2 SEMI-ANNUAL REPORT JANUARY 31, 2011

Dear Shareholder

Economic data fluctuated widely throughout 2010, 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. The sovereign debt crises and emerging market inflation that troubled the global economy in 2010 remain a challenge to global growth, but overall levels of uncertainty are gradually declining as the United States and the world economy are progressing from a stimulus-driven recovery into a consumption-driven expansion.

In the United States, the corporate sector has been an important area of strength and consumer spending has shown improvement, although weakness in the housing and labor markets continues to burden the economy. It is important to note that we are in the midst of the first global economic recovery that is being led by emerging economies, and the United States has only just begun its transition to a self-sustaining expansion, suggesting that economic improvements still have a way to go.

Global equity markets experienced uneven growth and high volatility over the course of 2010, but ended the year strong. Stocks continued their advance through most of January until the political unrest in Egypt and widespread discord across the Middle East caused a sharp, but temporary decline at the end of the period. US stocks outpaced most international markets over the 12-month period. Small cap stocks outperformed large caps as investors moved into higher-risk assets.

Fixed income markets saw yields trend lower over most of 2010, until the fourth quarter brought an abrupt reversal in sentiment and risk tolerance that drove yields sharply upward (pushing prices downward) through year end and into the New Year. However, on a 12-month basis, yields were lower overall and fixed income markets performed well. Conversely, the tax-exempt municipal market was dealt an additional blow as it became evident that the Build America Bond program would expire at the end of 2010. In addition, negative headlines regarding fiscal challenges faced by state and local governments damaged investor confidence and sparked additional volatility in the municipal market. These conditions began to moderate as the period came to a close and the market has shown signs of improvement in supply-and-demand technicals.

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.

Total Returns as of January 31, 2011	6-month			12-month
US large cap equities (S&P 500 Index)		17.93	%		22.19	%
US small cap equities (Russell 2000 Index)		20.75			31.36
International equities (MSCI Europe, Australasia, Far East Index)		16.10			15.38

Municipal Market Overview

As of January 31, 2011

The municipal market began the period with a strong tone as rates fell (and prices rose) along with those of US Treasuries. However, the cliché of the “perfect storm” of negative events all conspired in the final months of 2010, leading to the worst quarterly performance for the municipal market since the tightening cycle of 1994. Treasury yields lost their support as concerns about the US deficit raised questions over the willingness of foreign investors to continue to purchase Treasury securities, at least at the previous historically low yields. Municipal valuations also suffered a quick and severe setback as it became evident that the Build America Bond (“BAB”) program would expire at year-end. The program had opened the taxable market to municipal issuers, which had successfully alleviated supply pressure in the traditional tax-exempt marketplace, bringing down yields in that space.

The financial media has been replete with interviews, articles and presentations advertising the stress experienced in municipal finance, resulting in a loss of confidence among retail investors who buy individual bonds or mutual funds. From the middle of November through year-end, funds specializing in tax-exempt bonds witnessed weekly outflows averaging over $2.5 billion. Long-term and high-yield funds saw the greatest redemptions, followed by state-specific funds to a lesser but still significant degree. Demand usually is strong at the beginning of the new year against a backdrop of low new-issue supply, but the mutual fund outflows continued in January, putting additional upward pressure on municipal yields. Political uncertainty surrounding the midterm elections and the approach taken by the new Congress on issues such as income tax rates and alternative minimum tax (and the previously mentioned BAB non-extension) exacerbated the situation. All these conditions, combined with the seasonal illiquidity surrounding year-end holidays and dealers closing their fiscal books, sapped willing market participation from the trading community.

As demand for municipal securities from traditional retail investors was declining and trading desk liquidity was being curtailed, there was no comparable reduction in supply. As it became evident that the BAB program would be retired, issuers rushed deals to market both in the taxable municipal space and, to a lesser degree, in the traditional tax-exempt space. This imbalance in the supply/demand technicals provided the classic market action, leading to wider quality spreads and higher bond yields. The municipal curve steepened as the issuance was concentrated in longer (greater than 20-year) maturities. Curve steepening that began in October accelerated in November, spurred on by Treasury weakness, heavy supply and record outflows. As measured by Thomson Municipal Market Data, AAA-rated municipals rose nearly 82 basis points (“bps”) for maturities 25 years and longer from July 31, 2010, to January 31, 2011. The spread between two-year and 30-year maturities widened from 360 bps to 406 bps over the period.

The fundamental picture for municipalities will be subject to scrutiny for months to come, as the challenges to state and local budgets are real and need to be addressed with significant cuts to expenses and tax revenue increases. The debates around austerity measures needed to succeed in balancing these budgets are not over whether action needs to be taken, but over degree, approach and political will to accomplish these needs. The attention shone upon municipal finance has the potential to improve this market for the future if these efforts result in greater means toward disclosure and accuracy (and timeliness) of reporting. Early tests to judge progress will come soon as California, Illinois and Puerto Rico need to take austerity measures and access financing in the municipal market to address relatively immediate fiscal imbalances. BlackRock favors a more constructive outlook for the municipal market heading into 2011 as the typical, and this year particularly atypical, weakness passes.

Trust Summary as of January 31, 2011	BlackRock California Municipal Income Trust
Trust Overview

BlackRock California Municipal Income Trust’s (BFZ) (the “Trust”) investment objective is to provide current income exempt from regular US federal income and California income taxes. The Trust seeks to achieve its investment objective by investing primarily in municipal obligations exempt from federal income taxes (except that the interest may be subject to the federal alternative minimum tax) and California income taxes. The Trust invests, under normal market conditions, at least 80% of its assets in municipal obligations that are investment grade quality. The Trust may invest directly in such securities or synthetically through the use of derivatives.
	No assurance can be given that the Trust’s investment objective will be achieved.
Performance
For the six months ended January 31, 2011, the Trust returned (9.48)% based on market price and (8.55)% based on net asset value (“NAV”). For the same period, the closed-end Lipper California Municipal Debt Funds category posted an average return of (9.24)% based on market price and (8.09)% based on NAV. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The following discussion relates to performance based on NAV. A generally negative municipal market environment hindered Trust performance. Some widening of credit spreads, especially among California school districts and health care credits, detracted from Trust performance, as did a relatively long duration posture given the rising interest rate environment of the period. Conversely, the Trust maintained a low average cash reserve level, which benefited total return by delivering a competitive level of income accrual relative to the Lipper peer group. Increased exposure to tender option bonds to take advantage of the historically steep municipal yield curve also benefited the income accrual. In addition, the Trust’s holdings in corporate-backed municipals aided performance as non-traditional investors identified the sector’s attractive investment opportunities and subsequently drove up demand.

Trust Summary as of January 31, 2011 BlackRock Florida Municipal 2020 Term Trust

Trust Overview
BlackRock Florida Municipal 2020 Term Trust’s (BFO) (the “Trust”) investment objectives are to provide current income exempt from regular federal income tax and Florida intangible personal property tax and to return $15.00 per Common Share (the initial offering price per share) to holders of Common Shares on or about December 31, 2020. The Trust seeks to achieve its investment objectives by investing at least 80% of its assets in municipal bonds exempt from federal income taxes (except that the interest may be subject to the federal alternative minimum tax) and Florida intangible personal property tax. The Trust invests at least 80% of its assets in municipal bonds that are investment grade quality at the time of investment. The Trust actively manages the maturity of its bonds to seek to have a dollar weighted average effective maturity approximately equal to the Trust’s maturity date. The Trust may invest directly in such securities or synthetically through the use of derivatives. Effective January 1, 2007, the Florida intangible personal property tax was repealed.
	No assurance can be given that the Trust’s investment objective will be achieved.
Performance
For the six months ended January 31, 2011, the Trust returned (2.13)% based on market price and (3.53)% based on NAV. For the same period, the closed-end Lipper Other States Municipal Debt Funds category posted an average return of (8.40)% based on market price and (5.41)% based on NAV. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which narrowed 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. The Trust’s performance was aided by exposure to pre-refunded bonds and escrow bonds due to their shorter maturities, which was a benefit in the rising interest rate environment of the period. Conversely, the Trust’s holdings in the health care sector hindered performance as health care underperformed the general municipal market.

Trust Summary as of January 31, 2011 BlackRock Investment Quality Municipal Income Trust

Trust Overview

BlackRock Investment Quality Municipal Income Trust’s (RFA) (the “Trust”) investment objective is to provide high current income exempt from regular federal income tax and to provide an exemption from Florida intangible personal property taxes consistent with preservation of capital. The Trust seeks to achieve its investment objective by investing at least 80% of its assets in municipal obligations exempt from federal income taxes (except that the interest may be subject to the federal alternative minimum tax) and Florida intangible personal property tax. Under normal market conditions, the Trust invests at least 80% of its assets in municipal bonds rated investment grade at the time of investment. The Trust may invest directly in such securities or synthetically through the use of derivatives. Due to the repeal of the Florida intangible personal property tax, the Board approved an amended policy in September 2008 allowing the Trust the flexibility to invest in municipal obligations regardless of geographical location.

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

Performance

For the six months ended January 31, 2011, the Trust returned (9.83)% based on market price and (8.23)% based on NAV. For the same period, the closed-end Lipper General Municipal Debt Funds (Leveraged) category posted an average return of (8.46)% based on market price and (6.45)% based on NAV. All returns reflect reinvestment of dividends. The Trust’s premium to NAV, which narrowed 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. The Trust’s exposure to longer-duration and longer-maturity bonds detracted from performance as the long end of the yield curve steepened during the period. Additionally, the Trust’s holdings in the health care and transportation sectors hindered performance as both sectors underperformed the general municipal market. Conversely, the Trust’s holdings in corporate-backed municipals aided performance as non-traditional investors identified the sector’s attractive investment opportunities and subsequently drove up demand. In addition, the Trust benefited from exposure to the housing sector, which was one of the market’s better performers. Finally, the Trust’s exposure to shorter-duration bonds and premium coupon bonds (6% or higher) benefited performance in the rising interest rate environment of the period.

Trust Summary as of January 31, 2011 BlackRock New Jersey Municipal Income Trust

Trust Overview

BlackRock New Jersey Municipal Income Trust’s (BNJ) (the “Trust”) investment objective is to provide current income exempt from regular federal income tax and New Jersey gross income tax. The Trust seeks to achieve its investment objective by investing primarily in municipal bonds exempt from federal income taxes (except that the interest may be subject to the federal alternative minimum tax) and New Jersey gross income taxes. The Trust invests at least 80% of its assets in municipal bonds that are investment grade quality at the time of investment. The Trust may invest directly in such securities or synthetically through the use of derivatives.

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

Performance

For the six months ended January 31, 2011, the Trust returned (7.77)% based on market price and (5.67)% based on NAV. For the same period, the closed-end Lipper New Jersey Municipal Debt Funds category posted an average return of (9.78)% based on market price and (6.43)% based on NAV. All returns reflect reinvestment of dividends. The Trust’s premium to NAV, which narrowed 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. The Trust’s exposure to longer-duration and longer-maturity bonds detracted from performance as the long end of the yield curve steepened during the period. Conversely, the Trust’s holdings in corporate-backed municipals aided performance as non-traditional investors identified the sector’s attractive investment opportunities and subsequently drove up demand. In addition, the Trust benefited from exposure to the housing sector, which was one of the market’s better performers. Finally, the Trust’s exposure to shorter-duration bonds and premium coupon bonds (6% or higher) benefited performance in the rising interest rate environment of the period.

Trust Summary as of January 31, 2011 BlackRock New York Investment Quality Municipal Trust Inc.

Trust Overview

BlackRock New York Investment Quality Municipal Trust Inc.’s (RNY) (the “Trust”) investment objective is to provide high current income exempt from regular federal, New York State and New York City income tax consistent with the preservation of capital. The Trust seeks to achieve its investment objective by investing at least 80% of its assets in municipal obligations exempt from federal income taxes (except that the interest may be subject to the federal alternative minimum tax) and New York State and New York City income taxes. Under normal market conditions, the Trust invests at least 80% of its assets in securities rated investment grade at the time of investment. The Trust may invest directly in such securities or synthetically through the use of derivatives.

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

Performance

For the six months ended January 31, 2011, the Trust returned (9.46)% based on market price and (6.23)% based on NAV. For the same period, the closed-end Lipper New York Municipal Debt Funds category posted an average return of (6.95)% based on market price and (5.68)% based on NAV. All returns reflect reinvestment of dividends. The Trust’s premium to NAV, which narrowed 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. The Trust’s long duration bias was a significant detractor from performance in the rising interest rate environment of the period. A generally negative municipal market also hindered Trust performance, as did the Trust’s lack of exposure to the pre-refunded sector that led the municipal market. Similarly, the Trust’s exposure to the transportation sector detracted, as it was one of the poorest performers. Finally, the Trust’s large weighting in bonds with maturities greater than 25 years hurt performance as the long end of the municipal yield curve steepened. On the positive side, the Trust delivered an above-average yield relative to its Lipper category. In addition, the Trust’s holdings in corporate-backed municipals aided performance as non-traditional investors identified the sector’s attractive investment opportunities and subsequently drove up demand.

12 SEMI-ANNUAL REPORT JANUARY 31, 2011

The Benefits and Risks of Leveraging

The Trusts may utilize leverage to seek to enhance the yield and NAV of their common shares of beneficial interest (“Common Shares”). However, these objectives cannot be achieved in all interest rate environments.

To leverage, all the Trusts issue preferred shares (“Preferred Shares”), which pay dividends at prevailing short-term interest rates, and invest the proceeds in long-term municipal bonds. In general, the concept of leveraging is based on the premise that the financing 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 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 holders of Common Shares (“Common Shareholders”) will benefit from the incremental net income.

To illustrate these concepts, assume a Trust’s Common Shares capitalization is $100 million and it issues Preferred Shares for an additional $50 million, creating a total value of $150 million available for investment in long-term municipal bonds. 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 Trust pays dividends on the $50 million of Preferred Shares based on the lower short-term interest rates. At the same time, the securities purchased by the Trust with assets received from the Preferred Shares issuance earn income based on long-term interest rates. In this case, the dividends paid to holders of Preferred Shares (“Preferred Shareholders”) are significantly lower than the income earned on the Trust’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 Trust pays dividends on the higher short-term interest rate whereas the Trust’s total portfolio earns income based on lower long-term interest rates.

Furthermore, the value of the Trusts’ 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 Trusts’ Preferred Shares does not fluctuate in relation to interest rates. As a result, changes in interest rates can influence the Trusts’ NAV positively or negatively in addition to the impact on Trust performance from leverage from Preferred Shares discussed above.

The Trusts may also leverage their assets through the use of TOBs, as described in Note 1 of the Notes to Financial Statements. TOB investments generally will provide the Trusts with economic benefits in periods of declining short-term interest rates, but expose the Trusts to risks during periods of rising short-term interest rates similar to those associated with Preferred Shares issued by the Trusts, as described above. Additionally, fluctuations in the market value of municipal bonds deposited into the TOB may adversely affect each Trust’s NAV per share.

The use of leverage may enhance opportunities for increased income to the Trusts and Common Shareholders, but as described above, it also creates risks as short or long-term interest rates fluctuate. Leverage also will generally cause greater changes in the Trusts’ 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, the Trusts’ net income will be greater than if leverage had not been used. Conversely, if the income from the securities purchased is not sufficient to cover the cost of leverage, the Trusts’ 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 Trust may be required to sell portfolio securities at inopportune times or at distressed values in order to comply with regulatory requirements applicable to the use of leverage or as required by the terms of leverage instruments, which may cause a Trust to incur losses. The use of leverage may limit each Trust’s ability to invest in certain types of securities or use certain types of hedging strategies, such as in the case of certain restrictions imposed by ratings agencies that rate Preferred Shares issued by the Trusts. Each Trust 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, the Trusts are permitted to issue Preferred Shares in an amount of up to 50% of their total managed assets at the time of issuance. Under normal circumstances, each Trust anticipates that the total economic leverage from Preferred Shares and/or TOBs will not exceed 50% of its total managed assets at the time such leverage is incurred. As of January 31, 2011, the Trusts had economic leverage from Preferred Shares and/or TOBs as a percentage of their total managed assets as follows:

	Percent of Leverage
BFZ	44	%
BFO	38	%
RFA	43	%
BBF	44	%
RNJ	38	%
BNJ	38	%
RNY	38	%
BNY	39	%

Derivative Financial Instruments

The Trusts may invest in various derivative instruments, including financial futures 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 custody of securities or to hedge market and/or interest rate risks. Such derivative instruments involve risks, including the imperfect correlation between the value of a derivative instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the derivative instrument. The Trusts’ ability to successfully use a derivative instrument depends on the investment advisor’s ability to accurately predict pertinent market movements, which cannot be assured. The use of derivative instruments may result in losses greater than if they had not been used, may require a Trust to sell or purchase portfolio investments at inopportune times or for distressed values, may limit the amount of appreciation a Trust can realize on an investment, may result in lower dividends paid to shareholders or may cause a Trust to hold an investment that it might otherwise sell. The Trusts’ investments in these instruments are discussed in detail in the Notes to Financial Statements.

	•	Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Trust’s own assumptions used in determining the fair value of investments)
	The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Trust’s policy regarding valuation of investments and other significant accounting policies, please refer to Note 1 of the Notes to Financial Statements.

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

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

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

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

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

• For Trust compliance purposes, the Trust’s sector classifications refer to any one or more of the sector sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Trust management. This definition may not apply for purposes of this report, which may combine such sector sub-classifications for reporting ease.

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

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

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

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

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

The following table summarizes the inputs used as of January 31, 2011 in determining the fair valuation of the Trust’s investments:

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

Notes to Financial Statements (Unaudited)

1. Organization and Significant Accounting Policies:

BlackRock New Jersey Investment Quality Municipal Trust Inc. (“RNJ”) and BlackRock New York Investment Quality Municipal Trust Inc. (“RNY”) are organized as Maryland corporations. BlackRock Investment Quality Municipal Income Trust (“RFA”) is organized as a Massachusetts business trust. RNJ, RNY and RFA are herein referred to as the “Investment Quality Trusts.” BlackRock California Municipal Income Trust (“BFZ”), BlackRock Municipal Income Investment Trust (“BBF”), BlackRock New Jersey Municipal Income Trust (“BNJ”), BlackRock New York Municipal Income Trust (“BNY”) (collectively, the “Income Trusts”) and BlackRock Florida Municipal 2020 Term Trust (“BFO”) are organized as Delaware statutory trusts. The Investment Quality Trusts, Income Trusts and BFO are referred to herein collectively as the “Trusts.” The Trusts are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as non-diversified, closed-end management investment companies. The Trusts’ 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 disclosures in the financial statements. Actual results could differ from those estimates. The Trusts determine, and make available for publication the net asset value of their Common Shares on a daily basis.

Reorganization: The Board and shareholders of BFZ and the Board and shareholders of each of BlackRock California Insured Municipal Income Trust (“BCK”), BlackRock California Municipal Bond Trust (“BZA”) and BlackRock California Municipal Income Trust II (“BCL”) (individually, a “Target Fund” and collectively the “Target Funds”) approved the reorganizations of BCK, BZA and BCL into BFZ, pursuant to which BFZ acquired substantially all of the assets and substantially all of the liabilities of BCK, BZA and BCL in exchange for an equal aggregate value of newly-issued Common Shares and Preferred Shares of BFZ.

Each Common Shareholder of a Target Fund received Common Shares of BFZ in an amount equal to the aggregate net asset value of such Common Shareholder’s Target Fund Common Shares, as determined at the close of business on January 29, 2010, less the costs of the Target Fund’s reorganization (although cash was distributed for any fractional Common Shares).

Each Preferred Shareholder of a Target Fund received Preferred Shares of BFZ in an amount equal to the aggregate liquidation preference of the Target Fund Preferred Shares held by such Preferred Shareholder prior to the Target Fund’s reorganization.

The reorganizations were accomplished by a tax-free exchange of Common Shares and Preferred Shares of BFZ in the following amounts and at the following conversion ratios:

Common Shares
	Shares Prior to Reorganization		Conversion Ratio		Shares of BFZ
BCK		5,278,087		0.97545266		5,148,524
BZA		3,409,668		1.04504339		3,563,251
BCL		7,999,789		0.99301332		7,943,897

	Series F-7		Series R-7		Series T-7
BCK		1,253		—		—
BZA		898		—		—
BCL		—		931		931

Each Target Fund’s net assets and composition of net assets on January 29, 2010, the date of the merger, were as follows:

	Net Assets Applicable to Common Shareholders		Preferred Shares at Liquidation Preference		Paid in Capital
BCK	$	70,787,151	$	31,325,000	$	4,722,726
BZA	$	48,990,979	$	22,450,000	$	48,275,547
BCL	$	109,220,636	$	46,550,000	$	113,337,925

	Undistributed Net Investment Income		Accumulated Net Realized Loss			Net Unrealized Appreciation/ Depreciation
BCK	$	13,660	$	(2,517,189	)	$	(1,432,046	)
BZA	$	8,847	$	(560,343	)	$	1,266,928
BCL	$	67,073	$	(7,251,617	)	$	3,067,255

For financial reporting purposes, assets received and shares issued by BFZ were recorded at fair value; however, the cost basis of the investments received from the Target Funds were carried forward to align ongoing reporting of BFZ’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

The aggregate net assets of BFZ immediately after the acquisition amounted to $437,406,830. Each Target Fund’s fair value and cost of investments prior to the reorganization were as follows:

	Fair Value of Investments		Cost of Investments
BCK	$	108,191,823	$	109,623,869
BZA	$	76,672,439	$	75,405,511
BCL	$	175,462,460	$	172,395,205

SEMI-ANNUAL REPORT JANUARY 31, 2011 57

Notes to Financial Statements (continued)

The purpose of these transactions was to combine four funds managed by the Manager with the same or substantially similar (but not identical) investment objectives, investment policies, strategies, risks and restrictions. Each reorganization was a tax-free event and was effective on February 1, 2010.

In connection with the reorganizations, BFZ’s investment advisory fee was reduced by 2 basis points, from 0.60% of BFZ’s average weekly net assets to 0.58% of BFZ’s average weekly net assets as defined in Note 3. In addition to this reduction, BFZ’s contractual investment advisory fee waiver, as a percentage of average weekly net assets, was extended for an additional two years as follows: (i) 0.05% through December 31, 2010, (ii) 0.03% through December 31, 2011 and (iii) 0.01% through December 31, 2012.

Assuming the acquisition had been completed on August 1, 2009, the beginning of the annual reporting period of BFZ, the pro forma results of operations for the year ended July 31, 2010, are as follows:

• Net investment income: $30,885,392

• Net realized and change in unrealized gain on investments: $41,142,437

• Dividends to Preferred Shareholders from net investment income: $(711,091)

• Net increase in net assets applicable to Common Shareholders resulting from operations: $71,316,738

Because the combined investment portfolios have been managed as a single integrated portfolio since the acquisition was completed, it is not practicable to separate the amounts of revenue and earnings of BFZ that have been included in BFZ’s Statement of Operations since January 29, 2010.

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

Valuation: The Trusts fair value their financial instruments at market value using independent dealers or pricing services under policies approved by the Boards of Directors and the Boards of Trustees of the Trusts (referred to throughout this report as the “Board of Trustees” or the “Board”). Municipal investments (including commitments to purchase such investments on a “when-issued” basis) are valued on the basis of prices provided by dealers or pricing services. 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 and information with respect to various relationships between investments. Financial futures contracts traded on exchanges are valued at their last sale price. Short-term securities with remaining maturities of 60 days or less may be valued at amortized cost, which approximates fair value. Investments in open-end registered investment companies are valued at net asset value each business day.

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 Trust might reasonably expect to receive from the current sale of that asset in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the investment advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof.

Forward Commitments and When-Issued Delayed Delivery Securities: The Trusts may purchase securities on a when-issued basis and may purchase or sell securities on a forward commitment basis. Settlement of such transactions normally occurs within a month or more after the purchase or sale commitment is made. The Trusts may purchase securities under such conditions with the intention of actually acquiring them, but may enter into a separate agreement to sell the securities before the settlement date. Since the value of securities purchased may fluctuate prior to settlement, the Trusts may be required to pay more at settlement than the security is worth. In addition, the Trusts are not entitled to any of the interest earned prior to settlement. When purchasing a security on a delayed delivery basis, the Trusts assume the rights and risks of ownership of the security, including the risk of price and yield fluctuations. In the event of default by the counter-party, the Trusts’ maximum amount of loss is the unrealized appreciation of unsettled when-issued transactions, which is shown on the Schedules of Investments, if any.

Zero-Coupon Bonds: The Trusts may invest in zero-coupon bonds, which are normally issued at a significant discount from face value and do not provide for periodic interest payments. Zero-coupon bonds may experience greater volatility in market value than similar maturity debt obligations which provide for regular interest payments.

Municipal Bonds Transferred to Tender Option Bond Trusts: The Trusts leverage their assets through the use of TOBs. A TOB is established by a third party sponsor forming a special purpose entity, into which one or more funds, or an agent on behalf of the funds, transfers municipal bonds. Other funds managed by the investment advisor may also contribute municipal bonds to a TOB into which a Trust has contributed bonds. A TOB typically issues two classes of beneficial interests: short-term floating rate certificates, which are sold to third party investors, and residual certificates (“TOB Residuals”), which are generally issued to the participating funds that made the transfer. The TOB Residuals held by a Trust include the right of a Trust (1) to cause the holders of a proportional share of the short-term floating rate certificates to tender their certificates at par, including during instances of a rise in short-term interest rates, and (2) to transfer, within seven days, a corresponding share of the municipal bonds from the TOB to a Trust. The TOB may also be terminated without the consent of a Trust upon the occurrence of certain events as defined in the TOB agreements. Such termination events may include the bankruptcy or default of the municipal bond, a substantial downgrade in credit quality of the municipal bond, the inability of the TOB to obtain quarterly or annual renewal of the liquidity support agreement, a substantial decline in market value of the municipal bond or the inability to remarket the short-term floating rate certificates to third party investors. During the six months ended January 31, 2011, no TOBs that the Trusts participated in were terminated without the consent of the Trusts.

58 SEMI-ANNUAL REPORT JANUARY 31, 2011

Notes to Financial Statements (continued)

The cash received by the TOB from the sale of the short-term floating rate certificates, less transaction expenses, is paid to a Trust, which typically invests the cash in additional municipal bonds. Each Trust’s transfer of the municipal bonds to a TOB is accounted for as a secured borrowing, therefore the municipal bonds deposited into a TOB are presented in the Trusts’ Schedules of Investments and the proceeds from the issuance of the short-term floating rate certificates are shown as trust certificates in the Statements of Assets and Liabilities.

Interest income, including amortization and accretion of premiums and discounts, from the underlying municipal bonds is recorded by the Trusts on an accrual basis. Interest expense incurred on the secured borrowing and other expenses related to remarketing, administration and trustee services to a TOB are shown as interest expense and fees in the Statements of Operations. The short-term floating rate certificates have interest rates that generally reset weekly and their holders have the option to tender certificates to the TOB for redemption at par at each reset date. At January 31, 2011, the aggregate value of the underlying municipal bonds transferred to TOBs, the related liability for trust certificates and the range of interest rates on the liability for trust certificates were as follows:

	Underlying Municipal Bonds Transferred to TOBs		Liability for Trust Certificates		Range of Interest Rates
BFZ	$	264,827,303	$	144,495,478		0.27 % – 0.38%
BFO	$	7,865,305	$	4,136,402		0.34 % – 0.44%
RFA	$	8,071,816	$	4,556,817		0.29 % – 0.44%
BBF	$	54,446,445	$	30,617,038		0.29 % – 0.36%
RNJ	$	228,719	$	159,917		0.35%
BNJ	$	3,892,090	$	2,359,296		0.33 % – 0.35%
RNY	$	1,079,990	$	569,974		0.29 % – 0.56%
BNY	$	20,968,414	$	11,089,474		0.22 % – 0.56%

For the six months ended January 31, 2011, the Trusts’ average trust certificates outstanding and the daily weighted average interest rates, including fees, were as follows:

	Average Trust Certificates Outstanding		Daily Weighted Average Interest Rate
BFZ	$	155,867,704		0.82%
BFO	$	4,214,080		0.73%
RFA	$	4,535,158		0.81%
BBF	$	30,354,261		0.84%
RNJ	$	159,917		0.86%
BNJ	$	2,359,296		0.84%
RNY	$	569,974		0.83%
BNY	$	11,855,125		0.77%

Should short-term interest rates rise, the Trusts’ investments in TOBs may adversely affect the Trusts’ net investment income and dividends to Common Shareholders. Also, fluctuations in the market values of municipal bonds deposited into the TOB may adversely affect the Trusts’ net asset values per share.

Segregation and Collateralization: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission (“SEC”) require that the Trusts either deliver collateral or segregate assets in connection with certain investments (e.g., financial futures contracts), the Trusts 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 transactions are entered into (the trade dates). Realized gains and losses on investment transactions are determined on the identified cost basis. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized on the accrual basis. Dividend income is recorded on the ex-dividend dates.

Dividends and Distributions: Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. The amount and timing of dividends and distributions are determined in accordance with federal income tax regulations, which may differ from US GAAP. Dividends and distributions to Preferred Shareholders are accrued and determined as described in Note 7.

Income Taxes: It is each Trust’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.

Each Trust files US federal and various state and local tax returns. No income tax returns are currently under examination. The statutes of limitations on Investment Quality Trusts’ and Income Trusts’ US federal tax returns remains open for each of the two years ended July 31, 2010 and 2009, and the period ended July 31, 2008 and the year ended October 31, 2007. The statutes of limitations on BFO’s US federal tax returns remain open for the two years ended July 31, 2010 and 2009, the period ended July 31, 2008 and the year ended December 31, 2007. The statutes of limitations on the Trusts’ state and local tax returns may remain open for an additional year depending upon the jurisdiction. Management does not believe there are any 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 Trust’s Board, non-interested Trustees (“Independent Trustees”) may defer a portion of their annual complex-wide compensation. Deferred amounts earn an approximate return as though equivalent dollar amounts had been invested in common shares of certain other BlackRock Closed-End Funds selected by the Independent Trustees. This has approximately the same economic effect for the Independent Trustees as if the Independent Trustees had invested the deferred amounts directly in certain other BlackRock Closed-End Funds.

SEMI-ANNUAL REPORT JANUARY 31, 2011 59

Notes to Financial Statements (continued)

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

Other: Expenses directly related to a Trust are charged to that Trust. Other operating expenses shared by several funds are pro rated among those funds on the basis of relative net assets or other appropriate methods.The Trusts have an arrangement with the custodian whereby fees may be reduced by credits earned on uninvested cash balances, which if applicable are shown as fees paid indirectly in the Statements of Operations.The custodian 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 Trusts engage in various portfolio investment strategies using derivative contracts both to increase the returns of the Trusts and to economically hedge, or protect, their exposure to certain risks such as interest rate risk. These contracts may be transacted on an exchange.

Losses may arise if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument or if the counterparty does not perform under the contract. Counterparty risk related to exchange-traded financial futures contracts is deemed to be minimal due to the protection against defaults provided by the exchange on which these contracts trade.

Financial Futures Contracts: The Trusts 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). Financial futures contracts are agreements between the Trust and counter-party 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 or by payment of a cash settlement amount on settlement date. Pursuant to the contract, the Trusts agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as margin variation and are recorded by the Trusts as unrealized gains or losses. When the contract is closed, the Trusts record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The use of financial futures transactions involves the risk of an imperfect correlation in the movements in the price of financial futures contracts, interest rates and the underlying assets.

3. Investment Advisory Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. (“PNC”), Bank of America Corporation (“BAC”) and Barclays Bank PLC (“Barclays”) are the largest stockholders of BlackRock, Inc. (“BlackRock”). Due to the ownership structure, PNC is an affiliate of the Trusts for 1940 Act purposes, but BAC and Barclays are not.

Each Trust entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Manager”), the Trusts’ investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services. The Manager is responsible for the management of each Trust’s portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of each Trust. For such services, each Trust pays the Manager a monthly fee at the following annual rates of each Trust’s average weekly net assets as follows:

BFZ	0.58	%
BFO	0.50	%
RFA	0.35	%
BBF	0.60	%
RNJ	0.35	%
BNJ	0.60	%
RNY	0.35	%
BNY	0.60	%

Average weekly net assets is the average weekly value of each Trust’s total assets minus the sum of its accrued liabilities.

The Manager contractually agreed to waive a portion of the investment advisory fee on BFZ at an annual rate of 0.05% of average daily net assets through December 31, 2010, 0.03% through December 31, 2011 and 0.01% through December 31, 2012. For the six months ended January 31, 2011, the Manager waived $191,323, which is included in fees waived by advisor in the Statements of Operations.

60 SEMI-ANNUAL REPORT JANUARY 31, 2011

Notes to Financial Statements (continued)

The Manager voluntarily agreed to waive its investment advisory fees by the amount of investment advisory fees each Trust pays to the Manager indirectly through its investment in affiliated money market funds, however the Manager does not waive its investment advisory fees by the amount of investment advisory fees paid through each Trust’s investment in other affiliated investment companies, if any. These amounts are shown as, or included in, fees waived by advisor in the Statements of Operations. For the six months ended January 31, 2011, the amounts waived were as follows:

BFZ	$	2,983
BFO	$	3,287
RFA	$	47
BBF	$	441
RNJ	$	1,211
BNJ	$	7,059
RNY	$	482
BNY	$	4,046

Each Investment Quality Trust has an Administration Agreement with the Manager. The administration fee paid to the Manager is computed weekly and payable monthly based on an annual rate of 0.10% of each respective Trust’s average weekly net assets for the Investment Quality Trusts.

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 percentage of the investment advisory fees paid by each Trust to the Manager.

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

BFZ	$	6,275
BFO	$	434
BBF	$	669
BNJ	$	643
BNY	$	1,159

Effective January 1, 2011, the Trusts no longer reimburse the Manager for accounting services.

Certain officers and/or trustees of the Trusts are officers and/or directors of BlackRock or its affiliates. The Trusts reimburse the Manager for compensation paid to the Trusts’ Chief Compliance Officer.

SEMI-ANNUAL REPORT JANUARY 31, 2011 61

Notes to Financial Statements (continued)

6. Concentration, Market and Credit Risk:

Each Trust invests a substantial amount of its assets in issuers located in a single state or limited number of states. Please see the Schedules of Investments for concentrations in specific states.

Many municipalities insure repayment of their bonds, which may reduce the potential for loss due to credit risk. The market value of these bonds may fluctuate for other reasons, including market perception of the value of such insurance, and there is no guarantee that the insurer will meet its obligation.

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

As of January 31, 2011, BFZ invested a significant portion of its assets in securities in the County/City/Special District/School District and Utilities sectors. BFO and RNY invested a significant portion of their assets in securities in the County/City/Special District/School District sector. RFA invested a significant portion of its assets in securities in the Utilities sector. BBF invested a significant portion of its assets in securities in the Health, County/City/Special District/School District and Utilities sectors. RNJ and BNJ invested a significant portion of their assets in securities in the State sector. Changes in economic conditions affecting the Utilities, County/City/Special District/School District, Health and State sectors would have a greater impact on the Trusts and could affect the value, income and/or liquidity of positions in such securities.

7. Capital Share Transactions:

Each Investment Quality Trust is authorized to issue 200 million shares, including Preferred Shares, par value $0.01 per share, all of which were initially classified as Common Shares.There are an unlimited number of $0.001 par value Common Shares authorized for the Income Trusts and BFO. Each Trust’s Board is authorized, however, to reclassify any unissued shares without approval of Common Shareholders.At January 31, 2010, Common Shares of BFO owned by affiliates of the Manager was 8,028 shares.

Common Shares

For the six months ended January 31, 2011 and the year ended July 31, 2010, shares issued and outstanding increased by the following amounts as a result of dividend reinvestment:

	Six Months Ended January 31, 2011		Year Ended July 31, 2010
BFZ		13,214		10,114
RFA		259		551
BBF		3,966		3,240
RNJ		1,019		2,699
BNJ		10,834		28,026
RNY		1,548		1,225
BNY		24,133		50,502

Shares issued and outstanding remained constant for BFO for the six months ended January 31, 2011 and the year ended July 31, 2010.

Preferred Shares

The Preferred Shares are redeemable at the option of each Trust, in whole or in part, on any dividend payment date at their liquidation preference per share plus any accumulated and unpaid dividends whether or not declared. The Preferred Shares are 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 Trust, as set forth in each Trust’s Articles of Amendment/Statement of Preferences (the “Governing Instrument”) are not satisfied.

From time to time in the future, each Trust may effect repurchases of its Preferred Shares at prices below their liquidation preference as agreed upon by the Trust and seller. Each Trust also may redeem its Preferred Shares from time to time as provided in the applicable Governing Instrument. Each Trust intends to effect such redemptions and/or repurchases to the extent necessary to maintain applicable asset coverage requirements or for such other reasons as the Board may determine.

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, the holders of Preferred Shares, voting as a separate class, are also entitled to elect two Trustees for each Trust. In addition, the 1940 Act requires that along with approval by shareholders that might otherwise be required, the approval of

62 SEMI-ANNUAL REPORT JANUARY 31, 2011

Notes to Financial Statements (concluded)

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 Trust’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.

The Trusts had the following series of Preferred Shares outstanding, effective yields and reset frequency as of January 31, 2011:

	Series		Preferred Shares		Effective Yield			Reset Frequency Days
BFZ		F7		2,151		0.44	%		7
		R7		2,351		0.44	%		7
		T7		2,351		0.44	%		7
BFO		F7		1,716		0.44	%		7
RFA		R7		183		0.44	%		7
BBF		T7		1,370		0.44	%		7
RNJ		T7		276		0.44	%		7
BNJ		R7		2,364		0.44	%		7
RNY		F7		389		0.44	%		7
BNY		F7		1,890		0.44	%		7
		W7		1,890		0.44	%		7

Dividends on seven-day Preferred Shares are cumulative at a rate, which 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, each Trust is 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 all series of Preferred Shares is the higher of 110% of the AA commercial paper rate or 100% of 90% of the Kenny S&P 30-day High Grade Index rate divided by 1.00 minus the marginal tax rate. The low, high and average dividend rates on the Preferred Shares for each Trust for the six months ended January 31, 2011 were as follows:

	Series		Low			High			Average
BFZ		F7		0.37	%		0.50	%		0.42	%
		R7		0.37	%		0.50	%		0.42	%
		T7		0.37	%		0.50	%		0.42	%
BFO		F7		0.37	%		0.50	%		0.42	%
RFA		R7		0.37	%		0.50	%		0.42	%
BBF		T7		0.37	%		0.50	%		0.42	%
RNJ		T7		0.37	%		0.50	%		0.42	%
BNJ		R7		0.37	%		0.50	%		0.42	%
RNY		F7		0.37	%		0.50	%		0.42	%
BNY		F7		0.37	%		0.50	%		0.42	%
		W7		0.37	%		0.50	%		0.42	%

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 0.37% to 0.50% for the six months ended January 31, 2011. A failed auction is not an event of default for the Trusts but it has a negative impact on the liquidity of Preferred Shares. A failed auction occurs when there are more sellers of a Trust’s auction rate Preferred Shares than buyers. A successful auction for the Trusts’ Preferred Shares may not occur for some time, if ever, and even if liquidity does resume, Preferred Shareholders may not have the ability to sell the Preferred Shares at their liquidation preference.

The Trusts 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 Trusts pay commissions of 0.15% on the aggregate principal amount of all shares that fail to clear their auctions and 0.25% on the aggregate principal amount of all shares that successfully clear their auctions. Certain broker dealers have individually agreed to reduce commissions for failed auctions.

Preferred Shares issued and outstanding remained constant for the six months ended January 31, 2011 and the year ended July 31, 2010 for all Trusts, except BFZ.

8. Subsequent Events:

Management’s evaluation of the impact of all subsequent events on the Trusts’ financial statements was completed through the date the financial statements were issued and the following items were noted:

The Trusts paid a net investment income dividend in the following amounts per share on March 1, 2011 to Common Shareholders of record on February 15, 2011:

Dividend Policy

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

General Information

On July 29, 2010, BlackRock Advisors, LLC, the Trusts’ investment advisor (the “Manager”), announced that a shareholder derivative complaint was filed on July 27, 2010 in the Supreme Court of the State of New York, New York County with respect to BFZ and BNJ, which had previously received a demand letter from a law firm on behalf of each trust’s common shareholders. The complaint was filed against the Manager, BlackRock, Inc., BFZ, BNJ and certain of the directors, officers and portfolio managers (collectively, the “BlackRock Parties”) in connection with the redemption of auction-market preferred shares, auction rate preferred securities, auction preferred shares and auction rate securities (collectively, “AMPS”). The complaint alleges, among other things, that the BlackRock Parties breached their fiduciary duties to the common shareholders of BFZ and BNJ (the “Shareholders”) by redeeming AMPS at their liquidation preference and alleges that such redemptions caused losses to the Shareholders. The plaintiffs are seeking monetary damages for the alleged losses suffered and to enjoin BFZ and BNJ from future redemptions of AMPS at their liquidation preference. The BlackRock Parties believe that the claims asserted in the complaint are without merit and intend to vigorously defend themselves in the litigation.

On March 29, 2011, the Manager announced that BBF received a demand letter from a law firm on behalf of BBF’s common shareholders. The demand letter alleges that the Manager and BBF’s officers and Board of Trustees (the “Board”) breached their fiduciary duties by redeeming at par certain of BBF’s Preferred Shares, and demanded that the Board take action to remedy those alleged breaches. The Independent Directors are reviewing the matter with independent counsel.

This report is transmitted to shareholders only. It is not a prospectus. Past performance results shown in this report should not be considered a representation of future performance. The Trusts have leveraged their Common Shares, which creates risks for Common Shareholders, including the likelihood of greater volatility of net asset value and market price of the Common Shares, and the risk that fluctuations in short-term dividend rates of the Preferred Shares, currently set at the maximum reset rate as a result of failed auctions, may reduce the Common Shares’ yield. Statements and other information herein are as dated and are subject to change.
