                               HEWITT SERIES TRUST
                          NOTES TO FINANCIAL STATEMENTS
1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Hewitt Money Market Fund (the "Money Market Fund") and Hewitt Institutional
Money Market Fund, (the "Institutional Money Market Fund"), (each a "Fund",
collectively, the "Funds") are diversified series of Hewitt Series Trust (the
"Trust"), an open-end management investment company registered under the
Investment Company Act of 1940, as amended. The Trust was established as a
Delaware business trust organized pursuant to a Declaration of Trust on July 7,
1998.

     Under the Funds' organizational documents, the officers and trustees are
indemnified against certain liabilities that may arise out of their duties to
the Funds. Additionally, in the normal course of business, the Funds enter into
contracts with service providers that contain general indemnification clauses.
The Funds' maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Funds that have not yet
occurred. However, based on experience, the Funds expect the risk of loss to be
remote.

     The following significant accounting policies are consistently followed by
the Trust in the preparation of its financial statements, and such policies are
in conformity with accounting principles generally accepted in the United States
of America ("U.S. GAAP") for investment companies. The preparation of financial
statements in conformity with U.S. GAAP requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

INVESTMENT POLICY AND SECURITY VALUATION

     Each Fund invests substantially all of its assets in the Money Market
Master Portfolio (the "Master Portfolio"), a series of Master Investment
Portfolio ("MIP"). The Master Portfolio has the same investment objective as the
Funds. The value of each Fund's investment in the Master Portfolio reflects each
Fund's interest in the net assets of the Master Portfolio (1.91% and 1.83% for
the Money Market Fund and the Institutional Money Market Fund, respectively as
of December 31, 2003).

     The method by which the Master Portfolio values its securities is discussed
in Note 1 of the Master Portfolio's Notes to Financial Statements, which are
included elsewhere in this report.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

     Each Fund records daily its proportionate interest in the net investment
income and realized and unrealized gains and losses of the Master Portfolio.

     The performance of each Fund is directly affected by the performance of the
Master Portfolio. The financial statements of the Master Portfolio, including
the Schedule of Investments, are included elsewhere in this report and should be
read in conjunction with the corresponding Fund's financial statements.

FEDERAL INCOME TAXES

     The Funds have elected and intends to qualify each year as a "regulated
investment company" under Subchapter M of the Internal Revenue Code. If so
qualified, the Funds will not be subject to federal income tax to the extent
they distribute their net income to shareholders.

                                        6



                               HEWITT SERIES TRUST
                    NOTES TO FINANCIAL STATEMENTS--CONTINUED

     Each Fund is treated as a separate entity for federal income tax purposes.
It is the policy of the Trust that each Fund continue to qualify as a regulated
investment company by complying with the provisions of the Internal Revenue Code
of 1986, as amended (the "Code") applicable to regulated investment companies,
and to distribute substantially all of its investment company taxable income and
any net realized gains (after taking into account any capital loss
carryforwards) sufficient to relieve it from all, or substantially all, federal
income and excise taxes. Accordingly, no provision for federal taxes was
required at December 31, 2003.

     As of December 31, 2003, the components of Distributable Earnings on a tax
basis were as follows: Undistributed Ordinary Income of $2,964 and $31,726 for
the Money Market Fund and the Institutional Money Market Fund, respectively.

     The tax character of distributions paid during 2003 and 2002 for the Funds
were as follows: ordinary income of $269,301 and $694,066 for the Money Market
Fund, respectively, and ordinary income of $814,988 and $1,610,041 for the
Institutional Money Market Fund, respectively.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

     Dividends to shareholders from net investment income of each Fund are
declared daily and distributed monthly. Distributions to shareholders from
capital gains, if any, are declared and distributed annually, generally in
December.

REPORT OF INDEPENDENT AUDITORS

To the Shareholders and Board of Trustees of
Hewitt Series Trust:

     In our opinion, the accompanying statements of assets and liabilities, and
the related statements of operations and of changes in net assets and the
financial highlights present fairly, in all material respects, the financial
position of the Hewitt Money Market Fund and Hewitt Institutional Money Market
Fund, the funds comprising Hewitt Series Trust (collectively the "Funds"), at
December 31, 2003, the results of each of their operations for the year then
ended, the changes in each of their net assets and each of their financial
highlights for the two years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Funds' management; our
responsibility is to express an opinion of these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with auditing standards generally accepted in the United States of America,
which require that we plan and perform the audits to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit 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, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     The financial highlights of the Funds for each of the periods ended from
February 28, 1999 through December 31, 2001 were audited by other auditors,
whose report dated February 11, 2002 expressed an unqualified opinion on those
highlights.

                          MONEY MARKET MASTER PORTFOLIO
                        NOTES TO THE FINANCIAL STATEMENTS
1. SIGNIFICANT ACCOUNTING POLICIES

     Master Investment Portfolio ("MIP") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company organized as a Delaware statutory trust. As of December 31,
2003, MIP offered the following separate portfolios: Asset Allocation, Bond
Index, Extended Index, International Index, LifePath Retirement (formerly
LifePath Income), LifePath 2010, LifePath 2020, LifePath 2030, LifePath 2040,
Money Market, Prime Money Market, Russell 2000 Index, S&P 500 Index and U.S.
Equity Index Master Portfolios.

     These financial statements relate only to the Money Market Master Portfolio
(the "Master Portfolio").

     Under the Master Portfolio's organizational documents, the officers and
trustees are indemnified against certain liabilities that may arise out of their
duties to the Master Portfolio. Additionally, in the normal course of business,
the Master Portfolio enters into contracts with service providers that contain
general indemnification clauses. The Master Portfolio's maximum exposure under
these arrangements is unknown as this would involve future claims that may be
made against the Master Portfolio that have not yet occurred. However, based on
experience, the Master Portfolio expects the risk of loss to be remote.

     The following is a summary of significant accounting policies which are
consistently followed by MIP in the preparation of its financial statements.
Such policies are in conformity with accounting principles generally accepted in
the United States of America ("U.S. GAAP") for investment companies. The
preparation of financial statements in conformity with U.S. GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.

SECURITY VALUATION

     The Master Portfolio uses the amortized cost method of valuation to
determine the value of its portfolio securities in accordance with Rule 2a-7
under the 1940 Act. The amortized cost method, which involves valuing a security
at its cost and accreting or amortizing any discount or premium, respectively,
over the period until maturity, approximates market value.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

     Security transactions are accounted for on trade date. Interest income is
accrued daily. Realized gains and losses on investment transactions are
determined using the specific identification method. The Master Portfolio
amortizes premium and accretes discount using a constant yield to maturity
method.

FEDERAL INCOME TAXES

     In general, MIP believes that the Master Portfolio has and will continue to
be operated in a manner so as to qualify it as a non-publicly traded partnership
for federal income tax purposes. Provided that the Master Portfolio so
qualifies, it will not be subject to any federal income tax on its income and
gain (if any). However, each interestholder in such a Master Portfolio will be
taxed on its distributive share of the Master Portfolio's taxable income in
determining its federal income tax liability. As a non-publicly traded
partnership for federal income tax

                                       18



                         MONEY MARKET MASTER PORTFOLIO
                  NOTES TO THE FINANCIAL STATEMENTS--CONTINUED
purposes, the Master Portfolio will be deemed to have "passed through" to its
interestholders any interest, dividends, gains or losses of the Master Portfolio
for such purposes. The determination of its distributive share will be made in
accordance with the Internal Revenue Code of 1986, as amended (the "Code"), and
regulations promulgated thereunder.

     It is intended that the Master Portfolio's assets, income and distributions
will be managed in such a way that an entity electing and qualifying as a
"regulated investment company" under the Code can continue to qualify by
investing substantially all of its assets through the Master Portfolio, provided
that the regulated investment company meets other requirements for such
qualifications not within the control of the Master Portfolio (e.g.,
distributing at least 90% of the regulated investment company's "investment
company taxable income" annually).

REPURCHASE AGREEMENTS

     Each Master Portfolio may enter into repurchase agreements with banks and
securities dealers. These transactions involve the purchase of securities with a
simultaneous commitment to resell the securities to the bank or the dealer at an
agreed-upon date and price. A repurchase agreement is accounted for as an
investment by the Master Portfolio, collateralized by securities, which are
delivered to the Master Portfolio's custodian, or to an agent bank under a
tri-party agreement. The securities are marked-to-market daily and additional
securities are acquired as needed, to ensure that their value equals or exceeds
the repurchase price plus accrued interest.

     The repurchase agreements held by the Master Portfolio at December 31, 2003
were fully collateralized by U.S. Government and Agency obligations as follows:

                                                                    AGGREGATE

     MIP has entered into an administration services arrangement with BGI who
has agreed to provide general administration services, such as managing and
coordinating third-party service relationships, to the Master Portfolio. BGI is
not entitled to compensation for providing administration services to the Master
Portfolio, for so long as BGI is entitled to compensation for providing
administration services to corresponding feeder funds that invest substantially
all of their assets in the Master Portfolio, or BGI (or an affiliate) receives
advisory fees from the Master Portfolio. BGI may delegate certain of its
administration duties to sub-administrators. Prior to April 1, 2003, BGI and
Stephens Inc. jointly served as co-administrators for the Master Portfolio.

     Certain officers and trustees of MIP are also officers or employees of BGI.
As of December 31, 2003, these officers or employees of BGI collectively owned
less than 1% of MIP's outstanding beneficial interests.

REPORT OF INDEPENDENT AUDITORS

To the Interestholders and Board of Trustees of
Master Investment Portfolio:

     In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of operations
and of changes in net assets present fairly, in all material respects, the
financial position of the Money Market Master Portfolio, a portfolio of Master
Investment Portfolio (the "Portfolio"), at December 31, 2003, 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 three years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Portfolio's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with auditing standards generally accepted in the United States of America,
which require that we plan and perform the audits to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit 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, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 2003 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

     The financial highlights of the Portfolio for each of the periods ended
from February 28, 1999 through December 31, 2000 were audited by other auditors,
whose report dated February 9, 2001 expressed an unqualified opinion on those
highlights.

Item 2. Code of Ethics.

executive officer and senior financial officers (the "Code").

(b) No disclosures are required by this Item 2(b).

(c) During the period covered by the report, registrant did not make any
amendments to the provisions of the Code.

(d) During the period covered by the report, registrant did not grant any
waivers, including implicit waivers, from the provisions of the Code.

(f) A copy of the Code is filed as Exhibit (a)(1) to this Form N-CSR.

Item 3. Audit Committee Financial Expert.

Registrant's board of trustees has determined that John Oliverio, a member of
its audit committee, qualifies as an "audit committee financial expert," as such
term is defined in Instruction 2(b) to Item 3 of Form N-CSR. Mr. Oliverio is an
independent trustee.

Under applicable securities laws, a person who is determined to be an audit

including without limitation for the purposes of Section 11 of the Securities
Act of 1933, as a result of being designated or identified as an audit committee
financial expert. The designation or identification of a person as an audit
committee financial expert does not impose on such person any duties,
obligations, or liabilities that are greater than the duties, obligations, and
liabilities imposed on such person as a member of the audit committee and board
of trustees in the absence of such designation or identification.

owned Saratoga Institute database of human capital metrics.

(e) (1) Registrant's audit committee meets with the principal accountants and
management to review and pre-approve all audit services to be provided by the
principal accountants.

The audit committee shall pre-approve all non-audit services to be provided by
the principal accountants to the registrant; provided that the pre-approval
