American Beacon DoubleLine Floating Rate Fund | Asset-Backed Securities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Asset-Backed Securities Risk
Investments in asset-backed securities are influenced by factors affecting the assets underlying the securities, including the broader market sector and individual markets, such as the auto markets. These securities may be more sensitive to changes in interest rates than other types of debt securities. Investments in asset-backed securities also are subject to risks of fixed-income securities, which include, but are not limited to, credit risk, interest rate risk, prepayment and extension risk, callable securities risk, valuation risk, liquidity risk, and restricted securities risk. A decline in the credit quality of the issuers of asset-backed securities or instability in the markets for such securities may affect the value and liquidity of such securities, which could result in losses to the Fund. These securities are also subject to the risk of default on the underlying assets, particularly during periods of market downturn, and an unexpectedly high rate of defaults on the underlying assets will adversely affect the security’s value.

American Beacon DoubleLine Floating Rate Fund | Asset Selection Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Asset Selection Risk
Assets selected for the Fund may not perform to expectations. This could result in the Fund’s underperformance compared to other funds with similar investment objectives.

American Beacon DoubleLine Floating Rate Fund | Callable Securities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

American Beacon DoubleLine Floating Rate Fund | Collateralized Debt Obligations CDO Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Collateralized Debt Obligations (“CDO”) Risk
The risks of an investment in a CDO, including a CBO or CLO, depend largely on the quality and type of the collateral and the tranche of the CDO in which the Fund invests. Normally, collateralized bond obligations, CLOs and other CDOs are privately offered and sold, and thus are not registered under the securities laws. As a result, investments in CDOs maybe illiquid. In addition to the risks associated with debt instruments (e.g., interest rate risk and credit risk), CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the Fund may invest in CDOs that are subordinate to other classes of the issuer’s securities; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

American Beacon DoubleLine Floating Rate Fund | Collateralized Loan Obligations CLOs Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

American Beacon DoubleLine Floating Rate Fund | Confidential Information Access Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Confidential Information Access Risk
In managing the Fund or other client assets, the Manager or sub-advisor may be in possession of material non-public information about the issuers of certain investments, including, without limit, loans, high yield bonds and related investments being considered for acquisition by the Fund or held in the Fund’s portfolio. Because of prohibitions on trading in securities of issuers while in possession of such information, the Fund might be unable to enter into a transaction in a security of that issuer when it would otherwise be advantageous to do so. In such circumstances, the Fund may be disadvantaged in comparison to other investors, including with respect to the price the Fund pays or receives when it buys or sells an investment. Pursuant to applicable policies and procedures, the Manager or sub-advisor may, but is not required to, seek to avoid receipt of confidential information from the issuer so as to avoid possible restrictions on its ability to purchase and sell investments on behalf of the Fund.

American Beacon DoubleLine Floating Rate Fund | Counterparty Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Counterparty Risk
The Fund is subject to the risk that a party or participant to a transaction, such as a broker, will be unwilling or unable to satisfy its obligation to make timely principal, interest or settlement payments or to otherwise honor its obligations to the Fund.

American Beacon DoubleLine Floating Rate Fund | Covenant-Lite Obligations Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

American Beacon DoubleLine Floating Rate Fund | Credit Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Credit Risk
The Fund is subject to the risk that the issuer, guarantor or insurer of an obligation, or the counterparty to a transaction, may fail, or become less able or unwilling, to make timely payment of interest or principal or otherwise honor its obligations or default completely. Changes in the actual or perceived creditworthiness of an issuer, or a downgrade or default affecting any of the Fund’s securities, could affect the Fund’s performance. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

American Beacon DoubleLine Floating Rate Fund | Currency Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Currency Risk
The Fund may have exposure to foreign currencies. Foreign currencies may fluctuate significantly over short periods of time, may be affected unpredictably by intervention, or the failure to intervene, of the U.S. or foreign governments or central banks, and may be affected by currency controls or political developments in the U.S. or abroad. Foreign currencies may also decline in value relative to the U.S. dollar and other currencies and thereby affect the Fund’s investments.

American Beacon DoubleLine Floating Rate Fund | Cybersecurity and Operational Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

American Beacon DoubleLine Floating Rate Fund | Debentures Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

American Beacon DoubleLine Floating Rate Fund | Debtor-in-Possession DIP Financing, Rescue Financing, and Exit Financing Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Debtor-in-Possession (“DIP”) Financing, Rescue Financing, and Exit Financing Risk
The Fund may invest in obligations of companies that have filed for protection under Chapter 11 of the United States Bankruptcy Code. DIP financings allow the entity to continue its business operations while reorganizing under Chapter 11, and such financings must be approved by the bankruptcy court. DIP financings are typically fully secured by a lien on the debtor’s otherwise unencumbered assets or secured by a junior lien on the debtor’s encumbered assets (so long as the obligation is fully secured based on the most recent current valuation or appraisal report of the debtor). There is a risk that the borrower will not emerge from Chapter 11 bankruptcy proceedings and be forced to liquidate its assets under Chapter 7 of the U.S. Bankruptcy Code. In the event of liquidation, the Fund’s only recourse will be against the property securing the DIP financing.

The Fund may invest in exit financing, also known as an exit facility, which is the financing provided to companies that have filed for protection under Chapter 11 of the United States Bankruptcy Code to allow them to emerge from bankruptcy. The Fund may also invest in obligations of companies receiving rescue financing to address liquidity shortfalls, temporary operational problems, pending debt maturities or over-leveraged balance sheets. These financial difficulties may never be overcome and may lead to uncertain outcomes, including causing such issuer to become subject to bankruptcy proceedings.

American Beacon DoubleLine Floating Rate Fund | Defaulted Securities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Defaulted Securities Risk
There is a significant risk related to the uncertainty of repayment of defaulted securities (e.g., a security on which a principal or interest payment is not made when due) and obligations of distressed issuers (including insolvent issuers or issuers in payment or covenant default, in workout or restructuring or in bankruptcy or similar proceedings). Such investments entail high risk and have speculative characteristics.

American Beacon DoubleLine Floating Rate Fund | Delayed Funding Loans and Revolving Credit Facilities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Delayed Funding Loans and Revolving Credit Facilities Risk
The Fund’s investments in delayed funding loans and revolving credit facilities are subject to credit risk, interest rate risk, liquidity risk and loan interests risk. There may be circumstances in which the borrower’s credit risk may be deteriorating and yet the Fund may be obligated to make loans to the borrower as the borrower’s credit continues to deteriorate, including at a time when the borrower’s financial condition makes it unlikely that such amounts will be repaid.

American Beacon DoubleLine Floating Rate Fund | Emerging Markets Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Emerging Markets Risk
When investing in emerging markets, the risks of investing in foreign securities are heightened. Emerging markets are generally smaller, less developed, less liquid and more volatile than the securities markets of the U.S. and other developed markets. There are also risks of: greater political or economic uncertainties; an economy’s dependence on revenues from particular commodities or on international aid or development assistance; currency transfer restrictions; a limited number of potential buyers for such securities resulting in increased volatility and limited liquidity for emerging market securities; trading suspensions and other restrictions on investment; delays and disruptions in securities clearing and settlement procedures; and significant limitations on investor rights and recourse. The governments of emerging market countries may also be more unstable and more likely to impose capital controls, nationalize a company or industry, place restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, intervene in the financial markets, and/or impose burdensome taxes that could adversely affect security prices. In addition, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing, financial reporting and recordkeeping standards and requirements comparable to those to which U.S. companies are subject.

American Beacon DoubleLine Floating Rate Fund | Foreign Investing Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks may include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing, recordkeeping and financial reporting standards, (5) greater volatility, (6) different government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays or failures in transaction payment and settlement in some foreign markets. Additionally, trading in foreign markets generally involves higher transaction costs than trading in U.S. markets. The Fund’s investment in a foreign issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with that country, including tariffs, trade disputes and sanctions. Global economic and financial markets have become increasingly interconnected and conditions (including recent volatility, terrorism, war and political instability) and events (including natural disasters) in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

American Beacon DoubleLine Floating Rate Fund | High Portfolio Turnover Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

High Portfolio Turnover Risk
Portfolio turnover is a measure of the Fund’s trading activity over a one-year period. The Fund may engage in active and frequent trading, which could increase the Fund’s transaction costs, have a negative impact on performance, and generate higher capital gain distributions to shareholders than if the Fund had lower portfolio turnover.

American Beacon DoubleLine Floating Rate Fund | High-Yield Securities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

High-Yield Securities Risk
Exposure to high-yield, below investment-grade securities (commonly referred to as “junk bonds”) generally involves significantly greater risks than an investment in investment grade securities. High-yield debt securities may fluctuate more widely in price and yield and may fall in price when the economy is weak or expected to become weak. These securities also may be difficult to sell at the time and price the Fund desires. High-yield securities are considered to be speculative with respect to an issuer’s ability to pay interest and principal and carry a greater risk that the issuers of lower-rated securities will default on the

timely payment of principal and interest. High-yield securities may experience greater price volatility and less liquidity than investment grade securities. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment.

American Beacon DoubleLine Floating Rate Fund | Inflation Index-Linked Securities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Inflation Index-Linked Securities Risk
Unlike a conventional bond, whose issuer makes regular fixed interest payments and repays the face value of the bond at maturity, an inflation index-linked security provides principal payments and interest payments that vary as the principal and/or interest are adjusted over time to reflect a rise or a drop in the reference inflation-related index. For inflation index-linked debt securities for which repayment of the original principal upon maturity (as adjusted for inflation) is not guaranteed, the adjusted principal value of the securities repaid at maturity may be less than the original principal value. The value of inflation index-linked securities is expected to change in response to real interest rates, which are in turn tied to the relationship between nominal interest rates and the rate of inflation. There can be no assurance that an inflation index that is used will accurately measure the real rate of inflation. The price of an inflation index-linked security generally falls when real interest rates rise and rises when real interest rates fall. Interest payments on such securities are unpredictable and will fluctuate as the principal and interest are adjusted to reflect movements in the inflation-related index. In periods of deflation, the Fund may have no income at all from such investments. The principal value of an investment in the Fund is not protected or otherwise guaranteed by the value of the Fund’s investments in inflation index-linked securities.

American Beacon DoubleLine Floating Rate Fund | Interest Rate Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Interest Rate Risk
Generally, the value of investments with interest rate risk, such as fixed-income securities, will move in the opposite direction as movements in interest rates. Factors including central bank monetary policy, rising inflation rates, and changes in general economic conditions may cause interest rates to rise, which could cause the value of the Fund’s investments to decline. Interest rate increases, including significant or rapid increases, may result in a decline in the value of bonds held by the Fund, make issuers less willing or able to make principal and interest payments on fixed-income investments when due, lead to heightened volatility in the fixed-income markets and adversely affect the liquidity of certain fixed-income investments, any of which may result in substantial losses to the Fund. When interest rates decline, issuers may prepay higher-yielding securities held by the Fund, resulting in the Fund reinvesting in securities with lower yields, which may cause a decline in its income. Interest rate changes may have a more pronounced effect on the market value of fixed-rate instruments than on floating-rate instruments. The value of floating rate and variable securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The prices of fixed-income securities are also affected by their durations. Fixed-income securities with longer durations generally have greater sensitivity to changes in interest rates than those with shorter durations. Rising interest rates may cause the value of the Fund’s investments with longer durations and terms to maturity to decline, which may adversely affect the value of the Fund. For example, if a bond has a duration of two years, a 1% increase in interest rates could be expected to result in a 2% decrease in the value of the bond. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund.

American Beacon DoubleLine Floating Rate Fund | Investment Risk [Member]

Risk [Text Block]

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

American Beacon DoubleLine Floating Rate Fund | Issuer Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

American Beacon DoubleLine Floating Rate Fund | Liquidity Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may have limited marketability, be subject to restrictions on sale, be difficult or impossible to purchase or sell at favorable times or prices or become less liquid in response to market developments or adverse credit events that may affect issuers or guarantors of a security. An inability to sell a portfolio position can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Market prices for such instruments may be volatile. During periods of substantial market volatility, an investment or even an entire market segment may become illiquid, sometimes abruptly, which can adversely affect the Fund’s ability to limit losses. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund. Unexpected redemptions may force the Fund to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

American Beacon DoubleLine Floating Rate Fund | Litigation, Bankruptcy, and Other Proceedings Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Litigation, Bankruptcy, and Other Proceedings Risk
Investments in stressed, distressed or bankrupt companies include a material risk of involving the Fund in a related litigation. Such litigation can be time consuming and expensive, and can frequently lead to unpredicted delays or losses. Litigation expenses, including payments pursuant to settlements or judgments, generally will be borne by the Fund. A bankruptcy filing may have adverse and permanent effects on a company. Further, if the proceeding is converted to a liquidation, the liquidation value of the company may not equal the liquidation value that was believed to exist at the time of the investment. In addition, a creditor’s return on investment can be impacted adversely by delays while a plan of reorganization is being negotiated, approved by the creditors, confirmed by the bankruptcy court (if applicable), and becomes effective. Certain fixed-income securities invested in by the Fund could be subject to U.S. federal, state or non-U.S. bankruptcy laws or fraudulent transfer or conveyance laws if such securities were issued with the intent of hindering, delaying or defrauding creditors or, in certain circumstances, if the issuer receives less than reasonably equivalent value or fair consideration in return for issuing such securities. If the Fund, the Manager or the sub-advisor were to be found to have interfered with the affairs of a company in which the Fund holds a debt investment, to the detriment of other creditors or common stockholders of such company, the Fund could be held liable for damages to injured parties or a bankruptcy court. Changes in bankruptcy laws (including U.S. federal and state laws and applicable non-U.S. laws) may adversely impact the Fund’s securities.

American Beacon DoubleLine Floating Rate Fund | Loan Interests Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

the allowable time periods stated in the Prospectus. The secondary market for loans also may be subject to irregular trading activity and wide bid/ask spreads. The lack of an active trading market for certain loans may impair the ability of the Fund to sell its loan interests at a time when it may otherwise be desirable to do so or may require the Fund to sell them at prices that are less than what the Fund regards as their fair market value and may make it difficult to value such loans. Accordingly, loan interests may at times be illiquid. Interests in loans made to finance highly leveraged companies or transactions, such as corporate acquisitions, may be especially vulnerable to adverse changes in economic or market conditions.

American Beacon DoubleLine Floating Rate Fund | Market Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

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

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

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

■

Recent Market Events Risk. Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. Moreover, during periods of significant volatility, the risks discussed herein associated with an investment in the Fund may be increased. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be changing, which may impact such economies and markets in ways that cannot be foreseen at this time.
Some countries, including the U.S., have adopted more protectionist trade policies, including trade tariffs and other trade barriers, which is a trend that appears to be continuing globally. The economies of all nations, including the U.S., are subject to the risks of slowing global economic growth, protectionist trade policies, inflationary pressures, limits imposed by international trade and security agreements, political or economic dysfunction, poor consumer sentiment, and reduced demand for goods due to fluctuating commodity prices and currency values, and these risks may create significant market volatility in ways that cannot be foreseen at the present time. These economic risks could have a negative impact on the Fund’s investments.
The U.S. Federal Reserve and certain foreign central banks have started to lower interest rates, though economic or other factors could stop or reverse such changes. It is difficult to accurately predict the various economic and political factors that influence the pace at which interest rates might change, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. Changes in interest rates could lead to an economic slowdown in the U.S. and abroad, significant market volatility and reduced liquidity in certain sectors of the market.
Tensions, war, or open conflict between nations, such as among the United States, Israel and Iran, between Russia and Ukraine, otherwise in the Middle East or in eastern Asia could affect the economies of many nations, including the United States and may contribute to increased volatility and uncertainty in the financial markets. The extent and duration of ongoing hostilities and related sanctions and the repercussions of such events cannot be predicted. Those events have presented and could continue to present material uncertainty and risk with respect to markets globally, including in the oil and gas markets and potentially other industries and sectors, and the performance of the Fund and its investments or operations could be negatively impacted.
Advancements in technology, including advanced development and increased regulation of artificial intelligence, may adversely impact market movements and liquidity. As artificial intelligence is used more widely, which can occur relatively rapidly, the profitability and growth of certain issuers and industries may be negatively impacted in ways that cannot be foreseen and could adversely impact issuer and market performance. As a consequence, the Fund’s holdings and its overall performance could be negatively impacted.
Global climate change may affect property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change in ways that cannot be foreseen. The impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences that may not be foreseen, may negatively impact certain issuers, industries and regions.

American Beacon DoubleLine Floating Rate Fund | Market Timing Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Market Timing Risk
The Fund is subject to the risk of market timing activities by investors due to the nature of the Fund’s investments, which requires the Fund, in certain instances, to fair value certain of its investments. Some investors may engage in frequent short-term trading in the Fund to take advantage of any price differentials that may be reflected in the net asset value (“NAV”) of the Fund’s shares. Frequent trading by Fund shareholders poses risks to other shareholders in the Fund, including (i) the dilution of the Fund’s NAV, (ii) an increase in the Fund’s expenses, and (iii) interference with the ability to execute efficient investment strategies.

American Beacon DoubleLine Floating Rate Fund | Mortgage-Backed and Mortgage-Related Securities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

■

Adjustable Rate Mortgages (“ARMs”) Risk. ARMs contain maximum and minimum rates beyond which the mortgage interest rate may not vary over the lifetime of the security. In addition, many ARMs provide for additional limitations on the maximum amount by which the mortgage interest rate may adjust for any single adjustment period. Alternatively, certain ARMs contain limitations on changes in the required monthly payment. In the event that a monthly payment is not sufficient to pay the interest accruing on an ARM, any excess interest is added to the principal balance of the mortgage loan, which is repaid through future monthly payments. If the monthly payment for such an instrument exceeds the sum of the interest accrued at the applicable mortgage interest rate and the principal payment required at such point to amortize the outstanding principal balance over the remaining term of the loan, the excess is used to reduce the then-outstanding principal balance of the ARM. In addition, certain ARMs may provide for an initial fixed, below-market or teaser interest rate. During this initial fixed-rate period, the payment due from the related mortgagor may be less than that of a traditional loan. However, after

the teaser rate expires, the monthly payment required to be made by the mortgagor may increase significantly when the interest rate on the mortgage loan adjusts. This increased burden on the mortgagor may increase the risk of delinquency or default on the mortgage loan and in turn, losses on the mortgage-backed security into which that loan has been bundled.

■

Collateralized Mortgage Obligation (“CMOs”) Risk. CMOs, including real estate mortgage investment conduits (“REMICs”), may offer a higher yield than U.S. government securities, but they may also be subject to greater price fluctuation and credit risk. In addition, CMOs typically will be issued in a variety of classes or series, which have different maturities and are retired in sequence. In the event of a default by an issuer of a CMO, there is no assurance that the collateral securing such CMO will be sufficient to pay principal and interest. It is possible that there will be limited opportunities for trading CMOs in the OTC market, the depth and liquidity of which will vary from time to time.

American Beacon DoubleLine Floating Rate Fund | Other Investment Companies Risk [Member]

Risk [Text Block]

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

■

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

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

Prepayment and extension risk is the risk that a bond or other fixed-income security or investment might, in the case of prepayment risk, be called or otherwise converted, prepaid or redeemed before maturity and, in the case of extension risk, that the investment might not be prepaid as expected. Due to a decline in interest rates or excess cash flow into the issuer, a debt security may be called or otherwise converted, prepaid or redeemed before maturity. If this occurs, no additional interest will be paid on the investment. The Fund may have to reinvest the proceeds in another investment at a lower rate, may not benefit from an increase in value that may result from declining interest rates, and may lose any premium it paid to acquire the security, any of which could result in a reduced yield to the Fund. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. Conversely, extension risk is the risk that a decrease in prepayments may, as a result of higher interest rates or other factors, result in the extension of a security’s effective maturity, increase the risk of default or delayed payment, heighten interest rate risk and increase the potential for a decline in an investment’s price. In addition, as a consequence of a decrease in prepayments, the amount of principal available to the Fund for investment would be reduced. Extensions of obligations could cause the Fund to exhibit additional volatility and hold securities paying lower-than-market rates of interest. Either case could hurt the Fund’s performance.

American Beacon DoubleLine Floating Rate Fund | Redemption Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Redemption Risk
The Fund may experience periods of high levels of redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. Heavy redemptions could hurt the Fund’s performance. The sale of assets to meet redemption requests may create net capital gains, which could cause the Fund to have to distribute substantial capital gains. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund. In addition, redemption risk is heightened during periods of declining or illiquid markets. A rise in interest rates or other market developments may cause investors to move out of fixed-income securities on a large scale. During periods of heavy redemptions, the Fund may borrow funds through the interfund credit facility or from a bank line of credit, which may increase costs.

Reliance on Corporate Management and Financial Reporting Risk
The sub-advisor may select investments for the Fund in part on the basis of information and data made directly available to the sub-advisor by the issuers of securities or through sources other than the issuers such as collateral pool servicers. The sub-advisor has no ability to independently verify such information and data and is therefore dependent upon the integrity of the management of these issuers and of such servicers and the financial and collateral performance reporting processes in general. Information and data provided regarding a particular issuer may not necessarily contain information that the sub-advisor normally considers when evaluating the investment prospects of a company.

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

Restricted Securities Risk
Securities not registered in the U.S. under the Securities Act of 1933, as amended (the “Securities Act”), or in non-U.S. markets pursuant to similar regulations, including “Section 4(a)(2)” securities and “Rule 144A” securities, are restricted as to their resale. Such securities may not be listed on an exchange and may have no active trading market. The prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. They may be more difficult to purchase or sell at an advantageous time or price because such securities may not be readily marketable in broad public markets or may have to be held for a certain time period before they can be resold. The Fund may not be able to sell a restricted security when the sub-advisor considers it desirable to do so and/or may have to sell the security at a lower price than the Fund believes is its fair market value. In addition, transaction costs may be higher for restricted securities and the Fund may receive only limited information regarding the issuer of a restricted security. The Fund may have to bear the expense of registering restricted securities for resale and the risk of substantial delays in effecting the registration.

American Beacon DoubleLine Floating Rate Fund | Secured, Partially Secured and Unsecured Obligation Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Secured, Partially Secured and Unsecured Obligation Risk
Debt obligations may be secured, partially secured or unsecured. Interests in secured and partially-secured obligations have the benefit of collateral and, typically, of restrictive covenants limiting the ability of the borrower to further encumber its assets. However, there is no assurance that the liquidation of collateral from a secured or partially-secured obligation would satisfy the borrower’s obligation, or that the collateral can be liquidated. Furthermore, there is a risk that the value of any collateral securing an obligation in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the obligation. In the event the borrower defaults, the Fund’s access to the collateral may be limited or delayed by bankruptcy or other insolvency laws. Unsecured debt, including senior unsecured and subordinated debt, will not be secured by any collateral and will be effectively subordinated

to a borrower’s secured indebtedness (to the extent of the collateral securing such indebtedness). With respect to unsecured obligations, the Fund lacks any collateral on which to foreclose to satisfy its claim in whole or in part. Such instruments generally have greater price volatility than that of fully secured holdings and may be less liquid.

Prospectus [Line Items]

Risk [Text Block]

Stressed, Distressed, and Defaulted Securities Risk
The Fund may invest in the debt securities of financially stressed or distressed issuers, including those that are in default or the issuers of which are in bankruptcy. Investments in the securities of financially stressed or distressed issuers are speculative and involve substantial risks. These securities may present a substantial risk of default or may be in default at the time of investment. In addition, these securities may fluctuate more in price, and are typically less liquid than other higher-rated debt securities. 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. The Fund is also subject to significant uncertainty as to when, and in what manner, and for what value obligations evidenced by securities of financially stressed or distressed issuers will eventually be satisfied (e.g., through a liquidation of the issuer’s assets, an exchange offer or plan of reorganization, or a payment of some amount in satisfaction of the obligation). Defaulted obligations might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments. In any such proceeding relating to a defaulted obligation, the Fund may lose its entire investment or may be required to accept cash or securities with a value substantially 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.

The level of analytical sophistication, both financial and legal, necessary for successful investment in stressed or distressed assets is particularly high. There is no assurance that the Fund will correctly evaluate the value of the assets collateralizing the Fund’s investments or the prospects for a successful reorganization or similar action in respect of any company. In any reorganization or liquidation proceeding relating to a company in which the Fund invests, the Fund may lose its entire investment, may be required to accept cash or securities with a value less than the Fund’s original investment and/or may be required to accept payment over an extended period of time.

Risk [Text Block]

Structured Products and Structured Notes Risk
The risk that an investment in a structured product, which includes, among other things, collateralized debt obligations, mortgage-backed securities, other types of asset-backed securities and certain types of structured notes, may decline in value due to changes in the underlying instruments, indexes, interest rates or other factors on which the product is based (“reference measure”). Depending on the reference measure used and the use of multipliers or deflators (if any), changes in interest rates and movement of the reference measure may cause significant price and cash flow fluctuations. Application of a multiplier is comparable to the use of financial leverage, a speculative technique. Holders of structured products indirectly bear risks associated with the reference measure, are subject to counterparty risk and typically do not have direct rights against the reference measure. Structured products are generally privately offered and sold, and thus, are not registered under the securities laws and may be thinly traded or have a limited trading market and may have the effect of increasing the Fund’s illiquidity, reducing the Fund’s income and the value of the investment. At a particular point in time, the Fund may be unable to find qualified buyers for these securities. Investments in structured notes involve risks including interest rate risk, credit risk and market risk.

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

U.S. Government Securities and Government-Sponsored Enterprises Risk
A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of coupons and the face value at maturity, not its current market price. The market prices for such securities are not guaranteed and will fluctuate. Certain securities held by the Fund that are issued by government-sponsored enterprises, such as the Federal National Mortgage Association (‘‘Fannie Mae’’), Federal Home Loan Mortgage Corporation (‘‘Freddie Mac’’), Federal Home Loan Bank (‘‘FHLB’’), and Federal Farm Credit Bank (“FFCB”), are not guaranteed by the U.S. Treasury and are not backed by the full faith and credit of the U.S. government, and no assurance can be given that the U.S. government will provide financial support if these organizations do not have the funds to meet future payment obligations. U.S. government securities and securities of government-sponsored enterprises are also subject to credit risk, interest rate risk and market risk. The rising U.S. national debt may lead to adverse impacts on the value of U.S. government securities due to potentially higher costs for the U.S. government to obtain new financing. It is possible that the U.S. government and government-sponsored enterprises will not have the funds to meet their payment obligations in the future.

The valuation of the Fund’s investments in an accurate and timely manner may be impacted by technological issues and/or errors by third party service providers, such as pricing services or accounting agents.

American Beacon DoubleLine Floating Rate Fund | Variable and Floating Rate Securities Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

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

Equipment Trust Certificates (“ETCs”) and Enhanced Equipment Trust Certificates (“EETCs”) Risk. ETCs and EETCs are types of asset-backed securities that generally represent undivided fractional interests in a trust whose assets consist of a pool of equipment retail installment contracts or leased equipment. EETCs are similar to ETCs, except that the securities have been divided into two or more classes, each with different payment priorities and asset claims. ETCs and EETCs are typically issued by specially-created trusts established by airlines, railroads, or other transportation firms. The assets of ETCs and EETCs are used to purchase equipment, such as airplanes, railroad cars, or other equipment, which may in turn serve as collateral for the related issue of the ETCs or EETCs, and the title to such equipment is held in trust for the holders of the issue. The equipment generally is leased from the specially-created trust by the airline, railroad or other firm, which makes rental or lease payments to the specially-created trust to provide cash flow for payments to ETC and EETC holders. Holders of ETCs and EETCs must look to the collateral securing the certificates, typically together with a guarantee provided by the lessee firm or its parent company for the payment of lease obligations, in the case of default in the payment of principal and interest on the ETCs or EETCs. ETCs and EETCs are subject to the risk that the lessee or payee defaults on its payments, and risks related to potential declines in the value of the equipment that serves as collateral for the issue. ETCs and EETCs are generally regarded as obligations of the company that is leasing the equipment and may be shown as liabilities in its balance sheet as a capitalized lease in accordance with generally accepted accounting principles. The lessee company, however, does not own the equipment until all the certificates are redeemed and paid. In the event the company defaults under its lease, the trustee may terminate the lease. If another lessee is not available, then payments on the certificates would cease until another lessee is available.

American Beacon DoubleLine Select Income Fund | Interest Rate Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Interest Rate Risk
Generally, the value of investments with interest rate risk, such as fixed-income securities, will move in the opposite direction as movements in interest rates. Factors including central bank monetary policy, rising inflation rates, and changes in general economic conditions may cause interest rates to rise, which could cause the value of the Fund’s investments to decline. Interest rate increases, including significant or rapid increases, may result in a decline in the value of bonds held by the Fund, make issuers less willing or able to make principal and interest payments on fixed-income investments when due, lead to heightened volatility in the fixed-income markets and adversely affect the liquidity of certain fixed-income investments, any of which may result in substantial losses to the Fund. When interest rates decline, issuers may prepay higher-yielding securities held by the Fund, resulting in the Fund reinvesting in securities with lower yields, which may cause a decline in its income. Interest rate changes may have a more pronounced effect on the market value of fixed-rate instruments than on floating-rate instruments. The value of floating rate and variable securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The prices of fixed-income securities are also affected by their durations. Fixed-income securities with longer durations generally have greater sensitivity to changes in interest rates than those with shorter durations. Rising interest rates may cause the value of the Fund’s investments with longer durations and terms to maturity to decline, which may adversely affect the value of the Fund. For example, if a bond has a duration of three years, a 1% increase in interest rates could be expected to result in a 3% decrease in the value of the bond. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund.

American Beacon DoubleLine Select Income Fund | Loan Interests Risk [Member]

Prospectus [Line Items]

Risk [Text Block]

Unlike publicly traded common stocks, which trade on national exchanges, there is no central place or exchange for loans, including bank loans and senior loans, to trade. There is a risk that the value of any collateral securing a loan in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. In the event that the borrower defaults, the Fund’s access to the collateral may be limited or delayed by bankruptcy or other insolvency laws. Loans trade in an over-the-counter market, and confirmation and settlement, which are effected through standardized procedures and documentation, may take significantly longer than seven days to complete. Extended trade settlement periods may, in unusual market conditions with a high volume of shareholder redemptions, present a risk to shareholders with respect to the Fund’s ability to pay redemption proceeds within the allowable time periods stated in the Prospectus. The secondary market for loans also may be subject to irregular trading activity and wide bid/ask spreads. The lack of an active trading market for certain loans may impair the ability of the Fund to sell its loan interests at a time when it may otherwise be desirable to do so or may require the Fund to sell them at prices that are less than what the Fund regards as their fair market value and may make it difficult to value such loans. Accordingly, loan interests may at times be illiquid. Interests in loans made to finance highly leveraged companies or transactions, such as corporate acquisitions, may be especially vulnerable to adverse changes in economic or market conditions.

Derivatives Risk
Derivatives may involve significant risk. The use of derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities or other instruments underlying those derivatives, including the high degree of leverage often embedded in such instruments, and potential material and prolonged deviations between the theoretical value and realizable value of a derivative. The use of derivatives may also increase any adverse effects resulting from the underperformance of strategies, asset classes and market exposures to which the Fund has allocated its assets. Derivatives may at times be highly illiquid, and the Fund may not be able to close out or sell a derivative at a particular time or at an anticipated price. Certain derivatives may be difficult to value, and valuation may be more difficult in times of market turmoil. Derivatives may also be more volatile than other types of investments. Derivative investments can increase portfolio turnover and transaction costs. Derivatives also are subject to counterparty risk and credit risk. As a result, the Fund may not recover its investment or may only obtain a limited recovery, and any recovery may be delayed. 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 transactions requiring the Fund to post collateral may expose the Fund to greater losses in the event of a default by a counterparty. There may be imperfect correlation between the behavior of a derivative and that of the reference instrument underlying the derivative. An abrupt change in the price of a reference instrument could render a derivative worthless. Derivatives may involve risks different from, and possibly greater than, the risks associated with investing directly in the reference instrument. The Fund may buy or sell derivatives not traded on an exchange, which may be subject to heightened counterparty, liquidity and valuation risks. Suitable derivatives may not be available in all circumstances, and there can be no assurance that the Fund will use derivatives to reduce exposure to other risks when that might have been beneficial. Ongoing changes to the regulation of derivatives and changes in the regulation of funds using derivative instruments could limit the Fund’s ability to pursue its investment strategies. New regulation of derivatives may make them more costly, or may otherwise adversely affect their liquidity, value or performance. In addition, the Fund’s investments in derivatives are subject to the following risks:

■

Futures Contracts Risk. Futures contracts are derivative instruments pursuant to a contract where the parties agree to a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks, such as liquidity risk and counterparty risk, that it would not be subject to if it invested directly in the securities underlying those derivatives. There can be no assurance that any strategy used will succeed. There may at times be an imperfect correlation between the movement in the prices of futures contracts and the value of their underlying instruments or indexes. There also can be no assurance that, at all times, a liquid market will exist for offsetting a futures contract that the Fund has previously bought or sold, and this may result in the inability to close a futures contract when desired. Futures contracts may experience potentially dramatic price changes, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract). The Fund may invest in the following types of futures contracts:

•

Interest Rate Futures Contracts Risk. Interest rate futures contracts expose the Fund to price fluctuations resulting from changes in interest rates. The Fund could suffer a loss if interest rates rise after the Fund has purchased an interest rate futures contract or fall after the Fund has sold an interest rate futures contract.

•	Treasury Futures Contracts Risk. Treasury futures contracts expose the Fund to price fluctuations resulting from changes in interest rates and to potential losses if interest rates do not move as expected.

■

Structured Notes Risk. Structured notes are derivative debt instruments with principal and/or interest payments linked to the value of a commodity, a foreign currency, an index of securities, an interest rate, or other financial indicators (“reference instruments”). The payments on a structured note may vary based on changes in one or more specified reference instruments, such as a floating interest rate compared to a fixed interest rate, the exchange rates between two currencies, one or more securities or a securities or commodities index. If the underlying investment or index does not perform as anticipated, the structured note might pay less interest than the stated coupon payment or repay less principal upon maturity. The movement of such factors may cause significant price fluctuations. A structured note may be positively or negatively indexed. Structured notes are subject to interest rate risk, market risk, liquidity risk and counterparty risk. They are also subject to credit risk with respect both to the issuer and, if applicable, to the underlying security or borrower. Structured notes may have a limited trading market, making it difficult to value them or sell them at an acceptable price.

Electric Utilities and Power: utility- and power-related infrastructure assets may have difficulty obtaining financing during periods of inflation or unsettled capital markets; may be subject to greater competition as a result of deregulation; face changes in climate or environmental policy; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters.

■

Energy: energy-related infrastructure assets may be adversely affected by one or more of the following: the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production of energy sources, energy conservation efforts, exchange rates, interest rates, economic conditions, tax treatment, increased competition, government regulation, technological advances, risk of liability from accidents resulting in injury or loss of life or property, supply of products and services, and world events.

■

Renewable Energy: renewable-energy related infrastructure assets may be adversely affected by changes in government policy relating to incentives and subsidies for renewable energy assets, technological developments (or the application thereof), unforeseen technical deficiencies with installations, and the reliance of any renewable energy project, or group of projects, on variable resources.

■

Communication Networks and Equipment: infrastructure assets in the telecommunications sector may be adversely affected by increased competition, regulation by various regulatory authorities, distressed cash flows due to the need to commit substantial capital to meet increasing competition, technological advances, limited availability of franchise and licensing rights, and high barriers to market entry. Various forms of cyber attack threaten communication networks and could severely hamper any infrastructure project dependent upon communication networks and equipment.

■

Public and Social Infrastructure: public and social infrastructure assets, such as hospitals, schools, government accommodations, and other public service facilities projects, may be subject to risks that include, but are not limited to, costs associated with governmental, environmental and other regulations, the effects of economic slowdowns, increased competition from other providers of such services, uncertainties concerning costs, adverse political developments, and the level of government spending on infrastructure projects.

■

Metals and Mining: investments in metals and mining related infrastructure assets may be speculative and subject to greater price volatility than investments in other types of companies. The performance of assets in this sector is related to, among other things, worldwide metal prices, and extraction and production costs.

■

Industrial: industrial-related infrastructure assets may be adversely affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, changes or trends in commodity prices, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these assets and their ability to repay their debts.

Model and Data Risk
Models and data are used to screen potential investments for the Fund. When models or data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Some of the models used by the sub-advisor are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. There is no assurance that the models are complete, accurate, or representative of future market cycles, nor will they always be beneficial to the Fund if they are accurate. Additionally, programs may become outdated or experience malfunctions which may not be identified by the sub-advisor and therefore may also result in losses to the Fund. These models may negatively affect Fund performance for various other reasons, including human judgment, inaccuracy of historical data and non-quantitative factors (such as market or trading system dysfunctions, investor fear or overreaction). The use of artificial intelligence or other evolving or emerging technologies presents significant risks and may exacerbate the aforementioned risks.

Municipal Securities Risk
Municipal securities could be affected by adverse political and legislative changes. The ability of a municipal issuer to make payments can be affected by uncertainties in the municipal securities market, including: litigation; the strength of the local or national economy; the issuer’s ability to raise revenues through tax or other means; budgetary constraints of local, state and federal governments upon which the issuer may be relying for funding; a legislature’s willingness or ability to appropriate funds needed to pay municipal securities obligations; the bankruptcy of the issuer; adverse political and legislative changes, including to eliminate or limit the tax-exempt status of municipal bond interest or dividends; and other changes in the financial condition of a municipality. At times, municipal issuers have defaulted on obligations or commenced insolvency proceedings. Financial difficulties of municipal issuers may continue or get worse in the future. Reductions in tax rates may make municipal securities less attractive in comparison to taxable bonds.

Sovereign and Quasi-Sovereign Debt Risk
Sovereign or quasi-sovereign debt securities are subject to risk of payment delays or defaults due to, among other things: (1) country cash flow problems, (2) insufficient foreign currency reserves, (3) political considerations, (4) large debt positions relative to the country’s economy, (5) policies toward foreign lenders or investors, (6) the failure to implement economic reforms required by the International Monetary Fund or other multilateral agencies, or (7) an inability or unwillingness to repay debts. It may be particularly difficult to enforce the rights of debt holders in emerging markets. A governmental entity that defaults on an obligation may request additional time in which to repay loans, may request further loans, or may seek to restructure its obligations to reduce interest rates or outstanding principal. There is no legal process for collecting sovereign and quasi-sovereign debt that a government does not pay, nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected. Sovereign and quasi-sovereign debt risk is increased for emerging markets issuers, which are among the largest debtors to commercial banks and foreign governments. At times, certain emerging market countries have declared moratoria on the payment of principal and interest on external debt. Certain emerging market countries have experienced difficulty in servicing their sovereign debt on a timely basis, which has led to defaults and the restructuring of certain indebtedness.

Supranational Risk
Obligations of supranational entities are subject to the risk that the governments on whose support the entity depends for its financial backing or repayment may be unable or unwilling to provide that support. Political changes in principal donor nations may also unexpectedly disrupt the finances of supranational entities. Obligations of a supranational entity that are denominated in non-U.S. currencies will also be subject to the risks associated with investments in non-U.S. currencies.
