The Securities and Exchange Commission has not approved or disapproved these securities or determined whether this Prospectus is accurate or complete. Any statement to the contrary is a crime.

Investment objective

The fund seeks long-term capital growth.

Fees and expenses of the fund

The accompanying table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in funds sold by Legg Mason Investor Services, LLC (“LMIS”), the fund’s distributor. More information about these and other discounts is available from your financial intermediary, in this Prospectus on page 16 under the heading “Sales charges” and in the fund’s statement of additional information (“SAI”) on page 49 under the heading “Sales Charge Waivers and Reductions.”

The fund no longer offers Class B shares for purchase by new or existing investors. Class B shares will continue to be available for dividend reinvestment and incoming exchanges.

Class 1 shares of the fund are not available for purchases or incoming exchanges.

Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes:

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio turnover. The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 23% of the average value of its portfolio.

Principal investment strategies

The fund invests primarily in equity securities that, in the portfolio managers’ opinion, offer the potential for capital growth. The fund may invest in issuers of any size, allowing the portfolio managers flexibility to identify investment opportunities that are expected to help the fund achieve its investment objective.

The portfolio managers follow an intrinsic value discipline in selecting securities, which means that the portfolio managers seek to purchase securities trading at large discounts to their assessment of the companies’ estimated value. The portfolio managers determine intrinsic value by measuring the company’s value on such factors as the discounted value of its projected future free cash flows, the capability to earn returns on capital in excess of its cost of capital, private market values of similar companies and the costs to replicate the business. These and other factors may be more or less significant depending on the type of company. The portfolio managers may also consider qualitative factors in selecting stocks, including an assessment of the company’s products, competitive positioning, strategy, industry economics and dynamics, and regulatory frameworks, among others. Securities may be undervalued due to, among other things, uncertainty arising from the limited availability of accurate information, economic growth and changes, changes in competitive conditions, technological change, investor overreaction to negative news or events, and changes in governmental policy or geopolitical dynamics.

The fund may invest up to 25% of its net assets in foreign securities.

Certain risks

Risk is inherent in all investing. There is no assurance that the fund will meet its investment objective. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the fund.

Stock market and equity securities risk. The securities markets are volatile and the market prices of the fund’s securities may decline generally. Securities fluctuate in price based on changes in a company’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the fund fall, the value of your investment in the fund will decline. The recent financial crisis has caused a significant decline in the value and liquidity of many securities. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could also negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the United States calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time.

Issuer risk. The value of a stock can go up or down more than the market as a whole and can perform differently from the value of the market as a whole, often due to disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer or changes in government regulations affecting the issuer or the competitive environment. The fund may experience a substantial or complete loss on an individual stock. Historically, the prices of securities of small and medium capitalization companies have generally gone up or down more than those of large capitalization companies, although even large capitalization companies may fall out of favor with investors.

Liquidity risk. Some securities held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid securities may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.

Foreign investments risk. The fund’s investments in securities of foreign issuers involve greater risk than investments in securities of U.S. issuers. Foreign countries in which the fund may invest may have markets that are less liquid and more volatile than U.S. markets and may suffer from political or economic instability. In some foreign countries, less information is available about issuers and markets because of less rigorous accounting and regulatory standards than in the United States. Currency fluctuations could erase investment gains or add to investment losses.

Portfolio selection risk. The value of your investment may decrease if the portfolio managers’ judgment about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements is incorrect.

Value investing risk. The value approach to investing involves the risk that stocks may remain undervalued. Value stocks may underperform the overall equity market while the market concentrates on growth stocks.

Although the fund will not concentrate its investments in any one industry or industry group, it may, like many value funds, weight its investments toward certain industries, thus increasing its exposure to factors adversely affecting issuers within those industries.

Non-diversification risk. The fund is classified as “non-diversified,” which means it may invest a larger percentage of its assets in a small number of issuers than a diversified fund. To the extent the fund invests its assets in fewer issuers, the fund will be more susceptible to negative events affecting those issuers than a diversified fund.

Risk of increase in expenses. Your actual costs of investing in the fund may be higher than the expenses shown in “Annual fund operating expenses” for a variety of reasons. For example, expense ratios may be higher than those shown if a fee limitation is changed or terminated or if average net assets decrease. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile.

These risks are discussed in more detail later in this Prospectus or in the SAI.

More on the fund’s investment strategies, investments and risks

The fund seeks long-term capital growth.

The fund invests primarily in equity securities that, in the portfolio managers’ opinion, offer the potential for capital growth. The fund may invest in issuers of any size, allowing the portfolio managers flexibility to identify investment opportunities that are expected to help the fund achieve its investment objective.

The portfolio managers follow an intrinsic value discipline in selecting securities, which means that the portfolio managers seek to purchase securities trading at large discounts to their assessment of the companies’ estimated value. The portfolio managers determine intrinsic value by measuring the company’s value on such factors as the discounted value of its projected future free cash flows, the capability to earn returns on capital in excess of its cost of capital, private market values of similar companies and the costs to replicate the business. These and other factors may be more or less significant depending on the type of company. The portfolio managers may also consider qualitative factors in selecting stocks, including an assessment of the company’s products, competitive positioning, strategy, industry economics and dynamics, and regulatory frameworks, among others. Securities may be undervalued due to, among other things, uncertainty arising from the limited availability of accurate information, economic growth and changes, changes in competitive conditions, technological change, investor overreaction to negative news or events, and changes in governmental policy or geopolitical dynamics.

The fund may invest up to 25% of its net assets in foreign securities.

The fund’s investment objective and investment strategies may be changed without shareholder approval.

The fund is classified as “non-diversified,” which means it may invest a larger percentage of its assets in a small number of issuers than a diversified fund.

Cash management

The fund may hold cash pending investment, and may invest in money market instruments for cash management purposes. The amount of assets the fund may hold for cash management purposes will depend on market conditions and the need to meet expected redemption requests.

Equity investments

Equity securities include exchange-traded and over-the-counter (OTC) common and preferred stocks, warrants and rights, securities convertible into common stocks, and securities of other investment companies and of real estate investment trusts.

Derivatives and hedging techniques

Derivatives are financial instruments whose value depends upon, or is derived from, the value of an asset, such as one or more investments, indexes or currencies. The fund may engage in a variety of transactions using derivatives, such as futures and options on securities, securities indexes or currencies, options on these futures, forward currency contracts, and interest rate or currency swaps. Derivatives may be used by the fund for any of the following purposes:

A derivative contract will obligate or entitle the fund to deliver or receive an asset or cash payment based on the change in value of one or more investments, indexes or currencies. When the fund enters into derivatives transactions, it may be required to segregate assets or enter into offsetting positions, in accordance with applicable regulations. Such segregation is not a hedging technique and will not limit the fund’s exposure to loss. The fund will, therefore, have investment risk with respect to both the derivative itself and the assets that have been segregated to offset the fund’s derivative exposure. If such segregated assets

More on the fund’s investment strategies, investments and risks cont’d

represent a large portion of the fund’s portfolio, portfolio management may be affected as covered positions may have to be reduced if it becomes necessary for the fund to reduce the amount of segregated assets in order to meet redemptions or other obligations.

Should the fund invest in derivatives, the fund will, in determining compliance with any percentage limitation or requirement regarding the use or investment of fund assets, take into account the market value of the fund’s derivative positions that are intended to reduce or create exposure to the applicable category of investments.

Foreign investments

The fund may invest up to 25% of its net assets in the equity securities of foreign issuers, either directly or through depositary receipts.

Fund of funds investments

The fund may be an investment option for other Legg Mason-managed mutual funds that are managed as a “fund of funds.”

Defensive investing

The fund may depart from its principal investment strategies in response to adverse market, economic or political conditions by taking temporary defensive positions in any type of money market instruments, short-term debt securities or cash without regard to any percentage limitations. Although the manager has the ability to take defensive positions, it may choose not to do so for a variety of reasons, even during volatile market conditions.

Other investments

The fund may also use other strategies and invest in other securities that are described, along with their risks, in the SAI. However, the fund might not use all of the strategies and techniques or invest in all of the types of securities described in this Prospectus or in the SAI.

More on risks of investing in the fund

Stock market and equity securities risk. Securities fluctuate in price based on changes in a company’s financial condition and overall market and economic conditions. The value of a particular security may decline due to factors that affect a particular industry or industries, such as an increase in production costs, competitive conditions or labor shortages; or due to general market conditions, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.

Issuer risk. The value of a security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of a company’s securities may deteriorate because of a variety of factors, including disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer or changes in government regulations affecting the issuer or the competitive environment.

Large capitalization company risk. Large capitalization companies may fall out of favor with investors.

Small and medium capitalization company risk. The fund will be exposed to additional risks as a result of its investments in the securities of small and medium capitalization companies. Small and medium capitalization companies may fall out of favor with investors; may have limited product lines, operating histories, markets or financial resources; or may be dependent upon a limited management group. The prices of securities of small and medium capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by

changes in earnings results and investor expectations or poor economic or market conditions, including those experienced during a recession. Securities of small and medium capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

Liquidity risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the fund’s investments must be liquid at the time of investment, investments may become illiquid after purchase by the fund, particularly during periods of market turmoil. When the fund holds illiquid investments, the portfolio may be harder to value, especially in changing markets, and if the fund is forced to sell these investments to meet redemption requests or for other cash needs, the fund may suffer a loss. In addition, when there is illiquidity in the market for certain investments, the fund, due to limitations on illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

Foreign investments risk. The fund’s investments in securities of foreign issuers involve greater risk than investments in securities of U.S. issuers. Foreign countries in which the fund may invest may have markets that are less liquid and more volatile than markets in the United States, may suffer from political or economic instability and may experience negative government actions, such as currency controls or seizures of private businesses or property. In some foreign countries, less information is available about issuers and markets because of less rigorous accounting and regulatory standards than in the United States. Foreign withholdings may reduce the fund’s returns. Currency fluctuations could erase investment gains or add to investment losses. Because the value of a depositary receipt is dependent upon the market price of an underlying foreign security, depositary receipts are subject to most of the risks associated with investing in foreign securities directly.

Portfolio selection risk. The value of your investment may decrease if the portfolio managers’ judgment about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements is incorrect.

Value investing risk. The value approach to investing involves the risk that value stocks may remain undervalued. Value stocks as a group may be out of favor and underperform the overall equity market for a long period of time, while the market concentrates on growth stocks. Although the fund will not concentrate its investments in any one industry or industry group, it may, like many value funds, weight its investments toward certain industries, thus increasing its exposure to factors adversely affecting issuers within those industries.

Non-diversification risk. The fund is classified as “non-diversified,” which means it may invest a larger percentage of its assets in a small number of issuers than a diversified fund. To the extent the fund invests its assets in fewer issuers, the fund will be more susceptible to negative events affecting those issuers than a diversified fund.

Cash management and defensive investing risk. The value of the investments held by the fund for cash management or defensive investing purposes may be affected by changing interest rates and by changes in credit ratings of the investments. If the fund holds cash uninvested it will be subject to the credit risk of the depository institution holding the cash. If a significant amount of the fund’s assets are used for cash management or defensive investing purposes, it will be more difficult for the fund to achieve its investment objective.

Derivatives risk. Using derivatives, especially for non-hedging purposes, may involve greater risks to the fund than investing directly in securities, particularly as these instruments may be very complex and may not behave in the manner anticipated. Certain derivatives transactions may have a leveraging effect on the fund. Even a small investment in derivative contracts can have a significant impact on the fund’s stock market, interest rate or currency exposure. Therefore, using derivatives can disproportionately increase losses and reduce opportunities for gains when stock prices, currency rates or interest rates are changing. The fund may not fully benefit from or may lose money on derivatives if changes in their value do not correspond as anticipated to changes in the value of the fund’s holdings. Using derivatives may increase volatility, which is the characteristic of a security, an index or a market to fluctuate significantly in price

More on the fund’s investment strategies, investments and risks cont’d

within a short time period. Holdings of derivatives also can make the fund less liquid and harder to value, especially in declining markets.

Derivatives are subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.

Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation are not yet fully known and may not be for some time. New regulation of derivatives may make them more costly, may limit their availability, or may otherwise adversely affect their value or performance.

Risks associated with the use of derivatives are magnified to the extent that a large portion of the fund’s assets are committed to derivatives in general or are invested in just one or a few types of derivatives.

Fund of funds investments risk. From time to time, the fund may experience relatively large redemptions or investments due to rebalancings of a fund of funds’ portfolio. In the event of such redemptions or investments, the fund could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

Risk of increase in expenses. Your actual costs of investing in the fund may be higher than the expenses shown in “Annual fund operating expenses” for a variety of reasons. For example, expense ratios may be higher than those shown if a fee limitation is changed or terminated or if average net assets decrease. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile.

Recent market events risk. The equity and debt capital markets in the United States and internationally have experienced unprecedented volatility. This financial crisis has caused a significant decline in the value and liquidity of many securities. This environment could make identifying investment risks and opportunities especially difficult for the manager. These market conditions may continue or get worse. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support could also negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the United States calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time.

Please note that there are other factors that could adversely affect your investment and that could prevent the fund from achieving its investment objective. More information about risks appears in the SAI. Before investing, you should carefully consider the risks that you will assume.

Portfolio holdings

A description of the fund’s policies and procedures with respect to the disclosure of its portfolio holdings is available in the SAI. The fund posts its complete portfolio holdings at http://www.leggmason.com/individualinvestors/prospectuses (click on the name of the fund) on a quarterly basis. The fund intends to post its complete portfolio holdings 14 calendar days following the quarter-end. The fund intends to post partial information concerning the fund’s portfolio holdings (such as top 10 holdings or sector breakdowns, for example) on the Legg Mason funds’ website on a monthly basis. The fund intends to post this partial information 10 business days following each month-end. Such information will remain available until the next month’s or quarter’s holdings are posted.

Management fee

The fund pays a management fee at an annual rate that decreases as assets increase, as follows: 0.70% of assets up to and including $2 billion and 0.65% of assets over $2 billion.

For the fiscal year ended April 30, 2011, the fund paid LMCM an effective management fee of 0.70% of the fund’s average daily net assets for management services, after waivers and/or reimbursements.

A discussion regarding the basis for the Board of Trustees (the “Board”) approval of the fund’s management agreement is available in the fund’s Annual Report for the fiscal year ended April 30, 2011.

Expense limitation

The manager has agreed to waive fees and/or reimburse operating expenses (other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses) so that total annual operating expenses are not expected to exceed 1.30% for Class FI shares, 1.55% for Class R shares, 2.05% for Class R1 shares and 1.00% for Class I shares, subject to recapture as described below. In addition, total annual fund

operating expenses for Class 1 shares are expected to be at least 0.25% lower than total annual fund operating expenses for Class A shares. These arrangements are expected to continue until December 31, 2012, may be terminated prior to that date by agreement of the manager and the Board, and may be terminated at any time after that date by the manager. These arrangements, however, may be modified by the manager to decrease total annual operating expenses at any time. The manager is also permitted to recapture fees waived or expenses reimbursed to a class during the same fiscal year if the class’ total annual operating expenses have fallen to a level below the limit described above. In no case will the manager recapture any amount that would result, on any particular business day of the fund, in the class’ total annual operating expenses exceeding the applicable limits described above or any other lower limit then in effect.

Distribution

LMIS, a wholly-owned broker/dealer subsidiary of Legg Mason, serves as the fund’s sole and exclusive distributor.

The fund has adopted a Rule 12b-1 shareholder services and distribution plan. Under the plan, the fund pays distribution and/or service fees based on annualized percentages of average daily net assets, of up to 0.25% for Class A shares; up to 1.00% for Class B shares; up to 1.00% for Class C shares; up to 0.25% for Class FI shares; up to 0.50% for Class R shares; and up to 1.00% for Class R1 shares. These fees are an ongoing expense and, over time, will increase the cost of your investment and may cost you more than other types of sales charges. Class I shares and Class 1 shares are not subject to distribution and/or service fees under the plan.

In addition, the distributor, the manager and/or their affiliates make payments for distribution, shareholder servicing, marketing and promotional activities and related expenses out of their profits and other available sources, including profits from their relationships with the fund. These payments are not reflected as additional expenses in the fee table contained in this Prospectus. The recipients of these payments may include the fund’s distributor and affiliates of the manager, as well as non-affiliated broker/dealers, insurance companies, financial institutions and other financial intermediaries through which investors may purchase shares of the fund, including your financial intermediary. The total amount of these payments is substantial, may be substantial to any given recipient and may exceed the costs and expenses incurred by the recipient for any fund-related marketing or shareholder servicing activities. The payments described in this paragraph are often referred to as “revenue sharing payments.” Revenue sharing arrangements are separately negotiated.

Revenue sharing payments create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the fund to you. Contact your financial intermediary for details about revenue sharing payments it receives or may receive. Revenue sharing payments, as well as payments under the shareholder services and distribution plan (where applicable), also benefit the manager, the distributor and their affiliates to the extent the payments result in more assets being invested in the fund on which fees are being charged.

Choosing a class of shares to buy

Individual investors can generally invest in Class A and Class C shares. Individual investors who held Class I shares prior to November 20, 2006 are permitted to make additional investments in Class I shares. Effective July 27, 2007, the fund’s Class 1 shares were closed to all purchases and incoming exchanges. Investors owning Class 1 shares on that date may continue to maintain their then-current Class 1 shares, but are no longer permitted to add to their Class 1 share positions (excluding reinvestment of dividends and distributions). Retirement Plan and Institutional Investors and Clients of Eligible Financial Intermediaries should refer to “Retirement and Institutional Investors — eligible investors” below for a description of the classes available to them.

Each class has different sales charges and expenses, allowing you to choose a class that may be appropriate for you.

When choosing which class of shares to buy, you should consider:

If you plan to invest a large amount and/or your investment horizon is five years or more, Class C shares might not be as advantageous as Class A shares. The annual distribution and/or service fees on Class C shares may cost you more over the longer term than the front-end sales charge you would have paid for larger purchases of Class A shares.

The fund no longer offers Class B shares for purchase by new or existing investors. Individual investors who owned Class B shares on June 30, 2011 may continue to hold those shares, but they may not add to their Class B share positions except through dividend reinvestment. Class B shares are also available for incoming exchanges.

Each class of shares except Class 1 shares is authorized to pay fees for recordkeeping services to Service Agents. As a result, operating expenses of classes that incur new or additional recordkeeping fees may increase over time.

You may buy shares:

Your Service Agent may provide shareholder services that differ from the services provided by other Service Agents. Services provided by your Service Agent may vary by class. You should ask your Service Agent to explain the shareholder services it provides for each class and the compensation it receives in connection with each class. Remember that your Service Agent may receive different compensation depending on the share class in which you invest.

Your Service Agent may not offer all classes of shares. You should contact your Service Agent for further information.

More information about the fund’s classes of shares is available through the Legg Mason funds’ website. You’ll find detailed information about sales charges and ways you can qualify for reduced or waived sales charges, including:

Comparing the fund’s classes

The following table compares key features of the fund’s classes. You should review the fee table and example at the front of this Prospectus carefully before choosing your share class. Your Service Agent can help you choose a class that may be appropriate for you. Please contact your Service Agent regarding the availability of Class FI, Class R or Class R1 shares. You may be required to provide appropriate documentation confirming your eligibility to invest in Class FI, Class R or Class R1 shares. Your Service Agent may receive different compensation depending upon which class you choose.

Sales charges

Class A shares

You buy Class A shares at the offering price, which is the net asset value plus a sales charge. You pay a lower rate as the size of your investment increases to certain levels called breakpoints. You do not pay a sales charge on the fund’s distributions or dividends that you reinvest in additional Class A shares.

The table below shows the rate of sales charge you pay, depending on the amount you purchase. It also shows the amount of broker/dealer compensation that will be paid out of the sales charge if you buy shares from a Service Agent. For Class A shares sold by the distributor, the distributor will receive the sales charge imposed on purchases of Class A shares (or any contingent deferred sales charge paid on redemptions) and will retain the full amount of such sales charge. Service Agents will receive a distribution and/or service fee payable on Class A shares at an annual rate of up to 0.25% of the average daily net assets represented by the Class A shares serviced by them.

Investments of $1,000,000 or more

You do not pay an initial sales charge when you buy $1,000,000 or more of Class A shares. However, if you redeem these Class A shares within one year of purchase, you will pay a contingent deferred sales charge of 1.00%.

Qualifying for a reduced Class A sales charge

There are several ways you can combine multiple purchases of Class A shares of funds sold by the distributor to take advantage of the breakpoints in the sales charge schedule. In order to take advantage of reductions in sales charges that may be available to you when you purchase fund shares, you must inform your Service Agent or the fund if you are eligible for a letter of intent or a right of accumulation and if you own shares of other funds that are eligible to be aggregated with your purchases. Certain records, such as account statements, may be necessary in order to verify your eligibility for a reduced sales charge.

with the dollar amount of your next purchase of Class A shares for purposes of calculating the initial sales charges.

If you hold fund shares in accounts at two or more Service Agents, please contact your Service Agents to determine which shares may be combined.

Shares of money market funds sold by the distributor acquired by exchange from other funds offered with a sales charge may be combined. Please contact your Service Agent for additional information.

Certain trustees and fiduciaries may be entitled to combine accounts in determining their sales charge.

are eligible for inclusion under the letter of intent, based on the public offering price at the time of the purchase and any capital appreciation on those shares. In addition, you can include toward your asset goal amount the current value of any eligible holdings.

If you hold shares of funds sold by the distributor in accounts at two or more Service Agents, please contact your Service Agents to determine which shares may be credited toward your letter of intent asset goal.

Shares of money market funds sold by the distributor acquired by exchange from other funds offered with a sales charge may be credited toward your letter of intent asset goal. Please contact your Service Agent for additional information.

If you do not meet your asset goal amount, shares in the amount of any sales charges due, based on the amount of your actual purchases, will be redeemed from your account.

Waivers for certain Class A investors

Class A initial sales charges are waived for certain types of investors, including:

If you qualify for a waiver of the Class A initial sales charge, you must notify your Service Agent or the fund at 1-877-721-1926 at the time of purchase and provide sufficient information at the time of purchase to permit verification that the purchase qualifies for the initial sales charge waiver.

If you want to learn about additional waivers of Class A initial sales charges, contact your Service Agent, consult the SAI or visit the Legg Mason funds’ website, http://www.leggmason.com/individualinvestors/products, and click on the name of the fund in the dropdown menu.

Class B shares

The fund no longer offers Class B shares for purchase by new or existing investors. If you owned Class B shares on June 30, 2011, you may continue to hold those shares, but you may not add to your Class B share position except through dividend reinvestment. Class B shares are also available for incoming exchanges. Class B shares are issued at net asset value with no initial sales charge. If you redeem your Class B shares within five years of your purchase payment, you will pay a contingent deferred sales charge. The contingent deferred sales charge decreases as the number of years since your purchase payment increases.

LMIS will retain the contingent deferred sales charges. The fund pays annual distribution and/or service fees of up to 1.00% of the average daily net assets of Class B shares. Service Agents receive an annual distribution and/or service fee of up to 0.25% of the average daily net assets represented by the Class B shares serviced by them.

Sales charges cont’d

Class B conversion

After approximately 8 years, Class B shares automatically convert into Class A shares. This helps you because Class A shares have lower annual expenses. Your Class B shares will convert to Class A shares as follows:

Class C shares

You buy Class C shares at net asset value with no initial sales charge. However, if you redeem your Class C shares within one year of purchase, you will pay a contingent deferred sales charge of 1.00%.

LMIS generally will pay Service Agents selling Class C shares a commission of up to 1.00% of the purchase price of the Class C shares they sell. LMIS will retain the contingent deferred sales charges and an annual distribution and/or service fee of up to 1.00% of the average daily net assets represented by the Class C shares serviced by these Service Agents until the thirteenth month after purchase. Starting in the thirteenth month after purchase, these Service Agents will receive an annual distribution and/or service fee of up to 1.00% of the average daily net assets represented by the Class C shares serviced by them.

Class FI, Class R and Class R1 shares

You buy Class FI, Class R and Class R1 shares at net asset value with no initial sales charge and no contingent deferred sales charge when redeemed.

Service Agents receive an annual distribution and/or service fee of up to 0.25% of the average daily net assets represented by Class FI shares serviced by them, up to 0.50% of the average daily net assets represented by Class R shares serviced by them and up to 1.00% of the average daily net assets represented by Class R1 shares serviced by them.

Class I shares

You buy Class I shares at net asset value with no initial sales charge and no contingent deferred sales charge when redeemed. Class I shares are not subject to any distribution and/or service fees.

Class 1 shares

The fund no longer offers Class 1 shares for purchase by new or existing investors or for incoming exchanges. If you owned Class 1 shares on July 26, 2007, you may continue to hold those shares, but you may not add to your Class 1 share position except through dividend reinvestment.

More about contingent deferred sales charges

The contingent deferred sales charge is based on the net asset value at the time of purchase or redemption, whichever is less, and therefore you do not pay a sales charge on amounts representing appreciation or depreciation.

In addition, you do not pay a contingent deferred sales charge:

Each time you place a request to redeem shares, the fund will first redeem any shares in your account that are not subject to a contingent deferred sales charge and then redeem the shares in your account that have been held the longest.

If you redeem shares of a fund sold by the distributor and pay a contingent deferred sales charge, you may, under certain circumstances, reinvest all or part of the redemption proceeds within 60 days and receive pro rata credit for any contingent deferred sales charge imposed on the prior redemption. Please contact your Service Agent for additional information.

The distributor receives contingent deferred sales charges as partial compensation for its expenses in selling shares, including the payment of compensation to your Service Agent.

Contingent deferred sales charge waivers

The contingent deferred sales charge for each share class will generally be waived:

If you want to learn more about additional waivers of contingent deferred sales charges, contact your Service Agent, consult the SAI or visit the Legg Mason funds’ website, http://www.leggmason.com/individualinvestors/products, and click on the name of the fund in the dropdown menu.

Retirement and Institutional Investors —

eligible investors

Retirement Plans

“Retirement Plans” include 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit-sharing plans, non-qualified deferred compensation plans and other similar employer-sponsored retirement plans. Retirement Plans do not include individual retirement vehicles, such as traditional and Roth individual retirement accounts, Coverdell education savings accounts, individual 403(b)(7) custodial accounts, Keogh plans, SEPs, SARSEPs, SIMPLE IRAs or similar accounts.

Retirement Plans with omnibus accounts held on the books of the fund can generally invest in Class C, Class FI, Class R, Class R1 and Class I shares.

Although Retirement Plans with omnibus accounts held on the books of the fund are not subject to minimum initial investment requirements for any of these share classes, certain investment minimums may be imposed by a financial intermediary. The distributor may impose certain additional requirements. Please contact your Service Agent for more information.

Class A shares are no longer offered through Service Agents for Retirement Plans with omnibus accounts held on the books of the fund, with limited exceptions. Class A shares will cease to be available to new Retirement Plan investors through a Service Agent if the Service Agent makes Class FI shares available. Class C shares will cease to be available to new Retirement Plan investors through a Service Agent if the Service Agent makes Class R1 shares available. Please see below for additional information.

Other Retirement Plans

“Other Retirement Plans” include Retirement Plans investing through brokerage accounts and also include certain Retirement Plans with direct relationships to the fund that are neither Institutional Investors nor investing through omnibus accounts. Other Retirement Plans and individual retirement vehicles, such as IRAs, are treated like individual investors for purposes of determining sales charges and any applicable sales charge reductions or waivers.

Other Retirement Plan investors can generally invest in Class A and Class C shares. Individual retirement vehicles may also choose between these share classes.

Clients of Eligible Financial Intermediaries

“Clients of Eligible Financial Intermediaries” are investors who invest in the fund through financial intermediaries that (i) charge such investors an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the distributor to offer Class I shares through a no-load network or platform (“Eligible Investment Programs”). Such investors may include pension and profit sharing plans, other employee benefit trusts, endowments, foundations and corporations. Eligible Investment Programs may also include college savings vehicles such as Section 529 plans. The financial intermediary may impose separate investment minimums.

Clients of Eligible Financial Intermediaries may generally invest in Class A, Class FI or Class I shares.

Institutional Investors

“Institutional Investors” may include corporations, banks, trust companies, insurance companies, investment companies, foundations, endowments, defined benefit plans and other similar entities. The distributor or the financial intermediary may impose additional eligibility requirements or criteria to determine if an investor, including the types of investors listed above, qualifies as an Institutional Investor.

Institutional Investors may invest in Class I shares if they meet the $1,000,000 minimum initial investment requirement. Institutional Investors may also invest in Class A and Class C shares, which have different investment minimums, fees and expenses.

Class A shares — Retirement Plans

Class A shares are no longer offered through Service Agents to Retirement Plans with omnibus accounts held on the books of the fund. Certain existing programs for current and prospective Retirement Plan investors sponsored by financial intermediaries also remain eligible to purchase Class A shares. Under these programs, the initial sales charge and contingent deferred sales charge for Class A shares are waived where:

LMIS does not pay Service Agents selling Class A shares to Retirement Plans with a direct omnibus relationship with the fund a commission on the purchase price of Class A shares sold by them. However, for certain Retirement Plans that are permitted to purchase shares at net asset value, LMIS may pay Service Agents commissions of up to 1.00% of the purchase price of the Class A shares that are purchased with regular ongoing plan contributions. Please contact your Service Agent for more information.

Class B shares

The fund no longer offers Class B shares for purchase or by new or existing investors. Institutional Investors and certain Retirement Plans that owned Class B shares on June 30, 2011, may continue to hold those shares, but they may not add to their Class B share positions except through dividend reinvestment. Class B shares are also available for incoming exchanges.

Class C shares — Retirement Plans

Retirement Plans with omnibus accounts held on the books of the fund may buy Class C shares at net asset value without paying a contingent deferred sales charge. LMIS does not pay Service Agents selling Class C shares to Retirement Plans with omnibus accounts held on the books of the fund a commission on the purchase price of Class C shares sold by them. Instead, immediately after purchase, LMIS may pay these Service Agents an annual distribution and/or service fee of up to 1.00% of the average daily net assets represented by the Class C shares serviced by them.

Certain Retirement Plan programs with exchange features in effect prior to November 20, 2006, as approved by LMIS, will remain eligible for exchange from Class C shares to Class A shares in accordance with the program terms. Please see the SAI for more details.

Class FI shares

Class FI shares are offered only to investors who invest in the fund through certain financial intermediaries and Retirement Plan programs.

Class R shares

Class R shares are offered only to Retirement Plans with accounts held on the books of the fund (either at the plan level or at the level of the financial intermediary).

Class R1 shares

Class R1 shares are offered only to Retirement Plans with accounts held on the books of the fund (either at the plan level or at the level of the financial intermediary).

Class I shares

Class I shares are offered only to Institutional Investors who meet the $1,000,000 minimum initial investment requirement, Clients of Eligible Financial Intermediaries and other investors authorized by LMIS.

Certain waivers of these requirements for individuals associated with the fund, Legg Mason or its affiliates are discussed in the SAI.

Other considerations

Plan sponsors, plan fiduciaries and other financial intermediaries may choose to impose qualification requirements that differ from the fund’s share class eligibility standards. In certain cases this could result in the selection of a share class with higher distribution and/or service fees than otherwise would have been charged. The fund is not responsible for, and has no control over, the decision of any plan sponsor, plan fiduciary or financial intermediary to impose such differing requirements. Please consult with your plan sponsor, plan fiduciary or financial intermediary for more information about available share classes.

Your Service Agent may not offer all share classes. Please contact your Service Agent for additional details.

Exchanging shares

Redeeming shares

Other things to know about transactions

When you buy, exchange or redeem shares, your request must be in good order. This means you have provided the following information, without which your request may not be processed:

The fund generally will not permit non-resident aliens with non-U.S. addresses to establish accounts. U.S. citizens with APO/FPO addresses or addresses in the United States (including its territories) and resident aliens with U.S. addresses are permitted to establish accounts with the fund. Subject to the requirements of local law, U.S. citizens residing in foreign countries are permitted to establish accounts with the fund.

In certain circumstances, such as during periods of market volatility, severe weather and emergencies, shareholders may experience difficulties placing exchange or redemption orders by telephone. In that case, shareholders should consider using the fund’s other exchange and redemption procedures described under “Exchanging shares” and “Redeeming shares.”

The transfer agent or the fund will employ reasonable procedures to confirm that any telephone exchange or redemption request is genuine, which may include recording calls, asking the caller to provide certain personal identification information, sending you a written confirmation or requiring other confirmation procedures from time to time. If these procedures are followed, neither the fund nor its agents will bear any liability for these transactions.

The fund has the right to:

Signature guarantees

To be in good order, your redemption request must include a signature guarantee if you:

You can obtain a signature guarantee from most banks, dealers, brokers, credit unions and federal savings and loan institutions, but not from a notary public.

Anti-money laundering

Federal anti-money laundering regulations require all financial institutions to obtain, verify and record information that identifies each person who opens an account. When you sign your account application, you may be asked to provide additional information in order for the fund to verify your identity in accordance with these regulations. Accounts may be restricted and/or closed, and the monies withheld, pending verification of this information or as otherwise required under these and other federal regulations.

Small account fees/Mandatory redemptions

Small accounts may be subject to a small account fee or to mandatory redemption, as described below, depending on whether the account is held directly with the fund or through a Service Agent.

Direct accounts

Direct accounts generally include accounts held in the name of the individual investor on the fund’s books and records. To offset the relatively higher impact on fund expenses of servicing smaller direct accounts, if your shares are held in a direct account and the value of your account is below $1,000 (if applicable, $250 for retirement plans that are not employer-sponsored) for any reason (including declines in net asset value), the fund may charge you a fee of $3.75 per account that is determined and assessed quarterly on the last business day of the quarter (with an annual maximum of $15.00 per account). The small account fee will be charged effective September 30, 2011 (or as soon as possible thereafter in the fund’s discretion) by redeeming shares in your account. If the value of your account is $3.75 or less, the amount in the account may be exhausted to pay the small account fee. The small account fee will not be assessed on systematic investment plans until the end of the first quarter after the account has been established for 15 months. The small account fee, including a share redemption, also may result in tax consequences to you (see “Taxes” for more information).

The small account fee will not be charged on, if applicable: (i) Retirement Plans (but will be charged on other plans that are not employer-sponsored such as traditional and Roth individual retirement accounts, Coverdell education savings accounts, individual 403(b)(7) custodial accounts, Keogh plans, SEPs, SARSEPs, SIMPLE IRAs or similar accounts); (ii) Legg Mason funds that have been closed to subsequent purchases for all classes; (iii) accounts that do not have a valid address as evidenced by mail being returned to the fund or its agents; and (iv) Class FI, Class R, Class R1, Class I or Class IS shares.

If your share class is no longer offered, you may not be able to bring your account up to the minimum investment amount (although you may exchange into existing accounts at other Legg Mason funds in which you hold the same share class, to the extent otherwise permitted by those funds and subject to any applicable sales charges).

Some shareholders who hold accounts in Classes A and B of the same fund may have those accounts aggregated for the purposes of these calculations. Please contact the fund or your Service Agent for more information.

Non-direct accounts

“Non-direct accounts” include omnibus accounts and accounts jointly maintained by the Service Agent and the fund. Such accounts are not subject to the small account fee that may be charged to direct accounts.

The fund reserves the right to ask you to bring your non-direct account up to a minimum investment amount determined by your Service Agent if the aggregate value of the fund shares in your account is less than $500 for any reason (including solely due to declines in net asset value and/or failure to invest at least $500 within a reasonable period). You will be notified in writing and will have 60 days to make an additional investment to bring your account value up to the required level. If you choose not to do so within this 60-day period, the fund may close your account and send you the redemption proceeds. If your share class is no longer offered, you may not be able to bring your account up to the minimum investment amount. Some shareholders who hold accounts in multiple classes of the same fund may have those accounts aggregated for the purposes of these calculations. If your account is closed, you will not be eligible to have your account reinstated without imposition of any sales charges that may apply to your new purchase. Please contact your Service Agent for more information. Any redemption of fund shares may result in tax consequences to you (see “Taxes” for more information).

Other things to know about transactions cont’d

All accounts

The fund may, with prior notice, change the minimum size of accounts subject to mandatory redemption, which may vary by class, implement fees for small non-direct accounts or change the amount of the fee for small direct accounts.

Subject to applicable law, the fund may, with prior notice, adopt other policies from time to time requiring mandatory redemption of shares in certain circumstances.

For more information, please contact your Service Agent or the fund or consult the SAI.

Frequent trading of fund shares

Frequent purchases and redemptions of fund shares may interfere with the efficient management of the fund, increase fund transaction costs, and have a negative effect on the fund’s long-term shareholders. For example, in order to handle large flows of cash into and out of the fund, the portfolio managers may need to allocate more assets to cash or other short-term investments or sell securities, rather than maintaining full investment in securities selected to achieve the fund’s investment objective. Frequent trading may cause the fund to sell securities at less favorable prices. Transaction costs, such as brokerage commissions and market spreads, can detract from the fund’s performance. In addition, the return received by long-term shareholders may be reduced when trades by other shareholders are made in an effort to take advantage of certain pricing discrepancies, when, for example, it is believed that the fund’s share price, which is determined at the close of the NYSE on each trading day, does not accurately reflect the value of the fund’s investments. Funds investing in foreign securities have been particularly susceptible to this form of arbitrage, but other funds could also be affected.

Because of the potential harm to funds sold by the fund’s distributor and their long-term shareholders, the Board has approved policies and procedures that are intended to detect and discourage excessive trading and market timing abuses through the use of various surveillance techniques. Under these policies and procedures, the fund may limit additional exchanges or purchases of fund shares by shareholders who are believed by the manager to be engaged in these abusive trading activities in the fund or in other funds sold by the distributor. In the event that an exchange or purchase request is rejected, the shareholder may nonetheless redeem its shares. The intent of the policies and procedures is not to inhibit legitimate strategies, such as asset allocation, dollar cost averaging, or similar activities that may nonetheless result in frequent trading of fund shares.

Under the fund’s policies and procedures, the fund reserves the right to restrict or reject purchases of shares (including exchanges) without prior notice whenever a pattern of excessive trading by a shareholder is detected in funds sold by the distributor. A committee established by the manager administers the policy. The policy provides that the committee may take action, which may include using its best efforts to restrict a shareholder’s trading privileges in funds sold by the distributor, if that shareholder has engaged in one or more “Round Trips” across all funds sold by the distributor. However, the committee has the discretion to determine that action is not necessary if it is determined that the pattern of trading is not abusive or harmful. In making such a determination, the committee will consider, among other things, the nature of the shareholder’s account, the reason for the frequent trading, the amount of trading and the particular funds in which the trading has occurred. Additionally, the committee has the discretion to make inquiries or to take any action against a shareholder whose trading appears inconsistent with the frequent trading policy, regardless of the number of Round Trips. Examples of the types of actions the committee may take include heightened surveillance of a shareholder account, providing a written warning letter to an account holder, restricting the shareholder from purchasing additional shares in the fund altogether or imposing other restrictions (such as requiring purchase orders to be submitted by mail) that would deter the shareholder from trading frequently in the fund. The committee will generally follow a system of progressive deterrence, although it is not required to do so.

A “Round Trip” is defined as a purchase (including subscriptions and exchanges) into a fund sold by the distributor followed by a sale (including redemptions and exchanges) of the same or a similar number of shares out of that fund within 30 days of such purchase. Purchases and sales of the fund’s shares pursuant

to an automatic investment plan or similar program for periodic transactions are not considered in determining Round Trips. These policies and procedures do not apply to money market funds sold by the distributor.

The policies apply to any account, whether a direct account or accounts with financial intermediaries such as investment advisers, broker/dealers or retirement plan administrators, commonly called omnibus accounts, where the intermediary holds fund shares for a number of its customers in one account. The fund’s ability to monitor trading in omnibus accounts may, however, be severely limited due to the lack of access to an individual investor’s trading activity when orders are placed through these types of accounts. There may also be operational and technological limitations on the ability of the fund’s service providers to identify or terminate frequent trading activity within the various types of omnibus accounts. The distributor has entered into agreements with intermediaries requiring the intermediaries to, among other things, help identify frequent trading activity and prohibit further purchases or exchanges by a shareholder identified as having engaged in frequent trading.

The fund has also adopted policies and procedures to prevent the selective release of information about the fund’s holdings, as such information may be used for market-timing and similar abusive practices.

The policies provide for ongoing assessment of the effectiveness of current policies and surveillance tools, and the Board reserves the right to modify these or adopt additional policies and restrictions in the future. Shareholders should be aware, however, that any surveillance techniques currently employed by the fund or other techniques that may be adopted in the future may not be effective, particularly where the trading takes place through certain types of omnibus accounts. Furthermore, the fund may not apply its policies consistently or uniformly, resulting in the risk that some shareholders may be able to engage in frequent trading while others will bear the costs and effects of that trading.

Although the fund will attempt to monitor shareholder transactions for certain patterns of frequent trading activity, there can be no assurance that all such trading activity can be identified, prevented or terminated. Monitoring of shareholder transactions may only occur for shareholder transactions that exceed a certain transaction amount threshold, which may change from time to time. The fund reserves the right to refuse any client or reject any purchase order for shares (including exchanges) for any reason.

Share certificates

The fund does not issue share certificates. If you currently hold share certificates of the fund, the certificates will continue to be honored. If you would like to return your share certificates to the fund and hold your shares in uncertificated form, please contact your Service Agent or the fund.

Record ownership

If you hold shares through a Service Agent, your Service Agent may establish and maintain your account and be the shareholder of record. In the event that the fund holds a shareholder meeting, your Service Agent, as record holder, will vote your shares in accordance with your instructions. If you do not give your Service Agent voting instructions, your Service Agent, under certain circumstances, may nonetheless be entitled to vote your shares.

Dividends, distributions and taxes

Dividends and distributions

The fund generally pays dividends and makes capital gain distributions, if any, typically once or twice a year. The fund may pay additional distributions and dividends at other times if necessary for the fund to avoid a federal tax. The fund expects distributions to be primarily from capital gains. Unless otherwise directed, dividends and capital gain distributions are reinvested in additional fund shares of the same class you hold. You do not pay a sales charge on reinvested distributions or dividends. Alternatively, you can instruct your Service Agent or the fund to have your distributions and/or dividends paid in cash. You can change your choice at any time to be effective as of the next distribution or dividend.

If you own Class A or Class C shares and hold your shares directly with the fund, you may instruct the fund to have your distributions and/or dividends invested in Class A or Class C shares, respectively, of another fund sold by the distributor, subject to the following conditions:

To change your election to reinvest your dividends and distributions in shares of another fund, you must notify the fund at least three days before the next distribution is to be paid.

Please contact your Service Agent or the fund to discuss what options are available to you for receiving your dividends and distributions.

Taxes

The following discussion is very general and does not address investors subject to special rules, such as investors who hold shares in the fund through an IRA, 401(k) or other tax-advantaged account. Because each shareholder’s circumstances are different and special tax rules may apply, you should consult your tax adviser about your investment in the fund.

In general, unless your shares are held in a qualified retirement plan, IRA or other tax deferred arrangement, redeeming shares, exchanging shares and receiving dividends and distributions (whether in cash or additional shares) are all taxable events. An exchange between classes of shares of the same fund normally is not taxable for federal income tax purposes.

The following table summarizes the tax status to you of certain transactions related to the fund.

Distributions attributable to short-term capital gains are treated as dividends, taxable as ordinary income. Taxable dividends and long-term capital gain distributions are taxable whether received in cash or reinvested in fund shares. Although dividends (including dividends from short-term capital gains) are generally taxable as ordinary income, individual shareholders who satisfy certain holding period and other requirements are taxed on such dividends at long-term capital gain rates to the extent the dividends are attributable to “qualified dividend income” received by the fund if the fund satisfies the holding period and other requirements as well. “Qualified dividend income” generally consists of dividends received from U.S. corporations (other than certain dividends from real estate investment trusts) and certain foreign corporations. Long-term capital gain distributions are taxable to you as long-term capital gain regardless of how long you have owned your shares. You may want to avoid buying shares when the fund is about to declare a long-term capital gain distribution or a dividend because it will be taxable to you even though it may actually be a return of a portion of your investment.

A 3.8 percent Medicare contribution tax will be imposed on net investment income, including interest, dividends, and capital gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married filing jointly), and of estates and trusts.

The Internal Revenue Code will impose a U.S. withholding tax of 30% on payments (including gross proceeds) that are attributable to certain U.S. investments and made to non-U.S. persons, including non-U.S. investment funds. The fund will withhold at this rate on certain of its distributions and redemptions unless non-U.S. shareholders, including non-U.S. financial institutions, comply with certain reporting requirements to the Internal Revenue Service in respect of direct and indirect U.S. owners effective beginning with payments made after December 31, 2012. Non-U.S. shareholders should consult their own tax advisers regarding the possible implications of these requirements on their investments in the fund.

A dividend declared by the fund in October, November or December and paid during January of the following year will, in certain circumstances, be treated as paid in December for tax purposes.

After the end of each year, your Service Agent or the fund will provide you with information about the distributions and dividends you received and any redemptions of shares during the previous year. If you do not provide the fund with your correct taxpayer identification number and any required certifications, you may be subject to back-up withholding on your distributions, dividends and redemption proceeds. Because each shareholder’s circumstances are different and special tax rules may apply, you should consult your tax adviser about your investment in the fund.

The above discussion is applicable to shareholders who are U.S. persons. If you are a non-U.S. person, please consult your own tax adviser with respect to the U.S. tax consequences to you of an investment in the fund.

Share price

You may buy, exchange or redeem shares at their net asset value next determined after receipt of your request in good order, adjusted for any applicable sales charge. The fund’s net asset value per share is the value of its assets minus its liabilities divided by the number of shares outstanding. Net asset value is calculated separately for each class of shares.

The fund calculates its net asset value every day the NYSE is open. The fund generally values its securities and other assets and calculates its net asset value as of the close of regular trading on the NYSE, normally at 4:00 p.m. (Eastern time). If the NYSE closes at another time, the fund will calculate its net asset value as of the actual closing time. The NYSE is closed on certain holidays listed in the SAI.

In order to buy, redeem or exchange shares at a certain day’s price, you must place your order with your Service Agent or the transfer agent before the NYSE closes on that day. If the NYSE closes early on that day, you must place your order prior to the actual closing time. It is the responsibility of the Service Agent to transmit all orders to buy, exchange or redeem shares to the transfer agent on a timely basis.

Valuation of the fund’s securities and other assets is performed in accordance with procedures approved by the Board. These procedures delegate most valuation functions to LMPFA, which, in turn, uses independent third party pricing services approved by the fund’s Board. Under the procedures, assets are valued as follows:

Many factors may influence the price at which the fund could sell any particular portfolio investment. The sales price may well differ — higher or lower — from the fund’s last valuation, and such differences could be significant, particularly for securities that trade in relatively thin markets and/or markets that experience extreme volatility. Moreover, valuing securities using fair value methodologies involves greater reliance on judgment than valuing securities based on market quotations. A fund that uses fair value methodologies may value those securities higher or lower than another fund using market quotations or its own fair value methodologies to price the same securities. There can be no assurance that the fund could obtain the value assigned to a security if it were to sell the security at approximately the time at which the fund determines its net asset value. Investors who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the fund had not fair-valued the security or had used a different methodology.

Financial highlights

The financial highlights tables are intended to help you understand the performance of each class for the past five years, unless otherwise noted. No financial highlights are presented for Class FI, Class R or Class R1 shares because no Class FI, Class R or Class R1 shares were outstanding for the periods shown. The returns for Class FI, Class R and Class R1 shares will differ from those of the other classes to the extent that their expenses differ. Certain information reflects financial results for a single share. Total return represents the rate that a shareholder would have earned (or lost) on a fund share assuming reinvestment of all dividends and distributions. The information in the following tables has been derived from the fund’s and the predecessor fund’s financial statements, which have been audited by KPMG LLP, an independent registered public accounting firm, whose report, along with the fund’s financial statements, is included in the Annual Report (available upon request). The financial information shown below for periods prior to April 16, 2007 is that of the fund’s predecessor.
