Commodity Futures Trading Commission Registration. Effective December 31, 2012, the Commodity Futures Trading Commission (“CFTC”) adopted certain regulatory changes 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 Fund has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act. 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 and 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 $0.1108 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 Performance¹

Economic and Market Conditions

U.S. stock markets moved steadily higher over the 12-month period ended December 31, 2017, due to an extended rally that began with President Trump’s election victory. Strong global economic growth and rising corporate profits helped drive market gains.

When the period began, U.S. stock markets were on the upswing following the U.S. election outcome in November 2016. Those markets slipped in March 2017, as the failure of the President’s health care bill in Congress raised concerns about prospects for the rest of the administration’s economic policy agenda, including tax reform and infrastructure spending. But U.S. stock markets, backed by positive economic reports, quickly regained their upward momentum. Citing the strengthening economy, the U.S. Federal Reserve (the Fed) raised its benchmark interest rate in March 2017 and again in June 2017.

U.S. equity markets briefly retreated in August 2017 amid the North Korea stand-off and the devastation left by Hurricane Harvey in Texas. Those markets soon rebounded, however, with major U.S. indexes reaching multiple record highs in the final three months of the period ended December 31, 2017. Investors anticipated and then cheered passage of the Republican tax reform package championed by President Trump. Deep cuts in the corporate tax rate, a key element of the tax bill, raised expectations for higher corporate earnings. In December, the Fed increased interest rates for the third and final time in 2017. As with the two previous rate hikes, investors took the announcement in stride and continued to push domestic stock prices higher. In terms of economic sectors, information technology and financials led the U.S. market’s advance during the period ended December 31, 2017.

For the 12-month period ended December 31, 2017, all major U.S. stock indexes recorded double-digit returns. The blue-chip Dow Jones Industrial Average² rose 28.11%, while the broader U.S. equity market, as represented by the S&P 500 Index, returned 21.83%. The technology-laden NASDAQ Composite Index delivered a 29.64% gain. Large-cap U.S. stocks, as measured by the S&P 500 Index, outperformed their small-cap counterparts as measured by the Russell 2000^® Index during the period. Growth stocks outpaced value stocks within both the large- and small-cap categories, as measured by the Russell growth and value indexes.

Fund Performance

For the 12-month period ended December 31, 2017, Eaton Vance Tax-Managed Buy-Write Opportunities Fund (the Fund) had a total return of 16.93% at net asset value (NAV), underperforming the 21.83% return of its primary benchmark,

the S&P 500 Index (the Index), the 32.99% return of the NASDAQ–100 Index, and the 18.93% return of the CBOE NASDAQ–100 BuyWrite Index, but outperforming the 13.00% return of the CBOE S&P 500 BuyWrite Index.

The Fund’s common stock portfolio outperformed the Index during the period and thus helped relative Fund performance, while the Fund’s options overlay strategy was the largest detractor from Fund performance versus the Index.

The Fund employs an options strategy of writing (selling) stock index call options on a portion of its underlying common stock portfolio. The options strategy, which is designed to help limit the Fund’s exposure to market volatility and to provide current income, proved disadvantageous during a 12-month period marked by low volatility in the equity market and strong performance of the Index, which delivered positive returns for every month of the calendar year for the first time in 90 years. Low volatility depressed the premiums for selling call options, and the Fund’s options underperformed the Index, especially during its sharp rallies in February 2017 and September through November 2017. However, option selection and diversification⁶ helped the Fund outperform the CBOE S&P 500 BuyWrite Index for the period.

Within the Fund’s common stock portfolio, performance versus the Index was helped by an overweight, relative to the Index, in the information technology sector; stock selection in the consumer discretionary sector; and an underweight and stock selection in the energy sector. Within information technology, overweighting Apple, Inc. (Apple) contributed to relative performance. The stock was driven upward by anticipation of the launch of the tenth anniversary iPhone and by growth in Apple’s services business as its software ecosystem expanded. In the consumer discretionary sector, the Fund’s overweight position in online retailer and cloud computing firm Amazon. com, Inc. (Amazon) appreciated as the firm reported accelerating growth and profitability. Gains were driven by Amazon’s market share growth and its expansion into new areas, including its acquisition during the period of supermarket chain Whole Foods Market.

In contrast, stock selection in the health care sector detracted from Fund performance versus the Index. The Fund’s overweight holding in biotech firm Celgene Corp. fell in price after a high-profile drug in its development pipeline failed a clinical trial and was subsequently abandoned. Elsewhere in the sector, overweighting Gilead Sciences, Inc. (Gilead), another biotech company, also proved detrimental to relative performance. The stock delivered modestly positive performance but underperformed the overall health care sector in the Index, due to investor concerns about weakness in Gilead’s drug development pipeline.

See Endnotes and Additional Disclosures in this report.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributions reinvested and include management fees and other expenses. Fund performance at market price will differ from its results at NAV due to factors such as changing perceptions about the Fund, market conditions, fluctuations in supply and demand for Fund shares, or changes in Fund distributions. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance 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.

Tax-Managed Buy-Write Opportunities Fund

December 31, 2017

Notes to Financial Statements

1 Significant Accounting Policies

Eaton Vance Tax-Managed Buy-Write Opportunities 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 and gains, 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 asked prices therefore 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 asked prices.

Derivatives. U.S. exchange-traded options are valued at the mean between the bid and asked 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.

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 fairly reflects the security’s value, or 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 condition, 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 December 31, 2017, 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 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.

F 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 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.

G 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 strike 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 strike 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.

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.

The tax character of distributions declared for the years ended December 31, 2017 and December 31, 2016 was as follows:


	Year Ended December 31,
	2017		2016

Distributions declared from:
Ordinary income	$	5,798,407	$	7,490,957
Long-term capital gains	$	—	$	27,792,712
Tax return of capital	$	81,339,037	$	49,648,547

During the year ended December 31, 2017, accumulated net realized loss was decreased by $60,595 and accumulated undistributed net investment income was decreased by $60,595 due to differences between book and tax accounting, primarily for distributions from real estate investment trusts (REITs) and return of capital distributions from securities. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of December 31, 2017, the components of distributable earnings (accumulated losses) on a tax basis were as follows:


Deferred capital losses	$	(4,643,349	)
Net unrealized appreciation	$	738,969,069

The differences between components of distributable earnings (accumulated losses) on a tax basis and the amounts reflected in the Statement of Assets and Liabilities are primarily due to wash sales, option contracts, distributions from REITs, tax straddle transactions and return of capital distributions from securities.

At December 31, 2017, the Fund, for federal income tax purposes, had deferred capital losses of $4,643,349 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 December 31, 2017, $4,643,349 are short-term.

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Fund at December 31, 2017, as determined on a federal income tax basis, were as follows:



Aggregate cost	$	287,233,492

Gross unrealized appreciation	$	739,466,194
Gross unrealized depreciation		(497,125	)

Net unrealized appreciation	$	738,969,069

3 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Eaton Vance Management (EVM) as compensation for management and investment advisory services rendered to the Fund. 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 year ended December 31, 2017, the Fund’s investment adviser fee amounted to $9,517,058. Pursuant to a sub-advisory agreement, EVM has delegated a portion of the investment management to Parametric Portfolio Associates LLC (Parametric), a majority-owned subsidiary of Eaton Vance Corp. EVM pays Parametric a portion of its investment adviser fee for sub-advisory services provided to the Fund. EVM also serves as administrator of the Fund, but receives no compensation.

In May 2017, an equity options trader formerly employed by EVM pled guilty to criminal charges of defrauding EVM and certain Eaton Vance-sponsored funds, including the Fund, by diverting Fund trading profits to an undisclosed personal brokerage account. The damages to the Fund as a result of this activity were determined to be $13,223, including interest. During the year ended December 31, 2017, EVM paid this amount to the Fund. The Fund also filed a claim under the Fund’s and EVM’s joint fidelity bond, and the reimbursement made under the fidelity bond was paid to EVM. The amount of the payment is reported on the Fund’s Statement of Operations under the caption “Net realized gain (loss) — Payment by affiliate.” This payment had an impact on the Fund’s total return at net asset value of less than 0.01% for the year ended December 31, 2017.

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 year ended December 31, 2017, 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 $38,234,041 and $122,884,201, respectively, for the year ended December 31, 2017.

5 Common Shares of Beneficial Interest and Shelf Offering

Common shares issued by the Fund pursuant to its dividend reinvestment plan for the years ended December 31, 2017 and December 31, 2016 were 189,129 and 163,528, respectively.

The Board of Trustees of the Fund approved the continuation of the Fund’s share repurchase program that has been in effect since August 6, 2012. Pursuant to the terms of the reauthorization of the program, the Fund may repurchase up to 10% of its common shares outstanding as of September 30, 2013 in open market transactions at a discount to net asset value (NAV). The terms of the reauthorization increased the number of shares available for repurchase. The 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 years ended December 31, 2017 and December 31, 2016.

Pursuant to a registration statement filed with and declared effective on April 5, 2017 by the SEC, the Fund is authorized to issue up to an additional 7,678,962 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 year ended December 31, 2017, the Fund sold 4,005,439 common shares and received proceeds (net of offering costs) of $60,883,895 through its shelf offering. The net proceeds in excess of the net asset value of the shares sold were $2,241,291. 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 December 31, 2017 were $123,001.

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 December 31, 2017 is included in the Portfolio of Investments. At December 31, 2017, 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 index call options above the current value of the index to generate premium income. In writing index call options, the Fund in effect, sells potential appreciation in the value of the applicable index 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 index decline.

The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) and whose primary underlying risk exposure is equity price risk at December 31, 2017 was as follows:


	Fair Value
Derivative	Asset Derivative		Liability Derivative⁽¹⁾

Written options	$	—	$	(5,894,200	)

⁽¹⁾	Statement of Assets and Liabilities location: Written options outstanding, at value.

The effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) on the Statement of Operations and whose primary underlying risk exposure is equity price risk for the year ended December 31, 2017 was as follows:

⁽¹⁾	Statement of Operations location: Net realized gain (loss) – Written options.

⁽²⁾	Statement of Operations location: Change in unrealized appreciation (depreciation) – Written options.

The average number of written options contracts outstanding during the year ended December 31, 2017, which is indicative of the volume of this derivative type, was 2,857 contracts.

7 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.

Notes to Financial Statements — continued

At December 31, 2017, the hierarchy of inputs used in valuing the Fund’s investments and open derivative instruments, which are carried at value, were as follows:


Asset Description	Level 1			Level 2		Level 3		Total

Common Stocks	$	1,026,202,561	*	$	—	$	—	$	1,026,202,561

Total	$	(5,894,200	)	$	—	$	—	$	(5,894,200	)

*	The level classification by major category of investments is the same as the category presentation in the Portfolio of Investments.

The Fund held no investments or other financial instruments as of December 31, 2016 whose fair value was determined using Level 3 inputs. At December 31, 2017, there were no investments transferred between Level 1 and Level 2 during the year then ended.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of Eaton Vance Tax-Managed Buy-Write Opportunities Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Eaton Vance Tax-Managed Buy-Write Opportunities Fund (the “Fund”), including the portfolio of investments, as of December 31, 2017, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of December 31, 2017, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of December 31, 2017, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Dividend Reinvestment Plan

The Fund offers a dividend reinvestment plan (Plan) pursuant to which shareholders may elect to have distributions automatically reinvested in common shares (Shares) of the Fund. You may elect to participate in the Plan by completing the Dividend Reinvestment Plan Application Form. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you by American Stock Transfer & Trust Company, LLC (AST) as dividend paying agent. On the distribution payment date, if the NAV per Share is equal to or less than the market price per Share plus estimated brokerage commissions, then new Shares will be issued. The number of Shares shall be determined by the greater of the NAV per Share or 95% of the market price. Otherwise, Shares generally will be purchased on the open market by AST, the Plan agent (Agent). Distributions subject to income tax (if any) are taxable whether or not Shares are reinvested.

If your Shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the Plan on your behalf. If the nominee does not offer the Plan, you will need to request that the Fund’s transfer agent re-register your Shares in your name or you will not be able to participate.

The Agent’s service fee for handling distributions will be paid by the Fund. Plan participants will be charged their pro rata share of brokerage commissions on all open-market purchases.

Plan participants may withdraw from the Plan at any time by writing to the Agent at the address noted on the following page. If you withdraw, you will receive Shares in your name for all Shares credited to your account under the Plan. If a participant elects by written notice to the Agent to sell part or all of his or her Shares and remit the proceeds, the Agent is authorized to deduct a $5.00 fee plus brokerage commissions from the proceeds.

If you wish to participate in the Plan and your Shares are held in your own name, you may complete the form on the following page and deliver it to the Agent. Any inquiries regarding the Plan can be directed to the Agent at 1-866-439-6787.

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 advisor, may household the mailing of your documents indefinitely unless you instruct AST, or your financial advisor, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact AST or your financial advisor. 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 advisor.

Portfolio Holdings. Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) will file a schedule of portfolio holdings on Form N-Q with the SEC for the first and third quarters of each fiscal year. The Form N-Q will be available 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. Form N-Q may also be reviewed and copied at the SEC’s public reference room in Washington, D.C. (call 1-800-732-0330 for information on the operation of the public reference room).

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 outstanding common shares as of the approved date 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”.

Item 2. Code of Ethics

The registrant has adopted a code of ethics applicable to its Principal Executive Officer, Principal Financial Officer and Principal Accounting Officer. The registrant undertakes to provide a copy of such code of ethics to any person upon request, without charge, by calling 1-800-262-1122. The registrant has not amended the code of ethics as described in Form N-CSR during the period covered by this report. The registrant has not granted any waiver, including an implicit waiver, from a provision of the code of ethics as described in Form N-CSR during the period covered by this report.

Item 3. Audit Committee Financial Expert

The registrant’s Board has designated William H. Park, an independent trustee, as its audit committee financial expert. Mr. Park is a certified public accountant who is a private investor. Previously, he served as a consultant, as the Chief Financial Officer of Aveon Group, L.P. (an investment management firm), as the Vice Chairman of Commercial Industrial Finance Corp. (specialty finance company), as President and Chief Executive Officer of Prizm Capital Management, LLC (investment management firm), as Executive Vice President and Chief Financial Officer of United Asset Management Corporation (an institutional investment management firm) and as a Senior Manager at Price Waterhouse (now PricewaterhouseCoopers) (an independent registered public accounting firm).

Item 4. Principal Accountant Fees and Services

Rule 2-01(c)(1)(ii)(A) of Regulation S-X (the “Loan Rule”) prohibits an accounting firm, such as the Fund’s principal accountant, Deloitte & Touche LLP (“D&T”), from having certain financial relationships with their audit clients and affiliated entities. Specifically, the Loan Rule provides, in relevant part, that an accounting firm generally would not be independent if it or a “covered person” of the accounting firm (within the meaning of applicable SEC rules relating to auditor independence) receives a loan from a lender that is a “record or beneficial owner of more than ten percent of the audit client’s equity securities.” Based on information provided to the Audit Committee of the Board of Trustees (the “Audit Committee”) of the Eaton Vance family of funds by D&T, certain relationships between D&T and its affiliates (“Deloitte Entities”) and one or more lenders who are record owners of shares of one or more funds within the Eaton Vance family of funds (the “Funds”) implicate the Loan Rule, calling into question D&T’s independence with respect to the Funds. The Funds are providing this disclosure to explain the facts and circumstances as well as D&T’s conclusions concerning D&T’s objectivity and impartiality with respect to the audits of the Funds notwithstanding the existence of one or more breaches of the Loan Rule.

On June 20, 2016, the U.S. Securities and Exchange Commission (the “SEC”) issued no-action relief to another mutual fund complex (see Fidelity Management & Research Company et al., No-Action Letter (June 20, 2016) (the “No-Action Letter”)) related to an auditor independence issue arising under the Loan Rule. In the No-Action Letter, the SEC indicated that it would not recommend enforcement action against the fund group if the auditor is not in compliance with the Loan Rule provided that: (1) the auditor has complied with PCAOB Rule 3526(b)(1) and 3526(b)(2); (2) the auditor’s non-compliance under the Loan Rule is with respect to certain lending relationships; and (3) notwithstanding such non-compliance, the auditor has concluded that it is objective and impartial with respect to the issues encompassed within its engagement as auditor of the funds.

Based on information provided by D&T to the Audit Committee, the requirements of the No-Action Letter appear to be met with respect to D&T’s lending relationships described above. Among other things, D&T has advised the Audit Committee of its conclusion that the consequences of the breach of the Loan Rule have been satisfactorily addressed, that D&T’s objectivity and impartiality in the planning and conduct of the audits of the Fund’s financial statements has not been compromised and that, notwithstanding the breach, D&T is in a position to continue as the auditor for the Funds and D&T does not believe any actions need to be taken with respect to previously issued reports by D&T. D&T has advised the Audit Committee that these conclusions were based in part on its consideration of the No-Action Letter and other relevant information communicated to the Audit Committee.

(a) –(d)

The following table presents the aggregate fees billed to the registrant for the registrant’s fiscal years ended December 31, 2016 and December 31, 2017 by 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.


Fiscal Years Ended	12/31/16		12/31/17
Audit Fees	$	50,990	$	50,990
Audit-Related Fees⁽¹⁾	$	0	$	0
Tax Fees⁽²⁾	$	9,165	$	10,802
All Other Fees⁽³⁾	$	0	$	0

Total	$	60,155	$	61,792

⁽¹⁾	Audit-related fees consist of the aggregate fees billed for assurance and related services that are reasonably related to the performance of the audit of financial statements and are not reported under the category of audit fees.

⁽²⁾	Tax fees consist of the aggregate fees billed for professional services rendered by the principal accountant relating to tax compliance, tax advice, and tax planning and specifically include fees for tax return preparation.

⁽³⁾	All other fees consist of the aggregate fees billed for products and services provided by the principal accountant other than audit, audit-related, and tax services.

(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.

(e)(2) No services described in paragraphs (b)-(d) above were approved by the registrant’s audit committee pursuant to the “de minimis exception” set forth in Rule 2-01(c)(7)(i)(C) of Regulation S-X.

(f) Not applicable.

(g) The following table presents (i) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed to the registrant by D&T for the registrant’s fiscal years ended December 31, 2016 and December 31, 2017; and (ii) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed to the Eaton Vance organization by D&T for the same time periods.


Fiscal Years Ended	12/31/16		12/31/17
Registrant	$	9,165	$	10,802
Eaton Vance⁽¹⁾	$	46,000	$	148,018

⁽¹⁾	The investment adviser to the registrant, as well as any of its affiliates that provide ongoing services to the registrant, are subsidiaries of Eaton Vance Corp.

(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.

Item 5. Audit Committee of Listed Registrants

The registrant has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Securities and Exchange Act of 1934, as amended. George J. Gorman (Chair), Valerie A. Mosley, William H. Park and Scott E. Wennerholm are the members of the registrant’s audit committee.

Item 6. Schedule of Investments

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 Trustees of the Trust 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 Fund’s proxy voting records from time to time and will annually consider approving the Policies for the upcoming year. 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’s Special Committee except as contemplated under the Fund Policy. The Board’s Special Committee will instruct the investment adviser on the appropriate course of action.

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 and/or refer then back to the investment adviser pursuant to the Policies. It is generally the policy of the investment adviser to vote in accordance with the recommendation of the Agent. The Agent shall refer to the investment adviser proxies relating to mergers and restructurings, and the disposition of assets, termination, liquidation and mergers contained in mutual fund proxies. The investment adviser will normally vote against anti-takeover measures and other proposals designed to limit the ability of shareholders to act on possible transactions, except in the case of closed-end management investment companies. The investment adviser generally supports management on social and environmental proposals. The investment adviser may abstain from voting from time to time

where it determines that the costs associated with voting a proxy outweighs the benefits derived from exercising the right to vote or the economic effect on shareholders interests or the value of the portfolio holding is indeterminable or insignificant.

In addition, the investment adviser will monitor situations that may result in a conflict of interest between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund by maintaining a list of significant existing and prospective corporate clients. The investment adviser’s personnel responsible for reviewing and voting proxies on behalf of the Fund will report any proxy received or expected to be received from a company included on that list to the personal of the investment adviser identified in the Policies. If such personnel expects to instruct the Agent to vote such proxies in a manner inconsistent with the guidelines of the Policies or the recommendation of the Agent, the personnel will consult with members of senior management of the investment adviser to determine if a material conflict of interests exists. If it is determined that a material conflict does exist, the investment adviser will seek instruction on how to vote from the Special Committee.

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. EVM has engaged its affiliate, Parametric Portfolio Associates LLC (“Parametric”), as the sub-adviser of the Fund. Michael A. Allison and Thomas C. Seto comprise the investment team responsible for the overall and day-to-day management of the Fund’s investments.

Mr. Allison is a Vice President of EVM, is a member of EVM’s Equity Strategy Committee and has been a portfolio manager of the Fund since June 2015. Mr. Seto is Head of Investment Management at Parametric’s Seattle Investment Center and has been a portfolio manager of the Fund since April 2005. Messrs. Allison and Seto have managed other Eaton Vance portfolios for more than five years. This information is provided as of the date of filing this report.

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.


	Number of All Accounts		Total Assets of All Accounts			Number of Accounts Paying a Performance Fee		Total Assets of Accounts Paying a Performance Fee
Michael A. Allison

Registered Investment Companies		16	$	31,588.1			0	$	0
Other Pooled Investment Vehicles		14	$	18,730.5	⁽¹⁾		0	$	0

Other Accounts		17,174	$	92,429.9	⁽³⁾		2	$	210.2

⁽¹⁾	Certain of these “Other Pooled Investment Vehicles” invest a substantial portion of their assets either in a registered investment company or in a separate pooled investment vehicle managed by this portfolio manager or another Eaton Vance portfolio manager.

⁽²⁾	This portfolio manager provides investment advice with respect to only a portion of the total assets of certain of these accounts. Only the assets allocated to this portfolio manager as of the Fund’s most recent fiscal year end are reflected in the table.

⁽³⁾	For “Other Accounts” that are part of a wrap account program, the number of accounts is the number of sponsors for which the portfolio manager provides advisory services rather than the number of individual customer accounts within each wrap account program.

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


Portfolio Manager		Dollar Range of Equity Securities Beneficially Owned in the Fund
Michael A. Allison		$1 - $10,000
Thomas C. Seto		None

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 or the sub-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 and Parametric have adopted several policies and procedures designed to address these potential conflicts including a code of ethics and policies that govern the investment adviser’s and sub-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

Compensation of EVM’s portfolio managers and other investment professionals has three primary components: (1) a base salary, (2) an annual cash bonus, and (3) annual non-cash compensation consisting of options to purchase shares of Eaton Vance Corp.’s (“EVC’s”) nonvoting common stock, restricted shares of EVC’s nonvoting common stock and a Deferred Alpha Incentive Plan, which pays a deferred cash award tied to future excess returns in certain equity strategy portfolios. EVM’s investment professionals also receive certain retirement, insurance and other benefits that are broadly available to EVM’s employees. Compensation of EVM’s investment professionals is reviewed primarily on an annual basis. Cash bonuses, stock-based compensation awards, and adjustments in base salary are typically paid or put into effect at or shortly after the October 31st fiscal year end of EVC.

Method to Determine Compensation. EVM compensates its portfolio managers based primarily on the scale and complexity of their portfolio responsibilities and the total return performance of managed funds and accounts versus the benchmark(s) stated in the prospectus, as well as an appropriate peer group (as described below). In addition to rankings within peer groups of funds on the basis of absolute performance, consideration may also be given to relative risk-adjusted performance. Risk-adjusted performance measures include, but are not limited to, the Sharpe ratio (Sharpe ratio uses standard deviation and excess return to determine reward per unit of risk). Performance is normally based on periods ending on the September 30th preceding fiscal year end. Fund performance is normally evaluated primarily versus peer groups of funds as determined by Lipper Inc. and/or Morningstar, Inc. When a fund’s peer group as determined by Lipper or Morningstar is deemed by EVM’s management not to provide a fair comparison, performance may instead be evaluated primarily against a custom peer group or market index. In evaluating the performance of a fund and its manager, primary emphasis is normally placed on three-year performance, with secondary consideration of performance over longer and shorter periods. A portion of the compensation payable to equity portfolio managers and investment professionals will be determined based on the ability of one or more accounts managed by such manager to achieve a specified target average annual gross return over a three year period in excess of the account benchmark. The cash bonus to be payable at the end of the three year term will be established at the inception of the term and will be adjusted positively or negatively to the extent that the average annual gross return varies from the specified target return. For funds that are tax-managed or otherwise have an objective of after-tax returns, performance is measured net of taxes. For other funds, performance is evaluated on a pre-tax basis. For funds with an investment objective other than total return (such as current income), consideration will also be given to the fund’s success in achieving its objective. For managers responsible for multiple funds and accounts, investment performance is evaluated on an aggregate basis, based on averages or weighted averages among managed funds and accounts. Funds and accounts that have performance-based advisory fees are not accorded disproportionate weightings in measuring aggregate portfolio manager performance.

The compensation of portfolio managers with other job responsibilities (such as heading an investment group or providing analytical support to other portfolios) will include consideration of the scope of such responsibilities and the managers’ performance in meeting them.

EVM seeks to compensate portfolio managers commensurate with their responsibilities and performance, and competitive with other firms within the investment management industry. EVM participates in investment-industry compensation surveys and utilizes survey data as a factor in determining salary, bonus and stock-based compensation levels for portfolio managers and other investment professionals. Salaries, bonuses and stock-based compensation are also influenced by the operating performance of EVM and its parent company. The overall annual cash bonus pool is generally based on a substantially fixed percentage of pre-bonus adjusted operating income. While the salaries of EVM’s portfolio managers are comparatively fixed, cash bonuses and stock-based compensation may fluctuate significantly from year to year, based on changes in manager performance and other factors as described herein. For a high performing portfolio manager, cash bonuses and stock-based compensation may represent a substantial portion of total compensation.

Compensation Structure for Parametric

Compensation of Parametric portfolio managers and other investment professionals has three primary components: (1) a base salary, (2) a cash bonus, and (3) annual stock-based compensation consisting of options to purchase shares of EVC nonvoting common stock, restricted shares of EVC nonvoting common stock and, for certain individuals, grants of profit participation interests in Parametric. Parametric investment professionals also receive certain retirement, insurance and other benefits that are broadly available to Parametric employees. Compensation of Parametric investment professionals is reviewed primarily on an annual basis. Stock-based compensation awards and adjustments in base salary and bonus are typically paid and/or put into effect at or shortly after fiscal year-end.

Method to Determine Compensation. Parametric seeks to compensate portfolio managers commensurate with their responsibilities and performance, and competitive with other firms within the investment management industry. The performance of portfolio managers is evaluated primarily based on success in achieving portfolio objectives for managed funds and accounts. The compensation of portfolio managers with other job responsibilities (such as product development) will include consideration of the scope of such responsibilities and the managers’ performance in meeting them.

Salaries, bonuses and stock-based compensation are also influenced by the operating performance of Parametric and EVC, its parent company. Cash bonuses available overall are determined based on a target percentage of Parametric profits. While the salaries of Parametric portfolio managers are comparatively fixed, cash bonuses and stock-based compensation may fluctuate substantially from year to year, based on changes in financial performance and other factors.
