Notes:
(1) The purpose of this table is to assist investors in understanding the var-
    ious costs and expenses that an investment in the Funds will bear directly
    or indirectly. For the fiscal year ended December 31, 1995 no FST Pre-
    ferred Shares of the Funds had been issued. Accordingly, the costs and ex-
    penses included in the table and hypothetical example are based on esti-
    mated fees and expenses for the current fiscal year ended December 31,
    1996. The table and hypothetical example should not be considered a repre-
    sentation of past or future expenses; actual expenses may vary depending
    upon a variety of factors including the actual performance of each Fund,
    which may be greater or less than 5%. See "Management."
 
(2) The information with respect to each Fund set forth in the foregoing table
    and hypothetical example relates only to FST Preferred Shares of the
    Funds. The Funds also offer FST Shares, FST Service Shares and FST Admin-
    istration Shares which are subject to different fees and expenses (which
    affect performance) and are entitled to different services. Information
    regarding FST Shares, FST Administration Shares and FST Service Shares may
    be obtained from your sales representative or from Goldman Sachs by call-
    ing the number on the cover page of this Prospectus.
 
(3) Goldman Sachs Asset Management (the "Adviser" or "GSAM") has agreed that a
    portion of its fees will not be imposed, pursuant to applicable contracts.
    In addition, the Adviser has agreed to reduce or otherwise limit certain
    expenses of each Fund (excluding fees payable to Service Organizations, as
    defined herein, management and account administration fees, taxes, inter-
    est, brokerage and litigation, indemnification and other extraordinary ex-
    penses), on an annualized basis, to .01% of such Fund's average daily net
    assets. Had the reduction of fees otherwise payable and expense limita-
    tions not been reflected in the above table, the management fees payable
    by each Fund would be 0.075% of average daily net assets, and the esti-
    mated amount of other expenses payable by Financial Square Prime Obliga-
    tions Fund, Financial Square Money Market Fund, Financial Square Treasury
    Obligations Fund, Financial Square Government Fund, Financial Square Tax-
    Free Money Market Fund and Financial Square Municipal Money Market Fund,
    would be 0.035%, 0.045%, 0.045%, 0.045%, 0.105% and 0.29%, respectively,
    of average daily net assets. Had the reduction of fees otherwise payable
    and expense limitations not been reflected in the above table, the esti-
    mated annual operating expenses of Financial Square Prime Obligations
    Fund, Financial Square Money Market Fund, Financial Square Treasury Obli-
    gations Fund, Financial Square Government Fund, Financial Square Tax-Free
    Money Market Fund and Financial Square Municipal Money Market Fund would
    be 0.49%, 0.50%, 0.50%, 0.50%, 0.56% and 0.745%, respectively, of average
    daily net assets.
 
(4) Service Organizations (other than broker-dealers) may charge other fees to
    their customers who are the beneficial owners of FST Preferred Shares in
    connection with their customers' accounts. See "Administration." Such
    fees, if any, may affect the return such customers realize with respect to
    their investments.

                         AN INTRODUCTION TO THE FUNDS
 
  The Trust is a no-load, open-end, management investment company registered
under the Investment Company Act of 1940, as amended (the "Investment Company
Act"). Each Fund is a separate pool of assets which pursues its investment ob-
jective through separate investment policies, as described below. Goldman
Sachs Asset Management, a separate operating division of Goldman, Sachs & Co.
("Goldman Sachs"), serves as the Funds' investment adviser and administrator
(the "Adviser" or "GSAM"). Goldman Sachs, which serves as the Funds' distribu-
tor and transfer agent, is one of the largest international investment banking
and brokerage firms in the United States.
 
  The Funds are designed for institutional investors seeking a high rate of
return, a stable net asset value and convenient liquidation privileges. The
Funds are particularly suitable for banks, corporations and other financial
institutions that seek investment of short-term funds for their own accounts
or for the accounts of their customers. Each Fund seeks to maintain a stable
net asset value of $1.00 per share. To facilitate this goal, each Fund's port-
folio securities are valued by the amortized cost method as permitted by a
rule of the Securities and Exchange Commission ("SEC"). The SEC rule requires,
among other things, that all portfolio securities have at the time of purchase
a maximum remaining maturity of thirteen months and that each Fund maintain a
dollar-weighted average portfolio maturity of not more than ninety (90) days.
Investments by each Fund must present minimal credit risk.
 
  Each Fund, other than Financial Square Tax-Free Money Market Fund and Finan-
cial Square Municipal Money Market Fund, may only purchase "First Tier Securi-
ties" as defined herein. First Tier Securities are securities which are rated
(or that have been issued by an issuer that is rated with respect to a class
of short-term debt obligations, or any security within that class, comparable
in priority and quality with such securities) in the highest short-term rating
category by at least two nationally recognized statistical rating organiza-
tions ("NRSRO's"), or if only one NRSRO has assigned a rating, by that NRSRO.
 
  Securities which are unrated may be purchased only if they are deemed to be
of comparable quality to First Tier Securities or, in the case of Financial
Square Tax-Free Money Market Fund and Financial Square Municipal Money Market
Fund, "Second Tier Securities" as defined herein. Financial Square Tax-Free
Money Market Fund and Financial Square Municipal Money Market Fund may invest
in First and Second Tier Securities. Second Tier Securities are securities
rated in the top two short-term rating categories by at least two NRSROs, or
if only one NRSRO has assigned a rating, by that NRSRO, but which are not
First Tier Securities. Purchases of securities which are unrated or rated by
only one NRSRO must be approved or ratified by the Trustees, except for pur-
chases made on behalf of Financial Square Tax-Free Money Market Fund and Fi-
nancial Square Municipal Money Market Fund.
 
  NRSROs include Standard & Poor's Ratings Group, Moody's Investors Service,
Inc., Fitch Investors Service, Inc., Duff and Phelps, Inc., IBCA Limited and
its affiliate IBCA Inc., and Thomson BankWatch, Inc. For a description of each
NRSRO's rating categories, see Appendix A to the Statement of Additional In-
formation.
 
  Shares of the Government Fund are intended to qualify as eligible invest-
ments for Federally chartered credit unions pursuant to Sections 107(7),
107(8) and 107(15) of the Federal Credit Union Act, Part 703 of the National
Credit Union Administration ("NCUA") Rules and Regulations and NCUA Letter
Number 155. The Fund intends to review changes in the applicable laws, rules
and regulations governing eligible investments for federally chartered credit
unions, and to take such action as may be necessary so that the investments of
the Fund qualify as eligible investments under the Federal Credit Union Act
and the regulations thereunder. Shares of the Government Fund, however, may or
may not qualify as eligible investments for particular state chartered credit
unions. The Government Fund encourages each state chartered credit union to
consult qualified legal counsel concerning whether the Government Fund is a
permissible investment under the law applicable to it.

 INVESTMENT OBJECTIVE AND POLICIES OF FINANCIAL SQUARE PRIME OBLIGATIONS FUND
 
  The investment objective of Financial Square Prime Obligations Fund ("Prime
Obligations Fund") is to maximize current income to the extent consistent with
the preservation of capital and the maintenance of liquidity. All of Prime Ob-
ligations Fund's assets will be invested in high quality money market instru-
ments. The Fund pursues its objective by investing exclusively in the follow-
ing instruments:
 
  (A) securities issued or guaranteed as to principal and interest by the
      U.S. Government, its agencies, authorities and instrumentalities ("U.S.
      Government Securities");
 
  (B) obligations issued or guaranteed by U.S. banks (including certificates
      of deposit, commercial paper, unsecured bank promissory notes and bank-
      ers' acceptances) which have more than $1 billion in total assets at
      the time of purchase. Such obligations may also include debt obliga-
      tions issued by U.S. subsidiaries of such banks;
 
  (C) commercial paper (including variable amount master demand notes and as-
      set-backed commercial paper) issued or guaranteed by U.S. corporations,
      U.S. commercial banks, or other entities;
 
  (D) unrated notes, paper or other instruments which are determined to be of
      comparable high quality by the Adviser pursuant to criteria approved by
      the Trustees;
 
  (E) other short-term obligations issued or guaranteed by U.S. corporations,
      or other entities (including short-term funding agreements);
 
  (F) other short-term obligations issued or guaranteed by state and munici-
      pal governments (such securities may be purchased when yields on such
      securities are attractive when compared to other taxable investments);
 
  (G) asset-backed securities (including interests in pools of assets such as
      motor vehicle installment purchase obligations and credit card receiv-
      ables); and
 
  (H) repurchase agreements.
 
  Prime Obligations Fund may acquire any of the above securities on a forward
commitment or when-issued basis.
 
    INVESTMENT OBJECTIVE AND POLICIES OF FINANCIAL SQUARE MONEY MARKET FUND
 
  The investment objective of Financial Square Money Market Fund ("Money Mar-
ket Fund") is to maximize current income to the extent consistent with the
preservation of capital and the maintenance of liquidity. Money Market Fund
pursues its objective by investing in the following instruments:
 
  (A) U.S. Government Securities;
 
  (B) obligations issued or guaranteed by U.S. banks (including certificates
      of deposit, commercial paper, unsecured bank promissory notes and bank-
      ers' acceptances) which have more than $1 billion in total assets at
      the time of purchase;
 
  (C) U.S. dollar denominated obligations issued or guaranteed (including
      fixed time deposits) by foreign banks which have more than $1 billion
      in total assets at the time of purchase, U.S. branches of such foreign
      banks (Yankee obligations), foreign branches of such foreign banks, and
      foreign branches of U.S. banks having more than $1 billion in total as-
      sets at the time of purchase. Such bank obligations may be general ob-
      ligations of the parent bank or may be limited to the issuing branch by
      the terms of the specific obligation or by government regulation;
 
  (D) commercial paper (including variable amount master demand notes and as-
      set-backed commercial paper) issued or guar-
 
                                       7

     anteed by U.S. corporations, U.S. commercial banks, foreign corpora-
     tions, foreign commercial banks or other entities, payable in U.S. dol-
     lars;
 
  (E) unrated notes, paper or other instruments which are determined to be of
      comparable high quality by the Adviser pursuant to criteria approved by
      the Trustees;
 
  (F) other short-term obligations issued or guaranteed by U.S. corporations,
      foreign corporations or other entities, payable in U.S. dollars (in-
      cluding short-term funding agreements);
 
  (G) other short-term obligations issued or guaranteed by state and munici-
      pal governments (such securities may be purchased when yields on such
      securities are attractive when compared to other taxable investments);
 
  (H) U.S. dollar denominated obligations of the International Bank for Re-
      construction and Development;
 
  (I) U.S. dollar denominated obligations (limited to commercial paper and
      other notes) issued or guaranteed by the governments of or entities lo-
      cated or organized in the United Kingdom, France, Germany, Belgium, the
      Netherlands, Italy, Switzerland, Denmark, Norway, Austria, Finland,
      Spain, Ireland, Sweden, Australia, New Zealand, Japan, Cayman Islands
      and Canada. Not more than 25% of Money Market Fund's total assets will
      be invested in the securities of any one foreign government;
 
  (J) asset-backed securities (including interests in pools of assets such as
      motor vehicle installment purchase obligations and credit card receiv-
      ables); and
 
  (K) repurchase agreements.
 
  Money Market Fund may acquire any of the above securities on a forward com-
mitment or when-issued basis.
 
  Money Market Fund will invest more than 25% of the value of its total assets
in bank obligations (whether foreign or domestic) except that if adverse eco-
nomic conditions prevail in the banking industry (such as substantial losses
on loans, larger increases in non-performing assets, increased charge-offs and
losses of deposits) Money Market Fund may, for defensive purposes, temporarily
invest less than 25% of the value of its total assets in bank obligations. As
a result, Money Market Fund may be especially affected by favorable and ad-
verse developments in the banking industry.
 
  RISKS OF FOREIGN SECURITIES. Investments in foreign securities and bank ob-
ligations may present a greater degree of risk than investments in domestic
securities because of less publicly-available financial and other information,
less securities regulation, potential imposition of foreign withholding and
other taxes, war, expropriation or other adverse governmental actions. Foreign
banks and their foreign branches are not regulated by U.S. banking authori-
ties, and generally are not bound by the accounting, auditing and financial
reporting standards applicable to U.S. banks.
 
  INVESTMENT OBJECTIVE AND POLICIES OF FINANCIAL SQUARE TREASURY OBLIGATIONS
                                     FUND
 
  The investment objective of Financial Square Treasury Obligations Fund
("Treasury Obligations Fund") is to maximize current income to the extent con-
sistent with the preservation of capital and the maintenance of liquidity. The
Fund pursues its objective by limiting its investments to securities issued or
guaranteed by the U.S. Treasury, which are backed by the full faith and credit
of the U.S. Government, and repurchase agreements relating to such securities.
This investment policy may not be changed unless authorized by a majority of
the outstanding shares of the Fund. Treasury Obligations Fund may acquire any
of the above securities on a forward commitment or when-issued basis.

     INVESTMENT OBJECTIVE AND POLICIES OF FINANCIAL SQUARE GOVERNMENT FUND
 
  The investment objective of Financial Square Government Fund ("Government
Fund") is to maximize current income to the extent consistent with the preser-
vation of capital and the maintenance of liquidity. Although the Government
Fund intends to invest all of its assets in U.S. Government Securities and re-
purchase agreements relating to such securities, it pursues its objective by
investing at least 80% of its total assets in such securities. Government Fund
may acquire any of the above securities on a forward commitment or when-issued
basis.
 
  INVESTMENT OBJECTIVE AND POLICIES OF FINANCIAL SQUARE TAX-FREE MONEY MARKET
                                     FUND
 
  The investment objective of Financial Square Tax-Free Money Market Fund
("Tax-Free Fund") is to maximize current income exempt from federal income tax
to the extent consistent with preservation of capital and maintenance of li-
quidity. The Tax-Free Fund pursues its objective by investing in obligations
issued by or on behalf of states, territories and possessions of the United
States and their political subdivisions, agencies, authorities and instrumen-
talities, and the District of Columbia ("Municipal Instruments"), the interest
from which is, in the opinion of bond counsel, if any, excluded from gross in-
come for federal income tax purposes and not an item of tax preference under
the federal alternative minimum tax. Such Municipal Instruments may include:
 
  (A) fixed rate notes and similar debt instruments rated in the highest
      short-term rating category or in one of the two highest long-term rat-
      ing categories of at least one NRSRO;
 
  (B) variable and floating rate demand instruments rated (i) in the highest
      rating category for municipal notes or (ii) in one of the two highest
      rating categories for long-term instruments or (iii) in the highest
      rating category for commercial paper and municipal notes with demand
      features of at least one NRSRO;
 
  (C) tax-exempt commercial paper rated in the highest rating category of at
      least one NRSRO;
 
  (D) unrated notes, paper or other instruments which are determined to be of
      comparable high quality by the Adviser pursuant to criteria approved by
      the Trustees; and
 
  (E) municipal bonds rated in one of the two highest rating categories of at
      least one NRSRO and unrated bonds determined to be of comparable qual-
      ity by the Adviser pursuant to criteria approved by the Trustees.
 
  Tax-Free Fund may acquire any of the above securities on a forward commit-
ment or when-issued basis.
 
  As a matter of fundamental policy, at least 80% of Tax-Free Fund's net as-
sets will ordinarily be invested in Municipal Instruments. However, Tax-Free
Fund may temporarily invest more than 20% of its net assets in taxable money
market instruments for defensive purposes under extraordinary market condi-
tions. Investments in taxable money market instruments will be limited to
those meeting the quality standards of Tax-Free Fund. Tax-Free Fund will not
invest in taxable instruments other than these money market instruments.
 
 INVESTMENT OBJECTIVE AND POLICIES OF FINANCIAL SQUARE MUNICIPAL MONEY MARKET
                                     FUND
 
  The investment objective of Financial Square Municipal Money Market Fund
("Municipal Fund") is to maximize current income exempt from federal income
tax to the extent consistent with preservation of capital and maintenance of
liquidity. Municipal Fund pursues its objective by investing in Municipal In-
struments, the interest from which is, in the opinion of bond counsel, if any,
excluded from gross income for federal income tax purposes (but not necessar-
ily
 
                                       9

exempt from federal alternative minimum tax or state and local taxes). Such
Municipal Instruments may include:
 
  (A) fixed rate notes and similar debt instruments rated in the highest
      short-term rating category or in one of the two highest long-term rat-
      ing categories of at least one NRSRO;
 
  (B) variable and floating rate demand instruments rated (i) in the highest
      rating category for municipal notes or (ii) in one of the two highest
      rating categories for long-term instruments or (iii) in the highest
      rating category for commercial paper and municipal notes with demand
      features of at least one NRSRO;
 
  (C) tax-exempt commercial paper rated in the highest rating category of at
      least one NRSRO;
 
  (D) unrated notes, paper or other instruments which are determined to be of
      comparable high quality by the Adviser pursuant to criteria approved by
      the Trustees; and
 
  (E) municipal bonds rated in one of the two highest rating categories of at
      least one NRSRO and unrated bonds determined to be of comparable qual-
      ity by the Adviser pursuant to criteria approved by the Trustees.
 
  Municipal Fund may acquire any of the above securities on a forward commit-
ment or when-issued basis.
 
  As a matter of fundamental policy, at least 80% of Municipal Fund's net as-
sets will ordinarily be invested in Municipal Instruments. Municipal Fund may
invest up to 100% of total assets in private activity bonds the interest from
certain of which (and Municipal Fund's distributions of such interest), al-
though exempt from regular federal income tax, may be a preference item for
purposes of the federal alternative minimum tax. Municipal Fund may temporar-
ily invest more than 20% of its net assets in taxable money market instruments
for defensive purposes under extraordinary market conditions. Investments in
taxable money market instruments will be limited to those meeting the quality
standards of Municipal Fund. Municipal Fund will not invest in taxable instru-
ments other than these money market instruments.
 
              DESCRIPTION OF SECURITIES AND INVESTMENT TECHNIQUES
 
U.S. GOVERNMENT SECURITIES
 
  U.S. Government Securities are obligations issued or guaranteed by the U.S.
Government, its agencies, authorities or instrumentalities. Some U.S. Govern-
ment Securities, such as Treasury bills, notes and bonds, which differ only in
their interest rates, maturities and times of issuance, are supported by the
full faith and credit of the United States. Others, such as obligations issued
or guaranteed by U.S. Government agencies, authorities or instrumentalities
are supported either by (a) the full faith and credit of the U.S. Government
(such as securities of the Government National Mortgage Association), (b) the
right of the issuer to borrow from the Treasury (such as securities of the
Student Loan Marketing Association), (c) the discretionary authority of the
U.S. Government to purchase the agency's obligations (such as securities of
the Federal National Mortgage Association and the Federal Home Loan Mortgage
Corporation), or (d) only the credit of the issuer. No assurance can be given
that the U.S. Government will provide financial support to U.S. Government
agencies, authorities or instrumentalities in the future. U.S. Government Se-
curities may include zero coupon bonds. Such bonds may be purchased when
yields are attractive.
 
  Securities guaranteed as to principal and interest by the U.S. Government,
its agencies, authorities or instrumentalities are deemed to include (a) secu-
rities for which the payment of principal and interest is backed by an irrevo-
cable letter of credit issued by the U.S. Government, its agencies, authori-
ties or instrumentalities and (b) participations in loans made to
 
                                      10
<PAGE>
 
foreign governments or their agencies that are so guaranteed. The secondary
market for certain of these participations is limited. Such participations may
therefore be regarded as illiquid.
 
  Each Fund may also invest in separately traded principal and interest compo-
nents of securities guaranteed or issued by the U.S. Treasury if such compo-
nents are traded independently under the Separate Trading of Registered Inter-
est and Principal of Securities program ("STRIPS").
 
CUSTODIAL RECEIPTS
 
  Each Fund (other than Treasury Obligations Fund and Government Fund) may
also acquire securities issued or guaranteed as to principal and interest by
the U.S. Government, its agencies, authorities or instrumentalities in the
form of custodial receipts that evidence ownership of future interest pay-
ments, principal payments or both on certain notes or bonds issued by the U.S.
Government, its agencies, authorities or instrumentalities. For certain secu-
rities law purposes, custodial receipts are not considered obligations of the
U.S. Government.
 
INVESTMENT IN BANK OBLIGATIONS
 
  Because the Money Market Fund will concentrate its investments in obliga-
tions issued or guaranteed by U.S. and foreign banks, the Fund will be subject
to the risks of such concentration and, in particular, will be affected by de-
velopments in or related to the banking industry. The activities of U.S. banks
and most foreign banks are subject to comprehensive regulations which, in the
case of U.S. regulations, have undergone substantial changes in the past de-
cade. The enactment of new legislation or regulations, as well as changes in
interpretation and enforcement of current laws, may affect the manner of oper-
ations and profitability of domestic and foreign banks. Significant develop-
ments in the U.S. banking industry have included deregulation of interest
rates, increased competition from other types of financial institutions, in-
creased acquisition activity and geographic expansion and, during the late
1980's, increased numbers of bank failures. Banks may be particularly suscep-
tible to certain economic factors, such as interest rate changes and adverse
developments in the market for real estate. Fiscal and monetary policy and
general economic cycles can affect the availability and cost of funds, loan
demand and asset quality and thereby impact the earnings and financial condi-
tions of banks.
 
ASSET-BACKED AND RECEIVABLES-BACKED SECURITIES
 
  The Prime Obligations and Money Market Funds may invest in asset-backed and
receivables-backed securities. These securities represent participations in,
or are secured by and payable from, pools of assets such as motor vehicle in-
stallment sale contracts, installment loan contracts, leases of various types
of real and personal property, receivables from revolving credit (credit card)
agreements and other categories of receivables. Such asset pools are
securitized through the use of privately-formed trusts or special purpose cor-
porations. Payments or distributions of principal and interest may be guaran-
teed up to certain amounts and for a certain time period by a letter of credit
or a pool insurance policy issued by a financial institution or other credit
enhancements may be present.
 
  The Prime Obligations and Money Market Funds may invest in new types of
mortgage-related securities and in other asset-backed securities that may be
developed in the future to the extent consistent with its investment objective
and policies.
 
MUNICIPAL INSTRUMENTS
 
  Municipal notes include tax anticipation notes ("TANs"), revenue anticipa-
tion notes ("RANs"), bond anticipation notes ("BANs"), tax and revenue antici-
pation notes ("TRANs") and construction loan notes. Municipal bonds include
general obligation bonds and revenue bonds. General obligation bonds are
backed by the taxing power of the issuing municipality and are considered the
safest type of bonds. Revenue bonds are backed by the revenues of a project or
facility such as the tolls from a toll bridge.
 
                                      11
<PAGE>
 
Revenue bonds also include lease rental revenue bonds which are issued by a
state or local authority for capital projects and are secured by annual lease
payments from the state or locality sufficient to cover debt service on the
authority's obligations. To the extent that a Fund invests in unrated lease
rental revenue bonds, the Trustees will monitor on an ongoing basis the credit
quality of such bonds and the risks of cancellation of the underlying leases.
Industrial development bonds (generally referred to under current tax law as
"private activity bonds") are a specific type of revenue bond backed by the
credit and security of a private user and therefore have more potential risk.
Municipal bonds may be issued in a variety of forms, including commercial pa-
per, tender option bonds and variable and floating rate securities.
 
  A tender option bond is a Municipal Instrument (generally held pursuant to a
custodial arrangement) having a relatively long maturity and bearing interest
at a fixed rate substantially higher than prevailing short-term, tax-exempt
rates. The bond is typically issued in conjunction with the agreement of a
third party, such as a bank, broker-dealer or other financial institution,
pursuant to which such institution grants the security holder the option, at
periodic intervals, to tender its securities to the institution and receive
the face value thereof. As consideration for providing the option, the finan-
cial institution receives periodic fees equal to the difference between the
bond's fixed coupon rate and the rate, as determined by a remarketing or simi-
lar agent at or near the commencement of such period, that would cause the se-
curities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effec-
tively holds a demand obligation that bears interest at the prevailing short-
term, tax-exempt rate. However, an institution will not be obligated to accept
tendered bonds in the event of certain defaults or a significant downgrading
in the credit rating assigned to the issuer of the bond. The tender option
will be taken into account in determining the maturity of the tender option
bonds and a Fund's average portfolio maturity. There is a risk that a Fund
will not be considered the owner of a tender option bond for federal income
taxes purposes and thus will not be entitled to treat such interest as exempt
from federal income tax.
 
  Revenue Anticipation Warrants ("RAWs") are issued in anticipation of the is-
suer's receipt of revenues and present the risk that such revenues will be in-
sufficient to satisfy the issuer's payment obligations. The entire principal
amount of principal and interest on RAWs is due at maturity. RAWs have been
issued with maturities of up to 22 months. RAWs may also be repackaged as in-
struments which include a demand feature that permits the holder to put the
RAWs to a bank or other financial institution at a purchase price equal to par
plus accrued interest on each interest rate reset date.
 
  The value of floating and variable rate obligations generally is more stable
than that of fixed rate obligations in response to changes in interest rate
levels. Variable and floating rate obligations usually carry rights that per-
mit the Funds to sell them at par value plus accrued interest upon short no-
tice. The issuers or financial intermediaries providing rights to sell may
support their ability to purchase the obligations by obtaining credit with li-
quidity supports. These may include lines of credit, which are conditional
commitments to lend and letters of credit, which will ordinarily be irrevoca-
ble, both of which may be issued by domestic banks or foreign banks which have
a branch, agency or subsidiary in the United States. When considering whether
an obligation meets a Fund's quality standards, the Fund will look to the
creditworthiness of the party providing the right to sell as well as to the
quality of the obligation itself. A Fund may consider the maturity of a vari-
able or floating rate Municipal Instrument to be shorter than its ultimate
stated maturity if the Fund has the right to demand prepayment of its princi-
pal at specified intervals prior to the security's ultimate stated maturity,
subject to the conditions for using amortized cost valuation under the Invest-
ment Company Act. A Fund may purchase such variable or floating rate obliga-
tions from the issuers or may purchase certificates of participation, a type
of floating or variable rate obligation, which are interests in a pool of mu-
nicipal obligations held by a bank or other financial institution.
 
                                      12

  Tax-Free Fund does not currently intend to invest in industrial development
bonds (generally referred to under current tax law as "private activity
bonds"). Municipal Fund may invest up to 100% of its assets in private activ-
ity bonds. Private activity bonds are a specific type of revenue bond backed
by the credit and security of a private user and therefore have more potential
risk. When distributed to shareholders of Municipal Fund as "exempt-interest
dividends," the interest from such bonds would be an item of tax preference
under the federal alternative minimum tax. See "Taxes" and "Distributions." If
Tax-Free Fund's policy not to invest in private activity bonds should change
in the future, shareholders would be notified and such investments would not
exceed 20% of Tax-Free Fund's net assets.
 
  Both Municipal Fund and Tax-Free Fund may invest 25% or more of the value of
their total assets in Municipal Instruments which are related in such a way
that an economic, business or political development or change affecting one
Municipal Instrument would also affect the other Municipal Instruments. For
example, Municipal Fund and Tax-Free Fund may invest all of their respective
assets in (a) Municipal Instruments the interest on which is paid solely from
revenues from similar projects such as hospitals, electric utility systems,
multi-family housing, nursing homes, commercial facilities (including hotels),
steel companies or life care facilities, (b) Municipal Instruments whose is-
suers are in the same state or (c) industrial development obligations. Concen-
tration of a Fund's investments in Municipal Instruments in any of the forego-
ing will subject the Fund, to a greater extent than if such investment was
more limited, to the risks of adverse economic, business or political develop-
ments affecting any such state, industry or other area of concentration.
 
  Each Fund (other than Treasury Obligations Fund and Government Fund) may
purchase Municipal Instruments which are backed by letters of credit, which
will ordinarily be irrevocable, issued by domestic banks or foreign banks
which have a branch, agency or subsidiary in the United States. In addition,
such Funds may acquire securities in the form of custodial receipts which evi-
dence ownership of future interest payments, principal payments or both on ob-
ligations of certain state and local governments and authorities.
 
  In order to enhance the liquidity, stability, or quality of a Municipal In-
strument, each Fund (other than Treasury Obligations Fund and Government Fund)
may acquire the right to sell the security to another party at a guaranteed
price and date. These rights may be referred to as puts, demand features, or
standby commitments.
 
REPURCHASE AGREEMENTS
 
  Each Fund may enter into repurchase agreements with selected broker-dealers,
banks or other financial institutions. A repurchase agreement is an agreement
under which a Fund purchases securities and the seller agrees to repurchase
the securities within a particular time at a specified price. Such price will
exceed the original purchase price, the difference being income to the Fund,
and will be unrelated to the interest rate on the purchased security. A Fund's
custodian or sub-custodian will maintain custody of the purchased securities
for the duration of the agreement. The value of the purchased securities, in-
cluding accrued interest, will at all times exceed the value of the repurchase
agreement. In the event of bankruptcy of the seller or failure of the seller
to repurchase the securities as agreed, a Fund could suffer losses, including
loss of interest on or principal of the security and costs associated with de-
lay and enforcement of the repurchase agreement. In evaluating whether to en-
ter into a repurchase agreement, the Adviser will carefully consider the cred-
itworthiness of the seller pursuant to procedures reviewed and approved by the
Trustees. Distributions of the income from repurchase agreements entered into
by a Fund will be taxable to its shareholders. In addition, each Fund, to-
gether with other registered investment companies having advisory agreements
with the Adviser or any of its affiliates, may transfer uninvested cash bal-
ances into a single joint account, the daily aggregate balance of which will
be invested in one or more repurchase agreements.
 
                                      13
<PAGE>
 
FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES
 
  Each Fund may purchase when-issued securities and make contracts to purchase
or sell securities for a fixed price at a future date beyond customary settle-
ment time. A Fund is required to hold and maintain in a segregated account
with the Fund's custodian or sub-custodian until the settlement date, cash or
liquid, high quality debt obligations in an amount sufficient to meet the pur-
chase price. Alternatively, a Fund may enter into offsetting contracts for the
forward sale of other securities that it owns. Securities purchased or sold on
a when-issued or forward commitment basis involve a risk of loss if the value
of the security to be purchased declines prior to the settlement date or if
the value of the security to be sold increases prior to the settlement date.
Although a Fund would generally purchase securities on a when-issued or for-
ward commitment basis with the intention of acquiring securities for its port-
folio, the Fund may dispose of a when-issued security or forward commitment
prior to settlement if the Adviser deems it appropriate to do so.
 
OTHER INVESTMENT COMPANIES
 
  Each Fund (other than the Treasury Obligations Fund and Government Fund) may
invest in securities issued by other money market investment companies. Such
investments will be determined by the Adviser, under guidelines established by
the Trustees, to present minimal credit risks. The amount of a Fund's
investments in securities of other investment companies will be subject to the
limitations on such investments prescribed by the Investment Company Act and
certain state securities regulations. These limits include a prohibition on
any Fund acquiring more than 3% of the voting shares of any other investment
company and a prohibition on investing more than 5% of a Fund's assets in se-
curities of any one investment company or more than 10% of its assets in secu-
rities of all investment companies. Each Fund will indirectly bear its propor-
tionate share of any management fees and other expenses paid by such other in-
vestment companies. Goldman Sachs will not impose a portion of the management
fees payable by a Fund (the "Acquiring Fund") with respect to assets invested
in another money market investment company (the "Acquired Fund") as follows.
The amount of the management fees otherwise payable by the Acquiring Fund and
not imposed by Goldman Sachs will be equal to the amount of management fees
indirectly paid by the Acquiring Fund as a shareholder of the Acquired Fund.
Such other investment companies will have investment objectives, policies and
restrictions substantially similar to those of the Acquiring Fund and will be
subject to substantially the same risks.
 
                            INVESTMENT LIMITATIONS
 
  PRIME OBLIGATIONS FUND, MONEY MARKET FUND, TREASURY OBLIGATIONS FUND AND
GOVERNMENT FUND (THE "TAXABLE FUNDS"). Pursuant to SEC Rule 2a-7 under the In-
vestment Company Act, each Taxable Fund may not invest more than 5% of its as-
sets (taken at amortized cost) in the securities of any one issuer (except
U.S. Government Securities and repurchase agreements collateralized by such
securities). Each Taxable Fund may, however, invest more than 5% of its assets
in the First Tier Securities of a single issuer for a period of up to three
business days after the purchase thereof, although a Taxable Fund may not make
more than one such investment at any time. No Taxable Fund may invest in secu-
rities which are Second Tier Securities at the time of purchase. Immediately
after the acquisition of any put by a Taxable Fund, not more than 5% of such
Fund's total assets may be invested in securities issued by or subject to puts
from the same issuer. However, this limitation will not apply to the issuer of
unconditional puts if the Taxable Fund does not have more than 10% of its to-
tal assets invested in securities issued by or subject to unconditional puts
from such issuer. Pursuant to SEC Rule 2a-7, the foregoing restrictions are
not applicable to Municipal Fund and Tax-Free Fund. The foregoing operating
policies are more restrictive than the fundamental policy set forth below,
which would give a Fund the ability to invest, with respect to 25% of its as-
sets, more than 5% of its assets in any one issuer. Each Fund operates in ac-
cordance with these operating policies which comply with SEC Rule 2a-7.
 
                                      14

  MUNICIPAL FUND AND TAX-FREE FUND. Pursuant to SEC Rule 2a-7, immediately af-
ter the acquisition of any put by either Municipal Fund or Tax-Free Fund, not
more than 5% of such Fund's total assets may be invested in securities issued
by or subject to puts from the same issuer. However, this limitation applies
only with respect to 75% of each such Fund's total assets. Also, with respect
to such Funds, this limitation will not apply to an issuer of unconditional
puts if the Fund does not have more than 10% of its total assets invested in
securities issued by or subject to unconditional puts from such issuer. Each
of Municipal Fund and Tax-Free Fund will operate in accordance with this oper-
ating policy which complies with SEC Rule 2a-7.
 
INVESTMENT RESTRICTIONS
 
  The Trust, on behalf of each Fund, has adopted certain fundamental invest-
ment restrictions which are enumerated in detail in the Statement of Addi-
tional Information and which may not be changed with respect to any Fund un-
less authorized by a majority of its outstanding shares. Among other restric-
tions, a Fund may not, with respect to 75% of its total assets taken at market
value, invest more than 5% of its total assets in the securities of any one
issuer (except U.S. Government Securities and repurchase agreements collater-
alized by such securities) or acquire more than 10% of any class of the out-
standing voting securities of any one issuer. In addition, each Fund (other
than Money Market Fund as provided below) may not invest more than 25% of its
total assets in securities of issuers in any one industry (the electric, gas,
water and telephone utility industries being treated as separate industries
for the purpose of the restriction), provided that there is no 25% limitation
in respect of, and each Fund reserves freedom of action to concentrate its in-
vestments in, U.S. Government Securities, obligations (other than commercial
paper) issued or guaranteed by U.S. banks and U.S. branches of foreign banks,
provided such branches are subject to the same regulations as U.S. banks, and
repurchase agreements and loans of securities collateralized by U.S. Govern-
ment Securities or such bank obligations, provided the investment policies of
the Fund permit the particular investment. Money Market Fund will concentrate
in obligations of domestic and foreign banks, except during adverse conditions
in the banking industry. Tax diversification requirements for qualification as
a regulated investment company apply to the Funds and are in certain instances
more strict than these investment restrictions. In applying the above restric-
tions, a Fund will not treat a guarantee as a security issued by the guarantor
if the value of all securities issued or guaranteed by the guarantor and owned
by the Fund does not exceed 10% of its total assets.
 
  Each Fund may borrow money from banks only for temporary or emergency pur-
poses in an aggregate amount not exceeding one-third of the value of its total
assets. A Fund may not purchase securities while such borrowings exceed 5% of
the value of its assets. Except for such enumerated restrictions and as other-
wise indicated in this Prospectus, the investment objective and policies of
each Fund are not fundamental policies and accordingly may be changed by the
Trust's Board of Trustees without obtaining the approval of the Fund's share-
holders.
 
RESTRICTED AND OTHER ILLIQUID SECURITIES
 
  Each Fund may purchase securities that are not registered ("restricted secu-
rities") under the Securities Act of 1933 ("1933 Act"), but can be offered and
sold to "qualified institutional buyers" under Rule 144A under the 1933 Act.
However, a Fund will not invest more than 10% of its net assets in illiquid
investments, which includes fixed time deposits maturing in more than seven
days and restricted securities. Restricted securities (including commercial
paper issued pursuant to Section 4(2) of the 1933 Act) which the Board of
Trustees has determined are liquid, based upon a continuing review of the
trading markets for the specific restricted security, will not be deemed to be
illiquid investments for purposes of this restriction. The Board of Trustees
may adopt guidelines and delegate to the Adviser the daily function of deter-
mining and monitoring the liquidity of restricted securities. The Board, how-
ever, will retain sufficient oversight and be ultimately responsible for the
deter-
 
                                      15
<PAGE>
 
minations. Since it is not possible to predict with assurance that the market
for restricted securities eligible for resale under Rule 144A will continue to
be liquid, the Board will carefully monitor each Fund's investments in these
securities, focusing on such important factors, among others, as valuation,
liquidity and availability of information. This investment practice could have
the effect of increasing the level of illiquidity in each Fund to the extent
that qualified institutional buyers become for a time uninterested in purchas-
ing these restricted securities.
 
  In addition, each Fund may not invest in repurchase agreements maturing in
more than seven days and securities which are not readily marketable if, as a
result thereof, more than 10% of the net assets of the Fund (taken at market
value) would be invested in such investments. Certain repurchase agreements
which mature in more than seven days can be liquidated before the nominal
fixed term on seven days or less notice. Such repurchase agreements will be
regarded as liquid instruments.
 
                                  MANAGEMENT
 
THE ADVISER AND ADMINISTRATOR
 
  GSAM, One New York Plaza, New York, New York, a separate operating division
of Goldman Sachs, acts as investment adviser and administrator to the Funds.
Goldman Sachs registered as an investment adviser in 1981. As of January 31,
1996, Goldman Sachs, together with its affiliates, acted as investment advis-
er, administrator or distributor for approximately $57 billion in assets.
 
  As of November 25, 1995, Goldman Sachs and its consolidated subsidiaries had
assets of approximately $   billion and partners' capital of $1.9 billion and
ranked as one of the largest international investment banking and brokerage
firms in the United States. Founded in 1869, Goldman Sachs is a major player
among investment banking and brokerage firms providing a broad range of fi-
nancing and investment services both in the United States and abroad.
 
  Pursuant to an SEC order, each Taxable Fund may enter into principal trans-
actions in certain taxable money market instruments, including repurchase
agreements, with Goldman Sachs or its affiliate, Goldman Sachs Money Market,
L.P.
 
  Under the Investment Advisory Agreements, GSAM continually manages the port-
folio of each Fund, including the purchase, retention and disposition of its
securities and other assets. The management of each Fund's portfolio is sub-
ject to the supervision of the Board of Trustees and that Fund's investment
policies. For these services, GSAM is entitled to a monthly fee at an annual
rate equal to .075% of the Fund's average daily net assets.
 
  GSAM has agreed that it will not impose a portion of its advisory fee, pur-
suant to applicable contracts. For the fiscal period ended December 31, 1995,
Prime Obligations Fund, Money Market Fund, Treasury Obligations Fund, Govern-
ment Fund and Tax-Free Fund paid advisory fees at an effective annual rate of
0.04%, 0.01%, 0.04%, 0.04% and 0.00%, respectively, of average daily net as-
sets. Municipal Fund was not in operation during such period and, therefore,
paid no advisory fee.
 
  GSAM has agreed to reduce or otherwise limit certain expenses of each Fund
(excluding fees payable to Service Organizations, as defined herein, manage-
ment and account administration fees, and taxes, interest, brokerage and liti-
gation, indemnification and other extraordinary expenses) on an annualized ba-
sis to .01% of the Fund's average daily net assets. GSAM has no current inten-
tion to but may discontinue or modify any of such reductions or limitations at
its discretion.
 
  In addition, under the Trust's Administration Agreement with GSAM, GSAM ad-
ministers each Fund's business affairs subject to the supervision of the Board
of Trustees and, in connection therewith, furnishes the Funds with office fa-
cilities, bears all fees and costs of the services furnished by the transfer
agent to the Funds, and is responsible for ordinary clerical, recordkeeping
and bookkeeping functions re-
 
                                      16
<PAGE>
 
quired to be performed by the Funds (excluding those performed by each Fund's
custodian), preparation and filing of documents required to comply with fed-
eral and state securities laws, supervising the activities of the Funds' cus-
todian and transfer agent, providing assistance in connection with meetings of
the Board of Trustees and shareholders and other administrative services nec-
essary to conduct each Fund's business.
 
  For those administrative services and facilities each Fund pays an account
administration fee to GSAM. The account administration fee is charged and al-
located to each shareholder account daily in the amount equal on an annual ba-
sis to .13% of the Fund's average daily net assets. For the fiscal period
ended December 31, 1995, Prime Obligations Fund, Money Market Fund, Treasury
Obligations Fund, Government Fund and Tax-Free Fund paid GSAM a fee for ac-
count administration services at the foregoing annual rate.
 
THE DISTRIBUTOR AND TRANSFER AGENT
 
  Goldman Sachs, 4900 Sears Tower, Chicago, Illinois 60606, serves as the Dis-
tributor of shares of each Fund pursuant to a Distribution Agreement with the
Trust. The Distributor will assist in the sale of shares of each Fund upon the
terms described herein. Goldman Sachs also serves as the Transfer Agent of
each Fund.
 
                                     TAXES
 
  Each Fund is treated as a separate entity for federal income tax purposes
and intends to qualify and be treated as a regulated investment company under
Subchapter M of the Internal Revenue Code of 1986 (the "Code") for each tax-
able year. To qualify as such, each Fund must satisfy certain requirements re-
lating to the sources of its income, diversification of its assets and distri-
bution of its income to shareholders. As a regulated investment company, each
Fund will not be subject to federal income or excise tax on any net investment
income and net realized capital gains that are distributed to its shareholders
in accordance with certain timing requirements of the Code.
 
  Dividends paid by a Fund from net investment income (except, in the case of
Tax-Free Fund and Municipal Fund, tax-exempt interest), the excess of net
short-term capital gain over net long-term capital loss and taxable original
issue discount or market discount income will be taxable to shareholders as
ordinary income. Dividends paid by a Fund from the excess of net long-term
capital gain over net short-term capital loss will be taxable as long-term
capital gain regardless of how long the shareholders have held their shares.
These tax consequences will apply to taxable distributions of a Fund (includ-
ing a Fund that also pays exempt-interest dividends, as described below) re-
gardless of whether distributions are received in cash or reinvested in
shares. Certain distributions paid by the Funds in January of a given year
will be taxable to shareholders as if received on December 31 of the year in
which they are declared. Shareholders will be informed annually about the
amount and character of distributions received from the Funds for federal in-
come tax purposes, including any distributions that may constitute a return of
capital or any distribution of Municipal Fund that may constitute a tax pref-
erence item under the federal alternative minimum tax.
 
  Municipal Fund and Tax-Free Fund each intends to satisfy certain require-
ments of the Code for the payment of "exempt-interest dividends" not included
in shareholders' federal gross income. Dividends paid by these Funds from in-
terest on tax-exempt obligations and properly designated by the Funds as ex-
empt-interest dividends, including exempt-interest dividends received from
other regulated investment companies, will generally be exempt from federal
income tax, although a portion of such dividends may be subject to the federal
alternative minimum tax. Exempt-interest dividends will be considered in com-
puting the "adjusted current earnings" preference item for purposes of the
corporate federal alternative minimum tax, the corporate environmental tax,
and the extent, if any, to which social security or railroad retirement bene-
fits are taxable. Persons
 
                                      17
<PAGE>
 
who are "substantial users" of facilities financed by certain industrial de-
velopment or private activity bonds should consult their own tax advisers be-
fore purchasing shares of these Funds. Interest incurred to purchase or carry
shares of these Funds will not be deductible for federal income tax purposes
to the extent related to exempt-interest dividends paid by the Funds and may
not be deductible in whole or in part for state income tax purposes.
 
  Individuals and certain other classes of shareholders may be subject to 31%
backup withholding of federal income tax on taxable distributions if they fail
to furnish their correct taxpayer identification number and certain certifica-
tions or if they are otherwise subject to backup withholding. Individuals,
corporations and other shareholders that are not U.S. persons under the Code
are subject to different tax rules and may be subject to nonresident alien
withholding at the rate of 30% (or a lower rate provided by an applicable tax
treaty) on amounts treated as ordinary dividends from the Funds.
 
  If a Fund invests in foreign securities, it may be subject to foreign with-
holding or other foreign taxes on income earned on such securities and is ex-
pected to be unable to pass such taxes through to shareholders, who therefore
are not expected to include such taxes in income or be entitled to claim for-
eign tax credits or deductions with respect to such taxes.
 
  In addition to federal taxes, a shareholder may be subject to state, local
or foreign taxes on payments received from a Fund. A state income (and possi-
bly local income and/or intangible property) tax exemption is generally avail-
able to the extent a Fund's distributions are derived from interest on (or, in
the case of intangibles taxes, the value of its assets is attributable to)
certain U.S. Government obligations and/or tax-exempt municipal obligations
issued by or on behalf of the particular state or a political subdivision
thereof, provided in some states that certain thresholds for holdings of such
obligations and/or reporting requirements are satisfied. Shareholders should
consult their own tax advisers concerning these matters.
 
                                NET ASSET VALUE
 
  The net asset value of each Fund (except Government Fund) is determined as
of the close of regular trading on the New York Stock Exchange (normally 4:00
p.m. New York time) on each Business Day. The net asset value of Government
Fund is determined as of 5:00 p.m. New York time on each Business Day. Net as-
set value per share for each class of shares of each Fund is calculated by de-
termining the amount of net assets attributable to each class of shares and
dividing by the number of shares for such class.
 
  On any Business Day, as defined herein, when the Public Securities Associa-
tion ("PSA") recommends that the securities market close early, each Fund re-
serves the right to cease accepting purchase and redemption orders for same
Business Day credit at the time PSA recommends that the securities market
close. On days any Fund closes early, purchases and redemption orders received
after the PSA recommended closing time will be credited for the next Business
Day. In addition, each Fund reserves the right to advance the time by which
purchase and redemption orders must be received for same Business Day credit
as permitted by the SEC.
 
  Each Fund's portfolio securities are valued at their amortized cost, which
does not take into account unrealized securities gains or losses. This method
involves initially valuing an instrument at its cost and thereafter assuming a
constant amortization to maturity of any premium paid or discount received.
 
                               YIELD INFORMATION
 
  From time to time, each Fund may advertise its yield and effective yield.
The yield of a Fund refers to the income generated by an investment in that
Fund over a seven-day period (which period will be stated in the advertise-
ment). 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 effec-
 
                                      18
<PAGE>
 
tive yield is calculated similarly but, when annualized, the income earned by
an investment in the Fund is assumed to be reinvested. The effective yield
will be slightly higher than the yield because of the compounding effect of
this assumed reinvestment.
 
  Municipal Fund and Tax-Free Fund may each also quote tax-equivalent yield.
Each Fund's tax-equivalent yield is calculated by determining the rate of re-
turn that would have to be achieved on a fully taxable investment to produce
the after-tax equivalent of the Fund's yield, assuming certain tax brackets
for a shareholder.
 
  Investors should note that the investment results of a Fund are based on
historical performance and will fluctuate over time. Any presentation of a
Fund's yield, effective yield or tax-equivalent yield for any prior period
should not be considered a representation of what an investment may earn or
what a Fund's yield, effective yield or tax-equivalent yield may be in any fu-
ture period.
 
  Yield, effective yield and tax-equivalent yield will be calculated sepa-
rately for FST Shares, FST Preferred Shares, FST Administration Shares and FST
Service Shares. Because each such class of shares is subject to different ex-
penses, the net yield of such classes of a Fund for the same period may dif-
fer. See "Organization and Shares of the Trust" below.
 
                     ORGANIZATION AND SHARES OF THE TRUST
 
  The Trust was formed as a business trust under the laws of The Commonwealth
of Massachusetts on December 6, 1978. The Trustees of the Trust are responsi-
ble for the overall management and supervision of its affairs. The Declaration
of Trust authorizes the Trustees to classify or reclassify any series or port-
folio of shares into one or more classes. The Trustees have authorized the is-
suance of four classes of shares of each of the Funds, which are: FST Shares,
FST Preferred Shares, FST Administration Shares and FST Service Shares. (In-
stitutions that provide services to holders of FST Preferred Shares, FST Ad-
ministration or Service Shares are referred to in this Prospectus as "Service
Organizations").
 
  When issued, shares are fully paid and nonassessable by the Trust. In the
event of liquidation, shareholders are entitled to share pro rata in the net
assets of the applicable Fund available for distribution to such shareholders.
Shares entitle their holders to one vote per share, are freely transferable
and have no preemptive, subscription or conversion rights.
 
  Shares of a Fund will be voted separately by Fund with respect to matters
pertaining to that Fund except for the election of Trustees and ratification
of independent accountants. For example, shareholders of each Fund are re-
quired to approve the adoption of any investment advisory agreement relating
to that Fund and any changes in fundamental investment restrictions or poli-
cies of such Fund. Approval by the shareholders of one Fund is effective only
as to that Fund.
 
  The Trust does not intend to hold annual shareholder meetings, although spe-
cial meetings may be called for such purposes as electing or removing Trust-
ees, complying with a requirement of the Investment Company Act, or such other
purposes as are set forth above. The Trust will facilitate shareholder commu-
nication as required and in the manner prescribed by Section 16(c) of the In-
vestment Company Act.
 
                                ADMINISTRATION
 
  Each Fund has adopted a Preferred Administration Plan with respect to the
FST Preferred Shares which authorizes it to compensate Service Organizations
for providing account administration services to their customers who are bene-
ficial owners of such Shares. Each Fund will enter into agreements with Serv-
ice Organizations which purchase FST Preferred Shares on behalf of their cus-
tomers ("Service Agreements"). The Service Agreements will provide for compen-
sation to the Service Organization in an amount up to .10 of 1% (on an
 
                                      19
<PAGE>
 
annualized basis) of the average daily net asset value of the FST Preferred
Shares of that Fund attributable to or held in the name of the Service Organi-
zation for its customers. The services provided by a Service Organization may
include acting, directly or through an agent, as the sole shareholder of rec-
ord, maintaining account records for its customers, and processing orders to
purchase and redeem FST Preferred Shares for its customers.
 
  Holders of FST Preferred Shares of a Fund will bear all expenses and fees
paid to Service Organizations with respect to such Shares as well as any other
expenses which are directly attributable to such Shares.
 
  Service Organizations (other than broker-dealers) may charge other fees to
their customers who are the beneficial owners of FST Preferred Shares in con-
nection with their customer accounts. These fees would be in addition to any
amounts received by the Service Organization under a Service Agreement and may
affect an investor's return with respect to an investment in a Fund.
 
  All inquiries of beneficial owners of FST Preferred Shares of the Funds
should be directed to such owners' Service Organization.
 
                              PURCHASE OF SHARES
 
  It is expected that all direct purchasers of FST Preferred Shares will be
Service Organizations or their nominees, which may purchase FST Preferred
Shares of the Funds through Goldman Sachs. Customers of Service Organizations
may invest in such shares only through their Service Organizations.
 
  As set forth below, FST Preferred Shares of the Funds may be purchased on
any Business Day at the net asset value next determined after receipt from the
Service Organization of both the purchase order and the purchase price in Fed-
eral Funds. Purchase orders may be made by telephoning Goldman Sachs at 800-
621-2550 or by a written request addressed to Goldman Sachs, Attention: Share-
holder Services, Goldman Sachs Money Market Trust, 4900 Sears Tower, Chicago,
Illinois 60606. It is strongly recommended that payment be effected by wiring
Federal Funds to The Northern Trust Company ("Northern"), Chicago, Illinois,
as the sub-custodian for State Street Bank and Trust Company ("State Street").
 
  Purchases of FST Preferred Shares may also be made by a Service Organization
by delivering a Federal Reserve draft or check payable to the appropriate Fund
and drawn on a U.S. bank to Goldman Sachs, Attention: Shareholder Services,
Goldman Sachs Money Market Trust, 4900 Sears Tower, Chicago, Illinois 60606.
It is expected that Federal Reserve drafts will ordinarily be converted to
Federal Funds on the day of receipt and that checks will be converted to Fed-
eral Funds within two Business Days after receipt. FST Preferred Shares pur-
chased by check may not be redeemed until the check has cleared, as described
under "Redemption of Shares."
 
  The Service Organizations are responsible for timely transmittal of purchase
orders to Goldman Sachs and Federal Funds to Northern. In order to facilitate
timely transmittal, the Service Organizations have established times by which
purchase orders and Federal Funds must be received by them.

  A Business Day means any day on which the New York Stock Exchange is open,
except for days on which Chicago, Boston or New York banks are closed for lo-
cal holidays.
 
  FST Preferred Shares of a Fund are purchased at the net asset value per
share without the imposition of a sales charge.
 
  Goldman Sachs, as each Fund's transfer agent, will maintain a complete rec-
ord of transactions and FST Preferred Shares held in each record holder's ac-
count.
 
  The Trust and Goldman Sachs each reserves the right to reject any purchase
order for any reason.
 
  Goldman Sachs may, at its own expense, provide compensation to certain deal-
ers whose customers purchase significant amounts of shares of a Fund. The
amount of such compensation may be made on a one-time and/or periodic basis,
and may be up to
 
                                      21
<PAGE>
 
25% of the annual fees that are earned by GSAM as investment adviser to such
Fund (after adjustments) and are attributable to shares held by such custom-
ers. Such compensation will not represent an additional expense to the Fund or
its shareholders, since it will be paid from assets of Goldman Sachs or its
affiliates.
 
MINIMUM INVESTMENT AND OTHER INFORMATION
 
  The minimum requirement for investing in a Fund is $50 million ($10 million
if an investor satisfies the minimum initial investment in any other Fund).
The Trust and Goldman Sachs each reserves the right to waive the minimum in-
vestment requirement. A Service Organization may impose a minimum amount for
initial and subsequent investments in FST Preferred Shares of the Funds, and
may establish other requirements such as a minimum account balance. A Service
Organization may effect redemptions of noncomplying accounts, and may impose a
charge for any special services rendered to its customers. Customers should
contact their Service Organizations for further information concerning such
requirements and charges. A Service Organization may purchase FST Preferred
Shares in connection with sweep account programs.
 
SUBSEQUENT INVESTMENTS
 
  There is no minimum amount required for subsequent investments. Orders for
the purchase of additional FST Preferred Shares should be accompanied by in-
formation identifying the account in which FST Preferred Shares are to be pur-
chased.
 
                            REPORTS TO SHAREHOLDERS
 
  The Trust will issue an annual report containing audited financial state-
ments and a semi-annual report to record holders of FST Preferred Shares of
each Fund, including Service Organizations who hold such Shares for the bene-
fit of their customers. Upon request, a printed confirmation for each transac-
tion will be provided by Goldman Sachs. Any dividends and distributions paid
by the Funds are also reflected in regular statements issued by Goldman Sachs
to shareholders of record. The Service Organizations, as record holders of FST
Preferred Shares, will be responsible for providing similar services to their
own customers who are the beneficial owners of such Shares. For example, Serv-
ice Organizations are responsible for providing each customer exercising
investment discretion with monthly statements with respect to such customer's
account in lieu of an immediate confirmation of each transaction.
 
                                 DISTRIBUTIONS
 
  All or substantially all of each Fund's net investment income will be de-
clared daily (as of 4:00 p.m. New York Time for each Fund other than Govern-
ment Fund and as of 5:00 p.m. New York time for Government Fund) as a dividend
and distributed to Service Organizations, as record owners of FST Preferred
Shares, monthly. Distributions will be made in additional FST Preferred Shares
of the same Fund or, at the election of a Service Organization, in cash. The
election to reinvest dividends and distributions or receive them in cash may
be changed by a Service Organization at any time upon written notice to
Goldman Sachs. If no election is made, all dividends and capital gain distri-
butions will be reinvested. Dividends will be reinvested as of the last calen-
dar day of each month. Cash distributions will be paid on or about the first
business day of each month. Net short-term capital gains, if any, will be dis-
tributed in accordance with the requirements of the Code and may be reflected
in the Fund's daily distributions. Each Fund may distribute at least annually
its long-term capital gains, if any, after reduction by available capital
losses. In order to avoid excessive fluctuations in the amount of monthly cap-
ital gains distributions, a portion of any net capital gains realized on the
disposition of securities during the months of November and December may be
distributed during the subsequent calendar year. Although realized gains and
losses on the assets of a Fund are reflected in the net asset value of the
Fund, they are not expected to be of an amount which would affect the Fund's
net asset value of $1.00 per share.
 
 
                                      22
<PAGE>
 
  A Fund's net investment income consists of the excess of (i) accrued inter-
est or discount (including both original issue and market discount on taxable
securities) on portfolio securities, and (ii) any income of the Fund from
sources other than capital gains over (iii) the amortization of market premium
on all portfolio securities and (iv) the estimated expenses of the Fund, in-
cluding a proportionate share of the general expenses of the Trust.
 
                                   EXCHANGES
 
  FST Preferred Shares of each Fund may be exchanged by Service Organizations
for FST Preferred Shares of any other Financial Square Fund at the net asset
value next determined either by writing to Goldman Sachs, Attention: Share-
holder Services, Goldman Sachs Money Market Trust, 4900 Sears Tower, Chicago,
Illinois 60606 or, if previously elected in the Account Information Form, by
calling Goldman Sachs at 800-621-2550. All telephone exchanges must be regis-
tered in the same name(s) and with the same address as are registered in the
Fund from which the exchange is being made. It may be difficult to implement
the telephone exchange privilege in times of drastic economic or market
changes. In an effort to prevent unauthorized or fraudulent exchange requests
by telephone, Goldman Sachs employs reasonable procedures as set forth under
"Redemption of Shares" to confirm that such instructions are genuine. Ex-
changes are available only in states where the exchange may legally be made.
The exchange privilege may be modified or withdrawn at any time on 60 days'
written notice.
 
                             REDEMPTION OF SHARES
 
HOW TO REDEEM
 
  Customers of Service Organizations may redeem FST Preferred Shares of a Fund
through their respective Service Organizations. The Service Organizations are
responsible for the transmittal of redemption requests by their customers to
Goldman Sachs. In order to facilitate timely transmittal of redemption re-
quests, Service Organizations have established procedures by which redemption
requests must be made and times by which redemption requests must be received
by them. Additional documentation may be required when deemed appropriate by a
Service Organization.
 
  A Service Organization as the record holder of FST Preferred Shares may then
redeem such Shares without charge upon request on any Business Day at the net
asset value next determined after receipt by Goldman Sachs of the redemption
request. Redemption requests may be made by telephoning Goldman Sachs at 800-
621-2550 or by a written request addressed to Goldman Sachs, Attention: Share-
holder Services, Goldman Sachs Money Market Trust, 4900 Sears Tower, Chicago,
Illinois 60606. A Service Organization may request redemptions by telephone
only if the optional telephone redemption privilege has been elected on the
Account Information Form. It may be difficult to implement redemptions by tel-
ephone in times of drastic economic or market changes.
 
  In an effort to prevent unauthorized or fraudulent redemption requests by
telephone, Goldman Sachs employs reasonable procedures specified by the Trust
to confirm that such instructions are genuine. Among other things, any redemp-
tion request that requires money to go to an account or address other than
that designated on the Account Information Form must be in writing and signed
by an authorized person designated on the Account Information Form. Any such
written request is also confirmed by telephone with both the requesting party
and the designated bank account to verify instructions. Other procedures may
be implemented from time to time. If reasonable procedures are not implement-
ed, the Trust may be liable for any loss due to unauthorized or fraudulent
transactions. In all other cases, neither the Trust nor Goldman Sachs will be
responsible for the authenticity of redemption instructions received by tele-
phone.
 
  Additional documentation may be required by Goldman Sachs in order to estab-
lish that a redemp-
 
                                      23
<PAGE>
 
tion request has been properly authorized. A redemption request will not be
considered to have been received in proper form until such additional documen-
tation has been submitted to Goldman Sachs by the recordholder of FST Pre-
ferred Shares. The payment of redemption proceeds for FST Preferred Shares re-
cently purchased by check will be delayed for up to 15 days until the check
has cleared.
PAYMENT OF REDEMPTION PROCEEDS AND DIVIDENDS
 
  In accordance with the following, redemption proceeds will be wired to the
record holder of FST Preferred Shares.

  After a wire has been initiated by Goldman Sachs, neither Goldman Sachs nor
the Trust assumes any further responsibility for the performance of intermedi-
aries or the FST Administration Shareholder's Service Organization in the
transfer process. If a problem with such performance arises, the FST Adminis-
tration Shareholder should deal directly with such intermediaries or Service
Organization.
 
  The Funds will arrange for the proceeds of redemptions effected by any means
to be wired as Federal Funds to the bank account designated in the Account In-
formation Form. As set forth above, redemption proceeds will normally be wired
on the same Business Day, but may be paid up to three Business Days after re-
ceipt of a properly executed redemption request. For example, payment may be
 
                                      24
<PAGE>
 
delayed if the Federal Reserve Bank is closed on the day redemption proceeds
would ordinarily be wired.
 
OTHER REDEMPTION INFORMATION
 
  A minimum account balance of $50 million in a Fund ($10 million if an in-
vestor satisfies the minimum initial investment in any other Fund) is required
to remain a FST Preferred Shareholder. A Fund may redeem all of the FST Pre-
ferred Shares of any FST Preferred Shareholder whose account in that Fund has
a net asset value which is less than the minimum described above. The Trust
will give sixty (60) days' prior written notice to such Shareholders whose FST
Preferred Shares are being redeemed to allow them to purchase sufficient addi-
tional FST Preferred Shares of the Fund to avoid such redemption.

("Plus Fund")and Financial Square Municipal Money Market Fund (Municipal
Fund)(individually, a "Fund" and collectively the "Funds").     

     Goldman Sachs Asset Management ("GSAM" or the "Adviser"), a separate
operating division of Goldman, Sachs & Co. ("Goldman Sachs"), serves as the
Funds' investment adviser and administrator.  Goldman Sachs serves as the Funds'
distributor and transfer agent.

     The Goldman Sachs Mutual Funds Group ("MFG") offers banks, corporate cash
managers, investment advisers and other institutional investors a family of
professionally-managed mutual funds, including money market, fixed income and

     The hallmark of MFG is personalized service, which reflects the priority
that Goldman Sachs places on serving clients' interests.  As Goldman Sachs
clients, shareholders will be assigned an Account Administrator ("AA"), who is
ready to help shareholders with questions concerning their accounts.  During
business hours, service organizations can call their AA through a toll-free
number to place purchase or redemption orders or obtain Fund and account
information.  The AA can also answer inquiries about rates of return and
portfolio composition and holdings, and guide service organizations through
operational details.  A Goldman Sachs client can also utilize the SMART/SM/
personal computer software system which allows shareholders to purchase or
redeem shares and also obtain Fund and account information directly.

                INVESTMENT POLICIES AND PRACTICES OF THE FUNDS


The following discussion elaborates on the description of each Fund's investment
policies and practices contained in the Prospectus:

U.S. GOVERNMENT SECURITIES
- --------------------------

Each Fund may invest in separately traded principal and interest components of
securities issued or guaranteed by the U.S. Treasury.  The principal and
interest components of selected securities are traded independently under the
Separate Trading of Registered Interest and Principal of Securities program
("STRIPS").  Under the STRIPS program, the principal and interest components are
individually numbered and separately issued by the U.S. Treasury at the request
of depository financial institutions, which then trade the component parts
independently.

CUSTODIAL RECEIPTS
- ------------------

Each Fund (other than Treasury Obligations Fund and Government Fund) may also
acquire custodial receipts that evidence ownership of future interest payments,
principal payments or both on certain U.S. Government notes or bonds.  Such
notes and bonds are held in custody by a bank on behalf of the owners.  These
custodial receipts are known by various names, including "Treasury Receipts,"
"Treasury Investors Growth Receipts" ("TIGR's"), and "Certificates of Accrual on
Treasury Securities" ("CATS").  Although custodial receipts are not considered
U.S. Government securities for certain securities law purposes, they are
indirectly issued or guaranteed as to principal and interest by the U.S.
Government, its agencies, authorities or instrumentalities.

BANK AND CORPORATE OBLIGATIONS
- ------------------------------

Each Fund (other than Treasury Obligations Fund and Government Fund) may invest
in commercial paper.  Commercial paper represents short-term unsecured
promissory notes issued in bearer form by banks or bank holding companies,
corporations, and finance companies.  The commercial paper purchased by the
Funds consists of direct U.S. dollar denominated obligations of domestic, or in
the case of Money Market Fund, foreign issuers.  Bank obligations in which the
Funds may invest include certificates of deposit, bankers' acceptances, fixed
time deposits and bank notes.  Certificates of deposit are negotiable
certificates issued against funds deposited in a commercial bank for a definite
period of time and earning a specified return.

Bankers' acceptances are negotiable drafts or bills of exchange, normally drawn
by an importer or exporter to pay for specific merchandise, which are "accepted"
by a bank, meaning, in effect, that the bank unconditionally agrees to pay the
face value of the instrument on maturity.  Fixed time deposits are bank
obligations
<PAGE>
 
payable at a stated maturity date and bearing interest at a fixed rate.  Fixed
time deposits may be withdrawn on demand by the investor, but may be subject to
early withdrawal penalties which vary depending upon market conditions and the
remaining maturity of the obligation.  There are no contractual restrictions on
the right to transfer a beneficial interest in a fixed time deposit to a third
party, although there is no market for such deposits.  Bank notes and bankers'
acceptances rank junior to domestic deposit liabilities of the bank and pari
passu with other senior, unsecured obligations of the bank.  Bank notes are not
insured by the Federal Deposit Insurance Corporation or any other insurer.
Deposit notes are insured by the Federal Deposit Insurance Corporation only to
the extent of $100,000 per depositor per bank.

Prime Obligations Fund, Plus Fund and Money Market Fund may invest in funding
agreements.  A funding agreement is a contract between an issuer and a purchaser
that obligates the issuer to pay a guaranteed rate of interest on a principal
sum deposited by the purchaser.  Funding agreements will also guarantee the
return of principal and may guarantee a stream of payments over time.  A funding
agreement has a fixed maturity date and may have either a fixed rate or variable
interest rate that is based on an index and guaranteed for a set time period.
Because there is no secondary market for these investments, any such funding
agreement purchased by a Fund will be regarded as illiquid.

REPURCHASE AGREEMENTS
- ---------------------

Each Fund (other than Treasury Obligations Fund) may enter into repurchase
agreements with selected broker-dealers, banks or other financial institutions.
Treasury Obligations Fund may enter into repurchase agreements only with primary
dealers in U.S. Government Securities.  A repurchase agreement is an arrangement
under which the purchaser (i.e., the Fund) purchases a U.S. Government security
or other high quality short-term debt obligation (the "Obligation") and the
seller agrees, at the time of sale, to repurchase the Obligation at a specified
time and price.

Custody of the Obligation will be maintained by the Funds' custodian or
subcustodian.  The repurchase price may be higher than the purchase price, the
difference being income to the Fund, or the purchase and repurchase prices may
be the same, with interest at a stated rate due to the Fund together with the
repurchase price on repurchase.  In either case, the income to a Fund is
unrelated to the interest rate on the Obligation subject to the repurchase
agreement.

Repurchase agreements pose certain risks for all entities, including the Funds,
that utilize them. Such risks are not unique to the Funds but are inherent in
repurchase agreements.  The Funds seek to minimize such risks by, among others,
the means


                                       2
<PAGE>
 
indicated below, but because of the inherent legal uncertainties involved in
repurchase agreements, such risks cannot be eliminated.

For purposes of the Investment Company Act of 1940, as amended (the "Investment
Company Act"), and, generally for tax purposes, a repurchase agreement is deemed
to be a loan from a Fund to the seller of the Obligation.  It is not clear
whether for other purposes a court would consider the Obligation purchased by a
Fund subject to a repurchase agreement as being owned by a Fund or as being
collateral for a loan by the Fund to the seller.

If, in the event of bankruptcy or insolvency proceedings against the seller of
the Obligation, a court holds that a Fund does not have a perfected security
interest in the Obligation, a Fund may be required to return the Obligation to
the seller's estate and be treated as an unsecured creditor of the seller.  As
an unsecured creditor, a Fund would be at risk of losing some or all of the
principal and income involved in the transaction.  To minimize this risk, the
Funds utilize custodians and subcustodians that the Adviser believes follow
customary securities industry practice with respect to repurchase agreements,
and the Adviser analyzes the creditworthiness of the obligor, in this case the
seller of the Obligation.  But because of the legal uncertainties, this risk,
like others associated with repurchase agreements, cannot be eliminated.

Also, in the event of commencement of bankruptcy or insolvency proceedings with
respect to the seller of the Obligation before repurchase of the Obligation
under a repurchase agreement, a Fund may encounter delay and incur costs before
being able to sell the security.  Such a delay may involve loss of interest or a
decline in the price of the Obligation.

Apart from risks associated with bankruptcy or insolvency proceedings, there is
also the risk that the seller may fail to repurchase the security.  However, if
the market value of the Obligation subject to the repurchase agreement becomes
less than the repurchase price (including accrued interest), the Fund will
direct the seller of the Obligation to deliver additional securities so that the
market value of all securities subject to the repurchase agreement equals or
exceeds the repurchase price.

Certain repurchase agreements which mature in more than seven days can be
liquidated before the nominal fixed term on seven days or less notice.  Such
repurchase agreements will be regarded as liquid instruments.

In addition, the Funds, together with other registered investment companies
having advisory agreements with the Adviser or any of its affiliates, may
transfer uninvested cash balances into a


                                       3
<PAGE>
 
single joint account, the daily aggregate balance of which will be invested in
one or more repurchase agreements.

FOREIGN SECURITIES
- ------------------

Money Market Fund and Plus Fund may invest in foreign securities and in
certificates of deposit, bankers' acceptances and fixed time deposits and other
obligations issued by major foreign banks, foreign branches of U.S. banks, U.S.
branches of foreign banks and foreign branches of foreign banks.  Investments
can include fixed time deposits in Cayman Island branches of such banks.  Tax-
Free Fund and Municipal Fund may also invest in municipal instruments backed by
letters of credit issued by certain of such banks.  Under current Securities and
Exchange Commission ("SEC") rules relating to the use of the amortized cost
method of portfolio securities valuation, Money Market Fund and Plus Fund are
restricted to purchasing U.S. dollar denominated securities, but they are not
otherwise precluded from purchasing securities of foreign issuers.

Investments in foreign securities and bank obligations may involve
considerations different from investments in domestic securities due to limited
publicly available information; non-uniform accounting standards; the possible
imposition of withholding or confiscatory taxes; the possible adoption of
foreign governmental restrictions affecting the payment of principal and
interest; expropriation; or other adverse political or economic developments.
In addition, it may be more difficult to obtain and enforce a judgment against a
foreign issuer or a foreign branch of a domestic bank.

ASSET-BACKED AND RECEIVABLES-BACKED SECURITIES
- ----------------------------------------------
    
Each of Prime Obligations Fund, Money Market Fund and Plus Fund may invest up to
5% of  net assets in asset-backed and receivables-backed securities.  Asset-
backed and receivables-backed securities represent participations in, or are
secured by and payable from, pools of assets such as motor vehicle installment
sale contracts, installment loan contracts, leases of various types of real and
personal property, receivables from revolving credit (credit card) agreements,
corporate securities and other categories of receivables.  Such asset pools are
securitized through the use of privately-formed trusts or special purpose
vehicles.  Payments or distributions of principal and interest may be guaranteed
up to certain amounts and for a certain time period by a letter of credit or a
pool insurance policy issued by a financial institution, or other credit
enhancements may be present.  The value of a Fund's investments in asset-backed
and receivables-backed securities may be adversely affected by prepayment of the
underlying obligations.  In addition, the risk of prepayment may cause the value
of these investments to be more     


                                       4
<PAGE>
 
    
volatile than Prime Obligations, Money Market or Plus Funds' other investments.

Through the use of trusts and special purpose corporations, various types of
assets, including automobile loans, computer leases, trade receivables and
credit card receivables, are being securitized in pass-through structures
similar to the mortgage pass-through structures.  Consistent with their
investment objective and policies, each of Prime Obligations Fund, Money Market
Fund and Plus Fund may invest up to 5% of their net assets in these and other
types of asset-backed securities that may be developed in the future.  However,
Prime Obligations Fund, Money Market Fund and Plus Fund will generally not
invest in an asset-backed security if the income received with respect to such
investment constitutes rental income or other income not treated as qualifying
income under the 90% test described in "Tax Information" below.  In general, the
collateral supporting these securities is of shorter maturity than mortgage
loans and is less likely to experience substantial prepayments in response to
interest rate fluctuations.

Prime Obligations Fund, Money Market Fund and Plus Fund may invest in new types
of asset-backed securities that may be developed in the future to the extent
consistent with their investment objective and policies.  This Statement of
Additional Information will be amended or supplemented as necessary to reflect
Prime Obligations, Money Market or Plus Funds' intention to invest in asset-
backed securities with characteristics that are materially different from the
securities described in the preceding paragraph.     

As set forth above, several types of asset-backed and receivables-backed
securities have already been offered to investors, including, for example,
Certificates for Automobile Receivables/sm/ ("CARS/sm/") and interests in pools
of credit card receivables.  CARS/sm/ represent undivided fractional interests
in a trust ("CAR Trust") whose assets consist of a pool of motor vehicle retail
installment sales contracts and security interests in the vehicles securing the
contracts.  Payments of principal and interest on CARS/sm/ are passed through
monthly to certificate holders, and are guaranteed up to certain amounts and for
a certain time period by a letter of credit issued by a financial institution
unaffiliated with the trustee or originator of the CAR Trust.  An investor's
return on CARS/sm/ may be affected by early prepayment of principal on the
underlying vehicle sales contracts.  If the letter of credit is exhausted, the
CAR Trust may be prevented from realizing the full amount due on a sales
contract because of state law requirements and restrictions relating to
foreclosure sales of vehicles and the obtaining of deficiency judgments
following such sales or because of depreciation, damage or loss of a vehicle,
the application of federal and state bankruptcy and insolvency laws, or other
factors.  As a result, certificate


                                       5
<PAGE>
 
holders may experience delays in payments or losses if the letter of credit is
exhausted.

Asset-backed securities present certain risks that are not presented by
mortgage-backed securities.  Primarily, these securities may not have the
benefit of any security interest in the related assets.  Credit card receivables
are generally unsecured and the debtors are entitled to the protection of a
number of state and federal consumer credit laws, many of which give such
debtors the right to set off certain amounts owed on the credit cards, thereby
reducing the balance due.  There is the possibility that recoveries on
repossessed collateral may not, in some cases, be available to support payments
on these securities.

Asset-backed securities are often backed by a pool of assets representing the
obligations of a number of different parties.  To lessen the effect of failures
by obligors on underlying assets to make payments, the securities may contain
elements of credit support which fall into two categories:  (i) liquidity
protection and (ii) protection against losses resulting from ultimate default by
an obligor or servicer.  Liquidity protection refers to the provision of
advances, generally by the entity administering the pool of assets, to ensure
that the receipt of payments on the losses results from payment of the insurance
obligations on at least a portion of the assets in the pool.  This protection
may be provided through guarantees, policies or letters of credit obtained by
the issuer or sponsor from third parties, through various means of structuring
the transactions or through a combination of such approaches.  The degree of
credit support provided for each issue is generally based on historical
information reflecting the level of credit risk associated with the underlying
assets.  Delinquency or loss in excess of that anticipated or failure of the
credit support could adversely affect the value of or return on an investment in
such a security.

The availability of asset-backed securities may be affected by legislative or
regulatory developments.  It is possible that such developments could require
Money Market Fund or Plus Fund to dispose of any of their respective then
existing holdings of such securities.

FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES
- ----------------------------------------------

Each Fund may purchase securities on a when-issued basis or purchase or sell
securities on a forward commitment basis.  These transactions involve a
commitment by the Fund to purchase or sell securities at a future date.  The
price of the underlying securities (usually expressed in terms of yield) and the
date when the securities will be delivered and paid for (the settlement date)
are fixed at the time the transaction is negotiated.  When-issued purchases and
forward commitment transactions are negotiated

                                       6
<PAGE>
 
directly with the other party, and such commitments are not traded on exchanges,
but may be traded over-the-counter.

A Fund will purchase securities on a when-issued basis or purchase or sell
securities on a forward commitment basis only with the intention of completing
the transaction and actually purchasing or selling the securities.  If deemed
advisable as a matter of investment strategy, however, a Fund may dispose of or
renegotiate a commitment after entering into it.  A Fund also may sell
securities it has committed to purchase before those securities are delivered to
the Fund on the settlement date.  The Fund may realize a capital gain or loss in
connection with these transactions. For purposes of determining the Fund's
average dollar weighted maturity, the maturity of when-issued or forward
commitment securities will be calculated from the commitment date.

When a Fund purchases securities on a when-issued or forward commitment basis,
the Fund's custodian or subcustodian will maintain in a segregated account cash
or liquid high quality debt securities having a value (determined daily) at
least equal to the amount of the Fund's purchase commitments.  In the case of a
forward commitment to sell portfolio securities subject to such commitment, the
custodian or subcustodian will hold the portfolio securities in a segregated
account while the commitment is outstanding.  These procedures are designed to
ensure that the Fund will maintain sufficient assets at all times to cover its
obligations under when-issued purchases and forward commitments.

VARIABLE AMOUNT MASTER DEMAND NOTES
- -----------------------------------

Each Fund (other than Treasury Obligations Fund) may purchase variable amount
master demand notes.  These obligations permit the investment of fluctuating
amounts at varying rates of interest pursuant to direct arrangements between a
Fund, as lender, and the borrower.  Variable amount master demand notes are
direct lending arrangements between the lender and borrower and are not
generally transferable nor are they ordinarily rated.  A Fund may invest in them
only if the Adviser believes that the notes are of comparable quality to the
other obligations in which the Fund may invest.

VARIABLE RATE AND FLOATING RATE DEMAND INSTRUMENTS
- --------------------------------------------------

Each Fund (other than Treasury Obligations Fund) may purchase variable and
floating rate demand instruments that are tax exempt municipal obligations or
other debt securities that possess a floating or variable interest rate
adjustment formula.  These instruments permit a Fund to demand payment of the
principal balance plus unpaid accrued interest upon a specified number of days'
notice to the issuer or its agent.  The demand feature may be backed by a bank
letter of credit or guarantee issued with respect to such instrument.


                                       7
<PAGE>
 
  The terms of the variable or floating rate demand instruments that a Fund may
purchase provide that interest rates are adjustable at intervals ranging from
daily up to six months, and the adjustments are based upon current market
levels, the prime rate of a bank or other appropriate interest rate adjustment
index as provided in the respective instruments.  Some of these instruments are
payable on demand on a daily basis or on not more than seven days' notice.
Others, such as instruments with quarterly or semiannual interest rate
adjustments, may be put back to the issuer on designated days on not more than
thirty days' notice.  Still others are automatically called by the issuer unless
a Fund instructs otherwise.  The Trust, on behalf of a Fund, intends to exercise
the demand only (1) upon a default under the terms of the debt security, (2) as
needed to provide liquidity to a Fund, (3) to maintain the respective quality
standards of a Fund's investment portfolio, or (4) to attain a more optimal
portfolio structure.  A Fund will determine the variable or floating rate demand
instruments that it will purchase in accordance with procedures approved by the
Trustees to minimize credit risks.  Accordingly, any variable or floating rate
demand instrument must satisfy a Fund's credit criteria with respect to both its
long-term and short-term ratings, except that where credit support is provided,
a Fund may rely solely upon the short-term rating of the variable or floating
rate demand instrument, i.e., the right to sell.  To be eligible for purchase of
a Fund,  a variable or floating rate demand instrument which is unrated must
have quality characteristics similar to those of other obligations in which the
Fund may invest.  The Adviser may determine that an unrated variable or floating
rate demand instrument meets a Fund's quality criteria by reason of being backed
by a letter of credit or guarantee issued by a bank that meets the quality
criteria for a Fund.  Thus, either the credit of the issuer of the obligation or
the guarantor bank or both will meet the quality standards of the Fund.

The maturity of the variable or floating rate demand instruments held by a Fund
will ordinarily be deemed to be the longer of (1) the notice period required
before the Fund is entitled to receive payment of the principal amount of the
instrument or (2) the period remaining until the instrument's next interest rate
adjustment.  The acquisition of variable or floating rate demand notes for a
Fund must also meet the requirements of rules issued by the SEC applicable to
the use of the amortized cost method of securities valuation.

Each Fund (other than Treasury Obligations Fund and Government Fund) may invest
in participation interests in variable or floating rate tax-exempt obligations
held by financial institutions (usually commercial banks).  Such participation
interests provide a Fund with a specific undivided interest (up to 100%) in the
underlying obligation and the right to demand payment of its proportional
interest in the unpaid principal balance plus


                                       8
<PAGE>
 
accrued interest from the financial institution upon a specific number of days'
notice.  In addition, the participation interest generally is backed by an
irrevocable letter of credit or guarantee from the institution.  The financial
institution usually is entitled to a fee for servicing the obligation and
providing the letter of credit.

RESTRICTED AND OTHER ILLIQUID SECURITIES
- ----------------------------------------

A Fund may purchase securities that are not registered ("restricted securities")
under the Securities Act of 1933, as amended ("1933 Act"), including restricted
securities offered and sold to "qualified institutional buyers" under Rule 144A
under the 1933 Act.  However, a Fund will not invest more than 10% of the value
of its net assets in securities which are illiquid, which includes fixed time
deposits and repurchase agreements maturing in more than seven days that cannot
be traded on a secondary market and restricted securities, unless, in the case
of restricted securities, the Board of Trustees determines, based upon a
continuing review of the trading markets for the specific restricted security,
that such restricted securities are liquid.  The Board of Trustees may adopt
guidelines and delegate to the Adviser the daily function of determining and
monitoring liquidity of restricted securities.  The Board of Trustees, however,
will retain sufficient oversight and be ultimately responsible for the
determinations.  Since it is not possible to predict with assurance that the
market for securities eligible for resale under Rule 144A will continue to be
liquid, the Board of Trustees will carefully monitor each Fund's investments in
these securities, focusing on such important factors, among others, as
valuation, liquidity and availability of information.  This investment practice
could have the effect of increasing the level of illiquidity in a Fund to the
extent that qualified institutional buyers become for a time uninterested in
purchasing these restricted securities.

MUNICIPAL OBLIGATIONS
- ---------------------

Prime Obligations Fund, Plus Fund, Money Market Fund, Tax-Free Fund and
Municipal Fund may invest in municipal obligations.  Municipal obligations are
issued by or on behalf of states, territories and possessions of the United
States and their political subdivisions, agencies, authorities and
instrumentalities and the District of Columbia to obtain funds for various
public purposes.  The interest on most of these obligations is generally exempt
from regular federal income tax.  The two principal classifications of municipal
obligations are "notes" and "bonds."

Notes.   Municipal notes are generally used to provide for short-term capital
needs and generally have maturities of one year or less.  Municipal notes
include tax anticipation notes,


                                       9
<PAGE>
 
revenue anticipation notes, bond anticipation notes, tax and revenue
anticipation notes, construction loan notes, tax-exempt commercial paper and
certain receipts for municipal obligations.

Tax anticipation notes are sold to finance working capital needs of
municipalities.  They are generally payable from specific tax revenues expected
to be received at a future date.  They are  usually general obligations of the
issuer, secured by the taxing power for payment of principal and interest.
Revenue anticipation notes are issued in expectation of receipt of other types
of revenue such as federal revenues available under the Federal Revenue Sharing
Program.  Tax anticipation notes and revenue anticipation notes are generally
issued in anticipation of various seasonal revenues such as income, sales, use,
and business taxes.  Bond anticipation notes are sold to provide interim
financing in anticipation of long-term financing in the market.  In most cases,
these monies provide for the repayment of the notes. Construction loan notes are
sold to provide construction financing.  These notes are secured by mortgage
notes insured by the Federal Housing Authority; however, the proceeds from the
issuance may be less than the economic equivalent of the payment of principal
and interest on the mortgage note if there had been a default.  Tax-exempt
commercial paper consists of short-term unsecured promissory notes issued by a
state or local government or an authority or agency thereof.  The Funds which
invest in municipal obligations may also acquire securities in the form of
custodial receipts which evidence  ownership of future interest payments,
principal payments or both on certain state and local governmental and authority
obligations where, in the opinion of bond counsel, interest payments with
respect to such custodial receipts are excluded from gross income for federal
income tax purposes.  Such obligations are held in custody by a bank on behalf
of the holders of the receipts.  These custodial receipts are known by various
names, including "Municipal Receipts" ("MRs") and "Municipal Certificates of
Accrual on Tax-Exempt Securities" ("M-CATS").  There are a number of other types
of notes issued for different purposes and secured differently from those
described above.

Bonds.  Municipal bonds, which generally meet longer term capital needs and have
maturities of more than one year when issued, have two principal
classifications, "general obligation"  bonds and "revenue" bonds.

General obligation bonds are issued by entities such as states, counties,
cities, towns and regional districts and are used to fund a wide range of public
projects including the construction or improvement of schools, highways and
roads, water and sewer systems and a variety of other public purposes.  The
basic security of general obligation bonds is the issuer's pledge of its faith,
credit and taxing power for the payment of principal and interest.  The taxes
that can be levied for the payment of


                                      10
<PAGE>
 
debt service may be limited or unlimited as to rate or amount or special
assessments.

Revenue bonds have been issued to fund a wide variety of capital projects
including:  electric, gas, water and sewer systems; highways, bridges and
tunnels; port and airport facilities; colleges and universities; and hospitals.
The principal security for a revenue bond is generally the net revenues derived
from a particular facility or group of facilities or, in some cases, from the
proceeds of a special excise or other specific revenue source.  Although the
principal security behind these bonds varies widely, many provide additional
security in the form of a debt service reserve fund whose monies may also be
used to make principal and interest payments on the issuer's obligations.
Housing finance authorities have a wide range of security including partially or
fully insured, rent subsidized and/or collateralized mortgages, and/or the net
revenues from housing or other public projects.  In addition to a debt service
reserve fund, some authorities provide further security in the form of a state's
ability (without obligation) to make up deficiencies in the debt service reserve
fund.  Lease rental revenue bonds issued by a state or local authority for
capital projects are secured by annual lease rental payments from the state or
locality to the authority sufficient to cover debt service on the authority's
obligations.

Private activity bonds (a term that includes certain types of bonds, the
proceeds of which are used to a specified extent for the benefit of persons
other than governmental units), although nominally issued by municipal
authorities, are generally not secured by the taxing power of the municipality
but are secured by the revenues of the authority derived from payments by the
industrial user.  Tax-Free Fund does not intend to invest in private activity
bonds if the interest from such bonds would be an item of tax preference to
shareholders under the federal alternative minimum tax.

Municipal bonds with a series of maturity dates are called serial bonds.  The
serial bonds which the Funds may purchase are limited to short-term serial
bonds--those with original or remaining maturities of thirteen months or less.
The Funds may purchase long-term bonds provided that they have a remaining
maturity of thirteen months or less or, in the case of bonds called for
redemption, the date on which the redemption payment must be made is within
thirteen months.  The Funds may also purchase long-term bonds (sometimes
referred to as "Put Bonds"), which are subject to a Fund's commitment to put the
bond back to the issuer at par at a designated time within thirteen months and
the issuer's commitment to so purchase the bond at such price and time.

The Funds which invest in municipal obligations may invest in tender option
bonds.  A tender option bond is a municipal obliga-


                                      11
<PAGE>
 
tion (generally held pursuant to a custodial arrangement) having a relatively
long maturity and bearing interest at a fixed rate substantially higher than
prevailing short-term tax-exempt rates.  The bond is typically issued in
conjunction with the agreement of a third party, such as a bank, broker-dealer
or other financial institution, pursuant to which such institution grants the
security holders the option, at periodic intervals, to tender their securities
to the institution and receive the face value thereof.  As consideration for
providing the option, the financial institution receives periodic fees equal to
the difference between the bond's fixed coupon rate and the rate, as determined
by a remarketing or similar agent at or near the commencement of such period,
that would cause the bond, coupled with the tender option, to trade at par on
the date of such determination.  Thus, after payment of this fee, the security
holder effectively holds a demand obligation that bears interest at the
prevailing short-term tax-exempt rate.  However, an institution will not be
obligated to accept tendered bonds in the event of certain defaults by, or a
significant downgrading in the credit rating assigned to, the issuer of the
bond.

The tender option will be taken into consideration in determining the maturity
of tender option bonds and the average portfolio maturity of each Fund.  The
liquidity of a tender option bond is a function of the credit quality of both
the bond issuer and the financial institution providing liquidity.
Consequently, tender option bonds are deemed to be liquid unless, in the opinion
of the Adviser, the credit quality of the bond issuer and the financial
institution is deemed, in light of the relevant Fund's credit quality
requirements, to be inadequate.

Although Tax-Free Fund and Municipal Fund intend to invest in tender option
bonds the interest on which will, in the opinion of counsel for the issuer and
sponsor or counsel selected by the Adviser, be excluded from gross income for
federal income tax purposes, there is no assurance that the Internal Revenue
Service will agree with such counsel's opinion in any particular case.
Consequently, there is a risk that a Fund will not be considered the owner of
such tender option bonds and thus will not be entitled to treat such interest as
exempt from such tax.  A similar risk exists for certain other investments
subject to puts or similar rights.  Additionally, the federal income tax
treatment of certain other aspects of these investments, including the proper
tax treatment of tender options and the associated fees, in relation to various
regulated investment company tax provisions is unclear.  Tax-Free Fund and
Municipal Fund intend to manage their respective portfolios in a manner designed
to eliminate or minimize any adverse impact from the tax rules applicable to
these investments.

In addition to general obligation bonds, revenue bonds and serial bonds, there
are a variety of hybrid and special types of munici-


                                      12
<PAGE>
 
pal obligations as well as numerous differences in the security of municipal
obligations both within and between the two principal classifications above.

Tax-Free Fund and Municipal Fund may purchase municipal instruments that are
backed by letters of credit issued by foreign banks that have a branch, agency
or subsidiary in the United States.  Such letters of credit, like other
obligations of foreign banks, may involve credit risks in addition to those of
domestic obligations, including risks relating to future political and economic
developments, nationalization, foreign governmental restrictions such as
exchange controls and difficulties in obtaining or enforcing a judgment against
a foreign bank (including branches).

For the purpose of the Funds' investment restrictions, the identification of the
"issuer" of municipal obligations that are not general obligation bonds is made
by the Adviser on the basis of the characteristics of the obligation as
described above, the most significant of which is the source of funds for the
payment of principal of and interest on such obligations.

An entire issue of municipal obligations may be purchased by one or a small
number of institutional investors such as a Fund.  Thus, the issue may not be
said to be publicly offered.  Unlike securities which must be registered under
the 1933 Act prior to offer and sale, unless an exemption from such registration
is available, municipal obligations which are not publicly offered may
nevertheless be readily marketable.  A secondary market may exist for municipal
obligations which were not publicly offered initially.

Municipal obligations purchased for a Fund are subject to the policy on holdings
of securities which are not readily marketable contained in the Fund's
Prospectus.  The Adviser determines whether a municipal obligation is liquid
based on whether it may be sold in a reasonable time consistent with the customs
of the municipal markets (usually seven days) at a price (or interest rate)
which accurately reflects its value.  The Adviser believes that the quality
standards applicable to each Fund's investments enhance liquidity.  In addition,
standby commitments and demand obligations also enhance liquidity.

Yields on municipal obligations depend on a variety of factors, including money
market conditions, municipal bond market conditions, the size of a particular
offering, the maturity of the obligation and the quality of the issue.  High
grade municipal obligations tend to have a lower yield than lower rated
obligations.  Municipal obligations are subject to the provisions of bankruptcy,
insolvency and other laws affecting the rights and remedies of creditors, such
as the Federal Bankruptcy Code, and laws, if any, which may be enacted by
Congress or state legisla-


                                      13
<PAGE>
 
tures extending the time for payment of principal or interest, or both, or
imposing other constraints upon enforcement of such obligations or
municipalities to levy taxes.  There is also the possibility that as a result of
litigation or other conditions the power or ability of any one or more issuers
to pay when due principal of and interest on its or their municipal obligations
may be materially affected.

STANDBY COMMITMENTS
- -------------------

In order to enhance the liquidity, stability or quality of municipal
obligations, Prime Obligations Fund, Plus Fund, Money Market Fund, Tax-Free Fund
and Municipal Fund may each acquire the right to sell a security to another
party at a guaranteed price and date.  Such a right to resell may be referred to
as a put, demand feature or "standby commitment", depending on its
characteristics.  The aggregate price which a Fund pays for securities with
standby commitments may be higher than the price which otherwise would be paid
for the securities.  Standby commitments may not be available or may not be
available on satisfactory terms.

Standby commitments may involve letters of credit issued by domestic or foreign
banks supporting the other party's ability to purchase the security from the
Fund.  The right to sell may be  exercisable on demand or at specific intervals,
and may form part of a security or be acquired separately by the Fund.  In
considering whether a security meets a Fund's quality standards, the Adviser
will look to the creditworthiness of the party providing the Fund with the right
to sell as well as the quality of the security itself.

Tax-Free Fund and Municipal Fund each value municipal obligations which are
subject to standby commitments at amortized cost.  The exercise price of the
standby commitments is expected to approximate such amortized cost.  No value is
assigned to the standby commitments for purposes of determining the Fund's net
asset value.  Since the value of a standby commitment is dependent on the
ability of the standby commitment writer to meet its obligation to repurchase,
the policy of each Fund that may enter into such transactions is to enter into
such transactions only with banks, brokers or dealers which represent a minimal
risk of default.  The duration of standby commitments will not be a factor in
determining the weighted average maturity of a Fund.

Management of the Trust understands that the Internal Revenue Service has issued
a favorable revenue ruling to the effect that, under specified circumstances, a
registered investment company will be the owner of tax-exempt municipal
obligations acquired subject to a put option.  The Internal Revenue Service has
also issued private letter rulings to certain taxpayers (which do not serve as
precedent for other taxpayers, and which are applicable


                                      14
<PAGE>
 
only to the taxpayer requesting the ruling and which have, on occasion, been
reversed by the Internal Revenue Service) to the effect that they are considered
the owners of the municipal obligations subject to standby commitments so that
the interest on such instruments will be tax-exempt income to them.  The
Internal Revenue Service has subsequently announced that it will not ordinarily
issue advance letter rulings as to the identity of the true owner of property in
cases involving the sale of securities or participation interests therein if the
purchaser has the right to cause the security, or the participation interest
therein, to be purchased by either the seller or a third party.  The Tax-Free
Fund and Municipal Fund each intends to take the position that it is the owner
of any municipal obligations acquired subject to a standby commitment or
acquired or held with certain other types of put rights and that its
distribution of tax-exempt interest earned with respect to such municipal
obligations will be tax-exempt for its shareholders.  There is no assurance that
standby commitments will be available to these Funds and neither Fund has
assumed that such commitments will be available under all market conditions.


                             INVESTMENT LIMITATIONS

The following restrictions may not be changed with respect to any Fund without
the approval of the majority of outstanding voting securities of that Fund
(which, under the Investment Company Act and the rules thereunder and as used in
the Prospectus and this Statement of Additional Information, means the lesser of
(1) 67% of the shares of that Fund present at a meeting if the holders of more
than 50% of the outstanding shares of that Fund are present in person or by
proxy, or (2) more than 50% of the outstanding shares of that Fund).  Investment
restrictions that involve a maximum percentage of securities or assets shall not
be considered to be violated unless an excess over the percentage occurs
immediately after, and is caused by, an acquisition or encumbrance of securities
or assets of, or borrowings by or on behalf of, a Fund, with the exception of
borrowings permitted by Investment Restriction (3).

Accordingly, a Fund may not:

(1)  with respect to 75% of its total assets taken at market value, invest more
than 5% of the value of the total assets of that Fund in the securities of any
one issuer, except U.S. Government securities and repurchase agreements
collateralized by U.S. Government securities.  This restriction does not,
however, apply to any Fund classified as a non-diversified company under the
Investment Company Act;

(2)  with respect to 75% of its total assets taken at market value, purchase the
securities of any one issuer if, as a result


                                      15
<PAGE>
 
of such purchase, that Fund would hold more than 10% of the outstanding voting
securities of that issuer.  This restriction does not, however, apply to any
Fund classified as a non-diversified company under the Investment Company Act;

(3)  borrow money, except from banks on a temporary basis for extraordinary or
emergency purposes, provided that a Fund is required to maintain asset coverage
of 300% for all borrowings and that no purchases of securities will be made if
such borrowings exceed 5% of the value of the Fund's assets.  This restriction
does not apply to cash collateral received as a result of portfolio securities
lending;

(4)  mortgage, pledge or hypothecate its assets except to secure permitted
borrowings;

(5)  act as underwriter of the securities issued by others, except to the extent
that the purchase of securities in accordance with a Fund's investment objective
and policies directly from the issuer thereof and the later disposition thereof
may be deemed to be underwriting;

(6)  purchase securities if such purchase would cause more than 25% in the
aggregate of the market value of the total assets of a Fund to be invested in
the securities of one or more issuers having their principal business activities
in the same industry, provided that there is no limitation with respect to, and
each Fund reserves freedom of action, when otherwise consistent with its
investment policies to, concentrate its investments in, U.S. Government
securities, obligations (other than commercial paper) issued or guaranteed by
U.S. banks, and U.S. branches of foreign banks and repurchase agreements and
securities loans collateralized by U.S. Government securities or such bank
obligations, in the case of the Funds other than the Money Market Fund and Plus
Fund, and obligations (other than commercial paper) issued by U.S. banks and
U.S. branches of U.S. or foreign banks and repurchase agreements and securities
loans collateralized by U.S. Government securities or such bank obligations, in
the case of the Money Market Fund and Plus Fund.  (For the purposes of this
restriction, state and municipal governments and their agencies and authorities
are not deemed to be industries, and telephone companies are considered to be a
separate industry from water, gas or electric utilities, personal credit finance
companies and business credit finance companies are deemed to be separate
industries and wholly-owned finance companies are considered to be in the
industry of their parents if their activities are primarily related to financing
the activities of their parents.  Such concentration may be effected when the
Adviser determines that risk adjusted returns in such industries are considered
favorable relative to other industries.)  Notwithstanding the foregoing, each of
Money Market Fund and Plus Fund will invest more than 25% of the value of its
total assets in bank obliga-


                                      16
<PAGE>
 
tions (whether foreign or domestic) except that if adverse economic conditions
prevail in the banking industry each of Money Market Fund and Plus Fund Fund
may, for defensive purposes, temporarily invest less than 25% of the value of
its total assets in bank obligations;

(7)  issue senior securities, except as appropriate to evidence indebtedness
that a Fund is permitted to incur and except for shares of existing or
additional series of the Trust;

(8)  purchase or sell real estate (excluding securities secured by real estate
or interests therein), interests in oil, gas or mineral leases, commodities or
commodities contracts.  The Trust reserves the freedom to hold and to sell real
estate acquired for any Fund as a result of the ownership of securities;

(9)  make loans to other persons, except loans of portfolio securities and
except to the extent that the purchase of debt obligations and entry into
repurchase agreements in accordance with such Fund's investment objective and
policies may be deemed to be loans;

(10) purchase securities on margin (except for delayed delivery or when-issued
transactions or such short-term credits as are necessary for the clearance of
transactions), make short sales of securities, maintain a short position, or
invest in or write puts, calls or combinations thereof (except that a Fund may
acquire puts in connection with the acquisition of a debt instrument);

(11) invest in other companies for the purpose of exercising control or
management.

In addition to the fundamental policies mentioned above, the Board of Trustees
of the Trust has adopted the following non-fundamental policy which may be
changed or amended by action of the Board of Trustees without approval of
shareholders.  Accordingly, the Trust may not, on behalf of any Fund, invest in
repurchase agreements maturing in more than seven days and securities which are
not readily marketable if, as a result thereof, more than 10% of the net assets
of a Fund (taken at market value) would be invested in such investments.

The staff of the SEC has taken the position that fixed time deposits maturing in
more than seven days that cannot be traded on a secondary market are illiquid
and not readily marketable.  Until such time (if any) as this position changes,
the Trust, on behalf of the Funds, will include such investments in the 10%
limit on unmarketable securities.  Restricted securities (including commercial
paper issued pursuant to Section 4(2) of the 1933 Act) which the Board of
Trustees has determined are liquid will


                                      17
<PAGE>
 
not be deemed to be unmarketable for purposes of this restriction.

Pursuant to SEC Rule 2a-7, a Fund (other than Tax-Free Fund and Municipal Fund)
may not invest more than 5% of its total assets in the securities of any one
issuer (except U.S. Government securities or repurchase agreements
collateralized by such securities).  A Fund may, however, invest more than 5% of
its total assets in the First Tier Securities of a single issuer for a period of
up to three business days after the purchase thereof, although such Fund may not
make more than one such investment at any time.  Each Fund, other than the Tax-
Free Fund and Municipal Fund, may only purchase "First Tier Securities" as
defined below.  Securities which are rated in the highest short-term rating
category by at least two Nationally Recognized Statistical Rating Organizations
("NRSROs") are "First Tier Securities".  Securities rated in the top two short-
term rating categories by at least two NRSROs, or if only the NRSRO has assigned
a rating, by that NRSRO, but which are not First Tier Securities, are "Second
Tier Securities".  Pursuant to SEC Rule 2a-7 the foregoing operating policies
are not applicable to Tax-Free Fund and Municipal Fund.  Immediately after the
acquisition of any put by a Fund (other than Tax-Free Fund and Municipal Fund),
not more than 5% of such Fund's total assets may be invested in securities
issued by or subject to puts from the same issuer.  However, this limitation
will not apply to the issuer of unconditional puts if the Fund does not have
more than 10% of its total assets invested in securities issued by or subject to
unconditional puts from such issuer. "NRSROs" include Standard & Poor's Ratings
Group, Moody's Investors Service, Inc., Duff & Phelps, Inc., Fitch Investors
Service, Inc., IBCA Limited and its affiliate IBCA Inc., and Thomson BankWatch,
Inc.  For a description of their rating categories, see Appendix A.

Pursuant to SEC Rule 2a-7, immediately after the acquisition of any put by Tax-
Free Fund and Municipal Fund, not more than 5% of the Fund's total assets may be
invested in securities issued by or subject to puts from the same issuer.
However, this limitation applies only with respect to 75% of each such Fund's
total assets.  In addition, this limitation will not apply to the issuer of
unconditional puts if the Fund does not have more than 10% of its total assets
invested in securities issued by or subject to unconditional puts from such
issuer.  Tax-Free and Municipal Fund each will operate in accordance with this
operating policy which complies with SEC Rule 2a-7.

"Value" for the purposes of all investment restrictions shall mean the value
used in determining a Fund's net asset value.  "U.S. Government securities"
shall mean securities issued or guaranteed by the U.S. Government or any of its
agencies, authorities or instrumentalities.

THE ADVISER, ADMINISTRATOR, DISTRIBUTOR AND TRANSFER AGENT

THE ADVISER AND ADMINISTRATOR
- -----------------------------

GSAM, a separate operating division of Goldman Sachs, acts as the investment
adviser and administrator of each Fund. As such, GSAM is responsible for the
management of each Fund's assets in accordance with such Fund's investment
objective and policies.

Under each of the separate Investment Advisory Agreements between GSAM and the
Trust on behalf of each Fund, GSAM, subject to the supervision of the Board of
Trustees and in conformity with the stated policies of each Fund, manages the
Fund's portfolio and directs the investments of the Fund. For these services,
GSAM is entitled to a monthly fee at an annual rate equal to .075% of each
Fund's average daily net assets. As of December 31, 1994, the Trust's fiscal
year end, Municipal Fund had not commenced operations. Plus Fund was not
organized until October, 1995.

Each Fund is responsible for all of its expenses other than those expressly
borne by GSAM under the Investment Advisory Agreement. The expenses borne by
shares of each Fund include the Fund's investment advisory fee, account
administration fees, expenses of issuing reports to shareholders, custodian
fees, taxes, its proportionate share of legal fees, SEC insurance fees, blue sky
fees, auditing and tax return preparation fees, taxes, Trustees' fees, insurance
expenses and trade association dues. In the event that the expenses of a Fund
(including the fees payable to GSAM, but excluding interest, taxes, brokerage
commissions, litigation and indemnification expenses and other extraordinary
expenses) for any fiscal year exceed the limits set by certain state securities
administrators, GSAM will reduce its fee payable on behalf of that Fund by the
amount of such excess but only to the extent of the Fund's fee. Repayment of any
excess amounts will be made on a monthly basis. The most restrictive expense
limitation currently applicable to each Fund is 2.5% of the first $30 million of
the Fund's average annual net assets, 2.0% of the next $70 million of such
assets, and 1.5% of such assets in excess of $100 million.

For the period ended December 31, 1994, and the fiscal years ended January 31,
1994 and January 31, 1993 the amount of the advisory fee incurred by each Fund
then in existence was as follows:

GSAM has agreed that it will not impose a portion of its advisory fees referred
to above, pursuant to applicable contracts. Had such fees been imposed during
the eleven month period ended December 31, 1994 with respect to Prime
Obligations Fund, Treasury Obligations Fund, and Government Fund, advisory fees
of $1,609,383, $554,447 and $128,944, respectively, would have been incurred by
these Funds during such period. Had the advisory fee been imposed during the
period from May 18, 1994 (commencement of operations) and July 19, 1994
(commencement of operations) through December 31, 1994, for Money Market Fund
and Tax-Free Fund, respectively, advisory fees of $482,154 and $53,176,
respectively, would have been incurred by these Funds during such periods.

Had the advisory fee been imposed during the eleven months ended January 31,
1994 with respect to the Prime Obligations Fund and Treasury Obligations Fund
and during the period from April 6, 1993 (commencement of operations) to January
31, 1994 for the Government Fund, advisory fees of $561,534, $1,016,441 and
$21,401, respectively, would have been incurred by these Funds during such
periods.

Had the advisory fee been imposed during the fiscal year ended January 31, 1993
with respect to the Prime Obligations Fund and Treasury Obligations Fund, fees
of $746,670 and $521,085, respectively, would have been incurred by these Funds
during such period.

The Investment Advisory Agreement for each Fund, other than Plus Fund, was most
recently approved by the Board of Trustees, including the "non-interested"
Trustees, on April 26, 1995. The Investment Advisory Agreement for Plus Fund was
initially approved by the Board of Trustees, including the "non-interested"
Trustees, on October 24, 1995. Each Investment Advisory Agreement will remain in
effect until June 30, 1996 (June 30, 1997 in the case of Plus Fund) and will
continue in effect thereafter only if such continuance is specifically approved
at least annually by a majority of the Board of Trustees or by a vote of a
majority of the outstanding voting securities of each Fund (as defined in the
Investment Company Act) and, in either case, by a majority of "non-interested"
Trustees.

In connection with the foregoing services, GSAM bears the following expenses:
(a) the salaries and expenses of all personnel of




                                      25
<PAGE>
 
the Trust, except the fees and expenses of "non-interested" Trustees; and (b)
office rent and the expenses of providing investment advisory, research and
statistical facilities and related clerical expenses. Goldman Sachs has
authorized any of its directors, partners, officers and employees who have been
elected or appointed as a Trustee or officer of the Trust to serve in the
capacities in which he or she has been elected or appointed.

Except for the expenses to be paid by GSAM as indicated above, the Trust, on
behalf of each Fund, is responsible under the Investment Advisory Agreements for
the payment of all other expenses related to each Fund's operations. The
expenses borne by each Fund include: (a) the fees payable to GSAM, (b) the
Fund's allocable share of fees and expenses of "non-interested" Trustees, (c)
the fees and expenses of the Funds' custodian, including the cost of pricing the
shares of the Fund, (d) the charges and expenses of the Funds' legal counsel and
independent accountants, (e) brokers' commissions and any issue or transfer
taxes chargeable to the Trust, on behalf of each Fund, in connection with its
securities transactions, (f) the fees of any trade association of which the Fund
is a member or, in the event the Trust is a member, the Fund's proportionate
share of such fees, (g) the cost of share certificates, if any, (h) the Fund's
allocable share of the organizational expenses of the Trust and the fees and
expenses involved in registering and maintaining registration of the Trust and
of its shares with the SEC and registering the Trust as a broker or dealer and
qualifying its shares under state securities laws, including the preparation and
printing of the Trust's registration statements and prospectuses for such
purposes, (i) the Fund's allocable share of communication expenses with respect
to investor services and all expenses of shareholders' and Trustees' meetings
and preparing, printing and mailing prospectuses and reports to shareholders,
(j) litigation and indemnification expenses and other extraordinary expenses not
incurred in the ordinary course of the Fund's business, and (k) all taxes and
business fees payable by the Fund to federal, state or other governmental
agencies. Fees and expenses of legal counsel, registering shares, holding
meetings and communicating with shareholders include an allocable portion of
the cost of maintaining an internal legal and compliance department. Each Fund
will also bear an allocable portion of GSAM's costs of performing certain
accounting services not being provided by the Funds' custodian.

For the fiscal period from January 31, 1994 to December 31, 1994 (with respect
to (1) Money Market Fund the period from May 18, 1994 (commencement of
operations) to December 31, 1994 and (2) Tax-Free Fund the period from July 19,
1994 (commencement of operations) to December 31, 1994), GSAM assumed certain
expenses related to the operations of the Funds because such expenses would have
caused the Funds' total expenses to exceed certain voluntary expense
limitations. Had these expenses not been



                                      26
<PAGE>
 
assumed, an additional $415,540, $458,254, $237,091, 62,967, and $66,782 in
expenses would have been incurred by Prime Obligations Fund, Money Market Fund,
Treasury Obligations Fund, Government Fund and Tax-Free Fund, respectively, for
the relevant periods.

For the period from April 6, 1993 (commencement of operations) to January 31,
1994, GSAM assumed certain expenses related to the operations of Government Fund
because such expenses would have caused the Fund's total expenses, on an
annualized basis, to exceed certain voluntary expense limitations with respect
to such Fund. Had these expenses not been assumed, an additional $98,125 in
expenses would have been incurred by the Fund for such period. No expenses were
assumed by GSAM for the eleven month period ended January 31, 1994 for Prime
Obligations Fund or Treasury Obligations Fund.

For the fiscal year ended January 31, 1993, GSAM assumed certain expenses
related to the operations of Treasury Obligations Fund because such expenses
would have caused the Fund's total expenses to exceed certain voluntary expense
limitations. Had these expenses not been assumed, an additional $68,636 in
expenses would have been incurred by the Fund during such period. No expenses
for Prime Obligations Fund were assumed by GSAM for the fiscal year ended
January 31, 1993.

The Investment Advisory Agreements provide that GSAM shall not be liable to a
Fund for any error of judgment by GSAM or for any loss sustained by the Fund
except in the case of GSAM's willful misfeasance, bad faith, gross negligence or
reckless disregard of duty. Each Fund may use any name derived from the name
"Goldman Sachs" only as long as its Investment Advisory Agreement remains in
effect. Each Investment Advisory Agreement also provides that it shall terminate
automatically if assigned and that it may be terminated without penalty by vote
of a majority of the outstanding voting securities of the Fund or by either
party upon sixty (60) days' written notice.

Under the Trust's Administration Agreement with GSAM, GSAM administers each
Fund's business affairs subject to the supervision of the Board of Trustees and,
in connection therewith, furnishes each Fund with office facilities, bears all
fees and costs of the services furnished by the transfer agent to the Fund and
is responsible for ordinary clerical, recordkeeping and bookkeeping functions,
to the extent not provided pursuant to the Funds' custodian and advisory
agreements; preparation and filing of documents required to comply with federal
and state securities laws; supervising the activities of the Funds' custodian
and transfer agent; providing assistance in connection with meetings of the
Board of Trustees and shareholders; and other administrative services necessary
to conduct the Trust's business. GSAM will receive account administration fees
from the Fund as  described in the Prospectus.

THE DISTRIBUTOR AND TRANSFER AGENT
- ----------------------------------

Goldman Sachs serves as the distributor of shares of each Fund pursuant to a
Distribution Agreement with the Trust which was most recently approved by the
Board of Trustees on April 26, 1995. Goldman Sachs also serves as the transfer
agent of each Fund. Goldman Sachs provides customary transfer agency services to
the record holders of the Funds, including the handling of shareholder
communications, the processing of shareholder transactions, the maintenance of
shareholder account records, payment of dividends and distributions and related
functions.
    
Goldman Sachs is one of the largest international investment banking and
brokerage firms in the United States. Founded in 1869, Goldman Sachs is a leader
in financing and investing services both in the United States and abroad. As of
November 25, 1995, Goldman Sachs and its consolidated subsidiaries had assets of
approximately $____ billion and partners, capital of $1.9 billion. Goldman Sachs
became registered as an investment adviser in 1981. As of January 31, 1996
Goldman Sachs, together with its affiliates, acted as investment adviser,
administrator or distributor for approximately $57 billion in total assets.

                             PORTFOLIO TRANSACTIONS

GSAM places the portfolio transactions of the Funds and of all other accounts
managed by GSAM for execution with many firms. GSAM uses its best efforts to
obtain execution of portfolio transactions at prices which are advantageous to
each Fund and at reasonably competitive spreads or (when a disclosed commission
is being charged) at reasonably competitive commission rates. In seeking such
execution, GSAM will use its best judgment in evaluating the terms of a
transaction, and will give consideration to various relevant factors, including
without limitation the size and type of the transaction, the nature and
character of the market for the security, the confidentiality, speed and
certainty of effective execution required for the transaction, the general
execution and operational capabilities of the broker-dealer, the general
execution and operational capabilities of the firm, the reputation, reliability,
experience and financial condition of the firm, the value and quality of the
services rendered by the firm in this and other transactions, and the
reasonableness of the spread or commission, if any. Securities purchased and
sold by the Funds are generally traded in the over-the-counter market on a net
basis (i.e., without commission) through broker-dealers and banks acting for
their own account rather than as brokers, or otherwise involve transactions
directly with the issuer of such securities.

Goldman Sachs is active as an investor, dealer and/or underwriter in many types
of municipal and money market instruments. Its activities in this regard could
have some effect on the markets for those instruments which the Funds buy, hold
or sell. An order has been granted by the SEC under the Investment Company Act
which permits the Funds to deal with Goldman Sachs in transactions in certain
taxable securities in which Goldman Sachs acts as principal. As a result, the
Funds may trade with Goldman Sachs as principal subject to the terms and
conditions of such exemption.

Under the Investment Company Act, the Funds are prohibited from purchasing any
instrument of which Goldman Sachs is a principal underwriter during the
existence of an underwriting or selling syndicate relating to such instrument,
absent an exemptive order (the order referred to in the preceding paragraph will
not apply to such purchases) or the adoption of and compliance with certain
procedures under such Act. The Trust has adopted procedures which establish,
among other things, certain limitations on the amount of debt securities that
may be purchased in any single offering and on the amount of the Trust's assets
that may be invested in any single offering. Accordingly, in view of Goldman
Sachs' active role in the underwriting of debt securities, a Fund's ability to
purchase debt securities in the primary market may from time to time be limited.

<PAGE>
 
In certain instances there may be securities which are suitable for a Fund's
portfolio as well as for that of another fund of the Trust or one or more of the
other clients of GSAM. Investment decisions for each Fund and for GSAM's other
clients are made with a view to achieving their respective investment
objectives. It may develop that a particular security is bought or sold for only
one client even though it might be held by, or bought or sold for, other
clients. Likewise, a particular security may be bought for one or more clients
when one or more other clients are selling that same security. Some simultaneous
transactions are inevitable when several clients receive investment advice from
the same investment adviser, particularly when the same security is suitable for
the investment objectives of more than one client. When two or more clients are
simultaneously engaged in the purchase or sale of the same security, the
securities are allocated among clients in a manner believed to be equitable to
each. It is recognized that in some cases this system could have a detrimental
effect on the price or volume of the security in a particular transaction as far
as a Fund is concerned. Each Fund believes that over time its ability to
participate in volume transactions will produce better executions for the Funds.

During the fiscal year ended December 31, 1994, the Trust acquired and sold
securities of its regular broker-dealers: Lehman Brothers, Bear Stearns, Salomon
Brothers, Inc., CS First Boston Corp., Merrill Lynch & Co., Inc., Daiwa
Securities, Morgan Stanley & Co., Inc., Morgan Guaranty Trust, Donaldson Lufkin
& Jenrette and Swiss Bank. As of December 31, 1994, each Fund held the following
amounts of securities of its regular broker/dealers as defined in Rule 10b-1
under the Investment Company Act, or their parents ($ in thousands); Prime
Obligations Fund - Lehman Brothers ($385,111), Bear Stearns ($47,000), Salomon
Brothers, Inc. ($249,100), CS First Boston Corp. ($54,050), Merrill Lynch & Co.,
Inc. ($52,453), Daiwa Securities ($175,650), Morgan Stanley & Co., Inc.
($119,159), Morgan Guaranty Trust ($40,000); Government Fund - Lehman Brothers
($37,455), Bear Stearns ($10,000), CS First Boston Corp. ($10,000), Daiwa
Securities ($ 16,450); Treasury Obligations Fund -Lehman Brothers ($214,730),
Bear Stearns ($30,000), CS First Boston Corp. ($30,000), Merrill Lynch & Co.,
Inc. ($30,000), Daiwa Securities ($98,700), Morgan Stanley & Co., Inc.
($35,000), Morgan Guaranty Trust ($30,000); and Money Market Fund - Lehman
Brothers ($ 66,500), Bear Stearns ($6,300), Salomon Brothers, Inc. ($33,390), CS
First Boston Corp. ($7,245), Merrill Lynch & Co., Inc. ($19,996), Daiwa
Securities ($60,900), Morgan Stanley & Co., Inc. ($45,000), Morgan Guaranty
Trust ($25,000).


                                NET ASSET VALUE

The net asset value per share of each Fund (except for Government Fund) is
determined by the Funds' custodian as of the close of



30
<PAGE>
 
regular trading on the New York Stock Exchange (normally 4:00 p.m. New York
time) (in the case of the Government Fund, net asset value is determined at 5:00
p.m. New York time) on each Business Day. A Business Day means any day on which
the New York Stock Exchange is open, except for days on which banks in Chicago,
Boston or New York are closed on local holidays. Such holidays include: New
Year's Day, Martin Luther King Day, Presidents' Day, Good Friday, Memorial Day,
the Fourth of July, Labor Day, Columbus Day, Veteran's Day, Thanksgiving Day and
Christmas Day.

Each Fund's portfolio securities are valued using the amortized cost method of
valuation in an effort to maintain a constant net asset value of $1.00 per
share, which the Board of Trustees has determined to be in the best interests of
each Fund and its shareholders. This method involves valuing a security at cost
on the date of acquisition and thereafter assuming a constant accretion of a
discount or amortization of a premium to maturity, regardless of the impact of
fluctuating interest rates on the market value of the instrument. While this
method provides certainty in valuation, it may result in periods during which
value, as determined by amortized cost, is higher or lower than the price a Fund
would receive if it sold the instrument. During such periods, the yield to an
investor in a Fund may differ somewhat from that obtained in a similar
investment company which uses available market quotations to value all of its
portfolio securities. During periods of declining interest rates, the quoted
yield on shares of the Funds may tend to be higher than a like computation made
by a fund with identical investments utilizing a method of valuation based upon
market prices and estimates of market prices for all of its portfolio
instruments. Thus, if the use of amortized cost by a Fund resulted in a lower
aggregate portfolio value on a particular day, a prospective investor in the
Fund would be able to obtain a somewhat higher yield if he or she purchased
shares of the Fund on that day, than would result from investment in a fund
utilizing solely market values, and existing investors in the Fund would receive
less investment income. The converse would apply in a period of rising interest
rates.

The Board of Trustees has established procedures designed to stabilize, to the
extent reasonably possible, each Fund's price per share as computed for the
purpose of sales and redemptions at $1.00. Such procedures include review of
each Fund's portfolio by the Board of Trustees, at such intervals as it deems
appropriate, to determine whether such Fund's net asset value calculated by
using available market quotations (or an appropriate substitute which reflects
market conditions) deviates from $1.00 per share based on amortized cost, as
well as review of the methods used to calculate the deviation. If such deviation
exceeds 1/2 of 1%, the Board of Trustees will promptly consider what action, if
any, will be initiated. In the event the Board of Trustees




                                      31
<PAGE>
 
determines that a deviation exists which may result in material dilution or
other unfair results to investors or existing shareholders, it will take such
corrective action as it regards to be necessary and appropriate, including the
sale of portfolio instruments prior to maturity to realize capital gains or
losses or to shorten average portfolio maturity; withholding part or all of
dividends or payment of distributions from capital or capital gains; redemptions
of shares in kind; or establishing a net asset value per share by using
available market quotations or equivalents. In addition, in order to stabilize
the net asset value per share at $1.00 the Board of Trustees has the authority
(1) to reduce or increase the number of shares outstanding on a pro rata basis,
and (2) to offset each shareholder's pro rata portion of the deviation between
the net asset value per share and $1.00 from the shareholder's accrued dividend
account or from future dividends. Each Fund may hold cash for the purpose of
stabilizing its net asset value per share. Holdings of cash, on which no return
is earned, would tend to lower the yield on such Fund's shares.

In order to continue to use the amortized cost method of valuation each Fund's
investments, including repurchase agreements, must be U.S. dollar-denominated
instruments which the Board of Trustees determines present minimal credit risks
and which are at the time of acquisition rated by the requisite number of NRSROs
in one of the two highest short-term rating categories or, in the case of any
instrument that is not so rated, of comparable quality as determined by GSAM
and confirmed by the Board of Trustees. Also, each Fund must maintain a dollar-
weighted average portfolio maturity (not more than ninety (90) days)
appropriate to its objective of maintaining a stable net asset value of $1.00
per share and may not purchase any instrument with a remaining maturity of more
than thirteen (13) months. However, a Fund may also, consistent with the
provisions of the above-mentioned rule, invest in securities with a stated
maturity of more than thirteen (13) months, if (i) the security is a floating
or variable rate security with certain demand and interest rate reset features
and (ii) the security, except in the case of Tax-Free Fund and Municipal Fund,
is a First Tier Security.

The proceeds received by each Fund for each issue or sale of its shares, and all
net investment income, realized and unrealized gain and proceeds thereof,
subject only to the rights of creditors, will be specifically allocated to such
Fund and constitute the underlying assets of that Fund. The underlying assets of
each Fund will be segregated on the books of account, and will be charged with
the liabilities in respect to that Fund and with a share of the general
liabilities of the Trust. Expenses are allocated in proportion to the net asset
values of the respective Funds except where allocations of direct expenses can
otherwise be fairly made. In addition, within each Fund, FST Shares, FST



                                      32
<PAGE>
 
Administration Shares, FST Service Shares and FST Preferred Shares (if any) will
be subject to different expense structures (see "Organization and
Capitalization").


                                  REDEMPTIONS

The Trust may suspend the right of redemption of shares of a Fund and may
postpone payment for any period: (i) during which the New York Stock Exchange is
closed for regular trading other than customary weekend and holiday closings or
during which trading on the New York Stock Exchange is restricted, (ii) when the
SEC determines that a state of emergency exists which may make payment or
transfer not reasonably practicable, (iii) as the SEC may by order permit for
the protection of the shareholders of the Trust or (iv) at any other time when
the Trust may, under applicable laws and regulations, suspend payment on the
redemption of the Fund's shares.

The Trust agrees to redeem shares of each Fund solely in cash up to the lesser
of $250,000 or 1% of the net asset value of the Fund during any 90-day period
for any one shareholder. The Trust reserves the right to pay other redemptions,
either total or partial, by a distribution in kind of securities (instead of
cash) from a Fund's portfolio. The securities distributed in such a distribution
would be valued at the same value as that assigned to them in calculating the
net asset value of the shares being redeemed. If a shareholder receives a
distribution in kind, he or she should expect to incur transaction costs when he
or she converts the securities to cash.


                        CALCULATION OF YIELD QUOTATIONS

Each Fund's yield quotations are calculated in accordance with a standard method
prescribed by the rules of the SEC. Under this method, the yield quotation is
based on a hypothetical account having a balance of exactly one share at the
beginning of a seven-day period.

Yield, effective yield and tax equivalent yield are calculated separately for
FST Shares, FST Administration Shares, FST Service Shares and FST Preferred
Shares (if any). Each type of Share is subject to different fees and expenses
and, consequently, may have differing yields for the same period.

The yield quotation is computed as follows: the net change, exclusive of capital
changes (i.e., realized gains and losses from the sale of securities and
unrealized appreciation and depreciation), in the value of a hypothetical pre-
existing account having a balance of one share at the beginning of the base
period is determined by dividing the net change in value by


                                      33
<PAGE>
 
the value of the account at the beginning of the base period. This base period
return is then multiplied by 365/7 (366/7 in the event of a leap year) with the
resulting yield figure carried to the nearest 100th of 1%. Such yield quotation
shall take into account all fees that are charged to a Fund.

Each Fund also may advertise a quotation of effective yield for a seven (7)
calendar day period. Effective yield is computed by compounding the unannualized
base period return determined as in the preceding paragraph by adding one (1) to
that return, raising the sum to the 365/7 power (366/7 in the event of a leap
year) and subtracting one from the result, according to the following formula:

            Effective Yield=[(base period return + 1) (365/7)] - 1.

Tax-Free Fund and Municipal Fund may each also advertise a tax-equivalent yield
which is computed by dividing that portion of a Fund's yield (as computed above)
which is tax-exempt by one minus a stated income tax rate and adding the
quotient to that portion, if any, of the yield of the Fund that is not tax-
exempt.

Unlike bank deposits or other investments which pay a fixed yield or return for
a stated period of time, the return for a Fund will fluctuate from time to time
and does not provide a basis for determining future returns. Return is a
function of portfolio quality, composition, maturity and market conditions as
well as the expenses allocated to a Fund. The return of each Fund may not be
comparable to other investment alternatives because of differences in the
foregoing variables and differences in the methods used to value portfolio
securities, compute expenses and calculate return.

  The yield, effective yield and tax-equivalent yield of each Fund, except for
the Municipal Fund (which has not commenced operations) and Plus Fund (which was
organized in October, 1995) with respect to FST Shares, FST Administration
Shares and FST Service Shares for the seven-day period ended June 30, 1995 were

                                TAX INFORMATION

Each Fund has qualified and has elected or intends to qualify and elect to be
treated as a regulated investment company under Subchapter M of the Internal
Revenue Code of 1986, as amended (the "Code"). Such qualification does not
involve supervision of management or investment practices or policies by any
governmental agency or bureau.

In order to qualify as a regulated investment company, each Fund must, among
other things, (a) derive at least 90% of its annual gross income from dividends,
interest, payments with respect to securities loans and gains from the sale or
other disposition of stock or securities or certain other investments (the "90%
test"); (b) derive less than 30% of its annual gross income from the sale or
other disposition of stock, securities or certain other investments held less
than three months; and (c) diversify its holdings so that, at the end of each
quarter of its taxable year, (i) at least 50% of the market value of the Fund's
total (gross) assets is represented by cash and cash items (including
receivables), U.S. Government securities, securities of other regulated
investment companies and other securities limited, in respect of any one issuer,
to an amount not greater in value than 5% of the value of the Fund's total
assets and 10% of the outstanding voting securities of such issuer, and (ii) not
more than 25% of the value of the Fund's total assets is invested in the
securities (other than U.S. Government securities and securities of other
regulated investment companies) of any one issuer or two or more issuers
controlled by the Fund and engaged in the same, similar or related trades or
businesses. For purposes of these


                                      36
<PAGE>
 
requirements, participation interests will be treated as securities, and the
issuer will be identified on the basis of the market risk and credit risk
associated with any particular interest. Certain payments received with respect
to such interests, such as commitment fees and certain facility fees, may not be
treated as income qualifying under the 90% test.

Each Fund, as a regulated investment company, will not be subject to federal
income tax on any of its net investment income and net realized capital gains
that are distributed to shareholders with respect to any taxable year, provided
that the Fund distributes at least 90% of its investment company taxable income
(generally all of its net taxable income other than "net capital gain," which is
the excess of net long-term capital gain over net short-term capital loss) for
such year, and in the case of any Fund that earns tax-exempt interest, at least
90% of the excess of the tax-exempt interest it earns over certain disallowed
deductions. A Fund will be subject to federal income tax at regular corporate
rates on any investment company taxable income or net capital gain that it does
not distribute for a taxable year. In order to avoid a nondeductible 4% federal
excise tax, a Fund must distribute (or be deemed to have distributed) by
December 31 of each calendar year at least 98% of its taxable ordinary income
for such year, at least 98% of the excess of its capital gains over its capital
losses (generally computed on the basis of the one-year period ending on October
31 of such year), and all taxable ordinary income and the excess of capital
gains over capital losses for the previous year that were not distributed in
such year and on which the Fund paid no federal income tax.

Dividends paid by a Fund from taxable net investment income (including income
attributable to accrued market discount and a portion of the discount on certain
stripped tax-exempt obligations and their coupons) and the excess of net short-
term capital gain over net long-term capital loss will be treated as ordinary
income in the hands of shareholders. Such distributions will not qualify for the
corporate dividends-received deduction. Distributions paid by a Fund from the
excess of net long-term capital gain over net short-term capital loss are
taxable to shareholders as long-term capital gain, regardless of the length of
time the shares of a Fund have been held by such shareholders, and also will not
qualify for the corporate dividends-received deduction. A Fund's net realized
capital gains for a taxable year are computed by taking into account any
capital loss carryforward of that Fund.

Distributions paid by Tax-Free Fund or Municipal Fund from tax-exempt interest
received by it and properly designated will generally be exempt from regular
federal income tax, provided that at least 50% of the value of the Fund's total
assets at the close of each quarter of its taxable year consists of tax-exempt




                                      37
<PAGE>
 
obligations (not including shares of other regulated investment companies that
may pay exempt-interest dividends, because such shares are not treated as tax-
exempt obligations for this purpose). Distributions paid by the other Funds from
any tax-exempt interest they may receive will not be tax-exempt, because they
will not satisfy the 50% requirement described in the preceding sentence. A
portion of any tax-exempt distributions may constitute tax preference items and
may give rise to, or increase liability under, the alternative minimum tax for
particular shareholders. In addition tax-exempt distributions of a Fund may be
considered in computing the "adjusted current earnings" preference item of its
corporate shareholders in determining the corporate alternative minimum tax and
the corporate environmental tax. To the extent that a Fund invests in certain
short-term instruments, including repurchase agreements, the interest on which
is not exempt from federal income tax, any distributions of income from such
investments will be taxable to shareholders as ordinary income. All or
substantially all of any interest on indebtedness incurred directly or
indirectly to purchase or carry shares of Tax-Free Fund or Municipal Fund will
generally not be deductible. The availability of tax-exempt obligations and the
value of these Funds may be affected by restrictive tax legislation enacted in
recent years.

In purchasing municipal obligations, Tax-Free Fund and Municipal Fund each
relies on opinions of nationally-recognized bond counsel for each issue as to
the excludability of interest on such obligations from gross income for federal
income tax purposes. Each Fund does not undertake independent investigations
concerning the tax-exempt status of such obligations, nor does it guarantee or
represent that bond counsels' opinions are correct.

Distributions of net investment income and net realized capital gains will be
taxable as described above, whether received in shares or in cash. Shareholders
electing to receive distributions in the form of additional shares will have a
cost basis in each share so received equal to the amount of cash they would have
received had they elected to receive cash.

Money Market Fund and/or Plus Fund may be subject to foreign withholding or
other foreign taxes with respect to its investments in certain securities of
foreign entities. These taxes may be reduced under the terms of applicable U.S.
income tax treaties, and the applicable Fund intends to satisfy any procedural
requirements to qualify for benefits under these treaties. Although neither Fund
anticipates that more than 50% of the value of its total assets at the close of
a taxable year will be composed of securities of foreign corporations, if the
50% requirement were satisfied by either Fund, that Fund could make an election
under Code Section 853 to permit its shareholders to claim a credit or deduction
on their federal income tax returns for their pro rata portion of qualified
taxes paid by the Fund in




                                      38
<PAGE>
 
foreign countries. In the event such an election is made, shareholders will be
required to include their pro rata share of such taxes in gross income and will
be entitled to claim a foreign tax credit or deduction with respect to such
taxes, subject to certain limitations under the Code. Shareholders who are
precluded from taking such credits or deductions will nevertheless be taxed on
their pro rata share of the foreign taxes included in their gross income, unless
they are otherwise exempt from federal income tax.

Each Fund will be required to report to the Internal Revenue Service all taxable
distributions, except in the case of certain exempt shareholders. Under the
backup withholding provisions of Code Section 3406, all such distributions may
be subject to withholding of federal income tax at the rate of 31% in the case
of nonexempt shareholders who fail to furnish the Fund with their taxpayer
identification number or with certain required certifications or if the Internal
Revenue Service or a broker notifies a Fund that the number furnished by the
shareholder is incorrect or that the shareholder is subject to backup
withholding as a result of failure to report interest or dividend income.
However, any taxable distributions from Tax-Free Fund or Municipal Fund will not
be subject to backup withholding if the Fund reasonably estimates that at least
95% of its distributions will be exempt interest dividends. Each Fund may refuse
to accept an application that does not contain any required taxpayer
identification number or certification that the number provided is correct or
that the investor is an exempt recipient. If the withholding provisions are
applicable, any such distributions, whether taken in cash or reinvested in
shares, will be reduced by the amounts required to be withheld. Investors may
wish to consult their tax advisors about the applicability of the backup
withholding provisions.

All distributions (including exempt-interest dividends) whether received in
shares or cash, must be reported by each shareholder on the shareholder's
federal income tax return. The Funds will inform shareholders of the federal
income tax status of their distributions after the end of each calendar year,
including, in the case of the Tax-Free Fund and the Municipal Fund, the amounts
that qualify as exempt-interest dividends and any portions of such amounts that
constitute tax preference items under the federal alternative minimum tax.
Shareholders who received exempt-interest dividends and have not held their
shares of the applicable Fund for its entire taxable year may have designated as
tax-exempt or as a tax preference item a percentage of their distributions which
is not exactly equal to a proportionate share of the amount of tax-exempt
interest or tax preference income earned during the period of their investment
in such Fund. Each shareholder should consult his or her own tax advisor to
determine the tax consequences of an investment in the Fund in the shareholder's
own state and locality. 



                                      39
<PAGE>
 
Different tax treatment, including penalties on certain excess contributions and
deferrals, certain pre-retirement and post-retirement distributions, and certain
prohibited transactions is accorded to accounts maintained as qualified
retirement plans. Shareholders should consult their tax advisers for more
information.

Assuming that each Fund qualifies as a regulated investment company for federal
income tax purposes, each Fund, as a series of a Massachusetts business trust,
will not be subject to any income, franchise or corporate excise tax in
Massachusetts.

The foregoing discussion relates solely to U.S. federal income tax law as it
applies to U.S. persons (i.e., U.S. citizens and residents and U.S. domestic
corporations, partnerships, trusts and estates) subject to tax under such law.
The discussion does not address special tax rules applicable to certain classes
of investors, such as tax-exempt entities, insurance companies and financial
institutions. Each shareholder who is not a U.S. person should consult his or
her tax adviser regarding the U.S. and non-U.S. tax consequences of ownership of
shares of a Fund, including the possibility that such a shareholder may be
subject to a U.S. nonresident alien withholding tax at a rate of 30% (or at a
lower rate under an applicable U.S. income tax treaty) on certain distributions
from a Fund or to backup withholding on certain payments if a current IRS Form 
W-8 or acceptable substitute is not on file with the Funds.

The Funds may be subject to state or local taxes in jurisdictions in which the
Funds may be deemed to be doing business. In addition, in those states or
localities which have income tax laws, the treatment of the Trust and its
shareholders under such laws may differ from their treatment under federal
income tax laws, and investment in the Funds may have tax consequences for
shareholders different from those of a direct investment in the Funds'
securities. Shareholders should consult their own tax advisers concerning these
matters. For example, in such states or localities it may be appropriate for
shareholders to review with their tax advisers the state income and, if
applicable, intangibles tax consequences of investments by the Funds in
securities issued by the particular state or the U.S. Government or its various
agencies or instrumentalities, because many states exempt from personal income
tax distributions by regulated investment companies from interest on
obligations of the particular state or on direct U.S. Government obligations
and/or exempt from intangibles tax the value of the shares of such companies
attributable to such obligations, subject to certain state-specific
requirements and/or limitations.

This discussion of the tax treatment of the Funds and their shareholders is
based on the tax laws in effect as of the date of


                                      40

this Statement of Additional Information, which are subject to change either
prospectively or retroactively.


                        ORGANIZATION AND CAPITALIZATION


The Trust is a Massachusetts business trust established under the laws of The
Commonwealth of Massachusetts by a Declaration of Trust dated December 6, 1978.
Effective December 27, 1994, Prime Obligations Fund, Money Market Fund, Treasury
Obligations Fund, Government Fund, Tax-Free Fund and Municipal Fund were
reorganized, and each such Fund became a separate series of the Trust, a
business trust organized under the laws of the Commonwealth of Massachusetts on
December 6, 1978. Prior to the reorganization, each Fund had been a separate
series of Financial Square Trust ("FST"), which was also a Massachusetts
business trust. Except for the fact that the Funds are now series of the Trust,
shares of each Fund represent the same interest in such Fund's assets, are of
the same class, are subject to the same terms and conditions, fees and expenses
and confer the same rights as when each Fund was a series of FST. Plus Fund was
organized as a series of the Trust in October, 1995.

Each shareholder is deemed to have expressly assented and agreed to the terms of
the Declaration of Trust and is deemed to be party thereto. The authorized
capital of the Trust consists of an unlimited number of shares of beneficial
interest. The Board of Trustees has authority under the Declaration of Trust to
create and classify shares of beneficial interest in separate series or funds of
the Trust without further action by shareholders. The Declaration of Trust
further authorizes the Board of Trustees to classify or reclassify any series or
portfolio of shares into one or more classes. The Board of Trustees has
authorized the issuance of up to four classes of shares of each of the Funds:
FST Shares, FST Service Shares, FST Administration Shares and FST Preferred
Shares.

Each FST Share, FST Administration Share, FST Service Share and FST Preferred
Share of a Fund represents an equal proportionate interest in the assets
belonging to such Fund. It is contemplated that most shares will be held in the
accounts of which the record owner is a bank or other institution acting,
directly or through an agent, as nominee for its customers who are the
beneficial owners of the shares or another organization designated by such bank
or institution. FST Shares may be purchased for accounts held in the name of an
investor or institution that is not compensated by the Fund for services
provided to the institution's investors. FST Administration Shares may be
purchased for accounts held in the name of an institution that provides certain
account administration services to its customers, including maintenance of
account records and processing orders to purchase, redeem and exchange FST
Administration


                                      41
<PAGE>
 
Shares. FST Administration Shares of the Fund bear the cost of administration
fees at the annual rate of up to .25 of 1% of the average daily net assets of
such Shares. FST Service Shares may be purchased for accounts held in the name
of an institution that provides certain account administration and shareholder
liaison services to its customers, including maintenance of account records,
processing orders to purchase, redeem and exchange FST Service Shares,
responding to customer inquiries and assisting customers with investment
procedures. FST Service Shares of a Fund bear the cost of service fees at the
annual rate of up to .50 of 1% of the average daily net assets of such Shares.

It is possible that an institution or its affiliates may offer different classes
of shares to its customers and thus receive different compensation with respect
to different classes of shares of a Fund. In the event a Fund is distributed by
sales persons or any other persons, they may receive different compensation with
respect to different classes of shares of a Fund. FST Administration Shares and
FST Service Shares each have certain exclusive voting rights on matters
relating to their respective plans. Shares of each class may be exchanged only
for shares of the same class in another Fund. Except as described above, the
three classes of shares are identical. Certain aspects of the shares may be
altered, after advance notice to shareholders, if it is deemed necessary in
order to satisfy certain tax regulatory requirements.

Each FST Share, FST Service Share, FST Administration Share and FST Preferred
Share of a Fund is entitled to one vote per share; however, separate votes will
be taken by the Fund or class (or by more than one fund of the Trust or class
voting as a single class if similarly affected) on matters affecting only the
Fund or class (or those affected funds of the Trust or classes) or as otherwise
required by law. Shares are freely transferable and have no preemptive,
subscription or conversion rights. All shares issued and outstanding are fully
paid and non-assessable. The Declaration of Trust provides for shareholder
voting only for the election or removal of one or more Trustees, if a meeting is
called for that purpose, and for certain other designated matters. The Trust
does not generally hold annual or other meetings of shareholders. The shares of
the Trust have non-cumulative voting rights, which means that the holders of
more than 50% of the shares voting for the election of Trustees can elect 100%
of the Trustees if they choose to do so, and, in such event, the holders of the
remaining less than 50% of the shares voting for the election of Trustees will
not be able to elect any person or persons to the Board of Trustees. Each
Trustee serves until the next meeting of shareholders, if any, called for the
purpose of electing or reelecting such Trustee or successor to such Trustee, and
until the election and qualification of such successor, if any, or until such
Trustee sooner dies, resigns, retires or is removed by the shareholders or two-
thirds of the Trustees.

SHAREHOLDER AND TRUSTEE LIABILITY
- ---------------------------------

The Trust is an entity of the type commonly known as a "Massachusetts business
trust", which is the form in which many mutual funds are organized. Under
Massachusetts law, shareholders of such a trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
Trust. The Declaration of Trust contains an express disclaimer of shareholder
liability for acts or obligations of the Trust. Notice of such disclaimer will
normally be given in each agreement, obligation




                                      43
<PAGE>
 
or instrument entered into or executed by the Trust or the Trustees. The
Declaration of Trust provides for indemnification by the relevant fund of the
Trust (including each Fund) for any loss suffered by a shareholder as a result
of an obligation of such fund. The Declaration of Trust also provides that the
Trust shall, upon request, assume the defense of any claim made against any
shareholder for any act or obligation of the Trust and satisfy any judgment
thereon. Thus, the risk of a shareholder incurring financial loss on account of
shareholder liability is limited to circumstances in which a Fund is unable to
meet its obligations. The Trustees believes that, in view of the above, the risk
of personal liability of shareholders is not material.

The Declaration of Trust provides that the Trustees of the Trust shall not be
liable for any action taken by them in good faith, and that they shall be fully
protected in relying in good faith upon the records of the Trust and upon
reports made to the Trust by persons selected in good faith by the Trustees as
qualified to make such reports. The Declaration of Trust further provides that
the Board of Trustees will not be liable for errors of judgment or mistakes of
fact or law. The Declaration of Trust provides that the Trust will indemnify the
Trustees and officers of the Trust against liabilities and expenses reasonably
incurred in connection with litigation in which they may be involved because of
their positions with the Trust, unless it is determined in the manner provided
in the Declaration of Trust that they have not acted in good faith in the
reasonable belief that, in the case of conduct in their official capacity with
the Trust, such conduct was in the best interests of the Trust, and in all other
cases, that the conduct was at least not opposed to the best interests of the
Trust (and in the case of any criminal proceeding, they had no reasonable cause
to believe that the conduct was unlawful). However, nothing in the Declaration
of Trust or the By-Laws protects or indemnifies a Trustee or officer against any
liability to which they would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of their office.

                           CUSTODIAN AND SUBCUSTODIAN


State Street Bank and Trust Company ("State Street") has been retained to act as
custodian of the Funds' assets and, in that capacity, maintains the accounting
records and calculates the daily net asset value per share of each Fund. Its
mailing address is P.O. Box 1713, Boston, MA 02105. State Street has appointed
The Northern Trust Company, 50 South LaSalle Street, Chicago, Illinois 60675 as
subcustodian to hold cash and certain securities purchased by the Funds.

                         PREFERRED ADMINISTRATION PLAN

    
     The Trust, on behalf of the Funds, has adopted a preferred administration
plan (the "Plan") with respect to the FST Preferred Shares which authorizes the
Funds to compensate Service Organizations for providing certain account
administration services to their customers who are beneficial owners of such
shares.  Pursuant to the Plan, the Trust, on behalf of the Fund, will enter into
agreements with Service Organizations which purchase FST Preferred Shares on
behalf of their customers ("Service  Agreements").  Under such Service
Agreements the Service Organizations may: (a) act, directly or through an agent,
as the sole shareholder of record and nominee for all customers, (b) maintain
account records for each customer who beneficially owns FST Preferred Shares,
(c) process customer orders to purchase, redeem and exchange FST Preferred
Shares, and handle the transmission of funds representing the customers'
purchase price or redemption proceeds.  As compensation for such services, the
Trust, on behalf of the Funds, will pay each Service Organization a service fee
in an amount up to .10% (on an annualized  basis) of the average daily net
assets of the FST Preferred Shares of the Fund attributable to or held in the
name of such Service Organization.     

     Conflict of interest restrictions (including the Employee Retirement Income
Security Act of 1974) may apply to a Service  Organization's receipt of
compensation paid by the Trust in connection with the investment of fiduciary
funds in FST Preferred Shares.  Service Organizations, including banks regulated
by the  Comptroller of the Currency, the Federal Reserve Board or the  Federal
Deposit Insurance Corporation, and investment advisers and other money managers
subject to the jurisdiction of the SEC, the Department of Labor or state
securities commissions, are urged to consult legal advisers before investing
fiduciary assets in FST Preferred Shares.  In addition, under some state
securities laws, banks and other financial institutions purchasing FST Preferred
Shares on behalf of their customers may be required to register as dealers.

    
     The Plan was approved on ___________, 1996 by the sole shareholder of FST
Preferred Shares of the Fund.  The Board of Trustees, including a majority of
the Trustees who are not interested persons of the Trust and who have no direct
or indirect financial interest in the operation of such Plan or the related
Service Agreements, initially voted to approve the Plan and Service Agreements
at a meeting called for the purpose of voting on such Plan and Service
Agreements on April 24, 1996.  The Plan and Service Agreements will remain in
effect until April 30, 1997 and will continue in effect thereafter only if such
continuance is specifically approved annually by a vote of the Board of Trustees
in the manner described above.  The Plan may not be amended to increase
materially the amount to be spent for     



                                      47
<PAGE>

     
the services described therein without approval of the FST Preferred
Shareholders of the Funds, and all material amendments of the Plan must also be
approved by the Board of Trustees in the manner described above.  The Plan may
be terminated at any time by a majority of the Board of Trustees as described
above or by vote of a majority of the outstanding FST Preferred Shares of the
Funds.  The Service Agreements may be terminated at any time, without payment of
any penalty, by vote of a majority of the Board of Trustees as described above
or by a vote of a majority of the outstanding FST Preferred Shares of the Funds
on not more than sixty (60) days' written notice to any other party to the
Service Agreements.  The Service Agreements shall terminate automatically if
assigned.  As long as the Plan is in effect, the selection and nomination of
those Trustees who are not interested persons shall be committed to the
discretion of the Trust's Nominating Committee, which consists of all of the
non-interested members of the Board of Trustees.  The Board of Trustees has
determined that, in its judgment, there is a reasonable likelihood that the Plan
will benefit the Funds and holders of FST Preferred Shares of the Funds.  In the
Board of Trustees' quarterly review of the Plan and Service Agreements, the
Board will consider their continued appropriateness and the level of
compensation provided therein.

                                   APPENDIX A

                       DESCRIPTION OF SECURITIES RATINGS*


MOODY'S INVESTORS SERVICE,
INC.

Bond Ratings
- ------------

AAA: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

AA: Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds. They are rated lower than the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuation of protective elements
may be of greater amplitude or there may be other elements present which make
the long-term risks appear somewhat larger than with Aaa securities.

Moody's applies numerical modifiers, 1, 2, and 3 in the Aa category. The
modifier 1 indicates that the security ranks in the higher end of the Aa
category; the modifier 2 indicates a mid-range ranking; and the modifier 3
indicates that the issue ranks in the lower end of the Aa category.


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

* The ratings indicated herein are believed to be the most recent ratings
available at the date of this Statement of Additional Information for the
securities listed. Ratings are generally given to securities at the time of
issuance. While the rating agencies may from time to time revise such ratings,
they undertake no obligation to do so, and the ratings indicated do not
necessarily represent ratings which will be given to these securities on the
date of the Portfolios' taxable year end.

Short-Term Ratings

P-1: Issuers have a superior capacity for repayment of short-term promissory
obligations. Prime-1 or P-1 repayment capacity will normally be evidenced by the
following characteristics:

                                      A-1
<PAGE>
 
        .  Leading market positions in well established industries.

        .  High rates of return on funds employed.

        .  Conservative capitalization structures with moderate reliance on
           debt and ample asset protection.

        .  Broad margins in earnings coverage of fixed financial charges and
           high internal cash generation.

        .  Well established access to a range of financial markets and assured
           sources of alternate liquidity.

P-2: Issuers have a strong capacity for repayment of short-term promissory
obligations. This will normally be evidenced by many of the characteristics
cited above but to a lesser degree. Earnings trends and coverage ratios, while
sound, will be more subject to variation. Capitalization characteristics, while
still appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.

State and Municipal Obligations
- -------------------------------

Moody's ratings for state and municipal short-term obligations will be
designated Moody's Investment Grade or (MIG). Such ratings recognize the
differences between short-term credit risk and long-term risk. Factors affecting
the liquidity of the borrower and short-term cyclical elements are critical in
short-term ratings, while other factors of major importance in bond risk, long-
term secular trends for example, may be less important over the short run.
Symbols used will be as follows:

MIG 1 -- This designation denotes best quality. There is present strong
protection by established cash flows, superior liquidity support or demonstrated
broadbased access to the market for refinancing.

MIG 2 -- This designation denotes high quality. Margins of protection are ample
although not so large as in the preceding group.

A short-term rating may also be assigned on an issue having a demand feature.
Such ratings will be designated as VMIG to reflect such characteristics as
payment upon periodic demand rather than fixed maturity dates and payment
relying on external liquidity. Additionally, investors should be alert to the
fact that the source of payment may be limited to the external liquidity with no
or limited legal recourse to the issuer in the event the demand is not met VMIG-
1, and VMIG-2 ratings carry the same definitions as MIG-1, and MIG-2,
respectively.

                                      A-2
<PAGE>
 
STANDARD & POOR'S RATINGS GROUP

Bond Ratings
- ------------

AAA: Bonds rated AAA are highest grade debt obligations. This rating indicates
an extremely strong capacity to pay principal and interest.

AA: Bonds rated AA also qualify as high-quality obligations. Capacity to pay
principal and interest is very strong, and in the majority of instances they
differ from AAA issues only in small degree.

PLUS (+) OR MINUS (-): The "AA" rating may be modified by the addition of a plus
or minus sign to show relative standing within the "AA" category.

Short-Term Ratings
- ------------------

A-1: Standard & Poor's Commercial Paper ratings are current assessments of the
likelihood of timely payment of debts having an original maturity of no more
than 365 days. The A-1 designation indicates that the degree of safety regarding
timely payment is very strong. Those issues determined to possess extremely
strong safety characteristics will be denoted with a plus ( + ) sign
designation.

A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated "A-1".

Municipal Notes
- ---------------

A Standard & Poor's note rating reflects the liquidity concerns and market
access risks unique to notes. Notes due in 3 years or less will likely receive a
note rating. Notes maturing beyond 3 years will most likely receive a long-term
debt rating. The following criteria will be used in making that assessment.

        .  Amortization schedule (the larger the final maturity relative to
           other maturities the more likely it will be treated as a note).

        .  Source of payment (the more dependent the issue is on the market for
           its refinancing, the more likely it will be treated as a note).


        Note rating symbols are as follows:

                                      A-3
<PAGE>
 
SP-1 -- Very strong or strong capacity to pay principal and interest. Those
issues determined to possess overwhelming safety characteristics will be given a
plus (+) designation.

SP-2 -- Satisfactory capacity to pay principal and interest with some
vulnerability to adverse financial and economic changes over the term of the
notes.

Standard & Poor's assigns "dual" ratings to all debt issues that have a put
option or demand feature as part of their structure.

The first rating addresses the likelihood of repayment of principal and interest
as due, and the second rating addresses only the demand feature. The long-term
debt rating symbols are used for bonds to denote the long-term maturity and the
commercial paper rating symbols for the put option (for example, "AAA/A-1+").
With short-term demand debt, S&P's note rating symbols are used with the
commercial paper rating symbols (for example, "SP-1+/A-1+").

DUFF & PHELPS, INC.

Bond Ratings
- ------------

AAA: Long-term fixed income securities which are rated AAA are judged to be of
the highest credit quality. The risk factors are negligible, being only slightly
more than for risk-free U.S. Treasury debt.

AA: Long-term fixed income securities which are rated AA are judged to be of
high credit quality. Protection factors are strong. Risk is modest but may vary
slightly from time to time because of economic conditions.

Duff & Phelps applies modifiers, AA+ and AA- in the AA category for long-term
fixed securities. The modifier AA+ indicates that the security ranks in the
higher end of the AA category: the modifier AA indicates a mid-range ranking;
and the modifier AA-indicates that the issue ranks in the lower end of the AA
category.

Short-Term Ratings
- ------------------

DUFF 1: Commercial paper and certificates of deposit rated Duff 1 are considered
to have a very high certainty of timely payment. Liquidity factors are
considered excellent and are supported by strong fundamental protection factors.
Risk factors are minor.

DUFF 2: Commercial paper and certificates of deposit rated Duff 2 are considered
to have a good certainty of timely payment.

                                      A-4
<PAGE>
 
Liquidity factors and company fundamentals are considered sound. Although
ongoing internal funds needs may enlarge total financing requirements, access to
capital markets is good and risk factors are small.

Duff & Phelps applies a plus and minus rating scale, Duff 1 plus, Duff 1 and
Duff 1 minus in the Duff 1 top grade category for commercial paper and
certificates of deposit. The rating Duff 1 plus indicates that the security has
the highest certainty of timely payment, short-term liquidity is clearly
outstanding and safety is just below risk-free U.S. Treasury short-term
obligations; the rating Duff 1 indicates a very high certainty of timely
payment, liquidity factors are excellent and risk factors are minimal; and the
rating Duff 1 minus indicates a high certainty of timely payment, liquidity
factors are strong and risk factors are very small.

FITCH INVESTORS SERVICE CORP.

AAA: Bonds which are rated AAA are considered to be investment grade and of the
highest credit quality. The obligor has an exceptionally strong ability to pay
interest and repay principal, which is unlikely to be affected by reasonably
foreseeable events.

AA: Bonds which are rated AA are considered to be investment grade and of very
high credit quality. The obligor's ability to pay interest and repay principal
is very strong, although not quite as strong as bonds rated "AAA". Because bonds
rated in the "AAA" and "AA" categories are not significantly vulnerable to
foreseeable future developments, short-term debt of these issuers is generally
rated "F-1+".

Fitch applies plus (" + ") and minus (" - ") modifiers in the AA category to
indicate the relative position of a credit within the rating category. The
modifier AA+ indicates that the security ranks at the higher end of the AA
category than a security rated AA or AA- .

Eligible Fitch ratings for short-term debt obligations payable on demand or with
original maturities of up to three years, including commercial paper,
certificates of deposit, medium-term notes, and municipal and investment notes
may be rated F-1 or F-2.

F-1: Short-term debt obligations rated F-1 are considered to be of very strong
credit quality. Those issues determined to possess exceptionally strong credit
quality and having the strongest degree of assurance for timely payment will be
denoted with a plus ("+") sign designation.

                                      A-5
<PAGE>
 
F-2: Short-term debt obligations rated F-2 are considered to be of good credit
quality. Issues assigned this rating have a satisfactory degree of assurance for
timely payment, but the margin of safety is not as great as for issues assigned
"F-1+" and "F-1" ratings.

IBCA LIMITED AND IBCA INC.

A1: Short-term obligations rated A1 are supported by a very strong capacity for
timely repayment. A plus ("+") sign is added to those issues determined to
possess the highest capacity for timely payment.

A2: Short-term obligations rated A2 are supported by a strong capacity for
timely repayment, although such capacity may be susceptible to adverse changes
in business, economic or financial conditions.

THOMSON BANKWATCH, INC.

AAA: The highest category; indicates a superior ability to repay principal and
interest on a timely basis is very high.

AA:The second highest category; indicates a superior ability to repay principal
and interest on a timely basis with limited incremental risk versus issues rated
in the highest category.

Ratings in the AA Long-Term Debt category may include a plus (+) or minus (-)
designation which indicates where within the respective category the issue is
placed.

The TBW Short-Term Ratings apply only to unsecured instruments that have a
maturity of one year or less.

The TBW Short-Term Ratings specifically assess the likelihood of an untimely
payment of principal and interest.

TBW-1: The highest category; indicates a very high degree of likelihood that
principal and interest will be paid on a timely basis.

TBW-2: The second highest category; while the degree of safety regarding timely
repayment of principal and interest is strong, the relative degree of safety is
not as high as for issues rated "TBW-1".

extent consistent with the preservation of capital and the maintenance of
liquidity by investing exclusively in high quality money market instruments.
The Portfolio pursues its objective by investing in a diversified portfolio of
securities of the U.S. Government, its agencies, authorities and
instrumentalities, obligations of U.S. banks, commercial paper and other short-
term obligations of U.S. companies, states, municipalities and other entities,
and repurchase agreements.
 
  The Tax-Exempt Diversified Portfolio seeks to provide unitholders, to the ex-
tent consistent with the preservation of capital and prescribed portfolio stan-
dards, with a high level of income excluded from gross income for federal in-
come tax purposes, by investing primarily in municipal instruments. The Portfo-
lio pursues its objective by investing in a diversified portfolio of municipal
obligations issued by or on behalf of states, territories and possessions of
the United States and their political subdivisions, agencies, authorities and
instrumentalities, and the District of Columbia.

Notes:
    
*  ILA Class B Units convert to ILA Service Units seven years after purchase;
   therefore, ILA Service Unit expenses are used in the hypothetical example
   after year seven.
(1) The purpose of this table is to assist investors in understanding the
    various costs and expenses that an investment in the Portfolios will bear
    directly or indirectly. Operating expenses for the Portfolios are based on
    estimates of expenses expected to be incurred during the fiscal year ending
    December 31, 1996. The table and hypothetical example should not be
    considered a representation of past or future expenses; actual expenses may
    vary depending upon a variety of factors including the actual performance
    of each Portfolio, which may be greater or less than 5%. Annual Operating
    Expenses actually incurred by ILA Service Units of the Portfolios during
    the fiscal year ended December 31, 1995 (expressed as a percentage of
    average daily net assets after fee adjustments and expense limitations)
    were as follows: Management Fees, Service Fees and Other Expenses for the
    Prime Obligations Portfolio of 0.35%, 0.40% and 0.05%, respectively for
    Total Operating Expenses of 0.80%; for the Tax-Exempt Diversified Portfolio
    of 0.25%, 0.40% and 0.05%, respectively for Total Operating Expenses of
    0.70%. See "Management".     
(2) Goldman Sachs Asset Management (the "Adviser" or "GSAM") has agreed to
    reduce or otherwise limit certain expenses of the Portfolios (excluding
    fees payable to Service Organizations, as defined herein,
 
                                       3
<PAGE>

     
   distribution and authorized dealer service fees, taxes, interest, brokerage
   and litigation, indemnification and other extraordinary expenses), on an
   annualized basis, to 0.41% of the average daily net assets of each
   Portfolio, less the effect of fee reductions, if any. The Adviser has agreed
   that a portion of its fees will not be imposed for the Tax-Exempt
   Diversified Portfolio. Had the reduction of fees otherwise payable and
   expense limitations not been reflected in the above table, the management
   fees payable by the Tax-Exempt Diversified Portfolio would be 0.35% of
   average daily net assets and the amount of other expenses payable by the
   Prime Obligations Portfolio and Tax-Exempt Diversified Portfolio would be
   0.0 % and 0.0 %, respectively, of average daily net assets. Had the
   reduction of fees otherwise payable and expense limitations not been
   reflected in the above table, the annual operating expenses attributable to
   ILA Service Units and ILA Class B Units of the Prime Obligations Portfolio
   and ILA Service Units of the Tax-Exempt Diversified Portfolio would be
   0.  %,   % and 0.  %, respectively of average daily net assets.     
(3) Service Organizations, other than Goldman Sachs, may charge other fees to
    their customers who are the beneficial owners of ILA Service Units in
    connection with their customers' accounts. See "Additional Services." Such
    fees, if any, may affect the return such customers realize with respect to
    their investments.
    
+  Investors wishing to purchase Units of the Prime Obligations Portfolio are
   generally required to purchase ILA Service Units. ILA Class B Units of the
   Prime Obligations Portfolio will typically be issued only in exchange for
   Class B Shares of any other Goldman Sachs Portfolio.     
 
    
  The information set forth in the foregoing table and hypothetical example re-
lates to ILA Service Units of the Prime Obligations Portfolio and Tax-Exempt
Diversified Portfolio and ILA Class B Units of the Prime Obligations Portfolio.
The Portfolios also offer ILA Units and ILA Administration Units which are sub-
ject to different fees and expenses (which affect performance), have different
minimum investment requirements and are entitled to different services than ILA
Service Units and ILA Class B Units. Information regarding ILA Units and ILA
Administration Units may be obtained from your sales representative or from
Goldman Sachs by calling the number on the front cover of this prospectus. Be-
cause of the Distribution and Service Plans, long-term unitholders may pay more
than the economic equivalent of the maximum front-end sales charge permitted by
the National Association of Securities Dealers, Inc.'s rules regarding invest-
ment companies.     
 
                              FINANCIAL HIGHLIGHTS
 
    
  The following data with respect to a unit of the Prime Obligations Portfolio
and Tax-Exempt Diversified Portfolio outstanding during the periods indicated
have been audited by Arthur Andersen LLP, independent auditors, as indicated in
their report incorporated by reference and attached to the Statement of
Additional Information from the annual report to unitholders for the fiscal
year ended December 31, 1995 (the "Annual Report"), and should be read in
conjunction with the financial statements and related notes incorporated by
reference and attached to the Statement of Additional Information. ILA Class B
Units are a new class of units. Accordingly, no historical per unit data and
ratios exist for ILA Class B Units.

                       AN INTRODUCTION TO THE PORTFOLIOS
 
  The Trust is an open-end, management investment company registered under the
Investment Company Act of 1940, as amended (the "Investment Company Act"). This
Prospectus relates to the offering of ILA Service Units of the Prime Obliga-
tions Portfolio and Tax-Exempt Diversified Portfolio (the "Portfolios") and ILA
Class B Units of the Prime Obligations Portfolio. ILA Class B Units will typi-
cally be issued only upon an exchange of Class B Shares of any other Goldman
Sachs Portfolio. Goldman Sachs Asset Management, a separate operating division
of Goldman, Sachs & Co. ("Goldman Sachs"), serves as the Portfolios' investment
adviser (the "Adviser" or "GSAM"). Goldman Sachs, which serves as the Portfo-
lios' distributor and transfer agent, is one of the largest international in-
vestment banking and brokerage firms in the United States.
 
  The Portfolios are designed for investors seeking a high rate of return, a
stable net asset value and convenient liquidation privileges. Each Portfolio
seeks to maintain a stable net asset value of $1.00 per unit. To facilitate
this goal, each Portfolio's securities are valued by the amortized cost method
as permitted by a rule of the Securities and Exchange Commission ("SEC"). The
SEC rule requires, among other things, that all portfolio securities have at
the time of purchase a maximum remaining maturity of thirteen months and that
each Portfolio maintain a dollar-weighted average portfolio maturity of not
more than ninety (90) days. Investments by each Portfolio must present minimal
credit risk.
 
  The Prime Obligations Portfolio may only purchase "First Tier Securities" as
defined herein. First Tier Securities are securities which are rated (or that
have been issued by an issuer that is rated with respect to a class of short-
term debt obligations, or any security within that class, comparable in prior-
ity and quality with such securities) in the highest short-term rating category
by at least two nationally recognized statistical rating organizations
("NRSROs"), or if only one NRSRO has assigned a rating by that NRSRO.
 
  Securities which are unrated may be purchased only if they are deemed to be
of comparable quality to First Tier Securities or, in the case of Tax-Exempt
Diversified Portfolio, "Second Tier Securities" as defined herein. The Tax-Ex-
empt Diversified Portfolio may invest in First and Second Tier Securities. Sec-
ond Tier Securities are securities rated in the top two short-term rating cate-
gories by at least two NRSROs, or if only one NRSRO has assigned a rating, by
that NRSRO, but which are not First Tier Securities. Purchases of securities
which are unrated or rated by only one NRSRO must be approved or ratified by
the Trustees, except for purchases made on behalf of the Tax-Exempt Diversified
Portfolio.
 
  NRSROs include Standard & Poor's Ratings Group, Moody's Investors Service,
Inc., Fitch Investors Service, Inc., Duff and Phelps, Inc., IBCA Limited and
its affiliate IBCA Inc., and Thomson BankWatch, Inc. For a description of each
NRSRO's rating categories, see Appendix A to the Statement of Additional Infor-
mation.

      INVESTMENT OBJECTIVE AND POLICIES OF THE PRIME OBLIGATIONS PORTFOLIO
 
  The investment objective of the Prime Obligations Portfolio is to maximize
current income to the extent consistent with the preservation of capital and
the maintenance of liquidity by investing exclusively in high quality money
market instruments. The Portfolio pursues its objective by investing exclu-
sively in the following instruments:
 
  (A) securities issued or guaranteed as to principal and interest by the
      U.S. Government, its agencies, authorities or instrumentalities ("U.S.
      Government Securities");
 
  (B) obligations issued or guaranteed by U.S. banks (including certificates
      of deposit, commercial paper, unsecured bank promissory notes and bank-
      ers' acceptances) which have more than $1 billion in total assets at
      the time of purchase. Such obligations may also include debt obliga-
      tions issued by U.S. subsidiaries of such banks;
 
  (C) commercial paper (including variable amount master demand notes and as-
      set-backed commercial paper) issued or guaranteed by U.S. corporations,
      U.S. commercial banks, or other entities;
 
  (D) unrated notes, paper or other instruments which are determined to be of
      comparable high quality by the Adviser pursuant to criteria approved by
      the Trustees;
 
  (E) other short-term obligations issued or guaranteed by U.S. corporations,
      or other entities (including short-term funding agreements);
 
  (F) other short-term obligations issued or guaranteed by state and munici-
      pal governments (such securities may be purchased when yields on such
      securities are attractive when compared to other taxable investments;

    
  (G) asset-backed securities (including interests in pools of assets such as
      motor vehicle installment purchase obligations and credit card receiv-
      ables); and     
 
  (H) repurchase agreements.
 
  The Portfolio may acquire any of the above securities on a forward commitment
or when-issued basis.
 
   INVESTMENT OBJECTIVE AND POLICIES OF THE TAX-EXEMPT DIVERSIFIED PORTFOLIO
 
  The investment objective of the Tax-Exempt Diversified Portfolio is to pro-
vide its unitholders, to the extent consistent with the preservation of capital
and prescribed portfolio standards, with a high level of income exempt from
federal income tax by investing primarily in Municipal Instruments, as defined
below. The Portfolio pursues its objective by investing primarily in obliga-
tions issued by or on behalf of states, territories and possessions of the
United States and their political subdivisions, agencies, authorities and in-
strumentalities, and the District of Columbia ("Municipal Instruments"), the
interest from which is, in the opinion of bond counsel, if any, excluded from
gross income for federal income tax purposes. Such Municipal Instruments may
include:
 
  (A) fixed rate notes and similar debt instruments rated in the highest
      short-term rating category or in one of the two highest long-term rat-
      ing categories of at least one NRSRO;
 
  (B) variable and floating rate demand instruments rated (i) in the highest
      rating category for municipal notes or (ii) in one of the two highest
      rating categories for long- term instruments or (iii) in the highest
      rating category for commercial paper and municipal notes with demand
      features of at least one NRSRO;
 
  (C) tax-exempt commercial paper rated in the highest rating category of at
      least one NRSRO;
 
  (D) unrated notes, paper or other instruments which are determined to be of
      comparable high quality by the Adviser pursuant to criteria approved by
      the Trustees; and
 
                                       8
<PAGE>
 
  (E) municipal bonds rated in one of the two highest rating categories of at
      least one NRSRO and unrated bonds determined to be of comparable qual-
      ity by the Adviser pursuant to criteria approved by the Trustees.
 
  The Portfolio may acquire any of the above securities on a forward commitment
or when-issued basis.
 
  As a matter of fundamental policy, at least 80% of the Portfolio's annual
gross income will be derived from Municipal Instruments, except in extraordi-
nary circumstances. For example, the Portfolio may temporarily invest in tax-
able money market instruments when the Adviser believes that market conditions
dictate a defensive posture. Investments in taxable money market instruments
will be limited to those meeting the quality standards of the Portfolio.
 
              DESCRIPTION OF SECURITIES AND INVESTMENT TECHNIQUES
 
U.S. GOVERNMENT SECURITIES
 
  U.S. Government Securities are obligations issued or guaranteed by the U.S.
Government, its agencies, authorities or instrumentalities. Some U.S. Govern-
ment Securities, such as Treasury bills, notes and bonds, which differ only in
their interest rates, maturities and times of issuance, are supported by the
full faith and credit of the United States. Others, such as obligations issued
or guaranteed by U.S. Government agencies, authorities or instrumentalities are
supported either by (a) the full faith and credit of the U.S. Government (such
as securities of the Government National Mortgage Association), (b) the right
of the issuer to borrow from the Treasury (such as securities of the Student
Loan Marketing Association), (c) the discretionary authority of the U.S. Gov-
ernment to purchase the agency's obligations (such as securities of the Federal
National Mortgage Association and the Federal Home Loan Mortgage Corporation),
or (d) only the credit of the issuer. No assurance can be given that the U.S.
Government will provide financial support to U.S. Government agencies, authori-
ties or instrumentalities in the future. U.S. Government Securities may include
zero coupon bonds. Such bonds may be purchased when yields are attractive.
 
  Securities guaranteed as to principal and interest by the U.S. Government,
its agencies, authorities or instrumentalities are deemed to include (a) secu-
rities for which the payment of principal and interest is backed by an irrevo-
cable letter of credit issued by the U.S. Government, its agencies, authorities
or instrumentalities and (b) participations in loans made to foreign govern-
ments or their agencies that are so guaranteed. The secondary market for cer-
tain of these participations is limited. Such participations may therefore be
regarded as illiquid.
 
  Each Portfolio may also invest in separately traded principal and interest
components of securities guaranteed or issued by the U.S. Treasury if such com-
ponents are traded independently under the Separate Trading of Registered In-
terest and Principal of Securities program ("STRIPS").
 
CUSTODIAL RECEIPTS
 
  Each Portfolio may also acquire securities issued or guaranteed as to princi-
pal and interest by the U.S. Government, its agencies, authorities or instru-
mentalities in the form of custodial receipts that evidence ownership of future
interest payments, principal payments or both on certain notes or bonds issued
by the U.S. Government, its agencies, authorities or instrumentalities. For
certain securities law purposes, custodial receipts are not considered obliga-
tions of the U.S. Government.
 
MUNICIPAL INSTRUMENTS
 
  Municipal notes include tax anticipation notes ("TANs"), revenue anticipation
notes ("RANs"), bond anticipation notes ("BANs"), tax and revenue anticipation
notes ("TRANs") and construction loan notes. Municipal bonds include general
obligation bonds and revenue bonds. General obligation bonds are backed by the
taxing power of the issuing
 
                                       9

municipality and are considered the safest type of bonds. Revenue bonds are
backed by the revenues of a project or facility such as the tolls from a toll
bridge. Revenue bonds also include lease rental revenue bonds which are issued
by a state or local authority for capital projects and are secured by annual
lease payments from the state or locality sufficient to cover debt service on
the authority's obligations. To the extent that a Portfolio invests in unrated
lease rental revenue bonds, the Trustees will monitor on an ongoing basis the
credit quality of such bonds and the risks of cancellation of the underlying
leases. Industrial development bonds (generally referred to under current tax
law as "private activity bonds") are a specific type of revenue bond backed by
the credit and security of a private user and therefore have more potential
risk. Municipal bonds may be issued in a variety of forms, including commer-
cial paper, tender option bonds and variable and floating rate securities.
 
  A tender option bond is a Municipal Instrument (generally held pursuant to a
custodial arrangement) having a relatively long maturity and bearing interest
at a fixed rate substantially higher than prevailing short-term, tax-exempt
rates. The bond is typically issued in conjunction with the agreement of a
third party, such as a bank, broker-dealer or other financial institution,
pursuant to which such institution grants the security holder the option, at
periodic intervals, to tender its securities to the institution and receive
the face value thereof. As consideration for providing the option, the finan-
cial institution receives periodic fees equal to the difference between the
bond's fixed coupon rate and the rate, as determined by a remarketing or simi-
lar agent at or near the commencement of such period, that would cause the se-
curities, coupled with the tender option, to trade at par on the date of such
determination. Thus, after payment of this fee, the security holder effec-
tively holds a demand obligation that bears interest at the prevailing short-
term, tax-exempt rate. However, an institution will not be obligated to accept
tendered bonds in the event of certain defaults or a significant downgrading
in the credit rating assigned to the issuer of the bond. The tender option
will be taken into account in determining the maturity of the tender option
bonds and a Portfolio's average portfolio maturity. There is a risk that a
Portfolio will not be considered the owner of a tender option bond for federal
income taxes purposes and thus will not be entitled to treat such interest as
exempt from federal income tax.
 
  Revenue Anticipation Warrants ("RAWs") are issued in anticipation of the is-
suer's receipt of revenues and present the risk that such revenues will be in-
sufficient to satisfy the issuer's payment obligations. The entire principal
amount of principal and interest on RAWs is due at maturity. RAWs have been
issued with maturities of up to 22 months. RAWs may also be repackaged as in-
struments which include a demand feature that permits the holder to put the
RAWs to a bank or other financial institution at a purchase price equal to par
plus accrued interest on each interest rate reset date.
 
  The value of floating and variable rate obligations generally is more stable
than that of fixed rate obligations in response to changes in interest rate
levels. Variable and floating rate obligations usually carry rights that per-
mit the Portfolios to sell them at par value plus accrued interest upon short
notice. The issuers or financial intermediaries providing rights to sell may
support their ability to purchase the obligations by obtaining credit with li-
quidity supports. These may include lines of credit, which are conditional
commitments to lend, and letters of credit, which will ordinarily be irrevoca-
ble, both of which may be issued by domestic banks or foreign banks which have
a branch, agency or subsidiary in the United States. When considering whether
an obligation meets a Portfolio's quality standards, the Portfolio will look
to the creditworthiness of the party providing the right to sell as well as to
the quality of the obligation itself. A Portfolio may consider the maturity of
a variable or floating rate Municipal Instrument to be shorter than its ulti-
mate stated maturity if the Portfolio has the right to demand prepayment of
its principal at specified intervals prior to the security's ultimate stated
maturity, subject to the conditions for using amortized cost valuation under
the Investment Company Act. A
 
                                      10
<PAGE>
 
Portfolio may purchase such variable or floating rate obligations from the is-
suers or may purchase certificates of participation, a type of floating or
variable rate obligation, which are interests in a pool of municipal obliga-
tions held by a bank or other financial institution.
 
  The Portfolios may invest in industrial development bonds (generally referred
to under current tax law as "private activity bonds"), the interest from which
would be an item of tax preference when distributed as "exempt interest divi-
dends" to unitholders under the federal alternative minimum tax. See "Taxes"
and "Distributions." Any such interest which the Tax-Exempt Diversified Portfo-
lio might earn will not be deemed to have been derived from Municipal Instru-
ments for purposes of determining whether at least 80% of the Portfolio's an-
nual gross income has been derived from such Instruments. The Tax-Exempt Diver-
sified Portfolio does not currently intend to invest in such bonds.
 
  Ordinarily, the Tax-Exempt Diversified Portfolio expects that 100% of its
portfolio securities will be Municipal Instruments. However, the Portfolio may
hold cash or invest in short-term taxable securities as set forth above. The
Portfolio may invest 25% or more of the value of its total assets in Municipal
Instruments which are related in such a way that an economic, business or po-
litical development or change affecting one Municipal Instrument would also af-
fect the other Municipal Instruments. For example, the Portfolio may invest all
of its assets in (a) Municipal Instruments the interest on which is paid solely
from revenues from similar projects such as hospitals, electric utility sys-
tems, multi-family housing, nursing homes, commercial facilities (including ho-
tels), steel companies or life care facilities, (b) Municipal Instruments whose
issuers are in the same state, or (c) industrial development obligations. Con-
centration of the Portfolio's investments in Municipal Instruments in any of
the foregoing will subject the Portfolio, to a greater extent than if such in-
vestment was more limited, to the risks of adverse economic, business or polit-
ical developments affecting any such state, industry or other area of concen-
tration.
 
  Each Portfolio may purchase Municipal Instruments which are backed by letters
of credit, which will ordinarily be irrevocable, issued by domestic banks or
foreign banks which have a branch, agency or subsidiary in the United States.
In addition, such Portfolios may acquire securities in the form of custodial
receipts which evidence ownership of future interest payments, principal pay-
ments or both on obligations of certain state and local governments and author-
ities.
 
  In order to enhance the liquidity, stability, or quality of a Municipal In-
strument, each Portfolio may acquire the right to sell the security to another
party at a guaranteed price and date. These rights may be referred to as puts,
demand features, or standby commitments.
 
    
ASSET-BACKED AND RECEIVABLES-BACKED SECURITIES     
 
    
  The Prime Obligations Portfolio may invest in asset-backed and receivables-
backed securities. These securities represent participations in, or are secured
by and payable from, pools of assets such as motor vehicle installment sale
contracts, installment loan contracts, leases of various types of real and per-
sonal property, receivables from revolving credit (credit card) agreements and
other categories of receivables. Such asset pools are securitized through the
use of privately-formed trusts or special purpose-corporations. Payments or
distributions of principal and interest may be guaranteed up to certain amounts
and for a certain time period by a letter of credit or a pool insurance policy
issued by a financial institution or other credit enhancements may be present.
     
 
  The Portfolio may invest in new types of mortgage-related securities and in
other asset-backed securities that may be developed in the future to the extent
consistent with its investment objective and policies.
 
REPURCHASE AGREEMENTS
 
  Each Portfolio may enter into repurchase agreements with selected broker-
dealers, banks or
 
                                       11
<PAGE>
 
other financial institutions. A repurchase agreement is an agreement under
which a Portfolio purchases securities and the seller agrees to repurchase the
securities within a particular time at a specified price. Such price will ex-
ceed the original purchase price, the difference being income to the Portfolio,
and will be unrelated to the interest rate on the purchased security. A Portfo-
lio's custodian or sub-custodian will maintain custody of the purchased securi-
ties for the duration of the agreement. The value of the purchased securities,
including accrued interest, will at all times exceed the value of the repur-
chase agreement. In the event of bankruptcy of the seller or failure of the
seller to repurchase the securities as agreed, a Portfolio could suffer losses,
including loss of interest on or principal of the security and costs associated
with delay and enforcement of the repurchase agreement. In evaluating whether
to enter into a repurchase agreement, the Adviser will carefully consider the
creditworthiness of the seller pursuant to procedures reviewed and approved by
the Trustees. Distributions of the income from repurchase agreements entered
into by a Portfolio will be taxable to its unitholders. In addition, each Port-
folio, together with other registered investment companies having advisory
agreements with the Adviser or any of its affiliates, may transfer uninvested
cash balances into a single joint account, the daily aggregate balance of which
will be invested in one or more repurchase agreements.
 
FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES
 
  The Portfolios may purchase when-issued securities and make contracts to pur-
chase or sell securities for a fixed price at a future date beyond customary
settlement time. A Portfolio is required to hold and maintain in a segregated
account with the Portfolio's custodian or subcustodian until the settlement
date, cash or liquid, high grade debt obligations in an amount sufficient to
meet the purchase price. Alternatively, a Portfolio may enter into offsetting
contracts for the forward sale of other securities that it owns. Securities
purchased or sold on a when-issued or forward commitment basis involve a risk
of loss if the value of the security to be purchased declines prior to the set-
tlement date or if the value of the security to be sold increases prior to the
settlement date. Although a Portfolio would generally purchase securities on a
when-issued or forward commitment basis with the intention of acquiring securi-
ties for its portfolio, the Portfolio may dispose of a when-issued security or
forward commitment prior to settlement if the Adviser deems it appropriate to
do so.
 
OTHER INVESTMENT COMPANIES
 
  Each Portfolio may invest in securities issued by other money market invest-
ment companies. Such investments will be determined by the Adviser, under
guidelines established by the Trustees, to present minimal credit risks. The
amount of a Portfolio's investments in securities of other investment companies
will be subject to the limitations on such investments prescribed by the In-
vestment Company Act and certain state securities regulations. These limits in-
clude a prohibition on any Portfolio acquiring more than 3% of the voting
shares of any other investment company, and a prohibition on investing more
than 5% of a Portfolio's assets in securities of any one investment company or
more than 10% of its assets in securities of all investment companies. Each
Portfolio will indirectly bear its proportionate share of any management fees
and other expenses paid by such other investment companies. Goldman Sachs will
not impose a portion of the management fees payable by a Portfolio (the "Ac-
quiring Portfolio") with respect to assets invested in another money market in-
vestment company (the "Acquired Portfolio") as follows. The amount of the man-
agement fees otherwise payable by the Acquiring Portfolio and not imposed by
Goldman Sachs will be equal to the amount of management fees indirectly paid by
the Acquiring Portfolio as a unitholder of the Acquired Portfolio. Such other
investment companies will have investment objectives, policies and restrictions
substantially similar to those of the Acquiring Portfolio and will be subject
to substantially the same risks.

                             INVESTMENT LIMITATIONS
 
  PRIME OBLIGATIONS PORTFOLIO. Pursuant to SEC Rule 2a-7 under the Investment
Company Act, the Prime Obligations Portfolio may not invest more than 5% of its
assets (taken at amortized cost) in the securities of any one issuer (except
U.S. Government Securities and repurchase agreements collateralized by such se-
curities). The Portfolio may, however, invest more than 5% of its assets in the
First Tier Securities of a single issuer for a period of up to three business
days after the purchase thereof, although the Portfolio may not make more than
one such investment at any time. The Prime Obligations Portfolio may not invest
in securities which are Second Tier Securities at the time of purchase. Immedi-
ately after the acquisition of any put by the Portfolio, not more than 5% of
such Portfolio's total assets may be invested in securities issued by or sub-
ject to puts from the same issuer. However, this limitation will not apply to
the issuer of unconditional puts if the Portfolio does not have more than 10%
of its total assets invested in securities issued by or subject to uncondi-
tional puts from such issuer. Pursuant to SEC Rule 2a-7 the foregoing restric-
tions are not applicable to the Tax-Exempt Diversified Portfolio. The foregoing
operating policies are more restrictive than the fundamental policy set forth
below, which would give the Prime Obligations Portfolio the ability to invest
with respect to 25% of its assets, more than 5% of its assets in any one issu-
er. The Prime Obligations Portfolio will operate in accordance with these oper-
ating policies which comply with SEC Rule 2a-7.
 
  TAX-EXEMPT DIVERSIFIED PORTFOLIO. Pursuant to SEC Rule 2a-7, immediately af-
ter the acquisition of any put by the Tax-Exempt Diversified Portfolio, not
more than 5% of the Portfolio's total assets may be invested in securities is-
sued by or subject to puts from the same issuer. However, this limitation ap-
plies only with respect to 75% of the Portfolio's total assets. Also, with re-
spect to such Portfolio, this limitation will not apply to the issuer of uncon-
ditional puts if the Portfolio does not have more than 10% of its total assets
invested in securities issued by or subject to unconditional puts from such is-
suer. The Portfolio will operate in accordance with this operating policy which
complies with SEC Rule 2a-7.
 
INVESTMENT RESTRICTIONS
 
  The Trust, on behalf of each Portfolio, has adopted certain fundamental in-
vestment restrictions which are enumerated in detail in the Statement of Addi-
tional Information and which may not be changed with respect to a Portfolio un-
less authorized by a majority of its outstanding units. Among other restric-
tions, a Portfolio may not, with respect to 75% of its total assets taken at
market value, invest more than 5% of its total assets in the securities of any
one issuer (except U.S. Government Securities and repurchase agreements
collaterized by such securities) or acquire more than 10% of any class of the
outstanding voting securities of any one issuer. In addition, each Portfolio
may not invest more than 25% of its total assets in securities of issuers in
any one industry (the electric, gas, water and telephone utility industries be-
ing treated as separate industries for the purpose of the restriction), pro-
vided that there is no 25% limitation in respect of, and each Portfolio re-
serves freedom of action to concentrate its investments in, U.S. Government Se-
curities, obligations (other than commercial paper) issued or guaranteed by
U.S. banks and U.S. branches of foreign banks, provided such branches are sub-
ject to the same regulations as U.S. banks, and repurchase agreements and loans
of securities collateralized by U.S. Government Securities or such bank obliga-
tions, provided the investment policies of the Portfolio permit the particular
investment. Tax diversification requirements for qualification as a regulated
investment company apply to the Portfolios and are in certain instances more
strict than these investment restrictions. In applying the above restrictions,
a Portfolio will not treat a guarantee as a security issued by the guarantor if
the value of all securities issued or guaranteed by the guarantor and owned by
a Portfolio does not exceed 10% of its total assets.
 
  Each Portfolio may borrow money as a temporary measure in amounts not exceed-
ing 5% of its
 
                                       13
<PAGE>
 
total assets or from banks in an aggregate amount not exceeding one-third of
the value of its total assets. A Portfolio may not purchase securities while
such borrowings exceed 5% of the value of its total assets. The investment re-
strictions listed above are fundamental policies and accordingly may not be
changed with respect to a Portfolio without the approval of the majority of the
outstanding units of that Portfolio. The investment objective of each Portfolio
is fundamental and may not be changed without a vote of the unitholders. Howev-
er, the investment policies and practices of each Portfolio, unless otherwise
specifically stated, are not fundamental.
 
RESTRICTED AND OTHER ILLIQUID SECURITIES
 
  Each Portfolio may purchase securities that are not registered ("restricted
securities") under the Securities Act of 1933 ("1933 Act"), but can be offered
and sold to "qualified institutional buyers" under Rule 144A under the 1933
Act. However, a Portfolio will not invest more than 10% of its net assets in
illiquid investments, which includes fixed time deposits maturing in more than
seven days and restricted securities. Restricted securities (including commer-
cial paper issued pursuant to Section 4(2) of the 1933 Act) which the Board of
Trustees has determined are liquid, based upon a continuing review of the trad-
ing markets for the specific restricted security, will not be deemed to be il-
liquid investments for purposes of this restriction. The Board of Trustees may
adopt guidelines and delegate to the Adviser the daily function of determining
and monitoring the liquidity of restricted securities. The Board, however, will
retain sufficient oversight and be ultimately responsible for the determina-
tions. Since it is not possible to predict with assurance that the market for
restricted securities eligible for resale under Rule 144A will continue to be
liquid, the Board will carefully monitor each Portfolio's investments in these
securities, focusing on such important factors, among others, as valuation, li-
quidity and availability of information. This investment practice could have
the effect of increasing the level of illiquidity in a Portfolio to the extent
that qualified institutional buyers become for a time uninterested in purchas-
ing these restricted securities.
 
  In addition, each Portfolio may not invest in repurchase agreements maturing
in more than seven days and securities which are not readily marketable if, as
a result thereof, more than 10% of the net assets of that Portfolio (taken at
market value) would be invested in such investments. Certain repurchase agree-
ments which mature in more than seven days can be liquidated before the nominal
fixed term on seven days or less notice. Such repurchase agreements will be re-
garded as liquid instruments.
 
                                   MANAGEMENT
 
THE ADVISER

     
  GSAM, One New York Plaza, New York, New York, a separate operating division
of Goldman Sachs, acts as investment adviser to the Portfolios. Goldman Sachs
registered as an investment adviser in 1981. As of January 31, 1996, Goldman
Sachs, together with its affiliates, acted as investment adviser, administrator
or distributor for approximately $57 billion in assets.     

     
  As of November 25, 1995, Goldman Sachs and its consolidated subsidiaries had
assets of approximately $70.7 billion and partners' capital of $1.9 billion and
ranked as one of the largest international investment banking and brokerage
firms in the United States. Founded in 1869, Goldman Sachs is a major player
among investment banking and brokerage firms providing a broad range of financ-
ing and investing services both in the United States and abroad.     
 
  Pursuant to an SEC order, the Prime Obligations Portfolio may enter into
principal transactions in certain taxable money market instruments, including
repurchase agreements, with Goldman Sachs or its affiliate, Goldman Sachs Money
Market, L.P.
 
  Under its Investment Advisory Agreement with the Trust, GSAM continually man-
ages each
 
                                       14
<PAGE>
 
Portfolio, including the purchase, retention and disposition of its securities
and other assets. In addition, GSAM administers the Portfolios' business af-
fairs and performs various unitholder servicing functions to the extent not
provided by other organizations. GSAM may pay a Service Organization, as de-
fined herein, other than Goldman Sachs, compensation equal on an annual basis
up to .10% of the average daily net assets of the ILA Service Units held of
record by such Service Organization for providing certain unitholder services
to its customers. The management of each Portfolio is subject to the supervi-
sion of the Board of Trustees and each Portfolio's investment policies. For
these services, the Trust, on behalf of each Portfolio, pays GSAM a monthly
fee at an annual rate of each Portfolio's average daily net assets as follows:

  The difference, if any, between the stated advisory fee and the actual advi-
sory fees paid by the Portfolios reflects the fact that GSAM did not charge
the full amount of the advisory fees to which it would have been entitled.
 
    
  GSAM has agreed to reduce or otherwise limit the daily expenses of each
Portfolio (excluding fees payable to Service Organizations, as defined herein,
distribution and authorized dealer service fees, taxes, interest, brokerage
and litigation, indemnification and other extraordinary expenses), on an
annualized basis, to .43% of the average daily net assets of the Portfolio
less the effect of fee reductions, if any. Such reductions or limits, if any,
are calculated monthly on a cumulative basis. Any such reductions or limits
may be discontinued or modified only with the express approval of the Trust-
ees. In addition, GSAM has voluntarily agreed not to impose all or a portion
of its advisory fee and/or to reduce or otherwise limit the Prime Obligations
and Tax-Exempt Diversified Portfolios' annual total operating expenses (ex-
cluding fees payable to Service Organizations, as defined herein and distribu-
tion and authorized dealer service fees), to .41% and .31%, respectively, of
average daily net assets. GSAM has no current intention to, but may in the fu-
ture, discontinue or modify the voluntary limitation at its discretion.     
 
    
  From time to time, Goldman Sachs or any of its affiliates may purchase and
hold units of the Portfolios in order to increase the assets of the Portfo-
lios. Increasing the Portfolios' assets may enhance investment flexibility and
diversification. Goldman Sachs reserves the right to redeem at any time some
or all of the Portfolio units acquired for its own account. Goldman Sachs will
consider the effect of redemptions on the Portfolios and other unitholders in
deciding whether to redeem its units.     
 
THE DISTRIBUTOR AND TRANSFER AGENT
 
    
  Goldman Sachs, 85 Broad Street, New York, New York, serves as the Distribu-
tor of units of each Portfolio pursuant to a Distribution Agreement with the
Trust. The Distributor will assist in the sale of units of each Portfolio upon
the terms described herein. Units of each Portfolio may also be sold by cer-
tain investment dealers, including members of the National Association of Se-
curities Dealers, Inc. and certain other financial service firms that have
sales agreements with Goldman Sachs ("Authorized Dealers"). Goldman Sachs,
4900 Sears Tower, Chicago, Illinois also serves as the Transfer Agent of each
Portfolio.     
 
                              ADDITIONAL SERVICES
                              
                           (ILA SERVICE UNITS ONLY)     
 
  Each Portfolio has adopted a Service Plan with respect to the ILA Service
Units which authorizes it to compensate Service Organizations for providing
account administration and personal and account maintenance services to their
customers who are beneficial owners of such Units. Each Portfolio will
 
                                      15
<PAGE>
 
enter into agreements with Service Organizations, including Goldman Sachs,
which purchase ILA Service Units, on behalf of their customers ("Service Agree-
ments"). On behalf of its clients who purchase ILA Service Units of a Portfo-
lio, Goldman Sachs will provide services as set forth under the Service Agree-
ment. The Service Agreements will provide for compensation to each Service Or-
ganization in an amount up to .40 of 1% (on an annualized basis) of the average
daily net assets of the ILA Service Units of that Portfolio attributable to or
held in the name of the Service Organization for its customers; provided, how-
ever, that the fee paid for personal and account maintenance services shall not
exceed .25% of such average daily net assets. The services provided by a Serv-
ice Organization may include acting, directly or through an agent, as the sole
unitholder of record, maintaining account records for its customers, processing
orders to purchase, redeem and exchange ILA Service Units for its customers,
responding to inquiries from prospective and existing unitholders and assisting
customers with investment procedures.
 
  For the fiscal year ended December 31, 1995, the Trust, on behalf of each
Portfolio, paid Service Organizations fees at the annual rate of .40% of each
Portfolio's average daily net assets attributable to ILA Service Units.
 
  Holders of ILA Service Units of a Portfolio will bear all expenses and fees
paid to Service Organizations with respect to such Units as well as any other
expenses which are directly attributable to such Units.
 
         

  Service Organizations, other than Goldman Sachs, may charge other fees to
their customers who are the beneficial owners of ILA Service Units in connec-
tion with their customer accounts. These fees would be in addition to any
amounts received by the Service Organization under a Service Agreement and may
affect an investor's return with respect to an investment in a Portfolio.
 
  All inquiries of beneficial owners of ILA Service Units of the Portfolios
should be directed to such owners' Service Organization.
 
    
DISTRIBUTION AND AUTHORIZED DEALER SERVICE PLANS (ILA CLASS B UNITS ONLY)     
 
    
  DISTRIBUTION PLAN-CLASS B UNITS. Prime Obligations Portfolio, with respect to
its ILA Class B Units, has adopted a Distribution Plan pursuant to Rule 12b-1
under the Investment Company Act (the "Class B Distribution Plan"). Under the
Class B Distribution Plan, Goldman Sachs is entitled to a quarterly fee from the
Portfolio for distribution serv-ices equal, on an annual basis, to 0.75% of the
Portfolio's average daily net assets attributable to its ILA Class B Units.     

     
  Goldman Sachs may use the distribution fee for its expenses of distributing
the ILA Class B Units. The types of expenses for which Goldman Sachs may be
compensated for distribution services under the Class B Distribution Plan in-
clude compensation paid to and expenses incurred by authorized dealers, Goldman
Sachs and their respective officers, employees and sales representatives, com-
missions paid to authorized dealers, allocable overhead, telephone and travel
expenses, the printing of prospectuses for prospective unitholders, preparation
and distribution of sales literature, advertising of any type and all other ex-
penses incurred in connection with activities primarily intended to result in
the sale of ILA Class B Units. If the fee received by Goldman Sachs pursuant to
the Class B Distribution Plan exceeds its expenses, Goldman Sachs may realize a
profit from these arrangements. The Class B Distribution Plan will be reviewed
and is subject to approval annually by the Board of Trustees of the Trust. The
aggregate compensation that may be received under the Class B Distribution Plan
for distribution services may not exceed the limitations imposed by the NASD's
Rules of Fair Practice.     
 
    
  AUTHORIZED DEALER SERVICE PLAN-CLASS B UNITS. Prime Obligations Portfolio,
with respect to its ILA Class B Units, has adopted a non-Rule 12b-1 Authorized
Dealer Service Plan (an "Authorized Dealer Service Plan") pursuant to which
Goldman Sachs and authorized dealers are compensated for providing personal and
account mainte-     
 
                                       16
<PAGE>

     
nance services. The Portfolio pays a fee under its Authorized Dealer Service
Plan equal on an annual basis to 0.25% of its average daily net assets attrib-
utable to its ILA Class B Units. The fee for personal and account maintenance
services paid pursuant to an Authorized Dealer Service Plan may be used to
make payments to Goldman Sachs, authorized dealers and their officers, sales
representatives and employees for responding to inquiries of, and furnishing
assistance to, unitholders regarding ownership of their units or their accounts
or similar services not otherwise provided on behalf of the Portfolios. The Au-
thorized Dealer Service Plans will be reviewed and are subject to approval an-
nually by the Board of Trustees.     

     
ALTERNATIVE PURCHASE ARRANGEMENTS     
 
    
  Each Portfolio continuously offers ILA Service Units and the Prime Obliga-
tions Portfolio also offers ILA Class B Units through this prospectus, as de-
scribed more fully in "Purchase of Units." ILA Class B Units of the Prime Obli-
gations Portfolio will be typically issued only upon an exchange of Class B
Shares of any of the Goldman Sachs Portfolios, as defined herein. If an in-
vestor does not specify in the instructions to the Portfolios which class of
Units an investor wishes to purchase, exchange or redeem, the Portfolios will
assume that the instructions apply to ILA Service Units, since such units are
not subject to any contingent deferred sales charge or distribution fees.
 
  ILA SERVICE UNITS. ILA Service Units of the Portfolios may be purchased
through Goldman Sachs acting as a Service Organization or through Authorized
Dealers. ILA Service Units are not subject to any initial or contingent de-
ferred sales charge or any fee for distribution services. However, ILA Service
Units are subject to a service fee at the annual rate of 0.40% of the Portfo-
lios' average daily net assets attributable to ILA Service Units. See "Addi-
tional Services."
 
  ILA CLASS B UNITS. ILA Class B Units of the Prime Obligations Portfolio may
be purchased through Goldman Sachs or through Authorized Dealers. ILA Class B
Units of the Prime Obligations Portfolio are typically intended to be purchased
only in connection with exchanges of Class B Shares of any other Goldman Sachs
Portfolio. ILA Class B Units are sold without an initial sales charge, but are
subject to a contingent deferred sales charge ("CDSC"), as described below, if
redeemed within six years of purchase. ILA Class B Units are also subject to
distributions and authorized dealer service fees of up to 0.75% and 0.25%, re-
spectively, of the Portfolio's average daily net assets attributable to ILA
Class B Units. See "Distribution and Authorized Dealer Service Plans." Your en-
tire investment in ILA Class B Units is available to work for you from the time
you make your initial investment, but the distribution fee paid by ILA Class B
Units will cause your Units (until conversion to ILA Service Units) to have a
higher expense ratio and to pay lower dividends than ILA Service Units. ILA
Class B Units will automatically convert to ILA Service Units, based on their
relative net asset values, seven years after purchase. No CDSC is imposed upon
exchanges between the Prime Obligations Portfolio and another Goldman Sachs
Portfolio. However, units or shares acquired in an exchange will be subject to
the CDSC to the same extent as if there had been no exchange. For purposes of
determining whether the CDSC is applicable, the length of time an investor has
owned units or shares acquired by exchange will be measured from the date the
investor acquired the original units or shares and will not be affected by any
subsequent exchange.     
 
OFFERING PRICE-ILA CLASS B UNITS
 
  Investors may purchase ILA Class B Units of the Prime Obligations Portfolio
at the next determined net asset value without the imposition of an initial
sales charge. However, ILA Class B Units redeemed within six years of purchase
will be subject to a CDSC at the rates shown in the table that follows. At re-
demption, the charge will be assessed on the amount equal to the lesser of the
current market value or the original purchase cost of the
 
                                       17
<PAGE>

     
units being redeemed. No CDSC will be imposed on increases in account value
above the initial purchase price, including units derived from the reinvestment
of dividends or capital gains distributions.
 
  The amount of the CDSC, if any, will vary depending on the number of years
from the time of purchase until the time of redemption of ILA Class B Units.
For the purpose of determining the number of years from the time of any pur-
chase, all payments during a month will be aggregated and deemed to have been
made on the first day of that month. In processing redemptions of ILA Class B
Units, the Portfolio will first redeem units not subject to any CDSC, and then
units held longest during the seven-year period. As a result, a redeeming
unitholder will pay the lowest possible CDSC.

  Proceeds from the CDSC are payable to the Distributor and may be used in
whole or part to defray the Distributor's expenses related to providing distri-
bution-related services in connection with the sale of ILA Class B Units.
 
  ILA Class B Units of the Portfolio will automatically convert into ILA Serv-
ice Units of the Portfolio at the end of the calendar quarter that is seven
years after the purchase date, except as noted below. ILA Class B Units of the
Portfolio acquired by exchange from Class B Shares of another Goldman Sachs
Portfolio will convert into ILA Service Units based on the date of the initial
purchase. ILA Class B Units acquired through reinvestment of distributions will
convert into ILA Service Units based on the date of the initial purchase of the
units on which the distribution was paid. The conversion of ILA Class B Units
to ILA Service Units is subject to the continuing availability of a ruling from
the Internal Revenue Service, for which the Portfolio has applied, or an opin-
ion of counsel that such conversions will not constitute taxable events for
Federal tax purposes. There can be no assurance that such ruling or opinion
will be available. The conversion will not occur if such ruling or opinion is
not available and, therefore, ILA Class B Units would continue to be subject to
higher expenses than ILA Service Units for an indeterminate period.
 
  Waiver or Reduction of Contingent Deferred Sales Charge. The CDSC on ILA
Class B Units may be waived or reduced if the redemption results from the death
or disability (as defined in Section 72 of the Code), of a unitholder if the
redemption is made within one year of such event.     
 
    
GENERAL INFORMATION     
 
    
  ILA Service Units and ILA Class B Units may be purchased on any Business Day
at the net asset value next determined after receipt by State Street Bank and
Trust Company ("State Street"), as agent for Goldman Sachs, of both the pur-
chase order and the purchase price in Federal Funds. Purchase orders may be
made by contacting Goldman Sachs or, if units are held in a "street name" ac-
count, the applicable Authorized Dealer. Since the Portfolios and Goldman Sachs
will have no record of the beneficial owner's transactions in a "street name"
account, the beneficial owner should contact its Authorized Dealer to purchase,
redeem or exchange units, to make changes in or give instructions concerning
the account or to obtain information about the account. It is the responsibil-
ity of the Authorized Dealer to promptly forward orders and payment to the
Portfolios.     
 
    
  Goldman Sachs may from time to time, at its own expense, provide compensation
to certain dealers who perform administrative services with respect to deposi-
tory institutions whose customers purchase ILA Service Units of the Portfolios.
These services include responding to certain inquiries     
 
                                       18
<PAGE>
 
from and providing written materials to depository institutions about the Port-
folios; furnishing advice about and assisting depository institutions in ob-
taining from state regulatory agencies any rulings, exemptions or other autho-
rizations that may be required to conduct a mutual fund sales program; acting
as liaison between depository institutions and national regulatory organiza-
tions; assisting with the preparation of sales material; and providing general
assistance and advice in establishing and maintaining mutual fund sales pro-
grams on the premises of depository institutions.
 
    
  The amount of such compensation may be up to .08% annually of the average net
assets of each Portfolio attributable to ILA Service Units purchased through,
and held by the customers of, such depository institutions. Such compensation
does not represent an additional expense to any Portfolio or its unitholders,
since it will be paid from the assets of Goldman Sachs or its affiliates.     
 
PURCHASES BY CHECK
 
    
  Initial purchases of ILA Service Units and ILA Class B Units may be made by
mailing a completed Account Information Form along with a Federal Reserve draft
or check payable to the appropriate Portfolio and drawn on a U.S. bank and for
subsequent investments may be made by mailing a check with the investor's ac-
count number to Goldman Sachs Money Market Trust (Prime Obligations Portfolio--
Indicate Class of Units) or (Tax-Exempt Diversified Portfolio--Service Units)
Service Units, c/o NFDS, P.O. Box 419711, Kansas City, MO 64141-6711. The order
becomes effective as soon as the check or draft is converted to Federal Funds.
It is expected that Federal Reserve drafts will ordinarily be converted to Fed-
eral Funds on the day of receipt and that checks will be converted to Federal
Funds within two Business Days after receipt. Payment of redemption proceeds
from ILA Service Units and ILA Class B Units purchased by check may be delayed
up to 15 days until the check has cleared, as described under "Redemption of
Units".     
 
AUTOMATIC INVESTMENT PLAN
 
    
  Systematic cash investments in ILA Service Units or ILA Class B Units may be
made through a unitholder's bank via the Automated Clearing House Network or a
unitholder's checking account via bank draft each month. Required forms are
available from Goldman Sachs or any Authorized Dealer. A minimum investment of
$50 is required for Automatic Investment Plans.

  ILA Service Units of the Portfolios are purchased at the net asset value per
unit without the imposition of a sales charge. ILA Class B Units acquired
through an exchange will be purchased at the net asset value per unit and will
only be subject to the CDSC of the shares originally held. For purposes of de-
termining the amount of any applicable CDSC, the length of time a unitholder
has owned ILA Class B Units will be measured from the date the unitholder ac-
quired the original Class B shares and will not be affected by any subsequent
exchange. Investors should consult their Goldman

  Goldman Sachs, as each Portfolio's transfer agent, will maintain a complete
record of transactions and ILA Service Units or ILA Class B Units held in each
unitholder's account.
 
  The Trust and Goldman Sachs each reserves the right to reject any purchase
order for any reason.
 
  Goldman Sachs may, at its own expense, provide compensation to certain deal-
ers whose customers purchase significant amounts of units of a Portfolio. The
amount of such compensation may be made on a one-time and/or periodic basis,
and may be up to 25% of the annual fees that are earned by GSAM as investment
adviser to such Portfolio (after adjustments) and are attributable to units
held by such customers. Such compensation will not represent an additional ex-
pense to the Portfolio or its unitholders, since it will be paid from assets of
Goldman Sachs or its affiliates.
 
MINIMUM INVESTMENT AND OTHER INFORMATION
 
    
  The Trust does not have any minimum purchase or account requirements with re-
spect to ILA Service Units. However, Goldman Sachs has established a minimum
initial investment requirement of $10,000. Shareholders of any Goldman Sachs
Portfolio who wish to purchase ILA Service Units of the Portfolios or ILA Class
B Units of the Prime Obligations Portfolio through an exchange of shares of
such a Goldman Sachs Portfolio may be subject to different minimum investment
requirements. (See "Exchanges," on page 23 of the Prospectus.)     
 
TAX-SHELTERED RETIREMENT PLANS
 
    
  The Prime Obligations Portfolio is offered for purchase by retirement plans,
including Individual Retirement Account Plans for individuals and their non-em-
ployed spouses and defined contribution plans such as 401(k) Salary Reduction
Plans.     
 
  Detailed information concerning these plans and copies of the plans may be
obtained from the Transfer Agent. This information should be read carefully,
and consultation with an attorney or tax adviser may be advisable. The informa-
tion sets forth the service fee charged for retirement plans and describes the
federal income tax consequences of establishing a plan. Under all plans, divi-
dends and distributions will be automatically reinvested in additional units of
the Portfolio or, if so directed by the unitholder, in cash, or in shares of
another Goldman Sachs Portfolio.
 
  The minimum initial investment for all such retirement plans is $10,000, ex-
cept for certain exchanges of shares of any Goldman Sachs Portfolio and except
that the minimum for tax-sheltered retirement plans is $250. There is a minimum
of $50 for all subsequent investments.
 
                             REPORTS TO UNITHOLDERS
 
    
  The Trust will issue an annual report containing audited financial statements
and a semiannual report to record holders of ILA Service Units of each Portfo-
lio, including Service Organizations who hold such Units for the benefit of
their customers and to unitholders of ILA Class B Units of the Prime Obliga-
tions Portfolio. Upon request, a printed confirmation for each transaction will
be provided by Goldman Sachs. Any dividends and distributions paid by the Port-
folio are also reflected in regular statements issued by Goldman Sachs, in its
capacity as transfer agent and income disbursing agent, to unitholders of rec-
ord. The Service Organizations, including Goldman Sachs or their agents, as
record holders of ILA Service Units, will be responsible for providing similar
services to their own customers who are the beneficial owners of such Units.
For example, Service Organizations are responsible for providing each customer
exercising investment discretion with monthly statements with respect to such
customer's account in lieu of an immediate confirmation of each transaction.

                            DISTRIBUTIONS AND TAXES
 
DISTRIBUTIONS
 
  All or substantially all of each Portfolio's net investment income will be
declared daily (as of 4:00 p.m. New York time) as a dividend and distributed
monthly. Distributions will be made in additional ILA Service Units or ILA
Class B Units of the same Portfolio or, at the election of a Service Organiza-
tion (with respect to ILA Service Units) or ILA Class B Unitholders, in cash.
Such reinvestments will not be subject to any CDSC. The election to reinvest
dividends and distributions or receive them in cash may be changed by a Service
Organization or ILA Class B Unitholder at any time upon written notice to
Goldman Sachs, in its capacity as transfer agent and income disbursing agent.
If no election is made, all dividend and capital gain distributions will be re-
invested. Dividends will be reinvested as of the last calendar day of each
month. Cash distributions will be paid on or about the first business day of
each month. Net short-term capital gains, if any, will be distributed in accor-
dance with the requirements of the Code and may be reflected in a Portfolio's
daily distributions. Each Portfolio may distribute at least annually its long-
term capital gains, if any, after reduction by available capital losses. In or-
der to avoid excessive fluctuations in the amount of monthly capital gains dis-
tributions, a portion of any net capital gains realized on the disposition of
securities during the months of November and December may be distributed during
the subsequent calendar year. Although realized gains and losses on the assets
of a Portfolio are reflected in the net asset value of the Portfolio, they are
not expected to be of an amount which would affect the Portfolio's net asset
value of $1.00 per unit.
 
  A Portfolio's net investment income consists of the excess of (i) accrued in-
terest or discount (including both original issue and market discount on tax-
able securities) on portfolio securities, and (ii) any income of the Portfolio
from sources other than capital gains over (iii) the amortization of market
premium on all portfolio securities and (iv) the estimated expenses of the
Portfolio, including a proportionate share of the general expenses of the
Trust.
 
TAXES
 
  Each Portfolio is treated as a separate entity for federal income tax pur-
poses and intends to qualify and be treated as a regulated investment company
under Subchapter M of the Internal Revenue Code of 1986 (the "Code") for each
taxable year. To qualify as such, each Portfolio must satisfy certain require-
ments relating to the sources of its income, diversification of its assets and
distribution of its income to unitholders. As a regulated investment company,
each Portfolio will not be subject to federal income or excise tax on any net
investment income and net realized capital gains that are distributed to its
unitholders in accordance with certain timing requirements of the Code.
 
  Dividends paid by a Portfolio from net investment income (except, in the case
of the Tax-Exempt Diversified Portfolio), the excess of net short-term capital
gain over net long-term capital loss and taxable original issue discount or
market discount income will be taxable to unitholders as ordinary income. Divi-
dends paid by a Portfolio from the excess of net long-term capital gain over
net short-term capital loss will be taxable as long-term capital gain regard-
less of how long the unitholders have held their units. These tax consequences
will apply to taxable distributions of a Portfolio (including the Tax-Exempt
Diversified Portfolio which also pays exempt-interest dividends, as described
below) regardless of whether distributions are received in cash or reinvested
in units. Certain distributions paid by the Portfolios in January of a given
year will be taxable to unitholders as if received on December 31 of the year
in which they are declared. Unitholders will be informed annually about the
amount and character of distributions received from the Portfolios for federal
income tax purposes, including any distributions that may constitute a return
of capital or any distributions of the Tax-Exempt Diversified Portfolio that
may constitute a tax preference item under the federal alternative minimum tax.
 
  The Tax-Exempt Diversified Portfolio intends to satisfy certain requirements
of the Code for the
 
                                       21
<PAGE>
 
payment of "exempt-interest dividends" not included in unitholders' federal
gross income. Dividends paid by the Portfolio from interest on tax-exempt obli-
gations and properly designated by the Portfolio as exempt-interest dividends,
including exempt-interest dividends received from other regulated investment
companies, will generally be exempt from federal income tax although a portion
of such dividends may be subject to the federal alternative minimum tax. Ex-
empt-interest dividends will be considered in computing the "adjusted current
earnings" preference item for purposes of the corporate federal alternative
minimum tax, the corporate environmental tax, and the extent, if any, to which
social security or railroad retirement benefits are taxable. Persons who are
"substantial users" of facilities financed by certain industrial development or
private activity bonds should consult their own tax advisers before purchasing
units of the Portfolio. Interest incurred to purchase or carry units of the
Portfolio will not be deductible for federal income tax purposes to the extent
related to exempt-interest may not be deductible for federal or state income
tax purposes.
 
  Individuals and certain other classes of unitholders may be subject to 31%
backup withholding of federal income tax on taxable distribu-tions if they fail
to furnish their correct taxpayer identification number and certain certifica-
tions or if they are otherwise subject to backup withholding. Individuals, cor-
porations and other unitholders that are not U.S. persons under the Code are
subject to different tax rules and may be subject to nonresident alien with-
holding at the rate of 30% (or a lower rate provided by an applicable tax trea-
ty) on amounts treated as ordinary dividends from the Portfolios.
 
  In addition to federal taxes, a unitholder may be subject to state and local
taxes on payments received from a Portfolio. A state income (and possibly local
income and/or intangible property) tax exemption is generally available to the
extent a Portfolio's distributions are derived from interest on (or, in the
case of intangibles taxes, the values of its assets is attributable to) certain
U.S. Government obligations and/or tax-exempt municipal obligations issued by
or on behalf of the particular state or a political subdivision thereof, pro-
vided in some states that certain thresholds for holdings of such obligations
and/or reporting requirements are satisfied. Unitholders should consult their
own tax advisers concerning these matters.
 
                           AUTOMATIC EXCHANGE PROGRAM
 
    
  Unitholders of a Portfolio may elect on the Account Information Form to auto-
matically exchange a specified dollar amount of ILA Service Units or ILA Class
B Units for corresponding shares of any Goldman Sachs Portfolio. In the case of
ILA Service Units, such exchanges will be made into the relevant Goldman Sachs
Portfolio at the public offering price, which may include a sales charge, un-
less a sales charge has previously been paid on the investment represented by
the exchanged units (i.e., the units to be exchanged were originally issued in
exchange for shares on which a sales charge was paid), in which case the auto-
matic exchanges will be made at net asset value. In the case of ILA Class B
Unitholders, such exchanges will be made into the relevant Goldman Sachs Port-
folio at net asset value and will be subject to the CDSC of the original shares
held. For purposes of determining the amount of any applicable CDSC, the length
of time a unitholder has owned ILA Class B Units will be measured from the date
the unitholder acquired the original Class B shares and will not be affected by
any subsequent exchange. Investors should consult their Goldman Sachs Portfolio
Class B shares prospectus to determine the amount of their applicable CDSC.
Dividends and/or capital gains of ILA Service Units of each Portfolio and ILA
Class B Units of the Prime Obligations Portfolio which have been reinvested may
be exchanged for corresponding shares of a Goldman Sachs Portfolio without an
initial sales charge or CDSC. These automatic exchanges are made monthly on the
fifteenth day of each month or the first Business Day thereafter and are sub-
ject to the following conditions. The mini-     
 
                                       22
<PAGE>
 
mum dollar amount for automatic exchanges must be at least $50 per month. At
the time the election is made (i) the value of the unitholder's account in the
Portfolio from which the exchange is made must equal or exceed $10,000 and (ii)
the value of the account in the acquired fund must equal or exceed the acquired
fund's minimum initial investment requirement or, if the unitholder has elected
the automatic exchange privilege and the value of the acquired fund does not
equal the acquired fund's minimum, such election must continue until the mini-
mum initial investment requirement is met. The names, addresses and social se-
curity or taxpayer identification numbers for the unitholder accounts with the
exchanged and acquired funds must be identical. A unitholder should obtain and
read the prospectus relating to any Goldman Sachs Portfolio and its shares and
consider its investment objective, policies and applicable fees and expenses
before electing an automatic exchange into that Goldman Sachs Portfolio.
 
                                   EXCHANGES
     
  ILA Service Units of each Portfolio and ILA Class B Units of the Prime Obli-
gations Portfolio may be exchanged for the corresponding shares of any Goldman
Sachs Portfolio. A unitholder should obtain and read the prospectus for the
relevant Goldman Sachs Portfolio and consider its investment objectives, poli-
cies and applicable fees before making an exchange. Exchanges of ILA Service
Units from each Portfolio will be made into the relevant Goldman Sachs Port-
folio at the public offering price, which may include a sales charge, unless a
sales charge has previously been paid on the investment represented by the ex-
changed units (i.e., the units to be exchanged were originally issued in ex-
change for shares on which a sales charge was paid), in which case the exchange
will be made at net asset value. In the case of ILA Class B Unitholders, such
exchanges will be made into the relevant Goldman Sachs Portfolio at net asset
value and will be subject to the CDSC of the original shares held. For purposes
of determining the amount of any applicable CDSC, the length of time a
unitholder has owned ILA Class B Units will be measured from the date the
unitholder acquired the original Class B shares and will not be affected by any
subsequent exchange. Investors should consult their Goldman Sachs Portfolio
Class B shares prospectus to determine the amount of their applicable CDSC. ILA
Service Units of each Portfolio or ILA Class B Units of the Prime Obligations
Portfolio purchased through dividend and/or capital gains reinvestment may be
exchanged for corresponding shares of a Goldman Sachs Portfolio without an ini-
tial sales charge or CDSC.     
 
  An exchange may be made by contacting an Authorized Dealer or writing to
Goldman Sachs Money Market Trust, c/o NFDS, P.O. Box 419711, Kansas City, MO
64141-6711 or, if previously elected on the Account Information Form, by tele-
phone at 1-800-526-7384 (9:00 a.m. to 4:00 p.m. New York time). Under the tele-
phone exchange privilege, units may be exchanged among accounts with different
names, addresses or social security or taxpayer identification numbers only if
the exchange request is in writing and is received in accordance with the pro-
cedures set forth under "Redemption of Units."
 
  In addition to free automatic exchanges pursuant to the Automatic Exchange
Program, six free exchanges are permitted in each twelve-month period. It may
be difficult to implement the telephone exchange privilege in times of drastic
economic or market changes. In an effort to prevent unauthorized or fraudulent
exchange requests by telephone, Goldman Sachs employs reasonable procedures as
set forth under "Redemption of Units" to confirm that such instructions are
genuine. All exchanges are subject to the minimum investment requirements of
the Portfolio or Goldman Sachs Portfolio into which the shares or units are be-
ing exchanged. The minimum initial exchange for shareholders of a Goldman Sachs
Portfolio is $10,000 or the full account share balance, whichever is less.
 
  An exchange fee may be imposed or the exchange privilege may be modified or
withdrawn at any time upon 60 days' notice to unitholders. The
 
                                       23
<PAGE>
 
Trust, the relevant fund or Goldman Sachs may reject or restrict purchases of
units or shares by a particular purchaser or group, for example, when a pattern
of frequent purchases and sales of units or shares is evident or if the pur-
chase and sale orders are, or a subsequent abrupt redemption might be, of a
size that would disrupt management of a Portfolio or a Goldman Sachs Portfolio.
Exchanges are available only in states where the exchange may be legally made.
 
                              REDEMPTION OF UNITS
 
HOW TO REDEEM
 
  ILA Service Units may be redeemed through Goldman Sachs acting as a Service
Organization as specified below.
 
    
  ILA Service Units of a Portfolio may be redeemed without charge upon request
on any Business Day at the net asset value next determined after receipt by
State Street as agent for Goldman Sachs, as a Service Organization, of the re-
demption request. ILA Class B Units of the Prime Obligations Portfolio may be
redeemed without charge upon request on any Business Day at the net asset value
next determined after receipt of the redemption request less any applicable
CDSC. Investors should consult their Goldman Sachs Portfolio Class B shares
prospectus to determine the amount, if any, of the CDSC at the time of redemp-
tion. Redemption requests may be made by contacting Goldman Sachs or, if units
are held in a "street name" account, the applicable Authorized Dealer. Written
requests may be addressed to Goldman Sachs Money Market Trust, c/o NFDS, P.O.
Box 419711, Kansas City, MO 64141-6711. A unitholder may request redemptions by
telephone only if the optional telephone redemption privilege has been elected
on the Account Information Form. It may be difficult to implement redemptions
by telephone in times of drastic economic or market changes.     
 
  In an effort to prevent unauthorized or fraudulent redemption requests by
telephone, Goldman Sachs and NFDS each employ reasonable procedures specified
by the Trust to confirm that such instructions are genuine. Consequently, pro-
ceeds of telephone redemption requests will only be sent to the unitholder's
address of record or authorized bank account designated in the Account Informa-
tion Form and exchanges of units will only be made to an identical account.
Telephone requests may also be recorded. The Trust may implement other proce-
dures from time to time. If reasonable procedures are not implemented, the
Trust may be liable for any loss due to unauthorized or fraudulent transac-
tions. In all other cases, neither the Portfolios, the Trust nor Goldman Sachs
will be responsible for the authenticity of instructions received by telephone.
Proceeds of telephone redemptions will be mailed to the unitholder's address of
record or wired to the authorized bank account indicated on the Account Infor-
mation Form, unless the unitholder provides written instructions (accompanied
by a signature guarantee) indicating another address.
 
  Written requests for redemptions must be signed by each unitholder with its
signature guaranteed by a bank, a securities broker or dealer, a credit union
having authority to issue signature guarantees, a savings and loan association,
a building and loan association, a cooperative bank, a federal savings bank or
association, a national securities exchange, a registered securities associa-
tion or a clearing agency, provided that such institution satisfies the stan-
dards established by the Transfer Agent.

  After a wire has been initiated by Goldman Sachs, neither Goldman Sachs nor
the Trust assumes any further responsibility for the performance of intermedi-
aries or the customer's Service Organization in the transfer process. If a
problem with such performance arises, the customer should deal directly with
such intermediaries or Service Organization.
 
    
CHECK REDEMPTION PRIVILEGE (ILA SERVICE UNITS ONLY)     
 
  Goldman Sachs or its agent, as a record holder of ILA Service Units of a
Portfolio, may elect to have a special account with State Street for the pur-
pose of permitting its customers to redeem ILA Service Units from their ac-
counts in each Portfolio by check. When State Street receives a completed ap-
plication form, Goldman Sachs or its agent, as a record holder of the ILA Serv-
ice Units, will forward to the requesting customer a supply of checks. Checks
drawn on this account may be payable to the order of any person in any amount
of $500 or more, but cannot be certified. The payee of the check may cash or
deposit it like any other check drawn on a bank. When such a check is presented
to State Street for payment, a sufficient number of full and fractional ILA
Service Units will be redeemed to cover the amount of the check. Cancelled
checks will be returned to the record holder of ILA Service Units by State
Street.
 
  The check redemption privilege enables a unitholder to receive the dividends
declared on the ILA Service Units to be redeemed until such time as the check
is processed. Because of this feature,
 
                                       25
<PAGE>
 
the check redemption privilege may not be used for a complete liquidation of a
unitholder's account. If the amount of a check is greater than the value of the
ILA Service Units held in the unitholder's account, the check will be returned
unpaid, and the unitholder may be subject to extra charges.
 
  Goldman Sachs reserves the right to impose conditions on, limit the avail-
ability of or terminate the check redemption privilege at any time with respect
to a particular unitholder or all unitholders in general. The Trust and State
Street reserve the right at any time to suspend the procedure permitting re-
demptions by check and intend to do so in the event that federal legislation or
regulations impose reserve requirements or other restrictions deemed by the
Trustees to be adverse to the interests of other ILA Service Unitholders of the
Portfolios.
 
                                NET ASSET VALUE
     
  The net asset value of ILA Service Units of each Portfolio and ILA Class B
Units of Prime Obligations Portfolio is determined as of the close of regular
trading on the New York Stock Exchange (normally 4:00 P.M. New York time) on
each Business Day. Net asset value per unit for each class of units of each
Portfolio is calculated by determining the amount of net assets attributable to
each class of units and dividing by the number of units for such class.     
 
  On any Business Day, as defined herein, when the Public Securities Associa-
tion (PSA) recommends that the securities markets close early, the Prime Obli-
gations Portfolio and Tax-Exempt Diversified Portfolio reserve the right to
cease, accepting purchase and redemption orders for same Business Day credit at
the time the PSA recommends that the securities markets close. On days either
Portfolio closes early, purchase and redemption orders received after the PSA
recommended closing time will be credited for the next Business Day. In addi-
tion, each Portfolio reserves the right to advance the time by which purchase
and redemption orders must be received for same Business Day credit as permit-
ted by the SEC.
 
  Each Portfolio's portfolio securities are valued at their amortized cost,
which does not take into account unrealized securities gains or losses. This
method involves initially valuing an instrument at its cost and thereafter as-
suming a constant amortization to maturity of any premium paid or discount re-
ceived.
 
                               YIELD INFORMATION
 
  From time to time, each Portfolio may advertise its yield and effective
yield. The yield of a Portfolio refers to the income generated by an investment
in the Portfolio over a seven-day period (which period will be stated in the
advertisement). 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 Portfolio is assumed to be reinvested. The effective
yield will be slightly higher than the yield because of the compounding effect
of this assumed reinvestment.
 
  The Tax-Exempt Diversified Portfolio may also quote tax-equivalent yield. The
Portfolio's tax-equivalent yield is calculated by determining the rate of re-
turn that would have to be achieved on a fully taxable investment to produce
the after-tax equivalent of the Portfolio's yield, assuming certain tax brack-
ets for a unitholder.
 
  Investors should note that the investment results of a Portfolio are based on
historical performance and will fluctuate over time. Any presentation of a
Portfolio's yield, effective yield or tax-equivalent yield for any prior period
should not be considered a representation of what an investment may earn or
what a Portfolio's yield, effective yield or tax-equivalent yield may be in any
future period.
     
  Yield, effective yield and tax-equivalent yield will be calculated separately
for ILA Service Units, ILA Units, ILA Administration Units and ILA Class B
Units. Because each such class of units is subject to different expenses, the
net yield of such     
 
                                       26
<PAGE>
 
classes of a Portfolio for the same period may differ. See "Organization and
Units of the Portfolios" below.
 
                    ORGANIZATION AND UNITS OF THE PORTFOLIOS
     
  The Trust was formed as a business trust under the laws of The Commonwealth
of Massachusetts on December 6, 1978. The Trustees of the Trust are responsible
for the overall management and supervision of its affairs. The Declaration of
Trust further authorizes the Trustees to classify or reclassify any series or
portfolio of units into one or more classes. The Trustees have authorized the
issuance of three classes of units of the Tax-Exempt Diversified Portfolio and
four classes of units of the Prime Obligations Portfolio, which are: ILA Units,
ILA Administration Units and ILA Service Units and in the case of the Prime Ob-
ligations Portfolio, ILA Class B Units.     
 
  When issued, units are fully paid and nonassessable by the Trust. In the
event of liquidation, unitholders are entitled to share pro rata in the net as-
sets of the applicable Portfolio available for distribution to unitholders.
Units entitle their holders to one vote per unit, are freely transferable and
have no preemptive, subscription or conversion rights.
 
  Units of a Portfolio will be voted separately by Portfolio with respect to
matters pertaining to that Portfolio except for the election of Trustees and
ratification of independent accountants. For example, unitholders of each Port-
folio are required to approve the adoption of any investment advisory agreement
relating to that Portfolio and any changes in fundamental investment restric-
tions or policies of such Portfolio. Approval by the unitholders of one Portfo-
lio is effective only as to that Portfolio.

  The Trust does not intend to hold annual unitholder meetings, although spe-
cial meetings may be called for such purposes as electing or removing Trustees,
complying with a requirement of the Investment Company Act, or such other pur-
poses as are set forth above. The Trust will facilitate unitholder communica-
tion as required and in the manner prescribed by Section 16(c) of the Invest-
ment Company Act.

                                   APPENDIX A
 
 GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON ACCOUNT IN-
                                 FORMATION FORM
 
  You are required by law to provide the Portfolio in which you invest with
your correct Social Security or Taxpayer Identification Number (TIN), regard-
less of whether you file tax returns. Failure to do so may subject you to pen-
alties. Failure to provide your correct TIN, to check the appropriate boxes,
and to sign your name in the Social Security Number or other Taxpayer Identifi-
cation Number Certification section (the "Certification Section") of the Ac-
count Information Form, could result in withholding of 31% by the Portfolio for
the federal backup withholding tax on distributions, redemptions, exchanges and
other payments relating to your account. However, distributions will not be
subject to backup withholding if a Portfolio reasonably estimates that at least
95% of its distributions will be exempt-interest dividends, and redemptions and
exchanges will not be subject to backup withholding if the Portfolio success-
fully maintains a constant $1.00 net asset value per unit. Each Portfolio re-
serves the right to refuse to open an account for, or to close the account of,
any investor who fails to (1) provide a TIN, or (2) certify that such TIN is
correct (if required to do so under applicable law) in establishing an account.
 
  Any tax withheld may be credited against taxes owed on your federal income
tax return.
 
  Special rules apply for certain entities. For example, for an account estab-
lished under a Uniform Gifts or Transfers to Minors Act, the TIN of the minor
should be furnished.
 
  If you do not have a TIN, you should apply for one immediately by contacting
your local office of the Social Security Administration or the Internal Revenue
Service (IRS). If you do not have a TIN but have applied for or intend to apply
for one, you should check the first box in the Certification Section. In this
event, you should provide your TIN and required certifications within 60 days.
If you do not provide your TIN and required certification within 60 days, 31%
backup withholding may apply. Backup withholding could also apply to payments
relating to your account prior to the Portfolio's receipt of your TIN and re-
quired certifications.
 
  If you have been notified by the IRS that you are subject to backup withhold-
ing because you failed to report all your interest and/or dividend income on
your tax return and you have not been notified by the IRS that such withholding
should cease, you must cross out item (2) in the Certification Section.
 
  If you are an exempt recipient, you should furnish your TIN and check the
second box in the Certification Section. Exempt recipients include
corporations, tax-exempt pension plans and IRA's, governmental agencies,
financial institutions, registered securities and commodities dealers and
others.
 
  If you are a nonresident alien or foreign entity, check the third box in the
Certification Section and provide a completed Form W-8 to the Portfolio in or-
der to avoid backup withholding on certain payments. Other payments to you may
be subject to nonresident alien withholding of up to 30%.
 
  For further information regarding backup and nonresident alien withholding,
see Sections 3406, 1441, and 1442 of the Internal Revenue Code and consult your
tax adviser.

                       INVESTMENT POLICIES AND PRACTICES
                               OF THE PORTFOLIOS


      The following discussion elaborates on the description of each Portfolios'
investment policies and practices contained in the Prospectus:

U.S. GOVERNMENT SECURITIES

      Each Portfolio may invest in separately traded principal and interest
components of securities issued or guaranteed by the U.S. Treasury.  The
principal and interest components of selected securities are traded
independently under the Separate Trading of Registered Interest and Principal of
Securities program ("STRIPS").  Under the STRIPS program, the principal and
interest components are individually numbered and separately issued by the U.S.
Treasury at the request of depository financial institutions, which then trade
the component parts independently.

CUSTODIAL RECEIPTS

      Each Portfolio (other than Treasury Obligations Portfolio, Treasury
Instruments Portfolio, Federal Portfolio and Government Portfolio) may also
acquire custodial receipts that evidence ownership of future interest payments,
principal payments or both on certain U.S. Government notes or bonds.  Such
notes and bonds are held in custody by a bank on behalf of the owners.  These
custodial receipts are known by various names, including "Treasury Receipts,"
"Treasury Investors Growth Receipts" ("TIGR's"), and "Certificates of Accrual on
Treasury Securities" ("CATS").  Although custodial receipts are not considered
U.S. Government Securities for certain securities law purposes, they are
indirectly issued or guaranteed as to principal and interest by the U.S.
Government, its agencies, authorities or instrumentalities.

BANK AND CORPORATE OBLIGATIONS

      Commercial paper represents short-term unsecured promissory notes issued
in bearer form by banks or bank holding companies, corporations, and finance
companies.  The commercial paper purchased by the Portfolios consists of direct
U.S. dollar denominated obligations of domestic or, in the case of Money Market
Portfolio, foreign issuers.  Bank obligations in which the Portfolios may invest
include certificates of deposit, bankers' acceptances, fixed time deposits and
bank notes.  Certificates of deposit are negotiable certificates issued against
funds deposited in a commercial bank for a definite period of time and earning a
specified return.

                                       4
<PAGE>
 
      Bankers' acceptances are negotiable drafts or bills of exchange, normally
drawn by an importer or exporter to pay for specific merchandise, which are
"accepted" by a bank, meaning, in effect, that the bank unconditionally agrees
to pay the face value of the instrument on maturity.  Fixed time deposits are
bank obligations payable at a stated maturity date and bearing interest at a
fixed rate.  Fixed time deposits may be withdrawn on demand by the investor, but
may be subject to early withdrawal penalties which vary depending upon market
conditions and the remaining maturity of the obligation.  There are no
contractual restrictions on the right to transfer a beneficial interest in a
fixed time deposit to a third party, although there is no market for such
deposits.  Bank notes and bankers acceptances rank junior to domestic deposit
liabilities of the bank and  pari passu with other senior, unsecured obligations
of the bank.  Bank notes are not insured by the Federal Deposit Insurance
Corporation or any other insurer.  Deposit notes are insured by the Federal
Deposit Insurance Corporation only to the extent of $100,000 per depositor per
bank.

      The Prime Obligations Portfolio and Money Market Portfolio may invest in
funding agreements.  A funding agreement is a contract between an issuer and a
purchaser that obligates the issuer to pay a guaranteed rate of interest on a
principal sum deposited by the purchaser.  Funding agreements will also
guarantee the return of principal and may guarantee a stream of payments over
time.  A funding agreement has a fixed maturity date and may have either a fixed
rate or variable interest rate that is based on an index and guaranteed for a
set time period.  Because there is no secondary market for these investments,
any such funding agreement purchased by a Portfolio will be regarded as
illiquid.

REPURCHASE AGREEMENTS

      Each Portfolio (other than the Treasury Instruments Portfolio) may enter
into repurchase agreements with selected broker-dealers, banks or other
financial institutions.  A repurchase agreement is an arrangement under which
the purchaser (i.e., the Portfolio) purchases a U.S. Government security or
other high quality short-term debt obligation (the "Obligation") and the seller
agrees, at the time of sale, to repurchase the Obligation at a specified time
and price.

      Custody of the Obligation will be maintained by the Portfolios' custodian
or subcustodian.  The repurchase price may be higher than the purchase price,
the difference being income to the Portfolio, or the purchase and repurchase
prices may be the same, with interest at a stated rate due to the Portfolio
together with the repurchase price on repurchase.  In either case, the income to
the Portfolio is unrelated to the interest rate on the Obligation subject to the
repurchase agreement.

                                       5
<PAGE>
 
      Repurchase agreements pose certain risks for all entities, including the
Portfolios, that utilize them.  Such risks are not unique to the Portfolios but
are inherent in repurchase agreements.  The portfolios seek to minimize such
risks by, among others, the means indicated below, but because of the inherent
legal uncertainties involved in repurchase agreements, such risks cannot be
eliminated.

      For purposes of the Investment Company Act of 1940, as amended (the
"Investment Company Act"), and for federal income tax purposes, a repurchase
agreement is deemed to be a loan from the Portfolio to the seller of the
Obligation.  It is not clear whether for other purposes a court would consider
the Obligation purchased by the Portfolio subject to a repurchase agreement as
being owned by the Portfolio or as being collateral for a loan by the Portfolio
to the seller.

      If in the event of bankruptcy or insolvency proceedings against the seller
of the Obligation, a court holds that the Portfolio does not have a perfected
security interest in the Obligation, the Portfolio may be required to return the
Obligation to the seller's estate and be treated as an unsecured creditor of the
seller.  As an unsecured creditor, a Portfolio would be at risk of losing some
or all of the principal and income involved in the transaction.  To minimize
this risk, the Portfolios utilize custodians and subcustodians that the Adviser
believes follow customary securities industry practice with respect to
repurchase agreements, and the Adviser analyzes the creditworthiness of the
obligor, in this case the seller of the Obligation.  But because of the legal
uncertainties, this risk, like others associated with repurchase agreements,
cannot be eliminated.

      Also, in the event of commencement of bankruptcy or insolvency proceedings
with respect to the seller of the Obligation before repurchase of the Obligation
under a repurchase agreement, the Portfolio may encounter delay and incur costs
before being able to sell the security.   Such a delay may involve loss of
interest or a decline in price of the Obligation.

      Apart from risks associated with bankruptcy or insolvency proceedings,
there is also the risk that the seller may fail to repurchase the security.
However, if the market value of the Obligation subject to the repurchase
agreement becomes less than the repurchase price (including accrued interest),
the Portfolio will direct the seller of the Obligation to deliver additional
securities so that the market value of all securities subject to the repurchase
agreement equals or exceeds the repurchase price.

      Certain repurchase agreements which mature in more than seven days can be
liquidated before the nominal fixed term on

                                       6
<PAGE>
 
seven days or less notice.  Such repurchase agreements will be regarded as
liquid instruments.

      In addition, the Fund, together with other registered investment companies
having advisory agreements with the Adviser or any of its affiliates, may
transfer uninvested cash balances into a single joint account, the daily
aggregate balance of which will be invested in one or more repurchase
agreements.

FOREIGN SECURITIES

      The Money Market Portfolio may invest in foreign securities and in
certificates of deposit, bankers' acceptances and fixed time deposits and other
obligations issued by major foreign banks, foreign branches of U.S. banks, U.S.
branches of foreign banks and foreign branches of foreign banks.  Investments
can include fixed time deposits in Cayman Island branches of such banks.  The
Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York Portfolios
may also invest in municipal instruments backed by letters of credit issued by
certain of such banks.  Under current Securities and Exchange Commission ("SEC")
rules relating to the use of the amortized cost method of portfolio securities
valuation, the Money Market Portfolio is restricted to purchasing U.S. dollar
denominated securities, but it is not otherwise precluded from purchasing
securities of foreign issuers.

      Investments in foreign securities and bank obligations may involve
considerations different from investments in domestic securities due to limited
publicly available information; non-uniform accounting standards; the possible
imposition of withholding or confiscatory taxes; the possible adoption of
foreign governmental restrictions affecting the payment of principal and
interest; expropriation; or other adverse political or economic developments.
In addition, it may be more difficult to obtain and enforce a judgment against a
foreign issuer or a foreign branch of a domestic bank.

ASSET-BACKED AND RECEIVABLES-BACKED SECURITIES

      The Money Market Portfolio may invest up to 5% of its net assets in asset-
backed and receivables-backed securities.  Asset-backed and receivables-backed
securities represent participations in, or are secured by and payable from,
pools of assets such as motor vehicle installment sale contracts, installment
loan contracts, leases of various types of real and personal property,
receivables from revolving credit (credit card) agreements, corporate
receivables and other categories of receivables.  Such asset pools are
securitized through the use of privately-formed trusts or special purpose
vehicles.  Payments or distributions of principal and interest may be guaranteed
up to certain amounts and for a certain time period by a letter of credit or a
pool

                                       7
<PAGE>
 
insurance policy issued by a financial institution or other credit enhancements
may be present.  The value of a Portfolio's investments in asset-backed and
receivables-backed securities may be adversely affected by prepayment of the
underlying obligations.  In addition, the risk of prepayment may cause the value
of these investments to be more volatile than a Portfolio's other investments.

      Through the use of trusts and special purpose corporations, various types
of assets, including automobile loans, computer leases, trade receivables and
credit card receivables, are being securitized in pass-through structures
similar to the mortgage pass-through structures.  Consistent with its investment
objectives and policies, the Money Market Portfolio may invest up to 5% of its
net assets in these and other types of asset-backed securities that may be
developed in the future.  However, the Portfolio will generally not invest in an
asset-backed security if the income received with respect to its investment
constitutes rental income or other income not treated as qualifying income under
the 90% test described in "Tax Information" below.  In general, the collateral
supporting these securities is of shorter maturity than mortgage loans and is
less likely to experience substantial prepayments in response to interest rate
fluctuations.  The Money Market Portfolio may invest in new types of asset-
backed securities that may be developed in the future to the extent consistent
with its investment objective and policies.  This Statement of Additional
Information will be amended or supplemented as necessary to reflect the Money
Market Portfolio's intention to invest in asset-backed securities with
characteristics that are materially different from the securities described in
the preceding paragraph.

      As set forth below, several types of asset-backed and receivables-backed
securities have already been offered to investors, including for example,
Certificates for Automobile Receivables/sm/ ("CARS/sm/") and interests in pools
of credit card receivables.  CARS/sm/ represent undivided fractional interests
in a trust ("CAR Trust") whose assets consist of a pool of motor vehicle retail
installment sales contracts and security interests in the vehicles securing the
contracts.  Payments of principal and interest on CARS/sm/ are passed through
monthly to certificate holders, and are guaranteed up to certain amounts and for
a certain time period by a letter of credit issued by a financial institution
unaffiliated with the trustee or originator of the CAR Trust.  An investor's
return on CARS/sm/ may be affected by early prepayment of principal on the
underlying vehicle sales contracts.  If the letter of credit is exhausted, the
CAR Trust may be prevented from realizing the full amount due on a sales
contract because of state law requirements and restrictions relating to
foreclosure sales of vehicles and the obtaining of deficiency judgments
following such sales or because of

                                       8
<PAGE>
 
depreciation, damage or loss of a vehicle, the application of federal and state
bankruptcy and insolvency laws, or other factors.  As a result, certificate
holders may experience delays in payments or losses if the letter of credit is
exhausted.

      Asset-backed securities present certain risks that are not presented by
mortgage-backed securities.  Primarily, these securities may not have the
benefit of any security interest in the related assets.  Credit card receivables
are generally unsecured and the debtors are entitled to the protection of a
number of state and federal consumer credit laws, many of which give such
debtors the right to set off certain amounts owed on the credit cards, thereby
reducing the balance due.  There is the possibility that recoveries on
repossessed collateral may not, in some cases, be available to support payments
on these securities.

      Asset-backed securities are often backed by a pool of assets representing
the obligations of a number of different parties.  To lessen the effect of
failures by obligors on underlying assets to make payments, the securities may
contain elements of credit support which fall into two categories:  (i)
liquidity protection, and (ii) protection against losses resulting from ultimate
default by an obligor or servicer.  Liquidity protection refers to the provision
of advances, generally by the entity administering the pool of assets, to ensure
that the receipt of payments on the losses results from payment of the insurance
obligations on at least a portion of the assets in the pool.  This protection
may be provided through guarantees, policies or letters of credit obtained by
the issuer or sponsor from third parties, through various means of structuring
the transactions or through a combination of such approaches.  The degree of
credit support provided for each issue is generally based on historical
information reflecting the level of credit risk associated with the underlying
assets.  Delinquency or loss in excess of that anticipated or failure of the
credit support could adversely affect the value of or return on an investment in
such a security.

      The availability of asset-backed securities may be affected by legislative
or regulatory developments.  It is possible that such developments could require
the Money Market Portfolio to dispose of any then existing holdings of such
securities.

FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES

      Each Portfolio may purchase securities on a when-issued basis or purchase
or sell securities on a forward commitment basis.  These transactions involve a
commitment by the Portfolio to purchase or sell securities at a future date.
The price of the underlying securities (usually expressed in terms of yield) and
the date when the securities will be delivered and paid for

                                       9
<PAGE>
 
(the settlement date) are fixed at the time the transaction is negotiated.
When-issued purchases and forward commitment transactions are negotiated
directly with the other party, and such commitments are not traded on exchanges,
but may be traded over-the-counter.

      A Portfolio will purchase securities on a when-issued basis or purchase or
sell securities on a forward commitment basis only with the intention of
completing the transaction and actually purchasing or selling the securities.
If deemed advisable as a matter of investment strategy, however, a Portfolio may
dispose of or negotiate a commitment after entering into it.  A Portfolio also
may sell securities it has committed to purchase before those securities are
delivered to the Portfolio on the settlement date.  The Portfolio may realize a
capital gain or loss in connection with these transactions.  For purposes of
determining a Portfolio's average dollar weighted maturity, the maturity of
when-issued or forward commitment securities will be calculated from the
commitment date.

      When a Portfolio purchases securities on a when-issued or forward
commitment basis, the Portfolio's custodian or subcustodian will maintain in a
segregated account cash or liquid, high grade debt securities having a value
(determined daily) at least equal to the amount of the Portfolio's purchase
commitments.  In the case of a forward commitment to sell portfolio securities
subject to such commitment, the custodian or subcustodian will hold the
portfolio securities in a segregated account while the commitment is
outstanding.  These procedures are designed to ensure that the Portfolio will
maintain sufficient assets at all times to cover its obligations under when-
issued purchases and forward commitments.

VARIABLE AMOUNT MASTER DEMAND NOTES

      Each Portfolio (other than the Treasury Obligations and Treasury
Instruments Portfolios) may purchase variable amount master demand notes.  These
obligations permit the investment of fluctuating amounts at varying rates of
interest pursuant to direct arrangements between a Portfolio, as lender, and the
borrower.  Variable amount master demand notes are direct lending arrangements
between the lender and borrower and are not generally transferable, nor are they
ordinarily rated.  A Portfolio may invest in them only if the Adviser believes
that the notes are of comparable quality to the other obligations in which that
Portfolio may invest.

VARIABLE RATE AND FLOATING RATE DEMAND INSTRUMENTS

      Each Portfolio (other than the Treasury Obligations and Treasury
Instruments Portfolios) may purchase variable and floating rate demand
instruments that are tax exempt municipal

                                       10
<PAGE>
 
obligations or other debt securities that possess a floating or variable
interest rate adjustment formula.  These instruments permit a Portfolio to
demand payment of the principal balance plus unpaid accrued interest upon a
specified number of days' notice to the issuer or its agent.  The demand feature
may be backed by a bank letter of credit or guarantee issued with respect to
such instrument.

      The terms of the variable or floating rate demand instruments that a
Portfolio may purchase provide that interest rates are adjustable at intervals
ranging from daily up to six months, and the adjustments are based upon current
market levels, the prime rate of a bank or other appropriate interest rate
adjustment index as provided in the respective instruments.  Some of these
instruments are payable on demand on a daily basis or on not more than seven
days' notice.   Others, such as instruments with quarterly or semiannual
interest rate adjustments, may be put back to the issuer on designated days on
not more than thirty days' notice.  Still others are automatically called by the
issuer unless the Portfolio instructs otherwise.  The Trust, on behalf of the
Portfolios, intends to exercise the demand only (1) upon a default under the
terms of the debt security, (2) as needed to provide liquidity to a Portfolio,
(3) to maintain the respective quality standards of a Portfolio's investment
portfolio, or (4) to attain a more optimal portfolio structure.  A Portfolio
will determine the variable or floating rate demand instruments that it will
purchase in accordance with procedures approved by the Trustees to minimize
credit risks.  Accordingly, any variable or floating rate demand instrument must
satisfy the Portfolio's credit criteria with respect to both its long-term and
short-term ratings, except that where credit support is provided, a Portfolio
may rely solely on short-term ratings of the variable or floating rate demand
instrument, i.e., the right to sell.  To be eligible for purchases by a
Portfolio, variable or floating rate demand instrument which is unrated must
have high quality characteristics similar to other obligations in which the
Portfolio may invest.  The Adviser may determine that an unrated variable or
floating rate demand instrument meets a Portfolio's quality criteria by reason
of being backed by a letter of credit or guarantee issued by a bank that meets
the quality criteria for the Portfolio.  Thus, either the credit of the issuer
of the obligation or the guarantor bank or both will meet the quality standards
of the Portfolio.

      The maturity of the variable or floating rate demand instruments held by a
Portfolio will ordinarily be deemed to be the longer of (1) the notice period
required before the Portfolio is entitled to receive payment of the principal
amount of the instrument or (2) the period remaining until the instrument's next
interest rate adjustment.  The acquisition of variable or floating rate demand
notes for a Portfolio must also meet the

                                       11
<PAGE>
 
requirements of rules issued by the SEC applicable to the use of the amortized
cost method of securities valuation.

      A Portfolio (other than Treasury Obligations Portfolio, Treasury
Instruments Portfolio, Government Portfolio and Federal Portfolio) may invest in
participation interests in variable or floating rate tax-exempt obligations held
by financial institutions (usually commercial banks).  Such participation
interests provide the Portfolio with a specific undivided interest (up to 100%)
in the underlying obligation and the right to demand payment of its proportional
interest in the unpaid principal balance plus accrued interest from the
financial institution upon a specific number of day's notice.  In addition, the
participation interest generally is backed by an irrevocable letter of credit or
guarantee from the institution.  The financial institution usually is entitled
to a fee for servicing the obligation and providing the letter of credit.

RESTRICTED AND OTHER ILLIQUID SECURITIES

      A Portfolio may purchase securities that are not registered ("restricted
securities") under the Securities Act of 1933 ("1933), including restricted
securities that can be offered and sold to "qualified institutional buyers"
under Rule 144A under the 1933 Act.  However, a Portfolio will not invest more
than 10% of the value of its net assets in securities which are illiquid, which
includes fixed time deposits and repurchase agreements maturing in more than
seven days that cannot be traded on a secondary market and restricted
securities, unless, in the case of restricted securities,  the Trust's Board of
Trustees determines, based upon a continuing review of the trading markets for
the specific restricted security, that such restricted securities are liquid.
The Board of Trustees may adopt guidelines and delegate to the Adviser the daily
function of determining and monitoring liquidity of restricted securities.  The
Board, however, will retain sufficient oversight and be ultimately responsible
for the determinations.  Since it is not possible to predict with assurance that
the market for securities eligible for resale under Rule 144A will continue to
be liquid, the Board will carefully monitor each Portfolio's investments in
these securities, focusing on such important factors, among others, as
valuation, liquidity and availability of information.  This investment practice
could have the effect of increasing the level of illiquidity in a Portfolio to
the extent that qualified institutional buyers become for a time uninterested in
purchasing these restricted securities.

MUNICIPAL OBLIGATIONS

      The Prime Obligations, Money Market, Tax-Exempt Diversified, Tax-Exempt
California and Tax-Exempt New York Portfolios may invest in municipal
obligations.  Municipal

                                       12
<PAGE>
 
obligations are issued by or on behalf of states, territories and possessions of
the United States and their political subdivisions, agencies, authorities and
instrumentalities and the District of Columbia to obtain funds for various
public purposes.  The interest on most of these obligations is generally exempt
from regular federal income tax.  The two principal classifications of municipal
obligations are "notes" and "bonds".

      Notes.   Municipal notes are generally used to provide for short-term
capital needs and generally have maturities of one year or less.  Municipal
notes include tax anticipation notes, revenue anticipation notes, bond
anticipation notes, tax and revenue anticipation notes, construction loan notes,
tax-exempt commercial paper and certain receipts for municipal obligations.

      Tax anticipation notes are sold to finance working capital needs of
municipalities.  They are generally payable from specific tax revenues expected
to be received at a future date.  They are usually general obligations of the
issuer, secured by the taxing power for payment of principal and interest.
Revenue anticipation notes are issued in expectation of receipt of other types
of revenue such as federal revenues available under the Federal Revenue Sharing
Program.  Tax anticipation notes and revenue anticipation notes are generally
issued in anticipation of various seasonal revenues such as income, sales, use,
and business taxes.  Bond anticipation notes are sold to provide interim
financing in anticipation of long-term financing in the market.  In most cases,
these monies provide for the repayment of the notes.  Construction loan notes
are sold to provide construction financing.  These notes are secured by mortgage
notes insured by the Federal Housing Authority; however, the proceeds from the
issuance may be less than the economic equivalent of the payment of principal
and interest on the mortgage note if there had been a default.  Tax-exempt
commercial paper consists of short-term unsecured promissory notes issued by a
state or local government or an authority or agency thereof.  The Portfolios
which invest in municipal obligations may also acquire securities in the form of
custodial receipts which evidence ownership of future interest payments,
principal payments or both on certain state and local governmental and authority
obligations when, in the opinion of bond counsel, interest payments with respect
to such custodial receipts are excluded from gross income for federal income tax
purposes, and in the case of the Tax-Exempt California and Tax-Exempt New York
Portfolios, exempt from California and New York (city and state) personal income
taxes, respectively.  Such obligations are held in custody by a bank on behalf
of the holders of the receipts.  These custodial receipts are known by various
names, including "Municipal Receipts" ("MRs") and "Municipal Certificates of
Accrual on Tax-Exempt Securities" ("M-CATS").  There are a number of other types
of notes issued for different purposes and secured differently from those
described above.

                                       13
<PAGE>
 
      Bonds.  Municipal bonds, which generally meet longer term capital needs
and have maturities of more than one year when issued, have two principal
classifications, "general obligation" bonds and "revenue" bonds.

      General obligation bonds are issued by entities such as states, counties,
cities, towns and regional districts and are used to fund a wide range of public
projects including the construction or improvement of schools, highways and
roads, water and sewer systems and a variety of other public purposes.   The
basic security of general obligation bonds is the issuer's pledge of its faith,
credit, and taxing power for the payment of principal and interest.  The taxes
that can be levied for the payment of debt service may be limited or unlimited
as to rate or amount or special assessments.

      Revenue bonds have been issued to fund a wide variety of capital projects
including:  electric, gas, water and sewer systems; highways, bridges and
tunnels; port and airport facilities; colleges and universities; and hospitals.
The principal security for a revenue bond is generally the net revenues derived
from a particular facility or group of facilities or, in some cases, from the
proceeds of a special excise or other specific revenue source.  Although the
principal security behind these bonds varies widely, many provide additional
security in the form of a debt service reserve fund whose monies may also be
used to make principal and interest payments on the issuer's obligations.
Housing finance authorities have a wide range of security including partially or
fully insured, rent subsidized and/or collateralized mortgages, and/or the net
revenues from housing or other public projects.  In addition to a debt service
reserve fund, some authorities provide further security in the form of a state's
ability (without obligation) to make up deficiencies in the debt service reserve
fund.  Lease rental revenue bonds issued by a state or local authority for
capital projects are secured by annual lease rental payments from the state or
locality to the authority sufficient to cover debt service on the authority's
obligations.

      Private activity bonds (a term that includes certain types of bonds the
proceeds of which are used to a specified extent for the benefit of persons
other than governmental units), although nominally issued by municipal
authorities, are generally not secured by the taxing power of the municipality
but are secured by the revenues of the authority derived from payments by the
industrial user.  The Tax-Exempt Diversified Portfolio and the Tax-Exempt
California Portfolio do not intend to invest in private activity bonds if the
interest from such bonds would be an item of tax preference to unitholders under
the federal alternative minimum tax.

                                       14
<PAGE>
 
      Municipal bonds with a series of maturity dates are called serial bonds.
The serial bonds which the Portfolios may purchase are limited to short-term
serial bonds---those with original or remaining maturities of thirteen months or
less.  The Portfolios may purchase long-term bonds provided that they have a
remaining maturity of thirteen months or less or, in the case of bonds called
for redemption, the date on which the redemption payment must be made is within
thirteen months.  The Portfolios may also purchase long-term bonds (sometimes
referred to as "Put Bonds"), which are subject to a Portfolio's commitment to
put the bond back to the issuer at par at a designated time within thirteen
months and the issuer's commitment to so purchase the bond at such price and
time.

      The Portfolios which invest in municipal obligations may invest in tender
option bonds.  A tender option bond is a municipal obligation (generally held
pursuant to a custodian arrangement) having a relatively long maturity and
bearing interest at a fixed rate substantially higher than prevailing short-term
tax-exempt rates.  The bond is typically issued in conjunction with the
agreement of a third party, such as a bank, broker-dealer or other financial
institutions, pursuant to which such institution grants the security holder the
option, at periodic intervals, to tender its securities to the institution and
receive the face value thereof.  As consideration for providing the option, the
financial institution receives periodic fees equal to the difference between the
bond's fixed coupon rate and the rate, as determined by a remarketing or similar
agent at or near the commencement of such period, that would cause the bond,
coupled with the tender option, to trade at par on the date of such
determination.  Thus, after payment of this fee, the security holder effectively
holds a demand obligation that bears interest at the prevailing short-term, tax-
exempt rate.  However, an institution will not be obligated to accept tendered
bonds in the event of certain defaults by, or a significant downgrading in the
credit rating assigned to, the issuer of the bond.

      The tender option will be taken into consideration in determining the
maturity of tender option bonds and the average portfolio maturity of a
Portfolio.  The liquidity of a tender option bond is a function of the credit
quality of both the bond issuer and the financial institution providing
liquidity.  Consequently, tender option bonds are deemed to be liquid unless, in
the opinion of the Adviser, the credit quality of the bond issuer and the
financial institution is deemed, in light of the relevant Portfolio's credit
quality requirements, to be inadequate.

      Although the Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt
New York Portfolios intend to invest in tender option bonds the interest on
which will, in the option of counsel for the issuer and sponsor or counsel
selected by the Adviser, be

                                       15
<PAGE>
 
excluded from gross income for federal income tax purposes, there is no
assurance that the Internal Revenue Service will agree with such counsel's
opinion in any particular case.  Consequently, there is a risk that a Portfolio
will not be considered the owner of such tender option bonds and thus will not
be entitled to treat such interest as exempt from such tax.  A similar risk
exists for certain other investments subject to puts or similar rights.
Additionally, the federal income tax treatment of certain other aspects of these
investments, including the proper tax treatment of tender options and the
associated fees, in relation to various regulated investment company tax
provisions is unclear.  The Tax-Exempt Diversified, Tax-Exempt California and
Tax-Exempt New York Portfolios intend to manage their respective portfolios in a
manner designed to eliminate or minimize any adverse impact from the tax rules
applicable to these investments.

      In addition to general obligation bonds, revenue bonds and serial bonds,
there are a variety of hybrid and special types of municipal obligations as well
as numerous differences in the security of municipal obligations both within and
between the two principal classifications above.

      The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
Portfolios may purchase municipal instruments that are backed by letters of
credit issued by foreign banks that have a branch, agency or subsidiary in the
United States.  Such letters of credit, like other obligations of foreign banks,
may involve credit risks in addition to those of domestic obligations, including
risks relating to future political and economic developments, nationalization,
foreign governmental restrictions such as exchange controls and difficulties in
obtaining or enforcing a judgment against a foreign bank (including branches).

      For the purpose of investment restrictions of the Portfolios, the
identification of the "issuer" of municipal obligations that are not general
obligation bonds is made by the Adviser on the basis of the characteristics of
the obligation as described above, the most significant of which is the source
of funds for the payment of principal of and interest on such obligations.

      An entire issue of municipal obligations may be purchased by one or a
small number of institutional investors such as one of the Portfolios.  Thus,
the issue may not be said to be publicly offered.  Unlike securities which must
be registered under the Securities Act of 1933 prior to offer and sale, unless
an exemption from such registration is available, municipal obligations which
are not publicly offered may nevertheless be readily marketable.  A secondary
market exists for municipal obligations which were not publicly offered
initially.

                                       16
<PAGE>
 
      Municipal obligations purchased for a Portfolio are subject to the policy
on holdings of securities which are not readily marketable contained in the
Portfolio's Prospectus.  The Adviser determines whether a municipal obligation
is liquid based on whether it may be sold in a reasonable time consistent with
the customs of the municipal markets (usually seven days) at a price (or
interest rate) which accurately reflects its value.  The Adviser believes that
the quality standards applicable to each Portfolio's investments enhance
liquidity.  In addition, stand-by commitments and demand obligations also
enhance liquidity.

      Yields on municipal obligations depend on a variety of factors, including
money market conditions, municipal bond market conditions, the size of a
particular offering, the maturity of the obligation and the quality of the
issue.  High grade municipal obligations tend to have a lower yield than lower
rated obligations.  Municipal obligations are subject to the provisions of
bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Code, and laws, if any, which may be
enacted by Congress or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations or municipalities to levy taxes.  There is also the
possibility that as a result of litigation or other conditions the power or
ability of any one or more issuers to pay when due principal of and interest on
its or their municipal obligations may be materially affected.

INVESTING IN CALIFORNIA

      The financial condition of the State of California ("California"), its
public authorities and local governments could affect the market values and
marketability of, and therefore the net asset value per unit and the interest
income of, the Tax-Exempt California Portfolio, or result in the default of
existing obligations, including obligations which may be held by the Tax-Exempt
California Portfolio.  The following section provides only a brief summary of
the complex factors affecting the financial condition of California, and is
based on information obtained from California, as publicly available prior to
the date of this Statement of Additional Information.  The information contained
in such publicly available documents has not been independently verified.  It
should be noted that the creditworthiness of obligations issued by local issuers
may be unrelated to the creditworthiness of California, and that there is no
obligation on the part of California to make payment on such local obligations
in the event of default in the absence of a specific guarantee or pledge
provided by California.

      California is experiencing significant financial difficulties, which have
reduced its credit standing.  The

                                       17
<PAGE>
 
ratings of certain related debt of other issuers for which California has an
outstanding lease purchase, guarantee or other contractual obligation (such as
for state-insured hospital bonds) are generally linked directly to California's
rating.  Should the financial condition of California deteriorate, its credit
ratings could be further reduced, and the market value and marketability of all
outstanding notes and bonds issued by California, its public authorities or
local governments could be adversely affected.

Economic Factors.  California's economy is the largest among the 50 states
- ----------------                                                          
(accounting for 13% of the nation's output of goods and services) and one of the
largest in the world.  California's population of more than 31 million
represents over 12% of the total United States population and grew by 27% in the
1980s.  While California's substantial population growth during the 1980's
stimulated local economic growth and diversification and sustained a real estate
boom between 1984 and 1990, it has increased strains on California's limited
water resources and demands for government services and may impede future
economic growth.  Population growth slowed between 1991 and 1993 even while
substantial immigration has continued, due to a significant increase in
outmigration by California residents.  Generally, the household incomes of new
residents have been substantially lower (and their education and welfare
utilization higher) than those of departing households, which may have a major
long-term socioeconomic and fiscal impact.  However, with the California economy
improving, the recent net outmigration within the Continental U.S. is expected
to decrease or be reversed.

      From mid-1990 to late 1993, California's economy suffered its worst
recession since the 1930s, with recovery starting later than for the nation as a
whole.  California has experienced the worst job losses of any post-war
recession.  Prerecession job levels may not be realized until near the end of
the decade.  The largest job losses have been in Southern California, led by
declines in the aerospace and construction industries.  Weakness statewide
occurred in manufacturing, construction, services and trade.  Additional
military base closures will have further adverse effects on California's economy
later in the decade.

      Since the start of 1994, the California economy has shown signs of steady
recovery and growth.  The State Department of Finance reports net job growth,
particularly in construction and related manufacturing, wholesale and retail
trade, transportation, recreation and services.  This growth has offset the
continuing but slowing job losses in the aerospace industry and restructuring of
the finance and utility sectors.  Unemployment in California is down
substantially in 1994 from its 10% peak in January, 1994, but still remains
higher than the national average rate.  Retail sales are up strongly in 1994
from

                                       18

year-earlier figures.  Delay or slowdown in recovery will adversely affect
California's revenues.

      Orange County.  On December 6, 1994, Orange County, California (the
      -------------                                                      
"County"), together with its pooled investment funds (the "Pooled Funds") filed
for protection under chapter 9 of the federal Bankruptcy Code, after reports
that the Pooled Funds had suffered significant market losses in their
investments causing a liquidity crisis for the Pooled Funds and the County.
More than 180 other public entities, most but not all located in the County,
were also depositors in the Pooled Funds.  As of mid-January, 1995, the County
estimated the Pooled Funds' loss at about $1.8 billion, or 22% of its initial
deposits of around $7.5 billion.  The Pooled Funds have been almost completely
restructured to reduce their exposure to changes in interest rates.  Many of the
entities which kept moneys in the Pooled Funds, including the County, are facing
cash flow difficulties because of the bankruptcy filing and may be required to
reduce programs or capital projects.  The County and some of these entities
have, and others may in the future, defaulted in payment of their obligations.
Moody's and Standard & Poor's have suspended, reduced to below investment grade
levels, or placed on "Credit Watch" various securities of the County and the
entities participating in the Pooled Funds.

      The State of California has no existing obligation with respect to any
outstanding obligations or securities of the County or any of the other
participating entities.  However, the State may be obligated to ensure that
school districts have sufficient funds to operate or to maintain certain county
administered state programs.

Constitutional Limitations on Taxes and Appropriations
- ------------------------------------------------------

Limitations on Taxes.   Certain California Instruments may be obligations of
- --------------------                                                        
issuers which rely in whole or in part, directly or indirectly, on ad valorem
property taxes as a source of revenue.  The taxing power of California local
governments and districts is limited by Article XIIIA of the California
"Proposition 13." Briefly, Article XIIIA limits to 1% of full cash value the
rate of ad valorem property taxes on real property and generally restricts the
reassessment of property to 2% per year, except upon new construction or change
of ownership (subject to a number of exemptions).  Taxing entities may, however,
raise ad valorem taxes above the 1% limit to pay debt service on voter-approved
bonded indebtedness.

      Under Article XIIIA, the basic 1% ad valorem tax levy is applied against
the assessed value of property as of the owner's date of acquisition (or as of
March 1, 1975, if acquired earlier), subject to certain adjustments.  This
system has resulted in widely varying amounts of tax on similarly situated

                                       19
<PAGE>
 
properties.  Several lawsuits have been filed challenging the acquisition-based
assessment system of Proposition 13, and on June 18, 1992 the U.S. Supreme Court
announced a decision upholding Proposition 13.

      Article XIIIA prohibits local governments from raising revenues through ad
valorem property taxes above the 1% limit; it also requires voters of any
governmental unit to give two-thirds approval to levy any "special tax".  Court
decisions, however, allowed non-voter approved levy of "general taxes" which
were not dedicated to a specific use.  In response to these decisions, the
voters of the State in 1986 adopted an initiative statute which imposed
significant new limits on the ability of  local entities to raise or levy
general taxes, except by receiving majority local voter approval.  Significant
elements of this initiative, "Proposition 62", have been overturned in recent
court cases.  An initiative proposed to re-enact the provisions of Proposition
62 as a constitutional amendment was defeated by the voters in November 1990,
but such a proposal may be renewed in the future.

Appropriation Limits.    The State and its local governments are subject to an
- --------------------                                                          
annual "appropriations limit" imposed by Article XIIIB of the California
Constitution, enacted by the voters in 1979 and significantly amended by
Propositions 98 and 111 in 1988 and 1990, respectively.  Article XIIIB prohibits
the State or any covered local government from spending "appropriations subject
to limitation" in excess of the appropriations limit imposed.  "Appropriations
subject to limitation" are authorizations to spend "proceeds of taxes," which
consist of tax revenues and certain other funds, including proceeds from
regulatory licenses, user charges or other fees, to the extent that such
proceeds exceed the cost of providing the product or service, but "proceeds of
taxes" excludes most State subventions to local governments.  No limit is
imposed on appropriations of funds which are not "proceeds of taxes," such as
reasonable user charges or fees, and certain other non-tax funds, including bond
proceeds.

      Among the expenditures not included in the Article XIIIB appropriations
limit are (1) the debt service cost of bonds issued or authorized prior to
January 1, 1979, or subsequently authorized by the voters, (2) appropriations
arising from certain emergencies declared by the Governor, (3) appropriations
for certain capital outlay projects, (4) appropriations by the State of post
1989 increases in gasoline taxes and vehicle weight fees, and (5) appropriations
made in certain cases of emergency.

      The appropriations limit for each year is adjusted annually to reflect
changes in cost of living and population and any transfer of service
responsibilities between governmental units.  The definitions for such
adjustments were liberalized in 1990 to follow more closely growth in the
State's economy.

                                       20
<PAGE>
 
      "Excess" revenues are measured over a two year cycle.  Local governments
must return any excess to taxpayers by rate reductions.  The State must refund
50% paid to schools and  community colleges.  With more liberal annual
adjustment factors since 1988, and depressed revenues since 1990 because of the
recession, few governments, including the State, are currently operating near
their spending limits, but this condition may change over time.  Local
governments may by voter approval exceed their spending limits for up to four
years.

      Because of the complex nature of Articles XIIIA and XIIIB of the
California Constitution, the ambiguities and possible inconsistencies of their
terms, and the impossibility of predicting future appropriations or changes in
population and cost of living, and the probability of continuing legal
challenges, it is not currently possible to determine fully the impact of
Article XIIIA or Article XIIIB on California Instruments.  It is not presently
possible to predict the outcome of any pending litigation with respect to the
ultimate scope, impact or constitutionality of either Article XIIIA or Article
XIIIB, or the impact of any such determinations upon State agencies or local
governments, or upon their ability to pay debt service or their obligations.
Future initiatives or legislative changes in laws or the California Constitution
may also affect the ability of the State or local issuers to repay their
obligations.

      State Debt.  Under the California Constitution, debt service on
      ----------                                                     
outstanding general obligation bonds is the second charge to the General Fund
after support of the public school system and public institutions of higher
education.  Total outstanding general obligation bonds and lease purchase debt
of California increased from $9.4 billion at June 30, 1987 to $23 billion at
June 30, 1994.  In FY1993-94, debt service on general obligation bonds and lease
purchase debt was approximately 5.2% of General Fund revenues.

      Cash Flow Requirements.  To meet its seasonal cash flow needs, California
      ----------------------                                                   
has used internal borrowing resources (temporary loans from the Special Fund for
Economic Uncertainties and its special funds) and issued tax and revenue
anticipation notes.  California's short term borrowing requirements in the
public credit markets have increased substantially in recent years, rising from
$3.0 billion in FY1987-88 to $7.0 billion in 1994-95.  Because of the
accumulated budget deficit over the past several years (described below), the
payment of certain unbudgeted expenditures to schools to maintain constant per-
pupil aid levels, and a reduction of the level of available internal borrowing,
California's cash resources have been significantly depleted.  This has required
California to rely on a series of external borrowings for the past several years
to pay its normal expenses, including repayment of previous cash flow
borrowings.

                                       21
<PAGE>
 
Since June 1992, some of these borrowings have gone past the end of the fiscal
year.  In February, 1994, California borrowed $3.2 billion, maturing by
December, 1994.  In July, 1994, California borrowed a total of $7.0 billion to
meet its cash flow requirements for the 1994-95 fiscal year, and to fund a part
of its deficit into the 1995-96 fiscal year.  A total of $4.0 billion of this
borrowing matures in April, 1996.  California will continue to have to rely on
external borrowing to meet its cash needs for the foreseeable future.  No
assurance can be given that California will be able to continue to meet its
financing requirements in the public credit markets at the times or in the
amounts required.

      Recent Financial Results.   The principal sources of General Fund revenues
      ------------------------                                                  
in 1992-1993 were the California personal income tax (44% of total revenues),
the sales tax (38%), bank and corporation taxes (12%), and the gross premium tax
on insurance (3%).  California maintains a Special Fund for Economic
Uncertainties, derived from General Fund revenues, as a reserve to meet cash
needs of the General Fund.

      General.  Throughout the 1980s, California state spending increased
      -------                                                            
rapidly as California's population and economy also grew rapidly, including
increased spending for many assistance programs to local governments, which were
constrained by Proposition 13 and other laws.  The largest state program is
assistance to local public school districts.  In 1988, an initiative
(Proposition 98) was enacted which (subject to suspension by a two-thirds vote
of the Legislature and the Governor) guarantees local school districts and
community college districts a minimum share of California General Fund revenues
(currently 33%).

      Since the start of 1990-91 Fiscal Year, California has faced adverse
economic, fiscal and budget conditions.  The economic recession seriously
affected California's tax revenues.  It also  caused increased expenditures for
health and welfare programs.  California is also facing a structural imbalance
in its budget with the largest programs supported by the General Fund
(education, health, welfare and corrections) growing at rates higher than the
growth rates for the principal revenue sources of the General Fund.  These
structural concerns will be exacerbated in coming years by the expected need to
substantially increase capital and operating funds for corrections as a result
of a "Three Strikes" law enacted in 1994.  As a result, California entered a
period of budget imbalance, with expenditures exceeding revenues for four of the
five fiscal years ending in 1991-92; revenues and expenditures were about equal
in 1992-93.  By June 30, 1993, California's General Fund had an accumulated
deficit, on a budget basis, of approximately $2.8 billion.

                                       22
<PAGE>
 
      Recent Budgets.  California failed to enact its 1992-93 budget by July 1,
      --------------                                                           
1992.  Although the State of California had no legal authority to pay many of
its vendors, certain obligations (such as debt service, school apportionments,
welfare payments and employee salaries) were payable because of continuing or
special appropriations, or court orders.  However, California's Controller did
not have enough cash to pay as they came due all of these ongoing obligations,
as well as valid obligations incurred in the prior fiscal year.

      Starting on July 1, 1992, the Controller was required to issue "registered
warrants" in lieu of normal warrants backed by cash to pay many State
obligations.  Available cash was used to pay constitutionally mandated and
priority obligations.  Between July 1 and September 3, 1992, the Controller
issued an aggregate of approximately $3.8 billion of registered warrants all of
which were called for redemption by September 4, 1992 following enactment of the
1992-93 Budget Act and issuance by California of short-term notes.

      The 1992-93 Budget Act, when finally adopted, was projected to eliminate
California's accumulated deficit, with additional expenditure cuts and a $1.3
billion transfer of state education funding costs to local governments by
shifting local property taxes to school districts.  However, as the recession
continued longer and deeper than expected, revenues once again were far below
projections, and only reached a level just equal to the amount of expenditures.
Thus, California continued to carry its $2.8 billion budget deficit at June 30,
1993.

      The 1993-94 Budget Act represented a third consecutive year of difficult
budget choices.  As in the prior year, the budget contained no general state tax
increases, and relied principally on expenditure costs, particularly for health
and welfare and higher education, a two-year suspension of the renters' tax
credit, some one-time and accounting adjustments, and -- the largest component -
- - an additional $2.6 billion transfer of property taxes from local government,
particularly counties, to school districts to reduce state education funding
requirements.   A temporary state sales tax scheduled to expire on June 30, 1993
was extended for six months, and dedicated to support local government public
safety costs.

      A major feature of the budget was a two-year plan to eliminate the
accumulated deficit by borrowing into the 1994-95 fiscal year.  With the
recession still continuing longer than expected, the General Fund had $800
million less revenue and $800 million higher expenditures than budgeted.  As a
result revenues only exceed expenditures by about $500 million.  However, this
was the first operating surplus in four years and reduced the accumulated
deficit to $2.0 billion at June 30, 1994 (after taking account of certain other
accounting reserves).

                                       23

      Current Budget.  The 1994-95 Budget Act was passed on July 8, 1994, and
      --------------                                                         
provides for an estimated $41.9 billion of General Fund revenues, and $40.9
billion of expenditures.  The budget assumed receipt of about $750 million of
new federal assistance for the costs of incarceration, education, health and
welfare related to undocumented immigrants.  Other major components of the
budget include further reductions in health and welfare costs and miscellaneous
government costs, some additional transfers of funds from local government, and
a plan to defer retirement of $1 billion of the accumulated budget deficit to
the 1995-96 fiscal year.  The federal government has apparently budgeted only
$33 million of the expected immigration aid.  However, this shortfall is
expected to be almost fully offset by higher than projected revenues, and lower
than projected caseload growth, as the economy improves.

      As noted above under "Cash Flow Requirements," California issued $7.0
billion of short-term debt in July, 1994 to meet its cash flow needs and to
finance the deferral of part of the accumulated budget deficit to the 1995-96
fiscal year.  In order to assure repayment of the $4 billion, 22-month part of
this borrowing, California enacted legislation (the "Trigger Law") which can
lead to automatic, across-the-board cuts in General Fund expenditures in either
the 1994-95 or 1995-96 fiscal years if cash flow projections made at certain
times during those years show deterioration from the projections made in July
1994 when the borrowings were made.  On November 15, 1994, California's
Controller as part of the Trigger Law reported that the cash position of the
General Fund on June 30, 1995 would be about $580 million better than earlier
projected, so no automatic budget adjustments were required in 1994-95.  The
Controller's report showed that loss of federal funds was offset by higher
revenues, lower expenditures, and certain other increases in cash resources.

      Proposed 1995-96 Budget.  On January 10, 1995, the Governor presented his
      -----------------------                                                  
proposed FY 1995-96 Budget.  This budget projects total General Fund revenues
and transfers of $42.5 billion, and expenditures of $41.7 billion, to complete
the elimination of the accumulated deficits from earlier years.  However, this
proposal leaves no cushion, as the projected budget reserve at June 30,  1996
would be only about $92 million.  While proposing increases in funding for
schools, universities and corrections, the Governor proposes further cuts in
welfare programs, and a continuation of the "realignment" of functions with
counties which would save California about $240 million.  The Governor also
expects about $800 million in new federal aid for California's costs of
incarcerating and educating illegal immigrants.  The Budget proposal also does
not account for possible additional costs if California loses its appeals on
lawsuits which are currently pending concerning such matters as school funding
and pension payments, but these appeals could take

                                       24
<PAGE>
 
several years to resolve.  Part of the Governor's proposal also is a 15% cut in
personal income and corporate taxes, to be phased in over three years, starting
with calendar year 1996 (which would have only a small impact on 1995-96
income).

      California's difficult financial condition for the current and upcoming
years will result in continued pressure upon almost all local governments,
particularly school districts and counties which depend on state aid.  Despite
efforts in recent years to increase taxes and reduce governmental expenditures,
there can be no assurance that California will not face budget gaps in the
future.

      Bond Ratings.  State general obligation bond ratings were reduced in July,
      ------------                                                              
1994 to "A1" by Moody's Investors Services, Inc. ("Moody's") and "A" by Standard
& Poor's Ratings Group ("S&P").  Both of these ratings were reduced from "AAA"
levels which California held until late 1991.  There can be no assurance that
such ratings will be maintained in the future.  It should be noted that the
creditworthiness of obligations issued by local California issuers may be
unrelated to the creditworthiness of obligations issued by the State of
California, and that there is no obligation on the part of California to make
payment on such obligations in the event of default.

      Legal Proceedings.  California is involved in certain legal proceedings
      ------------------                                                     
(described in California's recent financial statements) that, if decided against
California, may require California to make significant future expenditures or
may substantially impair revenues.  Trial courts have recently entered tentative
decisions or injunctions which would overturn several parts of the state's
recent budget compromises.  The matters covered by these lawsuits include a
deferral of payments by California to the Public Employees Retirement System,
reductions in welfare payments and the use of certain cigarette tax funds for
health costs.  All of these cases are subject to further proceedings and
appeals, and if California eventually loses, the final remedies may not have to
be implemented in one year.

      Obligations of Other Issuers
      ----------------------------

      Other Issuers of California Instruments.  There are a number of state
      ---------------------------------------                              
agencies, instrumentalities and political subdivisions of the State of
California that issue municipal obligations, some of which may be conduit
revenue obligations payable from payments from private borrowers.  These
entities are subject to various economic risks and uncertainties, and the credit
quality of the securities issued by them may vary considerably from the credit
quality of obligations backed by the full faith and credit of the State of
California.

                                       25
<PAGE>
 
      State Assistance.  Property tax revenues received by local governments
      ----------------                                                      
declined more than 50% following passage of Proposition 13.  Subsequently, the
California Legislature enacted measures to provide for the redistribution of
California's General Fund surplus to local agencies, the reallocation of certain
state revenues to local agencies and the assumption of certain governmental
functions by the State of California to assist municipal issuers to raise
revenues.  Through 1990-91, local assistance (including public schools)
accounted for around 75% of General Fund spending.  To reduce California General
Fund support for school districts, the 1992-93 and 1993-94 Budget Acts caused
local governments to transfer a total of $3.9 billion of property tax revenues
to school districts, representing loss of all the post-Proposition 13 "bailout"
aid.  The largest share of these transfers came from counties, and the balance
from cities, special districts and redevelopment agencies.  In order to make up
part of this shortfall, the Legislature proposed, and voters approved in 1993,
dedicating 0.5% of the sales tax to counties and cities for public safety
purposes.  In addition, the Legislature has changed laws to relieve local
governments of certain mandates, allowing them to reduce costs.

      To the extent that California should be constrained by its Article XIIIB
appropriations limit, or its obligation to conform to Proposition 98, or other
fiscal considerations, the absolute level, or the rate of growth, of state
assistance to local governments may continue to be reduced.  Any such reductions
in state aid could compound the serious fiscal constraints already experienced
by many local governments, particularly counties.  At least one rural county
(Butte) publicly announced that it might enter bankruptcy proceedings in August
1990, although such plans were put off after the Governor approved legislation
to provide additional funds for the county.  Other counties have also indicated
that their budgetary condition is extremely grave.  The Richmond Unified School
District (Contra Costa County) entered bankruptcy proceedings in May 1991, but
the proceedings have been dismissed.

      Assessment Bonds.  California Instruments which are assessment bonds may
      ----------------                                                        
be adversely affected by a general decline in real estate values or a slowdown
in real estate sales activity.  In many cases, such bonds are secured by land
which is undeveloped  at the time of issuance but anticipated to be developed
within a few years after issuance.  In the event of such reduction or slowdown,
such development may not occur or may be delayed, thereby increasing the risk of
a default on the bonds.  Because the special assessments or taxes securing these
bonds are not the personal liability of the owners of the property assessed, the
lien on the property is the only security for the bonds.  Moreover, in most
cases the issuer of these bonds is not required to make payments on the bonds in
the event of

                                       26
<PAGE>
 
delinquency in the payment of assessments or taxes, except from amounts, if any,
in a reserve fund established for the bonds.

      California Long-Term Lease Obligations.  Certain California long-term
      --------------------------------------                               
lease obligations, though typically payable from the general fund of the
municipality, are subject to "abatement" in the event the facility being leased
is unavailable for beneficial use and occupancy by the municipality during the
term of the lease.  Abatement is not a default, and there may be no remedies
available to the holders of the certificates evidencing the lease obligation in
the event abatement occurs.  The most common cases of abatement are failure to
complete construction of the facility before the end of the period during which
lease payments have been capitalized and uninsured casualty losses to the
facility (e.g. due to earthquake).  In the event abatement occurs with respect
to a lease obligation, lease payments may be interrupted (if all available
insurance proceeds and reserves are exhausted) and the certificates may not be
paid when due.

      Several years ago the Richmond Unified School District (the "District")
entered into a lease transaction in which certain existing properties of the
District were sold and leased back in order to obtain funds to cover operating
deficits.  Following a fiscal crisis in which the District's finances were taken
over by a state receiver (including a brief period under bankruptcy court
protection), the District failed to make rental payments on this lease,
resulting in a lawsuit by the Trustee for the Certificate of Participation
holders, in which the State of California was a named defendant (on the grounds
that it controlled the District's finances).  One of the defenses raised in
answer to this lawsuit was the invalidity of the District's lease.  The trial
court upheld the validity of the lease, and the case was subsequently settled.
Any ultimate judgment in any future case against the position taken by the
Trustee may have adverse implications for lease transactions of a similar nature
by other California entities.

      Other Considerations
      --------------------

      The repayment of industrial development securities secured by real
property may be affected by California laws limiting foreclosure rights of
creditors.  Securities backed by health care and hospital revenues may be
affected by changes in state regulations governing cost reimbursements to health
care providers under Medi-Cal (the State's Medicaid program), including risks
related to the policy of awarding exclusive contracts to certain hospitals.

      Limitations on ad valorem property taxes may particularly affect "tax
allocation" bonds issued by California redevelopment agencies.  Such bonds are
secured solely by the increase in

                                       27
<PAGE>
 
assessed valuation of a redevelopment project area after the start of
redevelopment activity.  In the event that assessed values in the redevelopment
project decline (e.g. because of major natural disaster such as an earthquake),
the tax increment revenue may be insufficient to make principal and interest
payments on these bonds.  Both Moody's and S&P suspended ratings on California
tax allocation bonds after the enactment of Articles XIIIA and XIIIB, and only
resumed such ratings on a selective basis.
 
      Proposition 87, approved by California voters in 1988, requires that all
revenues produced by a tax rate increase go directly to the taxing entity which
increased such tax rate to repay that entity's general obligation indebtedness.
As a result, redevelopment agencies (which typically are the issuers of tax
allocation securities) no longer receive an increase in tax increment when taxes
on property in the project area are increased to repay voter-approved bonded
indebtedness.

      The effect of these various constitutional and statutory changes upon the
ability of California municipal securities issuers to pay interest and principal
on their obligations remains unclear.  Furthermore, other measures affecting the
taxing or spending authority of California or its political subdivisions may be
approved or enacted in the future.  Legislation has been or may be introduced
which would modify existing taxes or other revenue raising measures or which
either would further limit or, alternatively, would increase the abilities of
state and local governments to impose new taxes or increase existing taxes.  It
is not presently possible to predict the extent to which any such legislation
will be enacted.  Nor is it presently possible to determine the impact of any
such legislation on California Instruments in which the California Portfolio may
invest, future allocations of state revenues to local governments or the
abilities of state or local governments to pay the interest on, or repay the
principal of, such California Instruments.

      Substantially all of California is within an active geologic region
subject to major seismic activity.  Northern California in 1989 and Southern
California in 1994 experienced major earthquakes causing billions of dollars in
damages.  The federal government provided more than $13 billion in aid for both
earthquakes, and neither event is expected to have any long-term negative
economic impact.  Any security in the California Portfolio could be affected by
an interruption of revenues because of damaged facilities, or, consequently,
income tax deductions for casualty losses or property tax assessment reductions.
Compensatory financial assistance could be constrained by the inability of (i)
an issuer to have obtained earthquake insurance coverage at  reasonable rates;
(ii) an insurer to perform on its contracts of insurance in the event of

                                       28

widespread losses; or (iii) the federal or state government to appropriate
sufficient funds within their respective budget limitations.

INVESTING IN NEW YORK
- ---------------------

      Some of the significant financial considerations relating to the Tax-
Exempt New York Portfolio's investment in New York municipal securities are
summarized below.  This summary information is not intended to be a complete
description and is principally derived from official statements relating to
issues of New York municipal securities that were available prior to the date of
this Additional Statement.  The accuracy and completeness of the information
contained in those official statements have not been independently verified.

      State Economy.  New York is the third most populous state in the nation
      -------------                                                          
and has a relatively high level of personal wealth.  The State's economy is
diverse with a comparatively large share of the nation's finance, insurance,
transportation, communications and services employment, and a very small share
of the nation's farming and mining activity.  The State has a declining
proportion of its workforce engaged in manufacturing, and an increasing
proportion engaged in service industries.  New York City (the "City"), which is
the most populous city in the State and nation and is the center of the nation's
largest metropolitan area, accounts for a large portion of the State's
population and personal income.

      The State has historically been one of the wealthiest states in the
nation.  For decades, however, the State has grown more slowly than the nation
as a whole, gradually eroding its relative economic position.  The recession has
been more severe in the State, owing to a significant retrenchment in the
financial services industry, cutbacks in defense spending, and an overbuilt real
estate market.  There can be no assurance that the State economy will not
experience worse-than-predicted results in the 1994-95 fiscal year, with
corresponding material and adverse effects on the State's projections of
receipts and disbursements.

      The unemployment rate in the State dipped below the national rate in the
second half of 1981 and remained lower  until 1991.  It stood at 7.7% in 1993.
The total employment growth rate in the State has been below the national
average since 1984.  State per capita personal income remains above the national
average.  State per capita income for 1993 was $24,623, which is 18.3% above the
1993 national average of $20,817. During the past ten years, total personal
income in the State rose slightly faster than the national average only in 1986
through 1989.

                                       29

      State Budget.  The State Constitution requires the Governor to submit to
      ------------                                                            
the Legislature a balanced Executive Budget which contains a complete plan of
expenditures for the ensuing fiscal year and all moneys and revenues estimated
to be available therefor, accompanied by bills containing all proposed
appropriations or reappropriations and any new or modified revenue measures to
be enacted in connection with the Executive Budget.  The entire plan constitutes
the proposed State financial plan for that fiscal year.  The Governor is
required to submit to the Legislature quarterly budget updates which include a
revised cash-basis state financial plan, and an explanation of any changes from
the previous state financial plan.

      The State's budget for the 1994-95 fiscal year was enacted by the
Legislature on June 7, 1994, more than two months after the start of the fiscal
year.  Prior to adoption of the budget, the Legislature enacted appropriations
for disbursements considered to be necessary for State operations and other
purposes, including all necessary appropriations for debt service.  The State
financial plan for the 1994-95 fiscal year was formulated on June 16, 1994 and
is based upon the State's budget as enacted by the Legislature and signed into
law by the Governor (the "1994-95 State Financial Plan").  This delay in the
enactment of the State's 1994-95 fiscal year budget may reduce the effectiveness
of several of the actions proposed.

      The State issued its second quarterly update to the cash basis 1994-95
State Financial Plan on October 28, 1994.  The update projects a year-end
surplus of $14 million in the General Fund, with estimated receipts reduced by
$267 million and estimated disbursements reduced by $281 million, compared to
the 1994-95 State Financial Plan as initially formulated.

      The 1994-95 State Financial Plan is based on a number of assumptions and
projections.  Because it is not possible to predict accurately the occurrence of
all factors that may affect the 1994-95 State Financial Plan, actual results may
differ and have differed materially in recent years, from projections made at
the outset of a fiscal year.  There can be no assurance that the State will not
face substantial potential budget gaps in future years resulting from a
significant disparity between tax revenues projected from a lower recurring
receipts base and the spending required to maintain State programs at current
levels.  To address any potential budgetary imbalance, the State may need to
take significant actions to align recurring receipts and disbursements in future
fiscal years.

      Recent Financial Results.  The General Fund is the general operating fund
      ------------------------                                                 
of the State and is used to account for all financial transactions, except those
required to be accounted for in another fund.  It is the State's largest fund
and receives almost all State taxes and other resources not dedicated to

                                       30
<PAGE>
 
particular purposes.   In the State's 1994-95 fiscal year, the General Fund is
expected to account for approximately 52% of total governmental-fund receipts
and 51% of total governmental-fund disbursements.

      The General Fund is projected to be balanced on a cash basis for the 1994-
95 fiscal year.  Total receipts are projected to be $34.321 billion, an increase
of $2.092 billion over total receipts in the prior fiscal year.  Total General
Fund disbursements are projected to be $34.248 billion, an increase of $2.351
billion over the total amount disbursed and transferred in the prior fiscal
year.

      The State's financial position on a GAAP (generally accepted accounting
principles) basis as of March 31, 1993 included an 1991-92 accumulated deficit
in its combined governmental funds of $681 million.  Liabilities totalled
$12.864 billion and assets of $12.183 billion were available to liquidate these
liabilities.

      The State's financial operations have improved during recent fiscal years.
During the period 1989-90 through 1991-92, the State incurred General Fund
operating deficits that were closed with receipts from the issuance of tax and
revenue anticipation notes.  The national recession and then the lingering
economic slowdown in the New York and regional economy, resulted in repeated
shortfalls in receipts and three budget deficits.  For its 1992-93 and 1993-94
fiscal years, however, the State recorded balanced budgets on a cash basis, with
substantial fund balances in each year.

    
      Debt Limits and Outstanding Debt.  There are a number of methods by which
      --------------------------------                                         
the State of New York may incur debt.  Under the State Constitution, the State
may not, with limited exceptions for emergencies, undertake long-term general
obligation borrowing (i.e., borrowing for more than one year) unless the
borrowing is authorized in a specific amount for a single work or purpose by the
Legislature and approved by the voters.  There is no limitation on the amount of
long-term general obligation debt that may be so authorized and subsequently
incurred by the State.  The total amount of long-term State general obligation
debt authorized but not issued as of December 31, 1993 was approximately $2.273
billion.     

      The State may undertake short-term borrowings without voter approval (i)
in anticipation of the receipt of taxes and revenues, by issuing tax and revenue
anticipation notes, and (ii) in anticipation of the receipt of proceeds from the
sale of duly authorized but unissued general obligation bonds, by issuing bond
anticipation notes.  The State may also, pursuant to specific constitutional
authorization, directly guarantee certain obligations of the State of New York's
authorities and public

                                       31
<PAGE>
 
benefit corporations ("Authorities").  Payments of debt service on New York
State general obligation and New York State-guaranteed bonds and notes are
legally enforceable obligations of the State of New York.

      The State employs additional long-term financing mechanisms, lease-
purchase and contractual-obligation financings, which involve obligations of
public authorities or municipalities that are State-supported but are not
general obligations of the State.  Under these financing arrangements, certain
public authorities and municipalities have issued obligations to finance the
construction and rehabilitation of facilities or the acquisition of equipment,
and expect to meet their debt service requirements through the receipt of rental
or other contractual payments made by the State.  Although these financing
arrangements involve a contractual agreement by the State to make payments to a
public authority, municipality or other entity, the State's obligation to make
such payments is generally expressly made subject to appropriation by the
Legislature and the actual availability of money to the State for making the
payments.  The State has also entered into a contractual-obligation financing
arrangement with the Local Government Assistance Corporation ("LGAC") in an
effort to restructure the way the State makes certain local aid payments.

      In 1990, as part of a State fiscal reform program, legislation was enacted
creating LGAC, a public benefit corporation empowered to issue long-term
obligations to fund certain payments to local governments traditionally funded
through New York State's annual seasonal borrowing.  The legislation empowered
LGAC to issue its bonds and notes in an amount not in excess of $4.7 billion
(exclusive of certain refunding bonds) plus certain other amounts.  Over a
period of years, the issuance of these long-term obligations, which are to be
amortized over no more than 30 years, was expected to eliminate the need for
continued short-term seasonal borrowing.   The legislation also dedicated
revenues equal to one-quarter of the four cent State sales and use tax to pay
debt service on these bonds.  The legislation also imposed a cap on the annual
seasonal borrowing of the State at $4.7 billion, less net proceeds of bonds
issued by LGAC and bonds issued to provide for capitalized interest, except in
cases where the Governor and the legislative leaders have certified the need for
additional borrowing and provided a schedule for reducing it to the cap.  If
borrowing above the cap is thus permitted in any fiscal year, it is required by
law to be reduced to the cap by the fourth fiscal year after the limit was first
exceeded.  As of December 1994, LGAC had issued bonds to provide net proceeds of
$3.856 billion and has been authorized to issue its bonds to provide net
proceeds of up to an additional $315 million during the State's 1994-95 fiscal
year.  The impact of this borrowing, together with the availability of certain
cash reserves, is that, for the first

                                       32
<PAGE>
 
time in nearly 35 years, the 1994-95 State Financial Plan includes no short-term
seasonal borrowing.

      In April 1993, legislation was enacted proposing significant
constitutional changes to the long-term financing practices of the State and the
Authorities.

      The Legislature passed a proposed constitutional amendment that would
permit the State, within a formula-based cap, to issue revenue bonds, which
would be debt of the State secured solely by a pledge of certain State tax
receipts (including those allocated to State funds dedicated for transportation
purposes), and not by the full faith and credit of the State.  In addition, the
proposed amendment would require that State debt be incurred only for capital
projects included in a multi-year capital financing plan and would prohibit,
after its effective date, lease-purchase and contractual-obligation financing
mechanisms for State facilities.  Public hearings were held on the proposed
constitutional amendment during 1993.  Following these hearings, in February
1994, the Governor and the State Comptroller recommended a revised
constitutional amendment which would further tighten the ban on lease-purchase
and contractual-obligation financing, incorporate existing lease-purchase and
contractual-obligation debt under the proposed revenue bond cap while
simultaneously reducing the size of the cap.  After considering these
recommendations, the Legislature passed a revised constitutional amendment which
tightens the ban, and provides for a phase-in to a lower cap.  Before the
approved constitutional amendment or any revised amendment enacted in 1994 can
be presented to the voters for their consideration, it must be passed by a
separately elected legislature.  The amendment must therefore be passed by the
newly elected Legislature in 1995 prior to presentation to the voters at the
earliest in November 1995.  The amendment could not become effective before
January 1, 1996.

      On January 13, 1992, S&P reduced its ratings on the State's general
obligation bonds from A to A- and, in addition, reduced its ratings on the
State's moral obligation, lease purchase, guaranteed and contractual obligation
debt.  S&P also continued its negative rating outlook assessment on State
general obligation debt.  On April 26, 1993, S&P revised the rating outlook
assessment to stable.  On February 14, 1994, S&P raised its outlook to positive
and, on February 28, 1994, confirmed its A- rating.  On January 6, 1992, Moody's
reduced its ratings on outstanding limited-liability State lease purchase and
contractual obligations from A to Baa1.  On February 28, 1994, Moody's
reconfirmed its A rating on the State's general obligation long-term
indebtedness.

      The State anticipates that its capital programs will be financed, in part,
by State and public authorities borrowings in

                                       33
<PAGE>
 
1994-95.  The State expects to issue $374 million in general obligation bonds
(including $140 million for purposes of redeeming outstanding bond anticipation
notes) and $140 million in general obligation commercial paper.  The Legislature
has also authorized the issuance of up to $69 million in certificates of
participation during the State's 1994-95 fiscal year for equipment purchases.
The projection of the State regarding its borrowings for the 1994-95 fiscal year
may change if circumstances require.

      Principal and interest payments on general obligation bonds and interest
payments on bond anticipation notes and on tax and revenue anticipation notes
were $782.5 million for the 1993-94 fiscal year, and are estimated to be $786.3
million for the 1994-95 fiscal year.  These figures do not include interest
payable on State General Obligation Refunding Bonds issued in July 1992
("Refunding Bonds") to the extent that such interest was paid from an escrow
fund established with the proceeds of such Refunding Bonds.  Principal and
interest payments on fixed rate and variable rate bonds issued by LGAC were
$239.4 million for the 1993-94 fiscal year, and are estimated to be $289.9
million for 1994-95.  State lease-purchase rental and contractual obligation
payments for 1993-94, including State installment payments relating to
certificates of participation, were $1.258 billion and are estimated to be
$1.495 billion in 1994-95.

      New York State has never defaulted on any of its general obligation
indebtedness or its obligations under lease-purchase or contractual-obligation
financing arrangements  and has never been called upon to make any direct
payments pursuant to its guarantees.

      Litigation.  Certain litigation pending against New York State or its
      ----------                                                           
officers or employees could have a substantial or long-term adverse effect on
New York State finances.  Among the more significant of these cases are those
that involve (1) the validity of agreements and treaties by which various Indian
tribes transferred title to New York State of certain land in central and
upstate New York; (2) certain aspects of New York State's Medicaid policies,
including its rates, regulations and procedures; (3) contamination in the Love
Canal area of Niagara Falls; (4) action against New York State and New York City
officials alleging inadequate shelter allowances to maintain proper housing; (5)
challenges to the practice of reimbursing certain Office of Mental Health
patient care expenses from the client's Social Security benefits; (6) alleged
responsibility of New York State officials to assist in remedying racial
segregation in the City of Yonkers; (7) action in which the State is a third
party defendant, for injunctive or other appropriate relief, concerning
liability for the maintenance of stone groins constructed along certain areas of
Long Island's shoreline; (8) challenges by commercial insurers, employee welfare

plans, and health maintenance organizations to Section 2807-c of the Public
Health Law, which imposes 13%, 11% and 9% surcharges on inpatient hospital bills
and a bad debt and charity care allowance on all hospital bills and hospital
bills paid by such entities; (9) challenge by a long distance carrier to the
constitutionality of Tax Law (S)186-a(2-a) which restricted certain deduction of
local access service fees and (10) challenges to certain aspects of petroleum
business taxes.

      A number of cases have also been instituted against the State challenging
the constitutionality of various public authority financing programs.

      In a proceeding commenced on August 6, 1991 (Schulz, et al. v. State of
                                                   --------------------------
New York, et al., Supreme Court, Albany County), petitioners challenged the
- ----------------                                                           
constitutionality of two bonding programs of the New York State Thruway
Authority authorized by Chapters 166 and 410 of the Laws of 1991.  In addition,
petitioners challenge the fiscal year 1991-92 judiciary budget as having been
enacted in violation of Sections 1 and 2 of Article VII of the State
Constitution.  The defendants' motion to dismiss the action on procedural
grounds was denied by order of the Supreme Court dated January 2, 1992.  By
order dated November 5, 1992, the Appellate Division, Third Department, reversed
the order of the Supreme Court and granted defendants' motion to dismiss on
grounds of standing and mootness.  By order dated September 16, 1993, on motion
to reconsider, the Appellate Division, Third Department, ruled that plaintiffs
have standing to challenge the bonding program authorized by Chapter 166 of the
laws of 1991.  The proceeding is presently pending in Supreme Court, Albany
County.

      In Schulz, et al. v. State of New York, et al., commenced May 24, 1993,
         -------------------------------------------                         
Supreme Court, Albany County, petitioners challenge, among other things, the
constitutionality of, and seek to enjoin, certain highway, bridge and mass
transportation bonding programs of the New York State Thruway Authority and the
Metropolitan Transportation Authority authorized by Chapter 56 of the Laws of
1993.  Petitioners contend that the application of State tax receipts held in
dedicated transportation funds to pay debt service on bonds of the Thruway
Authority and of the Metropolitan Transportation Authority violates Sections 8
and 11 of Article VII and Section 5 of Article X of the State Constitution and
due process provisions of the State and Federal Constitutions.  By order dated
July 27, 1993, the Supreme Court granted defendants' motions for summary
judgment, dismissed the complaint, and vacated the temporary restraining order
previously issued.  By decision dated October 21, 1993, the Appellate Division,
Third Department, affirmed the judgment of the Supreme Court.  On June 30, 1994,
the Court of Appeals unanimously affirmed the rulings of the trial court and the
Appellate Division in favor of the State.

      Several actions challenging the constitutionality of legislation enacted
during the 1990 legislative session which changed actuarial funding methods for
determining state and local contributions to state employee retirement systems
have been decided against the State.  As a result, the State's Comptroller has
developed a plan to restore the State's retirement systems to prior funding
levels.  Such funding is expected to exceed prior levels by $30 million in
fiscal 1994-95, $63 million in fiscal 1995-96, $116 million in fiscal 1996-97,
$193 million in fiscal 1997-98, peaking at $241 million in fiscal 1998-99.
Beginning in fiscal 2001-02, State contributions required under the
Comptroller's plan are projected to be less than that required under the prior
funding method.  As a result of the United States Supreme Court decision in the
case of State of Delaware v. State of New York, on January 21, 1994, the State
        -----------------    -----------------                                
entered into a settlement agreement with Delaware.  The State made an immediate
$35 million payment to Delaware and agreed to make annual payments of $33
million in each of the next five fiscal years.  In return, Delaware has agreed
to withdraw its claims and its request for summary judgment.  The State and
Massachusetts have also executed a settlement agreement which provides for
aggregate payments by New York State of $23 million, payable over five
consecutive years.  Litigation continues with respect to other parties and the
State may be required to make additional payments during the State's 1994-95
fiscal year.

      The legal proceedings noted above involve State finances, State programs
and miscellaneous tort, real property and contract claims in which the State is
a defendant and the monetary damages sought are substantial.  These proceedings
could affect adversely the financial condition of the State in the 1994-95
fiscal year or thereafter.  Adverse developments in these proceedings or the
initiation of new proceedings could affect the ability of the State to maintain
a balanced 1994-95 State Financial Plan.  An adverse decision in any of these
proceedings could exceed the amount of the 1994-95 State Financial Plan reserve
for the payment of judgments and, therefore, could affect the ability of the
State to maintain a balanced 1994-95 State Financial Plan.  In its audited
financial statements for the fiscal year ended March 31, 1994, the State
reported its estimated liability for awarded and anticipated unfavorable
judgments to be $675 million.

      Although other litigation is pending against New York State, except as
described above, no current litigation involves New York State's authority, as a
matter of law, to contract indebtedness, issue its obligations, or pay such
indebtedness when it matures, or affects New York State's power or ability, as a
matter of law, to impose or collect significant amounts of taxes and revenues.

      Authorities.  The fiscal stability of New York State is related, in part,
      -----------                                                              
to the fiscal stability of its Authorities,

                                       36
<PAGE>
 
which generally have responsibility for financing, constructing and operating
revenue-producing public benefit facilities.  Authorities are not subject to the
constitutional restrictions on the incurrence of debt which apply to the State
itself, and may issue bonds and notes within the amounts of, and as otherwise
restricted by, their legislative authorization.  The State's access to the
public credit markets could be impaired, and the market price of its outstanding
debt may be materially and adversely affected, if any of the Authorities were to
default on their respective obligations, particularly with respect to debt that
is State-supported or State-related.  As of September 30, 1993, date of the
latest data available, there were 18 Authorities that had outstanding debt of
$100 million or more.  The aggregate outstanding debt, including refunding
bonds, of these 18 Authorities was $63.5 billion.  As of March 31, 1994,
aggregate public authority debt outstanding as State-supported debt was $21.1
billion and as State-related debt was $29.4 billion.

      Authorities are generally supported by revenues generated by the projects
financed or operated, such as fares, user fees on bridges, highway tolls and
rentals for dormitory rooms and housing.  In recent years, however, New York
State has provided financial assistance through appropriations, in some cases of
a recurring nature, to certain of the 18 Authorities for operating and other
expenses and, in fulfillment of its commitments on moral obligation indebtedness
or otherwise, for debt service.  This operating assistance is expected to
continue to be required in future years.  In addition, certain statutory
arrangements provide for State local assistance payments otherwise payable to
localities to be made under certain circumstances to certain Authorities.  The
State has no obligation to provide additional assistance to localities whose
local assistance payments have been paid to Authorities under these
arrangements.  However, in the event that such local assistance payments are so
diverted, the affected localities could seek additional State funds.

      New York City and Other Localities.  The fiscal health of the State of New
      ----------------------------------                                        
York may also be impacted by the fiscal health of its localities, particularly
the City of New York, which has required and continues to require significant
financial assistance from New York State.  The City's independently audited
operating results for each of its 1981 through 1993 fiscal years, which end on
June 30, show a General Fund surplus reported in accordance with GAAP.  In
addition, the City's financial statements for the 1993 fiscal year received an
unqualified opinion from the City's independent auditors, the eleventh
consecutive year the City has received such an opinion.

      In 1975, New York City suffered a fiscal crisis that impaired the
borrowing ability of both the City and New York State.  In that year the City
lost access to public credit

                                       37
<PAGE>
 
markets.  The City was not able to sell short-term notes to the public again
until 1979.

      In 1975, S&P suspended its A rating of City bonds.  This suspension
remained in effect until March 1981, at which time the City received an
investment grade rating of BBB from S&P.  On July 2, 1985, S&P revised its
rating of City bonds upward to BBB+ and on November 19, 1987, to A-.  On July 2,
1993, S&P reconfirmed its A- rating of City bonds, continued its negative rating
outlook assessment and stated that maintenance of such rating depended upon the
City's making further progress towards reducing budget gaps in the outlying
years.  Moody's ratings of City bonds were revised in November 1981 from B (in
effect since 1977) to Ba1, in November 1983 to Baa, in December 1985 to Baa1, in
May 1988 to A and again in February 1991 to Baa1.  On January 17, 1995, S&P's
placed the City's general obligation bonds on its CreditWatch list which may
portend a rating downgrade from the agency in the upcoming months.

      New York City is heavily dependent on New York State and federal
assistance to cover insufficiencies in its revenues.  There can be no assurance
that in the future federal and State assistance will enable the City to make up
its budget deficits.  To help alleviate the City's financial difficulties, the
Legislature created the Municipal Assistance Corporation ("MAC") in 1975.  MAC
is authorized to issue bonds and notes payable from certain stock transfer tax
revenues, from the City's portion of the State sales tax derived in the City and
from State per capita aid otherwise payable by the State to the City.  Failure
by the State to continue the imposition of such taxes, the reduction of the rate
of such taxes to rates less than those in effect on July 2, 1975, failure by the
State to pay such aid revenues and the reduction of such aid revenues below a
specified level are included among the events of default in the resolutions
authorizing MAC's long-term debt.  The occurrence of an event of default may
result in the acceleration of the maturity of all or a portion of MAC's debt.
As of December 31, 1993, MAC had outstanding an  aggregate of approximately
$5.204 billion of its bonds.  MAC bonds and notes constitute general obligations
of MAC and do not constitute an enforceable obligation or debt of either the
State or the City.  Under its enabling legislation, MAC's authority to issue
bonds and notes (other than refunding bonds and notes) expired on December 31,
1984.  Legislation has been passed by the legislature which would, under certain
conditions, permit MAC to issue up to $1.465 billion of additional bonds, which
are not subject to a moral obligation provision.

      Since 1975, the City's financial condition has been subject to oversight
and review by the New York State Financial Control Board (the "Control Board")
and since 1978 the City's financial statements have been audited by independent
accounting firms.  To be eligible for guarantees and assistance, the City is

                                       38
<PAGE>
 
required during a "control period" to submit annually for Control Board
approval, and when a control period is not in effect for Control Board review, a
financial plan for the next four fiscal years covering the City and certain
agencies showing balanced budgets determined in accordance with GAAP.  New York
State also established the Office of the State Deputy Comptroller for New York
City ("OSDC") to assist the Control Board in exercising its powers and
responsibilities.  On June 30, 1986, the City satisfied the statutory
requirements for termination of the control period.  This means that the Control
Board's powers of approval are suspended, but the Board continues to have
oversight responsibilities.

      The staffs of OSDC and the Control Board issued periodic reports on the
City's financial plans, as modified, analyzing forecasts of revenues and
expenditures, cash flow, and debt service requirements, as well as compliance
with the financial plan, as modified, by the City and its Covered Organizations
(i.e., those which receive or may receive monies from the City directly,
indirectly or contingently).  OSDC staff reports issued during the mid-1980's
noted that the City's budgets benefited from a rapid rise in the City's economy,
which boosted the City's collection of property, business and income taxes.
These resources were used to increase the City's workforce and the scope of
discretionary and mandated City services.  Subsequent OSDC staff reports
examined the 1987 stock market crash and the 1989-92 recession, which affected
the City's region more severely than the nation, and attributed an erosion of
City revenues and increasing strain on City expenditures to that recession.
According to a recent OSDC staff report, the City's economy is now slowly
recovering, but the scope of that recovery is uncertain and unlikely, in the
forseeable future, to match the expansion of the mid-1980's.  Also, staff
reports of OSDC and the Control Board have indicated that the City's recent
balanced budgets have been accomplished, in part, through the use of non-
recurring resources, tax increases and additional State assistance; that the
City has not yet brought its long-term expenditures in line with recurring
revenues; and that the City is therefore likely to continue to face future
projected budget gaps requiring the City to increase revenues and/or reduce
expenditures.  According to the most recent staff reports of OSDC and the
Control Board, during the four-year period covered by the current financial
plan, the City is relying on obtaining substantial resources from initiatives
needing approval and cooperation of its municipal labor unions, Covered
Organizations and City Council, as well as the state and federal governments,
among others.

      Although the City has balanced its budget since 1981, estimates of the
City's revenues and expenditures, which are based on numerous assumptions, are
subject to various uncertainties. If expected federal or State aid is not forth-

                                       39
<PAGE>
 
coming, if unforeseen developments in the economy significantly reduce revenues
derived from economically sensitive taxes or necessitate increased expenditures
for public assistance, if the City should negotiate wage increases for its
employees greater than the amounts provided for in the City's financial plan or
if other uncertainties materialize that reduce expected revenues or increase
projected expenditures, then, to avoid operating deficits, the City may be
required to implement additional actions, including increases in taxes and
reductions in essential City services.  The City might also seek additional
assistance from New York State.

      The City requires certain amounts of financing for seasonal and capital
spending purposes.  The City has issued $1.75 billion of notes for seasonal
financing purposes during fiscal year 1994.  The City's capital financing
program projects long-term financing requirements of approximately $17 billion
for the City's fiscal years 1995 through 1998.  The major capital requirements
include expenditures for the City's water supply and sewage disposal systems,
roads, bridges, mass transit, schools, hospitals and housing.  In addition to
financing for new purposes, the City and the New York City Municipal Water
Finance Authority have issued refunding bonds totalling $1.8 billion in fiscal
year 1994.

      Certain localities, in addition to the City, could have financial problems
leading to requests for additional New York State assistance during the State's
1994-95 fiscal year and thereafter.  The potential impact on the State of such
requests by localities is not included in the projections of the State's
receipts and disbursements in the State's 1994-95 fiscal year.

      Fiscal difficulties experienced by the City of Yonkers ("Yonkers")
resulted in the creation of the Financial Control Board for the City of Yonkers
(the "Yonkers Board") by New York State in 1984. The Yonkers Board is charged
with oversight of the fiscal affairs of Yonkers.  Future actions taken by the
Governor or the Legislature to assist Yonkers could result in allocation of New
York State resources in amounts that cannot yet be determined.

      Municipalities and school districts have engaged in substantial short-term
and long-term borrowings.  In 1992, the total indebtedness of all localities in
New York State was approximately $35.2 billion, of which $19.5 billion was debt
of New York City (excluding $5.9 billion in MAC debt); a small portion
(approximately $71.6 million) of the $35.2 billion of indebtedness represented
borrowing to finance budgetary deficits and was issued pursuant to enabling New
York State legislation.  State law requires the Comptroller to review and make
recommendations concerning the budgets of those local government units other
than New York City authorized by State law to issue

                                       40
<PAGE>
 
debt to finance deficits during the period that such deficit financing is
outstanding.  Seventeen localities had outstanding indebtedness for deficit
financing at the close of their fiscal year ending in 1992.

      From time to time, federal expenditure reductions could reduce, or in some
cases eliminate, federal funding of some local programs and accordingly might
impose substantial increased expenditure requirements on affected localities.
If New York State, New York City or any of the Authorities were to suffer
serious financial difficulties jeopardizing their respective access to the
public credit markets, the marketability of notes and bonds issued by localities
within New York State could be adversely affected.  Localities also face
anticipated and potential problems resulting from certain pending litigation,
judicial decisions and long-range economic trends.  The longer-range problems of
declining urban population, increasing expenditures and other economic trends
could adversely affect localities and require increasing New York State
assistance in the future.

STANDBY COMMITMENTS

      In order to enhance the liquidity, stability or quality of municipal
obligations, the Prime Obligations, Money Market, Tax-Exempt Diversified, Tax-
Exempt California and Tax-Exempt New York Portfolios each may acquire the right
to sell a security to another party at a guaranteed price and date.  Such a
right to resell may be referred to as a put, demand feature or "standby
commitment", depending on its characteristics.  The aggregate price which a
Portfolio pays for securities with standby commitments may be higher than the
price which otherwise would be paid for the securities.  Standby commitments may
not be available or may not be available on satisfactory terms.

      Standby commitments may involve letters of credit issued by domestic or
foreign banks supporting the other party's ability to purchase the security from
the Portfolio.  The right to sell may be exercisable on demand or at specified
intervals, and may form part of a security or be acquired separately by the
Portfolio.  In considering whether a security meets a Portfolio's quality
standards, the Adviser will look to the creditworthiness of the party providing
the Portfolio with the right to sell as well as the quality of the security
itself.

      The Portfolios value municipal obligations which are subject to standby
commitments at amortized cost.  The exercise price of the standby commitments is
expected to approximate such amortized cost.  No value is assigned to the
standby commitments for purposes of determining a Portfolio's net asset value.
Since the value of a standby commitment is dependent on the ability of the
standby commitment writer to meet its obligation to

                                       41
<PAGE>
 
repurchase, the policy of each Portfolio that may enter into standby commitment
transactions is to enter into such transactions only with banks, brokers or
dealers which represent a minimal risk of default.  The duration of standby
commitments will not be a factor in determining the weighted average maturity of
a Portfolio.

      Management of the Trust understands that the Internal Revenue Service has
issued a favorable revenue ruling to the effect that, under specified
circumstances, a registered investment company will be the owner of tax-exempt
municipal obligations acquired subject to a put option.  Institutional Tax-
Exempt Assets, the predecessor company of which Tax-Exempt Diversified Portfolio
and Tax-Exempt California Portfolio were series, has received a ruling from the
Internal Revenue Service to the effect that it is considered the owner of the
municipal obligations subject to standby commitments so that the interest on
such instruments will be tax-exempt income to it.  The Internal Revenue Service
has subsequently announced that it will not ordinarily issue advance ruling
letters as to the identity of the true owner of property in cases involving the
sale of securities or participation interests therein if the purchaser has the
right to cause the security, or the participation interest therein, to be
purchased by either the seller or a third party.  Each of the Tax-Exempt
Diversified, Tax-Exempt California and Tax-Exempt New York Portfolios intends to
take the position that it is the owner of any municipal obligations acquired
subject to a standby commitment or acquired or held with certain other types of
put rights and that its distributions of tax-exempt interest earned with respect
to such municipal obligations will be tax-exempt for its unitholders.  There is
no assurance that standby commitments will be available to a Portfolio nor has
any Portfolio assumed that such commitments will continue to be available under
all market conditions.


                             INVESTMENT LIMITATIONS

      The following restrictions may not be changed with respect to any
Portfolio without the approval of the majority of outstanding voting securities
of that Portfolio (which, under the Investment Company Act and the rules
thereunder and as used in the Prospectus and this Statement of Additional
Information, means the lesser of (1) 67% of the units of that Portfolio present
at a meeting if the holders of more than 50% of the outstanding units of that
Portfolio are present in person or by proxy, or (2) more than 50% of the
outstanding units of that Portfolio).  Investment restrictions that involve a
maximum percentage of securities or assets shall not be considered to be
violated unless an excess over the percentage occurs immediately after, and is
caused by, an acquisition or encumbrance of securities or assets of, or
borrowings by or on behalf of, a

                                       42
<PAGE>
 
Portfolio, with the exception of borrowings permitted by Investment Restriction
(4).

      Accordingly, the Trust may not, on behalf of any Portfolio:

      (1)  purchase for any one Portfolio the securities of any one issuer,
      other than obligations issued or guaranteed by the U.S. Government, its
      agencies or instrumentalities, if immediately after such purchase, more
      than 5% of the value of such Portfolio's total assets would be invested in
      such issuer, except that (a) up to 25% of the value of its total assets
      may be invested without regard to such 5% limitation, and (b) such 5%
      limitation shall not apply to repurchase agreements collateralized by
      obligations of the U.S. Government, its agencies or instrumentalities.
      This restriction does not, however, apply to any Portfolio classified as
      a non-diversified company under the Investment Company Act;

      (2)  purchase securities if such purchase would cause more than 25% in the
      aggregate of the market value of the total assets of a Portfolio to be
      invested in the securities of one or more issuers having their principal
      business activities in the same industry, provided that there is no
      limitation with respect to, and each Portfolio reserves freedom of action,
      when otherwise consistent with its investment policies, to concentrate its
      investments in obligations issued or guaranteed by the U.S. Government,
      its agencies or instrumentalities, obligations (other than commercial
      paper) issued or guaranteed by U.S. banks and U.S. branches of foreign
      banks and repurchase agreements and securities loans collateralized by
      such U.S. Government obligations or such bank obligations.  (For the
      purposes of this restriction, state and municipal governments and their
      agencies and authorities are not deemed to be industries, and telephone
      companies are considered to be a separate industry from water, gas or
      electric utilities, personal credit finance companies and business credit
      finance companies are deemed to be separate industries and wholly owned
      finance companies are considered to be in the industry of their parents if
      their activities are primarily related to financing the activities of
      their parents).  Notwithstanding the foregoing, the Money Market Portfolio
      will invest more than 25% of the value of its total assets in bank
      obligations (whether foreign or domestic) except that if adverse economic
      conditions prevail in the banking industry the Money Market Portfolio may,
      for defensive purposes, temporarily invest less than 25% of the value of
      its total assets in bank obligations;

                                       43
<PAGE>
 
      (3)  make loans, except (a) through the purchase of debt obligations in
      accordance with each Portfolio's investment objective and policies, (b)
      through repurchase agreements with banks, brokers, dealers and other
      financial institutions, and (c) loans of securities;

      (4)  borrow money, except (a) as a temporary measure, and then only in
      amounts not exceeding 5% of the value of the applicable Portfolio's total
      assets or (b) from banks, provided that immediately after any such
      borrowing all borrowings of the applicable Portfolio do not exceed one-
      third of such Portfolio's total assets.  No purchases of securities will
      be made if such borrowings exceed 5% of the value of the applicable
      Portfolio's assets.  The exceptions to this restriction are not for
      investment leverage purposes but are solely for extraordinary or emergency
      purposes or to facilitate management of the Portfolios by enabling the
      Trust to meet redemption requests when the liquidation of portfolio
      instruments is deemed to be disadvantageous or not possible.  If due to
      market fluctuations or other reasons the total assets of a Portfolio fall
      below 300% of its borrowings, the Trust will promptly reduce the
      borrowings of such Portfolio in accordance with the Investment Company
      Act;

      (5)  mortgage, pledge or hypothecate any assets except to secure permitted
      borrowings;

      (6)  purchase or sell real estate (excluding securities secured by real
      estate or interests therein), securities issued by real estate investment
      trusts, commodities, commodity contracts or oil or gas or other mineral
      exploration or development programs;

      (7)  invest in companies for the purposes of exercising control or
      management;

      (8)  act as an underwriter of securities, (except as the Trust may be
      deemed to be an underwriter under the Securities Act of 1933 in connection
      with the purchase and sale of portfolio instruments in accordance with a
      Portfolio's investment objective and portfolio management policies),
      purchase securities on margin (except for delayed delivery or when issued
      transactions or such short-term credits as are necessary for the clearance
      of transactions), make short sales of securities or maintain a short
      position or invest in or write puts, calls or combinations thereof (except
      that the Trust may, on behalf of a Portfolio, acquire puts in connection
      with the acquisition of a debt instrument); and

                                       44
<PAGE>
 
      (9)  purchase for any one Portfolio the securities of any issuer if such
      purchase would cause more than 10% of the voting securities of such issuer
      to be held by a Portfolio, except that up to 25% of the value of its total
      assets may be invested without regard to this 10% limitation.  This
      restriction does not, however, apply to any Portfolio classified as a
      nondiversified company under the Investment Company Act.

      In addition, as a non-fundamental policy, the Portfolios may not:

      Purchase, hold or deal in real estate (including real estate limited
partnerships) or oil, gas or mineral leases, although a Portfolio may purchase
and sell securities that are secured by real estate or interests therein and may
purchase mortgage-related securities and may hold and sell real estate acquired
by a Portfolio as a result of the ownership of securities.

      Pursuant to SEC Rule 2a-7, the Prime Obligations, Government, Treasury
Obligations, Money Market, Federal and Treasury Instruments Portfolios may not
invest more than 5% of their total assets in the securities of any one issuer
(except U.S. Government securities or repurchase agreements collateralized by
such securities).  A Portfolio may, however, invest more than 5% of its total
assets in the First Tier Securities of a single issuer for a period of up to
three business days after the purchase thereof, although such Portfolio may not
make more than one such investment at any time.  Each Portfolio, other than the
Tax-Exempt Diversified Portfolio, Tax-Exempt California Portfolio and Tax-Exempt
New York Portfolio (the "Tax-Exempt Portfolios"), may only purchase "First Tier
Securities" as defined below.  Securities which are rated in the highest short-
term rating category by at least two Nationally Recognized Statistical Rating
Organizations ("NRSROs") are "First Tier Securities".  Securities rated in the
top two short-term rating categories by at least two major rating agencies, or
if only one NRSRO has assigned a rating, by that NRSRO, but which are not First
Tier Securities.  Pursuant to SEC Rule 2a-7 the foregoing operating policies are
not applicable to the Tax-Exempt Portfolios.  Immediately after the acquisition
of any put by the Prime Obligations, Money Market, Treasury Obligations,
Treasury Instruments, Government or Federal Portfolio, not more than 5% of such
Portfolio's total assets may be invested in securities issued by or subject to
puts from the same issuer.  However, this limitation will not apply to the
issuer of unconditional puts if the Portfolio does not have more than 10% of its
total assets invested in securities issued by or subject to unconditional puts
from such issuer.  NRSROs include S&P, Moody's, Fitch Investors Services, Inc.,
Duff and Phelps, Inc., IBCA Limited and its affiliate IBCA Inc., and Thomson
BankWatch, Inc.  For a description of their rating categories, see Appendix A.

                                       45
<PAGE>
 
Furthermore, each Portfolio, except the Treasury Obligations, Treasury
Instruments, Government and Federal Portfolios may make equity investments in
similar registered investment companies.

      Pursuant to SEC Rule 2a-7, immediately after the acquisition of any put by
a Tax-Exempt Portfolio, not more than 5% of the Portfolio's total assets may be
invested in securities issued by or subject to puts from the same issuer.
However, this limitation applies only with respect to 75% of each Tax-Exempt
Portfolio's total assets.  In addition, this limitation will not apply to the
issuer of unconditional puts if the Portfolio does not have more than 10% of its
total assets invested in securities issued by or subject to unconditional puts
from such issuer.  Each Tax-Exempt Portfolio will operate in accordance with
this operating policy which complies with SEC Rule 2a-7.

      "Value" for the purposes of all investment restrictions shall mean the
value used in determining a Portfolio's net asset value.  "U.S. Government
securities" shall mean securities issued or guaranteed by the U.S. Government or
any of its agencies, authorities or instrumentalities.

                          THE ADVISER, DISTRIBUTOR AND
                                 TRANSFER AGENT

THE ADVISER

     GSAM, a separate operating division of Goldman Sachs, acts as the
investment adviser to the Portfolios. Under the Advisory Agreement between
Goldman Sachs on behalf of GSAM and the Trust on behalf of the Portfolios, GSAM,
subject to the supervision of the Board of Trustees of the Trust and in
conformity with the stated policies of each Portfolio, acts as investment
adviser and directs the investments of the Portfolios. In addition, GSAM
administers the Portfolios' business affairs and, in connection therewith,
furnishes the Trust with office facilities and (to the extent not provided by
the Trust's custodian, transfer agent, or other organizations) clerical
recordkeeping and bookkeeping services and maintains the financial and account
records required to be maintained by the Trust. As compensation for these
services and for assuming expenses related thereto, the Trust pays GSAM a fee,
computed daily and paid monthly at an annual rate of .35% of each Portfolio's
average daily net assets. Pursuant to the Advisory Agreement, GSAM has agreed to
reduce or otherwise limit the daily expenses (excluding fees paid to Service
Organizations, taxes, interest, brokerage and litigation, indemnification and
other extraordinary expenses) of each Portfolio, on an annualized basis, to .43%
of the average daily net assets of that Portfolio. The amount of such reductions
or limits, if any, will be calculated monthly and will be based on the
cumulative difference between a Portfolio's estimated annualized expense ratio
and the expense limit for that Portfolio. This amount shall be reduced by any
prior payments related to the current fiscal year. GSAM has also voluntarily
agreed not to impose all or a portion of its advisory fee and/or to reduce or
otherwise limit the Money Market, Federal, Treasury Instruments and Tax-Exempt
Diversified Portfolio's annual total operating expenses to .36%, .26%, .21% and
 .31%, respectively, of average daily net assets and for each other Portfolio to
 .41% of average daily net assets.

    The Trust, on behalf of each Portfolio, is responsible for all expenses
other than those expressly borne by GSAM under the Portfolios' Advisory
Agreement. The expenses borne by Units of each Portfolio include, without
limitation, the fees payable to GSAM, the fees and expenses of the Trust's
custodian, fees and expenses of the Trust's transfer agent, filing fees for the
registration or qualification of Units under federal or state securities laws,
expenses of the organization of the Trust, taxes (including income and excise
taxes, if any), interest, costs of liability insurance, fidelity bonds,
indemnification or contribution, any costs, expenses or losses arising out of
any liability of, or claim for damages or other relief asserted against, the
Trust for violation of any law, legal and auditing and tax fees and expenses
(including the cost of legal and

                                       52
<PAGE>
 
certain accounting services rendered by employees of Goldman Sachs with respect
to the Trust), expenses of preparing and setting in type prospectuses,
statements of additional information, proxy material, reports and notices, the
printing and distribution of the same to Unitholders and regulatory authorities,
compensation and expenses of its "non-interested" Trustees, and extraordinary
expenses incurred by the Trust. In the event that the expenses of a Portfolio
(including the fees payable to GSAM, but excluding interest, taxes, brokerage
commissions, litigation and indemnification expenses and other extraordinary
expenses) for any fiscal year exceed the limits set by certain state securities
administrators, GSAM will reduce its fee payable on behalf of such Portfolio by
the amount of such excess but only to the extent of the Portfolio's fee.
Repayment of any excess amounts will be made on a monthly basis. The most
restrictive expense limitation currently applicable to each Portfolio is 2.5% of
the first $30 million of a Portfolio's average annual net assets, 2.0% of the
next $70 million of such assets and 1.5% of such assets in excess of $100
million.

    The Advisory Agreement entered into on behalf of the Portfolios was most
recently approved by the Board of Trustees, including the"non-interested"
Trustees, on April 26, 1994 and by the unitholders of each Portfolio (other than
the Treasury Instruments and Tax-Exempt New York Portfolios) on April 19, 1990
and by the unitholders of the Treasury Instruments and Tax-Exempt New York
Portfolios on June 3, 1991. The Advisory Agreement will remain in effect until
June 30, 1995, and will continue in effect thereafter only if such continuance
is specifically approved at least annually by the Trustees or by a vote of a
majority of the outstanding voting securities of the particular Portfolio., as
defined in the Investment Company Act, and, in either case, by a majority of
"non-interested" Trustees.

    Goldman Sachs has authorized any of its directors, partners, officers and
employees who has been elected or appointed as a Trustee or officer of the Trust
to serve in the capacities in which he or she has been elected and appointed.

    For the fiscal years ended December 31, 1994, December 31, 1993 and December
31, 1992 the amount of the advisory fee incurred by each Portfolio then in
existence was as follows:

addition, GSAM assumed certain expenses related to the operations of each
Portfolio during various periods of 1994 to the extent such expenses would have
caused each Portfolio's total expenses to exceed, on an annualized basis,
certain contractual or voluntary expense limitations. Had these expenses not
been assumed, $635,085, $301,326, $371,456, $150,525, $526,310, $326,417,

     Each Portfolio may use any name derived from the name "Goldman Sachs" only
so long as the Advisory Agreement remains in effect. The Advisory Agreement also
provides that it shall terminate automatically if assigned and that it may be
terminated with respect to any particular Portfolio without penalty by vote of a
majority of the Trustees or a majority of the outstanding voting securities of
that Portfolio on 60 days' written notice to GSAM or by GSAM without penalty at
any time on 90 days' written notice to the Trust.

    In managing the Tax-Exempt Diversified Portfolio, the Tax-Exempt California
Portfolio and the Tax-Exempt New York Portfolio, GSAM will draw upon the
extensive research generated by Goldman Sachs' Municipal Credit Group. The
Credit Group's research team continually reviews current information regarding
the issuers of municipal and other tax-exempt securities, with particular focus
on long-term creditworthiness, short-term liquidity, debt service costs,
liability structures, and administrative and economic characteristics.

THE DISTRIBUTOR AND TRANSFER AGENT

    Goldman Sachs acts as principal underwriter and distributor of each
Portfolio's units. The Distribution Agreement between Goldman Sachs and the
Trust was most recently approved by the Trustees on April 26, 1994. Goldman
Sachs also serves as the Portfolios' transfer agent. Goldman Sachs provides
customary transfer agency services to the Portfolios, including the handling of
unitholder communications, the processing of unitholder transactions, the
maintenance of unitholder account records, payment of dividends and
distributions and related functions. For these services, Goldman Sachs receives
 .04% (on an annualized basis) of the average daily net assets with respect

                                       55
<PAGE>
 
to each Portfolio. Goldman Sachs may from time to time agree that the fee it
would otherwise be entitled to receive under its transfer agency agreement will
be reduced.

    For the fiscal year ended December 31, 1994, the Prime Obligations, Money
Market, Treasury Obligations, Treasury Instruments, Government, Federal, Tax-
Exempt Diversified, Tax-Exempt California and Tax-Exempt New York Portfolios

    Goldman Sachs is one of the largest international investment banking firms
in the United States. Founded in 1869, Goldman Sachs is a major player among
investment banking and brokerage firms providing a broad range of financing and
investing services both in the United States and abroad. As of November 30,
1994, Goldman Sachs and its consolidated subsidiaries had assets of
approximately $54.6 billion and partners' capital of $1.8 billion. Goldman Sachs
became registered as an investment adviser in 1981. As of January 31, 1995,
Goldman Sachs, together with its affiliates, acted as investment adviser,
administrator or distributor for approximately $48.7 billion in total assets.

    
DISTRIBUTION AND AUTHORIZED DEALER SERVICE PLANS (ILA CLASS B UNITS ONLY)

AUTHORIZED DEALER SERVICE PLAN
==============================

       As described in the prospectus, the Prime Obligations Portfolio with
respect to its ILA Class B Units has adopted a non-Rule 12b-1 Authorized Dealer
Service Plan (an "Authorized Dealer Service Plan") pursuant to which Goldman
Sachs and Authorized Dealers are compensated for the provision of personal and
account maintenance services.  The Authorized Dealer Service Plan has been
approved by the Board of Trustees, including a majority of the non-interested
Trustees who have no direct or indirect financial interest in the Authorized
Dealer Service Plan, at a meeting held on January 30, 1996.  With respect to its
ILA Class B Units, the Prime Obligations Portfolio's Authorized Dealer Service
Plan provides for the compensation for personal and account maintenance services
at an annual rate of up to 0.25% of the Portfolio's average daily net assets
attributable to ILA Class B Units.

     The Authorized Dealer Service Plan will remain in effect until June 1, 1997
and from year to year thereafter, provided that the continuance of each service
plan is approved annually by a majority vote of the Trustees of the Trust,
including a majority of the non-interested Trustees who have no direct or
indirect financial interest in the Authorized Dealer Service Plan.  All material
amendments of the Authorized Dealer Service Plan must also be approved by the
Trustees of the Trust in the manner described above.  The Authorized Dealer
Service Plan may be terminated at any time as to the Prime Obligations Portfolio
without payment of any penalty by a vote of a majority of the non-interested
Trustees of the Trust or by vote of a majority of the outstanding voting
securities of the Prime Obligations Portfolio.  The Trustees of the Trust have
determined that in their judgment there is a reasonable likelihood that the
Authorized Dealer Service Plan will benefit the Prime Obligations Portfolio and
its ILA Class B Unitholders.

     CLASS B DISTRIBUTION PLAN.  As described in the Prospectus, the Trust has
adopted, on behalf of the Prime Obligations Portfolio, a distribution plan (the
"Class B Plan") pursuant to Rule 12b-1 under the Investment Company Act with
respect to ILA Class B Units.  See "Distribution and Authorized Dealer Service
Plans" in the Prospectus.

     The Class B Plan was approved on January 30, 1996 on behalf of the Trust by
a majority vote of the Trust's Board of Trustees, including a majority of the
Trustees who are not interested persons of the Trust and have no direct or
indirect financial interest in the Class B Plan, cast in person at a meeting
called for the purpose of approving the Class B Plan.  The Class B Plan was
approved by the sole initial unitholder of the Class B Units of the Prime
Obligations Portfolio on January 30, 1996.

     With respect to the Prime Obligations Portfolio, the compensation payable
under the Class B Plan is equal to 0.75% per annum of the average daily net
assets attributable to ILA Class B Units of that Portfolio.  The fees received
by Goldman Sachs under the Class B Plan and contingent deferred sales charge on
ILA Class B Units may be sold by Goldman Sachs as distributor to entities which
provide financing for payments to Authorized Dealers in respect of sales of ILA
Class B Units.  To the extent such fee is not paid to such dealers, Goldman
Sachs may retain such fee as compensation for its services and expenses of
distributing the Prime Obligations Portfolio's ILA Class B Units.  If such fee
exceeds its expenses, Goldman Sachs may realize a profit from these
arrangements.

     The Class B Plan is a compensation plan which provides for the payment of a
specified distribution fee without regard to the distribution expenses actually
incurred by Goldman Sachs.  If the Class B Plan were terminated by the Trust's
Board of Trustees and no successor plan were adopted, the Prime Obligations
Portfolio would cease to make distribution payments to Goldman Sachs and Goldman
Sachs would be unable to recover the amount of any of its unreimbursed
distribution expenditures.

     Under the Class B Plan, Goldman Sachs, as distributor of the Portfolio's
ILA Class B Units, will provide to the Board of Trustees for its review, and the
Board will review at least quarterly, a written report of the services provided
and amounts expended by Goldman Sachs under the Class B Plan and the purposes
for which such services were performed and expenditures were made.

     The Class B Plan will remain in effect with respect to the Prime
Obligations Portfolio from year to year, provided such continuance is approved
annually by a majority vote of the Board of Trustees, including a majority of
the non-interested Trustees.  A Class B Plan may not be amended to increase
materially the amount to be spent for the services described therein as to the
Prime Obligations Portfolio without approval of a majority of the outstanding
ILA Class B Unitholders of that Portfolio.  All material amendments of the Class
B Plan must also be approved by the Board of Trustees of the Trust in the manner
described above.  With respect to the Prime Obligations Portfolio, a Class B
Plan may be terminated at any time without payment of any penalty by a vote of
the majority of the non-interested Trustees or by vote of a majority of the
outstanding voting securities of the ILA Class B Units of that Portfolio.  So
long as a Class B Plan is in effect, the selection and nomination of non-
interested Trustees shall be committed to the discretion of the non-interested
Trustees.  The Trustees have determined that in their judgment there is a
reasonable likelihood that the Class B Plan will benefit the Prime Obligations
Portfolio and its respective ILA Class B Unitholders.     

                            PORTFOLIO TRANSACTIONS

    GSAM places the portfolio transactions of the Portfolios and of all other
accounts managed by GSAM for execution with many firms. GSAM uses its best
efforts to obtain execution of portfolio transactions at prices which are
advantageous to each Portfolio and at reasonable competitive spreads or (when a
disclosed commission is being charged) at reasonably competitive commission
rates. In seeking such execution, GSAM will use its best judgment in evaluating
the terms of a transaction, and will give consideration to various relevant
factors, including without limitation the size and type of the transaction, the
nature and character of the market for the security, the confidentiality,

                                       56
<PAGE>
 
speed and certainty of effective execution required for the transaction, the
general execution and operational capabilities of the broker-dealer, the general
execution and operational capabilities of the firm, the reputation, reliability,
experience and financial condition of the firm, the value and quality of the
services rendered by the firm in this and other transactions, and the
reasonableness of the spread or commission, if any. Securities purchased and
sold by the Portfolios are generally traded in the over-the-counter market on a
net basis (i.e., without commission) through broker-dealers and banks acting for
their own account rather than as brokers, or otherwise involve transactions
directly with the issuer of such securities.

    Goldman Sachs is active as an investor, dealer and/or underwriter in many
types of municipal and money market instruments. Its activities in this regard
could have some effect on the markets for those instruments which the Portfolios
buy, hold or sell. An order has been granted by the SEC under the Investment
Company Act which permits the Portfolios to deal with Goldman Sachs in
transactions in certain taxable securities in which Goldman Sachs acts as
principal. As a result, the Portfolios may trade with Goldman Sachs as principal
subject to the terms and conditions of such exemption.

    Under the Investment Company Act, the Portfolios are prohibited from
purchasing any instrument of which Goldman Sachs is a principal underwriter
during the existence of an underwriting or selling syndicate relating to such
instrument, absent an exemptive order (the order referred to in the preceding
paragraph will not apply to such purchases) or the adoption of and compliance
with certain procedures under such Act. The Trust has adopted procedures which
establish, among other things, certain limitations on the amount of debt
securities that may be purchased in any single offering and on the amount of the
Trust's assets that may be invested in any single offering. Accordingly, in view
of Goldman Sachs' active role in the underwriting of debt securities, a
Portfolio's ability to purchase debt securities in the primary market may from
time to time be limited.

    In certain instances there may be securities which are suitable for more
than one Portfolio as well as for one or more of the other clients of GSAM.
Investment decisions for each Portfolio and for GSAM's other clients are made
with a view to achieving their respective investment objectives. It may develop
that a particular security is bought or sold for only one client even though it
might be held by, or bought or sold for, other clients. Likewise, a particular
security may be bought for one or more clients when one or more other clients
are selling that same security. Some simultaneous transactions are inevitable
when several clients receive investment advice from the same investment adviser,
particularly when the same security is suitable for the investment objectives of
more than one client.

                                       57
<PAGE>
 
When two or more clients are simultaneously engaged in the purchase or sale of
the same security, the securities are allocated among clients in a manner
believed to be equitable to each. It is recognized that in some cases this
system could have a detrimental effect on the price or volume of the security in
a particular transaction as far as a Portfolio is concerned. Each Fund believes
that over time its ability to participate in volume transactions will produce
better executions for the Portfolios.

                                NET ASSET VALUE

    The net asset value per unit of each Portfolio is determined by the
Portfolios' custodian as of the close of regular trading on the New York Stock
Exchange (normally 4:00 p.m. New York time) on each Business Day.  A
Business Day means any day on

                                       58
<PAGE>
 
which the New York Stock Exchange is open, except for days on which Chicago,
Boston or New York banks are closed for local holidays. Such holidays include:
New Year's Day, Martin Luther King Day, President's Day, Good Friday, Memorial
Day, the Fourth of July, Labor Day, Columbus Day, Thanksgiving Day and Christmas
Day.

    Each Portfolio's securities are valued using the amortized cost method of
valuation in an effort to maintain a constant net asset value of $ 1.00 per
unit, which the Board of Trustees has determined to be in the best interest of
the Portfolios and their unitholders. This method involves valuing a security at
cost on the date of acquisition and thereafter assuming a constant accretion of
a discount or amortization of a premium to maturity, regardless of the impact of
fluctuating interest rates on the market value of the instrument. While this
method provides certainty in valuation, it may result in periods during which
value, as determined by amortized cost, is higher or lower than the price a
Portfolio would receive if it sold the instrument. During such periods, the
yield to an investor in a Portfolio may differ somewhat from that obtained in a
similar investment company which uses available market quotations to value all
of its portfolio securities. During periods of declining interest rates, the
quoted yield on units of a Portfolio may tend to be higher than a like
computation made by a fund with identical investments utilizing a method of
valuation based upon market prices and estimates of market prices for all of its
portfolio instruments. Thus, if the use of amortized cost by a Portfolio
resulted in a lower aggregate portfolio value on a particular day, a prospective
investor in the Portfolio would be able to obtain a somewhat higher yield if he
or she purchased units of the Portfolio on that day, than would result from
investment in a fund utilizing solely market values, and existing investors in
the Portfolio would receive less investment income. The converse would apply in
a period of rising interest rates

    The Trustees have established procedures designed to stabilize, to the
extent reasonably possible, each Portfolio's price per unit as computed for the
purpose of sales and redemptions at $1.00. Such procedures include review of
each Portfolio by the Trustees, at such intervals as they deem appropriate, to
determine whether the Portfolio's net asset value calculated by using available
market quotations (or an appropriate substitute which reflects market
conditions) deviates from $1.00 per unit based on amortized cost, as well as
review of methods used to calculate the deviation. If such deviation exceeds 1/2
of 1%, the Trustees will promptly consider what action, if any, will be
initiated. In the event the Trustees determine that a deviation exists which may
result in material dilution or other unfair results to investors or existing
unitholders, they will take such corrective action as they regard to be
necessary and appropriate, including the sale of portfolio

                                       59
<PAGE>
 
instruments prior to maturity to realize capital gains or losses or to shorten
average portfolio maturity; withholding part or all of dividends or payment of
distributions from capital or capital gains; redemptions of units in kind; or
establishing a net asset value per unit by using available market quotations or
equivalents. In addition, in order to stabilize the net asset value per unit at
$1.00 the Trustees have the authority (1) to reduce or increase the number of
units outstanding on a pro rata basis, and (2) to offset each unitholder's pro
rata portion of the deviation between the net asset value per unit and $1.00
from the unitholder's accrued dividend account or from future dividends. Each
Portfolio may hold cash for the purpose of stabilizing its net asset value per
unit. Holdings of cash, on which no return is earned, would tend to lower the
yield on such Portfolio's units.

    In order to continue to use the amortized cost method of valuation each
Portfolio's investments, including repurchase agreements, must be U.S. dollar-
denominated instruments which the Trustees determine present minimal credit
risks and which are at the time of acquisition rated by the requisite number of
nationally recognized statistical rating organizations in one of the two highest
short-term rating categories or, in the case of any instrument that is not so
rated, of comparable quality as determined by GSAM and confirmed by the Board of
Trustees. Also, each Portfolio must maintain a dollar-weighted average portfolio
maturity (not more than 90 days) appropriate to its objective of maintaining a
stable net asset value of $1.00 per unit and, not purchase any instrument with a
remaining maturity of more than thirteen months. However, a Portfolio may also,
consistent with the provisions of the above-mentioned rule, invest in securities
with a maturity of more than thirteen months, if (i) the security is a variable
or floating security with certain demand and interest rate reset features and
(ii) the security, except in the case of a Tax-Exempt Portfolio, is a First Tier
security.

    The proceeds received by each Portfolio for each issue or sale of its units,
and all net investment income, realized and unrealized gain and proceeds
thereof, subject only to the rights of creditors, will be specifically allocated
to such Portfolio and constitute the underlying assets of that Portfolio. The
underlying assets of each Portfolio will be segregated on the books of account,
and will be charged with the liabilities in respect to such Portfolio and with a
share of the general liabilities of the Trust. Expenses with respect to the
Portfolios are to be allocated in proportion to the net asset values of the
respective Portfolios except where allocations of direct expenses can otherwise
be fairly made. In addition, within each Portfolio, ILA Units, ILA Service Units
and ILA Administration Units will be subject to different expense structures
(see "Organization and Capitalization").

                                  REDEMPTIONS

    The Trust may suspend the right of redemption of units of a Portfolio and
may postpone payment for any period: (i) during which the New York Stock
Exchange is closed other than customary weekend and holiday closings or during
which trading on the New York Stock Exchange is restricted, (ii) when the SEC
determines that a state of emergency exists which may make payment or transfer
not reasonably practicable, (iii) as the SEC may by order permit for the
protection of the unitholders of the Trust or (iv) at any other time when the
Trust may, under applicable laws and regulations, suspend payment on the
redemption of the Portfolio's units.

    The Trust agrees to redeem units of each Portfolio solely in cash up to the
lesser of $250,000 or 1% of the net asset value of the Portfolio during any 90-
day period for any one unitholder. The Trust reserves the right to pay other
redemptions, either total or partial, by a distribution in kind of securities
(instead of cash) from the applicable Portfolio's portfolio. The securities
distributed in such a distribution would be valued at the same value as that
assigned to them in calculating the net asset value of the units being redeemed.
If a unitholder receives a distribution in kind, he or she should expect to
incur transaction costs when he or she converts the securities to cash.


                        CALCULATION OF YIELD QUOTATIONS

    Each Portfolio's yield quotations are calculated by a standard method
prescribed by the rules of the SEC. Under this method, the yield quotation is
based on a hypothetical account having a balance of exactly one unit at the
beginning of a seven-day period.

    Yield, effective yield and tax-equivalent yield are calculated separately
for ILA Units, ILA Administration Units and ILA Service Units. Each type of unit
is subject to different fees and expenses and may have differing yields for the
same period.

    The yield quotation is computed as follows: the net change, exclusive of
capital changes (i.e., realized gains and losses from the sale of securities and
unrealized appreciation and depreciation), in the value of a hypothetical pre-
existing account having a balance of one unit at the beginning of the base
period is determined by dividing the net change in account value by the value of
the account at the beginning of the base period. This base period return is then
multiplied by 365/7 (366/7 in the event of a leap year) with the resulting yield
figure carried to the nearest 100th of 1%. Such yield quotation shall take into
account all fees that are charged to a Portfolio.

                                       61
<PAGE>
 
    Each Portfolio also may advertise a quotation of effective yield for a 7-
calendar day period. Effective yield is computed by compounding the unannualized
base period return determined as in the preceding paragraph by adding 1 to that
return, raising the sum to the 365/7 (366/7 in the event of a leap year) power
and subtracting one from the result, according to the following formula:

           Effective Yield = [(base period return + 1)/(365/7)/] - 1

    The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
Portfolios may also advertise a tax-equivalent yield which is computed by
dividing that portion of a Portfolio's yield (as computed above) which is tax-
exempt by one minus a stated income tax rate and adding the quotient to that
portion, if any, of the yield of the Portfolio that is not tax-exempt.

    Unlike bank deposits or other investments which pay a fixed yield or return
for a stated period of time, the return for a Portfolio will fluctuate from time
to time and does not provide a basis for determining future returns. Return is a
function of portfolio quality, composition, maturity and market conditions as
well as of the expenses allocated to each Portfolio. The return of a Portfolio
may not be comparable to other investment alternatives because of differences in
the foregoing variables and differences in the methods used to value portfolio
securities, compute expenses and calculate return.

    The yield, effective yield and tax-equivalent yield of each Portfolio with
respect to ILA Units, ILA Administration Units and ILA Service Units for the
seven-day period ended December 31, 1994 were as follows:

    The quotations of tax-equivalent yield set forth above for the seven-day
period ended December 31, 1994 are based on a federal marginal tax rate of
39.6%.

    With respect to the Tax-Exempt California Portfolio, a California State
personal income tax rate of 11.0% is being assumed in addition to the 39.6%
federal tax rate, for a combined tax rate of 46.2%. With respect to the Tax-
Exempt New York Portfolio, the tax equivalent yields are being shown under two
scenarios. The first scenario assumes a federal marginal tax rate of 39.6% and a
New York State personal income tax rate of 7.875%, for a combined tax rate of
44.4%. The second scenario assumes a New York City personal income tax rate of
4.46% in addition to the above federal and New York, State tax rates, for a
combined tax rate of 47.1%. The combined tax rates assume full deductibility of
state and, if applicable, city taxes in computing federal tax liability.

                                TAX INFORMATION

    Each Portfolio has qualified and has elected or intends to elect to be
treated and to qualify as a regulated investment company under Subchapter M of
the Internal Revenue Code of 1986, as amended, (the "Code"). Such qualification
does not involve supervision of management or investment practices or policies
by any governmental agency or bureau.

    In order to qualify as a regulated investment company, each Portfolio must,
among other things, (a) derive at least 90% of its annual gross income from
dividends, interest, payments with respect to securities loans and gains from
the sale or other disposition of stock or securities or certain other
investments (the "90% Test"); (b) derive less than 30% of its annual gross
income from the sale or other disposition of stock or securities or certain
other investments held less than three months; and (c) diversify its holdings so
that, at the end of each quarter of its taxable year, (i) at least 50% of the
market value of the Portfolio's total gross assets is represented by cash and
cash items (including receivables), U.S. Government securities, securities of
other regulated investment companies and other securities limited, in respect of
any one issuer, to an amount not greater in value than 5% of the value of the
Portfolio's total assets and 10% of the outstanding voting securities of such
issuer, and (ii) not more than 25% of the value of the Portfolio's total assets
is invested in the securities (other than U.S. Government securities and
securities of other regulated investment companies) of any one issuer or two or
more issuers controlled by the Portfolio and engaged in the same, similar or
related trades or businesses. For purposes of these requirements, participation
interests will be treated as securities, and the issuer will be identified on
the basis of

                                       65
<PAGE>
 
market risk and credit risk associated with any particular interest. Certain
payments received with respect to such interests, such as commitment fees and
certain facility fees, may not be treated as income qualifying under the 90%
test.

    Each Portfolio, as a regulated investment company, will not be subject to
federal income tax on any of its net investment income and net realized capital
gains that are distributed to unitholders with respect to any taxable year,
provided that the Portfolio distributes at least 90% of its investment company
taxable income (generally all of its net taxable income other than the excess of
net long-term capital gain over net short-term capital loss) for such year and,
in the case of any Portfolio that earns tax-exempt interest, at least 90% of the
excess of the tax-exempt interest it earns over certain disallowed deductions. A
Portfolio will be subject to federal income tax at regular corporate rates on
any investment company taxable income or net capital gain that it does not
distribute for a taxable year. In order to avoid a 4% federal excise tax, each
Portfolio must distribute (or be deemed to have distributed) by December 31 of
each calendar year at least 98% of its taxable ordinary income for such year, at
least 98% of the excess of its capital gains over its capital losses (computed
on the basis of the one-year period ending on October 31 of such year, unless it
elects to use a calendar year period), and all taxable ordinary income and the
excess of capital gains over capital losses for the previous year that were not
distributed in such year and on which the Portfolio paid no federal income tax.

    Dividends paid by a Portfolio from taxable net investment income (including
gain attributable to accrued market discount and a portion of the discount on
certain stripped tax-exempt obligations and their coupons) and the excess of net
short-term capital gain over net long-term capital loss will be treated as
ordinary income in the hands of unitholders. Such distributions will not qualify
for the corporate dividends-received deduction. Dividends paid a Portfolio from
the excess of net long-term capital gain over net short-term capital loss are
taxable to unitholders as long-term capital gain, regardless of the length of
time the units of a Portfolio have been held by such unitholders, and also will
not qualify for the corporate dividends-received deduction. A Portfolio's net
realized capital gains for a taxable year are computed by taking into account
realized capital losses, including any capital loss carryforward of that
Portfolio.

    Distributions paid by the Tax-Exempt Diversified, Tax-Exempt California and
Tax-Exempt New York Portfolios from tax-exempt interest received by them and
properly designated will generally be exempt from federal income tax, provided
that at least 50% of the value of each Portfolio's total assets at the close of
each quarter of its taxable year consists of tax-exempt obligations

                                       66
<PAGE>
 
(not including units of other regulated investment companies that may pay 
exempt-interest dividends, because such units are not treated as tax-exempt
obligations for this purpose). Distributions paid by the other Portfolios from
any tax-exempt interest they may receive will not be tax-exempt, because they
will not satisfy the 50% requirement described in the preceding sentence. A
portion of any tax-exempt distributions may constitute tax preference items and
may give rise to, or increase liability under, the alternative minimum tax for
particular unitholders. In addition, all tax-exempt distributions of the
Portfolios will be considered in computing the "adjusted current earnings"
preference item of their corporate unitholders in determining the corporate
alternative minimum tax and the corporate environmental tax. To the extent that
the Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New York
Portfolios invest in certain short-term instruments, including repurchase
agreements, the interest on which is not exempt from Federal income tax, any
distributions of income from such investments will be taxable to unitholders as
ordinary income. All or substantially all of any interest on indebtedness
incurred directly or indirectly to purchase or carry units of the Portfolio will
generally not be deductible. The availability of tax-exempt obligations and the
value of the Portfolios may be affected by restrictive tax legislation enacted
in recent years.

    In purchasing municipal obligations, the Tax-Exempt Diversified, Tax-Exempt
California and Tax-Exempt New York Portfolios rely on opinions of nationally-
recognized bond counsel for each issue as to the excludability of interest on
such obligations from gross income for federal income tax purposes and, where
applicable, the tax-exempt nature of such interest under the personal income tax
laws of a particular state. These Portfolios do not undertake independent
investigations concerning the tax-exempt status of such obligations, nor do they
guarantee or represent that bond counsels' opinions are correct.

    Distributions of net investment income and net realized capital gains will
be taxable as described above, whether received in units or in cash. Unitholders
electing to receive distributions in the form of additional units will have a
cost basis in each unit so received equal to the amount of cash they would have
received had they elected to receive cash.

    Certain Portfolios may be subject to foreign withholding taxes with respect
to their investments in certain securities of foreign entities. These taxes may
be reduced under the terms of applicable U.S. income tax treaties, and each
Portfolio intends to satisfy any procedural requirements to qualify for benefits
under these treaties. Although no Portfolio anticipates that more than 50% of
the value of its total assets at the close of a taxable year will be composed of
securities of foreign corporations, if the 50% requirement were satisfied, a
Portfolio

                                       67
<PAGE>
 
could make an election under Code Section 853 to permit its unitholders to claim
a credit or deduction on their federal income tax returns for their pro rata
portion of qualified taxes paid by that Portfolio in foreign countries. In the
event such an election is made, unitholders will be required to include their
pro rata share of such taxes in gross income and will be entitled to claim a
foreign tax credit or deduction with respect to such taxes, subject to certain
limitations under the Code. Unitholders who are precluded from taking such
credits or deductions will nevertheless be taxed on their pro rata share of the
foreign taxes included in their gross income, unless they are otherwise exempt
from federal income tax.

    Each Portfolio will be required to report to the Internal Revenue Service
all taxable distributions except in the case of certain exempt unitholders.
Under the backup withholding provisions of Code Section 3406, all such
distributions may be subject to withholding of federal income tax at the rate of
31% in the case of nonexempt unitholders who fail to furnish the Portfolio with
their taxpayer identification number and with certain required certifications or
if the Internal Revenue Service or a broker notifies a Portfolio that the number
furnished by the unitholder is incorrect or that the unitholder is subject to
backup withholding as a result of failure to report interest or dividend income.
However, any taxable distributions from the Tax-Exempt Diversified, Tax-Exempt
California and Tax-Exempt New York Portfolios will not be subject to backup
withholding if the Portfolio reasonably estimates that at least 95% of its
distributions will be exempt-interest dividends. The Portfolios may refuse to
accept an application that does not contain any required taxpayer identification
number or certification that the number provided is correct or that the investor
is an exempt recipient. If the withholding provisions are applicable, any such
distributions, whether taken in cash or reinvested in units, will be reduced by
the amounts required to be withheld. Investors may wish to consult their tax
advisers about the applicability of the backup withholding provisions.

    All distributions (including exempt-interest dividends) whether received in
units or cash, must be reported by each unitholder on the unitholder's federal
income tax return. The Portfolios will inform unitholders of the federal income
tax status of their distributions after the end of each calendar year,
including, in the case of the Tax-Exempt Diversified, Tax-Exempt California and
Tax-Exempt New York Portfolios, the amounts that qualify as exempt-interest
dividends and any portions of such amounts that constitute tax preference items
under the federal alternative minimum tax. Unitholders who receive exempt-
interest dividends and have not held their units of the applicable Portfolio for
its entire taxable year may have designated as tax-exempt or as a tax preference
item a percentage of their distributions which is not exactly equal to a

                                       68
<PAGE>
 
proportionate share of the amount of tax-exempt interest or tax preference
income earned during the period of their investment in such Portfolio. Each
unitholder should consult his or her own tax advisor to determine the tax
consequences of an investment in a Portfolio in the unitholder's own state and
locality.

    Different tax treatment, including penalties on certain excess contributions
and deferrals, certain pre-retirement and post-retirement distributions, and
certain prohibited transactions is accorded to accounts maintained as qualified
retirement plans. Unitholders should consult their tax advisers for more
information. 

    The foregoing discussion relates solely to U.S. federal income tax law as it
applies to U.S. persons (i.e., U.S. citizens and residents and U.S. domestic
corporations, partnerships, trusts and estates) subject to tax under such law.
The discussion does not address special tax rules applicable to certain classes
of investors, such as tax-exempt entities, insurance companies and financial
institutions. Each unitholder who is not a U.S. person should consult his or her
tax adviser regarding the U.S. and non-U.S. tax consequences of ownership of
units of a Portfolio, including the possibility that such a unitholder may be
subject to a U.S. withholding tax at a rate of 30% (or at a lower rate under an
applicable U.S. income tax treaty) on certain distributions or to backup
withholding on certain payments if a current IRS Form W-8 or acceptable
substitute is not on file with the Portfolios.

STATE AND LOCAL

    The Portfolios may be subject to state or local taxes in jurisdictions in
which the Portfolios may be deemed to be doing business. In addition, in those
states or localities which have income tax laws, the treatment of the Trust and
its unitholders under such laws may differ from their treatment under Federal
income tax laws, and investment in the Portfolios may have tax consequences for
unitholders different from those of a direct investment in the Portfolios
securities. Unitholders should consult their own tax advisers concerning these
matters. For example, in such states or localities it may be appropriate for
unitholders to review with their tax advisers the state income and, if
applicable, intangibles tax consequences of investments by the Portfolios in
securities issued by the particular state or the U.S. Government or its various
agencies or instrumentalities, because many states exempt from personal income
tax distributions by regulated investment companies from interest on obligations
of the particular state or on direct U.S. Government obligations and/or exempt
from intangibles tax the value of the units of such companies attributable to
such obligations, subject to certain state-specific requirements and/or
limitations.

                                       69

    Assuming that each Portfolio qualifies as a regulated investment company for
federal income tax purposes, each Portfolio, as a series of a Massachusetts
business trust, will not be subject to any income, franchise or corporate excise
tax in Massachusetts. Provided that they qualify as regulated investment
companies and incur no federal income tax liability, the Portfolios may still be
subject to New York State and City minimum taxes, which are small in amount.

    California State Taxation. The following discussion of California tax law
assumes that the Portfolio will be qualified as a regulated investment company
under Subchapter M of the Code and will be qualified thereunder to pay exempt-
interest dividends. The Portfolio intends to qualify for each taxable year under
California law to pay "exempt interest dividends" which will be exempt from the
California personal income tax.

    Individual unitholders of the Tax-Exempt California Portfolio who reside in
California will not be subject to California personal income tax on
distributions received from the Portfolio to the extent such distributions are
exempt-interest dividends attributable to interest on obligations the interest
on which is exempt from California personal income tax provided that the
Portfolio satisfies the requirement of California law that at least 50% of its
assets at the close of each quarter of its taxable year be invested in such
obligations and properly designates such exempt-interest dividends under
California Law. Distributions from the Tax-Exempt California Portfolio which are
attributable to sources other than those described in the second preceding
sentence will generally be taxable to such unitholders as ordinary income.
Moreover, California legislation which incorporates Subchapter M of the Code
provides that capital gain dividends may be treated as long-term capital gains.
Such gains are currently subject to personal income tax at ordinary income tax
rates. Capital gains that are retained by the Portfolio will be taxed to that
Portfolio, and California residents will receive no California personal income
tax credit for such tax. Distributions other than exempt-interest dividends are
includable in income subject to the California alternative minimum tax.

    Distributions from investment income and long-term and short-term capital
gains will generally not be excluded from taxable income in determining
California corporate franchise taxes for corporate unitholders and will be
treated as ordinary dividend income for such purposes. In addition, such
distributions may be includable in income subject to the alternative minimum
tax.

    Interest on indebtedness incurred or continued by unitholders to purchase or
carry units of the Tax-Exempt California Portfolio will not be deductible for
California personal income tax purposes.

                                       70
<PAGE>
 
    In addition, any loss realized by a unitholder of the Tax-Exempt California
Portfolio upon the sale of units held for six months or less may be disallowed
to the extent of any exempt-interest dividends received with respect to such
units. Moreover, any loss realized upon the redemption of units within six
months from the date of purchase of such units and following receipt of a long-
term capital gains distribution will be treated as long-term capital loss to the
extent of such long-term capital gains distribution. Finally, any loss realized
upon the redemption of units within thirty days before or after the acquisition
of other units of the same Portfolio may be disallowed under the "wash sale"
rules.z

    New York City and State Taxation. Individual unitholders who are residents
of New York State will be able to exclude for New York State income tax purposes
that portion of the distributions received from the Tax-Exempt New York
Portfolio which is derived from interest on obligations of New York State and
its political subdivisions and of Puerto Rico, the U.S. Virgin Islands and Guam,
provided that at least 50% of the value of the assets of the Portfolio are
invested at the close of each quarter of its taxable year in obligations of
issuers the interest on which is excluded from gross income for federal income
tax purposes. Individual unitholders who are residents of New York City will
also be able to exclude such income for New York City income tax purposes.
Interest on indebtedness incurred or continued by a shareholder to purchase or
carry shares of the Tax-Exempt New York Portfolio is not deductible for New York
State or New York City personal income tax purposes.

    Capital gains that are retained by the Tax-Exempt New York Portfolio will be
taxed to that Portfolio, and New York State and New York City residents will
receive no New York income tax credit for federal, New York State or New York
City taxes on such capital gains. Capital gains that are distributed by the Tax-
Exempt New York Portfolio will be treated as capital gains for New York State
and City income tax purposes in the hands of New York State and New York City
residents.

    Both New York State and New York City impose a minimum tax on minimum
taxable income. A portion of the distributions of the Tax-Exempt New York
Portfolio may constitute tax-preference items includable in such minimum taxable
income.

    Unitholders should consult their tax advisers about the application of the
provisions of tax law described in this Statement of Additional Information in
light of their particular tax situations.

    This discussion of the tax treatment of the Portfolio and its unitholders is
based on the tax laws in effect as of the date of this Statement of Additional
Information.

                        ORGANIZATION AND CAPITALIZATION

    The Trust is a Massachusetts business trust established under the laws of
The Commonwealth of Massachusetts by a Declaration of Trust dated December 6,
1978. The Tax-Exempt Diversified Portfolio and Tax-Exempt California Portfolio
are the successors to separate series of Goldman Sachs Institutional Tax-Exempt
Assets which was formed pursuant to a Declaration of Trust on March 23, 1982.
Each of these Portfolios became a series of the Trust pursuant to a
reorganization which occurred on April 30, 1990. On December 13, 1990 the
Trustees authorized the establishment of the Treasury Instruments and Tax-Exempt
New York Portfolios.

    Each unitholder is deemed to have expressly assented and agreed to the terms
of the Declaration of Trust and is deemed to be party thereto. The authorized
capital of the Trust consists of an unlimited number of units of beneficial
interest. The Trustees have authority under the Declaration of Trust to create
and classify units of beneficial interest in separate series without further
action by unitholders. The Declaration of Trust further authorizes the Trustees
to classify or reclassify any series or portfolio of units into one or more
classes. The Trustees have authorized the issuance of four classes of units of
the Prime Obligations Portfolio and three classes of units of each other
portfolio: ILA Units, ILA Administration Units, ILA Service Units and in the
case of the Prime Obligations Portfolio, ILA Class B Units.

    Each ILA Unit, ILA Administration Unit, ILA Service Unit and Class B Unit of
a Portfolio is entitled to one vote per unit; however, separate votes will be
taken by each Portfolio or class (or by more than one Portfolio or class voting
as a single class if similarly affected) on matters affecting only that
individual Portfolio or class (or those affected Portfolios or classes) or as
otherwise required by law. Fractional units are entitled to proportionate
fractional votes. Units are freely transferable and have no preemptive,
subscription or conversion rights. All units issued and outstanding are fully
paid and nonassessable by the Trust. The Declaration of Trust provides for
unitholder voting only for the election or removal of one or more Trustees, if a
meeting is called for that purpose, and for certain other designated matters.
The Trust does not generally hold annual or other meetings of unitholders. The
units of the Portfolios have non-cumulative voting rights, which means that the
holders of more than 50% of the units voting for the election of Trustees can
elect 100% of the Trustees if they choose to do so, and, in such event, the
holders of the remaining less than 50% of the units voting for the election of
Trustees will not be able to elect any person or persons to the Board of
Trustees. Each Trustee serves until the next meeting of unitholders, if any,

                                       72
<PAGE>
 
    called for the purpose of electing or reelecting such Trustee or successor
to such Trustee, and until the election and qualification of such successor, if
any, or until such Trustee sooner dies, resigns, retires or is removed by the
unitholders or two-thirds of the Trustees.

    Each ILA Unit, ILA Administration Unit, ILA Service Unit and ILA Class B
Unit of a Portfolio represents an equal proportionate interest in the assets
belonging to that Portfolio. It is contemplated that most units will be held in
accounts of which the record owner is a bank or other institution acting,
directly or through an agent, as nominee for its customers who are beneficial
owners of the units or another organization designated by such bank or
institution. ILA Units may be purchased for accounts held in the name of an
institution that is not compensated by the Trust for services provided to the
institution's investors. ILA Administration Units may be purchased for accounts
held in the name of an institution that provides certain account administration
services to its customers, including maintenance of account records, processing
orders to purchase, redeem and exchange ILA Administration Units. ILA
Administration Units of each Portfolio bear the cost of administration fees at
the annual rate of up to .15 of 1% of the average daily net assets of such
Units. ILA Service Units may be purchased for accounts held in the name of an
institution that provides certain account administration and unitholder liaison
services to its customers, including maintenance of account records and
processing orders to purchase, redeem and exchange ILA Service Units, responding
to customer inquiries and assisting customers with investment procedures. ILA
Service Units bear the cost of service fees at the annual rate of up to .40 of
1% of the average daily net assets of such Units. (Institutions that provide
services to holders of ILA Administration or Service Units are referred to in
this Prospectus as "Service Organizations"). ILA Class B Units of the Prime
Obligations Portfolio are sold subject to a contingent deferred sales charge of
up to 5.0% through brokers and dealers who are members of the National
Association of Securities Dealers, Inc. and certain other financial services
firms that have sales arrangements with Goldman Sachs. ILA Class B Units of the
Prime Obligations Portfolio bear the cost of distribution (Rule 12b-1) fees at
the aggregate rate of up to 0.75% of the average daily net assets attributable
to ILA Class B Units. ILA Class B Units of the Prime Obligations Portfolio also
bear the cost of an Authorized Dealer Service Plan at an annual rate of up to
0.25% of the average daily net assets of the Prime Obligations Portfolio
attributable to ILA Class B Units.

    It is possible that an institution or its affiliate may offer different
classes of units to its customers and thus receive different compensation with
respect to different classes of units of the same Portfolio. In the event a
Portfolio is

                                       73
<PAGE>
 
    distributed by salespersons or any other persons, they may receive different
compensation with respect to different classes of units of the Portfolio. ILA
Service Units and ILA Administration Units each have certain exclusive voting
rights on matters relating to their respective plans. Except as described above,
the four classes of units are identical. Certain aspects of the Units may be
altered, after advance notice to unitholders, if it is deemed necessary in order
to satisfy certain tax regulatory requirements.

                       UNITHOLDER AND TRUSTEE LIABILITY

    The Trust is an entity of the type commonly known as a "Massachusetts
business trust," which is the form in which many mutual funds are organized.
Under Massachusetts law, unitholders of such a trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
trust. The Declaration of Trust contains an express disclaimer of unitholder
liability for acts or obligations of the Trust. Notice of such disclaimer will
normally be given in each agreement, obligation or instrument entered into or
executed by the Trust or the Trustees. The Declaration of Trust provides for
indemnification by the relevant Portfolio for any loss suffered by a unitholder
as a result of an obligation of the Portfolio. The Declaration of Trust also
provides that the Trust shall, upon request, assume the defense of any claim
made against any unitholder for any act or obligation of the Trust and satisfy
any judgment thereon. Thus, the risk of a unitholder incurring financial loss on
account of unitholder liability is limited to circumstances in which a Portfolio
is unable to meet its obligations. The Trustees believe that, in view of the
above, the risk of personal liability of unitholders is not material.

    The Declaration of Trust provides that the Trustees of the Trust shall not
be liable for any action taken by them in good faith, and that they shall be
fully protected in relying in good faith upon the records of the Trust and upon
reports made to the Trust by persons selected in good faith by the Trustees as
qualified to make such reports. The Declaration of Trust further provides that
the Trustees will not be liable for errors of judgment or mistakes of fact or
law. The Declaration of Trust provides that the Trust will indemnify Trustees
and officers of the Trust against liabilities and expenses reasonably incurred
in connection with litigation in which they may be involved because of their
positions with the Trust, unless it is determined in the

                                       75

manner provided in the Declaration of Trust that they have not acted in good
faith in the reasonable belief that, in the case of conduct in their official
capacity with the Trust, such conduct was in the best interests of the Trust
and, in all other cases, that the conduct was at least not opposed to the best
interests of the Trust (and in the case of any criminal proceeding, they had no
reasonable cause to believe that the conduct was unlawful). However, nothing in
the Declaration of Trust or the By-Laws protects or indemnifies Trustees or
officers against any liability to which they would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of their office.

                     SERVICE PLAN (ILA Service Units Only)     

    The Trust, on behalf of each Portfolio, has adopted a service plan (the
"Plan") with respect to the ILA Service Units which authorize the Portfolios to
compensate Service Organizations for providing certain account administration
and personal account maintenance services to their customers who are or may
become beneficial owners of such units. Pursuant to the Plan, the Trust, on
behalf of each Portfolio, enters into agreements with Service Organizations
which purchase ILA Service Units on behalf of their customers ("Service
Agreements"). Under such Service Agreements the Service Organizations may: (a)
act, directly or through an agent, as the sole unitholder of record and nominee
for all customers, (b) maintain account records for each customer who
beneficially owns ILA Service Units, (c) answer questions and handle
correspondence from customers regarding their accounts, (d) process customer
orders to purchase, redeem and exchange ILA Service Units, and handle the
transmission of funds representing the customers' purchase price or redemption
proceeds, (e) issue confirmations for transactions in units by customers, (f)
provide facilities to answer questions from prospective and existing investors
about ILA Service Units, (g) receive and answer investor correspondence,
including requests for prospectuses and statements of additional information,
(h) display and make prospectuses available on the Service Organization's
premises, (i) assist customers in completing application forms, selecting
dividend and other account options and opening custody accounts with the Service
Organization, and (j) act as liaison between customers and the Trust, including
obtaining information from the Trust, working with the Trust to correct errors
and resolve problems and providing statistical and other information to the
Trust. As compensation for such services, the Trust on behalf of each Portfolio
pays each Service Organization a service fee in an amount up to .40% (on an
annualized basis) of the average daily net assets of the ILA Service Units of
each Portfolio attributable to or held in the name of such Service Organization
for its customers; provided, however, that the fee paid for personal and account
maintenance services shall not exceed .25% of such average daily net assets.

    For the fiscal years ended December 31, 1994, December 31, 1993 and December
31, 1992, with respect to each Portfolio, the amount of the service fees paid by
each Portfolio then in existence to Service Organizations was as follows:

/(1)/ ILA Service Unit activity commenced August 1992.
/(2)/ ILA Service Unit activity has not commenced operations.

    The Trust has adopted each Plan pursuant to Rule 12b-l under the Investment
Company Act in order to avoid any possibility that payments to the Service
Organizations pursuant to the Service Agreements might violate the Investment
Company Act. Rule 12b-l, which was adopted by the Securities and Exchange
Commission under the Investment Company Act, regulates the circumstances under
which an investment company such as the Trust may bear expenses associated with
the distribution of its securities. In particular, such an investment company
cannot engage directly or indirectly in financing any activity which is
primarily intended to result in the sale of securities issued by the company
unless it has adopted a plan pursuant to, and complies with the other
requirements of, such Rule. The Trust believes that fees paid for the services
provided in the Plan and described above are not expenses incurred primarily for
effecting the distribution of ILA Service Units. However, should such payments
be deemed by a court or the Securities and Exchange Commission to be
distribution expenses, such payments would be duly authorized by the Plan.

    The Glass-Steagall Act prohibits all entities which receive deposits from
engaging to any extent in the business of issuing, underwriting, selling or
distributing securities, although institutions such as national banks are
permitted to purchase and sell securities upon the order and for the account of
their customers. Should future legislative or administrative action or judicial
or administrative decisions or interpretations prohibit or restrict the
activities of one or more of the Service Organizations in connection with the
Trust, such Service Organizations might be required to alter materially or
discontinue the services performed under their Service Agreements. If one or
more of the Service Organizations were restricted from effecting purchases or
sales of ILA Service Units automatically pursuant to pre-authorized
instructions, for example, effecting such

                                       79
<PAGE>
 
transactions on a manual basis might affect the size and/or growth of the
Portfolios. In addition, state securities laws on this issue may differ from the
interpretations of federal law expressed herein and banks and other financial
institutions purchasing ILA Service Units on behalf of their customers may be
required to register as dealers pursuant to state law. Any such alteration or
discontinuance of services could require the Trustees of the Trust to consider
changing the Trust's method of operations or providing alternative means of
offering ILA Service Units to customers of such Service Organizations, in which
case the operation of the Trust, its size and/or its growth might be
significantly altered. It is not anticipated, however, that any alteration of
the Trust's operations would have any effect on the net asset value per unit or
result in financial losses to any unitholder.

    Conflict of interest restrictions (including the Employee Retirement Income
Security Act of 1974) may apply to a Service Organization's receipt of
compensation paid by the Trust in connection with the investment of fiduciary
funds in ILA Service Units. Service Organizations, including banks regulated by
the Comptroller of the Currency, the Federal Reserve Board or the Federal
Deposit Insurance Corporation, and investment advisers and other money managers
subject to the jurisdiction of the Securities and Exchange Commission, the
Department of Labor or State Securities Commissions, are urged to consult legal
advisers before investing fiduciary assets in ILA Service Units.

    The Plans were approved by the respective holders of ILA Service Units of
each Portfolio (other than the Tax-Exempt California and Tax-Exempt New York
Portfolios) on June 3, 1991. The Trustees of the Trust, including a majority of
the Trustees who are not interested persons of the Trust and who have no direct
or indirect financial interest in the operation of such Plans or the related
Service Agreements, most recently voted to approve the Plans and Service
Agreements at a meeting called for the purpose of voting on such Plan and
Service Agreements on April 26, 1994. They will remain in effect until April 30,
1995 and will continue in effect thereafter only if such continuance is
specifically approved annually by a vote of the Trustees in the manner described
above. A Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval of the ILA Service
unitholders of the affected Portfolio, and all material amendments of a Plan
must also be approved by the Trustees in the manner described above. A Plan may
be terminated at any time by a majority of the Trustees as described above or by
vote of a majority of the outstanding ILA Service Units of the affected
Portfolio. The Service Agreements may be terminated at any time, without payment
of any penalty, by vote of a majority of the Trustees as described above or by a
vote of a majority of the outstanding ILA Service Units of the affected
Portfolio on not more than 60 days'

                                       80

written notice to any other party to the Service Agreements. The Service
Agreements shall terminate automatically if assigned. So long as the Plans are
in effect, the selection and nomination of those Trustees who are not interested
persons shall be determined by the discretion of the Trust's Nominating
Committee, which consists of all of the non-interested members of the Board of
Trustees. The Trustees have determined that, in their judgment, there Is a
reasonable likelihood that the Plans will benefit the Portfolios and holders of
ILA Service Units of such Portfolios. In the Trustees' quarterly review of the
Plans and Service Agreements, they will consider their continued appropriateness
and the level of compensation provided therein.

                      DESCRIPTION OF SECURITIES RATINGS/1/


MOODY'S INVESTORS SERVICE, INC.

Bond Ratings
- ------------

    Aaa: Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

    Aa: Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than with Aaa securities.

    Moody's applies numerical modifiers, 1, 2, and 3 in the Aa category. The
modifier 1 indicates that the security ranks in the higher end of the Aa
category; the modifier 2 indicates a mid-range ranking; and the modifier 3
indicates that the issue ranks in the lower end of the Aa category.


Short-Term Ratings
- ------------------

    P-1: Issuers have a superior capacity for repayment of short-term promissory
obligations. Prime-1 or P-1 repayment capacity will normally be evidenced by the
following characteristics:

- --------------
/1/ The ratings indicated herein are believed to be the most recent ratings
    available at the date of this Statement of Additional Information for the
    securities listed. Ratings are generally given to securities at the time of
    issuance. While the rating agencies may from time to time revise such
    ratings, they undertake no obligation to do so, and the ratings indicated do
    not necessarily represent ratings which will be given to these securities on
    the date of the Portfolios' taxable year end.

                                      A-1
<PAGE>
 
   .    Leading market positions in well established industries.

   .    High rates of return on funds employed.

   .    Conservative capitalization structures with moderate reliance on debt
        and ample asset protection.

   .    Broad margins in earnings coverage of fixed financial charges and high
        internal cash generation.

   .    Well established access to a range of financial markets and assured
        sources of alternate liquidity.

    P-2: Issuers have a strong capacity for repayment of short-term promissory
obligations. This will normally be evidenced by many of the characteristics
cited above but to a lesser degree. Earnings trends and coverage ratios, while
sound, will be more subject to variation. Capitalization characteristics, while
still appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.

State and Municipal Obligations
- -------------------------------

    Moody's ratings for state and municipal short-term obligations will be
designated Moody's Investment Grade or (MIG). Such ratings recognize the
differences between short-term credit risk and long-term risk. Factors affecting
the liquidity of the borrower and short-term cyclical elements are critical in
short-term ratings, while other factors of major importance in bond risk, long-
term secular trends for example, may be less important over the short run.
Symbols used will be as follows:

    MIG 1 -- This designation denotes best quality. There is present strong
protection by established cash flows, superior liquidity support or demonstrated
broadbased access to the market for refinancing.

    MIG 2 -- This designation denotes high quality. Margins of protection are
ample although not so large as in the preceding group.

    A short-term rating may also be assigned on an issue having a demand
feature. Such ratings will be designated as VMIG to reflect such characteristics
as payment upon periodic demand rather than fixed maturity dates and payment
relying on external liquidity. Additionally, investors should be alert to the
fact that the source of payment may be limited to the external liquidity with no
or limited legal recourse to the issuer in the event the demand is not met VMIG-
1, and VMIG-2 ratings carry the same definitions as MIG-1, and MIG-2,
respectively.

                                      A-2
<PAGE>
 
STANDARD & POOR'S RATINGS GROUP

Bond Ratings
- ------------

    AAA: Bonds rated AAA are highest grade debt obligations. This rating
indicates an extremely strong capacity to pay principal and interest.

    AA: Bonds rated AA also qualify as high-quality obligations. Capacity to pay
principal and interest is very strong, and in the majority of instances they
differ from AAA issues only in small degree.

    PLUS (+) OR MINUS (-): The "AA" rating may be modified by the addition of a
plus or minus sign to show relative standing within the "AA" category.

Short-Term Ratings
- ------------------

    A-1: Standard & Poor's Commercial Paper ratings are current assessments of
the likelihood of timely payment of debts having an original maturity of no more
than 365 days. The A-1 designation indicates that the degree of safety regarding
timely payment is very strong. Those issues determined to possess extremely
strong safety characteristics will be denoted with a plus ( + ) sign
designation.

    A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated "A-1".

MUNICIPAL NOTES

    A Standard & Poor's note rating reflects the liquidity concerns and market
access risks unique to notes. Notes due in 3 years or less will likely receive a
note rating. Notes maturing beyond 3 years will most likely receive a long-term
debt rating. The following criteria will be used in making that assessment.

   .    Amortization schedule (the larger the final maturity relative to other
        maturities the more likely it will be treated as a note).

   .    Source of payment (the more dependent the issue is on the market for its
        refinancing, the more likely it will be treated as a note).

    Note rating symbols are as follows:

    SP-1 -- Very strong or strong capacity to pay principal and interest. Those
issues determined to possess overwhelming safety characteristics will be given a
plus (+) designation.

                                      A-3
<PAGE>
 
    SP-2 -- Satisfactory capacity to pay principal and interest with some
vulnerability to adverse financial and economic changes over the term of the
notes.

    SP-3 -- Speculative capacity to pay principal and interest.

    Standard & Poor's assigns "dual" ratings to all debt issues that have a put
option or demand feature as part of their structure.

    The first rating addresses the likelihood of repayment of principal and
interest as due, and the second rating addresses only the demand feature. The
long-term debt rating symbols are used for bonds to denote the long-term
maturity and the commercial paper rating symbols for the put option (for
example, "AAA/A-1+"). With short-term demand debt, S&P's note rating symbols are
used with the commercial paper rating symbols (for example, "SP-1+/A-1+").

DUFF & PHELPS, INC.

Bond Ratings
- ------------

    AAA: Long-term fixed income securities which are rated AAA are judged to be
of the highest credit quality. The risk factors are negligible, being only
slightly more than for risk-free U.S. Treasury debt.

    AA: Long-term fixed income securities which are rated AA are judged to be of
high credit quality. Protection factors are strong. Risk is modest but may vary
slightly from time to time because of economic conditions.

    Duff & Phelps applies modifiers, AA+ and AA- in the AA category for long-
term fixed income securities. The modifier AA+ indicates that the security ranks
in the higher end of the AA category: the modifier AA indicates a mid-range
ranking; and the modifier AA-indicates that the issue ranks in the lower end of
the AA category.

Short-Term Ratings
- ------------------

    DUFF 1: Commercial paper and certificates of deposit rated Duff 1 are
considered to have a very high certainty of timely payment. Liquidity factors
are considered excellent and are supported by strong fundamental protection
factors. Risk factors are minor.

    DUFF 2: Commercial paper and certificates of deposit rated Duff 2 are
considered to have a good certainty of timely payment. Liquidity factors and
company fundamentals are considered sound. Although ongoing internal funds needs
may enlarge total financing

                                      A-4
<PAGE>
 
requirements, access to capital markets is good and risk factors are small.

    Duff & Phelps applies a plus and minus rating scale, Duff 1 plus, Duff 1 and
Duff 1 minus in the Duff 1 top grade category for commercial paper and
certificates of deposit. The rating Duff 1 plus indicates that the security has
the highest certainty of timely payment, short-term liquidity is clearly
outstanding and safety is just below risk-free U.S. Treasury short-term
obligations; the rating Duff 1 indicates a very high certainty of timely
payment, liquidity factors are excellent and risk factors are minimal; and the
rating Duff 1 minus indicates a high certainty of timely payment, liquidity
factors are strong and risk factors are very small.


                         FITCH INVESTORS SERVICE CORP.

    Eligible Fitch ratings for short-term debt obligations payable on demand or
with original maturities of up to three years, including commercial paper,
certificates of deposit, medium-term notes, and municipal and investment notes
may be rated F-1 or F-2.

    F-1: Short-term debt obligations rated F-1 are considered to be of very
strong credit quality. Those issues determined to possess exceptionally strong
credit quality and having the strongest degree of assurance for timely payment
will be denoted with a plus ("+") sign designation.

    F-2: Short-term debt obligations rated F-2 are considered to be of good
credit quality. Issues assigned this rating have a satisfactory degree of
assurance for timely payment, but the margin of safety is not as great as for
issues assigned "F-1+" and "F-1" ratings.

                          IBCA LIMITED AND IBCA INC.

    A1: Short-term obligations rated A1 are supported by a very strong capacity
for timely repayment. A plus ("+") sign is added to those issues determined to
possess the highest capacity for timely payment.

    A2: Short-term obligations rated A2 are supported by a strong capacity for
timely repayment, although such capacity may be susceptible to adverse changes
in business, economic or financial conditions.

                            THOMSON BANKWATCH, INC.

    AAA: The highest category; indicates a superior ability to repay principal
and interest on a timely basis is very high.

                                      A-5
<PAGE>
 
    AA: The second highest category; indicates a superior ability to repay
principal and interest on a timely basis with limited incremental risk versus
issues rated in the highest category.

Ratings in the AA Long-Term Debt category may include a plus (+) or minus (-)
designation which indicates where within the respective category the issue is
placed.

The TBW Short-Term Ratings apply only to unsecured instruments that have a
maturity of one year or less.

The TBW Short-Term Ratings specifically assess the likelihood of an untimely
payment of principal and interest.

    TBW-1: The highest category; indicates a very high degree of likelihood that
principal and interest will be paid on a timely basis.

    TBW-2: The second highest category; while the degree of safety regarding
timely repayment of principal and interest is strong, the relative degree of
safety is not as high as for issues rated "TBW-1".
