-------------------------------------------------------------------------------- BLACKROCK MUNICIPAL 2018 TERMTRUST SEMI-ANNUAL REPORT TO SHAREHOLDERS REPORT OF INVESTMENT ADVISOR -------------------------------------------------------------------------------- July 31, 2002 Dear Shareholder: The semi-annual period ended June 30, 2002, saw general turmoil in the equity markets. Bond markets, particularly municipal securities, proved to be a viable shelter from unstable economic conditions and experienced strong inflows throughout the period. Municipal bonds outperformed Treasuries returning 4.64% versus 3.61% respectively as measured by the Lehman Brothers Municipal Bond Index* and the Lehman Brothers Treasury Index** for the six months ended June 30, 2002. The first half of 2002 was markedly different from the last six months of 2001, as the Federal Reserve Board (the "Fed") left interest rates unchanged. After a 225 basis point decline in interest rates during the latter half of 2001, and the uncertainty of the economic recovery in the first half of this year, the Fed remained cautious about the state of the economy. Fears of inflation remained subdued, allowing the Fed to remain on hold and maintain the lowest interest rates in decades. The past six months also saw a 20% increase in new municipal issuance totaling $162 billion, as compared to the same time period last year. Both retail and institutional investment in municipals remained high and continued to drive performance as investors sought lower volatility alternatives with attractive taxable equivalent yields. While economic indicators remained positive during the period, the instability of the equity and capital markets--as a result of corporate governance and accounting issues, fears of renewed terrorist acts and geopolitical instability--weighed on investor confidence, an integral component of economic recovery. The volatility, which continues to be seen throughout all sectors of the market, can be disconcerting for investors. We encourage you to consult with your financial advisor to help establish a strategy that best fits your overall goals and risk tolerance. The semi-annual report includes a summary of market conditions over the last six months, a review of the strategy employed by your Trust's portfolio managers, the Trust's unaudited financial statements and a listing of the portfolio's holdings. We thank you for your continued confidence in BlackRock and the opportunity to help you achieve your long-term investment goals. Sincerely, /s/ Laurence D. Fink /s/ Ralph L. Schlosstein Laurence D.

The Index is unmanaged and cannot be purchased directly. 1 July 31, 2002 Dear Shareholder: We are pleased to present the first unaudited semi-annual report for the BlackRock Municipal 2018 Term Trust (the "Trust") for the six months ended June 30, 2002. We would like to take this opportunity to review the change in the Trust's stock price and net asset value (NAV), summarize developments in the fixed income markets and discuss recent portfolio management activity. The Trust is a diversified closed-end bond fund whose shares are traded on the New York Stock Exchange under the symbol "BPK." The Trust's investment objectives are to provide current income that is exempt from regular Federal income tax and to return $15 per share (an amount equal to the Trust's initial public offering price) to investors on or about December 31, 2018. The Trust will invest at least 80% of its total assets in municipal bonds that at the time of investment are investment grade quality (rated "Baa" or "BBB" or better by a major rating agency or of equivalent quality). The Trust may invest up to 20% of its total assets in municipal bonds that at the time of investment are non-investment grade (rated "Ba/BB" or "B" by a major rating agency or of equivalent quality). The table below summarizes the changes in the Trust's share price and NAV: -------------------------------------------------------------------------------- 06/30/02 12/31/01 CHANGE HIGH LOW -------------------------------------------------------------------------------- Share Price $13.50 $13.06 3.37% $14.02 $12.98 -------------------------------------------------------------------------------- Net Asset Value (NAV) $14.39 $13.66 5.34% $14.43 $13.71 -------------------------------------------------------------------------------- THE FIXED INCOME MARKETS Economic performance was mixed during the semi-annual period ended June 30, 2002, as volatility and instability were prevalent throughout all sectors of the market. The U.S. economy showed signs of recovery, but mixed economic data and dismal performance in the equity markets caused a massive unwinding of Fed tightening expectations. Structural imbalances in the U.S. economy became evident and the effects of the short-term stimulus post September 11th diminished, causing the Fed to remain on hold and leave the Federal Funds rate unchanged at 1.75%. Positive economic data included a rise in first quarter 2002 GDP of 6.1%, the fastest rate in two years, strong manufacturing data, an 8.4% rise in first quarter 2002 productivity and the Consumer Confidence Index advancing from year-end levels. Low inventory levels should support manufacturing data, but we are skeptical about the continued strength of consumer demand, which is essential to a sustained economic recovery. The long-term sustainability of the highly leveraged consumer remains a pivotal issue to the strength of the economic recovery. Although fundamentals support a recovery, declining equities and a plummeting dollar continue to erode investor confidence. We remain uncertain that a near-term business investment recovery will materialize, as pricing power remains weak. While second quarter weakness may be overstated, the likely outcome is one of several quarters of sub-par growth in the 2.5%-3.0% range. Year-to-date, rates have fallen across the yield curve. The Treasury market returned 3.61% during the period, posting exceptionally strong months in April and June as risk aversion dominated the markets. Over the course of the period, the yield curve steepened in reaction to mixed economic data and a proliferation of negative headlines in the corporate sector. Looking ahead, the budget surplus of 2001 is unlikely to be sustained due to anemic tax revenues and a sharp rise in defense spending, which should result in larger auction sizes. However, the allowable debt limit set by Congress will soon be reached, possibly leading the Treasury to pursue additional methods of financing until it can return to regular auctions. As of June 30, 2002, the 10-year Treasury was yielding 4.80% versus 5.05% on December 31, 2001. On a tax-adjusted basis, municipal bonds outperformed the taxable domestic bond market for the semi-annual period ended June 30, 2002, returning 7.55% (as measured by the Lehman Municipal Bond Index at a tax bracket of 38.6%) versus 3.79% for the Lehman Aggregate Index. Retail investment has reached record highs, as investors searched for a lower volatility asset class providing high after-tax returns. Institutional demand has also remained strong and is being fueled by increased profitability on the part of insurance companies, the search for stable income and asset allocation trades away from segments of the market experiencing higher volatility. Over the period, strong demand was met by significant new issuance as the first quarter of 2002 posted a 10% increase over the same period in 2001 and was the largest first quarter total on record. Through June, new 2 bond issuance remained robust, bringing total year-to-date issuance to nearly $170 billion, and is on pace to be the largest issuance year in history. The municipal yield curve remains historically steep, as the short end of the curve has outperformed Treasuries over the recent months while longer maturities performed in line with their Treasury counterparts. THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY The Trust's portfolio is actively managed to diversify exposure to various sectors, issuers, revenue sources and security types. BlackRock's investment strategy emphasizes a relative value approach, which allows the Trust to capitalize upon changing market conditions by rotating municipal sectors and coupons. Additionally, the Trust emphasizes securities whose maturity dates match the termination date of the Trust. Additionally, the Trust employs leverage to enhance its income by borrowing at short-term municipal rates and investing the proceeds in longer maturity issues that have higher yields. The degree to which the Trust can benefit from its use of leverage may affect its ability to pay high monthly income. At the end of the period, the Trust's leverage amount was approximately 36% of total assets.

See Notes to Financial Statements. 10 -------------------------------------------------------------------------------- BLACKROCK MUNICIPAL 2018 TERM TRUST NOTES TO FINANCIAL STATEMENTS (UNAUDITED) -------------------------------------------------------------------------------- NOTE 1: ORGANIZATION & ACCOUNTING POLICIES The BlackRock Municipal 2018 Term Trust (the "Trust") was organized as a Delaware business trust on September 7, 2001 as a diversified closed-end management investment company under the Investment Company Act of 1940. The Trust had no transactions until October 18, 2001 when it sold 8,028 common shares for $115,001 to BlackRock Advisors, Inc. Investment operations commenced on October 30, 2001. The Trust's investment objectives are to provide current income that is exempt from regular Federal income tax and to return $15 per common share to holders of common shares on or about December 31, 2018. The ability of issuers of debt securities held by the Trust to meet their obligations may be affected by economic developments in certain states, a specific industry or region. No assurance can be given that the Trust's investment objectives will be achieved. The following is a summary of significant accounting policies followed by the Trust. SECURITIES VALUATION: Municipal securities (including commitments to purchase such securities on a "when-issued" basis) are valued on the basis of prices provided by dealers or pricing services selected under the supervision of the Trust's Trustees. In determining the value of a particular security, pricing services may use certain information with respect to transactions in such securities, quotations from bond dealers, market transactions in comparable securities and various relationships between securities. Short-term investments may be valued at amortized cost. Any securities or other assets for which such current market quotations are not readily available are valued at fair value as determined in good faith under procedures established by and under the general supervision and responsibility of the Trust's Board of Trustees. SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are recorded on trade date. Realized and unrealized gains and losses are calculated on the identified cost basis. The Trust also records interest income on an accrual basis and amortizes premium and accretes discount to interest income on securities purchased using the interest method. SEGREGATION: In cases in which the Investment Company Act of 1940, as amended and the interpretive positions of the Securities and Exchange Commission ("SEC") require that the Trust segregate assets in connection with certain Trust investments (e.g., when issued securities, reverse repurchase agree ments or futures contracts), the Trust will, consistent with certain interpretive letters issued by the SEC, designate on its books and records cash or other liquid debt securities having a market value at least equal to the amount that would otherwise be required to be physically segregated. FEDERAL INCOME TAXES: It is the Trust's intention to elect to be treated as a regular investment company under the Internal Revenue Code and to distribute sufficient net income to shareholders. For this reason and because substantially all of the Trust's gross income consists of tax-exempt interest, no Federal income tax provision is required. DIVIDENDS AND DISTRIBUTIONS: The Trust declares and pays dividends and distributions to common shareholders monthly from net investment income, net realized short-term capital gains and other sources, if necessary. Net long-term capital gains, if any, in excess of loss carryforwards may be distributed annually. Dividends and distributions are recorded on the ex-dividend date. Dividends and distributions to preferred shareholders are accrued and determined as described in Note 4. ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. DEFERRED COMPENSATION PLAN: Under a deferred compensation plan approved by the Board of Trustees on September 24, 2001, non-interested Trustees may elect to defer receipt of all or a portion of their annual compensation. Deferred amounts earn a return as though equivalent dollar amounts had been invested in common shares of other BlackRock Trusts selected by the Trustees. This has the same economic effect for the Trustees as if the Trustees had invested the deferred amounts in such other BlackRock Trusts. The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of the Trust. The Trust may, however, elect to invest in common shares of those Trusts selected by the Trustees in order to match its deferred compensation obligations. CHANGE IN FINANCIAL STATEMENT CLASSIFICATION FOR AMPS: In accordance with the provisions of EITF D-98, "Classification and Measurement of Redeemable Securities," effective for the current period, the Trust has reclassified its Auction Market Preferred Shares ("AMPS") outside of permanent equity in the net assets section of the Statement of Assets and Liabilities. In addition, distributions to AMPS shareholders are now classified as a 11 component of net assets resulting from operations on the Statement of Operations and Changes in Net Assets and as a component of the investment operations in the Financial Highlights. Prior period amounts presented have been restated to conform to this period's presentation. This change has no impact on the net assets applicable to common shares of the Trust. NOTE 2: AGREEMENTS The Trust has an Investment Advisory Agreement with BlackRock Advisors, Inc. (the "Advisor"), a wholly owned subsidiary of BlackRock, Inc. BlackRock Financial Management, Inc., a wholly owned subsidiary of BlackRock, Inc., serves as sub-advisor to the Trust. BlackRock, Inc. is an indirect majority owned subsidiary of PNC Financial Services Group, Inc. The investment management agreement covers both investment advisory and administration services. The investment advisory fee paid to the Advisor is computed weekly and payable monthly at an annual rate of 0.40% of the Trust's average weekly managed assets. "Managed assets" means the total assets of the Trust (including any assets attributable to any preferred shares that may be outstanding) minus the sum of accrued liabilities (other than debt representing financial leverage). The total dollar amounts paid to the Advisor by the Trust under the Investment Advisory Agreement for the six months ended June 30, 2002 and the period ended December 31, 2001, were $716,331 and $179,716, respectively. Pursuant to the agreements, the Advisor provides continuous supervision of the investment portfolio, pays the compensation of officers of the Trust who are affiliated persons of the Advisor, occupancy and certain clerical and accounting costs of the Trust. The Trust bears all other costs and expenses, which include reimbursements to the Advisor for certain operational support services provided to the Trust. Pursuant to the terms of the custody agreement, the Trust receives earnings credits from its custodian when positive cash balances are maintained, which are used to offset custody fees. The earnings credits for the six months ended June 30, 2002, were approximately $19,682. NOTE 3: PORTFOLIO SECURITIES Purchases and sales of investment securities, other than short-term investments, for the six months ended June 30, 2002, aggregated $140,828,196 and $138,771,717, respectively. The Federal income tax basis of the Trust's investments at June 30, 2002 was $362,049,708, and accordingly, net unrealized appreciation was $2,880,639 (gross unrealized appreciation--$5,747,092, gross unrealized depreciation--$2,866,453). NOTE 4: CAPITAL There are an unlimited number of $.001 par value common shares of beneficial interest authorized. The Trust may classify or reclassify any unissued common shares into one or more series of preferred shares. Of the 15,908,028 common shares outstanding at June 30, 2002, the Advisor owned 8,028 shares. Transactions in common shares of beneficial interest for the period ending December 31, 2001 were as follows: Shares issued in connection with initial public offering 14,708,028 Shares issued in connection with the exercise of the underwriters' over-allotment option 1,200,000 ---------- Net increase in shares outstanding 15,908,028 ========== Offering costs of $462,000 incurred in connection with the Trust's offering of common shares have been charged to paid-in capital in excess of par of the common shares. On December 14, 2001, the Trust reclassified 5,504 common shares of beneficial interest and issued two series of Auction Market Preferred Shares ("preferred shares") Series W7--2,752 and Series R7--2,752. The preferred shares have a liquidation value of $25,000 per share plus any accumulated unpaid dividends. Underwriting discounts of $1,376,000 and offering costs of $331,743 incurred in connection with the preferred share offering have been charged to paid-in capital in excess of par of the common shares. Dividends on Series W7 and Series R7 are cumulative at a rate which is reset every 7 days based on the results of an auction. Dividend rates ranged from 1.25% to 1.60% during the six months ended June 30, 2002. The Trust 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 would be less than 200%. The preferred shares are redeemable at the option of the Trust, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends whether or not declared. The preferred shares are also subject to mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Trust as set forth in the Declaration of Trust are not satisfied. The holders of preferred shares have voting rights equal to the holders of common shares (one vote per share) and will vote together with holders of common shares as a single class. 12 However, holders of preferred shares are also entitled to elect two of the Trust's Trustees. In addition, the Investment Company Act of 1940 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 and (b) take any action requiring a vote of security holders, including, among other things, changes in the Trust's subclassification as a closed-end investment company or changes in its fundamental investment restrictions. NOTE 5: DIVIDENDS Subsequent to June 30, 2002, the Board of Trustees of the Trust declared a dividend of $0.065 per common share payable August 1, 2002 to shareholders of record on July 15, 2002. For the period July 1, 2002 to July 31, 2002, dividends declared on preferred shares totaled $151,525, in aggregate for the two outstanding preferred share series. 13 -------------------------------------------------------------------------------- BLACKROCK MUNICIPAL 2018 TERM TRUST DIVIDEND REINVESTMENT PLAN -------------------------------------------------------------------------------- Pursuant to the Trust's Dividend Reinvestment Plan (the "Plan"), common shareholders are automatically enrolled to have all distributions of dividends and capital gains reinvested by EquiServe Trust Company, N.A. (the "Plan Agent") in Trust shares pursuant to the Plan. Shareholders who elect not to participate in the Plan will receive all distributions in cash paid by check and mailed directly to the shareholders of record (or if the shares are held in street or nominee name, then to the nominee) by the Plan Agent. The Plan Agent serves as agent for the shareholders in administering the Plan. After the Trust declares a dividend or determines to make a capital gain distribution, the Plan Agent will acquire shares for the participants' accounts, by the purchase of outstanding shares on the open market ("open market purchases"), on the New York Stock Exchange or elsewhere. The Trust will not issue any new shares under the Plan. Participants in the Plan may withdraw from the Plan upon written notice to the Plan Agent and will receive certificates for whole Trust shares and a cash payment for any fraction of a Trust share. The Plan Agent's fees for handling of the reinvestment of dividends and distributions will be paid by the Trust. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open market purchases. The automatic reinvestment of dividends and distributions will not relieve participants of any Federal income tax that may be payable on such dividends or distributions. The Trust reserves the right to amend or terminate the Plan. There is no direct service charge to participants in the Plan; however, the Trust reserves the right to amend the Plan to include a service charge payable by the participants. All correspondence concerning the Plan should be directed to the Plan Agent at (800) 699-1BFM or 150 Royall Street, Canton, MA 02021. 14 -------------------------------------------------------------------------------- BLACKROCK MUNICIPAL 2018 TERM TRUST ADDITIONAL INFORMATION -------------------------------------------------------------------------------- There have been no material changes in the Trust's investment objectives or policies that have not been approved by the shareholders or to its charter or by-laws or in the principal risk factors associated with investment in the Trust.

WHO MANAGES THE TRUST? BlackRock Advisors, Inc. (the "Advisor") manages the Trust. The Advisor is a wholly owned subsidiary of BlackRock, Inc. ("BlackRock"), which is one of the largest publicly traded investment management firms in the United States with $250 billion of assets under management as of June 30, 2002. BlackRock manages assets on behalf of institutional and individual investors worldwide through a variety of equity, fixed income, liquidity and alternative investment products, including the BlackRock Funds and BlackRock Provident Institutional Funds. In addition, BlackRock provides risk management and investment system services to a growing number of institutional investors under the BlackRock Solutions name. Clients are served from the Company's headquarters in New York City, as well as offices in Boston, Edinburgh, Hong Kong, San Francisco, Tokyo and Wilmington. BlackRock is a member of The PNC Financial Services Group (NYSE: PNC), and is majority-owned by PNC and by BlackRock employees. WHAT CAN THE TRUST INVEST IN? Under normal conditions, the Trust expects to continue to manage its assets so that at least 80% of its investments are rated at least investment grade ("BBB" by Standard & Poor's or "Baa" by Moody's Investor Services) and up to 20% of its assets are rated below investment grade ("Ba/BB" or "B") or that are unrated but deemed to be of comparable quality by the Advisor. WHAT IS THE ADVISOR'S INVESTMENT STRATEGY? The Advisor will seek to meet the Trust's investment objective by managing the assets of the Trust so as to return the initial offering price of ($15 per share) on or about December 31, 2018. The Advisor will implement a strategy that will seek to closely match the maturity or call provisions of the assets of the portfolio with the future return of the initial investment at the end of 2018. At the Trust's termination, BlackRock expects that the value of the securities which have matured, combined with the value of the securities that are sold or are called, if any, will be sufficient to return the initial offering price to investors. On a continuous basis, the Trust will seek its objective by actively managing its portfolio of municipal obligations and retaining a portion of its income each year. In addition to seeking the return of the initial offering price, the Advisor also seeks to provide current income exempt from regular Federal income tax to investors. The portfolio managers will attempt to achieve this objective by investing in securities that provide competitive tax-exempt income. In addition, leverage will be used to enhance the income of the portfolio. In order to maintain competitive yields as the Trust approaches maturity and depending on market conditions, the Advisor will attempt to purchase securities with call protection or maturities as close to the Trust's maturity date as possible. Securities with call protection should provide the portfolio with some degree of protection against reinvestment risk during times of lower prevailing interest rates. Since the Trust's primary goal is to return the initial offering price at maturity, any cash that the Trust receives prior to its maturity date may be reinvested in securities with maturities which coincide with the remaining term of the Trust. It is important to note that the Trust will be managed so as to preserve the integrity of the return of the initial offering price. If market conditions, such as high interest rate volatility, force a choice between current income and risking the return of the initial offering price, it is likely that the return of the initial offering price will be emphasized. 16 HOWARE THE TRUST'S SHARES PURCHASED AND SOLD? DOES THE TRUST PAY DIVIDENDS REGULARLY? The Trust's common shares are traded on the New York Stock Exchange which provides investors with liquidity on a daily basis. Orders to buy or sell shares of the Trust must be placed through a registered broker or financial advisor. The Trust pays monthly dividends which are typically paid on the first business day of the month. For shares held in the shareholder's name, dividends may be reinvested in additional shares of the Trust through its transfer agent, EquiServe Trust Company, N.A. Investors who wish to hold shares in a brokerage account should check with their financial advisor to determine whether their brokerage firm offers dividend reinvestment services. LEVERAGE CONSIDERATIONS IN THE TRUST The Trust employs leverage primarily through the issuance of preferred shares. Leverage permits the Trust to borrow money at short-term rates and reinvest that money in longer-term assets, which typically offer higher interest rates. The difference between the cost of the borrowed funds and the income earned on the proceeds that are invested in longer-term assets is the benefit to the Trust from leverage. Leverage increases the duration (or price sensitivity of the net assets with respect to changes in interest rates) of the Trust, which can improve the performance of the Trust in a declining interest rate environment, but can cause net assets to decline faster in a rapidly rising interest rate environment. The Advisor's portfolio managers continuously monitor and regularly review the Trust's use of leverage and the Trust may reduce, or unwind, the amount of leverage employed should the Advisor consider that reduction to be in the best interests of the shareholders. SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO THE TRUST THE TRUST IS INTENDED TO BE A LONG-TERM INVESTMENT AND IS NOT A SHORT-TERM TRADING VEHICLE. INVESTMENT OBJECTIVES. Although the objectives of the Trust are to provide current income that is exempt from regular Federal income tax and to return $15 per common share to holders of common shares on or about December 31, 2018, there can be no assurance that these objectives will be achieved. DIVIDEND CONSIDERATIONS. The income and dividends paid by the Trust are likely to decline to some extent over the term of the Trust due to the anticipated shortening of the dollar-weighted average maturity of the Trust's assets. LEVERAGE. The Trust utilizes leverage through the issuance of preferred shares, which involves special risks. The Trust's net asset value and market value may be more volatile due to its use of leverage. MARKET PRICE OF SHARES. The shares of closed-end investment companies such as the Trust trade on the New York Stock Exchange (NYSE symbol: BPK) and as such are subject to supply and demand influences. As a result, shares may trade at a discount or a premium to their net asset value. MUNICIPAL OBLIGATIONS. The value of municipal debt securities generally varies inversely with changes in prevailing market interest rates. Depending on the amount of call protection that the securities in the Trust have, the Trust may be subject to certain reinvestment risks in environments of declining interest rates. HIGH YIELD RISK. The Trust may invest in high yield bonds, which involves additional risks, including credit risk. The value of high yield, lower quality bonds is affected by the creditworthiness of the issuers of the securities and by general economic and specific industry conditions. Issuers of high yield bonds are not as strong financially as those with higher credit ratings. The Trust's investment in lower grade securities will expose the Trust to greater risk than if the Trust owned only higher grade securities. ILLIQUID SECURITIES. The Trust may invest in securities that are illiquid, although under current market conditions the Trust expects to do so to only a limited extent. These securities involve special risks. ANTITAKEOVER PROVISIONS. Certain antitakeover provisions will make a change in the Trust's business or management more difficult without the approval of the Trust's Board of Trustees and may have the effect of depriving shareholders of an opportunity to sell their shares at a premium above the prevailing market price. ALTERNATIVE MINIMUM TAX (AMT). The Trust may invest in securities subject to alternative minimum tax. 17 -------------------------------------------------------------------------------- BLACKROCK MUNICIPAL 2018 TERM TRUST GLOSSARY -------------------------------------------------------------------------------- CLOSED-END FUND: Investment vehicle which initially offers a fixed number of shares and trades on a stock exchange. The Trust invests in a portfolio of securities in accordance with its stated investment objectives and policies. DISCOUNT: When a Trust's net asset value is greater than its market price, the Trust is said to be trading at a discount. DIVIDEND: Income generated by securities in a portfolio and distributed to shareholders after the deduction of expenses. This Trust declares and pays dividends to common shareholders on a monthly basis. DIVIDEND REINVESTMENT: Common shareholders may have all dividends and distributions of capital gains automatically reinvested into additional shares of the Trust. MARKET PRICE: Price per share of a security trading in the secondary market. For a closed-end Trust, this is the price at which one share of the Trust trades on the stock exchange. If you were to buy or sell shares, you would pay or receive the market price. NET ASSET VALUE (NAV): Net asset value is the total market value of all securities and other assets held by the Trust, including income accrued on its investments, minus any liabilities including accrued expenses, divided by the total number of outstanding common shares. It is the underlying value of a single common share on a given day. Net asset value for the Trust is calculated weekly and published in Barron's on Saturday and The Wall Street Journal on Monday. PREMIUM: When a Trust's market price is greater than its net asset value, the Trust is said to be trading at a premium. PREREFUNDED BONDS: These securities are collateralized by U.S. Government securities which are held in escrow and are used to pay principal and interest on the tax-exempt issue and to retire the bond in full at the date indicated, typically at a premium to par. 18 -------------------------------------------------------------------------------- BLACKROCK ADVISORS, INC.
