Section 19(a) Notices

BlackRock 2022 Global Income Opportunity Trusts (BGIO) and BlackRock Income Trust, Inc.s (BKT) (collectively the Trusts, or individually a Trust) 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 Trusts 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) Each Trust estimates that it has distributed more than its net 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 shareholders investment in a Trust is returned to the shareholder. A return of capital does not necessarily reflect a Trusts investment performance and should not be confused with yield or income. When distributions exceed total return performance, the difference will reduce a Trusts net asset value per share.

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

Managed Distribution Plan

BKT, with the approval of BKTs Board of Directors (the Board), 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 Plan, BKT currently distributes a fixed amount of $.0344 per share on a monthly basis.

The fixed amount distributed per share is subject to change at the discretion of the Board. BKT is currently not relying on any exemptive relief from Section 19(b) of the Investment Company Act of 1940, as amended (the 1940 Act). Under its Plan, BKT will distribute all available investment income to its shareholders as required by the Internal Revenue Code of 1986, as amended (the Code). If sufficient income (inclusive of net investment income and short-term capital gains) is not earned on a monthly basis, BKT 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, BKT 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 1940 Act.

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

The Board may amend, suspend or terminate the Plan at any time without prior notice to BKTs shareholders if it deems such actions to be in the best interests of BKT or its shareholders. The suspension or termination of the Plan could have the effect of creating a trading discount (if BKTs stock is trading at or above net asset value) or widening an existing trading discount. BKT is subject to risks that could have an adverse impact on its 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 Markets in Review

Dear Shareholder,

The 12-month reporting period as of June 30, 2021 was a remarkable period of adaptation and recovery, as the global economy dealt with the implications of the coronavirus (or COVID-19) pandemic. The United States, along with most of the world, began the reporting period emerging from a severe recession, prompted by pandemic-related restrictions that disrupted many aspects of daily life. However, easing restrictions and robust government intervention led to a strong rebound, and the economy grew at a significant pace for the reporting period, recovering much of the output lost at the beginning of the pandemic.

Equity prices rose with the broader economy, as investors became increasingly optimistic about the economic outlook. Stocks rose through the summer of 2020, fed by strong fiscal and monetary support and positive economic indicators. The implementation of mass vaccination campaigns and passage of an additional $1.9 trillion of fiscal stimulus further boosted stocks, and many equity indices neared or surpassed all-time highs late in the reporting period. In the United States, both large- and small-capitalization stocks posted a significant advance. International equities also gained, as both developed countries and emerging markets rebounded substantially.

The 10-year U.S. Treasury yield (which is inversely related to bond prices) had fallen sharply prior to the beginning of the reporting period, which meant bonds were priced for extreme risk avoidance and economic disruption. Despite expectations of doom and gloom, the economy expanded rapidly, stoking inflation concerns in early 2021, which led to higher yields and a negative overall return for most U.S. Treasuries. In the corporate bond market, support from the U.S. Federal Reserve (the Fed) assuaged credit concerns and led to substantial returns for high-yield corporate bonds, although investment-grade corporates declined slightly.

The Fed remained committed to accommodative monetary policy by maintaining near zero interest rates and by reiterating that inflation could exceed its 2% target for a sustained period without triggering a rate increase. Late in the period the Fed elaborated on their expected timeline, raising the likelihood of slower bond purchasing and the possibility of higher rates in 2023.

Looking ahead, while coronavirus-related disruptions have clearly hindered worldwide economic growth, we believe that the global expansion will continue to accelerate as vaccination efforts ramp up and pent-up consumer demand leads to higher spending. While we expect inflation to increase somewhat as the expansion continues, we believe the recent uptick owes more to temporary supply disruptions than a lasting change in fundamentals. The change in Fed policy also means that moderate inflation is less likely to be followed by interest rate hikes that could threaten the economic expansion.

Overall, we favor a moderately positive stance toward risk, with an overweight in equities. Sectors that are better poised to manage the transition to a lower-carbon world, such as technology and healthcare, are particularly attractive in the long-term. U.S. small-caps and European equities are likely to benefit from the continuing vaccine-led restart. We are underweight long-term on credit, but inflation-protected U.S. Treasuries, Asian fixed income, and Chinese government bonds offer potential opportunities. We believe that international diversification and a focus on sustainability can help provide portfolio resilience, and the disruption created by the coronavirus appears to be accelerating the shift toward sustainable investments.

In this environment, our view is that 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 todays markets.

Sincerely,

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 Trusts 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 Trusts 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 Trusts 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 Trusts financing cost of leverage is significantly lower than the income earned on a Trusts 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 Trusts 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 Trusts 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 Trusts intended leveraging strategy will be successful.

The use of leverage also generally causes greater changes in each Trusts 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 Trusts 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 Trusts 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 Trusts investment advisory fees includes assets purchased with the proceeds of leverage, the investment advisory fees payable to each Trusts investment adviser will be higher than if the Trusts did not use leverage.

Each Trust may utilize leverage through 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.

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 Trusts 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 advisers 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 June 30, 2021 BlackRock 2022 Global Income Opportunity Trust (BGIO)

Investment Objective

BlackRock 2022 Global Income Opportunity Trusts (BGIO) (the Trust) investment objective is to seek to distribute a high level of current income and to earn a total return, based on the net asset value of the Trusts common shares of beneficial interest, that exceeds the return on the Bloomberg Barclays 1-3 Month U.S. Treasury Bill Index by 500 basis points (or 5.00%) on an annualized basis over the life of the Trust, under normal market conditions. The Trust will terminate on or about February 28, 2022.

No assurance can be given that the Trusts investment objective will be achieved. Risks relating to the Trusts investment objective are described in further detail in the Notes to Financial Statements.

On June 9, 2021, the Board approved the adoption of a Plan of Liquidation in accordance with BGIOs strategy of terminating on or before February 28, 2022. Under the Plan of Liquidation which was effective on June 30, 2021, BGIO will begin the process of liquidating portfolio assets and unwinding its affairs. The Trust expects to make periodic liquidating distributions to shareholders pursuant to the Plan of Liquidation in advance of its termination and make a final liquidating distribution on or around December 31, 2021.

The Trusts investment objective is, in part, to earn a total return that exceeds the return on the Bloomberg Barclays 1-3 Month U.S. Treasury Bill Index (the Index) by 500 basis points (or 5.00%) on an annualized basis over the life of the Trust, under normal market conditions. The Trusts investment policies do not contemplate any meaningful amount of investment in securities that comprise the Index under normal market conditions; rather, the Trust uses the Index as a proxy for a risk-free rate of return that its investment objective seeks to exceed. Because the achievement of the Trusts investment objective is measured on an annualized basis over the life of the Trust, the Trusts performance may be more or less than the spread over the Index contained in the Trusts investment objective during individual annual periods or for any period of time shorter than the life of the Trust. The Board considers certain factors to evaluate the Trusts performance, such as the performance of the Trust relative to its investment objective and/or other information provided by BlackRock Advisors, LLC (the Manager).

More information about the Trusts historical performance can be found in the Closed End Funds section of blackrock.com.

The following discussion relates to the Trusts absolute performance based on NAV:

What factors influenced performance?

Over the period, the largest contributors to the Trusts performance were exposures to securitized assets, including collateralized loan obligations (CLOs), commercial mortgage-backed securities (CMBS) and non-agency residential mortgage-backed securities (RMBS). Allocations to high yield corporate credit and emerging market debt also added to performance.

The Trusts stance with respect to duration (and corresponding interest rate sensitivity) detracted slightly from performance over the period.

Describe recent portfolio activity.

As the Trust entered the final year of its term, the investment adviser actively sought opportunities to wind down the portfolio. Over the period, the Trust primarily reduced exposures in U.S. high yield corporate credit and emerging market debt, in names where valuations were relatively high. The Trust also marginally reduced positions in CMBS and CLOs while remaining constructive regarding these sectors. In addition, the Trust continued to trim duration given diminished hedging benefit from domestic rates exposure.

The Trust used derivatives primarily in the form of Treasury futures during the period to manage duration and yield curve exposure. The Trusts use of derivatives had a negative impact on Trust performance.

Describe portfolio positioning at period end.

At the end of the period, the Trust continued to maintain diversified exposure across fixed income sectors, including emerging market securities, CMBS, RMBS, CLOs and high yield corporate bonds. As of June 30, 2021, the Trusts portfolio had an effective duration of one year, with all-in yields around 3.8%.

As a result of the Trusts liquidation plan, the portfolio ended the period with a cash position of 12%. The Funds cash position had no material impact on Fund performance for the period.

(c) This unmanaged index (formerly known as Citigroup Mortgage Index) (the Reference Benchmark) includes all outstanding government sponsored fixed rate mortgage-backed securities, weighted in proportion to their current market capitalization.

BKT 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 Trusts 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 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 Trusts 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.

More information about the Trusts historical performance can be found in the Closed End Funds section of blackrock.com.

The following discussion relates to the Trusts absolute performance based on NAV:

What factors influenced performance?

The largest contributor to the Trusts return during the six-month period came from its heavy allocation to well-structured agency collateralized mortgage obligations (CMOs). The portfolios allocation to conventional pass-through agency MBS also contributed to Trust performance. More specifically, the funds selection of call-protected specified pools outperformed generic seasoned collateral in the high coupon cohorts. Trust performance also benefited from its modest allocation to agency commercial mortgage-backed security (CMBS) interest-only exposures, which served to enhance income.

The largest detractors from the Trusts return included its allocation to agency MBS derivatives including interest-only and inverse interest-only positions, which experienced a widening in risk premia in the second quarter of 2021. The Trusts positioning on the MBS coupon stack also detracted from overall return, where its relative overweight to higher coupon MBS lagged the performance of lower coupons year-to-date.

The Trust held derivatives during the period as a part of its investment strategy. Derivatives are utilized by the Trust in order to manage risk and/or take outright views on interest rates in the portfolio. In particular, the portfolio employed Treasury futures and interest rate swaps to manage duration and yield curve bias. The Trusts interest rate derivatives positions contributed positively to performance during the six-month period.

Describe recent portfolio activity.

During the six-month period, the trust marginally increased its allocation to agency CMOs, agency MBS derivatives, and agency CMBS interest-only securities. The trust also increased its exposure to lower coupon MBS in the form of to-be-announced securities (TBAs).

Describe portfolio positioning at period end.

The Trust continues to maintain an overweight in well-structured agency CMOs and agency MBS interest-only derivatives, with a focus on structures collateralized by call protected and seasoned collateral that demonstrates more favorable prepayment characteristics. Within its allocation to agency MBS pass-throughs, the Trust holds an overweight in higher coupon MBS, motivated by higher income and an outlook for prepayment speed fatigue on the higher coupon borrower set. The Trust also holds exposure to lower coupon MBS as a hedge against prepayment risk, primarily in the form of TBAs. The Trust is positioned marginally long convexity (i.e., the rate at which duration changes in response to interest rate movements) relative to the benchmark, primarily through its allocation to agency CMOs and call-protected specified pools.

The Trust held only marginal positions in other securitized assets such as legacy (pre-financial crisis) non-agency residential MBS and CMBS, preferring to isolate prepayment and structural characteristics in higher quality agency-backed assets rather than seek credit exposure.

Net change in unrealized appreciation (depreciation) on investments still held at June 30, 2021 (b)	$ 975	$ (94,972	)	$ 430,635	$	22,215	$	6,349	$	365,202

(a) Included in the related net change in unrealized appreciation (depreciation) in the Statements of Operations.

(b) Any difference between net change in unrealized appreciation (depreciation) and net change in unrealized appreciation (depreciation) on investments still held at June 30, 2021 is generally due to investments no longer held or categorized as Level 3 at period end.

The following table summarizes the valuation approaches used and unobservable inputs utilized by the BlackRock Global Valuation Methodologies Committee (the Global Valuation Committee) to determine the value of certain of the Trusts Level 3 financial instruments as of period end. The table does not include Level 3 financial instruments with values based upon unadjusted third party pricing information in the amount of $1,516,640. A significant change in third party information could result in a significantly lower or higher value of such Level 3 financial instruments.

	Value
Assets
Common Stocks	$ 23,384	Market	EBITDA Multiple	3.50x
Corporate Bonds	2,300,767	Income	Discount Rate	4% - 11%	10 %
		Market	EBITDA Multiple	3.50x
	$ 2,324,151

(a) A significant change in unobservable input would have resulted in a correlated (inverse) significant change to value.

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 — BlackRock 2022 Global Income Opportunity Trust	BGIO	Delaware	Diversified
BlackRock Income Trust, Inc.	BKT	Maryland	Diversified

The Board of Directors of BKT and Board of Trustees of BGIO are collectively referred to throughout this report as the Board, and the directors/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.

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 (the trade dates). Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions, if any, are recorded on the ex-dividend dates. Non-cash dividends, if any, are recorded on the ex-dividend dates at fair value. Dividends from foreign securities where the ex-dividend dates may have passed are subsequently recorded when the Trusts are informed of the ex-dividend dates. Under the applicable foreign tax laws, a withholding tax at various rates may be imposed on capital gains, dividends and interest. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on an accrual basis. For convertible securities, premiums attributable to the debt instrument are amortized, but premiums attributable to the conversion feature are not amortized.

Foreign Currency Translation: Each Trusts books and records are maintained in U.S. dollars. Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates determined as of the close of trading on the New York Stock Exchange (NYSE). Purchases and sales of investments are recorded at the rates of exchange prevailing on the respective dates of such transactions. Generally, when the U.S. dollar rises in value against a foreign currency, the investments denominated in that currency will lose value; the opposite effect occurs if the U.S. dollar falls in relative value.

Each Trust does not isolate the effect of fluctuations in foreign exchange rates from the effect of fluctuations in the market prices of investments for financial reporting purposes. Accordingly, the effects of changes in exchange rates on investments are not segregated in the Statements of Operations from the effects of changes in market prices of those investments, but are included as a component of net realized and unrealized gain (loss) from investments. Each Trust reports realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are generally treated as ordinary income for U.S. federal income tax purposes.

Segregation and Collateralization: In cases where a Trust enters into certain investments (e.g., dollar rolls, TBA sale commitments, futures contracts, forward foreign currency exchange contracts, options written, swaps and short sales) or certain borrowings (e.g., reverse repurchase 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: For BGIO, distributions from net investment income are declared monthly and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates and made at least annually. Distributions paid by BKT are recorded on the ex-dividend dates. Subject to BKTs managed distribution plan, BKT intends to make monthly cash distributions to shareholders, which may consist of net investment income and net realized and unrealized gains on investments and/or return of capital.

BGIO expects to make periodic liquidating distributions to shareholders pursuant to the Plan of Liquidation in advance of its termination and make a final liquidating distribution on or around December 31, 2021.

N O T E S T O F I N A N C I A L S T A T E M E N T S 43

Notes to Financial Statements (unaudited) (continued)

The character of distributions is determined in accordance with U.S. federal income tax regulations, which may differ from U.S. GAAP. The portion of distributions that exceeds a Trusts current and accumulated earnings and profits, which are measured on a tax basis, will constitute a non-taxable return of capital.

Deferred Compensation Plan: Under the Deferred Compensation Plan (the Plan) approved by each Trusts 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, as applicable. Deferred compensation liabilities, if any, are included in the Trustees and Officers 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.

Indemnifications: In the normal course of business, a Trust enters into contracts that contain a variety of representations that provide general indemnification. A Trusts 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: Each Trusts investments are valued at fair value (also referred to as market value within the financial statements) each day that the Trust is open for business and, for financial reporting purposes, as of the report date. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. Each Trust determines the fair values of its financial instruments using various independent dealers or pricing services under policies approved by the Board. If a securitys market price is not readily available or does not otherwise accurately represent the fair value of the security, the security will be valued in accordance with a policy approved by the Board as reflecting fair value. 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 Trusts assets and liabilities:

Equity investments traded on a recognized securities exchange are valued at that days official closing price, as applicable, on the exchange where the stock is primarily traded. Equity investments traded on a recognized exchange for which there were no sales on that day may be valued at the last available bid (long positions) or ask (short positions) price.

Fixed-income investments for which market quotations are readily available are generally valued using the last available bid price or current market quotations provided by independent dealers or third party pricing services. Floating rate loan interests are valued at the mean of the bid prices from one or more independent brokers or dealers as obtained from a third party pricing service. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data (e.g., recent representative bids and offers), market data, credit quality information, perceived market movements, news, and other relevant information. Certain fixed-income securities, including asset-backed and mortgage related securities may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless the Manager determines such method does not represent fair value.

Investments in open-end U.S. mutual funds (including money market funds) are valued at that days published NAV.

Futures contracts are valued based on that days last reported settlement or trade price on the exchange where the contract is traded.

Forward foreign currency exchange contracts are valued at the mean between the bid and ask prices and are determined as of the close of trading on the NYSE based on that days prevailing forward exchange rate for the underlying currencies.

Exchange-traded options are valued at the mean between the last bid and ask prices at the close of the options market in which the options trade. An exchange-traded option for which there is no mean price is valued at the last bid (long positions) or ask (short positions) price. If no bid or ask price is available, the prior days price will be used, unless it is determined that the prior days price no longer reflects the fair value of the option. Over-the-counter (OTC) options and options on swaps (swaptions) are valued by an independent pricing service using a mathematical model, which incorporates a number of market data factors, such as the trades and prices of the underlying instruments.

Swap agreements are valued utilizing quotes received daily by independent pricing services or through brokers, which are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades and values of the underlying reference instruments.

If events (e.g., a market closure, market volatility, company announcement or a natural disaster) occur that are expected to materially affect the value of such investment, or in the event that 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,

Notes to Financial Statements (unaudited) (continued)

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 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 arms-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.

For investments in equity or debt issued by privately held companies or funds (Private Company or collectively, the Private Companies) and other Fair Valued Investments, the fair valuation approaches that are used by the Global Valuation Committee and third party pricing services utilize one or a combination of, but not limited to, the following inputs.

	Standard Inputs Generally Considered By Third Party Pricing Services
Market approach	(i) recent market transactions, including subsequent
rounds of financing, in the underlying investment or comparable issuers; (ii) recapitalizations and other transactions
across the capital structure; and (iii) market multiples of comparable issuers.
Income approach	(i) future cash flows discounted to present and
adjusted as appropriate for liquidity, credit, and/or market risks; (ii) quoted prices for similar investments or
assets in active markets; and (iii) other risk factors, such as interest rates, yield curves,
volatilities, prepayment speeds, loss severities, credit risks, recovery rates, liquidation amounts and/or default rates.
Cost approach	(i) audited or unaudited financial statements, investor
communications and financial or operational metrics issued by the Private Company; (ii) changes in the valuation of
relevant indices or publicly traded companies comparable to the Private Company; (iii) relevant news and
other public sources; and (iv) known secondary market transactions in the Private Companys
interests and merger or acquisition activity in companies comparable to the Private Company.

Investments in series of preferred stock issued by Private Companies are typically valued utilizing market approach in determining the enterprise value of the company. Such investments often contain rights and preferences that differ from other series of preferred and common stock of the same issuer. Enterprise valuation techniques such as an option pricing model (OPM), a probability weighted expected return model (PWERM), current value method or a hybrid of those techniques are used, as deemed appropriate under the circumstances. The use of these valuation techniques involve a determination of the exit scenarios of the investment in order to appropriately allocate the enterprise value of the company among the various parts of its capital structure.

The Private Companies are not subject to the public company disclosure, timing, and reporting standards applicable to other investments held by a Trust. Typically, the most recently available information by a Private Company is as of a date that is earlier than the date a Trust is calculating its NAV. This factor may result in a difference between the value of the investment and the price a Trust could receive upon the sale of the investment.

Fair Value Hierarchy: Various inputs are used in determining the fair value of financial instruments. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting 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 marketcorroborated inputs); and

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 Committees assumptions used in determining the fair value of 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 Private Companies that may not have a secondary market and/or may have a limited number of investors. The categorization of a value determined for financial instruments is based on the pricing transparency of the financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

SECURITIES AND OTHER INVESTMENTS

Asset-Backed and Mortgage-Backed Securities: Asset-backed securities are generally issued as pass-through certificates or as debt instruments. Asset-backed securities issued as pass-through certificates represent undivided fractional ownership interests in an underlying pool of assets. Asset-backed securities issued as debt instruments, which are also known as collateralized obligations, are typically issued as the debt of a special purpose entity organized solely for the purpose of owning such assets and issuing such debt. Asset-backed securities are often backed by a pool of assets representing the obligations of a number of different parties. The yield characteristics of certain asset-backed securities may differ from traditional debt securities. One such major difference is that all or a principal part of the obligations may be prepaid at any time because

N O T E S T O F I N A N C I A L S T A T E M E N T S 45

Notes to Financial Statements (unaudited) (continued)

the underlying assets (i.e., loans) may be prepaid at any time. As a result, a decrease in interest rates in the market may result in increases in the level of prepayments as borrowers, particularly mortgagors, refinance and repay their loans. An increased prepayment rate with respect to an asset-backed security will have the effect of shortening the maturity of the security. In addition, a fund may subsequently have to reinvest the proceeds at lower interest rates. If a fund has purchased such an asset-backed security at a premium, a faster than anticipated prepayment rate could result in a loss of principal to the extent of the premium paid.

For mortgage pass-through securities (the Mortgage Assets) there are a number of important differences among the agencies and instrumentalities of the U.S. Government that issue mortgage-related securities and among the securities that they issue. For example, mortgage-related securities guaranteed by Ginnie Mae are guaranteed as to the timely payment of principal and interest by Ginnie Mae and such guarantee is backed by the full faith and credit of the United States. However, mortgage-related securities issued by Freddie Mac and Fannie Mae, including Freddie Mac and Fannie Mae guaranteed mortgage pass-through certificates, which are solely the obligations of Freddie Mac and Fannie Mae, are not backed by or entitled to the full faith and credit of the United States, but are supported by the right of the issuer to borrow from the U.S. Treasury.

Non-agency mortgage-backed securities are securities issued by non-governmental issuers and have no direct or indirect government guarantees of payment and are subject to various risks. Non-agency mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The ability of a borrower to repay a loan is dependent upon the income or assets of the borrower. A number of factors, including a general economic downturn, acts of God, terrorism, social unrest and civil disturbances, may impair a borrowers ability to repay its loans.

Collateralized Debt Obligations: Collateralized debt obligations (CDOs), including collateralized bond obligations (CBOs) and collateralized loan obligations (CLOs), are types of asset-backed securities. A CDO is an entity that is backed by a diversified pool of debt securities (CBOs) or syndicated bank loans (CLOs). The cash flows of the CDO can be split into multiple segments, called tranches, which will vary in risk profile and yield. The riskiest segment is the subordinated or equity tranche. This tranche bears the greatest risk of defaults from the underlying assets in the CDO and serves to protect the other, more senior, tranches from default in all but the most severe circumstances. Since it is shielded from defaults by the more junior tranches, a senior tranche will typically have higher credit ratings and lower yields than their underlying securities, and often receive investment grade ratings from one or more of the nationally recognized rating agencies. Despite the protection from the more junior tranches, senior tranches can experience substantial losses due to actual defaults, increased sensitivity to future defaults and the disappearance of one or more protecting tranches as a result of changes in the credit profile of the underlying pool of assets.

Multiple Class Pass-Through Securities: Multiple class pass-through securities, including collateralized mortgage obligations (CMOs) and commercial mortgage-backed securities, may be issued by Ginnie Mae, U.S. Government agencies or instrumentalities or by trusts formed by private originators of, or investors in, mortgage loans. In general, CMOs are debt obligations of a legal entity that are collateralized by a pool of residential or commercial mortgage loans or Mortgage Assets. The payments on these are used to make payments on the CMOs or multiple pass-through securities. Multiple class pass-through securities represent direct ownership interests in the Mortgage Assets. Classes of CMOs include interest only (IOs), principal only (POs), planned amortization classes and targeted amortization classes. IOs and POs are stripped mortgage-backed securities representing interests in a pool of mortgages, the cash flow from which has been separated into interest and principal components. IOs receive the interest portion of the cash flow while POs receive the principal portion. IOs and POs can be extremely volatile in response to changes in interest rates. As interest rates rise and fall, the value of IOs tends to move in the same direction as interest rates. POs perform best when prepayments on the underlying mortgages rise since this increases the rate at which the principal is returned and the yield to maturity on the PO. When payments on mortgages underlying a PO are slower than anticipated, the life of the PO is lengthened and the yield to maturity is reduced. If the underlying Mortgage Assets experience greater than anticipated prepayments of principal, a funds initial investment in the IOs may not fully recoup.

Stripped Mortgage-Backed Securities: Stripped mortgage-backed securities are typically issued by the U.S. Government, its agencies and instrumentalities. Stripped mortgage-backed securities are usually structured with two classes that receive different proportions of the interest (IOs) and principal (POs) distributions on a pool of Mortgage Assets. Stripped mortgage-backed securities may be privately issued.

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.

Capital Securities and Trust Preferred Securities: Capital securities, including trust preferred securities, are typically issued by corporations, generally in the form of interest-bearing notes with preferred securities characteristics. In the case of trust preferred securities, an affiliated business trust of a corporation issues these securities, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The securities can be structured with either a fixed or adjustable coupon that can have either a perpetual or stated maturity date. For trust preferred securities, the issuing bank or corporation pays interest to the trust, which is then distributed to holders of these securities as a dividend. Dividends can be deferred without creating an event of default or acceleration, although maturity cannot take place unless all cumulative payment obligations have been met. The deferral of payments does not affect the purchase or sale of these securities in the open market. These securities generally are rated below that of the issuing companys senior debt securities and are freely callable at the issuers option.

Warrants: Warrants entitle a fund to purchase a specified number of shares of common stock and are non-income producing. The purchase price and number of shares are subject to adjustment under certain conditions until the expiration date of the warrants, if any. If the price of the underlying stock does not rise above the strike price before the warrant expires, the warrant generally expires without any value and a fund will lose any amount it paid for the warrant. Thus, investments in warrants may involve more risk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.

Floating Rate Loan Interests: Floating rate loan interests are typically issued to companies (the borrower) by banks, other financial institutions, or privately and publicly offered corporations (the lender). Floating rate loan interests are generally non-investment grade, often involve borrowers whose financial condition is troubled or uncertain and companies that are highly leveraged or in bankruptcy proceedings. In addition, transactions in floating rate loan interests may settle on a delayed basis, which may result in proceeds from the sale not being readily available for a fund to make additional investments or meet its redemption obligations. Floating rate loan interests may include fully funded term loans or revolving lines of credit. Floating rate loan interests are typically senior in the corporate capital structure of the borrower. Floating rate loan interests generally pay interest at rates that are periodically determined by reference to a base lending rate plus a premium. Since the rates reset only periodically, changes in prevailing

Notes to Financial Statements (unaudited) (continued)

interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of a fund to the extent that it invests in floating rate loan interests. The base lending rates are generally the lending rate offered by one or more European banks, such as the London Interbank Offered Rate (LIBOR), the prime rate offered by one or more U.S. banks or the certificate of deposit rate. Floating rate loan interests may involve foreign borrowers, and investments may be denominated in foreign currencies. These investments are treated as investments in debt securities for purposes of a funds investment policies.

When a fund purchases a floating rate loan interest, it may receive a facility fee and when it sells a floating rate loan interest, it may pay a facility fee. On an ongoing basis, a fund may receive a commitment fee based on the undrawn portion of the underlying line of credit amount of a floating rate loan interest. Facility and commitment fees are typically amortized to income over the term of the loan or term of the commitment, respectively. Consent and amendment fees are recorded to income as earned. Prepayment penalty fees, which may be received by a fund upon the prepayment of a floating rate loan interest by a borrower, are recorded as realized gains. A fund may invest in multiple series or tranches of a loan. A different series or tranche may have varying terms and carry different associated risks.

Floating rate loan interests are usually freely callable at the borrowers option. A fund may invest in such loans in the form of participations in loans (Participations) or assignments (Assignments) of all or a portion of loans from third parties. Participations typically will result in a fund having a contractual relationship only with the lender, not with the borrower. A fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the Participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing Participations, a fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights of offset against the borrower. A fund may not benefit directly from any collateral supporting the loan in which it has purchased the Participation. As a result, a fund assumes the credit risk of both the borrower and the lender that is selling the Participation. A funds investment in loan participation interests involves the risk of insolvency of the financial intermediaries who are parties to the transactions. In the event of the insolvency of the lender selling the Participation, a fund may be treated as a general creditor of the lender and may not benefit from any offset between the lender and the borrower. Assignments typically result in a fund having a direct contractual relationship with the borrower, and a fund may enforce compliance by the borrower with the terms of the loan agreement.

In connection with floating rate loan interests, the Trusts may also enter into unfunded floating rate loan interests (commitments). In connection with these commitments, a fund earns a commitment fee, typically set as a percentage of the commitment amount.

Such fee income, which is included in interest income in the Statements of Operations, is recognized ratably over the commitment period. Unfunded floating rate loan interests are marked-to-market daily, and any unrealized appreciation (depreciation) is included in the Statements of Assets and Liabilities and Statements of Operations. As of period end, the Trusts had the following unfunded floating rate loan interests:

Trust Name	Borrower	Par	Commitment Amount	Value	Unrealized Appreciation (Depreciation)
BGIO	LBM Acquisition LLC	$ 4,519	$ 4,474	$ 4,484	$ 10

Forward Commitments, When-Issued and Delayed Delivery Securities: The 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 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 Trusts maximum amount of loss is the unrealized appreciation of unsettled when-issued transactions.

TBA Commitments: TBA commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate and mortgage terms. When entering into TBA commitments, a fund may take possession of or deliver the underlying mortgage-backed securities but can extend the settlement or roll the transaction. TBA commitments involve a risk of loss if the value of the security to be purchased or sold declines or increases, respectively, prior to settlement date, if there are expenses or delays in connection with the TBA transactions, or if the counterparty fails to complete the transaction.

In order to better define contractual rights and to secure rights that will help a fund mitigate its counterparty risk, TBA commitments may be entered into by a fund under Master Securities Forward Transaction Agreements (each, an MSFTA). An MSFTA typically contains, among other things, collateral posting terms and netting provisions in the event of default and/or termination event. The collateral requirements are typically calculated by netting the mark-to-market amount for each transaction under such agreement and comparing that amount to the value of the collateral currently pledged by a fund and the counterparty. Cash collateral that has been pledged to cover the obligations of a fund and cash collateral received from the counterparty, if any, is reported separately in the Statements of Assets and Liabilities as cash pledged as collateral for TBA commitments or cash received as collateral for TBA commitments, respectively. Non-cash collateral pledged by a fund, if any, is noted in the Schedules of Investments. Typically, a fund is permitted to sell, re-pledge or use the collateral it receives; however, the counterparty is not permitted to do so. To the extent amounts due to a fund are not fully collateralized, contractually or otherwise, a fund bears the risk of loss from counterparty non-performance.

Mortgage Dollar Roll Transactions: The Trusts may sell TBA mortgage-backed securities and simultaneously contract to repurchase substantially similar (i.e., same type, coupon and maturity) securities on a specific future date at an agreed upon price. During the period between the sale and repurchase, a fund is not entitled to receive interest and principal payments on the securities sold. Mortgage dollar roll transactions are treated as purchases and sales and a fund realizes gains and losses on these transactions. Mortgage dollar rolls involve the risk that the market value of the securities that a fund is required to purchase may decline below the agreed upon repurchase price of those securities.

Borrowed Bond Agreements: Repurchase agreements may be referred to as borrowed bond agreements when entered into in connection with short sales of bonds. In a borrowed bond agreement, a fund borrows a bond from a counterparty in exchange for cash collateral. The agreement contains a commitment that the security and the cash will be returned to the counterparty and a fund at a mutually agreed upon date. Certain agreements have no stated maturity and can be terminated by either party at any time. Earnings on cash collateral and compensation to the lender of the bond are based on agreed upon rates between a fund and the counterparty. The value of the underlying cash

N O T E S T O F I N A N C I A L S T A T E M E N T S 47

Notes to Financial Statements (unaudited) (continued)

collateral approximates the market value and accrued interest of the borrowed bond. To the extent that a borrowed bond transaction exceeds one business day, the value of the cash collateral in the possession of the counterparty is monitored on a daily basis to ensure the adequacy of the collateral. As the market value of the borrowed bond changes, the cash collateral is periodically increased or decreased with a frequency and in amounts prescribed in the borrowed bond agreement. A fund may also experience delays in gaining access to the collateral.

Reverse Repurchase Agreements: Reverse repurchase agreements are agreements with qualified third party broker dealers in which a fund sells securities to a bank or broker-dealer and agrees to repurchase the same securities at a mutually agreed upon date and price. A fund receives cash from the sale to use for other investment purposes. During the term of the reverse repurchase agreement, a fund continues to receive the principal and interest payments on the securities sold. Certain agreements have no stated maturity and can be terminated by either party at any time. Interest on the value of the reverse repurchase agreements issued and outstanding is based upon competitive market rates determined at the time of issuance. A fund may utilize reverse repurchase agreements when it is anticipated that the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction. Reverse repurchase agreements involve leverage risk. If a fund suffers a loss on its investment of the transaction proceeds from a reverse repurchase agreement, a fund would still be required to pay the full repurchase price. Further, a fund remains subject to the risk that the market value of the securities repurchased declines below the repurchase price. In such cases, a fund would be required to return a portion of the cash received from the transaction or provide additional securities to the counterparty.

Cash received in exchange for securities delivered plus accrued interest due to the counterparty is recorded as a liability in the Statements of Assets and Liabilities at face value including accrued interest. Due to the short-term nature of the reverse repurchase agreements, face value approximates fair value. Interest payments made by a fund to the counterparties are recorded as a component of interest expense in the Statements of Operations. In periods of increased demand for the security, a fund may receive a fee for the use of the security by the counterparty, which may result in interest income to a fund.

For the six months ended June 30, 2021, the average amount of reverse repurchase agreements outstanding and the daily weighted average interest rate for the Trusts were as follows:

Trust Name	Average Amount Outstanding
BGIO	$ 16,192,525	0.68 %
BKT	140,209,316	0.11

Borrowed bond agreements and reverse repurchase transactions are entered into by a fund under Master Repurchase Agreements (each, an MRA), which permit a fund, under certain circumstances, including an event of default (such as bankruptcy or insolvency), to offset payables and/or receivables under the MRA with collateral held and/or posted to the counterparty and create one single net payment due to or from a fund. With borrowed bond agreements and reverse repurchase transactions, typically a fund and counterparty under an MRA are permitted to sell, re-pledge, or use the collateral associated with the transaction. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of the MRA counterpartys bankruptcy or insolvency. Pursuant to the terms of the MRA, a fund receives or posts securities and cash as collateral with a market value in excess of the repurchase price to be paid or received by a fund upon the maturity of the transaction. Upon a bankruptcy or insolvency of the MRA counterparty, a fund is considered an unsecured creditor with respect to excess collateral and, as such, the return of excess collateral may be delayed.

As of period end, the following table is a summary of BKTs open borrowed bond agreements and reverse repurchase agreements by counterparty which are subject to offset under an MRA on a net basis:

BKT — Counterparty	Borrowed Bonds Agreements (a)	Reverse Repurchase Agreements	Borrowed Bonds at Value including Accrued Interest (b)	Net Amount before Collateral	Non-cash Collateral Received	Cash Collateral Received	Fair Value of Non-cash Collateral Pledged Including Accrued Interest (c)	Cash Collateral Pledged	Net Collateral (Received)/ Pledged	Net Exposure Due (to)/ from Counterparty (d)

Notes to Financial Statements (unaudited) (continued)

(d) Net exposure represents the net receivable (payable) that would be due from/to the counterparty in the event of default.

In the event the counterparty of securities under an MRA files for bankruptcy or becomes insolvent, a funds use of the proceeds from the agreement may be restricted while the counterparty, or its trustee or receiver, determines whether or not to enforce a funds obligation to repurchase the securities.

Short Sale Transactions: In short sale transactions, a fund sells a security it does not hold in anticipation of a decline in the market price of that security. When a fund makes a short sale, it will borrow the security sold short (borrowed bond) and deliver the fixed-income security to the counterparty to which it sold the security short. An amount equal to the proceeds received by a fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the market value of the short sale. A fund is required to repay the counterparty interest on the security sold short, which, if applicable, is included in interest expense in the Statements of Operations. A fund is exposed to market risk based on the amount, if any, that the market value of the security increases beyond the market value at which the position was sold. Thus, a short sale of a security involves the risk that instead of declining, the price of the security sold short will rise. The short sale of securities involves the possibility of an unlimited loss since there is an unlimited potential for the market price of the security sold short to increase. A gain is limited to the price at which a fund sold the security short. A realized gain or loss is recognized upon the termination of a short sale if the market price is either less than or greater than the proceeds originally received. There is no assurance that a fund will be able to close out a short position at a particular time or at an acceptable price.

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 OTC.

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 exchange-traded 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 contracts 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, are 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 rates, foreign currency exchange rates or underlying assets.

Forward Foreign Currency Exchange Contracts: Forward foreign currency exchange contracts are entered into to gain or reduce exposure to foreign currencies (foreign currency exchange rate risk).

A forward foreign currency exchange contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a specified date. These contracts help to manage the overall exposure to the currencies in which some of the investments held by the Trusts are denominated and in some cases, may be used to obtain exposure to a particular market. The contracts are traded OTC and not on an organized exchange.

The contract is marked-to-market daily and the change in market value is recorded as unrealized appreciation (depreciation) in the Statements of Assets and Liabilities. When a contract is closed, a realized gain or loss is recorded in the Statements of Operations equal to the difference between the value at the time it was opened and the value at the time it was closed. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in cash without the delivery of foreign currency. The use of forward foreign currency exchange contracts involves the risk that the value of a forward foreign currency exchange contract changes unfavorably due to movements in the value of the referenced foreign currencies, and such value may exceed the amount(s) reflected in the Statements of Assets and Liabilities. Cash amounts pledged for forward foreign currency exchange contracts are considered restricted and are included in cash pledged as collateral for OTC derivatives in the Statements of Assets and Liabilities. A Trusts risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Trust.

Options: The Trusts may purchase and write call and put options to increase or decrease their exposure to the risks of underlying instruments, including equity risk, interest rate risk and/or commodity price risk and/or, in the case of options written, to generate gains from options premiums.

A call option gives the purchaser (holder) of the option the right (but not the obligation) to buy, and obligates the seller (writer) to sell (when the option is exercised) the underlying instrument at the exercise or strike price at any time or at a specified time during the option period. A put option gives the holder the right to sell and obligates the writer to buy the underlying instrument at the exercise or strike price at any time or at a specified time during the option period.

Premiums paid on options purchased and premiums received on options written, as well as the daily fluctuation in market value, are included in investments at value unaffiliated and options written at value, respectively, in the Statements of Assets and Liabilities. When an instrument is purchased or sold through the exercise of an option, the premium is offset against the cost or proceeds of the underlying instrument. When an option expires, a realized gain or loss is recorded in the Statements of Operations to the extent of the premiums received or paid. When an option is closed or sold, a gain or loss is recorded in the Statements of Operations to the extent the cost of the closing transaction exceeds the premiums received or paid. When the Trusts write a call option, such option is typically covered, meaning that they hold the underlying instrument

N O T E S T O F I N A N C I A L S T A T E M E N T S 49

Notes to Financial Statements (unaudited) (continued)

subject to being called by the option counterparty. When the Trusts write a put option, cash is segregated in an amount sufficient to cover the obligation. These amounts, which are considered restricted, are included in cash pledged as collateral for options written in the Statements of Assets and Liabilities.

Swaptions The Trusts may purchase and write options on swaps (swaptions) primarily to preserve a return or spread on a particular investment or portion of the Trusts holdings, as a duration management technique or to protect against an increase in the price of securities it anticipates purchasing at a later date. The purchaser and writer of a swaption is buying or granting the right to enter into a previously agreed upon interest rate or credit default swap agreement (interest rate risk and/or credit risk) at any time before the expiration of the option.

In purchasing and writing options, the Trusts bear the risk of an unfavorable change in the value of the underlying instrument or the risk that they may not be able to enter into a closing transaction due to an illiquid market. Exercise of a written option could result in the Trusts purchasing or selling a security when they otherwise would not, or at a price different from the current market value.

Swaps: Swap contracts are entered into to manage exposure to issuers, markets and securities. Such contracts are agreements between the Trusts and a counterparty to make periodic net payments on a specified notional amount or a net payment upon termination. Swap agreements are privately negotiated in the OTC market and may be entered into as a bilateral contract (OTC swaps) or centrally cleared (centrally cleared swaps).

For OTC swaps, any upfront premiums paid and any upfront fees received are shown as swap premiums paid and swap premiums received, respectively, in the Statements of Assets and Liabilities and amortized over the term of the contract. The daily fluctuation in market value is recorded as unrealized appreciation (depreciation) on OTC Swaps in the Statements of Assets and Liabilities. Payments received or paid are recorded in the Statements of Operations as realized gains or losses, respectively. When an OTC swap is terminated, a realized gain or loss is recorded in the Statements of Operations equal to the difference between the proceeds from (or cost of) the closing transaction and the Trusts basis in the contract, if any. Generally, the basis of the contract is the premium received or paid.

In a centrally cleared swap, immediately following execution of the swap contract, the swap contract is novated to a central counterparty (the CCP) and the CCP becomes the Trusts counterparty on the swap. Each Trust is required to interface with the CCP through the broker. Upon entering into a centrally cleared swap, each Trust is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Securities deposited as initial margin are designated in the Schedules of Investments and cash deposited is shown as cash pledged for centrally cleared swaps in the Statements of Assets and Liabilities. Amounts pledged, which are considered restricted cash, are included in cash pledged for centrally cleared swaps in the Statements of Assets and Liabilities. Pursuant to the contract, each Trust agrees 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 shown as variation margin receivable (or payable) on centrally cleared swaps in the Statements of Assets and Liabilities. Payments received from (paid to) the counterparty are amortized over the term of the contract and recorded as realized gains (losses) in the Statements of Operations, including those at termination.

Credit default swaps Credit default swaps are entered into to manage exposure to the market or certain sectors of the market, to reduce risk exposure to defaults of corporate and/or sovereign issuers or to create exposure to corporate and/or sovereign issuers to which a fund is not otherwise exposed (credit risk).

The Trusts may either buy or sell (write) credit default swaps on single-name issuers (corporate or sovereign), a combination or basket of single-name issuers or traded indexes. Credit default swaps are agreements in which the protection buyer pays fixed periodic payments to the seller in consideration for a promise from the protection seller to make a specific payment should a negative credit event take place with respect to the referenced entity (e.g., bankruptcy, failure to pay, obligation acceleration, repudiation, moratorium or restructuring). As a buyer, if an underlying credit event occurs, the Trusts will either (i) receive from the seller an amount equal to the notional amount of the swap and deliver the referenced security or underlying securities comprising the index, or (ii) receive a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising the index. As a seller (writer), if an underlying credit event occurs, the Trusts will either pay the buyer an amount equal to the notional amount of the swap and take delivery of the referenced security or underlying securities comprising the index or pay a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising the index.

Interest rate swaps Interest rate swaps are entered into to gain or reduce exposure to interest rates or to manage duration, the yield curve or interest rate (interest rate risk).

Interest rate swaps are agreements in which one party pays a stream of interest payments, either fixed or floating, in exchange for another partys stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. In more complex interest rate swaps, the notional principal amount may decline (or amortize) over time.

Swap transactions involve, to varying degrees, elements of interest rate, credit and market risk in excess of the amounts recognized in the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

Master Netting Arrangements: In order to define its contractual rights and to secure rights that will help it mitigate its counterparty risk, a Trust may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its counterparties. An ISDA Master Agreement is a bilateral agreement between a Trust and a counterparty that governs certain OTC derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, a Trust may, under certain circumstances, offset with the counterparty certain derivative financial instruments payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

Notes to Financial Statements (unaudited) (continued)

Collateral Requirements: For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark-to-market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by the Trust and the counterparty.

Cash collateral that has been pledged to cover obligations of the Trusts and cash collateral received from the counterparty, if any, is reported separately in the Statements of Assets and Liabilities as cash pledged as collateral and cash received as collateral, respectively. Non-cash collateral pledged by the Trusts, if any, is noted in the Schedules of Investments. Generally, the amount of collateral due from or to a counterparty is subject to a certain minimum transfer amount threshold before a transfer is required, which is determined at the close of business of the Trusts. Any additional required collateral is delivered to/pledged by the Trusts on the next business day. Typically, the counterparty is not permitted to sell, re-pledge or use cash and non-cash collateral it receives. A Trust generally agrees not to use non-cash collateral that it receives but may, absent default or certain other circumstances defined in the underlying ISDA Master Agreement, be permitted to use cash collateral received. In such cases, interest may be paid pursuant to the collateral arrangement with the counterparty. To the extent amounts due to the Trusts from the counterparties are not fully collateralized, each Trust bears the risk of loss from counterparty non-performance. Likewise, to the extent the Trusts have delivered collateral to a counterparty and stand ready to perform under the terms of their agreement with such counterparty, each Trust bears the risk of loss from a counterparty in the amount of the value of the collateral in the event the counterparty fails to return such collateral. Based on the terms of agreements, collateral may not be required for all derivative contracts.

For financial reporting purposes, the Trusts do not offset derivative assets and derivative liabilities that are subject to netting arrangements, if any, in the Statements of Assets and Liabilities.

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 Trusts portfolio and provides the personnel, facilities, equipment and certain other services necessary to the operations of each Trust.

For such services, BGIO pays the Manager a monthly fee at an annual rate equal to 0.60% of the average daily value of the Trusts managed assets. For purposes of calculating this fee, 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).

For such services, BKT pays the Manager a monthly fee at an annual rate equal to 0.65% of the average weekly value of the Trusts net assets. For purposes of calculating this fee, net assets means the total assets of the Trust minus the sum of its accrued liabilities (including the aggregate indebtedness constituting financial leverage).

With respect to each Trust, the Manager entered into separate sub-advisory agreements with BlackRock International Limited (BIL) and with respect to BGIO, BlackRock (Singapore) Limited (BRS) (collectively, the Sub-Advisers), each an affiliate of the Manager. The Manager pays BIL and BRS for services they provide for that portion of each Trust for which BIL and BRS, as applicable, acts as sub-adviser, a monthly fee that is equal to a percentage of the investment advisory fees paid by each Trust to the Manager.

Administration: BKT has an Administration Agreement with the Manager. The administration fee paid monthly to the Manager is computed at an annual rate of 0.15% of the Trusts average weekly net assets. For BKT, the Manager may reduce or discontinue these arrangements at any time without notice.

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, 2022. 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. These amounts are included in fees waived and/or reimbursed by the Manager in the Statements of Operations. For the six months ended June 30, 2021, the amounts waived were as follows:

Trust Name	Fees Waived and/or Reimbursed by the Manager
BGIO	$ 2,533
BKT	2,558

The Manager contractually agreed to waive its investment advisory fee with respect to any portion of each Trusts assets invested in affiliated equity and fixed-income mutual funds and affiliated exchange-traded funds that have a contractual management fee through June 30, 2022. 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 Trusts Independent Trustees. For the six months ended June 30, 2021, there were no fees waived by the Manager pursuant to this arrangement.

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.

PURCHASES AND SALES

For the six months ended June 30, 2021, purchases and sales of investments, including paydowns/payups and mortgage dollar rolls and excluding short-term securities, were as follows:

Trust Name	Purchases	Sales
BGIO	$ 27,052,839	$ 83,908,747
BKT	452,494,580	457,418,994

Trust Name	Purchases	Sales
BKT	$ 249,838,933	$ 250,208,794

INCOME TAX INFORMATION

It is each Trusts 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 Trusts U.S. federal tax returns generally remains open for a period of three fiscal years after they are filed. The statutes of limitations on each Trusts 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 June 30, 2021, 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 December 31, 2020, the Trusts had non-expiring capital loss carryforwards available to offset future realized capital gains as follows:

Trust Name	Non-Expiring
BGIO	$ 15,562,507
BKT	92,959,362

As of June 30, 2021, gross unrealized appreciation and depreciation based on cost of investments (including short positions and derivatives, if any) for U.S. federal income tax purposes were as follows:

Trust Name	Tax Cost	Gross Unrealized Appreciation	Gross Unrealized Depreciation		Net Unrealized Appreciation (Depreciation)
BGIO	$ 187,655,111	$ 10,148,931	$ (4,793,883	)	$ 5,355,048
BKT	608,597,602	34,481,415	(21,373,153	)	13,108,262

PRINCIPAL RISKS

In the normal course of business, the 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 the Trusts and their investments.

BGIO will terminate on or around December 31, 2021. BGIO is not a target term fund and thus does not seek to return its initial public offering price of $10.00 per common share upon termination. The final distribution of net assets upon termination may be more than, equal to or less than $10.00 per common share.

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 a Trust could sell such investments if they were more widely traded and, as a result of such illiquidity, a 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 Trusts NAV 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.

Market Risk: 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 income from each Trusts 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 portfolios current earnings rate.

An outbreak of respiratory disease caused by a novel coronavirus has developed into a global pandemic and has resulted in closing borders, quarantines, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of this pandemic, and other global health crises that may arise in the future, 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. This pandemic may result in substantial market volatility and may adversely impact the prices and liquidity of a funds investments. The duration of this pandemic and its effects cannot be determined with certainty.

Investment Objective Risk: There is no assurance that BGIO will achieve its investment objective. A variety of circumstances may make it extremely difficult for BGIO to achieve its investment objective. Such circumstances include, but may not be limited to, the existence of an inverted yield curve, a rapid and significant increase in interest rates, a significant decrease in issuer credit quality generally and/or increased defaults, increased volatility in currency markets and/or in currency exchange rates and negative

52 2 0 2 1 B L A C K R O C K S E M I - A N N U A L R E P O R T T O S H A R E H O L D E R S

Notes to Financial Statements (unaudited) (continued)

economic, market, political and/or social developments impacting emerging markets. Additionally, the limited term of BGIO may increase the risk that BGIO may not meet its investment objective. A limited term limits the period during which BGIO can generate returns and increases the potential impact that a disruptive market event or one or more of the conditions outlined above could have on BGIOs annualized returns.

Valuation Risk: The price a Trust could receive upon the sale of any particular portfolio investment may differ from a Trusts valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair valuation technique or a price provided by an independent pricing service. Changes to significant unobservable inputs and assumptions (i.e., publicly traded company multiples, growth rate, time to exit) due to the lack of observable inputs may significantly impact the resulting fair value and therefore a Trusts results of operations. As a result, the price received upon the sale of an investment may be less than the value ascribed by a Trust, and a Trust could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. A Trusts ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers.

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, including making timely interest and/or principal payments or otherwise honoring its obligations. 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.

For OTC options purchased, each Trust bears the risk of loss in the amount of the premiums paid plus the positive change in market values net of any collateral held by the Trusts should the counterparty fail to perform under the contracts. Options written by the Trusts do not typically give rise to counterparty credit risk, as options written generally obligate the Trusts, and not the counterparty, to perform. The Trusts may be exposed to counterparty credit risk with respect to options written to the extent each Trust deposits collateral with its counterparty to a written option.

With exchange-traded futures and centrally cleared swaps, 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 brokers 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 brokers customers, potentially resulting in losses to the Trusts.

Concentration Risk: A diversified portfolio, where this is appropriate and consistent with a funds objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within each Trusts portfolio are disclosed in its Schedule of Investments.

Certain Trusts invest a significant portion of their assets in high yield securities. High yield securities that are rated below investment-grade (commonly referred to as junk bonds) or are unrated may be deemed speculative, involve greater levels of risk than higher-rated securities of similar maturity and are more likely to default. High yield securities may be issued by less creditworthy issuers, and issuers of high yield securities may be unable to meet their interest or principal payment obligations. High yield securities are subject to extreme price fluctuations, may be less liquid than higher rated fixed-income securities, even under normal economic conditions, and frequently have redemption features.

Certain 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.

Certain Trusts invest a significant portion of their assets in securities backed by commercial or residential mortgage loans or in issuers that hold mortgage and other asset-backed securities. When a Trust concentrates its investments in this manner, it assumes a greater risk of prepayment or payment extension by securities issuers. Changes in economic conditions, including delinquencies and/or defaults on assets underlying these securities, can affect the value, income and/or liquidity of such positions. Investment percentages in these securities are presented in the Schedules of Investments.

LIBOR Transition Risk: The United Kingdoms Financial Conduct Authority announced a phase out of the London Interbank Offered Rate (LIBOR). Although many LIBOR rates will be phased out by the end of 2021, a selection of widely used USD LIBOR rates will continue to be published through June 2023 in order to assist with the transition. The Trusts may be exposed to financial instruments tied to LIBOR to determine payment obligations, financing terms, hedging strategies or investment value. The transition process away from LIBOR might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of new hedges placed against, instruments whose terms currently include LIBOR. The ultimate effect of the LIBOR transition process on the Trusts is uncertain.

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements

The Boards of Trustees/Directors, as applicable (together, the Board, the members of which are referred to as Board Members) of BlackRock 2022 Global Income Opportunity Trust (BGIO) and BlackRock Income Trust, Inc. (BKT and together with BGIO, the Funds and each, a Fund) met on May 4, 2021 (the May Meeting) and June 8-9, 2021 (the June Meeting) to consider the approval to continue the investment advisory agreements (the Advisory Agreements) or (the Agreements) between each Fund and BlackRock Advisors, LLC (the Manager), each Funds investment advisor. The Board also considered the approval to continue the sub-advisory agreements (the Sub-Advisory Agreements) between (1) the Manager, BlackRock International Limited (BIL) and each Fund and (2) the Manager, BlackRock (Singapore) Limited (BRS and together with BIL, the Sub-Advisors) and BGIO. The Manager and the Sub-Advisors are referred to herein as BlackRock. The Advisory Agreements and the Sub-Advisory Agreements are referred to herein as the Agreements.

The Approval Process

Consistent with the requirements of the Investment Company Act of 1940 (the 1940 Act), the Board considers the approval of the continuation of the Agreements for each Fund on an annual basis. The Board members whom are not interested persons of each Fund, as defined in the 1940 Act, are considered independent Board members (the Independent Board Members). The Boards consideration entailed a year-long deliberative process during which the Board and its committees assessed BlackRocks various services to each Fund, including through the review of written materials and oral presentations, and the review of additional information provided in response to requests from the Independent Board Members. The Board had four quarterly meetings per year, each typically extending for two days, as well as additional ad hoc meetings and executive sessions throughout the year, as needed. The committees of the Board similarly met throughout the year. The Board also had a fifth one-day meeting to consider specific information surrounding the renewal of the Agreements. In particular, the Board assessed, among other things, the nature, extent and quality of the services provided to each Fund by BlackRock, BlackRocks personnel and affiliates, including (as applicable): investment management services; accounting oversight; administrative and shareholder services; oversight of each Funds service providers; risk management and oversight; and legal, regulatory and compliance services. Throughout the year, including during the contract renewal process, the Independent Board Members were advised by independent legal counsel, and met with independent legal counsel in various executive sessions outside of the presence of BlackRocks management.

During the year, the Board, acting directly and through its committees, considered information that was relevant to its annual consideration of the renewal of the Agreements, including the services and support provided by BlackRock to each Fund and its shareholders. BlackRock also furnished additional information to the Board in response to specific questions from the Board. Among the matters the Board considered were: (a) investment performance for one-year, three-year, five-year, and/or since inception periods, as applicable, against peer funds, relevant benchmarks, and other performance metrics, as applicable, as well as BlackRock senior managements and portfolio managers analyses of the reasons for any outperformance or underperformance relative to its peers, benchmarks, and other performance metrics, as applicable; (b) leverage management, as applicable; (c) fees, including advisory, administration, if applicable, and other amounts paid to BlackRock and its affiliates by each Fund for services; (d) Fund operating expenses and how BlackRock allocates expenses to each Fund; (e) the resources devoted to risk oversight of, and compliance reports relating to, implementation of each Funds investment objective, policies and restrictions, and meeting regulatory requirements; (f) BlackRocks and each Funds adherence to applicable compliance policies and procedures; (g) the nature, character and scope of non-investment management services provided by BlackRock and its affiliates and the estimated cost of such services, as available; (h) BlackRocks and other service providers internal controls and risk and compliance oversight mechanisms; (i) BlackRocks implementation of the proxy voting policies approved by the Board; (j) execution quality of portfolio transactions; (k) BlackRocks implementation of each Funds valuation and liquidity procedures; (l) an analysis of management fees paid to BlackRock for products with similar investment mandates across the open-end fund, closed-end fund, sub-advised mutual fund, collective investment trust and institutional separate account product channels, as applicable, and the similarities and differences between these products and the services provided as compared to each Fund; (m) BlackRocks compensation methodology for its investment professionals and the incentives and accountability it creates, along with investment professionals investments in the fund(s) they manage; (n) periodic updates on BlackRocks business; and (o) each Funds market discount/premium compared to peer funds.

Prior to and in preparation for the May Meeting, the Board received and reviewed materials specifically relating to the renewal of the Agreements. The Independent Board Members are continuously engaged in a process with their independent legal counsel and BlackRock to review the nature and scope of the information provided to the Board to better assist its deliberations. The materials provided in connection with the May Meeting included, among other things: (a) information independently compiled and prepared by Broadridge Financial Solutions, Inc. (Broadridge), based on Lipper classifications, regarding each Funds fees and expenses as compared with a peer group of funds as determined by Broadridge (Expense Peers) and the investment performance of each Fund as compared with a peer group of funds (Performance Peers); (b) information on the composition of the Expense Peers and Performance Peers and a description of Broadridges methodology; (c) information on the estimated profits realized by BlackRock and its affiliates pursuant to the Agreements and a discussion of fall-out benefits to BlackRock and its affiliates; (d) a general analysis provided by BlackRock concerning investment management fees received in connection with other types of investment products, such as institutional accounts, sub-advised mutual funds, closed-end funds, and open-end funds, under similar investment mandates, as applicable; (e) a review of non-management fees; (f) the existence, impact and sharing of potential economies of scale, if any, with each Fund; (g) a summary of aggregate amounts paid by each Fund to BlackRock; and (h) various additional information requested by the Board as appropriate regarding BlackRocks and each Funds operations.

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

At the June Meeting, the Board concluded its assessment of, among other things: (a) the nature, extent and quality of the services provided by BlackRock; (b) the investment performance of each Fund as compared to its Performance Peers and to other metrics, as applicable; (c) the advisory fee and the estimated cost of the services and estimated profits realized by BlackRock and its affiliates from their relationship with each Fund; (d) each Funds fees and expenses compared to its Expense Peers; (e) the existence and sharing of potential economies of scale; (f) any fall-out benefits to BlackRock and its affiliates as a result of BlackRocks relationship with each Fund; and (g) other factors deemed relevant by the Board Members.

The Board also considered other matters it deemed important to the approval process, such as other payments made to BlackRock or its affiliates relating to securities lending and cash management, and BlackRocks services related to the valuation and pricing of Fund portfolio holdings. The Board noted the willingness of BlackRocks personnel to

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (continued)

engage in open, candid discussions with the Board. The Board Members did not identify any particular information, or any single factor as determinative, and each Board Member may have attributed different weights to the various items and factors considered.

A. Nature, Extent and Quality of the Services Provided by BlackRock

The Board, including the Independent Board Members, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services, and the resulting performance of each Fund. Throughout the year, the Board compared Fund performance to the performance of a comparable group of closed-end funds, relevant benchmarks, and performance metrics, as applicable. The Board met with BlackRocks senior management personnel responsible for investment activities, including the senior investment officers. The Board also reviewed the materials provided by each Funds portfolio management team discussing each Funds performance, investment strategies and outlook.

The Board considered, among other factors, with respect to BlackRock: the number, education and experience of investment personnel generally and each Funds portfolio management team; research capabilities; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use of technology; commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also considered BlackRocks overall risk management program, including the continued efforts of BlackRock and its affiliates to address cybersecurity risks and the role of BlackRocks Risk & Quantitative Analysis Group. The Board engaged in a review of BlackRocks compensation structure with respect to each Funds portfolio management team and BlackRocks ability to attract and retain high-quality talent and create performance incentives.

In addition to investment advisory services, the Board considered the nature and quality of the administrative and other non-investment advisory services provided to each Fund. BlackRock and its affiliates provide each Fund with certain administrative, shareholder and other services (in addition to any such services provided to each Fund by third parties) and officers and other personnel as are necessary for the operations of each Fund. In particular, BlackRock and its affiliates provide each Fund with administrative services including, among others: (i) responsibility for disclosure documents, such as the prospectus and the statement of additional information in connection with the initial public offering and periodic shareholder reports; (ii) preparing communications with analysts to support secondary market trading of each Fund; (iii) oversight of daily accounting and pricing; (iv) responsibility for periodic filings with regulators and stock exchanges; (v) overseeing and coordinating the activities of third-party service providers including, among others, each Funds custodian, fund accountant, transfer agent, and auditor; (vi) organizing Board meetings and preparing the materials for such Board meetings; (vii) providing legal and compliance support; (viii) furnishing analytical and other support to assist the Board in its consideration of strategic issues such as the merger, consolidation or repurposing of certain closed-end funds; and (ix) performing or managing administrative functions necessary for the operation of each Fund, such as tax reporting, expense management, fulfilling regulatory filing requirements, and shareholder call center and other services. The Board reviewed the structure and duties of BlackRocks fund administration, shareholder services, and legal and compliance departments and considered BlackRocks policies and procedures for assuring compliance with applicable laws and regulations. The Board considered the operation of BlackRocks business continuity plans, including in light of the ongoing COVID-19 pandemic.

B. The Investment Performance of each Fund and BlackRock

The Board, including the Independent Board Members, reviewed and considered the performance history of each Fund throughout the year and at the May Meeting. In preparation for the May Meeting, the Board was provided with reports independently prepared by Broadridge, which included an analysis of each Funds performance as of December 31, 2020, as compared to its Performance Peers. The performance information is based on net asset value (NAV), and utilizes Lipper data. Lippers methodology calculates a funds total return assuming distributions are reinvested on the ex-date at a funds ex-date NAV. Broadridge ranks funds in quartiles, ranging from first to fourth, where first is the most desirable quartile position and fourth is the least desirable. In connection with its review, the Board received and reviewed information regarding the investment performance of each Fund as compared to its Performance Peers and, with respect to BKT, a custom peer group of funds as defined by BlackRock (Customized Peer Group) and the performance of each Fund as compared with its custom benchmark. The Board and its Performance Oversight Committee regularly review and meet with Fund management to discuss the performance of each Fund throughout the year.

In evaluating performance, the Board focused particular attention on funds with less favorable performance records. The Board also noted that while it found the data provided by Broadridge generally useful, it recognized the limitations of such data, including in particular, that notable differences may exist between a fund and its Performance Peers (for example, the investment objectives and strategies). Further, the Board recognized that the performance data reflects a snapshot of a period as of a particular date and that selecting a different performance period could produce significantly different results. The Board also acknowledged that long-term performance could be impacted by even one period of significant outperformance or underperformance, and that a single investment theme could have the ability to disproportionately affect long-term performance.

The Board noted that for each of the one-, three- and five-year periods reported, BGIO underperformed its customized benchmark. The Board noted that BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for BGIO, and that BlackRock has explained its rationale for this belief to the Board. The Board and BlackRock reviewed BGIOs underperformance relative to its customized benchmark during the applicable periods.

The Board noted that for each of the one-, three- and five-year periods reported, BKT underperformed its customized benchmark. The Board noted that BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for BKT, and that BlackRock has explained its rationale for this belief to the Board. The Board and BlackRock reviewed BKTs underperformance relative to its customized benchmark during the applicable periods.

The Board also considered alternative measures of performance when evaluating BKTs performance, including a high quality Customized Peer Group. The Customized Peer Group consists of closed-end funds that invest an average of 75% or greater of their portfolios in AAA-rated bonds, securities issued or guaranteed by the U.S. government or one of its agencies or instrumentalities and cash or cash equivalents. Relative to the Customized Peer Group as of 12/31/20, the Board noted that for each of the one-, three-, and five-year periods reported, BKT ranked in the third quartile.

C. Consideration of the Advisory/Management Fees and the Estimated Cost of the Services and Estimated Profits Realized by BlackRock and its Affiliates from their Relationship with each Fund

56 2 0 2 1 B L A C K R O C K S E M I - A N N U A L R E P O R T T O S H A R E H O L D E R S

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (continued)

The Board, including the Independent Board Members, reviewed each Funds contractual management fee rate compared with those of its Expense Peers. The contractual management fee rate represents a combination of the advisory fee and any administrative fees, before taking into account any reimbursements or fee waivers. The Board also compared each Funds total expense ratio, as well as its actual management fee rate as a percentage of managed assets, which is the total assets of each Fund (including any assets attributable to money borrowed for investment purposes) minus the sum of each Funds accrued liabilities (other than money borrowed for investment purposes) to those of its Expense Peers. The total expense ratio represents a funds total net operating expenses, excluding any investment related expenses. The total expense ratio gives effect to any expense reimbursements or fee waivers, and the actual management fee rate gives effect to any management fee reimbursements or waivers. The Board considered the services provided and the fees charged by BlackRock and its affiliates to other types of clients with similar investment mandates, as applicable, including institutional accounts and sub-advised mutual funds (including mutual funds sponsored by third parties).

The Board received and reviewed statements relating to BlackRocks financial condition. The Board reviewed BlackRocks profitability methodology and was also provided with an estimated profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to each Fund. The Board reviewed BlackRocks estimated profitability with respect to each Fund and other funds the Board currently oversees for the year ended December 31, 2020 compared to available aggregate estimated profitability data provided for the prior two years. The Board reviewed BlackRocks estimated profitability with respect to certain other U.S. fund complexes managed by the Manager and/or its affiliates. The Board reviewed BlackRocks assumptions and methodology of allocating expenses in the estimated profitability analysis, noting the inherent limitations in allocating costs among various advisory products. The Board recognized that profitability may be affected by numerous factors including, among other things, fee waivers and expense reimbursements by the Manager, the types of funds managed, precision of expense allocations and business mix. The Board thus recognized that calculating and comparing profitability at the individual fund level is difficult.

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

The Board considered whether BlackRock has the financial resources necessary to attract and retain high quality investment management personnel to perform its obligations under the Agreements and to continue to provide the high quality of services that is expected by the Board. The Board further considered factors including but not limited to BlackRocks commitment of time, assumption of risk, and liability profile in servicing each Fund, including in contrast to what is required of BlackRock with respect to other products with similar investment mandates across the open-end fund, closed-end fund, sub-advised mutual fund, collective investment trust, and institutional separate account product channels, as applicable.

The Board noted that BGIOs contractual management fee rate ranked in the first quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile, relative to the Expense Peers.

The Board noted that BKTs contractual management fee rate ranked in the first quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile, relative to the Expense Peers.

D. Economies of Scale

The Board, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of each Fund increase. The Board also considered the extent to which each Fund benefits from such economies of scale in a variety of ways, and whether there should be changes in the advisory fee rate or breakpoint structure in order to enable each Fund to more fully participate in these economies of scale. The Board considered each Funds asset levels and whether the current fee was appropriate.

Based on the Boards review and consideration of the issue, the Board concluded that most closed-end funds do not have fund level breakpoints because closed-end funds generally do not experience substantial growth after the initial public offering. Closed-end funds are typically priced at scale at a funds inception.

E. Other Factors Deemed Relevant by the Board Members

The Board, including the Independent Board Members, also took into account other ancillary or fall-out benefits that BlackRock or its affiliates may derive from BlackRocks respective relationships with each Fund, both tangible and intangible, such as BlackRocks ability to leverage its investment professionals who manage other portfolios and its risk management personnel, an increase in BlackRocks profile in the investment advisory community, and the engagement of BlackRocks affiliates as service providers to each Fund, including for administrative, securities lending and cash management services. The Board also considered BlackRocks overall operations and its efforts to expand the scale of, and improve the quality of, its operations. The Board also noted that, subject to applicable law, BlackRock may use and benefit from third-party research obtained by soft dollars generated by certain registered fund transactions to assist in managing all or a number of its other client accounts.

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

The Board noted the competitive nature of the closed-end fund marketplace, and that shareholders are able to sell their Fund shares in the secondary market if they believe that each Funds fees and expenses are too high or if they are dissatisfied with the performance of each Fund.

The Board also considered the various notable initiatives and projects BlackRock performed in connection with its closed-end fund product line. These initiatives included developing equity shelf programs; efforts to eliminate product overlap with fund mergers; ongoing services to manage leverage that has become increasingly complex; periodic evaluation of share repurchases and other support initiatives for certain BlackRock funds; and continued communication efforts with shareholders, fund analysts and financial advisers. With respect to the latter, the Independent Board Members noted BlackRocks continued commitment to supporting the secondary market for the common shares of its closed-end funds through a comprehensive secondary market communication program designed to raise investor and analyst awareness and understanding of closed-end

D I S C L O S U R E O F I N V E S T M E N T A D V I S O R Y A G R E E M E N T S A N D S U B - A D V I S O R Y A G R E E M E N T S 57

funds. BlackRocks support services included, among other things: sponsoring and participating in conferences; communicating with closed-end fund analysts covering the BlackRock funds throughout the year; providing marketing and product updates for the closed-end funds; and maintaining and enhancing its closed-end fund website.

Conclusion

The Board, including the Independent Board Members, unanimously approved the continuation of the Advisory Agreements between the Manager and each Fund for a one-year term ending June 30, 2022, and the Sub-Advisory Agreements among (1) the Manager, BIL and each Fund and (2) the Manager, BRS and BGIO for a one-year term ending June 30, 2022. Based upon its evaluation of all of the aforementioned factors in their totality, as well as other information, the Board, including the Independent Board Members, was satisfied that the terms of the Agreements were fair and reasonable and in the best interest of each Fund and its shareholders. In arriving at its decision to approve the Agreements, the Board did not identify any single factor or group of factors as all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination.

Additional Information

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 NYSEs 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.

Regulation Regarding Derivatives

On October 28, 2020, the Securities and Exchange Commission (the SEC) adopted new regulations governing the use of derivatives by registered investment companies (Rule 18f-4). The Trusts will be required to implement and comply with Rule 18f-4 by August 19, 2022. Once implemented, Rule 18f-4 will impose limits on the amount of derivatives a fund can enter into, eliminate the asset segregation framework currently used by funds to comply with Section 18 of the 1940 Act, treat derivatives as senior securities and require funds whose use of derivatives is more than a limited specified exposure amount to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager.

Environmental, Social and Governance (ESG) Integration

Although a Trust does not seek to implement a specific ESG, impact or sustainability strategy unless otherwise disclosed, Trust management will consider ESG characteristics as part of the investment process for actively managed Trusts. These considerations will vary depending on a Trusts particular investment strategies and may include consideration of third-party research as well as consideration of proprietary BlackRock research across the ESG risks and opportunities regarding an issuer. Trust management will consider those ESG characteristics it deems relevant or additive when making investment decisions for a Trust. The ESG characteristics utilized in a Trusts investment process are anticipated to evolve over time and one or more characteristics may not be relevant with respect to all issuers that are eligible for investment. ESG characteristics are not the sole considerations when making investment decisions for a Trust. Further, investors can differ in their views of what constitutes positive or negative ESG characteristics. As a result, a Trust may invest in issuers that do not reflect the beliefs and values with respect to ESG of any particular investor. ESG considerations may affect a Trusts exposure to certain companies or industries and a Trust may forego certain investment opportunities. While Trust management views ESG considerations as having the potential to contribute to a Trusts long-term performance, there is no guarantee that such results will be achieved.

Dividend Policy

BGIOs 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 dividend distributions, the distributions paid by BGIO for any particular month may be more or less than the amount of net investment income earned by BGIO during such month. The portion of distributions that exceeds BGIOs current and accumulated earnings and profits, which are measured on a tax basis, will constitute a nontaxable return of capital. BGIOs 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.

BKTs policy is to make monthly distributions to shareholders. In order to provide shareholders with a more stable level of dividend distributions, BKT employs a managed distribution plan (the Plan), the goal of which is to provide shareholders with consistent and predictable cash flows by setting distribution rates based on expected long-term returns of BKT.

The distributions paid by BKT for any particular month may be more or less than the amount of net investment income earned by BKT during such month. Furthermore, the final tax characterization of distributions is determined after the year-end of BKT and is reported in BKTs annual report to shareholders. Distributions can be characterized as ordinary income, capital gains and/or return of capital. BKTs taxable net investment income and net realized capital gains (taxable income) may not be sufficient to support the level of distributions paid. To the extent that distributions exceed BKTs current and accumulated earnings and profits, the excess may be treated as a non-taxable return of capital.

A return of capital is a return of a portion of an investors original investment. A return of capital is not expected to be taxable, but it reduces a shareholders tax basis in his or her shares, thus reducing any loss or increasing any gain on a subsequent disposition by the shareholder of his or her shares. It is possible that a substantial portion of the distributions paid during a calendar year may ultimately be classified as return of capital for U.S. federal income tax purposes when the final determination of the source and character of the distributions is made.

Such distributions, under certain circumstances, may exceed BKTs total return performance. When total distributions exceed total return performance for the period, the difference reduces BKTs total assets and net asset value per share (NAV) and, therefore, could have the effect of increasing BKTs expense ratio and reducing the amount of assets BKT has available for long term investment.
