PRESIDENT'S LETTER

Dear Shareholder:

     Following three consecutive years of losses, equities finally recorded
gains for 2003. Between 2000 and 2002, the NASDAQ Composite (the "NASDAQ") lost
a cumulative 66.87%. In 2003, though, it led the major equity indices with a
total return of 50.77%; it actually gained 58.18% from its low in March. The S&P
500 Stock Composite Index (the "S&P 500") returned 28.68% for the year, while
the returns on more than half of its constituent stocks exceeded even that. The
Dow Jones Industrial Average (the "Dow") performed similarly, returning 28.29%
for the year.

     Aside from the gains for corporate investment grade and high-yield issues,
fixed income returns largely trailed those of equities. The Lehman Brothers U.S.
Aggregate Index, which includes U.S. Treasury, mortgage-backed and corporate
securities, returned just 4.10% for 2003. Similarly, Lehman's U.S. Treasury
Index and its Fixed Rate Mortgage Backed Securities Index returned 2.24% and
3.07%, respectively. The Lehman Brothers Corporate Investment Grade Index,
though, recorded a return of 8.24%. Lower-quality, high-yield issues performed
the best among domestic fixed income sectors, as Lehman's U.S. High Yield Index
returned 28.97%.

     Boosted by tax cuts and low interest rates, the economy improved
dramatically in 2003. After showing growth of only 1.4% for the first quarter,
the nation's gross domestic product (GDP) expanded at an annualized rate of 3.1%
in the second quarter and an astonishing 8.2% for the third quarter. Observers
of the economy anticipate that it expanded again in the fourth quarter,
estimating it did so at an annualized rate of 4.5%.

     After having languished for almost two years, corporate earnings
strengthened substantially in 2003. Reported earnings for the S&P 500 are
estimated to have grown more than 60% over 2002 earnings. The improvement comes
from a combination of cost cutting, productivity gains and recovering sales.
Analysts expect earnings growth to slow for 2004, but to a still-healthy pace of
around 10-14%.

     The nation's unemployment rate peaked at 6.4% in June after starting the
year at 6.0%. It declined to 5.7% by the end of the year, but still shows that
corporations have been conservative in hiring despite the improving economy. We
are presently at the stage of recovery where hiring should increase; the next
few months will be telling in that regard.

     The Federal Reserve Board (the "Fed") generally influences domestic
monetary policy by altering the target federal funds rate, the rate at which
banks lend money to each other. It uses this tool to either slow or stimulate
the economy, raising rates when it believes the economy's strength could lead to
inflation, or dropping them to boost economic activity. In June, the Fed cut
this benchmark rate from 1.25% to 1%, citing its concerns for deflation as
rationale for its 13th consecutive cut.

     Symptomatic of low domestic interest rates and the nation's trade and
budget deficits, the dollar declined in value relative to other currencies for
much of 2003. This has benefited U.S. companies that derive substantial revenues
from overseas markets, as it has made prices for their goods more competitive
relative to those of foreign companies. The dollar's value relative to other
world currencies increased during the 1990s due to the U.S. economy's strength
relative to other economies. Therefore, a decline in the value of the dollar now
should not cause concern as long as its value begins to stabilize.

     The Fund's portfolios were impacted by macroeconomic factors to the extent
that these factors affected the behavior of the financial markets. Equities
benefited from improving earnings and monetary stimulus, while the fixed income
markets were impacted by budget and trade deficits and rising interest rates. In
addition, reflecting the demand for risky assets, lower-quality financial assets
generally outperformed higher-quality financial assets. The following are our
thoughts regarding the performance of the portfolios during 2003.

                                        2
<Page>

     VALUE GROWTH: For 2003, the equity markets were led by low quality stocks
such as those in the technology and consumer discretionary sectors. Serving as a
proxy for richly valued technology stocks, the NASDAQ's returns topped those of
most equity indices. Similarly, the S&P 500's technology sector was the
benchmark's best performer for the year; close behind technology was the S&P
500's consumer discretionary sector. Of interest is the fact that most mutual
fund managers heavily overweighted both sectors during 2003.

     For the twelve-month period, the Value Growth Portfolio returned 30.68%,
modestly outperforming the S&P 500 in spite of having far less exposure to the
technology and consumer discretionary sectors. It has, instead, been overweight
in higher quality sectors such as health care, consumer staples, energy and
utilities. As several of these sectors did not perform as well as the lower
quality sectors, the Portfolio's performance was attributable to individual
security selection, as well as timing of purchases and sales. Going into 2004,
we expect the Portfolio to benefit from its exposure to the health care and
consumer staples sectors, both of which tend to benefit from rotation in sector
leadership that occurs as earnings growth slows. For this reason, we do not
anticipate making significant changes to sector weightings at the present time.

     HIGH GRADE BOND: The two-year Treasury yield rose by 22 basis points (.22%)
to 1.82%, the ten-year Treasury yield rose 43 basis points (.43%) to 4.25%, and
the thirty-year Treasury yield rose 29 basis points (.29%) to 5.07% over the
twelve-month reporting period ended December 31, 2003. The best performing
sector of the Lehman Brothers U.S. Aggregate Index ("Aggregate Index") for this
period was the Investment Grade Corporate Securities sector, as corporate
spreads declined due to strong technical factors, as well as an improvement in
the fundamental credit quality of the investment grade corporate bond market.

     The Portfolio returned 5.43% for the twelve-month period, which exceeded
the return of the Aggregate Index. The Portfolio's larger exposure to the
outperforming corporate bond and fixed rate mortgage-backed sectors and lower
duration than the Aggregate Index during a period of rising interest rates more
than offset the Portfolio's higher exposure to underperforming cash equivalents
and Portfolio expenses.

     Given the relatively low level of interest rates and the continuing signs
that the economy is recovering we continue to feel that it is not an appropriate
time to take on a larger amount of interest risk than the Aggregate Index.
However, given the very steep yield curve it is costly to remain in cash so we
will keep the majority of the Portfolio invested in intermediate maturity
securities.

     STRATEGIC YIELD: The Lehman Brothers U.S. High Yield Index ("High Yield
Index") recorded excellent results for the one year period ending December 31,
2003, with a 28.97% return. The option-adjusted spread on the High Yield Index
finished the current period at 394 basis points (3.94%) which was 457 basis
points (4.57%) lower than at the start of the reporting period. On a fundamental
basis a continued decline in defaults and improvement in the credit rating
upgrade-to-downgrade ratio helped the high yield market. Technically, the market
was helped by very strong cash inflows into high yield funds over the reporting
period.

     During the most recent fiscal year, the Portfolio produced a total return
of 11.97%, lagging that of the High Yield Index. Its performance was hindered by
having less exposure to both high yield issues and lower rated issues relative
to the Index; in general, the lowest rated issues were the best performers
during the period. A higher exposure to cash and investment grade corporate
securities than the Index, the underperformance of several individual issues,
and Portfolio expenses, also helped to lower our returns relative to the Index.

     It appears that the high yield market may be getting a little ahead of the
fundamentals. Given that it has dramatically outperformed the investment grade
bond market, we may be more inclined to lean toward lower investment grade
issues when making new acquisitions.

     MANAGED: The Managed Portfolio lagged the S&P 500 for 2003, returning
22.72%, but it readily outperformed the Lehman Brothers U.S. Aggregate Index.
Given its value bias, its exposure to cash and fixed income securities and lower
volatility in its returns relative to the S&P 500, the Portfolio's risk profile
is currently substantially below that of the equity benchmark. Per the
Portfolio's objective, its risk profile is also above that of the fixed income
benchmark.

                                        3
<Page>

     As of December 31, 2003, the Portfolio was allocated 65.72% to equities,
13.85% to fixed income securities and 20.43% to cash. We would anticipate
drawing the cash level down some if interest rates were to rise or if we were to
find attractively valued equity securities. At this time, though, interest rates
are not attractive enough to warrant additions to the Portfolio's fixed income
holdings. Similarly, we are currently finding few attractively valued equities
to add to the Portfolio's equity exposure.

     MONEY MARKET: At the last meeting of the Federal Open Market Committee
("FOMC") meeting, the FOMC articulated that the risks of inflation and deflation
were equally balanced, which was a change from its prior emphasis on avoiding
deflation. The committee is comfortable that there is growth in the U.S. economy
but is still holding off on raising interest rates until jobs recover.
Businesses remain reluctant to add to payrolls and can do so because there are
outsized productivity gains which should keep the FOMC on hold for much of 2004.
The current Federal Funds rate of 1.00% should hold until the FOMC sees risks
weighted strongly in either direction.

     BLUE CHIP: True to its passive strategy, the performance of the Blue Chip
Portfolio over the past twelve months has reflected that of the large
capitalization sector it represents. The Portfolio's total return for the period
was 25.70%. The Portfolio will remain substantially invested in common stocks of
large companies and is designed for those investors who prefer substantial
exposure to common stocks at all times, or who wish to make their own market
value judgments.

     We appreciate your investment in the Fund and we take seriously our task of
seeking to grow and protect that investment. Thank you for continued support of
the Fund.

                                        /s/ Craig A. Lang

                                        CRAIG A. LANG

     For 2003, the Value Growth Portfolio outperformed its benchmark, the S&P
500 Stock Composite Index ("S&P 500"). The equity markets, in general, awarded
more risky and lower quality securities with the highest returns for 2003. In
particular, sectors such as technology and consumer discretionary outperformed
most others within the S&P 500.

     The Portfolio, however, has much less exposure to the S&P 500's lower
quality sectors. Instead, it is overweight in high quality sectors such as
health care, consumer staples, energy and utilities. Because these sectors
tended to underperform most others for the year, the Portfolio's performance
relative to the benchmark can be attributed to individual security selection.

     The Portfolio also attained a high correlation to the benchmark in 2003. We
have positioned the Portfolio to achieve a modest correlation to the S&P 500,
but given its sector weightings, we view the high correlation the Portfolio
recorded in 2003 to be anomalous; we would not expect it to continuously record
such a high correlation going forward.

     During the twelve-month period ended December 31, 2003, the High Grade Bond
portfolio outperformed the Lehman Brothers U.S. Aggregate Index, as reflected by
the 5.43% total return produced by the Portfolio versus the 4.10% total return
produced by the Index.

     The total returns for the major components of the Lehman Brothers U.S.
Aggregate Index for this period were as follows: U.S. Fixed Rate Mortgage Backed
Securities (36% of the Index), 3.07%; U.S. Government Securities (34% of the
Index), 2.36%; and U.S. Investment Grade Corporate Securities (22% of the
Index), 8.24%. The Index had an effective duration(1) of 4.50 as of December 31,
2003. In comparison, the Portfolio had approximately 41% of its assets invested
in fixed rate mortgage-backed securities, 33% in corporate securities and 25% in
cash equivalents. The effective duration of the Portfolio was 3.40. The
Portfolio outperformed the Index mainly because it had a higher exposure to
outperforming corporate and fixed rate mortgage-backed securities and a lower
amount of interest rate risk than the Index. These positives more than offset
the Portfolio's higher exposure to underperforming cash than the Index and
Portfolio expenses.

     The composition of the Portfolio at the end of the reporting period was
approximately similar to that at the start with a slight decrease in fixed rate
mortgage-backed issues and a slight increase in cash equivalents. Going forward,
we anticipate continuing to maintain a duration below that of the Index as we
feel the risk of rising interest rates outweighs the possible upside from
falling rates at the present time.

- ----------
(1) Duration is a measure of interest rate risk for individual securities and
    portfolios. The lower the duration for a security or portfolio, the less
    sensitive it is to movements in interest rates.

     During the twelve-month period ended December 31, 2003, the 11.97% total
return produced by the Strategic Yield Portfolio was greater than the 11.24%
return produced by the Lehman Brothers U.S. Credit/High Yield Index. The total
returns for the two components of the Lehman Brothers U.S. Credit/ High Yield
Index over this period were as follows: U.S. Investment Grade Credit (80% of the
Index), 7.70%; and U.S. High Yield (20% of the Index), 28.97%. In comparison,
the Portfolio had approximately 24% of its assets invested in corporate
securities rated investment grade by both Moody's and Standard & Poor's, 57% of
its assets invested in corporate securities rated as non-investment grade or
high yield by Moody's and/or Standard & Poor's and 19% of its assets invested in
cash equivalents. The Portfolio outperformed the overall Lehman Brothers U.S.
Credit/High Yield Index due to its larger exposure to the outperforming high
yield sector relative to that Index, which more than offset the Portfolio's
higher exposure to underperforming cash equivalents and Portfolio expenses.
However, the Portfolio underperformed the Lehman Brothers U.S. High Yield
component of the Index due to its lower exposure to the high yield sector and a
higher exposure to underperforming cash equivalents than that component of the
Index, as well as Portfolio expenses.

     The Portfolio has historically invested in a mix of high yield and
investment grade issues attempting to find attractive issues in both markets.
Given the current narrower spreads available in the high yield market, we may
lean toward adding more lower investment grade issues to the Portfolio. As
always, we will attempt to seek out securities in both the investment grade and
non-investment grade markets that we feel offer attractive potential returns for
the amount of risk taken.

     The Managed Portfolio underperformed the S&P 500 for the year, but it
outperformed the Lehman Brothers U.S. Aggregate Index. For 2003, equities,
particularly those of the lowest quality, largely outperformed fixed income
securities, whose total returns were affected by rising interest rates.

     For much of 2003, the Portfolio had roughly 65% of its assets invested in
equities. Because its equity holdings are high quality and value-oriented, and
because the Portfolio was not fully invested in equities, its returns lagged
that of the S&P 500. However, due to its quality equity holdings and its fixed
income and cash positions, the Portfolio experienced substantially lower
volatility in returns than did the S&P 500.

     The Blue Chip Portfolio is designed to represent the large capitalization
sector of the domestic equity market. It remains substantially invested in
approximately 50 such common stock issues, consisting of the 30 companies in the
Dow Jones Industrial Average (the "Dow") and roughly 20 stocks of the S&P 500's
largest companies not also in the Dow. Accordingly, the Portfolio's performance
will roughly parallel that of the Dow and the S&P 500.

EQUITRUST VARIABLE INSURANCE SERIES FUND
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2003

1.   SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

     EquiTrust Variable Insurance Series Fund (the "Fund") is registered under
the Investment Company Act of 1940, as amended, as a no-load, open-end
diversified management investment company and operates in the mutual fund
industry. The Fund currently consists of six portfolios (known as the Value
Growth, High Grade Bond, Strategic Yield, Managed, Money Market and Blue Chip
Portfolios). Shares of the Fund are sold only to certain life insurance
companies' separate accounts to fund the benefits under variable insurance
contracts issued by such life insurance companies, including Farm Bureau Life
Insurance Company and EquiTrust Life Insurance Company (see Note 3).

SECURITY VALUATION

     All portfolios, other than the Money Market Portfolio, value their
investment securities that are traded on any national exchange at the last sale
price on the day of valuation or, lacking any sales, at the mean between the
closing bid and asked prices. If the mean is not available, exchange-traded
securities are valued using the prior day's closing prices. Investments traded
in the over-the-counter market are valued at the mean between the bid and asked
prices or yield equivalent as obtained from one or more dealers that make
markets in the securities. Investments for which market quotations are not
readily available, or holdings where liquidation at quoted market prices is
questionable, are valued at fair value as determined in good faith by the Fund's
Board of Trustees. Short-term investments are valued at market value, except
that obligations maturing in 90 days or less are valued using the amortized cost
method of valuation described below with respect to the Money Market Portfolio,
which approximates market.

     The Money Market Portfolio values investments at amortized cost, which
approximates market value. Under the amortized cost method, a security is valued
at its cost on the date of purchase and thereafter is adjusted to reflect a
constant amortization to maturity of the difference between the principal amount
due at maturity and the cost of the investment to the portfolio.

INCOME AND INVESTMENT TRANSACTIONS

     For financial reporting purposes, investment transactions are recorded on
the trade date. The identified cost basis has been used in determining the net
realized gain or loss from investment transactions and unrealized appreciation
or depreciation on investments. Dividend income is recorded on the ex-dividend
date and interest is recognized on an accrual basis. Discounts and premiums on
investments purchased are amortized over the life of the respective investments.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

     On each day that the net asset value per share is calculated in the High
Grade Bond, Strategic Yield and Money Market Portfolios, that Portfolio's net
investment income will be declared, as of the close of the New York Stock
Exchange, as a dividend to shareholders of record prior to the declaration. With
respect to the High Grade Bond and Strategic Yield Portfolios, any net
short-term and long-term gains will be declared and distributed periodically,
but in no event less frequently than annually. Dividends and distributions of
the other portfolios are recorded on the ex-dividend date. Dividends and
distributions from net investment income and net realized gain from investments
are determined in accordance with federal tax regulations, which may differ from
accounting principles generally accepted in the United States. These differences
are primarily due to differing treatments for certain defaulted securities, and
basis adjustments resulting from corporate reorganizations. Permanent book and
tax basis differences are reclassified within the capital accounts based on
their federal tax-basis treatment; temporary differences

                                       39
<Page>

do not require reclassification. During the year ended December 31, 2003, there
were no permanent adjustments reflected in the statements of assets and
liabilities.

     Dividends and distributions which exceed net investment income and net
realized capital gains for financial reporting purposes, but not for tax
purposes, are reported as dividends in excess of net investment income or
distributions in excess of net realized capital gains. To the extent
distributions exceed current and accumulated earnings and profits for federal
income tax purposes, they are reported as returns of capital distributions.

USE OF ESTIMATES

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States 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.

2.   FEDERAL INCOME TAXES

     No provision for federal income taxes is considered necessary because the
Fund is qualified as a "regulated investment company" under the Internal Revenue
Code and intends to distribute each year substantially all of its net investment
income and realized capital gains to shareholders.

     As of December 31, 2003, the following Portfolios had approximate net
capital loss carryforwards set forth below:

REPORT OF INDEPENDENT AUDITORS

The Board of Trustees and Shareholders
EquiTrust Variable Insurance Series Fund

     We have audited the accompanying statements of assets and liabilities,
including the schedules of investments, of EquiTrust Variable Insurance Series
Fund [comprised of the Value Growth, High Grade Bond, Strategic Yield, Managed,
Money Market and Blue Chip Portfolios] as of December 31, 2003, and the related
statements of operations for the year then ended, the statements of changes in
net assets for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended. 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 auditing standards generally
accepted in the United States. Those standards require that we plan and perform
our 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, 2003, by correspondence with
the custodian. 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 the EquiTrust Variable Insurance
Series Fund at December 31, 2003, and the results of their operations for the
year then ended, the changes in their net assets for each of the two years in
the period then ended, and the financial highlights for each of the five years
in the period then ended, in conformity with accounting principles generally
accepted in the United States.

       (g)    AGGREGATE NON-AUDIT FEES: For the Fund's fiscal year ended
              December 31, 2002, the aggregate non-audit fees billed by the
              Fund's principal accountant for services rendered to the Fund, the
              Fund's investment adviser and any entity controlling, controlled
              by, or under common control with the adviser that provides ongoing

       (h)    The Audit Committee of the Board of Directors of the Fund has
              reviewed the statement of independence provided by Ernst & Young,
              the Fund's principal accountant, considered whether the provision
              of additional services by the firm is compatible with such firm's
              independence with respect to the Fund, and concluded that the
              additional services provided by Ernst & Young does not compromise
              that firm's independence with regard to the Fund.

              recent fiscal half-year that has materially affected, or is
              reasonably likely to materially affect, the registrant's internal
              control over financial reporting.
