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 investment adviser has claimed an exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of the Fund. Accordingly, neither the Fund nor the adviser with respect to the operation of the Fund is subject to CFTC regulation. Because of its management of other strategies, the Fund’s adviser is registered with the CFTC as a commodity pool operator. The adviser is also registered as a commodity trading advisor.

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.

This report must be preceded or accompanied by a current summary prospectus or prospectus. Before investing, investors should consider carefully the investment objective, risks, and charges and expenses of a mutual fund. This and other important information is contained in the summary prospectus and prospectus, which can be obtained from a financial intermediary. Prospective investors should read the prospectus carefully before investing. For further information, please call 1-800-262-1122.

Management’s Discussion of Fund Performance¹

Economic and Market Conditions

As the 12-month period opened on October 1, 2019, interest rates were trending modestly upward amid better-than-expected U.S. employment reports and cautious optimism about a détente in U.S.-China trade relations. Interest rates continued to move upward through the end of 2019.

In January 2020, however, news of the novel coronavirus outbreak in China began to raise investor concerns and led to a “flight to quality” that sparked a brief fixed-income market rally. As the virus turned into a global pandemic in February and March, it ended the longest-ever period of U.S. economic expansion and brought about a global economic slowdown. Credit markets along with equity markets declined in value amid unprecedented volatility.

In response, the U.S. Federal Reserve (the Fed) 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 credit markets. At its July meeting, the Fed provided additional reassurances that it would maintain rates close to zero percent for the foreseeable future and use all tools at its disposal to support the U.S. economy. These moves helped calm the markets and initiated a new fixed-income rally that began in April and lasted through most of the summer.

Midway through August, however, the fixed-income rally stalled as investors grew concerned about a resurgence of the coronavirus and the consequences for the nascent economic recovery. For the rest of the period, fixed-income prices were flat to down, driven in part by Congress’ failure to pass another stimulus bill — following the expiration of support from the federal CARES Act passed in March 2020, which boosted unemployment benefits and helped businesses keep workers employed. As the period ended, the U.S. Senate and House were deadlocked on an additional stimulus bill, and coronavirus cases were rising.

For the period as a whole, most fixed-income asset classes delivered positive returns, with strong gains from April through mid-August 2020, which compensated for losses in March. The Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of the U.S. bond market, returned 6.98% for the period. As corporate bonds benefited from Fed policy — which included purchases of corporate investment-grade debt and high yield exchange-traded funds — the Bloomberg Barclays U.S. Corporate Bond Index returned 7.90% for the period.

High yield bonds, which had fared poorly early in the period, outperformed investment-grade bonds in the second half of the period as investors searched for yield in a low-rate environment. For the period as a whole, the Bloomberg Barclays U.S. Corporate High Yield Index returned 3.25%.

Fund Performance

For the 12-month period ended September 30, 2020, Eaton Vance Core Plus Bond Fund (the Fund) returned 2.21% for Class A shares at net asset value (NAV), underperforming its benchmark, the Bloomberg Barclays U.S. Aggregate Bond Index (the Index), which returned 6.98%.

The Fund’s underperformance versus the Index was driven largely by security selection in commercial mortgage-backed securities (CMBS) and asset-backed securities (ABS); security selection and an overweight allocation, relative to the Index, in dollar-denominated emerging market (EM) debt; a lack of mortgage-backed securities (MBS) holdings, an Index sector that performed well; and an underweight allocation to U.S. Treasurys.

With regard to CMBS, the Fund’s holdings in retail and office building CMBS declined during the period, as many retail businesses closed or delayed mortgage and rent payments, and demand for office space fell due to employees working from home. The Fund’s overweight allocation to ABS, which are generally highly rated and backed largely by consumer debt, delivered positive performance, but underperformed the Index. The

Fund’s holdings in dollar-denominated EM debt underperformed the Index due to the Fund’s holdings in weak-performing sectors, including transportation and finance.

The Fund’s lack of exposure to MBS, which comprised about 26% of the Index during the period, detracted from performance versus the Index as well. The implicit U.S. government guarantee inherent in MBS — because most are issued by the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) — made them a beneficiary of investors’ preference for higher quality assets during the period’s market turmoil. Similarly, U.S. Treasurys were one of the best-performing fixed-income asset classes in a period when investors favored assets perceived as less risky, and the Fund’s underweight allocation hurt Index-relative results.

In contrast, the Fund’s allocations to three out-of-Index asset classes that performed well — convertible bonds, collateralized mortgage obligations (CMOs), and high yield bonds — contributed to performance versus the Index. The Fund’s holdings in CMOs, which are sensitive to interest rate changes, performed well during the period. The Fund purchased CMOs when the housing market was experiencing extreme uncertainty, and those securities rose in price as interest rates declined and the housing market recovered during the period.

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 offering price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when redeemed, 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.

¹  The views expressed in this report are those of the portfolio manager(s) and are current only through the date stated at the top of this page. These views are subject to change at any time based upon market or other conditions, and Eaton Vance and the Fund(s) disclaim any responsibility to update such views. These views may not be relied upon as investment advice and, because investment decisions are based on many factors, may not be relied upon as an indication of trading intent on behalf of any Eaton Vance fund. This commentary may contain statements that are not historical facts, referred to as “forward-looking statements.” The Fund’s actual future results may differ significantly from those stated in any forward-looking statement, depending on factors such as changes in securities or financial markets or general economic conditions, the volume of sales and purchases of Fund shares, the continuation of investment advisory, administrative and service contracts, and other risks discussed from time to time in the Fund’s filings with the Securities and Exchange Commission.

²  Bloomberg Barclays U.S. Aggregate Bond Index is an unmanaged index of domestic investment-grade bonds, including corporate, government and mortgage-backed securities. Unless otherwise stated, index returns do not reflect the effect of any applicable sales charges, commissions, expenses, taxes or leverage, as applicable. It is not possible to invest directly in an index.

³  Total Returns at NAV do not include applicable sales charges. If sales charges were deducted, the returns would be lower. Total Returns shown with maximum sales charge reflect the stated maximum sales charge. Unless otherwise stated, performance does not reflect the deduction of taxes on Fund distributions or redemptions of Fund shares.

Effective May 1, 2015, the Fund changed its investment objective and policies. Prior to May 1, 2015, the Fund invested primarily in Build America Bonds. Performance prior to May 1, 2015 reflects the Fund’s performance under its former investment objective and policies.

⁴  Source: Fund prospectus. Net expense ratios reflect a contractual expense reimbursement that continues through 1/31/21. Without the reimbursement, performance would have been lower. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report.

⁵  Ratings are based on Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings (“S&P”) or Fitch Ratings (“Fitch”), as applicable. If securities are rated differently by the ratings agencies, the highest rating is applied. Ratings, which are subject to change, apply to the creditworthiness of the issuers of the underlying securities and not to the Fund or its shares. Credit ratings measure the quality of a bond based on the issuer’s creditworthiness, with ratings ranging from AAA, being the highest, to D, being the lowest based on S&P’s measures. Ratings of BBB or higher by S&P or Fitch (Baa or higher by Moody’s) are considered to be investment-grade quality. Credit ratings are based largely on the ratings agency’s analysis at the time of rating. The rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition and does not necessarily reflect its assessment of the volatility of a security’s market value or of the liquidity of an investment in the security. Holdings designated as “Not Rated” (if any) are not rated by the national ratings agencies stated above.

⁶  Other, if any, represents any investment type less than 1% of total investments.

Fund profile subject to change due to active management.

Additional Information

Bloomberg Barclays U.S. Corporate Bond Index measures the performance of investment-grade U.S. corporate securities with a maturity of one year or more. Bloomberg Barclays U.S. Corporate High Yield Index measures USD-denominated, non-investment grade corporate securities.

Duration is a measure of the expected change in price of a bond — in percentage terms — given a one percent change in interest rates, all else being constant. Securities with lower durations tend to be less sensitive to interest rate changes.

Fund Expenses

Example:  As a Fund shareholder, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchases and redemption fees (if applicable); and (2) ongoing costs, including management fees; distribution and/or service fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of Fund investing and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (April 1, 2020 – September 30, 2020).

Actual Expenses:  The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes:  The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the actual Fund expense ratio and an assumed rate of return of 5% per year (before expenses), which is not the actual Fund return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption fees (if applicable). Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would be higher.

	Beginning Account Value (4/1/20)		Ending Account Value (9/30/20)		Expenses Paid During Period* (4/1/20 – 9/30/20)			Annualized Expense Ratio
Actual
Class A	$	1,000.00	$	1,126.20	$	3.93	**		0.74	%
Class C	$	1,000.00	$	1,123.10	$	7.91	**		1.49	%
Class I	$	1,000.00	$	1,127.70	$	2.61	**		0.49	%
Hypothetical
(5% return per year before expenses)
Class A	$	1,000.00	$	1,021.30	$	3.74	**		0.74	%
Class C	$	1,000.00	$	1,017.60	$	7.52	**		1.49	%
Class I	$	1,000.00	$	1,022.60	$	2.48	**		0.49	%

* Expenses are equal to the Fund’s annualized expense ratio for the indicated Class, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period). The Example assumes that the $1,000 was invested at the net asset value per share determined at the close of business on March 31, 2020.

** Absent an allocation of certain expenses to an affiliate, expenses would be higher.

⁽⁸⁾ Security exempt from registration under Regulation S of the Securities Act of 1933, as amended, which exempts from registration securities offered and sold outside the United States. Security may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act of 1933, as amended. At September 30, 2020, the aggregate value of these securities is $6,033,565 or 0.8% of the Fund’s net assets.

⁽⁹⁾ Senior floating-rate loans (Senior Loans) often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. However, Senior Loans will typically have an expected average life of approximately two to four years. Senior Loans typically have rates of interest which are redetermined periodically by reference to a base lending rate, plus a spread. These base lending rates are primarily the London Interbank Offered Rate (“LIBOR”) and secondarily, the prime rate offered by one or more major United States banks (the “Prime Rate”). Base lending rates may be subject to a floor, or minimum rate. Senior Loans are generally subject to contractual restrictions that must be satisfied before they can be bought or sold.

⁽¹⁰⁾  For fair value measurement disclosure purposes, security is categorized as Level 3 (see Note 11).

⁽¹¹⁾  Non-income producing security.

⁽¹²⁾ Inflation-linked security whose principal is adjusted for inflation based on changes in the U.S. Consumer Price Index. Interest is calculated based on the inflation-adjusted principal.

⁽¹³⁾  Affiliated investment company, available to Eaton Vance portfolios and funds, which invests in high quality, U.S. dollar denominated money market instruments. The rate shown is the annualized seven-day yield as of September 30, 2020.

1  Significant Accounting Policies

Eaton Vance Core Plus Bond Fund (the Fund) is a diversified series of Eaton Vance Mutual Funds Trust (the Trust). The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The Fund’s investment objective is total return. The Fund offers three classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. Class C shares are sold at net asset value and are generally subject to a contingent deferred sales charge (see Note 5). Effective January 25, 2019, Class C shares generally automatically convert to Class A shares ten years after their purchase and, effective November 5, 2020, automatically convert to Class A shares eight years after their purchase as described in the Fund’s prospectus. Class I shares are sold at net asset value and are not subject to a sales charge. Each class represents a pro-rata interest in the Fund, but votes separately on class-specific matters and (as noted below) is subject to different expenses. Realized and unrealized gains and losses are allocated daily to each class of shares based on the relative net assets of each class to the total net assets of the Fund. Net investment income, other than class-specific expenses, is allocated daily to each class of shares based upon the ratio of the value of each class’s paid shares to the total value of all paid shares. Each class of shares differs in its distribution plan and certain other class-specific expenses.

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.

Debt Obligations. Debt obligations are generally valued on the basis of valuations provided by third party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and ask prices, broker/dealer quotations, prices or yields of securities with similar characteristics, interest rates, anticipated prepayments, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. Short-term debt obligations purchased with a remaining maturity of sixty days or less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value.

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 or, in the case of preferred equity securities that are not listed or traded in the over-the-counter market, by a third party pricing service that uses various techniques that consider factors including, but not limited to, prices or yields of securities with similar characteristics, benchmark yields, broker/dealer quotes, quotes of underlying common stock, issuer spreads, as well as industry and economic events.

Senior Floating-Rate Loans. Interests in senior floating-rate loans (Senior Loans) for which reliable market quotations are readily available are valued generally at the average mean of bid and ask quotations obtained from a third party pricing service.

Derivatives. Financial futures contracts are valued at the closing settlement price established by the board of trade or exchange on which they are traded. Forward foreign currency exchange contracts are generally valued at the mean of the average bid and average ask prices that are reported by currency dealers to a third party pricing service at the valuation time. Such third party pricing service valuations are supplied for specific settlement periods and the Fund’s forward foreign currency exchange contracts are valued at an interpolated rate between the closest preceding and subsequent settlement period reported by the third party pricing service.

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.

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

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

Notes to Financial Statements — continued

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 — Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount. Fees associated with loan amendments are recognized immediately. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. Withholding taxes on foreign interest and dividends have been provided for in accordance with the Fund’s understanding of the applicable countries’ tax rules and rates. Inflation adjustments to the principal amount of inflation-adjusted bonds and notes are reflected as interest income. Deflation adjustments to the principal amount of an inflation-adjusted bond or note are reflected as reductions to interest income to the extent of interest income previously recorded on such bond or note.

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.

In addition to the requirements of the Internal Revenue Code, the Fund may also be subject to local taxes on the recognition of capital gains in certain countries. In determining the daily net asset value, the Fund estimates the accrual for such taxes, if any, based on the unrealized appreciation on certain portfolio securities and the related tax rates. Taxes attributable to unrealized appreciation are included in the change in unrealized appreciation (depreciation) on investments. Capital gains taxes on securities sold are included in net realized gain (loss) on investments.

As of September 30, 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  Expenses — The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated taking into consideration, among other things, the nature and type of expense and the relative size of the funds.

F  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.

G  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.

H  Indemnifications — Under the Trust’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 Trust) could be deemed to have personal liability for the obligations of the Trust. However, the Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and the By-laws provide that the Trust 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.

I  Financial Futures Contracts — Upon entering into a financial futures contract, the Fund is required to deposit with the broker, either in cash or securities, an amount equal to a certain percentage of the contract amount (initial margin). Subsequent payments, known as variation margin, are made or received by the Fund each business day, depending on the daily fluctuations in the value of the underlying security, and are recorded as unrealized gains or losses by the Fund. Gains (losses) are realized upon the expiration or closing of the financial futures contracts. Should market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. Futures contracts have minimal counterparty risk as they are exchange traded and the clearinghouse for the exchange is substituted as the counterparty, guaranteeing counterparty performance.

J  Forward Foreign Currency Exchange Contracts — The Fund may enter into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until such time as the contracts have been closed. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from movements in the value of a foreign currency relative to the U.S. dollar.

K  When-Issued Securities and Delayed Delivery Transactions — The Fund may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. At the time the transaction is negotiated, the price of the security that will be delivered is fixed. The Fund maintains cash and/or security positions for these commitments such that sufficient liquid assets will be

22

Eaton Vance

Core Plus Bond Fund

Notes to Financial Statements — continued

available to make payments upon settlement. Securities purchased on a delayed delivery or when-issued basis are marked-to-market daily and begin earning interest on settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

2  Distributions to Shareholders and Income Tax Information

The Fund declares dividends daily to shareholders of record at the time of declaration. Distributions are generally paid monthly. Distributions of realized capital gains are made at least annually. Distributions to shareholders are recorded on the ex-dividend date. Distributions are declared separately for each class of shares. Shareholders may reinvest income and capital gain distributions in additional shares of the same class of the Fund at the net asset value as of the ex-dividend date or, at the election of the shareholder, receive distributions in cash. 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.

The tax character of distributions declared for the years ended September 30, 2020 and September 30, 2019 was as follows:

	Year Ended September 30,
	2020		2019
Ordinary income	$	32,401,832	$	16,808,031

During the year ended September 30, 2020, accumulated loss was increased by $215,887 and paid-in capital was increased by $215,887 due to the Fund’s use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder’s portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2020, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

Undistributed long-term capital gains	$	1,965,763
Post October capital losses	$	(4,553,780	)
Late year ordinary losses	$	(526,113	)
Net unrealized depreciation	$	(16,515,515	)
Distributions payable	$	(9,044	)

At September 30, 2020, the Fund had a net capital loss of $4,553,780 attributable to security transactions incurred after October 31, 2019 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 September 30, 2021.

Additionally, at September 30, 2020, the Fund had a late year ordinary loss of $526,113 which it has elected to defer to the following taxable year pursuant to income tax regulations. Late year ordinary losses represent certain specified losses realized in that portion of a taxable year after October 31 that are treated as ordinary for tax purposes plus ordinary losses attributable to that portion of a taxable year after December 31.

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Fund at September 30, 2020, as determined on a federal income tax basis, were as follows:

Aggregate cost	$	726,543,361
Gross unrealized appreciation	$	19,924,468
Gross unrealized depreciation		(36,426,662	)
Net unrealized depreciation	$	(16,502,194	)

3  Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Boston Management and Research (BMR), a subsidiary of EVM and an indirect subsidiary of Eaton Vance Corp., as compensation for investment advisory services rendered to the Fund. Pursuant to the investment advisory agreement and subsequent fee reduction agreement between the Fund and BMR, the fee is computed at an annual rate of 0.45% of the Fund’s average daily net assets up to $1 billion and is

23

Eaton Vance

Core Plus Bond Fund

September 30, 2020

Notes to Financial Statements — continued

payable monthly. On net assets of $1 billion and over, the annual fee is reduced. The fee reduction cannot be terminated without the consent of the Trustees and shareholders. For the year ended September 30, 2020, the Fund’s investment adviser fee amounted to $3,887,627 or 0.45% of the Fund’s average daily net assets. The Fund invests its cash in Cash Reserves Fund. EVM does not currently receive a fee for advisory services provided to Cash Reserves Fund.

BMR has agreed to reimburse the Fund’s expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only) exceed 0.74%, 1.49% and 0.49% of the Fund’s average daily net assets for Class A, Class C and Class I, respectively. This agreement may be changed or terminated after January 31, 2021. Pursuant to this agreement, BMR was allocated $914,506 of the Fund’s operating expenses for the year ended September 30, 2020.

EVM serves as the administrator of the Fund, but receives no compensation. EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the year ended September 30, 2020, EVM earned $7,726 from the Fund pursuant to such agreement, which is included in transfer and dividend disbursing agent fees on the Statement of Operations. The Fund was informed that Eaton Vance Distributors, Inc. (EVD), an affiliate of EVM and the Fund’s principal underwriter, received $32,007 as its portion of the sales charge on sales of Class A shares for the year ended September 30, 2020. EVD also received distribution and service fees from Class A and Class C shares (see Note 4) and contingent deferred sales charges (see Note 5).

During the year ended September 30, 2020, BMR reimbursed the Fund $9,380 for a net realized loss due to a trading error. The impact of the reimbursement was less than $0.01 per share for each class and had no significant impact on total return.

Trustees and officers of the Fund who are members of EVM’s or BMR’s organizations receive remuneration for their services to the Fund out of the investment adviser fee. Trustees of the Fund who are not affiliated with the investment adviser 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 September 30, 2020, no significant amounts have been deferred. Certain officers and Trustees of the Fund are officers of the above organizations.

4  Distribution Plans

The Fund has in effect a distribution plan for Class A shares (Class A Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Fund pays EVD a distribution and service fee of 0.25% per annum of its average daily net assets attributable to Class A shares for distribution services and facilities provided to the Fund by EVD, as well as for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued to EVD for the year ended September 30, 2020 amounted to $384,931 for Class A shares.

The Fund also has in effect a distribution plan for Class C shares (Class C Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class C Plan, the Fund pays EVD amounts equal to 0.75% per annum of its average daily net assets attributable to Class C shares for providing ongoing distribution services and facilities to the Fund. For the year ended September 30, 2020, the Fund paid or accrued to EVD $440,144 for Class C shares.

Pursuant to the Class C Plan, the Fund also makes payments of service fees to EVD, financial intermediaries and other persons in amounts equal to 0.25% per annum of its average daily net assets attributable to that class. Service fees paid or accrued are for personal services and/or the maintenance of shareholder accounts. They are separate and distinct from the sales commissions and distribution fees payable to EVD. Service fees paid or accrued for the year ended September 30, 2020 amounted to $146,715 for Class C shares.

Distribution and service fees are subject to the limitations contained in the Financial Industry Regulatory Authority Rule 2341(d).

5  Contingent Deferred Sales Charges

A contingent deferred sales charge (CDSC) of 1% generally is imposed on redemptions of Class C shares made within 12 months of purchase. Class A shares may be subject to a 1% CDSC if redeemed within 18 months of purchase (depending on the circumstances of purchase). Generally, the CDSC is based upon the lower of the net asset value at date of redemption or date of purchase. No charge is levied on shares acquired by reinvestment of dividends or capital gain distributions. For the year ended September 30, 2020, the Fund was informed that EVD received approximately $17,000 and $14,000 of CDSCs paid by Class A and Class C shareholders, respectively.

6  Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, and including maturities, paydowns and principal repayments on Senior Loans, for the year ended September 30, 2020 were as follows:

	Purchases		Sales
Investments (non-U.S. Government)	$	613,571,086	$	607,370,173

The Fund’s Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest (without par value). Such shares may be issued in a number of different series (such as the Fund) and classes. Transactions in Fund shares were as follows:

	Year Ended September 30,
Class A	2020			2019

Redemptions		(47,985,690	)		(9,455,127	)
Net increase (decrease)		(6,989,763	)		38,774,888

8  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 financial futures contracts and forward foreign currency exchange contracts 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 September 30, 2020 is included in the Portfolio of Investments. At September 30, 2020, the Fund had sufficient cash and/or securities to cover commitments under these contracts.

In the normal course of pursuing its investment objective, the Fund is subject to the following risks:

Interest Rate Risk: The Fund enters into interest rate futures contracts to seek to hedge against fluctuations in interest rates and/or to change the effective duration of its portfolio.

Foreign Exchange Risk: The Fund engages in forward foreign currency exchange contracts to enhance total return, to seek to hedge against fluctuations in currency exchange rates and/or as a substitute for the purchase or sale of securities or currencies.

The Fund enters into forward foreign currency exchange contracts that may contain provisions whereby the counterparty may terminate the contract under certain conditions, including but not limited to a decline in the Fund’s net assets below a certain level over a certain period of time, which would trigger a

25

Core Plus Bond Fund

payment by the Fund for those derivatives in a liability position. At September 30, 2020, the fair value of derivatives with credit-related contingent features in a net liability position was $24,116. At September 30, 2020, there were no assets pledged by the Fund for such liability.

The over-the-counter (OTC) derivatives in which the Fund invests are subject to the risk that the counterparty to the contract fails to perform its obligations under the contract. To mitigate this risk, the Fund has entered into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement with its substantially all its derivative counterparties. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs certain OTC derivatives and typically contains, among other things, set-off provisions in the event of a default and/or termination event as defined under the relevant ISDA Master Agreement. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy or insolvency. Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Fund’s net assets decline by a stated percentage or the Fund fails to meet the terms of its ISDA Master Agreements, which would cause the counterparty to accelerate payment by the Fund of any net liability owed to it.

The collateral requirements for derivatives traded under an ISDA Master Agreement are governed by a Credit Support Annex to the ISDA Master Agreement. Collateral requirements are determined at the close of business each day and are typically based on changes in market values for each transaction under an ISDA Master Agreement and netted into one amount for such agreement. Generally, the amount of collateral due from or to a counterparty is subject to a minimum transfer threshold amount before a transfer is required, which may vary by counterparty. Collateral pledged for the benefit of the Fund and/or counterparty is held in segregated accounts by the Fund’s custodian and cannot be sold, re-pledged, assigned or otherwise used while pledged. The portion of such collateral representing cash, if any, is reflected as deposits for derivatives collateral and, in the case of cash pledged by a counterparty for the benefit of the Fund, a corresponding liability on the Statement of Assets and Liabilities. Securities pledged by the Fund as collateral, if any, are identified as such in the Portfolio of Investments.

The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure at September 30, 2020 was as follows:

		Fair Value
Risk	Derivative	Asset Derivative			Liability Derivative
Interest Rate	Futures contracts	$	—		$	(251,105	)(1)
Foreign Exchange	Forward foreign currency exchange contracts		57,932	(2)		(24,116	)(3)
Total		$	57,932		$	(275,221	)
Derivatives not subject to master netting or similar agreements		$	—		$	(251,105	)
Total Derivatives subject to master netting or similar agreements		$	57,932		$	(24,116	)

The average notional cost of futures contracts and average notional amounts of other derivative contracts outstanding during the year ended September 30, 2020, which are indicative of the volume of these derivative types, were approximately as follows:

Futures Contracts — Long		Futures Contracts — Short		Forward Foreign Currency Exchange Contracts*
	$111,029,000	$	17,486,000	$	4,931,000

* The average notional amount of forward foreign currency exchange contracts is based on the absolute value of notional amounts of currency purchased and currency sold.

9  Line of Credit

The Fund participates with other portfolios and funds managed by EVM and its affiliates in an $800 million unsecured line of credit agreement with a group of banks, which is in effect through October 27, 2020. In connection with the renewal of the agreement on October 29, 2019, funds managed by Calvert Research and Management, an affiliate of EVM, were added as participating funds to the agreement and the borrowing limit was increased from $625 million. Borrowings are made by the Fund solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Fund based on its borrowings at an amount above either the Eurodollar rate or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. Because the line of credit is not available exclusively to the Fund, it may be unable to borrow some or all of its requested amounts at any particular time. The Fund did not have any significant borrowings or allocated fees during the year ended September 30, 2020. Effective October 27, 2020, the Fund renewed its line of credit agreement, which expires October 26, 2021, at substantially the same terms.

10  Investments in Affiliated Funds

At September 30, 2020, the value of the Fund’s investment in affiliated funds was $18,277,199, which represents 2.5% of the Fund’s net assets. Transactions in affiliated funds by the Fund for the year ended September 30, 2020 were as follows:

11  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.

At September 30, 2020, 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
Corporate Bonds & Notes	$	—		$	304,191,263		$	—	$	304,191,263
Collateralized Mortgage Obligations		—			36,162,883			—		36,162,883

Asset-Backed Securities		—			144,457,942			—		144,457,942
Foreign Government Bonds		—			24,284,175			—		24,284,175
Senior Floating-Rate Loans		—			1,381,339			—		1,381,339

12  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.

13  Subsequent Event

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 result in the automatic termination of the Fund’s investment advisory agreement, and any related sub-advisory agreement(s), if applicable. Thus, the Fund’s Board will be asked to approve a new investment advisory agreement (and new sub-advisory agreement(s), if applicable). If approved by the Fund’s Board, the new investment advisory agreement (and new sub-advisory agreement(s), if applicable) is expected to be presented to Fund shareholders for approval, and, if approved, would take effect upon the closing of the transaction.

Report of Independent Registered Public Accounting Firm

To the Trustees of Eaton Vance Mutual Funds Trust and Shareholders of Eaton Vance Core Plus Bond Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Eaton Vance Core Plus Bond Fund (the “Fund”) (one of the funds constituting Eaton Vance Mutual Funds Trust), including the portfolio of investments, as of September 30, 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 September 30, 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 September 30, 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.

Board of Trustees’ Contract Approval

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended (the “1940 Act”), provides, in substance, that the investment advisory agreement between a fund and its investment adviser will continue in effect from year-to-year only if its continuation is approved on an annual basis by a vote of the fund’s board of trustees, including a majority of the trustees who are not “interested persons” of the fund (“independent trustees”), cast in person at a meeting called for the purpose of considering such approval.

At a meeting held on April 22, 2020 (the “April 2020 Meeting”), the Boards of Trustees/Directors comprised of the same individuals (collectively, the “Board”) that oversees a majority of the registered investment companies advised by Eaton Vance Management or its affiliate, Boston Management and Research (the “Eaton Vance Funds”), including a majority of the independent trustees (the “Independent Trustees”), voted to approve the continuation of existing investment advisory agreements and sub-advisory agreements⁽¹⁾ for each of the Eaton Vance Funds for an additional one-year period. The Board relied upon the affirmative recommendation of its Contract Review Committee, which is a committee exclusively comprised of Independent Trustees. Prior to making its recommendation, the Contract Review Committee reviewed information furnished by the adviser and sub-adviser to each of the Eaton Vance Funds (including information specifically requested by the Board) for a series of formal meetings held between February and April 2020. Members of the Contract Review Committee also considered information received at prior meetings of the Board and its committees, to the extent such information was relevant to the Contract Review Committee’s annual evaluation of the investment advisory agreements and sub-advisory agreements.

In connection with its evaluation of the investment advisory agreements and sub-advisory agreements, the Board considered various information relating to the Eaton Vance Funds. This included information applicable to all or groups of Eaton Vance Funds, which is referenced immediately below, and information applicable to the particular Eaton Vance Fund covered by this report (additional fund-specific information is referenced below under “Results of the Contract Review Process”). (For funds that invest through one or more underlying portfolios, references to “each fund” in this section may include information that was considered at the portfolio-level.)

• Descriptions of the investment management services provided to each fund, as well as each of the funds’ investment strategies and policies;

• The procedures and processes used to determine the fair value of fund assets, when necessary, and actions taken to monitor and test the effectiveness of such procedures and processes;

• Information about the policies and practices of each fund’s adviser and sub-adviser (in the context of a sub-adviser, only those with trading responsibilities) with respect to trading, including their processes for seeking best execution of portfolio transactions;

• Information about the allocation of brokerage transactions and the benefits, if any, received by the adviser and sub-adviser (in the context of a sub-adviser, only those with trading responsibilities) to each fund as a result of brokerage allocation, including, as applicable, information concerning the acquisition of research through client commission arrangements and policies with respect to “soft dollars”;

• Data relating to the portfolio turnover rate of each fund;

• Reports detailing the financial results and condition of the adviser and sub-adviser to each fund;

• Information regarding the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and, for portfolio managers and certain other investment professionals, information relating to their responsibilities with respect to managing other mutual funds and investment accounts, as applicable;

⁽¹⁾  Not all Eaton Vance Funds have entered into a sub-advisory agreement with a sub-adviser. Accordingly, references to “sub-adviser” or “sub-advisory agreement” in this “Overview” section may not be applicable to the particular Eaton Vance Fund covered by this report.

• Policies and procedures relating to proxy voting and the handling of corporate actions and class actions;

• Information concerning the resources devoted to compliance efforts undertaken by the adviser and its affiliates and the sub-adviser of each fund, if any, including descriptions of their various compliance programs and their record of compliance;

During the various meetings of the Board and its committees throughout the twelve months ended April 2020, the Trustees received information from portfolio managers and other investment professionals of the advisers and sub-advisers of the funds regarding investment and performance matters, and considered various investment and trading strategies used in pursuing the funds’ investment objectives. The Trustees 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 and participated in reports and presentations provided by Eaton Vance Management, Boston Management and Research and fund sub-advisers, with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Trustees held regular teleconferences to discuss, among other topics, matters relating to the continuation of investment advisory agreements and sub-advisory agreements.

The Contract Review Committee was advised throughout the contract review 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 each investment advisory agreement and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each investment advisory agreement and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Contract Review Committee may have placed varying emphasis on particular factors in reaching conclusions with respect to each investment advisory agreement and sub-advisory agreement. In evaluating each investment advisory agreement and sub-advisory agreement, including the fee structures and other terms contained in such agreements, the members of the Contract Review Committee were also informed by multiple years of analysis and discussion with the adviser and sub-adviser to each of the Eaton Vance Funds.

In voting its approval of the continuation of existing investment advisory agreements and sub-advisory agreements at the April 2020 Meeting, the Board relied on an order issued by the Securities and Exchange Commission on March 25, 2020, which provided temporary relief from the in-person voting requirements under Section 15 of the 1940 Act in response to the impacts of the COVID-19 pandemic.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information it deemed relevant, including the factors and conclusions described below, the Contract Review Committee concluded that the continuation of the investment advisory agreement between Eaton Vance Core Plus Bond Fund (the “Fund”) and Boston Management and Research (the “Adviser”), including its fee structure, is in the interests of shareholders and, therefore, recommended to the Board approval of the agreement. Based on the recommendation of the Contract Review Committee, the Board, including a majority of the Independent Trustees, voted to approve continuation of the investment advisory agreement for the Fund.

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory agreement for the Fund, the Board evaluated the nature, extent and quality of services provided to the Fund by the Adviser.

The Board considered the Adviser’s management capabilities and investment processes in light of the types of investments held by the Fund, including the education, experience and number of investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Fund, including recent changes to such personnel. The Board considered, where relevant, the abilities and experience of the Adviser’s investment professionals in analyzing factors such as credit risk and special considerations relevant to investing in income securities. The Board considered the Adviser’s in-house research capabilities. The Board also took into account the resources dedicated to portfolio management and other services, the

33

Eaton Vance

Core Plus Bond Fund

Board of Trustees’ Contract Approval — continued

compensation methods of the Adviser and other factors, including the reputation and resources of the Adviser to recruit and retain highly qualified research, advisory and supervisory investment professionals. In addition, the Board considered the time and attention devoted to the Eaton Vance Funds, including the Fund, 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 Fund, including the provision of administrative services. The Board also considered the business-related and other risks to which the Adviser or its affiliates may be subject in managing the Fund.

The Board considered the compliance programs of the Adviser and relevant affiliates thereof. The Board considered compliance and reporting matters regarding, among other things, personal trading by investment professionals, disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also considered the responses of the Adviser 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 considered other administrative services provided or overseen by Eaton Vance Management 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, as well as the ability, in many cases, to exchange an investment among different funds without incurring additional sales charges.

After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by the Adviser, taken as a whole, are appropriate and consistent with the terms of the investment advisory agreement.

Fund Performance

The Board compared the Fund’s investment performance to that of comparable funds identified by an independent data provider (the peer group), as well as an appropriate benchmark index. The Board’s review included comparative performance data with respect to the Fund for the one-, three- and five-year periods ended September 30, 2019. In this regard, the Board noted that the performance of the Fund was higher than the median performance of the Fund’s peer group for the three-year period. The Board also noted that the performance of the Fund was higher than its benchmark index for the three-year period. The Board concluded that the performance of the Fund was satisfactory.

Management Fees and Expenses

The Board considered contractual fee rates payable by the Fund for advisory and administrative services (referred to collectively as “management fees”). As part of its review, the Board considered the Fund’s management fees and total expense ratio for the one-year period ended September 30, 2019, 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 that had an impact on the Fund’s total expense ratio relative to comparable funds.

After considering the foregoing information, and in light of the nature, extent and quality of the services provided by the Adviser, the Board concluded that the management fees charged for advisory and related services are reasonable.

Profitability and “Fall-Out” Benefits

The Board considered the level of profits realized by the Adviser and relevant affiliates thereof in providing investment advisory and administrative services to the Fund 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 the Adviser and its affiliates to third parties in respect of distribution or other services.

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by the Adviser and its affiliates are deemed not to be excessive.

The Board also considered direct or indirect fall-out benefits received by the Adviser and its affiliates in connection with their respective relationships with the Fund, including the benefits of research services that may be available to the Adviser as a result of securities transactions effected for the Fund and other investment advisory clients.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the Adviser and its affiliates, on the one hand, and the Fund, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund 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. The Board reviewed data summarizing the increases and decreases in the assets of the Fund and of all Eaton Vance Funds as a group over various time periods, and evaluated the extent to which the total expense ratio of the Fund and the profitability of the Adviser and its affiliates may have been affected by such increases or decreases. Based upon the foregoing, the Board concluded that the Fund currently shares in the benefits from economies of scale, if any, when they are realized by the Adviser. The Board also concluded that the structure of the advisory fee, which includes breakpoints at several asset levels, will allow the Fund to continue to benefit from any economies of scale in the future.

Liquidity Risk Management Program

The Fund has implemented a written liquidity risk management program (Program) and related procedures to manage its liquidity in accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (Liquidity Rule). The Liquidity Rule defines “liquidity risk” as the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of the remaining investors’ interests in the fund. The Fund’s Board of Trustees/Directors has designated the investment adviser to serve as the administrator of the Program and the related procedures. The administrator has established a Liquidity Risk Management Oversight Committee (Committee) to perform the functions necessary to administer the Program. As part of the Program, the administrator is responsible for identifying illiquid investments and categorizing the relative liquidity of the Fund’s investments in accordance with the Liquidity Rule. Under the Program, the administrator assesses, manages, and periodically reviews the Fund’s liquidity risk, and is responsible for making certain reports to the Fund’s Board of Trustees/Directors and the Securities and Exchange Commission (SEC) regarding the liquidity of the Fund’s investments, and to notify the Board of Trustees/Directors and the SEC of certain liquidity events specified in the Liquidity Rule. The liquidity of the Fund’s portfolio investments is determined based on a number of factors including, but not limited to, relevant market, trading and investment-specific considerations under the Program.

At a meeting of the Fund’s Board of Trustees/Directors, the Committee provided a written report to the Fund’s Board of Trustees/Directors pertaining to the operation, adequacy, and effectiveness of implementation of the Program, as well as the operation of the highly liquid investment minimum (if applicable) for the period December 1, 2018 through December 31, 2019 (Review Period). The Program operated effectively during the Review Period, supporting the administrator’s ability to assess, manage and monitor Fund liquidity risk, including during periods of market volatility and net redemptions. During the Review Period, the Fund met redemption requests on a timely basis.

There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

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. Each investment adviser has claimed an exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of each Fund. Accordingly, neither the Funds nor the adviser with respect to the operation of the Funds is subject to CFTC regulation. Because of its management of other strategies, each Fund’s adviser is registered with the CFTC as a commodity pool operator. Each adviser is also registered as a commodity trading advisor.

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

As the 12-month period opened on October 1, 2019, Treasury and municipal bond rates were trending modestly upward, amid better- than-expected U.S. employment reports and cautious optimism about a détente in U.S.-China trade relations. Rates continued to move upward through the end of 2019.

In January 2020, however, news of the outbreak of a new coronavirus in China raised investor concerns and led to a “flight to quality” that sparked a brief bond market rally. As the virus turned into a global pandemic in February and March, however, it ended the longest-ever U.S. economic expansion and brought about a global economic slowdown. Economic activity decreased and credit markets, along with equities, declined in value amid significant volatility.

In response, the U.S. Federal Reserve (the Fed) announced two emergency rate cuts in March 2020 — lowering the federal funds rate to 0.00%-0.25% — along with other measures intended to shore up credit markets. At its July meeting, the Fed provided additional reassurances that it would maintain rates around zero for the foreseeable future and use all the monetary tools at its disposal to support the U.S. economy. These moves helped calm the markets and initiated a new municipal bond rally that began in April and lasted through most of the summer.

The municipal bond rally was also driven by technical market factors as demand overwhelmed supply. As municipal bonds offered attractive tax-exempt yields versus other fixed-income asset classes, municipal bond funds reported net inflows from May through September 2020 — following substantial outflows in March and April.

Midway through August, however, the municipal rally stalled. Rates hit bottom for the fiscal year on August 11, with 10-year municipal bonds at a yield of 0.58%. During the rest of the period, prices fell and yields rose, driven in part by Congress’ failure to pass another stimulus bill, $400-$500 billion of which had been projected for state and local government assistance.

As issuers rushed to take advantage of low yields in late August and September, increased supply reversed the supply-demand dynamic from earlier in the summer — putting further downward pressure on municipal bond prices and upward pressure on yields. In addition, the Fed announced at the end of August a policy shift to allow inflation to run above its 2% target until the U.S. unemployment rate is very low — raising inflation concerns among some investors.

For the period as a whole, rates declined across the municipal bond yield curve, with the greatest declines occurring at the short end of the curve. The Bloomberg Barclays Municipal Bond Index (the Index), a broad measure of the asset class, returned 4.09% during the period — despite a 3.63% decline in March 2020. Reflecting investors’ “flight to quality” in response to the pandemic, municipal bonds with higher credit ratings generally outperformed lower rated issues during the period.

Fund Performance

For the 12-month period ended September 30, 2020, Eaton Vance AMT-Free Municipal Income Fund Class A shares at net asset value (NAV) and Eaton Vance National Municipal Income Fund Class A shares at NAV both underperformed the 4.09% return of the Funds’ benchmark, the Index.

The Funds’ overall strategy is to normally invest in bonds with maturities of 10 years or more, in order to pursue their potentially higher yields and a greater income stream compared with shorter maturity issues.

The Funds may seek to enhance tax-exempt income through the use of leveraged investments by purchasing residual interest bonds. Leveraged investments have the effect of magnifying the Funds’ exposure to their underlying investments in both up and down markets. During this period, when rates fell and bond prices rose for the period as a whole, leveraged investments amplified the appreciation in the price of bonds held by the Funds and generated additional tax-exempt bond income, enhancing the total return of the Funds. By comparison, the Index does not employ leveraged investments. The Fed’s actions during the period to lower interest rates also reduced the borrowing costs associated with residual interest bonds, further contributing to the positive performance impact of the Funds’ leveraged investments.

Fund-Specific Results

Eaton Vance AMT-Free Municipal Income Fund returned 3.12% for Class A shares at NAV, underperforming the 4.09% return of the Index during the period. Detractors from results relative to the Index included security selection and an overweight position, relative to the Index, in Illinois bonds; security selection in the education sector; and overweight positions in bonds rated A and BBB. In contrast, contributors to Fund performance versus the Index included leveraged investments, security selection in the electric utilities sector, and an overweight position in zero-coupon bonds.

Eaton Vance National Municipal Income Fund returned 3.84% for Class A shares at NAV, underperforming the 4.09% return of the Index during the period. Detractors from performance versus the Index included an overweight in bonds from issuers in New York and Illinois — two of the financially hardest-hit states early in the coronavirus pandemic — as prices of those bonds declined due to uncertainty about the economic effects of the pandemic. Security selection in zero-coupon bonds also detracted from relative results, as did security selection in the transportation sector, which was hurt by plunging revenues from travel and public transit. Contributors to performance relative to the Index included leveraged investments; security selection in general obligation bonds; and the Fund’s allocation to taxable municipal bonds, which are not represented in the Index and generally outperformed tax-exempt municipal bonds during the period.

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 offering price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when redeemed, 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.

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 offering price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when redeemed, 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.

¹  The views expressed in this report are those of the portfolio manager(s) and are current only through the date stated at the top of this page. These views are subject to change at any time based upon market or other conditions, and Eaton Vance and the Fund(s) disclaim any responsibility to update such views. These views may not be relied upon as investment advice and, because investment decisions are based on many factors, may not be relied upon as an indication of trading intent on behalf of any Eaton Vance fund. This commentary may contain statements that are not historical facts, referred to as “forward-looking statements.” The Fund’s actual future results may differ significantly from those stated in any forward-looking statement, depending on factors such as changes in securities or financial markets or general economic conditions, the volume of sales and purchases of Fund shares, the continuation of investment advisory, administrative and service contracts, and other risks discussed from time to time in the Fund’s filings with the Securities and Exchange Commission.

²  Bloomberg Barclays Municipal Bond Index is an unmanaged index of municipal bonds traded in the U.S. Unless otherwise stated, index returns do not reflect the effect of any applicable sales charges, commissions, expenses, taxes or leverage, as applicable. It is not possible to invest directly in an index.

³  Total Returns at NAV do not include applicable sales charges. If sales charges were deducted, the returns would be lower. Total Returns shown with maximum sales charge reflect the stated maximum sales charge. Unless otherwise stated, performance does not reflect the deduction of taxes on Fund distributions or redemptions of Fund shares.

⁴  Source: Fund prospectus. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report.

⁵  The Distribution Rate is based on the Fund’s last regular distribution per share in the period (annualized) divided by the Fund’s NAV at the end of the period. The Fund’s distributions may be comprised of amounts characterized for federal income tax purposes as tax-exempt income, qualified and non-qualified ordinary dividends, capital gains and nondividend distributions, also known as return of capital. The Fund will determine the federal income tax character of distributions paid to a shareholder after the end of the calendar year. This is reported on the IRS form 1099- DIV and provided to the shareholder shortly after each year-end. The Fund’s distributions are determined by the investment adviser based on its current assessment of the Fund’s long-term return potential. As portfolio and market conditions change, the rate of distributions paid by the Fund could change. Taxable-equivalent performance is based on the highest combined federal and state income tax rates, where applicable. Lower tax rates would result in lower tax-equivalent performance. Actual tax rates will vary depending on your income, exemptions and deductions. Rates do not include local taxes. The SEC Yield is a standardized measure based on the estimated yield to maturity of a fund’s investments over a 30-day period and is based on the maximum offer price at the date specified. The SEC Yield is not based on the distributions made by the Fund, which may differ.

⁶  Fund employs RIB financing. The leverage created by RIB investments provides an opportunity for increased income but, at the same time, creates special risks (including the likelihood of greater volatility of NAV). The cost of leverage rises and falls with changes in short-term interest rates. See “Floating Rate Notes Issued in Conjunction with Securities Held” in the notes to the financial statements for more information about RIB financing. RIB leverage represents the amount of Floating Rate Notes outstanding at period end as a percentage of Fund net assets plus Floating Rate Notes.

⁷  Ratings are based on Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings (“S&P”) or Fitch Ratings (“Fitch”), as applicable. If securities are rated differently by the ratings agencies, the highest rating is applied. Ratings, which are subject to change, apply to the creditworthiness of the issuers of the underlying securities and not to the Fund or its shares. Credit ratings measure the quality of a bond based on the issuer’s creditworthiness, with ratings ranging from AAA, being the highest, to D, being the lowest based on S&P’s measures. Ratings of BBB or higher by S&P or Fitch (Baa or higher by Moody’s) are considered to be investment-grade quality. Credit ratings are based largely on the ratings agency’s analysis at the time of rating. The rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition and does not necessarily reflect its assessment of the volatility of a security’s market value or of the liquidity of an investment in the security. Holdings designated as “Not Rated” (if any) are not rated by the national ratings agencies stated above.

⁸  The chart includes the municipal bonds held by a trust that issues residual interest bonds, consistent with the Portfolio of Investments.

Fund profiles subject to change due to active management.

Additional Information

Yield curve is a graphical representation of the yields offered by bonds of various maturities. The yield curve flattens when long-term interest rates fall and/or short-term interest rates increase, and the yield curve steepens when long-term interest rates increase and/or short-term interest rates fall.

Fund Expenses

Example:  As a Fund shareholder, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchases and redemption fees (if applicable); and (2) ongoing costs, including management fees; distribution and/or service fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of Fund investing and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (April 1, 2020 – September 30, 2020).

Actual Expenses:  The first section of each table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes:  The second section of each table below provides information about hypothetical account values and hypothetical expenses based on the actual Fund expense ratio and an assumed rate of return of 5% per year (before expenses), which is not the actual Fund return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in each table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption fees (if applicable). Therefore, the second section of each table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would be higher.

1  Significant Accounting Policies

Eaton Vance AMT-Free Municipal Income Fund (AMT-Free Fund) and Eaton Vance National Municipal Income Fund (National Fund) (each individually referred to as the Fund, and collectively, the Funds) are a diversified series of Eaton Vance Mutual Funds Trust and Eaton Vance Municipals Trust, respectively (collectively, the Trusts). The Trusts are Massachusetts business trusts registered under the Investment Company Act of 1940, as amended (the 1940 Act), as open-end management investment companies. The Funds’ investment objective is to provide current income exempt from regular federal income tax. The Funds offer three classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. Class C shares are sold at net asset value and are generally subject to a contingent deferred sales charge (see Note 5). Effective January 25, 2019, Class C shares generally automatically convert to Class A shares ten years after their purchase and, effective November 5, 2020, automatically convert to Class A shares eight years after their purchase as described in the Funds’ prospectus. Class I shares are sold at net asset value and are not subject to a sales charge. Each class represents a pro-rata interest in the Fund, but votes separately on class-specific matters and (as noted below) is subject to different expenses. Realized and unrealized gains and losses are allocated daily to each class of shares based on the relative net assets of each class to the total net assets of the Fund. Net investment income, other than class-specific expenses, is allocated daily to each class of shares based upon the ratio of the value of each class’s paid shares to the total value of all paid shares. Each class of shares differs in its distribution plan and certain other class-specific expenses.

The following is a summary of significant accounting policies of the Funds. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). Each 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.

Debt Obligations. Debt obligations are generally valued on the basis of valuations provided by third party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and ask prices, broker/dealer quotations, prices or yields of securities with similar characteristics, interest rates, anticipated prepayments, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. Short-term debt obligations purchased with a remaining maturity of sixty days or less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value.

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 a Fund in a manner that most fairly reflects the security’s “fair value”, which is the amount that a 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 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 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 and Related Income — 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. Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount.

C  Federal Taxes — Each 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 taxable, if any, and tax-exempt 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. Each Fund intends to satisfy conditions which will enable it to designate distributions from the interest income generated by its investments in non-taxable municipal securities, which are exempt from regular federal income tax when received by each Fund, as exempt-interest dividends. For National Fund, the portion of such interest, if any, earned on private activity bonds issued after August 7, 1986, may be considered a tax preference item to shareholders.

As of September 30, 2020, the Funds had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. Each 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.

D  Expenses — The majority of expenses of the Trusts are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated taking into consideration, among other things, the nature and type of expense and the relative size of the funds.

E  Legal Fees — Legal fees and other related expenses incurred as part of negotiations of the terms and requirement of capital infusions, or that are expected to result in the restructuring of, or a plan of reorganization for, an investment are recorded as realized losses. Ongoing expenditures to protect or enhance an investment are treated as operating expenses.

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 each Trust’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 Funds. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as a Trust) could be deemed to have personal liability for the obligations of the Trust. However, each Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and the By-laws provide that the Trust 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, each Fund enters into agreements with service providers that may contain indemnification clauses. Each Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against each Fund that have not yet occurred.

H  Floating Rate Notes Issued in Conjunction with Securities Held — The Funds may invest in residual interest bonds, also referred to as inverse floating rate securities, whereby a Fund may sell a variable or fixed rate bond for cash to a Special-Purpose Vehicle (the SPV), (which is generally organized as a trust), while at the same time, buying a residual interest in the assets and cash flows of the SPV. The bond is deposited into the SPV with the same CUSIP number as the bond sold to the SPV by the Fund, and which may have been, but is not required to be, the bond purchased from the Fund (the Bond). The SPV also issues floating rate notes (Floating Rate Notes) which are sold to third-parties. The residual interest bond held by a Fund gives the Fund the right (1) to cause the holders of the Floating Rate Notes to generally tender their notes at par, and (2) to have the Bond held by the SPV transferred to the Fund, thereby terminating the SPV. Should the Fund exercise such right, it would generally pay the SPV the par amount due on the Floating Rate Notes and exchange the residual interest bond for the underlying Bond. Pursuant to generally accepted accounting principles for transfers and servicing of financial assets and extinguishment of liabilities, the Funds account for the transaction described above as a secured borrowing by including the Bond in their Portfolio of Investments and the Floating Rate Notes as a liability under the caption “Payable for floating rate notes issued” in their Statement of Assets and Liabilities. The Floating Rate Notes have interest rates that generally reset weekly and their holders have the option to tender their notes to the SPV for redemption at par at each reset date. Accordingly, the fair value of the payable for floating rate notes issued approximates its carrying value. If measured at fair value, the payable for floating rate notes would have been considered as Level 2 in the fair value hierarchy (see Note 9) at September 30, 2020. Interest expense related to a Fund’s liability with respect to Floating Rate Notes is recorded as incurred. The SPV may be terminated by the Fund, as noted above, or by the occurrence of certain termination events as defined in the trust agreement, such as a downgrade in the credit quality of the underlying Bond, bankruptcy of or payment failure by the issuer of the underlying Bond, the inability to remarket Floating Rate Notes that have been tendered due to insufficient buyers in the market, or the failure by the SPV to obtain renewal of the liquidity agreement under which liquidity support is provided for the Floating Rate Notes up to one year. At September 30, 2020, the amounts of the Funds’ Floating Rate Notes and related interest rates and collateral were as follows:

	AMT-Free Fund		National Fund
Floating Rate Notes Outstanding	$	29,836,363	$	104,543,843
Interest Rate or Range of Interest Rates (%)		0.15 - 0.17		0.10 - 0.22
Collateral for Floating Rate Notes Outstanding	$	47,030,581	$	151,951,045

For the year ended September 30, 2020, the Funds’ average settled Floating Rate Notes outstanding and the average interest rate including fees were as follows:

	AMT-Free Fund			National Fund
Average Floating Rate Notes Outstanding	$	29,775,000		$	108,824,959
Average Interest Rate		1.50	%		1.46	%

In certain circumstances, the Funds may enter into shortfall and forbearance agreements with brokers by which a Fund agrees to reimburse the broker for the difference between the liquidation value of the Bond held by the SPV and the liquidation value of the Floating Rate Notes, as well as any shortfalls in interest cash flows. The Funds had no shortfalls as of September 30, 2020.

The Funds may also purchase residual interest bonds in a secondary market transaction without first owning the underlying bond. Such transactions are not required to be treated as secured borrowings. Shortfall agreements, if any, related to residual interest bonds purchased in a secondary market transaction are disclosed in the Portfolio of Investments.

The Funds’ investment policies and restrictions expressly permit investments in residual interest bonds. Such bonds typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality and maturity. These securities tend to underperform the market for fixed rate bonds in a rising long-term interest rate environment, but tend to outperform the market for fixed rate bonds when long-term interest rates decline. The value and income of residual interest bonds are generally more volatile than that of a fixed rate bond. The Funds’ investment policies do not allow the

Funds to borrow money except as permitted by the 1940 Act. Management believes that the Funds’ restrictions on borrowing money and issuing senior securities (other than as specifically permitted) do not apply to Floating Rate Notes issued by the SPV and included as a liability in the Funds’ Statement of Assets and Liabilities. As secured indebtedness issued by an SPV, Floating Rate Notes are distinct from the borrowings and senior securities to which the Funds’ restrictions apply. Residual interest bonds held by the Funds are securities exempt from registration under Rule 144A of the Securities Act of 1933.

I  When-Issued Securities and Delayed Delivery Transactions — The Funds may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. At the time the transaction is negotiated, the price of the security that will be delivered is fixed. The Funds maintain cash and/or security positions for these commitments such that sufficient liquid assets will be available to make payments upon settlement. Securities purchased on a delayed delivery or when-issued basis are marked-to-market daily and begin earning interest on settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

2  Distributions to Shareholders and Income Tax Information

The net investment income of each Fund is determined daily and substantially all of the net investment income so determined is declared as a dividend to shareholders of record at the time of declaration. Distributions are declared separately for each class of shares. Distributions are paid monthly. Distributions of realized capital gains are made at least annually. Shareholders may reinvest income and capital gain distributions in additional shares of the same class of a Fund at the net asset value as of the reinvestment date or, at the election of the shareholder, receive distributions in cash. 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.

The tax character of distributions declared for the years ended September 30, 2020 and September 30, 2019 was as follows:

	AMT-Free Fund				National Fund
	Year Ended September 30,				Year Ended September 30,
	2020		2019		2020		2019
Tax-exempt income	$	10,435,763	$	10,804,193	$	88,786,223	$	85,494,039
Ordinary income	$	757	$	76,376	$	4,932,347	$	4,944,533

As of September 30, 2020, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

	AMT-Free Fund			National Fund
Undistributed tax-exempt income	$	1,235,291		$	5,256,119
Deferred capital losses	$	(28,640,391	)	$	(166,281,868	)
Net unrealized appreciation	$	26,159,481		$	198,922,269
Distributions payable	$	(124,202	)	$	(1,275,089	)

At September 30, 2020, the following Funds, for federal income tax purposes, had deferred capital losses which would reduce the respective Fund’s 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 Funds of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of a Fund’s next taxable year and retain the same short-term or long-term character as when originally deferred. The amounts of the deferred capital losses are as follows:

	AMT-Free Fund		National Fund
Deferred capital losses:
Short-term	$	15,794,902	$	111,957,326
Long-term	$	12,845,489	$	54,324,542

The cost and unrealized appreciation (depreciation) of investments of each Fund at September 30, 2020, as determined on a federal income tax basis, were as follows:

	AMT-Free Fund			National Fund
Aggregate cost	$	311,169,986		$	3,397,966,601
Gross unrealized appreciation	$	28,084,171		$	220,783,592
Gross unrealized depreciation		(1,924,690	)		(21,861,323	)
Net unrealized appreciation	$	26,159,481		$	198,922,269

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., for AMT-Free Fund and Boston Management and Research (BMR), a subsidiary of EVM and an indirect subsidiary of Eaton Vance Corp., for National Fund as compensation for management and investment advisory services rendered to each Fund. The fee is based upon a percentage of average daily net assets plus a percentage of gross income (i.e., income other than gains from the sale of securities) as presented in the following table and is payable monthly.

Daily Net Assets	Annual Asset Rate			Daily Income Rate
Up to $500 million		0.300	%		3.00	%
$500 million but less than $1 billion		0.275			2.75
$1 billion but less than $1.5 billion		0.250			2.50
$1.5 billion but less than $2 billion		0.225			2.25
$2 billion but less than $3 billion		0.200			2.00
$3 billion and over		0.175			1.75

For the year ended September 30, 2020, investment adviser fees incurred by the Funds and the effective annual rates, as a percentage of average daily net assets, were as follows:

	AMT-Free Fund			National Fund
Investment Adviser Fee	$	1,359,467		$	10,209,281
Effective Annual Rate		0.41	%		0.31	%

EVM serves as the administrator of each Fund, but receives no compensation. EVM provides sub-transfer agency and related services to the Funds pursuant to a Sub-Transfer Agency Support Services Agreement. Eaton Vance Distributors, Inc. (EVD), an affiliate of EVM and the Funds’ principal underwriter, received a portion of the sales charge on sales of Class A shares of the Funds. EVD also received distribution and service fees from Class A and Class C shares (see Note 4) and contingent deferred sales charges (see Note 5). Sub-transfer agent fees earned by EVM, which are included in transfer and dividend disbursing agent fees on the Statements of Operations, and Class A sales charges that the Funds were informed were received by EVD for the year ended September 30, 2020 were as follows:

	AMT-Free Fund		National Fund
EVM’s Sub-Transfer Agent Fees	$	11,077	$	128,978
EVD’s Class A Sales Charges	$	13,353	$	139,301

Trustees and officers of the Funds who are members of EVM’s or BMR’s organizations receive remuneration for their services to the Funds out of the investment adviser fee. Trustees of the Funds who are not affiliated with the investment advisers 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 September 30, 2020, no significant amounts have been deferred. Certain officers and Trustees of the Funds are officers of the above organizations.

4  Distribution Plans

Each Fund has in effect a distribution plan for Class A shares (Class A Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, each Fund pays EVD a distribution and service fee of 0.25% per annum of its average daily net assets attributable to Class A shares for distribution services and facilities provided to each Fund by EVD, as well as for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued to EVD for the year ended September 30, 2020 for Class A shares amounted to the following:

	AMT-Free Fund		National Fund
Class A Distribution and Service Fees	$	378,484	$	3,984,013

Each Fund also has in effect a distribution plan for Class C shares (Class C Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class C Plan, each Fund pays EVD amounts equal to 0.75% per annum of its average daily net assets attributable to Class C shares for providing ongoing distribution services and facilities to the respective Funds. For the year ended September 30, 2020, the Funds paid or accrued to EVD the following distribution fees:

	AMT-Free Fund		National Fund
Class C Distribution Fees	$	134,677	$	1,174,026

The Class C Plan also authorizes each Fund to make payments of service fees to EVD, financial intermediaries and other persons in amounts equal to 0.25% per annum of the average daily net assets attributable to Class C shares. Service fees paid or accrued are for personal services and/or the maintenance of shareholder accounts. They are separate and distinct from the Class C sales commissions and distribution fees payable to EVD. Service fees paid or accrued for the year ended September 30, 2020 amounted to the following:

	AMT-Free Fund		National Fund
Class C Service Fees	$	44,892	$	391,342

Distribution and service fees are subject to the limitations contained in the Financial Industry Regulatory Authority Rule 2341(d).

5  Contingent Deferred Sales Charges

A contingent deferred sales charge (CDSC) of 1% generally is imposed on redemptions of Class C shares made within 12 months of purchase. Class A shares may be subject to a 1% CDSC if redeemed within 18 months of purchase (depending on the circumstances of purchase). Generally, the CDSC is based upon the lower of the net asset value at date of redemption or date of purchase. No charge is levied on shares acquired by reinvestment of dividends or capital gain distributions. For the year ended September 30, 2020, the Funds were informed that EVD received approximately the following amounts of CDSCs paid by Class A and Class C shareholders:

	AMT-Free Fund		National Fund
Class A	$	20	$	39,000
Class C	$	50	$	17,000

8  Line of Credit

The Funds participate with other portfolios and funds managed by EVM and its affiliates in an $800 million unsecured line of credit agreement with a group of banks, which is in effect through October 27, 2020. In connection with the renewal of the agreement on October 29, 2019, funds managed by Calvert Research and Management, an affiliate of EVM, were added as participating funds to the agreement and the borrowing limit was increased from $625 million. Borrowings are made by the Funds solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to each Fund based on its borrowings at an amount above either the Eurodollar rate or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. Because the line of credit is not available exclusively to the Funds, a Fund may be unable to borrow some or all of its requested amounts at any particular time. The Funds did not have any significant borrowings or allocated fees during the year ended September 30, 2020.

Effective October 27, 2020, the Funds renewed their line of credit agreement, which expires October 26, 2021, at substantially the same terms.

9  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.

At September 30, 2020, the hierarchy of inputs used in valuing the Funds’ investments, which are carried at value, were as follows:

AMT-Free Fund
Asset Description	Level 1		Level 2		Level 3		Total
Tax-Exempt Investments	$	—	$	367,165,830	$	—	$	367,165,830
Total Investments	$	—	$	367,165,830	$	—	$	367,165,830

10  Risks and Uncertainties

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 Funds’ performance, or the performance of the securities in which the Funds invest.

11  Subsequent Event

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 result in the automatic termination of each Fund’s investment advisory agreement, and any related sub-advisory agreement(s), if applicable. Thus, each Fund’s Board will be asked to approve a new investment advisory agreement (and new sub-advisory agreement(s), if applicable). If approved by each Fund’s Board, the new investment advisory agreement (and new sub-advisory agreement(s), if applicable) is expected to be presented to Fund shareholders for approval, and, if approved, would take effect upon the closing of the transaction.

Board of Trustees’ Contract Approval

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended (the “1940 Act”), provides, in substance, that the investment advisory agreement between a fund and its investment adviser will continue in effect from year-to-year only if its continuation is approved on an annual basis by a vote of the fund’s board of trustees, including a majority of the trustees who are not “interested persons” of the fund (“independent trustees”), cast in person at a meeting called for the purpose of considering such approval.

At a meeting held on April 22, 2020 (the “April 2020 Meeting”), the Boards of Trustees/Directors comprised of the same individuals (collectively, the “Board”) that oversees a majority of the registered investment companies advised by Eaton Vance Management or its affiliate, Boston Management and Research (the “Eaton Vance Funds”), including a majority of the independent trustees (the “Independent Trustees”), voted to approve the continuation of existing investment advisory agreements and sub-advisory agreements⁽¹⁾ for each of the Eaton Vance Funds for an additional one-year period. The Board relied upon the affirmative recommendation of its Contract Review Committee, which is a committee exclusively comprised of Independent Trustees. Prior to making its recommendation, the Contract Review Committee reviewed information furnished by the adviser and sub-adviser to each of the Eaton Vance Funds (including information specifically requested by the Board) for a series of formal meetings held between February and April 2020. Members of the Contract Review Committee also considered information received at prior meetings of the Board and its committees, to the extent such information was relevant to the Contract Review Committee’s annual evaluation of the investment advisory agreements and sub-advisory agreements.

In connection with its evaluation of the investment advisory agreements and sub-advisory agreements, the Board considered various information relating to the Eaton Vance Funds. This included information applicable to all or groups of Eaton Vance Funds, which is referenced immediately below, and information applicable to the particular Eaton Vance Fund covered by this report (additional fund-specific information is referenced below under “Results of the Contract Review Process”). (For funds that invest through one or more underlying portfolios, references to “each fund” in this section may include information that was considered at the portfolio-level.)

Information about Fees, Performance and Expenses

• A report from an independent data provider comparing advisory and other fees paid by each fund to such fees paid by comparable funds, as identified by the independent data provider (“comparable funds”);

Information about Portfolio Management and Trading

• Descriptions of the investment management services provided to each fund, as well as each of the funds’ investment strategies and policies;

• The procedures and processes used to determine the fair value of fund assets, when necessary, and actions taken to monitor and test the effectiveness of such procedures and processes;

• Information about the policies and practices of each fund’s adviser and sub-adviser (in the context of a sub-adviser, only those with trading responsibilities) with respect to trading, including their processes for seeking best execution of portfolio transactions;

• Information about the allocation of brokerage transactions and the benefits, if any, received by the adviser and sub-adviser (in the context of a sub-adviser, only those with trading responsibilities) to each fund as a result of brokerage allocation, including, as applicable, information concerning the acquisition of research through client commission arrangements and policies with respect to “soft dollars”;

• Data relating to the portfolio turnover rate of each fund;

Information about each Adviser and Sub-adviser

• Reports detailing the financial results and condition of the adviser and sub-adviser to each fund;

• Information regarding the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and, for portfolio managers and certain other investment professionals, information relating to their responsibilities with respect to managing other mutual funds and investment accounts, as applicable;

⁽¹⁾  Not all Eaton Vance Funds have entered into a sub-advisory agreement with a sub-adviser. Accordingly, references to “sub-adviser” or “sub-advisory agreement” in this “Overview” section may not be applicable to the particular Eaton Vance Fund covered by this report.

• Policies and procedures relating to proxy voting and the handling of corporate actions and class actions;

• Information concerning the resources devoted to compliance efforts undertaken by the adviser and its affiliates and the sub-adviser of each fund, if any, including descriptions of their various compliance programs and their record of compliance;

Other Relevant Information

• The terms of each investment advisory agreement and sub-advisory agreement.

During the various meetings of the Board and its committees throughout the twelve months ended April 2020, the Trustees received information from portfolio managers and other investment professionals of the advisers and sub-advisers of the funds regarding investment and performance matters, and considered various investment and trading strategies used in pursuing the funds’ investment objectives. The Trustees 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 and participated in reports and presentations provided by Eaton Vance Management, Boston Management and Research and fund sub-advisers, with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Trustees held regular teleconferences to discuss, among other topics, matters relating to the continuation of investment advisory agreements and sub-advisory agreements.

The Contract Review Committee was advised throughout the contract review 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 each investment advisory agreement and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each investment advisory agreement and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Contract Review Committee may have placed varying emphasis on particular factors in reaching conclusions with respect to each investment advisory agreement and sub-advisory agreement. In evaluating each investment advisory agreement and sub-advisory agreement, including the fee structures and other terms contained in such agreements, the members of the Contract Review Committee were also informed by multiple years of analysis and discussion with the adviser and sub-adviser to each of the Eaton Vance Funds.

In voting its approval of the continuation of existing investment advisory agreements and sub-advisory agreements at the April 2020 Meeting, the Board relied on an order issued by the Securities and Exchange Commission on March 25, 2020, which provided temporary relief from the in-person voting requirements under Section 15 of the 1940 Act in response to the impacts of the COVID-19 pandemic.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information it deemed relevant, including the factors and conclusions described below, the Contract Review Committee concluded that (i) the continuation of the investment advisory agreement between Eaton Vance AMT-Free Municipal Income Fund (the “AMT-Free Muni Income Fund”) and Eaton Vance Management (“EVM”) and (ii) the continuation of the investment advisory agreement between Eaton Vance National Municipal Income Fund (the “National Muni Income Fund”, together with the AMT-Free Muni Income Fund, the “Funds” and each, a “Fund”) and Boston Management and Research (“BMR”) (EVM, with respect to the AMT-Free Muni Income Fund, and BMR, with respect to the National Muni Income Fund, are each referred to herein as the “Adviser”), including their respective fee structures, are in the interests of shareholders and, therefore, recommended to the Board approval of each agreement. Based on the recommendation of the Contract Review Committee, the Board, including a majority of the Independent Trustees, voted to approve continuation of the investment advisory agreement for each Fund.

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory agreement for each Fund, the Board evaluated the nature, extent and quality of services provided to the Funds by the applicable Adviser.

Eaton Vance

Municipal Income Funds

September 30, 2020

Board of Trustees’ Contract Approval — continued

The Board considered each Adviser’s management capabilities and investment processes in light of the types of investments held by each Fund, respectively, including the education, experience and number of investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Funds. In particular, the Board considered, where relevant, the abilities and experience of each Adviser’s investment professionals in analyzing factors such as credit risk, tax efficiency, and special considerations relevant to investing in municipal obligations. The Board considered each Adviser’s municipal bond team, which includes investment professionals and credit specialists who provide services to the applicable Fund. The Board also took into account the resources dedicated to portfolio management and other services, the compensation methods of each Adviser and other factors, including the reputation and resources of the Adviser to recruit and retain highly qualified research, advisory and supervisory investment professionals. In addition, the Board considered the time and attention devoted to the Eaton Vance Funds, including each Fund, 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. The Board also considered the business-related and other risks to which the Advisers or its affiliates may be subject in managing the Funds.

The Board considered the compliance programs of each Adviser and relevant affiliates thereof. The Board considered compliance and reporting matters regarding, among other things, personal trading by investment professionals, disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also considered the responses of each Adviser 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 considered other administrative services provided or overseen by Eaton Vance Management 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, as well as the ability, in many cases, to exchange an investment among different funds without incurring additional sales charges.

After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by each Adviser, taken as a whole, are appropriate and consistent with the terms of the applicable investment advisory agreement.

Fund Performance

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 an appropriate benchmark index, and assessed each Fund’s performance on the basis of total return and current income return. The Board’s review included comparative performance data with respect to each Fund for the one-, three-, five- and ten-year periods ended September 30, 2019.

In this regard, the Board noted each Fund’s performance relative to its peer group and benchmark index for the three-year period, as follows:

Fund	Performance Relative to:
	Median of Peer Group	Benchmark Index
Eaton Vance AMT-Free Municipal Income Fund	Consistent with	Lower
Eaton Vance National Municipal Income Fund	Higher	Higher

The Board considered, among other things, each Adviser’s efforts to generate competitive levels of tax-exempt current income over time through investments that, relative to comparable funds, focus on higher quality municipal bonds with longer maturities. The Board concluded that the performance of each Fund was satisfactory.

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”). As part of its review, the Board considered each Fund’s management fees and total expense ratio for the one-year period ended September 30, 2019, 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 that had an impact on each Fund’s total expense ratio relative to comparable funds.

After considering the foregoing information, and in light of the nature, extent and quality of the services provided by each Adviser, the Board concluded that the management fees charged for advisory and related services are reasonable.

Profitability and “Fall-Out” Benefits

The Board considered the level of profits realized by each Adviser and relevant affiliates thereof in providing investment advisory and administrative services to each Fund 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 each Adviser and its affiliates to third parties in respect of distribution or other services.

Municipal Income Funds

September 30, 2020

Board of Trustees’ Contract Approval — continued

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by each Adviser and its affiliates are deemed not to be excessive.

The Board also considered direct or indirect fall-out benefits received by each Adviser and its affiliates in connection with their respective relationships with the Funds, including the benefits of research services that may be available to each Adviser as a result of securities transactions effected for the Funds and other investment advisory clients.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the applicable Adviser and its affiliates, on the one hand, and each Fund, on the other hand, can expect to realize benefits from economies of scale as the assets of each Fund 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. The Board reviewed data summarizing the increases and decreases in the assets of each Fund 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 each Adviser and its affiliates may have been affected by such increases or decreases. Based upon the foregoing, the Board concluded that each Fund currently shares in the benefits from economies of scale, if any, when they are realized by the Adviser. The Board also concluded that the structure of each advisory fee, which includes breakpoints at several asset levels, will allow each Fund to continue to benefit from any economies of scale in the future.

Liquidity Risk Management Program

The Fund has implemented a written liquidity risk management program (Program) and related procedures to manage its liquidity in accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (Liquidity Rule). The Liquidity Rule defines “liquidity risk” as the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of the remaining investors’ interests in the fund. The Fund’s Board of Trustees/Directors has designated the investment adviser to serve as the administrator of the Program and the related procedures. The administrator has established a Liquidity Risk Management Oversight Committee (Committee) to perform the functions necessary to administer the Program. As part of the Program, the administrator is responsible for identifying illiquid investments and categorizing the relative liquidity of the Fund’s investments in accordance with the Liquidity Rule. Under the Program, the administrator assesses, manages, and periodically reviews the Fund’s liquidity risk, and is responsible for making certain reports to the Fund’s Board of Trustees/Directors and the Securities and Exchange Commission (SEC) regarding the liquidity of the Fund’s investments, and to notify the Board of Trustees/Directors and the SEC of certain liquidity events specified in the Liquidity Rule. The liquidity of the Fund’s portfolio investments is determined based on a number of factors including, but not limited to, relevant market, trading and investment-specific considerations under the Program.

At a meeting of the Fund’s Board of Trustees/Directors, the Committee provided a written report to the Fund’s Board of Trustees/Directors pertaining to the operation, adequacy, and effectiveness of implementation of the Program, as well as the operation of the highly liquid investment minimum (if applicable) for the period December 1, 2018 through December 31, 2019 (Review Period). The Program operated effectively during the Review Period, supporting the administrator’s ability to assess, manage and monitor Fund liquidity risk, including during periods of market volatility and net redemptions. During the Review Period, the Fund met redemption requests on a timely basis.

There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

(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”).

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.
