| 1 | American Beacon Advisors, Inc. (the "Manager") has contractually agreed to waive fees and/or reimburse expenses of the Fund's Y Class, R6 Class, R5 Class, and Investor Class shares through February 28, 2027 to the extent that Total Annual Fund Operating Expenses exceed 0.51% for the Y Class, 0.41% for the R6 Class, 0.45% for the R5 Class, and 0.83% for the Investor 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 contractual expense reimbursement 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 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 Manager can be reimbursed by the Fund for any contractual fee waivers or expense reimbursements if reimbursement to the Manager (a) occurs within three years 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 February 28, 2027. Although your actual costs may be higher or lower, based on these assumptions, whether you redeem or hold your shares, 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 33% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in investment grade bonds. For purposes of the 80% policy, investment grade bonds include other investment grade debt securities. The Fund considers investment grade debt securities to be debt securities that are rated A-/A3 or better by S&P Global Ratings ("S&P"), Moody's Investors Service, Inc. ("Moody's") or Fitch Ratings Inc. ("Fitch").

GHQB030126

**American Beacon Garcia Hamilton Quality Bond Fund** - Summary Prospectus**1**

------

The types of investment grade debt securities that the Fund invests in primarily include obligations of the U.S. Government (such as U.S. Treasuries), its agencies and instrumentalities, including U.S. Government-sponsored enterprises (some of which are not backed by the full faith and credit of the U.S. Government), corporate bonds, debentures, and mortgage-backed and mortgage-related securities, including mortgage pass-through securities. These types of obligations may have fixed-rate or floating-rate coupons (or variable rate coupons), which pay interest at variable rates based on a lending rate, such as the Secured Overnight Financing Rate ("SOFR"), and are commonly referred to as fixed income securities or bonds. If an investment held by the Fund is downgraded below investment grade, the sub-advisor may sell the security or request the Manager's permission to continue to hold the security.

In selecting investment grade debt securities within the corporate sector, the sub-advisor first focuses on the largest U.S. issuers and companies rated A-/A3 or better by at least two rating agencies. The sub-advisor then utilizes screens to identify issuers that carry high levels of unquantifiable risk that could have a financial impact on the issuers, which includes risks associated with environmental, social, and/or governance ("ESG") considerations. This includes, but is not limited to, risks associated with foreign companies, Yankee bonds, alcohol, tobacco, gambling, and defense contractors. Issuers identified as having a higher risk profile during this stage are either excluded from further consideration or subject to further evaluation to determine their inclusion in the investable universe. The sub-advisor then utilizes research and/or rankings provided by one or more third parties to analyze and scale the remaining issuers based on the sustainability of their operations and their consideration of ESG principles as an integrated part of the sub-advisor's evaluation and investment process. These investment considerations are not solely determinative in any investment decision. Thereafter, if the sub-advisor deems securities to be comparable from an investment perspective, the sub-advisor generally expects to select for the Fund's portfolio the securities with the highest ranking consistent with the sub-advisor's proprietary scale methodology.

Under normal circumstances, the Fund seeks to maintain a weighted-average duration that is 10% above or below the Fund's benchmark, with a maximum duration range of above or below 25% for extreme market conditions. The Fund uses the Bloomberg US Aggregate Bond Index ("Benchmark"). As of December 31, 2025, the Benchmark's duration was 6.0 years, which means that the Fund's duration would have been expected to range from approximately 5.4 years to approximately 6.6 years at that time under normal circumstances, and in extreme market conditions, to range from approximately 4.5 years to approximately 7.5 years at that time. The Benchmark's duration is expected to change over time and could be higher or lower at a future date, and the Fund's duration may change accordingly. Duration is an indicator of a bond's price sensitivity to a change in interest rates. For example, a duration of eight years means that a security's price would be expected to decrease by approximately 8% with a 1% increase in interest rates. The Fund may invest in securities of any maturity, but typically invests in securities with maximum maturities of up to 30 years.

The sub-advisor follows a fixed income investment strategy that focuses on high current income, given its outlook for interest rates, and the preservation of capital. In selecting securities for the Fund, the sub-advisor employs a top-down approach, which includes a broad fundamental analysis of the current fixed income markets, including duration, the yield curve, and the performance of market sectors. Through this analysis, the sub-advisor creates defined parameters for the selection of investments for the Fund's portfolio and implements a proprietary investment process comprised of qualitative and quantitative components.

The Fund may have a focused portfolio of fewer companies than other diversified funds. 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.

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 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.

**Callable Securities Risk**<br>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.

**Counterparty Risk**<br>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.

**Credit Risk**<br>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**<br>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.

**Debentures Risk**<br>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**<br>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 choose not to, or may not be able to, take advantage of certain investment opportunities due to these considerations, which may adversely affect investment performance. The Fund may underperform funds that do not incorporate these considerations or

**2** **American Beacon Garcia Hamilton Quality Bond Fund** - Summary Prospectus

------

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 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. 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.

**Focused Holdings Risk**<br>Because the Fund may have a focused portfolio of fewer companies than other diversified funds, the increase or decrease of the value of a single investment may have a greater impact on the Fund's net asset value ("NAV") and total return when compared to other diversified funds.

**Interest Rate Risk**<br>Generally, the value of investments with interest rate risk, such as fixed-income securities, 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 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 are also affected by their durations. Fixed-income securities 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**<br>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**<br>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.

**Liquidity Risk**<br>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.

**Market Risk**<br>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.

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.

■ 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, during periods of significant volatility, the risks discussed herein associated with an investment
 in the Fund may be
 increased. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions
 in one country or
 region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may
 be changing, which
 may impact such economies and markets in ways that cannot be foreseen at this time. <br> Some
 countries, including the  U.S., have adopted more protectionist trade policies, including trade tariffs and other trade barriers,
 which is a trend that appears to
 be continuing globally. The economies of all nations, including the U.S., are subject to the risks of slowing global economic growth,
 protectionist trade policies,
 inflationary pressures, limits imposed by international trade and security agreements, political or economic dysfunction, poor consumer
 sentiment, and reduced
 demand for goods due to fluctuating commodity prices and currency values, and these risks may create significant market volatility in
 ways that cannot be
 foreseen at the present time. These economic risks could have a negative impact on the Fund's investments. <br> The
 U.S. Federal Reserve and certain foreign central banks have started to lower interest rates, though economic or other factors could stop
 or reverse such changes.
 It is difficult to accurately predict the various economic and political factors that influence the pace at which interest rates might
 change, the timing, frequency
 or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. Changes in interest rates
 could lead to an economic
 slowdown in the U.S. and abroad, significant market volatility and reduced liquidity in certain sectors of the market. <br> Tensions,
 war, or open conflict between nations, such as between Russia and Ukraine, in the Middle East or in eastern Asia could affect the economies
 of many nations, including
 the United States. The duration of ongoing hostilities and sanctions cannot be predicted. Those events present material uncertainty and
 risk with respect
 to markets globally and the performance of the Fund and its investments or operations could be negatively impacted. <br> Advancements
 in technology, including advanced development and increased regulation of artificial intelligence, may adversely impact market movements
 and

------

liquidity. As artificial intelligence is used more widely, which can occur relatively rapidly, the profitability and growth of certain issuers and industries may be negatively impacted in ways that cannot be foreseen and could adversely impact issuer and market performance. As a consequence, the Fund's holdings and its overall performance could be negatively impacted.<br>Global climate change may affect property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change in ways that cannot be foreseen. The impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences that may not be foreseen, may negatively impact certain issuers, industries and regions.

**Mortgage-Backed and Mortgage-Related Securities Risk**<br>Investments in mortgage-backed and mortgage-related securities are influenced by the factors affecting the mortgages underlying the securities or the housing market. These securities tend to be more sensitive to changes in interest rates than other types of debt securities. Investments in mortgage-backed and mortgage-related securities also are subject to market risks for fixed-income securities, which include, but are not limited to, credit risk, interest rate risk, prepayment and extension risk, callable securities risk, valuation risk, liquidity risk, and restricted securities risk. A decline in the credit quality of the issuers of mortgage-backed and mortgage-related securities or instability in the markets for such securities may affect the value and liquidity of such securities, which could result in losses to the Fund. These securities are also subject to the risk of default on the underlying mortgages, particularly during periods of market downturn, and an unexpectedly high rate of defaults on the underlying assets will adversely affect the security's value.

■ Mortgage
 Pass-Through Securities Risk. Mortgage pass-through securities provide for the "pass through" of the monthly payments made by individual borrowers
 on their residential or commercial mortgage loans, net of any fees by the security issuer and guarantor, as applicable, to the holder
 of the security. Mortgage
 pass-through securities are sensitive to interest rate changes, and small movements in interest rates, both increases and decreases, may
 quickly and significantly
 affect the value of certain mortgage pass-through securities. Mortgage pass-through securities involve interest rate risk, credit risk,
 prepayment risk and
 extension risk.

**Other Investment Companies Risk**<br>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:

■ 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**<br>Prepayment and extension risk is the risk that a bond or other fixed-income security or investment might, in the case of prepayment risk, be called or otherwise converted, prepaid or redeemed before maturity and, in the case of extension risk, that the investment might not be prepaid as expected. 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, any of which could result in a reduced yield to the Fund. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. Conversely, 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 or delayed payment, heighten interest rate risk and increase the potential for a decline in an investment's price. In addition, as a consequence of a decrease in prepayments, the amount of principal available to the Fund for investment would be reduced. Extensions of obligations could cause the Fund to exhibit additional volatility and hold securities paying lower-than-market rates of interest. Either case could hurt the Fund's performance.

**Redemption Risk**<br>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.

**Secured, Partially Secured and Unsecured Obligation Risk**<br>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**<br>Securities selected for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to its performance index(es), or other funds with similar investment objectives or strategies.

**U.S. Government Securities and Government-Sponsored Enterprises Risk**<br>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 coupons and the face value at maturity, not its current market price. The market prices for such securities are not guaranteed and will fluctuate. Certain 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''), and Federal Farm Credit Bank ("FFCB"), 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 enterprises 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. It is possible that the U.S. government and government-sponsored enterprises will not have the funds to meet their payment obligations in the future.

**Variable and Floating Rate Securities Risk**<br>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, 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 securities market index for the periods indicated.

The chart and the table show the performance of the Fund's Investor Class shares for all periods. In the table below, for the period prior to February 28, 2019, the performance of the R6 Class shares reflects the returns of the R5 Class shares of the Fund. The R6 Class shares would have had similar annual returns to the R5 Class shares of the Fund because the shares of each class represent investments in the same portfolio securities. However, as reflected in the table in the "Fees and Expenses of the Fund" section of this Fund Summary, the expenses of the R5 Class shares differ from those of the R6 Class shares, which would affect performance. To the extent that the R5 Class shares may have had lower expenses than the R6 Class shares prior to February 28, 2019, the performance of the R5 Class shares would likely have been higher than the performance the R6 Class shares would have realized during the same period. The performance of the R6 Class shares shown in the table has not been adjusted for differences in operating expenses between the R6 Class shares and R5 Class shares.

You may obtain updated performance information on the Fund's website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

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.

Tax Information

Dividends, capital gains distributions, and other distributions, if any, that you receive as a result of your investment in the Fund are subject to federal income tax and may also be subject to state and local income taxes, unless you are a tax-exempt entity or your account is tax-deferred, such as an individual retirement account ("IRA") or a 401(k) plan (in which case you may be taxed later, upon the withdrawal of your investment from such account or plan).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and the Fund's distributor, Resolute Investment Distributors, Inc., or the Manager may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your individual financial professional to recommend the Fund over another investment. Ask your individual financial professional or visit your financial intermediary's website for more information.
