Short Duration Diversified Income Fund (EVG)

Semiannual Report

April 30, 2021

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

Asset Allocation (% of total leveraged assets)⁶

See Endnotes and Additional Disclosures in this report.

Past performance is no guarantee of future results. Returns are historical and are calculated net of management fees and other expenses by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributions reinvested in accordance with the Fund’s Dividend Reinvestment Plan. Performance at market price will differ from performance at NAV due to variations in the Fund’s market price versus NAV, which may reflect factors such as fluctuations in supply and demand for Fund shares, changes in Fund distributions, shifting market expectations for the Fund’s future returns and distribution rates, and other considerations affecting the trading prices of closed-end funds. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance for periods less than or equal to one year is cumulative. Performance is for the stated time period only; due to market volatility, current Fund performance may be lower or higher than the quoted return. For performance as of the most recent month-end, please refer to eatonvance.com.

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  Performance results reflect the effects of leverage. Absent an expense waiver by the investment adviser, if applicable, the returns would be lower.

³  The shares of the Fund often trade at a discount or premium to their net asset value. The discount or premium may vary over time and may be higher or lower than what is quoted in this report. For up-to-date premium/discount information, please refer to https://funds.eatonvance.com/closed-end-fund-prices.php.

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 or market price at the end of the period. The Fund’s distributions may be comprised of amounts characterized for federal income tax purposes as qualified and non-qualified ordinary dividends, capital gains and nondividend distributions, also known as return of capital. The Fund will determine the federal income tax character of distributions paid to a shareholder after the end of the calendar year. This is reported on the IRS form 1099-DIV and provided to the shareholder shortly after each year-end. For information about the tax character of distributions made in prior calendar years, please refer to Performance-Tax Character of Distributions on the Fund’s webpage available at eatonvance.com. The Fund’s distributions are determined by the investment adviser. Fund distributions may be affected by numerous factors including changes in Fund performance, the cost of financing for leverage, portfolio holdings, realized and projected returns, and other factors. As portfolio and market conditions change, the rate of distributions paid by the Fund could change.

⁵  The Fund employs leverage through derivatives and borrowings. Total leverage is shown as a percentage of the Fund’s aggregate net assets plus the absolute notional value of long and short derivatives and borrowings outstanding. Use of leverage creates an opportunity for income, but creates risks including greater price volatility. The cost of borrowings rises and falls with changes in short-term interest rates. The Fund may be required to maintain prescribed asset coverage for its leverage and may be required to reduce its leverage at an inopportune time.

⁶  Total leveraged assets include all assets of the Fund (including those acquired with financial leverage) and derivatives held by the Fund. Asset Allocation as a percentage of the Fund’s net assets amounted to 139.8%. Please refer to the definition of total leveraged assets within the Notes to Financial Statements included herein.

⁽⁵⁾  Principal only security that entitles the holder to receive only principal payments on the underlying mortgages.

⁽⁶⁾  Principal amount is less than $500.

⁽⁷⁾  Weighted average fixed-rate coupon that changes/updates monthly. Rate shown is the rate at April 30, 2021.

⁽⁸⁾  Represents an investment in an issuer that may be deemed to be an affiliate effective March 1, 2021 (see Note 8).

⁽⁹⁾  Adjustable rate mortgage security whose interest rate generally adjusts monthly based on a weighted average of interest rates on the underlying mortgages. The coupon rate may not reflect the applicable index value as interest rates on the underlying mortgages may adjust on various dates and at various intervals and may be subject to lifetime ceilings and lifetime floors and lookback periods. Rate shown is the coupon rate at April 30, 2021.

⁽¹⁰⁾  TBA (To Be Announced) securities are purchased on a forward commitment basis with an approximate principal amount and maturity date. The actual principal amount and maturity date are determined upon settlement.

⁽¹¹⁾  Amount is less than 0.05%.

⁽¹²⁾  Security was acquired in connection with a restructuring of a Senior Loan and may be subject to restrictions on resale.

⁽¹³⁾  Non-income producing security.

⁽¹⁴⁾  For fair value measurement disclosure purposes, security is categorized as Level 3 (see Note 9).

⁽¹⁵⁾  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 April 30, 2021, the aggregate value of these securities is $33,514,385 or 13.6% of the Fund’s net assets.

⁽¹⁶⁾  Represents a payment-in-kind security which may pay interest in additional principal at the issuer’s discretion.

⁽¹⁷⁾  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.

⁽¹⁸⁾  The stated interest rate represents the weighted average interest rate at April 30, 2021 of contracts within the senior loan facility. Interest rates on contracts are primarily redetermined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period.

⁽¹⁹⁾  This Senior Loan will settle after April 30, 2021, at which time the interest rate will be determined.

⁽²⁰⁾  Unfunded or partially unfunded loan commitments. The stated interest rate reflects the weighted average of the reference rate and spread for the funded portion, if any, and the commitment fees on the portion of the loan that is unfunded. At April 30, 2021, the total value of unfunded loan commitments is $160,735. See Note 1F for description.

⁽²¹⁾  Issuer is in default with respect to interest and/or principal payments. For a variable rate security, interest rate has been adjusted to reflect non-accrual status.

⁽²²⁾  Step coupon security. Interest rate represents the rate in effect at April 30, 2021.

⁽²³⁾  Amounts payable in respect of the security are contingent upon and determined by reference to Ukraine’s GDP and Real GDP Growth Rate. Principal amount represents the notional amount used to calculate payments due to the security holder and does not represent an entitlement for payment.

⁽²⁴⁾  Loan is subject to scheduled mandatory prepayments. Maturity date shown reflects the final maturity date.

⁽²⁵⁾  Security (or a portion thereof) has been pledged to cover collateral requirements on open derivative contracts.

⁽²⁶⁾  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 April 30, 2021.

* If the Fund is the seller of credit protection, the notional amount is the maximum potential amount of future payments the Fund could be required to make if a credit event, as defined in the credit default swap agreement, were to occur. At April 30, 2021, such maximum potential amount for all open credit default swaps in which the Fund is the seller was $47,580,000.

** The contract annual fixed rate represents the fixed rate of interest received by the Fund (as a seller of protection) on the notional amount of the credit default swap contract.

*** Current market annual fixed rates, utilized in determining the net unrealized appreciation or depreciation as of period end, serve as an indicator of the market’s perception of the current status of the payment/performance risk associated with the credit derivative. The current market annual fixed rate of a particular reference entity reflects the cost, as quoted by the pricing vendor, of selling protection against default of that entity as of period end and may include upfront payments required to be made to enter into the agreement. The higher the fixed rate, the greater the market perceived risk of a credit event involving the reference entity. A rate identified as “Defaulted” indicates a credit event has occurred for the reference entity.

⁽¹⁾  Upfront payment is exchanged with the counterparty as a result of the standardized trading coupon.

Notes to Financial Statements (Unaudited)

1  Significant Accounting Policies

Eaton Vance Short Duration Diversified Income Fund (the Fund) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, closed-end management investment company. The Fund’s investment objective is to provide a high level of current income. The Fund may, as a secondary objective, also seek capital appreciation to the extent consistent with its primary goal of high current income.

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.

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. Other Senior Loans are valued at fair value by the investment adviser under procedures approved by the Trustees. In fair valuing a Senior Loan, the investment adviser utilizes one or more of the valuation techniques described in (i) through (iii) below to assess the likelihood that the borrower will make a full repayment of the loan underlying such Senior Loan relative to yields on other Senior Loans issued by companies of comparable credit quality. If the investment adviser believes that there is a reasonable likelihood of full repayment, the investment adviser will determine fair value using a matrix pricing approach that considers the yield on the Senior Loan. If the investment adviser believes there is not a reasonable likelihood of full repayment, the investment adviser will determine fair value using analyses that include, but are not limited to: (i) a comparison of the value of the borrower’s outstanding equity and debt to that of comparable public companies; (ii) a discounted cash flow analysis; or (iii) when the investment adviser believes it is likely that a borrower will be liquidated or sold, an analysis of the terms of such liquidation or sale. In certain cases, the investment adviser will use a combination of analytical methods to determine fair value, such as when only a portion of a borrower’s assets are likely to be sold. In conducting its assessment and analyses for purposes of determining fair value of a Senior Loan, the investment adviser will use its discretion and judgment in considering and appraising relevant factors. Fair value determinations are made by the portfolio managers of the Fund based on information available to such managers. The portfolio managers of other funds managed by the investment adviser that invest in Senior Loans may not possess the same information about a Senior Loan borrower as the portfolio managers of the Fund. At times, the fair value of a Senior Loan determined by the portfolio managers of other funds managed by the investment adviser that invest in Senior Loans may vary from the fair value of the same Senior Loan determined by the portfolio managers of the Fund. The fair value of each Senior Loan is periodically reviewed and approved by the investment adviser’s Valuation Committee and by the Trustees based upon procedures approved by the Trustees. Junior Loans (i.e., subordinated loans and second lien loans) are valued in the same manner as Senior Loans.

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.

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. 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. The daily valuation of exchange-traded foreign securities generally is determined as of the close of trading on the principal exchange on which such securities trade. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the New York Stock Exchange.

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

on the valuation day. Cash Reserves Fund generally values its investment securities based on available market quotations provided by a third party pricing service.

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

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

C  Income — 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, if any, have been provided for in accordance with the Fund’s understanding of the applicable countries’ tax rules and rates.

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

As of April 30, 2021, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Fund files a U.S. federal income tax return annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

E  Foreign Currency Translation — Investment valuations, other assets, and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investment securities and income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates in effect on the respective dates of such transactions. Recognized gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net realized gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

F  Unfunded Loan Commitments — The Fund may enter into certain loan agreements all or a portion of which may be unfunded. The Fund is obligated to fund these commitments at the borrower’s discretion. These commitments, in any, are disclosed in the accompanying Portfolio of Investments. At April 30, 2021, the Fund had sufficient cash and/or securities to cover these commitments.

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

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

35

Eaton Vance

Short Duration Diversified Income Fund

April 30, 2021

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. While forward foreign currency exchange contracts are privately negotiated agreements between the Fund and a counterparty, certain contracts may be “centrally cleared”, whereby all payments made or received by the Fund pursuant to the contract are with a central clearing party (CCP) rather than the original counterparty. The CCP guarantees the performance of the original parties to the contract. Upon entering into centrally cleared contracts, the Fund is required to deposit with the CCP, either in cash or securities, an amount of initial margin determined by the CCP, which is subject to adjustment. For centrally cleared contracts, the daily change in valuation is recorded as a receivable or payable for variation margin and settled in cash with the CCP daily. Risks may arise upon entering forward foreign currency exchange 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. In the case of centrally cleared contracts, counterparty risk is minimal due to protections provided by the CCP.

K  Interest Rate Swaps — Pursuant to interest rate swap agreements, the Fund either makes floating-rate payments to the counterparty (or CCP in the case of centrally cleared swaps) based on a benchmark interest rate in exchange for fixed-rate payments or the Fund makes fixed-rate payments to the counterparty (or CCP in the case of a centrally cleared swap) in exchange for payments on a floating benchmark interest rate. Payments received or made, including amortization of upfront payments/receipts, are recorded as realized gains or losses. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains or losses. 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. The value of the swap is determined by changes in the relationship between two rates of interest. The Fund is exposed to credit loss in the event of non-performance by the swap counterparty. In the case of centrally cleared swaps, counterparty risk is minimal due to protections provided by the CCP. Risk may also arise from movements in interest rates.

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 (or CCP in the case of a centrally cleared swap) 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 as presented in Notes 6 and 9. The Fund segregates assets in the form of cash or liquid securities in an amount equal to the notional amount of the credit default swaps of which it is the seller. The Fund segregates assets in the form of cash or liquid securities in an amount equal to any unrealized depreciation of the credit default swaps of which it is the buyer, marked-to-market on a daily basis. 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 or sell 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. The Fund maintains 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, when-issued or forward commitment 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. A forward purchase or sale commitment may be closed by entering into an offsetting commitment or delivery of securities. The Fund will realize a gain or loss on investments based on the price established when the Fund entered into the commitment.

N  Stripped Mortgage-Backed Securities — The Fund may invest in Interest Only (IO) and Principal Only (PO) securities, a form of stripped mortgage-backed securities, whereby the IO security receives all the interest and the PO security receives all the principal on a pool of mortgage assets. The yield to maturity on an IO security is extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on the yield to maturity from these securities. If the underlying mortgages experience greater than anticipated prepayments of principal, the Fund may fail to recoup its initial investment in an IO security. The market value of IO and PO securities can be unusually volatile due to changes in interest rates.

O  Interim Financial Statements — The interim financial statements relating to April 30, 2021 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2  Distributions to Shareholders and Income Tax Information

The Fund intends to make monthly distributions to shareholders and at least one distribution annually of all or substantially all of its net realized capital gains. In its distributions, the Fund intends to include amounts attributable to the imputed interest on foreign currency exposures through long and short positions in forward currency exchange contracts (represented by the difference between the foreign currency spot rate and the foreign currency forward rate) and the imputed interest derived from certain other derivative positions. Distributions are recorded on the ex-dividend date. Distributions to shareholders are determined in accordance with income tax regulations, which may differ from U.S. GAAP. As required by U.S. GAAP, only distributions in excess of tax basis earnings and profits are reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income. In certain circumstances, a portion of distributions to shareholders may include a return of capital component. For the six months ended April 30, 2021, the amount of distributions estimated to be a tax return of capital was approximately $2,492,000. The final determination of tax characteristics of the Fund’s distributions will occur at the end of the year, at which time it will be reported to the shareholders.

At October 31, 2020, the Fund, for federal income tax purposes, had deferred capital losses of $10,474,940 which would reduce its taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus would reduce the amount of distributions to shareholders, which would otherwise be necessary to relieve the Fund of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Fund’s next taxable year, 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 October 31, 2020, $5,576,571 are short-term and $4,898,369 are long-term.

The cost and unrealized appreciation (depreciation) of investments, including open derivative contracts, of the Fund at April 30, 2021, as determined on a federal income tax basis, were as follows:

Aggregate cost	$	293,948,059
Gross unrealized appreciation	$	8,183,709
Gross unrealized depreciation		(18,627,050	)
Net unrealized depreciation	$	(10,443,341	)

3  Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by EVM as compensation for investment advisory services rendered to the Fund. On March 1, 2021, Morgan Stanley acquired Eaton Vance Corp. (the “Transaction”) and EVM became an indirect, wholly-owned subsidiary of Morgan Stanley. In connection with the closing of the Transaction, the Fund entered into an interim investment advisory agreement (the “Interim Agreement”) with EVM, which took effect on March 1, 2021. The Interim Agreement allows EVM to continue to manage the Fund for up to an additional 150 days following the Transaction to provide more time for further proxy solicitation in connection with shareholder approval of a new investment advisory agreement (the “New Agreement”). Pursuant to the Interim Agreement (and the Fund’s investment advisory agreement with EVM in effect prior to March 1, 2021), the fee is computed at an annual rate of 0.75% of the Fund’s average daily total leveraged assets, subject to the limitation described below, and is payable monthly. Total leveraged assets as referred to herein represent net assets plus liabilities or obligations attributable to investment leverage and the notional value of long and short forward foreign currency contracts, futures contracts and swaps held by the Fund. The notional value of a contract for purposes of calculating total leveraged assets is the stated dollar value of the underlying reference instrument at the time the derivative position is entered into and remains constant throughout the life of the derivative contract. However, the derivative contracts are marked-to-market daily and any unrealized appreciation or depreciation is reflected in the Fund’s net assets. When the Fund holds both long and short forward currency contracts in the same foreign currency, the offsetting positions are netted for purposes of determining total leveraged assets. When the Fund holds other long and short positions in foreign obligations in a given country denominated in the same currency, total leveraged assets are calculated by excluding the smaller of the long or short position.

The Interim Agreement (and investment advisory agreement in effect prior to March 1, 2021) provides that if investment leverage exceeds 40% of the Fund’s total leveraged assets, EVM will not receive a management fee on total leveraged assets in excess of this amount. As of April 30, 2021, the Fund’s investment leverage was 29% of its total leveraged assets. For the six months ended April 30, 2021, the Fund’s investment adviser fee amounted to $1,358,481 or 0.75% (annualized) of the Fund’s average daily total leveraged assets and 1.11% (annualized) of the Fund’s average daily net assets. The Fund may invest its cash in Cash Reserves Fund. EVM does not currently receive a fee for advisory services provided to Cash Reserves Fund. EVM also serves as administrator of the Fund, but receives no compensation.

Notes to Financial Statements (Unaudited) — continued

The New Agreement was approved by Fund shareholders on May 7, 2021 (see Note 11).

Trustees and officers of the Fund who are members of EVM’s organization receive remuneration for their services to the Fund out of the investment adviser fee. Trustees of the Fund who are not affiliated with EVM may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended April 30, 2021, no significant amounts have been deferred. Certain officers and Trustees of the Fund are officers of EVM.

4  Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations and including maturities, paydowns, principal repayments on Senior Loans and TBA transactions, for the six months ended April 30, 2021 were as follows:

	Purchases		Sales
Investments (non-U.S. Government)	$	52,166,893	$	60,563,921
U.S. Government and Agency Securities		51,399,159		57,057,503
	$	103,566,052	$	117,621,424

5  Common Shares of Beneficial Interest

The Fund may issue common shares pursuant to its dividend reinvestment plan. There were no common shares issued by the Fund for the six months ended April 30, 2021 and the year ended October 31, 2020.

In November 2013, the Board of Trustees initially approved a share repurchase program for the Fund. Pursuant to the reauthorization of the share repurchase program by the Board of Trustees in March 2019, the Fund is authorized to repurchase up to 10% of its common shares outstanding as of the last day of the prior calendar year at market prices when shares are trading at a discount to net asset value. The repurchase program does not obligate the Fund to purchase a specific amount of shares. There were no repurchases of common shares by the Fund for the six months ended April 30, 2021 and the year ended October 31, 2020.

According to filings made on Schedule 13D and 13G pursuant to Sections 13(d) and 13(g) of the Securities Exchange Act of 1934, as amended, one shareholder owned 39.7% of the Fund’s common shares.

6  Financial Instruments

The Fund may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities. These financial instruments may include forward foreign currency exchange contracts, financial 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 April 30, 2021 is included in the Portfolio of Investments. At April 30, 2021, the Fund had sufficient cash and/or securities to cover commitments under these contracts.

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

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

Foreign Exchange Risk: The Fund holds foreign currency denominated investments. The value of these investments and related receivables and payables may change due to future changes in foreign currency exchange rates. To hedge against this risk, the Fund enters into forward foreign currency exchange contracts.

Interest Rate Risk: The Fund utilizes various interest rate derivatives including futures contracts and interest rate swaps to manage the duration of its portfolio and to hedge against fluctuations in securities prices due to interest rates.

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 April 30, 2021, the fair value of derivatives with credit-related contingent features in a net liability position was $262,706. The aggregate fair value of assets pledged as collateral by the Fund for such liability was $272,000 at April 30, 2021.

April 30, 2021

Notes to Financial Statements (Unaudited) — continued

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 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 carrying amount of the liability for cash collateral due to broker at April 30, 2020 approximated its fair value. If measured at fair value, such liability would have been considered as Level 2 in the fair value hierarchy (see Note 9) at April 30, 2021.

The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure at April 30, 2021 was as follows:

	Fair Value
Statement of Assets and Liabilities Caption	Credit			Foreign Exchange			Interest Rate			Total
Accumulated loss	$	142,533	*	$	10,475	*	$	603,021	*	$	756,029

* For futures contracts and centrally cleared derivatives, amount represents value as shown in the Portfolio of Investments. Only the current day’s variation margin on open futures contracts and centrally cleared derivatives is reported within the Statement of Assets and Liabilities as Receivable or Payable for variation margin on open financial futures contracts and centrally cleared derivatives, as applicable.

* 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.

7  Credit Agreement

The Fund has entered into a Credit Agreement (the Agreement) with a bank to borrow up to a limit of $85 million ($115 million prior to March 16, 2021) pursuant to a 364-day revolving line of credit. Borrowings under the Agreement are secured by the assets of the Fund. Interest is charged at a rate above the London Interbank Offered Rate (LIBOR) and is payable monthly. Under the terms of the Agreement, in effect through March 15, 2022, the Fund pays a commitment fee of 0.15% on the borrowing limit. In connection with the renewal of the Agreement on March 16, 2021, the Fund paid an upfront fee of $42,500, which is being amortized to interest expense through March 15, 2022. The unamortized balance at April 30, 2021 is approximately $37,000 and is included in prepaid upfront fees on notes payable on the Statement of Assets and Liabilities. Also included in interest expense is $21,318 of amortization of previously paid upfront fees related to the period from November 1, 2020 through March 16, 2021 when the Agreement was renewed. The Fund is required to maintain certain net asset levels during the term of the Agreement. At April 30, 2021, the Fund had borrowings outstanding under the Agreement of $26,000,000 at an annual interest rate of 0.97%. Based on the short-term nature of the borrowings under the Agreement and the variable interest rate, the carrying amount of the borrowings at April 30, 2021 approximated its fair value. If measured at fair value, borrowings under the Agreement would have been considered as Level 2 in the fair value hierarchy (see Note 9) at April 30, 2021. For the six months ended April 30, 2021, the average borrowings under the Agreement and the average annual interest rate (excluding fees) were $40,751,381 and 0.96%, respectively.

8  Investments in Affiliated Issuers and Funds

The Fund invested in issuers that may be deemed to be affiliated with Morgan Stanley. At April 30, 2021, the value of the Fund’s investment in affiliated issuers and funds was $23,473,100, which represents 9.5% of the Fund’s net assets.

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 April 30, 2021, 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
Asset-Backed Securities	$	—		$	28,932,883		$	—	$	28,932,883

* None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund.

Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the six months ended April 30, 2021 is not presented.

10  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.

Emerging market securities often involve greater risks than developed market securities. Investment markets within emerging market countries are typically smaller, less liquid, less developed and more volatile than those in more developed markets like the United States, and may be focused in certain economic sectors. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. Governmental actions can have a significant effect on the economic conditions in emerging market countries. It may be more difficult to make a claim or obtain a judgment in the courts of these countries than it is in the United States. The possibility of fraud, negligence, undue influence being exerted by an issuer or refusal to recognize ownership exists in some emerging markets. Disruptions due to work stoppages and trading improprieties in foreign securities markets have caused such markets to close. Emerging market securities are also subject to speculative trading, which contributes to their volatility.

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.

LIBOR Transition Risk

Certain instruments held by the Fund may pay an interest rate based on the London Interbank Offered Rate (“LIBOR”), which is the average offered rate for various maturities of short-term loans between certain major international banks. LIBOR is used throughout global banking and financial industries to determine interest rates for a variety of financial instruments (such as debt instruments and derivatives) and borrowing arrangements. The ICE Benchmark Administration Limited, the administrator of LIBOR, is expected to cease publishing certain LIBOR settings on December 31, 2021, and the remaining LIBOR settings on June 30, 2023. Although the transition process away from LIBOR is expected to be defined in advance of the anticipated discontinuation, there remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate or rates. The phase-out of LIBOR may result in, among other things, increased volatility or illiquidity in markets for instruments based on LIBOR and changes in the value of such instruments.

Pandemic Risk

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

11  Subsequent Event

At a special meeting of shareholders held on May 7, 2021, Fund shareholders approved the New Agreement with EVM, having substantially the same terms and conditions as the investment advisory agreement in effect prior to March 1, 2021. As announced on March 9, 2021, conditioned on shareholder approval of the New Agreement, the Fund’s Board of Trustees authorized 1) a conditional cash tender offer by the Fund for up to 25% of its outstanding common shares at a price per share equal to 99% of the Fund’s net asset value (“NAV”) per share as of the close of regular trading on the New York Stock Exchange on the date the tender offer expires and 2) a conditional increase in the Fund’s regular monthly distribution on common shares to an annual rate of 10% of the Fund’s then-current NAV. As of May 7, 2021, the condition was met. As of the date these financial statements were issued, the Fund had not commenced the tender offer. The Fund increased its regular monthly distribution on common shares beginning in June 2021.

Abstentions and broker non-votes had the effect of a negative vote on Proposal 1. Broker non-votes were not expected with respect to Proposal 1 because brokers are required to receive instructions from the beneficial owners or persons entitled to vote in order to submit proxies.

Following the March 9, 2021 announcement of a cash tender offer and distribution rate increase, each conditioned on shareholder approval of a new investment advisory agreement with EVM, the Fund held a Special Meeting of Shareholders on May 7, 2021 for the following purpose: approval of a new investment advisory agreement with EVM (“Proposal 1”).

Board of Trustees’ Contract Approval

Overview of the Contract Review Process

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

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

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

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

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

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

• Information about the advantages of the Transaction as they relate to the Funds and their shareholders;

• A commitment that Morgan Stanley would use its reasonable best efforts to ensure that it did not impose any “unfair burden” (as that term is used in section 15(f)(1)(B) of the 1940 Act) on the Funds as a result of the Transaction;

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

Nature, Extent and Quality of Services

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

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

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

Board of Trustees’ Contract Approval — continued

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

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

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

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

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

Management Fees and Expenses

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

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

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

Board of Trustees’ Contract Approval — continued

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

Profitability and “Fall-Out” Benefits

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

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

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

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

Economies of Scale

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

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

Conclusion

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

IMPORTANT NOTICES

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

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

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

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

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

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