield Arizona  $ 35,169,070  $ 40,066,728 
MuniYield California  $168,879,112  $182,666,168 
MuniYield Investment  $171,012,287  $179,675,387 
MuniYield New Jersey  $ 63,376,074  $ 73,947,752 

5. Income Tax Information:           
Reclassifications: Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to 
reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. The 
following permanent differences as of July 31, 2009 attributable to amortization methods on fixed income securities, the tax classification of distributions 
received from a regulated investment company, the reclassification of distributions, the book to tax difference on the sale of residual interests in tender 
option bond trusts and the expiration of capital loss carryforwards were reclassified to the following accounts:     
  Muni  MuniYield  MuniYield  MuniYield  MuniYield

6. Concentration, Market and Credit Risk:

Each Fund invests a substantial amount of its assets in issuers located in a
single state or limited number of states. Please see the Schedules of
Investments for concentrations in specific states.

Many municipalities insure repayment of their bonds, which reduces
the risk of loss due to issuer default. The market value of these bonds
may fluctuate for other reasons, including market perception of the value
of such insurance, and there is no guarantee that the insurer will meet
its obligation.

In the normal course of business, the Funds invest in securities and enter
into transactions where risks exist due to fluctuations in the market (market
risk) or failure of the issuer of a security to meet all its obligations (credit
risk). The value of securities held by the Funds may decline in response to
certain events, including those directly involving the issuers whose securi-
ties are owned by the Funds; conditions affecting the general economy;
overall market changes; local, regional or global political, social or eco-
nomic instability; and currency and interest rate and price fluctuations.
Similar to credit risk, the Funds may be exposed to counterparty risk, or the
risk that an entity with which the Funds have unsettled or open transac-
tions may default. Financial assets, which potentially expose the Funds to
credit and counterparty risks, consist principally of investments and cash

due from counterparties. The extent of the Funds’ exposure to credit and
counterparty risks with respect to these financial assets is approximated by
their value recorded in the Funds’ Statements of Assets and Liabilities.

7. Capital Share Transactions:

Each Fund is authorized to issue 200 million shares (MuniYield Investment
is authorized to issue an unlimited amount of shares par value $0.10 per
share) including Preferred Shares, all of which were initially classified as
Common Shares. Each Board is authorized, however, to reclassify any
unissued shares of Common Shares without approval of Common
Shareholders.

Common Shares

Shares issued and outstanding for MuniYield Arizona for the year ended
July 31, 2009, the period November 1, 2007 to July 31, 2008 and the
year ended October 31, 2007 increased by 7,393, 14,368 and 13,972,
respectively, as a result of dividend reinvestment.

Shares issued and outstanding remained constant for Muni New York for the
year ended July 31, 2009, the period ended July 31, 2008 and the year
ended May 31, 2008, for MuniYield California for the year ended July 31,
2009, the period ended July 31, 2008 and the year ended October 31,
2007, for MuniYield Investment for the period ended January 31, 2009,

Notes to Financial Statements (continued)

the period ended July 31, 2008 and the year ended October 31, 2007 and
for MuniYield New Jersey for the year ended July 31, 2009, the period
ended July 31, 2008 and the year ended November 30, 2007.

Preferred Shares

The Preferred Shares are redeemable at the option of each Fund, in whole
or in part, on any dividend payment date at its liquidation preference per
share plus any accumulated or unpaid dividends whether or not declared.
The Preferred Shares are also subject to mandatory redemption at their
liquidation preference plus any accumulated or unpaid dividends, whether
or not declared, if certain requirements relating to the composition of
the assets and liabilities of the Funds, as set forth in each Fund’s Articles
Supplementary or Certificate of Designation as applicable, (“Governing
Instrument”), are not satisfied.

From time to time in the future, the Funds may affect repurchases of
Preferred Shares at prices below their liquidation preferences as agreed
upon by the Funds and seller. The Funds also may redeem such shares
from time to time as provided in the applicable Governing Instrument. The
Funds intend to affect such redemptions and/or repurchases to the extent
necessary to maintain applicable asset coverage requirements or for such
other reasons as the Board may determine.

The holders of Preferred Shares have voting rights equal to the holders of
Common Shares (one vote per share) and will vote together with the hold-
ers of Common Shares (one vote per share) as a single class. However,
holders of Preferred Shares, voting as a separate class, are also entitled to
elect two directors for each Fund. In addition, the 1940 Act requires that
along with approval by shareholders that might otherwise be required, the
approval of the holders of a majority of any outstanding Preferred Shares,
voting separately as a class, would be required to (a) adopt any plan of
reorganization that would adversely affect the Preferred Shares (b) change
the Fund’s sub classification as a closed-end investment company or
change its fundamental investment restrictions or (c) change its business
so as to cease to be an investment company.

The Funds had the following series of Preferred Shares outstanding, effec- 
tive yields and reset frequency as of July 31, 2009:     
        Reset 
    Preferred  Effective Frequency 
  Series  Shares  Yield  Days 
Muni New York  F7  1,185  1.57%2  7 
MuniYield Arizona  A  499  0.58%1  7 
  B  668  0.52%1  7 
  C  385  1.57%2  7 
MuniYield California  A  1,453  0.38%1  28 
  B  1,453  0.58%1  7 
  C  484  0.58%1  28

MuniYield New Jersey  A  2,061  0.58%1  7 
  B  1,288  0.58%1  7 
  C  739  1.57%2  7 
   1 The maximum applicable rate on this series of Preferred Shares is the higher 
       of 110% of the AA commercial paper rate or 110% of 90% of the Kenny S&P 
       30-day High Grade Index rate divided by 1.00 minus the marginal tax rate.   

2 The maximum applicable rate on this series of Preferred Shares is the higher
of 110% plus or times (i) the Telerate/BAA LIBOR or (ii) 90% of the Kenny S&P
30-day High Grade Index rate divided by 1.00 minus the marginal tax rate.

Dividends on 7- or 28-day Preferred Shares are cumulative at a rate, which
is reset every 7 or 28 days, respectively, based on the results of an auc-
tion. If the Preferred Shares fail to clear the auction on an auction date, the
Fund is required to pay the maximum applicable rate on the Preferred
Shares to holders of such shares for successive dividend periods until such
time as the shares are successfully auctioned. The maximum applicable
rate on the Preferred Shares is footnoted as applicable on the above chart.
The low, high and average dividend rates on the Preferred Shares for each
Fund for the year ended July 31, 2009 were as follows:

  Series  Low  High  Average 
Muni New York  F7  1.42%  11.76%  2.98% 
MuniYield Arizona  A  0.38%  12.57%  1.91% 
  B  0.43%  10.21%  1.90% 
  C  1.42%  11.76%  2.82% 
MuniYield California   A  0.38%  8.65%  1.92% 
  B  0.38%  12.57%  1.85% 
  C  0.43%  12.57%  2.06% 
  D  1.49%  10.38%  2.79% 
MuniYield Investment  A  0.38%  12.57%  1.91% 
  B  0.35%  12.26%  1.88% 
  C  1.46%  11.42%  2.80% 
MuniYield New Jersey  A  0.38%  12.57%  1.85% 
  B  0.40%  11.35%  1.84% 
  C  1.49%  10.38%  2.79% 

Since February 13, 2008, the Preferred Shares of each Fund failed to
clear any of their auctions. As a result, the Preferred Shares dividend rates
were reset to the maximum applicable rate, which ranged from 0.35% to
12.57% for the year ended July 31, 2009. A failed auction is not an event
of default for the Funds, but it has a negative impact on the liquidity of
Preferred Shares. A failed auction occurs when there are more sellers of a
Fund’s auction rate preferred shares than buyers. It is impossible to predict
how long this imbalance will last. A successful auction for each Fund’s
Preferred Shares may not occur for some time, if ever, and even if liquidity
does resume, Preferred Shareholders may not have the ability to sell the
Preferred Shares at their liquidation preference.

The Funds may not declare dividends or make other distributions on
Common Shares or purchase any such shares if, at the time of the
declaration, distribution or purchase, asset coverage with respect to the
outstanding Preferred Shares is less than 200%.

Prior to December 22, 2008, the Funds paid commissions to certain
broker-dealers at the end of each auction at an annual rate of 0.25%, cal-
culated on the aggregated principal amount. As of December 22, 2008,
commissions paid to broker-dealers on Preferred Shares that experienced
a failed auction were reduced to 0.15% on the aggregate principal
amount. The Funds will pay commissions of 0.25% on the aggregate princi-
pal amount of all shares that successfully clear their auctions. Merrill
Lynch, Pierce, Fenner & Smith Incorporated, a wholly owned subsidiary of
Merrill Lynch, earned commissions for the period August 1, 2008 to

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of BlackRock MuniYield
Investment Fund and to the Shareholders and Board of Directors of
BlackRock Muni New York Intermediate Duration Fund, Inc., BlackRock
MuniYield Arizona Fund, Inc., BlackRock MuniYield California Fund, Inc.,
and BlackRock MuniYield New Jersey Fund, Inc. (collectively, the “Funds”):

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of BlackRock Muni New York
Intermediate Duration Fund, Inc. as of July 31, 2009, and the related
statement of operations for the year then ended, the statements of
changes in net assets for the year then ended, the period June 1, 2008 to
July 31, 2008 and for the year ended May 31, 2008, and the financial
highlights for the year then ended, the period June 1, 2008 to July 31,
2008 and for each of the two years in the period ended May 31, 2008.
We have also audited the accompanying statements of assets and liabili-
ties, including the schedules of investments, of BlackRock MuniYield
Arizona Fund, Inc. and BlackRock MuniYield Investment Fund (formerly
BlackRock MuniYield Florida Fund) as of July 31, 2009, and the related
statements of operations for the year then ended, the statements of
changes in net assets for the year then ended, the period November 1,
2007 to July 31, 2008 and for the year ended October 31, 2007, and the
financial highlights for each of the respective periods presented. We have
also audited the accompanying statement of assets and liabilities, includ-
ing the schedule of investments, of BlackRock MuniYield California Fund,
Inc. as of July 31, 2009, and the related statements of operations and
cash flows for the year then ended, the statements of changes in net
assets for the year then ended, the period November 1, 2007 to July 31,
2008 and for the year ended October 31, 2007, and the financial high-
lights for each of the respective periods presented. We have also audited
the accompanying statement of assets and liabilities, including the sched-
ule of investments, of BlackRock MuniYield New Jersey Fund, Inc. as of
July 31, 2009, and the related statement of operations for the year then
ended, the statements of changes in net assets for the year then ended,
the period December 1, 2007 to July 31, 2008 and for the year ended
November 30, 2007, and the financial highlights for each of the respec-
tive periods presented. These financial statements and financial highlights
are the responsibility of the Funds’ management. Our responsibility is to
express an opinion on these financial statements and financial highlights
based on our audits. The financial highlights for each of the two years in
the period ended May 31, 2006 for BlackRock Muni New York
Intermediate Duration Fund, Inc. were audited by other auditors whose
report, dated July 14, 2006, expressed an unqualified opinion on those
financial highlights.

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 assur-
ance 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, an audit of their internal control over finan-
cial 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 disclo-
sures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluat-
ing the overall financial statement presentation. Our procedures included
confirmation of securities owned as of July 31, 2009, by correspondence
with the custodian and brokers; where replies were not received from bro-
kers, we performed other auditing procedures.We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
BlackRock Muni New York Intermediate Duration Fund, Inc. as of July 31,
2009, the results of its operations for the year then ended, the changes
in its net assets for the year then ended, the period June 1, 2008 to
July 31, 2008 and for the year ended May 31, 2008, and the financial
highlights for the year then ended, the period June 1, 2008 to July 31,
2008 and for each of the two years in the period ended May 31, 2008,
in conformity with accounting principles generally accepted in the United
States of America. Additionally, in our opinion, the financial statements
and financial highlights referred to above present fairly, in all material
respects, the financial position of BlackRock MuniYield Arizona Fund, Inc.
and of BlackRock MuniYield Investment Fund as of July 31, 2009, the
results of their operations for the year then ended, the changes in their
net assets for the year then ended, the period November 1, 2007 to
July 31, 2008 and for the year ended October 31, 2007, and the financial
highlights for each of the respective periods presented, in conformity with
accounting principles generally accepted in the United States of America.
Additionally, in our opinion, the financial statements and financial high-
lights referred to above present fairly, in all material respects, the financial
position of BlackRock MuniYield California Fund, Inc. as of July 31, 2009,
the results of its operations and its cash flows for the year then ended,
the changes in its net assets for the year then ended, the period
November 1, 2007 to July 31, 2008 and for the year ended October 31,
2007, and the financial highlights for each of the respective periods

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements

The Board of Directors (each, a “Board” and, collectively, the “Boards,”
the members of which are referred to as “Board Members”) of each of
BlackRock Muni New York Intermediate Duration Fund, Inc. (“MNE”),
BlackRock MuniYield Arizona Fund, Inc. (“MZA”), BlackRock MuniYield
California Fund, Inc. (“MYC”), BlackRock MuniYield Investment Fund
(“MYF”) and BlackRock MuniYield New Jersey Fund, Inc. (“MYJ” and,
together with MNE, MZA, MYC and MYF, each a “Fund” and, collectively,
the “Funds”) met on April 14, 2009 and May 28 – 29, 2009 to consider
the approval of its respective Fund’s investment advisory agreement (each,
an “Advisory Agreement”) with BlackRock Advisors, LLC (the “Manager”),
the Fund’s investment advisor. Each Board also considered the approval of
the sub-advisory agreement (each, a “Sub-Advisory Agreement”) between
its respective Fund, the Manager and BlackRock Investment Management,
LLC (the “Sub-Advisor”). The Manager and the Sub-Advisor are referred to
herein as “BlackRock.” The Advisory Agreements and the Sub-Advisory
Agreements are referred to herein as the “Agreements.” Unless otherwise
indicated, references to actions taken by the “Board” or the “Boards” shall
mean each Board acting independently with respect to its respective Fund.

Activities and Composition of the Boards

Each Board consists of twelve individuals, ten of whom are not “interested
persons” as defined in the Investment Company Act of 1940, as amended
(the “1940 Act”) (the “Independent Board Members”). The Board Members
of each Fund are responsible for the oversight of the operations of such
Fund and perform the various duties imposed on the directors of invest-
ment companies by the 1940 Act. The Independent Board Members have
retained independent legal counsel to assist them in connection with their
duties. The Chairman of each Board is an Independent Board Member.
Each Board has established five standing committees: an Audit Committee,
a Governance and Nominating Committee, a Compliance Committee, a
Performance Oversight Committee and an Executive Committee, each of
which is composed of Independent Board Members (except for the
Executive Committee, which has one interested Board Member) and is
chaired by an Independent Board Member. In addition, each Board has
established an Ad Hoc Committee on Auction Market Preferred Shares.

The Agreements

Pursuant to the 1940 Act, each Board is required to consider the continua-
tion of the Agreements on an annual basis. In connection with this process,
each Board assessed, among other things, the nature, scope and quality of
the services provided to its respective Fund by the personnel of BlackRock
and its affiliates, including investment management, administrative serv-
ices, shareholder services, oversight of fund accounting and custody,
marketing services and assistance in meeting legal and regulatory
requirements.

Throughout the year, the Boards, acting directly and through their commit-
tees, considers at each of their meetings factors that are relevant to their
annual consideration of the renewal of the Agreements, including the
services and support provided by BlackRock to the Funds and their share-
holders. Among the matters the Boards considered were: (a) investment
performance for one-, three- and five-year periods, as applicable, against

peer funds, and applicable benchmarks, if any, as well as senior manage-
ment and portfolio managers’ analysis of the reasons for any underperfor-
mance against its peers; (b) fees, including advisory and other amounts
paid to BlackRock and its affiliates by the Funds for services such as call
center and fund accounting; (c) the Funds’ operating expenses; (d) the
resources devoted to, and compliance reports relating to, the Funds’ invest-
ment objectives, policies and restrictions; (e) the Funds’ compliance with
their Code of Ethics and compliance policies and procedures; (f) the
nature, cost and character of non-investment management services pro-
vided by BlackRock and its affiliates; (g) BlackRock’s and other service
providers’ internal controls; (h) BlackRock’s implementation of the proxy
voting policies approved by the Boards; (i) execution quality of portfolio
transactions; (j) BlackRock’s implementation of the Funds’ valuation and
liquidity procedures; and (k) periodic updates on BlackRock’s business.

Board Considerations in Approving the Agreements

The Approval Process: Prior to the April 14, 2009 meeting, each Board
requested and received materials specifically relating to the Agreements.
Each Board is engaged in an ongoing process with BlackRock to continu-
ously review the nature and scope of the information provided to better
assist their deliberations. The materials provided in connection with the
April meeting included (a) information independently compiled and
prepared by Lipper, Inc. (“Lipper”) on Fund fees and expenses, and the
investment performance of each Fund as compared with a peer group of
funds as determined by Lipper and a customized peer group selected by
BlackRock, as applicable (collectively, “Peers”); (b) information on the
profitability of the Agreements to BlackRock and a discussion of fall-out
benefits to BlackRock and its affiliates and significant shareholders;
(c) a general analysis provided by BlackRock concerning investment
advisory fees charged to other clients, such as institutional and open-end
funds, under similar investment mandates, as well as the performance of
such other clients; (d) the impact of economies of scale; (e) a summary
of aggregate amounts paid by each Fund to BlackRock; and (f) an internal
comparison of management fees classified by Lipper, if applicable.

At an in-person meeting held on April 14, 2009, each Board reviewed
materials relating to its consideration of the Agreements. As a result of the
discussions that occurred during the April 14, 2009 meeting, the Boards
presented BlackRock with questions and requests for additional informa-
tion and BlackRock responded to these requests with additional written
information in advance of the May 28 – 29, 2009 Board meeting.

At an in-person meeting held on May 28 – 29, 2009, each Fund’s Board,
including the Independent Board Members, unanimously approved the
continuation of the Advisory Agreement between the Manager and such
Fund and the Sub-Advisory Agreement between such Fund, the Manager
and the Sub-Advisor, each for a one-year term ending June 30, 2010. The
Boards considered all factors they believed relevant with respect to the
Funds, including, among other factors: (a) the nature, extent and quality of
the services provided by BlackRock; (b) the investment performance of the
Funds and BlackRock portfolio management; (c) the advisory fee and the
cost of the services and profits to be realized by BlackRock and certain

affiliates from the relationship with the Funds; (d) economies of scale; and
(e) other factors.

Each Board also considered other matters it deemed important to the
approval process, such as services related to the valuation and pricing of
its respective Fund’s portfolio holdings, direct and indirect benefits to
BlackRock and its affiliates from their relationship with such Fund and
advice from independent legal counsel with respect to the review process
and materials submitted for the Board’s review. The Boards noted the will-
ingness of BlackRock personnel to engage in open, candid discussions
with the Boards. The Boards did not identify any particular information as
controlling, and each Board Member may have attributed different weights
to the various items considered.

A. Nature, Extent and Quality of the Services: Each Board, including its
Independent Board Members, reviewed the nature, extent and quality of
services provided by BlackRock, including the investment advisory services
and the resulting performance of its respective Fund. Throughout the year,
each Board compared its respective Fund’s performance to the perform-
ance of a comparable group of closed-end funds, and the performance of
at least one relevant benchmark, if any. The Boards met with BlackRock’s
senior management personnel responsible for investment operations,
including the senior investment officers. Each Board also reviewed the
materials provided by its respective Fund’s portfolio management team dis-
cussing such Fund’s performance and such Fund’s investment objective,
strategies and outlook.

Each Board considered, among other factors, the number, education and
experience of BlackRock’s investment personnel generally and its respec-
tive Fund’s portfolio management team, investments by portfolio managers
in the funds they manage, BlackRock’s portfolio trading capabilities,
BlackRock’s use of technology, BlackRock’s commitment to compliance
and BlackRock’s approach to training and retaining portfolio managers
and other research, advisory and management personnel. Each Board
also reviewed a general description of BlackRock’s compensation structure
with respect to its respective Fund’s portfolio management team and
BlackRock’s ability to attract and retain high-quality talent.

In addition to advisory services, each Board considered the quality of the
administrative and non-investment advisory services provided to its respec-
tive Fund. BlackRock and its affiliates provide the Funds with certain
administrative and other services (in addition to any such services pro-
vided to the Funds by third parties) and officers and other personnel as
are necessary for the operations of the Funds. In addition to investment
advisory services, BlackRock and its affiliates provide the Funds with
other services, including (i) preparing disclosure documents, such as the
prospectus and the statement of additional information in connection
with the initial public offering and periodic shareholder reports; (ii) prepar-
ing communications with analysts to support secondary market trading of
the Funds; (iii) assisting with daily accounting and pricing; (iv) preparing
periodic filings with regulators and stock exchanges; (v) overseeing and
coordinating the activities of other service providers; (vi) organizing Board

meetings and preparing the materials for such Board meetings; (vii) provid-
ing legal and compliance support; and (viii) performing other administra-
tive functions necessary for the operation of the Funds, such as tax
reporting, fulfilling regulatory filing requirements, and call center services.
The Boards reviewed the structure and duties of BlackRock’s fund adminis-
tration, accounting, legal and compliance departments and considered
BlackRock’s policies and procedures for assuring compliance with applica-
ble laws and regulations.

B. The Investment Performance of the Funds and BlackRock: Each Board,
including its Independent Board Members, also reviewed and considered
the performance history of its respective Fund. In preparation for the April 14,
2009 meeting, the Boards were provided with reports, independently pre-
pared by Lipper, which included a comprehensive analysis of each Fund’s
performance. The Boards also reviewed a narrative and statistical analysis
of the Lipper data that was prepared by BlackRock, which analyzed various
factors that affect Lipper’s rankings. In connection with its review, each
Board received and reviewed information regarding the investment per-
formance of its respective Fund as compared to a representative group
of similar funds as determined by Lipper and to all funds in such Fund’s
applicable Lipper category and customized peer group selected by
BlackRock, as applicable. Each Board was provided with a description of
the methodology used by Lipper to select peer funds. Each Board regularly
reviews the performance of its respective Fund throughout the year.

The Board of MNE noted that MNE performed below the median of its
customized Lipper peer group composite in the three- and five-year periods
reported and MNE performed above the median of its customized Lipper
peer group composite in the one-year period reported. The Board and
BlackRock reviewed the reasons for MNE’s underperformance during these
periods compared with its Peers. The Board was informed that, among
other things, overweight positions in health care and housing credits along
with some poor performance in AMT and Puerto Rico credits negatively
impacted MNE’s performance.

The Board of MYC noted that MYC performed below the median of its cus-
tomized Lipper peer group composite in the three- and five-year periods
reported and MYC performed above the median of its customized Lipper
peer group composite in the one-year period reported. The Board and
BlackRock reviewed the reasons for MYC’s underperformance during these
periods compared with its Peers. The Board was informed that, among
other things, MYC did not have the ability to invest in non-investment grade
securities and, as credit spreads tightened in past years, this negatively
impacted MYC’s performance.

The Board of MYF noted that MYF performed below the median of its
customized Lipper peer group composite in the one-, three- and five-year
periods reported. The Board and BlackRock reviewed the reasons for MYF’s
underperformance during these periods compared with its Peers. The Board
was informed that, among other things, overweight positions in the hospital
and housing sectors and poor performance of some insured and AMT
bonds held by MYF negatively impacted MYF’s performance.

48 ANNUAL REPORT JULY 31, 2009

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (continued)

For MNE, MYC and MYF, the Board of each respective Fund and BlackRock
discussed BlackRock’s commitment to providing the resources necessary to
assist the portfolio managers and to improve each such Fund’s performance.

The Board of MZA noted that in general MZA performed better than its
Peers in that MZA’s performance was at or above the median of its cus-
tomized Lipper peer group composite in each of the one-, three- and five-
year periods reported.

The Board of MYJ noted that in general MYJ performed better than its Peers
in that MYJ’s performance was at or above the median of its Lipper per-
formance universe composite in each of the one-, three- and five-year
periods reported.

C. Consideration of the Advisory Fees and the Cost of the Services
and Profits to be Realized by BlackRock and its Affiliates from their
Relationship with the Funds: Each Board, including its Independent Board
Members, reviewed its respective Fund’s contractual advisory fee rates
compared with the other funds in its respective Lipper category. Each
Board also compared its respective Fund’s total expenses, as well as
actual management fees, to those of other comparable funds. Each Board
considered the services provided and the fees charged by BlackRock to
other types of clients with similar investment mandates, including sepa-
rately managed institutional accounts.

The Boards received and reviewed statements relating to BlackRock’s
financial condition and profitability with respect to the services it provided
the Funds. The Boards were also provided with a profitability analysis that
detailed the revenues earned and the expenses incurred by BlackRock
for services provided to the Funds. The Boards reviewed BlackRock’s prof-
itability with respect to the Funds and other funds the Boards currently
oversee for the year ended December 31, 2008 compared to available
aggregate profitability data provided for the year ended December 31,
2007. The Boards reviewed BlackRock’s profitability with respect to other
fund complexes managed by the Manager and/or its affiliates. The Boards
reviewed BlackRock’s assumptions and methodology of allocating expenses
in the profitability analysis, noting the inherent limitations in allocating
costs among various advisory products. The Boards recognized that prof-
itability may be affected by numerous factors including, among other
things, fee waivers by the Manager, the types of funds managed, expense
allocations and business mix, and therefore comparability of profitability
is somewhat limited.

The Boards noted that, in general, individual fund or product line profitabil-
ity of other advisors is not publicly available. Nevertheless, to the extent
such information is available, the Boards considered BlackRock’s overall
operating margin compared to the operating margin for leading investment
management firms whose operations include advising closed-end funds,
among other product types. The comparison indicated that operating mar-
gins for BlackRock with respect to its registered funds are consistent with
margins earned by similarly situated publicly traded competitors. In addi-
tion, the Boards considered, among other things, certain third-party data
comparing BlackRock’s operating margin with that of other publicly-traded

asset management firms, which concluded that larger asset bases do not,
in themselves, translate to higher profit margins.

In addition, the Boards considered the cost of the services provided to
the Funds by BlackRock, and BlackRock’s and its affiliates’ profits relating
to the management and distribution of the Funds and the other funds
advised by BlackRock and its affiliates. As part of their analysis, the Boards
reviewed BlackRock’s methodology in allocating its costs to the manage-
ment of the Funds. The Boards also considered whether BlackRock has the
financial resources necessary to attract and retain high quality investment
management personnel to perform its obligations under the Agreements
and to continue to provide the high quality of services that is expected by
the Boards.

Each Board noted that its respective Fund paid contractual management
fees, which do not take into account any expense reimbursement or fee
waivers, lower than or equal to the median contractual management fees
paid by such Fund’s Peers.

D. Economies of Scale: Each Board, including its Independent Board
Members, considered the extent to which economies of scale might be
realized as the assets of its respective Fund increase and whether there
should be changes in the advisory fee rate or structure in order to enable
such Fund to participate in these economies of scale, for example through
the use of breakpoints in the advisory fee based upon the assets of such
Fund. The Boards considered that the funds in the BlackRock fund complex
share some common resources and, as a result, an increase in the overall
size of the complex could permit each fund to incur lower expenses than
it would otherwise as a stand-alone entity. The Boards also considered
BlackRock’s overall operations and its efforts to expand the scale of, and
improve the quality of, its operations.

The Boards noted that most closed-end fund complexes do not have fund
level breakpoints because closed-end funds generally do not experience
substantial growth after the initial public offering and each fund is man-
aged independently consistent with its own investment objectives. The
Boards noted that only one closed-end fund in the Fund Complex has
breakpoints in its fee structure. Information provided by Lipper also
revealed that only one closed-end fund complex used a complex-level
breakpoint structure.

E. Other Factors: The Boards also took into account other ancillary or
“fall-out” benefits that BlackRock or its affiliates and significant sharehold-
ers may derive from their relationship with the Funds, both tangible and
intangible, such as BlackRock’s ability to leverage its investment profes-
sionals who manage other portfolios, an increase in BlackRock’s profile in
the investment advisory community, and the engagement of BlackRock’s
affiliates as service providers to the Funds, including for administrative
and distribution services. The Boards also noted that BlackRock may use
third-party research obtained by soft dollars generated by certain mutual
fund transactions to assist itself in managing all or a number of its other
client accounts.

ANNUAL REPORT JULY 31, 2009 49

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (concluded)

In connection with their consideration of the Agreements, the Boards also
received information regarding BlackRock’s brokerage and soft dollar prac-
tices. The Boards received reports from BlackRock, which included informa-
tion on brokerage commissions and trade execution practices throughout
the year.

Conclusion

Each Board, including its Independent Board Members, unanimously
approved the continuation of the Advisory Agreement between its respec-
tive Fund and the Manager for a one-year term ending June 30, 2010
and the Sub-Advisory Agreement between such Fund, the Manager and
Sub-Advisor for a one-year term ending June 30, 2010. Based upon its
evaluation of all these factors in their totality, each Board, including its
Independent Board Members, was satisfied that the terms of the Agreements

were fair and reasonable and in the best interest of its respective Fund and
its shareholders. In arriving at a decision to approve the Agreements, each
Board did not identify any single factor or group of factors as all-important
or controlling, but considered all factors together, and different Board
Members may have attributed different weights to the various factors con-
sidered. The Independent Board Members were also assisted by the advice
of independent legal counsel in making this determination. The contractual
fee arrangements for each Fund reflects the results of several years of
review by such Fund’s Board Members and predecessor Board Members,
and discussions between such Board Members (and predecessor Board
Members) and BlackRock. Certain aspects of the arrangements may be
the subject of more attention in some years than in others, and the Board
Members’ conclusions may be based in part on their consideration of these
arrangements in prior years.

50 ANNUAL REPORT JULY 31, 2009

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 a
Fund are automatically reinvested in additional Common Shares of the
Fund. The Plan is administered on behalf of the shareholders by The BNY
Mellon Shareowner Services for BlackRock MuniYield Arizona Fund, Inc.,
BlackRock MuniYield California Fund, Inc., BlackRock MuniYield Investment
Fund and BlackRock MuniYield New Jersey Fund, Inc., and Computershare
Trust Company, N.A. for BlackRock Muni New York Intermediate Duration
Fund, Inc. (individually, the “Plan Agent” or together, the “Plan Agents”).
Under the Plan, whenever a Fund declares a dividend, participants in the
Plan will receive the equivalent in shares of Common Shares of the Fund.
The Plan Agents will acquire the shares for the participant’s account either
(i) through receipt of additional unissued but authorized shares of the
Funds (“newly issued shares”) or (ii) by purchase of outstanding Common
Shares on the open market on the New York Stock Exchange or NYSE
Amex, as applicable or elsewhere. If, on the dividend payment date, the
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 Fund’s 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 pur-
chasing 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
Common Shares 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 mar-
ket price plus commissions of a 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 distribu-
tions in shares at prices below the net asset value. Also, since the Funds
do 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 participat-
ing 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 distribu-
tions 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. 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 possi-
ble that all or a portion of the discount from the market value (which may
not exceed 5% of the fair market value of the Funds’ 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 dis-
tributions 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
following addresses: Shareholders of BlackRock MuniYield Arizona Fund,

Additional Information

General Information

The Funds do not make available copies of their Statements of Additional
Information because the Funds’ shares are not continuously offered, which
means that the Statement of Additional Information of each Fund has not
been updated after completion of the respective Fund’s offerings and the
information contained in each Fund’s Statement of Additional Information
may have become outdated.

Other than the revisions discussed in the Board Approvals on page 57,
there were no material changes in the Funds’ investment objectives or poli-
cies or to the Funds’ charters or by-laws that were not approved by their
shareholders or in the principal risk factors associated with investment in
the Funds. There have been no changes in the persons who are primarily
responsible for the day-to-day management for the Funds’ portfolios.

Quarterly performance, semi-annual and annual reports and other informa-
tion regarding the Funds may be found on BlackRock’s website, which can
be accessed at http://www.blackrock.com. This reference to BlackRock’s
website is intended to allow investors public access to information regard-
ing the Funds and does not, and is not intended to, incorporate BlackRock’s
website into this report.

Electronic Delivery

Electronic copies of most financial reports are available on the Funds’ web-
sites or shareholders can sign up for e-mail notifications of quarterly state-
ments, annual and semi-annual reports by enrolling in the Funds’ electronic
delivery program.

Shareholders Who Hold Accounts with Investment Advisors, Banks
or Brokerages:

Please contact your financial advisor to enroll. Please note that not all
investment advisors, banks or brokerages may offer this service.

Householding

The Funds will mail only one copy of shareholder documents, including
annual and semi-annual reports and proxy statements, to shareholders
with multiple accounts at the same address. This practice is commonly
called “householding” and it is intended to reduce expenses and eliminate
duplicate mailings of shareholder documents. Mailings of your shareholder
documents may be householded indefinitely unless you instruct us other-
wise. If you do not want the mailing of these documents to be combined
with those for other members of your household, please contact the Funds
at (800) 441-7762.

Availability of Quarterly Schedule of Investments

Each Fund files its complete schedule of portfolio holdings witht the SEC
for the first and third quarters of each fiscal year on Form N-Q. The Funds’

may also be reviewed and copied at the SEC’s Public Reference Room

Additional Information (continued)

Dividend Policy

The Funds’ dividend policy is to distribute all or a portion of their net
investment income to its shareholders on a monthly basis. In order to pro-
vide shareholders with a more stable level of dividend distributions, the
Funds may at times pay out less than the entire amount of net investment
income earned in any particular month and may at times in any particular
month pay out such accumulated but undistributed income in addition to

net investment income earned in that month. As a result, the dividends
paid by the Funds for any particular month may be more or less than the
amount of net investment income earned by the Funds during such month.
The Funds’ current accumulated but undistributed net investment income, if
any, is disclosed in the Statements of Assets and Liabilities, which com-
prises part of the financial information included in this report.

Fund Certification

Certain Funds are listed for trading on the New York Stock Exchange
(“NYSE”) and have filed with the NYSE their annual chief executive officer
certification regarding compliance with the NYSE’s listing standards. The

Funds filed with the SEC the certification of its chief executive officer and
chief financial officer required by section 302 of the Sarbanes-Oxley Act.

Board Approvals

On September 12, 2008, the Board of Directors of BlackRock MuniYield
Florida Fund voted unanimously to change a non-fundamental invest-
ment policy of the Fund, and to rename the Fund “BlackRock MuniYield
Investment Fund.” The Fund’s previous non-fundamental investment policy
required the Fund, under normal market conditions, to invest at least 80%
of its assets in Florida municipal bonds and 100% in municipal bonds
rated investment grade at time of investment. Due to the repeal of the
Florida Intangible Personal Property Tax as of January 2007, the Board
has approved an amended policy allowing the Fund flexibility to invest in
municipal obligations regardless of geographic location. The Fund’s new
investment policy is, under normal market conditions, to invest 100% of its
assets in municipal bonds rated investment grade at time of investment.
The approved changes will not alter the Fund’s investment objective.

Under current market conditions, the Manager anticipates that it will gradu-
ally reposition the Fund’s portfolio over time and that during such period
the Fund may continue to hold a substantial portion of its assets in Florida
municipal bonds. At this time, it is uncertain how long the repositioning
may take, and the Fund will continue to be subject to risks associated with

investing a substantial portion of its assets in Florida municipal bonds until
the repositioning is complete.

The Manager and the Board believe the amended policy will allow the
Manager to better manage the Fund’s portfolio in the best interests of Fund
shareholders and to better meet the Fund’s investment objective.

Effective September 13, 2008, following approval by the Funds’ Board
and the applicable ratings agencies, the Board amended the terms of
the Funds’ Articles Supplementary in order to allow the Funds to enter
into TOB transactions, the proceeds of which were used to redeem a
portion of the Funds’ Preferred Shares. Accordingly, the definition of
Inverse Floaters was amended to incorporate the Funds’ permissible
ratio of floating rate instruments into inverse floating rate instruments.
Additionally, conforming changes and certain formula modifications con-
cerning inverse floaters were made to the definitions of Moody’s Discount
Factor and S&P Discount Factor, as applicable, to integrate the Funds’
investments in TOBs into applicable calculations.

58 ANNUAL REPORT JULY 31, 2009


This report is transmitted to shareholders only. It is not a prospectus. Past performance results shown in this report should not be considered a representa-
tion of future performance. The Funds have leveraged their Common Shares which creates risks for Common Shareholders, including the likelihood of greater
volatility of net asset value and market price of the Common Shares, and the risk that fluctuations in the short-term dividend rates of the Preferred Shares,
currently set at the maximum reset rate as a result of failed auctions, may affect the yield to Common Shareholders. Statements and other information
herein are as dated and are subject to change.


Item 2 – Code of Ethics – The registrant (or the “Fund”) has adopted a code of ethics, as of the end of the
period covered by this report, applicable to the registrant’s principal executive officer, principal
financial officer and principal accounting officer, or persons performing similar functions. During
the period covered by this report, there have been no amendments to or waivers granted under the
code of ethics. A copy of the code of ethics is available without charge at www.blackrock.com.

Item 3 – Audit Committee Financial Expert – The registrant’s board of directors or trustees, as applicable
(the “board of directors”) has determined that (i) the registrant has the following audit committee
financial experts serving on its audit committee and (ii) each audit committee financial expert is
independent:
Kent Dixon
Frank J. Fabozzi
James T. Flynn
W. Carl Kester
Karen P. Robards
Robert S. Salomon, Jr. (retired effective December 31, 2008)

The registrant’s board of directors has determined that W. Carl Kester and Karen P. Robards qualify
as financial experts pursuant to Item 3(c)(4) of Form N-CSR.

Prof. Kester has a thorough understanding of generally accepted accounting principles, financial
statements and internal control over financial reporting as well as audit committee functions. Prof.
Kester has been involved in providing valuation and other financial consulting services to corporate
clients since 1978. Prof. Kester’s financial consulting services present a breadth and level of
complexity of accounting issues that are generally comparable to the breadth and complexity of
issues that can reasonably be expected to be raised by the registrant’s financial statements.

Ms. Robards has a thorough understanding of generally accepted accounting principles, financial
statements and internal control over financial reporting as well as audit committee functions. Ms.
Robards has been President of Robards & Company, a financial advisory firm, since 1987. Ms.
Robards was formerly an investment banker for more than 10 years where she was responsible for
evaluating and assessing the performance of companies based on their financial results. Ms.
Robards has over 30 years of experience analyzing financial statements. She also is a member of
the audit committee of one publicly held company and a non-profit organization.

Under applicable securities laws, a person determined to be an audit committee financial expert will
not be deemed an “expert” for any purpose, including without limitation for the purposes of Section
11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee
financial expert. The designation or identification as an audit committee financial expert does not
impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and
liabilities imposed on such person as a member of the audit committee and board of directors in the
absence of such designation or identification.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:
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 provided to the registrant and those non-audit services
provided to the 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”). The
term of any general pre-approval is 12 months from the date of the pre-approval, unless the
Committee provides for a different period. Tax or other non-audit services provided to the registrant
which have a direct impact on the operation or financial reporting of the registrant will only be
deemed pre-approved provided that any individual project does not exceed $10,000 attributable to
the registrant or $50,000 for all of the registrants the Committee oversees. For this purpose,
multiple projects will be aggregated to determine if they exceed the previously mentioned cost
levels.
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. At this
meeting, an analysis of such services is presented to the Committee for ratification. The Committee
may delegate to one or more of its members the authority to approve the provision of and fees for
any specific engagement of permitted non-audit services, including services exceeding pre-approved
cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by the audit
committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g) Affiliates’ Aggregate Non-Audit Fees:

  Current Fiscal Year  Previous Fiscal Year 
Entity Name  End  End 

BlackRock MuniYield     
California Fund, Inc.  $418,128  $415,649 

(h) The registrant’s audit committee has considered and determined that the provision of non-audit
services that were rendered to the registrant’s investment adviser (not including any non-affiliated
sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by
the registrant’s investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the registrant that were not
pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with
maintaining the principal accountant’s independence.

Regulation S-X Rule 2-01(c)(7)(ii) – $407,500, 0%

Item 5 – Audit Committee of Listed Registrants – The following individuals are members of the registrant’s
separately-designated standing audit committee established in accordance with Section 3(a)(58)(A)
of the Securities Exchange Act of 1934 (15 U.S.C. 78c(a)(58)(A)):

Kent Dixon
Frank J. Fabozzi
James T. Flynn
W. Carl Kester
Karen P. Robards
Robert S. Salomon, Jr. (retired effective December 31, 2008)

Item 6 – Investments
(a) The registrant’s Schedule of Investments is included as part of the Report to Stockholders filed
under Item 1 of this form.
(b) Not Applicable due to no such divestments during the semi-annual period covered since the
previous Form N-CSR filing.

Item 7 – Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment
Companies – The board of directors has delegated the voting of proxies for the Fund securities to the
Fund’s investment adviser (“Investment Adviser”) pursuant to the Investment Adviser’s proxy
voting guidelines. Under these guidelines, the Investment Adviser will vote proxies related to Fund
securities in the best interests of the Fund and its stockholders. From time to time, a vote may
present a conflict between the interests of the Fund’s stockholders, on the one hand, and those of the
Investment Adviser, or any affiliated person of the Fund or the Investment Adviser, on the other. In
such event, provided that the Investment Adviser’s Equity Investment Policy Oversight Committee,
or a sub-committee thereof (the “Oversight Committee”) is aware of the real or potential conflict or
material non-routine matter and if the Oversight Committee does not reasonably believe it is able to
follow its general voting guidelines (or if the particular proxy matter is not addressed in the
guidelines) and vote impartially, the Oversight Committee may retain an independent fiduciary to
advise the Oversight Committee on how to vote or to cast votes on behalf of the Investment
Adviser’s clients. If the Investment Adviser determines not to retain an independent fiduciary, or
does not desire to follow the advice of such independent fiduciary, the Oversight Committee shall
determine how to vote the proxy after consulting with the Investment Adviser’s Portfolio
Management Group and/or the Investment Adviser’s Legal and Compliance Department and

concluding that the vote cast is in its client’s best interest notwithstanding the conflict. A copy of the
Fund’s Proxy Voting Policy and Procedures are attached as Exhibit 99.PROXYPOL. Information on
how the Fund voted proxies relating to portfolio securities during the most recent 12-month period
ended June 30 is available without charge, (i) at www.blackrock.com and (ii) on the SEC’s website

           (iv) Potential Material Conflicts of Interest         

BlackRock and its affiliates (collectively, herein “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 significant shareholders 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 significant shareholders, 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’ or significant shareholders’) officers, directors or employees are
directors or officers, or companies as to which BlackRock or any of its affiliates or significant
shareholders 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 a fund. In
this connection, it should be noted that a portfolio manager may currently manage certain accounts
that are subject to performance fees. In addition, a portfolio manager may 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 July 31, 2009:

Portfolio Manager Compensation Overview

BlackRock’s financial arrangements with its portfolio managers, its competitive compensation and
its career path emphasis at all levels reflect the value senior management places on key resources.
Compensation may include a variety of components and may vary from year to year based on a
number of factors. The principal components of compensation include a base salary, a performance-
based discretionary bonus, participation in various benefits programs and one or more of the
incentive compensation programs established by BlackRock such as its Long-Term Retention and
Incentive Plan.

Base compensation. Generally, portfolio managers receive base compensation based on their
seniority and/or their position with the firm. Senior portfolio managers who perform additional
management functions within the portfolio management group or within BlackRock may receive
additional compensation for serving in these other capacities.

Discretionary Incentive Compensation
Discretionary incentive compensation is a function of several components: the performance of
BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the
investment performance, including risk-adjusted returns, of the firm’s assets under management or
supervision by that portfolio manager relative to predetermined benchmarks, and the individual’s
seniority, role within the portfolio management team, teamwork and contribution to the overall
performance of these portfolios and BlackRock. In most cases, including for the portfolio managers
of the Fund, these benchmarks are the same as the benchmark or benchmarks against which the
performance of the Fund or other accounts managed by the portfolio managers are measured.
BlackRock’s Chief Investment Officers determine the benchmarks against which the performance of
funds and other accounts managed by each portfolio manager is compared and the period of time
over which performance is evaluated. With respect to the portfolio managers, such benchmarks for
the Fund include a combination of market-based indices (e.g. Barclays Capital Municipal Bond
Index), certain customized indices and certain fund industry peer groups.

BlackRock’s Chief Investment Officers make a subjective determination with respect to the
portfolio managers’ compensation based on the performance of the funds and other accounts
managed by each portfolio manager relative to the various benchmarks noted above. Performance is
measured on both a pre-tax and after-tax basis over various time periods including 1, 3, 5 and 10-
year periods, as applicable.

Distribution of Discretionary Incentive Compensation
Discretionary incentive compensation is distributed to portfolio managers in a combination of cash
and BlackRock, Inc. restricted stock units which vest ratably over a number of years. The
BlackRock, Inc. restricted stock units, if properly vested, will be settled in BlackRock, Inc. common
stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of
total compensation for the portfolio managers. Paying a portion of annual bonuses in stock puts
compensation earned by a portfolio manager for a given year “at risk” based on BlackRock’s ability
to sustain and improve its performance over future periods.

Long-Term Retention and Incentive Plan (“LTIP”) — The LTIP is a long-term incentive
plan that seeks to reward certain key employees. Beginning in 2006, awards are granted under the
LTIP in the form of BlackRock, Inc. restricted stock units that, if properly vested and subject to the
attainment of certain performance goals, will be settled in BlackRock, Inc. common stock. Messrs.
O’Connor and Jaeckel have each received awards under the LTIP.

Deferred Compensation Program — A portion of the compensation paid to eligible
BlackRock employees may be voluntarily deferred into an account that tracks the performance of
certain of the firm’s investment products. Each participant in the deferred compensation program is
permitted to allocate his deferred amounts among the various investment options. Messrs.
O’Connor and Jaeckel have each participated in the deferred compensation program.

Other compensation benefits. In addition to base compensation and discretionary incentive
compensation, portfolio managers may be eligible to receive or participate in one or more of the
following:

Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which
BlackRock employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement
Savings Plan (RSP), and the BlackRock Employee Stock Purchase Plan (ESPP). The employer
contribution components of the RSP include a company match equal to 50% of the first 6% of
eligible pay contributed to the plan capped at $4,000 per year, and a company retirement
contribution equal to 3-5% of eligible compensation. The RSP offers a range of investment options,
including registered investment companies managed by the firm. BlackRock contributions follow
the investment direction set by participants for their own contributions or, absent employee
investment direction, are invested into a balanced portfolio. The ESPP allows for investment in
BlackRock common stock at a 5% discount on the fair market value of the stock on the purchase
date. Annual participation in the ESPP is limited to the purchase of 1,000 shares or a dollar value of
$25,000. Each portfolio manager is eligible to participate in these plans.
