You may exchange shares of the fund for the same class of shares of other funds sold by the distributor. For investors who qualify as Clients of Eligible Financial Intermediaries and participate in Eligible Investment Programs made available through their financial intermediaries (such as investors in fee-based advisory or mutual fund “wrap” programs), an exchange may be made from Class A or Class C shares to Class I shares of the same fund under certain limited circumstances. Please refer to the section of this prospectus titled “Retirement and Institutional Investors – eligible investors” or contact your financial intermediary for more information.

An exchange between funds is considered a sale and generally results in a capital gain or loss for federal income tax purposes, unless you are investing through an IRA, 401(k) or other tax-advantaged account. An exchange of shares of one class directly for shares of another class of the same fund normally should not be taxable for federal income tax purposes. You should talk to your tax advisor before making an exchange.

The exchange privilege is not intended as a vehicle for short-term trading. The fund may suspend or terminate your exchange privilege if you engage in a pattern of excessive exchanges.

You may exchange shares at their net asset value next determined after receipt by your Service Agent or the transfer agent of your exchange request in good order.

•    If you bought shares through a Service Agent, contact your Service Agent to learn which funds your Service Agent makes available to you for exchanges

•    If you bought shares directly from the fund, contact the fund at 1-877-721-1926 to learn which funds are available to you for exchanges

•    Exchanges may be made only between accounts that have identical registrations

•    Not all funds offer all classes

•    Some funds are offered only in a limited number of states. Your Service Agent or the fund will provide information about the funds offered in your state

•    Remember that an exchange is normally a taxable transaction unless you are investing through an IRA, 401(k) or other tax-advantaged account

Always be sure to read the Prospectus of the fund into which you are exchanging shares.

•    In most instances, your shares will not be subject to an initial sales charge or a contingent deferred sales charge at the time of the exchange. You may be charged an initial or contingent deferred sales charge if the shares being exchanged were not subject to a sales charge, for example if you are exchanging shares you purchased in Western Asset Money Market Fund for Class A or Class C shares of certain Legg Mason funds

•    Your contingent deferred sales charge (if any) will continue to be measured from the date of your original purchase of shares subject to a contingent deferred sales charge, and you will be subject to the contingent deferred sales charge of the fund that you originally purchased

•    You will generally be required to meet the minimum investment requirement for the class of shares of the fund or share class into which your exchange is made (except in the case of systematic exchange plans)

•    Your exchange will also be subject to any other requirements of the fund or share class into which you are exchanging shares

•    The fund may suspend or terminate your exchange privilege if you engage in a pattern of excessive exchanges
