DOMESTIC MARKET OVERVIEW

June 30, 2006 (Unaudited)
- --------------------------------------------------------------------------------

The U.S. economy entered 2006, its fifth consecutive year of expansion, with an
impressive first three months. Equity markets trumped the preceding quarter's
gains, delivering the best first quarter in several years. The second quarter of
2006 was a difficult period for investors, with most equity markets posting
losses. As was the case in the first quarter, market volatility continued
throughout the second quarter, but this time leaning in a negative direction.
Profit taking and concerns over the medium-term strength of the economy weighed
on stock prices. Moreover, equity markets came under pressure from the
intensifying headwinds of higher interest rates, inflation on the upswing, a
weakening in personal consumption and the housing market, record energy prices
and ongoing unease about the excessive levels of consumer debt, all of which had
been present for some time.

     The impetus behind the U.S. market climb in the first quarter was a robust
U.S. economy, which rebounded sharply following the pause in the last quarter of
2005. Economic growth resiliently forged ahead despite well-publicized headwinds
such as rising interest rates, a slowdown in the housing market and wild cards
such as bird flu, turbulence in the Middle East and volatile energy markets.
Following solid returns in January, equity markets cooled in February. Consumer
spending slowed to the weakest pace in six months and incomes grew at the
slowest rate since November of 2005. Nonetheless, an improvement in the trade
deficit in February was a positive indicator of an ongoing economic recovery
during the first quarter. In March, consumer confidence edged higher, spurred by
rising wages and a jobless rate near a four-year low. However, retail sales
experienced its slowest growth in more than a year in March, as cold weather and
higher gasoline prices limited spending. Manufacturing growth also moderated in
March as prices rose. On the encouraging side, the unemployment rate in March
dropped to 4.7% from 4.8% in the previous month, matching a four-year low and
capping the best first quarter for hiring since 2000.

     A vigorous economy extended into April as markets opened the second quarter
in the same way the first quarter ended, posting impressive gains. By early May,
the Dow Jones Industrial Average climbed to within 100 points of its all-time
high. During the month, U.S. equity markets continued to weather the headwinds
of multi-year record prices for commodities, increasing interest rates, poorer
consumption and residential investment, and escalating geopolitical tensions.
Notable financial news for April included the yield on the bellwether 10-year
U.S. Treasury moving above the 5% mark for the first time in almost four years,
oil prices breaking the $75 per barrel mark to reach all-time highs, and gold
prices surging to a 25-year peak at above $650 per ounce.

     In May, the unemployment rate progressed from 4.7% in April to 4.6%, the
lowest level since the summer of 2001. However, equity markets lost ground
during the month amid concerns of moderating economic growth, mostly due to
weaker trends in housing and personal consumption. Consumer confidence, which
had struck a four-year high in April, dipped in May to the lowest level since
September of 2005. Furthermore, the core rate of inflation (excluding food and
energy prices) edged upward 0.3% in May, compared to the more modest gain of
0.1% in April. As widely expected, the U.S. Federal Reserve (the Fed) carried
out its 16th consecutive 0.25% hike on May 10, boosting the short-term interest
rate to 5%, the highest mark in more than five years.

     Following the Fed's rate hike in May, equity markets came under a
correction via a significant sell off, driven by interest rate concerns and a
resurgence in inflation fears, as well as the likelihood of subdued corporate
earnings growth for the second half of the year. For June, equity markets ended
the month flat, as signs of moderating economic growth mounted amid a worsening
slide in consumer senti-

ment and the housing market. Interest rates on 30-year home mortgages reached a
four-year peak. However, the unemployment rate remained at 4.6%.

     In June, the Fed carried out its 17th consecutive 0.25% hike to 5.25%. The
accompanying statement by the Fed, which omitted the phrase "the committee
judges that some further tightening may yet be needed," led many to believe that
the current cycle of interest rate hikes may be close to an end. The Fed noted
that recent indicators suggested that "economic growth is moderating from its
quite strong pace earlier this year, partly reflecting a gradual cooling of the
housing market and the lagged effects of increases in interest rates and energy
prices." Furthermore, the Fed's statement included the phrase "readings on core
inflation have been elevated in recent months," stoking investor worries over
inflation. Yet, the structural forces that have kept a lid on prices over the
past several years were still intact as of quarter-end: globalization,
competition and a technology-driven surge in productivity.

    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.

     Eight out of ten sectors in the S&P 500 Index (the "Index") had positive
returns for the first six months of 2006. The strongest performing sectors were
Telecommunication Services and Energy, each up 13.8% during this period. No
other S&P sectors achieved anything close to double digits. The weakest sector
in the first half of 2006 was Information Technology, which tumbled 5.9%. The
only other sector in the red on a year-to-date basis was Health Care, which
declined 4.2% over the period. The best overall performers in the Index for the
six-month period were Allegheny Technologies, up 92.6%, Archer-Daniels-Midland,
up 68.3% and Nucor, which gained 65.6%. The worst performers for the same time
period were Dana Corp., down 62.1%, KB HOME, down 36.4% and Goodyear Tire &
Rubber, down 36.1%.


     As of June 30, 2006, the Fund's largest sector weightings were Financials
(21.4% of assets), Information Technology (14.6% of assets), and Health Care
(12.2% of assets), consistent with the top sector weightings in the Index.


     The investment manager continues to utilize a replication strategy, 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.

2.  The Lipper Small-Cap Core Funds Index tracks 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 Index
    is an unmanaged index comprised of approximately 2,000
    smaller-capitalization stocks from various industrial sectors. One cannot
    invest directly in an index.

     All 12 sectors in the Russell 2000 Index ("Index") posted positive returns
for the semi-annual period. The top-performing sector was Materials and
Processing, returning an impressive 17.5%, followed by Other Energy and
Utilities up 15.7% and 15.2%, respectively. The worst-performing sector for the
six-month period was Health Care, with a return of only 0.4%, followed by
Consumer Discretionary (up 2.4%) and Technology (up 5.3%).

     The top individual performers in the Index for the first half of the year
were Medifast, Inc. (up 241.0%), Zoltek Cos. (up 240.4%), and Insteel Industries
(up 192.9%). The bottom performers were Neurocrine Biosciences, Inc. (down
83.1%), Anadys Pharmaceuticals (down 66.8%), and PortalPlayer, Inc. (down
65.4%).

     As of June 30, 2006, the Fund's largest sector weightings were Financial
Services (23.5% of assets), Consumer Discretionary (19.1% of assets), Technology
(13.6% of assets), and Health Care (11.7% of assets), consistent with the top
sector weightings in the Index.

     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, 2006 (Unaudited)
- --------------------------------------------------------------------------------

International equity markets generated positive performance over the semi-annual
period ended June 30, 2006 as European economic growth continued to strengthen.
During the reporting period, international equity markets outperformed U.S.
equity markets.

     As evidence mounted of moderating economic growth elsewhere, the euro zone
continued to demonstrate resilience. European companies were the leaders in
analysts' upgrades. Both business and consumer confidence hit five-year highs
during the second quarter. Government reports and industry surveys showed
accelerating economic growth across the region, as increased exports spurred
investment and hiring.

     All 16 of the MSCI Europe country indexes posted positive returns for the
semi-annual period, with a majority exceeding the MSCI Europe's 13.6% gain.
Norway (22.7%), Portugal (21.8%), and Spain (16.5%) were the leading regional
performers, respectively; at the other end of the spectrum were Switzerland and
Denmark (10.0% each), the Netherlands (10.7%), and Austria (11.1%).

     March was the most eventful month of the first quarter for Europe in terms
of financial news. Early in the month, the European Central Bank (ECB) raised
interest rates by 0.25% to 2.5%, following December's first hike in five years.
Consumer confidence in the regional economy rose to the highest level in almost
five years as export revenue sparked domestic spending. June was the most
eventful month of the second quarter for Europe in terms of financial news.
Early in the month, in an effort to counter inflation, which had edged up to
2.5% in May from 2.4% in April, the ECB raised interest rates by 0.25% to 2.75%.
In Germany, the region's largest economy, business confidence reached an
all-time high since the country's reunification in 1991. The German economy is
estimated to have expanded at the fastest pace in more than five years in the
second quarter, at 0.7%, led by construction and industrial output. In addition,
unemployment improved for a third straight month to its best level since 2004.

     The Asia/Pacific Basin region was a laggard among the developed regions,
with the MSCI Pacific Index posting only 3.5% for the semi-annual period. In the
Asia/Pacific Basin region, Singapore posted the strongest gain over the period
with 11.4%. Japan posted positive, but relatively weak, returns of 1.9% over the
same timeframe. New Zealand was the only country of the developed MSCI country
indexes that ended in negative territory for the period (-11.6%). In Singapore,
gross domestic product expanded for a fourth straight quarter, at a 1.2%
annualized pace in the first quarter. This expansion followed a 12.5% increase
in the previous quarter and added to evidence that global demand for digital
music players and laptop computers manufactured in Asia was fueling regional
growth. In Japan, stocks suffered mainly from the likelihood of the first
interest rate increase in more than 10 years. Of 33 industry groups in the Topix
Index, brokerages -- such as Nomura Holdings, the nation's largest securities
firm -- posted the steepest losses.

     Turning to global currencies, the major currencies traded in relatively
narrow ranges over the course of the first quarter. The U.S. dollar, which
outperformed most major currencies in 2005, gained 2.6% against the euro, rose
1.0% with respect to the pound, and ended flat versus the yen. In the second
quarter, the U.S. dollar continued its out-performance against most major
currencies, registering gains of 5.7%, 6.6%, and 3.2% against the euro, pound,
and yen, respectively.

FUND EXPENSES
June 30, 2006 (Unaudited)
- --------------------------------------------------------------------------------

FUND EXPENSE EXAMPLE

     As a shareholder of a Fund, you incur two types of costs: (1) transaction
costs, including redemption fees if applicable, 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 in each Class and held for the entire period from January 1, 2006
through June 30, 2006.

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 PlanAhead and Institutional
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.

</Table>

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
PlanAhead and Institutional Classes 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 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"
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.

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.

     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.

     American Beacon Advisors, Inc. (the "Manager") is a wholly-owned subsidiary
of AMR Corporation, the parent company of American Airlines, Inc. ("American"),
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

     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
between the classes:

<Table>
<Caption>
CLASS:                                       OFFERED TO:                                     SERVICE FEES:

</Table>

     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.

  Valuation of Investments

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

AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS -- CONTINUED
June 30, 2006 (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 and orders accepted or upon receipt of a redemption request. 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 investment 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 reported amounts in the financial statements. Actual
results could differ from those estimates.

  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
that obligates the Manager to provide or oversee administrative and management
services to each Fund. As compensa-

                                        14


AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS -- CONTINUED
June 30, 2006 (Unaudited)
- --------------------------------------------------------------------------------

tion 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 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 Agreement

     The Manager and the Trust entered into a Service Agreement that obligates
the Manager to oversee additional shareholder servicing of the PlanAhead Class
of the S&P 500 Index Fund. As compensation for performing the duties required
under the Service Agreement, 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.

  Other

     Certain officers or Trustees of the Trust are also current or former
officers or employees of the Manager or American. The Trust makes no direct
payments to its officers. Mr. Feld and the non-interested Trustees (other than
Mr. O'Sullivan) and their spouses are provided free unlimited air transportation
on American. Retired Trustees and their spouses are provided free transportation
on American, up to a maximum annual value of $40,000. The Trust compensates each
Trustee with payments in an amount equal to the Trustee's income tax on the
value of this free airline travel. Mr. O'Sullivan, as a retiree of American,
already receives flight benefits. This Trustee receives an annual retainer plus
a fee for each Board meeting attended.

     At June 30, 2006, the employee benefit plans of AMR Corporation and its
subsidiary companies owned 77.5% of the Institutional Class of the S&P 500 Index
Fund, 99.2% of the Small Cap Index Fund and 80.0% 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 tax provision is required.

     Dividends are determined 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.

STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
June 30, 2006 (Unaudited)
- --------------------------------------------------------------------------------

1.   ORGANIZATION

     The 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
six 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, 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, 2006,
only the Portfolio and State Street Money Market Portfolio were in operation.
The Portfolio is authorized to issue an unlimited number of non-transferable
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. 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.

- --------------------------------------------------------------------------------

                                        32


STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS -- CONTINUED
June 30, 2006 (Unaudited)
- --------------------------------------------------------------------------------

     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.

  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 (the "SEC") 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, 2006, purchases and sales of investment
securities, excluding short-term investments, futures contracts, and in-kind
withdrawals, aggregated to $94,209,892 and $139,808,353, respectively. The
aggregate value of in-kind withdrawals was $0.

     At June 30, 2006, the book cost of investments was $1,693,252,723 which

MASTER SMALL CAP INDEX SERIES
NOTES TO FINANCIAL STATEMENTS
June 30, 2006 (Unaudited)
- --------------------------------------------------------------------------------

1.   SIGNIFICANT ACCOUNTING POLICIES:

     Master Small Cap Index Series (the "Series"), a non-diversified investment
company, is part of Quantitative Master Series Trust (the "Trust"). The Trust is
registered under the Investment Company Act of 1940, as amended, and is
organized as a Delaware statutory trust. The Declaration of Trust permits the
Trustees to issue nontransferable interests in the Trust, subject to certain
limitations. 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 National 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 Trustees of the Trust. Long
positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap 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
Trustees of the Trust. 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 are valued at the last sale price in the case of
exchange-traded options or, in the case of options traded in the OTC market, the
last asked price. Options purchased are valued at their last sale price in the
case of exchange-traded options or, in the case of options traded in the OTC
market, the last bid price. 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.
Obligations with remaining maturities of 60 days or less are valued at amortized
cost unless the Investment Adviser believes that this method no longer produces
fair valuations. Valuation of other short-term investment vehicles is generally
based on 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 Trustees of the Trust, 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 Trust under the general supervision by the Board of
Trustees of the Trust. Such valuations and procedures will be reviewed
periodically by the Board of Trustees of the Trust.

- --------------------------------------------------------------------------------

     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 also are generally determined prior to 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 may be valued at their fair value as determined in good faith by the
Board of Trustees of the Trust or by the Investment Adviser using a pricing
service and/or procedures approved by the Board of Trustees of the Trust.

  (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.

     - Financial futures contracts - The Series may purchase or sell financial
       futures contracts and options on such futures contracts. 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.

2.   INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

     The Trust has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"),an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML &
Co."), which is the limited partner.

     FAM is responsible for the management of the Series' portfolio 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. FAM 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. FAM reimbursed the Series for the amount
of $92.

     Merrill Lynch Trust Company ("MLTC"), an indirect, wholly-owned subsidiary
of ML & Co, is the Series' custodian.

     The Trust 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"), an affiliate of FAM, or its affiliates.
As of June 30, 2006, the Series lent securities with a value of $92,016 to
MLPF&S or its affiliates. Pursuant to that order, the Trust also has retained
Merrill

Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the
securities lending agent for a fee based on a share of the returns on investment
of cash collateral. MLIM, LLC may, on behalf of the Trust and the Series, invest
cash collateral received by the Series for such loans, among other things, in a
private investment company managed by MLIM, LLC or in registered money market
funds advised by Merrill Lynch Investment Managers, L.P. ("MLIM"), an affiliate
of FAM. For the six months ended June 30, 2006, MLIM, LLC received $79,192 in
securities lending agent fees.

     In addition, MLPF&S received $208 in commissions on the execution of
portfolio security transactions for the Series for the six months ended June 30,
2006.

     For the six months ended June 30, 2006, the Series reimbursed FAM $3,808
for certain accounting services.

     Certain officers and/or trustees of the Trust are officers and/or directors
of FAM, PSI, MLTC, ML & Co., MLIM, and/or MLIM, LLC.

     In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to
contribute ML & Co.'s investment management business, including FAM, to the
investment management business of BlackRock, Inc. The transaction is expected to
close at the end of the third quarter of 2006.

3.   INVESTMENTS:

     Purchases and sales (including in-kind redemptions) of investments,
excluding short-term securities, for the six months ended June 30, 2006 were
$193,153,094 and $126,684,470, respectively.

4.   SHORT-TERM BORROWINGS:

     The Trust, on behalf of the Series, along with certain other funds managed
by FAM and its affiliates, is a party to a $500,000,000 credit agreement with a
group of lenders, which expires November 2006. 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 .07% 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 Series' election, the
federal funds rate plus .50% 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, 2006.

MASTER INTERNATIONAL INDEX SERIES
NOTES TO FINANCIAL STATEMENTS
June 30, 2006 (Unaudited)
- --------------------------------------------------------------------------------

1.   SIGNIFICANT ACCOUNTING POLICIES:

     Master International Index Series (the "Series"), a non-diversified
investment company, is part of Quantitative Master Series Trust (the "Trust").
The Trust is registered under the Investment Company Act of 1940, as amended,
and is organized as a Delaware statutory trust. The Declaration of Trust permits
the Trustees to issue nontransferable interests in the Series, subject to
certain limitations. 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 National 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 Trustees of the Trust. Long
positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap 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
Trustees of the Trust. 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 are valued at the last sale price in the case of
exchange-traded options or, in the case of options traded in the OTC market, the
last asked price. Options purchased are valued at their last sale price in the
case of exchange-traded options or, in the case of options traded in the OTC
market, the last bid price. Swap agreements and forward foreign exchange
contracts are valued daily 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. Obligations with remaining
maturities of 60 days or less are valued at amortized cost unless the Investment
Adviser believes that this method no longer produces fair valuations. Valuation
of other 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 Trustees of the Trust, 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 Trust's Board
of Trustees. Such valuations and procedures will be reviewed periodically by the
Board of Trustees of the Trust.

     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

securities used in computing the net assets of the Series are determined as of
such times. Foreign currency exchange rates also are generally determined prior
to 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 may be valued at their fair value as determined in
good faith by the Trust's Board of Trustees or by the Investment Adviser using a
pricing service and/or procedures approved by the Trust's Board of Trustees.

  (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 or
if the counterparty does not perform under the contract.

     - Financial futures contracts - The Series may purchase or sell financial
       futures contracts and options on such futures contracts. 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

MASTER INTERNATIONAL INDEX SERIES

- --------------------------------------------------------------------------------

       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 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.

     FAM is responsible for the management of the Series' portfolio 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. FAM 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. For the six months ended June 30, 2006,
FAM reimbursed the Series in the amount of $1,502.

     In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated, an
affiliate of FAM, received $16,197 in commissions on the execution of portfolio
security transactions for the Series for the six months ended June 30, 2006.

     For the six months ended June 30, 2006, the Series reimbursed FAM $3,935
for certain accounting services.

     Certain officers and/or trustees of the Series are officers and/or
directors of FAM, PSI, and/or ML & Co.

     In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to
contribute ML & Co.'s investment management business, including FAM, to the
investment management business of BlackRock, Inc. The transaction is expected to
close at the end of the third quarter of 2006.

3.   INVESTMENTS:

     Purchases and sales (including in-kind redemptions) of investments,
excluding short-term securities, for the six months ended June 30, 2006 were
$182,814,349 and $115,477,218, respectively.

4.   COMMITMENTS:

     At June 30, 2006, the Series had entered into foreign exchange contracts,
in addition to the contracts listed on the Schedule of Investments, under which
it had agreed to buy various foreign currencies with an approximate value of
$24,000.

5.   SHORT-TERM BORROWINGS:

     The Trust, on behalf of the Series, along with certain other funds managed
by FAM and its affiliates, is a party to a $500,000,000 credit agreement with a
group of lenders, which expires November 2006. 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 .07% 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 Series' election, the
federal funds rate plus .50% 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, 2006.

DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE
MANAGEMENT AGREEMENT OF THE FUNDS
(Unaudited)
- --------------------------------------------------------------------------------
     At its February 17, 2006 meeting, the Board of Trustees (the "Board")
considered the renewal of the existing Management Agreement (the "Agreement")
between the Manager and the American Beacon Funds (the "Funds"), on behalf of
the American Beacon International Equity Index Fund, American Beacon S&P 500
Index Fund, and the American Beacon Small Cap Index Fund. In preparation for the
Board's consideration to renew the 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 separate meetings
on December 8, 2005, February 8, 2006 and February 17, 2006 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 Board 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 most recent audited or unaudited financial
       statements as well as Parts I and II of its Form ADV;

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

     - a cost/profitability analysis of the Manager and any actual or
       anticipated economies of scale in relation to the services it provides to
       the Funds, if available;

     - 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 any 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 it 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, including whether such services differ from the services
       provided to other clients, including other registered investment
       companies;

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

     - 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;

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

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

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

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

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

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

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

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

     - a comparison of the performance of each Fund to appropriate indices,
       including comments on the relative performance of each Fund versus
       comparable indices;

     - a discussion, if applicable, of any underperformance by a Fund relative
       to its peer group;

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

     - a description of the Manager's securities lending practices and the fees
       received from such practices;

       execution for the Funds, other special compensation, including any
       payment for order flow; 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
Institutional Class because it has the longest performance history. 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 Agreement. This
memorandum explained the regulatory requirements surrounding the Board's 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 February 2006 meeting. The Board did not identify any particular
information that was most relevant to its consideration to renew the 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 Agreement, the
Board considered the best interests of each Fund separately. In addition, while
the Agreement for all of the Funds was considered at the same Board meeting, the
Board considered each Fund's investment management relationship 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; and (5) whether fee levels reflect these economies
of scale for the benefit of Fund investors. The Trustees posed questions to
- --------------------------------------------------------------------------------
                                        65

DISCLOSURE REGARDING THE BOARD OF TRUSTEES' APPROVAL OF THE
MANAGEMENT AGREEMENT OF THE FUNDS -- CONTINUED
(Unaudited)
- --------------------------------------------------------------------------------

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 Agreement, the Board considered: the
Manager's ability to retain key investment personnel and to provide consistent
performance and an active client service program; the Manager's goal to provide
consistent above average long-term performance at low cost; the continuing
efforts by the Manager to add new Funds so as to enhance the Trusts' 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; and the active role played by the
Manager in monitoring and, as appropriate, recommending replacements for the
master portfolios. Based on this 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
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. The Board also considered the performance reports and
discussions with management at Board and Committee meetings throughout the year.
Discussions regarding the Board's considerations with respect to each Fund's
performance are 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 in
connection with its investment advisory services to a Fund, the Board considered
the Manager's operations and low cost structure. 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. Discussions
regarding the Board's considerations with respect to each Fund's fee rates are
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. With respect to the management fee, the Board acknowledged the
Manager's low cost structure and the increasing costs of personnel, technology
and operations. Based on these considerations, the Board concluded that the
Funds' fee structures are reasonably designed to pass on economies of scale to
Fund shareholders.

  Benefits to be 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. After
consideration of this 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 target indices referred to below represent the respective index the
performance of which each Fund seeks to match before the deduction of Fund
expenses. Each Lipper Index includes up to the 30 largest funds in the
respective Lipper category where the Fund is classified by Lipper.

  Additional Considerations and Conclusions with Respect to the International
  Equity Index Fund

     In considering the renewal of the Agreement with the Fund, the Board
considered performance data for various periods ended December 31, 2005. In this
regard, they considered that: (1) the total return performance of the Fund was
in the 1st quintile for all relevant periods except the five-year period where
its performance was in the 2nd quintile compared to the returns of a peer group
of mutual funds identified by Lipper as having an investment objective similar
to the Fund ("Lipper Universe"); (2) the performance of the Fund's master
portfolio was higher than its target index for all relevant periods; (3) the
Fund outperformed the Lipper International Multi-Cap Core Index for all relevant
periods except the one-year period, but the Lipper Index is comprised of funds
with an active management style versus the Fund's passive management style.

     In addition, the Board considered the fees payable under the Agreement. In
this regard, they considered that: (1) the Institutional Class total expenses
and actual management fees (including administrative fees) were in the 1st
quintile compared to the expenses and fees of a peer group of similar funds
classified by Lipper ("Fee Universe") where the 1st quintile represents the
lowest fees or expenses among the group, and (2) the Manager's profitability
analysis indicated that it incurred a loss on the services it provided to the
Fund.

     Based on these considerations and those noted above with respect to all
Funds, the Board: (1) concluded that the fees paid to the Manager under the
Agreement are fair and reasonable; (2) concluded that the profits to the Manager
are reasonable in light of the quality of services provided to the Fund; (3)
determined that the Fund and its shareholders would benefit from the Manager's
continued management of the Fund; and (4) approved the renewal of the 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 Agreement with the Fund, the Board
considered performance data for various periods ended December 31, 2005. In this
regard, they considered that: (1) the total return performance of the Fund was
in the 1st quintile for all relevant periods except the five-year period where
its performance was in the 2nd quintile compared to the Lipper Universe; (2) the
Fund's master portfolio equaled the performance of its target index for the
one-, three- and five-year and since inception periods; and (3) the Fund
outperformed the Lipper S&P 500 Index Objective Index for all relevant periods.

     In addition, the Board considered the fees payable under the Agreement. In
this regard, they considered that the Institutional Class total expenses and
actual management fees (including administrative fees) were in the 1st quintile
compared to the Fee Universe where the 1st quintile represents the lowest fees
or expenses among the group.

     Based on these considerations and those noted above with respect to all
Funds, the Board: (1) concluded that the fees paid to the Manager under the
Agreement are fair and reasonable; (2) concluded that the profits to the Manager
are reasonable in light of the quality of services provided to the Fund; (3)
determined that the Fund and its shareholders would benefit from the Manager's
continued management of the Fund; and (4) approved the renewal of the Agreement
with respect to the Fund.

  Additional Considerations and Conclusions with Respect to the Small Cap Index
  Fund

     In considering the renewal of the Agreement with the Fund, the Board
considered performance data for various periods ended December 31, 2005. In this
regard, they considered that: (1) the total return performance of the Fund was
in the 2nd quintile for the three-year period, the 3rd quintile for the one-,
four-and five-year periods and the 4th quintile for the two-year period compared
to the Lipper Universe; (2) the Fund's master portfolio equaled or outperformed
the performance of its target index for the one-, three- and five-year and since
inception periods; and (3) the Fund underperformed the Lipper Small-Cap Core
Index for all relevant periods except the three-year period, but the Lipper
Index is comprised of funds with an active management style versus the Fund's
passive management style.

     In addition, the Board considered the fees payable under the Agreement. In
this regard, they considered that: (1) the Institutional Class total expenses
and actual management fees (including administrative fees) were in the 1st
quintile compared to the Fee Universe where the 1st quintile represents the
lowest fees or expenses among the group, and (2) the Manager's profitability
analysis indicated that it incurred a loss on the services it provided to the
Fund.

     Based on these considerations and those noted above with respect to all
Funds, the Board: (1) concluded that the fees paid to the Manager under the
Agreement are fair and reasonable; (2) concluded that the profits to the Manager
are reasonable in light of the quality of services provided to the Fund; (3)
determined that the Fund and its shareholders would benefit from the Manager's
continued management of the Fund; and (4) approved the renewal of the Agreement
with respect to the Fund.

FELLOW SHAREHOLDERS:

Enclosed please find the Semi-Annual Report for the American Beacon Treasury
Inflation Protected Securities Fund for the six months ended June 30, 2006.

     The Federal Reserve (the "Fed") raised overnight rates four times during
the period, resulting in a Fed Funds target rate of 5.25% as of June 30, 2006.
In its June statement, the Fed acknowledged that economic growth is moderating
but remained concerned that "the high levels of resource utilization and the
prices of energy and other commodities have the potential to sustain inflation
pressures."

     The American Beacon Treasury Inflation Protected Securities Fund realized a
slight decline of 0.21% for the six-month period, outperforming the Lipper TIPS
Index, which declined 2.16%. Looking forward, the Treasury Inflation Protected
Securities Fund will continue to seek inflation protection and income by
investing primarily in inflation-indexed debt securities.

     Please review the enclosed portfolio listings and detailed financial data.
As always, we welcome the opportunity to serve your financial needs. Should you
have any questions about the enclosed information, please do not hesitate to

MARKET OVERVIEW
JUNE 30, 2006 (UNAUDITED)

- --------------------------------------------------------------------------------


Economic data released during the first half of 2006 suggests that we have
entered a more mature phase of the business cycle where consumers take a back
seat, while the corporate sector drives the economy forward. Consumer spending
and housing activity are gradually slowing, but production activity, business
investment, and government spending are proving to be powerful engines of
growth. For the period, the year-over-year change in the Consumer Price Index
("CPI") rose from 3.4% in December 2005 to 4.3% in June 2006. Overall, continued
economic strength, hints of increased inflation expectations, and uncertainty
over the path of monetary policy all played a part in driving interest rates
higher during the period.

     In the first half of 2006, we clearly entered a period of tighter monetary
policy on a global scale. In the month of June alone, central banks in Canada,
Europe, Switzerland, Sweden, China, India, Korea, Thailand, Australia, Colombia,
South Africa, and of course the U.S. have all tightened policy. The early months
of Fed Chairman Bernanke's leadership of the Fed have brought a great deal of
uncertainty relative to the path of monetary policy tightening here in the U.S.
Early comments about a desire to "pause" were followed by tough talk on
inflation readings ("an unwelcome development"), which were followed by a dovish
communique following the June 29 Federal Open Market Committee ("FOMC") meeting.
As a direct result, the September 2006 Eurodollar futures contract, an indicator
of short term market sentiment, fluctuated across a wider than usual range in
June and break-even inflation rates (the yield differential between Treasury
inflation-protected securities ("TIPS") and nominal bonds of similar maturity)
were volatile. During the first half of the year, the Fed lifted short term
interest rates 1.00% with the Fed Funds rate settling at 5.25% on June 30, 2006.

     TIPS performance in the first half of 2006 was a good news -- bad news
story. Intermediate maturity TIPS produced a negative return for the period when
looked at in absolute terms (Lehman 1-10 Year TIPS Index at -0.09%) but managed
to deliver positive results when evaluated in relative terms (TIPS outperformed
similar maturity nominal bonds). Overall, yields on intermediate maturity TIPS
rose 0.40% to 0.50%, and the yield curve steepened marginally. The strong
relative performance of TIPS was driven by strong demand and was reflected in
rising break-even inflation rates. For the period, break-even inflation rates
for 5-year maturities rose 0.36% to close at 2.70%. The strong demand for TIPS
was directly attributable to the inflation storm clouds that had gathered
throughout the period and peaked in May. The catalysts included a classic brew
of rising utilization rates, a surge in metal and energy prices, growing
geopolitical tension, a weakening U.S. Dollar, and increased concerns about the
inflation fighting backbone of the Bernanke Fed -- all very supportive of TIPS
relative to nominal bonds. As we closed the period, 5-year and 10-year TIPS were
yielding 2.43% and 2.54%, respectively.

2.    The Lehman Bros. 1-10 Yr. U.S. TIPS Index is an unmanaged market index
      comprised of 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 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.

     The Fund underperformed the Index for the six-month period by 0.12%.
Although the Fund modestly outperformed on a gross basis, the sub-advisors'
excess returns were not sufficient to fully offset Fund expenses. The Fund
outperformed in January, underperformed in April and posted returns similar to
the Index during the other four months in the six-month period. In January, the
Fund added value by reducing its exposure to areas of the yield curve where new
supply was auctioned (10 and 20 year securities) and by overweighting the 1-8
year sector. However, in April, a steepening of the yield curve and a widening
of break-even inflation rates hurt performance as the Fund held longer maturity
TIPS and had an exposure to nominal bonds.

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

PERFORMANCE OVERVIEW
AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND(SM) -- CONTINUED
JUNE 30, 2006 (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, 2006 through June
30, 2006.

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. Shareholders of the
Institutional 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 Institutional 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.

</Table>


*     Expenses are equal to the Fund's annualized expense ratio for the six-
      month period of 0.41%, 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, 2006 (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, as
amended, as a diversified, no load, open-end management investment company. The
American Beacon Treasury Inflation Protected Securities Fund (the "Fund") is a
series of the Trust and commenced active operations on June 30, 2004. The Fund's
investment objective is to provide inflation protection and income.

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

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

  Security Valuation

     Net asset value per share is calculated as of the close of business on the
New York Stock Exchange, normally 4:00 p.m. Eastern Time.

     Debt securities (other than short-term securities) normally are valued on
the basis of prices provided by a 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. In some cases, 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.

     Securities for which the market prices are not readily available or are not
reflective of the fair value of the security, will be priced at a fair value
following procedures approved by the Board of Trustees (the "Board"). Issuer
specific events, market trends, valuations of similar securities and other
market data may be reviewed in the course of making a good faith determination
of a security's fair value. In light of the judgement involved in fair value
decisions, there can be no assurance that a fair value assigned to a particular
security is accurate.

  Security Transactions and Investment Income

     Security transactions are recorded on the trade date of the security
purchase or sale.

     Dividend income is recorded on the ex-dividend date. Interest income is
earned from settlement date, recorded on an 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.

  Dividends to Shareholders

     The Fund declares and pays dividends from net investment income quarterly.
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 into U.S.
dollars at the rate of exchange prevailing on the respective dates of such
transactions. The effect of changes in foreign currency exchange rates on
investments is separately identified from the fluctuations arising from changes
in market values of securities held and is reported with all other foreign
currency gains and losses in the Fund's Statement of Operations.

  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. Actual
results may differ from those estimated.

  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, fund management and securities lending services. Investment
assets of the Fund are managed by multiple investment advisors that 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 Fund's average
daily net assets plus amounts paid by the Manager to the investment advisors of
the Fund. During the six months ended June 30, 2006, the management fee rate,
including fees paid to investment advisors, was 22%. Total management fees were
$33,022, of which $18,072 was paid to investment advisors and $14,950 was
retained by the Manager.

  Administrative Services Agreement

     The Manager and the Trust entered into an Administrative Services Agreement
that 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 Fund

     The Fund may invest in the American Beacon Money Market Select Fund (the
"Select Fund"). 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 period, fees earned by the Manager
from the Fund's investment in the Select Fund were $406.

  Other

     Certain officers or Trustees of the Trust are also current or former
officers or employees of the Manager or American. The Trust makes no direct
payments to its officers. Mr. Feld and the non-interested Trustees (other than
Mr. O'Sullivan) and their spouses are provided unlimited air transportation on
American. Retired Trustees and their spouses are provided free transportation on
American, up to a maximum annual value of $40,000. The Trust compensates each
Trustee with payments in an amount equal to the Trustee's income tax on the
value of this free airline travel. Mr. O'Sullivan, as a retiree of American,
already receives flight benefits. Mr. O'Sullivan receives an annual retainer
plus a fee for each Board meeting attended.

  Expense Reimbursement Plan

     The Fund has adopted an expense reimbursement Plan whereby the Manager may
seek recoupment of fees waived or expenses reimbursed for a period of up to
three years. However, recoupment will only occur if the Funds' average net
assets have grown or expenses have declined sufficiently to allow recoupment
without causing its expense ratio to exceed the previously agreed upon
contractual expense limit. During the year ended December 31, 2005, due to asset
growth and a reduction of expenses in the latter part of the year, the Manager
recouped $4,096 for expenses previously waived earlier in the year and $14,537
for expenses waived during 2004.

  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. This program provides an
alternative credit facility allowing the Fund to borrow from, or lend money to,
other participating Funds. The Fund did not utilize the credit facility during
the six months ended June 30, 2006.

3.  FEDERAL INCOME AND EXCISE TAXES

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

     Dividends are determined in accordance with federal income tax regulations
that 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 during the years ended June 30, 2006 and
December 31, 2005 were as follows (in thousands):

     For the year ended June 30, 2006, the components of distributable earnings
were as follows (in thousands):


<Table>

</Table>


     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 wash sales and current recognition of unrealized
appreciation/(depreciation) on open foreign currency transactions.

     Due to the 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 without impacting the net assets of the Fund. These
differences are due primarily to the recognition of certain foreign currency
gains/(losses) as ordinary income for tax purposes.

     Accordingly, the following amounts represent current year permanent
differences that have been reclassified as of June 30, 2006 (in thousands):


<Table>

</Table>


     At June 30, 2006, the Fund had capital loss carryovers of $144,311 and
$801,330 expiring in 2013 and 2014, respectively.

4.  INVESTMENT TRANSACTIONS

     Purchases and redemptions of investments for the six months ended June 30,
2006, excluding short-term investments, were $46,045,737 and $46,128,045,
respectively. The Fund had purchases and sales of U.S. government securities of
$45,729,450 and $45,541,596, respectively.

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


     At its February 17, 2006 meeting, the Board of Trustees (the "Board")
considered the renewal of the existing Management Agreement between the Manager
and the American Beacon Funds (the "Funds") and each Investment Advisory
Agreement between the Manager and the subadvisors, on behalf of the American
Beacon Treasury Inflation Protected Securities Fund. 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. 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 separate meetings on December 8, 2005, February 8,
2006 and February 17, 2006 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 Board considered, among other materials, responses by the Manager and
the subadvisors 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 firm's most recent audited or unaudited financial
       statements as well as Parts I and II of its Form ADV;

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

     - a comparison of the performance of that portion of Fund assets managed by
       each firm with performance of other similar accounts managed by the firm,
       including a discussion of relative performance versus a peer group
       average and any remedial measures if the firm's performance was
       materially below that of the peer group;

     - a cost/profitability analysis of the firm and any actual or anticipated
       economies of scale in relation to the services it provides to the Funds,
       if available;

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

     - confirmation that the firm's financial condition does not raise concerns
       that the firm 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, including whether such services differ from the services
       provided to other clients, including other registered investment
       companies;

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

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

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

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



                                       16

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

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

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

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

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

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

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

     In addition to the foregoing, the Manager provided the following
information specific to the renewal of the Management Agreement:

     - a comparison of the performance of each Fund to appropriate indices,
       including comments on the relative performance of each subadvisor and
       each Fund versus comparable indices;

     - a discussion, if applicable, of any underperformance by a subadvisor
       relative to its peer group and whether (and if so, why) such subadvisor
       should have its contract renewed;

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

     - a table detailing the Manager's profitability with respect to each Fund;

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

     - a description of the Manager's securities lending practices and the fees
       received from such practices;

     - a description of the portfolio turnover rate and average execution costs
       for each Fund and each subadvisor to a Fund;

     - a discussion of whether the Manager receives, with respect to trade
       execution for the Funds, other special compensation, including any
       payment for order flow; 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. References below to the Treasury Inflation Protected Securities
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 Board's 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 February 2006 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.

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


CONSIDERATIONS WITH RESPECT TO ALL FUNDS

     In determining whether to approve the continuance of the Management
Agreement and each Investment Advisory Agreement, the Board considered the best
interests of each Fund separately. In addition, while the Management Agreement
and the Investment Advisory Agreements for all of the Funds were considered at
the same Board meeting, the Board considered each 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; and (5) whether fee levels reflect these
economies of scale for the benefit of Fund investors. 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 Manager's ability to retain key
investment personnel and to provide consistent performance and an active client
service program; the Manager's goal to provide consistent above average long-
term performance at low cost; the continuing efforts by the Manager to add new
series so as 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; and the active role played by the Manager in monitoring and,
as appropriate, recommending replacements for the investment subadvisors and
master portfolios. 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 subadvisor were appropriate for each Fund 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 each Fund's investment performance
relative to its benchmark index(es) and peer group. 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 the Treasury Inflation Protected Securities Fund's performance
appears below under "Additional Considerations and Conclusions with Respect to
the Treasury Inflation Protected Securities Fund."

     Cost of Services and Profits Realized.  In analyzing the cost of services
and profitability of the Manager in connection with its investment advisory
services to a Fund, the Board considered the Manager's operations and low cost
structure. 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
2005 fiscal year. The Board also noted that each sub-advised Fund 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 Funds and to compensate third-party
administrators and broker-dealers for services to Fund shareholders. In
addition, the Board considered that the Manager receives management fees for
overseeing the securities lending relationships on behalf of various Funds.

     In analyzing the cost of services and profitability of each subadvisor in
connection with its investment advisory services to a Fund, 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 arms-length nature of the relationship between
the Manager and the subadvisors with respect to the negotiation of subadvisory
fees.

     A discussion regarding the Board's considerations with respect to the
Treasury Inflation Protected Securities Fund's fee rates is set forth below
under "Additional Considerations and Conclusions with Respect to the Treasury
Inflation Protected Securities Fund."



                                       18

AND INVESTMENT ADVISORY AGREEMENTS OF THE FUND -- CONTINUED
(UNAUDITED)
- --------------------------------------------------------------------------------


     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 the Funds grow and whether fee levels reflect these
economies of scale for the benefit of Fund shareholders. In this regard, the
Board noted that, in many cases, the Manager has negotiated breakpoints in the
subadvisory fee rate. The Board also noted, where applicable, for purposes of
determining the investment advisory fee charged to the Funds, the fee schedule
to each Investment Advisory Agreement specifies that all other assets managed by
a subadvisor on behalf of AMR Corporation and its pension plans shall be
considered. Thus, the Funds are able to receive additional breakpoint benefits
resulting from the subadvisor's management of a larger pool of assets. With
respect to the management fee, the Board acknowledged the Manager's low cost
structure and the increasing costs of personnel, technology and operations.
Based on these considerations, the Board concluded that the Funds' fee
structures are reasonably designed to pass on economies of scale to Fund
shareholders.

     Benefits to be Derived from the Relationship with the Funds.  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 Funds,
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. The Board noted that the Manager
and the subadvisors may not direct the Funds' brokerage transactions to certain
brokers to obtain research and other services and that the Funds participate in
a brokerage recapture program. After consideration of this information, the
Board concluded that the potential benefits accruing to the Manager and the
subadvisors by virtue of their relationships with the Funds appear to be fair
and reasonable.

ADDITIONAL CONSIDERATIONS AND CONCLUSIONS WITH RESPECT TO THE TREASURY INFLATION
PROTECTED SECURITIES FUND

     In considering the renewal of the Management Agreement and each Investment
Advisory Agreement (collectively, the "Agreements") with the Fund, the Board
considered performance data for various periods ended December 31, 2005. In this
regard, they considered that: (1) the total return performance of the Fund was
in the 4th quintile for the one-year period compared to the returns of a peer
group of mutual funds identified by Lipper as having an investment objective
similar to the Fund; (2) the Fund's total return performance underperformed the
Lipper Treasury Inflation Protected Securities Fund Index for that same period;
(3) the portion of Fund assets allocated to Brown Brothers Harriman & Co.
("BBH") outperformed the Fund's benchmark index for all relevant periods; (4)
the portion of Fund assets allocated to NISA Investment Advisors LLC ("NISA")
underperformed the Fund's benchmark index for all relevant periods; and (5) the
Manager's explanation that the Fund's underperformance for the since-inception
period was primarily due to investment of the Fund's initial assets shortly
after a strong rally in the Treasury inflation protected securities market.

     In addition, the Board considered the fees payable under the Agreements. In
this regard, they considered that: (1) the Institutional Class total expenses
were in the 2nd quintile and actual management fees (including administrative
fees) were in the 3rd quintile compared to the expenses and fees of a peer group
of similar funds classified by Lipper where the 1st quintile represents the
lowest fees or expenses among the group; (2) BBH and NISA indicated that they do
not charge a lower fee rate for comparable client services; (3) BBH waived its
standard minimum annual fee; (4) the fee schedules of each subadvisor include
breakpoints, which reduce fee rates as the assets of the Fund increase; and (5)
the Manager's profitability analysis indicated that it incurred a loss on the
services it provided to the Fund.

     Based on these considerations and those noted above with respect to all
Funds, the Board: (1) concluded that the fees paid to the Manager and the
subadvisors under the Agreements are fair and reasonable; (2) concluded that the
profits to the Manager are reasonable in light of the quality of services
provided to the Fund, including oversight of the Fund's subadvisors; (3)
determined that the Fund and its shareholders would benefit from the Manager's
and subadvisors' continued management of the Fund; and (4) approved the renewal
of the Agreements with respect to the Fund.

FELLOW SHAREHOLDERS:

Enclosed please find the Semi-Annual Report for the American Beacon Money Market
Funds for the six months ended June 30, 2006. During this time, the Funds
outperformed their respective peer groups.

     The Federal Reserve (the "Fed") raised overnight rates four times during
the period, resulting in a Fed Funds target rate of 5.25% as of June 30, 2006.
In its June statement, the Fed acknowledged that economic growth is moderating
but remained concerned that "the high levels of resource utilization and the
prices of energy and other commodities have the potential to sustain inflation
pressures."

     Despite rising interest rates, the Cash Management Class of the American
Beacon Funds produced strong relative returns for the period. The Money Market
Fund-Cash Management Class returned 2.32% for the six months, outperforming the
Lipper Institutional Money Market Average return of 2.14%. The U.S. Government
Money Market Fund -- Cash Management Class outpaced the Lipper Institutional
U.S. Government Money Market Average with a return of 2.28% versus 2.15% for the
Average. Both Funds surpassed their respective Lipper peer groups over all time
periods.

     Please review the enclosed portfolio listings and detailed financial data.
As always, we welcome the opportunity to serve your financial needs. Should you

ECONOMIC OVERVIEW
(UNAUDITED)

- --------------------------------------------------------------------------------


The U.S. economy expanded at an annual rate of 5.6% in the first quarter of 2006
thanks to strong consumer spending and business investment. However, soaring
gasoline prices and a slowdown in the housing market caused the second quarter
gross domestic product ("GDP") growth to slow to an estimated 2.5%. It also
appeared that the labor market was cooling as payroll gains came in below
consensus, rising 325,000 during the second quarter versus a revised 629,000 in
the first quarter. Despite the slowdown in payroll growth, the unemployment rate
continued to decline during the second quarter, coming in at a low 4.6% for the
month of June. In addition, June average hourly earnings climbed 3.9% from the
prior year, fueling concerns that the low unemployment rate was putting upward
pressure on inflation.

     The Federal Reserve Board raised overnight rates by 25 percentage points at
each of the first four meetings in 2006, resulting in a Fed Funds target rate of
5.25% as of June 30, 2006. In its June statement, the Fed acknowledged that
economic growth was moderating but remained concerned that "the high levels of
resource utilization and the prices of energy and other commodities have the
potential to sustain inflation pressures." They did remove the phrase "some
further policy firming may yet be needed" and stated that the extent and timing
of any additional firming "will depend on the evolution of the outlook for both
inflation and economic growth." The Fed remains data dependent, leaving the door
open for either a pause or another rate hike at their next several meetings.


     As expected, we began to see higher energy and commodity prices being
passed on to the consumer in the form of higher goods prices during the period.
The core Consumer Price Index ("CPI") rose more than forecast in June, up 0.3%
for the month and 2.6% year over year. This was the fourth consecutive month of
core inflation rising 0.3%, which according to Bloomberg, is the longest such
stretch since January to April 1995. Fed chairman Bernanke called the recent
increases in core prices "unwelcome developments" and said central bankers "will
be vigilant" to ensure inflation doesn't become entrenched. As a result, if core
inflation numbers continue to rise in the coming months, the Fed may likely
prolong its tightening cycle. At the end of the second quarter, the Fed Funds
futures market was indicating a chance of another 0.25% rate increase by the end
of the third quarter.

     The yield curve shifted up as the Fed Funds rate rose during the second
quarter 2006. However, the curve continued to invert as yields on the 6-month
Treasury bill ended the quarter at 5.23% versus 5.15% for the 2-year note and
5.14% for the 10-year note.

PERFORMANCE OVERVIEW
AMERICAN BEACON MONEY MARKET FUND(SM)
JUNE 30, 2006 (UNAUDITED)

- --------------------------------------------------------------------------------


     The Money Market Fund maintained the strategy of purchasing 3-month
variable rate securities based on the London Interbank Offered Rate (LIBOR) in
addition to short-dated commercial paper during the period in response to the
rising interest rate environment.

     With the Fed Funds futures market indicating a chance of another 25
percentage point rate increase by the end of the third quarter, the Money Market
Fund continued to keep its weighted-average maturity relatively short. However,
we will continue to monitor economic trends and adjust our weighted-average
maturity accordingly. In addition, we remain conservative on credit risk given
the tight credit spread environment.

Management Class of the American Beacon Money Market Fund was 2.32%. The Fund
outperformed the Lipper Institutional Money Market Average return of 2.14% by 18
percentage points. Lipper Inc. ranked the Cash Management Class of the Fund 19th
among 324 and 14th among 280 Institutional Money Market Funds for the one-year
and three-year periods ended June 30, 2006, respectively(1). The Lipper

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 period represents the total
      returns achieved by the Institutional Class from 1/1/96 up to 12/1/01, the
      inception date of the Cash Management Class, and the returns of the Cash
      Management Class since its inception. 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 1/1/96.

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, 2006 through June
30, 2006.

ACTUAL EXPENSES

     The "Actual" lines of the table provide information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the "Actual" line under the heading "Expenses Paid During Period" 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, 2006 (UNAUDITED)

- --------------------------------------------------------------------------------


     The U.S. Government Money Market Fund maintained the strategy of purchasing
3-month LIBOR-based variable rate securities in addition to short-dated
commercial paper during the period in response to the rising interest rate
environment.

     With the Fed Funds futures market indicating greater than a 50% chance of
another 25 percentage point rate increase at the Fed meeting in August, the U.S.
Government Money Market Fund continued to keep its weighted-average maturity
relatively short. However, we will continue to monitor economic trends and
adjust our duration posture accordingly. In addition, we remain conservative on
credit risk given the tight credit spread environment.

     For the six months ended June 30, 2006, the total return of the Cash
Management Class of the American Beacon U.S. Government Money Market Fund was
2.28%. The Fund outperformed the Lipper Institutional U.S. Government Money
Market Average return of 2.15% by 13 percentage points. Lipper Inc. ranked the
Cash Management Class of the Fund 9th among 140, 11th among 103 and 11th among
61 Institutional U.S. Government Money Market Funds for the one-year, five-year
and ten-year periods ended June 30, 2006, respectively(1). 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.

PERFORMANCE OVERVIEW
AMERICAN BEACON MUNICIPAL MONEY MARKET FUND(SM)
JUNE 30, 2006 (UNAUDITED)

- --------------------------------------------------------------------------------



     The American Beacon Municipal Money Market Fund maintained a relatively
short average maturity in the first half of 2006. The variable rate demand note
(VRDN) market provided the most attractive investment option throughout the
period. Rates on these securities remained appealing, as short-term interest
rates were increased at seventeen consecutive Fed meetings since June 2004.

     We will continue to focus purchases on attractively priced VRDNs backed by
letters of credit or bond insurance and may buy selective fixed rate instruments
when evidence emerges that the Fed has completed its current tightening cycle.

     For the six months ended June 30, 2006, the total return of the PlanAhead
Class of the American Beacon Municipal Money Market Fund was 1.16%. The Fund
under-performed the Lipper Tax-Exempt Money Market Average return of 1.27%. The
Lipper Tax-Exempt Money Market Average is calculated by taking an arithmetic
average of the returns of the mutual funds in the Lipper Tax-Exempt 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 share 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.

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, 2006 through June
30, 2006.

JUNE 30, 2006 (UNAUDITED)

- --------------------------------------------------------------------------------


ACTUAL EXPENSES

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

AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS

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, American Beacon U.S. Government Money Market and
American Beacon Municipal Money Market Funds (each a "Fund" and collectively,
the "Funds").

     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:

Money Market Fund                                                 Money Market Portfolio
U.S. Government Money Market Fund                                 U.S. Government Money Market Portfolio
Municipal Money Market Fund                                       Municipal Money Market Portfolio
</Table>


     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 (7.83%,
4.19% and 23.84% at June 30, 2006 of the American Beacon Master Trust Money
Market, U.S. Government Money Market and Municipal 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, the parent company of American Airlines, Inc. ("American"),
and was organized in 1986 to provide business management, advisory,
administrative and asset management consulting services to the Trust and other
investors.

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

  Class Disclosure

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




CLASS                                      OFFERED TO:                         SERVICE AND DISTRIBUTION FEES:
- -----                                      -----------                         ------------------------------

                                                                                                  

CASH MANAGEMENT CLASS   Investors making an initial investment of $10       Administrative Service Fee --  0.07%
                        million for Money Market and $2 million for U.S.
                        Government Money Market, or investors investing
                        through an intermediary
INSTITUTIONAL CLASS     Investors making an initial investment of $2        Administrative Service Fee --  0.10%
                        million
PLANAHEAD CLASS         General public and investors investing through an   Administrative Service Fee --  0.10%
                        intermediary                                        Service Fee --                 0.25%
PLATINUM CLASS          Investors investing through selected financial      Administrative Service Fee --  0.65%
                        institutions (such as banks and broker-dealers)     Distribution Fee --            0.25%



  Valuation of Investments

     The Funds record their investment in the Portfolios at fair value.
Valuation of securities by the Portfolios is discussed in Note 1 of the
Portfolios' Notes to Financial Statements, which are included elsewhere in this
report.

  Investment Income and Dividends to Shareholders

     Each Fund records its share of net investment income (loss) and realized
gain (loss) in the Portfolio each day. All net investment income (loss) and
realized gain (loss) of each Portfolio are allocated pro rata among the

                                       13



AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS -- CONTINUED

- --------------------------------------------------------------------------------


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.

  Valuation of Shares

     The price per share is calculated separately for each class of each Fund on
each day on which shares are offered for sale and orders accepted or upon
receipt of a redemption request. With respect to a class of a Fund, price per
share is computed by dividing the value of the class' pro rata allocation of the
Fund's investments and other assets, less liabilities, by the number of class
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.

  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

     The Manager and the Trust entered into an Administrative Services Agreement
that obligates the Manager to provide or oversee administrative and management
services to the Funds. 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 each of the Institutional, PlanAhead
and Platinum Classes of the Funds.

     The Trust has adopted an Administrative Services Plan with respect to the
Platinum Class of the Funds. As compensation for providing administrative
services, the Manager receives an annualized fee of 0.55% of the average daily
net assets of the Platinum Class of each Fund.

     A separate Administrative Services Plan has been adopted for the Cash
Management Class of the Funds. As compensation for providing administrative

net assets of the Cash Management Class of each Fund.

  Distribution Plan

     The Trust, except for the Platinum Class of the Funds, 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.

     A separate Distribution Plan (the "Distribution Plan") has been adopted
pursuant to Rule 12b-1 under the Act for the Platinum Class of the Funds. Under
the Distribution Plan, as compensation for distribution assistance, the Manager
receives an annualized fee of 0.25% of the average daily net assets of the
Platinum class of each Fund. The fee will be payable without regard to whether
the amount of the fee is more or less than the actual expenses incurred in a
particular month by the Manager for distribution assistance.

  Service 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 Cash Management Class of
each Fund for other expenses through February 28, 2007 to the extent that total
annual fund operating expenses exceed 0.15% and 0.19% for the Money Market and
U.S. Government Money Market Funds, respectively.

     The Manager contractually agreed to reimburse the PlanAhead Class of the
Municipal Money Market Fund for other expenses through February 28, 2007 to the
extent that total annual fund operating expenses exceed 0.99%. In addition, the
Manager voluntarily agreed to reimburse the PlanAhead Class of the U.S.
Government Money Market Fund for other expenses through February 28, 2007 to the
extent that total annual fund operating expenses exceed 0.65%. Beginning June
26, 2006 the Manager voluntarily agreed to reimburse the Institutional Class of
the Money Market Fund for other expenses to the extent annualized operating
expenses exceed 0.18%.

     The Manager contractually agreed to reimburse the Platinum Class of each
Fund for distribution fees and other expenses through February 28, 2007 to the
extent that total annual fund operating expenses exceed 0.99%. During the six
months ended June 30, 2006, the Manager waived or reimbursed expenses as
follows:

three years. However, recoupment will occur only if the Class'

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

  Other

     Certain officers or Trustees of the Trust are also current or former
officers or employees of the Manager or American. The Trust makes no direct
payments to its officers. Mr. Feld and the non-interested Trustees (other than
Mr. O'Sullivan) and their spouses are provided free unlimited air transportation
on American. Retired Trustees and their spouses are provided free transportation
on American, up to a maximum annual value of $40,000. The Trust compensates each
Trustee with payments in an amount equal to the Trustee's income tax on the
value of this free airline travel. Mr. O'Sullivan, as a retiree of American,
already receives flight benefits. This Trustee receives an annual retainer plus
a fee for each Board meeting attended.

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 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 determined in accordance with federal income tax regulations
which may treat certain transactions differently than United States 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.

AMERICAN BEACON MASTER TRUST
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 2006 (UNAUDITED)

- --------------------------------------------------------------------------------


1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     American Beacon Master Trust (the "Trust"), formerly known as AMR
Investment Services 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, American
Beacon Master U.S. Government Money Market Portfolio and American Beacon Master
Municipal 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"), formerly known as AMR
Investment Services, Inc., is a wholly-owned subsidiary of AMR Corporation, the
parent company of American Airlines, Inc. ("American"), 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 and Excise 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 Portfolio's custodian bank, State
Street Bank and Trust Company, or at subcustodian banks. 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.

  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, 2006, the Money Market Portfolio
earned $79 under the credit facility. This amount is included in interest income
on the financial statements.

  Other

     Certain officers or Trustees of the Trust are also current or former
officers or employees of the Manager or American. The Trust makes no direct
payments to its officers. Mr. Feld and the non-interested Trustees (other than
Mr. O'Sullivan) and their spouses are provided free unlimited air transportation
on American. Retired Trustees and their spouses are provided free air
transportation on American, up to a maximum annual value of $40,000. The Trust
compensates each Trustee with payments in an amount equal to the Trustee's
income tax on the value of this free airline travel. Mr. O'Sullivan as a retiree
of American, already receives flight benefits. Mr. O'Sullivan receives an annual
retainer plus a fee for each Board meeting attended.

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


     At its February 17, 2006 meeting, the Board of Trustees (the "Board")
considered the renewal of the existing Management Agreements (the "Agreements")
between the Manager and the American Beacon Funds, on behalf of the American
Beacon Money Market Fund, American Beacon Municipal Money Market Fund, and the
American Beacon U.S. Government Money Market Fund (collectively, the "Funds"),
and between the Manager and the American Beacon Master Trust, on behalf of the
American Beacon Master Money Market Portfolio, American Beacon Master Municipal
Money Market Portfolio, and the American Beacon Master U.S. Government Money
Market Portfolio (collectively, the "Portfolios"). The term "Funds" is used
throughout this section to refer to both the Funds and the Portfolios. 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
separate meetings on December 8, 2005, February 8, 2006 and February 17, 2006 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 Board 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 most recent audited or unaudited financial
       statements as well as Parts I and II of its Form ADV;

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

     - a cost/profitability analysis of the Manager and any actual or
       anticipated economies of scale in relation to the services it provides to
       the Funds, if available;

     - 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 any 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 it 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, including whether such services differ from the services
       provided to other clients, including other registered investment
       companies;

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

     - 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;

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

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

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



                                       38

AGREEMENTS OF THE FUNDS AND THE PORTFOLIOS -- CONTINUED

- --------------------------------------------------------------------------------


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

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

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

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

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

     - a comparison of the performance of each Fund to appropriate indices,
       including comments on the relative performance of each Fund versus
       comparable indices;

     - a discussion, if applicable, of any underperformance by a Fund relative
       to its peer group;

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

     - a description of the Manager's securities lending practices and the fees
       received from such practices;

     - a description of the portfolio turnover rate and average execution costs
       for each Fund;

     - a discussion of whether the Manager receives, with respect to trade
       execution for the Funds, other special compensation, including any
       payment for order flow; 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 Agreements. This
memorandum explained the regulatory requirements surrounding the Board's 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 February 2006 meeting. The Board did not identify any particular
information that was most relevant to its consideration to renew the 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 Agreements, the
Board considered the best interests of each Fund separately. In addition, while
the Agreements for all of the Funds were considered at the same Board meeting,
the Board considered each Fund's investment management relationship 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; (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; and (5) whether fee levels reflect these economies of scale for the
benefit of Fund investors. The Trustees posed questions to various management
personnel of the Manager regarding certain key aspects of the material submitted
in support of the renewal.

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 the Agreements, the Board considered: the
Manager's ability to retain key investment personnel and to provide consistent
performance and an active client service program; the Manager's goal to provide
consistent above average long-term performance at low cost; the continuing
efforts by the Manager to add new Funds so as to enhance the Trusts' product
line; the Manager's record in building improved compliance, control and credit
functions that reduce risks to the Funds; and the addition of personnel to
manage the Funds, promote sales and improve services. Based on this 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 Agreements.

  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. The Board also considered the performance reports and
discussions with management at Board and Committee meetings throughout the year.
Discussions regarding the Board's considerations with respect to each Fund's
performance are 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 in
connection with its investment advisory services to a Fund, the Board considered
the Manager's operations and low cost structure. 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. Discussions
regarding the Board's considerations with respect to each Fund's fee rates are
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. With respect to the management fee, the Board acknowledged the
Manager's low cost structure and the increasing costs of personnel, technology
and operations. Based on these considerations, the Board concluded that the
Funds' fee structures are reasonably designed to pass on economies of scale to
Fund shareholders.

  Benefits to be 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. After
consideration of this 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 Board considered the relative performance of each Fund versus the
respective Lipper Average, which includes all comparable funds in the Lipper
category, and the Lipper Index, which includes up to the 30 largest funds in the
respective Lipper category where the Fund is classified by Lipper.

- --------------------------------------------------------------------------------


  Additional Considerations and Conclusions with Respect to the Money Market
  Fund

     In considering the renewal of the Agreements with the Fund, the Board
considered performance data for various periods ended December 31, 2005. In this
regard, they considered that: (1) the Institutional Class total return
performance was in the 2nd quintile for all relevant periods compared to the
returns of a peer group of mutual funds identified by Lipper as having an
investment objective similar to the Fund ("Lipper Universe"), and (2) the
Institutional Class outperformed the Lipper Institutional Money Market Average
for all relevant periods and underperformed the Lipper Institutional Money
Market Index for all relevant periods except the ten-year period.

     In addition, the Board considered the fees payable under the Agreements. In
this regard, they considered that: (1) the Institutional Class total expenses
were in the 2nd quintile and actual management fees (including administrative
fees) were in the 4th quintile compared to the expenses and fees of a peer group
of similar funds classified by Lipper ("Fee Universe") where the 1st quintile
represents the lowest fees or expenses among the group; (2) the Manager's
explanation that fee schedule "breakpoints" were not warranted due to, among
other factors, the low, base management fee (excluding administrative fees)
charged to the Fund; and (3) the Manager has contractually agreed to waive fees
and/or reimburse expenses to the extent necessary to maintain a competitive
total expense ratio for the Institutional, Cash Management, and Platinum Classes
of the Fund.

     Based on these considerations and those noted above with respect to all
Funds, the Board: (1) concluded that the fees paid to the Manager under the
Agreements are fair and reasonable; (2) concluded that the profits to the
Manager are reasonable in light of the quality of services provided to the Fund,
including direct management of the Fund's assets; (3) determined that the Fund
and its shareholders would benefit from the Manager's continued management of
the Fund; and (4) approved the renewal of the Agreements with respect to the
Fund.

  Additional Considerations and Conclusions with Respect to the Municipal Money
  Market Fund

     In considering the renewal of the Agreements with the Fund, the Board
considered performance data for various periods ended December 31, 2005. In this
regard, they considered that: (1) the PlanAhead Class total return performance
was in the 5th quintile for all relevant periods except the five-and ten-year
periods in which case its performance was in the 4th and 3rd quintile,
respectively, compared to the Lipper Universe; (2) the PlanAhead Class
underperformed the Lipper Tax Exempt Money Market Average and the Lipper Tax
Exempt Money Market Index for all relevant periods; and (3) the Manager's
explanation that the PlanAhead Class has a relatively low level of assets, which
resulted in a higher expense ratio and a negative impact on performance during
the more recent periods.

     In addition, the Board considered the fees payable under the Agreements. In
this regard, they considered that: (1) the PlanAhead Class total expenses were
in the 5th quintile and actual management fees (including administrative fees)
were in the 1st quintile compared to the Fee Universe where the 1st quintile
represents the lowest fees or expenses among the group; (2) 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; (3) the Manager
has contractually agreed to waive fees and/or reimburse expenses to the extent
necessary to maintain a competitive total expense ratio for the PlanAhead and
Platinum Classes of the Fund; and (4) the Manager's profitability analysis
indicated that it incurred a loss on the services it provided to the Fund.

     Based on these considerations and those noted above with respect to all
Funds, the Board: (1) concluded that the fees paid to the Manager under the
Agreements are fair and reasonable; (2) concluded that the profits to the
Manager are reasonable in light of the quality of services provided to the Fund,
including direct management of the Fund's assets; (3) determined that the Fund
and its shareholders would benefit from the Manager's continued management of
the Fund; and (4) approved the renewal of the Agreements with respect to the
Fund.

- --------------------------------------------------------------------------------


  Additional Considerations and Conclusions with Respect to the U.S. Government
  Money Market Fund

     In considering the renewal of the Agreements with the Fund, the Board
considered performance data for various periods ended December 31, 2005. In this
regard, they considered that: (1) the Cash Management Class total return
performance was in the 1st quintile for all relevant periods compared to the
Lipper Universe, and (2) the Cash Management Class outperformed the Lipper
Institutional U.S. Government Money Market Average and the Lipper Institutional
U.S. Government Money Market Index for all relevant periods.

     In addition, the Board considered the fees payable under the Agreements. In
this regard, they considered that: (1) the Cash Management Class actual
management fees (including administrative fees) and total expenses were in the
1st quintile compared to the Fee Universe where the 1st quintile represents the
lowest fees or expenses among the group; (2) 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; (3) the Manager has contractually
agreed to waive fees and/or reimburse expenses to the extent necessary to
maintain a competitive total expense ratio for the Cash Management, Platinum,
and PlanAhead Classes of the Fund; and (4) the Manager's profitability analysis
indicated that it incurred a loss on the services it provided to the Fund.

     Based on these considerations and those noted above with respect to all
Funds, the Board: (1) concluded that the fees paid to the Manager under the
Agreements are fair and reasonable; (2) concluded that the profits to the
Manager are reasonable in light of the quality of services provided to the Fund,
including direct management of the Fund's assets; (3) determined that the Fund
and its shareholders would benefit from the Manager's continued management of
the Fund; and (4) approved the renewal of the Agreements with respect to the
Fund.
