Important Information: There is no guarantee that each Fund’s investment objective will be met. Because the Flexible Bond 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 most 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 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.

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.

Dear Shareholders,

Fixed-income instruments have been a remarkably strong option for investors in recent years. Although equities have come back solidly from their downturn during 2008 and 2009, with the S&P 500 Index returning an annual average of 6.5% over the past ten years, returns from both the leading corporate bond index (the BofA Merrill Lynch U.S. Corporate Index) and the leading U.S. Treasury index (the BofA Merrill Lynch U.S. Treasury Index) have outperformed that rate for the same period.

This is an excellent landscape for skilled bond fund managers who are given a wide amount of latitude to seek out many varieties of fixed-income vehicles. We are fortunate to have three of them sub-advising the American Beacon Flexible Bond Fund.

As a result of their expertise, the American Beacon Flexible Bond Fund (Institutional Class) returned 6.34% for the 12-month period ended August 31, 2012.

Since its inception just over a year ago, this Fund has been a worthy addition to American Beacon’s suite of investment choices. With the global economy still sluggish in its recovery, we expect fixed-income investments to remain a vital choice for investors for some time to come, and we’re pleased to be able to offer a Fund designed with the flexibility to benefit from the opportunities the sub-advisors find in the market.

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.

Global Bond Market Overview

August 31, 2012 (Unaudited)

Since the U.S. financial crisis of 2008, the global capital markets have been roiled by a contest between two conflicting sets of macroeconomic forces. On one side are the forces of debt deleveraging, which reduce growth and are deflationary. On the other side are the efforts of central banks to reinflate through balance sheet expansion.

Complicating things even more is that different central banks have reacted differently. The U.S. Federal Reserve has been the most aggressive, while the People’s Bank of China has been tapping on the brakes from mid-2009 until the end of last year. This roller coaster investment environment of “risk-on” or “risk-off” has dominated other factors for most of the past few years, making it very hard for investors to diversify outside of this general pattern.

At first glance, this year played pretty much to the same script. It started with a bang when the European Central Bank (ECB) launched a massive but unorthodox monetization operation through the Longer-Term Refinancing Operations to prevent a Lehman-like seizure in the financial system. While the infusion of liquidity temporarily stabilized markets, it did not address the ongoing balance sheet issues facing both sovereigns and the private sector.

Risk assets came under renewed pressure in the second quarter of 2012 as European political uncertainty intensified, sovereigns and financials were downgraded, and weaker U.S. economic data challenged the modest U.S. cyclical recovery. A desire to avoid risk drove down interest rates across developed markets, including the U.S. and Germany, where yields touched historic lows. By contrast, sovereign yields in Spain and Italy rose towards prohibitive levels, while Greece’s elections failed to help its deteriorating economy.

There has been a subtle change in risk-asset correlations since the start of the year. The U.S. stock market is up while the euro is down, a departure from the correlation of the last three years. Investors have become more discriminating in their determination of risk and are less willing to throw out the good with the bad so long as the world economy is not sinking into recession or a global financial meltdown.

Even though U.S. economic growth has been disappointing this year, underlying private-sector real gross domestic product (GDP) growth has averaged 3.1% since the second quarter of 2009. This is a respectable rate considering the dire state of housing, the associated lack of new credit demand, and the more recent fiscal drag over the past year. Since 2011, public-sector retrenchment at the state level and the prospect of a sequester happening at the end of this year have shaved an annualized 1% off of GDP growth. Add to this the uncertainty related to Europe along with next year’s U.S. “fiscal cliff,” and it is easy to see why businesses and households may adopt a wait-and-see stance. Nonetheless, the recessionary consequences of not changing the current budget laws are so strong that any adjustment in this direction will be a positive.

China’s economic growth rate appears close to a trough. The Chinese authorities have been reversing the policy dials since the start of the year. The authorities want a soft landing to a sustainable growth level as part of a longer-term strategy aimed at moving away from China’s boom-bust pattern, with a greater reliance on domestic consumption and less of a focus on expanding foreign exports.

Europe’s economic crisis is really a political crisis. It could be easily resolved by allowing the ECB to monetize some of the existing claims in the system. It could engage in U.S.- or U.K.-style quantitative easing operations and buy sovereign bonds. In the end, self-preservation may prevail over political dysfunction. The EU summit at the end of June laid out the groundwork of a workable recapitalization plan for Europe’s banks. It won’t be as speedy as the U.S. process, but it could be an important turning point in Europe’s seemingly endless crisis. The EU also has been making progress on the recapitalization of Spain’s banking sector, which could reduce significantly the threat of a deep credit contraction.

Global growth is not strong but it is positive, while regional growth is very desynchronized. U.S. economic growth has fallen short of the expectations of many observers, but the private sector is still doing better than generally acknowledged. China is in transition as its leaders seek to stabilize growth. These two economic regions are critical because they are the important drivers of the world economy. As for

Europe, based on the landmark decision to create a single bank supervisor along with the decision to allow direct recapitalization from the European Stability Mechanism, it looks like the political will exists to prevent a break-up of the union.

The big question is still the outlook for the global economy. The risk of a catastrophic financial failure has eased somewhat since last year but markets are still priced for a pessimistic growth outlook.

Performance Overview

August 31, 2012 (Unaudited)

The Investor Class of the Flexible Bond Fund (the “Fund”) returned 5.99% for the twelve months ended August 31, 2012. The Fund outperformed the BofA Merrill Lynch 3-Month LIBOR Index (the “Index”) return of 0.45%. 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.

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.

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.

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 1.36%, 1.46%, 1.74%, 1.86% and 2.60%, 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 high quality nature of the Fund’s fixed income holdings proved beneficial in achieving its return objective. Securities issued by the United States Treasury and foreign Sovereign governments represented a significant portion of the Fund’s assets during the period. Aggregating the two security types, the average allocation for the period was approximately 55% of fixed income holdings. Treasuries maintained a larger allocation in the Fund, however they lagged the returns generated by Sovereign issues (+2.2% vs. +7.6% respectively).

Corporate fixed income holdings also had a sizeable allocation within the Fund and provided a positive contribution to the return generated over the period. Among the Corporate holdings, positions in the Financial sector had the most significant impact. Financials represented 10.9% of the Fund’s 16.9% overall allocation to Corporate securities. As a group, the Fund’s Financial sector fixed income positions gained 6.2%.

The Fund’s longer-dated fixed income securities generally outperformed its shorter-dated securities. Securities with a duration greater than 5 years generated strong absolute returns (in some cases double-digit gains) and benefited from a declining rate environment further out on the yield curve. While the Fund experienced the greatest benefit during the period from longer duration securities, the majority of the fixed income securities have a duration between zero to three years (70.7% of the assets on average over the

American Beacon Flexible Bond Fund ^SM

Performance Overview

August 31, 2012 (Unaudited)

period). The shorter duration securities also had a positive contribution to the Fund’s return, just not to the extent of the longer-dated securities.

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 purposes of creating financial leverage. During the period, the Fund experienced modest benefits from the use of derivatives in foreign currency transactions in addition to investments made in futures, options, and 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, 2012 (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, 2012 through August 31, 2012.

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 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 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 3/1/12		Ending Account Value 8/31/12		Expenses Paid During Period* 3/1/12 - 8/31/12

Actual	$	1,000.00	$	1,034.50	$	4.65

Hypothetical **	$	1,000.00	$	1,020.16	$	5.03
Investor Class
Actual	$	1,000.00	$	1,031.78	$	6.49

Hypothetical **	$	1,000.00	$	1,018.25	$	6.95

Expenses are equal to the Fund’s annualized expense ratios for the six-month period of 0.91%, 0.99%, 1.27%, 1.42% and 1.37% 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 (366) to reflect the half year period.

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 comprising the American Beacon Funds) (the “Fund”) as of August 31, 2012, the related statement of operations for the year then ended, and the statement of changes in net assets 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 Fund’s 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, 2012, 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, 2012, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

⁽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⁾

^-(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.

Notes to Financial Statements

August 31, 2012

1. Organization and Significant Accounting Policies

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 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		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 May 2011, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) ASU No. 2011-04 “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) and the International Financial Reporting Standards (“IFRSs”)”. ASU No. 2011-04 amends FASB ASC Topic 820, Fair Value Measurements and Disclosures, to establish common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. GAAP and IFRSs. ASU No. 2011-04 is effective for fiscal years beginning after December 15, 2011 and for interim period March 1, 2012 to August 31, 2012.

Management has evaluated the implications of these changes and determined that the impact of the new guidance will only affect the disclosure requirements related to the financial statements. However, as the Fund did not hold any Level 3 investments as of August 31, 2012, the financial statement disclosures were not affected.

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 Management Agreement, the Manager receives from the Fund 0.05% of the average daily net assets plus

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2012

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, 2012 were as follows (dollars in thousands):


Management Fee Rate	Management Fee		Amounts paid to Investment Advisors		Net Amounts Retained by Manager
0.60%	$	316	$	290	$	26

Of this amount, $63,410 was payable to the Manager at August 31, 2012.

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, 2012, the Fund did not utilize the credit facility.

Notes to Financial Statements

August 31, 2012

Expense Reimbursement Plan

The Manager contractually agreed to reimburse the classes of the Fund to the extent that total annual fund operating expenses exceeded the Fund’s expense cap. During the year ended August 31, 2012, the Manager reimbursed expenses as follows:


Class	Expense Cap			Reimbursed Expenses		Expiration of Reimbursements
Institutional		0.90	%	$	135,178		2015
Y		0.99	%		36,620		2015
Investor		1.27	%		52,798		2015
A		1.39	%		34,998		2015
C		2.14	%		14,783		2015

Of these amounts, $67,217 is receivable from the Manager, as of August 31, 2012. 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 carryover of excess expenses potentially reimbursable to the Manager but not recorded as a liability is $146,216 expiring in 2014. 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, 2012 there has been $8,620 in sales commissions from the sale of A Class shares that were received by Foreside.

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, 2012 CDSC charges of $1,446 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 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 mutual funds are valued at the closing net asset value 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

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

(“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 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 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.

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2012

Common stocks, exchange-traded funds 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 net asset values (“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 Fund’s 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 transfers between levels of the Fund’s assets and liabilities. During the year ended August 31, 2012, there were no transfers into or out of any level for the Fund. As of August 31, 2012, 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 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, expense, 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, 2012, the Fund did not have any commission recapture.

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2012

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

Repurchase Agreements

Under the terms of a repurchase agreement, securities are acquired by a Fund from a securities dealer or a bank that are subject to resale at a later date. The agreement is backed by collateral in the form of securities and/or cash held by an eligible custody bank. All collateral is valued at cost, which approximates market value and is monitored daily by the investment advisor to make the determination that the collateral’s value exceeds the carrying value of the repurchase agreement plus accrued interest.

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

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2012

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, 2012 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.

5. Financial Derivative Instruments

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 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.

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.

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 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.

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 reflect market perception of 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, 2012 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.

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

Over-the-counter 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 sub-advisor provides a valuation, typically using its own proprietary models. Depending on the instrument and the terms of the transaction, the value of the derivative instrument can be determined by a pricing service or sub-advisor 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.

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.

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

Notes to Financial Statements

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.

The following is a summary of the fair valuations of the Fund’s derivative instruments categorized by risk exposure⁽¹⁾⁽³⁾:

6. Principal Risks

In the normal course of business the Fund trades financial instruments and enters 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 of a transaction to perform (credit and counterparty risk). See below for a detailed description of select principal risks.

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 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

Notes to Financial Statements

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.

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 Over-the-Counter (“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 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, 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 periods ended August 31, 2011 and 2012 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, 2012		Period ended August 31,2011
Distributions paid from:
*Ordinary income:**
Institutional Class	$	447	$	27
Y Class		165		—

Institutional Class		—		23
Y Class		—		—
Investor Class		—		—
A Class		—		—
C Class		—		—

Total distributions paid	$	1,000	$	51

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

As of August 31, 2012, the components of distributable earnings (deficit) on a tax basis were as follows (in thousands):


Cost basis of investments for federal income tax purposes	$	60,812

Unrealized appreciation		1,646
Unrealized depreciation		(311	)

Net unrealized appreciation (depreciation)		1,335

Undistributed ordinary income		850
Accumulated long-term gain(loss)		—
Other temporary differences		457

Distributable earnings (deficit)	$	2,642

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.

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2012

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, 2012 (in thousands):


Paid-in-capital	$ (10	)
Undistributed net investment income	1,060
Accumulated net realized gain(loss)	(1,050	)
Unrealized appreciation or (depreciation) of investments, futures contracts, option and swaption contracts and foreign currency translations	—

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 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, 2012.

Zebra Large Cap Equity and Zebra Small Cap Equity Funds

Investing in the securities of small capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies. At times, certain securities may have limited marketability and may be difficult to sell. The Fund may invest in future 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.

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 securities entails additional risk not associated with domestic securities, such as currency fluctuations, economic and political instability and differences in accounting standards. The Fund may invest in future 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 might 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

The Fund typically invests in a diversified portfolio of domestic and foreign high-yield, high-risk fixed income securities that are generally rated below investment-grade (such as BB or lower by Standard & Poor’s Ratings Services or Fitch ratings and/or Ba or lower by Moody’s Investors Service, Inc.) or deemed to be below investment-grade by the investment sub-advisor. These types of securities are commonly referred to as “high yield” or “junk” bonds. Investing in such 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. The principal risks of the Fund include also those derived from the investment in: foreign securities, emerging market securities, derivative securities including options and futures contracts (including options and futures contracts on stock indexes and currencies), forward contracts (including currency forward contracts), swap agreements and structured notes, Rule 144A securities, bank loans and senior loans and to a lesser extent equity securities including those of small and mid-capitalization companies.

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.

Dear Shareholders,

The volatile markets we experienced in the early part of 2012 have now settled into something more normal as summer draws to a close. In this rather unexciting market, from June 25 to the end of the reporting period, the Dow Jones Industrial Average didn’t have a single day in which it lost more than 1% of its value – a comforting environment for investors used to getting whipsawed on a daily basis. Against this backdrop, our actively managed funds have made solid gains.

For the period since its inception on May 29, 2012, the American Beacon The London Company Income Equity Fund (Institutional Class) returned 5.31%.

For the 12-month period ended August 31, 2012:

•

The American Beacon Zebra Large Cap Equity Fund (Institutional Class) returned 10.85%.

•

The American Beacon Zebra Small Cap Equity Fund (Institutional Class) returned 12.78%.

•

The American Beacon SiM High Yield Opportunities Fund (Institutional Class) returned 14.19%.

The first of the funds addressed in this annual report, American Beacon The London Company Income Equity Fund, is one of American Beacon’s newest offerings. The Fund is sub-advised by The London Company of Virginia, an equity manager with an impressive record of performance, and a firm we’re very proud to be associated with. Their work, fueled by more than three decades of investing experience, fits in very well with our desire to deliver the kind of consistency in performance that is important to our shareholders.

Thank you for your continued investment in 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,

Domestic Equity Market Overview

August 31, 2012 (Unaudited)

U.S. equity markets trended higher throughout much of the 12-month period that ended August 31, 2012 as the S&P 500 Index gained 17.3%. The low point for stocks during this period came at the end of the first month, on October 3, 2011, and, after that, they really never looked back. In March the market began a retrenchment that lasted a couple of months, but before August was over the S&P 500 had reached a new multi-year high.

Stocks were up across the board, with large-cap companies leading the way. Over the one-year period, the Russell 1000^® Index, which represents large-cap stocks, increased 17.3%, the Russell Midcap^® Index increased 13.3%, and the Russell 2000^® Index, representing small-caps, increased 13.4%.

The investor preference for larger capitalization stocks was reflected not just in the relative performance of the Russell 1000 Index versus the Russell 2000 Index, but also within the large-cap universe. Fifty percent of the return generated by the Russell 1000 came from the top 38% of the weight in the index.

Still, in recent years, correlation across equities has been very high. There was a period from August to October of last year when 90% of the stocks in the Standard & Poor’s 500 moved in the same direction on 31 trading days – or more than half the time.

The strong showing in equities came in spite of the fact that concerns surrounding European credit, U.S. debt and the presidential election dominated the year’s headlines. The U.S. economy continues its sluggish recovery from a difficult recession. The global economy is still slowly deleveraging, while the run-up of consumer debt in U.S. and government-sponsored debt in Europe has contracted credit and limited growth. Both the European Central Bank and the U.S. Federal Reserve have stepped in to provide additional liquidity, but the increased liquidity hasn’t resulted in significant gross domestic product (GDP) growth, with banks unwilling to lend and consumers unwilling to spend.

In response to the situation, the Federal Reserve recently announced a third round of quantitative easing (“QE”). The prior rounds of QE led to strong stock market performance, but did little to improve economic growth.

The uncertain nature of the economy both here and abroad led to some distinctly “risk-off” periods in the past year, when stocks with high betas or high default risk were the worst performers. These occurred in September 2011 and again in April and May of 2012, periods of increased tension over European debt. But otherwise, investors were well-rewarded for holding riskier equities.

In an interesting twist, many stocks that had been laggards in 2011 did a complete about-face in 2012, especially in the early going. Sears Holdings, for instance, fell 57% in 2011, but rose 117% in the first quarter of 2012; likewise, Bank of America was down 58% in 2011 but up 76% for the first quarter, and Netflix was down 61% in 2011 but up 72% for the first quarter.

With all the economic uncertainty and risk in the air, it’s not surprising that investor sentiment over that same period was generally muted, if not outright cautious. The number of investors surveyed by the American Association of Individual Investors who described themselves as bullish averaged 36%, which was down from nearly 42% during the prior 12-month period.

The following performance discussion covers the May 31, 2012 to August 31, 2012 period and does not cover performance from the May 29, 2012 inception through May 31, 2012.

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

Poor stock selection in the Information Technology, Financials, and Materials 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 Information Technology sector, the Fund was negatively impacted by holding Intel, which declined 3.2%. Federated Investors (+3.5%) hindered relative returns within the Financials sector while Albemarle was the primary driver of the negative impact within the Materials sector as the security declined 8.3%.

Several of the holdings within the Consumer Staples sector were a bright spot for returns. Tobacco companies Altria and Reynolds American both displayed strong results with gains of 9.1% and 12.2%, respectively. Wal-Mart also demonstrated strong results gaining 11.8%.

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 underweight to the Energy sector impeded results as it ranked as the best performing sector over the period (+12.7%). Additionally, overweighting the underperforming Consumer Staples (+6.1%) and Utilities (+2.5%) sectors also negatively impacted returns. Offsetting some of the headwinds from the Fund’s overall positioning was an underweight to the Industrials sector (+5.7%) as it was one of the weaker performers.

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

The Fund underperformed the Index as both stock selection and sector allocation detracted value relative to the Index.

From a stock selection standpoint, the Fund’s holdings in the Information Technology, Health Care and Consumer Discretionary sectors detracted the most value relative to the Index. In the Information Technology sector, Research in Motion (down 54.9%), Xerox (down 13.1%) and Anixter International (down 1.0%) had the largest negative impact on performance. HealthSouth (down 5.9%) and Humana (down 11.4%) were the largest detractors from the Fund’s returns in the Health Care sector. Shaw Communications (down 6.9%), Thomson Reuters (down 6.9%) and Nike (up 13.9%) hurt performance most in the Consumer Discretionary sector.

A significant underweight in Information Technology, the second best performing sector in the Index, detracted from the Fund’s performance through sector allocation. A more than three times overweight in the Utilities sector also hurt performance.

The sub-advisor continues to focus on uncovering investment opportunities through stock selection by investing in a portfolio of securities with strong exposure to the liquidity effect, balanced by fundamental information in order to capture the liquidity premium. This investment approach has typically resulted in a portfolio with lower Beta and volatility than the Index, although for this particular period the Beta of the portfolio was 1.0. Beta is a measure of the Fund’s systematic risk compared to the Index. A Beta of 0.85 would indicate that the Fund is expected to provide 15% less return when the Index increases and 15% better return when the Index decreases. Annualized volatility of the portfolio was 17.3% versus 17.1% for the Index. Much of the relative underperformance during this period was driven by a lack of exposure to the largest capitalization stocks within the benchmark. The Fund is underweight the largest stocks in the Russell 1000; for example the Fund had no exposure to Apple during the period and not holding that one stock accounted for almost one-third of the relative underperformance. The sub-advisor’s strategy, and its resulting characteristics, should allow the Fund to benefit over the longer term.

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.

Prior to the deduction of expenses, the Fund outperformed the Index as both stock selection and sector allocation added value relative to the Index.

Poor stock selection in the Consumer Discretionary and Materials sectors detracted from the Fund’s performance. Federal Mogul (down 37.8%) and Deer Consumer Products (down 44.8%) detracted from the Fund’s returns in the Consumer Discretionary sector.

A Beta of 0.85 would indicate that the Fund is expected to provide 15% less return when the Index increases and 15% better return when the Index decreases. For the twelve month period, the Beta of the Fund versus the Index was 0.93, with annualized volatility of 21.5% versus 22.9% for the Index. As a result of the lower Beta, the Fund slightly underperformed the Index. Much of this underperformance was driven by the limited upside capture generated by the Fund. The Fund only outperformed the Index on 5 of the 25 days when the market was up greater than 2%. On the other hand, the Fund outperformed the Index on 20 out of the 27 days when the market was down more than 2%.

High Yield Bond Market Overview

August 31, 2012 (Unaudited)

The high yield bond market performed very well for the year ended August 31, 2012, with the benchmark BofA Merrill Lynch U.S. High Yield Master II Index providing an annual return of 13.1%. This performance was in spite of the fact that the period got off to a very slow start, with a return of negative 3.5% in September 2011, as the recently resolved debt-ceiling struggle triggered new fears of a double-dip recession in the U.S. and there was growing concern about a Greek default and the Eurozone dissolving. But those issues quickly faded after the Federal Reserve and the European Central Bank announced programs to support their respective economies.

The positive movements from the central banks, combined with decent U.S. economic news, provided the wind behind a significant and lasting rally. The high yield market remained strong until May of this year, when a run on Greek banks stoked more fears of a default. But the ECB stepped in to remove the concern that the Euro might be dissolving, and the markets forged ahead.

As far as credit risk is concerned, lower-rated bonds fared better than higher-rated ones, but not by as much as would be expected, given the strong returns of the overall high yield market.

Among the industry sectors, consumer issues and especially housing performed well for the year. Basic industry commodities and energy performed relatively poorly, a result of the demand slowdown in China and Europe and concerns about excess supply.

The high yield market also benefitted from the drop in Treasury bond yields. Over the course of the year, the yield on the ten-year Treasury bond fell from 2.23% to 1.57% while the yield on the five-year bond dropped from 0.96% to 0.59%. With so little return from those benchmark government bonds, fixed-income investors looked to other instruments for greater yield, one key reason the year was so good for the category as a whole.

The BofA Merrill Lynch US High Yield Master II Index tracks the performance of U.S. dollar denominated below investment grade corporate debt publicly issued in the U.S. domestic market. Qualifying securities must have a below investment grade rating and an investment grade rated country of risk. In addition, qualifying securities must have at least one year remaining term to final maturity, a fixed coupon schedule and a minimum amount outstanding of $100 million. Defaulted securities and securities eligible for the dividends-received deduction are excluded from the Index. The Lipper High Current Yield Funds Index tracks the results of the 30 largest mutual funds in the Lipper High Current Yield Funds Category. Lipper is an independent mutual fund research and ranking service. One cannot directly invest in an index.

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 2.63%, 5.05%, 2.79%, 2.93%, and 4.03%, 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 categories and industry groups. To a lesser extent, the Fund’s relative weightings among credit quality categories and industry groups versus the Index also proved beneficial.

From a credit quality perspective, issue selection in the BB and B - 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 an industry standpoint, strong performance from issues in the Other-Finance, Services, Healthcare, and Gaming industries 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 Diversified Financial Services and Technology & Electronics industries.

From an industry allocation perspective, the Fund benefited from underweighting the Metals & Mining (up 3.2%) and overweighting the

American Beacon SiM High Yield Opportunities Fund^SM

Performance Overview

August 31, 2012 (Unaudited)

Healthcare industries (up 15.0%). The Fund’s Healthcare positioning is one of its larger overweight allocations, and the industry generated strong absolute returns gaining 15% for the period. However, underweighting the Automotive industry detracted from performance as the industry gained 17.6% for the period.

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 futures, options, or swaps; however, foreign currency transactions offset those gains.

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.

An obligation rated ‘AAA’ has the highest rating assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong. An obligation rated ‘AA’ by Standard & Poor’s differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong. An obligation rated ‘A’ by Standard & Poor’s is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong. An obligation rated ‘BBB’ by Standard & Poor’s exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation. Obligations rated ‘BB’, ‘B’, ‘CCC’, ‘CC’, and ‘C’ by Standard & Poor’s are regarded as having significant speculative characteristics. ‘BB’ indicates the least degree of speculation and ‘C’ the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

Fund Expenses

August 31, 2012 (Unaudited)

Fund Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments 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, 2012 through August 31, 2012.

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 that invest in the Fund through an 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.

Expenses are equal to the Fund’s annualized expense ratios for the six-month period 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 (366) to reflect the half-year period.

Expenses are equal to the Fund’s annualized expense ratios for the short period May 29, 2012 - August 31, 2012 multiplied by the average account value over the same period, multiplied by the number derived by dividing the number of days in the period (94) by days in the year (366) to reflect the half-year period.

Hypothetical Example for Comparison Purposes

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^SM

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of

American Beacon Zebra Large Cap Equity Fund, American Beacon Zebra Small Cap Equity Fund, American Beacon The London Company Income 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 Zebra Large Cap Equity Fund, American Beacon Zebra Small Cap Equity Fund, American Beacon The London Company Income Equity Fund, and American Beacon SiM High Yield Opportunities Fund (four of the funds comprising the American Beacon Funds) (collectively, the “Funds”) as of August 31, 2012, and the related statements of operations, statements of changes in net assets and 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 the Funds’ 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, 2012, 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 Zebra Large Cap Equity Fund, American Beacon Zebra Small Cap Equity Fund, American Beacon The London Company Income Equity Fund, and American Beacon SiM High Yield Opportunities Fund at August 31, 2012, and the results of their operations, the changes in their net assets, and the financial highlights for the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

⁽¹⁾

⁽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, 2012

1. Organization and Significant Accounting Policies

American Beacon Funds (the “Trust”), which is comprised of 24 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 Large Cap 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.

Class Disclosure

May 29, 2012 is the inception date for all classes of The London Company Income Equity Fund.

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
		Retirement Class		Investors investing through retirement plans
		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

Management has evaluated the implications of these changes and determined that the impact of the new guidance will only affect the disclosure requirements related to the financial statements. However, as the Funds did not hold any Level 3 investments as of August 31, 2012, the financial statement disclosures were not affected.

Notes to Financial Statements

August 31, 2012

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. 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, 2012 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		0.40	%	$	7	$	6	$	1
Zebra Large Cap Equity		0.38	%		59		51		8
Zebra Small Cap Equity		0.57	%		40		37		3
SiM High Yield Opportunities		0.50	%		617		555		62

Of these amounts $7,015, $8,888, $7,098, and $115,598 was payable to the Manager for The London Company Income Equity, Zebra Large Cap Equity, Zebra Small Cap Equity, and SiM High Yield Opportunities Funds, respectively, at August 31, 2012.

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, Investor, and Retirement Classes of the Funds and 0.40% of the average daily net assets of the A and C Classes of the Funds. Expenses for Retirement Classes for the year ended August 31, 2012 were less than $500.

Distribution Plans

The Funds, except for the Retirement, 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 Retirement, 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, 0.50% of the average daily net assets of the Retirement 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. Expenses for the Retirement Classes for the year ended August 31, 2012 were less than $500.

Service Plans

The Manager and the Trust entered into Service Plans that obligate the Manager to oversee additional shareholder servicing of the Y, Investor, Retirement, A, and C Classes. As compensation for performing the

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2012

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, 0.25% of the average daily net assets of the Retirement Class, and up to 0.375% of the average daily net assets of the Investor Class of the Funds. Expenses for the Retirement Classes for the year ended August 31, 2012 were less than $500.

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, 2012, the Zebra Large Cap Equity Fund borrowed from the American Beacon Short-Term Bond Fund on average $579,397 for 5 days at an average equity rate of 0.79% with interest charges of $63, the Zebra Small Cap Equity Fund borrowed from the American Beacon Short-Term Bond Fund on average $80,270 for 7 days at an average rate of 0.77% with interest charges of $9, and the SiM High Yield Opportunities Fund borrowed from the Short-Term Bond Fund on average $657,891 for 6 days at an average rate of 0.74% with interest charges of $80.

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, 2012, the Manager waived or reimbursed expenses as follows:

Of these amounts $62,591, $66,428, $59,548, and $26,248 was receivable from the Manager for The London Company Income Equity, Zebra Large Cap Equity, Zebra Small Cap Equity, and SiM High Yield Opportunities Funds, respectively, at August 31, 2012. 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 2015. The carryover of excess expenses potentially reimbursable to the Manager but not recorded as a liability for the Zebra Large Cap Equity, and the Zebra Small Cap Equity Funds, expiring in 2013 are $45,286 and $45,137, respectively. The carryover of excess expenses potentially reimbursable to the Manager but not recorded as a liability for the Zebra Large Cap Equity, the Zebra Small Cap Equity, and the SiM High Yield Opportunities Funds

expiring in 2014 are $93,890, $100,737, and $126,463, respectively. The London Company Income Equity Fund did not have carryover expenses from the prior year since its inception was during the current fiscal year. The 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 August 31, 2012, Foreside has collected $924, $1,469, $1,601, and $94,399 for The London Company Income Equity, Zebra Large Cap Equity, Zebra Small Cap Equity, and SiM High Yield Opportunities Funds, respectively from the sale of Class A Shares.

3. Security Valuation and Fair Value Measurements

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.

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

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.

American Beacon Funds^SM

Notes to Financial Statements

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 Net Asset Values (“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 market value. These investments are categorized as Level 2 of the fair value hierarchy.

Over-the-counter 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, 2012, there were no transfers into or out of any level. As of August 31, 2012, 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 net asset value. The value of the security may vary with market fluctuations.

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 Zebra Large Cap Equity and Zebra Small Cap Equity Funds normally will be declared and paid at least annually. Dividends from net investment income for The London Company Income Equity Fund will be declared and paid monthly. Dividends for the SiM High Yield Opportunities Fund will be declared daily, payable monthly. 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 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. For the year ended August 31, 2012 the Funds did not have commission recapture income.

Allocation of Income, Expenses, Gains, and Losses

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

4. Securities and other Investments

Repurchase Agreements

Under the terms of a repurchase agreement, securities are acquired by a Fund from a securities dealer or a bank that are subject to resale at a later date. The agreement is backed by collateral in the form of securities and/or cash held by an eligible custody bank. All collateral is valued at cost, which approximates market value, and is monitored daily by the investment advisor to make the determination that the collateral’s value exceeds the carrying value of the repurchase agreement plus accrued interest.

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

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2012

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, 2012 are disclosed in the Notes to the Schedules of Investments.

High-Yield Securities

5. Financial Derivative Instruments

Swap Agreements

The SiM High Yield Opportunities Fund may invest in swap agreements. Swap agreements are privately negotiated agreements between a Fund and a counterparty to exchange payments based on changes in the value of a specified index, rate or other instrument returns at specified, future intervals. A 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.

American Beacon Funds^SM

Notes to Financial Statements

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 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, a 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, a Fund would effectively add leverage to its portfolio because, in addition to its total net assets, a Fund would be subject to investment exposure up to the notional amount of the swap.

If a Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, a 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 a Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, a 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.

American Beacon Funds^SM

Notes to Financial Statements

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). A 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 a 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. A 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. A 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 Schedules 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 a 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, 2012 for which a Fund is the seller of protection are 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 a Fund for the same referenced entity or entities.

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.

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 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

A 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 a 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 a 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 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, a Fund’s investments in foreign currency denominated securities may reduce the returns of the Fund.

The market 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

A Fund will be exposed to credit risk on parties with whom it trades and will also bear the risk of settlement default. A Fund minimizes concentrations of credit risk by undertaking transactions with a large number of customers and counterparties on recognized and reputable exchanges. A 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, a 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 a Fund to counterparty risk, consist principally of cash due from counterparties and investments.

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 a 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

August 31, 2012

A 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. A 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 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 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 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.

International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreements”) govern OTC financial derivative transactions entered into by a 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 market 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 Schedules of Investments.

7. Federal Income and Excise Taxes

It is the policy of each Fund to qualify as a regulated investment company, 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, 2010, 2011 and 2012 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.

The Funds 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 were as follows (in thousands):

Distributable earnings or (deficits)	$	226		$	942		$	384		$	5,900

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, 2012 (in thousands):

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.

Disclosure Regarding the Board of Trustees’ Approval of the Management Agreement and Investment Advisory Agreements of the Funds (Unaudited)

At its May 9, 2012 meeting, the Board of Trustees (“Board”) considered: (1) the renewal of the Management Agreement between American Beacon Advisors, Inc. (the “Manager”) and the American Beacon Funds (“Beacon Trust”) on behalf of each of their series (collectively, the “Funds”); (2) the renewal of each investment advisory agreement between the Manager and a subadvisor (each an “Investment Advisory Agreement”); and 3) the approval of a new investment advisory agreement between the Manager and The London Company of Virginia, LLC (the “New Investment Advisory Agreement”). The Management Agreement, the Investment Advisory Agreements and the New Investment Advisory Agreement 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 and Lipper, Inc.

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 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. References below to each Fund’s Lipper peer group are to the group of comparable mutual funds included in the analysis provided by Lipper.

Provided below is an overview of the primary factors the Trustees considered at the Investment Committee meeting on May 4, 2012 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 9, 2012 meeting at which the Board considered the renewal of the Management Agreement and Investment Advisory Agreements. In addition, provided below is an overview of the primary factors considered by the Board in regard to the approval of the New Investment Advisory Agreement.

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 9, 2012 meeting, the Board considered each Fund’s investment management and subadvisory relationships separately.

Disclosure Regarding the Board of Trustees’ Approval of the Management Agreement and Investment Advisory Agreements of the Funds (Unaudited)

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 schedule; (5) whether fee 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 low 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 high 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 code 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 benchmark index(es) and peer group. The Board considered the information provided by Lipper regarding its independent peer selection methodology to select all peer groups and universes. The Board also considered the performance reports and discussions with management at Board and Committee meetings throughout the year. The Manager also noted that it generally was satisfied with the performance of the subadvisors. 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. The Board also considered that the Management Agreement for the Beacon Trust stipulates that, to the extent that a Fund invests all of its investable assets in another registered investment company (i.e., is a “Feeder Fund”), the Fund will not pay the Manager a management fee. 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 and to put in place new expense waivers and reimbursements for certain new classes of the Funds and new series of the Beacon Trust. The Board further considered that each subadvised Fund pays the Manager the amounts due to its subadvisors, and the Manager remits these amounts directly to the applicable subadvisors. The Board 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 and profitability 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 consider profitability data of the subadvisors 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.

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 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

Disclosure Regarding the Board of Trustees’ Approval of the Management Agreement and Investment Advisory Agreements of the Funds (Unaudited)

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 schedules for each Fund provides 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. The Board also considered that the Manager uses its proprietary American Beacon Large Cap Value Fund model to manage its collective investment trust.

In addition, the Manager noted that the Trusts 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 August 31, 2011.

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 peer universe median and/or benchmark index. References to the Lipper expense universe below are to the group of comparable mutual funds included in the analysis provided to the Trustees by Lipper. In reviewing the performance, the Trustees viewed longer-term performance over 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.

Additional Considerations and Conclusions with Respect to the American Beacon Zebra Large Cap Equity Fund

In considering the renewal of the Management Agreement for the American Beacon Zebra Large Cap Equity Fund, the Trustees considered the following additional factors: (1) the American Beacon Zebra Large Cap Equity Fund underperformed the peer universe median for the one-year period ended March 31, 2012; (2) the Fund underperformed its benchmark for the one-year period ended March 31, 2012; and (3) the expense ratio of the Institutional Class of the Fund ranked better than the median of its Lipper expense universe.

In considering the renewal of the Investment Advisory Agreement with Zebra Capital Management, LLC (“Zebra”), the Trustees considered the following additional factors: (1) Zebra underperformed the peer universe median for the one-year period ended March 31, 2012; (2) Zebra’s unique investment style; (3) the performance of Zebra with respect to the Fund’s assets it manages as compared to similarly managed accounts was not available because Zebra does not manage other accounts comparable to the Fund; (4) representations by Zebra regarding fee rates Zebra charges comparable clients; (5) whether Zebra uses Fund commissions to obtain proprietary or third-party research; and (6) the Manager’s recommendation to continue to retain the subadvisor.

Based on these and other considerations the Trustees (1) concluded that the fees paid to the Manager and the subadvisor under the Management and Investment Advisory Agreements are fair and reasonable; (2) determined that the American Beacon Zebra Large Cap Equity 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 Zebra Large Cap Equity Fund.

Additional Considerations and Conclusions with Respect to the American Beacon Zebra Small Cap Equity Fund

In considering the renewal of the Management Agreement for the American Beacon Zebra Small Cap Equity Fund, the Trustees considered the following additional factors: (1) the American Beacon Zebra Small Cap Equity Fund outperformed the peer universe median for the one-year period ended March 31, 2012; (2) the Fund outperformed its benchmark for the one-year period ended March 31, 2012; and (3) the expense ratio of the Institutional Class of the Fund ranked better than the median of its Lipper expense universe.

In considering the renewal of the Investment Advisory Agreement with Zebra, the Trustees considered the following additional factors: (1) Zebra outperformed the peer universe median for the one-year period ended March 31, 2012; (2) Zebra’s unique investment style; (3) the performance of Zebra with respect to the Fund’s assets it manages as compared to similarly managed accounts was not available because Zebra does not manage other accounts comparable to the Fund; (4) representations by Zebra regarding fee rates Zebra charges other comparable clients; (5) whether Zebra uses Fund commissions to obtain proprietary or third-party research; and (6) the Manager’s recommendation to continue to retain the subadvisor.

Based on these and other considerations the Trustees (1) concluded that the fees paid to the Manager and the subadvisor under the Management and Investment Advisory Agreements are fair and reasonable; (2) determined that the American Beacon Zebra Small Cap Equity 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 Agreement with respect to the American Beacon Zebra Small Cap Equity Fund.

Additional Considerations and Conclusions with Respect to the American Beacon SiM High Yield Opportunities Fund

In considering the renewal of the Management Agreement for the American Beacon SiM High Yield Opportunities Fund, the Trustees considered the following additional factors: (1) the American Beacon SiM High Yield Opportunities Fund outperformed the peer universe median for the one-year period ended March 31, 2012; and (2) the expense ratio of the Institutional Class ranked better than the median of its Lipper expense universe.

In considering the renewal of the Investment Advisory Agreement with Strategic Income Management, LLC (“SiM”), the Trustees considered the following additional factors: (1) SiM outperformed the peer universe median for the one-year period ended March 31, 2012; and (2) the Manager’s recommendation to continue to retain the subadvisor.

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.

Considerations With Respect to the Approval of the Appointment of The London Company of Virginia, LLC with Respect to the American Beacon The London Company Income Equity Fund

At the May 9, 2012 Board meeting, the Manager proposed that the Board approve The London Company of Virginia, LLC (“The London Company”) as an investment subadvisor to the American Beacon The London Company Income Equity Fund (the “Fund”). Prior to the meeting, the Board requested and reviewed information provided by The London Company in connection with its consideration of The London Company as an investment subadvisor to the Fund, and the Investment Committee of the Board met with representatives from The London Company. A discussion of the factors relating to the Board’s selection of The London Company and approval of the New Investment Advisory Agreement between the Manager and The London Company follows.

Nature, extent and quality of the services to be provided by The London Company. The Board considered information regarding The London Company’s principal business activities, its reputation, financial condition and overall capabilities to perform the services under the New Investment Advisory Agreement. In addition, the Board considered the background and experience of the personnel who will be assigned responsibility for managing the Fund. The Board also considered The London Company’s investment resources, infrastructure and the adequacy of its compliance program. In addition, the Board took into consideration the Manager’s recommendation of The London Company. The London Company also represented that its financial condition is adequate to provide high quality advisory services to the Fund and that its current staffing levels were adequate to service the Fund. Based on this information, the Board concluded that the nature, extent and quality of the advisory services to be provided by The London Company were appropriate for the Fund in light of its investment objective, and, thus, supported a decision to approve the New Investment Advisory Agreement.

Performance of The London Company. The Board evaluated The London Company’s historical investment performance record in managing assets under a similar investment mandate. In this regard, the Board evaluated the investment performance of The London Company Income Equity Composite (“Composite”) for the 2007 through 2011 periods, as compared to the S&P 500 Index (“Index”). The Board considered that the performance of the Composite outperformed the Index in 2008 and 2011 and underperformed the Index in 2007, 2009 and 2010. In light of all the information provided, the Board concluded that the historical investment performance record of The London Company supported the approval of the New Investment Advisory Agreement.

Comparisons of the amounts to be paid under the New Investment Advisory Agreement with those under contracts between The London Company and its other clients. In evaluating the New Investment Advisory Agreement, the Board reviewed the proposed advisory fee rate for services to be performed by The London Company on behalf of the Fund. The Board considered The London Company’s representation that, in addition to the Fund, The London Company has multiple clients that pay below The London Company’s standard annual fee rate. This information assisted the Board in concluding that The London Company’s advisory fee rate under the New Investment Advisory Agreement appeared to be within a reasonable range for the services to be provided to the Fund, in light of all the factors considered.

Extent to which economies of scale would be realized as the Fund grows and whether fee levels reflect these economies of scale for the benefit of Fund investors. The Board considered that the subadvisory fee rate that The London Company proposed for the Fund includes breakpoints that reflect economies of scale for the benefit of the Fund’s investors. Based on the foregoing information, the Board concluded that the breakpoints under the proposed fee schedule reflect economies of scale associated with the services to be provided by The London Company to the Fund.

Costs of the services to be provided and profits to be realized by The London Company and its affiliates from the relationship with the Fund. The Board did not consider the costs of the services to be provided and profits to be realized by The London Company from its relationship with the Fund, noting instead the arm’s-length nature of the relationship between the Manager and The London Company with respect to the negotiation of the advisory fee rate on behalf the Fund.

Benefits to be derived by The London Company from the relationship with the Fund. The Board considered The London Company’s statement that it may receive fall out benefits as a result of the advisory relationship with the Fund in the form of research provided by brokers from the generation of soft dollar credits. In this regard, the Board also considered The London Company’s

Disclosure Regarding the Board of Trustees’ Approval of the Management Agreement and Investment Advisory Agreements of the Funds (Unaudited)

representation that it uses soft dollars to acquire research products and services that fall within the safe harbor under Section 28(e) of the Securities and Exchange Act, as amended. Based on the foregoing information, the Board concluded that “fall-out” benefits that may accrue to The London Company were not a material factor in approving the New Investment Advisory Agreement.

Board’s Conclusion. Based on the various considerations described above, the Board, including a majority of Trustees who are not parties to the New Investment Advisory Agreement or “interested persons” of any such party, as that term is defined in the 1940 Act, concluded that the proposed advisory fee rate is reasonable and is in the best interests of the Fund and its shareholders and, as a result, approved the New Investment Advisory Agreement with respect to the Fund.
