DOMESTIC MARKET OVERVIEW
June 30, 2007 (Unaudited)

Signs of stress in the fixed income markets brought a cautious end to the first
half of 2007, with U.S. stocks and bonds both slipping. Risk aversion tended to
increase in the second quarter, especially after hopes for an official rate cut
eroded through May. But in contrast to their less discriminating behavior during
the panicky episodes of April 2005 and May 2006, investors focused their dismay
in spring 2007 on specific sectors and instruments rather than on the broad
market. The second quarter did bring a record high for the S&P 500(R) Index, but
the underpinnings of the global liquidity that has been buoying the capital
markets clearly began to creak.

     After peaking in early June, major equity averages explored a lower trading
range and closed the month with modest losses. The S&P 500 retreated 1.7% for
the month, paring its second quarter return to 6.3%, and its first-half gain
back to 7.0%. With mid caps a touch weaker in June, the broader Russell 1000(R)
Index lost 1.9%, trimming its second quarter result to 5.9%. Since the start of
2007, the Russell 1000 retained a 7.2% return. The S&P 400 Index of mid cap
stocks shed 2.2% in June, leaving it with a 5.8% second quarter gain, and a
still healthy 12% advance since the start of 2007.

     Despite expanding caution in the bond world during June, smaller stocks
held in impressively well on the equity side. With an abundance of short sellers
trying to compress the elevated valuations of small caps, prices found ready
support during market disruptions. As a result, the Russell 2000(R) Index
limited its June decline to 1.5% and retained a 4.4% return for the second
quarter. For the first half as a whole, the Russell 2000 gained 6.5%. The S&P
600 Index, also a benchmark for small caps, declined 1.6% in June, but added
5.2% for the second quarter to extend its first-half return to 8.6%.

     With a rise in credit concerns putting financial stocks on the defensive,
growth-oriented benchmarks outpaced value themes in June to establish a more
measurable advantage on a year-to-date basis. The Russell 1000(R) Growth Index
limited its June loss to 1.5%, against a 2.3% drop for the Russell 1000(R) Value
Index. Russell 1000 Growth added 6.9% for the second quarter and gained 8.1% for
the six-month period, while Russell 1000 Value managed only 4.9% for the quarter
and had a 6.2% return from the start of 2007. The gap grew even greater in the
small cap arena, with the Russell 2000(R) Growth Index limiting its June dip to
0.6%, against a 2.3% decline for the Russell 2000(R) Value Index. Russell
2000(R) Growth advanced 6.7% for the second quarter and was ahead 9.3% from the
start of the year, while Russell 2000(R) Value only edged 2.3% higher on the
June quarter and returned 3.8% for the six-month period.

PERFORMANCE OVERVIEW
AMERICAN BEACON S&P 500 INDEX FUND+
JUNE 30, 2007 (UNAUDITED)

     For the six months ended June 30, 2007, the total return of the
Institutional Class of the American Beacon S&P 500 Index Fund was 6.86%,
slightly below the S&P 500 Index return of 6.96% and slightly in excess of the
Lipper S&P 500 Objective Funds Index return of 6.82%.

1.   Performance shown is historical and may not be indicative of future
     returns. Investment returns and principal value will vary, and shares may
     be worth more or less at redemption than at original purchase. Performance
     shown is as of date indicated, and current performance may be lower or
     higher than the performance data quoted. To obtain performance as of the
     most recent month end, please visit www.americanbeaconfunds.com or call
     1-800- 967-9009. Fund performance in the table above does not reflect the
     deduction of taxes a shareholder would pay on distributions or the
     redemption of shares.

2.   Fund performance for the ten-year period represents the total returns
     achieved by the Institutional Class from 6/30/97 to 3/2/98, the inception
     date of the PlanAhead Class, and the returns of the PlanAhead Class since
     its inception. Because the Institutional Class had lower expenses, its
     performance was better than the PlanAhead Class would have realized during
     the same period. A portion of the fees charged to the PlanAhead Class of
     the Fund was waived through 2002. Performance prior to waiving fees was
     lower than the actual returns shown for periods prior to 2002.

3.   The Lipper S&P 500 Objective Funds Index tracks the results of the 30
     largest mutual funds in the Lipper S&P 500 Objective Funds category. Lipper
     is an independent mutual fund research and ranking service. The S&P 500
     Index is a market capitalization weighted index of common stocks publicly
     traded in the U.S. One cannot invest directly in an index.

4.   The total annual Fund operating expense ratios set forth in the most recent
     Fund prospectus for the Institutional and PlanAhead Class shares was 0.14%
     and 0.61%, 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.

     Nine out of ten sectors in the S&P 500 Index (the "Index") had positive
returns for the first six months of 2007. Energy was the top performing sector,
returning 17.2% for the period. Firm product prices continued to boost oil
stocks, but shares in oil service names also remained in steady upward trends.
The Materials sector was the second best performer, gaining 16.7%, led by
Freeport-McMoRan and U.S. Steel. The Telecommunication Services sector tacked on
15.9%, while the Industrials sector was up 11.0% for the six-month period. The
weakest and only sector posting a negative return for the first six months was
the interest-rate sensitive Financials sector. Financials lost 0.8% in the first
half of 2007.

     The best performing security in the Index for the six-month period was
electronics retailer RadioShack with a 97.5% gain. Also impressive were
Medimmune and Amazon.com with gains of 78.9% and 73.4%, respectively. Lexmark
International posted the worst return for the period, losing 32.6%. The next
worst performers were homebuilders Pulte Homes and Lennar Corp. On the back of
the slowdown in new home sales, these stocks lost 32.0% and 29.9%, respectively.

     As of June 30, 2007, the Fund's largest sector weightings were Financials
(20.9% of assets), Information Technology (15.4% of assets), and Health Care
(11.7% of assets), consistent with the top sector weightings in the Index.

     The investment manager continues to utilize a replication strategy,
typically owning all 500 names in the S&P 500 Index in approximately the same
weightings as the Index. Therefore, the Fund is expected to continue to meet its
objective of closely tracking, before expenses, the return of its benchmark, the
S&P 500 Index.

+    The S&P 500 Index Fund is not sponsored, sold or promoted by Standard &
     Poor's, and Standard & Poor's makes no representation regarding the
     advisability of investing in this fund.

2.   The Lipper Small-Cap Core Funds Index tracks the results of the 30 largest
     mutual funds in the Lipper Small-Cap Core Funds category. Lipper is an
     independent mutual fund research and ranking service. The Russell 2000

3.   The total annual Fund operating expense ratio set forth in the most recent

     the expense ratio presented in other sections of this report that are based
     on expenses incurred during the period covered by this report.

     Eight of the 10 sectors in the Russell 2000 Index ("Index") recorded
positive returns for the six-month period. The Materials sector was, by far, the
performance leader, advancing 22.1%, followed by Industrials, up 15.3%, and
Energy, which was up 14.6%. Conversely, Financials and Utilities declined -6.2%
and -4.0%, respectively. The Health Care sector, while posting a gain of 4.4%,
lagged the broad Index return and was the third worst performing sector.

     The strongest performers among individual stocks in the Index included
Rural Cellular Corp. and TBS International Ltd., which were up 233.4% and
224.9%, respectively. NetBank, Inc., Bally Total Fitness Holding Corp. and
AtheroGenics, Inc. recorded the lowest returns within the Index for the first
half of the year, down -93.3%, -80.4% and -78.4%, respectively.

     The Fund will continue to strive to meet its objective of closely
replicating, before expenses, the return of its benchmark, the Russell 2000
Index. It does so by investing in a subset of the securities in the Index such
that the characteristics of the portfolio closely track the characteristics of
the Index.

INTERNATIONAL MARKET OVERVIEW
JUNE 30, 2007 (UNAUDITED)

     In the first quarter of 2007, speculation regarding a slowing U.S. economy
and its effect on demand for foreign goods and commodities, coupled with a
significant correction in the Chinese equity market at the end of February, made
for a volatile period. The global economy proved to be extremely resilient,
however, with most markets managing to eke out gains for the quarter. In Europe,
stocks benefited from continued robust economic expansion and strong corporate
profits. Germany led the way in the region, with its market up 4.9%. The U.K.
market was up 2.5% and France's market advanced 1.7%. Japanese equities posted a
marginal gain of 0.9% for the first quarter, as a decline in business sentiment
(due to uncertainty surrounding the U.S. economy), a minor increase in the yen
and the global sell-off in late February depressed performance.

     Positive momentum returned to the markets in the second half of the period
as corporate activity dominated the headlines. Concerns about the U.S. mortgage
market and rising interest rates around the globe, coupled with another
substantial decline in Shanghai's main stock index in June, were headwinds.
Despite these issues, global equities remained exceptionally resilient, buoyed
by healthy economies and strong corporate earnings. European stocks, in
particular, produced significant gains in the second quarter, thanks to robust
exports and continually strong merger-and-acquisition activity. German stocks
skyrocketed 17.21%, French equities were up 11.40% and U.K. stocks trailed the
pack with a 7.76% gain. As was the case in the first quarter, Japanese stocks
continued to struggle somewhat compared to other developed markets, but still
advanced 4.97% for the quarter.

     The inflation background was fairly benign during the semi-annual period,
though there was some noteworthy central bank activity. In the U.S., the Federal
Reserve Board remained on hold, opting to keep the federal funds target rate
unchanged at 5.25%. In contrast, the European Central Bank ("ECB") continued to
tighten monetary policy, increasing its benchmark interest rate two times (0.25%
each) to end the period at 4.0%. Given the ECB's continued concerns regarding
higher oil prices, wage increase demands and volatile markets, further rate
increases are widely expected. Meanwhile, the Bank of Japan increased its policy
rate by 0.25% to 0.5% in February, but opted to leave the monetary policy
unchanged in June. The U.S. dollar outperformed most major currencies in the
first half of 2007, advancing 2.4% and 2.5% against the euro and pound,
respectively. However, the dollar declined 3.6% versus the yen for the period.

     returns. Investment returns and principal value will vary, and shares may
     be worth more or less at redemption than at original purchase. Performance
     shown is as of date indicated, and current performance may be lower or
     higher than the performance data quoted. To obtain performance as of the

     deduction of taxes a shareholder would pay on distributions or the
     redemption of shares.

2.   The Lipper International Funds Index tracks the results of the 30 largest
     mutual funds in the Lipper International Funds category. Lipper is an
     independent mutual fund research and ranking service. The MSCI EAFE Index
     is a market capitalization weighted index of international stock
     performance composed of equities from developed markets excluding the U.S.
     and Canada. Performance is that of the MSCI EAFE Index through 9/30/01, the
     MSCI Provisional EAFE Index from 10/1/01 through 5/31/02, and the MSCI EAFE
     Index thereafter. One cannot invest directly in an index.

3.   The total annual Fund operating expense ratio in the most recent prospectus
     for the Fund was 0.22%. The expense ratio above may vary from the expense
     ratio presented in other sections of this report that are based on expenses
     incurred during the period covered by this report.

     International markets remained on a persistently upward path during the
first six months of 2007 with all 21 countries in the MSCI EAFE Index ("EAFE")
posting positive returns. The strongest performers were Finland (up 28.8%),
Germany (up 24.7%) and Norway (up 23.8%). Conversely, Japan (up 2.9%), Ireland
(up 2.9%) and Italy (up 6.1%) were the weakest markets.

     All 10 sectors within EAFE recorded positive returns, led by Materials (up
25.7%), Industrials (up 20.1%) and Energy (up 16.9%). The sectors posting the
lowest returns were Health Care (up 1.1%), Financials (up 5.7%) and Information
Technology (up 9.3%).

     The top performing securities were Neptune Orient Lines Ltd. and Leighton
Holdings, with returns of 154.4% and 119.6%, respectively. The worst performers
were Altana and Goodwill Group, with returns of -61.1% and -57.8%, respectively.

     The Fund continues to pursue its objective of closely replicating, before
expenses, the return of its benchmark, the MSCI EAFE Index. It does so by
investing in a subset of the securities in EAFE such that the characteristics of
the portfolio closely track the characteristics of EAFE.

FUND EXPENSES
JUNE 30, 2007 (UNAUDITED)

FUND EXPENSE EXAMPLE

     As a shareholder of a 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 a particular 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 following table provides information about actual account values and
actual expenses. You may use the information in this table, 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
"Expenses Paid During Period" row to estimate the expenses you paid on your
account during this period. Shareholders of the Institutional and PlanAhead
Classes that invest in a 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.

Annualized Expense Ratio .............................        0.63%


HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     The following table provides information about hypothetical account values
and hypothetical expenses based on a 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 a particular Fund with other funds
by contrasting this 5% hypothetical example and the 5% hypothetical examples
that appear in the shareholder reports of the other funds. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. Shareholders of the
Institutional and PlanAhead Classes that invest in a 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 a
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 "Expenses Paid During Period"
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.

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 no load, diversified, open-end management investment
company. These financial statements and notes to the financial statements relate
to the American Beacon S&P 500 Index Fund, the American Beacon Small Cap Index
Fund and the American Beacon International Equity Index Fund (each a "Fund" and
collectively, the "Funds"), each a series of the Trust.

          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.

          Each Fund invests all of its investable assets in a corresponding
portfolio. The State Street Equity 500 Index Portfolio, Master Small Cap Index
Series and the Master International Index Series (each a "Portfolio" and
collectively the "Portfolios") are open-ended management investment companies
registered under the Act. The value of such investment reflects each Fund's
proportionate interest in the net assets of the corresponding Portfolio.



                                                                            % OF PORTFOLIO HELD BY

          The financial statements of the Portfolios are included elsewhere in
this report and should be read in conjunction with the Funds' financial
statements.

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

Class Disclosure

          The S&P 500 Index Fund has two classes of shares designed to meet the
needs of different groups of investors. The following table sets forth the
differences amongst the classes:



CLASS:                OFFERED TO:                                                      SERVICE FEES:
- ------                -----------                                                      -------------
                                                                                 
INSTITUTIONAL CLASS   Investors making an initial investment of $2 million             Administrative Service Fee - 0.05%
PLANAHEAD CLASS       General public and investors investing through an intermediary   Administrative Service Fee - 0.25%
                                                                                                      Service Fee - 0.25%


          Investment income, net capital gains (losses) and all expenses
incurred by the S&P 500 Index Fund are allocated based on the relative net
assets of each class, except for service fees and certain other fees and
expenses related solely to one class of shares.

     Security Valuation

          Valuation of securities by each Portfolio is discussed in the
Portfolio's Notes to Financial Statements, which are included elsewhere in this
report.

<PG$PCN,016000000>

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

    Investment Income

          Each Fund records its share of net investment income and realized and
unrealized gains and losses from the security transactions of its corresponding
Portfolio each day. All net investment income and realized and unrealized gains
(losses) of each Portfolio are allocated pro rata among the investors in that
Portfolio at the time of such determination.

     Dividends to Shareholders

          Dividends from net investment income of the Small Cap Index and
International Equity Index Funds normally will be declared and paid annually.
The S&P 500 Index Fund normally will declare and pay dividends quarterly.
Distributions, if any, of net realized capital gains are generally paid annually
and recorded on the ex-dividend date. Dividends are determined in accordance
with income tax principles that may treat certain transactions differently than
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.

     Valuation of Shares

          The price per share is calculated on each day on which shares are
offered for sale. Net asset value per share is computed by dividing the value of
each Fund's total assets (which includes the value of the Fund's investments in
its Portfolio) less liabilities, by the number of Fund shares outstanding.

     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. FEES AND TRANSACTIONS WITH AFFILIATES

     Administrative Services Agreement

          The Manager and the Trust entered into an Administrative Services
Agreement which obligates the Manager to provide or oversee administrative and
management services to each Fund. As compensation for performing the duties
required under the Administrative Services Agreement, the Manager receives an
annualized fee of 0.05% of the average daily net assets of the Institutional
Class of the S&P 500 Index Fund, International Equity Index Fund and the Small
Cap Index Fund and an annualized fee of 0.25% of the average daily net assets of
the PlanAhead Class of the S&P 500 Index Fund.

     Service Plans

          The Manager and the Trust entered into a Service Plan that obligates
the Manager to oversee additional shareholder servicing of the PlanAhead Class
of S&P 500 Index Fund. As compensation for performing the duties required under
the Service Plan, the Manager receives 0.25% of the average daily net assets of
the PlanAhead Class of the S&P 500 Index Fund.

     Expense Reimbursement Plan

          The Funds have adopted an Expense Reimbursement Plan whereby the
Manager may seek repayment of fees waived or expenses reimbursed for a period of
up to three years. However, reimbursement will occur only if the Class' average
net assets have grown or expenses have declined sufficiently to allow
reimbursement without causing its expense ratio to exceed the previously agreed
upon contractual expense limit. For the six months ended June 30, 2007 there are
no fees subject to recoupment.

     Subadministration Agreement

          The Trust, the Manager and BlackRock Advisors, LLC ("BlackRock")
entered into a Subadministration Agreement that obligates BlackRock to provide
certain other administrative services to the Small Cap Index Fund and the
International Equity Index Fund. As compensation for performing these services,
BlackRock receives an annualized fee of 0.08% of the average daily net assets of
the Small Cap Index Fund and 0.12% of the average daily net assets of the
International Equity Index Fund; however, the fee of each is to be reduced by
the total expense ratio of its corresponding Portfolio, net of any fee waivers.

     Other

          At June 30, 2007, the employee benefit plans of AMR Corporation and
subsidiary companies owned 89.1% of the Institutional Class of the S&P 500 Index
Fund, 98.6% of the Small Cap Index Fund and 84.5% of the International Equity
Index Fund.

3. FEDERAL INCOME AND EXCISE 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 or excise tax provision is required.

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

     The 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):

STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2007 (UNAUDITED)

1. ORGANIZATION

          State Street Master Funds (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
management investment company, and was organized as a business trust under the
laws of The Commonwealth of Massachusetts on July 27, 1999. The Trust comprises
nine investment portfolios: the State Street Equity 500 Index Portfolio, the
State Street Equity 400 Index Portfolio, the State Street Equity 2000 Index
Portfolio, the State Street Aggregate Bond Index Portfolio, the State Street
Money Market Portfolio, the State Street Tax Free Money Market Portfolio, the
State Street Tax Free Limited Duration Bond Portfolio, the State Street Limited
Duration Bond Portfolio and the State Street U.S. Government Money Market
Portfolio. Information presented in these financial statements pertains only to
the State Street Equity 500 Index Portfolio (the "Portfolio"). At June 30, 2007,
only the Portfolio, the State Street Money Market Portfolio, the State Street
Tax Free Money Market Portfolio and the State Street Tax Free Limited Duration
Bond Portfolio were in operation. The Portfolio is authorized to issue an
unlimited number of nontransferable beneficial interests.

          The Portfolio's investment objective is to replicate, as closely as
possible, before expenses, the performance of the Standard & Poor's 500
Composite Stock Price Index (the "S&P 500(R) Index"). The Portfolio uses a
passive management strategy designed to track the performance of the S&P 500(R)
Index. The S&P 500(R) Index is a well-known, unmanaged, stock index that
includes common stocks of 500 companies from several industrial sectors
representing a significant portion of the market value of all stocks publicly
traded in the United States. There is no assurance that the Portfolio will
achieve its objective.

2. SIGNIFICANT ACCOUNTING POLICIES

          The following is a summary of the significant accounting policies
consistently followed by the Portfolio in the preparation of its financial
statements.

Security valuation:

          The Portfolio's investments are valued each business day by
independent pricing services. Equity securities for which market quotations are
available are valued at the last sale price or official closing price (closing
bid price if no sale has occurred) on the primary market or exchange on which
they trade. Investments in other mutual funds are valued at the net asset value
per share. Fixed-income securities and options are valued on the basis of the
closing bid price. Futures contracts are valued on the basis of the last sale
price. Money market instruments maturing within 60 days of the valuation date
are valued at amortized cost, a method by which each money market instrument is
initially valued at cost, and thereafter a constant accretion or amortization of
any discount or premium is recorded until maturity of the security. The
Portfolio may value securities for which market quotations are not readily
available at "fair value," as determined in good faith pursuant to procedures
established by the Board of Trustees.

Securities transactions, investment income and expenses:

          Securities transactions are recorded on a trade date basis for
financial statement purposes. Dividend income is recorded on the ex-dividend
date. Interest income is recorded daily on the accrual basis and includes
amortization of premium and accretion of discount on investments. Realized gains
and losses from securities transactions are recorded on the basis of identified
cost. Expenses are accrued daily based on average daily net assets.

          All of the net investment income and realized and unrealized gains and
losses from the security transactions of the Portfolio are allocated pro rata
among the partners in the Portfolio based on each partner's daily ownership
percentage.

<PG$PCN,036000000>

STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2007 (UNAUDITED)

Federal income taxes:

          The Portfolio is not required to pay federal income taxes on its net
investment income and net capital gains because it is treated as a partnership
for federal income tax purposes. All interest, dividends, gains and losses of
the Portfolio are deemed to have been "passed through" to the Portfolio's
partners in proportion to their holdings in the Portfolio, regardless of whether
such items have been distributed by the Portfolio. Each partner is responsible
for tax liability based on its distributive share; therefore, no provision has
been made for federal income taxes.

Futures:

          The Portfolio may enter into financial futures contracts as part of
its strategy to track the performance of the S&P 500(R) Index. Upon entering
into a futures contract, the Portfolio is required to deposit with the broker
cash or securities in an amount equal to a certain percentage of the contract
amount. Variation margin payments are made or received by the Portfolio each
day, depending on the daily fluctuations in the value of the underlying security
or index, and are recorded for financial statement purposes as unrealized gains
or losses by the Portfolio. The Portfolio recognizes a realized gain or loss
when the contract is closed. The Portfolio voluntarily segregates securities in
an amount equal to the outstanding value of the open futures contracts in
accordance with Securities and Exchange Commission requirements.

          The primary risks associated with the use of futures contracts are an
imperfect correlation between the change in market value of the securities held
by the Portfolio and the prices of futures contracts and the possibility of an
illiquid market.

          Use of Estimates: The Portfolio's financial statements are prepared in
accordance with U.S. generally accepted accounting principles that require the
use of management estimates. Actual results could differ from those estimates.

3. SECURITIES TRANSACTIONS

          For the six months ended June 30, 2007, purchases and sales of
investment securities, excluding short-term investments, futures contracts, and
in-kind contributions and withdrawals, aggregated to $181,886,420 and
$350,888,232, respectively. The aggregate value of in-kind contributions was $0.

          At June 30, 2007, the book cost of investments was $1,639,060,910
which approximates cost computed on a federal tax basis. The aggregate gross
unrealized appreciation and gross unrealized depreciation was $1,127,577,940 and
$41,510,236, respectively, resulting in net appreciation of $1,086,067,704 for
all securities as computed on a federal income tax basis.

          The differences between book and tax cost amounts are primarily due to
wash sale loss deferrals.

4. RELATED PARTY FEES AND TRANSACTIONS

          The Portfolio has entered into an investment advisory agreement with
SSgA Funds Management, Inc. ("SSgA FM" or the "Adviser"), a subsidiary of State
Street Corp. and an affiliate of State Street Bank and Trust Company ("State
Street"), under which SSgA FM directs the investments of the Portfolio in
accordance with its investment objective, policies, and limitations. The Trust
has contracted with State Street to provide custody, administration and transfer
agent services to the Portfolio. In compensation for SSgA FM's services as
investment adviser and for State Street's services as administrator, custodian
and transfer agent (and for assuming ordinary operating expenses of the
Portfolio, including ordinary legal, audit and trustees expense),

<PG$PCN,037000000>

STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2007 (UNAUDITED)

State Street receives a unitary fee, calculated daily, at the annual rate of
0.045% of the Portfolio's average daily net assets.

          Certain investments made by the Portfolio were made in securities
affiliated with State Street and SSgA FM. Investments in State Street Corp., the
holding company of State Street, were made according to its representative
portion of the S&P 500(R) Index. The market value of this investment at June 30,
2007 is listed in the Portfolio of Investments.

5. TRUSTEES' FEES

          Pursuant to certain agreements with State Street and its affiliates,
each Independent Trustee receives for his or her services a $30,000 retainer in
addition to $2,500 for each in-person meeting and $500 for each telephonic
meeting from State Street or its affiliates.

6. INDEMNIFICATIONS

          The Trust's organizational documents provide that its officers and
trustees are indemnified against certain liabilities arising out of the
performance of their duties to the Trust. In addition, both in some of its
principal service contracts and in the normal course of its business, the Trust
enters into contracts that provide indemnifications to other parties for certain
types of losses or liabilities. The Trust's maximum exposure under these
arrangements is unknown as this could involve future claims against the Trust.

7. NEW 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 for 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 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 a more-likely-than-not threshold
would be recorded as a tax expense in the current year. Adoption of FIN 48 is
required for fiscal years beginning after December 15, 2006 and is to be applied
to all open tax years as of the effective date. Recent SEC guidance allows
implementing FIN 48 in portfolio NAV calculations as late as the Portfolio's
last NAV calculation in the first required financial statement reporting period.
As a result, the Portfolio has incorporated FIN 48 in its semi annual report at
June 30, 2007. At this time, management has evaluated the implication of FIN 48
and there is no impact to the financial statements.

          In addition, in September 2006, Statement of Accounting Standards No.
157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have, if any, on the Portfolio's financial statement
disclosures.

Notes to Financial Statements (Unaudited)          MASTER SMALL CAP INDEX SERIES

1. SIGNIFICANT ACCOUNTING POLICIES:

Master Small Cap Index Series (the "Series"), a non-diversified investment
company, is part of Quantitative Master Series LLC (the "Master LLC"). The
Master LLC is registered under the Investment Company Act of 1940, as amended,
and is organized as a Delaware limited liability company. Prior to June 15,
2007, the Master LLC was organized as a Delaware statutory trust (the "Trust").
The Limited Liability Company Agreement (the "LLC Agreement") permits the
Directors (and prior to June 15, 2007, the Declaration of Trust permitted the
Trustees) to issue non-transferable interests in the Series subject to certain
limitations. Throughout this report the Trust and the Master LLC are referred to
as the Master LLC and the Board of Trustees is referred to as the Board of
Directors. The Series' financial statements are prepared in conformity with U.S.
generally accepted accounting principles, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates. These unaudited financial statements reflect all adjustments, which
are, in the opinion of management, necessary to present a fair statement of the
results for the interim period. All such adjustments are of a normal, recurring
nature. The following is a summary of significant accounting policies followed
by the Series.

(A) VALUATION OF INVESTMENTS -- Equity securities that are held by the Series
that are traded on stock exchanges or the NASDAQ Global Market are valued at the
last sale price or official close price on the exchange, as of the close of
business on the day the securities are being valued or, lacking any sales, at
the last available bid price for long positions, and at the last available asked
price for short positions. In cases where equity securities are traded on more
than one exchange, the securities are valued on the exchange designated as the
primary market by or under the authority of the Board of Directors of the Master
LLC. Long positions traded in the over-the-counter ("OTC") market, NASDAQ
Capital Market or Bulletin Board are valued at the last available bid price or
yield equivalent obtained from one or more dealers or pricing services approved
by the Board of Directors of the Master LLC. Short positions traded in the OTC
market are valued at the last available asked price. Portfolio securities that
are traded both in the OTC market and on a stock exchange are valued according
to the broadest and most representative market.

Options written or purchased are valued at the last sale price in the case of
exchange-traded options. Options traded in the OTC market are valued at the last
asked price (options written) or the last bid price (options purchased). Swap
agreements are valued based upon quoted fair valuations received daily by the
Series from a pricing service or counterparty. Financial futures contracts and
options thereon, which are traded on exchanges, are valued at their last sale
price as of the close of such exchanges. Valuation of short-term investment
vehicles is generally based on the net asset value of the underlying investment
vehicle or amortized cost.

Repurchase agreements are valued at cost plus accrued interest. The Series
employs pricing services to provide certain securities prices for the Series.
Securities and assets for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the direction of
the Board of Directors of the Master LLC, including valuations furnished by the
pricing services retained by the Series, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are reviewed
by the officers of the Master LLC under the general supervision by the Board of
Directors of the Master LLC. Such valuations and procedures will be reviewed
periodically by the Board of Directors of the Master LLC.

Generally, trading in foreign securities, as well as U.S. government securities,
money market instruments and certain fixed income securities is substantially
completed each day at various times prior to the close of business on the New
York Stock Exchange ("NYSE"). The values of such securities used in computing
the net assets of the Series are determined as of such times. Foreign currency
exchange rates are generally determined as of the close of business on the NYSE.
Occasionally, events affecting the values of such securities and such exchange
rates may occur between the times at which they are determined and the close of
business on the NYSE that may not be reflected in the computation of the Series'
net assets. If events (for example,a company announcement, market volatility or
a natural disaster) occur during such periods that are expected to materially
affect the value of such securities,those securities will be valued at their
fair value as determined in good faith by the Board of Directors of the Master
LLC or by BlackRock Advisors, LLC ("the Manager"), an indirect, wholly owned
subsidiary of BlackRock, Inc., using a pricing service and/or procedures
approved by the Board of Directors of the Master LLC.

(B) DERIVATIVE FINANCIAL INSTRUMENTS -- The Series may engage in various
portfolio investment strategies both to increase the return of the Series and to
hedge, or protect, its exposure to interest rate movements and movements in the
securities markets. Losses may arise due to changes in the value of the contract
or if the counterparty does not perform under the contract.

<PG$PCN,049000000>

Notes to Financial Statements (continued)          MASTER SMALL CAP INDEX SERIES

- -    Financial futures contracts -- The Series may purchase or sell financial
     futures contracts and options on such financial futures contracts.
     Financial futures contracts are contracts for delayed delivery of
     securities at a specific future date and at a specified price or yield.
     Upon entering into a contract, the Series deposits, and maintains, as
     collateral such initial margin as required by the exchange on which the
     transaction is effected. Pursuant to the contract,the Series agrees to
     receive from or pay to the broker an amount of cash equal to the daily
     fluctuation in value of the contract. Such receipts or payments are known
     as variation margin and are recorded by the Series as unrealized gains or
     losses. When the contract is closed, the Series records a realized gain or
     loss equal to the difference between the value of the contract at the time
     it was opened and the value at the time it was closed.

- -    Options -- The Series may purchase and write call and put options. When the
     Series writes an option,an amount equal to the premium received by the
     Series is reflected as an asset and an equivalent liability. The amount of
     the liability is subsequently marked-to-market to reflect the current
     market value of the option written. When a security is purchased or sold
     through an exercise of an option, the related premium paid (or received) is
     added to (or deducted from) the basis of the security acquired or deducted
     from (or added to) the proceeds of the security sold. When an option
     expires (or the Series enters into a closing transaction), the Series
     realizes a gain or loss on the option to the extent of the premiums
     received or paid (or a gain or loss to the extent that the cost of the
     closing transaction exceeds the premium paid or received).

    Written and purchased options are non-income producing investments.

(C) INCOME TAXES -- The Series is classified as a partnership for federal income
tax purposes. As such,each investor in the Series is treated as owner of its
proportionate share of the net assets, income, expenses and realized and
unrealized gains and losses of the Series. Therefore, no federal income tax
provision is required. Under the applicable foreign tax law, a withholding tax
may be imposed on interest, dividends and capital gains at various rates. It is
intended that the Series' assets will be managed so an investor in the Series
can satisfy the requirements of Subchapter M of the Internal Revenue Code.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are
accounted for on the date the securities are purchased or sold (the trade
dates). Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis.

(E) SECURITIES LENDING -- The Series may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities. The
market value of the loaned securities is determined at the close of business of
the Series and any additional required collateral is delivered to the Series on
the next business day. Where the Series receives securities as collateral for
the loaned securities, it collects a fee from the borrower. The Series typically
receives the income on the loaned securities but does not receive the income on
the collateral. Where the Series receives cash collateral, it may invest such
collateral and retain the amount earned on such investment, net of any amount
rebated to the borrower. Loans of securities are terminable at any time and the
borrower, after notice,is required to return borrowed securities within five
business days. The Series may pay reasonable finder's, lending agent,
administrative and custodial fees in connection with its loans. In the event
that the borrower defaults on its obligation to return borrowed securities
because of insolvency or for any other reason,the Series could experience delays
and costs in gaining access to the collateral. The Series also could suffer a
loss where the value of the collateral falls below the market value of the
borrowed securities, in the event of borrower default or in the event of losses
on investments made with cash collateral.

(F) RECENT ACCOUNTING PRONOUNCEMENTS -- Effective June 29,2007,the Master LLC
implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48,
"Accounting for Uncertainty in Income Taxes -- an interpretation of FASB
Statement No. 109 "("FIN 48").FIN 48 prescribes the minimum recognition
threshold a tax position must meet in connection with accounting for
uncertainties in income tax positions taken or expected to be taken by an
entity, including investment companies, before being measured and recognized in
the financial statements. Management has evaluated the application of FIN 48 to
the Master LLC,and has determined that the adoption of FIN 48 does not have a
material impact on the Master LLC's financial statements. The Master LLC files
U.S. and various state tax returns. No income tax returns are currently under
examination. The statute of limitations on the Master LLC's tax returns remains
open for the years ended December 31, 2003, through December 31, 2006.


JUNE 30, 2007                                                                 47

Notes to Financial Statements (concluded)          MASTER SMALL CAP INDEX SERIES

In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements"("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS 157
and its impact on the Fund's financial statements, if any, has not been
determined.

In addition,in February 2007,Statement of Financial Accounting Standards No.
159, "The Fair Value Option for Financial Assets and Financial Liabilities"
("FAS 159"), was issued and is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157. FAS 159 permits entities to choose to
measure many financial instruments and certain other items at fair value that
are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. At this time, management is evaluating
the implications of FAS 159 and its impact on the Fund's financial statements,if
any, has not been determined.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Master LLC has entered into an Investment Advisory Agreement with the
Manager. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial
Services Group, Inc. are the principal owners of BlackRock, Inc.

The Manager is responsible for the management of the Series' investments and
provides the necessary personnel, facilities,equipment and certain other
services necessary to the operations of the Series. For such services,the Series
pays a monthly fee at an annual rate of .01% of the average daily value of the
Series' net assets. The Manager has entered into a contractual arrangement with
the Series under which all expenses incurred by the Series will not exceed .08%.
This arrangement has a one-year term and is renewable.

In addition,the Manager has entered into a sub-advisory agreement with BlackRock
Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the
Manager pays BIM for services it provides a monthly fee of an annual rate that
is a percentage of the management fee paid by the Series to the Manager.

Merrill Lynch Trust Company ("MLTC"), an indirect, wholly owned subsidiary of
Merrill Lynch, is the Series' custodian. Effective July 17, 2007, State Street
Bank&Trust Co. became the Series' custodian.

The Master LLC has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill
Lynch, or its affiliates. As of June 30, 2007, the Series lent securities with a
value of $88,142 to MLPF&S or its affiliates. Pursuant to that order, the Master
LLC has retained BIM as the securities lending agent for a fee based on a share
of the returns on investment of cash collateral. BIM may, on behalf of the
Master LLC and the Series, invest cash collateral received by the Series for
such loans, among other things, in a private investment company managed by the
Manager or in registered money market funds advised by the Manager or its
affiliates. For the six months ended June 30, 2007, BIM received $118,728 in
securities lending agent fees.

For the six months ended June 30, 2007, the Series reimbursed the Manager $5,829
for certain accounting services.

Certain officers and/or trustees of the Master LLC are officers and/or directors
of BlackRock, Inc. or its affiliates.

3. INVESTMENTS:

Purchases and sales (including in-kind redemptions) of investments,excluding
short-term securities,for the six months ended June 30, 2007 were $258,417,198
and $98,031,953, respectively.

4. SHORT-TERM BORROWINGS:

The Master LLC, on behalf of the Series, along with certain other funds managed
by the Manager and its affiliates, is party to a $500,000,000 credit agreement
with a group of lenders which expires November 2007. The Series may borrow under
the credit agreement to fund shareholder redemptions and for other lawful
purposes other than for leverage. The Series may borrow up to the maximum amount
allowable under the Series' current prospectus and statement of additional
information, subject to various other legal,regulatory or contractual limits.
The Series pays a commitment fee of .06% per annum based on the fund's pro rata
share of the unused portion of the credit agreement. Amounts borrowed under the
credit agreement bear interest at a rate equal to, at each fund's election, the
federal funds rate plus .35% or a base rate as defined in the credit agreement.
The Series did not borrow under the credit agreement during the six months ended
June 30, 2007.

Notes to Financial Statements (Unaudited)      MASTER INTERNATIONAL INDEX SERIES

1. SIGNIFICANT ACCOUNTING POLICIES:

Master International Index Series (the "Series"), a non-diversified investment
company,is part of Quantitative Master Series LLC (the "Master LLC"). The Master
LLC is registered under the Investment Company Act of 1940,as amended, and is
organized as a Delaware limited liability company. Prior to June 15,2007, the
Master LLC was organized as a Delaware statutory trust (the "Trust"). The Master
LLC's Limited Liability Company Agreement (the "LLC Agreement") permits the
Directors (and prior to June 15, 2007, the Declaration of Trust permitted the
Trustees) to issue non-transferable interests in the Series, subject to certain
limitations. Throughout this report the Trust and the Master LLC are referred to
as the Master LLC and the Board of Trustees is referred to as the Board of
Directors. The Series' financial statements are prepared in conformity with U.S.
generally accepted accounting principles,which may require the use of management
accruals and estimates. Actual results may differ from these estimates. These
unaudited financial statements reflect all adjustments,which are, in the opinion
of management, necessary to present a fair statement of the results for the
interim period. All such adjustments are of a normal, recurring nature. The
following is a summary of significant accounting policies followed by the
Series.

(a) Valuation of investments -- Equity securities that are held by the Series
that are traded on stock exchanges or the NASDAQ Global Market are valued at the
last sale price or official close price on the exchange, as of the close of
business on the day the securities are being valued or, lacking any sales, at
the last available bid price for long positions, and at the last available asked
price for short positions. In cases where equity securities are traded on more
than one exchange, the securities are valued on the exchange designated as the
primary market by or under the authority of the Board of Directors of the Master
LLC. Long positions traded in the over-the-counter ("OTC") markets, NASDAQ
Capital Market or Bulletin Board are valued at the last available bid price or
yield equivalent obtained from one or more dealers or pricing services approved
by the Board of Directors of the Master LLC. Short positions traded in the OTC
markets are valued at the last available asked price. Portfolio securities that
are traded both in the OTC markets and on a stock exchange are valued according
to the broadest and most representative market.

Options written or purchased are valued at the last sale price in the case of
exchange-traded options. Options traded in the OTC market are valued at the last
asked price (options written) or the last bid price (options purchased). Swap
agreements are valued based upon quoted fair valuations received daily by the
Series from a pricing service or counter-party. Financial futures contracts and
options thereon, which are traded on exchanges, are valued at their last sale
price as of the close of such exchanges. Valuation of short-term investment
vehicles is generally based on the net asset value of the underlying investment
vehicle or amortized cost.

Repurchase agreements are valued at cost plus accrued interest. The Series
employs pricing services to provide certain securities prices for the Series.
Securities and assets for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the direction of
the Board of Directors of the Master LLC, including valuations furnished by the
pricing services retained by the Series, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are reviewed
by the officers of the Series under the general supervision of the Master LLC's
Board of Directors. Such valuations and procedures will be reviewed periodically
by the Board of Directors of the Master LLC.

Generally, trading in foreign securities,as well as U.S. government securities
and money market instruments and certain fixed income securities, is
substantially completed each day at various times prior to the close of business
on the New York Stock Exchange ("NYSE"). The values of such securities used in
computing the net assets of the Series are determined as of such times. Foreign
currency exchange rates will generally be determined as of the close of business
on the NYSE. Occasionally,events affecting the values of such securities and
such exchange rates may occur between the times at which they are determined and
the close of business on the NYSE that may not be reflected in the computation
of the Series' net assets. If events (for example, a company announcement,
market volatility or a natural disaster) occur during such periods that are
expected to materially affect the value of such securities, those securities
will be valued at their fair value as determined in good faith by the Master
LLC's Board of Directors or by Black Rock Advisors, LLC (the "Manager"), an
indirect, wholly owned subsidiary of Black Rock, Inc., using a pricing service
and/or procedures approved by the Master LLC's Board of Directors.

(b) Derivative financial instruments -- The Series may engage in various
portfolio investment strategies to provide liquidity or as a proxy for a direct
investment in securities underlying the Series' index. Losses may arise due to
changes in the value of the contract due to an unfavorable change in the price
of the underlying security or if the counterparty does not perform under the
contract. The counterparty for certain instruments may pledge cash or securities
as collateral.


JUNE 30, 2007                                                                 57

<PG$PCN,060000000>

Notes to Financial Statements (continued)      MASTER INTERNATIONAL INDEX SERIES

- -    Financial futures contracts -- The Series may purchase or sell financial
     futures contracts and options on such financial futures contracts.
     Financial futures contracts are contracts for delayed delivery of
     securities at a specific future date and at a specific price or yield. Upon
     entering into a contract, the Series deposits and maintains as collateral
     such initial margin as required by the exchange on which the transaction is
     effected. Pursuant to the contract, the Series agrees to receive from or
     pay to the broker an amount of cash equal to the daily fluctuation in value
     of the contract. Such receipts or payments are known as variation margin
     and are recorded by the Series as unrealized gains or losses. When the
     contract is closed, the Series records a realized gain or loss equal to the
     difference between the value of the contract at the time it was opened and
     the value at the time it was closed.

- -    Options -- The Series may purchase and write call and put options. When the
     Series writes an option,an amount equal to the premium received by the
     Series is reflected as an asset and an equivalent liability. The amount of
     the liability is subsequently marked-to-market to reflect the current
     market value of the option written. When a security is purchased or sold
     through an exercise of an option, the related premium paid (or received) is
     added to(or deducted from) the basis of the security acquired or deducted
     from (or added to) the proceeds of the security sold. When an option
     expires (or the Series enters into a closing transaction), the Series
     realizes a gain or loss on the option to the extent of the premiums
     received or paid (or a gain or loss to the extent that the cost of the
     closing transaction exceeds the premium paid or received).

     Written and purchased options are non-income producing investments.

- -    Forward foreign exchange contracts -- The Series may enter into forward
     foreign exchange contracts as a hedge against either specific transactions
     or portfolio positions. The contract is marked-to-market daily and the
     change in market value is recorded by the Series as an unrealized gain or
     loss. When the contract is closed,the Series records a realized gain or
     loss equal to the difference between the value at the time it was opened
     and the value at the time it was closed.

- -    Foreign currency options and futures -- The Series may also purchase or
     sell listed or OTC foreign currency options, foreign currency futures and
     related options on foreign currency futures as a short or long hedge
     against possible variations in foreign exchange rates. Such transactions
     may be effected with respect to hedges on non-U.S. dollar-denominated
     securities owned by the Series, sold by the Series but not yet delivered,or
     committed or anticipated to be purchased by the Series.

(c) Foreign currency transactions -- Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets or liabilities expressed in
foreign currencies into U.S. dollars. Realized and unrealized gains or losses
from investments include the effects of foreign exchange rates on investments.
The Series invests in foreign securities, which may involve a number of risk
factors and special considerations not present with investments in securities of
U.S. corporations.

(d) Income taxes -- The Series is classified as a partnership for federal income
tax purposes. As such, each investor in the Series is treated as owner of its
proportionate share of the net assets, income, expenses and realized and
unrealized gains and losses of the Series. Therefore, no federal income tax
provision is required. Under the applicable foreign tax law, a withholding tax
may be imposed on interest, dividends and capital gains at various rates. It is
intended that the Series' assets will be managed so an investor in the Series
can satisfy the requirements of Subchapter M of the Internal Revenue Code.

(e) Security transactions and investment income -- Security transactions are
accounted for on the date the securities are purchased or sold (the trade
dates). Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend
dates. Dividends from foreign securities where the ex-dividend date may have
passed are subsequently recorded when the Series has determined the ex-dividend
date. Interest income is recognized on the accrual basis.

(f) Securities lending -- The Series may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities. The
market value of the loaned securities is determined at the close of business of
the Series and any additional required collateral is delivered to the Series on
the next business day. Where the Series receives securities as collateral for
the loaned securities, it collects a fee from the borrower. The Series typically
receives the income on the loaned securities


58                                                                 JUNE 30, 2007

<PG$PCN,061000000>

Notes to Financial Statements (continued)      MASTER INTERNATIONAL INDEX SERIES

but does not receive the income on the collateral. Where the Series receives
cash collateral, it may invest such collateral and retain the amount earned on
such investment, net of any amount rebated to the borrower. Loans of securities
are terminable at any time and the borrower, after notice, is required to return
borrowed securities within five business days. The Series may pay reasonable
finder's, lending agent, administrative and custodial fees in connection with
its loans. In the event that the borrower defaults on its obligation to return
borrowed securities because of insolvency or for any other reason, the Series
also could suffer a loss where the value of the collateral falls below the
market value of the borrowed securities, in the event of borrower default or in
the event of losses on investments made with cash collateral.

(g) Recent accounting pronouncements -- Effective June 29, 2007, the Series
implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48,
"Accounting for Uncertainty in Income Taxes -- an interpretation of FASB
Statement No. 109"("FIN 48"). FIN 48 prescribes the minimum recognition
threshold a tax position must meet in connection with accounting for
uncertainties in income tax positions taken or expected to be taken by an
entity, including investment companies, before being measured and recognized in
the financial statements. Management has evaluated the application of FIN 48 to
the Series,and has determined that the adoption of FIN 48 does not have a
material impact on the Series' financial statements. The Series files U.S. and
various state tax returns. No income tax returns are currently under
examination. The statute of limitations on the Series' tax returns remains open
for the years ended December 31, 2003 through December 31, 2006.

In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS 157
and its impact on the Series' financial statements, if any, has not been
determined.

In addition, in February 2007, Statement of Financial Accounting Standards No.
159, "The Fair Value Option for Financial Assets and Financial Liabilities"
("FAS 159"), was issued and is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157.

FAS 159 permits entities to choose to measure many financial instruments and
certain other items at fair value that are not currently required to be measured
at fair value. FAS 159 also establishes presentation and disclosure requirements
designed to facilitate comparisons between entities that choose different
measurement attributes for similar types of assets and liabilities. At this
time, management is evaluating the implications of FAS 159 and its impact on the
Series' financial statements, if any, has not been determined.

(h) Bank overdraft -- The Series recorded a bank overdraft which resulted from
management estimates of available cash.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Master LLC has entered into an Investment Advisory Agreement with the
Manager. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial
Services Group, Inc. are the principal owners of BlackRock, Inc.

The Manager is responsible for the management of the Series' investments and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Series. For such services, the
Series pays a monthly fee at an annual rate of .01% of the average daily value
of the Series' net assets. The Manager has entered into a contractual
arrangement with the Series under which the expenses incurred by the Series will
not exceed .12%. This arrangement has a one-year term and is renewable.

In addition, the Manager has entered into a sub-advisory agreement with
BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under
which the Manager pays BIM for services it provides a monthly fee at an annual
rate that is a percentage of the management fee paid by the Series to the
Manager.

For the six months ended June 30, 2007, the Series reimbursed the Manager $8,962
for certain accounting services.

In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated, a wholly owned
subsidiary of Merrill Lynch,or its affiliates, received $40,963 in commissions
on the execution of portfolio security transactions for the Series for the six
months ended June 30, 2007.

Certain officers and/or directors of the Master LLC are officers and/or
directors of BlackRock, Inc. or its affiliates.


JUNE 30, 2007                                                                 59

5. SHORT-TERM BORROWINGS:

The Master LLC, on behalf of the Series, along with certain other funds managed
by the Manager and its affiliates, is a party to a $500,000,000 credit agreement
with a group of lenders, which expires November 2007. The Series may borrow
under the credit agreement to fund shareholder redemptions and for other lawful
purposes other than for leverage. The Series may borrow up to the maximum amount
allowable under the Series' current prospectus and statement of additional
information, subject to various other legal, regulatory or contractual limits.
The Series pays a commitment fee of .06% per annum based on the Series' pro rata
share of the unused portion of the credit agreement. Amounts borrowed under the
credit agreement bear interest at a rate equal to, at each fund's election, the
federal funds rate plus .35% or a base rate as defined in the credit agreement.
The Series did not borrow under the credit agreement during the six months ended
June 30,2007.

INTERIM RENEWAL

In prior years, the Board of Trustees ("Board" or "Trustees") typically has
considered the annual renewal of the existing Management Agreement between
American Beacon Advisors, Inc. (the "Manager") and the American Beacon Funds
(the "Trust"), on behalf of the International Equity Index, S&P 500 Index, and
Small Cap Index Funds (each, a "Fund" and collectively, the "Funds"), at the
Board meeting held in the first quarter of each year. 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 Agreement 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. The Board considered that the Manager's fee rate schedule for
the Funds 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 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 Investment Committee meetings
throughout the year.

In considering the renewal of the Management Agreement with the Manager with
respect to the International Equity Index Fund, the Trustees considered that the
Fund outperformed both its benchmark index and the respective Lipper index for
the 2006 calendar year. In considering the renewal of the Management Agreement
with the Manager with respect to the S&P 500 Index Fund, the Trustees considered
that the Fund outperformed its benchmark index (before the deduction of fund
expenses) and its respective Lipper index for the 2006 calendar year. In
considering the renewal of the Management Agreement with the Manager with
respect to the Small Cap Index Fund, the Trustees considered that the Fund
outperformed its respective Lipper index and underperformed its benchmark index
for the 2006 calendar year.

Based on these considerations, among others, 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 existing
Management Agreement. In preparation for the Board's consideration to renew the
Management Agreement, 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 comparison of the 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;

     -    a description of any payments by the firm to support the Funds'
          marketing efforts;

     -    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 the Manager's 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 discussion of whether the Manager receives, with respect to the
          Funds, other compensation, including any payment for order flow or ECN
          liquidity rebates;

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

     -    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;

          Funds;

          service providers to the Funds pursuant to which the Manager receives
          direct or indirect benefits from the service provider; 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 and
Investment Advisory 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 Agreement, 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 Agreement,
the Trustees considered the best interests of each Fund separately. In addition,
while the Management Agreement for all of the Funds was 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.

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 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,

<PG$PCN,066000000>

DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT AGREEMENT
OF THE FUNDS (UNAUDITED)

including the addition of a separate new information technology (IT) department
at the Manager; the high rankings received by the Funds in service surveys; and
the active role played by the Manager in monitoring and, as appropriate,
recommending replacements for the master portfolios.

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 the 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 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. The Funds operate
under a master-feeder structure whereby each Fund invests all of its assets in a
master portfolio that is not managed by the Manager. As such, the Board
considered that the Manager does not receive a management fee with respect to
the Funds.

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. 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 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's 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 expanding the level of assets
under management by the Manager. In addition, the Board noted that the Manager
provides services to the Trust at a relatively low cost, and the benefit plans
of AMR Corporation have invested a substantial number of assets in the Funds,
which helps reduce costs.

DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT AGREEMENT
OF THE FUNDS (UNAUDITED)

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

ADDITIONAL CONSIDERATIONS AND CONCLUSIONS WITH RESPECT TO EACH FUND

The performance comparisons below were made versus each Fund's Lipper peer
universe median. 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 International
Equity Index Fund. In considering the renewal of the Management Agreement with
respect to the International Equity Index Fund (the "Fund"), the Trustees
considered the following additional factors: (1) the performance of the Fund was
higher than its Lipper peer universe median for the one-, three- and five-year
periods; (2) the Fund's actual management fee (including administrative fees)
and the total expense ratio was lower than the Lipper expense group median.

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 S&P 500 Index
Fund. In considering the renewal of the Management Agreement with respect to the
S&P 500 Index Fund (the "Fund"), the Trustees considered the following
additional factors: (1) the Fund outperformed its peer universe median for the
one-, three-, five- and ten-year periods; and (2) the Fund's actual management
fee (including administrative fees) and the total expense ratio was lower than
its Lipper expense group median.

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 Small Cap Index
Fund. In considering the renewal of the Management Agreement with respect to the
Small Cap Index Fund (the "Fund"), the Trustees considered the following
additional factors: (1) the Fund outperformed its peer universe median for the
one-year period and underperformed for the three- and five-year periods; and (2)
the Fund's actual management fee (including administrative fees) and the total
expense ratio was lower than its Lipper expense group median.

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.

Investing in debt securities entails interest rate risk which is the risk that
debt securities will decrease in value with increases in market interest rates.

MARKET OVERVIEW
JUNE 30, 2007 (UNAUDITED)

          A sudden global risk aversion trade in late-February brought the first
meaningful correction in equity prices in nine months and initiated a
significant rally in high-quality bond markets. During the first half of 2007,
the Lehman Brothers U.S. 1-10 year TIPS Index returned 2.49% while the Lehman
Brothers Aggregate Index returned 0.98%. During the second quarter, real yields
were markedly higher as strong economic data and increased growth projections
diminished the probability of a near-term ease by the Federal Reserve Board. The
ten-year Treasure Inflation Protected Securities ("TIPS") yield reached a
multi-year high of over 2.75% during the period before ending the first half of
the year at 2.65%. Through June, year-over-year Consumer Price Index ("CPI") had
advanced at a 2.7% clip. Current TIPS valuations suggest that investors project
CPI to average 2.4% annually over the next decade. This is well below the 3.1%
average of the past 25 years.

          Due to the decrease in the federal budget deficit, the U.S. Treasury
("Treasury") has been lowering their borrowing requirements and cutting back
TIPS auctions by about 20%. The Treasury auctioned $6.0 billion of 10-year TIPS
in April and the auction was met with reasonably strong demand. TIPS yields rose
during the first half of the year and the real yield curve flattened in shape.
The most pronounced increase was in the short portion of the curve where real
yields rose by 0.33%. Yields on five-year and 30-year TIPS rose by 0.20% and
0.26%, respectively.

JUNE 30, 2007 (UNAUDITED)

          The Institutional Class of the Fund returned 2.10% for the period from
January 1, 2007 through June 30, 2007, trailing the Lehman Brothers 1-10 Yr U.S.

1.   Performance shown is historical and may not be indicative of future
     returns. Investment returns and principal value will vary, and shares may
     be worth more or less at redemption than at original purchase. Performance
     shown is as of date indicated, and current performance may be lower or
     higher than the performance data quoted. To obtain performance as of the
     most recent month end, please visit www.americanbeaconfunds.com or call
     1-800-967-9009. Fund performance in the table above does not reflect the
     deduction of taxes a shareholder would pay on distributions or the
     redemption of shares.

2.   The Lehman Bros. 1-10 Yr. U.S. TIPS Index is an unmanaged market index
     comprising U.S. Treasury inflation-indexed securities with maturities
     between one and ten years while the Lehman Bros. U.S. TIPS Index includes
     all maturities. The Lipper TIPS Funds Index tracks the results of the 30
     largest mutual funds in the Lipper TIPS Fund category. Lipper is an
     independent mutual fund research and ranking service. One cannot directly
     invest in an index.

3.   The total annual Fund operating expense ratio set forth in the most recent
     Fund prospectus for the Fund was 0.49%. After contractual expense
     reimbursements through February 28, 2008, the net expense ratio disclosed
     in the most recent prospectus was 0.35%. The expense ratios above may vary
     from the expense ratios presented in other sections of this report that are
     based on expenses incurred during the period covered by this report.

          The Fund underperformed the Index for the six-month period by 39 basis
points. While part of the underperformance can be attributed to Fund expenses,
sub-advisor performance also negatively impacted the Fund over the past six
months. The underperformance occurred in both the first and second quarters of
the year. In the first quarter, exposure to non-Index securities (U.S. corporate
inflation-linked bonds and German and French government inflation-linked bonds)
hurt performance as spreads between corporate and government yields widened. In
the second quarter, non-U.S. government inflation-linked bonds continued to
underperform, and an overweight position in intermediate-term TIPS subtracted
value as the TIPS yield curve flattened. Lastly, the Fund held a position in the
inflation-linked debt of the Student Loan Marketing Association ("SLMA"). This
position was negatively impacted by the structure of a pending private equity
transaction which would subordinate current SLMA unsecured bondholders.

          The Fund remains focused on investing primarily in TIPS to provide
inflation protection and income to its shareholders.

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 first 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.

   (5% return before expenses)


*    Expenses are equal to the Fund's annualized expense ratio for the six-month
     period of 0.40% for the Institutional Class, 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 TREASURY INFLATION PROTECTED SECURITIES FUND
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2007 (UNAUDITED)

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 no load, diversified, open-end management investment
company. These financial statements and notes to the financial statements relate
to the American Beacon Treasury Inflation Protected Securities Fund (the
"Fund"), a series of the Trust.

          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.

     Security Valuation

          Investments are valued at the close of the New York Stock Exchange
(the "Exchange"), normally 4 p.m. ET, each day that the Exchange is open for
business.

          Debt securities (other than short-term securities) normally are valued
on the basis of prices provided by an independent pricing service and may take
into account appropriate factors such as institution-size trading in similar
groups of securities, yield, quality, coupon rate, maturity, type of issue,
trading characteristics and other market data. When a price is unavailable from
a pricing service or when the price provided by the pricing service is deemed
not to represent fair value, the prices of debt securities may be determined
using quotes obtained from brokers.

          Investments in mutual funds are valued at the closing net asset value
per share of the mutual fund on the day of valuation. Investment grade
short-term obligations with 60 days or less to maturity are valued using the
amortized cost method, which approximates market value.

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

     Security Transactions and Investment Income

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

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

          Inflation-indexed bonds are fixed-income securities whose principal
value is periodically adjusted to the rate of inflation. Interest is accrued
based on the principal value, which is adjusted for inflation. Any increase in
the principal amount of an inflation-indexed bond is recorded as interest
income, even though principal is not received until maturity.

AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND
NOTES TO FINANCIAL STATEMENTS

     Dividends to Shareholders

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

     Currency Translation

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

     Forward Foreign Currency Exchange Contracts

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

     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 fund management. Investment assets of the Fund are
managed by multiple investment advisors which have entered into separate
investment advisory agreements with the Manager. As compensation for performing
the duties required under the Management Agreement, the Manager receives from
the Fund an annualized fee equal to 0.10% of the average daily net assets plus
amounts paid by the Manager to the investment advisors hired by the Manager to
direct investment activities of the Fund. Management fees paid during the six
months ended June 30, 2007 were as follows:



                          AMOUNTS PAID TO   NET AMOUNTS
MANAGEMENT   MANAGEMENT      INVESTMENT     RETAINED BY
 FEE RATE        FEE          ADVISORS        MANAGER
- ----------   ----------   ---------------   -----------
                                   
   0.22%       $42,232        $23,036         $19,196


     Administrative Services Agreement

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

     Investment in Affiliated Funds

          The Fund is permitted, pursuant to an exemptive order by the
Securities and Exchange Commission ("SEC") and procedures approved by the Board,
to invest up to 25% of its total assets in the American Beacon Money Market
Select Fund (the "Select Fund"). The Fund and the Select Fund have the same
investment advisor and, therefore, are considered to be affiliated. The Manager
serves as investment advisor to the Select Fund and receives from the Select
Fund an annualized fee equal to 0.10% of the Select Fund's average daily net
assets. During the six months ended June 30, 2007, fees earned by the Manager
from the Select Fund were $469.

     Interfund Lending Program

          Pursuant to an exemptive order by the SEC, the Fund, along with other
registered investment companies having management contracts with the Manager,
may participate in an interfund lending program as a borrower. This program
provides an alternative credit facility allowing the Fund to borrow from other
participating Funds. For the six months ended June 30, 2007, the Fund did not
utilize the credit facility.

     Reimbursement of Expenses

          The Manager agreed to reimburse the Fund to the extent that total
annual fund operating expenses exceed the Fund's expense cap. For the period
ended June 30, 2007, the Manager waived or reimbursed expenses of $13,589.

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 or excise tax provision is required.

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

          The tax character of distributions paid during the six months ended
June 30, 2007 and the 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 as follows (in thousands):


                                                           
Cost basis of investments for federal income tax purposes...  $38,888
Unrealized appreciation.....................................        8
Unrealized depreciation.....................................     (819)

Net unrealized appreciation/(depreciation)..................     (811)

Undistributed long-term gain/(loss).........................   (1,373)

                                                              =======


          Financial reporting records are adjusted for permanent book/tax
differences to reflect tax character. Financial records are not adjusted for
temporary differences. The temporary differences between financial reporting and
tax-basis reporting of unrealized appreciation/(depreciation) are attributable
primarily to the tax deferral of losses from wash sales and current recognition
of unrealized appreciation/(depreciation) on open foreign currency transactions.

          Due to inherent differences in the recognition of income, expenses and
realized gains/(losses) under U.S. generally accepted accounting principles and
federal income tax regulations, permanent differences between book and tax
reporting have been identified and appropriately reclassified on the Statement
of Assets and Liabilities.

DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE MANAGEMENT AGREEMENT
AND INVESTMENT ADVISORY AGREEMENTS OF THE FUND
(UNAUDITED)

INTERIM RENEWAL

          In prior years, the Board of Trustees ("Board" or "Trustees")
typically has considered the annual renewal of the existing Management Agreement
between American Beacon Advisors, Inc. (the "Manager") and the American Beacon
Funds (the "Trust"), on behalf of the Treasury Inflation Protected Securities
Fund (the "Fund"), and each Investment Advisory Agreement between the Manager
and a sub-advisor at the Board meeting held in the first quarter of each year.
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 and Investment Advisory
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
and Investment Advisory Agreements, 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 and Investment Advisory
Agreements on an interim basis, the Trustees considered the best interests of
the Fund. The following considerations and conclusions are applicable to the
Fund.

Cost of Services. The Board considered that the fee rate schedules for the
Manager and the sub-advisors had not changed since the last contract renewal.
The Board considered that, in many cases, the Manager has negotiated the lowest
sub-advisory fee a sub-advisor charges for any comparable client accounts.

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. Additionally, the
Manager allocates the assets of the Fund among the Fund's sub-advisors, and
monitors and evaluates the performance of the sub-advisors. Based on this
information, the Board concluded that the nature, extent and quality of the
management and advisory services provided by the Manager and each sub-advisor
were appropriate for the Fund and, thus, supported a decision to renew the
Management and each Investment Advisory 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.

          Based on, among others, these considerations and those noted above,
the Trustees determined that the Fund and its shareholders would benefit from
the Manager's and the sub-advisors' continued management of the Fund until the
next regular Board meeting and approved the renewal of the Agreements 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
existing Management Agreement between the Manager and the Fund and each
Investment Advisory Agreement between the Manager and a subadvisor. In
preparation for the Board's consideration to renew these Agreements, the Board
and its Investment Committee undertook steps to gather and consider information
furnished by the Manager, the subadvisors and Lipper, Inc. ("Lipper"). The
Board, with the assistance of independent legal counsel, requested and received
certain relevant information from the Manager and each subadvisor.

AND INVESTMENT ADVISORY AGREEMENTS OF THE FUND
(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 and the
subadvisors to inquiries requesting:

     -    a description of the scope of portfolio management services provided
          to the Fund and the firm's other clients, including other registered

          or disadvantages that might accrue to the Fund due to the firm's
          involvement in other activities;

     -    a description of the personnel who are assigned primary responsibility
          for managing the Fund, including any changes during the past year, and

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

          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 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 and
Investment Advisory 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 SERIES OF THE TRUST

          In determining whether to approve the continuance of the Management
Agreement and each Investment Advisory Agreement, the Trustees considered the
best interests of the Fund separately from the other series of the Trust. In
addition, while the Management Agreement and the Investment Advisory Agreements
for the Fund were considered at the same Board meeting, the Board considered the
Fund's investment management and subadvisory 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 or subadvisor's cost
for providing the services and the profitability of the advisory business to the
Manager or subadvisor; (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 or a subadvisor or their affiliates
with other clients (such as pension funds and other institutional funds); and
(7) any other benefits derived or anticipated to be derived by the Manager or a
subadvisor from their relationship with a Fund. The Trustees posed questions to
various management personnel of the Manager regarding certain key aspects of the
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 Trust's' product line; the Manager's
record in building improved compliance, control and credit functions that reduce
risks to the Trust; the addition of personnel to manage the series of the Trust,
promote sales and improve services, including the addition of a separate new
information technology (IT) department at the Manager; the high rankings
received by the Trust in service surveys; and the active role played by the
Manager in monitoring and, as appropriate, recommending replacements for the
investment subadvisors.

          With respect to the renewal of the Investment Advisory Agreements, the
Trustees considered the background and experience of each subadvisor's
investment personnel responsible for managing series of the Trust, the size of
the subadvisor and their ability to continue to attract and retain qualified
investment personnel.

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

Investment Performance. The Board evaluated the comparative information provided
by Lipper and the Manager regarding investment performance by each series of the
Trust 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 Manager also
noted that it generally was satisfied with the performance of the subadvisors. A
discussion regarding the Board's considerations with respect to the Fund's
performance appears below under "Additional Considerations and Conclusions with
Respect to the Fund."

Cost of Services and Profits Realized. In analyzing the cost of services and
profitability of the Manager and a subadvisor by series, the Board considered
the revenues earned and the expenses incurred by the Manager and those
subadvisors that provided such data. The profitability levels were noted at both
an individual series level and at an aggregate level for all series of the
Trust.

          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 further considered that each sub-advised
series pays the Manager the amounts due to its subadvisors, and the Manager
remits these amounts directly to the applicable subadvisors. The Board
considered that the Manager receives service and administrative fees to
compensate the Manager for providing administrative services to the Trust and to
compensate third-party administrators and broker-dealers for services to Trust
shareholders. In addition, the Board considered that the Manager receives
management fees for overseeing the securities lending relationships on behalf of
various series of the Trust.

          In analyzing the cost of services and profitability of each subadvisor
in connection with its investment advisory services to a series, the Board
considered that, in many cases, the Manager has negotiated the lowest
subadvisory fee a subadvisor charges for any comparable client accounts. The
Board gave less weight to profitability considerations or did not view this data
as imperative to its deliberations given the arm's-length


                                       19

<PG$PCN,022000000>

AND INVESTMENT ADVISORY AGREEMENTS OF THE FUND
(UNAUDITED)

nature of the relationship between the Manager and the subadvisors with respect
to the negotiation of subadvisory fees.

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

Economies of Scale. In considering the reasonableness of the management and
investment advisory fees, the Board considered whether economies of scale will
be realized as each series of the Trust grows and whether fee levels reflect
these economies of scale for the benefit of Trust shareholders. In this regard,
the Board considered that the Manager has negotiated breakpoints in the
subadvisory fee rates. The Board also noted, for purposes of determining the fee
rates chargeable to the Trust, many subadvisors have agreed to take into account
other assets of AMR Corporation and its pension plans that are managed by the
subadvisors. Thus, many series of the Trust are able to receive lower effective
fee rates. This fee arrangement also benefits AMR Corporation and its pension
plans. The Board also noted that the Trust had experienced substantial recent
asset growth.

          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 and subadvisor fee schedules provide for a reasonable sharing of
benefits from any economies of scale with each series of the Trust.

BENEFITS DERIVED FROM THE RELATIONSHIP WITH THE TRUST. The Board considered the
"fall-out" or ancillary benefits that accrue to the Manager and/or the
subadvisors as a result of the advisory relationships with the Trust, including
greater exposure in the marketplace with respect to the Manager's or
subadvisor's investment process and expanding the level of assets under
management by the Manager and the subadvisors. In addition, the Board noted that
the Manager provides services to the Trust at a relatively low cost, and the
benefit plans of AMR Corporation have invested a substantial number of assets in
the Trust, which helps reduce costs. The Board also considered that certain of
the subadvisors reimburse the Manager for certain of its costs relating to
distribution activities for the Trust.

          Based on the foregoing information, the Board concluded that the
potential benefits accruing to the Manager and the subadvisors by virtue of
their relationships with the Trust appear to be fair and reasonable.

ADDITIONAL CONSIDERATIONS AND CONCLUSIONS WITH RESPECT TO THE FUND

          The performance comparisons below were made versus the Fund's Lipper
peer universe median. 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.

          In considering the renewal of the Management Agreement with respect to
the Fund, the Trustees considered the following additional factors: (1) the Fund
outperformed its peer universe median for the one- and two-year periods; (2) the
Manager's explanation regarding the limitations of Lipper's methodology on the
selection of a particular peer group for the Fund; (3) the actual management fee
(including administrative fees) and the total expense ratio of the Institutional
Class of Fund shares was lower than its Lipper expense group median; (4) the
Manager's explanation that the Lipper data does not reflect the imposition of a
more recent fee waiver for the Fund; and (5) the Manager contractually agreed to
continue to waive fees and/or

AND INVESTMENT ADVISORY AGREEMENTS OF THE FUND

reimburse expenses to the extent necessary to maintain a competitive total
expense ratio for the Fund's Institutional Class.

          In considering the renewal of the Investment Advisory Agreements with
Brown Brothers Harriman & Co. ("BBH") and NISA Investment Advisors LLC ("NISA"),
the Trustees considered the following additional factors: (1) BBH and NISA each
outperformed the peer universe median for the one- and two-year periods; (2) BBH
underperformed its market benchmark index with respect to its allocated portion
of the Fund's assets for the one-year period ended December 31, 2006; (3) NISA
outperformed its market benchmark index with respect to its allocated portion of
the Fund's assets for the 2006 and 2005 calendar years; (4) the fee schedules of
each subadvisor include breakpoints, which reduce fee rates as the assets of the
Fund increase; (5) each subadvisor also represented that it does not charge a
lower advisory fee to any other comparable clients; and (6) the Manager's
recommendation to continue to retain each subadvisor.

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

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.

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
U.S. Government Money Market Average is calculated by taking an arithmetic
average of the returns of the mutual funds in the Lipper Institutional U.S.
Government 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    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.

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.

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):

*    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.

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.

(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

          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

          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"

          broker-dealers;

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

     -    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

          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.

AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS - CONTINUED
(UNAUDITED)

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.
