Important Information: Indexes are unmanaged and one cannot invest directly in an index. Because the Fund has a flexible approach to investing, the risks of the Fund are likewise varied. The primary risks fall into one of several broad categories including high yield securities risk, credit risk, foreign investment risk, derivatives risk, interest rate risk and non-diversification risk. Investing in foreign denominated and/or domiciled securities may involve heightened risk due to currency fluctuations, and economic and political risks, which may be enhanced in emerging markets. Mortgage and asset-backed securities may be sensitive to changes in interest rates, subject to early repayment risk and their value may fluctuate in response to the market’s perception of issuer creditworthiness; while generally supported by some form of government or private guarantee, there is no assurance that private guarantors will meet their obligations. Income from municipal bonds may be subject to state and local taxes and at times the alternative minimum tax. Derivatives may involve certain costs and risks such as liquidity, interest rate, market, credit, management and the risk that a position could not be closed when more advantageous. Investing in derivatives could result in losing more than the amount invested. Diversification does not ensure against loss. Investing in debt securities entails interest rate risk, which is the risk that debt securities will decrease in value with increases in market interest rates. Bonds and bond funds with longer durations tend to be more sensitive and more volatile than securities with shorter durations; bond prices generally fall as interest rates rise. Please see the prospectus for a complete discussion of the Fund’s risks. There can be no assurances that the investment objectives of this Fund will be met.

Any opinions herein, including forecasts, reflect our judgment as of the end of the reporting period and are subject to change. Each advisor’s strategies and the Fund’s portfolio composition will change depending on economic and market conditions. This report is not a complete analysis of market conditions and therefore, should not be relied upon as investment advice. Although economic and market information has been compiled from reliable sources, American Beacon Advisors, Inc. makes no representation as to the completeness or accuracy of the statements contained herein.

American Beacon Funds August 31, 2013

Dear Shareholders,   The past 12 months have been challenging for global bond markets. Concern over a possible tapering of the U.S. Federal Reserve’s quantitative easing program caused a rise in interest rates with the yield on the benchmark 10-year U.S. Treasury note approaching three percent.   The upshot was a very challenging 12 months for global fixed-income investors. The Barclays Capital U.S. Aggregate Index, the flagship index for the bond market, lost 2.47% of its value over the period under review.

• For the 12-month period ended August 31, 2013, the American Beacon Flexible Bond Fund (Investor Class) returned 0.38%.

We believe that the bond funds best positioned to succeed in this new environment are those that can adapt to different landscapes, with the flexibility to deal with changing interest rates. We’re encouraged by the way our American Beacon Flexible Bond Fund has been able to negotiate these challenges.

Thank you for your continued investment in the American Beacon Funds. For additional information about the Funds or to access your account information, please visit our website at www.americanbeaconfunds.com.

Best Regards,

Gene L. Needles, Jr.

Global Bond Market Overview

August 31, 2013 (Unaudited)

The primary factor affecting the global bond market over the 12 months prior to August 31, 2013, was the scope of central bank interventions around the world, led by the Federal Reserve Bank in the U.S. The turning point for this period came in May, when Federal Reserve chairman Ben Bernanke indicated that the Fed’s asset-purchasing program would be coming to an end in the near future. With interest rates low in most parts of the global economy, it was a challenging landscape for fixed-income investors, one in which the Barclays Capital U.S. Aggregate Index lost 2.5% over the period.

The most important reflation initiatives affecting the world’s bond markets came from the world’s leading central banks. The European Central Bank (ECB) backed up its 2011-announced Longer-Term Refinancing Operations program in July 2012 with a pledge from ECB President Mario Draghi to do “whatever it takes to preserve the euro.” Mervyn King, the former governor of the Bank of England, admitted that simply targeting inflation was no longer enough to prevent another future economic calamity. In the same vein, current Governor Mark Carney said that nominal income level targets might serve economic interests better, especially in the current environment.

In Asia, the Bank of Japan faced political pressure to lift its inflation target and weaken the currency. Chinese authorities veered from fighting real estate speculation toward boosting growth in pursuit of an expansion less dependent on exports.

In the U.S., the Federal Open Market Committee pledged more quantitative easing with no specific endpoint. It also tied the end of its zero interest-rate policy to achieving a 7% unemployment rate as long as “inflation between one and two years ahead is projected to be no more than a half percentage point above the Committee’s 2% longer-run goal, and longer-term inflation expectations continue to be well anchored.”

There was some positive news investors could take from the bond markets. The “risk-on/risk-off” dynamic from 2008 to 2011 started to change throughout 2012, and the breakdown in risk correlations was one of the clues that a more positive outcome was playing out. The divergence between stock and commodities prices was one

example. The simultaneous rise in Italian and Spanish yields along with the drop in Polish and Mexican yields earlier in the year was another. Investors were becoming more selective about where risk was concentrated.

The yield on 10-year U.S. Treasury notes was under 2% on May 21, the day before Chairman Bernanke’s testimony made tapering the dominant theme in the second quarter. By August 31, that yield had risen to 2.78%. Ten-year U.S. TIPS yields rose from negative 40 basis points (-0.40%) to over 60 basis points (0.60%) over the same period. U.S. investment-grade corporates and long-term mortgage yields rose as well. Meanwhile, there were huge dislocations in the emerging markets. During the same May 21 to August 31 period, Mexican long bond yields rose more than 160 basis points (1.60%), while the yield on Brazilian three-year debt surged more than 250 basis points (2.50%).

The period ended with the global markets in a tempest over the timeline for tapering the scale of asset purchases by the U.S. Federal Reserve. If the U.S. economy continues to improve and the unemployment rate stays on its current trajectory lower, then short-term interest rates could start to normalize sometime in 2015. It would be reasonable under those conditions to expect the quantitative easing program to end before that, sometime in 2014.

Performance Overview

August 31, 2013 (Unaudited)

The Investor Class of the Flexible Bond Fund (the “Fund”) returned 0.38% for the twelve months ended August 31, 2013. The Fund outperformed the BofA Merrill Lynch 3-Month LIBOR Index (the “Index”) return of 0.34%. The performance objective of the Fund is to generate positive total returns over a full market cycle and it successfully achieved positive absolute returns during the twelve-month period.

1. Performance shown is historical and is not indicative of future returns. Investment returns and principal value will vary, and shares may be worth more or less at redemption than at original purchase. Performance shown is as of date indicated, and current performance may be lower or higher than the performance data quoted. To obtain performance as of the most recent month end, please visit www.americanbeaconfunds.com or call 1-800-967-9009. Fund performance in the table above does not reflect the deduction of taxes a shareholder would pay on distributions or the redemption of shares. A Class shares have a maximum sales charge of 4.75%. The maximum contingent deferred sales charge for the C Class is 1.00% for shares redeemed within one year of the date of purchase.

2. A portion of the fees charged to each Class of the Fund was waived since inception. Performance prior to waiving fees was lower than the actual returns shown since inception.

3. The BofA Merrill Lynch U.S. Dollar 3-Month LIBOR Index represents the London interbank offered rate (LIBOR) with a constant 3-month average maturity. LIBOR is a composite of the rates of interest at which banks borrow from one another in the London market, and it is a widely used benchmark for short-term interest rates. The Barclays Capital U.S. Aggregate Index is a market weighted index of government, corporate, mortgage-backed and asset-backed fixed-rate debt securities of all maturities.

4. The total annual Fund operating expense ratio set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A and C Class shares was 1.44%, 1.51%, 1.78%, 1.95% and 2.76%, respectively. The expense ratios above may vary from the expense ratios presented in other sections of this report that are based on expenses incurred during the period covered by this report.

The Fund’s focus on investing in high quality fixed income securities proved beneficial in achieving its return objective. The majority of the assets are invested in investment grade securities, which generally were positive during the period. However, the Fund’s investments within the U.S. Treasury and U.S. TIPS sectors generated negative returns during the period (down 1.9% and 8.1%, respectively).

Despite the negative returns generated by U.S. Government related securities, Foreign Sovereign investments helped offset some of those losses and experienced gains (up 1.6%). A smaller portion of the Fund’s assets were invested in non-investment grade securities, and this positioning was rewarded as these securities typically outperformed the higher rated securities.

The Fund’s Corporate fixed income exposure provided a positive contribution to the return generated over the period. Among the Corporate holdings, positions in the Finance sector had the most significant impact. The Finance sector represented 15.4% of the Fund’s assets and experienced strong returns (up 4.1%).

Securities with a duration of less than three years had a positive impact during the period. The Treasury yield curve experienced increased yields from securities with a maturity of two years and greater, so the Fund’s emphasis on short duration investments helped.

Performance Overview

August 31, 2013 (Unaudited)

The Fund has the flexibility to utilize derivative instruments and will do so to enhance return, hedge risk, gain efficient exposure to an asset class or to manage liquidity. When considering the Fund’s use of derivatives, it is important to note that the Fund does not use derivatives for the purpose of creating financial leverage. During the period, the Fund experienced modest declines from the use of derivatives in swaps.

Looking forward, the Fund’s investment managers will continue to allocate investments across a wide range of global investment opportunities, seeking to achieve the Fund’s goal of positive total returns regardless of market conditions over a full market cycle.

Fund Expenses

August 31, 2013 (Unaudited)

Fund Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on shares purchased and (2) ongoing costs, including management fees, administrative service fees, distribution (12b-1) fees, and other Fund expenses. The examples below are intended to help you understand the ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000 invested at the beginning of the period in each Class and held for the entire period from March 1, 2013 through August 31, 2013.

Actual Expenses

The “Actual” lines of the table provide information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period. Shareholders of the Investor and Institutional Classes that invest in the Fund through an IRA or Roth IRA may be subject to a custodial IRA fee of $15 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $15 higher.

Hypothetical Example for Comparison Purposes

The “Hypothetical” lines of the table provide information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the Fund’s actual return). You may compare the ongoing costs of investing in the Fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Shareholders of the Investor and Institutional Classes that invest in the Fund through an IRA or Roth IRA may be subject to a custodial IRA fee of $15 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $15 higher.

You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs charged by the Fund, such as sales charges (loads). Similarly, the expense examples for other funds do not reflect any transaction costs charged by those funds, such as sales charges (loads), redemption fees or exchange fees. Therefore, the “Hypothetical” lines of the table are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If you were subject to any transaction costs during the period, your costs would have been higher.

	Beginning Account Value 3/1/13		Ending Account Value 8/31/13		Expenses Paid During  Period* 3/1/13-8/31/13
Institutional Class
Actual	$	1,000.00	$	971.05	$	4.47
Hypothetical **	$	1,000.00	$	1,020.67	$	4.58
Y Class
Actual	$	1,000.00	$	970.65	$	4.92
Hypothetical **	$	1,000.00	$	1,020.21	$	5.04
Investor Class
Actual	$	1,000.00	$	969.26	$	6.30
Hypothetical **	$	1,000.00	$	1,018.80	$	6.46
A Class
Actual	$	1,000.00	$	968.68	$	6.90
Hypothetical **	$	1,000.00	$	1,018.20	$	7.07
C Class
Actual	$	1,000.00	$	965.59	$	10.60
Hypothetical **	$	1,000.00	$	1,014.42	$	10.87

* Expenses are equal to the Fund’s annualized expense ratios for the six-month period of 0.90%, 0.99%, 1.27%, 1.39% and 2.14% for the Institutional, Y, Investor, A and C Classes respectively, multiplied by the average account value over the period, multiplied by the number derived by dividing the number of days in the most recent fiscal half-year (184) by days in the year (365) to reflect the half-year period.

** 5% return before expenses.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of

American Beacon Flexible Bond Fund:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the American Beacon Flexible Bond Fund (one of the funds constituting the American Beacon Funds) (the “Fund”), as of August 31, 2013, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Funds’ internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2013, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the American Beacon Flexible Bond Fund at August 31, 2013, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

* Inflation Swap

⁽¹⁾  If the Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

⁽²⁾  If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

⁽³⁾  Implied credit spreads, represented in absolute terms, utilized in determining the fair value of credit default swaps agreements on corporate issues and sovereign issues of an emerging country as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽⁴⁾  The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

⁽⁵⁾  The quoted market prices and resulting values for credit default swaps on asset-backed securities and credit indices serve as an indicator of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/ sold as of the period end. Increasing fair values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the referenced entity’s credit soundness and greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

** Knockout FX Options - An option with a built in mechanism to expire worthless, should a specified price level be exceeded. A knock-out option sets a cap to the level an option can reach, in favor of the holder. As knock-out options limit the profit potential for the option buyer, they can be purchased for a smaller premium than an equivalent option without a knock-out stipulation.

Notes to Financial Statements

August 31, 2013

1. Organization and Significant Accounting Policies

American Beacon Funds (the “Trust”), which is comprised of twenty-four Funds, is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company. These financial statements and notes to the financial statements relate to the American Beacon Flexible Bond Fund (the “Fund”), a series of the Trust.

American Beacon Advisors, Inc. (the “Manager”) is a wholly-owned subsidiary of Lighthouse Holdings, Inc. and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services to the Trust and other investors.

The Flexible Bond Fund is a commodity pool, as defined in the regulations of the Commodity Futures Trading Commission (the “CFTC”) and operated by the Manager, a commodity pool operator registered with the CFTC.

Class Disclosure

The Fund has multiple classes of shares designed to meet the needs of different groups of investors. The following table sets forth the differences amongst the classes:

Class:	Offered to:
Institutional Class	Investors making an initial investment of $250,000
Y Class	Investors making an initial investm ent of $100,000
Investor Class	General public and investors investing directly or through an intermediary
A Class	General public and investors investing through an intermediary with applicable sales charges
C Class	General public and investors investing through an intermediary with applicable sales charges

Each class offered by the Trust has equal rights as to assets and voting privileges. Income and non-class specific expenses are allocated daily to each class on the basis of the relative net assets. Realized and unrealized capital gains and losses of each class are allocated daily based on the relative net assets of each class of the Fund. Class specific expenses, where applicable, currently include administrative service fees, service fees, and distribution fees and vary amongst the classes as described more fully in Note 2.

New Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities. The amendments in the ASU enhance disclosures about offsetting of financial assets and liabilities to enable investors to understand the effect of these arrangements on a fund’s financial position. In January 2013, FASB issued ASU No. 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. The amendments in ASU No. 2013-01 clarify the scope of disclosures required by ASU No. 2011-11. These ASUs are effective for annual periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Fund believes the adoption of these ASUs will not have a material impact on its financial statement disclosures.

2. Transactions with Affiliates

Management Agreement

The Trust and the Manager are parties to a Management Agreement that obligates the Manager to provide or oversee the provision of all investment advisory and portfolio management services. Investment assets of the Fund are managed by multiple investment advisors which have entered into separate investment advisory agreements with the Manager. As compensation for performing the duties required under the

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2013

Management Agreement, the Manager receives from the Fund 0.05% of the average daily net assets plus amounts paid by the Manager to the investment advisors hired by the Manager to direct investment activities of the Fund. Management fees for the year ended August 31, 2013 were as follows (dollars in thousands):

Management Fee Rate	Management Fee		Amounts paid  to Investment Advisors		Net Amounts Retained by Manager
0.59%	$	778	$	713	$	65

Administrative Services Agreement

The Manager and the Trust entered into an Administrative Services Agreement which obligates the Manager to provide or oversee administrative services to the Fund. As compensation for performing the duties required under the Administrative Services Agreement, the Manager receives an annualized fee of 0.30% of the average daily net assets of the Institutional, Y, and Investor Classes of the Fund and 0.40% of the average daily net assets of the A and C Classes of the Fund.

Distribution Plans

The Fund, except for the A and C Classes of the Fund, have adopted a “defensive” Distribution Plan (the “Plan”) in accordance with Rule 12b-1 under the Act, pursuant to which no fees may be charged to the Fund for distribution purposes. However, the Plan authorizes the management and administrative service fees received by the Manager and the investment advisor hired by the Manager to be used for distribution purposes. Under this Plan, the Fund does not intend to compensate the Manager or any other party, either directly or indirectly, for the distribution of Fund shares.

Separate Distribution Plans (the “Distribution Plans”) have been adopted pursuant to Rule 12b-1 under the Act for the A and C Classes of the Fund. Under the Distribution Plans, as compensation for distribution assistance, the Manager receives an annual fee of 0.25% of the average daily net assets of the A Class and 1.00% of the average daily net assets of the C Class of the Fund. The fee will be payable without regard to whether the amount of the fee is more or less than the actual expenses incurred in a particular month by the Manager for distribution assistance.

Service Plans

The Manager and the Trust entered into Service Plans that obligate the Manager to oversee additional shareholder servicing of the Y, Investor, A, and C Classes. As compensation for performing the duties required under the Service Plans, the Manager receives 0.10% of the average daily net assets of Y Class, 0.15% of the average daily net assets of the A and C Classes, and up to 0.375% of the average daily net assets of the Investor Class of the Fund.

Interfund Lending Program

Pursuant to an exemptive order issued by the Securities and Exchange Commission (“SEC”), the Fund, along with other registered investment companies having management contracts with the Manager, may participate in an interfund lending program as a borrower. This program provides an alternative credit facility allowing the Fund to borrow from other participating Funds. During the year ended August 31, 2013, the Fund did not utilize the credit facility.

Of these amounts, $56,731 is receivable from the Manager, as of August 31, 2013. The Fund has adopted an Expense Reimbursement Plan whereby the Manager may seek repayment of expenses reimbursed for a period of up to three years. However, reimbursement will occur only if the Class’s average net assets have grown or expenses have declined sufficiently to allow reimbursement without causing its expense ratio to exceed the previously agreed upon contractual expense limit. The reimbursed expenses listed above will expire in 2016. The carryover of excess expenses potentially reimbursable to the Manager but not recorded as a liability is $146,216 and $274,377 expiring in 2014 and 2015, respectively. The Fund did not record a liability for potential reimbursements, due to the current assessment that a reimbursement is unlikely.

Sales Commissions

The Fund’s distributor, Foreside Fund Services, LLC (“Foreside”) may receive a portion of A Class sales charges from broker dealers and it may be used to offset distribution related expenses. For the year ended August 31, 2013 Foreside collected $20,106 from the sale of A Class Shares.

A contingent deferred sales charge (“CDSC”) of 0.50% will be deducted with respect to Class A Shares on certain purchases of $250,000 or more that are redeemed in whole or part within 12 months of purchase, unless waived as discussed in the Prospectus. Any applicable CDSC will be 0.50% of the lesser of the original purchase price or the value of the redemption of the Class A Shares redeemed. During the year ended August 31, 2013, there were no CDSC fees collected for the Fund.

A CDSC of 1.00% will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless waived as discussed in the Prospectus. Any applicable CDSC will be 1.00% of the lesser of the original purchase price or the value of the redemption of the Class C Shares redeemed. During the year ended August 31, 2013 CDSC charges of $2,343 were collected.

3. Security Valuation and Fair Value Measurements

Investments are valued at the close of the New York Stock Exchange (the “Exchange”), normally 4 p.m. ET, each day that the Exchange is open for business. Equity securities including exchange-traded funds (“ETFs”) for which market quotations are available are valued at the last sale price or official closing price (closing bid price or last evaluated quote if no sale has occurred) on the primary market or exchange on which they trade.

Debt securities (other than short-term securities) normally are valued on the basis of prices provided by an independent pricing service and may take into account appropriate factors such as institution-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The prices of debt securities may be determined using quotes obtained from brokers.

Investments in open-end mutual funds are valued at the closing net asset value (“NAV”) per share of the mutual fund on the day of valuation. Investment grade short-term obligations with 60 days or less to maturity are valued using the amortized cost method, which approximates market value.

Securities for which the market prices are not readily available or are not reflective of the fair value of the security, as determined by the Manager, will be priced at fair value following procedures approved by the Trust’s Board of Trustees (the “Board”).

Futures contracts are valued based upon their quoted daily settlement prices. Upon entering into a futures contract, the Fund is required to deposit with its futures broker, an amount of cash or U.S. Government and Agency Obligations in accordance with the initial margin requirements of the broker or exchange. Futures contracts are marked to market daily and an appropriate payable or receivable for the change in value (“variation margin”) is recorded by the Fund. Gains or losses are recognized, but not considered realized until the contracts expire or are closed. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed on the Statement of Assets and Liabilities.

Other investments, including restricted securities, and those financial instruments for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the Valuation Committee, established by the Fund’s Board.

For valuation purposes, the last quoted prices of non-U.S. equity securities may be adjusted under the circumstances described below. If a Manager determines that developments between the close of a foreign market and the close of the Exchange will, in its judgment, materially affect the value of some or all of a fund’s portfolio securities, the Manager will adjust the previous closing prices to reflect what it believes to be the fair value of the securities as of the close of the Exchange. In deciding whether it is necessary to adjust closing prices to reflect fair value, the Manager reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U.S. markets that represent foreign securities and baskets of foreign securities. The Valuation Committee may also fair value securities in other situations, such as when a particular foreign market is closed but a Fund is open. The Fund uses outside pricing services to provide closing prices and information to evaluate and/or adjust those prices. As a means of evaluating its security valuation process, the Valuation Committee routinely compares closing prices, the next day’s opening prices in the same markets, and adjusted prices.

Valuation Inputs

Various inputs may be used to determine the value of the Fund’s investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

Level 1 -	Quoted prices in active markets for identical securities.
Level 2 -	Prices determined using other significant observable inputs. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and others. Level 2 securities are fixed-income securities that are valued using observable inputs as stated above.
Level 3 -	Prices determined using other significant unobservable inputs. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in pricing an investment, and would be based on the best information available.

Level 1 and Level 2 trading assets and trading liabilities, at fair value.

Fixed income securities including corporate, convertible and municipal bonds and notes, U.S. government agencies, U.S. treasury obligations, sovereign issues, bank loans, convertible preferred securities and non-U.S. bonds are normally valued by pricing service providers that use broker dealer quotations, reported trades or valuation estimates from their internal pricing models. The service providers’ internal models use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar assets. Securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Fixed income securities purchased on a delayed-delivery basis are marked to market daily until settlement at the forward settlement date and categorized as Level 2 of the fair value hierarchy.

Mortgage-related and asset-backed securities are usually issued as separate tranches, or classes, of securities within each deal. These securities are also normally valued by pricing service providers that use broker dealer quotations or valuation estimates from their internal pricing models. The pricing models for these securities usually consider tranche-level attributes, current market data, estimated cash flows and market-based yield spreads for each tranche, and incorporates deal collateral performance, as available. Mortgage-related and asset-backed securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Common stocks, ETFs and financial derivative instruments, such as futures contracts or options contracts that are traded on a national securities exchange, are stated at the last reported sale or settlement price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy. Valuation adjustments may be applied to certain securities that are solely traded on a foreign exchange to account for the market movement between the close of the foreign market and the close of the Exchange. These securities are valued using pricing service providers that consider the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments. Securities using these valuation adjustments are categorized as Level 2 of the fair value hierarchy. Preferred securities and other equities traded on inactive markets or valued by reference to similar instruments are also categorized as Level 2 of the fair value hierarchy.

Investments in registered open-end investment management companies will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy. Investments in privately held investment funds which are redeemable within 90 days of the measurement date, will be valued based upon the NAVs of such investments and are categorized as Level 2 of the fair value hierarchy. Short-term investments having a maturity of 60 days or less are generally valued at amortized cost which approximates fair value. These investments are categorized as Level 2 of the fair value hierarchy.

Over-the-counter (“OTC”) financial derivative instruments, such as foreign currency contracts, options contracts, or swaps agreements, derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. These contracts are normally valued on the basis of broker dealer quotations or pricing service providers. Depending on the product and the terms of the transaction, the value of the financial derivative contracts can be estimated by a pricing service provider using a series of techniques, including simulation pricing models. The pricing models use inputs that are observed from actively quoted markets such as issuer details, indices, spreads, interest rates, curves, dividends and exchange rates. Financial derivatives that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

* Change in unrealized appreciation or (depreciation) attributable to Level 3 securities held at period end. This balance is included in the change in unrealized appreciation or (depreciation) on the Statement of Operations.

Security Transactions and Investment Income

Security transactions are recorded on the trade date of the security purchase or sale. The Fund may purchase securities with delivery or payment to occur at a later date. At the time the Fund enters into a commitment to purchase a security, the transaction is recorded and the value of the security is reflected in the NAV. The value of the security may vary with market fluctuations.

Dividend income, net of foreign taxes, is recorded on the ex-dividend date except certain dividends from foreign securities which are recorded as soon as the information is available to the Funds. Interest income is earned from settlement date, recorded on the accrual basis, and adjusted, if necessary, for accretion of discounts and amortization of premiums. For financial and tax reporting purposes, realized gains and losses are determined on the basis of specific lot identification.

Currency Translation

All assets and liabilities initially expressed in foreign currency values are converted into U.S. dollar values at the mean of the bid and ask prices of such currencies against U.S. dollars as last quoted by a recognized dealer. Income, expenses and purchases and sales of investments are translated into U.S. dollars at the rate of exchange prevailing on the respective dates of such transactions. The effect of changes in foreign currency exchange rates on investments is separately identified from the fluctuations arising from changes in market values of securities held and is reported with all other foreign currency gains and losses in the Fund’s Statement of Operations.

Dividends to Shareholders

Dividends from net investment income of the Fund normally will be declared and paid at least annually. Distributions, if any, of net realized capital gains are generally paid at least annually and recorded on the ex-dividend date.

Commission Recapture

The Fund has established brokerage commission recapture arrangements with certain brokers or dealers. If a Fund’s investment advisor chooses to execute a transaction through a participating broker, the broker rebates a portion of the commission back to the Fund. Any collateral benefit received through participation in the commission recapture program is directed exclusively to the Fund. This amount is reported with the net realized gain in the Fund’s Statement of Operations, if applicable. For the year ended August 31, 2013, the Fund did not have any commission recapture.

Allocation of Income, Expenses, Gains, and Losses

Income, expenses (other than those attributable to a specific class), gains, and losses are allocated daily to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated.

Other

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liability arising out of the performance of their duties to the Trust. In the normal course of business, the Trust enters into contracts that provide indemnification to the other party or parties against potential costs or liabilities. The Trust’s maximum exposure under these arrangements is dependent on claims that may be made in the future and, therefore, cannot be estimated. The Trust has had no prior claims or losses pursuant to any such agreement.

4. Securities and other Investments

Emerging Markets Debt

The Fund may invest in emerging markets dept. The Fund’s emerging markets debt securities may include obligations of government and corporations. As with any fixed income securities, emerging markets debt securities are subject to the risk of being downgraded in credit rating and to the risk of default. In the event of a default on any investments in foreign debt obligations, it may be more difficult for the Fund to obtain or to enforce a judgment against the issuers of such securities. With respect to debt issued by emerging markets governments, such issues may be unwilling to pay interest and repay principal when due, either due to inability to pay or submission to political pressure not to pay, and as a result my default, declare temporary suspensions of interest payments or require that the conditions of payments be renegotiated.

Repurchase Agreements

A repurchase agreement is a fixed income security in the form of an agreement between a Fund as purchaser and an approved counterparty as seller. The agreement is backed by collateral in the form of securities and/or cash transferred by the seller to the buyer to be held by an eligible third-party custodian. Under the agreement a Fund acquires securities from the seller and the seller simultaneously commits to repurchase the securities at an agreed upon price and date, normally within a week. The price for the seller to repurchase the securities is greater than a Fund’s purchase price, reflecting an agreed upon “interest rate” that is effective for the period of time the purchaser’s money is invested in the security. During the term of the repurchase agreement, a Fund monitors on a daily basis the market value of the collateral subject to the agreement and, if the market value of the securities falls below the seller’s repurchase amount provided under the repurchase agreement, the seller is required to transfer additional securities or cash collateral equal to the amount by which the market value of the securities falls below the repurchase amount. Repurchase agreements may exhibit the economic characteristics of loans by a Fund.

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

Notes to Financial Statements

August 31, 2013

The Funds may enter into repurchase agreements with member banks of the Federal Reserve System or registered broker-dealers who, in the opinion of the Manager, present a minimal risk of default during the term of the agreement. The underlying securities which serve as collateral for repurchase agreements may include fixed income and equity securities such as U.S. Government and agency securities, municipal obligations, corporate obligations, asset-backed securities, mortgage-backed securities, common and preferred stock, American Depository Receipts, exchange-traded funds and convertible securities. There is no percentage restriction on each Fund’s ability to enter into repurchase agreements with terms of seven days or less.

Certificate of Deposit

A savings certificate entitling the bearer to receive interest. A Certificate of Deposit (“CD”) bears a fixed maturity date, has a specified fixed interest rate, and can be issued in any denomination. CDs are generally issued by commercial banks and are currently insured by the Federal Deposit Insurance Corporation (FDIC) up to a maximum of $250,000. CDs are generally offered at terms ranging from one month to five years.

Inflation-Indexed Bonds

The Fund may invest in inflation-indexed bonds. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted based on the rate of inflation. The interest rate on these bonds is generally fixed at issuance at a rate lower than typical bonds. Over the life of an inflation-indexed bond, however, interest will be paid based on a principal value, which is adjusted for inflation. Any increase or decrease in the principal amount of an inflation-indexed bond will be included as interest income on the Statement of Operations, even though investors do not receive their principal until maturity.

Payment In-Kind Securities

The Fund may invest in payment in-kind securities. Payment in-kind securities (“PIKs”) give the issuer the option at each interest payment date of making interest payments in either cash or additional debt securities. Those additional debt securities usually have the same terms, including maturity dates and interest rates, and associated risks as the original bonds. The daily market quotations of the original bonds may include the accrued interest (referred to as a dirty price) and require a prorata adjustment from the unrealized appreciation or depreciation on investment to interest receivable in the Statement of Assets and Liabilities.

Restricted Securities

The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities may be sold privately, but are required to be registered or exempted from such registration before being sold to the public. Private placement securities are generally considered to be restricted except for those securities traded between qualified institutional investors under the provisions of Rule 144A of the Securities Act of 1933. Disposal of restricted securities may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult to achieve. Restricted securities outstanding as of August 31, 2013 are disclosed in the Notes to the Schedule of Investments.

High-Yield Securities

Non-investment-grade securities are rated below the four highest credit grades by at least one of the public rating agencies (or are unrated if not publicly rated). Participation in high-yielding securities transactions generally involves greater returns in the form of higher average yields. However, participation in such transactions involves greater risks, including sensitivity to economic changes, solvency, and relative liquidity in the secondary trading market. Lower ratings may reflect a greater possibility that the financial condition of the issuer, or adverse changes in general economic conditions, or both, may impair the ability of the issuer to make payments of interest and principal. The prices and yields of lower-rated securities generally fluctuate more than higher-quality securities, and such prices may decline significantly in periods of general economic difficulty or rising interest rates.

Real Estate Investment Trusts

The Funds may own shares of real estate investment trusts (“REITs”) which report information on the source of their distributions annually. The Funds re-characterize distributions received from REIT investments based on information provided by the REITs into the following categories: ordinary income, long-term capital gains, and return of capital. If information is not available on a timely basis from the REITs, the re-characterization will be estimated based on available information, which may include the previous year allocation. If new or additional information becomes available from the REITs at a later date, a re-characterization will be made the following year. These re-characterizations are not recorded for financial statement purposes, but as an adjustment to the calculation of taxable income.

Other Investment Company Securities and Other Exchange Traded Products

The Funds may invest in shares of other investment companies, including open-end funds, closed-end funds, business development companies, ETFs, exchange-traded notes (“ETNs”), unit investment trusts, and other investment companies of the Trust. The Funds may invest in investment company securities advised by the Manager or a sub-advisor. Investments in the securities of other investment companies may involve duplication of advisory fees and certain other expenses. By investing in another investment company, a Fund becomes a shareholder of that investment company. As a result, Fund shareholders indirectly will bear a Fund’s proportionate share of the fees and expenses paid by shareholders of the other investment company, in addition to the fees and expenses Fund shareholders directly bear in connection with the Fund’s own operations. These other fees and expenses are reflected as Acquired Fund Fees and Expenses and are included in the Fees and Expenses Table for the Fund in its Prospectus, if applicable. Investments in other investment companies may involve the payment of substantial premiums above the value of such issuer’s portfolio securities.

Mortgage-Related and Other Asset-Backed Securities

The Fund may invest in mortgage or other asset-backed securities (“ABS”). These securities may include mortgage instruments issued by U.S. government agencies (“agency mortgages”) or those issued by private entities (“non-agency mortgages”). Specific types of instruments may include mortgage pass-through securities, collateralized mortgage obligations (“CMOs”), commercial mortgage-backed securities, mortgage dollar rolls, CMO residuals, stripped mortgage-backed securities and other securities that directly or indirectly represent a participation in, or are secured by a payable from, mortgage loans on real property. The value of the Fund’s mortgage-backed securities (“MBS”) may be affected by, among other things, changes or perceived changes in interest rates, factors concerning the interests in and structure of the issuer or the originator of the mortgage, or the quality of the underlying assets. The mortgages underlying the securities may default or decline in quality or value. Through its investments in MBS, a Fund has exposure to subprime loans, Alt-A loans and non-conforming loans as well as to the mortgage and credit markets generally. Underlying collateral related to subprime, Alt-A and non-conforming mortgage loans has become increasingly susceptible to defaults and declines in quality or value, especially in a declining residential real estate market. In addition, regulatory or tax changes may adversely affect the mortgage securities markets as a whole.

Mortgage-Backed Securities

MBS often have stated maturities of up to thirty years when they are issued, depending upon the length of the mortgages underlying the securities. In practice however, unscheduled or early payments of principal and interest on the underlying mortgages may make the securities’ effective maturity shorter than this, and the prevailing interest rates may be higher or lower than the current yield of the Fund’s portfolio at the time resulting in reinvestment risk.

46

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2013

Rising or high interest rates may result in slower than expected principal payments which may tend to extend the duration of MBS, making them more volatile and more sensitive to changes in interest rates. This is known as extension risk.

MBS may have less potential for capital appreciation than comparable fixed income securities due to the likelihood of increased prepayments of mortgages resulting from foreclosures or declining interest rates. These foreclosed or refinanced mortgages are paid off at face value (par) or less, causing a loss, particularly for any investor who may have purchased the security at a premium or a price above par. In such an environment, this risk limits the potential price appreciation of these securities.

Agency Mortgage-Backed Securities

Certain MBS may be issued or guaranteed by the U.S. government or a government sponsored entity, such as Fannie Mae (the Federal National Mortgage Association) or Freddie Mac (the Federal Home Loan Mortgage Corporation). Although these instruments may be guaranteed by the U.S. government or a government sponsored entity, many such MBS are not backed by the full faith and credit of the United States and are still exposed to the risk of non-payment.

Privately Issued Mortgage-Backed Securities

MBS held by a Fund may be issued by private issuers including commercial banks, savings associations, mortgage companies, investment banking firms, finance companies and special purpose finance entities (called special purpose vehicles or SPVs) and other entities that acquire and package mortgage loans for resale as MBS. These privately issued non-agency MBS may offer higher yields than those issued by government agencies, but also may be subject to greater price changes than governmental issues. Subprime loans refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their loans. Alt-A loans refer to loans extended to borrowers who have incomplete documentation of income, assets, or other variables that are important to the credit underwriting processes. Non-conforming mortgages are loans that do not meet the standards that allow purchase by government-sponsored enterprises. MBS with exposure to subprime loans, Alt-A loans or non-conforming loans have had in many cases higher default rates than those loans that meet government underwriting requirements. The risk of non-payment is greater for MBS that are backed by mortgage pools that contain subprime, Alt-A and non-conforming loans, but a level of risk exists for all loans.

Unlike agency MBS issued or guaranteed by the U.S. government or a government-sponsored entity (e.g., Fannie Mae (the Federal National Mortgage Association) and Freddie Mac (the Federal Home Loan Mortgage Corporation), MBS issued by private issuers do not have a government or government-sponsored entity guarantee, but may have credit enhancements provided by external entities such as banks or financial institutions or achieved through the structuring of the transaction itself. Examples of such credit support arising out of the structure of the transaction include the issue of senior and subordinated securities (e.g., the issuance of securities by an SPV in multiple classes or “tranches,” with one or more classes being senior to other subordinated classes as to the payment of principal and interest, with the result that defaults on the underlying mortgage loans are borne first by the holders of the subordinated class); creation of “reserve funds” (in which case cash or investments, sometimes funded from a portion of the payments on the underlying mortgage loans, are held in reserve against future losses); and “overcollateralization” (in which case the scheduled payments on, or the principal amount of, the underlying mortgage loans exceeds that required to make payment on the securities and pay any servicing or other fees). However, there can be no guarantee that credit enhancements, if any, will be sufficient to prevent losses in the event of defaults on the underlying mortgage loans. In addition, MBS that are issued by private issuers are not subject to the underwriting requirements for the underlying mortgages that are applicable to those MBS that have a government or government-sponsored entity guarantee. As a result, the mortgage loans underlying private MBS may, and frequently do, have less favorable collateral, credit risk or other underwriting characteristics than government or government-sponsored MBS and have wider variances in a number of terms including interest rate, term, size, purpose and borrower characteristics. Privately issued pools more frequently include second mortgages,

47

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2013

high loan-to-value mortgages and manufactured housing loans. The coupon rates and maturities of the underlying mortgage loans in a private-label MBS pool may vary to a greater extent than those included in a government guaranteed pool, and the pool may include subprime mortgage loans.

Privately issued MBS are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, MBS held in the Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans.

Asset-Backed Securities

ABS may include MBS, loans, receivables or other assets. The value of the Fund’s ABS may be affected by, among other things, actual or perceived changes in interest rates, factors concerning the interests in and structure of the issuer or the originator of the receivables, the market’s assessment of the quality of underlying assets or actual or perceived changes in the credit worthiness of the individual borrowers, the originator, the servicing agent or the financial institution providing the credit support.

Payment of principal and interest may be largely dependent upon the cash flows generated by the assets backing the securities.

Rising or high interest rates tend to extend the duration of ABS, making them more volatile and more sensitive to changes in interest rates. The underlying assets are sometimes subject to prepayments which can shorten the security’s weighted average life and may lower its return. Defaults on loans underlying ABS have become an increasing risk for ABS that are secured by home equity loans related to sub-prime, Alt-A or nonconforming mortgage loans, especially in a declining residential real estate market.

ABS (other than MBS) present certain risks that are not presented by MBS. Primarily, these securities may not have the benefit of any security interest in the related assets. Credit card receivables are generally unsecured and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give such debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. There is the possibility that recoveries on repossessed collateral may not, in some cases, be available to support payments on these securities. ABS are often backed by a pool of assets representing the obligations of a number of different parties. To lessen the effect of failures by obligors on underlying assets to make payments, the securities may contain elements of credit support which fall into two categories: (i) liquidity protection, and (ii) protection against losses resulting from ultimate default by an obligor on the underlying assets. Liquidity protection refers to the provision of advances, generally by the entity administering the pool of assets, to ensure that the receipt of payments on the underlying pool occurs in a timely fashion. Protection against losses results from payment of the insurance obligations on at least a portion of the assets in the pool. This protection may be provided through guarantees, policies or letters of credit obtained by the issuer or sponsor from third parties, through various means of structuring the transaction or through a combination of such approaches. The Fund will not pay any additional or separate fees for credit support. The degree of credit support provided for each issue is generally based on historical information respecting the level of credit risk associated with the underlying assets.

Delinquency or loss in excess of that anticipated or failure of the credit support could adversely affect the return on an investment in such a security. The availability of ABS may be affected by legislative or regulatory developments. It is possible that such developments may require the Fund to dispose of any then existing holdings of such securities.

Short Sales

The Fund may enter into short sale transactions. A short sale is a transaction in which a Fund sells a security it does not own in anticipation of a decline in the market price of the security. Securities sold in short

48

Notes to Financial Statements

sale transactions and the interest payable on such securities, if any, are reflected as a liability on the Statements of Assets and Liabilities. A Fund is obligated to deliver the security at the market price at the time the short position is closed. The risk of loss on a short sale transaction is theoretically unlimited, because there is no limit to the cost of replacing the security sold short, whereas losses from purchase transactions cannot exceed the total amount invested. As of August 31, 2013, short positions were held by the Fund.

Master Agreements

The Fund is a party to International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreements”) with counterparties that govern transactions in over-the-counter derivative and foreign exchange contracts entered into by the Fund and those counterparties. The ISDA Master Agreements contain provisions for general obligations, representations, agreements, collateral and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement. Any election to terminate early could be material to the financial statements. Since different types of forward and OTC financial derivative transactions have different mechanics and are sometimes traded out of different legal entities of particular counterparty organization, each type of transaction may be covered by a different Master Agreement, resulting in the need for multiple agreements with a single counterparty. As the Master Agreements are specific to unique operations of different asset types, they allow a Fund to net its total exposure to a counterparty in the event of a default with respect to all the transactions governed under a single agreement with a counterparty.

Master Repurchase Agreements (“Master Repo Agreements”) govern transactions between a Fund and select counterparties. The Master Repo Agreements maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for Repurchase and Reverse Repurchase Agreements.

Master Securities Forward Transaction Agreements (“Master Forward Agreements”) govern the considerations and factors surrounding the settlement of certain forward settling transactions, such as delayed delivery or sale-buyback financing transactions by and between a Fund and select counterparties. The Master Forward Agreements maintain provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral.

5. Financial Derivative Instruments

The Fund may utilize derivative instruments to enhance return, hedge risk, gain efficient exposure to an asset class or to manage liquidity. When considering the Fund’s use of derivatives, it is important to note that the Fund does not use derivatives for the purpose of creating financial leverage.

Options Contracts

The Fund may write (1) call and put options on futures, swaps (“swaptions”), securities, commodities or currencies it owns or in which it may invest and (2) inflation-capped options. Writing put options tends to increase the Fund’s exposure to unfavorable movements of the underlying instrument in exchange for an upfront premium. Writing call options tends to decrease the Fund’s exposure to favorable movements of the underlying instrument in exchange for an upfront premium. When the Fund writes a call, put, or inflation-capped option, an amount equal to the premium received is recorded as a liability and subsequently marked to market to reflect the current value of the option written. The purpose of inflation-capped options is to protect the buyer from inflation erosion above a certain rate on a given notional exposure. A floor can be used to give downside protection to investments in inflation-linked products. These liabilities are reflected as written options outstanding on the Statement of Assets and Liabilities. Certain options may be written with premiums to be determined on a future date. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against amounts paid on the underlying futures, swap, security or currency transaction to

49

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2013

determine the realized gain or loss when the underlying transaction is sold. The Fund as a writer of an option has no control over whether the underlying instrument may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the instrument underlying the written option. There is the risk the Fund may not be able to enter into a closing transaction because of an illiquid market.

The Fund may also purchase put and call options. Purchasing call options tends to increase the Fund’s exposure to favorable movements of the underlying instrument in exchange for paying an upfront premium. Purchasing put options tends to decrease the Fund’s exposure to unfavorable movements of the underlying instrument. The Fund pays a premium which is included on the Fund’s Statement of Assets and Liabilities as an investment and subsequently marked to market to reflect the current value of the option. Premiums paid for purchasing options which expire are treated as realized losses. Certain options may be purchased with premiums to be determined on a future date. The premiums for these options are based upon implied volatility parameters at specified terms. The risk associated with purchasing put and call options is limited to the premium paid. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain or loss when the underlying transaction is sold.

Options

For the six months ended August 31, 2013, the Fund purchased/sold options primarily for return enhancement, hedging and exposing cash to markets.

The Fund’s options contracts outstanding fluctuate throughout the operating year as required to meet strategic requirements. The following table illustrates the quarterly volume of options contracts. For purpose of this disclosure, volume is measured by contracts outstanding at period end (in thousands).

	Average Purchased Option and Swaption Contracts Outstanding
For the Quarter Ended	May 31, 2013		August 31, 2013
Flexible Bond	$	38,168	$	20,632
	Average Written Option and Swaption Contracts Outstanding
For the Quarter Ended	May 31, 2013		August 31, 2013
Flexible Bond	$	59,514	$	45,648

Straddle Options

The Fund may enter into differing forms of straddle options. A straddle is an investment strategy that uses combinations of options that allow a Fund to profit based on the future price movements of the underlying security, regardless of the direction of those movements. A written straddle involves simultaneously writing a call option and a put option on the same security with the same strike price and expiration date. The written straddle increases in value when the underlying security price has little volatility before the expiration date. A purchased straddle involves simultaneously purchasing a call option and a put option on the same security with the same strike price and expiration date. The purchased straddle increases in value when the underlying security price has high volatility, regardless of direction, before the expiration date.

Swap Agreements

The Fund may invest in swap agreements. Swap agreements are privately negotiated agreements between the Fund and a counterparty to exchange at specified, future intervals. The Fund may enter into credit default, cross-currency, interest rate and other forms of swap agreements to manage its exposure to credit, currency, interest rate, and inflation risk. In connection with these agreements, securities or cash may be identified as collateral in accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default or bankruptcy/insolvency.

50

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2013

Swaps are marked to market daily based upon values from third party vendors or quotations from market makers to the extent available and the change in value, if any, is recorded as an unrealized gain or loss on the Statement of Assets and Liabilities. In the event that market quotes are not readily available and the swap cannot be valued pursuant to one of the valuation methods, the value of the swap will be determined in good faith by the Valuation Committee pursuant to procedures approved by the Board.

Payments received or made at the beginning of the measurement period are reflected as such on the Statement of Assets and Liabilities and represent payments made or received upon entering into the swap agreement to compensate for differences between the stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, interest rates, and other relevant factors). These upfront payments are recorded as realized gains or losses on the Statement of Operations upon termination or maturity of the swap. A liquidation payment received or made at the termination of the swap is recorded as realized gain or loss on the Statement of Operations. Net periodic payments received or paid by the Fund are included as part of realized gains or losses on the Statement of Operations.

Entering into these agreements involves, to varying degrees, elements of credit, market and documentation risk in excess of the amounts recognized on the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements and that there may be unfavorable changes in interest rates.

The Fund’s maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from the counterparty over the contract’s remaining life, to the extent that amount is positive. The risk is mitigated by having a master netting arrangement between the Fund and the counterparty and by the posting of collateral to the Fund to cover the Fund’s exposure to the counterparty.

Credit Default Swap Agreements

Credit default swap agreements involve one party making a stream of payments (referred to as the buyer of protection) to another party (the seller of protection) in exchange for the right to receive a specified return in the event of a default or other credit event for the referenced entity, obligation or index. As a seller of protection on credit default swap agreements, the Fund will generally receive from the buyer of protection a fixed rate of periodic premium throughout the term of the swap provided that there is no credit event. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure up to the notional amount of the swap.

If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. If the Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. Recovery values are estimated by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value.

Credit default swap agreements on corporate issues, sovereign issues of an emerging country or U.S. municipal issues involve one party making a stream of payments to another party in exchange for the right to

51

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2013

receive a specified return in the event of a default or other credit event. If a credit event occurs and cash settlement is not elected, a variety of other deliverable obligations may be delivered in lieu of the specific referenced obligation. The ability to deliver other obligations may result in a cheapest-to-deliver option (the buyer of protection’s right to choose the deliverable obligation with the lowest value following a credit event). The Fund may use credit default swaps on corporate issues, sovereign issues of an emerging country or U.S. municipal issues to provide a measure of protection against defaults of the issuers (i.e., to reduce risk where the Fund owns or has exposure to the referenced obligation) or to take an active long or short position with respect to the likelihood of a particular issuer’s default.

Credit default swap agreements on asset-backed securities involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a default or other credit event. Unlike credit default swaps on corporate issues, sovereign issues of an emerging country or U.S. municipal issues, deliverable obligations in most instances would be limited to the specific referenced obligation as performance for asset-backed securities can vary across deals. Prepayments, principal paydowns, and other writedown or loss events on the underlying mortgage loans will reduce the outstanding principal balance of the referenced obligation. These reductions may be temporary or permanent as defined under the terms of the swap agreement and the notional amount for the swap agreement will be adjusted by corresponding amounts. The Fund may use credit default swaps on asset-backed securities to provide a measure of protection against defaults of the referenced obligation that the Fund owns or to take an active long or short position with respect to the likelihood of a particular referenced obligation’s default that the Fund does not own.

Credit default swap agreements on credit indices involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a write-down, principal shortfall, interest shortfall or default of all or part of the referenced entities comprising the credit index. A credit index is a basket of credit instruments or exposures designed to be representative of some part of the credit market as a whole. These indices are made up of reference credits that are judged by a poll of dealers to be the most liquid entities in the credit default swap market based on the sector of the index. Components of the indices may include, but are not limited to, investment grade securities, high yield securities, asset-backed securities, emerging markets, and/or various credit ratings within each sector. Credit indices are traded using credit default swaps with standardized terms including a fixed spread and standard maturity dates. An index credit default swap references all the names in the index, and if there is a default, the credit event is settled based on that name’s weight in the index. The composition of the indices changes periodically, usually every six months, and for most indices, each name has an equal weight in the index. The Fund may use credit default swaps on credit indices to hedge a portfolio of credit default swaps or bonds, which is less expensive than it would be to buy many credit default swaps to achieve a similar effect. Credit default swaps on indices are benchmarks for protecting investors owning bonds against default, and traders use them to speculate on changes in credit quality.

Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues, sovereign issues of an emerging country or U.S. municipal issues as of period end are disclosed in the Notes to the Schedule of Investments and serve as an indicator of the current status of the payment/performance risk and represent a market participant view of the likelihood or risk of default for the underlying referent security to credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. For credit default swap agreements on asset-backed securities and credit indices, the quoted market prices and resulting values serve as the indicator of the current status of the payment/performance risk. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

The maximum potential amount of future payments (undiscounted) that the Fund as a seller of protection could be required to make under a credit default swap agreement would be an amount equal to the

notional amount of the agreement. Notional amounts of each individual credit default swap agreements outstanding as of August 31, 2013 for which the Fund is the seller of protection is disclosed in the Notes to the Schedule of Investments. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into by the Fund for the same referenced entity or entities.

For the six months ended August 31, 2013, the Fund entered into credit default swaps primarily for return enhancement hedging and exposing cash to markets.

The Fund’s credit default swap contract notional amounts outstanding fluctuate throughout the operating year as required to meet the strategic requirements. The following table illustrates the quarterly volume of credit default swap contracts. For the purpose of this disclosure, the volume is measured by the notional amounts outstanding at each quarter end (in thousands).

Interest Rate Swap Agreements

The Fund is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Because the Fund holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the Fund may enter into interest rate swap agreements. Interest rate swap agreements involve the exchange by the Fund with another party of their respective commitments to pay or receive interest with respect to the notional amount of principal.

Over-the Counter Swap Agreements

OTC financial derivative instruments such as forward currency contracts, options contracts, interest rate, and credit default swap agreements derive their value from underlying asset prices, indices, reference rates and other inputs or a combination of these factors. These instruments are valued using evaluated prices furnished by a pricing service selected by the Board. In certain cases, when a valuation is not readily available from a pricing service, the Fund’s Manager may provide a valuation. Depending on the instrument and the terms of the transaction, the value of the derivative instrument can be determined by a pricing service or Manager using a series of techniques, including simulation pricing models. The pricing models use inputs, such as issuer details, indices, spreads, interest rates, yield curves, dividends, and exchange rates, that are observed from actively quoted markets. Derivative instruments that use valuation techniques and inputs similar to those described above are normally categorized as Level 2 in the fair value hierarchy.

Inflation Swap Agreements

An inflation swap involves the use of inflation derivatives (or inflation-indexed derivatives) to transfer inflation risk from one party to another. The derivatives used may be over-the-counter or exchange-traded derivatives. Inflation swaps frequently include real rate swaps, such as asset swaps of inflation-indexed bonds. Inflation swaps are simply a linear form of such derivatives. Real rate swaps consist of the nominal interest swap rate minus the corresponding inflation swap.

In an inflation swap, one party pays a fixed rate on a notional principal amount, while the other party pays a floating rate linked to an inflation index, such as the Consumer Price Index (CPI). The party paying the floating rate pays the inflation adjusted rate multiplied by the notional principal amount.

There are three main types of inflation swap. In a standard interbank inflation-linked swap, or zero-coupon inflation-linked swap, cash flow is exchanged on the maturity date. This swap pays out the exact value of the cumulative inflation for a fixed capital sum over a determined period.

In a year-on-year inflation-linked swap, inflation is used on an annual basis rather than a cumulative one. Typically, an inflation swap is priced on a zero-coupon basis, with payment exchanged upon maturity. One party pays the compound fixed rate, while the other pays the actual inflation rate for the term of the swap. In Europe, inflation swaps are typically paid on a year-on-year basis where the year-on-year rate of change of the price index is paid. In the United States, payment is more typically on a month-on-month basis, although the inflation rate used is still the year-on-year rate.

In an inflation-linked income swap two cash flows are exchanged, each of which follows the inflation index. One party pays a fixed inflation increase annually over the period of the contract. The other party pays the actual inflation over the period of the contract. The swap itself consists of a series of zero-coupon swaps. Other traded inflation derivatives include caps, floors, and straddles, which are usually priced against year-on-year swaps.

Forward Foreign Currency Contracts

The Fund may enter into forward foreign currency contracts to hedge the exchange rate risk on investment transactions or to hedge the value of the Fund’s securities denominated in foreign currencies. Forward foreign currency contracts are valued at the forward exchange rate prevailing on the day of valuation. The Fund bears the market risk that arises from changes in foreign exchange rates, and accordingly, the unrealized gain (loss) on these contracts is reflected in the accompanying financial statements. The Fund also bears the credit risk if the counterparty fails to perform under the contract.

For the six months ended August 31, 2013, the Fund entered into foreign currency exchange contracts primarily for return enhancement and hedging.

The Fund’s foreign currency contract notional dollar values outstanding fluctuate throughout the operating year as required to meet strategic requirements. The following tables illustrate the quarterly volume of foreign currency contracts. For the purpose of this disclosure, volume is measured by the amounts bought and sold in USD (in thousands).

Futures Contracts

Futures contracts are contracts to buy or sell a standard quantity of securities at a specified price on a future date. The Fund may enter into financial futures contracts as a method for keeping assets readily convertible to cash if needed to meet shareholder redemptions or for other needs while maintaining exposure to the stock or bond market, as applicable. The primary risks associated with the use of futures contracts are the possibility of illiquid markets or imperfect correlation between the values of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

Upon entering into a futures contract, the Fund is required to set aside or deposit with a broker an amount, termed the initial margin, which typically represents a portion of the face value of the futures contract. The Fund usually reflects this amount on the Schedule of Investments as a U.S. Treasury Bill held as collateral for futures contracts or as Cash deposited with broker on the Statement of Assets and Liabilities. Payments to and from the broker, known as variation margin, are required to be made on a daily basis as the price of the futures contract fluctuates. Changes in initial settlement values are accounted for as unrealized appreciation (depreciation) until the contracts are terminated, at which time realized gains and losses are recognized. Futures contracts are valued at the most recent settlement price established each day by the exchange on which they are traded.

For the six months ended August 31, 2013, the Fund entered into future contracts primarily for return enhancement, hedging and exposing cash to markets.

The Fund’s futures contracts outstanding fluctuate throughout the operating year as required to meet strategic requirements. The following table illustrates the quarterly volume of futures contracts. For purpose of this disclosure, volume is measured by contracts outstanding at period end.

6. Principal Risks

In the normal course of business the Portfolios trade financial instruments and enter into financial transactions where risk of potential loss exists. Security values fluctuate (market risk) and may decline due to factors affecting securities markets in general, particular industries represented in the securities markets or conditions specifically related to a particular company. Failure of the other party to a transaction to perform (credit risk), for example by not making principal and interest payments when due, reduces the value of the issuer’s debt and could reduce the Portfolios’ income. Similar to credit risk, the Portfolios may be exposed to counterparty risk, or the risk that an institution or other entity with which the Portfolios have unsettled or open transactions will fail to make required payments or otherwise comply with the terms of the instrument, transaction or contract. The potential loss could exceed the value of the financial assets recorded in the financial statements. Some of the Portfolios’ investments may be illiquid and the Portfolios may not be able to vary the portfolio investments in response to changes in economic and other conditions. If a Portfolio is required to liquidate all or a portion of its investments quickly, the Portfolio may realize significantly less than the value at which it previously recorded those investments.

Market Risks

The Fund’s investments in financial derivatives and other financial instruments expose the Fund to various risks such as, but not limited to, interest rate, foreign currency and equity risks.

Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates. As nominal interest rates rise, the value of certain fixed income securities held by the Fund is likely to decrease. A nominal interest rate can be described as the sum of a real interest rate and an expected inflation rate. Fixed income securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile than securities with shorter durations. Duration is useful primarily as a measure of the sensitivity of a fixed income’s market price to interest rate (i.e. yield) movements.

If the Fund invests directly in foreign currencies or in securities that trade in, and receive revenues in, foreign currencies, or in financial derivatives that provide exposure to foreign currencies, it will be subject to the risk that those currencies will decline in value relative to the base currency of the Fund, or, in the case of

56

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2013

hedging positions, that the Fund’s base currency will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. As a result, the Fund’s investments in foreign currency denominated securities may reduce the returns of the Fund.

The fair values of equities, such as common stocks and preferred securities or equity related investments such as futures and options, 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 investor sentiment generally. They may also decline due to factors which affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities and equity related investments generally have greater market price volatility than fixed income securities.

Credit and Counterparty Risks

The Fund will be exposed to credit risk on parties with whom it trades and will also bear the risk of settlement default. The Fund minimizes concentrations of credit risk by undertaking transactions with a large number of customers and counterparties on recognized and reputable exchanges. The Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a financial derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings.

Similar to credit risk, the Fund may be exposed to counterparty risk, or the risk that an institution or other entity with which the Fund has unsettled or open transactions will default. Financial assets, which potentially expose the Fund to counterparty risk, consist principally of cash due from counterparties and investments. Furthermore, to the extent that unpaid amounts owed to the Fund exceed a predetermined threshold agreed to with the counterparty, such counterparty shall advance collateral to the Fund in the form of cash or cash equivalents equal in value to the unpaid amount owed to the Fund. The Fund may invest such collateral in securities or other instruments and will typically pay interest to the counterparty on the collateral received. If the unpaid amount owed to the Fund subsequently falls, the Fund would be required to return to the counterparty all or a portion of the collateral previously advanced to the Fund

All transactions in listed securities are settled/paid for upon delivery using approved counterparties. The risk of default is considered minimal, as delivery of securities sold is only made once the Fund has received payment. Payment is made on a purchase once the securities have been delivered by the counterparty. The trade will fail if either party fails to meet its obligation.

The Fund is subject to various Master Agreements, which govern the terms of certain transactions with select counterparties. These Master Agreements reduce the counterparty risk associated with relevant transactions by specifying credit protection mechanisms and providing standardization that improves legal certainty. Since different types of forward and OTC derivative transactions have different mechanics and are sometimes traded out of different legal entities of a particular counterparty organization, each type of transaction may be covered by a different Master Agreement and result in the need for multiple agreements with a single counterparty. Therefore, exposure cannot be netted and collateralized across all types of transactions. Exposures can only be netted across transactions governed under the same Master Agreement with the same legal entity.

Master Agreements can also help limit counterparty risk by specifying collateral posting arrangements at pre-arranged exposure levels. Under the Master Agreements, collateral is routinely transferred if the total net exposure to certain transactions (net of existing collateral already in place) governed under the relevant master agreement with a counterparty in a given account exceeds a specified threshold, which typically ranges

Notes to Financial Statements

from zero to $250,000 depending on the counterparty and the type of Master Agreement. United States Treasury bills and US dollar cash are generally the preferred forms of collateral, although other forms of AAA rated paper may be used. The Fund’s overall exposure to counterparty risk can change substantially within a short period, as it is affected by each transaction subject to the relevant Master Agreement. Master Repurchase Agreements (“Master Repo Agreements”) govern transactions between the Fund and select counterparties. The Master Repo Agreements maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for Repurchase Agreements.

Master Securities Forward Transaction Agreements (“Master Forward Agreements”) govern the considerations and factors surrounding the settlement of certain purchases and sales made on a delayed-delivery basis by and between the Fund and select counterparties. The Master Forward Agreements maintain provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral.

International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreements”) govern OTC financial derivative transactions entered into by the Fund and those counterparties. The ISDA Master Agreements maintain provisions for general obligations, representations, agreements, collateral and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement. Any election to early terminate could be material to the financial statements. The fair value of OTC financial derivative transactions net of collateral received in or pledged by counterparty as of period end is disclosed in the Notes to the Schedule of Investments.

7. Federal Income and Excise Taxes

It is the policy of the Fund to qualify as a regulated investment company (“RIC”), by complying with all applicable provisions of Subchapter M of the Internal Revenue Code, as amended, and to make distribution of taxable income sufficient to relieve it from substantially all federal income and excise taxes. For federal income tax purposes, the Fund is treated as a single entity for the purpose of determining such qualification.

The Fund does not have any unrecognized tax benefits in the accompanying financial statements. The tax years for the periods ended August 31, 2011, 2012, and 2013, remain subject to examination by the Internal Revenue Service. If applicable, the Fund recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in “Other expense” on the Statement of Operations.

Dividends are categorized in accordance with income tax regulations which may treat certain transactions differently than U.S. GAAP. Accordingly, the character of distributions and composition of net assets for tax purposes may differ from those reflected in the accompanying financial statements.

The Fund may be subject to taxes imposed by countries in which it invests. Such taxes are generally based on returns of income earned or gains realized or repatriated. Taxes are accrued and applied to net investment income, net realized capital gains and net unrealized appreciation or depreciation, as applicable, as the income is earned or capital gains are recorded.

The tax character of distributions paid was as follows (in thousands):

	Year ended August 31,  2013		Year ended August 31, 2012
Distributions paid from:
Ordinary income*:
Institutional Class	$	699	$	447

Investor Class		411		—
A Class		210		—
C Class		93		—
Total distributions paid	$	3,599	$	1,000

* For tax purposes, short-term capital gains are considered ordinary income distributed.

As of August 31, 2013, the components of distributable earnings (deficit) on a tax basis were as follows (in thousands):

Cost basis of investments for federal income tax purposes	$	297,897
Unrealized appreciation		14,433
Unrealized depreciation		(21,304	)
Net unrealized appreciation (depreciation)		(6,871	)
Undistributed ordinary income		263
Accumulated long-term gain(loss)		852
Other temporary differences		(39	)
Distributable earnings (deficit)	$	(5,795	)

Financial reporting records are adjusted for permanent book/tax differences to reflect tax character. Financial records are not adjusted for temporary differences. The temporary differences between financial reporting and tax-basis reporting of unrealized appreciation or (depreciation) are attributable to the tax deferral of losses from wash sales and the realization for tax purposes of unrealized gain (losses) on certain derivative instruments.

Due to inherent differences in the recognition of income and expenses and realized gains(losses) under U.S. GAAP and federal tax regulations, permanent differences between book and tax reporting have been identified and appropriately reclassed on the Statement of Assets and Liabilities.

Accordingly, the following amounts represent current year permanent differences derived from foreign currency and income from publicly traded partnerships that have been reclassified as of August 31, 2013 (in thousands):

Paid-in-capital	$	—
Undistributed net investment income		1,806
Accumulated net realized gain(loss)		(1,807	)
Unrealized appreciation or (depreciation) of investments, futures contracts, option and swaption contracts andforeign currency translations		1

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “RIC MOD”) was enacted, which changed various technical rules governing the tax treatment of regulated investment companies. The changes are generally effective for taxable years beginning after the date of enactment. One of the more prominent changes addresses capital loss carryforwards. Under the RIC MOD, each Fund will be permitted to carry forward capital losses incurred in taxable years beginning after the date of enactment for an unlimited period. However, any losses incurred during those future taxable years will be required to be

59

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2013

utilized prior to the losses incurred in pre-enactment taxable years, which carry an expiration date. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital loss carryforwards will retain their character as either short-term or long-term capital losses rather than being considered all short-term as permitted under previous regulation.

Finally, the RIC MOD contains several provisions aimed at preserving the character of distributions made by a fiscal year registered investment company (“RIC”) during the portion of its taxable year ending after October 31 or December 31, reducing the circumstances under which a RIC might be required to file amended Forms 1099 to restate previously reported distributions. Except for the simplification provisions related to RIC qualification, the RIC MOD is effective for taxable years beginning after December 22, 2010. The provisions related to RIC qualification are effective for taxable years for which the extended due date of the tax return is after December 22, 2010.

The Fund does not have capital loss carryforwards as of August 31, 2013.

Disclosure Regarding the Board of Trustees’ Approval of the Management

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

At its May 29, 2013 meeting, the Board of Trustees (“Board”) considered the renewal of the Management Agreement between American Beacon Advisors, Inc. (“Manager”) and the American Beacon Funds (“Beacon Trust”) on behalf of each of their series (collectively, the “Funds”) and the renewal of each investment advisory agreement between the Manager and a subadvisor (each an “Investment Advisory Agreement”). The Management Agreement and the Investment Advisory Agreements are collectively referred to herein as the “Agreements.” In preparation for the Board’s consideration to renew and approve these Agreements, the Board and its Investment Committee undertook steps to gather and consider information furnished by the Manager, the subadvisors, Lipper, Inc. (“Lipper”) and Morningstar, Inc. (“Morningstar”). The Board, with the assistance of independent legal counsel, requested and received certain relevant information from the Manager and each subadvisor.

In addition, the Board’s Investment Committee worked with Lipper to obtain relevant comparative information regarding the performance, fees and expenses of the Funds. The Investment Committee, for the benefit of all Trustees, sponsored a separate meeting on May 10, 2013 to consider the information provided by Lipper. Further, the Board took into consideration information furnished for the Board’s review and consideration throughout the year at regular Board and Investment Committee meetings, as well as information specifically prepared in connection with the renewal process.

In connection with the Board’s consideration of the Management Agreement and each Investment Advisory Agreement, the Trustees received and evaluated such information as they deemed necessary. The information requested by the Board included, among other information, the following materials. For various reasons, a subadvisor may not have provided responses to each requested item. In these instances, the Board considered the materials that were received from such subadvisor. References herein to the “firm” refer to the Manager and/or each applicable subadvisor.

• a discussion of whether the Manager provides different types or levels of administrative and accounting related services to certain Funds;

• a description of the Manager’s distribution activities with respect to promoting sales of Fund shares, including any revenue sharing practices;

• a description of arrangements pursuant to which certain firms may make any direct or indirect payments to partially reimburse the Manager for its marketing or other expenses on behalf of the Funds;

• a description of the Manager’s securities lending practices and the fees received from such practices;

• a discussion of any rebate arrangements between the Manager and a service provider to the Funds pursuant to which the Manager receives direct or indirect benefits from the service provider;

• a description of the portfolio turnover rate for each Fund and, as applicable, each subadvisor to a Fund;

• a description of how expenses that are not readily identifiable to a particular Fund are allocated; and

• confirmation that the Manager complies with applicable CFTC and National Futures Association rules and requirements for applicable Funds and a discussion regarding whether, due to the Manager’s trading activities on behalf of other Funds, the Manager would need to register, or qualify for exclusion from registration, as a commodity pool operator or commodity trading advisor pursuant to the recent amendment to Rule 4.5 under the Commodity Exchange Act with respect to the Funds and, if so, whether the firm would so register or be exempt.

In connection with the Management Agreement and each Investment Advisory Agreement, the Board also obtained an analysis provided by Lipper that compared: (i) investment performance of each Fund versus comparable investment companies and appropriate indices; (ii) total Fund expenses of each Fund versus comparable mutual funds; and (iii) each Fund’s investment advisory fee rate versus comparable mutual funds. For certain Funds, the Board also considered information regarding the performance of the Manager and individual subadvisors with respect to their allocated portions of a Fund’s portfolio, net of management or subadvisory fees, as applicable, but not other Fund expenses. For each Fund with more than one class of shares, the class of shares used for comparative purposes was the class with the longest performance history, which in most cases was the Institutional Class. The Board also considered that the use of Institutional Class performance generally facilitates a meaningful comparison for expense and performance purposes.

Provided below is an overview of the primary factors the Trustees considered at the Investment Committee meeting on May 10, 2013 at which the Trustees reviewed the investment performance of the Manager and each subadvisor and the primary factors considered by the Board at its May 29, 2013 meeting at which the Board considered the renewal of the Management Agreement and Investment Advisory Agreements.

Disclosure Regarding the Board of Trustees’ Approval of the Management

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

The Board did not identify any particular information that was most relevant to its consideration to renew or approve each Agreement, and each Trustee may have afforded different weight to the various factors. Legal counsel to the independent Trustees provided the Board with a memorandum regarding its responsibilities pertaining to the renewal and approval of each Agreement. The memorandum explained the regulatory requirements surrounding the Trustees’ process for evaluating investment advisors and the terms of the contracts. Based on its evaluation, the Board unanimously concluded that the terms of each Agreement were reasonable and fair and that the renewal and approval of each Agreement was in the best interests of the Funds and their shareholders.

Considerations With Respect to the Renewal of the Management Agreement and Each Investment Advisory Agreement

In determining whether to renew the Management Agreement and each Investment Advisory Agreement on behalf of the Funds, the Trustees considered the best interests of each Fund separately. While the Management Agreement and the Investment Advisory Agreements for all of the Funds were considered at the May 29, 2013 meeting, the Board considered each Fund’s investment management and subadvisory relationships separately.

In each instance, the Board considered, among other things, the following factors: (1) the nature, extent and quality of the services provided; (2) the investment performance of a Fund and, as applicable, each subadvisor for a Fund; (3) the costs incurred by the Manager in rendering services to the Funds and its resulting profits or losses; (4) the extent to which economies of scale have been taken into account in setting each fee rate schedule; (5) whether fee rate levels reflect these economies of scale for the benefit of Fund investors; (6) comparisons of services and fee rates with contracts entered into by the Manager or a subadvisor or their affiliates with other clients (such as pension funds and other institutional funds); and (7) any other benefits derived or anticipated to be derived by the Manager or a subadvisor from their relationship with a Fund. The Trustees posed questions to various management personnel of the Manager regarding certain key aspects of the materials submitted in support of the renewal.

Nature, Extent and Quality of Services. With respect to the renewal of the Management Agreement, the Board considered, among other factors: each Fund’s long-term performance and the background and experience of key investment personnel at the Manager; the cost structure of the Funds; the Manager’s culture of compliance and support for compliance operations that reduce risks to the Funds; the Manager’s commitment to enhance the Funds’ product line and increase assets in the Funds; the Manager’s quality of services; the Manager’s active role in monitoring and, as appropriate, recommending additional or replacement subadvisors; the Manager’s commitment to training employees; and the Manager’s efforts to retain key employees and maintain staff levels.

With respect to the renewal of each Investment Advisory Agreement, the Trustees considered the level of staffing, quality, background and experience of each subadvisor’s investment personnel responsible for managing the Funds, the size of the subadvisor and the subadvisor’s ability to continue to attract and retain qualified investment personnel. The Board also considered the adequacy of the resources committed to the Funds by each subadvisor, and whether those resources were commensurate with the needs of the Funds and are sufficient to sustain appropriate levels of performance and compliance needs. In this regard, the Board considered the financial stability of each subadvisor. The Board also considered the subadvisors’ representations regarding their compliance programs and codes of ethics. Based on the foregoing information, the Board concluded that the nature, extent and quality of the management and advisory services provided by the Manager and each subadvisor were appropriate for each Fund and, thus, determined to renew the Management Agreement and the Investment Advisory Agreement for each Fund.

Investment Performance. The Board evaluated the comparative information provided by Lipper and the Manager regarding each Fund’s investment performance relative to its Lipper performance universe, Lipper performance group, and/or benchmark index(es). The Board considered the information provided by Lipper regarding its independent peer selection methodology to select all performance groups and universes. The Board also considered that the performance groups and universes selected by Lipper may not provide appropriate comparisons for each Fund. In addition, the Board considered the performance reports and discussions with management at Board and Committee meetings throughout the year. The Board also considered in each instance the Manager’s recommendation to continue to retain each subadvisor. A discussion regarding the Board’s considerations with respect to each Fund’s performance appears below under “Additional Considerations and Conclusions with Respect to Each Fund.”

Costs of the Services Provided to the Funds and the Profits Realized by the Manager from its Relationship with the Funds. In analyzing the cost of services and profitability of the Manager, the Board considered the revenues earned and the expenses incurred by the Manager. The profits or losses were noted at both an aggregate level for all Funds and at an individual Fund level, with some Funds being profitable for the Manager and with the Manager sustaining losses with respect to other Funds. Although the Board noted that, in certain cases, the fee rates paid by other clients of the Manager are lower than the fee rates paid by the Funds, the difference reflects the greater level of responsibility and regulatory requirements associated with managing the Funds.

The Board also noted that the Manager proposed to continue the expense waivers and reimbursements for certain Funds and classes that were in place during the last fiscal year. The Board further considered that with respect to each Fund, the Management Agreement provides for the Manager to receive a management fee comprised of an annualized fee that is retained by the Manager plus the amount payable by the Manager to a subadvisor. The Board also considered that the Manager receives service and administrative fees to compensate the Manager for providing administrative services to the Funds and to compensate third-party administrators and broker-dealers for services to Fund shareholders. In addition, the Board considered that the Manager receives management fees for overseeing the securities lending program on behalf of various Funds. The Board also noted that certain classes of the Funds maintain higher expense ratios in order to compensate third-party distributors.

In analyzing the cost of services for each subadvisor in connection with its investment advisory services to the Fund, the Board considered that, in many cases, the Manager has negotiated the lowest subadvisory fee rate a subadvisor charges for any comparable client

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

accounts. The Board did not request profitability data from the subadvisors because the Board did not view this data as imperative to its deliberations given the arm’s-length nature of the relationship between the Manager and the subadvisors with respect to the negotiation of subadvisory fee rates. In addition, the Board noted that subadvisors may not account for their profits on an account-by-account basis and, those that do, likely employ different methodologies in connection with these calculations.

Based on the foregoing information, the Board concluded that the profitability levels of the Manager were reasonable in light of the services performed by the Manager. A discussion regarding the Board’s considerations with respect to each Fund’s fee rates is set forth below under “Additional Considerations and Conclusions with Respect to Each Fund.”

Economies of Scale. In considering the reasonableness of the management and investment advisory fees rates, the Board considered whether economies of scale will be realized as the Funds grow and whether fee rate levels reflect these economies of scale for the benefit of Fund shareholders. In this regard, the Board considered that the Manager has negotiated breakpoints in many subadvisory fee rates. The Board also noted that, for purposes of determining the fee rates chargeable to the Funds, many subadvisors have agreed to take into account assets of AMR Corporation and its pension plans that are managed by the subadvisors. Thus, the Funds are able to receive lower effective fee rates.

In addition, the Board noted the Manager’s representation that many of the Funds benefit from economies of scale because comparably low fee rate levels are reflected in the current management and administration fee rates the Manager charges. The Board further noted the Manager’s representation that many of the Funds benefit from these comparably low fee rate levels despite not having yet reached an asset size at which economies of scale would traditionally be considered to exist, and the Manager’s belief that breakpoints are not appropriate at this time. Based on the foregoing information, the Board concluded that the Manager and subadvisor fee rate schedules for each Fund provide for a reasonable sharing of benefits from any economies of scale with the Funds.

Benefits Derived from the Relationship with the Funds. The Board considered the “fall-out” or ancillary benefits that accrue to the Manager and/or the subadvisors as a result of the advisory relationships with the Funds, including greater exposure in the marketplace with respect to the Manager’s or subadvisor’s investment process and expanding the level of assets under management by the Manager and the subadvisors.

In addition, the Manager noted that the Funds also derive benefits from their association with the Manager. Specifically, the Board noted the Manager’s representation that it provides services to most Funds at a lower than industry average cost. The Board considered that certain of the subadvisors reimburse the Manager for certain of its costs relating to distribution activities for the Funds. The Board also considered that the Funds did not pay commissions to any affiliated broker-dealer of the Manager or the relevant subadvisor during the most recent fiscal year ended December 31, 2012.

Based on the foregoing information, the Board concluded that the potential benefits accruing to the Manager and the subadvisors by virtue of their relationships with the Funds appear to be fair and reasonable.

Additional Considerations and Conclusions with Respect to Each Fund

The performance comparisons below were made versus each Fund’s Lipper performance universe median, Lipper performance group median and/or benchmark index. References below to each Fund’s Lipper performance group and Lipper performance universe are to the respective group or universe of comparable mutual funds included in the analysis provided by Lipper. A Lipper performance group consists of the Fund and a representative sample of funds with similar investment classifications and objectives as the Fund, as selected by Lipper. A Lipper performance universe is an expansion of the performance group, providing a broader view of performance across the Fund’s investment classification/objective and allowing for a more extensive comparison. In reviewing the performance, the Trustees viewed longer-term performance over a full market cycle, typically five years or longer, as the most important consideration, because relative performance over shorter periods may be significantly impacted by market or economic events that do not reflect manager skill.

The expense comparisons below were made versus each Fund’s Lipper expense universe median and Lipper expense group median. References below to each Fund’s expense group and expense universe are to the respective group or universe of comparable mutual funds included in the analysis by Lipper. A Lipper expense group consists of the Fund and a representative sample of funds with similar operating structures, as selected by Lipper. A Lipper expense universe includes all funds in the investment classification/objective with a similar load type to the share class of the Fund included in the Lipper comparative information and provides a broader view of expenses across the Fund’s investment classification/objective. The Trustees also considered a Fund’s Morningstar fee level category. In reviewing expenses, the Trustees considered the positive impact of fee waivers where applicable and the Manager’s agreement to continue the fee waivers. In addition, information regarding the use of soft dollars was requested from the Manager and all subadvisors and was considered by the Trustees.

Additional Considerations and Conclusions with Respect to the American Beacon Flexible Bond Fund

In considering the renewal of the Management Agreement for the American Beacon Flexible Bond Fund, the Trustees considered the following additional factors: (1) the American Beacon Flexible Bond Fund outperformed the Lipper performance universe median and Lipper performance group median for the one-year period ended March 31, 2013; (2) the expense ratio of the Institutional Class of the Fund was lower than the median of its Lipper expense universe and Lipper expense group; and (3) the Institutional Class of the Fund was categorized by Morningstar as having an average expense ratio.

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

In considering the renewal of the Investment Advisory Agreements with Brandywine Global Investment Management, LLC (“Brandywine”), GAM International Management LTD. (“GAM”) and Pacific Investment Management Company, LLC (“PIMCO”), the Trustees considered the following additional factors: (1) Brandywine, GAM and PIMCO each outperformed the Lipper performance universe median for the one-year period ended March 31, 2013; (2) representations by each subadvisor regarding fee rates charged by the subadvisor to other comparable clients; and (3) the Manager’s recommendation to continue to retain each subadvisor.

Based on these and other considerations, the Trustees: (1) concluded that the fees paid to the Manager and the subadvisors under the Agreements are fair and reasonable; (2) determined that the American Beacon Flexible Bond Fund and its shareholders would benefit from the Manager’s and subadvisors’ continued management of the Fund; and (3) approved the renewal of the Management and Investment Advisory Agreements with respect to the American Beacon Flexible Bond Fund.

Zebra Global Equity and Zebra Small Cap Equity Funds

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. At times, certain securities may have limited marketability and may be difficult to sell. The Fund may invest in futures contracts which are a type of derivative investment. Investing in derivatives could result in losing more than the amount invested. Investing in foreign securities entails additional risk not associated with domestic securities, such as currency fluctuations, economic and political instability and differences in accounting standards. Zebra Small Cap Equity Fund may participate in a securities lending program.

The London Company Income Equity Fund

The Fund’s primary risks include focused holdings risk, interest rate risk, small and medium capitalization risk, foreign exposure risk, future contracts risk, dividend risk and credit risk. These risks may expose the Fund’s investments to greater price fluctuations than the market as a whole. Because the Fund is a focused portfolio of fewer companies, the increase or decrease of the value of a single stock may have a greater impact on the Fund’s NAV and total return when compared to other diversified funds. Investing in debt securities entails interest rate risk, which is the risk that debt securities will decrease in value with increases in market interest rates. 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. Investing in foreign equities entails additional risk not associated with domestic equities, such as currency fluctuations, economic and political instability and differences in accounting standards. The Fund may invest in futures contracts which are a type of derivative investment. Investing in derivatives could result in losing more than the amount invested. Investing in dividend-paying stocks entails dividend risk, which is the risk that a stock may not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks. Credit risk is the risk that the decline in an issuer’s credit rating may have an adverse impact on the value of that security.

SiM High Yield Opportunities Fund

This Fund typically invests in a variety of domestic and foreign high-yield, high risk securities. Investing in high-yield securities involves additional risks when compared to investing in investment-grade securities. These include a greater risk of default or bankruptcy and an increased sensitivity to financial difficulties or changes in interest rates. These risks are enhanced through the use of derivative securities, foreign and emerging markets securities.

Please see the prospectus for a more complete discussion of the risks of investing in these Funds.

Any opinions herein, including forecasts, reflect our judgment as of the end of the reporting period and are subject to change. Each advisor’s strategies and the Fund’s portfolio composition will change depending on economic and market conditions. This report is not a complete analysis of market conditions and therefore, should not be relied upon as investment advice.

American Beacon Funds August 31, 2013

Dear Shareholders,

Over the past 12 months, world markets continued to steadily climb a wall of worry. Despite concerns over a possible tapering of the U.S. Federal Reserve quantitative easing program, uncertainty over Federal Reserve Chairman Ben Bernanke’s replacement, a possible slowdown in China and the looming political battle over the U.S. debt ceiling, American Beacon’s actively managed funds posted strong gains.

For the 12-month period ended August 31, 2013:

The American Beacon The London Company Income Equity Fund (Investor Class) returned 15.14%.

The American Beacon Zebra Global Equity Fund (Investor Class) returned 16.32%.

Domestic Equity Market Overview

August 31, 2013 (Unaudited)

U.S. stocks posted strong results for the year ended August 31, 2013. An improving economy, low interest rates and recovering investor sentiment helped drive the market higher, as did the Federal Reserve’s continued quantitative easing program. Despite a hiccup in the middle of the period under review, when Federal Reserve Chairman Ben Bernanke introduced the notion of the “taper,” the rally was as broad-based as it was strong.

The 12-month period began with a rough patch. During the fourth quarter of 2012, only half of the ten sectors of the S&P 500 Index earned positive total returns, led by Financials at 5.9% and Industrials at 3.7%. The bottom sectors were Telecommunications, which lost 6.0%, and Information Technology, which lost 5.7%. Large-cap and large-cap growth stocks each had negative returns of -0.4% and -1.3%, respectively, as measured by the S&P 500 Index and the Russell 1000 Growth Index. The one bright spot was small-cap value stocks, represented by the Russell 2000 Value Index, which was up 3.2% during the fourth quarter of 2012.

The early part of 2013, however, proved to be exceptionally strong. At the end of the first quarter, on March 28, the S&P 500 Index finally surpassed its pre-crash high, closing at its highest mark since October 2007. The index gained 14.1% between the first of the year and May 21. On that day, though, Federal Reserve chairman Ben Bernanke indicated that the Fed’s asset-purchasing program would be coming to an end at some point, the first mention of the so-called taper, sending shock waves through the market. The S&P 500 Index dropped more than 5% in the space of a month.

Subsequently, June broke a seven-month winning streak for both the S&P 500 and the Nasdaq indexes, but the market quickly found its footing and began to rally at that point. Even with the taper-induced drop-off, by the end of June, the S&P 500 Index had posted its best first half of any year since 1998.

The overall U.S. economy showed strength as well. Coming off a disappointing fourth quarter of 2012, in which the gross domestic product (GDP) grew at just 0.4%, GDP bounced back to 1.1% growth in the first quarter of 2013 and 2.5% in the second quarter. Unemployment continued to drop in a slow but mostly steady fashion, from 8.1% in August 2012 to 7.3% in August 2013. Although this was good news for the larger economy, the falling unemployment rate made some investors nervous, because Chairman Bernanke has indicated that the economy would be healthy enough for him to end quantitative easing once the unemployment rate reached 7.0%.

For the 12 months that ended August 31, 2013, the S&P 500 Index returned 18.7%. Value stocks showed an even stronger performance, with the Russell 1000 Value Index returning 23.1% over the same period. Small-cap stocks were the strongest of all as the Russell 2000 Index returned 26.3% over the 12-month period.

One cannot directly invest in an index.

4. The total annual Fund operating expense ratio set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A and C Class shares was 1.25%, 1.35%, 1.63%, 1.75%, and 2.50%, respectively. The expense ratios above may vary from the expense ratios presented in other sections of this report that are based on expenses incurred during the period covered by this report.

The Fund’s underperformance relative to the Index was largely driven by weaker stock selection. To a lesser extent, the Fund’s sector allocation versus the Index also proved to be unfavorable to performance.

Weak stock selection in the Consumer Staples, Information Technology and Financials sectors proved to be the largest detractors from relative returns. Despite the Fund’s aggregate holdings in these economic sectors producing positive absolute returns, these securities lagged the gains generated by those in the Index.

Within the Consumer Staples sector, the Fund was negatively impacted by holding Coca Cola (up 4.1%). International Business Machines (down 6.5%) hindered relative returns within the Information Technology sector while Hatteras Financial Corporation (down 29.3%) was the primary driver of the negative impact within the Financials sector.

Several of the holdings within the Materials sector were bright spots for returns. In particular, MeadWestvaco (up 27.1%) displayed strong results.

Given the Fund’s portfolio construction approach and high conviction weightings across securities, the Fund’s over or underweight positioning relative to the economic sectors will typically have less of an impact on relative returns.

However, the Fund was slightly hampered by its sector positioning. Specifically, maintaining an overweight to the Materials and Utilities sectors impeded results as those sectors trailed the overall market. Additionally, underweighting the strong Financials sector (up 30.1%) also negatively impacted returns. Offsetting some of the headwinds from the Fund’s overall positioning was an underweight to the Energy sector (up 12.0%) as it was one of the weaker performers.

The sub-advisor’s investment process focuses on downside protection, current income and total return appreciation.

Global Equity Market Overview

August 31, 2013 (Unaudited)

During the 12-month period ended August 31, 2013, the global equity markets moved steadily higher, with the exception for two moderate pullbacks that occurred from mid-October through mid-November of 2012 and then again from mid-May 2013 through June 2013. The primary reason for this steady market rise was a consistent set of central bank policies across developed markets, with the U.S. Federal Reserve Bank in the lead. These policies kept interest rates low and encouraged investors to take on risk in equities.

Japan’s stock market was the pace-setter for the rest of the developed world after the election of Shinzo Abe in late 2012 and the subsequent implementation of an aggressive monetary policy. Over the 12 months under review, the Tokyo Stock Exchange’s index, TOPIX, rose 23%, outpacing every other developed market. Japan was hardly alone, though. Every country and region represented in the MSCI World Index was positive (when measured in U.S. dollars) between September 2012 and August 2013.

While receiving somewhat less attention, Europe’s emergence from recession was also a key element in boosting investor confidence. After six quarters in which the eurozone economy had contracted - the longest recession since the adoption of the euro - Europe finally began to show growth again in the second quarter of 2013. Germany and France continued to lead the European economy with second-quarter economic growth of 0.7% and 0.5%, respectively.

With all these economic tailwinds, it was a strong period for the stock markets in the developed world. The MSCI EAFE Index rose by 18.7% in the 12 months ended August 31, 2013.

In keeping with long-term historical trends, small-cap stocks outperformed large-cap stocks. The MSCI Global Small Cap Index gained approximately 23.5% versus 18.3% for the MSCI World Index, which represents large-cap stocks. In the U.S., the Russell 2000 small-cap index outperformed the Russell 1000 large-cap index by more than five percentage points from September 2012 through August 2013.

In the latter part of the period, stocks with higher dividend yields underperformed as interest rates spiked higher, albeit from very low levels. And as often happens in a “risk on” environment, the sector gains were led by Consumer Discretionary stocks.

The Energy and Materials sectors were the weakest performers as the fear of inflation remained subdued, Chinese growth rates were lowered, and raw materials prices, like coal and industrial metals, were unchanged to lower. China’s rapid growth over the previous decade had created a boom in raw materials; as recently as 2011, China alone was consuming 40% of the world’s copper, and China accounted for 60% of the growth in the world’s oil demand between 2003 and 2012. Global economies and markets are still adjusting to that slowdown.

Among individual stocks in the MSCI World Index, there was a preponderance of mining and natural resource stocks in the bottom-performing decile. Reviewing top performers, there was less consistency but there were several Japanese firms along with U.S. consumer products and retail firms.

An underweight in Information Technology, the worst performing sector in the Russell 1000 Index,

contributed more than 75 basis points (0.75%) to performance relative to the Russell 1000 Index through sector allocation. An overweight in Financials, the best performing sector in the Russell 1000 Index, added approximately 55 basis points (0.55%) to relative performance.

From a stock selection standpoint, the Fund’s holdings in the Materials and Information Technology sectors added the most relative value. Companies in the Materials sector that had the greatest impact on performance were Southern Copper (up 25.8%) and PPG Industries (up 24.3%). Not owning DuPont De Nemours, which was down 8.7% in the Russell 1000 Index, also contributed to relative performance. In the Information Technology sector, not owning Apple, which was down 19.6% in the Russell 1000 Index, contributed to the Fund’s relative performance. The aforementioned good performance was somewhat offset by poor stock selection in the Financials sector which detracted approximately 45 basis points (0.45%) from performance. In the Financials sector, not owning Bank of America, Citigroup and JP Morgan Chase which were up 45.6%, 33.2% and 19.3%, respectively, in the Russell 1000 Index detracted relative value.

For the eight months ended August 31, 2013, the Fund returned 13.81% before expenses, outperforming the MSCI World Index return of 11.71%. The Fund outperformed the MSCI World Index through security selection as sector allocation detracted value relative to the benchmark. The Fund’s holdings within the Information Technology and Industrials sectors contributed most to excess performance. In the Information Technology sector, Western Digital (up 65.9%) and Activision Blizzard (up 54.9%) were the largest contributors. Not owning Apple, which was down 6.9% in the Index, also added relative value. Central Japan Railway (up 47.1%), Toto Ltd. (up 57.0%) and Northrop Grumman (up 41.2%) contributed to the Fund’s returns in the Industrials sector.

Overweight positions in the Information Technology and Utilities sectors detracted from the Fund’s performance relative to the benchmark through sector allocation. From a country perspective, the Fund’s U.S. based companies were the largest contributors to returns.

The sub-advisor continues to focus on uncovering opportunities by investing in a portfolio of securities that are generally less popular with investors but nevertheless have strong fundamental

characteristics. At the same time, the portfolio will be underweight stocks that are heavily followed but have weak fundamentals. This contrarian style has tended to result in a portfolio with very good risk-adjusted returns over time. Even though the strategy does not explicitly seek out low-beta stocks, a by-product of the investment process is often a realized beta of less than 1. Beta is a measure of the Fund’s systematic risk compared to the Index. For example, a beta of 0.90 would indicate that the Fund is expected to provide a 10% lower return when the Index increases and a 10% better return when the Index decreases.

For the twelve month period, the daily beta of the Fund versus the indices was 0.95. In turn, the Fund exhibited good downside capture characteristics. As an illustration, in the twelve months ending August 31, 2013, looking at both the Russell 1000 Index (September - December) and MSCI World Index (January - August), together they were down on 113 days. The Fund outperformed the indices on 64 of those days (57% of the time). The average outperformance by the Fund on those down days was one basis point. Consequently much of the excess performance during the period was driven by this reduced downside capture. The sub-advisor’s strategy, and its resulting characteristics, should benefit the Fund’s performance over the longer term.

5. The total annual Fund operating expense ratio set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A and C Class shares was 3.23%, 3.44%, 3.65%, 3.76%, and 4.53% respectively. The expense ratios above may vary from the expense ratios presented in other sections of this report that are based on expenses incurred during the period covered by this report.

The Fund outperformed the Index primarily due to good stock selection, and to a lesser extent, through sector allocation. From a stock selection standpoint, holdings in the Industrials, Financials and Consumer Discretionary sectors contributed most to excess performance. In the Industrials sector, Bridgepoint Education (up 64.9%), Republic Airways (up 163.9%) and Education Management (up 161.4%) were the largest contributors. Generac Holdings (up 63.7%), Nelnet (up 50.0%) and Encore Capital Group (up 50.7%) had the largest impact to relative performance in the Financials sector. In the Consumer Discretionary sector, Dorman Products (up 77.4%) and Sinclair Broadcast Group (up 144.3%) added the most relative value. The aforementioned good performance was somewhat offset by poor stock selection in the Health Care sector. Select Medical Holdings (down 2.6%) and Orthofix International (down 48.2%) were the largest detractors in the Health Care sector. Not owning Aegerion Pharmaceuticals, which was up 522.7% in the Index, also detracted from the Fund’s performance.

Performance Overview

August 31, 2013 (Unaudited)

The Fund’s overweight position in Industrials and Consumer Staples, two of the better performing sectors in the Index, contributed approximately 25 basis points (0.25%) each to performance through sector allocation.

The sub-advisor continues to focus on uncovering opportunities by investing in a portfolio of securities that are generally less popular with investors but nevertheless have strong fundamental characteristics. At the same time, the portfolio will be underweight stocks that are heavily followed but have weak fundamentals. This contrarian style has tended to result in a portfolio with very good risk-adjusted returns over time. Even though the strategy does not explicitly seek out low-beta stocks, a by-product of the investment process is often a realized beta of less than 1. Beta is a measure of the Fund’s systematic risk compared to the Index. For example, a beta of 0.90 would indicate that the Fund is expected to provide a 10% lower return when the Index increases and a 10% better return when the Index decreases.

For the twelve month period, the daily beta of the Fund versus the Index was 0.95. In turn, the Fund exhibited good downside capture characteristics. As an illustration, in the twelve months ending August 31, 2013, the Index was down on 105 days. The Fund outperformed the Index on 65 of those days (62% of the time). Consequently, much of the excess performance generated by the Fund during the period was driven by this reduced downside capture. The sub-advisor’s strategy, and its resulting characteristics, should benefit the Fund’s performance over the longer term.

High Yield Bond Market Overview

August 31, 2013 (Unaudited)

For the 12 months from September 2012 through August 2013, there were two distinct phases for the high yield market and for fixed-income in general.

The first part, from August 2012 through April 2013, was characterized by Treasury rates that moved in a muted up-and-down pattern coming off the August 2012 lows. In the U.S., the economic news was mixed but clearly leaned positive, and the tail risk from Europe was greatly reduced. During that period, the high yield spread tightened to reach a post-recession low of 423 basis points (4.23%) over Treasurys on May 10. The high yield market over this period produced a return of 9.70% for those eight months, as represented by the BofA Merrill Lynch U.S. High Yield Master II Index.

In May, the Federal Reserve initiated a new phase for the fixed-income markets when it discussed the possible future tapering of its quantitative easing program. Despite all the positive economic data, this caused bond investors to head for the exits. In June, roughly $60 billion flowed out of all bond funds – the largest monthly fund outflow ever, for either equity or bonds.

This pushed rates up sharply from the “artificially” low levels engineered by the Fed. Five-year Treasury rates rose almost 100 basis points (1.00%) from April to August. The return for the BofA Merrill Lynch U.S. High Yield Master II Index was a negative 1.94% for the period, with a price return of negative 4.26% and an income return of 2.32%. Other fixed-income investments were similarly challenged: The total return for the five-year Treasury was down 3.55% for the period, investment-grade bonds as measured by the BofA Merrill Lynch U.S. Corporates 1-10 Year Index were down 3.37%, and dollar-denominated emerging market corporates as measured by the BofA Merrill Lynch High Yield U.S. Emerging Markets Corporate Plus Index were down 5.89%.

Ordinarily, an improving economic outlook would cause high yield spreads to tighten, but the outflow of funds initially overwhelmed the high yield market, and spreads widened to 534 basis points, up 111 basis points from the May 10 lows. Subsequently, as the panic subsided, spreads tightened again after June and finished August at 474 basis points.

Over the period in review, lower quality outperformed because default rates were low and higher quality is generally more sensitive to interest rates. Single-B issues outperformed BB issues by more than 400 basis points (4.00%), and CCC outperformed B by more than 600 basis points (6.00%). From a sector standpoint there was no general theme of either underperformance or outperformance. For the year ended August 31, 2013, the BofA Merrill Lynch U.S. High Yield Master II Index returned 7.55%.

4. The total annual Fund operating expense ratio set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A, and C Class shares was 1.06%, 1.09%, 1.23%, 1.53%, and 2.26%, respectively. The expense ratios above may vary from the expense ratios presented in other sections of this report that are based on expenses incurred during the period covered by this report.

The Fund’s outperformance relative to the Index was largely driven by its strong issue selection within the various credit quality and sector categories. Conversely, the Fund’s relative weightings among credit quality and sector categories versus the Index were marginally negative.

From a credit quality perspective, issue selection in the B and CCC–rated credit categories was a major contributor to the Fund’s outperformance.

From a credit quality allocation perspective, maintaining a significant underweight to the higher rated securities within the non-investment grade universe (BB-rated credit group) and overweighting the lower rated securities within the non-investment grade universe (CCC-rated credit group) proved to be beneficial to the Fund’s relative returns.

From a sector standpoint, strong performance from issues in the Service, Consumer and Telecom sectors were significant drivers of the Fund’s excess returns versus the Index. However, some of those gains were modestly offset through trailing returns generated by the Fund’s holdings in the Agency, Electric and Foreign Sovereign sectors.

From a sector allocation perspective, the Fund benefited from underweighting the Energy (up 6.0%) and Manufacturing (up 7.2%) sectors. The Fund’s relative returns were hampered from

12

American Beacon SiM High Yield Opportunities Fund^SM

Performance Overview

underweighting the Finance sector (up 10.3%) and maintaining an overweight allocation to Foreign Sovereign securities (up 5.8%).

The Fund has the flexibility to utilize derivative instruments and will do so to enhance return, hedge risk, manage liquidity or to gain efficient exposure to an asset class. When considering the Fund’s use of derivatives, it is important to note that the Fund does not use derivatives for the purposes of creating financial leverage. During the period, the Fund experienced modest benefits from the use of derivatives such as swaps; however, investments in futures contracts offset those gains and were slightly negative.

The sub-advisor’s investment process of identifying long-term secular themes and seeking out of favor sectors through bottom-up fundamental research remains in place.

Fund Expenses

August 31, 2013 (Unaudited)

Fund Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs including sales charges (loads) on purchased shares and (2) ongoing costs, including management fees, administrative service fees, distribution (12b-1) fees, and other Fund expenses. The examples below are intended to help you understand the ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period in each Class and held for the entire period from March 1, 2013 through August 31, 2013.

Actual Expenses

The “Actual” lines of the table provide information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period. Shareholders of the Investor and Institutional Classes that invest in the Fund through an IRA or Roth IRA may be subject to a custodial IRA fee of $15 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $15 higher.

Hypothetical Example for Comparison Purposes

The “Hypothetical” lines of the table provide information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the Fund’s actual return). You may compare the ongoing costs of investing in the Fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. Shareholders of the Investor and Institutional Classes that invest in the Fund through an IRA or Roth IRA may be subject to a custodial IRA fee of $15 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $15 higher.

You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs charged by the Fund. Similarly, the expense examples for other funds do not reflect any transaction costs charged by those funds, such as sales charges (loads), redemption fees or exchange fees. Therefore, the “Hypothetical” lines of the table are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If you were subject to any transaction costs during the period, your costs would have been higher.

American Beacon Funds

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Beacon The London Company Income Equity Fund, American Beacon Zebra Global Equity Fund, American Beacon Zebra Small Cap Equity Fund, and American Beacon SiM High Yield Opportunities Fund:

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of the American Beacon The London Company Income Equity Fund, American Beacon Zebra Global Equity Fund, American Beacon Zebra Small Cap Equity Fund, and American Beacon SiM High Yield Opportunities Fund (four of the funds constituting the American Beacon Funds) (collectively, the “Funds”), as of August 31, 2013, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for the periods indicated therein. These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Funds’ internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of each Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2013, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the, American Beacon The London Company Income Equity Fund, American Beacon Zebra Global Equity Fund, American Beacon Zebra Small Cap Equity Fund, and American Beacon SiM High Yield Opportunities Fund at August 31, 2013, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

⁽¹⁾  If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

⁽²⁾  Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swaps agreements on corporate issues and sovereign issues of an emerging country as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽³⁾  The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

Notes to Financial Statements

August 31, 2013

1. Organization and Significant Accounting Policies

American Beacon Funds (the “Trust”), which is comprised of twenty-four Funds, is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company. These financial statements and notes to the financial statements relate to the American Beacon The London Company Income Equity Fund, the American Beacon Zebra Global Equity Fund, the American Beacon Zebra Small Cap Equity Fund, and the American Beacon SiM High Yield Opportunities Fund (each a “Fund” and collectively, the “Funds”), each a series of the Trust. Prior to December 31, 2012, the American Beacon Zebra Global Equity Fund was known as the American Beacon Zebra Large Cap Equity Fund.

American Beacon Advisors, Inc. (the “Manager”) is a wholly-owned subsidiary of Lighthouse Holdings, Inc. and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services to the Trust and other investors.

Class Disclosure

The Retirement Classes of the American Beacon Zebra Global Equity and American Beacon Zebra Small Cap Equity Funds were closed on March 13, 2013.

Each Fund has multiple classes of shares designed to meet the needs of different groups of investors. The following table sets forth the differences amongst the classes:

Class:	Offered to:
Institutional Class	Investors making an initial investment of $250,000
Y Class	Investors making an initial investment of $100,000
Investor Class	Individual investors investing directly or through an intermediary
A Class	General public and investors investing through an intermediary with applicable sales charges
C Class	General public and investors investing through an intermediary with applicable sales charges

Each class offered by the Trust has equal rights as to assets and voting privileges. Income and non-class specific expenses are allocated daily to each class on the basis of the relative net assets. Realized and unrealized capital gains and losses of each class are allocated daily based on the relative net assets of each class of the respective Fund. Class specific expenses, where applicable, currently include administrative service fees, service fees and distribution fees and vary amongst the classes as described more fully in Note 2.

New Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities. The amendments in the ASU enhance disclosures about offsetting of financial assets and liabilities to enable investors to understand the effect of these arrangements on a fund’s financial position. In January 2013, FASB issued ASU No. 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. The amendments in ASU No. 2013-01 clarify the scope of disclosures required by ASU No. 2011-11. These ASUs are effective for annual periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Funds believes the adoption of these ASUs will not have a material impact on its financial statement disclosures.

2. Transactions with Affiliates

Management Agreement

The Trust and the Manager are parties to a Management Agreement that obligates the Manager to provide or oversee the provision of all investment advisory, fund management, and securities lending services.

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2013

Investment assets of the Funds are managed by investment advisors which have entered into separate investment advisory agreements with the Manager. As compensation for performing the duties required under the Management Agreement, the Manager receives from the Funds an annualized fee equal to 0.05% of the average daily net assets plus amounts paid by the Manager to the unaffiliated investment advisors hired by the Manager to direct investment activities for the Funds. Management fees paid by the Funds during the year ended August 31, 2013 were as follows (dollars in thousands):

Fund	Management Fee Rate			Management Fee		Amounts paid to Investment Advisors		Net Amounts Retained by Manager
The London Company Income Equity		0.42	%	$	190	$	168	$	22
Zebra Global Equity		0.40	%		38		33		5
Zebra Small Cap Equity		0.57	%		41		37		4
SiM High Yield Opportunities		0.48	%		2,135		1,914		221

Administrative Services Agreement

The Manager and the Trust entered into an Administrative Services Agreement which obligates the Manager to provide or oversee administrative services to the Funds. As compensation for performing the duties required under the Administrative Services Agreement, the Manager receives an annualized fee of 0.30% of the average daily net assets of the Institutional, Y, and Investor Classes of the Funds and 0.40% of the average daily net assets of the A and C Classes of the Funds.

Distribution Plans

The Funds, except for the A and C Classes of the Funds, have adopted a “defensive” Distribution Plan (the “Plan”) in accordance with Rule 12b-1 under the Act, pursuant to which no separate fees may be charged to the Funds for distribution purposes. However, the Plan authorizes the management and administrative service fees received by the Manager and the investment advisor hired by the Manager to be used for distribution purposes. Under this Plan, the Funds do not intend to compensate the Manager or any other party, either directly or indirectly, for the distribution of the Funds’ shares.

Separate Distribution Plans (the “Distribution Plans”) have been adopted pursuant to Rule 12b-1 under the Act for the A and C Classes of the Funds. Under the Distribution Plans, as compensation for distribution assistance, the Manager receives an annual fee of 0.25% of the average daily net assets of the A Classes and 1.00% of the average daily net assets of the C Classes of each Fund. The fee will be payable without regard to whether the amount of the fee is more or less than the actual expenses incurred in a particular month by the Manager for distribution assistance.

Service Plans

The Manager and the Trust entered into Service Plans that obligate the Manager to oversee additional shareholder servicing of the Y, Investor, A, and C Classes. As compensation for performing the duties required under the Service Plans, the Manager receives 0.10% of the average daily net assets of Y Class, 0.15% of the average daily net assets of the A and C Classes, and up to 0.375% of the average daily net assets of the Investor Class of the Funds.

Interfund Lending Program

Pursuant to an exemptive order issued by the Securities and Exchange Commission (“SEC”), the Funds, along with other registered investment companies having management contracts with the Manager, may participate in an interfund lending program. This program provides an alternative credit facility allowing the Funds to borrow from other participating Funds. During the year ended August 31, 2013, the Zebra Global Equity Fund borrowed on average $244,310 for 12 days at an average equity rate of 0.78% with interest charges of $64, and the SiM High Yield Opportunities Fund borrowed on average $4,416,782 for 14 days at an average rate of 0.76% with interest charges of $1,294.

Expense Reimbursement Plan

The Manager contractually agreed to reimburse the following Funds to the extent that total annual fund operating expenses exceeded the Funds’ expense cap. For the period ended August 31, 2013, the Manager waived or reimbursed expenses as follows:

Fund	Class	Expense Cap			Reimbursed or (Recouped) Expenses			Expiration of Reimbursed Expenses
The London Company Income Equity	Institutional		0.79	%	$	85,612			2016
The London Company Income Equity	Y		0.89	%		15,702			2016
The London Company Income Equity	Investor		1.17	%		18,643			2016
The London Company Income Equity	A		1.29	%		15,001			2016

SiM High Yield Opportunities	A		1.34	%		41,192			2016
SiM High Yield Opportunities	C		2.09	%		29,895			2016

Of these amounts $8,532, $1,435, and $28,619 was receivable from the Manager for the Zebra Global Equity, Zebra Small Cap Equity, and SiM High Yield Opportunities Funds, respectively, at August 31, 2013. The Funds have adopted an Expense Reimbursement Plan whereby the Manager may seek repayment of fees waived or expenses reimbursed for a period of up to three years. However, reimbursement will occur only if the Class’s average net assets have grown or expenses have declined sufficiently to allow reimbursement without causing its expense ratio to exceed the previously agreed upon contractual expense limit. The reimbursed expenses listed above will expire in 2016. The carryover of excess expenses potentially reimbursable to the Manager are as follows:

Fund	Recovered Expenses			Excess Expense Carryover		Expiration of Reimbursed Expenses
The London Company Income Equity	$	—		$	117,605		2015
Zebra Global Equity		—			93,890		2014
Zebra Global Equity		—			166,541		2015
Zebra Small Cap Equity		—			100,737		2014
Zebra Small Cap Equity		—			155,632		2015
SiM High Yield Opportunities		(12,829	)		113,633		2014
SiM High Yield Opportunities		(23.919	)		136,702		2015

The Manager recouped $43,381 from the Investor Class of the SiM High Yield Opportunities Fund during the year ended August 31, 2013 for the expenses that were set to expire August 31, 2014, 2015, and 2016. The other Funds have not recorded a liability for potential reimbursements, due to the current assessment that a reimbursement is unlikely.

Sales Commissions

The Funds’ distributor, Foreside Fund Services, LLC (“Foreside”), may receive a portion of A Class sales charges from broker dealers and it may be used to offset distribution related expenses. For the year ended

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2013

August 31, 2013, Foreside collected $30,492, $698, $1,024, and $105,067 in sales commissions from the the sale of A Class Shares for The London Company Income Equity, Zebra Global Equity, Zebra Small Cap Equity, and SiM High Yield Opportunities Funds, respectively.

A contingent deferred sales charge (“CDSC”) of 1.00% will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless waived as discussed in the Prospectus. Any applicable CDSC will be 1.00% of the lesser of the original purchase price or the value of the redemption of the Class C Shares redeemed. During the year ended August 31, 2013 the following CDSC fees of $316, $227, and $24,631 were collected for The London Company Income Equity, Zebra Global Equtiy, and SiM High Yield Opportunities Funds, respectively.

3. Security Valuation and Fair Value Measurements

Investments are valued at the close of the New York Stock Exchange (the “Exchange”), normally 4 p.m. ET, each day that the Exchange is open for business. Equity securities, including exchange-traded funds (“ETFs”), for which market quotations are available are valued at the last sale price or official closing price (closing bid price or last evaluated quote if no sale has occurred) on the primary market or exchange on which they trade.

Debt securities (other than short-term securities) normally are valued on the basis of prices provided by an independent pricing service and may take into account appropriate factors such as institution-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The prices of debt securities may be determined using quotes obtained from brokers.

Investments in open-end mutual funds are valued at the closing net asset value (“NAV”) per share of the mutual fund on the day of valuation. Investment grade short-term obligations with 60 days or less to maturity are valued using the amortized cost method, which approximates market value.

Securities for which the market prices are not readily available or are not reflective of the fair value of the security, as determined by the Manager, will be priced at fair value following procedures approved by the Trust’s Board of Trustees (the “Board”).

Futures contracts are valued based upon their quoted daily settlement prices. Upon entering into a futures contract, a Fund is required to deposit with its futures broker, an amount of cash or U.S. Government and Agency Obligations in accordance with the initial margin requirements of the broker or exchange. Futures contracts are marked to market daily and an appropriate payable or receivable for the change in value (“variation margin”) is recorded by the Fund. Gains or losses are recognized but not considered realized until the contracts expire or are closed. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed on the Statements of Assets and Liabilities.

Other investments, including restricted securities, and those financial instruments for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the Manager in accordance with procedures approved by the Board.

For valuation purposes, the last quoted prices of non-U.S. equity securities may be adjusted under the circumstances described below. If a Manager determines that developments between the close of a foreign market and the close of the Exchange will, in its judgment, materially affect the value of some or all of a fund’s portfolio securities, the Manager will adjust the previous closing prices to reflect what it believes to be the fair value of the securities as of the close of the Exchange. In deciding whether it is necessary to adjust closing prices to reflect fair value, the Manager reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U.S. markets that represent foreign securities and baskets of foreign securities. The Valuation Committee may also

40

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2013

fair value securities in other situations, such as when a particular foreign market is closed but a Fund is open. The Funds use outside pricing services to provide closing prices and information to evaluate and/or adjust those prices. As a means of evaluating its security valuation process, the Valuation Committee routinely compares closing prices, the next day’s opening prices in the same markets, and adjusted prices.

Valuation Inputs

Various inputs may be used to determine the value of the Funds’ investments. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

Level 1	-	Quoted prices in active markets for identical securities.
Level 2	-	Prices determined using other significant observable inputs. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and others.
Level 3	-	Prices determined using other significant unobservable inputs. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in pricing an investment, and would be based on the best information available.

Level 1 and Level 2 trading assets and trading liabilities, at fair value.

Fixed income securities including corporate, convertible and municipal bonds and notes, U.S. government agencies, U.S. treasury obligations, sovereign issues, bank loans, convertible preferred securities and non-U.S. bonds are normally valued by pricing service providers that use broker dealer quotations, reported trades or valuation estimates from their internal pricing models. The service providers’ internal models use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar assets. Securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Fixed income securities purchased on a delayed-delivery basis are marked to market daily until settlement at the forward settlement date and are categorized as Level 2 of the fair value hierarchy.

Mortgage-related and asset-backed securities are usually issued as separate tranches, or classes, of securities within each deal. These securities are also normally valued by pricing service providers that use broker dealer quotations or valuation estimates from their internal pricing models. The pricing models for these securities usually consider tranche-level attributes, current market data, estimated cash flows and market-based yield spreads for each tranche, and incorporates deal collateral performance, as available. Mortgage-related and asset-backed securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Common stocks, ETFs and financial derivative instruments, such as futures contracts or options contracts that are traded on a national securities exchange, are stated at the last reported sale or settlement price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy. Valuation adjustments may be applied to certain securities that are solely traded on a foreign exchange to account for the market movement between the close of the foreign market and the close of the Exchange. These securities are valued using pricing service providers that consider the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments. Securities using these valuation adjustments are categorized as Level 2 of the fair value hierarchy. Preferred securities and other equities traded on inactive markets or valued by reference to similar instruments are also categorized as Level 2 of the fair value hierarchy.

41

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2013

Investments in registered open-end investment management companies will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy. Investments in privately held investment funds which are redeemable within 90 days of the measurement date, will be valued based upon the NAVs of such investments and are categorized as Level 2 of the fair value hierarchy. Short-term investments having a maturity of 60 days or less are generally valued at amortized cost which approximates fair value. These investments are categorized as Level 2 of the fair value hierarchy.

Over-the-counter (“OTC”) financial derivative instruments, such as foreign currency contracts, options contracts, or swaps agreements, derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. These contracts are normally valued on the basis of broker dealer quotations or pricing service providers. Depending on the product and the terms of the transaction, the value of the financial derivative contracts can be estimated by a pricing service provider using a series of techniques, including simulation pricing models. The pricing models use inputs that are observed from actively quoted markets such as issuer details, indices, spreads, interest rates, curves, dividends and exchange rates. Financial derivatives that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

The Funds’ investments are summarized by level based on the inputs used to determine their values. U.S. GAAP also requires all transfers between any levels to be disclosed. The end of the period timing recognition has been adopted for the transfers between levels of each Fund’s assets and liabilities. As of August 31, 2013, there were no transfers between levels. As of August 31, 2013, the investments were classified as described below (in thousands):

Security Transactions and Investment Income

Security transactions are recorded on the trade date of the security purchase or sale. The Funds may purchase securities with delivery or payment to occur at a later date. At the time the Funds enter into a commitment to purchase a security, the transaction is recorded and the value of the security is reflected in the NAV. The value of the security may vary with market fluctuations.

Dividend income, net of foreign taxes, is recorded on the ex-dividend date except certain dividends from foreign securities which are recorded as soon as the information is available to the Funds. Interest income is earned from settlement date, recorded on the accrual basis, and adjusted, if necessary, for accretion of discounts and amortization of premiums. For financial and tax reporting purposes, realized gains and losses are determined on the basis of specific lot identification.

Currency Translation

All assets and liabilities initially expressed in foreign currency values are converted into U.S. dollar values at the mean of the bid and ask prices of such currencies against U.S. dollars as last quoted by a recognized dealer. Income, expenses, and purchases and sales of investments are translated into U.S. dollars at the rate of exchange prevailing on the respective dates of such transactions. The effect of changes in foreign currency exchange rates on investments is separately identified from the fluctuations arising from changes in market values of securities held and is reported with all other foreign currency gains and losses in the Funds’ Statements of Operations.

Dividends to Shareholders

Dividends from net investment income of the Funds normally will be declared and paid at least annually. Distributions, if any, of net realized capital gains are generally paid at least annually and recorded on the ex-dividend date.

Commission Recapture

The Funds, except for the SiM High Yield Opportunities Fund, have established brokerage commission recapture arrangements with certain brokers or dealers. If a Fund’s investment advisor chooses to execute a

43

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2013

transaction through a participating broker, the broker rebates a portion of the commission back to the Fund. Any collateral benefit received through participation in the commission recapture program is directed exclusively to the Funds. This amount is reported with the net realized gain in the Funds’ Statements of Operations, if applicable.

Allocation of Income, Expenses, Gains, and Losses

Income, expenses (other than those attributable to a specific class), gains, and losses are allocated daily to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class.

Redemption Fees

The SiM High Yield Opportunities Fund imposes a 2% redemption fee on shares held for less than 90 days. The fee is deducted from the redemption proceeds and is intended to offset the trading costs, market impact, and other costs associated with short-term trading activity in the Fund. The “first-in, first-out” method is used to determine the holding period. The fee is allocated to all classes of the Fund prorata based on their respective net assets.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimated.

Other

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liability arising out of the performance of their duties to the Trust. In the normal course of business, the Trust enters into contracts that provide indemnification to the other party or parties against potential costs or liabilities. The Trust’s maximum exposure under these arrangements is dependent on claims that may be made in the future and, therefore, cannot be estimated. The Trust has had no prior claims or losses pursuant to any such agreement.

4. Securities and other Investments

Inflation-Indexed Bonds

The SiM High Yield Opportunities Fund may invest in inflation-indexed bonds. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted based on the rate of inflation. The interest rate on these bonds is generally fixed at issuance at a rate lower than typical bonds. Over the life of an inflation-indexed bond, however, interest will be paid based on a principal value, which is adjusted for inflation. Any increase or decrease in the principal amount of an inflation-indexed bond will be included as interest income on the Statements of Operations, even though investors do not receive their principal until maturity.

Payment In-Kind Securities

The SiM High Yield Opportunities Fund may invest in payment in-kind securities. Payment in-kind securities (“PIKs”) give the issuer the option at each interest payment date of making interest payments in either cash or additional debt securities. Those additional debt securities usually have the same terms, including maturity dates and interest rates, and associated risks as the original bonds. The daily market quotations of the original bonds may include the accrued interest (referred to as a dirty price) and require a prorata adjustment from the unrealized appreciation or depreciation on investment to interest receivable in the Statements of Assets and Liabilities.

Restricted Securities

The SiM High Yield Opportunities Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities may be sold privately, but are required to be registered or exempted from such registration before being sold to the public. Private placement securities are generally considered to be restricted except for those securities traded between qualified institutional investors under the provisions of Rule 144A of the Securities Act of 1933. Disposal of restricted securities may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult to achieve. Restricted securities outstanding at the year ended August 31, 2013 are disclosed in the Notes to the Schedules of Investments.

High-Yield Securities

Non-investment-grade securities are rated below the four highest credit grades by at least one of the public rating agencies (or are unrated if not publicly rated). Participation in high-yielding securities transactions generally involves greater returns in the form of higher average yields. However, participation in such transactions involves greater risks, including sensitivity to economic changes, solvency, and relative liquidity in the secondary trading market. Lower ratings may reflect a greater possibility that the financial condition of the issuer, or adverse changes in general economic conditions, or both, may impair the ability of the issuer to make payments of interest and principal. The prices and yields of lower-rated securities generally fluctuate more than higher-quality securities, and such prices may decline significantly in periods of general economic difficulty or rising interest rates.

Real Estate Investment Trusts

The Funds may own shares of real estate investment trusts (“REITs”) which report information on the source of their distributions annually. The Funds re-characterize distributions received from REIT investments based on information provided by the REITs into the following categories: ordinary income, long-term capital gains, and return of capital. If information is not available on a timely basis from the REITs, the re-characterization will be estimated based on available information which may include the previous year allocation. If new or additional information becomes available from the REITs at a later date, a re-characterization will be made the following year. These re-characterizations are not recorded for financial statement purposes, but as an adjustment to the calculation of taxable income.

Other Investment Company Securities and Other Exchange Traded Products

The Funds may invest in shares of other investment companies, including open-end funds, closed-end funds, business development companies, ETFs, exchange-traded notes (“ETNs”), unit investment trusts, and other investment companies of the Trust. The Funds may invest in investment company securities advised by the Manager or a sub-advisor. Investments in the securities of other investment companies may involve duplication of advisory fees and certain other expenses. By investing in another investment company, a Fund becomes a shareholder of that investment company. As a result, Fund shareholders indirectly will bear a Fund’s proportionate share of the fees and expenses paid by shareholders of the other investment company, in addition to the fees and expenses Fund shareholders directly bear in connection with the Fund’s own operations. These other fees and expenses are reflected as Acquired Fund Fees and Expenses and are included in the Fees and Expenses Table for the Fund in its Prospectus, if applicable. Investments in other investment companies may involve the payment of substantial premiums above the value of such issuer’s portfolio securities.

Master Agreements

The SiM High Yield Opportunities Fund is a party to International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreements”) with counterparties that govern transactions in over-the-counter derivative and foreign exchange contracts entered into by the Fund and those counterparties. The ISDA Master Agreements contain provisions for general obligations, representations, agreements, collateral and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement. Any election to terminate early could be material to the financial statements. Since different types of forward and OTC financial derivative transactions have different mechanics and are sometimes traded out of different legal entities of a particular counterparty organization, each type of transaction may be covered by a different Master Agreement, resulting in the need for multiple agreements with a single counterparty. As the Master Agreements are specific to unique operations of different asset types, they allow a Fund to net its total exposure to a counterparty in the event of a default with respect to all the transactions governed under a single agreement with a counterparty.

Master Repurchase Agreements (“Master Repo Agreements”) govern transactions between a Fund and select counterparties. The Master Repo Agreements maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for Repurchase and Reverse Repurchase Agreements.

Master Securities Forward Transaction Agreements (“Master Forward Agreements”) govern the considerations and factors surrounding the settlement of certain forward settling transactions, such as delayed delivery or sale-buyback financing transactions by and between a Fund and select counterparties. The Master Forward Agreements maintain provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral.

5. Financial Derivative Instruments

The Funds may utilize derivative instruments to enhance return, hedge risk, gain efficient exposure to an asset class or to manage liquidity. When considering the Fund’s use of derivatives, it is important to note that the Fund does not use derivatives for the purpose of creating financial leverage.

Swap Agreements

The SiM High Yield Opportunities Fund may invest in swap agreements. Swap agreements are privately negotiated agreements between the Fund and a counterparty to exchange or swap investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals. The Fund may enter into credit default, cross-currency, interest rate and other forms of swap agreements to manage its exposure to credit, currency, interest rate, and inflation risk. In connection with these agreements, securities or cash may be identified as collateral in accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default or bankruptcy/insolvency.

Swaps are marked to market daily based upon values from third party vendors or quotations from market makers to the extent available and the change in value, if any, is recorded as an unrealized gain or loss on the Statements of Assets and Liabilities. In the event that market quotes are not readily available and the swap cannot be valued pursuant to one of the valuation methods, the value of the swap will be determined in good faith by the Valuation Committee pursuant to procedures approved by the Board.

Payments received or made at the beginning of the measurement period are reflected as such on the Statements of Assets and Liabilities and represent payments made or received upon entering into the swap agreement to compensate for differences between the stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, interest rates, and other relevant factors). These

46

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2013

upfront payments are recorded as realized gains or losses on the Statements of Operations upon termination or maturity of the swap. A liquidation payment received or made at the termination of the swap is recorded as realized gain or loss on the Statements of Operations. Net periodic payments received or paid by a Fund are included as part of realized gains or losses on the Statements of Operations.

Entering into these agreements involves, to varying degrees, elements of credit, market and documentation risk in excess of the amounts recognized on the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements and that there may be unfavorable changes in interest rates.

A Fund’s maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from the counterparty over the contract’s remaining life, to the extent that amount is positive. The risk is mitigated by having a master netting arrangement between a Fund and the counterparty and by the posting of collateral to a Fund to cover a Fund’s exposure to the counterparty.

Credit Default Swap Agreements

Credit default swap agreements involve one party making a stream of payments (referred to as the buyer of protection) to another party (the seller of protection) in exchange for the right to receive a specified return in the event of a default or other credit event for the referenced entity, obligation or index. As a seller of protection on credit default swap agreements, the Fund will generally receive from the buyer of protection a fixed rate of periodic premium throughout the term of the swap provided that there is no credit event. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure up to the notional amount of the swap.

If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. If the Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. Recovery values are estimated by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value.

Credit default swap agreements on corporate issues, sovereign issues of an emerging country or U.S. municipal issues involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a default or other credit event. If a credit event occurs and cash settlement is not elected, a variety of other deliverable obligations may be delivered in lieu of the specific referenced obligation. The ability to deliver other obligations may result in a cheapest-to-deliver option (the buyer of protection’s right to choose the deliverable obligation with the lowest value following a credit event). The Fund may use credit default swaps on corporate issues, sovereign issues of an emerging country or U.S. municipal issues to provide a measure of protection against defaults of the issuers (i.e., to reduce risk where the Fund owns or has exposure to the referenced obligation) or to take an active long or short position with respect to the likelihood of a particular issuer’s default.

Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues, sovereign issues of an emerging country or U.S. municipal issues as of period end are disclosed in the Notes to the Schedule of Investments and serve as an indicator of the current status of the payment/performance risk and represent a market participant view of the likelihood or risk of default for the underlying referent security to credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. For credit default swap agreements on asset-backed securities and credit indices, the quoted market prices and resulting values serve as the indicator of the current status of the payment/performance risk. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

The maximum potential amount of future payments (undiscounted) that the Fund as a seller of protection could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement. Notional amounts of each individual credit default swap agreements outstanding as of August 31, 2013 for which the Fund is the seller of protection is disclosed in the Notes to the Schedules of Investments. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into by the Fund for the same referenced entity or entities.

For the six months ended August 31, 2013, the SiM High Yield Opportunities Fund entered into credit default swaps primarily for return enhancement, hedging, and exposing cash to markets.

The Fund’s credit default swap contract notional amounts outstanding fluctuate throughout the operating year as required to meet the strategic requirements. The following table illustrates the quarterly volume of credit default swap contracts. For the purpose of this disclosure, the volume is measured by the notional amounts outstanding at each quarter end (000’s).

	Credit Default Swap Notional Amounts Outstanding

Over-the-Counter Swap Agreements

OTC financial derivative instruments such as forward currency contracts, options contracts, interest rate, and credit default swap agreements derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. These instruments are valued using evaluated prices furnished by a pricing service selected by the Board. In certain cases, when a valuation is not readily available from a pricing service, the Fund’s Manager may provide a valuation pursuant to procedures approved by the Board. Depending on the instrument and the terms of the transaction, the value of the derivative instrument can be determined by a pricing service or the Manager using a series of techniques, including simulation pricing models. The pricing models are inputs, such as issuer details, indices, spreads, interest rates, yield curves, dividends, and exchange rates, that are observed from actively quoted markets. Derivative instruments that use valuation techniques and inputs similar to those described above are normally categorized as Level 2 in the fair valuation hierarchy.

Futures Contracts

Futures contracts are contracts to buy or sell a standard quantity of securities at a specified price on a future date. The Funds may enter into financial futures contracts as a method for keeping assets readily convertible to cash if needed to meet shareholder redemptions or for other needs while maintaining exposure to the stock or bond market, as applicable. The primary risks associated with the use of futures contracts are the possibility of illiquid markets or imperfect correlation between the values of the contracts and the underlying securities, or that the counterparty will fail to perform its obligations.

Upon entering into a futures contract, the Fund is required to set aside or deposit with a broker an amount, termed the initial margin, which typically represents a portion of the face value of the futures contract. The Funds usually reflects this amount on the Schedule of Investments as a U.S. Treasury Bill held as collateral for futures contracts or as Cash deposited with broker on the Statements of Assets and Liabilities. Payments to and from the broker, known as variation margin, are required to be made on a daily basis as the price of the futures contract fluctuates. Changes in initial settlement values are accounted for as unrealized appreciation (depreciation) until the contracts are terminated, at which time realized gains and losses are recognized. Futures contracts are valued at the most recent settlement price established each day by the exchange on which they are traded.

For the six months ended August 31, 2013, the Funds entered into future contracts primarily for return enhancement, hedging and exposing cash to markets.

The Funds’ futures contracts outstanding fluctuate throughout the operating year as required to meet strategic requirements. The following table illustrates the quarterly volume of futures contracts. For purpose of this disclosure, volume is measured by contracts outstanding at period end.

6. Principal Risks

In the normal course of business the Funds trade financial instruments and enter into financial transactions where risk of potential loss exists. Security values fluctuate (market risk) and may decline due to factors affecting securities markets in general, particular industries represented in the securities markets or conditions specifically related to a particular company. Failure of the other party to a transaction to perform (credit risk), for example by not making principal and interest payments when due, reduces the value of the issuer’s debt and could reduce the Funds’ income. Similar to credit risk, the Funds may be exposed to counterparty risk, or the risk that an institution or other entity with which the Funds have unsettled or open transactions will fail to make required payments or otherwise comply with the terms of the instrument, transaction or contract. The potential loss could exceed the value of the financial assets recorded in the financial statements. Some of the Funds’ investments may be illiquid and the Funds may not be able to vary the portfolio investments in response to changes in economic and other conditions. If a Fund is required to liquidate all or a portion of its investments quickly, the Fund may realize significantly less than the value at which it previously recorded those investments.

In the normal course of business the Funds trade financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk), or failure or inability of the other party to a transaction to perform (credit and counterparty risk). See below for a detailed description of select principal risks.

Market Risks

The Funds’ investments in financial derivatives and other financial instruments expose the Funds to various risks such as, but not limited to, interest rate, foreign currency and equity risks.

Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates. As nominal interest rates rise, the value of certain fixed income securities held by the Fund is likely to decrease. A nominal interest rate can be described as the sum of a real interest rate and an expected inflation rate. Fixed income securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile than securities with shorter durations. Duration is useful primarily as a measure of the sensitivity of a fixed income’s market price to interest rate (i.e. yield) movements.

If the Funds invest directly in foreign currencies or in securities that trade in, and receive revenues in, foreign currencies, or in financial derivatives that provide exposure to foreign currencies, they will be subject to the risk that those currencies will decline in value relative to the base currency of the Funds, or, in the case of hedging positions, that the Funds’ base currency will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. As a result, the Funds’ investments in foreign currency denominated securities may reduce the returns of the Fund.

The fair values of equities, such as common stocks and preferred securities or equity related investments such as futures and options, 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 investor sentiment generally. They may also decline due to factors which affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities and equity related investments generally have greater market price volatility than fixed income securities.

Credit and Counterparty Risks

The SiM High Yield Opportunities Fund will be exposed to credit risk with respect to issuers of portfolio securities. The Fund minimizes concentrations of credit risk by undertaking transactions with a large number of issuers. The Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a financial derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings.

Similar to credit risk, the SiM High Yield Opportunities Fund may be exposed to counterparty risk, or the risk that an institution or other entity with which the Fund has unsettled or open transactions will default. Financial assets, which potentially expose the Fund to counterparty risk, consist principally of cash due from counterparties and investments. Furthermore, to the extent that unpaid amounts owed to the Fund exceed a predetermined threshold agreed to with the counterparty, such counterparty shall advance collateral to the Fund in the form of cash or cash equivalents equal in value to the unpaid amount owed to the Fund. The Fund may invest such collateral in securities or other instruments and will typically pay interest to the counterparty on the collateral received. If the unpaid amount owed to the Fund subsequently falls, the Fund would be required to return to the counterparty all or a portion of the collateral previously advanced to the Fund.

All transactions in listed securities are settled/paid for upon delivery using approved counterparties. The risk of default is considered minimal, as delivery of securities sold is only made once the Fund has received payment. Payment is made on a purchase once the securities have been delivered by the counterparty. The trade will fail if either party fails to meet its obligation.

Notes to Financial Statements

The SiM High Yield Opportunities Fund is subject to various Master Agreements, which govern the terms of certain transactions with select counterparties. These Master Agreements reduce the counterparty risk associated with relevant transactions by specifying credit protection mechanisms and providing standardization that improves legal certainty. Since different types of forward and OTC derivative transactions have different mechanics and are sometimes traded out of different legal entities of a particular counterparty organization, each type of transaction may be covered by a different Master Agreement and result in the need for multiple agreements with a single counterparty. Therefore, exposure cannot be netted and collateralized across all types of transactions. Exposures can only be netted across transactions governed under the same Master Agreement with the same legal entity.

Master Agreements can also help limit counterparty risk by specifying collateral posting arrangements at pre-arranged exposure levels. Under the Master Agreements, collateral is routinely transferred if the total net exposure to certain transactions (net of existing collateral already in place) governed under the relevant Master Agreement with a counterparty in a given account exceeds a specified threshold, which typically ranges from zero to $250,000 depending on the counterparty and the type of Master Agreement. United States Treasury bills and US dollar cash are generally the preferred forms of collateral, although other forms of AAA rated paper may be used. The Fund’s overall exposure to counterparty risk can change substantially within a short period, as it is affected by each transaction subject to the relevant Master Agreement. Master Repurchase Agreements (“Master Repo Agreements”) govern transactions between the Fund and select counterparties. The Master Repo Agreements maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for Repurchase Agreements.

Master Securities Forward Transaction Agreements (“Master Forward Agreements”) govern the considerations and factors surrounding the settlement of certain purchases and sales made on a delayed-delivery basis by and between the Fund and select counterparties. The Master Forward Agreements maintain provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral.

International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreements”) govern OTC financial derivative transactions entered into by the SiM High Yield Opportunities Fund and those counterparties. The ISDA Master Agreements maintain provisions for general obligations, representations, agreements, collateral and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement. Any election to early terminate could be material to the financial statements. The fair value of OTC financial derivative transactions net of collateral received in or pledged by counterparty as of period end is disclosed in the Notes to the Schedule of Investments.

7. Federal Income and Excise Taxes

It is the policy of each Fund to qualify as a regulated investment company (“RIC”), by complying with all applicable provisions of Subchapter M of the Internal Revenue Code, as amended, and to make distribution of taxable income sufficient to relieve it from substantially all federal income and excise taxes. For federal income tax purposes, each Fund is treated as a single entity for the purpose of determining such qualification.

The Funds do not have any unrecognized tax benefits in the accompanying financial statements. The tax years for the periods ended August 31, 2011, 2012 and 2013 remain subject to examination by the Internal Revenue Service. If applicable, the Funds recognized interest accrued related to unrecognized tax benefits in interest expense and penalties in “Other expenses” on the Statements of Operations.

Dividends are categorized in accordance with income tax regulations which may treat certain transactions differently than U.S. generally accepted accounting principles. Accordingly, the character of distributions and composition of net assets for tax purposes may differ from those reflected in the accompanying financial statements.

A Fund may be subject to taxes imposed by countries in which it invests. Such taxes are generally based on returns of income earned or gains realized or repatriated. Taxes are accrued and applied to net investment income, net realized capital gains and net unrealized appreciation or depreciation, as applicable, as the income is earned or capital gains are recorded.

Financial reporting records are adjusted for permanent book/tax differences to reflect tax character. Financial records are not adjusted for temporary differences. The temporary differences between financial reporting and tax-basis reporting of unrealized appreciation or (depreciation) are attributable primarily to the tax deferral of losses from wash sales, the realization for tax purposes of unrealized gains or(losses) on certain derivative instruments and the reclassification of income from real estate investment securities, royalty trusts, and publicly traded partnerships.

Due to inherent differences in the recognition of income, expenses and realized gains or (losses) under U.S. GAAP and federal income tax regulations, permanent differences between book and tax reporting have been identified and appropriately reclassified on the Statements of Assets and Liabilities.

Accordingly, the following amounts represent current year permanent differences derived from foreign currency, paydown reclasses, reclassifications of income from real estate investment securities, publicly traded partnerships, and royalty trusts, and dividend reclasses that have been reclassified as of August 31, 2013 (in thousands):

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “RIC MOD”) was enacted, which changed various technical rules governing the tax treatment of regulated investment companies. The changes are generally effective for taxable years beginning after the date of enactment. One of the more prominent changes addresses capital loss carryforwards. Under the RIC MOD, each Fund will be permitted to carry forward capital losses incurred in taxable years beginning after the date of enactment for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years, which carry an expiration date. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital loss carryforwards will retain their character as either short-term or long-term capital losses rather than being considered all short-term as permitted under previous regulation.

Finally, the RIC MOD contains several provisions aimed at preserving the character of distributions made by a fiscal year RIC during the portion of its taxable year ending after October 31 or December 31, reducing the circumstances under which a RIC might be required to file amended Forms 1099 to restate previously reported distributions. Except for the simplification provisions related to RIC qualification, the RIC MOD is effective for taxable years beginning after December 22, 2010. The provisions related to RIC qualification are effective for taxable years for which the extended due date of the tax return is after December 22, 2010.

As of August 31, 2013, the Funds did not have capital loss carryforwards.

Disclosure Regarding the Board of Trustees’ Approval of the Management

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

At its May 29, 2013 meeting, the Board of Trustees (“Board”) considered the renewal of the Management Agreement between American Beacon Advisors, Inc. (“Manager”) and the American Beacon Funds (“Beacon Trust”) on behalf of each of their series (collectively, the “Funds”) and the renewal of each investment advisory agreement between the Manager and a subadvisor (each an “Investment Advisory Agreement”). The Management Agreement and the Investment Advisory Agreements are collectively referred to herein as the “Agreements.” In preparation for the Board’s consideration to renew and approve these Agreements, the Board and its Investment Committee undertook steps to gather and consider information furnished by the Manager, the subadvisors, Lipper, Inc. (“Lipper”) and Morningstar, Inc. (“Morningstar”). The Board, with the assistance of independent legal counsel, requested and received certain relevant information from the Manager and each subadvisor.

In addition, the Board’s Investment Committee worked with Lipper to obtain relevant comparative information regarding the performance, fees and expenses of the Funds. The Investment Committee, for the benefit of all Trustees, sponsored a separate meeting on May 10, 2013 to consider the information provided by Lipper. Further, the Board took into consideration information furnished for the Board’s review and consideration throughout the year at regular Board and Investment Committee meetings, as well as information specifically prepared in connection with the renewal process.

In connection with the Board’s consideration of the Management Agreement and each Investment Advisory Agreement, the Trustees received and evaluated such information as they deemed necessary. The information requested by the Board included, among other information, the following materials. For various reasons, a subadvisor may not have provided responses to each requested item. In these instances, the Board considered the materials that were received from such subadvisor. References herein to the “firm” refer to the Manager and/or each applicable subadvisor.

In connection with the Management Agreement and each Investment Advisory Agreement, the Board also obtained an analysis provided by Lipper that compared: (i) investment performance of each Fund versus comparable investment companies and appropriate indices; (ii) total Fund expenses of each Fund versus comparable mutual funds; and (iii) each Fund’s investment advisory fee rate versus comparable mutual funds. For certain Funds, the Board also considered information regarding the performance of the Manager and individual subadvisors with respect to their allocated portions of a Fund’s portfolio, net of management or subadvisory fees, as applicable, but not other Fund expenses. For each Fund with more than one class of shares, the class of shares used for comparative purposes was the class with the longest performance history, which in most cases was the Institutional Class. The Board also considered that the use of Institutional Class performance generally facilitates a meaningful comparison for expense and performance purposes.

Disclosure Regarding the Board of Trustees’ Approval of the Management Agreement and Investment

Advisory Agreements of the Funds (Unaudited)

Provided below is an overview of the primary factors the Trustees considered at the Investment Committee meeting on May 10, 2013 at which the Trustees reviewed the investment performance of the Manager and each subadvisor and the primary factors considered by the Board at its May 29, 2013 meeting at which the Board considered the renewal of the Management Agreement and Investment Advisory Agreements.

The Board did not identify any particular information that was most relevant to its consideration to renew or approve each Agreement, and each Trustee may have afforded different weight to the various factors. Legal counsel to the independent Trustees provided the Board with a memorandum regarding its responsibilities pertaining to the renewal and approval of each Agreement. The memorandum explained the regulatory requirements surrounding the Trustees’ process for evaluating investment advisors and the terms of the contracts. Based on its evaluation, the Board unanimously concluded that the terms of each Agreement were reasonable and fair and that the renewal and approval of each Agreement was in the best interests of the Funds and their shareholders.

Considerations With Respect to the Renewal of the Management Agreement and Each Investment Advisory Agreement

In determining whether to renew the Management Agreement and each Investment Advisory Agreement on behalf of the Funds, the Trustees considered the best interests of each Fund separately. While the Management Agreement and the Investment Advisory Agreements for all of the Funds were considered at the May 29, 2013 meeting, the Board considered each Fund’s investment management and subadvisory relationships separately.

In each instance, the Board considered, among other things, the following factors: (1) the nature, extent and quality of the services provided; (2) the investment performance of a Fund and, as applicable, each subadvisor for a Fund; (3) the costs incurred by the Manager in rendering services to the Funds and its resulting profits or losses; (4) the extent to which economies of scale have been taken into account in setting each fee rate schedule; (5) whether fee rate levels reflect these economies of scale for the benefit of Fund investors; (6) comparisons of services and fee rates with contracts entered into by the Manager or a subadvisor or their affiliates with other clients (such as pension funds and other institutional funds); and (7) any other benefits derived or anticipated to be derived by the Manager or a subadvisor from their relationship with a Fund. The Trustees posed questions to various management personnel of the Manager regarding certain key aspects of the materials submitted in support of the renewal.

Nature, Extent and Quality of Services. With respect to the renewal of the Management Agreement, the Board considered, among other factors: each Fund’s long-term performance and the background and experience of key investment personnel at the Manager; the cost structure of the Funds; the Manager’s culture of compliance and support for compliance operations that reduce risks to the Funds; the Manager’s commitment to enhance the Funds’ product line and increase assets in the Funds; the Manager’s quality of services; the Manager’s active role in monitoring and, as appropriate, recommending additional or replacement subadvisors; the Manager’s commitment to training employees; and the Manager’s efforts to retain key employees and maintain staff levels.

With respect to the renewal of each Investment Advisory Agreement, the Trustees considered the level of staffing, quality, background and experience of each subadvisor’s investment personnel responsible for managing the Funds, the size of the subadvisor and the subadvisor’s ability to continue to attract and retain qualified investment personnel. The Board also considered the adequacy of the resources committed to the Funds by each subadvisor, and whether those resources were commensurate with the needs of the Funds and are sufficient to sustain appropriate levels of performance and compliance needs. In this regard, the Board considered the financial stability of each subadvisor. The Board also considered the subadvisors’ representations regarding their compliance programs and codes of ethics. Based on the foregoing information, the Board concluded that the nature, extent and quality of the management and advisory services provided by the Manager and each subadvisor were appropriate for each Fund and, thus, determined to renew the Management Agreement and the Investment Advisory Agreement for each Fund.

Investment Performance. The Board evaluated the comparative information provided by Lipper and the Manager regarding each Fund’s investment performance relative to its Lipper performance universe, Lipper performance group, and/or benchmark index(es). The Board considered the information provided by Lipper regarding its independent peer selection methodology to select all performance groups and universes. The Board also considered that the performance groups and universes selected by Lipper may not provide appropriate comparisons for each Fund. In addition, the Board considered the performance reports and discussions with management at Board and Committee meetings throughout the year. The Board also considered in each instance the Manager’s recommendation to continue to retain each subadvisor. A discussion regarding the Board’s considerations with respect to each Fund’s performance appears below under “Additional Considerations and Conclusions with Respect to Each Fund.”

Costs of the Services Provided to the Funds and the Profits Realized by the Manager from its Relationship with the Funds. In analyzing the cost of services and profitability of the Manager, the Board considered the revenues earned and the expenses incurred by the Manager. The profits or losses were noted at both an aggregate level for all Funds and at an individual Fund level, with some Funds being profitable for the Manager and with the Manager sustaining losses with respect to other Funds. Although the Board noted that, in certain cases, the fee rates paid by other clients of the Manager are lower than the fee rates paid by the Funds, the difference reflects the greater level of responsibility and regulatory requirements associated with managing the Funds.

The Board also noted that the Manager proposed to continue the expense waivers and reimbursements for certain Funds and classes that were in place during the last fiscal year. The Board further considered that with respect to each Fund, the Management Agreement provides for the Manager to receive a management fee comprised of an annualized fee that is retained by the Manager plus the amount payable by the Manager to a subadvisor. The Board also considered that the Manager receives service and administrative fees to compensate the Manager for providing administrative services to the Funds and to compensate third-party administrators and broker-dealers for services to Fund shareholders. In addition, the Board considered that the Manager receives management fees for overseeing the securities lending program on behalf of various Funds. The Board also noted that certain classes of the Funds maintain higher expense ratios in order to compensate third-party distributors.

Disclosure Regarding the Board of Trustees’ Approval of the Management

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

In analyzing the cost of services for each subadvisor in connection with its investment advisory services to the Fund, the Board considered that, in many cases, the Manager has negotiated the lowest subadvisory fee rate a subadvisor charges for any comparable client accounts. The Board did not request profitability data from the subadvisors because the Board did not view this data as imperative to its deliberations given the arm’s-length nature of the relationship between the Manager and the subadvisors with respect to the negotiation of subadvisory fee rates. In addition, the Board noted that subadvisors may not account for their profits on an account-by-account basis and, those that do, likely employ different methodologies in connection with these calculations.

Based on the foregoing information, the Board concluded that the profitability levels of the Manager were reasonable in light of the services performed by the Manager. A discussion regarding the Board’s considerations with respect to each Fund’s fee rates is set forth below under “Additional Considerations and Conclusions with Respect to Each Fund.”

Economies of Scale. In considering the reasonableness of the management and investment advisory fees rates, the Board considered whether economies of scale will be realized as the Funds grow and whether fee rate levels reflect these economies of scale for the benefit of Fund shareholders. In this regard, the Board considered that the Manager has negotiated breakpoints in many subadvisory fee rates. The Board also noted that, for purposes of determining the fee rates chargeable to the Funds, many subadvisors have agreed to take into account assets of AMR Corporation and its pension plans that are managed by the subadvisors. Thus, the Funds are able to receive lower effective fee rates.

In addition, the Board noted the Manager’s representation that many of the Funds benefit from economies of scale because comparably low fee rate levels are reflected in the current management and administration fee rates the Manager charges. The Board further noted the Manager’s representation that many of the Funds benefit from these comparably low fee rate levels despite not having yet reached an asset size at which economies of scale would traditionally be considered to exist, and the Manager’s belief that breakpoints are not appropriate at this time. Based on the foregoing information, the Board concluded that the Manager and subadvisor fee rate schedules for each Fund provide for a reasonable sharing of benefits from any economies of scale with the Funds.

Benefits Derived from the Relationship with the Funds. The Board considered the “fall-out” or ancillary benefits that accrue to the Manager and/or the subadvisors as a result of the advisory relationships with the Funds, including greater exposure in the marketplace with respect to the Manager’s or subadvisor’s investment process and expanding the level of assets under management by the Manager and the subadvisors.

In addition, the Manager noted that the Funds also derive benefits from their association with the Manager. Specifically, the Board noted the Manager’s representation that it provides services to most Funds at a lower than industry average cost. The Board considered that certain of the subadvisors reimburse the Manager for certain of its costs relating to distribution activities for the Funds. The Board also considered that the Funds did not pay commissions to any affiliated broker-dealer of the Manager or the relevant subadvisor during the most recent fiscal year ended December 31, 2012.

Based on the foregoing information, the Board concluded that the potential benefits accruing to the Manager and the subadvisors by virtue of their relationships with the Funds appear to be fair and reasonable.

Additional Considerations and Conclusions with Respect to Each Fund

The performance comparisons below were made versus each Fund’s Lipper performance universe median, Lipper performance group median and/or benchmark index. References below to each Fund’s Lipper performance group and Lipper performance universe are to the respective group or universe of comparable mutual funds included in the analysis provided by Lipper. A Lipper performance group consists of the Fund and a representative sample of funds with similar investment classifications and objectives as the Fund, as selected by Lipper. A Lipper performance universe is an expansion of the performance group, providing a broader view of performance across the Fund’s investment classification/objective and allowing for a more extensive comparison. In reviewing the performance, the Trustees viewed longer-term performance over a full market cycle, typically five years or longer, as the most important consideration, because relative performance over shorter periods may be significantly impacted by market or economic events that do not reflect manager skill.

The expense comparisons below were made versus each Fund’s Lipper expense universe median and Lipper expense group median. References below to each Fund’s expense group and expense universe are to the respective group or universe of comparable mutual funds included in the analysis by Lipper. A Lipper expense group consists of the Fund and a representative sample of funds with similar operating structures, as selected by Lipper. A Lipper expense universe includes all funds in the investment classification/objective with a similar load type to the share class of the Fund included in the Lipper comparative information and provides a broader view of expenses across the Fund’s investment classification/objective. The Trustees also considered a Fund’s Morningstar fee level category. In reviewing expenses, the Trustees considered the positive impact of fee waivers where applicable and the Manager’s agreement to continue the fee waivers. In addition, information regarding the use of soft dollars was requested from the Manager and all subadvisors and was considered by the Trustees.

Based on these and other considerations, the Trustees: (1) concluded that the fees paid to the Manager and subadvisor under the Management and Investment Advisory Agreements are fair and reasonable; (2) determined that the American Beacon SiM High Yield Opportunities Fund and its shareholders would benefit from the Manager’s and subadvisor’s continued management of the Fund; and (3) approved the renewal of the Management and Investment Advisory Agreements with respect to the American Beacon SiM High Yield Opportunities Fund.
