The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 28% of the average value of its portfolio.

Under normal circumstances, between 50% and 70% of the Fund's total assets are invested in equity securities and between 30% and 50% of the Fund's total assets are invested in debt securities.

The Fund's equity investments may include common stocks, real estate investment trusts ("REITs"), American Depositary Receipts ("ADRs") and U.S. dollar-denominated foreign stocks traded on U.S. exchanges (collectively referred to as "stocks"). The Fund may invest in companies of all market capitalizations. The Manager allocates the assets of the Fund among different sub-advisors.

The Manager believes that this strategy may help the Fund outperform other investment styles over the longer term while reducing volatility and downside risk.

The Fund's sub-advisors select stocks that, in their opinion, have most or all of the following characteristics (relative to the S&P 500® Index):

above-average earnings growth potential,
below-average price to earnings ratio,
below-average price to book value ratio, and
above-average dividend yields.

Each of the Fund's sub-advisors determines the earnings growth prospects of companies based upon a combination of internal and external research using fundamental analysis and considering changing economic trends. The sub-advisors typically seek to invest in companies that they believe to be undervalued at the time of purchase. The decision to sell a stock is typically based on the belief that the company is no longer considered undervalued or shows deteriorating fundamentals, or that better investment opportunities exist in other stocks. The Fund's debt securities may include: obligations of the U.S. Government, its agencies and instrumentalities, including U.S. Government-sponsored enterprises (some of which are not backed by the full faith and credit of the U.S. Government); U.S. and U.S. dollar-denominated foreign corporate debt securities, such as notes and bonds, mortgage-backed securities; and asset-backed securities.

The Fund will only buy debt securities that are deemed by the Manager or sub-advisors, as applicable, to be investment grade at the time of the purchase. If an investment held by the Fund is downgraded below investment grade, the Manager or sub-advisors, as applicable will take action that they believe to be advantageous to the Fund. The Fund has no limitations regarding the duration of the debt securities it can buy. The Fund may have significant exposure to the Financial Services sector. However, as the sector composition of the Fund's portfolio changes over time, the Fund's exposure to the Financial Services sector may be lower at a future date, and the Fund's exposure to other market sectors may be higher.

In determining which debt securities to buy and sell, the Manager and the sub-advisors generally use a "top-down" or "bottom-up" investment strategy, or a combination of both strategies. The top-down fixed-income investment strategy is implemented as follows:

Develop an overall investment strategy, including a portfolio duration target, by examining the current trends in the U.S. economy.
Set desired portfolio duration structure by comparing the differences between corporate and U.S. Government securities of similar duration to judge their potential for optimal return in accordance with the target duration benchmark.
Determine the weightings of each security type by analyzing the difference in yield spreads between corporate and U.S. Government securities.
Select specific debt securities within each security type.
Review and monitor portfolio composition for changes in credit, risk-return profile and comparisons with benchmarks.

The bottom-up fixed-income investment strategy is implemented as follows:

Search for eligible securities with a yield to maturity advantage versus a U.S. Government security with a similar duration.
Evaluate credit quality of the securities.
Perform an analysis of the expected price volatility of the securities to changes in interest rates by examining actual price volatility between U.S. Government and non-U.S. Government securities.

The Fund may invest cash balances in other investment companies, including money market funds, and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs. The Fund may seek to earn additional income by lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis.

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of current income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund, which are described in alphabetical order and not in order of importance or potential exposure, are:

Allocation Risk
The Manager's and the sub-advisors' judgments about, and allocations among, asset classes and market exposures may adversely affect the Fund's performance. This risk may be increased by the use of derivatives to increase allocations to various market exposures.

Asset-Backed and Mortgage Related Securities Risk
Investments in asset-backed and mortgage related securities are subject to market risks for fixed-income securities which include, but are not limited to, credit risk, extension risk, interest rate risk and prepayment risk. A decline in the credit quality of the issuers of asset-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.

Credit Risk
The Fund is subject to the risk that the issuer or guarantor of a debt security, or the counterparty to a futures contract or a loan will fail to make timely payment of interest or principal or otherwise honor its obligations or default completely.

Cybersecurity and Operational Risk
The Fund and its service providers, and shareholders' ability to transact with the Fund, may be negatively impacted due to operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. 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. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Equity Investments Risk
Equity securities are subject to investment and market risk. The Fund's investments in equity securities may include common stocks, REITs, depositary receipts, and U.S. dollar-denominated foreign stocks traded on U.S. exchanges. Such investments may expose the Fund to additional risks.

Common Stock. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.
Depositary Receipts. Depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency exchange rate fluctuations, political and financial instability in the home country of a particular depositary receipt or foreign stock, less liquidity and more volatility, less government regulation and supervision and delays in transaction settlement.
REITs. Investments in REITs are subject to the risks associated with investing in the real estate industry such as adverse developments affecting the real estate industry and real property values. REITs also are dependent upon the skills of their managers and are subject to heavy cash flow dependency or self-liquidation. Domestic REITs could be adversely affected by failure to qualify for tax-free "pass-through" of distributed net income and net realized gains under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. REITs typically incur fees that are separate from those incurred by the Fund. Accordingly, the Fund's investment in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs' operating expenses, in addition to paying Fund expenses. The value of REIT common stock may decline when interest rates rise.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks 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 and financial reporting standards, (5) increased volatility, (6) less government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays in transaction settlement in some foreign markets.

Futures Contracts Risk
Futures contracts are derivative instruments 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 that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience potentially dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index, 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).

Interest Rate Risk
The Fund is subject to the risk that the market value of fixed-income securities it holds will decline due to rising interest rates. Generally, the value of investments with interest rate risk, such as fixed-income securities, will move in the opposite direction to movements in interest rates. The Federal Reserve has raised the federal funds rate several times since December 2015 and may continue to increase rates in the future. Interest rates may rise, perhaps significantly and/or rapidly, potentially resulting in substantial losses to the Fund. The prices of fixed-income securities are also affected by their durations. Fixed income securities with longer duration generally have greater sensitivity to changes in interest rates. An increase in interest rates can impact markets broadly as well.

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

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

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

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund, such as certain fixed income instruments, may have limited marketability or be subject to restrictions on sale, and may be difficult or impossible to purchase or sell at favorable times or prices. Market prices for such instruments may be volatile. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund. For example, liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Unexpected redemptions may force the Fund to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

Market Risk
In recent periods, fixed income instruments have experienced unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. These events have reduced the willingness and ability of some lenders to extend credit, and have made it more difficult for some borrowers to obtain financing on attractive terms, if at all. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

In addition, political and governmental events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. Because the impact on the markets has been widespread, it may be difficult to identify both risks and opportunities using past models of the interplay of market forces, or to predict the duration of these market conditions. Interest rates have been unusually low in recent years in the U.S. and abroad. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase, whether brought about by U.S. policy makers or by dislocations in world markets. In addition, there is a risk that the prices of goods and services in the U.S. and many foreign economies may decline over time, known as deflation (the opposite of inflation). Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely.

Multiple Sub-Advisor Risk
The Manager may allocate the Fund's assets among multiple sub-advisors, each of which is responsible for investing its allocated portion of the Fund's assets. To a significant extent, the Fund's performance will depend on the success of the Manager in allocating the Fund's assets to sub-advisors and its selection and oversight of the sub-advisors.

Other Investment Companies Risk
The Fund may invest in shares of other registered investment companies, including money market funds. 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 and will be subject to the risks associated with investments in those companies. For example, money market funds are subject to interest rate risk, credit risk, and market risk.

Prepayment and Extension Risk
Prepayment risk is the risk that the principal amount of a bond may be repaid prior to the bond's maturity date. Due to a decline in interest rates or excess cash flow, a debt security may be called or otherwise prepaid before maturity. If this occurs, no additional interest will be paid on the investment and the Fund may have to invest 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. Variable and floating rate securities may be less sensitive to prepayment risk. 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, heighten interest rate risk and increase the potential for a decline in its price.

Redemption Risk
Due to a rise in interest rates or other market developments that may cause investors to move out of fixed income securities on a large scale, 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. 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 heightened during periods of declining or illiquid markets. Heavy redemptions could hurt the Fund's performance.

Sector Risk
When the Fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the Fund were invested more evenly across sectors.

Financial Services Sector Risk. To the extent the Fund invests in the financial services sector, the value of the Fund's shares may be particularly vulnerable to factors affecting that sector, such as the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, extensive government regulation and price competition.

Securities Lending Risk
To the extent the Fund lends its securities, it may be subject to the following risks: i) borrowers of the Fund's securities typically provide collateral in the form of cash that is reinvested in securities, ii) the securities in which the collateral is invested may not perform sufficiently to cover the return collateral payments owed to borrowers, iii) delays may occur in the recovery of securities from borrowers, which could interfere with the Fund's ability to vote proxies or to settle transactions, and iv) there is the risk of possible loss of rights in the collateral should the borrower fail financially.

Securities Selection Risk
Securities selected by the sub-advisors or the Manager for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objectives.

Segregated Assets Risk
In connection with certain transactions that may give rise to future payment obligations, including the purchase and sale of futures contracts, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the obligation. Segregated assets cannot be sold while the position they are covering is outstanding, unless they are replaced with other assets of equal value. The need to maintain cash or other liquid securities in segregated accounts could limit the Fund's ability to pursue other opportunities as they arise.

Small and Mid-Capitalization Companies Risk
Investing in the securities of small and mid-capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies. Since small and mid-capitalization companies may have narrower commercial markets and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity, and they can be particularly sensitive to expected changes in interest rates, borrowing costs and earnings. In general, these risks are greater for small-capitalization companies than for mid-capitalization companies.

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 interest and principal when held to maturity. The market prices for such securities are not guaranteed and will fluctuate. 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''), Federal Farm Credit Bank ("FFCB"), and the Tennessee Valley Authority 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 entities are also subject to credit risk, interest rate risk and market risk.

Value Stocks Risk
Value stocks are subject to the risk that their intrinsic value may never be realized by the market or that their prices may decline. The Fund's investments in value stocks seek to limit potential downside price risk over time; however, value stock prices still may decline substantially. In addition, the Fund may produce more modest gains as a trade-off for this potentially lower risk. The Fund's investment in value stocks could cause the Fund to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

The bar chart and table below provide an indication of risk by showing how the Fund's performance has varied from year to year. The table shows how the Fund's performance compares to a composite index and the two broad-based securities market indices that comprise the composite index.

The chart and the table show the performance of the Fund's Investor Class shares for all periods. The Fund began offering Institutional Class Shares on July 17, 1987, Investor Class shares on August 1, 1994, Advisor Class shares on May 31, 2005, Y Class shares on March 1, 2010, A Class shares on May 17, 2010 and C Class shares on September 1, 2010. In the table below, the performance of the Institutional Class shares is shown for the Y Class shares and the performance of the Investor Class shares is shown for the A Class and C Class shares, prior to the dates such newer classes were first offered. In each case, the older share classes would have had similar annual returns to the newer share classes because the shares are invested in the same portfolio securities. However, the older share classes had different expenses than the newer share classes. You may obtain updated performance information on the Fund's website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

<div style="font-size:10pt;padding-top:5pt;padding-bottom:0;padding-left:0;"> <b>Average annual total returns for periods ended December 31, 2018</b></div>

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local income taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. If you are a tax-exempt entity or hold your Fund shares through a tax-deferred arrangement, such as an individual retirement account ("IRA") or a 401(k) plan, the after-tax returns do not apply to your situation. After-tax returns are shown only for Investor Class shares; after-tax returns for other share classes will vary.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 143% of the average value of its portfolio.

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

The types of investment grade debt securities that the Fund primarily invests in include obligations of the U.S. Government, its agencies and instrumentalities, including U.S. Government-sponsored enterprises (some of which are not backed by the full faith and credit of the U.S. Government); floating rate debt securities, corporate bonds, debentures, and mortgage-backed securities. These types of obligations are also commonly referred to as fixed-income securities or bonds. If an investment held by the Fund is downgraded below investment grade, the sub-advisor will determine whether to continue to hold or to sell the security. In selecting investment grade debt securities within the corporate sector, the sub-advisor first screens for the largest issuers and companies rated A- or better by at least two rating agencies and then eliminates foreign companies, Yankee Bonds and alcohol, tobacco, gambling, and defense companies and other sustainable investing violators. The risk/reward profile of these securities are not warranted exposure for the Fund. The sub-advisor considers environmental, social, and governance ("ESG") indicators as an integrated part of the research and investment process.

Under normal circumstances, the Fund seeks to maintain a weighted average duration of zero to seven years. Duration is an indicator of a bond's price sensitivity to a change in interest rates. For example, a duration of seven years means that a security's price would be expected to decrease by approximately 7% with a 1% increase in interest rates. The Fund may invest in securities of any maturity, but typically invests in securities with maximum maturities of up to 30 years.

The sub-advisor follows a fixed-income investment strategy that focuses on high current income and the preservation of capital. In selecting securities for the Fund, the sub-advisor employs a top-down approach, which includes a broad fundamental analysis of the current fixed-income markets, including duration, the yield curve, and the performance of market sectors. Through this analysis, the sub-advisor creates defined parameters for the selection of investments for the Fund's portfolio. The sub-advisor selects investments for the Fund by using a proprietary investment process comprised of qualitative and quantitative components. The Fund may have significant exposure to the Financial Services sector. However, as the sector composition of the Fund's portfolio changes over time, the Fund's exposure to the Financial Services sector may be lower at a future date, and the Fund's exposure to other market sectors may be higher.

The Fund may invest cash balances in other investment companies, including money market funds, to reduce market exposure or in anticipation of liquidity needs.

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund, which are described in alphabetical order and not in order of importance or potential exposure, are:

Credit Risk
The Fund is subject to the risk that the issuer or guarantor of a debt security, or counterparty to a loan, will fail to make timely payment of interest or principal, or otherwise honor its obligations or default completely.

Cybersecurity and Operational Risk
The Fund and its service providers, and shareholders' ability to transact with the Fund, may be negatively impacted due to operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. 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. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Floating Rate Securities Risk
The coupons on floating rate securities are not fixed and may fluctuate based upon changes in market rates. The coupon on a floating rate security is generally based on an interest rate such as a money-market index, London Interbank Offered Rate ("LIBOR") or a Treasury bill rate. Floating rate securities are subject to interest rate risk and credit risk.

As short-term interest rates decline, the coupons on floating rate securities typically decrease. Alternatively, during periods of rising interest rates, the coupons on floating-rate securities typically increase. Changes in the coupons of 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 floating rate securities may decline if their coupons do not rise as much, or as quickly, as interest rates in general. Floating rate securities will not generally increase in value if interest rates decline.

High Portfolio Turnover Risk
Portfolio turnover is a measure of the Fund's trading activity over a one-year 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 could increase the Fund's transaction costs and possibly have a negative impact on performance.

Interest Rate Risk
The Fund is subject to the risk that the market value of fixed-income securities it holds will decline due to rising interest rates. Generally, the value of investments with interest rate risk, such as fixed-income securities, will move in the opposite direction to movements in interest rates. The Federal Reserve has raised the federal funds rate several times since December 2015 and may continue to increase rates in the future. Interest rates may rise, perhaps significantly and/or rapidly, potentially resulting in substantial losses to the Fund. The prices of fixed-income securities are also affected by their durations. Fixed income securities with longer duration generally have greater sensitivity to changes in interest rates. An increase in interest rates can impact markets broadly as well.

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

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

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may have limited marketability or be subject to restrictions on sale, and may be difficult or impossible to purchase or sell at favorable times or prices. Market prices for such instruments may be volatile. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund. For example, liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Unexpected redemptions may force the Fund to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

Market Risk
In recent periods, fixed income instruments have experienced unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. These events have reduced the willingness and ability of some lenders to extend credit, and have made it more difficult for some borrowers to obtain financing on attractive terms, if at all. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

In addition, political and governmental events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. Because the impact on the markets has been widespread, it may be difficult to identify both risks and opportunities using past models of the interplay of market forces, or to predict the duration of these market conditions. Interest rates have been unusually low in recent years in the U.S. and abroad. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase, whether brought about by U.S. policy makers or by dislocations in world markets. In addition, there is a risk that the prices of goods and services in the U.S. and many foreign economies may decline over time, known as deflation (the opposite of inflation). Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely.

Mortgage-Backed and Mortgage-Related Securities Risk
Investments in mortgage-backed and mortgage-related securities are subject to market risks for fixed-income securities which include, but are not limited to, interest rate risk, credit risk, extension risk and prepayment risk. A decline in the credit quality of 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.

Other Investment Companies Risk
The Fund may invest in shares of other registered investment companies, including money market funds. 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 and will be subject to the risks associated with investments in those companies. For example, money market funds are subject to interest rate risk, credit risk, and market risk.

Prepayment and Extension Risk
Prepayment risk is the risk that the principal amount of a bond may be repaid prior to the bond's maturity date. Due to a decline in interest rates or excess cash flow, a debt security may be called or otherwise prepaid before maturity. If this occurs, no additional interest will be paid on the investment and the Fund may have to invest 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. Variable and floating rate securities may be less sensitive to prepayment risk. 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, heighten interest rate risk and increase the potential for a decline in its price.

Redemption Risk
Due to a rise in interest rates or other market developments that may cause investors to move out of fixed income securities on a large scale, 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. 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 heightened during periods of declining or illiquid markets. Heavy redemptions could hurt the Fund's performance.

Sector Risk
When the Fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the Fund were invested more evenly across sectors.

Financial Services Sector Risk. To the extent the Fund invests in the financial services sector, the value of the Fund's shares may be particularly vulnerable to factors affecting that sector, such as the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, extensive government regulation and price competition.

Securities Selection Risk
Securities selected by the Sub-Advisor or the Manager for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objectives.

Socially Responsible Investing
The Fund's incorporation of environmental, social and/or governance considerations in its investment strategy may cause it to make different investments than funds that have a similar investment style but do not incorporate such considerations in their strategy. The Fund may not be able to take advantage of certain investment opportunities due to these considerations, which may adversely affect investment performance.

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. 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 interest and principal when held to maturity. The market prices for such securities are not guaranteed and will fluctuate. 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''), Federal Farm Credit Bank ("FFCB"), and the Tennessee Valley Authority 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 entities are also subject to credit risk, interest rate risk and market risk.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local income taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 29% of the average value of its portfolio.

Under normal circumstances, at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes) are invested in common stocks and securities convertible into common stocks (collectively, "stocks") of issuers based in at least three different countries located outside the United States. The Fund will primarily invest in countries comprising the Morgan Stanley Capital International® Europe Australasia and Far East Index ("MSCI EAFE Index"). The MSCI EAFE Index is comprised of equity securities of companies from various industrial sectors whose primary trading markets are located outside the United States. Companies included in the MSCI EAFE Index are selected from among the larger capitalization companies in these markets. The Fund may invest in companies of all market capitalizations. The Fund may use futures contracts and foreign currency forward contracts, including non-deliverable forward contracts ("NDFs"), as a hedge against foreign currency fluctuations.

The Manager allocates the assets of the Fund among different sub-advisors. The Manager believes that this strategy may help the Fund outperform other investment styles over the longer term while reducing volatility and downside risk.

The sub-advisors select stocks that, in their opinion, have most or all of the following characteristics (relative to that stock's country, sector or industry):

above-average return on equity or earnings growth potential,
below-average price to earnings or price to cash flow ratio,
below-average price to book value ratio, and
above-average dividend yields.

The sub-advisors may consider potential changes in currency exchange rates when choosing stocks. Each of the sub-advisors determines the earnings growth prospects of companies based upon a combination of internal and external research using fundamental analysis and considering changing economic trends. The decision to sell a stock is typically based on the belief that the company is no longer considered undervalued or shows deteriorating fundamentals, or that better investment opportunities exist in other stocks. A sub-advisor may trade forward foreign currency contracts, including NDFs, or currency futures in an attempt to reduce the Fund's risk exposure to adverse fluctuations in currency exchange rates.

The Fund may invest cash balances in other investment companies, including money market funds, and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs. The Fund may lend its securities to broker-dealers and other institutions to earn additional income.

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund, which are described in alphabetical order and not in order of importance or potential exposure, are:

Allocation Risk
The Manager's and the sub-advisors' judgments about, and allocations among, asset classes and market exposures may adversely affect the Fund's performance. This risk may be increased by the use of derivatives to increase allocations to various market exposures.

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

Credit Risk
The Fund is subject to the risk that the issuer or guarantor of a debt security, or the counterparty to a derivatives contract will fail to make timely payment of interest or principal or otherwise honor its obligations or default completely.

Currency Risk
The Fund may have exposure to foreign currencies by making direct investments in non-U.S. currencies or in securities denominated in non-U.S. currencies, purchasing or selling forward currency exchange contracts in non-U.S. currencies, and non-U.S. currency futures contracts. Foreign currencies will fluctuate, and may decline in value relative to the U.S. dollar and other currencies and thereby affect the Fund's investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, or in derivatives that provide exposure to, foreign (non-U.S.) currencies. Not all forward contracts require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty.

Cybersecurity and Operational Risk
The Fund and its service providers, and shareholders' ability to transact with the Fund, may be negatively impacted due to operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. 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. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Equity Investments Risk
Equity securities are subject to investment and market risk. The Fund's investments in equity securities may include common stocks and securities convertible into or exchangeable for common stocks. Such investments may expose the Fund to additional risks.

Common Stock. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.
Convertible Securities. Convertible securities are subject to the risk that the credit standing of the issuer may have an effect on the convertible securities' investment value. Convertible securities are also sensitive to movements in interest rates.

Foreign Currency Forward Contracts Risk
Foreign currency forward contracts, including non-deliverable forwards ("NDFs"), are derivative instruments pursuant to a contract with a counterparty to pay a fixed price for an agreed amount of securities or other underlying assets at an agreed date or to buy or sell a specific currency at a future date at a price set at the time of the contract. The use of foreign currency forward contracts may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities or currencies underlying the foreign currency forward contract.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks 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 and financial reporting standards, (5) increased volatility, (6) less government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays in transaction settlement in some foreign markets.

Futures Contracts Risk
Futures contracts are derivative instruments 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 that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience potentially dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index, 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).

Hedging Risk
If the Fund uses a hedging instrument at the wrong time or judges the market conditions incorrectly, or the hedged instrument does not correlate to the risk sought to be hedged, the hedge might be unsuccessful, reduce the Fund's return, or create a loss. In addition, hedges, even when successful in mitigating risk, may not prevent the Fund from experiencing losses on its investments, and therefore the use of hedging strategies may reduce the Fund's return, or create a loss.

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

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

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

Market Risk
The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably based on overall economic conditions and other factors. The value of a security may decline due to general market conditions which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investment sentiment generally. Changes in the financial condition of a single issuer can impact a market as a whole. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Market Timing Risk
Because the Fund invests in foreign securities, or it has exposure to foreign securities through the derivatives it holds, it is particularly subject to the risk of market timing activities. 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 portfolio manager's ability to execute efficient investment strategies. Because of specific types of securities in which the Fund may invest, it could be subject to the risk of market timing activities by shareholders.

Multiple Sub-Advisor Risk
The Manager may allocate the Fund's assets among multiple sub-advisors, each of which is responsible for investing its allocated portion of the Fund's assets. To a significant extent, the Fund's performance will depend on the success of the Manager in allocating the Fund's assets to sub-advisors and its selection and oversight of the sub-advisors.

Other Investment Companies Risk
The Fund may invest in shares of other registered investment companies, including money market funds. 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 and will be subject to the risks associated with investments in those companies. For example, money market funds are subject to interest rate risk, credit risk, and market risk.

Securities Lending Risk
To the extent the Fund lends its securities, it may be subject to the following risks: i) borrowers of the Fund's securities typically provide collateral in the form of cash that is reinvested in securities, ii) the securities in which the collateral is invested may not perform sufficiently to cover the return collateral payments owed to borrowers, iii) delays may occur in the recovery of securities from borrowers, which could interfere with the Fund's ability to vote proxies or to settle transactions, and iv) there is the risk of possible loss of rights in the collateral should the borrower fail financially.

Securities Selection Risk
Securities selected by the sub-advisors or the Manager for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objectives.

Segregated Assets Risk
In connection with certain transactions that may give rise to future payment obligations, including futures and forward contracts, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the obligation. Segregated assets cannot be sold while the position they are covering is outstanding, unless they are replaced with other assets of equal value. The need to maintain cash or other liquid securities in segregated accounts could limit the Fund's ability to pursue other opportunities as they arise.

Small and Mid-Capitalization Companies Risk
Investing in the securities of small and mid-capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies. Since small and mid-capitalization companies may have narrower commercial markets and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity, and they can be particularly sensitive to expected changes in interest rates, borrowing costs and earnings. In general, these risks are greater for small-capitalization companies than for mid-capitalization companies.

Valuation Risk
The Fund may value certain assets at a price different from the price at which they can be sold. This risk may be especially pronounced for investments that are illiquid or which may become illiquid.

Value Stocks Risk
Value stocks are subject to the risk that their intrinsic value may never be realized by the market or that their prices may decline. The Fund's investments in value stocks seek to limit potential downside price risk over time; however, value stock prices still may decline substantially. In addition, the Fund may produce more modest gains as a trade-off for this potentially lower risk. The Fund's investment in value stocks could cause the Fund to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

The bar chart and table below provide an indication of risk by showing how the Fund's performance has varied from year to year. The table shows how the Fund's performance compares to a broad-based market index.

The chart and the table show the performance of the Fund's Investor Class shares for all periods. The Fund began offering Institutional Class shares on August 7, 1991, Investor Class shares on August 1, 1994, Advisor Class shares on May 1, 2003, Y Class shares on August 3, 2009, A Class shares on May 17, 2010, C Class shares on September 1, 2010 and R6 Class shares on February 28, 2017. In the table below, the performance of the Investor Class is shown for the A Class and C Class shares and the performance of the Institutional Class is shown for Y Class and R6 Class shares prior to the dates that such newer share classes were first offered. In each case, the older share classes would have had similar annual returns to the newer share classes because the shares are invested in the same portfolio securities. However, the older share classes had different expenses than the newer share classes. You may obtain updated performance information on the Fund's website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 23% of the average value of its portfolio.

Under normal circumstances, at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes) are invested in equity securities of large market capitalization U.S. companies. These companies have market capitalizations within the market capitalization range of the companies in the Russell 1000® Index at the time of investment. The Russell 1000 Index measures the performance of the 1,000 largest U.S. companies based on total market capitalization. As of December 31, 2018, the Russell 1000 Index consisted of companies with market capitalization of $472 million and greater.

The Fund's investments may include common stocks, real estate investment trusts ("REITs"), American Depositary Receipts ("ADRs") and U.S. dollar-denominated foreign stocks traded on U.S. exchanges (collectively referred to as "stocks").

The Manager allocates the assets of the Fund among different sub-advisors. The Manager believes that this strategy may help the Fund outperform other investment styles over the longer term while reducing volatility and downside risk. The Fund's sub-advisors select stocks that, in their opinion, have most or all of the following characteristics (relative to the S&P 500® Index):

above-average earnings growth potential,
below-average price to earnings ratio,
below-average price to book value ratio, and
above-average dividend yields.

Each of the Fund's sub-advisors determines the earnings growth prospects of companies based upon a combination of internal and external research using fundamental analysis and considering changing economic trends. The sub-advisors typically seek to invest in companies that they believe are undervalued at the time of purchase. The decision to sell a stock is typically based on the belief that the company is no longer considered undervalued or shows deteriorating fundamentals, or that better investment opportunities exist in other stocks. The Fund may have significant exposure to the Financial Services sector. However, as the sector composition of the Fund's portfolio changes over time, the Fund's exposure to the Financial Services sector may be lower at a future date, and the Fund's exposure to other market sectors may be higher.

The Fund may invest cash balances in other investment companies, including money market funds, and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs. The Fund may seek to earn additional income by lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis.

There is no assurance that the Fund will achieve its investment objectives and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund, which are described in alphabetical order and not in order of importance or potential exposure, are:

Cybersecurity and Operational Risk
The Fund and its service providers, and shareholders' ability to transact with the Fund, may be negatively impacted due to operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality.

Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Equity Investments Risk
Equity securities are subject to investment and market risk. The Fund's investments in equity securities may include common stocks, REITs, depositary receipts, and U.S. dollar-denominated foreign stocks traded on U.S. exchanges. Such investments may expose the Fund to additional risks.

Common Stock. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.
Depositary Receipts. Depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency exchange rate fluctuations, political and financial instability in the home country of a particular depositary receipt or foreign stock, less liquidity and more volatility, less government regulation and supervision and delays in transaction settlement.
REITs. Investments in REITs are subject to the risks associated with investing in the real estate industry such as adverse developments affecting the real estate industry and real property values. REITs also are dependent upon the skills of their managers and are subject to heavy cash flow dependency or self-liquidation. Domestic REITs could be adversely affected by failure to qualify for tax-free "pass-through" of distributed net income and net realized gains under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. REITs typically incur fees that are separate from those incurred by the Fund. Accordingly, the Fund's investment in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs' operating expenses, in addition to paying Fund expenses. The value of REIT common stock may decline when interest rates rise.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks 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 and financial reporting standards, (5) increased price volatility, (6) less government regulation and supervision of foreign stock exchanges, brokers and listed companies; and (7) delays in transaction settlement in some foreign markets.
