Dear Shareholder

Although overall global economic and financial conditions have generally improved over the past year, the past several months have seen high levels of market volatility and diminishing investor confidence sparked by the sovereign debt crisis in Europe and mixed economic data that have raised concerns over the possibility that some economies could slide back into recession. Despite the uneven nature of recent market conditions, we continue to believe that the “Great Recession” likely ended at some point last summer, thanks primarily to massive fiscal and monetary stimulus, and that the global economy remains in recovery mode for most regions of the world. Regarding the US economy, we believe it is unlikely that the United States will experience a “double dip” recession, although we acknowledge that subpar growth is likely to persist for some time.

Global equity markets bottomed in early 2009 and since that time have moved unevenly higher as investors were lured back into the markets by depressed valuations, desire for higher yields and improvements in corporate earnings prospects. Volatility levels, however, have remained elevated — primarily as a result of uneven economic data and lingering deflation issues (especially in Europe). As the period drew to a close, equity markets had endured a significant correction that drove stock prices into negative territory on a year-to-date basis in almost every market. Over a 12-month basis, however, global equities posted positive returns thanks to improving corporate revenues and profits and a reasonably strong macro backdrop. From a geographic perspective, US equities have significantly outpaced their international counterparts over the past six and twelve months, as the domestic economic recovery has been more pronounced and as credit-related issues have held European markets down. Within the United States, smaller cap stocks have noticeably outperformed large caps.

In fixed income markets, yields have been moving unevenly over the past six and twelve months as improving economic conditions have been acting to push Treasury yields higher (and prices correspondingly lower), while concerns over ongoing deflation threats have acted as a counterweight. As the period drew to a close, however, Treasury yields fell sharply as investors flocked to the “safe haven” asset class in the face of escalating uncertainty. As a result, US Treasuries became one of the world’s best-performing asset classes on a six-month basis. High yield bonds have also continued to perform well, thanks in large part to ongoing high levels of investor demand. Meanwhile, municipal bonds performed in line with their taxable counterparts on a 12-month basis, but slightly underperformed over the last six months as investors rotated to the relative safety of Treasuries.

Regarding cash investments, yields on money market securities remain near all-time lows (producing returns only marginally above zero percent), with the Federal Open Market Committee reiterating that economic circumstances are likely to necessitate an accommodative interest rate stance for an “extended period.”

Against this backdrop, the major market averages posted the following returns:

Total Returns as of June 30, 2010	6-month		12-month
US equities (S&P 500 Index)	(6.65	)%	14.43	%
Small cap US equities (Russell 2000 Index)	(1.95	)	21.48
International equities (MSCI Europe, Australasia, Far East Index)	(13.23	)	5.92
3-month Treasury bill (BofA Merrill Lynch 3-Month Treasury Bill Index)	0.05		0.16
US Treasury securities (BofA Merrill Lynch 10-Year US Treasury Index)	9.36		8.20
Taxable fixed income (Barclays Capital US Aggregate Bond Index)	5.33		9.50
Tax-exempt fixed income (Barclays Capital Municipal Bond Index)	3.31		9.61
High yield bonds (Barclays Capital US Corporate High Yield 2% Issuer Capped Index)	4.45		26.66

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

Although conditions are certainly better than they were a couple of years ago, global financial markets continue to face high volatility and questions about the strength and sustainability of the recovery abound.

Trust Summary as of June 30, 2010 BlackRock California Municipal 2018 Term Trust

Investment Objective and Overview

BlackRock California Municipal 2018 Term Trust’s (BJZ) (the “Trust”) investment objective is to seek to provide monthly income that is exempt from regular federal and California income taxes and to return $15 per share (the initial offering price) to investors on or about December 31, 2018. The Trust seeks to achieve its investment objective by investing at least 80% of its total assets in municipal bonds that at the time of investment are investment grade quality.

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

For the six months ended June 30, 2010, the Trust returned 5.49% based on market price and 5.41% based on net asset value (“NAV”). The Trust’s peer group of closed-end funds in the Lipper California Municipal Debt Funds category posted an average return of 10.90% based on market price and 5.24% based on NAV for the same period. 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 market price and performance based on NAV. The Trust is scheduled to mature on or about December 31, 2018. For that reason, the Trust invests in issues generally shorter in maturity than its peers in the Lipper category. The Trust benefited from its positioning in intermediate-term issues, which outperformed issues on the longer end of the yield curve. The Trust’s exposure to pre-refunded and escrowed issues detracted from performance.

Trust Summary as of June 30, 2010 BlackRock Insured Municipal Term Trust Inc.

Investment Objective and Overview

BlackRock Insured Municipal Term Trust Inc.’s (BMT) (the “Trust”) investment objective is to seek to provide monthly income that is exempt from regular federal income tax and to return $10 per share (the initial offering price) to investors on or about December 31, 2010. The Trust seeks to achieve its investment objective by investing at least 80% of its total assets in diversified portfolio of municipal bonds insured as to the timely payment of both principal and interest.

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

For the six months ended June 30, 2010, the Trust returned (2.39)% based on market price and 0.10% based on NAV. The Trust’s peer group of closed-end funds in the Lipper General Municipal Debt Funds (Leveraged) category posted an average return of 9.55% based on market price and 5.76% based on NAV for the same period. All returns reflect reinvestment of dividends. The Trust moved from a premium to NAV to a discount by period end, which accounts for the difference between performance based on market price and performance based on NAV. The Trust is scheduled to mature on or about December 31, 2010, and therefore owns bonds that mature near this date. The short-term nature of such issues does not allow for comparable performance relative to peer group funds holding longer-term issues that generally experience price appreciation during periods of declining interest rates. To mitigate market risk prior to the Trust’s termination, we have begun liquidating securities with maturities beyond the termination date. As of period end, approximately 57% of the Trust’s net assets were in cash and cash equivalents, which detracted from performance in the low short-term interest rate environment. However, the Trust benefited from high book yields on its longer held issues with maturities prior to the termination date.

SEMI-ANNUAL REPORT JUNE 30, 2010 7

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, certain 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 financing 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 Preferred Shares issuance earn 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 rates 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 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 NAVs 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’ 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, each Trust’s net income will be less than if leverage had not been used, and therefore the amount available for distribution to Common Shareholders will be reduced. 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 June 30, 2010, the following Trusts had economic leverage from Preferred Shares and/or TOBs as a percentage of their total managed assets as follows:

	•	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 Insured Municipal Term Trust Inc. (“BMT”), is organized as a Maryland corporation. BlackRock Municipal 2018 Term Trust (“BPK”), BlackRock California Municipal 2018 Term Trust (“BJZ”) and BlackRock New York Municipal 2018 Term Trust (“BLH”) are organized as Delaware statutory trusts. BMT and BPK are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as diversified, closed-end management investment companies. BJZ and BLH are registered as non-diversified, closed-end management investment companies under the 1940 Act. BPK, BJZ and BLH are herein referred to as the “2018 Trusts.” BMT and the 2018 Trusts are referred to herein collectively as the “Trusts” or individually as a “Trust.” 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 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.

BMT will terminate on or about December 31, 2010.

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 using independent dealers or pricing services selected under the supervision of 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. 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 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 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 counterparty, 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.

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 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.

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 Trust’s 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.

28 SEMI-ANNUAL REPORT JUNE 30, 2010

Notes to Financial Statements (continued)

Interest income 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 June 30, 2010, the aggregate value of the underlying municipal bonds transferred to TOBs, the related liability for trust certificates and the interest rate on the liability for trust certificates were as follows:

	Underlying Municipal Bonds Transferred to TOBs		Liability for Trust Certificates		Interest Rate
BPK	$	5,522,750	$	3,750,000		0.36	%

For the six months ended June 30, 2010, the Trust’s 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
BPK	$	3,750,000		0.66	%

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

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.

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, including amortization of premium and accretion of discount on debt securities, is recognized on the accrual basis.

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 6.

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.

The Trusts file US federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Trusts’ US federal tax returns remains open for each of the four years ended December 31, 2009. The statutes of limitations on the Trusts’ state and local tax returns may remain open for an additional year depending upon the jurisdiction. There are no uncertain tax positions that require recognition of a tax liability.

Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by each 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 thereunder 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 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. 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, and 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:

BJZ	0.40	%
BMT	0.35	%
BPK	0.40	%
BLH	0.40	%

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

The Manager 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 paid through its investment in other affiliated investment companies, if any. This amount is shown as fees waived by advisor in the Statements of Operations.

The Manager entered into a separate sub-advisory agreement with BlackRock Financial Management, Inc. (“BFM”), an affiliate of the Manager, with respect to the 2018 Trusts. The Manager pays BFM for services it provides, a monthly fee that is a percentage of the investment advisory fees paid by the 2018 Trusts to the Manager.

The administration fee paid to the Manager by BMT is computed weekly and payable monthly based on an annual rate of 0.10% of the Trust’s average weekly net assets.

For the six months ended June 30, 2010, the 2018 Trusts reimbursed the Manager for certain accounting services, which are included in accounting services in the Statements of Operations. The reimbursements were as follows:

BJZ	$	1,323
BPK	$	3,278
BLH	$	800

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.

3. Investments:

Purchases and sales of investments excluding short-term securities for the six months ended June 30, 2010, were as follows:

	Purchases		Sales
BJZ	$	9,195,199	$	11,435,194
BMT	$	1,539,661	$	103,375,800
BPK	$	12,775,948	$	6,264,728
BLH	$	3,072,954	$	2,525,478

4. Capital Loss Carryforwards:

As of December 31, 2009, the Trusts had capital loss carryforwards available to offset future realized capital gains through the indicated expiration dates:

Expires December 31,	BJZ		BMT		BPK		BLH

Total	$	4,077,582	$	2,615	$	14,264,806	$	1,154,301

5. Concentration, Market and Credit Risk:

BJZ and BLH invest 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.

30 SEMI-ANNUAL REPORT JUNE 30, 2010

Notes to Financial Statements (continued)

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 counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the 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.

BJZ invests a significant portion of its assets in securities in the county/city/special district/school district sector. BMT invests a significant portion of its assets in securities in the county/city/special district/school district and utilities sectors. BPK invests a significant portion of its assets in securities in the corporate sector. BLH invests a significant portion of its assets in securities in the county/city/special district/school district and education sectors. Changes in economic conditions affecting these 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:

BMT is authorized to issue 200 million shares, including Preferred Shares, all of which were initially classified as Common Shares, par value $0.01 per share. The 2018 Trusts are authorized to issue an unlimited number of shares, including Preferred Shares, par value $0.001 per share, all of which were initially classified as Common Shares. Each Board is authorized, however, to reclassify any unissued shares without approval of Common Shareholders.

Shares issued and outstanding remained constant for the Trusts for the six months ended June 30, 2010 and the years ended December 31, 2009 and December 31, 2008.

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 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 2018 Trusts had the following series of Preferred Shares outstanding, effective yields and reset frequency as of June 30, 2010:

	Series	Preferred Shares	Effective Yield	Reset Frequency Days
BJZ	M7	2,221	0.46%	7
BPK	W7	2,677	0.47%	7
	R7	2,677	0.46%	7
BLH	T7	1,256	0.40%	7

SEMI-ANNUAL REPORT JUNE 30, 2010 31

Notes to Financial Statements (concluded)

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 divided by 1.00 minus the marginal tax rate. The low, high and average dividend rates on the Preferred Shares for each 2018 Trust for the six months ended June 30, 2010 were as follows:

	Series	Low	High	Average
BJZ	M7	0.24%	0.50%	0.39%
BPK	W7	0.26%	0.50%	0.39%
	R7	0.24%	0.49%	0.40%
BLH	T7	0.26%	0.50%	0.39%

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 0.24% to 0.50% for the six months ended June 30, 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 Trust’s auction rate preferred shares than buyers. It is impossible to predict how long this imbalance will last. A successful auction for the Trusts’ Preferred Shares may not occur for some time, if ever, and even if liquidity does resume, holders of the Preferred Shares 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.

Preferred Shares issued and outstanding remained constant during the six months ended June 30, 2010 and the year ended December 31, 2009 for all Trusts. Preferred Shares issued and outstanding remained constant for BJZ and BLH for the year ended December 31, 2008.

During the year ended December 31, 2008, BMT and BPK 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
BMT	M7	6/24/08	600	$	15,000,000
	M7	11/18/08	2,000	$	50,000,000
BPK	W7	6/26/08	75	$	1,875,000
	R7	6/27/08	75	$	1,875,000

BMT had sufficient short-term securities to satisfy the redemptions. The 2018 Trusts financed the Preferred Share redemptions with cash received from TOB transactions.

7. 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:

Each Trust paid a net investment income dividend on August 2, 2010 to Common Shareholders of record on July 15, 2010 as follows:

	Common Dividend Per Share
BJZ	$ 0.072
BMT	$ 0.015
BPK	$ 0.078
BLH	$ 0.082

The dividends declared on Preferred Shares for the period July 1, 2010 to July 31, 2010 were as follows:

	Series	Dividends Declared
BJZ	M7		$	19,346
BPK	W7		$	23,676
	R7		$	23,037
BLH	T7		$	10,946

On August 2, 2010, BMT declared a dividend to Common Shareholders of record on August 16, 2010 of $0.0050 per share.

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements

The Board of Trustees (each, a “Board,” collectively, the “Boards,” and the members of which are referred to as “Board Members”) of BlackRock New York Municipal 2018 Term Trust (“BLH”), BlackRock California Municipal 2018 Term Trust (“BJZ”), The BlackRock Insured Municipal Term Trust Inc. (“BMT”) and BlackRock Municipal 2018 Term Trust (“BPK” and together with BLH, BJZ and BMT, each a “Fund,” and, collectively, the “Funds”) met on April 8, 2010 and May 13 – 14, 2010 to consider the approval of each Fund’s investment advisory agreement (each, an “Advisory Agreement”) with BlackRock Advisors, LLC (the “Manager”), each Fund’s investment advisor. The Boards of BLH, BJZ and BPK also considered the approval of the sub-advisory agreement (each, a “Sub-Advisory Agreement”) between the Manager and BlackRock Financial Management, Inc. (the “Sub-Advisor”) with respect to each Fund. The Manager and the Sub-Advisor are referred to herein as “BlackRock.” The Advisory Agreements and the Sub-Advisory Agreements are referred to herein as the “Agreements.”

Activities and Composition of the Board

The Board of each Fund consists of ten individuals, eight of whom are not “interested persons” of such Fund as defined in the Investment Company Act of 1940 (the “1940 Act”) (the “Independent Board Members”). The Board Members are responsible for the oversight of the operations of each Fund and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Board Members have retained independent legal counsel to assist them in connection with their duties. The Chairman of the Boards is an Independent Board Member. The Boards have established five standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee and an Executive Committee, each of which is composed of Independent Board Members (except for the Executive Committee, which also has one interested Board Member) and is chaired by an Independent Board Member. The Board of BMT also has one ad hoc committee, the Joint Product Pricing Committee, which consists of Independent Board Members and the directors/trustees of the boards of certain other BlackRock-managed funds, who are not “interested persons” of their respective funds. The Boards of BJZ, BPK and BLH have two ad hoc committees, the Joint Product Pricing Committee, which consists of Independent Board Members and the directors/trustees of the boards of certain other BlackRock-managed funds, who are not “interested persons” of their respective funds, and the Ad Hoc Committee on Auction Market Preferred Shares.

The Agreements

Pursuant to the 1940 Act, the Boards are required to consider the continuation of the Agreements on an annual basis. In connection with this process, the Boards assessed, among other things, the nature, scope and quality of the services provided to the Funds by the personnel of BlackRock and its affiliates, including investment management, administrative and shareholder services, oversight of fund accounting and custody, marketing services and assistance in meeting applicable legal and regulatory requirements.

From time to time throughout the year, each Board, acting directly and through its committees, considered at each of its meetings factors that are relevant to its annual consideration of the renewal of the Agreements, including the services and support provided by BlackRock to the respective Fund and its shareholders. Among the matters the Board considered were: (a) investment performance for one-, three- and five-year periods, as applicable, against peer funds, and applicable benchmarks, if any, as well as senior management and portfolio managers’ analysis of the reasons for any over performance or underperformance against a Fund’s peers and/or benchmark, as applicable; (b) fees, including advisory, and administration for BMT, and other amounts paid to BlackRock and its affiliates by each Fund for services such as call center and fund accounting; (c) each Fund’s operating expenses; (d) the resources devoted to and compliance reports relating to each Fund’s investment objective, policies and restrictions; (e) each Fund’s compliance with its Code of Ethics and compliance policies and procedures; (f) the nature, cost and character of non-investment management services provided by BlackRock and its affiliates; (g) BlackRock’s and other service providers’ internal controls; (h) BlackRock’s implementation of the proxy voting policies approved by the Boards; (i) execution quality of portfolio transactions; (j) BlackRock’s implementation of each Fund’s valuation and liquidity procedures; (k) an analysis of contractual and actual management fees for products with similar investment objectives across the open-end fund, closed-end fund and institutional account product channels; and (l) periodic updates on BlackRock’s business.

Board Considerations in Approving the Agreements

The Approval Process: Prior to the April 8, 2010 meeting, the Boards requested and received materials specifically relating to the Agreements. The Boards are engaged in a process with BlackRock to periodically review the nature and scope of the information provided to better assist their deliberations. The materials provided in connection with the April meeting included: (a) information independently compiled and prepared by Lipper, Inc. (“Lipper”) on Fund fees and expenses, and the investment performance of each Fund as compared with a peer group of funds as determined by Lipper (collectively, “Peers”); (b) information on the profitability of the Agreements to BlackRock and a discussion of fall-out benefits to BlackRock and its affiliates and significant shareholders; (c) a general analysis provided by BlackRock concerning investment advisory fees charged to other clients, such as institutional clients and open-end funds, under similar investment mandates; (d) the impact of economies of scale; (e) a summary of aggregate amounts paid by each Fund to BlackRock; and (f) if applicable, a comparison of management fees to similar BlackRock closed-end funds, as classified by Lipper.

At an in-person meeting held on April 8, 2010, the Boards reviewed materials relating to their consideration of the Agreements. As a result of the discussions that occurred during the April 8, 2010 meeting, the Boards presented BlackRock with questions and requests for additional information and BlackRock responded to these requests with additional written information in advance of the May 13 – 14, 2010 Board meeting.

At an in-person meeting held on May 13 – 14, 2010, each Fund’s Board, including the Independent Board Members, unanimously approved the continuation of the Advisory Agreement between the Manager and each of BJZ, BPK and BLH for a one year term ending June 30, 2011 and between the Manager and BMT for a term ending upon the termination of BMT, which is scheduled to occur on or about December 31, 2010. The Boards of BJZ, BPK and BLH unanimously approved the continuation of the Sub-Advisory Agreement between the Manager and the Sub-Advisor with respect to each Fund, each for a one-year term ending June 30, 2011. In approving the continuation of the Agreements, the Boards considered: (a) the nature, extent and quality of the services provided by BlackRock; (b) the investment performance of each Fund and BlackRock; (c) the advisory fee and the cost of the services and profits to be realized by BlackRock and its affiliates from their relationship with each Fund; (d) economies of scale; and (e) other factors deemed relevant by the Board Members.

The Boards also considered other matters they deemed important to the approval process, such as services related to the valuation and pricing of each Fund’s portfolio holdings, direct and indirect benefits to BlackRock and its affiliates and significant shareholders from their relationship with each Fund and advice from independent legal counsel with respect to the review process and materials submitted for the Boards’ review. The Boards noted the willingness of BlackRock personnel to engage in open, candid discussions with the Boards. The Boards did not identify any particular information as controlling, and each Board Member may have attributed different weights to the various items considered.

A. Nature, Extent and Quality of the Services Provided by BlackRock: The Boards, including the Independent Board Members, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services and the resulting performance of each Fund. Throughout the year, the Boards compared each Fund’s performance to the performance of a comparable group of closed-end funds, and the performance of a relevant benchmark, if any. The Boards met with BlackRock’s senior management personnel responsible for investment operations, including the senior investment officers. The Boards also reviewed the materials provided by each Fund’s portfolio management team discussing each Fund’s performance and each Fund’s investment objective, strategies and outlook.

The Boards considered, among other factors, the number, education and experience of BlackRock’s investment personnel generally and each Fund’s portfolio management team, investments by portfolio managers in the funds they manage, BlackRock’s portfolio trading capabilities, BlackRock’s use of technology, BlackRock’s commitment to compliance and BlackRock’s approach to training and retaining portfolio managers and other research, advisory and management personnel. The Boards also reviewed a general description of BlackRock’s compensation structure with respect to each Fund’s portfolio management team and BlackRock’s ability to attract and retain high-quality talent.

In addition to advisory services, the Boards considered the quality of the administrative and non-investment advisory services provided to each Fund. BlackRock and its affiliates and significant shareholders provide each Fund with certain administrative and other services (in addition to any such services provided to each Fund by third parties) and officers and other personnel as are necessary for the operations of each Fund. In addition to investment advisory services, BlackRock and its affiliates provide each Fund with other services, including: (i) preparing disclosure documents, such as the prospectus and the statement of additional information in connection with the initial public offering and periodic shareholder reports; (ii) preparing communications with analysts to support secondary market trading of each Fund; (iii) assisting with daily accounting and pricing; (iv) preparing periodic filings with regulators and stock exchanges; (v) overseeing and coordinating the activities of other service providers; (vi) organizing Board meetings and preparing the materials for such Board meetings; (vii) providing legal and compliance support; and (viii) performing other administrative functions necessary for the operation of each Fund, such as tax reporting, fulfilling regulatory filing requirements, and call center services. The Boards reviewed the structure and duties of BlackRock’s fund administration, accounting, legal and compliance departments and considered BlackRock’s policies and procedures for assuring compliance with applicable laws and regulations.

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (continued)

B. The Investment Performance of the Funds and BlackRock: The Boards, including the Independent Board Members, also reviewed and considered the performance history of each Fund. In preparation for the April 8, 2010 meeting, the Boards were provided with reports, independently prepared by Lipper, which included a comprehensive analysis of each Fund’s performance. The Boards also reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock, which analyzed various factors that affect Lipper’s rankings. In connection with their review, the Boards received and reviewed information regarding the investment performance of each Fund as compared to a representative group of similar funds as determined by Lipper and to all funds in each Fund’s applicable Lipper category. The Boards were provided with a description of the methodology used by Lipper to select peer funds. The Boards regularly review the performance of each Fund throughout the year.

The Board of BPK noted that, in general, BPK performed better than its Peers in that BPK’s performance was at or above the median of its Lipper Performance Composite in each of the one-, three- and five-year periods reported.

The Board of each of BJZ and BLH noted that, in general, BJZ and BLH performed better than their respective Peers in that the performance of each of BJZ and BLH was at or above the median of their respective Lipper Performance Composite in two of the one-, three- and five-year periods reported.

The Board of BMT noted that BMT performed below the median of its Lipper Performance Composite in each of the one-, three- and five-year periods reported. The Board of BMT and BlackRock reviewed the reasons for BMT’s underperformance during these periods compared with its Peers. The Board of BMT was informed that, among other things, BMT has a targeted maturity, and as such is managed to achieve the specific maturity goal.

The Board noted that BlackRock has made changes to the organization of the overall fixed income group management structure designed to result in a strengthened leadership team with clearer accountability.

C. Consideration of the Advisory Fees and the Cost of the Services and Profits to be Realized by BlackRock and its Affiliates from their Relationship with the Funds: The Boards, including the Independent Board Members, reviewed each Fund’s contractual advisory fee rates compared with the other funds in its Lipper category. The Boards also compared each Fund’s total expenses, as well as actual management fees, to those of other funds in its Lipper category. The Boards considered the services provided and the fees charged by BlackRock to other types of clients with similar investment mandates, including separately managed institutional accounts.

The Boards received and reviewed statements relating to BlackRock’s financial condition and profitability with respect to the services it provided each Fund. The Boards were also provided with a profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to each Fund. The Boards reviewed BlackRock’s profitability with respect to each Fund and other funds the Boards currently oversee for the year ended December 31, 2009 compared to available aggregate profitability data provided for the year ended December 31, 2008. The Boards reviewed BlackRock’s profitability with respect to other fund complexes managed by the Manager and/or its affiliates. The Boards reviewed BlackRock’s assumptions and methodology of allocating expenses in the profitability analysis, noting the inherent limitations in allocating costs among various advisory products. The Boards recognized that profitability may be affected by numerous factors including, among other things, fee waivers and expense reimbursements by the Manager, the types of funds managed, expense allocations and business mix, and the difficulty of comparing profitability as a result of those factors.

The Boards noted that, in general, individual fund or product line profitability of other advisors is not publicly available. Nevertheless, to the extent such information was available, the Boards considered BlackRock’s overall operating margin, in general, compared to the operating margin for leading investment management firms whose operations include advising closed-end funds, among other product types. That data indicates that operating margins for BlackRock with respect to its registered funds are generally consistent with margins earned by similarly situated publicly traded competitors. In addition, the Boards considered, among other things, certain third party data comparing BlackRock’s operating margin with that of other publicly traded asset management firms. That third party data indicates that larger asset bases do not, in themselves, translate to higher profit margins.

In addition, the Boards considered the cost of the services provided to each Fund by BlackRock, and BlackRock’s and its affiliates’ profits relating to the management and distribution of each Fund and the other funds advised by BlackRock and its affiliates. As part of their analysis, the Boards reviewed BlackRock’s methodology in allocating its costs to the management of each Fund. The Boards also considered whether BlackRock has the financial resources necessary to attract and retain high-quality investment management personnel to perform its obligations under the Agreements and to continue to provide the high quality of services that is expected by the Boards.

The Board of each of BJZ, BPK and BLH noted that the contractual management fee rate was lower than or equal to the median contractual management fee rate paid by their respective Peers, in each case, before taking into account any expense reimbursements or fee waivers.

SEMI-ANNUAL REPORT JUNE 30, 2010 35

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (concluded)

The Board of BMT noted that BMT’s contractual management fee rate was above the median contractual management fee rate paid by BMT’s Peers, in each case, before taking into account any expense reimbursements or fee waivers. The Board of BMT also noted, however, that BMT’s actual management fee rate, after giving effect to any expense reimbursements or fee waivers by BlackRock, was lower than or equal to the median actual management fee rate paid by BMT’s Peers, after giving effect to any expense reimbursements or fee waivers.

D. Economies of Scale: The Boards, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of each Fund increase. The Boards also considered the extent to which each Fund benefits from such economies and whether there should be changes in the advisory fee rate or structure in order to enable each Fund to participate in these economies of scale, for example through the use of breakpoints in the advisory fee based upon the asset level of each Fund.

The Boards noted that most closed-end fund complexes do not have fund level breakpoints because closed-end funds generally do not experience substantial growth after the initial public offering and each fund is managed independently consistent with its own investment objectives. The Boards noted that only one closed-end fund in the Fund Complex has breakpoints in its fee structure. Information provided by Lipper also revealed that only one closed-end fund complex with total closed-end fund net assets exceeding $10 billion, as of December 31, 2009, used a complex level breakpoint structure.

E. Other Factors Deemed Relevant by the Board Members: The Boards, including the Independent Board Members, also took into account other ancillary or “fall-out” benefits that BlackRock or its affiliates and significant shareholders may derive from their respective relationships with the Funds, both tangible and intangible, such as BlackRock’s ability to leverage its investment professionals who manage other portfolios, an increase in BlackRock’s profile in the investment advisory community, and the engagement of BlackRock’s affiliates and significant shareholders as service providers to each Fund, including for administrative and distribution services. The Boards also considered BlackRock’s overall operations and its efforts to expand the scale of, and improve the quality of, its operations. The Boards also noted that BlackRock may use and benefit from third party research obtained by soft dollars generated by certain mutual fund transactions to assist in managing all or a number of its other client accounts. The Boards further noted that BlackRock completed the acquisition of a complex of exchange-traded funds (“ETFs”) on December 1, 2009, and that BlackRock’s funds may invest in such ETFs without any offset against the management fees payable by the funds to BlackRock.

In connection with its consideration of the Agreements, the Boards also received information regarding BlackRock’s brokerage and soft dollar practices. The Boards received reports from BlackRock which included information on brokerage commissions and trade execution practices throughout the year.

The Boards noted the competitive nature of the closed-end fund marketplace, and that shareholders are able to sell their respective Fund’s shares in the secondary market if they believe that the Fund’s fees and expenses are too high or if they are dissatisfied with the performance of the Fund.

Conclusion

The Boards, including the Independent Board Members, unanimously approved the continuation of the Advisory Agreement between the Manager and each of BJZ, BPK and BLH for a one year term ending June 30, 2011 and between the Manager and BMT for a term ending upon the termination of BMT, which is scheduled to occur on or about December 31, 2010. The Boards of BJZ, BPK and BLH unanimously approved the continuation of the Sub-Advisory Agreement between the Manager and the Sub-Advisor with respect to each Fund, each for a one-year term ending June 30, 2011. As part of its approval, the Boards considered the detailed review of BlackRock’s fee structure, as it applies to its respective Fund, being conducted by the ad hoc Joint Product Pricing Committee. Based upon its evaluation of all of the aforementioned factors in their totality, the Boards, including the Independent Board Members, were satisfied that the terms of the Agreements were fair and reasonable and in the best interest of each Fund and its shareholders. In arriving at a decision to approve the Agreements, the Boards did not identify any single factor or group of factors as all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination. The contractual fee arrangements for each Fund reflect the results of several years of review by the Board Members and predecessor Board Members, and discussions between such Board Members (and predecessor Board Members) and BlackRock. Certain aspects of the arrangements may be the subject of more attention in some years than in others, and the Board Members’ conclusions may be based in part on their consideration of these arrangements in prior years.

SEMI-ANNUAL REPORT JUNE 30, 2010 37

Additional Information

General Information

On August 11, 2010, BlackRock Advisors, LLC, the Trusts’ investment advisor (the “Manager”), announced that BMT received a demand letter from a law firm on behalf of BMT’s common shareholders. The demand letter alleges that the Manager and BMT’s officers and Board of Directors (the “Board”) breached their fiduciary duties related to the redemption at par of certain of the BMT’s Preferred Shares. The independent Directors are currently evaluating the demand letter for BMT.

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

During the period, there were no material changes in the Trusts’ investment objectives or policies or to the Trusts’ charters or by-laws that were not approved by the shareholders or in the principal risk factors associated with investment in the Trusts. There have been no changes in the persons who are primarily responsible for the day-to-day management of the Trusts’ portfolio.

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

Electronic Delivery

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

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

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

Householding

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

Availability of Quarterly Portfolio Schedule of Investments

Each Trust files its complete schedule of portfolio holdings with the Securities and Exchange Commission (the “SEC”) for the first and third quarters of each fiscal year on Form N-Q. The Trusts’ Forms N-Q are available on the SEC’s website at http://www.sec.gov and may also be reviewed and copied at the SEC’s Public Reference Room in Washington, DC. Information on the operation of the Public Reference Room may be obtained by calling (800) SEC-0330. Each Trust’s Forms N-Q may also be obtained upon request and without charge by calling (800) 441-7762.

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. BPK, BJZ and BLH leverage 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 the 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.
