Dear Shareholder

The global economy is continuing to slowly improve, with the United States and emerging markets leading the way; however global and US economic

statistics show that the pace of economic growth has trailed off in recent months. Market volatility has remained elevated over the past several months as

investors remain uncertain about the future direction of economic growth. The sovereign debt crisis in Europe, slowing growth in China and concerns over

the possibility that the United States and other developed markets are heading for a double-dip recession have all acted to depress investor sentiment. It

is our view that the recent soft patch of economic data is just that — a slowdown in the pace of recovery and not an indication that the economy is sliding

back into recession. In the United States, we expect to see slightly slower economic growth over the next several quarters; however, true double-dip

recessions are quite rare, and unless there is a major shock to the economy, we believe the recovery will continue.

Global equity markets have moved unevenly higher since bottoming out in early 2009 as investors were enticed by depressed valuations, improved corp-

orate earnings, and their desire for higher yields. Several significant downturns, however, have occurred — primarily as a result of mixed economic data and

concerns about the possibility of prolonged deflation (especially in Europe). As the period drew to a close, equity markets were staging a muted recovery.

On a 12-month basis global equities were still showing positive returns thanks to improving corporate revenues and profits and a reasonably strong macro

backdrop. From a geographic perspective, US equities have significantly outpaced their international counterparts over the past six and twelve months, as

the domestic economic recovery has been more pronounced and credit-related issues have held European markets down. Within the United States, smaller

cap stocks have outperformed large caps year-to-date.

In fixed income markets, yields have fluctuated significantly over the past year as economic data has been mixed. Over recent months, risk aversion and

credit issues kept interest rates low and US Treasury yields have fallen significantly as investors favored “safe haven” assets. As the period drew to a close,

higher-risk fixed income assets performed well due to strong earnings announcements and better-than-expected results on European bank stress tests.

Meanwhile, tax-exempt municipal bonds slightly outperformed US investment grade bonds on a 12-month basis, but underperformed year-to-date as

investors rotated to the relative safety of Treasuries.

Regarding cash investments, yields on money market securities remain near all-time lows (producing returns only marginally above zero percent), with

the Federal Open Market Committee reiterating that economic circumstances are likely to necessitate an accommodative interest rate stance for an

“extended period.”

 

Past performance is no guarantee of future results. Index performance shown for illustrative purposes only. You cannot invest directly in an index.

Although conditions are certainly better than they were a couple of years ago, global financial markets continue to face high volatility while questions about
the strength and sustainability of the recovery abound. Through periods of uncertainty, as ever, BlackRock’s full resources are dedicated to the management
of our clients’ assets. For additional market perspective and investment insight, visit www.blackrock.com/shareholdermagazine , where you’ll find the most

Fund Summary as of July 31, 2010

BlackRock Muni New York Intermediate Duration Fund, Inc.

Fund Overview

BlackRock Muni New York Intermediate Duration Fund, Inc.’s (MNE) (the “Fund”) investment objective is to provide Common Shareholders with high
current income exempt from federal income tax and New York State and New York City personal income taxes. The Fund seeks to achieve its investment
objective by investing at least 80% of its assets in municipal obligations exempt from federal income tax (except that the interest may be subject to the fed-
eral alternative minimum tax) and New York State and New York City personal income taxes. Under normal market conditions, the Fund invests at least 75%
of its assets in municipal obligations that are investment grade quality at the time of investment. Under normal market conditions, the Fund invests at least
80% of its assets in municipal obligations with a duration of three to ten years. The Fund may invest directly in such securities or synthetically through the
use of derivatives.
No assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the 12 months ended July 31, 2010, the Fund returned 23.05% based on market price, and 17.67% based on net asset value (“NAV”). For the same
period, the closed-end Lipper Intermediate Municipal Debt Funds category posted an average return of 20.59% based on market price, and 14.73% based
on NAV. 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 market price and performance based on NAV. The following discussion relates to performance based on NAV. The Fund’s outper-
formance relative to its peer group resulted more from its price appreciation than from its distributions, which were below the peer group average for the
period. The Fund’s concentration in longer-dated issues within its intermediate duration mandate benefited performance during the period. On average, the
Fund had a neutral-to-positive duration bias over the period. This positioning along with a low cash balance resulted in positive capital appreciation. Overall
the tax-exempt municipal market benefited from the Build America Bond Program, which made the taxable market accessible to municipal issuers. This
alleviated supply pressure in the tax-exempt space, which, coupled with increased investor demand for municipals, resulted in a favorable supply-demand
paradigm and strong performance. Many of the Fund’s holdings had depressed valuations resulting from their underperformance during dislocations in the
credit market, which expanded their upside potential as the market recovered. We purchased a number of new issues structured with the goal of creating
greater potential for price appreciation in response to declining interest rates. The Fund’s exposure to the health and housing sectors and Puerto Rico
credits also added to performance. Detracting from performance was the Fund’s exposure to the transportation sector and the short-term, high-grade,
pre-refunded sector.

Fund Summary as of July 31, 2010

BlackRock MuniYield Arizona Fund, Inc.

Fund Overview

BlackRock MuniYield Arizona Fund, Inc.’s (MZA) (the “Fund”) investment objective is 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. The Fund seeks to achieve its invest-
ment objective by investing at least 80% of its assets in municipal obligations exempt from federal income taxes (except that the interest may be subject to
the federal alternative minimum tax) and Arizona income taxes. Under normal market conditions, the Fund expects to invest at least 75% of its assets in
municipal obligations that are investment grade quality at the time of investment. The Fund may invest directly in such securities or synthetically through the
use of derivatives.

No assurance can be given that the Fund’s investment objective will be achieved.

Performance

For the 12 months ended July 31, 2010, the Fund returned 13.13% based on market price, and 17.75% based on NAV. For the same period, the closed-
end Lipper Other States Municipal Debt Funds category posted an average return of 19.82% based on market price, and 14.58% based on NAV. All returns
reflect reinvestment of dividends. The Fund moved from a premium to NAV to a slight discount by period end, which accounts for the difference between
performance based on market price and performance based on NAV. The following discussion relates to performance based on NAV. The Fund benefited
from its modestly positive positioning as interest rates declined over the period. The Fund’s exposure to the long-end of the yield curve made a positive
impact as prices of longer-dated bonds are most sensitive to declining interest rates. The Fund’s holdings of lower-rated issues also aided results as credit
quality spreads tightened over the period. Detracting from performance was the Fund’s exposure to zero-coupon bonds, which underperformed relative to
the broader municipal bond market as spreads in this sector generally widened. The Fund’s exposure to bonds with shorter maturities and bonds that price
to shorter calls also detracted as declining rates had less of an impact on the shorter end of the yield curve.

The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These

end Lipper California Municipal Debt Funds category posted an average return of 22.90% based on market price, and 18.98% based on NAV. 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
market price and performance based on NAV. The following discussion relates to performance based on NAV. The Fund’s neutral duration stance during the
first half of the period hindered performance as interest rates were generally declining; however, shifting to a more aggressive duration stance in the second
half of the period proved beneficial. Declining interest rates also had a negative impact on short-call, high-coupon bonds held in the Fund during the first
half of the period. On the positive side, the Fund’s fully invested posture and relatively high degree of income accrual contributed to performance. The
tightening of credit quality spreads boosted performance of the lower-rated sectors of the portfolio. The Fund’s holdings in corporate-backed and health
municipals also aided performance.

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 financing 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 each Fund (including the assets obtained
from leverage) are invested in higher-yielding portfolio investments, each
Fund’s Common Shareholders will benefit from the incremental net income.

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 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.

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, if
prevailing short-term interest rates rise above long-term interest 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.

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 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 each Fund’s 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. Each Fund
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 a Fund to incur losses. The use of leverage may limit each
Fund’s 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 the Funds. Each
Fund will incur expenses in connection with the use of leverage, all of
which are borne by Common Shareholders and may reduce income to
the Common Shares.

Under the Investment Company Act of 1940, the Funds are permitted to
issue Preferred Shares in an amount of up to 50% of their total managed
assets at the time of issuance. Under normal circumstances, each Fund
anticipates that the total economic leverage from Preferred Shares and/or
TOBs will not exceed 50% of its total managed assets at the time such
leverage is incurred. As of July 31, 2010, the Funds had economic leverage
from Preferred Shares and/or TOBs as a percentage of their total managed
assets as follows:

 

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 may constitute forms of economic leverage. Such instru-
ments 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,
possible default of the counterparty to the transaction or illiquidity of the
derivative instrument. Each Fund’s 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, may result in lower dividends
paid to shareholders, or may cause a Fund to hold a security that it might
otherwise sell. The Funds’ investments in these instruments are discussed
in detail in the Notes to Financial Statements.

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
Series’ own assumptions used in determining the fair value of investments

Notes to Financial Statements

1. Organization and Significant Accounting Policies:

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”) (collec-
tively, the “Funds” or individually as a “Fund”) are registered under the
Investment Company Act of 1940, as amended (the “1940 Act”), as non-
diversified, closed-end management investment companies. MNE, MZA,
MYC and MYJ are organized as Maryland corporations. MYF is organized as
a Massachusetts business trust. The Funds' financial statements are pre-
pared in conformity with accounting principles generally accepted in the
United States of America ("US GAAP"), which may require management to
make estimates and assumptions that affect the reported amounts and
disclosures in the financial statements. Actual results could differ from
those estimates. The Funds determine and make available for publication
the net asset value of their Common Shares on a daily basis.

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

Valuation: The Funds fair value their financial instruments at market value
using independent dealers or pricing services under policies approved by
each Fund’s Board of Directors/Trustees (the “Board”). Municipal invest-
ments (including commitments to purchase such investments on a “when-
issued” basis) are valued on the basis of prices provided by dealers or
pricing services. In determining the value of a particular investment, pricing
services may use certain information with respect to transactions in such
investments, quotations from dealers, pricing matrixes, market transactions
in comparable investments and information with respect to various rela-
tionships between investments. Financial futures contracts traded on
exchanges are valued at their last sale price. Short-term securities with
remaining maturities of 60 days or less may be valued at amortized cost,
which approximates fair value. Investments in open-end investment compa-
nies 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 or is not available, the investment will be
valued in accordance with a policy approved by the 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 cur-
rent sale of that asset in an arm’s-length transaction. Fair value determina-
tions 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 con-
ditions 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 deliv-
ery basis, the Funds assume the rights and risks of ownership of the secu-
rity, 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
appreciation of unsettled when-issued transactions, which is shown on the
Schedules of Investments, if any.

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 a Fund (1) to cause the holders of a proportional
share of the short-term floating rate certificates to tender their certificates
at par, including during instances of a rise in short-term interest rates and
(2) to transfer, within seven days, a corresponding share of the municipal
bonds from the TOB to a Fund. The TOB may also be terminated without the
consent of a 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 a 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 municipal bonds is recorded by the
Funds on an accrual basis. Interest expense incurred on the secured bor-
rowing and other expenses related to remarketing, administration and
trustee services to a TOB are shown as interest expense and fees in the
Statements of Operations. The short-term 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, 2010, the aggregate value of the underlying municipal bonds

Notes to Financial Statements (continued)

transferred to TOBs, the related liability for trust certificates and the range
of interest rates on the liability for trust certificates were as follows:

 

For the year ended July 31, 2010, the Funds' average trust certificates
outstanding and the daily weighted average interest rate, including fees,
were as follows:

 

Should short-term interest rates rise, the Funds' investments in TOBs may
adversely affect the Funds' net investment 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 values
per share.

Zero-Coupon Bonds: The Funds 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 the Funds either deliver collateral or segregate assets in con-
nection with certain investments (e.g., financial futures contracts), each
Fund will, consistent with SEC rules and/or certain interpretive letters
issued by the SEC, segregate collateral or designate on their 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 segre-
gated. 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.

Investment Transactions and Investment Income: For financial reporting
purposes, investment transactions are recorded on the dates the transac-
tions are entered into (the trade dates). Realized gains and losses on
investment transactions are determined on the identified cost basis.
Interest income, including amortization of premium and accretion of
discount on debt securities, is recognized on the accrual basis.

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 of 1986, as amended, 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 each of the
four periods ended as follows:

 

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

Deferred Compensation and BlackRock Closed-End Share Equivalent
Investment Plan: Under the deferred compensation plan approved by each
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 its deferred compensation obligations. Investments to
cover each Fund's deferred compensation liability, if any, are included in
other assets in the Statements of Assets and Liabilities. Dividends and dis-
tributions from the BlackRock Closed-End Fund investments under the plan
are included in income — affiliated in the Statements of Operations.

Other: Expenses directly related to a Fund are charged to that Fund. Other
operating expenses shared by several funds are pro rated among those
funds on the basis of relative net assets or other appropriate methods.
The Funds have an arrangement with their custodians whereby fees may
be reduced by credits earned on uninvested cash balances, which, if
applicable, are shown as fees paid indirectly in the Statements of

38 ANNUAL REPORT

JULY 31, 2010

---

Notes to Financial Statements (continued)

Operations. The custodians impose fees on overdrawn cash balances,
which can be offset by accumulated credits earned or may result in
additional custody charges.

2. Derivative Financial Instruments:

The Funds engage in various portfolio investment strategies using derivative
contracts both to increase the returns of the Funds and to economically
hedge, or protect, their exposure to certain risks such as interest rate risk.
These contracts may be transacted on an exchange.

Losses may arise if the value of the contract decreases due to an unfav-
orable change in the market rates or value of the underlying instrument
or if the counterparty does not perform under the contract. Counterparty
risk related to exchange-traded financial futures contracts is minimal
because of the protections against defaults provided by the exchange
on which they trade.

Financial Futures Contracts: The Funds purchase or sell financial futures
contracts and options on financial futures contracts to gain exposure to, or
economically hedge against, changes in interest rates (interest rate risk).
Financial futures contracts are contracts for delayed delivery of securities

or currencies 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 finan-
cial futures contracts, interest rates and the underlying assets.

 

The Effect of Derivative Instruments on the Statements of Operations

Year Ended July 31, 2010

 

For the year ended July 31, 2010, the average quarterly balance of outstanding derivative financial instruments was as follows:

 

3. Investment Advisory Agreement and Other Transactions
with Affiliates:

The PNC Financial Services Group, Inc. ("PNC"), Bank of America
Corporation ("BAC") and Barclays Bank PLC ("Barclays") are the largest
stockholders of BlackRock, Inc. ("BlackRock"). Due to the ownership struc-
ture, PNC is an affiliate of the Funds for 1940 Act purposes, but BAC and
Barclays are not.

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, each Fund pays the Manager a monthly fee at the
following annual rates of each Fund's average daily net assets as follows:

 

Average daily net assets is the average daily value of each Fund’s total
assets minus the sum of its accrued liabilities.

The Manager contractually agreed to waive a portion of its fee during the
first seven years of MNE’s operations ending July 31, 2010. For the year
ended July 31, 2010, the Manager waived advisory fees in the amount of

of Operations.

Notes to Financial Statements (continued)

The Manager voluntarily agreed to waive its investment advisory fees by the
amount of investment advisory fees each Fund pays to the Manager indi-
rectly through its investment in affiliated money market funds; however, the
Manager does not waive its investment advisory fees by the amount of
investment advisory fees paid through each Fund’s investment in other
affiliated investment companies, if any. These amounts are shown as, or
included in, fees waived by advisor in the Statements of Operations. For
the year ended July 31, 2010, the amounts waived were as follows:

 

The Manager entered into a sub-advisory agreement with BlackRock
Investment Management, LLC (“BIM”), an affiliate of the Manager. The
Manager pays BIM for services it provides, a monthly fee that is a percent-
age of the investment advisory fees paid by each Fund to the Manager.

For the year ended July 31, 2010, each Fund reimbursed the Manager for
certain accounting services, which are included in accounting services in
the Statements of Operations. The reimbursements were as follows:

 

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, 2010, were as follows:

 

5. Income Tax Information:

Reclassifications: US GAAP 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, 2010 attributable to
amortization methods on fixed income securities were reclassified to the following accounts:

 

* The differences between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on straddles, the difference between book and tax for
premiums and discounts on fixed income securities, the realization for tax purposes of unrealized gains/losses on certain futures contracts, the deferral of post-October capital
losses for tax purposes, and the treatment of residual interests in tender option bond trusts.

Notes to Financial Statements (continued)

As of July 31, 2010, the Funds had capital loss carryforwards available to offset future realized capital gains through the indicated expiration dates:

 

6. Concentration, Market and Credit Risk:

MNE, MZA, MYC and MYJ invest a substantial amount of their 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 may reduce
the potential for loss due to credit risk. 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 (issuer
credit risk). The value of securities held by the Funds may decline in
response to certain events, including those directly involving the issuers
whose securities are owned by the Funds; conditions affecting the general
economy; overall market changes; local, regional or global political, social
or economic instability; and currency and interest rate and price fluctua-
tions. Similar to issuer credit risk, the Funds may be exposed to counter-
party credit risk, or the risk that an entity with which the Funds have
unsettled or open transactions may fail to or be unable to perform on its
commitments. The Funds manage counterparty credit risk by entering into
transactions only with counterparties that they believe have the financial
resources to honor their obligations and by monitoring the financial stability
of those counterparties. Financial assets, which potentially expose the
Funds to market, issuer and counterparty credit risks, consist principally of
financial instruments and receivables due from counterparties. The extent
of the Funds' exposure to market, issuer and counterparty credit risks with
respect to these financial assets is generally approximated by their value
recorded in the Funds' Statements of Assets and Liabilities, less any collat-
eral held by the Funds.

MZA and MYC invest a significant portion of their assets in the County/
City/Special District/School District and Utilities sectors. MYF invests a
significant portion of its assets in securities in the County/City/Special
District/School District, Transportation and Health sectors. MYJ invests a
significant portion of its assets in securities in the State sector. Changes
in economic conditions affecting the County/City/Special District/School
District, Health, State, Transportation and Utilities sectors would have a
greater impact on the Funds, and could affect the value, income and/or
liquidity of positions in such securities.

7. Capital Share Transactions:

Each Fund is authorized to issue 200 million shares (MVF is authorized to
issue an unlimited number 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
without approval of Common Shareholders.

Common Shares

Shares issued and outstanding for MZA for the years ended July 31, 2010
and July 31, 2009 increased by 8,600 and 7,393, respectively, as a result
of dividend reinvestment.

Shares issued and outstanding remained constant for MNE, MYC, MYF and
MYJ for the years ended July 31, 2010 and July 31, 2009.

Preferred Shares

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

From time to time in the future, each Fund may effect repurchases of its
Preferred Shares at prices below their liquidation preference as agreed
upon by the Fund and seller. Each Fund also may redeem its Preferred
Shares from time to time as provided in the applicable Governing
Instrument. Each Fund intends to effect such redemptions and/or repur-
chases 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 holders of
Common Shares (one vote per share) as a single class. However, the hold-
ers 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

Notes to Financial Statements (continued)

a Funds' 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, 2010:

 

¹ 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 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% 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.

Dividends on seven-day and 28-day Preferred Shares are cumulative at a
rate which is reset every seven or 28 days, respectively, based on the
results of an auction. If the Preferred Shares fail to clear the auction on an
auction date, each 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 maxi-
mum applicable rate on the Preferred Shares is as footnoted in the pre-
ceding table above. The low, high and average dividend rates on the
Preferred Shares for each Fund for the year ended July 31, 2010 were
as follows:

 

Since February 13, 2008, the Preferred Shares of the Funds 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 0.24% to 1.63%
for the year ended July 31, 2010. 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 the Funds'
Preferred Shares may not occur for some time, if ever, and even if liquidity
does resume, holders of the Preferred Shares 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 declara-
tion, distribution or purchase, asset coverage with respect to the outstand-
ing Preferred Shares is less than 200%.

The Funds pay commissions of 0.25% on the aggregate principal amount
of all shares that successfully clear their auctions and 0.15% on the
aggregate principal amount of all shares that fail to clear their auctions.
Certain broker dealers have individually agreed to reduce commissions
for failed auctions.

During the year ended July 31, 2009, certain funds announced the follow-
ing redemptions of Preferred Shares at a price of $25,000 per share plus
any accrued and unpaid dividends through the redemption date:

 

The Funds financed the Preferred Share redemptions with cash received
from TOB transactions.

Preferred Shares issued and outstanding remained constant for the year
ended July 31, 2010 for all Funds and for the year ended July 31, 2009
for MNE.

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, 2010, and the related
statement of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended,
and the financial highlights for each of the two years in the period 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 statement of assets and liabilities, including the schedule
of investments, of BlackRock MuniYield Arizona Fund, Inc. as of July 31,
2010, and the related statement of operations for the year then ended,
the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the two years
in the period then ended, the period November 1, 2007 to July 31, 2008
and for each of the three years in the period ended October 31, 2007.
We have also audited the accompanying statements of assets and liabili-
ties, including the schedules of investments, of BlackRock MuniYield
California Fund, Inc. and BlackRock MuniYield Investment Fund as of July
31, 2010, and the related statements of operations and cash flows for
the year then ended, the statements of changes in net assets for each of
the two years in the period then ended, and the financial highlights for
each of the two years in the period then ended, the period November 1,
2007 to July 31, 2008 and for each of the three years in the period
ended October 31, 2007. We have also audited the accompanying state-
ment of assets and liabilities, including the schedule of investments, of
BlackRock MuniYield New Jersey Fund, Inc. as of July 31, 2010, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended,
and the financial highlights for each of the two years in the period then
ended, the period December 1, 2007 to July 31, 2008 and for each of
the three years in the period ended November 30, 2007. These financial
statements and financial highlights are the responsibility of the Funds’
management. Our responsibility is to express an opinion on these finan-
cial statements and financial highlights based on our audits. The financial
highlights for 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, 2010, 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,
2010, the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended, and the
financial highlights for each of the two years in the period 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 gen-
erally accepted in the United States of America. Additionally, in our opin-
ion, the financial statements and financial highlights referred to above
present fairly, in all material respects, the financial position of BlackRock
MuniYield Arizona Fund, Inc. as of July 31, 2010, the results of its opera-
tions for the year then ended, the changes in its net assets for each of the
two years in the period then ended, and the financial highlights for each
of the two years in the period then ended, the period November 1, 2007
to July 31, 2008 and for each of the three years in the period ended
October 31, 2007, 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 California Fund, Inc. and of BlackRock MuniYield Investment
Fund as of July 31, 2010, the results of their operations and their cash
flows for the year then ended, the changes in their net assets for each of
the two years in the period then ended, and the financial highlights for
each of the two years in the period then ended,the period November 1,
2007 to July 31, 2008 and for each of the three years in the period
ended October 31, 2007, in conformity with accounting principles gen-
erally accepted in the United States of America. Additionally, in our opin-
ion, the financial statements and financial highlights referred to above
present fairly, in all material respects, the financial position of BlackRock
MuniYield New Jersey Fund, Inc. as of July 31, 2010, the results of its
operations for the year then ended, the changes in its net assets for each
of the two years in the period then ended, and the financial highlights for
each of the two years in the period then ended, the period December 1,
2007 to July 31, 2008 and for each of the three years in the period

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements

The Board of Directors and the Board of Trustees, as the case may be
(each, a “Board,” and, collectively, the "Boards," and 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 8, 2010 and
May 13-14, 2010 to consider the approval of each Fund’s investment
advisory agreement (each, an “Advisory Agreement”) with BlackRock
Advisors, LLC (the “Manager”), each Fund’s investment advisor. Each
Board also considered the approval of the sub-advisory agreement
(each, a “Sub-Advisory Agreement”) between the Manager and BlackRock
Investment Management, LLC (the “Sub-Advisor”) with respect to its Fund.
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.”

Activities and Composition of the Board

The Board of each Fund consists of ten individuals, eight of whom are not
“interested persons” of such Fund as defined in the Investment Company
Act of 1940 (the “1940 Act”) (the “Independent Board Members”). The
Board Members are responsible for the oversight of the operations of each
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 the Boards is an Independent Board Member. The
Boards have 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 also has one interested Board Member) and
is chaired by an Independent Board Member. The Boards also have two
ad hoc committees, the Joint Product Pricing Committee, which consists
of Independent Board Members and the directors/trustees of the boards
of certain other BlackRock-managed funds, who are not “interested per-
sons” of their respective funds, and the Ad Hoc Committee on Auction
Market Preferred Shares.

The Agreements

Pursuant to the 1940 Act, the Boards are required to consider the cont-
inuation of the Agreements on an annual basis. In connection with this
process, the Boards assessed, among other things, the nature, scope
and quality of the services provided to the Funds by the personnel of
BlackRock and its affiliates, including investment management, admin-
istrative and shareholder services, oversight of fund accounting and
custody, marketing services and assistance in meeting applicable legal
and regulatory requirements.

From time to time throughout the year, each Board, acting directly and
through its committees, considered at each of its meetings factors that
are relevant to its annual consideration of the renewal of the Agreements,
including the services and support provided by BlackRock to the respective
Fund and its shareholders. Among the matters the Board considered were:

(a) investment performance for one-, three- and five-year periods, as app-
licable, against peer funds, and applicable benchmarks, if any, as well as
senior management's and portfolio managers’ analysis of the reasons for
any over performance or underperformance against a Fund’s peers and/or
benchmark, as applicable; (b) fees, including advisory, and other amounts
paid to BlackRock and its affiliates by each Fund for services such as
call center and fund accounting; (c) each Fund’s operating expenses;
(d) the resources devoted to and compliance reports relating to each
Fund’s investment objective, policies and restrictions; (e) each Fund’s
compliance with its Code of Ethics and compliance policies and proce-
dures; (f) the nature, cost and character of non-investment management
services provided 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 each Fund’s
valuation and liquidity procedures; (k) an analysis of contractual and
actual management fees for products with similar investment objectives
across the open-end fund, closed-end fund and institutional account
product channels, as applicable; and (l) periodic updates on
BlackRock’s business.

Board Considerations in Approving the Agreements

The Approval Process: Prior to the April 8, 2010 meeting, the Boards
requested and received materials specifically relating to the Agreements.
The Boards are engaged in a process with BlackRock to periodically 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 perform-
ance of each Fund as compared with a peer group of funds as determined
by Lipper and a customized peer group selected by BlackRock, as app-
licable (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 clients and open-end funds,
under similar investment mandates; (d) the impact of economies of scale;

(e) a summary of aggregate amounts paid by each Fund to BlackRock and
(f) if applicable, a comparison of management fees to similar BlackRock

closed-end funds, as classified by Lipper.

At an in-person meeting held on April 8, 2010, the Boards reviewed
materials relating to their consideration of the Agreements. As a result of
the discussions that occurred during the April 8, 2010 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 13 – 14, 2010 Board meeting.

At an in-person meeting held on May 13 – 14, 2010, each Fund’s Board,
including the Independent Board Members, unanimously approved the
continuation of the Advisory Agreement between the Manager and each
respective Fund and the Sub-Advisory Agreement between the Manager
and the Sub-Advisor with respect to each Fund, each for a one-year term
ending June 30, 2011. In approving the continuation of the Agreements,

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

the Boards considered: (a) the nature, extent and quality of the services
provided by BlackRock; (b) the investment performance of each Fund and
BlackRock; (c) the advisory fee and the cost of the services and profits to
be realized by BlackRock and its affiliates from their relationship with each
Fund; (d) economies of scale; and (e) other factors deemed relevant by
the Board Members.

The Boards also considered other matters they deemed important to the
approval process, such as services related to the valuation and pricing of
each Fund’s portfolio holdings, direct and indirect benefits to BlackRock
and its affiliates and significant shareholders from their relationship with
each Fund and advice from independent legal counsel with respect to the
review process and materials submitted for the Boards’ review. The Boards
noted the willingness 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 Provided by BlackRock:
The Boards, including the Independent Board Members, reviewed the
nature, extent and quality of services provided by BlackRock, including
the investment advisory services and the resulting performance of each
Fund. Throughout the year, the Boards compared each Fund’s performance
to the performance of a comparable group of closed-end funds, and
the performance of a relevant benchmark, if any. The Boards met with
BlackRock’s senior management personnel responsible for investment
operations, including the senior investment officers. The Boards also
reviewed the materials provided by each Fund’s portfolio management
team discussing each Fund’s performance and each Fund’s investment
objective, strategies and outlook.

The Boards considered, among other factors, the number, education
and experience of BlackRock’s investment personnel generally and each
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,
BlackRock’s credit analysis capabilities, BlackRock’s risk analysis capabili-
ties and BlackRock’s approach to training and retaining portfolio managers
and other research, advisory and management personnel. The Boards also
reviewed a general description of BlackRock’s compensation structure with
respect to each Fund’s portfolio management team and BlackRock’s ability
to attract and retain high-quality talent.

In addition to advisory services, the Boards considered the quality of the
administrative and non-investment advisory services provided to each
Fund. BlackRock and its affiliates and significant shareholders provide
each Fund with certain administrative and other services (in addition to
any such services provided to each Fund by third parties) and officers and
other personnel as are necessary for the operations of each Fund. In addi-
tion to investment advisory services, BlackRock and its affiliates provide
each Fund with other services, including (i) preparing disclosure docu-
ments, such as the prospectus and the statement of additional information
in connection with the initial public offering and periodic shareholder
reports; (ii) preparing communications with analysts to support secondary
market trading of each Fund; (iii) assisting with daily accounting and pric-

ing; (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) providing legal and compliance support; and
(viii) performing other administrative functions necessary for the operation
of each Fund, such as tax reporting, fulfilling regulatory filing requirements,
and call center services. The Boards reviewed the structure and duties of
BlackRock’s fund administration, accounting, legal and compliance depart-
ments and considered BlackRock’s policies and procedures for assuring
compliance with applicable laws and regulations.

B. The Investment Performance of the Funds and BlackRock: The Boards,
including the Independent Board Members, also reviewed and considered
the performance history of each Fund. In preparation for the April 8, 2010
meeting, the Boards were provided with reports, independently prepared by
Lipper, which included a comprehensive analysis of each Fund’s perform-
ance. The Boards also reviewed a narrative and statistical analysis of the
Lipper data that was prepared by BlackRock, which analyzed various fac-
tors that affect Lipper’s rankings. In connection with their review, the Boards
received and reviewed information regarding the investment performance
of each Fund as compared to a representative group of similar funds as
determined by Lipper and to all funds in each Fund’s applicable Lipper
category, and in the case of MZA, MYC and MYF, a customized peer group
selected by BlackRock. The Boards were provided with a description of the
methodology used by Lipper to select peer funds. The Boards regularly
review the performance of each Fund throughout the year.

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
Customized Lipper Peer Group Composite in each of the one-, three-
and five-year periods reported.

The Board of MNE noted that MNE performed below the median of its
Lipper Performance Composite in the three- and five-year periods reported,
but that MNE performed better than or equal to the median of its Lipper
Performance Composite in the one-year period reported. The Board of MNE
and BlackRock reviewed the reasons for MNE’s underperformance during
the three- and five-year periods compared with its Peers. The Board of
MNE was informed that, among other things, MNE’s portfolio managers
positioned the portfolio toward the longer end of the duration range. This
positioning leaves MNE more exposed to swings in interest rates, which
had a negative impact on MNE’s performance toward the end of 2007
and throughout 2008.

The Board of MYC noted that MYC performed below the median of its
Customized Lipper Peer Group Composite in the one- and five-year periods
reported, but that MYC performed better than or equal to the median of
its Customized Lipper Peer Group Composite in the three-year period
reported. The Board of MYC and BlackRock reviewed the reasons for MYC’s
underperformance during the one- and five-year periods compared with its
Peers. The Board of MYC was informed that, among other things, underper-
formance mainly stems from a below market dividend distribution rate.
In addition, the prospectus prohibits investments in non investment grade
securities, which detracts from MYC’s ability to generate a higher
income accrual.

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

The Board of MYJ noted that MYJ performed below the median of its Lipper
Performance Composite in the one- and three-year periods reported, but
that MYJ performed better than or equal to the median of its Lipper
Performance Composite in the five-year period reported. The Board of MYJ
and BlackRock reviewed the reasons for MYJ’s underperformance during
the one- and three-year periods compared with its Peers. The Board of MYJ
was informed that, among other things, an overweight to the hospital sector
hindered performance.

The Boards of MNE, MYC and MYJ and BlackRock discussed BlackRock’s
strategy for improving each respective Fund’s performance and BlackRock’s
commitment to providing the resources necessary to assist each Fund’s
portfolio managers and to improve each Fund’s performance.

The Board of MYF noted that MYF performed below the median of its
Customized Lipper Peer Group Composite in each of the one-, three- and
five-year periods reported. The Board of MYF and BlackRock reviewed the
reasons for MYF’s underperformance during these periods compared with
its Peers. The Board of MYF was informed that, among other things, while
MYF’s portfolio managers have reduced MYF’s Florida exposure, MYF
remains over-weighted in Florida holdings versus its Peers, which has
hindered MYF’s performance, as the state of Florida continues to have
budget deficit concerns and a very weak housing market.

The Board of MYF and BlackRock discussed BlackRock’s strategy for
improving MYF’s performance and BlackRock’s commitment to providing
the resources necessary to assist MYF’s portfolio managers and to improve
MYF’s performance, in part through the repositioning of MYF’s portfolio.

The Boards noted that BlackRock has made changes to the organization
of the overall fixed income group management structure designed to result
in a strengthened leadership team with clearer accountability.

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: The Boards, including the Independent Board
Members, reviewed each Fund’s contractual advisory fee rate compared
with the other funds in its Lipper category. The Boards also compared each
Fund’s total expenses, as well as actual management fees, to those of
other funds in its Lipper category. The Boards considered the services
provided and the fees charged by BlackRock to other types of clients
with similar investment mandates, including separately managed
institutional accounts.

The Boards received and reviewed statements relating to BlackRock’s
financial condition and profitability with respect to the services it provided
each Fund. The Boards were also provided with a profitability analysis that
detailed the revenues earned and the expenses incurred by BlackRock for
services provided to each Fund. The Boards reviewed BlackRock’s prof-
itability with respect to each Fund and other funds the Boards currently
oversee for the year ended December 31, 2009 compared to available
aggregate profitability data provided for the year ended December 31,
2008. 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 allo-
cating costs among various advisory products. The Boards recognized that
profitability may be affected by numerous factors including, among other
things, fee waivers and expense reimbursements by the Manager, the types
of funds managed, expense allocations and business mix, and the difficulty
of comparing profitability as a result of those factors.

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 was available, the Boards considered BlackRock’s overall
operating margin, in general, compared to the operating margin for leading
investment management firms whose operations include advising closed-
end funds, among other product types. That data indicates that operating
margins for BlackRock with respect to its registered funds are generally
consistent with margins earned by similarly situated publicly traded com-
petitors. In addition, the Boards considered, among other things, certain
third party data comparing BlackRock’s operating margin with that of
other publicly-traded asset management firms. That third party data
indicates 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
each Fund by BlackRock, and BlackRock’s and its affiliates’ profits relating
to the management and distribution of each Fund 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 each Fund. 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.

The Board of each Fund noted that its Fund’s contractual management
fee rate was lower than or equal to the median contractual management
fee rate paid by the Fund’s Peers, in each case, before taking into account
any expense reimbursements or fee waivers.

D. Economies of Scale: The Boards, including the Independent Board
Members, considered the extent to which economies of scale might be
realized as the assets of each Fund increase. The Boards also considered
the extent to which each Fund benefits from such economies and whether
there should be changes in the advisory fee rate or structure in order to
enable each Fund to participate in these economies of scale, for example
through the use of breakpoints in the advisory fee based upon the asset
level of each Fund.

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 with total closed-end
fund nets assets exceeding $10 billion, as of December 31, 2009, used
a complex level breakpoint structure.

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

E. Other Factors Deemed Relevant by the Board Members: The Boards,
including the Independent Board Members, also took into account other
ancillary or “fall-out” benefits that BlackRock or its affiliates and significant
shareholders may derive from their respective relationships with the Funds,
both tangible and intangible, such as BlackRock’s ability to leverage its
investment professionals who manage other portfolios, an increase in
BlackRock’s profile in the investment advisory community, and the engage-
ment of BlackRock’s affiliates and significant shareholders as service
providers to each Fund, including for administrative and distribution serv-
ices. 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 also noted that BlackRock may use and benefit from third party
research obtained by soft dollars generated by certain mutual fund trans-
actions to assist in managing all or a number of its other client accounts.
The Boards further noted that BlackRock completed the acquisition of a
complex of exchange-traded funds (“ETFs”) on December 1, 2009, and
that BlackRock’s funds may invest in such ETFs without any offset against
the management fees payable by the funds to BlackRock.

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

The Boards noted the competitive nature of the closed-end fund market-
place, and that shareholders are able to sell their respective Fund’s shares
in the secondary market if they believe that the Fund’s fees and expenses
are too high or if they are dissatisfied with the performance of the Fund.

Conclusion

The Boards, including the Independent Board Members, unanimously
approved the continuation of the Advisory Agreement between the Manager
and each Fund for a one-year term ending June 30, 2011 and the Sub-
Advisory Agreement between the Manager and the Sub-Advisor with
respect to each Fund for a one-year term ending June 30, 2011. As part
of its approval, each Board considered the discussions of BlackRock’s fee
structure, as it applies to its respective Fund, being conducted by the ad
hoc Joint Product Pricing Committee. Based upon its evaluation of all
of the aforementioned factors in their totality, the Boards, including the
Independent Board Members, were satisfied that the terms of the Agree-
ments were fair and reasonable and in the best interest of each Fund and
its shareholders. In arriving at a decision to approve the Agreements, the
Boards 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 reflect the results of several years of review
by the 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.

Automatic Dividend Reinvestment Plan

Pursuant to each Fund’s Dividend Reinvestment Plan (the “Plan”), common
shareholders are automatically enrolled to have all distributions of divi-
dends and capital gains reinvested by BNY Mellon Shareowner Services
for MZA, MYC, MYF and MYJ and Computershare Trust Company, N.A. for
MNE (individually, the “Plan Agent” or together, the “Plan Agents”) in the
respective Fund’s shares pursuant to the Plan. Shareholders who do not
participate in the Plan will receive all distributions in cash paid by check
and mailed directly to the shareholders of record (or if the shares are held
in street or other nominee name, then to the nominee) by the Plan Agent,
which serves as agent for the shareholders in administering the Plan.

After the Funds declare a dividend or determine to make a capital gain dis-
tribution, the Plan Agent will acquire shares for the participants’ accounts,
depending upon the following circumstances, either (i) through receipt of
unissued but authorized shares from the Fund (“newly issued shares”) or
(ii) by purchase of outstanding shares on the open market or on the Fund’s
primary exchange (“open-market purchases”). If, on the dividend payment
date, the net asset value per share (“NAV”) is equal to or less than the
market price per share plus estimated brokerage commissions (such condi-
tion often referred to as a “market premium”), the Plan Agent will invest the
dividend amount in newly issued shares on behalf of the participants. The
number of newly issued shares to be credited to each participant’s account
will be determined by dividing the dollar amount of the dividend by the
NAV on the date the shares are issued. However, if the NAV is less than
95% of the market price on the payment date, the dollar amount of the
dividend will be divided by 95% of the market price on the payment date.
If, on the dividend payment date, the NAV is greater than the market value
per share plus estimated brokerage commissions (such condition often
referred to as a “market discount”), the Plan Agent will invest the dividend
amount in shares acquired on behalf of the participants in open-market
purchases. 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 pre-
mium during the purchase period, the Plan Agents will invest any un-
invested portion in newly issued shares.

Participation in the Plan is completely voluntary and may be terminated or
resumed at any time without penalty by notice if received and processed
by the Plan Administrator prior to the dividend record date; otherwise such
termination or resumption will be effective with respect to any subsequently
declared dividend or other distribution.

The Plan Agent’s fees for the handling of the reinvestment of dividends and
distributions will be paid by each Fund. However, each participant will pay
a pro rata share of brokerage commissions incurred with respect to the
Plan Agent’s open market purchases in connection with the reinvestment of
dividends and distributions. The automatic reinvestment of dividends and
distributions will not relieve participants of any federal income tax that may
be payable on such dividends or distributions.

Each Fund reserves the right to amend or terminate the Plan. There is
no direct service charge to participants in the Plan; however, each Fund
reserves the right to amend the Plan to include a service charge payable
by the participants. Participants that request a sale of shares through
Computershare Trust Company, N.A. are subject to a $2.50 sales fee and
a $0.15 per share sold brokerage commission. Participants that request
a sale of shares through BNY Mellon Shareowner Services are subject to a
$0.02 per share sold brokerage commission. All correspondence concern-
ing the Plan should be directed to the respective Plan Agent: BNY Mellon
Shareowner Services, P.0. Box 358035, Pittsburgh, PA 15252-8035,
Telephone: (866) 216-0242 for shareholders of MZA, MYC, MYF and MYJ
or Computershare Trust Company, N.A., P.O. Box 43078, Providence, RI
02940-3078, Telephone: (800) 699-1BFM or overnight correspondence
should be directed to the Plan Agent at 250 Royall Street, Canton, MA
02021 for shareholders of MNE.

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

This report is transmitted to shareholders only. It is not a prospectus. Past performance results shown in this report should not be

considered a representation 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 auc-

tions, may reduce the Common Shares’ yield. 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 (retired effective December 31, 2009)
Frank J. Fabozzi
James T. Flynn
W. Carl Kester
Karen P. Robards

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.

1 The nature of the services include assurance and related services reasonably related to the performance of the audit of
financial statements not included in Audit Fees.
2 The nature of the services include tax compliance, tax advice and tax planning.
3 The nature of the services include a review of compliance procedures and attestation thereto.

(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 per project. 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 the Committee Chairman 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:

(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.

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 at
http://www.sec.gov .

Item 8 – Portfolio Managers of Closed-End Management Investment Companies – as of July 31,
2010.

(a)(1) The registrant is managed by a team of investment professionals comprised of
Theodore R. Jaeckel, Jr., CFA, Managing Director at BlackRock, Inc. and Walter
O’Connor, Managing Director at BlackRock, Inc. Each is a member of BlackRock,
Inc.’s municipal tax-exempt management group. Each is jointly responsible for the
day-to-day management of the registrant’s portfolio, which includes setting the
registrant’s overall investment strategy, overseeing the management of the registrant
and/or selection of its investments. Messrs. Jaeckel and O’Connor have been
members of the registrant’s portfolio management team since 2006 and 1992,
respectively.

 

(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.

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 and Restricted Stock
Program.

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 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”) — From time to time long-
term incentive equity awards are granted to certain key employees to aid in retention, align
their interests with long-term shareholder interests and motivate performance. Equity
awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once
vested, settle in BlackRock, Inc. common stock. Messrs. Jaeckel and O’Connor 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. Jaeckel and O’Connor 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.
