A Letter to Shareholders

Dear Shareholder

Financial markets endured a heightened volatility during 2007, culminating in mixed results for some of the major benchmark indexes:

Total Returns as of December 31, 2007

	6-month		12-month
U.S. equities (S&P 500 Index)	–1.37	%	+5.49	%
Small cap U.S. equities (Russell 2000 Index)	–7.53		–1.57
International equities (MSCI Europe, Australasia, Far East Index)	+0.39		+11.17
Fixed income (Lehman Brothers U.S. Aggregate Bond Index)	+5.93		+6.97
Tax-exempt fixed income (Lehman Brothers Municipal Bond Index)	+3.22		+3.36
High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index)	–0.67		+2.27

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

Subprime mortgage woes dominated headlines for much of 2007, spawning a widespread liquidity and credit crisis with ramifications across global markets. The Federal Reserve Board (the “Fed”) stepped in to inject liquidity into the markets and bolster investor confidence, cutting the federal funds rate by 0.50% in September, 0.25% in October and 0.25% in December, which brought the target short-term interest rate to 4.25%. In taking action, the central bankers, who had long deemed themselves inflation fighters, were seeking to stem the fallout from the credit crunch and forestall a wider economic unraveling.

Amid the volatility, equity markets displayed surprising resilience. Market fundamentals generally held firm, dividend payouts and share buybacks continued, and valuations remained attractive. To some extent, the credit turmoil dampened corporate merger-and-acquisition (M&A) activity, a key source of strength for equity markets, but 2007 remained a record year for global M&A nonetheless. As the returns indicate, the most recent six months were more trying, reflecting the slowing U.S. economy, a troubled housing market and a more difficult corporate earnings backdrop. Overall, large cap stocks outperformed small caps as investors grew increasingly risk averse. International markets fared better than their U.S. counterparts, benefiting from generally stronger economies.

In fixed income markets, mixed economic signals and subprime fallout resulted in a flight to quality. Investors shunned bonds associated with the housing and credit markets in favor of higher-quality Treasury issues. The yield on 10-year Treasury issues, which touched 5.30% in June (its highest level in five years), fell to 4.04% by year-end, while prices correspondingly rose. The tax-exempt bond market waffled amid the economic uncertainty and concerns around the credit worthiness of bond insurers, but set a new-issuance record in 2007. A drop in municipal bond prices created buying opportunities, and the heightened supply was generally well absorbed.

As you navigate the uncertainties inherent in the financial markets, we encourage you to start the year by reviewing your investment goals with your financial professional and making portfolio changes, as needed. For more reflection on 2007 and our 10 predictions for 2008, please ask your financial professional for a copy of “What’s Ahead in 2008: An Investment Perspective,” or view it online at www.blackrock.com/funds. As always, we thank you for entrusting BlackRock with your investment assets, and we look forward to continuing to serve you in the new year and beyond.

Sincerely,

Rob Kapito

President, BlackRock Advisors, LLC

Notes to Financial Statements

1. Significant Accounting Policies:

BlackRock High Income Shares (“High Income”), a Massachusetts business trust, is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). BlackRock Global Floating Rate Income Trust (“Global”) and BlackRock Preferred Opportunity Trust (“Preferred Opportunity”) are organized as Delaware statutory trusts and are registered as non-diversified and diversified, respectively, closed-end management investment companies under the 1940 Act. Global, High Income and Preferred Opportunity are individually referred to as a “Trust” and collectively as the “Trusts”. The Trusts’ financial statements are prepared in conformity with accounting prin ciples generally accepted in the United States of America.

The following is a summary of significant accounting policies followed by the Trusts.

Valuation of Investments: The Trusts value most of their investments on the basis of last available bid price or current market quotations provided by dealers or pricing services selected under the supervision of each Trust’s Board of Trustees (the “Trustees” or a “Board”). In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, 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. Trust preferred securities are valued at the evaluated bid price. Options purchased are valued at the last bid price in the case of options traded in the OTC market. Swap quotations are provided by dealers selected under supervision of the Board. Financial futures contracts are traded on exchanges and are valued at their last sale price. Short-term securities may be valued at amortized cost.

Bank loans (“loan interests”) are valued in accordance with guidelines established by the Board. Loan interests are valued at the average between the last available bid prices from one or more brokers or dealers, as obtained from Loan Pricing Corporation (“LPC”). If no reliable price quotes are available, LPC values such interests through the use of pricing matrixes. If the pricing service does not provide a value for the loan interests, BlackRock Advisors, LLC (the “Advisor”), an indirect, wholly owned subsidiary of BlackRock, Inc., will value the loan interests at fair value under methods approved by the Trust’s Board.

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, under the direction of, or in accordance with, 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 shall seek to determine the price that the Trusts might reasonably expect to receive from the current sale of that asset in an arms-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 shall be subsequently reported to the Board or a committee thereof.

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

In addition, in February 2007, Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“FAS 159”), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. The impact on the Trusts’ financial statement disclosures, if any, is currently being assessed.

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

• Options: The Trusts may purchase call and put options. 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 Trust enters into a closing transaction), the Trust realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Purchased options are non-income producing investments.

• Credit Default Swaps: Credit default swaps are agreements in which one party pays fixed periodic payments to a counterparty for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a “guarantor” receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Trust may enter into credit default swaps in which either it or its counterparty act as guarantors. By acting as the guarantor of a swap, a fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value.

During the term of the swap, changes in the value of the swap are recognized as unrealized gains or losses by “marking-to-market” to reflect the market value of the swap. When the swap is terminated, a Trust will record

26 ANNUAL REPORT DECEMBER 31, 2007

Notes to Financial Statements (continued)

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.

The Trusts are exposed to credit loss in the event of non-performance by the other party to the swap. However, the Trusts closely monitor swaps and do not anticipate non-performance by any counterparty.

•

Financial Futures Contracts: The Trusts may purchase or sell financial futures contracts and options on such financial futures contracts. Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Trusts deposit and maintain as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Trusts agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recognized by the Trusts as unrealized gains or losses. When the contract is closed, the Trusts record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

The Trusts may utilize futures for the purpose of reducing the interest rate sensitivity of the portfolio and decreasing the Trusts’ exposure to interest rate risk.

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 Trusts have determined the ex-dividend date. Interest income is recognized on the accrual basis. The Trusts amortize all premiums and discounts on debt securities.

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 and is included within the related liability on the Statements of Assets and Liabilities. At the time the Trusts enter 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.

Loan Payable: High Income has an $80 million revolving credit agreement (the “Agreement”), which expires on March 15, 2008. Prior to expiration of the Agreement, principal is repayable in whole or in part at the option of the Trust. Borrowings under the Agreement bear interest at a variable rate tied to the lender’s average daily cost of funds, or at fixed rates, as may be agreed to between the Trust and the lender. The Trust may borrow up to 33¹/₃% of its total assets up to the committed amount or 100% of the borrowing base eligible assets, as determined under the terms of the Agreement. In accordance with the terms of the Agreement, the Trust has granted a security interest in certain portfolio assets as collateral for the borrowing. The Trust plans to renew the Agreement before expiration.

Bank Loans: In the process of buying, selling and holding bank loans, a Trust may receive and/or pay certain fees. These fees are included in the purchase price and may include facility fees, commitment fees, amendment fees, commissions and prepayment penalty fees. These fees are amortized as premium and/or accreted as discount over the term of the loan. When a Trust buys a bank loan it may receive a facility fee and when it sells a bank loan it may pay a facility fee. On an ongoing basis, a Trust may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a bank loan. In certain circumstances, a Trust may receive a prepayment penalty fee upon the prepayment of a bank loan by a borrower. Other fees received by a Trust may include covenant waiver fees and covenant modification fees.

A Trust may invest in multiple series or tranches of an issuer. A different series or tranche may have varying terms and carry different associated risks.

Forward Currency Contracts: The Trusts enter into forward currency contracts primarily to facilitate settlement of purchases and sales of foreign securities and to help manage the overall exposure to foreign currency. A forward contract is a commitment to purchase or sell a foreign currency at a future date (usually the security transaction settlement date) at a negotiated forward rate. In the event that a security fails to settle within the normal settlement period, the forward currency contract is renegotiated at a new rate. The gain or loss arising from the difference between the settlement value of the original and renegotiated forward contracts is isolated and is included in net realized gains (losses) from foreign currency transactions. Risks may arise as a result of the potential inability of the counterparties to meet the terms of their contract.

Forward currency contracts, when used by the Trusts, help to manage the overall exposure to the foreign currency backing in some of the investments held by the Trusts. Forward currency contracts are not meant to be used to eliminate all of the exposure to the foreign currency, rather they allow the Trusts to limit their exposure to the foreign currency and, in doing so, better help the Trusts achieve their objectives.

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. For equity income securities, the Trusts do not isolate the portion of the results of operations arising as a result of changes in the foreign exchange rates from the fluctuations arising from changes in the market prices of securities held at period end and sold during the period. For fixed income securities, the Trusts isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the fluctuations arising from changes in the market prices of securities held at period end. Similarly, the Trusts isolate the effect of changes in foreign exchange rates from the fluc-

ANNUAL REPORT DECEMBER 31, 2007 27

Notes to Financial Statements (continued)

tuations arising from changes in the market prices of portfolio securities sold during the period.

Short sales: When the Trusts engage in a short sale, an amount equal to the proceeds 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 market value of the short sale. The Trusts maintain a segregated account of securities as collateral for the short sales. The Trusts are exposed to market risk based on the amount, if any, that the market value of the stock exceeds the market value of the securities in the segregated account. The Trusts are required to repay the counterparty any dividends or interest received on the security sold short.

A gain, limited to the price at which the Trusts sold the security short, or a loss, unlimited as to the dollar amount, will be recognized upon the termination of a short sale if the market price is greater or less than the proceeds originally received.

Trust Preferred Stock: 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.

Credit Risk: Preferred Opportunity invests a significant portion of its assets in securities issued by financial institutions that may have exposure to commercial or residential mortgage loans and/or securities of issuers that hold mortgage and other asset-backed securities. Changes in economic conditions, including delinquencies and/or defaults of these loans and other underlying securities held by these financial institutions, may affect the value, income and/or liquidity of Preferred Opportunity’s investments. Please see the Schedule of Investments for these securities.

Segregation: In cases in which the 1940 Act, and the interpretive positions of the Securities and Exchange Commission (the “SEC”) require that each Trust segregate assets in connection with certain investments (e.g., when issued securities, reverse repurchase agreements, swaps or futures contracts), each Trust will, consistent with certain interpretive letters issued by the SEC, designate on its books and records 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.

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

Effective June 29, 2007, the Trusts implemented Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109” (“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. Management 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 the Trusts’ financial statements. The Trusts file U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Trusts’ U.S. federal tax returns remains open for the years ended December 31, 2004 through December 31, 2006. The statute of limitations on the Trust’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Dividends and Distributions: Dividends to common shareholders from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. Dividends and distributions to preferred shareholders are accrued and determined as described in Note 5. 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. For the year ended December 31, 2007, a portion of the dividends and distributions were characterized as a tax return of capital.

Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities including investment valuations at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and such differences may be material.

Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by each Trust’s Board, non-interested Trustees/Directors (“Independent Trustees”) defer a portion of their annual complex-wide compensation. Deferred amounts earn an approximate return as though equivalent dollar amounts had been invested in common shares of other BlackRock Closed-End Funds selected by the Independent Trustees. These amounts are shown on the Statement of Assets and Liabilities as “Investments in Affiliates”. This has approximately the same economic effect for the Independent Trustees as if the Independent Trustees had invested the deferred amounts directly in such Trusts.

The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of the Trust. Each Trust may, however, elect to invest in common shares of those Trusts

28 ANNUAL REPORT DECEMBER 31, 2007

Notes to Financial Statements (continued)

selected by the Independent Trustees in order to match its deferred compensation obligations.

Other: Expenses that are directly related to one of the Trusts are charged directly to that Trust. Other operating expenses are generally prorated to the Trusts on the basis of relative net assets of all the BlackRock Closed-End Funds.

2. Investment Advisory Agreement and Other Transactions with Affiliates:

Each Trust has an Investment Advisory Agreement (“the Agreements”) with the Advisor. BlackRock Financial Management, Inc. (“BFM”), a wholly owned subsidiary of BlackRock, Inc., serves as sub-advisor to the Trusts. Merrill Lynch & Co., Inc. (“Merrill Lynch”) and The PNC Financial Services Group, Inc. are principal owners of BlackRock, Inc. The Agreements for the Trusts cover both investment advisory and administration services.

The investment advisory fee paid to the Advisor is computed weekly and payable monthly based on an annual rate equal to 0.75% of Global’s and 0.65% of Preferred Opportunity’s average weekly managed assets. “Managed assets” means the total assets of a Trust (including any assets attributable to any borrowing that may be outstanding) minus the sum of accrued liabilities (other than debt representing financial leverage). The investment advisory fee paid to the Advisor is computed weekly and payable monthly based on an annual rate equal to 0.75% of the first $200 million of High Income’s average weekly managed assets and 0.50% thereafter. The Advisor has voluntarily agreed to waive a portion of the investment advisory fees or other expenses on Global as a percentage of its average weekly managed assets as follows: 0.20% for the first five years of the Trust’s operations (through August 30, 2009), 0.15% in year six (through August 30, 2010), 0.10% in year seven (through August 30, 2011) and 0.05% in year eight (through August 30, 2012).

The Advisor pays BFM fees for its sub-advisory services.

Pursuant to the Investment Management Agreements, the Advisor provides continuous supervision of each Trust’s investment portfolio and pays the compensation of officers of each Trust who are affiliated persons of the Advisor, as well as occupancy and certain clerical and accounting costs of each Trust. Each Trust bears all other costs and expenses, which include reimbursements to the Advisor for employee costs related to pricing and secondary market support. These expenses are generally pro-rated to the Trusts on the basis of the relative net assets of certain BlackRock Closed-End Funds. For the year ended December 31, 2007, the Trusts reimbursed the Advisor in the following amounts, which are included in miscellaneous expenses in the Statements of Operations:

Trust	Amount
Global		$  23,362
High Income		6,766
Preferred Opportunity		21,589

Pursuant to the terms of the custody agreements, each Trust may receive earnings credits from its custodian for positive cash balances maintained, which are used to offset custody fees. These credits are shown on the Statements of Operations as “fees paid indirectly”.

Merrill Lynch, through its affiliated broker dealer Merrill Lynch, Pierce, Fenner & Smith Incorporated, earned $41,662 in commissions on the execution of portfolio security transactions from Preferred Opportunity for the year ended December 31, 2007.

Certain officers and/or directors of the Trusts are officers and/or directors of BlackRock, Inc. or its affiliates.

4. Income Tax Information:

It is each Trust’s policy to comply with requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required.

Dividends from net investment income and distributions from net capital gains are determined in accordance with U.S. federal income tax regulations, which may differ from those amounts determined under accounting principles generally accepted in the United States. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, they are charged or credited to paid-in-capital, undistributed net investment income, or accumulated net realized gain, as appropriate, in the period the difference arise.

Reclassification of Capital Accounts: 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. Accordingly, the table below summarizes the amounts reclassified per Trust during the current year between undistributed (distributions in excess of) net investment income, accumulated net realized gain/(loss) and paid-in capital in excess of par as a result of permanent differences attributable to amortization methods of premiums and discounts on fixed income securities, accounting for swap agreements, transactions involving foreign securities and currencies, expiration of capital loss carryfor-wards and other differences between financial reporting and tax accounting were classified to the following accounts. These reclassifications have no effect on net assets or net asset values per share.

Trust	Undistributed Net Investment Income/ Distributions in Excess of Net Investment Income				Accumulated Net Realized Gain/(Loss)				Paid-In Capital in Excess of Par
Global		$	(7,272,230	)		$	7,272,230			$	—
High Income			832,748				23,305,589				(24,138,337	)
Preferred Opportunity			4,822				(4,822	)			—

The tax character of distributions paid during the year ended December 31, 2007 and 2006 were as follows:

	December 31, 2007
Distributions Paid From:	Ordinary Income		Non-taxable Return of Capital		Long-Term Capital Gains			Total Distributions
Global	$	39,557,202	$	8,473,282		$	—		$	48,030,484
High Income		12,923,299		—			—			12,923,299
Preferred Opportunity		40,678,314		2,820,986			400,000			43,899,300

	December 31, 2006
Distributions Paid From:	Ordinary Income		Long-Term Capital Gains			Total Distributions
Global	$	45,130,597		$	640,846		$	45,771,443
High Income		12,792,689			—			12,792,689
Preferred Opportunity		42,381,795			4,836,485			47,218,280

As of December 31, 2007, the components of distributable earnings on a tax basis were as follows:

Trust	Undistributed Ordinary Income		Unrealized Net Losses
Global	$	—	$	(17,200,344	)
High Income		469,701		(12,299,388	)
Preferred Opportunity		—		(54,038,067	)

The difference between book-basis and tax-basis unrealized gains/losses is attributable primarily to amortization methods of premiums and discounts on fixed income securities, the deferral of post-October capital losses for tax purposes, the tax deferral of losses on wash sales, accounting for swap agreements, the realization for tax purposes of unrealized gains/losses on certain future and foreign currency contracts, book/tax differences in the accrual of income on securities in default, the realization for tax purposes of unrealized gains on investments in passive foreign investment companies, deferred compensation to trustees and other temporary differences.

For federal income tax purposes, the following Trusts had capital loss carry-forwards at December 31, 2007. These amounts may be used to offset future realized capital gains, if any:

Trust	Capital Loss Carryforward Amount		Expires
Global	$	3,268,804		2015
High Income	$	35,363,213		2008
		55,878,284		2009
		102,576,339		2010
		28,467,396		2011
		2,339,279		2012
		7,043,976		2014
	$	231,668,487
Preferred Opportunity	$	18,184,893		2015

5. Capital:

There are an unlimited number of $0.001 par value common shares authorized for Global and Preferred Opportunity. There are an unlimited number of no par value shares authorized for High Income. At December 31, 2007, the shares owned by affiliates of the Advisor of Global were 7,551.

During the year ended December 31, 2007 and 2006, the Trusts issued the following additional shares under their respective dividend reinvestment plans:

Trust	December 31, 2007	December 31, 2006
Global	42,574	21,644
High Income	—	127,532
Preferred Opportunity	30,981	49,079

As of December 31, 2007, Global and Preferred Opportunity have the following series of Auction Preferred Shares outstanding as listed in the table below. The Auction Preferred Shares have a liquidation value of $25,000 per share plus any accumulated unpaid dividends.

Trust	Series	Shares	Trust		Series		Shares
Global	T7	3,246		Preferred		T7		2,944
	W7	3,246		Opportunity		W7		2,944
	R7	3,246				R7		2,944

ANNUAL REPORT DECEMBER 31, 2007 31

Notes to Financial Statements (concluded)

Dividends on seven-day Auction Preferred Shares are cumulative at a rate which is reset every seven days based on the results of an auction. If the Auction Preferred Shares are unable to be remarketed on the remarketing date as part of the auction process, the Trusts would be required to pay the maximum applicable rate on the Auction Preferred Shares to holders of such shares for successive dividend periods until such time as the shares are successfully remarketed. The maximum applicable rate on Auction Preferred Shares for Global is the higher of 125% of the 7-day Telerate/BBA LIBOR rate or 125% over the 7-day Telerate/BBA LIBOR rate and for Preferred Opportunity is 150% of the Interest Equivalent of the 30-day commercial paper rate. During the year ended December 31, 2007, Auction Preferred Shares of the Trusts were successfully remarketed at each remarketing date. The dividend ranges on the Auction Preferred Shares for Global and Preferred Opportunity for the year ended December 31, 2007 were as follows:

Trust	Series		Low		High		Average
Global		T7	4.15	%	6.75	%	5.16	%
		W7	4.75		6.45		5.16
		R7	4.80		6.40		5.16
Preferred Opportunity		T7	4.80		6.30		5.19
		W7	4.80		6.40		5.18
		R7	4.88		6.25		5.21

Global and Preferred Opportunity may not declare dividends or make other distributions on common shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding Auction Preferred Shares and any other borrowings would be less than 200%.

The Auction Preferred Shares are redeemable at the option of Global and Preferred Opportunity, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends whether or not declared. The Auction Preferred Shares are also subject to mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of Global and Preferred Opportunity, as set forth in Global’s and Preferred Opportunity’s Declaration of Trust, are not satisfied.

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

6. Subsequent Events:

During the period February 13, 2008 to February 29, 2008, the Auction Preferred Shares of each Trust were not successfully remarketed. As a result, the Auction Preferred Share dividend rates were reset to the maximum applicable rate which ranged from 4.37% to 4.65% for the Trusts during the period. Unsuccessful remarketing during the auction process is not an event of default or credit but rather a liquidity event for the holders of the Auction Preferred Shares.

Each Trust paid a monthly distribution to holders of Common Shares on February 29, 2008 to shareholders of record on February 15, 2008. The per share amounts were as follows:

Trust	Common Dividend Per Share
Global	$	0.1250
High Income		0.0182
Preferred Opportunity		0.1250

The dividends declared on Auction Preferred Shares for the period January 1, 2008 to January 31, 2008 for Global and Preferred Opportunity were as follows:

Trust	Series		Dividends Declared		Trust		Series		Dividends Declared
Global		T7	$	277,565		Preferred		T7	$	263,252
		W7		358,196		Opportunity		W7		327,491
		R7		354,268				R7		322,221

Report of Independent Registered Public Accounting Firm

To the Directors/Trustees and Shareholders of
	BlackRock Global Floating Rate Income Trust
	BlackRock High Income Shares
	BlackRock Preferred Opportunity Trust
	(collectively the “Trusts”):

We have audited the accompanying statements of assets and liabilities of the Trusts, including the portfolios of investments, as of December 31, 2007, and the related statements of operations and cash flows (for BlackRock High Income Shares) for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented. These financial statements and financial highlights are the responsibility of the Trusts’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The Financial Highlights of BlackRock High Income Shares for each of the two years in the period ended December 31, 2004 were audited by other auditors whose report, dated February 22, 2005, expressed an unqualified opinion on the financial highlights.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trusts are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trusts’ internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, 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 the Trusts as of December 31, 2007, the results of their operations and cash flows (for BlackRock High Income Shares) for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.

The Benefits and Risks of Leveraging (unaudited)

The Trusts may utilize leveraging through borrowings or issuance of short-term debt securities or shares of Auction Preferred Stock. 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 on borrowings or dividend rates on the Auction Preferred Stock, 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 Common Stock shareholders will be the beneficiaries of the incremental yield.

As of December 31, 2007, the Trusts had the following leverage amounts to total net assets before the deduction of leverage of:

Trust	Leverage
Global		37%
High Income		25%
Preferred Opportunity		38%

Leverage creates risks for holders of Common Stock including the likelihood of greater net asset value and market price volatility. In addition, there is the risk that fluctuations in interest rates on borrowings or in the dividend rates on any Auction Preferred Stock may reduce the Common Stock’s yield and negatively impact its net asset value and market price. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, each Trust’s net income will be greater than if leverage had not been used. Conversely, if the income from the securities purchased is not sufficient to cover the cost of leverage, each Trust’s net income will be less than if leverage had not been used, and therefore the amount available for distribution to Common Stock shareholders will be reduced.

34 ANNUAL REPORT DECEMBER 31, 2007

Dividend Reinvestment Plans (unaudited)

Pursuant to each Trust’s respective Dividend Reinvestment Plan (the “Plan”), shareholders of High Income may elect, while shareholders of Global and Preferred Opportunity 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 each Trust declares a dividend or determines to make a capital gain distribution, the Plan Agent will acquire shares for the participant’s 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 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.

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

The Plan Agent’s fees for the handling of the reinvestment of dividends and distributions is paid by each Trust. However, each participant pays 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 does 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 250 Royall Street, Canton, MA 02021 or (800) 699-1BFM.

Other Information

From time to time in the future, the Trusts may effect redemptions and/or repurchases of its Auction Preferred Shares as provided in the applicable constituent instruments or as agreed upon by the Trust and holders of Auction Preferred Shares. The Trusts would generally effect such redemptions and/or repurchases to the extent necessary to maintain applicable asset coverage requirements.

¹ Voted on by holders of Auction Preferred Shares only for Global and Preferred Opportunity.

Each Trust listed for trading on the New York Stock Exchange (“NYSE”) has filed with the NYSE its chief executive officer certification regarding compliance with the NYSE’s listing standards and have filed with the Securities and Exchange Commission the certification of its chief executive officer and chief financial officer required by section 302 of the Sarbanes-Oxley Act.

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

During the period, there were no material changes in any Trust’s investment objective or policies or to any Trust’s charters or by-laws that were not approved by the shareholders or in the principal risk factors associated with 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’ portfolio.

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

Section 19 Notices (unaudited)

The amounts and sources of distributions reported are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon the Trust’s investment experience during the remainder of its fiscal year and may be subject to changes based on the tax regulations. The Trust will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

	Total Fiscal Year to Date Cumulative Distributions by Character								Percentage of Fiscal Year to Date Cumulative Distributions by Character
Trust	Net Investment Income		Net Realized Capital Gains		Return of Capital		Total Per Common Share		Net Investment Income		Net Realized Capital Gains		Return of Capital		Total Per Common Share
Preferred Opportunity	$	1.34	$	—	$	0.30	$	1.64	82	%	0	%	18	%	100	%

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

The Trusts will mail only one copy of shareholder documents, including annual and semi-annual reports and proxy statements, to shareholders with multiple accounts at the same address. This practice is commonly called “householding” and is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your household, please contact the Trusts at (800) 699-1BFM.

A description of the policies and procedures that the Trusts use to determine how to vote proxies relating to portfolio securities is available (1) without charge, upon request, by calling toll-free 1-(800)-699-1BFM; (2) at www.blackrock.com; and (3) on the Securities and Exchange Commission’s Web site at http://www.sec.gov.

The Trusts file their complete schedules of portfolio holdings with the Securities and Exchange Commission (“SEC”) for the first and third quarters of each fiscal year on Form N-Q. The Trusts’ Forms N-Q are available on the SEC’s Web site at http://www.sec.gov. The Trusts’ Forms N-Q may also be reviewed and copied at the SEC’s Public Reference Room in Washington, DC.

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

Item 3 – Audit Committee Financial Expert – The registrant's board of directors or trustees, as applicable (the “board of directors”) has determined that (i) the registrant has the following audit committee financial experts serving on its audit committee and (ii) each audit committee financial expert is independent:
Kent Dixon
Frank J. Fabozzi
Robert S. Salomon, Jr. (term began effective November 1, 2007)
W. Carl Kester (term began effective November 1, 2007)
James T. Flynn (term began effective November 1, 2007)
Karen P. Robards (term began effective November 1, 2007)

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

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

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

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

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 has polices and procedures (the "Policy") for the pre-approval by the registrant's audit committee of Audit, Audit-Related, Tax and Other Services (as each is defined in the Policy) provided by the Fund's independent auditor (the "Independent Auditor") to the registrant and other "Covered Entities" (as defined below). The term of any such pre-approval is 12 months from the date of pre-approval, unless the audit committee specifically provides for a different period. The amount of any such pre-approval is set forth in the appendices to the Policy (the "Service Pre-Approval Documents"). At its first meeting of each calendar year, the audit committee will review and re-approve the Policy and approve or re-approve the Service Pre-Approval Documents for that year, together with any changes deemed necessary or desirable by the audit committee. The audit committee may, from time to time, modify the nature of the services pre-approved, the aggregate level of fees pre-approved or both.

     For the purposes of the Policy, "Covered Services" means (A) all engagements for audit and non-audit services to be provided by the Independent Auditor to the Fund and (B) all engagements for non-audit services related directly to the operations and financial reporting or the Fund to be provided by the Independent Auditor to any Covered Entity, "Covered Entities" means (1) the Advisor or (2) any entity controlling, controlled by or under common control with the Advisor that provides ongoing services to the Fund.

     In the intervals between the scheduled meetings of the audit committee, the audit committee delegates pre-approval authority under this Policy to the Chairman of the audit committee (the "Chairman"). The Chairman shall report any pre-approval decisions under this Policy to the audit committee at its next scheduled meeting. At each scheduled meeting, the audit committee will review with the Independent Auditor the Covered Services pre-approved by the Chairman pursuant to delegated authority, if any, and the fees related thereto. Based on these reviews, the audit committee can modify, at its discretion, the pre-approval originally granted by the Chairman pursuant to delegated authority. This modification can be to the nature of services pre-approved, the aggregate level of fees approved, or both. Pre-approval of Covered Services by the Chairman pursuant to delegated authority is expected to be the exception rather than the rule and the audit committee may modify or withdraw this delegated authority at any time the audit committee determines that it is appropriate to do so.

     Fee levels for all Covered Services to be provided by the Independent Auditor and pre-approved under this Policy will be established annually by the audit committee and set forth in the Service Pre-Approval Documents. Any increase in pre-approved fee levels will require specific pre-approval by the audit committee (or the Chairman pursuant to delegated authority).

     The terms and fees of the annual Audit services engagement for the Fund are subject to the specific pre-approval of the audit committee. The audit committee (or the Chairman pursuant to delegated authority) will approve, if necessary, any changes in terms, conditions or fees resulting from changes in audit scope, Fund structure or other matters.

     In addition to the annual Audit services engagement specifically approved by the audit committee, any other Audit services for the Fund not listed in the Service Pre-Approval Document for the respective period must be specifically pre-approved by the audit committee (or the Chairman pursuant to delegated authority).

     Audit-Related services are assurance and related services that are not required for the audit, but are reasonably related to the performance of the audit or review of the financial statements of the registrant and, to the extent they are Covered Services, the other Covered Entities (as defined in the Joint Audit Committee Charter) or that are traditionally performed by the Independent Auditor. Audit-Related services that are Covered Services and are not listed in the Service Pre-Approval Document for the respective period must be specifically pre-approved by the audit committee (or the Chairman pursuant to delegated authority).

     The audit committee believes that the Independent Auditor can provide Tax services to the Covered Entities such as tax compliance, tax planning and tax advice without impairing the auditor’s independence. However, the audit committee will not permit the retention of the Independent Auditor in connection with a transaction initially recommended by the Independent Auditor, the sole business purpose of which may be tax avoidance and the tax treatment of which may not be supported in the Internal Revenue Code and related regulations. Tax services that are Covered Services and are not listed in the Service Pre-Approval Document for the respective period must be specifically pre-approved by the audit committee (or the Chairman pursuant to delegated authority).

     All Other services that are covered and are not listed in the Service Pre-Approval Document for the respective period must be specifically pre-approved by the audit committee (or the Chairman pursuant to delegated authority).

     Requests or applications to provide Covered Services that require approval by the audit committee (or the Chairman pursuant to delegated authority) must be submitted to the audit committee or the Chairman, as the case may be, by both the Independent Auditor and the Chief Financial Officer of the respective Covered Entity, and must include a joint statement as to whether, in their view, (a) the request or application is consistent with the rules of the Securities and Exchange Commission ("SEC") on auditor independence and (b) the requested service is or is not a non-audit service prohibited by the SEC. A request or application submitted to the Chairman between scheduled meetings of the audit committee should include a discussion as to why approval is being sought prior to the next regularly scheduled meeting of the audit committee.

(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.

(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 to 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 and employees of any of them has any substantial economic interest or possesses material non-public information. Each portfolio manager also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for the Fund. In this connection, it should be noted that certain portfolio managers, including Mr. Amero, currently manage certain accounts that are subject to performance fees. In addition, certain portfolio managers, including Mr. Amero, 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 December 31, 2007:

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 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 to compare the performance of funds and other accounts managed by each portfolio manager and the period of time over which performance is evaluated. With respect to the Fund’s portfolio managers, such benchmarks include the following:

Portfolio Manager	Benchmarks Applicable to Each Manager
Scott Amero	A combination of market-based indices (e.g., Citigroup 1-
	Year Treasury Index, Merrill Lynch 1-3 Year Treasury Index,
	Lehman Brothers Intermediate Government Index, Lehman
	Brothers Intermediate Gov/Credit Index, Lehman Brothers
	Aggregate Index, Lehman Brothers Intermediate Aggregate
	Index, Lehman Brothers U.S. Corporate High Yield 2% Issuer
	Cap Index and others), certain customized indices and certain
	fund industry peer groups.
John Burger	A combination of certain fund industry peer groups, including
	the Lipper Closed-end Income and Preferred Stock Funds
	classification.
Daniel Chen	A combination of certain fund industry peer groups, including
	the Lipper Closed-end Income and Preferred Stock Funds
	classification.

BlackRock’s Chief Investment Officers make a subjective determination with respect to the portfolio manager’s 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 the Company’s ability to sustain and improve its performance over future periods.

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:

     Long-Term Retention and Incentive Plan (“LTIP”) —The LTIP is a long-term incentive plan that seeks to reward certain key employees. For Messrs. Amero and Chen, 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. Amero, Burger and Chen have each received awards under the LTIP.

     Deferred Compensation Program —A portion of the compensation paid to each portfolio manager may be voluntarily deferred by the portfolio manager into an account that tracks the performance of certain of the firm’s investment products. Each portfolio manager is permitted to allocate his deferred amounts among various options, including to certain of the firm’s hedge funds and other unregistered products. In addition, prior to 2005, a portion of the annual compensation of certain senior managers, including Mr. Amero, was mandatorily deferred in a similar manner for a number of years. Every portfolio manager is eligible to participate in the deferred compensation program.

     Options and Restricted Stock Awards — Prior to mandatorily deferring a portion of a portfolio manager’s annual bonus in BlackRock, Inc. restricted stock units, the Company 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. Amero has been granted stock options and/or restricted stock in prior years.

     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. Company 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.

(a)(4) Beneficial Ownership of Securities. As of December 31, 2007, none of Messrs. Amero, Burger or Chen beneficially owned any stock issued by the Fund.

EX-99.PROXYPOL

Proxy Voting Policies and Procedures

For BlackRock Advisors, LLC
And Its Affiliated SEC Registered Investment Advisers

September 30, 2006

Proxy Voting Policies and Procedures

     These Proxy Voting Policies and Procedures (“Policy”) for BlackRock Advisors, LLC and its affiliated U.S. registered investment advisers¹ (“BlackRock”) reflect our duty as a fiduciary under the Investment Advisers Act of 1940 (the “Advisers Act”) to vote proxies in the best interests of our clients. BlackRock serves as the investment manager for investment companies, other commingled investment vehicles and/or separate accounts of institutional and other clients. The right to vote proxies for securities held in such accounts belongs to BlackRock’s clients. Certain clients of BlackRock have retained the right to vote such proxies in general or in specific circumstances.² Other clients, however, have delegated to BlackRock the right to vote proxies for securities held in their accounts as part of BlackRock’s authority to manage, acquire and dispose of account assets.

     When BlackRock votes proxies for a client that has delegated to BlackRock proxy voting authority, BlackRock acts as the client’s agent. Under the Advisers Act, an investment adviser is a fiduciary that owes each of its clients a duty of care and loyalty with respect to all services the adviser undertakes on the client’s behalf, including proxy voting. BlackRock is therefore subject to a fiduciary duty to vote proxies in a manner BlackRock believes is consistent with the client’s best interests,³ whether or not the client’s proxy voting is subject to the fiduciary standards of the Employee Retirement Income Security Act of 1974 (“ERISA”).⁴ When voting proxies for client accounts (including investment companies), BlackRock’s primary objective is to make voting decisions solely in the best interests of clients and ERISA clients’ plan beneficiaries and participants. In fulfilling its obligations to clients, BlackRock will seek to act in a manner that it believes is most likely to enhance the economic value of the underlying securities held in client accounts.⁵ It is imperative that BlackRock considers the interests of its clients, and not the interests of BlackRock, when voting proxies and that real (or perceived) material conflicts that may arise between BlackRock’s interest and those of BlackRock’s clients are properly addressed and resolved.

____________________

¹ The Policy does not apply to BlackRock Asset Management U.K. Limited and BlackRock Investment Managers International Limited, which are U.S. registered investment advisers based in the United Kingdom.

² In certain situations, a client may direct BlackRock to vote in accordance with the client’s proxy voting policies. In these situations, BlackRock will seek to comply with such policies to the extent it would not be inconsistent with other BlackRock legal responsibilities.

³ Letter from Harvey L. Pitt, Chairman, SEC, to John P.M. Higgins, President, Ram Trust Services (February 12, 2002) (Section 206 of the Investment Advisers Act imposes a fiduciary responsibility to vote proxies fairly and in the best interests of clients); SEC Release No. IA-2106 (February 3, 2003).

⁴ DOL Interpretative Bulletin of Sections 402, 403 and 404 of ERISA at 29 C.F.R. 2509.94 -2

⁵ Other considerations, such as social, labor, environmental or other policies, may be of interest to particular clients. While BlackRock is cognizant of the importance of such considerations, when voting proxies it will generally take such matters into account only to the extent that they have a direct bearing on the economic value of the underlying securities. To the extent that a BlackRock client desires to pursue a particular social, labor, environmental or other agenda through the proxy votes made for its securities held through BlackRock as investment adviser, BlackRock encourages the client to consider retaining direct proxy voting authority or to appoint independently a special proxy voting fiduciary other than BlackRock.

1

     Advisers Act Rule 206(4)-6 was adopted by the SEC in 2003 and requires, among other things, that an investment adviser that exercises voting authority over clients’ proxy voting adopt policies and procedures reasonably designed to ensure that the adviser votes proxies in the best interests of clients, discloses to its clients information about those policies and procedures and also discloses to clients how they may obtain information on how the adviser has voted their proxies.

     In light of such fiduciary duties, the requirements of Rule 206(4)-6, and given the complexity of the issues that may be raised in connection with proxy votes, BlackRock has adopted these policies and procedures. BlackRock’s Equity Investment Policy Oversight Committee, or a sub-committee thereof (the “Committee”), addresses proxy voting issues on behalf of BlackRock and its clients.⁶ The Committee is comprised of senior members of BlackRock’s Portfolio Management Group and advised by BlackRock’s Legal and Compliance Department.

____________________

⁶ Subject to the Proxy Voting Policies of Merrill Lynch Bank & Trust Company FSB, the Committee may also function jointly as the Proxy Voting Committee for Merrill Lynch Bank & Trust Company FSB trust accounts managed by personnel dually-employed by BlackRock.

I.Scope of Committee Responsibilities

     The Committee shall have the responsibility for determining how to address proxy votes made on behalf of all BlackRock clients, except for clients who have retained the right to vote their own proxies, either generally or on any specific matter. In so doing, the Committee shall seek to ensure that proxy votes are made in the best interests of clients, and that proxy votes are determined in a manner free from unwarranted or inappropriate influences. The Committee shall also oversee the overall administration of proxy voting for BlackRock accounts.⁷

     The Committee shall establish BlackRock’s proxy voting guidelines, with such advice, participation and research as the Committee deems appropriate from portfolio managers, proxy voting services or other knowledgeable interested parties. As it is anticipated that there will not necessarily be a “right” way to vote proxies on any given issue applicable to all facts and circumstances, the Committee shall also be responsible for determining how the proxy voting guidelines will be applied to specific proxy votes, in light of each issuer’s unique structure, management, strategic options and, in certain circumstances, probable economic and other anticipated consequences of alternative actions. In so doing, the Committee may determine to vote a particular proxy in a manner contrary to its generally stated guidelines.

     The Committee may determine that the subject matter of certain proxy issues are not suitable for general voting guidelines and requires a case-by-case determination, in which case the Committee may elect not to adopt a specific voting guideline applicable to such issues. BlackRock believes that certain proxy voting issues – such as approval of mergers and other significant corporate transactions – require investment analysis akin to investment decisions, and are therefore not suitable for general guidelines. The Committee may elect to adopt a common BlackRock position on certain proxy votes that are akin to investment decisions, or determine to permit portfolio managers to make individual decisions on how best to maximize economic value for the accounts for which they are responsible (similar to normal buy/sell investment decisions made by such portfolio managers).⁸

     While it is expected that BlackRock, as a fiduciary, will generally seek to vote proxies over which BlackRock exercises voting authority in a uniform manner for all BlackRock clients, the Committee, in conjunction with the portfolio manager of an account, may determine that the specific circumstances of such account require that such account’s proxies be voted differently due to such account’s investment objective or other factors that differentiate it from other accounts. In addition, on proxy votes that are akin to investment decisions, BlackRock believes portfolio managers may from time to time

____________________

⁷ The Committee may delegate day-to-day administrative responsibilities to other BlackRock personnel and/or outside service providers, as appropriate.

⁸ The Committee will normally defer to portfolio managers on proxy votes that are akin to investment decisions except for proxy votes that involve a material conflict of interest, in which case it will determine, in its discretion, the appropriate voting process so as to address such conflict.

legitimately reach differing but equally valid views, as fiduciaries for BlackRock’s clients, on how best to maximize economic value in respect of a particular investment.

     The Committee will also be responsible for ensuring the maintenance of records of each proxy vote, as required by Advisers Act Rule 204-2.⁹ All records will be maintained in accordance with applicable law. Except as may be required by applicable legal requirements, or as otherwise set forth herein, the Committee’s determinations and records shall be treated as proprietary, nonpublic and confidential.

     The Committee shall be assisted by other BlackRock personnel, as may be appropriate. In particular, the Committee has delegated to the BlackRock Operations Department responsibility for monitoring corporate actions and ensuring that proxy votes are submitted in a timely fashion. The Operations Department shall ensure that proxy voting issues are promptly brought to the Committee’s attention and that the Committee’s proxy voting decisions are appropriately disseminated and implemented.

     To assist BlackRock in voting proxies, the Committee may retain the services of a firm providing such services. BlackRock has currently retained Institutional Shareholder Services (“ISS”) in that role. ISS is an independent adviser that specializes in providing a variety of fiduciary-level proxy-related services to institutional investment managers, plan sponsors, custodians, consultants, and other institutional investors. The services provided to BlackRock may include, but are not limited to, in-depth research, voting recommendations (which the Committee is not obligated to follow), vote execution, and recordkeeping.

____________________

⁹ The Committee may delegate the actual maintenance of such records to an outside service provider. Currently, the Committee has delegated the maintenance of such records to Institutional Shareholder Services.

II.Special Circumstances

     Routine Consents. BlackRock may be asked from time to time to consent to an amendment to, or grant a waiver under, a loan agreement, partnership agreement, indenture or other governing document of a specific financial instrument held by BlackRock clients. BlackRock will generally treat such requests for consents not as “proxies” subject to these Proxy Voting Policies and Procedures but as investment matters to be dealt with by the responsible BlackRock investment professionals would, provided that such consents (i) do not relate to the election of a board of directors or appointment of auditors of a public company, and (ii) either (A) would not otherwise materially affect the structure, management or control of a public company, or (B) relate to a company in which BlackRock clients hold only interests in bank loans or debt securities and are consistent with customary standards and practices for such instruments.

     Securities on Loan. Registered investment companies that are advised by BlackRock as well as certain of our advisory clients may participate in securities lending programs. Under most securities lending arrangements, securities on loan may not be voted by the lender (unless the loan is recalled). BlackRock believes that each client has the right to determine whether participating in a securities lending program enhances returns, to contract with the securities lending agent of its choice and to structure a securities lending program, through its lending agent, that balances any tension between loaning and voting securities in a matter that satisfies such client. If client has decided to participate in a securities lending program, BlackRock will therefore defer to the client’s determination and not attempt to seek recalls solely for the purpose of voting routine proxies as this could impact the returns received from securities lending and make the client a less desirable lender in a marketplace. Where a client retains a lending agent that is unaffiliated with BlackRock, BlackRock will generally not seek to vote proxies relating to securities on loan because BlackRock does not have a contractual right to recall such loaned securities for the purpose of voting proxies. Where BlackRock or an affiliate acts as the lending agent, BlackRock will also generally not seek to recall loaned securities for proxy voting purposes, unless the portfolio manager responsible for the account or the Committee determines that voting the proxy is in the client’s best interest and requests that the security be recalled.

     Voting Proxies for Non-US Companies. While the proxy voting process is well established in the United States, voting proxies of non-US companies frequently involves logistical issues which can affect BlackRock’s ability to vote such proxies, as well as the desirability of voting such proxies. These issues include (but are not limited to): (i) untimely notice of shareholder meetings, (ii) restrictions on a foreigner’s ability to exercise votes, (iii) requirements to vote proxies in person, (iv) “shareblocking” (requirements that investors who exercise their voting rights surrender the right to dispose of their holdings for some specified period in proximity to the shareholder meeting), (v) potential difficulties in translating the proxy, and (vi) requirements to provide local agents with unrestricted powers of attorney to facilitate voting instructions.

5

     As a consequence, BlackRock votes proxies of non-US companies only on a “best-efforts” basis. In addition, the Committee may determine that it is generally in the best interests of BlackRock clients not to vote proxies of companies in certain countries if the Committee determines that the costs (including but not limited to opportunity costs associated with shareblocking constraints) associated with exercising a vote generally are expected to outweigh the benefit the client will derive by voting on the issuer’s proposal. If the Committee so determines in the case of a particular country, the Committee (upon advice from BlackRock portfolio managers) may override such determination with respect to a particular issuer’s shareholder meeting if the Committee believes the benefits of seeking to exercise a vote at such meeting outweighs the costs, in which case BlackRock will seek to vote on a best-efforts basis.

     Securities Sold After Record Date. With respect to votes in connection with securities held on a particular record date but sold from a client account prior to the holding of the related meeting, BlackRock may take no action on proposals to be voted on in such meeting.

     Conflicts of Interest. From time to time, BlackRock may be required to vote proxies in respect of an issuer that is an affiliate of BlackRock (a “BlackRock Affiliate”), or a money management or other client of BlackRock (a “BlackRock Client”).¹⁰ In such event, provided that the Committee is aware of the real or potential conflict, the following procedures apply:

• The Committee intends to adhere to the voting guidelines set forth herein for all proxy issues including matters involving BlackRock Affiliates and BlackRock Clients. The Committee may, in its discretion for the purposes of ensuring that an independent determination is reached, retain an independent fiduciary to advise the Committee on how to vote or to cast votes on behalf of BlackRock’s clients; and

• if the Committee determines not to retain an independent fiduciary, or does not desire to follow the advice of such independent fiduciary, the Committee shall determine how to vote the proxy after consulting with the BlackRock Legal and Compliance Department and concluding that the vote cast is in the client’s best interest notwithstanding the conflict.

____________________

¹⁰ Such issuers may include investment companies for which BlackRock provides investment advisory, administrative and/or other services.

III. Voting Guidelines

     The Committee has determined that it is appropriate and in the best interests of BlackRock’s clients to adopt the following voting guidelines, which represent the Committee’s usual voting position on certain recurring proxy issues that are not expected to involve unusual circumstances. With respect to any particular proxy issue, however, the Committee may elect to vote differently than a voting guideline if the Committee determines that doing so is, in the Committee’s judgment, in the best interest of its clients. The guidelines may be reviewed at any time upon the request of any Committee member and may be amended or deleted upon the vote of a majority of voting Committee members present at a Committee meeting for which there is a quorum.

     A. Boards of Directors

     These proposals concern those issues submitted to shareholders relating to the composition of the Board of Directors of companies other than investment companies. As a general matter, the Committee believes that a company’s Board of Directors (rather than shareholders) is most likely to have access to important, nonpublic information regarding a company’s business and prospects, and is therefore best-positioned to set corporate policy and oversee management. The Committee therefore believes that the foundation of good corporate governance is the election of qualified, independent corporate directors who are likely to diligently represent the interests of shareholders and oversee management of the corporation in a manner that will seek to maximize shareholder value over time. In individual cases, the Committee may look at a Director nominee’s history of representing shareholder interests as a director of other companies, or other factors to the extent the Committee deems relevant.

     The Committee’s general policy is to vote:

#
	VOTE and DESCRIPTION
A.1	FOR nominees for director of United States companies in
	uncontested elections, except for nominees who
	•	have missed at least two meetings and, as a result,
		attended less than 75% of meetings of the Board of
		Directors and its committees the previous year, unless the
		nominee missed the meeting(s) due to illness or company
		business
	•	voted to implement or renew a “dead-hand” poison pill
	•	ignored a shareholder proposal that was approved by
		either a majority of the shares outstanding in any year or
		by the majority of votes cast for two consecutive years
	•	failed to act on takeover offers where the majority of the
		shareholders have tendered their shares
	•	are corporate insiders who serve on the audit,
		compensation or nominating committees or on a full
		Board that does not have such committees composed
		exclusively of independent directors
	•	on a case-by-case basis, have served as directors of other
		companies with allegedly poor corporate governance
	•	sit on more than six boards of public companies
A.2	FOR nominees for directors of non-U.S. companies in uncontested
	elections, except for nominees from whom the Committee
	determines to withhold votes due to the nominees’ poor records of
	representing shareholder interests, on a case-by-case basis
A.3	FOR proposals to declassify Boards of Directors, except where
	there exists a legitimate purpose for classifying boards
A.4	AGAINST proposals to classify Boards of Directors, except where
	there exists a legitimate purpose for classifying boards

8

A.5	AGAINST proposals supporting cumulative voting
A.6	FOR proposals eliminating cumulative voting
A.7	FOR proposals supporting confidential voting

	representation of women and/or minorities generally (i.e., not
	specific individuals) to a Board of Directors
A.10	AGAINST shareholder proposals for term limits for directors
A.11	FOR shareholder proposals to establish a mandatory retirement
	age for directors who attain the age of 72 or older
A.12	AGAINST shareholder proposals requiring directors to own a
	minimum amount of company stock
A.13	FOR proposals requiring a majority of independent directors on a
	Board of Directors

A.20	AGAINST proposals to eliminate shareholder ability to nominate
	directors directly
A.21	FOR proposals permitting shareholder ability to remove directors
	directly
A.22	AGAINST proposals to eliminate shareholder ability to remove
	directors directly

9

     B. Auditors

     These proposals concern those issues submitted to shareholders related to the selection of auditors. As a general matter, the Committee believes that corporate auditors have a responsibility to represent the interests of shareholders and provide an independent view on the propriety of financial reporting decisions of corporate management. While the Committee will generally defer to a corporation’s choice of auditor, in individual cases, the Committee may look at an auditors’ history of representing shareholder interests as auditor of other companies, to the extent the Committee deems relevant.

     The Committee’s general policy is to vote:

B.1	FOR approval of independent auditors, except for
	•	auditors that have a financial interest in, or material
		association with, the company they are auditing, and are
		therefore believed by the Committee not to be independent
	•	auditors who have rendered an opinion to any company which
		in the Committee’s opinion is either not consistent with best
		accounting practices or not indicative of the company’s
		financial situation
	•	on a case-by-case basis, auditors who in the Committee’s
		opinion provide a significant amount of non-audit services to
		the company
B.2	FOR proposals seeking authorization to fix the remuneration of
	auditors
B.3	FOR approving internal statutory auditors
B.4	FOR proposals for audit firm rotation, except for proposals that
	would require rotation after a period of less than 5 years

10

     C. Compensation and Benefits

     These proposals concern those issues submitted to shareholders related to management compensation and employee benefits. As a general matter, the Committee favors disclosure of a company’s compensation and benefit policies and opposes excessive compensation, but believes that compensation matters are normally best determined by a corporation’s board of directors, rather than shareholders. Proposals to “micro-manage” a company’s compensation practices or to set arbitrary restrictions on compensation or benefits will therefore generally not be supported.

     The Committee’s general policy is to vote:

C.1	IN ACCORDANCE WITH THE RECOMMENDATION OF ISS
	on compensation plans if the ISS recommendation is based solely
	on whether or not the company’s plan satisfies the allowable cap
	as calculated by ISS. If the recommendation of ISS is based on
	factors other than whether the plan satisfies the allowable cap the
	Committee will analyze the particular proposed plan. This policy
	applies to amendments of plans as well as to initial approvals.
C.2	FOR proposals to eliminate retirement benefits for outside
	directors
C.3	AGAINST proposals to establish retirement benefits for outside
	directors
C.4	FOR proposals approving the remuneration of directors or of
	supervisory board members
C.5	AGAINST proposals to reprice stock options
C.6	FOR proposals to approve employee stock purchase plans that
	apply to all employees. This policy applies to proposals to amend
	ESPPs if the plan as amended applies to all employees.
C.7	FOR proposals to pay retirement bonuses to directors of Japanese
	companies unless the directors have served less than three years
C.8	AGAINST proposals seeking to pay outside directors only in stock
C.9	FOR proposals seeking further disclosure of executive pay or
	requiring companies to report on their supplemental executive
	retirement benefits
C.10	AGAINST proposals to ban all future stock or stock option grants
	to executives
C.11	AGAINST option plans or grants that apply to directors or
	employees of “related companies” without adequate disclosure of
	the corporate relationship and justification of the option policy
C.12	FOR proposals to exclude pension plan income in the calculation
	of earnings used in determining executive bonuses/compensation

11

     D. Capital Structure

     These proposals relate to various requests, principally from management, for approval of amendments that would alter the capital structure of a company, such as an increase in authorized shares. As a general matter, the Committee will support requests that it believes enhance the rights of common shareholders and oppose requests that appear to be unreasonably dilutive.

     The Committee’s general policy is to vote:

D.1	AGAINST proposals seeking authorization to issue shares without
	preemptive rights except for issuances up to 10% of a non-US
	company’s total outstanding capital
D.2	FOR management proposals seeking preemptive rights or seeking
	authorization to issue shares with preemptive rights
D.3	FOR management proposals approving share repurchase programs
D.4	FOR management proposals to split a company’s stock
D.5	FOR management proposals to denominate or authorize
	denomination of securities or other obligations or assets in Euros
D.6	FOR proposals requiring a company to expense stock options
	(unless the company has already publicly committed to do so by a
	certain date).

12

     E. Corporate Charter and By-Laws

     These proposals relate to various requests for approval of amendments to a corporation’s charter or by-laws, principally for the purpose of adopting or redeeming “poison pills”. As a general matter, the Committee opposes poison pill provisions.

     The Committee’s general policy is to vote:

E.1	AGAINST proposals seeking to adopt a poison pill
E.2	FOR proposals seeking to redeem a poison pill
E.3	FOR proposals seeking to have poison pills submitted to
	shareholders for ratification
E.4	FOR management proposals to change the company’s name

13

     F. Corporate Meetings

     These are routine proposals relating to various requests regarding the formalities of corporate meetings.

     The Committee’s general policy is to vote:

F.1	AGAINST proposals that seek authority to act on “any other
	business that may arise”
F.2	FOR proposals designating two shareholders to keep minutes of
	the meeting
F.3	FOR proposals concerning accepting or approving financial
	statements and statutory reports
F.4	FOR proposals approving the discharge of management and the
	supervisory board
F.5	FOR proposals approving the allocation of income and the
	dividend
F.6	FOR proposals seeking authorization to file required
	documents/other formalities
F.7	FOR proposals to authorize the corporate board to ratify and
	execute approved resolutions
F.8	FOR proposals appointing inspectors of elections
F.9	FOR proposals electing a chair of the meeting
F.10	FOR proposals to permit “virtual” shareholder meetings over the
	Internet
F.11	AGAINST proposals to require rotating sites for shareholder
	meetings

14

     G. Investment Companies

     These proposals relate to proxy issues that are associated solely with holdings of shares of investment companies, including, but not limited to, investment companies for which BlackRock provides investment advisory, administrative and/or other services. As with other types of companies, the Committee believes that a fund’s Board of Directors (rather than its shareholders) is best-positioned to set fund policy and oversee management. However, the Committee opposes granting Boards of Directors authority over certain matters, such as changes to a fund’s investment objective, that the Investment Company Act of 1940 envisions will be approved directly by shareholders.

     The Committee’s general policy is to vote:

G.1		FOR nominees for director of mutual funds in uncontested
		elections, except for nominees who
	•	have missed at least two meetings and, as a result, attended
		less than 75% of meetings of the Board of Directors and its
		committees the previous year, unless the nominee missed the
		meeting due to illness or fund business
	•	ignore a shareholder proposal that was approved by either a
		majority of the shares outstanding in any year or by the
		majority of votes cast for two consecutive years
	•	are interested directors who serve on the audit or nominating
		committees or on a full Board that does not have such
		committees composed exclusively of independent directors
	•	on a case-by-case basis, have served as directors of companies
		with allegedly poor corporate governance
G.2		FOR the establishment of new series or classes of shares
G.3		AGAINST proposals to change a fund’s investment objective to
		nonfundamental
G.4		FOR proposals to establish a master-feeder structure or
		authorizing the Board to approve a master-feeder structure without
		a further shareholder vote
G.5		AGAINST a shareholder proposal for the establishment of a
		director ownership requirement
G.6		FOR classified boards of closed-end investment companies

15

     H. Environmental and Social Issues

     These are shareholder proposals to limit corporate conduct in some manner that relates to the shareholder’s environmental or social concerns. The Committee generally believes that annual shareholder meetings are inappropriate forums for the discussion of larger social issues, and opposes shareholder resolutions “micromanaging” corporate conduct or requesting release of information that would not help a shareholder evaluate an investment in the corporation as an economic matter. While the Committee is generally supportive of proposals to require corporate disclosure of matters that seem relevant and material to the economic interests of shareholders, the Committee is generally not supportive of proposals to require disclosure of corporate matters for other purposes.

     The Committee’s general policy is to vote:

H.1	AGAINST proposals seeking to have companies adopt
	international codes of conduct
H.2	AGAINST proposals seeking to have companies provide non-
	required reports on:
	•	environmental liabilities;
	•	bank lending policies;
	•	corporate political contributions or activities;
	•	alcohol advertising and efforts to discourage drinking by
		minors;
	•	costs and risk of doing business in any individual country;
	•	involvement in nuclear defense systems
H.3	AGAINST proposals requesting reports on Maquiladora
	operations or on CERES principles
H.4	AGAINST proposals seeking implementation of the CERES
	principles

16

Notice to Clients

     BlackRock will make records of any proxy vote it has made on behalf of a client available to such client upon request.¹¹ BlackRock will use its best efforts to treat proxy votes of clients as confidential, except as it may decide to best serve its clients’ interests or as may be necessary to effect such votes or as may be required by law.

     BlackRock encourage clients with an interest in particular proxy voting issues to make their views known to BlackRock, provided that, in the absence of specific written direction from a client on how to vote that client’s proxies, BlackRock reserves the right to vote any proxy in a manner it deems in the best interests of its clients, as it determines in its sole discretion.

     These policies are as of the date indicated on the cover hereof. The Committee may subsequently amend these policies at any time, without notice.
