The Markets in Review

Dear Shareholder,

U.S. equities and bonds both delivered impressive returns over the last 12 months, despite fears and doubts about the economy that were ultimately laid to rest with unprecedented monetary stimulus and a sluggish yet resolute performance from the U.S. economy. Investors were further encouraged by the apparent cessation of trade hostilities between the United States and China late in 2019, although some of these gains were reversed in January 2020, as the spread of the coronavirus injected uncertainty into markets.

Returns for most securities were particularly strong in the second half of the reporting period, as investors began to realize that the U.S. economy was maintaining the modest yet steady growth that has characterized this economic cycle. In the United States, large-cap stocks led the broader market, while small-cap equities still posted healthy returns. Emerging market stocks, however, were constrained by coronavirus fears, losing most of their gains near the end of the reporting period.

Fixed-income securities played an important role in diversified portfolios by delivering strong returns amid economic uncertainty, as interest rates declined (and bond prices rose). Long-term bonds, particularly long-term Treasuries, generally posted the strongest returns, as inflation remained low despite an uptick late in the reporting period. Investment-grade and high-yield corporate bonds also posted solid returns, as the credit fundamentals in corporate markets remained relatively solid.

Continuing the shift toward looser monetary policy that began in early 2019, the U.S. Federal Reserve (the “Fed”) increased efforts to stimulate economic activity. The Fed reduced interest rates three times during the reporting period, from July 2019 to October 2019. In December 2019, the Fed further reassured markets by indicating that it is unlikely to reverse course and tighten monetary policy in the near future. Following in the Fed’s footsteps, the European Central Bank announced aggressive economic stimulus measures, including lower interest rates and the return of its bond purchasing program. The Bank of Japan continued its accommodative monetary policy, while China committed to looser credit conditions and an increase in fiscal spending.

The outpouring of global economic stimulus led to a sharp rally in risk assets throughout the world despite the headwind of rising geopolitical and trade tensions. Hopes continued to remain high as the current economic expansion became the longest in U.S. history.

Looking ahead, we believe there are reasons to remain cautious about the U.S. economy, most notably the uncertainty around the duration of the impact of the coronavirus-driven economic contraction, the U.S. presidential election and future earnings growth. At this time we are watching the developments around the world very closely to assess the full extent of the risks of economic disruption that could result from the global pandemic. Corporate earnings underperformed in 2019, but action by the Fed led to outstanding equity returns. With the future of monetary policy and consumer behaviors uncertain, earnings deterioration could act as a drag on equities.

Overall, we favor moderately increasing investment risk to benefit from expected growth. We are neutral on U.S. equities, but we favor emerging market and Japanese equities, which could benefit from an uptick in global trade and investment. Increasing cyclical exposure through value-style investing and maintaining a meaningful emphasis on high-quality companies through quality factors also makes sense for diversified investors. In fixed income, extremely low yields and inflation risk limit the effectiveness of many bond classes as a counterweight in portfolios. We favor higher-yielding bonds from emerging markets, where central banks have more room for further accommodation, while strategically using U.S. Treasuries as stabilizers.

In this environment, investors need to think globally, extend their scope across a broad array of asset classes, and be nimble as market conditions change. We encourage you to talk with your financial advisor and visit blackrock.com for further insight about investing in today’s markets.

Sincerely,

Municipal Market Overview For the Reporting Period Ended January 31, 2020

Municipal Market Conditions


Municipal bonds posted strong total returns during the period, buoyed by a combination of rallying interest rates and a favorable technical backdrop. Interest rates moved lower in 2019 as the Fed turned more dovish on the back of slowing global growth and trade uncertainties, indicated a commitment to sustain the current economic expansion, and executed a mid-cycle adjustment consisting of three 0.25% rate cuts. This dynamic was compounded in early 2020 as elevated event risks, led by increased U.S. conflict with Iran and a coronavirus pandemic, spurred a flight to quality. At the same time,		S&P Municipal Bond Index Total Returns as of January 31, 2020 6 months: 3.08% 12 months: 8.21%

municipal bond technicals remained supportive with historically robust demand outpacing moderate supply. During the 12 months ended January 31, 2020, municipal bond funds experienced net inflows totaling $98 billion (based on data from the Investment Company Institute). Broadly, investors favored the tax-exempt income, diversification, quality, and value of municipal bonds given that tax reform ultimately lowered the top individual tax rate just 2.6% while eliminating deductions. For the same 12-month period, total new issuance was slightly above average from a historical perspective at $409 billion, but was boosted by robust taxable municipal supply. Taxable municipal bond issuance picked up late in 2019, as issuers advance refunded tax-exempt debt using taxable municipal bonds for cost savings. While increasing issuance totals, this dynamic ultimately shrank the size of the tax-exempt market and provided a positive technical tailwind for the natural buyer of the asset class.

A Closer Look at Yields

LOGO

From January 31, 2019 to January 31, 2020, yields on AAA-rated 30-year municipal bonds decreased by 122 basis points (“bps”) from 3.02% to 1.80%, while ten-year rates decreased by 102 bps from 2.17% to 1.15% and five-year rates decreased by 92 bps from 1.76% to 0.84% (as measured by Thomson Municipal Market Data). As a result, the municipal yield curve flattened over the 12-month period with the spread between two- and 30-year maturities flattening by 40 bps, compared to 14 bps of steepening in the comparable U.S. Treasury curve.

During the same time period, tax-exempt municipal bonds outperformed duration-matched U.S. Treasuries, most notably in the long end of the yield curve. Consequently, relative valuations remained stretched versus history. Given that the corporate tax rate was lowered much more than the individual rate, institutions now have less incentive to own tax-exempt municipal bonds, while individuals are more incentivized. In a more retail-driven market, lower municipal-to-Treasury ratios are likely sustainable as individuals are focused more on generating tax-free income and less concerned with relative valuations. The asset class is known for its lower relative volatility and preservation of principal with an emphasis on income as tax rates rise.

Financial Conditions of Municipal Issuers

Most states and localities are on solid footing as tax receipts are increasing steadily and spending levels are rebounding from post-recession lows. Rising healthcare expenditures and legacy pension costs are plaguing a handful of high-profile credits. Essential service revenue bonds continue to benefit from deleveraging. Several private-public partnerships and off-balance sheet projects have made headlines for cost-overruns that are calling into question their value add. More caution is warranted in the non-profit sectors, especially less-selective private education credits that are dealing with competitive pressures and are burdened with outsized debt. Merger and acquisition activity has been elevated in the hospital sector, providing opportunities to generate performance. Additionally, high yield remains an important driver of performance. BlackRock maintains the view that municipal bond defaults will remain minimal and the overall market is fundamentally sound. However, we continue to advocate careful credit research and believe that a thoughtful approach to structure and security selection remains imperative amid uncertainty in a modestly improving economic environment.

The opinions expressed are those of BlackRock as of January 31, 2020 and are subject to change at any time due to changes in market or economic conditions. The comments should not be construed as a recommendation of any individual holdings or market sectors. Investing involves risk including loss of principal. Bond values fluctuate in price so the value of your investment can go down depending on market conditions. Fixed income risks include interest-rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments. There may be less information on the financial condition of municipal issuers than for public corporations. The market for municipal bonds may be less liquid than for taxable bonds. Some investors may be subject to Alternative Minimum Tax (“AMT”). Capital gains distributions, if any, are taxable.

The S&P Municipal Bond Index, a broad, market value-weighted index, seeks to measure the performance of the U.S. municipal bond market. All bonds in the index are exempt from U.S. federal income taxes or subject to the AMT. Past performance is no guarantee of future results. Index performance is shown for illustrative purposes only. It is not possible to invest directly in an index.


4		2020 BLACKROCK SEMI-ANNUAL REPORT TO SHAREHOLDERS

The Benefits and Risks of Leveraging

The Trusts may utilize leverage to seek to enhance the distribution rate on, and net asset value (“NAV”) of, their common shares (“Common Shares”). However, there is no guarantee that these objectives can be achieved in all interest rate environments.

In general, the concept of leveraging is based on the premise that the financing cost of leverage, which is based on short-term interest rates, is normally lower than the income earned by a Trust on its longer-term portfolio investments purchased with the proceeds from leverage. To the extent that the total assets of the Trusts (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, the Trusts’ shareholders benefit from the incremental net income. The interest earned on securities purchased with the proceeds (after paying the leverage costs) from leverage is paid to shareholders in the form of dividends, and the value of these portfolio holdings (less the leverage liability) is reflected in the per share NAV.

To illustrate these concepts, assume a Trust’s Common Shares capitalization is $100 million and it utilizes leverage for an additional $30 million, creating a total value of $130 million available for investment in longer-term income securities. If prevailing short-term interest rates are 3% and longer-term interest rates are 6%, the yield curve has a strongly positive slope. In this case, a Trust’s financing costs on the $30 million of proceeds obtained from leverage are based on the lower short-term interest rates. At the same time, the securities purchased by a Trust with the proceeds from leverage earn income based on longer-term interest rates. In this case, a Trust’s financing cost of leverage is significantly lower than the income earned on a Trust’s longer-term investments acquired from such leverage proceeds, and therefore the holders of Common Shares (“Common Shareholders”) are the beneficiaries of the incremental net income.

However, in order to benefit Common Shareholders, the return on assets purchased with leverage proceeds must exceed the ongoing costs associated with the leverage. If interest and other costs of leverage exceed the Trusts’ return on assets purchased with leverage proceeds, income to shareholders is lower than if the Trusts had not used leverage. Furthermore, the value of the Trusts’ portfolio investments generally varies inversely with the direction of long-term interest rates, although other factors can influence the value of portfolio investments. In contrast, the value of the Trusts’ obligations under their respective leverage arrangements generally does not fluctuate in relation to interest rates. As a result, changes in interest rates can influence the Trusts’ NAVs positively or negatively. Changes in the future direction of interest rates are very difficult to predict accurately, and there is no assurance that the Trusts’ intended leveraging strategy will be successful.

The use of leverage also generally causes greater changes in each Trust’s NAV, market price and dividend rates than comparable portfolios without leverage. In a declining market, leverage is likely to cause a greater decline in the NAV and market price of a Trust’s Common Shares than if the Trust were not leveraged. In addition, each Trust may be required to sell portfolio securities at inopportune times or at distressed values in order to comply with regulatory requirements applicable to the use of leverage or as required by the terms of leverage instruments, which may cause the Trusts to incur losses. The use of leverage may limit a Trust’s ability to invest in certain types of securities or use certain types of hedging strategies. Each Trust incurs expenses in connection with the use of leverage, all of which are borne by Common Shareholders and may reduce income to the Common Shares. Moreover, to the extent the calculation of the Trusts’ investment advisory fees includes assets purchased with the proceeds of leverage, the investment advisory fees payable to the Trusts’ investment adviser will be higher than if the Trusts did not use leverage.

To obtain leverage, each Trust has issued Variable Rate Demand Preferred Shares (“VRDP Shares”), Variable Rate Muni Term Preferred Shares (“VMTP Shares”) or Remarketable Variable Rate Muni Term Preferred Shares (“RVMTP Shares”) (collectively, “Preferred Shares”) and/or leveraged its assets through the use of tender option bond trusts (“TOB Trusts”) as described in the Notes to Financial Statements.

Under the Investment Company Act of 1940, as amended (the “1940 Act”), each Trust is permitted to issue debt up to 33 1/3% of its total managed assets or equity securities (e.g., Preferred Shares) up to 50% of its total managed assets. A Trust may voluntarily elect to limit its leverage to less than the maximum amount permitted under the 1940 Act. In addition, a Trust may also be subject to certain asset coverage, leverage or portfolio composition requirements imposed by the Preferred Shares’ governing instruments or by agencies rating the Preferred Shares, which may be more stringent than those imposed by the 1940 Act.

If a Trust segregates or designates on its books and records cash or liquid assets having a value not less than the value of a Trust’s obligations under the TOB Trust (including accrued interest), then the TOB Trust is not considered a senior security and is not subject to the foregoing limitations and requirements imposed by the 1940 Act.

Derivative Financial Instruments

The Trusts may invest in various derivative financial instruments. These instruments are used to obtain exposure to a security, commodity, index, market, and/or other assets without owning or taking physical custody of securities, commodities and/or other referenced assets or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage and 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 instrument. The Trusts’ successful use of a derivative financial instrument depends on the investment adviser’s ability to predict pertinent market movements accurately, which cannot be assured. The use of these instruments may result in losses greater than if they had not been used, may limit the amount of appreciation a Trust can realize on an investment and/or may result in lower distributions paid to shareholders. The Trusts’ investments in these instruments, if any, are discussed in detail in the Notes to Financial Statements.

Trust Summary as of January 31, 2020		BlackRock California Municipal Income Trust

Trust Overview

BlackRock California Municipal Income Trust’s (BFZ) (the “Trust”) investment objective is to provide current income exempt from regular U.S. federal income and California income taxes. The Trust seeks to achieve its investment objective by investing primarily in municipal obligations exempt from U.S. federal income taxes (except that the interest may be subject to the federal alternative minimum tax) and California income taxes. The Trust invests, under normal market conditions, at least 80% of its assets in municipal obligations that are investment grade quality, or are considered by the Trust’s investment adviser to be of comparable quality, at the time of investment. The Trust may invest directly in securities or synthetically through the use of derivatives.

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

The following discussion relates to the Trust’s absolute performance based on NAV:

After moving sideways for much of the period, municipal bonds finished with positive returns thanks to their rally in January. In fact, January represented the highest one-month return for U.S. municipal issues in six years (as measured by the S&P Municipal Bond Index). The gains for the broader bond market reflected the backdrop of weaker economic data and worries about the spread of coronavirus. (Bond prices rise as yields fall.) The favorable combination of robust investor demand and relatively limited new-issue supply also provided an additional tailwind for tax-exempt securities.

California municipal debt finished slightly ahead of the national index, as the repeal of federal, state and local tax deductions fueled continued demand in high-tax states.

The Trust sought to manage interest rate risk using U.S. Treasury futures. Given that U.S. Treasury yields fell, as prices rose, this strategy detracted from Trust performance. Conversely, the Trust benefited from its position in longer-duration securities. (Duration is a measure of interest-rate sensitivity.) At the sector level, positions in transportation, tax-backed local, school district, utility and education issues provided the strongest returns.

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.

The favorable combination of robust investor demand and relatively limited new-issue supply also provided a tailwind for the tax-exempt market.

Positions in high yield debt, which outperformed on the strength of solid credit fundamentals and investors’ appetite for yield, contributed to Trust performance. The Trust’s holdings in Puerto Rico were particularly strong performers. At the sector level, health care, transportation and tobacco issues were key contributors. In addition, the Trust’s use of leverage aided results by enhancing income and amplifying the effect of rising prices. On the negative side, reinvestment risk remained a headwind since as the proceeds from bonds that matured or were called needed to be reinvested at lower yields compared to bonds that were issued when yields were higher.

^(a)

For financial reporting purposes, credit quality ratings shown above reflect the highest rating assigned by either S&P Global Ratings or 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.

^(b)

The investment adviser 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 adviser has deemed certain of these unrated securities as investment grade quality. As of January 31, 2020 and July 31, 2019, the market value of unrated securities deemed by the investment adviser to be investment grade represents less than 1% of the Trust’s total investments.

^(a)

All returns reflect reinvestment of dividends and/or distributions at actual reinvestment prices.

^(b)

The Trust moved from a premium to NAV to a discount during the period, which accounts for the difference between performance based on market price and performance based on NAV.

^(c)

Average return. Returns reflect reinvestment of dividends and/or distributions at NAV on the ex-dividend date as calculated by Lipper.

Performance results may include adjustments made for financial reporting purposes in accordance with U.S. generally accepted accounting principles.

Past performance is no guarantee of future results.

The following discussion relates to the Trust’s absolute performance based on NAV:

After moving sideways for much of the period, municipal bonds finished with positive returns thanks to their rally in January. In fact, January represented the highest one-month return for U.S. municipal issues in six years (as measured by the S&P Municipal Bond Index). The gains for the broader bond market reflected the backdrop of weaker economic data and worries about the spread of coronavirus. (Bond prices rise as yields fall.) The favorable combination of robust investor demand and relatively limited new-issue supply provided an additional tailwind for tax-exempt securities.

An allocation to bonds with maturities of 20 years and above helped Trust performance, as longer-term issues outperformed. The Trust’s use of leverage aided results by enhancing income and amplifying the effect of rising prices. At the sector level, state tax-backed and health care issues were strong contributors. Performance in the tax-backed space was highlighted by strength in Puerto Rico bonds backed by sales taxes. Positions in BBB, AA and A rated debt further contributed.

The Trust sought to manage interest rate risk using U.S. Treasury futures. Since U.S. Treasury yields fell, as prices rose, this strategy detracted from Trust performance. Reinvestment risk continued to be a headwind since the proceeds from bonds that matured or were called needed to be reinvested at lower yields compared to bonds that were issued when yields were higher. In addition, positions in shorter-term bonds lagged relative to those with longer-dated maturities.

Trust Summary as of January 31, 2020		BlackRock New York Municipal Income Trust

Trust Overview

BlackRock New York Municipal Income Trust’s (BNY) (the “Trust”) investment objective is to provide current income exempt from regular U.S. federal income tax and New York State and New York City personal income taxes. The Trust seeks to achieve its investment objective by investing primarily in municipal bonds exempt from U.S. federal income taxes (except that the interest may be subject to the federal alternative minimum tax) and New York State and New York City personal income taxes. The Trust invests at least 80% of its assets in municipal bonds that are investment grade quality, or are considered by the Trust’s investment adviser to be of comparable quality, at the time of investment. The Trust may invest directly in securities or synthetically through the use of derivatives.

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

^(b)

Tax equivalent yield assumes the maximum marginal U.S. federal and state tax rate of 49.62%, which includes the 3.8% Medicare tax. Actual tax rates will vary based on income, exemptions and deductions. Lower taxes will result in lower tax equivalent yields.

^(c)

The monthly distribution per Common Share, declared on March 2, 2020, was increased to $0.0480 per share. The yield on closing market price, tax equivalent yield, current monthly distribution per Common Share, and current annualized distribution per Common Share do not reflect the new distribution rate. The distribution rate is not constant and is subject to change in the future. A portion of the distribution may be deemed a return of capital or net realized gain.

The following discussion relates to the Trust’s absolute performance based on NAV:

After moving sideways for much of the period, municipal bonds finished with positive returns thanks to their rally in January. In fact, January represented the highest one-month return for U.S. municipal issues in six years (as measured by the S&P Municipal Bond Index). The gains for the broader bond market reflected the backdrop of weaker economic data and worries about the spread of coronavirus. (Bond prices rise as yields fall.) The favorable combination of robust investor demand and relatively limited new-issue supply provided an additional tailwind for tax-exempt securities.

Trends in the New York market reflected those on the national level, with falling yields, strong inflows, and limited new-issue supply. While the state underperformed the broader U.S. market, New York still produced a solid return as investors in high-tax states continued to seek shelter in tax-exempt bonds.

On the positive side, an allocation to bonds with maturities of 20 years and above helped performance. The Trust’s use of leverage aided results by enhancing income and amplifying the effect of rising prices. At the sector level, state tax-backed, local tax-backed and transportation issues were strong contributors. Performance in the tax-backed space was highlighted by strength in Puerto Rico bonds backed by sales taxes. Positions in AA and A rated debt further contributed to Trust performance.

50		2020 BLACKROCK SEMI-ANNUAL REPORT TO SHAREHOLDERS

Notes to Financial Statements (unaudited)

1.	*ORGANIZATION*

The following are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as closed-end management investment companies and are referred to herein collectively as the “Trusts”, or individually as a “Trust”:


Trust Name	Herein Referred To As	Organized	Diversification Classification
BlackRock California Municipal Income Trust	BFZ	Delaware	Diversified
BlackRock Municipal 2030 Target Term Trust	BTT	Delaware	Diversified
BlackRock Municipal Income Investment Trust	BBF	Delaware	Diversified
BlackRock New York Municipal Income Trust	BNY	Delaware	Diversified

The Board of Trustees of the Trusts are collectively referred to throughout this report as the “Board of Trustees” or the “Board,” and the trustees thereof are collectively referred to throughout this report as “Trustees”. The Trusts determine and make available for publication the net asset values (“NAVs”) of their Common Shares on a daily basis.

The Trusts, together with certain other registered investment companies advised by BlackRock Advisors, LLC (the “Manager”) or its affiliates, are included in a complex of non-index fixed-income mutual funds and all BlackRock-advised closed-end funds referred to as the BlackRock Fixed-Income Complex.

2.	*SIGNIFICANT ACCOUNTING POLICIES*

The 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, disclosure of contingent assets and liabilities at the date of 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 Trust is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. Below is a summary of significant accounting policies:

Investment Transactions and Income Recognition: For financial reporting purposes, investment transactions are recorded on the dates the transactions are executed. Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income, including amortization and accretion of premiums and discounts on debt securities, are recognized on an accrual basis.

Segregation and Collateralization: In cases where a Trust enters into certain investments (e.g. futures contracts) or certain borrowings (e.g. TOB Trust transactions) that would be treated as “senior securities” for 1940 Act purposes, a Trust may segregate or designate on its books and records cash or liquid assets having a market value at least equal to the amount of its future obligations under such investments or borrowings. Doing so allows the investment or borrowings to be excluded from treatment as a “senior security.” Furthermore, if required by an exchange or counterparty agreement, the Trusts 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.

Distributions: Distributions from net investment income are declared monthly and paid monthly. Distributions of capital gains are recorded on the ex-dividend date and made at least annually. The portion of distributions, if any, that exceeds a fund’s current and accumulated earnings and profits, as measured on a tax basis, constitute a non-taxable return of capital. The character and timing of distributions are determined in accordance with U.S. federal income tax regulations, which may differ from U.S. GAAP.

Deferred Compensation Plan: Under the Deferred Compensation Plan (the “Plan”) approved by each Board of Trustees of the Trusts (the “Board”), the trustees who are not “interested persons” of the Trusts, as defined in the 1940 Act, (“Independent Trustees”), may defer a portion of their annual complex-wide compensation. Deferred amounts earn an approximate return as though equivalent dollar amounts had been invested in common shares of certain funds in the BlackRock Fixed-Income Complex selected by the Independent Trustees. This has the same economic effect for the Independent Trustees as if the Independent Trustees had invested the deferred amounts directly in certain funds in the BlackRock Fixed-Income Complex.

The Plan is not funded and obligations thereunder represent general unsecured claims against the general assets of each Trust, if applicable. Deferred compensation liabilities are included in the Trustees’ and Officer’s fees payable in the Statements of Assets and Liabilities and will remain as a liability of the Trusts until such amounts are distributed in accordance with the Plan.

Recent Accounting Standards: The Trusts have adopted Financial Accounting Standards Board Accounting Standards Update 2017-08 to amend the amortization period for certain purchased callable debt securities held at a premium. Under the new standard, the trusts have changed the amortization period for the premium on certain purchased callable debt securities with non-contingent call features to the earliest call date. In accordance with the transition provisions of the standard, the Trusts applied the amendments on a modified retrospective basis beginning with the fiscal period ended January 31, 2020. The adjusted cost basis of securities at July 31, 2019 are as follows:


BFZ	$	788,792,864
BTT		2,636,048,610
BBF		234,804,000
BNY		307,160,539

This change in accounting policy has been made to comply with the newly issued accounting standard and had no impact on accumulated earnings (loss) or the net asset value of the Trusts.


NOTES TO FINANCIAL STATEMENTS			51

Notes to Financial Statements (unaudited) (continued)

Indemnifications: In the normal course of business, a Trust enters into contracts that contain a variety of representations that provide general indemnification. A Trust’s maximum exposure under these arrangements is unknown because it involves future potential claims against a Trust, which cannot be predicted with any certainty.

Other: Expenses directly related to a Trust are charged to that Trust. Other operating expenses shared by several funds, including other funds managed by the Manager, are prorated among those funds on the basis of relative net assets or other appropriate methods.

3.	*INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS*

Investment Valuation Policies: The Trusts’ investments are valued at fair value (also referred to as “market value” within the financial statements) as of the close of trading on the New York Stock Exchange (“NYSE”) (generally 4:00 p.m., Eastern time). U.S. GAAP defines fair value as the price the Trusts would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Trusts determine the fair values of their financial instruments using various independent dealers or pricing services under policies approved by the Board of Trustees of each Trust (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 oversee the pricing function for all financial instruments.

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of each Trust’s assets and liabilities:

•

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.

•

Investments in open-end U.S. mutual funds are valued at NAV each business day.

•

Futures contracts traded on exchanges are valued at their last sale price.

If events (e.g., a company announcement, market volatility or a natural disaster) occur that are expected to materially affect the value of such investments, or 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 Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee will include market approach, income approach and cost approach. Valuation techniques such as discounted cash flow, use of market comparables and matrix pricing are types of valuation approaches and are typically used in determining fair value. When determining the price for Fair Valued Investments, the Global Valuation Committee, or its delegate, seeks to determine the price that each Trust might reasonably expect to receive or pay from the current sale or purchase of that asset or liability 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 and consistent with the principles of fair value measurement. The pricing of all Fair Valued Investments is subsequently reported to the Board or a committee thereof on a quarterly basis.

Fair Value Hierarchy: Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs to valuation techniques are categorized into a fair value 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 each Trust 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 Global Valuation Committee’s 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. Investments classified within Level 3 have significant unobservable inputs used by the Global Valuation Committee in determining the price for Fair Valued Investments. Level 3 investments include equity or debt issued by privately held companies or funds. There may not be a secondary market, and/or there are a limited number of investors. The categorization of a value determined for investments and derivative financial instruments is based on the pricing transparency of the investments and derivative financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

4.	*SECURITIES AND OTHER INVESTMENTS*

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

Forward Commitments, When-Issued and Delayed Delivery Securities: Certain trusts may purchase securities on a when-issued basis and may purchase or sell securities on a forward commitment basis. Settlement of such transactions normally occurs within a month or more after the purchase or sale commitment is made. A trust 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, a trust may be required to pay more at settlement than the security is worth. In


52		2020 BLACKROCK SEMI-ANNUAL REPORT TO SHAREHOLDERS

Notes to Financial Statements (unaudited) (continued)

addition, a trust is not entitled to any of the interest earned prior to settlement. When purchasing a security on a delayed delivery basis, a trust assumes 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, a trust’s maximum amount of loss is the unrealized appreciation of unsettled when-issued transactions.

Municipal Bonds Transferred to TOB Trusts: Certain trusts leverage their assets through the use of “TOB Trust” transactions. The trusts transfer municipal bonds into a special purpose trust (a “TOB Trust”). A TOB Trust issues two classes of beneficial interests: short-term floating rate interests (“TOB Trust Certificates”), which are sold to third party investors, and residual inverse floating rate interests (“TOB Residuals”), which are issued to the participating trusts that contributed the municipal bonds to the TOB Trust. The TOB Trust Certificates have interest rates that reset weekly and their holders have the option to tender such certificates to the TOB Trust for redemption at par and any accrued interest at each reset date. The TOB Residuals held by a trust provides the trust with the right to cause the holders of a proportional share of the TOB Trust Certificates to tender their certificates to the TOB Trust at par plus accrued interest. The trust may withdraw a corresponding share of the municipal bonds from the TOB Trust. Other trusts managed by the investment adviser may also contribute municipal bonds to a TOB Trust into which a trust has contributed bonds. If multiple BlackRock-advised funds participate in the same TOB Trust, the economic rights and obligations under the TOB Residuals will be shared among the trusts ratably in proportion to their participation in the TOB Trust.

TOB Trusts are supported by a liquidity facility provided by a third party 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 of par plus accrued interest on any business day. The tendered TOB Trust Certificates are remarketed by a Remarketing Agent. In the event of a failed remarketing, the TOB Trust may draw upon a loan from the Liquidity Provider to purchase the tendered TOB Trust Certificates. Any loans made by the Liquidity Provider will be secured by the purchased TOB Trust Certificates held by the TOB Trust and will be subject to an increased interest rate based on number of days the loan is outstanding.

The TOB Trust may be collapsed without the consent of a trust, upon the occurrence of a termination event, as defined in the TOB Trust agreement. Upon the occurrence of a termination event, a TOB Trust would be liquidated with the proceeds applied first to any accrued fees owed to the trustee of the TOB Trust, the Remarketing Agent and the Liquidity Provider. Upon certain termination events, TOB Trust Certificates holders will be paid before the TOB Residuals holders (i.e., the Trusts) whereas in other termination events, TOB Trust Certificates holders and TOB Residuals holders will be paid pro rata.

While a trust’s investment policies and restrictions expressly permit investments in inverse floating rate securities, such as TOB Residuals, they restrict the ability of a trust to borrow money for purposes of making investments. Each trust’s transfer of the municipal bonds to a TOB Trust is considered a secured borrowing for financial reporting purposes. The cash received by the TOB Trust from the sale of the TOB Trust Certificates, less certain transaction expenses, is paid to a trust. A trust typically invests the cash received in additional municipal bonds.

Accounting for TOB Trusts: The municipal bonds deposited into a TOB Trust are presented in a trust’s Schedule of Investments and the TOB Trust Certificates are shown in Other Liabilities in the Statements of Assets and Liabilities. Any loans drawn by the TOB Trust pursuant to the liquidity facility to purchase tendered TOB Trust Certificates are shown as Loan for TOB Trust Certificates. The carrying amount of a trust’s payable to the holder of the TOB Trust Certificates, as reported in the Statements of Assets and Liabilities as TOB Trust Certificates, approximates its fair value.

Interest income, including amortization and accretion of premiums and discounts, from the underlying municipal bonds is recorded by a Trust on an accrual basis. Interest expense incurred on the TOB Trust transaction and other expenses related to remarketing, administration, trustee, liquidity and other services to a TOB Trust are shown as interest expense, fees and amortization of offering costs in the Statements of Operations. Fees paid upon creation of the TOB Trust are recorded as debt issuance costs and are amortized to interest expense, fees and amortization of offering costs in the Statements of Operations to the expected maturity of the TOB Trust. In connection with the restructurings of the TOB Trusts to non-bank sponsored TOB Trusts, a Trust incurred non-recurring, legal and restructuring fees, which are recorded as interest expense, fees and amortization of deferred offering costs in the Statements of Operations.

Amounts recorded within interest expense, fees and amortization of offering costs in the Statements of Operations are:


	Interest Expense		Liquidity Fees		Other Expense		Total
BFZ	$	925,241	$	341,910	$	103,126	$	1,370,277
BTT		1,705,590		429,051		360,575		2,495,216
BBF		224,389		71,393		32,026		327,808
BNY		237,214		82,658		23,261		343,133

For the six months ended January 31, 2020, the following table is a summary of each Trust’s TOB Trusts:


	Underlying Municipal Bonds Transferred to TOB Trusts^(a)		Liability for TOB Trust Certificates^(b)		Range of Interest Rates on TOB Trust Certificates at Period End		Average TOB Trust Certificates Outstanding		Daily Weighted Average Rate of Interest and Other Expenses on TOB Trusts
BFZ . . .	$	383,340,621	$	171,438,735		0.90% — 1.19%	$	148,620,870		1.83	%
BTT . . .		461,502,371		261,819,915		0.97% — 1.09%		261,819,915		1.90
BBF . . .		76,452,792		42,889,056		0.94% — 1.12%		35,645,161		1.83
BNY . . .		72,074,447		38,865,798		0.95% — 1.09%		37,264,278		1.83

^(a)

The municipal bonds transferred to a TOB Trust are generally high grade municipal bonds. In certain cases, when municipal bonds transferred are lower grade municipal bonds, the TOB Trust transaction may include a credit enhancement feature that provides for the timely payment of principal and interest on the bonds to the TOB Trust by a credit


NOTES TO FINANCIAL STATEMENTS			53

Notes to Financial Statements (unaudited) (continued)

enhancement provider in the event of default of the municipal bond. The TOB Trust would be responsible for the payment of the credit enhancement fee and the trusts, as TOB Residuals holders, would be responsible for reimbursement of any payments of principal and interest made by the credit enhancement provider. The maximum potential amounts owed by the trusts, for such reimbursements, as applicable, are included in the maximum potential amounts disclosed for recourse TOB Trusts.

^(b)

TOB Trusts may be structured on a non-recourse or recourse basis. When a Trust invests in TOB Trusts on a non-recourse basis, the Liquidity Provider may be required to make a payment under the liquidity facility to allow the TOB Trust to repurchase TOB Trust Certificates. The Liquidity Provider will be reimbursed from the liquidation of bonds held in the TOB Trust. If the trust invests in a TOB Trust on a recourse basis, the trust enters into a reimbursement agreement with the Liquidity Provider where the trust is required to reimburse the Liquidity Provider for any shortfall between the amount paid by the Liquidity Provider and proceeds received from liquidation of municipal bonds held in the TOB Trust (the “Liquidation Shortfall”). As a result, if the trust invests in a recourse TOB Trust, the trust will bear the risk of loss with respect to any Liquidation Shortfall. If multiple funds participate in any such TOB Trust, these losses will be shared ratably, including the maximum potential amounts owed by the trust at January 31, 2020, in proportion to their participation in the TOB Trust. The recourse TOB Trusts are identified in the Schedule of Investments including the maximum potential amounts owed by the trust at January 31, 2020.

5.	*DERIVATIVE FINANCIAL INSTRUMENTS*

The Trusts engage in various portfolio investment strategies using derivative contracts both to increase the returns of the Trusts and/or to manage their exposure to certain risks such as credit risk, equity risk, interest rate risk, foreign currency exchange rate risk, commodity price risk or other risks (e.g., inflation risk). Derivative financial instruments categorized by risk exposure are included in the Schedules of Investments. These contracts may be transacted on an exchange or over-the-counter.

Futures Contracts: Futures contracts are purchased or sold to gain exposure to, or manage exposure to, changes in interest rates (interest rate risk) and changes in the value of equity securities (equity risk) or foreign currencies (foreign currency exchange rate risk).

Futures contracts are agreements between the Trusts and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and on a specified date. Depending on the terms of a contract, it is settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash amount on the settlement date. Upon entering into a futures contract, the Trusts 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. Amounts pledged, which are considered restricted, are included in cash pledged for futures contracts in the Statements of Assets and Liabilities.

Securities deposited as initial margin are designated in the Schedules of Investments and cash deposited, if any, is shown as cash pledged for futures contracts in the Statements of Assets and Liabilities. Pursuant to the contract, the Trusts agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in market value of the contract (“variation margin”). Variation margin is recorded as unrealized appreciation (depreciation) and, if any, shown as variation margin receivable (or payable) on futures contracts in the Statements of Assets and Liabilities. When the contract is closed, a realized gain or loss is recorded in the Statements of Operations equal to the difference between the notional amount of the contract at the time it was opened and the notional amount at the time it was closed. The use of futures contracts involves the risk of an imperfect correlation in the movements in the price of futures contracts and interest, foreign currency exchange rates or underlying assets.

6.	*INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES*

Investment Advisory: Each Trust entered into an Investment Advisory Agreement with the Manager, the Trusts’ investment adviser and an indirect, wholly-owned subsidiary of BlackRock, Inc. (“BlackRock”), to provide investment advisory and administrative services. The Manager is responsible for the management of each Trust’s portfolio and provides the personnel, facilities, equipment and certain other services necessary to the operations of each Trust.

For such services, each Trust, except BTT, pays the Manager a monthly fee at an annual rate equal to the following percentages of the average weekly value of each Trust’s managed assets.


	BFZ			BBF			BNY
Investment advisory fees		0.58	%		0.57	%		0.60	%

For such services, BTT pays the Manager a monthly fee at an annual rate equal to 0.40% of the average daily value of the Trust’s managed assets.

For purposes of calculating these fees, “managed assets” are determined as total assets of the Trust (including any assets attributable to money borrowed for investment purposes) less the sum of its accrued liabilities (other than money borrowed for investment purposes).

Expense Waivers: With respect to each Trust, the Manager contractually agreed to waive its investment advisory fees by the amount of investment advisory fees each Trust pays to the Manager indirectly through its investment in affiliated money market funds (the “affiliated money market fund waiver”) through June 30, 2021. The contractual agreement may be terminated upon 90 days’ notice by a majority of the Independent Trustees, or by a vote of a majority of the outstanding voting securities of a Trust. Prior to December 1, 2019, this waiver was voluntary. For the six months ended January 31, 2020, the amounts waived were as follows:


	BFZ		BTT		BBF		BNY
Amounts waived	$	843	$	1,771	$	1,199	$	113

The Manager contractually agreed to waive its investment advisory fee with respect to any portion of each Trust’s assets invested in affiliated equity and fixed-income mutual funds and affiliated exchange-traded funds that have a contractual management fee through June 30, 2021. The agreement can be renewed for annual periods thereafter, and may be terminated on 90 days’ notice, each subject to approval by a majority of the Trust’s Independent Trustees. For the six months ended January 31, 2020, there were no fees waived by the Manager pursuant to these arrangements.

Notes to Financial Statements (unaudited) (continued)

Trustees and Officers: Certain trustees and/or officers of the Trusts are directors and/or officers of BlackRock or its affiliates. The Trusts reimburse the Manager for a portion of the compensation paid to the Trusts’ Chief Compliance Officer, which is included in Trustees and Officer in the Statements of Operations.

Other Transactions: The Trusts may purchase securities from, or sell securities to, an affiliated fund provided the affiliation is due solely to having a common investment adviser, common officers, or common trustees. For the six months ended January 31, 2020, the purchase and sale transactions and any net realized gains (losses) with an affiliated fund in compliance with Rule 17a-7 under the 1940 Act were as follows:

Sales		184,912,065		76,292,827		66,336,473		21,229,102

8.	*INCOME TAX INFORMATION*

It is each Trust’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute substantially all of its taxable income to its shareholders. Therefore, no U.S. federal income tax provision is required.

Each Trust files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on each Trust’s U.S. federal tax returns generally remains open for each of the four years ended July 31, 2019. The statutes of limitations on each Trust’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 the Trusts as of January 31, 2020, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Trusts’ financial statements.

As of July 31, 2019, the Trusts had non-expiring capital loss carryforwards available to offset future realized capital gains as follows:


BFZ		BTT		BBF		BNY
$	1,242,628	$	24,405,259	$	3,116,059	$	5,375,343

As of January 31, 2020, gross unrealized appreciation and depreciation for investments and derivatives based on cost for U.S. federal income tax purposes were as follows:


	BFZ			BTT			BBF			BNY
Tax cost	$	612,866,865		$	2,386,695,407		$	184,754,391		$	266,015,253

Net unrealized appreciation	$	58,306,532		$	225,681,426		$	18,540,541		$	26,667,269

9.	*PRINCIPAL RISKS*

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.

Inventories of municipal bonds held by brokers and dealers may decrease, which would lessen their ability to make a market in these securities. Such a reduction in market making capacity could potentially decrease a Trust’s ability to buy or sell bonds. As a result, a Trust may sell a security at a lower price, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative impact on performance. If a Trust needed to sell large blocks of bonds, those sales could further reduce the bonds’ prices and impact performance.

In the normal course of business, certain Trusts invest in securities or other instruments and may enter into certain transactions, and such activities subject each Trust to various risks, including among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate and price fluctuations. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on each Trust and its investments.

Each Trust may be exposed to prepayment risk, which is the risk that borrowers may exercise their option to prepay principal earlier than scheduled during periods of declining interest rates, which would force each Trust to reinvest in lower yielding securities. Each Trust may also be exposed to reinvestment risk, which is the risk that


NOTES TO FINANCIAL STATEMENTS			55

Notes to Financial Statements (unaudited) (continued)

income from each Trust’s portfolio will decline if each Trust invests the proceeds from matured, traded or called fixed-income securities at market interest rates that are below each Trust portfolio’s current earnings rate.

The Trusts 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 Trusts 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 Trust.

There is no assurance that BTT will achieve its investment objectives, including its investment objective of returning $25.00 per share. As BTT approaches its scheduled termination date, it is expected that the maturity of BTT’s portfolio securities will shorten, which is likely to reduce BTT’s income and distributions to shareholders.

A Trust structures and “sponsors” the TOB Trusts in which it holds TOB Residuals and has certain duties and responsibilities, which may give rise to certain additional risks including, but not limited to, compliance, securities law and operational risks.

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

The SEC and various federal banking and housing agencies have adopted credit risk retention rules for securitizations (the “Risk Retention Rules”). The Risk Retention Rules would require the sponsor of a TOB Trust to retain at least 5% of the credit risk of the underlying assets supporting the TOB Trust’s municipal bonds. The Risk Retention Rules may adversely affect the Trusts’ ability to engage in TOB Trust transactions or increase the costs of such transactions in certain circumstances.

TOB Trusts constitute an important component of the municipal bond market. Any modifications or changes to rules governing TOB Trusts may adversely impact the municipal market and the Trusts, including through reduced demand for and liquidity of municipal bonds and increased financing costs for municipal issuers. The ultimate impact of any potential modifications on the TOB Trust market and the overall municipal market is not yet certain.

Each Trust may invest without limitation in illiquid or less liquid investments or investments in which no secondary market is readily available or which are otherwise illiquid, including private placement securities. A Trust may not be able to readily dispose of such investments at prices that approximate those at which the Trust could sell such investments if they were more widely traded and, as a result of such illiquidity, the Trust may have to sell other investments or engage in borrowing transactions if necessary to raise funds to meet its obligations. Limited liquidity can also affect the market price of investments, thereby adversely affecting a Trust’s net asset value and ability to make dividend distributions. Privately issued debt securities are often of below investment grade quality, frequently are unrated and present many of the same risks as investing in below investment grade public debt securities.

A recent outbreak of respiratory disease caused by a novel coronavirus was first detected in China in December 2019 and has now been detected internationally. This coronavirus has resulted in closing borders, quarantines, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of epidemics and pandemics such as the coronavirus, could affect the economies of many nations, individual companies and the market in general in ways that cannot necessarily be foreseen at the present time. The impact of the outbreak may be short term or may last for an extended period of time.

Counterparty Credit Risk: The Trusts may be exposed to counterparty credit risk, or the risk that an entity may fail to or be unable to perform on its commitments related to unsettled or open transactions. The Trusts manage counterparty credit risk by entering into transactions only with counterparties that the Manager believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Trusts to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Trusts’ exposure to market, issuer and counterparty credit risks with respect to these financial assets is approximately their value recorded in the Statements of Assets and Liabilities, less any collateral held by the Trusts.

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 Trusts 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 Trust 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). Additionally, credit risk exists in exchange-traded futures and centrally cleared swaps 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 Trusts.

Concentration Risk: BFZ and BNY invests a substantial amount of their assets in issuers located in a single state or limited number of states. This may subject each Trust to the risk that economic, political or social issues impacting a particular state or group of states could have an adverse and disproportionate impact on the income from, or the value or liquidity of, the Trusts’ respective portfolios. Investment percentages in specific states or U.S. territories are presented in the Schedules of Investments.

As of period end, BFZ invested a significant portion of its assets in securities in the county, city, special district and school district sector. Changes in economic conditions affecting such sector would have a greater impact on the Trusts and could affect the value, income and/or liquidity of positions in such securities.

The Trusts invest a significant portion of their assets in fixed-income securities and/or use derivatives tied to the fixed-income markets. Changes in market interest rates or economic conditions 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 Trusts may be subject to a greater risk of rising interest rates due to the current period of historically low rates.

CAPITAL SHARE TRANSACTIONS

Each Trust is authorized to issue an unlimited number of shares, all of which were initially classified as Common Shares. The par value for each Trust’s Common Shares is $0.10. The par value for each Trust’s Preferred Shares outstanding is $0.10. The Board is authorized, however, to reclassify any unissued Common Shares to Preferred Shares without the approval of Common Shareholders.

Common Shares

For the periods shown, shares issued and outstanding increased by the following amounts as a result of dividend reinvestment:


	BBF
Six Months Ended January 31, 2020		1,507
Year Ended July 31, 2019		4,609

For the six months ended January 31, 2020 and year ended July 31, 2019, shares issued and outstanding remained constant for BFZ, BTT and BNY.

BFZ, BBF and BNY participate in an open market share repurchase program (the “Repurchase Program”). From December 1, 2018 through November 30, 2019, each of BFZ, BBF and BNY may repurchase up to 5% of its outstanding common shares under the Repurchase Program, based on common shares outstanding as of the close of business on November 30, 2018, subject to certain conditions. From December 1, 2019 through November 30, 2020, each of BFZ, BBF and BNY may repurchase up to 5% of its outstanding common shares under the Repurchase Program, based on common shares outstanding as of the close of business on November 30, 2019, subject to certain conditions. There is no assurance that each Trust will purchase shares in any particular amounts. For the six months ended January 31, 2020, BFZ, BBF and BNY did not repurchase any shares.

Preferred Shares

A Trust’s Preferred Shares rank prior to its Common Shares as to the payment of dividends by the Trust and distribution of assets upon dissolution or liquidation of the Trust. The 1940 Act prohibits the declaration of any dividend on Common Shares or the repurchase of Common Shares if the Trust fails to maintain asset coverage of at least 200% of the liquidation preference of the its outstanding Preferred Shares. In addition, pursuant to the Preferred Shares’ governing instruments, a Trust is restricted from declaring and paying dividends on classes of shares ranking junior to or on parity with its Preferred Shares or repurchasing such shares if the Trust fails to declare and pay dividends on the Preferred Shares, redeem any Preferred Shares required to be redeemed under the Preferred Shares’ governing instruments or comply with the basic maintenance amount requirement of the ratings agencies rating the Preferred Shares.

Holders of Preferred Shares have voting rights equal to the voting rights of holders of Common Shares (one vote per share) and vote together with holders of Common Shares (one vote per share) as a single class on certain matters. Holders of Preferred Shares, voting as a separate class, are also entitled to (i) elect two members of the Board, (ii) elect the full Board if dividends on the Preferred Shares are not paid for a period of two years and (iii) a separate class vote to amend the Preferred Share governing documents. In addition, the 1940 Act requires the approval of the holders of a majority of any outstanding Preferred Shares, voting as a separate class, to (a) adopt any plan of reorganization that would adversely affect the Preferred Shares, (b) change a Trust’s sub-classification as a closed-end investment company or change its fundamental investment restrictions or (c) change its business so as to cease to be an investment company.

VRDP Shares

BBF has issued Series W-7 VRDP Shares, $100,000 liquidation preference per share, in one or more privately negotiated offerings to qualified institutional buyers as defined pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The VRDP Shares include a liquidity feature and may be subject to a special rate period. As of period end, the VRDP Shares outstanding were as follows:

Redemption Terms: BBF is required to redeem its VRDP Shares on the maturity date, unless earlier redeemed or repurchased. Six months prior to the maturity date, BBF is required to begin to segregate liquid assets with the Trust’s custodian to fund the redemption. In addition, BBF is required to redeem certain of its outstanding VRDP Shares if it fails to comply with certain asset coverage, basic maintenance amount or leverage requirements.

Subject to certain conditions, the VRDP Shares may also be redeemed, in whole or in part, at any time at the option of BBF. The redemption price per VRDP Share is equal to the liquidation preference per share plus any outstanding unpaid dividends.

Liquidity Feature: VRDP Shares are subject to a fee agreement between the VRDP Trust and the liquidity provider that requires a per annum liquidity fee and, in some cases, an upfront or initial commitment fee, payable to the liquidity provider. These fees, if applicable, are shown as liquidity fees in the Statements of Operations. As of period end, the fee agreement is set to expire, unless renewed or terminated in advance, as follows:


	BBF
Expiration Date		04/15/20


NOTES TO FINANCIAL STATEMENTS			57

Notes to Financial Statements (unaudited) (continued)

The VRDP Shares are also subject to a purchase agreement in connection with the liquidity feature. In the event a purchase agreement is not renewed or is terminated in advance, and VRDP Shares do not become subject to a purchase agreement with an alternate liquidity provider, the VRDP Shares will be subject to mandatory purchase by the liquidity provider prior to the termination of the purchase agreement. In the event of such mandatory purchase, BBF is required to redeem the VRDP Shares six months after the purchase date. Immediately after such mandatory purchase, the VRDP Trust is required to begin to segregate liquid assets with its custodian to fund the redemption. There is no assurance BBF will replace such redeemed VRDP Shares with any other preferred shares or other form of leverage.

Remarketing: BBF may incur remarketing fees on the aggregate principal amount of all its VRDP Shares, which, if any, are included in remarketing fees on Preferred Shares in the Statements of Operations. During any special rate period (as described below), BBF may incur nominal or no remarketing fees.

Ratings: As of period end, the VRDP Shares were assigned the following long-term ratings:


	Moody’s		Fitch
BBF . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .		Aa1		AAA

Special Rate Period: BBF may commence a “special rate period” with respect to its VRDP Shares, during which the VRDP Shares will not be subject to any remarketing and the dividend rate will be based on a predetermined methodology. During a special rate period, short-term ratings on VRDP Shares are withdrawn. BBF’s special rate period has commenced on October 22, 2015 and has a current expiration date of April 15, 2020.

Prior to the expiration date, the VRDP Trust and the VRDP Shares holder may mutually agree to extend the special rate period. If a special rate period is not extended, the VRDP Shares will revert to remarketable securities upon the termination of the special rate period and will be remarketed and available for purchase by qualified institutional investors.

During the special rate period: (i) the liquidity and fee agreements remain in effect, (ii) VRDP Shares remain subject to mandatory redemption by the VRDP Trust on the maturity date, (iii) VRDP Shares will not be remarketed or subject to optional or mandatory tender events, (iv) the VRDP Trust is required to comply with the same asset coverage, basic maintenance amount and leverage requirements for the VRDP Shares as is required when the VRDP Shares are not in a special rate period, (v) the VRDP Trust will pay dividends monthly based on the sum of an agreed upon reference rate and a percentage per annum based on the long-term ratings assigned to the VRDP Shares and (vi) the VRDP Trust will pay nominal or no fees to the liquidity provider and remarketing agent.

If a VRDP Trust redeems its VRDP Shares prior to end of the special rate period and the VRDP Shares have long-term ratings above A1/A+ and its equivalent by all ratings agencies then rating the VRDP Shares, then such redemption may be subject to a redemption premium payable to the holder of the VRDP Shares based on the time remaining in the special rate period, subject to certain exceptions for redemptions that are required to comply with minimum asset coverage requirements.

Dividends: Except during the Special Rate Period as described above, dividends on the VRDP Shares are payable monthly at a variable rate set weekly by the remarketing agent. Such dividend rates are generally based upon a spread over a base rate and cannot exceed a maximum rate. A change in the short-term credit rating of the liquidity provider or the VRDP Shares may adversely affect the dividend rate paid on such shares, although the dividend rate paid on the VRDP Shares is not directly based upon either short-term rating. In the event of a failed remarketing, the dividend rate of the VRDP Shares will be reset to a maximum rate. The maximum rate is determined based on, among other things, the long-term preferred share rating assigned to the VRDP Shares and the length of time that the VRDP Shares fail to be remarketed.

For the six months ended January 31, 2020, the annualized dividend rate for the VRDP Shares was 2.13%.

VMTP Shares

BFZ and BNY (for purposes of this section, the “VMTP Trusts”) have issued Series W-7 VMTP Shares, $100,000 liquidation preference per share, in one or more privately negotiated offerings to qualified institutional buyers as defined pursuant to Rule 144A under the Securities Act The VMTP Shares are subject to certain restrictions on transfer, and VMTP Trusts may also be required to register the VMTP Shares for sale under the Securities Act under certain circumstances. As of period end, the VMTP Shares outstanding and assigned long-term ratings were as follows:

Redemption Terms: Each VMTP Trust is required to redeem its VMTP Shares on the term redemption date, unless earlier redeemed or repurchased or unless extended. There is no assurance that a term will be extended further or that any VMTP Shares will be replaced with any other preferred shares or other form of leverage upon the redemption or repurchase of the VMTP Shares. Six months prior to the term redemption date, a VMTP Trust is required to begin to segregate liquid assets with its custodian to fund the redemption. In addition, a VMTP Trust is required to redeem certain of its outstanding VMTP Shares if it fails to comply with certain asset coverage, basic maintenance amount or leverage requirements.

Subject to certain conditions, VMTP Shares may be redeemed, in whole or in part, at any time at the option of the VMTP Trust. The redemption price per VMTP Share is equal to the liquidation preference per share plus any outstanding unpaid dividends.


58		2020 BLACKROCK SEMI-ANNUAL REPORT TO SHAREHOLDERS

Notes to Financial Statements (unaudited) (continued)

Dividends: Dividends on the VMTP Shares are declared daily and payable monthly at a variable rate set weekly at a fixed rate spread to the Securities Industry and Financial Markets Association Municipal Swap Index or to a percentage of the one-month LIBOR rate, as set forth in the VMTP Shares governing instrument. The fixed spread is determined based on the long-term preferred share rating assigned to the VMTP Shares by the ratings agencies then rating the VMTP Shares.

The dividend rate on VMTP Shares is subject to a step-up spread if the VMTP Trust fails to comply with certain provisions, including, among other things, the timely payment of dividends, redemptions or gross-up payments, and complying with certain asset coverage and leverage requirements.

For the six months ended January 31, 2020, the average annualized dividend rates for the VMTP Shares were as follows.


	BFZ			BNY

RVMTP Shares

BTT has issued Series W-7 RVMTP Shares, $5,000,000 liquidation preference per share, in privately negotiated offerings to qualified institutional buyers as defined pursuant to Rule 144A under the Securities Act. The RVMTP Shares are subject to certain restrictions on transfer outside of a remarketing. As of period end, the RVMTP Shares outstanding of BTT were as follows:


	Issue Date		Shares Issued		Shares Outstanding		Aggregate Principal		Term Redemption Date
BTT		01/10/2013		50		50	$	250,000,000		12/31/2030
		01/30/2013		50		50		250,000,000		12/31/2030
		02/20/2013		50		50		250,000,000		12/31/2030

Redemption Terms: BTT is required to redeem its RVMTP Shares on the term redemption date or within six months of an unsuccessful remarketing, unless earlier redeemed or repurchased. There is no assurance that RVMTP Shares will be replaced with any other preferred shares or other form of leverage upon the redemption or repurchase of the RVMTP Shares. In addition, BTT is required to redeem certain of its outstanding RVMTP Shares if it fails to comply with certain asset coverage, basic maintenance amount or leverage requirements.

Subject to certain conditions, RVMTP Shares may be redeemed, in whole or in part, at any time at the option of BTT. The redemption price per RVMTP Share is equal to the liquidation preference per share plus any outstanding unpaid dividends. The RVMTP Shares are subject to certain restrictions on transfer outside of a remarketing. The RVMTP Shares are subject to remarketing upon 90 days’ notice by holders of the RVMTP Shares and 30 days’ notice by BTT. Each remarketing must be at least six months apart from the last remarketing. A holder of RVMTP Shares may submit notice of remarketing only if such holder requests a remarketing of at least the lesser of (i) $100,000,000 of RVMTP Shares or (ii) all of the RVMTP Shares held by such holder.

Dividends: Dividends on the RVMTP Shares are declared daily and payable monthly at a variable rate set weekly at a fixed rate spread to a percentage of the one-month LIBOR rate. The fixed rate spread may be adjusted at each remarketing or upon the agreement of BTT and the then-holder(s) of the RVMTP Shares. In the event that all of the RVMTP Shares submitted for remarketing are not successfully remarketed, a failed remarketing would occur, and all holders would retain their RVMTP Shares. In the event of a failed remarketing, the fixed rate spread would be set at the fixed rate spread applicable to such failed remarketing. BTT has the right to reject any fixed spread determined at a remarketing, and such rejection would result in a failed remarketing and the fixed rate spread would be set at the fixed rate spread applicable to such failed remarketing. The fixed rate spread applicable due to a failed remarketing depends on whether the remarketing was pursuant to a mandatory or non-mandatory tender. In the case of a failed remarketing following a mandatory tender, the failed remarketing spread would be the sum of the last applicable spread in effect immediately prior to the failed remarketing date for such failed remarketing plus 0.75%. In the case of a failed remarketing not associated with a mandatory tender, the failed remarketing spread would be the sum of the last applicable spread in effect immediately prior to the failed remarketing date for such failed remarketing plus 0.25%.

For the six months ended January 31, 2019, the average annualized dividend rate for the RVMTP Shares was 2.01%.

Remarketing: In the event of a failed remarketing that is not subsequently cured, BTT will be required to redeem the RVMTP Shares subject to such failed remarketing on a date that is approximately six months from the remarketing date for such failed remarketing, provided that no redemption of any RVMTP Share may occur within one year of the date of issuance of such RVMTP Share. At the date of issuance and as of period end, the RVMTP Shares were assigned long-term ratings of Aa1 from Moody’s and AAA from Fitch. The dividend rate on the RVMTP Shares is subject to a step-up spread if BTT fails to comply with certain provisions, including, among other things, the timely payment of dividends, redemptions or gross-up payments, and complying with certain asset coverage and leverage requirements.

During the six months ended January 31, 2020, no RVMTP Shares were tendered for remarketing.

For the six months ended January 31, 2020, RVMTP Shares issued and outstanding of BTT remained constant.

Offering Costs: The Trusts incurred costs in connection with the issuance of VRDP, VMTP and RVMTP Shares, which were recorded as a direct deduction from the carrying value of the related debt liability and will be amortized over the life of the VRDP, VMTP and RVMTP Shares with the exception of upfront fees paid by BBF to the liquidity provider which, if any, were amortized over the life of the liquidity agreement. Amortization of these costs is included in interest expense, fees and amortization of offering costs in the Statements of Operations.

Financial Reporting: The VRDP, VMTP and RVMTP Shares are considered debt of the issuer; therefore, the liquidation preference, which approximates fair value of the VRDP, VMTP and RVMTP Shares, is recorded as a liability in the Statements of Assets and Liabilities net of deferred offering costs. Unpaid dividends are included in

interest expense and fees payable in the Statements of Assets and Liabilities, and the dividends accrued and paid on the VRDP, VMTP and RVMTP Shares are included as a component of interest expense, fees and amortization of offering costs in the Statements of Operations. The VRDP, VMTP and RVMTP Shares are treated as equity for tax purposes. Dividends paid to holders of the VRDP, VMTP and RVMTP Shares are generally classified as tax-exempt income for tax-reporting purposes. Dividends and amortization of deferred offering costs on VRDP, VMTP and RVMTP Shares are included in interest expense, fees and amortization of offering costs in the Statements of Operations.

Additional Information

Section 19(a) Notices

The amounts and sources of distributions reported are estimates and are being provided pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon each Trust’s investment experience during the year and may be subject to changes based on tax regulations. Shareholders will receive a Form 1099-DIV each calendar year that will inform them how to report these distributions for federal income tax purposes.

^(a)

The Trust estimates that it has distributed more than its net investment income and net realized capital gains; therefore, a portion of the distribution may be a return of capital. A return of capital may occur, for example, when some or all of the shareholder’s investment in the Trust is returned to the shareholder. A return of capital does not necessarily reflect the Trust’s investment performance and should not be confused with “yield” or “income.” When distributions exceed total return performance, the difference will reduce the Trust’s net asset value per share.

Section 19(a) notices for the Trusts, as applicable, are available on the BlackRock website at blackrock.com.

Trust Certification

The Trusts are listed for trading on the NYSE and have filed with the NYSE their annual chief executive officer certification regarding compliance with the NYSE’s listing standards. The Trusts filed with the SEC the certification of its chief executive officer and chief financial officer required by section 302 of the Sarbanes-Oxley Act.

Dividend Policy

Each Trust’s dividend policy is to distribute all or a portion of its net investment income to its shareholders on a monthly basis. In order to provide shareholders with a more stable level of distributions, the Trusts may at times pay out less than the entire amount of net investment income earned in any particular month and may at times in any particular month pay out such accumulated but undistributed income in addition to net investment income earned in that month. As a result, the distributions paid by the Trusts for any particular month may be more or less than the amount of net investment income earned by the Trusts during such month. The Trusts’ current accumulated but undistributed net investment income, if any, is disclosed as accumulated earnings (loss) in the Statements of Assets and Liabilities, which comprises part of the financial information included in this report.

General Information

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

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

In accordance with Section 23(c) of the Investment Company Act of 1940, each Trust may from time to time purchase shares of its common stock in the open market or in private transactions.

Quarterly performance, semi-annual and annual reports, current net asset value and other information regarding the Trusts may be found on BlackRock’s website, which can be accessed at blackrock.com.

This practice is commonly called “householding” and is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise.
