Commodity Futures Trading Commission Registration

.

 The Commodity Futures Trading Commission (“CFTC”) has adopted regulations that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. The investment adviser has claimed an exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of the Fund. Accordingly, neither the Fund nor the adviser with respect to the operation of the Fund is subject to CFTC regulation. Because of its management of other strategies, the Fund’s adviser is registered with the CFTC as a commodity pool operator. The adviser is also registered as a commodity trading advisor.

Managed Distribution Plan.

Pursuant to an exemptive order issued by the Securities and Exchange Commission (Order), the Fund is authorized to distribute long-term capital gains to shareholders more frequently than once per year. Pursuant to the Order, the Fund’s Board of Trustees approved a Managed Distribution Plan (MDP) pursuant to which the Fund makes monthly cash distributions to common shareholders, stated in terms of a fixed amount per common share.

The Fund currently distributes monthly cash distributions equal to $0.0579 per share in accordance with the MDP. You should not draw any conclusions about the Fund’s investment performance from the amount of these distributions or from the terms of the MDP. The MDP will be subject to regular periodic review by the Fund’s Board of Trustees and the Board may amend or terminate the MDP at any time without prior notice to Fund shareholders. However, at this time there are no reasonably foreseeable circumstances that might cause the termination of the MDP.

The Fund may distribute more than its net investment income and net realized capital gains and, therefore, a distribution may include a return of capital. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.” With each distribution, the Fund will issue a notice to shareholders and a press release containing information about the amount and sources of the distribution and other related information. The amounts and sources of distributions contained in the notice and press release are only estimates and are not provided for tax purposes. The amounts and sources of the Fund’s distributions for tax purposes will be reported to shareholders on Form 1099-DIV for each calendar year.

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

Management’s Discussion of Fund Performance

Economic and Market Conditions

For U.S. equity investors, the 12-month period ended December 31, 2023, was a roller-coaster ride, driven largely by shifting perceptions of whether the U.S. Federal Reserve (the Fed) could bring the world’s largest economy in for a soft landing, and changing expectations of how long interest rates might remain high.

As the period opened in January 2023, U.S. equities began a rally that lasted through July. The initial tailwind was ChatGPT, an artificial intelligence (AI) application that led investors to perceive AI might become the next big innovation to drive the information technology (IT) sector. As a result, IT -- one of the worst-performing sectors in 2022 -- became a standout sector in 2023. Earlier recession fears that had weighed on stock prices receded as more investors came to view the U.S. economy as doing surprisingly well.

But from August through October 2023, the bond market halted the stock market’s momentum. As investors feared the Fed might keep rates higher for longer than they had anticipated just a few months earlier, longer-term bond interest rates rose sharply. Given the potential for relatively attractive returns with lower risk than stocks, many investors shifted asset allocations from equities to bonds.

In the final two months of the period, however, U.S. equities made another U-turn, as investors again revised their expectations of what the Fed might do. Encouraged by cooling economic data and declining inflation, investors began to conclude the Fed was done raising interest rates -- and might begin lowering rates as early as March 2024.

In response, the U.S. stock market ended the period on a high note, with the S&P 500® Index, a broad measure of U.S. stocks; the blue-chip Dow Jones Industrial Average®; and the technology-laden Nasdaq Composite Index each rising more than 9% in November and more than 4% in December 2023. Unlike the equity rally during the first half of the period driven by a handful of large-cap technology-related stocks, the year-end rally extended across a wider range of market capitalizations, with the small-cap Russell 2000® Index keeping pace with its large-cap brethren in November, and significantly outperforming them in December.

For the period as a whole, U.S. equity performance was also strong. The S&P 500® Index returned 26.29%, the Dow Jones Industrial Average® returned 16.18%, the Nasdaq Composite Index returned 44.64%, and the Russell 2000® Index returned 16.93%.

Fund Performance

For the 12-month period ended December 31, 2023, Eaton Vance Risk-Managed Diversified Equity Income Fund (the Fund) returned 15.94% at net asset value of its common shares (NAV), underperforming its equity benchmark, the S&P 500® Index (the Index), which returned 26.29%; and underperforming its options benchmark, the Cboe S&P 500 95-110 Collar Index

SM

, which returned 18.25%.

The Fund’s collared-options strategy (the options strategy) was the largest single detractor from Fund performance versus the Index during the period. The options strategy may be beneficial during times of market weakness and higher volatility. But it may also detract from Fund performance relative to the Index during periods of market strength, since it seeks to buy downside protection at the expense of potential upside appreciation.

For much of the period, the Index moved sideways or higher as market volatility -- as measured by the Cboe Volatility Index®, or VIX -- declined. While the options strategy’s downside protection was helpful when market volatility spiked in mid-March and late September 2023, the overall market strength during the period created net losses in the options strategy.

The Fund’s common stock portfolio outperformed the Index, contributing to returns relative to the Index during the period. On an individual stock basis, the largest contributor to performance versus the Index was an overweight position in Meta Platforms, Inc. (Meta), the social media giant behind Facebook, Instagram, and Messenger. Meta’s stock price more than doubled during the period as advertising revenues rebounded on improved ad targeting, while profit margins exceeded expectations due to more rational spending on longer-term initiatives.

On a sector basis, stock selections and an overweight position in the communication services sector, along with stock selections in the health care and industrials sectors, contributed to Fund performance versus the Index during the period.

In contrast, the largest individual stock detractor from performance relative to the Index was an overweight position in Humana, Inc. (Humana), a managed health care company that focuses on the Medicare Advantage population. Humana’s share price declined over concerns about a rumored merger with Cigna Group that raised doubts about Humana’s future growth prospects; rising costs for treating Medicare patients; and the perceived end of the U.S. Federal Reserve’s program of interest rate hikes, which had been a tailwind for managed health care companies.

Past performance is no guarantee of future results. Returns are historical and are calculated net of management fees and other expenses by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributions reinvested in accordance with the Fund’s Dividend Reinvestment Plan. Furthermore, returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares. Performance at market price will differ from performance at NAV due to variations in the Fund’s market price versus NAV, which may reflect factors such as fluctuations in supply and demand for Fund shares, changes in Fund distributions, shifting market expectations for the Fund’s future returns and distribution rates, and other considerations affecting the trading prices of closed-end funds. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance for periods less than or equal to one year is cumulative. Performance is for the stated time period only; due to market volatility, current Fund performance may be lower or higher than the quoted return.

On a sector basis, stock selections in the consumer discretionary sector, stock selections and an underweight position in the information technology sector, and stock selections and an overweight position in the consumer staples sector detracted from Fund performance versus the Index during the period.

Fund Distributions

Pursuant to an exemptive order issued by the Securities and Exchange Commission (the Order), the Fund is authorized to distribute long-term capital gains to shareholders more frequently than once per year. Pursuant to the Order, the Fund’s Board of Trustees approved a Managed Distribution Plan (MDP) pursuant to which the Fund makes monthly cash distributions to common shareholders. The Fund’s MDP had no effect on the Fund’s investment strategy during the most recent fiscal year and is not expected to have an effect in future periods, but distributions in excess of Fund returns will cause its per share NAV to erode. Investors should not draw any conclusions about the Fund’s investment performance from the amount of its distribution or from the terms of its MDP.

For the period from January 1, 2023 to December 31, 2023, the Fund made monthly distributions of $0.0579 per share. The Fund’s distributions may be comprised of amounts characterized for federal income tax purposes as qualified and non-qualified ordinary dividends, capital gains and non-dividend distributions, also known as return of capital distributions. The federal income tax character of distributions is determined after the end of the calendar year and reported to shareholders on the Internal Revenue Service’s form 1099-DIV. For additional information, see Note 2 in the Notes to Financial Statements herein.

The Fund's Investment Objectives, Principal Strategies and Principal Risks

‡

Investment Objectives

.

 

The Fund’s primary investment objective is to provide current income and gains, with a secondary objective of capital appreciation. In pursuing its investment objectives, the Fund evaluates returns on an after-tax basis, seeking to minimize and defer shareholder federal income taxes.

Principal Strategies. 

Under normal market conditions, the Fund’s investment program consists primarily of owning a diversified portfolio of common stocks and employing a variety of options strategies. The Fund seeks to earn high levels of tax-advantaged income and gains by (1) investing in stocks that pay dividends that qualify for favorable federal income tax treatment, (2) writing (selling) put options on individual stocks deemed attractive for purchase, and/or (3) writing (selling) stock index call options with respect to a portion of its common stock portfolio value. To reduce the Fund’s risk of loss due to a decline in the value of the general equity market, the Fund intends to purchase index put options with respect to a substantial portion of the value of its common stock holdings and stocks subject to written put options.

Under normal market conditions, the Fund invests at least 80% of its total assets in a combination of (1) dividend-paying common stocks, (2) common stocks the value of which is subject to written put options on individual stocks, and (3) common stocks the value of which is subject to written index call options. In addition, under normal market conditions, the Fund purchases index put options with respect to at least 80% of the value of its investments in common stocks. The Fund may consider investments in stocks that pay dividends that qualify for federal income taxation at rates applicable to long-term capital gains. The Fund generally intends to buy put options and write call options on one or more broad-based stock indices that the investment adviser believes collectively approximate the characteristics of its common stock portfolio (or that portion of its portfolio against which options are purchased and written). The Fund intends to buy put options and write call options primarily on the S&P 500, and may also buy put options and write call options on other domestic and foreign stock indices. The Fund’s current options strategy consists of purchasing out-of-the-money S&P 500 Index put options and selling out-of-the-money S&P 500 Index call options on all or substantially all of the value of the Fund’s common stock portfolio. Purchasing index put options provides protection against loss of principal value during periods of market weakness and selling index call options generates premium income. The Fund generally intends to purchase short-dated (generally 28-day) index put options and sell index call options of the same term, staggering roll dates across the options portfolio. The indices on which the Fund buys put options and writes call options may vary as a result of changes in the availability and liquidity of various listed index options, changes in stock portfolio holdings, the Adviser’s evaluation of equity market conditions and other factors. The buying of index put options will reduce the Fund’s cash available for distribution from other sources, including from selling put options on individual stocks and index call options.

The Fund invests primarily in common stocks of United States issuers. The Fund may invest up to 40% of its total assets in securities of foreign issuers, including securities evidenced by American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”). The Fund may invest up to 5% of its total assets in securities of emerging market issuers. The Fund expects that its assets will normally be invested across a broad range of industries and market sectors. The Fund may not invest 25% or more of its total assets in the securities of issuers in any single industry. Eaton Vance generally considers mid-capitalization companies to be those companies having market capitalizations within the range of capitalizations for the S&P MidCap 400® Index (the “S&P MidCap 400®”). As of December 31, 2023, the median market capitalization of companies in the S&P MidCap 400® was approximately $6.3 billion. Market capitalizations of companies within the S&P MidCap 400® are subject to change.

During unusual market circumstances, the Fund may invest up to 100% of assets in cash or cash equivalents temporarily, which may be inconsistent with the Fund’s investment objective and other policies.

Principal Risks

Market Discount Risk.

As with any security, the market value of the common shares may increase or decrease from the amount initially paid for the common shares. The Fund’s common shares have traded both at a premium and at a discount relative to NAV. The shares of closed-end management investment companies frequently trade at a discount from their NAV. This is a risk separate and distinct from the risk that the Fund’s NAV may decrease.

Investment and Market Risk.

An investment in common shares is subject to investment risk, including the possible loss of the entire principal amount invested. An investment in common shares represents an indirect investment in the securities owned by the Fund, which are generally traded on a securities exchange or in the over-the-counter markets. The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. Because the Fund may sell stock index call options on a portion of its common stock portfolio value, the Fund’s appreciation potential from equity market performance may be more limited than if the Fund did not engage in selling stock index call options. Because the Fund may sell put options on individual stocks, the Fund’s exposure to loss from a decline in the value of such stocks may increase. To the extent that the individual stocks held by the Fund and/or the stocks subject to written put options decrease in value more than the index or indices on which the Fund has purchased put options, the strategy of purchasing index put options will provide only limited protection with respect to the value of the Fund’s assets and may result in worse performance for the Fund than if it did not buy index put options. The common shares at any point in time may be worth less than the original investment, even after taking into account any reinvestment of distributions.

The value of investments held by the Fund may increase or decrease in response to social, economic, political, financial, public health crises or other disruptive events (whether real, expected or perceived) in the U.S. and global markets and include events such as war, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest. These events may negatively impact broad segments of businesses and populations and may exacerbate pre-existing risks to the Fund. The frequency and magnitude of resulting changes in the value of the Fund’s investments cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in reaction to changing

market conditions. Monetary and/or fiscal actions taken by U.S. or foreign governments to stimulate or stabilize the global economy may not be effective and could lead to high market volatility. No active trading market may exist for certain investments held by the Fund, which may impair the ability of the Fund to sell or to realize the current valuation of such investments in the event of the need to liquidate such assets.

Issuer Risk.

The value of securities held by the Fund may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.

Equity Securities Risk.

The value of equity securities and related instruments may decline in response to adverse changes in the economy or the economic outlook; deterioration in investor sentiment; interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer and sector-specific considerations; unexpected trading activity among retail investors; or other factors. Market conditions may affect certain types of stocks to a greater extent than other types of stocks. If the stock market declines in value, the value of the Fund’s equity securities will also likely decline. Although prices can rebound, there is no assurance that values will return to previous levels.

Limitations on Equity Market Risk Management Strategy.

To manage the risk of a decline in the value of the general equity market, the Fund purchases index put options on a substantial portion of the value of its common stock holdings. As the purchaser of an index put option, the Fund would pay to the writer (seller) of the option cash (the premium), and the Fund has the right to receive from the seller the amount by which the cash value of the index is below the exercise price as of the valuation date of the option. If the Fund exercises the index put option, the seller would pay the Fund the difference between the exercise price and the value of the index. There are a number of limitations on the extent to which common shareholders of the Fund may benefit from this risk management strategy.

First, holding an index put option generally provides a hedge against a decline in the applicable index to levels below the exercise price on the option. A decline in the index to a level above the exercise price would result in the option expiring worthless if held until expiration. Generally, the Fund intends to buy index put options that are “out-of-the-money” (i.e., the exercise price generally is below the current level of the applicable index when the option is purchased). Options that are more “out-of-the-money” provide the Fund with less protection against a decline in the applicable index.

Second, there is a risk that the value of the stock indices subject to purchased put options will not correlate with the value of the Fund’s portfolio holdings. The Fund intends to buy put options on one or more broad-based stock indices that the Adviser believes collectively approximate the characteristics of the Fund’s common stock portfolio (or that portion of its portfolio against which put options are acquired). The Fund will not, however, hold stocks that fully replicate the indices on which it buys put options. Due to tax considerations, the Fund intends to generally limit the overlap between its stock holdings (and any subset thereof) and each index on which it has outstanding options positions to less than 70% on an ongoing basis. The Fund’s stock holdings will normally include stocks not included in the indices on which it buys put options. Accordingly, the value of the indices may remain flat or increase in value at times when the Fund’s portfolio holdings are decreasing in value. Similarly, the indices may decrease in value but to a lesser extent than the Fund’s portfolio holdings. In such cases, the index put options would provide only a limited hedge against a decline in the value of the Fund’s portfolio holdings and may result in worse performance for the Fund than if it did not buy index put options. The use of index put options cannot serve as a complete hedge since the price movement of the indices underlying the options will not necessarily follow the price movements of the Fund’s portfolio holdings. Correlation risks are also presented in connection with the Fund’s selling of put options on individual stocks and purchasing index puts to hedge the associated increase in market risk. Purchasing index put options with respect to single stock put options written does not protect the Fund against the risk that the stocks against which put options are written decrease in value relative to the index on which put options are purchased and may result in greater costs and losses to the Fund than a strategy that does not involve such hedging.

Third, the Fund may in certain circumstances hold stock index put options with respect to only a portion of the value of its common stock holdings, subject to the condition that, under normal market conditions, the Fund will hold index put options with respect to at least 80% of the value of its investments in common stocks. The portion of the Fund’s portfolio value against which index put options are not acquired will not benefit from this risk management strategy.

Index put options can be highly volatile instruments. This may cause options positions held to react to market changes differently than the Fund’s portfolio securities and stocks subject to written put options. A put option acquired by the Fund and not sold prior to expiration will expire worthless if the price of the index at expiration exceeds the exercise price of the option, thereby causing the Fund to lose its entire investment in the option. If restrictions on exercise were imposed, the Fund might be unable to exercise an option it had purchased. If the Fund were unable to close out an option that it had purchased, it would have to exercise the option in order to realize any profit or the option may expire worthless.

Option Strategy Risk.

The Fund’s option strategy seeks to take advantage of, and its effectiveness is dependent on, a general excess of option price implied volatilities for the S&P 500 over realized index volatilities. This market observation is often attributed to an excess of natural buyers over natural sellers of S&P 500 index options. There can be no assurance that this imbalance will apply in the future over specific periods or generally. It is possible that the imbalance could decrease or be eliminated by actions of investors, including the Fund, that employ strategies seeking to take advantage of the imbalance, which could have an adverse effect on the Fund’s ability to achieve its investment objective.

Risk of Selling Index Call Options.

The purchaser of an index call option has the right to any appreciation in the value of the index over the exercise price of the call option as of the valuation date of the option. Because their exercise is settled in cash, sellers of index call options such as the Fund cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund intends to mitigate the risks of its options activities by holding a diversified portfolio of stocks that the Fund’s investment adviser believes collectively approximate the characteristics of the

indices on which options are written. The Fund will not, however, hold stocks that fully replicate the indices on which it writes call options. Due to tax considerations, the Fund intends to limit the overlap between its stock holdings (and any subset thereof) and each index on which it has outstanding options positions to less than 70% on an ongoing basis. The Fund’s stock holdings will normally include stocks not included in the indices on which it writes call options. Consequently, the Fund bears the risk that the performance of its stock portfolio will vary from the performance of the indices on which it writes call options. As the writer of index call options, the Fund will forgo, during the option’s life, the opportunity to profit from increases in the value of the applicable index above the sum of the option premium received and the exercise price of the call option, but retains the risk of loss, minus the option premium received, should the value of the applicable index decline. When a call option is exercised, the Fund will be required to deliver an amount of cash determined by the excess of the value of the applicable index at contract termination over the exercise price of the option. Thus, the exercise of index call options sold by the Fund may require the Fund to sell portfolio securities to generate cash at inopportune times or for unattractive prices. The trading price of options may be adversely affected if the market for such options becomes less liquid or smaller. The Fund may close out a call option by buying the option instead of letting it expire or be exercised. There can be no assurance that a liquid market will exist when the Fund seeks to close out a call option position by buying the option.

Risks of Selling Put Options on Individual Stocks.

The Fund may write put options on individual stocks that the Adviser believes are attractive for purchase at prices at or above the exercise price of the put options written. The purchaser of a put option assumes the right to sell (put) the stock to the seller of the option at a specified price (the exercise price) on or before the expiration date of the option. If the value of the stock on the option expiration date is at or below the exercise price of the option, the Fund may be obligated to purchase the stock at the exercise price. In the event of a substantial depreciation in the value of the underlying stock, the Fund may incur a substantial loss.

Options Risks Generally.

A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well-conceived and well-executed options program may be adversely affected by market behavior or unexpected events. Successful options strategies may require the anticipation of future movements in securities prices, interest rates and other economic factors. No assurances can be given that the Adviser’s judgments in this respect will be correct.

The trading price of options may be adversely affected if the market for such options becomes less liquid or smaller. The Fund may close out a written option position by buying the option instead of letting it expire or be exercised. Similarly, the Fund may close out a purchased option position by selling the option instead of holding until exercise. There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position by buying or selling the option. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or the Options Clearing Corporation (the “OCC”) may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled to discontinue the trading of options (or a particular class or series of options) at some future date. If trading were discontinued, the secondary market on that exchange (or in that class or series of options) would cease to exist. However, outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

The Fund’s options positions will be marked to market daily. The hours of trading for options may not conform to the hours during which common stocks held by the Fund are traded. To the extent that the options markets close before the markets for securities, significant price and rate movements can take place in the securities markets that would not be reflected concurrently in the options markets. The value of index options is affected by changes in the value and dividend rates of the securities represented in the underlying index, changes in interest rates, changes in the actual or perceived volatility of the associated index and the remaining time to the options’ expiration, as well as trading conditions in the options market. Similarly, the value of single stock options is affected by changes in the value and dividend rate of the underlying stock, changes in interest rates, changes in the actual or perceived volatility of the associated stock and the remaining time to the options’ expiration, as well as options market trading conditions.

The Fund’s options transactions will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities on which such options are traded. These limitations govern the maximum number of options in each class which may be written or purchased by a single investor or group of investors acting in concert, regardless of whether the options are written or purchased on the same or different exchanges, boards of trade or other trading facilities or are held or written in one or more accounts or through one or more brokers. Thus, the number of options which the Fund may write or purchase may be affected by options written or purchased by other investment advisory clients of the Adviser or. An exchange, board of trade or other trading facility may order the liquidation of positions found to be in excess of these limits, and may impose certain other sanctions. The Fund will not write “naked” or uncovered call options.

To the extent that the Fund buys or writes options on indices based upon foreign stocks, the Fund generally intends to buy or sell options on broad-based foreign country and/or regional stock indices that are listed for trading in the United States or which otherwise qualify as “section 1256 contracts” under the Code. Options on foreign indices that are listed for trading in the United States or which otherwise qualify as “section 1256 contracts” under the Code may trade in substantially lower volumes and with substantially wider bid-ask spreads than other options contracts on the same or similar indices that trade on other markets outside the United States. To implement its options program most effectively, the Fund may buy or sell index options that do not qualify as “section 1256 contracts” under the Code. Gain or loss on index options not qualifying as “section 1256 contracts” under the Code would be realized upon disposition, lapse or settlement of the positions and, generally, would be treated as short-term gain or loss.

Item 4. Principal Accountant Fees and Services

a) –(d)

The following table presents the aggregate fees billed to the registrant for the registrant’s fiscal years ended December 31, 2022 and December 31, 2023 by the registrant’s principal accountant, Deloitte & Touche LLP (“D&T”), for professional services rendered for the audit of the registrant’s annual financial statements and fees billed for other services rendered by D&T during such periods.

(e)(1) The registrant’s audit committee has adopted policies and procedures relating to the pre-approval of services provided by the registrant’s principal accountant (the “Pre-Approval Policies”). The Pre-Approval Policies establish a framework intended to assist the audit committee in the proper discharge of its pre-approval responsibilities. As a general matter, the Pre-Approval Policies (i) specify certain types of audit, audit-related, tax, and other services determined to be pre-approved by the audit committee; and (ii) delineate specific procedures governing the mechanics of the pre-approval process, including the approval and monitoring of audit and non-audit service fees. Unless a service is specifically pre-approved under the Pre-Approval Policies, it must be separately pre-approved by the audit committee.

The Pre-Approval Policies and the types of audit and non-audit services pre-approved therein must be reviewed and ratified by the registrant’s audit committee at least annually. The registrant’s audit committee maintains full responsibility for the appointment, compensation, and oversight of the work of the registrant’s principal accountant.

(h) The registrant’s audit committee has considered whether the provision by the registrant’s principal accountant of non-audit services to the registrant’s investment adviser and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant that were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X is compatible with maintaining the principal accountant’s independence.

(i) Not applicable.

(j) Not applicable.

Please see schedule of investments contained in the Report to Stockholders included under Item 1 of this Form N-CSR.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

The Board of the Fund has adopted a proxy voting policy and procedure (the “Fund Policy”), pursuant to which the trustees have delegated proxy voting responsibility to the Fund’s investment adviser and adopted the investment adviser’s proxy voting policies and procedures (the “Policies”) which are described below. The trustees will review the Policies annually. In the event that a conflict of interest arises between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund, the investment adviser will generally refrain from voting the proxies related to the companies giving rise to such conflict until it consults with the Board, or any committee, sub-committee or group of independent trustees identified by the Board, which will instruct the investment adviser on the appropriate course of action. If the Board Members are unable to meet and the failure to vote a proxy would have a material adverse impact on the Fund, the investment adviser may vote such proxy, provided that it discloses the existence of the material conflict to the Chairperson of the Fund’s Board as soon as practicable and to the Board at its next meeting.

The Policies are designed to promote accountability of a company’s management to its shareholders and to align the interests of management with those shareholders. An independent proxy voting service (“Agent”), currently Institutional Shareholder Services, Inc., has been retained to assist in the voting of proxies through the provision of vote analysis, implementation and recordkeeping and disclosure services. The investment adviser will generally vote proxies through the Agent. The Agent is required to vote all proxies in accordance with customized proxy voting guidelines (the “Guidelines”) and/or refer them back to the investment adviser pursuant to the Policies.

The Agent is required to establish and maintain adequate internal controls and policies in connection with the provision of proxy voting services, including methods to reasonably ensure that its analysis and recommendations are not influenced by a conflict of interest. The Guidelines include voting guidelines for matters relating to, among other things, the election of directors, approval of independent auditors, executive compensation, corporate structure and anti-takeover defenses. The investment adviser may cause the Fund to abstain from voting from time to time where it determines that the costs associated with voting a proxy outweigh the benefits derived from exercising the right to vote or it is unable to access or access timely ballots or other proxy information, among other stated reasons. The Agent will refer Fund proxies to the investment adviser for instructions under circumstances where, among others: (1) the application of the Guidelines is unclear; (2) a particular proxy question is not covered by the Guidelines; or (3) the Guidelines require input from the investment adviser. When a proxy voting issue has been referred to the investment adviser, the analyst (or portfolio manager if applicable) covering the company subject to the proxy proposal determines the final vote (or decision not to vote) and the investment adviser’s Proxy Administrator (described below) instructs the Agent to vote accordingly for securities held by the Fund. Where more than one analyst covers a particular company and the recommendations of such analysts voting a proposal conflict, the investment adviser’s Global Proxy Group (described below) will review such recommendations and any other available information related to the proposal and determine the manner in which it should be voted, which may result in different recommendations for the Fund that may differ from other clients of the investment adviser.

The investment adviser has appointed a Proxy Administrator to assist in the coordination of the voting of client proxies (including the Fund’s) in accordance with the Guidelines and the Policies. The investment adviser and its affiliates have also established a Global Proxy Group. The Global Proxy Group develops the investment adviser’s positions on all major corporate issues, creates the Guidelines and oversees the proxy voting process. The Proxy Administrator maintains a record of all proxy questions that have been referred by the Agent, all applicable recommendations, analysis and research received and any resolution of the matter. Before instructing the Agent to vote contrary to the Guidelines or the recommendation of the Agent, the Proxy Administrator will provide the Global Proxy Group with the Agent’s recommendation for the proposal along with any other relevant materials, including the basis for the analyst’s recommendation. The Proxy Administrator will then instruct the Agent to vote the proxy in the manner determined by the Global Proxy Group. A similar process will be followed if the Agent has a conflict of interest with respect to a proxy. The investment adviser will report to the Fund’s Board any votes cast contrary to the Guidelines or Agent recommendations, as applicable, no less than annually.

The investment adviser’s Global Proxy Group is responsible for monitoring and resolving possible material conflicts with respect to proxy voting. Because the Guidelines are predetermined and designed to be in the best interests of shareholders, application of the Guidelines to vote client proxies should, in most cases, adequately address any possible conflict of interest. The investment adviser will monitor situations that may result in a conflict of interest between any of its clients and the investment adviser or any of its affiliates by maintaining a list of significant existing and prospective corporate clients. The Proxy Administrator will compare such list with the names of companies of which he or she has been referred a proxy statement (the “Proxy Companies”). If a company on the list is also a Proxy Company, the Proxy Administrator will report that fact to the Global

Proxy Group. If the Proxy Administrator intends to instruct the Agent to vote in a manner inconsistent with the Guidelines, the Global Proxy Group will first determine, in consultation with legal counsel if necessary, whether a material conflict exists. If it is determined that a material conflict exists, the investment adviser will seek instruction on how the proxy should be voted from the Fund’s Board, or any committee or subcommittee identified by the Board. If a matter is referred to the Global Proxy Group, the decision made and basis for the decision will be documented by the Proxy Administrator and/or Global Proxy Group.

Information on how the Fund voted proxies relating to portfolio securities during the most recent 12 month period ended June 30 is available (1) without charge, upon request, by calling 1-800-262-1122, and (2) on the Securities and Exchange Commission’s website at http://www.sec.gov.

Item 8. Portfolio Managers of Closed-End Management Investment Companies

Eaton Vance Management (“EVM” or “Eaton Vance”) is the investment adviser of the Fund. Charles B. Gaffney and Douglas R. Rogers, CFA, CMT are responsible for the overall and day-to-day management of the Fund’s investments. Messrs. Gaffney and Rogers are Vice Presidents of Eaton Vance, have managed other Eaton Vance portfolios for more than five years, and have been portfolio managers of the Fund since May 2023.

The following table shows, as of the Fund’s most recent fiscal year end, the number of accounts each portfolio manager managed in each of the listed categories and the total assets (in millions of dollars) in the accounts managed within each category. The table also shows the number of accounts with respect to which the advisory fee is based on the performance of the account, if any, and the total assets (in millions of dollars) in those accounts.

The following table shows the dollar range of Fund shares beneficially owned by the portfolio manager as of the Fund’s most recent fiscal year end.

Potential for Conflicts of Interest. It is possible that conflicts of interest may arise in connection with a portfolio manager’s management of the Fund’s investments on the one hand and the investments of other accounts for which a portfolio manager is responsible on the other. For example, a portfolio manager may have conflicts of interest in allocating management time, resources and investment opportunities among the Fund and other accounts he advises. In addition, due to differences in the investment strategies or restrictions between the Fund and the other accounts, the portfolio manager may take action with respect to another account that differs from the action taken with respect to the Fund. In some cases, another account managed by a portfolio manager may compensate the investment adviser based on the performance of the securities held by that account. The existence of such a performance based fee may create additional conflicts of interest for the portfolio manager in the allocation of management time, resources and investment opportunities. Whenever conflicts of interest arise, the portfolio manager will endeavor to exercise his discretion in a manner that he believes is equitable to all interested persons. EVM has adopted several policies and procedures designed to address these potential conflicts including a code of ethics and policies that govern the investment adviser’s trading practices, including among other things the aggregation and allocation of trades among clients, brokerage allocations, cross trades and best execution.

Compensation Structure for EVM

The compensation structure of Eaton Vance and its affiliates that are investment advisers (for purposes of this section “Eaton Vance”) is based on a total reward system of base salary and incentive compensation, which is paid either in the form of cash bonus, or for employees meeting the specified deferred compensation eligibility threshold, partially as a cash bonus and partially as mandatory deferred compensation. Deferred compensation granted to Eaton Vance employees is generally granted as a mix of deferred cash awards under the Investment Management Alignment Plan (IMAP) and equity-based awards in the form of stock units. The portion of incentive compensation granted in the form of a deferred compensation award and the terms of such awards are determined annually by the Compensation, Management Development and Succession Committee of the Board of Directors of Eaton Vance’s parent company, Morgan Stanley.

Base salary compensation. Generally, portfolio managers and research analysts receive base salary compensation based on the level of their position with the Adviser.

Incentive compensation. In addition to base compensation, portfolio managers and research analysts may receive discretionary year-end compensation. Incentive compensation may include:

Eaton Vance compensates employees based on principles of pay-for-performance, market competitiveness and risk management. Eligibility for, and the amount of any, discretionary compensation is subject to a multi-dimensional process. Specifically, consideration is given to one or more of the following factors, which can vary by portfolio management team and circumstances:

Further, the firm’s Global Incentive Compensation Discretion Policy requires compensation managers to consider only legitimate, business related factors when exercising discretion in determining variable incentive compensation, including adherence to Morgan Stanley’s core values, conduct, disciplinary actions in the current performance year, risk management and risk outcomes.
