EXPENSE TABLE
================================================================================

     The following table provides (i) a summary of estimated  expenses  relating
to purchases and sales of shares of the Fund, and the aggregate annual operating
expenses of the Fund and the Portfolio, as a percentage of average net assets of
the Fund,  and (ii) an example  illustrating  the dollar cost of such  estimated
expenses on a $1,000  investment in the Fund.  The Trustees of the Trust believe
that the aggregate per share expenses of the Fund and the Portfolio will be less
than or  approximately  equal to the expenses  which the Fund would incur if the
Trust  retained the services of an investment  adviser on behalf of the Fund and
the assets of the Fund were invested  directly in the type of  securities  being
held by the Portfolio.

      A shareholder of the Fund would pay the following expenses on a
        $1,000 investment, assuming (1) 5% annual return, and (2)
        redemption at the end of each time period...................       $ 6       $18        $31        $69
                                                                           ---       ---        ---        ---
</TABLE>

     The Example  should not be  considered a  representation  of past or future
expenses. Actual expenses may be greater or less than those shown. In connection
with the  Example,  please  note that $1,000 is  currently  less than the Fund's
minimum purchase  requirement.  The purpose of this table is to assist investors
in  understanding  the various costs and expenses that  shareholders of the Fund
bear directly or indirectly.

   
   Under an agreement dated July 1, 1993, 59 Wall Street Administrators pays the
Fund's expenses, other than fees paid to Brown Brothers Harriman & Co. under the
Trust's Administration  Agreement.  Had this expense reimbursement agreement not
been in place,  the total Fund  operating  expenses would have been 0.56% of the
Fund's average annual net assets and the shareholder  expenses  reflected in the
example  above would have been $6, $18, $31, and $70,  respectively.  After this
expense  reimbusement  agreement  terminates  on or before  June 30,  1997,  the
Trustees of the Trust  estimate  that, at the Fund's  current  asset level,  the
total Fund operating expenses will increase to approximately 0.56% of the fund's
average annual net assets. (See "Expense Reimbursement Agreement".)
    

   For  more  information  with  respect  to the  expenses  of the  Fund and the
Portfolio, see "Management of the Trust and the Portfolio" herein.

SPECIAL INFORMATION CONCERNING THE TWO-TIER FUND STRUCTURE
================================================================================

   The Trust seeks to achieve the investment  objective of the Fund, which is an
open-end  investment  company,  by  investing  all of the  Fund's  assets in the
Portfolio,  a separate  open-end  investment  company  with the same  investment
objective  as the Fund.  The use of the two-tier  structure  was approved by the
shareholders of the Fund on September 23, 1993. The two-tier  structure has been
developed  relatively  recently,  so shareholders should carefully consider this
investment approach. 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. (See the back cover
for the address and phone number.)

   
    The investment objective of the Fund may not be changed without the approval
of the  shareholders  of the Fund and the investment  objective of the Portfolio
may not be changed  without the  approval  of the  investors  in the  Portfolio.
Shareholders  of the Fund  shall  receive 30 days  prior  written  notice of any
change  in  the  investment  objective  of the  Fund  or  the  Portfolio.  For a
description  of the  investment  objective,  policies  and  restrictions  of the
Portfolio,  see  "Investment  Objective  and  Policies"  below  and  "Investment
Restrictions" on pages 6 & 7, respectively.
    

   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 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 below 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.

   As with  traditionally  structured  funds  which  have large  investors,  the
actions of such large investors may have a material affect on smaller investors.
For example, if a large investor withdraws from the Portfolio, a small remaining
fund may experience higher pro rata operating expenses,  thereby producing lower
returns.  Additionally,  the  Portfolio  may become less  diverse,  resulting in
increased portfolio risk.

   For  descriptions  of the  management  and  expenses  of the  Portfolio,  see
"Management  of the Trust and the  Portfolio" on page 10 and in the Statement of
Additional Information.

INVESTMENT OBJECTIVE AND POLICIES
================================================================================

   The investment  objective of the Fund and the Portfolio is to achieve as high
a level of current income as is consistent with the  preservation of capital and
the maintenance of liquidity.

   The  investment  objective  of the Fund and the  Portfolio  is a  fundamental
policy 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"  in this
Prospectus.)  However,  the investment policies as described below which are the
same for the Fund  and the  Portfolio  are not  fundamental  and may be  changed
without such approval.

   Investments for the Portfolio  mature or are deemed to mature within 397 days
from the date of purchase and the average  maturity of the  investments  held by
the Portfolio (on a dollar-weighted  basis) is 90 days or less.  Currently,  the
Portfolio's  investment  policy is to invest only in money  market  instruments,
including U.S. Government  securities and bank obligations (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.  (See Appendix for more information.) The
Portfolio  does not invest more than 5% of its total assets in  securities  of a
single issuer other than U.S.  Government  securities.  All of the assets of the
Portfolio are invested 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.  ("Moody's") and Standard & Poor's Corporation ("S&P"))
or,  if  unrated,  are of  comparable  quality  as  determined  by or under  the
direction of the Portfolio's Board of Trustees.

                                  Risk Factors

   Although the assets of the Portfolio are invested in high quality  short-term
securities, the Portfolio is subject to interest rate risk and credit risk which
causes  fluctuations  in  the  amount  of  income  accrued  on  the  Portfolio's
investments and therefore in the daily dividend paid by the Fund and, in extreme
cases,  could  cause the net asset  value per share of the Fund to deviate  from
$1.00 per share.  Interest rate risk refers to the price  fluctuation  of a debt
security  in  response to changes in  interest  rates.  In  general,  short-term
securities  have relatively  small  fluctuations in price in response to general
changes in interest  rates.  Credit risk refers to the likelihood that an issuer
will default on interest and  principal  payments.  High quality  securities  of
short maturities generally have relatively minimal credit risk.

                               Portfolio Brokerage

   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

                                       6
<PAGE>

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.  (See
"Portfolio Transactions" in the Statement of Additional Information.)

   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  for the  Portfolio  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.

                           Other Investment Techniques

   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.  These loans must be 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.  By lending  securities,  the  Portfolio's  income can be
increased by its continuing to receive  income on the loaned  securities as well
as by the opportunity to receive interest on the collateral. 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.

INVESTMENT RESTRICTIONS
================================================================================

   The  Statement of Additional  Information  for the Fund includes a listing of
the specific investment restrictions which govern the investment policies of the
Fund and the  Portfolio.  Certain of these  investment  restrictions  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" in
this Prospectus.)

   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 assets.

   As a non-fundamental policy, the Portfolio does not purchase more than 10% of
all outstanding debt obligations of any one issuer (other than securities issued
by the U.S. Government, its agencies or instrumentalities).  In addition, except
for the investment of all of the Fund's assets in an open-end investment company
with substantially the same investment  objective,  policies and restrictions as
the Fund, not more than 10% of the net assets of the Fund or the  Portfolio,  as
the case may be, may be  invested  in  securities  that are  subject to legal or
contractual restrictions on resale.

                                       7
<PAGE>

   

   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  company 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).

PURCHASE OF SHARES
================================================================================
       
   
   Shares of the Fund are offered on a continuous basis at their net asset value
without a sales charge.  The Trust  reserves the right to determine the purchase
orders for Fund shares that it will accept.  Shares of the Fund may be purchased
on any day the New York Stock Exchange is open for regular  trading and New York
banks  are open for  business  if the  Trust  receives  the  purchase  order and
acceptable payment for such order prior to 11:00 A.M., New York time.  Purchases
of Fund  shares  are  then  executed  at the net  asset  value  per  share  next
determined  on that same day.  Dividends are earned on the day that the purchase
is executed.

   An investor who has an account with an Eligible  Institution (see page 13) or
a Financial Intermediary (see page 13) may place purchase orders for Fund shares
with the Trust through that   Eligible  Institution  or Financial  Intermediary,
which holds such shares in its name on behalf of that  customer.  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.

   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 the Fund's Shareholder Servicing 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
to the  Trust's  account at State  Street  Bank and Trust  Company,  the Trust's
custodian  bank.  Such payment  must be in the form of either (a) an  inter-bank
wire transfer of "available  funds" prior to 11:00 A.M., New York time, in which
case a purchase order placed prior to 11:00 A.M., New York time is executed that
day, or (b) a cashier's  check drawn on a U.S.  bank or a check  certified  by a
U.S.  bank,  in which case a purchase  order is executed  after such a check has
been converted into "available funds", generally the next business day after the
check is received  for the Trust by State Street Bank and Trust  Company.  Brown
Brothers  Harriman  & Co.,  as  the  Fund's  Shareholder  Servicing  Agent,  has
established a minimum initial purchase requirement for the Fund of $10,000 and a
minimum subsequent  purchase  requirement for the Fund of $5,000.  These minimum
purchase requirements may be amended from time to time.

   Inquiries  regarding  the  manner in which  purchases  of Fund  shares may be
effected and other  matters  pertaining  to the Fund should be directed to Brown
Brothers Harriman & Co., the Fund's Shareholder Servicing Agent. (See back cover
for address and phone number.)
    

REDEMPTION OF SHARES
================================================================================
       
   
   A redemption  request must be received by the Trust prior to 11:00 A.M.,  New
York time on any day the New York Stock Exchange is open for regular trading and
New York banks are open for  business.  Such a redemption is executed at the net
asset value per share next determined on that same day. Proceeds of a redemption
are paid in "available  funds"  generally on the day the  redemption  request is
    

                                       8
<PAGE>

   
executed, and in any event within seven days. A shareholder continues to receive
each daily dividend  declared prior to the day on which a redemption  request is
executed.

   Shares held by an Eligible Institution or a Financial  Intermediary on behalf
of a shareholder must be redeemed through that Eligible Institution or Financial
Intermediary.  A transaction fee may be charged by an Eligible  Institution or a
Financial Intermediary on the redemption of Fund shares.

   Shares held directly in the name of a  shareholder  on the books of the Trust
may be redeemed by  submitting a  redemption  request in good order to the Trust
through the Fund's Shareholder  Servicing Agent. (See back cover for address and
phone number.)  Proceeds  resulting  from such  redemption are paid by the Trust
directly to the shareholder.
    

   A  shareholder  redeeming  shares should be aware that the net asset value of
the Fund's shares 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. See "Net Asset Value".

                            Redemptions By the Trust

   
   The  Fund's  Shareholder   Servicing  Agent  (see  page  12),  each  Eligible
Institution  and each  Financial  Intermediary  (see page 13) may  establish and
amend from time to time for their  respective  customers a minimum account size.
If the value of a  shareholder's  holdings  in the Fund falls  below that amount
because of a redemption of shares,  the  shareholder's  remaining  shares may be
redeemed.  If such remaining  shares are to be redeemed,  the  shareholder is so
notified and is allowed 60 days to make an  additional  investment to enable the
shareholder to meet the minimum  requirement before the redemption is processed.
Brown Brothers  Harriman & Co., as the Fund's  Shareholder  Servicing Agent, has
established a minimum account size of $10,000.
    

                         Further Redemption Information

   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.

   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.

   A  shareholder's  right to receive payment with respect to any redemption may
be suspended or the payment of the redemption proceeds postponed for up to seven
days and for such other  periods as the 1940 Act may  permit.  (See  "Additional
Information"  in the  Statement of  Additional  Information.)

   From  time to time,  the  Fund's  Shareholder  Servicing  Agent  enters  into

Shareholder  Servicing Agent as may be agreed upon from time to time between the
Shareholder Servicing Agent and such Financial Intermediary.
    

                              Eligible Institutions

   
   The Trust enters into eligible institution agreements with banks, brokers and
other financial  institutions pursuant to which that financial  institution,  as
agent for the Trust with respect to shareholders of and prospective investors in
the Fund who are  customers of that  financial  institution  among other things:
provides  necessary  personnel and facilities to establish and maintain  certain
shareholder  accounts and records  enabling it to hold, as agent, its customers'
shares in its name or its nominee name on the shareholder  records of the Trust;
assists in processing  purchase and  redemption  transactions;  arranges for the
wiring of funds; transmits and receives funds in connection with customer orders
to purchase or redeem shares of the Fund; provides periodic statements showing a
customer's  account  balance  and, to the extent  practicable,  integrates  such
information with information  concerning other customer  transactions  otherwise
effected with or through it;  furnishes,  either  separately or on an integrated
basis with other reports sent to a customer,  monthly and annual  statements and
confirmations  of all purchases and  redemptions  of Fund shares in a customer's
account;  transmits proxy statements,  annual reports,  updated prospectuses and
other  communications from the Trust to its customers;  and receives,  tabulates
and  transmits to the Trust proxies  executed by its  customers  with respect to
meetings  of  shareholders  of the Fund.  For  these  services,  that  financial
institution  receives  from the Fund an annual fee,  computed  daily and payable
    

                                       13

monthly, equal to 0.225% of the average daily net assets of the Fund represented
by shares owned during the period for which  payment was being made by customers
for whom that financial institution was the holder or agent of record.
    
       

                         Expense Reimbursement Agreement

   Under an agreement dated July 1, 1993, 59 Wall Street Administrators pays the
Fund's  expenses  (see "Expense  Table") other than fees paid to Brown  Brothers
Harriman & Co. under the Trust's Administration  Agreement for the Fund, subject
to reimbursement from the Fund. To accomplish such reimbursement, 59 Wall Street
Administrators  receives  an expense  reimbursement  fee from the Fund such that
after such  reimbursement  the  aggregate  expenses of the Fund,  including  the
allocation of aggregate expenses of the Portfolio,  do not exceed an agreed upon
annual rate,  currently  0.55% of the average daily net assets of the Fund. Such
expense  reimbursement  fees are  computed  daily and paid  monthly.  During the
fiscal  year  ended  June  30,  1996,  59 Wall  Street  Administrators  incurred
$1,802,856   in   expenses   on  behalf  of  the  Fund   including   shareholder
servicing/eligible   institution   fees  of  $1,618,695  and  received   expense
reimbursement fees of $1,723,274 from the Fund.

   The expense  reimbursement  fee  agreement  will  terminate on the earlier of
either (i) June 30, 1997, or (ii) the date on which the payments made thereunder
equal the prior payment of such reimbursable expenses. The Trustees of the Trust
are unable to predict  with any degree of  certainty  whether the Fund's  assets
will reach a size that will allow its aggregate  expenses to reach or drop below
0.55% of its average annual net assets. Had this expense reimbursement agreement
not been in place,  the total operating  expenses of the Fund for the year ended
June 30, 1996 would have been 0.56% of the Fund's average annual net assets.

   The  expenses  of the Fund paid by 59 Wall  Street  Administrators  under the
expense  reimbursement  agreement  include  the  shareholder  servicing/eligible
institution  fees; the  compensation of the Trustees of the Trust;  governmental
fees;  interest  charges;  taxes;  membership  dues  in the  Investment  Company
Institute allocable to the Fund; fees and expenses of independent  auditors,  of
legal  counsel  and of any  transfer  agent,  custodian,  registrar  or dividend
disbursing agent of the Fund;  insurance  premiums;  expenses of calculating the
net asset  value of shares of the Fund;  expenses  of  preparing,  printing  and
mailing  prospectuses,   reports,  notices,  proxy  statements  and  reports  to
shareholders  and  to  governmental   officers  and  commissions;   expenses  of
shareholder  meetings;  and expenses relating to the issuance,  registration and
qualification of shares of the Fund.

NET ASSET VALUE
================================================================================

   The Fund's net asset value per share 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  determination  of the  Fund's  net  asset  value  per  share  is made by
subtracting  from the value of the total assets of the Fund (i.e.,  the value of
its investment in the Portfolio and other assets) the amount of its  liabilities
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
per share of the Fund will remain  constant at $1.00.  No assurance can be given
that this goal can be achieved.

   The value of the Fund's  investment in the Portfolio is also  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  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  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. (See "Net Asset Value" in the Statement
of Additional Information.)

DIVIDENDS AND DISTRIBUTIONS
================================================================================

   All the Fund's net income and  short-term  capital gains and losses,  if any,
are declared as a dividend daily and paid monthly.

   Net income of the Fund  consists  of (i) all income  accrued on the assets of
the Fund (i.e.,  the Fund's pro rata share of the net income of the  Portfolio),
less (ii) all actual and accrued expenses of the Fund. (See "Net Asset Value".)

   Determination  of the  Fund's  net  income is made  immediately  prior to the
determination  of the net asset  value per share of the Fund at 4:00  P.M.,  New
York time on each day the New York Stock  Exchange is open for  regular  trading

                                       15
<PAGE>

and New York  banks are open for  business.  Net income for days other than such
business days is determined  as of 4:00 P.M.,  New York time on the  immediately
preceding business day. Dividends declared are payable to shareholders of record
on the date of determination.  Shares purchased through submission of a purchase
order prior to 11:00 A.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. (See "Redemption of Shares".)

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

   The net income and capital  gains and losses,  if any, of the  Portfolio  are
determined at 4:00 P.M., New York time on each business day. Net income for days
other than business  days is  determined  as of 4:00 P.M.,  New York time on the
immediately  preceding  business day. All the net income,  as defined below, and
capital gains and losses, if any, so determined are allocated pro rata among the
Fund and the other investors in the Portfolio at the time of such determination.

   For this  purpose  the net  income  of the  Portfolio  (from  the time of the
immediately preceding  determination  thereof) consists of (i) accrued interest,
accretion  of discount and  amortization  of premium on  securities  held by the
Portfolio, less (ii) all actual and accrued expenses of the Portfolio (including
the fees payable to the Investment Adviser and Administrator of the Portfolio).

TAXES
================================================================================

   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 the
Internal Revenue Code of 1986, as amended.  Accordingly, the Fund is not subject
to federal  income taxes on its net income and  realized net capital  gains that
are distributed to its 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.

   Dividends of net income (as defined under "Dividends and  Distributions") 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.

   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

                                       16
<PAGE>

to provide a correct taxpayer identification number (Social  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.

                              State and Local 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.

                                Foreign Investors

   The 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 Fund
since alternative  investments in money market  instruments would not be subject
to United States withholding tax.

                                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.

   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  6  St.  James  Avenue,  Boston,
Massachusetts 02116; its telephone number is (617) 423-0800.

   Pursuant to the Trust's  Declaration of Trust,  the Trustees have  authorized
the issuance of an unlimited number of full and fractional shares of each series
of the Trust,  one of which is the Fund. The Trustees of the Trust may divide or
combine the shares  into a greater or lesser  number of shares  without  thereby
changing the  proportionate  beneficial  interest in the Trust and may authorize
the  creation of  additional  series of shares,  the  proceeds of which would be
invested in separate,  independently managed portfolios. Currently there are two
series in addition to the Fund.

   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.

   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 of the Fund are entitled to a full vote for each full share held
and  to  a  fractional  vote  for  fractional   shares.  The  voting  rights  of
shareholders are not cumulative. Shares have no preemptive or conversion rights.
The rights of redemption are described elsewhere herein.  Shares when issued are

                                       17
<PAGE>

fully paid and nonassessable by the Trust,  except as set forth below. It is the
intention  of the Trust  not to hold  meetings  of  shareholders  annually.  The
Trustees  of  the  Trust  may  call  meetings  of  shareholders  for  action  by
shareholder  vote as may be required by the 1940 Act or as may be  permitted  by
the   Declaration  of  Trust  or  By-Laws.   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.

   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  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  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. However, the risk of a shareholder 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.
    

   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

                                       18
<PAGE>

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.

ADDITIONAL INFORMATION
================================================================================

   As used in this  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.

   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. 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. From time to time, fund rankings from various sources may be quoted.

   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.

   This Prospectus  omits certain of the information  contained in the Statement
of  Additional  Information  and  the  Registration  Statement  filed  with  the
Securities and Exchange Commission.  The Statement of Additional Information may
be obtained from 59 Wall Street Distributors without charge and the Registration
Statement  may be obtained  from the  Securities  and Exchange  Commission  upon
payment of the fee prescribed by the Rules and Regulations of the Commission.

APPENDIX
- --------------------------------------------------------------------------------
      THIS  APPENDIX  IS  INTENDED  TO PROVIDE  DESCRIPTIONS  OF THE  SHORT-TERM
SECURITIES  THE PORTFOLIO  MAY  PURCHASE.  HOWEVER,  OTHER SUCH  SECURITIES  NOT
MENTIONED  BELOW MAY BE PURCHASED FOR THE PORTFOLIO IF THEY MEET THE QUALITY AND
MATURITY GUIDELINES SET FORTH IN THE PORTFOLIO'S INVESTMENT POLICIES.
- --------------------------------------------------------------------------------

                           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

                                       20
<PAGE>

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

                                       21
<PAGE>

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 State
Street  Bank  and  Trust  Company,  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

                                       22
<PAGE>

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.

      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.

                      STATEMENT OF ADDITIONAL INFORMATION

                      THE 59 WALL STREET MONEY MARKET FUND

                 6 ST. JAMES AVENUE, BOSTON, MASSACHUSETTS 02116


          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 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 Portfolio's investment adviser
(the "Investment Adviser"). This Statement of Additional Information is not a
prospectus and should be read in conjunction with the Prospectus dated November
1, 1996, 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.  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.


                                        2

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").

          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;

          (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,

                                        3

<PAGE>



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

                                        4

<PAGE>

          (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.

          STATE AND FEDERAL RESTRICTIONS. In order to comply with certain state
and federal statutes and policies neither the Portfolio nor the Trust, on behalf
of the Fund, may 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) borrow money for any purpose in excess of 10% of its total assets
(taken at cost) (moreover, securities are not purchased at any time at which the
amount of its borrowings exceed 5% of its total assets (taken at market value)),
(ii) pledge, mortgage or hypothecate for any purpose in excess of 10% of its net
assets (taken at market value), (iii) sell any security which it does not own
unless by virtue of its ownership of other securities it has at the time of sale
a right to obtain securities, without payment of further consideration,
equivalent in kind and amount to the securities sold and provided that if such
right is conditional the sale would be made upon the same conditions, (iv)
invest for the purpose of exercising control or management, (v) purchase
securities issued by any investment company except by purchase in the open
market where no commission or profit to a sponsor or dealer results from such
purchase other than the customary broker's commission, or except when such
purchase, though not made in the open market, is part of a plan of merger or
consolidation; provided, however, that securities of any investment company are
not purchased if such purchase at the time thereof would cause more than 10% of
its total assets (taken at the greater of cost or market value) to be invested
in the securities of such issuers or would cause more than 3% of the outstanding
voting securities of any such issuer to be held for it, (vi) invest more than
10% of its net assets (taken at the greater of cost or market value) in
securities that are not readily marketable, (vii) purchase securities of any
issuer if such purchase at the time thereof would cause it to hold more than 10%
of any class of securities of such issuer, for which purposes all indebtedness
of an issuer is deemed a single class, (viii) invest more than 5% of its assets
in companies which, including predecessors, have a record of less than three
years of continuous operation, or (ix) purchase or retain in its portfolio any
securities issued by an issuer any of whose officers, directors, trustees or
security holders is an officer or Trustee of the Trust or the Portfolio, or is
an officer or partner of the Investment Adviser, if after the purchase of the
securities of such issuer, one or more of such persons owns beneficially more
than 1/2 of 1% of the shares or securities, or

                                        5

<PAGE>



both, all taken at market value, of such issuer, and such persons owning more
than 1/2 of 1% of such shares or securities together own beneficially more than
5% of such shares or securities, or both, all taken at market value. These
policies are not fundamental and may be changed without shareholder or investor
approval in response to changes in the various state and federal requirements.

          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.

TRUSTEES AND OFFICERS

          The Trustees and executive officers of the Trust and the Portfolio,

          Each Trustee and officer of the Trust listed above holds the
equivalent position with The 59 Wall Street Fund, Inc. The address of each
officer of the Trust is 6 St. James Avenue, Boston, Massachusetts 02116. Messrs.
Coolidge, Hoolahan, and Elder, and Mss. Jakuboski and Mugler also hold similar
positions with other investment companies for which affiliates of 59 Wall Street
Distributors serve as the principal underwriter.
    

          Except for Mr. Shields, no Trustee is an "interested person" of the
Trust or the Portfolio as that term is defined in the 1940 Act.

          The Trustees of the Trust receive a base annual fee of $15,000 (except
the Chairman who receives a base annual fee of $20,000) which is paid jointly by
all series of the Trust and The 59 Wall Street Fund, Inc. and allocated among
the series based upon their respective net assets. In addition, each series
which has commenced operations pays an annual fee to each Trustee of $1,000. The
aggregate compensation to each Trustee from the Trust and the Fund Complex (the
Fund Complex consists of the Trust and The 59 Wall Street Fund, Inc. which
currently consists of six series) was less than $60,000.

   
          The Trustees of the Portfolio receive a base annual fee of $12,000
(except the Chairman who receives a base annual fee of $17,000) which is paid
jointly by the U.S. Small Company Portfolio, International Equity Portfolio
together with the Portfolio (the "Portfolios") and allocated among the
Portfolios based upon their respective net assets. In addition, each Portfolio
which has commenced operations pays an annual fee to each Trustee of $1,000. The
aggregate compensation to each Trustee from the Portfolios was less than
$60,000.
    

          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 (Cayman) Limited 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

                                        9

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 October 31, 1996, 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 26,957,825
(3.41%) shares of the Fund. Brown Brothers Harriman & Co. and its affiliates
separately were able to direct the disposition of an additional 191,181,394
(24.45%) 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 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 December 13, 1995. 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").
    

                                       10

          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 0.15% of the Portfolio's average daily net assets. Prior to November 1, 1994,
Brown Brothers Harriman & Co. managed the assets of the Fund pursuant to an
Investment Advisory Agreement which was terminated by the Trust, on behalf of
the Fund, upon the Fund's investment of all of its assets in the Portfolio. For
the fiscal year ended June 30, 1996 and the period November 1, 1994 through June
30, 1995, the Portfolio incurred $1,081,720 and $614,606, respectively, for
advisory services. For the period July 1, 1994 through October 31, 1994 and the
fiscal year ended June 30, 1994, the Fund incurred $281,568 and $1,471,193 ,
respectively, for advisory services.
    

          The Glass-Steagall Act prohibits certain financial institutions from
engaging in the business of underwriting, selling or distributing securities and
from sponsoring, organizing or controlling a registered open-end investment
company continuously engaged in the issuance of its shares, such as the Fund.
There is presently no controlling precedent prohibiting financial institutions
such as Brown Brothers Harriman & Co. from performing investment advisory,
administrative or shareholder servicing/eligible institution functions. If Brown
Brothers Harriman & Co. were to terminate its Investment Advisory Agreement with
the Portfolio, or were prohibited from acting in such capacity, it is expected
that the Trustees of the Portfolio would recommend to the investors that they
approve a new investment advisory agreement for the Portfolio with another
qualified adviser. If Brown Brothers Harriman & Co. were to terminate its
Shareholder Servicing Agreement, Eligible Institution Agreement or
Administration Agreement with the Trust or were prohibited from acting in any
such capacity, its customers would be permitted to remain shareholders of the
Fund and alternative means for providing shareholder services or administrative
services, as the case may be, would be sought. In such event, although the
operation of the Trust might change, it is not expected that any shareholders
would suffer any adverse financial consequences. However, an alternative means
of providing shareholder services might afford less convenience to shareholders.

ADMINISTRATORS

          The Administration Agreements between the Trust and Brown Brothers
Harriman & Co. (dated November 1, 1993) and between the Portfolio and Brown
Brothers Harriman Trust Company (Cayman) Limited (dated December 15, 1993) will
remain in effect for two years from such respective date and thereafter, but
only so long as each such agreement is specifically approved at least annually
in the same manner as the Investment Advisory Agreement (see "Investment
Adviser"). The Independent Trustees last approved

                                       11

<PAGE>



   
the Trust's Administration Agreement and the Portfolio's Administration
Agreement on August 22, 1995 and December 13, 1995, respectively. Each agreement
will terminate automatically if assigned by either party thereto and is
terminable with respect to the Trust or the Portfolio at any time without
penalty by a vote of a majority of the Trustees of the Trust or the Trustees of
the Portfolio, as the case may be, or by a vote of the holders of a "majority of
the outstanding voting securities as defined in the 1940 Act" of the Trust or
the Portfolio, as the case may be (see "Additional Information"). The Trust's
Administration Agreement is terminable by the Trustees of the Trust or
shareholders of the Trust on 60 days' written notice to Brown Brothers Harriman
& Co. The Portfolio's Administration Agreement is terminable by the Trustees of
the Portfolio or by the Fund and other investors in the Portfolio on 60 days'
written notice to Brown Brothers Harriman Trust Company (Cayman) Limited. Each
agreement is terminable by the respective Administrator on 90 days' written
notice to the Trust or the Portfolio, as the case may be.
    

   
          The administrative fee payable to Brown Brothers Harriman & Co. from
the Fund is calculated daily and payable monthly at an annual rate equal to
0.075% of the Fund's average daily net assets. From November 1, 1993 to October
31, 1994, Brown Brothers Harriman & Co. was paid at an annual rate equal to
0.10% of the Fund's average daily net assets. Prior to November 1, 1993, 59 Wall
Street Distributors served as administrator of the Trust and was paid at an
annual rate equal to 0.05% of the Fund's average daily net assets. For the
fiscal years ended June 30, 1996, 1995, and 1994, the Fund incurred $539,565,
$494,282 and $515,818 , respectively, for administrative services.
    

   
          The administrative fee paid to Brown Brothers Harriman Trust Company
(Cayman) Limited by the Portfolio is calculated and paid monthly at an annual
rate equal to 0.035% of the Portfolio's average daily net assets. Brown Brothers
Harriman Trust Company (Cayman) Limited is a wholly-owned subsidiary of Brown
Brothers Harriman Trust Company of New York, which is a wholly-owned subsidiary
of Brown Brothers Harriman & Co. For the period October 31, 1994 through June
30, 1995 and the fiscal year ended June 30, 1996, the Portfolio incurred
$143,408 and $252,401, respectively, for administrative services.
    
   
DISTRIBUTOR

          The Distribution Agreement (dated August 31, 1990) between the Trust
and 59 Wall Street Distributors remains in effect indefinitely, but only so long
as such agreement is specifically approved at least annually in the same manner
as the Investment Advisory Agreement (see "Investment Adviser"). The
Distribution Agreement was most recently approved by the Independent Trustees of
the Trust on February 21, 1996. The agreement
    

                                       12

<PAGE>



terminates automatically if assigned by either party thereto and is terminable
with respect to the Fund at any time without penalty by a vote of a majority of
the Trustees of the Trust or by a vote of the holders of a "majority of the
outstanding voting securities as defined in the 1940 Act" of the Fund (see
"Additional Information"). The Distribution Agreement is terminable with respect
to the Fund by the Trust's Trustees or shareholders of the Fund on 60 days'
written notice to 59 Wall Street Distributors. The agreement is terminable by 59
Wall Street Distributors on 90 days' written notice to the Trust.

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 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 value of the Fund's investment in
the Portfolio is determined by multiplying the value of the Portfolio's net
assets by the percentage, effective for that day, which represents the Fund's
share of the aggregate beneficial interests in the Portfolio.

          The securities held by the Portfolio are valued at their amortized
cost. 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

                                       13

<PAGE>



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.

<PAGE>
   
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, 1996 was
4.84%. 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, 1996 was 4.95%.
    
        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.

FEDERAL TAXES

          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.

 
                                       15

<PAGE>

          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.

MASSACHUSETTS TRUST

          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
three series.

          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 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.

          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

                                       17

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 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.

          Brown Brothers Harriman & Co. does not seek profits through short-term
trading. However, Brown Brothers Harriman & Co. may on behalf of the Portfolio
dispose of any portfolio security prior to its maturity if it believes such
disposition is advisable even if this action realizes profits.

   
          Since brokerage commissions are not normally paid on investments which
are made for the Portfolio, turnover resulting from such investments should not
adversely affect the net asset value of the Portfolio. In connection with
portfolio transactions for the Portfolio, Brown Brothers Harriman & Co. intends
to seek best price and execution on a competitive basis for both purchases and
sales of securities. For the fiscal year ended June 30, 1996, the Portfolio paid
no brokerage commissions.
    
          Prior to the Fund's termination of its Investment Advisory Agreement
with Brown Brothers Harriman & Co. no brokerage commissions were paid from the
Fund during the fiscal years ended June 30, 1995 and 1994.

          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.

BOND, NOTE AND COMMERCIAL PAPER RATINGS

MOODY'S INVESTORS SERVICE, INC. ("MOODY'S")

          Aaa - Bonds rated Aaa are judged to be of the "best quality". Issues

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.

their services or from established and broad-based access to the market for
refinancing or both.

principal and interest. Issues determined to possess overwhelming safety
characteristics are given a plus (+) designation (SP-1+).

<PAGE>



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

          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.
