The Gabelli Global Utility & Income Trust

Notes to Financial Statements (Unaudited)

1. Organization. The Gabelli Global Utility & Income Trust (the “Fund”) is a non-diversified closed-end management investment company organized as a Delaware statutory trust on March 8, 2004 and registered under the Investment Company Act of 1940, as amended (the “1940 Act”). Investment operations commenced on May 28, 2004.

The Fund’s investment objective is to seek a consistent level of after-tax total return over the long term with an emphasis currently on qualified dividends. The Fund will attempt to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in equity securities (including preferred securities) of domestic and foreign companies involved to a substantial extent in providing products, services, or equipment for the generation or distribution of electricity, gas, or water and infrastructure operations, and in equity securities (including preferred securities) of companies in other industries, in each case in such securities that are expected to pay periodic dividends.

2. Significant Accounting Policies. As an investment company, the Fund follows the investment company accounting and reporting guidance, which is part of U.S. generally accepted accounting principles (“GAAP”) that may require the use of management estimates and assumptions in the preparation of its financial statements. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

Security Valuation. Portfolio securities listed or traded on a nationally recognized securities exchange or traded in the U.S. over-the-counter market for which market quotations are readily available are valued at the last quoted sale price or a market’s official closing price as of the close of business on the day the securities are being valued. If there were no sales that day, the security is valued at the average of the closing bid and asked prices or, if there were no asked prices quoted on that day, then the security is valued at the closing bid price on that day. If no bid or asked prices are quoted on such day, the security is valued at the most recently available price or, if the Board of Trustees (the “Board”) so determines, by such other method as the Board shall determine in good faith to reflect its fair market value. Portfolio securities traded on more than one national securities exchange or market are valued according to the broadest and most representative market, as determined by Gabelli Funds, LLC (the “Adviser”).

Portfolio securities primarily traded on a foreign market are generally valued at the preceding closing values of such securities on the relevant market, but may be fair valued pursuant to procedures established by the Board if market conditions change significantly after the close of the foreign market, but prior to the close of business on the day the securities are being valued. Debt obligations for which market quotations are readily available are valued at the average of the latest bid and asked prices. If there were no asked prices quoted on such day, the security is valued using the closing bid price, unless the Board determines such amount does not reflect the securities’ fair value, in which case these securities will be fair valued as determined by the Board. Certain securities are valued principally using dealer quotations. Futures contracts are valued at the closing settlement price of the exchange or board of trade on which the applicable contract is traded. OTC futures and options on futures for which market quotations are readily available will be valued by quotations received from a pricing service or, if no quotations are available from a pricing service, by quotations obtained from one or more dealers in the instrument in question by the Adviser.

Securities and assets for which market quotations are not readily available are fair valued as determined by the Board. Fair valuation methodologies and procedures may include, but are not limited to: analysis and review of available financial and non-financial information about the company; comparisons with the valuation and

13

Notes to Financial Statements (Unaudited) (Continued)

changes in valuation of similar securities, including a comparison of foreign securities with the equivalent U.S. dollar value American Depositary Receipt securities at the close of the U.S. exchange; and evaluation of any other information that could be indicative of the value of the security.

The inputs and valuation techniques used to measure fair value of the Fund’s investments are summarized into three levels as described in the hierarchy below:

● Level 1 — quoted prices in active markets for identical securities;

● Level 2 — other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.); and

● Level 3 — significant unobservable inputs (including the Board’s determinations as to the fair value of investments).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input both individually and in the aggregate that is significant to the fair value measurement. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The summary of the Fund’s investments in securities and other financial instruments by inputs used to value the Fund’s investments as of June 30, 2017 is as follows:

* Other financial instruments are derivatives reflected in the SOI, such as options, futures, forwards, and swaps, which may be valued at the unrealized appreciation/depreciation    of the instrument.

The Fund did not have material transfers among Level 1, Level 2, and Level 3 during the six months ended June 30, 2017. The Fund’s policy is to recognize transfers among Levels as of the beginning of the reporting period.

Additional Information to Evaluate Qualitative Information.

General. The Fund uses recognized industry pricing services – approved by the Board and unaffiliated with the Adviser – to value most of its securities, and uses broker quotes provided by market makers of securities not valued by these and other recognized pricing sources. Several different pricing feeds are received to value domestic equity securities, international equity securities, preferred equity securities, and fixed income securities. The data within these feeds are ultimately sourced from major stock exchanges and trading systems where these securities trade. The prices supplied by external sources are checked by obtaining quotations or actual transaction prices from market participants. If a price obtained from the pricing source is deemed unreliable, prices will be sought from another pricing service or from a broker/dealer that trades that security or similar securities.

Fair Valuation. Fair valued securities may be common or preferred equities, warrants, options, rights, or fixed income obligations. Where appropriate, Level 3 securities are those for which market quotations are not available, such as securities not traded for several days, or for which current bids are not available, or which are restricted as to transfer. When fair valuing a security, factors to consider include recent prices of comparable securities that are publicly traded, reliable prices of securities not publicly traded, the use of valuation models, current analyst reports, valuing the income or cash flow of the issuer, or cost if the preceding factors do not apply. A significant change in the unobservable inputs could result in a lower or higher value in Level 3 securities. The circumstances of Level 3 securities are frequently monitored to determine if fair valuation measures continue to apply.

The Adviser reports quarterly to the Board the results of the application of fair valuation policies and procedures. These may include backtesting the prices realized in subsequent trades of these fair valued securities to fair values previously recognized.

Derivative Financial Instruments. The Fund may engage in various portfolio investment strategies by investing in derivative financial instruments for the purposes of increasing the income of the Fund, hedging against changes

15

The Gabelli Global Utility & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

in the value of its portfolio securities and in the value of securities it intends to purchase, or hedging against a specific transaction with respect to either the currency in which the transaction is denominated or another currency. Investing in certain derivative financial instruments, including participation in the options, futures, or swap markets, entails certain execution, liquidity, hedging, tax, and securities, interest, credit, or currency market risks. Losses may arise if the Adviser’s prediction of movements in the direction of the securities, foreign currency, and interest rate markets is inaccurate. Losses may also arise if the counterparty does not perform its duties under a contract, or, in the event of default, the Fund may be delayed in or prevented from obtaining payments or other contractual remedies owed to it under derivative contracts. The creditworthiness of the counterparties is closely monitored in order to minimize these risks. Participation in derivative transactions involves investment risks, transaction costs, and potential losses to which the Fund would not be subject absent the use of these strategies. The consequences of these risks, transaction costs, and losses may have a negative impact on the Fund’s ability to pay distributions.

Collateral requirements differ by type of derivative. Collateral requirements are set by the broker or exchange clearing house for exchange traded derivatives, while collateral terms are contract specific for derivatives traded over-the-counter. Securities pledged to cover obligations of the Fund under derivative contracts are noted in the Schedule of Investments. Cash collateral, if any, pledged for the same purpose will be reported separately in the Statement of Assets and Liabilities.

The Fund’s policy with respect to offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master agreement does not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

The Fund’s derivative contracts held at June 30, 2017 are not accounted for as hedging instruments under GAAP and are disclosed in the Schedule of Investments together with the related counterparty.

Swap Agreements. The Fund may enter into equity contract for difference swap transactions for the purpose of increasing the income of the Fund. The use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. In an equity contract for difference swap, a set of future cash flows is exchanged between two counterparties. One of these cash flow streams will typically be based on a reference interest rate combined with the performance of a notional value of shares of a stock. The other will be based on the performance of the shares of a stock. Depending on the general state of short term interest rates and the returns on the Fund’s portfolio securities at the time an equity contract for difference swap transaction reaches its scheduled termination date, there is a risk that the Fund will not be able to obtain a replacement transaction or that the terms of the replacement will not be as favorable as on the expiring transaction.

Unrealized gains related to swaps are reported as an asset and unrealized losses are reported as a liability in the Statement of Assets and Liabilities. The change in value of swaps, including the accrual of periodic amounts of interest to be received or paid on swaps, is reported as unrealized gain or loss in the Statement of Operations. A realized gain or loss is recorded upon receipt or payment of a periodic payment or termination of swap agreements.

Notes to Financial Statements (Unaudited) (Continued)

The Fund has entered into equity contract for difference swap agreements with The Goldman Sachs Group, Inc. Details of the swaps at June 30, 2017 are reflected within the Schedule of Investments and further details are as follows:

Notional Amount	Equity Security Received	Interest Rate/ Equity Security Paid	Termination Date		Net Unrealized Appreciation/(Depreciation)
	Market Value Appreciation on:	One month LIBOR plus 90 bps plus Market Value Depreciation on:
$599,215 (50,000 Shares)	Rolls-Royce Holdings plc	Rolls-Royce Holdings plc		06/28/18		$(19,112)
$    4,615 (3,550,000 Shares)	Rolls-Royce Holdings plc, Cl. C	Rolls-Royce Holdings plc, Cl. C		06/28/18		9
						$(19,103)

The Fund’s volume of activity in equity contract for difference swap agreements during the six months ended June 30, 2017 had an average monthly notional amount of approximately $497,183.

As of June 30, 2017, the value of equity contract for difference swap agreements can be found in the Statement of Assets and Liabilities under Assets, Unrealized appreciation on swap contracts and under Liabilities, Unrealized depreciation on swap contracts. For the six months ended June 30, 2017, the effect of equity contract for difference swap agreements can be found in the Statement of Operations under Net Realized and Unrealized Gain/(Loss) on Investments, Swap Contracts, and Foreign Currency, Net realized gain on swap contracts and Net change in unrealized appreciation/depreciation on swap contracts.

Forward Foreign Exchange Contracts. The Fund may engage in forward foreign exchange contracts for the purpose of hedging a specific transaction with respect to either the currency in which the transaction is denominated or another currency as deemed appropriate by the Adviser. Forward foreign exchange contracts are valued at the forward rate and are marked-to-market daily. The change in market value is included in unrealized appreciation/depreciation on foreign currency translations. When the contract is closed, the Fund records a realized gain or loss 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 forward foreign exchange contracts does not eliminate fluctuations in the underlying prices of the Fund’s portfolio securities, but it does establish a rate of exchange that can be achieved in the future. Although forward foreign exchange contracts limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase. There were no forward foreign exchange contracts outstanding at June 30, 2017. The Fund’s volume of activity in forward foreign exchange contracts during the six months ended June 30, 2017 had an average monthly notional amount of approximately $3,500,000, while outstanding.

For the six months ended June 30, 2017, the effect of forward foreign exchange contracts can be found in the Statement of Operations under Net Realized and Unrealized Gain/(Loss) on Investments, Swap Contracts, and Foreign Currency, Net realized loss on foreign currency transactions and Net change in unrealized appreciation/depreciation on foreign currency translations.

Limitations on the Purchase and Sale of Futures Contracts, Certain Options, and Swaps. Subject to the guidelines of the Board, the Fund may engage in “commodity interest” transactions (generally, transactions in futures, certain options, certain currency transactions, and certain types of swaps) only for bona fide hedging or other permissible transactions in accordance with the rules and regulations of the Commodity Futures Trading Commission (“CFTC”). Pursuant to amendments by the CFTC to Rule 4.5 under the Commodity Exchange Act (“CEA”), the Adviser has filed a notice of exemption from registration as a “commodity pool operator” with respect to the Fund. The Fund and the Adviser are therefore not subject to registration or regulation as a commodity pool operator under the CEA. In addition, certain trading restrictions are now applicable to the Fund as of January 1, 2013. These trading restrictions permit the Fund to engage in commodity interest transactions that include (i) “bona fide hedging” transactions, as that term is defined and interpreted by the CFTC and its staff, without regard to the percentage of the Fund’s assets committed to margin and options premiums and (ii) non-bona fide hedging transactions, provided that the Fund does not enter into such non-bona fide hedging transactions if, immediately thereafter, either (a) the sum of the amount of initial margin deposits on the Fund’s existing futures positions or swaps positions and option or swaption premiums would exceed 5% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions, or (b) the aggregate net notional value of the Fund’s commodity interest transactions would not exceed 100% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions. Therefore, in order to claim the Rule 4.5 exemption, the Fund

18

The Gabelli Global Utility & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

is limited in its ability to invest in commodity futures, options, and certain types of swaps (including securities futures, broad based stock index futures, and financial futures contracts). As a result, in the future the Fund will be more limited in its ability to use these instruments than in the past, and these limitations may have a negative impact on the ability of the Adviser to manage the Fund, and on the Fund’s performance.

Foreign Currency Translations. The books and records of the Fund are maintained in U.S. dollars. Foreign currencies, investments, and other assets and liabilities are translated into U.S. dollars at current exchange rates. Purchases and sales of investment securities, income, and expenses are translated at the exchange rate prevailing on the respective dates of such transactions. Unrealized gains and losses that result from changes in foreign exchange rates and/or changes in market prices of securities have been included in unrealized appreciation/depreciation on investments and foreign currency translations. Net realized foreign currency gains and losses resulting from changes in exchange rates include foreign currency gains and losses between trade date and settlement date on investment securities transactions, foreign currency transactions, and the difference between the amounts of interest and dividends recorded on the books of the Fund and the amounts actually received. The portion of foreign currency gains and losses related to fluctuation in exchange rates between the initial purchase trade date and subsequent sale trade date is included in realized gain/(loss) on investments.

Foreign Securities. The Fund may directly purchase securities of foreign issuers. Investing in securities of foreign issuers involves special risks not typically associated with investing in securities of U.S. issuers. The risks include possible revaluation of currencies, the inability to repatriate funds, less complete financial information about companies, and possible future adverse political and economic developments. Moreover, securities of many foreign issuers and their markets may be less liquid and their prices more volatile than securities of comparable U.S. issuers.

Foreign Taxes. The Fund may be subject to foreign taxes on income, gains on investments, or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Restricted Securities. The Fund is not subject to an independent limitation on the amount it may invest in securities for which the markets are restricted. Restricted securities include securities whose disposition is subject to substantial legal or contractual restrictions. The sale of restricted securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than the sale of securities eligible for trading on national securities exchanges or in the over-the-counter markets. Restricted securities may sell at a price lower than similar securities that are not subject to restrictions on resale. Securities freely saleable among qualified institutional investors under special rules adopted by the SEC may be treated as liquid if they satisfy liquidity standards established by the Board. The continued liquidity of such securities is not as well assured as that of publicly traded securities, and, accordingly, the Board will monitor their liquidity. At June 30, 2017, the Fund held no restricted securities.

Securities Transactions and Investment Income. Securities transactions are accounted for on the trade date with realized gain/(loss) on investments determined by using the identified cost method. Interest income (including amortization of premium and accretion of discount) is recorded on the accrual basis. Premiums and discounts on debt securities are amortized using the effective yield to maturity method. Dividend income is recorded on

19

The Gabelli Global Utility & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

the ex-dividend date, except for certain dividends from foreign securities that are recorded as soon after the ex-dividend date as the Fund becomes aware of such dividends.

Distributions to Shareholders. Distributions to shareholders are recorded on the ex-dividend date. Distributions to shareholders are based on income and capital gains as determined in accordance with federal income tax regulations, which may differ from income and capital gains as determined under GAAP. These differences are primarily due to differing treatments of income and gains on various investment securities and foreign currency transactions held by the Fund, and timing differences. Distributions from net investment income for federal income tax purposes include net realized gains on foreign currency transactions. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, adjustments are made to the appropriate capital accounts in the period when the differences arise. These reclassifications have no impact on the NAV of the Fund.

The tax character of distributions paid during the year ended December 31, 2016 was as follows:

	Common		Preferred
Distributions paid from:
Ordinary income (inclusive of short term gains)	$	2,520,340	$	998,676
Net long term capital gains		1,906,992		755,640
Return of capital		506,224		—
Total distributions paid	$	4,933,556	$	1,754,316

Provision for Income Taxes. The Fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). It is the policy of the Fund to comply with the requirements of the Code applicable to regulated investment companies and to distribute substantially all of its net investment company taxable income and net capital gains. Therefore, no provision for federal income taxes is required.

At December 31, 2016, the components of accumulated earnings/losses on a tax basis were as follows:

Net unrealized appreciation on investments, swap contracts, and foreign currency translations.	$	20,295,615
Other temporary differences*		(27,077	)
Total.	$	20,268,538

* Other temporary differences were primarily due to current year dividends payable.

The following summarizes the tax cost of investments and the related net unrealized appreciation at June 30, 2017:

	Cost		Gross Unrealized Appreciation		Gross Unrealized Depreciation			Net Unrealized Appreciation
Investments	$	110,609,891	$	34,138,896	$	(5,398,628	)	$	28,740,268

The Fund is required to evaluate tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Income tax and related interest and penalties would be recognized by the Fund as tax expense in the Statement of Operations if the tax positions were deemed not to meet the more-likely-than-not threshold. For the six months ended June 30, 2017, the Fund did not incur any income tax, interest, or penalties. As of June 30, 2017, the Adviser has reviewed all open tax years and concluded that there was no impact to

20

The Gabelli Global Utility & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

the Fund’s net assets or results of operations. The Fund’s federal and state tax returns for the prior three fiscal years remain open, subject to examination. On an ongoing basis, the Adviser will monitor the Fund’s tax positions to determine if adjustments to this conclusion are necessary.

3. Investment Advisory Agreement and Other Transactions. The Fund has entered into an investment advisory agreement (the “Advisory Agreement”) with the Adviser which provides that the Fund will pay the Adviser a fee, computed weekly and paid monthly, currently equal on an annual basis to 0.50% of the value of the Fund’s average weekly total assets. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund’s portfolio and oversees the administration of all aspects of the Fund’s business and affairs.

During the six months ended June 30, 2017, the Fund paid $3,152 in brokerage commissions on security trades to G.research, LLC, an affiliate of the Adviser.

During the six months ended June 30, 2017, the Fund received credits from a designated broker who agreed to pay certain Fund operating expenses. The amount of such expenses paid through this directed brokerage arrangement during this period was $940.

The cost of calculating the Fund’s NAV per share is a Fund expense pursuant to the Advisory Agreement. During the six months ended June 30, 2017, the Fund paid or accrued $22,500 to the Adviser in connection with the cost of computing the Fund’s NAV.

As per the approval of the Board, the Fund compensates officers of the Fund, who are employed by the Fund and are not employed by the Adviser (although the officers may receive incentive based variable compensation from affiliates of the Adviser). During the six months ended June 30, 2017, the Fund paid or accrued $60,792 in payroll expenses in the Statement of Operations.

The Fund pays each Trustee who is not considered an affiliated person an annual retainer of $3,000 plus $1,000 for each Board meeting attended. Each Trustee is reimbursed by the Fund for any out of pocket expenses incurred in attending meetings. All Board committee members receive $500 per meeting attended. The Audit Committee Chairman receives an annual fee of $3,000, the Nominating Committee Chairman receives an annual fee of $2,000, and the Lead Trustee receives an annual fee of $1,000. A Trustee may receive a single meeting fee, allocated among the participating funds, for participation in certain meetings held on behalf of multiple funds. Trustees who are directors or employees of the Adviser or an affiliated company receive no compensation or expense reimbursement from the Fund.

4. Portfolio Securities. Purchases and sales of securities during the six months ended June 30, 2017, other than short term securities and U.S. Government obligations, aggregated $4,034,174 and $3,458,752, respectively.

5. Capital. The Fund is authorized to issue an unlimited number of common shares of beneficial interest (par value $0.001). The Board has authorized the repurchase of its shares on the open market when the shares are trading at a discount of 10% or more (or such other percentage as the Board may determine from time to time) from the NAV of the shares. During the six months ended June 30, 2017 and the year ended December 31, 2016, the Fund did not repurchase and retire any shares in the open market.

In April 2013, the Fund distributed transferable rights for each of the 3,097,284 common shares outstanding. Three rights were required to purchase one additional common share and one newly issued Series A Cumulative Puttable and Callable Preferred Share (“Series A Preferred”) at the combined subscription price of $68.50 (consisting of $18.50 for each common share plus $50.00 for each Series A Preferred share). On June 19, 2013, the Fund issued 1,032,428 common shares and 1,032,428 Series A Preferred, receiving $70,286,465, after the deduction of offering expenses and solicitation fees of $369,721 and $65,132, respectively. The NAV per share of the Fund was reduced by approximately $1.00 as a result of the issuance of common shares below NAV.

The Fund’s Declaration of Trust, as amended, authorizes the issuance of an unlimited number of shares of $0.001 par value Preferred Shares. Preferred Shares are senior to the common shares and result in the financial leveraging of the common shares. Such leveraging tends to magnify both the risks and opportunities to common shareholders. Dividends on the Series A Preferred are cumulative and the liquidation value is $50 per share. The Fund is required by the 1940 Act and by the Fund’s Statement of Preferences to meet certain asset coverage tests with respect to the Preferred Shares. If the Fund fails to meet these requirements and does not correct such failure, the Fund may be required to redeem, in part or in full, the Series A Preferred Shares at the redemption price of $50 per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet these requirements. Additionally, failure to meet the foregoing asset coverage requirements could restrict the Fund’s ability to pay dividends to common shareholders and could lead to sales of portfolio securities at inopportune times. The income received on the Fund’s assets may vary in a manner unrelated to the fixed and variable rates, which could have either a beneficial or detrimental impact on net investment income and gains available to common shareholders.

The Series A Preferred had an annual dividend rate of 6.00% for the four dividend periods beginning in September 2013 ending on or prior to June 26, 2014, and 3.00% for the subsequent eight dividend periods ending on or prior to June 26, 2016. The Board increased the annual dividend rate to 3.8%, effective for the dividend periods after the dividend period ended June 26, 2016. The annual dividend rate of 3.8% was determined based on the terms of the Series A Preferred shares. During the year ended December 31, 2015, 6,346 Series A Preferred were put back to the Fund at $50 liquidation value plus accrued dividends. The Fund will redeem all or any part of the Series A Preferred that holders have properly submitted for redemption during the thirty day period prior to June 26, 2018 at the liquidation value plus any accumulated and unpaid dividends. The Series A Preferred is noncallable before June 19, 2018. At June 30, 2017, 1,026,082 Series A Preferred were outstanding and accrued dividends amounted to $27,077.

The holders of Preferred Shares generally are entitled to one vote per share held on each matter submitted to a vote of shareholders of the Fund and will vote together with holders of common shares as a single class. The holders of Preferred Shares voting together as a single class also have the right currently to elect two Trustees and under certain circumstances are entitled to elect a majority of the Board of Trustees. In addition, the affirmative vote of a majority of the votes entitled to be cast by holders of all outstanding shares of the Preferred Shares, voting as a single class, will be required to approve any plan of reorganization adversely affecting the Preferred Shares, and the approval of two-thirds of each class, voting separately, of the Fund’s outstanding voting stock must approve the conversion of the Fund from a closed-end to an open-end investment company. The approval of a majority (as defined in the 1940 Act) of the outstanding Preferred Shares and a

majority (as defined in the 1940 Act) of the Fund’s outstanding voting securities are required to approve certain other actions, including changes in the Fund’s investment objectives or fundamental investment policies.

6. Industry Concentration. Because the Fund primarily invests in common stocks and other securities of foreign and domestic companies in the utility industry, its portfolio may be subject to greater risk and market fluctuations than a portfolio of securities representing a broad range of investments.

7. Indemnifications. The Fund enters into contracts that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund’s existing contracts and expects the risk of loss to be remote.

8. Subsequent Events. Management has evaluated the impact on the Fund of all subsequent events occurring through the date the financial statements were issued and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements.

Shareholder Meeting – May 15, 2017 – Final Results

Board Consideration and Re-Approval of Investment Advisory Agreement (Unaudited)

At its meeting on May 17, 2017, the Board of Trustees (“Board”) of the Fund approved the continuation of the investment advisory agreement with the Adviser for the Fund on the basis of the recommendation by the trustees who are not “interested persons” of the Fund (the “Independent Board Members”). The following paragraphs summarize the material information and factors considered by the Independent Board Members as well as their conclusions relative to such factors.

Nature, Extent and Quality of Services. The Independent Board Members considered information regarding the portfolio manager, the depth of the analyst pool available to the Adviser and the portfolio manager, the scope of supervisory, administrative, shareholder, and other services supervised or provided by the Adviser and the absence of significant service problems reported to the Board. The Independent Board Members noted the experience, length of service, and reputation of the portfolio manager.

Investment Performance of the Fund and the Adviser. The Independent Board Members reviewed the performance of the Fund for the one, three, five, and ten year periods ended March 31, 2017 against a peer group of utility and infrastructure funds selected by the Adviser (the “Adviser Peer Group”) and against a peer group consisting of funds in the Fund’s Lipper category (the “Lipper Peer Group”). The Independent Board Members noted that the Fund’s performance for these periods generally ranked below the median and was the most favorable relative to the Adviser Peer Group and the Lipper Peer Group for the ten year period.

Profitability. The Independent Board Members reviewed summary data regarding the profitability of the Fund to the Adviser both with an administrative overhead charge and without such charge and found such profitability to be reasonable. The Independent Board Members also noted that a portion of the Fund’s portfolio transactions was executed by the Adviser’s affiliated broker, resulting in incremental profits to the broker.

Economies of Scale. The Independent Board Members discussed the major elements of the Adviser’s cost structure and the relationship of those elements to potential economies of scale. The Independent Board Members noted that the Fund was a closed-end fund and unlikely to realize any economies of scale potentially available through growth in the absence of additional offerings.

Sharing of Economies of Scale. The Independent Board Members noted that the investment advisory fee schedule for the Fund does not take into account any potential economies of scale.

Service and Cost Comparisons. The Independent Board Members compared the expense ratios of the investment advisory fee, other expenses, and total expenses of the Fund with similar expense ratios of the Adviser Peer Group and the Lipper Peer Group and noted that the advisory fee includes substantially all administrative services of the Fund as well as investment advisory services of the Adviser. The Independent Board Members noted that the Fund’s total expense ratio was above average and the Fund’s size was below average within the applicable peer groups. The Independent Board Members were presented with, but did not consider material to their decision, various information comparing the advisory fee with the fee for other types of accounts managed by the Adviser.

Conclusions. The Independent Board Members concluded that the Fund enjoyed highly experienced portfolio advisory services, good ancillary services, and a reasonable performance record within its conservative stance. The Independent Board Members also concluded that the Fund’s expense ratios were reasonable in light of the Fund’s size, and that, in part due to the Fund’s structure as a closed-end fund, economies of scale were not a significant factor in their thinking. The Independent Board Members did not view the potential profitability

25

Board Consideration and Re-Approval of Investment Advisory Agreement (Unaudited) (Continued)

of ancillary services as material to their decision. On the basis of the foregoing and without assigning particular weight to any single conclusion, the Independent Board Members determined to recommend continuation of the investment advisory agreement to the full Board.

Based on a consideration of all these factors in their totality, the Board Members, including all of the Independent Board Members, determined that the Fund’s advisory fee was fair and reasonable with respect to the quality of services provided and in light of the other factors described above that the Board Members deemed relevant. Accordingly, the Board Members determined to approve the continuation of the Fund’s Advisory Agreement. The Board Members based their decision on evaluations of all these factors as a whole and did not consider any one factor as all important or controlling.
