FELLOW SHAREHOLDERS,

Enclosed please find the Annual Report for the American Beacon Select Funds for
the year ended December 31, 2006. During this time, the Select Funds
outperformed their respective peer groups.

     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, the American Beacon
Money Market Select Fund one-year return of 5.08% outperformed the Lipper
Institutional Money Market Average return by 36 basis points (0.36%). The
American Beacon U.S. Government Money Market Select Fund also outperformed the
Lipper Institutional U.S. Government Money Market Average with a one-year return
of 5.04% versus 4.69%.

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 Fed's 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
producers 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 SELECT FUNDS
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 Money Market
Select Fund was 5.08%. The Fund outperformed the Lipper Institutional Money
Market Average return of 4.72% by 36 basis points (0.36%). Lipper Inc. ranked
the Fund 6th among 357, 4th among 291, and 4th among 233 Institutional Money
Market Funds for the one-year, three-year and five-year periods ended December
31, 2006, respectively.

     For the year ended December 31, 2006, the total return of the U.S.
Government Money Market Select Fund was 5.04%. The Fund outperformed the Lipper
Institutional U.S. Government Money Market Average return of 4.69% by 35 basis
points (0.35%). Lipper Inc. ranked the Fund 3rd among 147, 2nd among 126 and 2nd
among 106 Institutional U.S. Government Money Market Funds for the one-year,
three-year and five-year periods ended December 31, 2006, respectively.

     The Lipper Institutional Money Market Average and the Lipper Institutional
U.S. Government Money Market Average are calculated by taking an arithmetic
average of the returns of the mutual funds in the Lipper Institutional Money
Market Funds and the Lipper Institutional U.S. Government Money Market Funds
categories, respectively. 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)    The Fund's performance is derived from a combination of the Fund's
       performance and that of another fund (the "Companion Fund") not included
       in this report. The Companion Fund has been managed by American Beacon
       Advisors since its inception on September 1, 1987. Like the Fund, the
       Companion Fund invests all of its investable assets in a corresponding
       Portfolio of the American Beacon Master Trust. The performance results
       from inception through December 31, 1999 are those of the Companion Fund.
       The Fund began offering its shares on January 1, 2000. Thus, performance
       results shown from that date through December 31, 2006 are for the Fund.
       Because the Companion Fund had higher expenses, its performance was worse
       than the Fund would have realized in the same period. A portion of the
       fees charged to the Money Market Fund was waived through 2001.
       Performance prior to waiving fees was lower than the actual returns for
       periods prior to 2001.

(3)    The Fund's performance is derived from a combination of the Fund's
       performance and that of another fund (the "Companion Fund") not included
       in this report. The Companion Fund has been managed by American Beacon
       Advisors since its inception March 2, 1992. Like the Fund, the Companion
       Fund invests all of its investable assets in a corresponding Portfolio of
       the American Beacon Master Trust. The performance results from inception
       through November 30, 2001 are those of the Companion Fund. The Fund began
       offering its shares on December 1, 2001. Thus, performance results from
       that date through December 31, 2006 are for the Fund. Because the
       Companion Fund had moderately higher expenses, their performance was
       slightly worse than the Fund would have realized in the same period. A
       portion of the fees charged to the U.S. Government Fund has been waived.
       Performance prior to waiving fees was lower than the actual returns
       shown.

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

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.

AMERICAN BEACON SELECT FUNDS
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
American Beacon Select Funds

We have audited the accompanying statements of assets and liabilities of
American Beacon Select Funds, comprised of the American Beacon Money Market
Select Fund and the American Beacon U.S. Government Money Market Select 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 Select 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 SELECT FUNDS
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     American Beacon Select 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 Select Fund and American Beacon U.S. Government
Money Market Select Fund (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: the American Beacon Money Market
Select Fund invests assets in the American Beacon Master Money Market Portfolio
and the American Beacon U.S. Government Money Market Select Fund ("U.S.
Government Fund") invests assets in the American Beacon Master U.S. Government
Money Market Portfolio. Each Fund has the same investment objectives as its
corresponding American Beacon Master Trust Portfolio. The value of such
investments reflects each Fund's proportionate interest in the net assets of the
corresponding portfolio (66.70% and 95.25% at December 31, 2006, of the American
Beacon Master Money Market and U.S. Government Money Market Portfolios,
respectively) (each a "Portfolio" and collectively the "Portfolios"). The
financial statements of the Portfolios are included elsewhere in this report and
should be read in conjunction with the Funds' financial statements.

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

Valuation of Investments

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

Investment Income

     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.

Dividends

     The Funds generally declare dividends daily from net investment income and
net short-term 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.

Expenses

     Expenses directly attributable to a Fund are charged to that Fund's
operations. Expenses incurred by the Trust with respect to both Funds are
allocated in proportion to the net assets of each Fund, except where allocations
of direct expenses to each Fund can otherwise be made fairly. Each share of each
Fund bears equally those expenses that are allocated to the Fund as a whole.

AMERICAN BEACON SELECT FUNDS
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006

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 the
Portfolio), less liabilities, by the number of Fund shares outstanding.

Use of Estimates

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

Recently Issued Accounting Pronouncements

     On July 13, 2006, the Financial Accounting Standards Board ("FASB")
released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes"
("FIN 48"). FIN 48 provides guidance on how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing each Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. 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.  FEES AND TRANSACTIONS WITH AFFILIATES

Reimbursement of Expenses

     The Manager contractually agreed to reimburse the U.S. Government Fund for
other expenses through February 28, 2007 to the extent that total annual Fund
operating expenses exceed 0.12%. For the twelve months ended December 31, 2006,
the Manager reimbursed expenses totaling $23,524 to the U.S. Government Fund.

AMERICAN BEACON SELECT FUNDS
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006

Expense Reimbursement Plan

     The Funds have adopted an Expense Reimbursement Plan whereby the Manager
may seek recoupment of expenses reimbursed for a period of up to three years.
However, recoupment will occur only if a Fund's average net assets have grown or
expenses have declined sufficiently to allow recoupment without causing its
expense ratio to exceed the previously agreed upon contractual expense limit.

     Reimbursed expenses subject to potential recovery for the U.S. Government
Fund totaling $2,418, $25,649 and $23,524, will expire in 2007, 2008 and 2009
respectively. The U.S. Government Fund has not recorded a liability for this
potential reimbursement due to the current assessment that a reimbursement is
unlikely. Fees waived during 2003 totaling $11,073 expired in 2006 and will not
be reimbursed to the Manager.

     During the twelve months ended December 31, 2006, due to asset growth and a
reduction of expenses, the Manager recouped $49,000 from the Money Market Select
Fund for expenses waived during 2003 and 2004 totaling $2,724 and $46,276,
respectively. Fees waived during 2003 totaling $5,278 expired in 2006 and will
not be reimbursed to the Manager.

3.  FEDERAL INCOME TAXES

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

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

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

     The tax character of distributions paid for the year ended December 31,
2006 and the year ended 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 the same as book. The cost basis of investments for federal income
tax purposes was also the same as the book basis.

     The Funds do not have capital loss carryforwards as of December 31, 2006.

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 schedule of investments, of American Beacon Master Trust, comprised of the
American Beacon Money Market Portfolio and the American Beacon U.S. Government
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.

AMERICAN BEACON MASTER TRUST
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

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

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

AMERICAN BEACON MASTER TRUST

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

        accountant:

        - to approve, prior to appointment, the engagement of auditors to
          annually audit and provide their opinion on the Trusts' financial
          statements, and, in connection therewith, reviewing and evaluating
          matters potentially affecting the independence and capabilities of
          the auditors;
        - to approve, prior to appointment, the engagement of the auditors to
          provide non-audit services to the Trusts, an investment adviser to
          any series of the Trusts or any entity controlling, controlled by,
          or under common control with an investment adviser ("adviser

          engagement relates directly to the operations and financial
          reporting of the Trusts;
        - to consider whether the non-audit services provided by a Trust's
          auditor to an investment adviser or any adviser affiliate that
          provides ongoing services to a series of the Trusts, which services
          were not pre-approved by the Committee, are compatible with
          maintaining the auditor's independence;
        - to review the arrangements for and scope of the annual audit and
          any special audits; and
        - to review and approving the fees proposed to be charged to the
          Trusts by the auditors for each audit and non-audit service.
