PRESIDENT’S LETTER

Dear Shareholder:

Following a weak first half, equities generally rebounded in the second half and finished the year ended December 31, 2005 with gains. The broad-market S&P 500 Stock Composite Index (the “S&P 500”) finished the year up 4.91% after trudging through a decline of about 1% in the first six months of the year. Both the Dow Jones Industrial Average and the NASDAQ Composite overcame their losses from the first half of 2005, finishing the year with gains of 1.72% and 2.12%, respectively.

Rising interest rates negatively impacted returns across the fixed-income universe in 2005. Because of the inverse relationship between interest rates and bond values, bond values fell as market interest rates rose during the year, offsetting a significant portion of investors’ return from coupon payments. The Lehman Brothers U.S. Aggregate Index (the “Aggregate Index”) returned 2.43% for 2005, and returns within the U.S. fixed-income universe were similar.

The economy motored along through 2005, with growth of the Gross Domestic Product for the year likely running close to 3.5%. Even with the year’s significant appreciation in energy prices, inflation in 2005 was comparable to the historical average of between 3.0% and 3.5%. This encouraged the Federal Reserve Board to continue to fight inflation with its rate-raising campaign through the end of the year, but long-term interest rates reacted little to the year’s inflation numbers. Short-term rates rose considerably during the year and, as a result, there is now little spread between short-term and long-term market interest rates.

Aggregate equity valuation has improved over the past several years, particularly among large-cap issues, but it remains above-average relative to historical measures. Meanwhile, interest rates — particularly long-term rates — are still low and below average. In this environment, we continue to emphasize the importance of maintaining an appropriate asset allocation plan. The EquiTrust portfolios provide a means for our investors to gain exposure to the domestic equity and fixed income markets.

Money Market: The interest rates offered by money market funds are closely related to the target rate set by the Federal Open Market Committee (“FOMC”). The FOMC meets several times throughout the year to determine the target Federal Funds rate (the overnight lending rate between banks). The Federal Funds rate has been raised from 1.00% to 4.25% over the last thirteen meetings. Inflation, consumer spending, and unemployment numbers have been key FOMC concerns throughout 2005. The FOMC will finish the tightening cycle when economic data suggests deterioration to a more sustainable level of growth. The hurricanes of 2005, once a major economic concern, are currently viewed by the committee as not material to the long-term health of the U.S. economy. The FOMC does believe, however, that a neutral rate level is in sight. The most recent FOMC statement implies the current economic data will be critical to the upcoming rate decisions. The Federal Funds target rate is expected to be 4.50% in the first half of 2006. On December 31, 2005, the Money Market Portfolio had a 7-day yield of 4.03%.

High Grade Bond: During a year when U.S. long term rates were expected to rise and the FOMC continued the “measured” campaign of hiking the Federal Funds Rate 25 basis points at every meeting, the Lehman Brothers U.S. Treasury Index was able to produce a 2.79% total return in 2005. During the year the Treasury curve continued to flatten with the two-year Treasury yield rising 133 basis points to 4.40% while the ten-year Treasury yield rose 17 basis points to 4.39% and the thirty-year Treasury yield fell 29 basis points to 4.54%. The Lehman Brothers U.S. Fixed Rate MBS Index (35% of the Aggregate Index) had a return of 2.61% during 2005. This Index finished the year as the second worst performing component of the Aggregate Index with –37 basis points of excess return compared to duration neutral Treasuries. This poor performance was driven mainly by increases in overall interest rates and the high negative convexity that this Index had at the start of the year. The Lehman Brothers U.S. Treasury Index (25% of the Aggregate Index) had a total return of 2.79% for the year. The Lehman Brothers U.S. Investment Grade Corporate Index (19% of the Aggregate Index) was the worst performing component of the Aggregate Index with a 1.68% total return and –115 basis points of excess return. Unlike the results in 2004, lower quality issues tended to underperform during the year with the Baa quality bucket producing an excess return of –233 basis points compared to 133, 69 and 3 basis points of negative excess return for the A, Aa, and Aaa rated buckets, respectively. The Investment Grade Corporate Index had an option-adjusted spread of 90 basis points as of December 30, 2005, which was only 9 basis points higher than year-end 2004. We feel that the overall solid credit quality and the strong technicals of the investment grade credit market are fully reflected in current spread levels. The Lehman Brothers U.S. Agency Index (12% of the Aggregate Index) had a total return of 2.33% and an excess return of 13 basis points.

Given our view that the FOMC is not done raising the Federal Funds rate and the narrow level of spreads we feel it is not an appropriate time to take on more interest rate risk than the Aggregate Index.

Strategic Yield: For the year ended December 31, 2005, the Lehman Brothers U.S. High Yield Index (the “High Yield Index”) had a return of 2.74% (47 basis points excess return relative to duration neutral Treasuries) which exceeded the return of

2

1.68% (–115 basis points excess return relative to duration neutral Treasuries) produced by the U.S. Investment Grade Corporate Index, but was less than the 4.91% total return of the S&P 500. On a fundamental basis, a continued low level of defaults and fairly stable credit trends helped the high yield market outperform the investment grade corporate market. The yield on the High Yield Index increased to 8.25% from 6.76% while the option-adjusted spread rose 69 basis points to 357 basis points over the course of 2005. But returns were mixed by credit rating within the High Yield Index in 2005. Caa rated bonds were the worst performer with a .64% return while single-B rated and Ba-rated issues returned 3.53% and 2.88%, respectively.

In general, we continue to feel that the investment grade and non-investment grade corporate markets are fully valued. Because of this we may add more Government Agency issues, as well as look for attractive issues in the corporate market.

Managed: As noted above, the S&P 500 returned 4.91% on a total return basis in 2005. The Managed Portfolio trailed that just modestly with a total return of 4.53% for the period.

The Managed Portfolio holds equities, high quality fixed income securities and cash-like instruments, so its returns will generally reflect this composition. For 2005, its equity exposure modestly trailed the S&P 500, primarily due to lagging performance by the Portfolio’s holdings in the financials and materials sectors. Similar to many segments in the domestic fixed income universe, the Portfolio’s fixed income holdings declined with the rise in interest rates. The Portfolio’s cash holdings recorded a positive return for the year but still trailed the gain of the S&P 500, further impacting its performance against the benchmark.

From a value standpoint, equities remain more attractive compared to high quality fixed income issues, and so we remain more inclined to add to the Portfolio’s equity exposure than to its fixed income allocation. That said, cash instruments will likely offer competitive returns in the near-term.

Value Growth: The Value Growth Portfolio modestly outperformed the S&P 500 for 2005, with a total return of 6.41% compared to 4.91% for the benchmark.

The Portfolio outperformed the S&P 500 primarily due to higher returns in the energy and consumer discretionary sectors, but its consumer staples and industrials holdings also contributed gains for the year. Lagging returns in the Portfolio’s financials and materials holdings, however, did offset some of the positive relative performance elsewhere.

The Portfolio has a notably large-cap tilt, as during the year we increased its weighting in this segment of the equity market considerably. Aggregate valuation for the market is fair, but large-cap stocks have become appealing in the past year as these issues receded to attractive valuations from lofty levels reached during the late 1990s/early 2000s.

Blue Chip: The Blue Chip Portfolio passively tracks the direction of the large capitalization equity market and so would be expected to offer performance similar to that of the largest stocks in the domestic large-cap segment. It produced a total return of 2.29% for the year, compared to 4.91% for the S&P 500. The Portfolio lagged the broad-market S&P 500 largely because the benchmark’s smaller capitalization names drove performance for the period. Otherwise, the Portfolio’s performance compared quite favorably to that of the benchmark’s largest components. The Portfolio remains 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.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

Comparison of Change in Value of $10,000 Investment in

the High Grade Bond Portfolio and Lehman Brothers U.S. Aggregate Index

During the twelve-month period ended December 31, 2005, the High Grade Bond Portfolio outperformed the Lehman Brothers U.S. Aggregate Index (“Aggregate Index”), as reflected by the 2.65% total return produced by the Portfolio versus the 2.43% total return produced by the Index.

The total returns for the major components of the Aggregate Index for this period were as follows: U.S. Fixed Rate Mortgage Backed Securities (35% of the Index), 2.61%; U.S. Treasury Securities (25% of the Index), 2.79%; U.S. Investment Grade Corporate Securities (19% of the Index), 1.68%. In comparison, the Portfolio had approximately 41% of its assets invested in fixed rate mortgage-backed securities, 30% in corporate securities, 14% in cash equivalents, 9% in U.S. Agencies, and 6% in U.S. Treasuries. The Aggregate Index had an effective duration¹ of 4.57 as of December 31, 2005. The effective duration of the Portfolio was 3.85. The Portfolio outperformed the Aggregate Index mainly because of the Portfolio’s overexposure to outperforming cash equivalents, as well as specific issues in the Portfolio which more than offset our higher exposure to underperforming fixed rate mortgage backed and corporate issues.

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 cash equivalents and a slight increase in U.S. Agencies. 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.

Comparison of Change in Value of $10,000 Investment in

the Strategic Yield Portfolio and Lehman Brothers U.S. Credit/High Yield Index

During the twelve-month period ended December 31, 2005, the 3.26% total return produced by the Strategic Yield Portfolio was greater than the 2.18% 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 (76% of the Index), 1.96%; and U.S. High Yield (24% of the Index), 2.74%. In comparison, the Portfolio had approximately 31% of its assets invested in corporate securities rated investment grade by both Moody’s and Standard & Poor’s, 38% of its assets invested in corporate securities rated as non-investment grade or high yield by Moody’s and/or Standard & Poor’s, 20% of its assets invested in cash equivalents and 11% in U.S. Government Agency issues. The Portfolio outperformed the overall Lehman Brothers U.S. Credit/High Yield Index due to its larger exposure to outperforming cash equivalents and the general outperformance of individual securities in the Portfolio which more than offset expenses.

The Portfolio has historically invested in a mix of high yield and investment grade issues attempting to find attractive issues in both markets.

Comparison of Change in Value of $10,000 Investment in

the Managed Portfolio and S&P 500

The Managed Portfolio narrowly underperformed the S&P 500 for the twelve-month period ended December 31, 2005, with a total return of 4.53% compared to 4.91% for the Index. Given that the Portfolio holds not only equities but also fixed-income securities and cash instruments, its performance will generally differ from that of the S&P 500 from year to year. As such, the Portfolio modestly lagged the S&P 500 in 2005 primarily due to its fixed-income and cash allocations, both of which trailed the benchmark for the year; the Portfolio’s equities otherwise performed in line with the S&P 500.

Within the Portfolio’s equity allocation, we continue to emphasize high quality stocks and sectors, selecting names with a decidedly value or yield-oriented tilt. During the year, we were quite active in adding large- and mega-cap stocks such as Wal-Mart and Deere & Co., as well as adding to existing positions in Pfizer and Johnson & Johnson. We are finding that this segment of the equity market currently offers the most value, as many such stocks have traded down to historically attractive valuations from the lofty levels they reached in the late 1990s.

Because high quality fixed-income issues continue to trade near historically low yields, we remain more compelled to add to the Portfolio’s equity holdings than to its fixed-income allocation. At the same time, cash instruments will potentially offer competitive returns in the near-term.

* Returns shown do not reflect the deduction of taxes that a shareholder may pay on fund distributions or the redemption of fund shares.

Comparison of Change in Value of $10,000 Investment in

the Value Growth Portfolio and S&P 500

The Value Growth Portfolio outperformed the S&P 500 for the twelve-month period ended December 31, 2005; it produced a total return of 6.41% and the benchmark returned 4.91%. The Portfolio outperformed the S&P 500 primarily due to the positive relative performance of its energy and consumer discretionary holdings. Rising energy prices and energy company earnings drove energy stocks for the year and made that sector the S&P 500’s top performer. Relative to the S&P 500, the Portfolio was overweight in the energy sector much of the year, and its holdings outperformed the S&P 500’s energy constituents. The Portfolio remained underweight in the consumer discretionary sector for the year, and its holdings also performed better than did the S&P 500’s consumer discretionary stocks.

The Portfolio’s strong relative performance in these two sectors was partially offset by relative underperformance in the financials and materials sectors. It was underweight in the financials sector compared to the benchmark, and its financials holdings, in aggregate, lagged the S&P 500’s financials constituents. The Portfolio was overweight in the materials sector, and the performance of its holdings lagged that of the S&P 500’s materials sector constituents.

During 2005, we added new positions in stocks like Wal-Mart and Coca-Cola Enterprises, and also added to existing positions in Cisco and Microsoft. These and other stocks like them in the large- and mega-cap segment of the equity market currently appear to offer the most value across the aggregate equity market. Valuation has become attractive among such companies in the past five years because they have continued to grow earnings while their stock performance has actually been relatively flat. We continue to watch for opportunities to raise the Portfolio’s exposure to this segment of the equity market.

Comparison of Change in Value of $10,000 Investment in

the Blue Chip Portfolio and S&P 500

The Blue Chip Portfolio is designed to represent the large-capitalization sector of the domestic equity market, and remains substantially invested in approximately 50 such common stock issues. Given the Portfolio’s constitution, its performance will track with that of the broad-market S&P 500, but it will be most similar to that of the large-capitalization segment within the S&P 500.

The Portfolio posted a total return of 2.29% for the twelve-month period ended December 31, 2005, compared to 4.91% for the S&P 500. As has been common in the past several years, the benchmark’s smaller-capitalization components drove its overall performance for the year, while the returns from the benchmark’s largest members generally trailed those of the smaller members. Because the Portfolio holds only large-capitalization stocks, its gain approximated that of the S&P 500’s large-cap segment but trailed the S&P 500 overall.

Expense Example:

As a shareholder of the Fund, you incur ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in a given Portfolio of the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested on July 1, 2005 and held until December 31, 2005.

Actual Expenses –

The first line for each Portfolio in the table below provides information about actual account values and actual expenses for that Portfolio. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” for the same Portfolio to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes –

The second line for each Portfolio in the table below provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of that Portfolio and an assumed rate of return of 5% per year before expenses, which is not the actual return of the Portfolio. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in a given Portfolio of the Fund with other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

EQUITRUST VARIABLE INSURANCE SERIES FUND

NOTES TO FINANCIAL STATEMENTS

December 31, 2005

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, or mutual fund. The Fund is authorized to issue an unlimited number of shares of beneficial interest with no par value. 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. 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. In situations where market quotations are not readily available or quoted market prices are not reliable, investments are valued at fair value in accordance with the procedures adopted 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 value.

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 and Strategic Yield 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 Money Market Portfolio, each day the net asset value per share is calculated, net investment income and any realized gains and losses from investment transactions 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 U.S. generally accepted accounting principles. These differences are primarily due to differing treatments for certain basis adjustments resulting from a taxable spin-off and taxable mergers. Permanent book and tax basis differences are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification.

Dividends and distributions which exceed current and accumulated earnings and profits for federal income tax purposes are reported as return of capital distributions.

NOTES TO FINANCIAL STATEMENTS (continued)

1. Significant Accounting Policies (continued)

Use of Estimates

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

Indemnifications

Under the Fund’s organizational documents, its present and past officers and trustees are indemnified against certain liability arising out of the performance of their duties to the Fund. At the discretion of the Board of Trustees, employees and agents may also be indemnified. In addition, in the normal course of business the Fund enters into contracts that contain a variety of representations and warranties which provide general indemnifications. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred.

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, 2005, the following Portfolios had approximate net capital loss carryforwards set forth below:

	Portfolio
Net Capital Loss Carryforwards Expire In:	Value Growth		Strategic Yield		Blue Chip
2008	$	977,000	$	—	$	—
2010		—		1,689,000		1,786,000
2011		—		571,000		4,672,000
2012		—		—		556,000
2013		—		—		60,000
	$	977,000	$	2,260,000	$	7,074,000

During 2005, the Value Growth and Strategic Yield Portfolios utilized approximately $5,415,000 and $2,000 of capital loss carryforwards, respectively.

As of December 31, 2005, the Strategic Yield Portfolio had post-October capital losses of $98 that were deferred to the first day of the next fiscal year.

2. Federal Income Taxes (continued)

As of December 31, 2005, the components of accumulated earnings and capital gains (losses) on a tax basis were identical to those reported in the statements of assets and liabilities, except as follows:

	Portfolio
	Value Growth			Managed
Undistributed ordinary income	$	836,213		$	1,977,143
Accumulated capital gains (losses)		(976,836	)		4,643,149
Net unrealized appreciation of investments		5,185,523			8,019,617
Total accumulated earnings	$	5,044,900		$	14,639,909

Differences between book and tax amounts are primarily attributable to taxable spin-offs, mergers and corporate inversions.

3. Management Contract and Transactions with Affiliates

The Fund has entered into agreements with EquiTrust Investment Management Services, Inc. (“EquiTrust Investment”) relating to the management of the Portfolios and the investment of their assets. Pursuant to these agreements, fees paid to EquiTrust Investment are as follows: (1) annual investment advisory and management fees, which are based on each portfolio’s average daily net assets as follows: Value Growth Portfolio — 0.45%; High Grade Bond Portfolio — 0.30%; Strategic Yield Portfolio — 0.45%; Managed Portfolio — 0.45%; Money Market Portfolio — 0.25%; and Blue Chip Portfolio — 0.20%, and (2) accounting fees, which are based on each Portfolio’s daily net assets at an annual rate of 0.05%, with a maximum per Portfolio annual expense of $30,000.

The Fund entered into an agreement with EquiTrust Investment whereby EquiTrust Investment also serves as the Fund’s shareholder service, transfer and dividend disbursing agent. EquiTrust Marketing Services, LLC serves as the principal underwriter and distributor. There are no fees paid by the Fund associated with these services.

EquiTrust Investment has agreed to reimburse the Portfolios annually for total expenses (excluding brokerage, interest, taxes and extraordinary expenses) in excess of 1.50% of each Portfolio’s average daily net assets. The amount reimbursed, however, shall not exceed the amount of the investment advisory and management fee paid by the Portfolio for such period. During the year ended December 31, 2005, EquiTrust Investment further agreed to reimburse any Portfolio, to the extent that annual operating expenses, including the investment advisory fee, exceed 0.65%. For the year ended December 31, 2005, no expense reimbursements were made to the Fund by EquiTrust Investment.

Certain officers and trustees of the Fund are also officers of EquiTrust Investment, Farm Bureau Life Insurance Company and other affiliated entities. As of December 31, 2005, the total number of the shares of each Portfolio owned by Farm Bureau Life Insurance Company, EquiTrust Life Insurance Company and related separate accounts were as follows:

Portfolio	Shares
Value Growth	4,335,512
High Grade Bond	3,218,091
Strategic Yield	3,685,454
Managed	5,101,212

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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, 2005, 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 the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian. 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, 2005, 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 U.S. generally accepted accounting principles.

APPROVAL OF THE INVESTMENT ADVISORY CONTRACT

On November 17, 2005 the Board of Trustees, including a majority of the trustees who are not parties to or “interested persons” of either party to the investment advisory contract (the “independent trustees”), approved for continuance the Investment Advisory and Management Services Agreement dated April 6, 1987, as amended August 21, 1996, May 1, 1997 and May 21, 2003 (the “Agreement”) between EquiTrust Variable Insurance Series Fund (the “Fund”) and EquiTrust Investment Management Services, Inc. (the “Adviser”).

The Board of Trustees, including a majority of the independent trustees, determined that approval of the Agreement was in the best interests of the Fund. The independent trustees were assisted by independent legal counsel in making their determination.

The Board noted that the Adviser has managed each Portfolio since its inception. The Board recognizes that a long-term relationship with a capable, conscientious investment adviser is in the best interests of shareholders and that shareholders have invested in the Portfolios knowing that the Adviser managed the Portfolios and knowing the investment advisory fee schedule.

Nature, Quality and Extent of Services. With respect to the nature, quality and extent of the services provided by the Adviser to the Portfolios, the Board considered the functions performed by the Adviser and the personnel providing such services, the Adviser’s financial condition and the compliance regime created by the Adviser, including the fact that the Fund has had no material compliance issues.

The Board also reviewed and discussed reports prepared by the Adviser containing information on each Portfolio’s total returns and average annual total returns over various periods of time as compared to relevant market indices and a peer group of funds pursuing broadly similar strategies. The Board also considered for each Portfolio, with the exception of the Money Market Portfolio, the Portfolio’s Morningstar rating. The Board concluded that as to each Portfolio, the investment performance was satisfactory, and in some cases, good versus relevant market indices, and was in line with the other mutual funds included in the reports. Based on the information provided, the Board concluded that the nature and extent of services provided to each Portfolio were appropriate and that the quality was good.

Fees and Expenses. For each Portfolio, the Board compared the amounts paid to the Adviser for advisory services and each Portfolio’s expense ratio with other registered funds pursuing broadly similar strategies as included in reports prepared by the Adviser. This information showed that, with the exception of the High Grade Bond Portfolio, the advisory fee of each Portfolio was below average compared to other mutual funds pursuing broadly similar strategies. This information also showed that the expense ratio for each Portfolio was below average compared to similar mutual funds. In addition, the Board considered amounts paid to the Adviser by other EquiTrust funds. The Board received information from the Adviser regarding the Adviser’s standard advisory fee schedules for the Adviser’s other clients. With respect to the Adviser’s other clients, the Board considered that the mix of services provided and the level of responsibility required under the Agreement with the Fund were different than the Adviser’s obligations for similar client accounts and that the advisory fees of such accounts are less relevant to the Board’s consideration because they reflect different competitive forces than those in the mutual fund marketplace. With respect to other EquiTrust funds, the Board considered differences in fund and fee structures in light of the different distribution channels of the funds. Based on the information considered, the Board concluded that each Portfolio’s advisory fee was reasonable and appropriate in amount given the quality of services provided.

Profitability. With respect to the costs of services provided and profits realized by the Adviser, the Board considered the advisory fees received by the Adviser from each Portfolio, and requested and received from the Adviser information on each Portfolio’s net assets and expense ratios over a ten-year period. The Board also considered the fact that the Adviser continues to be subject to an expense reimbursement agreement and that the Adviser has kept expenses at a reasonable level. Based on this information, the Board concluded for each Portfolio that the Adviser’s profitability was not unreasonable.

Economies of Scale. The Board considered the extent to which economies of scale would be realized as each Portfolio grows and whether fee levels reflect economies of scale for the benefit of Portfolio shareholders. The Board reviewed each Portfolio’s net assets and expense ratios over a ten-year period. The Board noted that the High Grade Bond, Strategic Yield and Value Growth Portfolios have advisory fee breakpoints designed to share economies of scale with shareholders. The Board also considered that the current size of each Portfolio does not lend itself to economies of scale. The Board concluded with respect to each of the Portfolios, that the total expense ratios were reasonable.

39

Other Benefits to the Adviser and its Affiliates. The Board considered the character and amount of other incidental benefits received by the Adviser and its affiliates from their relationship with the Fund, including fees received by the Adviser for accounting services, shareholder services, dividend disbursing and transfer agent services and fees received by an affiliate of the Adviser for distribution services. The Board also considered that the Adviser does not engage in soft dollar arrangements in connection with brokerage transactions for the Portfolios. The Board concluded that, taking into account these benefits, the Portfolios’ advisory fees were reasonable.

Based on all of the information considered and the conclusions reached, the Board determined to approve the Agreement. The Board of Trustees, including the independent trustees, did not identify any single factor or group of factors as all important or controlling and considered all factors together.
