2 SEMI-ANNUAL REPORT JANUARY 31, 2010

Dear Shareholder

Over the past year, investors worldwide witnessed a seismic shift in market sentiment as guarded optimism replaced the fear and pessimism that had dominated since late 2007. The single most important reason for this change was the swing from a severe economic recession to an emergent global recovery.

At the start of 2009, markets were reeling from the virtually unprecedented global financial and economic meltdown. The looming threat of further collapse in global markets prompted stimulus packages and central bank interventions on an extraordinary scale. By period end, these actions had helped stabilize the financial system, and the economic contraction abated.

After reaching a trough in March 2009, stocks galloped higher as the massive, coordinated global monetary and fiscal stimulus began to re-inflate world economies. Sidelined cash poured into the markets, triggering a dramatic and steep upward rerating of stocks and other risk assets. Still, the rally has not been without interruption, as mixed economic data, global challenges regarding sovereign credit risk and proposed fees and levies on banks had begun to dampen investor conviction toward period end. The experience in international markets generally mirrored that seen in the United States; notably, emerging markets firmly reclaimed their leadership status.

The easing of investor risk aversion was notable in the fixed income markets as well, where non-Treasury assets made a robust recovery. One of the major themes over the past year was the reversal of the flight-to-quality trade. High yield finished the period as the strongest-performing fixed income sector in both the taxable and tax-exempt space. Overall, the municipal market made a strong showing as technical conditions remained supportive of the asset class. The Build America Bond program was deemed a success, adding $65 billion of taxable supply to the municipal marketplace in 2009 and $4 billion so far this year. The program continues to alleviate tax-exempt supply pressure and attract the attention of a global audience. However, fundamental concerns are moving to the fore in the municipal space, and bear close watching as the year progresses. At the same time, yields on money market securities declined throughout the reporting period and remain near all-time lows, with the Federal Open Market Committee reiterating that economic circumstances are likely to necessitate an accommodative interest rate stance for an “extended period.” Investor assets in money market funds declined from the peak registered in early 2009, but remain well above pre-crisis levels.

All told, the rebound in sentiment and global market conditions resulted in positive 6- and 12-month returns for nearly every major benchmark index, with the most dramatic improvement seen among risk assets.

Trust Summary as of January 31, 2010 BlackRock California Investment Quality Municipal Trust Inc.

Investment Objective

BlackRock California Investment Quality Municipal Trust Inc. (RAA) (the “Trust”) seeks to provide high current income which, in the opinion of bond counsel to the issuer, is exempt from regular federal and California income tax consistent with preservation of capital.

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

Performance

For the six months ended January 31, 2010, the Trust returned 8.80% based on market price and 9.89% based on net asset value (“NAV”). For the same period, the closed-end Lipper California Municipal Debt Funds category posted an average return of 9.46% based on market price and 11.46% on a NAV basis. 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. During the period, tightening of credit quality spreads benefited the lower-rated sector of the portfolio. Corporate-backed and health municipals were notable contributors. A fully-invested posture and a slightly longer relative duration posture also were additive, as rates declined in the second half of 2009. Throughout this period, the municipal market benefited from the Build America Bond Program, which effectively moved supply to the taxable market and, thus, alleviated supply pressure in the tax-exempt space. The Trust increased its net income balances by focusing on bolstering accrual, but still needs to improve its relative yield in order to provide a competitive dividend distribution. A below-average distribution yield detracted from total return results.

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

Trust Summary as of January 31, 2010 BlackRock California Municipal Income Trust

Investment Objective

BlackRock California Municipal Income Trust (BFZ) (the “Trust”) seeks to provide high current income which, in the opinion of bond counsel to the issuer, is exempt from regular federal income tax and California income taxes.

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

For the six months ended January 31, 2010, the Trust returned 9.53% based on market price and 11.90% based on NAV. For the same period, the closed-end Lipper California Municipal Debt Funds category posted an average return of 9.46% based on market price and 11.46% on a NAV basis. 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 Trust maintains a relatively generous degree of income accrual, which was a positive factor. In addition, tightening of credit quality spreads benefited the lower-rated sector of the portfolio. Corporate-backed and health municipals were notable contributors. A fully-invested posture and a slightly longer relative duration posture also were additive, as rates declined in the second half of 2009. Throughout this period, the municipal market benefited from the Build America Bond Program, which effectively moved supply to the taxable market and, thus, alleviated supply pressure in the tax-exempt space. Conversely, the Trust’s exposure to zero-coupon bonds hindered performance. These securities fell out of favor with the retail audience that characteristically supports this structure and, thus, did not participate in the general move to better municipal bond prices.

SEMI-ANNUAL REPORT JANUARY 31, 2010 5

Trust Summary as of January 31, 2010 BlackRock Florida Municipal 2020 Term Trust

Investment Objective

BlackRock Florida Municipal 2020 Term Trust (BFO) (the “Trust”) seeks to provide current income that is exempt from regular federal income tax and Florida intangible personal property taxes and to return $15.00 per share (the initial public offering price) on or about December 31, 2020.

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

Performance

For the six months ended January 31, 2010, the Trust returned 11.49%, based on market price and 9.10%, based on NAV. For the same period, the closed-end Lipper Florida Municipal Debt Funds category posted an average return of 11.77% based on market price and 8.96% on a NAV basis. 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 Trust’s allocations to the industrial development revenue/pollution control revenue and health sectors aided performance, as these represented two of the best-performing sectors for the period. The Trust is managed to a December 31, 2020 termination date, and as such, will have a shorter average duration than its peer group. This detracted from performance during a period of general interest rate decline.

Trust Summary as of January 31, 2010 BlackRock Investment Quality Municipal Income Trust

Investment Objective

BlackRock Investment Quality Municipal Income Trust (RFA) (the “Trust”) seeks to provide current income which, in the opinion of bond counsel to the issuer, is exempt from regular federal income tax and to provide an exemption from Florida intangible personal property taxes consistent with preservation of capital. The Trust may invest in municipal obligations regardless of geographic location.

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

Performance

For the six months ended January 31, 2010, the Trust returned 23.53% based on market price and 10.10% based on NAV. For the same period, the closed-end Lipper General Municipal Debt Funds (Leveraged) category posted an average return of 13.14% based on market price and 12.60% on a NAV basis. All returns reflect reinvestment of dividends. The Trust moved from a discount to NAV to a premium by period end, which accounts for the difference between performance based on price and performance based on NAV. The Trust held a higher concentration in health and housing bonds with maturities of 20 years and longer, which benefited performance as the municipal yield curve flattened during the last six months. Meanwhile, we continued to restructure the Trust’s holdings in line with its transition from a Florida fund to a national portfolio. The process is not yet complete, however, and the higher concentration of Florida holdings detracted from recent performance.

8 SEMI-ANNUAL REPORT JANUARY 31, 2010

Trust Summary as of January 31, 2010	BlackRock New Jersey Investment Quality Municipal Trust Inc.
Investment Objective

BlackRock New Jersey Investment Quality Municipal Trust Inc. (RNJ) (the “Trust”) seeks to provide high current income which, in the opinion of bond counsel to the issuer, is exempt from regular federal income tax and New Jersey gross income tax consistent with preservation of capital.

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

Performance

For the six months ended January 31, 2010, the Trust returned 27.23% based on market price and 10.95% based on NAV. For the same period, the closed-end Lipper New Jersey Municipal Debt Funds category posted an average return of 13.70% based on market price and 10.42% on a NAV basis. All returns reflect reinvestment of dividends. The Trust’s premium to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The Trust held overweight positions in health and housing bonds with maturities of 20 years and longer, which benefited performance as the municipal yield curve flattened during the last six months. Conversely, relative performance was negatively affected by the Trust’s slight overweight in zero-coupon bonds. The Trust’s cash balance rose to nearly 8% by period end (from approximately 2% at the end of the calendar year), due primarily to some profit-taking in an overweighted portfolio holding. The Trust’s overall cash position did not have a material impact on performance.

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

SEMI-ANNUAL REPORT JANUARY 31, 2010 9

Trust Summary as of January 31, 2010	BlackRock New Jersey Municipal Income Trust
Investment Objective

BlackRock New Jersey Municipal Income Trust (BNJ) (the “Trust”) seeks to provide high current income which, in the opinion of bond counsel to the issuer, is exempt from regular federal income tax and New Jersey gross income tax.

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

Performance

For the six months ended January 31, 2010, the Trust returned 4.91% based on market price and 12.66% based on NAV. For the same period, the closed-end Lipper New Jersey Municipal Debt Funds category posted an average return of 13.70% based on market price and 10.42% on a NAV basis. 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 Trust held overweight positions in health and housing bonds with maturities of 20 years and longer, which benefited performance as the municipal yield curve flattened during the last six months. Conversely, relative performance was negatively affected by the Trust’s slight over-weight in zero-coupon bonds.

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

10 SEMI-ANNUAL REPORT JANUARY 31, 2010

Trust Summary as of January 31, 2010	BlackRock New York Investment Quality Municipal Trust Inc.
Investment Objective

BlackRock New York Investment Quality Municipal Trust Inc. (RNY) (the “Trust”) seeks to provide high current income which, in the opinion of bond counsel to the issuer, is exempt from regular federal income taxes and New York State and New York City income tax consistent with preservation of capital.

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

Performance

For the six months ended January 31, 2010, the Trust returned 8.58% based on market price and 10.68% based on NAV. For the same period, the closed-end Lipper New York Municipal Debt Funds category posted an average return of 7.74% based on market price and 10.02% on a NAV basis. 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 Trust’s holdings of longer-dated and discount-coupon bonds aided relative performance; these issues outperformed as the market recovered and credit spreads tightened during the six months. Additionally, fund management was active in the new-issue market, which benefited the Trust by adding diversification and better-structured bonds to the portfolio. An above-average accrual rate was a positive factor as well. On the other hand, the Trust’s higher-coupon bonds with shorter call protection detracted from performance for the period, as their shorter duration and negative convexity caused them to lag. Exposure to zero-coupon bonds also hindered results. The Trust maintained low cash balances during the six months (averaging less than 1%), which was a positive contributor to both income and performance as the market rallied.

The Benefits and Risks of Leveraging

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

To leverage, the Trusts issue 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 cost of assets to be obtained from leverage will be based on short-term interest rates, which normally will be lower than the income earned by each Trust on its longer-term portfolio investments. To the extent that the total assets of each Trust (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, each Trust’s 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 the income based on long-term interest rates. In this case, the dividends paid to 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 Trust’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 Trust’s Preferred Shares does not fluctuate in relation to interest rates. As a result, changes in interest rates can influence the Trust’s 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 tender option bond (“TOB”) programs, 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 trust may adversely affect each Trust’s NAV per share.

The use of leverage may enhance opportunities for increased returns 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’ NAV, market price and dividend rate than a comparable portfolio 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 Trust. 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 its 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, 2010, the Trusts had economic leverage from Preferred Shares and/or TOBs as a percentage of their total managed assets as follows:

	Percent of Leverage
RAA	35	%
BFZ	38	%
BFO	38	%
RFA	38	%
BBF	39	%
RNJ	36	%
BNJ	36	%
RNY	35	%
BNY	37	%

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 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. Each Trust’s 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 securities at inopportune times or for distressed values, may limit the amount of appreciation a Trust can realize on an investment or may cause a Trust to hold a security 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.

	•	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.

1. Organization and Significant Accounting Policies:

BlackRock California Investment Quality Municipal Trust Inc. (“RAA”), 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. RAA, 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, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The Boards of Directors and the Boards of Trustees of the Trusts are referred to throughout this report as the “Board of Trustees” or the “Board.” The Trusts determine and make available for publication the net asset value of their Common Shares on a daily basis.

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

Valuation: The Trusts’ policy is to fair value their financial instruments at market value. 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 selected under the supervision of each Trust’s Board. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, 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 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 by a method approved by each Trust’s Board as reflecting fair value. When determining the price for such investments, 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.

Forward Commitments and When-Issued Delayed Delivery Securities: Each Trust 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 purchaser is 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 gain of the commitment, which is shown on the Schedules of Investments, if any.

Municipal Bonds Transferred to Tender Option Bond Trusts: The Trusts leverage their assets through the use of tender option bond trusts (“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 the Trust (1) to cause the holders of a proportional share of the floating rate certificates to tender their certificates at par, and (2) to transfer, within seven days, a corresponding share of the municipal bonds from the TOB to the Trusts. The TOB may also be terminated without the consent of the 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.

The cash received by the TOB from the sale of the short-term floating rate certificates, less transaction expenses, is paid to the 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 from the underlying security 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 reported as expenses of the Trusts. The 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, 2010, the aggregate value of the underlying municipal bonds

SEMI-ANNUAL REPORT JANUARY 31, 2010 55

Notes to Financial Statements (continued)

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
RAA	$	2,148,518	$	1,232,883		0.23% – 0.24	%
BFZ	$	93,961,577	$	56,378,777		0.23% – 0.34	%
BFO	$	8,919,216	$	4,573,573		0.31% – 0.48	%
RFA	$	6,515,558	$	3,504,110		0.23% – 0.53	%
BBF	$	41,590,525	$	22,228,764		0.16% – 0.27	%
RNJ	$	242,783	$	159,917		0.36	%
BNJ	$	2,063,654	$	1,359,296		0.24	%
RNY	$	117,069	$	69,974		0.24	%
BNY	$	22,677,016	$	11,549,814		0.22% – 0.31	%

For the six months ended January 31, 2010, the Trusts’ average trust certificates outstanding and the daily weighted average interest rate, including fees, were as follows:

	Average Trust Certificates Outstanding		Daily Weighted Average Interest Rate
RAA	$	1,232,883		0.74	%
BFZ	$	56,607,811		0.74	%
BFO	$	4,585,441		0.72	%
RFA	$	3,507,185		0.78	%
BBF	$	22,228,764		0.72	%
RNJ	$	159,917		0.83	%
BNJ	$	1,359,296		0.83	%
RNY	$	69,974		0.79	%
BNY	$	11,577,533		0.66	%

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

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

Segregation 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), each Trust will, consistent with SEC rules and/or certain interpretive letters issued by the SEC, segregate collateral or designate on its 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. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. Each Trust amortizes all premiums and discounts on debt securities.

Dividends and Distributions: Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. Dividends and distributions to Preferred Shareholders are accrued and determined as described in Note 6.

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

Each Trust files US federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on Investment Quality Trusts’ and Income Trusts’ US federal tax returns remain open for the periods ended July 31, 2009 and 2008 and October 31, 2007 and 2006. The statute of limitations on BFO’s US federal tax returns remain open for the periods ended July 31, 2009 and 2008 and December 31, 2007 and 2006. The statutes of limitations on the Trusts’ state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Recent Accounting Standards: In June 2009, amended guidance was issued by the Financial Accounting Standards Board (“FASB”) for transfers of financial assets. This guidance is intended to improve the relevance, representational faithfulness and comparability of the information that a reporting entity provides in its financial statements about a transfer of financial assets; the effects of a transfer on its financial position, financial performance, and cash flows; and a transferor’s continuing involvement, if any, in transferred financial assets. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after November 15, 2009. Earlier application is prohibited. The recognition and measurement provisions of this guidance must be applied to transfers occurring on or after the effective date. Additionally, the enhanced disclosure provisions of the amended guidance should be applied to transfers that occurred both before and after the effective date of this guidance. The impact of this guidance on the Trusts’ financial statements and disclosures, if any, is currently being assessed.

In January 2010, the FASB issued amended guidance to improve disclosure about fair value measurements which will require additional disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances and settlements in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). It also clarifies existing disclosure requirements relating to the levels of disaggregation for fair value measurement and inputs and valuation techniques used to measure fair value. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after December 15, 2009 except for disclosures about purchases, sales, issuances and settlements in the roll-forward of activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods

56 SEMI-ANNUAL REPORT JANUARY 31, 2010

Notes to Financial Statements (continued)

within those fiscal years. The impact of this guidance on the Trusts’ financial statements and disclosures is currently being assessed.

Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by each Trust’s Board, non-interested 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 other certain 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 other certain 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 Trust. Each Trust may, however, elect to invest in common shares of other certain 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 Funds 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. Each Fund has an arrangement with its 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.

The proposed reorganization of RAA failed to receive sufficient Common Shareholder votes to approve the reorganization. The expenses involving the proposed reorganization were charged to RAA and are shown in the Statements of Operations as reorganization costs.

2. Derivative Financial Instruments:

The Trusts may engage in various portfolio investment strategies both to increase the return of the Trusts and to economically hedge, or protect, exposure to certain risks such as interest rate risk. Losses may arise if the value of the contract decreases due to an unfavorable change in the price of the underlying instrument or if the counterparty does not perform under the contract. To the extent amounts due to the Trust from its counterparties are not fully collateralized contractually or otherwise, the Trust bears the risk of loss from counterparty non-performance. See Note 1 “Segregation and Collateralization” for information with respect to collateral practices. Counter-party risk related to exchange-traded financial futures contracts is minimal because of the protection against default provided by the exchanges on which they trade.

Financial Futures Contracts: The Trusts may 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 contracts for delayed delivery of securities at a specific future date and at a specific price or yield. 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 recognized by the Trusts as unrealized gains or losses. When the contract is closed, the Trusts record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The 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.

Derivative Instruments Categorized by Risk Exposure:

* As of January 31, 2010, there were no financial futures contracts outstanding. During the six months ended January 31, 2010, the Trusts had limited activity in these transactions.

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 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

SEMI-ANNUAL REPORT JANUARY 31, 2010 57

Notes to Financial Statements (continued)

Trust pays the Manager a monthly fee of the Trust’s average weekly net assets at the following annual rates:

RAA	0.35	%
BFZ	0.60	%
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 has contractually agreed to waive a portion of the investment advisory fee on the Income Trusts at an annual rate of 0.05% of average daily value of net assets through July 31, 2010. For the six months ended January 31, 2010, the Manager waived the following amounts, which are included in fees waived by advisor in the Statements of Operations:

	Fees Waived by Manager
BFZ	$	83,662
BBF	$	36,452
BNJ	$	40,762
BNY	$	69,840

The Manager has voluntarily agreed to waive its 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 advisory fees by the amount of investment advisory fees through its investment in other affiliated investment companies. These amounts are included in fees waived by advisor in the Statements of Operations. For the six months ended January 31, 2010, the amounts waived were as follows:

	Fees Waived by Manager
RAA	$	723
BFZ	$	7,070
BFO	$	1,870
RFA	$	224
BBF	$	2,119
RNJ	$	1,368
BNJ	$	12,237
RNY	$	429
BNY	$	2,992

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 has entered into a separate sub-advisory agreement with BlackRock Financial Management, Inc. (“BFM”), an affiliate of the Manager, with respect to each Trust, under which the Manager pays BFM for services it provides, a monthly fee that is a percentage of the investment advisory fee paid by the Trust to the Manager.

For the six months ended January 31, 2010, certain Trusts reimbursed the Manager for certain accounting services, which are included in accounting services in the Statements of Operations.

	Reimbursement
BFZ	$	3,433
BFO	$	1,246
RFA	$	17,731
BBF	$	1,515
BNJ	$	1,640
BNY	$	2,767

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.

4. Investments:

Purchases and sales of investments, excluding short-term securities, for the six months ended January 31, 2010 were as follows:

	Purchases		Sales
RAA	$	4,342,372	$	3,899,826
BFZ	$	106,890,583	$	107,502,521
BFO	$	5,612,601	$	5,619,986
RFA	$	5,332,443	$	5,630,115

RNJ	$	1,055,802	$	1,328,212
BNJ	$	8,026,965	$	2,793,136
RNY	$	4,154,857	$	3,912,938
BNY	$	25,771,166	$	21,099,426

5. Concentration, Market and Credit Risk:

Each Trust invests a substantial amount of their 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 (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 credit risk, the Trusts may be exposed to counterparty risk, or the risk that an entity with which the Trusts have unsettled or open transactions may default. Financial assets, which potentially expose the Trusts to credit and counterparty risks, consist principally of investments and cash due from counterparties. The extent of the Trusts’ exposure to credit and counterparty 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.

58 SEMI-ANNUAL REPORT JANUARY 31, 2010

Notes to Financial Statements (continued)

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

6. 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 of shares without approval of Common Shareholders. At January 31, 2010 the Common Shares owned by affiliates of the Manager for BFO was 8,028 shares.

Common Shares

During the six months ended January 31, 2010 and the year ended July 31, 2009, the shares issued and outstanding increased by the following amounts as a result of dividend reinvestment:

	Six Months Ended January 31, 2010		Year Ended July 31, 2009
BFZ		10,114		8,447
RFA		156		—
BBF		—		887
RNJ		1,237		562
BNJ		14,349		36,407
RNY		544		—
BNY		25,920		48,952

Shares issued and outstanding remained constant during the six months ended January 31, 2010 and the year ended July 31, 2009 for RAA and BFO.

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 Supplementary/Statement of Preferences/Certificate of Designation (the “Governing Instrument”), are not satisfied.

From time to time in the future, each Trust that has issued Preferred Shares may effect repurchases of such shares at prices below their liquidation preference as agreed upon by the Trust and seller. Each Trust also may redeem such 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 the 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 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 at January 31, 2010:

	Series		Preferred Shares		Effective Yield			Reset Frequency Days
RAA		W7		237		0.34	%		7
BFZ		R7		1,420		0.32	%		7
		T7		1,420		0.35	%		7
BFO		F7		1,716		0.32	%		7
RFA		R7		183		0.32	%		7
BBF		T7		1,370		0.35	%		7
RNJ		T7		276		0.35	%		7
BNJ		R7		2,364		0.32	%		7
RNY		F7		389		0.34	%		7
BNY		F7		1,890		0.34	%		7
		W7		1,890		0.34	%		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, the affected 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 AA commercial paper rate or 110% of 90% of the Kenney S&P 30-Day High Grade Index rate divided by 1.00 minus the marginal tax rate. The low, high and average

SEMI-ANNUAL REPORT JANUARY 31, 2010 59

dividend rates on the Preferred Shares for each Trust for the six months ended January 31, 2010 were as follows:

	Series		Low			High			Average
RAA		W7		0.26	%		0.55	%		0.43	%
BFZ		R7		0.24	%		0.58	%		0.43	%
		T7		0.26	%		0.55	%		0.44	%
BFO		F7		0.24	%		0.58	%		0.43	%

BBF		T7		0.26	%		0.58	%		0.44	%
RNJ		T7		0.26	%		0.58	%		0.44	%

BNY		F7		0.24	%		0.56	%		0.42	%
		W7		0.26	%		0.55	%		0.43	%

Since February 13, 2008, the Preferred Shares of each Trust 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 0.10% to 0.58% for the six months ended January 31, 2010. 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 fund’s auction rate preferred shares than buyers. A successful auction for each Trust’s 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 0.25% on the aggregate principal amount of all shares that successfully clear their auctions and 0.15% on the aggregate principal amount of all shares that fail to clear their auctions. Certain broker-dealers have individually agreed to reduce commissions for failed auctions.

During the year ended July 31, 2009, certain Trusts announced the following redemptions of Preferred Shares at a price of $25,000 per share plus any accrued and unpaid dividends through the redemption date:

	Series		Redemption Date		Shares Redeemed		Aggregate Principal
RAA		W7		7/09/09		36	$	900,000
BFZ		R7		7/10/09		598	$	14,950,000
		T7		7/08/09		598	$	14,950,000
RFA		R7		7/10/09		102	$	2,550,000
BBF		T7		7/08/09		612	$	15,300,000
RNJ		T7		7/08/09		7	$	175,000
BNJ		R7		7/10/09		55	$	1,375,000
RNY		F7		7/13/09		3	$	75,000
BNY		F7		7/13/09		27	$	675,000
		W7		7/09/09		27	$	675,000

The Trusts financed the Preferred Share redemptions with cash received from TOB transactions.

Preferred Shares issued and outstanding remained constant for the six months ended January 31, 2010 for all Trusts.

The Trusts’ distribution rates declared on March 1, 2010 were as follows:

	Per Common Share Amount
RNJ	$	0.065500
RNY	$	0.070700

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, the “Target Fund”) approved the reorganizations of BCK, BZA and BCL into BFZ, pursuant to which BFZ acquired substantially all of the assets and assumed substantially all of the liabilities of BCK, BZA and BCL in exchange for an equal aggregate value of newly-issued Common and Preferred Shares of BFZ.

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.

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 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		0.97546003		5,148,563
BZA		3,409,668		1.04505055		3,563,275
BCL		7,999,789		0.99301767		7,943,932
	Preferred Shares
	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 were as follows:

	Net Assets Applicable to Common Shareholders		Preferred Shares at Liquidation Preference		Paid-In Capital		Net Investment Income		Net Realized Loss			Net Unrealized Appreciation/ Depreciation
BCK	$	70,787,683	$	31,325,000	$	74,691,531	$	45,388	$	(2,517,190	)	$	(1,432,046	)
BZA	$	48,991,313	$	22,450,000	$	48,265,052	$	19,676	$	(560,343	)	$	1,266,928
BCL	$	109,221,113	$	46,550,000	$	113,334,256	$	71,219	$	(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 was as follows:

	Fair Value of Investments		Cost of Investments
BCK	$	97,202,618	$	98,634,664
BZA	$	69,163,964	$	67,897,036
BCL	$	152,275,812	$	149,208,557

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. In addition to this reduction, BFZ’s contractual investment advisory fee waiver was extended for an additional two years through December 31, 2012 as follows: (i) 0.05% in 2010, (ii) 0.03% in 2011 and (iii) 0.01% in 2012.

Additional Information (continued)

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.

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.
