Semiannual Report

March 31, 2021

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 $0.0898 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.

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. 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. For performance as of the most recent month-end, please refer to eatonvance.com.

² The shares of the Fund often trade at a discount or premium to their net asset value. The discount or premium may vary over time and may be higher or lower than what is quoted in this report. For up-to-date premium/discount information, please refer to https://funds.eatonvance.com/closed-end-fund-prices.php.

³ The Distribution Rate is based on the Fund’s last regular distribution per share in the period (annualized) divided by the Fund’s NAV or market price at the end of the period. 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 nondividend distributions, also known as return of capital. As of 03/31/2021, distributions included estimates of return of capital. For additional information about nondividend distributions, please refer to Eaton Vance Closed-End Fund Distribution Notices (19a) posted on our website, eatonvance.com. The Fund will determine the federal income tax character of distributions paid to a shareholder after the end of the calendar year. This is reported on the IRS form 1099-DIV and provided to the shareholder shortly after each year-end. For information about the tax character of distributions made in prior calendar years, please refer to Performance-Tax Character of Distributions on the Fund’s webpage available at eatonvance.com. In recent years, a significant portion of the Fund’s distributions has been characterized as a return of capital. The Fund’s distributions are determined by the investment adviser based on its current assessment of the Fund’s long-term return potential. Fund distributions may be affected by numerous factors including changes in Fund performance, the cost of financing for leverage, portfolio holdings, realized and projected returns, and other factors. As portfolio and market conditions change, the rate of distributions paid by the Fund could change.

Notes to Financial Statements (Unaudited)

1  Significant Accounting Policies

Eaton Vance Enhanced Equity Income Fund (the Fund) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, closed-end management investment company. The Fund’s primary investment objective is to provide current income, with a secondary objective of capital appreciation.

The following is a summary of significant accounting policies of the Fund. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946.

A  Investment Valuation — The following methodologies are used to determine the market value or fair value of investments.

Equity Securities. Equity securities listed on a U.S. securities exchange generally are valued at the last sale or closing price on the day of valuation or, if no sales took place on such date, at the mean between the closing bid and ask prices on the exchange where such securities are principally traded. Equity securities listed on the NASDAQ Global or Global Select Market generally are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and ask prices.

Derivatives. U.S. exchange-traded options are valued at the mean between the bid and ask prices at valuation time as reported by the Options Price Reporting Authority. Non U.S. exchange-traded options and over-the-counter options are valued by a third party pricing service using techniques that consider factors including the value of the underlying instrument, the volatility of the underlying instrument and the period of time until option expiration.

Foreign Securities and Currencies. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rate quotations supplied by a third party pricing service. The pricing service uses a proprietary model to determine the exchange rate. Inputs to the model include reported trades and implied bid/ask spreads. The daily valuation of exchange-traded foreign securities generally is determined as of the close of trading on the principal exchange on which such securities trade. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the New York Stock Exchange. When valuing foreign equity securities that meet certain criteria, the Fund’s Trustees have approved the use of a fair value service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that have a strong correlation to the fair-valued securities.

Affiliated Fund. The Fund may invest in Eaton Vance Cash Reserves Fund, LLC (Cash Reserves Fund), an affiliated investment company managed by Eaton Vance Management (EVM). While Cash Reserves Fund is not a registered money market mutual fund, it conducts all of its investment activities in accordance with the requirements of Rule 2a-7 under the 1940 Act. Investments in Cash Reserves Fund are valued at the closing net asset value per unit on the valuation day. Cash Reserves Fund generally values its investment securities based on available market quotations provided by a third party pricing service.

Fair Valuation. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued at fair value using methods determined in good faith by or at the direction of the Trustees of the Fund in a manner that most fairly reflects the security’s “fair value”, which is the amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies or entities, quotations or relevant information obtained from broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial statements, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B  Investment Transactions — Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost.

C  Income — Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. However, if the ex-dividend date has passed, certain dividends from foreign securities are recorded as the Fund is informed of the ex-dividend date. Withholding taxes on foreign dividends and capital gains have been provided for in accordance with the Fund’s understanding of the applicable countries’ tax rules and rates.

D  Federal Taxes — The Fund’s policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year substantially all of its net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary.

As of March 31, 2021, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Fund files a U.S. federal income tax return annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

E  Foreign Currency Translation — Investment valuations, other assets, and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investment securities and income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates in effect on the respective dates of such transactions. Recognized gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net

12

Enhanced Equity Income Fund

March 31, 2021

Notes to Financial Statements (Unaudited) — continued

realized gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

F  Use of Estimates — The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates.

G  Indemnifications — Under the Fund’s organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Fund. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Fund) could be deemed to have personal liability for the obligations of the Fund. However, the Fund’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and the By-laws provide that the Fund shall assume, upon request by the shareholder, the defense on behalf of any Fund shareholders. Moreover, the By-laws also provide for indemnification out of Fund property of any shareholder held personally liable solely by reason of being or having been a shareholder for all loss or expense arising from such liability. Additionally, in the normal course of business, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

H  Written Options — Upon the writing of a call or a put option, the premium received by the Fund is included in the Statement of Assets and Liabilities as a liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written, in accordance with the Fund’s policies on investment valuations discussed above. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. When an index option is exercised, the Fund is required to deliver an amount of cash determined by the excess of the exercise price of the option over the value of the index (in the case of a put) or the excess of the value of the index over the exercise price of the option (in the case of a call) at contract termination. If a put option on a security is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as a writer of an option, may have no control over whether the underlying securities or other assets may be sold (call) or purchased (put) and, as a result, bears the market risk of an unfavorable change in the price of the securities or other assets underlying the written option. The Fund may also bear the risk of not being able to enter into a closing transaction if a liquid secondary market does not exist.

I  Interim Financial Statements — The interim financial statements relating to March 31, 2021 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2  Distributions to Shareholders and Income Tax Information

Subject to its Managed Distribution Plan, the Fund makes monthly distributions from its cash available for distribution, which consists of the Fund’s dividends and interest income after payment of Fund expenses, net option premiums and net realized and unrealized gains on stock investments. The Fund intends to distribute all or substantially all of its net realized capital gains. Distributions are recorded on the ex-dividend date. Distributions to shareholders are determined in accordance with income tax regulations, which may differ from U.S. GAAP. As required by U.S. GAAP, only distributions in excess of tax basis earnings and profits are reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income. Distributions in any year may include a substantial return of capital component. For the six months ended March 31, 2021, the amount of distributions estimated to be a tax return of capital was approximately $11,318,000. The final determination of tax characteristics of the Fund’s distributions will occur at the end of the year, at which time it will be reported to the shareholders.

At September 30, 2020, the Fund, for federal income tax purposes, had deferred capital losses of $20,875,028 which would reduce its taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus would reduce the amount of distributions to shareholders, which would otherwise be necessary to relieve the Fund of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Fund’s next taxable year and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at September 30, 2020, $20,875,028 are short-term.

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Fund at March 31, 2021, as determined on a federal income tax basis, were as follows:

Aggregate cost	$	393,079,541
Gross unrealized appreciation	$	298,876,464
Gross unrealized depreciation		(3,030,784	)
Net unrealized appreciation	$	295,845,680

3  Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by EVM as compensation for investment advisory services rendered to the Fund. On March 1, 2021, Morgan Stanley acquired Eaton Vance Corp. (the “Transaction”) and EVM became an indirect, wholly-owned subsidiary of Morgan Stanley. In connection with the Transaction, the Fund entered into a new investment advisory agreement (the “New Agreement”) with EVM, which took effect on March 1, 2021. Pursuant to the New Agreement (and the Fund’s investment advisory agreement with EVM in effect prior to March 1, 2021), the fee is computed at an annual rate of 1.00% of the Fund’s average daily gross assets and is payable monthly. Gross assets as referred to herein represent net assets plus obligations attributable to investment leverage, if any. For the six months ended March 31, 2021, the Fund’s investment adviser fee amounted to $3,274,645. The Fund invests its cash in Cash Reserves Fund. EVM does not currently receive a fee for advisory services provided to Cash Reserves Fund. EVM also serves as administrator of the Fund, but receives no compensation.

Trustees and officers of the Fund who are members of EVM’s organization receive remuneration for their services to the Fund out of the investment adviser fee. Trustees of the Fund who are not affiliated with EVM may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended March 31, 2021, no significant amounts have been deferred. Certain officers and Trustees of the Fund are officers of EVM.

4  Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, aggregated $131,572,277 and $151,480,628, respectively, for the six months ended March 31, 2021.

5  Common Shares of Beneficial Interest and Shelf Offering

The Fund may issue common shares pursuant to its dividend reinvestment plan. There were no common shares issued by the Fund for the six months ended March 31, 2021. Common shares issued by the Fund pursuant to its dividend reinvestment plan for the year ended September 30, 2020 were 29,982.

Pursuant to a registration statement filed with and declared effective on April 11, 2019 by the SEC, the Fund is authorized to issue up to an additional 2,942,268 common shares through an equity shelf offering program (the “shelf offering”). Under the shelf offering, the Fund, subject to market conditions, may raise additional capital from time to time and in varying amounts and offering methods at a net price at or above the Fund’s net asset value per common share. During the six months ended March 31, 2021, the Fund did not sell any common shares through its shelf offering. During the year ended September 30, 2020, the Fund sold 44,845 common shares and received proceeds (net of offering costs) of $701,424 through its shelf offering. The net proceeds in excess of the net asset value of the shares sold were $7,960. Offering costs (other than the applicable sales commissions) incurred in connection with the shelf offering were borne directly by EVM. Eaton Vance Distributors, Inc. (EVD), an affiliate of EVM, is the distributor of the Fund’s shares and is entitled to receive a sales commission from the Fund of 1.00% of the gross sales price per share, a portion of which is re-allowed to sales agents. The Fund was informed that the sales commissions retained by EVD during the year ended September 30, 2020 were $1,417.

In August 2012, the Board of Trustees initially approved a share repurchase program for the Fund. Pursuant to the reauthorization of the share repurchase program by the Board of Trustees in March 2019, the Fund is authorized to repurchase up to 10% of its common shares outstanding as of the last day of the prior calendar year at market prices when shares are trading at a discount to net asset value. The share repurchase program does not obligate the Fund to purchase a specific amount of shares. There were no repurchases of common shares by the Fund for the six months ended March 31, 2021 and the year ended September 30, 2020.

6  Financial Instruments

The Fund may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities. These financial instruments may include written options and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment the Fund has in particular classes of financial instruments and do not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. A summary of obligations under these financial instruments at March 31, 2021 is included in the Portfolio of Investments. At March 31, 2021, the Fund had sufficient cash and/or securities to cover commitments under these contracts.

The Fund is subject to equity price risk in the normal course of pursuing its investment objectives. The Fund writes covered call options on individual stocks above the current value of the stock to generate premium income. In writing call options on individual stocks, the Fund in effect sells potential appreciation in the value of the applicable stock above the exercise price in exchange for the option premium received. The Fund retains the risk of loss, minus the premium received, should the price of the underlying stock decline.

8  Fair Value Measurements

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

• Level 1 – quoted prices in active markets for identical investments

• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3 – significant unobservable inputs (including a fund’s own assumptions in determining the fair value of investments)

In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

9  Risks and Uncertainties

Pandemic Risk

An outbreak of respiratory disease caused by a novel coronavirus was first detected in China in late 2019 and subsequently spread internationally. This coronavirus has resulted in closing borders, enhanced health screenings, changes to healthcare service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty. Health crises caused by outbreaks, such as the coronavirus outbreak, may exacerbate other pre-existing political, social and economic risks and disrupt normal market conditions and operations. The impact of this outbreak has negatively affected the worldwide economy, the economies of individual countries, individual companies, and the market in general, and may continue to do so in significant and unforeseen ways, as may other epidemics and pandemics that may arise in the future. Any such impact could adversely affect the Fund’s performance, or the performance of the securities in which the Fund invests.

Joint Special Meeting of Shareholders (Unaudited)

The Fund held a Joint Special Meeting of Shareholders (the “Special Meeting”) with certain other Eaton Vance closed-end funds on January 7, 2021 and adjourned until January 22, 2021 for the following purpose: approval of a new investment advisory agreement with EVM (“Proposal 1”). The shareholder meeting results are as follows:

	Number of Shares(1)
	For		Against		Abstain(2)		Broker Non-Votes(2)
Proposal 1		18,132,772		595,432		1,151,617		0

⁽¹⁾  Fractional shares were voted proportionately.

⁽²⁾ All shares that were voted and votes to abstain were counted towards establishing a quorum, as were broker non-votes. (Broker non-votes are shares for which a broker returns a proxy but for which (i) the beneficial owner has not voted and (ii) the broker holding the shares does not have discretionary authority to vote on the particular matter.) Abstentions and broker non-votes had the effect of a negative vote on Proposal 1. Broker non-votes were not expected with respect to Proposal 1 because brokers are required to receive instructions from the beneficial owners or persons entitled to vote in order to submit proxies.

Board of Trustees’ Contract Approval

Overview of the Contract Review Process

Even though the following description of the Board’s (as defined below) consideration of investment advisory agreements covers multiple funds, for purposes of this shareholder report, the description is only relevant as to Eaton Vance Enhanced Equity Income Fund.

At a meeting held on November 10, 2020 (the “November Meeting”), the Board of Trustees (each, a “Board” and, collectively, the “Board”) of each closed-end Fund (each, a “Fund” and, collectively, the “Funds”⁽¹⁾) managed by Eaton Vance Management (“Eaton Vance”), including a majority of the Board members (the “Independent Trustees”) who are not “interested persons” (as defined in the Investment Company Act of 1940 (the “1940 Act”)) of the Funds or Eaton Vance, voted to approve a new investment advisory agreement between each Fund and Eaton Vance, each of which is intended to go into effect upon the completion of the Transaction (as defined below) (each, a “New Agreement” and, collectively, the “New Agreements”). The Board’s evaluative process is more fully described below. In voting its approval of the New Agreements at the November Meeting, the Board relied on an order issued by the Securities and Exchange Commission in response to the impacts of the COVID-19 pandemic that provided temporary relief from the in-person meeting requirements under Section 15 of the 1940 Act.

In voting its approval of the New Agreements, the Board of each Fund relied upon the recommendation of its Contract Review Committee, which is a committee comprised exclusively of Independent Trustees. Prior to and during meetings leading up to the November Meeting, the Contract Review Committee reviewed and discussed information furnished by Eaton Vance and Morgan Stanley, as requested by the Independent Trustees, that the Contract Review Committee considered reasonably necessary to evaluate the terms of the New Agreements and to form its recommendations. Such information included, among other things, the terms and anticipated impacts of Morgan Stanley’s pending acquisition of Eaton Vance Corp. (the “Transaction”) on the Funds and their shareholders. In addition to considering information furnished specifically to evaluate the impact of the Transaction on the Funds and their respective shareholders, the Board and its Contract Review Committee also considered information furnished for prior meetings of the Board and its committees, including, but not limited to, information provided in connection with the annual contract review process for the Funds, which most recently culminated in April 2020 (the “2020 Annual Approval Process”).

The Board of each Fund, including the Independent Trustees, concluded that the applicable New Agreement, including the fees payable thereunder, was fair and reasonable, and it voted to approve the New Agreement and to recommend that shareholders do so as well.

Shortly after the announcement of the Transaction, the Board, including all of the Independent Trustees, met with senior representatives from Eaton Vance and Morgan Stanley at its meeting held on October 13, 2020 to discuss certain aspects of the Transaction and the expected impacts of the Transaction on the Funds and their shareholders. As part of the Board’s evaluation process, counsel to the Independent Trustees, on behalf of the Contract Review Committee, requested additional information to assist the Independent Trustees in their evaluation of the New Agreements and the implications of the Transaction, as well as other contractual arrangements that may be affected by the Transaction. The Contract Review Committee considered information furnished by Eaton Vance and Morgan Stanley and their respective affiliates during meetings on November 5, 2020 and November 10, 2020.

The Contract Review Committee again met with senior representatives of Eaton Vance and Morgan Stanley at its meeting on November 10, 2020, to further discuss the approval of the New Agreements. The representatives from Eaton Vance and Morgan Stanley each made presentations to, and responded to questions from, the Independent Trustees. The Contract Review Committee considered Eaton Vance’s and Morgan Stanley’s responses related to the Transaction and specifically to the Funds, as well as information received in connection with the 2020 Annual Approval Process, with respect to its evaluation of the New Agreements. Among other information, the Board considered:

As indicated above, the Board and its Contract Review Committee also considered information received at its regularly scheduled meetings throughout the year, which included information from portfolio managers and other investment professionals of Eaton Vance regarding investment and performance matters, and considered various investment and trading strategies used in pursuing the Funds’ investment objectives. The Board also received information regarding risk management techniques employed in connection with the management of the Funds. The Board and its committees evaluated issues pertaining to industry and regulatory developments, compliance procedures, fund governance and other issues with respect to the Funds, and received reports and participated in presentations provided by Eaton Vance and its affiliates with respect to such matters.

The Contract Review Committee was advised throughout the evaluation process by Goodwin Procter LLP, independent legal counsel for the Independent Trustees. The members of the Contract Review Committee, with the advice of such counsel, exercised their own business judgment in determining the material factors to be considered in evaluating the New Agreements and the weight to be given to each such factor. The conclusions reached with respect to the New Agreements were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each Independent Trustee may have placed varying emphasis on particular factors in reaching conclusions with respect to the New Agreements.

Nature, Extent and Quality of Services

In considering whether to approve the New Agreements, the Board evaluated the nature, extent and quality of services currently provided to each Fund by Eaton Vance under the Current Agreements. In evaluating the nature, extent and quality of services to be provided by Eaton Vance under the New Agreements, the Board considered, among other information, the expected impact, if any, of the Transaction on the operations, facilities, organization and personnel of Eaton Vance, and that Morgan Stanley and Eaton Vance have advised the Board that, following the Closing, there is not expected to be any diminution in the nature, extent and quality of services provided by Eaton Vance to the Funds and their shareholders, including compliance and other non-advisory services, and that there are not expected to be any changes in portfolio management personnel as a result of the Transaction.

The Board also considered the financial resources of Morgan Stanley and Eaton Vance and the importance of having a Fund manager with, or with access to, significant organizational and financial resources. The Board considered the benefits to the Funds of being part of a larger combined organization with greater financial resources following the Closing, particularly during periods of market disruptions and volatility. In this regard, the Board considered information provided by Morgan Stanley regarding its business and operating structure, scale of operation, leadership and reputation, distribution capabilities and financial condition, as well as information on how the Funds are expected to fit within Morgan Stanley’s overall business strategy and any changes that Morgan Stanley contemplates in the short- or long-term following the Closing. The Board also noted Morgan Stanley’s and Eaton Vance’s commitment to keep the Board apprised of developments with respect to its long-term integration plans for Eaton Vance and existing Morgan Stanley affiliates and their respective personnel.

The Board considered Eaton Vance’s management capabilities, investment processes and investment performance in light of the types of investments held by each Fund, including the education, experience and number of investment professionals and other personnel who provide portfolio management, investment research, and similar services to each Fund. In particular, the Board considered the abilities and experience of Eaton Vance’s investment professionals in implementing each Fund’s investment strategies. The Board also took into account the resources dedicated to portfolio management and

20

Board of Trustees’ Contract Approval — continued

other services, the compensation methods of Eaton Vance and other factors, including the reputation and resources of Eaton Vance to recruit and retain highly qualified research, advisory and supervisory investment professionals. With respect to the recruitment and retention of key personnel, the Board noted information from Morgan Stanley and Eaton Vance regarding the benefits of joining Morgan Stanley. In addition, the Board considered the time and attention devoted to the Funds by senior management, as well as the infrastructure, operational capabilities and support staff in place to assist in the portfolio management and operations of the Funds, including the provision of administrative services. With respect to the foregoing, the Board also considered information from Eaton Vance and Morgan Stanley regarding the anticipated impact of the Transaction on such matters. The Board also considered the business-related and other risks to which Eaton Vance or its affiliates may be subject in managing the Funds and in connection with the Transaction. The Board considered the deep experience of Eaton Vance and its affiliates with managing and operating funds organized as exchange-listed closed-end funds, such as the Funds. In this regard, the Board considered, among other things, Eaton Vance’s and its affiliates’ experience with implementing leverage arrangements, monitoring and assessing trading price discounts and premiums and adhering to the requirements of securities exchanges.

The Board considered the compliance programs of Eaton Vance and relevant affiliates thereof. The Board considered compliance and reporting matters regarding, among other things, personal trading by investment professionals, disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also considered the responses of Eaton Vance and its affiliates to requests in recent years from regulatory authorities, such as the Securities and Exchange Commission and the Financial Industry Regulatory Authority. The Board also considered certain information relating to the compliance record of Morgan Stanley and its affiliates, including information requests in recent years from regulatory authorities. With respect to the foregoing, including the compliance programs of Eaton Vance, the Board noted information regarding the impact of the Transaction, as well as Eaton Vance’s and Morgan Stanley’s commitment to keep the Board apprised of developments with respect to its long-term integration plans for Eaton Vance and existing Morgan Stanley affiliates and their respective personnel.

The Board considered other administrative services provided and to be provided or overseen by Eaton Vance and its affiliates, including transfer agency and accounting services. The Board evaluated the benefits to shareholders of investing in a fund that is a part of a large fund complex offering exposure to a variety of asset classes and investment disciplines. The Board noted information that the Transaction was not expected to have any material impact on such matters in the near-term.

In evaluating the nature, extent and quality of the services to be provided under the New Agreements, the Board also considered investment performance information provided for each Fund in connection with the 2020 Annual Approval Process, as well as information provided as of a more recent date. In this regard, the Board compared each Fund’s investment performance to that of comparable funds identified by an independent data provider (the peer group), as well as appropriate benchmark indices and, for certain Funds, a custom peer group of similarly managed funds. The Board also considered, where applicable, Fund-specific performance explanations based on criteria established by the Board in connection with the 2020 Annual Approval Process and, where applicable, performance explanations as of a more recent date. In addition to the foregoing information, it was also noted that the Board has received and discussed with management information throughout the year at periodic intervals comparing each Fund’s performance against applicable benchmark indices and peer groups. In addition, the Board considered each Fund’s performance in light of overall financial market conditions. Where a Fund’s relative underperformance to its peers was significant during one or more specified periods, the Board noted the explanations from Eaton Vance concerning the Fund’s relative performance versus the peer group.

After consideration of the foregoing factors, among others, and based on their review of the materials provided and the assurances received from, and recommendations of, Eaton Vance and Morgan Stanley, the Board determined that the Transaction was not expected to adversely affect the nature, extent and quality of services provided to the Funds by Eaton Vance and its affiliates and that the Transaction was not expected to have an adverse effect on the ability of Eaton Vance and its affiliates to provide those services. The Board concluded that the nature, extent and quality of services expected to be provided by Eaton Vance, taken as a whole, are appropriate and expected to be consistent with the terms of the New Agreements.

Management Fees and Expenses

The Board considered contractual fee rates payable by each Fund for advisory and administrative services (referred to collectively as “management fees”) in connection with the 2020 Annual Approval Process, as well as information provided as of a more recent date. As part of its review, the Board considered each Fund’s management fees and total expense ratio over various periods, as compared to those of comparable funds, before and after giving effect to any undertaking to waive fees or reimburse expenses.

The Board also considered factors, and, where applicable, certain Fund-specific factors, that had an impact on a Fund’s total expense ratio relative to comparable funds, as identified by Eaton Vance in response to inquiries from the Contract Review Committee. The Board considered that the New Agreement does not change a Fund’s management fee rate or the computation method for calculating such fees, including any separately executed permanent contractual management fee reduction currently in place for the Fund.

The Board also received and considered, where applicable, information about the services offered and the fee rates charged by Eaton Vance to other types of accounts with investment objectives and strategies that are substantially similar to and/or managed in a similar investment style as a Fund. In this regard, the Board received information about the differences in the nature and scope of services Eaton Vance provides to the Funds as compared to other types of accounts and the material differences in compliance, reporting and other legal burdens and risks to Eaton Vance as between each Fund and other types of accounts.

Board of Trustees’ Contract Approval — continued

After considering the foregoing information, and in light of the nature, extent and quality of the services expected to be provided by Eaton Vance, the Board concluded that the management fees charged for advisory and related services are reasonable with respect to its approval of the New Agreements.

Profitability and “Fall-Out” Benefits

During the 2020 Annual Approval Process, the Board considered the level of profits realized by Eaton Vance and relevant affiliates thereof in providing investment advisory and administrative services to the Funds and to all Eaton Vance funds as a group. The Board considered the level of profits realized without regard to marketing support or other payments by Eaton Vance and its affiliates to third parties in respect of distribution or other services. In light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by Eaton Vance and its affiliates were not deemed to be excessive by the Board.

The Board noted that Morgan Stanley and Eaton Vance are expected to realize, over time, cost savings from the Transaction based on eliminating duplicate corporate overhead expenses. The Board considered, however, information from Eaton Vance and Morgan Stanley that such cost savings are not expected to be realized immediately upon the Closing and that, accordingly, there are currently no specific expected changes in the levels of profitability associated with the advisory and other services provided to the Funds that are contemplated as a result of the Transaction. The Board noted that it will continue to receive information regarding profitability during its annual contract review processes, including the extent to which cost savings and/or other efficiencies result in changes to profitability levels.

The Board also considered direct or indirect fall-out benefits received by Eaton Vance and its affiliates in connection with their respective relationships with the Funds, including the benefits of research services that may be available to Eaton Vance and its affiliates as a result of securities transactions effected for the Funds and other investment advisory clients. In evaluating the fall-out benefits to be received by Eaton Vance and its affiliates under the New Agreements, the Board considered whether the Transaction would have an impact on the fall-out benefits currently realized by Eaton Vance and its affiliates in connection with services provided pursuant to the Current Agreements.

The Board of each Fund considered that Morgan Stanley may derive reputational and other benefits from its ability to use the names of Eaton Vance and its affiliates in connection with operating and marketing the Funds. The Board considered that the Transaction, if completed, would significantly increase Morgan Stanley’s assets under management and expand Morgan Stanley’s investment capabilities.

Economies of Scale

The Board also considered the extent to which Eaton Vance and its affiliates, on the one hand, and the Funds, on the other hand, can expect to realize benefits from economies of scale as the assets of the Funds increase. The Board acknowledged the difficulty in accurately measuring the benefits resulting from economies of scale, if any, with respect to the management of any specific Fund or group of funds. As part of the 2020 Annual Approval Process, the Board reviewed data summarizing the increases and decreases in the assets of the Funds and of all Eaton Vance funds as a group over various time periods, and evaluated the extent to which the total expense ratio of each Fund and the profitability of Eaton Vance and its affiliates may have been affected by such increases or decreases.

The Board noted that Morgan Stanley and Eaton Vance are expected to benefit from possible growth of the Funds resulting from enhanced distribution capabilities, including with respect to the Funds’ potential access to Morgan Stanley’s institutional client base. Based upon the foregoing, the Board concluded that the Funds currently share in the benefits from economies of scale, if any, when they are realized by Eaton Vance, and that the Transaction is not expected to impede a Fund from continuing to benefit from any future economies of scale realized by Eaton Vance. The Board also considered the fact that the Funds are not continuously offered in the same manner as an open-end fund and that, notwithstanding that certain Funds (including Eaton Vance Enhanced Equity Income Fund) are authorized to issue additional common shares through a shelf offering, the Funds’ assets may not increase materially in the foreseeable future.

Conclusion

Based on its consideration of the foregoing, and such other information it deemed relevant, including the factors and conclusions described above, the Contract Review Committee recommended to the Board approval of the New Agreements. Based on the recommendation of the Contract Review Committee, the Board, including a majority of the Independent Trustees, unanimously voted to approve the New Agreements for the Funds and recommended that shareholders approve the New Agreements.

Eaton Vance Funds

IMPORTANT NOTICES

Delivery of Shareholder Documents.  The Securities and Exchange Commission (SEC) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders. American Stock Transfer & Trust Company, LLC (“AST”), the closed-end funds transfer agent, or your financial intermediary, may household the mailing of your documents indefinitely unless you instruct AST, or your financial intermediary, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact AST or your financial intermediary. Your instructions that householding not apply to delivery of your Eaton Vance documents will typically be effective within 30 days of receipt by AST or your financial intermediary.

Portfolio Holdings.  Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) files a schedule of portfolio holdings on Part F to Form N-PORT with the SEC. Certain information filed on Form N-PORT may be viewed on the Eaton Vance website at www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC’s website at www.sec.gov.

Proxy Voting.  From time to time, funds are required to vote proxies related to the securities held by the funds. The Eaton Vance Funds or their underlying Portfolios (if applicable) vote proxies according to a set of policies and procedures approved by the Funds’ and Portfolios’ Boards. You may obtain a description of these policies and procedures and information on how the Funds or Portfolios voted proxies relating to portfolio securities during the most recent 12-month period ended June 30, without charge, upon request, by calling 1-800-262-1122 and by accessing the SEC’s website at www.sec.gov.

Share Repurchase Program.  The Fund’s Board of Trustees has approved a share repurchase program authorizing the Fund to repurchase up to 10% of its common shares outstanding as of the last day of the prior calendar year in open-market transactions at a discount to net asset value. The repurchase program does not obligate the Fund to purchase a specific amount of shares. The Fund’s repurchase activity, including the number of shares purchased, average price and average discount to net asset value, is disclosed in the Fund’s annual and semi-annual reports to shareholders.

Additional Notice to Shareholders.  If applicable, a Fund may also redeem or purchase its outstanding preferred shares in order to maintain compliance with regulatory requirements, borrowing or rating agency requirements or for other purposes as it deems appropriate or necessary.

Closed-End Fund Information.  Eaton Vance closed-end funds make fund performance data and certain information about portfolio characteristics available on the Eaton Vance website shortly after the end of each month. Other information about the funds is available on the website. The funds’ net asset value per share is readily accessible on the Eaton Vance website. Portfolio holdings for the most recent month-end are also posted to the website approximately 30 days following the end of the month. This information is available at www.eatonvance.com on the fund information pages under “Individual Investors — Closed-End Funds”.
