Valuing Shares

Each Fund values its shares once each day only when the New York Stock Exchange is open for trading (typically Monday through Friday), as of the close of regular trading on the Exchange (normally 4:00 p.m. eastern time). The purchase price of Fund shares is their net asset value (plus a sales charge for Class A shares), which is derived from Fund or Portfolio holdings. When purchasing or redeeming Fund shares, your investment dealer must communicate your order to the principal underwriter by a specific time each day in order for the purchase price or the redemption price to be based on that day’s net asset value per share. It is the investment dealer’s responsibility to transmit orders promptly. Each Fund may accept purchase and redemption orders as of the time of their receipt by certain investment dealers (or their designated intermediaries).

The Trustees have adopted procedures for valuing investments and have delegated to the investment adviser the daily valuation of such investments. For International Equity Portfolio and Structured Emerging Markets Fund, the investment adviser has delegated daily valuation of the Portfolio and Fund, respectively, to a sub-adviser. Pursuant to the procedures, exchange-listed securities normally are valued at closing sale prices. In certain situations, the investment adviser may use the fair value of a security if prices are unavailable or are deemed unreliable, or if events occur after the close of a securities market (usually a foreign market) and before a Fund or Portfolio values its assets that would materially affect net asset value. In addition, for foreign equity securities that meet certain criteria, the 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. A security that is fair valued may be valued at a price higher or lower than actual market quotations or the value determined by other funds using their own fair valuation procedures. Because foreign securities trade on days when Fund shares are not priced, the value of securities held by a Fund or Portfolio can change on days when Fund shares cannot be redeemed. The investment adviser expects to fair value domestic securities in limited circumstances, such as when the securities are subject to restrictions on resale. Eaton Vance has established a Valuation Committee that oversees the valuation of investments.

Purchasing Shares Class A, Class C and Class R

You may purchase shares through your investment dealer or by mailing an account application form to the transfer agent (see back cover for address). You may request an account application by calling 1-800-262-1122. Your initial investment must be at least $1,000.

After your initial investment, additional investments may be made at any time by sending a check payable to the order of the Fund or the transfer agent directly to the transfer agent (see back cover for address). Please include your name and account number and the name of the Fund and Class of shares with each investment.

You may make automatic investments of $50 or more each month or each quarter from your bank account. You can establish bank automated investing on the account application or by calling 1-800-262-1122. The minimum initial investment amount and Fund policy of redeeming accounts with low account balances are waived for bank automated investing accounts, certain group purchase plans (including tax-deferred retirement, other pension plans and proprietary fee-based programs sponsored by broker-dealers), the ReFlow liquidity program and for persons affiliated with Eaton Vance and certain Fund service providers (as described in the Statement of Additional Information).

Purchase orders will be executed at the net asset value next determined after their receipt by a Fund. A Fund or your investment dealer must receive your purchase order no later than the close of regular trading on the New York Stock Exchange (normally 4:00 p.m. eastern time) in order for your purchase to be effected at that day’s net asset value. If you purchase shares through an investment dealer (which includes brokers, dealers and other financial institutions), that dealer may charge you a fee for executing the purchase for you. Each Fund may suspend the sale of its shares at any time and any purchase order may be refused.

Class I Shares

Class I shares are offered to clients of financial intermediaries who charge such clients an ongoing fee for advisory, investment, consulting or similar services. Such clients may include individuals, corporations, endowments, foundations and qualified plans (including tax-deferred retirement plans and profit sharing plans). Class I shares are also offered to investment and institutional clients of Eaton Vance and its affiliates and certain persons affiliated with Eaton Vance and certain fund service providers. Your initial investment must be at least $250,000. Subsequent investments of any amount may be made at any time. The minimum initial investment is waived for persons affiliated with Eaton Vance, its affiliates and certain Fund service providers (as described in the Statement of Additional Information), and the ReFlow liquidity program. The initial minimum investment also is waived for individual accounts of a financial intermediary that charges an ongoing fee for its services (as described below), provided the aggregate value of such accounts invested in Class I shares of the Fund is at least $250,000 (or is anticipated by the principal underwriter to reach $250,000) and for corporations, endowments, foundations and qualified plans with assets of at least $100 million.

Class I shares may be purchased through an investment dealer or by requesting your bank to transmit immediately available funds (Federal Funds) by wire to the address set forth below. To make an initial investment by wire, you must first telephone the Fund Order Department at 1-800-225-6265 (extension 7604) to advise of your action and to be assigned an account number. Failure to call will delay the order. An account application form must be promptly forwarded to the transfer agent (see back cover for address). You may request a current account application by calling 1-800-262-1122. Additional investments may be made at any time through the same wire procedure. The Fund Order Department must be advised by telephone of each transmission. Wire funds to:

ABA #011001234 Account #080411 Further Credit: Eaton Vance Dividend Income Fund - Class I Shares - Fund #397 OR                        Eaton Vance International Equity Fund - Class I Shares - Fund #86 OR                        Eaton Vance Structured Emerging Markets Fund - Class I Shares - Fund #83                       A/C # [Insert your account number]

Purchase orders will be executed at the net asset value next determined after their receipt by each Fund. A Fund or your investment dealer must receive your purchase order no later than the close of regular trading on the New York Stock Exchange (normally 4:00 p.m. eastern time) in order for your purchase to be effected at that day’s net asset value. If you purchase shares through an investment dealer, that dealer may charge you a fee for executing the purchase for you. Each Fund may suspend the sale of its shares at any time and any purchase order may be refused.

Restrictions on Excessive Trading and Market Timing. The Funds are not intended for excessive trading or market timing. Market timers seek to profit by rapidly switching money into a fund when they expect the share price of the fund to rise and taking money out of the fund when they expect those prices to fall. By realizing profits through short-term trading, shareholders that engage in rapid purchases and sales or exchanges of a fund’s shares may dilute the value of shares held by long-term shareholders. Volatility resulting from excessive purchases and sales or exchanges of fund shares, especially involving large dollar amounts, may disrupt efficient portfolio management. In particular, excessive purchases and sales or exchanges of a fund’s shares may cause a fund to have difficulty implementing its investment strategies, may force the fund to sell portfolio securities at inopportune times to raise cash or may cause increased expenses (such as increased brokerage costs, realization of taxable capital gains without attaining any investment advantage or increased administrative costs).

A fund that invests in securities that are, among other things, thinly traded, traded infrequently or relatively illiquid (including restricted securities and emerging market securities and certain small-cap companies for Structured Emerging Markets Fund) is susceptible to the risk that the current market price for such securities may not accurately reflect current market values. A shareholder may seek to engage in short-term trading to take advantage of these pricing differences (commonly referred to as “price arbitrage”). In addition, because each Fund and Portfolio invests in foreign securities, it may be susceptible to a time zone arbitrage strategy in which shareholders attempt to take advantage of Fund share prices that may not reflect developments in a foreign securities market that occur after the close of such market but prior to the pricing of Fund shares. The investment adviser or the sub-adviser is authorized to use the fair value of a security if prices are unavailable or are deemed unreliable (see “Valuing Shares”). The use of fair value pricing, the redemption fee applicable to Class A and Class I shares of International Equity Fund and Structured Emerging Markets Fund, and the

17

restrictions on excessive trading and market timing described below are intended to reduce a shareholder’s ability to engage in price or time zone arbitrage to the detriment of the Funds.

The Boards of Trustees of the Eaton Vance funds have adopted policies to discourage short-term trading and market timing and to seek to minimize their potentially detrimental effects. Pursuant to these policies, if an investor (through one or more accounts) makes more than two round-trip exchanges (exchanging from one fund to another fund and back again) within 12 months, it will be deemed to constitute market timing or excessive trading. Under the policies, each Fund or its principal underwriter will reject or cancel a purchase order, suspend or terminate the exchange privilege or terminate the ability of an investor to invest in the Eaton Vance funds if the Fund or the principal underwriter determines that a proposed transaction involves market timing or excessive trading that it believes is likely to be detrimental to the Fund. Each Fund and its principal underwriter cannot ensure that they will be able to identify all cases of market timing and excessive trading, although they believe they have adequate procedures in place to attempt to do so. Each Fund or its principal underwriter may also reject or cancel any purchase order (including an exchange) from an investor or group of investors for any other reason. Decisions to reject or cancel purchase orders (including exchanges) in each Fund are inherently subjective and will be made in a manner believed to be in the best interest of a Fund’s shareholders. No Eaton Vance fund has any arrangement to permit market timing. Investments in each Fund by ReFlow in connection with the ReFlow liquidity program (which is described under "Investment Objectives & Principal Policies and Risks" above) are not subject to the two round trip limitation.

The Funds and the principal underwriter have provided guidance to financial intermediaries (such as banks, broker-dealers, insurance companies and retirement administrators) concerning the application of the Eaton Vance funds’ market timing and excessive trading policies to Fund shares held in omnibus accounts maintained and administered by such intermediaries, including guidance concerning situations where market timing or excessive trading is considered to be detrimental to a Fund. Each Fund or its principal underwriter may rely on a financial intermediary’s policy to restrict market timing and excessive trading if it believes that policy is likely to prevent market timing that is likely to be detrimental to each Fund. Such policy may be more or less restrictive than a Fund’s policy. Each Fund and the principal underwriter cannot ensure that these financial intermediaries will in all cases apply the policies of the Funds or their own policies, as the case may be, to accounts under their control.

Choosing a Share Class. Each Fund offers different classes of shares. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different sales charges and expenses and will likely have different share prices due to differences in class expenses. In choosing the class of shares that suits your investment needs, you should consider:

• how long you expect to own your shares;
• how much you intend to invest;
• the sales charge and total operating expenses associated with owning each class; and
• whether you qualify for a reduction or waiver of any applicable sales charges (see “Reducing or Eliminating Class A Sales Charges” under “Sales Charges” below).

Each investor’s considerations are different. You should speak with your investment dealer to help you decide which class of shares is best for you. Set forth below is a brief description of each class of shares offered by the Funds.

Class A shares are offered at net asset value plus a front-end sales charge of up to 5.75% . This charge is deducted from the amount you invest. The Class A sales charge is reduced for purchases of $50,000 or more. The sales charge applicable to your purchase may be reduced under the right of accumulation or a statement of intention, which are described in “Reducing or Eliminating Class A Sales Charges” under “Sales Charges” below. Some investors may be eligible to purchase Class A shares at net asset value under certain circumstances, which are also described below. Purchases of Class A shares of International Equity Fund and Structured Emerging Markets Fund are subject to a 1% redemption fee if redeemed within 90 days of settlement of purchase. Class A shares pay distribution and service fees equal to 0.25% annually of average daily net assets. Returns on Class A shares are generally higher than returns on Class C and Class R shares because Class A has lower annual expenses than those classes.

18

Class C shares are offered at net asset value with no front-end sales charge. If you sell your Class C shares within 12 months of purchase, you generally will be subject to a CDSC. The CDSC is deducted from your redemption proceeds. Under certain circumstances, the Class C CDSC may be waived (such as certain redemptions from tax-deferred retirement plan accounts). See “CDSC Waivers” under “Sales Charges” below. Class C shares pay distribution fees and service fees equal to 1.00% annually of average daily net assets. Returns on Class C shares are generally lower than returns on Class A shares because Class C has higher annual expenses than Class A.

Orders for Class C shares of one or more Eaton Vance funds will be refused when the total value of the purchase (including the aggregate value of all Eaton Vance fund shares held within the purchasing shareholder’s account) is $1,000,000 or more. Investors considering cumulative purchases of $1,000,000 or more, or who, after a purchase of shares, would own shares of Eaton Vance funds with a current market value of $1,000,000 or more, should consider whether Class A shares would be more advantageous and consult their investment dealer.

Class I shares are offered to clients of financial intermediaries who charge such clients an ongoing fee for advisory, investment, consulting or similar services. Such clients may include individuals, corporations, endowments, foundations and qualified plans (as described above). Class I shares are also offered to investment and institutional clients of Eaton Vance and its affiliates and certain persons affiliated with Eaton Vance and certain fund service providers. Purchases of Class I shares for International Equity Fund and Structured Emerging Markets Fund are subject to a 1% redemption fee if redeemed or exchanged within 90 days of settlement of purchase. Class I shares do not pay distribution or service fees. Returns on Class I shares generally are higher than returns on other classes because Class I has lower annual expenses.

Class R shares are offered at net asset value with no front-end sales charge to retirement plan clients of financial intermediaries who charge such clients an ongoing fee for advisory, investment, consulting or similar services. Retirement plan clients include pension plans (including tax-deferred retirement plans and profit-sharing plans), Individual Retirement Account rollovers and non-qualified deferred compensation programs. Class R shares pay distribution fees and service fees equal to 0.50% annually of average daily net assets. Returns on Class R shares are generally lower than returns on Class A shares because Class R has higher annual expenses than Class A.

Payments to Investment Dealers. In connection with sales of Fund shares, an investment dealer may receive sales charges and Fund distribution and service fees as described below. Sales charges, distribution fees and service fees paid to investment dealers vary by share class. In addition, the principal underwriter, out of its own resources, may make cash payments to certain investment dealers who provide marketing support, transaction processing and/or administrative services and, in some cases, include some or all Eaton Vance funds in specialized selling programs. Payments made by the principal underwriter to an investment dealer may be significant and are typically in the form of fees based on Fund sales, assets, transactions processed and/or accounts attributable to that investment dealer. Investment dealers also may receive amounts from the principal underwriter in connection with educational or due diligence meetings that include information concerning Eaton Vance funds. The principal underwriter may pay or allow other promotional incentives or payments to investment dealers to the extent permitted by applicable laws and regulations.

Certain investment dealers that maintain “street name” or omnibus accounts provide sub-accounting, recordkeeping and/ or administrative services to the Eaton Vance funds and are compensated for such services by the funds. As used in this prospectus, the term “investment dealer” includes any broker, dealer, bank (including bank trust departments), registered investment adviser, financial planner, retirement plan administrator, their designated intermediaries and any other firm having a selling, administration or similar agreement with the principal underwriter or its affiliates.

19

Sales Charges

Class A Front-End Sales Charge. Class A shares are offered at net asset value per share plus a sales charge that is determined by the amount of your investment. The current sales charge schedule is:

The principal underwriter may also pay commissions of up to 1.00% on sales of Class A shares made at net asset value to certain tax-deferred retirement plans.

Reducing or Eliminating Class A Sales Charges. Front-end sales charges on purchases of Class A shares may be reduced under the right of accumulation or under a statement of intention. To receive a reduced sales charge, you must inform your investment dealer or a Fund at the time you purchase shares that you qualify for such a reduction. If you do not let your investment dealer or the Fund know you are eligible for a reduced sales charge, you may not receive the discount to which you are otherwise entitled.

Under the right of accumulation, the sales charge you pay is reduced if the current market value of your holdings in a Fund or any other Eaton Vance fund (based on the current maximum public offering price) plus your new purchase total of $50,000 or more. Class A, Advisers Class, Class B, Class C, Class I and/or Class R shares of a Fund or other Eaton Vance funds, as well as shares of Eaton Vance Money Market Fund, owned by you may be included for this purpose. Shares of Eaton Vance Cash Management Fund and Eaton Vance Tax Free Reserves cannot be included under the right of accumulation. Shares owned by you, your spouse and children under age twenty-one may be combined for purposes of the right of accumulation, including shares held for the benefit of any of you in trust or fiduciary accounts (including retirement accounts) or omnibus or “street name” accounts. In addition, shares purchased and/or owned in a SEP, SARSEP and SIMPLE IRA plan may be combined for purposes of the right of accumulation for the plan and its participants. You may be required to provide documentation to establish your ownership of shares included under the right of accumulation (such as account statements for you, your spouse and children or marriage certificates, birth certificates and/or trust or other fiduciary-related documents).

Under a statement of intention, purchases of $50,000 or more made over a 13-month period are eligible for reduced sales charges. Shares eligible under the right of accumulation (other than those included in employer-sponsored retirement plans) may be included to satisfy the amount to be purchased under a statement of intention. Under a statement of intention, the principal underwriter may hold 5% of the dollar amount to be purchased in escrow in the form of shares registered in your name until you satisfy the statement or the 13-month period expires. A statement of intention does not obligate you to purchase (or a Fund to sell) the full amount indicated in the statement.

Class A shares are offered at net asset value (without a sales charge) to clients of financial intermediaries who charge an ongoing fee for advisory, investment, consulting or similar services. Such clients may include individuals, corporations, endowments and pension plans (including tax-deferred retirement plans and profit sharing plans). Class A shares also are offered at net asset value to investment and institutional clients of Eaton Vance and its affiliates; certain persons affiliated with Eaton Vance; and to certain fund service providers as described in the Statement of Additional Information; and in connection with the ReFlow liquidity program. Class A shares may also be purchased at net asset value pursuant to the reinvestment privilege and exchange privilege and when distributions are reinvested. See “Shareholder Account Features” for details.

20

Contingent Deferred Sales Charge. Each Class of shares with the exception of Class I shares and Class R shares is subject to a CDSC on certain redemptions. Class A shares purchased at net asset value in amounts of $1 million or more are subject to a 1.00% CDSC if redeemed within 18 months of purchase. Class C shares are subject to a 1.00% CDSC if redeemed within 12 months of purchase.

The sales commission payable to investment dealers in connection with sales of Class C shares is described under “Distribution and Service Fees” below.

CDSC Waivers. CDSCs are waived for certain redemptions pursuant to a Withdrawal Plan (see “Shareholder Account Features”) and for Class C shares, in connection with certain redemptions from tax-deferred retirement plans. The CDSC is also waived following the death of a beneficial owner of shares (a death certificate and other applicable documents may be required).

Distribution and Service Fees. Class A, Class C and Class R shares have in effect a plan under Rule 12b-1 that allows each Fund to pay distribution fees for the sale and distribution of shares (so-called “12b-1 fees”) and service fees for personal and/or shareholder account services. Class C shares pay distribution fees to the principal underwriter of 0.75% of average daily net assets annually. Class R shares of Dividend Income Fund pay distribution fees of 0.25% of average daily net assets. Although there is no present intention to do so, Dividend Income Fund could pay distribution fees on Class R shares of up to 0.50% annually upon Trustee approval. Because these fees are paid from Fund assets on an ongoing basis, they will increase your cost over time and may cost you more than paying other types of sales charges. The principal underwriter compensates investment dealers on sales of Class C shares (except exchange transactions and reinvestments) in an amount equal to 1% of the purchase price of the shares. After the first year, investment dealers also receive 0.75% of the value of Class C shares in annual distribution fees. Class C and Class R also pay service fees to the principal underwriter equal to 0.25% of average daily net assets annually. Class A shares pay distribution and service fees equal to 0.25% of average daily net assets annually. After the sale of shares, the principal underwriter receives the Class A distribution and service fees and the Class C service fees for one year and thereafter investment dealers generally receive them based on the value of shares sold by such dealers for shareholder servicing performed by such investment dealers. Distribution and service fees are subject to the limitations contained in the sales charge rule of the National Association of Securities Dealers, Inc.

More information about sales charges is available free of charge on the Eaton Vance website at www.eatonvance.com and in the Statement of Additional Information. Please consult the Eaton Vance website for any updates to sales charge information before making a purchase of Fund shares.

21

If you redeem shares, your redemption price will be based on the net asset value per share next computed after the redemption request is received. Your redemption proceeds will be paid in cash within seven days, reduced by the amount of any applicable CDSC and any federal income tax required to be withheld. Payments will be sent by mail unless you complete the Bank Wire Redemptions section of the account application.

If you recently purchased shares, the proceeds of a redemption will not be sent until the purchase check (including a certified or cashier’s check) has cleared. If the purchase check has not cleared, redemption proceeds may be delayed up to 15 days from the purchase date. If your account value falls below $750 (other than due to market decline), you may be asked either to add to your account or redeem it within 60 days. If you take no action, your account will be redeemed and the proceeds sent to you.

Class A shares and Class I shares of International Equity Fund and Structured Emerging Markets Fund are subject to a 1% redemption fee if redeemed or exchanged within 90 days of the settlement of the purchase. All redemption fees will be paid to the Fund. Redemptions of shares held by tax-deferred retirement plans, in proprietary fee-based programs sponsored by broker-dealers, or by Eaton Vance, its affiliated entities and accounts in which Eaton Vance or such an affiliate have a beneficial interest, as well as the redemption of shares acquired as the result of reinvesting distributions, are not subject to the redemption fee.

While redemption proceeds are normally paid in cash, redemptions may be paid by distributing marketable securities. If you receive securities, you could incur brokerage or other charges in converting the securities to cash.

22

Shareholder Account Features

Once you purchase shares, the transfer agent establishes an account for you.

Distributions. You may have your Fund distributions paid in one of the following ways:

Information about the Funds. From time to time, you may be mailed the following:

Each Fund will file with the Securities and Exchange Commission (“SEC”) a list of its portfolio holdings as of the end of the first and third fiscal quarters on Form N-Q. Each Fund’s annual and semiannual reports (as filed on Form N-CSR) and each Form N-Q may be viewed on the SEC’s website (www.sec.gov). The most recent fiscal and calendar quarter end holdings may also be viewed on the Eaton Vance website (www.eatonvance.com). Portfolio holdings information is filed with the SEC or posted on the Eaton Vance website approximately 60 days after the end of the quarter to which it relates. Each Fund also posts information about certain portfolio characteristics (such as top ten holdings and asset allocation) as of the most recent calendar quarter end on the Eaton Vance website approximately ten business days after the calendar quarter end.

The Eaton Vance funds have established policies and procedures with respect to the disclosure of portfolio holdings and other information concerning Fund characteristics. A description of these policies and procedures is provided in the Statement of Additional Information. Such policies and procedures regarding disclosure of portfolio holdings are designed to prevent the misuse of material, non-public information about the funds.

Withdrawal Plan. You may redeem shares on a regular monthly or quarterly basis by establishing a systematic withdrawal plan. Withdrawals will not be subject to any applicable CDSC if they are, in the aggregate, less than or equal to 12% annually of the greater of either the initial account balance or the current account balance. Because purchases of Class A shares are generally subject to an initial sales charge, Class A shareholders should not make withdrawals from their accounts while also making purchases. Because redemptions of Class A shares and Class I shares of International Equity Fund and Structured Emerging Markets Fund within 90 days of settlement of purchase are subject to a 1% redemption fee (including shares held in individual retirement accounts), shareholders should not make withdrawals pursuant to a Withdrawal Plan during that period.

Tax-Deferred Retirement Plans. All Classes of shares are available for purchase in connection with certain tax-deferred retirement plans. Call 1-800-262-1122 for information. Distributions will be invested in additional shares for all tax-deferred retirement plans.

Exchange Privilege. You may exchange your Fund shares for shares of the same Class of another Eaton Vance fund or, in the case of Class C shares, Eaton Vance Money Market Fund. Exchanges are made at net asset value (subject to any applicable redemption fee). If your shares are subject to a CDSC, the CDSC will continue to apply to your new shares at the same CDSC rate. For purposes of the CDSC, your shares will continue to age from the date of your original purchase of Fund shares.

23

Before exchanging, you should read the prospectus of the new fund carefully. If you wish to exchange shares, write to the transfer agent (see back cover for address) or call 1-800-262-1122. Periodic automatic exchanges are also available. The exchange privilege may be changed or discontinued at any time. You will receive 60 days’ notice of any material change to the privilege. This privilege may not be used for “market timing”. If an account (or group of accounts) makes more than two round-trip exchanges (exchanged from one fund to another and back again) within 12 months, it will be deemed to be market timing. As described under “Purchasing Shares”, the exchange privilege may be terminated for market timing accounts or for other reasons.

Reinvestment Privilege. If you redeem shares, you may reinvest at net asset value all or any portion of the redemption proceeds in the same class of shares of the Fund you redeem from, provided that the reinvestment occurs within 60 days of the redemption, and the privilege has not been used more than once in the prior 12 months. Under these circumstances your account will be credited with any CDSC paid in connection with the redemption. Any CDSC period applicable to the shares you acquire upon reinvestment will run from the date of your original share purchase. Reinvestment requests must be in writing. If you reinvest, your purchase will be at the next determined net asset value following receipt of your request.

Telephone and Electronic Transactions. You can redeem or exchange shares by telephone as described in this prospectus. In addition, certain transactions may be conducted through the Internet. The transfer agent and the principal underwriter have procedures in place to authenticate telephone and electronic instructions (such as using security codes or verifying personal account information). As long as the transfer agent and principal underwriter follow reasonable procedures, they will not be responsible for unauthorized telephone or electronic transactions and you bear the risk of possible loss resulting from these transactions. You may decline the telephone redemption option on the account application. Telephone instructions are recorded.

“Street Name” Accounts. If your shares are held in a “street name” account at an investment dealer, that dealer (and not the Fund or its transfer agent) will perform all recordkeeping, transaction processing and distribution payments. Because the Fund will have no record of your transactions, you should contact your investment dealer to purchase, redeem or exchange shares, to make changes in your account, or to obtain account information. You will not be able to utilize a number of shareholder features, such as telephone transactions, directly with a Fund. If you transfer shares in a “street name” account to an account with another investment dealer or to an account directly with a Fund, you should obtain historical information about your shares prior to the transfer.

Procedures for Opening New Accounts. To help the government fight the funding of terrorism and money laundering activities, federal law requires each Fund to obtain, verify and record information that identifies each person who opens a Fund account. When you open an account, the transfer agent or your investment dealer will ask you for your name, address, date of birth and other identifying information. You also may be asked to produce a copy of your driver’s license and other identifying documents. If a person fails to provide the information requested, any application by that person to open a new account will be rejected. Moreover, if the transfer agent or the investment dealer is unable to verify the identity of a person based on information provided by that person, it may take additional steps including, but not limited to, requesting additional information from the person, closing the person’s account or reporting the matter to the appropriate federal authorities. If your account is closed for this reason, your shares may be automatically redeemed. If the Fund’s net asset value has decreased since your purchase, you will lose money as a result of this redemption.

Account Questions. If you have any questions about your account or the services available, please call Eaton Vance Shareholder Services at 1-800-262-1122, or write to the transfer agent (see back cover for address).

Tax Information

Each Fund intends to pay dividends annually, except Dividend Income Fund which intends to pay dividends monthly, and to distribute any net realized capital gains (if any) annually. Distributions of income (other than qualified dividend income, which is described below) and net short-term capital gains will be taxable as ordinary income. Distributions of qualified dividend income and any long-term capital gains are taxable as long-term capital gains. Taxes on distributions of capital gains are determined by how long a Fund or Portfolio owned the investments that generated them, rather than how long a shareholder has owned his or her shares in a Fund. Different classes generally will distribute different amounts. A Fund’s distributions will be taxable as described above whether they are paid in cash or reinvested in additional shares. A portion of Equity Research Fund’s income distributions may be eligible for the dividends-received deduction for corporations.

For taxable years beginning on or before December 31, 2010, distributions of investment income designated by a Fund as derived from "qualified dividend income" will be taxed in the hands of individuals at rates applicable to long-term capital gains provided holding period and other requirements are met at both the shareholder and Fund level.

24

Investors who purchase shares at a time when a Fund’s net asset value reflects gains that are either unrealized or realized but undistributed will pay the full price for the shares and then may receive some portion of the purchase price back as a taxable distribution. Certain distributions paid in January will be taxable to shareholders as if received on December 31 of the prior year. A redemption of Fund shares, including an exchange for shares of another fund, is a taxable transaction.

A Fund’s investments in foreign securities may be subject to foreign withholding or other foreign taxes, which would decrease the Fund’s return on such securities. Under certain circumstances, shareholders of International Equity Fund and Structured Emerging Markets Fund may be entitled to claim a credit or deduction with respect to foreign taxes. In addition, investments in foreign securities or foreign currencies may increase or accelerate a Fund’s recognition of ordinary income and may affect the timing or amount of the Fund’s distributions.

The International Equity Fund intends to file an election each year which would require Fund shareholders to include in gross income thier pro rata share of qualified foreign income taxes paid by the Fund (even though such amounts are not received by the shareholders) and could allow Fund shareholders, provided certain requirements are met, to use their pro rata portion of such foreign income taxes as a foreign tax credit against their federal income taxes or, alternatively, for shareholders who itemize their tax deductions, to deduct their portion of the Fund’s foreign taxes paid in computing their taxable federal income.

Shareholders should consult with their advisers concerning the applicability of federal, state, local, foreign and other taxes to an investment.

25

Valuing Shares

Each Fund values its shares once each day only when the New York Stock Exchange is open for trading (typically Monday through Friday), as of the close of regular trading on the Exchange (normally 4:00 p.m. eastern time). The purchase price of Fund shares is their net asset value (plus a sales charge for Class A shares), which is derived from the value of its Portfolio holdings. When purchasing or redeeming Fund shares, your investment dealer must communicate your order to the principal underwriter by a specific time each day in order for the purchase price or the redemption price to be based on that day’s net asset value per share. It is the investment dealer’s responsibility to transmit orders promptly. Each Fund may accept purchase and redemption orders as of the time of their receipt by certain investment dealers (or their designated intermediaries).

The Trustees have adopted procedures for valuing investments and have delegated to the investment adviser the daily valuation of such investments. Most seasoned 30-year fixed-rate ^MBS are valued through the use of a matrix pricing system, which takes into account bond prices, yield differentials, anticipated prepayments and interest rates provided by dealers. Certain other MBS, including, but not limited to, collateralized mortgage obligations and adjustable rate mortgage-backed securities are valued by independent pricing services. The investment adviser uses independent pricing services to value most loans and other debt securities at their market value. In determining market value, the pricing service for loans considers information obtained from broker-dealers and the pricing service for debt obligations considers various factors and market information relating to debt ^ obligations .

In certain situations, the investment adviser may use the fair value of a security or loan if a security or loan is not priced by a pricing service, the pricing services’ price is deemed unreliable, or if events occur after the close of a securities market (usually a foreign market) and before the Portfolio values its assets that would materially affect net asset value. A security

22

that is fair valued may be valued at a price higher or lower than actual market quotations or the value determined by other funds using their own fair valuation procedures. Because foreign loans and securities may trade on days when Fund shares are not priced, ^ the value of securities held by a Fund or Portfolio can change on days when Fund shares cannot be redeemed. The investment adviser expects to use fair value pricing primarily when a security is not priced by a pricing service or a pricing service’s price is deemed unreliable. Eaton Vance has established a Valuation Committee that oversees the valuation of investments.

Purchasing Shares

You may purchase shares through your investment dealer or by mailing an account application form to the transfer agent (see back cover for address). You may request an account application by calling 1-800-262-1122. Your initial investment must be at least $1,000.

After your initial investment, additional investments ^may be made at any time by sending a check payable to the order of the Fund or the transfer agent directly to the transfer agent (see back cover for address)^ . Please include your name and account number and the name of the Fund and Class of shares with each investment.

You may make automatic investments in Class A, B and C shares of $50 or more each month or each quarter from your bank account. You can establish bank automated investing on the account application or by calling 1-800-262-1122. The minimum initial investment amount and Fund policy of redeeming accounts with low account balances are waived for bank automated investing accounts, certain group purchase plans (including ^ tax-deferred retirement and other pension plans and proprietary fee-based programs sponsored by by broker-dealers), the ReFlow liquidity program, and for persons affiliated with Eaton Vance and certain Fund service ^ providers (as described in the Statement of Additional Information) .

Purchase orders will be executed at the net asset value next determined after their receipt by a Fund. A Fund or your investment dealer must receive your purchase order no later than the close of regular trading on the New York Stock Exchange (normally 4:00 p.m. eastern time) in order for your purchase to be effected at that day’s net asset value. If you purchase shares through an investment dealer (which includes brokers, dealers and other financial institutions), that dealer may charge you a fee for executing the purchase for you. Each Fund may suspend the sale of its shares at any time and any purchase order may be refused.

Restrictions on Excessive Trading and Market Timing. The Funds are not intended for excessive trading or market timing. Market timers seek to profit by rapidly switching money into a fund when they expect the share price of the fund to rise and taking money out of the fund when they expect those prices to fall. By realizing profits through short-term trading, shareholders that engage in rapid purchases and sales or exchanges of a fund’s shares may dilute the value of shares held by long-term shareholders. Volatility resulting from excessive purchases and sales or exchanges of fund shares, especially involving large dollar amounts, may disrupt efficient portfolio management. In particular, excessive purchases and sales or exchanges of a fund’s shares may cause a fund to have difficulty implementing its investment strategies, may force the fund to sell portfolio securities at inopportune times to raise cash or may cause increased expenses (such as increased brokerage costs, realization of taxable capital gains without attaining any investment advantage or increased administrative costs).

A fund that invests in securities that are, among other things, thinly traded, traded infrequently or relatively illiquid (including Senior Loans owned by a Portfolio or other obligations not priced by a pricing service) is susceptible to the risk that the current market price for such securities may not accurately reflect current market values. A shareholder may seek to engage in short-term trading to take advantage of these pricing differences (commonly referred to as “price arbitrage”). In addition, because ^ each Portfolio (except Government Obligations Portfolio) may invest up to 25% of net assets in foreign securities, it may be susceptible to a time zone arbitrage strategy in which shareholders attempt to take advantage of Fund share prices that may not reflect developments in a foreign securities market that occur after the close of such market but prior to the pricing of Fund shares. The investment adviser is authorized to use the fair value of a security if prices are unavailable or are deemed unreliable (see “Valuing Shares”). The use of fair value pricing and the restrictions on excessive trading and market timing described below are intended to reduce a shareholder’s ability to engage in price or time zone arbitrage to the detriment of the Funds.

The Boards of Trustees of the Eaton Vance funds have adopted policies to discourage short-term trading and market timing and to seek to minimize their potentially detrimental effects. Pursuant to these policies, if an investor (through one or more accounts) makes more than two round-trip exchanges (exchanging from one fund to another fund and back again) within 12 months, it will be deemed to constitute market timing or excessive trading. Under the policies, each Fund or its principal underwriter will reject or cancel a purchase order, suspend or terminate the exchange privilege or terminate the ability of an investor to invest in the Eaton Vance funds if the Fund or the principal underwriter determines that a proposed

23

transaction involves market timing or excessive trading that it believes is likely to be detrimental to the Fund. Each Fund and its principal underwriter cannot ensure that they will be able to identify all cases of market timing and excessive trading, although they believe they have adequate procedures in place to attempt to do so. Each Fund or its principal underwriter may also reject or cancel any purchase order (including an exchange) from an investor or group of investors for any other reason. Decisions to reject or cancel purchase orders (including exchanges) in each Fund are inherently subjective and will be made in a manner believed to be in the best interest of a Fund’s shareholders. No Eaton Vance fund has any arrangement to permit market timing^ . Investments in each Fund by ReFlow in connection with the ReFlow liquidity program (which is described under "Investment Objectives & Principal Policies and Risks" above) are not subject to the two round trip limitation.

The Funds and the principal underwriter have provided guidance to financial intermediaries (such as banks, broker-dealers, insurance companies and retirement administrators) concerning the application of the Eaton Vance funds’ market timing and excessive trading policies to Fund shares held in omnibus accounts maintained and administered by such intermediaries, including guidance concerning situations where market timing or excessive trading is considered to be detrimental to a Fund. Each Fund or its principal underwriter may rely on a financial intermediary’s policy to restrict market timing and excessive trading if it believes that policy is likely to prevent market timing that is likely to be detrimental to each Fund. Such policy may be more or less restrictive than a Fund’s policy. Each Fund and the principal underwriter cannot ensure that these financial intermediaries will in all cases apply the policies of the Funds or their own policies, as the case may be, to accounts under their control.

Choosing a Share Class. Each Fund offers different classes of shares. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different sales charges and expenses and will likely have different share prices due to differences in class expenses. In choosing the class of shares that suits your investment needs, you should consider:

• how long you expect to own your shares;
• how much you intend to invest;
• the sales charge and total operating expenses associated with owning each class; and
• whether you qualify for a reduction or waiver of any applicable sales charges (see “Reducing or Eliminating Class A Sales Charges” under “Sales Charges” below).

Each investor’s considerations are different. You should speak with your investment dealer to help you decide which class of shares is best for you. Set forth below is a brief description of each class of shares offered by the Funds.

Class A shares are offered at net asset value plus a front-end sales charge of up to 4.75% (2.25% for Low Duration Fund). This charge is deducted from the amount you invest. The Class A sales charge is reduced for purchases of of $25,000 ($100,000 for Low Duration Fund) or more. The sales charge applicable to your purchase may be reduced under the right of accumulation or a statement of intention, which are described in “Reducing or Eliminating Class A Sales Charges” under “Sales Charges” below. Some investors may be eligible to purchase Class A shares at net asset value under certain circumstances, which are also described below. Purchases of Class A shares of High Income Fund are subject to a 1% redemption fee if redeemed within 90 days of the settlement of the purchase. Class A shares pay distribution and service fees equal to 0.25% annually of average daily net assets. ^Returns on Class A shares are generally higher than returns on the Fund’s other classes of shares because Class A has lower annual expenses than those classes.

Class B shares are offered at net asset value with no front-end sales charge. If you sell your Class B shares within six (four years for Low Duration Fund) years of purchase, you generally will be subject to a contingent deferred sales charge or “CDSC”. The amount of the CDSC applicable to a redemption of Class B shares decreases over six (four years for Low Duration Fund) years, as described in the CDSC schedule in “Contingent Deferred Sales Charge” under “Sales Charges” below. The CDSC is deducted from your redemption proceeds. Under certain circumstances, the Class B CDSC may be waived (such as in the case of the death of the shareholder). See “CDSC Waivers” under “Sales Charges” below. Class B shares pay distribution fees and service fees equal to 1.00% annually of average daily net assets. Returns on Class B shares are generally lower than returns on Class A shares because Class B has higher annual expenses than Class A. Class B shares will automatically convert to Class A shares after eight years. Because the sales charge applicable to Class A shares is reduced for larger purchases and Class A has lower operating expenses, purchasing Class B shares may not be appropriate if you are investing a large amount.

Orders for Class B shares of one or more Eaton Vance funds will be refused when the total value of the purchase (including the aggregate value of all ^ Eaton Vance fund shares held within the purchasing shareholder’s account)

24

is $100,000 or more. Investors considering cumulative purchases of $100,000 or more, or who, after a purchase of ^shares, would own shares of Eaton Vance funds with a current market value of $100,000 or more, should consider whether Class A shares would be more advantageous and consult their investment dealer.

Class C shares are offered at net asset value with no front-end sales charge. If you sell your Class C shares within ^ 12 months of purchase, you generally will be subject to a CDSC. The CDSC is deducted from your redemption proceeds. Under certain circumstances, the Class C CDSC may be waived (such as certain redemptions from tax-deferred retirement plan accounts). See “CDSC Waivers” under “Sales Charges” below. Class C shares pay distribution fees and service fees equal to 1.00% (0.85% for Low Duration Fund) annually of average daily net assets. ^ Returns on Class C shares are generally lower than returns on Class A shares because Class C has higher annual expenses than Class A.

Orders for Class C shares of one or more Eaton Vance funds will be refused when the total value of the purchase (including the aggregate value of all ^ Eaton Vance fund shares held within the purchasing shareholder’s account) is $1,000,000 or more. Investors considering cumulative purchases of $1,000,000 or more, or who, after a purchase of ^shares, would own shares of Eaton Vance funds with a current market value of $1,000,000 or more, should consider whether Class A shares would be more advantageous and consult their investment dealer.

Class R shares are offered at net asset value with no front-end sales charge to retirement plan clients of financial intermediaries who charge such clients an ongoing fee for advisory, investment, consulting or similar services. Retirement plan clients include pension plans (including tax-deferred ^ retirement plans and profit-sharing plans), Individual Retirement Account rollovers and non-qualified deferred compensation programs. Class R shares pay distribution fees and service fees equal to 0.50% annually of average daily net assets. Returns on Class R shares are generally lower than returns on Class A shares because Class R has higher annual expenses than Class A.

Payments to Investment Dealers. In connection with sales of Fund shares, an investment dealer may receive sales charges and Fund distribution and service fees as described below. Sales charges, distribution fees and service fees paid to investment dealers vary by share class. In addition, the principal underwriter, out of its own resources, may make cash payments to certain investment dealers who provide marketing support, transaction processing and/or administrative services and, in some cases, include some or all Eaton Vance funds in ^specialized selling programs. Payments made by the principal underwriter to an investment dealer may be significant and are typically in the form of fees based on Fund sales, assets, transactions processed and/or accounts attributable to that investment dealer. Investment dealers also may receive amounts from the principal underwriter in connection with educational or due diligence meetings that include information concerning Eaton Vance funds. The principal underwriter may pay or allow other promotional incentives or payments to investment dealers to the extent permitted by applicable laws and regulations.

Certain investment dealers that maintain “street name” or omnibus accounts provide sub-accounting, recordkeeping and/ or administrative services to the Eaton Vance funds and are compensated for such services by the funds. As used in this prospectus, the term “investment dealer” includes any broker, dealer, bank (including bank trust departments), registered investment adviser, financial planner, retirement plan administrator, their designated intermediaries and any other firm having a selling, administration or similar agreement with the principal underwriter or its affiliates.

25

*Because the offering price per share is rounded to two decimal places, the actual sales charge you pay on a purchase of Class A shares may be more or less than your total purchase amount multiplied by   the applicable sales charge percentage. **No sales charge is payable at the time of purchase on investments of $1 million or more. A CDSC of 1.00% will be imposed on such investments (as described below) in the event of redemptions within   ^ 18 months of purchase.

^

The principal underwriter may also pay commissions of up to 1.00% on sales of Class A shares made at net asset value to certain tax-deferred retirement plans.

Reducing or Eliminating Class A Sales Charges. Front-end sales charges on purchases of Class A shares may be reduced under the right of accumulation or under a statement of intention. To receive a reduced sales charge, you must inform your investment dealer or a Fund at the time you purchase shares that you qualify for such a reduction. If you do not let your investment dealer or the Fund know you are eligible for a reduced sales charge, you may not receive the discount to which you are otherwise entitled.

Under the right of accumulation, the sales charge you pay is reduced if the current market value of your holdings in a Fund or any other Eaton Vance fund (based on the current maximum public offering price) plus your new purchase total of of $25,000 ($100,000 for Low Duration Fund) or more. Class A, Advisers Class, Class B, Class C, Class I and/or Class R shares of the Fund or other Eaton Vance funds, as well as shares of Eaton Vance Money Market Fund, owned by you may be included for this purpose. Shares of Eaton Vance Cash Management Fund and Eaton Vance Tax Free Reserves cannot be included under the right of accumulation. Shares owned by you, your spouse and children under age twenty-one may be combined for purposes of the right of accumulation, including shares held for the benefit of any of you in trust or fiduciary accounts (including retirement accounts) or omnibus or “street name” accounts . In addition, shares purchased and/or owned in a SEP, SARSEP and SIMPLE IRA plan may be combined for purposes of the right of accumulation for the plan and its participants . You may be required to provide documentation to establish your ownership of shares included under the right of accumulation (such as account statements for you, your spouse and children or marriage certificates, birth certificates and/or trust or other fiduciary-related documents).

Under a statement of intention, purchases of of $25,000 ($100,000 for Low Duration Fund) or more made over a 13-month period are eligible for reduced sales charges. Shares eligible under the right of accumulation (other than those included in employer-sponsored retirement plans) may be included to satisfy the amount to be purchased under a statement of intention. Under a statement of intention, the principal underwriter may hold 5% of the dollar amount to be purchased in escrow in the form of shares registered in your name until you satisfy the statement or the 13-month period expires. A statement of intention does not obligate you to purchase (or a Fund to sell) the full amount indicated in the statement.

Class A shares are offered at net asset value (without a sales charge) to clients of financial intermediaries who charge an ongoing fee for advisory, investment, consulting or similar services. Such clients may include individuals, ^ corporations, endowments, foundations and pension plans (including tax-deferred retirement plans and profit sharing plans) . Class A shares also are offered at net asset value to investment and institutional clients of Eaton Vance and its affiliates; certain persons affiliated with Eaton Vance; ^ to certain fund service providers as described int eh statement of Additional Inforamtion; and in connection with the ReFlow liquidity program. Class A shares may also be purchased at net asset value pursuant to the reinvestment privilege and exchange privilege and when distributions are reinvested. See “Shareholder Account Features” for details^.

Contingent Deferred Sales Charge. ^Class A, Class B and Class C shares are ^subject to a CDSC on certain redemptions. Class A shares purchased at net asset value in amounts of $1 million or more ^are subject to a 1.00% CDSC if redeemed within 18 months of purchase^. Class C shares are subject to a 1.00% CDSC if redeemed within 12 months of purchase^ . Class B shares are subject to the following CDSC schedule:

26

^ CDSCs are based on the lower of the net asset value at the time of purchase or at the time of redemption. Shares acquired through the reinvestment of distributions are exempt from the CDSC. Redemptions are made first from shares that are not subject to a CDSC.

The sales commission payable to investment dealers in connection with sales of Class B and Class C shares is described under “Distribution and Service Fees” below.

CDSC Waivers. CDSCs are waived for certain redemptions pursuant to a Withdrawal Plan (see “Shareholder Account Features”) and, for Class B and Class C, in connection with certain redemptions from tax-deferred retirement plans. Call 1-800-262-1122 for details. The ^CDSC is also waived following the death of a beneficial owner of shares (a death certificate and other applicable documents may be required).

Conversion Feature. After eight years, ^ Diversified Income Fund, Government Obligations Fund and High Income Fund Class B shares automatically convert to ^ Class A shares. ^ After four years, Class B shares of Low Duration Fund automatically convert to Class A shares. Shares of the Funds acquired through the reinvestment of distributions convert in proportion to shares not so acquired.

Distribution and Service Fees. Class A, Class B, Class C and Class R shares have in effect plans under Rule 12b-1 that allow each Fund to pay distribution fees for the sale and distribution of shares (so-called “12b-1 fees”^ ) and service fees for personal and/or shareholder account services . Class B and Class C shares pay distribution fees to the principal underwriter of 0.75% (0.60% for Low Duration Fund’s Class C shares) of average daily net assets annually. Class R shares of Government Obligations Fund pay a distribution fee at an annual rate of 0.25% of average daily net assets. Although there is no present intention to do so, Class R shares of Government Obligations Fund could pay distribution fees of up to 0.50% annually upon Trustee approval. Because these fees are paid from Fund assets on an ongoing basis, they will increase your cost over time and may cost you more than paying other types of sales charges. The principal underwriter compensates investment dealers on sales of Class B and Class C shares (except exchange transactions and reinvestments) in an amount equal to 4% (3% for Low Duration Fund) and 1%, respectively, of the purchase price of the shares. After the first year, investment dealers also receive 0.75% (0.50 ^ % for Low Duration Fund) of the value of Class C shares in annual distribution fees . Class B, Class C and Class R shares pay service fees to the principal underwriter equal to 0.25% of average daily net assets annually. Class A shares pay distribution and service fees equal to 0.25% of average daily net assets annually . After the sale of shares, the principal underwriter typically receives Class A distribution and service fees and the Class B and Class C service fees for one year and thereafter investment dealers generally receive them based on the value of shares sold by such dealers for shareholder servicing performed by such investment dealers. After the sale of Class R shares, the principal underwriter generally pays service fees to investment dealers based on the value of shares sold by such dealers. Distribution and service fees are subject to the limitations contained in the sales charge rule of the National Association of Securities Dealers, Inc.

27

Redeeming Shares You can redeem shares in any of the following ways:

If you redeem shares, your redemption price will be based on the net asset value per share next computed after the redemption request is received. Your redemption proceeds will be paid in cash within seven days, reduced by the amount of ^ any applicable CDSC and/or redemption fee and any federal income tax required to be withheld. Payments will be sent by mail unless you complete the Bank Wire Redemptions section of the account application^ .

If you recently purchased shares, the proceeds of a redemption will not be sent until the purchase check (including a certified or cashier’s check) has cleared. ^If the purchase check has not cleared, redemption proceeds may be delayed up to 15 days from the purchase date. If your account value falls below $750 (other than due to market decline), you may be asked either to add to your account or redeem it within 60 days. If you take no action, your account will be redeemed and the proceeds sent to you^ .

High Income Fund Class A shares ^are subject to a 1% redemption fee if redeemed or exchanged within 90 days of the settlement of the purchase. All redemption fees will be paid to the Fund. Redemptions of shares held by ^ tax-deferred retirement plans, in proprietary fee-based programs sponsored by broker-dealers, or by Eaton Vance, its affiliated entities and accounts in which Eaton Vance or such an affiliate have a beneficial interest, as well as the redemption of shares acquired as the result of reinvesting distributions, are not subject to the redemption fee.

While redemption proceeds are normally paid in cash, redemptions may be paid by distributing marketable securities. If you receive securities, you could incur brokerage or other charges in converting the securities to cash.

28

Shareholder Account Features

Once you purchase shares, the transfer agent establishes ^ an account for you. ^

Distributions. You may have your Fund distributions paid in one of the following ways:

Information about the Funds. From time to time, you may be mailed the following:

•Semiannual and annual reports containing a list of portfolio holdings as of the end of the second and fourth fiscal quarters, respectively, performance information and financial statements.

•Periodic account statements, showing recent activity and total share balance.

•Form 1099 and tax information needed to prepare your income tax returns.

•Proxy materials, in the event a shareholder vote is required.

•Special notices about significant events affecting your Fund.

Each Fund will file with the Securities and Exchange Commission (“SEC”) a list of its portfolio holdings as of the end of the first and third fiscal quarters on Form N-Q. Each Fund’s annual and semiannual reports (as filed on Form N-CSR) and each Form N-Q may be viewed on the SEC’s website (www.sec.gov). The most recent fiscal and calendar quarter end holdings may also be viewed on the Eaton Vance website (www.eatonvance.com). Portfolio holdings information is filed with the SEC or posted on the Eaton Vance website approximately 60 days after the end of the quarter to which it relates. Each Fund also posts information about certain portfolio characteristics (such as top ten holdings and asset allocation) as of the most recent calendar quarter end on the Eaton Vance website approximately ten business days after the calendar quarter end.

The Eaton Vance funds have established policies and procedures with respect to the disclosure of portfolio holdings and other information concerning Fund characteristics. A description of these policies and procedures is provided in the Statement of Additional Information. Such policies and procedures regarding disclosure of portfolio holdings are designed to prevent the misuse of material, non-public information about the funds.

Withdrawal Plan. ^ You may redeem shares on a regular monthly or quarterly basis by establishing a systematic withdrawal plan. Withdrawals will not be subject to any applicable CDSC if they are, in the aggregate, less than or equal to 12% annually of the greater of either the initial account balance or the current account balance. ^Because purchases of Class A shares are generally subject to an initial sales charge, Class A shareholders should not make withdrawals from their accounts while also making purchases. Because redemptions of High Income Fund Class A shares within 90 days of the settlement of the purchase are subject to a 1% redemption fee (including shares held in individual retirement accounts), shareholders should not make withdrawals pursuant to a Withdrawal Plan during that period.

Tax-Deferred Retirement Plans. Class A, Class C and Class R shares are available for purchase in connection with certain tax-deferred retirement plans. Call 1-800-262-1122 for information. Distributions will be invested in additional shares for all tax-deferred retirement plans.

Exchange Privilege. You may exchange your Fund shares for shares of the same Class of another Eaton Vance fund, or, in the case of Class B and Class C shares, Eaton Vance Money Market Fund. Exchanges are made at net asset value. If your shares are subject to a CDSC, the CDSC will continue to apply to your new shares at the same CDSC rate. For purposes of the CDSC, your shares will continue to age from the date of your original purchase of Fund shares.

Before exchanging, you should read the prospectus of the new fund carefully. If you wish to exchange shares, write to the transfer agent (see back cover for address) or call 1-800-262-1122. Periodic automatic exchanges are also available. The exchange privilege may be changed or discontinued at any time. You will receive 60 days’ notice of any material change to the privilege. This privilege may not be used for “market timing”. If an account (or group of accounts) makes more than

29

two round-trip exchanges (exchanged from one fund to another and back again) within 12 months, it will be deemed to be market timing. As described under “Purchasing Shares”, the exchange privilege may be terminated for market timing accounts or for other reasons.

Reinvestment Privilege. If you redeem shares, you may reinvest at net asset value all or any portion of the redemption proceeds in the same class of shares of ^ a Fund you redeem ^ from, provided that the reinvestment occurs within 60 days of the redemption, and the privilege has not been used more than once in the prior 12 months. Under these circumstances your account will be credited with any CDSC paid in connection with the redemption. Any CDSC period applicable to the shares you acquire upon reinvestment will run from the date of your original share purchase. Reinvestment requests must be in writing. If you reinvest, ^ your purchase will be ^at the next determined net asset value following receipt of your request.

Telephone and Electronic Transactions. You can redeem or exchange shares by telephone as described in this prospectus. In addition, certain transactions may be conducted through the Internet. The transfer agent and the principal underwriter have procedures in place to authenticate telephone and electronic instructions (such as using security codes or verifying personal account information). As long as the transfer agent and principal underwriter follow reasonable procedures, they will not be responsible for unauthorized telephone or electronic transactions and you bear the risk of possible loss resulting from these transactions. You may decline the telephone redemption option on the account application. Telephone instructions are ^recorded.

“Street Name” Accounts. If your shares are held in a “street name” account at an investment dealer, that dealer (and not the Fund or its transfer agent) will perform all recordkeeping, transaction processing and distribution payments. Because the Fund will have no record of your transactions, you should contact your investment dealer to purchase, redeem or exchange shares, to make changes in your account, or to obtain account information. You will not be able to utilize a number of shareholder features, such as telephone transactions, directly with ^ a Fund. ^ If you transfer ^shares in a “street name” account to an account with another investment dealer or to an account directly with ^ a Fund, you ^ should obtain historical information about your shares prior to the transfer. ^

Procedures for Opening New Accounts. To help the government fight the funding of terrorism and money laundering activities, federal law requires each Fund to obtain, verify and record information that identifies each person who opens a Fund account. When you open an account, the transfer agent or your investment dealer will ask you for your name, address, date of birth and other identifying information. You also may be asked to produce a copy of your driver’s license and other identifying documents. If a person fails to provide the information requested, any application by that person to open a new account will be rejected. Moreover, if the transfer agent or the investment dealer is unable to verify the identity of a person based on information provided by that person, it may take additional steps including, but not limited to, requesting additional information from the person, closing the person’s account or reporting the matter to the appropriate federal authorities. If your account is closed for this reason, your shares may be automatically redeemed. If the Fund’s net asset value has decreased since your purchase, you will lose money as a result of this redemption.

Account Questions. If you have any questions about your account or the services available, please call Eaton Vance Shareholder Services at 1-800-262-1122, or write to the transfer agent (see back cover for address).

Tax Information

Each Fund declares dividends daily and ordinarily pays distributions monthly. Different Classes will distribute different dividend amounts. Your account will be credited with dividends beginning on the business day after the day when the funds used to purchase your Fund shares are collected by the transfer agent. Distributions of income and net short-term capital gains will be taxable as ordinary income. Distributions of any long-term capital gains are taxable as long-term capital gains. Each Fund expects that its distributions will consist primarily of ordinary income. Taxes on distributions of capital gains are determined by how long a Portfolio owned the investments that generated them, rather than how long a shareholder has owned his or her shares in a Fund. A ^Fund’s distributions will be taxable as described above whether they are paid in cash or reinvested in additional shares^ . A portion of High Income Fund’s distributions may be eligible for the dividends received deduction for corporations.

Investors who purchase shares at a time when a Fund’s net asset value reflects gains that are either unrealized or realized but undistributed will pay the full price for the shares and then may receive some portion of the purchase price back as a taxable distribution. Certain distributions paid in January will be taxable to shareholders as if received on December 31 of the prior year. A redemption of Fund shares, including an exchange for shares of another fund, is a taxable transaction.

A Portfolio’s investments in foreign securities may be subject to foreign withholding taxes, or other foreign taxes with respect to income (possibly including, in some cases, capital gains) which would decrease ^ Fund returns on such securities. Shareholders will generally not be entitled to claim a credit or deduction with respect to foreign taxes paid by a Portfolio. In addition, investments in foreign securities or foreign currencies may increase or accelerate ^ a Fund’s recognition of ordinary income and may affect the timing or amount of ^ Fund distributions.

Shareholders should consult with their advisers concerning the applicability of federal, state, local and other taxes to an investment.
