This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales discounts if you and your eligible family members invest, or agree to invest in the future, at least $50,000 in all classes of the American Beacon Funds on an aggregated basis. More information about these and other discounts is available from your financial professional and in "Choosing Your Share Class" on page  38 of the Prospectus and "Additional Purchase and Sale Information for A Class Shares" on page  45  of the Statement of Additional Information ("SAI"). With respect to purchases of shares through specific intermediaries, you may find additional information regarding sales charge discounts and waivers in Appendix A to the Fund's Prospectus entitled "Intermediary Sales Charge Discounts, Waivers and Other Information."

Shareholder Fees (fees paid directly from your investment)

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 this Example reflects the fee waiver/expense reimbursement arrangement for each share class through April 30, 2027.  C Class shares automatically convert to A Class shares 8 years after purchase, if the conversion is available through your financial intermediary. This Example reflects your costs as though C Class shares were held for the full 10-year period. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

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. Portfolio turnover is based on the lesser of long-term purchases or sales divided by the average long-term fair value during a period. The Fund did not invest in any long-term securities during the most recent fiscal year. As a result, the Fund's portfolio turnover rate for the Fund's most recent fiscal year is not provided.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by implementing a quantitative trading strategy and systematic investment process designed to capitalize on price trends (up and/or down) in a broad range of around 120 global markets by utilizing derivative instruments to seek exposure to stock indices, bonds, currencies, and interest rates. As the owner of a "long" position in a derivative instrument, the Fund may benefit from an increase in the price of the underlying investment and, as the owner of a "short" position, the Fund may benefit from a decrease in the price of the underlying investment.

The Fund invests primarily in derivatives, including futures contracts (such as equity index futures, bond index futures, interest rate futures, treasury futures, and non-U.S. currency futures), and foreign currency forward contracts, including non-deliverable forwards ("NDFs"). The Fund also may invest in swaps, and other types of derivative instruments linked to stock indices, currencies, bonds, interest rates and commodity instruments. The Fund expects that, under normal market conditions, the notional value of its derivatives exposure generally will exceed that of its net assets. In order to meet collateral requirements in connection with the Fund's use of derivatives, which may be used for hedging purposes or for exposure to a market, the Fund may hold significant amounts of (1) U.S. government securities, including U.S. Treasury securities, (2) other foreign developed market sovereign short-term bonds issued by countries such as France, Germany, Japan and other developed countries, (3) short-term investments, (4) cash and (5) time deposits. The Fund may obtain market exposure by investing in an affiliated exchange-traded fund ("ETF") with respect to which the Manager receives a management fee and the sub-advisor receives an investment advisory fee. Additionally, the Fund may invest in bonds and zero coupon securities,  U.S. and non-U.S. currencies and instruments denominated in non-U.S. currencies. The Fund's investments are generally made without restriction as to issuer market capitalization, country, currency, or maturity. The Fund may invest in issuers in the U.S. and foreign developed and emerging  markets.

The Fund seeks to gain exposure to the commodity futures markets by investing up to 25% of its total assets in a wholly-owned subsidiary, which is organized under the laws of the Cayman Islands (the "Subsidiary"). Generally, the Subsidiary invests primarily in commodity futures, but it may also invest in financial futures and forwards and swap contracts, fixed income securities, pooled investment vehicles, including open-end investment companies, and other investments intended to serve as margin or collateral for the Subsidiary's derivative positions. The Fund invests in the Subsidiary in order to gain exposure to the commodities markets within the limitations of the federal tax law, rules and regulations that apply to "regulated investment companies." Unlike the Fund, the Subsidiary may invest without limitation in commodity-linked derivatives, however, the Subsidiary and the Fund, in the aggregate, comply with applicable requirements for derivatives transactions set forth in Rule 18f-4 under the Investment Company Act of 1940, as amended (the "Investment Company Act"). In addition, the Fund and the Subsidiary comply with the same fundamental investment restrictions on an aggregate basis, and the Subsidiary follows the same compliance policies and procedures as the Fund to the extent those restrictions, policies and procedures are applicable to the investment activities of the Subsidiary. Unlike the Fund, the Subsidiary does not, and will not, seek to qualify as a "regulated investment company" under Subchapter M of Chapter 1 of Subtitle A of the Internal Revenue Code of 1986, as amended ("Subchapter M"). The Fund is the sole shareholder of the Subsidiary and does not expect shares of the Subsidiary to be offered or sold to other investors.

The sub-advisor employs computerized processes to identify investment opportunities across a wide range of markets around the world. Investment decisions are  executed via the sub-advisor's proprietary execution strategy.  The investment decision  process is quantitative and primarily directional in nature, meaning that investment decisions are driven by mathematical models based on market trends and other historical relationships. It is underpinned by risk control, ongoing research, diversification and the quest for efficiency. The Fund's holdings may be frequently adjusted to reflect the sub-advisor's assessment of changing risks, which could result in high portfolio turnover. The sub-advisor's strategy is designed to provide an excess return with a stable level of volatility regardless of market conditions. The sub-advisor seeks to do this by using systematic algorithms (a mathematical model) to scale positions based on the net asset value ("NAV") of the Fund. The algorithm measures the degree of volatility in a particular market. As volatilities increase, the algorithm will look to reduce exposure. Conversely, it will increase exposure, subject to risk limits, if the market is calm and volatilities are decreasing. This technique is called `volatility scaling' and can be applied at various levels to achieve a balanced risk exposure through time, and across different asset classes. Volatility scaling aims to achieve a certain target level of volatility which is stable through time. The Fund has set an annualized volatility target of 10% of its NAV. Volatility is defined as the annualized standard deviation of returns. It is important to note that both the short and long term realized volatility of the Fund can and will differ from the targeted volatility and can be dependent on prevailing market conditions.  

The cornerstone of the sub-advisor's investment philosophy is that the financial markets exhibit trends and other inefficiencies. Trends are a manifestation of serial correlation in financial markets - the phenomenon whereby past price movements influence price behavior. Although price trends vary in their intensity, duration and frequency they typically recur across sectors and markets. Trends are an attractive focus for active trading styles applied across a range of global markets. In implementing its investment program, the Fund may hold significant cash positions from time to time. The Fund may have significant exposure to issuers located in, or with economic ties to, Europe and Japan. However, as the sector and geographic composition of the Fund's portfolio changes over time, the Fund's exposure to Europe and/or Japan may decline, and the Fund's exposure to other geographic areas may increase.

The Fund is non-diversified, which means that it is not limited to a percentage of assets that it may invest in any one issuer.

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 listed below are presented in alphabetical order and not in order of importance or potential exposure. Among other matters, this presentation is intended to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a "principal risk" of investing in the Fund, regardless of the order in which it appears. The principal risks of the Subsidiary are listed in this section of the Prospectus as principal risks of the Fund.  

Allocation Risk
The allocations among strategies, asset classes and market exposures may be less than optimal and may adversely affect the Fund's performance. There can be no assurance, particularly during periods of market disruption and stress, that judgments about allocations will be correct. The Fund's allocations may be invested in strategies, asset classes and market exposures during a period when such strategies, asset classes and market exposures underperform.

Asset Selection Risk
Assets selected for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objective.

Commodities Risk
The Fund's investments in commodity-linked derivative instruments may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, commodity price volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as changes in supply and demand, resource availability, speculation in the commodities markets, drought, floods, weather, livestock disease, pandemics, embargoes, tariffs, war, acts of terrorism and international economic, political and regulatory developments. The Fund may invest significantly in a particular sector of the commodities market (such as oil, metal or agricultural products). As a result, the Fund may be more susceptible to risks associated with those sectors. No active trading market may exist for certain commodities investments. The Fund's investments in commodity-related instruments may lead to losses in excess of the Fund's investment in such products, as some commodity-linked derivatives can have the potential for unlimited losses. Such losses can significantly and adversely affect the net asset value ("NAV") per share of the Fund and, consequently, a shareholder's interest in the Fund. Because the Fund's performance is linked to the performance of potentially volatile commodities, investors should be willing to assume the risks of significant fluctuations in the value of the Fund's shares.

Counterparty Risk
The Fund is subject to the risk that a party or participant to a transaction, such as a broker or a 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, guarantor or insurer of an obligation, or the counterparty to a transaction, may fail, or become less able or unwilling, to make timely payment of interest or principal or otherwise honor its obligations or default completely. Changes in the actual or perceived creditworthiness of an issuer, or a downgrade or default affecting any of the Fund's securities, could affect the Fund's performance. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

Crowding/Convergence Risk
There is significant competition among quantitatively-focused managers, and the ability of the sub-advisor to outperform other funds is dependent on its ability to employ models that are simultaneously profitable and differentiated from those employed by other managers. To the extent that the sub-advisor is not able to develop sufficiently differentiated models, the Fund's investment objective may not be met, irrespective of whether the models are profitable in an absolute sense.

Currency Risk
The Fund may have exposure to foreign currencies. Foreign currencies may fluctuate significantly over short periods of time, may be affected unpredictably by intervention, or the failure to intervene, of the  U.S. or foreign governments or central banks, and may be affected by currency controls or political developments in the U.S. or abroad. Foreign currencies may also decline in value relative to the U.S. dollar and other currencies and thereby affect the Fund's investments.

Cybersecurity and Operational Risk
Operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents may negatively impact the Fund, its service providers and third-party fund distribution platforms, including the ability of shareholders to transact in the Fund's shares, and result in financial losses. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, or cause the Fund or its service providers, as well as securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. The Fund cannot control the cybersecurity and operational plans and systems of its service providers, its counterparties or the issuers of securities in which the Fund invests. The issuers of the Fund's investments are likely to be dependent on computers for their operations and require ready access to their data and the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of the Fund's investments, leading to significant loss of value.

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 or other instruments 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.   The use of derivatives may also increase any adverse effects resulting from the underperformance of strategies, asset classes and market exposures to which the Fund has allocated its assets. Derivatives may at times be highly illiquid, and the Fund may not be able to close out or sell a derivative at a particular time or at an anticipated price. Certain derivatives may be difficult to value, and valuation may be more difficult in times of market turmoil. Derivatives may also be more volatile than other types of investments. Derivative investments can increase portfolio turnover and transaction costs. Derivatives also are subject to counterparty risk  and credit risk. As a result, the Fund may not recover 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. Derivatives transactions requiring the Fund to post collateral may expose the Fund to greater losses in the event of a default by a counterparty.  There may be imperfect correlation between the behavior of a derivative and that of the reference instrument underlying the derivative. An abrupt change in the price of a reference instrument could render a derivative worthless. Derivatives may involve risks different from, and possibly greater than, the risks associated with investing directly in the reference instrument. The Fund may buy or sell derivatives not traded on an exchange, which may be subject to heightened  counterparty, liquidity and valuation risks. Suitable derivatives may not be available in all circumstances, and there can be no assurance that the Fund will use derivatives to reduce exposure to other risks when that might have been beneficial. Ongoing changes to the regulation of derivatives and

American Beacon AHL Managed Futures Strategy Fund - Summary Prospectus3

changes in the regulation of funds using derivative instruments could limit the Fund's ability to pursue its investment strategies. New regulation of derivatives may make them more costly, or may otherwise adversely affect their liquidity, value or performance.  In addition, the Fund's investments in derivatives are subject to the following risks:

Emerging Markets Risk
When investing in emerging markets, the risks of investing in foreign securities 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 or economic 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 resulting in increased volatility and limited liquidity for emerging market securities; trading suspensions and other restrictions on investment; delays and disruptions in securities clearing and settlement procedures; and significant limitations on investor rights and recourse. The governments of emerging market countries may also be more unstable and more likely to impose capital controls, nationalize a company or industry, place restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, intervene in the financial markets, and/or impose burdensome taxes that could adversely affect security prices. In addition, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing, financial reporting and recordkeeping standards and requirements comparable to those to which U.S. companies are subject.

Foreign Exposure Risk
Exposure to  non-U.S. issuers carries potential risks not associated with exposure to U.S. issuers. Such risks may include, but are not limited to: (1) political and financial instability, (2) less liquidity, (3) greater volatility, and (4) different government regulation The Fund's exposure to a foreign issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with that country, including tariffs, trade disputes and sanctions. Global economic and financial markets have become increasingly interconnected and conditions (including recent volatility, terrorism, war and political instability) and events (including natural disasters) in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

Geographic Concentration Risk
From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in the securities of issuers located in, or with significant economic ties to, a single country or geographic region, which could increase the risk that economic, market, political, business, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund's performance. Investing in such a manner could cause the Fund's performance to be more volatile than the performance of more geographically diverse funds. A decline in the economies or financial markets of one country or region may adversely affect the economies or financial markets of another.

4American Beacon AHL Managed Futures Strategy Fund - Summary Prospectus

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. In addition, hedges, even when successful in mitigating risk, may not prevent the Fund from experiencing losses on its investments. Hedging instruments may also reduce or eliminate gains that may otherwise have been available had the Fund not used the hedging instruments.

High Portfolio Turnover Risk
Portfolio turnover is a measure of the Fund's trading activity over a one-year period. The Fund may engage in active and frequent trading, which could increase the Fund's transaction costs, have a negative impact on performance, and generate higher capital gain distributions to shareholders than if the Fund had lower portfolio turnover.

Interest Rate Risk
Generally, the value of investments with interest rate risk, such as fixed-income securities or derivatives, will move in the opposite direction as movements in interest rates. Factors including central bank monetary policy, rising inflation rates, and changes in general economic conditions may cause interest rates to rise, which could cause the value of the Fund's investments to decline. Interest rate increases, including significant or rapid increases, may result in a decline in the value of bonds or derivatives held by the Fund, make issuers less willing or able to make principal and interest payments on fixed-income investments when due, lead to heightened volatility in the fixed-income markets and adversely affect the liquidity of certain fixed-income investments, any of which may result in substantial losses to the Fund. When interest rates decline, issuers may prepay higher-yielding securities held by the Fund, resulting in the Fund reinvesting in securities with lower yields, which may cause a decline in its income. The prices of fixed-income securities or derivatives are also affected by their  durations. Fixed-income securities or derivatives with longer durations generally have greater sensitivity to changes in interest rates than those with shorter durations. Rising interest rates may cause the value of the Fund's investments with longer durations and terms to maturity to decline, which may adversely affect the value of the Fund. For example, if a bond has a duration of eight years, a 1% increase in interest rates could be expected to result in an 8% decrease in the value of the bond. Fluctuations in interest rates may also affect the liquidity of fixed-income securities and instruments held by the Fund.

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.

Leverage Risk
The Fund's use of derivative instruments and taking of short positions may have the economic effect of financial leverage. Financial leverage magnifies the Fund's exposure to the movements in prices of an asset or class of assets underlying a derivative instrument and may result 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 net asset value ("NAV") per share to be volatile. There can be no assurance that the Fund's use of leverage will be successful.

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may have limited marketability, be subject to restrictions on sale, be difficult or impossible to purchase or sell at favorable times or prices or become less liquid in response to market developments or adverse credit events that may affect issuers or guarantors of a security. An inability to sell a portfolio position can adversely affect the Fund's value or prevent the Fund from being able to take advantage of other investment opportunities. Market prices for such instruments may be volatile. During periods of substantial market volatility, an investment or even an entire market segment may become illiquid, sometimes abruptly, which can adversely affect the Fund's ability to limit losses. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund.  Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

Market Risk
The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect the Fund's performance. The financial markets generally move in cycles, with periods of rising prices followed by periods of declining prices. The value of your investment may reflect these fluctuations. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Even when certain securities prices have generally increased over time, there have been periods of price decreases during those times, resulting in losses for investors, which are likely to occur again in the future.

American Beacon AHL Managed Futures Strategy Fund - Summary Prospectus5

Geopolitical and other events, including war, terrorism, trade disputes, pandemics, public health crises, natural disasters, and  cybersecurity incidents, have led, and in the future may continue to lead, to general instability in world economies and markets and reduced liquidity in securities, which may negatively affect the value of your investment.

Policies established by the  U.S. government and/or Federal Reserve and economic and political circumstances within the U.S. and abroad, such as inflation, changes in interest rates, recessions, changes in government leadership, a government's inability to agree on a budget, high public debt, the threat or occurrence of a federal government shutdown and threats or the occurrence of a failure to increase the federal government's debt limit, which could result in a default on the government's obligations, may negatively affect investor and consumer confidence and may negatively impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Markets and market participants are increasingly reliant upon public and proprietary data and systems. Data or technology malfunctions and inaccuracies may disrupt markets and lead to negative consequences for market participants like the Fund.  

Market Direction Risk
Since the Fund will typically hold both long and short positions, an investment in the Fund will involve market risks associated with different types of investment decisions than those made for a typical "long only" fund. The Fund's results could suffer both when there is a general market advance and the Fund holds significant "short" positions, and when there is a general market decline and the Fund holds significant "long" positions.

Market Timing Risk
The Fund is subject to the risk of market timing activities by investors due to the nature of the Fund's investments, which requires the Fund, in certain instances, to fair value certain of its investments. 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 ("NAV") of the Fund's shares. Frequent trading by Fund shareholders poses risks to other shareholders in the Fund, including (i) the dilution of the Fund's NAV, (ii) an increase in the Fund's expenses, and (iii) interference with the ability to execute efficient investment strategies.

Model and Data/Programming Error Risk
The success of the sub-advisor's investment strategy depends largely on the effectiveness of its quantitative research models and investment programs. Models (including quantitative models), data, and investment programs are used to screen potential investments for the Fund. When models or data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks and programs may not react as expected to market events, resulting in losses for the Fund. Some of the models used by the sub-advisor are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. There is no assurance that the models are complete or accurate, or representative of future market cycles, nor will they always be beneficial to the Fund if they are accurate. Additionally, programs may become outdated or experience malfunctions which may not be identified by the sub-advisor and therefore may also result in losses to the Fund. These models and programs may negatively affect Fund performance for various other reasons, including human judgment, inaccuracy of historical data and non-quantitative factors (such as market or trading system dysfunctions, investor fear or overreaction). The use of artificial intelligence or other evolving or emerging technologies presents significant risks and may exacerbate the aforementioned risks.

Models and data are known to have errors, omissions, imperfections and malfunctions (collectively, "System Events"). The sub-advisor seeks to reduce the incidence and impact of System Events, to the extent feasible, through a combination of internal testing, simulation, real-time monitoring, and use of independent safeguards in the overall portfolio management process and often in the software code itself. Despite such testing, monitoring and independent safeguards, System Events will result in, among other things, the execution of unanticipated trades, the failure to execute anticipated trades, delays in the execution of anticipated trades, the failure to properly allocate trades, the failure to properly gather and organize available data, the failure to take certain hedging or risk reducing actions and/or the taking of actions which increase certain risk(s) - all of which may have materially adverse effects on the Fund. System Events in third-party provided data are generally entirely outside the control of the sub-advisor.

Non-Diversification Risk
The Fund is non-diversified, which means it may focus its investments in the securities of a comparatively small number of issuers. Investments in securities of a limited number of issuers exposes the Fund to greater market risk, price volatility and potential losses than if assets were diversified among the securities of a greater number of issuers.  

Obsolescence Risk
The sub-advisor is unlikely to be successful in the deployment of its quantitative, systematic, investment strategies unless the assumptions underlying the models are realistic and either remain realistic and relevant in the future or are adjusted to account for changes in the overall market environment. If such assumptions

6American Beacon AHL Managed Futures Strategy Fund - Summary Prospectus

are inaccurate or become inaccurate and are not promptly adjusted, it is likely that the models will not generate profitable trading signals. If and to the extent that the models do not reflect certain relevant factors, and the sub-advisor does not successfully address such omission through its testing and evaluation by modifying the models accordingly, major losses may result - all of which will be borne by the Fund. There can be no assurance as to the effects (positive or negative) of any changes including additions, modifications and removal of the models or investment strategies on the Fund's performance.  

Other Investment Companies Risk
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 those investment companies in addition to the Fund's direct fees and expenses. To the extent the Fund invests in other investment companies that invest in equity securities, fixed-income securities and/or foreign securities, or that track an index, the Fund is subject to the risks associated with the underlying investments held by the investment company or the index fluctuations to which the investment company is subject. The Fund will be subject to the risks associated with investments in those companies, including but not limited to the following:

Quantitative Strategy Risk
The success of the Fund's investment strategy may depend in part on the effectiveness of the  sub-advisor's quantitative tools for screening securities. These strategies may incorporate factors that are not predictive of a security's value. The quantitative tools may not react as expected to market events, resulting in losses for the Fund. Additionally, a previously successful strategy may become outdated or inaccurate, which may not be identified by the sub-advisor and therefore may also result in losses. The use of artificial intelligence or other evolving or emerging technologies presents significant risks and may exacerbate the aforementioned risks.

Redemption Risk
The Fund may experience periods of high levels of redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. Heavy redemptions could hurt the Fund's performance. The sale of assets to meet redemption requests may create net capital gains, which could cause the Fund to have to distribute substantial capital gains. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund. In addition, redemption risk is heightened during periods of declining or illiquid markets. A rise in interest rates or other market developments may cause investors to move out of fixed-income securities on a large scale. During periods of heavy redemptions, the Fund may borrow funds through the interfund credit facility or from a bank line of credit, which may increase costs.

Risk Management
Risk is an essential part of investing. No risk management program can eliminate the Fund's exposure to adverse events; at best, it can only reduce the possibility that the Fund will be affected by such events, and especially those risks that are not intrinsic to the Fund's investment program. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

Segregated Assets Risk
In connection with certain transactions that may give rise to future payment obligations, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the obligation. Segregated assets generally cannot be sold while the position they are covering is outstanding, unless they are replaced with other assets of equal value. The need to segregate cash or other liquid securities could limit the Fund's ability to pursue other opportunities as they arise.

Short Position Risk
The Fund will incur a loss as a result of a short position if the price of the instrument sold short increases in value between the date of the short sale and the date on which an offsetting position is purchased. Short positions may be considered speculative transactions and involve special risks, including greater reliance on the sub-advisor's ability to accurately anticipate the future value of a security or instrument. As there is potentially no limit on the amount that the security that the Fund is required to purchase may have appreciated, the Fund's losses are potentially unlimited in a short position transaction, particularly in cases where the Fund is unable to close out its short position. The Fund may invest the proceeds of a short sale and, therefore, be subject to the effect of leverage, in that short selling may amplify changes in the Fund's NAV since it may increase the exposure of the Fund to certain markets and may increase losses and the volatility of returns.

Sovereign Debt Risk
Sovereign debt securities are subject to risk of payment delays or defaults due to, among other things: (1) country cash flow problems, (2) insufficient foreign currency reserves, (3) political considerations, (4) large debt positions relative to the country's economy, (5) policies toward foreign lenders or investors, (6) the failure to implement economic reforms required by the International Monetary Fund or other multilateral agencies, or (7) an inability or unwillingness to repay debts. A governmental entity that defaults on an obligation may request additional time in which to repay loans, may request further loans, or may seek to restructure its obligations to reduce interest rates or outstanding principal. There is no legal process for collecting sovereign debt that a government does not pay, nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected.

Subsidiary Risk
By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary's investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. The principal risks of the Subsidiary are listed in this section of the Prospectus as principal risks of the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved or that, as a result, the investment objective of the Fund will be achieved. The Subsidiary is not registered under the Investment Company Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the Investment Company Act. In addition, changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this Prospectus and the SAI and could adversely affect the Fund's performance.

Tax Risk
To qualify as a "regulated investment company" under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code") ("RIC"), the Fund must, among other requirements, derive at least 90% of its gross income for each taxable year from "qualifying income," which is described in more detail in the "Tax Information" section of the SAI. Income from certain commodity-linked derivative instruments in which the Fund invests is not considered qualifying income. The Fund will therefore restrict its income from direct investments in those instruments, such as commodity-linked swaps, to a maximum of 10% of its gross income for each taxable year. The Fund's investment in the Subsidiary is expected to provide the Fund with exposure to the commodities markets within the limitations of the federal tax requirements of Subchapter M. Treasury regulations provide that income inclusions of a RIC from a controlled foreign corporation ("CFC"), such as the Subsidiary, in which the RIC invests as part of its business of investing in stocks or securities, are qualifying income for the RIC whether or not the CFC makes distributions to the RIC out of its associated earnings and profits for the applicable taxable year. See "Tax Information" in the SAI for further information regarding RIC's federal income tax treatment of income from CFCs and commodity-linked instruments. The federal income tax treatment of the Fund's commodity-linked investments and income from the Subsidiary may be materially adversely affected by future legislation, other Treasury regulations,

and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M or otherwise materially affect the character, timing or recognition, and/or amount of the Fund's taxable income and/or net capital gains and, therefore, the distributions the Fund makes.

Trading System and Execution of Orders Risk
The sub-advisor relies extensively on computer programs, systems, technology, data and models to implement its execution strategies and algorithms. The sub-advisor's investment strategies, trading strategies and algorithms depend on its ability to establish and maintain an overall market position in a combination of financial instruments selected by the sub-advisor. There is a risk that the sub-advisor's proprietary algorithmic trading systems may not be able to adequately react to a market event without serious disruption. Further, trading strategies and algorithms may malfunction, causing severe losses. The successful operation of the computer programs, systems, technology, data and models depends in part on the sub-advisor's ability to ensure those systems remain operational and that appropriate disaster recovery procedures are in place. While the sub-advisor has employed tools to allow for human intervention to respond to significant system malfunctions, it cannot be guaranteed that losses will not occur in such circumstances as unforeseen market events, disruptions and execution system issues.

U.S. Government Securities Risk
A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed 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. U.S. government securities are also subject to credit risk, interest rate risk and market risk. The rising U.S. national debt may lead to adverse impacts on the value of U.S. government securities due to potentially higher costs for the U.S. government to obtain new financing.

U.S. Treasury Obligations Risk
The market value of U.S. Treasury obligations may vary due to fluctuations in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's investments in obligations issued by the U.S. Treasury to decline. Certain political events in the U.S., such as a prolonged government shutdown or potential default on the national debt, may also cause investors to lose confidence in the U.S. government and may cause the value of U.S. Treasury obligations to decline.

Valuation Risk
Certain of the Fund's assets may be valued at a price different from the price at which they can be sold. This risk may be especially pronounced for investments that are illiquid or may become illiquid, or securities that trade in relatively thin markets and/or markets that experience extreme volatility. The valuation of the Fund's investments in an accurate and timely manner may be impacted by technological issues and/or errors by third party service providers, such as pricing services or accounting agents.

Zero Coupon Securities Risk
Zero coupon securities are debt securities that do not make periodic interest payments prior to maturity or a specified redemption date (or cash payment date). Accordingly, zero coupon securities usually trade at a deep discount from their face or par value and will be subject to greater fluctuations in market value in response to changing interest rates than debt obligations of comparable  maturities that make current distribution of interest in cash. While interest payments are not made on such securities, the Fund accrues income with respect to these securities for federal income tax and accounting purposes. Longer term zero-coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds.

Fund Performance

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 are a tax-exempt entity or hold your Fund shares through a tax-deferred arrangement, such as an individual retirement account ("IRA") 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 of the Fund; after-tax returns for other share classes will vary.
