Brown Brothers Harriman & Co. provides four funds for investor's liquid
assets. They range from a U.S Treasury Fund with maximum safety of principal to
a Tax Free Short/Intermediate Fixed Income Fund that has potential for price
volatility.

The net asset value of shares of each of the Money Market Fund, the U.S.
Treasury Money Fund and the Tax Exempt Money Fund is expected to remain constant
at $1.00 by investing in securities with a maturity of 13 months or less, and by
maintaining a dollar-weighted average maturity of 90 days or less. The share
price of the Tax Free Short/Intermediate Fixed Income Fund changes daily based
on market conditions.

consistent with the preservation of capital and the maintenance of liquidity.
The investment objective of the Tax Exempt Money Fund is to provide investors
with as high a level of current income exempt from federal income taxes as is
consistent with the preservation of capital and the maintenance of liquidity.
The investment objective of the Tax Free Short/Intermediate Fixed Income Fund is
to provide investors with as high a level of income exempt from federal income
tax as is consistent with minimizing price fluctuations in net asset value and
maintaining liquidity.

INVESTMENT STRATEGIES
------------------------------------------------------------------------------
U.S. Treasury Money Fund

The Investment Adviser of the U.S. Treasury Money Fund invests only in
securities backed as to principal and interest payments by the full faith and
credit of the United States of America. These securities are issues of the U.S.
Treasury, such as bills, notes and bonds as well as other full faith and credit
obligations of the U.S. Government.

<PAGE>

Money Market Fund

The Money Market Fund invests all of its assets in the U.S. Money Market
Portfolio, an investment company that has the same objective as the Fund. The
Investment Adviser of the Portfolio invests only in the highest rated,
short-term money market instruments denominated in U.S. dollars. These
instruments include U.S. Government securities and bank obligations of U.S. and
non-U.S. banks (such as certificates of deposit, fixed time deposits and
bankers' acceptances), commercial paper, repurchase agreements, reverse
repurchase agreements, when-issued and delayed delivery securities, bonds issued
by U.S. corporations and obligations of certain supranational organizations.

Tax Exempt Money Fund

The Investment Adviser invests at least 80% of the Fund's assets in
municipal securities the interest on which is exempt from federal income tax and
alternative minimum tax. Municipal securities may be fully or partially
guaranteed. They may be guaranteed by the local government or by the credit of a
private issuer. Municipal securities may also be guaranteed by the current or
anticipated revenues from a specific project or specific assets. Additionally,
municipal securities may be guaranteed by domestic or foreign entities providing
credit support such as letters of credit, guarantees or insurance. The
Investment Adviser may invest more than 25% of the Fund's total assets in
securities that finance similar projects, such as those relating to education,
health care, transportation and utilities.

Tax Free Short/Intermediate Fixed Income Fund

The Tax Free Short/Intermediate Fixed Income Fund invests primarily in a
broad range of high quality municipal securities issued by or on behalf of
states, territories and possessions of the United States, the District of
Columbia and their subdivisions, agencies and instrumentalities. These
securities include municipal bonds, notes, commercial paper, variable and
floating rate instruments and when-issued and delayed delivery securities. The
dollar weighted average maturity of the Fund's portfolio does not exceed three
years.

PRINCIPAL RISK FACTORS
----------------------------------------------------------------------------
The principal risks of investing in each Fund are described below. A
shareholder may lose money by investing in the Funds. Market Risk, Interest Rate
Risk and Credit Risk discussed below are applicable to each Fund and the
Portfolio.

o Market Risk:

The price of a debt security will fluctuate in response to changes in
interest rates.

<PAGE>

o Interest Rate Risk:

The amount of income paid to the shareholder by each Fund will fluctuate
depending on day-to-day variations in short-term interest rates. In general, the
prices of debt securities fall when interest rates rise. The Tax Free
Short/Intermediate Fixed Income Fund invests in longer term obligations which
are usually more sensitive to interest rate changes than the shorter-term
obligations in which the money market funds invest.

o Credit Risk:

Credit risk refers to the likelihood that an issuer will default on
interest or principal payments. Changes in the financial condition of an issuer,
changes in specific economic or political conditions that affect a particular
type of issuer, and changes in general economic or political conditions can
adversely affect the credit quality or value of an issuer's securities. Entities
providing credit support or a maturity-shortening structure also can be affected
by these types of changes. Municipal securities backed by current or anticipated
revenues from a specific project or specific assets can be negatively affected
by the discontinuance of the taxation supporting the project or assets or the
inability to collect revenues for the project or from the assets. If a
security's structure fails to function as intended, the security could become
taxable or decline in value. Because the Funds may invest their assets in
municipal securities of issuers financing similar type projects, the Funds may
be adversely affected by a particular economic or political event affecting that
type project. Because the U.S. Money Market Portfolio invests a significant
portion of its assets in bank obligations, the value of these investments and
the net assets of the Portfolio could decline more dramatically as a result of
adverse events affecting the bank industry.

Money Market Fund

o Foreign Investment Risk:

Because the U.S. Money Market Portfolio invests in securities issued by
non-U.S. banks, the Portfolio is subject to additional risks on these securities
such as adverse political, social and economic developments abroad, different
kinds and levels of market and issuer regulations and the different
characteristics of overseas economies and markets. There may be rapid changes in
the values of these securities.

Investments in each Fund are neither insured nor guaranteed by the U.S.
Government. Shares of each Fund are not deposits or obligations of, or
guaranteed by, Brown Brothers Harriman & Co. or any other bank, and the shares
are not insured by the Federal Deposit Insurance Corporation, the Federal
Reserve Board or any other federal, state or other governmental agency. Although
the Money Market Fund, U.S. Treasury Money Fund and Tax Exempt Money Fund seek
to preserve the value of your investment at $1.00 per share, it is possible to
lose money by investing in each Fund.

<PAGE>

Fund Performance
--------------------------------------------------------------------------------

The chart and table below give an indication of the risks of investing in
the Money Market Fund, U.S. Treasury Money Fund and Tax Free Short/Intermediate
Fixed Income Fund. The chart shows changes in each Fund's performance from year
to year. The table shows how the Tax Free Short/Intermediate Fixed Income Fund's
average annual returns for the periods indicated compared to those of a broad
measure of market performance. The US Money Market Fund provided shareholders
greater return than the US Treasury Money Fund with the same volatility. The US
Treasury Fund, however, is the safest credit risk. The return on the Tax Free
Short/Intermediate Fixed Income Fund is generally free from Federal income
taxes, while the returns on the Money Market Fund and U.S. Treasury Money Fund
are subject to Federal income taxes. For current yield information, please call
800-625-5759 toll free, or contact your account representative.

When you consider this information, please remember that a Fund's
performance in past years is not an indication of how a Fund will do in the
future.

Since the Tax Exempt Money Fund has not been in existence for a full
calendar year, bar chart and table information is not included.

EXAMPLE

The example is intended to help an investor compare the cost of investing
in the Funds to the cost of investing in other mutual funds. The example assumes
that an investor invests $10,000 in the Funds for the time periods indicated and
then sells all of his shares at the end of those periods. The example also
assumes that an investment has a 5% return each year and that the Funds'
operating expenses remain the same as shown in the table above. Although actual
costs on an investor's investment may be higher or lower, based on these
assumptions the investor's costs would be:

SHAREHOLDER INFORMATION

NET ASSET VALUE

The Trust determines the net asset value of each Fund every day the New
York Stock Exchange is open for regular trading and the Federal Reserve banks
are open for business. The U.S. Treasury Money Fund and Tax Exempt Money Fund
each calculate their net asset value once daily at 12:00 P.M., New York time.
The BBH U.S. Money Market Portfolio and Tax Free Short/Intermediate Fixed Income
Fund each calculate their net asset value once daily at 4:00 P.M., New York
time. Net asset value is the value of a single share of a Fund.

It is anticipated that the net asset value per share of the Money Market
Fund, U.S. Treasury Money Fund and Tax Exempt Money Fund will remain constant at
$1.00. No assurance can be given that this goal can be achieved.

The Trust values the assets of the U.S. Treasury Money Fund, Tax Exempt
Money Fund and the Portfolio at amortized cost, which is approximately equal to
market value. The Trust values the assets in the Tax Free Short/Intermediate
Fixed Income Fund's portfolio on the basis of their market quotations and
valuations provided by independent pricing services. If quotations are not
readily available, the assets of the Tax Free Short/Intermediate Fixed Income
Fund are valued at fair value in accordance with procedures established by the
Trustees of the Trust.

PURCHASE OF SHARES

The Trust offers shares of each Fund on a continuous basis at its net
asset value without a sales charge. The Trust reserves the right to determine
the purchase orders for Fund shares that it will accept. Investors may purchase
shares on any day the net asset value is calculated if the Trust receives the
purchase order, including acceptable payment for such order, prior to such
calculation. The Trust then executes purchases of Fund shares at the net asset
value per share next determined. Shares of the Money Market Fund, U.S. Treasury
Money Fund and Tax Exempt Money Fund are entitled to dividends declared on the
day the Trust executes the purchase order on the books of the Trust. Shares of
the Tax Free Short/Intermediate Fixed Income Fund are entitled to dividends
declared on the next business day following the day the Trust executes the
purchase order on the books of the Trust.

An investor who has an account with an Eligible Institution or a Financial
Intermediary may place purchase orders for Fund shares through that Eligible
Institution or Financial Intermediary, which holds such shares in its name on
behalf of that customer pursuant to arrangements made between that customer and
that Eligible Institution or Financial Intermediary. Each Eligible Institution
and each Financial Intermediary may establish and amend from time to time a
minimum initial and a minimum subsequent purchase requirement for its customers.
Currently, such minimum purchase requirements range from $1,000 to $25,000. Each
Eligible Institution or Financial Intermediary arranges payment for Fund shares
on behalf of its customers. An Eligible Institution or a Financial Intermediary
may charge a transaction fee on the purchase of Fund shares.

An investor who does not have an account with an Eligible Institution or a
Financial Intermediary must place purchase orders for Fund shares with the Trust
through Forum Shareholder Services, LLC, the Funds' Transfer Agent. Such an
investor has such shares held directly in the investor's name on the books of
the Trust and is responsible for arranging for the payment of the purchase price
of Fund shares. The Trust executes all purchase orders for initial and
subsequent purchases at the net asset value per share next determined after the
Trust's Transfer Agent has received payment in the form of a cashier's check
drawn on a U.S. bank, a check certified by a U.S. bank or a wire transfer. Brown
Brothers Harriman & Co., the Funds' Shareholder Servicing Agent has established
a minimum initial purchase requirement for each Fund of $100,000 and a minimum
subsequent purchase requirement for each Fund of $25,000. The Shareholder
Servicing Agent may amend these minimum purchase requirements from time to time.

<PAGE>

REDEMPTION OF SHARES

The Trust executes your redemption request at the next net asset value
calculated after the Trust receives your redemption request. Shares of the Money
Market Fund, U.S. Treasury Money Fund and Tax Exempt Money Fund continue to earn
daily dividends declared prior to the business day that the Trust executes the
redemption request on the books of the Trust. Shares of the Tax Free
Short/Intermediate Fixed Income Fund continue to earn dividends declared through
the business day that the Trust executes the redemption request on the books of
the Trust.

Shareholders must redeem shares held by an Eligible Institution or a
Financial Intermediary on behalf of such shareholder pursuant to arrangements
made between that shareholder and that Eligible Institution or Financial
Intermediary. The Trust pays proceeds of a redemption to that shareholder's
account at that Eligible Institution or Financial Intermediary on a date
established by the Eligible Institution or Financial Intermediary. An Eligible
Institution or a Financial Intermediary may charge a transaction fee on the
redemption of Fund shares.

Shareholders may redeem shares held directly in the name of a shareholder
on the books of the Trust by submitting a redemption request in good order to
the Trust through the Shareholder Servicing Agent. The Trust pays proceeds
resulting from such redemption directly to shareholders of the Money Market
Fund, U.S. Treasury Money Fund and Tax Exempt Money Fund generally on the day
the redemption request is executed, and in any event within seven days. The
Trust pays proceeds resulting from such redemption directly to shareholders of
the Tax Free Short/Intermediate Fixed Income Fund generally on the next business
day after the redemption request is executed, and in any event within seven
days.

A shareholder redeeming shares should be aware that the net asset value of
the shares of the Money Market Fund, U.S. Treasury Money Fund and Tax Exempt
Money Fund may, in unusual circumstances, decline below $1.00 per share.
Accordingly, a redemption request may result in payment of a dollar amount which
differs from the number of shares redeemed.

Redemptions by the Trust

The Shareholder Servicing Agent has established a minimum account size of
$100,000 for the Funds, which may be amended from time to time. If the value of
a shareholder's holdings in a Fund falls below that amount because of a
redemption of shares, the Trust may redeem the shareholder's remaining shares.
If such remaining shares are to be redeemed, the Trust notifies the shareholder
and allows the shareholder 60 days to make an additional investment to meet the
minimum requirement before the redemption is processed. Each Eligible
Institution and each Financial Intermediary may establish and amend from time to
time for their respective customers a minimum account size, each of which is
currently lower than that established by the Shareholder Servicing Agent.

Further Redemption Information

Redemptions of shares are taxable events on which a shareholder may
realize a gain or a loss.

The Trust may suspend a shareholder's right to receive payment with
respect to any redemption or postpone the payment of the redemption proceeds for
up to seven days and for such other periods as applicable law may permit.
<PAGE>

Dividends and Distributions

The net income and short-term capital gains and losses of the Money Market
Fund, U.S. Treasury Money Fund and Tax Exempt Money Fund, if any, are declared
as a dividend daily and paid monthly. All of the Tax Free Short/Intermediate
Fixed Income Fund's net investment income and a discretionary portion of any net
short-term capital gains are declared as a dividend daily and paid monthly.

Determination of each Fund's net income is made each business day
immediately prior to the determination of the net asset value per share of each
Fund. Net income for days other than such business days is determined at the
time of the determination of the net asset value per share of each Fund on the
immediately preceding business day.

Each Eligible Institution and each Financial Intermediary may establish
its own policy with respect to the reinvestment of dividends in additional Fund
shares.

Dividends declared are payable to shareholders of record of the Funds
on the date of determination. For the U.S. Treasury Money Fund and Tax Exempt
Money Fund, shares purchased through submission of a purchase order prior to
12:00 P.M., New York time on such a business day begin earning dividends on that
business day. For the Money Market Fund shares purchased through submission of a
purchase order prior to 4:00 P.M., New York time on such a business day begin
earning dividends on that business day. Shares redeemed do not qualify for a
dividend on the business day that the redemption is executed. For the Tax Free
Short/Intermediate Fixed Income Fund shares purchased through submission of a
purchase order prior to 4:00 P.M., New York time on such a business day begin
earning dividends on the next business day. Shares redeemed do qualify for a
dividend on the business day that the redemption is executed. Unless a
shareholder whose shares are held directly in the shareholder's name on the
books of the Trust elects to have dividends paid in cash, the Trust
automatically reinvests dividends in additional Fund shares without reference to
the minimum subsequent purchase requirement.

Such shareholder who elects to have dividends paid in cash receives a
check in the amount of such dividends. In the event a shareholder redeems all
shares held at any time during the month, all accrued but unpaid dividends are
included in the proceeds of the redemption and future purchases of shares by
such shareholder will be subject to the minimum initial purchase requirements.

Substantially all of the Tax Free Short/Intermediate Fixed Income Fund's
realized net long-term capital gains, if any, are declared and paid to
shareholders on an annual basis as a capital gains distribution. The Trust may
make an additional dividend and/or capital gains distribution in a given year to
the extent necessary to avoid the imposition of federal excise tax on the Fund.

Taxes

Dividends of net income and net short-term capital gains, if any, are
taxable to shareholders of the Money Market Fund and U.S. Treasury Money Fund as
ordinary income, whether such dividends are paid in cash or reinvested in
additional shares.

The Tax Exempt Money Fund and the Tax Free Short/Intermediate Fixed Income
Fund expect that most of their net income will be attributable to interest on
municipal obligations and as a result most of the Funds' dividends to
shareholders will not be taxable. The non-exempt portion of dividends are
taxable to shareholders of the Funds as ordinary income, whether such dividends
are paid in cash or reinvested in additional shares.

The Tax Free Short/Intermediate Fixed Income Fund's capital gains may be
taxable at different rates depending on the length of time the Fund holds its
assets. Capital gains distributions are taxable to shareholders as long-term
capital gains, whether paid in cash or reinvested in additional shares and
regardless of the length of time a particular shareholder has held Fund shares.

The treatment of each Fund and its shareholders in those states which have
income tax laws might differ from treatment under the federal income tax laws.
Therefore, distributions to shareholders may be subject to additional state and
local taxes. Shareholders are urged to consult their tax advisors regarding any
state or local taxes.

Foreign Investors

Each Fund is designed for investors who are either citizens of the United
States or aliens subject to United States income tax. Prospective investors who
are not citizens of the United States and who are not aliens subject to United
States income tax are subject to United States withholding tax on the entire
amount of all dividends. Therefore, such investors should not invest in the
Funds since alternative investments would not be subject to United States
withholding tax.

FINANCIAL HIGHLIGHTS
--------------------------------------------------------------------------------

The financial highlights table is intended to help an investor understand
the financial performance of the Funds. Certain information reflects financial
results for a single Fund share. The total returns in the tables represent the
rate that an investor would have earned on an investment in each Fund (assuming
reinvestment of all dividends and distributions). This information has been
audited by Deloitte & Touche LLP, whose report, along with the Funds' financial
statements, are included in the annual report, which is available upon request.

ADDITIONAL INVESTMENT INFORMATION

Money Market Fund

Investment Structure. The Trust seeks to achieve the investment objective
of the Money Market Fund by investing all of the Fund's assets in the Portfolio,
a diversified open-end investment company having the same investment objective
as the Fund. Other mutual funds or institutional investors may invest in the
Portfolio on the same terms and conditions as the Fund. However, these other
investors may have different operating expenses which may generate different
aggregate performance results. The Trust may withdraw the Fund's investment in
the Portfolio at any time as a result of changes in the Portfolio's investment
objective, policies or restrictions or if the Board of Trustees determines that
it is otherwise in the best interests of the Fund to do so.

U.S. Government Securities. The Portfolio may invest in securities issued
or guaranteed by the U.S. Government, its agencies or instrumentalities. These
securities, including those which are guaranteed by federal agencies or
instrumentalities, may or may not be backed by the "full faith and credit" of
the United States.

Bank Obligations. The Portfolio may invest in U.S. dollar-denominated high
quality securities. These securities include negotiable certificates of deposit,
fixed time deposits and bankers' acceptances of banks, savings and loan
associations and savings banks organized under the laws of the United States or
any state thereof. The Portfolio's investments also include obligations of
non-U.S. branches of such banks, or of non-U.S. banks or their U.S. or non-U.S.
branches. (The Portfolio may only invest in obligations of such non-U.S. banks
if such bank has more than $500 million in total assets, and has an outstanding
short-term debt issue rated within the highest rating category for short-term
debt obligations by at least two (unless only rated by one) nationally
recognized statistical rating organizations (e.g., Moody's and S&P). The
Portfolio may invest in unrated obligations of non-U.S. banks if such
obligations are of comparable quality as determined by or under the direction of
the Portfolio's Board of Trustees.)

Commercial Paper. The Portfolio may invest in commercial paper including
variable rate demand master notes issued by U.S. corporations or by non-U.S.
corporations which are direct parents or subsidiaries of U.S. corporations.
Master notes are demand obligations that permit the investment of fluctuating
amounts at varying market rates of interest pursuant to arrangements between the
issuer and a U.S. commercial bank acting as agent for the payees of such notes.
Master notes are callable on demand, but are not marketable to third parties.
Consequently, the right to redeem such notes depends on the borrower's ability
to pay on demand. At the date of investment, commercial paper must be rated
within the highest rating category for short-term debt obligations by at least
two (unless only rated by one) nationally recognized statistical rating
organizations (e.g., Moody's and S&P) or, if unrated, are of comparable quality
as determined by or under the direction of the Portfolio's Board of Trustees.

Repurchase Agreements. The Portfolio may enter into repurchase agreements
for the Portfolio only with a "primary dealer" (as designated by the Federal
Reserve Bank of New York) in U.S. Government securities. A repurchase agreement
is an agreement in which the seller (the Lender) of a security agrees to
repurchase from the Portfolio the security sold at a mutually agreed upon time
and price. As such, it is viewed as the lending of money to the Lender. The
Portfolio always receives as collateral securities which are issued or
guaranteed by the U.S. Government, its agencies or instrumentalities.

Other Obligations. Assets of the Portfolio may be invested in bonds, with
maturities not exceeding one year, issued by U.S. corporations which at the date
of investment are rated within the highest rating category for such obligations
by at least two (unless only rated by one) nationally recognized statistical
rating organizations (e.g., Moody's and S&P) or, if unrated, are of comparable
quality as determined by or under the direction of the Portfolio's Board of
Trustees.

Assets of the Portfolio may also be invested in obligations of the
International Bank for Reconstruction and Development which may be supported by
appropriated but unpaid commitments of its member countries, although there is
no assurance that these commitments will be undertaken in the future. However,
assets of the Portfolio may not be invested in obligations of the Inter-American
Development Bank or the Asian Development Bank.

BBH U.S. Money Market Portfolio, U.S. Treasury

Money Fund and Tax Exempt Money Fund

The Investment Adviser invests all of the assets of the BBH U.S. Money
Market Portfolio, U.S. Treasury Money Fund and Tax Exempt Money Fund in
securities which are rated within the highest rating category for short-term
debt obligations by at least two (unless only rated by one) nationally
recognized statistical rating organizations (e.g., Moody's Investors Service,
Inc., Standard & Poor's Corporation and Fitch or, if unrated, are of comparable
quality as determined by or under the direction of the Board of Trustees of the
Fund and the Portfolio.

Tax Exempt Money Fund and Tax Free Short/
Intermediate Fixed Income Fund

The following information describes the securities each Fund may purchase,
the interest on which is exempt from federal income tax and the alternative
minimum tax. However, other such securities not mentioned below may be purchased
for each Fund if they meet the quality and maturity guidelines set forth in each
Fund's investment policies.

Municipal Bonds. Municipal securities are issued to raise money for a
variety of public and private purposes, including general financing for state
and local governments, or financing for a specific project or public facility.
Municipal securities provide interest income that is exempt from regular federal
income tax, other than the alternative minimum tax. They generally meet the
longer-term capital needs of their issuers and have maturities of one year or
more. The Tax Exempt Money Funds may purchase Municipal Bonds with a remaining
maturity of 397 days or less. These securities include:

o General Obligation Bonds--bonds backed by the municipality's pledge
of full faith, credit and taxing power.

o Revenue Bonds--bonds backed by the revenue of a specific project,
facility or tax. These include municipal water, sewer and power
utilities; transportation projects; education or housing facilities;
industrial development and resource recovery bonds.

o Refunded Bonds--general obligation or revenue bonds that have been
fully secured or collateralized by an "escrow fund" consisting of
U.S. Government obligations that can adequately meet interest and
principal payments.

o Lease Obligation Bonds--bonds backed by lease obligations of a state
or local authority for the use of land, equipment and facilities.
These securities are not backed by the full faith and credit of the
municipality and may be riskier than general obligation bonds or
revenue bonds.

o Asset-Backed Bonds--bonds secured by interests in pools of municipal
purchase contracts, financing leases and sales agreements. These
obligations are collateralized by the assets purchased or leased by
the municipality.

o Zero Coupon Bonds--securities issued at a discount from their face
value that pay all interest and principal upon maturity.

o Participation Certificates--variable rate demand instruments that
the Tax Exempt Money Fund may invest in include Participation
Certificates purchased by such Fund from banks, insurance companies
or other financial institutions in fixed or variable rate,
tax-exempt municipal obligations (expected to be focused in
Revenue Bonds) owned by such institutions or affiliated
organizations. A participation certificate represents the sale
by the bank of an undivided interest in a municipal obligation it
owns. These certificates may be supported by a bank letter of
credit or guarantee.
<PAGE>

Other Federal Tax-Exempt Obligations--Any other Federal tax-exempt
obligations issued by or on behalf of states and municipal governments and their
authorities, agencies, instrumentalities and political subdivisions, whose
inclusion in the Tax Exempt Money Fund would be consistent with such Fund's
Investment Objectives, Investment Strategies, and permissable under Rule 2a-7
under the Investment Company Act of 1940 as amended.

Stand-by Commitments--When the Tax Exempt Money Fund purchases Municipal
Obligations it may also acquire stand-by commitments from banks and other
financial institutions with respect to such Municipal Obligations. Under a
stand-by commitment, a bank or broker-dealer agrees to purchase at such Fund's
option a specified Municipal Obligation at a specified price with same day
settlement.

Municipal Notes. Debt obligations issued by states, local governments and
regional authorities which provide interest income that is exempt from regular
federal income taxes, other than the alternative minimum tax. They generally
meet the shorter-term capital needs of their issuers and have maturities of less
than one year. These securities include:

o Tax and Revenue Anticipation Notes--notes issued in expectation of
future taxes or revenues.

o Bond Anticipation Notes--notes issued in anticipation of the sale of
long-term bonds.

Municipal Commercial Paper--obligations issued to meet short-term working
capital or operating needs.

Variable and Floating Rate Instruments--securities whose interest rates
are reset daily, weekly or at another periodic date so that the security remains
close to par, minimizing changes in its market value. These securities often
have a demand feature which entitles the investor to repayment of principal plus
accrued interest on short notice.

STATEMENT OF ADDITIONAL INFORMATION
THE 59 WALL STREET MONEY MARKET FUND

21 Milk Street, Boston, Massachusetts 02109

The 59 Wall Street Money Market Fund (the "Fund") is a separate
portfolio of The 59 Wall Street Trust (the "Trust"), a management investment
company registered under the Investment Company Act of 1940, as amended (the
"1940 Act"). The Fund is a type of mutual fund commonly known as a money market
fund. The Fund is designed to be a cost effective and convenient means of making
substantial investments in money market instruments. The investment objective of
the Fund is to achieve as high a level of current income as is consistent with
the preservation of capital and the maintenance of liquidity. The Trust seeks to
achieve the investment objective of the Fund by investing all of the Fund's
assets in the BBH U.S. Money Market Portfolio (the "Portfolio"), a diversified
open-end investment company having the same investment objective as the Fund.
The Portfolio pursues its investment objective by investing in high quality,
short-term money market instruments. There can be no assurance that the Fund's
investment objective will be achieved.

Brown Brothers Harriman & Co. is the investment adviser of the
Portfolio (the "Investment Adviser"). This Statement of Additional Information
is not a prospectus and should be read in conjunction with the Prospectus dated
November 1, 1999, as supplemented July 1, 2000, a copy of which may be obtained
from the Trust at the address noted above.

INVESTMENT OBJECTIVE AND POLICIES

The following supplements the information contained in the Prospectus
concerning the investment objective, policies and techniques of the Fund and the
Portfolio. Since the investment characteristics of the Fund correspond directly
to those of the Portfolio, the following is a discussion of the various
investments and investment policies of the Portfolio.

Loans of Portfolio Securities

Loans of portfolio securities up to 30% of the total value of the
Portfolio are permitted and may be entered into for not more than one year.
Securities of the Portfolio may be loaned if such loans are secured continuously
by cash or equivalent collateral or by an irrevocable letter of credit in favor
of the Portfolio at least equal at all times to 100% of the market value of the
securities loaned plus accrued income. While such securities are on loan, the
borrower pays the Portfolio any income accruing thereon, and cash collateral may
be invested for the Portfolio, thereby earning additional income. All or any
portion of interest earned on invested collateral may be paid to the borrower.
Loans are subject to termination by the Portfolio in the normal settlement time,
currently three business days after notice, or by the borrower on one day's
notice. Borrowed securities are returned when the loan is terminated. Any
appreciation or depreciation in the market price of the borrowed securities
which occurs during the term of the loan inures to the Portfolio and its
investors. Reasonable finders' and custodial fees may be paid in connection with
a loan. In addition, all facts and circumstances, including the creditworthiness
of the borrowing financial institution, are considered before a loan is made and
no loan is made in excess of one year. There is the risk that a borrowed
security may not be returned to the Portfolio. Securities of the Portfolio are
not loaned to Brown Brothers Harriman & Co. or to any affiliate of the Trust,
the Portfolio or Brown Brothers Harriman & Co.

U.S. Government Securities

Assets of the Portfolio may be invested in securities issued or
guaranteed by the U.S. Government, its agencies or instrumentalities. These
securities, including those which are guaranteed by federal agencies or
instrumentalities, may or may not be backed by the "full faith and credit" of
the United States. In the case of securities not backed by the full faith and
credit of the United States, it may not be possible to assert a claim against
the United States itself in the event the agency or instrumentality issuing or
guaranteeing the security for ultimate repayment does not meet its commitments.
Securities which are not backed by the full faith and credit of the United
States include, but are not limited to, securities of the Tennessee Valley
Authority, the Federal National Mortgage Association (FNMA), the U.S. Postal
Service and the Resolution Funding Corporation (REFCORP), each of which has a
limited right to borrow from the U.S. Treasury to meet its obligations, and
securities of the Federal Farm Credit System, the Federal Home Loan Banks, the
Federal Home Loan Mortgage Corporation (FHLMC) and the Student Loan Marketing
Association, the obligations of each of which may be satisfied only by the
individual credit of the issuing agency. Securities which are backed by the full
faith and credit of the United States include Treasury bills, Treasury notes,
Treasury bonds and pass through obligations of the Government National Mortgage
Association (GNMA), the Farmers Home Administration and the Export-Import Bank.
There is no percentage limitation with respect to investments in U.S. Government
securities.

Bank Obligations

Assets of the Portfolio may be invested in U.S. dollar-denominated
negotiable certificates of deposit, fixed time deposits and bankers' acceptances
of banks, savings and loan associations and savings banks organized under the
laws of the United States or any state thereof, including obligations of
non-U.S. branches of such banks, or of non-U.S. banks or their U.S. or non-U.S.
branches, provided that in each case, such bank has more than $500 million in
total assets, and has an outstanding short-term debt issue rated within the
highest rating category for short-term debt obligations by at least two (unless
only rated by one) nationally recognized statistical rating organizations (e.g.,
Moody's and S&P) or, if unrated, are of comparable quality as determined by or
under the direction of the Portfolio's Board of Trustees. See "Bond, Note and
Commercial Paper Ratings" in the Statement of Additional Information. There is
no additional percentage limitation with respect to investments in negotiable
certificates of deposit, fixed time deposits and bankers' acceptances of U.S.
branches of U.S. banks and U.S. branches of non-U.S. banks that are subject to
the same regulation as U.S. banks. Since the Portfolio may contain U.S.
dollar-denominated certificates of deposit, fixed time deposits and bankers'
acceptances that are issued by non-U.S. banks and their non-U.S. branches, the
Portfolio may be subject to additional investment risks with respect to those
securities that are different in some respects from obligations of U.S. issuers,
such as currency exchange control regulations, the possibility of expropriation,
seizure or nationalization of non-U.S. deposits, less liquidity and more
volatility in non-U.S. securities markets and the impact of political, social or
diplomatic developments or the adoption of other foreign government restrictions
which might adversely affect the payment of principal and interest on securities
held by the Portfolio. If it should become necessary, greater difficulties might
be encountered in invoking legal processes abroad than would be the case in the
United States. Issuers of non-U.S. bank obligations may be subject to less
stringent or different regulations than are U.S. bank issuers, there may be less
publicly available information about a non-U.S. issuer, and non-U.S. issuers
generally are not subject to uniform accounting and financial reporting
standards, practices and requirements comparable to those applicable to U.S.
issuers. Income earned or received by the Portfolio from sources within
countries other than the United States may be reduced by withholding and other
taxes imposed by such countries. Tax conventions between certain countries and
the United States, however, may reduce or eliminate such taxes. All such taxes
paid by the Portfolio would reduce its net income available for distribution to
investors (i.e., the Fund and other investors in the Portfolio); however, the
Investment Adviser would consider available yields, net of any required taxes,
in selecting securities of non-U.S. issuers. While early withdrawals are not
contemplated, fixed time deposits are not readily marketable and may be subject
to early withdrawal penalties, which may vary. Assets of the Portfolio are not
invested in obligations of Brown Brothers Harriman & Co., or the Distributor, or
in the obligations of the affiliates of any such organization. Assets of the
Portfolio are also not invested in fixed time deposits with a maturity of over
seven calendar days, or in fixed time deposits with a maturity of from two
business days to seven calendar days if more than 10% of the Portfolio's net
assets would be invested in such deposits.

Commercial Paper

Assets of the Portfolio may be invested in commercial paper including
variable rate demand master notes issued by U.S. corporations or by non-U.S.
corporations which are direct parents or subsidiaries of U.S. corporations.
Master notes are demand obligations that permit the investment of fluctuating
amounts at varying market rates of interest pursuant to arrangements between the
issuer and a U.S. commercial bank acting as agent for the payees of such notes.
Master notes are callable on demand, but are not marketable to third parties.
Consequently, the right to redeem such notes depends on the borrower's ability
to pay on demand. At the date of investment, commercial paper must be rated
within the highest rating category for short-term debt obligations by at least
two (unless only rated by one) nationally recognized statistical rating
organizations (e.g., Moody's and S&P) or, if unrated, are of comparable quality
as determined by or under the direction of the Portfolio's Board of Trustees.
Any commercial paper issued by a non-U.S. corporation must be U.S.
dollar-denominated and not subject to non-U.S. withholding tax at the time of
purchase. Aggregate investments in non-U.S. commercial paper of non-U.S. issuers
cannot exceed 10% of the Portfolio's net assets. Since the Portfolio may contain
commercial paper issued by non-U.S. corporations, it may be subject to
additional investment risks with respect to those securities that are different
in some respects from obligations of U.S. issuers, such as currency exchange
control regulations, the possibility of expropriation, seizure or
nationalization of non-U.S. deposits, less liquidity and more volatility in
non-U.S. securities markets and the impact of political, social or diplomatic
developments or the adoption of other foreign government restrictions which
might adversely affect the payment of principal and interest on securities held
by the Portfolio. If it should become necessary, greater difficulties might be
encountered in invoking legal processes abroad than would be the case in the
United States. There may be less publicly available information about a non-U.S.
issuer, and non-U.S. issuers generally are not subject to uniform accounting and
financial reporting standards, practices and requirements comparable to those
applicable to U.S. issuers.

Repurchase Agreements

Repurchase agreements may be entered into for the Portfolio only with a
"primary dealer" (as designated by the Federal Reserve Bank of New York) in U.S.
Government securities. This is an agreement in which the seller (the "Lender")
of a security agrees to repurchase from the Portfolio the security sold at a
mutually agreed upon time and price. As such, it is viewed as the lending of
money to the Lender. The resale price normally is in excess of the purchase
price, reflecting an agreed upon interest rate. The rate is effective for the
period of time assets of the Portfolio are invested in the agreement and is not
related to the coupon rate on the underlying security. The period of these
repurchase agreements is usually short, from overnight to one week, and at no
time are assets of the Portfolio invested in a repurchase agreement with a
maturity of more than one year. The securities which are subject to repurchase
agreements, however, may have maturity dates in excess of one year from the
effective date of the repurchase agreement. The Portfolio always receives as
collateral securities which are issued or guaranteed by the U.S. Government, its
agencies or instrumentalities. Collateral is marked to the market daily and has
a market value including accrued interest at least equal to 100% of the dollar
amount invested on behalf of the Portfolio in each agreement along with accrued
interest. Payment for such securities is made for the Portfolio only upon
physical delivery or evidence of book entry transfer to the account of Brown
Brothers Harriman & Co, the Portfolio's Custodian. If the Lender defaults, the
Portfolio might incur a loss if the value of the collateral securing the
repurchase agreement declines and might incur disposition costs in connection
with liquidating the collateral. In addition, if bankruptcy proceedings are
commenced with respect to the Lender, realization upon the collateral on behalf
of the Portfolio may be delayed or limited in certain circumstances. A
repurchase agreement with more than seven days to maturity may not be entered
into for the Portfolio if, as a result, more than 10% of the Portfolio's net
assets would be invested in such repurchase agreement together with any other
investment for which market quotations are not readily available.

Reverse Repurchase Agreements

Reverse repurchase agreements may be entered into only with a "primary
dealer" (as designated by the Federal Reserve Bank of New York) in U.S.
Government securities. This is an agreement in which the Portfolio agrees to
repurchase securities sold by it at a mutually agreed upon time and price. As
such, it is viewed as the borrowing of money for the Portfolio. Proceeds of
borrowings under reverse repurchase agreements are invested for the Portfolio.
This is the speculative factor known as "leverage". If interest rates rise
during the term of a reverse repurchase agreement utilized for leverage, the
value of the securities to be repurchased for the Portfolio as well as the value
of securities purchased with the proceeds will decline. In these circumstances,
the Portfolio's entering into reverse repurchase agreements may have a negative
impact on the ability to maintain the Fund's net asset value of $1.00 per share.
Proceeds of a reverse repurchase transaction are not invested for a period which
exceeds the duration of the reverse repurchase agreement. A reverse repurchase
agreement is not entered into for the Portfolio if, as a result, more than
one-third of the market value of the Portfolio's total assets, less liabilities
other than the obligations created by reverse repurchase agreements, is engaged
in reverse repurchase agreements. In the event that such agreements exceed, in
the aggregate, one-third of such market value, the amount of the Portfolio's
obligations created by reverse repurchase agreements is reduced within three
days thereafter (not including weekends and holidays) or such longer period as
the Securities and Exchange Commission may prescribe, to an extent that such
obligations do not exceed, in the aggregate, one-third of the market value of
the Portfolio's assets, as defined above. A segregated account with the
Custodian is established and maintained for the Portfolio with liquid assets in
an amount at least equal to the Portfolio's purchase obligations under its
reverse repurchase agreements. Such a segregated account consists of liquid high
grade debt securities marked to the market daily, with additional liquid assets
added when necessary to insure that at all times the value of such account is
equal to the purchase obligations.

When-Issued and Delayed Delivery Securities

Securities may be purchased for the Portfolio on a when-issued or delayed
delivery basis. For example, delivery and payment may take place a month or more
after the date of the transaction. The purchase price and the interest rate
payable on the securities are fixed on the transaction date. The securities so
purchased are subject to market fluctuation and no interest accrues to the
Portfolio until delivery and payment take place. At the time the commitment to
purchase securities for the Portfolio on a when-issued or delayed delivery basis
is made, the transaction is recorded and thereafter the value of such securities
is reflected each day in determining the Portfolio's net asset value. At the
time of its acquisition, a when-issued security may be valued at less than the
purchase price. Commitments for such when-issued securities are made only when
there is an intention of actually acquiring the securities. To facilitate such
acquisitions, a segregated account with the Custodian is maintained for the
Portfolio with liquid assets in an amount at least equal to such commitments.
Such a segregated account consists of liquid high grade debt securities marked
to the market daily, with additional liquid assets added when necessary to
insure that at all times the value of such account is equal to the commitments.
On delivery dates for such transactions, such obligations are met from
maturities or sales of the securities held in the segregated account and/or from
cash flow. If the right to acquire a when-issued security is disposed of prior
to its acquisition, the Portfolio could, as with the disposition of any other
portfolio obligation, incur a gain or loss due to market fluctuation.
When-issued commitments for the Portfolio may not be entered into if such
commitments exceed in the aggregate 15% of the market value of the Portfolio's
total assets, less liabilities other than the obligations created by when-issued
commitments.

Other Obligations

Assets of the Portfolio may be invested in bonds, with maturities not
exceeding one year, issued by U.S. corporations which at the date of investment
are rated within the highest rating category for such obligations by at least
two (unless only rated by one) nationally recognized statistical rating
organizations (e.g., Moody's and S&P) or, if unrated, are of comparable quality
as determined by or under the direction of the Portfolio's Board of Trustees.

INVESTMENT RESTRICTIONS

The Fund and the Portfolio are operated under the following investment
restrictions which are deemed fundamental policies and may be changed only with
the approval of the holders of a "majority of the outstanding voting securities"
(as defined in the 1940 Act) of the Fund or the Portfolio, as the case may be
(see "Additional Information"). Since the investment restrictions of the Fund
correspond directly to those of the Portfolio, the following is a discussion of
the various investment restrictions of the Portfolio.
As a fundamental policy, money is not borrowed by the Portfolio in an
amount in excess of 10% of its assets. It is intended that money will be
borrowed only from banks and only either to accommodate requests for the
withdrawal of part or all of an interest while effecting an orderly liquidation
of portfolio securities or to maintain liquidity in the event of an
unanticipated failure to complete a portfolio security transaction or other
similar situations. Securities are not purchased for the Portfolio at any time
at which the amount of its borrowings exceed 5% of its net assets.

Except that the Trust may invest all of the Fund's assets in an
open-end investment company with substantially the same investment objective,
policies and restrictions as the Fund, neither the Portfolio nor the Trust, with
respect to the Fund, may:

(1) purchase securities which may not be resold to the public without
registration under the Securities Act of 1933, as amended;

(2) enter into repurchase agreements with more than seven days to
maturity if, as a result thereof, more than 10% of the market value of its net
assets would be invested in such repurchase agreements together with any other
investment for which market quotations are not readily available;

(3) enter into reverse repurchase agreements which, including any
borrowings under Investment Restriction No. 4, exceed, in the aggregate,
one-third of the market value of its total assets, less liabilities other than
obligations created by reverse repurchase agreements. In the event that such
agreements exceed, in the aggregate, one-third of such market value, it will,
within three days thereafter (not including weekends and holidays) or such
longer period as the Securities and Exchange Commission may prescribe, reduce
the amount of the obligations created by reverse repurchase agreements to an
extent that such obligations will not exceed, in the aggregate, one-third of the
market value of its assets;

(4) borrow money, except from banks for extraordinary or emergency
purposes and then only in amounts not to exceed 10% of the value of its total
assets, taken at cost, at the time of such borrowing; mortgage, pledge or
hypothecate any assets except in connection with any such borrowing and in
amounts not to exceed 10% of the value of its net assets at the time of such
borrowing. Neither the Portfolio nor the Trust on behalf of the Fund, as the
case may be, will purchase securities while borrowings exceed 5% of its total
assets. This borrowing provision is included to facilitate the orderly sale of
portfolio securities, for example, in the event of abnormally heavy redemption
requests, and is not for investment purposes and does not apply to reverse
repurchase agreements (see "Other Investments - Reverse Repurchase Agreements");

(5) enter into when-issued commitments exceeding in the aggregate 15%
of the market value of its total assets, less liabilities other than obligations
created by when-issued commitments;

(6) purchase the securities or other obligations of issuers conducting
their principal business activity in the same industry if, immediately after
such purchase, the value of such investments in such industry would exceed 25%
of the value of its total assets. For purposes of industry concentration, there
is no percentage limitation with respect to investments in U.S. Government
securities and negotiable certificates of deposit, fixed time deposits and
bankers' acceptances of U.S. branches of U.S. banks and U.S. branches of
non-U.S. banks that are subject to the same regulation as U.S. banks;

(7) purchase the securities or other obligations of any one issuer if,
immediately after such purchase, more than 5% of the value of its total assets
would be invested in securities or other obligations or any one such issuer.
This limitation does not apply to issues of the U.S. Government, its agencies or
instrumentalities;

(8) make loans, except through the purchase or holding of debt
obligations, repurchase agreements or loans of portfolio securities in
accordance with its investment objective and policies (see "Investment Objective
and Policies");

(9) purchase or sell puts, calls, straddles, spreads, or any
combinations thereof; real estate; commodities; commodity contracts or interests
in oil, gas or mineral exploration or development programs. However, bonds or
commercial paper issued by companies which invest in real estate or interests
therein including real estate investment trusts may be purchased;

(10) purchase securities on margin, make short sales of securities or
maintain a short position, provided that this restriction is not deemed to be
applicable to the purchase or sale of when-issued securities or of securities
for delivery at a future date;

(11) invest in fixed time deposits with a duration of over seven
calendar days, or in fixed time deposits with a duration of from two business
days to seven calendar days if more than 10% of its total assets would be
invested in such deposits;

(12) acquire securities of other investment companies;

(13) act as an underwriter of securities; or

(14) issue any senior security (as that term is defined in the 1940
Act) if such issuance is specifically prohibited by the 1940 Act or the rules
and regulations promulgated thereunder.

Except with respect to Investment Restriction No. 3, there will be no
violation of any investment restriction if that restriction is complied with at
the time the relevant action is taken notwithstanding a later change in market
value of an investment, in net or total assets, in the securities rating of the
investment, or any other later change.

Non-Fundamental Restrictions. The Portfolio or the Trust, on behalf of
the Fund, may not as a matter of operating policy (except that the Trust may
invest all of the Fund's assets in an open-end investment company with
substantially the same investment objective, policies and restrictions as the
Fund): (i) purchase more than 10% of all outstanding debt obligations of any one
issuer (other than securities issued by the U.S. government, its agencies
instrumentalities); or (ii) invest more than 10% of its net assets (taken at the
greater of cost or market value) in restricted securities. These policies are
not fundamental and may be changed without shareholder or investor approval.

Percentage and Rating Restrictions. If a percentage or rating
restriction on investment or utilization of assets set forth above or referred
to in the Prospectus is adhered to at the time an investment is made or assets
are so utilized, a later change in percentage resulting from changes in the
value of the portfolio securities or a later change in the rating of a portfolio
security is not considered a violation of policy. If the Fund's and the
Portfolio's respective investment restrictions relating to any particular
investment practice or policy are not consistent, the Portfolio has agreed with
the Trust, on behalf of the Fund, that the Portfolio will adhere to the more
restrictive limitation.

The Fund is classified as "diversified" under the 1940 Act, which means
that at least 75% of its total assets is represented by cash; securities issued
by the U.S. Government, its agencies or instrumentalities; and other securities
limited in respect of any one issuer to an amount no greater than 5% of the
Fund's total assets (other than securities issued by the U.S. Government, its
agencies or instrumentalities).

TRUSTEES AND OFFICERS

The Trust's Trustees, in addition to supervising the actions of the
Trust's Administrator and Distributor, as set forth below, decide upon matters
of general policy with respect to the Trust. The Portfolio's Trustees, in
addition to supervising the actions of the Portfolio's Investment Adviser and
Administrator, as set forth below, decide upon matters of general policy with
respect to the Portfolio. The Trust's Trustees are not the same individuals as
the Portfolio's Trustees.

Because of the services rendered to the Portfolio by the Investment
Adviser and to the Trust and the Portfolio by their respective Administrators,
the Trust and the Portfolio require no employees, and their respective officers,
other than the Chairmen, receive no compensation from the Fund or the Portfolio.

By virtue of the responsibilities assumed by Brown Brothers Harriman &
Co. under the Investment Advisory Agreement with the Portfolio and the
Administration Agreement with the Fund, and by Brown Brothers Harriman Trust
Company under the Administration Agreement with the Portfolio (see "Investment
Adviser" and "Administrators"), neither the Trust nor the Portfolio requires
employees other than its officers, and none of its officers devote full time to
the affairs of the Trust or the Portfolio, as the case may be, or, other than
the Chairmen, receive any compensation from the Fund or the Portfolio.

As of September 30, 1999, the Trustees and officers of the Trust and
the Portfolio as a group owned less than 1% of the outstanding shares of the
Trust and less than 1% of the aggregate beneficial interests in the Portfolio.
At the close of business on that date no person, to the knowledge of management,
owned beneficially more than 5% of the outstanding shares of the Fund nor more
than 5% of the aggregate beneficial interests in the Portfolio. Partners of
Brown Brothers Harriman & Co. and their immediate families owned 39,905,727
(3.48%) shares of the Fund. Brown Brothers Harriman & Co. and its affiliates
separately were able to direct the disposition of an additional 481,089,353
(41.95%) shares of the Fund, as to which shares Brown Brothers Harriman & Co.
disclaims beneficial ownership.

INVESTMENT ADVISER

Under its Investment Advisory Agreement with the Portfolio, subject to
the general supervision of the Portfolio's Trustees and in conformance with the
stated policies of the Portfolio, Brown Brothers Harriman & Co. provides
investment advice and portfolio management services to the Portfolio. In this
regard, it is the responsibility of Brown Brothers Harriman & Co. to make the
day-to-day investment decisions for the Portfolio, to place the purchase and
sale orders for portfolio transactions and to manage, generally, the Portfolio's
investments.

The Investment Advisory Agreement between Brown Brothers Harriman & Co.
and the Portfolio is dated December 15, 1993, amended and restated July 1, 2000,
and remains in effect for two years from such date and thereafter, but only as
long as the agreement is specifically approved at least annually (i) by a vote
of the holders of a "majority of the outstanding voting securities" (as defined
in the 1940 Act) of the Portfolio, or by the Portfolio's Trustees, and (ii) by a
vote of a majority of the Trustees of the Portfolio who are not parties to the
Investment Advisory Agreement or "interested persons" (as defined in the 1940
Act) of the Portfolio ("Independent Trustees"), cast in person at a meeting
called for the purpose of voting on such approval. The Investment Advisory
Agreement was most recently approved by the Independent Trustees on May 9, 2000.
The Investment Advisory Agreement terminates automatically if assigned and is
terminable at any time without penalty by a vote of a majority of the Trustees
of the Portfolio or by a vote of the holders of a "majority of the outstanding
voting securities" (as defined in the 1940 Act) of the Portfolio on 60 days'
written notice to Brown Brothers Harriman & Co. and by Brown Brothers Harriman &
Co. on 90 days' written notice to the Portfolio (see "Additional Information").

With respect to the Portfolio, the investment advisory fee paid to the
Investment Adviser is calculated daily and paid monthly at an annual rate equal
to 0.10% of the Portfolio's average daily net assets. Prior to July 1, 2000, the
investment advisory fee paid to the Investment Adviser was calculated daily and
paid monthly at an annual rate equal to 0.15% of the Portfolio's average daily
net assets. For the fiscal years ended June 30, 1999, 1998 and 1997, the
Portfolio incurred $1,593,123, $1,466,761 and $1,274,559, respectively, for
advisory services.

The investment advisory services of Brown Brothers Harriman & Co. to the
Portfolio are not exclusive under the terms of the Investment Advisory
Agreement. Brown Brothers Harriman & Co. is free to and does render investment
advisory services to others, including other registered investment companies.

Pursuant to a license agreement between the Trust and Brown Brothers
Harriman & Co. dated August 24, 1989, as amended as of December 15, 1993, the
Trust may continue to use in its name "59 Wall Street", the current and historic
address of Brown Brothers Harriman & Co. The agreement may be terminated by
Brown Brothers Harriman & Co. at any time upon written notice to the Trust upon
the expiration or earlier termination of any investment advisory agreement
between the Trust or any investment company in which a series of the Trust
invests all of its assets and Brown Brothers Harriman & Co. Termination of the
agreement would require the Trust to change its name and the name of the Fund to
eliminate all reference to "59 Wall Street".

Pursuant to license agreements between Brown Brothers Harriman & Co. and
each of 59 Wall Street Administrators and 59 Wall Street Distributors (each a
"Licensee"), dated June 22, 1993 and June 8, 1990, respectively, each Licensee
may continue to use in its name "59 Wall Street", the current and historic
address of Brown Brothers Harriman & Co., only if Brown Brothers Harriman & Co.
does not terminate the respective license agreement, which would require the
Licensee to change its name to eliminate all reference to "59 Wall Street".

Pursuant to a license agreement between the Portfolio and Brown
Brothers Harriman & Co. dated May 9, 2000, the Portfolio may continue to use in
its name BBH. The agreement may be terminated by Brown Brothers Harriman & Co.
at any time upon written notice to the Portfolio upon the expiration or earlier
termination of any investment advisory agreement between the Portfolio and Brown
Brothers Harriman & Co. Termination of the agreement would require the Portfolio
to change its name to eliminate all reference to BBH.

Brown Brothers Harriman & Co. acts as Administrator of the Trust and
Brown Brothers Harriman Trust Company, LLC acts as Administrator of the
Portfolio. Brown Brothers Harriman Trust Company, LLC is a wholly-owned

In its capacity as Administrator of the Trust, Brown Brothers Harriman &
Co. administers all aspects of the Trust's operations subject to the supervision
of the Trust's Trustees except as set forth below under "Distributor". In

INDEPENDENT AUDITORS

Deloitte & Touche LLP, Boston, Massachusetts are the independent auditors

NET ASSET VALUE

The net asset value of each of the Fund's shares is determined each day
the New York Stock Exchange is open for regular trading and New York banks are
open for business. (As of the date of this Statement of Additional Information,
such Exchange and banks are so open every weekday except for the following
holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day,
Thanksgiving Day and Christmas.) This determination of net asset value of each
share of the Fund is made once during each such day as of the close of regular
trading on such Exchange by subtracting from the value of the Fund's total
assets (i.e., the value of its investment in the Portfolio and other assets) the
amount of its liabilities, including expenses payable or accrued, and dividing
the difference by the number of shares of the Fund outstanding at the time the
determination is made. It is anticipated that the net asset value of each share
of the Fund will remain constant at $1.00 and, although no assurance can be
given that it will be able to do so on a continuing basis, the Trust and the
Portfolio employ specific investment policies and procedures to accomplish this
result.

The value of the Portfolio's net assets (i.e., the value of its
securities and other assets less its liabilities, including expenses payable or
accrued) is determined at the same time and on the same days as the net asset
value per share of the Fund is determined. The determination of the value of the
Fund's investment in the Portfolio is made by subtracting from the value of the
total assets of the Portfolio the amount of the Portfolio's liabilities and
multiplying the difference by the percentage, effective for that day, which
represents the Fund's share of the aggregate beneficial interests in the
Portfolio. The value of the Fund's investment in the Portfolio is determined
once daily at 4:00 P.M., New York time on each day the New York Stock Exchange
is open for regular trading and New York banks are open for business.

The Portfolio's assets are valued by using the amortized cost method of
valuation. This method involves valuing a security at its cost at the time of
purchase and thereafter assuming a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of the instrument. The market value of the securities held by
the Portfolio fluctuates on the basis of the creditworthiness of the issuers of
such securities and on the levels of interest rates generally. While the
amortized cost method provides certainty in valuation, it may result in periods
when the value so determined is higher or lower than the price the Portfolio
would receive if the security were sold.

Pursuant to a rule of the Securities and Exchange Commission, an
investment company may use the amortized cost method of valuation subject to
certain conditions and the determination that such method is in the best
interests of the Fund's shareholders and the Portfolio's other investors. The
use of amortized cost valuations is subject to the following conditions: (i) as
a particular responsibility within the overall duty of care owed to the
Portfolio's investors, the Trustees of the Portfolio have established procedures
reasonably designed, taking into account current market conditions and the
investment objective of its investors, to stabilize the net asset value as
computed; (ii) the procedures include periodic review by the Trustees of the
Portfolio, as they deem appropriate and at such intervals as are reasonable in
light of current market conditions, of the relationship between the value of the
Portfolio's net assets using amortized cost and the value of the Portfolio's net
assets based upon available indications of market value with respect to such
portfolio securities; (iii) the Trustees of the Portfolio will consider what
steps, if any, should be taken if a difference of more than 1/2 of 1% occurs
between the two methods of valuation; and (iv) the Trustees of the Portfolio
will take such steps as they consider appropriate, such as shortening the
average portfolio maturity, realizing gains or losses, establishing the value of
the Portfolio's net assets by using available market quotations, or reducing the
value of interests in the Portfolio, to minimize any material dilution or other
unfair results which might arise from differences between the two methods of
valuation.

Such conditions also generally require that: (i) investments for the
Portfolio be limited to instruments which the Trustees of the Portfolio
determine present minimal credit risks and which are of high quality as
determined by any nationally recognized statistical rating organization that is
not an affiliated person of the issuer of, or any issuer, guarantor or provider
of credit support for, the instrument, or, in the case of any instrument that is
not so rated, is of comparable quality as determined by the Investment Adviser
under the general supervision of the Trustees of the Portfolio; (ii) a
dollar-weighted average portfolio maturity of not more than 90 days be
maintained and no instrument is purchased with a remaining maturity of more than
397 days; (iii) the Portfolio's available cash will be invested in such a manner
as to reduce such maturity to 90 days or less as soon as is reasonably
practicable, if the disposition of a portfolio security results in a
dollar-weighted average portfolio maturity of more than 90 days; and (iv) no
more than 5% of the Portfolio's total assets may be invested in the securities
of any one issuer (other than U.S. Government securities).

It is expected that the Fund will have a positive net income at the
time of each determination thereof. If for any reason the Fund's net income is a
negative amount, which could occur, for instance, upon default by an issuer of a
portfolio security, the Fund would first offset the negative amount with respect
to each shareholder account from the dividends declared during the month with
respect to those accounts. If and to the extent that negative net income exceeds
declared dividends at the end of the month, the Fund would reduce the number of
outstanding Fund shares by treating each shareholder as having contributed to
the capital of the Fund that number of full and fractional shares in his or her
account which represents his or her share of the amount of such excess. Each
shareholder would be deemed to have agreed to such contribution in these
circumstances by his or her investment in the Fund.

COMPUTATION OF PERFORMANCE

The current and effective yields of the Fund may be used from time to
time in shareholder reports or other communications to shareholders or
prospective investors. Seven-day current yield is computed by dividing the net
change in account value (exclusive of capital changes) of a hypothetical
pre-existing account having a balance of one share at the beginning of a
seven-day calendar period by the value of that account at the beginning of that
period, and multiplying the return over the seven-day period by 365/7. For
purposes of the calculation, net change in account value reflects the value of
additional shares purchased with dividends from the original share and dividends
declared on both the original share and any such additional shares, but does not
reflect realized gains or losses or unrealized appreciation or depreciation. The
Fund's current yield for the seven-day calendar period ended June 30, 1999 was
4.51%. In addition, the Trust may use an effective annualized yield quotation
for the Fund computed on a compounded basis by adding 1 to the base period
return (calculated as described above), raising the sum to a power equal to
365/7, and subtracting 1 from the result. Based upon this latter method, the
Fund's effective annualized yield for the seven-day calendar period ended June
30, 1999 was 4.41%.

The yield should not be considered a representation of the yield of the
Fund in the future since the yield is not fixed. Actual yields will depend on
the type, quality and maturities of the investments held for the Portfolio,
changes in interest rates on investments, and the Fund's expenses during the
period.

Yield information may be useful for reviewing the performance of the
Fund and for providing a basis for comparison with other investment
alternatives. However, unlike bank deposits or other investments which pay a
fixed yield for a stated period of time, the Fund's yield does fluctuate, and
this should be considered when reviewing performance or making comparisons.

The Fund's "yield" and "effective yield" may be used from time to time in
shareholder reports or other communications to shareholders or prospective
investors. Both yield figures are based on historical earnings and are not
intended to indicate future performance. Performance information may include the
Fund's investment results and/or comparisons of its investment results to
various unmanaged indexes (such as 1-month LIBOR) and to investments for which
reliable performance data is available. Performance information may also include
comparisons to averages, performance rankings or other information prepared by
recognized mutual fund statistical services. To the extent that unmanaged
indexes are so included, the same indexes will be used on a consistent basis.
The Fund's investment results as used in such communications are calculated in
the manner set forth below.

The "yield" of the Fund refers to the income generated by an investment
in the Fund over a seven-day period (which period will be stated). This income
is then "annualized". That is, the amount of income generated by the investment
during that week is assumed to be generated each week over a 52-week period and
is shown as a percentage of the investment. The "effective yield" is calculated
similarly but, when annualized, the income earned by an investment in the Fund
is assumed to be reinvested. The "effective yield" is slightly higher than the
"yield" because of the compounding effect of this assumed reinvestment.

PURCHASES AND REDEMPTIONS

A confirmation of each purchase and redemption transaction is issued
on execution of that transaction.

A shareholder's right to receive payment with respect to any redemption
may be suspended or the payment of the redemption proceeds postponed: (i) during
periods when the New York Stock Exchange is closed for other than weekends and
holidays or when regular trading on such Exchange is restricted as determined by
the Securities and Exchange Commission by rule or regulation, (ii) during
periods in which an emergency exists which causes disposal of, or evaluation of
the net asset value of, portfolio securities to be unreasonable or
impracticable, or (iii) for such other periods as the Securities and Exchange
Commission may permit.

An investor should be aware that redemptions from the Fund may not be
processed if a completed account application with a certified taxpayer
identification number has not been received.

In the event a shareholder redeems all shares held in the Fund at any
time during the month, all accrued but unpaid dividends are included in the
proceeds of the redemption and future purchases of shares of the Fund by such
shareholder would be subject to the Fund's minimum initial purchase
requirements.

The Trust reserves the right to discontinue, alter or limit the
automatic reinvestment privilege at any time, but will provide shareholders
prior written notice of any such discontinuance, alteration or limitation.

FEDERAL TAXES

Dividends of net income and net short-term capital gains, if any, are
taxable to shareholders of the Fund as ordinary income, whether such dividends
are paid in cash or reinvested in additional shares. These distributions are not
eligible for the dividends-received deduction allowed to corporate shareholders.

Each year, the Trust intends to continue to qualify the Fund and elect
that the Fund be treated as a separate "regulated investment company" under
Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code").
Under Subchapter M of the Code the Fund is not subject to federal income taxes
on amounts distributed to shareholders. A 4% non-deductible excise tax is
imposed on the Fund to the extent that certain distribution requirements for the
Fund for each calendar year are not met. The Trust intends to continue to meet
such requirements. The Portfolio is also not required to pay any federal income
or excise taxes.

Qualification as a regulated investment company under the Code
requires, among other things, that (a) at least 90% of the Fund's annual gross
income, without offset for losses from the sale or other disposition of
securities, be derived from interest, payments with respect to securities loans,
dividends and gains from the sale or other disposition of securities or other
income derived with respect to its business of investing in such securities; (b)
less than 30% of the Fund's annual gross income be derived from gains (without
offset for losses) from the sale or other disposition of securities held for
less than three months; and (c) the holdings of the Fund be diversified so that,
at the end of each quarter of its fiscal year, (i) at least 50% of the market
value of the Fund's assets be represented by cash, U.S. Government securities
and other securities limited in respect of any one issuer to an amount not
greater than 5% of the Fund's assets and 10% of the outstanding voting
securities of such issuer, and (ii) not more than 25% of the value of the Fund's
assets be invested in the securities of any one issuer (other than U.S.
Government securities and securities of other investment companies). In
addition, in order not to be subject to federal income tax, at least 90% of the
Fund's net investment income and net short-term capital gains earned in each
year must be distributed to the Fund's shareholders.

To maintain a constant $1.00 per share net asset value, the Trustees
may direct that the number of outstanding shares be reduced pro rata. If this
adjustment is made, it will reflect the lower market value of portfolio
securities and not realized losses.

Other Taxes. The treatment of the Fund and its shareholders in those
states which have income tax laws might differ from treatment under the federal
income tax laws. Distributions to shareholders may be subject to additional
state and local taxes. Shareholders are urged to consult their tax advisors
regarding any state or local taxes.

Other Information. Annual notification as to the tax status of capital
gains distributions, if any, is provided to shareholders shortly after June 30,
the end of the Fund's fiscal year. Additional tax information is mailed to
shareholders in January. Under U.S. Treasury regulations, the Trust and each
Eligible Institution are required to withhold and remit to the U.S. Treasury a
portion (31%) of dividends and capital gains distributions on the accounts of
those shareholders who fail to provide a correct taxpayer identification number
(Social Security Number for individuals) or to make required certifications, or
who have been notified by the Internal Revenue Service that they are subject to
such withholdings. Prospective investors should submit an IRS Form W-9 to avoid
such withholding.

This tax discussion is based on the tax laws and regulations in effect on
the date of this Prospectus, however such laws and regulations are subject to
change. Shareholders and prospective investors are urged to consult their tax
advisors regarding specific questions relevant to their particular
circumstances.

DESCRIPTION OF SHARES

The Trust is an open-end management investment company organized on
June 7, 1983, as an unincorporated business trust under the laws of the
Commonwealth of Massachusetts. Its offices are located at 21 Milk Street,
Boston, Massachusetts 02109; its telephone number is (617) 423-0800. The Trust's
Declaration of Trust permits the Trust's Board of Trustees to issue an unlimited
number of full and fractional shares of beneficial interest and to divide or
combine the shares into a greater or lesser number of shares without thereby
changing the proportionate beneficial interests in the Trust. Each Fund share
represents an equal proportionate interest in the Fund with each other share.
Upon liquidation or dissolution of the Fund, the Fund's shareholders are
entitled to share pro rata in the Fund's net assets available for distribution
to its shareholders. Shares of each series participate equally in the earnings,
dividends and assets of the particular series. Shares of each series are
entitled to vote separately to approve advisory agreements or changes in
investment policy, but shares of all series vote together in the election or
selection of the Trust's Trustees, principal underwriters and auditors for the
Trust. Upon liquidation or dissolution of the Trust, the shareholders of each
series are entitled to share pro rata in the net assets of their respective
series available for distribution to shareholders. The Trust reserves the right
to create and issue additional series of shares. The Trust currently consists of
four series.

Each share of the Fund represents an equal proportional interest in the
Fund with each other share. Upon liquidation of the Fund, shareholders are
entitled to share pro rata in the net assets of the Fund available for
distribution to shareholders.

Shareholders are entitled to one vote for each share held on matters on
which they are entitled to vote. Shareholders in the Trust do not have
cumulative voting rights, and shareholders owning more than 50% of the
outstanding shares of the Trust may elect all of the Trustees of the Trust if
they choose to do so and in such event the other shareholders in the Trust would
not be able to elect any Trustee of the Trust. The Trust is not required and has
no current intention to hold meetings of shareholders annually but the Trust
will hold special meetings of shareholders when in the judgment of the Trust's
Trustees it is necessary or desirable to submit matters for a shareholder vote.
Shareholders have under certain circumstances (e.g., upon application and
submission of certain specified documents to the Trustees of the Trust by a
specified number of shareholders) the right to communicate with other
shareholders in connection with requesting a meeting of shareholders for the
purpose of removing one or more Trustees of the Trust. Shareholders also have
the right to remove one or more Trustees of the Trust without a meeting by a
declaration in writing by a specified number of shareholders. No material
amendment may be made to the Trust's Declaration of Trust without the
affirmative vote of the holders of a majority of its outstanding shares. Shares
have no preference, pre-emptive, conversion or similar rights. Shares, when
issued, are fully paid and non-assessable, except as set forth below. The Trust
may enter into a merger or consolidation, or sell all or substantially all of
its assets, if approved by the vote of the holders of two-thirds of its
outstanding shares, except that if the Trustees of the Trust recommend such sale
of assets, the approval by vote of the holders of a majority of the Trust's
outstanding shares will be sufficient. The Trust may also be terminated upon
liquidation and distribution of its assets, if approved by the vote of the
holders of two-thirds of its outstanding shares.

Stock certificates are not issued by the Trust.

The By-Laws of the Trust provide that the presence in person or by proxy
of the holders of record of one half of the shares of the Fund outstanding and
entitled to vote thereat shall constitute a quorum at all meetings of Fund
shareholders, except as otherwise required by applicable law. The By-Laws
further provide that all questions shall be decided by a majority of the votes
cast at any such meeting at which a quorum is present, except as otherwise
required by applicable law.

The Trustees of the Trust themselves have the power to alter the number
and the terms of office of the Trustees of the Trust, to lengthen their own
terms, or to make their terms of unlimited duration subject to certain removal
procedures, and to appoint their own successors; provided that at least
two-thirds of the Trustees of the Trust have been elected by the shareholders.

The Trust's Declaration of Trust provides that, at any meeting of
shareholders of the Fund, each Eligible Institution may vote any shares as to
which that Eligible Institution is the agent of record and which are otherwise
not represented in person or by proxy at the meeting, proportionately in
accordance with the votes cast by holders of all shares otherwise represented at
the meeting in person or by proxy as to which that Eligible Institution is the
agent of record. Any shares so voted by an Eligible Institution are deemed
represented at the meeting for purposes of quorum requirements.

The Portfolio, in which all of the assets of the Fund are invested, is
organized as a trust under the law of the State of New York. The Portfolio's
Declaration of Trust provides that the Fund and other entities investing in the
Portfolio (e.g., other investment companies, insurance company separate accounts
and common and commingled trust funds) are each liable for all obligations of
the Portfolio. However, the risk of the Fund incurring financial loss on account
of such liability is limited to circumstances in which both inadequate insurance
existed and the Portfolio itself was unable to meet its obligations.
Accordingly, the Trustees of the Trust believe that neither the Fund nor its
shareholders will be adversely affected by reason of the investment of all of
the assets of the Fund in the Portfolio.

Each investor in the Portfolio, including the Fund, may add to or reduce
its investment in the Portfolio on each day the New York Stock Exchange is open
for regular trading and New York banks are open for business. At 4:00 P.M., New
York time on each such business day, the value of each investor's beneficial
interest in the Portfolio is determined by multiplying the net asset value of
the Portfolio by the percentage, effective for that day, which represents that
investor's share of the aggregate beneficial interests in the Portfolio. Any
additions or withdrawals, which are to be effected on that day, are then
effected. The investor's percentage of the aggregate beneficial interests in the
Portfolio is then recomputed as the percentage equal to the fraction (i) the
numerator of which is the value of such investor's investment in the Portfolio
as of 4:00 P.M., New York time on such day plus or minus, as the case may be,
the amount of any additions to or withdrawals from the investor's investment in
the Portfolio effected on such day, and (ii) the denominator of which is the
aggregate net asset value of the Portfolio as of 4:00 P.M., New York time on
such day plus or minus, as the case may be, the amount of the net additions to
or withdrawals from the aggregate investments in the Portfolio by all investors
in the Portfolio. The percentage so determined is then applied to determine the
value of the investor's interest in the Portfolio as of 4:00 P.M., New York time
on the following business day of the Portfolio.

The Trust is an entity of the type commonly known as a "Massachusetts
business trust". Under Massachusetts law, shareholders of such a business trust
may, under certain circumstances, be held personally liable as partners for its
obligations and liabilities. However, the Declaration of Trust contains an
express disclaimer of shareholder liability for acts or obligations of the Trust
and provides for indemnification and reimbursement of expenses out of Trust
property for any shareholder held personally liable for the obligations of the
Trust. The Declaration of Trust also provides that the Trust shall maintain
appropriate insurance (for example, fidelity bonding and errors and omissions
insurance) for the protection of the Trust, its shareholders, Trustees,
officers, employees and agents covering possible tort and other liabilities.
Thus, the risk of a shareholder's incurring financial loss because of
shareholder liability is limited to circumstances in which both inadequate
insurance existed and the Trust itself was unable to meet its obligations.

Whenever the Trust is requested to vote on a matter pertaining to the
Portfolio, the Trust will vote its shares without a meeting of shareholders of
the Fund if the proposal is one, if which made with respect to the Fund, would
not require the vote of shareholders of the Fund as long as such action is
permissible under applicable statutory and regulatory requirements. For all
other matters requiring a vote, the Trust will hold a meeting of shareholders of
the Fund and, at the meeting of investors in the Portfolio, the Trust will cast
all of its votes in the same proportion as the votes of the Fund's shareholders
even if all Fund shareholders did not vote. Even if the Trust votes all its
shares at the Portfolio meeting, other investors with a greater pro rata
ownership in the Portfolio could have effective voting control of the operations
of the Portfolio.

The Declaration of Trust further provides that obligations of the Trust
are not binding upon the Trust's Trustees individually but only upon the
property of the Trust and that the Trust's Trustees are not liable for any
action or failure to act, but nothing in the Declaration of Trust protects a
Trust's Trustee against any liability to which he would otherwise be subject by
reason of wilful misfeasance, bad faith, gross negligence, or reckless disregard
of the duties involved in the conduct of his office.

Interests in the Portfolio have no preference, preemptive, conversion
or similar rights, and are fully paid and non-assessable. The Portfolio is not
required to hold annual meetings of investors, but will hold special meetings of
investors when, in the judgment of its trustees, it is necessary or desirable to
submit matters for an investor vote. Each investor is entitled to a vote in
proportion to the share of its investment in the Portfolio.

PORTFOLIO BROKERAGE TRANSACTIONS

Brown Brothers Harriman & Co., as Investment Adviser for the Portfolio,
places orders for all purchases and sales of portfolio securities, enters into
repurchase and reverse repurchase agreements and executes loans of portfolio
securities. Fixed-income securities are generally traded at a net price with
dealers acting as principal for their own account without a stated commission.
The price of the security usually includes a profit to the dealer. In
underwritten offerings, securities are purchased at a fixed price which includes
an amount of compensation to the underwriter, generally referred to as the
underwriter's concession or discount. On occasion, certain money market
instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid. From time to time certificates of deposit may
be purchased through intermediaries who may charge a commission for their
services.

On those occasions when Brown Brothers Harriman & Co. deems the
purchase or sale of a security to be in the best interests of the Portfolio as
well as other customers, Brown Brothers Harriman & Co., to the extent permitted
by applicable laws and regulations, may, but is not obligated to, aggregate the
securities to be sold or purchased with those to be sold or purchased for other
customers in order to obtain best execution, including lower brokerage
commissions, if appropriate. In such event, allocation of the securities so
purchased or sold as well as any expenses incurred in the transaction are made
by Brown Brothers Harriman & Co. in the manner it considers to be most equitable
and consistent with its fiduciary obligations to its customers, including the
Portfolio. In some instances, this procedure might adversely affect the
Portfolio.

Although the Portfolio generally holds investments until maturity and
does not seek profits through short-term trading, it may dispose of any
portfolio security prior to its maturity if it believes such disposition
advisable.

Money market securities are generally traded on a net basis and do not
normally involve either brokerage commissions or transfer taxes. Where possible
transactions on behalf of the Portfolio are entered directly with the issuer or
from an underwriter or market maker for the securities involved. Purchases from
underwriters of securities may include a commission or concession paid by the
issuer to the underwriter, and purchases from dealers serving as market makers
may include a spread between the bid and asked price. The policy of the
Portfolio regarding purchases and sales of securities is that primary
consideration will be given to obtaining the most favorable prices and efficient
executions of transactions. In seeking to implement the Portfolio's policies,
the Investment Adviser effects transactions with those brokers and dealers who
the Investment Adviser believes provide the most favorable prices and are
capable of providing efficient executions. If the Investment Adviser believes
such prices and executions are obtainable from more than one broker or dealer,
it may give consideration to placing portfolio transactions with those brokers
and dealers who also furnish research and other services to the Portfolio and or
the Investment Adviser. Such services may include, but are not limited to, any
one or more of the following: information as to the availability of securities
for purchase or sale; statistical or factual information or opinions pertaining
to investment; and appraisals or evaluations of portfolio securities.

BOND, NOTE AND COMMERCIAL PAPER RATINGS

There is no additional percentage limitation with respect to investments
in negotiable certificates of deposit, fixed time deposits and bankers'
acceptances of U.S. branches of U.S. banks and U.S. branches of non-U.S. banks
that are subject to the same regulation as U.S. banks. Since the Portfolio may
contain U.S. dollar-denominated certificates of deposit, fixed time deposits and
bankers' acceptances that are issued by non-U.S. banks and their non-U.S.
branches, the Portfolio may be subject to additional investment risks with
respect to those securities that are different in some respects from obligations
of U.S. issuers, such as currency exchange control regulations, the possibility
of expropriation, seizure or nationalization of non-U.S. deposits, less
liquidity and more volatility in non-U.S. securities markets and the impact of
political, social or diplomatic developments or the adoption of other foreign
government restrictions which might adversely affect the payment of principal
and interest on securities held by the Portfolio. If it should become necessary,
greater difficulties might be encountered in invoking legal processes abroad
than would be the case in the United States. Issuers of non-U.S. bank
obligations may be subject to less stringent or different regulations than are
U.S. bank issuers, there may be less publicly available information about a
non-U.S. issuer, and non-U.S. issuers generally are not subject to uniform
accounting and financial reporting standards, practices and requirements
comparable to those applicable to U.S. issuers. Income earned or received by the
Portfolio from sources within countries other than the United States may be
reduced by withholding and other taxes imposed by such countries. Tax
conventions between certain countries and the United States, however, may reduce
or eliminate such taxes. All such taxes paid by the Portfolio would reduce its
net income available for distribution to investors (i.e., the Fund and other
investors in the Portfolio); however, the Investment Adviser would consider
available yields, net of any required taxes, in selecting securities of non-U.S.
issuers. While early withdrawals are not contemplated, fixed time deposits are
not readily marketable and may be subject to early withdrawal penalties, which
may vary. Assets of the Portfolio are not invested in obligations of Brown
Brothers Harriman & Co., or the Distributor, or in the obligations of the
affiliates of any such organization. Assets of the Portfolio are also not
invested in fixed time deposits with a maturity of over seven calendar days, or
in fixed time deposits with a maturity of from two business days to seven
calendar days if more than 10% of the Portfolio's net assets would be invested
in such deposits.

Bond Ratings

Moody's Investors Service, Inc. ("Moody's")

Aaa - Bonds rated Aaa are judged to be of the "best quality". Issues
rated Aaa may be further modified by the numbers 1, 2 or 3 (3 being the highest)
to show relative strength within the rating category.

Standard & Poor's Corporation ("S&P")

AAA - The AAA rating is the highest rating assigned to debt obligations
and indicates an extremely strong capacity to pay principal and interest.

Note and Variable Rate Investment Ratings

Moody's - MIG-1. Notes rated MIG-1 are judged to be of the best
quality, enjoying strong protection from established cash flow of funds for
their services or from established and broad-based access to the market for
refinancing or both.

S&P - SP-1. SP-1 denotes a very strong or strong capacity to pay
principal and interest. Issues determined to possess overwhelming safety
characteristics are given a plus (+) designation (SP-1+).

Corporate Commercial Paper Ratings

Moody's - Commercial Paper ratings are opinions of the ability of
issuers to repay punctually promissory obligations not having an original
maturity in excess of nine months. Prime-1 indicates highest quality repayment
capacity of rated issue.

S&P - Commercial Paper ratings are a current assessment of the
likelihood of timely payment of debts having an original maturity of no more
than 365 days. Issues rated A-1 have the greatest capacity for timely payment.
Issues rated "A-1+" are those with an "overwhelming degree of credit
protection."

Other Considerations

Among the factors considered by Moody's in assigning bond, note and
commercial paper ratings are the following: (i) evaluation of the management of
the issuer; (ii) economic evaluation of the issuer's industry or industries and
an appraisal of speculative-type risks which may be inherent in certain areas;
(iii) evaluation of the issuer's products in relation to competition and
customer acceptance; (iv) liquidity; (v) amount and quality of long-term debt;
(vi) trend of earnings over a period of 10 years; (vii) financial strength of a
parent company and the relationships which exist with the issuer; and (viii)
recognition by management of obligations which may be present or may arise as a
result of public interest questions and preparations to meet such obligations.

Among the factors considered by S&P in assigning bond, note and
commercial paper ratings are the following: (i) trend of earnings and cash flow
with allowances made for unusual circumstances, (ii) stability of the issuer's
industry, (iii) the issuer's relative strength and position within the industry
and (iv) the reliability and quality of management.

ADDITIONAL INFORMATION

As used in this Statement of Additional Information and the Prospectus,
the term "majority of the outstanding voting securities" (as defined in the 1940
Act) currently means the vote of (i) 67% or more of the outstanding voting
securities present at a meeting, if the holders of more than 50% of the
outstanding voting securities are present in person or represented by proxy; or
(ii) more than 50% of the outstanding voting securities, whichever is less.

Fund shareholders receive semi-annual reports containing unaudited
financial statements and annual reports containing financial statements audited
by independent auditors.

Other mutual funds or institutional investors may invest in the Portfolio
on the same terms and conditions as the Fund. However, these other investors may
have different operating expenses which may generate different aggregate
performance results. Information concerning other investors in the Portfolio is
available from Brown Brothers Harriman & Co.

The Trust may withdraw the Fund's investment in the Portfolio as a result
of certain changes in the Portfolio's investment objective, policies or
restrictions or if the Board of Trustees of the Trust determines that it is
otherwise in the best interests of the Fund to do so. Upon any such withdrawal,
the Board of Trustees of the Trust would consider what action might be taken,
including the investment of all of the assets of the Fund in another pooled
investment entity or the retaining of an investment adviser to manage the Fund's
assets in accordance with the investment policies described above with respect
to the Portfolio. In the event the Trustees of the Trust were unable to
accomplish either, the Trustees will determine the best course of action.

Statement of Additional Information and the Prospectus do not contain all the

ITEM 25. INDEMNIFICATION.

As permitted by Section 17(h) of the Investment Company Act of 1940, as
amended (the "1940 Act"), and pursuant to Article VII of the Registrant's
By-Laws, officers, Trustees, employees and agents of the Registrant may be
indemnified against certain liabilities in connection with the Registrant. As
permitted by Section 17(i) of the 1940 Act, pursuant to Section 5 of the
Distribution Agreement, 59 Wall Street Distributors, Inc., as Distributor of
shares of each series of the Registrant, may be indemnified against certain
liabilities which it may incur. Such Article VII of the By-Laws and Section 5 of
the Distribution Agreement are hereby incorporated by reference in their
entirety.

Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Act"), may be permitted to Trustees, officers and
controlling persons of the Registrant and the principal underwriter pursuant to
the foregoing provisions, or otherwise, the Registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a Trustee,
officer of controlling person of the Registrant or the principal underwriter in
connection with the successful defense of any action, suit or proceeding) is
asserted against the Registrant by such Trustee, officer or controlling person
or the principal underwriter in connection with the securities being registered,
the Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question of whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

ITEM 26. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER.

The investment adviser of the Registrant's Money Market Fund, Brown
Brothers Harriman & Co. ("BBH & Co."), is a New York limited partnership. BBH &
Co. conducts a general banking business and is a member of the New York Stock
