Important Information: Investing in derivative instruments involves liquidity, credit, interest rate and market risks. Investments in high yield securities are subject to greater levels of credit, interest rate, market and liquidity risks than investment-grade securities. Although the Fund has a flexible approach to investing, diversification does not ensure against loss. Investing in foreign and emerging market securities may involve heightened risk due to currency fluctuations and economic and political risks. Please see the prospectus for a complete discussion of the Fund’s risks. There can be no assurances that the investment objectives of this Fund will be met.

Any opinions herein, including forecasts, reflect our judgment as of the end of the reporting period and are subject to change.

Dear Shareholders,

During much of the 12-month period ended August 31, 2015, U.S. stocks in general posted slight gains. U.S. equity markets have had to contend with slower economic growth, modestly higher-than-average valuations, and geopolitical and financial turmoil in Greece. Uncertainty over the timing of the U.S. Federal Reserve’s first interest rate increase since emergency lending rates were established during the financial crisis has also continued to weigh on markets. At the same time, the weakening of many currencies against the U.S. dollar took a toll on total returns for dollar-based investors in many global markets.

In the U.S. fixed-income market, long-duration Treasuries had a positive return and lower-quality bonds represented by high yield had negative returns for the period. For the period under review, the BofA Merrill Lynch 3-Month LIBOR Index returned 0.24%, the Barclays Capital U.S. Aggregate Index returned 1.56%, and the Citi World Government Bond Index—which tracks the performance of more than 20 government bond markets—returned -7.71%.

Our American Beacon Flexible Bond Fund is designed to provide stability, diversification and flexibility. Our investment approach allocates investments across a wide range of global investment opportunities in an effort to achieve positive total returns over a full market cycle regardless of market conditions.

For the 12 months ended August 31, 2015:

•

American Beacon Flexible Bond Fund (Investor Class) returned -3.01%.

Thank you for your continued interest in American Beacon Funds. We are pleased to have a broad range of products that cover the global equity and fixed income markets.

Global Bond Market Overview

August 31, 2015 (Unaudited)

During the 12-month period ended August 31, 2015, the biggest trouble spot for global growth has been the developing world, especially China. This group of economies represents almost 58% of global GDP and growth there has converged closer to the rate of U.S. growth than at any time since the late 1990s. Brazil, Russia, India and China (“BRIC countries”), which represent about 50% of this region, matched U.S. GDP last year. (In 2007, the U.S. economy was twice as big as the BRICs.) The collective trend in these countries is important. Monetary growth, when adjusted for inflation, is as low as it was in the late 1990s around the time of the emerging-market crisis, and their Purchasing Manager Indices point to recession. The BRICs are a part of the world in need of considerable reflation.

China’s monetary policy is dramatically behind the reflationary curve despite recent rate and reserve requirement cuts. Real interest rates remain elevated because inflation is falling faster than Chinese policymakers are cutting nominal rates as producers liquidate inventories, while deregulation has left corporate lending rates too high. Given the mounting evidence of slowing Chinese growth, the People’s Bank of China decided to weaken the renminbi to help stabilize the Chinese economy and re-establish strong growth. However, a weaker yuan may pump more deflationary pressures into the global economy, as it drives commodity prices down further and depresses emerging market currencies struggling to remain competitive, particularly in Asia.

In other emerging market countries, economic policy is hung up over inflation-pass-through anxiety tied to falling currencies. The decline in many of these currencies has matched the fall in their respective terms of trade. The latter, in turn, are linked to falling commodity prices. Tightening to prop up currencies weakened by a negative terms of trade shock is stagflationary. This stagflation is especially pronounced in Brazil where money growth is close to zero, and the economy is in recession but inflation remains sticky.

Part of the pressure on emerging-market currencies stems from generalized dollar strength along with expectations that the U.S. Federal Reserve (“Fed”) will raise rates this year. But Fed policy is data dependent and dollar strength has hurt the economy. In a world of low nominal

income growth, the surge in the U.S. dollar represents an internal tightening visible in reduced profit growth and lower corporate margins. S&P 500 Index revenue growth correlates closely with export growth, which is weak. Similarly, business sales growth correlates closely with producer price inflation, which has been weighed down by global deflationary trends. The Fed wants to end zero interest rate policy, but is struggling to do so with the current global backdrop. Therefore, the Fed has decided to delay the start to tightening given the potent deflationary pressures from outside the U.S. This imported global deflation may also anchor U.S. long yields. Investors are currently overreacting to a potential rate hike and pricing in a hard-landing in China. This uncertainty is causing the U.S. dollar to rally and emerging market currencies, stocks and commodities to sell off.

Europe’s economic fortunes seemed to be on the rise this year. Money growth has been a consistent and reliable indicator of future European growth, and it has been bolstered by a weaker euro, the end of austerity measures and European Central Bank (“ECB”) large-scale asset purchases. Early signs are visible that European credit growth has started to turn as well.

Nonetheless, it would be a mistake to call this a robust recovery or that deflation risks have passed. Market-based measures of inflation expectations have been fairly flat since April 2015, largely due to problematic negotiations with Greece, Chinese growth concerns and the speculation surrounding a Fed rate hike. Greece voted “No” in its austerity referendum, and the European Union (“EU”) gave Greece additional time to implement reform. Looking back, the effect of a “Grexit” is hard to assess. The direct effect on the EU’s Economic and Monetary Union seems small under most conventional guesses of how much it would contract because it is only 2% of eurozone GDP. However, a reasonable chance exists that the Greek economy could implode, which may carry with it more serious repercussions for the EU’s economy as a whole. In any event, it is clear that the ECB may likely double down its efforts to maintain stability and reflationary momentum.

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

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 1.25%, 1.30%, 1.44%, 1.69%, and 2.44%, 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.

Securities held in the Energy and Telecom sectors had a negative impact on performance over the annual period. Additionally, positions in Treasury Inflation Protected Securities were detrimental to Fund performance. Conversely, Fund holdings in the Finance sector, U.S. Treasuries, and Foreign Sovereign bonds all contributed to relative performance.

American Beacon Flexible Bond Fund ^SM

Performance Overview

August 31, 2015 (Unaudited)

The Fund’s holdings in bonds not rated by Standard & Poor’s detracted from performance during the period. Securities held by the Fund in the AA and A credit rating groups had a favorable impact on performance.

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. During the period, the Fund’s largest detractor was due to the use of futures, options, swaps, and foreign currency transactions.

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, 2015 (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, 2015 through August 31, 2015.

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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


	Beginning Account Value 3/1/15		Ending Account Value 8/31/15		Expenses Paid During Period* 3/1/15 - 8/31/15
Institutional Class
Actual	$	1,000.00	$	974.38	$	4.48

Hypothetical **	$	1,000.00	$	1,014.92	$	10.36

* Expenses are equal to the Fund’s annualized expense ratios for the six-month period of 0.90%, 0.99%, 1.27%, 1.29%, and 2.04% for the Institutional, Y, Investor, A, and C Classes respectively, multiplied by the average account value over the period, multiplied by the number derived by dividing the number of days in the most recent fiscal half-year (184) by days in the year (365) to reflect the half-year period.
** 5% return before expenses.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of

American Beacon Flexible Bond Fund:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of American Beacon Flexible Bond Fund (one of the funds constituting the American Beacon Funds) (the “Fund”), as of August 31, 2015, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of 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, 2015, 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 American Beacon Flexible Bond Fund at August 31, 2015, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of 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, 2015

1. Organization and Significant Accounting Policies

Effective April 30, 2015 American Beacon Advisors, Inc. (the “Manager”) became a wholly-owned subsidiary of Astro AB Borrower, Inc., which is indirectly owned by investment funds affiliated with Kelso & Company, L.P. and Estancia Capital Management, LLC, two prominent private equity firms. Prior to April 30 the Manager was a wholly-owned subsidiary of Lighthouse Holdings, Inc. which was indirectly owned by investment funds affiliated with Pharos Capital Group, LLC and TPG Capital, L.P., two leading private equity firms.

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

Class Disclosure

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


Class:		Offered to:
Institutional Class		Investors making an initial investment of $250,000
Y Class		Investors making an initial 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, which may include a front-end sales charge and a contingent deferred sales charge (“CDSC”)
C Class		General public and investors investing through an intermediary with applicable sales charges, which may include a CDSC

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 Pronouncement

In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-11, “Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures” (“ASU 2014-11”), that expanded secured borrowing accounting for certain reverse repurchase agreements. ASU 2014-11 also sets forth additional disclosure requirements for certain transactions accounted for as sales in order to provide financial statement users with information to compare to similar transactions accounted for as secured borrowings. ASU 2014-11 is effective prospectively for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Management is currently evaluating the impact, if any, of ASU 2014-11 on the Fund’s financial statement disclosures.

2. Transactions with Affiliates

Management Agreement

The Trust and the Manager are parties to a Management Agreement that obligates the Manager to provide or oversee the provision of all investment advisory and fund management services. Investment assets of the Fund are managed by multiple investment advisors which have entered into separate investment advisory agreements with the Manager and the Trust. 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. The Fund pays the unaffiliated investment advisors hired to direct investment activities of the Fund. Management fees paid by the Fund during the year ended August 31, 2015 were as follows (dollars in thousands):


Management Fee Rate	Management Fee	Amounts paid to Investment Advisors	Amounts Paid to Manager
0.60%	$1,418	$1,299	$119

Administration Agreement

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

Distribution Plans

The Fund, except for the A and C Classes of the Fund, has 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, 2015, the Fund did not utilize the credit facility.

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, 2015, the Manager reimbursed expenses as follows:


	Expense Cap
Class	9/1/14 - 8/31/15			Reimbursed Expenses		Expiration of Reimbursements
Institutional		0.90	%	$	580,034		2018
Y		0.99	%		137,152		2018
Investor		1.27	%		28,305		2018
A		1.29	%		76,501		2018
C		2.04	%		32,625		2018

Of these amounts, $84,171 is receivable from the Manager, as of August 31, 2015. The Fund has adopted an Expense Reimbursement Plan whereby the Manager may seek repayment of expenses reimbursed for a period of up to three years. However, reimbursement will occur only if the Class’s average net assets have grown or expenses have declined sufficiently to allow reimbursement without causing its expense ratio to exceed the previously agreed upon contractual expense limit. The reimbursed expenses listed above will expire in 2018. The carryover of excess expenses potentially reimbursable to the Manager, but not recorded as a liability is $378,404 and $854,833 expiring in 2016 and 2017, respectively. The Fund did not record a liability for potential reimbursements, due to the current assessment that a reimbursement is unlikely.

Sales Commissions

The Fund’s distributor, Foreside Fund Services, LLC (“Foreside”) may receive a portion of A Class sales charges from broker dealers and it may be used to offset distribution related expenses. For the year ended August 31, 2015 Foreside collected $2,515 from the sale of A Class Shares.

A contingent deferred sales charge (“CDSC”) of 0.50% will be deducted with respect to Class A Shares on certain purchases of $1,000,000 or more that are redeemed in whole or part within 18 months of purchase, unless waived as discussed in the Prospectus. Any applicable CDSC will be 0.50% of the lesser of the original purchase price or the value of the redemption of the Class A Shares redeemed. During the year ended August 31, 2015, there were no CDSC fees collected for the Fund.

A CDSC of 1.00% will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless waived as discussed in the Prospectus. Any applicable CDSC will be 1.00% of the lesser of the original purchase price or the value of the redemption of the Class C Shares redeemed. During the year ended August 31, 2015, CDSC charges of $2,602 were collected.

3. Security Valuation and Fair Value Measurements

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

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

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2015

Investments in open-end mutual funds are valued at the closing net asset value (“NAV”) per share of the mutual fund on the day of valuation.

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

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

For valuation purposes, the last quoted prices of non-U.S. equity securities may be adjusted under the circumstances described below. If the 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.

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

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.

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2015

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

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

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

Investments in registered open-end investment management companies will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy.

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.

Level 3 trading assets and trading liabilities, at fair value

The valuation techniques and significant inputs used in determining the fair values of financial instruments classified as Level 3 of the fair value hierarchy are as follows:

Securities and other assets for which market quotes are not readily available are valued at fair value as determined in good faith by the Board or persons acting at their direction and may be categorized as Level 3 of the fair value hierarchy.

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2015

for the entire day and no other market prices are available. The Board has delegated to the Manager the responsibility for monitoring significant events that may materially affect the fair values of a Fund’s securities or assets and for determining whether the value of the applicable securities or assets should be re-evaluated in light of such significant events.

The Board has adopted methods for valuing securities and other assets in circumstances where market quotes are not readily available, and has delegated the responsibility for applying the valuation methods to the Manager. For instances in which daily market quotes are not readily available, investments may be valued pursuant to guidelines established by the Board. In the event that the security or asset cannot be valued pursuant to one of the valuation methods established by the Board, the fair value of the security or asset will be determined in good faith by the Valuation Committee, generally based upon recommendations provided by the Manager.

When a Fund uses fair valuation methods applied by the Manager that use significant unobservable inputs to determine its NAV, the securities priced using this methodology are categorized as Level 3 of the fair value hierarchy. These methods may require subjective determinations about the value of a security. While the Trust’s policy is intended to result in a calculation of a Fund’s NAV that fairly reflects security values as of the time of pricing, the Trust cannot guarantee that values determined by the Board or persons acting at their direction would accurately reflect the price that a Fund could obtain for a security if it were to dispose of that security as of the time of pricing (for instance, in a forced or distressed sale). The prices used by a Fund may differ from the value that would be realized if the securities were sold.

For fair valuations using significant unobservable inputs, U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) requires a reconciliation of the beginning to ending balances for reported fair values that presents changes attributable to total realized and unrealized gains or losses, purchases and sales, and transfers in and out of the Level 3 category during the period. In accordance with the requirements of U.S. GAAP, a fair value hierarchy and Level 3 reconciliation, if any, have been included below.

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. As of August 31, 2015, 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 Fund. Interest income is earned from settlement date, recorded on the accrual basis, and adjusted, if necessary, for accretion of discounts and amortization of premiums. For financial and tax reporting purposes, realized gains and losses are determined on the basis of specific lot identification.

Currency Translation

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

Dividends to Shareholders

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

Commission Recapture

The Fund has established brokerage commission recapture arrangements with certain brokers or dealers. If a Fund’s investment advisor chooses to execute a transaction through a participating broker, the broker rebates a portion of the commission back to the Fund. Any collateral benefit received through participation in the commission recapture program is directed exclusively to the Fund. This amount is reported with the net realized gain in the Fund’s Statement of Operations, if applicable. For the year ended August 31, 2015, the Fund did have commission recapture.

Allocation of Income, Expenses, Gains, and Losses

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

Use of Estimates

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

Other

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

4. Securities and other Investments

Emerging Markets Debt

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

Repurchase Agreements

A repurchase agreement is a fixed income security in the form of an agreement between a Fund as purchaser and an approved counterparty as seller. The agreement is backed by collateral in the form of securities and/or cash transferred by the seller to the buyer to be held by an eligible third-party custodian.

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2015

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

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

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

Reverse Repurchase Agreements

Under a reverse repurchase agreement, the Fund sells securities and agrees to repurchase them at a mutually agreed upon date and price. At the time the Fund enters into a reverse repurchase agreement, it will establish a segregated account with the custodian containing liquid assets having at least equal value to the repurchase price.

Certificate of Deposit

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

Inflation-Indexed Bonds

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

Pay-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 pro rata adjustment from the unrealized appreciation or depreciation on investment to interest receivable in the Statement of Assets and Liabilities.

Restricted Securities

The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities may be sold privately, but are required to be registered or exempted from such registration before being sold to the public. Private placement securities are generally considered to be restricted except for those securities traded between qualified institutional investors under the provisions of Rule 144A of the Securities Act of 1933. Disposal of restricted securities may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult to achieve. Restricted securities outstanding as of August 31, 2015 are disclosed in the Notes to the Schedule of Investments.

High-Yield Securities

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

Real Estate Investment Trusts

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

Other Investment Company Securities and Other Exchange Traded Products

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

Mortgage-Related and Other Asset-Backed Securities

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

Mortgage-Backed Securities

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

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

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

Agency Mortgage-Backed Securities

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

Privately Issued Mortgage-Backed Securities

MBS held by a Fund may be issued by private issuers including commercial banks, savings associations, mortgage companies, investment banking firms, finance companies and special purpose finance entities (called special purpose vehicles or SPVs) and other entities that acquire and package mortgage loans for resale as MBS. These privately issued non-agency MBS may offer higher yields than those issued by government agencies, but also may be subject to greater price changes than governmental issues. Subprime loans refer to loans made to

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2015

borrowers with weakened credit histories or with a lower capacity to make timely payments on their loans. Alt-A loans refer to loans extended to borrowers who have incomplete documentation of income, assets, or other variables that are important to the credit underwriting processes. Non-conforming mortgages are loans that do not meet the standards that allow purchase by government-sponsored enterprises. MBS with exposure to subprime loans, Alt-A loans or non-conforming loans have had in many cases higher default rates than those loans that meet government underwriting requirements. The risk of non-payment is greater for MBS that are backed by mortgage pools that contain subprime, Alt-A and non-conforming loans, but a level of risk exists for all loans.

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

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

Asset-Backed Securities

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

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

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

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2015

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

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

Short Sales

The Fund may enter into short sale transactions. A short sale is a transaction in which a Fund sells a security it does not own in anticipation of a decline in the market price of the security. Securities sold in short sale transactions and the interest payable on such securities, if any, are reflected as a liability on the Statements of Assets and Liabilities. A Fund is obligated to deliver the security at the market price at the time the short position is closed. The risk of loss on a short sale transaction is theoretically unlimited, because there is no limit to the cost of replacing the security sold short, whereas losses from purchase transactions cannot exceed the total amount invested. As of August 31, 2015, short positions were held by the Fund.

Master Agreements

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

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

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

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

5. Financial Derivative Instruments

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

Options Contracts

The Fund may write (1) call and put options on futures, swaps (“swaptions”), securities, commodities or currencies it owns or in which it may invest and (2) inflation-capped options. Writing put options tends to increase the Fund’s exposure to unfavorable movements of the underlying instrument in exchange for an upfront premium. Writing call options tends to decrease the Fund’s exposure to favorable movements of the underlying instrument in exchange for an upfront premium. When the Fund writes a call, put, or inflation-capped option, an amount equal to the premium received is recorded as a liability and subsequently marked to market to reflect the current value of the option written. The purpose of inflation-capped options is to protect the buyer from inflation erosion above a certain rate on a given notional exposure. A floor can be used to give downside protection to investments in inflation-linked products. These liabilities are reflected as written options outstanding on the Statement of Assets and Liabilities. Certain options may be written with premiums to be determined on a future date. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against amounts paid on the underlying futures, swap, security or currency transaction to determine the realized gain or loss when the underlying transaction is sold. The Fund as a writer of an option has no control over whether the underlying instrument may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the instrument underlying the written option. There is the risk the Fund may not be able to enter into a closing transaction because of an illiquid market.

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

Options

For the year ended August 31, 2015, the Fund purchased/sold options primarily for return enhancement, hedging and exposing cash to markets.

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

Straddle Options

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

Swap Agreements

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

Swaps are marked to market daily based upon values from third party vendors or quotations from market makers to the extent available and the change in value, if any, is recorded as an unrealized gain or loss on the 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.

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

The maximum potential amount of future payments (undiscounted) that the Fund as a seller of protection could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement. Notional amounts of each individual credit default swap agreements outstanding as of August 31, 2015 for which the Fund is the seller of protection is disclosed in the Notes to the Schedule of Investments. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into by the Fund for the same referenced entity or entities.

For the year ended August 31, 2015, the Fund entered into credit default swaps primarily for return enhancement hedging and exposing cash to markets.

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

Interest Rate Swap Agreements

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

For the year ended August 31, 2015, the Fund entered into interest rate swaps primarily for return enhancement, hedging and exposing cash to markets.

Over-the-Counter Swap Agreements

OTC financial derivative instruments such as forward currency contracts, options contracts, interest rate, and credit default swap agreements derive their value from underlying asset prices, indices, reference rates and other inputs or a combination of these factors. These instruments are valued using evaluated prices furnished by a pricing service selected by the Board. In certain cases, when a valuation is not readily available from a pricing service, the Fund’s Manager may provide a valuation. Derivative instruments that use valuation techniques and inputs similar to those described above are normally categorized as Level 2 in the fair value hierarchy.

Total Return Swap Agreements

The Fund may enter into total return swaps in order to take a “long” or “short” position with respect to an underlying referenced asset. The Fund is subject to market price volatility of the underlying referenced asset. A total return swap involves commitments to pay interest in exchange for a market linked return based on a notional amount. To the extent that the total return of the security, group of securities or index underlying the transaction exceeds or falls short of the offsetting interest obligation, the Fund will receive a payment from or make a payment to the counterparty.

For the year ended August 31, 2015, the Fund didn’t have any total return swap agreements outstanding.

Inflation Swap Agreements

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

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

Notes to Financial Statements

August 31, 2015

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

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

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

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

Forward Foreign Currency Contracts

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

For the year ended August 31, 2015, the Fund entered into foreign currency exchange contracts primarily for return enhancement and hedging.

The Fund’s foreign currency contract notional dollar values outstanding fluctuate throughout the operating year as required to meet strategic requirements.

Futures Contracts

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

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

For the year ended August 31, 2015, the Fund entered into future contracts primarily for return enhancement, hedging and exposing cash to markets.

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

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

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.

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2015

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 number of customers and counterparties on recognized and reputable exchanges. The Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a financial derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings.

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

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

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

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

August 31, 2015

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.

Offsetting Assets and Liabilities

The Fund is party to enforceable master netting agreements between brokers and counterparties, such as ISDA, Master Repo Agreements and Master Forward Agreements which provide for the right to offset under certain circumstances. The Fund employs multiple money managers and counterparties and has elected not to offset qualifying financial and derivative instruments on the Statements of Assets and Liabilities, as such all financial and derivative instruments are presented on a gross basis. The impacts of netting arrangements that provide the right to offset are detailed below. Exchange traded futures and centrally cleared swap positions are not subject to master netting agreements, and as such are not included within the table. The net amount represents the net receivable or payable that would be due from or to the counterparty in the event of default. Exposure from borrowings and other financing agreements such as repurchase agreements can only be netted across transactions governed by the same Master Agreement with the same legal entity. All amounts reported below represent the balance as of the report date, August 31, 2015 (in thousands).

7. Federal Income and Excise Taxes

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

The Fund does not have any unrecognized tax benefits in the accompanying financial statements. The tax years for the periods ended August 31, 2012, 2013, 2014, and 2015, 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.

Undistributed ordinary income		7,191
Accumulated capital gain (loss)		(11,403	)
Other temporary differences		(66	)

Distributable earnings (deficit)	$	(15,969	)

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

Due to inherent differences in the recognition of income and expenses and realized gains and (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, paydowns, swap income, and distributions that have been reclassified as of August 31, 2015 (in thousands):

Disclosure Regarding the Board of Trustees’ Approval of the Management

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

At an in-person meeting held on November 12, 2014, telephonic meetings held on November 26, 2014 and December 6, 2014 and an in-person meeting held on December 10, 2014 (collectively, the “Board Meetings”), the Board of Trustees (“Board”) considered the approval of: (1) a new Management Agreement (“New Management Agreement”) among American Beacon Advisors, Inc. (“Manager”) and the American Beacon Funds (“Trust”) on behalf of the American Beacon Flexible Bond Fund (“Fund”); (2) a new Investment Advisory Agreement among the Manager, Pacific Investment Management Company LLC (“PIMCO”) and the Trust, on behalf of the und; (3) a new Investment Advisory Agreement among the Manager, Brandywine Global Investment Management, LLC (“Brandywine”) and the Trust, on behalf of the Fund; and (4) a new Investment Advisory Agreement among the Manager, GAM International Management Ltd. (“GAM”) and the Trust, on behalf of the Fund (collectively, the “New Advisory Agreements”). Collectively, PIMCO, Brandywine and GAM are hereinafter referred to as the “Sub-Advisors.”

The Board meetings were held for the Trustees to consider the New Management Agreement and New Advisory Agreements (“New Agreements”) because, on November 20, 2014, Lighthouse Holdings Parent, Inc. (“LPHI”), the indirect parent company of the Manager, entered into an Agreement and Plan of Merger pursuant to which LHPI agreed to be acquired by Kelso Investment Associates VIII, L.P., KEP VI, LLC and Estancia Capital Partners L.P., investment funds affiliated with Kelso & Company, L.P. (“Kelso”) and Estancia Capital Management, LLC (“Estancia”) (collectively, the “Purchasers”), which are private equity firms (“Transaction”). As required by the Investment Company Act of 1940, as amended (“1940 Act”), the current Management Agreement (“Current Management Agreement”) among the Manager and the Trust on behalf of the Fund and the current Investment Advisory Agreements (“Current Advisory Agreements”) among the Manager, the Trust, on behalf of the Fund, and each of PIMCO, Brandywine and GAM, provide for their automatic termination in the event of an assignment. As a result, the Current Management Agreement and each Current Advisory Agreement (“Current Agreements”) would terminate upon the closing of the Transaction. (The Transaction closed on April 30, 2015).

The Board focused on the effect that the Transaction would have on the Manager and the Fund. Additionally, the Board considered that it had requested and evaluated the information relevant to the renewal of the Current Management Agreement and Current Advisory Agreements at in-person meetings held in May and June 2014. The Manager represented to the Board that there had been no material changes or developments relating to the Manager or any of the Sub-Advisors since the May and June 2014 meetings, other than the changes or developments subsequently reported to the Board or discussed in the due diligence materials submitted to the Trustees in connection with the Transaction. In light of the proximity of the Board’s consideration of the renewal or approval of the Current Agreements, and the Board’s ongoing due diligence review in connection with the Transaction, the Board determined that it was not necessary to repeat certain aspects of the review conducted in connection with the approvals in the past year.

In connection with the Board Meetings, the Trustees received and evaluated such information as they deemed necessary to their consideration of the New Agreements. The information requested on behalf of the Board included, among other information, the following:

•

a description of the Transaction, the effect of the Transaction on the Manager, the Trust and the Board, and any proposed changes to the Trust, its service providers, the Fund’s fee structures, fee waivers, and other information;

•

a description of any anticipated significant changes, if any, to principal activities, personnel, services provided to the Fund, or any other area, including how these changes might affect the Fund;

•

information regarding the financial resources of the Purchasers and the Manager’s capital structure after the Transaction, including confirmation that the Manager’s financial condition would not raise concerns that the Manager would be unable to continue providing the same scope and quality of services to the Fund;

•

information regarding the Manager’s due diligence, bidding and selection process with respect to the Purchasers;

•

information regarding the structure of the relationship between Kelso and Estancia and the role that each would assume in advance of and after the Closing;

•

information regarding each Purchaser’s ownership structure and key personnel, including information regarding affiliations of the Purchaser and the Manager after the Transaction;

•

information regarding each Purchaser’s asset management experience, including the experience of the Purchasers’ key personnel relating to the management of investment companies registered under the 1940 Act;

•

the Purchasers’ business plans with respect to the Manager after the Transaction;

•

information regarding the extent to which the Purchasers expect to be involved in the Manager’s day-to-day operations and the persons to whom the Manager’s key personnel will report;

•

information regarding any anticipated impact that the Transaction might have on the Manager’s compliance activities or the resources available to the Fund’s Chief Compliance Officer;

•

a discussion of any potential material changes to the Current Agreements;

•

a description of any expected changes in distribution or marketing efforts and strategies for the Fund as a result of the Transaction;

•

information regarding whether the Purchasers or the Manager anticipated proposing any changes to the membership of the Board;

•

a discussion of the length of the Purchasers’ anticipated ownership of the Manager and the expected duration of the investment funds financing the Transaction;

•

information regarding the ownership and investment of management personnel in the Manager;

•

information regarding the Manager’s employee equity incentive plan after the Closing;

•

a summary of any material past, pending or anticipated litigation or regulatory proceedings involving the Purchasers, or their personnel;

•

verification of the continuation of the Manager’s insurance coverage after the Transaction with regard to the services provided to the Fund; and

•

in-person presentations by and discussions with the Manager and representatives of the Purchasers regarding the Transaction.

Disclosure Regarding the Board of Trustees’ Approval of the Management

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

The Board also considered information that had been provided to the Board by the Manager and the Sub-Advisors for the May and June 2014 meetings in connection with the renewal of the Current Agreements.

Provided below is an overview of the primary factors the Trustees considered at the Board Meetings. The Board did not identify any particular information that was most relevant to its consideration to approve the New Agreements, and each Trustee may have afforded different weight to the various factors. In connection with the approval process for the New Agreements, the Trustees received advice from their legal counsel detailing the Board’s responsibilities pertaining thereto. Legal counsel to the non-interested Trustees provided the Board with a memorandum regarding its responsibilities pertaining to the approval of the New Agreements. Based on its evaluation, the Board unanimously concluded that the terms of the New Agreements were reasonable and fair and that the approval of the New Agreements was in the best interests of the Fund and its shareholders.

In determining whether to approve the New Agreements, the Trustees considered the best interests of the Fund. The Board considered the Fund’s investment management and sub-advisory relationships separately. In each instance, the Board considered its review of the Current Agreements in May and June 2014, and the information received in November and December 2014 with respect to, among other things, the following factors: (1) the nature, extent and quality of the services provided; (2) the investment performance of the Fund and, as applicable, each Sub-Advisor for the Fund; (3) the costs incurred by the Manager in rendering services to the Fund and its resulting profits or losses; (4) comparisons of services and fee rates with contracts entered into by the Manager or a Sub-Advisor or their affiliates with other clients (such as pension funds and other institutional clients); (5) the extent to which economies of scale have been taken into account in setting each fee rate schedule; (6) whether fee rate levels reflect these economies of scale for the benefit of Fund investors; and (7) any other benefits derived or anticipated to be derived by the Manager or a Sub-Advisor from its relationship with the Fund. The Trustees posed questions to various management personnel of the Manager and the Purchasers regarding certain key aspects of the materials submitted in support of the approval of the New Agreements.

Nature, Extent and Quality of the Services Provided. With respect to the approval of the New Agreements, the Board considered that the New Agreements provide for the Manager and each Sub-Advisor to provide the same services to the Fund on substantially the same terms as the Current Agreements. The Board considered representations by the Manager and/or Purchasers that the Transaction will not result in any changes to the manner in which the Fund’s assets are managed. The Board also considered representations by the Manager and/or Purchasers that the Transaction will not result in any adverse impact or changes to: the personnel involved in the management of the Fund; the Manager’s disciplined investment approach and goal to provide consistent above average long-term performance at a lower than average cost; the Manager’s continuing efforts to enhance distribution of the Fund’s shares and add new series to the Trust and share classes to the Fund’s product line; the adequacy of the Manager’s financial condition; the Manager’s day-to-day operations; the Manager’s compliance activities or the resources available to the Trust’s Chief Compliance Officer; or the Fund’s service providers or Sub-Advisors. The Board also considered the Manager’s representation that there had been no material changes or developments regarding the Manager or the Sub-Advisors since the Board’s consideration of the Current Agreements in May and June 2014 that had not previously been reported to the Board. The Board also considered information regarding the post-closing capitalization of the Purchasers and the Purchasers’ long-term business goals with regard to the Manager and the Manager’s activities with respect to the Trust, which are consistent with the Manager’s current goals. 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 the Sub-Advisors were appropriate for the Fund and, thus, determined to approve the New Agreements for the Fund.

Investment Performance. The Board considered its review of the comparative information regarding the Fund’s investment performance relative to its benchmark index(es) and peer group in connection with the renewal of the Current Agreements. The Board also considered the performance reports and discussions with management at Board and Committee meetings since June 2014. The Manager also noted that it generally was satisfied with the performance of the Sub-Advisors.

Costs of the Services to be Provided to the Fund and the Projected Profits to be Realized by the Manager from its Relationship with the Fund. In analyzing the cost of services and profitability of the Manager with respect to the Fund, the Board considered that the Transaction would result in no changes to the fees charged to the Fund or the Manager’s fee waivers currently in place with respect to the Fund. Additionally, the Board noted that there had been no material changes in this regard since its consideration of the Current Agreements in May and June 2014. Based on the foregoing information and the Board’s considerations in connection with the renewal of the Current Agreements in May and June 2014, the Board concluded that the profitability levels were reasonable in light of the services performed by the Manager. The Board did not consider the costs of the services to be provided and profits to be realized by each Sub-Advisor from its relationship with the Fund, noting instead the substantially arm’s-length nature of the relationship between the Manager and each Sub-Advisor with respect to the negotiation of the advisory fee rate on behalf of the Fund.

Economies of Scale and Whether Fee Levels Reflect Economies of Scale. In considering the reasonableness of the management fees, the Board considered that the Fund would pay the same fee rates to the Manager under the New Management Agreement as the Fund currently pays under the Current Management Agreement. The Board also considered that the Fund would pay the same investment advisory fee rate to each Sub-Advisor under the New Advisory Agreements as the Fund pays under the Current Advisory Agreements. Based on the foregoing information and the Board’s considerations in connection with the renewal of the Current Agreements in May and June 2014, the Board concluded that the Manager’s fee schedule for the Fund, and each of PIMCO’s, Brandywine’s and GAM’s fee schedules for the Fund, provide for a reasonable sharing of benefits from any economies of scale with the Fund.

Benefits Derived by the Manager from Relationship With the Fund. The Board considered that the “fall-out” or ancillary benefits that accrue to the Manager and/or a Sub-Advisor as a result of its advisory relationship with the Fund would not change as a result of the Transaction. Based on the foregoing information and the Board’s considerations in connection with the renewal of the Current Agreements in May and June 2014, the Board concluded that the potential benefits accruing to the Manager under the New Management Agreement and the Sub-Advisors under the New Advisory Agreements, by virtue of the Manager’s, PIMCO’s, Brandywine’s and GAM’s relationship with the Fund, appear to be fair and reasonable.

Agreement and Investment Advisory Agreements of the Funds (Unaudited)

Board’s Conclusion. Based on the various considerations described above, the Board, including a majority of Trustees who are not “interested persons” of the Fund, the Manager, PIMCO, Brandywine, or GAM, as that term is defined in the 1940 Act, concluded that the management and investment advisory fee rates to be paid by the Fund are fair and reasonable and that the approval of the New Agreements is in the best interests of the Fund, and approved the New Agreements.

THE LONDON COMPANY INCOME EQUITY FUND

Investing in small- and medium-capitalization stocks may involve greater volatility and lower liquidity than larger company stocks. Investing in foreign securities may involve heightened risk due to currency fluctuations and economic and political risks. Investing in dividend-paying stocks may result in less earnings growth or capital appreciation than investing in non-dividend paying stocks. The use of fixed-income securities entails interest rate and credit risks. Because the Fund may invest in fewer issuers than a more diversified portfolio, the fluctuating value of a single holding may have a greater effect on the value of the Fund. The use of futures contracts for cash management may subject the Fund to losing more money than invested.

ZEBRA GLOBAL EQUITY FUND

Investing in medium-capitalization stocks may involve greater volatility and lower liquidity than larger company stocks. At times, certain securities may have limited marketability and may be difficult to sell. Investing in foreign securities may involve heightened risk due to currency fluctuations and economic and political risks. The use of futures contracts for cash management may subject the Fund to losing more money than invested. The Fund may participate in a securities lending program.

ZEBRA SMALL CAP EQUITY FUND

Investing in small-capitalization stocks may involve greater volatility and lower liquidity than larger company stocks. Investing in foreign securities may involve heightened risk due to currency fluctuations and economic and political risks. At times, certain securities may have limited marketability and may be difficult to sell. The use of futures contracts for cash management may subject the Fund to losing more money than invested. The Fund may participate in a securities lending program.

SiM HIGH YIELD OPPORTUNITIES FUND

Investments in high yield securities are subject to greater levels of credit, interest rate, market and liquidity risks than investment-grade securities. Investing in foreign and emerging market securities may involve heightened risk due to currency fluctuations and economic and political risks. Investing in derivative instruments involves liquidity, credit, interest rate and market risks.

Please see the prospectus for a complete discussion of the Funds’ risks. There can be no assurances that the investment objectives of these Funds will be met.


American Beacon Funds		August 31, 2015

Dear Shareholders,

During much of the 12-month period ended August 31, 2015, uneven global economic growth, declining oil prices and disparate central bank policies set the stage for mixed returns in all markets. Uncertainty over the timing of the U.S. Federal Reserve’s first interest rate increase since emergency lending rates were established during the 2008 financial crisis also weighed on domestic equity markets, and the substantial weakening of many currencies against the U.S. dollar took a toll on total returns for dollar-based investors in numerous global markets.

On August 24, 2015, the Dow Jones industrial average plunged 1,000 points during the course of the day. Although it rebounded to only lose roughly half that amount at market close, investors were unmistakably concerned about the global economy, especially China’s slowdown. However, following better-than-expected second quarter GDP growth results, many of the major U.S. and European indexes found their way back into the black that week after the Dow, the S&P 500 Index and the Nasdaq composite moved clear of a “correction,” which is defined as a drop of 10% or more from a recent high.

We are proud to offer a broad range of funds to help investors navigate the economic storms and market downturns in the U.S. and abroad. Our years of experience evaluating sub-advisors has led us to identify and partner with several asset managers who have adhered to their disciplined processes for many years and through a variety of economic and market conditions.

For the 12 months ended August 31, 2015:

•

American Beacon The London Company Income Equity Fund (Investor Class) returned 0.71%.

•

American Beacon Zebra Global Equity Fund (Investor Class) returned -6.84%.

•

American Beacon Zebra Small Cap Equity Fund (Investor Class) returned 0.29%.

•

American Beacon SiM High Yield Opportunities Fund (Investor Class) returned -1.14%.

Best Regards,

Gene L. Needles, Jr.

President

Domestic Equity Market Overview

August 31, 2015 (Unaudited)

U.S. economic news was generally positive during the 12-month period ended August 31, 2015, including rising consumer confidence, higher consumer spending, lower unemployment and a stable/improving housing market. U.S. gross domestic product (“GDP”) was positive each quarter over the past year with first quarter 2015 being the weakest. Poor weather, a strong dollar and a West Coast dock strike had a negative effect on first quarter 2015 results. GDP growth was more than 2% for the rest of the period.

The U.S. equity markets were roughly flat for the 12-month period. Stocks traded in a fairly narrow range most of the year, but then declined in August. Investors turned more negative late in the summer of 2015, reflecting a slowdown in the Chinese economy, the significant drop in oil prices and constant worries about when the U.S. Federal Reserve would finally start raising rates. While the U.S. economy remains in good shape, much of the rest of the world looks weaker.

Overall, for the period under review, there was very little differentiation across market-cap ranges. Most of the major indexes posted slightly positive gains: The S&P 500 Index increased 0.5%, the Russell 1000 Index increased 0.4%, the small-cap Russell 2000 Index rose 0.03% and the broader Russell 3000 Index rose 0.4%. Growth stocks outperformed value as the Russell 1000 Growth Index rose 4.3% while the Russell 1000 Value Index declined 3.5%. The best performing sectors were Health Care and Consumer Discretionary, while Energy and Materials lagged the overall market.

Please note that the recent growth in the stock market has helped to produce short-term returns that are not typical and may not continue in the future. Performance shown is historical and is not indicative of future returns. Investment returns and principal value will vary, and shares may be worth more or less at redemption than at original purchase. Performance shown is calculated based on the published end of day net asset values as of date indicated, and current performance may be lower or higher than the performance data quoted. To obtain performance as of the most recent month end, please visit www.americanbeaconfunds.com or call 1-800-967-9009. Fund performance in the table above does not reflect the deduction of taxes a shareholder would pay on distributions or the redemption of shares. A Class shares have a maximum sales charge of 5.75%. The maximum contingent deferred sales charge for the C Class is 1.00% for shares redeemed within one year of the date of purchase.

A portion of the fees charged to the Institutional, Y, A, and C Classes of the Fund was waived from 2012 through 2014 and partially recovered in 2015. Performance prior to waiving fees was lower than the actual returns shown from 2012 through 2014. A portion of the fees charged to the Investor Class of the Fund was waived in 2012 and 2013 and partially recovered in 2014 and 2015. Performance prior to waiving fees was lower than actual returns shown in 2012 and 2013.

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 0.83%, 0.90%, 1.07%, 1.29%, and 2.03%, 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 excess performance relative to the Index was attributable to strong security selection among the various economic sectors. While security selection contributed to performance, sector allocation slightly detracted from the Fund’s returns.

American Beacon The London Company Income Equity Fund^SM

Performance Overview

August 31, 2015 (Unaudited)

From a security selection standpoint, the Fund’s holdings in the Consumer Discretionary and Consumer Staples sectors contributed most to performance adding approximately 335 (3.35%) and 265 (2.65%) basis points, respectively. In the Consumer Discretionary sector, Hasbro (up 45.8%), Lowes (up 32.7%) and Carnival (up 33.2%) were the largest contributors. Reynolds American (up 51.6%) and Altria Group (up 29.0%) contributed most to performance in the Consumer Staples sector. The Fund’s Energy and Industrials sectors also benefited performance, adding more than 90 (0.90%) basis points each. In the Energy sector, not owning Exxon Mobil, Apache or Anadarko Petroleum, which were down 21.9%, 54.8% and 35.7%, respectively, in the Index, positively impacted performance. General Dynamics (up 17.3%) was the largest contributor in the Industrials sector. Not owning Caterpillar, which was down 27.6% in the Index, also contributed to the Fund’s returns.

The aforementioned good performance was somewhat offset by poor stock selection in the Utilities and Telecommunication Services sectors. In the Utilities sector, not owning PG&E or Public Service Enterprise, which were up 10.6% and 11.9%, respectively, in the Index, detracted relative value. In the Telecommunication Services sector, the Fund’s absence from AT&T and T-Mobile, which were up 0.3% and 31.7%, respectively, in the Index, also negatively impacted performance.

The Fund’s overweight position in Materials, one of the poorer performing sectors in the Index, detracted relative value through sector allocation. Significant underweight positions in Financials and Health Care, the two best performing sectors in the Index, also detracted from the Fund’s returns. The aforementioned underperformance was mostly negated by the Fund’s large underweight in Energy, the worst performing sector in the Index, which added relative value. An overweight in the Consumer Staples sector also contributed to the Fund’s returns.

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

Global Equity Market Overview

August 31, 2015 (Unaudited)

Global equity markets, as represented by the MSCI World Index, declined 4.1% during the 12-month period ended August 31, 2015. The period was bookended by steep sell-offs in September-October 2014 and then again in mid-August 2015. In between, the MSCI World Index peaked at an all-time high on May 21, 2015.

The September-October 2014 drop was steep and coincided with the beginning of a more persistent decline in the price of oil. However, the onset of earning reports in mid-October 2014 gave investors a reason to buy equities, and stock prices quickly recovered. Indeed, for the full month of October 2014, the MSCI World Index ended slightly positive, resulting in a pronounced V-shaped price pattern. Oil prices did not enjoy the same resiliency and continued to fall. During the 12-month period, the price of Brent Crude Oil dropped from approximately $103 per barrel to approximately $49 per barrel.

More recently, the August 2015 weakness in equities was precipitated by concerns that global economic growth was in jeopardy and, specifically, that China’s economy was headed for a hard landing. The Chinese government’s devaluation of the yuan, followed by its subsequent support efforts, left investors questioning whether Chinese authorities are equipped to manage the world’s second largest economy.

As would be expected with the precipitous fall in oil prices, the Energy sector suffered the most during the period under review. Materials stocks also were hurt, led down by global mining firms like BHP Billiton and Freeport McMoran. On the positive side of the ledger, Health Care stocks were driven higher by a fair amount of mergers and acquisitions in the sector.

In reviewing global equity returns for the period, one element particularly stands out: the poor performance of value versus growth. Globally, value underperformed growth by 846 basis points (-8.46%) since September 2014. An even greater value/growth differential could be observed in the U.S., Europe and the U.K. Of the four largest developed equity markets, it was only in Japan that value outperformed growth and then only by a relatively modest 246 basis points (2.46%).

American Beacon Zebra Global Equity Fund^SM

Performance Overview

August 31, 2015 (Unaudited)

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 2.56%, 2.51%, 2.88%, 3.03%, and 3.72% 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.

From a stock selection standpoint, the Fund underperformed the Index as holdings in the Consumer Discretionary and Information Technology sectors detracted approximately 115 (1.15%) and 100 (1.00%) basis points, respectively, from performance. Viacom (down 48.4%) was the largest detractor in the Consumer Discretionary sector. Not owning Amazon.com, which was up 51.3% in the Index, also detracted from the Fund’s returns. In the Information Technology sector, not owning Apple or Visa, which were up 11.9% and 35.2%, respectively, in the Index, hurt performance. The aforementioned poor performance was somewhat offset by good stock selection in the Financials sector which added relative value. In the Financials sector, SEI Investments (up 34.9%) was the largest contributor. Not owning Banco Santander, which was down 34.1% in the Index, also positively impacted performance.

From a country allocation perspective, the Fund’s absence from Singapore and Norway, as well as its position in the United States, added relative value. The Fund’s lack of exposure to Denmark and Italy detracted from performance.

The sub-advisor continues to focus on uncovering opportunities by investing in a portfolio of securities that are generally less popular with investors but nevertheless have strong fundamental characteristics. At the same time, the portfolio will be underweight stocks that are heavily followed but have weak fundamentals. This contrarian style has tended to result in a portfolio with very good risk-adjusted returns over time. This emphasis on companies with good fundamentals can be observed through traditional measures of value. For example, the portfolio consistently exhibits price-earnings ratios (both forward and trailing) lower than the Index.

The predicted beta for the portfolio as of August 31st was 0.97, and over the past 12-months, the daily realized beta has been 0.95. Beta is a measure of the Fund’s systematic risk compared to the Index. For example, a beta of 0.90 would indicate that the Fund is expected to provide a 10% less return when the Index increases and a 10% better return when the Index decreases. The portfolio continues to have exposure to factors that the sub-advisor actively seeks. For example, the portfolio has negative exposure to stocks that are more popular (traded more frequently) and positive exposure to stocks with good quality and value characteristics. The sub-advisor’s strategy, and its resulting characteristics, should benefit the Fund’s performance over the longer term.

American Beacon Zebra Small Cap Equity Fund^SM

Performance Overview

August 31, 2015 (Unaudited)

The Fund outperformed the Index as both stock selection and sector allocation added relative value. From a stock selection standpoint, holdings in the Energy, Financials and Materials sectors contributed most to performance. In the Energy sector, not owning Helix Energy Solutions Group or Bonanza Creek Energy, which were down 74.6% and 87.5%, respectively, in the Index, positively impacted performance. In the Financials sector, Credit Acceptance (up 66.4%), Walker & Dunlop (up 79.2%) and Heartland Financial USA (up 55.2%) were the largest contributors. Not owning U.S. Silica Holdings or AK Steel Holdings, which were down 71.6% and 71.7%, respectively, in the Index, added relative value in the Materials sector. The Fund’s position in Innospec (up 13.1%) also contributed to performance. The aforementioned good performance was slightly offset by the Fund’s poor stock selection in the Health Care and Industrials sectors. In the Health Care sector, PDL BioPharma (down 38.1%) was the largest detractor. Not owning Anacor Pharmaceuticals, which was up 459.9% in the Index, also negatively impacted performance. West Corporation (down 17.7%), Altisource Portfolio Solutions (down 40.6%) and PHI (down 41.2%) detracted from the Fund’s returns in the Industrials sector.

The Fund’s underweight positions in Energy and Materials, the two worst performing sectors in the Index, contributed approximately 95 (0.95%) and 40 (0.40%) basis points, respectively, through sector allocation. Being overweight the Consumer Staples sector also contributed to the Fund’s returns. An underweight position in Health Care, the best performing sector in the Index and the Fund’s overweight in the Industrials sector, detracted relative value.

High Yield Bond Market Overview

August 31, 2015 (Unaudited)

For the 12-month period ended August 31, 2015, the BofA Merrill Lynch U.S. High Yield Master II Index (“the Index”) returned -3.07%. All of the negative return was due to the troubled Energy and Metals & Mining sectors. The price of West Texas Intermediate Crude Oil fell from approximately $93 per barrel at the beginning of the period to a low of approximately $39 per barrel and finished the period at approximately $49 per barrel. Almost all commodities in the Metals & Mining sector were under pressure for the year due to the slowdown in China. The Energy sector comprises 14% of the Index and returned -20% for the period. The Metals & Mining sector comprises 3.5% of the Index and returned -26% for the period. Excluding these two sectors, the Index gained 0.8% for the period.

For the period under review, high-yield bond market spreads widened from 400 basis points (4.00%) to 575 basis points (5.75%), while the Energy sector spread rose from 400 basis points (4.00%) to 960 basis points (9.60%), and the spread for the Metals & Mining sector rose from 515 basis points (5.15%) to 1,225 basis points (12.25%). Excluding those two sectors, the spread for the Index would have risen from 395 basis points (3.95%) to 490 basis points (4.90%). A spread of 490 basis points (4.90%) is essentially at the long-term median for the high-yield bond market.

An estimated $18 billion of outflows (about 5% of high-yield mutual fund assets) occurred during the period under review.

Even though the U.S. economy has been moving along fairly well, the widening of spreads (excluding Energy and Metals & Mining) was due to the inertia effect of those two troubled sectors on the rest of the market, uncertainties regarding the slowdown in China and emerging markets, and volatility around the U.S. Federal Reserve’s potential interest rate increase.

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. 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 0.86%, 0.94%, 1.11%, 1.33%, and 2.08%, 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.

From a sector allocation perspective, the Fund’s sizable underweight to the Energy sector added value to the Fund’s relative performance. The Energy sector was the worst performing sector during the period as it fell nearly 20%. Additionally, the Fund’s overweight to the Service sector aided positive relative returns.

American Beacon SiM High Yield Opportunities Fund^SM

Performance Overview

August 31, 2015 (Unaudited)

Issue selection within the Fund’s Manufacturing and Service sector holdings added to the Fund’s outperformance. On the other hand, holdings within the Fund’s Finance and Transportation sectors detracted from relative returns.

From a credit quality standpoint, the Fund benefited from strong security selection within the B, CCC and BB-rated credit categories.

From a credit quality allocation perspective, the Fund’s relative weightings within the high yield credit rating categories (BB, B, and CCC) were detrimental during the period. This was slightly offset by a small allocation to A-rated securities held by the Fund.

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 purpose of creating financial leverage. During the period, the Fund experienced modest losses from the use of derivatives.

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.

August 31, 2015 (Unaudited)

Fund Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs including sales charges (loads) on purchased shares and (2) ongoing costs, including management fees, administrative service fees, distribution (12b-1) fees, and other Fund expenses. The examples below are intended to help you understand the ongoing cost (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period in each Class and held for the entire period from March 1, 2015 through August 31, 2015.

Actual Expenses

Hypothetical Example for Comparison Purposes

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

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

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of

American Beacon The London Company Income Equity Fund, American Beacon Zebra Global Equity Fund, American Beacon Zebra Small Cap Equity Fund, and American Beacon SiM High Yield Opportunities Fund:

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of American Beacon The London Company Income Equity Fund, American Beacon Zebra Global Equity Fund, American Beacon Zebra Small Cap Equity Fund and American Beacon SiM High Yield Opportunities Fund (four of the funds constituting the American Beacon Funds) (collectively, the “Funds”), as of August 31, 2015, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of 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, 2015, 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 American Beacon The London Company Income Equity Fund, American Beacon Zebra Global Equity Fund, American Beacon Zebra Small Cap Equity Fund and American Beacon SiM High Yield Opportunities Fund at August 31, 2015, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein in conformity with U.S. generally accepted accounting principles.

1. Organization and Significant Accounting Policies

American Beacon Funds (the “Trust”), 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. As of August 31, 2015, the Trust consists of thirty-one active series, four of which are presented in this filing (collectively, the “Funds” and each individually a “Fund”): the American Beacon The London Company Income Equity Fund, the American Beacon Zebra Global Equity Fund, the American Beacon Zebra Small Cap Equity Fund, and the American Beacon SiM High Yield Opportunities Fund. The remaining twenty-seven active series are reported in separate filings.

The Manager has closed the Zebra Global Equity Fund to new shareholders as of the close of business on August 20, 2015. Existing shareholders as of that date may continue to purchase, redeem, or exchange shares of the Funds on any business day, which is any day the New York Stock Exchange is open for business.

Class Disclosure

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


Class:		Offered to:
Institutional Class		Investors making an initial investment of $250,000
Y Class		Investors making an initial investment of $100,000
Investor Class		Individual investors investing directly or through an intermediary
A Class		General public and investors investing through an intermediary with applicable sales charges, which may include a front-end sales charge and a contingent deferred sales charge (“CDSC”)
C Class		General public and investors investing through an intermediary with applicable sales charges, which may include a CDSC

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.

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. 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. The Funds pay the unaffiliated investment advisors hired to direct investment activities of the Funds. Management fees paid by the Funds during the year ended August 31, 2015 were as follows (in thousands):


Fund	Management Fee Rate			Management Fee		Amounts paid to Investment Advisors		Amounts Paid to Manager
The London Company Income Equity		0.37	%	$	1,902	$	1,644	$	258
Zebra Global Equity		0.39	%		25		22		3
Zebra Small Cap Equity		0.59	%		121		109		12
SiM High Yield Opportunities		0.45	%		3,648		3,239		409

As compensation for services provided by the Manager in connection with securities lending activities conducted by the Zebra Small Cap Equity Fund, the lending Fund pays to the Manager, with respect to cash collateral posted by borrowers, a fee up to 25% of the net monthly interest income (the gross income earned by the investment of cash collateral, less the amount paid to borrowers and related expenses) from such activities and, with respect to loan fees paid by borrowers, a fee up to 25% of such loan fees. This fee is included in Income derived from securities lending and management and investment advisory fees on the Statements of Operations. During the year ended August 31, 2015, securities lending fees paid to the Manager were $1,265 for the Zebra Small Cap Equity Fund.

Administration Agreement

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

Distribution Plans

The Funds, except for the A and C Classes of the Funds, have adopted a “defensive” Distribution Plan (the “Plan”) in accordance with Rule 12b-1 under the Act, pursuant to which no separate fees may be charged to the Funds for distribution purposes. However, the Plan authorizes the management and administrative service fees received by the Manager and the investment advisor hired by the Manager to be used for distribution purposes. Under this Plan, the Funds do not intend to compensate the Manager or any other party, either directly or indirectly, for the distribution of 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 Funds. Under the Distribution Plans, as compensation for distribution assistance, the Manager receives an annual fee of 0.25% of the average daily net assets of the A Classes and 1.00% of the average daily net assets of the C Classes of each Fund. The fee will be payable without regard to whether the amount of the fee is more or less than the actual expenses incurred in a particular month by the Manager for distribution assistance.

Service Plans

Investment in Affiliated Funds

The Funds may invest in the American Beacon Money Market Select Fund (the “MM Select Fund”) and the American Beacon U.S. Government Money Market Select Fund (the “USG Select Fund”) (collectively the “Select Funds”). Cash collateral received by the Funds in connection with securities lending may be invested in the Select Funds. The Funds and the Select Funds have the same investment advisor and therefore, are considered to be affiliated. The Manager serves as investment advisor to the Select Funds and receives from the Select Funds an annualized management fee of 0.09% of the average daily net assets of the Select Funds. During the year ended August 31, 2015, fees earned by the Manager from the Select Funds were as follows:


Fund	Direct Investments in Select Funds		Fees Earned from Securities Lending Collateral Invested in Select Funds		Total
Zebra Small Cap Equity Fund	$	—	$	382	$	382

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, 2015, the Zebra Small Cap Equity Fund borrowed on average $804,185 for 4 days at an average equity rate of 0.74% with interest charges of $66, and the SiM High Yield Opportunities Fund borrowed on average $1,727,508 for 1 day at a rate of 0.77% with interest charges of $36.

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 year ended August 31, 2015, the Manager waived or reimbursed expenses as follows:


Fund	Class	Expense Cap		Reimbursed or (Recovered) Expenses	Expiration of Reimbursed Expenses

Notes to Financial Statements

Of these amounts, $12,350, $4,860, and $13,419 were disclosed as a receivable from the Manager to Zebra Global Equity, Zebra Small Cap Equity, and SiM High Yield Opportunities Funds, respectively and $3,897 was payable from The London Company Income Equity Fund to the Manager at August 31, 2015. 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 2018. The Funds did not record a liability for potential reimbursements, due to the current assessment that a reimbursement is unlikely. The carryover of excess expenses potentially reimbursable to the Manager are as follows:


Fund	Recovered Expenses		Excess Expense Carryover		Expired Expenses		Expiration of Reimbursed Expenses

3. Security Valuation and Fair Value Measurements

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

Investments in open-end mutual funds are valued at the closing net asset value (“NAV”) per share of the mutual fund on the day of valuation.

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 the Fund 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 its portfolio securities, the Fund 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 Fund 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. In addition, the Fund may use fair value pricing for securities primarily traded in non-U.S. markets because most foreign markets close well before the Funds’ pricing time of 4:00 p.m. ET. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, may have occurred in the interim and may materially affect the value of those securities. These securities are fair valued using a pricing service and are categorized as Level 2 in the fair value hierarchy. The pricing service, using methods approved by the Board, considers the correlation of the trading patterns of the foreign security to intraday trading in the U.S. markets, based on indices of domestic securities and other appropriate indicators such as prices of relevant ADRs and futures

American Beacon Funds^SM

Notes to Financial Statements

contracts. 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 -		Quoted prices in active markets for identical securities.

Level 2 -		Prices determined using other significant observable inputs. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and others.

Level 3 -		Prices determined using other significant unobservable inputs. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in pricing an investment, and would be based on the best information available.

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

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

Mortgage-related and asset-backed securities are usually issued as separate tranches, or classes, of securities within each deal. These securities are also normally valued by pricing service providers that use broker dealer quotations or valuation estimates from their internal pricing models. The pricing models for these securities usually consider tranche-level attributes, current market data, estimated cash flows and market-based yield spreads for each tranche, and incorporate 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.

Investments in registered open-end investment management companies will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy.

Level 3 trading assets and trading liabilities, at fair value

The valuation techniques and significant inputs used in determining the fair values of financial instruments classified as Level 3 of the fair value hierarchy are as follows:

Market quotes are considered not readily available in circumstances where there is an absence of current or reliable market-based data (e.g., trade information or broker quotes), including where events occur after the close of the relevant market, but prior to the Exchange close, that materially affect the values of a Fund’s securities or assets. In addition, market quotes are considered not readily available when, due to extraordinary circumstances, the exchanges or markets on which the securities trade, do not open for trading for the entire day and no other market prices are available. The Board has delegated to the Manager the responsibility for monitoring significant events that may materially affect the fair values of a Fund’s securities or assets and for determining whether the value of the applicable securities or assets should be re-evaluated in light of such significant events.

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. During the year ended August 31, 2015, the Zebra Global Equity Fund transferred Foreign Common Stock and Foreign Preferred Stock with a total value of $1,939 from Level 1 to Level 2 as of the end of period in accordance with fair value procedures established by the Board (in thousands).

The following is a reconciliation of Level 3 assets of the SiM High Yield Opportunities Fund, for which significant unobservable inputs were used to determine fair value. Transfers in or out of Level 3 represent the ending value of any security or instrument where a change in the level has occurred from the beginning to the end of the period.

⁽³⁾

The key assumptions used in the discounted cash flow analysis are the future expected payments to be received, timing of the expected cash flows, and the discount rates used to present value the expected cash flows. The valuation estimate will change if one of the key assumptions either increase or decrease, keeping all other assumptions constant. For example, if the expected cash flows increase/decrease, the valuation estimate will increase/decrease. If the discount rates used decrease / increase, the valuation estimate will increase /decrease.

Security Transactions and Investment Income

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

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

Notes to Financial Statements

August 31, 2015

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 the exchange prevailing on the respective dates of such transactions. The effect of changes in foreign currency exchange rates on investments is separately identified from the fluctuations arising from changes in market values of securities held and is reported with all other foreign currency gains and losses in the Funds’ Statements of Operations.

Dividends to Shareholders

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

Commission Recapture

The Funds, except for the SiM High Yield Opportunities Fund, have established brokerage commission recapture arrangements with certain brokers or dealers. If a Fund’s investment advisor chooses to execute a transaction through a participating broker, the broker rebates a portion of the commission back to the Fund. Any collateral benefit received through participation in the commission recapture program is directed exclusively to the Funds. This amount is reported with the net realized gain in the Funds’ Statements of Operations, if applicable.

Allocation of Income, Expenses, Gains, and Losses

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 pro rata based on their respective net assets.

4. Securities and other Investments

Global Depositary Receipts (“GDRs”) and American Depositary Receipts (“ADRs”)

GDRs are in bearer form and traded in both the U.S. and European securities Markets. ADRs are depositary receipts for foreign issuers in registered form traded in U.S. securities markets. Depositary receipts may not be denominated in the same currency as the securities into which they may be converted. Investing in depositary receipts entails substantially the same risks as direct investment in foreign securities. There is generally less publicly available information about foreign companies and there may be less governmental regulation and supervision of foreign stock exchanges, brokers and listed companies. In addition, such companies may use different accounting and financial standards (and certain currencies may become unavailable for transfer from a foreign currency), resulting in the Fund’s possible inability to convert immediately into U.S. currency proceeds realized upon the sale of portfolio securities of the affected foreign companies. In addition, the Fund may invest in unsponsored depositary receipts, the issuers of which are not obligated to disclose material information about the underlying securities to investors in the United States. Ownership of unsponsored depositary receipts may not entitle the Fund to the same benefits and rights as ownership of a sponsored depositary receipt or the underlying security.

Inflation-Indexed Bonds

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

In-Kind Securities

The SiM High Yield Opportunities Fund may invest in payment in-kind securities (“PIKs”). 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 pro rata adjustment from the unrealized appreciation or depreciation on investment to interest receivable in the Statements of Assets and Liabilities.

Restricted Securities

The Funds 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. Reg S securities cannot be sold in the United States without either an effective registration statement filed pursuant to the Securities Act of 1933, or pursuant to an exemption from registration. 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, 2015 are disclosed in the Notes to the Schedules of Investments.

High-Yield Securities

Real Estate Investment Trusts

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

Other Investment Company Securities and Other Exchange Traded Products

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

Master Agreements

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

5. Financial Derivative Instruments

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

Swap Agreements

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

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

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

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 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

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2015

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.

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. 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. On August 31, 2015 there were no credit default swap agreements outstanding.

For the year ended August 31, 2015, the SiM High Yield Opportunities Fund entered into credit default swaps primarily for return enhancement, hedging, and exposing cash to markets.


Credit Default Swap Notional Amounts Outstanding
Fund	Year ended August 31, 2015
SiM High Yield Opportunities	$	6,000

Over-the-Counter Swap Agreements

OTC financial derivative instruments such as forward currency contracts, options contracts, interest rate, and credit default swap agreements derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. These instruments are valued using evaluated prices furnished by a pricing service selected by the Board. In certain cases, when a valuation is not readily available from a pricing service, the Fund’s Manager may provide a valuation pursuant to procedures approved by the Board. Derivative instruments that use valuation techniques and inputs similar to those described above are normally categorized as Level 2 in the fair valuation hierarchy.

Futures Contracts

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

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

For the year ended August 31, 2015, the Funds entered into future contracts primarily for return enhancement, hedging and exposing cash to markets.

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

6. Principal Risks

In the normal course of business the Funds trade financial instruments and enter into financial transactions where risk of potential loss exists. Security values fluctuate (market risk) and may decline due to factors affecting securities markets in general, particular industries represented in the securities markets or conditions specifically related to a particular company. Failure of the other party to a transaction to perform (credit risk), for example by not making principal and interest payments when due, reduces the value of the

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2015

issuer’s debt and could reduce the Funds’ income. Similar to credit risk, the Funds may be exposed to counterparty risk, or the risk that an institution or other entity with which the Funds have unsettled or open transactions will fail to make required payments or otherwise comply with the terms of the instrument, transaction or contract. The potential loss could exceed the value of the financial assets recorded in the financial statements. Some of the Funds’ investments may be illiquid and the Funds may not be able to vary the portfolio investments in response to changes in economic and other conditions. If a Fund is required to liquidate all or a portion of its investments quickly, the Fund may realize significantly less than the value at which it previously recorded those investments.

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

Market Risks

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

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

Credit and Counterparty Risks

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

American Beacon Funds^SM

Notes to Financial Statements

August 31, 2015

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

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

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

Offsetting Assets and Liabilities

The Funds are parties to enforceable master netting agreements between brokers and counterparties, which provide for the right to offset under certain circumstances. The Funds employ multiple money managers and counterparties and have elected not to offset qualifying financial and derivative instruments on the Statements of Assets and Liabilities, as such all financial and derivative instruments are presented on a gross basis. The impacts of netting arrangements that provide the right to offset are detailed below. The net amount represents the net receivable or payable that would be due from or to the counterparty in the event of default. Exposure from borrowings and other financing agreements such as repurchase agreements can only be netted across transactions governed by the same Master Agreement with the same legal entity. All amounts reported below represent the balance as of August 31, 2015 (in thousands).

7. Federal Income and Excise Taxes

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

The Funds do not have any unrecognized tax benefits in the accompanying financial statements. The tax years for the periods ended August 31, 2012, 2013, 2014 and 2015 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.

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.

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.

Notes to Financial Statements

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, swap income, reclassifications of income from real estate investment securities, publicly traded partnerships, royalty trusts, and dividends that have been reclassified as of August 31, 2015 (in thousands):

Under the Regulated Investment Company Modernization Act of 2010 (the “RIC MOD”), net capital losses recognized by Funds in taxable years beginning after December 22, 2010 are carried forward indefinitely and retain their character as short-term and/or long-term losses.

As of August 31, 2015, The London Company Income Equity Fund has $1,891 of post RIC MOD short-term capital loss carryforward (in thousands).

The Funds are permitted for tax purposes to defer into their next fiscal year qualified late year losses. Qualified late year capital losses are any capital losses incurred after October 31 through the Funds’ fiscal year end, August 31, 2015. Qualified late year ordinary losses are specified losses generally incurred after October 31 and ordinary losses incurred after December 31 through the end of the Funds’ fiscal year, August 31, 2015. For the period ended August 31, 2015, SiM High Yield Opportunities Fund deferred $6,908 late year specified ordinary loss (in thousands).

9. Securities Lending

The Zebra Small Cap Equity Fund may lend its securities to qualified financial institutions, such as certain broker-dealers, to earn additional income. The borrowers are required to secure their loans continuously with collateral in an amount at least equal to the fair value of the securities loaned, initially in an amount at least equal to 102% of the fair value of domestic securities loaned and 105% of the fair value of international securities loaned. Collateral is monitored and marked to market daily. Daily mark to market amounts are required to be paid to the borrower or received from the borrower by the end of the following business day. This one day settlement for mark to market amounts may result in the collateral being temporarily less than the value of the securities on loan or temporarily more than the required minimum collateral.

To the extent that a loan is collateralized by cash, such cash collateral shall be invested by the securities lending agent (the “Agent”) in money market mutual funds, and other short-term investments, provided the investments meet certain quality and diversification requirements. Securities purchased with cash collateral proceeds are listed in the Fund’s Schedule of Investments and the collateral is shown on the Statements of Assets and Liabilities as a payable.

Securities lending income is generated from the demand premium (if any) paid by the borrower to borrow a specific security and from the return on investment of cash collateral, reduced by negotiated rebate fees paid to the borrower and transaction costs. To the extent that a loan is secured by non-cash collateral, securities lending income is generated as a demand premium reduced by transaction costs. The Fund, the Agent, and the Manager retained 80%, 10%, and 10%, respectively, of the income generated from securities lending.

While securities are on loan, the Fund continues to receive certain income associated with that security and any gain or loss in the market price that may occur during the term of the loan. In the case of domestic equities, the value of any dividend is received in the form of a substitute payment approximately equal to the dividend. In the case of foreign securities, a negotiated amount is received that is less than the actual dividend, but higher than the dividend amount minus the foreign tax that the Fund would be subject to on the dividend.

Securities lending transactions pose certain risks to the Fund, including that the borrower may not provide additional collateral when required or return the securities when due, that the value of the short-term investments will be less than the amount of cash collateral required to be returned to the borrower, that non-cash collateral may be subject to legal constraints in the event of a borrower bankruptcy, and that the cash collateral investments could become illiquid and unable to be used to return collateral to the borrower. The Fund could also experience delays and costs in gaining access to the collateral. The Fund bears the risk of any deficiency in the amount of the cash collateral available for return to the borrower and any action which impairs its ability to liquidate non-cash collateral to satisfy a borrower default.

At August 31, 2015, the value of outstanding securities on loan and the value of collateral was as follows (in thousands):


Fair Value of Securities on Loan		Non-Cash Collateral		Cash Collateral Posted by Borrower
$	144,000	$	—	$	147,000

Cash collateral is listed in the Funds’ Schedules of Investments and is shown on Statements of Assets and Liabilities. Income earned on these investments is included in Income derived from securities lending in the Statements of Operations.

Non-cash collateral received by the Funds may not be sold or re-pledged except to satisfy a borrower default. Therefore, non-cash collateral is not included on the Funds’ Schedules of Investments or Statements of Assets and Liabilities.

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

At an in-person meeting held on November 12, 2014, telephonic meetings held on November 26, 2014 and December 6, 2014 and an in-person meeting held on December 10, 2014 (collectively, the “Board Meetings”), the Board of Trustees (“Board”) considered the approval of: (1) a new Management Agreement (“New Management Agreement”) among American Beacon Advisors, Inc. (“Manager”) and the American Beacon Funds (“Trust”) on behalf of the American Beacon The London Company Income Equity Fund (“London Company Fund”), the American Beacon SiM High Yield Opportunities Fund (“SiM Fund”), the American Beacon Zebra Global Equity Fund (“Zebra Global Fund”) and the American Beacon Zebra Small Cap Equity Fund (“Zebra Small Cap Fund” and, together with the Zebra Global Fund, the “Zebra Funds”) (collectively, the “Funds”); (2) a new Investment Advisory Agreement among the Manager, The London Company of Virginia, LLC (“TLC”) and the Trust, on behalf of the London Company Fund; (3) a new Investment Advisory Agreement among the Manager, Strategic Income Management, LLC (“SiM”) and the Trust, on behalf of the SiM Fund; and (4) a new Investment Advisory Agreement among the Manager, Zebra Capital Management, LLC (“Zebra”) and the Trust, on behalf of the Zebra Funds (collectively, the “New Advisory Agreements”). Collectively, TLC, SiM and Zebra are hereinafter referred to as the “Sub-Advisors.”

The Board meetings were held for the Trustees to consider the New Management Agreement and New Advisory Agreements (“New Agreements”) because, on November 20, 2014, Lighthouse Holdings Parent, Inc. (“LPHI”), the indirect parent company of the Manager, entered into an Agreement and Plan of Merger pursuant to which LHPI agreed to be acquired by Kelso Investment Associates VIII, L.P., KEP VI, LLC and Estancia Capital Partners L.P., investment funds affiliated with Kelso & Company, L.P. (“Kelso”) and Estancia Capital Management, LLC (“Estancia”) (collectively, the “Purchasers”), which are private equity firms (the “Transaction”). As required by the Investment Company Act of 1940, as amended (“1940 Act”), the current Management Agreement (“Current Management Agreement”) among the Manager and the Trust on behalf of the London Company Fund, SiM Fund and Zebra Funds and the current Investment Advisory Agreements (“Current Advisory Agreements”) among the Manager, TLC and the Trust, on behalf of the London Company Fund, the Manager, SiM and the Trust, on behalf of the SiM Fund, and the Manager, Zebra and the Trust, on behalf of the Zebra Funds, provide for their automatic termination in the event of an assignment. As a result, the Current Management Agreement and each Current Advisory Agreement (“Current Agreements”) would terminate upon the closing of the Transaction. (The Transaction closed on April 30, 2015).

The Board focused on the effect that the Transaction would have on the Manager and the Funds. Additionally, the Board considered that it had requested and evaluated the information relevant to the renewal of the Current Management Agreement and Current Advisory Agreements at in-person meetings held in May and June 2014. The Manager represented to the Board that there had been no material changes or developments relating to the Manager or any of the Sub-Advisors since the May and June 2014 meetings, other than the changes or developments subsequently reported to the Board or discussed in the due diligence materials submitted to the Trustees in connection with the Transaction. In light of the proximity of the Board’s consideration of the renewal or approval of the Current Agreements, and the Board’s ongoing due diligence review in connection with the Transaction, the Board determined that it was not necessary to repeat certain aspects of the review conducted in connection with the approvals in the past year.

In determining whether to approve the New Agreements, the Trustees considered the best interests of each Fund separately. The Board considered each Fund’s investment management and sub-advisory relationships separately. In each instance, the Board considered its review of the Current Agreements in May and June 2014, and the information received in November and December 2014 with respect to, 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 Sub-Advisor for a Fund; (3) the costs incurred by the Manager in rendering services to the Funds and its resulting profits or losses; (4) comparisons of services and fee rates with contracts entered into by the Manager or a Sub-Advisor or their affiliates with other clients (such as pension funds and other institutional clients); (5) the extent to which economies of scale have been taken into account in setting each fee rate schedule; (6) whether fee rate levels reflect these economies of scale for the benefit of Fund investors; and (7) any other benefits derived or anticipated to be derived by the Manager or a Sub-Advisor from their relationship with a Fund. The Trustees posed questions to various management personnel of the Manager and the Purchasers regarding certain key aspects of the materials submitted in support of the approval of the New Agreements.

Nature, Extent and Quality of the Services Provided. With respect to the approval of the New Agreements, the Board considered that the New Agreements provide for the Manager and each Sub-Advisor to provide the same services to each Fund on substantially the same terms as the Current Agreements. The Board considered representations by the Manager and/or Purchasers that the Transaction will not result in any changes to the manner in which each Fund’s assets are managed. The Board also considered representations by the Manager and/or the Purchasers that the Transaction will not result in any adverse impact or changes to: the personnel involved in the management of the Funds; the Manager’s disciplined investment approach and goal to provide consistent above average long-term performance at a lower than average cost; the Manager’s continuing efforts to enhance distribution of the Funds’ shares and add new series to the Trust and share classes to the Funds’ product line; the adequacy of the Manager’s financial condition; the Manager’s day-to-day operations; the Manager’s compliance activities or the resources available to the Trust’s Chief Compliance Officer; or the Funds’ service providers or Sub-Advisors. The Board also considered the Manager’s representation that there had been no material changes or developments regarding the Manager or the Sub-Advisors since the Board’s consideration of the Current Agreements in May and June 2014 that had not previously been reported to the Board. The Board also considered information regarding the post-closing capitalization of the Purchasers and the Purchasers’ long-term business goals with regard to the Manager and the Manager’s activities with respect to the Trust, which are consistent with the Manager’s current goals. 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 the Sub-Advisors were appropriate for each Fund and, thus, determined to approve the New Agreements for each Fund.

Investment Performance. The Board considered its review of the comparative information regarding each Fund’s investment performance relative to its benchmark index(es) and peer group in connection with the renewal of the Current Agreements. The Board also considered the performance reports and discussions with management at Board and Committee meetings since June 2014. The Manager also noted that it generally was satisfied with the performance of the Sub-Advisors.

Costs of the Services to be Provided to the Funds and the Projected Profits to be Realized by the Manager from its Relationship with the Funds. In analyzing the cost of services and profitability of the Manager by Fund, the Board considered that the Transaction would result in no changes to the fees charged to the Funds or the Manager’s fee waivers currently in place with respect to each Fund. Additionally, the Board noted that there had been no material changes in this regard since its consideration of the Current Agreements in May and June 2014. Based on the foregoing information and the Board’s considerations in connection with the renewal of the Current Agreements in May and June 2014, the Board concluded that the profitability levels were reasonable in light of the services performed by the Manager. The Board did not consider the costs of the services to be provided and profits to be realized by each Sub-Advisor from its relationship with its respective Fund, noting instead the substantially arm’s-length nature of the relationship between the Manager and each Sub-Advisor with respect to the negotiation of the advisory fee rate on behalf of the Funds.

Economies of Scale and Whether Fee Levels Reflect Economies of Scale. In considering the reasonableness of the management fees, the Board considered that the Funds would pay the same fee rates to the Manager under the New Management Agreement as the Funds currently pay under the Current Management Agreement. The Board also considered that each Fund would pay the same investment advisory fee rate to its Sub-Advisor under the New Advisory Agreement as the Fund pays under its Current Advisory Agreement. Based on the foregoing information and the Board’s considerations in connection with the renewal of the Current Agreements in May and June 2014, the Board concluded that the Manager’s fee schedule for each Fund, TLC’s fee schedule for the London Company Fund, SiM’s fee schedule for the SiM Fund, and Zebra’s fee schedules for the Zebra Funds, provide for a reasonable sharing of benefits from any economies of scale with each Fund.

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

Benefits Derived by the Manager from Relationship With the Funds. The Board considered that the “fall-out” or ancillary benefits that accrue to the Manager and/or the Sub-Advisors as a result of the advisory relationships with the Funds would not change as a result of the Transaction. Based on the foregoing information and the Board’s considerations in connection with the renewal of the Current Agreements in May and June 2014, the Board concluded that the potential benefits accruing to the Manager and the Sub-Advisors under the New Management Agreement and the New Advisory Agreements by virtue of the Manager’s relationship with the Funds, TLC’s relationship with the London Company Fund, SiM’s relationship with the SiM Fund, and Zebra’s relationship with the Zebra Funds appear to be fair and reasonable.

Board’s Conclusion. Based on the various considerations described above, the Board, including a majority of Trustees who are not “interested persons” of the Fund, the Manager, TLC, SiM or Zebra, as that term is defined in the 1940 Act, concluded that the management and investment advisory fee rates to be paid by the London Company Fund, the SiM Fund and the Zebra Funds are fair and reasonable and that the approval of the New Agreements is in the best interests of the London Company Fund, the SiM Fund and the Zebra Funds, and approved the New Agreements.
