Total Returns as of April 30, 2012

For the six months ended April 30, 2012, the Trust returned 21.03% based on market price and 5.20% based on NAV. For the same period, the closed-end Lipper Sector Equity Funds category posted an average return of 13.14% based on market price and 7.46% based on NAV. All returns reflect reinvestment of dividends. The Trust moved from a discount to NAV to a premium by period end, which accounts for the difference between performance based on price and performance based on NAV. The following discussion relates to performance based on NAV.

During the period, the water resources segment of the portfolio generated the highest positive contribution to the Trust’s performance. The strong performance of this segment was driven primarily by positions in two Brazilian-based water utility companies. The continuing growth of the middle class and more clarity on regulation continues to drive the need for better water quality and sewerage systems in developing countries. The Trust’s holding of Manila Water Co., Inc. (Philippines) also delivered a notable return as a result of strong demand for the company’s services. Additionally, the Trust benefited from holding multinational industrial manufacturer Pentair, Inc. (United States), which announced at the end of March that it would be combining with Tyco International Ltd.’s flow-control business.

In the agriculture segment of the portfolio, exposure to equipment companies contributed positively to performance, as improving investor sentiment drove these names higher. For example, in late 2011 portfolio holding Deere & Co. (United States) provided investors with more transparency into its order book for 2012, which helped to build confidence in the company’s outlook for the forthcoming year and resulted in strong performance. In addition, the Trust’s option writing strategy had a positive impact on performance.

Detracting from relative performance was the Trust’s exposure, although limited, to renewable energy technologies such as Vestas Wind Systems A/S (Denmark) and First Solar, Inc. (United States). The outlook for these companies became clouded by increased government austerity, particularly in European markets. The Trust’s exposure in this space was focused on cost, technology and market leaders.

Also having a negative impact on returns were holdings of companies involved in the production and distribution of fertilizers. These names were challenged during the period due to uncertainty about whether Chinese and Indian buyers would commit to contracts for the first half of 2012, which led major fertilizer producers to cut their forecasts and, therefore, put downward pressure on the industry.

During the six-month period, the Trust initiated a position in Novozymes A/S (Denmark) in the new energy segment of the portfolio. Novozymes A/S appears to be well-positioned to benefit from increasing demand for enzymes as a result of the start-up of second-generation biofuel plants over the medium to long term.

In the water resources space, the Trust added two new holdings of US-based multinational water technology companies, Pall Corp. and Xylem, Inc., the latter of which was spun off from the break-up of ITT Corp. The Trust also received shares of water, hygiene and energy technology company Ecolab, Inc. (United States) as a result of its takeover of Nalco Holding Co. (United States).

During the period, the Trust held an elevated level of cash as a means of defensive positioning due to near-term uncertainty about the market outlook. The cash balance did not have a material impact on the Trust’s performance.

As of period end, the Trust continued to hold large allocations to both the agriculture and water resources segments and less emphasis on new energy. The Trust maintained its large allocation to agriculture based on management’s view that recent improving profitability in the agriculture sector raises the potential for increased spending on farming inputs. Within the agriculture segment, the Trust’s holdings reflected a preference for agricultural science companies, agricultural equipment makers and fertilizer producers. The Trust maintained its heavy exposure to water resources as these strong dividend-paying stocks have benefited from investors’ increased demand for yield in a low interest rate environment coupled with heightened merger and acquisition activity within the space. The Trust’s water resources holdings reflected a preference for companies with exposure to infrastructure, desalination and technologies for water management.

For the six months ended April 30, 2012, the Trust returned (0.40)% based on market price and 0.82% based on NAV. For the same period, the closed-end Lipper Sector Equity Funds category posted an average return of 13.14% based on market price and 7.46% based on NAV. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The following discussion relates to performance based on NAV.

The strongest contribution to returns for the period came from the Trust’s exposure to names in the oil, gas & consumable fuels industry, particularly within the oil & gas storage & transportation group. Notable individual performers included Cheniere Energy, Inc., MarkWest Energy Partners LP and Plains All American Pipeline LP. The Trust’s option-writing strategy, particularly in the oil & gas exploration & production group, also had a positive impact on returns. In the energy equipment & services industry, select holdings within oil & gas equipment & services boosted returns.

The largest detractor from the Trust’s performance was exposure to coal-related equities in the oil, gas & consumable fuels industry. As natural gas prices fell, it became more economical for utility companies to generate

electricity using natural gas rather than coal. This trend resulted in excess thermal coal inventories and pushed spot coal prices to their lowest level in several years. Even after declining more than 40% in 2011, US coal producers shed an additional 15% during the first quarter of 2012. In this space, the Trust’s holdings of Alpha Natural Resources, Inc., Consol Energy, Inc. and Peabody Energy Corp. all posted losses for the period. Within the oil & gas exploration & production group, losses from the Trust’s exposure to natural gas offset the gains from its oil-related holdings. Notable detractors with natural gas exposure included Crew Energy, Inc., EQT Corp. and Southwestern Energy Co.

During the six-month period, the Trust increased its allocation within the oil, gas & consumable fuels industry to refiners and storage & transportation names, while trimming exposure to integrated oil & gas and exploration & production names as well as oil & gas equipment services.

At the end of the period, the Trust’s largest portfolio concentrations were in the oil & gas exploration & production, oil & gas storage & transportation and oil & gas equipment & services groups. The Trust continued to favor oil producers across the market-capitalization spectrum and maintained exposure to coal and low-cost natural gas producers that have come under selling pressure in recent months.

On February 27, 2012, the Trust acquired substantially all of the assets and substantially all of the liabilities of the BlackRock Equity Dividend Trust and BlackRock Strategic Equity Dividend Trust in exchange for newly issued shares of the Trust.

For the six months ended April 30, 2012, the Trust returned 8.70% based on market price and 10.29% based on NAV. For the same period, the Russell 1000^® Value Index returned 11.62%. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The following discussion of relative performance based on NAV pertains to the Russell 1000^® Value Index.

The Trust’s sector underweight and stock selection within financials detracted from performance relative to the Russell 1000^® Value Index, as did stock selection in the industrials sector. Also having a negative impact was an underweight and selection in the health care sector, stock selection and a marginal overweight in telecommunications services, and stock selection and an underweight in consumer discretionary.

Contributing positively to performance during the period was a combination of stock selection and a marginal overweight in energy, stock selection in consumer staples, and an overweight in the industrials sector. Stock selection and an underweight within information technology (“IT”) boosted returns during the period, as did an overweight in the materials sector. The Trust’s option writing strategy had a positive impact on performance.

During the six-month period, the Trust made relatively few material changes to portfolio holdings or allocations. However, given positive structural changes within the financials sector and a gradually improving

regulatory front, the Trust added to some existing positions within the sector. Additionally, the Trust sought to reduce exposure to companies with higher portions of their revenues coming from the euro zone.

As of period end, the Trust was positioned to benefit from a recovering global economy, with a specific focus on sectors tied closely to accelerating consumption and demand around the world. While US multinational companies have had the backing of a strong domestic equity market and the benefit of gradually improving US consumer sentiment, the emerging markets remain critically important for future revenue growth. Trust management believes these markets will be a primary driver of equity returns, either directly or indirectly, in the years to come. Companies that have made a clear effort to expand operations in emerging- market regions in order to grow their brand recognition and overall foot- print are most likely to be the early beneficiaries of growth in these markets. This view is most clearly reflected by the Trust’s relatively larger allocations to the materials, industrials, consumer staples and energy sectors. Additionally, improving fundamentals within financials increases the potential for the sector to participate when world markets eventually garner confidence.

The Trust remains less invested in IT, health care, and consumer discretionary; however, Trust management believes these sectors will ultimately become more important for dividend investing in the future as high-growth companies become stable-growth companies generating more established revenue streams. In the aggregate, while the Trust’s portfolio of holdings is purposefully structured to withstand near-term market corrections, it is also poised to compete on the upside when company fundamentals become a more visible driver of equity returns in the market.

For the six months ended April 30, 2012, the Trust returned 10.24% based on market price and 5.91% based on NAV. For the same period, the MSCI All Country World Index posted a return of 7.07%. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which narrowed during the period, accounts for the difference between performance based on price and performance based on NAV. The following discussion relates to performance based on NAV.

The Trust’s average cash position, which was higher than usual during the period as a means to reduce the impact of market volatility, detracted from performance as investor sentiment improved at the end of 2011 and equity markets were further supported by accommodative policy action in the first quarter of 2012. Also having a negative impact on returns was stock selection in consumer discretionary, where the Trust’s holdings in restaurants and auto manufacturers were the primary detractors. In the information technology (“IT”) sector, stock selection across all three industry groups, including semiconductors, software and hardware, hurt performance.

The largest contributor to performance for the period was stock selection in the industrials sector, where a bias toward US-based industrial machinery companies, including SPX Corp., Stanley Black & Decker, Inc. and Dover Corp., had a positive impact on returns. The Trust’s sector

underweight relative to the MSCI All Country World Index in materials proved beneficial as the sector continued to face headwinds due to sluggish global economic growth. In addition, the Trust’s option overwrites on approximately half of its portfolio holdings had a positive impact on returns.

During the six-month period, the Trust increased exposure to the industrials sector by closing its underweight in capital goods. The Trust also increased its weighting in consumer discretionary, specifically within retailers. The Trust reduced its holdings in consumer staples and integrated telecommunication services stocks. From a regional perspective, the Trust trimmed exposure to Europe and added exposure to the United States.

At period end, the Trust’s positioning reflected several key characteristics. For one, given the number of headwinds faced by equity markets and the potential severity of the risks they impose, the Trust’s holdings were diversified in a manner that reduces the Trust’s vulnerability to any particular development or macro event. Additionally, the Trust’s holdings did not reflect an intentional bias toward any particular sector or security characteristic. The Trust’s overall portfolio risk was derived more from the individual security risks associated with its holdings than from systematic risks (i.e., risks that impact an entire market or market segment).

For the six months ended April 30, 2012, the Trust returned 16.59% based on market price and 10.55% based on NAV. For the same period, the Russell 3000^® Healthcare Index returned 14.27%. All returns reflect reinvestment of dividends. The Trust moved from a discount to NAV to a premium by period end, which accounts for the difference between performance based on price and performance based on NAV. The following discussion relates to performance based on NAV.

Detracting from performance relative to the Russell 3000^® Healthcare Index was stock selection in pharmaceuticals. Although large-cap pharmaceutical stocks have largely benefited from investors’ search for non-cyclical equities during the risk-off trading periods in the market over the past year, the Trust’s exposure to European-based pharmaceuticals, which are not represented in the Russell 3000^® Healthcare Index, hurt performance as uncertainty in Europe and talks of further drug pricing cuts dragged share prices down in that space. Additionally, an overweight to health care distributors had a negative impact on the Trust’s performance as deliberations surrounding the constitutionality of the new US health care legislation weighed on companies most sensitive to industry volumes.

Given evidence of decelerating health care spending in the United States and continued pricing pressures in Europe, the Trust sought to avoid companies that were more vulnerable to these trends in favor of companies that offered strong growth potential from product innovation or attractive pipeline potential. This preference resulted in an overweight to biotechnology, which was the strongest performing health care industry for the period. Also contributing positively to performance was stock selection in health care technology and an underweight to the health

care equipment sub-industry. The Trust’s option writing strategy had a positive impact on performance.

During the six-month period, the Trust sought opportunities in health care segments that are less vulnerable to reimbursement pressures and companies that are introducing enticing new products. As a result, the Trust rotated out of select procedural-based health care equipment and service names and increased exposure to areas that offer better growth potential, such as biopharmaceuticals, dental supply companies, eye care companies and animal health names. At times, the Trust’s cash balance was elevated when selling activity exceeded purchasing. The Trust’s cash position did not have a material impact on performance during the period.

As of period end, the Trust’s most significant industry allocations were in pharmaceuticals (30%), biotechnology (25%), health care providers & services (20%) and health care equipment & supplies (18%), with the balance invested across various areas of health care sector.

Amid unresolved global macroeconomic issues and the overhang of the final US Supreme Court ruling on the constitutionality of the new health care legislation, the Trust continues to focus on innovative companies that offer products or services that satisfy an unmet medical need or significantly reduce the costs associated with a current product or procedure. The Trust seeks to identify and own companies that have a strong outlook, even in a weak macroeconomic environment, due to new product cycles, strong execution and/ or margin opportunities. The Trust also continues to selectively add to its holdings of companies with overly depressed valuations and favorable risk/reward characteristics.

For the six months ended April 30, 2012, the Trust returned 5.40% based on market price and 4.99% based on NAV. For the same period, the MSCI All Country World Index ex-US returned 2.73%. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which narrowed during the period, accounts for the difference between performance based on price and performance based on NAV. The following discussion relates to performance based on NAV.

Relative to the MSCI All Country World Index ex-US, the Trust’s positive performance came largely from stock selection in the utilities, materials, information technology (“IT”) and financials sectors. In utilities, the Trust’s positioning within electric utilities benefited performance, where Cia Energetica de Minas Gerais significantly outperformed its competitors. In materials, the Trust’s holdings in the metals & mining industry, particularly Xstrata Plc and Quadra FNX Mining Ltd., boosted returns. In IT, the Trust’s overweight in software stocks enhanced returns during the period. Within financials, stock selection in the insurance and capital markets industries had a positive impact on performance. In addition, the Trust’s option overwrites on approximately half of its portfolio holdings had a positive impact on returns.

The Trust’s average cash position, which was higher than usual during the period as a means to reduce the impact of market volatility, detracted

from performance as investor sentiment improved at the end of 2011 and equity markets were further supported by accommodative policy action in the first quarter of 2012. Also having a negative impact on returns was stock selection in consumer discretionary, where the Trust’s holdings in auto manufacturers were the primary detractors.

During the six-month period, the Trust increased exposure to the industrials sector by closing its underweight in capital goods. The Trust increased its allocation to materials by increasing exposure to fertilizers, gold and paper products. The Trust also increased its weighting in consumer discretionary, particularly within retailers. These additions were offset by reductions in consumer staples and telecommunications services.

At period end, the Trust’s positioning reflected several key characteristics. For one, given the number of headwinds faced by equity markets and the potential severity of the risks they impose, the Trust’s holdings were diversified in a manner that reduces the Trust’s vulnerability to any particular development or macro event.

For the six months ended April 30, 2012, the Trust returned 4.51% based on market price and 1.49% based on NAV. For the same period, the closed-end Lipper Sector Equity Funds category posted an average return of 13.14% based on market price and 7.46% based on NAV. All returns reflect reinvestment of dividends. The Trust’s discount to NAV, which narrowed during the period, accounts for the difference between performance based on price and performance based on NAV. The following discussion relates to performance based on NAV.

The largest contribution to the Trust’s performance came from the basic materials segment of the portfolio, where the Trust benefited from its holdings in chemicals, machinery, including Deere & Co. and Caterpillar, Inc., paper products, including International Paper Co. and MeadWestvaco Corp., and industrial gas name Praxair, Inc.

In the natural resources segment (metals & mining), the weak global macroeconomic outlook and fragile investor sentiment resulted in a volatile and generally weak period for mining stocks. However, the Trust’s holding in Mexican silver producer Industrias Penoles SAB de CV posted strong gains as the company continued to deliver on its operational and financial objectives. Positions in mining majors BHP Billiton Plc and Rio Tinto Plc were also notable contributors as these large-cap companies proved more resilient during the “risk-off” periods in the market as compared to their mid-tier counterparts.

In the energy segment, the Trust’s oil-related holdings in the oil & gas exploration & production group, including Whiting Petroleum Corp. and EOG Resources, Inc., delivered strong returns; however, their impact on Trust performance was muted by exposure to natural gas producers, which suffered from falling prices of natural gas during the period. In addition, the Trust’s option writing strategy had a positive impact on performance.

Detracting from performance in the energy segment of the portfolio was the Trust’s exposure to coal in the oil, gas & consumable fuels industry. Demand for coal weakened significantly during the period due to the relatively mild winter and utility companies switching to lower-cost natural gas. Even after declining more than 40% in 2011, US coal producers shed an additional 15% during the first quarter of 2012.

Within metals & mining, the Trust’s exposure to precious metals detracted from returns. Gold equities generally underperformed the broader metals & mining industry and some of the Trust’s holdings of gold producers detracted from performance as a result.

During the six-month period, the Trust increased exposure in its metals & mining segment to gold equities upon their underperformance relative to bullion. In particular, the Trust initiated positions in Eldorado Gold Corp. and Kinross. In the basic materials segment of the portfolio, the Trust added to holdings in fertilizers, industrial gasses and steel companies while trimming positions in chemicals and paper & forest products. In the energy segment, the Trust added to integrated oil & gas names, refiners and storage & transportation, while trimming exposure to the oil & gas exploration & production and equipment & services groups.

At the end of the period, the Trust held approximately 43% of total managed assets in metals & mining stocks, comprised of both base metals (28%) and precious metals (15%). The Trust’s allocation to the energy sector (33%) was heavily weighted in the oil & gas exploration & production group, with smaller weightings in the integrated oil & gas, oil & gas equipment & services and coal & consumable fuels groups. The basic materials segment of the portfolio (23%) was allocated heavily to chemicals with smaller exposures to the paper & forest products and machinery industries.
