The Fund will primarily invest in countries comprising the Morgan Stanley Capital International Europe Australasia Far East Index ("MSCI EAFE Index"). The MSCI EAFE Index is comprised of equity securities of companies from various industrial sectors whose primary trading markets are located outside the United States. Companies included in the MSCI EAFE Index are selected from among the larger capitalization companies in these markets. The Fund may invest in companies of all market capitalizations. The Fund may use futures contracts and foreign currency forward contracts as a hedge against foreign currency fluctuations.</p><p>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 minimizing volatility and downside risk. The Fund&#8217;s assets are currently allocated among four investment sub-advisors.</p><p>The sub-advisors select stocks that, in their opinion, have most or all of the following characteristics (relative to that stock&#8217;s country, sector or industry):</p><p>above-average return on equity or earnings growth potential, </p><p> below-average price to earnings or price to cash flow ratio, </p><p>below-average price to book value ratio, and</p><p>above-average dividend yields.</p><p>The sub-advisors may consider potential changes in currency exchange rates when choosing stocks. 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 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. A sub-advisor may trade forward foreign currency contracts or currency futures in an attempt to reduce the Fund&#8217;s risk exposure to adverse fluctuations in currency exchange rates.</p><p>The Fund may lend its securities to broker-dealers and other institutions to earn additional income.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

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:</p><p><b>Market Risk</b></p><p>Since this Fund invests most of its assets in stocks, it is subject to stock market risk. Market risk involves the possibility that the value of the Fund&#8217;s investments in stocks of a particular country will vary from day to day in response to the activities of individual companies, as well as general market, regulatory, political and economic conditions of that country. From time to time, certain securities held by the Fund may have limited marketability and may be difficult to sell at favorable times or prices. If the Fund is forced to sell such securities to meet redemption requests or other cash needs, the Fund may have to sell them at a loss.</p><p><b>Equity Securities Risk</b></p><p>Equity securities generally are subject to market risk. The Fund&#8217;s investments in equity securities include common stocks and securities convertible into common stocks. Investing in such securities may expose the Fund to additional risk. Common stock generally is subordinate to preferred stock, convertible securities and fixed income securities upon the liquidation or bankruptcy of the issuing company. In addition, convertible securities are subject to risk that the credit standing of the issuer may have an effect on the security&#8217;s investment value.</p><p><b>Foreign Investing Risk</b></p><p>Oversees investing caries potential risks not associated with domestic 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.</p><p><b>Value Stocks Risk</b></p><p>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&#8217;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.</p><p><b>Market Timing Risk</b></p><p>Because the Fund invests in foreign securities, it is particularly subject to the risk of market timing activities. The Fund generally prices foreign securities using their closing prices from the foreign markets in which they trade, typically prior to the Fund&#8217;s determination of its net asset value. These prices may be affected by events that occur after the close of a foreign market but before the Fund prices its shares. In such instances, the Fund may fair value foreign securities. However, some investors may engage in frequent short-term trading in the Fund to take advantage of any price differentials that may be reflected in the net asset value of the Fund&#8217;s shares. There is no assurance that fair valuation of securities can reduce or eliminate market timing. While the Manager monitors trading in Fund shares, there is no guarantee that it can detect all market timing activities.</p><p><b>Futures Contracts and Foreign Currency Forward Contracts Risk</b></p><p>Futures contracts and foreign currency forward contracts are derivative instruments pursuant to which a sub-advisor may enter into a contract with a counterparty to pay 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 they invested directly in the securities underlying those derivatives. Futures contracts may experience potentially dramatic price changes (losses) and imperfect correlations between the price of the contract and the underlying security, index or currency 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.</p><p><b>Securities Selection Risk</b></p><p>Securities selected by a sub-advisor for the Fund may not perform to expectations. This could result in the Fund&#8217;s underperformance compared to other funds with similar investment objectives.</p><p><b>Securities Lending Risk</b></p><p>To the extent the Fund lends its securities, it may be subject to the following risk. Borrowers of the Fund&#8217;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&#8217;s ability to vote proxies or to settle transactions.</p><p><b>Investment Risk</b></p><p>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.</p><p><b>Market Events</b></p><p>Turbulence in financial markets and reduced liquidity in equity, credit and fixed-income markets may negatively affect many issuers worldwide which may have an adverse effect on the Fund.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The table shows how the Fund&#8217;s performance compares to a broad-based market index and the Lipper International Funds Index, a composite of mutual funds comparable to the Fund.</p><p>The chart and the table below show the performance of the Fund&#8217;s Institutional Class shares for all periods. The Fund began offering Advisor Class shares on May 1, 2003, Retirement Class Shares on May 1, 2009, Y Class shares on August 3, 2009, A Class shares on May 17, 2010 and C Class shares on September 1, 2010. In the table below, the performance of the Investor Class is shown for the Advisor Class, A Class and C Class shares and the performance of the Institutional Class is shown for Y Class shares prior to the dates that such newer share classes were first offered. For Retirement Class shares, performance results before May 1, 2003 are for Investor Class shares and performance results from May 1, 2003 through May 1, 2009 are for Advisor Class shares. 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, because the older classes had lower expenses, their performance was better than the newer classes would have realized in the same period. You may obtain updated performance information on the Fund&#8217;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.</p><p>Sales charges are not reflected in the bar chart and table below.
