The Markets in Review

Dear Shareholder,

In the 12 months ended June 30, 2017, risk assets, such as stocks and high-yield bonds, delivered strong performance. These markets showed great resilience during a period with big surprises, including the aftermath of the U.K.’s vote to leave the European Union and the outcome of the U.S. presidential election, which brought only brief spikes in equity market volatility. However, interest rates rose, which worked against high-quality assets with more interest rate sensitivity. Aside from the shortest-term Treasury bills, most U.S. Treasuries posted negative returns, as rising energy prices, modest wage increases and steady job growth led to expectations of higher inflation and anticipation of interest rate increases by the U.S. Federal Reserve (the “Fed”).

The global reflationary theme — rising nominal growth, wages and inflation — was the dominant driver of asset returns during the period, outweighing significant political upheavals and economic uncertainty. Reflationary expectations accelerated after the U.S. election in November 2016 and continued into the beginning of 2017, stoked by expectations that the new administration’s policies would provide an extra boost to U.S. growth.

The Fed has responded to these positive developments by increasing interest rates three times in the last six months, setting expectations for additional interest rate increases and moving toward normalizing monetary policy. For its part, the European Central Bank also began to signal its intent to wind down asset purchases and begin the long move toward policy normalization, contingent upon further improvement in economic growth.

In recent months, growing skepticism about the near-term likelihood of significant U.S. tax reform and infrastructure spending has tempered enthusiasm around the reflation trade. Similarly, renewed concern about oversupply has weighed on energy prices. Nonetheless, financial markets — and to an extent the Fed — have adopted a “wait-and-see” approach to the economic data and potential fiscal stimulus. Although uncertainty has persisted, benign credit conditions, modest inflation and the outlook for economic growth have kept markets relatively tranquil.

In the fifth edition of our Global Investor Pulse Survey, we heard from 28,000 individuals across 18 countries, including more than 4,000 respondents from the United States. While retirement remains the single most important issue for American investors, only a third of respondents feel confident that they will have enough retirement income, and nearly 40% of respondents have yet to begin saving for retirement. We encourage you to talk with your financial advisor and visit blackrock.com for further insight about investing in today’s markets.

| * |  | 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 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 June 30, 2017:

Exchange Symbol |  | Amount Per Common Share |
BGR |  | $ | 0.0776 |
CII |  | $ | 0.0828 |
BDJ |  | $ | 0.0467 |
BOE |  | $ | 0.0780 |
BGY |  | $ | 0.0380 |
BME |  | $ | 0.2000 |
BCX |  | $ | 0.0516 |
BST |  | $ | 0.1000 |
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 each Trust’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.

Performance and Portfolio Management Commentary

Returns for the six months ended June 30, 2017 were as follows:

|  | Returns Based On |
|  | Market Price |  |  | Net Asset Value |
BGR 1,2 |  |  | (6.87 | )% |  |  | (10.55 | )%
Lipper Natural Resources Funds 3 |  |  | (2.89 | )% |  |  | (7.32 | )%

| 1 |  | All returns reflect reinvestment of dividends and/or distributions at actual reinvestment prices.

| 2 |  | The Trust’s discount to NAV narrowed during the period, which accounts for the difference between performance based on price and performance based on NAV.

| 3 |  | Average return. Returns reflect reinvestment of dividends and/or distributions at NAV on the ex-dividend date as calculated by Lipper.

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

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

What factors influenced performance?

• |  | Despite gains for the broader world equity markets, natural resources stocks generally lost ground in the first half of 2017. The downturn largely stemmed from the weakness in energy stocks, which lagged as an unfavorable balance of supply and demand put significant downward pressure on oil prices. In this environment, the Trust produced a negative absolute return at net asset value in the six-month period.

• |  | The investment adviser positioned the portfolio based on its expectation for rising oil prices. Given that oil in fact fell in the first half of the year, this aspect of the Trust’s positioning was a headwind to performance. Specifically, the Trust’s significant exposure to the exploration and production (“E&P”) sub-sector weighed on results.

• |  | The Trust’s position in the pressure pumping and service provider Superior Energy Services, Inc. detracted from absolute performance. The oil services companies Schlumberger Ltd. and Weatherford International Ltd.

|  | announced a joint venture focused on pressure pumping, which could potentially increase competition in this area.

• |  | Anadarko Petroleum Corp., which fell due to the company’s possible link to two operational incidents that involved fatalities, also detracted from absolute performance.

• |  | Tesoro Corp. contributed to absolute performance, as refiners outperformed on the strength of solid demand for petroleum products and weakening oil prices (their major input cost). The company also benefited from its recent acquisition of Western Refining Corp., as the market sees the potential for synergies from the deal.

• |  | A position in Cabot Oil and Gas Corp. made a positive contribution, as well. Natural gas prices held up better than oil, and the market responded positively to increased visibility regarding the expansion of pipelines near the areas in which the company operates. The major North American energy company TransCanada Corp., which rallied following the approval for the Keystone XL pipeline, also added value.

• |  | 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 at a time of weakness in the overall sector.

Describe recent portfolio activity.

• |  | 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. The investment edviser also used the pullback in the broader energy sector to increase the portfolio’s beta somewhat, reflecting its belief that the fundamentals of the oil market could improve in the coming months. The investment adviser focused on companies that can be expected to generate earnings even with oil at $50 per barrel.

|  | BlackRock Energy and Resources Trust

Performance and Portfolio Management Commentary (concluded)

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, below-average costs and higher-quality management teams.

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

What factors influenced performance?

• |  | In sector terms, information technology (“IT”) was the prime contributor to relative performance due to strength among semiconductor and software holdings. Consumer discretionary also aided results, in particular household durables and hotels, restaurants & leisure. Selection in materials and underweight exposure to telecommunication services benefited as well. The main detractor from performance was health care due to weakness in biotechnology and pharmaceuticals. Financials and consumer staples were also a drag, namely capital markets and food & staples retailing.

• |  | On a stock-specific basis, IT holdings Lam Research Corp. and Activision Blizzard Inc. were the top individual contributors. Lam performed very well 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 valuation remained reasonable, reflecting ongoing concerns that this may be the peak of the cycle, resulting in strong stock performance while the fundamentals continued to improve. Activision

|  | outperformed amid consistently strong earnings results, allaying investor worries earlier in the period about weak Call of Duty sales. Investor excitement continued to grow around the company’s new content like Overwatch and Destiny 2, and the secular shifts in the industry such as the movement to digital monetization and eSports.

• |  | Cruise operator Carnival Corp. also added value. Carnival outperformed early in the period after a report from competitor Royal Caribbean confirmed strengthening demand in both the Caribbean and Mediterranean markets. Later, the company delivered strong earnings results, which indicated ongoing favorable supply/demand dynamics in all of the developed cruise markets, leading to continued improvement in pricing power.

• |  | Conversely, underweights to Facebook Inc. and Amazon.com Inc., two of the so-called “FANG” stocks, detracted from relative results as both posted gains of more than 25% during the six months.

• |  | The position in Goldman Sachs Group Inc. also weighed. The stock underperformed after the company reported an uncharacteristically weak quarter reflecting poor performance in its core FICC (fixed income, currencies and commodities) trading business.

• |  | The Trust made use of options, principally written call options on individual stocks, in order to seek enhanced 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.

Describe recent portfolio activity.

• |  | Due to a combination of portfolio trading activity and market movement during the six-month period, the Trust’s exposure to the health care sector considerably increased, particularly within equipment & supplies and pharmaceuticals. Exposure to IT, industrials and materials increased as well. The largest reduction was in consumer staples, largely with respect to beverages and tobacco. Energy exposure also declined.

Performance and Portfolio Management Commentary (concluded)

Describe portfolio positioning at period end.

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?

• |  | The largest contribution to performance for the six-month period came from an overweight to the health care sector. Most notably, an overweight to the health care providers & services industry provided strong relative returns. Within information technology, an overweight to software and stock selection in technology hardware, storage, & peripherals added to relative performance. Lastly, an underweight to telecommunication services (“telecom”) as well as stock selection within the sector contributed to performance, as did stock selection within financials, consumer discretionary and materials.

• |  | The largest detractor from relative return came from stock selection in the consumer staples sector. In particular, selection within the food & staples retailing industry detracted, as non-benchmark holding Kroger Co. sold off on concerns over increasing competition in the wake of the acquisition of Whole Foods by Amazon. Additionally, stock selection in utilities weighed on performance, mainly within the multi-utilities industry. Stock selection in the industrials sector detracted from returns as well, as a significant underweight to the machinery industry proved 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 six-month period, the Trust’s exposure to the industrials, information technology (“IT”), health care, utilities and telecom sectors was increased. Conversely, exposure to consumer staples, consumer discretionary, energy, financials and real estate was decreased.

Describe portfolio positioning at period end.

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

Trust Overview

BlackRock Enhanced Global Dividend Trust’s (BOE) (the “Trust”) primary investment objective is to provide current income and current gains, with a secondary investment objective of long-term capital appreciation. The Trust seeks to achieve its investment objectives by investing primarily in equity securities issued by companies located in countries throughout the world and utilizing an option writing (selling) strategy to seek total return performance and enhance distributions. Under normal circumstances, the Trust invests at least 80% of its net assets in dividend-paying equity securities and at least 40% of its assets outside of the U.S. (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 U.S.). The Trust may invest in securities of companies of any market capitalization, but intends to invest primarily in securities of large capitalization companies.

On March 22, 2017, the Trust’s Board approved a change to the Trust’s name from “BlackRock Global Opportunities Equity Trust” to “BlackRock Enhanced Global Dividend Trust.” The Board also approved changes to certain of the Trust’s non-fundamental investment policies.

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

What factors influenced performance?

• |  | Positive stock selection within the financials sector led contributors for the period, in particular the Trust’s position in Federal Bank Ltd., an Indian retail bank, which benefited from an earnings report that exceeded analysts’ forecasts. Performance was also helped by the Trust’s positioning and security selection within the information technology (“IT”) sector, the top-performing segment during the period. Within IT, holdings in Skyworks Solutions, Inc., a mobile communications semiconductor company that reported favorable earnings, was a notable contributor.

• |  | Conversely, stock selection within the industrials and consumer discretionary sectors detracted from performance. Within industrials, the Trust’s

| position in Acuity Brands, Inc., a manufacturer of energy efficient lighting solutions, led detractors due to a weak earnings report. The company’s management has continued to cite the negative impact of macroeconomic uncertainty on its business, particularly with the recent U.S. election result. Unfavorable stock selection in the consumer discretionary sector was driven by the Trust’s position in Jasper Infotech Private Ltd., a private Indian e-commerce company, which saw its valuation negatively impacted by a more competitive business environment and challenged funding terms.

• |  | Also, during the period, 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 performance.

Describe recent portfolio activity.

• |  | The Trust increased exposure to the consumer staples and health care sectors, funded by reductions to holdings in information technology and consumer discretionary. Regionally, these changes resulted in added exposure to Europe and reduced exposure within the emerging markets, the Pacific Basin and North America.

Describe portfolio positioning at period end.

• |  | The Trust’s largest sector overweights were in the consumer staples, health care and telecommunication services sectors, funded by underweights to financials and IT. Regionally, the Trust was significantly overweight in Europe funded by underweight exposures to Emerging Markets and the Pacific Basin.

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

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?

• |  | Unfavorable stock selection within the internet & direct marketing retail sub-industry of the consumer discretionary sector detracted from performance during the period. This was led by the Trust’s position in Jasper Infotech Private Ltd., a private Indian e-commerce company, which saw its valuation negatively impacted by a more competitive business environment and challenged funding terms. In addition, the Trust’s overweight position in Shire PLC, a global biotechnology company, detracted after the FDA approved a generic equivalent for one of Shire’s popular brand-name therapies.

• |  | For the period, favorable stock selection within the diversified banks sub-industry of the financials sector led relative gains. This was driven by

|  | the Trust’s position in HDFC Bank Ltd., India’s second largest private bank, after HDFC’s shares rallied following a strong earnings report. The next largest contribution came from stock selection in the technology hardware & equipment sub-industry group, most notably holdings of Catcher Technology Co., Ltd., an important supplier of parts for Apple’s iPhone. The stock has performed well year to date on news of strong demand from additional smartphone providers, including Google and Samsung.

• |  | Also, during the period, 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.

Describe recent portfolio activity.

• |  | Over the six-month period, the Trust added to positions in the health care and consumer staples sectors, funded by reductions in the Trust’s financials and consumer discretionary holdings. Regionally, these changes resulted in increased exposure to North America and Europe, and reduced exposure to the emerging markets and the Pacific Basin.

Describe portfolio positioning at period end.

• |  | Relative to the MSCI All Country World Index ex-US, the Trust’s largest sector overweights were in health care and consumer staples, while the largest underweight positions were in financials and consumer discretionary. Regionally, the Trust’s largest overweights were in Europe and North America, while the largest regional underweights were in the Pacific Basin and the emerging markets.

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?

• |  | Underweight positions in the outperforming pharmaceutical stocks Johnson & Johnson and Eli Lilly & Co. detracted from Trust results during the period. Out-of-benchmark positions in the European companies Roche Holding AG and Sanofi SA, which lagged the overall pharmaceutical industry, were additional detractors. In addition, several small- to medium-capitalization holdings in the biotechnology sector hurt performance for the full period despite their strong showing in June.

• |  | On the positive side, the Trust’s positioning in all four health care sub-sectors contributed to relative performance, led by the health care providers & services, biotechnology and pharmaceuticals sub-sectors.

• |  | In healthcare providers & services, the Trust benefited from stock selection in the managed care and healthcare services industries. In the latter group, Amedisys, Inc. and Quest Diagnostics, Inc. reported strong financial results and were leading contributors to performance.

• |  | In biotechnology, the Trust benefited from the outperformance of Vertex Pharmaceuticals, Inc. and AveXis, Inc., both of which reported positive clinical developments. An underweight in Gilead Sciences, Inc., which was hampered by mixed financial results, and the lack of a position in Alexion Pharmaceuticals, Inc., which was pressured by an investigation into its sales practices, also aided performance.

• |  | Jazz Pharmaceuticals PLC — which was boosted by positive clinical results — was a top contributor in the pharmaceuticals industry. A position in AstraZeneca PLC and an underweight in Pfizer, Inc. also aided the Trust’s return in this sub-sector.

• |  | The health care equipment industry was the key source of outperformance in the medical devices area. Several holdings generated positive returns thanks to their solid earnings, including C.R. Bard, Inc. (which was bid for by Becton Dickinson & Co.), Baxter International, Inc., Intuitive Surgical, Inc., Masimo Corp. and Boston Scientific Corp.

• |  | 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 during the six-month period. The Trust also owned private securities during the time period, although this is not a principal strategy.

Describe recent portfolio activity.

• |  | The Trust increased its allocation in the medical devices & supplies sub-sector, while slightly reducing its weightings in the health care providers & services and pharmaceutical sub-sectors.

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.

Trust Summary as of June 30, 2017 |  | BlackRock Resources & Commodities Strategy Trust

Trust Overview

BlackRock Resources & Commodities Strategy Trust’s (BCX) (the “Trust”) primary investment objective is to seek high current income and current gains, with a secondary objective of capital appreciation. The Trust will seek to achieve its investment objectives, under normal market conditions, by investing at least 80% of its total assets in equity securities issued by commodity or natural resources companies, derivatives with exposure to commodity or natural resources companies or investments in securities and derivatives linked to the underlying price movement of commodities or natural resources. While permitted, the Trust does not currently expect to invest in securities and derivatives linked to the underlying price movement of commodities or natural resources. The Trust seeks to pursue this goal primarily by investing in a portfolio of equity securities and utilizing an option overwriting strategy in an effort to seek total return performance and enhance distributions.

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

|  | Returns Based On |
|  | Market Price |  |  | Net Asset Value |

| 3 |  | Average return. Returns reflect reinvestment of dividends and/or distributions at NAV on the ex-dividend date as calculated by Lipper.

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

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

What factors influenced performance?

• |  | Despite gains for the broader world equity markets, natural resources stocks generally lost ground in the first half of 2017. The downturn largely stemmed from the weakness in energy stocks, which lagged as an unfavorable balance of supply and demand put significant downward pressure on oil prices. In this environment, the Trust produced a negative absolute return at net asset value in the six-month period.

• |  | At a time of weak returns for the broader natural resources sector, only certain stocks contributed positively to the Trust’s absolute performance. A position in Packaging Corp of America, which was boosted by an improving demand outlook for U.S. packaging — as demonstrated by increasing utilization rates across the industry — made the largest

|  | contribution at the individual stock level. The Trust’s position in the agriculture science company Monsanto Co. also performed well. Monsanto was bid for in 2016 by the German pharmaceutical company Bayer AG, and its share price subsequently increased toward the bid price as the market grew more confident the deal would receive regulatory approval.

• |  | The Trust’s position in energy stocks was the most significant drag on absolute performance. The oil & gas exploration & production companies Anadarko Petroleum Corp., Cimarex Energy Co. and Devon Energy Corp. were the largest detractors. Anadarko’s stock price was also hurt by the company’s possible link to two operational incidents that involved fatalities.

• |  | 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 at a time of weakness in the overall sector.

Describe recent portfolio activity.

• |  | The investment adviser sought to capitalize on the downturn in the energy sector by modestly increasing the Trust’s exposure to higher-quality exploration & production companies. The Trust also initiated a position in the diversified mining company BHP Billiton Ltd. on the belief that the company can generate cash and de-lever its balance sheet with iron ore prices in their current range.

Describe portfolio positioning at period end.

• |  | The energy sector represented the Trust’s largest allocation, followed by mining and agriculture, respectively.

What factors influenced performance?

• |  | Within software & services, the Trust’s positions in the internet software companies Alibaba Group Holding Ltd. and Tencent Holdings Ltd. led contributors for the period. Both operate as e-commerce companies in China, and benefited from strong earnings reports.

• |  | Conversely, the Trust’s position in Jasper Infotech Private Ltd., a private Indian e-commerce company, led detractors for the period, as the company’s valuation was negatively impacted by a more competitive business environment and challenged funding terms. Within the internet & direct marketing retail sub-industry, shares of NetShoes, a

| Brazilian online retailer of sporting goods, also meaningfully detracted following the company’s initial public stock offering amid heightened political turmoil in the region.

• |  | During the period, 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 the technology hardware & equipment sub-sector, and reduced its holdings in the real estate and consumer durables & apparel sub-sectors. Regionally, the Trust added to positions in the emerging markets, funded by reductions within Europe, the Pacific Basin and North America.

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 Trust 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 Overview

BlackRock Utility and Infrastructure 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 and Infrastructure 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 and 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. 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.

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

|  | Returns Based On |
|  | Market Price |  |  | Net Asset Value |
BUI 1,2 |  |  | 15.67% |  |  |  | 10.51% |

| 3 |  | Average return. Returns reflect reinvestment of dividends and/or distributions at NAV on the ex-dividend date as calculated by Lipper.

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

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

What factors influenced performance?

• |  | The largest contributor to absolute return was the Trust’s stock selection in 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 benefitted from its lack of exposure to Southern Co., as well as from overweight positions in NextEra Energy, Inc. and Italian utility operator Enel SpA.

• |  | The largest detractor from absolute returns was the Trust’s overweight position in the energy sector, which has been negatively impacted by

|  | weak crude oil prices. The Trust’s stock selection in the oil, gas, & consumable fuels industry detracted from performance, especially among midstream master limited partnerships Plains All American Pipeline, L.P., Energy Transfer Partners, L.P., and Dominion Energy Midstream Partners, LP. Also detracting from the Trust’s return was an underweight position in the industrials sector, particularly among transportation infrastructure industry stocks including airport services providers Aena, S.A. in Spain and Grupo Aeroportuario del Sureste, S.A.B. de C.V. in Mexico.

• |  | Also, during the period, 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 made few changes to its sector and industry allocations. In terms of individual positions, notable changes included adding to existing positions in Enel SpA and FirstEnergy Corp., while exiting the Trust’s position in Spanish renewable electricity company EDP Renovaveis S.A. and trimming exposure to multi-utility provider CMS Energy Corp.

Describe portfolio positioning at period end.

• |  | The utilities sector accounted for approximately 63% of the Trust’s assets, with holdings concentrated in U.S. electric and multi-utilities. Against a backdrop of historically low interest rates, the demand for equity yield has led to valuations for U.S. utilities that are high relative to their historical

|  | BlackRock Utility and Infrastructure Trust

Performance and Portfolio Management Commentary (concluded)

| levels, placing even greater importance on stock selection. As such, the Trust was focused on owning companies with strong management teams that offer the potential for above-sector growth in earnings and dividends.

|  | The Trust had a preference for regulated utilities over their non-regulated counterparts given their existing barriers to entry, strong balance sheets, and lower sensitivity to commodity prices.

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 asset 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 |  | Herein Referred to As |  | Organized |  | Diversification Classification
BlackRock Energy and Resources Trust |  | BGR |  | 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 Utility and Infrastructure Trust |  | BUI |  | Delaware |  | Diversified*

| * |  | The Trust’s classification changed from non-diversified to diversified during the reporting period.

The Boards 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 the 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 six months ended June 30, 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.

2. Significant Accounting Policies:

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

Investment Transactions and Income Recognition: For financial reporting purposes, investment transactions are recorded on the dates the transactions are entered into (the “trade dates”). Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is 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, is 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 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

|  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  | 111

Notes to Financial Statements (continued) |  |

to be excluded from treatment as a “senior security.” Furthermore, if required by an exchange or counterparty agreement, the Trusts may be required to deliver/deposit cash and/or securities to/with an exchange, or broker-dealer or custodian as collateral for certain investments or obligations.

Distributions: Distributions 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.

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 officer’s and trustees’ 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.

SEC Reporting Modernization: The U.S. Securities and Exchange Commission (“SEC”) adopted new rules and forms and amended other rules to enhance the reporting and disclosure of information by registered investment companies. As part of these changes, the SEC amended Regulation S-X to standardize and enhance disclosures in investment company financial statements. The compliance date for implementing the new or amended rules is August 1, 2017.

Indemnifications: In the normal course of business, a Trust enters into contracts that contain a variety of representations that provide general indemnification. A Trust’ 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.

3. Investment Valuation and fair Value Measurements:

Investment Valuation Policies: The Trusts’ investments are valued at fair value (also referred to as “market value” within the financial statements) as of the close of trading on the New York Stock Exchange (“NYSE”) (generally 4:00 p.m., Eastern time). U.S. GAAP defines fair value as the price the Trusts would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Trusts determine

112 |  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  |

Notes to Financial Statements (continued) |  |

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’ assets and liabilities:

• |  | 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 often 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.

• |  | 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.

• |  | 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 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 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

|  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  | 113

Notes to Financial Statements (continued) |  |

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 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.

Notes to Financial Statements (continued) |  |

As of June 30, 2017, certain investments of BCX and BST were valued using NAV per share as no quoted market value is available and therefore have been excluded from the fair value hierarchy.

4. 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 does 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 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:

1 Cash collateral with a value of $1,167,311 and $1,060,821 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. 2 The market value of the loaned securities is determined as of June 30, 2017. Additional collateral is delivered to the Fund on the next business day in accordance with the MSLA. The net amount would be subject to the borrower default indemnity in the event of default by the counterparty. |

|  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  | 115

Notes to Financial Statements (continued) |  |

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.

5. Derivative Financial Instruments:

The Trusts engage in various portfolio investment strategies using derivative contracts both to increase the returns of the Trusts and/or to manage their exposure to certain risks such as equity risk or commodity price 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 value of the contract at the time it was opened and the value 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 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.

116 |  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  |

Notes to Financial Statements (continued) |  |

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. In addition, certain ISDA Master Agreements allow counterparties to terminate derivative contracts prior to maturity in the event each Trust’s net assets decline by a stated percentage or the Trusts fail to meet the terms of their ISDA Master Agreements. The result would cause the Trusts to accelerate payment of any net liability owed to the counterparty.

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.

6. 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% |

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).

|  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  | 117

Notes to Financial Statements (continued) |  |

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.

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 period ended June 30, 2017 amounted to $22,614.

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:

|  |  |  |  | Expiration Date
BST |  |  | 0.20% |  |  | December 31, 2018
|  |  | 0.15% |  |  | December 31, 2019
|  |  | 0.10% |  |  | December 31, 2020
|  |  | 0.05% |  |  | December 31, 2021

The Manager voluntarily agreed to waive a portion of the investment advisory fees on the following Trusts as a percentage of its 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 six months ended June 30, 2017, the investment advisory fees waived which are included in fees waived by the Manager in the Statements of Operations were as follows:

BGR |  | $ | 225,624 |
BOE |  | $ | 242,146 |
BGY |  | $ | 357,471 |
BST |  | $ | 504,850 |

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.

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 by the Manager in the Statements of Operations. For the six months ended June 30, 2017, the amounts waived were as follows:

BGR |  | $ | 2,069 |
CII |  | $ | 7,184 |
BDJ |  | $ | 2,683 |
BOE |  | $ | 10,666 |
BGY |  | $ | 10,525 |
BME |  | $ | 2,842 |
BCX |  | $ | 4,507 |
BST |  | $ | 553 |
BUI |  | $ | 1,422 |

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 by the Manager in the Statements of Operations. For the six months ended June 30, 2017, BOE waived $9,522 in investment advisory fees pursuant to these arrangements.

Notes to Financial Statements (continued) |  |

Securities Lending: The U.S. Securities and Exchange Commission 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% on the value redeemed or temporarily restrict redemptions 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 six months ended June 30, 2017, each Trust paid BIM the following amounts for securities lending agent services:

BGR |  | $ | 5,781 |
CII |  | $ | 287 |
BDJ |  | $ | 376 |
BOE |  | $ | 8,140 |
BGY |  | $ | 125 |
BME |  | $ | 325 |
BCX |  | $ | 23,737 |
BST |  | $ | 9,067 |
BUI |  | $ | 969 |

Officers and Trustees: Certain officers and/or Trustees of the Trusts are officers and/or trustees 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 Officer and Trustees in the Statements of Operations.

Other Transactions: During the six months ended June 30, 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.

The Trusts may purchase securities from, or sell securities to, an affiliated fund provided the affiliation is due solely to having a common investment adviser, common officers, or common trustees. For the six months ended June 30, 2017, the purchase and sale transactions and any net realized gains (losses) with an affiliated fund in compliance with Rule 17a-7 under the 1940 Act were as follows:

|  | Purchase |  |  | Sales |  |  | Net Realized Gain (Loss) |
CII |  | $ | 343,935 |  |  |  | — |  |  |  | — |
BOE |  | $ | 4,785,895 |  |  |  | — |  |  |  | — |
BGY |  | $ | 4,300,195 |  |  | $ | 2,931,108 |  |  | $ | (257,002 | )
BUI |  | $ | 5,775,415 |  |  |  | — |  |  |  | — |

7. Purchases and Sales:

8. Income Tax Information:

It is each Trust’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute substantially all of their taxable income to their 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 two years ended December 31, 2016, the period ended December 31, 2014 and each of the two years 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 two years ended December 31, 2016 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 June 30, 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.

As of December 31, 2016, the Trusts had capital loss carryforwards available to offset future realized capital gains through the indicated expiration dates as follows:

9. Principal Risks:

In the normal course of business, the Trusts invest in securities and enter into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer to meet all its obligations, including the ability to pay principal and interest when due (issuer credit risk). The value of securities held by the Trusts may decline in response to certain events, including those directly involving the issuers of securities owned by the Trusts. Changes arising from the general economy, the overall market and local, regional or global political and/or social instability, as well as currency, interest rate and price fluctuations, may also affect the securities’ value.

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’s 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’s 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’s ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers.

Notes to Financial Statements (continued) |  |

Counterparty Credit Risk: Similar to issuer 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

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 and BGY invest a substantial amount of their assets in issuers located in a single country or a limited number of countries. When the Trusts concentrate their investments in this manner, it assumes the risk that economic, political and social conditions in those countries may have a significant impact on their 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.

10. 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.

On June 9, 2016, BME filed a final prospectus with the U.S. Securities and Exchange Commission (“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 net asset value (“NAV”) per Common Share (calculated within 48 hours of pricing). As of period end, 1,804,130 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.

On October 26, 2016, the Board approved the Trusts’ participation in an open market share repurchase program (the “Share Repurchase Program”). Each Trust is eligible to purchase, at prevailing market prices, up to 5% of its common shares outstanding as of the close of business on October 28, 2016, subject to certain conditions. Repurchases may be made through November 30, 2017. There is no assurance that a Trust will purchase shares in any particular amounts. The shares repurchased during the six months ended June 30, 2017 are as follows:

|  | Shares Repurchased |  |  | Amount1 |

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements |  |

The Board of Directors or Trustees, as applicable (each, a “Board,” collectively, the “Boards,” and the members of which are referred to as “Board Members”), of BlackRock Energy and Resources Trust (“BGR”), BlackRock Enhanced Capital and Income Fund, Inc. (“CII”), BlackRock Enhanced Equity Dividend Trust (“BDJ”), BlackRock Global Opportunities Equity Trust (“BOE”), BlackRock Health Sciences Trust (“BME”), BlackRock International Growth and Income Trust (“BGY”), BlackRock Resources & Commodities Strategy Trust (“BCX”), BlackRock Utility and Infrastructure Trust (“BUI”) and BlackRock Science and Technology Trust (“BST” and together with BGR, CII, BDJ, BOE, BME, BGY, BCX and BUI, each a “Trust,” and, collectively, the “Trusts”) met in person on April 27, 2017 (the “April Meeting”) and June 7-8, 2017 (the “June Meeting”) to consider the approval of each Trust’s investment advisory agreement (the “Advisory Agreement”) with BlackRock Advisors, LLC (the “Manager”), each Trust’s investment advisor. The Board of each of BGR and BCX also considered the approval of the sub-advisory agreement (the “Sub-Advisory Agreement”) among the Manager, BlackRock International Limited (the “Sub-Advisor”), and the Trust.

The Manager and the Sub-Advisor are referred to herein as “BlackRock”. The Advisory Agreements and the Sub-Advisory Agreements are referred to herein as the “Agreements.”

Activities and Composition of the Board

On the date of the June Meeting, the Board of each Trust consisted of eleven individuals, nine of whom were not “interested persons” of the Trust as defined in the Investment Company Act of 1940, as amended (the “1940 Act”) (the “Independent Board Members”). The Board Members are responsible for the oversight of the operations of its Trust and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Board Members have retained independent legal counsel to assist them in connection with their duties. The Chair of each Board is an Independent Board Member. Each Board has established five standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee, and an Executive Committee, each of which is chaired by an Independent Board Member and composed of Independent Board Members (except for the Executive Committee, which also has one interested Board Member).

The Agreements

Pursuant to the 1940 Act, each Board is required to consider the continuation of the Advisory Agreement for its Trust, and with respect to BGR and BCX, the Sub-Advisory Agreement, on an annual basis.

Each Board has four quarterly meetings per year, each extending over two days, a fifth one-day meeting to consider specific information surrounding the consideration of renewing the Agreement(s) for its Trust and additional in-person and telephonic meetings as needed. In connection with this year-long deliberative process, each Board assessed, among other things, the nature, extent and quality of the services provided to its Trust by BlackRock, BlackRock’s personnel and affiliates, including, as applicable; investment management, administrative, and shareholder services; the oversight of fund service providers; marketing; risk oversight; compliance; and ability to meet applicable legal and regulatory requirements.

Each Board, acting directly and through its committees, considers at each of its meetings, and from time to time as appropriate, factors that are relevant to its annual consideration of the renewal of the Agreement(s) for its Trust, including the services and support provided by BlackRock to the Trust and its shareholders. BlackRock also furnished additional information to each Board in response to specific questions from the Board. This additional information is discussed further below in the section titled “Board Considerations in Approving the Agreements.” Among the matters each Board considered were: (a) investment performance for one-year, three-year, five-year, ten-year, and/or since inception periods, as applicable, against peer funds, applicable benchmarks, and performance metrics, as applicable, as well as senior management’s and portfolio managers’ analysis of the reasons for any over-performance or underperformance relative to its peers, benchmarks, and other performance metrics, as applicable; (b) fees, including advisory, administration, if applicable, paid to BlackRock and its affiliates by the Trust for services; (c) Trust operating expenses and how BlackRock allocates expenses to the Trust; (d) the resources devoted to, risk oversight of, and compliance reports relating to, implementation of the Trust’s investment objective(s), policies and restrictions, and meeting regulatory requirements; (e) the Trust’s adherence to its compliance policies and procedures; (f) the nature, cost and character of non-investment management services provided by BlackRock and its affiliates; (g) BlackRock’s and other service providers’ internal controls and risk and compliance oversight mechanisms; (h) BlackRock’s implementation of the proxy voting policies approved by the Board; (i) the use of brokerage commissions and execution quality of portfolio transactions; (j) BlackRock’s implementation of the Trust’s valuation and liquidity procedures; (k) an analysis of management fees for products with similar investment mandates across the open-end fund, closed-end fund, sub-advised mutual fund, collective investment trust, and institutional separate account product channels, as applicable, and the similarities and differences between these products and the services provided as compared to the Trust; (l) BlackRock’s compensation methodology for its investment professionals and the incentives and accountability it creates, along with investment professionals’ investments in the fund(s) they manage; and (m) periodic updates on BlackRock’s business.

Board Considerations in Approving the Agreements

The Approval Process: Prior to the April Meeting, each Board requested and received materials specifically relating to the Agreement(s) for its Trust. Each Board is continuously engaged in a process with its independent legal counsel and BlackRock to review the nature and scope of the information provided to better assist its deliberations.

The materials provided to the Board of each Trust in connection with the April Meeting included (a) information independently compiled and prepared by Broadridge Financial Solutions, Inc. (“Broadridge”) on Trust fees and expenses as compared with a peer group of funds as determined by Broadridge

|  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  | 123

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

(“Expense Peers”) and the investment performance of the Trust as compared with a peer group of funds as determined by Broadridge,1 as well as the performance of the Trust as compared with its custom benchmark; (b) information on the profits realized by BlackRock and its affiliates pursuant to the Trust’s Agreement(s) and a discussion of fall-out benefits to BlackRock and its affiliates; (c) a general analysis provided by BlackRock concerning investment management fees charged to other clients, such as institutional clients, sub-advised mutual funds, and open-end funds, under similar investment mandates, as applicable; (d) review of non-management fees; (e) the existence, impact and sharing of potential economies of scale; and (f) a summary of aggregate amounts paid by the Trust to BlackRock.

At the April Meeting, each Board reviewed materials relating to its consideration of the Agreement(s) for its Trust. As a result of the discussions that occurred during the April Meeting, and as a culmination of each Board’s year-long deliberative process, each Board presented BlackRock with questions and requests for additional information. BlackRock responded to these requests with additional written information in advance of the June Meeting. Topics covered included: (a) fund repositionings and portfolio management changes, including additional information about the portfolio managers, research teams, organization and methods and historical track records of the teams, and the potential impact of such changes on fund performance and the costs of such changes; (b) scientific active equity management; (c) BlackRock’s option overwrite policy; (d) differences in services between closed-end funds and mutual funds; (d) market discount; and (e) adviser profitability.

At the June Meeting, each Board, including the Independent Board Members, unanimously approved the continuation of the Advisory Agreement between the Manager and its Trust for a one year term ending June 30, 2018. The Board of each of BGR and BCX, including the Independent Board Members, also unanimously approved the continuation of the Sub-Advisory Agreement between the Manager and the Sub-Advisor, with respect to its Trust, for a one-year term ending June 30, 2018. In approving the continuation of the Agreement(s) for its Trust, each Board considered: (a) the nature, extent and quality of the services provided by BlackRock; (b) the investment performance of the Trust; (c) the advisory fee and the cost of the services and profits to be realized by BlackRock and its affiliates from their relationship with the Trust; (d) the Trust’s costs to investors compared to the costs of Expense Peers and performance compared to the relevant performance metrics as previously discussed; (e) the sharing of potential economies of scale; (f) fall-out benefits to BlackRock and its affiliates as a result of its relationship with the Trust; and (g) other factors deemed relevant by the Board Members.

Each Board also considered other matters it deemed important to the approval process, such as other payments made to BlackRock or its affiliates relating to securities lending and cash management, services related to the valuation and pricing of Trust portfolio holdings, and advice from independent legal counsel with respect to the review process and materials submitted for the Board’s review. Each Board noted the willingness of BlackRock personnel to engage in open, candid discussions with the Board. Each Board did not identify any particular information as determinative, and each Board Member may have attributed different weights to the various items considered.

A. Nature, Extent and Quality of the Services Provided by BlackRock: Each Board, including the Independent Board Members, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services and the resulting performance of its Trust. Throughout the year, each Board compared its Trust’s performance to the performance of a comparable group of closed-end funds, relevant benchmark, and performance metrics, as applicable. Each Board met with BlackRock’s senior management personnel responsible for investment activities, including the senior investment officers. Each Board also reviewed the materials provided by its Trust’s portfolio management team discussing the Trust’s performance and the Trust’s investment objective(s), strategies and outlook.

Each Board considered, among other factors, with respect to BlackRock: the number, education and experience of investment personnel generally and its Trust’s portfolio management team; BlackRock’s research capabilities; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use of technology; commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managers and other research, advisory and management personnel. Each Board engaged in a review of BlackRock’s compensation structure with respect to the Trust’s portfolio management team and BlackRock’s ability to attract and retain high-quality talent and create performance incentives.

In addition to investment advisory services, each Board considered the quality of the administrative and other non-investment advisory services provided to its Trust. BlackRock and its affiliates provide each Trust with certain administrative, shareholder, and other services (in addition to any such services provided to the Trust by third parties) and officers and other personnel as are necessary for the operations of the Trust. In particular, BlackRock and its affiliates provide each Trust with administrative services including, among others: (i) preparing disclosure documents, such as the prospectus and the statement of additional information in connection with the initial public offering, and, with respect to BME, registration statements in connection with BME’s equity shelf program, and periodic shareholder reports; (ii) preparing communications with analysts to support secondary market trading of the Trust; (iii) oversight of daily accounting and pricing; (iv) preparing periodic filings with regulators and stock exchanges; (v) overseeing and coordinating the activities of other service providers; (vi) organizing Board meetings and preparing the materials for such Board meetings; (vii) providing legal and compliance support; (viii) furnishing analytical and other support to assist the Board in its consideration of strategic issues such as the merger, consolidation or repurposing of certain closed-end funds; and (ix) performing other administrative functions necessary for the operation of the Trust, such as tax reporting, fulfilling regulatory filing requirements and call center services. Each Board reviewed the structure and duties of BlackRock’s fund administration, share-

holder services, and legal & compliance departments and considered BlackRock’s policies and procedures for assuring compliance with applicable laws and regulations.

B. The Investment Performance of the Trusts and BlackRock: Each Board, including the Independent Board Members, also reviewed and considered the performance history of its Trust. In preparation for the April Meeting, the Board of each Trust was provided with reports independently prepared by Broadridge, which included a comprehensive analysis of the Trust’s performance. Each Board also reviewed a narrative and statistical analysis of the Broadridge data that was prepared by BlackRock. In connection with its review, the Board of each Trust received and reviewed information regarding the investment performance, based on net asset value (NAV), of the Trust as compared to other funds in its applicable Broadridge category and the performance of the Trust as compared with its custom benchmark. Each Board was provided with a description of the methodology used by Broadridge to select peer funds and periodically meets with Broadridge representatives to review its methodology. Each Board was provided with information on the composition of the Broadridge performance universes and expense universes. Each Board and its Performance Oversight Committee regularly review, and meet with Trust management to discuss, the performance of its Trust throughout the year.

In evaluating performance, each Board recognized that the performance data reflects a snapshot of a period as of a particular date and that selecting a different performance period could produce significantly different results. Further, each Board recognized that it is possible that long-term performance can be adversely affected by even one period of significant underperformance so that a single investment decision or theme has the ability to affect long-term performance disproportionately.

The Board of BGR noted that for each of the one-, three- and five-year periods reported, the Trust underperformed its customized benchmark. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for BGR. The Board and BlackRock reviewed BGR’s underperformance during these periods. The Board was informed that, among other things, BGR’s underweight position in the refining and marketing sub-sector and the portfolio management team’s decision to increase BGR’s oil price sensitivity detracted from performance over the three- and five-year periods.

In further discussions with the Board of BGR, BlackRock noted that BGR had a voluntary advisory fee waiver in place. After discussions between the Board, including Independent Board Members, and BlackRock, the Board of BGR and BlackRock agreed to increase the voluntary advisory fee waiver. The waiver increase was implemented on July 1, 2017. This waiver may be discontinued at any time without notice.

The Board of CII noted that for each of the one-, three- and five-year periods reported, CII underperformed its customized benchmark. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for CII. The Board and BlackRock reviewed CII’s underperformance during these periods. The Board was informed that, among other things, poor stock selection in the consumer discretionary sector, an overweight position in banks and an underweight position in stability/bond proxies were the primary detractors from performance over the one-year period.

In further discussions with the Board of CII, BlackRock noted that as of April 30, 2017, CII’s performance has shown improvement for the one-year period relative to CII’s customized benchmark. It was also noted that the Board and BlackRock concurred in making changes within the portfolio management team. These portfolio management changes were implemented on March 29, 2017.

The Board of BDJ noted that for each of the one-, three- and five-year periods reported, BDJ underperformed its customized benchmark. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for the Trust. The Board and BlackRock reviewed BDJ’s underperformance during these periods. The Board of BDJ was informed that, among other things, poor stock selection in the industrials and consumer staples sectors was the primary detractor from relative performance over the one-year period. The largest detractor from relative performance over the five-year period stemmed from poor stock selection and underweight positions in the IT sector.

In further discussions with the Board of BDJ, BlackRock noted that as of April 30, 2017, BDJ’s performance has shown improvement for the one- and three-year periods relative to BDJ’s customized benchmark.

The Board of BOE noted that for each of the one-, three- and five-year periods reported, the Trust underperformed its customized benchmark. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for BOE. The Board and BlackRock reviewed BOE’s underperformance during these periods. The Board of BOE was informed that, among other things, BOE’s underperformance was primarily driven by factor biases over the one-, three- and five-year periods, particularly being overweight volatility and underweight profitability and yield.

In further discussions with the Board of BOE, BlackRock noted that effective June 12, 2017, BOE had undergone certain changes to its investment process and portfolio management team, and in connection with such changes, BOE changed its name from Global Opportunities Equity Trust to Enhanced Global Dividend Trust. It was noted that BlackRock believes these changes will benefit investors and that BlackRock has agreed to pay half of the transition costs associated with BOE’s repositioning. Additionally, it was noted that the Trust had a voluntary advisory fee waiver in place. After discussions between the Board, including Independent Board Members, and BlackRock, the Board and BlackRock agreed to increase the voluntary advisory fee waiver. This waiver increase was implemented on July 1, 2017. This waiver may be discontinued at any time without notice.

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

The Board of BME noted that for the one-, three- and five-year periods reported, BME underperformed, exceeded and exceeded its customized benchmark. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for BME. The Board and BlackRock reviewed BME’s underperformance during the one-year period. The Board of BME was informed that, among other things, the primary detractor from performance was an underweight position in the pharmaceutical sub-sector.

The Board of BGY noted that for each of the one-, three- and five-year periods reported, the Trust underperformed its customized benchmark. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for the Trust. The Board and BlackRock reviewed BGY’s underperformance during these periods. The Board was informed that, among other things, BGY’s underperformance was primarily driven by factor biases over the one-, three- and five-year periods, particularly being overweight volatility and underweight profitability and yield.

In further discussions with the Board of BGY, BlackRock noted that effective June 12, 2017, BGY had undergone certain changes to its investment process and portfolio management team, and in connection with such changes, BGY changed its name from International Growth and Income Trust to Enhanced International Dividend Trust. It was noted that BlackRock believes that these changes will benefit investors and that BlackRock has agreed to pay half of the transition costs associated with BGY’s repositioning. Additionally, it was noted that BGY has a voluntary advisory fee waiver in place. This waiver may be discontinued at any time without notice.

The Board of BCX noted that for the one-year, three-year and since-inception periods reported, BCX underperformed, exceeded and underperformed, respectively, its customized benchmark. The since-inception period is as of the customized benchmark creation date. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for BCX. The Board of BCX and BlackRock reviewed BCX’s underperformance during the one-year and since-inception periods.

The Board of BST noted that for the one-year and since-inception periods reported, BST underperformed and exceeded, respectively, its customized benchmark. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for BST. The Board of BST and BlackRock reviewed BST’s underperformance during the one-year period. The Board was informed that, among other things, BST’s overweight exposures to growth and volatility and underweight exposures to yield and profitability were the primary detractors from performance.

The Board of BUI noted that for each of the one-, three- and five-year periods reported, BUI underperformed its customized benchmark. BlackRock believes that performance relative to the customized benchmark is an appropriate performance metric for BUI. The Board and BlackRock reviewed BUI’s underperformance during these periods. The Board of BUI was informed that, among other things, the primary detractor from relative performance over the one-year period was stock selection in the oil, gas & consumable fuels industry. Stock selection in the construction & engineering industry also detracted from relative performance over the one-year period.

In further discussions with the Board of BUI, BlackRock noted that as of March 31, 2017, BUI’s performance has shown improvement for the five-year period relative to BUI’s customized benchmark. It was also noted that the Board and BlackRock concurred in making changes within the portfolio management team. These portfolio management changes were implemented on March 15, 2017. After discussions between the Board, including Independent Board Members, and BlackRock, the Board and BlackRock agreed to a voluntary advisory fee waiver. This waiver was implemented on July 1, 2017. This waiver may be discontinued at any time without notice.

C. Consideration of the Advisory/Management Fees and the Cost of the Services and Profits to be Realized by BlackRock and its Affiliates from their Relationship with the Trusts: Each Board, including the Independent Board Members, reviewed its Trust’s contractual management fee rate compared with the other funds in its Broadridge category. The contractual management fee rate represents a combination of the advisory fee and any administrative fees, before taking into account any reimbursements or fee waivers. Each Board also compared its Trust’s total expense ratio, as well as its actual management fee rate as a percentage of total assets, to those of other funds in its Broadridge category. The total expense ratio represents a fund’s total net operating expenses, excluding any investment related expenses. The total expense ratio gives effect to any expense reimbursements or fee waivers that benefit a fund, and the actual management fee rate gives effect to any management fee reimbursements or waivers that benefit a fund. Each Board considered the services provided and the fees charged by BlackRock and its affiliates to other types of clients with similar investment mandates, as applicable, including institutional accounts and sub-advised mutual funds (including mutual funds sponsored by third parties).

Each Board received and reviewed statements relating to BlackRock’s financial condition. Each Board reviewed BlackRock’s profitability methodology and was also provided with a profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to its Trust. Each Board reviewed BlackRock’s profitability with respect to its Trust and other funds the Board currently oversees for the year ended December 31, 2016 compared to available aggregate profitability data provided for the prior two years. Each Board reviewed BlackRock’s profitability with respect to certain other U.S. fund complexes managed by the Manager and/or its affiliates. Each Board reviewed BlackRock’s assumptions and methodology of allocating expenses in the profitability analysis, noting the inherent limitations in allocating costs among various advisory products. Each Board recognized that profitability may be affected by numerous factors including, among other things, fee waivers and expense reimbursements by the Manager, the types of funds managed, precision of expense allocations and business mix. As a result, calculating and comparing profitability at individual fund levels is difficult.

Each Board noted that, in general, individual fund or product line profitability of other advisors is not publicly available. Each Board reviewed BlackRock’s overall operating margin, in general, compared to that of certain other publicly-traded asset management firms. Each Board considered the differences

126 |  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  |

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

between BlackRock and these other firms, including the contribution of technology at BlackRock, BlackRock’s expense management, and the relative product mix.

In addition, each Board considered the cost of the services provided to its Trust by BlackRock, and BlackRock’s and its affiliates’ profits relating to the management of its Trust and the other funds advised by BlackRock and its affiliates. As part of its analysis, each Board reviewed BlackRock’s methodology in allocating its costs of managing its Trust, to the Trust. Each Board may receive and review information from independent third parties as part of its annual evaluation. Each Board considered whether BlackRock has the financial resources necessary to attract and retain high quality investment management personnel to perform its obligations under the Trust’s Agreement(s) and to continue to provide the high quality of services that is expected by the Board. Each Board further considered factors including but not limited to BlackRock’s commitment of time, assumption of risk, and liability profile in servicing its Trust in contrast to what is required of BlackRock with respect to other products with similar investment mandates across the open-end fund, closed-end fund, sub-advised mutual fund, collective investment trust, and institutional separate account product channels, as applicable.

The Board of BGR noted that BGR’s contractual management fee rate ranked in the third quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile, relative to the Expense Peers. In addition, the Board noted that BlackRock had voluntarily agreed to waive a portion of the advisory fee payable by BGR. After discussion between the Board, including the Independent Board Members, and BlackRock, the Board and BlackRock agreed to increase the voluntary advisory fee waiver. This waiver increase was implemented on July 1, 2017. This waiver may be discontinued at any time without notice.

The Board of each of CII, BDJ and BCX noted that its Trust’s contractual management fee rate ranked in the first quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile, relative to its Expense Peers.

The Board of BOE noted that BOE’s contractual management fee rate ranked in the second quartile, and that the actual management fee rate and total expense ratio each ranked in the second quartile, relative to the Expense Peers. In addition, the Board noted that BlackRock had voluntarily agreed to waive a portion of the advisory fee payable by BOE. After discussion between the Board, including the Independent Board Members, and BlackRock, the Board and BlackRock agreed to increase the voluntary advisory fee waiver. The waiver increase was implemented on July 1, 2017. This waiver may be discontinued at any time without notice.

The Board of BME noted that BME’s contractual management fee rate ranked first out of three funds, and that the actual management fee rate and total expense ratio ranked second out of four funds, and in the first quartile, respectively, relative to the Expense Peers.

The Board of BGY noted that BGY’s contractual management fee rate ranked in the first quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile, relative to the Expense Peers. The Board also noted that BlackRock had voluntarily agreed to waive a portion of the advisory fee payable by BGY. This waiver was implemented on July 1, 2015. After discussions between the Board, including Independent Board Members, and BlackRock, the Board and BlackRock agreed to a continuation of the voluntary advisory fee waiver. This waiver may be discontinued at any time without notice.

The Board of BST noted that BST’s contractual management fee rate ranked first out of three funds, and that the actual management fee rate and total expense ratio ranked first out of four funds and in the first quartile, respectively, relative to the Expense Peers. The Board also noted that BlackRock has contractually agreed to waive a portion of the advisory fee payable by BST through December 31, 2021.

The Board of BUI noted that BUI’s contractual management fee rate ranked in the first quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile, relative to the Expense Peers. After discussion between the Board, including the Independent Board Members, and BlackRock, the Board and BlackRock agreed to a voluntary advisory fee waiver. This waiver was implemented on July 1, 2017. This waiver may be discontinued at any time without notice.

D. Economies of Scale: Each Board, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of its Trust increase. Each Board also considered the extent to which its Trust benefits from such economies in a variety of ways, and whether there should be changes in the advisory fee rate or breakpoint structure in order to enable the Trust to more fully participate in these economies of scale. Each Board considered its Trust’s asset levels and whether the current fee was appropriate.

Based on each Board’s review and consideration of the issue, each Board concluded that most closed-end funds do not have fund level breakpoints because closed-end funds generally do not experience substantial growth after the initial public offering. They are typically priced at scale at a fund’s inception. The Board of BME noted that although BME may from time-to-time make additional share offerings pursuant to its equity shelf program, the growth of BME’s assets will occur primarily through the appreciation of its investment portfolio.

E. Other Factors Deemed Relevant by the Board Members: Each Board, including the Independent Board Members, also took into account other ancillary or “fall-out” benefits that BlackRock or its affiliates may derive from their respective relationships with its Trust, both tangible and intangible, such as BlackRock’s ability to leverage its investment professionals who manage other portfolios and risk management personnel, an increase in BlackRock’s profile in the investment advisory community, and the engagement of BlackRock’s affiliates as service providers to the Trust, including for administrative,

|  | SEMI-ANNUAL REPORT |  | JUNE 30, 2017 |  | 127

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

securities lending and cash management services. Each Board also considered BlackRock’s overall operations and its efforts to expand the scale of, and improve the quality of, its operations. Each Board also noted that BlackRock may use and benefit from third party research obtained by soft dollars generated by certain registered fund transactions to assist in managing all or a number of its other client accounts.

In connection with its consideration of the Agreement(s) for its Trust, each Board also received information regarding BlackRock’s brokerage and soft dollar practices. Each Board received reports from BlackRock which included information on brokerage commissions and trade execution practices throughout the year.

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

Each Board also considered the various notable initiatives and projects BlackRock performed in connection with its closed-end fund product line. These initiatives included the redemption of AMPS; developing equity shelf programs; efforts to eliminate product overlap with fund mergers; ongoing services to manage leverage that has become increasingly complex; periodic evaluation of share repurchases and other support initiatives for certain BlackRock funds; and continued communications efforts with shareholders, fund analysts and financial advisers. With respect to the latter, the Independent Board Members noted BlackRock’s continued commitment to supporting the secondary market for the common shares of its closed-end funds through a comprehensive secondary market communication program designed to raise investor and analyst awareness and understanding of closed-end funds. BlackRock’s support services included, among other things: continuing communications concerning the redemption efforts related to AMPS; sponsoring and participating in conferences; communicating with closed-end fund analysts covering the BlackRock funds throughout the year; providing marketing and product updates for the closed-end funds; and maintaining and enhancing its closed-end fund website.

Conclusion

Each Board, including the Independent Board Members, unanimously approved the continuation of the Advisory Agreement between the Manager and the Trust for a one-year term ending June 30, 2018. The Board of each of BGR and BCX, including the Independent Board Members, also unanimously approved the continuation of the Sub-Advisory Agreement between the Manager and the Sub-Advisor, with respect to its Trust, for a one-year term ending June 30, 2018.

Based upon its evaluation of all of the aforementioned factors in their totality, as well as other information, each Board, including the Independent Board Members, was satisfied that the terms of the Agreement(s) were fair and reasonable and in the best interest of the Trust and its shareholders. In arriving at its decision to approve the Agreement(s), each Board did not identify any single factor or group of factors as, all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination. The contractual fee arrangements for each Trust reflect the results of several years of review by the Trust’s Board Members and predecessor Board Members, and discussions between such Board Members (and predecessor Board Members) and BlackRock. As a result, the Board Members’ conclusions may be based in part on their consideration of these arrangements in prior years.

Disclosure of Sub-Advisory Agreement |  |

The Board of Directors or Trustees, as applicable (each, a “Board,” collectively, the “Boards,” and the members of which are referred to as “Board Members”), of BOE, BGY and BUI met in person on March 1, 2017 (the “March Meeting”) to consider the initial approval of the proposed sub-advisory agreement (the “Sub-Advisory Agreement”) among BlackRock Advisors, LLC (the “Manager”), each Trust’s investment adviser, BlackRock International Limited (the “Sub-Advisor”), and the Trust.

On the date of the March Meeting, the Board of each Trust consisted of eleven individuals, nine of whom were not “interested persons” of the Trust as defined in the Investment Company Act of 1940, as amended (the “1940 Act”) (the “Independent Board Members”). Pursuant to the 1940 Act, each Board is required to consider the initial approval of its Trust’s Sub-Advisory Agreement.

The Board previously met in person on April 28, 2016 (the “April 2016 Meeting”) and on June 9 and 10, 2016 (the “June 2016 Meeting”) to consider the approval of each Trust’s investment advisory agreement with the Manager (the “Advisory Agreement”). At the June 2016 Meeting, the Board, including the independent board members, unanimously approved the continuation of the Advisory Agreement for a one-year term ending June 30, 2017. A discussion of the basis for the Board’s approval of the Advisory Agreement at the June 2016 Meeting is included in the semi-annual shareholder report of each Trust for the period ended June 30, 2016.

At the March Meeting, the Board of each Trust reviewed materials relating to its consideration of the Sub-Advisory Agreement. The factors considered by the Board at the March Meeting in connection with approval of the proposed Sub-Advisory Agreement were substantially the same as the factors considered at the April 2016 Meeting and the June 2016 Meeting with respect to approval of the Advisory Agreement. The Board of each Trust also considered additional factors, including that its Trust will continue to be charged the same investment advisory fee as stated in its investment management agreement with the Manager and that there will be no additional fees charged to its Trust related to the proposed Sub-Advisory Agreement, that the proposed Sub-Advisory Agreement with the Sub-Advisor is substantially similar to comparable subadvisory agreements for other BlackRock closed-end funds, that the principal differences between the proposed Sub-Advisory Agreement and the Advisory Agreement are revisions designed to reflect the sub-advisory nature of the relationship, and that the proposed Sub-Advisor’s personnel who would be providing investment advice to its Trust are subject to the same compliance and reporting infrastructure as the personnel of the Manager providing investment advice to the Trust.

Following discussion, the Board of each Trust, including a majority of the Independent Board Members, approved the Sub-Advisory Agreement between the Manager and the Sub-Advisor with respect to the Trust for a two-year term beginning on the effective date of the Sub-Advisory Agreement. Based upon its evaluation of all of the aforementioned factors in their totality, the Board, including a majority of the Independent Board Members, was satisfied that the terms of the Sub-Advisory Agreement were fair and reasonable and in the best interest of the Trust and its shareholders. In arriving at its decision to approve the Sub-Advisory Agreement, the Board did not identify any single factor or group of factors as all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination.

Additional Information |  |

General Information

The Trusts 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 have not been updated after completion of the respective Trust’s offerings and the information contained in each Trust’s Statement of Additional Information may have become outdated.

BME’s Statement of Additional Informational includes additional 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. Other than as described on page 130, 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.

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

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.

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.

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

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 Fund, 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.

(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 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 a portfolio manager 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. Such portfolio managers may therefore be entitled to receive a portion of any incentive fees earned on such accounts. Currently, the portfolio managers of this fund are not entitled to receive a portion of incentive fees of other 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.

Portfolio Manager Compensation Overview

The discussion below describes the portfolio managers’ compensation as of June 30, 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.

3

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

Discretionary Incentive Compensation

Mr. Burnside

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 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 this portfolio manager, such benchmarks for the Fund and other accounts are:

Portfolio Manager |  | Benchmarks
Todd Burnside |  | Russell 1000 Index (Gross Total Return); S&P 500 Index; FTSE North America in GBP; MSCI Developed - US Net TR Index; FTSE United States in GBP; 60% S&P 500, 20% S&P TSX and 20% Mexico IPC (USD); Russell 1000, expressed in EUR; Russell 1000 Growth Index; Russell 1000 Value Index (Total Return); Morningstar US Flex-Cap Equity Classification; Morningstar Large Blend Classification; Morningstar Investment Association North America Classification; Morningstar Large Growth Classification; Morningstar Large Value Classification; LIPPER Options Arbitrage/Opt Strategies Funds Classification

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.

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.

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

4

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. All of the eligible portfolio managers.
