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 MILEAGE 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 American
Beacon Money Market Mileage Fund -- Mileage Class was 2.39%. The Fund
outperformed the Lipper Money Market Average return of 2.23% by 16 basis points
(0.16%). The Lipper Money Market Average is calculated by taking an arithmetic
average of the returns of the mutual funds in the Lipper 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.

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" line of the table provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the "Actual" line under the heading "Expenses Paid During Period" to estimate
the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     The "Hypothetical" line of the table provides 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.

     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" line of the
table is 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

Hypothetical (5% return before expenses) ....   $1,000.00   $1,021.82     $3.01


*    Expenses are equal to the Fund's annualized expense ratios for the
     six-month period of 0.60% 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 MONEY MARKET MILEAGE FUND
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     The American Beacon Money Market Mileage Fund (the "Fund") 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.

     The Fund invests all of its investable assets in the Money Market Portfolio
of the American Beacon Master Trust (the "Portfolio"), an open-end diversified
management investment company.



AMERICAN BEACON:            (ARROW) invests assets in (ARROW)   AMERICAN BEACON MASTER TRUST:
- ----------------                                                -----------------------------
                                                             
Money Market Mileage Fund                                       Money Market Portfolio


     The Fund has the same investment objectives as the Portfolio, and the value
of such investment reflects the Fund's proportionate interest in the net assets
of the portfolio (0.28% at June 30, 2007). The financial statements of the
Portfolio are included elsewhere in this report and should be read in
conjunction with the Fund's 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 Fund.

Class Disclosure

     The Platinum Class was fully liquidated effective May 31, 2007.



CLASS:           OFFERED TO:                               SERVICE AND DISTRIBUTION FEES:

Mileage Class    Individuals and certain grantor trusts   Distribution Fee-           0.25%

Platinum Class   Investors investing through selected     Administrative Service Fee- 0.65%
                 financial institutions (such as banks    Distribution Fee-           0.25%
                 and broker dealers)


Valuation of Investments

     The Fund records its investment in the Portfolio at fair value. Valuation
of securities by the Portfolio is discussed in Note 1 of the Portfolio's Notes
to Financial Statements, which are included elsewhere in this report.

Investment Income and Dividends to Shareholders

     The 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 the Portfolio are allocated pro rata among the
corresponding Fund and other investors in the Portfolio at the time of such
determination. The Fund generally declares 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.

AMERICAN BEACON MONEY MARKET MILEAGE FUND
NOTES TO FINANCIAL STATEMENTS

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 the 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 Fund
adopted the provisions of FIN 48 effective January 1, 2007. Tax positions taken
by the Fund have been deemed to meet the more likely than not threshold, and
therefore, there have been no adjustments to the Fund's 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 Fund's net assets
or results of operations.

Other

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

2. TRANSACTIONS WITH AFFILIATES

Management Agreement

     The Manager and the Fund entered into a Management Agreement that obligates
the Manager to provide or oversee administrative and management services to the
Fund. As compensation for performing administrative duties required under the
Management Agreement, the Manager receives an annualized fee of 0.10% of the
average daily net assets of the Fund.

Distribution Plan

     The Fund has adopted a Distribution Plan (the "Plan") pursuant to Rule
12b-1 under the Act. Under the Plan, as compensation for distribution
assistance, the Manager receives an annualized fee of 0.25% of the average daily
net assets. 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. In adopting the Plan, the Fund's Board
of Trustees determined that there was a reasonable likelihood that the Plan
would benefit the Fund and the shareholders.

AMERICAN BEACON MONEY MARKET MILEAGE FUND
NOTES TO FINANCIAL STATEMENTS

Expense Reimbursement Plan

     The Fund has 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 contractual
expense limit. For the six months ended June 30, 2007, there are no fees subject
to recoupment.

3. FEDERAL INCOME TAXES

     It is the policy of the Fund 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 during the six months ended June 30,
2007 and fiscal year ended December 31, 2006 were as follows (in thousands):

*    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 Fund does not have capital loss carryforwards 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. 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 (the
"Portfolio"). The objective of the Portfolio is current income, liquidity and
the maintenance of a stable price of $1.00 per share. The assets of the
Portfolio belong only to that Portfolio, and the liabilities of the 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 Portfolio.

Security Valuation

     Securities of the Portfolio 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 Portfolio, 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 Portfolio will be treated as a partnership for federal income tax
purposes. As such, each investor in the Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that the
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 the
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.

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 the 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 Fund
adopted the provisions of FIN 48 effective January 1, 2007. Tax positions taken
by the Fund have been deemed to meet the more likely than not threshold, and
therefore, there have been no adjustments to the Fund's 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 Fund's 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 the Portfolio. As compensation for performing the
duties required under the Management Agreement, the Manager receives from the
Portfolio 0.10% of the average daily net assets of the Portfolio.

Interfund Lending Program

     Pursuant to an exemptive order by the Securities and Exchange Commission,
the Portfolio, 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 FUND AND THE PORTFOLIO
(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 Mileage
Fund (the "Trust"), on behalf of the Money Market Fund (the "Fund"), and between
the Manager and the American Beacon Master Trust, on behalf of the Money Market
Portfolio (the "Portfolio"), at the board meeting held in the first quarter of
each year. (The term "Fund" is used throughout this section to refer to both the
Fund and the Portfolio.) 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.

Cost of Services. With respect to the Management Agreement, the Board noted that
the fee rate schedule for the Manager had not changed since the last contract
renewal.

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 the Fund at a low cost to investors and
provides a comprehensive compliance program for the 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
the 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
Fund, the Trustees considered that 1) the Fund outperformed its benchmark index
for the 2006 calendar year, and 2) the fee rate schedule for the Manager had not
changed since the last contract renewal.

Based on these considerations, among others, the Trustees determined that the
Fund and its shareholders would benefit from the Manager's continued management
of the Fund until the next regular Board meeting and approved the renewal of the
Agreement with respect to the Fund 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.


                                       25



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

In addition, the Board's Investment Committee worked with Lipper to obtain
relevant comparative information regarding the performance, fees and expenses of
the Fund. 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 Fund, or any
          other area, including how these changes might affect the Fund;

          economies of scale in relation to the services it provides to the
          Fund;

          to other clients for which similar services are provided, any proposed

     -    an evaluation of other benefits to the Manager or Fund 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 Fund;

     -    a description of the scope of portfolio management services provided
          to the Fund and other clients, including other registered investment
          companies;

     -    a description of the personnel who are assigned primary responsibility
          for managing the Fund, 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;

     -    an analysis of any material complaints received from Fund

     -    a discussion of any rebate arrangements between the Manager and a
          service provider to the Fund 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
          Fund, 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 the Fund versus comparable investment companies and
appropriate indices; (ii) total Fund expenses of the Fund versus comparable
mutual funds, and (iii) the Fund's investment advisory fees versus comparable
mutual funds. References below to the 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 Agreements, and
each Trustee may have afforded different weight to the various factors.

In determining whether to approve the continuance of the Management Agreements,
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 the 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.

Nature, Extent and Quality of Services. With respect to the renewal of the
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 Fund's product line; the Manager's
record in building improved compliance, control and credit functions that reduce
risks to the Fund; the addition of personnel to manage the Fund, 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 Fund
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 the Fund and, thus, supported a decision to renew the Management Agreement.


                                       27



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

Investment Performance. The Board evaluated the comparative information provided
by Lipper and the Manager regarding the 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.

The performance of the 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, Inc. All performance
comparisons are for periods ended March 31, 2007, unless otherwise noted. The
Board considered that the Fund outperformed both the Lipper Index and Average
for all reported periods.

Based on the foregoing information, the Board concluded that the investment
performance was reasonable.

Cost of Services and Profits Realized. In analyzing the cost of services and
profitability of the Manager, the Board considered the revenues earned and the
expenses incurred by the Manager. The Board also considered that the Management
Agreement for the Trust stipulates that to the extent that the Fund invests all
of its investable assets in another registered investment company, the Fund will
not pay the Manager a management fee. The Fund operates under a master-feeder
structure whereby the 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 strategies. Although the Board noted that, in
certain cases, the fee rates paid by other clients is lower that the fee rates
paid by the Fund, the difference reflects the greater level of responsibility
and regulatory requirements associated with managing the Fund.

The Board considered the following factors: (1) the actual management fee
(including administrative fees) and total expense ratio of the Fund was lower
than its Lipper expense group median; (2) 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; (3) 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.

Based on the foregoing information, the Board concluded that the profitability
levels were reasonable in light of the services performed by the Manager.

Economies of Scale. In considering the reasonableness of the management fees,
the Board considered whether economies of scale will be realized as the Fund
grows and whether fee levels reflect these economies of scale for the benefit of
Fund shareholders. With respect to the Fund, the Board noted that, although the
fee schedule for the Fund does not have breakpoints, the effective advisory fee
rates are low by industry standards and the performance of the Fund has been
competitive.

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 the Fund.

Benefits Derived from the Relationship with the Fund. The Board considered the
"fall-out" or ancillary benefits that accrue to the Manager as a result of the
advisory relationship with the Fund, including greater


                                       28

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 Fund permits institutional investors access to such
investments at a more favorable cost and that the Manager's relationship with
the Fund 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 Fund
appear to be fair and reasonable.

Based on these considerations, 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.
