2 SEMI-ANNUAL REPORT FEBRUARY 28, 2010

Dear Shareholder

The past year marked a pivotal turning point for global markets as the Great Recession that started in December 2007 began to recede and give way to recovery. The dramatic about-face could be attributed to a confluence of factors, most notably the extraordinary policy actions of global governments and central banks, a resurgence in corporate profits and growing signs of stability and healing in world economies.

After reaching a trough in early March 2009, stocks galloped higher as investors were lured back into the markets by depressed valuations, desire for higher yields and increasing confidence that all-out financial disaster had been averted. The result was a powerful upswing in global equities and other higher-risk assets through the end of 2009. More recently, the combination of mixed economic data, lingering deflation issues (especially in Europe) and proposed fees and levies on banks dampened investor conviction, resulting in a several-week bout of profit-taking. The selloff had a more pronounced negative effect on international and emerging market equities due primarily to concerns of higher interest rates in Asia and negative headlines out of Europe, particularly in Greece.

Generally speaking, investors’ renewed affinity for risk was notable in the fixed income markets as well, where non-Treasury assets made a robust recovery. One of the major themes in 2009 was the reversal of the flight-to-quality trade. High yield, one of the most battered areas during the financial crisis, emerged as the strongest-performing fixed income sector in both the taxable and tax-exempt space. Despite weak fundamentals, the municipal market produced solid returns as technical conditions remained supportive of the asset class. Municipal bond mutual funds enjoyed strong inflows and tax-exempt issuance remained low thanks to the ever-increasing popularity of the Build America Bond program. Nevertheless, state and local fiscal woes and bankruptcy fears remain firmly in the spotlight, and bear close monitoring.

At the same time, yields on money market securities declined throughout the reporting period and remain near all-time lows, with the Federal Open Market Committee reiterating that economic circumstances are likely to necessitate an accommodative interest rate stance for an “extended period.” Investor assets in money market funds declined from the peak registered in early 2009, but remain above levels registered prior to the financial crisis that began in 2007.

Against this backdrop, the major market averages posted the following returns:

Total Returns as of February 28, 2010	6-month		12-month
US equities (S&P 500 Index)	9.32	%	53.62	%
Small cap US equities (Russell 2000 Index)	10.59		63.95
International equities (MSCI Europe, Australasia, Far East Index)	0.72		54.58
3-month Treasury bill (BofA Merrill Lynch 3-Month Treasury Bill Index)	0.07		0.20
US Treasury securities (BofA Merrill Lynch 10-Year US Treasury Index)	0.07		(1.54	)
Taxable fixed income (Barclays Capital US Aggregate Bond Index)	3.19		9.32
Tax-exempt fixed income (Barclays Capital Municipal Bond Index)	4.13		9.98
High yield bonds (Barclays Capital US Corporate High Yield 2% Issuer Capped Index)	13.86		55.20

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

The market continues to show signs of improvement, but questions about the strength and sustainability of the recovery abound.

Trust Summary as of February 28, 2010 BlackRock Core Bond Trust

Investment Objective

BlackRock Core Bond Trust (BHK) (the “Trust”) seeks to provide high current income with the potential for capital appreciation.

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

Performance

For the six months ended February 28, 2010, the Trust returned 6.72% based on market price and 8.73% based on net asset value (“NAV”). For the same period, the closed-end Lipper Corporate Debt Funds BBB-Rated category posted an average return of 9.51% on a market price basis and 8.82% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The Trust’s longer duration relative to its peers detracted from performance as rates rose during the period. On the positive side, the Trust benefited from its overweight in high yield corporates, which outperformed investment-grade credit as risk assets rebounded sharply over the six months. An out-of-index allocation to securitized sectors, including commercial mortgage-backed securities, non-agency mortgage-backed securities (“MBS”), asset-backed securities and agency MBS, aided performance as well.

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 views are not intended to be a forecast of future events and are no guarantee of future results.

Trust Summary as of February 28, 2010 BlackRock Corporate High Yield Fund V, Inc.

Investment Objective

BlackRock Corporate High Yield Fund V, Inc. (HYV) (the “Trust”) seeks to provide shareholders with current income by investing primarily in a diversified portfolio of fixed income securities that are rated in the lower rating categories of the established rating services (Ba or lower by Moody’s or BB or lower by S&P’s) or are unrated securities of comparable quality.

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

Performance

For the six months ended February 28, 2010, the Trust returned 21.19% based on market price and 21.73% based on NAV. For the same period, the closed-end Lipper High Current Yield Funds (Leveraged) category posted an average return of 21.84% on a market price basis and 18.08% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. During the period, we found particularly good value in the automotive segment, which represented the Trust’s largest sector overweight. As a group, automotive holdings performed quite well and, thus, were key contributors to performance. In addition, investments in select special situations or distressed credits (including several in the automotive sector) enhanced results. On a credit basis, the Trust’s underweight position in BB credits and overweight in the lower-quality ratings and nonrated credits were additive. On the other hand, the Trust maintained relatively low levels of leverage (at period end, 23% of the Trust’s total managed assets), which detracted from performance versus the Lipper competitors, who maintained leverage closer to the 33⅓% regulatory limit. The Trust also held a roughly 14% position in floating rate loan interests. On balance, the position hindered performance as the sector underperformed high yield during the period, but security selection was favorable.

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

Performance

For the six months ended February 28, 2010, the Trust returned 11.31% based on market price and 18.78% based on NAV. For the same period, the closed-end Lipper High Current Yield Funds (Leveraged) category posted an average return of 21.84% on a market price basis and 18.08% on a NAV basis.

During the period, we found particularly good value in the automotive segment, which represented the Trust’s largest sector overweight. As a group, automotive holdings performed quite well and, thus, were key contributors to performance.

The Trust also held a roughly 12% position in floating rate loan interests. On balance, the position hindered performance as the sector underperformed high yield during the period, but security selection was favorable. The Trust’s cash position was about 6% at period end. Cash positions negatively affected the Trust during a period of high returns for the high yield market.

8 SEMI-ANNUAL REPORT FEBRUARY 28, 2010

Trust Summary as of February 28, 2010 BlackRock Income Opportunity Trust, Inc.

Investment Objective

BlackRock Income Opportunity Trust, Inc. (BNA) (the “Trust”) seeks to provide current income and capital appreciation in a portfolio of primarily U.S. dollar-denominated securities.

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

Performance

For the six months ended February 28, 2010, the Trust returned 4.61% based on market price and 6.52% based on NAV. For the same period, the closed-end Lipper Corporate Debt Funds BBB-Rated category posted an average return of 9.51% on a market price basis and 8.82% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The Trust’s underweight in high yield corporates hindered performance during the period, as these securities outperformed investment-grade credit amid a sharp rebound in risk assets. The Trust’s longer duration relative to its peers also detracted from results as rates rose. On the positive side, the Trust benefited from an out-of-index allocation to securitized sectors, including commercial mortgage-backed securities, non-agency MBS, asset-backed securities and agency MBS. In addition, the Trust benefited from its curve positioning as the curve steepened over the six months.

SEMI-ANNUAL REPORT FEBRUARY 28, 2010 9

Trust Summary as of February 28, 2010 BlackRock Income Trust, Inc.

Investment Objective

BlackRock Income Trust, Inc. (BKT) (the “Trust”) seeks to provide high monthly income while preserving capital by investing in a portfolio of mortgage-backed securities.

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

Performance

For the six months ended February 28, 2010, the Trust returned 2.26% based on market price and 5.42% based on NAV. For the same period, the closed-end Lipper US Mortgage Funds category posted an average return of 14.10% on a market price basis and 9.15% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The Trust’s underweight in agency MBS, in favor of US Treasuries and agency debt, detracted from performance as spread sectors continued to rally during the second half of 2009. On the positive side, the Trust benefited from out-of-index allocations to non-agency MBS and commercial MBS, which outperformed agency MBS for the period as risk assets continued to rally due to continued government support and improving economic indicators. In addition, the Trust benefited from security selection focusing on current coupon MBS, which rallied due to the Federal Reserve’s reduction in supply through the agency MBS purchase program. The Trust’s cash position (45% at period end) serves primarily to back our forward positions held in mortgage TBA (“To Be Announced”) contracts and, therefore, did not have a material impact on performance.

Trust Summary as of February 28, 2010 BlackRock Strategic Bond Trust

Investment Objective

BlackRock Strategic Bond Trust (BHD) (the “Trust”) seeks total return through high current income and capital appreciation.

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

Performance

For the six months ended February 28, 2010, the Trust returned 11.96% based on market price and 12.44% based on NAV. For the same period, the closed-end Lipper High Current Yield Funds (Leveraged) posted an average return of 21.84% on a market price basis and 18.08% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. Positioning in the high yield portion of the portfolio was a plus during the period. We found particularly good value in the automotive segment, which represented the Trust’s largest sector overweight. As a group, automotive holdings performed quite well and, thus, were key contributors to performance. In addition, investments in select special situations or distressed credits (including several in the automotive sector) enhanced results. On a credit basis, the Trust’s underweight position in BB credits and overweight in the lower-quality ratings and nonrated credits were additive. A lower allocation to corporates, in favor of bank loans, was advantageous as well. On the other hand, the Trust’s allocation to investment-grade credit detracted from relative performance during a period in which high yield outperformed. (Most of the funds in the Lipper category invest primarily in high yield.) The Trust’s relatively low levels of leverage (at period end, 6% of the Trust’s total managed assets) also detracted.

The Benefits and Risks of Leveraging

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

The Trusts may utilize leverage through borrowings, including participation in the Term Asset-Backed Securities Loan Facility (“TALF”), or through entering into reverse repurchase agreements and dollar rolls. In general, the concept of leveraging is based on the premise that the cost of assets to be obtained from leverage will be based on short-term interest rates, which normally will be lower than the income earned by each Trust on its longer-term portfolio investments. To the extent that the total assets of each Trust (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, each Trust’s shareholders will benefit from the incremental net income.

The interest earned on securities purchased with the proceeds from leverage is paid to shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the per share NAV. However, in order to benefit shareholders, the yield curve must be positively sloped; that is, short-term interest rates must be lower than long-term interest rates. If the yield curve becomes negatively sloped, meaning short-term interest rates exceed long-term interest rates, income to shareholders will be lower than if the Trusts had not used leverage.

To illustrate these concepts, assume a Trust’s capitalization is $100 million and it borrows an additional $30 million, creating a total value of $130 million available for investment in long-term securities. If prevailing short-term interest rates are 3% and long-term interest rates are 6%, the yield curve has a strong positive slope. In this case, the Trust pays borrowing costs and interest expense on the $30 million of borrowings based on the lower short-term interest rates. At the same time, the securities purchased by the Trust with assets received from the borrowings earn the income based on long-term interest rates. In this case, the borrowing costs and interest expense is significantly lower than the income earned on the Trust’s long-term investments, and therefore each Trust’s shareholders is 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 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 Trust pays interest expense on the higher short-term interest rates whereas the Trust’s total portfolio earns income based on lower long-term interest rates.

Furthermore, the value of the Trust’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 redemption value of the Trust’s borrowings do not fluctuate in relation to interest rates. As a result, changes in interest rates can influence the Trust’s NAV positively or negatively in addition to the impact on Trust performance from leverage from borrowings.

The use of leverage may enhance opportunities for increased income to the Trusts and shareholders, but as described above, it also creates risks as short- or long-term interest rates fluctuate. Leverage also will generally cause greater changes to each Trust’s 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, each Trust’s 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, each Trust’s net income will be less than if leverage had not been used, and therefore the amount available for distribution to shareholders will be reduced. Each Trust may be required to sell portfolio securities at inopportune times or at distressed 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 Trust to incur losses. The use of leverage may limit each Trust’s ability to invest in certain types of securities or use certain types of hedging strategies. Each Trust will incur expenses in connection with the use of leverage, all of which are borne by Common Shareholders of each Trust and may reduce income to the Common Shares.

Under the Investment Company Act of 1940, the Trusts are permitted to borrow through a credit facility up to 33⅓% of their total managed assets. As of February 28, 2010, the Trusts had outstanding leverage from borrowings and/or reverse repurchase agreements as a percentage of their total managed assets as follows:

	Percent of Leverage
BHK	31	%
HYV	23	%
HYT	21	%
HIS	18	%
BHY	18	%
BNA	28	%
BKT	2	%
BHD	6	%

Derivative Financial Instruments

The Trusts may invest in various derivative instruments, including financial futures contracts, swaps, options and foreign currency exchange contracts, as specified in Note 2 of the Notes to Financial Statements, which constitute forms of economic leverage. Such instruments are used to obtain exposure to a market without owning or taking physical custody of securities or to hedge market, equity, credit, foreign currency exchange rate 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 other party to the transaction or illiquidity of the derivative instrument. Each Trust’s ability to successfully use a derivative instrument depends on the investment advisor’s ability to accurately predict 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 Trust to sell or purchase portfolio securities at inopportune times or distressed values, may limit the amount of appreciation a Trust can realize on an investment or may cause a Trust to hold a security that they might otherwise sell. The Trusts’ investments in these instruments are discussed in detail in the Notes to Financial Statements.

•	For Trust compliance purposes, the Trust’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Trust management. This definition may not apply for purposes of this report, which may combine industry sub-classifications for reporting ease.
•	Fair Value Measurements — Various inputs are used in determining the fair value of investments, which are as follows:
	•	Level 1 — price quotations in active markets/exchanges for identical assets and liabilities
	•	Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, repayment 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 Trust’s own assumptions used in determining the fair value of investments)
	The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Trust’s policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

1	Using Standard & Poor’s ratings of the issuer.
2	Using maximum potential amount the Trust may be required to pay should a negative credit event take place as defined under the terms of the agreement.

•	For Trust compliance purposes, the Trust’s industry classifications refer to any one or more of the industry sub-classifications used by one more widely recognized market indexes or ratings group indexes, and/or as defined by Trust management. This definition may not apply for purposes of this report which may combine industry sub-classifications for reporting ease.
•	Fair Value Measurements — Various inputs are used in determining the fair value of investments, which are as follows:
	•	Level 1 — price quotations in active markets/exchanges for identical assets and liabilities
	•	Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, repayment 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 Trust’s own assumptions used in determining the fair value of investments)
	The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Trust’s policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

Schedule of Investments (concluded) BlackRock Income Opportunity Trust, Inc. (BNA)

• Fair Value Measurements — Various inputs are used in determining the fair value of investments, which are as follows:

• Level 1 — price quotations in active markets/exchanges for identical assets and liabilities

• Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, repayment 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 Trust’s own assumptions used in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

•	Fair Value Measurements — Various inputs are used in determining the fair value of investments, which are as follows:
	•	Level 1 — price quotations in active markets/exchanges for identical assets and liabilities
	•	Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, repayment 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 Trust’s own assumptions used in determining the fair value of investments) The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Trust’s policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

•	For Trust compliance purposes, the Trust’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by Trust management. This definition may not apply for purposes of this report, which may combine such industry sub-classifications for reporting ease.
•	Fair Value Measurements — Various inputs are used in determining the fair value of investments, which are as follows:
	•	Level 1 — price quotations inactive markets/exchanges for identical assets and liabilities
	•	Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)
	•	Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Trust’s own assumptions used in determining the face value of investments)
	The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

1. Organization and Significant Accounting Policies:

BlackRock Core Bond Trust (“BHK”), BlackRock Corporate High Yield Fund V, Inc. (“HYV”), BlackRock Corporate High Yield Fund VI, Inc. (“HYT”), BlackRock High Income Shares (“HIS”), BlackRock High Yield Trust (“BHY”), BlackRock Income Opportunity Trust, Inc. (“BNA”), BlackRock Income Trust, Inc. (“BKT”) and BlackRock Strategic Bond Trust (“BHD”) (collectively the “Trusts” or individually as the “Trust”) are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as diversified, closed-end management investment companies. HYV, HYT, BNA and BKT are organized as Maryland corporations. BHK, BHY and BHD are organized as Delaware statutory trusts. HIS is organized as a Massachusetts business trust. The Trusts’ financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The Boards of Directors and Boards of Trustees of the Trusts are referred to throughout this report as the “Board of Trustees” or the “Board.” The Trusts 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 Trusts:

Valuation: The Trusts’ policy is to fair value their financial instruments at market value. The Trusts value their bond investments on the basis of last available bid prices or current market quotations provided by dealers or pricing services selected under the supervision of each Trust’s Board. Floating rate loan interests are valued at the mean of the bid prices from one or more brokers or dealers as obtained from a pricing service. 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, various relationships observed in the market between investments and calculated yield measures based on valuation technology commonly employed in the market for such investments. Asset-backed and mortgage-backed securities are valued by independent pricing services using models that consider estimated cash flows of each tranche of the security, establishes a benchmark yield and develops an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche. Financial futures contracts traded on exchanges are valued at their last sale price. To be announced (“TBA”) commitments are valued at the current market value of the underlying securities. Swap agreements are valued utilizing quotes received daily by the Trusts’ pricing service or through brokers, which are derived using daily swap curves and trades of underlying securities. Investments in open-end investment companies are valued at net asset value each business day. Short-term securities with remaining maturities of 60 days or less may be valued at amortized cost, which approximates fair value.

Equity investments traded on a recognized securities exchange or the NASDAQ Global Market System are valued at the last reported sale price that day or the NASDAQ official closing price, if applicable. For equity investments traded on more than one exchange, the last reported sale price on the exchange where the stock is primarily traded is used. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last available bid (long positions) or ask (short positions) price. If no bid or ask price is available, the prior day’s price will be used, unless it is determined that such prior day’s price no longer reflects the fair value of the security.

Securities and other assets and liabilities denominated in foreign currencies are translated into US dollars using exchange rates determined as of the close of business on the New York Stock Exchange (“NYSE”). Foreign currency exchange contracts are valued at the mid between the bid and ask prices and are determined as of the close of business on the NYSE. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available.

Exchange-traded options are valued at the mean between the last bid and ask prices at the close of the options market in which the options trade. An exchange-traded option for which there is no mean price is valued at the last bid (long positions) or ask (short positions) price. If no bid or ask price is available, the prior day’s price will be used, unless it is determined that the day’s price no longer reflects the fair value of the option. Over-the-counter (“OTC”) options and swaptions are valued by an independent pricing service using a mathematical model which incorporates a number of market data factors, such as the trades and prices of the underlying instruments.

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 by a method approved by each Trust’s Board as reflecting fair value (“Fair Value Assets”). When determining the price for Fair Value Assets, the investment advisor and/or the sub-advisor seeks to determine the price that each Trust might reasonably expect to receive from the current sale of that asset in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the investment advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof.

Generally, trading in foreign instruments is substantially completed each day at various times prior to the close of business on the NYSE. Occasionally, events affecting the values of such instruments may occur between the foreign market close and the close of business on the NYSE that may not be reflected in the computation of the Trust’s net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such instruments, those instruments may be Fair Value Assets and be valued at their fair value, as determined in good faith by the Board or by the investment advisor using a pricing service and/or procedures approved by the Board.

Foreign Currency Transactions: Foreign currency amounts are translated into United States dollars on the following basis: (i) market value of investment securities, assets and liabilities at the current rate of exchange; and (ii) purchases and sales of investment securities, income and expenses at the rates of exchange prevailing on the respective dates of such transactions.

The Trusts report foreign currency related transactions as components of realized gains for financial reporting purposes, whereas such components are treated as ordinary income for federal income tax purposes.

SEMI-ANNUAL REPORT FEBRUARY 28, 2010 93

Notes to Financial Statements (continued)

Asset-Backed and Mortgaged-Backed Securities: Certain Trusts may invest in asset-backed securities. Asset-backed securities are generally issued as pass-through certificates, which represent undivided fractional ownership interests in an underlying pool of assets, or as debt instruments, which are also known as collateralized obligations, and are generally issued as the debt of a special purpose entity organized solely for the purpose of owning such assets and issuing such debt. Asset-backed securities are often backed by a pool of assets representing the obligations of a number of different parties. The yield characteristics of certain asset-backed securities may differ from traditional debt securities. One such major difference is that all or a principal part of the obligations may be prepaid at any time because the underlying assets (i.e., loans) may be prepaid at any time. As a result, a decrease in interest rates in the market may result in increases in the level of prepayments as borrowers, particularly mortgagors, refinance and repay their loans. An increased prepayment rate with respect to an asset-backed security subject to such a prepayment feature will have the effect of shortening the maturity of the security. If a Trust has purchased such an asset-backed security at a premium, a faster than anticipated prepayment rate could result in a loss of principal to the extent of the premium paid.

Certain Trusts may purchase certain mortgage pass-through securities. There are a number of important differences among the agencies and instrumentalities of the US Government that issue mortgage-related securities and among the securities that they issue. For example, mortgage-related securities guaranteed by the Government National Mortgage Association (“GNMA”) are guaranteed as to the timely payment of principal and interest by GNMA and such guarantee is backed by the full faith and credit of the United States. However, mortgage-related securities issued by the Federal Home Loan Mortgage Corporation (“FHLMC”) and Federal National Mortgage Association (“FNMA”), including FNMA guaranteed Mortgage Pass-Through Certificates which are solely the obligations of the FNMA, are not backed by or entitled to the full faith and credit of the United States and are supported by the right of the issuer to borrow from the Treasury.

Certain Trusts invest a significant portion of its assets in securities backed by commercial or residential mortgage loans or in issuers that hold mortgage and other asset-backed securities. Please see the Schedule of Investments for these securities. Changes in economic conditions, including delinquencies and/or defaults on assets underlying these securities, can affect the value, income and/or liquidity of such positions.

Multiple Class Pass-Through Securities: Certain Trusts may invest in multiple class pass-through securities, including collateralized mortgage obligations (“CMOs”) and commercial mortgage-backed securities. These multiple class securities may be issued by GNMA, US government agencies or instrumentalities or by trusts formed by private originators of, or investors in, mortgage loans. In general, CMOs are debt obligations of a legal entity that are collateralized by, and multiple class pass-through securities represent direct ownership interests in, a pool of residential or commercial mortgage loans or mortgage pass-through securities (the “Mortgage Assets”), the payments on which are used to make payments on the CMOs or multiple pass-through securities. Classes of CMOs include interest only (“IOs”), principal only (“POs”), planned amortization classes and targeted amortization classes. IOs and POs are stripped mortgage-backed securities representing interests in a pool of mortgages, the cash flow from which has been separated into interest and principal components. IOs receive the interest portion of the cash flow while POs receive the principal portion. IOs and POs can be extremely volatile in response to changes in interest rates. As interest rates rise and fall, the value of IOs tends to move in the same direction as interest rates. POs perform best when prepayments on the underlying mortgages rise since this increases the rate at which the investment is returned and the yield to maturity on the PO. When payments on mortgages underlying a PO are slower than anticipated, the life of the PO is lengthened and the yield to maturity is reduced. If the underlying mortgage assets experience greater than anticipated pre-payments of principal, the Trusts may not fully recoup its initial investment in IOs.

Capital Trusts: These securities are typically issued by corporations, generally in the form of interest-bearing notes with preferred securities characteristics, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The securities can be structured as either fixed or adjustable coupon securities that can have either a perpetual or stated maturity date. Dividends can be deferred without creating an event of default or acceleration, although maturity cannot take place unless all cumulative payment obligations have been met. The deferral of payments does not affect the purchase or sale of these securities in the open market. Payments on these securities are treated as interest rather than dividends for federal income tax purposes. These securities can have a rating that is slightly below that of the issuing company’s senior debt securities.

Preferred Stock: Certain Trusts may invest in preferred stocks. Preferred stock has a preference over common stock in liquidation (and generally in receiving dividends as well) but is subordinated to the liabilities of the issuer in all respects. As a general rule, the market value of preferred stock with a fixed dividend rate and no conversion element varies inversely with interest rates and perceived credit risk, while the market price of convertible preferred stock generally also reflects some element of conversion value. Because preferred stock is junior to debt securities and other obligations of the issuer, deterioration in the credit quality of the issuer will cause greater changes in the value of a preferred stock than in a more senior debt security with similar stated yield characteristics. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Floating Rate Loans: Certain Trusts may invest in floating rate loans, which are generally non-investment grade, made by banks, other financial institutions, and privately and publicly offered corporations. Floating rate loans are senior in the debt structure of a corporation. Floating rate loans generally pay interest at rates that are periodically determined by reference to a base lending rate plus a premium. The base lending rates are generally (i) the lending rate offered by one or more European banks, such as LIBOR (London Inter Bank Offered Rate), (ii) the prime rate offered by one or more US banks or (iii) the certificate of deposit rate. The Trusts consider these investments to be investments in debt securities for purposes of their investment policies.

The Trusts earn and/or pay facility and other fees on floating rate loans. Other fees earned/paid include commitment, amendment, consent and prepayment penalty fees. Facility, commitment and amendment fees are typically

94 SEMI-ANNUAL REPORT FEBRUARY 28, 2010

Notes to Financial Statements (continued)

amortized over the term of the loan. Consent fees and various other fees are recorded as income. Prepayment penalty fees are recorded as realized gains. When a Trust buys a floating rate loan it may receive a facility fee and when it sells a floating rate loan it may pay a facility fee. On an ongoing basis, the Trusts may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a floating rate loan. In certain circumstances, the Trusts may receive a prepayment penalty fee upon the prepayment of a floating rate loan by a borrower. Other fees received by the Trusts may include covenant waiver fees and covenant modification fees.

The Trusts may invest in multiple series or tranches of a loan. A different series or tranche may have varying terms and carry different associated risks.

Floating rate loans are usually freely callable at the issuer’s option. The Trusts may invest in such loans in the form of participations in loans (“Participations”) and assignments of all or a portion of loans from third parties. Participations typically will result in the Trusts having a contractual relationship only with the lender, not with the borrower. The Trusts will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the Participation and only upon receipt by the lender of the payments from the borrower.

In connection with purchasing Participations, the Trusts generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loans, nor any rights of offset against the borrower, and the Trusts may not benefit directly from any collateral supporting the loan in which it has purchased the Participation.

As a result, the Trusts will assume the credit risk of both the borrower and the lender that is selling the Participation. The Trusts’ investments in loan participation interests involve the risk of insolvency of the financial intermediaries who are parties to the transactions. In the event of the insolvency of the lender selling the Participation, the Trusts may be treated as a general creditor of the lender and may not benefit from any offset between the lender and the borrower.

Borrowed Bond Agreements: In a borrowed bond agreement, a Trust borrows securities from a third party, with the commitment that they will be returned to the lender on an agreed-upon date. Borrowed bond agreements are primarily entered into to settle short positions. In a borrowed bond agreement, the Trust’s prime broker or third party broker takes possession of the underlying collateral securities or cash to settle such short positions. The value of the underlying collateral securities or cash approximates the principal amount of the borrowed bond transaction, including accrued interest. To the extent that borrowed bond transactions exceed one business day, the value of the collateral with any counterparty is marked to market on a daily basis to ensure the adequacy of the collateral. If the lender defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the lender of the security, realization of the collateral by the Trust may be delayed or limited.

Mortgage Dollar Roll Transactions: Certain Trusts may sell mortgage-backed securities and simultaneously contract to repurchase substantially similar (same type, coupon and maturity) securities on a specific future date at an agreed-upon price. During the period between the sale and repurchase, the Trusts will not be entitled to receive interest and principal payments on the securities sold. The Trusts account for dollar roll transactions as purchases and sales and realize gains and losses on these transactions. Mortgage dollar rolls involve the risk that the market value of the securities that the Trusts are required to purchase may decline below the agreed upon repurchase price of those securities.

Treasury Roll Transactions: A treasury roll transaction involves the sale of a Treasury security, with an agreement to repurchase the same security at an agreed upon price and date. Treasury rolls constitute a borrowing and the difference between the sale and repurchase price represents interest expense at an agreed upon rate. Whether such a transaction produces a positive impact on performance depends upon whether the income and gains on the securities purchased with the proceeds received from the sale of the security exceeds the interest expense incurred by the Master Portfolio. Treasury rolls are not considered purchases and sales and any gains or losses incurred on the treasury rolls will be deferred until the Treasury securities are disposed.

Treasury roll transactions involve the risk that the market value of the securities that the Trusts are required to purchase may decline below the agreed upon purchase price of those securities. If investment performance of securities purchased with proceeds from these transactions does not exceed the income, capital appreciation and gain or loss that would have been realized on the securities sold as part of the treasury roll, the use of this technique will adversely impact the investment performance of the Trusts

Reverse Repurchase Agreements: Certain Trusts may enter into reverse repurchase agreements with qualified third party broker-dealers. In a reverse repurchase agreement, the Trusts sell securities to a bank or broker-dealer and agrees to repurchase the securities at a mutually agreed upon date and price. Certain agreements have no stated maturity and can be terminated by either party at any time. Interest on the value of the reverse repurchase agreements issued and outstanding is based upon competitive market rates determined at the time of issuance. The Trusts may utilize reverse repurchase agreements when it is anticipated that the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities that the Trusts are obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Trusts’ use of the proceeds of the agreement may be restricted while the other party, or its trustee or receiver, determines whether or not to enforce the Trusts’ obligation to repurchase the securities.

TBA Commitments: Certain Trusts may enter into TBA commitments to purchase or sell securities for a fixed price at a future date. TBA commitments involve a risk of loss if the value of the security to be purchased or sold declines or increases prior to settlement date, which is in addition to the risk of decline in the value of the Trusts’ other assets.

Zero-Coupon Bonds: Each Trust 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.

Notes to Financial Statements (continued)

Segregation and Collateralization: In cases in which the 1940 Act and the interpretive positions of the SEC require that the Trusts either delivers collateral or segregate assets in connection with certain investments (e.g., dollar rolls, TBAs beyond normal settlement, financial futures contracts, foreign currency exchange contracts, swaps, short sales and written options), or certain borrowings (e.g., reverse repurchase agreements, treasury rolls and loan payable) each Trust will, consistent with SEC rules and/or certain interpretive letters issued by the SEC, segregate collateral or designate on its books and records cash or other liquid securities having a market value at least equal to the amount that would otherwise be required to be physically segregated. 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 transactions are entered into (the trade dates). Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Trust has determined the ex-dividend date. Interest income is recognized on the accrual basis. The Trusts amortizes all premiums and discounts on debt securities. Consent fees are compensation for agreeing to changes in the terms of debt instruments and are included in interest income in the Statements of Operations.

Dividends and Distributions: Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. If the total dividends and distributions made in any tax year exceeds net investment income and accumulated realized capital gains, a portion of the total distribution may be treated as a tax return of capital.

Income Taxes: It is each Trust’s policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. Under the applicable foreign tax laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates.

Each Trust files US federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on BHK, BHY, BNA, BKT and BHD’s US federal tax returns remains open for the two years ended October 31, 2007, the period ended August 31, 2008 and the year ended August 31, 2009. The statute of limitations on BHK and HIS’s US federal tax returns remains open for the two years ended December 31, 2007, the period ended August 31, 2008 and the year ended August 31, 2009. The statute of limitations on the HYV and HYT’s tax returns remains open for the four years ended August 31, 2009. The statutes of limitations on the Trusts’ state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Recent Accounting Standards: In June 2009, amended guidance was issued by the Financial Accounting Standards Board (“FASB”) for transfers of financial assets. This guidance is intended to improve the relevance, representational faithfulness and comparability of the information that a reporting entity provides in its financial statements about a transfer of financial assets; the effects of a transfer on its financial position, financial performance, and cash flows; and a transferor’s continuing involvement, if any, in transferred financial assets. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after November 15, 2009. Earlier application is prohibited. The recognition and measurement provisions of this guidance must be applied to transfers occurring on or after the effective date. Additionally, the enhanced disclosure provisions of the amended guidance should be applied to transfers that occurred both before and after the effective date of this guidance. The impact of this guidance on the Trusts’ financial statements and disclosures, if any, is currently being assessed.

In January 2010, the FASB issued amended guidance to improve disclosure about fair value measurements which will require additional disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances and settlements in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). It also clarifies existing disclosure requirements relating to the levels of disaggregation for fair value measurement and inputs and valuation techniques used to measure fair value. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after December 15, 2009 except for disclosures about purchases, sales, issuances and settlements in the rollforward of activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. The impact of this guidance on the Trusts’ financial statements and disclosures is currently being assessed.

Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by each Trust’s Board, non-interested Trustees (“Independent Trustees”) 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 Trustees. This has approximately the same economic effect for the Independent Trustees as if the Independent Trustees had invested the deferred amounts directly in other certain BlackRock Closed-End Funds.

The deferred compensation plan is not funded and obligations there under represent general unsecured claims against the general assets of each Trust. Each Trust may, however, elect to invest in common shares of other certain BlackRock Closed-End Funds selected by the Independent Trustees in order to match its deferred compensation obligations. Investments to cover each Trust’s deferred compensation liability, if any, are included in other assets in the Statements of Assets and Liabilities. Dividends and distributions from the BlackRock Closed-End Funds investments under the plan are included in income — affiliated in the Statements of Operations.

Other: Expenses directly related to a Trust are charged to that Trust. 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 Trusts have an arrangement with the custodian 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 Operations. The custodian

96 SEMI-ANNUAL REPORT FEBRUARY 28, 2010

Notes to Financial Statements (continued)

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

2. Derivative Financial Instruments:

Each Trust may engage in various portfolio investment strategies both to increase the returns of the Trusts and to economically hedge, or protect, their exposure to certain risks such as credit risk, equity risk, interest rate risk and foreign currency exchange rate risk. Losses may arise if the value of the contract decreases due to an unfavorable change in the price of the underlying instrument or if the counterparty does not perform under the contract. The Trusts may mitigate counterparty risk through master netting agreements included within an International Swap and Derivatives Association, Inc. (“ISDA”) Master Agreement between a Trust and each of its counterparties. The ISDA Master Agreement allows each Trust to offset with its counterparty certain derivative financial instrument’s payables and/or receivables with collateral held with each counterparty. The amount of collateral moved to/from applicable counterparties is based upon minimum transfer amounts of up to $500,000. To the extent amounts due to the Trusts from their counterparties are not fully collateralized contractually or otherwise, the Trusts bear the risk of loss from counterparty non-performance. See Note 1 “Segregation and Collateralization” for information with respect to collateral practices.

The Trust’s maximum risk of loss from counterparty credit risk on OTC derivatives is generally the aggregate unrealized gain in excess of any collateral pledged by the counterparty to the Trusts. For OTC options purchased, the Trusts bears the risk of loss in the amount of the premiums paid and change in market value of the options should the counterparty not perform under the contracts. Options written by the Trusts do not give rise to counterparty credit risk, as options written obligate the Trusts to perform and not the counter-party. Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Trust’s net assets decline by a stated percentage or the Trust fails to meet the terms of its ISDA Master Agreements, which would cause the Trust to accelerate payment of any net liability owed to the counterparty. Counterparty risk related to exchange-traded financial futures contracts and options is minimal because of the protection against defaults provided by the exchange on which they trade.

Financial Futures Contracts: The Trusts may 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) or foreign currencies (foreign currency exchange 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 Trusts 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 Trusts as unrealized gains or losses. When the contract is closed, the Trusts 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 financial futures contracts, interest or foreign currency exchange rates and the underlying assets.

Foreign Currency Exchange Contracts: The Trusts may enter into foreign currency exchange contracts as an economic hedge against either specific transactions or portfolio positions (foreign currency exchange rate risk). A foreign currency exchange contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a future date. Foreign currency exchange contracts, when used by the Trusts, help to manage the overall exposure to the currency backing some of the investments held by the Trusts. The contract is marked-to-market daily and the change in market value is recorded by the Trusts as an unrealized gain or loss. When the contract is closed, the Trusts record a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. The use of foreign currency exchange contracts involves the risk that counterparties may not meet the terms of the agreement or unfavorable movements in the value of a foreign currency relative to the US dollar.

Options: The Trusts may purchase and write call and put options to increase or decrease their exposure to underlying instruments (equity risk) and/or, in the case of options written, to generate gains from options premiums. A call option gives the purchaser of the option the right (but not the obligation) to buy, and obligates the seller to sell (when the option is exercised), the underlying instrument at the exercise price at any time or at a specified time during the option period. A put option gives the holder the right to sell and obligates the writer to buy the underlying instrument at the exercise price at any time or at a specified time during the option period. When a Trust purchases (writes) an option, an amount equal to the premium paid (received) by a Trust is reflected as an asset (liability). The amount of the asset (liability) is subsequently marked-to-market to reflect the current market value of the option purchased (written).When an instrument is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the instrument acquired or deducted from (or added to) the proceeds of the instrument sold. When an option expires (or a Trust enters into a closing transaction), a Trust realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium received or paid). When a Trust writes a call option, such option is “covered,” meaning that a Trust holds the underlying instrument subject to being called by the option counterparty, or cash in an amount sufficient to cover the obligation. When a Trust writes a put option, such option is covered by cash in an amount sufficient to cover the obligation.

Options on swaps (swaptions) are similar to options on securities except that instead of selling or purchasing the right to buy or sell a security, the writer or purchaser of the swap option is granting or buying the right to enter into a previously agreed upon interest rate swap agreement at any time before the expiration of the option.

The Portfolios may also purchase or sell listed or OTC foreign currency options, foreign currency futures and related options on foreign currency futures as a short or long hedge against possible variations in foreign exchange rates. When foreign currency is purchased or sold through an exercise of a foreign currency option, the related premium paid (or received) is added to (or deducted from) the basis of the foreign currency acquired or deducted from (or added to) the proceeds of the foreign currency sold. Such transactions may be effected with respect to hedges on non-US dollar

SEMI-ANNUAL REPORT FEBRUARY 28, 2010 97

Notes to Financial Statements (continued)

denominated securities owned by the Portfolios but not yet delivered, or committed or anticipated to be purchased by the Portfolios.

In purchasing and writing options, a Trust bears the risk of an unfavorable change in the value of the underlying instrument or the risk that a Trust may not be able to enter into a closing transaction due to an illiquid market. Exercise of an option written could result in a Trust purchasing or selling a security at a price different from the current market value. The Trusts may execute transactions in both listed and OTC options.

Swaps: Each Trust may enter into swap agreements, in which a Trust and a counterparty agree to make periodic net payments on a specified notional amount. These periodic payments received or made by the Trusts are recorded in the Statements of Operations as realized gains or losses, respectively. Any upfront fees paid are recorded as assets and any upfront fees received are recorded as liabilities and amortized over the term of the swap. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). When the swap is terminated, the Trust will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Trust’s basis in the contract, if any. Swap transactions involve, to varying degrees, elements of interest rate, credit and market risk in excess of the amounts recognized in the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counter-party to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

• Credit default swaps — The Trusts may enter into credit default swaps to manage its exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults of corporate and/or sovereign issuers or to create exposure to corporate and/or sovereign issuers to which it is not otherwise exposed (credit risk). The Trusts enter into credit default agreements to provide a measure of protection against the default of an issuer (as buyer protection) and/or gain credit exposure to an issuer to which it is not otherwise exposed (as seller of protection). The Trust may either buy or sell (write) credit default swaps on single-name issuers (corporate or sovereign) or traded indexes. Credit default swaps on single-name issuers are agreements in which the buyer pays fixed periodic payments to the seller in consideration for a guarantee from the seller to make a specific payment should a negative credit event take place (e.g., bankruptcy, failure to pay, obligation accelerators, repudiation, moratorium or restructuring). Credit default swaps on traded indexes are agreements in which the buyer pays fixed periodic payments to the seller in consideration for a guarantee from the seller to make a specific payment should a write-down, principal or interest shortfall or default of all or individual underlying securities included in the index occurs. As a buyer, if an underlying credit event occurs, a Trust will either receive from the seller an amount equal to the notional amount of the swap and deliver the referenced security or underlying securities comprising of an index or receive a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising of an index. As a seller (writer), if an underlying credit event occurs, a Trust will either pay the buyer an amount equal to the notional amount of the swap and take delivery of the referenced security or underlying securities comprising of an index or pay a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising of an index.

• Interest rate swaps — Each Trust may enter into interest rate swaps to manage duration, the yield curve or interest rate risk by economically hedging the value of the fixed rate bonds which may decrease when interest rates rise (interest rate risk). Interest rate swaps are agreements in which one party pays a floating rate of interest on a notional principal amount and receives a fixed rate of interest on the same notional principal amount for a specified period of time. Interest rate floors, which are a type of interest rate swap, are agreements in which one party agrees to make payments to the other party to the extent that interest rates fall below a specified rate or floor in return for a premium. In more complex swaps, the notional principal amount may decline (or amortize) over time.

• Total return swaps — Each Trust may enter into total return swaps to transfer the risk/return of one market (e.g., fixed income) to another market (e.g., equity) (equity risk and/or interest rate risk). Total return swaps are agreements in which one party commits to pay interest in exchange for the total return (coupons plus capital gains/losses) of an underlying asset. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the Trust will receive a payment from or make a payment to the counterparty.

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 structure, PNC is an affiliate for 1940 Act purposes, but BAC and Barclays are not.

Each Trust entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Manager”), the Trusts’ investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services for BHK, HYV, HYT, HIS, and BHD.

The following Trusts’ investment advisory fee paid to the Manager is computed weekly and payable monthly based on an annual rate of each Trust’s average total assets (including any assets attributable to borrowings) minus the sum of total liabilities (other than debt representing financial leverage):

BHK	0.55%
HIS	0.75% of the first $200 million and 0.50% thereafter
BHY	1.05%
BHD	0.75%

The following Trusts’ investment advisory fee paid to the Manager is computed daily and payable monthly based on an annual rate of each Trust’s average total assets (including any assets attributable to borrowings) minus the sum of total liabilities (other than debt representing financial leverage):

HYV	0.60%
HYT	0.70%

The following Trusts’ investment advisory fee paid to the Manager is computed weekly and payable monthly based on an annual rate of each Trust’s average net assets:

BNA	0.60%
BKT	0.65%

The Manager has voluntarily agreed to waive a portion of the investment advisory fees or other expenses on BHD by 0.05% of its average weekly managed assets through February 28, 2010. This amount is included in fees waived by advisor on the Statements of Operations. For the six months ended February 28, 2010, the amount waived by BHD was $22,435.

BHY, BNA and BKT each have an Administration Agreement with the Manager. The administration fee paid to the Manager is computed weekly and payable monthly based on an annual rate, 0.10% for BNA, and 0.15% for BKT, of each Trust’s average net assets and 0.10% for BHY of the Trust’s average weekly managed assets.

Notes to Financial Statements (continued)

The Manager has voluntarily agreed to waive its advisory fees by the amount of investment advisory fees each Trust pays to the Manager indirectly through its investment in affiliated money market funds, however the Manager does not waive its advisory fees by the amount of investment advisory fees through its investment in other affiliated investment companies.

5. Commitments:

Certain Trusts may invest in floating rate loans. In connection with these investments, the Trusts may also enter into unfunded corporate loans (“commitments”). Commitments may obligate the Trusts to furnish temporary financing to a borrower until permanent financing can be arranged. In connection with these commitments, the Trusts earn a commitment fee, typically set as a percentage of the commitment amount. Such fee income, which is classified in the Statements of Operations as facility and other fees, is recognized ratably over the commitment period. As of February 28, 2010, the following commitments were:

Borrower	Unfunded Commitment		Value of Underlying Loans
BHK
Cox Enterprises	$	1,950,000	$	1,966,468
HYV
Delphi International Holdings	$	1,277,361	$	1,106,639

7. Market and Credit Risk:

In the normal course of business, the Trusts invest in securities and enter into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations (credit risk). The value of securities held by the Trusts may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Trusts; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to credit risk, the Trusts may be exposed to counterparty risk, or the risk that an entity with which the Trusts have unsettled or open transactions may default. Financial assets, which potentially expose the Trusts to credit and counterparty risks, consist principally of investments and cash due from counterparties. The extent of the Trusts’ exposure to credit and counterparty risks with respect to these financial assets is generally approximated by their value recorded in the Trusts’ Statements of Assets and Liabilities, less any collateral held by the Trusts.

8. Capital Share Transactions:

There are 200 million of $0.01 par value shares authorized for BNA and BKT. There are an unlimited number of $0.001 par value shares authorized for BHK, BHY and BHD. There are an unlimited number of no par value shares authorized for HIS. There are 200 million of $0.10 par value shares authorized for HYV and HYT.

102 SEMI-ANNUAL REPORT FEBRUARY 28, 2010

Notes to Financial Statements (continued)

During the six months ended February 28, 2010 and the year ended August 31, 2009, the shares issued and outstanding increased by the following amounts as a result of dividend reinvestment:

	Six Months Ended February 28, 2010		Year Ended August 31, 2009
BHK		—		4,253
BHY		—		8,666
BNA		—		6,677

Shares issued and outstanding remained constant during the six months ended February 28, 2010 and the year ended August 31, 2009 for HYV, HYT, HIS, BKT and BHD.

9. Borrowings:

On March 5, 2009, HYV, HVT, HIS and BHY entered into a senior committed secured, 364-day revolving line of credit and a separate security agreement (the “SSB Agreement”) with State Street Bank and Trust Company (“SSB”). The Trusts have granted a security interest in substantially all of their assets to SSB. The agreement allowed for the maximum commitment amounts:

	Commitment Amount
HYV	$	127,000,000
HYT	$	135,000,000
HIS	$	41,000,000
BHY	$	16,000,000

Advances are made by SSB to the Trusts, at the Trusts’ option of (a) the higher of (i) 1.0% above the Fed Effective Rate and (ii) 1.0% above the Overnight LIBOR or (b) 1.0% above 7-day, 30-day, 60-day or 90-day LIBOR. In addition, the Trusts pay a facility fee and a commitment fee based upon SSB’s total commitment to the Trusts. The fees associated with each of the agreements are included in the Statements of Operations as borrowing costs. Advances to the Trusts as of February 28, 2010 are shown in the Statements of Assets and Liabilities as loan payable. The SSB Agreement was renewed for 364 days under substantially the same terms effective March 4, 2010. In addition, BHD entered into the SSB Agreement. The agreement allows for the following maximum commitment amounts:

	Commitment Amount
HYV	$	140,000,000
HYT	$	145,000,000
HIS	$	45,000,000
BHY	$	18,000,000
BHD	$	30,000,000

The Trusts may not declare dividends or make other distributions on shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding short-term borrowings is less than 300%.

On August 28, 2009, BHK, BNA and BKT borrowed under the Term Asset-Backed Securities Loan Facility (“TALF”). The TALF program was launched by the U.S. Department of Treasury and the Federal Reserve Board as a credit facility designed to restore liquidity to the market for asset-backed securities. The Federal Reserve Bank of New York (“FRBNY”) will provide up to $1 trillion in non-recourse loans to support the issuance of certain AAA-rated asset-backed securities and commercial mortgage-backed securities (“Eligible Securities”). Each Trust posted as collateral already-held Eligible Securities, which were all commercial mortgage-backed securities, in return for non-recourse, 5-year term loans (“TALF loans”) in an amount equal to approximately 85% of the value of such Eligible Securities. The TALF loans are shown as loans payable on the Statements of Assets and Liabilities. The following is a summary of the outstanding TALF loans and related information as of February 28, 2010:

	Number of Loans	Aggregate Amount of Loans		Maturity Date(s)	Interest Rates	Value of Eligible Securities
BHK	1	$	11,805,458	8/28/14	3.87%	$	14,417,848
BNA	1	$	11,805,458	8/28/14	3.87%	$	14,417,848
BKT	1	$	11,775,941	8/28/14	3.87%	$	14,476,036

The non-recourse provision of the TALF loans allows the Trusts to satisfy loan obligations with Eligible Securities, subject to certain conditions, even if the value of the Eligible Securities falls below the outstanding amount of the loan. The Trusts can repay TALF loans prior to the maturity dates with no penalty. Principal and interest due on the loans will typically be paid with principal paydowns and interest received from the Eligible Securities. Credit agreements underlying each loan contain provisions to address instances in which interest payments on Eligible Securities fall short of amounts due to the FRBNY. The Trusts paid to the FRBNY a one time administration fee of 0.20% of the amount borrowed, which was expensed as incurred in the current period by the Trusts and is included in borrowing costs in the Statements of Operations. Each Trust also pays a financing fee equal to the 5-year LIBOR swap rate plus 1.00% on the outstanding loan amount payable monthly, which is included in interest expense in the Statements of Operations.

Since the Trusts have the ability to potentially satisfy TALF loan obligations by surrendering Eligible Securities, potential losses by the Trusts associated with the TALF loans are limited to the difference between the amount of Eligible Securities posted at the time of loan initiation and the loan proceeds received by the Trusts.

The Trusts have elected to account for the outstanding TALF loans at fair value. The Trusts elected to fair value its TALF loans to more closely align changes in the value of the TALF loans with changes in the value of the Eligible Securities and to reduce the potential volatility in the Statements of Operations which could result if only the Eligible Securities were fair valued. In fair valuing TALF loans, the Trusts considers various factors such as observable market transactions, if available, changes in the value of Eligible Securities, interest rate movements, and the potential likelihood and timing of loan repayments. Any change in unrealized gain or loss associated with fair valuing TALF loans will be reflected in the Statements of Operations. As of February 28, 2010, the fair value of each Trust’s TALF loan obligation was determined to be equal to its face value and as a result there were no unrealized gains or losses recorded by the Trusts.

Additional Information

Dividend Policy

The Trusts’ dividend policy is to distribute all or a portion of their net investment income to their shareholders on a monthly basis. In order to provide shareholders with a more stable level of dividend distributions, the Trusts 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 Trusts for any particular month may be more or less than the amount of net investment income earned by the Trusts during such month. The Trusts’ current accumulated but undistributed net investment income, if any, is disclosed in the Statements of Assets and Liabilities, which comprises part of the financial information included in this report.

General Information

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

During the period, there were no material changes in the Trusts’ investment objectives or policies or to the Trusts’ charter or by-laws that were not approved by the shareholders or in the principal risk factors associated with investment in the Trusts. Other than as disclosed below, there have been no changes in the persons who are primarily responsible for the day-to-day management of the Trusts’ portfolio.

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

Electronic Delivery

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

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

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

Householding

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

Availability of Quarterly Schedule of Investments

Each Trust files its complete schedule of portfolio holdings with the Securities and Exchange Commission (“SEC”) for the first and third quarters of each fiscal year on Form N-Q. The Trusts’ Forms N-Q are available on the SEC’s website at http://www.sec.gov and may also be reviewed and copied at the SEC’s Public Reference Room in Washington, DC. Information on the operation of the Public Reference Room may be obtained by calling (202) 551-8090. Each Trust’s Forms N-Q may also be obtained upon request and without charge by calling (800) 441-7762.

Availability of Proxy Voting Policies and Procedures

A description of the policies and procedures that the Trusts use to determine how to vote proxies relating to portfolio securities is available (1) without charge, upon request, by calling (800) 441-7762; (2) at www.blackrock.com; and (3) on the SEC’s website at http://www.sec.gov.

Availability of Proxy Voting Record

Information about how the Trusts voted proxies relating to securities held in the Trusts’ portfolios during the most recent 12-month period ended June 30 is available upon request and without charge (1) at www.blackrock.com or by calling (800) 441-7762 and (2) on the SEC’s website at http://www.sec.gov.

106 SEMI-ANNUAL REPORT FEBRUARY 28, 2010

Additional Information (concluded)

Section 19(a) Notices

These reported amounts and sources of distributions are estimates and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon each Trust’s investment experience during the year and may be subject to changes based on the tax regulations. Each Trust will provide a Form 1099-DIV each calendar year that will explain the character of these dividends and distributions for federal income tax purposes.

February 28, 2010
	Total Cumulative Distributions for the Fiscal Year-to-Date							% Breakdown of the Total Cumulative Distributions for the Fiscal Year-to-Date
	Net Investment Income		Net Realized Capital Gains	Return of Capital		Total Per Common Share		Net Investment Income	Net Realized Capital Gains	Return of Capital	Total Per Common Share
BHY	$	0.24931	—	$	0.01169	$	0.26100	96%	—	4%	100%

Each Trust estimates that it has distributed more than the amount of earned income and net realized gains; therefore, a portion of the distribution may be a return of capital. A return of capital may occur, for example, when some or all of the shareholder’s investment in a Trust is returned to the shareholder. A return of capital does not necessarily reflect a Trust’s investment performance and should not be confused with ‘yield’ or ‘income.’
