Dear Shareholder Time and again, we have seen how various global events and developing trends can have significant influence on financial markets. I hope you find that the following review of recent market conditions provides additional perspective on the performance of your investments as you read this shareholder report. Over the past 12 months, we have seen a sluggish, stimulus-driven economic recovery at long last gain real traction, accelerate, and transition into a consumption-driven expansion. For the most part, 2010 was plagued with widely fluctuating economic data, but as the year drew to a close, it became clear that cyclical stimulus had beaten out structural problems as economic data releases generally became more positive and financial markets showed signs of continuing improvement. Although the sovereign debt crisis in Europe and high inflation in developing markets that troubled the global economy in 2010 remain challenges today, overall investor confidence has improved considerably. During the first four months of 2011, that confidence was shaken by political turmoil in the Middle East/North Africa region, soaring prices of oil and other commodities, tremendous natural disasters in Japan and a change in the ratings outlook for US debt. However, strong corporate earnings prevailed and financial markets resumed their course while the global economy continued to garner strength. Equity markets experienced uneven growth and high volatility in 2010, but ended the year with gains. Following a strong start to 2011, the series of confi- dence-shaking events brought spurts of heightened volatility to markets worldwide, but was not enough to derail the bull market. Overall, global equities posted strong returns over the past 12 months. Emerging market equities, which had outperformed developed markets earlier in the period, fell prey to heightened inflationary pressures and underperformed developed markets later in the period. In the United States, strong corporate earnings and positive signals from the labor market were sources of encouragement for equity investors, although the housing market did not budge from its slump. Early in 2011, the US Federal Reserve announced that it would continue its Treasury purchase program (“QE2”) through to completion and keep interest rates low for an extended period. This compelled investors to continue buying riskier assets, furthering the trend of small cap stocks outperforming large caps. While fixed income markets saw yields trend lower (pushing bond prices higher) through most of 2010, the abrupt reversal in investor sentiment and risk tolerance in the fourth quarter drove yields sharply upward. Global credit markets were surprisingly resilient in the face of recent headwinds and yields regained relative stability as the period came to a close. Yield curves globally remained steep by historical standards and higher-risk sectors continued to outperform higher-quality assets. The tax-exempt municipal market enjoyed a powerful rally during the period of low yields in 2010, but when that trend reversed, the market was dealt an additional blow as it became evident that the Build America Bond program would not be extended. Meanwhile, municipal finance troubles raised credit concerns among investors and tax-exempt mutual funds experienced heavy outflows, resulting in wider spreads and falling prices. The new year brought relief from these headwinds and a steady rebound in the tax-exempt municipal market. Cash investments, as represented by the 3-month Treasury bill, returned only a fraction over 0% for the 12-month period as short-term interest rates remained low. Yields on money market securities remain near all-time lows.

Risk Assets Rallied on Growing Investor Confidence: Total Returns as of April 30, 2011 6-month 12-month
US large cap equities (S&P 500 ® Index) 16.36% 17.22%

Fund Summary as of April 30, 2011 BlackRock Credit Allocation Income Trust I, Inc. Fund Overview BlackRock Credit Allocation Income Trust I, Inc.’s (PSW) (the “Fund”) primary investment objective is to provide holders of common shares (“Common Shareholders”) with high current income. The secondary investment objective of the Fund is to provide Common Shareholders with capital appreciation. The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its assets in credit-related securities, including, but not limited to, investment grade corporate bonds, high yield bonds (commonly referred to as “junk” bonds), bank loans, preferred securities or convertible bonds or derivatives with economic characteristics similar to these credit-related securities. The Fund may invest directly in such securities or synthetically through the use of derivatives. No assurance can be given that the Fund’s investment objective will be achieved.

Portfolio Management Commentary How did the Fund perform? • For the six months ended April 30, 2011, the Fund returned (0.82)% based on market price and 3.73% based on net asset value (“NAV”). For the same period, the closed-end Lipper Corporate Debt Funds (BBB-Rated) category posted an average return of (0.45)% based on market price and 2.46% based on NAV. All returns reflect reinvestment of dividends. The Fund's discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The following discussion relates to performance based on NAV. What factors influenced performance? • The primary driver of the Fund’s positive performance was its allocation to high yield corporate credit, as the sector broadly rallied during the period on improving fundamentals and continued signs of economic recovery in the United States. Also contributing positively was the Fund’s allocation and security selection within investment grade corpo- rate credit. In particular, an allocation to capital securities, including trust preferreds and hybrid securities, had a positive impact due to a technical rally in that space sparked by the favorable outcome of finan- cial regulatory reform. Within the industrials sector, the Fund’s prefer- ence for media cable and media non-cable as well as wireless names boosted returns as these industries performed well during the period. The Fund also benefited from reducing its portfolio duration (sensitivity to interest rates) in the first half of the period, as interest rates rose fol- lowing the announcement from the US Federal Reserve that it would implement a second round of quantitative easing.

• Conversely, the Fund’s shorter duration bias hurt performance in the later half of the period when interest rates turned lower on rising oil prices and the disastrous earthquake in Japan. In addition, as the yield curve steepened near the end of 2010 and into early 2011, the Fund’s yield curve-flattening bias (fewer holdings of short-dated bonds in favor of longer-dated bonds) detracted from performance. Lastly, the Fund’s financials and utilities holdings had a negative impact as both sectors underperformed for the six-month period. Describe recent portfolio activity. • During the six-month period, the Fund increased exposure to high yield corporate credit in order to position itself to benefit from the positive effects of an accommodative monetary policy fueling an economic recovery and improving corporate fundamentals. Describe Fund positioning at period end. • The Fund maintained diversified exposure across investment grade and high yield corporate credits with a quality bias toward lower-quality investment grade issues. The Fund ended the period with a smaller allocation to financials in favor of the industrials and utilities sectors, and a relatively short duration bias.

What factors influenced performance? • The main driver of positive performance for the period was the Fund’s allocation (approximately 10% of the portfolio) to high yield bonds, as the asset class outperformed Floating Rate Loan Interests (bank loans). In addition, the Fund maintained its level of leverage at or above the Lipper category average, which benefited the Fund’s performance rela- tive to its peer group competitors that do not employ leverage, as would be expected when markets are advancing. • As a matter of investment style, the Fund holds a considerable alloca- tion to foreign bonds (approximately 30% of the portfolio). Many of those non-US issuers have investment grade credit quality ratings, such as Gazprom (Russia), which underperformed the Fund’s high yield bond holdings. • The Fund uses foreign currency exchange contracts to manage currency risk in the portfolio. The net effect of the contracts duing the period was negative.

Describe recent portfolio activity. • During the six-month period, the Fund decreased its exposure to higher- quality high yield credits and increased exposure to high yield credits with mid-range quality ratings as the economy gradually expanded and a robust new-issue market provided greater access to attractive oppor- tunities. Relative to its competitors, the Fund continues to maintain a bias towards higher-quality and more liquid borrowers, sectors and loan structures, particularly as loan prices generally are approaching par. Describe Fund positioning at period end. • At period end, the Fund held 85% of its total portfolio in bank loans and 15% in fixed-rate bonds, primarily high yield, with the remainder invested in a mix of convertible bonds, preferred securities, equities and cash. The Fund ended the period with leverage at approximately 31% of its total managed assets.

The Benefits and Risks of Leveraging The Funds may utilize leverage to seek to enhance the yield and NAV of their common shares (“Common Shares”). However, these objectives cannot be achieved in all interest rate environments. The Funds may utilize leverage by borrowing through a credit facility or entering into reverse repurchase agreements. PSW, PSY, BPP, BTZ and BGT had auction market preferred shares (“Preferred Shares”) issuances out- standing during the six-month period ended April 30, 2011. In general, the concept of leveraging is based on the premise that the cost of assets to be obtained from leverage, which will be based on short-term interest rates, will normally be lower than the income earned by each Fund on its longer-term portfolio investments. To the extent that the total assets of each Fund (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, each Fund’s Common Shareholders will benefit from the incremental net income. The interest earned on securities purchased with the proceeds from lever- age is paid to Common Shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the per share NAV of each Fund’s Common Shares. However, in order to benefit Common Shareholders, the yield curve must be positively sloped; that is, short-term interest rates must be lower than long-term interest rates. If the yield curve becomes negatively sloped, meaning short-term interest rates exceed long-term interest rates, income to Common Shareholders will be lower than if the Funds had not used leverage. To illustrate these concepts, assume a Fund’s capitalization is $100 million and it borrows an additional $30 million, creating a total value of $130 mil- lion available for investment in long-term securities. If prevailing short-term interest rates are 3% and long-term interest rates are 6%, the yield curve has a strongly positive slope. In this case, the Fund pays borrowing cost and interest expense on the $30 million of borrowings based on the lower short- term interest rates. At the same time, the securities purchased by the Fund with assets received from the borrowings earn income based on long-term interest rates. In this case, the borrowing cost and interest expense of the borrowings is significantly lower than the income earned on the Fund’s long-term investments, and therefore the Common Shareholders are the beneficiaries of the incremental net income. If short-term interest rates rise, narrowing the differential between short- term and long-term interest rates, the incremental net income pickup on the Common Shares will be reduced or eliminated completely. Furthermore, if prevailing short-term interest rates rise above long-term interest rates of 6%, the yield curve has a negative slope. In this case, the Fund pays divi- dends on the higher short-term interest rates whereas the Fund’s total portfolio earns income based on lower long-term interest rates.

Furthermore, the value of a Fund’s portfolio investments generally varies inversely with the direction of long-term interest rates, although other factors can influence the value of portfolio investments. In contrast, the redemption value of the Funds’ borrowings does not fluctuate in relation to interest rates. As a result, changes in interest rates can influence each Fund’s NAV positively or negatively in addition to the impact on Fund performance from leverage and borrowings discussed above. The use of leverage may enhance opportunities for increased income to the Funds and Common Shareholders, but as described above, it also creates risks as short or long-term interest rates fluctuate. Leverage also will gener- ally cause greater changes in the Funds’ NAVs, market prices and dividend rates than comparable portfolios without leverage. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, each Fund’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 Fund’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. Each Fund may be required to sell portfolio securities at inopportune times or at distressed values in order to comply with regulatory requirements applicable to the use of leverage or as required by the terms of leverage instruments which may cause a Fund to incur losses. The use of leverage may limit each Fund’s abil- ity to invest in certain types of securities or use certain types of hedging strategies. Each Fund will incur expenses in connection with the use of leverage, all of which are borne by Common Shareholders and may reduce income to the Common Shares. Under the Investment Company Act of 1940, each Fund is permitted to bor- row up to 33 1 / 3 % of its total managed assets. Under normal circumstances, each Fund anticipates that the total economic leverage from reverse repur- chase agreements and credit facility borrowings will not exceed 33 1 / 3 % of its total managed assets at the time such leverage is incurred. As of April 30, 2011, the Funds had economic leverage from reverse repurchase agree- ments and/or credit facility borrowings as a percentage of their total man- aged assets as follows:

Percent of
Leverage
PSW 25%
PSY 25%
BPP 19%
BTZ 21%
BGT 31%

Derivative Financial Instruments The Funds may invest in various derivative financial instruments, including financial futures contracts, swaps, options and foreign currency exchange contracts, as specified in Note 2 of the Notes to Financial Statements, which may constitute forms of economic leverage. Such instruments are used to obtain exposure to a market without owning or taking physical cus- tody of securities or to hedge market, equity, credit, foreign currency exchange rate, interest rate and/or other risks. Such derivative financial instruments involve risks, including the imperfect correlation between the value of a derivative instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the derivative instru - ment. The Funds’ ability to use a derivative instrument successfully depends on the investment advisor’s ability to predict pertinent market movements accurately, which cannot be assured. The use of derivative financial instruments may result in losses greater than if they had not been used, may require a Fund to sell or purchase portfolio investments at inop- portune times or for distressed values, may limit the amount of apprecia- tion a Fund can realize on an investment, may result in lower dividends paid to shareholders or may cause a Fund to hold an investment that it might otherwise sell. The Funds’ investments in these instruments are dis- cussed in detail in the Notes to Financial Statements.

• Fair Value Measurements — Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs are summarized in three broad levels for financial statement purposes as follows: • Level 1 — price quotations in active markets/exchanges for identical assets and liabilities • Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs) • Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments and derivative financial instruments) The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and derivative financial instruments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

The following tables summarize the inputs used as of April 30, 2011 in determining the fair valuation of the Fund’s investments and derivative financial instruments:

• Fair Value Measurements — Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs are summarized in three broad levels for financial statement purposes as follows: • Level 1 — price quotations in active markets/exchanges for identical assets and liabilities • Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs) • Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments and derivative financial instruments) The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and derivative financial instruments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements. The following tables summarize the inputs used as of April 30, 2011 in determining the fair valuation of the Fund’s investments and derivative financial instruments:

• Fair Value Measurements — Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs are summarized in three broad levels for financial statement purposes as follows: • Level 1 — price quotations in active markets/exchanges for identical assets and liabilities • Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for iden- tical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs) • Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments and derivative financial instruments) The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and derivative financial instruments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements. The following tables summarize the inputs used as of April 30, 2011 in determining the fair valuation of the Fund’s investments and derivative financial instruments:

investments and derivative financial instruments. These inputs are summarized in
three broad levels for financial statement purposes as follows:
• Level 1 — price quotations in active markets/exchanges for identical assets
and liabilities
• Level 2 — other observable inputs (including, but not limited to: quoted prices for
similar assets or liabilities in markets that are active, quoted prices for identical
or similar assets or liabilities in markets that are not active, inputs other than
quoted prices that are observable for the assets or liabilities (such as interest
rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and
default rates) or other market-corroborated inputs)
• Level 3 — unobservable inputs based on the best information available in the
circumstances, to the extent observable inputs are not available (including the
Fund’s own assumptions used in determining the fair value of investments and
derivative financial instruments)
The inputs or methodologies used for valuing securities are not necessarily an
indication of the risk associated with investing in those securities. For information
about the Fund’s policy regarding valuation of investments and derivative financial
instruments and other significant accounting policies, please refer to Note 1 of the
Notes to Financial Statements.

• Fair Value Measurements — Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs are summarized in three broad levels for financial statement purposes as follows: • Level 1 — price quotations in active markets/exchanges for identical assets and liabilities • Level 2 — other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs) • Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments and derivative financial instruments) The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and derivative financial instruments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

Notes to Financial Statements (Unaudited) 1. Organization and Significant Accounting Policies: BlackRock Credit Allocation Income Trust I, Inc. (“PSW”) and BlackRock Credit Allocation Income Trust II, Inc. (“PSY”) are registered as diversified, closed-end management investment companies under the Investment Company Act of 1940, as amended (the “1940 Act”). BlackRock Credit Allocation Income Trust III (“BPP”), BlackRock Credit Allocation Income Trust IV (“BTZ”) and BlackRock Floating Rate Income Trust (“BGT”) are registered as non-diversified, closed-end management investment companies under the 1940 Act. PSW and PSY are organized as Maryland corporations. BPP, BTZ and BGT are organized as Delaware statutory trusts. PSW, PSY, BPP, BTZ and BGT are collectively referred to as the “Funds” or individually as the “Fund.” The Funds’ financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”), which may require management to make estimates and assumptions that affect the reported amounts and disclosure in the finan- cial statements. Actual results could differ from these estimates. The Board of Directors and Board of Trustees of the Funds, as applicable, are referred to throughout this report as the “Board of Directors” or the “Board.” The Funds determine and make available for publication the net asset values of their Common Shares on a daily basis. The following is a summary of significant accounting policies followed by the Funds: Valuation: US GAAP defines fair value as the price the Funds would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Funds fair value their financial instruments at market value using independent dealers or pricing services under policies approved by the Board. Floating rate loan interests are valued at the mean of the bid prices from one or more brokers or dealers as obtained from a pricing service. In determining the value of a particular investment, pricing services may use certain informa- tion 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. Financial futures contracts traded on exchanges are valued at their last sale price. Swap agreements are valued utilizing quotes received daily by the Funds’ pricing service or through brokers, which are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows and trades and values of the underlying reference instruments. Investments in open- end investment companies are valued at net asset value each business day. Short-term securities with remaining maturities of 60 days or less may be valued at amortized cost, which approximates fair value. Equity investments traded on a recognized securities exchange or the NASDAQ Global Market System (“NASDAQ”) are valued at the last reported sale price that day or the NASDAQ official closing price, if applicable. For equity investments traded on more than one exchange, the last reported sale price on the exchange where the stock is primarily traded is used. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last available bid (long positions) or ask (short positions) price. If no bid or ask price is available, the prior day’s price will be used, unless it is determined that such prior day’s price no longer reflects the fair value of the security.

Securities and other assets and liabilities denominated in foreign curren- cies are translated into US dollars using exchange rates determined as of the close of business on the New York Stock Exchange (“NYSE”). Foreign currency exchange contracts are valued at the mean between the bid and ask prices and are determined as of the close of business on the NYSE. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available. Exchange-traded options are valued at the mean between the last bid and ask prices at the close of the options market in which the options trade. An exchange-traded option for which there is no mean price is valued at the last bid (long positions) or ask (short positions) price. If no bid or ask price is available, the prior day’s price will be used, unless it is determined that the prior day’s price no longer reflects the fair value of the option. Over-the- counter (“OTC”) options and swaptions are valued by an independent pricing service using a mathematical model which incorporates a number of market data factors, such as the trades and prices of the underlying instruments. In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the market value of such investment or is not available, the investment will be valued in accordance with a policy approved by the Board as reflecting fair value (“Fair Value Assets”). When determining the price for Fair Value Assets, the investment advisor and/or the sub-advisor seeks to determine the price that each Fund might reasonably expect to receive from the cur- rent sale of that asset in an arm’s-length transaction. Fair value determina- tions shall be based upon all available factors that the investment advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof. Generally, trading in foreign instruments is substantially completed each day at various times prior to the close of business on the NYSE. Occasionally, events affecting the values of such instruments may occur between the foreign market close and the close of business on the NYSE that may not be reflected in the computation of each Fund’s net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such instruments, those instruments may be Fair Value Assets and be valued at their fair value, as determined in good faith by the investment advisor using a pricing service and/or policies approved by the Board. Each business day, the Funds use a pricing service to assist with the valuation of certain foreign exchange-traded equity securities and foreign exchange-traded and OTC options (the “Systematic Fair Value Price”). Using current market factors, the Systematic Fair Value Price is designed to value such foreign securities and foreign options at fair value as of the close of business on the NYSE, which follows the close of the local markets. Foreign Currency Transactions: The Funds’ books and records are main- tained in US dollars. Purchases and sales of investment securities are recorded at the rates of exchange prevailing on the date the transactions are entered into. Generally, when the US dollar rises in value against a foreign currency, the Funds’ investments denominated in that currency will

SEMI-ANNUAL REPORT APRIL 30, 2011 59

Notes to Financial Statements (continued) lose value because its currency is worth fewer US dollars; the opposite effect occurs if the US dollar falls in relative value. The Funds report realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are treated as ordinary income for federal income tax purposes. Zero-Coupon Bonds: The Funds may invest in zero-coupon bonds, which are normally issued at a significant discount from face value and do not provide for periodic interest payments. Zero-coupon bonds may experience greater volatility in market value than similar maturity debt obligations which provide for regular interest payments. Capital Trusts: The Funds may invest in capital trusts. These securities are typically issued by corporations, generally in the form of interest-bearing notes with preferred securities characteristics, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The securities can be structured as either fixed or adjustable coupon securities that can have either a perpetual or stated maturity date. Dividends can be deferred without creating an event of default or acceleration, although maturity cannot take place unless all cumulative payment obligations have been met. The deferral of payments does not affect the purchase or sale of these securities in the open market. Payments on these securities are treated as interest rather than dividends for federal income tax purposes. These securities generally are rated below that of the issuing company’s senior debt securities. Preferred Stock: The Funds may invest in preferred stocks. Preferred stock has a preference over common stock in liquidation (and generally in receiv- ing 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 pre- ferred 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 pay- ments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions. Floating Rate Loan Interests: The Funds may invest in floating rate loan interests. The floating rate loan interests the Funds hold are typically issued to companies (the “borrower”) by banks, other financial institutions, and privately and publicly offered corporations (the “lender”). Floating rate loan interests are generally non-investment grade, often involve borrowers whose financial condition is troubled or uncertain and companies that are highly levered. The Funds may invest in obligations of borrowers who are in bankruptcy proceedings. Floating rate loan interests may include fully funded term loans or revolving lines of credit. Floating rate loan interests are typically senior in the corporate capital structure of the borrower. Floating rate loan interests 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 the lending rate offered by one or more European banks, such as LIBOR (London Inter Bank Offered Rate), the prime rate offered by one or more US banks or the certificate of deposit rate. Floating rate loan interests may involve foreign borrowers, and investments may be denominated in foreign currencies. The Funds consider these investments to be investments in debt securities for purposes of their investment policies. When a Fund buys a floating rate loan interest it may receive a facility fee and when it sells a floating rate loan interest it may pay a facility fee. On an ongoing basis, the Funds may receive a commitment fee based on the undrawn portion of the underlying line of credit amount of a floating rate loan interest. The Funds earn and/or pays facility and other fees on floating rate loan interests, which are shown as facility and other fees in the Statements of Operations. Facility and commitment fees are typically amortized to income over the term of the loan or term of the commitment, respectively. Consent and amendment fees are recorded to income as earned. Prepayment penalty fees, which may be received by the Funds upon the prepayment of a floating rate loan interest by a borrower, are recorded as realized gains. The Funds 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 loan interests are usually freely callable at the borrower’s option. The Funds may invest in such loans in the form of participations in loans (“Participations”) or assignments (“Assignments”) of all or a portion of loans from third parties. Participations typically will result in the Funds having a contractual relationship only with the lender, not with the borrower. The Funds 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 Funds generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights of offset against the borrower, and the Funds may not benefit directly from any collateral supporting the loan in which it has purchased the Participation. As a result, the Funds will assume the credit risk of both the borrower and the lender that is selling the Participation. The Funds’ investment in loan participation interests involves 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 Funds may be treated as general creditors of the lender and may not benefit from any offset between the lender and the borrower. Assignments typically result in the Funds having a direct contractual relationship with the borrower, and the Funds may enforce compliance by the borrower with the terms of the loan agreement. Reverse Repurchase Agreements: The Funds may enter into reverse repurchase agreements with qualified third party broker-dealers. In a reverse repurchase agreement, the Funds sell securities to a bank or broker-dealer and agrees to repurchase the same securities at a mutually agreed upon date and price. Certain agreements have no stated maturity and can be terminated by either party at any time. Interest on the value of

60 SEMI-ANNUAL REPORT APRIL 30, 2011

$$/page=

Notes to Financial Statements (continued) the reverse repurchase agreements issued and outstanding is based upon competitive market rates determined at the time of issuance. The Funds may utilize reverse repurchase agreements when it is anticipated that the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities that the Funds are obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Funds’ use of the proceeds of the agreement may be restricted while the other party, or its trustee or receiver, determines whether or not to enforce the Funds’ obligation to repurchase the securities. Defensive Positions: PSW, PSY, BPP and BTZ Fund may vary its investment policies for temporary defensive purposes during periods in which the investment advisor believes that conditions in the securities markets or other economic, financial or political conditions warrant. Under such conditions, the Funds for temporary defensive purposes may invest up to 100% of its total assets in, as applicable and described in each Fund’s prospectus, US government securities, certificates of deposit, repurchase agreements that involve purchases of debt securities, bankers’ acceptances and other bank obligations, commercial paper, money market funds and/or other debt securities deemed by the investment advisor to be consistent with a defensive posture, or may hold its assets in cash. Segregation and Collateralization: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission (“SEC”) require that the Funds either deliver collateral or segregate assets in connection with certain investments (e.g., financial futures contracts, foreign currency exchange contracts and swaps), or certain borrowings (e.g., reverse repurchase agreements and loan payable), the Funds will, consistent with SEC rules and/or certain interpretive letters issued by the SEC, segregate collateral or designate on their books and records cash or other liquid securities having a market value at least equal to the amount that would otherwise be required to be physically segregated. Furthermore, based on requirements and agreements with certain exchanges and third party broker-dealers, each party has requirements to deliver/deposit securities as collateral for certain investments. Investment Transactions and Investment Income: For financial reporting purposes, investment transactions are recorded on the dates the trans- actions are entered into (the trade dates). Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Funds are informed of the ex-dividend date. Under the applicable foreign tax laws, a withholding tax at various rates may be imposed on capital gains, dividends and interest. Upon notification from issuers, some of the dividend income received from a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized on the accrual basis.

Dividends and Distributions: Dividends from net investment income are declared and paid daily. Distributions of capital gains are recorded on the ex-dividend dates. If the total dividends and distributions made in any tax year exceeds net investment income and accumulated realized capital gains, a portion of the total distribution may be treated as a tax return of capital. The amount and timing of dividends and distributions are deter- mined in accordance with federal income tax regulations, which may differ from US GAAP. Dividends and distributions to Preferred Shareholders were accrued and determined as described in Note 6. Income Taxes: It is each Fund’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. BGT has a wholly owned taxable subsidiary organized as a limited liability company (the “Taxable Subsidiary”) which holds one of the investments listed in the Schedule of Investments. The Taxable Subsidiary enables the Fund to hold an investment that is organized as an operating partnership while still satisfying Regulated Investment Company tax requirements. Income earned on the investment held by the Taxable Subsidiary is taxable to such subsidiary. An income tax provision for all income, including realized and unrealized gains, if any, of the Taxable Subsidiary is reflected in the value of the investment held by the Taxable Subsidiary. Each Fund files US federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limita- tions on PSW’s and PSY’s US federal tax returns remains open for the four years ended October 31, 2010. The statute of limitations on BPP’s and BGT’s US federal tax returns remains open for the year ended December 31, 2007, the period ended October 31, 2008 and the two years ended October 31, 2010. The statute of limitations on BTZ’s US Federal tax returns remains open for the three years ended October 31, 2010 and the period ended October 31, 2007. The statutes of limitations on the Funds’ state and local tax returns may remain open for an additional year depending upon the jurisdiction. There are no uncertain tax positions that require recognition of a tax liability. Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by each Fund’s Board, independent Directors (“Independent Directors”) may defer a portion of their annual complex-wide compensation. Deferred amounts earn an approximate return as though equivalent dollar amounts had been invested in common shares of certain other BlackRock Closed-End Funds selected by the Independent Directors. This has approximately the same economic effect for the Independent Directors as if the Independent Directors had invested the deferred amounts directly in certain other BlackRock Closed-End Funds. The deferred compensation plan is not funded and obligations there-under represent general unsecured claims against the general assets of each Fund. Each Fund may, however, elect to invest in common shares of certain other BlackRock Closed-End Funds selected by the Independent Directors

Notes to Financial Statements (continued) in order to match its deferred compensation obligations. Investments to cover each Fund’s deferred compensation liability, if any, are included in other assets in the Statements of Assets and Liabilities. Dividends and distributions from the BlackRock Closed-End Fund investments under the plan are included in income — affiliated in the Statements of Operations. Other: Expenses directly related to the Funds are charged to that Fund. Other operating expenses shared by several funds are pro rated among those funds on the basis of relative net assets or other appropriate methods. The Funds have an arrangement with the custodian whereby fees may be reduced by credits earned on uninvested cash balances, which if applicable are shown as fees paid indirectly in the Statements of Operations. The custodian imposes fees on overdrawn cash balances, which can be offset by accumulated credits earned or may result in additional custody charges. 2. Derivative Financial Instruments: The Funds engage in various portfolio investment strategies using derivative contracts both to increase the returns of the Funds and to economically hedge, or protect, their exposure to certain risks such as credit risk, equity risk, interest rate risk, foreign currency exchange rate risk or other risk (commodity price risk and inflation risk). These contracts may be trans- acted on an exchange or OTC. Losses may arise if the value of the contract decreases due to an unfavor- able change in the market rates or values of the underlying instrument or if the counterparty does not perform under the contract. The Funds’ maxi- mum risk of loss from counterparty credit risk on OTC derivatives is gener- ally the aggregate unrealized gain netted against any collateral pledged by/posted to the counterparty. For OTC options purchased, the Funds bear the risk of loss in the amount of the premiums paid plus the positive change in market values net of any collateral received on the options should the counterparty fail to perform under the contracts. Options written by the Funds do not give rise to counterparty credit risk, as options written obligate the Funds to perform and not the counterparty. Counterparty risk related to exchange-traded financial futures contracts and options is deemed to be minimal due to the protection against defaults provided by the exchange on which these contracts trade. The Funds may mitigate counterparty risk by procuring collateral and through netting provisions included within an International Swaps and Derivatives Association, Inc. (“ISDA”) Master Agreement implemented between a Fund and each of its respective counterparties. The ISDA Master Agreement allows each Fund to offset with each separate counterparty certain derivative financial instrument’s payables and/or receivables with collateral held. The amount of collateral moved to/from applicable counterparties is generally based upon minimum transfer amounts of up to $500,000. To the extent amounts due to the Funds from their counter- parties are not fully collateralized contractually or otherwise, the Funds bear the risk of loss from counterparty non-performance. See Note 1 “Segregation and Collateralization” for information with respect to collateral practices. In addition, the Funds manage counterparty risk by entering into agreements only with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Funds’ net assets decline by a stated percentage or the Funds fail to meet the terms of its ISDA Master Agreements, which would cause the Funds to accelerate payment of any net liability owed to the counterparty. Financial Futures Contracts: The Funds purchase or sell financial futures contracts and options on financial futures contracts to gain exposure to, or economically hedge against, changes in interest rates (interest rate risk), changes in the value of equity securities (equity risk) or foreign currencies (foreign currency exchange rate risk). Financial futures contracts are agree- ments between the Funds and the counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the particular contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date of by payment of a cash settlement amount on settle- ment date. Pursuant to the contract, the Funds agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as margin variation and are recorded by the Funds as unrealized appreciation or depreciation. When the contract is closed, the Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The use of financial futures contracts involves the risk of an imperfect correlation in the move- ments in the price of financial futures contracts, interest rates and the underlying assets. Foreign Currency Exchange Contracts: The Funds enter into foreign cur- rency exchange contracts as an economic hedge against either specific transactions or portfolio instruments or to obtain exposure to foreign cur- rencies (foreign currency exchange rate risk). A foreign currency exchange contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a future date. Foreign currency exchange contracts, when used by the Funds, help to manage the overall exposure to the cur- rencies, in which some of the investments held by the Funds are denomi- nated. The contract is marked-to-market daily and the change in market value is recorded by the Funds as an unrealized gain or loss. When the contract is closed, the Funds record a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. The use of foreign currency exchange contracts involves the risk that the value of a foreign currency exchange contract changes unfavorably due to movements in the value of the referenced for- eign currencies and the risk that a counterparty to the contract does not perform its obligations under the agreement. Options: The Funds purchase and write call and put options to increase or decrease their exposure to underlying instruments (including equity risk, interest rate risk and/or commodity price risk) and/or, in the case of options written, to generate gains from options premiums. A call option gives the purchaser of the option the right (but not the obligation) to buy, and obligates the seller to sell (when the option is exercised), the underlying instrument at the exercise price at any time or at a specified time during the option period. A put option gives the holder the right to sell and obligates the writer to buy the underlying instrument at the exercise

Notes to Financial Statements (continued) price at any time or at a specified time during the option period. When the Funds purchase (writes) an option, an amount equal to the premium paid (received) by the Funds is reflected as an asset (liability). The amount of the asset (liability) is subsequently marked-to-market to reflect the current market value of the option purchased (written). When an instrument is pur- chased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the instrument acquired or deducted from (or added to) the proceeds of the instrument sold. When an option expires (or the Funds enter into a closing transac- tion), the Funds realize a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premiums received or paid). When the Funds write a call option, such option is “covered,” meaning that the Funds holds the underlying instrument subject to being called by the option counterparty. When the Funds write a put option, such option is covered by cash in an amount sufficient to cover the obligation. In purchasing and writing options, the Funds bear the risk of an unfavor- able change in the value of the underlying instrument or the risk that the Funds may not be able to enter into a closing transaction due to an illiquid market. Exercise of a written option could result in the Funds purchasing or selling a security at a price different from the current market value. Swaps: The Funds enter into swap agreements, in which the Funds and a counterparty agree to make periodic net payments on a specified notional amount. These periodic payments received or made by the Funds are recorded in the Statements of Operations as realized gains or losses, respectively. Any upfront fees paid are recorded as assets and any upfront fees received are recorded as liabilities and amortized over the term of the swap. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). When the swap is ter- minated, the Funds will record a realized gain or loss equal to the differ- ence between the proceeds from (or cost of) the closing transaction and the Funds’ basis in the contract, if any. Generally, the basis of the contracts is the premium received or paid. Swap transactions involve, to varying degrees, elements of interest rate, credit and market risk in excess of the amounts recognized in the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions. • Credit default swaps — The Funds enter into credit default swaps to manage their exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults of corporate and/or sovereign issuers or to create exposure to corporate and/or sovereign issuers to which they are not otherwise exposed (credit risk). The Funds enter into credit default swap agreements to provide a measure of protection against the default of an issuer (as buyer of protection) and/or gain credit exposure to an issuer to which it is not otherwise exposed (as seller of protection). The Funds may either buy or sell (write) credit default swaps on single-name issuers (corporate or sovereign), a combination or basket of single-name issuers or traded indexes. Credit default swaps on single-name issuers are agreements in which the buyer pays fixed periodic payments to the seller in consideration for a guarantee from the seller to make a specific payment should a negative credit event take place with respect to the referenced entity (e.g., bankruptcy, failure to pay, obligation accelerators, repudiation, moratorium or restructuring). Credit default swaps on traded indexes are agreements in which the buyer pays fixed periodic payments to the seller in consideration for a guarantee from the seller to make a spe- cific payment should a write-down, principal or interest shortfall or default of all or individual underlying securities included in the index occurs. As a buyer, if an underlying credit event occurs, the Funds will either receive from the seller an amount equal to the notional amount of the swap and deliver the referenced security or underlying securities comprising the index or receive a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising the index. As a seller (writer), if an underlying credit event occurs, the Funds will either pay the buyer an amount equal to the notional amount of the swap and take delivery of the referenced security or underlying securities comprising the index or pay a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising the index.

3. Investment Advisory Agreement and Other Transactions with Affiliates: As of April 30, 2011, the PNC Financial Services Group, Inc. (“PNC”), Bank of America Corporation (“BAC”) and Barclays Bank PLC (“Barclays”) were the largest stockholders of BlackRock, Inc. (“BlackRock”). Due to the own- ership structure, PNC is an affiliate of the Funds for 1940 Act purposes, but BAC and Barclays are not. Each Fund entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Manager”), the Funds’ investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services. The Manager is responsible for the management of each Fund’s portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of each Fund. For such services, each Fund pays the Manager a monthly fee at the following annual rates of each Fund’s average daily (weekly for BPP, BTZ and BGT) net assets (including any assets attributable to borrowings or to the proceeds from the issuance of Preferred Shares) as follows:

PSW 0.60%
PSY 0.60%
BPP 0.65%
BTZ 0.65%
BGT 0.75%

Average daily net assets is the average daily value of each Fund’s total assets minus the sum of its accured liabilities (other than borrowings representing financial leverage). Average weekly net assets is the average weekly value of each Fund’s total assets minus the sum of its liabilities (other than borrowings representing financial leverage).

The Manager has voluntarily agreed to waive a portion of the investment advisory fees or other expenses on BGT as a percentage of its average weekly net assets (including any assets attributable to borrowings or to the proceeds from the issuance of Preferred Shares) minus the sum of liabilities (other than borrowings representing financial leverage) as follows: 0.10% for the period September 1, 2010 to August 31, 2011 and 0.05% for the period September 1, 2011 to August 31, 2012. For the six months ended April 30, 2011, the Manager waived $231,540, which is included in fees waived by advisor in the Statements of Operations The Manager voluntarily agreed to waive its advisory fees by the amount of investment advisory fees each Fund pays to the Manager indirectly through its investment in affiliated money market funds, however the Manager does not waive its investment advisory fees by the amount of investment advisory fees paid through each Fund’s investment in other affiliated investment companies, if any. These amounts are included in fees waived by advisor in the Statements of Operations. For the six months ended April 30, 2011, the amounts waived were as follows:

PSW $ 647
PSY $2,820
BPP $2,875
BTZ $9,161
BGT $1,378

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

Notes to Financial Statements (continued)

For the period November 1, 2010 through December 31, 2010, the Funds reimbursed the Manager for certain accounting services, which are included in accounting services in the Statements of Operations. The reimbursements were as follows:

Accounting
Services
PSW $ 228
PSY $ 1,017
BPP $ 2,822
BTZ $ 1,330
BGT $ 751

Effective January 1, 2011, the Funds no longer reimburse the Manager for accounting services. Certain officers and/or directors of the Funds are officers and/or directors of BlackRock or its affiliates. The Funds reimburse the Manager for com- pensation paid to the Funds’ Chief Compliance Officer. 4. Investments: Purchases and sales of investments including paydowns and payups, excluding short-term securities and US government securities for the six months ended April 30, 2011, were as follows:

Purchases Sales
PSW $ 47,156,602 $ 31,671,600

BPP $ 4,943,014 $ 24,571,673
BTZ $ 26,010,380 $147,075,351

5. Commitments: The Funds may invest in floating rate loan interests. In connection with these investments, the Funds may also enter into unfunded loan commit- ments (“commitments”). Commitments may obligate the Funds to furnish temporary financing to a borrower until permanent financing can be arranged. In connection with these commitments, the Funds earn a com- mitment fee, typically set as a percentage of the commitment amount. Such fee income, which is classified in the Statements of Operations as facility and other fees, is recognized ratably over the commitment period. Unfunded loan commitments are marked-to-market daily, and any unreal- ized appreciation or depreciation is included in the Statements of Assets of

Liabilities and Statements of Operations. As of April 30, 2011, BGT had the following unfunded loan commitments:

(FKA Ventive Health, Inc.) $1,066,667 $1,069,668 $ 3,001

6. Concentration, Market and Credit Risk: PSW, PSY, BPP and BTZ invest a significant portion of each of their assets in securities in the financials sector and BGT invests a significant portion of its assets in the media sector. Please see the Schedules of Investments for these securities. Changes in economic conditions affecting the financials and media sectors would have a greater impact on the Funds and could affect the value, income and/or liquidity of positions in such securities. In the normal course of business, the Funds invest in securities and enter into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations (issuer credit risk). The value of securities held by the Funds may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Funds; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to issuer credit risk, the Funds may be exposed to counterparty credit risk, or the risk that an entity with which the Funds have unsettled or open transactions may fail to or be unable to perform on its commitments. The Funds manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Funds to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Funds’ exposure to market, issuer and counterparty credit risks with respect to these financial assets is generally approximated by their value recorded in the Funds’ Statements of Assets and Liabilities, less any collateral held by the Funds. 7. Capital Share Transactions: PSW and PSY are each authorized to issue 200 million of $0.10 par value shares, all of which were initially classified as Common Shares. Each Board is authorized, however, to reclassify any unissued shares without approval of Common Shareholders. The Boards of PSW and PSY reclassified 5,460 and 22,000 unissued Common Shares as $0.10 par value Preferred Shares, respectively, none of which are outstanding. There are an unlimited number of $0.001 par value shares authorized for BPP, BTZ and BGT, which may be issued as either Common Shares or Preferred Shares.

Common Shares As of April 30, 2011, the shares owned by an affiliate of the Manager of the Funds were as follows:

Shares
PSW 8,323
PSY 8,661
BTZ 4,817
BGT 8,239

For the six months ended April 30, 2011, shares issued and outstanding increased by the following amounts as a result of dividend reinvestment:

Six Months — Ended Year Ended
April 30, October 31,
2011 2010
BGT $25,807 $32,177

Shares issued and outstanding for the six months ended April 30, 2011 and the year ended October 31, 2010 remained constant for PSW, PSY, BPP and BTZ, respectively. Preferred Shares The Preferred Shares were redeemable at the option of each Fund, in whole or in part, on any dividend payment date at their liquidation prefer- ence per share plus any accumulated and unpaid dividends whether or not declared. The Preferred Shares were also subject to mandatory redemption at their liquidation preference plus any accumulated and unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of a Fund, as set forth in each Fund’s Articles Supplementary/Statement of Preferences and/or Certificate of Designation (the “Governing Instrument”) were not satisfied. The holders of Preferred Shares had voting rights equal to the holders of Common Shares (one vote per share) and would vote together with holders of Common Shares (one vote per share) as a single class. However, the holders of Preferred Shares, voting as a separate class, were also entitled to elect two Directors for each Fund. In addition, the 1940 Act requires that along with approval by shareholders that might otherwise be required, the approval of the holders of a majority of any outstanding Preferred Shares, voting separately as a class would be required to (a) adopt any plan of reorganization that would adversely affect the Preferred Shares, (b) change a Fund’s sub-classification as a closed-end investment company or change its fundamental investment restrictions or (c) change its business so as to cease to be an investment company. Dividends on seven-day and 28-day Preferred Shares were cumulative at a rate which is reset every seven or 28 days, respectively, based on the results of an auction. If the Preferred Shares failed to clear the auction on an auction date, each Fund was required to pay the maximum applicable rate on the Preferred Shares to holders of such shares for successive divi- dend periods until such time as the shares were successfully auctioned.

The maximum applicable rate on the Preferred Shares at the last auction date was as follows: for PSW, PSY and BGT, the higher of 125% times or 1.25% plus the Telerate/BBA LIBOR rate; or BPP 150% of the interest equivalent of the 30-day commercial paper rate and for BTZ, the higher of 150% times or 1.25% plus the Telerate/BBA LIBOR rate. The low, high and average dividend rates for the six months ended April 30, 2011, were as follows:

Series Low High Average
PSW M7 1.50% 1.50% 1.50%
T7 1.50% 1.50% 1.50%

W7 1.50% 1.50% 1.50%
R7 1.50% 1.50% 1.50%

Since February 13, 2008, the Preferred Shares of the Funds failed to clear any of their auctions. As a result, the Preferred Shares dividend rates were reset to the maximum applicable rate, which ranged from 0.35% to 1.94%. A failed auction is not an event of default for the Funds but it has a nega- tive impact on the liquidity of Preferred Shares. A failed auction occurs when there are more sellers of a Fund’s auction rate preferred shares than buyers. The Funds paid commissions of 0.15% on the aggregate principal amount of all shares that failed to clear their auctions and 0.25% on the aggregate principal amount of all shares that successfully cleared their auctions. Certain broker dealers had individually agreed to reduce commissions for failed auctions.

All of the Funds, except BGT, financed the Preferred Share redemptions with cash received from reverse repurchase agreements. BGT financed the Preferred Share redemption with cash received from a loan.

8. Borrowings: BGT entered into a senior committed secured, 364-day revolving line of credit and a separate security agreement (the “SSB Agreement”) with State Street Bank and Trust Company (“SSB”). The SSB Agreement provides the Fund with a maximum commitment of $172.2 million. The Fund has granted a security interest in substantially all of its assets to SSB.

Advances are made by SSB to the Fund, at the Fund’s option of (a) the higher of (i) 0.8% above the Fed Effective Rate and (ii) 0.8% above the Overnight LIBOR or (b) 0.8% above 7-day, 30-day, 60-day or 90-day LIBOR. In addition, the Fund pays a facility fee and a commitment fee based upon SSB’s total commitment to the Fund. The fees associated with each of the agreements are included in the Statements of Operations as borrowing costs. Advances to the Fund as of April 30, 2011 are shown in the Statements of Assets and Liabilities as loan payable. The SSB Agreement was renewed for 364 days under substantially the same terms effective March 3, 2011. The commitment amount was increased from $134 million to $172.2 million. For the six months ended April 30, 2011, the daily weighted average interest rate was 1.14%. BGT may not declare dividends or make other distributions on shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding short-term borrowings is less than 300%. For the six months ended April 30, 2011, the daily weighted average inter- est rates for Funds with reverse repurchase agreements were as follows:

PSW 0.39%
PSY 0.17%
BPP 0.35%
BTZ 0.37%

Additional Information Dividend Policy The Funds’ dividend policy is to distribute all or a portion of their net investment income to their shareholders on a monthly basis. In order to provide shareholders with a more stable level of dividend distributions, the Funds may at times pay out less than the entire amount of net investment income earned in any particular month and may at times in any particular month pay out such accumulated but undistributed income in addition to net investment income earned in that month. As a result, the dividends paid by the Funds for any particular month may be more or less than the amount of net investment income earned by the Funds during such month. The Funds’ current accumulated but undistributed net investment income, if any, is disclosed in the Statements of Assets and Liabilities, which com- prises part of the financial information included in this report.

General Information On July 29, 2010, the Manager announced that a derivative complaint had been filed by shareholders of PSY and BTZ on July 27, 2010 in the Supreme Court of the State of New York, New York County. The complaint names the Manager, BlackRock, Inc. and certain of the directors, officers and portfolio managers of PSY and BTZ as defendants. The complaint alleges, among other things, that the parties named in the complaint breached fiduciary duties owed to PSY and BTZ and their Common Shareholders by redeeming auction-market preferred shares, auction rate preferred securities, auction preferred shares and auction rate securi- ties (collectively, “AMPS”) at their liquidation preference. The complaint seeks unspecified damages for losses purportedly suffered by PSY and BTZ as a result of the prior redemptions and injunctive relief preventing PSY and BTZ from redeeming AMPS at their liquidation preference in the future. The Manager, BlackRock, Inc. and the other parties named in the complaint believe that the claims asserted in the complaint are without merit and intend to vigorously defend themselves in the litigation. On November 15, 2010, the Manager announced the intention to redeem all of the outstanding AMPS issued by five of its taxable closed-end funds: PSW, PSY, BPP, BTZ, and BGT. All such outstanding AMPS were subsequently redeemed. The redemptions encompass all remaining taxable AMPS issued by BlackRock closed-end funds and total approximately $569 million. The AMPS were redeemed with available cash or proceeds from reverse repur- chase agreement financing or a credit facility on a fund-by-fund basis and, in each case, the refinancing resulted in a lower cost of financing for each fund under then-existing market conditions. In exchange for the shareholder plaintiff's agreement to withdraw a previously filed motion for preliminary injunction enjoining any further redemptions of AMPS, each of these funds agreed to provide the plaintiffs in those actions with 30 days prior notice of any additional redemptions.

On November 24, 2010, the Manager announced that counsel for the plaintiffs filed a motion for a preliminary injunction enjoining PSY and BTZ from redeeming outstanding AMPS pending final resolution of the underly- ing shareholder derivative suit. The Manager announced that it intends to vigorously oppose the motion and completed the redemption of AMPS by PSY and BTZ as previously announced, although the redemption dates for BTZ and PSY were conditioned upon the absence of any legal impediments to completing the redemptions as scheduled. The Funds do not make available copies of their Statements of Additional Information because the Funds’ shares are not continuously offered, which means that the Statement of Additional Information of each Fund has not been updated after completion of the respective Fund’s offerings and the information contained in each Fund’s Statement of Additional Information may have become outdated. During the period, there were no material changes in the Funds’ investment objectives or policies or to the Funds’ charter or by-laws that would delay or prevent a change of control of the Funds that were not approved by share- holders or in the principal risk factors associated with investment in the Funds. Other than as disclosed on page 70, there have been no changes in the persons who are primarily responsible for the day-to-day management of the Funds’ portfolio. Quarterly performance, semi-annual and annual reports and other informa- tion regarding the Funds 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 regard- ing the Funds and does not, and is not intended to, incorporate BlackRock’s website into this report.

Additional Information (continued) Section 19(a) Notices These reported amounts and sources of distributions are estimates and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon each Fund’s investment experience during the year and may be subject to changes based on the tax regula- tions. Each Fund will provide a Form 1099-DIV each calendar year that will explain the character of these dividends and distributions for federal income tax purposes.

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