Market Overview

Goldman Sachs CORE Equity Funds

Dear Shareholder, 

During the review period, events that began in Asia in 1997 continued to roil
financial markets around the world.

 .    Market Review: Global Markets Fluctuate Along With Investor Confidence -
     The arrival of 1998 heralded another step up in the staircase pattern of
     global equity prices. Worries about contagion from Asia and Japan receded
     rapidly from the prior months, and the deflationary influence from the East
     helped cool the U.S. and European economies, thereby lowering bond yields
     and increasing equity valuations. In contrast, the second half of the
     period was marked by a trend of escalating volatility. Political and
     economic woes in Indonesia, Russia and Brazil affected market performance
     around the globe, while the continuing weakness of the Japanese yen placed
     further pressure on the emerging Asian economies. The consequent collapse
     of several hedge funds further upset the financial sector and, in response,
     investors sought security in the form of fixed income investments. 
     
     By period end, equity markets rebounded on renewed confidence that
     concerted action from the G-7, including an easing of rates by the Federal
     Reserve Board, would help avert a global financial meltdown. Markets were
     further boosted by encouraging news out of Japan, which appeared to
     indicate it may finally begin to address its structural problems.

 .    Market Outlook: Optimism Prevails -- We are generally positive on the U.S.
     economy. Over the last decade, global communication has increased,
     resulting from significant technological advances as well as a generally
     stable world political environment. We believe that this trend, combined
     with favorable demographic trends (including the aging of the baby
     boomers), will benefit U.S. companies over the long term. 

     In Europe, with the advent of the single currency, the euro, prospects for
     equities are bright. We believe that the consolidation process within
     industries will continue unabated. As companies strive to lower their costs
     and to dominate in Europe, investors stand to benefit.

     In Japan, it may take some time until we start to see clear signs of a
     recovery. However, the government seems to be moving in the right direction
     by, for example, engineering cuts in taxes. Also, a number of Japanese
     companies, including those that had been reluctant to restructure their
     businesses, have finally come to grips with their problems. This may mean
     that once corporate revenues stop declining further, there could be a
     substantive pick-up in bottom-line earnings for next year. As investors'
     outlook for corporate profit improves, we believe the equity market is
     likely to stabilize and move upward.

     Going forward, macro risks to Asian markets include a slowing of the U.S.
     and European economies and a possible renewed weakness in the yen. We also
     believe that investors will begin to focus on the timing of economic
     recoveries in Asian countries, as well as a possible earnings recovery for
     many companies. Therefore, stock selectivity will become more important in
     the coming year, since not all companies or sectors will participate
     equally in the economic recovery.

     We encourage you to maintain your long term investment program, and look
     forward to serving your investment needs in the years ahead.
     
     Sincerely,

     /s/ David B. Ford                       /s/ John P. McNulty

Performance Overview

CORE U.S. Equity Fund


Dear Shareholder,

We are pleased to report on the performance of the Goldman Sachs CORE U.S.
Equity Fund for the 12-month period ended January 31, 1999.

Performance Review

Over the 12-month period ended January 31, 1999, the Fund's Class A, B, C,
Institutional and Service shares generated annual total returns, without sales
charges, of 26.89%, 26.19%, 26.19%, 27.65% and 27.00%, respectively. These
returns underperformed the 32.48% annualized return of the Fund's benchmark, the
S&P 500 Index. However, all of the Fund's share classes outperformed the 17.35%
average return of its peers, as represented by the Lipper Growth and Income Fund
peer group average. 

The Fund's underperformance versus its benchmark is primarily attributable to
events that took place in the final half of the review period, and particularly
from July through October 1998. The four months ended October were characterized
by a sharp increase in volatility. The spread in returns between the best- and
worst-performing stocks in our universe was two times higher than normal. This
meant that the penalty for not choosing the right stocks was much higher than we
would normally expect.

In addition, during this period, most of the factors in our quantitative model
produced results completely opposite to their long-term averages. For example,
overvalued stocks (especially those with high price/book and high price/earnings
ratios) soundly trounced their more cheaply valued counterparts. In the
large-cap sector, stocks with strong price momentum underperformed stocks with
poor price momentum. 

The qualitative research portion of the Fund's investment
model also produced mixed results, thus negatively impacting performance.

Portfolio Positioning

The CORE investment process analyzes each stock based upon its Value, Momentum
and Risk characteristics as well as a fundamental Research assessment.
Throughout the fiscal year under review, we placed the most emphasis on the
Momentum theme, followed by Research and Value. Risk accounted for about 15% of
a company's expected excess return.

 .    Early in the period under review, all of the four themes that make up the
     model predicted returns as we expected, with Momentum generating the
     highest returns.

 .    Mid-period, as mentioned previously, most of the factors in our model
     produced results completely opposite to their long-term averages.

 .    After performing contrary to our expectations at mid-period, most of our
     model factors returned to a more normal forecasting ability in the final
     months of the period, especially among larger cap stocks. Both Value and
     Momentum produced better-than-average results, while Research was about
     average. The Risk theme, however, generated negative results.

                                                            Performance Overview

The Goldman Sachs CORE U.S. Equity Fund seeks long-term capital growth and
dividend income by investing in a broadly diversified portfolio of large-cap and
blue-chip equity securities representing all major sectors of the U.S. economy.

- --------------------------------------------------------------------------------
                            Core Investment Process
- --------------------------------------------------------------------------------

                               Computer Optimized

 .    Risk management tools designed to minimize industry and style risk.

 .    Emphasis on stock selection with attention to attractive quantitative and
     qualitative ratings.

 .    Construct portfolio with maximum expected return forecast within risk
     guidelines.

                               Research Enhanced

 .    Fundamental Research from Goldman Sachs' Global Investment Research
     Department and other research sources.

 .    Quantitative insights from proprietary multi-factor model rank each stock
     by its value, momentum and risk characteristics.

                                 CORE Process

Result: A risk-managed portfolio grounded by a rigorous quantitative model and
enhanced by fundamental research.

Portfolio Highlights

Noteworthy company performance spanned a diverse group of sectors, including:

 .    Technology holdings Microsoft Corp. (up 136.0%) and Intel Corp. (up 74.2%)
     generated strong returns over the period.

 .    Telecommunications companies AT&T Corp. (up 47.9%), MCI Worldcom, Inc. (up
     122.7%) and BellSouth Corp. (up 50.2%) generated strong performance over
     the review period.

Portfolio Outlook

Returns reverted to a more normal pattern starting in October, both for the
factors we track and for the overall portfolio. Although stock volatility
remains higher than average, we have implemented a few changes in our process to
help ensure a more accurate forecast of portfolio risk versus the benchmark. We
maintain a strong conviction, however, that our model factors have the potential
to generate strong returns over the long term. Cheaper stocks should outpace
more expensive ones, good momentum stocks should do better than poor momentum
stocks, lower risk stocks should perform better than higher risk stocks, as
should those favored by research analysts. 

We thank you for your investment and look forward to your continued confidence.

/6/ Performance data for Institutional shares prior to May 1, 1997 (commencement
    of operations) is that of Class A shares. Class A share performance for such
    period is that of a predecessor separate account (which converted into Class
    A shares) adjusted to reflect the higher fees and expenses applicable to the
    Fund's Class A shares. Although the predecessor separate account was managed
    by Goldman Sachs Asset Management in a manner and pursuant to investment
    objectives in all material respects equivalent to management and investment
    objectives of the CORE Large Cap Growth Fund, the separate account was not
    registered under the Investment Company Act of 1940 (the "Act") and was not
    subject to certain investment restrictions imposed by the Act. If it had
    registered under the Act, performance might have been adversely affected.

CORE Large Cap Growth Fund


Dear Shareholder,

We are pleased to report on the performance of the Goldman Sachs CORE Large Cap
Growth Fund for the 12-month period ended January 31, 1999.

Performance Review

Over the 12-month period ended January 31, 1999, the Fund's Class A, B, C,
Institutional and Service shares generated strong annual total returns, without
sales charges, of 35.10%, 34.07%, 34.04%, 35.54% and 34.85%, respectively. While
these returns underperformed the 42.59% annualized return of the Fund's
benchmark, the Russell 1000 Growth Index, they outperformed the 27.06% annual
total return of the Fund's peers, as represented by the Lipper Growth Fund peer
group average.

The Fund's underperformance versus its benchmark is primarily attributable to
events that took place in the final half of the review period, and particularly
from August through October 1998. During this period, most of the factors in our
quantitative model produced results completely opposite to their long-term
averages. For example, overvalued stocks (especially those with high price/book
and high price/earnings ratios) soundly trounced their more cheaply valued
counterparts. In the large-cap sector, stocks with strong price momentum
underperformed stocks with poor price momentum. 

The qualitative research portion of the Fund's investment model also produced
mixed results, thus negatively impacting performance.

Portfolio Positioning

The CORE investment process analyzes each stock based upon its Value, Momentum
and Risk characteristics as well as a fundamental Research assessment.
Throughout the fiscal year under review, we placed the most emphasis on the
Momentum theme, followed by Research and Value. Risk accounted for about 15% of
a company's expected excess return.

 .    Early in the fiscal year, the position on Momentum, combined with the
     qualitative stock insights provided by Goldman Sachs Global Investment
     Research Department as well as consensus opinions, produced positive
     performance results. Value also helped returns. The Risk theme, however,
     detracted from performance, as higher risk generally fared best in the
     market environment.

 .    Mid-period, as mentioned previously, most of the factors in our model
     produced results completely opposite to their long-term averages.

 .    As we experienced early in the fiscal year, at period end, the Value and
     Momentum themes helped performance, as returns attributable to both were
     higher than average. The Research theme also generated positive results.
     The Risk theme, however, generated negative results, producing returns
     opposite from what we anticipated. 

                                                                               5

Performance Overview

The Goldman Sachs CORE Large Cap Growth Fund seeks long-term capital growth,
primarily by investing in a broadly diversified portfolio of equity securities
that are expected to have better prospects for earnings growth than the growth
rate of the general domestic economy.

Portfolio Highlights

Noteworthy company performance spanned a diverse group of sectors, including:

 .    Healthcare holdings Abbot Laboratories (up 33.0%), Wellpoint Health Net
     Works, Inc. (up 52.7%) and Schering Plough Corp. (up 52.1%) generated
     strong performance over the period.

 .    Microsoft Corp. (up 136.0%) and Intel Corp. (up 74.2%), both technology
     holdings, generated strong returns over the period.

 .    Telecommunications companies AT&T Corp. (up 41.2%) and MCI Worldcom, Inc.
     (up 68.6%) generated positive returns over the review period.

Portfolio Outlook

As always, the Fund remains fully invested in stocks. Our sector weightings and
distribution among size categories are targeted to stay close to those of the
Russell 1000 Growth Index, as are our exposures to other risk factors (such as
dividend yield). Over the long term, our quantitative process has preferred low
price/earnings and low price/book stocks with good momentum characteristics. We
therefore intend to maintain an exposure to these factors. 

We thank you for your investment and look forward to your continued confidence.

Performance Overview

CORE Small Cap Equity Fund

Dear Shareholders, 

We are pleased to report on the performance of the Goldman Sachs CORE Small Cap
Equity Fund for the 12-month period ended January 31, 1999.

Performance Review

Over the 12-month period ended January 31, 1999, the Fund's Class A, B, C,
Institutional and Service shares generated annual total returns, without sales
charges, of -3.97%, -4.64%, -4.64%, -3.64% and -4.07%, respectively. These
returns underperformed the 0.33% annualized return of the Fund's benchmark, the
Russell 2000 Index.

The Fund's underperformance versus its benchmark is primarily attributable to
events that took place in the final half of the review period, and particularly
from July through October 1998. The four months ended October were characterized
by a sharp increase in volatility. The spread in returns between the best- and
worst-performing stocks in our universe was two times higher than normal. This
meant that the penalty for not choosing the right stocks was much higher than we
would normally expect.

At the same time, in the third quarter, the factors we use to predict return
produced results completely opposite of their long-term averages: richly valued
stocks outpaced cheap ones; stocks with poor momentum fared better than those
with good momentum; low beta - but high residual volatility - stocks did well,
as did those that were not favored by research analysts. Thus the
diversification of our models did not help returns.

Portfolio Positioning

The CORE investment process analyses each stock based upon its Value, Momentum
and Risk characteristics as well as a fundamental Research assessment.
Throughout the fiscal year under review, we placed the most emphasis on the
Momentum theme, followed by Research and Value. Risk accounted for about 15% of
a company's expected excess return.

 .    Early in the period under review, of the four themes that make up the
     model, Momentum and Value fared well at forecasting returns among small-cap
     stocks. Although Research's contribution was minimal, it was still
     positive. Finally, with regard to our Risk theme, higher risk stocks
     generated the most positive performance, counter to our expectations.

 .    Mid-period, as mentioned previously, most of the factors in our model
     produced results completely opposite to their long-term averages.

 .    After performing contrary to our expectations at mid-period, Momentum and
     Research returned to a more normal forecasting ability in the final months
     of the period. The Value theme neither helped nor hurt performance in the
     small-cap universe. The Risk theme, however, generated negative results,
     producing returns opposite from what we anticipated.

CORE Large Cap Value Fund

Dear Shareholder,

It is a pleasure to welcome you as a shareholder in the Goldman Sachs CORE Large
Cap Value Fund. This annual report covers the brief period from December 31,
1998, when the Fund was initiated, through January 31, 1999.

Performance Review

Over the one-month period ended January 31, 1999, the Fund's Class A, B, C,
Institutional and Service shares generated cumulative total returns, without
sales charges, of 1.50%, 1.50%, 1.50%, 1.60% and 1.60%, respectively. Over the
same time period, the Fund's benchmark, the Russell 1000 Value Index, generated
a cumulative total return of 0.80%.

Performance over the period was driven by good stock selection among the biggest
names in the index; good stock selection within the finance and utilities
sectors also drove the relative gains.

Portfolio Positioning

The CORE investment process analyzes each stock based upon its Value, Momentum
and Risk characteristics as well as a fundamental Research assessment.
Throughout the period under review, the greatest emphasis was placed on the
Momentum theme, while the least was placed on the Risk theme.

 .    During the period, the Value and Momentum themes helped performance, as
     returns attributable to these themes were higher than average. The Risk
     theme and Research themes, however, generated negative results, producing
     returns opposite from what we anticipated.

Performance Overview


The Goldman Sachs CORE Large Cap Value Fund seeks long-term growth of capital by
investing primarily in a broadly diversified portfolio of equity securities of
large cap U.S. issuers that are selling at low to modest valuations relative to
general market measures.

Portfolio Outlook

As always, the Fund remains fully invested in stocks. Our sector weightings and
distribution among size categories are targeted to stay close to those of the
Russell 1000 Value Index; thus the heaviest weightings are in finance and
utilities. We also seek to mimic the bench- mark in our exposures to other risk
factors (such as dividend yield). Over the long term, our quantitative process
has preferred low price/earnings and low price/book stocks with good Momentum
characteristics that fundamental research analysts consider attractive. We
therefore intend to maintain an exposure to these factors, while also continuing
to prefer lower risk to higher risk stocks.

We thank you for your investment and look forward to your continued confidence.

3 The Cumulative Total Return (with sales charge) is determined by computing the
percentage change in the value of $1,000 invested at the maximum public offering
price for specified periods, assuming reinvestment of all distributions at NAV.
The total return calculation reflects a maximum initial sales charge of 5.5% for
Class A shares, the assumed deferred sales charge for Class B shares (5% maximum
declining to 1% in the sixth year) and the assumed deferred sales charge for
Class C shares (1% if redeemed within 12 months of purchase). The public
offering price of the Class A shares on December 31, 1998 was $10.54 and
represents the NAV plus the maximum sales charge of 5.5%.

The top 10 holdings may not be representative of the Fund's future investments.

Total return figures represent past performance and do not indicate future
results, which will vary. The investment return and principal value of an
investment will fluctuate and, therefore, an investor's shares, when redeemed,
may be worth more or less than their original cost. Performance reflects fee
waivers and expense limitations in effect. In their absence, performance would
be reduced.

Performance Overview

CORE International Equity Fund

Dear Shareholder, 

We are pleased to report on the performance of the Goldman Sachs
CORE International Equity Fund for the 12-month period ended January 31, 1999.

Performance Review 

Over the 12-month period ended January 31, 1999, the Fund's Class A, B, C,
Institutional and Service shares generated annual total returns, without sales
charges, of 8.37%, 8.03%, 8.03%, 9.20% and 8.74%, respectively. These returns
underperformed the 14.73% annualized return of the Fund's benchmark, the Morgan
Stanley Capital International (MSCI) Gross Europe, Australasia, Far East (EAFE)
Index.

The past year has been marked by extremes. Volatility increased dramatically in
the third quarter of 1998, as the effects of Russia's debt crisis spread through
both developing and developed markets. The increased volatility drove investors
to the "safest" assets, primarily large capitalization stocks. Consequently,
during the review period, the usual relationships between value, momentum and
returns broke down. Relative valuations did not help find stocks or countries
that outperformed.

Regional Allocations 

Continental Europe was the most heavily weighted region throughout
the fiscal year under review. More specifically, within Continental Europe, we
favored such countries as Finland, Sweden and Spain. We underweighted the U.K.,
Germany and France, as valuation and momentum factors in these countries were
weak. 

The Fund had an overweight exposure to Japanese equities for most of the review
period, given the country's attractively valued equity market. By the end of
1998, we moved this position to neutral due to weak momentum, unattractive risk
factors and worsened currency-related indicators. Conversely, a neutral position
in Asia (excluding Japan) was moved to an overweight position in view of
attractive valuations, favorable risk factors and good currency-related
indicators.

Sector Allocations

In general, the Fund's sector exposure approximated that of its benchmark, the
MSCI Gross EAFE Index. Slight differences in weightings are a result of the
Fund's bottom-up stock selection process, rather than any economic forecast for
specific sectors.

Portfolio Highlights 

Noteworthy company performance spanned a diverse group of countries and sectors,
including:

 .    Singapore Airlines Ltd. (Singapore, up 68.4%) and Qantas Airways
     (Australia, up 17.9%), both airlines, generated good positive returns.

 .    Banks such as Banca Commercial Italiana (Italy, up 57.8%) and Bank of Tokyo
     Mitsubishi (Japan, up 28.1%) generated good returns over the period.

 .    Health care companies Glaxo Wellcome PLC (U.K., up 27.5%), Hoechst AG
     (Germany, up 26.8%) and Zeneca Group (U.K., up 19.6%) performed well over
     the period.

Performance Summary
January 31, 1999
 
 The following graph shows the value, as of January 31, 1999, of a $10,000 in-
 vestment made (with the maximum sales charge of 5.5%) in Class A shares on
 May 24, 1991 (commencement of operations) of the Goldman Sachs CORE U.S. Eq-
 uity Fund. For comparative purposes, the performance of the Fund's benchmark
 (the Standard and Poor's 500 Index ("S&P 500 Index")) is shown. This perfor-
 mance data represents past performance and should not be considered indica-
 tive of future performance which will fluctuate with changes in market
 conditions. These performance fluctuations will cause an investor's shares,
 when redeemed, to be worth more or less than their original cost. Performance
 of Class B, Class C, Institutional and Service shares will vary from Class A
 due to differences in fees and loads.

Performance Summary
January 31, 1999
 
 
 The following graph shows the value, as of January 31, 1999, of a $10,000 in-
 vestment made (with the maximum sales charge of 5.5% per Class A and contin-
 gent deferred sales charges of 5.0% and 1.0% for Class B and C, respectively
 and at NAV for the Institutional and Service Classes) on August 15, 1997
 (commencement of operations) of the Goldman Sachs CORE International Equity
 Fund. For comparative purposes, the performance of the Fund's benchmark (Mor-
 gan Stanley Gross Europe, Australia, Far East Index ("MS Gross EAFE Index"))
 is shown. This performance data represents past performance and should not be
 considered indicative of future performance which will fluctuate with changes
 in market conditions. These performance fluctuations will cause an investor's
 shares, when redeemed, to be worth more or less than their original cost.

 (a) The aggregate cost for federal income tax purposes is $380,312,871.
 (b) Each index future utilizes a multiplier for each contract with the index
     value at time of purchase in notional par value. The total net notional
     amount and market value at risk are $7,401,325 and $7,438,333, respec-
     tively. The determination of notional amounts does not consider market
     risk factors and therefore notional amounts presented here are indicative
     only of volume of activity and not a measure of market risk.

GOLDMAN SACHS TRUST - CORE EQUITY FUNDS
Notes to Financial Statements
January 31, 1999
 1. ORGANIZATION
 
 Goldman Sachs Trust (the "Trust") is a Delaware business trust registered un-
 der the Investment Company Act of 1940 (as amended) as an open-end, manage-
 ment investment company. The Trust includes the CORE U.S. Equity Fund, CORE
 Large Cap Growth Fund, CORE Small Cap Equity Fund, CORE Large Cap Value and
 the CORE International Equity Fund, collectively the "Funds" or individually
 a "Fund". At January 31, 1999, each Fund offered five classes of shares --
  Class A, Class B, Class C, Institutional and Service.
 
 2. SIGNIFICANT ACCOUNTING POLICIES
 
 The following is a summary of the significant accounting policies consist-
 ently followed by the Funds. The preparation of financial statements in con-
 formity with generally accepted accounting principles requires management to
 make estimates and assumptions that may affect the reported amounts. Certain
 reclassifications have been made to the prior period amounts to conform with
 the current period presentation. Such reclassifications have no effect as
 previously reported net asset values of the Funds.
 
 A. Investment Valuation -- Investments in securities traded on a U.S. or for-
 eign securities exchange or the NASDAQ system are valued daily at their last
 sale or closing price on the principal exchange on which they are traded. If
 no sale occurs, securities are valued at the mean between the closing bid and
 asked prices. Debt securities are valued at prices supplied by an independent
 pricing services, which reflect broker / dealer-supplied valuations or matrix
 pricing systems. Unlisted equity and debt securities for which market quota-
 tions are available are valued at the last sale price on valuation date, or
 if no sale occurs, at the mean between the most recent bid and asked prices.
 Short-term debt obligations maturing in sixty days or less are valued at am-
 ortized cost. Restricted securities, and other securities for which quota-
 tions are not readily available, are valued at fair value using methods
 approved by the Trust's Board of Trustees.
 
 B. Security Transactions and Investment Income -- Security transactions are
 recorded as of the trade date. Realized gains and losses on sales of portfo-
 lio securities are calculated using the identified-cost basis. Dividend in-
 come is recorded on the ex-dividend date. Dividends for which the Fund has
 the choice to receive either cash or stock are recognized as investment in-
 come in an amount equal to the cash dividend. Interest income is recorded on
 the basis of interest accrued, premium amortized and discount earned. It is
 the Funds' policy, where necessary, to accrue for estimated capital gains
 taxes in foreign securities.
 
 C. Foreign Currency Translations -- The books and records of the Funds are
 maintained in U.S. dollars. Amounts denominated in foreign currencies are
 translated into U.S. dollars on the following basis: (i) investment valua-
 tions, foreign currency and other assets and liabilities initially expressed
 in foreign currencies are converted each business day into U.S. dollars based
 upon current exchange rates; and (ii) purchases and sales of foreign invest-
 ments, income and expenses are converted into U.S. dollars based upon cur-
 rency exchange rates prevailing on the respective dates of such transactions.
   Net realized and unrealized gain (loss) on foreign currency transactions
 will represent: (i) foreign exchange gains and losses from the sale and hold-
 ings of foreign currencies; (ii) currency gains and losses between trade date
 and settlement date on investment securities transactions and forward ex-
 change contracts; and (iii) gains and losses from the difference between
 amounts of dividends, interest and foreign withholding taxes recorded and the
 amounts actually received.
 
 D. Forward Foreign Currency Exchange Contracts -- The CORE International Fund
 may enter into forward foreign currency exchange contracts for the purchase
 or sale of a specific foreign currency at a fixed price on a future date as a
 hedge or cross-hedge against either specific transactions or portfolio posi-
 tions. The CORE International Equity Fund may also purchase and sell forwards
 contracts to seek to increase total return. All commitments are "marked-to-
 market" daily at the applicable translation rates and any resulting
 unrealized gains or losses are recorded in the Fund's financial statements.

<PAGE>
 
                                         GOLDMAN SACHS TRUST - CORE EQUITY FUNDS
 Fund realizes gains or losses at the time a forward contract is offset by en-
 try into a closing transaction or extinguished by delivery of the currency.
 Risks may arise upon entering into these contracts from the potential inabil-
 ity of counterparties to meet the terms of their contracts and from unantici-
 pated movements in the value of a foreign currency relative to the U.S.
 dollar.
 
 E. 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 of its investment company taxable
 income and capital gains to its shareholders. Accordingly, no federal tax
 provisions are required.
   The characterization of distributions to shareholders for financial report-
 ing purposes is determined in accordance with income tax rules. Therefore,
 the source of each Fund's distributions may be shown in the accompanying fi-
 nancial statements as either from or in excess of net investment income or
 net realized gain on investment transactions, or from paid-in capital, de-
 pending on the type of book/tax differences that may exist as well as timing
 differences associated with having different book and tax year ends.
   CORE Small Cap Equity, CORE Large Cap Growth and CORE International Equity
 Funds had approximately $19,364,000, $18,495,000 and $14,803,548, respec-
 tively at October 31, 1998 (the Fund's tax year end) of capital loss
 carryforward expiring in 2006 for Federal tax purposes. These amounts are
 available to be carried forward to offset future capital gains to the extent
 permitted by applicable law or regulations.
 
 F. Expenses -- Expenses incurred by the Trust that do not specifically relate
 to an individual fund of the Trust are generally allocated to the funds on a
 straight-line or pro rata basis depending upon the nature of the expense.
   Class A, Class B and Class C shareholders of the Funds bear all expenses
 and fees relating to their respective distribution and service plans. Share-
 holders of Service shares bear all expenses and fees paid to service organi-
 zations for their services with respect to such shares. Effective September
 1, 1998, each class of shares of the Funds separately bears its respective
 class-specific transfer agency fees.
 
 G. Option Accounting Principles -- When the Funds write call or put options,
 an amount equal to the premium received is recorded as an asset and as an
 equivalent liability. The amount of the liability is subsequently marked-to-
 market to reflect the current market value of the option written. When a
 written option expires on its stipulated expiration date or the Funds enter
 into a closing purchase transaction, the Funds realize a gain or loss without
 regard to any unrealized gain or loss on the underlying security, and the li-
 ability related to such option is extinguished. When a written call option is
 exercised, the Funds realize a gain or loss from the sale of the underlying
 security, and the proceeds of the sale are increased by the premium origi-
 nally received. When a written put option is exercised, the amount of the
 premium originally received will reduce the cost of the security which the
 Funds purchase upon exercise. There is a risk of loss from a change in value
 of such options which may exceed the related premiums received.
   Upon the purchase of a call option or a protective put option by the Funds,
 the premium paid is recorded as an investment and subsequently marked-to-mar-
 ket to reflect the current market value of the option. If an option which the
 Funds have purchased expires on the stipulated expiration date, the Funds
 will realize a loss in the amount of the cost of the option. If the Funds en-
 ter into a closing sale transaction, the Funds will realize a gain or loss,
 depending on whether the sale proceeds for the closing sale transaction are
 greater or less than the cost of the option. If the Funds exercise a pur-
 chased put option, the Funds will realize a gain or loss from the sale of the
 underlying security, and the proceeds from such sale will be decreased by the
 premium originally paid. If the Funds exercise a purchased call option, the
 cost of the security which the Funds purchase upon exercise will be increased
 by the premium originally paid.
 
 H. Futures Contracts -- The Funds may enter into futures transactions to
 hedge against changes in interest rates, securities prices, currency exchange
 rates or to seek to increase total return.
   Upon entering into a futures contract, the Funds are required to deposit
 with a broker an amount of cash or securities equal to the minimum "initial
 margin" requirement of the associated futures exchange. Subsequent payments
 for futures
 
                                                                              53

GOLDMAN SACHS TRUST - CORE EQUITY FUNDS
Notes to Financial Statements (continued)

 contracts ("variation margin") are paid or received by the Funds, depending
 on the fluctuations in the value of the contracts, and are recorded for fi-
 nancial reporting purposes as unrealized gains or losses. When contracts are
 closed, the Funds realize a gain or loss which is reported in the Statement
 of Operations.
   The use of futures contracts involve, to varying degrees, elements of mar-
 ket and counterparty risk which may exceed the amounts recognized in the
 Statements of Assets and Liabilities. Changes in the value of the futures
 contract may not directly correlate with changes in the value of the under-
 lying securities. This risk may decrease the effectiveness of the Funds'
 strategies and potentially result in a loss.
 
 3. AGREEMENTS
 
   Pursuant to the Investment Management Agreements ("the Agreements"),
 Goldman Sachs Asset Management ("GSAM"), a separate operating division of
 Goldman, Sachs & Co. ("Goldman Sachs"), serves as the investment adviser for
 CORE Large Cap Growth, CORE Small Cap Equity, CORE Large Cap Value and CORE
 International Equity Fund and Goldman Sachs Funds Management, L.P. ("GSFM"),
 an affiliate of Goldman Sachs, serves as the investment adviser for CORE U.S.
 Equity Fund. Under the Agreements, the respective adviser, subject to the
 general supervision of the Trust's Board of Trustees, manages the Funds'
 portfolios. As compensation for the services rendered pursuant to the Agree-
 ments, the assumption of the expenses related thereto and administering the
 Funds' business affairs, including providing facilities, the respective ad-
 viser is entitled to a fee, computed daily and payable monthly, at an annual
 rate equal to .75%, .75%, .85%, .60% and .85% of the average daily net assets
 of the CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity, CORE
 Large Cap Value and CORE International Equity Funds, respectively.
   Each adviser had voluntarily agreed to limit certain "Other Expenses" for
 the CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity and CORE
 International Equity Funds (excluding management fees, distribution and
 service fees, transfer agent fees for CORE U.S. Equity Fund, taxes, interest,
 brokerage, litigation, Service share fees, indemnification costs and extraor-
 dinary expenses) through August 31, 1998, to the extent such expenses exceed,
 on an annual basis, .06%, .05%, .20% and .25% of the average daily net assets
 of the funds, respectively. Effective September 1, 1998 (December 31, 1998
 for CORE Large Cap Value), the expense limitation for the CORE U.S. Equity,
 CORE Large Cap Growth, CORE Small Cap Equity, CORE Large Cap Value and CORE
 International Funds was modified to .00%, .00%, .04%, .00% and .12% (exclud-
 ing management fees, distribution and service fees, transfer agent fees, tax-
 es, interest, brokerage, litigation, Service share fees, indemnification
 costs and other extraordinary expense).
   Goldman Sachs serves as the Distributor of shares of the Funds pursuant to
 a Distribution Agreement. Goldman Sachs may receive a portion of the Class A
 sales load and Class B and Class C contingent deferred sales charge and has
 advised the Funds that it retained approximately $517,000, $361,000,
 $121,000, $1,000 and $94,000 during the year ended January 31, 1999 for the
 CORE U.S. Equity, CORE Large Cap Growth, CORE Small Cap Equity, CORE Large
 Cap Value and CORE International Equity Funds, respectively.
   Prior to September 1, 1998, the Trust, on behalf of each Fund (except for
 CORE Large Cap Value which had not commenced operations), had adopted Distri-
 bution Plans (the "Distribution Plans") pursuant to Rule 12b-1. Under the
 Distribution Plans, Goldman Sachs was entitled to receive a quarterly fee
 from each Fund for distribution services equal, on an annual basis, to .25%,
 .75% and .75% of the Funds' average daily net assets attributable to Class A,
 Class B and Class C shares, respectively.
   Prior to September 1, 1998, the Trust, on behalf of each Fund (except for
 CORE Large Cap Value which had not commenced operations), had also adopted
 Authorized Dealer Service Plans (the "Dealer Service Plans") pursuant to
 which Goldman Sachs and Authorized Dealers were compensated for providing
 personal and account maintenance services. Each Fund paid a fee under the
 Dealer Service Plan equal, on an annual basis, up to .25% of its average
 daily net assets attributable to Class A, Class B and Class C shares.

   Effective September 1, 1998, the Distribution Plans and Dealer Service
 Plans were combined into a Distribution and Service Plan. Under the Distribu-
 tion and Service Plan, Goldman Sachs and/or Authorized Dealers are entitled
 to a monthly fee from each Fund for distribution and shareholder maintenance
 services equal, on an annual basis, to .25% (.50% on CORE International Equi-
 ty), 1.00%, and 1.00% of each of the Fund's average daily net assets attrib-
 utable to Class A, Class B and Class C shares, respectively.
   Goldman Sachs also serves as the Transfer Agent of the Funds for a fee. Ef-
 fective September 1, 1998, the fees charged for such transfer agency services
 are calculated daily and payable monthly at an annual rate as follows: .19%
 of the average daily net assets for Class A, Class B and Class C shares and
 .04% of the average daily net assets for Institutional and Service shares.
   The Trust, on behalf of each Fund, has adopted a Service Plan. This plan
 allows for Service shares to compensate service organizations for providing
 varying levels of account administration and shareholder liaison services to
 their customers who are beneficial owners of such shares. The Service Plan
 provides for compensation to the service organizations in an amount up to
 .50% (on a annualized basis), of the average daily net asset value of the
 Service shares.
 
 For the year ended January 31, 1999, Goldman Sachs, GSAM, GSFM and the Dis-
 tributor have voluntarily agreed to waive certain fees and reimburse other
 expenses as follows (in thousands):

   For the year ended January 31, 1999, Goldman Sachs earned approximately
 $284,000, $82,000, $62,000 and $130 brokerage commissions from portfolio
 transactions executed on behalf of the CORE U.S. Equity, CORE Large Cap
 Growth, CORE Small Cap Equity and CORE Large Cap Value, respectively.
 
 5. REPURCHASE AGREEMENTS
 
 During the term of a repurchase agreement, the value of the underlying secu-
 rities, 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 each Fund's custodian.
 
 6. JOINT REPURCHASE AGREEMENT ACCOUNT
 
 The Funds, together with other registered investment companies having manage-
 ment agreements with GSAM and GSFM or their affiliates, transfer uninvested
 cash into joint accounts, the daily aggregate balance of which is invested in
 one or more repurchase agreements.
   At January 31, 1999, the CORE U.S. Equity, CORE Large Cap Growth and CORE
 Small Cap Equity Funds had undivided interests in the repurchase agreements
 in the joint account which equaled $29,300,000, $21,100,000 and $3,500,000,
 respectively, in principal amount. At January 31, 1999, the following repur-
 chase agreements held in this joint account were fully collateralized by fed-
 eral agency obligations:

 7. LINE OF CREDIT FACILITY
 
 The Funds (except for CORE Large Cap Value Fund) participate in a
 $250,000,000 uncommitted, unsecured revolving line of credit facility. In ad-
 dition, the Funds (except for CORE Large Cap Value Fund) participate in a
 $50,000,000 committed, unsecured revolving line of credit facility. Both fa-
 cilities are to be used solely for temporary or emergency purposes. Under the
 most restrictive arrangement, the Funds 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. The committed facility
 also requires a fee to be paid based on the amount of the commitment which
 has not been utilized. During the year ended January 31, 1999, the Funds did
 not have any borrowings under these facilities.
 
 8. OTHER MATTERS AND CERTAIN RECLASSIFICATIONS
 
 As of January 31, 1999, Goldman, Sachs & Co. Profit Sharing Master Trust was
 the beneficial owner of approximately 13.9% of the outstanding shares of the
 CORE U.S. Equity Fund. In addition, the following Goldman Sachs Asset Alloca-
 tion Portfolios were beneficial owners of the Funds (as a percentage of out-
 standing shares):

 In accordance with Statement of Position 93-2, the CORE U.S. Equity Fund re-
 classified $33,945 from accumulated net realized gain on investment, futures
 and foreign currency transactions to paid-in capital, and $374,744 from accu-
 mulated net realized gain on investment, futures and foreign currency trans-
 actions to accumulated distributions in excess of net investment income. CORE
 Large Cap Growth Fund reclassified $510 from accumulated distributions in ex-
 cess of net investment income to accumulated net realized loss on investment,
 futures and foreign currency transactions, and $271 from paid-in capital to
 accumulated distributions in excess of net investment income. CORE Small Cap
 Equity Fund reclassified $400 from accumulated distributions in excess of net
 investment income to paid-in capital, $31 from accumulated distributions in
 excess of net investment income to accumulated net realized loss on invest-
 ment, futures and foreign currency transactions, and $1,374 from accumulated
 net realized loss on investment, futures and foreign currency transactions to
 paid-in capital. CORE International Equity Fund reclassified $489,679 from
 accumulated distributions in excess of net investment income to accumulated
 net realized loss on investment, futures and foreign currency transactions,
 and $400 from accumulated distributions in excess of net investment income to
 paid-in capital. These reclassifications have no impact on the net asset
 value of each Fund and are designed to present each Fund's capital accounts
 on a tax basis.
   On January 1, 1999, the European Monetary Union "EMU" introduced a new sin-
 gle currency, the euro, which will replace the national currencies of the
 participating member countries. Until 2002, the national currencies will con-
 tinue to exist, but exchange rates will be tied to the euro. The introduction
 of the euro is likely to affect all stages of the investment process, includ-
 ing trading, foreign exchange and accounting. Because this change to a single
 currency is new, the introduction of the euro may result in market volatility
 and may affect the business or financial conditions of European issuers or of
 a Portfolio investing in European issuers. In addition, while the conversion
 will eliminate currency risk among participating nations, currency risk be-
 tween the euro and the U.S. dollar remains a factor.

GOLDMAN SACHS TRUST - CORE EQUITY FUNDS
Report of Independent Public Accountants
 To the Shareholders and Board of Trustees of Goldman Sachs Trust - CORE Eq-
 uity Funds
 
 We have audited the accompanying statements of assets and liabilities of
 Goldman Sachs CORE U.S. Equity Fund, CORE Large Cap Growth Fund, CORE Small
 Cap Equity Fund, CORE Large Cap Value Fund and CORE International Equity
 Fund, portfolios of Goldman Sachs Trust--Equity Funds (a Delaware Business
 Trust), including the statements of investments, as of January 31, 1999, and
 the related statements of operations, the statements of changes in net assets
 and the financial highlights for the periods presented. These financial
 statements and the financial highlights are the responsibility of the Funds'
 management. Our responsibility is to express an opinion on these financial
 statements and the financial highlights based on our audits.
 
 We conducted our audits in accordance with generally accepted auditing stan-
 dards. Those standards require that we plan and perform the audit to obtain
 reasonable assurance about whether the financial statements and the financial
 highlights are free of material misstatement. An audit includes examining, on
 a test basis, evidence supporting the amounts and disclosures in the finan-
 cial statements. Our procedures included confirmation of securities owned as
 of January 31, 1999 by correspondence with the custodian and brokers. An au-
 dit also includes assessing the accounting principles used and significant
 estimates made by management, as well as evaluating the overall financial
 statement presentation. We believe that our audits provide a reasonable basis
 for our opinion.
 
 In our opinion, the financial statements and the financial highlights re-
 ferred to above present fairly, in all material respects, the financial posi-
 tion of Goldman Sachs CORE U.S. Equity Fund, CORE Large Cap Growth Fund, CORE
 Small Cap Equity Fund, CORE Large Cap Value Fund and CORE International Eq-
 uity Fund as of January 31, 1999, the results of their operations, the
 changes in their net assets and the financial highlights for the periods pre-
 sented, in conformity with generally accepted accounting principles.

CORE International Equity Fund's foreign investments and active management
techniques entail risks in addition to those customarily associated with
investing in dollar-denominated securities of U.S issuers. Compared with
domestic securities markets, foreign markets may be less liquid, more volatile
and less subject to government regulation, and may make available less public
information about issuers. The Funds may incur losses because of changes in
securities prices expressed in local currencies, movements in exchange rates or
both.

The stocks of smaller companies are often associated with higher risks,
including greater volatility, than stocks of larger companies.
