PROSPECTUS

[XX XX, 2026]

This Prospectus contains important information you should know about investing, including information about risks. Please read it before you invest and keep it for future reference.

Fund shares are not individually redeemable. Fund shares are listed on  NYSE Arca, Inc. (the “Exchange”).

As with all exchange-traded funds, the Securities and Exchange Commission has not approved or disapproved these securities or determined if this Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Investment Objectives

The Fund’s investment objective is current income, with a secondary objective of capital appreciation.

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.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other 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:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund’s performance. The Fund’s portfolio turnover rate for the Fund’s most recent fiscal year is not provided because the Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in income-producing equity and equity-related investments. The Fund’s investments in equity and equity-related investments include U.S. common stocks, American Depositary Receipts (“ADRs”), U.S. dollar-denominated foreign stocks traded on U.S. exchanges, preferred stocks, convertible preferred stocks, and real estate investment trusts (“REITs”). An income-producing investment is one that has issued dividend income to investors within the past year.

The Fund’s investment sub-advisor, The London Company of Virginia, LLC (“The London Company”), emphasizes investments in profitable, financially stable, core companies that focus on generating high dividend income, are run by shareholder-oriented management with strong corporate governance practices and trade at reasonable valuations relative to their peers and market, which may include investments in growth companies. The London Company also seeks companies with high return on capital, consistent free cash flow generation, predictability and stability. The London Company employs an investment process with bottom-up, fundamental analysis and follows a strict sell discipline.

The Fund may invest in large- and mid-capitalization companies and will typically hold 30 to 40 issuers. The Fund may invest cash balances in other investment companies, including a government money market fund advised by the Manager, with respect to which the Manager also earns a management fee.

Principal Risks

There is no assurance that the Fund will achieve its investment objectives, and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of current income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund listed below are presented in alphabetical order and not in order of importance or potential exposure. Among other matters, this presentation is intended to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.  

Convertible Securities Risk
The value of a convertible security, including a convertible preferred security, typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in below investment grade debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. Convertible securities are subject to the risk that the credit standing of the issuer may have an effect on the convertible security‘s investment value. In addition, to the extent the Fund invests in convertible securities issued by mid-capitalization companies, it will be subject to the market risks of investing in such companies. The stocks of mid-capitalization companies may fluctuate more widely in price than the market as a whole and there may also be less trading in mid-capitalization stocks. Convertible securities are sensitive to movement in interest rates.

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

Dividend Risk
An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels or increase over time. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks. Securities that pay dividends may be sensitive to changes in interest rates and, as interest rates rise or fall, the prices of such securities may fall.

Equity Investments Risk
Equity securities represent ownership interests in companies and are subject to investment risk, issuer risk and market risk. In general, the values of stocks and other equity securities fluctuate, and sometimes widely fluctuate, in response to changes in a company’s financial condition as well as general market, economic and political conditions and other factors. The Fund may experience a significant or complete loss on its investment in an equity security. In addition, stock prices may be particularly sensitive to rising interest rates, which increase borrowing costs and the costs of capital.  The Fund may invest in the following equity securities, which may expose the Fund to the following additional risks:

Exchange-Traded Funds (“ETFs”) Risk  
As an ETF, the Fund is subject to the following risks:

2Prospectus – Fund Summary 

Back to Table of Contents

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

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

Growth Companies Risk
Growth companies are expected to increase their earnings at a certain rate. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. The Fund’s investments in growth companies may be more sensitive to company earnings and more volatile than the market in general primarily because their stock prices are based heavily on future expectations. If an assessment of the prospects for a company’s growth is incorrect, then the price of the company’s stock may fall or not approach the value placed on it. Growth company stocks may also lack the dividend yield that can cushion stock price declines in market downturns.

Investment Risk
An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Issuer Risk
The value of, and/or the return generated by, a security may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets.

Large-Capitalization Companies Risk
The securities of large market capitalization companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and, at times, such companies may be out of favor with investors. Many larger-capitalization companies also may be unable to attain the high growth rates of successful smaller companies, especially during periods of economic expansion.

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

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

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

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

Prospectus – Fund Summary3 

Back to Table of Contents

Mid-Capitalization Companies Risk
Investing in the securities of mid-capitalization companies involves greater risk and the possibility of greater price volatility, which at times can be rapid and unpredictable, than investing in larger-capitalization and more established companies. Since mid-capitalization companies may have narrower commercial markets and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity, and they can be particularly sensitive to changes in overall economic conditions, interest rates, borrowing costs and earnings.

New Fund Risk
The Fund had not commenced operations prior to the date of this Prospectus. The current performance of the Fund may not represent how it is expected to, or may, perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on the Fund’s performance. The Fund may also require a period of time before it is invested in securities that meet its investment objectives and policies and achieves a representative portfolio composition. Fund performance may be lower or higher during this “ramp-up” period, and may also be more volatile, than would be the case after the Fund is fully invested. Similarly, the Fund’s investment strategies may require a longer period of time to show returns that are representative of the strategies. As a new ETF, the Fund may experience low trading volume and wide bid-ask spreads.

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

Preferred Stock Risk
Preferred stocks are sensitive to movements in interest rates. Preferred stocks may be less liquid than common stocks and, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred stocks generally are payable at the discretion of an issuer and after required payments to bond holders. In certain situations, an issuer may call or redeem its preferred stock or convert it to common stock. The market prices of preferred stocks are generally more sensitive to actual or perceived changes in the issuer’s financial condition or prospects than are the prices of debt securities.

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

Value Stocks Risk
Value stocks are subject to the risk that their intrinsic or full value may never be realized by the market, that a stock judged to be undervalued may be appropriately priced, or that their prices may decline. Although value stocks tend to be inexpensive relative to their earnings, they can continue to be inexpensive for long periods of time. The Fund’s investments in value stocks seek to limit potential downside price risk over time; however, value stock prices still may decline substantially. In addition, the Fund may produce more modest gains as a trade-off for this potentially lower risk. The Fund’s investment in value stocks could cause the Fund to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

Fund Performance

Performance information will be available in the Prospectus after the Fund has been in operation for one full calendar year. When available, performance for the Fund can be accessed on the Fund’s website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund. Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer and may not be purchased or redeemed directly with the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (the “Exchange”). Shares may be purchased and redeemed from the Fund only in Creation Units of 25,000 shares, or multiples thereof, at NAV. As a practical matter, only institutions and large investors, such as market makers or other large broker-dealers, purchase or redeem Creation Units. Most investors will buy and sell shares of the Fund

on the Exchange. Individual shares can be bought and sold throughout the trading day like other publicly traded securities through a broker-dealer on the Exchange. These transactions do not involve the Fund. The price of an individual Fund share is based on market prices, which may be different from its NAV. As a result, the Fund’s shares may trade at a price greater than the NAV (at a premium) or less than the NAV (at a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (“bid”) and the lowest price a seller is willing to accept for shares of the Fund (“ask”) when buying or selling shares in the secondary market (the “bid-ask spread”). Most investors will incur customary brokerage commissions and charges when buying or selling shares of the Fund through a broker-dealer.

Recent information regarding the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads, is available on the Fund’s website at [www.americanbeaconfunds.com/products/etfs/american-beacon-The-London-Company-Income-Equity-ETF/].

Tax Information

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

Payments to Broker-Dealers and Other Financial Intermediaries

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

Additional Information About the Fund

To help you better understand the Fund, this section provides a detailed discussion of the Fund’s investment policies, its principal strategies, its principal risks, and performance index. However, this Prospectus does not describe all of the Fund’s investment practices. Capitalized terms that are not otherwise defined are defined in Appendix A. For additional information, please see the Fund’s SAI, which is available at www.americanbeaconfunds.com or by contacting us via telephone at 1-833-471-3562, by U.S. mail at the Fund’s Distributor, Foreside Financial Services, LLC, 190 Middle Street, Suite 301, Portland, Maine 04101, or by e-mail at  [email protected].

Additional Information About Investment Policies and Strategies

Investment Objectives

The Fund’s investment objective is current income, with a secondary objective of capital appreciation.

The Fund’s investment objectives are “non-fundamental,” which means that it may be changed by the Fund’s Board without the approval of Fund shareholders.

80% Investment Policy

The Fund has a non-fundamental policy to invest under normal circumstances at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in income-producing equity and equity-related investments.

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  objectives.

Additional Information About the Management of the Fund

The Fund has retained American Beacon Advisors, Inc. to serve as its Manager. The Manager may allocate the assets of the  Fund among different sub-advisors. The Manager provides or oversees the provision of all administrative, investment advisory and portfolio management services to the  Fund. The Manager:

The assets of the Fund are currently allocated by the Manager to one sub-advisor, The London Company of Virginia, LLC (“The London Company”).  The London Company has full discretion to purchase and sell securities for the Fund in accordance with the Fund’s objectives, policies, restrictions and more specific strategies provided by the Manager. The Manager oversees the sub-advisor but does not reassess individual security selections made by the sub-advisor for the  Fund.

In the future, the Manager may allocate the Fund’s assets to a different sub-advisor, and/or to one or more additional sub-advisors. The  Fund operates in a manager-of-managers structure. 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

Prospectus – Additional Information About the Fund5 

Back to Table of Contents

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.

Additional Information About Investments

This section provides more detailed information regarding certain of the Fund’s principal investment strategies as well as information regarding the Fund’s strategy with respect to investment of cash balances.

Cash Management
To gain market exposure on cash balances held in anticipation of liquidity needs or to reduce market exposure in anticipation of liquidity needs, the Fund may utilize the following investments:

Convertible Securities
Convertible securities, including convertible preferred securities, include corporate bonds, notes, preferred stock or other securities that may be converted into or exchanged for a prescribed amount of common stock or other equity securities of the same or a different issuer within a particular period of time at a specified price or formula. The conversion may occur automatically upon the occurrence of a predetermined event or at the option of either the issuer or the security holder. A convertible security may be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by the Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying common stock, or sell it to a third party. 

While typically providing a fixed-income stream, a convertible security also gives an investor the opportunity, through its conversion feature, to participate in the capital appreciation of the issuing company depending upon a market price advance in the convertible security's underlying common stock. However, convertible securities generally have less potential for gain or loss than common stocks. A convertible security entitles the holder to receive interest paid or accrued on debt or dividends paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. While convertible securities generally offer lower interest or dividend yields than non- convertible debt securities of similar quality, generally the yields are higher than the underlying common stock, and convertible securities enable the investor to benefit from increases in the market price of the underlying common stock. Because of this higher yield, convertible securities generally sell at prices above their "conversion value," which is the current market value of the stock to be received upon conversion. The difference between this conversion value and the price of convertible securities will vary over time depending on changes in the value of the underlying common stocks and interest rates.

 While no securities investment is without some risk, investments in convertible securities generally entail less risk than the issuer's common stock, although the extent to which such risk is reduced depends in large measure upon the degree to which the convertible security sells above its value as a fixed-income security. The market value of convertible securities tends to decline as interest rates increase and, conversely, to increase as interest rates decline. Holders of convertible securities have a claim on the assets of the issuer prior to the common stockholders, but may be subordinated to holders of similar non-convertible securities of the same issuer. Because of the conversion feature, certain convertible securities may be considered equity equivalents.

Equity Investments
The  Fund’s equity investments may include:  

Other Investment Companies
The  Fund, at times, may invest in shares of other investment companies. The Fund may invest in securities of an investment company advised by the Manager and/or a sub-advisor, with respect to which the Manager and/or sub-advisor also receives a management or advisory fee. Investments in the securities of other investment companies may involve duplication of advisory fees and certain other expenses. By investing in another investment company, the Fund becomes a shareholder of that investment company. As a result, Fund shareholders indirectly will bear the Fund’s proportionate share of the fees and expenses paid by shareholders of the other investment company, in addition to the fees and expenses Fund shareholders directly bear in connection with the Fund’s own operations. These other fees and expenses, if applicable, are reflected as Acquired Fund Fees and Expenses and are included in the Fees and Expenses Table for the Fund in this Prospectus. Investment in other investment companies may involve the payment of substantial premiums above the value of such issuer’s portfolio securities.

Preferred Stock
Preferred stock blends the characteristics of a bond and common stock. It can offer the higher yield of a bond and has priority over common stock in equity ownership, but it does not have the seniority of a bond and its participation in the issuer’s growth may be limited. Preferred stock has preference over common stock in the receipt of dividends and in any residual assets after payment to creditors should the issuer be dissolved. Although the dividend is typically set at a fixed annual rate, in some circumstances it can be variable, changed or omitted by the issuer. Preferred stock may pay fixed or adjustable

rates of return. Preferred stock dividends may be cumulative or noncumulative, fixed, participating, auction rate or other. Preferred stock may have mandatory sinking fund provisions, as well as provisions that allow the issuer to redeem or call the stock.  

Additional Information About Risks

The greatest risk of investing in an ETF is that its returns will fluctuate and you could lose money. The following section provides additional information regarding 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.

Convertible Securities Risk
The conversion value of a convertible security, including a convertible preferred security, is the market value that would be received if the convertible were converted to its underlying common stock. The value of a convertible security typically increases or decreases with the price of the underlying common stock. When conversion value is substantially below investment value, the convertible’s price tends to be influenced more by its yield, so changes in the price of the underlying common stock may not have as much of an impact. Conversely, the convertible’s price tends to be influenced more by the price of the underlying common stock when conversion value is comparable to or exceeds investment value. In general, a convertible security is subject to the market risks of stocks, and its price may be as volatile as that of the underlying stock when the underlying stock’s price is high relative to the conversion price. A convertible security also is subject to the market risks of debt securities, and is particularly sensitive to changes in interest rates, when the underlying stock’s price is low relative to the conversion price. The investment value of a convertible is based on its yield and tends to decline as interest rates increase. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk, and there is a risk that the credit standing of the issuer may have an effect on the convertible security’s investment value. Because their value can be influenced by many different factors, convertible securities generally have less potential for gain or loss than the underlying common stocks. Securities that are convertible other than at the option of the holder generally do not limit the potential for loss to the same extent as securities that are convertible at the option of the holder. Many convertible securities have credit ratings that are below investment grade (commonly known as “junk bonds”) and are subject to the same risks as an investment in lower-rated debt securities. Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. The credit rating of a company’s convertible securities is generally lower than that of its non-convertible debt securities. Convertible securities are normally considered “junior” securities — that is, the company usually must pay interest on its non-convertible debt securities before it can make payments on its convertible securities. If the issuer stops paying interest or principal, convertible securities may become worthless and the Fund could lose its entire investment. In addition, to the extent the Fund invests in convertible securities issued by mid-capitalization companies, it will be subject to the market risks of investing in such companies. The stocks of mid-capitalization companies may fluctuate more widely in price than the market as a whole and there may also be less trading in mid-capitalization stocks.

Cybersecurity and Operational Risk
Operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents may negatively impact the Fund, its service providers, and third-party fund distribution platforms, including the ability of shareholders to transact in  the Fund’s shares, and result in financial losses. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. A cybersecurity incident could, among other things, result in the loss or theft of shareholder data or funds, shareholders or service providers being unable to access electronic systems (also known as “denial of services”), loss or theft of proprietary information or financial data, the inability to process Fund transactions, interference with the Fund’s ability to calculate its NAV, impediments to trading, physical damage to a computer or network system, or remediation costs associated with system repairs. The occurrence of any of these problems could result in a loss of information, violations of applicable privacy and other laws, regulatory scrutiny, penalties, fines, reputational damage, additional compliance requirements, and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. Market events also may occur at a pace that overloads current information technology and communication systems and processes of the Fund, its service providers or other market participants, such as third-party distribution platforms, which could impact the ability of the Fund to conduct operations or of shareholders to transact the Fund’s shares.

The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid or mitigate risks that could lead to problems discussed above. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and it is not possible for the Manager, other Fund service providers, or third-party fund distribution platforms to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Recent geopolitical tensions may increase the scale and sophistication of deliberate attacks, particularly those from nation-states or from entities with nation-state backing. The  Fund cannot control the cybersecurity plans and systems of its service providers, its counterparties, third-party fund distribution platforms,  or the issuers of securities in which the Fund invests. The issuers of the Fund’s investments are likely to be dependent on computers for their operations and require ready access to their data and the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of the Fund’s investments, leading to significant loss of value.

Dividend Risk
The  Fund’s investments in dividend-paying stocks could cause the  Fund to underperform funds that invest without consideration of a company’s track record of paying dividends. An issuer of stock held by the  Fund may choose not to declare a dividend or the dividend rate might not remain at current levels or increase over time. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks. In addition, stocks of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other stocks, and a sharp rise in interest rates or an economic downturn could cause a company to unexpectedly reduce or eliminate its dividend. Securities that pay dividends may be sensitive to changes in interest rates, and as interest rates rise, the prices of such securities may fall. At times, the  Fund may not be able to identify dividend-paying stocks that are attractive investments. The income received by the  Fund will also fluctuate due to the amount of dividends that companies elect to pay.

Equity Investments Risk
Equity securities represent ownership interests in companies and  are subject to investment risk, issuer risk and market risk. In general, the values of stocks and other equity securities fluctuate, and sometimes widely fluctuate, in response to changes in a company’s financial condition as well as general market, economic and political conditions and other factors. The Fund may experience a significant or complete loss on its investment in an equity security. In addition, stock prices may be particularly sensitive to rising interest rates, which increase borrowing costs and the costs of capital.  The Fund may invest in the following equity securities, which may expose the Fund to the following additional risks:

Exchange-Traded Funds (“ETFs”) Risk
As an ETF, the  Fund is subject to the following risks:

Focused Holdings Risk
Because the  Fund may have a focused portfolio of fewer companies, the increase or decrease of the value of a single stock may have a greater impact on the  Fund’s NAV and total return when compared to other funds. Although a focused portfolio has the potential to generate attractive returns over time, it also may increase the  Fund’s volatility.

Foreign Exposure Risk
Exposure to non-U.S. issuers carries potential risks not associated with exposure to U.S. issuers. Such risks may include, but are not limited to: (1) political and financial instability, (2) less liquidity, (3) greater volatility, and (4) different government regulation of issuers. To the extent the Fund exposes a significant portion of its assets to securities of non-U.S. issuers domiciled in a single country or region, it is more likely to be affected by events or conditions of that country or region. The Fund’s exposure to a non-U.S. issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with that country, including tariffs, trade disputes or the imposition of economic and other sanctions by the U.S. or another country against a particular country, as well as competition from subsidized foreign competitors with lower production costs. There may be restrictions on the flow of international capital, including the possible seizure or nationalization of the assets of non-U.S. issuers to which the Fund is exposed. Global economic and financial markets have become increasingly interconnected and conditions (including recent volatility, terrorism, war and political instability) and events (including natural disasters) in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

Growth Companies Risk
Growth companies are those that are expected to have the potential for above-average or rapid growth. Growth companies are expected to increase their earnings at a certain rate. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. The Fund’s investments in growth companies may be more sensitive to company earnings and more volatile than the market in general primarily because their stock prices are based heavily on future expectations. If an assessment of the prospects for a company’s growth is incorrect, then the price of the company’s stock may fall or not approach the value placed on it. Growth company stocks may lack the dividend yield that can cushion stock price declines in market downturns. Growth companies may have limited operating histories and greater business risks, and their potential for profitability may be dependent on regulatory approval of their products or regulatory developments affecting certain sectors, which could have an adverse impact upon growth companies’ future growth and profitability. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment. The Fund’s growth style could cause it to underperform funds that use a value or non-growth approach to investing or have a broader investment style.

Investment Risk
An investment in the  Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The  Fund should not be relied upon as a complete investment program. The market price of the  Fund fluctuates, which means that when you sell your shares of the  Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the  Fund.

Issuer Risk
The value of, and/or the return generated by, a security may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets. When the issuer of a security implements strategic initiatives, including mergers, acquisitions and dispositions, there is the risk that the market response to such initiatives will cause the share price of the issuer’s securities to fall. An individual security may be more volatile, and may perform differently, than the market as a whole.

Large-Capitalization Companies Risk
The securities of large market capitalization companies may underperform other segments of the market, in some cases for extended periods of time, because such companies may be less responsive to competitive challenges and opportunities, such as changes in technology and consumer tastes, and, at times, such companies may be out of favor with investors. Large market capitalization companies generally are expected to be less volatile than companies with smaller market capitalizations. However, large market capitalization companies may be unable to attain the high growth rates of successful smaller companies, especially during periods of economic expansion, and may instead focus their competitive efforts on maintaining or expanding their market share.

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. 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. 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. The financial markets generally move in cycles, with periods of rising prices followed by periods of declining prices. The value of your investment may reflect these fluctuations. During a general

Prospectus – Additional Information About the Fund9

downturn in the securities markets, multiple asset classes may decline in value simultaneously. 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. 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. 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 10-15 years, 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  cybersecurity incidents, have led, and in the future may continue to lead, to general instability in world economies and markets and reduced liquidity in securities, which may negatively affect the value of your investment. 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.  

Policies established by the  U.S. government and/or Federal Reserve and economic and political circumstances within the U.S. and abroad, such as inflation, changes in interest rates, recessions, changes in government leadership, a government’s inability to agree on a budget, high public debt, the threat or occurrence of a federal government shutdown and threats or the occurrence of a failure to increase the federal government’s debt limit, which could result in a default on the government’s obligations, may 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. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

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.

Mid-Capitalization Companies Risk
Investments in mid-capitalization companies generally involve greater risks and the possibility of greater price volatility, which at times can be rapid and unpredictable, than investments in larger, more established companies. Mid-capitalization companies often have narrower commercial markets and more limited operating history, product lines, and managerial and financial resources than larger, more established companies. As a result, performance can be more volatile and they may face greater risk of business failure, which could increase the volatility of the Fund’s portfolio. Generally, the smaller the company size, the greater these risks. Additionally, mid-capitalization companies may have less market liquidity than large-capitalization companies, and they can be sensitive to changes in overall economic conditions, interest rates, borrowing costs and earnings.

New Fund Risk
The Fund had not commenced operations prior to the date of this Prospectus. The current performance and expenses of the Fund may not represent how it is expected to, or may, perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on the Fund’s performance. The Fund’s shareholder fees and annual fund operating expenses may also be higher initially than after it has fully implemented its investment strategies and attracted sufficient assets to achieve investment and trading efficiencies. The Fund may also require a period of time before it is invested in securities that meet its investment objectives and policies and achieves a representative portfolio composition. Fund performance may be lower or higher during this “ramp-up” period, and may also be more volatile, than would be the case after the Fund is fully invested. Similarly,  the Fund’s investment strategies may require a longer period of time to show returns that are representative of the strategies.

Other Investment Companies Risk
To the extent that the  Fund invests in shares of other registered investment companies, the  Fund will indirectly bear the fees and expenses, including, for example, advisory and administrative fees, charged by those investment companies in addition to the  Fund’s direct fees and expenses. If the Fund invests in other investment companies, the Fund may receive distributions of taxable gains from portfolio transactions by that investment company and may recognize taxable gains from transactions in shares of that investment company, which could be taxable to the Fund’s shareholders when distributed to them. The  Fund must rely on the investment company in which it invests to achieve its investment objectives. If the investment company fails to achieve its investment  objectives, the value of  the  Fund’s investment may decline, adversely affecting the  Fund’s performance. To the extent the  Fund invests in other investment companies that invest in equity securities, fixed-income securities and/or foreign securities, or that track an index, the  Fund is subject to the risks associated with the underlying investments held by the investment company or the index fluctuations to which the investment company is subject.   The  Fund will be subject to the risks associated with investments in those companies, including but not limited to the following:

Preferred Stock Risk
Preferred stocks, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. If interest rates rise, the dividend on preferred stocks may be less attractive, causing the price of preferred stocks to decline. Preferred stocks may have mandatory sinking fund provisions, as well as provisions for their call or redemption prior to maturity, which can have a negative effect on their prices when interest rates decline. Preferred stocks may be less liquid than common stocks and, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred stocks generally are payable at the discretion of an issuer and after required payments to bond holders. In certain situations, an issuer may call or redeem its preferred stock or convert it to common stock. The market prices of preferred stocks are generally more sensitive to actual or perceived changes in the issuer’s financial condition or prospects than are the prices of debt securities. Issuers may threaten preferred stockholders with the cancellation of all dividends and liquidation preference rights in an attempt to force their conversion to less secure common stock. Certain preferred stocks are equity securities because they do not constitute a liability of the issuer and therefore do not offer the same degree of protection of capital or continuation of income as debt securities. The rights of preferred stock on distribution of a corporation’s assets in the event of its liquidation are generally subordinated to the rights associated with a corporation’s debt securities. Therefore, in the event of an issuer’s bankruptcy, there is substantial risk that there will be nothing left to pay preferred stockholders after payments, if any, to bondholders have been made. Preferred stocks may also be subject to credit risk.

Prospectus – Additional Information About the Fund11

Securities Selection Risk
Securities selected for the Fund may decline substantially in value or may not perform to expectations. Judgments about the attractiveness, value and anticipated price movements of a security or asset class may be incorrect, and there is no guarantee that securities will perform as anticipated. The value of a security can be more or less volatile than the market as a whole, and the  Fund’s strategy may fail to produce the intended results. This could result in the Fund’s underperformance compared to other funds with similar investment objectives.

Value Stocks Risk
Investments in value stocks are subject to the risk that their intrinsic or full value may never be realized by the market, that a stock judged to be undervalued may be appropriately priced, or that their prices may decline. This may result in the value stocks’ prices remaining undervalued for extended periods of time and they may not ever realize their intrinsic or full value. While the Fund’s investments in value stocks seek to limit potential downside price risk over time, value stock prices still may decline substantially. In addition, the Fund may produce more modest gains as a trade-off for this potentially lower risk. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment. The Fund’s performance also may be affected adversely if value stocks become unpopular with, or lose favor among, investors. The Fund’s value style could cause it to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

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 of Resolute 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.

Under the Fund’s management agreement with the Manager (the “Management Agreement”), the Manager has agreed to pay all expenses of the Fund, except for the management fee payments to the Manager under the Management Agreement (also known as a “unitary advisory fee”), acquired fund fees and expenses, brokerage commissions and issue and transfer taxes relating to the purchase and sale of portfolio holdings, securities lending fees, expenses associated with securities sold short, costs, expenses or losses arising out of any liability or claim asserted against the Trust or Fund for violation of any law, distribution and service fees pursuant to a Rule 12b-1 plan (if any), all costs associated with proxies and shareholder meetings, except meetings related to changes to the Management Agreement, the election of any Board member who is an “interested person” of the Trust as defined in Section 2(a)(19) of the Investment Company Act, and/or other matters that directly benefit the Manager, taxes and governmental fees, and extraordinary expenses (including related fees and disbursements of counsel).

The Fund’s Management Agreement with the Manager provides for the Fund to pay the Manager an annualized management fee equal to  0.67% of the Fund’s average daily net assets that is calculated and accrued daily.

As compensation for services provided by the Manager in connection with securities lending activities conducted by the Fund, the lending Fund pays to the Manager, with respect to cash collateral posted by borrowers, a fee of 10% of the net monthly investment income (the income earned in the form of interest, dividends and realized capital gains from the investment of cash collateral, plus any negative rebate fees paid by borrowers, less the rebate amount paid to borrowers as well as related expenses) and, with respect to collateral other than cash, a fee up to 10% of loan fees and demand premiums paid by borrowers. The SEC has granted exemptive relief that permits the Fund to invest cash collateral received from securities lending transactions in shares of one or more private or registered investment companies managed by the Manager.  

As of the date of this Prospectus, the Fund does not intend to engage in securities lending activities.

A discussion of the Board’s consideration and approval of the Management Agreement between the Trust, on behalf of the  Fund and the Manager and the Investment Advisory Agreement between the Manager and the  sub-advisor will be available in Item 11 of the Fund’s Form N-CSR as filed with the SEC for the fiscal period ending  [February 28, 2027].

The Sub-Advisor

Set forth below is a brief description of the Sub-Advisor and the portfolio managers with joint and primary responsibility for the day-to-day management of the Fund. The Fund’s SAI provides additional information about the portfolio managers, including other accounts they manage, their ownership in the Fund and their compensation.

THE LONDON COMPANY OF VIRGINIA, LLC (‘‘The London Company’’), 1800 Bayberry Court, Suite 301, Richmond, Virginia 23226, is an investment advisory firm founded in 1994 and is majority employee owned. As of [XX XX, 2026] The London Company had $[XX] billion in assets under management. 

Stephen M. Goddard CFA, Managing Principal, CIO and Co-Lead Portfolio Manager, founded The London Company in 1994 and has served in this capacity since founding the company. Previously, he held Senior Portfolio Management positions at CFB Advisory and Flippin, Bruce & Porter. He has over 25 years of investment experience.

J. Brian Campbell CFA, Principal and Portfolio Manager. He has served as Portfolio Manager since he joined The London Company in 2010. Prior to joining The London Company, he was a Portfolio Manager and the Director of Research at Hilliard Lyons Capital Management from 2004 to 2010.

Sam Hutchings, CFA, Principal and Co-Lead Portfolio Manager, joined the London Company in 2015. He has served as a Portfolio Manager since 2018. Prior to joining The London Company, he was a Research Associate with Eaton Vance and a Senior Consultant at FactSet Research Systems. He has over 10 years of investment experience.

Prior Performance of Similar Accounts

The London Company maintains a composite (the “Composite”) of all accounts that have been managed by The London Company using substantially similar investment objectives, policies and strategies in all material respects as those of the Fund, which has an inception date of December 31, 1999. The Composite includes the American Beacon The London Company Income Equity Fund (“London Company Mutual Fund”), an open-end mutual fund. The performance information has been provided by The London Company and includes a comparison of the Composite’s return to a broad-based securities market index, which is the Fund’s benchmark and the benchmark of the London Company Mutual Fund, for the periods indicated.

Performance information for the Fund has not been provided because the Fund had not commenced operations as of the date of this Prospectus. The performance of the Composite does not represent the historical performance of the Fund. The other accounts in the Composite are separate and distinct from the Fund, and the performance of the Composite should not be considered indicative of the past or future performance of the Fund, nor should it be considered a substitute for the Fund’s performance. Results may differ because of, among other things, differences in brokerage commissions and other trading expenses, account expenses, including management fees, the size of positions taken in relation to account size and diversification of securities, timing of purchases and sales, and availability of cash for new investments. In addition, all accounts in the Composite, other than The London Company Mutual Fund, are not registered mutual funds or ETFs and are not subject to the same types of expenses as the Fund, nor have they been subject to certain investment limitations, diversification requirements or other restrictions imposed by the Investment Company Act and the Internal Revenue Code of 1986, as amended, which, if applicable, may have adversely affected the performance results of the other accounts, and thus of the Composite. Notwithstanding these differences, the accounts in the Composite and the Fund are substantially similar from an investment perspective. The Composite includes all accounts managed by The London Company with substantially similar investment objectives, policies and strategies in all material respects to the  Fund.

The performance of the Composite is shown net of transaction costs, and gross of custodian and other fees charged to an account. For periods beginning January 1, 2009, returns are calculated net of The London Company's highest annual advisory fee of 0.75%. Returns prior to January 1, 2009 are calculated net of The London Company's actual management fees. Some of the accounts in the Composite pay a bundled fee, which includes custodian, consultant and management fees. Because of this fee arrangement, the returns for certain accounts in the Composite prior to January 1, 2009 could have been higher than what is shown below. There are no other fees or expenses associated with The London Company's services to the Composite accounts and, except for certain share classes of the London Company Mutual Fund, there are no sales loads for the other accounts. The 0.75% advisory fee applied is the highest advisory fee charged to any account in the Composite, and is applied monthly to the gross return at 1/12th the annual rate, which is 0.0625% per month. Returns are calculated and stated in U.S. dollars and include the reinvestment of all dividends. Prior to April 1, 2024, returns are calculated gross of withholding taxes on foreign dividends and interest. Starting April 1, 2024, performance is calculated net or gross of foreign withholding taxes on dividends and interest income, dependent on custodian data. The performance of the Composite has not been adjusted to reflect the expenses of the Fund. The Fund's total annual operating expenses are expected to be lower than the highest total fees and expenses charged to the accounts in the Composite for periods subsequent to January 1, 2009.

The London Company has provided the Composite performance information, which is calculated using a methodology that incorporates the time-weighted rate of return, which takes into account the timing of cash flows and removes the effect of significant external cash flows. The London Company defines a significant cash flow as a cash or securities inflow or outflow greater than 10% of the client account as of the prior month-end valuation. The calculation method for the Composite return differs from the standardized SEC method for calculating performance for registered investment companies and may result in an average annual total return that may be different than that derived from the SEC's standard methodology. The SEC standardized average annual total return is calculated assuming reinvestment of dividends and distributions and deduction of sales loads or charges.

The Calendar year-to-date total return of the Composite as of June 30, 2026 was [XX]%. The calendar year-to-date total return of the S&P 500® Index as of June 30, 2026 was [XX]%.

The Distributor

Foreside Financial Services, LLC, a wholly owned subsidiary of Foreside Financial Group, LLC (doing business as ACA Group) (“Distributor”) serves as the Fund’s distributor.

The Distributor distributes Creation Units for the Fund on a best efforts basis. Shares in less than Creation Units are not distributed by the Distributor, and the Distributor does not maintain a secondary market in the shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is 190 Middle Street, Suite 301, Portland, Maine 04101.

Valuation of Shares

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, which may differ from the Fund’s market price. Investors that purchase and sell the Fund in the secondary market will transact at market prices, which may be lower or higher than the NAV per share.

The NAV per share of the Fund’s shares is determined based on a pro rata allocation of the Fund’s investment income, expenses and total capital gains and losses. The Fund’s NAV per share is determined each business day as of the regular close of trading on the NYSE, which is typically 4:00 p.m. Eastern Time. However, if trading on the NYSE closes at a time other than 4:00 p.m. Eastern Time, the Fund’s NAV per share typically would still be determined as of the regular close of trading on the NYSE. The Fund does not price its shares on days that the NYSE is closed. Foreign exchanges may permit trading in foreign securities on days when the Fund is not open for business, which may result in the value of the Fund’s portfolio investments being affected at a time when you are unable to buy or sell shares.

Equity securities and certain derivative instruments that are traded on an exchange are valued based on market value. Certain derivative instruments (other than short-term securities) usually are valued on the basis of prices provided by a pricing service. The price of debt securities generally is determined using pricing services or quotes obtained from broker/dealers who may consider a number of inputs and factors, such as comparable characteristics, yield curve, credit spreads, estimated default rates, coupon rates, underlying collateral and estimated cash flow. Investments in mutual funds are valued at the closing NAV per share of the mutual funds on the day of valuation. Equity securities, including shares of closed-end funds and ETFs, are valued at the last sale price or official closing price.

The valuation of securities traded on foreign markets and certain fixed-income securities will generally be based on prices determined as of the earlier closing time of the markets on which they primarily trade, unless a significant event has occurred. When the Fund holds securities or other assets that are denominated in a foreign currency, the exchange rates as of 4:00 p.m. Eastern Time will normally be used.

Rule 2a-5 under the Investment Company Act (the “Valuation Rule”) 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 the Fund must fair value a security.

The Valuation Rule permits the Fund’s board to designate the Fund’s primary investment adviser as “valuation designee” to perform the Fund’s fair value determinations subject 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 Valuation Rule to perform fair value functions in accordance with the requirements of the Valuation Rule.

Securities may be valued at fair value, as determined in good faith and pursuant to the Manager’s procedures. For example, fair value pricing will be used when market quotations are not readily available or reliable, as determined by the Manager, such as for fixed-income securities and when: (i) trading for a security is restricted or stopped; (ii) a security’s trading market is closed (other than customary closings); or (iii) a security has been de-listed from a national exchange. A security with limited market liquidity may require fair value pricing if the Manager determines that the available price does not reflect the security’s true market value. In addition, if a significant event that the Manager determines to affect the value of one or more securities held by the Fund occurs after the close of a related exchange but before the determination of the Fund’s NAV per share, fair value pricing may be used on the affected security or securities. Securities of small-capitalization companies are also more likely to require a fair value determination using these procedures because they are more thinly traded and less liquid than the securities of larger capitalization companies. Securities may be fair valued as a result of significant events occurring after the close of the foreign markets in which the Fund invests. In addition, the  Fund may invest in illiquid securities requiring these procedures.

Attempts to determine the fair value of securities introduce an element of subjectivity to the pricing of securities. As a result, the price of a security determined through fair valuation techniques may differ from the price quoted or published by other sources and may not accurately reflect the market value of the security when trading resumes. If a reliable market quotation becomes available for a security formerly valued through fair valuation techniques, the Manager compares the new market quotation to the fair value price to evaluate the effectiveness of the Fund’s fair valuation procedures.

About Your Investment

Purchase and Redemption of Shares

Shares of the Fund may be purchased or redeemed directly from the Fund only in Creation Units or multiples thereof. Only a broker-dealer that enters into an Authorized Participant agreement with the Distributor (an “Authorized Participation Agreement”) may engage in creation and redemption transactions directly with the Fund. Purchases and redemptions directly with the Fund must follow the Fund’s procedures, and are subject to transaction fees, which are described in the SAI. Orders for such transactions may be rejected or delayed if they are not submitted in good order and subject to the other conditions set forth in this Prospectus and the SAI. Please see the SAI for more information about purchases and redemptions of Creation Units.

Once purchased (i.e., created) by an Authorized Participant, shares are listed on the Exchange and trade in the secondary market. When you buy or sell the Fund’s shares in the secondary market, you will pay or receive the market price. The price at which you buy or sell shares (i.e., the market price) may be more or less than the NAV of the shares. Unless imposed by your broker, there is no minimum dollar amount you must invest in the Fund and no minimum number of Shares you must buy. Shares can be bought and sold throughout the trading day like other publicly traded securities. Most investors will buy and sell shares through a broker and, thus, will incur customary brokerage commissions and charges when buying or selling shares. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

The secondary markets are closed on weekends and also are generally closed on the following holidays: New Year’s Day, Martin Luther King Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day, but may be closed at other times. When a  holiday  observed by the Exchange falls on a Saturday, the Exchange will not be open for business on the preceding Friday unless unusual business conditions exist, such as the ending of a monthly or yearly accounting period.

Investments by Registered Investment Companies

Section 12(d)(1) of the Investment Company Act restricts investments by investment companies in the securities of other investment companies, including shares of the Fund. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1) subject to compliance with Rule 12d1-4 under the Investment Company Act, including, in certain cases, that such investment companies enter into an agreement with the Fund.

Continuous Offering

The method by which Creation Units of Fund shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of shares are issued and sold by the Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act of 1933 (the “Securities Act”), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells the shares directly to customers or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the Investment Company Act. As a result, broker-dealer firms should note that dealers who are not “underwriters” but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions) and thus dealing with the shares that are part of an overallotment within the meaning of Section 4(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is only available with respect to transactions on a national exchange.

Dealers effecting transactions in the Fund’s shares, whether or not participating in this distribution, are generally required to deliver a prospectus. This is in addition to any obligation of dealers to deliver a prospectus when acting as underwriters.

Beneficial Ownership

The Depository Trust Company (“DTC”) serves as securities depository for the Fund’s shares. DTC, or its nominee, is the owner of record for all outstanding shares. Beneficial owners of the Fund’s shares are not entitled to have shares registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and are not considered the registered holder thereof. Accordingly, to exercise any rights of a holder of shares, each beneficial owner must rely on the procedures of: (i) DTC; (ii) the securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC (“DTC Participants”), and (iii) brokers, dealers, banks and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly, through which such beneficial owner holds its interests (“Indirect Participants”). The Trust understands that, under existing industry practice, in the event the Fund requests any action of holders of shares, or a beneficial owner desires to take any action that DTC, as the record owner of all outstanding shares, is entitled to take, DTC would authorize the DTC Participants to take such action and that the DTC Participants would authorize the Indirect Participants and beneficial owners acting through such DTC Participants to take such action and would otherwise act upon the instructions of beneficial owners owning through them. For more detailed information, see “Book Entry Only System” in the Fund’s Statement of Additional Information.

Payments to Financial Intermediaries

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. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by the Manager or its affiliates from their own resources, and constitute what it sometimes referred to as “revenue sharing.”

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.

Compensation received by a financial intermediary from 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 the development of technology platforms and reporting systems, data provision services, financial intermediaries making shares of the Fund available to sales representatives and/or customers of a fund supermarket platform or similar program sponsor, services provided in connection with such fund supermarket platforms and programs, or 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 and the prospect of receiving it may create conflicts of interest between the intermediary and its customers and may provide the financial intermediary with an incentive to recommend the shares of the Fund or another fund in the American Beacon Funds Complex over other potential investments, and may cause it to make decisions about the level of services provided to its customers based on the payments or other financial incentives it is eligible to receive. Similarly, the compensation may cause financial intermediaries to elevate the prominence of the Fund within their 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 or its affiliates, or any other fees, expenses, or commissions your financial intermediary may charge you in addition to those disclosed in this Prospectus.

Frequent Trading and Market Timing

The Trust’s Board has determined not to adopt policies and procedures designed to prevent or monitor for frequent purchases and redemptions of the Fund’s shares because the  Fund sells and redeems its shares at NAV only in Creation Units pursuant to the terms of an Authorized Participant Agreement between the Authorized Participant and the Distributor, and such direct trading between the Fund and Authorized Participants is critical to ensuring that the Fund’s shares trade at or close to NAV. Further, the vast majority of trading in Fund shares occurs on the secondary market, which does not involve the Fund directly and therefore does not cause the Fund to experience many of the harmful effects of market timing, such as dilution and disruption of portfolio management. In addition, the Fund imposes a transaction fee on Creation Unit transactions, which is designed to offset transfer and other transaction costs incurred by the

Prospectus – About Your Investment15 

Back to Table of Contents

Fund in connection with the issuance and redemption of Creation Units and may employ fair valuation pricing to minimize potential dilution from market timing. The  Fund reserves the right to reject any purchase order at any time and reserves the right to impose restrictions on disruptive, excessive, or short-term trading.

Distributions and Taxes

The Fund distributes most or all of its net earnings and realized gains, if any, each taxable year in the form of dividends from net investment income (“dividends”) on a monthly basis and distributions of realized net capital gains (“capital gains distributions”) and net gains from foreign currency transactions (sometimes referred to  below collectively as “other distributions”) on an annual basis (and dividends, capital gains distributions, and other distributions are sometimes referred to below collectively as “distributions”). Different tax treatment applies to different types of distributions (as described in the table under “Taxes”).

The Fund does not have a fixed dividend rate and does not guarantee that it will pay any distributions in any particular period. Any dividends are paid monthly, and capital gains distributions and other distributions are paid annually.

No dividend reinvestment service is provided by the Fund. Financial intermediaries may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of Fund shares for reinvestment of their dividend distributions. Beneficial owners should contact their financial intermediary to determine the availability and costs of the service and the details of participation therein. Financial intermediaries may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and net capital gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Distributions of Fund income are generally taxable to you regardless of the manner in which they are received or reinvested.

Taxes

Fund distributions are taxable to shareholders other than tax-qualified retirement plans and accounts and other tax-exempt investors. However, the portion of the Fund’s dividends derived from its investments in U.S. Government obligations, if any, is generally exempt from state and local income taxes. Fund dividends, except those that are “qualified dividend income” (as described below), are subject to federal income tax at the rates for ordinary income contained in the Internal Revenue Code. The following table outlines the typical status of transactions in taxable accounts:

To the extent distributions are attributable to net capital gain that the Fund recognizes they are subject to a 15% maximum federal income tax rate for individual and certain other non-corporate shareholders (each, an ‘‘individual’’) (20% for individuals with taxable income exceeding certain thresholds, which are indexed for inflation annually), regardless of how long the shareholder held his or her Fund shares. A portion of the dividends the Fund pays to individuals may be ‘‘qualified dividend income’’ (‘‘QDI’’) and thus eligible for the preferential rates, mentioned above,  that apply to net capital gain. QDI is the aggregate of dividends the Fund receives on shares of most domestic corporations (excluding most distributions from REITs) and certain foreign corporations with respect to which the Fund satisfies certain holding period and other restrictions. To be eligible for those rates, a shareholder must meet similar restrictions with respect to his or her Fund shares.

A portion of the dividends the Fund pays may also be eligible for the dividends-received deduction allowed to corporations (“DRD”), subject to similar holding period and other restrictions, but the eligible portion may not exceed the aggregate dividends the Fund receives from domestic corporations only.

A shareholder may realize a taxable gain or loss when selling shares. That gain or loss is treated as a short-term or long-term capital gain or loss, depending on how long the shares were held. Any capital gain an individual shareholder recognizes on a sale of Fund shares that have been held for more than one year will qualify for the 15% and 20% tax rates mentioned above.

An individual must pay a 3.8% tax on the lesser of (1) the individual’s ‘‘net investment income,’’ which generally includes distributions the Fund pays and net gains realized on the sale or exchange of Fund shares, or (2) the excess of the individual’s ‘‘modified adjusted gross income’’ over a threshold amount ($250,000 for married persons filing jointly and $200,000 for single taxpayers). This tax is in addition to any other taxes due on that income. A similar tax applies to estates and trusts. Shareholders should consult their own tax advisers regarding the effect, if any, this tax may have on their investment in Fund shares.

Each year, the Fund’s shareholders will receive tax information regarding Fund distributions and dispositions of Fund shares to assist them in preparing their income tax returns.

The Internal Revenue Code generally allows individuals and certain other non-corporate entities a deduction for 20% of (1) “qualified REIT dividends” and (2) “qualified publicly traded partnership income” (such as income from MLPs). Treasury regulations permit a RIC to pass the character of its qualified REIT dividends through to its shareholders provided certain holding period requirements are met. As a result, a shareholder in the Fund will be eligible to receive the benefit of the same 20% deduction with respect to the Fund’s REIT-based dividends as is available to an investor who directly invests in REITs. There currently is no similar pass-through of the 20% deduction with respect to a RIC’s qualified publicly traded partnership income.

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.

Taxes on Creations and Redemptions of Creation Units
A person who purchases a Creation Unit by exchanging securities in-kind generally will recognize a gain or loss equal to the difference between (i) the sum of the market value of the Creation Units at the time of the exchange and any net amount of cash received by the Authorized Participant in the exchange and (ii) the sum of the purchaser’s aggregate basis in the securities surrendered and any net amount of cash paid for the Creation Units. A person who redeems Creation Units and receives securities in-kind from the Fund will generally recognize a gain or loss equal to the difference between the redeemer’s basis in the Creation Units, and the aggregate market value of the securities received and any net cash received. The IRS, however, may assert that a loss realized upon an in-kind exchange of securities for Creation Units or an exchange of Creation Units for securities cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Persons effecting in-kind creations or redemptions should consult their own tax adviser with respect to these matters.

The Fund has the right to reject an order for Creation Units if the purchaser (or a group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of the Fund and if, pursuant to section 351 of the Internal Revenue Code, the Fund would have a basis in the deposit securities different from the market value of such securities on the date of deposit. The Fund also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determinations.

Additional Information

The Fund’s Board oversees generally the operations of the Fund. The Trust enters into contractual arrangements with various parties, including among others, the Fund’s manager, sub-advisor(s), custodian, transfer agent, and accountants, who provide services to the Fund. Shareholders are not parties to any such contractual arrangements, and those contractual arrangements are not intended to create in any shareholder any right to enforce them directly against the service providers or to seek any remedy under them directly against the service providers.

This Prospectus provides information concerning the Fund that you should consider in determining whether to purchase Fund shares. Neither this Prospectus nor the SAI is intended, or should be read, to be or create an agreement or contract between the Trust or the Fund and any investor, or to create any rights in any shareholder or other person other than any rights under federal or state law that may not be waived. Nothing in this Prospectus, the SAI or the Fund’s reports to shareholders is intended to provide investment advice and should not be construed as investment advice.

Distribution Plan

The Fund has adopted a Distribution Plan in accordance with Rule 12b-1 under the Investment Company Act, which allows the Fund to pay distribution and other fees for the sale of Fund shares and for other services provided to shareholders. The Plan also authorizes the use of any fees received by the Manager in accordance with the Management Agreement, and any fees received by the sub-advisor pursuant to its Investment Advisory Agreement, to be used for the sale and distribution of Fund shares. The Plan provides that the shares of the Fund may pay up to 0.25% per annum of the average daily net assets attributable to the shares, to the Manager (or another entity approved by the Board). Because these fees would be paid out of the Fund’s assets on an ongoing basis, over time these fees would increase the cost of your investment and may cost you more than paying other types of sales charges. There is no present intention of Fund shares paying, accruing, or incurring any Rule 12b-1 fees and Fund shares will not pay, accrue or incur any Rule 12b-1 fees until such time as approved by the Fund’s Board.

ORGANIZATION AND HISTORY OF THE FUND

The Fund is a separate series of the American Beacon Select Funds (the “Trust”), an open-end management investment company organized as a Massachusetts business trust on August 18, 1999. The Fund constitutes a separate investment portfolio with distinct investment objectives and a distinct purpose and strategy. The Fund is “diversified” as that term is defined by the Investment Company Act.

The Fund issues and redeems shares at net asset value (“NAV”) only in aggregations of a specified number of shares (“Creation Units”) in exchange for a “Basket” of cash and/or securities. The Fund generally issues and redeems Creation Units in exchange for a designated Basket of securities plus an amount of cash that the Fund specifies but may also issue and redeem Creation Units in exchange for a Basket of cash. Unlike mutual funds, shares are not individually redeemable.

Certain employees of the Fund’s sub-advisor, American Beacon Advisors, Inc. (the “Manager”) or the Manager’s affiliates are responsible for interacting with market participants that transact in Baskets for one or more Creation Units. As part of these discussions, these employees may discuss with a market participant the securities the Fund is willing to accept in connection with a purchase (also called a “creation”) of shares, and securities that the Fund will provide on a redemption of shares. These employees may also discuss portfolio holdings-related information with broker-dealers in connection with settling the Fund’s transactions, as may be necessary to conduct business in the ordinary course.

Shares of the Fund are listed on NYSE Arca, Inc. (the “Exchange”), a national securities exchange and trade in the secondary market, where most investors will buy and sell them at market prices that change throughout the day. Such market prices may be lower, higher or equal to NAV. Accordingly, when transacting in the secondary market, investors may pay more than NAV when purchasing shares and receive less than NAV when selling shares. Investors may also pay brokerage commissions and similar charges when purchasing and selling shares.

ADDITIONAL INFORMATION ABOUT INVESTMENT STRATEGIES AND RISKS

The Fund’s investment objectives, principal investment strategies, and principal risks are described in the Prospectus. This section contains additional information about the Fund’s investment policies and risks and types of investments the Fund may purchase. The composition of the Fund’s portfolio and the strategies that 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 objectives. 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. (See “Cover and Asset Segregation” disclosure below.)  

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.

Convertible Securities – Convertible securities include corporate bonds, notes, debentures, preferred stock or other securities that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula. Convertible securities generally have features of, and risks associated with, both equity and fixed-income instruments. As such, the value of most convertible securities will vary with changes in the price of, and will be subject to the risks associated with, the underlying common stock. Additionally, convertible securities are also subject to the risk that the issuer may not be able to pay principal or interest when due and the value of the convertible security may change based on the issuer's credit rating.

A convertible security entitles the holder to receive interest paid or accrued on debt or dividends paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion, such securities ordinarily provide a stream of income with generally higher yields than common stocks of the same or similar issuers, but lower than the yield on non-convertible debt. The value of a convertible security is a function of (1) its yield in comparison to the yields of other securities of comparable maturity and quality that do not have a conversion privilege and (2) its worth if converted to the underlying common stock. While no securities investment is without some risk, investments in convertible securities generally entail less risk than investments in the issuer's common stock, although the extent to which such risk is reduced depends in large measure upon the degree to which the convertible security sells above its value as a fixed- income security. Holders of convertible securities have a claim on the assets of the issuer senior to the common stockholders but may be subordinated to holders of similar non- convertible securities of the same issuer. If the convertible security's “conversion value,” which is the market value of the underlying common stock that would be obtained upon the conversion of the convertible security, is substantially below the “investment value,” which is the value of a convertible security viewed without regard to its conversion feature (i.e., strictly on the basis of its yield), the price of the convertible security is governed principally by its investment value. If the conversion value of a convertible security increases to a point that approximates or exceeds its investment value, the value of the security will be principally influenced by its conversion value. A convertible security will sell at a premium over its conversion value to the extent investors place value on the right to acquire the underlying common stock while holding an income-producing security.

The market value of convertible securities tends to decline as interest rates increase and, conversely, to increase as interest rates decline. While convertible securities generally offer lower interest or dividend yields than non-convertible debt securities of similar quality, they do enable the investor to benefit from increases in the market price of the underlying common stock. A convertible security may have a mandatory conversion feature or a call feature that subjects it to redemption at the option of the issuer at a price established in the security's governing instrument. If a convertible security held by the Fund is called for redemption the Fund will be required to convert it into the underlying common stock, sell it to a third party or permit the issuer to redeem the security. Any of these actions could have an adverse effect on the Fund's ability to achieve its investment objectives. Because of the conversion feature, certain convertible securities may be considered equity equivalents. 

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.

Cover and Asset Segregation —   The Fund may borrow money, make investments or employ trading practices that obligate the Fund, on a fixed or contingent basis, to deliver an asset or make a cash payment to another party in the future. The Fund will comply with rules and guidance from the SEC with respect to coverage of certain investments and trading practices. The Fund’s approach to asset coverage may vary depending on terms within its agreement with a counterparty. With respect to certain investments under the agreement, the Fund calculates the obligations of the parties to the agreement on a “net basis” (i.e., the two payment streams are netted out with the Fund receiving or paying, as the case may be, only the net amount of the two payments). Under such circumstances, the Fund’s current obligations will generally be equal only to the net amount to be paid by the Fund based on the relative values of the positions held by each party to the agreement. Earmarking or otherwise segregating a large percentage of the Fund’s assets could impede the management of the Fund’s portfolio or the Fund’s ability to meet redemption requests or other current obligations, because the Fund may be unable to promptly dispose of those assets.  

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, its service providers, third-party fund distribution platforms, and the issuers of the Fund’s investments may be prone to operational and information security risks resulting from cybersecurity incidents, including cyber-attacks. In general, cybersecurity 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 (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, the Manager, the sub-advisor, 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, result in violations of applicable privacy and other laws, 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 (also known as “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 or corrective measures, and such costs may be ongoing because threats of cyber-attacks are constantly evolving as cyber-attackers become more sophisticated and their techniques become more complex. Similar types of cybersecurity risks are also present for issuers of the Fund’s investments, which could result in material adverse consequences for such issuers and may cause the Fund 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. Furthermore, as a result of cyber-attacks, disruptions or failures, an exchange or market may close or issue trading halts on specific securities or the entire market, which may

result in the Fund being, among other things, unable to buy or sell certain securities or unable to accurately price its investments.  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 the  Fund’s 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. There are inherent limitations in risk management systems that seek to reduce the risks associated with cybersecurity incidents, including the possibility that risks may not have been adequately identified or prepared for, or that different or unknown threats may emerge in the future. Furthermore, the Fund does not control the  cybersecurity systems and plans of the issuers of the Fund’s investments, third party service providers, trading counterparties or any other service providers whose operations may affect the Fund or its shareholders. The use of cloud-based service providers could heighten or change these risks. In addition, remote and hybrid work arrangements by the Fund, the Manager or their service providers could increase all of the above risks, create additional data and information accessibility concerns, and make the Fund, the Manager or their service providers susceptible to operational disruptions, any of which could adversely impact their operations.

Equity Investments — The Fund may invest in the following equity securities:

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.

Foreign Investing —  The Fund may invest in U.S. dollar-denominated and non-U.S. dollar-denominated equity, debt and derivative instruments of foreign issuers and foreign branches of  U.S. banks. Foreign issuers are issuers organized and doing business principally outside the United States and include corporations, banks,  non-U.S. governments, and quasi-governmental organizations. While investments in foreign investments are intended to reduce risk by providing further diversification, such investments involve sovereign and other risks, in addition to the credit and market risks normally associated with domestic securities. These additional risks may include: the possibility of adverse political and economic developments (including political or social instability, nationalization, expropriation, or confiscatory taxation); the impact of economic, political, social, diplomatic or other conditions or events (including, for example, military confrontations and actions, war, other conflicts, terrorism, and disease/virus outbreaks and epidemics); the potentially adverse effects of unavailability of public information regarding issuers, less or less reliable information about the securities and business operations of foreign issuers, less governmental supervision and regulation of financial markets, reduced liquidity of certain financial markets, and the lack of uniform accounting, auditing, and financial reporting standards or the application of standards that are different or less stringent than those applied in the United States; different laws and customs governing securities purchases, tracking and custody; the difficulty of predicting international trade patterns and the possibility of exchange controls or limitations on the removal of funds or assets; and possibly more limited legal remedies and access to the courts available to enforce  the Fund’s rights as an investor. The prices of such securities may be more volatile than those of domestic securities. Non-U.S. equity securities may trade at price/earnings multiples higher than comparable U.S. securities, and such levels may not be sustainable. The economies of many of the countries in which the Fund may invest are not as developed as the U.S. economy, and

3

individual foreign economies can differ favorably or unfavorably from the U.S. economy in such respects as growth of gross national product, rate of inflation, capital reinvestment, resource self-sufficiency, and balance of payments position. Certain such economies may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments, the imposition of economic sanctions against a particular country or countries, changes in international trading patterns, trade barriers, and other protectionist or retaliatory measures. Individual foreign companies also may differ favorably or unfavorably from U.S. companies in the same industry.  

Foreign stock markets are generally not as developed or efficient as, and may be more volatile than, those in the United States. While growing in volume, they usually have substantially less trading volume than U.S. markets. As a result, foreign securities may trade with less frequency and in less volume than domestic securities and therefore may exhibit greater or lower price volatility. The Fund may be exposed to risks in the process of clearing and settling trades and the holding of securities by foreign banks, agents and depositories. Governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Additional costs associated with an investment in foreign securities may include higher custodial fees than apply to domestic custody arrangements and transaction costs of foreign currency conversions. Investments in emerging markets may be subject to greater custody risks than investments in more developed markets. Foreign markets also have different clearance and settlement procedures. In certain markets, there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. Trading practices, including those involving the release of assets in advance of payment, may involve increased risks in the event of a failed trade or the insolvency of a broker-dealer, and may involve substantial delays. Delays in settlement could result in temporary periods when a portion of the assets of the Fund is not invested and no return is earned thereon. The inability of the Fund to make intended security purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. Inability to dispose of portfolio securities due to settlement problems could result in losses to the Fund due to subsequent declines in value of the securities or, if the Fund has entered into a contract to sell the securities, could result in possible liability to the purchaser. In addition, certain foreign markets may institute share blocking, which is a practice under which an issuer’s securities are blocked from trading at the custodian or sub-custodian level for a specified number of days before and, in certain instances, after a shareholder meeting where a vote of shareholders takes place. The blocking period can last up to several weeks. Share blocking may prevent the Fund from buying or selling securities during this period, because during the time shares are blocked, trades in such securities will not settle. It may be difficult or impossible to lift blocking restrictions, with the particular requirements varying widely by country. As a consequence of these restrictions, the  sub-advisor, on behalf of the Fund, may elect not to vote proxies in markets that require share blocking. Interest rates prevailing in other countries may affect the prices of foreign securities and exchange rates for foreign currencies. Local factors, including the strength of the local economy, the demand for borrowing, the government’s fiscal and monetary policies, and the international balance of payments, often affect interest rates in other countries.  

Economic sanctions and other similar governmental actions could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell foreign securities, and thus may prevent the Fund from making investments or make the Fund’s investments in such securities less liquid or more difficult to value. In addition, as a result of economic sanctions, the Fund may be forced to sell or otherwise dispose of investments at inopportune times or prices, which could result in losses to the Fund and increased transaction costs. These conditions may be in place for a substantial period of time and enacted with limited advance notice to the Fund. The risks posed by sanctions against a particular foreign country, its nationals or industries or businesses within the country may be heightened to the extent the Fund invests significantly in the affected country or region or in issuers from the affected country that depend on global markets.

Investing in foreign currency denominated investments involves not only the special risks associated with investing in  non-U.S. issuers, as described above, but also the additional risks of adverse changes in foreign exchange rates and investment or exchange control regulations, which could prevent cash from being brought back to the United States. Additionally, dividends and interest payable on foreign securities (and gains realized on disposition thereof) may be subject to foreign taxes, including taxes withheld from those payments. Some governments may impose a tax on purchases by foreign investors of certain securities that trade in their country. Countries may amend or revise their existing tax laws, regulations and/or procedures in the future, possibly with retroactive effect. Changes in or uncertainties regarding the laws, regulations or procedures of a country could reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the after-tax profits of companies located in such countries in which the Fund invests, or result in unexpected tax liabilities for the Fund. Commissions on foreign securities exchanges are often at fixed rates and are generally higher than those negotiated commissions on U.S. exchanges, as are transaction costs,  although the sub-advisor endeavors to achieve the most favorable net results on portfolio transactions.

The Fund may also invest in foreign “market access” investments, such as participatory notes, low-exercise price options or warrants, equity-linked notes, or equity swaps. These investments may provide economic exposure to an issuer without directly holding its securities. For example, market access investments may be used where regulatory or exchange restrictions make it difficult or undesirable for the Fund to invest directly in an issuer’s common stock. Use of market access investments may involve risks associated with derivative investments, which are discussed in “Derivatives.”  Market access investments can be either exchange-traded or over-the-counter. Certain market access investments can be subject to the credit risk of both the underlying issuer and a counterparty. Holders of certain market access investments might not have voting, dividend, or other rights associated with shareholders of the referenced securities. Holders of market access investments might not have any right to make a claim against an issuer or counterparty in the event of their bankruptcy or other restructuring. It may be more difficult or time consuming to dispose of certain market access investments than the referenced security.

The Fund may be subject to the risk that its share price may be exposed to arbitrage attempts by investors seeking to capitalize on differences in the values of foreign securities trading on foreign exchanges that may close before the time the Fund’s net asset value is determined. If such arbitrage attempts are successful, the Fund’s net asset value might be diluted.

The use of fair value pricing in certain circumstances may help deter such arbitrage activities. The effect of such fair value pricing is that foreign securities may not be priced on the basis of quotations from the primary foreign securities market in which they are traded, but rather may be fair valued. As such, fair value pricing is based on subjective judgment, and it is possible that fair value may differ materially from the value realized on a sale of a foreign security. It is also possible that use of fair value pricing will limit an investment adviser’s ability to implement the Fund’s investment strategy (e.g., reducing the volatility of the Fund’s share price) or achieve its investment objectives.

Growth Companies — Growth companies are those that are expected to have the potential for above-average or rapid growth. Growth companies are expected to increase their earnings at a certain rate. When these expectations are not met or earnings decrease, the prices of these securities may decline, sometimes sharply, even if earnings showed an absolute increase. The Fund’s investments in growth companies may be more sensitive to company earnings and more volatile than the market in general primarily because their stock prices are based heavily on future expectations. If an assessment of the prospects for a company’s growth is incorrect, then the price of the company’s stock may fall or not approach the value placed on it. Growth company securities may lack the dividend yield that can cushion prices in market downturns. Growth companies may have limited operating histories and greater business risks, and their potential for profitability may be dependent on regulatory approval of their products or regulatory developments affecting certain sectors, which could have an adverse impact upon growth companies’ future growth and profitability. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment. The Fund’s growth style could cause it to underperform funds that use a value or non-growth approach to investing or have a broader investment style.

Interfund Lending — Pursuant to an order issued by the SEC, the Fund may participate in a credit facility whereby the Fund, under certain conditions, is permitted to lend money directly to and borrow directly from other funds under the Manager’s management for temporary purposes. The credit facility is administered by a credit facility team consisting of professionals from the Manager’s asset management, compliance, and accounting departments, who report on credit facility activities to the Board. The credit facility can provide a borrowing fund with savings at times when the cash position of the Fund is insufficient to meet temporary cash requirements. This situation could arise when shareholder redemptions exceed anticipated volumes and the Fund has insufficient cash on hand to satisfy such redemptions, or when sales of securities do not settle as expected, resulting in a cash shortfall for the Fund.  The credit facility provides a source of immediate, short-term liquidity pending settlement of the sale of portfolio securities. Although the credit facility may reduce the Fund’s need to borrow from banks, the Fund remains free to establish and utilize lines of credit or other borrowing arrangements with banks.

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.

Large-Capitalization Companies Risk — The securities of large market capitalization companies may underperform other segments of the market, in some cases, for extended periods of time. Such companies may be less responsive to competitive challenges and opportunities, such as changes in technology and consumer tastes, and, at times, such companies may be out of favor with investors. Large market capitalization companies generally are expected to be less volatile than companies with smaller market capitalizations. However, large market capitalization companies may be unable to attain the high growth rates of successful smaller companies, especially during periods of economic expansion, and may instead focus their competitive efforts on maintaining or expanding their market share.

Mid-Capitalization Companies Risk — Investing in the securities of mid-capitalization companies involves greater risk and the possibility of greater price volatility than investing in more established companies with larger capitalization. Since mid-capitalization companies may have limited operating history, product lines and financial resources, the securities of these companies may lack sufficient market liquidity and can be sensitive to expected changes in interest rates, borrowing costs and earnings.

Other Investment Company Securities and Exchange-Traded Products — Investments in the securities of other investment companies may involve duplication of advisory fees and certain other expenses. By investing in another investment company, the Fund becomes a shareholder of that investment company. As a result, Fund shareholders indirectly will bear the Fund’s proportionate share of the fees and expenses paid by shareholders of the other investment company, in addition to the fees and expenses Fund shareholders directly bear in connection with the Fund’s own operations.    Any such fees and expenses are reflected in the Fees and Expenses Table for the Fund in its Prospectus. To the extent the Fund invests in investment company securities advised by the Manager and/or a sub-advisor, shareholders could pay fees charged by the Manager and/or sub-advisor to such investment company. The Fund’s investment in securities of other investment companies, except for money market funds, is generally limited to (i) 3% of the total voting stock of any one investment company, (ii) 5% of the Fund’s total assets with respect to any one investment company and (iii) 10% of the Fund’s total assets in all investment companies in the aggregate.  In addition, the Fund is generally limited to selling 3% of its total voting stock to an investment company. However, the Fund may exceed these limits in reliance on a statutory exemption, the terms and conditions of an exemptive order from the SEC, or Rule 12d1-4 under the Investment Company Act. Such investments may be subject to various conditions, including limits on control and voting of acquired fund shares, required evaluations and findings by investment advisers, fund investment agreements, and/or limits on most three-tier fund structures. When the  Fund is an acquired fund relying on one of the aforementioned exemptions, it may be limited in its ability to invest in other investment companies (i.e., a three-tier fund structure).  

The Fund at times may invest in shares of other investment companies and exchange-traded products, which, in addition to the general risks of investments in other investment companies described above, include the following risks:

Preferred Stock — A preferred stock blends the characteristics of a bond and common stock. It can offer the higher yield of a bond and has priority over common stock in equity ownership but does not have the seniority of a bond, and its participation in the issuer’s growth may be limited. Preferred stock generally has preference over common stock in the receipt of dividends and in any residual assets after payment to creditors should the issuer be

dissolved. Because preferred stock is subordinate to bonds in the issuer’s capital structure, the value of preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Although the dividend is set at a fixed or variable rate, in some circumstances it can be changed or omitted by the issuer. Preferred stockholders may have certain rights if dividends are not paid but generally have no legal recourse against the issuer, and may suffer a loss of value as a result. Preferred stocks are subject to the risks associated with other types of equity securities, as well as additional risks, such as credit risk, interest rate risk, potentially greater volatility and risks related to the deferral of dividend payments, the non-cumulative payment of dividends (in which omitted or deferred dividends are not subsequently paid), subordination, liquidity, limited voting rights, and special redemption rights. The market prices of preferred stock are generally more sensitive to changes in the issuer’s creditworthiness than are the prices of debt securities. Preferred stock also may be subject to optional or mandatory redemption provisions.

Real Estate Related Investments — The Fund may gain exposure to the real estate sector by investing in real estate-linked derivatives, REITs, and securities of corporate issuers in real estate-related industries. Adverse economic, business or political developments affecting real estate could have an effect on the value of the Fund’s investments. Investing in securities issued by real estate and real estate-related companies may subject the Fund to risks associated with the direct ownership of real estate, including the cyclical nature of real estate values, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses, demographic trends and variations in rental income, changes in zoning laws, casualty or condemnation losses, environmental risks, regulatory limitations on rents, changes in neighborhood values, changes in the appeal of properties to tenants and extended vacancies of properties, increases in interest rates, the financial condition of tenants, buyers and sellers, the quality of maintenance, insurance, and management services, and other real estate capital market influences. Changes in interest rates, debt leverage ratios, debt maturity schedules, and the availability of credit to real estate companies may also affect the value of the Fund’s investment in real estate securities. Real estate securities are dependent upon specialized management skills at the operating company level. Such securities also have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of properties. Real estate securities are subject to heavy cash flow dependency and defaults by borrowers. An economic downturn could have an adverse effect on the real estate markets and real estate companies. In addition, if a real estate company’s properties do not generate sufficient income to meet operating expenses, including debt service, ground lease payments, tenant improvements, third party leasing commissions and other capital expenditures, the income and ability of the real estate company to make payments of any interest and principal on its debt securities will be adversely affected. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. The financial results of major local employers also may have an impact on the cash flow and value of certain properties. In addition, certain real estate investments are relatively illiquid and, therefore, the ability of real estate companies to vary their portfolios promptly in response to changes in economic or other conditions is limited. A real estate company may also have joint venture investments in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

Small-Capitalization Companies Risk — Investing in the securities of small-capitalization companies involves greater risk and the possibility of greater price volatility, which at times can be rapid and unpredictable, than investing in larger capitalization and more established companies, since smaller companies may have limited operating history, product lines, and financial resources. The securities of these companies may lack sufficient market liquidity and they can be particularly sensitive to expected changes in overall economic conditions, interest rates, borrowing costs and earnings.

Trust Preferred Securities  — The Fund may invest in trust preferred securities. Trust preferred securities have the characteristics of both subordinated debt and preferred stock. Generally, trust preferred securities are issued by a trust that is wholly owned by a financial institution or other corporate entity, typically a bank holding company. The financial institution creates the trust and owns the trust’s common securities. The trust uses the sale proceeds of its common securities to purchase subordinated debt issued by the financial institution. The financial institution uses the proceeds from the subordinated debt sale to increase its capital while the trust receives periodic interest payments from the financial institution for holding the subordinated debt. The trust uses the funds received to make dividend payments to the holders of the trust preferred securities. The primary advantage of this structure is that the trust preferred securities are treated by the financial institution as debt securities for tax purposes and as equity for the calculation of capital requirements.

Trust preferred securities typically bear a market rate coupon comparable to interest rates available on debt of a similarly rated issuer. Typical characteristics include long-term maturities, early redemption by the issuer, periodic fixed or variable interest payments, and maturities at face value. Holders of trust preferred securities have limited voting rights to control the activities of the trust and no voting rights with respect to the financial institution. The market value of trust preferred securities may be more volatile than those of conventional debt securities. Trust preferred securities may be thinly traded and the Fund may not be able to dispose of them at a favorable price. Trust preferred securities may be issued in reliance on Rule 144A under the Securities Act and subject to restrictions on resale. There can be no assurance as to the liquidity of trust preferred securities and the ability of holders, such as the Fund, to sell their holdings. Please refer to “Illiquid and Restricted Securities” above for further discussion of regulatory considerations and constraints related to such securities. As the trust typically has no business operations other than to issue the trust preferred securities, the condition of the financial institution could have an impact on the Fund. If the financial institution defaults on interest payments to the trust, the trust will not be able to make dividend payments to holders of its securities, such as the Fund.  

Value Companies Risk — Value companies are subject to the risk that their intrinsic or full value may never be realized by the market, that a stock judged to be undervalued may be appropriately priced, or that their prices may go down. While the Fund’s investments in value stocks may limit its downside risk over time, the Fund may produce more modest gains than riskier stock funds as a trade-off for this potentially lower risk. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment. The Fund’s investments in value stocks may underperform growth or non-value stocks that have a broader investment style.

INVESTMENT RESTRICTIONS

Fundamental Investment Restrictions. The following discusses the investment policies of the Fund.

6 

Back to Table of Contents

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:

Under the Investment Company Act, the above limitations (except the limitation on borrowings) are based upon asset values at the time of the applicable transaction; accordingly, a subsequent change in asset values will not affect a transaction that was in compliance with the investment restrictions at the time such transaction was effected.

For purposes of the Fund’s policy relating to making loans set forth in (4) above, 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 the Fund’s policy relating to issuing senior securities set forth in (5) above, “senior securities” are defined as Fund obligations that have a priority over the Fund’s shares with respect to the payment of dividends or the distribution of Fund assets. The Investment Company Act prohibits the Fund from issuing any class of senior securities or selling any senior securities of which it is the issuer, except that the Fund is permitted to borrow from a bank so long as, immediately after such borrowings, there is an asset coverage of at least 300% for all borrowings of the Fund (not including borrowings for temporary purposes in an amount not exceeding 5% of the value of the Fund’s total assets). In the event that such asset coverage falls below this percentage, the Fund is required to reduce the amount of its borrowings within three days (not including Sundays and holidays) so that the asset coverage is restored to at least 300%. Consistent with guidance issued by the SEC and its staff, the requisite asset coverage may vary among different types of instruments. The policy in (5) above will be interpreted not to prevent collateral arrangements with respect to swaps, options, forward or futures contracts or other derivatives, or the posting of initial or variation margin.

For purposes of the Fund’s industry concentration policy set forth in (8) above, the Manager or the sub-advisor may analyze the characteristics of a particular issuer and instrument and may assign an industry classification consistent with those characteristics. The Manager or the sub-advisor may, but need not, consider industry classifications provided by third parties, and the classifications applied to Fund investments will be informed by applicable law.   A large economic or market sector shall not be construed as a particular industry or group of industries. The Manager currently considers securities issued by a foreign government (but not the  U.S. Government or its agencies or instrumentalities) to be an “industry” subject to the 25% limitation. Thus, not more than 25% of the Fund’s total assets will be invested in securities issued by any one foreign government or supranational organization. The Fund might invest in certain securities issued by companies in a particular industry whose obligations are guaranteed by a foreign government. The Manager could consider such a company to be within the particular industry and, therefore, the Fund will invest in the securities of such a company only if it can do so under its industry concentration policy.

Except for the investment restrictions listed above as fundamental or to the extent designated as such in the Prospectus, 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 or  the sub-advisor 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.

7  

Back to Table of Contents

These temporary investments can include: (i) obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities; (ii) commercial paper rated in the highest short-term category by a rating organization; (iii) domestic, Yankee and Eurodollar certificates of deposit or bankers’ acceptances of banks rated in the highest short-term category by a rating organization; (iv) any of the foregoing securities that mature in one year or less (generally known as “cash equivalents”); (v) other short-term corporate debt obligations; (vi) repurchase agreements; (vii) futures; or (viii) shares of money market funds, including funds advised by the Manager or the sub-advisor.

PORTFOLIO TURNOVER

Portfolio turnover is a measure of trading activity in a portfolio of securities, usually calculated over a period of one year. The rate is calculated by dividing the lesser amount of purchases or sales of securities by the average amount of securities held over the period. A portfolio turnover rate of 100% would indicate that the Fund sold and replaced the entire value of its securities holdings during the period. High portfolio turnover can increase the Fund’s transaction costs and generate additional capital gains or losses.

Portfolio turnover may vary significantly from year to year due to a variety of factors, including fluctuating volume of shareholder purchase and redemption orders, market conditions, investment strategy changes, and/or changes in the sub-advisor’s investment outlook.

DISCLOSURE OF PORTFOLIO HOLDINGS

The  Fund publicly discloses portfolio holdings information as follows:

Disclosure of Nonpublic Holdings
Occasionally, certain interested parties — including individual investors, institutional investors, market participants, third-party service providers, and others — may request portfolio holdings information that has not yet been publicly disclosed by the Fund. The Fund’s policy is to control the disclosure of nonpublic portfolio holdings information in an attempt to prevent parties from utilizing such information to engage in trading activity harmful to Fund shareholders. To this end, the Board has adopted a Holdings Policy. The purpose of the Holdings Policy is to define those interested parties who are authorized to receive nonpublic portfolio holdings information on a selective basis and to set forth conditions upon which such information may be provided. In general, nonpublic portfolio holdings may be disclosed on a selective basis only when it is determined that: (i) there is a legitimate business purpose for the information; (ii) recipients are subject to a duty of confidentiality, including a duty not to trade on the nonpublic information; and (iii) disclosure is in the best interests of Fund shareholders. The Holdings Policy does not restrict the Fund from disclosing that a particular security is not a holding of the Fund. The Holdings Policy is summarized below.

A variety of third-party service providers require access to Fund holdings to provide services to the Fund or to assist the Manager and the sub-advisor 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 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  Board  fulfills a legitimate business purpose, is in the best interest of Fund shareholders, and each Trustee is subject to a duty of confidentiality.

Back to Table of Contents

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

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 in the ordinary course of business. These third parties include: broker-dealers, the Exchange, Authorized Participants, market makers, and legal counsel. Broker-dealers utilized by the Fund in the process of purchasing and selling portfolio securities or providing market quotations receive limited nonpublic holdings information on a current basis with no lag. The Exchange may receive current holdings information with no lag through discussions with the Manager regarding the Fund’s compliance with the listing standards. Authorized Participants and market makers may receive current holdings information with no lag in connection with negotiations of Custom Baskets (as defined below). The Manager or sub-advisor may provide current holdings information with no lag to legal counsel when seeking advice regarding those holdings. 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.

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 nonpublic portfolio holdings information.  

Under the Holdings Policy, disclosure of nonpublic portfolio holdings information to parties other than those discussed above must be approved by the Trust’s Chief Compliance Officer, or in her absence, by a Vice President of the Trust.

In determining whether to approve a request for nonpublic portfolio holdings disclosure, the CCO shall consider the restrictions on selective disclosure imposed by applicable law, the type of requestor and its relationship to the Fund, the stated reason for the request, any historical pattern of requests from that same individual or entity, the style and strategy of the Fund for which holdings have been requested (e.g., passive versus active management), whether the Fund is managed by one or multiple investment managers, and any other factors she deems relevant. In her analysis, the CCO shall attempt to uncover any apparent conflict between the interests of the Fund on the one hand and those of the Manager or an affiliated person of the Fund on the other. Any potential conflicts that arise as a result of a request for portfolio holdings information shall be decided by the CCO in the best interests of the Fund’s shareholders. On a quarterly basis, the Manager will prepare a report for the Board outlining any instances of disclosures of nonpublic holdings during the period that did not comply with the Holdings Policy. The CCO generally determines whether a historical pattern of requests by the same individual or entity constitutes an “ongoing arrangement” and should be disclosed in the Fund’s SAI.

The Manager and the sub-advisor to the Fund may manage substantially similar portfolios for clients other than the Fund. Those other clients may receive and publicly disclose their portfolio holdings information prior to public disclosure by the Fund. The Holdings Policy is not intended to limit the Manager or the sub-advisor from making such disclosures to their clients.

LENDING OF PORTFOLIO SECURITIES

The  Fund may lend securities from its portfolio to brokers, dealers and other financial institutions needing to borrow securities to complete certain transactions. In connection with such loans, the Fund remains the beneficial owner of the loaned securities and continues to be entitled to payments in amounts approximately equal to the interest, dividends or other distributions payable on the loaned securities. The Fund also has the right to terminate a loan at any time. The  Fund does not have the right to vote on securities while they are on loan. However, it is the Fund’s policy to attempt to terminate loans in time to vote those proxies that the Fund determines are material to its interests. Loans of portfolio securities may not exceed 33¹/₃% of the value of the Fund’s total assets (including the value of all assets received as collateral for the loan). The Fund will receive collateral consisting of cash in the form of cash or cash equivalents, securities of the U.S. Government and its agencies and instrumentalities, approved bank letters of credit, or other forms of collateral that are permitted by the SEC for registered investment companies, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. If the collateral consists of cash, the Fund will reinvest the cash and may pay the borrower a pre-negotiated fee or “rebate” for the use of that cash collateral. Under the terms of the securities loan agreement between the

Fund and State Street, its securities lending agent, State Street indemnifies the Fund  for certain losses resulting from a borrower default. However, should the borrower of the securities fail financially,  the Fund may experience delays in recovering the loaned securities or exercising its rights in the collateral. In a loan transaction, the Fund will also bear the risk of any decline in value of securities acquired with cash collateral. The Fund seeks to minimize this risk by normally limiting the investment of cash collateral to registered money market funds, including money market funds advised by the Manager that invest in U.S. Government and agency securities.

For all funds that engage in securities lending, the Manager receives compensation for administrative and oversight functions with respect to securities lending, including oversight of the securities lending agent. The amount of such compensation depends on the income generated by the loan of the securities.

As of the date of this SAI, the Fund does not intend to engage in securities lending activities.

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.

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, 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 plan under 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

All but one member of the Board are Independent Trustees. Douglas A. Lindgren, an Independent Trustee, serves as Chair of the Board. The 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 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 standing 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 whether to approve the Fund’s management

agreement with the Manager and, as applicable, its investment advisory agreement(s) with its investment advisor(s), while specific matters related to oversight of the Fund’s independent auditors have been delegated by the Board to its Audit and Compliance Committee. 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 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 [XX]  series within the American Beacon Funds, [XX]  series within the American Beacon Institutional Funds Trust, and  [XX] series 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  [XX] series.

The Board holds five (5) regularly scheduled meetings each year. The Board may hold special meetings, as needed, either in person or by videoconference or telephone, to address matters arising between regular meetings. The Independent Trustees also conduct executive sessions without the presence of management personnel, including at least quarterly in a session at which no Trustees who are interested persons or management are present and may hold special meetings, as needed, either in person or by videoconference or 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, and shareholders may contact them directly, individually or collectively as a Board, at such address. Each Trustee serves for an indefinite term or until his or her removal, resignation, or retirement.*

For his service as Board Chair, Mr. Lindgren receives an additional annual retainer of $50,000. Although he attends several committee meetings at each quarterly Board meeting, he receives a single $2,500 fee each quarter for his attendance at the Audit Committee and Investment Committee meetings.

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”). 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. None of the current Trustees are Eligible Trustees.    

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, four individuals who retired from the Board and accrued retirement benefits for periods prior to September 12, 2008, have assumed Trustee Emeritus status. Three individuals and their spouses receive annual flight benefits of up to $40,000 combined, on a tax-grossed up basis, on American Airlines. One individual receives an annual retainer of $20,000 from the Trusts in lieu of flight benefits.

CODE OF ETHICS

The Manager, the Trust, and the sub-advisor each have adopted a Code of Ethics under Rule 17j-1 of the Investment Company Act. Each Code of Ethics significantly restricts the personal trading of all employees with access to non-public portfolio information. For example, each 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. Each Code of Ethics is on public file with, and may be obtained from, the SEC.

PROXY VOTING POLICIES

From time to time, the Fund may own a security whose issuer solicits a proxy vote on certain matters. The Board seeks to ensure that proxies are voted in the best interests of the Fund’s shareholders and has delegated proxy voting authority to the Manager. The Manager in turn has delegated proxy voting authority to  the sub-advisor with respect to the Fund’s assets under the sub-advisor’s management. The Trust has adopted a Proxy Policy that governs proxy voting by the Manager and sub-advisor, including procedures to address potential conflicts of interest between the Fund’s shareholders and the Manager, the  sub-advisor or their affiliates. The Board has approved the Manager’s proxy voting policies and procedures with respect to Fund assets under the Manager’s management. Please see Appendix A for a copy of the Proxy Policy. The sub-advisor’s proxy voting policy and procedures are summarized (or included in their entirety) in Appendix B. The Fund’s proxy voting record for the most recent year ended June 30 is available as of August 31 of each year without charge on the Funds’ website, on the SEC’s website at http://www.sec.gov or upon request by calling 1-800-967-9009. The proxy voting record can be found in Form N-PX on the SEC’s website.

CONTROL PERSONS AND 5% SHAREHOLDERS

A principal shareholder is any person who owns of record or beneficially 5% or more of the Fund’s outstanding shares. A control person is a shareholder that owns beneficially or through controlled companies more than 25% of the voting securities of a company or acknowledges the existence of control. Shareholders owning voting securities in excess of 25% may determine the outcome of any matter affecting and voted on by shareholders of the Fund. The actions of an entity or person that controls the Fund could have an effect on other shareholders. For instance, a control person may have effective voting control over the Fund or large redemptions by a control person could cause the Fund’s other shareholders to pay a higher pro rata portion of the Fund’s expenses.

As of the date of this SAI, the Manager is the sole shareholder of the Fund.

INVESTMENT ADVISORY AGREEMENT

The  Fund’s sub-advisor is listed below with information regarding its controlling persons or entities. According to the Investment Company Act, a person or entity with control with respect to an investment advisor has “the power to exercise a controlling influence over the management or policies of a company, unless such power is solely the result of an official position with such company.” Persons and entities affiliated with the sub-advisor may be considered affiliates of the Fund.

The Manager has entered into an Investment Advisory Agreement with The London Company pursuant to which the Manager has agreed to pay  The London Company an annualized sub-advisory fee that is calculated and accrued daily. Pursuant to the Investment Advisory Agreement,  The London Company has agreed to reimburse the Manager for a portion of Fund expenses incurred by the Manager.
