Interest rates represent either the stated coupon rate, annualized yield on
date of purchase for discounted notes, or, for floating rate securities, the
current reset rate, which is based upon current interest rate indices.
 
Maturity dates represent either the stated date on the security, the next
interest reset date for floating rate securities, or the prerefunded date for
those types of securities.
 
The percentages shown for each investment category reflect the value of
investments in that category as a percentage of total net assets.

Goldman Sachs Trust--Financial Square Funds
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
June 30, 1998
(Unaudited)
- ---------------------------------------  ---------------------------------------
1. ORGANIZATION
The Goldman Sachs Trust (the "Trust") is a Delaware business trust registered
under the Investment Company Act of 1940 (as amended) as an open-end management
investment company. The Trust includes the Financial Square Funds, collectively
"the Funds" or individually a "Fund". Financial Square consists of nine
diversified funds: Prime Obligations, Money Market, Premium Money Market,
Treasury Obligations, Treasury Instruments, Government, Federal, Tax-Free Money
Market and Municipal Money Market (inactive as of June 30, 1998). The Financial
Square Funds offer four classes of shares: FST shares, FST Preferred shares,
FST Administration shares and FST Service shares. The investment objective of
the Funds is to maximize current income to the extent consistent with the
preservation of capital and maintenance of liquidity.
 
2. SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of significant accounting policies consistently
followed by the Funds. The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that may affect the reported amounts.
 
A. Investment Valuation--
Each Fund uses the amortized-cost method for valuing portfolio securities which
approximates market value. Under this method, all investments purchased at a
discount or premium are valued by amortizing the difference between the
original purchase price and maturity value of the issue over the period to
maturity.
 
B. Interest Income--
Interest income is determined on the basis of interest accrued, premium
amortized and discount earned.
 
C. Federal Taxes--
It is each Fund's policy to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies and to distribute
each year substantially all investment company taxable and tax-exempt income to
shareholders. Accordingly, no federal tax provisions are required.
 The characterization of distributions to shareholders for financial reporting
purposes is determined in accordance with federal income tax rules. Therefore,
the source of the Funds' distributions may be shown in the accompanying
financial statements as either from or in excess of net investment income or
net realized gain on investment transactions, or from paid-in capital,
depending on the type of book/tax differences that may exist.
 At December 31, 1997, the Funds' tax year end, the following funds had capital
loss carryforwards for U.S. Federal tax purposes of approximately:

</TABLE>
 
D. Deferred Organization Expenses--
Organization-related costs are being amortized on a straight-line basis over a
period of five years.
 
E. Expenses--
Expenses incurred by the Funds that do not specifically relate to an individual
fund are generally allocated to the Funds based on each Fund's relative average
net assets for the period.
 Shareholders of FST Preferred, FST Administration and FST Service shares bear
all expenses and fees paid to service organizations for their services with
respect to such shares.

3. AGREEMENTS
Pursuant to the Investment Management Agreement (the "Agreement"), Goldman
Sachs Asset Management ("GSAM"), a separate operating division of Goldman,
Sachs & Co. ("Goldman Sachs"), manages the portfolios of the Funds, subject to
general supervision by the Trust's Board of Trustees and administers each
Fund's business affairs, including providing facilities. As compensation for
the services rendered under the Investment Management Agreement and the
assumption of the expenses related thereto, GSAM is entitled to a fee, computed
daily and payable monthly, at an annual rate equal to .205% of each Fund's
average daily net assets. These amounts are included in "Accrued expenses and
other liabilities" in the accompanying Statements of Assets and Liabilities.
 For the six months ended June 30, 1998, GSAM has voluntarily agreed to waive a
portion of its management fee. In addition, GSAM has limited certain of each of
the Fund's expenses (excluding management fees, service organization fees,
taxes, interest, brokerage commissions, litigation, indemnification and other
extraordinary expenses) to the extent that such expenses exceed .01% per annum
of the Fund's average daily net assets. The outstanding amounts to be
reimbursed by the Adviser are included in "Other assets" in the accompanying
Statement of Assets and Liabilities where applicable.
 Goldman Sachs serves as Transfer Agent and Distributor of shares of the Funds
pursuant to Transfer Agent and Distribution Agreements and receives no fee.
 The following chart outlines the fee waivers and expense reimbursements for
the six months ended June 30, 1998 and amounts owed to and due from GSAM at

5.LINE OF CREDIT FACILITY
The Funds participate in a $250,000,000 uncommitted, unsecured revolving line
of credit facility to be used solely for temporary or emergency purposes. Under
the most restrictive arrangement, each Fund must own securities having a market
value in excess of 300% of the total bank borrowings. The interest rate on the
borrowings is based on the Federal Funds rate. During the six months ended June
30, 1998, the Funds did not have any borrowings under this facility.
 
6.REPURCHASE AGREEMENTS
During the term of a repurchase agreement, the value of the underlying
securities, including accrued interest, is required to equal or exceed the
value of the repurchase agreement. The underlying securities for all repurchase
agreements are held in safekeeping at a custodian.
 
7.JOINT REPURCHASE AGREEMENT ACCOUNTS
The Funds, together with other registered investment companies having
management agreements with GSAM or its affiliates, transfer uninvested cash
balances into joint accounts, the daily aggregate balances of which are
invested in one or more repurchase agreements.
 At June 30, 1998, the Prime Obligations, Money Market, Premium Money Market,
Treasury Obligations and Government Funds had undivided interests in the
