GOLDMAN SACHS TAXABLE INVESTMENT GRADE FUNDS

MARKET OVERVIEW


Dear Shareholder,

Investors' renewed interest in fixed income securities during the review period
was further fueled by a worldwide flight to quality in the wake of increased
levels of global market turmoil.

- --------------------------------------------------------------------------------
Mutual funds, annuities, and other investment products:

o     are not FDIC insured;

o     are not deposits or obligations of, or guaranteed by, any financial
      institution;

o     are subject to investment risks, including possible loss of the principal
      amount invested.
- --------------------------------------------------------------------------------

o     The Dollar Bloc -- For most of the review period, markets vacillated in
      response to investor optimism that the Asian ordeal was well in hand and
      investor fears that global market turmoil was threatening. The result was
      a 12-month period punctuated by market sell-offs and rallies. At period
      end, this touch-and-go global anxiety culminated in a powerful Treasury
      rally. The catalyst for the rally included investors' wholesale preference
      for Treasuries -- exacerbated by the ruble devaluation and Russia's de
      facto default -- and technical imbalances (forced liquidations by highly
      leveraged players combined with seasonal supply pressures). 

            Elsewhere in the dollar bloc, Canada, Australia and New Zealand
      generated mixed performance during the period under review. All three
      countries, however, ended the period on a positive note. Monetary
      conditions eased in both Canada and New Zealand, and the Bank of Canada
      cut rates. Likewise, Australian bonds performed well as the market started
      to discount an expected near-term easing by the Reserve Bank.

o     Europe -- Early in the period, Europe's bond markets rallied following an
      announcement by German officials that European Monetary Union (EMU)
      short-term interest rates would converge at the lower level of the core
      markets. The rallies continued into the new year, reinforced in part by
      "softer" retail sales data and lower than expected gross domestic product
      data. The onset of economic and political turmoil in Russia further helped
      European bond market performance. However, by period end, muted
      expectations of rate cuts in core European countries, combined with a
      changing political landscape in Germany, helped to limit the extent of
      Europe's bond rally.

o     Japan -- Continued troubles within the banking sector were a significant
      factor behind Japan's poor bond market performance early in the period.
      After a brief journey into positive territory in December, the market
      would continue its poor showing in the wake of the resignation of the
      Minister of Finance and amid assumptions that measures of fiscal stimulus
      were in the offing. When the long-awaited stimulus package was finally
      released, significant doubt remained as to whether it could lead to
      Japan's long-term recovery. Throughout the remainder of the period, this
      poorly received rescue package, combined with extremely weak gross
      domestic product, consumer spending and capital expenditure data, helped
      drive Japanese bond yields to record low levels.

o     Outlook -- Environment for Bonds Is Positive -- We believe the current
      positive global environment for bonds will continue for some time. We
      continue to favor Europe, and in particular the UK, where inflationary
      pressures are very low or in decline. In Japan, if global bond yields
      continue to decline, we expect that Japanese bonds will continue to
      underperform. 

            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      /s/ Sharmin Mossavar-Rahmani

PERFORMANCE OVERVIEW

Adjustable Rate Government Fund

Dear Shareholder,

We are pleased to report on the performance of the Goldman Sachs Adjustable Rate
Government Fund for the 12-month period ended October 31, 1998.

Performance Review

Over the 12-month period ended October 31, 1998, the Fund underperformed its
benchmarks, the six-month U.S. Treasury bill and the one-year U.S. Treasury
bill, which returned 5.72% and 6.32%, respectively. The Fund's underperformance
during the first half of the year was driven by weakening fundamentals; that is,
declining interest rates and a flattening yield curve. Underperformance during
the latter six months was driven by investors' preference for the safety and
liquidity of Treasuries.

Investment Objective

The Fund seeks a high level of current income consistent with low volatility of
principal, primarily through investments in adjustable rate mortgage securities
that are issued by the U.S. government, its agencies, instrumentalities or
sponsored enterprises.

Portfolio Composition

Our strategy is to focus on securities that we believe will perform well
relative to the overall market, regardless of the direction of interest rates.
Throughout the period, we managed the Fund's duration (0.75 years as of October
31, 1998) within a tight range of that of a nine-month U.S. Treasury security,
and employed Goldman, Sachs & Co.'s extensive research capabilities to identify
attractively valued securities offering incremental yield relative to
Treasuries.

Portfolio Highlights

o     Adjustable Rate Mortgages (ARMs) (84.2% on October 31, 1997 to 62.3% on
      October 31, 1998) -- The Fund's allocation to ARMs declined during the
      period as cash inflows were invested in alternative sectors with higher
      expected rates of return (for example, pass-throughs and CMOs).

o     Collateralized Mortgage Obligations (CMOs) (5.4% on October 31, 1997 to
      12.2% on October 31, 1998) -- Early in the period, we modestly increased
      the Fund's position in CMOs as we identified securities that possessed
      attractive yields and good cash flow stability. We maintained this
      position throughout the remaining months of the period under review.

                                   -----------

We adjust the term structure of our portfolios based on our expectations of the
relationship between short- and long-term interest rates, while keeping each
fund's duration close to its benchmark.


o     Fixed Rate Pass-Throughs (1.0% on October 31, 1997 to 11.5% on October 31,
      1998) -- The dramatic cheapening of mortgage pass-through securities
      (beyond that warranted by the fundamental environment) led us to
      substantially increase our allocation to the sector in the latter months
      of the period.

o     Cash (2.3% on October 31, 1997 to 8.6% on October 31, 1998) -- The Fund's
      cash position increased as we waited for opportunities to invest in
      attractively priced instruments.

Portfolio Outlook

Our outlook for the ARM sector has become cautiously optimistic as both
fundamental and technical influences have turned more positive. From a
fundamental standpoint, long-term interest rates have risen and the yield curve
has steepened. As a result, ARM-to-fixed rate refinancing incentives are now
less compelling. From a technical standpoint, the overall tone of the market has
firmed as well; hedge fund selling has abated, while supply pressures from new
mortgage origination activity have been concentrated primarily in fixed rate
versus adjustable rate collateral.

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

Short Duration Government Fund

Dear Shareholder,

We are pleased to report on the performance of the Goldman Sachs Short Duration
Government Fund for the 12-month period ended October 31, 1998.

Performance Review

Over the 12-month period ended October 31, 1998, the Fund underperformed the
7.65% return of its benchmark, the two-year U.S. Treasury note, as
mortgage-backed security spreads widened -- first, in response to falling
interest rates (and accompanying prepayment concerns) and later, in response to
global financial anxiety.

Investment Objective

The Fund seeks a high level of current income and, secondarily, in seeking
current income, it may also consider the potential for capital appreciation,
primarily through securities that are issued or guaranteed by the U.S.
government, its agencies, instrumentalities or sponsored enterprises.

Portfolio Composition

We maintained our strategy of focusing on securities that we believe will
perform well relative to the overall market, regardless of the direction of
interest rates. Our investment strategy is to closely manage the Fund's duration
(2.2 years as of October 31, 1998) within a tight range of that of its
benchmark, and to employ Goldman, Sachs & Co.'s extensive research capabilities
to identify attractively valued securities within the mortgage and agency
sectors.

Portfolio Highlights

o     Collateralized Mortgage Obligations (CMOs) (57.2% on October 31, 1997 to
      39.8% on October 31, 1998) -- The Fund's allocation to CMOs declined over
      the period as cash inflows were invested in alternative sectors -- for
      example, pass-throughs and agency debentures -- with more enhanced return
      opportunities.

o     Fixed Rate Pass-Throughs (5.6% on October 31, 1997 to 17.6% on October 31,
      1998) -- The Fund's position in fixed rate pass-through securities
      increased significantly over the 12-month period. Although we were
      initially cautious on pass-throughs given their tight spreads and
      vulnerability to prepayment risk, we increased the Fund's exposure to the
      sector after spreads widened following the global flight to Treasuries.


                                                                               5

                                   -----------

We adjust the term structure of our portfolios based on our expectations of the
relationship between short- and long-term interest rates, while keeping each
fund's duration close to its benchmark.

o     Adjustable Rate Mortgage Securities (ARMs) (15.5% on October 31, 1997 to
      12.4% on October 31, 1998) -- The Fund's allocation to ARMs declined
      moderately during the period as cash inflows were invested in alternative
      sectors with higher expected rates of return (for example, pass-throughs
      and agency debentures).

o     U.S. Treasuries (16.3% on October 31, 1997 to 19.6% on October 31, 1998)
      and Cash Equivalents (1.4% on October 31, 1997 to 2.9% on October 31,
      1998) -- During the period, the Fund's positions in U.S. Treasuries and
      cash fluctuated in response to shifts in other sectors.

Portfolio Outlook

Within the pass-through market, the technical environment has become more
favorable, as wider spreads have attracted a variety of investors and originator
selling has diminished. Refinancing is also less of a concern, with interest
rates currently more than 40 basis points off their lows. As a result, we are
optimistic on the sector (particularly over longer investment horizons), as we
believe current spreads should more than compensate for short-term volatility.

CMO spreads have widened in concert with pass-through spreads over the past
several months. Relative value opportunities should improve, however, as spreads
stabilize and liquidity returns to the sector.

Our outlook for the ARM sector has become cautiously optimistic, as both
fundamental and technical influences have turned more positive. From a
fundamental standpoint, long-term interest rates have risen and the yield curve
has steepened; as a result, ARM-to-fixed rate refinancing incentives are now
less compelling. From a technical standpoint, the overall tone of the market has
firmed as well; hedge fund selling has abated, while supply pressures from new
mortgage origination activity have been concentrated primarily in fixed rate
versus adjustable rate collateral.

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

PERFORMANCE OVERVIEW

Government Income Fund

Dear Shareholder,

We are pleased to report on the performance of the Goldman Sachs Government
Income Fund for the 12-month period ended October 31, 1998.

Performance Review

Over the review period, the Fund generated positive performance. However, it
slightly underperformed the 9.72% return of its benchmark, the Lehman
Government/Mortgage Index, as mortgage-backed security spreads widened -- first,
in response to falling interest rates (and accompanying prepayment concerns) and
later, in response to global financial anxiety.

Investment Objective

The Fund seeks a high level of current income consistent with safety of
principal, primarily through investments that include mortgage-backed securities
issued or guaranteed by the U.S. government, its agencies, instrumentalities or
sponsored enterprises.

Portfolio Composition

During the period, we maintained our strategy of focusing on securities that we
believe will perform well relative to the overall market regardless of the
direction of interest rates. Our investment strategy is to closely manage the
Fund's duration (4.41 years as of October 31, 1998) within a tight range of its
benchmark (4.12 years), and seek excess returns over the benchmark through
sector weightings and specific security selection.

Portfolio Highlights

o     Mortgage-Backed Securities (MBS) (48.2% on October 31, 1997 to 58.1% on
      October 31, 1998) -- The Fund's position in mortgage-backed securities
      increased over the 12-month period, primarily due to an increase in the
      pass-through sector. Although we were initially cautious on mortgages
      given their tight spreads and vulnerability to prepayment risk, we
      increased the Fund's exposure to pass-throughs after the sector cheapened
      following the global flight to Treasuries.

o     U.S. Treasuries (22.7% on October 31, 1997 to 16.1% on October 31, 1998)
      and Cash Equivalents (0.3% on October 31, 1997 to 11.3% on October 31,
      1998) -- During the period, the Fund's position in U.S. Treasuries
      decreased as we added to the Fund's position in mortgage-backed
      securities. The Fund's cash position increased from prior year end.

                                   -----------

We adjust the term structure of our portfolios based on our expectations of the
relationship between short- and long-term interest rates, while keeping each
fund's duration close to its benchmark.

o     Asset-Backed Securities (ABS) (17.9% on October 31, 1997 to 15.8% on
      October 31, 1998) -- Early in the period, ABS performed well as investors
      demonstrated renewed interest in the sector. However, spreads widened in
      concert with other credit sectors during the months following the Russian
      ruble devaluation.

o     Insured Revenue Bonds (Municipal Bonds) (2.7% on October 31, 1997 to 1.8%
      on October 31, 1998) -- We maintained a small position in municipal bonds
      in order to take advantage of persistent cheapening in the municipal
      sector. We expect to "unwind" this trade when equilibrium is restored.

Portfolio Outlook

In the mortgage-backed security market, supply pressures have abated and
refinancing activity is now less of a concern than previously. As a result, we
believe current spreads, particularly within the pass-through sub-sector, should
more than compensate for short-term volatility. Additionally, relative value
opportunities should improve as spreads stabilize and liquidity returns to the
collateralized mortgage obligations market. Finally, although further spread
volatility is possible going into year-end, the strong fundamental backdrop and
improving technical situation bode well for ABS spreads over the next several
months.

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

Core Fixed Income Fund

Dear Shareholder,

We are pleased to report on the performance of the Goldman Sachs Core Fixed
Income Fund for the 12-month period ended October 31, 1998.

Performance Review

Over the 12-month period ended October 31, 1998, the Fund generated positive
performance. Nonetheless, it slightly underperformed the 9.34% total return of
its benchmark, the Lehman Brothers Aggregate Bond Index. The Fund's
underperformance relative to its benchmark is primarily attributable to a
widening in mortgage-backed spreads -- first in response to falling interest
rates (and accompanying prepayment concerns) and later, in response to global
financial anxiety.

Investment Objective

The Fund seeks total return consisting of capital appreciation and income that
exceeds that of the Lehman Brothers Aggregate Bond Index, primarily through
fixed income securities, including securities issued or guaranteed by the U.S.
government, its agencies, instrumentalities or sponsored enterprises, corporate
securities, mortgage-backed securities and asset-backed securities.

Portfolio Composition

Our general investment strategy de-emphasizes Treasuries in favor of higher
yielding fixed income alternatives with enhanced total return potential.
Therefore, during the period under review, we underweighted Treasury and agency
securities relative to the benchmark, and overweighted corporate, mortgage,
asset-backed and emerging market debt securities.

Portfolio Highlights

o     Mortgage-Backed Securities (MBS) (37.4% on October 31, 1997 to 39.2% on
      October 31, 1998) -- Throughout the period, we maintained an overweighted
      position in mortgage-backed securities -- including collateralized
      mortgage obligations (CMOs) -- versus the benchmark. However, within the
      overall sector, we were cautious on pass-through securities given their
      tight spreads and vulnerability to prepayment risk until the final months
      of the period, when we increased the Fund's exposure to the subsector
      after spreads widened in response to the global flight to Treasuries.

o     Corporates (28.8% on October 31, 1997 to 28.3% on October 31, 1998) --
      Strong cash inflows into the Fund, combined with the fact that several
      bonds were called in the first six months of the period, resulted in a
      mid-period decrease in this position to 21.2%. In the remaining months of
      the period, however, we gradually added corporate exposure, particularly
      within the industrial and financial subsectors.


                                                                              11

                                   -----------

We adjust the term structure of our portfolios based on our expectations of the
relationship between short- and long-term interest rates, while keeping each
fund's duration close to its benchmark.

o     Asset-Backed Securities (ABS) (13.9% on October 31, 1997 to 11.9% on
      October 31, 1998) -- Early in the period, ABS performed well as investors
      demonstrated renewed interest in the sector. However, spreads widened in
      concert with other credit sectors during the months following the Russian
      ruble devaluation.

o     U.S. Treasuries (15.7% on October 31, 1997 to 17.5% on October 31, 1998)
      and Cash Equivalents (7.9% on October 31, 1998) -- The Fund's positions in
      U.S. Treasuries and cash equivalents fluctuated in response to increases
      in the Fund's exposure to both the mortgage pass-through and corporate
      sectors.

o     Emerging Market Debt (EMD) (5.0% on October 31, 1997 to 1.4% on October
      31, 1998) -- During the period under review, we reduced the Fund's
      position in emerging market debt. The reduction reflected our ongoing
      concern regarding the global economic outlook and our anticipation of
      continued spread volatility. The remaining exposure is concentrated in
      Latin America.

Portfolio Outlook

In the mortgage-backed security market, supply pressures have abated and
refinancing activity is now less of a concern. As a result, we believe current
spreads, particularly within the pass-through subsector, should more than
compensate for short-term volatility. Additionally, relative value opportunities
are likely to improve as spreads stabilize and liquidity returns to the CMO
market. Within the corporate sector, we intend to continue to look for
opportunities to add exposure in order to achieve a neutral position (on a
dollar-duration basis) relative to the corporate sector of the benchmark.
Regarding the ABS sector, although further spread volatility is possible going
into year-end, the strong fundamental backdrop and improving technical situation
should bode well for spreads over the next several months.

Finally, the outlook for EMD has improved recently, as both the U.S. Federal
Reserve and the Brazilian authorities have acted decisively to avoid a deepening
of the global financial crisis. The Fed's surprise easing, coupled with an
announced fiscal adjustment and impending IMF support package for Brazil, has
allayed fears of a global credit crunch and has led to tighter spreads in the
sector. Going forward, we may look to opportunistically add to countries with
low financing requirements.

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

PERFORMANCE OVERVIEW

Global Income Fund

Dear Shareholder,

We are pleased to report on the performance of the Goldman Sachs Global Income
Fund for the 12-month period ended October 31, 1998.

Performance Review

Over the 12-month period covered by this report, the Fund generated strong
performance. Nonetheless, it slightly underperformed the 12.70% total return of
its benchmark, the JP Morgan Global Government Bond Index (hedged into U.S.
dollars). Over the same period, the Fund outperformed the 4.28% return of its
peers within the Lipper Global Income Funds category, ranking the Fund's Class
A, B, C, Institutional and Service shares 12, 15, 16, 8 and 11, respectively,
out of 148 funds. For the five-year period ended October 31, 1998, the Fund's
Class A shares ranked 3 out of 62 funds. Please note that Lipper rankings do not
take sales charges into account and that past performance is not a guarantee of
future results. 

      A key factor behind the Fund's slight underperformance relative to its
benchmark was a short yen position, which was held in line with our ongoing view
that the Japanese economy is weak. Because of this position, however, the Fund
did not benefit from a brief rally in Japanese bonds that occurred in October.
Also, the Fund's overweight position in New Zealand bonds during the fourth
quarter of 1997 and the first quarter of 1998 further proved detrimental to
performance.

Investment Objective

The Fund seeks high total return, emphasizing current income and, to a lesser
extent, providing opportunities for capital appreciation primarily through
investments in fixed income securities of U.S. and foreign issuers and foreign
currencies.

Portfolio Positioning

The Fund maintained a neutral position versus the benchmark in Europe at the
beginning of the period, a position that was increased to an overweighting by
period end. The shift occurred as falling inflation, moderate growth and low
levels of unemployment indicated positive future performance for European bonds.
In the U.S. and other dollar bloc countries, a neutral position early in the
period was gradually increased to an overweight position amid signs of a slowing
global economy. Finally, in Japan, we closed the period with an underweight
position consistent with our pessimism regarding the health of Japan's financial
markets.

Portfolio Highlights

o     Danish Government Bonds -- The flight to quality through the recent
      sell-off in perceived higher risk assets also affected the Danish
      government bond market, and we used this as an opportunity to increase our
      positions. We expect Denmark to join the euro within the next three years.
      Moreover, the Danish Central Bank remains committed to keeping the krone
      closely pegged with the deutschemark/euro.

                                   -----------

We adjust the term structure of our portfolios based on our expectations of the
relationship between short- and long-term interest rates, while keeping each
fund's duration close to its benchmark.

o     UK Bonds -- After the extreme weakness in the export and manufacturing
      sectors, we have finally begun to see weakness in the consumer sector; for
      example, consumer confidence and retail sales have both markedly declined
      recently. While the Bank of England has already eased rates, we expect 75
      to 100 basis points of further rate cuts through the first half of 1999,
      as the consumer sector continues to deteriorate. This presents a favorable
      scenario for UK bonds.

o     Australian Bonds -- During the period, we held an overweight position in
      Australian bonds since, at one stage, the market was discounting a rate
      hike as the currency weakened. We viewed this as a temporary phenomenon
      prompted by the general weakness in Asian economies, and did not believe
      there was sufficient evidence to justify a rate hike. Hence, we purchased
      Australian bonds at spreads close to 100 basis points to
      equivalent-maturity U.S. bonds. The reduction of risk premia toward the
      end of the reporting period also translated into a stronger Australian
      dollar and an unwinding of rate hike expectations. This brought the
      Australian/U.S. spreads in by over 70 basis points, where we took profits.

      Portfolio Outlook

      Despite the recent stabilization in emerging markets, the U.S. equity
      market and credit conditions, we feel significant risks remain to the
      global and the U.S. domestic economy. The global outlook remains hinged on
      the success of policy measures in Japan to revive the economy and reform
      the banking sector, and on the success of the IMF package to Brazil. In
      both cases, we feel significant risks remain. The domestic economy of the
      U.S. is also vulnerable to any further deterioration in global growth, and
      there are already signs that the economy is slowing. We expect this to
      continue into 1999. Although we currently do not expect a full recession
      in the U.S. in 1999, we expect growth to slow enough to prompt the Federal
      Reserve into easing further, and we expect the bond market to perform
      strongly in this environment.

o     Euro 11 Markets -- In the Euro-11 markets, we expect the bond market to
      continue to strengthen. The inflation outlook for Europe remains very
      benign and we expect this to be reinforced by the introduction of EMU and
      the transfer of monetary policy to the new European Central Bank. The
      growth outlook for Europe is finely balanced and recent data is pointing
      to a slowing in the recovery. We expect European growth to be slowed
      further by the deteriorating international situation and there is a
      growing expectation that the next move in European rates will be a
      decline. This environment should be favorable for European bonds.

o     Non-Euro 11 Markets -- We expect non-Euro-11 markets to perform well in
      the medium-term. We expect the UK economy to slow sharply in 1999,
      prompting further cuts in interest rates. There is also an increasing
      market expectation that the UK will enter EMU within the next five years
      and we expect the UK bond market to converge further with core European
      markets. The Danish and Swedish markets are also likely to perform well as
      public sentiment in those countries shifts in favor of joining EMU.

o     Japan -- Our outlook for the Japanese bond market is negative. We expect
      the Japanese government to implement further economic and bank reform
      measures; the effects of these measures and the increase in bond supply is
      likely to be negative for the bond market.

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

GOLDMAN SACHS TAXABLE INVESTMENT GRADE FUNDS

By putting securities with different correlations to work in your portfolio, you
can expand your investment opportunities while potentially spreading your risk.

Fixed Income Funds --
An Effective Portfolio Diversifier

Recent global market events -- and resulting price volatility in the stock
market -- have encouraged many investors to seek more stability in their
portfolio through greater diversification. In many cases, investors have
increased their allocation to fixed income securities. What some individuals may
have overlooked is the extent to which they can diversify within the fixed
income arena. Different types of fixed income securities possess varying levels
of market correlation to each other, and therefore should be able to provide an
added measure of protection against market risk.

Differing Correlations May Help Reduce Exposure to Risk

Correlation simply defines how two investments move together. If you own two
highly correlated investments, their returns will tend to move in tandem. If you
own two loosely correlated assets, their returns will tend to move in opposite
directions.

The table below shows the different correlations between fixed income
securities. A high correlation of 0.99, such as that between cash and Treasury
bills, means these two securities tend to react similarly in a given market
environment. A low correlation such as 0.23, such as that between high yield
bonds and intermediate government bonds, means these two securities have a low
correlation -- a difference that could provide an important level of
diversification in a portfolio.

 The following graph shows the value as of October 31, 1998, of a $10,000 in-
 vestment made in Institutional shares on August 1, 1991. For comparative pur-
 poses, the performance of the Fund's benchmarks (the Lehman Brothers Mutual
 Fund Short (1-2) U.S. Government Index ("Lehman 1-2 Index") and the six-month
 and one-year U.S. Treasury Bills ("Six-Month T-Bill/One-Year T-Bill")) are
 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.
 Performance of Class A, Administration and Service shares will vary from In-
 stitutional shares due to differences in fees and loads.

GOLDMAN SACHS SHORT DURATION GOVERNMENT FUND
 
Performance Summary
October 31, 1998
 
 The following graph shows the value as of October 31, 1998, of a $10,000 in-
 vestment made in Institutional shares on September 1, 1988. For comparative
 purposes, the performance of the Fund's benchmarks (the U.S. 2-Year Treasury
 Bill ("Two-Year T-Bill") and the Lehman Brothers Mutual Fund Short (1-3) U.S.
 Government Index ("Lehman Short (1-3) Gov't Index")) are 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 A, Class B, Class C, Administration and Service shares will vary
 from Institutional shares due to differences in fees and loads.

Performance Summary
October 31, 1998
 
 The following graph shows the value as of October 31, 1998, of a $10,000 in-
 vestment made (with the maximum sales charge of 4.5%) in Class A shares on
 March 1, 1993. For comparative purposes, the performance of the Fund's bench-
 marks (the Lehman Brothers Mutual Fund Government/Mortgage Index ("Lehman
 Gov't/MBS Index") and the Lehman Brothers Mutual Fund General U.S. Government
 Index ("Lehman U.S. Gov't Index")) are shown. This performance data repre-
 sents past performance and should not be considered indicative of future per-
 formance 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.

 (a) TBA (To Be Assigned) securities are purchased on a forward commitment
     basis with an approximate (generally + /--2.5%) principal amount and no
     definite maturity date. The actual principal amount and maturity date
     will be determined upon settlement when the specific mortgage pools are
     assigned.
 (b) Represents security with notional or nominal principal amount. The actual
     effective yield of this security is different than the stated coupon due
     to the amortization of related premiums.
 (c) Variable rate security. Coupon rate disclosed is that which is in effect
     at October 31, 1998.
 (d) The interest rate disclosed for these securities represents effective
     yield to maturity.
 (e) Security is exempt from registration under rule 144A of the Securities
     Act of 1933. Such securities may be resold, normally to qualified
     institutional buyers in transactions exempt from registration. Total
     market value of the Rule 144A securities amounted to $2,055,700 as of
     October 31, 1998.
 (f) Portions of these securities are being segregated for open TBA purchases,
     forward sale contract, open futures contracts and futures margin
     requirements.
 (g) The amount stated also represents aggregate cost for federal income tax
     purposes.
 (h) Each Euro Dollar Contract represents $1,000,000 in notional par value.
     Each 5-Year and 10-Year U.S. Treasury Note contract represents $100,000
     in notional par value. Each 2-Year U.S. Treasury Note contract represents
     $200,000 in notional par value. The total notional amount and market
     value at risk are $95,400,000 and 38,596,038, respectively. The
     determination of notional amounts as presented here are indicative only
     of volume of activity and not a measure of market risk.
The percentage shown for each investment category reflects the value of
investments in that category as a percentage of total net assets.

Performance Summary
October 31, 1998
 
 The following graph shows the value as of October 31, 1998, of a $10,000 in-
 vestment made in Institutional shares on January 5, 1994 (commencement of
 operations). For comparative purposes, the performance of the Fund's bench-
 mark (the Lehman Brothers Aggregate Bond Index ("Lehman Aggregate 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.
 Performance of Class A, Class B, Class C, Administration and Service shares
 will vary from Institutional shares due to differences in fees and loads.

 benchmark (the J.P. Morgan Global Government Bond Index hedged to U.S. Dol-
 lars (the "J.P. Morgan GGB Index - $ Hedged")) 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 re-
 deemed, 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.

GOLDMAN SACHS TAXABLE INVESTMENT GRADE FUNDS
 
Notes to Financial Statements
October 31, 1998
 
 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 Goldman Sachs Adjustable Rate
 Government Fund (Adjustable Rate Government), Goldman Sachs Short Duration
 Government Fund (Short Duration Government), Goldman Sachs Government Income
 Fund (Government Income), Goldman Sachs Core Fixed Income Fund (Core Fixed
 Income) and Goldman Sachs Global Income Fund (Global Income), collectively,
 "the Funds" or individually a "Fund." Adjustable Rate Government, Short Dura-
 tion Government, Government Income, and Core Fixed Income are diversified
 portfolios of the Trust whereas Global Income is a non-diversified portfolio.
 Adjustable Rate Government offers four classes of shares -- Class A, Institu-
 tional, Administration and Service. Government Income and Global Income offer
 five classes of shares -- Class A, Class B, Class C, Institutional and Serv-
 ice. Short Duration Government and Core Fixed Income offer six classes of
 shares -- Class A, Class B, Class C, Institutional, Administration and Serv-
 ice.
 
 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 es-
 timates and assumptions that may affect the reported amounts. Certain reclas-
 sifications have been made to the prior period's amounts to conform with the
 current period presentation. Such reclassifications have no effect on previ-
 ously reported net asset values of the Fund.
 
 A. INVESTMENT VALUATION -- Portfolio securities for which accurate market
 quotations are readily available are valued on the basis of quotations fur-
 nished by a pricing service or provided by dealers in such securities. Port-
 folio securities for which accurate market quotations are not readily
 available are valued based on yield equivalents, pricing matrices or other
 sources, under valuation procedures established by the Trust's Board of
 Trustees. Short-term debt obligations maturing in sixty days or less are val-
 ued at amortized cost.
 
 B. SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are
 recorded on trade date. Realized gains and losses on sales of portfolio secu-
 rities are calculated using the identified cost basis. Interest income is re-
 corded on the basis of interest accrued. Premiums on interest-only securities
 and on collateralized mortgage obligations with nominal principal amounts are
 amortized, on an effective yield basis, over the expected lives of the re-
 spective securities.
   Certain mortgage security paydown gains and losses are taxable as ordinary
 income. Such paydown gains and losses increase or decrease taxable ordinary
 income available for distribution and are classified as interest income in
 the accompanying Statements of Operations. Original issue discounts ("OID")
 on debt securities are amortized to interest income over the life of the se-
 curity with a corresponding increase in the cost basis of that security. OID
 amortization on mortgage backed REMIC securities is initially recorded based
 on estimates of principal paydowns using the most recent OID factors avail-
 able from the issuer. Recorded amortization amounts are adjusted when actual
 OID factors are received. Market discounts and market premiums on debt secu-
 rities, other than mortgage backed REMIC securities, are amortized to inter-
 est income over the life of the security with a corresponding adjustment in
 the cost basis of that security for Core Fixed Income. Global Income amor-
 tizes only market discounts on debt securities other than REMIC mortgage
 backed securities.

 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 of its investment company taxable
 and tax- exempt 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 a portfolio's 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, 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.
   Adjustable Rate Government and Short Duration Government, at their most re-
 cent tax year-ends of December 31, 1997, had approximately the following
 amounts of capital loss carryforward for U.S. federal tax purposes. These
 amounts are available to be carried forward to offset future capital gains to
 the extent permitted by applicable laws or regulations.

 D. EXPENSES -- Expenses incurred by the Trust that do not specifically relate
 to an individual Fund of the Trust are allocated to the Funds based on 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 and Administration shares bear all expenses and fees paid
 to service organizations for their services with respect to such shares. Ef-
 fective October 1, 1998, each class of shares of the Funds now separately
 bear their respective class-specific transfer agency fees.
 
 E. DEFERRED ORGANIZATION EXPENSES -- Organization-related costs are being am-
 ortized on a straight-line basis over a period of five years. The amortiza-
 tion costs of Adjustable Rate Government, Short Duration Government,
 Government Income and Global Income are fully amortized.
 
 F. 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; (ii) purchases and sales of foreign investments,
 income and expenses are converted into U.S. dollars based upon currency ex-
 change 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 and sale of investments; (ii) gains and losses be-
 tween trade date and settlement date on investment securities transactions
 and forward exchange contracts; and (iii) gains and losses from the differ-
 ence between amounts of interest recorded and the amounts actually received.
 
 G. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- Core Fixed Income and
 Global Income may enter into forward foreign currency exchange contracts for
 the purchase or sale of a specific foreign currency at a fixed price on a fu-
 ture date as a hedge or cross-hedge against either specific transactions or
 portfolio positions. Core Fixed Income and Global Income may also purchase
 and sell forward contracts to seek to increase total return. All commitments
 are "marked-to-market" daily at
 
                                                                              47

 the applicable translation rates and any resulting unrealized gains or losses
 are recorded in the Funds' financial statements. The Funds record realized
 gains or losses at the time a forward contract is offset by entry into a
 closing transaction or extinguished by delivery of the currency. Risks may
 arise upon entering into these contracts from the potential inability of
 counterparties to meet the terms of their contracts and from unanticipated
 movements in the value of a foreign currency relative to the U.S. dollar.
 
 H. FUTURES CONTRACTS -- The Funds may enter into futures transactions to
 hedge against changes in interest rates, securities prices, currency exchange
 rates (in the case of Core Fixed Income and Global Income) or to seek to in-
 crease 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 contracts ("variation margin") are paid or received by the Funds
 daily, dependent on the daily fluctuations in the value of the contracts, and
 are recorded for financial reporting purposes as unrealized gains or losses.
 When contracts are closed, the Funds realize a gain or loss which is reported
 in the Statements 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'
 hedging strategies and potentially result in a loss.
 
 I. 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.
 
 J. MORTGAGE DOLLAR ROLLS -- The Funds may enter into mortgage "dollar rolls"
 in which the Funds sell securities in the current month for delivery and si-
 multaneously contract with the same counterparty to repurchase similar (same
 type, coupon and maturity) but not identical securities on a specified future
 date. For financial reporting and tax reporting purposes, the Funds treat
 mortgage dollar rolls as two separate transactions; one involving the pur-
 chase of a security and a separate transaction involving a sale.

 3. AGREEMENTS
 
 Pursuant to the Investment Management Agreements (the "Agreements"), Goldman
 Sachs Funds Management, L.P. ("GSFM"), an affiliate of Goldman, Sachs & Co.
 ("Goldman Sachs"), serves as the investment adviser for Adjustable Rate Gov-
 ernment and Short Duration Government. Goldman Sachs Asset Management
 ("GSAM"), a separate operating division of Goldman Sachs, serves as the in-
 vestment adviser for Government Income and Core Fixed Income. Goldman Sachs
 Asset Management International ("GSAMI"), an affiliate of GSAM, serves as the
 investment adviser for Global Income. 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 pur-
 suant to the Agreements, the assumption of the expenses related thereto and
 administering the Funds' business affairs, including providing facilities,
 the adviser is entitled to a fee, computed daily and payable monthly at an
 annual rate equal to .40%, .50%, .65%, .40% and .90% of average daily net as-
 sets of Adjustable Rate Government, Short Duration Government, Government In-
 come, Core Fixed Income and Global Income, respectively.
   Each adviser has voluntarily agreed to limit "Other Expenses", with the ex-
 ception of Adjustable Rate Government, (excluding management fees, distribu-
 tion and service fees, taxes, interest, brokerage, litigation, Administrative
 and Service share fees, indemnification costs and other extraordinary ex-
 penses and with respect to Global Income, transfer agent fees) to the extent
 that such expenses exceeded .05%, .00%, .05% and .06% of the average daily
 net assets of Short Duration Government, Government Income, Core Fixed Income
 and Global Income, respectively. Effective September 1, 1998 for Global In-
 come and October 1, 1998 for Adjustable Rate Government, Short Duration Gov-
 ernment, Government Income and Core Fixed Income, these expense limitations
 were modified to .00%, .05%, .00%, .00% and .10% (excluding management fees,
 distribution and service fees, transfer agent fees, taxes, interest, broker-
 age, litigation, administration and service share fees, indemnification costs
 and extraordinary expenses), respectively.
   Goldman Sachs serves as Distributor of the 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 charges and has
 advised the Funds that it retained approximately $28,000, $157,000, $212,000,
 $82,000 and $133,000 for the year ended October 31, 1998 for Adjustable Rate
 Government, Short Duration Government, Government Income, Core Fixed Income
 and Global Income, respectively.
   The Trust, on behalf of each Fund, had adopted Distribution Plans (the
 "Distribution Plans") pursuant to Rule 12b-1. Under the Distribution Plans,
 Goldman Sachs was entitled to a quarterly fee from each Fund for distribution
 services equal, on an annual basis, to .25%, .75% and .75% of the average
 daily net assets attributable to Class A, Class B and Class C shares, respec-
 tively.
   The Trust, on behalf of each Fund, had adopted Authorized Dealer Service
 Plans (the "Dealer Service Plans") pursuant to which Goldman Sachs and Autho-
 rized Dealers were compensated for providing personal and account maintenance
 services. Each Fund paid a fee under the Dealer Service Plan equal, on an an-
 nual basis, up to .25% of its average daily net assets attributable to Class
 A, Class B and Class C shares.
   Effective September 1, 1998 for Global Income and October 1, 1998 for Ad-
 justable Rate Government, Short Duration Government, Government Income and
 Core Fixed Income, the Distribution Plans and Dealer Service Plans were com-
 bined into Distribution and Service plans. Under the Distribution and Service
 Plans, Goldman Sachs and/or Authorized Dealers are entitled to a monthly fee
 from each fund for distribution services and shareholder maintenance equal,
 on an annual basis, to .50%, 1.00% and 1.00% for Global Income and .25%,
 1.00% and 1.00% of each of the other funds' average daily net assets attrib-
 utable to Class A, Class B and Class C shares, respectively.
   Goldman Sachs also serves as Transfer Agent of the Funds for a fee. Effec-
 tive September 1, 1998 for Global Income and October 1, 1998 for Adjustable
 Rate Government, Short Duration Government, Government Income and Core Fixed
 Income, the fees charged for such transfer agency services are calculated
 daily and payable monthly at an annual rate as
 
                                                                              49

 follows: .19% of average daily net assets for Class A, Class B and Class C
 shares and .04% of average daily net assets for Institutional, Service and
 Administration Shares.
   The Trust, on behalf of the Funds, has adopted Service Plans. In addition,
 the Trust, on behalf of Adjustable Rate Government, Short Duration Government
 and Core Fixed Income, has adopted Administration Plans. These plans allow
 for Service shares and Administration shares, respectively, 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 and Administration Plans provide for compensation
 to the service organizations in an amount up to .50% and .25% (on an
 annualized basis), respectively, of the average daily net asset value of the
 respective shares.
   For the year ended October 31, 1998, the advisors and distributor have vol-
 untarily agreed to waive certain fees and reimburse other expenses as follows

Notes to Financial Statements
October 31, 1998
 
   The contractual amounts of forward foreign currency exchange contracts do
 not necessarily represent the amounts potentially subject to risk. The mea-
 surement of the risks associated with these instruments is meaningful only
 when all related and offsetting transactions are considered. At October 31,
 1998, Global Income had sufficient cash and/or securities to cover any com-
 mitments under these contracts.
   Global Income has recorded a "Receivable for forward foreign currency ex-
 change contracts" and "Payable for forward foreign currency exchange con-
 tracts" resulting from open and closed but not settled forward foreign
 currency exchange contracts of $1,802,980 and $4,943,283, respectively, in
 the accompanying Statement of Assets and Liabilities. Included in the Global
 Income "Receivable and Payable for forward foreign currency exchange con-
 tracts" are $588,209 and $1,344,045, respectively, related to forward con-
 tracts closed but not settled as of October 31, 1998.
   For the year ended October 31, 1998, Adjustable Rate Government, Short Du-
 ration Government, Government Income, Core Fixed Income and Global Income in-
 curred commission expenses of approximately $54,000, $26,000, $8,000, $9,000
 and $8,000, respectively, in connection with futures contracts entered into
 with Goldman Sachs. At October 31, 1998, Goldman Sachs was owed approximately
 $157,000, $131,000, $130,000 and $128,000 from Adjustable Rate Government,
 Short Duration Government, Government Income and Core Fixed Income, respec-
 tively, related to variation margin on futures contracts. Goldman Sachs owed
 approximately $30,000 to Global Income related to variation margin on futures
 contracts.
 
 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 the Funds' custodian.
 
 6. JOINT REPURCHASE AGREEMENT ACCOUNT
 
 The Funds, together with other registered investment companies having manage-
 ment agreements with GSFM, GSAMI and GSAM or their affiliates, transfer
 uninvested cash into joint accounts, the daily aggregate balance of which is
 invested in one or more repurchase agreements.
   At October 31, 1998, Adjustable Rate Government, Short Duration Government,
 Government Income and Core Fixed Income had undivided interests in the repur-
 chase agreements in the following joint account which equaled $43,700,000,
 $6,400,000, $14,600,000 and $22,300,000, respectively, in principal amount.
 At October 31, 1998, the following repurchase agreements held in this joint
 account were fully collateralized by U.S. Treasury and agency obligations.

 7. LINE OF CREDIT FACILITY
 
 The Funds participate in a $250,000,000 uncommitted, unsecured revolving line
 of credit facility. In addition, Global Income participates in a $50,000,000
 committed, unsecured revolving line of credit facility. Both facilities are
 to be used solely for temporary or emergency purposes. Under the most re-
 strictive 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. The committed facility also
 requires a fee to be paid by the Fund based on the amount of the commitment
 which has not been utilized. During the year ended October 31, 1998, the
 Funds did not have any borrowings under these facilities.
 
 8. OTHER MATTERS
 
 As of October 31, 1998, the Goldman, Sachs & Co. Profit Sharing Master Trust
 was the beneficial owner of approximately 20% and 15% of the outstanding
 shares of Short Duration Government and Global Income, respectively. In addi-
 tion, the Goldman Sachs Balanced Strategy Portfolio was the beneficial owner
 of approximately 14%, 3% and 1% of the outstanding shares of Short Duration
 Government, Global Income and High Yield, respectively. The Goldman Sachs
 Growth and Income Strategy Portfolio was the beneficial owner of approxi-
 mately 19%, 15% and 5% of the outstanding shares of Core Fixed Income, Global
 Income and High Yield, respectively. The Goldman Sachs Growth Strategy Port-
 folio was the beneficial owner of approximately 6%, 4% and 2% of Core Fixed
 Income, Global Income and High Yield, respectively.
 
 9. CERTAIN RECLASSIFICATIONS
 
 In accordance with Statement of Position 93-2, Adjustable Rate Government has
 reclassified $938,738 and $1,410,151 from paid-in capital to accumulated dis-
 tributions in excess of net investment income and accumulated net realized
 loss, respectively. Short Duration Government has reclassified $33,684 and
 $8,196 to paid-in capital and accumulated undistributed net investment in-
 come, respectively, from accumulated net realized loss. Government Income has
 reclassified $1,659 from paid-in capital to accumulated distributions in ex-
 cess of net investment income and an additional $164,196 and $15,707 from ac-
 cumulated net realized gain to accumulated distributions in excess of net
 investment income and paid-in capital, respectively. Core Fixed Income has
 reclassified $24,095 and $444,061 from paid-in capital and accumulated net
 realized gain, respectively, to accumulated distributions in excess of net
 investment income. In addition, Core Fixed Income has reclassified $2,294 and
 $19,060 from accumulated distributions in excess of net investment income to
 paid-in capital and accumulated net realized gain, respectively. Global In-
 come has reclassified $6,564,667 from accumulated undistributed net invest-
 ment income to accumulated net realized gain and an additional $30,213 and
 $726,330 from paid-in capital to accumulated undistributed net investment in-
 come and accumulated net realized gain, respectively.
 
 These reclassifications have no impact on the net asset value of the Funds
 and are designed to present the Fund's capital accounts on a tax basis.

GOLDMAN SACHS TRUST TAXABLE INVESTMENT GRADE FUNDS
 
Report of Independent Public Accountants
 
 To the Shareholders and Board of Trustees of Goldman Sachs Trust -- Taxable
 Investment Grade Fixed Income Funds:
 
 We have audited the accompanying statements of assets and liabilities of
 Goldman Sachs Adjustable Rate Government Fund, Short Duration Government
 Fund, Government Income Fund, Core Fixed Income Fund and Global Income Fund,
 five of the portfolios constituting Goldman Sachs Trust -- Fixed Income Funds
 (a Delaware Business Trust), including the statements of investments, as of
 October 31, 1998, and the related statements of operations and the statements
 of changes in net assets and the financial highlights for the periods pre-
 sented. These financial statements and the financial highlights are the re-
 sponsibility 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 October 31, 1998 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 Adjustable Rate Government Fund, Short Duration
 Government Fund, Government Income Fund, Core Fixed Income Fund and Global
 Income Fund as of October 31, 1998, the results of their operations and the
 changes in their net assets and the financial highlights for the periods pre-
 sented, in conformity with generally accepted accounting principles.

of measurement. The population correlation calculation is computed as the
covariance of the monthly return series divided by the product of their standard
deviations. Correlations based on monthly returns from 10/31/88 through 10/31/98
of the following: Cash - 1-month Certificate of Deposit (CD). Treasury Bill -

Long Term Government Bonds - Lehman Long Term Government Bond Index; Lehman
Government Bond Indices are made up of agency (all publicly issued debt of U.S.
Government agencies and quasi-federal corporations, and corporate debt
guaranteed by the U.S. Government) and treasury securities (all public
obligations of the U.S. Treasury, excluding flower bonds and foreign-targeted
issues). Corporate Bonds - the Lehman Aggregate Bond Index represents a
diversified portfolio of fixed income securities, including U.S. Treasuries,
investment-grade corporation bonds, and mortgage- and asset-backed securities.
Municipal Bonds - the Lehman Muni 10-Year Index, a broad-based total return
index that is comprised of investment grade, fixed rate, long-term maturities
(ranging from nine to 12 years) and are selected from issues larger than $50

Goldman Sachs High Yield Fund invests primarily in high yield, fixed income
securities rated below investment grade that are considered speculative and
generally involve greater price volatility and greater risk of loss of principal
and interest than investments in higher rated fixed income securities.

Goldman Sachs Global Income Fund's, Goldman Sachs High Yield Fund's and Goldman
Sachs Core Fixed Income 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 U.S.
securities markets, foreign markets may be less liquid, more volatile and less
subject to governmental 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.

Goldman Sachs Municipal Income Fund and Goldman Sachs Short Duration Tax-Free
Fund can invest up to 100% and 20%, respectively, in private activity bonds, the
interest from which is subject to the federal alternative minimum tax.
