President’s Message

Dear Shareholders,   In the weeks ahead of the U.S. presidential election on November 8, 2016, uncertainty about the outcome caused many investors to stay on the sidelines. Some investors questioned whether the election’s result would have negative consequences for their portfolios, although elections have rarely had a lasting effect on the market.   Following the election, the markets responded positively to aspects of the incoming administration’s proposed plans for economic growth; i.e., repatriating jobs from overseas, relaxing regulations, lowering taxes and increasing infrastructure spending. From Election Day 2016 to Inauguration Day 2017, the S&P 500 Index – a broad measure of the performance of large U.S. companies – climbed approximately 6%. From Inauguration Day to February 28, it gained approximately 4%.

Economists anticipated the Federal Reserve would increase the federal funds rate – perhaps as early as mid-March. The Federal Open Market Committee’s confidence in the improving U.S. economy was exhibited in December 2016 when short-term interest rates increased by 0.25% to a range of 0.50% to 0.75%. It was the second increase since 2008; the first increase occurred in December 2015.

For the six-month period that ended February 28, 2017, the Dow Jones Industrial Average, which follows the performance of 30 significant stocks trading on the New York Stock Exchange and The NASDAQ Stock Market, gained 14.51%; and the S&P 500 Index, a domestic equity bellwether, grew 10.01%. In contrast, during the same period, the Bloomberg Barclays U.S. Aggregate Index, a benchmark for domestic corporate and government bonds, returned -2.19%; the Bank of America Merrill Lynch U.S. High Yield Master II Index, which represents domestic, below-investment-grade corporate debt, returned 5.54%; and the Credit Suisse Leveraged Loan Index, which represents the U.S.denominated, leveraged-loan market, returned 4.30%.

For the 6 months ended February 28, 2017:

• American Beacon SiM High Yield Opportunities Fund (Investor Class) returned 5.55%.

• American Beacon Sound Point Floating Rate Income Fund (Investor Class) returned 3.86%.

At American Beacon Advisors, we are proud to offer a broad range of global equity and fixed-income funds sub-advised by experienced asset managers who employ distinctive investment processes to manage assets through a variety of economic and market conditions. Together, we work diligently to help our shareholders meet their long-term financial goals.

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

2. A portion of the fees charged to the Institutional Class of the Fund has been waived since inception. Performance prior to waiving fees was lower than actual returns shown. A portion of the fees charged to the Investor Class of the Fund was waived in 2011 and 2012 and partially recovered in 2013 and 2016. Performance prior to waiving fees was lower than actual returns shown in 2011 and 2012. A portion of the fees charged to the A, and C Classes of the Fund was waived from 2011 through 2014 and partially recovered in 2015 and 2016. Performance prior to waiving fees was lower than the actual returns shown from 2011 through 2014. A portion of the fees charged to the Y Class of the Fund was waived from 2011 through 2013, partially recovered in 2015 and waived in 2016. Performance prior to waving fees was lower than actual returns shown from 2011 through 2013 and in 2016.

3. The BofA Merrill Lynch U.S. 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.

4. The Total Annual Fund Operating Expense ratios set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A, and C Class shares was 0.92%, 0.92%, 1.18%, 1.24%, and 1.98%, 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 selection perspective, the Fund’s Energy, Finance, and Consumer sector holdings added to the Fund’s outperformance. On the other hand, issue selection within the Fund’s Service and Manufacturing sectors detracted from relative returns.

From a sector allocation standpoint, overweighting the Consumer sector detracted from Fund performance. Conversely, an overweight to the Energy sector contributed positively to relative returns.

From a credit quality selection perspective, the Fund’s relative performance was hindered by poor security selection in the CCC-rated credit category. This was partially offset by positive issue selection within the below C-rated and BB-rated credit categories, which were additive to Fund performance.

From a credit quality allocation standpoint, the Fund’s underweight to the BB-rated and overweight to the CCC-rated credit categories contributed positively to the Fund’s relative performance. In contrast, null weighting the CC-rated credit category detracted from the Fund’s returns.

Performance Overview

February 28, 2017 (Unaudited)

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 gains 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.

6. The Total Annual Fund Operating Expense ratios set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A, C, and SP Class shares was 1.28%, 1.44%, 1.33%, 1.69%, 2.57%, and 1.51%, 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 underweight position in the commodity-sensitive sectors, primarily Energy and Metals/Materials, was the main source of underperformance as those sectors significantly outperformed the broader market. Stabilization in commodity prices during 2016 allowed the sectors to recover following a two-year correction, and an improved economic outlook gave investors confidence going forward. The Fund has been underweight these sectors since late-2014 when commodity prices first started deteriorating. The Fund’s significant outperformance in 2014 and 2015 was due to that positioning. In 2016, however, when the commodity markets turned, the Fund began to underperform.

The sub-advisor’s strategy seeks to avoid highly-leveraged, cyclical sectors (such as energy, mining, retail, and lodging) as they inevitably experience volatile corrections. Likewise, the strategy also avoids overly-hyped sectors (such as that which Health Care recently experienced) as market valuations became unattractive.

Also during the six-month period ended February 28, 2017, the Fund’s total assets increased from $110 million to $543 million as investors were encouraged by the floating-rate nature of the Fund and its incremental

yield. During this time, a significant amount of assets was invested in new holdings, and a portion was held in cash to help provide liquidity, if needed. These factors detracted slightly from returns as nearly all sectors of the bank loan market were positive during the period.

Expense Examples

February 28, 2017 (Unaudited)

Fund Expense Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption fees if applicable, and (2) ongoing costs, including management fees, administrative service fees, distribution (12b-1) fees, and other Fund expenses. The Examples are intended to help you understand the ongoing costs (in dollars) of investing in the Funds 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 September 1, 2016 through February 28, 2017.

Actual Expenses

The “Actual” lines of the tables 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 = $8.60), then multiply the result by the “Expenses Paid During Period” for the applicable Fund to estimate the expenses you paid on your account during this period. Shareholders of the Institutional and Investor Classes that invest in the Funds through an IRA or Roth IRA may be subject to a custodial IRA fee of $15 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $15 higher.

Hypothetical Example for Comparison Purposes

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

Notes to Financial Statements

February 28, 2017 (Unaudited)

1. Organization and Significant Accounting Policies

American Beacon Funds (the “Trust”), is organized as a Massachusetts business trust. The Funds, each a series within the Trust, are registered under the Investment Company Act of 1940, as amended (the “Act”), as non-diversified, open-end management investment companies. As of February 28, 2017, the Trust consists of twenty-seven active series, two of which is presented in this filing (collectively, the “Funds” and each individually a “Fund”): American Beacon SiM High Yield Opportunities Fund (“SiM HYO Fund”) and the American Beacon Sound Point Floating Rate Income Fund (“Sound Point Fund”). The remaining twenty-five active series are reported in separate filings.

American Beacon Advisors, Inc. (the “Manager”) is a wholly-owned subsidiary of Resolute Investment Managers, Inc., which is indirectly owned by investment funds affiliated with Kelso & Company, L.P. and Estancia Capital Management, LLC, and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services to the Trust and other investors.

New Accounting Pronouncements

In October 2016, the SEC adopted amendments to rules under the Investment Company Act of 1940 (“final rules”) intended to modernize the reporting and disclosure of information by registered investment companies. The final rules amend Regulation S-X and require funds to provide standardized, enhanced derivative disclosure in fund financial statements in a format designed for individual investors. The amendments to Regulation S-X also update the disclosures for other investments and investments in, and advances to affiliates and amend the rules regarding the general form and content of fund financial statements. The compliance date for the amendments to Regulation S-X is August 1, 2017. Management is currently evaluating the amendments and the impact, if any, on the fund’s financial statements.

Class Disclosure

The Funds have multiple classes of shares designed to meet the needs of different groups of investors; however, not all of the Funds offer all classes. The following table sets forth the differences amongst the classes:

		Minimum Initial
Class	Eligible Investors	Investments
Institutional	Large institutional investors - sold directly or through intermediary channels.	$	250,000
Y Class	Large institutional retirement plan investors - sold directly or through intermediary channels.	$	100,000
Investor	All investors using intermediary organizations such as broker-dealers or retirement plan sponsors - sold directly through intermediary channels.	$	2,500
A Class	All investors who invest through intermediary organizations, such as broker-dealers or third party administrator. Retail investors who invest directly through a financial intermediary such as a broker, bank, or registered investment advisor, which may include a front-end sales charge and a contingent deferred sales charge (“CDSC”).	$	2,500
C Class	Retail investors who invest directly through a financial intermediary such as a broker or employee directed benefit plans with applicable sales charges, which may include CDSC.	$	1,000
SP	Retail investors who invest directly through a financial intermediary such as a broker, or through employee directed benefit plans and were formerly shareholders of the Investor Class Shares of the Sound Point Floating Rate Fund prior to its reorganization.	$	1,000

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

22

Notes to Financial Statements

February 28, 2017 (Unaudited)

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.

The following is a summary of significant accounting policies, consistently followed by the Funds in the preparation of the financial statements. The Funds are investment companies, and accordingly, follow the investment company accounting and reporting guidance of the Financial Accounting Standards Board Accounting Standard Codification Topic 946, Financial Services - Investment Companies, which is part of U.S. Generally Accepted Accounting Principles (“U.S. GAAP”).

Security Transactions and Investment Income

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

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

Currency Translation

All assets and liabilities initially expressed in foreign currency values are converted into U.S. dollar values at the mean of the bid and ask prices of such currencies against U.S. dollars as last quoted by a recognized dealer. Income, expenses, and purchases and sales of investments are translated into U.S. dollars at the rate of 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 generally will be declared daily and paid monthly. Distributions, if any, of net realized capital gains are generally paid at least annually and recorded on the ex-dividend date. Dividends to shareholders are determined in accordance with federal income tax regulations, which may differ in amount and character from net investment income and realized gains recognized for purposes of U.S. GAAP.

Commission Recapture

The Funds have established brokerage commission recapture arrangements with certain brokers or dealers. If a Fund’s investment advisor chooses to execute a transaction through a participating broker, the broker rebates a portion of the commission back to the Fund. Any collateral benefit received through participation in the commission recapture program is directed exclusively to the Funds. This amount is reported with the net realized gain in the Funds’ Statements of Operations, if applicable. For the six months ended February 28, 2017, the Funds did not have commission recapture income.

23

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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.

Redemption Fees

All classes of the SiM HYO Fund impose 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. Effective December 29, 2016, the redemption fee was terminated by the Trust’s Board of Trustees (the “Board”).

Other

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liabilities 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.

2. Transactions with Affiliates

Management Agreement

The Funds and the Manager are parties to a Management Agreement that obligates the Manager to provide investment advisory, fund management, and administrative services to the Funds. As compensation for performing the duties under the Management Agreement, the Manager receives from the Funds an annualized fee at the following annual rates as a percentage of average daily net assets: 0.35% of the first $5 billion, 0.325% of the next $5 billion, 0.30% of the next $10 billion, and 0.275% over $20 billion. The Funds pay the unaffiliated investment advisors hired to direct investment activities of the Funds an annualized investment advisory fee based on a percentage of the Funds’ average daily assets. Management fees paid by the Funds during the six months ended February 28, 2017 were as follows:

						Amounts paid
	Management Fee			Management		to Investment		Amounts Paid
Fund	Rate			Fee		Advisors		to Manager
SiM HYO		0.75	%	$	4,188,632	$	2,166,855	$	2,021,777
Sound Point		0.70	%		795,995		397,998		397,997

Distribution Plans

The Funds, except for the A, C, and SP Classes, have adopted a “defensive” Distribution Plan (the “Plan”) in accordance with Rule 12b-1 under the Act, pursuant to which no separate fees will be charged to the Funds for distribution purposes. However, the Plan authorizes the management fees received by the Manager and the investment advisors hired by the Manager to be used for distribution purposes. Under this Plan, the Funds do not

24

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

intend to separately 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, C, and SP Classes of the Funds. Under the Distribution Plans, as compensation for distribution assistance, the Manager receives an annualized fee of 0.25% of the average daily net assets of the A, and SP Classes and 1.00% of the average daily net assets of the C Class. 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 an annualized fee up to 0.10% of the average daily net assets of the Y Class, up to 0.25% of the average daily net assets of the A and C Classes, and up to 0.375% of the average daily net assets of the Investor Class of the Funds.

Sub-Transfer Agent Fees

The Manager has entered into agreements, which include servicing agreements, with financial intermediaries that provide recordkeeping, processing, shareholder communications and other services to customers of the intermediaries that hold positions in the Institutional Class of the Funds and has agreed to compensate the intermediaries for providing these services. Intermediary’s transact with the Funds primarily through the use of omnibus accounts on behalf of their customers who hold positions in the Fund(s). Certain services would have been provided by the Funds’ transfer agent and other service providers if the shareholders’ accounts were maintained directly by the Funds’ transfer agent. Accordingly, the Funds, pursuant to the Board approval, have agreed to reimburse the Manager for all or a portion of the servicing fees paid to these intermediary’s for the Institutional Class. The reimbursement amounts (sub-transfer agent fees) paid to the Manager are subject to a fee limit of up to 0.10% of an intermediary’s average net assets in the Institutional Class on an annual basis. For the period ended February 28, 2017, the sub-transfer agent fees, as included in “Transfer agent fees” on the Statements of Operations, were as follows:

Fund	Sub-Transfer Agent Fees
SiM HYO	$	119,995
Sound Point		15,056

As of February 28, 2017, the Funds owed the Manager the following reimbursements of sub-transfer agent fees, as included in “Transfer agent fees payable” on the Statements of Assets and Liabilities:

	Reimbursement of
Fund	Sub-Transfer Agent Fees
SiM HYO	$	15,958
Sound Point		1,540

Investment in Affiliated Funds

The Funds may invest in the American Beacon U.S. Government Money Market Select Fund (the “USG Select Fund”). The Funds and the USG Select Fund have the same investment advisor and therefore, are considered to be affiliated. The Manager serves as the investment advisor to the USG Select Fund and receives management fees totaling 0.10% of the average daily net assets of the USG Select Fund. During the period ended February 28, 2017, the Manager earned fees on the Funds’ direct investments in the USG Select Fund as shown below:

25

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

Fund	Direct Investments in USG Select Funds
SiM HYO	$	7,816
Sound Point		33,287

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 period ended February 28, 2017, the SiM High Yield Opportunities Fund borrowed on average $3,088,289 for 4 days at an average rate of 1.01% with interest charges of $340. This amount is recorded within “Other expenses” on the accompanying Statements of Operations.

Expense Reimbursement Plan

The Manager contractually agreed to reimburse the classes of the Funds to the extent that total annual fund operating expenses exceeded the Funds’ expense cap. For the six months ended February 28, 2017, the Manager waived or reimbursed expenses as follows:

Fund	Class		Expense Cap 9/1/2016 to 2/28/2017			Reimbursed Expenses		Expiration
SiM HYO		Institutional		0.84	%	$	—		2020
Sound Point		Institutional		0.84	%		7,479		2020

Of these amounts, $6,667 was disclosed as a payable to the Manager on the Statements of Assets and Liabilities at February 28, 2017 for the Sound Point Fund. 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’ 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 2020. 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		Expiration of Reimbursed Expenses
SiM HYO	$	—	$	23,730		2017
SiM HYO		—		60,056		2018
SiM HYO		—		175,131		2019
Sound Point		—		236,521		2019

Sales Commissions

The Funds’ distributor, Foreside Fund Services, LLC (“Foreside”) may receive a portion of A Class sales charges from broker dealers and it may be used to offset distribution related expenses. For the six months ended February 28, 2017, Foreside collected $16,202 and $33,336 in sales commissions from the sale of A Class shares for SiM HYO and Sound Point Funds, respectively.

A 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 six months ended February, 28, 2017, fees of $650 were collected for the

26

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

Class A Shares of the SIM HYO 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 period ended February 28, 2017, CDSC fees of $4,105 and $5,437 were collected from the Class C Shares of the SiM HYO and Sound Point Funds, respectively.

Trustee Fees and Expenses

As compensation for their service to the Trust and the American Beacon Select Funds Trust, each Trustee receives an annual retainer of $120,000, plus $5,000 for each Board of Trustee meeting attended in person or via teleconference, $2,500 for attendance by Committee members at meetings of the Audit Committee and the Investment Committee, and $1,500 for attendance by Committee members at meetings of the Nominating and Governance Committee, plus reimbursement of reasonable expenses incurred in attending Board meetings, Committee meetings, and relevant educational seminars. The Trustees also may be compensated for attendance at special Board and/or Committee meetings from time to time. The Board Chairman receives an additional annual retainer of $50,000 as well as a single $5,000 fee each quarter for his attendance at the Committee meetings. The chairpersons of the Audit Committee and the Investment Committee each receive an additional annual retainer of $25,000 and the Chairman of the Nominating and Governance Committee receives an additional annual retainer of $10,000. These expenses are allocated on a prorated basis to each Fund of the Trust according to its respective net assets.

3. Security Valuation and Fair Value Measurements

Investments are valued at the close of the New York Stock Exchange (the “Exchange”), normally 4:00 p.m. Eastern Time, 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 are normally valued on the basis of prices provided by an independent pricing service and may take into account appropriate factors such as trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The prices of debt securities may be determined using quotes obtained from brokers.

Investments in open-end mutual funds are valued at the closing 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.

Futures contracts are valued based upon their quoted daily settlement prices. Upon entering into a futures contract, the Funds are 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 Funds. 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.

27

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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 its 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. In addition, the Funds 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. Eastern Time. 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 American Depository Receipts (“ADRs”) and futures 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 may 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.

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 Funds’ Board.

Valuation Inputs

Various inputs may be used to determine the fair 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. Fixed-income securities are considered Level 2 as they are valued using observable inputs.
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.

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

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

Mortgage-related and asset-backed securities are usually issued as separate tranches, or classes, of securities within each deal. These securities are also normally valued by pricing service providers that use broker

28

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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.

Common stocks, ETFs and financial derivative instruments, such as futures contracts, 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.

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.

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. 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, has been included below.

The Funds’ investments are summarized by level based on the inputs used to determine their values. As of February 28, 2017, the investments were classified as described below:

SiM HYO Fund (1)	Level 1		Level 2		Level 3		Total

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 six months ended February 28, 2017, there were no transfers between levels for the Sound Point Fund.

The following is a reconciliation of Level 3 assets of the SiM HYO 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.

	Domestic Obligations			Foreign Convertible Obligations			Total

⁽¹⁾ Change in unrealized appreciation (depreciation) attributable to Level 3 securities held at period end. This balance is included in the change in unrealized appreciation (depreciation) on the Statements of Operations.

The following is a summary of significant unobservable inputs used in the fair valuation of the asset categorized within Level 3 of the fair value hierarchy:

Security Type	Fair Value At 2/28/2017		Valuation Technique	Unobservable Inputs	Input Assumptions	Fair Value at 2/28/2017 per share
Foreign Convertible Obligations	$	824,605	Expected Debt for Equity Swap in Recapitalization	Projected EBITDA, EBITDA Multiple, discount rate for uncertainty	Projected EBITDA, Valuation Multiple, Liquidity discount (2)	5.54 EUR/ 5.87 USD
Corporate Obligations	$	4,375,000	Comparison of Yield to similar Debt Instruments	Comparative yields, Liquidity Discount	Comparative yields, Liquidity Discount (3)	87.50 USD

⁽²⁾  These obligations are placeholders for a package of notes received in the bankruptcy restructuring. The key assumptions used in the valuation include projected EBITDA of 70 million Euro, 8x EBITDA multiple based on comparable companies, and a 15% liquidity discount. The valuation estimate will change if the debt for equity swap does not occur or if any of the assumptions change.

⁽³⁾ These obligations are secured by collateral. Valuation may change if the yields of comparative bonds change, or the level of collateral coverage declines, or if the market imputes a higher liquidity discount to these bonds than presently incorporated into the fair value.

4. Securities and Other Investments

American Depositary Receipts (“ADRs”)

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 a Funds’ possible inability to convert immediately into U.S. currency proceeds realized upon the sale of portfolio securities of the affected foreign companies. In addition, a Fund may invest in unsponsored depositary receipts, the issuers of which are not obligated to disclose material

31

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

information about the underlying securities to investors in the United States. Ownership of unsponsored depositary receipts may not entitle a Fund to the same benefits and rights as ownership of a sponsored depositary receipt or the underlying security.

Bank Loans and Senior Loans

Loans are typically administered by a bank, insurance company, finance company or other financial institution (the “agent”) for a lending syndicate of financial institutions. In a typical loan, the agent administers the terms of the loan agreement and is responsible for the collection of principal and interest and fee payments from the borrower and the apportionment of these payments to all lenders that are parties to the loan agreement. In addition, an institution (which may be the agent) may hold collateral on behalf of the lenders. Typically, under loan agreements, the agent is given broad authority in monitoring the borrower’s performance and is obligated to use the same care it would use in the management of its own property. In asserting rights against a borrower, a Fund normally will be dependent on the willingness of the lead bank to assert these rights, or upon a vote of all the lenders to authorize the action. If an agent becomes insolvent, or has a receiver, conservator, or similar official appointed for it by the appropriate regulatory authority, or becomes a debtor in a bankruptcy proceeding, the agent’s appointment may be terminated and a successor agent would be appointed. If an appropriate regulator or court determines that assets held by the agent for the benefit of purchasers of loans are subject to the claims of the agent’s general or secured creditors, a Fund might incur certain costs and delays in realizing payment on a loan or suffer a loss of principal and/or interest. A Fund may be subject to similar risks when it buys a participation interest or an assignment from an intermediary.

Bank loans can be fixed and floating rate loans arranged through private negotiations between a company or a non-U.S. government and one or more financial institutions (lenders). The Funds may invest in senior loans, which are floating rate loans that hold a senior position in the capital structure of U.S. and foreign corporations, partnerships or other business entities that, under normal circumstances, allow them to have priority of claim ahead of other obligations of a borrower in the event of liquidation. Bank loans and senior loans may be collateralized or uncollateralized. They pay interest at rates that float above, or are adjusted periodically based on, a benchmark that reflects current interest rates. The Funds may invest in such loans in the form of participations in loans and assignments of all or a portion of loans from third parties. In connection with purchasing participations in such instruments, the Funds generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not benefit directly from any collateral supporting the loan in which it has purchased the participation. When the Fund purchases assignments from lenders, the Funds will acquire direct rights against the borrower on the loan.

Common Stock

Common stock generally takes the form of shares in a corporation which represent an ownership interest. It ranks below preferred stock and debt securities in claims for dividends and for assets of the company in a liquidation or bankruptcy. The value of a company’s common stock may fall as a result of factors directly relating to that company, such as decisions made by its management or decreased demand for the company’s products or services. A stock’s value may also decline because of factors affecting not just the company, but also companies in the same industry or sector. The price of a company’s stock may also be affected by changes in financial markets that are relatively unrelated to the company, such as changes in interest rates, currency exchange rates or industry regulation. Companies that elect to pay dividends on their common stock generally only do so after they invest in their own business and make required payments to bondholders and on other debt and preferred stock. Therefore, the value of a company’s common stock will usually be more volatile than its bonds, other debt and preferred stock. Common stock may be exchange-traded or over-the-counter (“OTC”). OTC stock may be less liquid than exchange-traded stock.

Convertible Securities

Convertible securities include corporate bonds, notes, preferred stock or other securities that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula. A convertible security entitles the holder to receive

32

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

interest paid or accrued on debt or dividends paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. While no securities investment is without some risk, investments in convertible securities generally entail less risk than the issuer’s common stock, although the extent to which such risk is reduced depends in large measure upon the degree to which the convertible security sells above its value as a fixed-income security. The market value of convertible securities tends to decline as interest rates increase and, conversely, to increase as interest rates decline. While convertible securities generally offer lower interest or dividend yields than nonconvertible debt securities of similar quality, they do enable the investor to benefit from increases in the market price of the underlying common stock. Holders of convertible securities have a claim on the assets of the issuer prior to the common stockholders, but may be subordinated to holders of similar non-convertible securities of the same issuer. Because of the conversion feature, certain convertible securities may be considered equity equivalents.

Corporate debt and other fixed-income securities.

Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that their value will generally decline as prevailing interest rates rise, which may cause a Fund’s net asset value to likewise decrease, and vice versa. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. Fixed-income securities are also subject to credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.

Delayed Funding Loans and Revolving Credit Facilities

A Fund may enter into, or acquire participations in, delayed funding loans and revolving credit facilities. Delayed funding loans and revolving credit facilities are borrowing arrangements in which the lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. A revolving credit facility differs from a delayed funding loan in that as the borrower repays the loan, an amount equal to the repayment may be borrowed again during the term of the revolving credit facility. Delayed funding loans and revolving credit facilities usually provide for floating or variable rates of interest. These commitments may have the effect of requiring a Fund to increase its investment in a company at a time when it might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). To the extent that a Fund is committed to advance additional funds, it will at all times segregate or “earmark” assets, determined to be liquid in accordance with procedures established by the Trust’s Board, in an amount sufficient to meet such commitments.

A Fund may invest in delayed funding loans and revolving credit facilities with credit quality comparable to that of issuers of its securities investments. Delayed funding loans and revolving credit facilities may be subject to restrictions on transfer, and only limited opportunities may exist to resell such instruments. As a result, a Fund may be unable to sell such investments at an opportune time or may have to resell them at less than fair market value.

Floating Rate Loan Interests

Floating rate loan interests held by the Funds are typically issued to companies (the “borrower”) by banks, other financial institutions, and privately and publicly offered corporations (the “lender”). Floating rate loan interests are generally non-investment grade, often involve borrowers whose financial condition is troubled or uncertain and companies that are highly leveraged. The Funds may invest in obligations of borrowers who are in bankruptcy proceedings. Floating rate loan interests may include fully funded term loans or revolving lines of credit. Floating rate loan interests are typically senior in the corporate capital structure of the borrower. Floating rate loan interests generally pay interest at rates that are periodically determined by reference to a base lending rate plus a premium. The base lending rates are generally the lending rate offered by one or more European banks, such as the London Interbank Offered Rate (“LIBOR”), the prime rate offered by one or more U.S. banks or the certificate of deposit rate. Floating rate loan interests may involve foreign borrowers, and investments may be denominated in foreign currencies. The Funds considers these investments to be investments in debt securities for purposes of its investment policies.

33

February 28, 2017 (Unaudited)

When the Funds purchase a floating rate loan interest it may receive a facility fee and when it sells a floating rate loan interest, it may pay a facility fee. On an ongoing basis, the Funds may receive a commitment fee based on the undrawn portion of the underlying line of credit amount of a floating rate loan interest. Facility and commitment fees are typically amortized to income over the term of the loan or term of the commitment, respectively. Consent and amendment fees are recorded to income as earned. Prepayment penalty fees, which may be received by the Funds upon the prepayment of a floating rate loan interest by a borrower, are recorded as realized gains. The Funds may invest in multiple series or tranches of a loan. A different series or tranche may have varying terms and carry different associated risks.

Floating rate loan interests are usually freely callable at the borrower’s option. The Funds may invest in such loans in the form of participations in loans (“Participations”) or assignments (“Assignments”) of all or a portion of loans from third parties. Participations typically will result in the Funds having a contractual relationship only with the lender, not with the borrower. The Funds will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the Participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing Participations, the Funds generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights of offset against the borrower, and the Funds may not benefit directly from any collateral supporting the loan in which it has purchased the Participation. As a result, the Funds will assume the credit risk of both the borrower and the lender that is selling the Participation. The Funds’ investment in Participations involves the risk of insolvency of the financial intermediaries who are parties to the transactions. In the event of the insolvency of the lender selling the Participation, the Funds may be treated as a general creditor of the lender and may not benefit from any offset between the lender and the borrower. Assignments typically result in the Funds having a direct contractual relationship with the borrower, and the Funds may enforce compliance by the borrower with the terms of the loan agreement.

In connection with floating rate loan interests, the Funds may also enter into unfunded floating rate loan interests (“commitments”). In connection with these commitments, the Funds earns a commitment fee, typically set as a percentage of the commitment amount. Such fee income, which is included in “Interest income” in the Statements of Operations, is recognized ratably over the commitment period. Unfunded floating rate loan interests are marked-to-market daily, and any unrealized appreciation (depreciation) is included in the Statements of Assets and Liabilities and Statements of Operations.

Foreign Debt Securities

The Funds may invest in foreign fixed and floating rate income securities (including emerging market securities) all or a portion of which may be non-U.S. dollar denominated and which include: (a) debt obligations issued or guaranteed by foreign national, provincial, state, municipal or other governments with taxing authority or by their agencies or instrumentalities, including Brady Bonds; (b) debt obligations of supranational entities; (c) debt obligations of the U.S. Government issued in non-dollar securities; (d) debt obligations and other fixed income securities of foreign corporate issuers (both dollar and non-dollar denominated); and (e) U.S. corporate issuers (both Eurodollar and non-dollar denominated). Investing in the securities of foreign issuers involves special considerations that are not typically associated with investing in the securities of U.S. issuers. In addition, emerging markets are markets that have risks that are different and higher than those in more developed markets.

Foreign Securities

The Funds may invest in U.S. dollar-denominated and non-U.S. dollar denominated equity and debt securities of foreign issuers and foreign branches of U.S. banks, including negotiable CDs, bankers’ acceptances, and commercial paper. Foreign issuers are issuers organized and doing business principally outside the United States and include corporations, banks, non-U.S. governments, and quasi-governmental organizations. While investments in foreign securities are intended to reduce risk by providing further diversification, such investments involve sovereign and other risks, in addition to the credit and market risks normally associated with domestic securities. These additional risks include the possibility of adverse political and economic developments (including political or social instability, nationalization, expropriation, or confiscatory taxation); the potentially adverse effects of

34

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

unavailability of public information regarding issuers, less governmental supervision and regulation of financial markets, reduced liquidity of certain financial markets, and the lack of uniform accounting, auditing, and financial reporting standards or the application of standards that are different or less stringent than those applied in the United States; different laws and customs governing securities tracking; and possibly limited access to the courts to enforce a Fund’s rights as an investor.

Payment-In-Kind Securities

The SiM HYO 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 (depreciation) of investments” to “Dividend and interest receivable” in the Statements of Assets and Liabilities.

Inflation-Indexed Bonds

The SiM HYO 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 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.

Illiquid and 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 (the “Securities Act”). Illiquid securities have included securities that have not been registered under the Securities Act, securities that are otherwise not readily marketable, and repurchase agreements having a remaining maturity of longer than seven calendar days. Disposal of both illiquid and restricted securities may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult to achieve. Illiquid and restricted securities outstanding at the period ended February 28, 2017 are disclosed in the Notes to the Schedules of Investments.

High-Yield Securities

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

35

American Beacon Funds^SM

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.

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, the Fund’s shareholders indirectly will bear the Fund’s proportionate share of the fees and expenses paid by shareholders of the other investment company, in addition to the fees and expenses the Fund’s 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 each 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.

5. Financial Derivative Instruments

The Funds may utilize derivative instruments to manage liquidity. When considering the Funds’ use of derivatives, it is important to note that the Funds do not use derivatives for the purpose of creating financial leverage.

Futures Contracts

Futures contracts are contracts to buy or sell a standard quantity of securities at a specified price on a future date. 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 Funds are 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 reflect 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 period ended February 28, 2017, the SIM HYO Fund entered into future contracts primarily for return enhancement, hedging and exposing cash to markets.

6. Principal Risks

Investing in the Funds may involve certain risks including, but not limited to, those described below:

Callable Securities Risk

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

Credit Risk

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

37

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

Futures Contracts Risk

Futures contracts are derivative instruments where one party pays a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Funds to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index, which will increase the volatility of the Funds and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract).

Floating Rate Securities Risk

The interest rates payable on floating rate securities are not fixed and may fluctuate based upon changes in market rates. The interest rate on a floating rate security is a variable rate which is tied to another interest rate, such as a money-market index or Treasury bill rate. Floating rate securities are subject to interest rate risk and credit risk. As short-term interest rates decline, interest payable on floating rate securities typically decreases. Alternatively, during periods of rising interest rates, interest payable on floating-rate securities typically increases. Changes in the interest rates of floating rate securities may lag behind changes in market rates or may have limits on the maximum increases in interest rates. The value of floating rate securities may decline if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline.

High-Yield Securities Risk

Investing in high-yield, below investment-grade securities (commonly referred to as “junk bonds”) generally involves significantly greater risks of loss of your money than an investment in investment-grade-securities. High-yield debt securities may fluctuate more widely in price and yield and may fall in price when the economy is weak or expected to become weak. High-yield securities are considered to be speculative with respect to an issuer’s ability to pay interest and principal and carry a greater risk that the issuers of lower-rated securities will default on the timely payment of principal and interest. Below-investment-grade securities may experience greater price volatility and less liquidity than investment-grade securities.

Interest Rate Risk

The Funds are subject to the risk that the market value of fixed-income securities it holds will decline due to rising interest rates. Generally, the value of investments with interest rate risk, such as fixed-income securities, will move in the opposite direction as movements in interest rates. The Federal Reserve raised the federal funds rate in December 2016, marking only the second such interest rate hike in nearly a decade. The Federal Reserve has signaled additional increases in 2017. Interest rates may rise, perhaps significantly and/or rapidly, potentially resulting in substantial losses to the Fund. The prices of fixed-income securities are also affected by their durations. Fixed-income securities with longer duration generally have greater sensitivity to changes in interest rates.

Liquidity Risk

The Funds are susceptible to the risk that certain of the floating rate debt securities held by the Funds, such as structured notes and other derivative instruments, may have limited marketability or be subject to restrictions on sale, and may be difficult or impossible to purchase or sell at favorable times or prices. The Funds could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Funds. The Funds may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Funds. For example, the Funds may be forced to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

Loan Interests Risk

Unlike publicly traded common stocks which trade on national exchanges, there is no central place or exchange for loans, including bank loans and senior loans, to trade. Loans trade in an over-the-counter market, and confirmation and settlement, which are effected through standardized procedures and documentation, may take significantly longer than seven days to complete. Extended trade settlement periods may, in unusual market conditions with a high volume of shareholder redemptions, present a risk to shareholders regarding a Fund’s ability to pay redemption proceeds within the allowable time periods stated in its prospectus. The secondary market for floating rate loans also may be subject to irregular trading activity and wide bid/ask spreads. The lack of an active trading market for certain loans may impair the ability of a Fund to sell its loan interests at a time when it may otherwise be desirable to do so or may require a Fund to sell them at prices that are less than what a Fund regards as their fair market value and may make it difficult to value such loans. Interests in loans made to finance highly leveraged companies or transactions, such as corporate acquisitions, may be especially vulnerable to adverse changes in economic or market conditions. When a Fund’s loan interest is a participation, the Fund is subject to the risk that the party selling the participation interest will not remit a Fund’s pro rata share of loan payments to the Fund, and the Fund may have less control over the exercise of remedies than the party selling the participation interest.

Market Risk

Since the financial crisis that started in 2008, the U.S. and many foreign economies continue to experience its after-effects, which have resulted, and may continue to result, in fixed-income instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. These events have reduced the willingness and ability of some lenders to extend credit, and have made it more difficult for some borrowers to obtain financing on attractive terms, if at all. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

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

Other Investment Companies Risk

The Funds may invest in shares of other registered investment companies, including money market funds. To the extent that the Funds invests in shares of other registered investment companies, you will indirectly bear fees and expenses charged by those investment companies in addition to the Fund’s direct fees and expenses and will be subject to the risks associated with investments in those funds. Money market funds are subject to interest rate risk, credit risk, and market risk.

Prepayment Risk

Prepayment risk is the risk that the principal amount of a bond may be repaid prior to the bond’s maturity date. Due to a decline in interest rates or excess cash flow, a debt security may be called otherwise prepaid before maturity. If this occurs, no additional interest will be paid on the investment and a Fund may have to invest at a lower rate, may not benefit from an increase in value that may result from declining interest rates, and may lose any premium it paid to acquire the security. Variable and floating rate securities may be less sensitive to prepayment risk.

Unrated Securities Risk

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

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 the report date, February 28, 2017.

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 unrecorded tax liabilities in the accompanying financial statements. The tax years for the periods ended August 31, 2013, 2014, 2015, and 2016 remain subject to examination by the Internal Revenue Service. If applicable, the Funds recognize 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.

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 tax character of distributions paid were as follows:

	SiM HYO Fund				Sound Point Fund

As of February 28, 2017, the components of distributable earnings (deficit) on a tax basis were as follows:

	SiM HYO Fund			Sound Point Fund
Cost basis of investments for federal income tax purposes	$	1,199,720,804		$	690,866,892
Unrealized appreciation		41,416,912			3,952,686
Unrealized depreciation		(26,410,142	)		(1,459,861	)
Net unrealized appreciation (depreciation)		15,006,770			2,492,825
Undistributed ordinary income		—			974,091
Undistributed long-term capital gains		—			—
Accumulated capital and other losses		(14,781,684	)		—
Other temporary differences		(374,695	)		(119,256	)
Distributable earnings (deficits)	$	(149,609	)	$	3,347,660

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 (depreciation) are attributable primarily to the tax deferral of losses from wash sales, the realization for tax purposes of unrealized gains (losses) on certain derivative instruments, the realization for tax purposes of unrealized gains (losses) on investments in passive foreign investment companies, and reclassifications of income from real estate investment securities and master limited partnerships.

Due to inherent differences in the recognition of income, expenses and realized gains (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 reclassified amounts represent current year permanent differences derived from foreign currency, reclassifications of income from real estate investment securities and publicly traded partnerships, dividend reclasses, and return of capital distributions as of February 28, 2017:

	SiM HYO Fund			Sound Point Fund
Paid-in-capital	$	(6,334,151	)	$	—
Undistributed net investment income (loss)		5,721,202			—
Accumulated net realized gain (loss)		612,949			—
Unrealized appreciation (depreciation) of investments in futures contracts		—			—

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 February 28, 2017, SiM HYO Fund has $3,042,166 of short-term and $11,739,518 of long term post RIC MOD capital loss carryforwards. The Fund utilized $2,588,974 short-term post RIC MOD capital loss carryforwards.

8. Investment Transactions

The aggregate cost of purchases and proceeds from sales of investments, other than short-term obligations, for the six months ended February 28, 2017 were as follows:

	Purchases		Sales
SiM HYO Fund (excluding U.S. Government Securities)	$	400,323,396	$	331,168,857
Sound Point Fund (excluding U.S. Government Securities)		485,845,315		127,468,390

FLEXIBLE BOND FUND

Investing in derivative instruments involves liquidity, credit, interest rate and market risks.

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.

President’s Message

Dear Shareholders,   In the weeks ahead of the U.S. presidential election on November 8, 2016, uncertainty about the outcome caused many investors to stay on the sidelines. Some investors questioned whether the election’s result would have negative consequences for their portfolios, although elections have rarely had a lasting effect on the market.   Following the election, the markets responded positively to aspects of the incoming administration’s proposed plans for economic growth; i.e., repatriating jobs from overseas, relaxing regulations, lowering taxes and increasing infrastructure spending. From Election Day 2016 to Inauguration Day 2017, the S&P 500 Index—a broad measure of the performance of large U.S. companies—climbed approximately 6%. From Inauguration Day to February 28, it gained approximately 4%.

Economists anticipated the Federal Reserve would increase the federal funds rate—perhaps as early as mid-March. The Federal Open Market Committee’s confidence in the improving U.S. economy was exhibited in December 2016 when short-term interest rates increased by 0.25% to a range of 0.50% to 0.75%. It was the second increase since 2008; the first increase occurred in December 2015.

For the six-month period that ended February 28, 2017, the Bloomberg Barclays U.S. Aggregate Index, a benchmark for investment-grade U.S. bonds, returned -2.19%. In contrast, during the same period, the Bank of America Merrill Lynch 3 Month LIBOR Constant Maturity Index, a widely used benchmark for short-term interest rates, returned 0.42%; and the Bank of America Merrill Lynch U.S. High Yield Master II Index, which represents domestic, below-investment-grade corporate debt, returned 5.54%.

For the 6 months ended February 28, 2017:

• American Beacon Flexible Bond Fund (Investor Class) returned 2.05%.

At American Beacon Advisors, we are proud to offer a broad range of global equity and fixed-income funds sub-advised by experienced asset managers who employ distinctive investment processes to manage assets through a variety of economic and market conditions. Together, we work diligently to help our shareholders meet their long-term financial goals.

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

Performance Overview

February 28, 2017 (Unaudited)

The Investor Class of the Flexible Bond Fund (the “Fund”) returned 2.05% for the six months ended February 28, 2017. The Fund outperformed the Bloomberg Barclays U.S. Aggregate Index return of -2.19% and the BofA Merrill Lynch 3 Month LIBOR Constant Maturity Index return of 0.42% for the same period.

Total Returns for the Period ended February 28, 2017

1. Performance shown is historical and is not indicative of future returns. Investment returns and principal value will vary, and shares may be worth more or less at redemption than at original purchase. Performance shown is 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.

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

3. The BofA Merrill Lynch 3 Month LIBOR Constant Maturity 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 Bloomberg Barclays U.S. Aggregate Index is a market weighted index of government, corporate, mortgage-backed and asset-backed fixed-rate debt securities of all maturities.

4. The Total Annual Fund Operating Expense ratios set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A and C Class shares was 1.14%, 1.20%, 1.43%, 1.53%, and 2.27%, 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 performed well during the period producing positive returns while interest rates rose and the broader bond market (Bloomberg Barclays Aggregate) was negative. The Fund’s duration remained under two years, which was a significant factor in protecting it from rising interest rates. By comparison, the Bloomberg Barclays U.S. Aggregate Index duration ended the period at 6.0 years. Additionally, a large portion of the Fund’s core holdings were global corporate, sovereign and asset-backed securities, which provided incremental yield and performed strongly as credit spreads tightened during the period. Overall, the Fund’s weighted-average credit quality remained investment grade.

Within currencies, the Fund reported gains in its short positions in the euro and Japanese yen, both of which declined in value relative to the U.S. dollar due to their soft economies, central bank easing, and concern over trade protectionism in the U.S. These have been long-standing short positions in the Fund.

The Fund reported losses, however, in its long currency positions in peripheral Europe (non-Euro currencies), the Mexican peso, the British pound and the Malaysian ringgit, all of which declined during the period relative to the U.S. dollar. European exposures were harmed by the surprise Brexit vote and soft economic growth, the peso retreated after Trump’s surprise election victory, and the ringgit was harmed, as were most emerging markets, by trade protectionism rhetoric in the U.S. These long positions have also been maintained for several quarters as their fundamental attractiveness continues. Unfortunately, headline risk continues to cause uncertainty in these markets.

Performance Overview

February 28, 2017 (Unaudited)

During the period, the Fund’s overall currency exposures benefitted total returns, primarily due to the short positions in the yen and Euro.

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

Expense Example

February 28, 2017 (Unaudited)

Fund Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption fees if applicable, and (2) ongoing costs, including management fees, administrative service fees, distribution (12b-1) fees, and other Fund expenses. The Examples are intended to help you understand the ongoing costs (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 September 1, 2016 through February 28, 2017.

Actual Expenses

The “Actual” lines of the tables 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 = $8.60), then multiply the result by the “Expenses Paid During Period” for the applicable Fund to estimate the expenses you paid on your account during this period. Shareholders of the Institutional and Investor Classes that invest in the Fund through an IRA or Roth IRA may be subject to a custodial IRA fee of $15 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $15 higher.

Hypothetical Example for Comparison Purposes

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

* Expenses are equal to the Fund’s annualized expense ratios for the six-month period of 0.90%, 0.99%, 1.27%, 1.30% and 2.05% 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 (181) by days in the year (365) to reflect the half-year period.

** 5% return before expenses.

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

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

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

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

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

Notes to Financial Statements

February 28, 2017 (Unaudited)

1. Organization and Significant Accounting Policies

American Beacon Funds (the “Trust”), is organized as a Massachusetts business trust. The Fund, a series within the Trust, is registered under the Investment Company Act of 1940, as amended (the “Act”), as a non-diversified, open-end management investment company. As of February 28, 2017, the Trust consists of twenty-seven active series, one of which is presented in this filing (the “Fund”): American Beacon Flexible Bond Fund. The remaining twenty-six active series are reported in separate filings.

American Beacon Advisors, Inc. (the “Manager”) is a wholly-owned subsidiary of Resolute Investment Managers, Inc., which is indirectly owned by investment funds affiliated with Kelso & Company, L.P. and Estancia Capital Management, LLC, and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services to the Trust and other investors.

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

New Accounting Pronouncements

In October 2016, the SEC adopted amendments to rules under the Investment Company Act of 1940 (“final rules”) intended to modernize the reporting and disclosure of information by registered investment companies. The final rules amend Regulation S-X and require funds to provide standardized, enhanced derivative disclosure in fund financial statements in a format designed for individual investors. The amendments to Regulation S-X also update the disclosures for other investments and investments in, and advances to affiliates and amend the rules regarding the general form and content of fund financial statements. The compliance date for the amendments to Regulation S-X is August 1, 2017. Management is currently evaluating the amendments and its impact, if any, on the fund’s financial statements.

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	Eligible Investors	Minimum Initial Investments
Institutional	Large institutional investors—sold directly or through intermediary channels.	$	250,000
Y Class	Large institutional retirement plan investors—sold directly or through intermediary channels.	$	100,000
Investor	All investors using intermediary organizations such as broker-dealers or retirement plan sponsors—sold directly through intermediary channels.	$	2,500
A Class	All investors who invest through intermediary organizations, such as broker-dealers or third party administrator. Retail investors who invest directly through a financial intermediary such as a broker, bank, or registered investment advisor, which may include a front-end sales charge and a contingent deferred sales charge (“CDSC”).	$	2,500
C Class	Retail investors who invest directly through a financial intermediary such as a broker or employee directed benefit plans with applicable sales charges, which may include CDSC.	$	1,000

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.

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

The following is a summary of significant accounting policies, consistently followed by the Fund in the preparation of the financial statements. The Fund is an investment company, and accordingly, follow the investment company accounting and reporting guidance of the Financial Accounting Standards Board Accounting Standard Codification Topic 946, Financial Services—Investment Companies, which is part of U.S. Generally Accepted Accounting Principles (“U.S. GAAP”).

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 net asset value (“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 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 Fund’s Statement of Operations.

Dividends to Shareholders

Dividends from net investment income of the Fund generally will be declared daily and paid monthly. Distributions, if any, of net realized capital gains are generally paid at least annually and recorded on the ex-dividend date. Dividends to shareholders are determined in accordance with federal income tax regulations, which may differ in amount and character from net investment income and realized gains recognized for purposes of U.S. GAAP.

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 six months ended February 28, 2017, the Fund did not have commission recapture income.

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.

Notes to Financial Statements

February 28, 2017 (Unaudited)

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 liabilities 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.

Concentration of Ownership

From time to time, the Fund may have a concentration of one or more accounts constituting a significant percentage of shares outstanding. Investment activities by holders of accounts that represent a controlling ownership of more than 5% of the Fund’s outstanding shares could have a material impact on the Fund. As of February 28, 2017, based on management’s evaluation of the shareholder account base, four accounts in the Fund have been identified as representing an unaffiliated controlling ownership of approximately 34% of the Fund’s outstanding shares.

2. Transactions with Affiliates

Management Agreement

The Fund and the Manager are parties to a Management Agreement that obligates the Manager to provide investment advisory, fund management, and administrative services to the Fund. As compensation for performing the duties under the Management Agreement, the Manager receives from the Fund an annualized fee at the following annual rates as a percentage of average daily net assets: 0.35% of the first $15 billion, 0.325% of the next $15 billion, and 0.30% over $30 billion. The Fund also pays the unaffiliated investment advisors hired to direct investment activities of the Fund an annualized investment advisory fee based on a percentage of the Fund’s average daily assets. Management fees paid by the Fund during the six months ended February 28, 2017 were as follows:

Fund	Management Fee Rate			Management Fee		Amounts paid to Investment Advisors		Amounts Paid to Manager
Flexible Bond		0.90	%	$	580,812	$	343,053	$	237,759

Distribution Plans

The Fund, except for the A and C Classes, has adopted a “defensive” Distribution Plan (the “Plan”) in accordance with Rule 12b-1 under the Act, pursuant to which no separate fees will be charged to the Fund for distribution purposes. However, the Plan authorizes the management fees received by the Manager and the investment advisors hired by the Manager to be used for distribution purposes. Under this Plan, the Fund does not intend to separately 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,

27

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

the Manager receives an annualized 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. 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 an annualized fee up to 0.10% of the average daily net assets of the Y Class, up to 0.25% 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.

Sub-Transfer Agent Fees

The Manager has entered into agreements, which include servicing agreements, with financial intermediaries that provide recordkeeping, processing, shareholder communications and other services to customers of the intermediaries that hold positions in the Institutional Class of the Fund and has agreed to compensate the intermediaries for providing these services. Intermediaries transact with the Fund primarily through the use of omnibus accounts on behalf of their customers who hold positions in the Fund. Certain services would have been provided by the Fund’s transfer agent and other service providers if the shareholders’ accounts were maintained directly by the Fund’s transfer agent. Accordingly, the Fund, pursuant to the Trust’s Board of Trustees (the “Board”) approval, have agreed to reimburse the Manager for all or a portion of the servicing fees paid to these intermediaries for the Institutional Class. The reimbursement amounts (sub-transfer agent fees) paid to the Manager are subject to a fee limit of up to 0.10% of an intermediary’s average net assets in the Institutional Class on an annual basis. For the six months ended February 28, 2017, the sub-transfer agent fees, as included in “Transfer agent fees” on the Statement of Operations, were as follows:

Fund	Sub-Transfer Agent Fees
Flexible Bond	$	12,559

As of February 28, 2017, the Fund owed the Manager the following reimbursements of sub-transfer agent fees, as included in “Transfer agent fees payable” on the Statement of Assets and Liabilities:

Fund	Reimbursement of Sub-Transfer Agent Fees
Flexible Bond	$	1,527

Investment in Affiliated Funds

The Fund may invest in the American Beacon U.S. Government Money Market Select Fund (the “USG Select Fund”). The Fund and the USG Select Fund have the same investment advisor and therefore, are considered to be affiliated. The Manager serves as the investment advisor to the USG Select Fund and receives management fees totaling 0.10% of the average daily net assets of the USG Select Fund. During the six months ended February 28, 2017, the Manager earned fees on the Fund’s direct investments in the USG Select Fund as shown below:

Fund	Direct Investments In USG Select Fund
Flexible Bond	$	4,560

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

28

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

an interfund lending program. This program provides an alternative credit facility allowing the Fund to borrow from other participating Fund. During the six months ended February 28, 2017, 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 exceed the Fund’s expense cap. For the six months ended February 28, 2017, the Manager waived or reimbursed expenses as follows:

Fund	Class	Expense Cap 9/1/2016 to 2/28/2017			Reimbursed Expenses		Expiration
Flexible Bond	Institutional		0.90	%	$	99,696		2020
Flexible Bond	Y		0.99	%		29,455		2020
Flexible Bond	Investor		1.27	%		1,882		2020
Flexible Bond	A		1.29	%		9,272		2020
Flexible Bond	C		2.04	%		3,174		2020

Of these amounts, $19,918 was disclosed as a receivable from the Manager on the Statement of Assets and Liabilities at February 28, 2017. The Fund has 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’ 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 Fund has not recorded a liability for these potential reimbursements due to the current assessment that reimbursements are unlikely. The reimbursed expenses listed above expire in 2020.

The carryover of excess expenses potentially reimbursable to the Manager are as follows:

Fund	Recovered Expenses		Excess Expense Carryover		Expiration of Reimbursed Expenses
Flexible Bond	$	—	$	854,833		2017
Flexible Bond		—		274,583		2018
Flexible Bond		—		395,527		2019

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. During the six months ended February 28, 2017, Foreside collected $4 in sales commissions from the sale of A Class shares for the Fund.

A 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 six months ended February 28, 2017, there were no CDSC fees collected for Class A Shares of 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 six months ended February 28, 2017, CDSC fees of $600 were collected for the Fund for Class C Shares.

Trustee Fees and Expenses

As compensation for their service to the Trust and the American Beacon Select Funds Trust, each Trustee receives an annual retainer of $120,000, plus $5,000 for each Board of Trustee meeting attended in person or via teleconference, $2,500 for attendance by Committee members at meetings of the Audit Committee and the Investment Committee, and $1,500 for attendance by Committee members at meetings of the Nominating and Governance Committee, plus reimbursement of reasonable expenses incurred in attending Board meetings, Committee meetings, and relevant educational seminars. The Trustees also may be compensated for attendance at special Board and/or Committee meetings from time to time. The Board Chairman receives an additional annual retainer of $50,000 as well as a single $5,000 fee each quarter for his attendance at the Committee meetings. The chairpersons of the Audit Committee and the Investment Committee each receive an additional annual retainer of $25,000 and the Chairman of the Nominating and Governance Committee receives an additional annual retainer of $10,000. These expenses are allocated on a prorated basis to each Fund of the Trust according to its respective net assets.

3. Security Valuation and Fair Value Measurements

Investments are valued at the close of the New York Stock Exchange (the “Exchange”), normally 4:00 p.m. Eastern Time, 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 are normally valued on the basis of prices provided by an independent pricing service and may take into account appropriate factors such as trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The prices of debt securities may be determined using quotes obtained from brokers.

Investments in open-end mutual funds are valued at the closing 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.

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 its 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. 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 Fund’s pricing time of 4:00 p.m. Eastern time. The earlier close of these foreign markets gives rise to the possibility that significant

30

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

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 American Depositary Receipts (“ADRs”) and futures 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 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 fair 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. Fixed-income securities are considered Level 2 as they are valued using observable inputs.
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.

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

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

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

Common stocks, ETFs and financial derivative instruments, such as futures contracts, 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.

The Fund’s investments are summarized by level based on the inputs used to determine their values. As of February 28, 2017, the investments were classified as described below:

U.S. GAAP also requires all transfers between any levels to be disclosed. The end of period timing recognition has been adopted for the transfers between levels of each Fund’s assets and liabilities. During the six months ended February 28, 2017, there were no transfers between levels.

4. Securities and Other Investments

Foreign Debt Securities

A Fund may invest in foreign fixed and floating rate income securities (including emerging market securities) all or a portion of which may be non-U.S. dollar denominated and which include: (a) debt obligations issued or guaranteed by foreign national, provincial, state, municipal or other governments with taxing authority or by their agencies or instrumentalities, including Brady Bonds; (b) debt obligations of supranational entities; (c) debt obligations of the U.S. Government issued in non-dollar securities; (d) debt obligations and other fixed income securities of foreign corporate issuers (both dollar and non-dollar denominated); and (e) U.S. corporate issuers (both Eurodollar and non- dollar denominated). There is no minimum rating criteria for a Fund’s investments in such securities. Investing in the securities of foreign issuers involves special considerations that are not typically associated with investing in the securities of U.S. issuers. In addition, emerging markets are markets that have risks that are different and higher than those in more developed markets.

Bank Loans and Senior Loans

Loans are typically administered by a bank, insurance company, finance company or other financial institution (the “agent”) for a lending syndicate of financial institutions. In a typical loan, the agent administers the terms of the loan agreement and is responsible for the collection of principal and interest and fee payments from the borrower and the apportionment of these payments to all lenders that are parties to the loan agreement. In addition, an institution (which may be the agent) may hold collateral on behalf of the lenders. Typically, under loan agreements, the agent is given broad authority in monitoring the borrower’s performance and is obligated to use the same care it would use in the management of its own property. In asserting rights against a borrower, the Fund normally will be dependent on the willingness of the lead bank to assert these rights, or upon a vote of all the lenders to authorize the action. If an agent becomes insolvent, or has a receiver, conservator, or similar official appointed for it by the appropriate regulatory authority, or becomes a debtor in a bankruptcy proceeding, the agent’s appointment may be terminated and a successor agent would be appointed. If an appropriate regulator or court determines that assets held by the agent for the benefit of purchasers of loans are subject to the claims of the agent’s general or secured creditors, the Fund might incur certain costs and delays in realizing payment on a loan or suffer a loss of principal and/or interest. The Fund may be subject to similar risks when it buys a participation interest or an assignment from an intermediary.

Bank loans can be fixed and floating rate loans arranged through private negotiations between a company or a non-U.S. government and one or more financial institutions (lenders). The Fund may invest in senior loans, which are floating rate loans that hold a senior position in the capital structure of U.S. and foreign corporations,

33

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

partnerships or other business entities that, under normal circumstances, allow them to have priority of claim ahead of other obligations of a borrower in the event of liquidation. Bank loans and senior loans may be collateralized or uncollateralized. They pay interest at rates that float above, or are adjusted periodically based on, a benchmark that reflects current interest rates. The Fund may invest in such loans in the form of participations in loans and assignments of all or a portion of loans from third parties. In connection with purchasing participations in such instruments, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not benefit directly from any collateral supporting the loan in which it has purchased the participation. When the Fund purchases assignments from lenders, the Fund will acquire direct rights against the borrower on the loan.

Floating Rate Loan Interests

Floating rate loan interests held by the Fund are typically issued to companies (the “borrower”) by banks, other financial institutions, and privately and publicly offered corporations (the “lender”). Floating rate loan interests are generally non-investment grade, often involve borrowers whose financial condition is troubled or uncertain and companies that are highly leveraged. The Fund may invest in obligations of borrowers who are in bankruptcy proceedings. Floating rate loan interests may include fully funded term loans or revolving lines of credit. Floating rate loan interests are typically senior in the corporate capital structure of the borrower. Floating rate loan interests generally pay interest at rates that are periodically determined by reference to a base lending rate plus a premium. The base lending rates are generally the lending rate offered by one or more European banks, such as the London Interbank Offered Rate (“LIBOR”), the prime rate offered by one or more U.S. banks or the certificate of deposit rate. Floating rate loan interests may involve foreign borrowers, and investments may be denominated in foreign currencies. The Fund considers these investments to be investments in debt securities for purposes of its investment policies.

When the Fund purchases a floating rate loan interest it may receive a facility fee and when it sells a floating rate loan interest, it may pay a facility fee. On an ongoing basis, the Fund may receive a commitment fee based on the undrawn portion of the underlying line of credit amount of a floating rate loan interest. Facility and commitment fees are typically amortized to income over the term of the loan or term of the commitment, respectively. Consent and amendment fees are recorded to income as earned. Prepayment penalty fees, which may be received by the Fund upon the prepayment of a floating rate loan interest by a borrower, are recorded as realized gains. The Fund may invest in multiple series or tranches of a loan. A different series or tranche may have varying terms and carry different associated risks.

Floating rate loan interests are usually freely callable at the borrower’s option. The Fund may invest in such loans in the form of participations in loans (“Participations”) or assignments (“Assignments”) of all or a portion of loans from third parties. Participations typically will result in the Fund having a contractual relationship only with the lender, not with the borrower. The Fund will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the Participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing Participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights of offset against the borrower, and the Fund may not benefit directly from any collateral supporting the loan in which it has purchased the Participation. As a result, the Fund will assume the credit risk of both the borrower and the lender that is selling the Participation. The Fund’s investment in Participations involves the risk of insolvency of the financial intermediaries who are parties to the transactions. In the event of the insolvency of the lender selling the Participation, the Fund may be treated as a general creditor of the lender and may not benefit from any offset between the lender and the borrower. Assignments typically result in the Fund having a direct contractual relationship with the borrower, and the Fund may enforce compliance by the borrower with the terms of the loan agreement.

In connection with floating rate loan interests, the Fund may also enter into unfunded floating rate loan interests (“commitments”). In connection with these commitments, the Fund earns a commitment fee, typically

34

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

set as a percentage of the commitment amount. Such fee income, which is included in “Interest income” in the Statement of Operations, is recognized ratably over the commitment period. Unfunded floating rate loan interests are marked-to-market daily, and any unrealized appreciation (depreciation) is included in the Statement of Assets and Liabilities and Statement of Operations.

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. 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 if 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 sub-advisor, 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 the 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.

Payment-In-Kind Securities

The 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

35

Notes to Financial Statements

February 28, 2017 (Unaudited)

a dirty price) and require a pro-rata adjustment from the “Unrealized appreciation (depreciation) of investments” to “Dividend and interest receivable” in the Statement of Assets and Liabilities.

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 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.

Illiquid and 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 (the “Securities Act”). Illiquid securities have included securities that have not been registered under the Securities Act, securities that are otherwise not readily marketable, and repurchase agreements having a remaining maturity of longer than seven calendar days. Disposal of both illiquid and restricted securities may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult to achieve. Illiquid and restricted securities outstanding at the six months ended February 28, 2017, 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 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.

Commercial Paper

The Fund may invest in commercial paper and other short-term notes. Commercial paper refers to promissory notes representing an unsecured debt of a corporation or finance company with a fixed maturity of no more than 270 days. A variable amount master demand note (which is a type of commercial paper) represents a direct borrowing arrangement involving periodically fluctuating rates of interest under a letter agreement between a commercial paper issuer and an institutional lender pursuant to which the lender may determine to invest varying amounts.

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 Fund 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, the Fund becomes a shareholder of that investment company. As a result, the Fund’s shareholders indirectly will bear the Fund’s proportionate share of the fees and expenses paid by shareholders of the other investment company, in addition to the fees and expenses the Fund’s 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.

37

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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 the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”). 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 the 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 (“SPVs”) and other entities that acquire and package mortgage loans for resale as MBS. These privately issued non-agency MBS may offer higher yields than those issued by government agencies, but also may be subject to greater price changes than governmental issues. Subprime loans refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their loans. Alt-A loans refer to loans extended to borrowers who have incomplete documentation of income, assets, or other variables that are important to the credit underwriting processes. Non-conforming mortgages are loans that do not meet the standards that allow purchase by government-sponsored enterprises. MBS with exposure to subprime loans, Alt-A loans or non-conforming loans have had in many cases higher default rates than those loans that meet government underwriting requirements. The risk of non-payment is greater for MBS that are backed by mortgage pools that contain subprime, Alt-A and non-conforming loans, but a level of risk exists for all loans.

Unlike agency MBS issued or guaranteed by the U.S. government or a government-sponsored entity (e.g., Fannie Mae and Freddie Mac), 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.

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 the six months ended February 28, 2017, short positions held by the Fund are disclosed in the Notes to the Schedule of Investments are disclosed in the Notes to the Schedule of Investments and the Statement of Assets and Liabilities.

Master Agreements

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

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

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

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 Funds do 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

40

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

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.

For the six months ended February 28, 2017, the Fund purchased/sold options primarily for return enhancement and hedging.

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.

Average Purchased Option and Swaption Notional Amounts Outstanding

Average Written Option and Swaption Notional Amounts Outstanding

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

41

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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 negotiated between the Fund and a counterparty to exchange or swap investment cash flows, assets, foreign currencies, or market-linked returns at specified, future intervals. Swap agreements are privately negotiated in the over-the-counter market (“OTC Swaps”) or cleared in a central clearing house (“Centrally Cleared Swaps”). 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 premiums 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.

42

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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 agreement outstanding as of the six months ended February 28, 2017, for which the Fund is the seller of protection is disclosed in the Notes to the Schedule of Investments. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into by the Fund for the same referenced entity or entities.

For the six months ended February 28, 2017, the Fund entered into credit default swaps primarily for return enhancement, hedging and exposure to credit instruments.

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.

Average Credit Default Swap Notional Amounts Outstanding
Fund	Period ended February 28, 2017
Flexible Bond		5,921,375

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 six months ended February 28, 2017, the Fund entered into interest rate swaps primarily for return enhancement and hedging.

Over-the-Counter 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 six months ended February 28, 2017, the Fund did not hold 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.

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.

45

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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.

Forward Currency Contracts

The Funds may enter into forward 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 currency contracts are valued at the forward exchange rate prevailing on the day of valuation. The Funds bear 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 Funds also bear the credit risk if the counterparty fails to perform under the contract.

For the six months ended February 28, 2017, the Fund entered into forward currency exchange contracts primarily for return enhancement and hedging.

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

Fund	Purchased Contracts		Sold Contracts
Flexible Bond Fund		31,325,962		47,390,041

Futures Contracts

Futures contracts are contracts to buy or sell a standard quantity of securities at a specified price on a future date. 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.

6. Principal Risks

Investing in the Fund may involve certain risks including, but not limited to, those described below.

Counterparty Risk

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

Currency Risk

The Fund may have exposure to foreign currencies by making direct investments in non-U.S. currencies or in securities denominated in non-U.S. currencies, purchasing or selling forward currency exchange contracts in non-U.S. currencies, non-U.S. currency futures contracts and swaps for cross-currency investments. Foreign currencies will fluctuate, and may decline, in value relative to the U.S. dollar and other currencies and thereby affect the Fund’s investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, or in derivatives that provide exposure to, foreign (non-U.S.) currencies.

Derivatives Risk

Derivatives may involve significant risk. The use of derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities or other instruments underlying those derivatives, including the high degree of leverage often embedded in such instruments, and potential material and prolonged deviations between the theoretical value and realizable value of a derivative. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. Derivatives may be illiquid and may be more volatile than other types of investments. The Fund may buy or sell derivatives not traded on an exchange and which may be subject to heightened liquidity and valuation risk. Derivative investments can increase portfolio turnover and transaction costs. Derivatives also are subject to Counterparty Risk. As a result, the Fund may obtain no recovery of its investment or may only obtain a limited recovery, and any recovery may be delayed. Not all derivative transactions require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty.

Emerging Markets Risk

When investing in emerging markets, the risks of investing in foreign securities are heightened. Emerging markets are generally smaller, less developed, less liquid and more volatile than the securities markets of the U.S. and other developed markets. There are also risks of: greater political uncertainties; an economy’s dependence on revenues from particular commodities or on international aid or development assistance; currency transfer restrictions; a limited number of potential buyers for such securities; and delays and disruptions in securities settlement procedures.

Foreign Investing Risk

Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity and greater volatility, (4) lack of uniform accounting, auditing and financial reporting standards, (5) increased price volatility, (6) less government regulation and supervision of foreign stock exchanges, brokers and listed companies; and (7) delays in transaction settlement in some foreign markets.

Forward Currency Contracts Risk

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

Futures Contract Risk

Futures contracts are derivative investments pursuant to a contract with a counterparty to pay a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract).

High Portfolio Turnover Risk

Portfolio turnover is a measure of the Fund’s trading activity over a one-year period. A portfolio turnover rate of 100% would indicate that the Fund sold and replaced the entire value of its securities holdings during the period. High portfolio turnover could increase the Fund’s transaction costs, have a negative impact on performance, and generate higher capital gain distributions to shareholders than if the Fund has a lower portfolio turnover rate.

Leverage Risk

The Fund’s use of futures, forward contracts, swaps, other derivative instruments and selling securities short will have the economic effect of financial leverage. Financial leverage magnifies the exposure to the swings in prices of an asset or class of assets underlying a derivative instrument and results in increased volatility, which means that the Fund will have the potential for greater losses than if the Fund do not use the derivative instruments that have a leveraging effect. Leverage may result in losses that exceed the amount originally invested and may accelerate the rate of losses. Leverage tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset or class of assets and may cause the Fund’s NAV to be volatile.

Liquidity Risk

Liquidity risk is the risk that the Fund may not be able to dispose of securities or close out derivatives transactions readily at a favorable time or prices (or at all) or at prices approximating those at which the Fund currently value them. For example, certain investments are subject to restrictions on resale, may trade in the over-the-counter market or in limited volume, or may not have an active trading market. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. It may be difficult for the Fund to value illiquid securities accurately. The market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Disposal of illiquid securities may entail registration expenses and other transaction costs that are higher than those for liquid securities. The Fund may seek to borrow money to meet its obligations (including among other things redemption obligations) if it is unable to dispose of illiquid investments, resulting in borrowing expenses and possible leveraging of the Fund. In some cases, due to unanticipated levels of illiquidity the Fund may choose to meet its redemption obligations wholly or in part by distributions of assets in-kind.

Market Risk

Since the financial crisis that started in 2008, the U.S. and many foreign economies continue to experience its after-effects, which have resulted, and may continue to result, in fixed income instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. These events have reduced the willingness and ability of some lenders to extend credit, and have made it more difficult for some borrowers to obtain financing on attractive terms, if at all. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

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

Multiple Sub-Advisor Risk

The Manager may allocate the Fund’s assets among multiple sub-advisors, each of which is responsible for investing its allocated portion of the Fund’s assets. To a significant extent, the Fund’s performance will depend on the success of the Manager in allocating the Fund’s assets to sub-advisors and its selection and oversight of the sub-advisors. Because each sub-adviser manages its allocated portion of the Fund independently from another sub-adviser, the same security may be held in different portions of the Fund, or may be acquired for one portion of the Fund at a time when a sub-adviser to another portion deems it appropriate to dispose of the security from that other portion, resulting in higher expenses without accomplishing any net result in the Fund’s holdings. Similarly, under some market conditions, one sub-adviser may believe that temporary, defensive investments in short-term instruments or cash are appropriate when another sub-adviser believes continued exposure to the equity or debt markets is appropriate for its allocated portion of the Fund. Because each sub-adviser directs the trading for its

50

American Beacon Flexible Bond Fund^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

own portion of the Fund, and does not aggregate its transactions with those of the other sub-advisors, the Fund may incur higher brokerage costs than would be the case if a single sub-adviser were managing the entire Fund. In addition, while the Manager seeks to allocate the Fund’s assets among the Fund’s sub-advisors in a manner that it believes is consistent with achieving the Fund’s investment objective(s), the Manager may be subject to potential conflicts of interest in allocating the Fund’s assets among sub-advisors, because the Manager pays different fees to the sub-adviser and due to other factors that could impact the Manager’s revenues and profits.

Non-Diversification Risk

The Fund is non-diversified, which means the Fund may focus its investments in the securities of a comparatively small number of issuers. Investments in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if assets were diversified among the securities of a greater number of issuers.

Other Investment Companies Risk

The Fund may invest in shares of other registered investment companies, including exchange-traded funds (“ETFs”). To the extent that the Fund invest in shares of other registered investment companies, the shareholders will indirectly bear fees and expenses charged by the underlying funds in addition to the Fund’s direct fees and expenses and will be subject to the risks associated with investments in those funds. For example, ETF shares may trade at a premium or discount to their net asset value. An ETF that tracks an index may not precisely replicate the returns of its benchmark index.

Short Position Risk

The Fund will incur a loss as a result of a short position if the price of the instrument sold short increases in value between the date of the short sale and the date on which an offsetting position is purchased. Short positions may be considered speculative transactions and involve special risks, including greater reliance on the sub-advisor’s ability to accurately anticipate the future value of a security or instrument. The Funds’ losses are potentially unlimited in a short position transaction.

Valuation Risk

The Fund may value certain assets at a price different from the price at which they can be sold. This risk may be especially pronounced for investments, such as certain derivatives, which may be illiquid or which may become illiquid.

Offsetting Assets and Liabilities

The Fund is party to enforceable master netting agreements between brokers and counterparties, 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 Statement 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 February 28, 2017.

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 Fund does not have any unrecorded tax liabilities in the accompanying financial statements. The tax years for the periods ended August 31, 2013, 2014, 2015, and 2016 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 expenses” on the Statement of Operations.

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.

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 tax character of distributions paid were as follows:

C Class		—		20,519
Total distributions paid	$	1,443,976	$	8,441,616

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

As of February 28, 2017, the components of distributable earnings (deficit) on a tax basis were as follows:

Cost basis of investments for federal income tax purposes	$	147,664,831
Unrealized appreciation		1,951,027
Unrealized depreciation		(6,167,380	)
Net unrealized appreciation (depreciation)		(4,216,353	)
Undistributed ordinary income		525,074
Undistributed long-term capital gains		—
Accumulated capital and other losses		(15,811,298	)
Other temporary differences		180,356
Distributable earnings (deficits)	$	(19,322,221	)

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

Accordingly, the following reclassified amounts represent current year permanent differences derived from foreign currency, paydowns, swap income, and distributions as of February 28, 2017:

Paid-in-capital	$	—
Undistributed (over distribution of) net investment income (loss)		1,278,487

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. There can be no assurances that the investment objectives of this Fund will be met.

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. There can be no assurances that the investment objectives of this Fund will be met.

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

President’s Message

	Dear Shareholders, In the weeks ahead of the U.S. presidential election on November 8, 2016, uncertainty about the outcome caused many investors to stay on the sidelines. Some investors questioned whether the election’s result would have negative consequences for their portfolios, although elections have rarely had a lasting effect on the market.
	Following the election, the markets responded positively to aspects of the incoming administration’s proposed plans for economic growth; i.e., repatriating jobs from overseas, relaxing regulations, lowering taxes and increasing infrastructure spending. From Election Day 2016 to Inauguration Day 2017, the S&P 500 Index – a broad measure of the performance of large U.S. companies – climbed approximately 6%. From Inauguration Day to February 28, it gained approximately 4%.
Economists anticipated the Federal Reserve would increase the federal funds rate – perhaps as early as mid-March. The Federal Open Market Committee’s confidence in the improving U.S. economy was exhibited in December 2016 when short-term interest rates increased by 0.25% to a range of 0.50% to 0.75%. It was the second increase since 2008; the first increase occurred in December 2015.

For the six-month period that ended February 28, 2017, the Dow Jones Industrial Average, which follows the performance of 30 significant stocks trading on the New York Stock Exchange and The NASDAQ Stock Market, gained 14.51%; and the S&P 500 Index, a domestic equity bellwether, grew 10.01%. In contrast, during the same period, the Bloomberg Barclays Capital U.S. Aggregate Index, a benchmark for domestic corporate and government bonds, returned -2.19%; and the Bank of America Merrill Lynch U.S. High Yield Master II Index, which represents domestic, below-investment-grade corporate debt, returned 5.54%.

For the 6 months ended February 28, 2017:

• American Beacon The London Company Income Equity Fund (Investor Class) returned 7.12%.

• American Beacon Zebra Small Cap Equity Fund (Investor Class) returned 13.69%.

At American Beacon Advisors, we are proud to offer a broad range of global equity and fixed-income funds sub-advised by experienced asset managers who employ distinctive investment processes to manage assets through a variety of economic and market conditions. Together, we work diligently to help our shareholders meet their long-term financial goals.

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

4. The Total Annual Fund Operating Expense ratios set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A, and C Class shares was 0.76%, 0.83%, 1.07%, 1.14%, and 1.88%, respectively. The expense ratios above may vary from the expense ratios presented in other sections of this report that are based on expenses incurred during the period covered by this report.

The Fund’s underperformance relative to the Index was primarily attributable to security selection among the various economic sectors, and to a lesser extent, sector allocation.

From a security selection standpoint, the Fund’s holdings in the Financials, Information Technology and Materials sectors detracted from performance. In the Financials sector, the Fund’s absence from Bank of America and JP Morgan Chase, which were up 53.5% and 36.0%, respectively, in the Index, negatively impacted performance. Cincinnati Financial (down 4.2%) also detracted from performance in the Financials sector. In the Information Technology sector, CA (down 3.3%) was the largest detractor. The Fund’s larger allocation in New Market Corp (up 1.2%) and The Mosaic Company (up 6.7%), both of which underperformed the sector, hurt performance in the Materials sector. The aforementioned poor selection was somewhat offset by good security selection in the Industrials sector. Companies in the Industrials sector contributing to performance included Norfolk Southern (up 30.3%) and General Dynamics (up 25.8%).

From a sector allocation perspective, the Fund’s significant underweight in Financials, the best performing sector in the Index, detracted from performance. An overweight position in the Consumer Staples sector also detracted from the Fund’s return. Underweight positions in Real Estate and Energy, two of the poorer performing sectors, added relative value.

1. 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%.

2. Fund performance represents the total returns achieved by the Investor Class from 6/1/10 up to 9/1/10, the inception date of the C Class, and the returns of the C Class since its inception. Expenses of the C Class are higher than those of the Investor Class. As a result, total returns shown may be higher than they would have been had the C Class been in existence since 6/1/10. The maximum contingent deferred sales charge is 1.00% for shares redeemed within one year of the date of purchase.

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

4. The Russell 2000 Index is an unmanaged index comprised of approximately 2,000 smaller-capitalization stocks from various industrial sectors. Russell 2000 Index is a registered trademark of the Frank Russell Company. One cannot directly invest in an index.

5. The Total Annual Fund Operating Expense ratios set forth in the most recent Fund prospectus for the Institutional, Y, Investor, A and C Class shares was 1.54%, 1.59%, 1.75%, 1.91%, and 2.66%, 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 investment strategy is primarily focused on identifying fundamentally attractive companies with relatively low trading volumes. The sub-advisor believes that when these quality companies are recognized by investors, trading volumes are likely to increase and stock prices are likely to rise. Reporting attribution based on trading volume can be difficult; however, several traditional attribution factors are helpful in understanding the Fund’s returns.

During the quarter, the value segment of the small-cap market significantly outperformed growth. The Russell 2000 Index returned 12.61%, with the Russell 2000 Value Index returning 15.80%, and the Russell 2000 Growth Index returning 9.39%. The outperformance in value was primarily due to a recovery in Financials and in commodity-sensitive sectors (Energy and Materials) based on improved economic growth, rising interest rates, stable oil prices, and the surprise Trump election. The Fund invested significantly in value stocks.

The Fund’s allocation across sectors was generally in line with the Russell 2000 Index at +/-2% weights. The Fund did have a slight overweight (approximately 4%) in the Financial sector, which was one of the best performing sectors, but the strategy is not based on active sector allocation. The majority of performance is attributed to security selection – identifying fundamentally attractive companies with relatively low trading volumes.

American Beacon Zebra Small Cap Equity Fund^SM

Performance Overview

February 28, 2017 (Unaudited)

Market capitalization did not play a significant role during the period. The Fund’s weighted-average market capitalization of $1.6 billion was slightly smaller than that of the Russell 2000 Index, at $2.3 billion, but the market cap effect on returns was not as significant as the value/growth effect.

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.

Expense Examples

February 28, 2017 (Unaudited)

Fund Expense Example

As a shareholder of the Funds, you incur two types of costs: (1) transaction costs, such as sales charges (loads) on purchase payments and redemption fees, and (2) ongoing costs, including management fees, administrative service fees, distribution (12b-1) fees, and other Fund expenses. The Examples are intended to help you understand the ongoing cost (in dollars) of investing in the Funds 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 September 1, 2016 through February 28, 2017.

Actual Expenses

The “Actual” lines of the tables 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 = $8.60), then multiply the result by the “Expenses Paid During Period” for the applicable Fund to estimate the expenses you paid on your account during this period. Shareholders of the Institutional and Investor Classes that invest in the Funds through an IRA or Roth IRA may be subject to a custodial IRA fee of $15 that is typically deducted each December. If your account was subject to a custodial IRA fee during the period, your costs would have been $15 higher.

Hypothetical Example for Comparison Purposes

The “Hypothetical” lines of the tables 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 Funds 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 Institutional and Investor 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 tables 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.

Notes to Financial Statements

February 28, 2017 (Unaudited)

1. Organization and Significant Accounting Policies

American Beacon Funds (the “Trust”) is organized as a Massachusetts business trust. The Funds, each a series within the Trust, are registered under the Investment Company Act of 1940, as amended, (the “Act”) as diversified, open-end management investment companies. As of February 28, 2017, the Trust consists of twenty-seven active series, two of which are presented in this filing (collectively, the “Funds” and each individually a “Fund”): the American Beacon The London Company Income Equity Fund and the American Beacon Zebra Small Cap Equity Fund. The remaining twenty-five active series are reported in separate filings.

American Beacon Advisors, Inc. (the “Manager”) is a wholly-owned subsidiary of Resolute Investment Managers, Inc., which is indirectly owned by investment funds affiliated with Kelso & Company, L.P. and Estancia Capital Management, LLC, and was organized in 1986 to provide business management, advisory, administrative and asset management consulting services to the Trust and other investors.

New Accounting Pronouncements

In October 2016, the SEC adopted amendments to rules under the Investment Company Act of 1940 (“final rules”) intended to modernize the reporting and disclosure of information by registered investment companies. The final rules amend Regulation S-X and require funds to provide standardized, enhanced derivative disclosure in fund financial statements in a format designed for individual investors. The amendments to Regulation S-X also update the disclosures for other investments and investments in, and advances to affiliates and amend the rules regarding the general form and content of fund financial statements. The compliance date for the amendments to Regulation S-X is August 1, 2017. Management is currently evaluating the amendments and its impact, if any, on the Funds’ Financial Statements.

Class Disclosure

The Funds have multiple classes of shares designed to meet the needs of different groups of investors. However, not all Funds offer all classes. The following table sets forth the differences amongst the classes:

Class	Eligible Investors	Minimum Initial Investments
Institutional	Large institutional investors—sold directly or through intermediary channels.	$	250,000
Y Class	Large institutional retirement plan investors—sold directly or through intermediary channels.	$	100,000
Investor	All investors using intermediary organizations such as broker-dealers or retirement plan sponsors—sold directly through intermediary channels.	$	2,500
A Class	All investors who invest through intermediary organizations, such as broker-dealers or third party administrator. Retail investors who invest directly through a financial intermediary such as a broker, bank, or registered investment advisor, which may include a front-end sales charge and a contingent deferred sales charge (“CDSC”).	$	2,500
C Class	Retail investors who invest directly through a financial intermediary such as a broker or employee directed benefit plans with applicable sales charges, which may include CDSC.	$	1,000

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 administration fees, service fees, and distribution fees and vary amongst the classes as described more fully in Note 2.

The following is a summary of significant accounting policies, consistently followed by the Funds in preparation of the financial statements. The Funds are considered investment companies and accordingly,

22

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

follow the investment company accounting and reporting guidance of the Financial Accounting Standards Board

Accounting Standard Codification Topic 946, Financial Services—Investment Companies, which is part of U.S.

Generally Accepted Accounting Principles (“U.S. GAAP”).

Security Transactions and Investment Income

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

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. Dividends to shareholders are determined in accordance with federal income tax regulations, which may differ in amount and character from net investment income and realized gains recognized for purposes of U.S. GAAP. To the extent necessary to fully distribute capital gains, the Funds also designate earnings and profits distributed to shareholders on the redemption of shares.

Commission Recapture

The Funds 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

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.

Notes to Financial Statements

February 28, 2017 (Unaudited)

Concentration of Ownership

From time to time, the Funds may have a concentration of one or more accounts constituting a significant percentage of shares outstanding. Investment activities by holders of accounts that represent a controlling ownership of more than 5% of the Funds’ outstanding shares could have a material impact on the Funds. As of February 28, 2017, based on management’s evaluation of the shareholder account base, one account has been identified as representing one non-affiliated controlling ownership of approximately 7% of the Zebra Small Cap Equity Fund’s outstanding shares.

2. Transactions with Affiliates

Management Agreement

The Funds and the Manager are parties to a management agreement that obligates the Manager to provide investment advisory, fund management, and administrative services to the Funds. As compensation for performing the duties under the Management Agreement, the Manager receives from the Funds an annualized fee at the following annual rates as a percentage of average daily net assets: 0.35% of the first $5 billion, 0.325% of the next $5 billion, 0.30% of the next $10 billion, and 0.275% over $20 billion. The Funds pay the unaffiliated investment advisors hired to direct investment activities of the Funds an annualized investment advisory fee based on a percentage of the Funds’ average daily assets. Management fees paid by the Funds during the six months ended February 28, 2017 were as follows:

Fund	Management Fee Rate			Management Fee		Amounts paid to Investment Advisors		Amounts Paid to Manager
The London Company Income Equity		0.67	%	$	3,658,032	$	1,725,037	$	1,932,995
Zebra Small Cap Equity		0.89	%		143,247		86,946		56,301

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 of 10% 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 10% 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 six months ended February 28, 2017, securities lending fees paid to the Manager were $771 for the Zebra Small Cap Equity Fund.

Distribution Plans

The Funds, except for the A and C Classes, 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 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.

24

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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 an annualized fee up to 0.10% of the average daily net assets of Y Class, up to 0.15% of the average daily net assets of the A and C Classes, and up to 0.375% of the average daily net assets of the Investor Class of the Funds.

Sub-Transfer Agent Fees

The Manager has entered into agreements, which include servicing agreements, with financial intermediaries that provide recordkeeping, processing, shareholder communications and other services to customers of the intermediaries that hold positions in the Institutional Class of the Funds and has agreed to compensate the intermediaries for providing these services. Intermediaries transact with the Funds primarily through the use of omnibus accounts on behalf of their customers who hold positions in the Funds. Certain services would have been provided by the Funds’ transfer agent and other service providers if the shareholders’ accounts were maintained directly by the Funds’ transfer agent. Accordingly, the Funds, pursuant to the Trust’s Board of Trustees (the “Board”) approval, have agreed to reimburse the Manager for all or a portion of the servicing fees paid to these intermediaries for the Institutional Class. The reimbursement amounts (sub-transfer agent fees) paid to the Manager are subject to a fee limit of up to 0.10% of an intermediary’s average net assets in the Institutional Class on an annual basis. For the period ended February 28, 2017, the sub-transfer agent fees, as included in “Transfer agent fees” on the Statements of Operations, were as follows:

Fund	Sub-Transfer Agent Fees
The London Company Income Equity	$	22,003
Zebra Small Cap Equity		266

As of February 28, 2017, the Funds owed the Manager the following reimbursements of sub-transfer agent fees, as included in “Transfer agent fees payable” on the Statements of Assets and Liabilities:

Fund	Reimbursement of Sub-Transfer Agent Fees
The London Company Income Equity	$	3,788
Zebra Small Cap Equity		355

Investment in Affiliated Funds

The Funds may invest in the American Beacon U.S. Government Money Market Select Fund (the “USG Select Fund”). Cash collateral received by the Funds in connection with securities lending may also be invested in the USG Select Fund. The Funds and the USG Select Fund have the same investment advisor and therefore, are considered to be affiliated. The Manager serves as investment advisor to the USG Select Fund and receives management fees totaling 0.10% of its average daily net assets of the USG Select Fund. During the period ended February 28, 2017, the Manager earned fees on the Funds’ direct investments in the USG Select Fund as shown below:

Fund	Direct Investments in USG Select Fund		Securities Lending Collateral in USG Select Fund		Total
The London Company Income Equity	$	24,206	$	—	$	24,206
Zebra Small Cap Equity		462		147		609

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

25

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

from other participating funds. During the six months ended February 28, 2017, the Funds did not utilize the credit facility.

Expense Reimbursement Plan

The Manager contractually agreed to reimburse the classes of the Funds to the extent that total annual fund operating expenses exceed the Funds’ expense cap. For the six months ended February 28, 2017, the Manager waived or reimbursed expenses as follows:

Fund	Class	Expense Cap 9/1/2016 - 2/28/2017			Reimbursed Expenses		Expiration
Zebra Small Cap Equity	Institutional		0.89	%	$	4,514		2020
Zebra Small Cap Equity	Y		0.99	%		30,544		2020
Zebra Small Cap Equity	Investor		1.27	%		14,266		2020
Zebra Small Cap Equity	A		1.29	%		12,387		2020
Zebra Small Cap Equity	C		2.04	%		14,476		2020

Of these amounts, $9,915 was disclosed as a receivable from the Manager on the Statements of Assets and Liabilities at February 28, 2017 for the Zebra Small Cap Equity Fund. 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 2020. 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		Expiration
The London Company Income Equity	$	—	$	13,005		2017
Zebra Small Cap Equity Fund		—		94,922		2017
Zebra Small Cap Equity Fund		—		105,676		2018
Zebra Small Cap Equity Fund		—		130,345		2019

Sales Commissions

The Funds’ distributor, Foreside Fund Services, LLC (“Foreside”), may receive a portion of A Class sales charges from broker dealers and it may be used to offset distribution related expenses. For the six months ended February 28, 2017, Foreside collected $41,797 and $1,001 in sales commissions from the sale of Class A Shares for The London Company Income Equity and Zebra Small Cap Equity Funds, respectively.

A 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 six months ended February 28, 2017, fees of $299 were collected for The London Company Income Equity Fund for Class A Shares.

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 six months ended February 28, 2017, CDSC fees of $37,617 and $169 were collected for the Class A Shares of The London Company Income Equity and Zebra Small Cap Equity Funds, respectively.

Trustee Fees and Expenses

As compensation for their service to the Trust and the American Beacon Select Funds Trust, each Trustee receives an annual retainer of $120,000, plus $5,000 for each Board meeting attended in person or via teleconference, $2,500 for attendance by Committee members at meetings of the Audit Committee and the Investment Committee, and $1,500 for attendance by Committee members at meetings of the Nominating and Governance Committee, plus reimbursement of reasonable expenses incurred in attending Board meetings, Committee meetings, and relevant educational seminars. The Trustees also may be compensated for attendance at special Board and/or Committee meetings from time to time. The Board Chairman receives an additional annual retainer of $50,000 as well as a single $5,000 fee each quarter for his attendance at the Committee meetings. The chairpersons of the Audit Committee and the Investment Committee each receive an additional annual retainer of $25,000 and the Chairman of the Nominating and Governance Committee receives an additional annual retainer of $10,000. These expenses are allocated on a prorated basis to each Fund of the Trust according to its respective net assets.

3. Security Valuation and Fair Value Measurements

Investments are valued at the close of the New York Stock Exchange (the “Exchange”), normally 4:00 p.m. Eastern Time, 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 are normally are valued on the basis of prices provided by an independent pricing service and may take into account appropriate factors such as institution-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The prices of debt securities may be determined using quotes obtained from brokers.

Investments in open-end mutual funds are valued at the closing 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.

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 Funds. 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 margin disclosed on the Statements of Assets and Liabilities.

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

Valuation Inputs

Various inputs may be used to determine the fair 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.

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

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.

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.

The Funds’ investments are summarized by level based on the inputs used to determine their values. As of February 28, 2017, the investments were classified as described below:

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 six months ended February 28, 2017, there were no transfers between levels.

4. Securities and Other Investments

American Depositary Receipts (“ADRs”)

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 a Fund’s possible inability to convert immediately into U.S.

28

currency proceeds realized upon the sale of portfolio securities of the affected foreign companies. In addition, the Funds 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 Funds to the same benefits and rights as ownership of a sponsored depositary receipt or the underlying security.

Common Stock

Common stock generally takes the form of shares in a corporation which represent an ownership interest. It ranks below preferred stock and debt securities in claims for dividends and for assets of the company in a liquidation or bankruptcy. The value of a company’s common stock may fall as a result of factors directly relating to that company, such as decisions made by its management or decreased demand for the company’s products or services. A stock’s value may also decline because of factors affecting not just the company, but also companies in the same industry or sector. The price of a company’s stock may also be affected by changes in financial markets that are relatively unrelated to the company, such as changes in interest rates, currency exchange rates or industry regulation. Companies that elect to pay dividends on their common stock generally only do so after they invest in their own business and make required payments to bondholders and on other debt and preferred stock. Therefore, the value of a company’s common stock will usually be more volatile than its bonds, other debt and preferred stock. Common stock may be exchange-traded or over-the-counter (“OTC”). OTC stock may be less liquid than exchange-traded stock.

Preferred Stock

A preferred stock blends the characteristics of a bond and common stock. It can offer the higher yield of a bond and has priority over common stock in equity ownership, but does not have the seniority of a bond and its participation in the issuer’s growth may be limited. Preferred stock generally has preference over common stock in the receipt of dividends and in any residual assets after payment to creditors should the issuer be dissolved. Although the dividend is set at a fixed or variable rate, in some circumstances it can be changed or omitted by the issuer. Preferred stocks are subject to the risks associated with other types of equity securities, as well as additional risks, such as credit risk, interest rate risk, potentially greater volatility and risks related to deferral, non-cumulative dividends, subordination, liquidity, limited voting rights, and special redemption rights.

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.

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.

5. Financial Derivative Instruments

The Funds may utilize derivative instruments to manage liquidity. When considering the Funds’ use of derivatives, it is important to note that the Funds do not use derivatives for the purpose of creating financial leverage.

Futures Contracts

Futures contracts are contracts to buy or sell a standard quantity of securities at a specified price on a future date. 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 Funds are 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. A 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 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.

For the six months ended February 28, 2017, the Funds entered into future contracts primarily for 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 each quarter end.

Average Futures Contracts Outstanding

6. Principal Risks

Investing in the Funds may involve certain risks including, but not limited to, those described below:

Credit Risk

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

Dividend Risk

An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks.

Foreign Investing Risk

Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing and financial reporting standards, (5) increased price volatility, (6) less government regulation and supervision of foreign stock exchanges, brokers and listed companies; and (7) delays in transaction settlement in some foreign markets.

Futures Contracts Risk

Futures contracts are derivative instruments where one party pays a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract).

Liquidity Risk

The Zebra Small Cap Equity Fund is susceptible to the risk that certain small cap equity investments held by the Fund may have limited marketability or be subject to restrictions on sale, and may be difficult or impossible to purchase or sell at favorable times or prices. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund. For example, the Fund may be forced to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Judgment plays a greater role in pricing illiquid investments than in investments with more active markets

Market Risk

Since the financial crisis that started in 2008, the U.S. and many foreign economies continue to experience its after-effects, which have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

31

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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

Other Investment Companies Risk

The Funds may invest in shares of other registered investment companies, including money market funds. To the extent that a Fund invests in shares of other registered investment companies, you will indirectly bear fees and expenses charged by those investment companies in addition to the Fund’s direct fees and expenses and will be subject to the risks associated with investments in those funds. For example, money market funds are subject to interest rate risk, credit risk, and market risk.

Securities Lending Risk

To the extent a Fund lends its securities, it may be subject to the following risks. Borrowers of the Fund’s securities typically provide collateral in the form of cash that is reinvested in securities. The securities in which the collateral is invested may not perform sufficiently to cover the return collateral payments owed to borrowers. In addition, delays may occur in the recovery of securities from borrowers, which could interfere with a Fund’s ability to vote proxies or to settle transactions and there is the risk of possible loss of rights in the collateral should the borrower fail financially.

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 February 28, 2017.

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 recorded tax liabilities in the accompanying financial statements. The tax years for the periods ended August 31, 2013, 2014, 2015, and 2016 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.

33

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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.

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 tax character of distributions paid were as follows:

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

As of February 28, 2017, the components of distributable earnings (deficit) on a tax basis were as follows:

	The London Company			Zebra Small Cap
	Income Equity Fund			Equity Fund
Cost basis of investments for federal income tax purposes	$	1,016,057,300		$	33,602,425
Unrealized appreciation		193,765,836			4,878,625
Unrealized depreciation		(20,999,494	)		(1,718,297	)
Net unrealized appreciation (depreciation)		172,766,342			3,160,328
Undistributed ordinary income		2,162,643			989,282
Undistributed long-term capital gains		—			955,318

Other temporary differences		—			—
Distributable earnings (deficits)	$	155,193,975		$	5,104,928

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 (depreciation) are attributable primarily to the tax deferral of losses from wash sales, the realization for tax purposes of unrealized gains (losses) on certain derivative instruments and the reclassification of income from real estate investment securities.

Due to inherent differences in the recognition of income, expenses and realized gains (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.

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 February 28, 2017, The London Company Income Equity Fund has $1,358,719 of short-term and $18,376,291 of long-term post RIC MOD capital loss carryforward .

Zebra Small Cap Equity	Lending		356,775		2,296,684		2,570,109		83,350		N/A

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 subject to standard settlement periods. This 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

35

American Beacon Funds^SM

Notes to Financial Statements

February 28, 2017 (Unaudited)

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 February 28, 2017, the value of outstanding securities on loan and the value of collateral was as follows :

Fair Value of			Cash Collateral
Securities on Loan	Non-Cash Collateral		Posted by Borrower
$81,430	$	—	$	83,350

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.
