These types of securities are commonly referred to as “high yield bonds” or “junk bonds.” The Fund seeks capital appreciation by investing in issues whose relative value is expected to increase over time. The Fund has no limitations regarding the maturities of the debt securities it can buy or the market capitalization of the issuers of those securities.</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’s assets are currently allocated among the Manager and two investment sub-advisors.</p><p>The Fund seeks its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a diversified portfolio of domestic and foreign high yield bonds. High yield issuers are generally those which have below investment grade ratings because they are relatively small in size, relatively young in years, relatively leveraged financially (perhaps borrowing heavily to finance expansion or due to a leveraged buyout), or formerly “blue chip” companies that have encountered some financial difficulties.</p><p>In selecting investments, the Fund’s sub-advisors utilize a bottom-up and research-driven investment process that relies heavily on internal research and fundamental credit analysis. The investment philosophy of each sub-advisor concentrates on identification of relative value and downside protection.</p><p>To a lesser extent, the Fund may invest in other securities, including investment grade securities, foreign securities, common and preferred stocks, convertible securities, warrants and rights, in keeping with the Fund’s overall investment objective.</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>Interest Rate Risk</b></p><p>The Fund is subject to the risk that the market value of the bonds it holds will decline due to rising interest rates. When interest rates rise, the prices of most bonds go down. The price of a bond is also affected by its maturity. Bonds with longer maturities generally have greater sensitivity to changes in interest rates.</p><p><b>Credit Risk</b></p><p>The Fund is subject to the risk that the issuer of a bond will fail to make timely payment of interest or principal. A decline in an issuer’s credit rating can cause the price of its bonds to go down. Since the Fund invests in lower-quality debt securities considered speculative in nature, this risk will be substantial.</p><p><b>High Yield Securities Risk</b></p><p>Investing in high yield, non-investment grade bonds generally involves significantly greater risks of loss of your money than an investment in investment grade bonds. Compared with issuers of investment grade bonds, high yield bonds are more likely to encounter financial difficulties and to be materially affected by these difficulties. Rising interest rates may compound these difficulties and reduce an issuer’s ability to repay principal and interest obligations. Issuers of lower-rated securities also have a greater risk of default or bankruptcy.</p><p><b>Prepayment and Extension Risk</b></p><p>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.</p><p><b>Market Risk</b></p><p>The Fund is subject to market risks that can affect the value of its shares. These risks include political, regulatory, market and economic developments, including developments that impact specific economic sectors, industries or segments of the market. For example, market risk involves the possibility that the value of the Fund’s investments will decline due to drops in the overall high yield bond market. Changes in the economic climate, investor perceptions, and stock market volatility can cause the prices of the Fund’s investments to decline, regardless of the financial conditions of the issuers held by the Fund. From time to time, certain securities held by the Fund may have limited marketability or contractual limitations on their resale and may be difficult to value and sell at favorable times or prices. If the Fund is forced to sell securities to meet redemption requests, the Fund may have to sell those securities at a loss.</p><p><b>Equity Securities Risk</b></p><p>Equity securities generally are subject to market risk. The Fund’s investments in equity securities may include common and preferred stocks, convertible securities and rights and warrants. Investing in such securities may expose the Fund to additional risks.</p><p>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 rights and warrants may be more speculative than certain other types of investments because rights and warrants do not carry with them dividend or voting rights with respect to the underlying securities, or any rights in the assets of the issuer. In addition, the value of a right or a warrant does not necessarily change with the value of the underlying securities, and a right or a warrant ceases to have value if it is not exercised prior to its expiration date.</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>Market Timing Risk</b></p><p>Because the Fund invests in high yield bonds that may lack market liquidity, it is subject to the risk of market timing activities. The limited trading activity of some high yield bonds may result in market prices that do not reflect the true market value of these illiquid securities. In such instances, the Fund may fair value illiquid 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’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>Hedging Risk</b></p><p>Gains or losses from positions in hedging instruments may be much greater than the instrument’s original cost. The counterparty may be unable to honor its financial obligation to the Fund. In addition, a sub-advisor may be unable to close the transaction at the time it would like or at the price it believes the security is currently worth.</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’s underperformance compared to other funds with similar investment objectives.</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>High Portfolio Turnover Risk </b></p><p>Portfolio turnover is a measure of a Fund’s trading activity over a one-year period. A portfolio turnover rate of 100% would indicate that a Fund sold and replaced the entire value of its securities holdings during the period. High portfolio turnover could increase a Fund’s transaction costs and possibly have a negative impact on performance. Frequent trading by a Fund could also result in increased short-term capital gain distributions to shareholders, which are taxable as ordinary income.</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.

However, because the Institutional Class had lower expenses, its performance was better than the newer share classes would have realized in the same period.

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. This occurs when a capital loss is realized upon redemption, resulting in a tax deduction that benefits the shareholder. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. 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.</i>128Risk/Return Summary - American Beacon High Yield Bond Fund (Class A, C, Institutional, Y and Investor) (American Beacon High Yield Bond Fund, Class A, C, Institutional, Y and Investor)UnKnownUnKnownUnKnownUnKnownfalsetrue
