2	ANNUAL REPORT	AUGUST 31, 2008

A Letter to Shareholders

Dear Shareholder

It has been a tumultuous year for investors, marked by almost daily headlines related to the beleaguered housing market, rising food and energy prices, and the escalating credit crisis. The news took an extraordinarily heavy tone shortly after the close of this reporting period as the credit crisis boiled over and triggered unprecedented failures and consolidation in the financial sector, stoking fears of a market and economic collapse and prompting the largest government rescue plan since the Great Depression.

Through it all, the Federal Reserve Board (the “Fed”) has been aggressive in its attempts to restore order in financial markets. Key moves included slashing the target federal funds rate 325 basis points (3.25%) between September 2007 and April 2008 and providing numerous cash injections and lending programs. As the credit crisis took an extreme turn for the worse in September, the Fed, in concert with five other global central banks, cut interest rates by 50 basis points in a rare move intended to stave off worldwide economic damage from the intensifying financial market turmoil. The U.S. economy managed to grow at a slow-but-positive pace through the second quarter of the year, though the recent events almost certainly portend a global economic recession.

Against this backdrop, U.S. stocks experienced intense volatility (steep declines and quick recoveries), generally posting losses for the current reporting period. Small-cap stocks fared significantly better than their larger counterparts. Non-U.S. markets followed the U.S. on the way down and, notably, decelerated at a faster pace than domestic equities — a stark reversal of recent years’ trends, when international stocks generally outpaced U.S. stocks.

Treasury securities also traded in a volatile fashion, but rallied overall (yields fell and prices correspondingly rose), as the broader flight-to-quality theme persisted. The yield on 10-year Treasury issues, which fell to 3.34% in March, climbed to the 4.20% range in mid-June as investors temporarily shifted out of Treasury issues in favor of riskier assets (such as stocks and other high-quality fixed income sectors), then declined again to 3.83% by period-end when credit fears resurfaced. Tax-exempt issues posted positive returns, but problems among municipal bond insurers and the collapse in the market for auction rate securities pressured the group throughout the course of the past year. Economic and financial market distress also dampened the performance of high yield issues, which were very volatile due to the macro factors noted above.

Overall, severe market instability resulted in mixed results for the major benchmark indexes:

Trust Summary as of August 31, 2008	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.

Performance

	For the 12 months ended August 31, 2008, the Trust returned (0.44)% based on market price and 1.87% 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 0.76% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s allocation to mortgage-backed securities (MBS) which comprised 43% of net assets as of August 31, 2008, benefited performance as MBS outperformed corporate bonds. Conversely, allocations to high yield and preferred securities detracted from performance. The Trust’s lower leverage position versus its peers (about 24% of the portfolio as of August 31, 2008) also hurt performance.

	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 August 31, 2008	BlackRock High Income Shares


Investment Objective

	BlackRock High Income Shares (HIS) (the “Trust”) seeks to provide the highest current income and to a lesser extent capital appreciation, by investing in a diversified portfolio of below investment grade securities.

Performance

	For the 12 months ended August 31, 2008, the Trust returned (11.04)% based on market price and (3.17)% based on NAV. For the same period, the closed-end Lipper High Current Yield Funds (Leveraged) category posted an average return of (14.03)% on a NAV basis. All returns reflect reinvestment of dividends. Amid considerable volatility in credit markets, the Trust’s relative performance was aided by conservative positioning, with higher-than-normal credit quality, defensive sector positioning, an allocation to bank loans, and higher-than-normal cash balances. The Trust had much lower leverage (18% as of August 31, 2008) than most of its peers, which also aided relative performance. The Trust’s discount to NAV, which widened from 13.4% to 15.7% during the period, accounts for the difference between performance based on price and performance based on NAV.

Trust Summary as of August 31, 2008	BlackRock Income Opportunity Trust


Investment Objective

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

Performance

	For the 12 months ended August 31, 2008, the Trust returned 4.76% based on market price and 1.94% based on NAV. For the same period, the closed-end Lipper Corporate Debt Funds BBB-Rated category posted an average return of 0.76% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s relative performance was aided by holdings in U.S. government agency mortgage-backed securities. Conversely, holdings in investment-grade financials, non-agency mortgage securities, high yield bonds and preferred securities detracted from results. The Trust had much lower leverage (22% as of August 31, 2008) than its peers, which also hurt performance. The Trust’s discount to NAV, which narrowed modestly during the period, accounts for the difference between performance based on price and performance based on NAV.

Trust Summary as of August 31, 2008	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.

Performance

	For the 12 months ended August 31, 2008, the Trust returned 6.59% based on market price and 11.98% based on NAV. For the same period, the closed-end Lipper U.S. Mortgage Funds category posted an average return of 1.41% on a NAV basis. All returns reflect reinvestment of dividends. The primary driver behind the Trust’s relative outperformance was its large allocation to U.S. government agency mortgage-backed securities (MBS). Meanwhile, small allocations to non-agency MBS and other structured securities detracted from results. The Trust had much lower leverage during the period than its peers, which also hurt performance. The Trust’s discount to NAV, which widened modestly during the period, accounts for the difference between performance based on price and performance based on NAV.

Performance
	For the 12 months ended August 31, 2008, the Trust returned (7.37)% based on market price and 0.58% based on NAV.

Trust Summary as of August 31, 2008	BlackRock Strategic Bond Trust


Investment Objective

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

Performance
	For the 12 months ended August 31, 2008, the Trust returned (2.53)% based on market price and 1.49% based on NAV. For the same period, the closed-end Lipper General Bond Funds category posted an average return of 2.15% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s allocation to high yield loans (5% of net assets as of August 31, 2008) hurt relative performance as the Trust is in a general bond fund category and high yield bonds underperformed investment-grade bonds. The Trust’s discount to NAV, which widened modestly during the period, accounts for the difference between performance based on price and performance based on NAV.

The Benefits and Risks of Leveraging

The Trusts may utilize leverage through borrowings or issuance of short-term debt securities. 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 yield.

Leverage creates risks for shareholders including the likelihood of greater NAV and market price volatility. In addition, there is the risk that fluctuations in interest rates on borrowings may reduce each Trust’s yield and negatively impact its NAV and market price. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, the 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, the 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.

Under the Investment Company Act of 1940, the Trusts are permitted to borrow through a credit facility and the issuance of short-term debt securities up to 33¹/₃% of total managed assets. As of August 31, 2008, the Trusts had outstanding leverage from short-term debt securities or credit facility borrowings as a percentage of total managed assets as follows:



	Percent of Leverage

BlackRock Core Bond Trust	24	%
BlackRock High Income Shares	18	%
BlackRock High Yield Trust	12	%
BlackRock Income Opportunity Trust	22	%
BlackRock Limited Duration Income Trust, Inc.	9	%
BlackRock Strategic Bond Trust	2	%

Swap Agreements

The Trusts may invest in swap agreements, which are over-the-counter contracts in which one party agrees to make periodic payments based on the change in market value of a specified bond, basket of bonds, or index in return for periodic payments based on a fixed or variable interest rate or the change in market value of a different bond, basket of bonds or index. Swap agreements may be used to obtain exposure to a bond or market without owning or taking physical custody of securities. Swap agreements involve the risk that the party with whom the Trusts have entered into a swap will default on its obligation to pay the Trusts and the risk that the Trusts will not be able to meet their obligations to pay the other party to the agreement.

•	Effective January 1, 2008, the Trust adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“FAS 157”). FAS 157 clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. Various inputs are used in determining the fair value of investments, which are as follows:

	•	Level 1 - price quotations in active markets/exchanges for identical securities
	•	Level 2 - other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are 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 circumstance, to the extent observable inputs are not available (including the Trust’s own assumption 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.

The following table summarizes the inputs used as of August 31, 2008 in determining the fair valuation of the Trust’s investments:

Notes to Financial Statements

Note 1. Significant Accounting Policies:

BlackRock Core Bond Trust (“Core Bond”), BlackRock High Income Shares (‘High Income”), BlackRock High Yield Trust (“High Yield”), BlackRock Income Opportunity Trust, Inc. (“Income Opportunity”), BlackRock Income Trust, Inc. (“Income Trust”), BlackRock Limited Duration Income Trust (“Limited Duration”) and BlackRock Strategic Bond Trust (“Strategic Bond”) are registered as diversified, closed-end management investment companies under the Investment Company Act of 1940 (the “1940 Act”), as amended. Income Opportunity and Income Trust are organized as Maryland corporations. Core Bond, High Yield, Limited Duration and Strategic Bond are organized as Delaware statutory trusts. High Income is organized as a Massachusetts business trust. Core Bond, High Income, High Yield, Income Opportunity, Income Trust, Limited Duration and Strategic Bond, are individually referred to as a “Trust” and collectively as the “Trusts”. 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 Trusts recently changed their fiscal year end to August 31. 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 of Investments: 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 of Directors or Trustees, as appropriate (the “Board”). Floating rate loan interests are valued at the mean between the last available 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. Financial futures contracts traded on exchanges are valued at their last sale price. TBA commitments are valued at the current market value of the underlying securities. Swap agreements are valued by quoted fair values received daily by the Trusts’ pricing service or through brokers. Short-term securities are valued at amortized cost. Investments in open-end investment companies are valued at net asset value each business day.

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.

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 and previously were valued at the last sales price as of the close of options trading on applicable exchanges. 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 prior day’s price no longer reflects the fair value of the option. Over-the-counter options are valued by an independent pricing service using a mathematical model which incorporates a number of market data factors.

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the market value of such investment, the investment will be valued by a method approved by the Board as reflecting fair value (“Fair Value Assets”). When determining the price for Fair Value Assets, the investment advisor and/or 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 securities is substantially completed each day at various times prior to the close of business on the New York Stock Exchange (“NYSE”). The values of such securities used in computing the net assets of each Trust are determined as of such times. Foreign currency exchange rates will be determined as of the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of each 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 securities, those securities may 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.

Derivative Financial Instruments: Each Trust may engage in various portfolio investment strategies both to increase the returns of the Trusts and to hedge, or protect, their exposure to interest rate movements and movements in the securities markets. Losses may arise if the value of the contract decreases due to an unfavorable change in the price of the underlying security, or if the counterparty does not perform under the contract.

•

Financial futures contracts — Each Trust may purchase or sell financial futures contracts and options on such financial futures contracts. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Trust deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Trust agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in



ANNUAL REPORT	AUGUST 31, 2008	75




Notes to Financial Statements (continued)


	value of the contract. Such receipts or payments are known as margin variation and are recognized by the Trust as unrealized gains or losses. When the contract is closed, the Trust records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

•	Foreign currency exchange contracts — Each Trust may enter into foreign currency exchange contracts as a hedge against either specific transactions or portfolio positions. Foreign currency exchange contracts, when used by the Trusts, help to manage the overall exposure to the foreign 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.

•	Options — Each Trust may purchase and write call and put options. When a Trust writes an option, an amount equal to the premium received by the Trusts is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Trusts enter into a closing transaction), the Trusts realize 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).

	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 position 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 position at the exercise price at any time or at a specified time during the option period.

•	Swaps — Each Trust may enter into swap agreements, in which the 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 accompanying Statements of Operations as realized gains or losses, respectively. Gains or losses are realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). When the swap is terminated, the Trusts 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.

	Credit default swaps — Credit default swaps are agreements in which one party pays fixed periodic payments to a counterparty in consideration for a guarantee from the counterparty to make a specific payment should a negative credit event take place.

	Interest rate swaps — 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. Alternatively, a party may pay a fixed rate and receive a floating rate. Interest rate swaps are efficient as asset/liability management tools. In more complex swaps, the notional principal amount may decline (or amortize) over time.

	Total return swaps — Total return swaps are agreements in which one party commits to pay interest in exchange for a market-linked return. 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.

•	Swaptions — Swap options (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.

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.

Asset-Backed and Mortgage-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 in the secondary market certain mortgage pass-through securities. There are a number of important differences



76	ANNUAL REPORT	AUGUST 31, 2008




Notes to Financial Statements (continued)

among the agencies and instrumentalities of the U.S. 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 National Mortgage Association (“FNMA”) include 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 Schedules 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.

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.

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.

Floating Rate Loans: The 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 InterBank Offered Rate), (ii) the prime rate offered by one or more U.S. 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.

A Trust earns and/or pays facility and other fees on floating rate loans. Other fees earned/paid include commitment, amendment, consent, commissions and prepayment penalty fees. Facility, amendment and consent fees are typically amortized as premium and/or accreted as discount over the term of the loan. Commitment, commission and various other fees are recorded as income. Prepayment penalty fees are recorded on the accrual basis. When the 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 Trust 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 Trust may receive a prepayment penalty fee upon the prepayment of a floating rate loan by a borrower. Other fees received by the Trust may include covenant waiver fees and covenant modification fees.

A Trust 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 a Trust may not benefit directly from any collateral supporting the loan in which it has purchased the Participation.

As a result, a Trust will assume the credit risk of both the borrower and the lender that is selling the Participation. The Trust’s 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 Trust may be treated as general creditors of the lender and may not benefit from any offset between the lender and the borrower.

Interest Rate Floors: Interest rate floors are similar to interest rate swaps, except that one party agrees to pay a fee, while the other party pays the deficiency, if any, of a floating rate under a specified fixed or floating rate.

Interest rate floors are used by the Trusts to both manage the duration of the portfolios and their exposure to changes in short-term interest rates. The Trusts’ leverage provides extra income in a period of falling rates.



ANNUAL REPORT	AUGUST 31, 2008	77




Notes to Financial Statements (continued)

Selling floors reduces some of that extra income by partially monetizing it as an up front payment which the Trusts receive.

Transaction fees paid or received by the Trusts are recognized as assets or liabilities and amortized or accreted into interest expense or income over the life of the interest rate floor. The asset or liability is subsequently adjusted to the current market value of the interest rate floor purchased or sold. Changes in the value of the interest rate floor are recognized as unrealized gains and losses.

Mortgage Dollar Rolls: Each Trust may sell mortgage-backed securities for delivery in the current month and simultaneously contract to repurchase substantially similar (same type, coupon and maturity) securities on a specific future date at an agreed-upon price. The market value of the securities that the Trust is required to purchase may decline below the agreed upon repurchase price of those securities. Pools of mortgages collateralizing those securities may have different prepayment histories than those sold. During the period between the sale and the repurchase, the Trust will not be entitled to receive interest and principal payments on the securities sold. Proceeds of the sale will be invested in additional instruments for the Trust, and the income from these investments will generate income for the Trust.

If such income does not exceed the income, capital appreciation and gain or loss that would have been realized on the securities sold as part of the dollar roll, the use of this technique will diminish the investment performance of the Trust compared with what the performance would have been without the use of dollar rolls.

Preferred Stock: The Trusts may invest in preferred stocks. Preferred stock has a preference over common stocks 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.

Reverse Repurchase Agreements: The Trusts may enter into reverse repurchase agreements with qualified third party broker-dealers. Interest on the value of the reverse repurchase agreements issued and outstanding is based upon competitive market rates at the time of issuance. At the time the Trust enters into a reverse repurchase agreement, it identifies for segregation certain liquid securities having a value not less than the repurchase price, including accrued interest, of the reverse repurchase agreement. 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.

TBA Commitments: The Trusts may enter into to-be-announced (“TBA”) commitments to purchase or sell securities for a fixed price at a future date. TBA commitments are considered securities in themselves, and 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 Trust’s other assets. Unsettled TBA commitments are valued at the current market value of the underlying securities, according to the procedures described under “Valuation of Investments.”

Zero Coupon Bonds: The Trusts 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: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission (“SEC”) require that each Trust segregates assets in connection with certain investments (e.g., reverse repurchase agreements, swaps, swaptions or futures contracts) or certain borrowings, each Trust will, consistent with certain interpretive letters issued by the SEC, designate on their books and record cash or other liquid debt securities having a market value at least equal to the amount that would otherwise be required to be physically segregated.

Investment Transactions and Investment Income: Investment transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. 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 amortize all premiums and discounts on debt securities.

Dividends and Distributions: Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. 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 their taxable income to their 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.

Effective April 30, 2008, each Trust except High Income implemented Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes - an interpretation of FASB



78	ANNUAL REPORT	AUGUST 31, 2008




Notes to Financial Statements (continued)

Statement No. 109” (“FIN 48”). Effective June 30, 2007, High Income implemented FIN 48. FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including investment companies, before being measured and recognized in the financial statements. The investment advisor has evaluated the application of FIN 48 to the Trusts, and has determined that the adoption of FIN 48 does not have a material impact on each Trust’s financial statements. Each Trust files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on High Yield, Income Opportunity, Income Trust, Limited Duration and Strategic Bond’s U.S. federal tax returns remains open for the years ended October 31, 2005 through October 31, 2007. The statute of limitations on Core Bond’s and High Income’s U.S. federal tax returns remains open for the years ended December 31, 2005 through December 31, 2007. The statute of limitations on each Trust’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Recent Accounting Pronouncements: In September 2006, Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“FAS 157”), was issued and is effective for fiscal years beginning after November 15, 2007. Effective January 1, 2008, High Income adopted FAS 157. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The impact on the other Trusts’ financial statement disclosures, if any, is currently being assessed.

In March 2008, Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities—an amendment of FASB Statement No. 133” (“FAS 161”), was issued. FAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity’s results of operations and financial position. In September 2008, FASB Staff Position No. 133-1 and FASB Interpretation No. 45-4 (the “FSP”), “Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No. 45; and Clarification of the Effective Date of FASB Statement No. 161” was issued and is effective for fiscal years and interim periods ending after November 15, 2008. The FSP amends FASB Statement No. 133, “Accounting for Derivative Instruments and Hedging Activities,” to require disclosures by sellers of credit derivatives, including credit derivatives embedded in hybrid instruments. The FSP also clarifies the effective date of FAS 161, whereby disclosures required by FAS 161 are effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The impact on the Trusts’ financial statement disclosures, if any, is currently being assessed.

Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by each Trust’s Board, non-interested Directors or Trustees (“Independent Directors or Trustees”) may defer a portion of their annual complex-wide compensation. Deferred amounts earn an approximate return as though equivalent dollar amounts have been invested in common shares of other certain BlackRock Closed-End Funds selected by the Independent Directors or Trustees. This has approximately the same economic effect for the Independent Directors or Trustees as if the Independent Directors or Trustees 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 Trust. Each Trust may, however, elect to invest in common shares of other certain BlackRock Closed-End Funds selected by the Independent Directors or Trustees in order to match its deferred compensation obligations. Investments to cover each Trust’s deferred compensation liability are included in other assets on the Statements of Assets and Liabilities. Dividends and distributions from the BlackRock Closed-End Fund investments under the plan are included in income from affiliates on the Statements of Operations.

Other: Expenses directly related to a Trust are charged to that Trust. Other operating expenses shared by several Trusts are pro-rated among those Trusts on the basis of relative net assets or other appropriate methods.

2. Investment Advisory Agreement and Other Transactions with Affiliates:

Each Trust has entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Advisor”), an indirect, wholly owned subsidiary of BlackRock, Inc., to provide investment services for all Trusts and administration services for Core Bond, High Income, Limited Duration and Strategic Bond. Merrill Lynch & Co., Inc. and The PNC Financial Services Group, Inc. are principal owners of BlackRock, Inc.

Each Trust’s investment advisory fee paid to the Advisor is computed weekly and payable monthly based on an annual rate of 0.60% for Income Opportunity and 0.65% for Income Trust, of each Trust’s average net assets and 0.75% of the first $200 million and 0.50% thereafter for High Income, 0.55% for Core Bond and Limited Duration, 1.05% for High Yield and 0.75% for Strategic Bond, of each Trust’s average total assets (including any assets attributable to borrowings) minus the sum of accrued liabilities (other than debt representing financial leverage). The Advisor has voluntarily agreed to waive a portion of the investment advisory fees or other expenses on Strategic Bond as a percentage of its average weekly managed assets as follows: 0.15% through February 29, 2008, 0.10% through February 28, 2009 and 0.05% through February 28, 2010.

High Yield, Income Opportunity and Income Trust each has an Administration Agreement with the Advisor. The administration fee paid to the Advisor is computed weekly and payable monthly based on an annual rate, 0.10% for Income Opportunity, and 0.15% for Income Trust, of each Trust’s average net assets and 0.10% for High Yield of the Trust’s average weekly managed assets.



ANNUAL REPORT	AUGUST 31, 2008	79

5. Commitments:

Limited Duration may invest in floating rate loans. In connection with these investments, the Trust may, with its Advisor, also enter into unfunded corporate loans (“commitments”). Commitments may obligate the Trust to furnish temporary financing to a borrower until permanent financing can be arranged. At August 31, 2008, the Trust had outstanding commitments of approximately $919,000. In connection with these commitments, the Trust earns 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 August 31, 2008, the Trust had the following unfunded loan commitments:



Borrower	Unfunded Commitment (000)		Value of Underlying Loan (000)

Cellular South	$	500	$	480
Community Health Systems, Inc.		419		396

Foreign Currency Exchange Commitments: At August 31, 2008, Income Opportunity had entered into foreign exchange contracts, in addition to the contracts listed on the Schedule of Investments, under which it had agreed to sell a foreign currency with an approximate value of $280,000.

6. Capital Share Transactions:

There are 200 million of $0.01 par value shares authorized for Income Opportunity and Income Trust. There are an unlimited number of $0.001 par value shares authorized for Core Bond, High Yield, Limited Duration and Strategic Bond. There are an unlimited number of no par value shares authorized for High Income. At August 31, 2008, the shares owned by an affiliate of the Advisor of Limited Duration were 6,021.

During the period November 1, 2007 (January 1, 2008 for High Income) to August 31, 2008, shares remained constant. For the years ended October 31, 2007 and 2006, the following Trusts issued additional shares under their respective dividend reinvestment plan:



	October 31, 2007		October 31, 2006

High Yield		1,496		6,259
Limited Duration		107,367		13,785

For High Income, for the year ended December 31, 2007, shares remained constant and for the year ended December 31, 2006 shares increased by 127,532.

7. Short Term Borrowings:

On May 16, 2008, High Income and High Yield renewed their revolving credit and security agreement funded by a commercial paper asset securiti-zation program with Citicorp North America, Inc. (“Citicorp”), as Agent, certain secondary backstop lenders and certain asset securitization conduits, as lenders (the “Lenders”). The agreement was renewed for one year and has a maximum limit of $80,000,000 for High Income and $32,000,000 for High Yield. Under the Citicorp program, the conduits will fund advances to these Trusts through highly rated commercial paper. High Income and High Yield have granted a security interest in substantially all of its assets



ANNUAL REPORT	AUGUST 31, 2008	81




Notes to Financial Statements (continued)

to, and in favor of, the Lenders as security for its obligations to the Lenders. The interest rate on the Trust’s borrowings is based on the interest rate carried by the commercial paper plus a program fee. In addition, the Trusts pay a liquidity fee to the secondary backstop lenders and the agent. These amounts are included in interest expense on the Statements of Operations.

For the period ended August 31, 2008, the daily weighted average interest rates were as follows:



	Daily Weighted Average Interest Rate

High Income		2.91	%
High Yield		4.36	%

8. Income Tax Information:

Reclassification: Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or on net asset values per share. The following permanent differences as of August 31, 2008 attributable to paydowns, accounting for swap agreements, foreign currency transactions, amortization methods on fixed income securities, expiration of capital loss carryforwards and other differences between financial reporting and tax accounting, were reclassified to the following accounts:



	Core Bond			High Income			High Yield			Income Opportunity

Increase (decrease) paid-in-capital	$	(1,762,892	)	$	(35,363,213	)	$	(3,270,311	)	$	26,609

As of August 31, 2008, the tax components of accumulated earnings (losses) were as follows:



	Core Bond			High Income			High Yield			Income Opportunity

Total Accumulated Net Earnings (Losses)	$	(35,272,089	)	$	(84,949,357	)	$	(8,358,187	)

The difference between book-basis and tax-basis net unrealized gains (losses) is attributable primarily to the tax deferral of losses on wash sales, the realization for tax purposes of unrealized gains on certain options, futures and foreign currency contracts, the difference between book and tax amortization methods for premiums and discounts on fixed income securities, the deferral of compensation to trustees, accounting for swap agreements, book/tax differences in the accrual of income on securities in default and other book/tax temporary differences.

As of August 31, 2008, the Trusts had capital loss carryforwards available to offset future realized capital gains through the indicated expiration dates:

Our procedures include confirmation of the securities owned as of August 31, 2008, by correspondence with the custodian, brokers and financial intermediaries; where replies were not received from brokers and financial intermediaries, 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 Core Bond Trust, BlackRock High Yield Trust, BlackRock Income Opportunity Trust, Inc., BlackRock Income Trust, Inc., BlackRock Limited Duration Income Trust, and BlackRock Strategic Bond Trust as of August 31, 2008, the results of their operations for the period November 1, 2007 to August 31, 2008 and for the year ended October 31, 2007, the results of cash flows for the period November 1, 2007 to August 31, 2008 for BlackRock Core Bond Trust, BlackRock High Yield Trust, BlackRock Income Opportunity Trust, Inc., and BlackRock Limited Duration Income Trust, changes in their net assets for the period November 1, 2007 to August 31, 2008 and for each of the two years in the period ended October 31, 2007, and the financial highlights for the periods presented, 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 High Income Shares as of August 31, 2008, the results of its operations for the period January 1, 2008 to August 31, 2008 and for the year ended December 31, 2007, the statement of cash flows for the period January 1, 2008 to August 31, 2008, the changes in its net assets for the period January 1, 2008 to August 31, 2008 and for each of the two years in the period ended December 31, 2007, and the financial highlights for the period January 1, 2008 to August 31, 2008 and for each of the three years in the period ended December 31, 2007, in conformity with accounting principles generally accepted in the United States of America.

Disclosure of Investment Advisory Agreement and Subadvisory Agreement

The Board of Trustees (collectively, the “Board,” the members of which are referred to as “Trustees”) of the BlackRock Core Bond Trust (“BHK”), BlackRock High Income Shares (“HIS”), BlackRock High Yield Trust (“BHY”), BlackRock Income Opportunity Trust, Inc. (“BNA”), BlackRock Income Trust, Inc. (“BKT”), BlackRock Limited Duration Income Trust (“BLW”) and BlackRock Strategic Bond Trust (“BHD,” and together with BHK, HIS, BHY, BNA, BKT and BLW, the “Funds”) met in April and May 2008 to consider approving the continuation of each Fund’s investment advisory agreement (each, an “Advisory Agreement”) with BlackRock Advisors, LLC (the “Advisor”), each Fund’s investment advisor. The Board also considered the approval of each Fund’s subadvisory agreement (each, a “Subadvisory Agreement” and, together with the “Advisory Agreement,” the “Agreements”) between the Advisor and BlackRock Financial Management, Inc. (the “Subadvisor”). The Advisor and the Subadvisor are collectively referred to herein as the “Advisors” and, together with BlackRock, Inc., “BlackRock.”

Disclosure regarding HIS’s Investment Advisory Agreement and Subadvisory Agreement can be found in its most recent semi-annual report dated June 30, 2008 and is incorporated herein by reference.

Activities and Composition of the Board

The Board of each Fund consists of thirteen individuals, eleven of whom are not “interested persons” of the Funds as defined in the Investment Company Act of 1940 (the “1940 Act”) (the “Independent Trustees”). The Trustees are responsible for the oversight of the operations of the Funds and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Trustees have retained independent legal counsel to assist them in connection with their duties. The Chairman of the Board is an Independent Trustee. The Board has established four standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee and a Performance Oversight Committee.

Advisory Agreement and Subadvisory Agreement

Upon the consummation of the combination of BlackRock, Inc.’s investment management business with Merrill Lynch & Co., Inc.’s investment management business, including Merrill Lynch Investment Managers, L.P., and certain affiliates, each Fund entered into an Advisory Agreement and a Subadvisory Agreement, each with an initial two-year term. Consistent with the 1940 Act, after the Advisory Agreement’s and Subadvisory Agreement’s respective initial two-year term, the Board is required to consider the continuation of each Fund’s Advisory Agreement and Subadvisory Agreement on an annual basis. In connection with this process, the Board assessed, among other things, the nature, scope and quality of the services provided to each Fund by the personnel of BlackRock and its affiliates, including investment advisory services, administrative services, secondary market support services, oversight of fund accounting and custody, and assistance in meeting legal and regulatory requirements. The Board also received and assessed information regarding the services provided to each Fund by certain unaffiliated service providers.

Throughout the year, the Board also considered a range of information in connection with its oversight of the services provided by BlackRock and its affiliates. Among the matters the Board considered were: (a) investment performance for one-, three- and five-year periods, as applicable, against peer funds, as well as senior management and portfolio managers’ analysis of the reasons for underperformance, if applicable; (b) fees, including advisory, administration and other fees paid to BlackRock and its affiliates by each Fund, as applicable; (c) Fund operating expenses paid to third parties; (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 procedures; (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 guidelines approved by the Board; (i) execution quality; (j) valuation and liquidity procedures; and (k) reviews of BlackRock’s business, including BlackRock’s response to the increasing scale of its business.

Board Considerations in Approving the Advisory Agreement and Subadvisory Agreement

To assist the Board in its evaluation of the Agreements, the Trustees received information from BlackRock in advance of the April 22, 2008 meeting which detailed, among other things, the organization, business lines and capabilities of the Advisors, including: (a) the responsibilities of various departments and key personnel and biographical information relating to key personnel; (b) financial statements for BlackRock; (c) the advisory and/or administrative fees paid by each Fund to the Advisors, including comparisons, compiled by Lipper Inc. (“Lipper”), an independent third party, with the management fees, which include advisory and administration fees, of funds with similar investment objectives (“Peers”); (d) the profitability of BlackRock and certain industry profitability analyses for advisors to registered investment companies; (e) the expenses of BlackRock in providing various services; (f) non-investment advisory reimbursements, if applicable, and “fallout” benefits to BlackRock; (g) economies of scale, if any, generated through the Advisors’ management of all of the BlackRock closed-end funds (the “Fund Complex”); (h) the expenses of each Fund, including comparisons of each such Fund’s expense ratios (both before and after any fee waivers) with the expense ratios of its Peers; (i) an internal comparison of management fees classified by Lipper, if applicable; and (j) each Fund’s performance for the past one-, three- and five-year periods, as applicable, as well as each Fund’s performance compared to its Peers.

The Board also considered other matters it deemed important to the approval process, where applicable, such as payments made to BlackRock or its affiliates relating to the distribution of Fund shares, services related to the valuation and pricing of Fund portfolio holdings, and direct and indirect benefits to BlackRock and its affiliates from their relationship with the Funds.

In addition to the foregoing materials, independent legal counsel to the Independent Trustees provided a legal memorandum outlining, among other things, the duties of the Board under the 1940 Act, as well as the general principles of relevant law in reviewing and approving advisory contracts, the requirements of the 1940 Act in such matters, an advisor’s fiduciary duty



ANNUAL REPORT	AUGUST 31, 2008	85




Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued)

with respect to advisory agreements and compensation, and the standards used by courts in determining whether investment company boards of directors have fulfilled their duties and the factors to be considered by boards in voting on advisory agreements.

The Independent Trustees reviewed this information and discussed it with independent legal counsel prior to the meeting on April 22, 2008. At the Board meeting on April 22, 2008, BlackRock made a presentation to and responded to questions from the Board. Following the meeting on April 22, 2008, the Board presented BlackRock with questions and requests for additional information. BlackRock responded to these requests with additional written materials provided to the Trustees prior to the meetings on May 29 and 30, 2008. At the Board meetings on May 29 and 30, 2008, BlackRock responded to further questions from the Board. In connection with BlackRock’s presentations, the Board considered each Agreement and, in consultation with independent legal counsel, reviewed the factors set out in judicial decisions and Securities and Exchange Commission (“SEC”) statements relating to the renewal of the Agreements.

Matters Considered by the Board

In connection with its deliberations with respect to the Agreements, the Board considered all factors it believed relevant with respect to each Fund, including the following: the nature, extent and quality of the services provided by the Advisors; the investment performance of each Fund; the costs of the services to be provided and profits to be realized by the Advisors and their affiliates from their relationship with the Funds; the extent to which economies of scale would be realized as the Fund Complex grows; and whether BlackRock realizes other benefits from its relationship with the Funds.

A. Nature, Extent and Quality of the Services: In evaluating the nature, extent and quality of the Advisors’ services, the Board reviewed information concerning the types of services that the Advisors provide and are expected to provide to each Fund, narrative and statistical information concerning each Fund’s performance record and how such performance compares to each Fund’s Peers, information describing BlackRock’s organization and its various departments, the experience and responsibilities of key personnel and available resources. The Board noted the willingness of the personnel of BlackRock to engage in open, candid discussions with the Board. The Board further considered the quality of the Advisors’ investment process in making portfolio management decisions.

In addition to advisory services, the Trustees considered the quality of the administrative and non-investment advisory services provided to the Funds. The Advisors and their affiliates provided each Fund with such administrative and other services, as applicable (in addition to any such services provided by others for the Funds), and officers and other personnel as are necessary for the operations of the respective Fund. In addition to investment management services, the Advisors and their affiliates provided each Fund with services such as: preparing shareholder reports and communications, including annual and semi-annual financial statements and the Funds’ websites; communications with analysts to support secondary market trading; assisting with daily accounting and pricing; preparing periodic filings with regulators and stock exchanges; overseeing and coordinating the activities of other service providers; administering and organizing Board meetings and preparing the Board materials for such meetings; providing legal and compliance support (such as helping to prepare proxy statements and responding to regulatory inquiries); and performing other Fund administrative tasks necessary for the operation of the respective Fund (such as tax reporting and fulfilling regulatory filing requirements). The Board considered the Advisors’ policies and procedures for assuring compliance with applicable laws and regulations.

B. The Investment Performance of the Funds and BlackRock: As previously noted, the Board received performance information regarding each Fund and its Peers. Among other things, the Board received materials reflecting each Fund’s historic performance and each Fund’s one-, three- and five-year total returns (as applicable) relative to its Peers (including the Peers’ median performance). The Board was provided with a description of the methodology used by Lipper to select each Fund’s Peers. The Board noted that it regularly reviews the performance of each Fund throughout the year. The Board reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock, which analyzed various factors that affect Lipper rankings.

The Board noted that in general BHK, BHY and BKT performed better than their respective Peers in that their performance was at or above the median of their respective Peers in at least two of the one-, three- and five-year periods reported.

The Board noted that in general BLW performed better than its Peers in that its performance was at or above the median of its Peers in at least two of the one-year, three-year and since inception periods reported.

The Board noted that although BNA underperformed its Peers in at least two of the one-, three- and five-year periods reported, such underperformance was not greater than 10% of the median return of its Peers for any of the periods above and therefore was not considered to be material.

The Board noted that BHD performed below the median of its Peers in at least two of the one-, three- and five-year periods reported. The Board then discussed with representatives of BlackRock the reasons for BHD’s under-performance during these periods compared with its Peers. The Board noted that two of BHD’s Peers have very different investment objectives in that they invest in private placement/mezzanine companies and, when recalculating the Peer universe to exclude these two funds, BHD outperforms the median of its Peers for all periods.

For each of BNA and BHD, the Board concluded that BlackRock was committed to providing the resources necessary to assist the portfolio managers and to continue improving each Fund’s performance. Based on its review, the Board generally was satisfied with BlackRock’s efforts to manage each of the Funds.

Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued)

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: In evaluating the management fees and expenses that each Fund is expected to bear, the Board considered each Fund’s current management fee structure and each Fund’s expense ratios in absolute terms as well as relative to the fees and expense ratios of its applicable Peers. The Board, among other things, reviewed comparisons of each Fund’s gross management fees before and after any applicable reimbursements and fee waivers and total expense ratios before and after any applicable waivers with those of applicable Peers. The Board also reviewed a narrative analysis of the Peer rankings prepared by Lipper and summarized by BlackRock at the request of the Board. This summary placed the Peer rankings into context by analyzing various factors that affect these comparisons.

The Board noted that each of BHK, BKT, BLW and BHD paid contractual management fees lower than or equal to the median contractual fees paid by each Fund’s respective Peers. This comparison was made without giving effect to any expense reimbursements or fee waivers.

The Board noted that, although BHY paid contractual management fees that were higher than the median of its Peers, the Advisor had incurred substantially greater business risk in connection with the initial public offering of common shares of the Fund because the Advisor had paid the underwriting commissions on behalf of investors. The Board concluded that a higher fee to compensate the Advisor for this additional risk was reasonable.

The Board noted that, although BNA paid contractual management fees that were higher than the median of its Peers, the Fund’s actual management fees were below the median of its Peers.

The Board also compared the management fees charged and services provided by the Advisors to closed-end funds in general versus other types of clients (such as open-end investment companies and separately managed institutional accounts) in similar investment categories. The Board noted certain differences in services provided and costs incurred by the Advisor with respect to closed-end funds compared to these other types of clients and the reasons for such differences.

In connection with the Board’s consideration of the fees and expense information, the Board reviewed the considerable investment management experience of the Advisors and considered the high level of investment management, administrative and other services provided by the Advisors.

D. Profitability of BlackRock: The Board also considered BlackRock’s profitability in conjunction with its review of fees. The Board reviewed BlackRock’s profitability with respect to the Fund Complex and other fund complexes managed by the Advisors. In reviewing profitability, the Board recognized that one of the most difficult issues in determining profitability is establishing a method of allocating expenses. The Board also reviewed BlackRock’s assumptions and methodology of allocating expenses, noting the inherent limitations in allocating costs among various advisory products. The Board also recognized that individual fund or product line profitability of other advisors is generally not publicly available.

The Board recognized that profitability may be affected by numerous factors including, among other things, the types of funds managed, expense allocations and business mix, and therefore comparability of profitability is somewhat limited. Nevertheless, to the extent available, the Board considered BlackRock’s operating margin compared to the operating margin estimated by BlackRock for a leading investment management firm whose operations consist primarily of advising closed-end funds. The comparison indicated that BlackRock’s operating margin was approximately the same as the operating margin of such firm.

In evaluating the reasonableness of the Advisors’ compensation, the Board also considered any other revenues paid to the Advisors, including partial reimbursements paid to the Advisors for certain non-investment advisory services, if applicable. The Board noted that these payments were less than the Advisors’ costs for providing these services. The Board also considered indirect benefits (such as soft dollar arrangements) that the Advisors and their affiliates are expected to receive, which are attributable to their management of the Fund.

E. Economies of Scale: In reviewing each Fund’s fees and expenses, the Board examined the potential benefits of economies of scale, and whether any economies of scale should be reflected in the Fund’s fee structure, for example through the use of breakpoints for the Fund or the Fund Complex. In this regard, the Board reviewed information provided by BlackRock, noting that most closed-end fund complexes do not have fund-level breakpoints because closed-end funds generally do not experience substantial growth after their initial public offering and each fund is managed independently consistent with its own investment objectives. The Board noted that only three closed-end funds in the Fund Complex have breakpoints in their fee structures. Information provided by Lipper also revealed that only one closed-end fund complex used a complex-level breakpoint structure. The Board found, based on its review of comparable funds, that each Fund’s management fee is appropriate in light of the scale of the respective Fund.

F. Other Factors: In evaluating fees, the Board also considered indirect benefits or profits the Advisors or their affiliates may receive as a result of their relationships with the Funds (“fall-out benefits”). The Trustees, including the Independent Trustees, considered the intangible benefits that accrue to the Advisors and their affiliates by virtue of their relationships with the Funds, including potential benefits accruing to the Advisors and their affiliates as a result of participating in offerings of the Funds’ shares, potentially stronger relationships with members of the broker-dealer community, increased name recognition of the Advisors and their affiliates, enhanced sales of other investment funds and products sponsored by the Advisors and their affiliates and increased assets under management which may increase the benefits realized by the Advisors from soft dollar arrangements with broker-dealers. The Board also considered the unquantifiable nature of these potential benefits.

Conclusion with Respect to the Agreements

In reviewing and approving the continuation of the Agreements, the Trustees did not identify any single factor discussed above as all-important or controlling, but considered all factors together, and different Trustees may have attributed different weights to the various factors considered. The Independent Directors were also assisted by the advice of independent legal counsel in making this determination. The Trustees, including the Independent Trustees, unanimously determined that each of the factors described above, in light of all the other factors and all of the facts and circumstances applicable to each respective Fund, was acceptable for each Fund and supported the Trustees’ conclusion that the terms of each Agreement were fair and reasonable, that each Fund’s fees are reasonable in light of the services provided to the respective Fund and that each Agreement should be approved.

Dividend Reinvestment Plans

Pursuant to each Trust’s respective Dividend Reinvestment Plan (the “Plan”), common shareholders of High Income, Income Opportunity and Income Trust may elect, while shareholders of Core Bond, High Yield, Limited Duration and Strategic Bond are automatically enrolled, to have all distributions of dividends and capital gains reinvested by Computershare Trust Company, N.A. (the “Plan Agent”) in the respective Trust’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 Core Bond, High Income, High Yield, Income Trust, Limited Duration and Strategic Bond declares a dividend or determines to make a capital gain distribution, the Plan Agent will acquire shares for the participants’ account, depending upon the circumstances described below, either (i) through receipt of unissued but authorized shares from the Trust (“newly issued shares”) or (ii) by 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 condition being referred to herein as “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 being referred to herein as “market discount”), the Plan Agent will invest the dividend amount in shares acquired on behalf of the participants in open-market purchases.

The Plan Agent’s fees for the handling of the reinvestment of dividends and distributions will be paid by each Trust. 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 Trust reserves the right to amend or terminate the Plan. There is no direct service charge to participants in the Plan; however, each Trust reserves the right to amend the Plan to include a service charge payable by the participants. Participants who request a sale of shares through the Plan Agent are subject to a $2.50 sales fee and a $0.15 per share sold brokerage commission. All correspondence concerning the Plan should be directed to the Plan Agent at P.O. Box 43078, Providence, RI 02940-3078 or by calling (800) 699-1BFM. All overnight correspondence should be directed to the Plan Agent at 250 Royall Street, Canton, MA 02021.

Additional Information

Fund Certification

The Trusts 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. Each Trust filed with the SEC the certification of their chief executive officer and chief financial officer required by section 302 of the Sabanes-Oxley Act.

Availability of Quarterly Schedule of Investments

Each Trust files their complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. Each Trust’s 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 (800) SEC-0330. Each Trust’s Forms N-Q may also be obtained upon request and without charge by calling (800) 441-7762.

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 and prospectuses 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.

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 Statements of Additional Information of the Trusts have not been updated after completion of the Trusts’ offering and the information contained in the Trusts’ Statements 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’ charters or by-laws that were not approved by the shareholders or in the principal risk factors associated with the investment in the Trusts. There have been no changes in the persons who are primarily responsible for the day-to-day management of the Trusts’ portfolios. 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 it is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your household, please contact the Trusts at (800) 441-7762

Quarterly performance, semi-annual and annual reports and other information regarding each Trust 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 each Trust and does not, and is not intended to, incorporate BlackRock’s website into this report.

Frank J. Fabozzi

Karen P. Robards

Prof. Kester has been involved in providing valuation and other financial consulting services to corporate clients since 1978.

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.

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.

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 for all of the registrants the Committee oversees. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to one or more of its members the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.

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

(f) Not Applicable

(g) Affiliates’ Aggregate Non-Audit Fees:


	Current Fiscal Year	Previous Fiscal Year
Entity Name	End	End

BlackRock Core Bond Trust	$288,549	$291,642

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

Regulation S-X Rule 2-01(c)(7)(ii) – $287,500, 0%

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

Item 6 – Investments

(a) The registrant’s Schedule of Investments is included as part of the Report to Stockholders filed under Item 1 of this form.

(b) Not Applicable due to no such divestments during the semi-annual period covered since the previous Form N-CSR filing.

Item 7 – Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies – The board of directors has delegated the voting of proxies for the Fund securities to the Fund’s investment advisor (“Investment Advisor”) pursuant to the Investment Advisor’s proxy voting guidelines. Under these guidelines, the Investment Advisor 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 Advisor, or any affiliated person of the Fund or the Investment Advisor, on the other. In such event, provided that the Investment Advisor’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 Advisor’s clients. If the Investment Advisor 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 Advisor’s Portfolio Management Group and/or the Investment Advisor’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.

(iv) Potential Material Conflicts of Interest

BlackRock, Inc. 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 for the Fund. In addition, BlackRock, its affiliates and any officer, director, stockholder or employee may or may not have an interest in the securities whose purchase and sale BlackRock recommends to the Fund. BlackRock, or any of its affiliates, or any officer, director, stockholder, employee or any member of their families may take different actions than those recommended to the Fund by BlackRock with respect to the same securities. Moreover, BlackRock may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock’s (or its affiliates’) officers, directors or employees are directors or officers, or companies as to which BlackRock or any of its affiliates or the officers, directors or 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 regard, it should be noted that Messrs. Spodek, Booth and Keenan currently manage certain accounts that are subject to performance fees. In addition, Messrs. Spodek and Keenan assist in managing certain hedge funds and may be entitled to receive a portion of any incentive fees earned on such funds and a portion of such incentive fees may be voluntarily or involuntarily deferred. Additional portfolio managers may in the future manage other such accounts or funds and may be entitled to receive incentive fees.

As a fiduciary, BlackRock owes a duty of loyalty to its clients and must treat each client fairly. When BlackRock purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. BlackRock attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock has adopted a policy that is intended to ensure that investment opportunities are allocated fairly and equitably among client accounts over time. This policy also seeks to achieve reasonable efficiency in client transactions and provide BlackRock with sufficient flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base.

(a)(3) As of August 31, 2008:

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 for the Fund include the following:

	Portfolio Manager	Benchmarks Applicable to Each Manager
	Stuart Spodek	A combination of market-based indices (e.g., Citigroup 1-Year
		Treasury Index, Merrill Lynch 1-3 Year Treasury Index,
		Lehman Brothers Global Real: U.S. Tips Index), certain
		customized indices and certain fund industry peer groups.
	Kevin Booth	A combination of market-based indices (e.g., The Lehman
		Brothers U.S. Corporate High Yield 2% Issuer Cap Index),
		certain customized indices and certain fund industry peer
		groups.
	James Keenan	A combination of market-based indices (e.g., The Lehman
		Brothers U.S. Corporate High Yield 2% Issuer Cap Index),
		certain customized indices and certain fund industry peer
		groups.

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

Distribution of Discretionary Incentive Compensation

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

Long-Term Retention and Incentive Plan (“LTIP”) — The LTIP is a long-term incentive plan that seeks to reward certain key employees. Prior to 2006, the plan provided for the grant of awards that were expressed as an amount of cash that, if properly vested and subject to the attainment of certain performance goals, will be settled in cash and/or in BlackRock, Inc. common stock. Beginning in 2006, awards are granted under the LTIP in the form of BlackRock, Inc. restricted stock units that, if properly vested and subject to the attainment of certain performance goals, will be settled in BlackRock, Inc. common stock. Messrs. Spodek, Booth and Keenan 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. Spodek, Booth and Keenan have each participated in the deferred compensation program.

Options and Restricted Stock Awards — A portion of the annual compensation of certain employees is mandatorily deferred into BlackRock restricted stock units. Prior to the mandatory deferral into restricted stock units, BlackRock granted stock options to key employees, including certain portfolio managers who may still hold unexercised or unvested options. BlackRock, Inc. also granted restricted stock awards designed to reward certain key employees as an incentive to contribute to the long-term success of BlackRock. These awards vest over a period of years. Mr. Spodek has been granted stock options and/or restricted stock in prior years.

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% of eligible compensation, plus an additional contribution of 2% for any year in which BlackRock has positive net operating income. 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.
