The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund 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 34% of the average value of its portfolio.

Under normal circumstances, between 50% and 70% of the Fund's total assets are invested in equity securities and between 30% and 50% of the Fund's total assets are invested in debt securities.

The Fund's equity investments may include common stocks, preferred stocks, securities convertible into common stocks, real estate investment trusts ("REITs"), American Depositary Receipts ("ADRs") and U.S. dollar-denominated foreign stocks traded on U.S. exchanges (collectively referred to as "stocks"). The Fund may invest in companies of all market capitalizations. The Manager allocates the assets of the Fund among different sub-advisors.

The Manager believes that this strategy may help the Fund outperform other investment styles over the longer term while reducing volatility and downside risk.

The Fund's sub-advisors select stocks that, in their opinion, have most or all of the following characteristics (relative to the S&P 500® Index):

above-average earnings growth potential,
below-average price to earnings ratio,
below-average price to book value ratio, and
above-average dividend yields.

Each of the Fund's sub-advisors determines the earnings growth prospects of companies based upon a combination of internal and external research using fundamental analysis and considering changing economic trends. The decision to sell a stock is typically based on the belief that the company is no longer considered undervalued or shows deteriorating fundamentals, or that better investment opportunities exist in other stocks. The Fund's debt securities may include: obligations of the U.S. Government, its agencies and instrumentalities, including U.S. Government-sponsored enterprises (some of which are not backed by the full faith and credit of the U.S. Government); U.S. and U.S. dollar-denominated foreign corporate debt securities, such as notes and bonds, mortgage-backed securities; asset-backed securities; master-demand notes and other debt securities.

The Fund will only buy debt securities that are deemed by the Manager or sub-advisors, as applicable, to be investment grade at the time of the purchase. If an investment held by the Fund is downgraded below investment grade, the Manager or sub-advisors, as applicable will take action that they believe to be advantageous to the Fund. The Fund has no limitations regarding the duration of the debt securities it can buy.

In determining which debt securities to buy and sell, the Manager and the sub-advisors generally use a "top-down" or "bottom-up" investment strategy, or a combination of both strategies. The top-down fixed-income investment strategy is implemented as follows:

Develop an overall investment strategy, including a portfolio duration target, by examining the current trends in the U.S. economy.
Set desired portfolio duration structure by comparing the differences between corporate and U.S. Government securities of similar duration to judge their potential for optimal return in accordance with the target duration benchmark.
Determine the weightings of each security type by analyzing the difference in yield spreads between corporate and U.S. Government securities.
Select specific debt securities within each security type.
Review and monitor portfolio composition for changes in credit, risk-return profile and comparisons with benchmarks.

The bottom-up fixed-income investment strategy is implemented as follows:

Search for eligible securities with a yield to maturity advantage versus a U.S. Government security with a similar duration.
Evaluate credit quality of the securities.
Perform an analysis of the expected price volatility of the securities to changes in interest rates by examining actual price volatility between U.S. Government and non-U.S. Government securities.

The Fund may invest cash balances in other investment companies and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs.

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of current income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund are:

Allocation and Correlation Risk
The Manager's and sub-advisor's judgments about, and allocations between, asset classes and market exposures may adversely affect the Fund's performance. This risk may be increased by the use of futures contracts to increase allocations to various market exposures.

Asset-Backed and Mortgage Related Securities Risk
Investments in asset-backed and mortgage related securities are subject to market risks for fixed-income securities which include, but are not limited to, interest rate risk, extension risk and prepayment risk.

Credit Risk
The Fund is subject to the risk that the issuer or guarantor of a debt security will fail to make timely payment of interest or principal or otherwise honor its obligations or default completely.

Equity Investments Risk
Equity securities are subject to market risk. The Fund's investments in equity securities may include common stocks, preferred stocks, securities convertible into or exchangeable for common stocks, depositary receipts, REITs, and U.S. dollar-denominated foreign stocks traded on U.S. exchanges. Such investments may expose the Fund to additional risks. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company. Preferred stocks and convertible securities are sensitive to movements in interest rates. In addition, convertible securities are subject to the risk that the credit standing of the issuer may have an effect on the convertible securities' investment value. Investments in REITs are subject to the risks associated with investing in the real estate industry such as adverse developments affecting the real estate industry and real property values. Depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency fluctuations and political and financial instability in the home country of a particular depositary receipt or foreign stock.

Futures Contract Risk
Futures contracts are derivative instruments where one party pays a fixed price for an agreed amount of securities or other underlying assets at an agreed date or to buy or sell a specific currency at a future date at a price set at the time of the contract. The use of such derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience potentially dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index which will increase the volatility of the Fund and may involve a small investment of cash relative to the magnitude of the risk assumed. There can be no assurance that any strategy used will succeed. There may not be a liquid secondary market for the futures contract. When the Fund purchases or sells a futures contract, it is subject to daily variation margin calls that could be substantial in the event of adverse price movements. If the Fund has insufficient cash to meet daily variation margin requirements, it might need to sell securities at a time when such sales are disadvantageous.

Interest Rate Risk
The Fund is subject to the risk that the market value of fixed income securities or derivatives it holds, particularly mortgage backed and other asset backed securities, will decline due to rising interest rates. When interest rates rise, the prices of most fixed income securities go down. As of the date of this Prospectus, interest rates are at or near historic lows, but may rise substantially and/or rapidly, potentially resulting in substantial losses to the Fund. The prices of fixed income securities or futures contracts are also affected by their duration. Fixed income securities or futures contracts with longer duration generally have greater sensitivity to changes in interest rates. For example, if a bond has a duration of four years, a 1% increase in interest rates could be expected to result in a 4% decrease in the value of the bond.

Investment Risk
An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Issuer Risk
The value of a security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets.

Large Capitalization Companies Risk
The securities of large market capitalization companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.

Market Risk
Market risks, including political, regulatory, market and economic developments, and developments that impact specific economic sectors, industries or segments of the market, can affect the value of the Fund's shares. The Fund's fixed-income investments are subject to the risk that events in the fixed-income markets may lead to periods of volatility, unusual liquidity issues and, in some cases, credit downgrades and increased likelihood of default. The Fund's equity investments are subject to stock market risk, which involves the possibility that the value of the Fund's investments in stocks will decline due to volatility or drops in any of the many individual country or global financial markets. Such events may cause the value of securities owned by the Fund to go up or down, sometimes rapidly or unpredictably, and may lead to increased redemptions, which could cause the Fund to experience a loss when selling securities to meet redemption requests by shareholders.

Other Investment Companies Risk
The Fund may invest in shares of other registered investment companies, including money market funds. To the extent that the Fund invests in shares of other registered investment companies, you will indirectly bear fees and expenses charged by the underlying funds in addition to the Fund's direct fees and expenses and will be subject to the risks associated with investments in those funds.

Prepayment and Extension Risk
The Fund's investments in asset-backed and mortgage-backed securities are subject to the risk that the principal amount of the underlying collateral may be repaid prior to the bond's maturity date. If this occurs, no additional interest will be paid on the investment and the Fund may have to invest at a lower rate. Conversely, a decrease in expected prepayments may result in the extension of a security's effective maturity and a decline in its price.

Redemption Risk
Due to a rise in interest rates or other changing government policies that may cause investors to move out of fixed income securities on a large scale, the Fund may experience periods of heavy redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value.

Securities Selection Risk
Securities selected by the sub-advisor or the Manager for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objectives.

Segregated Assets Risk
In connection with certain transactions that may give rise to future payment obligations, including futures contracts, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the position, which cannot be sold while the position they are covering is outstanding, unless they are replaced with other securities of equal value.

Small and Mid-Capitalization Companies Risk
Investing in the securities of small and mid-capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies. Since small and mid-capitalization companies may have limited operating history, product lines, and financial resources, the securities of these companies may lack sufficient market liquidity, and they can be particularly sensitive to expected changes in interest rates, borrowing costs and earnings.

U.S. Government Securities and Government Sponsored Enterprises Risk
A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed by the applicable entity only as to the timely payment of interest and principal when held to maturity. The market prices for such securities are not guaranteed and will fluctuate. Securities held by the Fund that are issued by government-sponsored enterprises, such as the Federal National Mortgage Association (''Fannie Mae''), the Federal Home Loan Mortgage Corporation (''Freddie Mac''), Federal Home Loan Banks, Federal Farm Credit Banks, and the Tennessee Valley Authority are not guaranteed by the U.S. Treasury and are not backed by the full faith and credit of the U.S. Government. U.S. Government securities and securities of government sponsored enterprises are also subject to credit risk, interest rate risk and market risk.

Value Stocks Risk
Value stocks are subject to the risk that their intrinsic value may never be realized by the market or that their prices may go down. While the Fund's investments in value stocks may limit its downside risk over time, the Fund may produce more modest gains than riskier stock funds as a trade-off for this potentially lower risk. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.

The bar chart and table below provide an indication of risk by showing how the Fund's performance has varied from year to year. The table shows how the Fund's performance compares to a broad-based market index, which is the Fund's benchmark index, a secondary index and a composite index. The chart and the table show the performance of the Fund's Investor Class shares for all periods. The Fund began offering Institutional Class Shares on July 17, 1987, Investor Class shares on August 1, 1994, Advisor Class shares on May 31, 2005, Y Class shares on March 1, 2010, A Class shares on May 17, 2010 and C Class shares on September 1, 2010. In the table below, the performance of the Institutional Class shares is shown for the Y Class shares and the performance of the Investor Class shares is shown for the Advisor Class, A Class and C Class shares, prior to the dates such newer classes were first offered. In each case, the older share classes would have had similar annual returns to the newer share classes because the shares are invested in the same portfolio securities. However, the older share classes had different expenses than the newer share classes. You may obtain updated performance information on the Fund's website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Average annual total returns for periods ended December 31, 2014

After-tax returns are shown only for Investor Class shares; after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. If you hold your Fund shares through a tax-deferred arrangement, such as an IRA or a 401(k), the after-tax returns do not apply to your situation

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund 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 29% of the average value of its portfolio.

Under normal circumstances, at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes) are invested in equity securities of large market capitalization U.S. companies. These companies have market capitalizations within the market capitalization range of the companies in the Russell 1000® Index at the time of investment. The Russell 1000 Index measures the performance of the 1,000 largest U.S. companies based on total market capitalization. As of January 31, 2015, the market capitalizations of the companies in the Russell 1000 Index ranged from $201 million to $706.4 billion.

The Fund's investments may include common stocks, preferred stocks, securities convertible into U.S. common stocks, real estate investment trusts ("REITs"), American Depositary Receipts ("ADRs") and U.S. dollar-denominated foreign stocks traded on U.S. exchanges (collectively referred to as "stocks").

Sector Risk
Sector risk is the risk associated with the Fund holding a significant amount of investments in similar businesses, which could be affected by the same economic or market conditions.

Securities Selection Risk
Securities selected by the sub-advisors or the Manager for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objectives.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund 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 24% of the average value of its portfolio.

Under normal circumstances, at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes) are invested in equity securities of middle market capitalization U.S. companies. These companies have market capitalizations within the market capitalization range of the companies in the Russell Midcap® Index at the time of investment. As of January 31, 2015 the market capitalizations of the companies in the Russell Midcap Index ranged from $201 million to $35.2 billion. The Fund's investments may include common stocks, preferred stocks, securities convertible into U.S. common stocks, real estate investment trusts ("REITs"), American Depositary Receipts ("ADRs") and U.S. dollar-denominated foreign stocks traded on U.S. exchanges (collectively referred to as "stocks").

The Manager allocates the assets of the Fund among different sub-advisors. The Manager believes that this strategy may help the Fund outperform other investment styles over the longer term while reducing volatility and downside risk.

In general, the sub-advisors select stocks that, in their opinion, have most or all of the following characteristics (relative to the Russell Midcap Index):

above-average earnings growth potential,
below-average price to earnings ratio,
below-average price to book value ratio, and
above-average dividend yields.

One sub-advisor invests in medium-sized companies with low price to earnings and price to book value ratios and high dividend yields in relation to the Russell Midcap Index. Through extensive research and meetings with company management teams, the sub-advisor seeks to identify companies that not only possess these three characteristics, but that also exhibit high or improving profitability translating into earnings growth above that of the overall Russell Midcap Index. The sub-advisor's portfolio will generally consist of 35 to 45 stocks.

The second sub-advisor invests in medium-sized companies and intends to maintain a concentrated portfolio of 30 to 40 stocks selected from the most undervalued or "deep" value portion of its investment universe. That sub-advisor looks for companies within that universe that sell for a low price relative to normal earnings (with "normal earnings" defined as a 5 year estimate of what the company should earn in a normal environment based on research of the company's history and the history of its industry).

The third sub-advisor utilizes a classic value-driven philosophy based on the belief that leading businesses selling at a discount to fair value have the potential to generate excess returns. The strategy focuses on stocks that are temporarily out of favor in the market; specifically, companies with higher returns on capital, free cash flow and strong balance sheets. These companies often dominate a particular industry niche, generally have significant barriers to entry and, as a result, are able to perpetuate a higher return on capital over time.

Each of the Fund's sub-advisors determines the earnings growth prospects of companies based upon a combination of internal and external research using fundamental analysis and considering changing economic trends. The decision to sell a security is typically based on the belief that the company is no longer considered undervalued or shows deteriorating fundamentals, or that better investment opportunities exist in other stocks.

The Fund may invest cash balances in other investment companies and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs.

The Fund may lend its securities to broker-dealer and other institutions to earn additional income.

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of income and is intended to be a long-term investment.

Equity Investments Risk
Equity securities are subject to market risk. The Fund's investments in equity securities may include common stocks, preferred stocks, securities convertible into or exchangeable for common stocks, depositary receipts, REITs, and U.S. dollar-denominated foreign stocks traded on U.S. exchanges. Such investments may expose the Fund to additional risks. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company. Preferred stocks and convertible securities are sensitive to movements in interest rates. In addition, convertible securities are subject to the risk that the credit standing of the issuer may have an effect on the convertible securities' investment value. Investments in REITs are subject to the risks associated with investing in the real estate industry such as adverse developments affecting the real estate industry and real property values. Depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency fluctuations and political and financial instability in the home country of a particular depositary receipt or foreign stock.

Futures Contracts Risk
Futures contracts are derivative investments pursuant to a contract with a counterparty to pay a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract). There can be no assurance that any strategy used will succeed.

There may not be a liquid secondary market for the futures contract. When the Fund purchases or sells a futures contract, it is subject to daily variation margin calls that could be substantial in the event of adverse price movements. If the Fund has insufficient cash to meet daily variation margin requirements, it might need to sell securities at a time when such sales are disadvantageous.

Investment Risk
An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Issuer Risk
The value of a security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets.

Market Risk
Market risks, including political, regulatory, market and economic developments, and developments that impact specific economic sectors, industries or segments of the market, can affect the value of the Fund's shares. The Fund's equity investments are subject to stock market risk, which involves the possibility that the value of the Fund's investments in stocks will decline due to volatility or drops in any of the many individual country or global financial markets. Such events may cause the value of securities owned by the Fund to go up or down, sometimes rapidly or unpredictably, and may lead to increased redemptions, which could cause the Fund to experience a loss when selling securities to meet redemption requests by shareholders.

Mid-Capitalization Companies Risk
Investing in the securities of medium capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization companies and more established companies. Since mid-sized companies may have limited operating history, product lines, and financial resources, the securities of these companies may lack sufficient market liquidity, and can be sensitive to expected changes in interest rates, borrowing costs and earnings.

Other Investment Companies Risk
The Fund may invest in shares of other registered investment companies, including money market funds. To the extent that the Fund invests in shares of other registered investment companies, you will indirectly bear fees and expenses charged by the underlying funds in addition to the Fund's direct fees and expenses and will be subject to the risks associated with investments in those funds.

Sector Risk
Sector risk is the risk associated with the Fund holding a significant amount of investments in similar businesses, which could be affected by the same economic or market conditions.

Securities Lending Risk
To the extent the Fund lends its securities, it may be subject to the following risks. Borrowers of the Fund's securities typically provide collateral in the form of cash that is reinvested in securities. The securities in which the collateral is invested may not perform sufficiently to cover the return collateral payments owed to borrowers. In addition, delays may occur in the recovery of securities from borrowers, which could interfere with the Fund's ability to vote proxies or to settle transactions.

Securities Selection Risk
Securities selected by the sub-advisors or the Manager for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objectives.

Segregated Assets Risk
In connection with certain transactions that may give rise to future payment obligations, including futures contracts, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the position, which cannot be sold while the position they are covering is outstanding, unless they are replaced with other securities of equal value.

Value Stocks Risk
Value stocks are subject to the risk that their intrinsic value may never be realized by the market or that their prices may go down. While the Fund's investments in value stocks may limit its downside risk over time, the Fund may produce more modest gains than riskier stock funds as a trade-off for this potentially lower risk. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment. The Fund's value style could cause the Fund to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

The bar chart and table below provide an indication of risk by showing how the Fund's performance has varied from year to year. The table shows how the Fund's performance compares to a broad-based market index. The chart and the table show the performance of the Fund's Investor Class shares for all periods. The Fund began offering Institutional Class shares on November 30, 2005, Investor Class shares on March 1, 2006, Advisor Class shares on June 30, 2007, Y Class shares on March 1, 2010, A Class shares on May 17, 2010 and C Class shares on September 1, 2010. In the table below, the performance of the AMR Class of the Fund, which began offering shares on June 30, 2004 and is not offered in this prospectus, is shown for the Institutional Class shares before the date such class was first offered. For the Investor Class, performance results from June 30, 2004 to November 30, 2005 are for the AMR Class and performance results from November 30, 2005 to March 1, 2006 are for the Institutional Class. For the Advisor Class, performance results from June 30, 2004 to November 30, 2005 are for the AMR Class, performance results from November 30, 2005 to March 1, 2006 are for the Institutional Class and performance results from March 1, 2006 to June 30, 2007 are for the Investor Class. For Y Class, A Class and C Class shares, performance results from June 30, 2004 to November 30, 2005 are for the AMR Class and performance results from November 30, 2005 to the inception of the Y Class, A Class and C Class shares are for the Institutional Class. In each case, the older share classes would have had similar annual returns to the newer share classes because the shares are invested in the same portfolio securities. However, the older share classes had different expenses than the newer share classes. You may obtain updated performance information on the Fund's website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Average annual total returns for periods ended December 31, 2014

After-tax returns are shown only for Investor Class shares; after-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. If you hold your Fund shares through a tax-deferred arrangement, such as an IRA or a 401(k), the after-tax returns do not apply to your situation

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund 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 73% of the average value of its portfolio.

Under normal circumstances, at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes) are invested in equity securities of small market capitalization companies. These companies have market capitalizations of $5 billion or less at the time of investment. The Fund's investments may include common stocks, preferred stocks, securities convertible into common stocks, real estate investment trusts ("REITs"), American Depositary Receipts ("ADRs") and U.S. dollar-denominated foreign stocks traded on U.S. exchanges (collectively, "stocks").

The Manager allocates the assets of the Fund among different sub-advisors. The Manager believes that this strategy may help the Fund outperform other investment styles over the longer term while reducing volatility and downside risk. The sub-advisors select stocks that, in their opinion, have most or all of the following characteristics (relative to the Russell 2000® Index):

above-average earnings growth potential,
below-average price to earnings ratio,
below-average price to book value ratio
below-average price to revenue ratios, and
above average free cash flow yields and return on capital.

Each of the sub-advisors determines the earnings growth prospects of companies based upon a combination of internal and external research using fundamental analysis and considering changing economic trends. The process is research driven and takes into consideration items such as a company's tangible assets, sustainability of its cash flows, capital intensity and financial leverage.

One of the sub-advisors manages two allocations of the Fund's assets, one pursuant to the fundamental research strategy discussed above and the other pursuant to a quantitative application of its fundamental research process ("Quantitative Strategy"). The sub-advisor implements the Quantitative Strategy by using a quantitative multi-factor model that identifies the factors present in the sub-advisor's fundamental research portfolio, which may include, for example, below-average price-to-revenue ratios, price-to-earnings ratios and price-to-book ratios and above-average free cash flow yields and return on capital. The model applies these factors and factor weightings to the Russell 2000 Index universe of companies and makes recommendations for adjustments to the portfolio on a daily basis.

For each sub-advisor, the decision to sell a stock is typically based on the belief that the company is no longer considered undervalued or shows deteriorating fundamentals, or that better investment opportunities exist in other stocks.

The Fund may invest cash balances in other investment companies and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs.

The Fund may lend its securities to broker-dealers and other institutions to earn additional income.
