Th e Markets in Review

Dear Shareholder,

In the 12 months ended December 31, 2017, risk assets, such as stocks and high-yield bonds, continued to deliver strong performance. The equity market advanced, month after month, despite geopolitical uncertainty and relatively high valuations, while bond returns were constrained by higher interest rates.

Rising interest rates worked against high-quality assets with more interest rate sensitivity. Consequently, longer-term U.S. Treasuries posted modest returns, as rising energy prices, modest wage increases, and steady job growth led to expectations of higher inflation and interest rate increases by the U.S. Federal Reserve (the “Fed”).

The market’s performance reflected reflationary expectations early in the reporting period, as investors began to sense that a global recovery was afoot. Thereafter, many countries throughout the world experienced sustained and synchronized growth for the first time since the financial crisis. Growth rates and inflation are still relatively low, but they are finally rising together.

The Fed responded to these positive developments by increasing short-term interest rates three times and setting expectations for additional interest rate increases. The Fed also began reducing the vast balance sheet reserves that had accumulated in the wake of the financial crisis. In October 2017, the Fed reduced its $4.5 trillion balance sheet by only $10 billion, while setting expectations for additional modest reductions and rate hikes in 2018.

By contrast, the European Central Bank (“ECB”) and the Bank of Japan (“BoJ”) both continued to expand their balance sheets despite nascent signs of sustained economic growth. The Eurozone and Japan are both approaching the limits of central banks’ ownership share of national debt, which is a structural pressure point that limits their capacity to deliver additional monetary stimulus. In October 2017, the ECB announced plans to cut the amount of its bond purchases in half for 2018, while the BoJ reiterated its commitment to economic stimulus until the inflation rate rises to its target of 2%.

Emerging market growth also stabilized, as accelerating growth in China, the second largest economy in the world and the most influential of all developing economies, improved the outlook for corporate profits and economic growth across most developing nations. Chinese demand for commodities and other raw materials allayed concerns about the country’s banking system, leading to rising equity prices and foreign investment flows.

While escalating tensions between the United States and North Korea and our nation’s divided politics are concerning, benign credit conditions, modest inflation, solid corporate earnings, and the positive outlook for growth in the world’s largest economies have kept markets relatively tranquil.

Rising consumer confidence and improving business sentiment are driving momentum for the U.S. economy. If the Fed maintains a measured pace of stimulus reduction, to the extent that inflation rises, it’s likely to be accompanied by rising real growth and higher wages. That could lead to a favorable combination of moderately higher inflation, steadily rising interest rates, and improving growth in 2018.

Further fueling optimism, Congress passed a sweeping tax reform bill in December 2017. The U.S. tax overhaul is likely to accentuate the reflationary themes already in place, including faster growth and rising interest rates. Changing the corporate tax rate to a flat 21% will create many winners and losers among high-and-low tax companies, while the windfall from lower taxes could boost business and consumer spending.

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

Sincerely,

Rob Kapito

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

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

Section 19(b) Disclosure

The Trusts, acting pursuant to a U.S. Securities and Exchange Commission (“SEC”) exemptive order and with the approval of each Trust’s Board of Trustees/Directors (the “Board”), each have adopted a plan, consistent with its investment objectives and policies to support a level distribution of income, capital gains and/or return of capital (the “Plan”). In accordance with the Plans, the Trusts distribute the following fixed amounts per share on a monthly basis as of December 31, 2017:

Exchange Symbol Amount Per Common Share
BGR $ 0.0776
CII 0.0828
BDJ 0.0467
BOE 0.0780
BME 0.2000
BGY 0.0380
BCX 0.0516
BST 0.1300
BUI 0.1210

The fixed amounts distributed per share are subject to change at the discretion of each Trust’s Board. Under its Plan, each Trust will distribute all available investment income to its shareholders, consistent with its primary investment objectives and as required by the Internal Revenue Code of 1986, as amended (the “Code”). If sufficient investment income is not available on a monthly basis, the Trusts will distribute long-term capital gains and/or return of capital to shareholders in order to maintain a level distribution. Each monthly distribution to shareholders is expected to be at the fixed amount established by the Board, except for extraordinary distributions and potential distribution rate increases or decreases to enable the Trusts to comply with the distribution requirements imposed by the Code.

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

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

The Benefits and Risks of Option Over-Writing

In general, the goal of each of the Trusts is to provide total return through a combination of current income and realized and unrealized gains (capital appreciation). The Trusts seek to pursue this goal primarily by investing in a portfolio of equity securities and utilizing an option over-writing strategy in an effort to enhance the Trusts’ distribution rate and total return performance. However, these objectives cannot be achieved in all market conditions.

The Trusts primarily write single stock covered call options, and may also from time to time write single stock put options. When writing (selling) a covered call option, the Trust holds an underlying equity security and enters into an option transaction which allows the counterparty to purchase the equity security at an agreed-upon price (“strike price”) within an agreed-upon time period. The Trusts receive cash premiums from the counterparties upon writing (selling) the option, which along with net investment income and net realized gains, if any, are generally available to support current or future distributions paid by the Trusts. During the option term, the counterparty may elect to exercise the option if the market value of the equity security rises above the strike price, and the Trust is obligated to sell the equity security to the counterparty at the strike price, realizing a gain or loss. Premiums received increase gains or reduce losses realized on the sale of the equity security. If the option remains unexercised upon its expiration, the Trusts realize gains equal to the premiums received. Alternatively, an option may be closed out by an offsetting purchase or sale of an option prior to expiration. The Trust realizes a capital gain from a closing purchase or sale transaction if the premium paid is less than the premium received from writing the option. The Trust realizes a capital loss from a closing purchase or sale transaction if the premium received is less than the premium paid to purchase the option.

Writing covered call options entails certain risks, which include, but are not limited to, the following: an increase in the value of the underlying equity security above the strike price can result in the exercise of a written option (sale by the Trust to the counterparty) when the Trust might not otherwise have sold the security; exercise of the option by the counterparty may result in a sale below the current market value and a gain or loss being realized by the Trust; and limiting the potential appreciation that could be realized on the underlying equity security to the extent of the strike price of the option. As such, an option over-writing strategy may outperform the general equity market in flat or falling markets but underperform in rising markets.

Each Trust employs a plan to support a level distribution of income, capital gains and/or return of capital. The goal of the plan is to provide shareholders with consistent and predictable cash flows by setting distribution rates based on expected long-term returns of the Trusts. Such distributions, under certain circumstances, may exceed a Trust’s total return performance. When total distributions exceed total return performance for the period, the difference reduces the Trust’s total assets and net asset value per share (“NAV”) and, therefore, could have the effect of increasing the Trust’s expense ratio and reducing the amount of assets, the Trust has available for long term investment. In order to make these distributions, a Trust may have to sell portfolio securities at less than opportune times.

The final tax characterization of distributions is determined after the fiscal year and is reported in the Trust’s annual report to shareholders. Distributions can be characterized as ordinary income, capital gains and/or return of capital. The Trust’s taxable net investment income or net realized capital gains (“taxable income”) may not be sufficient to support the level of distributions paid. To the extent that distributions exceed the Trust’s current and accumulated earnings and profits, the excess may be treated as a non-taxable return of capital. Distributions that exceed a Trust’s taxable income but do not exceed the Trust’s current and accumulated earnings and profits, may be classified as ordinary income which are taxable to shareholders. Such distributions are reported as distributions in excess of net investment income.

A return of capital distribution does not necessarily reflect a Trust’s investment performance and should not be confused with ‘yield’ or ‘income.’ A return of capital is a return of a portion of an investor’s original investment. A return of capital is not taxable, but it reduces a shareholder’s 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 or as distributions in excess of net investment income for U.S. federal income tax purposes when the final determination of the source and character of the distributions is made.

To illustrate these concepts, assume the following: (1) a common stock purchased at and currently trading at $37.15 per share; (2) a three-month call option is written by a Trust with a strike price of $40 (i.e., 7.7% higher than the current market price); and (3) the Trust receives $2.45, or 6.6% of the common stock’s value, as a premium. If the stock price remains unchanged, the option expires and there would be a 6.6% return for the three-month period. If the stock were to decline in price by 6.6% (i.e., decline to $34.70 per share), the option strategy would “break-even” from an economic perspective resulting in neither a gain nor a loss. If the stock were to climb to a price of $40 or above, the option would be exercised and the stock would return 7.7% coupled with the option premium received of 6.6% for a total return of 14.3%. Under this scenario, the Trust loses the benefit of any appreciation of the stock above $40, and thus is limited to a 14.3% total return. The premium from writing the call option serves to offset some of the unrealized loss on the stock in the event that the price of the stock declines, but if the stock were to decline more than 6.6% under this scenario, the Trust’s downside protection is eliminated and the stock could eventually become worthless.

Each Trust intends to write covered call options to varying degrees depending upon market conditions. Please refer to each Trust’s Schedule of Investments and the Notes to Financial Statements for details of written options.

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

What factors influenced performance?

Oil prices, after declining in the first half of the year, staged a strong recovery once signs emerged that the oil market was tighter than many believed. Global inventories declined at a time of the year when they typically rise, suggesting limited availability of near-term supply. However, energy stocks — after falling sharply when oil prices were weak in the first half — did not stage a rebound of equal magnitude in oil’s subsequent rally. In this environment, the Trust’s positions in more leveraged exploration and production (E&P) stocks, such as Anadarko Petroleum Corp. and Hess Corp., detracted from absolute performance.

There was a distinct performance differential between integrated energy companies and E&Ps during the year, with the former outperforming. In addition, international integrated companies outpaced their U.S. counterparts. With this as the backdrop, the Trust’s holdings in Royal Dutch Shell PLC and BP PLC were the largest contributors to absolute performance.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. The option overlay strategy had a positive impact on results.

Describe recent portfolio activity.

Early in the period, the investment adviser increased the Trust’s exposure to U.S. onshore energy services companies and funded the purchases by taking profits in certain E&P holdings. Later in the period, the investment adviser increased the Trust’s exposure to the integrated energy industry while reducing its allocation to certain U.S.-based E&P stocks. The latter shift included exiting the Trust’s position in Hess Corp. and reducing its weighting in EOG Resources, Inc.

Describe portfolio positioning at period end.

The E&P sector represented the Trust’s largest allocation, followed by the integrated, oil services, distribution, and refining & marketing industries, respectively. The investment adviser positioned the Trust with a higher-quality bias, focusing on companies with robust balance sheets and low costs of production.

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

The following discussion relates to the Trust’s relative performance based on the index cited above:

What factors influenced performance?

In sector terms, consumer discretionary was the prime contributor to relative performance, led by household durables and specialty retail holdings. Stock selection in energy and materials also added considerable value, as did holdings within the information technology (“IT”) sector. Conversely, utilities and financials detracted from performance.

In stock specifics, Lam Research Corp. and D.R. Horton, Inc. were top individual contributors. Lam performed very well, notably in the first half of the year, on the back of strong execution and growing demand for its products, driven by the build-out of 3D NAND capacity, for which the company is a key supplier. The stock was sold by the end of the reporting period as, in the investment adviser’s view, semiconductor capital expenditures are nearing peak levels and Lam’s valuation reflected the sustainability of above-normal demand trends. Homebuilders, including D.R. Horton, outperformed during the year on continued strength in single family housing demand, particularly among first-time, entry-level homebuyers. The investment adviser thinks that cyclical and secular drivers (particularly the return of the entry-level homebuyer) should support continued growth in housing markets for the foreseeable future and, hence, sustainable earnings per share growth that is not reflected in current homebuilder share prices.

Additional contributions came from an underweight to General Electric Co., as well as the position in Activision Blizzard, Inc.

Among the largest individual detractors in the period was Walgreens Boots Alliance. Early in the reporting period, sentiment for Walgreens’ shares was negatively affected by delays in the closing of its highly anticipated merger with peer Rite-Aid. Later, the stock underperformed on press reports that Amazon is evaluating entering the retail pharmacy market. The investment adviser ultimately sold the position on the view that the company’s over-reliance on front-of-the-store sales exposes it to potential ongoing sales and margin pressure.

Elsewhere, zero exposure to Amazon.com, Inc. and Facebook, Inc. proved disadvantageous.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. The Trust’s option writing strategy had a negative impact on performance during the reporting period.

Trust Information as of December 31, 2017 (continued) BlackRock Enhanced Capital and Income Fund, Inc.

Describe recent portfolio activity.

Due to a combination of portfolio trading activity and market movement during the 12-month period, the Trust’s exposure to the health care sector increased, with additions in utilities and materials as well. The largest reductions were in consumer staples and energy.

Describe portfolio positioning at period end.

From a positioning standpoint, as of period end, the investment adviser continues to favor financials, particularly banks, and is also focusing on stock-specific opportunities to capture growth tied to healthy U.S. consumers. These cyclical positions are balanced with strategic allocations to more stable growers in the health care and IT sectors. The investment adviser continues to underweight defensive stocks, as well as industrials.

The following discussion relates to the Trust’s relative performance based on the index cited above:

What factors influenced performance?

The largest contribution to performance for the 12-month period came from a combination of stock selection and allocation decisions within the health care sector. Notably, stock selection and an overweight to the health care providers & services industry and stock selection in pharmaceuticals added to relative performance. In energy, an underweight to U.S. integrated oil & gas operators and an overweight to their non-U.S.-domiciled peers proved beneficial within the oil, gas & consumable fuels industry. An underweight to the energy equipment & services industry also contributed. Lastly, a combination of stock selection within and an underweight to telecommunication services (“telecom”) contributed to relative performance, as did an underweight to the real estate sector.

The largest detractor from relative return derived from the portfolio’s cash position, as the period saw rising U.S. stock prices. Within utilities, a combination of stock selection within and an underweight to the electric utilities industry negatively impacted returns. In financials, stock selection in the insurance segment and an underweight to the diversified financial services industry detracted. At the industry level, stock selection within food & staples retailing was unfavorable.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. The Trust’s option writing strategy had a negative effect on performance.

Describe recent portfolio activity.

During the 12-month period, the Trust significantly boosted exposure to the health care sector. Holdings within telecom and utilities also were increased. Conversely, the Trust significantly reduced its holdings in the industrials sector. The Trust also reduced exposure to information technology (“IT”) and consumer discretionary.

Describe portfolio positioning at period end.

The Trust’s largest allocations were in the financials, health care and energy sectors. Relative to the benchmark, the Trust’s largest overweight positions were in the health care, IT and financials sectors. The Trust’s largest relative underweights were in the real estate, consumer discretionary and consumer staples segments.

The following discussion relates to the Trust’s relative performance based on the index cited above:

What factors influenced performance?

The Trust’s overweight to consumer staples detracted from returns, as did stock selection in the sector. In particular, exposure to tobacco stocks Imperial Brands PLC, Altria Group, Inc. and Philip Morris International, Inc. held back performance. Stock selection within materials and consumer discretionary also weighed on returns.

The leading contributor to relative performance during the period was stock selection in telecommunication services (“telecom”), notably within the diversified telecom services sub-industry, where a lack of exposure to AT&T, Inc. added to results. Positive stock selection within the financials sector contributed to returns, notably bank holdings Federal Bank Ltd. and Unicredit SpA. An underweight to utilities also boosted performance.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. The Trust’s options writing strategy detracted from returns.

Describe recent portfolio activity.

The Trust significantly increased exposure to consumer staples, with a focus on the tobacco industry, as well as to health care, where pharmaceuticals were favored. In contrast, the Trust eliminated exposure to energy and significantly reduced its holdings in financials, mainly banks.

The following discussion relates to the Trust’s relative performance based on the index cited above:

What factors influenced performance?

An overweight to and stock selection in health care detracted from relative performance, mainly driven by pharmaceuticals exposure. In addition, stock selection in consumer discretionary weighed on relative return, due largely to holdings within the internet and direct retail marketing industry. An overweight and stock selection in consumer staples also detracted, with tobacco holdings lagging the most. Lastly, an overweight to the materials sector constrained returns.

The leading contributor to relative performance during the period was positive stock selection within the financials sector, largely due to the Trust’s position in HDFC Bank Ltd., India’s second largest private bank. Favorable stock selection in information technology, notably within the software sector, also contributed to returns. Finally, stock selection in industrials and telecommunication services was additive.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. The Trust’s options writing strategy detracted from relative returns.

The following discussion relates to the Trust’s relative performance based on the index cited above:

What factors influenced performance?

Health care stocks produced strong absolute returns in 2017 amid the steady rally in the broader market. However, the sector lagged the headline indices somewhat due to investors’ preference for economically sensitive stocks.

The medical devices & supplies subsector was the sole detractor from relative performance due to underweights in the life sciences tools and health care supplies industries. However, positions in the health care equipment industry, including C.R. Bard, Inc. (which was acquired), Baxter International, Inc., Intuitive Surgical, Inc. and Stryker Corp., aided results.

The Trust generated outperformance in three out of four subsectors (health care providers & services, biotechnology and pharmaceuticals). The health care providers & services subsector had the largest positive effect on performance, largely due to the Trust’s overweight allocation to the managed care industry. Some of the key contributors in this area were UnitedHealth Group, Inc., Cigna Corp., Centene Corp., Aetna, Inc. and Anthem, Inc., all of which were bolstered by their of solid business results.

The biotechnology subsector also was a meaningful contributor to relative performance due to the investment adviser’s effective stock selection. Vertex Pharmaceuticals, Inc., which reported favorable results in its cystic fibrosis franchise earlier in the year, was a key contributor. Similarly, positions in Sarepta Therapeutics, Inc., AveXis, Inc. and Alnylam Pharmaceuticals, Inc., were notable contributors due to positive clinical developments. The Trust also benefited from an overweight position in Celgene Corp. for most of the year and then scaling back to an underweight stance before the company reported disappointing financial results in October.

In pharmaceuticals, underweight positions in Merck & Co., Inc. and Pfizer, Inc., combined with an out-of-benchmark position in AstraZeneca PLC, were the key drivers of the Trust’s positive performance.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. This strategy detracted from performance given the double-digit absolute return for health care stocks in 2017.

Describe portfolio positioning at period end.

The Trust continued to employ a bottom-up, fundamental investment process in an effort to construct a balanced, diversified portfolio of health care stocks. The investment adviser continued to look for companies that can benefit from the aging demographics in both developed and developing countries, as well as those participating in the innovation occurring in the medical technology.

What factors influenced performance?

The Trust’s allocation to the mining sector made a positive contribution to absolute returns in 2017. Economic data from China was better than expected, and the country’s measures to remove excess capacity in a number of industries was supportive for commodity prices such as zinc, where Chinese production fell year-over-year. Capacity rationalization, combined with solid demand and supply constraints stemming from the underinvestment in new mines in recent years, provided a highly favorable backdrop for the market. Base metals experienced the best performance, with copper and zinc moving to four- and ten-year highs, respectively. Precious metals prices also posted positive returns amid U.S. dollar weakness. While the price of iron ore declined, it remained meaningfully above analysts’ consensus and considerably higher than the lows of December 2015. The iron ore price, at these levels, supported healthy profit margins for mining companies. In this environment, the Trust’s holdings in Glencore PLC, Rio Tinto PLC and Vale SA all contributed to absolute returns.

The sandalwood producer Quintis Ltd. was the largest detractor from absolute performance. The company was the focus of a short seller report in March 2017, and in May it announced that it had lost a contract. While the contract was for a relatively small amount of product, the loss highlighted an internal control issue and raised concerns about the company’s management practices. Quintis later entered a voluntary trading halt and announced it was in discussions with multiple parties regarding debt and equity options.

The exploration & production company (“E&P”) Anadarko Petroleum Corp., which was negatively affected by the broader sell-off in energy stocks during the first half of the period, also detracted from returns. In addition, the company was linked to two operational incidents with fatalities. The Trust exited the position in November.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. The option overlay strategy had an adverse effect on results at a time of positive performance for the overall sector.

Describe recent portfolio activity.

The investment adviser increased the Trust’s weighting in the mining industry while taking profits in certain agriculture stocks that had performed well earlier in the year. It also rotated its energy holdings by exiting the E&P stocks Anadarko Petroleum Corp. and Hess Corp. and adding to positions in the integrated energy companies Chevron Corp. and Exxon Corp.

The battery-materials space (lithium and cobalt, and to a lesser extent, nickel and copper) grew in prominence in 2017. Investors’ excitement about the transition to electric vehicles mounted as countries stepped up their regulatory support efforts. China, for example, announced plans to introduce a ban on vehicles powered by fossil fuels. The shift toward electric vehicles led to an improving demand outlook for the related commodities. Accordingly, the investment adviser continued to seek opportunities in this area.

Trust Information as of December 31, 2017 BlackRock Science and Technology Trust

Investment Objective

BlackRock Science and Technology Trust’s (BST) (the “Trust”) investment objective is to provide income and total return through a combination of current income, current gains and long-term capital appreciation. The Trust seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its total assets in equity securities of science and technology companies. The Trust seeks to pursue this goal primarily by investing in a portfolio of equity securities and utilizing an option over-writing strategy in an effort to seek total return performance and enhance distributions.

The following discussion relates to the Trust’s relative performance based on the index cited above:

What factors influenced performance?

Positive contributions to the Trust’s relative performance were led by positions within the software & services group. These included mobile payment company Square Inc., video game publishers Take-Two Interactive Software, Inc., Activision Blizzard, Inc. and Nintendo Co. Ltd., and software engineering firm Altair Engineering. E-commerce holdings within the internet software & services industry also added to performance, including Chinese ecommerce giants Tencent Holdings Ltd. and Alibaba Group Holding Ltd., as well as Shopify, Inc. (Canada) and MercadoLibre, Inc. (Argentina). Positioning within semiconductor & semiconductor equipment boosted performance as well, led by SOITEC, STMicroelectronics NV, Ulvac, Inc. and LAM Research Corp.

Conversely, within the technology hardware & equipment industry group, the Trust’s underweights to consumer product firms Apple, Inc. and Samsung Electronics Co. Ltd., combined with overweight positions in handset component provider Sunny Optical Technology Co. Ltd. and chipmaker Advanced Micro Devices, Inc., detracted from performance. Other detractors included Tesla, Inc. in the automobile industry, RYB Education within consumer services and Jainpu Technology, Inc. in diversified financials.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. The Trust’s options writing strategy detracted from returns.

Describe recent portfolio activity.

The Trust added to positions in software & services, largely within the internet software & services sub-industry, while holdings in semiconductor & semiconductor equipment and technology hardware & equipment were slightly decreased.

Describe portfolio positioning at period end.

The Trust held its largest allocation within the software & services industry group, particularly idiosyncratic opportunities within the internet software & services and application software sub-industries. The portfolio also held large allocations in more stable cash flow businesses within the semiconductor & semiconductor equipment and technology hardware & equipment industries segments. Regionally, the Trust maintained most of its exposure in North America, followed by notable weights to the emerging markets and Europe.

Trust Information as of December 31, 2017 BlackRock Utilities, Infrastructure & Power Opportunities Trust

Investment Objective

BlackRock Utilities, Infrastructure & Power Opportunities Trust’s (BUI) (the “Trust”) investment objective is to provide total return through a combination of current income, current gains and long-term capital appreciation. The Trust seeks to achieve its investment objective by investing primarily in equity securities issued by companies that are engaged in the Utilities, Infrastructure and Power Opportunities business segments anywhere in the world and by utilizing an option writing (selling) strategy in an effort to seek total return performance and enhance distributions. The Trust considers the “Utilities” business segment to include products, technologies and services connected to the management, ownership, operation, construction, development or financing of facilities used to generate, transmit or distribute electricity, water, natural resources or telecommunications, the “Infrastructure” business segment to include companies that own or operate infrastructure assets or that are involved in the development, construction, distribution or financing of infrastructure assets and the “Power Opportunities” business segment to include companies with a significant involvement in, supporting, or necessary to renewable energy technology and development, alternative fuels, energy efficiency, automotive and sustainable mobility and technologies that enable or support the growth and adoption of new power and energy sources. Under normal circumstances, the Trust invests a substantial amount of its total assets in foreign issuers, issuers that primarily trade in a market located outside the United States or issuers that do a substantial amount of business outside the United States. The Trust may invest directly in such securities or synthetically through the use of derivatives.

On September 6, 2017, the Trust’s Board approved a proposal to change the name of BlackRock Utility and Infrastructure Trust to BlackRock Utilities, Infrastructure & Power Opportunities Trust. The Board also approved changes to certain of the Trust’s non-fundamental investment policies. Please refer to the Additional Information section. These changes became effective on November 27, 2017.

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

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

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

What factors influenced performance?

The largest contributor to performance was the Trust’s exposure to utilities. Utilities performed strongly during the period, as investors continued to seek higher-yielding equities. From an industry standpoint, stock selection in electric utilities and independent power & renewable electricity producers were the most noteworthy contributors to performance. Within the electric utilities industry, the Trust’s performance benefited from positions in Florida-based NextEra Energy, Inc. and Italian utility operator Enel SpA.

The largest detractor from performance was the Trust’s position in the energy sector, which has been negatively impacted by weak investor sentiment toward the sector. Specifically, the Trust’s position in the oil, gas, & consumable fuels industry notably detracted from performance, especially among midstream master limited partnerships Plains All American Pipeline, LP, Energy Transfer Partners, LP and Genesis Energy, LP.

The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced income returns while continuing to participate in the performance of the underlying equities. The Trust’s option writing strategy detracted from performance during the period.

Describe recent portfolio activity.

During the period, the Trust targeted companies that will benefit from the transition to a low carbon economy, both in the utilities sector and in other industries. The investment adviser believes that we have entered a period of significant disruption during which those companies that have embraced the transition to a lower carbon

world and begun to integrate renewable energy will outperform, while those that have been slow to make that transition will suffer from pressure on their business models. This has already begun in Europe, where renewable energy adoption is more advanced, but the trend is likely to affect the sector globally. The Trust’s evolution in its portfolio positioning addressed these structural shifts.

Describe portfolio positioning at period end.

The utilities sector accounted for approximately 62% of the Trust’s assets. The Trust had approximately 21% and 12% of its assets invested in the industrials and energy sectors, respectively, while the remainder was invested in other infrastructure- and power-related sectors.

Derivative Financial Instruments

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

  1. ORGANIZATION

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

Fund Name — BlackRock Energy and Resources Trust Herein Referred To As — BGR Organized — Delaware Non-diversified
BlackRock Enhanced Capital and Income Fund, Inc. CII Maryland Diversified
BlackRock Enhanced Equity Dividend Trust BDJ Delaware Diversified
BlackRock Enhanced Global Dividend Trust BOE Delaware Diversified
BlackRock Enhanced International Dividend Trust BGY Delaware Diversified
BlackRock Health Sciences Trust BME Delaware Diversified *
BlackRock Resources & Commodities Strategy Trust BCX Delaware Non-diversified
BlackRock Science and Technology Trust BST Delaware Non-diversified
BlackRock Utilities, Infrastructure & Power Opportunities
Trust BUI Delaware Diversified *
  • The Trust’s classification changed from non-diversified to diversified during the reporting period.

The Board of Directors and Boards of Trustees of the Trusts are collectively referred to throughout this report as the “Board of Trustees” or 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 closed-end funds referred to as the Closed-End Complex.

Basis of Consolidation: The accompanying consolidated financial statements of BCX include the account of BlackRock Cayman Resources & Commodities Strategy Fund, Ltd. (the “Subsidiary”), which is a wholly-owned subsidiary of BCX and primarily invests in commodity-related instruments. The Subsidiary enables BCX to hold these commodity-related instruments and other derivatives and satisfy regulated investment company tax requirements. BCX may invest up to 25% of its total assets in the Subsidiary. Intercompany accounts and transactions, if any, have been eliminated. During the year ended December 31, 2017, there were no transactions in the Subsidiary. The Subsidiary is subject to the same investment policies and restrictions that apply to BCX, except that the Subsidiary may invest without limitation in commodity-related instruments.

  1. 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 entered into (the “trade dates”). Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income are recorded on the ex-dividend date. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Trusts are informed of the ex-dividend date. Under the applicable foreign tax laws, a withholding tax at various rates may be imposed on capital gains, dividends and interest. Upon notification from issuers, some of the dividend income received from a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain. Interest income, including amortization and accretion of premiums and discounts on debt securities, are recognized on an accrual basis.

Foreign Currency Translation: Each Trust’s 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 portion of the results of operations arising as a result of changes in the exchange rates from the changes in the market prices of investments held or sold 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., futures contracts, forward foreign currency exchange contracts and options written) 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. Doing so allows the investment 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.

N OTES TO F INANCIAL S TATEMENTS 109

Notes to Financial Statements (continued)

Distributions: Distributions paid by the Trusts are recorded on the ex-dividend date. Subject to the Trusts’ level distribution plan, the Trusts intend to make monthly cash distributions to shareholders, which may consist of net investment income, net options premium and net realized and unrealized gains on investments and/or return of capital.

Portions of return of capital distributions under U.S. GAAP may be taxed at ordinary income rates.

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 Trust’s current and accumulated earnings and profits, which are measured on a tax basis, will constitute a non-taxable return of capital. Realized net capital gains can be offset by capital losses carried forward from prior years. However, certain Trusts have capital loss carryforwards from pre-2012 tax years that offset realized net capital gains but do not offset current earnings and profits. Consequently, if distributions in any tax year are less than a Trust’s current earnings and profits but greater than net investment income and net realized capital gains (taxable income), distributions in excess of taxable income are not treated as non-taxable return of capital, but rather may be taxable to shareholders at ordinary income rates. Under certain circumstances, taxable excess distributions could be significant. See Note 8, Income Tax Information, for the tax character of each Trust’s distributions paid during the period.

Net income and realized gains from investments held by the Subsidiary are treated as ordinary income for tax purposes. If a net loss is realized by the Subsidiary in any taxable year, the loss will generally not be available to offset BCX’s ordinary income and/or capital gains for that year.

Deferred Compensation Plan: Under the Deferred Compensation Plan (the “Plan”) approved by each Trust’s Board, the independent Trustees (“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 other BlackRock Closed-End Funds 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 other BlackRock Closed-End Funds.

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

Recent Accounting Standards: In November 2016, the Financial Accounting Standards Board issued Accounting Standards Update “Restricted Cash” which will require entities to include the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the beginning and ending cash balances in the Statements of Cash Flows. The guidance will be applied retrospectively and is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. Management is evaluating the impact, if any, of this guidance on the Trusts’ presentation in the Statements of Cash Flows.

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

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

Effective March 27, 2017, each Trust entered into a new custody arrangement with State Street Bank and Trust Co. Under current arrangements, the Trusts no longer earn credits on uninvested cash, and may incur charges on uninvested cash balances and overdrafts, subject to certain conditions.

Prior to March 27, 2017, the Trusts had an arrangement with their former custodian whereby credits were earned on uninvested cash balances, which could be used to reduce custody fees and/or overdraft charges. The Trusts could incur charges on certain uninvested cash balances and overdrafts, subject to certain conditions.

  1. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

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

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

• Equity investments traded on a recognized securities exchange are valued at the official closing price each day, if available. For equity investments traded on more than one exchange, the official closing price on the exchange where the stock is primarily traded is used. 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.

• Generally, trading in foreign instruments is substantially completed each day at various times prior to the close of trading on the NYSE. Occasionally, events affecting the values of such instruments may occur between the foreign market close and the close of trading on the NYSE that may not be reflected in the computation of the Trusts’ net assets. Each business day, the Trusts use a pricing service to assist with the valuation of certain foreign exchange-traded equity securities and foreign exchange-traded and over-the-counter (“OTC”) options (the “Systematic Fair Value Price”). Using current market factors, the Systematic Fair Value Price is designed to value such foreign securities and foreign options at fair value as of the close of trading on the NYSE, which follows the close of the local markets.

110 2017 B LACK R OCK A NNUAL R EPORT TO S HAREHOLDERS

Notes to Financial Statements (continued)

• Fixed-income securities for which market quotations are readily available are generally valued using the last available bid prices 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), 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 are valued at net asset value (“NAV”) each business day.

• The Trusts value their investment in SL Liquidity Series, LLC, Money Market Series (the “Money Market Series”) at fair value, which is ordinarily based upon their pro rata ownership in the underlying fund’s net assets. The Money Market Series seeks current income consistent with maintaining liquidity and preserving capital. Although the Money Market Series is not registered under the 1940 Act, its investments may follow the parameters of investments by a money market fund that is subject to Rule 2a-7 under the 1940 Act.

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

• 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. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available.

• 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 day’s price will be used, unless it is determined that the prior day’s price no longer reflects the fair value of the option. 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.

If events (e.g., a company announcement, market volatility or a natural disaster) occur that are expected to materially affect the value of such investments, or in the event that the application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, or its delegate, in accordance with a policy approved by the Board as reflecting fair value (“Fair Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee will include market approach, income approach and cost approach. Valuation techniques such as discounted cash flow, use of market comparables and matrix pricing are types of valuation approaches and are typically used in determining fair value. When determining the price for Fair Valued Investments, the Global Valuation Committee, or its delegate, seeks to determine the price that each Trust might reasonably expect to receive or pay from the current sale or purchase of that asset or liability in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the Global Valuation Committee, or its delegate, deems relevant and consistent with the principles of fair value measurement.

The Global Valuation Committee, or its delegate, employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of each Trust’s pricing vendors, regular reviews of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices and large movements in market values and reviews of any market related activity. The pricing of all Fair Valued Investments is subsequently reported to the Board or a committee thereof on a quarterly basis. As a result of the inherent uncertainty in valuation of these investments, the fair values may differ from the values that would have been used had an active market existed.

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 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 Company’s
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. Valuation techniques such as an option pricing model (“OPM”), a probability weighted expected return model (“PWERM”) or a hybrid of those techniques are used in allocating

N OTES TO F INANCIAL S TATEMENTS 111

Notes to Financial Statements (continued)

enterprise value of the company, as deemed appropriate under the circumstances. The use of OPM and PWERM 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 as 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 investments and derivative financial instruments. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial statement purposes as follows:

• Level 1 — Unadjusted price quotations in active markets/exchanges for identical assets or liabilities that each Trust has the ability to access

• Level 2 — Other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market–corroborated inputs)

• Level 3 — Unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including each Trust’s own assumptions used in determining the fair value of investments and derivative financial instruments)

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. 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. There may not be a secondary market, and/or there are a limited number of investors. Level 3 investments may also be adjusted to reflect illiquidity and/or non-transferability, with the amount of such discount estimated by the Global Valuation Committee in the absence of market information.

Changes in valuation techniques may result in transfers into or out of an assigned level within the hierarchy. In accordance with each Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of a value determined for investments and derivative financial instruments is based on the pricing transparency of the investments and derivative financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

As of December 31, 2017, certain investments of BME, BCX and BST were valued using NAV or its equivalent as no quoted market value is available and therefore have been excluded from the fair value hierarchy.

  1. SECURITIES AND OTHER INVESTMENTS

Preferred Stocks: Preferred stock has a preference over common stock in liquidation (and generally in receiving dividends as well), but is subordinated to the liabilities of the issuer in all respects. As a general rule, the market value of preferred stock with a fixed dividend rate and no conversion element varies inversely with interest rates and perceived credit risk, while the market price of convertible preferred stock generally also reflects some element of conversion value. Because preferred stock is junior to debt securities and other obligations of the issuer, deterioration in the credit quality of the issuer will cause greater changes in the value of a preferred stock than in a more senior debt security with similar stated yield characteristics. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Securities Lending: Certain Trusts may lend their securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Trusts collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. Government. The initial collateral received by each Trust is required to have a value of at least 102% of the current value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current market value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Trust and any additional required collateral is delivered to the Trust, or excess collateral returned by the Trust, on the next business day. During the term of the loan, the Trusts are entitled to all distributions made on or in respect of the loaned securities, but do not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

The market value of any securities on loan, all of which were classified as common stocks in the Trusts’ Schedules of Investments, and the value of any related collateral are shown separately in the Statements of Assets and Liabilities as a component of investments at value-unaffiliated, and collateral on securities loaned at value, respectively. As of period end, any securities on loan were collateralized by cash and/or U.S. Government obligations. Cash collateral invested by the securities lending agent, BlackRock Investment Management, LLC (“BIM”), if any, is disclosed in the Schedules of Investments.

Securities lending transactions are entered into by the Trusts under Master Securities Lending Agreements (each, an “MSLA”), which provide the right, in the event of default (including bankruptcy or insolvency), for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Trusts, as lender, would offset the market value of the collateral received against the market value of the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, absent an event of default, the borrower can resell or re-pledge the loaned securities, and a Trust can reinvest cash collateral received in connection with loaned securities. Upon an event of default, the parties’ obligations to return the securities or collateral to the other party are

112 2017 B LACK R OCK A NNUAL R EPORT TO S HAREHOLDERS

Notes to Financial Statements (continued)

extinguished, and the parties can resell or re-pledge the loaned securities or the collateral received in connection with the loaned securities in order to satisfy the defaulting party’s net payment obligation for all transactions under the MSLA. The defaulting party remains liable for any deficiency.

As of period end, the following table is a summary of the Trusts’ securities lending agreements by counterparty which are subject to offset under an MSLA:

(a) Cash collateral with a value of $120,900, $485,343 and $3,497,229 for BME, BCX and BST, respectively, has been received in connection with securities lending agreements. Collateral received in excess of the value of securities loaned from the individual counterparty is not shown for financial reporting purposes in the table above.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Trusts benefit from a borrower default indemnity provided by BIM. BIM’s indemnity allows for full replacement of the securities loaned if the collateral received does not cover the value on the securities loaned in the event of borrower default. Each Trust could incur a loss if the value of an investment purchased with cash collateral falls below the market value of loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received.

  1. 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), changes in the value of equity securities (equity risk) or foreign currencies (foreign currency exchange rate risk).

Futures contracts are agreements between the Trusts and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and on a specified date. Depending on the terms of a contract, it is settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash amount on the settlement date. Upon entering into a futures contract, the Trusts are required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on a contract’s size and risk profile. The initial margin deposit must then be maintained at an established level over the life of the contract.

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

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 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

N OTES TO F INANCIAL S TATEMENTS 113

Notes to Financial Statements (continued)

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.

Options: Certain Trusts 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 subject to being called by the option counterparty. When the Trusts write a put option, such option is covered by cash in an amount sufficient to cover the obligation. As of period end, the value of portfolio securities subject to covered call options written was as follows:

BGR — $ 160,032,735 $ 359,086,742 $ 924,576,076 $ 401,410,854 $ 311,661,172 $ 94,379,211 $ 346,441,742 $ 193,650,191 $ 113,375,126

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 it otherwise would not, or at a price different from the current market value.

Master Netting Arrangements: In order to define their contractual rights and to secure rights that will help them mitigate their counterparty risk, the Trusts may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement with their counterparties. An ISDA Master Agreement is a bilateral agreement between each 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, each 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. Bankruptcy or insolvency laws of a particular jurisdiction may restrict or prohibit the right of offset in bankruptcy, insolvency or other events.

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 Trusts 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 on 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 their counterparties are not fully collateralized, they bear 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, they bear 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.

  1. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

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

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

For such services, each Trust, except BCX and BST, pays the Manager a monthly fee at the following annual rates:

Average weekly value of each Trust’s net assets:
BGR 1.20 %
BDJ 0.80
BOE 1.00
BME 1.00

114 2017 B LACK R OCK A NNUAL R EPORT TO S HAREHOLDERS

Notes to Financial Statements (continued)

Average daily value of each Trust’s net assets:
CII 0.85 %
BGY 1.00
BUI 1.00

For such services, BCX pays the Manager a monthly fee of 1.00% of the sum of the average daily value of the net assets of the Trust (excluding the value of the Trust’s interest in its Subsidiary) and the average daily value of the net assets of its Subsidiary, which fee is allocated pro rata between the Trust and its Subsidiary based on the average daily value of their respective net assets (excluding, in the case of the Trust, the value of the Trust’s interest in its Subsidiary).

For such services, BST pays the Manager a monthly fee at an annual rate equal to 1.00% of the average daily value of the Trust’s managed assets. For purposes of calculating this fee, “managed assets” means the total assets of the Trust (including any assets attributable to money borrowed for investment purposes) minus the sum of its accrued liabilities (other than money borrowed for investment purposes).

With respect to BGR, BOE, BGY, BCX and BUI, the Manager entered into separate sub-advisory agreements with BlackRock International Limited (“BIL”), an affiliate of the Manager. The Manager pays BIL, for services it provides, a monthly fee that is a percentage of the investment advisory fees paid by each Trust to the Manager.

The Manager provides investment management and other services to BCX’s Subsidiary. The Manager does not receive separate compensation from the Subsidiary for providing investment management or administrative services. However, BCX pays the Manager based on the Trust’s net assets which includes the assets of the Subsidiary.

Distribution Fees: BME has entered into a Distribution Agreement with BlackRock Investments, LLC (“BRIL”), an affiliate of the Manager, to provide for distribution of BME common shares on a reasonable best efforts basis through an equity shelf offering (a “Shelf Offering”) (the “Distribution Agreement”). Pursuant to the Distribution Agreement, BME will compensate BRIL with respect to sales of common shares at a commission rate of 1.00% of the gross proceeds of the sale of BME’s common shares and a portion of such commission is re-allowed to broker-dealers engaged by BRIL. The commissions retained by BRIL during the year ended December 31, 2017 amounted to $42,271.

Expense Limitations, Waivers, and Reimbursements: The Manager has contractually agreed to waive a portion of the investment advisory fees on BST as a percentage of its average daily managed assets as follows:

0.20 % December 31, 2018
0.15 December 31, 2019
0.10 December 31, 2020
0.05 December 31, 2021

Effective July 1, 2017, the Manager voluntarily agreed to waive a portion of the investment advisory fees on the following Trusts as a percentage of their average weekly net assets as follows:

BGR 0.150
BOE 0.100
BUI 0.025

Prior to July 1, 2017, the Manager voluntarily agreed to waive a portion of the investment advisory fees on the following Trusts as a percentage of their average weekly net assets as follows:

BGR 0.10
BOE 0.05

With respect to BGY, the Manager has voluntarily agreed to waive a portion of its investment advisory fees equal to the annual rate of 0.10% of BGY’s average daily net assets.

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

For the year ended December 31, 2017, the investment advisory fees waived, which are included in fees waived and/or reimbursed by the Manager in the Statements of Operations, were as follows:

BGR 556,737
BOE 738,124
BGY 738,989
BST 1,102,320
BUI 45,208

N OTES TO F INANCIAL S TATEMENTS 115

Notes to Financial Statements (continued)

With respect to each Trust, the Manager voluntarily 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”). These amounts are included in fees waived and/or reimbursed by the Manager in the Statements of Operations. For the year ended December 31, 2017, the amounts waived were as follows:

Amount Waived
BGR $ 4,448
CII 8,615
BDJ 5,748
BOE 17,704
BGY 15,145
BME 7,086
BCX 10,076
BST 1,739
BUI 3,652

The Manager contractually agreed to waive its investment advisory fee with respect to any portion of each Trust’s assets invested in affiliated equity and fixed-income mutual funds and affiliated exchange-traded funds that have a contractual management fee through June 30, 2018. 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. These amounts are included in fees waived and/or reimbursed by the Manager in the Statements of Operations. For the year ended December 31, 2017, BOE waived $9,522 in investment advisory fees pursuant to these arrangements.

Securities Lending: The U.S. Securities and Exchange Commission (“SEC”) has issued an exemptive order which permits BIM, an affiliate of the Manager, to serve as securities lending agent for the Trusts, subject to applicable conditions. As securities lending agent, BIM bears all operational costs directly related to securities lending. The Trusts are responsible for expenses in connection with the investment of cash collateral received for securities on loan (the “collateral investment expenses”). The cash collateral is invested in a private investment company managed by the Manager or its affiliates. However, BIM has agreed to cap the collateral investment expenses of the private investment company to an annual rate of 0.04%. The investment adviser to the private investment company will not charge any advisory fees with respect to shares purchased by the Trusts. The private investment company in which the cash collateral has been invested may, under certain circumstances, impose a liquidity fee of up to 2% of the value withdrawn or temporarily restrict withdrawals for up to 10 business days during a 90 day period, in the event that the private investment company’s weekly liquid assets fall below certain thresholds.

Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment expenses. Each Trust retains a portion of securities lending income and remits a remaining portion to BIM as compensation for its services as securities lending agent. Pursuant to a securities lending agreement, BIM may lend securities only when the difference between the borrower rebate rate and the risk free rate exceeds a certain level (such securities, the “specials only securities”).

Pursuant to such agreement, each Trust retains 80% of securities lending income. In addition, commencing the business day following the date that the aggregate securities lending income earned across the Closed-End Complex in a calendar year exceeds the breakpoint dollar threshold applicable in the given year as set forth in the securities lending agreement, each Trust, pursuant to the securities lending agreement, will retain for the remainder of the calendar year securities lending income in an amount equal to 85% of securities lending income.

The share of securities lending income earned by each Trust is shown as securities lending income — affiliated — net in the Statements of Operations. For the year ended December 31, 2017, each Trust paid BIM the following amounts for securities lending agent services:

BGR 5,781
CII 287
BDJ 377
BOE 8,140
BGY 125
BME 444
BCX 28,901
BST 24,527
BUI 969

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

Other Transactions: During the year ended December 31, 2017, BOE and BGY received reimbursements of $393,604 and $259,510, respectively, from an affiliate, which is shown as payments by affiliates in the Statements of Operations, related to the reimbursement of transaction costs.

  1. INCOME TAX INFORMATION

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

Each Trust files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on each Trust’ U.S. federal tax returns generally remains open for each of the three years ended December 31, 2017, the period ended December 31, 2014 and the year ended October 31, 2014 with the exception of BST. The statutes of limitations on BST’s U.S. federal tax returns remains open for each of the three years ended December 31, 2017 and the period ended December 31, 2014. The statutes of limitations on each Trust’ 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 December 31, 2017, 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.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. As of period end, the following permanent differences attributable to foreign currency transactions, the sale of stock of passive foreign investment companies, the characterization of expenses, reimbursement of transaction costs, income recognized from investments in partnerships and the expiration of capital loss carryforwards were reclassified to the following accounts:

  1. 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.

The Trusts may be exposed to additional risks when reinvesting cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00 and which may be subject to redemption gates or liquidity fees under certain circumstances.

Valuation Risk: The market values of equities, such as common stocks and preferred securities or equity related investments, such as futures and options, may decline due to general market conditions which are not specifically related to a particular company. They may also decline due to factors which affect a particular industry or industries. A Trust may invest in illiquid investments and may experience difficulty in selling those investments in a timely manner at the price that they believe the investments are worth. Prices may fluctuate widely over short or extended periods in response to company, market or economic news. Markets also tend to move in cycles, with periods of rising and falling prices. This volatility may cause each Trust’s NAV to experience significant increases or decreases over short periods of time. If there is a general decline in the securities and other markets, the NAV of a Trust may lose value, regardless of the individual results of the securities and other instruments in which a Trust invests.

The price a Trust could receive upon the sale of any particular portfolio investment may differ from a Trust 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 Trust 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 Trust 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. 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.

A Trust’s risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain less the value of any collateral held by such Trust.

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 the Trusts deposit collateral with its counterparty to a written option.

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

Concentration Risk: As of period end, the Trusts listed below invested a significant portion of their assets in securities in the following sectors:

Energy BGR, BCX
Financials BDJ, BGY
Health Care BME
Information Technology CII, BST
Materials BCX
Utilities BUI

N OTES TO F INANCIAL S TATEMENTS 119

Notes to Financial Statements (continued)

Changes in economic conditions affecting such sectors would have a greater impact on the Trusts and could affect the value, income and/or liquidity of positions in such securities.

BOE invests a substantial amount of its assets in issuers located in a single country or a limited number of countries. When a Trust concentrates its investments in this manner, it assumes the risk that economic, political and social conditions in those countries may have a significant impact on its investment performance. Foreign issuers may not be subject to the same uniform accounting, auditing and financial reporting standards and practices as used in the United States. Foreign securities markets may also be less liquid, more volatile, and less subject to governmental supervision not typically associated with investing in U.S. securities. Investment percentages in specific countries are presented in the Schedules of Investments.

BGY and BCX invest a significant portion of their assets in securities of issuers located in Europe or with significant exposure to European issuers or countries. The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns in, or rising government debt levels of, several European countries. These events may spread to other countries in Europe and may affect the value and liquidity of certain of the Trusts’ investments.

The United Kingdom voted on June 23, 2016 to withdraw from the European Union, which may introduce significant new uncertainties and instability in the financial markets across Europe.

  1. CAPITAL SHARE TRANSACTIONS

Each Trust is authorized to issue an unlimited numbers of shares, with the exception of CII, all of which were initially classified as Common Shares. CII is authorized to issue 200 million Common Shares. The par value for each Trust’s Common Shares is $0.001, except for CII, which is $0.10. The Board is authorized, however, to reclassify any unissued Common Shares to Preferred Shares without the approval of Common Shareholders.

For the periods shown, shares issued and outstanding increased by the following amounts as a result of shares issued through the Shelf Offering:

12/31/17 12/31/16
BME 601,804 363,708

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

12/31/17 12/31/16
BME 47,676 63,264
BUI 33,776 —

For the year ended December 31, 2017, for BGR and CII and December 31, 2016, for BGR, CII, BDJ, BOE, BGY, BCX, BST and BUI, shares issued and outstanding remained constant.

On June 9, 2016, BME filed a final prospectus with the SEC allowing it to issue an additional 2,500,000 Common Shares through a Shelf Offering. Under the Shelf Offering, BME, subject to market conditions, may raise additional equity capital from time to time in varying amounts and utilizing various offering methods at a net price at or above BME’s NAV per Common Share (calculated within 48 hours of pricing). As of period end, 1,534,488 Common Shares remain available for issuance under the Shelf Offering. From August 12, 2015 to June 9, 2016, BME was authorized to issue 453,000 Common Shares under a previous Shelf Offering. See Additional Information — Shelf Offering Program for additional information about the Shelf Offering.

Initial costs incurred by BME in connection with its shelf offering are recorded “Deferred offering costs” on the Statements of Assets and Liabilities. As shares are sold, a portion of the costs attributable to the shares sold will be charged against paid-in-capital. Any remaining deferred charges at the end of the shelf offering period will be charged to expense. Any subsequent costs incurred to keep the filing active will be charged to expense as incurred.

The Board previously approved each Trust’s participation in an open market share repurchase program that allowed each Trust to purchase, at prevailing market prices, up to 5% of its common shares outstanding as of the close of business on October 28, 2016 through November 30, 2017, subject to certain conditions. On September 6, 2017, the Board approved a renewal of this program. Commencing December 1, 2017, each Trust may purchase through November 30, 2018, up to 5% of its common shares outstanding as of the close of business on November 30, 2017, subject to certain conditions. There is no assurance that the Trusts will purchase shares in any particular amounts. The shares repurchased during the year ended December 31, 2017 are as follows:

BlackRock Energy and Resources Trust, BlackRock Enhanced Equity Dividend Trust, BlackRock Enhanced Global Dividend Trust, BlackRock Enhanced International Dividend Trust, BlackRock Health Sciences Trust, BlackRock Resources & Commodities Strategy Trust, BlackRock Science and Technology Trust, BlackRock Utilities, Infrastructure & Power Opportunities Trust, and the Shareholders and Board of Directors of BlackRock Enhanced Capital and Income Fund, Inc.:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of BlackRock Energy and Resources Trust, BlackRock Enhanced Capital and Income Fund, Inc., BlackRock Enhanced Equity Dividend Trust, BlackRock Enhanced Global Dividend Trust (formerly known as BlackRock Global Opportunities Equity Trust), BlackRock Enhanced International Dividend Trust (formerly known as BlackRock International Growth and Income Trust), BlackRock Health Sciences Trust, BlackRock Science and Technology Trust and BlackRock Utilities, Infrastructure & Power Opportunities Trust (formerly known as BlackRock Utility and Infrastructure Trust), as of December 31, 2017, the related statements of operations and cash flows for the year then ended, the statements of changes net assets for each of the two years in the period then ended, the financial highlights for each of the periods presented, and the related notes. We have also audited the consolidated statement of assets and liabilities, including the consolidated schedule of investments, of BlackRock Resources & Commodities Strategy Trust (collectively with BlackRock Energy and Resources Trust, BlackRock Enhanced Capital and Income Fund, Inc., BlackRock Enhanced Equity Dividend Trust, BlackRock Enhanced Global Dividend Trust, BlackRock Enhanced International Dividend Trust, BlackRock Health Sciences Trust, BlackRock Science and Technology Trust and BlackRock Utilities, Infrastructure & Power Opportunities Trust, the “Trusts”), as of December 31, 2017, the related consolidated statements of operations and cash flows for the year then ended, the consolidated statements of changes in net assets for each of the two years in the period then ended and the consolidated financial highlights for each of the periods presented. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Trusts as of December 31, 2017, and the results of their operations and their cash flows for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Trusts’ management. Our responsibility is to express an opinion on the Trusts’ financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Trusts are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Trusts’ internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of December 31, 2017, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion.

I MPORTANT T AX I NFORMATION 123

Automatic Dividend Reinvestment Plans

Pursuant to each Trust’s Dividend Reinvestment Plan (the “Reinvestment Plan”), Common Shareholders are automatically enrolled, to have all distributions of dividends and capital gains and other distributions reinvested by Computershare Trust Company, N.A. (the “Reinvestment Plan Agent”) in the respective Trust’s Common Shares pursuant to the Reinvestment Plan. Shareholders who do not participate in the Reinvestment Plan will receive all distributions in cash paid by check and mailed directly to the shareholders of record (or if the shares are held in street name or other nominee name, then to the nominee) by the Reinvestment Plan Agent, which serves as agent for the shareholders in administering the Reinvestment Plan.

After the Trusts declare a dividend or determine to make a capital gain or other distribution, the Reinvestment Plan Agent will acquire shares for the participants’ accounts, depending upon the following circumstances, either (i) through receipt of unissued but authorized shares from the Trust (“newly issued shares”) or (ii) by purchase of outstanding shares on the open market or on the Trust’s primary exchange (“open market purchases”). If, on the dividend payment date, the net asset value per share (“NAV”) is equal to or less than the market price per share plus estimated brokerage commissions (such condition often referred to as a “market premium”), the Reinvestment Plan Agent will invest the dividend amount in newly issued shares acquired on behalf of the participants. The number of newly issued shares to be credited to each participant’s account will be determined by dividing the dollar amount of the dividend by the NAV on the date the shares are issued. However, if the NAV is less than 95% of the market price on the dividend payment date, the dollar amount of the dividend will be divided by 95% of the market price on the dividend payment date. If, on the dividend payment date, the NAV is greater than the market price per share plus estimated brokerage commissions (such condition often referred to as a “market discount”), the Reinvestment Plan Agent will invest the dividend amount in shares acquired on behalf of the participants in open-market purchases. If the Reinvestment Plan Agent is unable to invest the full dividend amount in open market purchases, or if the market discount shifts to a market premium during the purchase period, the Reinvestment Plan Agent will invest any un-invested portion in newly issued shares. Investments in newly issued shares made in this manner would be made pursuant to the same process described above and the date of issue for such newly issued shares will substitute for the dividend payment date.

You may elect not to participate in the Reinvestment Plan and to receive all dividends in cash by contacting the Reinvestment Plan Agent, at the address set forth below.

Participation in the Reinvestment Plan is completely voluntary and may be terminated or resumed at any time without penalty by notice if received and processed by the Reinvestment Plan Agent prior to the dividend record date. Additionally, the Reinvestment Plan Agent seeks to process notices received after the record date but prior to the payable date and such notices often will become effective by the payable date. Where late notices are not processed by the applicable payable date, such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution.

The Reinvestment Plan Agent’s fees for the handling of the reinvestment of distributions will be paid by each Trust. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Reinvestment Plan Agent’s open market purchases in connection with the reinvestment of all distributions. The automatic reinvestment of all distributions will not relieve participants of any U.S. federal, state or local income tax that may be payable on such dividends or distributions.

Each Trust reserves the right to amend or terminate the Reinvestment Plan. There is no direct service charge to participants in the Reinvestment Plan; however, each Trust reserves the right to amend the Reinvestment Plan to include a service charge payable by the participants. Participants that request a sale of shares are subject to a $0.02 per share sold brokerage commission. All correspondence concerning the Reinvestment Plan should be directed to Computershare Trust Company, N.A. through the internet at http://www.computershare.com/blackrock, or in writing to Computershare, P.O. Box 505000, Louisville, KY 40233, Telephone: (800) 699-1236. Overnight correspondence should be directed to the Reinvestment Plan Agent at Computershare, 462 South 4 th Street, Suite 1600, Louisville, KY 40202.

Fund Certification

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

General Information

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

BME’s Statement of Additional Information includes addition information about its Board and is available, without charge upon request by calling 1-800-882-0052.

Except as described below, during the period there were no material changes in the Trusts’ investment objectives or policies or to the Trusts’ charters or by-laws that would delay or prevent a change of control of the Trusts that were not approved by the shareholders or in the principal risk factors associated with investment in the Trusts. Except as disclosed on page 127, there have been no changes in the persons who are primarily responsible for the day-to-day management of the Trusts’ portfolios.

On March 22, 2017, BOE’s and BGY’s Board approved changes to certain non-fundamental investment policies of each Trust.

Historically, under normal market conditions, BOE has been required to invest (i) at least 80% of its total assets in equity securities or indices or sectors of equity securities and (ii) at least 30% of its total assets at the time of investment in the equity securities of non-U.S. issuers. Under the new investment policy, under normal circumstances, the Trust is required to invest (i) at least 80% of its net assets in dividend-paying equity securities and (ii) at least 40% of its assets outside of the United States, unless market conditions are not deemed favorable by Trust management, in which case the Trust would invest at least 30% of its assets outside of the United States.

BOE has also historically intended to write covered put and call options with respect to approximately 45% to 65% of its total assets, with the expectation that such percentage would vary from time to time with market conditions. Under the new investment policy, the Trust intends to write covered put and call options with respect to approximately 30% to 45% of its total assets, although this percentage may vary from time to time with market conditions.

Finally, BOE has historically been permitted to invest in companies of any size market capitalization. While the new investment policy continues to permit this, the Trust intends to invest primarily in the securities of large capitalization companies.

In connection with these changes in certain non-fundamental policies, BOE’s Board approved a change to the Trust’s name from “BlackRock Global Opportunities Equity Trust” to “BlackRock Enhanced Global Dividend Trust” to reflect BOE’s new portfolio characteristics.

Historically, under normal market conditions, BGY has been required to invest at least 80% of its total assets in equity securities issued by non-U.S. companies. Under the new investment policy, under normal circumstances, the Trust will be required to invest at least 80% of its net assets in dividend-paying equity securities issued by non-U.S. companies.

BGY has also historically intended to write covered put and call options with respect to approximately 45% to 55% of its total assets, with the expectation that such percentage would vary from time to time with market conditions. Under the new investment policy, the Trust intends to write covered put and call options with respect to approximately 30% to 45% of its total assets, although this percentage may vary from time to time with market conditions.

Finally, BGY has historically been permitted to invest in companies of any size market capitalization. While the new investment policy continues to permit this, it specifies that the Trust intends to invest primarily in the securities of large capitalization companies.

Additional Information (continued)

In connection with these changes in certain non-fundamental policies, BGY’s Board approved a change to the Trust’s name from “BlackRock International Growth & Income Trust” to “BlackRock Enhanced International Dividend Trust” to reflect the Trust’s new portfolio characteristics.

An affiliate has reimbursed BOE and BGY for certain transaction costs associated with repositioning of the fund investments described above.

The approved changes to BGY and BOE will not alter either Trust’s investment objective. Each Trust continues to trade on the NYSE under its current ticker symbol.

On October 28, 2016, CII announced that it had divided its Board into three classes, with one class standing for election each year, and had adopted a voting standard of a majority of the outstanding shares for the election of directors in a contested election.

On October 28, 2016, BGR, BDJ, BOE, BGY, BME, BCX, BST and BUI announced that they had adopted a voting standard of a majority of the outstanding shares for the election of directors in a contested election.

On September 6, 2017, BUI’s Board approved changes to certain non-fundamental investment policies of the Trust.

Historically, under normal market conditions, BUI has been required to invest at least 80% of its total assets in equity securities issued by companies that are engaged in the Utilities or Infrastructure business segments. Under the new investment policy, under normal market conditions, the Trust will invest at least 80% of its total assets in equity securities issued by companies that are engaged in the Utilities, Infrastructure and Power Opportunities business segments.

In connection with these changes in certain non-fundamental policies, BUI’s Board approved a change to the Trust’s name from BlackRock Utility and Infrastructure Trust to BlackRock Utilities, Infrastructure & Power Opportunities Trust to reflect BUI’s new portfolio characteristics.

The approved changes to BUI will not alter the Trust’s investment objective. The Trust continues to trade on the NYSE under its current ticker symbol.

To enroll in electronic delivery:

Shareholders Who Hold Accounts with Investment Advisers, Banks or Brokerages:

Householding

The Trusts will mail only one copy of shareholder documents, annual and semi-annual reports and proxy statements, to shareholders with multiple accounts at the same address. This practice is commonly called “householding” and is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise.

Additional Information (continued)

Availability of Trust Updates

BlackRock will update performance and certain other data for the Trusts on a monthly basis on its website in the “Closed-end Funds” section of http://www.blackrock.com as well as certain other material information as necessary from time to time. Investors and others are advised to check the website for updated performance information and the release of other material information about the Trusts. This reference to BlackRock’s website is intended to allow investors public access to information regarding the Trusts and does not, and is not intended to, incorporate BlackRock’s website in this report.

Shelf Offering Program

From time-to-time, each Trust may seek to raise additional equity capital through an equity shelf program (a “Shelf Offering”). In a Shelf Offering, a Trust may, subject to market conditions, raise additional equity capital by issuing new Common Shares from time to time in varying amounts at a net price at or above the Trust’s net asset value (“NAV”) per Common Share (calculated within 48 hours of pricing). While any such Shelf Offering may allow a Trust to pursue additional investment opportunities without the need to sell existing portfolio investments, it could also entail risks — including that the issuance of additional Common Shares may limit the extent to which the Common Shares are able to trade at a premium to NAV in the secondary market.

BME has filed a final prospectus with the SEC in connection with its Shelf Offering. This report and the prospectus of BME are not offers to sell BME Common Shares or solicitations of an offer to buy BME Common Shares in any jurisdiction where such offers or sales are not permitted. The prospectus of BME contains important information about the Trust, including its investment objective, risks, charges and expenses. Investors are urged to read the prospectus of BME carefully and in its entirety before investing. Copies of the final prospectus for BME can be obtained from BlackRock at http://www.blackrock.com .

Dividend Policy

Each Trust’s dividend policy is to distribute all or a portion of its net investment income to its shareholders on a monthly basis. In order to provide shareholders with a more stable level of dividend distributions, the distributions paid by the Trusts for any particular month may be more or less than the amount of net investment income earned by the Trusts during such month. The portion of distributions that exceeds a Trust’s current and accumulated earnings and profits, which are measured on a tax basis, will constitute a nontaxable return of capital. Distributions in excess of a Trust’s taxable income and net capital gains, but not in excess of a Trust’s earnings and profits, will be taxable to shareholders as ordinary income and will not constitute a nontaxable return of capital. The Trusts’ current accumulated but undistributed net investment income, if any, is disclosed in the Statements of Assets and Liabilities, which comprises part of the financial information included in this report.

Item 2 – Code of Ethics – The registrant (or the “Fund”) has adopted a code of ethics, as of the end of the period covered by this report, applicable to the registrant’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. During the period covered by this report, the code of ethics was amended to clarify an inconsistency as to whom persons covered by the code should report suspected violations of the code. The amendment clarifies that such reporting should be made to BlackRock Advisors, LLC’s (“Investment Adviser” or “BlackRock”) General Counsel, and retains the alternative option of anonymous reporting following “whistleblower” policies. Other non-material changes were also made in connection with this amendment. During the period covered by this report, there have been no waivers granted under the code of ethics. The registrant undertakes to provide a copy of the code of ethics to any person upon request, without charge, who calls 1-800-882-0052, option 4.

Item 3 – Audit Committee Financial Expert – The registrant’s board of directors (the “board of directors”), has determined that (i) the registrant has the following audit committee financial experts serving on its audit committee and (ii) each audit committee financial expert is independent:

Michael Castellano

Frank J. Fabozzi

W. Carl Kester

Catherine A. Lynch

Karen P. Robards

The registrant’s board of directors has determined that W. Carl Kester and Karen P. Robards qualify as financial experts pursuant to Item 3(c)(4) of Form N-CSR.

Prof. Kester has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. Prof. Kester has been involved in providing valuation and other financial consulting services to corporate clients since 1978. Prof. Kester’s financial consulting services present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the registrant’s financial statements.

Ms. Robards has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. Ms. Robards has been President of Robards & Company, a financial advisory firm, since 1987. Ms. Robards was formerly an investment banker for more than 10 years where she was responsible for evaluating and assessing the performance of companies based on their financial results. Ms. Robards has over 30 years of experience analyzing financial statements. She also is a member of the audit committee of one publicly held company and a non-profit organization.

Under applicable securities laws, a person determined to be an audit committee financial expert will not be deemed an “expert” for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert. The designation or identification as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification. The designation or identification of a person as an audit committee financial expert does not affect the duties, obligations, or liability of any other member of the audit committee or board of directors.

Item 4 – Principal Accountant Fees and Services

The following table presents fees billed by Deloitte & Touche LLP (“D&T”) in each of the last two fiscal years for the services rendered to the Fund:

Entity Name (a) Audit Fees — Current Fiscal Year End Previous Fiscal Year End (b) Audit-Related Fees 1 — Current Fiscal Year End Previous Fiscal Year End (c) Tax Fees 2 — Current Fiscal Year End Previous Fiscal Year End (d) All Other Fees — Current Fiscal Year End Previous Fiscal Year End
BlackRock Enhanced Global Dividend Trust $55,952 $57,822 $7,500 $0 $15,147 $15,147 $0 $0

The following table presents fees billed by D&T that were required to be approved by the registrant’s audit committee (the “Committee”) for services that relate directly to the operations or financial reporting of the Fund and that are rendered on behalf of BlackRock and entities controlling, controlled by, or under common control with BlackRock (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) that provide ongoing services to the Fund (“Affiliated Service Providers”):

Current Fiscal Year End Previous Fiscal Year End
(b) Audit-Related Fees 1 $0 $0
(c) Tax Fees 2 $0 $0
(d) All Other Fees 3 $2,129,000 $2,154,000

1 The nature of the services includes assurance and related services reasonably related to the performance of the audit or review of financial statements not included in Audit Fees, including accounting consultations, agreed-upon procedure reports, attestation reports, comfort letters, out-of-pocket expenses and internal control reviews not required by regulators.

2 The nature of the services includes tax compliance and/or tax preparation, including services relating to the filing or amendment of federal, state or local income tax returns, regulated investment company qualification reviews, taxable income and tax distribution calculations.

3 Non-audit fees of $2,129,000 and $2,154,000 for the current fiscal year and previous fiscal year, respectively, were paid to the Fund’s principal accountant in their entirety by BlackRock, in connection with services provided to the Affiliated Service Providers of the Fund and of certain other funds sponsored and advised by BlackRock or its affiliates for a service organization review and an accounting research tool subscription. These amounts represent aggregate fees paid by BlackRock and were not allocated on a per fund basis.

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

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

3

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

Item 7 – Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies – The board of directors has delegated the voting of proxies for the Fund’s portfolio securities to the Investment Adviser pursuant to the Investment Adviser’s proxy voting guidelines. Under these guidelines, the Investment Adviser will vote proxies related to Fund securities in the best interests of the Fund and its stockholders. From time to time, a vote may present a conflict between the interests of the Fund’s stockholders, on the one hand, and those of the Investment Adviser, or any affiliated person of the Fund or the Investment Adviser, on the other. In such event, provided that the Investment Adviser’s Equity Investment Policy Oversight Committee, or a sub-committee thereof (the “Oversight Committee”) is aware of the real or potential conflict or material non-routine matter and if the Oversight Committee does not reasonably believe it is able to follow its general voting guidelines (or if the particular proxy matter is not addressed in the guidelines) and vote impartially, the Oversight Committee may retain an independent fiduciary to advise the Oversight Committee on how to vote or to cast votes on behalf of the Investment Adviser’s clients. If the Investment Adviser determines not to retain an independent fiduciary, or does not desire to follow the advice of such independent fiduciary, the Oversight Committee shall determine how to vote the proxy after consulting with the Investment Adviser’s Portfolio Management Group and/or the Investment Adviser’s Legal and Compliance Department and concluding that the vote cast is in its client’s best interest notwithstanding the conflict. A copy of the Fund’s Proxy Voting Policy and Procedures are attached as Exhibit 99.PROXYPOL. Information on how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge, (i) at www.blackrock.com and (ii) on the SEC’s website at http://www.sec.gov .

(iv) Portfolio Manager Potential Material Conflicts of Interest

BlackRock has built a professional working environment, firm-wide compliance culture and compliance procedures and systems designed to protect against potential incentives that may favor one account over another. BlackRock has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees and other potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, BlackRock furnishes investment management and advisory services to numerous clients in addition to the Fund, and BlackRock may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to BlackRock, or in which portfolio managers have a personal interest in

6

the receipt of such fees), which may be the same as or different from those made to the Fund. In addition, BlackRock, Inc., its affiliates and significant shareholders and any officer, director, shareholder or employee may or may not have an interest in the securities whose purchase and sale BlackRock recommends to the Fund. BlackRock, Inc., or any of its affiliates or significant shareholders, or any officer, director, shareholder, employee or any member of their families may take different actions than those recommended to the Fund by BlackRock with respect to the same securities. Moreover, BlackRock may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock, Inc.’s (or its affiliates’ or significant shareholders’) officers, directors or employees are directors or officers, or companies as to which BlackRock, Inc. or any of its affiliates or significant shareholders or the officers, directors and employees of any of them has any substantial economic interest or possesses material non-public information. Certain portfolio managers also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for a fund. It should also be noted that Messrs. Reeve and Wheatley-Hubbard may be managing hedge fund and/or long only accounts, or may be part of a team managing hedge fund and/or long only accounts, subject to incentive fees. Messrs. Reeve and Wheatley-Hubbard may therefore be entitled to receive a portion of any incentive fees earned on such accounts.

As a fiduciary, BlackRock owes a duty of loyalty to its clients and must treat each client fairly. When BlackRock purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. BlackRock attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock, Inc. has adopted policies that are intended to ensure reasonable efficiency in client transactions and provide BlackRock with sufficient flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base, as appropriate.

(a)(3) As of December 31, 2017:

Portfolio Manager Compensation Overview

The discussion below describes the portfolio managers’ compensation as of December 31, 2017.

BlackRock’s financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock.

Base Compensation. Generally, portfolio managers receive base compensation based on their position with the firm.

Discretionary Incentive Compensation - Messrs. Reeve and Wheatley-Hubbard

Generally, discretionary incentive compensation for Active Equity portfolio managers is based on a formulaic compensation program. BlackRock’s formulaic portfolio manager compensation program is based on team revenue and pre-tax investment performance relative to appropriate competitors or benchmarks over 1-, 3- and 5-year performance periods, as applicable. In most cases, these benchmarks are the same as the

7

benchmark or benchmarks against which the performance of the Funds or other accounts managed by the portfolio managers are measured. BlackRock’s Chief Investment Officers determine the benchmarks or rankings against which the performance of funds and other accounts managed by each portfolio management team is compared and the period of time over which performance is evaluated. With respect to these portfolio managers, such benchmarks for the Fund and other accounts are:

Portfolio Manager Benchmarks
Stuart Reeve MSCI World Net TR
Index 100% USD Hedged; FTSE World ex UK; MSCI All Country World Index (Net Total Return); MSCI World Gross TR Index in HKD; MSCI World NET TR in GBP Index; MSCI All Country World ex US - Net Return; MSCI World Net TR Index in JPY; 70% MSACWLDNET /

Country World Net TR Index 100% USD Hedged Index in JPY; Morningstar Foreign Large Blend; 70% MSACWLDNET / 30% LIBOR_3MO Index; MSCI AC World Index (NDR); Morningstar World Stock

A smaller element of portfolio manager discretionary compensation may include consideration of: financial results, expense control, profit margins, strategic planning and implementation, quality of client service, market share, corporate reputation, capital allocation, compliance and risk control, leadership, technology and innovation. These factors are considered collectively by BlackRock management and the relevant Chief Investment Officers.

Discretionary Incentive Compensation - Messrs. Accettella and McClements

Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the investment performance, including risk-adjusted returns, of the firm’s assets or strategies under management or supervision by that portfolio manager, and/or the individual’s performance and contribution to the overall performance of these portfolios and BlackRock. Among other things, BlackRock’s Chief Investment Officers make a subjective determination with respect to each portfolio manager’s compensation based on the performance of the Funds, other accounts or strategies managed by each portfolio manager. Performance is generally measured on a pre-tax basis over various time periods including 1-, 3- and 5- year periods, as applicable. The performance of some Funds, other accounts or strategies may not be measured against a specific benchmark.

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash, deferred BlackRock, Inc. stock awards, and/or deferred cash awards that notionally track the return of certain BlackRock investment products.

Typically, the cash portion of the discretionary incentive compensation, when combined with base salary, represents more than 60% of total compensation for the portfolio managers.

8

Portfolio managers generally receive deferred BlackRock, Inc. stock awards as part of their discretionary incentive compensation. Paying a portion of discretionary incentive compensation in the form of deferred BlackRock, Inc. stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock’s ability to sustain and improve its performance over future periods. Deferred BlackRock, Inc. stock awards are generally granted in the form of BlackRock, Inc. restricted stock units that vest ratably over a number of years and, once vested, settle in BlackRock, Inc. common stock. In some cases, additional deferred BlackRock, Inc. stock may be granted to certain key employees as part of a long-term incentive award to aid in retention, align their interests with long-term shareholder interests and motivate performance. Such equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that vest pursuant to the terms of the applicable plan and, once vested, settle in BlackRock, Inc. common stock. The portfolio managers of this Fund have deferred BlackRock, Inc. stock awards.

For some portfolio managers, discretionary incentive compensation is also distributed in the form of deferred cash awards that notionally track the returns of select BlackRock investment products they manage. Providing a portion of discretionary incentive compensation in deferred cash awards that notionally track the BlackRock investment products they manage provides direct alignment with investment product results. Deferred cash awards vest ratably over a number of years and, once vested, settle in the form of cash. Any portfolio manager who is either a managing director or director at BlackRock with compensation above a specified threshold is eligible to participate in the deferred compensation program.

Other Compensation Benefits. In addition to base salary and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (RSP), and the BlackRock Employee Stock Purchase Plan (ESPP). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the Internal Revenue Service limit ($270,000 for 2017). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into a target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the purchase date. Messrs. Accettella and McClements are eligible to participate in these plans.

United Kingdom-based portfolio managers are also eligible to participate in broad-based plans offered generally to BlackRock employees, including broad-based retirement, health and other employee benefit plans. For example, BlackRock has created a variety of incentive savings plans in which BlackRock employees are eligible to participate, including the BlackRock Retirement Savings Plan (RSP) and the BlackRock Employee Stock Purchase Plan (ESPP). The employer contribution to the RSP is between 6% to 15% (dependent on service related entitlement) of eligible pay capped at £150,000 per annum. The RSP offers a range of investment options, including several collective investment funds managed by the firm. BlackRock contributions follow the investment direction set by participants for their own contributions or, in the absence

9

of an investment election being made, are invested into a target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a US dollar value of $25,000 based on its fair market value on the purchase date. Messrs. Reeve and Wheatley-Hubbard are eligible to participate in these plans.
