American Beacon U.S. Government Money Market Select Fund^SM

Investment Objective

The Fund's investment objective is current income, liquidity and the maintenance of a stable price of $1.00 per share.

Fees and Expenses of the Fund

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.


Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the value of your investment)

Management Fees	0.10 %
Distribution and/or Service (12b-1) Fees	0.00 %
Other Expenses¹	0.10 %
Acquired Fund Fees and Expenses	0.04 %
Total Annual Fund Operating Expenses²	0.24 %

During the fiscal year ended December 31, 2023, the Fund paid amounts to American Beacon Advisors, Inc. (the "Manager") that were previously waived and/or reimbursed by the Manager under a voluntary fee waiver/expense reimbursement agreement for the Fund's shares in the amount of 0.05%. 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.

2	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.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, whether you redeem or hold your shares, your costs would be:


	1 Year	3 Years	5 Years	10 Years
American Beacon U.S. Government Money Market Select Fund	$24	$76	$133	$301

Principal Investment Strategies

In pursuing its investment objective and implementing its investment strategies, the Fund invests only in securities that comply with the quality, maturity, liquidity, diversification and other requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended (the "Investment Company Act"), which regulates money market mutual funds.

Under normal market conditions, the Fund invests at least 99.5% of its total assets in: (1) debt securities issued or guaranteed as to principal or interest by the U.S. Government, its agencies or instrumentalities ("Government Securities"), (2) repurchase agreements that are collateralized fully by cash or Government Securities; (3) other government money market funds; and/or (4) cash. The Fund also has adopted a policy to invest, under normal market conditions, at least 80% of its net assets in Government Securities, repurchase agreements that are collateralized fully by cash or Government Securities, and/or other government money market funds.

The Fund's investments in U.S. dollar denominated Government Securities may include direct obligations of the U.S. Treasury (such as Treasury bills, Treasury notes and Treasury bonds) and obligations issued or guaranteed as to principal and interest (but not as to market value) by the U.S. Government, its agencies or its instrumentalities, which are backed by the full faith and credit of the U.S. Government. The Government Securities in which the Fund invests also may include debt obligations of U.S. Government-sponsored enterprises, such as the Federal National Mortgage Association ("Fannie Mae"), the Federal Home Loan Mortgage Corporation ("Freddie Mac"), Federal Home Loan Banks ("FHLB"), and Federal Farm Credit Banks ("FFCB"). Although chartered or sponsored by Acts of Congress, these entities are not backed by the full faith and credit of the U.S. Government.

Securities purchased by the Fund generally have remaining maturities of 397 days or less. The dollar-weighted average maturity ("WAM") and dollar-weighted average life ("WAL") of the Fund will be maintained at or below 60 and 120 days, respectively. The Fund uses the amortized cost method of valuation to seek to maintain a stable $1.00 net asset value ("NAV") per share price.

The Fund intends to qualify as a "government money market fund," as such term is defined in or interpreted under Rule 2a-7 under the Investment Company Act. "Government money market funds" are exempt from requirements that money market funds impose a liquidity fee. While the Fund's Board of Trustees may elect to subject the Fund to a liquidity fee in the future, the Board of Trustees has not elected to do so at this time and currently has no intention of doing so.

Principal Risks

There is no assurance that the Fund will achieve its investment objective. The Fund is not designed for investors seeking capital appreciation. 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. Money market funds are subject to specific rules that affect the manner in which these funds are structured and operated. These rules are subject to change. A change in these rules may impact a money market fund's expenses, operations, returns and liquidity.

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.

Prospectus- Fund Summary1

Back to Table of Contents

Credit Risk
The value of a security held by the Fund may decline if the security's credit quality, or that of the security's issuer or provider of credit support, is downgraded or their credit quality otherwise falls. A decline in the credit rating of an individual security held by the Fund may have an adverse impact on its price. Rating agencies might not always change their credit rating on an issuer or security in a timely manner to reflect events that could affect the issuer's ability to make timely payments on its obligations. As with any money market fund, there is the risk that the issuers or guarantors of securities owned by the Fund, including securities issued by U.S. Government agencies, which are not backed by the full faith and credit of the U.S. Government, will default on the payment of principal or interest or the obligation to repurchase securities from the Fund. This could cause the Fund's NAV to decline below $1.00 per share.

Interest Rate Risk
Generally, the value of investments with interest rate risk will move in the opposite direction asmovements in interest rates. When interest rates go up, the market values of previously issued money market instruments generally decline and may have an adverse effect on the Fund's ability to maintain a stable $1.00 share price. A decline in short-term interest rates or a low interest rate environment would lower the Fund's yield and the return on your investment, which may have an adverse effect on the Fund's ability to provide a positive yield to its shareholders. A zero interest rate environment may prevent the Fund from providing a positive yield to shareholders or paying the Fund's expenses out of Fund assets and could impair the Fund 's ability to maintain a stable net asset value. Changes in interest rates also may change the resale value of the instruments held in the Fund's portfolio.

Investment Risk
You could lose money by investing in the Fund.Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may 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 at favorable times or prices can adversely affect the Fund's ability to maintain a $1.00 share price. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. In addition, the Fund may experience difficulty satisfying redemption requests within the time periods stated in the "Redemption Policies" section of this Prospectus because of unusual market conditions, an unusually high volume of redemption requests or other reasons.

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.

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.

■

Although interest rates were unusually low in recent years in the U.S. and abroad, in 2022, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase or start decreasing, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or reverse course. Additionally, various economic and political factors could cause the Federal Reserve or another foreign central bank to change their approach in the future and such actions may result in an economic slowdown in the U.S. and abroad. Unexpected changes in interest rates could lead to significant market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility, reduce liquidity across various markets or decrease confidence in the markets. Additionally, high public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

In March 2023, the shutdown of certain financial institutions in the U.S. and questions regarding the viability of other financial institutions raised economic concerns over disruption in the U.S. and global banking systems. There can be no certainty that the actions taken by the U.S. or foreign governments will be effective in mitigating the effects of financial institution failures on the economy and restoring public confidence in the U.S. and global banking systems.

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. 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; and the possibility of changes to some international trade agreements; political or economic dysfunction within some nations, including major producers of oil; and dramatic changes in commodity and currency prices could have adverse effects that cannot be foreseen at the present time.

2Prospectus- Fund Summary

Back to Table of Contents

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 in the Middle East and between Russia and Ukraine, and any sanctions and related events 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.

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.

Net Asset Value Risk
There is no assurance that the Fund will meet its investment objective of maintaining a stable price of $1.00 per share on a continuous basis. Furthermore, there can be no assurance that the Fund's affiliates will purchase distressed assets from the Fund, make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a NAV of $1.00 per share. If the Fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), the Fund, along with other money market funds, could be subject to increased redemption activity.

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. The Fund will be subject to the risks associated with the underlying 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.

Repurchase Agreement Risk
The use of repurchase agreements involves counterparty risk and credit risk. The obligations of a counterparty to a repurchase agreement are not guaranteed. The Fund permits various forms of securities as collateral whose values fluctuate and that are not issued or guaranteed by the U.S. government. There are risks that a counterparty may default at a time when the collateral has declined in value, or a counterparty may become insolvent and subject to liquidation, which may affect the Fund's right to control the collateral.

U.S. Treasury Obligations Risk
The market value of U.S. Treasury obligations may vary due to fluctuationsin 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.

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, 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 measure of market performance, the Lipper Institutional U.S. Government Money Market Average. Prior to April 29, 2016, the Fund invested in certain types of securities that are no longer generally permitted for "government money market funds," as currently defined in Rule 2a-7 under the Investment Company Act. Consequently, the performance shown below may have been different if the current limitation on the Fund's investments had been in effect. Past performance is not necessarily an indication of how the Fund will perform in the future.

Additional Information About Investment Policies

Investment Objective

The Fund's investment objective is current income, liquidity and the maintenance of a stable price of $1.00 per share.

The Fund's investment objective is "fundamental," which means that it may be changed only with the approval of Fund shareholders.

80% Investment Policy

The Fund has a non-fundamental policy to invest, under normal market conditions, at least 80% of its net assets in debt securities issued or guaranteed as to principal or interest by the U.S. Government, its agencies or instrumentalities ("Government Securities"), repurchase agreements that are collateralized fully by cash or Government Securities, and/or other government money market funds. If the Fund changes its 80% investment policy, a notice will be sent to shareholders at least 60 days in advance of the change and this Prospectus will be supplemented.

Temporary Defensive Policy

The Fund may depart from its principal investment strategy by taking temporary defensive or interim positions in response to adverse market, economic, political,or other conditions. During these times, the Fund may not achieve its investment objective.

Back to Table of Contents

Additional Information About Risks

Below is additional information about the Fund's principal risk factors in light of its principal investment strategies. 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.

Credit Risk
The value of a security held by the Fund may decline if the security's credit quality, or that of the security's issuer or provider of credit support, is downgraded or their credit quality otherwise falls. Securities are subject to varying degrees of credit risk, which are often reflected in their credit ratings. A decline in the credit rating of an individual security held by the Fund may have an adverse impact on its price and may make it difficult for the Fund to sell it. Ratings represent a rating agency's opinion regarding the quality of the security and are not a guarantee of quality. Rating agencies might not always change their credit rating on an issuer or security in a timely manner to reflect events that could affect the issuer's ability to make timely payments on its obligations. As with any money market fund, there is the risk that the issuers or guarantors of securities owned by the Fund, including securities issued by U.S. Government agencies, which are not backed by the full faith and credit of the U.S. Government, will default on the payment of principal or interest or the obligation to repurchase securities from the Fund. This could cause the Fund's NAV to decline below $1.00 per share. U.S. government securities held by the Fund are supported by varying degrees of credit, and their value may fluctuate in response to political, market or economic developments. U.S. Government securities, especially those that are not backed by the full faith and credit of the U.S. Treasury, such as securities supported only by the credit of the issuing governmental agency or government-sponsored enterprise, carry at least some risk of nonpayment, and the maximum potential liability of the issuers of such securities may greatly exceed their current resources. There is no assurance that the U.S. Government would provide financial support to the issuing entity if not obligated to do so by law. Further, any government guarantees on U.S. Government securities that the Fund owns extend only to the timely payment of interest and the repayment of principal on the securities themselves and do not extend to the market value of the securities or to shares of the Fund.

Interest Rate Risk
Generally, the value of investments with interest rate risk will move in the opposite direction as movements in interest rates. When interest rates go up, the market values of previously issued money market instruments generally decline and may have an adverse effect on the Fund's ability to maintain a stable $1.00 share price. A decline in short-term interest rates or a low interest rate environment would lower the Fund's yield and the return on your investment, which may have an adverse effect on the Fund's ability to provide a positive yield to its shareholders. A zero interest rate environment may prevent the Fund from providing a positive yield to shareholders or paying the Fund's expenses out of Fund assets and could impair the Fund's ability to maintain a stable net asset value. Changes in interest rates also may change the resale value of the instruments held in the Fund's portfolio. The rate of the Fund's income will vary from day to day, generally reflecting changes in overall short-term interest rates.

Investment Risk
The Fund should not be relied upon as a complete investment program. You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

Liquidity Risk
From time to time, certain securities held by the Fund may 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 at favorable times or prices can adversely affect the Fund's ability to maintain a $1.00 share price. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. In addition, the Fund may experience difficulty satisfying redemption requests within the time periods stated in the "Redemption Policies" section of this Prospectus because of unusual market conditions, an unusually high volume of redemption requests or other reasons. Redemptions by a few large investors in the Fund at such times may have a significant adverse effect on the Fund's NAV per share and remaining Fund shareholders. In addition, the market-making capacity of dealers in certain types of securities has been reduced in recent years, in part as a result of structural and regulatory changes, such as fewer proprietary trading desks and increased regulatory capital requirements for broker-dealers. Further, many broker-dealers have reduced their inventory of certain debt securities. This could negatively affect the Fund's ability to buy or sell debt securities and increase the related volatility and trading costs. The Fund may lose money if it is forced to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Illiquid securities may be harder to value. In addition, the Fund may be subject to purchase and sale restrictions due to limitations on illiquid investments.

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 asset classes may decline in value simultaneously. In some cases, traditional market participants have been less willing to make a market in some types of debt instruments, which has affected the liquidity of those instruments. During times of market turmoil, investors tend to look to the safety of securities issued or backed by the U.S. Treasury, causing the prices of these securities to rise and the yields to decline. Reduced liquidity in fixed-income and credit markets may negatively affect many issuers worldwide. 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, particularly if markets enter a period of uncertainty or economic weakness. Periods of unusually high volatility in the financial markets and restrictive credit conditions, sometimes limited to a particular sector or geographic region, continue to recur. The value of a security may decline due to adverse issuer-specific conditions or general market conditions unrelated to a particular issuer, such as real or perceived adverse geopolitical, regulatory, market, economic or other developments that may cause broad changes in market value, changes in the general outlook for corporate earnings, changes in interest, currency or inflation rates, lack of liquidity in the markets, public perceptions concerning these developments or adverse market sentiment generally. The value of a security may also decline due to factors that affect a particular industry or industries, such as tariffs, labor shortages or increased production costs and competitive conditions within an industry. 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, which may adversely affect the value of your investment. Such market disruptions have caused, and may continue to cause, broad changes in market value, negative public perceptions concerning these developments, a reduction in the willingness and ability of some lenders to extend credit, difficulties for some borrowers in obtaining financing on attractive terms, if at all, and adverse investor sentiment or publicity. Changes in value may be temporary or may last for extended periods. Adverse market events may also lead to increased shareholder redemptions, which could cause the Fund to sell investments at an inopportune time

to meet redemption requests by shareholders and may increase the Fund's portfolio turnover, which could increase the costs that the Fund incurs and lower the Fund's performance. Even when securities markets perform well, there is no assurance that the investments held by the Fund will increase in value along with the broader market.

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 or occurrence of a federal government shutdown and threats or the occurrence of a failureto increase the federal government's debt limit,which could result in a default on the government's obligations, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations. Global economies and financial markets are becoming increasingly interconnected, which increases the possibility of many markets being affected by events in a single country or events affecting a single or small number of issuers.

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. In certain cases, an exchange or market may close or issue trading halts on either specific securities or even the entire market, which may result in the Fund being, among other things, unable to buy or sell certain securities or financial instruments or accurately price its investments. These fluctuations in securities prices could be a sustained trend or a drastic movement. 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. Deteriorating economic fundamentals may increase the risk of default or insolvency of particular issuers, negatively impact market value, increase market volatility, cause credit spreads to widen, reduce bank balance sheets and cause unexpected changes in interest rates. Any of these could cause an increase in market volatility, reduce liquidity across various sectors or markets or decrease confidence in the markets. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses.

Although interest rates were unusually low in recent years in the U.S. and abroad, in 2022, the U.S. Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. In addition, ongoing inflation pressures could continue to cause an increase in interest rates and/or negatively impact issuers. It is difficult to accurately predict the pace at which interest rates might increase or start decreasing, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or reverse course. Additionally, various economic and political factors, such as rising inflation rates, could cause the Federal Reserve or other foreign banks to change their approach in the future as such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected changes in interest rates could lead to significant market volatility or reduce liquidity in certain sectors of the market. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the prior period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. It is difficult to predict the impact on various markets of significant rate increases or other significant policy changes.

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth; the rise in protectionist trade policies; changes to international trade agreements; risks associated with the trade agreement between the United Kingdom and the European Union and the risks associated with ongoing trade negotiations with China; political or economic dysfunction within some nations, including major producers of oil; and dramatic changes in commodity and currency prices could have adverse effects that cannot be foreseen at the present time. 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 any sanctions and related events 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.

Regulators in the U.S. have proposed and recently adopted a number of changes to regulations involving the markets and issuers, some of which apply to the Fund. The full effect of various newly-adopted regulations is not currently known. Additionally, it is not clear whether the proposed regulations will be adopted. However, due to the broad scope of the new and proposed regulations, certain changes could limit the Fund's ability to pursue its investment strategies or make certain investments, or may make it more costly for the Fund to operate, which may impact performance. Further, advancements in technology may also adversely impact market movements and liquidity and may affect the overall performance of the Fund. For example, the advanced development and increased regulation of artificial intelligence may impact the economy and the performance of the Fund. As artificial intelligence is used more widely, the value of the Fund's holdings may be impacted, which could impact the overall performance of the Fund.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. There is no assurance that the U.S. Congress will act to raise the nation's debt ceiling; a failure to do so could cause market turmoil and substantial investment risks that cannot now be fully predicted. Unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy.

Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. The impact of epidemics and/or pandemics that may arise in the future could negatively affect 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 and could last for an extended period of time. China's economy, which has been sustained through debt-financed spending on housing and infrastructure, appears to be experiencing a significant slowdown and growing at a lower rate than prior years. Due to the size of China's economy, such a slowdown could impact financial markets and the broader economy.

Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Impacts from climate change may include significant risks to global financial assets and economic growth. A rise in sea levels, an increase in powerful windstorms and/or a climate-driven increase in sea levels or flooding could cause coastal properties to lose value or become unmarketable altogether. 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. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

Losses related to climate change could adversely affect, among others, corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities.

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, including, for example, advisory and administrative fees, charged by those investment companies in addition to the Fund's direct fees and expenses. The Fund must rely on the investment company in which it invests to achieve its investment objective. If the investment company fails to achieve its investment objective, the value of the Fund's investment may decline, adversely affecting the Fund's performance. 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. Although a government money market fund seeks to preserve the value of the fund's investment at $1.00 per share, at times, the share price of government money market funds may fall below the $1.00 share price, especially during periods of high redemption pressures, illiquid markets, and/or significant market volatility.

Repurchase Agreement Risk
The use of repurchase agreements involves counterparty risk and credit risk. Repurchase agreements may exhibit the economic characteristics of loans by the Fund. The obligations of a seller under the repurchase agreement are not guaranteed, and there is a risk that the seller may fail to repurchase the underlying securities, whether because of the seller's bankruptcy or otherwise. In such event, the Fund would attempt to exercise its rights with respect to the underlying collateral, including possible sale of the securities. The Fund permits various forms of securities as collateral with values that fluctuate and that are not issued or guaranteed by the U.S. government. The Fund may incur various expenses in connection with the exercise of its rights and may be subject to various delays and risks of loss, including: (a) possible declines in the value of the underlying collateral, (b) possible reduction in levels of income and (c) lack of access to the securities (if they are held through a third-party custodian) and possible inability to enforce the Fund's rights. There also are risks that a counterparty may default at a time when the collateral has declined in value, or a counterparty may become insolvent and subject to liquidation, which may affect the Fund's right to control the collateral.

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 stated interest rate and face value at maturity, not its current market price. The market prices for such securities are not guaranteed and will fluctuatewith changes in interest rates and the credit rating of the U.S. government.Additionally, circumstances could arise that would prevent the payment of interest or principal. This could result in losses to the Fund. Investments in securities issued by government-sponsored enterprises, such as Fannie Mae, Freddie Mac, FHLB, FFCB and GNMA,are debt obligations issued by agencies and instrumentalities of the U.S. government. These obligations vary in the level of support they receive from the U.S. government. They may be: (i) supported by the full faith and credit of the U.S. Treasury, such as those of GNMA; (ii) supported by the right of the issuer to borrow from the U.S. Treasury, such as those of the FHLB or the FFCB; (iii) supported by the discretionary authority of the U.S. government to purchase the agency obligations, such as those of Fannie Mae and Freddie Mac; or (iv) supported only by the credit of the issuer, such as those of the Federal Farm Credit Bureau. The U.S. government may choose not to provide financial support to U.S. government-sponsored agencies or instrumentalities if it is not legally obligated to do so, in which case, if the issuer defaulted, to the extent the Fund holds securities of such issuer, it might not be able to recover its investment from the U.S. government. U.S. government securities and securities of government-sponsored enterprisesare 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.The maximum potential liabilities of the issuers of some securities issued by the U.S. government or government-sponsored enterprises that are held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury, and it is possible that these issuers may not have the funds to meet their payment obligations in the future.

U.S. Treasury Obligations Risk
Securities issued or guaranteed by the U.S. Treasury are backed by the "full faith and credit" of the United States; however, the U.S. government guarantees the securities only as to the stated interest rate and face value at maturity, not its current market priceand the market prices of such securities may fluctuate. The market value of U.S. Treasury obligations may vary due to fluctuationsin interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the market value of theFund'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, the U.S. government's inability at times to agree on a long-term budget and deficit reduction plan, and threats not to increase the federal government's debt limit, which may result in a 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. Because U.S. Treasury securities trade actively outside the United States, their prices may also rise and fall as changes in global economic conditions affect the demand for these securities.The total public debt of the U.S. as a percent of GDP has grown rapidly in recent years. Although high debt levels do not necessarily indicate or cause economic problems, they have the potential to create systemic risks if sound debt management practices are not implemented.

Variable and Floating Rate Securities Risk
The coupons on variable and floating rate securities in which the Fund may invest are not fixed and may fluctuate based upon changes in market rates. Variable and floating rate securities are subject to interest rate risk and may fluctuate in value in response to interest rate changes if there is a delay between changes in market interest rates and the interest reset date for the obligation, or for other reasons. 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. Thus, investing in variable and floating rate instruments generally allows less opportunity for capital appreciation and depreciation than investing in instruments with a fixed interest rate. Variable and floating rate securities are less effective than fixed rate securities at locking in a particular yield and may be subject to credit risk. Certain types of floating rate instruments may also be subject to greater liquidity risk than other debt securities.

Fund Management

The Manager

AMERICAN BEACON ADVISORS, INC. (the "Manager")serves as the Manager and administrator of the Fund. The Manager, located at 220 East Las Colinas Boulevard, Suite 1200, Irving, Texas 75039, is an indirect wholly-owned subsidiary ofResolute Topco, Inc. ("Topco"), which is owned primarily by various institutional investment funds that are managed by financial institutions and other investment advisory firms. No owner of Topco owns 25% or more of the outstanding equity or voting interests of Topco.

The Manager was organized in 1986 to provide investment management, advisory, and administrative services. The Manager is registered as an investment adviser under the Advisers Act. The Manager is not registered as a CPO with respect to the Fund in reliance on the delayed compliance date provided by No-Action Letter 12-38 of the Division of Swaps Dealer and Intermediary Oversight ("Division") of the CFTC. Pursuant to this letter, the Manager is not required to register as a CPO, or rely on an exemption from registration, until six months from the date the Division issues revised guidance on the application of the calculation of the de minimis thresholds in the context of the CPO exclusion in CFTC Regulation 4.5. In addition, on behalf of the Fund, the Manager has filed a notice claiming the CFTC Regulation 4.5 exclusion from CPO registration under the Commodity Exchange Act. The Manager is also exempt from registration as a commodity trading advisor under CFTC Regulation 4.14(a)(8) with respect to the Fund.

The Fund's Management Agreement with the Manager provides for the Fund to pay the Manager an annualized management fee based on a percentage of the Fund's average daily net assets that is calculated and accrued daily equal to 0.10%. As compensation for providing management services, for the fiscal year ended December 31, 2023, the Fund paid the Manager an annualized advisory fee that is calculated and accrued daily, net of voluntary waivers of the management fees, equal to 0.10% of its average net assets. A discussion of the Board's consideration and approval of the Management Agreement between the Fund and the Manager is available in the Fund's Annual Shareholder Report dated December 31, 2023. A discussion of the Board's consideration and approval of the renewal of the Management Agreement previously in effect for the Fund is available in the Fund's Semi-Annual Shareholder Report for the period endedJune 30, 2023. The Manager may, from time to time, voluntarily waive fees and/or reimburse expenses of the Fund to the extent necessary to assist the Fund in attempting to achieve a positive yield. The Board has approved a policy whereby the Manager may seek repayment 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 the Fund to exceed the lesser of the contractual percentage limit in effect at the time of the waiver/reimbursement or the time of recoupment.

The Fund and the Manager have received an exemptive order from the SEC that permits the Fund, subject to certain conditions and approval by the Board, to hire and replace sub-advisors, and materially amend agreements with sub-advisors, that are unaffiliated with the Manager without approval of the shareholders. In the future, the Fund and the Manager may rely on an SEC staff no-action letter, dated July 9, 2019, that would permit the Fund to expand its exemptive relief to hire and replace sub-advisors that are affiliated and unaffiliated with the Manager without shareholder approval, subject to approval by the Board and other conditions. The Manager has ultimate responsibility, subject to oversight by the Board, to oversee sub-advisors and recommend their hiring, termination and replacement. The SEC order also exempts the Fund from disclosing the advisory fees paid by the Fund to individual sub-advisors in a multi-manager fund in various documents filed with the SEC and provided to shareholders. In the future, the Fund may rely on the SEC staff no-action letter to expand its exemptive relief to individual sub-advisors that are affiliated with the Manager. Under that no-action letter, the fees payable to sub-advisors unaffiliated with or partially-owned by the Manager or its parent company would be aggregated, and fees payable to sub-advisors that are wholly-owned by the Manager or its parent company, if any, would be aggregated with fees payable to the Manager. Whenever a sub-advisor change is proposed in reliance on the order, in order for the change to be implemented, the Board, including a majority of its "non-interested" trustees, must approve the change. In addition, the Fund is required to provide shareholders with certain information regarding any new sub-advisor within 90 days of the hiring of any new sub-advisor.

Valuation of Shares

The price of the Fund's shares is based on its NAV. The Fund's NAV per share is computed by adding total assets, subtracting all of the Fund's liabilities, and dividing the result by the total number of shares outstanding. Securities held by the Fund are valued in accordance with the amortized cost method, which is designed to enable the Fund to maintain a stable NAV of $1.00 per share. Neither the Fund nor the Manager provide any explicit or implicit guarantee that the Fund's NAV will always remain at $1.00 per share.

Use of Amortized Cost
Under the amortized cost valuation method, an investment is valued at its cost, adjusted for the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of the investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a "discount"), then the daily interest income accrual is increased; if the initial cost exceeds the amount payable at maturity (a "premium"), then the daily interest income accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment's cost each day. The Fund uses this adjusted cost to value the investment.

The Fund's NAV per share is typically determined as of 5:00 p.m. Eastern Time, on each day on which the NYSE is open for business. On days when the financial markets in which the Fund invests close early, the NAV per share may be calculated as of the earlier close of those markets. The Fund does not price its shares on days that the NYSE is closed. In addition to the days that the NYSE is closed, the Fund is also not open and no NAV per share is calculated on Columbus Day and Veterans Day. In certain limited circumstances, the Fund, in its discretion, may designate other days as a business day on which it will accept purchases, redemptions and exchanges.

Rule 2a-5 under the Investment Company Act establishes requirements for determining fair value in good faith for purposes of the Investment Company Act, including related oversight and reporting requirements. The rule also defines when market quotations are "readily available" for purposes of the Investment Company Act, the threshold for determining whether a Fund must fair value a security. Among other things, Rule 2a-5permits a Fund's board to designate the Fund's primary investment adviser as "valuation designee" to perform the Fund's fair value determinationssubject to board oversight and certain reporting and other requirements intended to ensure that the registered investment company's board receives the information it needs to oversee the investment adviser's fair value determinations. The Board has designated the Manager as valuation designee under the Rule 2a-5to perform fair value functions in accordance with the requirements of Rule 2a-5.

To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. When you open an account, you will be asked for information that will allow the Fund or your financial institution to identify you. Non-public corporations and other entities may be required to provide articles of incorporation, trust or partnership agreements, and taxpayer identification numbers on the account or other documentation. The Fund is required by law to reject your new account application if the required identifying information is not provided.

The Fund reserves the right to liquidate a shareholder's account at the current day's NAV per share and remit proceeds via check if the Fund or a financial institution is unable to verify the shareholder's identity within three days of account opening.

Purchase Policies

Shares of the Fund are offered and purchase orders are typically accepted until 5:00 p.m. Eastern Time on each day on which the NYSE is open for business. The Fund, at its discretion, may set earlier cutoff times due to early closures in the bond markets or the NYSE. In addition, the Fund may, in its discretion, accept orders on days when the NYSE is closed. Shares of the Fund are not offered and orders are not accepted on Columbus Day and Veterans Day.

If a purchase order is received by the Fund in good order prior to the Fund's deadline, the purchase price will be the NAV per share next determined on that day. A purchase order is considered to be received in good order when it complies with all of the Fund's applicable policies. If a purchase order is received in good order after the applicable deadline, the purchase price will be the NAV per share of the following day that the Fund is open for business. The Fund has the right to reject any purchase order or cease offering shares at any time. No sales charges are assessed on the purchase or sale of Fund shares.

Shares of the Fund will only be issued against full payment, as described more fully in this Prospectus. Fund shares may be purchased only in U.S. States and Territories in which they can be legally sold.

The Fund reserves the right to refuse purchases if, in the judgment of the Fund, the transaction would adversely affect the Fund and its shareholders. The Fund reserves the right to require payment by wire.

The Fund has authorized certain third-party financial intermediaries, such as broker-dealers, insurance companies, third party administrators and trust companies, to receive purchase and redemption orders on behalf of the Fund and to designate other intermediaries to receive purchase and redemption orders on behalf of the Fund. The Fund is deemed to have received such orders when they are received by the financial intermediaries or their designees. Thus, an order to purchase or sell Fund shares will be priced at the Fund's next determined NAV per share after receipt by the financial intermediary or its designee. You should contact your broker-dealer or other financial intermediary to find out by what time your purchase order must be received so that it can be processed the same day. It is the responsibility of your broker-dealer or financial intermediary to transmit orders that will be received by the Fund in proper form and in a timely manner. The Fund is not responsible for the failure of a broker-dealer or financial intermediary to transmit a purchase order in proper form and in a timely manner.

The Fund has the right to reject any purchase order or cease offering shares at any time.

Additionally, the Board may, in its discretion, permanently suspend redemptions and liquidate if, among other things, the Fundat the end of a business dayhas less than 10% of its total assets invested in weekly liquid assets. The Board may also permanently suspend redemptions and liquidate the Fund if the Board determines that the deviation between its amortized cost price per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders.

Although the Fund intends to redeem shares by paying out available cash, cash generated by selling portfolio holdings (including cash equivalent portfolio holdings), or funds borrowed through the interfund credit facility, or from a bank line of credit, in stressed market conditions and other appropriate circumstances, the Fund reserves the right to pay the redemption price in whole or in part by borrowing funds from external parties or distributing securities or other assets held by the Fund. To the extent that the Fund redeems its shares in this manner, the shareholder assumes the risk of a subsequent change in the market value of those securities, the cost of liquidating the securities and the possibility of a lack of a liquid market for those securities. Unpaid dividends credited to an account up to the date of redemption of all shares of the Fund generally will be paid at the time of redemption.

Supporting documents may be required for redemptions by estates, trusts, guardianships, custodians, corporations, and welfare, pension and profit sharing plans. Redemption requests must also include authorized signature(s) of all persons required to sign for the account. Call 1-800-658-5811 for instructions.

■	Proceeds will be mailed to the account address of record or transmitted to the commercial bank designated on the account application form.

To protect the Fund and your account from fraud, a Medallion signature guarantee is required for redemption orders:

■	with a request to send the proceeds to an address or commercial bank account other than the address or commercial bank account designated on the account application, or

■	for an account whose address has changed within the last 30 days if proceeds are sent by check.

The Fund only accepts Medallion signature guarantees, which may be obtained at participating banks, broker-dealers and credit unions. A notary public cannot provide a signature guarantee. Call 1-800-658-5811 for instructions and further assistance.

Payments to Financial Intermediaries

The Fund and/or the Manager (and/or the Manager's affiliates) (at their own expense) may pay compensation to financial intermediaries for shareholder-related services and, if applicable, distribution-related services, including administrative, sub-transfer agency type, recordkeeping and shareholder communication services. For example, compensation may be paid to make Fund shares available to sales representatives and/or customers of a fund supermarket platform or similar program sponsor or for services provided in connection with such fund supermarket platforms and programs.

The amount of compensation paid to different financial intermediaries may differ. The compensation paid to a financial intermediary may be based on a variety of factors, including average assets under management in accounts distributed and/or serviced by the financial intermediary, gross sales by the financial intermediary and/or the number of accounts serviced by the financial intermediary that invest in the Fund. To the extent that the Fund pays any such compensation, it is designed to compensate the financial intermediary for providing services that would otherwise be provided by the Manager, the Fund or its transfer agent. To the extent the Manager or its affiliate pays such compensation, it would likely include amounts from that party's own resources and constitute what is sometimes referred to as "revenue sharing."

Compensation received by a financial intermediary from the Fund, the Manager or an affiliate of the Manager may include payments for marketing and/or training expenses incurred by the financial intermediary, including expenses incurred by the financial intermediary in educating (itself and) its salespersons with respect to Fund shares. For example, such compensation may include reimbursements for expenses incurred in attending educational seminars regarding the Fund, including travel and lodging expenses. It may also cover costs incurred by financial intermediaries in connection with their efforts to sell Fund shares, including costs incurred compensating (registered) sales representatives and preparing, printing and distributing sales literature.

Any compensation received by a financial intermediary, whether from the Fund or the Manager and/or its affiliate(s), and the prospect of receiving it may provide the financial intermediary with an incentive to recommend the shares of the Fund over other potential investments. Similarly, the compensation may cause financial intermediaries to elevate the prominence of the Fund within its organization by, for example, placing it on a list of preferred funds. You can contact your financial intermediary for details about any such payments it receives from the Manager, its affiliates and/or the Fund, or any other fees, expenses, or commissions your financial intermediary may charge you in addition to those disclosed in this Prospectus.

General Policies

If a shareholder's account balance falls below $250,000, the shareholder may be asked to increase the balance.

If the account balance remains below $250,000 after 45 days, the Fund reserves the right, upon 30 days' advance written notice, to close the account and send the proceeds to the shareholder. The Fund reserves the authority to modify minimum account balances in its discretion.

An ACH privilege allows electronic transfer from a checking or savings account into a direct account with the Fund. The ACH privilege may not be used for initial purchases but may be used for subsequent purchases and redemptions. Purchases of Fund shares by ACH are subject to a limit of $2,000 per day. The Fund reserves the right to waive such limit in its sole discretion.

ACH privileges must be requested on the account application, or may be established on an existing account by submitting a request in writing to the Fund. Validated signatures from all shareholders of record for the account are required on the written request. See details below regarding signature validations. Such privileges apply unless and until the Fund receives written instructions from all shareholders of record canceling such privileges. Changes of bank account information must also be made in writing with validated signatures. The Fund reserves the right to amend, suspend or discontinue the ACH privilege at any time without prior notice. The ACH privilege does not apply to shares held in broker "street name" accounts or in other omnibus accounts.

When a signature validation is called for, a Medallion signature guarantee or SVP stamp may be required. A Medallion signature guarantee is intended to provide signature validation for transactions considered financial in nature, and an SVP stamp is intended to provide signature validation for transactions non-financial in nature. A Medallion signature guarantee or SVP stamp may be obtained from a domestic bank or trust company, broker, dealer, clearing agency, savings association or other financial institution which is participating in a Medallion program or SVP recognized by the Securities Transfer Association. The Fund may reject a Medallion signature guarantee or SVP stamp. Shareholders should call 800-658-5811 for additional details regarding the Fund's signature guarantee requirements.

The Fund reserves the right to:

■	liquidate a shareholder's account at the current day's NAV per share and remit proceeds via check if the Fund or a financial institution are unable to verify the shareholder's identity within three business days of account opening,

■	seek reimbursement from the shareholder for any related loss incurred by the Fund if payment for the purchase of Fund shares by check does not clear the shareholder's bank, and

■	reject a purchase order and seek reimbursement from the shareholder for any related loss incurred by the Fund if funds are not received by the applicable wire deadline.

The following policies apply to instructions you may provide to the Fund by telephone:

■	The Fund, its officers, trustees, employees, or agents are not responsible for the authenticity of instructions provided by telephone, nor for any loss, liability, cost or expense incurred for acting on them.

■	The Fund employs procedures reasonably designed to confirm that instructions communicated by telephone are genuine.

Prospectus- About Your Investment11

■	Due to the volume of calls or other unusual circumstances, telephone redemptions may be difficult to implement during certain time periods.

Escheatment

Please be advised that certain state escheatment laws may require the Fund to turn over your mutual fund account to the state listed in your account registration as abandoned property unless you contact the Fund. Many states have added ''inactivity'' or the absence of customer initiated contactas a component of their rules and guidelines for the escheatment of unclaimed property. These states consider property to be abandoned when there is no shareholder initiated activityon an account for at least three (3) to five (5) years.

Depending on the laws in your jurisdiction, customer initiated contact might be achieved by one of the following methods:

■	Send a letter to American Beacon Select Funds via the United States Post Office,

■	Speak to a Customer Service Representative on the phone after you go through a security verification process. For residents of certain states, contact cannot be made by phone but must be in writing or through the Fund's secure web application.

■	Access your account through the Fund's secure web application,

■	Cashing checks that are received and are made payable to the owner of the account.

The Fund, the Manager, and the Transfer Agent will not be liable to shareholders or their representatives for good faith compliance with escheatment laws. To learn more about the escheatment rules for your particular state, please contact your attorney or State Treasurer's and/or Controller's Offices. Unless you hold your shares directly with the Fund, you should contact your broker-dealer, retirement plan, or other third party, intermediary regarding applicable state escheatment laws.

Shareholders that reside in the state of Texas may designate a representative to receive escheatment notifications by completing and submitting a designation form that can be found on the website of the Texas Comptroller. While the designated representative does not have any rights to claim or access the shareholder's account or assets, the escheatment period will cease if the representative communicates knowledge of the shareholder's location and confirms that the shareholder has not abandoned his or her property. If a shareholder designates a representative to receive escheatment notifications, any escheatment notices will be delivered both to the shareholder and the designated representative. The completed designation form may be mailed to the below address.

Frequent Trading

The Fund is intended to serve as a short-term investment vehicle providing daily liquidity to shareholders. As such, the Fund's Board of Trustees has determined not to adopt policies to deter short-term trading of Fund shares. The Manager attempts to maintain sufficient liquidity for the Fund to satisfy redemption requests. In the event of large net redemptions, due to frequent trading activity or other circumstances, the Manager may be required to sell portfolio securities before maturity, possibly causing the Fund to underperform other similar money market funds.

Distributions and Taxes

The Fund distributes most or all of its net earnings in the form of dividends from net investment income, which are declared daily and paid monthly, and distributions of realized net short-term capital gains, if any (collectively, "Distributions"). Distributions are taxable as ordinary income. None of the Fund's distributions is expected to be eligible for the dividends-received deduction available to corporations; however, the portion of the Fund's Distributions derived from interest on certain direct U.S. Government obligations is generally exempt from state and local income taxes. Unless your account application instructs otherwise, Distributions will be reinvested in additional Fund shares. Distributions declared in each month are paid to shareholders on the first business day of the following month.

If you invest directly with the Fund, any election to receive Distributions payable by check will only apply to Distributions totaling $10.00 or more. Any Distribution totaling less than $10.00 will be reinvested in Fund shares and will not be paid to you by check.

If you elect to receive a Distribution by check and the U.S. Postal Service cannot deliver your check, or if your check remains uncashed for six months, the Fund reserves the right to reinvest the amount of your check, and to reinvest all subsequent Distributions, in shares of the Fund at the NAV per share on the day of the reinvestment. Interest will not accrue on amounts represented by uncashed Distribution or redemption checks.

Shareholders investing in the Fund through a financial intermediary should discuss their options for receiving Distributions with their financial advisor.

You will not recognize any gain or loss on the redemption or exchange of Fund shares so long as the Fund maintains a stable share price of $1.00.

The foregoing is only a summary of some of the important federal income tax considerations that may affect Fund shareholders, who should consult their tax advisers regarding specific questions as to the effect of federal, state and local income taxes on an investment in the Fund. Each year, the Fund's shareholders will receive tax information to assist them in preparing their income tax returns.

ORGANIZATION AND HISTORY OF THE FUND

The American Beacon U.S. Government Money Market Select Fund (the "Fund") is a series of the American Beacon Select Funds (the "Trust"), an open-end, diversified management investment company organized as a Massachusetts business trust on August 18, 1999. The Fund constitutes a separate investment portfolio with a distinct investment objective and distinct purpose and strategy.

ADDITIONAL INFORMATION ABOUT INVESTMENT STRATEGIES AND RISKS

The investment objective, principal investment strategies and principal risks ofthe Fund are described in the Prospectus. This section contains additional information about the Fund's investment policies and risks and types of investmentsthe Fund may purchase. The composition ofthe Fund's portfolio and the strategiesthat the Fund may use in selecting investments may vary over time.The Fund is not required to use all of the investment strategies described below in pursuing its investment objective. It may use some of the investment strategies only at some times or it may not use them at all. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund.

Borrowing Risk- The Fund may borrow money in an amount up to one-third of its total assets (including the amount borrowed) from banks and other financial institutions. The Fund may borrow for temporary purposes. Borrowing may exaggerate changes in the Fund's NAV and in its total return. Interest expense and other fees associated with borrowing may impact the Fund's expenses and reduce its returns.

Callable Securities- 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. Thus, the Fund's income could be reduced as a result of a call. In addition, the market value of a callable security may decrease if it is perceived by the market as likely to be called, which could have a negative impact on the Fund's total return.

Cash Equivalents and Other Short-Term Investments- Cash equivalents and other short-term investments in which the Fund may invest include the investments set forth below. Certain of these investments are issued by and provide exposure to banks. The activities of U.S. banks and most foreign banks are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operations and profitability of domestic and foreign banks. Significant developments in the U.S. banking industry have included increased competition from other types of financial institutions, increased acquisition activity and geographic expansion. Banks may be particularly susceptible to certain economic factors, such as interest rate changes and adverse developments in the market for real estate. Fiscal and monetary policy and general economic cycles can affect the availability and cost of funds, loan demand and asset quality and thereby impact the earnings and financial conditions of banks.

■

Bank Deposit Notes.Bank deposit notes are obligations of a bank that provide an alternative to certificates of deposit. Similar to certificates of deposit, deposit notes represent bank level investment and, therefore, are senior to all holding company corporate debt. Bank deposit notes rank junior to domestic deposit liabilities of the bank and pari passu with other senior, unsecured obligations of the bank. Typically, bank deposit notes are not insured by the Federal Deposit Insurance Corporation or any other insurer.

■

Bankers' Acceptances.Bankers' acceptances are short-term credit instruments designed to enable businesses to obtain funds to finance commercial transactions. Generally, an acceptance is a time draft drawn on a bank by an exporter or an importer to obtain a stated amount of funds to pay for specific merchandise. The draft is then "accepted" by a bank that, in effect, unconditionally guarantees to pay the face value of the instrument on its maturity date. The acceptance may then be held by the accepting bank as an earning asset or it may be sold in the secondary market at the going rate of discount for a specific maturity. Most acceptances have maturities of six months or less. Bankers' acceptances rank junior to domestic deposit liabilities of the bank and pari passu with other senior, unsecured obligations of the bank.

■

CDs.CDs are negotiable certificates issued against funds deposited in an eligible bank (including its domestic and foreign branches, subsidiaries and agencies) for a definite period of time and earning a specified rate of return. U.S. dollar denominated CDs issued by banks abroad are known as Eurodollar CDs. CDs issued by foreign branches of U.S. banks are known as Yankee CDs.

■

Commercial Paper.Commercial paper refers to promissory notes representing an unsecured debt of a corporation or other entity, usually for purposes such as financing current operations, and with a fixed maturity, typically, within 270 days. The commercial paper purchased by the Fund consists of direct U.S. dollar-denominated obligations of domestic or foreign issuers. The Fund may invest in commercial paper that is not registered under the Securities Act of 1933, as amended ("Securities Act"), but is instead issued in reliance on the private placement exemption from registration afforded by Section 4(a)(2) of the Securities Act ("Section 4(a)(2) paper"). The Fund also may invest in commercial paper that can be offered and sold only to "qualified institutional buyers" pursuant to Rule 144A of the Securities Act ("Rule 144A securities"). Section 4(a)(2) paper is restricted as to disposition under the federal securities laws and generally is sold to institutional investors that agree that they are purchasing the paper for investment and not with a view to public distribution. Any resale by the purchaser must be a transaction exempt from the registration requirements of the Securities Act. Section 4(a)(2) paper normally is resold to other institutional investors like the Fund through or with the assistance of the issuer or investment dealers that make a market in Section 4(a)(2) paper. Rule 144A securities generally must be sold only to other qualified institutional buyers. Section 4(a)(2) paper and Rule 144A securities will not be considered illiquid for purposes of the Fund's percentage limitations on illiquid securities when the Manager determines that a liquid trading market exists for the securities in question. There can be no assurance that a liquid trading market will exist at any time for any particular Section 4(a)(2) paper or Rule 144A securities.

■

Eurodollar and Yankee CD Obligations.Eurodollar obligations are U.S. dollar obligations issued outside the United States by domestic or foreign entities, while Yankee CDs are U.S. dollar obligations issued inside the United States by foreign entities. There is generally less publicly available information about foreign issuers and there may be less governmental regulation and supervision of foreign stock exchanges, brokers and listed companies. Foreign issuers may use different accounting and financial standards, and the addition of foreign governmental restrictions may affect adversely the payment of principal and interest on foreign investments. In addition, not all foreign branches of United States banks are supervised or examined by regulatory authorities as are United States banks, and such branches may not be subject to reserve requirements. Eurodollar (and, to a

Back to Table of Contents

limited extent, Yankee dollar) obligations are subject to certain sovereign risks. One such risk is the possibility that a sovereign country might prevent capital, in the form of dollars, from flowing across its borders. Other risks include adverse political and economic developments; the extent and quality of government regulation of financial markets and institutions; the imposition of foreign withholding taxes; and the expropriation or nationalization of foreign issuers.

■

Government Money Market Funds.The Fund may invest cash balances in money market funds that are registered as investment companies under the Investment Company Act. Money market funds invest in highly-liquid, short-term instruments, which include cash and cash equivalents, and debt securities with high credit ratings and short-term maturities, such as U.S. Treasuries. A "government money market fund" is required to invest at least 99.5% of its total assets in cash, U.S. government securities, and/or repurchase agreements that are fully collateralized by government securities or cash. Government securities include any security issued or guaranteed as to principal or interest by the U.S. government and its agencies or instrumentalities. By investing in a government money market fund, the Fund becomes a shareholder of that fund. As a result, Fund shareholders indirectly bear their proportionate share of the expenses of the government money market funds in which the Fund invests in addition to any fees and expenses Fund shareholders directly bear in connection with the Fund's own operations. These expenses may include, for example, advisory and administrative fees. A government money market fund may impose a fee upon sale of its shares at the determination of its board, which could increase the Fund's expenses. These other fees and expenses are reflected in the Fees and Expenses Table for the Fund in its Prospectus, if applicable. Shareholders also would be exposed to the risks associated with government money market funds and the portfolio investments of such funds, including that a government money market fund's yield will be lower than the return that the Fund would have derived from other investments that would provide liquidity. Although a government money market fund is designed to be a relatively low risk investment, it is not free of risk. Despite the short maturities and high credit quality of a government money market fund's investments, increases in interest rates and deteriorations in the credit quality of the instruments the government money market fund has purchased can cause the price of a government money market security to decrease and may reduce the government money market fund's yield. In addition, a government money market fund is subject to the risk that the value of an investment may be eroded over time by inflation. Factors that could adversely affect the value of a government money market fund's shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the government money market fund, a high volume of redemption activity in a government money market fund's shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the government money market fund. There can be no assurance that a government money market fund will maintain a $1.00 per share net asset value ("NAV") at all times. The failure of an unrelated government money market fund to maintain a stable NAV could create a widespread risk of increased redemption pressures on all government money market funds, potentially jeopardizing the stability of their NAVs. Government money market funds are not requiredto impose liquidity fees, while other types of money market funds may be required to impose liquidity fees under certain conditions. However, government money market funds typically offer materially lower yields than other money market funds. Government moneymarket funds and the securities they invest in are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of government money market funds. In 2024,amendments to the regulation of governmentmoney market funds increaseddaily and weekly liquid asset requirements, removed temporaryredemption gate provisions and required prospectus disclosure if a fund intends to cancel shares in response to a negative interest rate environment. There can be no assurance that the Fund's investments in government money market funds willnot be adversely affected by these or other reforms to existing rules or new regulationsthat may be adopted by the SEC or other regulatory authorities. An investment in a government money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency.

■	Government Obligations.Government obligations may include U.S. Treasury securities, Treasury inflation-protected securities, and other debt instruments backed by the full faith and credit of the United States, or debt obligations of U.S. Government-sponsored entities.

■

Money Market Funds. The Fund may invest cash balances in money market funds that are registered as investment companies under the Investment Company Act. Money market funds invest in highly-liquid, short-term instruments, which include cash and cash equivalents, and debt securities with high credit ratings and short-term maturities, such as U.S. Treasuries. If the Fund invests in money market funds, shareholders will bear their proportionate share of the expenses of the money market funds in which the Fund invests. These expenses may include, for example, advisory and administrative fees. Shareholders also would be exposed to the risks associated with money market funds and the portfolio investments of such money market funds, including that a money market fund's yield will be lower than the return that the Fund would have derived from other investments that would provide liquidity.

■

Repurchase Agreements.Repurchase agreements are agreements pursuant to which the Fund purchases securities from a bank that is a member of the Federal Reserve System (or a foreign bank or U.S. branch or agency of a foreign bank), or from a securities dealer, that agrees to repurchase the securities from the Fund at a higher price on a designated future date. Repurchase agreements generally are for a short period of time, usually less than a week. Costs, delays, or losses could result if the selling party to a repurchase agreement becomes bankrupt or otherwise defaults.

■	Short-term Corporate Debt Securities.Short-term corporate debt securities are securities and bonds issued by corporations with shorter terms to maturity. Corporate securities generally bear a higher risk than U.S. government bonds.

■

Time Deposits.Time deposits, also referred to as "fixed time deposits," are non-negotiable deposits maintained at a banking institution for a specified period of time at a specified interest rate. Time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties which vary depending upon market conditions and the remaining maturity of the obligation. There are no contractual restrictions on the right to transfer a beneficial interest in a time deposit to a third party, although there is no market for such deposits.

Corporate Actions- From time to time, the Fund may voluntarily participate in corporate actions (for example, acquisitions, mergers, rights offerings, conversion privileges, exchange offers, credit event settlements, etc.) where the issuer or counterparty offers securities or instruments to holders or counterparties, such as the Fund, and the acquisition is determined to be beneficial to Fund shareholders ("Corporate Actions"). Notwithstanding any percentage investment limitation listed under the "Investment Restrictions" section or any percentage investment limitation of the Investment Company Act or rules thereunder, if the Fund has the opportunity to acquire a permitted security or instrument through a Corporate Action, and by doing so, the Fund would exceed a percentage investment limitation following the acquisition, it will not constitute a violation if, prior

to the receipt of the securities or instruments and after announcement of the Corporate Action, the Fund sells an offsetting amount of assets that are subject to the investment limitation in question at least equal to the value of the securities or instruments to be acquired.

Cybersecurity and Operational Risk - With the increased use of technologies such as the Internet and the dependence on computer systems to perform necessary business functions, the Fund, and its service providers, may be prone to operational and information security risks resulting from cyber-attacks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber-attacks include, but are not limited to, stealing or corrupting data maintained online or digitally (e.g., through "hacking," computer viruses or other malicious software coding), the theft and holding for ransom of proprietary or confidential information or data (sometimes referred to as "ransomware" attacks), denial of service attacks on websites, "phishing" attempts and other social engineering techniques aimed at personnel or systems, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund or the Manager, the Custodian (as defined below), the transfer agent, intermediaries and other third-party service providers may adversely impact the Fund. For instance, cyber-attacks may interfere with the processing of shareholder transactions, result in the loss or theft of shareholder data or funds, impact the Fund's ability to calculate NAV per share, cause the release of private shareholder information or confidential business information, impede trading, subject the Fund to regulatory fines or financial losses and/or cause reputational damage. A cyber-attack may also result in shareholders or service providers being unable to access electronic systems ("denial of services"), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. The Fund may also incur additional costs for cybersecurity risk management purposes. Similar types of cybersecurity risks are also present for issuers or securities in which the Fund may invest, which could result in material adverse consequences for such issuers and may cause the Fund's investment in such companies to lose value. Adverse consequences also could result from cybersecurity incidents affecting counterparties with which the Fund engages in transactions, governmental and other regulatory authorities, exchanges and other financial market operators, banks, brokers, dealers, insurance companies, other financial institutions and other parties. The Fund's service providers also may be negatively impacted due to operational risks arising from non-cybersecurity related factors such as processing errors and human errors, inadequate or failed internal or external processes, failures in systems and technology errors or malfunctions, changes in personnel, and errors caused by Fund service providers or counterparties.

In addition, other events or circumstances - whether foreseeable, unforeseeable, or beyond our control, such as acts of war, other conflicts, terrorism, natural disaster, widespread disease, pandemic or other public health crises may result in, among other things, quarantines and travel restrictions, workforce displacement and loss or reduction in Personnel and other resources. In the above circumstances, the Fund and the Service Providers' operations may be significantly impacted, or even temporarily halted. The Fund's securities market counterparties or vendors may face the same or similar systems failure, cybersecurity breaches and other business disruptions risks.

Any of these results could have a substantial adverse impact on the Fund and its shareholders. For example, if a cybersecurity incident results in a denial of service, Fund shareholders could lose access to their electronic accounts and be unable to buy or sell Fund shares for an unknown period of time, and service providers could be unable to access electronic systems to perform critical duties for the Fund, such as trading, NAV calculation, shareholder accounting or fulfillment of Fund share purchases and redemptions. Cybersecurity incidents could cause the Fund or a service provider to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures, or financial loss of a significant magnitude and could result in allegations that the Fund or Fund service provider violated privacy and other laws. There are inherent limitations in risk management systems that seek to reduce the risks associated with cybersecurity and business continuity plans in the event there is a cybersecurity breach, including the possibility that certain risks may not have been adequately identified or prepared for, in large part because different or unknown threats may emerge in the future. Furthermore, the Fund does not control the cybersecurity systems and plans of the issuers of securities in which the Fund invests, third party service providers, trading counterparties or any other service providers whose operations may affect the Fund or its shareholders. The widespread use of work-from-home arrangements, such as during the COVID-19 pandemic, may increase operational and information security risks.

Debentures- Debentures are unsecured, medium- to long-term debt securities protected only by the general creditworthiness of the corporate or government issuer, not by collateral, and documented by indentures. Governments often issue debentures because they generally cannot guarantee debt with assets due to the fact that government assets are public property. Debenture holders are unsecured creditors. In the event of default or bankruptcy by the issuer, debenture holders will not have a claim against any specific assets of the issuer and will therefore only be paid from the issuer's assets after the secured creditors have been paid. The value of a debenture can fluctuate with changes in interest rates and the perceived ability of the issuer to make interest or principal payments on time.

Expense Risk- Fund expenses are subject to a variety of factors, including fluctuations in the Fund's net assets. Accordingly, actual expenses may be greater or less than those indicated. For example, to the extent that the Fund's net assets decrease due to market declines or redemptions, the Fund's expenses will increase as a percentage of Fund net assets. During periods of high market volatility, these increases in the Fund's expense ratio could be significant.

Fixed-Income Investments- The Fund may hold debt instruments, including government and corporate debt instruments, and other fixed-income securities, including derivative instruments that have fixed-income securities as reference assets. Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that their value will generally decline as prevailing interest rates rise, which may cause the Fund's NAV to likewise decrease, and vice versa. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. For example, while securities with longer maturities tend to produce higher yields, they also tend to be more sensitive to changes in prevailing interest rates and are therefore more volatile than shorter-term securities and are subject to greater market fluctuations as a result of changes in interest rates. However, calculations of maturity and duration may be based on estimates and may not reliably predict a security's price sensitivity to changes in interest rates. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and non-U.S. interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. Investments in fixed-income securities with very low or negative interest rates may diminish the Fund's yield and performance. Conversely, if rising interest rates cause the Fund to lose value, the Fund could face increased shareholder redemptions, which may lead to increased portfolio turnover and transaction costs. An increase in shareholder redemptions could also force the Fund to liquidate investments at disadvantageous times or prices, therefore adversely affecting the Fund as well as the value of your investment. For fixed-income securities with variable or floating rates, the interest rates reset when the specified index or reference rate

changes. Fixed-income securities are also subject to credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable or unwilling to make timely principal and interest payments and that the security may go into default. In addition, there is prepayment risk, which is the risk that during periods of falling interest rates, certain fixed-income securities with higher interest rates, such as mortgage- and asset-backed securities, may be prepaid by their issuers thereby reducing the amount of interest payments. This is similar to call risk, which is the risk that the issuer of a debt security may repay the security early. This may result in the Fund not enjoying the increase in the security's market price that usually accompanies a decline in rates, and also having to reinvest its proceeds in lower yielding securities. Fixed-income securities may also be subject to valuation risk and liquidity risk. Valuation risk is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security's sale. In times of market instability, valuation may be more difficult. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that the Fund would like or at the price the Manager believes the security is currently worth. To the extent the Fund invests in fixed-income securities in a particular industry or economic sector, its share values may fluctuate in response to events affecting that industry or sector.

Securities underlying mortgage- and asset-backed securities, which may include subprime mortgages, also may be subject to a higher degree of credit risk, valuation risk, and liquidity risk. To the extent that the Fund invests in derivatives tied to fixed-income securities, such Fund may be more substantially exposed to these risks than a portfolio that does not invest in such derivatives.

Fixed-income securities are also subject to market risk. The market for certain fixed-income securities may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Recent and potential future changes in government monetary policy may also affect the level of interest rates. The Fund may be subject to heightened interest rate risk in times of monetary policy change and uncertainty, such as when the Federal Reserve ends a quantitative easing program and/or raises interest rates. The end of quantitative easing and/or rising interest rates may expose fixed-income markets to increased volatility and may reduce the liquidity of certain investments. These developments could cause the Fund's NAV to fluctuate or make it more difficult for the Fund to accurately value its securities. The amount of assets deemed illiquid remaining within the Fund may also increase, making it more difficult to meet shareholder redemptions and further adversely affecting the value of the Fund.

In addition, specific types of fixed-income securities in which the Fund may invest are subject to the risks described elsewhere in this SAI.

■

Corporate Debt and Other Fixed-Income Securities.Typically, the values of fixed income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed income securities is interest rate risk, which is the risk that their value generally will decline as prevailing interest rates rise, which may cause the Fund's NAV to likewise decrease, and vice versa. How specific fixed income securities may react to changes in interest rates will depend on the specific characteristics of each security. For example, while securities with longer maturities tend to produce higher yields, they also tend to be more sensitive to changes in prevailing interest rates. They are therefore more volatile than shorter-term securities and are subject to greater market fluctuations as a result of changes in interest rates. Fixed income securities are also subject to credit risk, which is the risk that the credit strength of an issuer of a fixed income security will weaken and/or that the issuer will be unable to make timely principal and interest payments, and that the security may go into default.

Illiquid and Restricted Securities- Generally, an illiquid asset is an asset that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Historically, illiquid securities have included securities that have not been registered under the Securities Act, securities that are otherwise not readily marketable, and repurchase agreements having a remaining maturity of longer than seven calendar days.

Securities that have not been registered under the Securities Act are referred to as private placements or restricted securities and are purchased directly from the issuer or in the secondary market. Such securities include those sold in private placement offerings made in reliance on the "private placement" exemption from registration afforded by Section 4(a)(2) of the Securities Act, and resold to qualified institutional buyers pursuant to Rule 144A under the Securities Act ("Section 4(a)(2) securities"). Such securities are restricted as to disposition under the federal securities laws, and generally are sold to institutional investors, such as the Fund, that agree they are purchasing the securities for investment and not with an intention to distribute to the public. These securities may be sold only in a privately negotiated transaction or pursuant to an exemption from registration.

A large institutional market exists for certain securities that are not registered under the Securities Act, including repurchase agreements, commercial paper, foreign securities, municipal securities and corporate bonds and notes. Section 4(a)(2) securities normally are resold to other institutional investors through or with the assistance of the issuer or dealers that make a market in the Section 4(a)(2) securities, thus providing liquidity. Institutional investors depend on an efficient institutional market in which the unregistered security can be readily resold or on an issuer's ability to honor a demand for repayment. Rule 144A under the Securities Act is designed to facilitate efficient trading among institutional investors by permitting the sale of certain unregistered securities to qualified institutional buyers. To the extent privately placed securities held by the Fund qualify under Rule 144A and an institutional market develops for those securities, the Fund likely will be able to dispose of the securities without registering them under the Securities Act. To the extent that institutional buyers are uninterested in purchasing restricted securities, the Fund's investment in such securities could have the effect of reducing the Fund's liquidity. A determination could be made that certain securities qualified for trading under Rule 144A are liquid. In addition to Rule 144A, Regulation S under the Securities Act permits the sale abroad of securities that are not registered for sale in the United States and includes a provision for U.S. investors, such as the Fund, to purchase such unregistered securities if certain conditions are met.

Limitations on resale may have an adverse effect on the marketability of portfolio securities, and the Fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven calendar days. However, the fact that there are contractual or legal restrictions on resale of such investments to the general public or to certain institutions may not be indicative of their liquidity. In addition, the Fund may get only limited information about an issuer of such a security, so it may be less able to predict a loss. The Fund also might have to register such restricted securities in order to dispose of them, resulting in additional expense and delay. Adverse market conditions could impede such a public offering of securities. The illiquidity of the market, as well as the lack of publicly available information regarding these securities, also may make it difficult to determine a fair value for certain securities for purposes of computing the Fund's NAV.

Issuer Risk- The value of an investment may decline for a number of reasons which 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.

Redemption Risk- The Fund may experience periods of heavy redemptions that could cause the Fund to sell assets at inopportune times at a loss or depressed value. The risk of loss is greater if redemption requests are frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to sell are illiquid. The sale of assets to meet redemption requests may create capital gains, which the Fund would then be required to distribute to shareholders. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund, have short investment horizons, or have unpredictable cash flow needs. Additionally, during periods of heavy redemptions, the Fund may borrow funds from the interfund credit facility, or from a bank line of credit, which may increase costs. The ability or willingness of dealers and other institutional investors to buy or hold fixed-income securities or otherwise to "make a market" in debt securities has also been reduced. Heavy redemptions, whether by a few large investors or many smaller investors, could hurt the Fund's performance.

Repurchase Agreements- A repurchase agreement is an agreement between the Fund as purchaser and an approved counterparty as seller. The agreement is backed by collateral in the form of securities and/or cash transferred by the seller to the buyer, sometimes to be held by an eligible third-party custodian. Under the agreement, the Fund acquires securities from the seller and the seller simultaneously commits to repurchase the securities at an agreed upon price and date, normally within a week or on demand. The price for the seller to repurchase the securities is greater than the Fund's purchase price, reflecting an agreed upon rate that is the equivalent of interest. During the term of the repurchase agreement, the Fund monitors on a daily basis the market value of the collateral subject to the agreement and, if the market value of the securities falls below the seller's repurchase amount provided under the repurchase agreement, the seller is required to transfer additional securities or cash collateral equal to the amount by which the market value of the securities falls below the repurchase amount. Because a repurchase agreement permits the Fund to invest temporarily available cash on a fully-collateralized basis, repurchase agreements permit the Fund to earn income while retaining flexibility in pursuit of longer-term investments. Repurchase agreements may exhibit the economic characteristics of loans by the Fund.

The obligation of the seller under the repurchase agreement is not guaranteed, and there is a risk that the seller may fail to repurchase the underlying securities, whether because of the seller's bankruptcy or otherwise. In such event, the Fund would attempt to exercise its rights with respect to the underlying collateral, including possible sale of the securities. The Fund may incur various expenses in the connection with the exercise of its rights and may be subject to various delays and risks of loss, including (a) possible declines in the value of the underlying collateral, (b) possible reduction in levels of income and (c) lack of access to the securities (if they are held through a third-party custodian) and possible inability to enforce the Fund's rights. The Board has established procedures pursuant to which the Manager monitors the creditworthiness of the counterparties with which the Fund enters into repurchase agreement transactions.

The Fund may enter into repurchase agreements with member banks of the Federal Reserve System or registered broker-dealers who, in the opinion of the Manager, present a minimal risk of default during the term of the agreement. The underlying securities which serve as collateral for repurchase agreements may include fixed income and equity securities such as U.S. Government and agency securities, municipal obligations, corporate obligations, asset-backed securities, mortgage-backed securities, common and preferred stock, depositary receipts, ETFs, corporate obligations and convertible securities.

Repurchase agreements that are collateralized fully may be deemed to be an acquisition of the underlying collateral (i.e. cash and/or Government Securities) and thus allow the Fund to have exposure to the seller that exceeds the typical issuer limit under Rule 2a-7.

Supranational Risk- Supranational organizations are entities designated or supported by a government or governmental group to promote economic development. Supranational organizations have no taxing authority and are dependent on their members for initial and ongoing payments of interest and principal to the extent their assets are insufficient. Further, the lending activities of such entities are limited to a percentage of their total capital, reserves and net income. Obligations of supranational entities are subject to the risk that the governments on whose support the entity depends for its financial backing or repayment may be unable or unwilling to provide that support.

U.S. Government Agency Securities- U.S. Government agency securities are issued or guaranteed by the U.S. Government or its agencies or instrumentalitiesor sponsored enterprises. Some obligations issued by U.S. Government agencies and instrumentalities, such as those of the Government National Mortgage Association ("GNMA"),are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal Home Loan Bank ("FHLB") or the Federal Farm Credit Bank ("FFCB"),by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the Federal National Mortgage Association (''Fannie Mae''), Federal Home Loan Mortgage Corporation (''Freddie Mac''), by thediscretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; and others, such as those of the Federal Farm Credit Bureau,only by the credit of the agency or instrumentality. U.S. Government securities bear fixed, floating or variable rates of interest. The market prices of U.S. government agency securities are not guaranteed by the U.S. Government. While the U.S. Government currently provides financial support to certain U.S. Government-sponsored agencies or instrumentalities, no assurance can be given that it will always do so, since it is not so obligated by law. U.S. Government securities include U.S. Treasury bills, notes and bonds, obligations of GNMA, FHLB, FFCB, Fannie Mae, Freddie Mac, the Federal Farm Credit Bureau, otherU.S. Government agency obligations and repurchase agreements secured thereby. U.S. Government agency securities are subject to credit risk,interest rate riskand market risk.

U.S. Treasury Obligations- U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics, and include bills (initial maturities of one year or less), notes (initial maturities between two and ten years), and bonds (initial maturities over ten years) issued by the U.S. Treasury.The prices of these securities (like all debt securities) change between issuance and maturity in response to fluctuating market interest rates and credit ratings. U.S. Treasury obligations are subject to credit risk and interest rate risk.The total amount of debt the Treasury is authorized to incur is subject to a statutory limit. Once the Treasury reaches the debt limit, Congress must raise, extend or otherwise modify the limit to enable the Treasury to incur additional debt to pay the obligations of the U.S. government, including principal and interest payments on certain U.S. Treasury obligations (such as Treasury bills, notes and bonds). Failure to, or potential failure to, increase the statutory debt limit could: increase the risk

Back to Table of Contents

that the U.S. government defaults on payments on certain U.S. Treasury obligations; cause the credit rating of the U.S. government to be downgraded or increase volatility in both stock and bond markets; result in higher debt servicing payments by the U.S. government; reduce prices of Treasury securities; and/or increase the costs of certain kinds of debt.

Variable or Floating Rate Obligations- Variable and floating rate securities provide for a periodic adjustment in the interest rate paid on the obligations. A variable rate obligation has an interest rate which is adjusted at predesignated periods in response to changes in the market rate of interest on which the interest rate is based. The adjustment intervals may be regular, and range from daily up to several months or may be event based, such as based on a change in the prime rate. Variable and floating rate obligations are less effective than fixed rate instruments at locking in a particular yield. Nevertheless, such obligations may fluctuate in value in response to interest rate changes if there is a delay between changes in market interest rates and the interest reset date for the obligation, or for other reasons.

The terms of the variable or floating rate demand instruments that the Fund may purchase provide that interest rates are adjustable at intervals ranging from daily up to several months, and the adjustments are based upon current market levels, the prime rate of a bank or other appropriate interest rate adjustment index as provided in the respective instruments. Some of these instruments are payable on demand on a daily basis or on not more than seven days' notice. Others, such as instruments with quarterly or semi-annual interest rate adjustments, may be put back to the issuer on designated days, usually on not more than thirty days' notice. Still others are automatically called by the issuer unless the Fund instructs otherwise. The Fund may consider the maturity of a long-term variable or floating rate demand instrument to be shorter than its ultimate stated maturity under specified conditions. The acquisition of variable or floating rate demand notes for the Fund must also meet the requirements of rules issued by the SEC applicable to the use of the amortized cost method of securities valuation, specifically Rule 2a-7 under the Investment Company Act. The Fund will also consider the liquidity of the market for variable and floating rate instruments, and in the event that such instruments are illiquid, the Fund's investments in such instruments will be subject to the limitation on illiquid investments.

Pursuant to Rule 2a-7 under the Investment Company Act, variable or floating rate obligations may be deemed to have maturities shorter than their stated maturities as follows:

(1) An obligation that is issued or guaranteed by the U.S. Government or any agency thereof which has a variable rate of interest readjusted no less frequently than every 397 days will be deemed by the Fund to have a maturity equal to the period remaining until the next readjustment of the interest rate. A U.S. Government security that is a floating rate security shall be deemed to have a remaining maturity of one day.

(2) A variable rate obligation, the principal amount of which must unconditionally be paid in 397 days or less, will be deemed by the Fund to have a maturity equal to the earlier of the period remaining until the next readjustment of the interest rate or the period remaining until the principal amount can be recovered through demand.

(3) A floating rate obligation, the principal amount of which must unconditionally be paid in 397 days or less, will be deemed by the Fund to have a maturity of one day, except for purposes of determining the Fund's weighted average life, in which case it shall be deemed to have a maturity equal to the period remaining until the principal amount can be recovered through demand.

(4) A variable rate obligation, the principal amount of which is scheduled to be paid in more than 397 days, that is subject to a demand feature will be deemed by the Fund to have a maturity equal to the longer of the period remaining until the next readjustment of the interest rate or the period remaining until the principal amount can be recovered through demand.

(5) A floating rate obligation, the principal amount of which is scheduled to be paid in more than 397 days, that is subject to a demand feature will be deemed by the Fund to have a maturity equal to the period remaining until the principal amount can be recovered through demand.

As used above, an obligation is "subject to a demand feature" when the Fund is entitled to receive the approximate amortized cost of the security plus accrued interest, if any, at the later of the time of exercise or the settlement of the transaction, paid within 397 calendar days of exercise.

When-Issued and Forward Commitment Transactions- These transactions involve a commitment by the Fund to purchase or sell securities with payment and delivery to take place at a future date, typically one to two months after the date of the transaction. The payment obligations and interest rate are fixed at the time the buyer enters into the transaction. These transactions enable the Fund to "lock-in" what the Manager believes to be an attractive price or yield on a particular security for a period of time, regardless of future changes in interest rates. For instance, in periods of rising interest rates and falling prices, the Fund might sell securities it owns on a forward commitment basis to limit its exposure to falling prices. In periods of falling interest rates and rising prices, the Fund might purchase a security on a when-issued or forward commitment basis and sell a similar security to settle such purchase, thereby obtaining the benefit of currently higher yields. Forward commitment transactions are executed for existing obligations, whereas in a when-issued transaction, the obligations have not yet been issued.

The value of securities purchased on a when-issued or forward commitment basis and any subsequent fluctuations in their value are reflected in the computation of the Fund's NAV starting on the date of the agreement to purchase the securities. Because the Fund has not yet paid for the securities, this produces an effect similar to leverage. The Fund does not earn interest on securities it has committed to purchase until the securities are paid for and delivered on the settlement date. When the Fund makes a forward commitment to sell securities it owns, the proceeds to be received upon settlement are included in its assets. Fluctuations in the market value of the underlying securities are not reflected in the Fund's NAV as long as the commitment to sell remains in effect.

When entering into a when-issued or forward commitment transaction, the Fund will rely on the other party to consummate the transaction; if the other party fails to do so, the Fund may be disadvantaged. If the other party fails to complete the trade, the Fund may lose the opportunity to obtain a favorable price. For purchases on a when-issued basis, the price of the security is fixed at the date of purchase, but delivery of and payment for the securities is not set until after the securities are issued. The value of when-issued securities is subject to market fluctuation during the interim period and no income accrues to the Fund until settlement takes place. Such transactions therefore involve a risk of loss if the value of the security to be purchased declines prior to the settlement date or if the value of the security to be sold increases prior to the settlement date. A sale of a when-issued

Back to Table of Contents

security also involves the risk that the other party will be unable to settle the transaction. When-issued, delayed-delivery and forward commitment transactions may cause the Fund to liquidate positions when it may not be advantageous to do so in order to satisfy its purchase or sale obligations.

Pursuant to Rule 18f-4 under the Investment Company Act, when-issued, delayed-delivery and forward commitment transactions will be deemed not to involve a senior security, provided that: the Fund intends to physically settle the transaction; and the transaction will settle within 35 days of its trade date. If such transactions are deemed senior securities, the Fund will maintain with its Custodiansegregated (or earmarked) liquid securities in an amount at least equal to the when-issued or forward commitment transaction. Earmarking or otherwise segregating a large percentage of the Fund's assets could impede the Manager's ability to manage the Fund's portfolio.

OTHER INVESTMENT STRATEGIES AND RISKS

In addition to the investment strategies and risks described in the Prospectus, the Fund may (except where indicated otherwise):

Engage in dollar rolls or purchase or sell securities on a when-issued or forward commitment basis. The purchase or sale of when-issued securities enables an investor to hedge against anticipated changes in interest rates and prices by locking in an attractive price or yield. The price of when-issued securities is fixed at the time the commitment to purchase or sell is made, but delivery and payment for the when-issued securities takes place at a later date, normally one to two months after the date of purchase. During the period between purchase and settlement, no payment is made by the purchaser to the issuer and no interest accrues to the purchaser. Such transactions therefore involve a risk of loss if the value of the security to be purchased declines prior to the settlement date or if the value of the security to be sold increases prior to the settlement date. A sale of a when-issued security also involves the risk that the other party will be unable to settle the transaction. Dollar rolls are a type of forward commitment transaction. Purchases and sales of securities on a forward commitment basis involve a commitment to purchase or sell securities with payment and delivery to take place at some future date, normally one to two months after the date of the transaction. As with when-issued securities, these transactions involve certain risks, but they also enable an investor to hedge against anticipated changes in interest rates and prices. Forward commitment transactions are executed for existing obligations, whereas in a when-issued transaction, the obligations have not yet been issued. When purchasing securities on a when-issued or forward commitment basis, a segregated amount of liquid assets at least equal to the value of purchase commitments for such securities will be maintained until the settlement date.

2	Invest in other investment companies (including affiliated investment companies) to the extent permitted by the Investment Company Act, or exemptive relief granted by the SEC.

Loan securities to broker-dealers or other institutional investors. Securities loans will not be made if, as a result, the aggregate amount of all outstanding securities loans by the Fund exceeds 33¹/₃% of its total assets (including the market value of collateral received). For purposes of complying with the Fund's investment policies and restrictions, collateral received in connection with securities loans is deemed an asset of the Fund to the extent required by law. The Manager receives compensation for administrative and oversight functions with respect to securities lending. The amount of such compensation depends on the income generated by the loan of the securities. The Fund continues to receive dividends or interest, as applicable, on the securities loaned and simultaneously earns either interest on the investment of the cash collateral or fee income if the loan is otherwise collateralized. The Fund does not currently engage in securities lending nor does the Manager anticipate that it will do so in the near future.

Enter into repurchase agreements. A repurchase agreement is an agreement under which securities are acquired by the Fund from a securities dealer or bank subject to resale at an agreed upon price on a later date. The acquiring Fund bears a risk of loss in the event that the other party to a repurchase agreement defaults on its obligations and the Fund is delayed or prevented from exercising its rights to dispose of the collateral securities. However, the Manager attempts to minimize this risk by entering into repurchase agreements only with financial institutions that are deemed to be of good financial standing.

Purchase securities sold in private placement offerings made in reliance on the "private placement" exemption from registration afforded by Section 4(a)(2) of the Securities Act, and resold to qualified institutional buyers under Rule 144A under the Securities Act ("Section 4(a)(2) securities"). The Fund will not invest more than 5% of its net assets in Section 4(a)(2) securities and illiquid securities unless the Manager determines that any Section 4(a)(2) securities held by such Fund in excess of this level are liquid.

INVESTMENT RESTRICTIONS

Fundamental Policies. The Fund has the following fundamental investment policy that enables it to invest in another investment company or series thereof that has substantially similar investment objectives and policies:

Notwithstanding any other limitation, the Fund may invest all of its investable assets in an open-end management investment company with substantially the same investment objectives, policies and limitations as the Fund. For this purpose, "all of the Fund's investable assets" means that the only investment securities that will be held by the Fund will be the Fund's interest in the investment company.

The Fund has no current intention to convert to a master-feeder structure, as permitted by the foregoing policy.

Fundamental Investment Restrictions.The following discusses the investment policies of the Fund. The following restrictions have been adopted by the Fund and may be changed with respect to the Fund only by the majority vote of the Fund's outstanding voting securities. "Majority of the outstanding voting securities" under the Investment Company Act and as used herein means, with respect to the Fund, the lesser of (a) 67% of the shares of the Fund present at the meeting if the holders of more than 50% of the shares are present and represented at the shareholders' meeting or (b) more than 50% of the shares of the Fund.

The Fund may not:

Purchase or sell real estate or real estate limited partnership interests, provided, however, that the Fund may invest in securities secured by real estate or interests therein or issued by companies which invest in real estate or interests therein when consistent with the other policies and limitations described in the Prospectus.

Back to Table of Contents

Invest in physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from purchasing or selling foreign currency, options, futures contracts, options on futures contracts, forward contracts, swaps, caps, floors, collars, securities on a forward-commitment or delayed-delivery basis, and other similar financial instruments).

3	Engage in the business of underwriting securities issued by others except to the extent that, in connection with the disposition of securities, the Fund may be deemed an underwriter under federal securities law.

Lend any security or make any other loan except (i) as otherwise permitted under the Investment Company Act, (ii) pursuant to a rule, order or interpretation issued by the SEC or its staff, (iii) through the purchase of a portion of an issue of debt securities in accordance with the Fund's investment objective, policies and limitations, or (iv) by engaging in repurchase agreements with respect to portfolio securities.

5	Issue any senior security except as otherwise permitted (i) under the Investment Company Act or (ii) pursuant to a rule, order or interpretation issued by the SEC or its staff.

Borrow money, except as otherwise permitted under the Investment Company Act or pursuant to a rule, order or interpretation issued by the SEC or its staff, including (i) as a temporary measure, (ii) by entering into reverse repurchase agreements, and (iii) by lending portfolio securities as collateral. For purposes of this investment limitation, the purchase or sale of options, futures contracts, options on futures contracts, forward contracts, swaps, caps, floors, collars and other similar financial instruments shall not constitute borrowing.

Invest more than 5% of its total assets (taken at market value) in securities of any one issuer, other than obligations issued by the U.S. Government, its agencies and instrumentalities, or purchase more than 10% of the voting securities of any one issuer, with respect to 75% of the Fund's total assets.

Invest more than 25% of its total assets in the securities of companies primarily engaged in any one industry provided that: (i) this limitation does not apply to obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities; and (ii) municipalities and their agencies and authorities are not deemed to be industries. For purposes of this restriction, the Fund will regard tax-exempt securities issued by municipalities and their agencies not to be an industry.

Non-Fundamental Investment Restrictions. The following non-fundamental investment restrictions apply to the Fund (except where noted otherwise) and may be changed with respect to the Fund by a vote of a majority of the Board. The Fund may not:

1	Invest more than 5% of its total assets in illiquid securities, including time deposits and repurchase agreements that mature in more than seven days; or

2	Purchase securities on margin or effect short sales, except that the Fund may obtain such short term credits as may be necessary for the clearance of purchases or sales of securities.

All percentage limitations on investments will apply at the time of the making of an investment and shall not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of such investment. Except for the investment restrictions listed above as fundamental or to the extent designated as such in the Prospectus with respect to the Fund, the other investment policies described in this SAI are not fundamental and may be changed by approval of the Trustees.

TEMPORARY OR DEFENSIVE INVESTMENTS

In times of unstable or adverse market, economic, political or other conditions, where the Manager believes it is appropriate and in the Fund's best interest, the Fund can invest up to 100% in cash and other types of securities for defensive or temporary purposes. It can also hold cash or purchase these types of securities for liquidity purposes to meet cash needs due to redemptions of Fund shares, or to hold while waiting to invest cash received from purchases of Fund shares or the sale of other portfolio securities. Uninvested assets do not earn income for the Fund, which may have a significant negative impact on the Fund's yield and may prevent the Fund from achieving its investment objective.

DISCLOSURE OF PORTFOLIO HOLDINGS

The Fund publishes on its website (www.americanbeaconfunds.com) a complete list of portfolio holdings as of the end of each business day, on the following business day. The Fund also publishes its portfolio holdings on a monthly basis as of the last business day of the month by the fifth business day of the following month. The daily and monthly holdings information will be available on the Fund's website for at least six months. In addition, the Fund files more detailed portfolio holdings information with the SEC on Form N-MFP, which will be publicly available on the SEC's website at www.sec.gov 60 days after the end of the month to which the information pertains.

Disclosure of Nonpublic Holdings.Occasionally, certain interested parties - including individual investors, institutional investors, intermediaries that distribute shares of the Fund, third-party service providers, rating and ranking organizations, and others - may request portfolio holdings information that has not yet been publicly disclosed by the Fund. The Manager has determined that selective disclosure of nonpublic portfolio holdings information for the Fund does not pose a significant risk of harm to Fund shareholders. Because of the nature of money market securities, interested parties could not utilize holdings information to trade in a manner harmful to the Fund and its shareholders. As noted above, a complete list of Fund portfolio holdings is posted to the Fund's website on a daily basis on the following business day. Selective disclosure of nonpublic holdings information as of the same business day is not restricted by the Fund. However, there may be certain situations in which disclosure of nonpublic holdings would not be in the best interests of Fund shareholders. Therefore, the Manager may, at its discretion, place restrictions on the disclosure of holdings under certain circumstances.

A variety of third party service providers require access to Fund holdings to provide services to the Fund or to assist the Manager in managing the Fund ("service providers"). The service providers have a duty to keep the Fund's nonpublic information confidential either through written contractual arrangements with the Fund (or another Fund service provider) or by the nature of their role with respect to the Fund (or the service provider). The

Back to Table of Contents

Fund has determined that disclosure of nonpublic holdings information to service providers fulfills a legitimate business purpose and is in the best interest of shareholders. In addition, the Fund has determined that disclosure of nonpublic holdings information to members of the Trust's Board of Trustees fulfills a legitimate business purpose, is in the best interest of Fund shareholders, and each Trustee is subject to a duty of confidentiality.

The Fund has ongoing arrangements to provide nonpublic holdings information to the following service providers, whose affiliates may also have access to such information:


Service Provider	Service	Holdings Access
Manager	Fund's investment management and administrator	Complete list on intraday basis with no lag
State Street Bank and Trust Co. ("State Street") and its designated foreign sub-custodians	Securities lending agent for Funds that participate in securities lending, Fund's custodian and foreign custody manager, sub-administrator, fund administration service provider, and foreign sub-custodian	Complete list on intraday basis with no lag
PricewaterhouseCoopers LLP	Fund's independent registered public accounting firm	Complete list on annual basis with no lag
KPMG International	Service provider to State Street	Complete list on annual basis with lag

Certain third parties are provided with nonpublic holdings information (either complete or partial lists) by the Manager or another service provider on an ad hoc basis. These third parties include: broker-dealers, pricing services, legal counsel, and issuers (or their agents). Broker-dealers utilized by the Fund in the process of purchasing and selling portfolio securities or providing market quotations receive limited holdings information on a current basis with no lag. The Fund utilizes various pricing services to supply market quotations and evaluated prices to State Street. State Street and the Manager may disclose current nonpublic holdings to those pricing services. An investment manager may provide holdings information to legal counsel when seeking advice regarding those holdings. From time to time, an issuer (or its agent) may contact the Fund requesting confirmation of ownership of the issuer's securities. Such holdings information is provided to the issuer (or its agent) as of the date requested. The Fund does not have written contractual arrangements with these third parties regarding the confidentiality of the holdings information. However, the Fund would not continue to utilize a third party that the Manager determined to have misused nonpublic holdings information.

The Fund has ongoing arrangements to provide periodic holdings information to certain organizations that publish ratings and/or rankings for the Fund or that redistribute the Fund's holdings to financial intermediaries to facilitate their analysis of the Fund. The Fund has determined that disclosure of holdings information to such organizations fulfills a legitimate business purpose and is in the best interest of shareholders, as it provides existing and potential shareholders with an independent basis for evaluating the Fund in comparison to other mutual funds. As of the date of this SAI, all such organizations receive holdings information after it has been made public on the Fund's website.

No compensation or other consideration may be paid to the Fund, the Fund's service providers, or any other party in connection with the disclosure of portfolio holdings information.

TRUSTEES AND OFFICERS OF THE TRUST

The Board of Trustees

The Trust is governed by its Board of Trustees. The Board is responsible for and oversees the overall management and operations of the Trust and the Fund, which includes the general oversight and review of the Fund's investment activities, in accordance with federal law and the law of the Commonwealth of Massachusetts as well as the stated policies of the Fund. The Board oversees the Trust's officers and service providers, including American Beacon, which is responsible for the management of the day-to-day operations of the Fund based on policies and agreements reviewed and approved by the Board. In carrying out these responsibilities, the Board regularly interacts with and receives reports from senior personnel of service providers, including American Beacon's investment personnel and the Trust's CCO. The Board also is assisted by the Trust's independent registered public accounting firm (which reports directly to the Trust's Audit and Compliance Committee), independent counsel and other experts as appropriate, all of whom are selected by the Board.

Risk Oversight

Consistent with its responsibility for oversight of the Trust and the Fund, the Board oversees the management of risks relating to the administration and operation of the Trust and the Fund. American Beacon, as part of its responsibilities for the day-to-day operations of the Fund, is responsible for day-to-day risk management for the Fund. The Board, in the exercise of its reasonable business judgment, also separately considers potential risks that may impact the Fund. The Board performs this risk management oversight directly and, as to certain matters, through its committees (described below) and through the Board members who are not "interested persons" of the Trust as defined in Section 2(a)(19) of the Investment Company Act ("Independent Trustees"). The following provides an overview of the principal, but not all, aspects of the Board's oversight of risk management for the Trust and the Fund.

In general, the Fund's risks include, among others, investment risk, credit risk, liquidity risk, securities selection risk and valuation risk. The Board has adopted, and periodically reviews, policies and procedures designed to address these and other risks to the Trust and the Fund. In addition, under the general oversight of the Board, American Beacon, the Fund's investment adviser, and other service providers to the Fund have themselves adopted a variety of policies, procedures and controls designed to address particular risks to the Fund. Different processes, procedures and controls are employed with respect to different types of risks. Further, American Beacon as manager of the Fund oversees and regularly monitors the investments, operations and compliance of the Fund's investment advisers.

Back to Table of Contents

The Board also oversees risk management for the Trust and the Fund through review of regular reports, presentations and other information from officers of the Trust and other persons. Senior officers of the Trust, and senior officers of American Beacon, and the Fund's CCO regularly report to the Board on a range of matters, including those relating to risk management. The Board and the Investment Committee also regularly receive reports from American Beacon with respect to the investments, securities trading and securities lending activities of the Fund, as applicable. In addition to regular reports from American Beacon, the Board also receives reports regarding other service providers to the Trust, either directly or through American Beacon or the Fund's CCO, on a periodic or regular basis. At least annually, the Board receives a report from the Fund's CCO regarding the effectiveness of the Fund's compliance program. Also, typically on an annual basis, the Board receives reports, presentations and other information from American Beacon in connection with the Board's consideration of the renewal of each of the Trust's agreements with American Beacon and the Trust's distribution planunder Rule 12b-1 under the Investment Company Act.

Senior officers of the Trust and American Beacon also report regularly to the Audit and Compliance Committee on Fund valuation matters and on the Trust's internal controls and accounting and financial reporting policies and practices. In addition, the Audit and Compliance Committee receives regular reports from the Trust's independent registered public accounting firm on internal control and financial reporting matters. On at least a quarterly basis, the Audit and Compliance Committee meets with the Fund's CCO to discuss matters relating to the Fund's compliance program.

Board Structure and Related Matters

Independent Trustees constitute at least three-quarters of the Board. Brenda A. Cline, an Independent Trustee, serves as Independent Chair of the Board. The Independent Chair's responsibilities include: setting an agenda for each meeting of the Board; presiding at all meetings of the Board and Independent Trustees; and serving as a liaison with other Trustees, the Trust's officers and other management personnel, and counsel to the Fund. The Independent Chair shall perform such other duties as the Board may from time to time determine.

The Trustees discharge their responsibilities collectively as a Board, as well as through Board committees, each of which operates pursuant to a charter approved by the Board that delineates the responsibilities of that committee. The Board has established three standing committees: the Audit and Compliance Committee, the Investment Committee and the Nominating and Governance Committee. For example, the Investment Committee is responsible for oversight of the process, typically performed annually, by which the Board considers and approves the Fund's investment advisory agreement with American Beacon, while specific matters related to oversight of the Fund's independent auditors have been delegated by the Board to its Audit and Compliance Committee, subject to approval of the Audit and Compliance Committee's recommendations by the Board. The members and responsibilities of each Board committee are summarized below.

The Board periodically evaluates its structure and composition as well as various aspects of its operations. The Board believes that its leadership structure, including its Independent Chair position and its committees, is appropriate for the Trust in light of, among other factors, the asset size and nature of the funds in the Trust, the number of series of the American Beacon Funds Complex overseen by the Board, the arrangements for the conduct of the Fund's operations, the number of Trustees, and the Board's responsibilities. On an annual basis, the Board conducts a self-evaluation that considers, among other matters, whether the Board and its committees are functioning effectively and whether, given the size and composition of the Board and each of its committees, the Trustees are able to oversee effectively the number of Funds in the complex.

The Trust is part of the American Beacon Funds Complex, which is comprised of 24series within the American Beacon Funds, 1 series within the American Beacon Institutional Funds Trust, and 3series within the American Beacon Select Funds. The same persons who constitute the Board of the Trust also constitute the Board of the American Beacon Institutional Funds Trust and the American Beacon Funds, and each Trustee oversees the Trusts' combined 28series.

The Board holds five (5) regularly scheduled meetings each year. The Board may hold special meetings, as needed, either in person or by telephone, to address matters arising between regular meetings. The Independent Trustees also hold at least one in-person meeting each year during a portion of which management is not present and may hold special meetings, as needed, either in person or by telephone.

The Trustees of the Trust are identified in the tables below, which provide information as to their principal business occupations and directorships held during the last five years and certain other information. Subject to the Trustee Retirement Plan described below, a Trustee serves until his or her successor is elected and qualified or until his or her earlier death, resignation or removal. The address of each Trustee listed below is 220 East Las Colinas Boulevard, Suite 1200, Irving, Texas 75039. Each Trustee serves for an indefinite term or until his or her removal, resignation, or retirement.*

For her service as Board Chair, Ms. Cline receives an additional annual retainer of $50,000. Although she attends several committee meetings at each quarterly Board meeting, she receives a single $2,500 fee each quarter for her attendance at the Audit Committee and Investment Committee meetings. The chairpersons of the Audit Committee and the Investment Committee each receive an additional annual retainer of $25,000 and the Chair of the Nominating and Governance Committee receives an additional annual retainer of $10,000.


The following table shows total compensation (excluding reimbursements) paid by the Trusts to each Trustee for the fiscal year ended December 31, 2023.

1	Upon her retirement from the Board, Ms. Cline is eligible for flight benefits afforded to Eligible Trustees who served on the Boards prior to September 12, 2008 as described below.

The Boards have adopted a Trustee Retirement Plan. The Trustee Retirement Plan provides that a Trustee who has served on the Boards prior to September 12, 2008, and who has reached a mandatory retirement age established by the Board (currently 75) is eligible to elect Trustee Emeritus status ("Eligible Trustees"). Eligible Trustees who have served on the Board of one or more Trusts for at least five years may elect to retire from the Board at an earlier age and immediately assume Trustee Emeritus status. The Board has determined that, other than the Trustee Retirement Plan established for Eligible Trustees, no other retirement benefits will accrue for current or future Trustees. Ms. Cline is the only Eligible Trustee.

Each Eligible Trustee and his or her spouse (or designated companion) may receive annual flight benefits from the Trusts of up to $40,000 combined, on a tax-grossed up basis, on American Airlines (a subsidiary of the Manager's former parent company) for a maximum period of 10 years, depending upon length of service prior to September 12, 2008. Eligible Trustees may opt to receive instead an annual retainer of $20,000 from the Trusts in lieu of flight benefits. No retirement benefits are accrued for Board service after September 12, 2008.

A Trustee Emeritus must be reasonably available to provide advice, counseling and assistance to the Trustees and American Beacon as needed, as agreed to from time to time by the parties involved; however, a Trustee Emeritus does not have any voting rights at Board meetings and is not subject to election by shareholders of the Fund. Currently, three individuals who retired from the Board and accrued retirement benefits for periods prior to September 12, 2008, have assumed Trustee Emeritus status. Two individuals and their spouses receive annual flight benefits of up to $40,000 combined, on a tax-grossed up basis, on American Airlines. The other individual receives an annual retainer of $20,000 from the Trusts in lieu of flight benefits.

The Manager, the Trust and the Distributor have adopted a Code of Ethics under Rule 17j-1 of the Investment Company Act. The Code of Ethics significantly restricts the personal trading of all employees with access to non-public portfolio information. For example, the Code of Ethics generally requires pre-clearance of all personal securities trades (with limited exceptions) and prohibits employees from purchasing or selling a security that is being purchased or sold or being considered for purchase (with limited exceptions) or sale by any Fund. In addition, the Manager's and the Trust's Code of Ethics requires employees to report trades in shares of the Trusts. The Code of Ethics is on public file with, and may be obtained from, the SEC.

OTHER SERVICE PROVIDERS

State Street, located at One CongressStreet, Suite 1, Boston, Massachusetts 02114-2016, serves as custodian for the Fund. The Manager also has entered into a sub-administration agreement with State Street. Under the sub-administration agreement, State Street provides the Fund with certain financial reporting and tax services.

SS&C GIDS, Inc., located at 2000 Crown Colony Drive, Quincy, Massachusetts 02169, is the transfer agent and dividend paying agent for the Trust and provides these services to Fund shareholders.

The Fund's independent registered public accounting firm is PricewaterhouseCoopers LLP, which is located at 101 Seaport Blvd., Suite 500, Boston, MA 02210.

K&L Gates LLP, 1601 K Street, NW, Washington, D.C. 20006, serves as legal counsel to the Fund.

PORTFOLIO SECURITIES TRANSACTIONS

In selecting brokers or dealers to execute particular transactions, the Manager is authorized to consider "brokerage and research services" (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934, as amended), provision of statistical quotations (including the quotations necessary to determine the Fund's NAV), and other information provided to the Fund, or the Manager, provided, however, that the Manager must always seek best execution. Research and brokerage services may include information on portfolio companies, economic analyses, and other investment research services. The Trust does not allow the Manager to enter arrangements to direct transactions to broker-dealers as compensation for the promotion or sale of Trust shares by those broker-dealers.

REDEMPTIONS IN KIND

Although the Fund intends to redeem shares in cash, the Fund reserves the right to pay the redemption price in whole or in part by a distribution of securities or other assets. However, shareholders always will be entitled to redeem shares for cash up to the lesser of $250,000 or 1% of the Fund's net asset value during any 90-day period. Redemption in kind is not as liquid as a cash redemption. In addition, to the extent the Fund redeems its shares in this manner, the shareholder assumes the risk of a subsequent change in the market value of those securities, the cost of liquidating the securities and the possibility of a lack of a liquid market for those securities.

NET ASSET VALUE

It is the policy of the Fund to attempt to maintain a constant price per share of $1.00. There can be no assurance that a $1.00 net asset value per share will be maintained. The portfolio instruments held by the Fund are valued based on the amortized cost valuation technique pursuant to Rule 2a-7 under the Investment Company Act. This involves valuing an instrument at its cost and thereafter assuming a constant amortization to maturity of any discount or premium, even though the portfolio security may increase or decrease in market value. Such market fluctuations are generally in response to changes in interest rates. Use of the amortized cost valuation method requires the Fund to purchase instruments having remaining maturities of 397 days or less, to maintain a dollar-weighted average portfolio maturity and dollar-weighted average life maturity of 60 and 120 days or less, respectively, to invest only in securities determined by the Manager pursuant to procedures adopted by the Board to present minimal credit risks and comply with the liquidity and diversification requirements pursuant to Rule 2a-7 under the Investment Company Act.

TAX INFORMATION

The tax information in the Prospectus and in this section relates solely to the federal income tax law and assumes that the Fund will continue to qualify each taxable year as a "regulated investment company" ("RIC") under the Internal Revenue Code (as discussed below). The tax information in this section is only a summary of certain key federal tax considerations affecting the Fund and its shareholders and is in addition to the tax information provided in the Prospectus. No attempt has been made to present a complete explanation of the federal income tax treatment of the Fund or the tax implications to its shareholders. The discussions here and in the Prospectus are not intended as substitutes for careful tax planning. The tax information is based on the Internal Revenue Code and applicable regulations in effect, and administrative pronouncements and judicial decisions publicly available, on the date of this SAI. Future legislative, regulatory or administrative changes or court decisions may significantly change the tax rules applicable to the Fund and its shareholders. Any of these changes or court decisions may have a retroactive effect.

Taxation of the Fund

Back to Table of Contents

The Fund intends to continue to qualify each taxable year for treatment as a RIC under Subchapter M of Chapter 1 of Subtitle A of the Internal Revenue Code. To so qualify, the Fund (which is treated as a separate corporation for these purposes) must, among other requirements:

■

Derive at least 90% of its gross income each taxable year from (1) dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of securities or foreign currencies, or other income, including gains from options, futures or forward contracts, derived with respect to its business of investing in securities or those currencies ("Qualifying Income") and (2) net income derived from an interest in a "qualified publicly traded partnership" ("QPTP") ("Gross Income Requirement"). A QPTP is a "publicly traded partnership" that meets certain qualifying income requirements other than a partnership at least 90% of the gross income of which is Qualifying Income;

■

Diversify its investments so that, at the close of each quarter of its taxable year, (1) at least 50% of the value of its total assets is represented by cash and cash items, Government securities, securities of other RICs and other securities, with those other securities limited, in respect of any one issuer, to an amount that does not exceed 5% of the value of the Fund's total assets and that does not represent more than 10% of the issuer's outstanding voting securities, and (2) not more than 25% of the value of its total assets is invested in (a) the securities (other than Government securities or securities of other RICs) of any one issuer, (b) the securities (other than securities of other RICs) of two or more issuers the Fund controls (by owning 20% or more of their voting power) that are determined to be engaged in the same, similar or related trades or businesses ("Diversification Requirements"), or (c) the securities of one or more QPTPs; and

■

Distribute annually to its shareholders at least the sum of 90% of its investment company taxable income (generally, net investment income, the excess (if any) of net short-term capital gain over net long-term capital loss, and net gains and losses (if any) from certain foreign currency transactions, all determined without regard to any deduction for dividends paid) and 90% of its net exempt interest income ("Distribution Requirement").

The Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the extent it fails to distribute by the end of any calendar year substantially all of its ordinary income for that year and substantially all of its capital gain net income for the one-year period ending on October 31 of that year, plus certain other amounts. The Fund intends to make sufficient distributions by the end of each calendar year to avoid liability for the Excise Tax.

By qualifying for treatment as a RIC, the Fund (but not its shareholders) will be relieved of federal income tax on the part of its investment company taxable income and net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) that it distributes to its shareholders. If for any taxable year the Fund does not qualify for that treatment- either (1) by failing to satisfy the Distribution Requirement, even if it satisfies the Gross Income and Diversification Requirements ("Other Requirements"), or (2) by failing to satisfy any of the Other Requirements and is unable to, or determines not to, avail itself of Internal Revenue Code provisions that enable a RIC to cure a failure to satisfy any of the Other Requirements as long as the failure "is due to reasonable cause and not due to willful neglect" and the RIC pays a deductible tax calculated in accordance with those provisions and meets certain other requirements - then for federal tax purposes, all of its taxable income (including its net capital gain) would be subject to tax at the regular corporate rate without any deduction for dividends paid to its shareholders, and the dividends it pays would be taxable to its shareholders as ordinary income (or possibly, (a) for individual and certain other non-corporate shareholders (each, an "individual") as "qualified dividend income" and/or (b) in the case of corporate shareholders that meet certain holding period and other requirements regarding their Fund shares, as eligible for the dividends-received deduction ("DRD") ) to the extent of the Fund's current and accumulated earnings and profits. Failure to qualify for RIC treatment would therefore have a negative impact on the Fund's income and performance. Furthermore, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before re-qualifying for RIC treatment. It is possible that the Fund will not qualify as a RIC in any given taxable year.

The Fund may acquire securities issued with original issue discount ("OID") (such as STRIPS). As a holder of those securities, the Fund must include in its gross income the OID that accrues on them during the taxable year, even if it receives no corresponding payment on them during the year. Because the Fund annually must distribute substantially all of its investment company taxable income, including any accrued OID, to satisfy the Distribution Requirement and avoid imposition of the Excise Tax, it may be required in a particular taxable year to distribute as a dividend an amount that is greater than the total amount of cash it actually receives. Those distributions will be made from the Fund's cash assets or from the proceeds of sales of its portfolio securities, if necessary. The Fund may realize capital gains or losses from those sales, which would increase or decrease its investment company taxable income (net short-term).

Taxation of the Fund's Shareholders

General - Dividends and other distributions the Fund declares in the last quarter of any calendar year that are payable to shareholders of record on a date in that quarter will be deemed to have been paid by the Fund and received by those shareholders on December 31of that year if the Fund pays the distributions during the following January. Accordingly, those distributions will be reportable by, and taxed to, those shareholders for the taxable year in which that December 31 falls.

If Fund shares are redeemed at a loss after being held for six months or less, the loss will be treated as long-term, instead of short-term, capital loss to the extent of any capital gain distributions received on those shares. In addition, any loss a shareholder realizes on a redemption of Fund shares will be disallowed to the extent the shares are replaced within a 61-day period beginning 30 days before and ending 30 days after the redemption; in that case, the basis in the acquired shares will be adjusted to reflect the disallowed loss. Investors also should be aware that the price of Fund shares at any time may reflect the amount of a forthcoming dividend or other distribution so if they purchase Fund shares shortly before the record date for a distribution, they maypay full price for the shares and receive some part of the price back as a taxable distribution, even though it represents a partial return of invested capital.

Backup Withholding
The Fund is required to withhold and remit to the U.S. Treasury 24% of dividends, capital gain distributions, and redemption proceeds (regardless of the extent to which gain or loss may be realized) otherwise payable to any individual who fails to certify that the taxpayer identification number furnished to the Fund is correct or who furnishes an incorrect number (together with the withholding described in the next sentence, "backup withholding"). Withholding at that rate also is required from the Fund's dividends and capital gain distributions otherwise payable to such a shareholder who (1) is subject to backup withholding for failure to report the receipt of interest or dividend income properly or (2) fails to certify to the

Fund that he or she is not subject to backup withholding or that it is a corporation or other "exempt recipient." Backup withholding is not an additional tax; rather, any amounts so withheld may be credited against the shareholder's federal income tax liability or refunded if proper documentation is submitted to the IRS.

Non-U.S. Shareholders- Dividends the Fund pays to a shareholder who is a nonresident alien individual or foreign entity (each a "non-U.S. shareholder") - other than (1) dividends paid to a non-U.S. shareholder whose ownership of the Fund's shares is effectively connected with a trade or business within the United States the shareholder conducts and (2) capital gain distributions paid to a nonresident alien individual who is physically present in the United States for no more than 182 days during the taxable year - generally are subject to 30% federal withholding tax (unless a reduced rate of withholding or a withholding exemption is provided under an applicable treaty). However, two categories of dividends the Fund might pay, "short-term capital gain dividends" and "interest-related dividends," to non-U.S. shareholders (with certain exceptions) and reported by it in writing to its shareholders are exempt from that tax. "Short-term capital gain dividends" are dividends that are attributable to net short-term gain, computed with certain adjustments. "Interest-related dividends" are dividends that are attributable to "qualified net interest income" (i.e., "qualified interest income," which generally consists of certain OID, interest on obligations "in registered form," and interest on deposits, less allocable deductions) from sources within the United States. Non-U.S. shareholders are urged to consult their own tax advisers concerning that applicability of that withholding tax.

Foreign Account Tax Compliance Act ("FATCA")- Under FATCA, "foreign financial institutions" ("FFIs") and "non-financial foreign entities" ("NFFEs") that are Fund shareholders may be subject to a generally nonrefundable 30% withholding tax on dividends the Fund pays. As discussed more fully below, the FATCA withholding tax generally can be avoided (a) by an FFI, if it reports certain information regarding direct and indirect ownership of financial accounts U.S. persons hold with the FFI, and (b) by an NFFE that certifies its status as such and, in certain circumstances, information regarding substantial U.S. owners. Proposed regulations (having current effect) have been issued to eliminate certain FATCA withholding taxes, including the withholding tax on investment sale proceeds that was scheduled to begin in 2019, and to defer the effective date of other taxes.

The U.S. Treasury has negotiated intergovernmental agreements ("IGAs") with certain countries and is in various stages of negotiations with other foreign countries with respect to alternative approaches to implement FATCA. An entity in one of those countries may be required to comply with the terms of the IGA instead of U.S. Treasury regulations. An FFI resident in a country that has entered into a Model I IGA with the United States must report to that country's government (pursuant to the terms of the applicable IGA and applicable law), which will, in turn, report to the IRS. An FFI resident in a Model II IGA country generally must comply with U.S. regulatory requirements, with certain exceptions, including the treatment of recalcitrant accountholders. An FFI resident in one of those countries that complies with whichever of the foregoing applies will be exempt from FATCA withholding.

An FFI can avoid FATCA withholding by becoming a "participating FFI," which requires the FFI to enter into a tax compliance agreement with the IRS under the Internal Revenue Code. Under such an agreement, a participating FFI agrees to (1) verify and document whether it has U.S. accountholders, (2) report certain information regarding their accounts to the IRS, and (3) meet certain other specified requirements.

An NFFE that is the beneficial owner of a payment from the Fund can avoid FATCA withholding generally by certifying its status as such and, in certain circumstances, either that (1) it does not have any substantial U.S. owners or (2) it does have one or more such owners and reports the name, address, and taxpayer identification number of each such owner. The NFFE will report to the Fund or other applicable withholding agent, which may, in turn, report information to the IRS.

Those foreign shareholders also may fall into certain exempt, excepted, or deemed compliant categories established by U.S. Treasury regulations, IGAs, and other guidance regarding FATCA. An FFI or NFFE that invests in the Fund will need to provide it with documentation properly certifying the entity's status under FATCA to avoid FATCA withholding. The requirements imposed by FATCA are different from, and in addition to, the tax certification rules to avoid backup withholding described above. Foreign investors are urged to consult their tax advisers regarding the application of these requirements to their own situation and the impact thereof on their investment in the Fund.

Other Taxes
Statutory rules and regulations regarding state and local taxation of dividends may differ from the federal income taxation rules described above. Distributions may also be subject to additional state, local and foreign taxes depending on each shareholder's situation.

DESCRIPTION OF THE TRUST

The Trust is an entity of the type commonly known as a "Massachusetts business trust." Under Massachusetts law, shareholders of such a trust may, under certain circumstances, be held personally liable for its obligations. However, the Trust's Declaration of Trust contains an express disclaimer of shareholder liability for acts or obligations of the Trust and provides for indemnification and reimbursement of expenses out of Trust property for any shareholder held personally liable for the obligations of the Trust. The Declaration of Trust also provides that the Trust may maintain appropriate insurance (e.g., fidelity bonding) for the protection of the Trust, its shareholders, Trustees, officers, employees and agents to cover possible tort and other liabilities. Thus, the risk of a shareholder incurring financial loss due to shareholder liability is limited to circumstances in which both inadequate insurance existed and the Trust itself was unable to meet its obligations. The Trust has not engaged in any other business.

The following individuals (and members of that individual's "immediate family") are eligible to purchase shares of the Fund with an initial investment below the minimum of $1 million: (i) employees of the Manager, or its parent company Resolute Investment Managers, Inc., (ii) members of the Trust's Board of Trustees, (iii) employees of Kelso/Estancia, and (iv) members of the Manager's Board of Directors. The term "immediate family" refers to one's spouse, children, grandchildren, grandparents, parents, parents-in-law, brothers and sisters, sons and daughters in-law, a sibling's spouse, a spouse's sibling, aunts, uncles, nieces and nephews; relatives by virtue of remarriage (step-children, step-parents, etc.).

APPENDIX A

Ratings Definitions

Below are summaries of the ratings definitions used by some of the rating organizations. Those ratings represent the opinion of the rating organizations as to the credit quality of the issues that they rate. The summaries are based upon publicly available information provided by the rating organizations.

Ratings of Long-Term Obligations and Preferred Stocks- The Fund utilizes ratings provided by rating organizations in order to determine eligibility of long-term obligations. The ratings described in this section may also be used for evaluating the credit quality for preferred stocks.

Credit ratings typically evaluate the safety of principal and interest payments, not the market value risk of bonds. The rating organizations may fail to update a credit rating on a timely basis to reflect changes in economic or financial conditions that may affect the market value of the security. For these reasons, credit ratings may not be an accurate indicator of the market value of a bond.

The four highest Moody's ratings for long-term obligations (or issuers thereof) are Aaa, Aa, A and Baa. Obligations rated Aaa are judged to be of the highest quality,subject to the lowest level of credit risk. Obligations rated Aa are judged to be of high quality and are subject to very low credit risk. Obligations rated A are judged to be upper-medium grade and are subject to low credit risk. Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and, as such, may possess certain speculative characteristics.

Moody's ratings of Ba, B, Caa, Ca and C are considered below investment grade. Obligations rated Ba are judged to bespeculative and are subject to substantial credit risk. Obligations rated B are considered speculative and are subject to high credit risk. Obligations rated Caa are judged to be speculative, of poor standing and subject to very high credit risk. Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest. Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest. Moody's appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a "(hyb)" indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies, and securities firms. By their terms, hybrid securities allow for the omission of scheduled dividends, interest, or principal payments, which can potentially result in impairment if such an omission occurs. Hybrid securities may also be subject to contractually allowable write-downs of principal that could result in impairment. Together with the hybrid indicator, the long-term obligation rating assigned to a hybrid security is an expression of the relative credit risk associated with that security.

The four highest S&P Global ratings for long-term obligations are AAA, AA, A and BBB. An obligation rated AAA has the highest rating assigned by S&P Global and indicates that the obligor's capacity to meet its financial commitments on the obligation is extremely strong. An obligation rated AA differs from the highest-rated obligations only to a small degree. The obligor's capacity to meet its financial commitments on the obligation is very strong. An obligation rated A is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor's capacity to meet its financial commitments on the obligation is still strong. An obligation rated BBB exhibits adequate protection parameters; however, adverse economic conditions or changing circumstances are more likely to weaken the obligor's capacity to meet its financial commitments on the obligation.

S&P Global ratings of BB, B, CCC, CC, and Care regarded as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposure to adverse conditions. An obligation rated BB is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions thatcould lead to the obligor's inadequate capacity to meet its financial commitments on the obligation. An obligation rated B is more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitments on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitments on the obligation. An obligation rated CCC is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitments on the obligation. An obligation rated CC is currently highly vulnerable to nonpayment. The CC rating is used when a default has not yet occurred but S&P Global expects default to be a virtual certainty, regardless of the anticipated time to default. An obligation rated C is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared with obligations that are rated higher. An obligation rated D is in default or in breach of an imputed promise. For non-hybrid capital instruments, the D rating category is used when payments on an obligation are not made on the date due, unless S&P Global believes that such payments will be made within the next five business days in the absence of a stated grace period or within the earlier of the stated grace period or the next 30 calendar days. The D rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligationis lowered to D if it is subject to a distressed debt restructuring. An SD (selective default) rating is assigned when S&P Global believes that the obligor has selectively defaulted on a specific issue or class of obligations but it will continue to meet its payment obligations on other issues or classes of obligations in a timely manner. The ratings from AA to CCC may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the rating categories.

The four highest ratings for long-term obligations by Fitch Ratings are AAA, AA, A and BBB. Obligations rated AAA are deemed to be of the highest credit quality. AAA ratings denote the lowest expectation of credit risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events. Obligations rated AA are deemed to be of very high credit quality. AA ratings denote expectations of very low credit risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events. Obligations rated A are deemed to be of high credit quality. An A rating denotes expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business oreconomic conditions than is the case for higher ratings. Obligations rated BBB are deemed to be of good credit

A-1

Back to Table of Contents

quality. BBB ratings indicate that expectations of creditrisk are currently low. The capacity for payment of financial commitments is considered adequate,but adverse business or economic conditions are more likely to impair this capacity. This is the lowest investment grade category.

Fitch's ratings of BB, B, CCC, CC, C, RD and D are considered below investment grade or speculative grade. Obligations rated BB are deemed to be speculative. BB ratings indicate an elevated vulnerability to credit risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial alternatives may be available to allow financial commitments to be met. Obligations rated B are deemed to be highly speculative. B ratings indicate that material credit risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, the capacity for continued payment is vulnerable to deterioration in the business and economic environment. CCC ratings indicate that substantial credit risk is present. CC ratings indicate very high levels of credit risk. C indicates exceptionally high levels of credit risk Obligations rated C indicate a default or default-like process had begun, or the issuer is in standstill, or for a closed funding vehicle, payment capacity is irrevocably impaired. Ratings in the categories of 'CCC', 'CC', and 'C' can also relate to obligations or issuers that are in default. In this case, the rating does not opine on default risk but reflects the recovery expectation only. Conditions that are indicative of a C category rating for an issuer include: (a) the issuer has entered into a grace or cure period following non-payment of a material financial obligation; (b) the issuer has entered into a temporary negotiated waiver or standstill agreement following a payment default on a material financial obligation; (c) the formal announcement by the issuer or their agent of a distressed debt exchange; or (d) a closed financing vehicle where payment capacity is irrevocably impaired such that it is not expected to pay interest and/or principal in full during the life of the transaction, but where no payment default is imminent. Obligations rated RD indicate an issuer that, in Fitch Ratings' opinion, has experienced an uncured payment default or distressed debt exchange on a bond, loan or other material financial obligation but which has not entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure, and which has not otherwise ceased operating. This would include: (a) the selective payment default on a specific class or currency of debt; (b) the uncured expiry of any applicable grace period, cure period or default forbearance period following a payment default on a bank loan, capital markets security or other material financial obligation; (c) the extension of multiple waivers or forbearance periods upon a payment default on one or more material financial obligations, either in series or in parallel; or (d) ordinary execution of a distressed debt exchange on one or more material financial obligations. Obligations rated D indicate an issuer that, in Fitch Ratings' opinion, has entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure or that has otherwise ceased business. Default ratings are not assigned prospectively to entities or their obligations; within this context, non-payment on an instrument that contains a deferral feature or grace period will generally not be considered a default until after the expiration of the deferral or grace period, unless a default is otherwise driven by bankruptcy or other similar circumstance, or by a distressed debt exchange. In all cases, the assignment of a default rating reflects the agency's opinion as to the most appropriate rating category consistent with the rest of its universe of ratings and may differ from the definition of default under the terms of an issuer's financial obligations or local commercial practice. The modifiers "+" or "-" may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the AAA obligation rating category, or to corporate finance obligation ratings in the categories below CCC.

Ratings of Municipal Obligations- Moody's ratings for short-term investment-grade municipal obligations are designated Municipal Investment Grade (MIG or VMIG in the case of variable rate demand obligations) and are divided into three levels - MIG/VMIG 1, MIG/VMIG 2, and MIG/VMIG 3. The MIG/VMIG 1 designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing. The MIG/VMIG 2 designation denotes strong credit quality. Marginsof protection are ample, although not as large as in the preceding group. The MIG/VMIG 3 designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established. An SG designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

S&P Global uses SP-1, SP-2, SP-3, and D to rate short-term municipal obligations. A rating of SP-1 denotes a strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation. A rating of SP-2 denotes a satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes. A rating of SP-3 denotes a speculative capacity to pay principal and interest. A rating of D is assigned upon failure to pay the note when due, completion of a distressed debt restructuring, or the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions.

Ratings of Short-Term Obligations- Moody's short-term ratings, designated as P-1, P-2, P-3, or NP, are opinions of the ability of issuers to honor short-term financial obligations that generally have an original maturity not exceeding thirteen months. The rating P-1 (Prime-1) is the highest short-term rating assigned by Moody's and it denotes an issuer (or supporting institution) that has a superior ability to repay short-term debt obligations. The rating P-2 (Prime-2) denotes an issuer (or supporting institution) that has a strong ability to repay short-term debt obligations. The rating P-3 (Prime-3) denotes an issuer (or supporting institution) that has an acceptable ability to repayshort-term obligations. The rating NP (Not Prime) denotes an issuer (or supporting institution) that does not fall within any of the Prime rating categories.

S&P Global short-term ratings are generally assigned to those obligations considered short-term in the relevant market. In the U.S., for example, that typically means obligations with an original maturity of no more than 365 days. A short-term obligation rated A-1 is rated in the highest category by S&P Global and indicates that the obligor's capacity to meet its financial commitments on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitments on these obligations is extremely strong. A short-term obligation rated A-2 is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitments on the obligation is satisfactory. A short-term obligation rated A-3 exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor's capacity to meet its financial commitments on the obligation. A short-term obligation rated B is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties thatcould lead to the obligor's inadequate capacity to meet its financial commitments. A short-term obligation rated C is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation. A short-term obligation rated D is in default or in breach of an imputed promise. For non-hybrid capital instruments, the D rating category is used when payments on an obligation are not made on the date due, unless S&P Global believes that such

A-2

Back to Table of Contents

payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation's rating is lowered to D if it is subject to a distressed debt restructuring. An SD rating is assigned when S&P Global believes that the obligor has selectively defaulted on a specific issue or class of obligations but it will continue to meet its payment obligations on other issues or classes of obligations in a timely manner.

Fitch Rating's Short-Term Ratings are assigned to obligations whose initial maturity is viewed as "short term" based on market convention (a long-term rating can also be used to rate an issue with short maturity). Typically, this means a timeframe of up to 13 months for corporate, sovereign, and structured obligations and up to 36 months for obligations in U.S. public finance markets. A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. A rating ofF1 denotes an obligation of the highest short-term credit quality. It indicates the strongest intrinsic capacity for timely payment of financial commitments and may have an added "+" to denote any exceptionally strong credit feature. A rating of F2 denotes good short-term credit quality. It indicates a good intrinsic capacity for timely payment of financial commitments. A rating of F3 denotes fair short-term credit quality. It indicates that theintrinsic capacity for timely payment of financial commitments is adequate. A rating of B denotes an obligation that is of speculative short-term credit quality, indicating minimal capacity for timely payment of financial commitments as well as heightened vulnerability to near term adverse changes in financial and economic conditions. A rating of C denotes a high short-term default risk, and indicates that defaultis a real possibility. A rating of RD indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. RD is typically applicable to entity ratings only. A rating of D indicates a broad-based default event for an entity,or the default of a short-term obligation.

Item 29. Persons Controlled by or under Common Control with Registrant

The Trust through the American Beacon AHL Trend ETF, a separate series of the Trust, wholly owns and controls the American Beacon Cayman Trend Company, Ltd. ("Trend Subsidiary"), a company organized under the laws of the Cayman Islands. The Trend Subsidiary's financial statements will be included, on a consolidated basis, in the American Beacon AHL Trend ETF's annual and semi-annual reports to shareholders.

Item 30. Indemnification

Article XI of the Amended and Restated Declaration of Trust of the Trust provides that:

Limitation of Liability

Section 1.Provided they have exercised reasonable care and have acted under the reasonable belief that their actions are in the best interest of the Trust, the Trustees and officers of the Trust shall not be responsible for or liable in any event for neglect or wrongdoing of them or any officer, agent, employee or investment advisor of the Trust, and shall not be liable for errors of judgment or mistakes of fact or law, but nothing contained herein shall protect any Trustee or officer against any liability to which he or she would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

Indemnification

Section 2.

(a) Subject to the exceptions and limitations contained in paragraph (b) below:

(i) every person who is, or has been, a Trustee or officer or employee of the Trust or is or was serving at the request of the Trust as a trustee, director, officer, employee or agent of another organization in which the Trust has an interest as a shareholder, creditor or otherwise ("Covered Person") shall be indemnified by the Trust and each Series to the fullest extent permitted by law, including the 1940 Act and the rules and regulations thereunder as amended from time to time and interpretations thereunder, against liability and against all expenses reasonably incurred or paid by him or her in connection with any claim, action, suit or proceeding in which he or she becomes involved as a party or otherwise by virtue of his or her being or having been a Covered Person and against amounts paid or incurred by him or her in the settlement thereof;

(ii) subject to the provisions of this Section 2, each Covered Person shall, in the performance of his or her duties, be fully and completely justified and protected with regard to any act or any failure to act resulting from reliance in good faith upon the records, books and accounts of the Trust or, as applicable, any Series, upon an opinion or other advice of legal counsel, or upon reports made or advice given to the Trust or, as applicable, any Series, by any Trustee or any of its officers, employees, or a service provider selected with reasonable care by the Trustees or officers of the Trust, regardless of whether the person rendering such report or advice may also be a Trustee, officer or employee of the Trust or, as applicable, any Series.

(iii) as used herein, the words "claim," "action," "suit," or "proceeding" shall apply to all claims, actions, suits or proceedings (civil, criminal, investigative or other, including appeals), actual or threatened, and the words "liability" and "expenses" shall include, without limitation, attorneys' fees, costs, judgments, amounts paid in settlement, fines, penalties and other liabilities whatsoever.

(b) To the extent required under the 1940 Act and the rules and regulations thereunder as amended from time to time and interpretations thereunder, but only to such extent, no indemnification shall be provided hereunder to a Covered Person:

(i) who shall have been adjudicated by a court or body before which the proceeding was brought to be liable to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office; or

(ii) in the event of a settlement, unless there has been a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office: (A) by the court or other body approving the settlement; (B) by at least a majority of those Trustees who are neither interested persons of the Trust nor are parties to the matter based upon a review of readily available facts (as opposed to a full trial-type inquiry); or (C) by written opinion of independent legal counsel based upon a review of readily available facts (as opposed to a full trial-type inquiry).

(c) The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not be exclusive of or affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be such Covered Person and shall inure to the benefit of the heirs, executors and administrators of such Covered Person. Nothing contained herein shall affect any rights to indemnification to which any Covered Person or other person may be entitled by contract or otherwise under law or prevent the Trust from entering into any contract to provide indemnification to any Covered Person or other Person.

(d) To the extent that any determination is required to be made as to whether a Covered Person engaged in conduct for which indemnification is not provided as described herein, or as to whether there is reason to believe that a Covered Person ultimately will be found entitled to indemnification, the Person or Persons making the determination shall afford the Covered Person a rebuttable presumption that the Covered Person has not engaged in such conduct and that there is reason to believe that the Covered Person ultimately will be found entitled to indemnification.

(e) To the maximum extent permitted by applicable law, including Section 17(h) of the 1940 Act and the rules and regulations thereunder as amended from time to time and interpretations thereunder, expenses in connection with the preparation and presentation of a defense to any claim, action, suit or proceeding of the character described in paragraph (a) of this Section 2 shall be paid by the Trust or the applicable Series from time to time prior to final disposition thereof upon receipt of an undertaking by or on behalf of such Covered Person that such amount will be paid over by him or her to the Trust or a Series, as applicable, if it is ultimately determined that he or she is not entitled to indemnification under this Section 2; provided, however, that any such advancement will be made in accordance with any conditions required by the Commission.

According to Article XII, Section 1 of the Amended and Restated Declaration of Trust, nothing in the Amended and Restated Declaration of Trust shall be construed to make the Shareholders, either by themselves or with the Trustees, partners or members of a joint stock association. Trustees are not liable personally to any person extending credit to, contracting with or having any claim against the Trust, a particular Portfolio or the Trustees. A Trustee, however, is not protected from liability due to willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

Article V, Section 5 provides that, subject to the provisions of Article XI, the Trustees shall not be liable for any act or omission in accordance with certain advice of counsel or other experts or for failing to follow such advice. Article XI, Section 1 provides that the Trustees are not liable for errors of judgment or mistakes of fact or law, but a Trustee is not protected from liability due to willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office, for any act or omission in accordance with advice of counsel or other experts or for failing to follow such advice.

Numbered Paragraph 10 of the Management Agreement by and among American Beacon Funds, American Beacon Select Funds and American Beacon Advisors, Inc., dated June 23, 2016 provides that:

10. Limitation of Liability of the Manager.The Manager shall not be liable for any error of judgment or mistake of law or for any loss suffered by a Trust or any Fund in connection with the matters to which this Agreement relate except a loss resulting from the willful misfeasance, bad faith or gross negligence on its part in the performance of its duties or from reckless disregard by it of its obligations and duties under this Agreement. Any person, even though also an officer, partner, employee, or agent of the Manager, who may be or become an officer, Board member, employee or agent of a Trust shall be deemed, when rendering services to a Trust or acting in any business of a Trust, to be rendering such services to or acting solely for a Trust and not as an officer, partner, employee, or agent or one under the control or direction of the Manager even though paid by it. The U.S. federal and state securities laws impose liabilities on persons who act in good faith, and, therefore, nothing in this Agreement is intended to limit the obligations of the Manager under such laws. This Paragraph 10 does not in any manner preempt any separate written indemnification commitments made by the Manager with respect to any matters encompassed by this Agreement.

Numbered Paragraph 10 of the Management Agreement by and between American Beacon Select Funds and American Beacon Advisors, Inc., dated August 7, 2023 provides that:

10. Limitation of Liability of the Manager.The Manager shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Trust or any Fund, and its or their shareholders, in connection with the matters to which this Agreement relates, except a loss resulting from willful misfeasance, bad faith or gross negligence on its part in the performance of its duties or from reckless disregard by it of its obligations and duties under this Agreement. Any person, even though also an officer, director, partner, employee, or agent of the Manager, who may be or become an officer, Board member, employee or agent of the Trust shall be deemed, when rendering services to the Trust or any Fund or acting in any business of the Trust or such Fund, to be rendering such services to or acting solely for the Trust or such Fund and not as an officer, director, partner, employee, or agent or one under the control or direction of the Manager even though paid by it. The U.S. federal and state securities laws impose liabilities on persons who act in good faith, and, therefore, nothing in this Agreement is intended to limit the obligations of the Manager under such laws. This Paragraph 10 does not in any manner preempt any separate written indemnification commitments made by the Manager with respect to any matters encompassed by this Agreement, which shall survive the termination of this Agreement.

Numbered Paragraph 9 of the Investment Advisory Agreement with AHL Partners LLP provides that:

Neither the Manager nor the Trust shall have any liability to any Covered Person or any third party arising out of or related to this Agreement, provided however, the Manager agrees to indemnify and hold harmless, all Covered Persons against any and all losses, claims, damages, liabilities or litigation (including reasonable legal and other expenses), to which a Covered Person may become subject under the securities or commodities laws, any other federal or state law, at common law or otherwise, arising out of the Manager's responsibilities to any Covered Person which may be based upon any willful misfeasance, bad faith, gross negligence, or reckless disregard of, the Manager's obligations and/or duties under this Agreement by the Manager or by any of its directors, officers, employees, agents, or any affiliate acting on behalf of it.

The indemnification in this Section shall survive the termination of this Agreement.

Numbered Paragraph 9 of the Investment Advisory Agreement with GLG LLC, provides that:

9. Liability. The Adviser, its affiliates or their respective officers, directors, employees and agents (collectively, the "Covered Persons") shall have no liability to the Trust, its shareholders, the Manager or any third party arising out of or related to this Agreement, provided however, the Covered Persons agree to, and shall indemnify and hold harmless the Trust and its shareholders, the Manager, any affiliated person within the meaning of Section 2(a)(3) of the Investment Company Act, and each person, if any, who, within the meaning of Section 15 of the Securities Act, controls the Manager, against any and all losses, claims, damages, liabilities or litigation (including reasonable legal and other expenses), to which the Trust and its shareholders, the Manager or such affiliated person or controlling person may become subject under the securities or commodities laws, any other federal or state law, at common law or otherwise, arising out of or in connection with the performance of any Covered Person's responsibilities to the Trust and the Manager which may be based upon any willful misfeasance, bad faith, gross negligence, or reckless disregard of, any Covered Person's obligations and/or duties under this Agreement. The U.S. federal and state securities laws impose liabilities on persons who act in good faith, and therefore, nothing in this Agreement is intended to limit the obligations of any Covered Persons under such laws.

Neither the Manager nor the Trust shall have any liability to any Covered Person or any third party arising out of or related to this Agreement, provided however, the Manager agrees to indemnify and hold harmless, all Covered Persons against any and all losses, claims, damages, liabilities or litigation (including reasonable legal and other expenses), to which a Covered Person may become subject under the securities or commodities laws, any other federal or state law, at common law or otherwise, arising out of the Manager's responsibilities to any Covered Person which may be based upon any willful misfeasance, bad faith, gross negligence, or reckless disregard of, the Manager's obligations and/or duties under this Agreement by the Manager or by any of its directors, officers, employees, agents, or any affiliate acting on behalf of it.

The indemnification in this Section shall survive the termination of this Agreement.

Section 4.2 of the Distribution Agreement with Resolute Investment Distributors, Inc., provides that:

(a) Notwithstanding anything in this Agreement to the contrary, Resolute shall not be responsible for, and the Client shall on behalf of each applicable Fund or Class thereof, indemnify and hold harmless Resolute, its employees, directors, officers and managers and any person who controls Resolute within the meaning of section 15 of the Securities Act or section 20 of the Securities Exchange Act of 1934, as amended, (for purposes of this Section 4.2(a), "Resolute Indemnitees") from and against, any and all losses, damages, costs, charges, reasonable counsel fees, payments, liabilities and other expenses of every nature and character (including, but not limited to, direct and indirect reasonable reprocessing costs) arising out of or attributable to all and any of the following (for purposes of this Section 4.2(a), a "Resolute Claim")

(i) any material action (or omission to act) of Resolute or its agents taken in connection with this Agreement; provided, that such action (or omission to act) is taken in good faith and without willful misfeasance, negligence or reckless disregard by Resolute, or its affiliates, of its duties and obligations under this Agreement;

(ii) any untrue statement of a material fact contained in the Registration Statement or arising out of or based upon any alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, unless such statement or omission was made in reliance upon, and in conformity with, information furnished to the Client in connection with the preparation of the Registration Statement or exhibits to the Registration Statement by or on behalf of Resolute;

(iii) any material breach of the Clients' agreements, representations, warranties, and covenants in Sections 2.9 and 5.2 of this Agreement; or

(iv) the reliance on or use by Resolute or its agents or subcontractors of information, records, documents or services which have been prepared, maintained or performed by the Client or any agent of the Client, including but not limited to any Predecessor Records provided pursuant to Section 2.9(b).

(b) Resolute will indemnify, defend and hold the Client and their several officers and members of their Governing Bodies and any person who controls the Client within the meaning of section 15 of the Securities Act or section 20 of the Securities Exchange Act of 1934, as amended, (collectively, the "Client Indemnitees" and, with the Resolute Indemnitees, an "Indemnitee"), free and harmless from and against any and all claims, demands, actions, suits, judgments, liabilities, losses, damages, costs, charges, reasonable counsel fees and other expenses of every nature and character (including the cost of investigating or defending such claims, demands, actions, suits or liabilities and any reasonable counsel fees incurred in connection therewith), but only to the extent that such claims, demands, actions, suits, judgments, liabilities, losses, damages, costs, charges, reasonable counsel fees and other expenses result from, arise out of or are based upon all and any of the following (for purposes of this Section 4.2(c), a "Client Claim" and, with a Resolute Claim, a "Claim"):

(i) any material action (or omission to act) of Resolute or its agents taken in connection with this Agreement, provided that such action (or omission to act) is taken in good faith and without willful misfeasance, negligence or reckless disregard by Resolute, or its affiliates, of its duties and obligations under this Agreement.

(ii) any untrue statement of a material fact contained in the Registration Statement or any alleged omission of a material fact required to be stated or necessary to make the statements therein not misleading, if such statement or omission was made in reliance upon, and in conformity with, information furnished to the Client in writing in connection with the preparation of the Registration Statement by or on behalf of Resolute; or

(iii) any material breach of Resolute's agreements, representations, warranties and covenants set forth in Section 2.4 and 5.1 hereof.

(c) The Client or Resolute (for purpose of this Section 4.2(d), an "Indemnifying Party") may assume the defense of any suit brought to enforce any Resolute Claim or Client Claim, respectively, and may retain counsel chosen by the Indemnifying Party and approved by the other Party, which approval shall not be unreasonably withheld or delayed. The Indemnifying Party shall advise the other Party that it will assume the defense of the suit and retain counsel within ten (10) days of receipt of the notice of the claim. If the Indemnifying Party assumes the defense of any such suit and retains counsel, the other Party shall bear the fees and expenses of any additional counsel that they retain. If the Indemnifying Party does not assume the defense of any such suit, or if other Party does not approve of counsel chosen by the Indemnifying Party, or if the other Party has been advised that it may have available defenses or claims that are not available to or conflict with those available to the Indemnifying Party, the Indemnifying Party will reimburse any Indemnitee named as defendant in such suit for the reasonable fees and expenses of any counsel that the Indemnitee retains. An Indemnitee shall not settle or confess any claim without the prior written consent of the applicable Client, which consent shall not be unreasonably withheld or delayed.

(d) An Indemnifying Party's obligation to provide indemnification under this section is conditioned upon the Indemnifying Party receiving notice of any action brought against an Indemnitee within twenty (20) days after the summons or other first legal process is served. Such notice shall refer to the Person or Persons against whom the action is brought. The failure to provide such notice shall not relieve the Indemnifying Party of any liability that it may have to any Indemnitee except to the extent that the ability of the party entitled to such notice to defend such action has been materially adversely affected by the failure to provide notice.

(e) The provisions of this section and the parties' representations and warranties in this Agreement shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Indemnitee and shall survive the sale and redemption of any Shares made pursuant to subscriptions obtained by Resolute. The indemnification provisions of this section will inure exclusively to the benefit of each person that may be an Indemnitee at any time and their respective successors and assigns (it being intended that such persons be deemed to be third party beneficiaries under this Agreement).

Section 4.3 of the Distribution Agreement with Resolute Investment Distributors, Inc., provides that:

Notwithstanding anything in this Agreement to the contrary, except as specifically set forth below:

(a) Neither Party shall be liable for losses, delays, failure, errors, interruption or loss of data occurring directly or indirectly by reason of circumstances beyond its reasonable control, including, without limitation, acts of God; action or inaction of civil or military authority; public enemy; war; terrorism; riot; fire; flood; sabotage; epidemics; labor disputes; civil commotion; interruption, loss or malfunction of utilities, transportation, computer or communications capabilities; insurrection; or elements of nature;

(b) Neither Party shall be liable for any consequential, special or indirect losses or damages suffered by the other Party, whether or not the likelihood of such losses or damages was known by the Party;

(c) No affiliate, director, officer, employee, manager, shareholder, partner, agent, counsel or consultant of either Party shall be liable at law or in equity for the obligations of such Party under this Agreement or for any damages suffered by the other Party related to this Agreement;

(d) There are no third party beneficiaries of this Agreement;

(e) Each Party shall have a duty to mitigate damages for which the other Party may become responsible;

(f) The assets and liabilities of each Fund are separate and distinct from the assets and liabilities of each other Fund, and no Fund shall be liable or shall be charged for any debt, obligation or liability of any other Fund, whether arising under this Agreement or otherwise; and in asserting any rights or claims under this Agreement, Resolute shall look only to the assets and property of the Fund to which Resolute's rights or claims relate in settlement of such rights or claims; and

(g) Each Party agrees promptly to notify the other party of the commencement of any litigation or proceeding of which it becomes aware arising out of or in any way connected with the issuance or sale of Shares.

Section 3.4 of the Distribution Agreement with Foreside Financial Services, LLC, provides that:

The Distributor shall not be liable to the Adviser for any action taken or omitted by it in the absence of bad faith, willful misfeasance, gross negligence or reckless disregard by it (or its agents or employees) of its obligations and duties under this Agreement.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the foregoing or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Supplemental Limited Indemnification from the Manager

ABA shall indemnify and hold harmless Indemnitee, in his or her individual capacity, from and against any cost, asserted claim, liability or expense, including reasonable legal fees (collectively, "Liability") based upon or arising out of (i) any duty of ABA under the Management Agreement (including

ABA's failure or omission to perform such duty), and (ii) any liability or claim against Indemnitee arising pursuant to Section 11 of the Securities Act of 1933, as amended, Rule 10b-5 under the Securities Exchange Act of 1934, as amended, and any similar or related federal, state or common law statutes, rules or interpretations. ABA's indemnification obligations under this Letter Agreement shall be limited to civil and administrative claims or proceedings.
