ECONOMIC OVERVIEW
JUNE 30, 2007 (Unaudited)

     Annualized Gross Domestic Product ("GDP") growth came in at an anemic 0.7%
during the first quarter of 2007, the lowest rate of growth in four years.
Inventory drawdowns, a widening trade deficit and an ongoing slump in the
housing market were the main contributors to the slowdown. GDP growth in the
second quarter recovered to an estimated 3.4% annualized rate as consumer
spending held strong and business investment rebounded. The labor market
remained a bright spot for the economy. Higher wages enabled consumers to keep
spending despite increasing energy prices and declining home values. Payroll
gains averaged 148,000 per month during the second quarter of 2007 and the
unemployment rate remained near a six-year low at 4.5% in June.

     The Federal Open Market Committee ("Fed") left rates unchanged at 5.25% at
both the May and June meetings. This marked eight consecutive meetings with no
movement from the Fed. In its June statement, the Fed acknowledged that the
economy was expected to expand at a moderate pace and that core inflation
measures had improved modestly. However, Fed officials remained concerned about
the high level of resource utilization and stated that "a sustained moderation
in inflation pressures has yet to be convincingly demonstrated." Thus the Fed's
inflation bias remained in place after the June meeting.

     Though economic growth recovered in the second quarter and the Fed has been
unremitting in its commitment to contain inflation, the market is fearful that
subprime mortgage difficulties could spill over into the broader economy. As
such, the Fed continues to maintain ample flexibility by stating that "future
policy adjustments will depend on the evolution of the outlook for both
inflation and economic growth."

PERFORMANCE OVERVIEW
AMERICAN BEACON MONEY MARKET FUND(SM)
JUNE 30, 2007 (Unaudited)

     The Money Market Fund will maintain the strategy of purchasing high quality
commercial paper maturing in 3 months or less and 3-month London Interbank
Offered Rate (LIBOR) based variable rate securities until it becomes apparent
that the Fed is on the verge of lowering interest rates. In addition, we remain
conservative on credit risk given the volatile credit spread environment and
effects of the subprime mortgage difficulties.

     For the six months ended June 30, 2007, the total return of the Cash
Management Class of the American Beacon Money Market Fund was 2.62%. The Fund
outperformed the Lipper Institutional Money Market Average return of 2.47% by 15
basis points (0.15%). Lipper Inc. ranked the Cash Management Class of the Fund
17th among 350, 20th among 298, and 18th among 252 Institutional Money Market
Funds for the one-year, three-year and five-year periods ended June 30, 2007,
respectively. The Lipper Institutional Money Market Average is calculated by
taking an arithmetic average of the returns of the mutual funds in the Lipper
Institutional Money Market Funds category. Lipper is an independent mutual fund
research and ranking service that ranks mutual funds in various categories by
making comparative calculations using total returns.

1.   Performance shown is historical and may not be indicative of future
     returns. Investment returns will vary, and shares may be worth more or less
     at redemption than at original purchase. An investment in this Fund is
     neither insured nor guaranteed by the Federal Deposit Insurance Corporation
     or any other government agency. Although the Fund seeks to preserve the
     value of an investment at $1.00 per share it is possible to lose money by
     investing in the Fund. Fund performance in the table above does not reflect
     the deduction of taxes a shareholder would pay on distributions or the
     redemption of shares.

2.   Fund performance for the five and ten-year periods represent the total
     returns achieved by the Institutional Class from 7/1/97 to 12/1/01, the
     inception date of the Cash Management Class, and the returns of the Cash
     Management Class thereafter. Expenses of the Cash Management Class are
     lower than those of the Institutional Class. Therefore, total returns shown
     are lower than they would have been had the Cash Management Class been in
     place since 7/1/97. A portion of the fees charged to the Cash Management
     Class of the Fund has been waived. Performance prior to waiving fees was
     lower than the actual returns shown.

3.   A portion of the fees charged to the Institutional Class of the Fund has
     been waived since 2006. Performance prior to waiving fees was lower than
     the actual returns shown for periods since 2006.

4.   Fund performance represents the total returns achieved by the Institutional
     Class from 7/1/97 to 12/1/01, the total returns achieved by the Cash
     Management Class from 12/1/01 up to 4/2/07, the inception date of the BBH
     Comset Class, and the returns of the BBH Comset Class thereafter. Expenses
     of the BBH Comset Class are lower than those of the Institutional and Cash
     Management Classes through 12/31/03. Therefore, total returns shown through
     12/31/03 are lower than they would have been had the BBH Comset Class been
     in place during that period. Expenses of the BBH Comset Class have been the
     same as those of the Cash Management Class since 1/1/04.

5.   The total annual Fund operating expense ratio set forth in the most recent
     Fund prospectus for the Cash Management, Institutional, PlanAhead and the
     BBH Comset Class shares was 0.20%, 0.23%, 0.49% and 0.19%, respectively.
     After expense reimbursement, the net expense ratio set forth in the most
     recent Fund prospectus for the Cash Management, Institutional and BBH
     Comset Class shares was 0.15%, 0.18% and 0.15%, 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.

PERFORMANCE OVERVIEW
AMERICAN BEACON MONEY MARKET FUND(SM)
JUNE 30, 2007 (Unaudited)

FUND EXPENSE EXAMPLE

     As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs and (2) ongoing costs, including management fees, administrative service
fees, and other Fund expenses. The examples below are intended to help you
understand the ongoing cost (in dollars) of investing in the Fund and to compare
these costs with the ongoing costs of investing in other mutual funds. The
examples are based on an investment of $1,000 invested at the beginning of the
period and held for the entire period from January 1, 2007 through June 30,
2007.

ACTUAL EXPENSES

     The "Actual" lines of the table provide information about actual account
values and actual expenses. You may use the information in these lines, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the "Actual" line under the heading "Expenses Paid During Period" for the
applicable Class to estimate the expenses you paid on your account during this
period. Shareholders of the PlanAhead Class that invest in the Fund through an
IRA may be subject to a custodial IRA fee of $12 that is typically deducted each
December. If your account was subject to a custodial IRA fee during the period,
your costs would have been $12 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 PlanAhead Class that invest in the Fund through an IRA may be subject to
a custodial IRA fee of $12 that is typically deducted each  December.  If your
account was subject to a custodial IRA fee during the period, your costs would
have been $12 higher.

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

     days in the most recent fiscal half-year (90) by days in the year (365) to
     reflect the half-year period.

PERFORMANCE OVERVIEW
AMERICAN BEACON U.S. GOVERNMENT MONEY MARKET FUND(SM)
JUNE 30, 2007 (Unaudited)

     The U.S. Government Money Market Fund will maintain the strategy of
primarily transacting overnight repurchase agreements until it becomes more
apparent that the Fed is on the verge of lowering interest rates. We remain
conservative on credit risk given the volatile credit spread environment and
effects of the subprime mortgage difficulties.

     For the year ended June 30, 2007, the total return of the Cash Management
Class of the American Beacon U.S. Government Money Market Fund was 2.59%. The
Fund outperformed the Lipper Institutional U.S. Government Money Market Average
return of 2.46% by 13 basis points (0.13%). Lipper Inc. ranked the Cash
Management Class of the Fund 8th among 148, 8th among 106 and 7th among 66
Institutional U.S. Government Money Market Funds for the one-year, five-year and
ten-year periods ended June 30, 2007, respectively. The Lipper Institutional

1    Performance shown is historical and may not be indicative of future
     returns. Investment returns will vary, and shares may be worth more or less
     at redemption than at original purchase. An investment in this Fund is
     neither insured nor guaranteed by the Federal Deposit Insurance Corporation
     or any other government agency. Although the Fund seeks to preserve the
     value of an investment at $1.00 per share it is possible to lose money by
     investing in the Fund. Fund performance in the table above does not reflect
     the deduction of taxes a shareholder would pay on distributions or the
     redemption of shares.

2    Prior to December 1, 2001, the Cash Management Class of the Fund was known
     as the Institutional Class. A portion of the fees charged to the Cash
     Management Class of the Fund has been waived since 2002. Performance prior
     to waiving fees was lower than actual returns shown for periods since 2002.

3    A portion of the fees charged to the PlanAhead Class of the Fund has been
     waived since 2003. Performance prior to waiving fees was lower than the
     actual returns shown for periods since 2003.

4    The total annual Fund operating expense ratio set forth in the most recent
     Fund prospectus for the Cash Management and the PlanAhead Class shares was
     0.64% and 1.02%, respectively. After expense reimbursement, the net expense
     ratio set forth in the most recent Fund prospectus for the Cash Management,
     Institutional and BBH Comset Class shares was 0.15% and 0.63%,
     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.

FUND EXPENSE EXAMPLE

     As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs and (2) ongoing costs, including management fees, administrative service
fees, and other Fund expenses. The examples below are intended to help you
understand the ongoing cost (in dollars) of investing in the Fund and to compare
these costs with the ongoing costs of investing in other mutual funds. The
examples are based on an investment of $1,000 invested at the beginning of the
period and held for the entire period from January 1, 2007 through June 30,
2007.

ACTUAL EXPENSES

     The "Actual" lines of the table provide information about actual account
values and actual expenses. You may use the information in these lines, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the "Actual" line under the heading "Expenses Paid During Period" for the
applicable Class to estimate the expenses you paid on your account during this
period. Shareholders of the PlanAhead Class that invest in the Fund through an
IRA may be subject to a custodial IRA fee of $12 that is typically deducted each
December. If your account was subject to a custodial IRA fee during the period,
your costs would have been $12 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 PlanAhead Class that invest in the Fund through an IRA may be subject to
a custodial IRA fee of $12 that is typically deducted each December. If your
account was subject to a custodial IRA fee during the period, your costs would
have been $12 higher.

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

*    Expenses are equal to the Fund's annualized expense ratios for the
     six-month period of 0.19% and 0.65% for the Cash Management and PlanAhead
     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.

AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2007 (UNAUDITED)(IN THOUSANDS)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     American Beacon Funds (the "Trust") is organized as a Massachusetts
business trust and is registered under the Investment Company Act of 1940 (the
"Act"), as amended, as a diversified, no-load, open-end management investment
company with separate series. The following series are included in this report:
American Beacon Money Market and American Beacon U.S. Government Money Market
Funds (each a "Fund" and collectively, the "Funds").

     The BBH Comset Class of the Money Market Fund commenced operations on April
2, 2007. The Platinum Class of the Funds was fully liquidated effective May 31,
2007.

     Each Fund invests all of its investable assets in the corresponding
portfolio of the American Beacon Master Trust, an open-end diversified
management investment company, as follows:


                                                                 
AMERICAN BEACON:                  (ARROW) invests assets in (ARROW) AMERICAN BEACON MASTER TRUST:
Money Market Fund                                                   Money Market Portfolio
U.S. Government Money Market Fund                                   U.S. Government Money Market Portfolio


     Each Fund has the same investment objectives as its corresponding American
Beacon Master Trust Portfolio. The value of such investment reflects each Fund's
proportionate interest in the net assets of the corresponding portfolio (5.5%
and 2.8% at June 30, 2007 of the American Beacon Master Trust Money Market and
U.S. Government Money Market Portfolios, respectively) (each a "Portfolio" and
collectively the "Portfolios"). The financial statements of the Portfolios are
included elsewhere in this report and should be read in conjunction with the
Funds' financial statements.

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

     The following is a summary of the significant accounting policies followed
by the Funds.

Class Disclosure

     Each Fund has multiple classes of shares designed to meet the needs of
different groups of investors. Please note that not all Funds offer all classes.
The following table sets forth the differences amongst the classes:



CLASS:                               OFFERED TO:                 SERVICE AND DISTRIBUTION FEES:

                        investment of at least $10 million
                        in BBH ComSet(SM) who meet the
                        eligibility requirements established
                        by Brown Brothers Harriman & Co.


Valuation of Investments

     The Funds record their investment in the Portfolios at fair value.

Portfolios' Notes to Financial Statements, which are included elsewhere in this
report.

Investment Income and Dividends to Shareholders

     Each Fund records its share of net investment income (loss) and realized
gain (loss) in the Portfolio each day. All net investment income (loss) and
realized gain (loss) of each Portfolio are allocated pro rata among the
corresponding Fund and other investors in each Portfolio at the time of such
determination. The Funds generally declare dividends daily from net investment
income and net short-term capital gain, if any, payable monthly.

     Dividends to shareholders are determined in accordance with federal income
tax principles that may treat certain transactions differently than U.S.
generally accepted accounting principles.

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

Recently Issued Accounting Pronouncements

     On July 13, 2006, the Financial Accounting Standards Board ("FASB")
released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes"
("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing each Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. The Funds
adopted the provisions of FIN 48 effective January 1, 2007. Tax positions taken
by the Funds have been deemed to meet the more likely than not threshold, and
therefore, there have been no adjustments to the Funds' net asset value per
share.

     In September 2006, the FASB issued Statement on Financial Accounting
Standards No. 157, "Fair Value Measurements" ("FAS 157"). This standard
clarifies the definition of fair value for financial reporting, establishes a
framework for measuring fair value and requires additional disclosures about the
use of fair value measurements. FAS 157 is effective for financial statements
issued for fiscal years beginning after November 15, 2007 and interim periods
within those fiscal years. The Manager is evaluating the impact of FAS 157;
however, it is not expected to have a material impact on the Funds' net assets
or results of operations.

Other

     Under the Trust's organizational documents, its officers and directors 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.

2. TRANSACTIONS WITH AFFILIATES

Administrative Services Agreement

     As compensation for providing administrative services to the Funds, the
Manager receives an annualized fee of 0.10% of the average daily net assets of
each of the Institutional and PlanAhead Classes of the Funds, 0.08% of the
average daily net assets of the BBH Class of the Money Market Fund and 0.07% of
the Cash Management Class of the Funds.

Distribution Plan

     The Trust has adopted a "defensive" Distribution Plan (the "Plan") in
accordance with Rule 12b-1 under the Act, pursuant to which no fees may be
charged to the Funds for distribution purposes. However, the Plan authorizes the
fees received by the Manager to be used for distribution purposes. Under this
plan, the Trust does not intend to compensate the Manager or any other party,
either directly or indirectly, for the distribution of Trust shares.

Service Agreement

     The Manager and the Trust entered into a Service Agreement which obligates
the Manager to oversee additional shareholder servicing of the PlanAhead Class.
As compensation for performing the duties required under the Service Agreement,
the Manager receives 0.25% based on the daily net assets of the PlanAhead Class.

Reimbursement and Waiver of Expenses

     The Manager contractually agreed to reimburse the following Funds for
distribution and other expenses through February 29, 2008 to the extent total
annual fund operating expenses exceed the following amounts:



FUND                                     CLASS        EXPENSE CAP    AMOUNT
- ----                                ---------------   -----------   -------
                                                           
Money Market Fund                   Institutional       0.18%**     $50,430
Money Market Fund                   Cash Management     0.15%       163,573
U.S. Government Money Market Fund   Cash Management     0.15%*      1,290
U.S. Government Money Market Fund   PlanAhead           0.65%       1,312


*    Prior to March 1, 2007, the expense cap was 0.19%.

**   Prior to March 1, 2007, fees were voluntarily waived by the Manager to
     arrive at expense cap.

     The Manager voluntarily agreed to reimburse the BBH ComSet Class of the
Money Market Fund for other expenses through February 29, 2008 to the extent
total annual fund operating expenses exceeded 0.15%. The Manager reimbursed
expenses totaling $6,494 to the BBH ComSet Class of the Money Market Fund during
the six months ended June 30, 2007.

Expense Reimbursement Plan

     The Funds have adopted an Expense Reimbursement Plan whereby the Manager
may seek recoupment of fees waived or expenses reimbursed for a period of up to
three years. However, recoupment will occur only if the Class' average net
assets have grown or expenses have declined sufficiently to allow recoupment
without causing its expense ratio to exceed the previously agreed upon expense
limit. The following waived fees or reimbursed expenses are subject to potential
recovery expiring in:

*    Excludes waived fees or reimbursed expenses related to the Platinum class,
     which was closed May 14, 2007

     The Funds have not recorded a liability for this potential reimbursement
due to the current assessment that a reimbursement is unlikely.

3. FEDERAL INCOME TAXES

     It is the policy of each of the Funds to comply with the requirements of
Subchapter M of the Internal Revenue Code and to distribute substantially all
net investment income as well as any net realized capital gains on the sale of
investments. Therefore, no federal income tax provision is required.

     Net investment income and net realized gains (losses) may differ for
financial statement and tax purposes because of temporary or permanent
book-to-tax differences. To the extent these differences are permanent,
reclassifications are made to the appropriate equity accounts in the period that
the differences arise. Temporary differences are not reflected in the financial
records.

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

     The tax character of distributions paid for the six months ended June 30,
2007 and the year ended December 31, 2006 were as follows (in thousands):



                                                                   U.S. GOVERNMENT

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

     As of June 30, 2007, the components of distributable earnings on a tax
basis were the same as book. The cost basis of investments for federal income
tax purposes was also the same as the book basis.

     The Funds do not have capital loss carry forwards as of June 30, 2007.

AMERICAN BEACON MASTER TRUST
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     American Beacon Master Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended, as a no load, open-end management
investment company that was organized as a trust under the laws of the
Commonwealth of Massachusetts pursuant to a Declaration of Trust dated as of
November 1, 2004. Prior to November 1, 2004, the Trust was organized as a trust
under the laws of the State of New York. Beneficial interests in the Trust are
divided into separate series, each having distinct investment objectives and
policies. These financial statements relate to the American Beacon Master Money
Market Portfolio and American Beacon Master U.S. Government Money Market
Portfolio (each a "Portfolio" and collectively the "Portfolios"). The objective
of each Portfolio is current income, liquidity and the maintenance of a stable
price of $1.00 per share. The assets of each Portfolio belong only to that
Portfolio, and the liabilities of each Portfolio are borne solely by that
Portfolio and no other.

     American Beacon Advisors, Inc. (the "Manager") is a wholly owned subsidiary
of AMR Corporation and was organized in 1986 to provide business management,
advisory, administrative and asset management consulting services.

     The following is a summary of the significant accounting policies followed
by the Portfolios.

Security Valuation

     Securities of the Portfolios are valued at amortized cost, which
approximates fair value. In the event that a deviation of 1/2 of 1% or more
exists between the $1.00 per share price of the Portfolios, calculated at
amortized cost, and the price per share calculated by reference to market
quotations, or if there is any other deviation that the Trust's Board of
Trustees (the "Board") believes would result in a material dilution to
shareholders or purchasers, the Board will promptly consider the appropriate
action that should be initiated.

Security Transactions and Investment Income

     Security transactions are recorded on the trade date of the security
purchase or sale. Interest income is earned from settlement date, recorded on
the accrual basis, and adjusted, if necessary, for amortization of premiums or
accretion of discounts on investment grade short-term securities and zero coupon
instruments. For financial and tax reporting purposes, realized gains and losses
are determined on the basis of specific lot identification.

Federal Income Taxes

     The Portfolios will be treated as partnerships for federal income tax
purposes. As such, each investor in a Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that each
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of subchapter M of the
Internal Revenue Code.

Repurchase Agreements

     Under the terms of a repurchase agreement, securities are acquired by a
Portfolio from a securities dealer or a bank that are subject to resale at a
later date. Repurchase agreements are fully collateralized by U.S. Treasury or
U.S. Government agency securities and are valued at cost, which approximates
market value. All collateral is held at the custodian bank. The collateral is
monitored daily by the Manager so that the collateral's market value exceeds the
carrying value of the repurchase agreement plus accrued interest.

AMERICAN BEACON MASTER TRUST
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2007 (UNAUDITED)

Use of Estimates

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

Recently Issued Accounting Pronouncements

     On July 13, 2006, the Financial Accounting Standards Board ("FASB")
released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes"
("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing each Portfolio's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. The Portolios
adopted the provisions of FIN 48 effective January 1, 2007. Tax positions taken
by the Portfolios have been deemed to meet the more likely than not threshold,
and therefore, there have been no adjustments to the Portfolios' net asset value
per share.

     In September 2006, the FASB issued Statement on Financial Accounting
Standards No. 157, "Fair Value Measurements" ("FAS 157"). This standard
clarifies the definition of fair value for financial reporting, establishes a
framework for measuring fair value and requires additional disclosures about the
use of fair value measurements. FAS 157 is effective for financial statements
issued for fiscal years beginning after November 15, 2007 and interim periods
within those fiscal years. The Manager is evaluating the impact of FAS 157;
however, it is not expected to have a material impact on the Portfolios' net
assets or results of operations.

Other

     Under the Trust's organizational documents, its officers and directors 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.

2. TRANSACTIONS WITH AFFILIATES

Management Agreement

     The Trust and the Manager are parties to a Management Agreement that
obligates the Manager to provide or oversee the provision of all administrative,
investment advisory and portfolio management services. The Manager serves as the
sole investment advisor to each of the Portfolios. As compensation for
performing the duties required under the Management Agreement, the Manager
receives from the Portfolios 0.10% of the average daily net assets of each of
the Portfolios.

Interfund Lending Program

     Pursuant to an exemptive order by the Securities and Exchange Commission,
the Portfolios, 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 Money
Market Portfolio to lend money to other participating series managed by the
Manager. For the six months ended June 30, 2007, the Money Market Portfolio
earned $8,708 under the credit facility. This amount is included in interest
income on the financial statements.

DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT
AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS
(UNAUDITED)

INTERIM RENEWAL

In prior years, the Board of Trustees ("Board" or "Trustees") typically has
considered the annual renewal of the existing Management Agreements between
American Beacon Advisors, Inc. (the "Manager") and the American Beacon Funds
(the "Trust"), on behalf of the Money Market and U.S. Government Money Market
Funds (each, a "Fund" and collectively, the "Funds"), and between the Manager
and the American Beacon Master Trust, on behalf of the Money Market and U.S.
Government Money Market Portfolios (collectively, the "Portfolios"), at the
Board meeting held in the first quarter of each year. (The term "Funds" is used
throughout this section to refer to both the Funds and the Portfolios.) At the
November 15, 2006 meeting, the Board decided to conduct these annual renewals at
their second quarter meeting each year to enable the Trustees to consider more
year-end data in their deliberations. At the March 8, 2007 Board meeting, the
Board considered renewal of the Management Agreements on an interim basis until
the Board meeting scheduled for the second quarter, at which meeting the Board
would perform a comprehensive review of factors relevant to an annual renewal.

In connection with the interim renewal, the Board, with the assistance of
independent legal counsel, requested and received certain relevant information
from the Manager. Further, the Board took into consideration information
furnished for the Board's review and consideration throughout the year at
regular Board and Investment Committee meetings. The Board considered several
factors at its March 2007 meeting.but did not identify any particular
information that was most relevant to its consideration to renew the Management
Agreement, and each Trustee may have afforded different weight to these factors.
The Board determined that certain factors typically considered in connection
with an annual renewal were not material with respect to an interim renewal.

In determining whether to renew the Management Agreement on an interim basis,
the Trustees considered the best interests of each Fund separately. The
following considerations and conclusions are applicable to all Funds.

Cost of Services. With respect to the Management Agreement, the Board noted that
the Manager proposed to continue most of the expense waivers and reimbursements
that were in place for each applicable Fund's 2006 fiscal year as well as
implement additional waivers and/or reimbursements.

Nature, Extent and Quality of Services. With respect to the renewal of the
Management Agreement, the Trustees considered that the Manager continues to
provide high-quality services to each Fund at a low cost to investors and
provides a comprehensive compliance program for each Fund. Based on this
information, the Board concluded that the nature, extent and quality of the
management and advisory services provided by the Manager were appropriate for
each Fund and, thus, supported a decision to renew the Management Agreement on
an interim basis.

Investment Performance. The Board considered the performance reports and
discussions with management at Board and Committee meetings throughout the year.

In considering the renewal of the Management Agreement with the Manager for the
Funds, the Trustees considered that 1) each Fund outperformed its respective
benchmark index for the 2006 calendar year, and 2) the fee rate schedules for
the Manager had not changed since the last contract renewal.

Based on, among others, considerations and those noted above with respect to all
Funds, the Trustees determined that the Funds and their shareholders would
benefit from the Manager's continued management of the Funds until the next
regular Board meeting and approved the renewal of the Agreement with respect to
each of the Funds on an interim basis until the next regular Board meeting.

ANNUAL RENEWAL

At its May 25, 2007 meeting, the Board considered the renewal of the Management
Agreements. In preparation for the Board's consideration to renew the
Agreements, the Board and its Investment Committee undertook steps to gather and
consider information furnished by the Manager and Lipper, Inc. ("Lipper"). The
Board, with the assistance of independent legal counsel, requested and received
certain relevant information from the Manager.

In addition, the Board's Investment Committee worked with Lipper to obtain
relevant comparative information regarding the performance, fees and expenses of
the Funds. The Investment Committee held a separate meeting on May 4, 2007 to
consider the information provided by Lipper. Further, the Board took into
consideration information furnished for the Board's review and consideration
throughout the year at regular Board and Investment Committee meetings, as well
as information specifically prepared in connection with the renewal process.

The Trustees considered, among other materials, responses by the Manager to
inquiries requesting:

     -    a description of any significant changes (actual or anticipated) to
          principal activities, personnel, services provided to the Funds, or
          any other area, including how these changes might affect the Funds;

     -    a copy of the Manager's SEC Form ADV registration statement;

     -    a summary of any material past, pending or anticipated litigation or
          regulatory proceedings involving the Manager or its personnel,
          including the results of any recent regulatory examination or
          independent audit;

     -    a comparison of performance of each Fund to comparable investment
          companies and appropriate indices, including comments on the relative
          performance of each Fund versus the respective peer group average;

     -    a profit/loss analysis of the Manager and any actual or anticipated
          economies of scale in relation to the services it provides to each
          Fund;

     -    an analysis of compensation, including a comparison with fees charged
          to other clients for which similar services are provided, any proposed
          changes to the fee schedule and the effect of any fee waivers;

     -    an evaluation of other benefits to the Manager or Funds as a result of
          their relationship, if any;

     -    confirmation that the Manager's financial condition does not raise
          concerns that the Manager would be unable to continue providing the
          same scope and quality of services to the Funds;

     -    a description of the scope of portfolio management services provided
          to the Funds and other clients, including other registered investment
          companies, whether such services differ, and any advantages or
          disadvantages that might accrue to the Funds due to the manager's
          involvement in other activities;

     -    a description of the personnel who are assigned primary responsibility
          for managing the Funds, including any changes during the past year and
          a discussion of the adequacy of current and projected staffing levels
          to service the Funds;

     -    a description of the basis upon which portfolio managers are
          compensated, including any "incentive" arrangements;

     -    a discussion regarding the Manager's participation in "soft dollar"
          arrangements, if any, or other brokerage allocation policies with
          respect to Fund transactions, including the Manager's methodology for
          obtaining the most favorable execution and the use of any affiliated
          broker-dealers;

     -    a description of any actual or potential conflicts of interest
          anticipated in managing Fund assets;

     -    a description of trade allocation procedures among accounts managed by
          the Manager;

(UNAUDITED)

     -    a summary of any material changes to the Manager's compliance program
          with regard to federal, state, corporate and Fund requirements and a
          certification to the reasonable design of the compliance program;

     -    a discussion of any material compliance problems and remedial actions;

     -    information regarding the Manager's code of ethics, insider trading
          policy and disaster recovery plan, including a description of any
          material changes thereto;

     -    a description of the Manager's affiliation with any broker-dealer;

     -    a discussion of any anticipated change in the Manager's controlling
          persons;

     -    verification of the Manager's insurance coverage with regards to the
          services provided to the Funds.

     -    a comparison of advisory fees and expense ratios for comparable mutual
          funds;

     -    an analysis of any material complaints received from Fund
          shareholders;

     -    a description of any revenue sharing activities with respect to the
          Funds;

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

     -    a discussion of whether the Manager receives, with respect to the
          Funds, other compensation; and

     -    a description of how expenses that are not readily identifiable to a
          particular Fund are allocated.

The Board also obtained an analysis provided by Lipper that compared: (i)
investment performance of each Fund versus comparable investment companies and
appropriate indices; (ii) total Fund expenses of each Fund versus comparable
mutual funds, and (iii) each Fund's investment advisory fees versus comparable
mutual funds. For each Fund, the class used for comparative purposes was the
class with the longest performance history, which in most cases is the
Institutional Class. References below to each Fund's Lipper peer group are to
the group of comparable mutual funds included in the analysis provided by
Lipper.

The Trustees also received a memorandum from their legal counsel detailing the
Board's responsibilities pertaining to the renewal of the Management Agreements.
This memorandum explained the regulatory requirements surrounding the Trustees'
process for evaluating investment advisors and the terms of the contracts.

Provided below is an overview of the primary factors the Board considered at its
May 25, 2007 meeting. The Board did not identify any particular information that
was most relevant to its consideration to renew the Management and Investment
Advisory Agreements, and each Trustee may have afforded different weight to the
various factors.

CONSIDERATIONS WITH RESPECT TO ALL FUNDS

In determining whether to approve the continuance of the Management Agreements,
the Trustees considered the best interests of each Fund separately. In addition,
while the Management Agreements for all of the Funds were considered at the same
Board meeting, the Board considered each Fund's investment management
relationships separately. In each instance, the Board considered, among other
things, the following factors: (1) the nature and quality of the services
provided; (2) the investment performance of the Fund and the investment advisor;
(3) the Manager's cost for providing the services and the profitability of the
advisory business to the Manager; (4) the extent to which economies of scale
have been taken into account in setting the fee schedule; (5) whether fee levels
reflect these economies of scale for the benefit of Fund investors; (6)
comparisons of services and fees with contracts entered into by the Manager with
other clients (such as pension funds and other institutional funds); and (7) any
other benefits derived or anticipated to be derived by the Manager from its
relationship with a Fund. The Trustees posed questions to various management
personnel of the Manager regarding certain key aspects of the material submitted
in support of the renewal.


                                       37



DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT
AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS - CONTINUED
(UNAUDITED)

Nature, Extent and Quality of Services. With respect to the renewal of each
Management Agreement the Board considered: the background and experience of key
investment personnel and the Manager's ability to retain them; the Manager's
disciplined investment approach and goal to provide consistent above average
long-term performance at a low cost; the Manager's continuing efforts to add new
series and share classes to enhance the Funds' product line; the Manager's
record in building improved compliance, control and credit functions that reduce
risks to the Funds; the addition of personnel to manage the Funds, promote sales
and improve services, including the addition of a separate new information
technology department at the Manager; and the high rankings received by the
Funds in service surveys.

Based on the foregoing information, the Board concluded that the nature, extent
and quality of the management services provided by the Manager were appropriate
for each Fund and, thus, supported a decision to renew each Management
Agreement.

Investment Performance. The Board evaluated the comparative information provided
by Lipper and the Manager regarding each Fund's investment performance relative
to its benchmark index(es) and peer group. With respect to Lipper data, the
Board considered the information provided by Lipper regarding its independent
peer selection methodology to select all peer groups and universes. The Board
also considered the performance reports and discussions with management at Board
and Committee meetings throughout the year. A discussion regarding the Board's
considerations with respect to each Fund's performance appears below under
"Additional Considerations and Conclusions with Respect to Each Fund."

Cost of Services and Profits Realized. In analyzing the cost of services and
profitability of the Manager by Fund, the Board considered the revenues earned
and the expenses incurred by the Manager. The profitability levels were noted at
both an individual Fund level and at an aggregate level for all Funds. The Board
also considered that the Management Agreement for the Trust stipulates that to
the extent that a Fund invests all of its investable assets in another
registered investment company, the Fund will not pay the Manager a management
fee. Each Fund operates under a master-feeder structure whereby each Fund
invests all of its assets in a corresponding portfolio of the American Beacon
Master Trust. As such, the Manager receives a management fee from the master
portfolio. The Board also considered the Manager's advisory fees for services
provided by the Manager to institutional separate accounts with similar
investment strategies. Although the Board noted that, in certain cases, the fee
rates paid by other clients is lower than the fee rates paid by the Funds, the
difference reflects the greater level of responsibility and regulatory
requirements associated with managing the Funds.

The Board also noted that the Manager proposed to continue the expense waivers
and reimbursements for certain Funds and Classes that were in place during the
last fiscal year. The Board considered that the Manager receives service and
administrative fees to compensate the Manager for providing administrative
services to the Funds and to compensate third-party administrators and
broker-dealers for services to Fund shareholders. The Board also noted that the
non-Institutional Classes of the Funds maintain higher expense ratios in order
to compensate third party distributors but the net fee to the Manager is
generally the same for all Classes.

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

Economies of Scale. In considering the reasonableness of the management fees,
the Board considered whether economies of scale will be realized as the Funds
grow and whether fee levels reflect these economies of scale for the benefit of
Fund shareholders. The Board noted that the Funds have experienced substantial
recent


                                       38



DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT
AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS - CONTINUED
(UNAUDITED)

asset growth. With respect to the Funds, the Board noted that, although the fee
schedules for these Funds do not have breakpoints, the effective advisory fee
rates are low by industry standards and the performance of these Funds has been
highly competitive and, in many cases, among the top performers among similar
funds.

The Board also considered the Manager's representations that its costs have
increased due primarily to greater service provider and regulatory costs. The
Manager also represented that it anticipates further economies of scale would be
largely offset by higher costs of adding and retaining qualified personnel,
improving technology and increasing demands on its advisory business.

Based on the foregoing information, the Board concluded that the Manager fee
schedule provides for a reasonable sharing of benefits from any economies of
scale with each Fund.

Benefits Derived from the Relationship with the Funds. The Board considered the
"fall-out" or ancillary benefits that accrue to the Manager as a result of the
advisory relationships with the Funds, including greater exposure in the
marketplace with respect to the Manager's investment process and expanding the
level of assets under management by the Manager. The Board also considered that
the Funds permit institutional investors access to such investments at a more
favorable cost and that the Manager's relationship with the Funds continues to
be a significant factor in attracting separate account assets for the Manager.
In addition, the Board noted that the Manager provides services to the Trust at
a relatively low cost.

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

ADDITIONAL CONSIDERATIONS AND CONCLUSIONS WITH RESPECT TO EACH FUND

The performance of each Fund was compared to the respective Lipper Average,
which includes all comparable funds in the Lipper category, and the Lipper
Index, which includes the 30 largest funds in the Lipper category. References to
the Lipper expense group below are to the group of comparable mutual funds
included in the analysis provided to the Trustees by Lipper. All performance
comparisons are for periods ended March 31, 2007, unless otherwise noted.

ADDITIONAL CONSIDERATIONS AND CONCLUSIONS WITH RESPECT TO THE MONEY MARKET FUND

In considering the renewal of the Management Agreement with the Fund, the
Trustees considered the following additional factors: (1) the Money Market Fund
underperformed the Lipper Index for all reported periods except the one-year,
but outperformed the Lipper Average for all reported periods; (2) the actual
management fee and total expense ratio of the Money Market Fund were both lower
than its Lipper expense group median; (3) the Manager is subject to a risk of
financial responsibility should the Fund be unable to maintain a stable $1.00
per share net asset value; (4) the Manager's explanation that fee schedule
"breakpoints" were not warranted due to, among other factors, the low base
management fee charged to the Fund; and (5) the Manager has contractually agreed
to waive fees and/or reimburse Fund expenses to the extent necessary to maintain
a competitive total expense ratio for the Institutional and Cash Management
Classes of the Money Market Fund.

Based on these considerations and those noted above with respect to all Funds,
the Trustees (1) concluded that the fees paid to the Manager under the
Management Agreement are fair and reasonable, (2) determined that the Fund and
its shareholders would benefit from the Manager's continued management of the
Fund and (3) approved the renewal of the Management Agreement with respect to
the Fund.

ADDITIONAL CONSIDERATIONS AND CONCLUSIONS WITH RESPECT TO THE U.S. GOVERNMENT
MONEY MARKET FUND

In considering the renewal of the Management Agreement with respect to the Fund,
the Trustees considered the following additional factors: (1) the Cash
Management Class of the U.S. Government Money Market Fund ("Cash Management
Class") outperformed the Lipper Index and Average for all reported periods; (2)
the actual management fee (including administrative fees) and the total expense
ratio of the Cash Management Class was lower than its Lipper expense group
median; (3) the Manager is subject to a risk of financial responsibility should
the Fund be unable to maintain a stable $1.00 per share net asset value; (4) the
Manager's explanation that fee schedule "breakpoints" were not warranted due to,
among other factors, the low, base management fee charged to the Fund; and (5)
the Manager has contractually agreed to continue to waive fees and/or reimburse
Fund expenses to the extent necessary to maintain a competitive total expense
ratio for all Classes of the U.S. Government Money Market Fund.

Based on these considerations and those noted above with respect to all Funds,
the Trustees (1) concluded that the fees paid to the Manager under the
Management Agreement are fair and reasonable, (2) determined that the Fund and
its shareholders would benefit from the Manager's continued management of the
Fund and (3) approved the renewal of the Management Agreement with respect to
the Fund.
