(BILL QUINN PICTURE)


FELLOW SHAREHOLDERS,

Iam pleased to present to you the annual report for the American Beacon S&P 500,
International Equity, and Small Cap Index Funds for the year ended December 31,
2006.

     The U.S. and international equity markets finished the year on a positive
note due to the continuing strong performance of the economy, lower oil prices,
and the Federal Reserve taking a neutral policy on interest rates. The S&P 500
reported a one-year return of 15.79%. The MSCI EAFE Index reported a one-year
total return of 26.34%.

     The Institutional Class of the S&P 500 Index Fund ended the year with a
one-year return of 15.69% and the Small Cap Index Fund delivered a one-year
return of 17.85%. The International Equity Index Fund ended the year with a
positive return of 26.52%. Looking forward, each Fund will continue to pursue
its objective to continue to replicate the returns, before expenses, of its
corresponding Index.

     Please review the enclosed market overviews, portfolio listings, and

DOMESTIC MARKET OVERVIEW
DECEMBER 31, 2006 (UNAUDITED)
- --------------------------------------------------------------------------------


The broad-market S&P 500(R) Index rose 15.79% for the year. Large-cap value
stocks significantly outperformed shares of large-cap growth companies, with the
Russell 1000(R) Value Index advancing 22.25% versus the 9.07% return of the
Russell 1000(R) Growth Index. In addition, the returns of small-capitalization
stocks exceeded those of large-capitalization company shares, as the Russell
2000(R) Index climbed 18.37%.

     The Federal Reserve Board (the "Fed") raised the target federal funds rate
in four increments of 0.25% during 2006, bringing the target rate from 4.25% to
5.25%. However, the Fed held the rate steady at its meetings on August 8,
September 20, October 25 and December 12, 2006.

     Strong growth in corporate earnings and significant upward revisions to
earnings expectations have been a major driver of the equity bull market since
2003. Although the rate of upgrading has slowed from the exceptionally strong
rates in previous years, recent news from the major corporate sectors generally
has been upbeat. Earnings came in ahead of expectations in the last earnings
rounds in Europe, Japan and the U.S., and have supported the rally in equities
over recent months. Historic global profits growth remains around 20%.

     The U.S. economy downshifted in 2006 with a very significant slowdown in
housing leading the way. Corporate profit growth rose a double-digit percentage
for an unprecedented fourth year in a row. Commodity price volatility increased
significantly with an early-year run-up, followed by a mid-year pullback. Most
of the year featured an inverted yield curve as the Fed took its market rate up
to 5.25%, while the 10-year Treasury note yield spent much of the year between
4.5% and 5%. Once again, non-U.S. markets, with the notable exception of Japan,
outperformed the U.S. as the U.S. Dollar resumed its weakness.

     While overall the year was a good one for equities, the first significant
correction since 2002 enabled a change in leadership from smaller-cap, lower-
quality, more cyclical stocks to larger-cap, higher-quality, more predictable
stocks. After a brief mid-year scare, inflation pressures remained fairly low
around the world, which was good news, especially in light of the unprecedented
run-up in industrial commodity prices. In that regard, oil prices set a new all-
time high in the summer, but corrected noticeably during the fall, giving
further support to the equity market rally in the second half of 2006. The year
also featured unprecedented share buy-backs and mergers-and-acquisition activity
as well as a switch in Congress from Republican to Democratic leadership. The
year 2006 ended with the world awash in liquidity, global growth remained strong
despite the U.S. slowdown, record-high U.S. profitability, inflation and
interest rates fairly low and confidence levels relatively strong.

     For the twelve months ended December 31, 2006, the total return of the
Institutional Class of the American Beacon S&P 500 Index Fund was 15.69%,
slightly below the S&P 500 Index ("Index") return of 15.79% and slightly in
excess of the Lipper S&P 500 Objective Funds Index return of 15.55%.

1.    Performance shown is historical and may not be indicative of future
      returns. Investment returns and principle value will vary, and shares may
      be worth more or less at redemption than at original purchase. Performance
      shown is as of date indicated, and current performance may be lower or

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

2.    Fund performance for the ten-year period represents the total returns
      achieved by the Institutional Class from 12/31/06 up to 3/2/98, the
      inception date of the PlanAhead Class, and the returns of the PlanAhead
      Class since its inception. Because the Institutional Class had lower
      expenses, its performance was better than the PlanAhead Class would have
      realized during the same period. A portion of the fees charged to the
      PlanAhead Class of the Fund was waived through 2002. Performance prior to
      waiving fees was lower than the actual returns shown for periods prior to
      2002.

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

     The strong positive trends for equities in 2006 meant gains across all
sectors for the S&P 500 Index, but there were clear leaders and laggards. The
Telecommunications Services group was the full-year winner with a 36.8% gain.
Solid dividends, stable cash flow, and the prospective consolidation of
BellSouth into AT&T helped the sector recover from several years of sluggish
performance. Energy was the second best performer in 2006, adding 24.3% on the
year. Even though oil prices stabilized in the second half, their average level
through the year was easily high enough to bring gushing profits to energy
firms.

     The weakest sectors in 2006, ironically enough, were two traditional growth
areas: Health Care and Information Technology, returning full-year gains of 7.5%
and 10.2%, respectively. Although there were numerous companies in these sectors
that demonstrated impressive growth in profits and prospects, others confronted
challenging competition, and some ran afoul of compensation scandals. Health
care firms and semiconductor companies were more vulnerable to stock option
incentive schemes which proved at best embarrassing and at worst dishonest.

     The best individual performing security in the Fund for the year 2006 was
Alleghany Technologies which recorded a stellar 153.0% gain. That remarkable
performance only proved to shadow the other two securities that posted triple
digit returns for the year. Terex, added to the benchmark in December, returned
an impressive 117.4% for the year while NVIDIA advanced 102.5%.

     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.

that the characteristics of the portfolio closely track the characteristics of
the Index.

INTERNATIONAL MARKET OVERVIEW
DECEMBER 31, 2006 (UNAUDITED)

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


International equity markets generated positive performance in 2006 as European
economic growth continued to strengthen. During the reporting period,
international equity markets outperformed U.S. equity markets.

     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 rate 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 25 basis points 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.

     International equity markets began the third quarter of 2006 with a decline
during the first two weeks of July. However, the subsequent recovery resulted in
a gain of 1.0% for the MSCI EAFE Index ("EAFE") for the month. There were no
significant variations in regional performances, but the Europe, Emerging Europe
and Latin America markets outperformed those in Japan and Emerging Asia.

     The markets continued to rally in August and September. The main global
sector trend, late in the quarter, was the underperformance of metals and
resources, reflecting the weakness in commodity prices. Financials,
Telecommunication Services, Information Technology and Consumer Staples each
outperformed the broad market. The Information Technology sector outperformed
the EAFE index for the second consecutive month in September, following its
substantial underperformance earlier in the year. Consumer Staples benefited
from the decline in oil prices.

     There is some evidence that slowing corporate earnings momentum in Europe
may be easing. Analysts' earnings revisions stabilized during the fourth quarter
following a period of deceleration in the summer. Although there is little doubt
that the European economy has ended 2006 with less momentum than a year ago,
there are some signs that domestic demand is helping to ease the transition.
Consumer spending in France and retail sales in Spain have exceeded expectations
even as manufacturing confidence appears to be peaking.

     Leading indicators of activity, such as business confidence, remain
relatively buoyant. However, it is important to note that these measures have
tended to overstate activity in the recent past. Looking ahead, we believe the
approach of fiscal tightening in Germany and Italy is likely to drive a moderate
downshift in these indicators during the first quarter of 2007.

     The European Central Bank remains committed to normalizing interest rates.
This year, though, we believe that there eventually will be an extended pause as
core inflation abates and the effects of fiscal changes are assessed, although
rates could reach between 3.5% and 4% before this happens. The Euro appreciated
significantly versus the U.S. Dollar and the Japanese Yen amid expected
increases in Euro interest rates.

     Given the persistence of the gearing to global economic conditions, it is
unlikely that the Japanese market will deliver more revenue surprises than the
rest of the world. However, in the medium term, we believe that Japanese
companies may have greater potential for margin expansion than their Western
counterparts as a result of their greater exposure to commodity costs and
impressive ongoing control of labor expenses.

     Recent economic data, while far from disastrous, has not inspired
confidence that Japan has decoupled from the U.S. and mainland Asian economies.
Gross domestic product growth has remained at an annualized rate of
approximately 1.0% since the spring of 2006, with the only areas of strength
being exports and business investment (which is itself highly correlated with
exports). The third quarter 2006 consumption report and subsequent retail sales
data emphasize that the domestic household demand miracle is yet to materialize
and gearing to the global economy remains a key factor.

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


     All 21 countries of the EAFE Index posted positive returns for the period.
Spain (up 49.4%), Portugal (up 47.4%) and Ireland (up 46.8%) were the leading
regional performers. At the other end of the spectrum were Japan (up 6.2%), New
Zealand (up 16.6%) and Switzerland (up 27.4%).

     With regards to sector performance, all of the 10 sectors in EAFE posted
positive returns. Utilities (up 49.0%), Materials (up 32.0%) and
Telecommunication Services (up 29.5%) were the three top-performing sectors of
the period. Information Technology (up 11.9%), Energy (up 17.1%) and Health Care
(up 18.3%), which were the three lowest performing sectors, still contributed
positive returns for the year.

     At the individual security level, the top performers for the year were
Paladin Resources and OC Oerlikon Corp. with returns of 367.5% and 228.7%,
respectively. The worst performers were Aiful Corp. and BWIN with returns of -
66.9% and -79.0%, respectively.

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

FUND EXPENSES
DECEMBER 31, 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, distribution (12b-1) 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 July 1, 2006 through
December 31, 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 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.

</Table>


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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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


The Board of Trustees and Shareholders of
American Beacon Funds

     We have audited the accompanying statements of assets and liabilities of
American Beacon Funds, comprised of the American Beacon S&P 500 Index Fund, the
American Beacon Small Cap Index Fund, and the American Beacon International
Equity Index Fund (collectively, the "Funds") as of December 31, 2006, and the
related statements of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the five years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Funds' management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

     We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Funds' internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Funds' internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of December 31, 2006, by correspondence with the Master
Portfolios. We believe that our audits provide a reasonable basis for our
opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
American Beacon Funds at December 31, 2006, the results of their operations for
the year then ended, the changes in their net assets for each of the two years
in the period then ended, and the financial highlights for each of the five
years in the period then ended, in conformity with U.S. generally accepted
accounting principles.

     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

     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

     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:




CLASS:                                     OFFERED TO:                                   SERVICE FEES:
- ------                                     -----------                                   -------------

                                                                                                   

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



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

  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.

  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



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

                                       14



AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS -- CONTINUED
DECEMBER 31, 2006
- --------------------------------------------------------------------------------


gains (losses) of each Portfolio are allocated pro rata among the investors in
that Portfolio at the time of such determination.

  Dividends to Shareholders

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

  Allocation of Income, Expenses, Gains and Losses

     Income, expenses (other than those attributable to a specific class), gains
and losses are allocated daily to each class of shares based upon the relative
proportion of net assets represented by such class. Operating expenses directly
attributable to a specific class are charged against the operations of that
class.

  Valuation of Shares

     The price per share is calculated on each day on which shares are offered
for sale. Net asset value per share is computed by dividing the value of each
Fund's total assets (which includes the value of the Fund's 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.

  Recently Issued Accounting Pronouncements

     On July 13, 2006, the Financial Accounting Standards Board ("FASB")
released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes"
("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing each Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. FIN 48 is
effective for fiscal years beginning after December 15, 2006 and is to be
applied to all open tax years as of the effective date. At this time, the
Manager is evaluating the implications of FIN 48 and its potential impact on the
financial statements. The Fund's net asset value per share will reflect FIN 48
adjustments no later than June 29, 2007, and any adjustments will be reflected
in the Fund's semi-annual report to shareholders.

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

  Other

     Under the Trust's organizational documents, its officers and directors are
indemnified against certain liability arising out of the performance of their
duties to the Trust. In the normal course of business, the Trust enters into



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

                                       15



AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS -- CONTINUED

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


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 compensation for performing the duties required under
the Administrative Services Agreement, the Manager receives an annualized fee of
0.05% of the average daily net assets of the Institutional Class of the S&P 500
Index Fund, International Equity Index Fund, and 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. For the year ended December 31, 2006 there are no
fees subject to recoupment.

  Subadministration Agreement

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

  Other

     At December 31, 2006, the employee benefit plans of AMR Corporation and its
subsidiary companies owned 89.2% of the Institutional Class of the S&P 500 Index
Fund, 99.4% of the Small Cap Index Fund and 76.4% of the International Equity
Index Fund.

3.  FEDERAL INCOME TAXES

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

     Dividends are categorized in accordance with federal income tax regulations
which may treat certain transactions differently than U.S. generally accepted
accounting principles. Accordingly, the character of distributions

</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, the realization for tax purposes of
unrealized gains/(losses) on certain derivative instruments, reclassifications
of income from real estate investment securities, and the realization for tax
purposes of unrealized gains /(losses) on investments in passive foreign
investment companies.

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

STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006
- --------------------------------------------------------------------------------



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 December 31,
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 for financial
statement purposes. Dividend income is recorded on the ex-dividend date.
Interest income is recorded daily on the accrual basis and includes amortization
of premium and accretion of discount on investments. Realized gains and losses
from securities transactions are recorded on the basis of identified cost.
Expenses are accrued daily based on average daily net assets.

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

  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



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

                                       36



STATE STREET EQUITY 500 INDEX PORTFOLIO
NOTES TO FINANCIAL STATEMENTS -- CONTINUED
DECEMBER 31, 2006
- --------------------------------------------------------------------------------


Portfolio are deemed to have been "passed through" to the Portfolio's partners
in proportion to their holdings in the Portfolio, regardless of whether such
items have been distributed by the Portfolio. Each partner is responsible for
tax liability based on its distributive share; therefore, no provision has been
made for federal income taxes.

  Futures:

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

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

  Use of Estimates:

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

3. SECURITIES TRANSACTIONS

     For the year ended December 31, 2006, purchases and sales of investment
securities, excluding short-term investments, futures contracts, and in-kind
contributions and withdrawals, aggregated to $237,271,572 and $269,069,491,
respectively. The aggregate value of in-kind contributions and withdrawals were
$8,053,539 and $0, respectively.

     At December 31, 2006, the book cost of investments was $1,762,589,363 which
approximates cost computed on a federal tax basis. The aggregate gross
unrealized appreciation and gross unrealized depreciation was $1,064,901,605 and
$64,775,938, respectively, resulting in net appreciation of $1,000,125,667 for
all securities as computed on a federal income tax basis.

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

4. RELATED PARTY FEES AND TRANSACTIONS

     The Portfolio has entered into an investment advisory agreement with SSgA
Funds Management, Inc. ("SSgA FM" or the "Adviser"), a subsidiary of State
Street Corp. and an affiliate of State Street, under which SSgA FM directs the
investments of the Portfolio in accordance with its investment objective,
policies, and limitations. The Trust has contracted with State Street to provide
custody, administration and transfer agent services to the Portfolio. In
compensation for SSgA FM's services as investment adviser and for State Street's
services as administrator, custodian and transfer agent (and for assuming
ordinary operating expenses of the Portfolio, including ordinary legal, audit
and trustees expense), State Street receives a unitary fee, calculated daily, at
the annual rate of 0.045% of the Portfolio's average daily net assets.

     Certain investments made by the Portfolio were made in securities
affiliated with State Street and SSgA FM. Investments in State Street Corp., the
holding company of State Street, were made according to its representative

portion of the S&P 500(R) Index. The market value of this investment at December
31, 2006 is listed in the Portfolio of Investments.

5. INDEMNIFICATIONS

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

6.  NEW ACCOUNTING PRONOUNCEMENTS

     In July 2006, the Financial Accounting Standards Board issued
Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an
Interpretation of FASB Statement No. 109" (the "Interpretation"). The
Interpretation establishes for all entities, including pass-through entities
such as the Portfolio, a minimum threshold for financial statement recognition
of the benefit of positions taken in filing tax returns (including whether an
entity is taxable in a particular jurisdiction), and requires certain expanded
tax disclosures. The Interpretation is effective for fiscal years beginning
after December 15, 2006, and is to be applied to all open tax years as of the
date of effectiveness. On December 22, 2006, the Securities and Exchange
Commission notified the industry that the implementation of the Interpretation
must be incorporated no later than the last day on which a NAV is calculated
preceding the Portfolio's 2007 semi-annual report, June 29, 2007. Management
continues to evaluate the application of the Interpretation to the Portfolio,
and is not in a position at this time to estimate the significance of its
impact, if any, on the Portfolio's financial statements.

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

STATE STREET EQUITY 500 INDEX PORTFOLIO
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------



To the Board of Trustees of State Street Master Funds and
Owners of Beneficial Interest of State Street Equity 500 Index Portfolio:

     We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of the State Street Equity 500 Index
Portfolio (one of the portfolios constituting State Street Master Funds) (the
Portfolio) as of December 31, 2006, and the related statement of operations for
the year then ended, the statements of changes in net assets for each of the two
years in the period then ended and the financial highlights for each of the five
years in the period then ended. These financial statements and financial
highlights are the responsibility of the Portfolio's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

     We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Portfolio's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Portfolio's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of December 31, 2006, by correspondence with the
custodian and brokers. We believe that our audits provide a reasonable basis for
our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
State Street Equity 500 Index Portfolio of State Street Master Funds at December
31, 2006, the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended and the
financial highlights for each of the five years in the period then ended, in
conformity with U.S. generally accepted accounting principles.

deciding whether to renew the Advisory Agreement, the Trustees considered
various factors, including (i) the nature, extent and quality of the services
provided by the SSgA Funds Management, Inc. (the "Adviser") under the Advisory
Agreement, (ii) the investment performance of the Portfolio, (iii) the costs to
the Adviser of its services and the profits realized by the Adviser and its
affiliates from their relationship with the Trust, (iv) the extent to which
economies of scale would be realized if and as the Trust grows and whether the
fee levels in the Advisory Agreement reflect these economies of scale, and (v)
any additional benefits to the Adviser from its relationship with the Trust.

     In considering the nature, extent and quality of the services provided by
the Adviser, the Trustees relied on their prior direct experience as Trustees of
the Trust as well as on the materials provided at the Meeting. The Board
reviewed the Adviser's responsibilities under the Advisory Agreement and noted
the experience and expertise that would be appropriate to expect of an adviser
to the Portfolio, which is an index fund. The Trustees reviewed the background
and experience of the Adviser's senior management, including those individuals
responsible for the investment and compliance operations relating to the
investments of the Portfolio, and the responsibilities of the latter with
respect to the Portfolio. They also considered the resources, operational
structures and practices of the Adviser in managing the Portfolio's investments,
in monitoring and securing the Portfolio's compliance with its investment
objective and policies with respect to its investments and with applicable laws
and regulations, and in seeking best execution of portfolio transactions. The
Trustees also considered information about the Adviser's overall investment
management business, noting that the Adviser manages assets for a variety of
institutional investors and that the Adviser and its affiliates had over $1.6
trillion in assets under management as of September 30, 2006. They reviewed
information regarding State Street's business continuity and disaster recovery
program. Drawing upon the materials provided and their general knowledge of the
business of the Adviser, the Trustees determined that the experience, resources
and strength of the Adviser in the management of index products is exceptional.
As discussed more fully below, they also determined that the advisory fee for
the Portfolio was fair and reasonable and that its performance and expense ratio
was satisfactory. On the basis of this review, the Trustees determined that the
nature and extent of the services provided by the Adviser to the Portfolio was
appropriate, had been of uniformly high quality, and could be expected to remain
so.

STATE STREET EQUITY 500 INDEX PORTFOLIO
GENERAL INFORMATION (UNAUDITED) -- CONTINUED
DECEMBER 31, 2006
- --------------------------------------------------------------------------------


     The Trustees noted that, in view of the investment objective of the
Portfolio, the investment performance was satisfactory. The Trustees noted that
the performance of the Portfolio in absolute terms was not of the importance
that normally attaches to that of actively-managed funds. Of more importance to
the Trustees was the extent to which the Portfolio achieved its objective of
replicating, before expenses, the total return of the S&P 500 Index. Drawing
upon information provided at the Meeting and upon reports provided to the
Trustees by the Adviser throughout the preceding year, they determined that the
Portfolio had in fact tracked the index within an acceptable range of tracking
error. Accordingly, they concluded that the performance the Portfolio was
satisfactory.

     The Trustees considered the profitability to the Adviser and its affiliate,
State Street, of the advisory relationships with the Trust. The Trustees had
been provided with data regarding the profitability to the Adviser and its
affiliated service providers with respect to the Portfolio individually, and on
an aggregate basis, for the year ended September 30, 2006. Having discussed with
representatives of the Adviser the methodologies used in computing the costs
that formed the bases of the profitability calculations, they concluded that
these methodologies were reasonable and turned to the data provided. After
discussion and analysis they concluded that, to the extent that the Adviser's
and State Street's relationships with the Trust had been profitable to either or
both of those entities, the profitability was in no case such as to render the
advisory fee excessive.

     In order better to evaluate the Portfolio's advisory fee, the Trustees had
requested comparative information from Lipper Inc. with respect to fees paid by,
and expense ratios of, similar funds. The Trustees found that that the
Portfolio's advisory fee and total expense ratio were lower than the average for
its peer group. The Trustees concluded that the data available provided
confirmation of the reasonableness of the Adviser's fee. The Board determined
that the Adviser's fees were fair and reasonable.

     In considering whether the Adviser benefits in other ways from its
relationship with the Trust, the Trustees also considered whether the Adviser's
affiliates may benefit from the Trust' relationship with State Street as fund
administrator, custodian and transfer agent. They noted that the Adviser
utilizes no soft-dollar arrangements in connection with the Portfolio's
brokerage transactions. The Trustees concluded that, to the extent that the
Adviser or its affiliates derive other benefits from their relationships with
the Trust, those benefits are not so significant as to render the Adviser's fees
excessive.

     The Board also considered the extent to which economies of scale may be
realized by the Portfolio as assets grow and whether the Portfolio's fee levels
reflect such economies of scale, if any, for the benefit of investors. In
considering the matter, the Board determined that, to the extent economies of
scale were in fact realized, such economies of scale were shared with the
Portfolio by virtue of advisory fees of comparatively low levels that subsumed
economies of scale in the fees themselves. The Trustees also recognized,
however, that should sustained, substantial asset growth be realized in the
future, it might be necessary to consider additional measures.

MASTER SMALL CAP INDEX SERIES
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006
- --------------------------------------------------------------------------------


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

  (a) Valuation of investments

     Equity securities that are held by the Series that are traded on stock
exchanges or the NASDAQ Global Market are valued at the last sale price or
official close price on the exchange, as of the close of business on the day the
securities are being valued or, lacking any sales, at the last available bid
price for long positions, and at the last available asked price for short
positions. In cases where equity securities are traded on more than one
exchange, the securities are valued on the exchange designated as the primary
market by or under the authority of the Board of Trustees of the Trust. Long
positions traded in the over-the-counter ("OTC") market, NASDAQ Capital Market
or Bulletin Board are valued at the last available bid price or yield equivalent
obtained from one or more dealers or pricing services approved by the Board of
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 or purchased are valued at the last sales price in the case
of exchange-traded options. Options traded in the OTC market are valued at the
last asked price (options written) or the last bid price (options purchased).
Swap agreements are valued based upon quoted fair valuations received daily by
the Series from a pricing service or counterparty. Financial futures contracts
and options thereon, which are traded on exchanges, are valued at their last
sale price as of the close of such exchanges. Obligations with remaining
maturities of 60 days or less are valued at amortized cost unless BlackRock
Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock, Inc., 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 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 are generally determined as of the close of business on
the NYSE. Occasionally, events affecting the values of such securities and such
exchange rates may occur between the times at which they are determined and the
close of business on the NYSE that may not be reflected in the computation of
the Series' net assets. If events (for example, a company announcement, market
volatility or a natural disaster) occur during such periods that are expected to
materially affect the value of such securities, those securities will be valued
at their fair value as determined in good faith by the Board of Trustees of

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

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

     Written and purchased options are non-income producing investments.

  (c) Income taxes

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

  (d) Security transactions and investment income

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

  (e) Securities lending

     The Series may lend securities to financial institutions that provide cash
or securities issued or guaranteed by the U.S. government as collateral, which
will be maintained at all times in an amount equal to at least 100% of the
current market value of the loaned securities. The market value of the loaned
securities is determined at the close of business of the Series and any
additional required collateral is delivered to the Series on the next business
day.

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

  (f) Recent accounting pronouncements

     In July 2006, the Financial Accounting Standards Board ("FASB") issued
Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income
Taxes -- an interpretation of FASB Statement No. 109." FIN 48 prescribes the
minimum recognition threshold a tax position must meet in connection with
accounting for uncertainties in income tax positions taken or expected to be
taken by an entity including mutual funds before being measured and recognized
in the financial statements. Adoption of FIN 48 is required for the last net
asset value calculation in the first required financial statement reporting
period for fiscal years beginning after December 15, 2006. The impact on the
Series' financial statements, if any, is currently being assessed.

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

Merrill Lynch Investment Managers, L.P. ("MLIM"), and its affiliates including
Fund Asset Management, L.P. ("FAM"), with BlackRock, Inc. to create a new
independent company. Merrill Lynch has a 49.8% economic interest and a 45%
voting interest in the combined company and The PNC Financial Services Group,
Inc. ("PNC"), has approximately a 34% economic and voting interest. The new
company operates under the BlackRock name and is governed by a board of
directors with a majority of independent members.

     On September 29, 2006, shareholders of the investors of the Series approved
a new Investment Advisory Agreement for the Trust with the Manager. BlackRock
Advisors, Inc. was recently reorganized into a limited liability company and
renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between
the Trust and the Manager became effective on September 29, 2006. Prior to
September 29, 2006, FAM was the Manager. The general partner of FAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch,
which is the limited partner.

     The Manager is responsible for the management of the Series' investments
and provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Series. For such services, the
Series pays a monthly fee at an annual rate of .01% of the average daily value
of the Series' net assets. The Manager (and previously FAM) has entered into a
contractual arrangement with the Series under which all

        $1,969                    $7,920

</Table>


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

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

     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 the Manager, or its
affiliates. As of December 31, 2006, the Series lent securities with a value of
$51,831 to MLPF&S or its affiliates. Pursuant to that order, the Trust has
retained BIM as the securities lending agent for a fee based on a share of the
returns on investment of cash collateral. Prior to September 29, 2006, BIM was
organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate
of FAM, and MLIM, LLC was the Trust's securities lending agent. BIM 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 the Manager or in registered money market funds advised by the
Manager or its affiliates. For the year ended December 31, 2006, BIM received
$179,594 in securities lending agent fees.

     For the year ended December 31, 2006, the Series reimbursed FAM and the
Manager $7,486 and $2,091, respectively, for certain accounting services.

     In addition, MLPF&S received $217 in commissions on the execution of
portfolio security transactions for the Series for the year ended December 31,
2006.

     Prior to September 29, 2006, certain officers and/or trustees of the Trust
were officers and/or directors of FAM, PSI, MLTC, Merrill Lynch, MLIM, and/or
MLIM, LLC.

     Commencing September 29, 2006, certain officers and/or trustees of the
Trust are officers and/or directors of BlackRock, Inc. or its affiliates.

3.  INVESTMENTS:

     Purchases and sales (including in-kind redemptions) of investments,
excluding short-term securities, for the year ended December 31, 2006 were
$197,782,011 and $175,034,540, respectively.

4.  SHORT-TERM BORROWINGS:

     The Trust, on behalf of the Series, along with certain other funds managed
by the Manager and its affiliates (or FAM and its affiliates), is a party to a
$500,000,000 credit agreement with a group of lenders. 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.
On November 22, 2006 the credit agreement was renewed for one year under
substantially the same terms. The Series pays a commitment fee of .06% per annum
based on the Series' pro rata share of the unused portion of the credit
agreement. Amounts borrowed under the credit agreement bear interest at a rate
equal to, at each Series' election, the federal funds rate plus .35% or a base
rate as defined in the credit agreement. The Series did not borrow under the
credit agreement during the year ended December 31, 2006.

MASTER SMALL CAP INDEX SERIES
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
DECEMBER 31, 2006
- --------------------------------------------------------------------------------



To the Investors and Board of Trustees of Quantitative Master Series Trust:

     We have audited the accompanying statement of assets and liabilities,
including the summary schedule of investments, of Master Small Cap Index Series,
one of the portfolios constituting Quantitative Master Series Trust (the
"Trust") as of December 31, 2006, and the related statement of operations for
the year then ended, the statements of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

     We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Trust is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audits included consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of December 31, 2006, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Master Small Cap Index Series of the Quantitative Master Series Trust as of
December 31, 2006, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended,
and its financial highlights for each of the five years in the period then
ended, in conformity with accounting principles generally accepted in the United
States of America.

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

  (a) Valuation of investments

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

     Options written or purchased are valued at the last sale price in the case
of exchange-traded options. Options traded in the OTC market are valued at the
last asked price (options written) or the last bid price (options purchased).
Swap agreements are valued based upon quoted fair valuations received daily by
the Series from a pricing service or 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 BlackRock
Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock, Inc., 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
on the New York Stock Exchange ("NYSE"). The values of such securities used in
computing the net assets of the Series are determined as of such times. Foreign
currency exchange rates are generally determined as of the close of business on
the NYSE. Occasionally, events affecting the values of such securities and such
exchange rates may occur between the times at which they are determined and the
close of business on the NYSE that may not be reflected in the computation of
the Series' net assets. If events (for example, a company announcement, market
volatility or a natural disaster) occur during such periods that are expected to
materially affect the value of such

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


securities, those securities will be valued at their fair value as determined in
good faith by the Trust's Board of Trustees or by the Manager 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 financial futures contracts.
       Financial futures contracts are contracts for delayed delivery of
       securities at a specific future date and at a specific price or yield.
       Upon entering into a contract, the Series deposits and maintains as
       collateral such initial margin as required by the exchange on which the
       transaction is effected. Pursuant to the contract, the Series agrees to
       receive from or pay to the broker an amount of cash equal to the daily
       fluctuation in value of the contract. Such receipts or payments are known
       as variation margin and are recorded by the Series as unrealized gains or
       losses. When the contract is closed, the Series records a realized gain
       or loss equal to the difference between the value of the contract at the
       time it was opened and the value at the time it was closed.

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

     Written and purchased options are non-income producing investments.

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

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

  (c) Foreign currency transactions

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

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


  (d) Income taxes

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

  (e) Security transactions and investment income

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

  (f) Securities lending

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

  (g) Recent accounting pronouncements

     In July 2006, the Financial Accounting Standards Board ("FASB") issued
Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income
Taxes -- an interpretation of FASB Statement No. 109." FIN 48 prescribes the
minimum recognition threshold a tax position must meet in connection with
accounting for uncertainties in income tax positions taken or expected to be
taken by an entity including mutual funds before being measured and recognized
in the financial statements. Adoption of FIN 48 is required for the last net
asset value calculation in the first required financial statement reporting
period for fiscal years beginning after December 15, 2006. The impact on the
Series' financial statements, if any, is currently being assessed.

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

2.  INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

     On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc.
("Merrill Lynch") combined Merrill Lynch's investment management business,
Merrill Lynch Investment Managers, L.P. ("MLIM"), and its affiliates including
Fund Asset Management, L.P. ("FAM"), with BlackRock, Inc. to create a new
independent company. Merrill Lynch has a 49.8% economic interest and a 45%
voting interest in the combined company and The PNC Financial Services Group,
Inc. ("PNC"), has approximately a 34% economic and voting interest. The new
company operates under the BlackRock name and is governed by a board of
directors with a majority of independent members.

     On September 29, 2006, shareholders of the investors of the Series approved
a new Investment Advisory Agreement for the Trust with the Manager. BlackRock
Advisors, Inc. was recently reorganized into a limited liability company and
renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between
the Trust and the Manager became effective on September 29, 2006. Prior to
September 29, 2006, FAM was the Manager. The general partner of FAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch,
which is the limited partner.

     The Manager is responsible for the management of the Series' investments
and provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Series. For such services, the
Series pays a monthly fee at an annual rate of .01% of the average daily value
of the Series' net assets. The Manager (and previously 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. The reimbursements were as follows:

      $52,657                           $15,595
</Table>


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

     For the year ended December 31, 2006, the Series reimbursed FAM and the
Manager $10,377 and $3,750, respectively, for certain accounting services.

     In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"),
an affiliate of the Manager, received $37,152 in commissions on the execution of
portfolio security transactions for the Series for the year ended December 31,
2006.

     Prior to September 29, 2006, certain officers and/or trustees of the Trust
were officers and/or directors of FAM, MLIM, PSI, and/or Merrill Lynch.

     Commencing September 29, 2006, certain officers and/or trustees of the
Trust are officers and/or directors of BlackRock, Inc. or its affiliates.

3. INVESTMENTS:

     Purchases and sales ( including in-kind redemptions) of investments,
excluding short-term securities, for the year ended December 31, 2006 were
$320,252,993 and $143,844,935, respectively.

4. COMMITMENTS:

     At December 31, 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 $2,177,000.

5. SHORT-TERM BORROWINGS:

     The Trust, on behalf of the Series, along with certain other funds managed
by the Manager and its affiliates (or FAM and its affiliates), is a party to a
$500,000,000 credit agreement with a group of lenders. 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.
On November 22, 2006, the credit agreement was renewed for one year under
substantially the same terms. The Series pays a commitment fee of .06% per annum
based on the Series' pro rata share of the unused portion of the credit
agreement. Amounts borrowed under the credit agreement bear interest at a rate
equal to, at each Series' election, the federal funds rate plus .35% or a base
rate as defined in the credit agreement. The Series did not borrow under the
credit agreement during the year ended December 31, 2006.

MASTER INTERNATIONAL INDEX SERIES
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
DECEMBER 31, 2006
- --------------------------------------------------------------------------------



To the Investors and Board of Trustees of Quantitative Master Series Trust:

     We have audited the accompanying statement of assets and liabilities,
including the summary schedule of investments, of Master International Index
Series, one of the portfolios constituting Quantitative Master Series Trust (the
"Trust") as of December 31, 2006, and the related statement of operations for
the year then ended, the statements of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

     We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Trust is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audits included consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of December 31, 2006, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Master International Index Series of the Quantitative Master Series Trust as of
December 31, 2006, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended,
and its financial highlights for each of the five years in the period then
ended, in conformity with accounting principles generally accepted in the United
States of America.

FELLOW SHAREHOLDERS,

I am pleased to present to you the American Beacon Treasury Inflation Protected
Securities Fund Annual Report for the twelve months ended December 31, 2006.

     After 17 consecutive 25-basis point (0.25%) rate hikes, the Federal Open
Market Committee ("FOMC") held interest rates steady at 5.25% at their August
8th meeting. The Federal Reserve Board (the "Fed") will continue to weigh the
risks of accelerating inflation and decelerating economic growth. At the final
FOMC meeting in December 2006, the Fed acknowledged the cooling housing market,
but remained primarily concerned about inflation. The FOMC should hold rates
steady at least through the first half of 2007. The market is focused on slowing
housing and auto data and pricing in an ease for the next move by the Fed
(albeit in the late part of 2007). Fed officials continue to discuss that
additional firming may be needed because inflation remains on the higher-end of
their comfort range.

     The American Beacon Treasury Inflation Protected Securities Fund realized
modest, but positive returns with a 1.05% return for the twelve-month period,
outperforming the Lipper TIPS Index return of -0.09%. Looking forward, the
Treasury Inflation Protected Securities Fund will continue to seek inflation
protection and income by investing primarily in inflation-indexed debt
securities.

detailed financial data. As always, we welcome the opportunity to serve your
financial needs. Should you have any questions about the enclosed information,

                                        /s/ William F. Quinn

MARKET OVERVIEW
DECEMBER 31, 2006 (UNAUDITED)

Following four consecutive federal funds rate increases to begin 2006 and 4.75%
of overall rate hikes, the FOMC paused in the 2-year monetary policy tightening
cycle on August 7th. At its final meeting of the year, on December 12th, the
Federal Reserve held the funds rate steady at 5.25% as they continue to weigh
the impact of "elevated" inflation pressures against a slowing U.S. economy. As
the year closed, the yield curve was priced to reflect 25 basis points (0.25%)
of easing in 2007.

     Key inflation metrics sent conflicting signals to the FOMC in 2006.
Following declines in energy prices, headline CPI receded from the elevated
levels of the first half of the year (3.4% - 4.3% range), with CPI now up 2.5%
over the past year. But core rates of inflation, which exclude more volatile
food and energy prices and have a major impact on monetary policy decisions,
have been steadily rising over the past few years in the context of steadily
rising utilization rates for labor and industry. In December of 2006, core rates
of inflation are close to 2.6% and reached an almost 10-year high of 2.9% in
September, stubbornly above the Fed's professed target range of 1% - 2%.

     Although intermediate and long maturity Treasury inflation protected
securities ("TIPS") yields markedly increased in 2006, TIPS managed to post
positive total returns for the year, as the Lehman U.S. TIPS Index returned
0.41%. Intermediate TIPS, as measured by the Lehman 1-10 Year U.S. TIPS Index,
delivered a total return of 1.56%. With the exception of the two-year TIPS yield
which decreased by 15 basis points (0.15%), TIPS yields generally increased in
parallel by 35-40 (0.35% - 0.40%) basis points across intermediate and
longer-maturities. Yields on 5-, 10- and 30-year TIPS finished the year at
2.47%, 2.41% and 2.28%, respectively. The main driving force behind the rise in
global real yields, particularly in the first half of the year, was an
unprecedented period of global monetary policy tightening inclusive of both G8
and developing nations. For the first time in two decades, the three most
important central banks in the world - the Federal Reserve Bank, the European
Central Bank, and the Bank of Japan - all tightened policy simultaneously.

     Inflation expectations as evidenced as breakeven inflation rates (the
spread between similar maturity nominal and inflation-protected securities),
mirrored movements in headline inflation reaching a high of 2.74% in May and a
low of 2.26% in late December. The second half plunge in inflation expectations
caused TIPS to underperform their nominal counterparts by 1.87% for the full
year. Much of the decline in inflation expectations was driven by sharp
reductions in oil/gasoline prices, exacerbated by unseasonably mild weather in
the Northeast.

     Lastly and importantly, the TIPS market continued to be an integral part of
the fixed income landscape as approximately $72 billion in new supply was
introduced into the market through eight Treasury auctions. The total
outstanding market value of TIPS at the end of 2006 was approximately $370
billion. Additionally, Germany issued its first inflation-linked offering in the
first quarter joining the U.S., Canada, U.K., Sweden, France, Italy, Greece and
Japan as a participant in the nearly $1 trillion global inflation-linked market.

(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 year by 0.51%. While much of the
underperformance can be attributed to Fund expenses, sub-advisor performance
also negatively impacted the Fund over the past twelve months. Much of the
underperformance occurred in the second and third quarters of the year. The
Fund's "bulleted" yield curve strategy hurt performance during the year as
expectations of a steepening real yield curve did not materialize. Lastly, an
allocation to nominal bonds negatively impacted the Fund in the first half of
the year as TIPS outperformed nominal bonds due to strong oil and gas prices and
higher breakeven rates.

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

FUND EXPENSE EXAMPLE

     As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs and (2) ongoing costs, including management fees, administrative service
fees, and other Fund expenses. The examples below are intended to help you
understand the ongoing cost (in dollars) of investing in the Fund and to compare
these costs with the ongoing costs of investing in other mutual funds.

     The examples are based on an investment of $1,000 invested at the beginning
of the period and held for the entire period from July 1, 2006 through December
31, 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 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.

   (5% return before expenses)


*    Expenses are equal to the Fund's annualized expense ratios for the
     six-month period of 0.56% for the Institutional class, multiplied by the
     average account value over the period, multiplied by the number derived by
     dividing the number of days in the most recent fiscal half-year (184) by
     days in the year (365) to reflect the half year period.

reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of December 31, 2006, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audit provides a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
American Beacon Treasury Inflation Protected Securities Fund at December 31,
2006, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and the financial
highlights for each of the periods indicated therein, in conformity with U.S.
generally accepted accounting principles.

AMERICAN BEACON TREASURY INFLATION PROTECTED SECURITIES FUND
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     American Beacon Funds (the "Trust") is organized as a Massachusetts
business trust and is registered under the Investment Company Act of 1940 (the
"Act"), as amended, as a no load, diversified, open-end management investment
company. These financial statements and notes to the financial statements relate
to the American Beacon Treasury Inflation Protected Securities Fund (the
"Fund"), a series of the Trust.

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

Security Valuation

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

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

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

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

Security Transactions and Investment Income

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

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

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

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

Dividends to Shareholders

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

Forward Foreign Currency Exchange Contracts

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

Use of Estimates

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

Recently Issued Accounting Pronouncements

     On July 13, 2006, the Financial Accounting Standards Board ("FASB")
released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes"
("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing the Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. FIN 48 is
effective for fiscal years beginning after December 15, 2006 and is to be
applied to all open tax years as of the effective date. At this time, the
Manager is evaluating the implications of FIN 48 and its potential impact on the
financial statements. The Fund's net asset value per share will reflect FIN 48
adjustments no later than June 29, 2007, and any adjustments will be reflected
in the Fund's semi-annual report to shareholders.

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

Other

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

2. TRANSACTIONS WITH AFFILIATES

Management Agreement

     The Trust and the Manager are parties to a Management Agreement that
obligates the Manager to provide or oversee the provision of all administrative,
investment advisory, and fund management. Investment assets of the Fund are
managed by multiple investment advisors which have entered into separate
investment advisory agreements with the Manager. As compensation for performing
the duties required under the Management Agreement, the Manager receives from
the Fund an annualized fee equal to 0.10% of the average daily net assets plus
amounts paid by the Manager to the investment advisors hired by the Manager to
direct investment activities of the Fund. Management fees paid during the year
ended December 31, 2006 were as follows:



                               AMOUNTS PAID   NET AMOUNTS
MANAGEMENT FEE   MANAGEMENT   TO INVESTMENT   RETAINED BY
     RATE            FEE         ADVISORS       MANAGER
- --------------   ----------   -------------   -----------
                                     
    0.22%          $69,164       $37,742        $31,422


Administrative Services Agreement

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

Investment in Affiliated Funds

     The Fund is permitted, pursuant to an exemptive order by the Securities and
Exchange Commission ("SEC") and procedures approved by the Board, to invest up
to 25% of its total assets in the American Beacon Money Market Select Fund (the
"Select Fund"). The Fund and the Select Fund have the same investment advisor
and therefore, are considered to be affiliated. The Manager serves as investment
advisor to the Select Fund and receives from the Select Fund an annualized fee
equal to 0.10% of the Select Fund's average daily net assets. During the year
ended December 31, 2006, fees earned by the Manager from the Select Fund were
$910.

Interfund Lending Program

     Pursuant to an exemptive order by the SEC, the Fund, along with other
registered investment companies having management contracts with the Manager,
may participate in an interfund lending program as a borrower. This program
provides an alternative credit facility allowing the Fund to borrow from other
participating Funds. For the year ended December 31, 2006, the Fund did not
utilized the credit facility.

3. FEDERAL INCOME TAXES

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

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

     The tax character of distributions paid during the years ended December 31,
2006 and December 31, 2005 were as follows (in thousands):

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

     As of December 31, 2006, the components of distributable earnings on a tax
basis were as follows (in thousands):

Unrealized appreciation ..............................................        12
Unrealized depreciation ..............................................      (521)
                                                                         -------
Net unrealized appreciation/(depreciation) ...........................      (509)
Undistributed ordinary income ........................................        --
Undistributed long-term gain/(loss) ..................................    (1,118)
                                                                         -------
Distributable earnings ...............................................   $ 1,627
                                                                         =======


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

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

     Accordingly, the following amounts represent current year permanent
differences derived from foreign currency transactions and return of capital
that have been reclassified as of December 31, 2006 (in thousands):


                                                                         
Paid-in-capital ......................................................      $(94)
Undistributed net investment income ..................................        96
Accumulated net realized gain (loss) .................................        (1)
Unrealized appreciation (depreciation) of investments, futures
   contracts and foreign currency ....................................        (1)

FELLOW SHAREHOLDERS,

Enclosed please find the Annual Report for the American Beacon Money Market
Funds for the year ended December 31, 2006.

      After 17 consecutive 25-basis point (0.25%) rate hikes, the Federal Open
Market Committee ("FOMC") held interest rates steady at 5.25% at their August
8th meeting. The Federal Reserve Board (the "Fed") will continue to weigh the
risks of accelerating inflation and decelerating economic growth. At the final
FOMC meeting in December 2006, the Fed acknowledged the cooling housing market,
but remained primarily concerned about inflation. The FOMC should hold rates
steady at least through the first half of 2007. The market is focused on slowing
housing and auto data and pricing in an ease for the next move by the Fed
(albeit in the late part of 2007). Fed officials continue to discuss that
additional firming may be needed because inflation remains on the higher-end of
their comfort range.

      Despite rising interest rates earlier in the year, both the Institutional
and the Cash Management Classes of the American Beacon Money Market Fund
one-year returns of 4.99% and 5.05% outperformed the Lipper Institutional Money
Market Average return by 27 (0.27%) and 33 (0.33%) basis points, respectively.
The American Beacon U.S. Government Money Market Fund -- Cash Management Class
also outperformed the Lipper Institutional U.S. Government Money Market Average
with a one-year return of 4.97% versus 4.69%. Both Funds surpassed their
respective Lipper peer groups over all time periods. Additionally, the Municipal
Money Market Fund -- PlanAhead Class posted a return of 2.50%, underperforming
the Lipper Tax-Exempt Money Market Average return of 2.76%.

      Please review the enclosed portfolio listings and detailed financial data.

                                       /s/  WILLIAM F. QUINN

ECONOMIC OVERVIEW
DECEMBER 31, 2006 (UNAUDITED)

The initial estimate of the U.S. gross domestic product ("GDP") growth rate rose
3.5% in the fourth quarter, after rising a modest 2.0% in the third quarter of
2006. Consumer spending was the primary driver, up 4.4%. Consumers used credit
cards to make up for diminished mortgage borrowing power. Business fixed
investment fell 0.4%, the first decline since the first quarter of 2003.
Inventories were up only $35.3 billion, trimming 0.7% from GDP growth. Growth
rose solidly above the Federal Reserve Board's (the "Fed") target after two
quarters of coming in below, leaving room for debate on the implications of
growth. In addition to the up tick in growth, the labor market remains healthy
as payroll gains averaged 136,000 per month during the fourth quarter and the
unemployment rate remained low at 4.5% in December.

      The Federal Open Market Committee ("FOMC") ended a streak of seventeen
consecutive 25 basis point (0.25%) rate hikes at their August 8th meeting,
leaving rates unchanged at 5.25% through the rest of 2006. Fed officials
continue to weigh the risks of a slowing economy against the risks of higher
inflation in determining the future direction of interest rates. At the December
meeting, the Fed acknowledged the cooling housing market and its impact on
economic growth, but inflation remained their chief concern. "...participants
expressed concern that a failure of inflation to moderate as expected could
entail significant costs if an upward drift in inflation expectations ensued,"
the minutes said. As a result, the Fed retained a tightening bias in its
December statement maintaining the phrase that "the extent and timing of any
additional firming that may be needed to address these risks will depend on the
evolution of the outlook for both inflation and economic growth."

      The latest readings of consumer and producer prices indicate that the
easing of inflationary pressures may be slow. The core consumer price index
("CPI") rose 0.2% in December after remaining flat in November, and the core
producer price index ("PPI"), which also rose 0.2% during the month, came in
above economists' expectations. In addition, despite a decline to an annual rate
of 2.2% in November which was unchanged in December, the core personal
consumption expenditures ("PCE") price index remains above the Fed's comfort
range of 1-2%.

      U.S. Treasury yields rose during the fourth quarter as the likelihood of a
Fed ease during the first quarter of 2007 began to dissipate. Though the yield
curve remained inverted, Treasury yields reached five month highs in January
2007 on signals that the housing market is bottoming, inflation remains
stubborn, and employment is strengthening.

      The FOMC should remain on hold at least through the first part of 2007 as
Fed officials wait for signs that inflation is indeed moderating. If inflation
remains above the Fed's comfort level for an extended period of time, an
additional Fed tightening is possible. Despite the Fed's stated tightening bias,
the market continues to expect an ease during the second half of 2007.

PERFORMANCE OVERVIEW
AMERICAN BEACON MONEY MARKET FUND(SM)
DECEMBER 31, 2006 (UNAUDITED)


      As the economy continued to show signs of strength during the year, the
Fed continued tightening monetary policy through June 2006. Since then the Fed
has been on hold with a tightening bias, resulting in a 5.25% fed funds target
by year end. This was a move of 25 basis points (0.25%) for each of the first
four FOMC meetings after starting the year at 4.25%. In response, the American
Beacon Money Market Fund's weighted-average maturity ("WAM") was maintained
below 45 days throughout the year. The primary strategy of the Fund was to buy
variable rate securities, short-dated commercial paper and overnight
investments. Due to maintaining a short WAM in a rising to stable interest rate
environment the Fund outperformed its Lipper peer group. This strategy will stay
in place until economic data suggest the Fed is about to enter into an easing
cycle.

      For the year ended December 31, 2006, the total return of the Cash
Management Class of the American Beacon Money Market Fund was 5.05%. The Fund
outperformed the Lipper Institutional Money Market Average return of 4.72% by 33
basis points (0.33%). Lipper Inc. ranked the Cash Management Class of the Fund
14th among 357, 15th among 291 and 16th among 233 Institutional Money Market
Funds for the one-year, three-year and five-year periods ended December 31,
2006, respectively. The Lipper Institutional Money Market Average is calculated
by taking an arithmetic average of the returns of the mutual funds in the Lipper
Institutional Money Market Funds category. Lipper is an independent mutual fund
research and ranking service that ranks mutual funds in various categories by
making comparative calculations using total returns.

1    Performance shown is historical and may not be indicative of future
     returns. Investment returns will vary, and 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.

2    Fund performance for the five and ten-year periods represent the total
     returns achieved by the Institutional Class from 1/1/97 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 1/1/97. A portion of the fees charged to the Cash
     Management and Platinum classes of the Fund has been waived. Performance
     prior to waiving fees was lower than the actual returns shown.

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

PERFORMANCE OVERVIEW
AMERICAN BEACON MONEY MARKET FUND(SM)

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 July 1, 2006 through December 31,
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 "Actual" line under the heading "Expenses Paid During Period" to estimate
the expenses you paid on your account during this period.


HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     The "Hypothetical" 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.

     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)
DECEMBER 31, 2006 (UNAUDITED)

     As the economy continued to show signs of strength during the year, the Fed
continued tightening monetary policy through June 2006. Since then the Fed has
been on hold with a tightening bias, resulting in a 5.25% fed funds target by
year end. This was a move of 25 basis points (0.25%) for each of the first four
FOMC meetings after starting the year at 4.25%. In response, the American Beacon
U.S. Government Money Market Fund's weighted-average maturity was maintained
below 20 days throughout the year. The primary strategy of the Fund was to buy
short-dated and variable rate agencies along with overnight repurchase
agreements. Due to maintaining short duration in a rising to stable interest
rate environment, the Fund outperformed its Lipper peer group. This strategy
will stay in place until economic data suggest the Fed is about to enter into an
easing cycle.

     For the year ended December 31, 2006, the total return of the Cash
Management Class of the American Beacon U.S. Government Money Market Fund was
4.97%. The Fund outperformed the Lipper Institutional U.S. Government Money
Market Average return of 4.69% by 28 basis points (0.28%). Lipper Inc. ranked
the Cash Management Class of the Fund 7th among 147, 9th among 106 and 8th among
64 Institutional U.S. Government Money Market Funds for the one-year, five-year
and ten-year periods ended December 31, 2006, respectively. The Lipper
Institutional U.S. Government Money Market Average is calculated by taking an
arithmetic average of the returns of the mutual funds in the Lipper
Institutional U.S. Government Money Market Funds category. Lipper is an
independent mutual fund research and ranking service that ranks mutual funds in
various categories by making comparative calculations using total returns.

     Management Class of the Fund has been waived since 2002. Performance prior
     to waiving fees was lower than actual returns shown for periods after 2002.

PERFORMANCE OVERVIEW
AMERICAN BEACON MUNICIPAL MONEY MARKET FUND(SM)
DECEMBER 31, 2006 (UNAUDITED)

     The American Beacon Municipal Money Market Fund maintained a relatively
short average maturity during 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 increased 100
basis points (1.00%) during the year. The investment manager 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 year ended December 31, 2006, the total return of the PlanAhead
Class of the American Beacon Municipal Money Market Fund was 2.50%. The Fund
under-performed the Lipper Tax-Exempt Money Market Average return of 2.76%. 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

PERFORMANCE OVERVIEW
AMERICAN BEACON MUNICIPAL MONEY MARKET FUND(SM)
DECEMBER 31, 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 July 1, 2006 through December 31,
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 "Actual" line under the heading "Expenses Paid During Period" to estimate
the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     The "Hypothetical" 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.

     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 ratios for the
     six-month period of 0.99% and 0.99% for the PlanAhead and Platinum Classes
     respectively, multiplied by the average account value over the period,
     multiplied by the number derived by dividing the number of days in the most
     recent fiscal half-year (184) by days in the year (365) to reflect the
     half-year period.

AMERICAN BEACON FUNDS
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


The Board of Trustees and Shareholders of
American Beacon Funds

We have audited the accompanying statements of assets and liabilities of
American Beacon Funds, comprised of the American Beacon Money Market Fund, the
American Beacon U.S. Government Money Market Fund, and the American Beacon
Municipal Money Market Fund (collectively, the "Funds") as of December 31, 2006,
and the related statements of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the five years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Funds' management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Funds' internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
American Beacon Funds at December 31, 2006, the results of their operations for
the year then ended, the changes in their net assets for each of the two years
in the period then ended, and the financial highlights for each of the five
years in the period then ended, in conformity with U.S. generally accepted
accounting principles.

AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006


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:




AMERICAN BEACON:                  --> invests assets in --> AMERICAN BEACON MASTER TRUST:
- ---------------------------------                           --------------------------------------
                                                      
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 (9.51%,
1.72% and 15.69% at December 31, 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:

<Table>

CASH MANAGEMENT CLASS     Investors making an initial investment of $10 million for       Administrative Service Fee -- 0.07%

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 institutions     Administrative Service Fee -- 0.65%

</Table>

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

AMERICAN BEACON FUNDS
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006


INVESTMENT INCOME AND DIVIDENDS TO SHAREHOLDERS

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

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

ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES

     Income, expenses (other than those attributable to a specific class), gains
and losses are allocated daily to each class of shares based upon the relative
proportion of net assets represented by such class. Operating expenses directly
attributable to a specific class are charged against the operations of that
class.

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. 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.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     On July 13, 2006, the Financial Accounting Standards Board ("FASB")
released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes"
("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing each Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. FIN 48 is
effective for fiscal years beginning after December 15, 2006 and is to be
applied to all open tax years as of the effective date. At this time, the
Manager is evaluating the implications of FIN 48 and its potential impact on the
financial statements. The Fund's net asset value per share will reflect FIN 48
adjustments no later than June 29, 2007, and any adjustments will be reflected
in the Fund's semi-annual report to shareholders.

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

OTHER

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

2. TRANSACTIONS WITH AFFILIATES

ADMINISTRATIVE SERVICES AGREEMENT

     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
services, the Manager receives an annualized fee of 0.07% of the average daily
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.

     The Manager contractually agreed to reimburse the Institutional Class of
the Money Market Fund for other expenses through February 28, 2007 to the extent
total annual fund operating expenses exceed 0.20%. Beginning June 26, 2006 the
Manager voluntarily agreed to reimburse this class for other expenses to the
extent annualized operating expenses exceed 0.18%. The Manager reimbursed
expenses totaling $31,296 to the Institutional Class of the Money Market Fund
during the twelve months ended December 31, 2006.

     The Manager voluntarily reimbursed the PlanAhead Class of the Money Market
Fund for other expenses totaling $3,719 during the twelve months ended December
31, 2006.

EXPENSE REIMBURSEMENT PLAN

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

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

3. FEDERAL INCOME TAXES

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

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

     Dividends are categorized in accordance with federal income tax regulations
which may treat certain transactions differently than U. S. generally accepted
accounting principles. Accordingly, the character of

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

     certain private activity bonds for purposes of the federal alternative
     minimum tax calculation.(unaudited)

     As of December 31, 2006, the components of distributable earnings on a tax
basis were the same as book. The cost basis of investments for federal income
tax purposes was also the same as the book basis.

AMERICAN BEACON MASTER TRUST
Report of Independent Registered Public Accounting Firm


The Board of Trustees and Shareholders of
American Beacon Master Trust


We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of American Beacon Master Trust, comprised of the
American Beacon Money Market Portfolio, the American Beacon U.S. Government
Money Market Portfolio, and the American Beacon Municipal Money Market
Portfolio, (collectively, the "Portfolios") as of December 31, 2006, and the
related statements of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the five years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Portfolios' management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Portfolios' internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Portfolios' internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of December 31, 2006, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
American Beacon Master Trust at December 31, 2006, the results of their
operations for the year then ended, the changes in their net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period then ended, in conformity with U.S. generally
accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     American Beacon Master Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended, as a no load, open-end management
investment company that was organized as a trust under the laws of the
Commonwealth of Massachusetts pursuant to a Declaration of Trust dated as of
November 1, 2004. Prior to November 1, 2004, the Trust was organized as a trust
under the laws of the State of New York. Beneficial interests in the Trust are
divided into separate series, each having distinct investment objectives and
policies. These financial statements relate to the American Beacon Master Money
Market Portfolio, 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") 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 TAXES

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

REPURCHASE AGREEMENTS

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

USE OF ESTIMATES

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

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     On July 13, 2006, the Financial Accounting Standards Board ("FASB")
released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes"
("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing each Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. FIN 48 is
effective for fiscal years beginning after December 15, 2006 and is to be
applied to all open tax years as of the effective date. At this time, the
Manager is evaluating the implications of FIN 48 and its potential impact on the
financial statements. The Fund's net asset value per share will reflect FIN 48
adjustments no later than June 29, 2007, and any adjustments will be reflected
in the Fund's semi-annual report to shareholders.

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

OTHER

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

2.   TRANSACTIONS WITH AFFILIATES

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 twelve months ended December 31, 2006, the Money Market
Portfolio earned $2,108 under the credit facility. This amount is included in
interest income on the financial statements.
