ADDITIONAL INFORMATION ABOUT INVESTMENT STRATEGIES AND RISKS

The investment objective and principal investment strategies and risks of the Fund 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.

Asset-Backed Securities — Asset-backed securities are securities issued by trusts and special purpose entities that are backed by pools of assets, such as automobile and credit-card receivables and home equity loans, which pass through the payments on the underlying obligations to the security holders (less servicing fees paid to the originator or fees for any credit enhancement). Typically, loans or accounts receivable paper are transferred from the originator to a specially created trust, which repackages the trust's interests as securities with a minimum denomination and a specific term. The securities are then privately placed or publicly offered. Examples include certificates for automobile receivables and so called plastic bonds, backed by credit card receivables. The Fund is permitted to invest in asset-backed securities, subject to the Fund's rating and quality requirements.

The value of an asset-backed security is affected by, among other things, changes in the market's perception of the asset backing the security, the creditworthiness of the servicing agent for the loan pool, the originator of the loans and the financial institution providing any credit enhancement. Payments of principal and interest passed through to holders of asset-backed securities are frequently supported by some form of credit enhancement, such as a letter of credit, surety bond, limited guarantee by another entity or by having a priority to certain of the borrower's other assets. The degree of credit enhancement varies, and generally applies to only a portion of the asset-backed security's par value. Value is also affected if any credit enhancement has been exhausted.

Cash Equivalents — Cash equivalents include certificates of deposit, time deposits, bearer deposit notes, bankers' acceptances, government obligations, commercial paper, short-term corporate debt securities and repurchase agreements.

Bankers' acceptances are short-term credit instruments designed to enable businesses to obtain funds to finance commercial transactions. Generally, an acceptance is a time draft drawn on a bank by an exporter or an importer to obtain a stated amount of funds to pay for specific merchandise. The draft is then "accepted" by a bank that, in effect, unconditionally guarantees to pay the face value of the instrument on its maturity date. The acceptance may then be held by the accepting bank as an earning asset or it may be sold in the secondary market at the going rate of discount for a specific maturity. Although maturities for acceptances can be as long as 270 days, most acceptances have maturities of six months or less.

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

Time deposits are non-negotiable deposits maintained at a banking institution for a specified period of time at a specified interest rate.

Common Stock — Common stock generally takes the form of shares in a corporation which represent an ownership interest. It ranks below preferred stock and debt securities in claims for dividends and for assets of the company in a liquidation or bankruptcy. The value of a company's common stock may fall as a result of factors directly relating to that company, such as decisions made by its management or decreased demand for the company's products or services. A stock's value may also decline because of factors affecting not just the company, but also companies in the same industry or sector. The price of a company's stock may also be affected by changes in financial markets that are relatively unrelated to the company, such as changes in interest rates, currency exchange rates or industry regulation. Companies that elect to pay dividends on their common stock generally only do so after they invest in their own business and make required payments to bondholders and on other debt and preferred stock. Therefore, the value of a company's common stock will usually be more volatile than its bonds, other debt and preferred stock. Common stock may be exchange-traded or over-the-counter ("OTC"). OTC stock may be less liquid than exchange-traded stock.

Convertible Securities — Convertible securities include corporate bonds, notes, 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. 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 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. 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. 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

Table of Contents

similar non-convertible securities of the same issuer. 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 actions (for example, 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 ("Voluntary Action"). Notwithstanding any percentage investment limitation listed under the "Investment Restrictions" section or any percentage investment limitation of the Investment Company Act of 1940, as amended (the "Investment Company Act" or "1940 Act") or rules thereunder, if the Fund has the opportunity to acquire a permitted security or instrument through a Voluntary Action, and the Fund will 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 offering, 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 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 guidance from the U.S. Securities and Exchange Commission (the "SEC") and other applicable regulatory bodies with respect to coverage of certain investments and trading practices. This guidance requires segregation (which may include earmarking) by the Fund of cash or liquid assets with its custodian or a designated sub-custodian to the extent the Fund's obligations with respect to these strategies are not otherwise "covered" through ownership of the underlying security or financial instrument or by offsetting portfolio positions.

For example, if the Fund enters into a currency forward contract to sell foreign currency on a future date, the Fund may cover its obligation to deliver the foreign currency by segregating cash or liquid assets having a value at least equal to the value of the deliverable currency. Alternatively, the Fund could cover its obligation by entering into an offsetting transaction to acquire, on or before the date such foreign currency must be delivered, an amount of foreign currency at least equal to the deliverable amount at a price at or below the sale price to be received by the Fund under the currency forward contract.

The Fund's approach to asset coverage may vary among different types of investments. For example, if the Fund's forward obligation on the transaction is only to make a cash payment equal to the amount, if any, by which the value of the Fund's position is less than that of its counterparty, the Fund will segregate cash or liquidate assets equal to that difference calculated on a daily marked-to-market basis (a "net amount"). Additionally, if the Fund is a protection seller in a credit default swap, the Fund, depending on how the credit default swap is settled, usually will segregate assets equal to the full notional value of the swap. If the Fund is protection buyer in a credit default swap, depending on how the credit default swap is settled, it usually will cover the total amount of required premium payments plus the prepayment penalty.

Inasmuch as the Fund covers its obligations under these transactions as described above, American Beacon Advisors, Inc. (the "Manager") and the Fund believe such obligations do not constitute senior securities. Earmarking or otherwise segregating a large percentage of the Fund's assets could impede the sub-advisor's ability to manage the Fund's portfolio.

Creditor Liability and Participation on Creditors Committees — When the Fund holds bonds or other similar fixed income securities of an issuer, the Fund becomes a creditor of the issuer. If the Fund is a creditor of an issuer it may be subject to challenges related to the securities that it holds, either in connection with the bankruptcy of the issuer or in connection with another action brought by other creditors of the issuer, shareholders of the issuer or the issuer itself. The Fund may from time to time participate on committees formed by creditors to negotiate with the management of financially troubled issuers of securities held by the Fund. Such participation may subject the Fund to expenses such as legal fees and may make the Fund an "insider" of the issuer for purposes of the federal securities laws, and therefore may restrict such Fund's ability to trade in or acquire additional positions in a particular security when it might otherwise desire to do so. Participation on such committees also may expose the Fund to potential liabilities under the federal bankruptcy laws or other laws governing the rights of creditors and debtors.

Cyber-Security Risk — The Fund, and its service providers, may be prone to operational and information security risks resulting from cyber-attacks. Cyber-attacks include, among other behaviors, stealing or corrupting data maintained online or digitally, denial of service attacks on websites, the unauthorized release of confidential information or various other forms of cyber security breaches. Cyber-attacks affecting the Fund or its sub-advisor(s), custodian, 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, impact the Fund's ability to calculate its NAV, cause the release of private shareholder information or confidential business information, impede trading, subject the Fund to regulatory fines or financial losses and/or cause reputational damage. The Fund may also incur additional costs for cyber security risk management purposes. While the Fund's service providers have established business continuity plans in the event of, and risk management systems to prevent, such cyber-attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cyber security plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund or its shareholders. Similar types of cyber security risks are also present for issues or securities in which the Fund may invest, which could result in material adverse consequences for such issuers and may cause the Fund's investment in such companies to lose value.

Depositary Receipts — American Depositary Receipts (ADRs) — ADRs are depositary receipts for foreign issuers in registered form traded in U.S. securities markets. Depositary receipts may not be denominated in the same currency as the securities into which they may be converted. Investing in depositary receipts entails substantially the same risks as direct investment in foreign securities. There is generally less publicly available information about foreign companies and there may be less governmental regulation and supervision of foreign stock exchanges, brokers and listed companies. In addition, such companies may use different accounting and financial standards. In addition, the Fund may invest in unsponsored depositary receipts, the issuers of which are not obligated to disclose material information about the underlying securities to investors in the United States. Ownership of unsponsored depositary receipts may not entitle the Fund to the same benefits and rights as ownership of a sponsored depositary receipt or the underlying security. Please see "Foreign Securities" below for a description of the risks associated with investments in foreign securities.

Derivatives — Generally a derivative is a financial arrangement, the value of which is based on, or "derived" from, a traditional security, asset, currency, or market index. Some derivatives are in many respects like any other investment, although they may be more volatile or less liquid than more traditional debt securities. There are, in fact, many different types of derivatives and many different ways to use them. The value of certain derivative securities is linked to other equity securities (such as depositary receipts), currencies, interest rates, indices or other financial indicators (reference assets).

The Fund may invest in various types of derivatives, including among others, options (including non-deliverable options), futures, forward currency and other forwards (including non-deliverable forwards), forwards for currency hedges, warrants, structured products (including credit-linked and structured notes), interest rate caps, floors, collars, reverse collars, and credit default swaps. The enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") resulted in historic and comprehensive reform relating to derivatives, including the manner in which they are entered into, reported, recorded, executed, and settled or cleared. Pursuant to the Dodd-Frank Act the SEC and the U.S. Commodity Futures Trading Commission ("CFTC") have promulgated a broad range of new regulations with respect to security-based swaps (e.g., derivatives based on a single security or narrow-based securities index), which are regulated by the SEC), and other swaps, which are regulated by the CFTC and the markets in which these instruments trade.

Until recently, advisers of registered investment companies, like the Fund, that trade commodity interests (such as futures contracts, options on futures contracts, non-deliverable forwards and swaps), have been excluded from regulation as commodity pool operators ("CPOs") pursuant to CFTC Regulation 4.5. In 2012, the CFTC amended Regulation 4.5 to dramatically narrow this exclusion. Under the amended Regulation 4.5 exclusion, in order to rely on the exclusion the Fund's commodity interests – other than those used for bona fide hedging purposes (as defined by the CFTC) – must be limited such that the aggregate initial margin and premiums required to establish the positions (after taking into account unrealized profits and unrealized losses on any such positions and excluding the amount by which options that are "in-the-money" at the time of purchase) does not exceed 5% of the Fund's NAV, or alternatively, the aggregate net notional value of the positions, determined at the time the most recent position was established, does not exceed 100% of the Fund's NAV (after taking into account unrealized profits and unrealized losses on any such positions). Further, to qualify for the exclusion in amended Regulation 4.5, the Fund must satisfy a marketing test, which requires, among other things, that the Fund not hold itself out as a vehicle for trading commodity interests. The Fund's ability to use these instruments also may be limited by tax considerations. See the section entitled "Tax Information."

The Manager has filed a notice claiming the CFTC Regulation 4.5 exclusion from CPO registration.

Derivatives may involve significant risk. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. Not all derivative transactions require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty.

Derivatives may be illiquid and may be more volatile than other types of investments. The Fund may buy and sell derivatives that are neither centrally cleared nor traded on an exchange. Such derivatives may be subject to heightened liquidity and valuation risk.

Transactions in derivatives may expose the Fund to an obligation to another party and, as a result, the Fund may need to "cover" the obligation or segregate liquid assets in compliance with SEC guidelines, as discussed above under "Cover and Asset Segregation."

Delayed Funding Loans and Revolving Credit Facilities  — The Fund may enter into, or acquire participations in, delayed funding loans and revolving credit facilities. Delayed funding loans and revolving credit facilities are borrowing arrangements in which the lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. A revolving credit facility differs from a delayed funding loan in that as the borrower repays the loan, an amount equal to the repayment may be borrowed again during the term of the revolving credit facility. Delayed funding loans and revolving credit facilities usually provide for floating or variable rates of interest. These commitments may have the effect of requiring the Fund to increase its investment in a company at a time when it might not otherwise decide to do so (including at a time when the company's financial condition makes it unlikely that such amounts will be repaid). To the extent that the Fund is committed to advance additional funds, it will at all times segregate or "earmark" assets, determined to be liquid in accordance with procedures established by the Trust's Board of Trustees (the "Board"), in an amount sufficient to meet such commitments.

The Fund may invest in delayed funding loans and revolving credit facilities with credit quality comparable to that of issuers of its securities investments. Delayed funding loans and revolving credit facilities may be subject to restrictions on transfer, and only limited opportunities may exist to resell such instruments. As a result, the Fund may be unable to sell such investments at an opportune time or may have to resell them at less than fair market value.

Distressed Investment Risk — The Fund may invest in distressed investments, which are issued by companies that are, or might be, involved in reorganizations or financial restructurings, either out of court or in bankruptcy.  These investments may present a substantial risk of default or may be in default at the time of investment.  The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal or interest on its portfolio holdings.  In any reorganization or liquidation proceeding relating to an investment, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment.  Among the risks inherent in investments in a troubled issuer is that it frequently may be difficult to obtain information as to the true financial condition of the issuer.

Equity Securities — In connection with its purchase or holding of interests in senior floating rate loans ("Floating Rate Loans"), in the event of an in court or out of court restructuring, the Fund may acquire (and subsequently sell) equity securities or exercise warrants that it receives.

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 Securities — The Fund may invest in securities of foreign issuers. 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 securities 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 include the possibility of adverse political and economic developments (including political or social instability, nationalization, expropriation, or confiscatory taxation); the potentially adverse effects of unavailability of public information regarding 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 tracking; and possibly limited access to the courts to enforce the Fund's rights as an investor.

Investing in foreign currency denominated securities involves the special risks associated with investing in non-U.S. issuers, as described in the preceding paragraph, and the additional risks of (1) adverse changes in foreign exchange rates and (2) adverse changes in 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.

Commissions on foreign securities exchanges are often at fixed rates and are generally higher than negotiated commissions on U.S. exchanges, although the sub-advisor endeavors to achieve the most favorable net results on portfolio transactions.

Foreign securities may trade with less frequency and in less volume than domestic securities and therefore may exhibit greater price volatility. 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.

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. 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.

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. Individual foreign economies may 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.

Futures Contracts — Futures contracts, including interest rate and U.S. Treasury futures contracts, obligate a purchaser to take delivery of a specific amount of an obligation underlying the futures contract at a specified time in the future for a specified price. Likewise, the seller incurs an obligation to deliver the specified amount of the underlying obligation against receipt of the specified price. Futures are traded on both U.S. and foreign commodities exchanges. Futures contracts will be traded for the same purposes as entering into forward contracts. The purchase of futures can serve as a long hedge, and the sale of futures can serve as a short hedge.

No price is paid upon entering into a futures contract. Instead, at the inception of a futures contract the Fund is required to deposit "initial margin" consisting of cash or U.S. Government Securities in an amount set by the exchange on which the contract is traded and varying based on the volatility of the underlying asset. Margin must also be deposited when writing a call or put option on a futures contract, in accordance with applicable exchange rules. Unlike margin in securities transactions, initial margin on futures contracts does not represent a borrowing, but rather is in the nature of a performance bond or good-faith deposit that is returned to the Fund at the termination of the transaction if all contractual obligations have been satisfied. Under certain circumstances, such as periods of high volatility, the Fund may be required by a futures exchange to increase the level of its initial margin payment, and initial margin requirements might be increased generally in the future by regulatory action.

Subsequent "variation margin" payments are made to and from the futures broker daily as the value of the futures position varies, a process known as "marking-to-market." Variation margin does not involve borrowing, but rather represents a daily settlement of the Fund's obligations to or from a futures broker. When the Fund purchases or sells a futures contract, it is subject to daily variation margin calls that could be substantial in the event of adverse price movements. If the Fund has insufficient cash to meet daily variation margin requirements, it might need to sell securities at a time when such sales are disadvantageous.

Purchasers and sellers of futures contracts can enter into offsetting closing transactions, by selling or purchasing, respectively, an instrument identical to the instrument purchased or sold. Positions in futures contracts may be closed only on a futures exchange or board of trade that provides a secondary market. The Fund intends to enter into futures contracts only on exchanges or boards of trade where there appears to be a liquid secondary market. However, there can be no assurance that such a market will exist for a particular contract at a particular time. In such event, it may not be possible to close a futures contract.

Although futures contracts by their terms call for the actual delivery or acquisition of securities or currency, in most cases the contractual obligation is fulfilled before the date of the contract without having to make or take delivery of the securities or currency. The offsetting of a contractual obligation is accomplished by buying (or selling, as appropriate) on a commodities exchange an identical futures contract calling for delivery in the same month. Such a transaction, which is effected through a member of an exchange, cancels the obligation to make or take delivery of the securities or currency. Since all transactions in the futures market are made, offset or fulfilled through a clearinghouse associated with the exchange on which the contracts are traded, the Fund will incur brokerage fees when it purchases or sells futures contracts.

Under certain circumstances, futures exchanges may establish daily limits on the amount that the price of a futures contract can vary from the previous day's settlement price; once that limit is reached, no trades may be made that day at a price beyond the limit. Daily price limits do not limit potential

Table of Contents

losses because prices could move to the daily limit for several consecutive days with little or no trading, thereby preventing liquidation of unfavorable positions.

If the Fund were unable to liquidate a futures contract due to the absence of a liquid secondary market or the imposition of price limits, it could incur substantial losses. The Fund would continue to be subject to market risk with respect to the position. In addition, the Fund would continue to be required to make daily variation margin payments and might be required to maintain the position being hedged by the futures contract or option thereon or to maintain cash or securities in a segregated account.

The ordinary spreads between prices in the cash and futures market, due to differences in the nature of those markets, are subject to distortions. First, all participants in the futures market are subject to initial deposit and variation margin requirements. Rather than meeting additional variation margin deposit requirements, investors may close futures contracts through offsetting transactions that could distort the normal relationship between the cash and futures markets. Second, the liquidity of the futures market depends on participants entering into offsetting transactions rather than making or taking delivery. To the extent participants decide to make or take delivery, liquidity in the futures market could be reduced, thus producing distortion. Third, from the point of view of speculators, the margin deposit requirements in the futures market are less onerous than margin requirements in the securities market. Therefore, increased participation by speculators in the futures market may cause temporary price distortions. Due to the possibility of distortion, a correct forecast of securities price or currency exchange rate trends by the sub-advisor may still not result in a successful transaction.

In addition, futures contracts entail risks. Although the use of such contracts may benefit the Fund, if investment judgment about the general direction of, for example, an index is incorrect, the Fund's overall performance would be worse than if it had not entered into any such contract. In addition, there are differences between the securities and futures markets that could result in an imperfect correlation between the markets, causing a given transaction not to achieve its objectives.

Illiquid and Restricted Securities — The Fund may invest in illiquid securities. Generally, an illiquid asset is an asset that cannot be disposed of in the ordinary course of business within seven days at approximately the price at which it has been valued. Historically, illiquid securities have included securities that have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), securities that are otherwise not readily marketable, and repurchase agreements having a remaining maturity of longer than seven calendar days. Securities that have not been registered under the Securities Act are referred to as private placements or restricted securities and are purchased directly from the issuer or in the secondary market. These securities may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. A large institutional market exists for certain securities that are not registered under the Securities Act, including repurchase agreements, commercial paper, foreign securities, municipal securities and corporate bonds and notes. Institutional investors depend on an efficient institutional market in which the unregistered security can be readily resold or on an issuer's ability to honor a demand for repayment.

Limitations on resale may have an adverse effect on the marketability of portfolio securities, and the Fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven calendar days. In addition, the Fund may get only limited information about an issuer, so it may be less able to predict a loss. The Fund also might have to register such restricted securities in order to dispose of them resulting in additional expense and delay. Adverse market conditions could impede such a public offering of securities.

In recognition of the increased size and liquidity of the institutional market for unregistered securities and the importance of institutional investors in the formation of capital, the SEC adopted Rule 144A under the Securities Act. Rule 144A is designed to facilitate efficient trading among institutional investors by permitting the sale of certain unregistered securities to qualified institutional buyers. To the extent privately placed securities held by the Fund qualify under Rule 144A and an institutional market develops for those securities, the Fund likely will be able to dispose of the securities without registering them under the Securities Act. To the extent that institutional buyers become, for a time, uninterested in purchasing these securities, investing in Rule 144A securities could increase the level of the Fund's illiquidity. The Manager or a sub-advisor, as applicable, acting under guidelines established by the Trust's Board of Trustees ("Board"), may determine that certain securities qualified for trading under Rule 144A are liquid. Regulation S under the Securities Act permits the sale abroad of securities that are not registered for sale in the United States and includes a provision for U.S. investors, such as the Fund, to purchase such unregistered securities if certain conditions are met. 

Securities sold in private placement offerings made in reliance on the "private placement" exemption from registration afforded by Section 4(a)(2) of the Securities Act and resold to qualified institutional buyers under Rule 144A under the Securities Act ("Section 4(a)(2) securities") are restricted as to disposition under the federal securities laws, and generally are sold to institutional investors, such as the Fund that agree they are purchasing the securities for investment and not with an intention to distribute to the public. Any resale by the purchaser must be pursuant to an exempt transaction and may be accomplished in accordance with Rule 144A. Section 4(a)(2) securities normally are resold to other institutional investors through or with the assistance of the issuer or dealers that make a market in the Section 4(a)(2) securities, thus providing liquidity.

The Manager and the sub-advisor will carefully monitor the Fund's investments in Section 4(a)(2) securities offered and sold under Rule 144A, focusing on such important factors, among others, as valuation, liquidity, and availability of information. Investments in Section 4(a)(2) securities could have the effect of reducing the Fund's liquidity to the extent that qualified institutional buyers no longer wish to purchase these restricted securities.

Indebtedness, Loan Participations and Assignments — Floating rate securities, including loans, provide for automatic adjustment of the interest rate at fixed intervals (e.g., daily, weekly, monthly, or semi-annually) or automatic adjustment of the interest rate whenever a specified interest rate or index changes. The interest rate on floating rate securities ordinarily is determined by reference to LIBOR (London Interbank Offered Rate), a particular bank's prime rate, the 90-day U.S. Treasury Bill rate, the rate of return on commercial paper or bank CDs, an index of short-term tax-exempt rates or some other objective measure.

Loan interests are a form of direct debt instrument in which the Fund may invest by taking an assignment of all or a portion of an interest in a loan previously held by another institution or by acquiring a participation in an interest in a loan that continues to be held by another institution. The Fund may invest in secured and unsecured loans. Many banks have been weakened by the recent financial crisis, and it may be difficult for the Fund to

Table of Contents

obtain an accurate picture of a lending bank's financial condition. Loans are subject to the same risks as other direct debt instruments discussed above and carry additional risks described in this section.

Assignments . When the Fund purchases a loan by assignment, the Fund typically succeeds to the rights of the assigning lender under the loan agreement and becomes a lender under the loan agreement. Subject to the terms of the loan agreement, the Fund typically succeeds to all the rights and obligations under the loan agreement of the assigning lender. However, assignments may be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender.

Participation Interests . The Fund's rights under a participation interest with respect to a particular loan may be more limited than the rights of original lenders or of investors who acquire an assignment of that loan. In purchasing participation interests, the Fund will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the participation interest (the "participating lender") and only when the participating lender receives the payments from the borrower.

In a participation interest, the Fund will usually have a contractual relationship only with the selling institution and not the underlying borrower. The Fund normally will have to rely on the participating lender to demand and receive payments in respect of the loans, and to pay those amounts on to the Fund; thus, the Fund will be subject to the risk that the lender may be unwilling or unable to do so. In such a case, the Fund would not likely have any rights against the borrower directly. In addition, the Fund generally will have no right to object to certain changes to the loan agreement agreed to by the participating lender.

In buying a participation interest, the Fund might not directly benefit from the collateral supporting the related loan and may be subject to any rights of set off the borrower has against the selling institution. In the event of bankruptcy or insolvency of the borrower, the obligation of the borrower to repay the loan may be subject to certain defenses that can be asserted by the borrower as a result of any improper conduct of the participating lender. As a result, the Fund may be subject to delays, expenses and risks that are greater than those that exist when the Fund is an original lender or assignee.

The Fund's ability to receive payments in connection with loans depends on the financial condition of the borrower. The Manager or the sub-advisor will not rely solely on another lending institution's credit analysis of the borrower, but will perform its own investment analysis of the borrower. The Manager's or the sub-advisor's analysis may include consideration of the borrower's financial strength, managerial experience, debt coverage, additional borrowing requirements or debt maturity schedules, changing financial conditions, and responsiveness to changes in business conditions and interest rates. Indebtedness of borrowers whose creditworthiness is poor involves substantially greater risks and may be highly speculative. Borrowers that are in bankruptcy or restructuring may never pay off their indebtedness, or may pay only a small fraction of the amount owed. In connection with the restructuring of a loan or other direct debt instrument outside of bankruptcy court in a negotiated work-out or in the context of bankruptcy proceedings, equity securities or junior debt securities may be received in exchange for all or a portion of an interest in the security.

In buying a participation interest, the Fund assumes the credit risk of both the borrower and the participating lender. If the participating lender fails to perform its obligations under the participation agreement, the Fund might incur costs and delays in realizing payment and suffer a loss of principal and/or interest. If a participating lender becomes insolvent, the Fund may be treated as a general creditor of that lender. As a general creditor, the Fund may not benefit from a right of set off that the lender has against the borrower. The Fund will acquire a participation interest only if the Manager or the sub-advisor determines that the participating lender or other intermediary participant selling the participation interest is creditworthy.

Loan interests may not be rated by independent rating agencies and therefore, investments in a particular loan participation may depend almost exclusively on the credit analysis of the borrower performed by the Manager or the sub-advisor.

Loans are typically administered by a bank, insurance company, finance company or other financial institution (the "agent") for a lending syndicate of financial institutions. In a typical loan, the agent administers the terms of the loan agreement and is responsible for the collection of principal and interest and fee payments from the borrower and the apportionment of these payments to all lenders that are parties to the loan agreement. In addition, an institution (which may be the agent) may hold collateral on behalf of the lenders. Typically, under loan agreements, the agent is given broad authority in monitoring the borrower's performance and is obligated to use the same care it would use in the management of its own property. In asserting rights against a borrower, the Fund normally will be dependent on the willingness of the lead bank to assert these rights, or upon a vote of all the lenders to authorize the action. If an agent becomes insolvent, or has a receiver, conservator, or similar official appointed for it by the appropriate regulatory authority, or becomes a debtor in a bankruptcy proceeding, the agent's appointment may be terminated and a successor agent would be appointed. If an appropriate regulator or court determines that assets held by the agent for the benefit of purchasers of loans are subject to the claims of the agent's general or secured creditors, the Fund might incur certain costs and delays in realizing payment on a loan or suffer a loss of principal and/or interest. The Fund may be subject to similar risks when it buys a participation interest or an assignment from an intermediary.

Although most of the loans in which the Fund invests are secured, there is no assurance that the collateral can be promptly liquidated, or that its liquidation value will be equal to the value of the debt. In most loan agreements there is no formal requirement to pledge additional collateral if the value of the initial collateral declines. As a result, a loan may not always be fully collateralized and can decline significantly in value. If a borrower becomes insolvent, access to collateral may be limited by bankruptcy and other laws. Borrowers that are in bankruptcy may pay only a small portion of the amount owed, if they are able to pay at all. If a secured loan is foreclosed, the Fund will likely be required to bear the costs and liabilities associated with owning and disposing of the collateral. There is also a possibility that the Fund will become the owner of its pro rata share of the collateral which may carry additional risks and liabilities. In addition, under legal theories of lender liability, the Fund potentially might be held liable as a co-lender. In the event of a borrower's bankruptcy or insolvency, the borrower's obligation to repay the loan may be subject to certain defenses that the borrower can assert as a result of improper conduct by the Agent. Some loans are unsecured. If the borrower defaults on an unsecured loan, the Fund will be a general creditor and will not have rights to any specific assets of the borrower.

Loans may be subject to legal or contractual restrictions on resale. Loans are not currently listed on any securities exchange or automatic quotation system. As a result, there may not be a recognized, liquid public market for loan interests.

Table of Contents

Because many loans are repaid early, the actual maturity of loans is typically shorter than their stated final maturity calculated solely on the basis of the stated life and payment schedule. The degree to which borrowers prepay loans, whether as a contractual requirement or at their election, may be affected by general business conditions, market interest rates, the borrower's financial condition and competitive conditions among lenders. Such prepayments may require the Fund to replace an investment with a lower yielding security which may have an adverse affect on the Fund's share price. Prepayments cannot be predicted with accuracy. Floating Rate Loans can be less sensitive to prepayment risk, but the Fund's NAV may still fluctuate in response to interest rate changes because variable interest rates may reset only periodically and may not rise or decline as much as interest rates in general.

A borrower must comply with various restrictive covenants in a loan agreement such as restrictions on dividend payments and limits on total debt. The loan agreement may also contain a covenant requiring the borrower to prepay the loan with any free cash flow. A breach of a covenant is normally an event of default, which provides the agent or the lenders the right to call the outstanding loan.

Purchasers and sellers of loans may pay certain fees, such as an assignment fee. In addition, the Fund incurs expenses associated with researching and analyzing potential loan investments, including legal fees. Available Information. Loans normally are not registered with the SEC or any state securities commission or listed on any securities exchange. As a result, the amount of public information available about a specific loan historically has been less extensive than if the loan were registered or exchange traded. They may also not be considered "securities," and purchasers, such as the Fund, therefore may not be entitled to rely on the strong anti-fraud protections of the federal securities laws.

Inflation Risk  — Inflation risk results from the variation in the value of cash flows from a security due to inflation, as measured in terms of purchasing power. For example, if the Fund purchases a 5-year bond in which it can realize a coupon rate of five percent (5%), but the rate of inflation is six percent (6%), then the purchasing power of the cash flow has declined. Fixed income securities, other than inflation-linked bonds, adjustable bonds and floating rate bonds, generally expose the Fund to inflation risk because the interest rate the issuer promises to make is fixed for the life of the security. To the extent that interest rates reflect the expected inflation rate, floating rate bonds have a lower level of inflation risk.

Interest Rates and Portfolio Maturity — Interest rates on loans in which the Fund invests adjust periodically. The interest rates are adjusted based on a base rate plus a premium or spread over the base rate. The base rate usually is the London Inter-Bank Offered Rate ("LIBOR"), the federal funds rate, the prime rate, or other base lending rates used by commercial lenders. LIBOR usually is an average of the interest rates quoted by several designated banks as the rates at which they pay interest to major depositors in the London interbank market on U.S. dollar-denominated deposits. The Advisor believe that changes in short-term LIBOR rates are closely related to changes in the Federal Reserve federal funds rate, although the two are not technically linked. The prime rate quoted by a major U.S. bank is generally the interest rate at which that bank is willing to lend U.S. dollars to its most creditworthy borrowers, although it may not be the bank's lowest available rate.

The Floating Rate Loans in which the Fund invests typically have multiple reset periods during the year with each reset period applicable to a designated portion of the loan. The Fund may find it possible and appropriate to use interest rate swaps and other investment practices to shorten the effective interest rate adjustment period of loans. If the Fund does so, it will consider the shortened period to be the adjustment period of the loan. As short-term interest rates rise, interest payable to the Fund should increase. As short-term interest rates decline, interest payable to the Fund should decrease. The amount of time that will pass before the Fund experiences the effects of changing short-term interest rates will depend on the dollar-weighted average time until the next interest rate adjustment on the Fund's portfolio of loans.

Loans usually have mandatory and optional prepayment provisions. Because of prepayments, the actual remaining maturity of a loan may be considerably less than its stated maturity. If a loan is prepaid, the Fund will have to reinvest the proceeds in other loans or securities, which may have a lower fixed spread over its base rate. In such a case, the amount of interest paid to the Fund would likely decrease.

In the event of a change in the benchmark interest rate on a loan, the rate payable to lenders under the loan will, in turn, change at the next scheduled reset date. If the benchmark rate goes up, the Fund as lender would earn interest at a higher rate, but only on and after the reset date. If the benchmark rate goes down, the Fund as lender would earn interest at a lower rate, but only on and after the reset date.

During normal market conditions, changes in market interest rates will affect the Fund in certain ways. The principal effect will be that the yield on the Fund's shares will tend to rise or fall as market interest rates rise and fall. This is because almost all of the assets in which the Fund invests pay interest at rates which float in response to changes in market rates. However, because the interest rates on the Fund's assets reset over time, there will be an imperfect correlation between changes in market rates and changes to rates on the portfolio as a whole. This means that changes to the rate of interest paid on the portfolio as a whole, will tend to lag behind changes in market rates.

Market interest rate changes may also cause the Fund's NAV to experience volatility. This is because the value of a loan asset in the Fund is partially a function of whether it is paying what the market perceives to be a market rate of interest for the particular loan given its individual credit and other characteristics. If market interest rates change, a loan's value could be affected to the extent the interest rate paid on that loan does not reset at the same time. The rates of interest paid on the loans in which the Fund invests have a weighted average reset period that typically is less than 90 days. Therefore, the impact of the lag between a change in market interest rates and the change in the overall rate on the portfolio is expected to be minimal.

Finally, to the extent that changes in market rates of interest are reflected, not in a change to a base rate such as LIBOR, but in a change in the spread over the base rate which is payable on loans of the type and quality in which the Fund invests, the Fund's NAV could be adversely affected. Again, this is because the value of a loan asset in the Fund is partially a function of whether it is paying what the market perceives to be a market rate of interest for the particular loan given its individual credit and other characteristics. However, unlike changes in market rates of interest for which there is only a temporary lag before the portfolio reflects those changes, changes in a loan's value based on changes in the market spread on loans in the Fund's portfolio may be of longer duration.

Interfund Lending — Pursuant to an order issued by the SEC, each series of the Trust (each an "American Beacon Fund", and together, the "American Beacon Funds" or "Funds") may participate in a credit facility whereby each American Beacon Fund, under certain conditions, is permitted

Table of Contents

to lend money directly to and borrow directly from other American Beacon Funds 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 areas 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 certain funds have insufficient cash on hand to satisfy such redemptions or when sales of securities do not settle as expected, resulting in a cash shortfall for a fund. When the funds liquidate portfolio securities to meet redemption requests, they often do not receive payment in settlement for up to three days (or longer for certain foreign transactions). However, redemption requests normally are satisfied immediately. 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 lines of credit or other borrowing arrangements with banks.

Investment Grade Securities — Investment grade securities that the Fund may purchase, either as part of its principal investment strategy or to implement its temporary defensive policy, include securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities, as well as securities rated in one of the four highest rating categories by at least two rating organizations rating that security (such as Standard & Poor's Ratings Services, Fitch, Inc. or Moody's Investors Service, Inc.) or rated in one of the four highest rating categories by one rating organization if it is the only organization rating that security. The Fund, at the discretion of the Manager or the applicable sub-advisor, may retain a security that has been downgraded below the initial investment criteria.

Lender Liability and Equitable Subordination Risks  — In recent years, a number of judicial decisions in the United States have upheld the right of borrowers to sue lenders or bondholders on the basis of various evolving legal theories (commonly referred to as "lender liability"). Generally, lender liability is founded upon the premise that an institutional lender or bondholder has violated a duty (whether implied or contractual) of good faith and fair dealing owed to the borrower or issuer or has assumed a degree of control over the borrower or issuer resulting in the creation of a fiduciary duty owed to the borrower or issuer or its other creditors or stockholders.

Leveraging Risk  — Borrowing transactions, reverse repurchase agreements, certain derivatives transactions, securities lending transactions and other investment transactions such as when-issued, delayed-delivery, or forward commitment transactions may create investment leverage. When the Fund engages in transactions that have a leveraging effect on the Fund's investment, the value of the Fund will be potentially more volatile and all other risks will tend to be compounded. This is because leverage generally creates investment risk with respect to a larger base of assets than the Fund would otherwise have and so magnifies the effect of any increase or decrease in the value of the Fund's underlying assets. The use of leverage is considered to be a speculative investment practice and may result in losses to the Fund. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The use of leverage may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy repayment, interest payment, or margin obligations or to meet asset segregation or coverage requirements.

Market Events — Turbulence in the economic, political and financial system has historically resulted, and may continue to result, in an unusually high degree of volatility in the capital markets. Both domestic and foreign capital markets have been experiencing increased volatility and turmoil, with issuers that have exposure to the real estate, mortgage and credit markets particularly affected, and it is uncertain whether or for how long these conditions could continue.

Reduced liquidity in equity, credit and fixed-income markets may adversely affect many issuers worldwide. This reduced liquidity may result in less money being available to purchase raw materials, goods and services from emerging markets, which may, in turn, bring down the prices of these economic staples. It may also result in small or emerging market issuers having more difficulty obtaining financing, which may, in turn, cause a decline in their security prices. These events and possible continued market turbulence may have an adverse effect on the Fund.

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 larger, capitalization companies. 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 — The Fund at times may invest in shares of other investment companies and exchange-traded products, including open-end funds, closed-end funds, business development companies, and exchange-traded funds ("ETFs"). The Fund may invest in investment company securities advised by the Manager or a sub-advisor to the Fund. 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 are reflected as Acquired Fund Fees and Expenses and are included in the Fees and Expenses Table for the Fund in its Prospectus, if applicable. Investment in other investment companies may involve the payment of substantial premiums above the value of such issuer's portfolio securities.

The Fund can invest free cash balances in registered open-end investment companies regulated as money market funds under the Investment Company Act, to provide liquidity or for defensive purposes. The Fund would invest in money market funds rather than purchasing individual short-term investments. If the Fund invests in money market funds shareholders will bear their proportionate share of the expenses, including for example, advisory and administrative fees, of the money market funds in which the Fund invests, including such fees charged by the Manager to any applicable money market funds advised by the Manager.

In July 2014, the SEC adopted amendments to Rule 2a-7 under the Investment Company Act, as amended, that will affect the manner in which money market funds are structured and operated. Money market funds must comply with the rule amendments in various stages over the next two years. The precise impact such amendments will have on a money market fund's structure and operations and on the money market fund industry has not yet been determined, but any related changes may negatively affect a money market fund's expenses, liquidity, yield and return potential.

Table of Contents

The Fund may purchase shares of ETFs. ETFs trade like a common stock and passive ETFs usually represent a fixed portfolio of securities designed to track the performance and dividend yield of a particular domestic or foreign market index. Typically, the Fund would purchase passive ETF shares to obtain exposure to all or a portion of the stock or bond market. As a shareholder of an ETF, the Fund would be subject to its ratable share of the ETF's expenses, including its advisory and administration expenses.

An investment in an ETF generally presents the same primary risks as an investment in a conventional mutual fund (i.e., one that is not exchange traded) that has the same investment objective, strategies, and policies. The price of an ETF can fluctuate within a wide range, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. In addition, ETFs are subject to the following risks that do not apply to conventional funds: (1) the market price of the ETF's shares may trade at a discount or premium to their net asset value; (2) an active trading market for an ETF's shares may not develop or be maintained; or (3) trading of an ETF's shares may be halted if the listing exchange's officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide "circuit breakers" (which are tied to large decreases in stock prices) halts stock trading generally. ETFs have expenses associated with their operation, typically including advisory fees.

Pay-in-Kind Securities  —  Pay-in-kind securities are debt securities that do not make regular cash interest payments. Pay-in-kind securities pay interest through the issuance of additional securities. Because these securities do not pay current cash income, their price can be volatile when interest rates fluctuate. Federal income tax law requires the holders of pay-in-kind securities to include in income each year the portion of the original issue discount (or deemed discount) and other non-cash income on such securities accrued during that year. In order to qualify for treatment as a "regulated investment company" under the Internal Revenue Code of 1986, as amended ("Internal Revenue Code"), and avoid excise tax, the Fund may be required to distribute a portion of such discount and may be required to dispose of other portfolio securities (which may occur in periods of adverse market prices) in order to generate cash to meet these distribution requirements.

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. Although the dividend is set at a fixed or variable rate, in some circumstances it can be changed or omitted by the issuer. 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 deferral, non-cumulative dividends, subordination, liquidity, limited voting rights, and special redemption rights.

Redemption Risk — The Fund may experience periods of heavy redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. The sale of assets to meet redemption requests may create capital gains, which could cause the Fund to distribute substantial capital gains. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund, have short investment horizons, or have unpredictable cash flow needs. Heavy redemptions, whether by a few large investors or many smaller investors, could hurt the Fund's performance.

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

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

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

Reverse Repurchase Agreements — The Fund may borrow funds by entering into reverse repurchase agreements. Pursuant to such agreements, the Fund would sell portfolio securities to financial institutions such as banks and broker/dealers and agree to repurchase them at a mutually agreed-upon date and price. At the time the Fund enters into a reverse repurchase agreement, it will place in a segregated custodial account assets such as liquid high quality debt securities having a value not less than 100% of the repurchase price (including accrued interest), and will subsequently monitor the account to ensure that such required value is maintained. Reverse repurchase agreements involve the risk that the market value of the securities sold by the Fund may decline below the price at which the Fund is obligated to repurchase the securities.   Reverse repurchase agreements are considered to be borrowings by an investment company under the Investment Company Act.

Rights and Warrants — Rights are short-term warrants issued in conjunction with new stock or bond issues. Warrants are options to purchase an issuer's securities at a stated price during a stated term. If the market price of the underlying common stock does not exceed the warrant's exercise

Table of Contents

price during the life of the warrant, the warrant will expire worthless. Warrants usually have no voting rights, pay no dividends and have no rights with respect to the assets of the corporation issuing them. The percentage increase or decrease in the value of a warrant may be greater than the percentage increase or decrease in the value of the underlying common stock. Warrants may be purchased with values that vary depending on the change in value of one or more specified indices ("index warrants"). Index warrants are generally issued by banks or other financial institutions and give the holder the right, at any time during the term of the warrant, to receive upon exercise of the warrant a cash payment from the issuer based on the value of the underlying index at the time of the exercise. The market for warrants or rights may be very limited and it may be difficult to sell them promptly at an acceptable price. There is no specific limit on the percentage of assets the Fund may invest in rights and warrants.

Small Capitalization Companies Risk — Investing in the securities of small capitalization companies involves greater risk and the possibility of greater price volatility 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 interest rates, borrowing costs and earnings.

Trade Claims — The Fund may purchase trade claims and similar obligations or claims against companies in bankruptcy proceedings. Trade claims are nonsecuritized rights of payment arising from obligations that typically arise when vendors and suppliers extend credit to a company by offering payment terms for products and services. If the company files for bankruptcy, payments on these trade claims stop and the claims are subject to compromise along with the other debts of the company. Trade claims may be purchased directly from the creditor or through brokers. There is no guarantee that a debtor will ever be able to satisfy its trade claim obligations. Trade claims are subject to the risks associated with low-quality obligations.

U.S. Government Agency Securities — U.S. Government agency securities are issued or guaranteed by the U.S. Government or its agencies or instrumentalities. Some obligations issued by U.S. Government agencies and instrumentalities are supported by the full faith and credit of the U.S. Treasury; others by the right of the issuer to borrow from the U.S. Treasury; others by discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; and others only by the credit of the agency or instrumentality. U.S. Government securities bear fixed, floating or variable rates of interest. While the U.S. Government currently provides financial support to certain U.S. Government-sponsored agencies or instrumentalities, no assurance can be given that it will always do so, since it is not so obligated by law. U.S. Government securities include U.S. Treasury bills, notes and bonds, Federal Home Loan Bank obligations, Federal Intermediate Credit Bank obligations, U.S. Government agency obligations and repurchase agreements secured thereby. U.S. Government agency securities are subject to credit risk and interest rate risk.

U.S. Treasury Obligations — U.S. Treasury obligations include bills (initial maturities of one year or less), notes (initial maturities between two and ten years), and bonds (initial maturities over ten years) issued by the U.S. Treasury, Separately Traded Registered Interest and Principal component parts of such obligations known as STRIPS and inflation-indexed securities. The prices of these securities (like all debt securities) change between issuance and maturity in response to fluctuating market interest rates. U.S. Treasury obligations are subject to credit risk and interest rate risk.

Valuation Risk — This is the risk that the Fund has valued certain securities at a price different from the price at which they can be sold. This risk may be especially pronounced for investments, such as certain credit linked notes and other derivatives, which may be illiquid or which may become illiquid.

Variable or Floating Rate Obligations — The interest rates payable on certain fixed income securities in which the Fund may invest are not fixed and may fluctuate based upon changes in market rates. A variable rate obligation has an interest rate which is adjusted at predesignated periods in response to changes in the market rate of interest on which the interest rate is based. Variable and floating rate obligations are less effective than fixed rate instruments at locking in a particular yield. Nevertheless, such obligations may fluctuate in value in response to interest rate changes if there is a delay between changes in market interest rates and the interest reset date for the obligation, or for other reasons.

The Fund may invest in floating rate debt instruments ("floaters") and engage in credit spread trades. The interest rate on a floater is a variable rate which is tied to another interest rate, such as a money-market index or Treasury bill rate. The interest rate on a floater resets periodically, typically every six months. While, because of the interest rate reset feature, floaters provide the Fund with a certain degree of protection against rises in interest rates, the Fund will participate in any declines in interest rates as well. A credit spread trade is an investment position relating to a difference in the prices or interest rates of two securities or currencies, where the value of the investment position is determined by movements in the difference between the prices or interest rates, as the case may be, of the respective securities or currencies.

When-Issued and Forward Commitment Transactions — These transactions involve a commitment by the Fund to purchase or sell securities at a future date. These transactions enable the Fund to "lock-in" what the Manager or the sub-advisor, as applicable, believes to be an attractive price or yield on a particular security for a period of time, regardless of future changes in interest rates. For instance, in periods of rising interest rates and falling prices, the Fund might sell securities it owns on a forward commitment basis to limit its exposure to falling prices. In periods of falling interest rates and rising prices, the Fund might purchase a security on a when-issued or forward commitment basis and sell a similar security to settle such purchase, thereby obtaining the benefit of currently higher yields. If the other party fails to complete the trade, the Fund may lose the opportunity to obtain a favorable price. For purchases on a when-issued basis, the price of the security is fixed at the date of purchase, but delivery of and payment for the securities is not set until after the securities are issued. The value of when-issued securities is subject to market fluctuation during the interim period and no income accrues to the Fund until settlement takes place. Such transactions therefore involve a risk of loss if the value of the security to be purchased declines prior to the settlement date or if the value of the security to be sold increases prior to the settlement date. A sale of a when-issued security also involves the risk that the other party will be unable to settle the transaction. Forward commitment transactions involve a commitment to purchase or sell securities with payment and delivery to take place at some future date, normally one to two months after the date of the transaction. The payment obligation and interest rate are fixed at the time the buyer enters into the forward commitment. Forward commitment transactions are typically used as a hedge against anticipated changes in interest rates and prices. Forward commitment transactions are executed for existing obligations, whereas in a when-issued transaction, the obligations have not yet been issued.

Table of Contents

The Fund maintains with its custodian segregated (or earmarked) liquid securities in an amount at least equal to the when-issued or forward commitment transaction. When entering into a when-issued or forward commitment transaction, the Fund will rely on the other party to consummate the transaction; if the other party fails to do so, the Fund may be disadvantaged.

OTHER INVESTMENT STRATEGIES AND RISKS

In addition to the investment strategies and risks described in the Prospectus, the Fund may:

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

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

Loan securities to broker-dealers or other institutional investors. Securities loans will not be made if, as a result, the aggregate amount of all outstanding securities loans by the Fund exceeds 33 ^1/3 % of its total assets (including the market value of collateral received). For purposes of complying with the Fund's investment policies and restrictions, collateral received in connection with securities loans is deemed an asset of the Fund to the extent required by law.

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

Purchase securities sold in private placement offerings made in reliance on the "private placement" exemption from registration afforded by Section 4(a)(2) of the Securities Act, and resold to qualified institutional buyers under Rule 144A under the Securities Act. The Fund will not invest more than 15% of its net assets in Section 4(a)(2) securities and illiquid securities unless the Manager or the sub-advisor, as applicable, determines, by continuous reference to the appropriate trading markets and pursuant to guidelines approved by the Trust's Board of Trustees ("Board") that any Section 4(a)(2) securities held by the Fund in excess of this level are at all times liquid.

INVESTMENT RESTRICTIONS

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

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

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

The following restrictions have been adopted by the Fund and may be changed with respect to the Fund only by the majority vote of the Fund's outstanding interests. "Majority of the outstanding voting securities" under the 1940 Act and as used herein means, with respect to the Fund, the lesser of (a) 67% of the shares of the Fund present at the meeting if the holders of more than 50% of the shares are present and represented at the shareholders' meeting or (b) more than 50% of the shares of the Fund.

The Fund may not:

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

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

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

Table of Contents

Lend any security or make any other loan except (i) as otherwise permitted under the 1940 Act, (ii) pursuant to a rule, order or interpretation issued by the SEC or its staff, (iii) through the purchase of a portion of an issue of debt securities in accordance with the Fund's investment objective, policies and limitations, or (iv) by engaging in repurchase agreements.

Issue any senior security except as otherwise permitted (i) under the 1940 Act or (ii) pursuant to a rule, order or interpretation issued by the SEC or its staff.

Borrow money, except as otherwise permitted under the 1940 Act or pursuant to a rule, order or interpretation issued by the SEC or its staff, including (i) as a temporary measure, (ii) by entering into reverse repurchase agreements, and (iii) by lending portfolio securities as collateral. For purposes of this investment limitation, the purchase or sale of options, futures contracts, options on futures contracts, forward contracts, swaps, caps, floors, collars and other similar financial instruments shall not constitute borrowing.

Invest more than 25% of its assets in the securities of companies primarily engaged in any particular industry or group of industries provided that this limitation does not apply to: (i) obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities; and (ii) tax-exempt securities issued by municipalities or their agencies and authorities.

The above percentage limits (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 commodities set forth in (2) above, the Fund does not consider foreign currencies or forward contracts to be physical commodities.

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, the Manager may analyze the characteristics of a particular issuer and instrument and may assign an industry classification consistent with those characteristics. The Manager 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 single 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 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 policy of not being concentrated in any particular industry or group of industries.

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

Invest more than 15% of its net assets in illiquid securities, including time deposits and repurchase agreements that mature in more than seven days; or

Purchase securities on margin, except that (1) the Fund may obtain such short term credits as necessary for the clearance of transactions, and (2) the Fund may make margin payments in connection with foreign currency, futures contracts, options, forward contracts, swaps, caps, floors, collars, securities purchased or sold on a forward-commitment or delayed-delivery basis or other financial instruments.

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

TEMPORARY DEFENSIVE INVESTMENTS

In times of unstable or adverse market, economic, political or other conditions, where the Manager or a 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. It can also hold cash or purchase these types of securities for liquidity purposes to meet cash needs due to redemptions of Fund shares, or to hold while waiting to invest cash received from purchases of Fund shares or the sale of other portfolio securities.

These temporary investments can include (i) obligations issued or guaranteed by the U.S. Government, its agents 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 a 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.

DISCLOSURE OF PORTFOLIO HOLDINGS

The Fund publicly discloses portfolio holdings information as follows:

a complete list of holdings for the Fund on an annual and semi-annual basis in the reports to shareholders within sixty days of the end of each fiscal semi-annual period and in publicly available filings of Form N-CSR with the SEC within ten days thereafter;

a complete list of holdings for the Fund as of the end of its first and third fiscal quarters in publicly available filings of Form N-Q with the SEC within sixty days of the end of the fiscal quarter;

a complete list of holdings for the Fund as of the end of each quarter on the Funds' website (www.americanbeaconfunds.com) approximately sixty days after the end of the quarter; and

ten largest holdings for the Fund as of the end of each calendar quarter on the Funds' website (www.americanbeaconfunds.com) and in sales materials approximately fifteen days after the end of the calendar quarter.

Public disclosure of the Fund's holdings on the website and in sales materials may be delayed when an investment manager informs the Fund that such disclosure could be harmful to the Fund. In addition, individual holdings may be omitted from website and sales material disclosure, when such omission is deemed to be in the Fund's best interest.

Disclosure of Nonpublic Holdings .

Occasionally, certain interested parties — including individual investors, institutional investors, intermediaries that distribute shares of the Fund, third-party service providers, rating and ranking organizations, and others — may request portfolio holdings information that has not yet been publicly disclosed by the Fund. The 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 Policy and Procedures for Disclosure of Portfolio Holdings Information (the "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 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-advisors 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 Trust's Board of Trustees fulfills a legitimate business purpose, is in in the best interest of Fund shareholders, and each Trustee is subject to a duty of confidentiality.

The Fund has ongoing arrangements to provide nonpublic holdings information to the following service providers:

Certain third parties are provided with nonpublic holdings information (either complete or partial lists) by the Manager or another service provider on an ad hoc basis. These third parties include: broker-dealers, prospective sub-advisors, borrowers of the Fund's portfolio securities, pricing services, legal counsel, and issuers (or their agents). Broker-dealers utilized by the Fund in the process of purchasing and selling portfolio securities or providing market quotations receive limited holdings information on a current basis with no lag. The Manager provides current holdings to investment managers

Table of Contents

being considered for appointment as a sub-advisor to the Fund. If the Fund participates in securities lending activities, potential borrowers of the Fund's securities receive information pertaining to the Fund's securities available for loan. Such information is provided on a current basis with no lag. The Fund utilizes various pricing services to supply market quotations and evaluated prices to State Street. State Street and the Manager may disclose current nonpublic holdings to those pricing services. An investment manager may provide holdings information to legal counsel when seeking advice regarding those holdings. From time to time, an issuer (or its agent) may contact the Fund requesting confirmation of ownership of the issuer's securities. Such holdings information is provided to the issuer (or its agent) as of the date requested. The Fund does not have written contractual arrangements with these third parties regarding the confidentiality of the holdings information. However, the Fund would not continue to utilize a third party that the Manager determined to have misused nonpublic holdings information.

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

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

Under the Holdings Policy, disclosure of nonpublic portfolio holdings information to parties other than those discussed above must meet all of the following conditions:

Recipients of portfolio holdings information must agree in writing to keep the information confidential until it has been posted to the Fund's website and not to trade based on the information;

Holdings may only be disclosed as of a month-end date;

No compensation may be paid to the Fund's the Manager or any other party in connection with the disclosure of information about portfolio securities; and

A member of the Manager's Compliance staff must approve requests for nonpublic holdings information.

In determining whether to approve a request for portfolio holdings disclosure by the Manager, Compliance staff generally considers 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 it deems relevant. Any potential conflicts between shareholders and affiliated persons of the Fund that arise as a result of a request for portfolio holdings information shall be decided by the Manager in the best interests of shareholders. However, if a conflict exists between the interests of shareholders and the Manager, the Manager may present the details of the request to the Board for a determination to either approve or deny the request. 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 Compliance staff 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 sub-advisor to the Fund may manage substantially similar portfolio 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 33 ^1/3 % 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 U.S. dollars, foreign currency, or securities issued or fully guaranteed by the U.S. Government 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 pay the borrower a pre-negotiated fee or "rebate" from any return earned on the investment. 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. Loans are made only to borrowers that are deemed by the Manager to present acceptable credit risk on a fully collateralized basis. 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 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, Brown Brothers Harriman & Co. The amount of such compensation depends on the income generated by the loan of the securities. The Fund receives compensation that includes, but is not limited to, fee income in lieu of dividends and interest, or the equivalent, as applicable, on the securities loaned and interest on the investment of the cash collateral.

Currently, the Fund does not intend to engage in securities lending activities.

Taxation of Certain Investments and Strategies

If the Fund acquires stock in a foreign corporation that is a "passive foreign investment company" ("PFIC") (generally, any foreign corporation, with certain exceptions, that, in general, meets either of the following tests for the taxable year: (1) at least 75% of its gross income is passive or (2) an average of at least 50% of its assets produce, or are held for the production of, passive income) and holds the stock beyond the end of the year of acquisition, the Fund will be subject to federal income tax on any "excess distribution" it receives on the stock and of any gain it realizes from disposition of that stock (collectively "PFIC income"), plus interest thereon, even if the Fund distributes the PFIC income as a taxable dividend to its shareholders. Fund distributions thereof will not be eligible for the 15% and 20% maximum federal income tax rates on individuals' "qualified dividend income" described in the Prospectus. The Fund may avoid this tax and interest if it elects to treat the PFIC as a "qualified electing fund"; however, the requirements for that election are difficult to satisfy. If such an election were made, the Fund would be required to include in its income each taxable year a portion of the ordinary income and net capital gains of the PFIC, even if the income and gains were not distributed to the Fund. Any such income and gains would be subject to the Distribution Requirement and to the calendar year Excise Tax distribution requirement.

Alternatively, the Fund may elect to "mark-to-market" its stock in a PFIC it owns at the end of its taxable year. Under such an election, the Fund (1) would include in gross income each taxable year (and treat as ordinary income) an amount equal to the excess, if any, of the fair market value of the PFIC stock as of the close of the taxable year over the Fund's adjusted basis in the PFIC stock and (2) would be allowed a deduction (as an ordinary, not a capital, loss) for the excess, if any, of its adjusted basis in the PFIC stock over the fair market value of the PFIC stock as of the close of the taxable

Table of Contents

year, but only to the extent of any net mark-to-market gains included by the Fund for prior taxable years. The Fund's adjusted basis in the PFIC stock would be adjusted to reflect the amounts included in income, or deducted, under this election. Any gain or loss realized on the sale or other disposition of the PFIC stock, would be treated as ordinary income or loss. The Fund would not be subject to the deferred tax and interest charge discussed above with respect to PFIC stock for which a mark-to-market election has been made.

Investors should be aware that the Fund may not be able, at the time it acquires a foreign corporation's shares, to ascertain whether the corporation is a PFIC and that a foreign corporation may become a PFIC after the Fund acquires shares therein.  While the Fund generally will seek to minimize its investments in PFIC shares, and to make appropriate elections when they are available, to lessen the adverse tax consequences described above, there are no guarantees that it will be able to do so, and it reserves the right to make such investments as a matter of its investment policy.

Hedging strategies, such as entering into forward contracts and selling (writing) and purchasing options and futures contracts, involve complex rules that will determine for federal income tax purposes the amount, character and timing of recognition of gains and losses the Fund may realize in connection therewith. In general, the Fund's (1) gains from the disposition of foreign currencies and (2) gains from options, futures and forward contracts derived with respect to its business of investing in securities or foreign currencies will be treated as qualifying income under the Gross Income Requirement.

The Fund may invest in one or more limited liability companies ("LLCs") and limited partnerships ("LPs") that will be classified for federal tax purposes as partnerships (and, except as expressly stated below, this discussion assumes that classification). LLCs and LPs in which the Fund may invest may include (1) a "publicly traded partnership" (that is, a partnership the interests in which are "traded on an established securities market" or "readily tradable on a secondary market (or the substantial equivalent thereof)") (a "PTP"), which may be a QPTP, or (2) a non-PTP at least 90% of the income of which satisfies the Gross Income Requirement.

If an LLC or LP in which the Fund invests is a QPTP, all its net income (regardless of source) will be qualifying income to the Fund under the Gross Income Requirement. The Fund's investment in QPTPs, together with certain other investments, however, may not exceed 25% of the value of its total assets at the end of each quarter of its taxable year in order to satisfy one of the Diversification Requirements. In addition,if the Fund holds more than 10% of a QPTP's equity securities, none of those securities will count toward its satisfying those requirements.

With respect to non-QPTPs, (1) if an LLC or LP (including a PTP) is treated for federal tax purposes as a corporation, distributions from it to the Fund might be treated as "qualified dividend income" and disposition of the Fund's interest therein would generate gain or loss from the disposition of a security, or (2) if such an LLC or LP is not treated as a corporation, the Fund would be treated as having earned its proportionate share of each item of income the LLC or LP earned. In the latter case, the Fund would be able to treat its share of the entity's income as qualifying income under the Gross Income Requirement only to the extent that income would be qualifying income if realized directly by the Fund in the same manner as realized by the LLC or LP.  Certain LLCs and LPs (e.g., private funds) in which the Fund may invest may generate income and gains that are not qualifying income under the Gross Income Requirement. The Fund will monitor its investments in LLCs and LPs to assure its compliance with the requirements for qualification as a RIC.

Dividends and interest the Fund receives, and gains it realizes, on foreign securities may be subject to income, withholding or other taxes imposed by foreign countries and U.S. possessions (collectively, "foreign taxes") that would reduce the yield and/or total return on its securities. Tax treaties between certain countries and the United States may reduce or eliminate those taxes, however, and many foreign countries do not impose taxes on capital gains on investments by foreign investors.  It is impossible to determine the effective rate of foreign tax in advance, since the amount of the Fund's assets to be invested in various countries is not known.

Some futures contracts, foreign currency contracts, and "nonequity" options ( i.e. , certain listed options, such as those on a "broad-based" securities index) - except any "securities futures contract" that is not a "dealer securities futures contract" (both as defined in the Internal Revenue Code) and any interest rate swap, currency swap, basis swap, interest rate cap, interest rate floor, commodity swap, equity swap, equity index swap, credit default swap, or similar agreement - in which the Fund invests may be subject to Internal Revenue Code section 1256 (collectively, "Section 1256 contracts"). Any Section 1256 contracts the Fund holds at the end of its taxable year must be "marked-to-market" (that is, treated as having been sold at that time for its fair market value) for federal tax purposes, with the result that unrealized gains or losses will be treated as though they were realized. Sixty percent of any net gain or loss realized on these deemed sales, and 60% of any net realized gain or loss from any actual sales of Section 1256 contracts, will be treated as long-term capital gain or loss, and the balance will be treated as short-term capital gain or loss. Section 1256 contracts also may be marked-to-market for purposes of the Excise Tax. These rules may operate to increase the amount that the Fund must distribute to satisfy the Distribution Requirement ( i.e. with respect to the portion treated as short-term capital gain), which will be taxable to its shareholders as ordinary income when distributed to them, and to increase the net capital gain the Fund recognizes, without in either case increasing the cash available to it.

Section 988 of the Internal Revenue Code also may apply to the Fund's forward currency contracts and options and futures on foreign currencies. Under that section, each foreign currency gain or loss generally is computed separately and treated as ordinary income or loss. These gains or losses will increase or decrease the amount of the Fund's investment company taxable income to be distributed to its shareholders as ordinary income, rather than affecting the amount of its net capital gain. If section 988 losses exceed other investment company taxable income during a taxable year, the Fund would not be able to distribute any dividends, and any distributions made during that year before the losses were realized would be recharacterized as a return of capital to shareholders, rather than as a dividend, thereby reducing each shareholder's basis in his or her Fund shares.

Offsetting positions the Fund enters into or holds in any actively traded option, futures or forward contract may constitute a "straddle" for federal income tax purposes. Straddles are subject to certain rules that may affect the amount, character and timing of the Fund's gains and losses with respect to positions of the straddle by requiring, among other things, that (1) losses realized on disposition of one position of a straddle be deferred to the extent of any unrealized gain in an offsetting position until the latter position is disposed of, (2) the Fund's holding period in certain straddle positions not begin until the straddle is terminated (possibly resulting in gain being treated as short-term rather than long-term capital gain) and (3) losses recognized with respect to certain straddle positions, that otherwise would constitute short-term capital losses, be treated as long-term capital losses. Applicable regulations also provide certain "wash sale" rules, which apply to transactions where a position is sold at a loss and a new offsetting

Table of Contents

position is acquired within a prescribed period, and "short sale" rules applicable to straddles. Different elections are available, that may mitigate the effects of the straddle rules, particularly with respect to "mixed straddles" (i.e., a straddle at least one, but not all, positions of which are Section 1256 contracts).

When a covered call option written (sold) by the Fund expires, it will realize a short-term capital gain equal to the amount of the premium it received for writing the option. When the Fund terminates its obligations under such an option by entering into a closing transaction, it will realize a short-term capital gain (or loss), depending on whether the cost of the closing transaction is less (or more) than the premium it received when it wrote the option.  When a covered call option written by the Fund is exercised, it will be treated as having sold the underlying security, producing long-term or short-term capital gain or loss, depending on the holding period of the underlying security and whether the sum of the option price received on the exercise plus the premium received when it wrote the option is more or less than the underlying security's basis.

If the Fund has an "appreciated financial position" - generally, any position (including an interest through an option, futures or forward contract or short sale) with respect to any stock, debt instrument (other than "straight debt") or partnership interest the fair market value of which exceeds its adjusted basis - and enters into a "constructive sale" of the position, the Fund will be treated as having made an actual sale thereof, with the result that it will recognize gain at that time. A constructive sale generally consists of a short sale, an offsetting notional principal contract or a futures or forward contract the Fund or a related person enters into with respect to the same or substantially identical property. In addition, if the appreciated financial position is itself a short sale or such a contract, acquisition of the underlying property or substantially identical property will be deemed a constructive sale. The foregoing will not apply, however, to any Fund transaction during any taxable year that otherwise would be treated as a constructive sale if the transaction is closed within 30 days after the end of that year and the Fund holds the appreciated financial position unhedged for 60 days after that closing (i.e., at no time during that 60-day period is the Fund's risk of loss regarding that position reduced by reason of certain specified transactions with respect to substantially identical or related property, such as having an option to sell, being contractually obligated to sell, making a short sale or granting an option to buy substantially identical stock or securities).

Certain aspects of the tax treatment of derivative instruments, including certain equity index options and futures, are currently unclear and may be affected by changes in legislation, regulations or other legally binding authority that could affect the treatment of income from those instruments, and the character, timing and amount of the Fund's taxable income or gains and distributions. If the Internal Revenue Service ("IRS") were to assert successfully that income the Fund derives from those investments does not constitute qualifying income, the Fund might cease to qualify as a RIC (with the consequences described above under "Taxation of the Fund") or might be required to reduce its exposure to such investments.

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

Basis Election and Reporting
Fund shareholders who want to use an acceptable method for basis determination with respect to Fund shares other than the average basis method (the Fund's default method), must elect to do so in writing (which may be electronic).  The basis determination method the Fund shareholder elects may not be changed with respect to a redemption of shares after the settlement date of the redemption.

In addition to the requirement to report the gross proceeds from the redemption of shares, the Fund (or its administrative agent) must report to the IRS and furnish to its shareholders the basis information for Fund shares that are redeemed and indicate whether they had a short-term (one year or less) or long-term (more than one year) holding period. Fund shareholders should consult with their tax advisors to determine the best IRS-accepted basis determination method for their tax situation and to obtain more information about how the basis reporting law applies to them. Fund shareholders who acquire and hold shares through a financial intermediary should contact their financial intermediary for information related to the basis election and reporting.

Backup Withholding
The Fund is required to withhold and remit to the U.S. Treasury 28% of dividends, capital gain distributions, and redemption proceeds (regardless of the extent to which gain or loss may be realized) otherwise payable to any individual shareholder who fails to certify that the taxpayer identification number furnished to the Fund is correct or who furnishes an incorrect number (together with the withholding described in the next sentence, "backup withholding"). Withholding at that rate also is required from the Fund's dividends and capital gain distributions otherwise payable to such a shareholder who (1) is subject to backup withholding for failure to report the receipt of interest or dividend income properly or (2) fails to certify to the Fund that he or she is not subject to backup withholding or that it is a corporation or other "exempt recipient." Backup withholding is not an additional tax; rather, any amounts so withheld may be credited against your federal income tax liability or refunded.

Non-U.S. Shareholders
Dividends from the Fund's investment company taxable income that are paid to a shareholder who is a non-resident alien individual or foreign entity (a "non-U.S. person") generally are subject to 30% federal withholding tax unless a reduced rate of withholding or a withholding exemption is provided under an applicable treaty. For taxable years that began before January 1, 2015, however, two categories of dividends, "short-term capital gain dividends" and "interest-related dividends," paid by a RIC to non-U.S. shareholers (with certain exceptions) were exempt from that tax. "Short-term capital gain dividends" are dividends that are attributable to net short-term gain, computed with certain adjustments. "Interest-related dividends" are dividends that are attributable to "qualified net interest income" (i.e., "qualified interest income," which generally consists of certain original issue discount, interest on obligations "in registered form," and interest on deposits, less allocable deductions) from sources within the United States. The

Table of Contents

period for the applicability of the exemption from withholding tax for those dividends has frequently been extended by legislation in the past. Non-U.S. persons are urged to consult their own tax advisers concerning the applicability of that withholding tax.

Foreign Account Tax Compliance Act ("FATCA")
Under FATCA, "foreign financial institutions" ("FFIs") and "non-financial foreign entities" ("NFFEs") that are Fund shareholders may be subject to a generally nonrefundable 30% withholding tax on (1) income dividends the Fund pays, and (2) certain capital gain distributions and the proceeds of redemptions of Fund shares it pays after December 31, 2018. As discussed below, the FATCA withholding tax generally can be avoided (a) by an FFI, if it reports certain information regarding direct and indirect ownership of financial accounts U.S. persons hold with the FFI, and (b) by an NFFE, if it certifies its status as such and, in certain circumstances, that (i) it has no substantial U.S. persons as owners or (ii) it does have such owners and reports information relating to them to the withholding agent (which may be the Fund).

The U.S. Treasury Department has negotiated intergovernmental agreements ("IGAs") with certain countries and is in various stages of negotiations with other foreign countries with respect to alternative approaches to implement FATCA. An entity in one of those countries may be required to comply with the terms of the IGA instead of U.S. Treasury regulations, as described below.

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

An FFI resident in a country that has entered into a Model I IGA with the United States must report to that country's government (pursuant to the terms of the applicable IGA and applicable law), which will, in turn, report to the IRS. An FFI resident in a Model II IGA country generally must comply with U.S. regulatory requirements, with certain exceptions, including the treatment of recalcitrant account holders. An FFI resident in one of those countries that complies with whichever of the foregoing applies will be exempt from FATCA withholding.

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

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

DESCRIPTION OF THE TRUST

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

The Trust was originally created to manage money for large institutional investors, including pension and 401(k) plans for American Airlines Group, Inc. The following individuals (and members of that individual's "immediate family"), are eligible to purchase shares of the Institutional Class with an initial investment of less than $250,000 (i) employees of the Manager, (ii) employees of a sub-advisor for Funds where it serves as sub-advisor, (iii) members of the Board, (iv) employees of Kelso/Estancia, and (v) members of the Manager's Board of Directors. The term "immediate family" refers to one's spouse, children, grandchildren, grandparents, parents, parents-in-law, brothers and sisters, sons and daughters-in-law, a sibling's spouse, a spouse's sibling, aunts, uncles, nieces and nephews; relatives by virtue of remarriage (step-children, step-parents, etc.) are included. Any shareholders that the Manager transfers to the Institutional Class upon termination of the class of shares in which the shareholders were originally invested is also eligible for purchasing shares of the Institutional Class with an initial investment of less than $250,000.

The Investor Class was created to give individuals and other smaller investors an opportunity to invest in the American Beacon Funds. The Institutional and Y Classes were created to manage money for large institutional investors, including pension and 401(k) plans. The A Class and C Class were created for investors investing in the Funds through their broker-dealers or other financial intermediaries.  The SP Class was created to provide holders of the Investor Class shares of the Acquired Sound Point Fund with a comparable share class after the reorganization of the Acquired Sound Point Fund into the Fund.
