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 Treasury Inflation Protected Securities Fund℠) (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	562	757	967	1,571
Class C	271	532	917	1,997
Class Y	62	200	349	784
Institutional Class	31	118	214	495
Investor Class	70	247	438	991

Assuming no redemption of shares:

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 102% 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 inflation-indexed debt securities issued by the U.S. Treasury Department and backed by the full faith and credit of the U.S. Government. Under normal circumstances, the Fund's dollar-weighted average maturity is expected to be between three and twenty years.

Inflation-indexed securities, also known as inflation-protected securities, are fixed-income instruments structured such that their interest and/or principal payments are adjusted in order to provide a total return exceeding inflation over the long term. 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.

NISA Investment Advisors, L.L.C. uses strategic (top-down) and tactical (bottom-up) analyses to determine a strategy whose goal is to outperform the Fund's benchmark. Standish Mellon Asset Management Company LLC's investment process combines top down cyclical macroeconomic analysis with bottom-up relative value analysis. Standish Mellon Asset Management Company LLC's top-down research contributes 60% – 70% of the value added and drives duration and yield curve strategies. The remaining 30% – 40% of the value added is generated by Standish Mellon Asset Management Company LLC's bottom-up issue selection focusing on the issue's theoretical fair value, seasonality impacts and supply/demand. The sub-advisors actively manage the Fund's portfolio and the Fund may, at times, engage in short-term trading.

The Fund may also invest cash balances in other investment companies, including money market funds.

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, including a U.S. Government agency, will fail to make timely payment of interest or principal or otherwise honor its obligations or default completely.

Deflation Risk
In a period of sustained deflation, the inflation-indexed securities held by the Fund may not pay any income. Although the U.S. Treasury guarantees to pay at least the original face value of any inflation-indexed securities it issues, other issuers may not offer the same guarantee. As a result, the Fund may suffer a loss during periods of sustained deflation.

Government Securities Risk
U.S. Government securities and securities of government sponsored enterprises are subject to credit risk, interest rate risk and market risk. A security backed by the U.S. Treasury or the full faith and credit of the United States is only 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. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest and principal. 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. There is no assurance that the U.S. Government will provide financial support if these organizations do not have the funds to meet future payment obligations.

High Portfolio Turnover Risk
Portfolio turnover is a measure of the Fund's trading activity over a one year period. A portfolio turnover rate of 100% would indicate that the Fund sold and replaced the entire value of its securities holdings during the period. High portfolio turnover could increase the Fund's transaction costs and possibly have a negative impact on performance.

Income Risk
Because the interest and/or principal payments on an inflation-indexed security are adjusted periodically for changes in inflation, the income distributed by the Fund may be irregular. To achieve a total return greater than the rate of inflation over the long term, the portion of the Fund's distributions attributable to inflation adjustments must be reinvested in additional Fund shares.

Interest Rate Risk
The Fund is subject to the risk that the market value of fixed income securities it holds will decline due to changes in 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 are also affected by their durations. Fixed income securities 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 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.

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. Turbulence in the financial markets and reduced liquidity in credit and fixed income markets may lead to periods of volatility, unusual liquidity issues and, in some cases, credit downgrades and increased likelihood of default. 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 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.

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.

Fund Performance

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 below show the performance of the Fund's Investor Class shares for all periods. The Fund began offering Institutional Class shares on June 30, 2004, Investor Class shares on March 1, 2009, Y Class shares on March 1, 2010, A Class shares on May 17, 2010 and C Class shares on September 1, 2010. The performance of the Investor Class shares shown in the chart and table below represents the returns of the Institutional Class shares from June 30, 2004 to March 2, 2009 and the performance of the Investor Class shares from March 2, 2009 to December 31, 2014. Performance for the Y Class, A Class and C Class shares represents: (1) the returns achieved by the Institutional Class shares from June 30, 2004 to March 2, 2009, (2) the returns achieved by the Investor Class shares from March 2, 2009 to the inception date of the Y Class, A Class and C Class shares, respectively; and (3) the returns achieved by each such share class through December 31, 2014. 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, which would affect performance. You may obtain updated performance information on the Funds' 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 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

[1] A contingent deferred sales charge (''CDSC'') of 0.50% will be charged on certain purchases of $1,000,000 or more of A Class shares that are redeemed in whole or part within 18 months of purchase.

[1] The Manager has contractually agreed to waive fees and/or reimburse expenses of the Fund's A Class, C Class, Y Class, and Investor Class shares, as applicable, through April 30, 2016 to the extent that Total Annual Fund Operating Expenses exceed 0.90% for the A Class, 1.68% for the C Class, 0.61% for the Y Class, and 0.69% for the Investor Class (excluding taxes, interest, brokerage commissions, acquired fund fees and expenses, securities lending fees, litigation, and other extraordinary expenses). The contractual expense reimbursement can be changed only with the approval of a majority of the Fund's Board of Trustees. The Manager can be reimbursed by the Fund for any contractual fee waivers or expense reimbursements if reimbursement to the Manager (a) occurs within three years after the Manager's own waiver or reimbursement and (b) does not cause the Total Annual Fund Operating Expenses of a class to exceed the contractual percentage limit in effect at the time of the waiver/reimbursement.

[2] The Manager has contractually agreed to waive fees and/or reimburse expenses of the Fund's Institutional Class through April 30, 2016 in an amount equal to 0.10% of the average daily net assets (excluding taxes, interest, brokerage commissions, acquired fund fees and expenses, securities lending fees, litigation, and other extraordinary expenses). The administrative services fee reduction can be changed only by approval of the Fund's Board of Trustees. The Manager can be reimbursed by the Fund for any contractual or voluntary fee reductions or expense reimbursements if reimbursement to the Manager (a) occurs within three years after the Manager's own reduction or reimbursement and (b) does not cause the Expense Reduction and Reimbursement of a class to exceed the percentage limit contractually agreed.

[1] The fee table has been restated with respect to the Fund's A Class and C Class Shares to reflect a reduction in the administrative services fee effective July 1, 2014.
