Section 19(b) Disclosure

BlackRock Core Bond Trust’s (BHK), BlackRock Corporate High Yield Fund, Inc.’s (HYT), BlackRock Credit Allocation Income Trust’s (BTZ) and BlackRock Floating Rate Income Trust’s (BGT) (collectively the “Trusts”, or individually a “Trust”), acting pursuant to a U.S. Securities and Exchange Commission (“SEC”) exemptive order and with the approval of each Trust’s Board of Trustees or Directors, as applicable (the “Board”), each have adopted a managed distribution plan, consistent with its investment objectives and policies to support a level distribution of income, capital gains and/or return of capital (the “Plan”). In accordance with the Plans, the Trusts currently distribute the following fixed amounts per share on a monthly basis:

The fixed amounts distributed per share are subject to change at the discretion of each Trust’s Board. Under its Plan, each Trust will distribute all available net income to its shareholders as required by the Internal Revenue Code of 1986, as amended (the “Code”). If sufficient income (inclusive of net income and short-term capital gains) is not earned on a monthly basis, the Trusts will distribute long-term capital gains and/or return of capital to shareholders in order to maintain a level distribution. Each monthly distribution to shareholders is expected to be at the fixed amount established by the Board; however, each Trust may make additional distributions from time to time, including additional capital gain distributions at the end of the taxable year, if required to meet requirements imposed by the Code and/or the Investment Company Act of 1940, as amended (the “1940 Act”).

Shareholders should not draw any conclusions about each Trust’s investment performance from the amount of these distributions or from the terms of the Plan. Each Trust’s total return performance is presented in its financial highlights table.

The Board may amend, suspend or terminate a Trust’s Plan at any time without prior notice to the Trust’s shareholders if it deems such actions to be in the best interests of the Trust or its shareholders. The suspension or termination of the Plan could have the effect of creating a trading discount (if the Trust’s stock is trading at or above net asset value) or widening an existing trading discount. The Trusts are subject to risks that could have an adverse impact on their ability to maintain level distributions. Examples of potential risks include, but are not limited to, economic downturns impacting the markets, changes in interest rates, decreased market volatility, companies suspending or decreasing corporate dividend distributions and changes in the Code.

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 each Trust (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, each Trust’s shareholders benefit from the incremental net income. The interest earned on securities purchased with the proceeds from leverage (after paying the leverage costs) 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 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 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 a Trust’s return on assets purchased with leverage proceeds, income to shareholders is lower than if a Trust 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 amount of each Trust’s obligations under its leverage arrangement 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 a Trust’s 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 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 Trust 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 shareholders and may reduce income to the shareholders. Moreover, to the extent the calculation of each Trust’s investment advisory fees includes assets purchased with the proceeds of leverage, the investment advisory fees payable to each Trust’s investment adviser will be higher than if the Trusts did not use leverage.

Each Trust may utilize leverage through a credit facility or reverse repurchase agreements as described in the Notes to Financial Statements, if applicable.

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. 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 its credit facility, 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 a reverse repurchase agreement (including accrued interest) then such transaction 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.

Investment Objective

BlackRock Core Bond Trust’s (BHK) (the “Trust”) investment objective is to provide current income and capital appreciation. The Trust seeks to achieve its investment objective by investing, under normal market conditions, at least 75% of its managed assets in bonds that are investment grade quality at the time of investment. Under normal market conditions, the Trust intends to invest its assets primarily in a diversified portfolio of investment grade bonds, which may include, but are not limited to, corporate bonds, U.S. government and agency securities and mortgage-related securities. The Trust may invest up to 25% of its total managed assets in bonds that at the time of investment are rated Ba/BB or below by Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings, Fitch Ratings (“Fitch”) or another nationally recognized rating agency or bonds that are unrated but judged to be of comparable quality by the investment adviser. The Trust may invest up to 10% of its managed assets in bonds issued in foreign currencies. The Trust may invest directly in such securities or synthetically through the use of derivatives.

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

Market Price and Net Asset Value History for the Past Five Years

Performance results may include adjustments made for financial reporting purposes in accordance with U.S. generally accepted accounting principles. Past performance is not an indication of future results.

BHK is presenting the Reference Benchmark to accompany trust performance. The Reference Benchmark is presented for informational purposes only, as the Trust is actively managed and does not seek to track or replicate the performance of the Reference Benchmark or any other index. The portfolio investments of the Trust may differ substantially from the securities that comprise the indices within the Reference Benchmark, which may cause the Trust’s performance to differ materially from that of the Reference Benchmark. The Trust employs leverage as part of its investment strategy, which may change over time at the discretion of BlackRock Advisors, LLC (the “Manager”) as market and other conditions warrant. In contrast, the Reference Benchmark is not adjusted for leverage. Therefore, leverage generally may result in the Trust outperforming the Reference Benchmark in rising markets and underperforming in declining markets. The Board considers additional factors to evaluate the Trust’s performance, such as the performance of the Trust relative to a peer group of funds, a leverage-adjusted benchmark and/or other information provided by the Manager.

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

What factors influenced performance?

Positive contributions to the Trust’s absolute performance over the period came from its allocations to U.S. high yield corporate credit as well as to securitized assets including commercial mortgage-backed securities (“CMBS”) and asset-backed securities (“ABS”). The use of derivatives (primarily interest rate swaps) and non-U.S. dollar exposures also contributed positively.

The principal detractors from the Trust’s absolute performance included positioning with respect to U.S. Treasuries, as well as exposures to agency collateralized mortgage obligations (“CMOs”) and 30-year passthrough mortgage-backed securities (“MBS”).

Derivatives are utilized by the Trust in order to manage and/or take outright views on interest rates, credit risk and/or foreign exchange positions in the portfolio. During the period, the Trust’s use of derivatives contributed positively to performance.

Describe recent portfolio activity.

Over the reporting period, the Trust increased exposure to investment grade corporate bonds, U.S. Treasuries, high yield corporate bonds and 30-year MBS. The Trust trimmed exposure to CMBS and increased its short position in U.S. municipal bonds.

Describe portfolio positioning at period end.

At period end, the Trust maintained a diversified exposure within non-government spread sectors, including investment grade corporate credit, high yield corporate credit, CMBS, ABS and emerging market debt. The Trust also held exposure to government-related sectors such as 30-year MBS passthroughs, agency CMOs and U.S. agency securities.

Investment Objective

BlackRock Corporate High Yield Fund, Inc.’s (HYT) (the “Trust”) primary investment objective is to provide shareholders with current income. The Trust’s secondary investment objective is to provide shareholders with capital appreciation. The Trust seeks to achieve its objectives by investing primarily in a diversified portfolio of fixed income securities which are rated at the time of investment to be below investment grade or, if unrated, are considered by the investment adviser to be of comparable quality. The Trust may invest directly in fixed income securities or synthetically through the use of derivatives.

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

Performance results may include adjustments made for financial reporting purposes in accordance with U.S. generally accepted accounting principles. Past performance is not an indication of future results.

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

What factors influenced performance?

High-yield bonds delivered positive returns and outpaced the investment-grade bond market in the first half of the period. The gains were driven by the combination of a strong economic recovery, rising oil prices, and continued support from fiscal and monetary policy. Together, these factors helped fuel investors’ appetite for both risk and yield.

At the sector level, positions in the independent energy, technology and health care sectors contributed to Trust performance. By credit rating, B and BB rated debt made the largest contributions. The Trust’s tactical allocations to equities and floating rate loan interest (“bank loans”) also helped absolute returns.

The Fund’s allocations to the electric utilities, railroads and natural gas sectors slightly detracted from relative performance. From a credit quality perspective, BBB rated bonds were a minor detractor.

Describe recent portfolio activity.

While the Trust’s key positioning themes remained broadly consistent, the investment adviser used tactical sector- and issuer-level positions to take advantage of market opportunities. The investment manager reduced the portfolio’s allocation to investment-grade bonds during the first half of 2021, ending the period with a weighting of approximately 4% in this area. The remaining position largely represented issuer-specific opportunities. The Trust continued to use derivatives, such as total return swaps and credit default swaps, in order to manage its positioning.

The Trust slightly increased its allocation to bank loans during the period. It increased its allocation to the technology, airlines and retailers sectors, while reducing its weighting in the banking, automotive and midstream energy sectors. The investment adviser saw an opportunity in sectors most sensitive to the re-opening of the economy—including transportation, leisure, lodging and gaming—on the belief these areas will benefit from the ongoing recovery and widespread distribution of the COVID-19 vaccine.

Describe portfolio positioning at period end.

The Trust was underweight in BB rated issues and overweight in select CCCs. It maintained an underweight in the highest-yielding portion of the market with the largest concentration of distressed assets.

The Trust also continued to hold a tactical allocation of about 19% to bank loans, which the investment adviser believed offered an attractive value versus high-yield bonds. These senior-secured assets experienced a recovery similar to high yield, but yield spreads remain wide versus historical levels. The Trust also held an out-of-benchmark allocation to equities of approximately 4%. The top sector overweight positions included technology, cable/satellite and aerospace/defense, while food & beverage, finance companies and electric utilities were the largest underweights.

Investment Objective

BlackRock Credit Allocation Income Trust’s (BTZ) (the “Trust”) investment objective is to provide current income, current gains and capital appreciation. The Trust seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in credit-related securities, including, but not limited to, investment grade corporate bonds, high yield bonds (commonly referred to as “junk” bonds), bank loans, preferred securities or convertible bonds or derivatives with economic characteristics similar to these credit-related securities. The Trust may invest directly in such 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:

What factors influenced performance?

Positive contributors to the Trust’s performance included exposure to U.S. high yield corporate bonds and collateralized loan obligations (“CLOs”). The Trust’s allocation to capital securities also aided performance. Finally, exposure to European high yield corporate bonds contributed to the Trust’s return.

Detractors from performance included exposure to emerging market debt, as rising U.S. Treasury yields weighed on the category. In a similar vein, the Trust’s exposure to duration (and corresponding interest rate sensitivity) detracted given the move higher in Treasury yields.

In addition to employing leverage, the Trust uses derivatives as part of its investment strategy, including forward contracts to manage foreign currency exposure of non-U.S. positions back to U.S. dollars and interest rate futures to adjust duration positioning tactically as needed. The use of derivatives over the period did not have a material impact on performance.

Describe recent portfolio activity.

Over the period, the Trust reduced exposure to U.S. investment grade corporate bonds, capital securities, and CLOs, while increasing exposure to U.S. high yield corporate bonds. The Trust’s use of leverage over the period had a positive impact on performance.

Describe portfolio positioning at period end.

At period end, the Trust was positioned for economic growth to be supported by continued easing of lockdowns and resumption of business activities, along with an awareness that valuations are full and a range of risks, including inflation, bear watching. With this backdrop, the Trust maintained core allocations to U.S. high yield and investment grade corporate bonds as well as capital securities, with exposure to CLOs and non-U.S. credit markets as well.

Investment Objective

BlackRock Floating Rate Income Trust’s (BGT) (the “Trust”) primary investment objective is to provide a high level of current income. The Trust’s secondary investment objective is to seek the preservation of capital to the extent consistent with its primary objective of high current income. The Trust seeks to achieve its investment objectives by investing primarily, under normal conditions, at least 80% of its assets in floating and variable rate instruments of U.S. and non-U.S. issuers, including a substantial portion of its assets in global floating and variable rate securities including senior secured floating rate loans made to corporate and other business entities. Under normal market conditions, the Trust expects that the average effective duration of its portfolio will be no more than 1.5 years. The Trust may invest directly in such 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:

What factors influenced performance?

Floating rate loan interest (“bank loans”)performed well in the first half of the period. In addition to benefiting from the tailwind of improving economic growth, concerns that the Fed may need to begin raising interest rates led to higher demand for floating rate assets.

From an asset allocation perspective, the Trust’s core exposure to bank loans and tactical allocations to high yield bonds, equities and investment-grade corporate bonds contributed to performance. From a sector perspective, the largest contributors included technology, airlines and health care. With respect to credit tiers, the Trust’s positions in B rated debt made the largest contribution to absolute returns, followed by CCCs and BBs. There were no significant detractors from absolute performance given the positive performance for the bank loan market.

Describe recent portfolio activity.

The investment adviser marginally reduced the Trust’s allocation to investment-grade bonds in favor of bank loans due to supportive supply-and-demand conditions and attractive relative values. The investment adviser’s credit rating views remained consistent over the past several quarters, with a focus on avoiding the more volatile stressed CCC category. The investment adviser tactically managed the Trust’s sector positioning, although it placed a greater focus on individual security selection later in the period. The Trust continued to use liquid, index-based derivatives in the loan and high-yield markets inorder to manage its positioning.

Describe portfolio positioning at period end.

The Trust remained predominately invested in bank loans, with the rest of the portfolio primarily invested in high yield bonds. By credit rating, B rated loans were the Trust’s largest position, and it had a much smaller weightings in the higher-risk CCC rated segment. Within the single B category, the investment adviser remained focused on higher-quality B+ and B rated debt, with less of an emphasis on securities rated B-.

The investment adviser’s core sector views stayed largely intact. Some of the Trust’s top sector positions were technology companies, particularly in the enterprise software area. Health care, consumer cyclical services and building materials were also areas where the investment adviser identified compelling risk-reward opportunities. The investment adviser maintained a lower allocation to energy and the consumer cyclical sectors, such as retailers and leisure, on the belief that these market segments continued to face significant headwinds.

The Trust had a bias toward larger loan tranches of $1 billion and above. The investment adviser maintained a preference for loan/bond capital structures over the loan-only segment. The securities that Trust did own in the latter category were typically transactions of $1 billion or more. The Trust remained underweight in the 2017 and 2018 vintages, arguably a period with more aggressive lending standards and weaker protections for loan holders.
