Important Information

The fund seeks capital appreciation.

The fund’s investment objective may be changed by the Board of Trustees (the “Board”) without shareholder approval and on notice to shareholders.

There is no assurance that the fund will meet its investment objective.

The fund invests primarily in common stocks of companies the portfolio managers believe are experiencing, or will experience, growth in earnings exceeding the average rate of earnings growth of the companies which comprise the S&P 500 Index. The fund may invest in the securities of large, well-known companies offering prospects of long-term earnings growth. However, because higher earnings growth rates are often achieved by small to medium capitalization companies, a significant portion of the fund’s assets may be invested in the securities of such companies.

The fund’s investment strategies and policies may be changed from time to time without shareholder approval, unless specifically stated otherwise in this Prospectus or in the SAI.

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 (“REITs”).

Foreign investments

The fund may invest up to 25% of its net assets (at the time of investment) in foreign securities. The fund may invest directly in foreign issuers or invest in depositary receipts.

Short sales

A short sale is a transaction in which the fund sells securities it does not own in anticipation of a decline in the market price of the securities. The fund may hold no more than 25% of its net assets (taken at the then current market value) as required collateral for such sales at any one time.

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.

Investments by other funds

The fund may be an investment option for other funds, including affiliated 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, including by investing in any type of money market instruments, short-term debt securities or cash without regard to any percentage limitations. Although the subadviser 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.

Percentage and other limitations

The fund’s compliance with its investment limitations and requirements described in this Prospectus is usually determined at the time of investment. If such a percentage limitation is complied with at the time of an investment, any subsequent change resulting from a change in values or assets will not constitute a violation of that limitation.

Selection process

The portfolio managers emphasize individual security selection while diversifying the fund’s investments across industries, which may help to reduce risk. The portfolio managers focus primarily, but not exclusively, on emerging growth companies that have passed their “start-up” phase and show

positive earnings and the prospect of achieving significant profit gains beginning in the two to three years after the fund acquires their stocks. When evaluating an individual stock, the portfolio managers consider whether the company may benefit from:

More on 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. 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. If the market prices of the securities owned by the fund fall, the value of your investment in the fund will decline.

Market events risk. In the past several years financial markets, such as those in the United States, Europe, Asia and elsewhere, have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. Governmental and non-governmental issuers have defaulted on, or been forced to restructure, their debts. These conditions may continue, recur, worsen or spread.

The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, have taken steps to support financial markets, including by keeping interest rates at historically low levels. This and other government intervention may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. The Federal Reserve recently has reduced its market support activities. Further reduction or withdrawal of Federal Reserve or other U.S. or non-U.S. governmental or central bank support, including interest rate increases, could negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the fund invests.

Policy and legislative changes in the United States and in other countries are affecting many aspects of financial regulation, and may in some instances contribute to decreased liquidity and increased volatility in the financial markets. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.

Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the fund’s investments may be negatively affected.

Market sector risk. The fund may be significantly overweight to underweight certain companies, industries or market sectors, which may cause the fund’s performance to be more sensitive to developments affecting those companies, industries or sectors.

Large capitalization company risk. Large capitalization companies may fall out of favor with investors based on market and economic conditions. In return for the relative stability and low volatility of large capitalization companies, the fund’s value may not rise as much as the value of funds that focus on companies with smaller market capitalizations.

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.

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.

Table of Contents

Growth investing risk. The fund’s growth-oriented investment style may increase the risks of investing in the fund. Growth securities typically are quite sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth securities typically fall. Growth securities may also be more volatile than other investments because they often do not pay dividends.

Growth stocks as a group may be out of favor and underperform the overall equity market while the market concentrates on value stocks. Although the fund will not concentrate its investments in any one industry or industry group, it may, like many growth funds, weight its investments toward certain industries, thus increasing its exposure to factors adversely affecting issuers within those industries.

Foreign investments risk. The fund’s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the fund may invest may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions , reduction of government or central bank support and political or financial instability. Lack of information may also affect the value of these securities.

The value of the fund’s foreign investments may also be affected by foreign tax laws, special U.S. tax considerations and restrictions on receiving the investment proceeds from a foreign country. Dividends or interest on, or proceeds from the sale or disposition of, foreign securities may be subject to non-U.S. withholding or other taxes.

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. It may be difficult for the fund to pursue claims against a foreign issuer in the courts of a foreign country. Some securities issued by non-U.S. governments or their subdivisions, agencies and instrumentalities may not be backed by the full faith and credit of such governments. Even where a security is backed by the full faith and credit of a government, it may be difficult for the fund to pursue its rights against the government. Some non-U.S. governments have defaulted on principal and interest payments, and more may do so. In certain foreign markets, settlement and clearance procedures may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.

The risks of foreign investments are heightened when investing in issuers in emerging market countries.

Currency risk. The value of investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation.

Valuation risk. 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 illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods, such as fair value methodologies. Investors who purchase or redeem fund shares on days when the fund is holding fair- valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the fund had not fair-valued the security or had used a different valuation methodology. The value of foreign securities, certain fixed income securities and currencies, as applicable, may also be materially affected by events after the close of the markets on which they are traded, but before the fund determines its net asset value. The fund’s ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers.

Liquidity risk. Liquidity risk exists when particular investments are impossible or 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. Markets may become illiquid when, for instance, there are few, if any, interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. 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. The fund may experience heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value, which could cause the value of your investment to decline. 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.

Portfolio management risk. The value of your investment may decrease if the subadviser’s judgment about the attractiveness or value of, or market trends affecting a particular security, industry, sector or region, or about market movements is incorrect, or if there are imperfections, errors or limitations in the tools and data used by the subadviser. In addition, the fund’s investment strategies or policies may change from time to time. Those changes may not lead to the results intended by the subadviser and could have an adverse effect on the value or performance of the fund.

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

Short sales risk. If the price of the security sold short increases between the time of the short sale and the time the fund replaces the borrowed security, the fund will realize a loss, which may be substantial.

Redemptions by other funds and by other significant investors. The fund may be an investment option for other Legg Mason, Inc. (“Legg Mason”) sponsored mutual funds that are managed as “funds of funds,” unaffiliated mutual funds and other investors with substantial investments in the fund. As a result, from time to time, the fund may experience relatively large redemptions and could be required to liquidate its assets at inopportune times or at a loss or depressed value, which could cause the value of your investment to decline.

Cash management and defensive investing risk. The value of the investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, they are subject to risk, including market, interest rate and credit risk. If the fund holds cash uninvested it will be subject to the credit risk of the depository institution holding the cash. If the fund holds cash uninvested, the fund will not earn income on the cash. If a significant amount of the fund’s assets are used for cash management or defensive investing purposes, it may not achieve its investment objective.

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 average net assets decrease, as a result of redemptions or otherwise, or if a fee limitation is changed or terminated. Net assets are more likely to decrease and fund expense ratios are more likely to increase when markets are volatile.

Cybersecurity risk. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data (including private shareholder information), or proprietary information, or cause the fund, the manager, the subadvisers and/or its service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or lose operational functionality.

Operational risk. Your ability to transact with the fund or the valuation of your investment may be negatively impacted because of the operational risks arising from factors such as processing errors and human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel, and errors caused by third party service providers or trading counterparties. Although the fund attempts to minimize such failures through controls and oversight, it is not possible to identify all of the operational risks that may affect the fund or to develop processes and controls that completely eliminate or mitigate the occurrence of such failures. The fund and its shareholders could be negatively impacted as a result.

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.

This Prospectus and the SAI provide information concerning the fund that you should consider in determining whether to purchase shares of the fund. The fund may make changes to this information from time to time. Neither this Prospectus nor the SAI is intended to give rise to any contract rights or other rights in any shareholder, other than any rights conferred explicitly by federal or state securities laws that may not be waived.

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. From time to time, LMIS and/or financial intermediaries may agree to a reduction or waiver of these fees. 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 IS shares are not subject to distribution and/or service fees under the plan.

Additional payments

In addition to distribution and service fees and sales charges, 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 between the distributor, the manager and/or their affiliates, and the recipients of these payments.

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. Class C shares are not available for purchase through accounts where Legg Mason Investor Services, LLC is the broker-dealer of record (“LMIS Accounts”). Individual investors who invest directly with the fund and who meet the $1,000,000 minimum initial investment requirement may purchase Class I shares.

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:

When choosing between Class A and Class C shares, you should be aware that, generally speaking, the larger the size of your investment and the longer your investment horizon, the more likely it will be that Class C shares will 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 and service fees you would have paid for larger purchases of Class A shares. If you are eligible to purchase Class I shares, you should be aware that Class I shares are not subject to a front-end sales charge and generally have lower annual expenses than Class A or Class C shares.

Class R1 shares are closed to all new purchases and incoming exchanges.

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 IS 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 or Class R shares. You may be required to provide appropriate documentation confirming your eligibility to invest in Class FI or Class R 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 18 months 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 shares of funds sold by the distributor to take advantage of the breakpoints in the Class A 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.

Accumulation Privilege – allows you to combine the current value of shares of the fund with other shares of funds sold by the distributor that are owned by:

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. Shares of money market funds sold by the distributor that were not acquired by exchange from other funds offered with a sales charge may not be combined. Please contact your Service Agent or the fund for additional information.

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

Sales charges cont’d

Letter of Intent – allows you to purchase Class A shares of funds sold by the distributor over a 13-month period and pay the same sales charge, if any, as if all shares had been purchased at once. At the time you enter into the letter of intent, you select your asset goal amount. Generally, purchases of shares of funds sold by the distributor that are purchased during the 13-month period by:

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 the current value of any eligible holdings toward your asset goal amount.

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 asset goal amount.

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 asset goal amount. 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 based on the schedule of the fund that you originally purchased. 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.

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%. Class C shares are not available for purchase through LMIS Accounts.

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 and Class R shares at net asset value with no initial sales charge and no contingent deferred sales charge when redeemed. Class R1 shares are closed to all new purchases and incoming exchanges.

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 and Class IS shares

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

Table of Contents

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:

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, employer sponsored benefit plans (including health savings accounts), other similar employer-sponsored retirement and benefit plans, and individual retirement accounts that are administered on the same IRA recordkeeping platform and that invest in the fund through a single omnibus account pursuant to a special contractual arrangement with the fund or the distributor. Retirement Plans do not include individual retirement vehicles, such as traditional and Roth IRAs (absent an exception that is explicitly described in this Prospectus), 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 A, Class C, Class FI, Class R, Class I and Class IS shares.

Investors who rollover fund shares from a Retirement Plan into an individual retirement account administered on the same retirement plan platform may hold, purchase and exchange shares of the fund to the same extent as the applicable Retirement Plan.

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.

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 Plans” do not include arrangements whereby an investor would rollover fund shares from a Retirement Plan into an individual retirement account administered on the same retirement plan platform. Such arrangements are deemed to be “Retirement Plans” and are subject to the rights and privileges described under “Retirement and Institutional Investors — eligible investors — Retirement Plans.”

Other Retirement Plan investors can generally invest in Class A, Class C and Class I 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 A, Class FI, Class R or 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 and direct retail investment platforms through mutual fund “supermarkets,” where the sponsor links its client’s account (including IRA accounts on such platforms) to a master account in the sponsor’s name. The financial intermediary may impose separate investment minimums.

Clients of Eligible Financial Intermediaries may generally invest in Class A, Class FI, Class R or Class I shares. Class I shares are available for exchange from Class A or Class C shares of the fund by participants in the Eligible Investment Programs.

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 or Class IS 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

Retirement Plans may buy Class A shares. Under certain programs for current and prospective Retirement Plan investors sponsored by financial intermediaries, the initial sales charge and contingent deferred sales charge for Class A shares are waived where:

Retirement and Institutional Investors — eligible investors cont’d

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 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 be 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 Clients of Eligible Financial Intermediaries and Retirement Plans.

Class R shares

Class R shares are offered only to Retirement Plans with omnibus accounts held on the books of the fund (either at the plan level or at the level of the financial intermediary), to Clients of Eligible Financial Intermediaries and through Eligible Investment Programs.

Class R1 shares

Class R1 shares are closed to all new purchases and incoming exchanges.

Class I shares

Class I shares are offered only to Institutional Investors and individual investors (investing directly with the fund) who meet the $1,000,000 minimum initial investment requirement, Retirement Plans with omnibus accounts held on the books of the fund and certain rollover IRAs, 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.

Class IS shares

Class IS shares may be purchased only by Retirement Plans with omnibus accounts held on the books of the fund, certain rollover IRAs and Institutional Investors, and other investors authorized by LMIS. In order to purchase Class IS shares, an investor must hold its shares in one account with the fund, which account is not subject to payment of recordkeeping or similar fees by the fund to any intermediary.

Class B shares

The fund no longer offers Class B shares for purchase by new or existing investors. Institutional Investors and certain Retirement Plans that owned Class B shares 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.

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.

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. Generally, U.S. citizens residing in foreign countries will not be permitted to establish accounts with the fund. Neither the manager, the subadviser nor the fund is currently approved, registered or otherwise permitted to market to prospective investors which are domiciled in, or with a registered office in, any jurisdiction within the Member States of the European Union and the European Economic Area under any legislation implementing the Alternative Investment Fund Managers Directive (the “AIFMD”) and the supplementing Level 2 Delegated Regulation to the AIFMD in the relevant country.

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, subject to applicable law.

The fund has the right to:

For your protection, the fund or your Service Agent may request additional information in connection with large redemptions, unusual activity in your account, or otherwise to ensure your redemption request is in good order. Please contact your Service Agent or the fund for more information.

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

Table of Contents

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 next-to-last business day of the quarter (with an annual maximum of $15.00 per account). The small account fee will be charged 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 21 months. Payment of the small account fee through a redemption of fund shares 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 and 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 of 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).

The small account fee is calculated on a fund-by-fund basis. If you have accounts in multiple funds, they will not be aggregated for the purpose of calculating the small account fee. 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).

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 subadviser may need to allocate more assets to cash or other short-term investments or sell securities, rather than maintaining full investment in

Table of Contents

Other things to know about transactions cont’d

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 either preceded or 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.

Table of Contents

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 be entitled to vote your shares and may seek voting instructions from you. 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, other distributions and taxes

Dividends and other distributions

The fund generally pays dividends and distributes capital gain, if any, once in December and at such other times as are necessary. The fund may pay additional distributions and dividends in order to avoid a federal tax.

You can elect to receive dividends and/or other distributions in cash.

Unless you elect to receive dividends and/or other distributions in cash, your dividends and capital gain distributions will be automatically reinvested in shares of the same class you hold, at the net asset value determined on the reinvestment date. You do not pay a sales charge on reinvested distributions or dividends.

If you hold shares directly with the fund and you elect to receive dividends and/or distributions in cash, you have the option to receive such dividends and/or distributions via a direct deposit to your bank account or, provided that the dividend and/or distribution is $10.00 or more, by check. If you choose to receive dividends and/or distributions via check, amounts less than $10.00 will automatically be reinvested in fund shares as described above.

If you do not want dividends and/or distributions in amounts less than $10.00 to be reinvested in fund shares, you must elect to receive dividends and distributions via a direct deposit to your bank account.

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

To change those instructions, you must notify your Service Agent or 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 other distributions.

The Board reserves the right to revise the dividend policy or postpone the payment of dividends, if warranted in the Board’s judgment, due to unusual circumstances.

Taxes

The following discussion is very general, applies only to shareholders who are U.S. persons, and does not address shareholders subject to special rules, such as those who hold fund shares through an IRA, 401(k) plan or other tax-advantaged account. Except as specifically noted, the discussion is limited to federal income tax matters, and does not address state, local, foreign or non-income taxes. Further information regarding taxes, including certain federal income tax considerations relevant to non-U.S. persons, is included in the SAI. Because each shareholder’s circumstances are different and special tax rules may apply, you should consult your tax adviser about federal, state, local and/or foreign tax considerations that may be relevant to your particular situation.

In general, redeeming shares, exchanging shares and receiving dividends and distributions (whether received in cash or reinvested in additional shares or shares of another fund) are all taxable events. An exchange between classes of shares of the same fund normally is not taxable for federal income tax purposes, whether or not the shares are held in a taxable account.

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

Distributions of investment income that the fund reports as “qualified dividend income” may be eligible to be taxed to noncorporate shareholders at the reduced rates applicable to long-term capital gain if certain requirements are satisfied. Distributions of net capital gain reported by the fund as capital gain dividends are taxable to you as long-term capital gain regardless of how long you have owned your shares. Noncorporate shareholders ordinarily pay tax at reduced rates on long-term capital gain.

You may want to avoid buying shares when the fund is about to declare a dividend or capital gain distribution because it will be taxable to you even though it may economically represent a return of a portion of your investment.

Table of Contents

A Medicare contribution tax is imposed at the rate of 3.8% on net investment income of U.S. individuals with income exceeding specified thresholds, and on undistributed net investment income of certain estates and trusts. Net investment income generally includes for this purpose dividends and capital gain distributions paid by the fund and gain on the redemption or exchange of fund shares.

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. 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.

Table of Contents

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 the manager, which generally 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 R1 shares because no Class R1 shares were outstanding for the periods shown. The returns for 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 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).
