Shareholder Letter
 Dear Shareholders,
 The following is a report on the performance of the Goldman Sachs Variable
 Insurance Trust Growth and Income Fund. This semiannual report covers the
 six-month period ended June 30, 1999.

                   Performance Review

                   For the six-month period ended June 30, 1999 the Fund gen-
                   erated a 10.43% cumulative total return. Over the same time
                   period, the Fund's benchmark, the Standard & Poor's 500 In-
                   dex (with dividends reinvested) (S&P 500 Index), generated
                   a cumulative total return of 12.38%.

                   The last six months have been a study in contrasts in the
                   U.S. equity market and for the Fund. During the first quar-
                   ter of 1999 the stock market rose, but the rally was ex-
                   tremely narrow--limited mostly to a few very large growth
                   companies and the technology sector. In contrast, the
                   Fund's strategy is to invest primarily in companies whose
                   share prices appear discounted relative to long-term value,
                   due to near-term uncertainty or pessimism in the market-
                   place. As a result of this value bias, the Fund
                   underperformed the S&P 500 Index during the quarter.

                   However, in April we saw a reversal of fortune, as invest-
                   ors abruptly shifted gears and took renewed interest in ec-
                   onomically sensitive and generally less expensive stocks.
                   This dramatic change continued throughout the second quar-
                   ter, and during that period the Fund outperformed its
                   benchmark.

                   The Fund's performance was enhanced by successful stock se-
                   lection. For example, our energy holdings significantly
                   outperformed the market and other stocks in the industry.
                   We built up a significant position in the energy sector
                   early in the year, due to our view that oil stocks re-
                   flected unsustainable low oil prices. As oil prices began
                   to rise in March, several of the Fund's oil-related stocks
                   contributed solid gains to the portfolio. Successful stock
                   selection in forest products, motor vehicles and drugs also
                   fueled performance in the first six months of the year. We
                   took advantage of strong performance to take profits from
                   Georgia Pacific Corp., which benefited from a rebound in
                   pricing outlook and forecasts of substantially higher earn-
                   ings in the near term. Among autos, our holding in
                   LucasVarity was acquired, thus boosting the stock past our
                   target price. As a result, we liquidated the position and
                   generated profits for the Fund. Finally, we benefited from
                   pharmaceutical holdings such as Bristol Myers Squibb, Eli
                   Lilly and Warner Lambert. Although we were underweight in
                   this group based on valuation, our holdings--among the
                   least expensive of the industry at the time of purchase--
                   substantially outperformed the market and contributed posi-
                   tively to performance.

                   Investment Objective

                   The Fund seeks long-term capital growth and growth of in-
                   come primarily through investments in equity securities of
                   companies selling at a discount to their long-term earning
                   and/or dividend-paying ability.

                                                                               1

                   * Opinions expressed in this report represent our present
                   opinions only. References to individual securities should
                   not be construed as commitments that such securities will
                   be retained in the Fund. From time to time, the Fund may
                   change the individual securities it holds, the number or
                   types of securities held and the markets in which it in-
                   vests. References to individual securities do not consti-
                   tute recommendations to the investor to buy, hold or sell
                   such securities. In addition, references to past perfor-
                   mance of the Fund do not indicate future returns, which are
                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   Outlook

                   We continue to improve the Fund's level of diversification
                   and liquidity in order to provide returns more consistent
                   with its peer group and the S&P 500 Index. Within this risk
                   management framework, we maintain a value orientation and
                   hope to continue to add value through stock selection and
                   fundamental research. We believe that our holdings, which
                   collectively sell at a discount to the S&P 500 Index, offer
                   both a margin of downside protection and significant upside
                   return potential over the business cycle.

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

                  GOLDMAN SACHS VARIABLE INSURANCE TRUST CORESM U.S. EQUITY FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust CORE U.S. Equity Fund. This semiannual report covers the six-
 month period ended June 30, 1999.

                   Performance Review

                   For the six-month period ended June 30, 1999 the Fund gen-
                   erated a 13.75% cumulative total return, outperforming the
                   12.38% cumulative total return of its benchmark, the Stan-
                   dard & Poor's 500 Index (with dividends reinvested).

                   The CORE strategy is a well-defined investment process that
                   has historically provided consistent, risk-managed perfor-
                   mance, with a reduced risk that returns will be very dif-
                   ferent from those of a specific benchmark over time.
                   Additionally, the diversification of our models typically
                   adds value, because when one theme doesn't work, others
                   usually do. For example, when momentum stocks underperform,
                   value stocks typically advance more than average.

                   The Fund's investment process and diversification of themes
                   were key benefits during the reporting period, as we expe-
                   rienced dramatic shifts in investor sentiment. During the
                   first quarter of the year the stock market's rally was ex-
                   tremely narrow, limited mostly to a few very large growth
                   companies and the technology sector. Early in the second
                   quarter, investors rotated assets into value-oriented,
                   smaller-cap and cyclical issues, but were back to prefer-
                   ring large-cap growth by the time the quarter ended. In the
                   first quarter, the momentum theme of our quantitative proc-
                   ess helped us to select winning stocks, although as the
                   market's preferences shifted, momentum had a difficult time
                   maintaining these results. Overall, during the first six
                   months of the year the Fund was able to outperform its
                   benchmark by 137 basis points.

                   Investment Objective

                   The Fund seeks long-term capital growth and dividend income
                   through a broadly diversified portfolio of large-cap and
                   blue chip equity securities representing all major sectors
                   of the U.S. economy.

                   The portfolio employs a disciplined approach that combines
                   fundamental investment research provided by Goldman, Sachs
                   & Co.'s Global Investment Research Department and consensus
                   opinions, with quantitative analysis generated by the Asset
                   Management Division's proprietary model. This quantitative
                   system evaluates each stock using many different criteria,
                   including valuation measures, growth expectations, earnings
                   momentum and risk profile. It also objectively analyzes the
                   impact of current economic conditions on different types of
                   stocks to determine where the emphasis should be placed.
                   While maintaining a profile close to that of the benchmark,
                   those stocks ranked highly by both the quantitative model
                   and the Goldman Sachs Global Investment Research Department
                   are selected for the portfolio.

                                                                               5

                   * Opinions expressed in this report represent our present
                   opinions only. References to individual securities should
                   not be construed as commitments that such securities will
                   be retained in the Fund. From time to time, the Fund may
                   change the individual securities it holds, the number or
                   types of securities held and the markets in which it in-
                   vests. References to individual securities do not consti-
                   tute recommendations to the investor to buy, hold or sell
                   such securities. In addition, references to past perfor-
                   mance of the Fund do not indicate future returns, which are
                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   Outlook

                   Despite a period of shifting investor preference and above
                   average return dispersion (the difference between the best-
                   and worst-performing stocks), the Fund's investment process
                   outperformed its benchmark for the reporting period. Going
                   forward, we continue to believe that 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 fa-
                   vored by research analysts. As such, we anticipate remain-
                   ing fully invested and believe that the value we add over
                   time will be due to stock selection, as opposed to sector
                   or size allocations.

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

GOLDMAN SACHS VARIABLE INSURANCE TRUST CORE LARGE CAP GROWTH FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust CORE Large Cap Growth Fund. This semiannual report covers the
 six-month period ended June 30, 1999.

                   Performance Review

                   For the six-month period ended June 30, 1999 the Fund gen-
                   erated a 12.50% cumulative total return, outperforming the
                   10.45% cumulative total return generated by its benchmark,
                   the Russell 1000 Growth Index.

                   The CORE strategy is a well-defined investment process that
                   has historically provided consistent, risk-managed perfor-
                   mance, with a reduced risk that returns will be very dif-
                   ferent from those of a specific benchmark over time.
                   Additionally, the diversification of our models typically
                   adds value, because when one theme doesn't work, others
                   usually do. For example, when growth stocks underperform,
                   our value component (i.e. seeking the most attractively
                   valued stocks within the growth universe) can lead to
                   strong results.

                   The Fund's investment process and diversification were key
                   benefits during the reporting period, as we experienced
                   dramatic shifts in investor sentiment. During the first
                   quarter of the year the stock market's rally was extremely
                   narrow, limited mostly to a few very large growth companies
                   and the technology sector. However, with the economy grow-
                   ing faster than anticipated and an economic recovery becom-
                   ing more evident outside the U.S., investors began focusing
                   on cyclical sectors of the market that tend to be more val-
                   ue-oriented.

                   Despite the change in preference, our quantitative process
                   helped us to select winning stocks with good momentum that
                   also appeared to be good values. As a result, the Fund was
                   able to outperform its benchmark by 205 basis points.

                   Investment Objective

                   The Fund seeks long-term capital growth, primarily through
                   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.

                   The portfolio employs a disciplined approach that combines
                   fundamental investment research provided by Goldman, Sachs
                   & Co.'s Global Investment Research Department and consensus
                   opinions, with quantitative analysis generated by the Asset
                   Management Division's proprietary model. This quantitative
                   system evaluates each stock using many different criteria,
                   including valuation measures, growth expectations, earnings
                   momentum and risk profile. It also objectively analyses the
                   impact of current economic conditions on different types of
                   stocks to determine where the emphasis should be placed.
                   The portfolio construction process evaluates stocks based
                   on their overall expected return and their contribution to
                   portfolio risk. The final portfolio is the one that we be-
                   lieve has the highest expected return for the targeted
                   amount of risk.

                   * Opinions expressed in this report represent our present
                   opinions only. References to individual securities should
                   not be construed as commitments that such securities will
                   be retained in the Fund. From time to time, the Fund may
                   change the individual securities it holds, the number or
                   types of securities held and the markets in which it in-
                   vests. References to individual securities do not consti-
                   tute recommendations to the investor to buy, hold or sell
                   such securities. In addition, references to past perfor-
                   mance of the Fund do not indicate future returns, which are
                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   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 do exposures to other risk factors (such
                   as dividend yield). Based on long-term results, our quanti-
                   tative process prefers low P/E and low price/book stocks
                   with good momentum characteristics that exhibit stability
                   in stock price and earnings, and that are favored by re-
                   search analysts. As such, we maintain an exposure to secu-
                   rities that display these factors.

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

                GOLDMAN SACHS VARIABLE INSURANCE TRUST CORE LARGE CAP VALUE FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust CORE Large Cap Value Fund. This semiannual report covers the
 period from April 1, 1999, when the Fund began operations, through June 30,
 1999.

                   Performance Review

                   From April 1, 1999 through June 30, 1999, the Fund gener-
                   ated a 10.90% cumulative total return. This compares to an
                   11.27% cumulative total return of its benchmark, the Rus-
                   sell 1000 Value Index.

                   The CORE strategy is a well-defined investment process that
                   has historically provided consistent, risk-managed perfor-
                   mance, with a reduced risk that returns will be very dif-
                   ferent from those of a specific benchmark over time.
                   Additionally, the diversification of our models typically
                   adds value, because when one theme doesn't work, others
                   usually do. For example, when momentum stocks underperform,
                   value stocks typically advance more than average.

                   During the reporting period, the market experienced dra-
                   matic shifts in investor sentiment. In the first quarter of
                   the year the stock market's rally was extremely narrow,
                   limited mostly to a few very large growth companies and the
                   technology sector. As the year progressed, investors ro-
                   tated assets into value-oriented, smaller-cap and cyclical
                   issues. The CORE process resulted in very strong returns
                   during its first three months of operations. However, we
                   prefer stocks with good momentum, and as the market shift
                   occurred in the second quarter, those stocks with the poor-
                   est momentum were the better performers, hurting overall
                   returns.

                   Investment Objective

                   The Fund seeks long-term growth of capital and dividend in-
                   come primarily through a broadly diversified portfolio of
                   large-cap equity securities of U.S. issuers that are sell-
                   ing at low to modest valuations relative to general market
                   measures.

                   The portfolio employs a disciplined approach that combines
                   fundamental investment research provided by Goldman, Sachs
                   & Co.'s Global Investment Research Department and consensus
                   opinions, with quantitative analysis generated by the Asset
                   Management Division's proprietary model. This quantitative
                   system evaluates each stock using many different criteria,
                   including valuation measures, growth expectations, earnings
                   momentum and risk profile. It also objectively analyses the
                   impact of current economic conditions on different types of
                   stocks to determine where the emphasis should be placed.
                   The portfolio construction process evaluates stocks based
                   on their overall expected return and their contribution to
                   portfolio risk. The final portfolio is the one that we be-
                   lieve has the highest potential return for the targeted
                   amount of risk.

                                                                              15

                   change the individual securities it holds, the number or
                   types of securities held and the markets in which it in-
                   vests. References to individual securities do not consti-
                   tute recommendations to the investor to buy, hold or sell
                   such securities. In addition, references to past perfor-
                   mance of the Fund do not indicate future returns, which are
                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   Outlook

                   As always, the Fund remains fully invested in stocks. The
                   Fund's sector weightings and distribution among size cate-
                   gories are targeted to stay close to those of the Russell
                   1000 Value index, as do exposures to other risk factors
                   (such as dividend yield). Based on long-term results, our
                   quantitative process prefers low P/E and low price/book
                   stocks with good momentum characteristics that exhibit sta-
                   bility in stock price and earnings, and that are favored by
                   research analysts. As such, we maintain an exposure to se-
                   curities that display these factors.

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

GOLDMAN SACHS VARIABLE INSURANCE TRUST CORE SMALL CAP EQUITY FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust CORE Small Cap Equity Fund. This semiannual report covers the
 six-month period ended June 30, 1999.

                   Performance Review

                   For the six-month period ended June 30, 1999 the Fund gen-
                   erated a 5.42% cumulative total return. Over the same time
                   period, the Fund's benchmark, the Russell 2000 Index, gen-
                   erated a cumulative total return of 9.28%.

                   The CORE strategy is a well-defined investment process that
                   has historically provided consistent, risk-managed perfor-
                   mance, with a reduced risk that returns will be very dif-
                   ferent from those of a specific benchmark over time.
                   However, much of the reporting period was characterized by
                   a sharp increase in return dispersion (the difference be-
                   tween the best- and worst-performing stocks), among the
                   stocks in our universe. This often impaired the effective-
                   ness of using a systematic approach to stock selection and
                   portfolio construction.

                   In the first quarter of the year, the stock market's rally
                   was extremely narrow, limited mostly to a few very large
                   growth companies and the technology sector. During that pe-
                   riod small- cap stocks fared poorly, and those that did
                   well were companies with no earnings (such as Internet
                   stocks). In contrast, the CORE process typically prefers
                   stocks with earnings. Additionally, the four basic compo-
                   nents that the CORE investment process emphasizes in stock
                   selection did not consistently work well. For example,
                   stocks with poor momentum often fared better than those
                   with good momentum; low beta but volatile stocks did well,
                   as did those that were not favored by research analysts.

                   However, with the economy rising at faster than anticipated
                   rates, investors began focusing on cyclical sectors of the
                   market that tend to be more value oriented. And after a
                   prolonged period of sub-par results, smaller-cap stocks
                   outperformed their larger-cap counterparts in the second
                   quarter. During that period, our investment process per-
                   formed more in line with historical results, and the Fund's
                   15.1% return was similar to that of its benchmark.

                   Investment Objective

                   The Fund seeks long-term capital growth, primarily through
                   a broadly diversified portfolio of equity securities of
                   U.S. issuers with risk characteristics similar to those of
                   the Russell 2000 Index.

                   The portfolio employs a disciplined approach that combines
                   fundamental investment research provided by Goldman, Sachs
                   & Co.'s Global Investment Research Department and consensus
                   opinions, with quantitative analysis generated by the Asset
                   Management Division's proprietary model. This quantitative
                   system evaluates each stock using many different criteria,
                   including valuation measures, growth expectations, earnings
                   momentum and risk profile. It also objectively analyses the
                   impact of current economic conditions on different types of
                   stocks to determine where the emphasis should be placed.
                   The portfolio construc-

                   tion process evaluates stocks based on their overall ex-
                   pected return and their contribution to portfolio risk. The
                   final portfolio is the one that we believe has the highest
                   potential return for the targeted amount of risk.

                   * Opinions expressed in this report represent our present
                   opinions only. References to individual securities should
                   not be construed as commitments that such securities will
                   be retained in the Fund. From time to time, the Fund may
                   change the individual securities it holds, the number or
                   types of securities held and the markets in which it in-
                   vests. References to individual securities do not consti-
                   tute recommendations to the investor to buy, hold or sell
                   such securities. In addition, references to past perfor-
                   mance of the Fund do not indicate future returns, which are
                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   Outlook

                   As always, the Fund remains fully invested in stocks. The
                   Fund's sector weightings and distribution among size cate-
                   gories are targeted to stay close to those of the Russell
                   2000 index, as do exposures to other risk factors (such as
                   dividend yield). Based on long-term results, our quantita-
                   tive process prefers low P/E and low price/book stocks with
                   good momentum characteristics that exhibit stability in
                   stock price and earnings, and are favored by research ana-
                   lysts.

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

GOLDMAN SACHS VARIABLE INSURANCE TRUST CAPITAL GROWTH FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust Capital Growth Fund. This semiannual report covers the six-
 month period ended June 30, 1999.

                   Performance Review

                   For the six-month period ended June 30, 1999 the Fund gen-
                   erated a 13.00% cumulative total return, outperforming the
                   12.38% cumulative total return of its benchmark, the Stan-
                   dard & Poor's 500 Index (with dividends reinvested).

                   The Fund's outperformance was noteworthy, as it occurred
                   during a period when investors rotated out of larger-cap
                   growth stocks in favor of smaller-cap issues. The Fund's
                   selective positions in the technology sector aided perfor-
                   mance. Overall, the Fund was able to capture solid gains in
                   the sector, while avoiding some of the volatility that oc-
                   curred during the period.

                   Investment Objective

                   The Fund seeks long-term capital growth, primarily through
                   investments in a diversified portfolio of companies strate-
                   gically poised for long-term growth.

                   Sector Performance

                   As bottom-up stock pickers, we focus on the real worth of
                   the business, and to the extent that we find several busi-
                   nesses in related industries that we believe have long-term
                   growth potential, the Fund may develop an overweight in a
                   given sector. One such example is the Fund's position in
                   the pharmaceutical sector, which we find fundamentally at-
                   tractive. All of the companies owned in this sector fit the
                   team's strategy, due to their strong business franchises,
                   dominant market positions and growth potential.

                   not be construed as commitments that such securities will
                   be retained in the Fund. From time to time, the Fund may
                   change the individual securities it holds, the number or
                   types of securities held and the markets in which it in-
                   vests. References to individual securities do not consti-
                   tute recommendations to the investor to buy, hold or sell
                   such securities. In addition, references to past perfor-
                   mance of the Fund do not indicate future returns, which are
                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   Outlook

                   While we neither make nor rely on economic forecasts to
                   make investment decisions, we are generally bullish on the
                   U.S. economy. Over the last decade, global communication
                   has increased, resulting from significant technological ad-
                   vances as well as a generally peaceful world political en-
                   vironment. We believe that this trend, combined with
                   favorable demographic trends, will benefit U.S. companies
                   over the long term. More fundamentally, though, the team
                   continues to focus on the core business characteristics
                   which provide a foundation for long-term growth, such as
                   strength of franchise, quality of management, and free cash
                   flow, along with favorable demographic trends. We believe
                   that the enduring competitive advantage of the companies we
                   own--based on the criteria mentioned above--will withstand
                   even an uncertain market environment.

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

GOLDMAN SACHS VARIABLE INSURANCE TRUST MID CAP VALUE FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust Mid Cap Value Fund. This semiannual report covers the six-month
 period ended June 30, 1999.

                   Performance Review

                   For the six-month period ended June 30, 1999 the Fund gen-
                   erated a 16.69% cumulative return and significantly
                   outperformed the 10.33% cumulative return of its benchmark,
                   the Russell Midcap Index.

                   During the first quarter, mid-cap stocks reached a historic
                   low in terms of both performance and valuation relative to
                   growth and large-cap stocks. Believing that the extreme
                   pressure upon these stocks was unsustainable, we maintained
                   conviction in the unrecognized fundamental strength of our
                   existing mid cap value holdings. And, in some cases, in
                   typical value investor fashion, we used the opportunity to
                   both increase and initiate positions at attractive prices.

                   During the second quarter, we witnessed a broadening of
                   market leadership. There were many drivers behind this
                   trend. Monetary easing by central banks around the globe
                   mitigated liquidity concerns surrounding the 1998 financial
                   crisis and restored investor confidence in both domestic
                   and global growth. Signs of global economic strength in-
                   spired investors to venture towards discounted segments of
                   the market, such as economically-sensitive industrials,
                   value stocks and smaller cap names. Additionally, the over-
                   all market closed the second quarter on a positive note in
                   anticipation of strong second quarter earnings announce-
                   ments. As a result, we enjoyed double-digit returns from
                   the majority of our holdings. During the second quarter,
                   the Fund's 19.6% return substantially outperformed the
                   10.9% return of its benchmark. Year-to-date, the Fund
                   outperformed its benchmark by 636 basis points.

                   not be construed as commitments that such securities will
                   be retained in the Fund. From time to time, the Fund may
                   change the individual securities it holds, the number or
                   types of securities held and the markets in which it in-
                   vests. References to individual securities do not consti-
                   tute recommendations to the investor to buy, hold or sell
                   such securities. In addition, references to past perfor-
                   mance of the Fund do not indicate future returns, which are
                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   Name Change

                   Effective May 1, 1999, the Variable Insurance Trust Mid Cap
                   Equity Fund was renamed the Mid Cap Value Fund. The Fund
                   has always and will continue to be managed according to a
                   disciplined value investment style. The name of the Fund
                   was changed merely to better reflect its investment guide-
                   lines.

                   Outlook

                   In recent months, we were reassured to see the Fund's value
                   strategy at work after a period of sub-par results. The
                   second quarter experience reflects the premise behind why
                   value can deliver superior returns over the long term. As
                   in the past, we have seen investors overreact to uncer-
                   tainty or temporary disappointments and drive stock prices
                   and valuations to unsustainable low levels. When stocks are
                   priced according to such low expectations, they are more
                   likely to possess limited downside with potentially signif-
                   icant upside, and these are the investment opportunities
                   for which we search. During such times, even modest im-
                   provements in market conditions or fundamentals can prompt
                   sharp rebounds, as we saw with many of our holdings. We
                   will continue to, with our disciplined first-hand fundamen-
                   tal research process, seek out the neglected and misunder-
                   stood companies that we believe possess the potential to
                   deliver superior long-term returns.

                   We remain enthusiastic about the long-term value offered by
                   mid-cap companies and our portfolio in particular. Despite
                   a strong quarter, we believe that significant upside poten-
                   tial remains in several of our holdings in the Fund. The
                   Goldman Sachs Variable Insurance Trust Mid Cap Value Fund
                   remains significantly discounted relative to both its uni-
                   verse and to large cap stocks (see below).

GOLDMAN SACHS VARIABLE INSURANCE TRUST CORE INTERNATIONAL EQUITY FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust CORE International Equity Fund. This semiannual report covers
 the period from April 1, 1999, when the Fund began operations, through June
 30, 1999.

                   Performance Review

                   From April 1, 1999 through June 30, 1999, the Fund gener-
                   ated a 4.60% cumulative total return. This compares favor-
                   ably with the 2.60% cumulative total return of its
                   benchmark, the Morgan Stanley Capital International Europe,
                   Australia and Far East ("Morgan Stanley EAFE") Index ("MSCI
                   EAFE Index").

                   The CORE strategy is a well-defined investment process that
                   has historically provided consistent, risk-managed perfor-
                   mance, with a reduced risk that returns will be very dif-
                   ferent from those of a specific benchmark over time.
                   Additionally, the diversification of our models typically
                   adds value, because when one theme doesn't work, others
                   usually do. For example, when momentum stocks underperform,
                   value stocks typically advance more than average.

                   The Fund's diversification was a key benefit during the re-
                   porting period, as we experienced dramatic shifts in in-
                   vestor sentiment. In Europe, the market rotated from
                   traditional growth oriented stocks in favor of value
                   stocks. In Japan, our outlook turned more positive, due to
                   value factors and improved market performance. The Fund was
                   rewarded for its underweighted stance in the United King-
                   dom, as our indicators pointed to weak value and momentum
                   measures.

                   Investment Objective

                   The Fund seeks long-term capital growth, primarily through
                   a broadly diversified portfolio of equity securities of
                   large-cap companies that are organized outside the United
                   States, or whose securities are principally traded outside
                   the U.S.

                   The portfolio employs a disciplined approach that combines
                   fundamental investment research provided by Goldman, Sachs
                   & Co.'s Global Investment Research Department and consensus
                   opinions, with quantitative analysis generated by the Asset
                   Management Division's proprietary model. This quantitative
                   system evaluates each stock using many different criteria,
                   including valuation measures, growth expectations, earnings
                   momentum and risk profile. It also objectively analyses the
                   impact of current economic conditions on different types of
                   stocks to determine where the emphasis should be placed.
                   While maintaining a profile close to that of the benchmark,
                   those stocks ranked highly by both the quantitative model
                   and the Goldman Sachs Global Investment Research Department
                   and consensus opinion are selected for the portfolio.

                   * Opinions expressed in this report represent our present
                   opinions only. References to individual securities should
                   not be construed as commitments that such securities will
                   be retained in the Fund. From time to time, the Fund may
                   change the individual securities it holds, the number or
                   types of securities held and the markets in which it in-
                   vests. References to individual securities do not consti-
                   tute recommendations to the investor to buy, hold or sell
                   such securities. In addition, references to past perfor-
                   mance of the Fund do not indicate future returns, which are
                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   Outlook

                   As always, the Fund remains substantially invested in
                   stocks. Our sector and capitalization weightings are
                   targeted to stay relatively close to that of the MSCI EAFE
                   index, as are exposures to other risk factors (such as div-
                   idend yield). Based on our investment strategy, we are em-
                   phasizing a diversified portfolio of lower P/E stocks with
                   solid momentum characteristics, in order to identify stocks
                   with strong growth potential.

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

                GOLDMAN SACHS VARIABLE INSURANCE TRUST INTERNATIONAL EQUITY FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust International Equity Fund. This semiannual report covers the
 six-month period ended June 30, 1999.

                   Performance Review

                   For the six-month period ended June 30, 1999 the Fund gen-
                   erated a 2.69% cumulative total return. Over the same time
                   period, the Fund's benchmark, the FT/Actuaries EuroPac To-
                   tal Return Index (unhedged with dividends reinvested) gen-
                   erated a cumulative total return of 5.35%.

                   The Fund's underperformance versus its benchmark was due to
                   sector and asset allocation strategies. The Portfolio was
                   hurt by its underweight in Japan and Asia, as it favored
                   the weaker-performing European market. Performance was fur-
                   ther muted due to a strong shift in investor sentiment from
                   growth to value and cyclical issues as the year progressed.

                   In Europe, most equity markets rebounded to start the year,
                   as most central banks lowered interest rates to facilitate
                   convergence in advance of the monetary union. In addition,
                   countries like France, Italy and Germany used lower inter-
                   est rates as a means improving consumer and business confi-
                   dence to try and stave off a recession. The euphoria
                   surrounding the launch of the euro was short lived, as the
                   markets retreated on news of the peso devaluation, rising
                   U.S. interest rates and sluggish production data in much of
                   the region.

                   The Japanese market advanced strongly during the period on
                   the back of improved investors' sentiment. Expectations for
                   earnings recovery in late 1999 were substantially enhanced
                   by a number of statistics indicating that the worst was be-
                   hind.

                   Asian stocks produced strong results, as signs pointed to
                   economies in the region rebounding much faster than antici-
                   pated. Investors who were previously underweight in the re-
                   gion moved to increase their exposure, creating an
                   attractive investment environment.

                   Investment Objective

                   The Fund seeks long-term capital growth, primarily through
                   equity securities of companies that are organized outside
                   the United States or whose securities are principally
                   traded outside the United States.

                                                                              43

                   Outlook

                   Europe--We continue to invest in quality undervalued stocks
                   that have strong growth opportunities. Such stocks are lo-
                   cated in a wide variety of sectors. At present, the most
                   favored sector is telecommunications, where both technolog-
                   ical advance and consolidation on both a European and
                   global level are proceeding at a rapid pace. In addition,
                   certain electronic, service and leisure companies remain
                   favored selections. While the sector rotation towards value
                   stocks has made the past quarter challenging, we continue
                   to believe in the structural growth of the aforementioned
                   sectors.

                   Japan--For the time being, we remain cautious on the market
                   given the recent rally and the concerns of equity valua-
                   tions. Based on the current price levels, the market seems
                   to have discounted much of earnings recovery expected to
                   materialize in late 1999. On a positive note, many compa-
                   nies are in the process of implementing restructuring plans
                   that they announced several months back--benefits of which
                   could improve earnings. Key to sustainability of market
                   strength will be profit trends in coming years. If we be-
                   come convinced of the sustainability of corporate earning
                   growth next year onward, we may need to revise our stance.

                   Asia--Our outlook on Asia as a region has improved, al-
                   though it is important to note that intra-regional discrep-
                   ancies still exist. We believe that several countries have
                   "bottomed out" and are now showing signs of recovery fol-
                   lowing the crisis of 1998. The best performers over the
                   last six months were South Korea and Thailand, where the
                   continued downtrend in interest rates and significant fi-
                   nancial sector restructuring resulted in stock market ral-
                   lies of 246% and 31%, respectively. In addition, we expect
                   to see improving performance in the commodity-driven coun-
                   tries such as Australia, following increasing demand in
                   Asia and a more positive regional and global outlook. On a
                   cautious note, we recognize that a recovery in Asia is very
                   dependent on the continued strength of the U.S. market.
                   Consequently, we will be closely monitoring all economic
                   data to come out of the U.S. in an effort to determine its
                   impact on the Asian markets.

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

           GOLDMAN SACHS VARIABLE INSURANCE TRUST SHORT DURATION GOVERNMENT FUND
Shareholder Letter
 Dear Shareholder,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust Short Duration Government Fund. This semiannual report covers
 the period from April 1, 1999, when the Fund began operations, through June
 30, 1999.

                   Performance Review

                   From April 1, 1999 through June 30, 1999, the Fund gener-
                   ated a (0.20)% cumulative total return. During that period
                   the Fund's benchmark, a Two-Year U.S. Treasury Security,
                   had a 0.30% cumulative total return. The Fund's relative
                   underperformance was attributable, in large part, to the
                   general widening of non-Treasury spreads that has taken
                   place since inception of the Fund.

                   Investment Objective

                   The Fund seeks a high level of current income and second-
                   arily, in seeking current income, may also consider the po-
                   tential for capital appreciation. The Fund invests
                   primarily in securities that are issued or guaranteed by
                   the U.S. government, its agencies, instrumentalities or
                   sponsored enterprises.

                   not guaranteed and will vary. Furthermore, the value of
                   shares of the Fund may fall as well as rise.

                   Outlook

                   Given recent cheapening, we are generally optimistic re-
                   garding the prospects for the mortgage and asset-backed
                   markets. However, the pace at which spreads compress going
                   forward will depend on numerous, yet-to-be-resolved fac-
                   tors, including the direction of the Federal Reserve
                   Board's policy, the behavior of spread sectors in general,
                   and the impact of Y2K on investors' willingness to tolerate
                   risk.

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

GOLDMAN SACHS VARIABLE INSURANCE TRUST GLOBAL INCOME FUND
Shareholder Letter
 Dear Shareholders,
 We are pleased to report on the performance of the Goldman Sachs Variable In-
 surance Trust Global Income Fund. This semiannual report covers the six-month
 period ended June 30, 1999.

                   Performance Review

                   For the six-month period ended June 30, 1999, the Fund gen-
                   erated a (1.45)% cumulative total return. Over the same
                   time period, the Fund's benchmark, the JP Morgan Global
                   Government Bond Index (hedged into U.S. dollars), generated
                   a cumulative total return of (0.24)%.

                   The greatest contributor to underperformance was the Fund's
                   underweight Japanese bond allocation. Despite ongoing fears
                   of further fiscal stimulus (and therefore increased bond
                   supply) the Bank of Japan continued to supply liquidity to
                   the market, driving short-term interest rates (i.e. 1 year
                   or less) to below 10bps. This liquidity found its way pro-
                   gressively along the yield curve, as banks took the oppor-
                   tunity to purchase longer dated bonds - thereby driving
                   down yields.

                   Also contributing to underperformance was a dramatic flat-
                   tening in the U.S. yield curve between 10- and 30-year ma-
                   turities. Unfortunately, the positive impact of the Fund's
                   underweight duration position in the U.S. was more than
                   offset by the negative impact of the flattening yield
                   curve, as the portfolio was overweight in the 10-year sec-
                   tor relative to the 30-year sector.

                   Investment Objective

                   The Fund seeks high total return, emphasizing current in-
                   come 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.

                   Outlook

                   In the short-term, the inflation outlook and prospect for
                   the U.S. economy may result in further action by the Fed-
                   eral Reserve Board. Over the longer term, we believe that
                   the U.S. economy will remain strong, and that could dampen
                   sentiment for Treasuries.

                   In Europe, while we agree that the economy will start to
                   recover in the second half of 1999, inflation remains under
                   control. Market sentiment is currently fragile and European
                   bonds are unlikely to rally substantially without a sus-
                   tainable recovery of Euro currency. However, the 100 basis
                   points of rate hikes priced into the curve by this time
                   next year seems too pessimistic in our view. As a result,
                   we have taken the opportunity to place a small Europe-U.S.
                   relative value trade for the portfolio, based on the rela-
                   tive economic fundamentals of U.S. and Europe. We will con-
                   sider a larger position if the Euro starts to appreciate.
                   The European Central Bank is likely to continue to provide
                   an accommodative monetary background to protect the moder-
                   ate pace of economic recovery currently in evidence.

                   In Japan, we continue to see a very accommodative fiscal
                   and monetary policy framework. This is causing Japanese
                   government bonds to trade in a relatively narrow range, al-
                   though volatility remains high.

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

 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. Actual results
 could differ from those estimates.

 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 last bid price. Unlisted equity
 and debt securities for which market quotations are available are valued at
 the last sale price on valuation date, or if no sale occurs, at the last bid
 price. Short-term debt obligations maturing in sixty days or less are valued
 at amortized cost. Restricted securities, and other securities for which quo-
 tations are not readily available, are valued at fair value using methods ap-
 proved by the Board of Trustees.

 B. Securities Transactions and Investment Income -- Securities transactions
 are recorded as of the trade date. Realized gains and losses on sales of in-
 vestments are calculated on the identified-cost basis. Dividend income is re-
 corded on the ex-dividend date. Dividends for which the fund has the choice
 to receive either cash or stock are recognized as investment income in an
 amount equal to the cash dividend. Interest income is determined on the basis
 of interest accrued, premium amortized and discount earned. Growth and Income
 and Global Income do not amortize premiums. In addition, it is the Funds'
 policy to accrue for estimated capital gains taxes on foreign securities held
 by the Funds, which are subject to such taxes.

 C. Foreign Currency Translations -- Amounts denominated in foreign currencies
 are translated into U.S. dollars on the following basis: (i) investment valu-
 ations, other assets and liabilities initially expressed in foreign curren-
 cies 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 exchange rates
 prevailing on the respective dates of such transactions.
   Net realized and unrealized gain (loss) on foreign currency transactions
 will represent: (i) foreign currency exchange gains and losses from the sale
 and holdings of foreign currencies; (ii) 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 interest and dividend recorded and the amounts actually received.

 D. Forward Foreign Currency Exchange Contracts -- CORE International Equity,
 International Equity, Global Income, Growth and Income, Capital Growth and
 Mid Cap Value 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 International Equity, International Equity and
 Global Income may also purchase and sell forward contracts to seek to in-
 crease total return. All commitments are "marked-to-market" daily at the ap-
 plicable translation rates and any resulting unrealized gains or losses are
 recorded in each Fund's financial statements. The Funds record realized gains
 or losses at the time the 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.

 E. Mortgage Dollar Rolls -- Global Income and Short Duration Government may
 enter into mortgage "dollar rolls" in which the Fund sells securities in the
 current month for delivery and simultaneously contracts with the same
 counterparty to repurchase similar (same type, coupon and maturity) but not
 identical securities on a specified future date. During the roll period, the
 Fund loses the right to receive principal and interest paid on the securities
 sold. However, the Fund benefits to the extent of any difference between the
 price received for the securities sold and the lower forward price for the
 future purchase (often referred to as the "drop") or fee income plus the in-
 terest earned on the cash proceeds of the securities sold until the settle-
 ment date of the forward purchase. The Fund will hold and maintain in a
 segregated account, until the settlement date, cash, liquid assets or high-
 grade debt securities in an amount equal to the forward purchase price. For
 financial reporting and tax reporting purposes, the Fund treats mortgage dol-
 lar rolls as two separate transactions; one involving the purchase of a secu-
 rity and a separate transaction involving a sale.

 F. Futures Contracts -- The Funds may enter into futures transactions to
 hedge against changes in interest rates, securities prices, currency exchange
 rates or to seek an increase of 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 futures exchange on which the contract is traded.
 Payments for marked to market on 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 equal to the difference between the value of the futures con-
 tract to sell and the value of futures contract to buy. Gains and losses are
 reported in the Statements of Operations.

                                                                              67

   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.

 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. 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 to its shareholders. Accordingly, no federal tax pro-
 visions 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.
   As of December 31, 1998, the following Funds had capital loss carryforwards
 for U.S. federal tax purposes. This amount is available to be carried forward
 to offset future capital gains to the extent permitted by applicable laws or
 regulations.

 I. Deferred Organization Expenses -- Organization-related costs are being am-
 ortized on a straight-line basis over a period of five years. Included in
 "Accrued expenses and other liabilities" in the accompanying Statements of
 Assets and Liabilities, Capital Growth and Mid Cap Value Funds owed $8,367
 and $8,365, respectively, to an affiliate for organizational expenses in-
 curred for the period ended June 30, 1999.
   The deferred organization costs for Growth and Income, International Equity
 and Global Income Funds each have an unamortized period remaining through
 January 12, 2003; the CORE U.S. Equity, CORE Large Cap Growth and CORE Small
 Cap Equity Funds each have an unamortized period remaining through February
 13, 2003; the Capital Growth and Mid Cap Value Funds have an unamortized pe-
 riod remaining through April 30, 2003 and May 1, 2003, respectively.

 J. Expenses -- Expenses incurred by the Trust that do not specifically relate
 to an individual portfolio of the Trust are generally allocated to the port-
 folios on a pro-rata basis.

 K. Segregatable Transactions -- As set forth in the prospectus, certain Funds
 may enter into transactions to seek total return such as forward foreign cur-
 rency exchange contracts, futures contracts, written options, mortgage dollar
 rolls, when issued and forward commitments that require the Funds to segre-
 gate assets on the accounting records equal to or greater than the market
 value of the corresponding transactions. It is each Fund's policy to maintain
 liquid assets as collateral to cover these requirements.

   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 June 30,
 1999, International Equity and Global Income had sufficient cash and/or secu-
 rities to cover any commitments under these contracts.
   The International Equity and Global Income Funds have recorded a "Receiv-
 able for forward foreign currency exchange contracts" and "Payable for for-
 ward foreign currency exchange contracts" resulting from "open" and "closed
 but unsettled" forward foreign currency exchange contracts of $12,450 and
 $26,126 and $67,867 and $5,135, respectively, in the accompanying Statement
 of Assets and Liabilities.

   For the period ended June 30, 1999, the Trust paid Goldman Sachs approxi-
 mately $461 of brokerage commissions from portfolio transactions.

 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 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 June 30, 1999, Growth and Income, CORE U.S. Equity, CORE Large Cap
 Growth, Capital Growth, Mid Cap Value and Short Duration Government had undi-
 vided interests in the repurchase agreements in the following joint account
 which equaled $3,900,000, $400,000, $1,000,000, $100,000, $2,400,000 and
 $200,000, respectively, in principal amount. At June 30, 1999, the following
 repurchase agreements held in this joint account were fully collateralized by
 Federal Agency obligations.

 7. LINE OF CREDIT FACILITY

 The Funds participated in a $250,000,000 uncommitted, unsecured revolving
 line of credit facility. Under the most restrictive arrangement, each Fund
 must have owned securities having a market value in excess of 300% of the to-
 tal bank borrowings. Effective April 30, 1999, the Funds now participate in a
 $250,000,000 uncommitted unsecured revolving line of credit facility and a
 $250,000,000 committed unsecured revolving line of credit facility. Under the
 most restrictive arrangement, each Fund must own securities having a market
 value in excess of 400% of the total bank borrowings. These facilities are to
 be used solely for temporary or emergency purposes. The interest rate on
 borrowings is based on the Federal Funds rate. The committed facility also
 requires a fee to be paid by the Funds based on the amount of the commitment
 which has not been utilized. During the six months ended June 30, 1999, the
 Funds did not have any borrowings under any of these facilities.

                                                                              75
