Shareholder Letter

Dear Shareholder,

The latter half of 2013 was a strong period for equities and other risk assets such as high yield bonds, despite the mixed tone of economic and financial news and uncertainty as to when and by how much the U.S. Federal Reserve (the “Fed”) would begin to gradually reduce (or “taper”) its asset purchase programs. Stock markets rallied in September when the Fed defied investors’ expectations with its decision to delay tapering. The momentum was soon disrupted, however, when political brinksmanship over decisions relating to the U.S. debt ceiling led to a partial government shutdown, roiling financial markets broadly until a compromise was struck in mid-October. The remainder of 2013 was generally positive for developed market stocks, while fixed income and emerging market investments struggled as Fed tapering became increasingly imminent. When the central bank ultimately announced its tapering plans in mid-December, equity investors reacted positively, as this action signaled the Fed’s perception of real improvement in the economy.

Financial markets continued to move higher in the first half of 2014 despite the gradual pull back in Fed stimulus. The year got off to a rocky start, however. A number of emerging economies showed signs of stress due to currency weakness, debt problems and uneven growth rates, while facing the broader headwind of diminishing global liquidity. Heightened risks in emerging markets combined with disappointing U.S. economic data caused equities to decline in January while bond markets found renewed strength from investors seeking relatively safer assets.

Although these headwinds persisted, equities were back on the rise in February as investors were encouraged by a one-year extension of the U.S. debt ceiling and market-friendly comments from the new Fed Chairwoman, Janet Yellen. While it was clear that U.S. economic data had softened, investors were assuaged by increasing evidence that the trend was temporary and weather-related, and continued to take on risk given expectations that growth would pick up later in the year.

In the months that followed, interest rates trended lower and bond prices climbed higher in the modest growth environment. Financial markets exhibited a remarkably low level of volatility despite rising geopolitical risks and mixed global economic data. Tensions in Russia and Ukraine and signs of decelerating growth in China caused some turbulence, but markets were resilient as investors focused on better U.S. economic data, stronger corporate earnings and increased merger-and-acquisition activity. Additionally, investors were comforted by comments from the Fed offering reassurance that no changes to short-term interest rates were on the horizon. Equity investors shifted from growth to value stocks as the strong performance of growth stocks in 2013 had pushed valuations higher in many of these sectors. More broadly, the strongest performers of 2013 struggled most in 2014, and vice versa. Emerging markets particularly benefited from this rotation into cheaper valuations. For investors in these markets, technical factors overshadowed the risks and emerging market investments surged even as a military coup in Thailand was added to the growing list of geopolitical issues in May.

Escalating violence in Iraq pushed oil prices sharply higher in June, causing a brief dip in stock markets around the world as investors were reminded of the broader risk that instability in the Middle East and North Africa poses to global oil production, although oil prices retreated later in the month. Improving U.S. data and a steady stream of mergers and acquisitions again took center stage and equities quickly resumed their upward course. Additionally, global investors were encouraged by aggressive measures taken by the European Central Bank to combat the uncomfortably low level of inflation in the eurozone, while the Fed continued to maintain a dovish stance.

All told, the riskier asset classes strongly outperformed higher quality investments for the 12-month period ended June 30. Nonetheless, most fixed income assets performed surprisingly well in the first half of 2014 even as the Fed reduced its open-market bond purchases. U.S. large cap stocks were the strongest performers in both the six- and 12-month periods, while small cap stocks lagged in the last six months given higher valuations resulting from their strong performance in 2013. Short-term interest rates remained near zero, keeping yields on money market securities close to historic lows.

At BlackRock, we believe investors need to think globally, extend their scope across a broad array of asset classes and be prepared to move freely as market conditions change over time. We encourage you to talk with your financial advisor and visit www.blackrock.com for further insight about investing in today’s world.

Sincerely,

Rob Kapito
President, BlackRock Advisors, LLC

Asset prices pushed higher over the period despite modest global growth, geopolitical risks and a shift toward tighter U.S. monetary policy.

Fund Summary as of June 30, 2014	BlackRock High Yield Municipal Fund

Investment Objective

BlackRock High Yield Municipal Fund’s (the “Fund”) investment objective is to provide shareholders with as high a level of income exempt from federal income taxes as is consistent with the investment policies of the Fund.

Effective as of January 1, 2014, the Fund’s secondary benchmark, the S&P^® Customized High Yield Municipal Bond Index, was replaced with a customized benchmark, referred to as the “Custom Index”. The Custom Index reflects the returns of the S&P^® Customized High Yield Municipal Bond Index through December 31, 2012. Beginning January 1, 2013, the Custom Index includes the returns of only those issues in the S&P^® Customized High Yield Municipal Bond Index that have maturities greater than 5 years. The investment advisor believes that this change in the performance benchmark more accurately reflects the investment strategy of the Fund.

Portfolio Management Commentary

How did the Fund perform?

•

For the 12-month period ended June 30, 2014, the Fund outperformed its primary benchmark, the S&P^® Municipal Bond Index and its new secondary benchmark, the Custom Index. The following discussion of relative performance pertains to the Custom Index.

What factors influenced performance?

•

The Fund’s long duration stance (greater sensitivity to interest rate movements) contributed positively to performance as interest rates declined during the period. (Bond prices fall as interest rates rise.) Yield curve positioning with a flattening bias and an emphasis on long-dated bonds also had a positive impact on returns. The Fund benefited from holding overweight allocations in outperforming sectors including health care, transportation, water and sewer and corporate-related debt. Additionally, exposure to non-rated bonds added to results as this segment outperformed all other rated bond categories. The Fund also benefited from maintaining an underweight exposure to Puerto Rico obligations, which lost considerable value due to deteriorating credit conditions.

•

Conversely, exposure to limited tax obligations of the city of Detroit detracted from relative performance as the value of these credits declined precipitously following the city’s bankruptcy filing in the summer of 2013. The Fund’s use of U.S. Treasury futures contracts to manage interest rate risk had a modestly negative impact on results.

Describe recent portfolio activity.

•

In the latter half of 2013, portfolio activity was dominated by sales in order to fund escalating shareholder redemptions amid the industry-wide trend of municipal bond mutual fund outflows. During these months, the Fund focused on maintaining its existing credit profile, sector weightings and leverage. However, the municipal market experienced a reversal in flows in the first half of 2014 as investors exhibited increased willingness to assume more credit risk in the search for income. The Fund invested inflows in sectors offering superior potential returns including tax-backed general obligations, utilities, education, tobacco and development districts.

Describe portfolio positioning at period end.

•

As of period end, the Fund continued to maintain a high quality bias while its sector allocations had become somewhat more diverse. The Fund continued to maintain municipal credit exposures that had been purchased in a higher rate environment. Relative to the Custom Index, the Fund was overweight in the education, health care and transportation sectors, and modestly underweight in tax-backed and tobacco credits. The Fund remained positioned to benefit from a flatter yield curve, while continuing to use U.S. Treasury futures to manage portfolio duration.

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

For Fund compliance purposes, the Fund’s sector classifications refer to any one or more of the sector sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by the investment advisor. These definitions may not apply for purposes of this report, which may combine such sector sub-classifications for reporting ease.

For financial reporting purposes, credit quality ratings shown above reflect the highest rating assigned by either Standard & Poor’s (“S&P”) or Moody’s Investors Service (“Moody’s”) if ratings differ. These rating agencies are independent, nationally recognized statistical rating organizations and are widely used. Investment grade ratings are credit ratings of BBB/Baa or higher. Below investment grade ratings are credit ratings of BB/Ba or lower. Investments designated N/R are not rated by either rating agency. Unrated investments do not necessarily indicate low credit quality. Credit quality ratings are subject to change.

The investment advisor evaluates the credit quality of unrated investments based upon certain factors including, but not limited to, credit ratings for similar investments and financial analysis of sectors and individual investments. Using this approach, the investment advisor has deemed certain of these unrated securities as investment grade quality. As of June 30, 2014, the market value of unrated securities deemed by the investment advisor to be investment grade was $7,235,537, representing 2% of the Fund’s long-term investments.

Investment Objective

BlackRock National Municipal Fund’s (the “Fund”) investment objective is to provide shareholders with as high a level of income exempt from federal income taxes as is consistent with the investment policies of the Fund.

Portfolio Management Commentary

How did the Fund perform?

•

For the 12-month period ended June 30, 2014, the Fund outperformed its benchmark, the S&P^®Municipal Bond Index.

What factors influenced performance?

•

The Fund’s overweight to California credits had a positive impact on returns relative to its benchmark as the state’s financial picture continued to improve. Exposure to higher coupon issues with defensively structured call and maturity characteristics enhanced results given strong demand for such securities as municipal bond mutual funds sought opportunities for high income with less sensitivity to rate volatility. Holdings of health care and transportation bonds were rewarding as these sectors realized significant spread tightening during the period. The Fund also benefited from its longer-maturity bond holdings as investors extended their portfolios in the search for higher-yielding investments.

•

The Fund’s cash reserves held for the purpose of providing liquidity detracted from relative results as longer-maturity investments benefited from spread tightening or interest rate movements.

Describe recent portfolio activity.

•

The Fund increased its cash equivalent reserves in the form of floating rate notes and short-term note securities were increased as the period progressed as tight credit quality spreads and low long-term investment rates warranted a more defensive stance with respect to maintaining portfolio liquidity. By the end of the 12-month period, cash reserves were relatively high compared to the industry and the Fund’s historical norm. Also during the period, the Fund reduced leverage by selling a portion of its tender option bond exposure. This was another effort to position the Fund more defensively, protecting from potential future rate volatility. Generally, portfolio activity has been aimed at realizing strong performance while seeking to mitigate future rate and credit spread volatility.

Describe portfolio positioning at period end.

•

As of period end, the Fund was positioned defensively with a bias toward high-quality securities and a high level of cash equivalent reserves. Relative to the S&P^® Municipal Bond Index, the Fund maintained a short duration posture and held overweight exposures to the health care, transportation and utilities sectors.

Fund Summary as of June 30, 2014	BlackRock Short-Term Municipal Fund

Investment Objective

BlackRock Short-Term Municipal Fund’s (the “Fund”) investment objective is to provide shareholders with as high a level of income exempt from federal income taxes as is consistent with the investment policies of the Fund.

Portfolio Management Commentary

How did the Fund perform?

•

For the 12-month period ended June 30, 2014, the Fund underperformed its primary benchmark, the S&P^® Municipal Bond Index, and its secondary benchmark, the S&P^®Limited Maturity Municipal Bond Index. The following discussion of relative performance pertains to the Fund’s secondary benchmark, the S&P^® Limited Maturity Municipal Bond Index.

What factors influenced performance?

•

The Fund’s underperformance relative to its secondary benchmark index was attributable to duration positioning (managing interest rate risk). Specifically, the Fund was underweight relative to its index in the three-year area of the yield curve, which generated strong performance for the period. The Fund’s underweight in pre-refunded issues also hindered results.

•

Conversely, sector allocation decisions had a positive impact on performance as the Fund’s holdings of corporate-backed, transportation and tax-backed issues performed well during the period. Additionally, the Fund’s overweight to State of California general obligation bonds enhanced results as the state’s financial picture continued to improve.

Describe recent portfolio activity.

•

The first half of the 12-month period was challenging for the municipal market due to heightened volatility initially driven by a rise in interest rates and subsequently exacerbated by credit events in the municipal markets. Although these trends reversed in the first half of 2014, portfolio activity throughout the 12-month period remained focused on protecting the Fund from market volatility and increasing the Fund’s credit quality bias.

Fund Summary as of June 30, 2014	BlackRock New York Municipal Bond Fund

Investment Objective

BlackRock New York Municipal Bond Fund’s (the “Fund”) investment objective is to provide shareholders with income exempt from federal income tax and New York State and New York City personal income taxes.

Effective as of January 1, 2014, the Fund’s secondary benchmark, the S&P^® New York Municipal Bond Index, was replaced with a customized benchmark, referred to as the “Custom Index.” The Custom Index reflects the returns of the S&P^® New York Municipal Bond Index through December 31, 2012. Beginning January 1, 2013, the Custom Index includes the returns of only those New York bonds in the S&P^® New York Municipal Bond Index that have maturities greater than 5 years. The investment advisor believes that this change in the performance benchmark more accurately reflects the investment strategy of the Fund.

Portfolio Management Commentary

How did the Fund perform?

•

For the 12-month period ended June 30, 2014, all share classes of the Fund outperformed its primary benchmark, the S&P^® Municipal Bond Index, while the Fund’s Institutional and Investor A1 Shares performed in-line with its new secondary benchmark, the Custom Index, and the Fund’s Investor A, Investor C and Investor C1 Shares underperformed the Custom Index. The following discussion of relative performance pertains to the Custom Index.

What factors influenced performance?

•

The Fund’s exposure to Puerto Rico government-related debt, although limited, detracted from results as credit spreads on these securities widened materially due to investor’s lack of confidence and a weak local economy. These positions were eliminated early in the period. The Fund’s use of U.S. Treasury futures contracts to manage interest rate risk had a modestly negative impact on results.

•

The largest contributors to the Fund’s performance were duration (interest rate sensitivity) and yield curve positioning. The latter half of 2013 witnessed a sharp rise in yields and steepening of the municipal yield curve, causing bond prices to fall. However, this trend reversed markedly in the first half of 2014, with municipal yields declining significantly while the yield curve flattened and more than reversed the steepening exhibited in the first half of the 12-month period. In this environment, the Fund’s longer duration and yield curve flattening overall resulted in positive performance for the period.

Describe recent portfolio activity.

•

During the first half of the 12-month period, portfolio activity was largely in response to rising interest rates and the industry-wide trend of mutual fund outflows. Given these conditions, the Fund sold lower-yielding positions with longer durations and participated in new issues to improve diversification, yield, quality and structure. In the second half of the performance period, rates fell significantly and new municipal bond issuance also declined from prior periods. As a result, overall portfolio activity was lower, but focused on selling previously out-of-favor issues that saw renewed interest as rates declined.

Describe portfolio positioning at period end.

•

Relative to the Custom Index, the Fund ended the period with a neutral-to-long duration bias and greater exposure to the long end of the yield curve.

Certain redemptions of these shares may be subject to a contingent deferred sales charge (“CDSC”) where no initial sales charge was paid at the time of purchase. Prior to October 2, 2006 for BlackRock Short-Term Municipal Fund and BlackRock New York Municipal Bond Fund, Investor A Share performance results are those of the Institutional Shares (which have no distribution or service fees) restated to reflect Investor A Share fees.

•

Investor A1 Shares (available only in BlackRock Short-Term Municipal Fund and BlackRock New York Municipal Bond Fund) are subject to a maximum initial sales charge (front-end load) of 1.00% for BlackRock Short-Term Municipal Fund and 4.00% for BlackRock New York Municipal Bond Fund; and a service fee of 0.10% per year (but no distribution fee).

•

Investor B Shares (available only in BlackRock National Municipal Fund) are subject to a maximum CDSC of 4.00%, declining to 0% after six years. In addition, these shares are subject to a distribution fee of 0.50% per year and a service fee of 0.25% per year. These shares automatically convert to Investor A Shares after approximately 10 years. (There is no initial sales charge for automatic sales conversions.) On June 10, 2013, all issued and outstanding Investor B Shares of BlackRock Short-Term Municipal Fund and BlackRock New York Municipal Bond Fund were converted into Investor A1 Shares with the same relative aggregate net asset value (“NAV”).

•

Investor C Shares are subject to a 1.00% CDSC if redeemed within one year of purchase. In addition, these shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year.

On June 10, 2013, all outstanding Investor B1 Shares of BlackRock National Municipal Fund were converted into Investor A Shares.

Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com/funds to obtain performance data current to the most recent month end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the performance tables on the previous pages assume reinvestment of all dividends and capital gain distributions, if any, at NAV on the payable date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. The Funds’ investment advisor reimbursed a portion of each Fund’s expenses. Without such reimbursement, a Fund’s performance would have been lower. The standardized 30-day yield includes the effects of any waivers and/or reimbursements. The unsubsidized 30-day yield excludes the effects of any waivers and/or reimbursements.

Disclosure of Expenses

Shareholders of these Funds may incur the following charges: (a) transactional expenses such as sales charges; and (b) operating expenses, including investment advisory fees, service and distribution fees including 12b-1 fees, and other Fund expenses. The expense examples on the previous pages (which are based on a hypothetical investment of $1,000 invested on January 1, 2014 and held through June 30, 2014) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other mutual funds.

The expense examples provide information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their Fund and share class under the headings entitled “Expenses Paid During the Period.”

The expense examples also provide information about hypothetical account values and hypothetical expenses based on a Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in these Funds and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds’ shareholder reports.

The expenses shown in the expense examples are intended to highlight shareholders’ ongoing costs only and do not reflect any transactional expenses, such as sales charges, if any. Therefore, the hypothetical examples are useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

ANNUAL REPORT

JUNE 30, 2014


The Benefits and Risks of Leveraging

The Funds may utilize leverage to seek to enhance yield and NAV. However, these objectives cannot be achieved in all interest rate environments.

Each Fund may leverage its assets through the use of proceeds received in tender option bond (“TOB”) transactions, as described in Note 3 of the Notes to Financial Statements. In a TOB transaction, a third party sponsor establishes a special purpose entity (a “TOB Trust”) into which the Fund transfers municipal bonds or other municipal securities. TOB investments generally will provide the Fund with economic benefits in periods of declining short-term interest rates, but expose the Fund to risks during periods of rising short-term interest rates. Additionally, fluctuations in the market value of municipal bonds deposited into a TOB Trust may adversely affect the Fund’s NAV per share.

In general, the concept of leveraging is based on the premise that the financing cost of leverage, which will be based on short-term interest rates, will normally be lower than the income earned by each Fund on its longer-term portfolio investments purchased with the proceeds from leverage. To the extent that the total assets of each Fund (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, the Fund’s shareholders will benefit from the incremental net income.

The interest earned on securities purchased with the proceeds from leverage is paid to Fund shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the Fund’s per share NAV. However, in order to benefit shareholders, the return on assets purchased with leverage proceeds must exceed the ongoing costs associated with the leverage. If interest and other ongoing costs of leverage exceed a Fund’s return on assets purchased with leverage proceeds, income to shareholders will be lower than if the Fund had not used leverage.

Furthermore, the value of each Fund’s portfolio investments generally varies inversely with the direction of long-term interest rates, although other factors can influence the value of portfolio investments. As a result, changes in interest rates can influence each Fund’s NAV positively or negatively in addition to the impact on Fund performance from leverage. Changes in the direction of interest rates are difficult to predict accurately, and there is no assurance that a Fund’s leveraging strategy will be successful.

The use of leverage also will generally cause greater changes in each Fund’s NAV and dividend rates than a comparable fund that does not use leverage. In a declining market, leverage is likely to cause a greater decline in the NAV of a Fund’s shares than if the Fund were not leveraged. In addition, each Fund 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 the Fund to incur losses. The use of leverage may limit a Fund’s ability to invest in certain types of securities or use certain types of hedging strategies. Each Fund will incur expenses in connection with the use of leverage, all of which are borne by Fund shareholders and may reduce income.

Derivative Financial Instruments

The Funds may invest in various derivative financial instruments, including financial futures contracts, as specified in Note 4 of the Notes to Financial Statements, which may constitute forms of economic leverage. Such derivative financial instruments are used to obtain exposure to a security, index and/or market without owning or taking physical custody of securities or to hedge market and/or interest rate risks. Derivative financial instruments involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the derivative financial instrument. The Funds’ ability to use a derivative financial instrument successfully depends on the investment advisor’s ability to predict pertinent market movements accurately, which cannot be assured. The use of derivative financial instruments may result in losses greater than if they had not been used, may require a Fund to sell or purchase portfolio investments at inopportune times or for distressed values, may limit the amount of appreciation a Fund can realize on an investment, may result in lower dividends paid to shareholders and/or may cause a Fund to hold an investment that it might otherwise sell. The Funds’ investments in these instruments are discussed in detail in the Notes to Financial Statements.

Fair Value Measurements — Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs to valuation techniques are categorized into a disclosure hierarchy consisting of three broad levels for financial statement purposes as follows:

•				Level 1 — unadjusted price quotations in active markets/exchanges for identical assets or liabilities that the Fund has the ability to access
•				Level 2 — other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)
•				Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments and derivative financial instruments)

				The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
				Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy. In accordance with the Fund’s policy, transfers between different levels of the fair value disclosure hierarchy are deemed to have occurred as of the beginning of the reporting period.

•

•				Level 1 — unadjusted price quotations in active markets/exchanges for identical assets or liabilities that the Fund has the ability to access
•				Level 2 — other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)
•				Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments and derivative financial instruments)

				The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
				Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy. In accordance with the Fund’s policy, transfers between different levels of the fair value disclosure hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of a value determined for investments and derivative financial instruments is based on the pricing transparency of the investment and derivative financial instrument and is not necessarily an indication of the risks associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and derivative financial instruments, please refer to Note 2 of the Notes to Financial Statements.

(f)				Represents the current yield as of report date.
•				Fair Value Measurements — Various inputs are used in determining the fair value of investments. These inputs to valuation techniques are categorized into a disclosure hierarchy consisting of three broad levels for financial statement purposes as follows:

•				Level 1 — unadjusted price quotations in active markets/exchanges for identical assets or liabilities that the Fund has the ability to access
•				Level 2 — other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)
•				Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments)

				The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
				Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy. In accordance with the Fund’s policy, transfers between different levels of the fair value disclosure hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of a value determined for investments is based on the pricing transparency of the investment and is not necessarily an indication of the risks associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments, please refer to Note 2 of the Notes to Financial Statements.

ANNUAL REPORT

Schedule of Investments (concluded)	BlackRock New York Municipal Bond Fund

				For Fund compliance purposes, the Fund’s sector classifications refer to any one or more of the sector sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by the investment advisor. These definitions may not apply for purposes of this report, which may combine such sector sub-classifications for reporting ease.
•				Fair Value Measurements — Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs to valuation techniques are categorized into a disclosure hierarchy consisting of three broad levels for financial statement purposes as follows:

•				Level 1 — unadjusted price quotations in active markets/exchanges for identical assets or liabilities that the Fund has the ability to access
•				Level 2 — other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs)
•				Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments and derivative financial instruments)

				The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
				Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy. In accordance with the Fund’s policy, transfers between different levels of the fair value disclosure hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of a value determined for investments and derivative financial instruments is based on the pricing transparency of the investment and derivative financial instruments and is not necessarily an indication of the risks associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments and derivative financial instruments, please refer to Note 2 of the Notes to Financial Statements.
				The following tables summarize the Fund’s investments and derivative financial instruments categorized in the disclosure hierarchy as of June 30, 2014:

ANNUAL REPORT

JUNE 30, 2014


Notes to Financial Statements

1. Organization:

BlackRock High Yield Municipal Fund (“High Yield Municipal”), BlackRock National Municipal Fund (“National Municipal”) and BlackRock Short-Term Municipal Fund (“Short-Term Municipal”) of BlackRock Municipal Bond Fund, Inc. (the “Corporation”) and BlackRock New York Municipal Bond Fund (“New York Municipal”) of BlackRock Multi-State Municipal Series Trust (the “Trust”) (collectively, the “Funds” or individually, the “Fund”) are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as diversified, open-end management investment companies. The Corporation is organized as a Maryland corporation. The Trust is organized as a Massachusetts business trust. The Board of Directors of the Corporation and the Board of Trustees of the Trust are referred to throughout this report as the “Board of Directors” or the “Board.”

Each Fund offers multiple classes of shares. BlackRock, Institutional and Service Shares are sold without a sales charge and only to certain eligible investors. Investor A and Investor A1 Shares are generally sold with an initial sales charge but may be subject to a CDSC for certain redemptions where no initial sales charge was paid at the time of purchase. Investor B, Investor C and Investor C1 Shares may be subject to a CDSC. All classes of shares have identical voting, dividend, liquidation and other rights and are subject to the same terms and conditions, except that Service, Investor A, Investor A1, Investor B, Investor C and Investor C1 Shares bear certain expenses related to the shareholder servicing of such shares, and Investor B, Investor C and Investor C1 Shares also bear certain expenses related to the distribution of such shares. Investor A1, Investor B and Investor C1 Shares are only available through exchanges and dividend reinvestments by existing shareholders and for purchase by certain employer-sponsored retirement plans. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor B and shareholders may vote on material changes to the Investor A distribution and service plan).

2. Significant Accounting Policies:

The Funds’ financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. The following is a summary of significant accounting policies followed by the Funds:

Valuation: U.S. GAAP defines fair value as the price the Funds would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Funds determine the fair value of their financial instruments at market value using independent dealers or pricing services under policies approved by the Board. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to provide oversight of the pricing function for the Funds for all financial instruments.

Municipal investments (including commitments to purchase such investments on a “when-issued” basis) are valued on the basis of prices provided by dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments and information with respect to various relationships between investments. Financial futures contracts traded on exchanges are valued at their last sale price. Investments in open-end registered investment companies are valued at NAV each business day. Short-term securities with remaining maturities of 60 days or less may be valued at amortized cost, which approximates fair value.

In the event that the application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, or its delegate, 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 Global Valuation Committee, or its delegate, seeks to determine the price that each Fund 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 Global Valuation Committee, or its delegate, deems relevant consistent with the principles of fair value measurement. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof on a quarterly basis.

Segregation and Collateralization: In cases where a Fund enters into certain investments (e.g., financial futures contracts) or certain borrowings (e.g. TOBs) that would be “senior securities” for 1940 Act purposes, the Fund may segregate or designate on its books and records cash or liquid securities having a market value at least equal to the amount of the Fund’s future obligations under such investments or borrowings. Doing so allows the investment or borrowing to be excluded from treatment as a “senior security.” Furthermore, if required by an exchange or counterparty agreement, the Fund may be required to deliver/deposit cash and/or securities to/with an exchange or broker-dealer or custodian as collateral for certain investments or obligations.

ANNUAL REPORT

JUNE 30, 2014


Notes to Financial Statements (continued)

Investment Transactions and Investment Income: For financial reporting purposes, investment transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on investment transactions are determined on the identified cost basis. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized on the accrual basis. Income, expenses and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets.

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 character and timing of dividends and distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Recent Accounting Standard: In June 2014, the Financial Accounting Standards Board issued guidance to improve the financial reporting of reverse repurchase agreements and other similar transactions. The guidance includes expanded disclosure requirements for entities that enter into reverse repurchase agreements and similar transactions accounted for as secured borrowings. The guidance is effective for financial statements with fiscal years beginning on or after December 15, 2014 and interim periods within those fiscal years. Management is evaluating the impact, if any, of this guidance on the Funds’ financial statement disclosures.

Other: Expenses directly related to a Fund or its classes are charged to that Fund or class. Other operating expenses shared by several funds are pro rated among those funds on the basis of relative net assets or other appropriate methods. Expenses directly related to the Funds and other shared expenses pro rated to the Funds are allocated daily to each class based on its relative net assets or other appropriate methods.

The Funds 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.

3. Securities and Other Investments:

Zero-Coupon Bonds: The Funds 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.

Forward Commitments and When-Issued Delayed Delivery Securities: The Funds 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 Funds 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 Funds may be required to pay more at settlement than the security is worth. In addition, the Funds are not entitled to any of the interest earned prior to settlement. When purchasing a security on a delayed delivery basis, the Funds 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 Funds’ maximum amount of loss is the unrealized appreciation of unsettled when-issued transactions, which is shown in the Schedules of Investments.

Municipal Bonds Transferred to TOBs: The Funds leverage their assets through the use of TOBs. A TOB is a special purpose entity established by a third party sponsor, into which a fund, or an agent on behalf of the fund, transfers municipal bonds into a trust (“TOB Trust”). Other funds managed by the investment advisor may also contribute municipal bonds to a TOB into which a Fund has contributed bonds. A TOB typically issues two classes of beneficial interests: short-term floating rate certificates (“TOB Trust Certificates”), which are sold to third party investors, and residual certificates (“TOB Residuals”), which are generally issued to the participating funds that contributed the municipal bonds to the TOB Trust. If multiple funds participate in the same TOB, the rights and obligations under the TOB Residual will be shared among the funds ratably in proportion to their participation.

The TOB Residuals held by a Fund include the right of a Fund (1) to cause the holders of a proportional share of the TOB Trust Certificates to tender their certificates at par plus accrued interest upon the occurrence of certain mandatory tender events defined in the TOB agreements, and (2) to transfer, subject to a specified number of days prior notice, a corresponding share of the municipal bonds from the TOB to a Fund. The TOB may also be collapsed without the consent of a Fund, as the TOB Residual holder, upon the occurrence of certain termination 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 renewal of the liquidity support agreement, a substantial decline in market value of the municipal bond and a judgment or ruling that interest on the municipal bond is subject to federal income taxation. Upon the occurrence of a termination event, the TOB would generally be liquidated in full with the proceeds typically applied first to any accrued fees owed to the trustee, remarketing agent and liquidity provider, and then to the holders of the TOB Trust Certificates up to par plus accrued interest owed on the TOB Trust Certificates, with the balance paid out to the TOB Residual holder. During the year ended June 30, 2014, no TOBs in which the Funds participated were terminated without the consent of the Funds.

ANNUAL REPORT

JUNE 30, 2014


Notes to Financial Statements (continued)

The cash received by the TOB from the sale of the TOB Trust Certificates, less transaction expenses, is paid to a Fund. The Fund typically invests the cash received in additional municipal bonds. Each Fund’s transfer of the municipal bonds to a TOB Trust is accounted for as a secured borrowing; therefore the municipal bonds deposited into a TOB are presented in the Funds’ Schedules of Investments and the TOB Trust Certificates are shown in other liabilities in the Statements of Assets and Liabilities. The carrying amount of the Fund’s payable to the holder of the TOB Trust Certificates, as reported in Statements of Assets and Liabilities as TOB Trust Certificates, approximates its fair value.

The Funds may invest in TOBs on either a non-recourse or recourse basis. TOB Trusts are typically supported by a liquidity facility provided by a bank or other financial institution (the “Liquidity Provider”) that allows the holders of the TOB Trust Certificates to tender their certificates in exchange for payment from the Liquidity Provider of par plus accrued interest on any business day prior to the occurrence of the termination events described above. When a Fund invests in TOBs on a non-recourse basis, and the Liquidity Provider is required to make a payment under the liquidity facility due to a termination event, the Liquidity Provider will typically liquidate all or a portion of the municipal securities held in the TOB Trust and then fund, on a net basis, the balance, if any, of the amount owed under the liquidity facility over the liquidation proceeds (the “Liquidation Shortfall”). If a Fund invests in a TOB on a recourse basis, the Fund will typically enter into a reimbursement agreement with the Liquidity Provider where the Fund is required to repay the Liquidity Provider the amount of any Liquidation Shortfall. As a result, a Fund investing in a recourse TOB will bear the risk of loss with respect to any Liquidation Shortfall. If multiple funds participate in any such TOB, these losses will be shared ratably, including the maximum potential amounts owed by the Funds at June 30, 2014, in proportion to their participation. The recourse TOB Trusts are identified in the Schedules of Investments including the maximum potential amounts owed by each Fund at June 30, 2014.

Interest income, including amortization and accretion of premiums and discounts, from the underlying municipal bonds is recorded by the Funds 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 TOB Trust Certificates have interest rates that generally reset weekly and their holders have the option to tender such certificates to the TOB for redemption at par at each reset date. At June 30, 2014, the aggregate value of the underlying municipal bonds transferred to TOBs, the related liability for TOB Trust Certificates and the range of interest rates on the liability for TOB Trust Certificates were as follows:

	Underlying Municipal Bonds Transferred to TOBs		Liability for Trust Certificates		Range of Interest Rates

New York Municipal	$	34,064,981	$	18,710,577	0.06% - 0.11%

For the year ended June 30, 2014, the Funds’ average TOB trust certificates outstanding and the daily weighted average interest rate, including fees, were as follows:

	Average TOB Trust Certificates Outstanding		Daily Weighted Average Interest Rate
High Yield Municipal	$	35,928,616	0.67%
National Municipal	$	421,772,115	0.60%
New York Municipal	$	19,095,756	0.63%

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

4. Derivative Financial Instruments:

The Funds engage in various portfolio investment strategies using derivative contracts both to increase the returns of the Funds and/or to economically hedge their exposure to certain risks such as interest rate risk. These contracts may be transacted on an exchange or over-the-counter (“OTC”).

Financial Futures Contracts: The Funds purchase and/or sell financial futures contracts and options on financial futures contracts to gain exposure to, or economically hedge against, changes in interest rates (interest rate risk). Financial futures contracts are agreements between the Funds and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the particular contract, financial futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date.

Upon entering into a financial futures contract, the Funds are required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on a contract’s size and risk profile. The initial margin deposit must then be maintained at an established level over the life of the contract. Securities deposited as initial margin are designated on the Schedules of Investments and cash deposited, if any, is recorded on the Statements of Assets and Liabilities as cash pledged for financial futures contracts. Pursuant to the contract, the Funds agree to receive from or pay to the

ANNUAL REPORT

Notes to Financial Statements (continued)

broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin. Variation margin is recorded by the Funds as unrealized appreciation or depreciation and, if applicable, as a receivable or payable for variation margin in the Statements of Assets and Liabilities.

When the contract is closed, the Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The use of financial futures contracts involves the risk of an imperfect correlation in the movements in the price of financial futures contracts, interest rates and the underlying assets.

For the year ended June 30, 2014, the average quarterly balances of outstanding derivative financial instruments were as follows:

Average notional value of contracts sold	$	33,538,387	$	70,200,195	$	15,650,027

Counterparty Credit Risk: A derivative contract may suffer a mark-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract.

With exchange-traded futures, there is less counterparty credit risk to the Funds since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, a Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default (including the bankruptcy or insolvency) of the clearing broker or clearinghouse. Additionally, credit risk exists in exchange traded futures with respect to initial and variation margin that is held in a clearing broker’s customer accounts. While clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients, typically the shortfall would be allocated on a pro rata basis across all the clearing broker’s customers, potentially resulting in losses to the Funds.

5. Investment Advisory Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. is the largest stockholder and an affiliate, for 1940 Act purposes, of BlackRock, Inc. (“BlackRock”).

The Corporation and the Trust, on behalf of the Funds, entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Manager”), the Funds’ investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services. The Manager is responsible for the management of each Fund’s portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of each Fund. For such services, each Fund pays the Manager a monthly fee based on the following annual rates:

High Yield Municipal:

Portion of Average Daily Net Assets	Investment Advisory Fee
First $250 Million		0.550	%
$250 — $500 Million		0.525	%
Greater than $500 Million		0.500	%

National Municipal and Short-Term Municipal:

	Rate of Advisory Fee
Aggregate of Average Daily Net Assets of the Two Combined Funds¹	National Municipal			Short-Term Municipal
First $250 Million		0.500	%		0.400	%
$250 Million — $400 Million		0.475	%		0.375	%
$400 Million — $550 Million		0.475	%		0.350	%
Greater than $550 Million		0.475	%		0.325	%

The portion of the assets of a Fund to which the rate of each breakpoint level applies will be determined on a “uniform percentage” basis. The uniform percentage applicable to a breakpoint level is determined by dividing the amount of the aggregate average daily net assets of the two combined Funds that falls within that breakpoint level by the aggregate average daily net assets of the two combined Funds. The amount of the fee for a Fund at each breakpoint level is determined by multiplying the average daily net assets of that Fund by the uniform percentage applicable to that breakpoint level and multiplying the product by the advisory fee rate.

New York Municipal:

				Investment Advisory Fee
Portion of Average Daily Net Assets					0.550	%

The Manager voluntarily agreed to waive a portion of its fees payable by New York Municipal, which is included in fees waived by Manager in the Statements of Operations, so that such fee is reduced for average daily net assets of the Fund as follows:

Portion of Average Daily Net Assets				Rate
First $500 Million				0.550%
$500 — $1 Billion				0.525%
Greater than $1 Billion				0.500%

The Manager voluntarily agreed to waive its investment advisory fees by the amount of investment advisory fees each Fund pays to the Manager indirectly through its investment in affiliated money market funds. However, the Manager does not waive its investment advisory fees by the amount of investment advisory fees paid in connection with each Fund’s investment in other affiliated investment companies, if any. These amounts are included in fees waived by Manager in the Statements of Operations.

For the year ended June 30, 2014, the amounts waived were as follows:

High Yield Municipal	$	6,987
National Municipal	$	43,876
Short-Term Municipal	$	6,876
New York Municipal	$	3,343

ANNUAL REPORT

Notes to Financial Statements (continued)

For National Municipal, Short-Term Municipal and New York Municipal, the Manager contractually or voluntarily agreed to waive and/or reimburse fees and expenses, excluding interest expense, dividend expense, acquired fund fees and expenses and certain other fund expenses, which constitute extraordinary expenses not incurred in the ordinary course of the Funds’ business, in order to limit expenses. The expense limitations as a percentage of net assets are as follows:

	National Municipal			Short-Term Municipal			New York Municipal
	Contractual¹			Voluntary²			Contractual^1,3
BlackRock		0.46	%		—			—
Institutional		—			0.40	%		0.65	%

Investor B		1.23	%		—			—
Investor C		1.47	%		1.55	%		1.64	%
Investor C1		1.28	%		—			—

The Manager has agreed not to reduce or discontinue this contractual waiver and/or reimbursement prior to November 1, 2015 unless approved by the Board, including a majority of the Independent Directors.

These voluntary waivers and/or reimbursements may be reduced or discontinued at any time without notice.

Effective starting June 1, 2014.

As a result, for National Municipal, Short-Term Municipal and New York Municipal, the Manager waived or reimbursed the following amounts which are shown as transfer agent fees waived and/or reimbursed — class specific in the Statements of Operations:

	National Municipal		Short-Term Municipal		New York Municipal
BlackRock	$	146,828		—		—
Institutional		—	$	635,310	$	2,003

	Fees Waived by Manager
National Municipal	$	2,281,904
Short-Term Municipal	$	70
New York Municipal	$	5,627

If during the Fund’s fiscal year the operating expenses of a share class, that at any time during the prior two fiscal years received a waiver or reimbursement from the Manager, are less than the expense limit for that share class, the Manager is entitled to be reimbursed by such share class up to the lesser of (a) the amount of fees waived or expenses reimbursed during those prior two fiscal years under the agreement and (b) the amount by which the expense limit for that share class exceeds the operating expenses of the share class for the current fiscal year, provided that: (1) the Fund, of which the share class is a part, has more than $50 million in assets for the fiscal year and (2) the Manager or an affiliate continues to serve as the Fund’s investment advisor or administrator. In the event the expense limit for a share class is changed subsequent to a fiscal year in which the Manager becomes entitled to reimbursement for fees waived or reimbursed, the amount available to reimburse the Manager shall be calculated by reference to the expense limit for that share class in effect at the time the Manager became entitled to receive such reimbursement, rather than the subsequently changed expense limit for that share class.

For the year ended June 30, 2014, the Manager did not recoup any of New York Municipal’s fund level or class specific waivers and/or reimbursements.

7. Income Tax Information:

It is the Funds’ 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 their taxable income to their shareholders. Therefore, no federal income tax provision is required.

Each Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Funds’ U.S. federal tax returns remains open for each of the four years ended June 30, 2014. The statutes of limitations on each Fund’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Management has analyzed tax laws and regulations and their application to each Fund’s facts and circumstances and does not believe there are any uncertain tax positions that require recognition of a tax liability.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. As of June 30, 2014, the following permanent differences attributable to amortization methods on fixed income securities and the expiration of capital loss carryforwards were reclassified to the following accounts:

	High Yield Municipal			National Municipal			Short-Term Municipal			New York Municipal
Paid-in capital		—			—		$	(1,707,147	)		—
Undistributed net investment income	$	(67,551	)	$	(729,811	)	$	(1,367	)	$	(2,043	)
Accumulated net realized loss	$	67,551		$	729,811		$	1,708,514		$	2,043

The tax character of distributions paid was as follows:

		High Yield Municipal		National Municipal		Short-Term Municipal		New York Municipal
Tax-exempt income¹	6/30/14	$	15,937,366	$	170,615,236	$	3,661,275	$	9,481,769
	6/30/13		15,928,393		181,182,652		5,312,978		10,831,600
Ordinary income²	6/30/14		158,507		81,120		321		14,066
	6/30/13		30,506		69,669		—		14,320
Total	6/30/14	$	16,095,873	$	170,696,356	$	3,661,596	$	9,495,835
	6/30/13	$	15,958,899	$	181,252,321	$	5,312,978	$	10,845,920

The Funds designate these amounts paid during the fiscal year ended June 30, 2014, as exempt-interest dividends.

Ordinary income consists primarily of taxable income recognized from market discount. Additionally, all ordinary income distributions are comprised of interest related dividends for non-U.S. residents and are eligible for exemption from U.S. withholding tax for nonresident aliens and foreign corporations.

As of June 30, 2014, the tax components of accumulated net earnings (losses) were as follows:

	High Yield Municipal			National Municipal			Short-Term Municipal			New York Municipal
Undistributed tax-exempt income	$	116,736		$	2,036,143		$	490,230		$	242,106
Undistributed ordinary income		61,264			32,745			—			10,683
Capital loss carryforwards		(14,827,841	)		(112,611,319	)		(3,310,155	)		(8,036,056	)
Net unrealized gains³		18,627,314			364,604,883			4,390,282			15,664,197
Qualified late-year losses⁴		(5,536,781	)		(14,548,329	)		—			(2,600,153	)
Total	$	(1,559,308	)	$	239,514,123		$	1,570,357		$	5,280,777

The difference between book-basis and tax-basis net unrealized gains was attributable primarily to the tax deferral of losses on wash sales, amortization methods for premiums and discounts on fixed income securities, the realization for tax purposes of unrealized gains/losses on certain futures contracts, the accrual of income on securities in default and the treatment of residual interests in tender option bond trusts.

⁴

The Funds have elected to defer certain qualified late-year losses and recognize such losses in the year ending June 30, 2015.

8. Bank Borrowings:

The Corporation and the Trust, on behalf of the Funds, along with certain other funds managed by the Manager and its affiliates (“Participating Funds”), are parties to a 364-day, $1.1 billion credit agreement with a group of lenders, under which the Funds may borrow to fund shareholder redemptions. The agreement expires in April 2015. Excluding commitments designated for a certain individual fund, other Participating Funds, including the Funds, can borrow up to an aggregate commitment amount of $650 million, subject to asset coverage and other limitations as specified in the agreement. The credit agreement has the following terms: a fee of 0.06% per annum on unused commitment amounts and interest at a rate equal to the higher of (a) the one-month LIBOR plus 0.80% per annum or (b) the Fed Funds rate plus 0.80% per annum on amounts borrowed. Participating Funds paid administration and arrangement fees which, along with commitment fees, were allocated among such funds based upon portions of the aggregate commitment available to them and relative net assets of Participating Funds. The Funds did not borrow under the credit agreement during the year ended June 30, 2014.

9. Concentration, Market and Credit Risk:

New York Municipal invests a substantial amount of its assets in issuers located in a single state or limited number of states. Please see the Schedules of Investments for concentrations in specific states or U.S. territories.

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

In the normal course of business, the Fund invests 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 Fund may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Fund; 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 Fund may be exposed to counterparty credit risk, or the risk that an entity with which the Fund has unsettled or open transactions may fail to or be unable to perform on its commitments. The Fund manages counterparty credit risk by entering into transactions only with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Funds to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Funds’ exposure to market, issuer and counterparty credit risks with respect to these financial assets is generally approximated by their value recorded in the Statements of Assets and Liabilities, less any collateral held by the Funds.

The Funds invest a significant portion of its assets in fixed-income securities and/or uses derivatives tied to the fixed income markets. See the Schedule of Investments for these securities and/or derivatives. Changes in market interest rates or economic conditions, including the Federal Reserve’s decision in December 2013 to taper its quantitative easing policy, may affect the value and/or liquidity of such investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates.

Notes to Financial Statements (continued)

As of June 30, 2014, High Yield Municipal invested a significant portion of its assets in securities in the health sector. National Municipal invested a significant portion of its assets in securities in the utilities, transportation and health sectors. Short-Term Municipal invested a significant portion of its assets in securities in the state and county/city/special district/school district sectors. New York Municipal invested a significant portion of its assets in securities in the county/city/special district/school district sector. Changes in economic conditions affecting the county/city/special district/school district, heath, state, transportation and utilities sectors would have a greater impact on the Funds and could affect the value, income and/or liquidity of positions in such securities.

The Funds may hold a significant amount of bonds subject to calls by the issuers at defined dates and prices. When bonds are called by issuers and the Funds reinvest the proceeds received, such investments may be in securities with lower yields than the bonds originally held, and correspondingly, could adversely impact the yield and total return performance of a fund.

On December 10, 2013, regulators published final rules implementing section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Volcker Rule”), which prohibit banking entities from engaging in proprietary trading of certain instruments and limit such entities’ investments in, and relationships with, “covered funds,” as defined in the rules. Banking entities subject to the Volcker Rule are required to fully comply by July 21, 2015. The Volcker Rule may preclude banking entities and their affiliates from (i) sponsoring TOB trust programs (as such programs are presently structured) and (ii) continuing relationships with or services for existing TOB trust programs. As a result, TOB trusts may need to be restructured or unwound. There can be no assurances that TOB trusts can be restructured, that new sponsors of TOB trusts will develop, or that alternative forms of leverage will be available to the Funds. Any alternative forms of leverage may be more or less advantageous to the Funds than existing TOB leverage.

TOB transactions constitute an important component of the municipal bond market. Accordingly, implementation of the Volcker Rule may adversely impact the municipal market, including through reduced demand for and liquidity of municipal bonds and increased financing costs for municipal issuers. Any such developments could adversely affect the Funds. The ultimate impact of these rules on the TOB market and the overall municipal market is not yet certain.

Report of Independent Registered Public Accounting Firm

To the Shareholders of BlackRock High Yield Municipal Fund, BlackRock National Municipal Fund, BlackRock Short-Term Municipal Fund and BlackRock New York Municipal Bond Fund and Board of Directors of BlackRock Municipal Bond Fund, Inc. and Board of Trustees of BlackRock Multi-State Municipal Series Trust:

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of BlackRock High Yield Municipal Fund, BlackRock National Municipal Fund and BlackRock Short-Term Municipal Fund of BlackRock Municipal Bond Fund, Inc., and BlackRock New York Municipal Bond Fund of BlackRock Multi-State Municipal Series Trust (collectively the “Funds”), as of June 30, 2014, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented. These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of June 30, 2014, by correspondence with the custodians and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial positions of BlackRock High Yield Municipal Fund, BlackRock National Municipal Fund and BlackRock Short-Term Municipal Fund of BlackRock Municipal Bond Fund, Inc., and BlackRock New York Municipal Bond Fund of BlackRock Multi-State Municipal Series Trust, as of June 30, 2014, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented in conformity with accounting principles generally accepted in the United States of America.

Disclosure of Investment Advisory Agreements

The Board of Directors of BlackRock Municipal Bond Fund (the “Corporation”) and the Board of Trustees of BlackRock Multi-State Municipal Series Trust (the “Trust”), (collectively, the “Board,” and the members of which are referred to as “Board Members”) met in person on April 8, 2014 (the “April Meeting”) and May 13-14, 2014 (the “May Meeting”) to consider the approval of the investment advisory agreements (collectively, the “Advisory Agreements”), between the Corporation, on behalf of the BlackRock High Yield Municipal Fund (the “High Yield Fund”), BlackRock National Municipal Fund (the “National Fund”) and BlackRock Short-Term Municipal Fund (the “Short-Term Fund”), each a series of Corporation, and BlackRock Advisors, LLC (the “Manager” or “BlackRock”), and between the Trust, on behalf of the BlackRock New York Municipal Bond Fund (the “New York Fund,” along with the High Yield Fund, National Fund and Short-Term Fund, each a “Fund,” and collectively, the “Funds”), a series of Trust, and BlackRock, each Fund’s investment advisor. At the May Meeting, it was noted that the sub-advisory agreements between the Manager and BlackRock Investment Management, LLC, with respect to each Fund, would expire effective July 1, 2014. It was also noted that the non-renewal of the sub-advisory agreements would not result in any change in the nature or quality of services provided to the Funds, or in the portfolio management team that serves each Fund.

Activities and Composition of the Board

The Board consists of thirteen individuals, ten of whom are not “interested persons” of the Corporation or the Trust as defined in the Investment Company Act of 1940, as amended (the “1940 Act”) (the “Independent Board Members”). The Board Members are responsible for the oversight of the operations of the Funds 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 Board is an Independent Board Member. The Board has 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 chaired by an Independent Board Member and composed of Independent Board Members (except for the Performance Oversight Committee and the Executive Committee, each of which also has one interested Board Member).

The Agreements

Pursuant to the 1940 Act, the Board is required to consider the continuation of the Agreements on an annual basis. The Board has four quarterly meetings per year, each extending over two days, and a fifth one-day meeting to consider specific information surrounding the consideration of renewing the Agreements. In connection with this process, the Board assessed, among other things, the nature, scope and quality of the services provided to each Fund by BlackRock, its personnel and its affiliates, including (as applicable) investment management; administrative and shareholder services; oversight of fund service providers; marketing services; risk oversight; compliance and assistance in meeting applicable legal and regulatory requirements.

The Board, acting directly and through its committees, considers at each of its meetings, and from time to time as appropriate, factors that are relevant to its annual consideration of the renewal of the Agreements, including the services and support provided by BlackRock to each Fund and its shareholders. Among the matters the Board considered were: (a) investment performance for one-year, three-year, five-year and/or since inception periods, as applicable, against peer funds, and applicable benchmarks, if any, as well as senior management’s and portfolio managers’ analysis of the reasons for any over-performance or underperformance against its peers and/or benchmark, as applicable; (b) fees, including advisory, administration, if applicable, and other amounts paid to BlackRock and its affiliates by each Fund for services, such as marketing and distribution, call center and fund accounting; (c) Fund operating expenses and how BlackRock allocates expenses to each Fund; (d) the resources devoted to, risk oversight of, and compliance reports relating to, implementation of each Fund’s investment objective, policies and restrictions, and meeting new regulatory requirements; (e) each Fund’s compliance with its Code of Ethics and other 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 and risk and compliance oversight mechanisms; (h) BlackRock’s implementation of the proxy voting policies approved by the Board; (i) execution quality of portfolio transactions; (j) BlackRock’s implementation of each Fund’s valuation and liquidity procedures; (k) an analysis of management fees for products with similar investment objectives across the open-end fund, exchange-traded fund (“ETF”), closed-end fund and institutional account product channels, as applicable, and the similarities and differences between the services provided to these products as compared to the Fund; (l) BlackRock’s compensation methodology for its investment professionals and the incentives it creates; and (m) periodic updates on BlackRock’s business.

The Board has engaged in an ongoing strategic review with BlackRock of opportunities to consolidate funds and of BlackRock’s commitment to investment performance. BlackRock also furnished information to the Board in response to specific questions. These questions covered issues such as: BlackRock’s profitability; investment performance; subadvisory and advisory relationships with other clients (including mutual funds sponsored by third parties); the viability of specific funds; manager capacity and the potential for closing certain funds to new investments; portfolio managers’ investments in funds they manage; supplemental service agreements with third party distribution partners; and management fee levels and breakpoints. The Board further discussed with BlackRock: BlackRock’s management structure; portfolio turnover, execution quality and use of soft dollars; BlackRock’s portfolio manager compensation and performance accountability; marketing support for the funds; services provided to the funds by BlackRock affiliates; and BlackRock’s oversight of relationships with third party service providers.

Board Considerations in Approving the Agreements

The Approval Process: Prior to the April Meeting, the Board requested and received materials specifically relating to the Agreements. The Board is continuously engaged in a process with its independent legal counsel and BlackRock to review the nature and scope of the information provided to better assist its deliberations. The materials provided in connection with the April Meeting included (a) information independently compiled

(“Lipper”) on Fund fees and expenses as compared with a peer group of funds as determined by Lipper (“Expense Peers”) and the investment performance of each Fund as compared with a peer group of funds as determined by Lipper¹ and, for the National Fund, a customized peer group selected by BlackRock; (b) information on the profits realized by BlackRock and its affiliates pursuant to the Agreements and a discussion of fall-out benefits to BlackRock and its affiliates; (c) a general analysis provided by BlackRock concerning investment management fees charged to other clients, such as institutional clients, ETFs and closed-end funds, under similar investment mandates, as well as the performance of such other clients, as applicable; (d) review of non-management fees; (e) the existence, impact and sharing of potential economies of scale; (f) a summary of aggregate amounts paid by each Fund to BlackRock; (g) sales and redemption data regarding each Fund’s shares; and (h) if applicable, a comparison of management fees to similar BlackRock open-end funds, as classified by Lipper.

At the April Meeting, the Board reviewed materials relating to its consideration of the Agreements. As a result of the discussions that occurred during the April Meeting, and as a culmination of the Board’s year-long deliberative process, the Board presented BlackRock with questions and requests for additional information. BlackRock responded to these requests with additional written information in advance of the May Meeting.

At the May Meeting, the Board, including the Independent Board Members, approved the continuation of the Advisory Agreements between the Manager and the Corporation, on behalf of the High Yield Fund, the National Fund and the Short-Term Fund, and the Trust, on behalf of the New York Fund, each for a one-year term ending June 30, 2015. In approving the continuation of the Agreements, the Board 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) each Fund’s costs to investors compared to the costs of Expense Peers and performance compared to the relevant performance comparison as previously discussed; (e) economies of scale; (f) fall-out benefits to BlackRock and its affiliates as a result of its relationship with each Fund; and (g) other factors deemed relevant by the Board Members.

The Board also considered other matters it deemed important to the approval process, such as payments made to BlackRock or its affiliates relating to the distribution of Fund shares and securities lending, services related to the valuation and pricing of Fund portfolio holdings, direct and indirect benefits to BlackRock and its affiliates from their relationship with each Fund and advice from independent legal counsel with respect to the review process and materials submitted for the Board’s review. The Board noted the willingness of BlackRock personnel to engage in open, candid discussions with the Board. The Board did not identify any particular information as determinative, 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 Board, 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 Board compared Fund performance to the performance of a comparable group of mutual funds and/or the performance of a relevant benchmark, as applicable. The Board met with BlackRock’s senior management personnel responsible for investment activities, including the senior investment officers. The Board 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 Board considered, among other factors, with respect to BlackRock: the number, education and experience of investment personnel generally and each Fund’s portfolio management team; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use of technology; commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board engaged in a review 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 and create performance incentives.

In addition to advisory services, the Board considered the quality of the administrative and other non-investment advisory services provided to each Fund. BlackRock and its affiliates provide each Fund with certain administrative, shareholder 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 particular, BlackRock and its affiliates provide each Fund with the following administrative services including, among others: (i) preparing disclosure documents, such as the prospectus, the summary prospectus (as applicable), the statement of additional information and periodic shareholder reports; (ii) oversight of daily accounting and pricing; (iii) overseeing and coordinating the activities of other service providers; (iv) organizing Board meetings and preparing the materials for such Board meetings; (v) providing legal and compliance support; (vi) furnishing analytical and other support to assist the Board in its consideration of strategic issues such as the merger or consolidation of certain open-end funds; and (vii) performing other administrative functions necessary for the operation of each Fund, such as tax reporting, fulfilling regulatory filing requirements and call center services. The Board reviewed the structure and duties of BlackRock’s fund administration, shareholder services, legal and compliance departments and considered BlackRock’s policies and procedures for assuring compliance with applicable laws and regulations.

B. The Investment Performance of each Fund and BlackRock: The Board, including the Independent Board Members, also reviewed and considered the performance history of each Fund. In preparation for the April Meeting, the Board worked with its independent legal counsel, BlackRock and Lipper to develop a template for, and was provided with, reports independently prepared by Lipper, which included a comprehensive analysis of each Fund’s performance. The Board 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 its review, the Board received and reviewed information regarding the investment performance of each Fund as compared to other funds in its

Funds are ranked by Lipper in quartiles, ranging from first to fourth, where first is the most desirable quartile position and fourth is the least desirable.

applicable Lipper category and, for the National Fund, a customized peer group selected by BlackRock. The Board was provided with a description of the methodology used by Lipper to select peer funds and periodically meets with Lipper representatives to review its methodology. The Board and its Performance Oversight Committee regularly review, and meet with Fund management to discuss, the performance of each Fund throughout the year.

The Board noted that for the one-, three- and five-year periods reported, the High Yield Fund ranked in the fourth, second and second quartiles, respectively, against its Lipper Performance Universe Composite. BlackRock believes that the Lipper Performance Universe Composite is an appropriate performance metric for the High Yield Fund in that it measures a blend of total return and yield. The Board and BlackRock reviewed and discussed the reasons for the High Yield Fund’s underperformance during the one-year period and noted that they will monitor the Fund’s performance.

The Board noted that for the one-, three- and five-year periods reported, the National Fund ranked in the first, second and first quartiles, respectively, against its Customized Lipper Peer Group Composite. BlackRock believes that the Customized Lipper Peer Group Composite is an appropriate performance metric for the National Fund in that it measures a blend of total return and yield.

The Board noted that for the one-, three- and five-year periods reported, the Short-Term Fund ranked in the third, fourth and fourth quartiles, respectively, against its Lipper Performance Universe. The Board and BlackRock reviewed and discussed the reasons for the Short-Term Fund’s underperformance during these periods. The Board was informed that, among other things, the Short-Term Fund’s performance can generally be tied to the performance of the yield curve in any given period since the Short-Term Fund is restricted to holding securities with a maximum maturity of four years. Many of the funds in the Lipper Performance Universe do not have restrictions with regard to final maturity of permissible securities as long as the funds maintain a shorter portfolio duration.

The Board and BlackRock also discussed BlackRock’s strategy for improving the Short-Term Fund’s performance and BlackRock’s commitment to providing the resources necessary to assist the Short-Term Fund’s portfolio managers in seeking to improve the Short-Term Fund’s performance.

The Board noted that for the one-, three- and five-year periods reported, the New York Fund ranked in the third, second and second quartiles, respectively, against its Lipper Performance Universe Composite. BlackRock believes that the Lipper Performance Universe Composite is an appropriate performance metric for the New York Fund in that it measures a blend of total return and yield. The Board and BlackRock reviewed and discussed the reasons for the New York Fund’s underperformance during the one-year period and noted that they will monitor the New York Fund’s performance.

C. Consideration of the Advisory/Management Fees and the Cost of the Services and Profits to be Realized by BlackRock and its Affiliates from their Relationship with each Fund: The Board, including the Independent Board Members, reviewed each Fund’s contractual management fee rate compared with the other funds in its Lipper category. The contractual management fee rate represents a combination of the advisory fee and any administrative fees, before taking into account any reimbursements or fee waivers. The Board also compared each Fund’s total expense ratio, as well as its actual management fee rate, to those of other funds in its Lipper category. The total expense ratio represents a fund’s total net operating expenses, including any 12b-1 or non 12b-1 service fees. The total expense ratio gives effect to any expense reimbursements or fee waivers that benefit a fund, and the actual management fee rate gives effect to any management fee reimbursements or waivers that benefit a fund. The Board considered the services provided and the fees charged by BlackRock and its affiliates to other types of clients with similar investment mandates, as applicable, including institutional accounts.

The Board received and reviewed statements relating to BlackRock’s financial condition. The Board was also provided with a profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to each Fund. The Board reviewed BlackRock’s profitability with respect to each Fund and other funds the Board currently oversees for the year ended December 31, 2013 compared to available aggregate profitability data provided for the two prior years. The Board reviewed BlackRock’s profitability with respect to certain other fund complexes managed by the Manager and/or its affiliates. The Board 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 Board 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, precision of expense allocations and business mix. As a result, calculating and comparing profitability at individual fund levels is difficult.

The Board noted that, in general, individual fund or product line profitability of other advisors is not publicly available. The Board reviewed BlackRock’s overall operating margin, in general, compared to that of certain other publicly-traded asset management firms. The Board considered the differences between BlackRock and these other firms, including the contribution of technology at BlackRock, BlackRock’s expense management, and the relative product mix.

In addition, the Board 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 its analysis, the Board reviewed BlackRock’s methodology in allocating its costs to the management of each Fund. The Board 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 Board. The Board further considered factors including but not limited to BlackRock’s commitment of time, assumption of risk and liability profile in servicing each Fund in contrast to what is required of BlackRock with respect to other products with similar investment objectives across the open-end fund, ETF, closed-end fund and institutional account product channels, as applicable.

The Board noted that the High Yield Fund’s contractual management fee rate ranked in the second quartile, and that the actual management fee rate and total expense ratio each ranked in the fourth quartile, relative to the High Yield Fund’s Expense Peers. The Board determined that the High Yield Fund’s total expense ratio was appropriate in light of the median total expense ratio paid by the High Yield Fund’s Expense Peers. The Board

also noted that the High Yield Fund has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the size of the Fund increases above certain contractually specified levels.

The Board noted that the National Fund’s contractual management fee rate ranked in the fourth quartile, and that the actual management fee rate and total expense ratio each ranked in the second quartile, relative to the National Fund’s Expense Peers. The Board also noted that the National Fund has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the aggregate assets of the National Fund, combined with the assets of the Short-Term Fund, increase above certain contractually specified levels. The Board further noted that BlackRock has contractually agreed to a cap on the National Fund’s total expenses as a percentage of the Fund’s average daily net assets on a class-by-class basis, as applicable.

The Board noted that the Short-Term Fund’s contractual management fee rate ranked in the first quartile, and that the actual management fee rate and total expense ratio ranked in the first and second quartiles, respectively, relative to the Short-Term Fund’s Expense Peers. The Board also noted that the Short-Term Fund has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the aggregate assets of the Short-Term Fund, combined with the assets of the National Fund, increase above certain contractually specified levels. The Board further noted that BlackRock has voluntarily agreed to a cap on the Short-Term Fund’s total expenses as a percentage of the Short-Term Fund’s average daily net assets on a class-by-class basis, as applicable. The Board noted that the voluntary cap is scheduled to convert to a contractual cap.

The Board noted that the New York Fund’s contractual management fee rate ranked in the third quartile, and that the actual management fee rate and total expense ratio each ranked in the fourth quartile, relative to the New York Fund’s Expense Peers. The Board also noted that the New York Fund has an advisory fee arrangement that includes voluntary breakpoints that adjust the fee rate downward as the size of the New York Fund increases above certain contractually specified levels. After discussion between the Board, including the independent Board Members, and BlackRock, the Board and BlackRock contractually agreed to a cap on the New York Fund’s total expenses as a percentage of the New York Fund’s average daily net assets on a class-by-class basis, as applicable. These reductions, which may result in savings to shareholders, became effective on June 1, 2014.

D. Economies of Scale: The Board, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of each Fund increase, as well as the existence of expense caps, as applicable. The Board also considered the extent to which each Fund benefits from such economies and whether there should be changes in the advisory fee rate or breakpoint structure in order to enable each Fund to participate in these economies of scale, for example through the use of revised breakpoints, or with respect to the New York Fund, through the use of contractual breakpoints and/or revised voluntary breakpoints, in the advisory fee based upon the asset level of the Fund, and in the case of the National Fund and the Short-Term Fund, based on the combined assets of those two funds. In its consideration, the Board Members took into account the existence of any expense caps and further considered the continuation and/or implementation, as applicable, of such caps.

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

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

The Board noted the competitive nature of the open-end fund marketplace, and that shareholders are able to redeem their Fund shares if they believe that each Fund’s fees and expenses are too high or if they are dissatisfied with the performance of the Fund.

Conclusion

The Board, including the Independent Board Members, approved the continuation of the Advisory Agreements between the Manager and the Corporation, on behalf of the High Yield Fund, the National Fund and the Short-Term Fund, and the Trust, on behalf of the New York Fund, for a one year term ending June 30, 2015. Based upon its evaluation of all of the aforementioned factors in their totality, the Board, including the Independent Board Members, was 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 its decision to approve the Agreements, the Board 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. As a result, the Board Members’ conclusions may be based in part on their consideration of these arrangements in prior years.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

The Committee has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the Investment Adviser and Fund Service Providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are (a) consistent with the SEC’s auditor independence rules and (b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis (“general pre-approval”). The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period. Tax or other non-audit services provided to the registrant which have a direct impact on the operations or financial reporting of the registrant will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrant or $50,000 per project. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to the Committee Chairman the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by the Committee pursuant to the de minimis exception in paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g) The aggregate non-audit fees paid to the accountant for services rendered by the accountant to the registrant, the Investment Adviser and the Fund Service Providers were:

Entity Name	Current Fiscal Year End	Previous Fiscal Year End
BlackRock High Yield Municipal Fund	$12,600	$12,600
BlackRock National Municipal Fund	$12,600	$12,600
BlackRock Short-Term Municipal Fund	$12,600	$12,600

Additionally, SSAE 16 Review (Formerly, SAS No. 70) fees for the current and previous fiscal years of $2,555,000 and $2,865,000, respectively, were billed by D&T to the Investment Adviser.

(h) The Committee has considered and determined that the provision of non-audit services that were rendered to the Investment Adviser and the Fund Service Providers that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.
