Semiannual Report

March 31, 2024

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

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.

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. Furthermore, returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the redemption of Fund shares. 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.

Fund Profile

Asset Allocation (% of total investments)

Credit Quality (% of bond holdings)¹

Footnotes:

For purposes of the Fund’s rating restrictions, ratings are based on Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings (“S&P”) or Fitch Ratings (“Fitch”), or Kroll for securitized debt instruments only (such as asset-backed securities and mortgage-backed securities) 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, Fitch or Kroll (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.

Endnotes and Additional Disclosures

¹	Bloomberg 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.
²	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 November 5, 2020, Class C shares automatically convert to Class A shares eight years after purchase. The average annual total returns listed for Class C reflect conversion to Class A shares after eight years. Prior to November 5, 2020, Class C shares automatically converted to Class A shares ten years after purchase. Performance prior to the inception date of a class may be linked to the performance of an older class of the Fund. This linked performance is adjusted for any applicable sales charge, but is not adjusted for class expense differences. If adjusted for such differences, the performance would be different. The performance of Class R6 is linked to Class I. Performance presented in the Financial Highlights included in the financial statements is not linked. 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.
³	Source: Fund prospectus. Net expense ratios reflect a contractual expense reimbursement that continues through 2/1/25. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report. Performance reflects expenses waived and/or reimbursed, if applicable. Without such waivers and/or reimbursements, performance would have been lower.

Fund profile subject to change due to active management.

Fund Expenses

Example

As a Fund shareholder, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchases; 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 (October 1, 2023 to March 31, 2024).

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). 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 (10/1/23)	Ending Account Value (3/31/24)	Expenses Paid During Period* (10/1/23 – 3/31/24)	Annualized Expense Ratio
Actual
Class A	$1,000.00	$1,075.70	$3.89**	0.75%
Class C	$1,000.00	$1,071.80	$7.77**	1.50%
Class I	$1,000.00	$1,077.10	$2.60**	0.50%
Class R6	$1,000.00	$1,077.40	$2.18**	0.42%

Hypothetical
(5% return per year before expenses)
Class A	$1,000.00	$1,021.25	$3.79**	0.75%
Class C	$1,000.00	$1,017.50	$7.57**	1.50%
Class I	$1,000.00	$1,022.50	$2.53**	0.50%
Class R6	$1,000.00	$1,022.90	$2.12**	0.42%

*	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 September 30, 2023.
**	Absent an allocation of certain expenses to affiliate(s), expenses would be higher.

1 Significant Accounting Policies

Eaton Vance Total Return 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 four 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 November 5, 2020, Class C shares automatically convert to Class A shares eight years after their purchase as described in the Fund’s prospectus. Class I and Class R6
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. Sub-accounting, recordkeeping and similar administrative fees payable to financial intermediaries, which are a component of transfer and dividend disbursing agent fees on the Statement of Operations, are not allocated to Class R6 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 National Market System 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. U.S. exchange-traded options are valued at the mean between the bid and ask prices at valuation time as reported by the Options Price Reporting Authority. 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. Swaps are normally valued using valuations provided by a third party pricing service. Such pricing service valuations are based on the present value of fixed and projected floating rate cash flows over the term of the swap contract, and in the case of credit default swaps, based on credit spread quotations obtained from broker/dealers and expected default recovery rates determined by the pricing service using proprietary models. Future cash flows on swaps are discounted to their present value using swap rates provided by electronic data services or by broker/dealers.

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.

Other. Investments in management investment companies (including money market funds) that do not trade on an exchange are valued at the net asset value as of the close of each business day.

Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Trustees have designated the Fund’s investment adviser as its valuation designee. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued by the investment adviser, as valuation designee, at fair value using methods that most fairly reflect the security’s “fair value”, which is the amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual

restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies or entities, quotations or relevant information obtained from broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial statements, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

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

C Income—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 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 and Other 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 March 31, 2024, 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 Futures Contracts—Upon entering into a 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 futures contracts. Should market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the 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

Table of Contents

Eaton Vance

Total Return Bond Fund

March 31, 2024

Notes to Financial Statements (Unaudited) — continued

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 Purchased Options—Upon the purchase of a call or put option, the premium paid by the Fund is included in the Statement of Assets and Liabilities as an investment. The amount of the investment is subsequently marked-to-market to reflect the current market value of the option purchased, in accordance with the Fund’s policies on investment valuations discussed above. Premiums paid for purchasing options that expire are treated as realized losses.
Premiums paid for purchasing options that are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain or loss. An option on a futures contract gives the holder the right to enter into a specified futures contract. As the purchaser of an index option, the Fund has the right to receive a cash payment equal to any depreciation in the value of the index below the exercise price of the option (in the case of a put) or equal to any appreciation in the value of the index over the exercise price of the option (in the case of a call) as of the valuation date of the option. The risk associated with purchasing options is limited to the premium originally paid. Purchased options traded over-the-counter involve risk that the issuer or counterparty will fail to perform its contractual obligations.

L Credit Default Swaps—When the Fund is the buyer of a credit default swap contract, the Fund is entitled to receive the par (or other agreed-upon) value of a referenced debt obligation (or basket of debt obligations) from the counterparty to the contract if a credit event by a third party, such as a U.S. or foreign corporate issuer or sovereign issuer, on the debt obligation occurs. In return, the Fund pays the counterparty a periodic stream of payments over the term of the contract provided that no credit event has occurred. If no credit event occurs, the Fund would have spent the stream of payments and received no proceeds from the contract. When the Fund is the seller of a credit default swap contract, it receives the stream of payments, but is obligated to pay to the buyer of the protection an amount up to the notional amount of the swap and in certain instances take delivery of securities of the reference entity upon the occurrence of a credit event, as defined under the terms of that particular swap agreement. Credit events are contract specific but may include bankruptcy, failure to pay, restructuring, obligation acceleration and repudiation/moratorium. If the Fund is a seller of protection and a credit event occurs, the maximum potential amount of future payments that the Fund could be required to make would be an amount equal to the notional amount of the agreement. This potential amount would be partially offset by any recovery value of the respective referenced obligation, or net amount received from the settlement of a buy protection credit default swap agreement entered into by the Fund for the same referenced obligation. As the seller, the Fund may create economic leverage to its portfolio because, in addition to its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. The interest fee paid or received on the swap contract, which is based on a specified interest rate on a fixed notional amount, is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as realized gain upon receipt or realized loss upon payment. The Fund also records an increase or decrease to unrealized appreciation (depreciation) in an amount equal to the daily valuation. For centrally cleared swaps, the daily change in valuation is recorded as a receivable or payable for variation margin and settled in cash with the CCP daily. All upfront payments and receipts, if any, are amortized over the life of the swap contract as realized gains or losses. Those upfront payments or receipts for non-centrally cleared swaps are recorded as other assets or other liabilities, respectively, net of amortization. For financial reporting purposes, unamortized upfront payments or receipts, if any, are netted with unrealized appreciation or depreciation on swap contracts to determine the market value of swaps. These transactions involve certain risks, including the risk that the seller may be unable to fulfill the transaction. In the case of centrally cleared swaps, counterparty risk is minimal due to protections provided by the CCP.

M When-Issued Securities and Delayed Delivery Transactions—The Fund may purchase securities on a delayed delivery, when-issued or forward commitment basis, including TBA (To Be Announced) securities. 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. Securities purchased on a delayed delivery, when-issued or forward commitment basis are marked-to-market daily and begin earning interest on settlement date. Such security purchases are subject to the risk that when delivered they will be worth less than the agreed upon payment price. Losses may also arise if the counterparty does not perform under the contract. A forward purchase commitment may also be closed by entering into an offsetting commitment. If an offsetting commitment is entered into, the Fund will realize a gain or loss on investments based on the price established when the Fund entered into the commitment.

N Interim Financial Statements—The interim financial statements relating to March 31, 2024 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2 Distributions to Shareholders and Income Tax Information

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.

Total Return Bond Fund

March 31, 2024

Notes to Financial Statements (Unaudited) — continued

At September 30, 2023, the Fund, for federal income tax purposes, had deferred capital losses of $80,395,994 which would reduce the 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 Fund of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Fund’s next taxable year, can be carried forward for an unlimited period, and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at September 30, 2023, $55,894,991 are short-term and $24,501,003 are long-term.

Additionally, at September 30, 2023, the Fund had a late year ordinary loss of $795,057 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 March 31, 2024, as determined on a federal income tax basis, were as follows:

Aggregate cost	$1,690,518,866
Gross unrealized appreciation	$ 22,263,926
Gross unrealized depreciation	(55,394,692)
Net unrealized depreciation	$ (33,130,766)

3 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Boston Management and Research (BMR), an indirect, wholly-owned subsidiary of Morgan Stanley, as compensation for investment advisory services rendered to the Fund. The fee is computed at an annual rate as a percentage of average daily net assets as follows and is payable monthly:

Average Daily Net Assets	Annual Fee Rate
Up to $1 billion	0.450%
$1 billion but less than $2.5 billion	0.425%
$2.5 billion but less than $5 billion	0.410%
Over $5 billion	0.400%

For the six months ended March 31, 2024, the investment adviser fee amounted to $2,844,995 or 0.44% (annualized) of the Fund’s average daily net assets.

The Fund may invest in a money market fund, the Institutional Class of the Morgan Stanley Institutional Liquidity Funds - Government Portfolio (the “Liquidity Fund”), an open-end management investment company managed by Morgan Stanley Investment Management Inc., a wholly-owned subsidiary of Morgan Stanley. The investment adviser fee paid by the Fund is reduced by an amount equal to its pro rata share of the advisory and administration fees paid by the Fund due to its investment in the Liquidity Fund. For the six months ended March 31, 2024, the investment adviser fee paid was reduced by $42,748 relating to the Fund’s investment in the Liquidity Fund.

Eaton Vance Management (EVM), an affiliate of BMR and an indirect, wholly-owned subsidiary of Morgan Stanley, has agreed to reimburse the Fund’s expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only and excluding expenses such as brokerage commissions, acquired fund fees and expenses of unaffiliated funds, borrowing costs, taxes or litigation expenses) exceed 0.74%, 1.49%, 0.49% and 0.43% of the Fund’s average daily net assets for Class A, Class C, Class I and Class R6, respectively. This agreement may be changed or terminated after February 1, 2025. Pursuant to this agreement, EVM was allocated $596,818 of the Fund’s operating expenses for the six months ended March 31, 2024.

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 six months ended March 31, 2024, EVM earned $4,548 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 $9,598 as its portion of the sales charge on sales of Class A shares for the six months ended March 31, 2024. 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).

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. 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 six months ended March 31, 2024 amounted to $114,067 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 six months ended March 31, 2024, the Fund paid or accrued to EVD $116,399 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 six months ended March 31, 2024 amounted to $38,799 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 0.75% CDSC if redeemed within 12 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 six months ended March 31, 2024, the Fund was informed that EVD received $1,686 and $1,508 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, TBA transactions, and principal repayments on Senior Loans, for the six months ended March 31, 2024 were as follows:

	Purchases	Sales
Investments (non-U.S. Government)	$ 734,713,767	$ 531,263,628

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 forward foreign currency exchange contracts, futures contracts and swap 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 March 31, 2024 is included in the Portfolio of Investments. At March 31, 2024, 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:

Total Return Bond Fund

March 31, 2024

Notes to Financial Statements (Unaudited) — continued

Credit Risk: The Fund enters into credit default swap contracts to manage certain investment risks and/or to enhance total return or as a substitute for the purchase or sale of securities.

Interest Rate Risk: The Fund enters into interest rate futures contracts and options on 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 over-the-counter (OTC) derivatives 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 payment by the Fund for those derivatives in a liability position. At March 31, 2024, the fair value of derivatives with credit-related contingent features in a net liability position was $229,895. At March 31, 2024, there were no assets pledged by the Fund for such liability.

The 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 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 March 31, 2024 was as follows:

		Fair Value
Risk	Derivative	Asset Derivative	Liability Derivative
Foreign Exchange	Forward foreign currency exchange contracts	$ 12,546⁽¹⁾	$ (229,895)⁽²⁾

The average notional cost of futures contracts and average notional amounts of other derivative contracts outstanding during the six months ended March 31, 2024, 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*	Swap Contracts
$409,680,000	$896,000	$18,482,000	$1,571,000

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

The average number of purchased options contracts outstanding during the six months ended March 31, 2024, which is indicative of the volume of this derivative type, was 125 contracts.

9 Line of Credit

The Fund participates with other portfolios and funds managed by EVM and its affiliates in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 22, 2024. In connection with the renewal of the agreement on October 24, 2023, the borrowing limit was decreased from $725 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 Secured Overnight Financing Rate (SOFR) 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. In connection with the renewal of the agreement in October 2023, an arrangement fee of $150,000 was incurred that was allocated to the participating portfolios and funds. 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 six months ended March 31, 2024.

10 Affiliated Investments

At March 31, 2024, the value of the Fund's investment in issuers and funds that may be deemed to be affiliated was $122,865,614, which represents 8.1% of the Fund's net assets. Transactions in such investments by the Fund for the six months ended March 31, 2024 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 March 31, 2024, the hierarchy of inputs used in valuing the Fund's investments and open derivative instruments, which are carried at fair value, were as follows:

Asset Description	Level 1	Level 2	Level 3*	Total
Affiliated Investment Funds	$ 10,232,773	$ —	$ —	$ 10,232,773

12 Risks and Uncertainties

Risks Associated with Foreign Investments

Foreign investments can be adversely affected by political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country. There may be less publicly available information about foreign issuers because they may not be subject to reporting practices, requirements or regulations comparable to those to which United States companies are subject. Foreign markets may be smaller, less liquid and more volatile than the major markets in the United States. Trading in foreign markets typically involves higher expense than trading in the United States. The Fund may have difficulties enforcing its legal or contractual rights in a foreign country. Securities that trade or are denominated in currencies other than the U.S. dollar may be adversely affected by fluctuations in currency exchange rates.

Economic data as reported by sovereign entities may be delayed, inaccurate or fraudulent. In the event of a default by a sovereign entity, there are typically no assets to be seized or cash flows to be attached. Furthermore, the willingness or ability of a sovereign entity to restructure defaulted debt may be limited. Therefore, losses on sovereign defaults may far exceed the losses from the default of a similarly rated U.S. debt issuer.

IMPORTANT NOTICES

Delivery of Shareholder Documents. The Securities and Exchange Commission (SEC) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders. Eaton Vance, or your financial intermediary, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial intermediary, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-262-1122, or contact your financial intermediary. Your instructions that householding not apply to delivery of your Eaton Vance documents will typically be effective within 30 days of receipt by Eaton Vance or your financial intermediary.

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

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

Tailored Shareholder Reports. Effective January 24, 2023, the SEC adopted rule and form amendments to require open-end mutual funds and ETFs to transmit concise and visually engaging streamlined annual and semiannual reports to shareholders that highlight key information. Other information, including financial statements, will no longer appear in a streamlined shareholder report but must be available online, delivered free of charge upon request, and filed on a semiannual basis on Form N-CSR. The rule and form amendments have a compliance date of July 24, 2024. At this time, management is evaluating the impact of these amendments on the shareholder reports for the Eaton Vance Funds.

The Commodity Futures Trading Commission (“CFTC”) has adopted regulations that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. 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.

Footnotes:

For purposes of the Fund’s rating restrictions, 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.

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

Endnotes and Additional Disclosures

¹	Bloomberg 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.
²	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 November 5, 2020, Class C shares automatically convert to Class A shares eight years after purchase. The average annual total returns listed for Class C reflect conversion to Class A shares after eight years. Prior to November 5, 2020, Class C shares automatically converted to Class A shares ten years after purchase.
³	Source: Fund prospectus. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report.
⁴	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.
⁵	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.

Fund Expenses

Example

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). 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. Each Fund’s 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 November 5, 2020, Class C shares 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.

Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Trustees have designated a Fund’s investment adviser as its valuation designee. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued by the investment adviser, as valuation designee, at fair value using methods that most fairly reflect 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 companies or entities, quotations or relevant information obtained from broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial statements, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B Investment Transactions 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 March 31, 2024, 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 10) at March 31, 2024. 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 March 31, 2024, 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	$4,007,324	$54,916,341
Interest Rate or Range of Interest Rates (%)	3.67	3.64 - 3.68
Collateral for Floating Rate Notes Outstanding	$5,463,760	$74,340,045

For the six months ended March 31, 2024, the Funds’ average settled Floating Rate Notes outstanding and the average interest rate (annualized) including fees were as follows:

	AMT-Free Fund	National Fund
Average Floating Rate Notes Outstanding	$5,372,951	$54,800,000
Average Interest Rate	4.17%	4.02%

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 March 31, 2024.

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.

Notes to Financial Statements (Unaudited) — continued

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. Effective August 19, 2022, the Funds began operating under Rule 18f-4 under the 1940 Act, which, among other things, governs the use of derivative investments and certain financing transactions by registered investment companies. As of the date of this report, consistent with Rule 18f-4, the Funds have elected to treat their investments in residual interest bonds, along with similar financing transactions, as derivatives transactions subject to the Funds' value-at-risk (VaR)-based limits on leverage risk. The Funds may change this election (and elect to treat these investments and other similar financing transactions like bank borrowings subject to the asset coverage requirements of Section 18 of the 1940 Act) at any time. Residual interest bonds held by the Funds are securities exempt from registration under Rule 144A of the Securities Act of 1933.

I Futures Contracts—Upon entering into a futures contract, a 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 futures contracts. Should market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the 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 When-Issued Securities and Delayed Delivery Transactions—The Funds may purchase 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. Such security purchases are subject to the risk that when delivered they will be worth less than the agreed upon payment price. Losses may also arise if the counterparty does not perform under the contract.

K Interim Financial Statements—The interim financial statements relating to March 31, 2024 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Funds' management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2 Distributions to Shareholders and Income Tax Information

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.

At September 30, 2023, 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	$26,756,879	$294,364,229
Long-term	$23,706,355	$123,914,103

3 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Eaton Vance Management (EVM), an indirect, wholly-owned subsidiary of Morgan Stanley, for AMT-Free Fund and Boston Management and Research (BMR), an affiliate of EVM, for National Fund as compensation for management and investment advisory services rendered to each Fund. The investment adviser fee is based upon a percentage of total daily net assets plus a percentage of total daily gross income (i.e., income other than gains from the sale of securities) as follows and is payable monthly:

Total Daily Net Assets	Annual Asset Rate	Daily Income Rate
Up to $500 million	0.300%	3.000%
$500 million but less than $1 billion	0.275%	2.750%
$1 billion but less than $1.5 billion	0.250%	2.500%
$1.5 billion but less than $2 billion	0.225%	2.250%
$2 billion but less than $3 billion	0.200%	2.000%
$3 billion and over	0.175%	1.750%

For the six months ended March 31, 2024, 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	$481,998	$6,399,231
Effective Annual Rate	0.43%	0.33%

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. Morgan Stanley affiliated broker-dealers, which may be deemed to be affiliates of BMR, EVM and EVD, also received a portion of the sales charge on sales of Class A shares. 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 and Morgan Stanley affiliated broker-dealers for the six months ended March 31, 2024 were as follows:

	AMT-Free Fund	National Fund
EVM's Sub-Transfer Agent Fees	$5,388	$82,380
EVD's Class A Sales Charges	$ 812	$18,616
Morgan Stanley affiliated broker-dealers’ Class A Sales Charges	$ —	$ 6,534

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. 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 six months ended March 31, 2024 for Class A shares amounted to the following:

	AMT-Free Fund	National Fund
Class A Distribution and Service Fees	$130,520	$1,451,765

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 Fund. For the six months ended March 31, 2024, the Funds paid or accrued to EVD the following distribution fees:

	AMT-Free Fund	National Fund
Class C Distribution Fees	$12,440	$169,087

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 six months ended March 31, 2024 amounted to the following:

	AMT-Free Fund	National Fund
Class C Service Fees	$4,147	$56,362

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 0.75% CDSC if redeemed within 12 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 six months ended March 31, 2024, the Funds were informed that EVD received the following amounts of CDSCs paid by Class A and Class C shareholders:

	AMT-Free Fund	National Fund
Class A	$ — ⁽¹⁾	$ 125
Class C	$ —	$1,071

⁽¹⁾	Amount is less than $100.

7 Shares of Beneficial Interest

Each 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 Funds) and classes. Transactions in Fund shares, including direct exchanges pursuant to share class conversions, were as follows:

8 Financial Instruments

The Funds may trade in financial instruments with off-balance sheet risk in the normal course of their investing activities. These financial instruments may include futures 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 a 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. At March 31, 2024, there were no obligations outstanding under these financial instruments.

Each Fund is subject to interest rate risk in the normal course of pursuing its investment objective. Because the Funds hold fixed-rate bonds, the value of these bonds may decrease if interest rates rise. During the six months ended March 31, 2024, National Fund entered into U.S. Treasury futures contracts to hedge against changes in interest rates.

The effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) on the Statement of Operations and whose primary underlying risk exposure is interest rate risk for the six months ended March 31, 2024 was as follows:

	National Fund
Realized Gain (Loss) on Derivatives Recognized in Income	$ 1,196,126⁽¹⁾
Change in Unrealized Appreciation (Depreciation) on Derivatives Recognized in Income	$(4,363,160) ⁽²⁾

⁽¹⁾	Statement of Operations location: Net realized gain (loss): Futures contracts.
⁽²⁾	Statement of Operations location: Change in unrealized appreciation (depreciation): Futures contracts.

The average notional cost of futures contracts outstanding during the six months ended March 31, 2024, which is indicative of the volume of this derivative type, was approximately as follows:

	National Fund
Average Notional Cost:
Futures Contracts — Short	$31,317,000

9 Line of Credit

The Funds participate with other portfolios and funds managed by EVM and its affiliates in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 22, 2024. In connection with the renewal of the agreement on October 24, 2023, the borrowing limit was decreased from $725 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 Secured Overnight Financing Rate (SOFR) 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. In connection with the renewal of the agreement in October 2023, an arrangement fee of $150,000 was incurred that was allocated to the participating portfolios and funds. 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 six months ended March 31, 2024.
