A Letter to Shareholders

THIS PAGE NOT PART OF YOUR FUND REPORT

Dear Shareholder Throughout the past year, investors were overwhelmed by lingering credit and financial market troubles, surging oil prices and more recently, renewed inflation concerns. Healthy nonfinancial corporate profits and robust exporting activity remained among the few bright spots, helping the economy to grow at a modest, but still positive, pace. The Federal Reserve Board (the “Fed”) has been aggressive in its attempts to stoke economic growth and ease financial market instability. In addition to slashing the target federal funds rate 325 basis points (3.25%) between September 2007 and April 2008, the central bank introduced the new Term Securities Lending Facility, granted broker-dealers access to the discount window and used its own balance sheet to help negotiate the sale of Bear Stearns. As widely anticipated, the end of the period saw a pause in Fed action, as the central bank held the target rate steady at 2.0% amid rising inflationary pressures. As the Fed’s bold response to the financial crisis helped ease credit turmoil and investor anxiety, U.S. equity markets sank sharply over the last six months, notwithstanding a brief rally in the spring. International markets were not immune to the tumult, with most regions also registering declines. Treasury securities also traded in a volatile fashion, but generally rallied (yields fell as prices correspondingly rose), with investors continuing to seek safety as part of a broader flight to quality. The yield on 10-year Treasury issues, which fell to 3.34% in March 2008, climbed up to the 4.20% range in mid-June as investors temporarily shifted out of Treasury issues in favor of riskier assets (such as stocks and other high-quality fixed income sectors), then reversed course and declined to 3.99% by period-end when credit fears re-emerged. Tax-exempt issues eked out gains for the reporting period, but underperformed their taxable counterparts, as the group continued to be pressured by problems among municipal bond insurers and the breakdown in the market for auction rate securities. The major benchmark indexes generated results that largely reflected heightened investor risk aversion:

Trust Summary as of June 30, 2008

BlackRock Global Floating Rate Income Trust

Investment Objective

BlackRock Global Floating Rate Income Trust (BGT) (the “Trust”) seeks to provide a high level of current income and to seek the preservation of capital.

Performance

For the six months ended June 30, 2008, the Trust returned (2.21)% based on market price and (2.82)% based on net asset value (“NAV”). For the same period, the closed-end Lipper Loan Participation Funds category posted an average return of (4.17)% on a NAV basis. All returns reflect reinvestment of dividends. The Trust was conservatively positioned in an adverse market for floating-rate loans, which aided relative performance. The Trust’s allocations to high yield (15% at 3/31/08) and investment-grade corporates (7.5% at 3/31/08) also aided relative performance as those sectors outperformed loans. During the period, the Trust’s discount to NAV narrowed modestly, which accounts for the difference between performance based on price and performance based on NAV.

The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

BlackRock High Income Shares

Investment Objective

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

Performance

For the six months ended June 30, 2008, the Trust returned (0.05)% based on market price and (2.00)% based on NAV. For the same period, the closed-end Lipper High Current Yield Funds (Leveraged) category posted an average return of (8.34)% on a NAV basis. All returns reflect reinvestment of dividends. The Trust was conservatively positioned in an adverse market, which aided relative performance. The Trust also was moderately leveraged relative to its peers (17% at 3/31/08), which also aided relative results. During the period, the Trust’s discount to NAV narrowed modestly, which accounts for the difference between performance based on price and performance based on NAV.

Trust Summary as of June 30, 2008

BlackRock Preferred Opportunity Trust

Investment Objective

BlackRock Preferred Opportunity Trust (BPP) (the “Trust”) seeks to provide a high level of current income consistent with capital preservation.

Performance

For the six months ended June 30, 2008, the Trust returned 5.09% based on market price and (6.62)% based on NAV. For the same period, the closed-end Lipper Income & Preferred Stock Funds category posted an average return of (9.44)% on a NAV basis. All returns reflect reinvestment of dividends. The Trust was 65% invested in the banking and insurance sector, which makes up most of the market. This detracted from performance as the financial sector came under pressure during the period. The Trust maintained an underweight to $25 par preferreds, which we believed would underperform. This generally hurt relative performance, but began to aid results later in the period as these securities’ prices began to drop. Additionally, many of the funds in the Lipper category also are equity funds, and equities underperformed preferreds during the period.

The Benefits and Risks of Leveraging

The Trusts utilize leveraging through borrowings or issuance of short-term debt securities. The concept of leveraging is based on the premise that the cost of assets to be obtained from leverage will be based on short-term interest rates, or dividends on Preferred Shares, 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 Shareholders will be the beneficiaries of the incremental yield.

Leverage creates risks for holders of Common Shares including the likelihood of greater NAV and market price volatility. In addition, there is the risk that fluctuations in interest rates on borrowings (or in the dividend rates on any Preferred Shares) may reduce the Common Shares’ yield and negatively impact its NAV and market price. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, 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 Shareholders will be reduced.

As of June 30, 2008, the Trusts incurred leverage as a percentage of managed assets, as set forth in the table below. BGT’s leverage is from borrowings through a credit facility and its issuance of Preferred Shares. HIS’s leverage is from borrowings through a credit facility. BPP’s leverage is from reverse repurchase agreements and its issuance of Preferred Shares. The Trusts are subject to certain leverage limitations, including limitations under the Investment Company Act of 1940. As of June 30, 2008, the Trusts were in compliance with those leverage limitations.

		Leverage as of June 30, 2008
BlackRock Global Floating Rate Income Trust (BGT)		38%
BlackRock High Income Shares (HIS)		15%
BlackRock Preferred Opportunity Trust (BPP)		39%

Swap Agreements

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

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

•

Level 1 - price quotations in active markets/exchanges for identical securities

•

Level 2 - other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs)

•

Level 3 - unobservable inputs based on the best information available in the circumstance, to the extent observable inputs are not available (including the Trust’s own assumption used in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Trust's policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

The following table summarizes the inputs used as of June 30, 2008 in determining the fair valuation of the Trust's investments:

Valuation Inputs	Investments in Securities		Other Financial Instruments*
Level 1	$	379,975	$	321,299
Level 2		622,458,752		(419,722	)
Level 3		1,976,711		—
Total	$	624,815,438	$	(98,423	)

*	Other financial instruments are swaps, forward foreign currency contracts and options.

The following is a reconciliation of investments for unobservable inputs (Level 3) were used in determining fair value:

Notes to Financial Statements (Unaudited)

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 principles 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 their bond investments on the basis of last available bid price or current market quotations provided by dealers or pricing services selected under the supervision each Trust’s respective Board of Directors or Trustees (the “Board”). Financial futures contracts traded on exchanges are valued at their last sale price. Swap agreements are valued by quoted fair values received daily by the Trusts’ pricing service or through brokers. Short-term securities are valued at amortized cost. Floating rate loan interests are valued at the mean between the last available bid prices from one or more brokers or dealers as obtained from a pricing service. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments, various relationships observed in the market between investments and calculated yield measures based on valuation technology commonly employed in the market for such investments.

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

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

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

Generally, trading in foreign securities is substantially completed each day at various times prior to the close of business on the New York Stock Exchange (“NYSE”). The values of such securities used in computing the net assets of each Trust are determined as of such times. Foreign currency exchange rates will be determined as of the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Trust’s net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities may be valued at their fair value as determined in good faith by the Board or by the investment advisor using a pricing service and/or procedures approved by the Board.

Derivative Financial Instruments: The Trusts may engage in various Trust 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 if the value of the contract decreases due to an unfavorable change in the price of the underlying security, or if the counterparty does not perform under the contract.

•

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

•

Forward foreign currency contracts — Each Trust may enter into forward foreign currency contracts as a hedge against either specific transactions or Trust positions. Forward currency contracts, when used by the Trust, help to manage the overall exposure to the foreign currency backing some of the investments held by the Trust. The contract is marked-to-market daily and the change in market value is recorded by the Trust as an unrealized gain or loss. When the contract is closed, the Trust records




32	SEMI-ANNUAL REPORT	JUNE 30, 2008

Notes to Financial Statements (continued)

a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed.

•

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

A call option gives the purchaser of the option the right (but not the obligation) to buy, and obligates the seller to sell (when the option is exercised), the underlying position at the exercise price at any time or at a specified time during the option period. A put option gives the holder the right to sell and obligates the writer to buy the underlying position at the exercise price at any time or at a specified time during the option period.

•

Swaps — Each Trust may enter into swap agreements, in which the Trust and a counterparty agree to make periodic net payments on a specified notional amount. These periodic payments received or made by the Trust are recorded in the accompanying Statement of Operations as realized gains or losses, respectively. Gains or losses are realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). When the swap is terminated, the Trust will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Trust’s basis in the contract, if any.

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

Interest rate swaps — Interest rate swaps are agreements in which one party pays a floating rate of interest on a notional principal amount and receives a fixed rate of interest on the same notional principal amount for a specified period of time. Alternatively, a party may pay a fixed rate and receive a floating rate. In more complex swaps, the notional principal amount may decline (or amortize) over time.

Total return swaps — Total return swaps are agreements in which one party commits to pay interest in exchange for a market-linked return. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the Trust will receive a payment from or make a payment to the counterparty.

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

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

Capital Trusts/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.

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

The Trust earns and/or pays facility and other fees on floating rate loans. Other fees earned/paid include commitment, amendment, consent, commissions and prepayment penalty fees. Facility, amendment and consent fees are typically amortized as premium and/or accreted as discount over the term of the loan. Commitment, commission and various other fees are recorded as income or expense. Prepayment penalty fees are recorded as gains or losses. When the Trust buys a floating rate loan it may receive a facility fee and when it sells a floating rate loan it may pay a facility fee. On an ongoing basis, the Trust may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a floating rate loan. In certain circumstances, the Trust may receive a prepayment penalty fee upon the prepayment of a floating rate loan by a borrower. Other fees received by the Trust may include covenant waiver fees and covenant modification fees.

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

Floating rate loans are usually freely callable at the issuer’s option. The Trust may invest in such loans in the form of participations in loans (“Participations”) and assignments of all or a portion of loans from third




SEMI-ANNUAL REPORT	JUNE 30, 2008	33

Notes to Financial Statements (continued)

parties. Participations typically will result in the Trust having a contractual relationship only with the lender, not with the borrower.

The Trust will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the Participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing Participations, the Trust generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loans, nor any rights of offset against the borrower, and the Trust may not benefit directly from any collateral supporting the loan in which it has purchased the Participation. As a result, the Trust will assume the credit risk of both the borrower and the lender that is selling the Participation. The Trust’s investments in loan participation interests involve the risk of insolvency of the financial intermediaries who are parties to the transactions. In the event of the insolvency of the lender selling the Participation, the Trust may be treated as a general creditor of the lender and may not benefit from any offset between the lender and the borrower.

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

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 Trust enters into a reverse repurchase agreement, it identifies for segregation certain liquid securities having a value not less than the repurchase price, including accrued interest, of the reverse repurchase agreement. The Trust may utilize reverse repurchase agreements when it is anticipated that the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction.

Reverse repurchase agreements involve the risk that the market value of the securities retained in lieu of sale by a Trust may decline below the price of the securities the Trust has sold but is obligated to repurchase. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, such buyer or its trustee or receiver may receive an extension of time to determine whether to enforce a Trust’s obligations to repurchase the securities and the Trust’s use of the proceeds of the reverse repurchase agreement may effectively be restricted pending such decision.

Segregation: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission (“SEC”) require that the Trusts segregate assets in connection with certain investments (e.g., futures) or certain borrowings, 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.

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 dates. Interest income is recognized on the accrual basis. The Trusts amortize all premiums and discounts on debt securities.

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.

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

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 Trusts’ state and local tax returns may remain open for an additional year depending upon the jurisdiction.

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

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

to match its deferred compensation obligations. Investments to cover the Trusts’ deferred compensation liability, if any, are included in other assets on the Statement of Assets and Liabilities.

Recent Accounting Pronouncement: In March 2008, Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities – an amendment of FASB Statement No. 133” (“FAS 161”) was issued and is effective for fiscal years beginning after November 15, 2008. FAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity’s results of operations and financial position. The impact on the Trusts’ financial statement disclosures, if any, is currently being assessed.

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

2. Investment Advisory Agreement and Other Transactions with Affiliates:

Each Trust has an Investment Advisory Agreement (“the Agreements”) with BlackRock Advisors, LLC (the “Advisor”), an indirect, wholly owned subsidiary of BlackRock, Inc. 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 Advisor is responsible for the management of the Trust’s portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Trust. 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 has entered into a separate sub-advisory agreement with BlackRock Financial Management, Inc. (“BFM”), an affiliate of the Advisor, under which the Advisor pays BFM for services it provides, a monthly fee that is a percentage of the investment advisory fee paid by each Trust to the Advisor.

For the six months ended June 30, 2008 the Trusts reimbursed the Advisor for certain accounting services, which is included in accounting services in the Statement of Operations as follows:

		Reimbursement From Advisor
Global		$ 5,231
High Income		$ 1,059
Preferred		$ 4,764

3. Investments:

Purchases and sales of investments (including paydowns and payups), excluding short-term securities, for the six months ended June 30, 2008, were as follows:

	BlackRock Global Floating Rate Income Trust		BlackRock High Income Shares		BlackRock Preferred Opportunity Trust
Total Purchases	$	103,776,955	$	29,838,861	$	266,878,948
Total Sales	$	120,565,334	$	49,769,974	$	292,157,837

4. Capital Share Transactions:

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 June 30, 2008, the shares owned by affiliates of the Advisor of Global were 7,551.

During the six months ended June 30, 2008 and the year ended December 31, 2007, the Trusts issued the following additional shares under their respective dividend reinvestment plans:

	June 30, 2008	December 31, 2007
Global	—	42,574
High Income	—	—
Preferred Opportunity	—	30,981

As of June 30, 2008, Global and Preferred Opportunity have the following series of Preferred Shares outstanding as listed in the table below. The Preferred Shares have a liquidation value of $25,000 per share plus any accumulated unpaid dividends.

	Series	Shares
Global	T7	784
	W7	784
	R7	784
Preferred Opportunity	T7	1,472
	W7	1,472
	R7	1,472

On May 19, 2008, the Trust announced the following redemptions of Preferred Shares at a price of $25,000 per share plus any accrued and unpaid dividends through the redemption date:

W7	6/12/2008	1,472	$36,800,000
R7	6/13/2008	1,472	$36,800,000

The Trust financed the Preferred Shares redemptions with cash received from reverse repurchase agreements.

Dividends on seven-day Preferred Shares are cumulative at a rate that is reset every seven days based on the results of an auction. If the Preferred Shares fail to clear the auction on an auction date, the Trusts are required to pay the maximum applicable rate on the Preferred Shares to holders of such shares for successive dividend periods until such time as the shares are successfully auctioned. The maximum applicable rate on 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 six months ended June 30, 2008, Preferred Shares of the Trusts were successfully auctioned at each auction date until February 13, 2008. The dividend ranges on the Preferred Shares for Global and Preferred Opportunity for the six months ended June 30, 2008 were as follows:

	Series	Low		High		Average
Global	T7	3.55	%	5.60	%	4.111	%
	W7	3.55		5.00		4.093
	R7	3.549		5.00		4.083

Preferred Opportunity	T7	3.32		5.50		4.022
	W7	3.22		5.25		3.966
	R7	3.231		5.00		3.987

Since February 13, 2008, the Preferred Shares of the Trusts failed to clear any of their auctions. As a result, the Preferred Shares dividend rates were reset to the maximum applicable rate, which ranged from 3.22% to 4.65%. A failed auction is not an event of default for the Trust but it is a liquidity event for the holders of the Preferred Shares. A failed auction occurs when there are more sellers of a Trust’s Preferred Shares than buyers. It is impossible to predict how long this imbalance will last. A successful auction for the Trust’s Preferred Shares may not occur for some time, if ever, and even if liquidity does resume, holders of Preferred Shares may not have the ability to sell the Preferred Shares at its liquidation preference.

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 Preferred Shares is less than 200%.

The 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 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 the Trust, as set forth in the Trust’s Statement of Preferences, are not satisfied.

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

5. Short-Term Borrowings:

Global and High Income are a party to a revolving credit and security agreement funded by a commercial paper asset securitization program with Citicorp North America, Inc. (“Citicorp”), as Agent, certain secondary backstop lenders and certain asset securitization conduits, as lenders (the “Lenders”). The agreement was renewed for one year and has a maximum limit of $190,000,000 for Global and $80,000,000 for High Income. Under the Citicorp administered program, the conduits will fund advances to the Trusts through highly rated commercial paper. The Trusts have granted a security interest in substantially all of its assets to, and in favor of, the Lenders as security for its obligations to the Lenders. The interest rate on the Trusts borrowings is based on the interest rate carried by the commercial paper plus a program fee. In addition, the Trusts pay a liquidity fee to the secondary backstop lenders and the agent. These amounts are shown on the Statement of Operations as borrowing costs.

For the six months ended June 30, 2008, the Global Floating Rate Income Trust’s daily weighted average interest rate was 3.31%.

6. Reverse Repurchase Agreements:

For the six months ended June 30, 2008, Global Floating Rate Income Trust’s average amount outstanding was approximately $453,000 and the daily weighted average interest rate was 2.25%.

For the six months ended June 30, 2008, Preferred Opportunity Trust’s average amount outstanding was approximately $12,773,000 and the daily weighted average interest rate was 3.44%.

SEMI-ANNUAL REPORT	JUNE 30, 2008	37

Disclosure of Investment Advisory Agreement and Subadvisory Agreement

The Board of Trustees (collectively, the “Board,” the members of which are referred to as “Trustees”) of the BlackRock Global Floating Rate Income Trust (“BGT”), BlackRock High Income Shares (“HIS”) and BlackRock Preferred Opportunity Trust (“BPP”), and together with HIS and BGT, the “Funds”) met in April and May 2008 to consider approving the continuation of each Fund’s investment advisory agreement (each, an “Advisory Agreement”) with BlackRock Advisors, LLC (the “Advisor”), each Fund’s investment adviser. The Board also considered the approval of each Fund’s subadvisory agreement (each, a “Subadvisory Agreement” and, together with the “Advisory Agreement,” the “Agreements”) between the Advisor and BlackRock Financial Management, Inc. (the “Subadvisor”). The Advisor and the Subadvisor are collectively referred to herein as the “Advisors” and, together with BlackRock, Inc., “BlackRock.”

Activities and Composition of the Board

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

Advisory Agreement and Subadvisory Agreement

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

Throughout the year, the Board also considered a range of information in connection with its oversight of the services provided by BlackRock and its affiliates. Among the matters the Board considered were: (a) investment performance for one-, three- and five-year periods, as applicable, against peer funds, as well as senior management and portfolio managers’ analysis of the reasons for underperformance, if applicable; (b) fees, including advisory, administration and other fees paid to BlackRock and its affiliates by each Fund, as applicable; (c) Fund operating expenses paid to third parties; (d) the resources devoted to and compliance reports relating to each Fund’s investment objective, policies and restrictions; (e) each Fund’s compliance with its Code of Ethics and compliance policies and procedures; (f) the nature, cost and character of non-investment management services provided by BlackRock and its affiliates; (g) BlackRock’s and other service providers’ internal controls; (h) BlackRock’s implementation of the proxy voting guidelines approved by the Board; (i) execution quality; (j) valuation and liquidity procedures; and (k) reviews of BlackRock’s business, including BlackRock’s response to the increasing scale of its business.

Board Considerations in Approving the Advisory Agreement and Subadvisory Agreement

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

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

In addition to the foregoing materials, independent legal counsel to the Independent Trustees provided a legal memorandum outlining, among other things, the duties of the Board under the 1940 Act, as well as the general principles of relevant law in reviewing and approving advisory contracts, the requirements of the 1940 Act in such matters, an adviser’s fiduciary duty with respect to advisory agreements and compensation, and the standards used by courts in determining whether investment company boards of directors have fulfilled their duties and the factors to be considered by boards in voting on advisory agreements.




38	SEMI-ANNUAL REPORT	JUNE 30, 2008

Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued)

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

Matters Considered by the Board

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

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

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

B. The Investment Performance of the Funds and BlackRock: As previously noted, the Board received performance information regarding each Fund and its Peers. Among other things, the Board received materials reflecting each Fund’s historic performance and each Fund’s performance compared to its Peers. More specifically, each Fund’s one-, three- and five-year total returns (as applicable) were evaluated relative to its Peers (including the Peers’ median performance).

The Board reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock, which analyzed various factors that affect Lipper rankings.

The Board noted that in general HIS performed better than its Peers in that the Fund’s performance was at or above the median in at least two of the one-, three- and five-year periods reported.

The Board noted that in general BPP and BGT performed better than their respective Peers in that each Fund’s performance was at or above the median of its respective Peers in at least two of the one-year, three-year and since inception periods reported.

After considering this information, the Boards concluded that the performance of each Fund, in light of and after considering the other facts and circumstances applicable to each Fund, supports a conclusion that each Fund’s Agreements should be renewed.

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

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

The Board noted that, although HIS paid contractual management fees higher than the median of its Peers, such fees were no more than 5 basis points greater than the median amount and therefore considered not to be materially higher than its Peers. This comparison was made without giving effect to any expense reimbursements or fee waivers.




SEMI-ANNUAL REPORT	JUNE 30, 2008	39

Disclosure of Investment Advisory Agreement and Subadvisory Agreement (concluded)

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

In connection with the Board’s consideration of the fees and expense information, the Board reviewed the considerable investment management experience of the Advisors and considered the high level of investment management, administrative and other services provided by the Advisors. In light of these factors and the other facts and circumstances applicable to each Fund, the Board concluded that the fees paid and level of expenses incurred by each Fund under its Agreements support a conclusion that each Fund’s Agreements should be renewed.

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

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

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

The Board concluded that BlackRock’s profitability, in light of all the other facts and circumstances applicable to each Fund, supports a conclusion that each Fund’s Agreements should be renewed.

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

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

Conclusion with Respect to the Agreements

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

Availability of Quarterly Schedule of Investments

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

Information on the operation of the Public Reference Room may be obtained by calling (800) SEC-0330. Each Trust’s Forms N-Q may also be obtained upon request and without charge by calling (800) 441-7762.

Electronic Delivery

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

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

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

General Information

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

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