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 and Parametric Portfolio Associates LLC (Parametric), sub-adviser to the Fund, are registered with the CFTC as commodity pool operators. The adviser and Parametric are also registered as commodity trading advisors.

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 $0.0727 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

The 12-month period that began January 1, 2020, included some of the best and worst equity performances in over a decade.

As the period opened, news of a novel coronavirus outbreak in China began to raise investor concerns. As the virus turned into a global pandemic in February and March, it ended the longest-ever U.S. economic expansion and triggered a global economic slowdown. Equity markets along with credit markets plunged in value amid unprecedented volatility.

In response, the U.S. Federal Reserve announced two emergency rate cuts in March 2020 — lowering the federal funds rate to 0.00%-0.25% — along with other measures designed to shore up the markets. Across the globe, other central banks and governments launched aggressive monetary and fiscal responses to help mitigate the economic effects of what became known as COVID-19. These actions helped calm investment markets and initiated a global equity rally that began in late March and lasted through August.

In the second quarter of 2020, U.S. stocks reported their best quarterly returns since 1998 — on the heels of the worst first quarter for American stocks since the 2007-2008 global financial crisis. As with U.S. equities, overseas stock indexes reflected investor optimism as economies started to emerge from COVID-19 lockdowns and factories resumed production.

In September and October, however, the equity rally stalled as the pandemic appeared to increase its drag on the global economy. Across Europe, nations that seemed to have beaten back the coronavirus during the summer initiated new lockdowns to combat a second wave of infections. In the U.S., coronavirus cases were on the rise in virtually every state. Reflecting an increasingly grim economic outlook for fall and winter, most major global stock indexes reported negative returns in September and October.

In the closing months of the period, however, stocks reversed course again. Joe Biden’s victory in the November U.S. presidential election eased political uncertainties that had dogged investment markets through much of the fall. Additionally, the announcement that two COVID-19 vaccine candidates had proven more than 90% effective in late-stage trials boosted investor optimism that powered a global stock rally. The MSCI World Index and MSCI EAFE Index reported double-digit gains in November, while the blue-chip Dow Jones Industrial Average turned in its best month since January 1987, and the S&P 500^® Index advanced nearly 11% for the month. As both vaccines were approved for emergency use in numerous countries and vaccinations began in December 2020, an eventual end to the pandemic seemed to be in sight and the global rally continued.

For the period as a whole, the MSCI World Index, a broad measure of global equities, returned 15.90%; while the S&P 500^® Index, a broad measure of U.S. stocks, returned 18.40%; and the technology-laden Nasdaq Composite Index returned 44.92%. The MSCI EAFE Index of developed-market international equities returned 7.82%; while the MSCI Emerging Markets Index returned 18.31% during the period.

Fund Performance

For the 12-month period ended December 31, 2020, Eaton Vance Tax-Managed Global Buy-Write Opportunities Fund (the Fund) returned 8.55% at net asset value of its common shares (NAV), underperforming the 18.40% return of its primary benchmark, the S&P 500^® Index (the Index); but outperforming the 5.38% return of the MSCI Europe Index, the –2.75% return of the Cboe S&P 500 BuyWrite Index^SM and the 7.02% return of the Cboe NASDAQ-100 BuyWrite Index^SM.

The Fund’s options overlay strategy (the options strategy) was the largest single detractor from Fund performance versus the Index, as might be expected during a period of strong equity market performance. The Fund employs an options strategy of writing — that is, selling — stock index call options on a portion of its underlying common stock portfolio. The options strategy is designed to help limit the Fund’s exposure to market volatility and provide current income, but may limit the Fund’s upside potential in a rising market environment.

During the period, the overall market was characterized by significant levels of volatility, related to the precipitous decline in the first quarter of 2020 caused by the COVID-19 pandemic and the subsequent strong rebound in equity performance. Overall implied volatility — as measured by the Cboe Volatility Index, or “fear gauge” — was elevated for most of the period as market indexes repeatedly set new all-time highs. In this market environment, elevated option premiums were not able to offset the speed of the equity market rally. As a result, the options strategy — while it cushioned Fund performance during the short, sharp market downturn in the spring of 2020 — dragged on Fund performance versus the Index for the period as a whole. The options strategy was able to outperform the option benchmarks due to diversified strikes — or set prices at which derivative contracts may be bought or sold when exercised — and maturities when selecting options to sell.

The Fund’s common stock portfolio outperformed the Index and, thus, contributed to Fund performance versus the Index. On a country basis, the Fund’s allocation to U.S. equities — which averaged about 55% of the portfolio during the period — was the largest contributor to results versus the Index due to strong stock selections in the Fund’s U.S. holdings. The Fund’s allocations to Japanese and Netherlands stocks outperformed the U.S.-centric Index and, thus, contributed to performance relative to the Index as well. In contrast, the Fund’s allocation to the U.K. equity market was the largest detractor from relative returns on a country basis due, in part, to Brexit concerns that

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.

weighed on U.K. stocks for much of the period. The Fund’s holdings in French, Swiss, Italian, German, and Spanish equities underperformed the U.S.-centric Index and hurt performance versus the Index as well.

On a sector basis, contributors to performance versus the Index included stock selections in the communication services sector; underweight positions relative to the Index in the energy and real estate sectors, where demand declined significantly due to the global pandemic; and stock selections and an underweight position in the utilities sector. Detractors from relative performance included stock selections and an underweight position in the information technology sector; stock selections in the financials sector; and stock selections and an overweight position in the consumer staples sector during the period.

Average Market Cap: An indicator of the size of the companies in which the Fund invests and is the sum of each security’s weight in the portfolio multiplied by its market cap. Market Cap is determined by multiplying the price of a share of a company’s common stock by the number of shares outstanding.

Call Option: For an index call option, the buyer has the right to receive from the seller (or writer) a cash payment at the option expiration date equal to any positive difference between the value of the index at contract expiration and the exercise price. The buyer of a call option makes a cash payment (premium) to the seller (writer) of the option upon entering into the option contract.

Covered Call Strategy: A strategy of owning a portfolio of common stocks and writing call options on all or a portion of such stocks to generate current earnings from option premium.

In the Money: For a call option on an index, the extent to which the current price of the index exceeds the exercise price of the option.

Important Notice to Shareholders

On August 13, 2020, the Board of Trustees of the Fund amended and restated the Fund’s By-Laws (the “Amended and Restated By-Laws”). The Amended and Restated By-Laws include provisions (the “Control Share Provisions”) pursuant to which, in summary, a shareholder who obtains beneficial ownership of Fund shares in a “Control Share Acquisition” may exercise voting rights with respect to such shares only to the extent the authorization of such voting rights is approved by other shareholders of the Fund. The Control Share Provisions are primarily intended to protect the interests of the Fund and its shareholders by limiting the risk that the Fund will become subject to undue influence by opportunistic hedge funds or other activist investors. The Control Share Provisions do not eliminate voting rights for shares acquired in Control Share Acquisitions, but rather, they entrust the Fund’s other “non-interested” shareholders with determining whether to approve the authorization of voting rights for such shares. Subject to various conditions and exceptions, the Amended and Restated By-Laws define a “Control Share Acquisition” to include an acquisition of Fund shares that, but for the Control Share Provisions, would give the beneficial owner, upon the acquisition of such shares, the ability to exercise voting power in the election of Fund Trustees in any of the following ranges: (i) one-tenth or more,

but less than one-fifth of all voting power; (ii) one-fifth or more, but less than one-third of all voting power; (iii) one-third or more, but less than a majority of all voting power; or (iv) a majority or more of all voting power. Share acquisitions prior to August 13, 2020 are excluded from the definition of Control Share Acquisition. This discussion is only a high-level summary of certain aspects of the Control Share Provisions, and is qualified in its entirety by reference to the full Amended and Restated By-Laws. The Amended and Restated By-Laws were filed by the Fund on Form 8-K with the Securities and Exchange Commission and are available at sec.gov.

Notes to Financial Statements

1 Significant Accounting Policies

Eaton Vance Tax-Managed Global 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 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.

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. In consideration of recent decisions rendered by European courts, the Fund has filed additional tax reclaims for previously withheld taxes on dividends earned in certain European Union countries. These filings are subject to various administrative and judicial proceedings within these countries. Due to the uncertainty as to the ultimate resolution of these proceedings, the likelihood of receipt of these reclaims, and the potential timing of payment, no amounts are reflected in the financial statements for such outstanding reclaims.

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, 2020, 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 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.

Notes to Financial Statements — continued

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.

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, 2020 and December 31, 2019 was as follows:


	Year Ended December 31,
	2020		2019

Ordinary income	$	8,627,971	$	15,214,720

Long-term capital gains	$	46,845,472	$	9,585,441

Tax return of capital	$	38,295,995	$	68,948,455

As of December 31, 2020, the components of distributable earnings (accumulated loss) on a tax basis were as follows:



Post October capital losses	$	(16,237,700	)

Net unrealized appreciation	$	772,264,519

At December 31, 2020, the Fund had a net capital loss of $16,237,700 attributable to security transactions incurred after October 31, 2020 that it has elected to defer. This net capital loss is treated as arising on the first day of the Fund’s taxable year ending December 31, 2021.

Notes to Financial Statements — continued

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Fund at December 31, 2020, as determined on a federal income tax basis, were as follows:



Aggregate cost	$	329,461,802

Gross unrealized appreciation	$	775,583,941

Gross unrealized depreciation		(3,541,858	)

Net unrealized appreciation	$	772,042,083

3 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Eaton Vance Management (EVM), a wholly-owned subsidiary of Eaton Vance Corp., 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, 2020, the Fund’s investment adviser fee amounted to $10,252,292. Pursuant to a sub-advisory agreement, EVM has delegated a portion of the investment management to Parametric Portfolio Associates LLC (Parametric), a wholly-owned indirect 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.

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, 2020, 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 $75,925,017 and $262,719,522, respectively, for the year ended December 31, 2020.

5 Common Shares of Beneficial Interest and Shelf Offering

The Fund may issue common shares pursuant to its dividend reinvestment plan. Common shares issued by the Fund pursuant to its dividend reinvestment plan for the year ended December 31, 2020 were 26,037. There were no common shares issued by the Fund for the year ended December 31, 2019.

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 years ended December 31, 2020 and December 31, 2019.

Pursuant to a registration statement filed with and declared effective on April 12, 2018 by the SEC, the Fund is authorized to issue up to an additional 12,811,820 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 years ended December 31, 2020 and December 31, 2019, there were no common shares sold by the Fund pursuant to its shelf offering.

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, 2020 is included in the Portfolio of Investments. At December 31, 2020, 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 value 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, 2020 was as follows:


	Fair Value
Derivative	Asset Derivative		Liability Derivative⁽¹⁾

Written options	$	—	$	(18,524,989	)

⁽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, 2020 was as follows:


Derivative	Realized Gain (Loss) on Derivatives Recognized in Income⁽¹⁾			Change in Unrealized Appreciation (Depreciation) on Derivatives Recognized in Income⁽²⁾

Written options	$	(105,143,150	)	$	2,449,127

⁽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, 2020, which is indicative of the volume of this derivative type, was 8,449 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.

8 Risks and Uncertainties

Risks Associated with Foreign Investments

Investing in securities issued by companies whose principal business activities are outside the United States may involve significant risks not present in domestic investments. For example, there is generally less publicly available information about foreign companies, particularly those not subject to the disclosure and reporting requirements of the U.S. securities laws. Certain foreign issuers are generally not bound by uniform accounting, auditing, and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Investments in foreign securities also involve the risk of possible adverse changes in investment or exchange control regulations, expropriation or confiscatory taxation, limitation on the removal of funds or other assets of the Fund, political or financial instability or diplomatic and other developments which could affect such investments. Foreign securities markets, while growing in volume and sophistication, are generally not as developed as those in the United States, and securities of some foreign issuers (particularly those located in developing countries) may be less liquid and more volatile than securities of comparable U.S. companies. In general, there is less overall governmental supervision and regulation of foreign securities markets, broker/dealers and issuers than in the United States.

Pandemic Risk

An outbreak of respiratory disease caused by a novel coronavirus was first detected in China in December 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.

9 Legal Proceedings

In November 2010, the Fund was named as defendant and a putative member of the proposed defendant class of shareholders in the case entitled Official Committee of Unsecured Creditors (UCC) of the Tribune Company v. FitzSimons, et al. as a result of its ownership of shares in the Tribune Company

Notes to Financial Statements — continued

(Tribune) in 2007 when Tribune effected a leveraged buyout transaction (LBO) and was converted to a privately held company. The UCC, which has been replaced by a Litigation Trustee pursuant to Tribune’s plan of reorganization, seeks to recover payments of the proceeds of the LBO. In June 2011, a group of Tribune creditors filed multiple actions against former Tribune shareholders involving state law constructive fraudulent conveyance claims arising out of the LBO (the “SLFC actions”). The Fund has been named as a defendant in one of the SLFC actions filed in United States District Court — District of Massachusetts by Deutsche Bank Trust Co. Americas seeking to recover the proceeds received in connection with the LBO from former shareholders. The FitzSimons action and the SLFC actions are now part of a multi-district litigation proceeding in the Southern District of New York. The value of the proceeds received by the Fund is approximately $891,000 (equal to 0.08% of net assets at December 31, 2020). The Fund cannot predict the outcome of these proceedings or the effect, if any, on the Fund’s net asset value. The attorneys’ fees and costs related to these actions are expensed by the Fund as incurred.

10 Additional Information

On October 8, 2020, Morgan Stanley and Eaton Vance Corp. (“Eaton Vance”) announced that they had entered into a definitive agreement under which Morgan Stanley would acquire Eaton Vance. Under the Investment Company Act of 1940, as amended, consummation of this transaction may be deemed to result in the automatic termination of an Eaton Vance Fund’s investment advisory agreement and, where applicable, any related sub-advisory agreement. On November 10, 2020, the Fund’s Board approved a new investment advisory agreement and a new sub-advisory agreement. The new investment advisory agreement and new sub-advisory agreement were approved by Fund shareholders at a joint special meeting of shareholders held on January 22, 2021, and would take effect upon consummation of the transaction.

To the Trustees and Shareholders of Eaton Vance Tax-Managed Global 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 Global Buy-Write Opportunities Fund (the “Fund”), including the portfolio of investments, as of December 31, 2020, 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, 2020, 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, 2020, 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.

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.

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 Tax-Managed Global Buy-Write Opportunities Fund (“ETW”).

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 (the “New Investment Advisory Agreements”) and, for certain Funds, a new investment sub-advisory agreement between Eaton Vance and the applicable Sub-Adviser (the “New Investment Sub-Advisory Agreements”⁽²⁾ and, together with the New Investment Advisory Agreements, the “New Agreements”), 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, the Sub-Advisers, 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 Investment Advisory Agreement and, as applicable, New Investment Sub-Advisory Agreement, including the fees payable thereunder, was fair and reasonable, and it voted to approve the New Investment Advisory Agreement and, as applicable, New Investment Sub-Advisory 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, their respective affiliates, and, as applicable, the Sub-Advisers during meetings on November 5, 2020 and November 10, 2020.

The Contract Review Committee again met with senior representatives of Eaton Vance, the Sub-Advisers, and Morgan Stanley at its meeting on November 10, 2020, to further discuss the approval of the New Agreements. The representatives from Eaton Vance, the Sub-Advisers, and Morgan Stanley each made presentations to, and responded to questions from, the Independent Trustees. The Contract Review Committee considered Eaton Vance’s, the Sub-Adviser’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:

•

Confirmation that the current senior management team at Eaton Vance has indicated its strong support of the Transaction; and

•

Information regarding the fact that Morgan Stanley and Eaton Vance Corp. will each derive benefits from the Transaction and that, as a result, they have a financial interest in the matters that were being 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 and the Sub-Advisers 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, including the Sub-Advisers, 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 and, as applicable, the Sub-Advisers under the Current Agreements. In evaluating the nature, extent and quality of services to be provided by Eaton Vance and the Sub-Advisers 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 the Sub-Advisers, 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 and the Sub-Advisers, as applicable, 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, the Sub-Advisers, and existing Morgan Stanley affiliates and their respective personnel.

The Board considered Eaton Vance’s and the Sub-Advisers’ 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 and, as applicable, Sub-Advisers’ investment professionals in implementing each Fund’s investment strategies. The Board also took into account the resources dedicated to portfolio management and 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, including the Sub-Advisers. 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 and the Sub-Advisers, 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, the Sub-Advisers 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, including the Sub-Advisers, and that the Transaction was not expected to have an adverse effect on the ability of Eaton Vance and its affiliates, including the Sub-Advisers, to provide those services. The Board concluded that the nature, extent and quality of services expected to be provided by Eaton Vance and the Sub-Advisers, 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 and the Sub-Advisers 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 and the Sub-Advisers, as applicable, provide 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 and such Sub-Advisers as between each Fund and other types of accounts.

After considering the foregoing information, and in light of the nature, extent and quality of the services expected to be provided by Eaton Vance and the Sub-Advisers, 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, including the Sub-Advisers, 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, including the Sub-Advisers, 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, including the Sub-Advisers, 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 ETW) 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.

Audit Fees	$	57,450	$	57,450
Audit-Related Fees⁽¹⁾	$	0	$	0
Tax Fees⁽²⁾	$	11,066	$	9,756
All Other Fees⁽³⁾	$	0	$	0

Total	$	68,516	$	67,206

⁽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 and other related tax compliance/planning matters.

⁽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, 2019 and December 31, 2020; 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	12/31/19		12/31/20
Registrant	$	11,066	$	9,756
Eaton Vance⁽¹⁾	$	59,903	$	150,300

⁽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 7.

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

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

The Policies are designed to promote accountability of a company’s management to its shareholders and to align the interests of management with those shareholders. An independent proxy voting service (“Agent”), currently Institutional Shareholder Services, Inc., has been retained to assist in the voting of proxies through the

provision of vote analysis, implementation and recordkeeping and disclosure services. The investment adviser will generally vote proxies through the Agent. The Agent is required to vote all proxies in accordance with customized proxy voting guidelines (the “Guidelines”) and/or refer them back to the investment adviser pursuant to the Policies.

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

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

The investment adviser’s Global Proxy Group is responsible for monitoring and resolving possible material conflicts with respect to proxy voting. Because the Guidelines are predetermined and designed to be in the best interests of shareholders, application of the Guidelines to vote client proxies should, in most cases, adequately address any possible conflict of interest. The investment adviser will monitor situations that may result in a conflict of interest between any of its clients and the investment adviser or any of its affiliates by maintaining a list of significant existing and prospective corporate clients. The Proxy Administrator will compare such list with the names of companies of which he or she has been referred a proxy statement (the “Proxy Companies”). If a company on the list is also a Proxy Company, the Proxy Administrator will report that fact to the Global Proxy Group. If the Proxy Administrator intends to instruct the Agent to vote in a manner inconsistent with the Guidelines, the Global Proxy Group will first determine, in consultation with legal counsel if necessary, whether a material conflict exists. If it is determined that a material conflict exists, the investment adviser will seek instruction on how the proxy should be voted from the Fund’s Board, or any committee or subcommittee identified by the Board. If a matter is referred to the Global Proxy Group, the decision made and basis for the decision will be documented by the Proxy Administrator and/or Global Proxy Group.

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

Item 8.

Portfolio Managers of Closed-End Management Investment Companies

Eaton Vance Management (“EVM” or “Eaton Vance”) is the investment adviser of the Fund. 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 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⁽¹⁾
Registered Investment Companies		17	$	44,469.2			0	$	0
Other Pooled Investment Vehicles		14	$	31,114.2	⁽²⁾		0	$	0
Other Accounts		1	$	0.5			0	$	0

Thomas C. Seto
Registered Investment Companies		44	$	28,222.4	⁽³⁾		0	$	0
Other Pooled Investment Vehicles		8	$	1,937.6			0	$	0
Other Accounts		47,478	$	155,834.2	⁽⁴⁾		0	$	0

⁽¹⁾

This portfolio manager serves as portfolio manager of one or more registered investment companies that invests or may invest in one or more underlying registered investment companies in the Eaton Vance family of funds or other pooled investment vehicles sponsored by Eaton Vance. The underlying investment companies may be managed by this portfolio manager or another portfolio manager.

⁽²⁾

Certain of these “Other Pooled Investment Vehicles” invest a substantial portion of their assets either in a registered investment company in the Eaton Vance family of funds and/or in a separate pooled investment vehicle sponsored by Eaton Vance which may be managed by this portfolio manager or another portfolio manager.

⁽³⁾	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.

⁽⁴⁾	For “Other Accounts” that are part of a wrap or model 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 or model 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 based on the performance of the securities held by that account. The existence of such a performance based fee may create additional conflicts of interest for the portfolio manager in the allocation of management time, resources and investment opportunities. Whenever conflicts of interest arise, the portfolio manager will endeavor to exercise his discretion in a manner that he believes is equitable to all interested persons. EVM has adopted several policies and procedures designed to address these potential conflicts including a code of ethics and policies that govern the investment adviser’s trading practices, including among other things the aggregation and allocation of trades among clients, brokerage allocations, cross trades and best execution.

Compensation Structure for EVM

Compensation of EVM’s portfolio managers and other investment professionals has the following primary components: (1) a base salary, (2) an annual cash bonus, and (3) annual non-cash compensation consisting of restricted shares of EVC nonvoting common stock that generally are subject to a vesting schedule. 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 Sharpe ratio, which 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. 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) an annual cash bonus, and (3) annual equity-based compensation awards that generally are subject to a multi-year vesting schedule. Stock-based compensation awards and adjustments in base salary and bonuses are typically paid and/or put into effect at or shortly after, the firm’s fiscal year-end, October 31.

Method to Determine Compensation. Parametric seeks to compensate portfolio managers commensurate with their responsibilities and performance while remaining competitive with other firms within the investment management industry. In the case of investment strategies that are systematic, including the Fund’s, portfolio managers primarily are measured with respect to whether a strategy’s rules as implemented delivered on the strategy’s objectives. In evaluating the foregoing, Parametric evaluates the manner in which the strategy is implemented relative to strategy targets, rebalancing portfolio exposures consistent with pre-determined triggers, and judicious trade construction. Portfolio managers are also expected to monitor factors that may impact implementation of a strategy and to seek potential ways to address them as needed.

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

Parametric participates in compensation surveys that benchmark salaries, total cash and total compensation against other firms in the industry. This data is reviewed, along with a number of other factors, to ensure that compensation remains competitive with other firms in the industry.

Dear Eaton Vance Fund Shareholder:

This notice provides shareholders of the Eaton Vance Tax-Managed Global Buy-Write Opportunities Fund (NYSE: ETW) with important information concerning the distribution declared in July 2020. You are receiving this notice as a requirement of the Fund’s managed distribution plan (Plan). The Board of Trustees approved the implementation of the Plan to make monthly cash distributions to common shareholders, stated in terms of a fixed amount per common share. This information is sent to you for informational purposes only and is an estimate of the sources of the July distribution. It is not determinative of the tax character of the Fund’s distributions for the 2020 calendar year.

The amounts and sources of distributions reported in this notice are estimates, are not being provided for tax reporting purposes and the distribution may later be determined to be from other sources including realized short-term gains, long-term gains, to the extent permitted by law, and return of capital. The actual amounts and sources for tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Distribution Period: July 2020

Distribution Amount per Common Share: $0.0727

The following table sets forth an estimate of the sources of the Fund’s July distribution and its cumulative distributions paid this fiscal year to date. Amounts are expressed on a per common share basis and as a percentage of the distribution amount.

IMPORTANT DISCLOSURE: You should not draw any conclusions about the Fund’s investment performance from the amount of this distribution or from the terms of the Fund’s Plan. The Fund estimates that it has distributed more than its income and net realized capital gains; therefore, a portion of your distribution may be a return of capital. A return of capital may occur for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with ‘yield’ or ‘income.’ The amounts and sources of distributions reported in this Notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for accounting and/or tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Set forth in the table below is information relating to the Fund’s performance based on its net asset value (NAV) for certain periods.


Average annual total return at NAV for the 5-year period ended on June 30, 2020¹	4.22	%
Annualized current distribution rate expressed as a percentage of NAV as of June 30, 2020²	9.44	%
Cumulative total return at NAV for the fiscal year through June 30, 2020³	-7.18	%
Cumulative fiscal year to date distribution rate as a percentage of NAV as of June 30, 2020⁴	4.72	%

¹	Average annual total return at NAV represents the change in NAV of the Fund, with all distributions reinvested, for the 5-year period ended on June 30, 2020.

²	The annualized current distribution rate is the cumulative distribution rate annualized as a percentage of the Fund’s NAV as of June 30, 2020.

³	Cumulative total return at NAV is the percentage change in the Fund’s NAV for the period from the beginning of its fiscal year to June 30, 2020 including distributions paid and assuming reinvestment of those distributions.

⁴	Cumulative fiscal year distribution rate for the period from the beginning of its fiscal year to June 30, 2020 measured on the dollar value of distributions in the year-to-date period as a percentage of the Fund’s NAV as of June 30, 2020.
