Valuing Shares

The 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 through an investment dealer, your investment dealer must ^

8

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. The 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. The investment adviser uses an independent pricing service 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 a loan is not priced by a pricing service, the pricing service’s 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 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 trade on days when Fund shares are not priced, the value of securities held by the Fund 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

Advisers Class, Class A, Class B and Class C

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 and other pension plans and proprietary fee-based programs sponsored by broker-dealers), and for persons affiliated with Eaton Vance and certain Fund service providers (as described in the Statement of Additional Information).

Purchases will be executed at the net asset value next determined after their receipt in good order by the Fund’s transfer agent. The Fund’s transfer agent or your investment dealer must receive your purchase in good order no later than the close of regular trading on the New York Stock Exchange (normally 4:00 p.m. eastern time) for your purchase to be effected at that day’s net asset value. Advisers Class shares are only offered to certain types of investors as described under "Choosing a Share Class" below. 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. The 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 (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services , or (ii) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform . 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). The initial ^

9

^ minimum ^ investment ^ also is waived for individual accounts of a financial intermediary that charges an ongoing fee for its services or offers Class I shares through a no-load network or platform ( in each case, as described ^ above ), 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 make an initial investment by wire, you must telephone the Fund Order Department at 1-800-262-1122 to advise of your action and to be assigned an account number. An account application form then 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.

Purchases will be executed at the net asset value next determined after their receipt in good order by the Fund’s transfer agent. The Fund’s transfer agent or your investment dealer must receive your purchase in good order no later than the close of regular trading on the New York Stock Exchange (normally 4:00 p.m. eastern time) 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. The 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 Fund is 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 all or a portion of its assets in foreign securities 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. In addition, a fund that invests in securities that are, among other things, thinly traded, traded infrequently or relatively illiquid (including certain Senior Loans owned by the Portfolio or other obligations not valued by the 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”). 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, the redemption fee applicable to Advisers Class shares, Class A shares and Class I shares, 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 Fund.

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, the 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. The 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. The 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 ^ the 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.

10

The Fund 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 the Fund. The 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 the Fund. Such policy may be more or less restrictive than the Fund’s policy. The Fund and the principal underwriter cannot ensure that these financial intermediaries will in all cases apply the policies of the Fund or their own policies, as the case may be, to accounts under their control.

Choosing a Share Class. The 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 Fund.

Advisers Class shares are offered at net asset value 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). Advisers Class 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 Advisers Class shares are subject to a 1% redemption fee if redeemed or exchanged within 90 days of settlement of purchase. Advisers Class shares pay distribution and service fees equal to 0.25% annually of average daily net assets. Distributions on Advisers Class shares are generally higher than distributions paid by Class B and Class C shares because Advisers Class has lower annual expenses than Class B and Class C.

Class A shares are offered at net asset value plus a front-end sales charge of up to 2.25% . This charge is deducted from the amount you invest. The Class A sales charge is reduced for purchases of $100,000 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 are subject to a 1% redemption fee if redeemed or exchanged within 90 days of settlement of purchase. Class A shares pay distribution and service fees of 0.25% annually of average daily net assets^. Returns on Class A shares are generally higher than returns on Class B and Class C shares because Class A has lower annual expenses than Class B and Class C^

Class B shares are offered at net asset value with no front-end sales charge. If you sell your Class B shares within four 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 four 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 0.60% 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 automatically convert to Class A shares eight years after purchase. 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.

11

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) 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 ^ one year 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 0.75% 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 (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services , or (ii) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform . 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 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.

Payments to Investment Dealers. In addition to payments disclosed under "Sales Charges" below, 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 preferred or 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.

12

*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 Advisers Class or 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 the 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 at the time of purchase, you will not receive the discount to which you may otherwise be entitled.

Under the right of accumulation, the sales charge you pay is reduced if the current market value of your holdings in the Fund or any other Eaton Vance fund (based on the current maximum public offering price) plus your new purchase total $100,000 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 omnibus or “street name” accounts. In addition, shares held in a trust or fiduciary account of which any of the foregoing persons is the sole beneficiary (including retirement accounts) may be combined for purposes of the right of accumulation. Shares purchased and/or owned in a SEP, SARSEP and SIMPLE IRA plan also 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 $100,000 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 the 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 (i) charge an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the principal underwriter to offer Class A shares through a no-load network or platform. Such clients may include individuals,

13

^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; and to certain fund service providers as described in the Statement of Additional Information. 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 one year ^of purchase. Class B shares are subject to the following CDSC schedule:

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 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).

Class B Conversion Feature. After eight years, Class B shares automatically convert to Class A shares. Class B shares acquired through the reinvestment of distributions convert in proportion to shares not so acquired.

Distribution and Service Fees. Advisers Class, Class A, Class B and Class C shares have in effect plans under Rule 12b-1 that allows the 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 0.40% and 0.60%, respectively, of average daily net assets annually. 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 3% and 1%, respectively, of the purchase price of the shares. After the first year, investment dealers also receive 0.60% of the value of Class C shares in annual distribution fees. Class B and Class C also pay service fees to the principal underwriter equal to 0.20% and 0.15%, respectively, of average daily net assets annually. Advisers Class and Class A shares pay distribution and service fees to the principal underwriter equal to 0.25% of average daily net assets annually. After the sale of Class A, Class B and Class C shares, the principal underwriter receives the 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. Although there is no present intention to do so, Class C shares could pay service fees of up to 0.25% annually upon Trustee approval. Distribution and service fees are subject to the limitations contained in the sales charge rule of the Financial Industry Regulatory Authority.

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.

14

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 in good order by ^ the Fund’s transfer agent. 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. However, if you have given complete written authorization in advance, you may request that the redemption proceeds be wired directly to your bank account. The bank designated may be any bank in the United States. The request may be made by calling 1-800-262-1122 or by sending a signature guaranteed letter of instruction to the transfer agent (see back cover for address) . Corporations, trusts and other entities may need to provide additional documentation . You may be required to pay the costs of such transaction by ^ the Fund or your bank. No costs are currently charged by ^ the Fund. The Fund may suspend or terminate the expedited payment procedure upon at least 30 ^ days’ notice.

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.

Advisers Class, Class A and Class I shares of the 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 ^ financial intermediaries , 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.

15

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

The 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. The 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 that is filed with the SEC is posted on the Eaton Vance website approximately 60 days after the end of the quarter to which it relates. Portfolio holdings information as of each calendar quarter end is posted to the website 30 days after such quarter end. ^The 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 Advisers Class, Class A and Class I 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. Advisers Class, Class A, Class C and Class I 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 (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.

16

Before exchanging, you should read the prospectus of the new fund carefully. Exchanges are subject to the terms applicable to purchases of the new fund’s shares as set forth in its prospectus. 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 ^ redeemed 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 . At the time of a reinvestment, you or your financial intermediary must notify the Fund or the transfer agent that you are reinvesting redemption proceeds in accordance with this privilege . 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 the Fund. If you transfer shares in a “street name” account to an account with another investment dealer or to an account directly with the 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 the Fund to obtain, verify and record information that identifies each person who opens a Fund account, and the Fund has designated an anti-money laundering compliance officer. 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

The Fund declares dividends daily and ordinarily pays distributions monthly. Any net realized capital gains will be distributed annually. Your account will be credited with dividends beginning on the business day after the day when the funds used to purchase your shares are collected by the transfer agent. The Fund expects that its distributions will consist primarily of taxable ordinary income.

Distributions of income and net short-term capital gains will be taxable as ordinary income. Distributions of any long-term capital gains will be taxable as long-term capital gains. Taxes on distributions of capital gains are determined by how long the Portfolio owned the investments that generated them, rather than how long a shareholder has owned his or her shares in the Fund. The Fund’s distributions are taxable as described above whether they are paid in cash or reinvested in additional shares. A portion of the Fund’s distributions may be eligible for the dividends-received deduction for corporations.

Investors who purchase shares at a time when the Fund’s net asset value reflects gains that are either unrealized or realized but not distributed 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 ^ may 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.

The Portfolio’s investments in foreign securities or loans 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 generally will not be entitled to claim a credit or deduction with respect to foreign taxes paid by the Portfolio. In addition, investments in foreign securities or loans or foreign currencies may increase or accelerate the 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.

CALCULATION OF NET ASSET VALUE

The net asset value of the Portfolio is computed by State Street (as agent and custodian for the Portfolio) by subtracting the liabilities of the Portfolio from the value of its total assets. The Fund and Portfolio will be closed for business and will not price their respective shares or interests on the following business holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Each investor in the Portfolio, including the Fund, may add to or reduce its investment in the Portfolio on each day the New York Stock Exchange (the “Exchange”) is open for trading (“Portfolio Business Day”) as of the close of regular trading on the Exchange (the “Portfolio Valuation Time”). The value of each investor’s interest in the Portfolio will be determined by multiplying the net asset value of the Portfolio by the percentage, determined on the prior Portfolio Business Day, which represented that investor’s share of the aggregate interests in the Portfolio on such prior day. Any additions or withdrawals for the current Portfolio Business Day will then be recorded. Each investor’s percentage of the aggregate interest in the Portfolio will then be recomputed as a percentage equal to a fraction (i) the numerator of which is the value of such investor’s investment in the Portfolio as of the Portfolio Valuation Time on the prior Portfolio Business Day plus or minus, as the case may be, the amount of any additions to or withdrawals from the investor’s investment in the Portfolio on the current Portfolio Business Day and (ii) the denominator of which is the aggregate net asset value of the Portfolio as of the Portfolio Valuation Time on the prior Portfolio Business Day plus or minus, as the case may be, the amount of the net additions to or withdrawals from the aggregate investment in the Portfolio on the current Portfolio Business Day by all investors in the Portfolio. The percentage so determined will then be applied to determine the value of the investor’s interest in the Portfolio for the current Portfolio Business Day.

Senior Loans ^ for which reliable market quotations are readily available ^are valued on the basis of prices furnished by an independent pricing service. Other Senior Loans are valued at ^fair value by the investment ^ adviser under procedures approved by the Trustees . In ^fair ^ valuing a Senior Loan, the investment adviser ^ utilizes one or more of the ^ following techniques: (i^) ^a matrix pricing approach that considers the yield on the Senior Loan relative to yields on other loan interests issued by companies of comparable credit quality^ ; (^ ii ) a comparison of the value of the borrower’s outstanding equity and debt to that of comparable public companies; (^ iii ) a discounted cash flow analysis; or (^ iv ) when the investment adviser believes it is likely that a borrower will be liquidated or sold, an analysis of the terms of such liquidation or sale. In certain cases, the investment adviser will use a combination of analytical methods to determine fair value, such as when only a portion of a borrower’s assets are likely to be sold. In conducting its assessment and analyses for purposes of determining fair value of a Senior Loan, the investment adviser will use its discretion and judgment in considering and appraising ^ relevant factors^. The portfolio managers of other funds managed by Eaton Vance that invest in Senior Loans may not possess the same information about a Senior Loan borrower as the portfolio managers of the Portfolio. At times, the fair value of a Senior Loan determined by the portfolio managers of other funds managed by Eaton Vance that invest in Senior Loans may vary from the fair value of the same Senior Loan determined by the portfolio managers of the Portfolio. The fair value of each Senior Loan is periodically reviewed and approved by the investment adviser’s Valuation Committee and by the Trustees based upon procedures approved by the Trustees. Junior Loans are valued in the same manner as Senior Loans.

Debt obligations (other than short-term obligations maturing in sixty days or less), including listed securities and securities for which price quotations are available and forward contracts, will normally be valued on the basis of market valuations furnished by dealers or pricing services. Financial futures contracts listed on commodity exchanges and exchange-traded options are valued at closing settlement prices. Over-the-counter options are valued at the mean between the bid and asked prices provided by dealers. Marketable securities listed in the NASDAQ Global or Global Select Market System are valued at the NASDAQ official closing price. The value of interest rate swaps will be based upon a dealer quotation. Short-term obligations and money market securities maturing in sixty days or less are valued at amortized cost which approximates value. Investments for which reliable market quotations are unavailable are valued at fair value using methods determined in good faith by or at the direction of the Trustees of the Portfolio. Occasionally, events affecting the value of foreign securities may occur between the time trading is completed abroad and the close of the Exchange which will not be reflected in the computation of the Portfolio’s net asset value (unless the Portfolio deems that such event would materially affect its net asset value in which case an adjustment would be made and reflected in such computation). The Portfolio may rely on an independent fair valuation service in making any such adjustment to the value of a foreign equity security.

PURCHASING AND REDEEMING SHARES

Additional Information About Purchases. Fund shares are offered for sale only in states where they are registered. Fund shares are continuously offered through investment dealers which have entered into agreements with the principal underwriter. Shares of the Fund are sold at the offering price, which is the net asset value plus the initial sales charge, if any. The Fund receives the net asset value. The principal underwriter receives the sales charge, all or a portion of which may be reallowed to the investment dealers responsible for selling Fund shares. The sales charge table in the prospectus is applicable to purchases of the Fund alone or in combination with purchases of certain other funds offered by the principal underwriter, made at a single time by (i) an individual, or an individual, his or her spouse and their children under the age of twenty-one, purchasing shares for his or their own account, and (ii) a trustee or other fiduciary purchasing shares for a single trust estate or a single fiduciary account. The table is also presently applicable to (1) purchases of Class A shares pursuant to a written Statement of Intention; or (2) purchases of Class A shares pursuant to the Right of Accumulation and declared as such at the time of purchase. See “Sales Charges”.

In connection with employee benefit or other continuous group purchase plans, the Fund may accept initial investments of less than the minimum investment amount on the part of an individual participant. In the event a shareholder who is a participant of such a plan terminates participation in the plan, his or her shares will be transferred to a regular individual account. However, such account will be subject to the right of redemption by the Fund as described below.

Suspension of Sales. The Trust may, in its absolute discretion, suspend, discontinue or limit the offering of one or more of its classes of shares at any time. In determining whether any such action should be taken, the Trust’s management intends to consider all relevant factors, including (without limitation) the size of the Fund or class, the investment climate and market conditions, the volume of sales and redemptions of shares, and (if applicable) the amount of uncovered distribution charges of the principal underwriter. The Advisers Class, Class A, Class B and Class C Distribution Plans may continue in effect and payments may be made under the Plans following any such suspension, discontinuance or limitation of the offering of shares; however, there is no contractual obligation to continue any Plan for any particular period of time. Suspension of the offering of shares would not, of course, affect a shareholder’s ability to redeem shares.

23

Additional Information About Redemptions. The right to redeem shares of the Fund can be suspended and the payment of the redemption price deferred when the Exchange is closed (other than for customary weekend and holiday closings), during periods when trading on the Exchange is restricted as determined by the SEC, or during any emergency as determined by the SEC which makes it impracticable for the Portfolio to dispose of its securities or value its assets, or during any other period permitted by order of the SEC for the protection of investors.

Due to the high cost of maintaining small accounts, the Trust reserves the right to redeem accounts with balances of less than $750. Prior to such a redemption, shareholders will be given 60 days’ written notice to make an additional purchase. However, no such redemption would be required by the Trust if the cause of the low account balance was a reduction in the net asset value of shares. No CDSC will be imposed with respect to such involuntary redemptions.

While normally payments will be made in cash for redeemed shares, the Trust, subject to compliance with applicable regulations, has reserved the right to pay the redemption price of shares of the Fund, either totally or partially, by a distribution in kind of readily marketable securities withdrawn from the Portfolio. The securities so distributed would be valued pursuant to the valuation procedures described in this SAI. If a shareholder received a distribution in kind, the shareholder could incur brokerage or other charges in converting the securities to cash.

Systematic Withdrawal Plan. The transfer agent will send to the shareholder regular monthly or quarterly payments of any permitted amount designated by the shareholder based upon the value of the shares held. The checks will be drawn from share redemptions and hence, may require the recognition of taxable gain or loss. Income dividends and capital gains distributions in connection with withdrawal plan accounts will be credited at net asset value as of the record date for each distribution. Continued withdrawals in excess of current income will eventually use up principal, particularly in a period of declining market prices. A shareholder may not have a withdrawal plan in effect at the same time he or she has authorized Bank Automated Investing or is otherwise making regular purchases of Fund shares. The shareholder, the transfer agent or the principal underwriter may terminate the withdrawal plan at any time without penalty.

Other Information. The Fund’s net asset value per share is normally rounded to two decimal places. In certain situations (such as a merger, share split or a purchase or sale of shares that represents a significant portion of a share class), the administrator may determine to extend the calculation of the net asset value per share to additional decimal places to ensure that neither the value of the Fund nor a shareholder’s shares is diluted materially as the result of a purchase or sale or other transaction.

SALES CHARGES

Dealer Commissions. The principal underwriter may, from time to time, at its own expense, provide additional incentives to investment dealers which employ registered representatives who sell Fund shares and/or shares of other funds distributed by the principal underwriter. In some instances, such additional incentives may be offered only to certain investment dealers whose representatives sell or are expected to sell significant amounts of shares. In addition, the principal underwriter may from time to time increase or decrease the sales commissions payable to investment dealers. The principal underwriter may allow, upon notice to all investment dealers with whom it has agreements, discounts up to the full sales charge during the periods specified in the notice. During periods when the discount includes the full sales charge, such investment dealers may be deemed to be underwriters as that term is defined in the Securities Act of 1933.

Purchases at Net Asset Value. Advisers Class, Class A and Class I shares may be sold at net asset value to current and retired Directors and Trustees of Eaton Vance funds and portfolios; to clients (including custodial, agency, advisory and trust accounts) and current and retired officers and employees of Eaton Vance, its affiliates and other investment advisers and sub-advisers of Eaton Vance sponsored funds; and to such persons’ spouses, parents, siblings and lineal descendants and their beneficial accounts. Such shares may also be issued at net asset value (1) in connection with the merger (or similar transaction) of an investment company (or series or class thereof) or personal holding company with the Fund (or class thereof), (2) to investors making an investment as part of a fixed fee program whereby an entity unaffiliated with the investment adviser provides investment services, such as management, brokerage and custody, (3) to investment advisors, financial planners or other intermediaries who place trades for their own accounts or the accounts of their clients and who charge a management, consulting or similar ongoing fee for their services; clients of such investment advisors, financial planners or other intermediaries who place trades for their own accounts if the accounts are linked to the master account of such investment advisor, financial planner or other intermediary on the books and records of the broker or agent; financial intermediaries who have entered into an agreement with the principal underwriter to offer Class A shares through a no-load network or platform; and to retirement and deferred compensation plans and trusts used to fund those plans, including, but not limited to, those defined in Section 401(a), 403(b) or 457 of the Code and “rabbi trusts”, (4) to officers and employees of the Fund’s custodian and transfer agent, and (5) in connection with the ReFlow liquidity program. Class A shares may also be sold at net asset value to registered representatives and employees of investment dealers. Sales

24

charges generally are waived because either (i) there is no sales effort involved in the sale of shares or (ii) the investor is paying a fee (other than the sales charge) to the investment dealer involved in the sale.

The CDSC applicable to Class B shares will be waived in connection with minimum required distributions from tax-sheltered retirement plans by applying the rate required to be withdrawn under the applicable rules and regulations of the Internal Revenue Service to the balance of Class B shares in your account. Any new or revised sales charge or CDSC waiver will be prospective only.

Waiver of Investment Minimums. In addition to waivers described in the prospectus, minimum investment amounts are waived for current and retired Directors and Trustees of Eaton Vance funds and portfolios, clients (including custodial, agency, advisory and trust accounts), current and retired officers and employees of Eaton Vance, its affiliates and other investment advisers and sub-advisers of Eaton Vance sponsored funds, and for such persons’ spouses, parents, siblings and lineal descendants and their beneficial accounts. The minimum initial investment amount is also waived for officers and employees of a Fund’s custodian and transfer agent. Investments in the Fund by ReFlow in connection with the ReFlow liquidity program are also not subject to the minimum investment amount.

Statement of Intention. If it is anticipated that $100,000 or more of Class A shares and shares of other funds exchangeable for Class A shares of another Eaton Vance fund will be purchased within a 13-month period, the Statement of Intention section of the account application should be completed so that shares may be obtained at the same reduced sales charge as though the total quantity were invested in one lump sum. Shares eligible for the right of accumulation (see below) as of the date of the Statement and purchased during the 13-month period will be included toward the completion of the Statement. If you make a Statement of Intention, the transfer agent is authorized to hold in escrow sufficient shares (5% of the dollar amount specified in the Statement) which can be redeemed to make up any difference in sales charge on the amount intended to be invested and the amount actually invested. A Statement of Intention does not obligate the shareholder to purchase or the Fund to sell the full amount indicated in the Statement.

If the amount actually purchased during the 13-month period is less than that indicated in the Statement, the shareholder will be requested to pay the difference between the sales charge applicable to the shares purchased and the sales charge paid under the Statement of Intention. If the payment is not received in 20 days, the appropriate number of escrowed shares will be redeemed in order to realize such difference. If the total purchases during the 13-month period are large enough to qualify for a lower sales charge than that applicable to the amount specified in the Statement, all transactions will be computed at the expiration date of the Statement to give effect to the lower sales charge. Any difference will be refunded to the shareholder in cash or applied to the purchase of additional shares, as specified by the shareholder. This refund will be made by the investment dealer and the principal underwriter. If at the time of the recomputation, the investment dealer for the account has changed, the adjustment will be made only on those shares purchased through the current investment dealer for the account.

Right of Accumulation. Under the right of accumulation, the applicable sales charge level is calculated by aggregating the dollar amount of the current purchase and the value (calculated at the maximum current offering price) of any 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 the shareholder. Shares of Eaton Vance Cash Management Fund and Eaton Vance Tax Free Reserves cannot be accumulated for purposes of this privilege. The sales charge on the shares being purchased will then be applied at the rate applicable to the aggregate. Share purchases eligible for the right of accumulation are described under "Sales Charges" in the prospectus. For any such discount to be made available at the time of purchase a purchaser or his or her investment dealer must provide the principal underwriter (in the case of a purchase made through an investment dealer) or the transfer agent (in the case of an investment made by mail) with sufficient information to permit verification that the purchase order qualifies for the accumulation privilege. Confirmation of the order is subject to such verification. The right of accumulation privilege may be amended or terminated at any time as to purchases occurring thereafter.

Conversion Feature. Class B shares held for eight years will automatically convert to Class A shares. For purposes of this conversion, all distributions paid on Class B shares which the shareholder elects to reinvest in Class B shares will be considered to be held in a separate sub-account. Upon the conversion of Class B shares not acquired through the reinvestment of distributions, a pro rata portion of the Class B shares held in the sub-account will also convert to Class A shares. This portion will be determined by the ratio that the Class B shares being converted bears to the total of Class B shares (excluding shares acquired through reinvestment) in the account. This conversion feature is subject to the continuing availability of a ruling from the Internal Revenue Service or an opinion of counsel that the conversion is not taxable for federal income tax purposes.

25

Exchange Privilege. In addition to exchanges into the same class of another Eaton Vance fund, Class B shares may be exchanged for shares of a money market fund sponsored by an investment dealer and approved by the principal underwriter (an “investment dealer fund”). The CDSC will not be charged to the shareholder when the shares are exchanged for shares of the investment dealer fund; however, the shareholder will receive no credit toward the completion of the CDSC period for the time that the shareholder holds the exchanged shares of the investment dealer fund. If a shareholder redeems the exchanged shares of the investment dealer fund and does not invest the proceeds into Class B shares of an Eaton Vance fund, the shareholder will be subject to any CDSC applicable at the time the shareholder received the exchanged shares of the investment dealer fund.

Tax-Deferred Retirement Plans. Advisers Class, Class A, Class C and Class I shares are available for purchase in connection with certain tax-deferred retirement plans. Detailed information concerning these plans, including certain exceptions to minimum investment requirements, and copies of the plans are available from the principal underwriter. This information should be read carefully and consulting with an attorney or tax adviser may be advisable. The information sets forth the service fee charged for retirement plans and describes the federal income tax consequences of establishing a plan. Participant accounting services (including trust fund reconciliation services) will be offered only through third party recordkeepers and not by the principal underwriter. Under all plans, dividends and distributions will be automatically reinvested in additional shares.

Distribution Plans

The Trust has in effect a compensation-type Distribution Plan ^pursuant to Rule 12b-1 under the 1940 Act for Advisers Class and Class A shares (the “ Advisers Class and Class A ^ Plan”) . The Advisers Class and Class A Plan is designed to (i) finance activities which are primarily intended to result in the distribution and sales of Advisers Class and Class A shares and to make payments in connection with the distribution of such shares and (ii) pay service fees for personal services and/ or the maintenance of shareholder accounts to the principal underwriter, investment dealers and other persons. The distribution and service fees payable under the Advisers Class and Class A Plan shall not exceed 0.25% of the average daily net assets attributable to Advisers Class and Class A shares for any fiscal year. Advisers Class and Class A distribution and service fees are paid quarterly in arrears. In the case of distribution and service fees from Advisers Class shares, the principal underwriter may pay a portion of such fees to financial intermediaries pursuant to shareholder servicing or similar agreements with such firms. For the distribution and service fees paid by Advisers Class and Class A shares, see Appendix A and Appendix B.

The Trust also has in effect compensation-type Distribution Plans (the “Class B and Class C Plans“) pursuant to Rule 12b-1 under the 1940 Act for the Fund’s Class B and Class C shares. ^Each Class pays the principal underwriter a distribution fee, accrued daily and paid monthly, at an annual rate not exceeding 0.40% and 0.60% on Class B and Class C shares, respectively, of its average daily net assets to finance the distribution of its shares. Such fees compensate the principal underwriter for the sales commissions paid by it to investment dealers on the sale of shares, for other distribution expenses (such as personnel, overhead, travel, printing and postage) and for interest expenses. The principal underwriter ^ shall be entitled to receive all CDSCs paid or payable with respect to Class B and Class C shares, provided that no such sales ^ charge which would cause the Class B and ^Class ^ C to exceed the ^ maximum applicable cap imposed hereon by ^ Rule 2830 of the ^ FINRA Rules shall be imposed .

The Trustees of the Trust believe that each Plan will be a significant factor in the expected growth of the Fund’s assets, and will result in increased investment flexibility and advantages which have benefitted and will continue to benefit the Fund and its shareholders. The Eaton Vance organization will profit by reason of the operation of the Class B and Class C Plan through an increase in Fund assets and if at any point in time the aggregate amounts received by the principal underwriter pursuant to the Plans and from CDSCs have exceeded the total expenses incurred in distributing Class B and Class C shares. ^For sales ^ commissions and ^ CDSCs , see Appendix C and Appendix D.

The Class B and Class C Plans also authorizes the payment of service fees to the principal underwriter, investment dealers and other persons in amounts not exceeding an annual rate of 0. 20% and 0. 25% for Class B and Class C, respectively, of its average daily net assets for personal services, and/or the maintenance of shareholder accounts . The Trustees have currently authorized payment of service fees on Class C shares equal to 0.15% annually . For Class B, this fee is paid ^ monthly in arrears based on the value of shares sold by such persons. For Class C, investment dealers currently receive (a) a service fee (except on exchange transactions and reinvestments) at the time of sale equal to 0.15% of the purchase price of Class C shares sold by such dealer, and (b) monthly service fees approximately equivalent to 1/12 of 0.15% of the value of Class C shares sold by such dealer. During the first year after a purchase of Class C shares, the principal underwriter will retain the service fee as reimbursement for the service fee payment made to investment dealers at the time of sale. For the service fees paid, see Appendix C and Appendix D.

26

The Plans continue in effect from year to year so long as such continuance is approved at least annually by the vote of both a majority of (i) the noninterested Trustees of the Trust who have no direct or indirect financial interest in the operation of the Plan or any agreements related to the Plan (the “Plan Trustees”) and (ii) all of the Trustees then in office. Each Plan may be terminated at any time by vote of a majority of the Plan Trustees or by a vote of a majority of the outstanding voting securities of the applicable Class. Each Plan requires quarterly Trustee review of a written report of the amount expended under the Plan and the purposes for which such expenditures were made. The Plans may not be amended to increase materially the payments described therein without approval of the shareholders of the affected Class and the Trustees. So long as a Plan is in effect, the selection and nomination of the noninterested Trustees shall be committed to the discretion of such Trustees. The current Plans were initially approved by the Trustees, including the Plan Trustees, on August 6, 2007. The Trustees of the Trust who are “interested” persons of the Trust have an indirect financial interest in the Plans because their employers (or affiliates thereof) receive distribution and/or service fees under the Plans or agreements related thereto.
