Dear Shareholder of The GCG Trust:
 
We are pleased to present the 1998 Semi-Annual Report of the GCG Trust (the
"Trust"). The following report provides information about the performance and
financial position of the portfolios in the Trust.
 
During the first six months of 1998, the net assets of the Trust increased 31%
to end the period at $2.0 billion. This increase can be attributed to new
investment by shareholders and strong investment returns.
 
The U.S. stock market continued to generate strong returns during the first half
of 1998. However, performance varied significantly across different sectors of
the market:
 
     -  Large company stocks provided the highest returns during the six-month
        period. The Standard & Poors 500 Index (an index of large-cap stocks)
        had a total return of 17.71%. The Russell 2000 Index (an index of
        small-cap stocks) had a total return of only 4.93% over the same period.
 
     -  Aggressive, growth-oriented stocks had significantly higher returns than
        more conservative, value-oriented stocks. During the first half of the
        year, the Standard & Poors 500/Barra Growth Index had a total return of
        23.07%. The Standard & Poors 500/Barra Value Index returned only 12.13%.
 
Over short periods of time, different sectors of the market can produce
significantly different returns. Consequently, investment portfolios can also
produce substantially different returns. When you evaluate the performance of a
portfolio, it is important to understand its investment strategy. It is also
important to focus on performance over longer periods.
 
Through your variable annuity contract, you have access to many portfolio
managers with extensive investment experience. We believe that these managers
can provide superior investment results over time.
 
We are committed to providing quality products and services to shareholders, and
we look forward to helping you meet your financial objectives. Thank you for
your continued support.
 
Sincerely,
 
/s/ Fred S. Hubbell

                                 THE GCG TRUST
                                SMALL CAP SERIES

The Small Cap Series (the "Series") seeks to achieve long-term capital
appreciation. During the first six months of 1998, the Series had a total return
of 17.13%. The Russell 2000 Index had a total return of 4.93% over the same
period.

Following a particularly volatile fourth quarter of 1997, small company growth
stocks stumbled into 1998 with attractive relative valuations. The continuation
of low interest rates and low inflation restored investor confidence. This
renewed confidence helped quell the liquidity concerns associated with small-cap
stocks and investors turned to these stocks in an effort to capture their
explosive growth potential.

The Series benefited from this trend, posting a first quarter return of 13.89%
versus 10.06% for its benchmark, the Russell 2000 Index. Thus, the first quarter
of 1998 was favorable on both a relative and absolute basis. Relative
performance was boosted in part by the Series having no exposure to utility and
energy stocks, two poor performing sectors.

Additional value was added through strong performance by several key holdings.
The top performing holding held for the entire quarter was Central Garden & Pet
Company, which was up 48.8%. This leading distributor of lawn and pet supplies
appreciated on an anticipated increase in revenues and earnings resulting from
two acquisitions.

Other strong performing stocks included Hooper Holmes Inc. with a total return
of 46.8%. This conductor of medical exams for health and life insurance
companies once again beat analysts' earnings expectations.

During the second quarter, small-cap growth stocks reverted back to a pattern of
unimpressive performance that has plagued this discipline since the summer of
1996. Amid this difficult environment, the Series returned 2.85% versus a
(4.66)% return posted by the Russell 2000 Index.

The Series' strong relative return was not the result of any particular sector
weightings but was achieved through the performance of a handful of holdings
across several industries. Specifically, Medquist Inc., Skywest Inc. and
Earthgrains Company, a health care information services company, an airline and
a bread company respectively, realized quarterly returns ranging from 26.4% to
56.9%.

Overall, our investment strategy will remain unchanged for the second half of
1998. We will continue to actively and aggressively seek out, research and
invest in America's fastest growing companies. Regardless of market conditions,
we feel that the only way we are able to sustain superior long-term performance
is through an uncompromising commitment to a consistent approach.

                               ALL-GROWTH SERIES
 
The All-Growth Series (the "Series") seeks capital appreciation. For the first
six months of 1998, the Series had a total return of 10.24%. The Russell Midcap
Index had total return of 9.13% over the same period.

The Series invests in small/mid-cap companies with high rates of earnings
growth. Most of the positive performance occurred in the first quarter. Results
were up modestly in the second quarter as continued problems in Asia raised
investor concern and added to the market's volatility.

The top holdings of the fund did especially well, including J.D. Edwards &
Company, Ascend Communications Inc. and HBO & Company. America Online Inc. and
Uniphase Corporation also achieved large gains. Dura Pharmaceuticals Inc., BJ
Services Company and ATMI Inc. all experienced lowered earnings expectations,
and as a result, their stocks weakened during the first half.

The portfolio remains overweighted in service and technology stocks which
represent 23% and 33% of the total fund respectively. The service sector
includes solid waste management companies, information technology companies and
telecommunication service providers.

The sector weightings reflect mainly our growth company bias. Underweighted
sectors include financials, basic industry and capital goods stocks. The
companies in the portfolio, on average, continue to grow earnings at rates above
50%.

It is important to point out that growth stocks, small, mid and large cap,
outperformed value stocks year-to-date. While we are encouraged by this recent
reversal within the growth market, we continue to face a market that favors
large-cap stocks over smaller stocks. This is occurring even though earnings for
mid-cap companies are accelerating, while earnings estimates for large-cap
companies are decelerating.

When the results for the second quarter of 1998 are available, we expect the
small and mid-cap segments of the market will post profit growth rates that
surpass that of the large caps, making it the fifth consecutive quarter of
superior relative growth.

                          CAPITAL APPRECIATION SERIES

The Capital Appreciation Series (the "Series") seeks to generate long-term
capital growth. During the first six months of 1998, the Series had a total
return of 11.84%. The Standard & Poors 500 Index (the "S&P 500") had a total
return of 17.71% over the same period.

After a robust first quarter, the equity market paused in the second quarter
amid renewed concerns that Asia's problems will spread and weaken global demand
and profit margins. Commodity based industries, such as energy, paper and
chemicals, saw earnings expectations wane with the Dow Jones Industrials gaining
only 2.2% for the quarter.

While a lower interest rate outlook was positive, the strong dollar and
questions about the strength of European and Latin American economies kept
investors nervous. Large cap growth stocks, benefiting from the perception of
stable earnings delivery, led the way widely outperforming large-cap value
issues. Mid and small-cap stocks fared poorly, falling well behind the large cap
sector.

The Series benefited most from exposure to consumer oriented stocks (Ford Motor
Company, Home Depot Inc., Time Warner Inc. and Comcast Corporation), healthcare
(Warner Lambert Company, Schering Plough Corporation and Glaxo Wellcome PLC),
and technology (Microsoft Corporation and HBO & Company).

Although the portfolio is decidedly large-cap in orientation, the Manager is
finding better value in mid-cap names in regards to future purchases. Also, the
Manager is favoring dividend yield when available, as it will hopefully provide
a buffer in any market pullbacks.

Late during the second quarter, the portfolio tilted towards a slightly more
defensive posture. The value component was increased to 55% with the growth
segment reduced to 45% (a 10% shift from the prior position). Given the
financial backdrop, the Portfolio Manager believes high quality, stable growth
issues that deliver expected earnings should continue to benefit from healthy
valuations.

The Portfolio Manager finds these investments predominantly in the healthcare,
consumer products and mature technology industries. However, realizing the
current overall level of the market, the Series has an increased exposure to
value oriented, higher yielding securities.

Overall, the portfolio's characteristics are in line with or slightly less
aggressive than that of the broad market. The Portfolio Manager believes that
the next few quarters will reward fundamental stock selection and the avoidance
of undue market risk.

                              VALUE EQUITY SERIES

The objective of the Value Equity Series (the "Series") is capital appreciation
and, secondarily, dividend income. The Series had a total return of 0.62% for
the first six months of 1998. Over the same time period, the Standard & Poors
500 Index ("S&P 500") had a total return of 17.71%.

The Series invests in stocks that are priced at a discount to their estimated
intrinsic value. These stocks usually have lower price/earnings and price/book
ratios. During the first half of 1998, these "value-oriented" stocks trailed the
market. The S&P 500/Barra Value Index represents the stocks in the S&P 500 with
the lowest price/book ratios. This index produced a six-month return of only
12.13%.

The Series also has a significant mid-cap component. Mid- cap stocks trailed the
market for the first six months of 1998 as well. The Russell Midcap Index had a
return of only 9.14% for the first six months of 1998.

For the last few quarters, one of the only stock sectors that has had superior
returns are those of large, domestic growth companies for many reasons,
including a rush of foreign investors seeking refuge in high quality securities.
Investors who did not own the stocks of the 100 largest growth stocks in the
U.S. during the past six months, in general, did not keep up with the market.

The portfolio had significant weighting in two industries that dropped during
the first six months of the year: tobacco and oil stocks. Within the S&P 500 at
the sector level, tobacco and oil exploration and production equities were down
an average of 12.05% and 9.27% respectively.

Although these industries had disappointing performance, the positions the
Series holds in these two areas remain undervalued and the Portfolio Manager
continues to be positive about the holdings potential to outperform long-term.

Oil stocks took a tumble as prices dropped due to continued global oversupply.
A reduction in demand from Asian countries pushed oil prices down further.

Tobacco stocks dropped as a new bill in Congress increased the settlement payout
to more than $500 billion. The stocks recovered slightly when the bill fell
through in June. Due to the uncertainty of the lawsuits still pending, the stock
prices remain under pressure and the Manager believes the securities are
undervalued.

Performance was also negatively affected by the Series' significant position in
Sunbeam Corporation. Sunbeam's stock price dropped due to weak sales and
negative publicity regarding improper accounting practices. The Portfolio
Manager was able to sell-off the position quickly to minimize the loss. However,
he began buying it back when the price fell below its perceived value. After he
began buying it back, more problems surfaced and the price dropped further.

The Rising Dividends Series (the "Series") seeks capital appreciation and,
secondarily, dividend income. During the first six months of 1998, the Series
had a total return of 14.32%. The Standard & Poors 500 Index ("S&P 500") had a
total return of 17.71% over the same period.

For the first half of the year, the Portfolio's largest weightings were in the
consumer staples, financial, and technology sectors. The Portfolio's strongest
relative performance was in the financial sector. Notable standouts included
Morgan Stanley Dean Witter & Company and Franklin Resources Inc. (which was
added to the S&P 500 in April).

Another one of the financial companies held in the portfolio, General Re
Corporation, announced in June it would be acquired by Berkshire Hathaway Inc.
for $276.40 a share in common stock of Berkshire Hathaway Inc. This offering
represents a substantial premium above what the Series originally paid for this
holding.

The second quarter ending June 30, 1998, proved to be a period of "correction
and consolidation" for the U.S. equity markets. The technology holdings
negatively impacted the portfolio's performance.

Electronic Data Systems Corporation, Hewlett Packard Company, and Linear
Technology Corporation all suffered from what the Portfolio Manager believes are
short term issues. The Portfolio Manager continues to be optimistic about these
holdings and has used the short term price corrections as an opportunity to
increase those positions.

With the respect to the recent concerns in Asia, the Portfolio Manager does not
believe that the U.S. economy will be materially affected. Nevertheless, the
Portfolio Manager does not expect a quick resolution of the problems. It is
unlikely that this situation will be considered normalized before mid-1999 at
the earliest.

Fortunately, the Asian Crisis has made U.S. dollar-denominated assets
relatively more attractive. Inflows into U.S. stock and bond funds have been
very strong, and this demand has had a positive impact on stock and bond prices.

The Portfolio Manager continues to believe that major-trend favorable factors --
including low inflation and stable interest rates, increased savings rates by
baby boomers, a highly productive corporate sector, technological innovation, a
fiscally responsible government and a strong and stable currency -- are still
intact for a continuation of the positive stock market results investors have
been enjoying for the past few years.

                            STRATEGIC EQUITY SERIES
 
The Strategic Equity Series (the "Series") seeks to achieve capital
appreciation. During the first six months of 1998, the Strategic Equity Series
provided a total return of 6.60%. The Russell Midcap Index and the Russell 2000
Growth Index had total returns of 9.13% and 4.93%, respectively.

The Series screens a universe of 1,500 stocks with an average market
capitalization of $2.8 billion. The average market capitalization of the Series
is approximately $2 billion, which is at the low end of the range for mid-cap
funds. Market capitalization is calculated by multiplying the number of a
company's outstanding shares by the price per share.

The Series' size exposure hurt returns during the first half of the year, a
period characterized by the very largest stocks leading the market. It is
important to note, however, that the Portfolio Manager does not choose stocks
based exclusively on size. Rather, the Portfolio Manager looks for stocks that
have favorable relationships between their growth and value characteristics.

At this point, the stocks that fit the strategy's parameters are on the smaller
end of the mid-cap spectrum, mainly because the current valuations of many
larger stocks are high relative to their historic norms.

On the growth side, the Series invests in stocks whose earnings have increased
at an above-average pace and are likely to continue growing. When choosing
income stocks, the Portfolio Manager looks for stocks that have strong dividend
growth and stability. During the first half of 1998, the Series' growth stocks,
buoyed by low interest rates and strong momentum, significantly outperformed the
Series' income stocks.

The trend, however, reversed in the second quarter as increased volatility
negatively impacted growth stocks with high price-to-earnings ratios. The P/E
ratio is calculated by dividing the price of a stock by its earnings per share.
Essentially, the higher the P/E, the more an investor is paying for a company's
earnings growth.

The Series' financial and transportation holdings performed well. Financial
stocks benefited from a wave of consolidation and low interest rates, while low
oil prices bolstered the transportation sector.

On the income side, consumer cyclicals and capital goods helped returns. Though
the Series holds selected technology issues, it is underweighted in the group
because of its below average earnings trend.

The allocation to utilities dragged down performance slightly. The Series is
still overweighted in the sector, however, because of their very low valuations
and improving profit margins.

                          GROWTH OPPORTUNITIES SERIES

The Growth Opportunities Series (the "Series") seeks capital appreciation.
During its first five months of operations, through June 30, 1998, the Series
had a total return of 3.10%. Over the same time period, the Standard and Poors
500 Index (the "S&P 500") and the Russell Midcap Index had returns of 10.45% and
4.97%, respectively.

The Series invests primarily in equity securities of domestic companies whose
market capitalization is greater than $1 billion, with a focus on mid-cap
stocks. We seek to identify stocks with superior growth potential by identifying
companies with positive, long-term fundamental changes in their business,
revenues, or earnings.

Next we conduct our own research to determine the validity and sustainability of
this change. Lastly, we consider the value of the shares and future potential
for the share price. Stocks that are selected have both outstanding growth
opportunities and attractive valuations.

The period was a frustrating one for mid-cap stocks as they trailed the market
for the first six months of 1998.

Large-caps stocks continued to outperform based on their liquidity and perceived
safety, despite the superior valuations and growth characteristics of many
mid-sized companies. Negative corporate earnings news, combined with continued
turmoil in Japanese and Southeast Asian markets, fueled a so-called "flight to
quality" away from small and mid-capitalization stocks.

This market environment influenced the portfolio. Consumer-oriented stocks
benefited while those in industries sensitive to business cycles
under-performed. For example, the TJX Companies, Inc. and Nordstrom Inc., both
retailing companies, were good performers while the holdings in chemicals (The
Dow Chemical Company and Nalco Chemical Company, for example) and steel
(Carpenter Technology Corporation) lagged.

As of June 30, 1998, the Portfolio Manager believes the Series is positioned for
excellent growth opportunities when the market turns from its attraction to the
new "Nifty 50" of large-cap stocks and again recognizes companies offering both
growth potential and good valuations. The Series has emphasized such stocks,
particularly those with new management teams committed to increasing their
profitability and shareholder returns.

Although Asia's slump is negatively affecting the U.S. economy and its financial
markets, the Portfolio Manager believes that the relative under-performance of
mid-cap companies is generating superior investment opportunities for the coming
months.

                             MANAGED GLOBAL SERIES
 
The Managed Global Series (the "Series") seeks capital appreciation. For the six
months ended June 30, 1998, the Series gained 20.68%. This compares to a 14.77%
for the Morgan Stanley Capital International All Country World Free Index.

Stock selection was the principal driver behind the strong performance. Market
selection also contributed positively. The Series benefited from an overweighted
Europe and an underweighted Asia.

The Series was weighted neutrally relative to the United States. That weighting
was then reduced in favor of additional exposure to Europe. This decision
detracted from performance. As investors became concerned over spillover effects
in Europe from Asia they returned to the perceived safe haven of the U.S. dollar
and equity market.

Cable stocks, software and IT service companies, telecom equipment and consumer
staples performed well, benefiting from an acceleration in merger and
acquisition activity, particularly in the telecom and telecom equipment
industries. Top-performing stocks included America OnLine Inc. in the U.S.
technology sector, Dell Computer Corporation in the PC industry sector, Banca di
Roma in the financial sector and Mannesmann in the capital goods sector.

The positions in software stocks such as Microsoft Corporation and SAP AG
contributed significantly to performance. Recently, the technology sector
exposure was reduced by eliminating the computer hardware and semiconductor
stocks from the portfolio. The outlook for this group has sharply deteriorated;
companies are suffering from overcapacity and weakening demand, leading to poor
pricing and therefore declining earnings growth.

The portfolio continues to be overweighted in Europe, specifically France,
Italy, and the Netherlands. In Europe, much of the exposure has been shifted
away from sectors that have the most direct exposure to Asia. The Series is
underweight in Japan, the United Kingdom, and emerging markets.

The Portfolio Manager currently finds attractive growth opportunities in the
following industries: cable, cellular, financial services, supermarkets,
drugstores, software, and telecommunications equipment. The Series is broadly
underweighted in energy and utilities.

From an earnings standpoint, the Portfolio Manager continues to monitor the
situation in Asia, both in terms of stocks in these markets and also with regard
to the potential impact of continued economic problems on other regions beyond
the Pacific Basin.

We continue to find good earnings growth in both Europe and the United States.
In Europe, we believe the pace of growth will pick up in the second half of the
year. U.S. economic indicators point to the possibility of a weaker second half,
increasing the importance of earnings sustainability.

                            EMERGING MARKETS SERIES
 
The Emerging Markets Series (the "Series") seeks long-term capital appreciation.
For the six months ended June 30, 1998, the Series had a total return of
(15.11)%. Over the same period, the Morgan Stanley Capital International
Emerging Markets Free Index (the "benchmark") had a total return of (18.87)%.

The Asian component of the benchmark declined 22.4% for the six-month period,
while the Latin American component declined 19.8% and the European component
lost 17.2%.

Some of the most positive stock selections were in markets that were hardest hit
during the period. For example, in Malaysia the portfolio return was boosted by
an emphasis on defensive, non-index stocks, such as PPB Oil Palms (a palm oil
producer) and Berjaya Sports Toto (a gaming company). Both stocks significantly
outpaced the Malaysian index.

Largely avoiding Indonesia contributed positively to portfolio performance given
the significant depreciation in that country's currency. An overweight in the
Philippines enhanced performance, as that market has performed significantly
better than its more troubled Asian neighbors.

The Series benefited from positive stock selection in Brazil, primarily the
result of the heavy exposure to the soon-to-be-privatized telecommunications
sector and the low exposure to the electric utility sector. Exposure to Turkish
financials also enhanced performance.

Stock selection in India hurt performance, largely because of a contraction of
premiums in stocks available to foreigners.

Given the renewed concerns for the Asian economies and the political tensions in
the subcontinent, we have been shifting country weightings at the margin toward
Latin America and emerging Europe, where the investment environment is
significantly better.

Although Latin American economies are slowing from the rapid pace of growth of
the previous quarter, we are finding attractive opportunities on the individual
stock level.

Emerging European markets are continuing to benefit from the positive sentiment
that surrounds the coming of the common currency in developed Europe. The
anticipation that convergence of interest rates and inflation rates in the
region is a boon not only to core Europe, but also to peripheral markets such as
Portugal, Greece, Hungary and Poland.

For the longer term we believe that emerging markets represent attractive
opportunities at the current price, economic growth, and valuation levels.
Shares have fallen to historic lows and more than reflect the sober environment
in markets such as Asia, Russia, and the Indian subcontinent.

                            DEVELOPING WORLD SERIES
 
The Developing World Series (the "Series") seeks capital appreciation. During
its first five months of operations, through June 30, 1998, the Series had a
total return of (17.40)%. The Morgan Stanley Capital International Emerging
Markets Free Index had a return of (16.73)% over the same time period.

The Series seeks capital appreciation by investing primarily in the equity
securities of companies in countries having economies and markets generally
considered by the World Bank to be emerging or developing.

Emerging Markets were highly volatile during the period. A declining yen and a
recession in Japan renewed worries that Southeast Asian economies would suffer
another round of currency devaluations. The financial turmoil was aggravated by
non-economic events, including the resignation of Indonesian president Suharto
and nuclear testing in India.

Given Asia's negative economic outlook, the Series' position has been to
underweight its exposure relative to the benchmark in Asia, except for
China/Hong Kong. Among other major emerging markets, the Series remains
overweighted in Brazil and South Africa (an economy largely insulated from Asia,
apart from commodities) and underweighted in Mexico.

The Portfolio Manager views Brazil positively because it is maintaining a
long-term course toward stronger fiscal, monetary and economic systems,
particularly through its privatization programs. Brazilian companies offer
attractive valuations with the promise of continuing positive corporate earnings
growth.

Similarly, South Africa has undertaken corporate restructuring, and a consumer
spending boom offers attractive valuations. The Portfolio Manager believes that
the current pressure on interest rates and the currency is only a short-term
concern.

Overall, the Series' positions in Asia, Brazil, and Mexico boosted performance
during the period while China/Hong Kong held performance back.

The Portfolio Manager views the current turmoil in these markets as a necessary
prerequisite for their long-term economic and market out-performance. Many
developing markets are in various stages of economic reform with stocks selling
at attractive valuations.

In addition, these markets offer growth potential not simply because stock
prices are down, but because of powerful trends toward long-term global
prosperity. For aggressive, long-term investors, now may be the time to maintain
or increase investment in this Series.

                               HARD ASSETS SERIES
 
The Hard Assets Series (the "Series") seeks long-term capital appreciation. For
the first six months of 1998, the Series provided a total return of (12.62)%.
Over the same period, the Standard and Poors 500 Index and Russell 2000 Index
had total returns of 17.71% and 4.93%, respectively.

Performance was unexpectedly difficult during the first half of the year as
concerns over a slowing global economy pressured all hard asset securities. The
Goldman Sachs Commodity Index fell 18.3%, the Morgan Stanley Real Estate Index
fell 5.1%, and gold shares fell 3.6% (MSCI World Gold Mines Index). Finally, the
Morgan Stanley Commodity-Related Equity Index (an index of natural resource
companies) fell 5.7% during the first half of the year.

Hard asset markets have recognized these difficult trading conditions as most
commodity markets fell significantly. The Series had hedged some oil and metals
exposure during this period and was able to profit from this, but allocations to
resource shares (40-50% of the portfolio) proved to be too high. Oil prices fell
about 20% during the first half of the year and industrial metals prices fell
about 12% due primarily to decreased demand from Asia. Moreover, supply
additions in many markets continued, putting further pressure on prices.

In contrast to difficult conditions in other markets, we thought that real
estate offered strong underlying fundamentals and defensive characteristics.
Therefore, we allocated one-third of the portfolio to this sector. However, real
estate securities in the United States experienced difficult markets for several
reasons. These reasons included investor assumptions that real estate prices had
peaked, that legislative changes would alter the Real Estate Investment Trust
(REIT) structure and dampen investor enthusiasm, and that additions to supply
would bring prices crashing down. Our analysis suggests that these factors are
temporary or incorrect, and that exceptional value can be found in real estate
securities. We continue to like real estate and have approximately 40% of the
Series allocated to this sector.

While the energy sector has suffered from declining demand from Asia, a warm
winter in the Northern Hemisphere, and increased production, we think oil prices
are near a bottom. The recently announced OPEC production cuts are enough to
swing the market into a deficit situation in the fourth quarter and bring
inventories down to a level that has historically resulted in higher trading
ranges than current forward prices. Recent discussions regarding a "new
alliance" of oil producers who control 70% of the world's known oil reserves and
almost two-thirds of all oil exports will also serve to increase uncertainty and
put a floor under prices. Their goal is to boost oil prices by more than 50%.

Gold has been in a tight trading range ($280-$310) throughout most of the year
as most of the negatives appear to have been factored into prices last year. We
anticipate that this trading range will continue for the remainder of the year.
Therefore, we will maintain our policy of buying when prices fall below this
range.

While global economic conditions are likely to remain difficult, we believe hard
asset securities have already priced this in. The time to increase allocations
to asset classes such as hard assets is near cyclical lows when valuations are
at trough levels. We believe commodity prices are near or at lows, particularly
oil. In addition, valuations on many other securities are at levels which have
only existed in recessionary conditions.

                               REAL ESTATE SERIES
 
The Real Estate Series (the "Series") seeks capital appreciation and
secondarily, current income. During the first six months of 1998, the Series had
a total return of (4.11)%. The Wilshire Real Estate Securities Index had a total
return of (5.31)% over the same period.

Real estate securities underperformed the market in the first half of 1998 due
to several reasons. There was excessive publicity surrounding the modification
of Real Estate Investment Trust (REIT) tax legislation. This cast a pall on the
entire industry, when in fact, the Portfolio Manager believes that the true
economic impact will be minimal and will effect only five companies. The issue
will be settled with the expected passage of the IRS legislation in July, 1998.

The stock market had been stronger than expected, reacting to the unexpected
stimulative effects of the Asian economic crisis on U.S. domestic consumption.
Real estate securities are viewed as defensive securities in the context of the
overall market. So, in strong markets, aggressive investors sell real estate
securities to purchase more volatile issues.

Real estate prices have risen as occupancy rates have increased. In many
instances, development is again justified. REITs are therefore finding increased
competition to finance this resurgence of development. The reemergence of
development also resurrects fears of the overdevelopment which created
oversupply problems in the late 1980's.

Beginning last year, the Portfolio Manager anticipated that acquisition
opportunities would be reduced in 1998 and 1999, and that emphasis should be
placed on companies with strong internal growth. As a result, the portfolio was
rebalanced in the first quarter.

Reflecting the strength in domestic consumer spending, the Series' weighting in
the retail sector was increased. This included increasing the position in Kimco
Realty Corporation, one of the largest strip center REITs. Kimco Realty
Corporation has been one of the best performing holdings in 1998 with a total
return of over 19% year-to-date.

Out of concern for weakness in export markets due to the Asian crisis, the
Series reduced the overweighting of the industrial sector. The Portfolio Manager
continues to question the prospects for the storage sector, so he has reduced
positions in Storage (USA) Inc.

The portfolio weightings in Manhattan and surrounding areas were increased with
additional purchases of Reckson Associates Realty Corporation, S.L. Green Realty
Corporation, and Vornado Realty Trust. This market continues to be protected by
one of the most restricted development environments, and prices remain below
replacement cost. To increase the exposure to development opportunities,
particularly in California, the Portfolio Manager doubled the position in
Catellus Development Corporation.

The objective of the Market Manager Series (the "Series") is to seek favorable
equity market performance and at the same time preserve capital.

For the first half of 1998, the total return of the Series was 13.6%. Over the
same period, the Standard & Poors 500 Index had a total return of 17.71%, and
the Russell Midcap Index had a total return of 9.13%.

The Series began operations on November 14, 1994. At that time, all funds were
invested in short-term money market securities. On March 6, 1995, the Series was
closed to further investment and the Portfolio Manager began investing in
accordance with the long-term investment objectives of the Series.

The Series contains a blend of debt securities and over-the-counter equity
options. The equity options allow the Portfolio to track the performance of the
equity markets. The debt securities provide some degree of capital protection.

Since March 1995, Portfolio returns have been very similar to the returns of the
Standard & Poors 500 Index and Russell Midcap Index.

                           MULTIPLE ALLOCATION SERIES
 
The Multiple Allocation Series (the "Series") seeks the highest total return,
consisting of capital appreciation and current income, consistent with the
preservation of capital.

For the six months ended June 30, 1998, the Series returned 4.97%. Over the same
period, the Standard & Poors 500 Index ("S&P 500") had a total return of 17.71%
and the Lehman Brothers Intermediate Government/Corporate Bond Index ("Lehman
Index") had a total return of 3.47%. The benchmark for this Portfolio (40% S&P
500, 60% Lehman Index) was 9.07% for the six months of 1998.

The underperformance of the Series was due to the significant divergence between
growth and value stocks. The Series' strategy focuses on low P/E, high dividend,
value oriented stocks. In 1998, large-cap, more volatile, growth stocks have
been leading the equity markets higher.

On the positive side, we took an aggressive stance on the bond market. With a
duration longer than the benchmark, the Series experienced positive returns as
the yield on the 30-year Treasury fell from 5.92% at the end of 1997 to 5.62% as
of June 30, 1998.

Automobile stocks continued to contribute positive returns. Most notably, Ford
Motor Company and Chrysler Corporation have managed to do exceptionally well so
far in 1998. Ford Motor Company is well positioned as a global leader and
Chrysler Corporation expanded its horizons with the announcement of its merger
with Daimler-Benz. General Motors Corporation is mired in a strike but has
managed to hold up reasonably well pending the outcome.

Other groups that have shown solid performance are the financials, retailers and
technology stocks. Some of the Series' top financial holdings are Morgan
Stanley, Dean Witter Discover and Company and Paine Webber Group Inc. With the
retailers, Ross Stores Inc. and Fingerhut have been steadily outperforming.

Dell Computer Corporation and Microsoft Corporation continue to be remarkable
market leaders in technology. The low interest rate environment and the healthy
stock market continue to fuel the performance of these companies.

The industry groups that have been the most disappointing thus far in 1998 are
linked mainly to commodities. These include oils, metals, papers and chemicals.

In particular, oils and metals have been hurt by the diminished demand out of
Asia causing significant weakness in their prices. However, these stocks
continue to rank well based on a value perspective and any firmness in commodity
prices should help the stock prices of these companies.

We will continue to keep a close eye on the Asian situation and evaluate the
portfolio's investments accordingly.

                              FULLY MANAGED SERIES
 
The Fully Managed Series (the "Series") seeks, over the long term, a high total
investment return, consistent with the preservation of capital and prudent
investment risk. For the first six months of 1998, the Series provided a return
of 5.59%.

Over the same time period, the Standard & Poors 500 Index ("S&P 500") had a
total return of 17.71%, and the Lehman Brothers Government/Corporate Bond Index
("Lehman") had a total return of 4.17%. The benchmark for this portfolio (60%
S&P 500, 40% Lehman) was 12.22% for the first six months of 1998.

With interest rates lower, the portfolio's fixed income securities and related
holdings had good results. On the equity portion of the portfolio, the Series
could not match the amazing strength of the broad equity market indices. This
was due in part to the portfolio's conservative structure.

The Series' basic asset allocation among equities, convertibles, bonds,
preferred stock, and reserves changed little these past six months. However,
several changes were made within the first two categories.

The largest purchases were Times Mirror Company convertible bonds and Niagara
Mohawk Power Corporation common stock. These new positions now represent two of
the largest holdings.

Electric utility holdings did particularly well considering the lackluster
recent returns achieved by most investors in this group.

Media holdings, including New York Times Company, Washington Post Company, and
Time Warner Inc., continued to perform well. The Series established positions in
this group during periods of uncertainty and then reaped the benefits of renewed
investor enthusiasm and solid corporate growth.

Most of the poor performers were in the natural resources area. While the
Portfolio Manager retains confidence in the individual companies, he was
disappointed that the industry picture turned so negative.

At the very least, a normalization of the current negative sentiment should
provide reasonable returns going forward. Beyond that, the Portfolio Manager can
envision various market conditions that could generate substantial returns for
gold stocks when the rest of the market is faltering.

Looking forward, we believe that high valuations and suspect corporate reporting
dramatically lower the odds of successfully investing in equities. However, the
Series will continue to maintain a 50% weighting in common stocks and an
increased exposure in convertibles.

In one of history's most rewarding investing climates, we believe that the
Series has invested in securities that should capture a good portion of the
returns enjoyed by more aggressive investors while maintaining a lower level of
volatility.

                          LIMITED MATURITY BOND SERIES

The Limited Maturity Bond Series (the "Series") seeks to obtain the highest
current income that is consistent with low risk to principal and liquidity. For
the first six months of 1998, the Series provided a total return of 3.10%. The
Merrill Lynch 1-5 Year Corporate/Government Bond Index (the "benchmark") had a
total return of 3.24% over the same period.

In the first half of the year, the economy continued to exhibit impressive
forward momentum. Strong consumer demand, increases in construction activity and
a rebound in business capital spending have led to concerns about rising
inflation. Although the Federal Reserve Board (the "Fed") shares these concerns,
conditions in Asia have prevented them from increasing the discount rate.

The economic crisis in Asia had a profound impact on financial markets during
the first half of the year. In the United States, yields on U.S. Treasury
securities declined 0.15% to 0.30% across the yield curve. This helped the
performance of fixed income portfolios, because lower yields translate into
higher bond prices.

Credit spreads increased during the period. In other words, yields on securities
with lower credit ratings declined less than higher-rated securities. In this
environment, securities with higher credit ratings tend to produce higher
returns.

During the first half of the year, the Series had more credit risk than the
benchmark. This was the primary reason that Series returns trailed the
benchmark.

In all other respects, the portfolio was very similar to the benchmark.
Throughout the period, the Series had an average maturity and effective duration
(i.e. interest rate sensitivity) that were very similar to the benchmark.

Looking forward, the Portfolio Manager expects interest rates to remain stable,
or possibly decline. Renewed turmoil in Asia, coupled with a sizable inventory
retrenchment should lead to a slowdown in the U.S. growth rate. This would allow
the Fed to keep the discount rate at its current level.

The Portfolio Manager also expects credit spreads to remain stable, or possibly
decline. He believes that credit spreads already reflect any potential problem
in the market.

Given this outlook, the Portfolio Manager plans to extend the effective duration
and increase the credit risk of the portfolio. These strategies will enhance
returns if interest rates and credit spreads decrease or remain stable.

The Portfolio Manager also plans to re-enter the mortgage-backed securities
market. In his opinion, yields on these securities are finally reflecting an
appropriate amount of prepayment risk.

                              LIQUID ASSET SERIES

The objective of the Liquid Asset Series (the "Series") is a high level of
current income, consistent with the preservation of capital and liquidity. The
Series had a total return of 2.55% for the first six months of 1998.

Over the past six months, there have been many conflicting signals regarding the
direction of interest rates. This has created interesting challenges for money
market managers.

In the first week of January, short-term interest rates declined by
approximately 0.25%. This occurred because investors thought the Asian financial
crisis would cause the U.S. economy to slow down. They expected the Federal
Reserve Board (the "Fed") to maintain or lower the discount rate.

During the first quarter, economic growth appeared to be much stronger than
expected. Many investors feared the Fed would increase the discount rate, and
short-term interest rates increased by more than 0.30% in late-January and
February.

At its meeting in March, the Fed signaled a bias toward increasing the discount
rate. However, they said that continuing financial problems in Asia have kept
them from doing so.

Since the beginning of March, short-term interest rates have been very stable.
They have varied within a 0.10% to 0.15% range, as investors reacted to the
latest information about the economy, inflation, or the financial crisis in
Asia.

At the beginning of the year, the Series had an average maturity of
approximately 45 days. For a short time, the Portfolio Manager extended the
average maturity of the portfolio. However, this strategy was reversed as
interest rates appeared to be heading upward.

For most of the six-month period, the Portfolio Manager has been reducing the
average maturity. He thought this strategy was prudent, given the uncertain
interest rate environment. At the end of June, the Series had an average
maturity of approximately 35 days.

During the second half of 1998, the Portfolio Manager expects short-term
interest rates to decline. There is renewed turmoil in Asia, and many U.S.
companies are working to reduce their inventory levels. These forces should slow
economic growth and keep inflation in check.

The Portfolio Manager plans to extend the average maturity of the portfolio.
This will position the Series for a stable or declining interest rate
environment.

This strategy may be changed if conditions warrant. The Series holds highly
liquid instruments, and this provides the Portfolio Manager with flexibility to
respond to changes in the economic environment.

                                 THE GCG TRUST
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
The GCG Trust, (the "Trust") is registered under the Investment Company Act of
1940 as an open-end management investment company. The Trust was organized as a
Massachusetts business trust on August 3, 1988 with an unlimited number of
shares of beneficial interest with a par value of $0.001 each. At June 30, 1998
the Trust had eighteen operational portfolios (the "Series"): Small Cap Series
("SC"), All-Growth Series ("AG"), Capital Appreciation Series ("CA"), Value
Equity Series ("VE"), Rising Dividends Series ("RD"), Strategic Equity Series
("SE"), Growth Opportunities Series ("GO"), Managed Global Series ("MG"),
Emerging Markets Series ("EM"), Developing World Series ("DW"), Hard Assets
Series ("HA"), Real Estate Series ("RE"), Market Manager Series ("MM"), Multiple
Allocation Series ("MA"), Fully Managed Series ("FM"), Limited Maturity Bond
Series ("LMB"), Liquid Asset Series ("LA") and The Fund For Life Series. All of
the Series are diversified except for HA, MG and MM which are non-diversified
Series. The information presented in these financial statements pertains to all
of the Series except for The Fund For Life Series which is presented under
separate cover. The Trust is intended to serve as an investment medium for (i)
variable life insurance policies and variable annuity contracts ("Variable
Contracts") offered by insurance companies, and (ii) certain qualified pension
and retirement plans, as permitted under the Federal tax rules relating to the
Series serving as investment mediums for Variable Contracts. The Trust currently
functions as an investment medium for contracts and policies offered by Golden
American Life Insurance Company ("Golden American"), a wholly owned subsidiary
of Equitable of Iowa Companies ("Equitable of Iowa"), an indirect wholly owned
subsidiary of ING Groep, N.V. ("ING") and affiliated insurance companies. The
Trust is also an investment medium for contracts offered by the Mutual Benefit
Life Insurance Company in Rehabilitation and by the Security Equity Life
Insurance Company.
 
All of the Series commenced operations on January 24, 1989, except for CA which
commenced operations on May 4, 1992, MG which commenced operations on October
21, 1992, RD and EM which commenced operations on October 4, 1993, MM which
commenced operations on November 14, 1994, VE which commenced operations on
January 3, 1995, SE which commenced operations on October 2, 1995, SC which
commenced operations on January 3, 1996, GO and DW which commenced operations on
February 18, 1998.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Trust in the
preparation of its financial statements. The policies are in conformity with
generally accepted accounting principles.
 
(A) VALUATION: Domestic and foreign portfolio securities including options and
futures contracts, except as noted below, for which market quotations are
readily available are stated at market value. Market value is determined on the
basis of the last reported sales price in the principal market where such
securities are traded or, if no sales are reported, the mean between
representative bid and asked quotations obtained from a quotation reporting
system or from established market makers or dealers.
 
Debt securities (except those purchased by LA), including those to be purchased
under firm commitment agreements, are normally valued on the basis of quotes
obtained from brokers and dealers or pricing services, which take into account
appropriate factors such as institutional-size trading in similar groups of
securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics, and other market data. Under certain circumstances, debt
securities having a maturity of sixty days or less may be valued at amortized
cost which approximates market value.
 
Amortized cost involves valuing a portfolio security instrument at its cost,
initially, and thereafter, assuming a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of the instrument. All of the portfolio securities of LA are
valued using the amortized cost method.
 
Securities for which market quotations are not readily available are valued at
fair value as determined in good faith by, or under the direction of, the Board
of Trustees.
 
(B) DERIVATIVE FINANCIAL INSTRUMENTS: Certain of the Series may engage in
various portfolio strategies, as described below, primarily to seek to manage
its exposure to the equity, bond, gold and other markets and also to manage
fluctuations in interest and foreign currency rates. Buying futures and forward
foreign exchange contracts, writing puts and buying calls tend to increase a
Series' exposure to the underlying market or currency. Selling futures and
forward foreign exchange contracts, buying puts and writing calls tend to
decrease a Series' exposure to the underlying market or currency. In some
instances, investments in derivative financial instruments may involve, to
varying degrees, elements of market risk and risks in excess of the amount
recognized in the Statement of Assets and Liabilities. Losses may arise under
these contracts due to the existence of an illiquid secondary market for the
contracts, or if the counterparty does not perform under the contract. An
additional primary risk associated with the use of certain of these contracts
may be caused by an

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
imperfect correlation between movements in the price of the derivative financial
instruments and the price of the underlying securities, indices or currency.
 
OPTIONS: Certain Series may engage in option transactions including purchasing
options on securities and securities indices ("purchased options") and writing
covered call and secured put options ("written options"). Generally, purchased
options are utilized to protect security holdings in a portfolio or protect
against substantial increases in market prices in securities to be acquired in
the future. MM invests in purchased options on security indices in accordance
with its long term investment objectives to obtain equity market performance.
Certain Series may use written options to generate additional income, protect
partially against declines in the value of portfolio securities or facilitate a
Series' ability to purchase a security at a price lower than the security's
current market price. Option transactions may be engaged in on exchanges and on
over-the-counter markets. When a Series writes an option, an amount equal to the
premium received by the Series is reflected as an asset and an equivalent
liability. The amount of the liability is subsequently marked to market on a
daily basis to reflect the current value of the option written. When a security
is sold through an exercise of an option, the related premium received (or paid)
is deducted from (or added to) the basis of the security sold. When an option
expires (or the Series enters into a closing transaction), the Series realizes a
gain or loss on the option to the extent of the premiums received or paid.
Realized and unrealized gains and losses arising from purchased option
transactions are included in the net realized and unrealized gain/(loss) on
securities.

FUTURES CONTRACTS: Certain Series may engage in various futures contracts
including interest rate and stock index futures contracts. The transactions in
futures contracts must constitute bona fide hedging or other strategies under
regulations promulgated by the Commodities Futures Trading Commission. Upon
entering into a contract, the Series deposits and maintains as collateral such
initial margin as required by the exchange on which the transaction is effected.
Pursuant to the contract, the Series agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in value of the contract. Such
receipts or payments are known as variation margin and are recorded by the
Series as unrealized gains or losses. When the contract is closed, the Series
records a realized gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was closed.
During the six months ended June 30, 1998, all futures transactions were
conducted on U.S. exchanges. Contracts open, if any, at June 30, 1998 are
included in the portfolio of investments and their related realized and
unrealized gains and losses are included in the net realized and unrealized
gain/(loss) on futures contracts.
 
FORWARD FOREIGN EXCHANGE CONTRACTS: Certain of the Series may enter into forward
foreign exchange contracts. A Series will engage in forward foreign exchange
currency transactions to protect itself against fluctuations in currency
exchange rates. Forward foreign exchange contracts are valued at the applicable
forward rate and are marked to market daily. The change in market value is
recorded by the Series as an unrealized gain or loss. When the contract is
closed, the Series records a realized gain or loss equal to the difference
between the value of the contract at the time it was opened and the value at the
time it was closed. Contracts open, if any, at June 30,

                                 THE GCG TRUST
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
1998 and their related unrealized appreciation/(depreciation) are set forth in
the Schedule of Forward Foreign Exchange Contracts which accompanies the
Portfolio of Investments. Realized and unrealized gains and losses arising from
forward foreign exchange contracts are included in net realized and unrealized
gain/(loss) on forward foreign exchange contracts.
 
SECURITIES SOLD SHORT: AG is engaged in selling securities short, which
obligates the Series to replace a security borrowed by purchasing the same
security at the current market value. The Series would incur a loss if the price
of the security increases between the date of the short sale and the date on
which the Series replaces the borrowed security. The Series would realize a gain
if the price of the security declines between those dates.
 
(C) FOREIGN CURRENCY: Assets and liabilities denominated in foreign currencies
and commitments under forward foreign currency exchange contracts are translated
into U.S. dollars at the mean of the quoted bid and asked prices of such
currencies against the U.S. dollar as of the close of business immediately
preceding the time of valuation. Purchases and sales of portfolio securities are
translated at the rate of exchange prevailing when such securities were acquired
or sold. Income and expenses are translated at the rate of exchange prevailing
when accrued.
 
The Trust does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on securities from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain/(loss) from securities.
 
Reported net realized gains or losses on foreign currency transactions arise
from sales and maturities of short-term securities, sales of foreign currencies,
currency gains or losses realized between the trade and settlement dates on
securities transactions, the difference between the amounts of dividends,
interest, and foreign withholding taxes recorded on the Series' books, and the
U.S. dollar equivalent of the amounts actually received or paid. Net unrealized
appreciation/(depreciation) on other assets and liabilities denominated in
foreign currencies arise from changes in the value of assets and liabilities
other than investments in securities at period end, resulting from changes in
the exchange rate.
 
(D) REPURCHASE AGREEMENTS: All Series may enter into repurchase agreements in
accordance with guidelines approved by the Board of Trustees of the Trust. Each
Series bears a risk of loss in the event that the other party to a repurchase
agreement defaults on its obligations and the Series is delayed or prevented
from exercising its rights to dispose of the underlying securities received as
collateral including the risk of a possible decline in the value of the
underlying securities during the period while the Series seeks to exercise its
rights. Each Series takes possession of the collateral and reviews the value of
the collateral and the creditworthiness of those banks and dealers with which
the Series enters into repurchase agreements to evaluate potential risks. The
market value of the underlying securities received as collateral must be at
least equal to the total amount of the repurchase obligation. In the event of
counterparty default, the Series has the right to use the underlying securities
to offset the loss.
 
(E) FEDERAL INCOME TAXES: Each Series of the Trust is a separate entity for
Federal income tax purposes. No provision for Federal income taxes has been made
since each Series of the Trust has complied and intends to continue to comply
with provisions of subchapter M of the Internal Revenue Code of 1986, as
amended, available to regulated investment companies and to distribute its
taxable income to shareholders sufficient to relieve it from all or
substantially all Federal income taxes.
 
(F) SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Investment transactions are
recorded on trade date. Dividend income and distributions to shareholders are
recorded on the ex-dividend date, except certain dividends from foreign
securities where the ex-dividend date may have passed are reported as income
when the Series identifies the dividend. Interest income (including amortization
of premium and discount on securities) and expenses are accrued daily. Realized
gains and losses from investment transactions are recorded on an identified cost
basis which is the same basis the Trust uses for Federal income tax purposes.
Purchases of securities under agreements to resell are carried at cost, and the
related accrued interest is included in interest receivable.
 
(G) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS: Net investment income of LA is
declared as a dividend daily and paid monthly. For all other Series, net
investment income will be paid annually, except that LMB may declare a dividend
monthly or quarterly. Any net realized long-term capital gains (the excess of
net long-term capital gains over net short-term capital losses) for any Series
will be declared and paid at least once annually. Net realized short-term
capital gains may be declared and paid more frequently. Income distributions and
capital gain distributions are determined in accordance with income tax
regulations which may differ from net investment income and net realized gains
recorded by the Trust. These differences are primarily due to differing
treatments of income

as a whole.
 
2.  FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 
Directed Services, Inc. (the "Manager"), a wholly owned subsidiary of ING,
provides all of the Series with advisory and administrative services under a
Management Agreement (the "Agreement"), for which the Manager is compensated
under a different arrangement. Under the Agreement, the Manager has overall
responsibility for engaging Portfolio Managers and for monitoring and evaluating
the management of the assets of each Series by the Portfolio Managers. Portfolio
Managers are compensated by the Manager and not the Trust. In some cases,
Portfolio Managers may be affiliated with the Manager. Portfolio Managers have
full investment discretion and make all determinations with respect to the
investment of a Series' assets and the purchase and sale of portfolio securities
and other investments. Pursuant to this Agreement, the Manager also is
responsible for providing or procuring, at the Manager's expense, the services
reasonably necessary for the ordinary operation of the Trust including, among
other things, custodial, administrative, transfer agency, portfolio accounting,
dividend disbursing, auditing and ordinary legal services. The Manager does not
bear the expense of brokerage fees, taxes, interest, fees and expenses of the
independent trustees, and extraordinary expenses, such as litigation or
indemnification expenses. As compensation for its services under the Management
Agreement, the Trust pays the Manager a monthly fee (a "Unified Fee") based on
the following annual rates of the average daily net assets of the Series:
