February 20, 1998

Dear First Variable Contract Holder,

I am pleased to present the annual report for the Variable Investors Series
Trust (VIST). These portfolios are the investments within your First Variable
contract.

We've designed a new look for the report that makes it easier for you to find
important information on the portfolios. Inside, you'll find a short list of the
top ten holdings and key information. Each and every holding of the portfolio
and other financial information is shown later in the report. Take a moment to
familiarize yourself with the new format. I think you'll like it as much as I
do.

Again in 1997, the stock market performed well. The S&P 500, one of the most
popular market measures, was up 33.4% over the course of the year. Despite the
exuberance of this market indicator, many other investment categories did not
fare as well. In fact, the top 50 performing stocks of the S&P 500 Index
accounted for nearly two-thirds of its return. These 50 companies are quite
large and make up only a small portion of the total market. Most of our
portfolios seek investment results from several other types of investments, such
as small to mid-sized companies.

The bond market, as measured by the Salomon Broad Investment Grade Bond Index,
returned 9.6% during 1997. The high yield market did particularly well this year
and returned 12.63%, as measured by the First Boston High Yield Index. While
these returns are less than the stock market, they are very good for the bond
markets.

While the markets performed well this year, this may not always be the case in
the future. I ask you to remember that your investment in First Variable's
products is part of your long-term plan. Your financial adviser can help you
adjust your plan as your life situations and financial goals change.

Your investment choices are very important as you build, enjoy and preserve your
wealth. At First Variable, we are committed to offering you the products,
services and information you need to shape your financial future.

                                    Regards,


                                    /s/ John M. Soukup

Small Cap Growth Portfolio

Objective

Seeks capital appreciation by investing primarily in common stocks of emerging
companies with the potential for significant capital appreciation and strong
earnings growth with attendant risk. The Portfolio normally invests at least 65%
of assets in common stocks and convertible securities issued by companies with
market capitalization or annual revenues not exceeding $1 billion at the time of
purchase.

Management's
  Discussion & Analysis

The past year will go down in the record books as rather moody and certainly
volatile. Small and mid-cap growth stocks suffered substantial underperformance
in 1997, as the rally from late April through early October was preceded and
followed by severe corrections. For the year, the Portfolio returned 0.73%,
compared to the Russell 2000 Index which returned 22.37%.

PERFORMANCE

In the first quarter, fears of excessive economic strength and higher interest
rates caused stock prices to weaken and precipitated a correction in the market.
Small cap stocks with high earnings growth rates and high P/E ratios were
hardest hit, as investor favor turned toward the perceived safety of larger,
more liquid names. This investment climate was particularly difficult for our
disciplined approach because we invest in companies with the highest sustainable
earnings growth.

By the end of April, the market tide and investor sentiment had shifted, causing
growth and small cap shares to climb once again. The tone changed again from
July through September. Equity results were mixed as inflation fears and worry
over a Fed rate hike resurfaced. Large cap stocks gave back a portion of their
earlier gains, but small cap issues and technology stocks barely broke stride.

In October, Asia roiled the world's markets with a currency crisis. The Asian
turmoil sparked the year's second correction in smaller cap growth stocks.
Although the crisis is likely to have a more pronounced long term impact on the

Management's
  Discussion & Analysis (CONTINUED)

bottom line of global, large cap companies than small cap shares, investors
shunned the less liquid small caps and prices dropped sharply.

OUTLOOK

In our opinion, the revised outlook for slower corporate earnings growth due to
the financial crisis in Asia actually improves the outlook for small cap stocks,
which generally derive a smaller proportion of their revenues from abroad. The
gains can be spectacular over time, but owing to the limited liquidity of small
cap growth stocks, moves are often powerful, brief and irregular.

The backdrop for our style of investing is very favorable in our view: low
relative valuations, a slowing trend in profit growth for many large cap names,
a favorable tax rate on capital gains, and a benign interest rate environment.
Many of the stocks we own have solid fundamentals but have been indiscriminately
punished as investor fear has driven investors to more liquid stocks and
alternative financial assets.

Looking ahead, we are prepared for continued volatility in 1998. We have
confidence in the companies we own and in the investment strategies that have
proven successful for us over the years.

"Total Return" is calculated including reinvestment of all income dividends and
capital gain distributions. Results represent past performance and do not
indicate future results. The value of an investment in the Small Cap Growth
Portfolio and the return on the investment both will fluctuate and redemption
proceeds may be higher or lower than an investor's original cost.

** Performance data is historical and includes changes in share price and
reinvestment of dividends and capital gains. Performance numbers are net of
all operating expenses, but do not include any insurance charges imposed in
connection with your variable insurance contract. If this performance
information included the effect of the insurance charges, performance numbers
would be lower.

World Equity Portfolio

Objective

The investment objective of the World Equity Portfolio is to seek maximum
long-term total return by investing primarily in common stocks, and securities
convertible into common stocks, traded in securities markets located around the
world, including the United States. This objective per First Variable's
instruction, is to be obtained via international "blue chips" and domestic U.S.
small cap stocks.

Management's
  Discussion & Analysis

Volatility was the major theme of the third and fourth quarters in 1997. The
currency, stock market and economic problems that began in Thailand and
Indonesia this summer, spread concern and uncertainty throughout the remainder
of Asia and caused tremors in all global markets.

PORTFOLIO PERFORMANCE

Fortunately for the international component of this portfolio, our exposure to
the problems in Asia was kept to a minimum due to our underweight position in
the region throughout the year. European markets provided the best investment
environment. Three of our top four performing markets were our European stocks
in Italy (37.1%), the Netherlands (29.8%), and the United Kingdom (15.6%).
Disappointing performers for us were our selections in Australia, Brazil,
Finland, and Japan. Additionally, a strengthening U.S. dollar worked to dilute
local performance. Our proactive currency management enabled us to partially
protect local returns versus a strong U.S. dollar. We partially hedged our
currency exposure with the use of forward contracts. For the year, the Portfolio
returned 9.98% compared to 15.76% for the MSCI World Index.

On the domestic side, an overweight position in U.S. technology stocks and a
generally poor market for most U.S. small cap stocks hurt the performance in the
first quarter of 1997 and proved to be a drag on the overall performance of this
portion of the portfolio for the year. The significant event in the fourth
quarter was the turmoil in many Asian countries. Many of the

Management's
  Discussion & Analysis (Continued)

U.S. companies in the portfolio do manufacture and market overseas.
Semiconductor stocks and electronic technology, the sector with the most Asian
exposure, significantly underperformed losing nearly 25%. We believe the market
is cutting the valuations of these companies indiscriminately; therefore we
believe there are good opportunities in the higher quality companies. The
financial sector continued its strong performance in the fourth quarter, and
telecommunications service stocks also provided above average returns.

OUTLOOK

On the international side, we continue to be most optimistic about Europe. Most
European markets continue to benefit from low inflation, low relative interest
rates, slow but improving growth, strong bond markets, cost cutting and
corporate restructuring as the continent moves toward the European Monetary
Union in 1999. Asia is being watched very closely. We expect volatility in these
markets to continue as they come to grips with the implications of the massive
devaluations their currencies have suffered and the restructuring their
economies have to undergo. We are additionally monitoring Japan as its financial
system is restructured and it awaits the outcome facing the rest of Asia.

Domestically, we believe economic conditions of moderate growth with flat to
declining interest rates are favorable for small cap companies. The volatility
provides us the opportunity to take positions in high quality companies at
attractive valuation levels. Small cap stocks tend to move significantly in
short periods of time. Our focus is on areas with little cyclical sensitivities
and sustainable earnings growth.

Growth Portfolio

Objective

Seeks capital growth by investing primarily in common stocks and securities
convertible into common stock. Also seeks current income when consistent with
the primary objective. Securities are selected on the basis of their issuers'
long-term potential for expanding their earnings, profitability, and size and on
the basis of potential increases in market recognition of their securities.

Management's
  Discussion & Analysis

With continued strength in the U.S. economy, benign inflation, better than
expected corporate profit growth, and strong cash flows into equities and equity
products, 1997 was again a profitable year for the stock market, with the S&P
500 up 33.4% on a total return basis. This marked the third straight year in
which the market had advanced more than 20%, an occurrence never before seen.
However, the year ended on a sour note as the confluence of political, economic
and currency woes in Southeast Asia during the fourth quarter reverberated
throughout the world with repercussions that are still unknown. The economies of
the former Asian tigers have slowed dramatically and their equity markets have
been pummeled. The U.S. market dropped 554 points on one day in late October and
has been chained to an Asian-driven roller coaster ever since. In a dramatic
flight to quality, investors have poured money into U.S. Treasuries and the
yield on the long bond plunged to a recent low of 5.7% from about 6.6% in
October. Investors fear that Asia will attempt to export its deflation to the
U.S. The Federal Reserve decided to leave monetary policy unchanged at the
November and December Federal Open Market Committee meetings. We do not believe
the Fed will run the risk of potentially exacerbating a global economic crisis
by raising interest rates. In fact, the Fed may be shifting to a bias of
lowering interest rates.

PORTFOLIO PERFORMANCE

The Growth Portfolio had a total return (including dividends and income) for
1997 of 23.6% as compared to 33.4% for the S&P 500 Index. Stock selection is
guided by the Value Line Timeliness Ranking which focuses on

  Discussion & Analysis (CONTINUED)

stocks with superior earnings growth and price momentum. The Ranking System is
heavily weighted in mid-cap and small-cap stocks which lagged the large
capitalization stocks such as those in the S&P 500 for the year. In addition,
the portfolio was overweighted in both the technology and energy sectors, both
of which suffered retrenchment at the end of the year due to concerns about
their exposure to the Asian meltdown. Growth stocks, in general, ended 1997
poorly as investors feared the Asian crisis would severely impact earnings
growth. The third area of overweighting, financial services, proved beneficial,
as these stocks benefited from the decline in interest rates at the end of the
year.


OUTLOOK

For 1998 we have a cautious outlook for the stock market, although we do believe
a high single digit or low double digit return is possible from current levels.
However, we would expect ongoing volatility as news from Asia alternates between
good and bad. We expect to remain overweighted in technology, a true growth
area, with a primary focus on software stocks with limited exposure to Asia.
Financials will also continue to see heavy overweighting as will health care.
Both sectors are primarily U.S. based and not expected to suffer significantly
from problems in Asia. Utilities and consumer staples will remain underweighted,
due to poor earnings growth and a lack of pricing power.

Matrix Equity Portfolio

Objective

Seeks capital appreciation and current income by investing in a diversified
portfolio of equity securities that is selected on the basis of a proprietary
analytical model.

Management's
  Discussion & Analysis

Most of the Matrix and market performance came in the second and third quarters
of the year, which combined to produce a return of 30%. For the balance of the
year the Portfolio benefited greatly from its consistent overweight to the
technology and consumer retail sectors, as several core holdings performed
extremely well. These included computer makers Dell Computer (200% for the year)
and Compaq Computer (90%), and software firms Compuware Corp. (140%) and
Computer Associates (60%). In addition the fund had a significant stake in
well-known firms such as drug company Bristol-Myers Squibb (70%), BankAmerica
Corp. (50%), and department store retailer Dayton-Hudson Corp. (70%). Our
successful concentration on those stocks that offer both good value as well as
improving earnings growth was important, as many of these firms demonstrated
consistently positive earnings surprises, causing investors to re-value these
stocks at significantly higher prices. For the year, the Portfolio returned
22.05%, compared to 33.4% for the S&P 500 Index.

Consistent with the theme of growth versus value investing, the Matrix growth
model outperformed our value model for most of the year. Until the final two
months, when neither model performed particularly well, our estimate revision
model had been remarkably consistent in separating the winners from losers
during each month of 1997. Much of the Matrix outperformance during the year was
therefore attributable to our growth model - though our value model was
instrumental during our strong third quarter when many of the
largest-capitalization stocks (e.g. most over-valued) corrected sharply. Also,
as is often overlooked, the measure of a good valuation process is found in
keeping a portfolio away from those stocks that are most at risk, as well as in
finding attractive candidates for

buying. By this measure our value model also acquitted itself reasonably well in
1997.


The Portfolio is currently somewhat overweight in financial and consumer retail
shares, where several firms remain under-valued relative to their strong
earnings expectations. The Portfolio is no longer heavily weighted towards
technology stocks, though since many computer stocks have now corrected sharply
we may yet see a few compelling valuations in this sector. The Portfolio
continues to be underweight to the basic materials sector (chemicals, paper, and
metal stocks), as depressed commodity prices are weakening the profit outlooks
of many of these firms. In addition, several of the very largest consumer
staples stocks such as Coca-Cola, PepsiCo., and Walt Disney remain unattractive
due to their high price multiples (30-40 times 1998 earnings forecasts) and
unspectacular rates of profit growth. The Portfolio has remained consistently
underweight to the consumer staples sector as a result.

The Matrix strategy will continue to invest in those stocks that appear
undervalued relative to improving earnings prospects, and stay well-diversified
and balanced with respect to the S&P 500 Index. As the U.S. market will not
continue to return 20% indefinitely, it is now especially important to remain
well diversified and mindful of valuations. The American economy is expected to
continue to grow real GDP at a commendable rate of 2.5-3.0% in 1998, with
continued low inflation. However, much of the economic performance will depend
on the recent Asian weakness remaining contained, and not spreading to the
western economies. If European and North American economies can continue to
generate steady economic performance while Japanese and Asian banks sort out
their capital troubles, then financial asset performance can remain reasonably
positive over the next 12 months. If not, then the threat of price deflation
and/or recession may become real, with obvious consequences for corporate
profits and financial asset prices.

Most expectations for 1998 now place S&P 500 earnings growth at 6-8%, or
one-half of the average of the past 6 years. This is an important reason why
many expect only modest returns for the stock market, rather than another large
rise. This includes the possibility of a correction of 10+%, which could take
some of the excesses and high valuations out of the market, and be positive for

the market's longer-term performance. So long as profit growth is reasonable and
inflation remains low, there is little reason to expect a "crash" or prolonged
bear-market in the U.S. On the contrary, the extremely favorable fundamentals in
the U.S., continued improvement in Europe, and gradual improvement elsewhere,
give many investors optimism regarding the long-term health of an investment in
the equity markets. In general, we share this view.

Growth & Income Portfolio                                


Objective

Seeks long-term growth of capital and income and a reasonable current return by
investing primarily in dividend-paying common stocks, convertibles, and readily
marketable securities that derive their value from common stocks, as well as
fixed income securities. The Portfolio does not strive to maintain a specific
balance of stocks, bonds, and money market instruments. Instead the manager
selects the industry sectors and individual securities he believes have the
highest potential for attractive total returns.


Management's
  Discussion & Analysis

During 1997, Brian Posner became the manager of this portfolio. The initiatives
of the Portfolio's new manager were most apparent during the first quarter. In
the first five weeks under Brian Posner's management, almost every security in
the Portfolio was replaced. These changes reflected his disciplined,
value-oriented investment approach. The management transition was accomplished
with an eye on dual goals; avoiding lapses in performance, and minimizing
shareholder exposure to capital gains.

PERFORMANCE
The Variable Investors Series Trust Growth & Income Portfolio had a strong
showing for 1997 closing the calendar year with a gain of 28.20% compared to
33.4% for the S&P 500 Index. During the third quarter, the fund gained almost
10.50%, outperforming the S&P by a significant margin.


One significant change to the Portfolio's composition was made within the energy
and oil & oil-services sectors. The manager believed that these stocks, which
were strong performers during 1996, had already responded earlier in 1997 to
pressures stemming from fears of declining energy prices. In these companies he
believed that the market's pessimism was extreme, particularly given their
lengthy and potentially lucrative contracts for projects in the Gulf of Mexico
and the North Sea.

Against the backdrop of the third quarter's high market volatility, the
Portfolio's value bias and focus on risk-adjusted total return met with good

results. Few changes were made during this period to the Portfolio's sector
weightings, and it remained well-diversified by industry. This reflected the
narrow valuations across sectors, which the manager viewed as leaving little
incentive to heavily overweight sectors. An exception to this view was the
Portfolio's overweighting in the financial sector where stocks had continued to
benefit from stable interest rates and ongoing deregulation and consolidation
within the industry. Notable performers for the quarter included Citicorp and
Equitable of Iowa. Provident Companies, a new financial company added during the
period, also contributed to the Portfolio's positive return.

The fourth quarter saw a modest gain in the Portfolio. Again in this quarter,
the pattern of relatively narrow valuations across industries was a significant
factor in the manager's decision not to initiate large changes in the sector
weightings. The energy and computer stocks weighed on the Portfolio's
performance, while it was helped by holdings in financial-services,
pharmaceuticals, retail and telecommunications.

Financial services remain a sizable sector in the Portfolio's holdings and are
modestly overweighted. While we continue to see good value among industry
leaders in the computer area, overall exposure was pared due largely to
Asia-related risk considerations. In the health-care sector (including
pharmaceuticals) changes were made -- among them the addition of Merck. This
stock helped the Portfolio's performance during the period, due in part to the
FDA's approval of the company's hair-growth product in December.

OUTLOOK
Looking to the first quarter of 1998 and beyond, Warburg Pincus believes the
considerable market volatility seen over the last several months is unlikely to
recede, due in part to Asia-related uncertainties. In this context, individual
security selection remains critical. The manager will continue to evaluate
stocks on a risk-adjusted total return basis, holding those he deems to have the
brightest longer-term prospects.

Multiple Strategies Portfolio                               

Objective

Seeks as high a level of total return over an extended period of time as is
consistent with prudent investment risk by investing in equity securities, bonds
and money market instruments in varying proportions, depending upon prevailing
economic and financial market conditions.

Management's
  Discussion & Analysis

On December 31, 1997 the portfolio was 72.8% invested in common stocks, 13.1% in
bonds with a mixture of high grade corporates, government, and government
agencies, and approximately 14% in short term securities. This mixture (more
weighted in stocks than a typical 60% equities/ 40% bonds balanced portfolio)
was beneficial as the S&P 500 Index posted a 33.4% return for the year. The
portfolio had a total return of 21.8% for the year, compared to 24.0% for a 60%
S&P 500 / 40% Lehman Brothers Government / Corporate Bond Index mixture, as the
equity holdings were unable to keep pace with the S&P 500.

OUTLOOK
The equity holdings in the portfolio mirror those of the Growth Portfolio and
will continue to do so. We anticipate a more conservative equity position in the
portfolio going forward, with a focus on companies whose revenues are primarily
derived from the United States economy.

We look for continued moderate economic growth of around 2.5% in 1998, as the
Asian crisis takes a point or so out of U.S. GDP growth. The outlook for
inflation remains very positive with the strong dollar and the weakening
economies in Southeast Asia. As such, we believe the long bond yield could trade
down to the 5.25-5.50% range. The real unknown at this point in time is the
extent to which the "Asian Flu" will impact corporate earnings growth.
Obviously, some industries will suffer from Asia while others will be relatively
unaffected. We believe that corporate profit growth will slow in 1998 to a mid
single digit level. We should

High Income Bond Portfolio                           

Objective

Seeks a high level of current income while secondarily seeking capital
appreciation by investing primarily in fixed-income securities, including
corporate bonds and notes, discount bonds, zero-coupon bonds, convertible
securities, and preferred stocks and bonds issued with warrants, which are rated
Baa or below by Moody's or BBB or below by Standard & Poor's or in unrated
securities determined to be of comparable quality.

Management's
  Discussion & Analysis

The major factor for the superior relative performance of high yield bonds was
the almost ideal economic environment which existed for all of 1997. Strong
steady economic growth coupled with low inflation resulted in good operating
performance for most high yield issuers. Declining interest rates (the interest
rate on 10 year U.S. Treasury securities declined approximately 70 basis points)
and strong equity markets provided an attractive financial market environment
for high yield issuers. Finally, the high yield market benefited from strong
demand for high yield securities as investors were attracted to the historically
strong total return performance of the marketplace and the attractive yields
offered by high yield securities in a falling interest rate environment. For the
year, the Portfolio returned 13.54%, compared to 12.70% for the Lehman Brothers
Single "B" Index.

PERFORMANCE

Several factors benefited the Portfolio versus the benchmarks. The Portfolio's
largest industry exposures have been (and continue to be) telecommunications,
cable and broadcasting. These three sectors generated very strong performance
versus the market during the year. The Portfolio was generally underweight basic
industries such as steel, forest products and commodity chemicals. These sectors
underperformed especially in the fourth quarter as economic concerns about 1998
began to increase. The portfolio also had no exposure to

  Discussion & Analysis (Continued)

emerging Asian markets which were negatively impacted in the fourth quarter by
finance activities such as mergers, initial public offerings (IPO's) and tenders
which proved beneficial to bondholders. AMF, Mettler Toledo and International
Home Foods did initial stock offerings and Owens Illinois and Monarch Marking
tendered for their outstanding debt. Finally, the portfolio benefited from
outstanding individual security selection avoiding major deteriorating
situations while holding numerous strong performers.

OUTLOOK
As we look out into 1998, the main area of uncertainty is what impact the
developing problems in Asia will have on U.S. economic growth, inflation and
equity markets. It would appear that the problems in Asia will serve to slow the
U.S. economy and reduce inflation much like a Federal Reserve tightening. This
could serve to head off inflationary fears, reduce the likelihood of a Fed
tightening and extend the economic expansion. An extended economic expansion
would be a long term positive for high yield bonds. The risk is that Asia's
problems have a greater impact on the U.S. economy and push the domestic economy
into recession. Superior credit selection will be essential in 1998 as the
odds-on-bet is for slower economic activity which could lead to negative credit
surprises. From a portfolio perspective, we continue to like companies that are
benefiting from secular growth like telecommunications and companies in
consolidating businesses like cable and broadcasting.

U.S. Government Bond Portfolio                                    

Objective

Seeks current income and preservation of capital. Under normal circumstances, at
least 80% of the Portfolio's assets will be invested in U.S. Government
Securities; the remainder may be invested in investment grade corporate
securities and in cash and money market instruments.

Management's
  Discussion & Analysis

After a shaky start punctuated by a Federal Reserve rate hike in early March,
the bond market powered ahead for the balance of the year. Yields were pushed
lower by a continual stream of economic reports showing that inflation was, if
not dead, at least in hibernation, despite strong economic growth. Benchmark
Treasury yields declined across all maturities beyond one year but fell most in
the longer maturities. Mortgage-backed securities outperformed Treasuries in the
first half of the year but underperformed in the second half as their durations
fell sharply amid increased refinancing activity.

In the most recent quarter, continued good news on the inflation front and the
potential slowing effects of the Asian financial meltdown contributed to a very
strong domestic bond market. Long-term yields declined by almost 50 basis points
over the period, and the yield curve flattened substantially. The quarter was
characterized by a flight to quality in the fixed income markets and a general
widening of risk premiums in all financial assets. Treasuries outperformed the
corporate market, with the Yankee portion of the corporate market
underperforming dramatically due to the Asian events.

PORTFOLIO PERFORMANCE
With the exception of a brief period in early spring of last year, we maintained
the portfolio at a neutral-with-benchmark duration of approximately 4.6 years.
The portfolio benefited from yield curve flattening (the convergence of
long-term and short-term yields) as a result of a slight barbell yield curve
posture. After keeping pace with its benchmark through September, the

Management's
  Discussion & Analysis (Continued)

portfolio underperformed slightly during the fourth quarter due to its
underweighting in Treasuries and overweighting in mortgage-backed securities.
The VIST U.S. Government Bond Portfolio returned 2.71% for the fourth quarter
and 9.37% for the year, compared to a 1 year return of 9.58% for the Lehman
Brothers Government Bond Index.

OUTLOOK
We expect the U.S. bond market will continue to be supported by good news on
consumer price inflation, although upside potential will be limited by sustained
high money market rates and little prospect for Federal Reserve easing any time
soon. The problems in Asia could ultimately lead to lower short-term interest
rates in the U.S., but such prospects are not apparent at this time as recent
policy responses appear to be reducing the prospects for additional downside
moves.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS


To the Trustees and Contract Owners of
Variable Investors Series Trust


We have audited the accompanying statements of assets and liabilities,
including the schedules of investments, of Variable Investors Series Trust (the
Trust) (comprising, respectively, the Small Cap Growth, World Equity, Growth,
Matrix Equity, Growth & Income, Multiple Strategies, High Income Bond, and U.S.
Government Bond Portfolios) as of December 31, 1997, the related statements of
operations for the year then ended, and the statements of changes in net assets
for each of the two years in the period then ended and financial highlights for
each of the three years in the period then ended. These financial statements and
financial highlights are the responsibility of Variable Investors Series
Trust's  management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits. The 
financial highlights for each of the two years in the period ended December 31, 
1994 were audited by other auditors whose report dated February 14, 1995 
expressed an unqualified opinion on those financial highlights.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned as of December 31, 1997, by correspondence with the custodian
and brokers, or by other appropriate auditing procedures where replies from
brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective portfolios constituting Variable Investors Series Trust at
December 31, 1997, the results of their operations for the year then ended, and
the changes in their net assets for each of the two years in the period then
ended and financial highlights for each of the periods in the three years then
ended, in conformity with generally accepted accounting principles.

(1)      On April 1, 1994, FVAS became investment adviser. Prior to that date,
         results were achieved by former investment advisers.
(2)      Total returns would have been lower had certain expenses not been borne
         by the adviser or its affiliates.
(3)      The performance of the Portfolio shown on this page does not reflect
         expenses and charges of the applicable separate accounts and variable
         products, all of which vary to a considerable extent and are described
         in the product's prospectus.
(4)      Net Investment Income is after payment or reimbursement of certain
         expenses by affiliates in 1997, 1996 and 1995 and waiver of business
         management fee and payment or reimbursement of certain other expenses
         by affiliates in 1994 and 1993. (See Note C to the Trust's financial
         statements.) Had affiliates not undertaken to waive their fees and/or
         pay or reimburse expenses related to the Portfolio, the Ratio of
         Operating Expenses to Average Net Assets would have been as follows:
         1997 - 1.21%; 1996 - 1.32%; 1995 - 1.33%; 1994 - 1.48% and 1993 -

         is required to disclose its average commission rate per share for
         trades on which commissions are charged. This rate does not reflect
         mark-ups, mark-downs or spreads on shares traded on a principal basis.
(7)      For 1997 and 1996, amount was less than $0.001 per share.

         expenses and charges of the applicable separate accounts and variable
         products, all of which vary to a considerable extent and are described
         in the product's prospectus.
(4)      Net Investment Income is after payment or reimbursement of certain
         expenses by affiliates in 1997, 1996 and 1995 and waiver of business

         by affiliates in 1994 and 1993. (See Note C to the Trust's financial
         statements.) Had affiliates not undertaken to waive their fees and/or
         pay or reimburse expenses related to the Portfolio, the Ratio of
         Operating Expenses to Average Net Assets would have been as follows:
         1997 - 1.73%; 1996 - 1.66%; 1995 - 1.59%; 1994 - 1.45% and 1993 -
         1.30%.
(5)      For fiscal years ending after September 1, 1995, the Portfolio is
         required to calculate an expense ratio without expense reductions.

                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1997


NOTE A -- ORGANIZATION

      Variable Investors Series Trust (the "Trust") was established as a
Massachusetts business trust under the laws of Massachusetts by an Agreement and
Declaration of Trust dated December 23, 1986. The Trust is an open-end, series
management investment company which currently comprises eight series of shares
of beneficial interest (the "Portfolios") each of which represents the entire
interest in a separate portfolio of investments. The Portfolios are the Small
Cap Growth Portfolio (formerly the Small Cap Portfolio), the World Equity
Portfolio, the Growth Portfolio (formerly the Common Stock Portfolio), the
Matrix Equity Portfolio (formerly the Tilt Utility Portfolio), the Growth &
Income Portfolio, the Multiple Strategies Portfolio, the High Income Bond
Portfolio, and the U.S. Government Bond Portfolio.

      Effective May 1, 1997, the names of the Small Cap Portfolio, the Common
Stock Portfolio and the Tilt Utility Portfolio were changed to the Small Cap
Growth Portfolio, the Growth Portfolio and the Matrix Equity Portfolio,
respectively.

      The Cash Management Portfolio was liquidated on December 3, 1997 after
Monarch Life Insurance Company received permission from the SEC to redeem its
shares. First Variable Life Insurance Company liquidated its shares on January
3, 1997, amounting to $8,214,892, and the money was transferred to the Federated
Prime Money Fund II immediately following the Company's redemption.


NOTE B -- SIGNIFICANT ACCOUNTING POLICIES

      The following is a summary of significant accounting policies followed by
the Trust in the preparation of its financial statements.

      ESTIMATES: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

      VALUATION OF INVESTMENTS: The Trust's equity securities, including
American Depositary Receipts (ADR's) and other forms of depository receipts,
traded on a national securities exchange are valued at the last sales price, or,
if no closing price is available, at a bid price estimated by a broker or
dealer. Debt securities are generally valued on the basis of valuations
furnished by pricing services which determine valuations for normal
institutional size trading units of debt securities, without exclusive reliance
upon quoted prices. These valuations are believed to reflect with greater
accuracy the fair market value of such securities. Short-term securities
maturing in 60 days or less are valued at cost plus earned discount to maturity
(amortized cost), which approximates market value. Securities in other mutual
funds are valued at the net asset value of those funds. Securities for which
current market quotations are not readily available are stated at fair value as
determined in good faith under the direction of the Trustees.

      FOREIGN SECURITIES: Foreign securities traded on a recognized securities
exchange are valued at the last sales price in the principal market where they
are traded, or, if closing prices are unavailable, at the last bid price
available prior to the time a Portfolio's net asset value is determined. Foreign
portfolio security prices are furnished by quotation services expressed in the
local currency's value and are translated into U.S. dollars at the current rate
of exchange. Foreign securities for which prices cannot be obtained by the
quotation services are valued using dealer supplied quotations.

                         VARIABLE INVESTORS SERIES TRUST
                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1997
                                   -CONTINUED-

      REPURCHASE AGREEMENTS: In connection with transactions in repurchase
agreements, the Trust's custodian takes possession of the underlying collateral
securities, the value of which at least equals the principal amount, including
interest, of the repurchase transaction. To the extent that any repurchase
transaction exceeds one business day, the value of the collateral is
marked-to-market on a daily basis to ensure the adequacy of the collateral. In
the event of default of the obligation to repurchase, the Portfolio has the
right to liquidate the collateral and apply the proceeds in satisfaction of the
obligation. Under certain circumstances, in the event of default or bankruptcy
by the other party to the agreement, realization and/or retention of the
collateral, or proceeds may be subject to legal proceedings.

      INVESTMENT TRANSACTIONS: Investment security transactions are recorded on
the date of purchase, sale, or maturity. Dividend income is recorded on the
ex-dividend date, or, in the case of dividend income on foreign securities, on
the ex-dividend date or when the Trust becomes aware of its declaration.
Interest income is recorded on the accrual basis. Realized gains and losses from
security transactions are determined on the basis of identified cost.

      FOREIGN CURRENCY TRANSLATIONS: The records of the Trust are maintained in
U.S. dollars. Foreign currency amounts are translated into U.S. dollars at a
current rate of exchange of such currency to determine the value of investments,
other assets and liabilities on the date of any determination of net asset value
of the Portfolios. Purchases and sales of securities and income and expenses are
converted at the prevailing rate of exchange on the respective dates of such
transactions. Net realized gain (loss) on foreign currency includes net realized
currency gains and losses recognized between accrual and payment dates. The
Portfolios do not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from fluctuations arising
from changes in market prices of securities held. Such fluctuations are included
with the net realized and unrealized gain or loss from investments.

      FORWARD FOREIGN CURRENCY CONTRACTS: Upon the purchase or sale of a
security denominated in foreign currency, the Trust may enter into a forward
currency exchange contract for the purchase or sale, for a fixed amount of U.S.
dollars, of an amount of the foreign currency required to settle the security
transaction in order to hedge against a change in the foreign currency exchange
rate. Accordingly, the Trust would not realize currency gains or losses between
the trade and settlement dates on such security transactions. A Portfolio may
engage in position hedging to protect against a decline in value relative to the
U.S. dollar of the currencies in which their portfolio securities are
denominated or quoted.

      The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Trust on each day and the resulting net unrealized
appreciation (depreciation) and related net receivable (payable) amount are
determined by using foreign currency exchange rates supplied by a quotation
service.

      Realized gain (loss) includes net gains or losses realized by the Trust on
contracts which have matured or which the Trust has terminated by entering into
an offsetting closing transaction.

      FORWARD COMMITMENTS: To secure prices or yields deemed advantageous at a
particular time, each Portfolio of the Trust may enter into a forward commitment
in which a Portfolio agrees on trade date to either make or receive delivery
against payment for securities on a delayed delivery basis. The price and
interest rate of such securities are fixed at trade date. For forward commitment
purchases, the Portfolio does not earn interest on such security until
settlement date.

      FEDERAL INCOME TAXES: Each Portfolio of the Trust is treated as a separate
entity for federal tax purposes. Each Portfolio of the Trust has qualified and
intends to continue to qualify each year as a "regulated investment company"
under Subchapter M of the Internal Revenue Code, as amended. By so qualifying,
the Portfolios of the Trust will not be subject to federal income taxes to the
extent that they distribute all of their taxable income, including realized
capital gains, for the fiscal year. In addition, by distributing during each
calendar year substantially all of their net investment income, capital gains
and certain other amounts, if any, the Portfolios of the Trust will not be
subject to a federal excise tax.

                                   -CONTINUED-


      As of December 31, 1997, the High Income Bond Portfolio had a realized
capital loss carryforward, for Federal income tax purposes, of $384,526
($291,888 expires on December 31, 2002, $52,592 expires on December 31, 2003,
and $40,046 expires on December 31, 2005), available to be used to offset future
realized capital gains.

      Any net capital losses incurred after October 31, within a Portfolio's tax
year, are deemed to arise on the first day of a Portfolio's next tax year. The
Portfolios incurred and elected to defer net capital losses as follows, during
such period in fiscal 1997:

</TABLE>

      EXPENSES: Expenses directly attributable to a Portfolio are charged to
that Portfolio. Expenses not directly attributable to a Portfolio are split
evenly among the affected Portfolios, allocated on the basis of relative average
net assets, or otherwise allocated among the Portfolios as the Trustees may
direct or approve.

      DIVIDENDS AND DISTRIBUTIONS: Each of the Portfolios declares and
distributes dividends from net investment income, if any, and distributes its
net realized capital gains, if any, at least annually. Income and capital gain
distributions are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles. These differences are
primarily due to utilization of capital loss carryovers, differing treatments
for foreign currency transactions and differences in the timing of recognition
of certain capital losses for financial reporting and tax purposes. Both
dividends and capital gain distributions are made in shares of such Portfolios
unless an election is made on behalf of a Separate Account to receive dividends
and capital gain distributions in cash. The Trust made the following
reclassification as of December 31, 1997:

                              PRESIDENT'S MESSAGE
- -------------------------------------------------------------------------------

Dear Shareholder:

I am pleased to present the Annual Report to Shareholders for Federated Prime
Money Fund II, a portfolio of Federated Insurance Series.

This report covers the 12-month period from January 1, 1997 through
December 31, 1997. It begins with a commentary by the fund's portfolio manager,
which is followed by a complete listing of the fund's money market holdings and
the fund's financial statements.

Over the reporting period, the fund kept shareholders' cash working -- and
accessible -- every day while maintaining a stable share price of $1.00.*

To provide a competitive daily yield, the fund invests in a diversified
portfolio of high-quality money market securities. Over the 12-month reporting
period, the fund paid a total of $0.05 per share in dividends to shareholders.
On December 31, 1997, net assets reached $60 million.

Thank you for choosing Federated Prime Money Fund II as a convenient,
professionally managed way to keep your ready cash working. We will continue to
keep you up-to-date on your investment, and welcome your comments and
suggestions.


Sincerely,

/s/  J. Christopher Donahue

*  Money market funds seek to maintain a stable net asset value of $1.00 per
   share. There is no assurance that they will be able to do so. An investment
   in the fund is not insured or guaranteed by the U.S. government.

MANAGEMENT DISCUSSION AND ANALYSIS

Federated Prime Money Fund II invests in money market instruments maturing in
thirteen months or less. The average maturity of these securities, computed on
a dollar-weighted basis, is restricted to 90 days or less. Portfolio securities
must be rated in one of the two highest short-term rating categories by one or
more of the nationally recognized statistical rating organizations or be of
comparable quality to securities having such ratings. Typical security types
include, but are not limited to, commercial paper, certificates of deposit,
time deposits, variable rate instruments and repurchase agreements.

U.S. economic growth continued at an above average pace during early 1997, but
moderately slowed as the year progressed. The unemployment rate fell to a
quarter-century low of 4.6%. Consumer spending, which accounts for two-thirds
of the U.S. economy, is on the rise, fueled in part by gains in income. These
strong economic indicators on the domestic side are being offset by the turmoil
in Southeast Asia. The combination of the slowdown in Asia and slow steady
growth in the U.S. should keep inflation in check during 1998.

Thirty-day commercial paper started the reporting period at 5.37% on January 2,
1997, and then rose as high as 5.95% on December 29, 1997, reflecting year-end
technical pressures.

Rates fell in January 1997 and February 1997 with the 30-day commercial paper
rate reaching a low of 5.24% on February 21, 1997. Rates rose dramatically in
late March 1997 and early April 1997 to a 5.57%, reflecting the 0.25% hike in
the federal funds rate. Commercial paper rates continued to trade around 5.57%
through the remainder of the year.

The target average maturity range for the fund remained in the 35- to 45-day
target range for the entire reporting period, reflecting a neutral position
regarding Federal Reserve Board policy. In structuring the fund, there is
continued emphasis placed on positioning 30 - 35% of the fund's core assets in
variable rate demand notes and accomplishing a modest barbell structure.

During the reporting period ended December 31, 1997, the net assets of the fund
increased from $45.7 to $60 million while the 7-day net yield increased from
4.77% to 5.10%.* The effective average maturity of the fund on December 31,
1997, was 41 days.

* Performance quoted represents past performance and is not indicative of
  future results. Yield will vary.

                         NOTES TO FINANCIAL STATEMENTS

                         FEDERATED PRIME MONEY FUND II
                               DECEMBER 31, 1997

ORGANIZATION
Federated Insurance Series (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "Act") as an open-end, management
investment company. The Trust consists of eight portfolios. The financial
statements included herein are only those of Federated Prime Money Fund II (the
"Fund"), a diversified portfolio. The financial statements of the other
portfolios are presented separately. The assets of each portfolio are
segregated and a shareholder's interest is limited to the portfolio in which
shares are held. The investment objective of the Fund is to provide current
income consistent with stability of principal and liquidity.

SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS
The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS
It is the policy of the Fund to require the custodian bank to take possession,
to have legally segregated in the Federal Reserve Book Entry System, or to have
segregated within the custodian bank's vault, all securities held as collateral
under repurchase agreement transactions. Additionally, procedures have been
established by the Fund to monitor, on a daily basis, the market value of each
repurchase agreement's collateral to ensure that the value of collateral at
least equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are deemed by
the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less
than the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES, AND DISTRIBUTIONS
Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

FEDERAL TAXES
It is the Fund's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS 
The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

RESTRICTED SECURITIES
Restricted securities are securities that may only be resold upon registration
under federal securities laws or in transactions exempt from such registration.
Many restricted securities may be resold in the secondary market in transactions
exempt from registration. In some cases, the restricted securities may be resold
without registration upon exercise of a demand feature. Such restricted
securities may be determined to be liquid under criteria established by the
Trustees. The Fund will not incur any registration costs upon such resales.
Restricted securities are valued at amortized cost in accordance with Rule 2a-7
under the Act.

Additional information on the restricted security held at December 31, 1997 is
as follows:

USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses, and revenues reported in
the financial statements. Actual results could differ from those estimated.

OTHER
Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST
The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (without par value). At
December 31, 1997, capital paid in aggregated $59,659,343.

Transactions in shares were as follows:

INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISORY FEE
Federated Advisers, the Fund's investment adviser (the "Adviser"), receives for
its services an annual investment advisory fee equal to 0.50% of the Fund's
average daily net assets. The Adviser may voluntarily choose to waive any
portion of its fee. The Adviser can modify or terminate this voluntary waiver
at any time at its sole discretion.

ADMINISTRATIVE FEE
Federated Services Company ("FServ"), under the Administrative Services
Agreement, provides the Fund with administrative personnel and services. The
fee paid to FServ is based on the level of average aggregate daily net assets
of all funds advised by subsidiaries of Federated Investors for the period. The
administrative fee received during the period of the Administrative Services
Agreement shall be at least $125,000 per portfolio and $30,000 per each
additional class of shares.

TRANSFER AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES

FSSC is based on the size, type, and number of accounts and transactions made

fee is based on the level of the Fund's average daily net assets for the
period, plus out-of-pocket expenses.

Fund has reimbursed the Adviser for these expenses. These expenses have been

                          INDEPENDENT AUDITORS' REPORT

To the Board of Trustees of the Federated Insurance Series
and Shareholders of FEDERATED PRIME MONEY FUND II:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Federated Prime Money Fund II, (a portfolio of
the Federated Insurance Series) as of December 31, 1997, and the related
statement of operations for the year then ended, the statement of changes in
net assets for the years ended December 31, 1997 and 1996, and the financial
highlights for the periods presented. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of the securities owned as of
December 31, 1997, by correspondence with the custodian and brokers; where
replies were not received, we performed other auditing procedures. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Federated Prime
Money Fund II as of December 31, 1997, the results of its operations, the
changes in its net assets and its financial highlights for the respective
stated periods in conformity with generally accepted accounting principles.

Variable funds are not bank deposits or obligations, are not guaranteed by any
bank, and are not insured or guaranteed by the U.S. government, the Federal
Deposit Insurance Corporation, the Federal Reserve Board, or any other
government agency. Investment in variable funds involves investment risk,
including the possible loss of principal. Although money market funds seek to
maintain a stable net asset value of $1.00 per share, there is no assurance that
they will be able to do so.

This report is authorized for distribution to prospective investors only when
preceded or accompanied by the fund's prospectus which contains facts
concerning its objective and policies, management fees, expenses, and other
