3 Q 1 5 U P D AT E BLACKROCK MUNICIPAL TARGET TERM TRUST (BTT) OCTOBER 2015 manages the maturity of its securities to seek a dollar weighted effective maturity approximately equal to the target term trust’s scheduled termination date. Given BTT’s scheduled termination date of on or about December 31, 2030 and its investment objective, the Trust’s portfolio is structured to avoid callability, where possible, and its holdings generally fall around the 15 year part of the yield curve, currently resulting in a higher duration than a typical perpetual municipal closed-end fund. BTT has an effective duration of 9.98 years as of 9/30/2015. The Trust also uses leverage in seeking to achieve its investment objective, although the use of leverage creates risks. As of September 30, 2015, the Trust’s portfolio was leveraged 36.64% and yields 4.71% on market price. Overview BlackRock Municipal Target Term Trust (“BTT” or the “Trust”) is a target term trust that is scheduled to terminate on or about December 31, 2030, at which time it will distribute substantially all of its net assets. The Trust’s investment objectives are to provide current income that is exempt from regular federal income tax (but which may be subject to the federal alternative minimum tax in certain circumstances) and to return $25.00 per common share (the initial public offering price per common share) to holders of common shares on or about December 31, 2030. There can be no assurance that the Trust’s investment objectives, including to return $25.00 per common share to holders of common shares on or about December 31, 2030, will be achieved or that the Trust’s investment program will be successful. BTT is organized as a closed-end investment management company and its common shares are listed and traded on the New York Stock Exchange. Financial advisors often use the 10 year U.S. Treasury (“10yr UST”) as a proxy to gauge the movement of interest rates in the market. While this method is generally accepted, we believe that using the 10yr UST as a proxy may cause misperception around investment performance for certain securities as it does not have a perfect correlation to all fixed income assets, such as municipal securities maturing in 2030 or municipal target term trusts like BTT. The investment universe for a target term trust like BTT is generally more limited than that of a typical perpetual municipal closed-end fund, as a target term trust typically 3.1 23.5 2.9 23.0 2.7 22.5 NAV ($) YIELD (%) MUNICIPAL YIELDS VS.

Tax Equivalent Yield assumes highest tax bracket (39.6%). statement that factored in international concerns like never before, stoking worry over global economic conditions. Fixed income assets rallied, with particular strength in municipal bonds, led by longer duration and high yield credits. Munis’ positive performance was further aided by the lightest September issuance in over a decade. New supply for the month came in at $18.3 billion, which was 23% below the five-year average and 31% lower than the 10-year average. Meanwhile, the demand trend seemed to point to a looming sense of investor uncertainty, with negative flows turning decidedly positive after the Fed’s decision, only to resume outflows in the final week of the month. In all, September was marked by $1.25 billion in outflows, though flows remain positive year-todate at $5.6 billion. For the year, BTT is up 1.41% on NAV and up 5.03% on market price. BTT’s market price has outpaced its’ NAV as its discount has narrowed from -13.85% at the beginning of the year to -11.08% by the end of September. Municipal closed-end funds trade at an average discount of -8.2%. Discounts remained wide and have been persistent since the “taper tantrum” in the summer of 2013 as investors remain reluctant to have exposure to long duration assets that utilize leverage for fear of future interest rate increases.

What to Keep in Mind In evaluating BTT’s share price and NAV performance, we believe that it’s important to recognize several factors, including: }The share prices of CEFs can trade independently from their NAV on a public stock exchange (e.g., NYSE) and have historically fluctuated due to, among other factors, supply and demand dynamics in the market. }CEF market price discounts to NAV often widen during times of market volatility and uncertainty. }The use of leverage within a CEF’s portfolio has the ability to enhance returns, but also poses downside risk, including the potential of increased share price and NAV volatility. }BTT is managed as a target term trust with an investment objective to return $25 per common share (the initial offering price per common share) to common shareholders on or about December 31, 2030, its scheduled termination date. There can be no assurance that this investment objective will be achieved or that the Trust’s investment program will be successful. On July 1st 2014, BTT announced a distribution reduction from $0.093750 per share to $0.080000 per share. The distribution reduction reflects the Trust’s current and projected earnings potential when considering BTT’s investment objective of returning $25 per common share (the initial public offering price per common share) to common shareholders at maturity. There can be no assurance that this investment objective will be achieved or that the Trust’s investment program will be successful. As of 8/31/2015 the trust had a 3 month average earned rate of $0.090976 per share and was paying a distribution of $0.080000. BlackRock believes that given BTT’s investment objectives, the steepness of the municipal yield curve and low short term rates, that it is prudent to use leverage for BTT. Low short term rates may provide a CEF with an attractive cost of financing. Many CEFs, including BTT, pay a spread over the SIFMA rate that floats on a weekly basis. As of September 30, 2015, the SIFMA rate stood at 2 bps. The use of leverage involves risk.

Want to know more? blackrock.com Important Information About the Trust: All information and data, including portfolio holdings and performance characteristics, is as of 9/30/15, unless otherwise noted, and is subject to change. Closed-end fund shares are not deposits or obligations of, or guaranteed by, any bank and are not insured by the FDIC or any other agency. Investing involves risk, including possible loss of principal amount invested. This is not a prospectus intended for use in the purchase or sale of Trust shares. Shares may only be purchased or sold through registered broker/dealers. For more information regarding any of BlackRock’s closed-end funds, please call BlackRock at 800-882-0052. No assurance can be given that a fund will achieve its investment objective. The market value and net asset value (NAV) of a fund’s shares will fluctuate with market conditions. Closed-end funds may trade at a premium to NAV but often trade at a discount. CEF shares are bought and sold at “market price” determined by competitive bidding on the stock exchange. Net asset value (NAV) is the value of all fund assets, less liabilities divided by the number of shares outstanding. Some BlackRock CEFs may utilize leverage to seek to enhance the yield and net asset value of their common stock, through bank borrowings, issuance of short-term debt securities or shares of preferred stock, or a combination thereof. However, these objectives cannot be achieved in all interest rate environments. While leverage may result in a higher distribution for the fund, the use of leverage involves risk, including the potential for higher volatility of the NAV, fluctuations of distributions paid by the fund and the market price of the fund’s common stock, among others. Before investing in the Trust’s common shares, you should consider the risks associated with an investment in the Trust carefully. There may be less information available on the financial condition of issuers of municipal securities than for public corporations. The market for municipal bonds may be less liquid than for taxable bonds. Municipal obligations are subject to the risk of non-payment. Many state and municipal issuers are under significant economic and financial stress. A portion of the income received from the Trust may be taxable. Some investors may be subject to Alternative Minimum Tax (AMT). Capital gains distributions, if any, are taxable. The Trust may utilize leveraging to seek to enhance the yield and net asset value of its common stock, as described in the Trust’s prospectus. These objectives will not necessarily be achieved in all interest rate environments. The use of leverage involves risk, including the potential for higher volatility and greater declines of the Trust’s net asset value, fluctuations of dividends and other distributions paid by the Trust and the market price of the Trust’s common stock, among others. The Trust’s limited term may cause it to sell securities when it otherwise would not, which could cause returns to decrease and the market price or NAV to fall. In addition, the Trust’s limited term may cause it to invest in lower yielding securities or hold cash or cash equivalents which may adversely impact performance. For more information, please refer to the Trust’s prospectus which can be found on www.sec.gov. The implementation of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) may result in a reduced availability for certain types of leverage and/or increase the costs associated with certain types of leverage. BlackRock receives credit quality ratings on underlying securities of the Trust from the three major reporting agencies - S&P, Moody’s and Fitch. The credit quality breakdown is provided by BlackRock by taking the median rating of the three agencies when all three agencies rate a security. BlackRock will use the lower of the two ratings if only two agencies rate a security, and BlackRock will use one rating if that is all that is provided. Securities that are unrated by all three agencies are reflected as such in the breakdown. Below investment-grade is represented by a rating of BB and Below. BlackRock converts all ratings to the equivalent S&P major rating category for purposes of the category shown. Ratings and portfolio credit quality may change over time. Unrated securities do not necessarily indicate low quality, unrated securities do not have an assigned credit rating. The Trust itself has not been rated by an independent rating agency.
