Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same, except that the example reflects the fee waiver/expense reimbursement arrangement for each share class through December 31, 2016. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example - (American Beacon Zebra Small Cap Equity Fund℠) - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	700	1,093	1,510	2,670
Class C	308	777	1,372	2,984
Class Y	102	450	823	1,870
Institutional Class	92	430	792	1,811
Investor Class	130	522	939	2,103

Assuming no redemption of shares:

Class C | USD ($)	208	777	1,372	2,984

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover 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 97% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, 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 U.S. companies. These companies have market capitalizations similar to the market capitalizations of the companies in the Russell 2000® Index at the time of investment.

The Russell 2000® Index is comprised of the 2000 companies at the bottom of the Russell 3000® Index based on total market capitalization. As of September 30, 2015, the market capitalizations of the companies in the Russell 2000® Index ranged from $38 million to $5.15 billion. In addition to common stocks, preferred stocks, American Depositary Receipts ("ADRs"), and securities convertible into or exchangeable for common stocks, the Fund may also invest in real estate investment trusts ("REITs") and master limited partnerships ("MLPs").

The Fund's sub-advisor, Zebra Capital Management, LLC ("Zebra"), seeks to capture a liquidity premium among fundamentally strong, publicly-traded equities. A liquidity premium is the additional return that may be realized on the sales of securities that are less liquid at the time of purchase. A liquidity premium may exist in public equity markets, as more liquid stocks tend to be priced at a premium, while less liquid stocks are priced at a discount, thus having higher expected appreciation. Despite producing similar levels of earnings and cash flows, these less liquid stocks can often be purchased at lower prices, offering higher expected appreciation. Frequently, a fundamentally-sound stock is less traded because it has temporarily fallen out of favor. Over time, the market may recognize the inherent value of the stock again, where the Fund would stand to benefit from the liquidity premium as the stock's trading activity and price rise. Zebra chooses the securities that comprise the Fund's portfolio first by identifying stocks with strong fundamentals (i.e., earnings, book value, cash flows) that Zebra believes are undervalued in the market relative to their long-term appreciation potential. Zebra then applies the liquidity premium analysis to identify the stocks that trade less frequently than stocks with comparable fundamentals.

Stocks are typically sold when fundamentals deteriorate, trading activity increases relative to changes in a stock's fundamentals, or Zebra believes there are greater opportunities to capture liquidity premium in other stocks. On a short-term basis, the Fund may invest cash balances in money market funds 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.

Principal Risks

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. 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:

Dividend Risk
An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks.

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, REITs, depositary receipts, and MLPs. Such investments may expose the Fund to additional risks. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. 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. Preferred stocks may be less liquid than common stocks and, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred stocks generally are payable at the discretion of an issuer and after required payments to bond holders. Convertible securities are subject to the risk that the credit standing of the issuer may have an effect on the convertible securities' investment value. Depositary receipts are subject to certain of the risks associated with investing directly in foreign securities, including currency exchange rate fluctuations, political and financial instability, less liquidity and more volatility, less government regulation and supervision and delays in transaction settlement. 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. Investments in MLPs are subject to certain risks that differ from investment in common stock. Holders of units in MLPs have more limited rights and may be required to sell their common units at an undesirable time or price. The Fund's investments in MLPs may also make it more difficult for the Fund to meet the requirements necessary to qualify as a regulated investment company under the Internal Revenue Code of 1986, as amended.

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. 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 (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).

Investment Risk
An investment in the Fund is not a deposit with 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, and/or the return generated by, 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.

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may have limited marketability or be subject to restrictions on sale, and may be difficult to sell at favorable times or prices. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund.

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. Turbulence in financial markets and reduced liquidity in credit, fixed-income, or equity markets may negatively affect many issuers worldwide which could adversely affect the Fund.

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, the Fund will indirectly bear the 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. For example, money market funds are subject to interest rate risk, credit risk, and market risk.

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-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 the purchase and sale of futures contracts, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the position or transaction, which cannot be sold while the position they are covering is outstanding, unless they are replaced with other assets of equal value.

Small Capitalization Companies Risk
Investing in the securities of small capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies. Since smaller 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.

Fund Performance

The bar chart and table below provide an indication of the risk of investing in the Fund 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.

The chart and the table below show the performance of the Fund's Investor Class shares for all periods. The Fund began offering A Class shares, Y Class shares, Institutional Class shares and Investor Class shares on June 1, 2010; and C Class shares on September 1, 2010. In the table below, the performance of the Investor Class shares is shown for the C Class shares prior to the date the C Class shares were first offered. The Investor Class shares and C Class shares would have had similar annual returns because the shares are invested in the same portfolio securities. However, Investor Class shares and C Class shares have different expenses.

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.

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 income 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 individual retirement account or a 401(k) plan, the after-tax returns do not apply to your situation. After-tax returns are shown only for Investor Class shares; after-tax returns for other share classes will vary.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover 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 43% of the average value of its portfolio.

Principal Investment Strategies

This Fund seeks to maximize current income by investing in a diversified portfolio of fixed income securities that are generally rated below investment grade (such as Ba or lower by Moody's Investors Service, Inc. or BB or lower by Standard & Poor's Ratings Services or Fitch, Inc.) or deemed to be below investment grade by Strategic Income Management, LLC ("SiM"). These types of securities are commonly referred to as "high yield" or "junk" bonds.

The Fund seeks its investment objective by investing, under normal circumstances, at least 80% of the Fund's net assets in non-investment grade securities and/or financial instruments that provide exposure to non-investment grade securities. These financial instruments include futures contracts (including futures contracts on stock indices and currencies), forward contracts (including currency forward contracts), swap agreements and structured notes whose underlying assets are rated below investment grade.

The non-investment grade securities in which the Fund may invest include: corporate bonds, convertible securities, preferred stock, bank and senior loans, floating rate loans, emerging market debt, municipal securities, asset-backed and mortgage-backed securities, and Rule 144A securities. The Fund may invest in securities of foreign issuers, including those in emerging markets. The Fund has no limitations regarding the maturities of the debt securities it can buy, the market capitalization of the issuers of those securities or whether the securities are rated.

The Fund's investments in derivative instruments include futures contracts, forward contracts, and swaps. The Fund may use these derivative instruments to enhance total return, to hedge against fluctuations in securities prices, interest rates or currency exchange rates, to manage the effective duration of its portfolio, and to manage certain investment risks or as a substitute for purchase or sale of the underlying currencies or securities.

The Fund may have exposure to foreign currencies for investment or hedging purposes by purchasing or selling forward currency exchange contracts in non-U.S. or emerging market currencies, and non-U.S. currency futures contracts. The Fund may also make direct investments in non-U.S. currencies and in securities denominated in non-U.S. currencies. Investments in currencies and currency hedging are established to extract value or reduce risk.

The remainder of the Fund's assets may be invested in any other securities that SiM believes are consistent with the Fund's objective, including investment grade fixed-income securities, U.S. government securities, common stock, American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs"), real estate investment trusts ("REITs"), loan participation interests, and income-producing equity securities, such as master limited partnerships ("MLPs"), and income trusts and income deposit securities ("IDSs"). The Fund may invest cash balances in exchange-traded funds to gain market exposure on cash balances.

In selecting investments for the Fund, SiM uses an approach that combines different aspects of top down and bottom up analysis. As part of its top down analysis, SiM utilizes a core philosophy to identify positive long term trends. SiM then invests in sectors, industries and companies that will benefit from these trends. Concurrent with this core philosophy, SiM's management seeks to take advantage of market volatility by analyzing and potentially investing in sectors, industries and companies undergoing a change in dynamics that has not been fully recognized by the market. Market volatility continually provides opportunities to capture value from these types of situations. Once potential investment opportunities are identified, SiM utilizes bottom up research to assess the fundamental strengths and weaknesses of each individual company and the best risk/reward security is chosen for inclusion in the portfolio.

SiM may reduce or sell the Fund's portfolio securities for a variety of reasons, including if, in SiM's opinion, a security's value becomes fully recognized or there is a reassessment of the fundamental attributes of the security.

Principal Risks

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your money by investing in the Fund. The Fund is designed primarily for investors seeking current income from a fund that typically invests mainly in a variety of domestic and foreign high-yield, high-risk debt securities. Those investors should be willing to assume the credit risks of a fund that typically invests a significant amount of its assets in below investment-grade debt securities and the price changes in those securities that can occur when interest rates change. The Fund is not designed for investors who need an assured level of current income. The Fund 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 Risk
The 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 derivatives 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, prepayment risk and extension risk.

Convertible Securities Risk
The value of a convertible security typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the risks of stocks when the underlying stock's price is high relative to the conversion price and is subject to the risks of debt securities when the underlying stock's price is low relative to the conversion price. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as "junk bonds"). In addition, because companies that issue convertible securities may be small- or mid-cap companies, to the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies. The stocks of small- and mid-cap companies may fluctuate more widely in price than the market as a whole and there may also be less trading in small- or mid-cap stocks.

Counterparty Risk
The Fund is subject to the risk that a party or participant to a transaction, such as a broker or derivative counterparty, will be unwilling or unable to satisfy its obligation to make timely principal, interest or settlement payments or to otherwise honor its obligations to the Fund.

Credit Risk
The Fund is subject to the risk that the issuer or guarantor of a debt security, or the counterparty to a derivatives contract or a loan will fail to make timely payment of interest or principal or otherwise honor its obligations or default completely. Credit risk is typically greater for securities with ratings that are below investment grade (commonly referred to as "junk bonds"). Since the Fund can invest significantly in lower-quality debt securities considered speculative in nature, this risk will be substantial.

Currency Risk
The Fund may have exposure to foreign currencies by purchasing or selling forward currency contracts in non-U.S. currencies, non-U.S. currency futures contracts and in securities denominated in non-U.S. currencies. Foreign currencies may decline in value relative to the U.S. dollar and affect the Fund's investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, or in derivatives that provide exposure to, foreign (non-U.S.) currencies.

Derivatives Risk
Derivatives may involve significant risk. The use of 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, including the high degree of leverage often embedded in such instruments, and potential material and prolonged deviations between the theoretical value and realizable value of a derivative. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. Derivatives may be illiquid and may be more volatile than other types of investments. The Fund may buy or sell derivatives not traded on an exchange and which may be subject to heightened liquidity and valuation risk. Derivative investments can increase portfolio turnover and transaction costs. Derivatives also are subject to counterparty risk. As a result the Fund may obtain no recovery of its investment or may only obtain a limited recovery, and any recovery may be delayed. Not all derivative transactions require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty. In addition, the Fund's investments in derivatives are subject to the following risks:

• Futures and Forward Contracts. Futures and forward contracts, including non-deliverable forwards ("NDFs"), are derivative instruments pursuant to a contract 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. There may be an imperfect correlation between the movement in the prices of futures contracts and the value of their underlying instruments or indexes. There can be no assurance that any strategy used will succeed. Not all forward contracts, including NDRs, require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty. There may not be a liquid secondary market for the futures contracts. Forward currency transactions, including NDRs, include the risks associated with fluctuations in currency. Interest rate and Treasury futures contracts expose the Fund to price fluctuations resulting from changes in interest rates. The Fund could suffer a loss if interest rates rise after the Fund has purchased an interest rate futures contract or fall after the Fund has sold an interest rate futures contract. Similarly, Treasury futures contracts expose the Fund to potential losses if interest rates do not move as expected.

• Structured Notes. Structured notes are derivative debt instruments with principal and/or interest payments linked to the value of a commodity, a foreign currency, an index of securities, an interest rate or other financial indicators ("reference instruments"). The payments on a structured note may vary based on changes in one or more specified reference instruments, such as a floating interest rate compared to a fixed interest rate, the exchange rates between two currencies, one or more securities or a securities or commodities index. A structured note may be positively or negatively indexed. Structured notes are subject to interest rate risk. They are also subject to credit risk with respect both to the issuer and, if applicable, to the underlying security or borrower. If the underlying investment or index does not perform as anticipated, the structured note might pay less interest than the stated coupon payment or repay less principal upon maturity.

• Swap Agreements. Swaps can involve greater risks than a direct investment in an underlying asset because swaps typically include a certain amount of embedded leverage. If swaps are used as a hedging strategy, the Fund is subject to the risk that the hedging strategy may not eliminate the risk that it is intended to offset, due to, among other reasons, the occurrence of unexpected price movements or the non-occurrence of expected price movements. Swaps also may be difficult to value. Equity swaps are subject to liquidity risk and counterparty risk. Total return swaps and currency swaps are subject to counterparty risk, credit risk and liquidity risk. In addition to these risks, total return swaps are subject to market risk and interest rate risk, if the underlying securities are bonds or other debt obligations. In addition, currency swaps are subject to currency risk.

Dividend Risk
An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks.

Emerging Markets Risk
When investing in emerging markets, the risks of investing in foreign securities discussed below are heightened. Emerging markets are generally smaller, less developed, less liquid and more volatile than the securities markets of the U.S. and other developed markets. There are also risks of: greater political uncertainties; an economy's dependence on revenues from particular commodities or on international aid or development assistance; currency transfer restrictions; a limited number of potential buyers for such securities; and delays and disruptions in securities settlement procedures.

Equity Investments Risk
Equity securities are subject to market risk. The Fund's investments in equity securities may include common stocks, preferred stocks, depositary receipts, REITs, MLPs, income trusts and IDSs. Such investments may expose the Fund to additional risks. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company. Preferred stocks may be less liquid than common stocks and, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred stocks generally are payable at the discretion of an issuer and after required payments to bond holders. Depositary receipts are subject to certain of the risks associated with investing directly in foreign securities. 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. Holders of units in MLPs have more limited rights and may be required to sell their common units at an undesirable time or price. The Fund's investments in MLPs may also make it more difficult for the Fund to meet the requirements necessary to qualify as a regulated investment company under the Internal Revenue Code of 1986, as amended. Income trusts and IDSs are subject to credit risk, interest rate risk and dividend risk. Income trusts, which hold income producing assets and pass the income on to security holders, share many of the risks inherent in stock ownership and may lack diversification. Although IDS, which are units representing shares of common stock and subordinated notes issued by a company, trade on an exchange,there may be a thinner and less active market for IDSs than that available for other securities. The value of an IDS will be affected by factors generally affecting both common stock and subordinated debt securities.

Floating Rate Securities Risk
The interest rates payable on floating rate securities are not fixed and may fluctuate based upon changes in market rates. The interest rate on a floating rate security is a variable rate which is tied to another interest rate, such as a money-market index or Treasury bill rate. Floating rate securities are subject to interest rate risk and credit risk.

As short-term interest rates decline, interest payable on floating rate securities typically should decrease. Alternatively, during periods of increasing interest rates, changes in the interest rates of floating rate securities may lag behind changes in market rates or may have limits on the maximum increases in interest rates. The value of floating rate securities may decline if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity and greater volatility, (4) lack of uniform accounting, auditing and financial reporting standards, (5) increased price volatility, (6) less government regulation and supervision of foreign stock exchanges, brokers and listed companies; and (7) delays in transaction settlement in some foreign markets.

Hedging Risk
If the Fund uses a hedging instrument at the wrong time or judges the market conditions incorrectly, or the hedged instrument does not correlate to the risk sought to be hedged, the hedge might be unsuccessful, reduce the Fund's return, or create a loss.

High Yield Securities Risk
Investing in high yield, below investment-grade securities (commonly referred to as "junk bonds") generally involves significantly greater risks of loss of your money than an investment in investment grade securities. High yield debt securities may fluctuate more widely in price and yield and may fall in price when the economy is weak or expected to become weak. High yield securities are considered to be speculative with respect to an issuer's ability to pay interest and principal and carry a greater risk that the issuers of lower-rated securities will default on the timely payment of principal and interest. Below investment grade securities may experience greater price volatility and less liquidity than investment grade securities.

Illiquid and Restricted Securities Risk
Securities not registered in the U.S. under the Securities Act of 1933, as amended (the "Securities Act"), including Rule 144A securities, may not be listed on an exchange and may have no active trading market. They may be more difficult to purchase or sell at an advantageous time or price because such securities may not be readily marketable in broad public markets. The Fund may not be able to sell a restricted security when the sub-advisor considers it desirable to do so and/or may have to sell the security at a lower price than the Fund believes is its fair market value. In addition, transaction costs may be higher for restricted securities and the Fund may receive only limited information regarding the issuer of a restricted security. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delays in effecting the registration.

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. As of the date of this Prospectus, interest rates are near historic lows, but may rise substantially and/or rapidly, potentially resulting in substantial losses to the Fund. Generally, the value of investments with interest rate risk, such as fixed income securities, will move in the opposite direction to movements in interest rates. The prices of fixed income securities or derivatives are also affected by their duration. Fixed income securities or derivatives with longer duration generally have greater sensitivity to changes in interest rates. For example, if a bond has a duration of eight years, a 1% increase in interest rates could be expected to result in a 8% decrease in the value of the bond. An increase in interest rates can impact markets broadly as well. For example, some investors buy securities and derivatives with borrowed money; an increase in interest rates can cause a decline in those markets.

Investment Risk
An investment in the Fund is not a deposit with 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, and/or the return generated by, 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.

Leverage Risk
The Fund's use of futures, forward contracts, swaps, structured notes, other derivative instruments and selling securities short will have the economic effect of financial leverage. Financial leverage magnifies the exposure to the swings in prices of an asset or class of assets underlying a derivative instrument and results in increased volatility, which means that the Fund will have the potential for greater losses than if the Fund does not use the derivative instruments that have a leveraging effect. Leverage may result in losses that exceed the amount originally invested and may accelerate the rate of losses. Leverage tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund's exposure to an asset or class of assets and may cause the Fund's NAV to be volatile.

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may have limited marketability or be subject to restrictions on sale, and may be difficult to sell at favorable times or prices. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund.

Loan Interests Risk
Unlike publicly traded common stocks which trade on national exchanges, there is no central place or exchange for loans to trade. Loans trade in an over-the-counter market, and confirmation and settlement, which are effected through standardized procedures and documentation, may take significantly longer than seven days to complete. Extended trade settlement periods may, in unusual market conditions with a high volume of shareholder redemptions, present a risk to shareholders regarding the Fund's ability to pay redemption proceeds within the allowable time periods stated in its prospectus. The secondary market for floating rate loans also may be subject to irregular trading activity and wide bid/ask spreads. The lack of an active trading market for certain floating rate loans may impair the ability of the Fund to sell its loan interests at a time when it may otherwise be desirable to do so or may require the Fund to sell them at prices that are less than what the Fund regards as their fair market value and may make it difficult to value such loans. Interests in loans made to finance highly leveraged companies or transactions, such as corporate acquisitions, may be especially vulnerable to adverse changes in economic or market conditions. When the Fund's loan interest is a participation, the Fund is subject to the risk that the party selling the participation interest will not remit the Fund's pro rata share of loan payments to the Fund and the Fund may have less control over the exercise of remedies than the party selling the participation interest.

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 the lack of liquidity or other adverse credit market conditions may hamper the Fund's ability to purchase and sell the debt securities. 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. Turbulence in financial markets and reduced liquidity in credit, fixed-income, or equity markets may negatively affect many issuers worldwide which could adversely affect the Fund.

Market Timing Risk
Frequent trading by Fund shareholders poses risks to other shareholders in that Fund, including (i) the dilution of the Fund's NAV, (ii) an increase in the Fund's expenses, and (iii) interference with the portfolio manager's ability to execute efficient investment strategies. Because of specific securities in which the Fund may invest, it could be subject to the risk of market timing activities by shareholders.

Municipal Securities Risk
Municipal securities could be adversely affected by adverse political and legislative changes. Changes in the financial condition of a municipality may affect the ability of a municipal issuer to make interest and principal payments on a security as they become due. Changes in interest rates and market conditions may directly impact the liquidity and valuation of municipal securities, which may affect the yield and value of the Fund's municipal securities investments. A downgrade in the issuer's or security's credit rating can reduce the market value of the security.

Other Investment Companies Risk
The Fund may invest in shares of other registered investment companies, including exchange-traded funds ("ETFs"). To the extent that the Fund invests in shares of other registered investment companies, the Fund will indirectly bear the 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. For example, to the extent the Fund invests in ETFs that invest in equity securities, fixed income securities and/or foreign securities, or track an index, the Fund is subject to the risks associated with investing in such securities or the index fluctuations. Because ETFs are listed on an exchange, they may be subject to trading halts and may trade at a discount or premium to their NAV.

Prepayment and Extension Risk
Prepayment risk is the risk that the principal amount of the underlying collateral may be repaid prior to the bond's maturity date. Due to a decline in interest rates or excess cash flow, a debt security may be called or otherwise prepaid before maturity. If this occurs, no additional interest will be paid on the investment and the Fund may have to invest at a lower rate, may not benefit from an increase in value that may result from declining interest rates, and may lose any premium it paid to acquire the security. Variable and floating rate securities may be less sensitive to prepayment risk. Extension risk is the risk that a decrease in prepayments may, as a result of higher interest rates or other factors, result in the extension of a security's effective maturity, heighten interest rate risk and increase the potential for a decline in price.

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-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 short sales and investments in derivatives, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the position or transaction, which cannot be sold while the position they are covering is outstanding, unless they are replaced with other assets of equal value.

Unrated Securities Risk
Investing in unrated securities involves the risk that the sub-advisor may not accurately evaluate the security's comparative credit rating. To the extent that the Fund invests in unrated securities, the Fund's success in achieving its investment objective may depend more heavily on the sub-advisors' credit analysis than if the Fund invested exclusively in rated securities.

U.S. Government Securities Risk 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 entities are also subject to credit risk, interest rate risk and market risk.

Valuation Risk
The Fund may value certain assets at a price different from the price at which they can be sold. This risk may be especially pronounced for investments, such as certain derivatives, which may be illiquid or which may become illiquid.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example - (American Beacon The London Company Income Equity Fund℠) - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	685	916	1,167	1,881
Class C	292	594	1,021	2,212
Class Y	86	268	466	1,037
Institutional Class	82	247	426	946
Investor Class	107	334	579	1,283

Assuming no redemption of shares:

Expense Example, No Redemption - (American Beacon The London Company Income Equity Fund℠)	1 Year	3 Years	5 Years	10 Years
Class C | USD ($)	192	594	1,021	2,212

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover 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 15% of the average value of its portfolio.

Principal Investment Strategies

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 and equity-related investments. The Fund's investments in equity and equity-related investments include U.S. common stocks, preferred stocks, American Depositary Receipts ("ADRs"), U.S. dollar-denominated foreign stocks traded on U.S. exchanges, securities convertible into or exchangeable for common stock, real estate investment trusts ("REITs"), and income trusts. The Fund may also invest up to 20% of its net assets in fixed income instruments, primarily including trust preferred securities and U.S. Government securities. The Fund may invest in issuers of any market capitalization and will typically hold 30 to 40 issuers in the Fund.

The Fund's investment sub-advisor, The London Company of Virginia, LLC ("The London Company"), emphasizes investments in profitable, financially stable, core companies that focus on generating high dividend income, are run by shareholder-oriented management, and trade at reasonable valuations. The London Company also seeks companies with high return on capital, consistent free cash flow generation, predictability and stability. The London Company employs an investment process with bottom up, fundamental analysis and follows a strict sell discipline.

On a short-term basis, the Fund may invest cash balances in other investment companies including money market funds, and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs.

Principal Risks

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:

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

Dividend Risk
An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks.

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, real estate investment trusts ("REITs"), ADRs, U.S. dollar-denominated foreign stocks traded on U.S. exchanges and income trusts. Such investments may expose the Fund to additional risks. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. 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. Preferred stocks stocks may be less liquid than common stocks and, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred stocks generally are payable at the discretion of an issuer and after required payments to bond holders. 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 ADRs and U.S. dollar-denominated foreign stocks traded on U.S. exchange are subject to certain of the risks associated with investing directly in foreign securities. 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. Income trusts are subject to credit risk, interest rate risk and dividend risk. Income trusts are subject to credit risk, interest rate risk and dividend risk. Income trusts, which hold income producing assets and pass the income on to security holders, share many of the risks inherent in stock ownership and may lack diversification.

Focused Holdings Risk
Because the Fund may have a focused portfolio of fewer companies, the increase or decrease of the value of a single investment may have a greater impact on the Fund's NAV and total return when compared to other diversified funds.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity and greater volatility, (4) lack of uniform accounting, auditing and financial reporting standards, (5) increased price volatility, (6) less government regulation and supervision of foreign stock exchanges, brokers and listed companies; and (7) delays in transaction settlement in some foreign markets.

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. 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 (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).

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. As of the date of this Prospectus, interest rates are near historic lows, but may rise substantially and/or rapidly, potentially resulting in substantial losses to the Fund. Generally, the value of investments with interest rate risk, such as fixed income securities, will move in the opposite direction to movements in interest rates. The prices of fixed income securities or derivatives are also affected by their duration. Fixed income securities or derivatives with longer duration generally have greater sensitivity to changes in interest rates. For example, if a bond has a duration of eight years, a 1% increase in interest rates could be expected to result in a 8% decrease in the value of the bond. An increase in interest rates can impact markets broadly as well. For example, some investors buy securities and derivatives with borrowed money; an increase in interest rates can cause a decline in those markets.

Investment Risk
An investment in the Fund is not a deposit with 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, and/or the return generated by, 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 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. The Fund's fixed-income investments are subject to the risk that the lack of liquidity or other adverse credit market conditions may hamper the Fund's ability to purchase and sell the debt securities. 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. Turbulence in financial markets and reduced liquidity in credit, fixed-income, or equity markets may negatively affect many issuers worldwide which could adversely affect the Fund.

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, the Fund will indirectly bear the 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. For example, money market funds are subject to interest rate risk, credit risk, and market risk.

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-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 the purchase and sale of futures contracts, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the position or transaction, which cannot be sold while the position they are covering is outstanding, unless they are replaced with other assets 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.

Trust Preferred Securities Risk
Trust preferred securities are subject to market risk and credit risk. Holders of the trust preferred securities have limited voting rights to control the activities of the trust and no voting rights with respect to the parent company.

U.S. Government Securities Risk 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 entities are also subject to credit risk, interest rate risk and market risk.
