1	A contingent deferred sales charge (‘’CDSC’’) of 0.50% will be charged on certain purchases of $250,000 or more of A Class shares that are redeemed in whole or part within 18 months of purchase.

During the fiscal year ended August 31, 2022, the Fund paid amounts to American Beacon Advisors, Inc. (the “Manager”) that were previously waived and/or reimbursed under a contractual fee waiver/expense reimbursement agreement for the Fund’s A Class, C Class, Y Class, R5 Class, Investor Class and SP Class shares in the amount of 0.01% for the A Class, 0.02% for the C Class, 0.01% for the Y Class, 0.02% for the R5 Class, 0.01% for the Investor Class, and 0.01% for the SP Class shares.

3	The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets provided in the Fund’s Financial Highlights table, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

The Manager has contractually agreed to waive fees and/or reimburse expenses of the Fund’s A Class, C Class, Y Class, R5 Class, Investor Class and SP Class shares, as applicable, through December 31, 2023 to the extent that Total Annual Fund Operating Expenses exceed 1.09% for the A Class, 1.86% for the C Class, 0.88% for the Y Class, 0.82% for the R5 Class, 1.16% for the Investor Class and 1.08% for the SP Class (excluding taxes, interest, brokerage commissions, acquired fund fees and expenses, securities lending fees, expenses associated with securities sold short, litigation, and other extraordinary expenses). The Manager will itself waive fees and/or reimburse expenses of the Fund to maintain the contractual expense ratio caps for each applicable class of shares or make arrangements with other service providers to do so. The contractual expense reimbursement and fee waiver by the Manager can be changed or terminated only in the discretion and with the approval of a majority of the Fund’s Board of Trustees (“Board”). The Manager may also, from time to time, voluntarily waive fees and/or reimburse expenses of the Fund. The Manager can be reimbursed by the Fund for any contractual or voluntary fee waivers or expense reimbursements if reimbursement to the Manager (a) occurs within three years from the date of the Manager’s waiver/reimbursement and (b) does not cause the Total Annual Fund Operating Expenses of a class to exceed the lesser of the contractual percentage limit in effect at the time of the waiver/reimbursement or the time of the recoupment.

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, 2023. 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 assuming the conversion of C Class shares to A Class shares 8 years after purchase. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

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 82% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in income-producing floating-rate loans and other floating-rate debt securities, which may include bonds, notes and debentures issued by corporations, and debt securities issued or guaranteed by the U.S. government or one of its agencies or instrumentalities.

The Fund invests primarily in U.S. dollar-denominated senior secured floating rate corporate loans (“Floating Rate Loans”) made by banks and other large financial institutions to various domestic companies. To a lesser extent, the Fund may invest in loans made to foreign companies as well. Floating Rate Loans are generally senior in the borrowing companies’ capital structures and are typically wholly or partially secured by assets of the borrowing company. Such obligations are primarily below investment grade quality (commonly referred to as “high yield” or “junk” quality obligations) and have below investment grade credit ratings or may be unrated but deemed by the sub-advisor to be of equivalent quality. Credit investments rated below investment grade are generally regarded as having speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. The Fund may also invest in fixed-rate debt securities, which may be unsecured, collateralized loan obligations and exchange-traded funds in an attempt to create a portfolio with an optimal blend of eligible instruments.

A significant portion of the Fund’s investments may be unregistered, restricted as to their resale, and may trade in decentralized markets. Additionally, most Floating Rate Loans in the Fund may be considered “covenant-lite” based on the types of lender protections and borrower obligations in the loan agreements.

The sub-advisor utilizes a combination of top-down and bottom-up research-intensive approaches to achieve the Fund’s objective by identifying fundamentally attractive investments which offer relative value and which pay interest at variable rates based on leading indices, such as ICE LIBOR (“LIBOR”) or the Secured Overnight Financing Rate (“SOFR”), among others, with or without a floor plus a fixed spread. The sub-advisor’s top-down approach includes seeking to establish industry weights by understanding the variables affecting each industry and, therefore, the economy as a whole. The bottom-up approach utilizes the sub-advisor’s proprietary credit technology to analyze quantitative information about all potential investments, combined with fundamental qualitative analysis. The sub-advisor seeks to invest a significant portion of the Fund’s assets in loans that offer attractive relative value, with smaller portions invested in loans deemed likely to outperform the broader market in the near term and in loans that the sub-advisor believes will be driven by a special catalyst and are opportunities for the sub-advisor to take a high-conviction position.

The sub-advisor’s investment process incorporates the sub-advisor’s environmental, social, and/or governance (“ESG”) analysis as a consideration in the assessment of existing and potential investments, which may assist in identifying certain investment risks that may not be apparent absent such consideration. However, as ESG information is just one investment consideration, ESG considerations are not solely determinative in any investment decision made by the sub-advisor. In addition, the sub-advisor does not use ESG considerations to limit, restrict or otherwise exclude companies or sectors from the Fund’s investment universe. The sub-advisor may use ESG research and/or ratings information provided by one or more third parties in performing this analysis and considering ESG risks.

In managing the Fund, the sub-advisor seeks to invest in a portfolio of Floating Rate Loans that it believes will be less volatile over time than the general loan market. The Fund invests in securities without regard to maturity or duration and may invest in obligations of companies of all sizes. The Fund has a target investment life cycle of 18 to 24 months and does not employ a “buy-and-hold” strategy. The sub-advisor generally sells a security when it believes its projected future return becomes unattractive relative to the rest of the portfolio or the investable universe.

The coupons on Floating Rate Loans and other floating-rate debt securities are not fixed and may fluctuate based upon changes in market rates. As short-term interest rates increase, interest payable to the Fund may lag behind the increases in market rates or may have limits on the maximum increases in interest rates. As short-term interest rates decline, interest payable to the Fund typically decreases. Floating Rate Loans typically have mandatory and optional prepayment provisions (also referred to as “calls”). Because of prepayments or calls, the actual remaining maturity of a loan may be considerably less than its stated maturity, and if a Floating Rate Loan is prepaid, the Fund will have to reinvest the proceeds in other loans or instruments which may have lower spreads over their applicable reference rates. In such a case, the amount of interest paid to the Fund would likely decrease.

The Fund may invest a portion of its assets in cash, cash equivalents or other high-quality fixed-income securities in such amounts as the sub-advisor deems appropriate, including when the sub-advisor believes the Fund needs to retain cash. The Fund may invest cash balances in a government money market fund advised by the Manager, with respect to which the Manager receives a management fee. Any such instruments held by the Fund for cash management or defensive investing purposes can fluctuate in value.

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.

2American Beacon FEAC Floating Rate Income Fund - Summary Prospectus

Callable Securities Risk
The Fund may invest in fixed-income securities with call features. A call feature allows the issuer of the security to redeem or call the security prior to its stated maturity date. In periods of falling interest rates, issuers may be more likely to call in securities that are paying higher coupon rates than prevailing interest rates. In the event of a call, the Fund would lose the income that would have been earned to maturity on that security, and the proceeds received by the Fund may be invested in securities paying lower coupon rates and may not benefit from any increase in value that might otherwise result from declining interest rates.

Collateralized Loan Obligations (“CLOs”) Risk
The risks of an investment in a CLO depend largely on the type of underlying collateral and the class or seniority of CLO in which the Fund invests. The Fund typically will invest in CLOs collateralized by bank loans. Therefore, the CLOs in which the Fund invests will be subject to loan interests risk. In addition, CLOs typically are privately offered and sold, and thus, are not registered under the securities laws. As a result, investments in CLOs may be characterized by the Fund as illiquid securities. CLOs may be difficult to value, which could make them highly volatile. CLOs carry the general risks applicable to other fixed income investments, including interest rate risk, credit risk, market risk and liquidity risk. CLOs also carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the quality of the collateral may decline in value or default; (iii) the risk that the Fund may invest in CLOs that are subordinate to other classes in the event of an issuer’s insolvency; and (iv) that the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

Counterparty Risk
The Fund is subject to the risk that a party or participant to a transaction, such as a broker, 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.

“Covenant-Lite” Obligations Risk
Certain investments, such as loans in which the Fund may invest directly or have exposure to through its investments in structured securities, may be “covenant-lite.” Covenant-lite obligations contain fewer maintenance covenants than other obligations, or no maintenance covenants at all, and may not include terms which allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached. The Fund’s exposure to losses on such investments may be increased, especially during a downturn in the credit cycle.

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.

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 and its service providers as well as the ability of shareholders to transact with the Fund, 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 plans and systems of its service providers, its counterparties or the issuers of securities in which the Fund invests. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Debentures Risk
Debentures are unsecured debt securities. The holder of a debenture is protected only by the general creditworthiness of the issuer. The Fund may invest in both corporate and government debentures.

Environmental, Social, and/or Governance Investing Risk
The use of environmental, social, and/or governance (“ESG”) considerations by the sub-advisor may cause the Fund to make different investments than funds that have a similar investment style but do not incorporate such considerations in their strategy. As with the use of any investment considerations involved in investment decisions, there is no guarantee that the use of any ESG investment considerations will result in the selection of issuers that will outperform other issuers or help reduce risk in the Fund. The Fund may underperform funds that do not incorporate these considerations or incorporate different ESG considerations. Although the sub-advisor has established its own process to oversee ESG integration in accordance with the Fund’s strategies, successful integration of ESG factors will depend on the sub-advisor’s skill in researching, identifying, and applying these factors, as well as on the availability of relevant data.

The regulatory landscape with respect to ESG investing in the United States is evolving and any future rules or regulations may require the Fund to change its investment process with respect to the integration of ESG factors.

Foreign Exposure Risk
Exposure to obligations of non-U.S. issuers carries potential risks not associated with investments in obligations of U.S. issuers. Such risks may include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing and financial reporting standards, (5) greater volatility, (6) different government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays in transaction settlement in some foreign markets. 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. Global economic and financial markets have become increasingly interconnected and conditions (including recent volatility and 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.

High-Yield Securities Risk
Exposure to high-yield, below investment-grade securities (commonly referred to as “junk bonds”) generally involves significantly greater risks 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. These securities also may be difficult to sell at the time and price the Fund desires. 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. High-yield securities may experience greater price volatility and less liquidity than investment grade securities. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment.

Interest Rate Risk
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. 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 rates may rise, perhaps significantly and/or rapidly, potentially resulting in substantial losses to the

American Beacon FEAC Floating Rate Income Fund - Summary Prospectus3

Fund. Interest rate changes may have a more pronounced effect on the market value of fixed-rate instruments than on floating-rate instruments. The value of floating rate and variable securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The prices of fixed-income securities are also affected by their durations. Fixed-income securities with longer durations generally have greater sensitivity to changes in interest rates. 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 two years, a 1% increase in interest rates could be expected to result in a 2% decrease in the value of the bond. An increase in interest rates can impact markets broadly as well. To the extent the Fund holds an investment with a negative interest rate to maturity, the Fund may generate a negative return on that investment.

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 that 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.

LIBOR Risk
Certain of the instruments identified in the Fund’s principal investment strategies have coupon rates or may provide exposure to underlying investments with coupon rates, that are based on the ICE LIBOR (“LIBOR”), the Secured Overnight Financing Rate (“SOFR”), Euro Interbank Offered Rate and other similar types of reference rates (each, a “Reference Rate”). These Reference Rates are generally intended to represent the rate at which contributing banks may obtain short-term borrowings within certain financial markets. Most maturities and currencies of LIBOR were phased out at the end of 2021, with the remaining ones to be phased out on June 30, 2023. These events and any additional regulatory or market changes may have an adverse impact on the Fund or its investments, including increased volatility or illiquidity in markets for instruments that rely on LIBOR. There remains uncertainty regarding the impact of the transition from LIBOR on the Fund and the financial markets generally. SOFR has been selected by a committee established by the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York to replace LIBOR as a Reference Rate in the United States and U.S. law requires that contracts without a practicable LIBOR alternative default to SOFR plus a set spread beginning in mid-2023. Other countries have undertaken similar initiatives to identify replacement Reference Rates for LIBOR in their respective markets. However, there are obstacles to converting certain existing investments and transactions to a new Reference Rate, as well as risks associated with using a new Reference Rate with respect to new investments and transactions. The transition process, or the failure of an industry to transition, could lead to increased volatility and illiquidity in markets for instruments that currently rely on LIBOR to determine interest rates and a reduction in the values of some LIBOR-based investments, all of which would impact the Fund. Since the usefulness of LIBOR as a benchmark could deteriorate during the transition period, these effects could occur prior to June 30, 2023. At this time, it is not possible to completely identify or predict the effect of any transition, establishment of alternative Reference Rates or other reforms to Reference Rates that may be enacted in the UK or elsewhere. In addition, any substitute Reference Rate and any pricing adjustments imposed by a regulator or by counterparties or otherwise may adversely affect the Fund’s performance and/or NAV.

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. For example, liquidity risk may be magnified in rising interest rate environments in the event of higher-than-normal redemption rates. Unexpected redemptions may force the Fund to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

Loan Interests Risk
In making investments in bank loans or senior loans, the Fund will depend primarily on the creditworthiness of the borrower for payment of principal and interest and will also rely on the financial institution to make principal and interest payments to the Fund once it receives payment on the underlying loan. The Fund will also rely on the financial institution to pursue appropriate remedies against a borrower in the event that the borrower defaults. As such, the Fund may be exposed to the credit risk of both the financial institution that made the loan and the underlying borrower.

Unlike publicly traded common stocks, which trade on national exchanges, there is no central place or exchange for loans, including bank loans and senior loans, to trade. There is a risk that the value of any collateral securing a loan in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. In the event that the borrower defaults, the Fund’s access to the collateral may be limited or delayed by bankruptcy or other insolvency laws. 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 with respect to the Fund’s ability to pay redemption proceeds within the allowable time periods stated in the Prospectus. The secondary market for loans also may be subject to irregular trading activity and wide bid/ask spreads. The lack of an active trading market for certain 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. Accordingly, loan interests may at times be illiquid. 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.

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. Equity securities generally have greater price volatility than fixed-income securities, although under certain market conditions fixed-income securities may have comparable or greater price volatility. During a general downturn in the securities markets, multiple assets may decline in value simultaneously. Prices in many financial markets have increased significantly over the last decade, but there have also been periods of adverse market and financial developments and cyclical change during that timeframe, which have resulted in unusually high levels of volatility in domestic and foreign financial markets that has caused losses for investors and may occur again in the future. The value of a security may decline due to adverse issuer-specific conditions, general market conditions unrelated to a particular issuer, such as changes in interest or inflation rates, or factors that affect a particular industry or industries. Changes in the financial condition of a single issuer or market segment also can impact the market as a whole. Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, pandemics, public health crises, natural disasters and related events have led, and in the future may continue to lead, to instability in world economies and markets generally and reduced liquidity in equity, credit and fixed-income markets, which may disrupt economies and markets and adversely affect the value of your investment. Changes in value may be temporary or may last for extended periods.

4American Beacon FEAC Floating Rate Income Fund - Summary Prospectus

Policy changes by the U.S. government and/or Federal Reserve and political events within the U.S. and abroad, such as changes in the U.S. presidential administration and Congress, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown and threats not to increase the federal government’s debt limit, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Markets and market participants are increasingly reliant upon both publicly available and proprietary information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large.

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.

■

Recent Market Events Risk. Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. Moreover, the risks discussed herein associated with an investment in the Fund may be increased. An outbreak of infectious respiratory illness caused by a novel coronavirus, known as COVID-19, was first detected in late 2019 and has subsequently spread globally. The transmission of various variants of COVID-19, and efforts to contain their spread, have resulted, and may continue to result, in significant disruptions to business operations, travel restrictions and closed borders, and lower consumer demand, as well as general concern and uncertainty that has negatively affected the global economy. Any resurgence of COVID-19, a variant or other significant viruses could negatively impact the Fund and adversely impact the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time.
Although interest rates were unusually low in recent years in the U.S. and abroad, in March 2022, the Federal Reserve began to raise interest rates as part of its efforts to address rising inflation. It is difficult to accurately predict the pace at which the Federal Reserve will continue to increase interest rates, or the timing, frequency or magnitude of any such increases. Additionally, various economic and political factors could cause the Federal Reserve to change its approach in the future and the Federal Reserve’s actions may result in an economic slowdown. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market.
Slowing global economic growth; risks associated with a trade agreement between the United Kingdom and the European Union; the risks associated with ongoing trade negotiations with China; the possibility of changes to some international trade agreements; tensions, war, or open conflict between nations, such as between Russia and Ukraine or in eastern Asia; political or economic dysfunction within some nations, including major producers of oil; economic stimulus by the Japanese central bank; and dramatic changes in commodity and currency prices could affect the economies of many nations, including the United States, in ways that cannot necessarily be foreseen at the present time. Russia’s military invasion of Ukraine beginning in February 2022, the responses and sanctions by the United States and other countries, and the potential for wider conflict have had, and could continue to have, severe adverse effects on regional and global economies and could further increase volatility and uncertainty in the financial markets and the prices of various commodities.
Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change, including on the demand for and the development of goods and services and related production costs, and the impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences of regulation or business trends driven by climate change.

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.

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:

■

Exchange-Traded Funds (“ETFs”) Risk. Because ETFs are listed on an exchange, they may be subject to trading halts, may trade at a premium or discount to their net asset value (“NAV”) and may not be liquid. An ETF that tracks an index may not precisely replicate the returns of that index, and an actively-managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. Future legislative or regulatory changes, including changes in taxation, could impact the operation of ETFs.

■	Government Money Market Funds Risk. Investments in government money market funds are subject to interest rate risk, credit risk, and market risk.

Prepayment and Extension Risk
Prepayment risk is the risk that the principal amount of a bond may be repaid prior to the bond’s maturity date. Due to a decline in interest rates or excess cash flow into the issuer, a debt security may be called or otherwise converted, prepaid or redeemed before maturity. If this occurs, no additional interest will be paid on the investment. The Fund may have to reinvest the proceeds in another investment 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. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. 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, increase the risk of default and delayed payment, heighten interest rate risk and increase the potential for a decline in its price. In addition, as a consequence of a decrease in prepayments, the amount of principal available to the Fund for investment would be reduced.

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. The sale of assets to meet redemption requests may create net capital gains or losses, which could cause the Fund to have to distribute substantial capital gains.

Reliance on Corporate Management and Financial Reporting Risk
The sub-advisor may select investments for the Fund in part on the basis of information and data made directly available to the sub-advisor by the issuers of securities or through sources other than the issuers such as collateral pool servicers. The sub-advisor has no ability to independently verify such information and

American Beacon FEAC Floating Rate Income Fund - Summary Prospectus5

data and is therefore dependent upon the integrity of the management of these issuers and of such servicers and the financial and collateral performance reporting processes in general. Information and data provided regarding a particular issuer may not necessarily contain information that the sub-advisor normally considers when evaluating the investment prospects of a company.

Restricted Securities Risk
Securities not registered in the U.S. under the Securities Act of 1933, as amended (the “Securities Act”), or in non-U.S. markets pursuant to similar regulations, including “Section 4(a)(2)” securities and “Rule 144A” securities, are restricted as to their resale. Such securities may not be listed on an exchange and may have no active trading market. The prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. 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 or may have to be held for a certain time period before they can be resold. 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.

Secured, Partially Secured and Unsecured Obligation Risk
Debt obligations may be secured, partially secured or unsecured. Interests in secured and partially-secured obligations have the benefit of collateral and, typically, of restrictive covenants limiting the ability of the borrower to further encumber its assets. However, there is no assurance that the liquidation of collateral from a secured or partially-secured obligation would satisfy the borrower’s obligation, or that the collateral can be liquidated. Furthermore, there is a risk that the value of any collateral securing an obligation in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the obligation. In the event the borrower defaults, the Fund’s access to the collateral may be limited or delayed by bankruptcy or other insolvency laws. Unsecured debt, including senior unsecured and subordinated debt, will not be secured by any collateral and will be effectively subordinated to a borrower’s secured indebtedness (to the extent of the collateral securing such indebtedness). With respect to unsecured obligations, the Fund lacks any collateral on which to foreclose to satisfy its claim in whole or in part. Such instruments generally have greater price volatility than that of fully secured holdings and may be less liquid.

Securities Selection Risk
Securities selected for the Fund may not perform to expectations. This could result in the Fund’s underperformance compared to its benchmark index(es), or other funds with similar investment objectives or strategies.

Unrated Securities Risk
Because the Fund may purchase securities that are not rated by any rating organization, the sub-advisor, after assessing their credit quality, may internally assign ratings to certain of those securities in categories similar to those of rating organizations. Unrated securities are subject to the risk that the sub-advisor may not accurately evaluate the security’s comparative credit rating. Some unrated securities may not have an active trading market or may be difficult to value, which means the Fund might have difficulty selling them promptly at an acceptable price. Unrated securities may be subject to greater liquidity risk and price volatility.

U.S. Government Securities 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 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’’), Federal Home Loan Mortgage Corporation (‘‘Freddie Mac’’), Federal Home Loan Bank (‘‘FHLB’’), Federal Farm Credit Bank (“FFCB”), 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, and no assurance can be given that the U.S. government will provide financial support if these organizations do not have the funds to meet future payment obligations. U.S. government securities and securities of government-sponsored entities 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.

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 that are illiquid or may become illiquid, or securities that trade in relatively thin markets and/or markets that experience extreme volatility. The Fund’s ability to value its 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.

Variable and Floating Rate Securities Risk
The coupons on variable and floating-rate securities are not fixed and may fluctuate based upon changes in market rates. A variable rate security has a coupon that is adjusted at pre-designated periods in response to changes in the market rate of interest on which the coupon is based. The coupon on a floating rate security is generally based on an interest rate, such as a money-market index, LIBOR, Secured Overnight Financing Rate (“SOFR”), or a Treasury bill rate. Variable and floating rate securities are subject to interest rate risk and credit risk. As short-term interest rates decline, the coupons on variable and floating-rate securities typically decrease. Alternatively, during periods of rising short-term interest rates, the coupons on variable and floating-rate securities typically increase. Changes in the coupons of variable and floating-rate securities may lag behind changes in market rates or may have limits on the maximum increases in the coupon rates. The value of variable and floating-rate securities may decline if their coupons do not rise as much, or as quickly, as interest rates in general. Conversely, variable and floating rate securities will not generally increase in value if interest rates decline. Certain types of variable and floating rate instruments may be subject to greater liquidity risk than other debt securities.

Fund Performance

The bar chart and table below provide an indication of risk by showing changes in the Fund’s performance over time. The bar chart shows how the Fund’s performance has varied from year to year. The table shows how the Fund’s average annual total returns compare to a broad-based market index, which is the Fund’s benchmark index and was the benchmark index of the Fund’s predecessor, for the periods indicated. Effective December 31, 2022, a new sub-advisor began managing the Fund. Performance through December 30, 2022 reflects the Fund’s performance under the management of its prior sub-advisor.

Each of the Fund’s share classes commenced operations on December 11, 2015. On that date, the Fund acquired all the assets and assumed all the liabilities of the Fund’s predecessor. The SP Class shares and R5 Class shares of the Fund have adopted the performance history and financial statements of the Investor Class shares and Institutional Class shares, respectively, of the Fund’s predecessor.

In the bar chart and table below, as applicable, for the period prior to December 11, 2015, the performance of the Fund’s R5 Class, Investor Class, A Class, C Class and Y Class shares reflects the returns of the Institutional Class shares of the Fund’s predecessor, and the performance of the Fund’s SP Class shares reflects the returns of the predecessor fund’s Institutional Class shares from December 3, 2012 through May 29, 2014, and the returns of the predecessor fund’s Investor Class shares from May 30, 2014 through December 10, 2015. In each case, the newer share classes would have had similar annual returns to the applicable share classes of the Fund’s predecessor because the shares of each class represent investments in the same portfolio securities. However, the share classes of the Fund’s predecessor had different expenses than the newer share classes, which would affect performance. To the extent that the share classes of the Fund’s predecessor

6American Beacon FEAC Floating Rate Income Fund - Summary Prospectus

had lower expenses than the newer share classes, the performance of the share classes of the Fund’s predecessor would likely have been higher than the newer share class would have realized during the same period. The R5 Class, Investor Class, A Class, C Class, Y Class and SP Class performance shown in the table has not been adjusted for differences in operating expenses between those share classes and the predecessor fund’s applicable share class, but the A Class and C Class shares performance has been adjusted for the impact of the maximum applicable sales charge.

With respect to the SP Class shares, for the period from December 3, 2012 through May 29, 2014, the Investor Class shares of the Fund’s predecessor would have had similar annual returns to the Institutional Class shares of the Fund’s predecessor because the shares of each class represent investments in the same portfolio securities. However, the Institutional Class shares of the Fund’s predecessor had different expenses than the Investor Class shares of the Fund’s predecessor, which would affect performance. To the extent that the Institutional Class shares of the Fund’s predecessor had lower expenses than the Investor Class shares of the Fund’s predecessor, the performance of the Institutional Class shares of the Fund’s predecessor would likely have been higher than the Investor Class shares of the Fund’s predecessor would have realized during the same period. The SP Class performance shown in the table has not been adjusted for differences in operating expenses between the predecessor fund’s Investor Class and Institutional Class shares.

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 the Fund’s R5 Class shares; after-tax returns for other share classes will vary.
