LETTER FROM THE PRESIDENT


1997 -- WHAT A RIDE!
Although some market pundits were expecting the bear market to begin rearing its
ugly head, investors were again rewarded with another outstanding year. The S&P
500 Index concluded the year with a 33.36% return, which marked the first time
in its history it posted returns of 20% or more in three consecutive years. Over
this incredible three-year period, the S&P 500 has returned more than 120%.

Certainly, all the pieces were in place to complete the picture of another
outstanding year. The U.S. economy continued to expand at a moderate pace,
inflation was firmly under control, if not nearly eliminated, and investor
confidence in the markets paved the way for strong cash-flows into the equity
markets. As we all know, while the U.S. stock market reached higher ground at
the end of the year, we also saw many more setbacks and of greater magnitude
than in the previous two years. Indeed, 1997 sensitized investors to the concept
of volatility. Briefly, let's review the influential events of 1997.

- -   Alan Greenspan's "irrational exuberance" comment in late 1996 to see the Dow
    Jones Industrial Average (DJIA) reach 7,000 in February, the fastest ever
    1,000 point ascent in the history of the index.

- -   Greenspan again shook the markets near the end of February, noting
    "excessive optimism" in the stock market.

- -   The Fed raised interest rates a quarter point near the end of March, sending
    the markets down nearly 10% during the Spring -- a sobering reminder of the
    influence of interest rates over the equity markets.

- -   Solid corporate earnings helped the DJIA to reach the 8000 mark in July,
    later pushing the index to a record high of 8259 on August 6.

- -   In late summer, many notable companies' earnings fell short of estimates.
    This sent the DJIA plunging 247 points, the single biggest point drop in the
    history of the index -- at that time.

- -   In late October, the DJIA would more than double its August swoon on news of
    the Hong Kong markets, sending the index spiraling downward 554 points, or
    7.18%. From its all time high on August 6, the DJIA had declined about 13%.

With all eyes focused on Asia, the domestic markets remained little changed for
the remainder of the year. While we can conclude that 1997 provided us with
another year of solid returns in the domestic markets, it was also one of the
more volatile one-year markets in history.

There were few, if any, asset classes not influenced by the economic forces of
1997. Benign inflation and a flight to quality took the bond markets on a
capricious ride during the course of 1997. Near the end of the year, the yield
on the benchmark 30-yield Treasury was at its lowest level in more than four
years. This was not far from October 1993's 5.78% yield, the lowest level since
the 30-year bonds were reintroduced in 1977. The yield on the 30-year bond,
which moves in the opposite direction of its price, began the year at 6.64% and
rose during much of the spring before hitting 7.71% in early April on
anticipation that the Fed would increase interest rates. A bond rally in
December, precipitated by the crisis in the Asian markets saw investors looking
for shelter and consequently led to a flight to quality. This pushed the yields
on the benchmark 30-year bond from 6.27% on October 24 down to 5.92% at year
end. In addition, the yield curve flattened almost 50 basis points as the yield
of the two year treasuries went from 5.87 to 5.64 and the long bond went from a
6.64 yield to a yield of 5.92%.
<PAGE>   2
LOOKING AHEAD
Many investment managers are proceeding ahead in 1998 as they did in 1997 --
with much due caution. It might be unrealistic to expect the kind of returns
we've seen in the last three years to continue for any length of time. Consensus
expectations project returns between 8% to 12%. Of course, the field is clearly
split between two extreme viewpoints, many cautiously looking for the bear and
others believing the bull will continue to speed ahead.

Certainly, eyes will be focused on inflation, but more so on the Fed's reaction
to inflation. Most fears of a rate increase have subsided as inflation by most
standards seems to be under control and even decreasing. However, some still
cautiously watch for wage inflation to creep into the picture and force a rate
hike. Even the currency crisis in Asia could have a positive effect on inflation
as the cost of imported goods will most likely decrease. Conversely, weak Asian
currencies and a strong dollar could squeeze the profits of American companies,
and U.S. economic growth could slow from 4% last year to 2% this year.

As always, corporate earnings will be a driver in stock performance. The market
can severely punish a stock that doesn't meet earnings expectations or reward an
undervalued stock that posts a positive earnings surprise. During these times,
an emphasis on stock picking will be of vital importance.

COVA -- COMMITTED TO VALUE
It's the basis for our name -- COmmitted to VAlue -- and it's an integral part
of our products. In an investment environment of such great uncertainty, we at
Cova are committed to providing our investors with a variety of opportunities
that should help them weather the storms. First there is a selection of
investment portfolios managed by world-class money managers covering a variety
of asset classes. Your investment management team's disciplined approach to
security analysis should provide a strong foundation for the long-term investor.

With this selection of investments, we offer a dollar cost averaging plan and
automatic portfolio rebalancing. These important financial planning techniques
help investors take a disciplined approach to managing their money and are
available at no additional charge. We also offer a fixed account that locks in a
fixed rate of interest for one calendar year. Finally, there's the aspect of
tax-deferred savings, with the triple-compounding advantage. This allows 1) your
principal, 2) your earnings, and 3) the money you would have paid in taxes to
accumulate uninhibited by taxes. In addition, transfers between portfolios in an
annuity do not generate a capital gains tax, which might be experienced in
similar investments outside of an annuity.

Now that we've recapped the events of 1997, we would be remiss not to remind you
that these are only the events of one year. Over the long-term, equities have
always rewarded investors favorably. Of course, annuities are an excellent
investment for long-term objectives, such as retirement. We consider it a
privilege to be entrusted for your long-term savings needs in 1998.

Sincerely,

/s/ L.J. Stensrud

President & CEO





P.S.     IMPORTANT NOTICE!  PROPOSED BUDGET ITEM COULD CHANGE THE TAX-DEFERRED
         STATUS OF YOUR ANNUITY...

         DEAR POLICYHOLDER: At the time of this writing, President Clinton's
         budget for 1999 contained certain proposals that would seek to impose
         taxation on non-qualified annuities. Don't allow these drastic measures
         to pass without voicing your objections to your representative in
         Washington.

GROWTH & INCOME EQUITY PORTFOLIO                   For the period ended 12/31/97
MANAGED BY MISSISSIPPI VALLEY ADVISORS
Letter to Policyholders

Stocks in the portfolio continued to perform well, despite a market correction
in October and increased volatility late in the period due to problems in many
Asian markets. Shares of large company stocks posted the strongest gains during
the period. Those gains did broaden out somewhat during the period to include
shares of some smaller firms.

We continued to take a bottom-up approach to stock selection, looking for good
values. We also took a very diversified approach toward managing the Portfolio.
We did not bet on the fortunes of any particular sector. Near year end, our
portfolio was broadly diversified with money across eight sectors with the
approximate allocations: 24% in consumer growth stocks; 21% in interest
sensitive stocks such as banks and financial institutions; 15% in industrial
cyclicals; 14% in technology stocks; 13% in consumer staples stocks; 6% in
energy stocks; 4% in capital goods stocks; and 3% in consumer cyclicals.

As the investment environment changed throughout the period, we purchased shares
of select technology companies that traded at attractive prices. We also found
opportunities among certain consumer staples stocks, as well as shares of drug
makers and industrial cyclical companies. We reduced the Portfolio's exposure to
energy stocks and capital goods stocks. Those sectors performed very well
recently and appeared to be overvalued relative to the market.

Looking ahead, we will continue to carefully select stocks that appear
undervalued. Currently, such stocks included medical and drug stocks, financial
services companies and technology firms. We also will continue to maintain a
broadly diversified portfolio, giving investors exposure to various sectors of
the stock market without taking excessive or unnecessary risks.

EQUITY INCOME PORTFOLIO                            For the period ended 12/31/97
MANAGED BY MISSISSIPPI VALLEY ADVISORS
Letter to Policyholders

The overall stock market environment was generally very favorable during the
period. Factors contributing to the stocks' strong performance were continued
corporate earnings growth, low interest rates and low inflation. The flow of
money into the stock market was also steady during the period, driven primarily
by individuals contributing to 401(k) plans.

We take a very disciplined, value-oriented approach to stock selection, focusing
on shares that offer attractive yields and are selling at low prices relative to
the stock's actual worth.

The Russell 1000 Value Index is our benchmark, so the Portfolio consists
primarily of high-quality, large-company stocks.

The financial services sector offered some of the best investment opportunities
during the period, as these stocks benefited from low interest rates and
consolidation within the banking industry. For example, we bought shares of Core
States Financial, a regional bank that has since received buyout offers from
other institutions. Those offers helped boost the stock's price. We also
increased the Portfolio's weighting in utility stocks, from approximately 5% to
10%, to take advantage of these stocks' higher yields. Two recent purchases in
this sector were Baltimore Gas & Electric and Union Electric. We were
underweighted in the telecommunications sector during the period because we felt
that the competition in the industry might hurt corporate profits. However, we
found good values in shares of SBC Communications, Bell Atlantic and U.S. West.

Looking forward, we anticipate low inflation and low interest rates, making for
predictable corporate earnings growth. In that favorable environment, we will
continue to focus on individual stock selection, looking for value in stocks
that haven't taken part in group moves.

BALANCED PORTFOLIO                                 For the period ended 12/31/97
MANAGED BY MISSISSIPPI VALLEY ADVISORS
Letter to Policyholders

The Portfolio is designed for those investors who want exposure to both equities
and fixed-income securities. Looking back over the last year, the Portfolio's
performance was affected by trends in both the stock and bond markets.

Stocks continued to perform well during the period, with shares of large-company
stocks posting the biggest gains. The Portfolio typically seeks out undervalued
shares of companies with strong earnings growth potential. High valuations in
the stock market caused us to take a relatively defensive position in stocks. We
emphasized shares of industrial cyclical stocks and consumer staples stocks.
These sectors of the market typically hold up well when overall stock prices
decline. We also reduced the Portfolio's holdings in oil and energy services
stocks.

In the fixed-income markets, prices of longer-term bonds declined through March
due to concerns that strong economic growth could lead to rising inflation. Bond
prices rose during most of the rest of the period, however, as such concerns
diminished.

The bond portion of the Portfolio is based on the Lehman Brothers Aggregate Bond
Index, an unmanaged index comprised of the Lehman Brothers Government/Corporate
Bond Index and two Lehman Brothers asset-backed securities indices. The
Portfolio invested mainly in high-quality Treasury securities and
mortgage-backed securities, as well as some bonds issued by corporations.

The Portfolio typically invests about 50% to 60% of its assets in stocks, with
the remainder in bonds. During the period, we reduced the Portfolio's stock
allocation from around 60% of assets to roughly 58%. That decision was based
largely on the possibility of declining corporate profits going forward.
Approximately 40% of the Portfolio's assets were invested in bonds, while cash
equivalents made up the remaining 10%.

We will remain cautiously optimistic about the stock market's prospects, and we
may increase the Portfolio's equity holdings to around 60% of assets in the
months ahead. Whatever happens, we will carefully monitor the financial markets
and make any necessary changes to the Portfolio that may help to enhance returns
or reduce risk.

SMALL CAP EQUITY PORTFOLIO                         For the period ended 12/31/97
MANAGED BY MISSISSIPPI VALLEY ADVISORS
Letter to Policyholders

Small-company shares underperformed large-company stocks during the first few
months of the period. In April, however, a strengthening dollar and earnings
disappointments by large companies such as Coca-Cola and Gillette contributed to
a shift in favor of small-company stocks. From April 25 to September 30, 1997,
small-company shares gained 35% versus 24% for the S&P 500. But, in the fourth
quarter, uncertainty over economic turmoil in Asia caused investors to seek
safety in shares of large, well-established companies. As a result,
small-company stocks underperformed again. Overall, 1997 marked the third
straight year that small-company stocks underperformed large-company stocks.

We were able to find excellent values in several areas of the market. For
instance, we acquired shares of broadcast companies SFX and Evergreen Media. The
Portfolio also benefited when two of our technology holdings were acquired by
larger companies: Verifone was bought by Hewlett-Packard and Network General was
acquired by McAfee Associates.

Some of our earlier investment also contributed to the Portfolio's strong
performance in the third quarter. For example, we sold SFX and Evergreen Media
after their stock prices had climbed more than 50%. The market's shift away from
small-company stocks in the fourth quarter created more buying opportunities for
the Portfolio. Technology stocks in particular were hit very hard in the fourth
quarter, allowing us to add shares of carefully selected companies such as
software maker SPSS, semiconductor and capital goods manufacturer CFM Technology
and computer-based systems company SBS Technology.

We believe that small-company stocks will continue to provide excellent values.
They offer lower price-to-earnings ratios, lower price-to-book values and more
growth potential than large-company stocks. What's more, we expect the
three-year trend of small-company stocks' under performance to reverse itself at
some point. This means the values we find now have good potential for price
appreciation. We will continue to seek out the best values in the small-cap
universe, using careful bottom-up, stock-by-stock security analysis.

BOND DEBENTURE PORTFOLIO                             For the year ended 12/31/97
MANAGED BY LORD, ABBETT & CO.
Letter to Policyholders

The Portfolio posted a solid return during the past year as the country had
another year of economic growth, low inflation and a favorable interest-rate
environment. Particularly beneficial to the portfolio's strong performance were
the Portfolio's overweightings in the telephone, media and energy sectors. The
Portfolio was also positively impacted by holdings of high-yield bonds in
industrial sectors, such as paper, chemicals and steel. Robust U.S. economic
growth provided significant increases in corporate profitability, which resulted
in improved credit ratings and strong gains for many of our holdings. Our
commitment to fundamental research is proving more meaningful as the financial
markets have little tolerance for earnings shortfalls. While U.S. Treasury and
mortgage securities provided good total returns (in the 9.0%-9 1/2% range)
during the year, they did not match the significantly higher total returns
earned by high-yield and convertible securities.

Our outlook for 1998 is for the economy to slow considerably, with growth
falling to 2% or less in the later half of the year. We expect inflation to
remain moderate. Our economic forecasts bode well for the convertible and
high-yield bond markets and should provide our management team an opportunity to
uncover value using our in-depth research process. We remain watchful of the
weaknesses in the Asian markets, but are encouraged by the fact that most of our
holdings do not have high exposure in the Asian economies. We will continue to
seek opportunities in the emerging markets of Latin America, particularly
Mexico, where our value-based investments have recently provided strong gains
for the portfolio. At this time, we are emphasizing the domestic high-yield
sector as these securities should benefit from low interest rates and a stable
U.S. economy.

MID-CAP VALUE PORTFOLIO                            For the period ended 12/31/97
MANAGED BY LORD, ABBETT & CO.
Letter to Policyholders

In an environment of continuing economic growth, low inflation and rising stock
market averages, the Portfolio continued to rely on careful stock selection in
seeking superior performance. (The Mid-Cap Value Portfolio was first offered on
November 7, 1997. Initial investing occurred August 20, 1997. Therefore, this
letter covers an abbreviated fiscal year.) The Portfolio does not seek to
emphasize particular sectors, but to focus on investing in those companies we
believe offer the best value in the mid-capitalization sector (companies with
market capitalizations ranging from $500 million to $5 billion). At the close of
the year, the Portfolio had strong exposure to the insurance, specialty chemical
and electric power sectors only because we located a number of companies
offering exceptional value in those sectors.

Over the coming year, we expect economic growth to slow and inflation to remain
moderate. As such, the yield on the benchmark 30-year U.S. Treasury bond is
likely to drop to 5 1/2% later in 1998. We are watchful of the currency crises
in Asia, but believe the absence of inflationary pressures in the U.S., combined
with the virtual elimination of the Federal budget deficit, bodes well for the
equity markets. Overall, we will continue to seek out value opportunities,
focusing on those companies with the potential for relatively strong,
predictable earnings in the economic environment we are forecasting.

We will temper our optimism with a note of caution. The stock market has
provided handsome returns over each of the past three years. Investors should
recognize that these returns are above historical norms and may be difficult to
duplicate going forward. We continue to believe that active portfolio management
and research driven stock selection will provide you the best opportunity for
strong returns in the mid-cap market.

We remain committed to helping you achieve your long-term financial goals. Thank
you for the confidence you have placed in us.

LARGE CAP RESEARCH PORTFOLIO                       For the period ended 12/31/97
MANAGED BY LORD, ABBETT & CO.
Letter to Policyholders

Over the quarter, the stock market rallied off its October low against a
backdrop of strong economic growth and low inflation. (The Large Cap Research
Portfolio was first offered on November 7, 1997. Initial investing occurred
August 20, 1997. Therefore, this letter covers an abbreviated fiscal year.) The
Portfolio's performance can be attributed to its exposure to the stocks of
select financial companies (such as banks), utilities (including electric and
regional telephone companies) and consumer noncyclicals (stocks of companies
whose performance is not directly tied to economic conditions).

Over the coming year, we expect an environment of slowing economic growth,
continued moderate inflation and declining long-term interest rates. We continue
to emphasize the financial, utility and consumer noncyclical sectors, which we
believe offer good value. Overall, we will continue to seek out value
opportunities, focusing on those companies with the potential for relatively
strong predictable earnings in the economic environment we are forecasting.

The yield on the benchmark 30-year U.S. Treasury bond is likely to decline to 
5 1/2% later in 1998 as the economy slows. We are watchful of the currency 
crises in Asia, but believe the absence of inflationary pressures in the U.S.,
combined with the virtual elimination of the Federal budget deficit, bodes well
for both the bond and equity markets.

We temper our optimism with a note of caution. The stock market has rewarded
investors with returns in excess of 20% in each of the past three years.
Investors should recognize that these returns are above historical norms and may
be difficult to duplicate going forward. We continue to believe that active
portfolio management and research driven stock selection will provide you the
best opportunity for attractive returns in the large cap market.

We remain committed to helping you achieve your long-term financial goals. Thank
you for the continued confidence you have placed in us.

DEVELOPING GROWTH PORTFOLIO                        For the period ended 12/31/97
MANAGED BY LORD, ABBETT & CO.
Letter to Policyholders

Despite an environment of strong economic growth and subdued inflation, the
fourth quarter was generally difficult for small capitalization growth stocks.
(The Developing Growth Portfolio was first offered on November 7, 1997. Initial
investing occurred August 20, 1997. Therefore, this letter covers an abbreviated
fiscal year.) Trade uncertainties brought on by the volatility in the Asian
markets, sharp price declines in oil-service stocks and broad-based troubles in
the technology sector all contributed to the overall lag in small-cap
performance relative to large-caps. Despite this environment, the portfolio
enjoyed good relative performance by emphasizing research-driven stock
selection. Our goal is to focus on those small, dynamic companies whose
underlying strengths position them to withstand downswings in the market. The
result: a portfolio of stocks that we believe should offer above-average growth
rates over the long term.

We seek to broadly diversify the portfolio, in an attempt to reduce risk. Recent
purchases have included a number of innovative small companies in the
technology, computer software, retail and health services sectors. These
companies were added in recognition of their leading market positions in their
respective industries as well as their potential to perform well in the slowing
economic environment we are forecasting.

Over the coming year, we expect slowing economic growth, continued moderate
inflation and declining long-term interest rates. While small-capitalization
stocks have underperformed their large-capitalization counterparts over the last
several quarters, we continue to believe that investing in the small-cap growth
arena will prove rewarding over the long term due to the superior earnings
growth potential these companies offer.

We remain committed to helping you achieve your long-term financial goals. Thank
you for the confidence you have placed in us.

SELECT EQUITY PORTFOLIO                              For the year ended 12/31/97
MANAGED BY J.P. MORGAN INVESTMENT MANAGEMENT
Letter to Policyholders

During the first half of 1997, the market suffered a setback when the Federal
Reserve raised the Fed Funds rate by 25 basis points from 5.25% to 5.50%.
Volatility increased as expectations of future Fed tightenings strengthened,
however, the rate remained steady as all indicators pointed to continued low
inflation, a cooling economy, and strong earnings growth. Fueled by a favorable
economy, interest rates and corporate earnings news, the stock market surged
17.44% in the second quarter.

The stock market changed its course in the second half of 1997 as the fifty
largest stocks underperformed the small and mid cap by a wide margin for the
first time in years. However, the Asian financial crisis stunned the US equity
market in October, with aftershocks reverberating throughout the remainder of
the period. The trend towards a broadening market seen in the third quarter was
abandoned as investors sought safety in the large cap, more liquid stocks.

Our approach to investing, which avoids dependence on the strength of a few
stocks or industry sectors, can underperform the broader market when buying is
heavily focused on certain subsets of the market. Since inception, our
investment strategy involved maintaining our sector neutral approach coupled
with a continued focus on individual stock selection with an emphasis on holding
a highly diversified selection of value stocks.

The biggest contributions to performance in the first half of the year came from
stockpicking in the retail and drugs sector, with Worldcom and Toys R' Us as two
examples of stocks that have positively impacted performance. The telephone and
basic industry sectors positively contributed throughout the second half of
1997. However, the service industry sector was the biggest contributor to
relative performance for the fourth quarter and calendar year with stocks such
as Tele Communications and TCI Ventures. These two issues were among the top
five performers across the entire portfolio in 1997. Stock selections in the
energy, multi-industry, and technology sectors were negative contributors to
performance during the year.

We use fundamental research to identify stocks which are underpriced relative to
their longer-term ability to grow earnings and generate cash flow. As such, we
sometimes buy stocks that are temporarily out of favor. Our investments in cable
stocks, which we overweighted significantly during the year, serve as a case in
point. Going into 1997, these stocks had languished for three years as hopes for
a 500-channel universe, video-on-demand, cable-based telephone and industry
consolidation seemed to have faded. During this period, regulators reduced basic
rates twice; meanwhile, Direct Broadcast Satellite competition increased
significantly. Desperate, the cable industry embarked on an extremely ambitious
capital investment program, plunging cash flow into negative territory. This
year also saw the successful launch of high-speed data, digital cable, and other
new service initiatives, validating recent infrastructure investments. The
confluence of these events fueled the dramatic reversal and outperformance of
stocks such as TCI, TCI Ventures and Time Warner.

We will continue to invest in attractively valued stocks where we have a high
degree of confidence in our forecasts, where we can identify events that can
cause value to be realized, and that offer a good risk-reward profile.

SMALL CAP STOCK PORTFOLIO                            For the year ended 12/31/97
MANAGED BY J.P. MORGAN INVESTMENT MANAGEMENT
Letter to Policyholders

During 1997, the Russell 2000 was able to produce a robust return of 22.4% and
continue its streak of returning greater than 16% for the third consecutive
year. However, 1997 proved to be a tremulous year for the small cap market with
volatility rising to levels not seen since 1987. In somewhat of a seesaw
fashion, the strong results in the second and third quarters were significant
enough to offset the negative results in the first and fourth quarters. The
first quarter was the worst quarter for the Russell as speculation mounted over
the Fed's need to raise interest rates causing investors to seek safety in
larger capitalization issues. This trend was reversed in the second quarter as
the Russell produced its largest quarterly gain since March of 1991. The rise in
small cap stocks continued in the third quarter as they outperformed the S&P 500
by more than 7%. In the fourth quarter, the market once again got jittery and
punished small cap stocks as fears grew over the financial crisis in Asia.

Within the Russell 2000 Index, the value sectors outperformed growth sectors by
9.8% in the quarter and by 18.9% in the one year period. Utilities and banks
were the best performing sectors in the fourth quarter, while technology, basic
industry, and drugs underperformed.

In both the third and fourth quarters the Portfolio outperformed the Russell
2000 by a substantial margin, leaving the Portfolio ahead of the benchmark for
the one year period. Not only did the Portfolio outperform the benchmark, on a
competitive basis, the Portfolio continues to look better and better in this
volatile market. The best performing sectors in the Portfolio included
technology hardware, banks and health services. Orbital Sciences was the best
performing stock in the portfolio and we continue to see Orbital as one of the
most attractive stocks in the technology sector. In December, Orbital
successfully launched eight satellites, which are a significant part of a global
communication network that it is building. The network, ORBCOMM, is designed to
provide nearly continuous low cost monitoring, tracking and messaging
communications coverage over most of the Earth's surface. Subscribers will be
able to use inexpensive communicators to send and receive short messages, high
priority alerts and other information, such as the location and condition of
automobiles, trucks, industrial equipment, shipping vessels and other remote
assets.

The sectors detracting from performance included consumer stable, miscellaneous
finance, and transportation. American Pad and Paper was one of the portfolio's
largest negative contributors to performance as it fell 22.6%. The company
announced an earnings disappointment and attributed it to the competitive
pricing environment in its commodity envelope business. We continue to like
American Pad and Paper and have increased our position during this weakness.

The 1998 forecast is similar to a year ago: We continue to believe that small
cap stocks are attractive relative to large cap stocks for two reasons: (1)
improved relative valuation due to prolonged underperformance relative to large
cap stocks, and (2) the likelihood of a strengthening or at a minimum stable
dollar.

INTERNATIONAL EQUITY PORTFOLIO                       For the year ended 12/31/97
MANAGED BY J.P. MORGAN INVESTMENT MANAGEMENT
Letter to Policyholders

Returns from the major equity markets continued to diverge widely in December.
European stocks surged, helped by falling long term interest rates and continued
optimism over the prospects for corporate profits as a result of the
strengthening U.S. Dollar. Over the year, the Italian, German and Swiss markets
showed the strongest returns gaining 33.6%, 23.3% and 43.2% respectively.

Asian equity markets continued to struggle. In Japan, stocks suffered a decline
of -24.2% in 1997, with a string of disappointing economic statistics
emphasizing the poor outlook for corporate profits. The government's package of
tax cuts was poorly received and falling stock prices continued to threaten the
health of many second-line banks and brokerage companies.

Country allocation decisions in the portfolio contributed positively throughout
most of the year. Overweight positions in Germany and France both proved
beneficial while underweighting Japan and Malaysia relative to the benchmark
contributed positively to performance. The decision to underweight the Swiss
market during the second quarter suppressed performance. In addition, our
underweighting Hong Kong during the second quarter detracted from performance as
this market was very strong during this time period. However, our underweight
position helped during the fourth quarter, as the Hong Kong market was
negatively affected by the turmoil in Asia.

Stock selection in Germany had a positive impact on performance, particularly
the overweight position in Krupp Hoesch. Our overweight position in Volkswagen
contributed positively as it outperformed its sector following settlement with
General Motors. However, we have since reduced our position in Volkswagen as
this company underperformed during the fourth quarter. In the UK, our
underweight position in British Gas and overweight position in Sears detracted
from performance. Stock selection in France contributed positively with the
Portfolio's holding in Lagarderc (media sector) which outperformed due to
defense deals and merger speculation. Another contributor in France was Societe
Generale (banking sector) which experienced better than expected results. The
Portfolio benefitted from the Japanese stock, Sony (electronics) as strong sales
in the U.S. contributed to fuel its upward move. Its music entertainment
subsidiary also generated better than expected profits. In contrast, favoring
Nissan Motor detracted from performance as it experienced slow domestic sales
due to a recent tax hike.

Currency allocation decisions added to results. The U.S. Dollar strengthened
against both the Yen and European currencies, as a robust U.S. economy led to an
increase in both short and long term rates. The overweight U.S. Dollar position
versus the Yen, boosted performance, as the Yen weakened from 120.73 to 130.02
versus the U.S. Dollar at the end of the year.

Looking ahead, most international equity markets appear fully valued, but there
is still potential for further gains particularly in Europe. Profit expectations
are still rising and, with signs of stronger domestic demand and continued
enthusiasm for corporate restructuring, further positive surprises are still
possible.

In the Pacific, Australian and New Zealand stocks offer the best value. Domestic
economic conditions are improving here too, although the expected slump in Asian
economies will have some offsetting impact. In Japan the near term outlook
remains very difficult and, although stock prices are much more reasonable, the
best companies still appear expensive in international comparisons.

The Portfolio remains overweight in the UK and Germany. In addition, we continue
to emphasize Australia and New Zealand. Japanese positions have been reduced
further to a clear underweighting versus the benchmark.

QUALITY BOND PORTFOLIO                               For the year ended 12/31/97
MANAGED BY J.P. MORGAN INVESTMENT MANAGEMENT
Letter to Policyholders

Throughout 1997, the U.S. economy continued to grow at above trend levels and
unemployment moved to cyclical lows. Income, consumption and confidence
measures, generally, remained robust as well. In spite of an ongoing drift
upward in wage rates, inflation at both the wholesale and retail levels remained
remarkably benign.

In managing the Quality Bond Portfolio, we make three key decisions to add
value. First, we determine the Portfolio's duration, which is a measure of the
Portfolio's sensitivity to changes in interest rates. The Portfolio's duration,
which averaged approximately a quarter year longer than the Salomon Investment
Grade Bond index, enhanced performance and partially offset the poor showing of
the spread sectors.

Secondly, we allocate the Portfolio's assets across the broad sectors of the
fixed income market, including governments, corporates, high-yield, emerging
market debt, international bonds, and mortgage-backed securities. During most of
the year, the Portfolio's performance benefited from our decision to overweight
mortgage backed securities and investment grade corporates while maintaining an
underweight position in U.S. Treasuries. This decision, particularly our
underweighted position in U.S. Treasuries, negatively affected the Portfolio at
the end of the year. The volatility in Asia consequently spilling into markets
worldwide, caused a 'flight to quality' with many investors. Another positive
contributor to performance was our moderate increase in the high-yield
allocation.

Finally, we select individual securities for the Portfolio. Securities are
selected on a daily basis by our portfolio managers, with substantial input from
four fixed income analysts and traders. Security selection continued to add
value during the year. The Portfolio maintained its focus on high-quality
issues, keeping the average credit quality of its holdings between AA and AAA.

We have reduced the Portfolio's position in mortgages and callable corporate
securities, as they have become particularly vulnerable with the fall in rates.
As we believe the volatility in the financial markets will not dissipate any
time soon, we have increased the Portfolio's holdings in U.S. Treasury
securities. The Portfolio remains strategically overweighted in the spread
sectors, although to a lesser degree.

LARGE CAP STOCK PORTFOLIO                            For the year ended 12/31/97
MANAGED BY J.P. MORGAN INVESTMENT MANAGEMENT
Letter to Policyholders

The S&P 500 rose 33.36% in 1997, capping an unprecedented three consecutive
years of above 20% returns. Despite spectacular returns, the market was again
relatively concentrated in 1997. Only 43% of the S&P 500 stocks outperformed the
index last year, compared with an average of 48% since 1971. The market has been
more concentrated in the last three years than any other time since the "nifty
fifty" era of the early 1970's. Further, the largest 50 stocks in the S&P 500
outperformed the smallest 450 by 5.6% in 1997.

Strong stock selection within the drug and consumer stable sectors contributed
significantly to the portfolio's performance in 1997. The single most successful
decision was to underweight Merck (+35%), which lagged the sector return of 54%.
That allowed us to overweight Schering Plough (+95%) and Warner Lambert (+68%).
Schering had been a neglected stock with solid management and an enormously
successful allergy drug, Claritin. Warner had two of the most successful drug
launches ever this year with Lipitor (a cholesterol drug) and Rezulin (a
diabetes drug), far exceeding analysts' sales estimates. The stock gave back
some of its gains in December due to side effects related to Rezulin, but
remains attractive.

In the consumer stable sector, Procter and Gamble was the best performer. P&G's
success last year can be attributed to their ability to grow sales while
simultaneously improving distribution efficiency of their product line, helping
to keep inventory levels down. A strong management team gives us confidence in
their ability to continue their success.

Stock selection in the telephone and health service sectors detracted from
performance last year and can be attributed to two stocks: AT&T and Columbia
Healthcare. AT&T (underweight in the portfolio), a laggard in the first half of
1997, has rallied on the cost-cutting reputation of its new CEO Michael
Armstrong, and the prospects of a merger as industry consolidation continues.
Indeed, in the first week of January a deal was reached with Teleport
representing a bid to penetrate the local phone markets. Shares of Columbia
Healthcare came under pressure early last year when federal investigators began
scrutinizing their medicare billing practices.

The Cova Large Cap Stock Portfolio uses valuation rankings that are generated by
our team of 26 equity research analysts. The Portfolio avoids the lowest ranked
stocks (most overvalued) in each sector of the market, and redistributes the
weight across the most undervalued stocks. Portfolio characteristics and sector
weights are matched to the index, leaving stock selection as the sole source of
incremental return.

Going forward, we will continue to invest in attractively valued stocks where we
have a high degree of confidence in our forecasts, where we can identify events
which can cause value to be realized, and which offer a compelling risk-reward
profile.

QUALITY INCOME PORTFOLIO                             For the year ended 12/31/97
MANAGED BY VAN KAMPEN AMERICAN CAPITAL
INVESTMENT ADVISORY CORP.
Letter to Policyholders

1997 was one big roller coaster ride for many market participants. The U.S.
treasury curve flattened almost 50 basis points as the yield on two year
treasuries went from a 5.87 to a 5.64, and the long bond went from a 6.64 yield
to a yield of 5.92 on December 31st. Throughout most of the year, the market was
on "Fed Watch", as many expected another tightening should inflation ever pick
up. Well, inflation remained under control, and subsequently, the Fed stayed on
hold.

The mortgage-backed sector was definitely a star performer in 1997, posting an
excess return of 121 basis points relative to the treasuries. Despite the drop
in yields, mortgage backed securities performed extremely well due to stable
prepayments, and the continued fall in volatility. Looking ahead to 1998, we are
cautious on the mortgage sector and feel that prepayment speeds will pick up due
to the drop in yields.

After performing extremely well for 3/4 of the year, Investment grade corporates
gave up most, if not all of their gains once the Asian crisis hit the market in
October. Investment grade corporates ended the year with a return of -.29%, the
first year since 1990 that they had posted a negative return. Leading the way
down was the Yankee sector, as names such as Korea Development Bank widened more
than 400 basis points since October 1st.

Due to the economic turmoil in Asia, we feel the growth rate in the U.S. economy
will slow somewhat in 1998. Consequently, the corporate market should show mixed
results throughout the year and thus, we feel a more defensive posture is
warranted. We feel the portfolio is positioned well for these conditions, as we
have continued and will continue to emphasize credit quality in the selection
process.

VKAC GROWTH AND INCOME PORTFOLIO                     For the year ended 12/31/97
MANAGED BY VAN KAMPEN AMERICAN CAPITAL
INVESTMENT ADVISORY CORP.
Letter to Policyholders

1997 provided investors with another solid year of investment performance, but
not without more volatility than what we've seen during the last several years.
Certain fundamentals and events eroded the overall market near yearend and held
down many specific sectors and stocks. These conditions notwithstanding, the
portfolio overall was well positioned and provided investors with another
excellent return.

In review, we look back in surprise at the continued strength of the sectors.
While at the end of the year, this sector began to show weakness due primarily
to events associated with Asia, banks have been significant outperformers over
the last three years. BankAmerica has shown an increasing commitment to
increasing their return on assets and was up in excess of 40% for the year.

Over the year, we did make some significant moves in our healthcare holdings.
Mainly, we realigned the holdings based on valuations while keeping the sector
weighting roughly the same. We added to our position of SmithKline Beecham,
which is one of the portfolio's larger holdings. They have one of the best
pharmaceutical distribution networks and are undervalued relative to a peer of
domestic U.S. companies. We have great expectations of them.

We still continue to have significant holdings in techs because they have a high
growth rate relative to the GDP. We added to our position in IBM, which is now
one of the largest holdings. We're seeing an acceleration of their revenue
growth and a commitment to hitting their earnings. The biggest surprise in this
group was ATT. The price of the stock bottomed at $35 in July and was selling at
$65 at year-end. This was exceptional and unexpected performance out of a stock
that most people didn't like. We were selling off our position during the first
half of the year, but as we saw the change coming, we added shares and were able
to capture some of the gains.

We did reduce our oil exposure based on the price of oil and valuations. Texaco,
another large holding, did fine and was outperforming the group until the oil
stocks started selling off near the end of the year. Texaco is more oil
sensitive than some of the other oil companies because they sold off their
chemical operations and joint ventured some of their refining and marketing
operations. It's a stock that's done well since we've held it. A related holding
is McDermott, an oil service and energy related company. We began accumulating
McDermott at about $18 near the end of '96 and we recently began selling the
stock nearly double that because we couldn't make a case for it on a valuation
basis. The price of McDermott's stock was relatively unchanged for years but a
management change signaled a buying opportunity for us.

Worthy of mention is Philip Morris, another of the larger holdings in the
portfolio. We have not added to our position while the stock has underperformed
due to uncertainty of the pending tobacco settlement. However, we do expect a
conclusive settlement to come about soon. At that point, it should be in a
position to advance, which is why we are still holding a large position in the
stock.

Looking ahead for 1998, certain fundamental and technical indicators seem to be
slowing down the change of the bull market we've enjoyed for so long. That does
not mean we'll be seeking shelter during the year, however, it does mean we will
be more cautious and selective. We'll be far more critical when looking at
balance sheets, cash flows, and how companies are getting their cash flows.
Clearly, earnings and the financial stability of a company's ability to generate
cash is more important now than at the beginning of a cycle.

INVESTMENT ADVISORY CORP.
Letter to Policyholders

The first quarter of 1997 was marked by a 25 basis point tightening in the
Federal Funds rate at the end of March. The Federal Reserve Board raised the
overnight bank rate from 5.25% to 5.50% on fears of excess demand in the
economy. Concerns that this was the first of a series of tightenings by the Fed
played havoc with the market. We shortened the weighted average maturity of the
fund to 28 days by the end of the first quarter.

The Fed watching continued into the spring as a strong economy led many to
believe the Federal Reserve Board would act preemptively before inflation roared
out of control. The yield on the 1-year Treasury bill peaked for the year at
6.07% in late April. A tight job market failed to produce expected inflation
however. Many began to believe that the economy could clip along at a healthy
pace without Fed intervention. One year Treasury bill yields fell more than 40
basis points to yield a 5.60% by the end of summer. We extended the Fund's
average maturity to 70 days during August.

The short term yield curve began to flatten substantially during the fall. Value
could no longer be found by purchasing longer dated paper. Therefore the fund
began to concentrate on paper that matured in 90 days or less. Direct issue
commercial paper provided the greatest value to the fund, with yield spreads
averaging 30 basis points above their treasury counterparts.

Turmoil in Asia dominated the market at the end of the year. Due to a flight to
quality, money poured into the U.S. treasury market from home and abroad. Yields
on treasury bills fell below the 5.50% level.

The strategy of the Portfolio remains to achieve competitive yield by investing
in only the highest rated and most liquid of securities.

In the future, we will continue to monitor the situation in Asia. Any recourse
in the Far East may lead to increased demand in the U.S. and the threat of
inflation. We will maintain a neutral position in the Portfolio until a clearer
picture on the economy materializes.

INVESTMENT ADVISORY CORP.
Letter to Policyholders

World equity returns continued their impressive ascent in 1997 and while many
countries were able to outperform U.S. equity market returns this year, domestic
investors have little cause for complaint. The U.S. equity market, as measured
by the S&P 500, posted a 33.36% increase in 1997 - marking the first time that
market returns exceeded 20% in three consecutive years. In fact, the S&P 500
provided a total return of roughly 120% over the last three years. Favorable
conditions including moderate economic growth, decelerating inflation, declining
interest rates, solid corporate earnings gains and strong cash-flows into equity
mutual funds have undoubtedly been at the root of the market's advance.

An analysis of the nature of the equity market rallies over the past three years
provides some insight to the current outlook for 1998. In 1995, equity market
returns were largely driven by a 193 basis point decline in long-term interest
rates and an 18% increase in corporate earnings. In contrast, long-term rates
rose by 69 basis points in 1996 and corporate profits grew by a more modest 8%.
The 1996 rally owed much credit to record investor flows into equity mutual
funds as well as an increase in investors' willingness to take on more risk in
their search for performance. The 1997 rally was generated by a combination of
factors seen in 1995 and 1996. Specifically, long-term interest rates declined
by 72 basis points, corporate profits grew by 12% and investor flows into equity
mutual funds remained strong. In the fourth quarter, however, investors grew
more risk adverse in response to significant increases in volatility brought
about by the Asian crisis.

As we enter 1998, and the economy enters its eighth consecutive year of
expansion, market fears of an economic slowdown brought about by the Asian
crisis remain a reality. Whatever the catalyst, many analysts expect the U.S.
economy to decelerate from its current pace. Corporate profit growth is expected
to decline to 7% in 1998 and investors may have an increasingly difficult time
purchasing all but the highest quality issues exhibiting consistent growth. This
is especially true given the recent pick-up in market volatility. In 1997,
volatility of the S&P 500 reached 18% -- just below the long-term average of
19%. In the five-year period preceding 1997, the average annual level of
volatility averaged only 10%. With corporate profit growth slowing and investors
becoming increasingly risk adverse, equity market returns will likely be more
heavily dependent on interest rate improvement to bolster valuations.

We believe that many of the fundamental underpinnings that have supported the
equity markets in the past three years remain in place. However, investors
should take note of the challenges that lie ahead and adjust their expectations
regarding market performance to more closely approximate long-term averages. As
such, we believe the Stock Index Portfolio will continue to offer favorable
returns in the year ahead.

HIGH YIELD PORTFOLIO                                 For the year ended 12/31/97
MANAGED BY VAN KAMPEN AMERICAN CAPITAL
INVESTMENT ADVISORY CORP.
Letter to Policyholders

The High Yield Portfolio posted a solid return in 1997. The gain was greater
than that of US Treasury bonds, but lagged the overall US equity market due to
several factors. First, the general economic conditions were favorable, with
modest growth and low inflation. Second, the technical condition of the high
yield market continued to be strong as money poured into high yield mutual funds
at a record pace last year. Also, a number of Collateralized Bond Obligations
(CBOs) entered the market during 1997 causing another source of strong demand
for high yield instruments.

We have six analysts working full time researching the credit quality of our
high yield bond holdings and prospective investments. Our investment selection
process continued to provide good results during the period evidenced by the
fact that we were able to avoid defaults among the companies held in the
portfolio. We also experienced gains from positive developments such as mergers
with higher quality companies as well as tender offers for bonds held.

Due to the economic turmoil in Asia, we feel the growth rate in the US economy
will slow somewhat in 1998. Consequently, the high yield market should show
mixed results throughout the year and we feel a more defensive posture is
warranted. The portfolio is positioned to perform well under these conditions as
reflected by underweighting bonds in cyclical industries and emphasizing quality
in the selection process.

(1)    If certain expenses had not been reimbursed
       by the Adviser, total return would have been
       lower and the ratios would have been as follows:

       Ratio of Operating Expenses to Average Net Assets:        1.39%           2.68%**             1.08%            1.52%**

(2)    Average commission rate paid is computed by dividing
       the total dollar amount of commissions paid during the
       period by the total number of shares purchased and sold
       during the period for which commissions were charged.

(1)    If certain expenses had not been reimbursed
       by the Adviser, total return would have been 
       lower and the ratios would have been as follows:

       Ratio of Operating Expenses to Average Net Assets:          0.68%       0.74%      0.64%     0.68%      0.86%

       Ratio of Net Investment Income to Average Net Assets:       4.91%       4.68%      5.25%     3.79%      2.47%


(2)    Average commission rate paid is computed by dividing 
       the total dollar amount of commissions paid during the
       period by the total number of shares purchased and sold
       during the period for which commissions were charged.

(1)    If certain expenses had not been reimbursed
       by the Adviser, total return would have been
       lower and the ratios would have been as follows:

       Ratio of Operating Expenses to Average Net Assets:             0.88%         1.02%      1.19%       1.49%        2.05%

(2)    Average commission rate paid is computed by dividing
       the total dollar amount of commissions paid during the
       period by the total number of shares purchased and sold 
       during the period for which commissions were charged.

1. SIGNIFICANT ACCOUNTING POLICIES

Cova Series Trust (the Trust) is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the 1940 Act). The
Trust offers eighteen diversified portfolios (each, a Fund and collectively, the
Funds) to its policyholders for investment, each of which operates as a distinct
investment vehicle of the Trust. J.P. Morgan Investment Management Inc. manages
the Small Cap Stock Portfolio, Quality Bond Portfolio, Select Equity Portfolio,
Large Cap Stock Portfolio, and International Equity Portfolio. Lord Abbett & Co.
manages the Bond Debenture Portfolio, Mid-Cap Value, Portfolio, Large Cap
Research Portfolio and Developing Growth Portfolio. Van Kampen American Capital
Investment Advisory Corporation manages the Money Market Portfolio, Quality
Income Portfolio, Stock Index Portfolio, VKAC Growth and Income Portfolio
(formerly Growth and Income Portfolio), and the High Yield Portfolio.
Mississippi Valley Advisors Inc. manages the Balanced Portfolio, Small Cap
Equity Portfolio, Equity Income Portfolio and Growth & Income Equity Portfolio.
Depending on the policyholder's contract, not all portfolios are available to
all policyholders.

The Trust commenced operations on December 11, 1989 with the Quality Income
Portfolio and High Yield Portfolio. The Money Market Portfolio commenced
operations on July 1, 1991. The Stock Index Portfolio commenced operations on
November 1, 1991. The VKAC Growth and Income Portfolio commenced operations on
May 1, 1992. The Small Cap Stock Portfolio, Quality Bond Portfolio, Select
Equity Portfolio, Large Cap Stock Portfolio, International Equity Portfolio and
Bond Debenture Portfolio commenced operations on April 2, 1996. The Balanced
Portfolio, Small Cap Equity Portfolio, Equity Income Portfolio and Growth &
Income Equity Portfolio commenced operations on July 1, 1997. The Mid-Cap Value
Portfolio, Large Cap Research Portfolio and Developing Growth Portfolio
commenced operations on August 20, 1997.

The preparation of financial statements in conformity with generally accepted
accounting principles may require management to make estimates and assumptions
that affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of income and expenses during the
reporting period. Although actual results could differ from these estimates, any
such differences are expected to be immaterial to the net assets of the Funds.

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

A. SECURITY VALUATION - Investments in securities listed on a securities
exchange are valued at their sale price as of the close of such securities
exchange. If there was no sale on such day, the securities are valued at the
mean between the most recently quoted bid and asked prices. Investments in
securities not listed on a securities exchange are valued based on their last
quoted bid price or, if not available, their fair value as determined in good
faith by the Board of Trustees. Domestic fixed income investments are stated at
values using the mean between the most recently quoted bid and asked prices.
Foreign fixed income securities are valued at their sale price as of the close
of the securities exchange on which the securities are listed. If such
valuations are not available, estimates obtained from yield data relating to
instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Board of Trustees are used.
Short-term securities with remaining maturities of less than 60 days are valued
at amortized cost, which approximates market value. The Money Market Portfolio,
in accordance with Rule 2a-7 of the 1940 Act, values its investments at
amortized cost.


<PAGE>   154
                                COVA SERIES TRUST

                          NOTES TO FINANCIAL STATEMENTS

                                DECEMBER 31, 1997



A. SECURITY VALUATION - CONTINUED

Under the amortized cost method, investments are recorded at cost and any
discount or premium is accreted or amortized, respectively, on a straight line
basis to the maturity of the investment. Value on any given date equals original
cost plus or minus accreted discount or amortized premium, respectively, to that
date. Futures contracts and options are valued based upon their daily settlement
prices. Forward currency exchange contracts are valued at forward rates and are
marked-to-market daily.

B. SECURITY TRANSACTIONS - Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Funds may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Funds will
maintain in a segregated account with their custodian assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.

C. INVESTMENT INCOME AND EXPENSES - Dividend income is recorded on the
ex-dividend date and interest income and expenses are recorded when earned or
incurred, respectively.

D. FEDERAL INCOME TAXES - It is the Trust's policy to comply with the
requirements of Subchapter M of the Internal Revenue Code applicable to
regulated investment companies and to distribute substantially all of its
taxable income, including net realized gains, if any, to its shareholders.
Accordingly, the Funds have not recorded a provision for federal income taxes.
In addition, any Funds subject to federal excise tax regulations will distribute
substantially all of their net investment income and net capital gains, if any,
in each calendar year in order to avoid the payment of federal excise taxes.

Distributions from net investment income and capital gains are determined in
accordance with federal income tax regulations which may differ from generally
accepted accounting principles. As a result, distributions from net investment
income and net realized capital gains may differ from their ultimate
characterization for federal income tax purposes due to timing differences. For
the Quality Income, Stock Index and VKAC Growth and Income Portfolios, net
realized gains and losses may differ for financial and tax reporting purposes
primarily as a result of timing differences related to open futures transactions
at year end.

The Funds utilize the provisions of the federal income tax laws that provide for
the carryforward of capital losses for eight years, offsetting such losses
against any future net realized capital gains. At December 31, 1997, the
accumulated capital loss carryforwards and expiration dates by Fund were as
follows: Money Market $77,639 expiring in 2002 and 2005, Quality Income
$2,481,691 expiring in 2002, 2004 and 2005, and High Yield $88,356 expiring in
2002, and Large Cap Research $633 expiring in 2005.

The Growth & Income Equity Portfolio and Balanced Portfolio elected to defer to
their fiscal year ending December 31, 1998, $10,043 and $1,036 of losses,
respectively, recognized during the period November 1, 1997 to 
December 31, 1997.

E. DISTRIBUTION OF INCOME AND GAINS - The Funds, except the Money Market
Portfolio, declare, pay and automatically reinvest dividends semi-annually from
net investment income. The Money Market Portfolio declares dividends from net
investment income daily and automatically reinvests such dividends daily.

Net realized gains, if any, are distributed annually. Distributions are
automatically reinvested in the Funds as additional shares.

                          NOTES TO FINANCIAL STATEMENTS

                                DECEMBER 31, 1997


F. DERIVATIVES - A derivative financial instrument, in general terms, is a
security whose value is "derived" from the value of an underlying asset,
reference rate or index. The Funds primarily use derivative instruments to
protect the Portfolios against possible changes in the market value of their
investments. All of the Funds' holdings, including derivative instruments, are
marked to market each day with the change in value reflected in unrealized
appreciation/depreciation of investments. Upon disposition, a realized gain or
loss is recognized accordingly.

The primary risks associated with the use of these financial instruments for
hedging purposes are the possibility of (a) an imperfect correlation between the
change in market value of the hedged securities held by the Funds and the change
in market value of these financial instruments, and (b) an illiquid market. As a
result, the use of these financial instruments may involve, to a varying degree,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The following are brief descriptions of derivative
instruments the Funds may hold.

a. FUTURES CONTRACTS - A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Funds generally invest in stock index futures. These contracts are generally
used to provide the return of an index without purchasing all of the securities
underlying the index or as a temporary substitute for purchasing or selling
specific securities.

Upon entering into a futures contract, the Funds are required to make initial
margin deposits with the broker or segregate liquid investments to satisfy the
broker's margin requirements. Initial margin deposits are recorded as assets due
from the broker. During the period the futures contract is open, changes in the
value of the contract are recognized as unrealized gains or losses by "marking
to market" the contract on a daily basis to reflect the value of the contract's
settlement price at the end of each day's trading. Variation margin payments are
made or received and recognized as assets due from or liabilities to the broker
depending upon whether unrealized gains or losses, respectively, are incurred.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and its basis in the contract.

b. OPTIONS CONTRACTS - A purchased option contract gives the buyer the right,
but not the obligation, to buy (call) or sell (put) an underlying item at a
fixed exercise price during a specified period. These contracts are generally
used by the Funds to provide the return of an index without purchasing all of
the securities underlying the index or as a substitute for purchasing or selling
specific securities.

Purchases of put and call options are recorded as investments, the value of
which are marked-to-market daily. When a purchased option expires, the Fund will
realize a loss equal to the premium paid. When the Fund enters into a closing
sale transaction, the Fund will realize a gain or loss depending on whether the
sales proceeds from the closing sale transaction are greater or less than the
cost of the option. When the Fund exercises a put option, it will realize a gain
or loss from the sale of the underlying security and the proceeds from such sale
will be decreased by the premium originally paid. When the Fund exercises a call
option, the cost of the security which the Fund purchases upon exercise will be
increased by the premium originally paid.



<PAGE>   156
                                COVA SERIES TRUST

                          NOTES TO FINANCIAL STATEMENTS

                                DECEMBER 31, 1997


F. DERIVATIVES - CONTINUED

The premium received for a written option is recorded as a liability. The
liability is marked-to-market daily based on the option's quoted market price.
When an option expires or the Fund enters into a closing purchase transaction,
the Fund realizes a gain (or loss if the cost of the closing purchase
transaction exceeds the premium received when the option was sold) without
regard to any unrealized gain or loss on the underlying security and the
liability related to such option is eliminated. When a written call option is
exercised, the Fund realizes a gain or loss from the sale of the underlying
security and the proceeds from such sale are increased by the premium originally
received. If a written put option is exercised, the amount of the premium
originally received will reduce the cost of the underlying security purchased.

The risk associated with purchasing options is limited to the premium originally
paid. The risk in writing a call option is that the Fund may forego the
opportunity for profit if the market price of the underlying security increases
and the option is exercised. The risk in writing a put option is that the Fund
may incur a loss if the market price of the underlying security decreases and
the option is exercised this loss can be greater than premium received. In
addition, the Fund could be exposed to risks if the counterparties to the
transactions are unable to meet the terms of the contracts.

c. FORWARD FOREIGN CURRENCY CONTRACTS - The International Equity Portfolio may
enter into forward foreign currency contracts to hedge its portfolio holdings
against future movements in certain foreign currency exchange rates. A forward
currency contract is a commitment to purchase or sell a foreign currency at a
future date at a set price. The forward currency contracts are valued at the
forward rate and are marked-to-market daily. The change in market value is
recorded by the Fund as an unrealized gain or loss. When the contract is closed,
the Fund recognizes 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.

The use of forward foreign currency contracts does not eliminate fluctuations in
the underlying prices of the securities of the Fund, but it does establish a
rate of exchange that can be achieved in the future. Although forward foreign
currency contracts to sell limit the risk of loss due to a decline in the value
of the currency holdings, they also limit any potential gain that might result
should the value of the currency increase. In addition, the Fund could be
exposed to risks if the counterparties to the contracts are unable to meet the
terms of the contracts.

G. FOREIGN CURRENCY TRANSLATION - Assets and liabilities denominated in foreign
currencies are translated into U.S. dollars at the rate of exchange at the end
of the period. Purchases and sales of securities are translated at the rates of
exchange prevailing when such securities were acquired or sold. Income is
translated at rates of exchange prevailing when interest is accrued or dividends
are recorded.

                          NOTES TO FINANCIAL STATEMENTS

                                DECEMBER 31, 1997


G. FOREIGN CURRENCY TRANSLATION - CONTINUED

The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the 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.

Reported net realized foreign exchange gains or losses arise from activity in
forward foreign currency contracts, 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 Fund's books, and the U.S. dollar
equivalent of the amounts actually received or paid. Net unrealized foreign
exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at fiscal year end, resulting
from changes in the exchange rate, and changes in the contract value of forward
foreign currency contracts.

H. REPURCHASE AGREEMENTS - The Funds may enter into repurchase agreements with
selected commercial banks and broker-dealers, under which the Fund acquires
securities as collateral and agrees to resell the securities at an agreed upon
time and at an agreed upon price. The Fund accrues interest for the difference
between the amount it pays for the securities and the amount it receives upon
resale. At the time the Fund enters into a repurchase agreement, the value of
the collateral securities including accrued interest will be equal to or exceed
the value of the repurchase agreement and, for repurchase agreements that mature
in more than one day, the seller will agree that the value of the collateral
securities including accrued interest will continue to be at least equal to the
value of the repurchase agreement.

I. REVERSE REPURCHASE AGREEMENTS - The Funds may enter into reverse repurchase
agreements with selected commercial banks or broker-dealers. In a reverse
repurchase agreement, the Fund sells securities as collateral and agrees to
repurchase them at a mutually agreed upon date and price. This practice is the
equivalent of borrowing using the securities as collateral and can create
leverage. During the reverse repurchase agreement period, the Fund continues to
receive principal and interest payments on these securities but pays interest to
the counter-party based upon competitive market rates at the time of issuance.
At the time the Fund enters into a reverse repurchase agreement, it will
establish and maintain a segregated account with the custodian containing liquid
assets having a value not less than the repurchase price (including accrued
interest). If the counterparty to the transaction is rendered insolvent, the
ultimate realization of the collateral securities to be repurchased by the Fund
may be delayed or limited.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES - The
Trust has entered into an investment advisory agreement with Cova Investment
Advisory Corporation (the "Adviser"), pursuant to which the Adviser manages the
investment operations of the Trust's affairs. The Adviser has entered into
sub-advisory agreements with J.P. Morgan Investment Management Inc., Lord Abbett
& Co., Van Kampen American Capital Investment Advisory Corporation, and
Mississippi Valley Advisors Inc. ( the "Sub-advisers") for investment advisory
services in connection with the investment or management of the portfolios of
the Funds. The Adviser supervises the Sub-advisers, sub-advisers'

6. MORTGAGE AND ASSET BACKED SECURITIES

The Quality Income and Quality Bond Portfolios invest in Mortgage and Asset
Backed Securities. A Mortgage Backed Security (MBS) is a pass-through security
created by pooling and selling participations in the principal and interest
payments received from borrowers. Most of these securities are issued by
federally sponsored agencies -- Government National Mortgage Association (GNMA),
Federal National Mortgage Association (FNMA), Federal Home Loan Mortgage
Corporation (FHLMC) or Federal Home Loan Bank (FHLB).

A Collateralized Mortgage Obligation (CMO) is a bond which is collateralized by
a pool of MBSs. The Quality Income and Quality Bond Portfolios also invest in
REMICs (Real Estate Mortgage Investment Conduits) which are simply another form
of CMO. These MBS pools are divided into classes or tranches with each class
having its own characteristics. For instance, a PAC (Planned Amortization Class)
is a specific class of mortgages with the most stable cash flow and the lowest
prepayment risk.

Asset Backed Securities are similar to MBSs but made up of pools of other
assets, such as credit card receivables, which are grouped together for
investment purposes. Payments of principal and interest on the securities are
made from the cash flows of the group of assets.
