1  Significant Accounting Policies

International Income Portfolio (the Portfolio) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, open-end management investment company. The Portfolio’s investment objective is total return. The Declaration of Trust permits the Trustees to issue interests in the Portfolio. At April 30, 2015, Eaton Vance Diversified Currency Income Fund, Eaton Vance International (Cayman Islands) Short Duration Strategic Income Fund and Eaton Vance Short Duration Strategic Income Fund held an interest of 97.6%, less than 0.5% and less than 0.5%, respectively, in the Portfolio.

Prior to April 2, 2015, the Portfolio sought to gain exposure to the commodity markets, in whole or in part, through investments in Eaton Vance IIP Commodity Subsidiary, Ltd. (the Subsidiary), a wholly-owned subsidiary of the Portfolio organized under the laws of the Cayman Islands with the same objective and investment policies and restrictions as the Portfolio. As of the close of business on April 1, 2015, the Portfolio fully redeemed its investment in the Subsidiary. Net assets of the Subsidiary at such date, consisting primarily of cash and investments, were transferred to the Portfolio with no gain or loss for financial reporting purposes. The Portfolio is in the process of dissolving the Subsidiary with the Cayman Islands authorities and it is scheduled to dissolve on or about October 31, 2015. The accompanying consolidated financial statements include the accounts of the Subsidiary through April 1, 2015. Intercompany balances and transactions have been eliminated in consolidation.

The following is a summary of significant accounting policies of the Portfolio. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Portfolio 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 (including short-term obligations with a remaining maturity of more than sixty days) 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 asked 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 obligations purchased with a remaining maturity of sixty days or less (excluding those that are non-U.S. dollar denominated, which typically are valued by a pricing service or dealer quotes) are generally valued at amortized cost, which approximates market value.

Commodities. Precious metals are valued at the New York composite mean quotation reported by Bloomberg at the valuation time.

Derivatives. Financial and commodities 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 asked 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 Portfolio’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. In the case of total return swaps, the pricing service valuations are based on the value of the underlying index or instrument and reference interest rate. 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. When valuing foreign equity securities that meet certain criteria, the Portfolio’s Trustees have approved the use of a fair value service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that have a strong correlation to the fair-valued securities.

Affiliated Fund. The Portfolio may invest in Eaton Vance Cash Reserves Fund, LLC (Cash Reserves Fund), an affiliated investment company managed by Eaton Vance Management (EVM). The value of the Portfolio’s investment in Cash Reserves Fund reflects the Portfolio’s proportionate interest in its net assets. Cash Reserves Fund generally values its investment securities utilizing the amortized cost valuation technique in accordance with Rule 2a-7 under the 1940 Act. This technique involves initially valuing a portfolio security at its cost and thereafter assuming a constant amortization to maturity of any discount or premium. If amortized cost is determined not to approximate fair value, Cash Reserves Fund may value its investment securities in the same manner as debt obligations described above.

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 Portfolio in a manner that fairly reflects the security’s value, or the amount that the Portfolio might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of

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

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

C  Income — Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount. Inflation adjustments to the principal amount of inflation-adjusted bonds and notes are reflected as interest income. Withholding taxes on foreign interest have been provided for in accordance with the Portfolio’s understanding of the applicable countries’ tax rules and rates.

D  Federal and Other Taxes — The Portfolio has elected to be treated as a partnership for federal tax purposes. No provision is made by the Portfolio for federal or state taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes on its share of taxable income. Since at least one of the Portfolio’s investors is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the applicable source of income and diversification requirements (under the Internal Revenue Code) in order for its investors to satisfy them. The Portfolio will allocate, at least annually among its investors, each investor’s distributive share of the Portfolio’s net investment income, net realized capital gains and any other items of income, gain, loss, deduction or credit.

The Subsidiary is treated as a controlled foreign corporation under the Internal Revenue Code and is not expected to be subject to U.S. federal income tax. The Portfolio is treated as a U.S. shareholder of the Subsidiary. As a result, the Portfolio is required to include in gross income for U.S. federal tax purposes all of the Subsidiary’s income, whether or not such income is distributed by the Subsidiary. If a net loss is realized by the Subsidiary, such loss is not generally available to offset the income earned by the Portfolio.

As of April 30, 2015, the Portfolio had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Portfolio 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  Expense Reduction — State Street Bank and Trust Company (SSBT) serves as custodian of the Portfolio. Pursuant to the custodian agreement, SSBT receives a fee reduced by credits, which are determined based on the average daily cash balance the Portfolio maintains with SSBT. All credit balances, if any, used to reduce the Portfolio’s custodian fees are reported as a reduction of expenses in the Consolidated Statement of Operations.

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

I  Financial and Commodities Futures Contracts — Upon entering into a financial or commodities futures contract, the Portfolio 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 Portfolio each business day, depending on the daily fluctuations in the value of the underlying security or commodity, and are recorded as unrealized gains or losses by the Portfolio. Gains (losses) are realized upon the expiration or closing of the financial or commodities futures contracts. Should market conditions change unexpectedly, the Portfolio may not achieve the anticipated benefits of the financial or commodities 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.

23

International Income Portfolio

April 30, 2015

Notes to Consolidated Financial Statements (Unaudited) — continued

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

K  Interest Rate Swaps — Pursuant to interest rate swap agreements, the Portfolio either makes floating-rate payments to the counterparty based on a benchmark interest rate in exchange for fixed-rate payments or the Portfolio makes fixed-rate payments to the counterparty in exchange for payments on a floating benchmark interest rate. Payments received or made 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. The value of the swap is determined by changes in the relationship between two rates of interest. The Portfolio is exposed to credit loss in the event of non-performance by the swap counterparty. Risk may also arise from movements in interest rates.

L  Total Return Swaps — In a total return swap, the buyer receives a periodic return equal to the total return of a specified security, securities or index for a specified period of time. In return, the buyer pays the counterparty a variable stream of payments, typically based upon short-term interest rates, possibly plus or minus an agreed upon spread. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains and losses. Periodic payments received or made are recorded as realized gains or losses. The Portfolio is exposed to credit loss in the event of nonperformance by the swap counterparty. Risk may also arise from the unanticipated movements in value of exchange rates, interest rates, securities, or the index.

M  Interim Consolidated Financial Statements — The interim consolidated financial statements relating to April 30, 2015 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Portfolio’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the consolidated financial statements.

2  Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Boston Management and Research (BMR), a subsidiary of EVM, as compensation for investment advisory services rendered to the Portfolio and the Subsidiary. Pursuant to the investment advisory agreement between the Portfolio and BMR and the investment advisory agreement between the Subsidiary and BMR, the Portfolio and Subsidiary each pay BMR a fee at an annual rate of 0.625% of its respective average daily net assets up to $1 billion, 0.600% from $1 billion but less than $2 billion, and at reduced rates on daily net assets of $2 billion or more, and is payable monthly. In determining the investment adviser fee for the Portfolio and Subsidiary, the applicable advisory fee rate is based on the average daily net assets of the Portfolio (inclusive of its interest in the Subsidiary). Such fee rate is then assessed separately on the Portfolio’s average daily net assets (exclusive of its interest in the Subsidiary) and the Subsidiary’s average daily net assets to determine the amount of the investment adviser fee. For the six months ended April 30, 2015, the Portfolio’s investment adviser fee amounted to $1,324,221 or 0.625% (annualized) of the Portfolio’s consolidated average daily net assets. The Portfolio invests its cash in Cash Reserves Fund. EVM does not currently receive a fee for advisory services provided to Cash Reserves Fund.

Trustees and officers of the Portfolio who are members of EVM’s or BMR’s organizations receive remuneration for their services to the Portfolio out of the investment adviser fee. Trustees of the Portfolio who are not affiliated with the investment adviser may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended April 30, 2015, no significant amounts have been deferred. Certain officers and Trustees of the Portfolio are officers of the above organizations.

3  Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations and including maturities and paydowns, for the six months ended April 30, 2015 were as follows:

	Purchases		Sales
Investments (non-U.S. Government)	$	19,312,754	$	96,837,222
U.S. Government and Agency Securities		—		619,619

4  Federal Income Tax Basis of Investments

The cost and unrealized appreciation (depreciation) of investments of the Portfolio at April 30, 2015, as determined on a federal income tax basis, were as follows:

Aggregate cost	$	359,958,570
Gross unrealized appreciation	$	2,444,738
Gross unrealized depreciation		(24,532,269	)
Net unrealized depreciation	$	(22,087,531	)

5  Financial Instruments

The Portfolio 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 Portfolio 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, 2015 is as follows:

At April 30, 2015, the Portfolio had sufficient cash and/or securities to cover commitments under these contracts.

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

Foreign Exchange Risk:  The Portfolio engages in forward foreign currency exchange contracts and total return swaps 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.

Interest Rate Risk:  The Portfolio utilizes futures contracts to enhance total return, to seek to hedge against fluctuations in interest rates, and/or to change the effective duration of its portfolio.

The Portfolio enters into swap contracts and forward foreign currency exchange contracts that may contain provisions whereby the counterparty may terminate the contract under certain conditions, including but not limited to a decline in the Portfolio’s net assets below a certain level over a certain period of time, which would trigger a payment by the Portfolio for those derivatives in a liability position. At April 30, 2015, the fair value of derivatives with credit-related contingent features in a net liability position was $7,594,642. The aggregate fair value of assets pledged as collateral by the Portfolio for such liability was $4,595,420 at April 30, 2015.

The over-the-counter (OTC) derivatives in which the Portfolio 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 Portfolio 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 Portfolio 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 Portfolio 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 Portfolio’s net assets decline by a stated percentage or the Portfolio fails to meet the terms of its ISDA Master Agreements, which would cause the counterparty to accelerate payment by the Portfolio 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 Portfolio and/or counterparty is held in segregated accounts by the Portfolio’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 restricted cash and, in the case of cash pledged by a counterparty for the benefit of the Portfolio, a corresponding liability on the Consolidated Statement of Assets and Liabilities. Securities pledged by the Portfolio as collateral, if any, are identified as such in the Consolidated Portfolio of Investments. The carrying amount of the liability for cash collateral due to brokers at April 30, 2015 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 8) at April 30, 2015.

Foreign Exchange	Forward foreign currency exchange contracts	$	9,771,854		$	(8,009,436	)
Interest Rate	Financial futures contracts		(165,022	)		9,556
Total		$	9,606,832		$	(7,999,880	)

⁽¹⁾  Consolidated Statement of Operations location: Net realized gain (loss) – Foreign currency and forward foreign currency exchange contract transactions and Financial futures contracts, respectively.

⁽²⁾  Consolidated Statement of Operations location: Change in unrealized appreciation (depreciation) – Foreign currency and forward foreign currency exchange contracts and Financial futures contracts, respectively.

The average notional amounts of futures contracts and forward foreign currency exchange contracts outstanding during the six months ended April 30, 2015, which are indicative of the volume of these derivative types, were approximately $6,848,000 and $435,119,000, respectively.

6  Line of Credit

The Portfolio participates with other portfolios and funds managed by EVM and its affiliates in a $750 million unsecured line of credit agreement with a group of banks, which is in effect through September 7, 2015. Borrowings are made by the Portfolio solely to facilitate the handling of unusual and/or unanticipated short-term cash requirements. Interest is charged to the Portfolio based on its borrowings at an amount above either the Eurodollar rate or Federal Funds rate. In addition, a fee computed at an annual rate of 0.08% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. Because the line of credit is not available exclusively to the Portfolio, it may be unable to borrow some or all of its requested amounts at any particular time. The Portfolio did not have any significant borrowings or allocated fees during the six months ended April 30, 2015.

7  Risks Associated with Foreign Investments

The Portfolio’s investments in foreign instruments can be adversely affected by changes in currency exchange rates and political, economic and market developments abroad. In emerging or less developed countries, these risks can be more significant. Investment markets in emerging market countries are typically substantially smaller, less liquid and more volatile than the major markets in developed countries. Emerging market countries may have relatively unstable governments and economies. Emerging market investments often are subject to speculative trading, which typically contributes to volatility.

The Portfolio may have difficulties enforcing its legal or contractual rights in a foreign country. Economic data as reported by foreign governments and other issuers 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 foreign government to renegotiate defaulted debt may be limited.

8  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.

Ÿ Level 1 – quoted prices in active markets for identical investments

Ÿ Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

Ÿ 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, 2015, the hierarchy of inputs used in valuing the Portfolio’s investments and open derivative instruments, which are carried at value, were as follows:

Asset Description	Level 1			Level 2			Level 3		Total
Foreign Government Bonds	$	—		$	130,112,868		$	—	$	130,112,868
Foreign Corporate Bonds		—			1,530,041			—		1,530,041

Total	$	(55,838	)	$	(7,594,642	)	$	—	$	(7,650,480	)

The Portfolio held no investments or other financial instruments as of October 31, 2014 whose fair value was determined using Level 3 inputs. At April 30, 2015, there were no investments transferred between Level 1 and Level 2 during the six months then ended.

Board of Trustees’ Contract Approval

Overview of the Contract Review Process

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

At a meeting of the Boards of Trustees (each a “Board”) of the registered investment companies advised, administered and/or distributed by Eaton Vance Management or its affiliates (the “Eaton Vance Funds”) held on April 27, 2015, the Board, including a majority of the Independent Trustees, voted to approve continuation of existing investment advisory and sub-advisory agreements for the Eaton Vance Funds for an additional one-year period. In voting its approval, the Board relied upon the affirmative recommendation of its Contract Review Committee, which is a committee comprised exclusively of Independent Trustees. Prior to making its recommendation, the Contract Review Committee reviewed information furnished by each adviser to the Eaton Vance Funds (including information specifically requested by the Board) for a series of meetings of the Contract Review Committee held between February and April 2015. The Contract Review Committee also considered information received at prior meetings of the Board and its committees, as relevant to its annual evaluation of the investment advisory and sub-advisory agreements.

The information that the Board considered included, among other things, the following:

Information about Fees, Performance and Expenses

Ÿ A report from an independent data provider comparing the advisory and related fees paid by each fund with fees paid by comparable funds as identified by the data provider (“comparable funds”);

Ÿ A report from an independent data provider comparing each fund’s total expense ratio and its components to comparable funds;

Ÿ A report from an independent data provider comparing the investment performance of each fund (including, where relevant, yield data, Sharpe ratios and information ratios) to the investment performance of comparable funds over various time periods;

Ÿ Data regarding investment performance in comparison to benchmark indices and customized peer groups identified by the adviser in consultation with the Board;

Ÿ For each fund, comparative information concerning the fees charged and the services provided by each adviser in managing other accounts (including mutual funds, other collective investment funds and institutional accounts) using investment strategies and techniques similar to those used in managing such fund;

Ÿ Profitability analyses for each adviser with respect to each fund;

Information about Portfolio Management and Trading

Ÿ Descriptions of the investment management services provided to each fund, including the investment strategies and processes it employs;

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

Ÿ Information about each adviser’s policies and practices with respect to trading, including each adviser’s processes for monitoring best execution of portfolio transactions;

Ÿ Information about the allocation of brokerage transactions and the benefits received by each adviser as a result of brokerage allocation, including information concerning the acquisition of research through client commission arrangements and policies with respect to “soft dollars”;

Ÿ Data relating to portfolio turnover rates of each fund;

Information about each Adviser

Ÿ Reports detailing the financial results and condition of each adviser;

Ÿ Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;

Ÿ The Code of Ethics of each adviser and its affiliates, together with information relating to compliance with and the administration of such codes;

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

Ÿ Information concerning the resources devoted to compliance efforts undertaken by each adviser and its affiliates (including descriptions of various compliance programs) and their record of compliance;

Ÿ Descriptions of the business continuity and disaster recovery plans of each adviser and its affiliates;

Ÿ A description of Eaton Vance Management’s procedures for overseeing third party advisers and sub-advisers, including with respect to regulatory and compliance issues, investment management and other matters;

Ÿ Information concerning management of the relationship with the custodian, subcustodians and fund accountants by each adviser or the funds’ administrator; and

Ÿ The terms of each investment advisory agreement.

Over the course of the twelve-month period ended April 30, 2015, with respect to one or more funds, the Board met nine times and the Contract Review Committee, the Audit Committee, the Governance Committee, the Portfolio Management Committee and the Compliance Reports and Regulatory Matters Committee, each of which is a Committee comprised solely of Independent Trustees, met eight, seventeen, seven, eleven and thirteen times, respectively. At such meetings, the Trustees participated in investment and performance reviews with the portfolio managers and other investment professionals of each adviser relating to each fund, and considered the investment and trading strategies used in pursuing each fund’s investment objective, including, where relevant, the use of derivative instruments, as well as processes for monitoring best execution of portfolio transactions and risk management techniques. The Board and its Committees also evaluated issues pertaining to industry and regulatory developments, compliance procedures, fund governance and other issues with respect to the funds, and received and participated in reports and presentations provided by Eaton Vance Management and other fund advisers with respect to such matters. In addition to the formal meetings of the Board and its Committees, the Independent Trustees hold regular teleconferences in between meetings to discuss, among other topics, matters relating to the continuation of investment advisory and sub-advisory agreements.

For funds that invest through one or more underlying portfolios, the Board considered similar information about the portfolio(s) when considering the approval of investment advisory agreements. In addition, in cases where the fund’s investment adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any sub-advisory agreement.

The Contract Review Committee was assisted throughout the contract review process by Goodwin Procter LLP, legal counsel for the Independent Trustees. The members of the Contract Review Committee relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each investment advisory and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each investment advisory and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Contract Review Committee may have placed varying emphasis on particular factors in reaching conclusions with respect to each investment advisory and sub-advisory agreement. In evaluating each investment advisory and sub-advisory agreement, including the specific fee structures and other terms of the agreements, the Contract Review Committee was informed by multiple years of analysis and discussion among the Independent Trustees and the Eaton Vance Funds’ advisers and sub-advisers.

Results of the Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Contract Review Committee concluded that the continuation of the investment advisory agreement of Eaton Vance Diversified Currency Income Fund (the “Fund”) with Eaton Vance Management (“EVM”), as well as the investment advisory agreement of International Income Portfolio (the “Portfolio”), the portfolio in which the Fund invests, with Boston Management and Research (“BMR”), an affiliate of EVM (EVM, with respect to the Fund, and BMR, with respect to the Portfolio, are each referred to herein as the “Adviser”), including their fee structures, is in the interests of shareholders and, therefore, the Contract Review Committee recommended to the Board approval of each agreement. The Board accepted the recommendation of the Contract Review Committee as well as the factors considered and conclusions reached by the Contract Review Committee with respect to the agreements. Accordingly, the Board, including a majority of the Independent Trustees, voted to approve continuation of the investment advisory agreements for the Fund and the Portfolio.

Nature, Extent and Quality of Services

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

The Board considered each Adviser’s management capabilities and investment process with respect to the types of investments held by the Fund and the Portfolio, including the education, experience and number of its investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Fund and the Portfolio. The Board considered the Adviser’s expertise with respect to global markets and in-house research capabilities. The Board also took into account the resources dedicated to portfolio management and other services, as well as the compensation methods of each Adviser and other factors, such as the reputation and resources of the Adviser to recruit and retain investment personnel. In addition, the Board considered the time and attention devoted to the Fund and the Portfolio by senior management, as well as the infrastructure, operational capabilities and support staff in place to assist in the management of the Fund and the Portfolio, including the provision of administrative services.

The Board noted that under the terms of the investment advisory agreement of the Fund, EVM may invest assets of the Fund directly in securities, for which it may receive a fee, or in the Portfolio, for which it receives no separate fee but for which BMR receives an advisory fee from the Portfolio.

Board of Trustees’ Contract Approval — continued

The Board considered the compliance programs of each Adviser and relevant affiliates thereof. Among other matters, the Board considered compliance and reporting matters relating to personal trading by investment personnel, selective disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also considered the responses of each Adviser and its affiliates to requests in recent years from regulatory authorities such as the Securities and Exchange Commission and the Financial Industry Regulatory Authority.

The Board considered shareholder and other administrative services provided or managed by Eaton Vance Management and its affiliates, including transfer agency and accounting services. The Board evaluated the benefits to shareholders of investing in a fund that is a part of a large family of funds, including the ability, in many cases, to exchange an investment among different funds without incurring additional sales charges.

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

Fund Performance

The Board compared the Fund’s investment performance to that of comparable funds and appropriate benchmark indices, as well as a customized peer group of similarly managed funds. The Board’s review included comparative performance data for the one-, three- and five-year periods ended September 30, 2014 for the Fund. The Board concluded that the performance of the Fund was satisfactory.

Management Fees and Expenses

The Board considered contractual fee rates payable by the Portfolio and by the Fund for advisory and administrative services (referred to collectively as “management fees”). As part of its review, the Board considered the Fund’s management fees and total expense ratio for the year ended September 30, 2014, as compared to those of comparable funds, before and after giving effect to any undertaking to waive fees or reimburse expenses. The Board noted that the Portfolio has established a wholly-owned subsidiary to accommodate the Portfolio’s commodity-related investments. The subsidiary is managed pursuant to a separate investment advisory agreement that is subject to annual approval by the Board. The subsidiary’s fee rates are the same as those charged to the Portfolio, and the Portfolio will not pay any additional management fees with respect to its assets invested in the subsidiary. The Board considered certain Fund specific factors that had an impact on Fund expense ratios relative to comparable funds, as identified by management in response to inquiries from the Contract Review Committee. The Board also considered actions taken by management in recent years to reduce expenses at the fund complex level.

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

Profitability

The Board considered the level of profits realized by each Adviser and relevant affiliates thereof in providing investment advisory and administrative services to the Fund, to the Portfolio and to all Eaton Vance Funds as a group. The Board considered the level of profits realized without regard to revenue sharing or other payments by each Adviser and its affiliates to third parties in respect of distribution services. The Board also considered other direct or indirect benefits received by each Adviser and its affiliates in connection with their relationships with the Fund and the Portfolio, including the benefits of research services that may be available to each Adviser as a result of securities transactions effected for the Fund and the Portfolio and other investment advisory clients.

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by each Adviser and its affiliates are reasonable.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the applicable Adviser and its affiliates, on the one hand, and the Fund and the Portfolio, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund and the Portfolio increase. The Board acknowledged the difficulty in accurately measuring the benefits resulting from the economies of scale with respect to the management of any specific fund or group of funds. The Board reviewed data summarizing the increases and decreases in the assets of the Fund and of all Eaton Vance Funds as a group over various time periods, and evaluated the extent to which the total expense ratio of the Fund and the profitability of each Adviser and its affiliates may have been affected by such increases or decreases. Based upon the foregoing, the Board concluded that the Fund currently shares in the benefits from economies of scale. The Board also concluded that, assuming reasonably foreseeable increases in the assets of the Fund and the Portfolio, the structure of the advisory fees, which include breakpoints at several asset levels, will allow the Fund and the Portfolio to continue to benefit from economies of scale in the future.

Ÿ We reserve the right to change our Privacy Policy at any time upon proper notification to you. Customers may want to review our Privacy Policy periodically for changes by accessing the link on our homepage: www.eatonvance.com.

Our pledge of privacy applies to the following entities within the Eaton Vance organization: the Eaton Vance Family of Funds, Eaton Vance Management, Eaton Vance Investment Counsel, Eaton Vance Distributors, Inc., Eaton Vance Trust Company, Eaton Vance Management’s Real Estate Investment Group and Boston Management and Research. In addition, our Privacy Policy applies only to those Eaton Vance customers who are individuals and who have a direct relationship with us.

This notice supersedes all previously issued privacy disclosures. For more information about Eaton Vance’s Privacy Policy, please call 1-800-262-1122.

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 advisor, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial advisor, 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 advisor. Your instructions that householding not apply to delivery of your Eaton Vance documents will be effective within 30 days of receipt by Eaton Vance or your financial advisor.

Portfolio Holdings.  Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) will file a schedule of portfolio holdings on Form N-Q with the SEC for the first and third quarters of each fiscal year. The Form N-Q will be available on the Eaton Vance website at www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC’s website at www.sec.gov. Form N-Q may also be reviewed and copied at the SEC’s public reference room in Washington, D.C. (call 1-800-732-0330 for information on the operation of the public reference room).

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