FBL VARIABLE INSURANCE SERIES FUND
- --------------------------------------------------------------------------------
 
FBL Variable Insurance Series Fund (the "Fund") is an open-end, diversified
management investment company consisting of six Portfolios, each with its own
investment objectives and policies. For most purposes, each Portfolio operates
like a separate mutual fund issuing its own shares.
 
   
                             Value Growth Portfolio
                           High Grade Bond Portfolio
                           High Yield Bond Portfolio
                               Managed Portfolio
                             Money Market Portfolio
                              Blue Chip Portfolio
    
 
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.
 
THE HIGH YIELD BOND PORTFOLIO INVESTS PRIMARILY IN LOWER-RATED BONDS, COMMONLY
REFERRED TO AS "JUNK BONDS," WHICH ENTAIL DEFAULT AND OTHER RISKS GREATER THAN
THOSE ASSOCIATED WITH HIGHER-RATED SECURITIES. PURCHASERS SHOULD CAREFULLY
ASSESS THE RISKS ASSOCIATED WITH AN INVESTMENT IN THIS PORTFOLIO. SEE
"INVESTMENT OBJECTIVES AND POLICIES OF THE PORTFOLIOS--HIGH YIELD BOND
PORTFOLIO," P. 13 AND "PRINCIPAL RISK FACTORS--SPECIAL CONSIDERATIONS--HIGH
YIELD BONDS," P. 16.
 
AN INVESTMENT IN THE MONEY MARKET PORTFOLIO IS NEITHER INSURED NOR GUARANTEED BY
THE U.S. GOVERNMENT. THERE CAN BE NO ASSURANCE THAT THE MONEY MARKET PORTFOLIO
WILL BE ABLE TO MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.

                   SUMMARY
- --------------------------------------------------------------------------------
THE FUND
   
                       FBL Variable Insurance Series Fund (the "Fund") was
                       established as a Massachusetts Business Trust under a
                       Declaration of Trust dated November 3, 1986. The Fund is
                       an open-end, diversified management investment company
                       registered under the Investment Company Act of 1940 (the
                       "Investment Company Act"). It is a series-type investment
                       company consisting of the Value Growth Portfolio
                       (formerly known as Growth Common Stock Portfolio), High
                       Grade Bond Portfolio, High Yield Bond Portfolio, Managed
                       Portfolio, Money Market Portfolio and Blue Chip Portfolio
                       (individually, a "Portfolio"; collectively, the
                       "Portfolios"). The Board of Trustees of the Fund (the
                       "Board of Trustees") may provide for additional
                       Portfolios at any time.
    
                       Other than shares sold to Farm Bureau Life Insurance
                       Company to seed the Fund, shares of the Fund are offered
                       only to separate accounts of certain life insurance
                       companies ("Participating Insurance Companies") to fund
                       variable annuity contracts ("VA contracts") and variable
                       life insurance policies ("VLI policies") issued by such
                       life insurance companies. The Fund currently does not
                       foresee any disadvantages to the holders of VA contracts
                       and VLI policies arising from the fact that the interests
                       of the holders of such contracts and policies may differ.
                       Nevertheless, the Board of Trustees intends to monitor
                       events in order to identify any material irreconcilable
                       conflicts that possibly may arise and to determine what
                       action, if any, should be taken in response to those
                       events or conflicts. Farm Bureau Life Insurance Company
                       will purchase shares of the Fund to serve as the
                       underlying investment for VLI policies and VA contracts.
                       The VA contracts and VLI policies are described in the
                       separate prospectuses for the contracts and policies
                       issued by the Participating Insurance Companies. The Fund
                       assumes no responsibility for such prospectuses.
 
                       Individual VA contract holders and VLI policyowners are
                       not "shareholders" of the Fund. Rather, the Participating
                       Insurance Companies and their separate accounts are the
                       shareholders (the "Shareholders"), although such
                       companies pass through voting rights to their VA contract
                       holders and VLI policyowners. The interest of a contract
                       holder or policyowner in the Fund is described in his or
                       her VA contract or VLI policy and in the current
                       prospectus for such contract or policy.

INVESTMENT OBJECTIVES
                       The Fund currently offers a choice of six investment
                       Portfolios, having the following investment objectives:
   
                        VALUE GROWTH PORTFOLIO.  This Portfolio seeks long-term
                        capital appreciation. The Portfolio pursues this
                       objective by investing primarily in equity securities of
                       companies that the investment adviser believes have a
                       potential to earn a high return on capital and/or in
                       equity securities that the investment adviser believes
                       are undervalued by the market place. Such equity
                       securities may include common stock, preferred stock and
                       securities convertible or exchangeable into common stock.
    
 
   
                        HIGH GRADE BOND PORTFOLIO.  This Portfolio seeks as high
                        a level of current income as is consistent with
                       investment in a high grade portfolio of debt securities.
                       The Portfolio pursues this objective by investing
                       primarily in debt securities rated AAA, AA or A by
                       Standard & Poor's Corporation or Aaa, Aa or A by Moody's
                       Investors Service, Inc. and in debt securities issued or
                       guaranteed by the U.S. Government or its agencies or
                       instrumentalities.
    
 
                        HIGH YIELD BOND PORTFOLIO.  This Portfolio seeks, as a
                        primary objective, as high a level of current income as
                       is consistent with investment in a portfolio of
                       fixed-income securities rated in the lower categories of
                       established rating services. As a secondary objective,
                       the Portfolio seeks capital appreciation when consistent
                       with its primary objective. The Portfolio pursues these
                       objectives by investing primarily in fixed-income
                       securities rated Baa or lower by Moody's Investors
                       Service, Inc. and/or BBB or
 
                                       3

                       lower by Standard & Poor's Corporation, or unrated
                       securities of comparable quality. AN INVESTMENT IN THIS
                       PORTFOLIO MAY ENTAIL GREATER THAN ORDINARY FINANCIAL
                       RISK.
 
   
                        MANAGED PORTFOLIO.  This Portfolio seeks the highest
                        total investment return of income and capital
                       appreciation. The Portfolio will pursue this objective
                       through a fully managed investment policy consisting of
                       investment in the following three market sectors: (i)
                       growth common stocks and securities convertible or
                       exchangeable into growth common stocks, including
                       warrants and rights; (ii) high grade debt securities and
                       preferred stocks of the type in which the High Grade Bond
                       Portfolio may invest; and (iii) high quality short-term
                       money market instruments of the type in which the Money
                       Market Portfolio may invest.
    
 
                        MONEY MARKET PORTFOLIO.  This Portfolio seeks maximum
                        current income consistent with liquidity and stability
                       of principal. The Portfolio will pursue this objective by
                       investing in high quality short-term money market
                       instruments. AN INVESTMENT IN THE MONEY MARKET PORTFOLIO
                       IS NEITHER INSURED NOR GUARANTEED BY THE U.S. GOVERNMENT.
                       THERE CAN BE NO ASSURANCE THAT THE MONEY MARKET PORTFOLIO
                       WILL BE ABLE TO MAINTAIN A STABLE NET ASSET VALUE OF
                       $1.00 PER SHARE.
 
                        BLUE CHIP PORTFOLIO.  This Portfolio seeks growth of
                        capital and income. The Portfolio pursues this objective
                       by investing primarily in common stocks of
                       well-capitalized, established companies. Because this
                       Portfolio may be invested heavily in particular stocks or
                       industries, an investment in this Portfolio may entail
                       relatively greater risk of loss.
 
   
                       There can be no assurance that the objectives of any
                       Portfolio will be realized. During periods when the
                       Adviser believes that the equity market is overvalued, or
                       when warranted by other prevailing market or economic
                       conditions, the Value Growth Portfolio may hold
                       substantial amounts of non-equity investments. For
                       further information regarding the investment practices of
                       the Portfolios, see "Investment Objectives and Policies
                       of the Portfolios." For further information regarding the
                       principal risk factors associated with investment in any
                       of the Fund's Portfolios, see "Principal Risk Factors."

                   INVESTMENT OBJECTIVES AND POLICIES OF THE PORTFOLIOS
- --------------------------------------------------------------------------------
 
                       Each Portfolio of the Fund has distinct investment
                       objectives which it pursues through separate investment
                       policies as described below. There can be no assurance
                       that the objectives of any Portfolio will be achieved.
                       The differences in objectives and policies among the
                       Portfolios can be expected to affect the return of each
                       Portfolio and the degree of market and financial risk to
                       which each Portfolio is subject.
 
                       The Statement of Additional Information contains specific
                       investment restrictions which govern the Portfolios'
                       investments. Those restrictions which are identified as
                       fundamental policies, as well as the investment
                       objectives and investment policies of each Portfolio
                       described below in the first paragraph for each Portfolio
                       are fundamental policies, and may not be changed without
                       a majority vote of the outstanding shares of the affected
                       Portfolio. See "General Information--Shareholder Voting
                       Rights." All other investment policies and practices
                       described in this Prospectus and in the Statement of
                       Additional Information are not fundamental and may be
                       changed by the Board of Trustees without approval of the
                       Shareholders. Each of the Portfolios may engage in
                       certain of the portfolio strategies described in this
                       Prospectus under "Description of Certain Investment
                       Techniques" and in the Statement of Additional
                       Information. "Appendix C -- Description of Corporate Bond
                       Ratings" describes the ratings of Moody's Investors
                       Service, Inc. ("Moody's") and Standard & Poor's
                       Corporation ("Standard & Poor's") that are referred to
                       herein.
 
                       The portfolio turnover rates for the Portfolios are set
                       forth under "Financial Highlights." Portfolio turnover is
                       calculated by dividing the lesser of purchases or sales
                       of a Portfolio's securities during a fiscal year by the
                       average monthly value of the Portfolio's securities
                       during such fiscal year. In determining the portfolio
                       turnover rate, all securities whose maturities or
                       expiration dates at the time of acquisition were one year
                       or less are excluded. Thus, the portfolio turnover rate
                       measures only that portion of the Portfolio that is
                       considered to be long-term. Portfolio turnover rates may
                       be affected by factors such as purchase and redemption
                       requirements and market volatility and may vary greatly
                       from time to time. Frequency of portfolio turnover will
                       not be a limiting factor if the investment adviser deems
                       it desirable to purchase or sell securities. Increased
                       portfolio turnover may result in greater brokerage
                       commissions and consequent expense to the Portfolio. If
                       any Portfolio were to derive more than 30% of its gross
                       income from the sale of securities held less than three
                       months, it might fail to qualify under the tax laws as a
                       regulated investment company for that year and
                       consequently would lose certain beneficial tax treatment
                       of its income; however, each Portfolio intends to
                       continue to qualify as a regulated investment company
                       each year. See "Taxes and Distributions."
 
                       Following is a description of the investment objectives
                       and certain of the investment practices of each of the
                       Fund's Portfolios. For a further description of the
                       investment practices of the various Portfolios, see
                       "Description of Certain Investment Techniques."

                       appreciation. The Portfolio pursues its investment
                       objective by investing primarily in equity securities of
                       companies that the investment adviser believes have a
                       potential to earn a high return on capital and/or in
                       equity securities that the investment adviser believes
                       are undervalued by the market place. Such equity
                       securities may include common stock, preferred stock and
                       securities convertible or exchangeable into common stock.
    
   
                       The Value Growth Portfolio may invest in securities of
                       companies in cyclical industries during periods when such
                       securities appear to the investment adviser to have
                       strong potential for capital appreciation. The Portfolio
                       may also invest in "special situation" companies. A
                       "special situation" company is one that, in the opinion
                       of the Fund's

                       investment adviser, has potential for significant future
                       earnings growth but has not performed well in the recent
                       past. These situations may include companies with
                       management turnaround, corporate or asset restructuring
                       or significantly undervalued assets.
    
 
   
                       The investment adviser's strategy for the Value Growth
                       Portfolio is based upon a value-oriented analysis of
                       common stocks. Such an analysis focuses upon evaluations
                       of key financial ratios such as stock price-to-book
                       value, stock price-to-earnings, stock price-to-cash flow
                       and debt-to-total capital. The investment adviser
                       attempts to determine the fundamental value of an
                       enterprise using the foregoing ratios and by evaluating
                       an enterprise's balance sheet (e.g., comparing the
                       enterprise's assets with the purchase price of similar
                       recently acquired assets) as well as by using dividend
                       discounting models.
    
 
   
                       The investment adviser's emphasis on fundamental analysis
                       of each company's prospects and the inherent value of its
                       securities may result in a portion of the Portfolio being
                       invested in medium- or smaller-sized companies that are
                       less readily identifiable than larger, better-known
                       companies or in companies that are not perceived as being
                       popular investments at a given time. The Adviser believes
                       that opportunities can be found at all size levels and,
                       therefore, the Portfolio may invest in companies of all
                       sizes.
    
 
   
                       When warranted, in the opinion of the investment adviser,
                       by prevailing market or economic conditions, the
                       Portfolio, for temporary defensive purposes, may invest
                       up to 100% of its assets in other types of securities,
                       including investment-grade commercial paper, corporate
                       bonds, debentures, preferred stocks, obligations of banks
                       and savings institutions, U.S. Government securities,
                       government agency securities and repurchase agreements,
                       or it may retain funds in cash. "Investment-grade
                       commercial paper" is commercial paper rated A-2 or better
                       by Standard & Poor's or Prime-2 or better by Moody's.
    
 
                       Through careful selection of individual securities,
                       diversification of investments by industry and by type of
                       security and constant supervision of the investment
                       portfolio, the investment adviser strives to reduce risk
                       and thereby conserve principal. However, the Portfolio's
                       investments are subject to market fluctuations and the
                       risks inherent in all securities, and thus there can be
                       no assurance that its investment objectives will be
                       achieved.

HIGH GRADE BOND
PORTFOLIO
   
                       The investment objective of the High Grade Bond Portfolio
                       is to provide as high a level of current income as is
                       consistent with investment in a high grade portfolio of
                       debt securities. The Portfolio pursues its objective by
                       investing primarily in debt securities rated AAA, AA or A
                       by Standard & Poor's or Aaa, Aa or A by Moody's and in
                       U.S. Government securities and government agency
                       securities.
    
                       From time to time, up to 20% of the Portfolio's assets
                       may be invested in unrated debt securities or debt
                       securities which are not rated within the three highest
                       grades of Standard & Poor's or Moody's as described above
                       or in convertible debt securities, convertible preferred
                       stocks and nonconvertible preferred stocks rated within
                       the three highest grades of Standard & Poor's or Moody's
                       applicable to such securities. To the extent that the
                       Portfolio does invest in debt securities that are rated
                       lower than A by Moody's or Standard & Poor's (or are
                       unrated but equivalent in quality to such securities),
                       the Fund's investment portfolio will be subject to
                       relatively greater risk of loss of income and principal
                       as discussed under "Principal Risk Factors--Special
                       Considerations--High Yield Bonds." Securities rated Baa
                       or lower by Moody's and BBB or lower by Standard & Poor's
                       are considered by those rating agencies to have varying
                       degrees of speculative characteristics. Consequently,
                       although they can be expected to provide higher yields,
                       such securities may be subject to greater market
                       fluctuations and risk of loss of income and principal
                       than lower-yielding, higher-rated fixed-income
                       securities. It is intended that at least 65% of the
                       Portfolio's total assets will be invested in medium- and
                       long-term debt securities that are rated A or better or
                       that are unrated but of equivalent quality.

                       The Portfolio will not directly purchase common stocks.
                       However, it may retain up to 10% of the value of its
                       assets in common stocks acquired either by conversion of
                       debt securities or by the exercise of warrants attached
                       to debt securities.
 
                       When warranted, in the opinion of the investment adviser,
                       by prevailing market or economic conditions, the
                       Portfolio for temporary defensive purposes may invest up
                       to 100% of its assets in other types of securities,
                       including investment-grade commercial paper, obligations
                       of banks and savings institutions, U.S. Government
                       securities, government agency securities and repurchase
                       agreements, or it may retain funds in cash.
 
                       Although in the opinion of the Fund's investment adviser,
                       the risk of loss of principal should be minimized by the
                       quality of the investments in which the Portfolio will
                       invest primarily, the long maturities that typically
                       provide the best yields may subject the Portfolio to
                       substantial price changes resulting from market yield
                       fluctuations. The market price of fixed-income securities
                       such as those purchased by the Portfolio is affected by
                       changes in interest rates; generally, the market value of
                       fixed income securities will fall as interest rates rise,
                       and will rise as interest rates fall. There can be no
                       assurance that the Portfolio will achieve its objective.

HIGH YIELD BOND
PORTFOLIO
   
                       The primary investment objective of the High Yield Bond
                       Portfolio is to obtain as high a level of current income
                       as is consistent with investment in a portfolio of fixed-
                       income securities rated in the lower categories of
                       established rating services. As a secondary objective,
                       the Portfolio seeks capital appreciation when consistent
                       with its primary objective. The Portfolio pursues its
                       investment objectives by investing primarily in
                       fixed-income securities, including corporate bonds and
                       notes, convertible debt securities and preferred stocks
                       that are rated in the lower categories of established
                       rating services (Ba or lower by Moody's and BB or lower
                       by Standard & Poor's), or in unrated securities of
                       comparable quality. Such securities are commonly known as
                       "junk bonds."
    
                       Securities rated Ba or lower by Moody's and BB or lower
                       by Standard & Poor's are considered by those rating
                       services to have varying degrees of speculative
                       characteristics. Consequently, although they can be
                       expected to provide higher yields, such securities may be
                       subject to greater market fluctuations and risk of loss
                       of income and principal than lower-yielding,
                       higher-rated, fixed-income securities. See "Principal
                       Risk Factors -- Special Considerations -- High Yield
                       Bonds" for a discussion of various risk factors relating
                       to high yield bonds. The investment adviser will not rely
                       solely on the ratings assigned by the rating services,
                       and the Portfolio may invest, without limit, in unrated
                       securities if such securities offer, in the opinion of
                       the investment adviser, a relatively high yield without
                       undue risk. Although the Portfolio will invest primarily
                       in lower-rated securities, it will not invest in
                       securities in the lowest rating categories (Ca or lower
                       for Moody's and CC or lower for Standard & Poor's) unless
                       the investment adviser believes that the financial
                       condition of the issuer or the protection afforded to the
                       particular securities is stronger than would otherwise be
                       indicated by such low ratings.
 
                       The Portfolio anticipates that under normal circumstances
                       more than 80% of its assets will be invested in
                       fixed-income securities, including convertible and
                       non-convertible debt securities and preferred stock, and
                       that at least 65% of its assets will be invested in debt
                       securities. The remaining assets of the Portfolio may be
                       held in cash or investment-grade commercial paper,
                       obligations of banks and savings institutions, U.S.
                       Government securities, government agency securities and
                       repurchase agreements. The Portfolio does not intend to
                       invest in common stocks, rights or other equity
                       securities, but it may acquire or hold such securities
                       (if consistent with its objectives) when they are
                       acquired in unit offerings with fixed-income securities
                       or in connection with an actual or proposed conversion or
                       exchange of fixed-income securities.
 
                       When changing economic conditions and other factors cause
                       the yield difference between lower-rated and higher-rated
                       securities to narrow, the Portfolio may
 
                                       13
<PAGE>
                       purchase higher-rated securities if the investment
                       adviser believes that the risk of loss of income and
                       principal may be substantially reduced with only a
                       relatively small reduction in yield. In addition, when
                       warranted, in the opinion of the investment adviser, by
                       prevailing market or economic conditions, the Portfolio
                       for temporary defensive purposes may invest up to 100% of
                       its assets in other types of securities, including
                       investment-grade commercial paper, obligations of banks
                       and savings institutions, U.S. Government securities,
                       government agency securities and repurchase agreements,
                       or it may retain funds in cash. The yield on such
                       securities may be lower than the yield on lower-rated
                       fixed-income securities.
 
                       Because an investment in high-yield securities entails
                       relatively greater risk of loss of income and principal,
                       an investment in the Portfolio may not constitute a
                       complete investment program and may not be appropriate
                       for all investors. There can be no assurance that the
                       Portfolio will achieve its objectives.
- --------------------------------------------------------------------------------
MANAGED PORTFOLIO
   
                       This Portfolio seeks the highest total investment return
                       of income and capital appreciation. The Portfolio pursues
                       this objective through a fully managed investment policy
                       consisting of investment in the following three market
                       sectors: (i) growth common stocks and securities
                       convertible or exchangeable into growth common stocks,
                       including warrants and rights; (ii) high grade debt
                       securities and preferred stocks of the type in which the
                       High Grade Bond portfolio may invest; and (iii) high
                       quality short-term money market instruments of the type
                       in which the Money Market Portfolio may invest.
    
   
                       The Portfolio's investment policy for the stock market
                       sector is to invest in those securities that appear to
                       the investment adviser to possess above average potential
                       for appreciation in market value, usually as a result of
                       the issuer's relatively favorable prospects for
                       improvement in earnings, which generally include those of
                       companies with established records of growth in sales or
                       earnings, and companies with promising new products,
                       services or processes. The Portfolio's investment
                       policies for the debt and money market sectors are
                       substantially identical to those of the High Grade Bond
                       Portfolio and Money Market Portfolio, respectively. The
                       Managed Portfolio will, from time to time, adjust the mix
                       of investments among the three market sectors to
                       capitalize on perceived variations in return potential
                       produced by the interaction of changing financial markets
                       and economic conditions. There are no restrictions as to
                       the proportion of one or another type of security which
                       the Portfolio may hold. Accordingly, the Portfolio may,
                       at any given time, be substantially invested in equity
                       securities, in high grade debt securities or in high
                       quality short-term money market instruments. Major
                       changes in the investment mix may occur over several
                       years or during a single year or shorter period depending
                       upon market and economic conditions. The fact that the
                       investment mix may be adjusted from time to time may
                       result in high portfolio turnover and, consequently, high
                       brokerage charges to the Portfolio.
    
 
                       Achieving the Portfolio's objective depends on the
                       investment adviser's ability to assess the effect of
                       economic and market trends on different sectors of the
                       market. There can be no assurance that the investment
                       objective of the Portfolio will be achieved.

MONEY MARKET
PORTFOLIO
                       The investment objective of the Money Market Portfolio is
                       to obtain maximum current income consistent with
                       liquidity and stability of principal. The Portfolio
                       pursues its objective by investing in high quality
                       short-term debt obligations denominated in U.S. dollars
                       that have been determined to present minimal credit risk.
                       Money market instruments which the Money Market Portfolio
                       may purchase include U.S. Government securities,
                       government agency securities, obligations of banks and
                       savings institutions, commercial paper, short-term
                       corporate debt securities and repurchase agreements.
                       Appendix A contains a more detailed description of the
                       money market instruments in which the Money Market
                       Portfolio may invest. The Portfolio's investments will be
                       limited to money market instruments which mature in
                       thirteen months or less from the date of purchase;
                       however, the Portfolio may invest in repurchase
                       agreements in which the underlying securities have
                       maturities in excess
                                       14
<PAGE>
                       of one year from the date of purchase. In addition, the
                       Portfolio limits its investments to securities that meet
                       the quality and diversification requirements of Rule 2a-7
                       under the Investment Company Act of 1940. See Appendix A.
                       The dollar weighted average portfolio maturity of the
                       Portfolio will not exceed 90 days. The Portfolio seeks to
                       maintain a constant net asset value of $1.00 per share,
                       and will use the amortized cost method of securities
                       valuation. See "Valuation of Portfolio Securities."
                       Because of the short-term nature of the investments of
                       this Portfolio, a portfolio turnover rate is not
                       applicable.
 
                       While the Money Market Portfolio strives to maintain a
                       stable net asset value, there can be no assurance that
                       the net asset value will remain stable at $1.00. An
                       investment in the Money Market Portfolio is neither
                       insured nor guaranteed by the U.S. Government.
- --------------------------------------------------------------------------------
BLUE CHIP PORTFOLIO
                       The investment objective of the Blue Chip Portfolio is
                       growth of capital and income. The Portfolio pursues its
                       objective by investing primarily in common stocks of
                       well-capitalized, established companies.
                       In pursuing its objective, the Portfolio will invest in
                       stocks of approximately 40 large, well-known companies
                       that the Fund's investment adviser believes to
                       collectively comprise a representative cross-section of
                       major industries. Companies of this type are commonly
                       referred to as "blue chip." Blue chip companies are
                       generally identified by their substantial capitalization,
                       established history of earnings and superior management
                       structure. The investment adviser will base its
                       determination of the companies to be included or retained
                       in the Portfolio, not on the basis of any analysis of the
                       companies' underlying economic or financial fundamentals
                       or of the relative value of the securities, but rather on
                       whether the companies in the Portfolio, taken together,
                       reasonably represent a cross-section of major industries.
                       The adviser anticipates that the Portfolio will purchase
                       approximately equal dollar amounts of shares of each
                       company. However, the Portfolio will not own positions of
                       equal value in the various companies, partly because of
                       price fluctuations after purchases by the Portfolio.
 
                       The Portfolio may, from time to time, have more than 5%
                       of the value of its total assets invested in each of one
                       or more particular companies. However, as to 75% of the
                       Portfolio's total assets, no more than 5% of the
                       Portfolio's total assets (at the time of purchase) will
                       be invested in securities of any one issuer (other than
                       the U.S. Government and its agencies and
                       instrumentalities). The concentration of a significant
                       portion of its assets in stocks of one or a few companies
                       (or in a relatively limited number of industries) may
                       subject the Portfolio to increased risk of loss if those
                       stocks (or stocks in those industries) were to decline in
                       value.
 
                       The Portfolio expects that it will remain substantially
                       invested in stocks at all times. However, at most times
                       the Portfolio will hold a small portion of its assets
                       (not to exceed 15% of its total assets) in cash or cash
                       equivalents to accommodate redemptions and so as to avoid
                       having to purchase stocks in small quantities and thereby
                       incur excessive brokerage costs. Any such cash balances
                       will be invested in high-quality short-term money market
                       instruments of the type in which the Money Market
                       Portfolio may invest, or retained in cash. The Portfolio
                       will not engage in the trading of securities for the
                       purpose of realizing short-term profits.

                   PRINCIPAL RISK FACTORS
- --------------------------------------------------------------------------------
 
                       In general, the risk associated with the investments of a
                       particular Portfolio can be described in terms of current
                       income volatility, financial risk and market risk.
                       Current income volatility refers to the degree and
                       rapidity with which changes in overall market interest
                       rates affect the level of current income. Financial risk
                       refers to the ability of an issuer of a debt security to
                       pay, on a timely basis, principal and interest on such
                       security. With respect to the issuer of an equity
                       security, financial risk refers to its earning stability
                       and overall financial soundness. Market risk refers to
                       the effect of
 
                                       15
<PAGE>
                       changes in the overall level of interest rates on the
                       price of debt securities. Generally, the current value of
                       debt securities varies inversely with changes in
                       prevailing interest rates; if interest rates rise, the
                       value of a debt security will tend to fall. Market risk
                       for equity securities refers to overall stock market
                       valuation levels.
 
   
                       The VALUE GROWTH PORTFOLIO and BLUE CHIP PORTFOLIO most
                       likely will be subject to moderate levels of both market
                       and financial risk.
    
 
                       The HIGH GRADE BOND PORTFOLIO most likely will be subject
                       to moderate levels of market risk and relatively low
                       levels of financial risk and current income volatility.
 
                       The HIGH YIELD BOND PORTFOLIO most likely will be subject
                       to relatively high levels of financial risk, moderate
                       levels of market risk and relatively low levels of
                       current income volatility.
 
                       The market value of fixed-income securities is affected
                       by changes in general market interest rates. If interest
                       rates decline, the market value of fixed-income
                       securities tends to increase, while if interest rates
                       increase, the market value of fixed-income securities
                       tends to decrease. Higher-rated fixed-income securities
                       tend to have lower interest rates and yields, and less
                       market or financial risk, than do lower-rated fixed-
                       income securities. Lower-rated and unrated securities are
                       generally subject to a greater degree of market and
                       financial risk than higher-rated securities, for reasons
                       including the greater possibility that issuers of
                       lower-rated or unrated securities may not be able to pay
                       the principal and interest due on such securities,
                       especially during periods of adverse economic conditions.
 
                       The MANAGED PORTFOLIO most likely will be subject to
                       moderate levels of market and financial risk and
                       relatively low levels of current income volatility,
                       although current income volatility could be higher if the
                       Portfolio is heavily invested in short-term money market
                       instruments.
 
                       The MONEY MARKET PORTFOLIO should be subject to little
                       market or financial risk because it invests in high
                       quality short-term investments that reflect current
                       market interest rates. Although these types of securities
                       generally are considered to have low financial risk,
                       there is some possibility that issuers may fail to meet
                       their principal and interest obligations on a timely
                       basis. The Portfolio could experience a high level of
                       current income volatility because the level of its
                       current income directly reflects short-term interest
                       rates.
- --------------------------------------------------------------------------------
SPECIAL
CONSIDERATIONS-- HIGH
YIELD BONDS
                       As reflected above, the High Yield Bond Portfolio intends
                       to invest a substantial portion of its assets in
                       fixed-income securities offering high current income.
                       Additionally, subject to its specific investment
                       objectives and policies as described above, the High
                       Grade Bond Portfolio may invest a portion of its assets
                       in such securities. Such high yielding fixed-income
                       securities are ordinarily in the lower rating categories
                       of Moody's or Standard & Poor's or will be unrated
                       securities of comparable quality. Such securities are
                       commonly known as "junk bonds." These lower-rated,
                       fixed-income securities are considered, on balance, as
                       predominantly speculative with respect to capacity to pay
                       interest and repay principal in accordance with the terms
                       of the obligation and will generally involve more credit
                       risk than securities in the higher rating categories. The
                       market values of such securities tend to reflect
                       individual corporate developments to a greater extent
                       than do higher-rated securities, which react primarily to
                       fluctuations in the general level of interest rates. Such
                       lower-rated securities also tend to be more sensitive to
                       economic conditions than are higher-rated securities.
                       Adverse publicity and investor perceptions, whether or
                       not based on fundamental analysis, regarding lower-rated
                       bonds may depress prices and liquidity for such
                       securities. Factors adversely affecting the market value
                       of high yielding securities will adversely affect a
                       Portfolio's net asset value. In addition, a Portfolio may
                       incur additional expenses to the extent it were required
                       to seek recovery upon a default in the payment of
                       principal or interest on its portfolio holdings. Although
                       some risk is inherent in all securities ownership,
                       holders of
                                       16
<PAGE>
                       fixed-income securities have a claim on the assets of the
                       issuer prior to the holders of common stock. Therefore,
                       an investment in fixed-income securities generally
                       entails less risk than an investment in common stock of
                       the same issuer.
 
                       The investment philosophy of the High Yield Bond
                       Portfolio with respect to high yield bonds is based on
                       the premise that over the long-term a broadly diversified
                       portfolio of high yield fixed-income securities should,
                       even taking into account possible losses, provide a
                       higher net return than that achievable on a portfolio of
                       higher-rated securities. The High Yield Bond Portfolio
                       seeks to achieve the highest yields possible while
                       reducing relative risks through:
 
                           (a) broad diversification;
 
                           (b) credit analysis by the investment adviser of the
                               issuers in which the Portfolio invests;
 
                           (c) monitoring and seeking to anticipate changes and
                               trends in the economy and financial markets that
                               might affect the prices of portfolio securities.
 
                       The investment adviser's judgment as to the
                       "reasonableness" of the risk involved in any particular
                       investment will be a function of its experience in
                       managing fixed-income investments and its evaluation of
                       general economic and financial conditions of a specific
                       issuer.
 
                       In some circumstances, defensive strategies may be
                       implemented to preserve or enhance capital even at the
                       sacrifice of current yield. Defensive strategies, which
                       may be used singly or in any combination, may include,
                       but are not limited to, investments in discount
                       securities or investments in money market instruments.
 
                       High yielding securities may be issued by corporations in
                       the growth stage of their development. They may also be
                       issued in connection with a corporate reorganization or
                       as part of a corporate takeover. Companies that issue
                       such high yielding securities are often highly leveraged
                       and may not have available to them more traditional
                       methods of financing. Therefore, the risk associated with
                       acquiring the securities of such issuers generally is
                       greater than is the case with higher-rated securities.
                       For example, during an economic downturn or a sustained
                       period of rising interest rates, highly leveraged issuers
                       of high yielding securities may experience financial
                       stress. During such periods, such issuers may not have
                       sufficient revenues to meet their interest payment
                       obligations. The issuer's ability to service its debt
                       obligations may also be adversely affected by specific
                       corporate developments, or the issuer's inability to meet
                       specific projected business forecasts, or the
                       unavailability of additional financing. The risk of loss
                       due to default by the issuer is significantly greater for
                       the holders of high yielding securities because such
                       securities are generally unsecured and are often
                       subordinated to other creditors of the issuer.
 
                       High yielding securities frequently have call or buy-back
                       features that would permit an issuer to call or
                       repurchase the security from the Portfolio. If a call
                       were exercised by the issuer during a period of declining
                       interest rates, a Portfolio would likely have to replace
                       such called security with a lower yielding security, thus
                       decreasing the net investment income to the Portfolio.
                       The premature disposition of a high yielding security
                       because of a call or buy-back feature, the deterioration
                       of the issuer's creditworthiness or a default may also
                       make it more difficult for a Portfolio to time its
                       receipt of income, which may have tax implications.
 
                       A Portfolio may have difficulty disposing of certain high
                       yielding securities for which there is a thin trading
                       market. Because not all dealers maintain markets in all
                       high yielding securities, there is no established retail
                       secondary market for many of these securities, and the
                       Fund anticipates that they could be sold only to a
                       limited number of dealers or institutional investors. To
                       the extent there is a secondary trading market for high
                       yielding securities, it is generally not so liquid as
                       that for higher-rated securities. The lack of a liquid
                       secondary market may have an adverse impact on market
                       price and a Portfolio's ability to dispose of particular
                       issues when necessary to meet the Portfolio's liquidity
                       needs or in response to a specific economic event such
 
                                       17
<PAGE>
                       as a deterioration in the creditworthiness of the issuer.
                       The lack of a liquid secondary market for certain
                       securities may also make it more difficult for the Fund
                       to obtain accurate market quotations for purposes of
                       valuing a Portfolio's assets. Market quotations are
                       generally available on many high yield issues only from a
                       limited number of dealers and may not necessarily
                       represent firm bids of such dealers or prices for actual
                       sales.
 
                       It is likely that a major economic recession could
                       severely affect the market for and the values of high
                       yielding securities, as well as the ability of the
                       issuers of such securities to repay principal and pay
                       interest thereon.
 
                       A Portfolio may acquire high yielding securities that are
                       sold without registration under the federal securities
                       laws and therefore carry restrictions on resale. While
                       many recent high yielding securities have been sold with
                       registration rights, covenants and penalty provisions for
                       delayed registration, if a Portfolio is required to sell
                       such restricted securities before the securities have
                       been registered, it may be deemed an underwriter of such
                       securities as defined in the Securities Act of 1933,
                       which entails special responsibilities and liabilities. A
                       Portfolio may incur special costs in disposing of such
                       securities, but will generally incur no costs when the
                       issuer is responsible for registering the securities.
 
                       A Portfolio may acquire high yielding securities during
                       an initial underwriting. Such securities involve special
                       risks because they are new issues. The Fund has no
                       arrangement with any person concerning the acquisition of
                       such securities and the investment adviser will carefully
                       review the credit and other characteristics pertinent to
                       such new issues.
 
                       From time to time, there have been proposals for
                       legislation designed to limit the use of certain high
                       yielding securities in connection with leveraged
                       buy-outs, mergers and acquisitions, or to limit the
                       deductibility of interest payments on such securities.
                       Such proposals, if enacted into law, could reduce the
                       market for such securities generally, could negatively
                       affect the financial condition of issuers of high yield
                       securities by removing or reducing a source of future
                       financing and could negatively affect the value of
                       specific high yield issues. However, the likelihood of
                       any such legislation or the effect thereof is uncertain.
 
                       Zero coupon securities and pay-in-kind bonds involve
                       additional special obligations. Zero coupon securities
                       are debt obligations that do not entitle the holder to
                       any periodic payments of interest prior to maturity or to
                       a specified cash payment date when the securities begin
                       paying current interest (the "cash payment date"), and
                       therefore are issued and traded at a discount from their
                       face amount or par value. The discount varies depending
                       upon the time remaining until maturity or cash payment
                       date, prevailing interest rates, liquidity of the
                       security and the perceived credit quality of the issuer.
                       The discount, absent financial difficulties of the
                       issuer, decreases as the final maturity or cash payment
                       date of the security approaches. The market prices of
                       zero coupon securities are generally more volatile than
                       those of securities that pay interest periodically, and
                       they are more likely to respond to changes in interest
                       rates than non-zero coupon securities having similar
                       maturities and credit quality. The credit risk factors
                       pertaining to lower-rated securities generally also apply
                       to lower-rated zero coupon bonds and pay-in-kind bonds.
                       Such zero coupon, pay-in-kind or delayed interest bonds
                       carry an additional risk in that, unlike bonds that pay
                       interest throughout the period to maturity, a Portfolio
                       will realize no cash until the cash payment date unless a
                       portion of such securities is sold and, if the issuer
                       defaults, a Portfolio may obtain no return at all on its
                       investment.
 
                       Current federal income tax law requires the holder of
                       zero coupon securities or of certain pay-in-kind bonds
                       (bonds that pay interest through the issuance of
                       additional bonds) to accrue income with respect to these
                       securities prior to the receipt of cash payments. To
                       maintain its qualification as a registered investment
                       company and avoid liability for federal income and excise
                       taxes, a Portfolio will be required to distribute
 
                                       18
<PAGE>
                       income accrued with respect to these securities and may
                       have to dispose of portfolio securities under
                       disadvantageous circumstances in order to generate cash
                       to satisfy these distribution requirements.

                       securities appears under "Appendix C -- Description of

                   DESCRIPTION OF CERTAIN INVESTMENT TECHNIQUES
- --------------------------------------------------------------------------------
 
                       Except as otherwise noted below, the following investment
                       strategies and techniques may be used by all Portfolios.
- --------------------------------------------------------------------------------
FOREIGN SECURITIES
   
                       The Value Growth Portfolio and Managed Portfolio each may
                       invest up to 25% of its net assets in equity and debt
                       securities of foreign issuers, and the High Grade Bond
                       Portfolio and High Yield Bond Portfolio each may invest
                       up to 25% of its net assets in debt securities of foreign
                       issuers, to the extent the purchase of such foreign
                       securities is otherwise consistent with the Portfolio's
                       investment objectives. Investments will be made only in
                       foreign securities which are publicly traded on U.S.
                       exchanges and payable in U.S. dollars. The investment
                       adviser will apply standards for evaluating quality and
                       risk of investments in foreign securities comparable to
                       those it applies to investments in domestic securities
                       while also taking into consideration the opportunities
                       and special risks in connection with foreign securities.
    
   
                       Investments in foreign securities can provide a Portfolio
                       with more opportunities for attractive returns, but they
                       may also involve some special risks such as exposure to
                       potentially adverse local political and economic
                       developments; nationalization and exchange controls;
                       potentially lower liquidity and high volatility; and
                       possible problems arising from accounting, disclosure,
                       settlement, and regulatory practices that differ from
                       U.S. standards. Fluctuations in exchange rates may affect
                       the earning power and asset value of the foreign entity
                       issuing the security and can either increase or decrease
                       the investment's value. Dividend and interest payments
                       may be repatriated based upon the exchange rate at the
                       time of disbursement or payments, and such restrictions
                       on capital flows may be imposed. The characteristics of
                       the securities in the Portfolios, such as the maturity
                       and the type of issuer, will affect yields and yield
                       differentials, which may vary over time.
    
- --------------------------------------------------------------------------------
WHEN-ISSUED AND
DELAYED DELIVERY
TRANSACTIONS
                       From time to time, in the ordinary course of business,
                       any of the Portfolios may purchase newly-issued
                       securities appropriate for the Portfolio on a
                       "when-issued" basis and may purchase or sell securities
                       appropriate for the Portfolio on a "delayed delivery"
                       basis. When-issued or delayed delivery transactions
                       involve a commitment by a Portfolio to purchase or sell
                       particular securities with payment and delivery to take
                       place at a future date. These transactions allow the
                       Portfolio to lock in an attractive purchase price or
                       yield on a security the Portfolio intends to purchase or
                       an attractive sale price on a security the Portfolio
                       intends to sell. Normally, settlement occurs within one
                       month of the purchase or sale. During the period between
                       purchase or sale and settlement, no payment is made or
                       received by a Portfolio and, for delayed delivery
                       purchases, no interest accrues to the Portfolio. A
                       Portfolio will only make commitments to purchase
                       securities on a when-issued or delayed delivery basis
                       with the intention of actually acquiring the securities,
                       but each Portfolio reserves the right to sell such
                       securities before the settlement date if deemed
                       advisable.
                       At the time a Portfolio makes the commitment to purchase
                       a security on a when-issued or delayed delivery basis, it
                       will record the transaction and reflect the amount due
                       and the market value of the security, in determining its
                       net asset value. Likewise, at the time a Portfolio makes
                       the commitment to sell a security on a delayed delivery
                       basis, it will record the transaction and include the
                       proceeds to be received in determining its net asset
                       value; accordingly, any fluctuations in the value of the
                       security sold pursuant to a delayed delivery commitment
                       are ignored in calculating net asset value so long as the
                       commitment remains in effect.
 
                                       19
<PAGE>
                       The market value of the when-issued or delayed delivery
                       securities at any time may be more or less than the
                       purchase price to be paid or the sale price to be
                       received at the settlement date. To the extent that a
                       Portfolio engages in when-issued or delayed delivery
                       transactions, it will do so for the purpose of acquiring
                       or selling Portfolio securities consistent with the
                       Portfolio's investment objectives and policies and not
                       for the purpose of investment leverage or to speculate on
                       interest rate changes. The investment adviser does not
                       believe that a Portfolio's net asset value or income will
                       be adversely affected by the purchase of securities on a
                       when-issued or delayed delivery basis or the sale of
                       securities on a delayed delivery basis.
 
                       Each Portfolio will establish a segregated account with
                       the Fund's custodian bank in which it will maintain cash
                       or U.S. Government securities or other high-grade debt
                       obligations at least equal in value to commitments to
                       purchase securities on a when-issued or delayed delivery
                       basis; subject to this requirement, a Portfolio may
                       purchase securities on a when-issued or delayed delivery
                       basis without limit. To the extent that assets of a
                       Portfolio are held in cash pending the settlement of a
                       purchase of securities, that Portfolio would earn no
                       income; however, it is the investment adviser's intention
                       that each Portfolio will be fully invested to the extent
                       practicable and subject to the policies stated above. In
                       the case of a commitment to sell portfolio securities on
                       a delayed delivery basis, each Portfolio will instruct
                       the custodian to hold the portfolio securities themselves
                       in a segregated account while the commitment is
                       outstanding.

LOANS OF PORTFOLIO
SECURITIES
                       Each Portfolio may, from time to time, lend securities
                       (but not in excess of 20% of its assets) from its
                       portfolio to brokers, dealers and financial institutions,
                       provided that: (i) the loan is secured continuously by
                       collateral consisting of U.S. Government securities,
                       government agency securities, cash or cash equivalents
                       adjusted daily to have a market value at least equal to
                       the current market value of the securities loaned plus
                       accrued interest; (ii) the Portfolio may at any time call
                       the loan and regain the securities loaned; and (iii) the
                       investment adviser (under the review of the Board of
                       Trustees) has reviewed the creditworthiness of the
                       borrower and has found such creditworthiness
                       satisfactory. Any cash collateral will be invested in
                       short-term securities, the income from which will
                       increase the return to the Portfolio.
- --------------------------------------------------------------------------------
COVERED CALL OPTIONS
                       Each Portfolio (other than the Money Market Portfolio)
                       may write (sell) covered call options on portfolio
                       securities representing up to 100% of its net assets in
                       an attempt to enhance investment performance or to reduce
                       the risks associated with investments. A call option
                       gives the purchaser the right to buy, and the writer the
                       obligation to sell, an underlying security at a
                       particular exercise price during the option period. A
                       Portfolio will write call options only on a covered
                       basis, which means that the Portfolio will own the
                       underlying security subject to the call option at all
                       times during the option period. Options written by a
                       Portfolio will normally have expiration dates between
                       three and nine months from the date written. Such options
                       and the securities underlying the option will both be
                       listed on national securities exchanges, except for
                       certain transactions in debt securities and related
                       options need not be so listed.
                       The advantage to a Portfolio of writing covered call
                       options is that the Portfolio receives a premium which
                       constitutes additional income, which would serve both to
                       enhance investment performance and to offset in whole or
                       in part any decline in value of the underlying security.
                       However, the disadvantage is that during the option
                       period the Portfolio would give up the potential for
                       capital appreciation above the exercise price if the
                       underlying security were to rise in value; and that,
                       unless a closing purchase transaction is effected, the
                       Portfolio will be required to continue to hold the
                       underlying security for the entire option period, and
                       would bear the risk of loss if the price of the security
                       were to decline.
- --------------------------------------------------------------------------------
REPURCHASE AGREEMENTS
                       Each Portfolio may enter into repurchase agreements as a
                       means of earning income for periods as short as
                       overnight. A repurchase agreement is an agreement under
                       which the Portfolio purchases a security and the seller
                       agrees, at the time of sale, to repurchase the security
                       at a specified time and price, thereby determining the
                       yield
                                       20
<PAGE>
                       during the Portfolio's holding period. That yield is
                       determined by current short-term rates and may be more or
                       less than the interest rate on the underlying security.
                       The value of the underlying securities is marked to
                       market daily. Should the value of the underlying
                       securities decline, the seller would be required to
                       provide the Portfolio with additional securities so that
                       the aggregate value of the underlying securities was at
                       least equal to the repurchase price. The Portfolios may
                       also enter into a special type of repurchase agreement
                       known as an "open repurchase agreement." An open
                       repurchase agreement varies from the typical repurchase
                       agreement in the following respects: (i) the agreement
                       has no set maturity, but instead matures upon 24 hours'
                       notice to the seller; and (ii) the repurchase price is
                       not determined at the time the agreement is entered into,
                       but instead is based on a variable interest rate and the
                       duration of the agreement.
 
                       The Portfolios may enter into repurchase agreements only
                       with banks or securities dealers and the underlying
                       securities will consist of securities issued or
                       guaranteed by the U.S. Government or its agencies or
                       instrumentalities. If a seller of a repurchase agreement
                       were to default, the Portfolio might experience losses,
                       including delays and expenses in enforcing its rights. To
                       minimize this risk, the investment adviser (under the
                       review of the Board of Trustees) will review the
                       creditworthiness of the seller of the repurchase
                       agreement and must find such creditworthiness
                       satisfactory before a Portfolio may enter into the
                       repurchase agreement.
 
                       A Portfolio may invest no more than 10% of its assets in
                       repurchase agreements maturing in more than seven days,
                       and no more than 25% of its assets in repurchase
                       agreements in which the underlying securities have
                       maturities in excess of one year, although there is no
                       limit on the percentage of each Portfolio's assets which
                       may be invested in repurchase agreements which mature in
                       less than seven days and which have underlying securities
                       with maturities of less than one year. Open repurchase
                       agreements are considered to mature in one day.
- --------------------------------------------------------------------------------
   
INVESTMENTS IN
CAPITAL
                       Each Portfolio (other than the Blue Chip and Money Market
                       Portfolios) may invest in
SECURITIES
    
   
                       capital (trust-preferred) securities. These securities
                       are issued by trusts or other special purpose entities
                       created for the purpose of investing in junior
                       subordinated debentures. Capital securities, which have
                       no voting rights, have a final stated maturity date and a
                       fixed schedule for periodic payments. In addition,
                       capital securities have provisions which provide
                       preference over common and preferred stock upon
                       liquidation, although the securities are subordinated to
                       other, more senior debt. The issuers of these securities
                       may defer interest payments for a number of years (up to
                       five years), although interest continues to accrue
                       cumulatively. In addition, the trust may be terminated
                       and the debentures distributed in liquidation. Because of
                       the structure of these securities, they have the
                       characteristics, and involve the associated risks, of
                       both fixed income and preferred equity securities. At the
                       present time, the Internal Revenue Service treats capital
                       securities as debt. Proposed tax legislation may cause
                       this tax treatment to be modified in the future. In the
                       event that the tax treatment of interest payments of
                       these types of securities is modified, the Portfolio will
                       reconsider the appropriateness of continued investment in
                       these securities. For purposes of percentage limitations
                       applicable to the Portfolio, these securities will be
                       treated as debt securities.

                   PURCHASE OF SHARES
- --------------------------------------------------------------------------------
                       The Fund continuously offers shares of the various
                       Portfolios at the respective net asset values of the
                       Portfolios determined in the manner set forth below under
                       "Net Asset Value Information." The Fund offers its
                       shares, without sales charge, only to the separate
                       accounts of Participating Insurance Companies as the
                       investment medium for the VA contracts or VLI policies
                       issued by the Participating Insurance Companies.

                   REDEMPTION OF SHARES
- --------------------------------------------------------------------------------
 
                       The Fund ordinarily will redeem full and fractional
                       shares of a Portfolio for cash at the net asset value
                       next determined after receipt of a proper notice of
                       redemption. No redemption fee is charged. Except as
                       described below, the Fund is required to pay redemption
                       proceeds within seven days after receipt of a proper
                       notice of redemption; however, the Fund intends to pay
                       redemption proceeds within one business day after receipt
                       of such notice. The Fund may suspend the right of
                       redemption or postpone the date of payment, with respect
                       to the shares of a Portfolio, during any period when (a)
                       trading on the New York Stock Exchange is restricted as
                       determined by the Securities and Exchange Commission or
                       such exchange is closed for trading other than customary
                       weekend and holiday closings; (b) an emergency exists, as
                       determined by the Securities and Exchange Commission, a
                       result of which would make disposal of such Portfolio's
                       securities or determination of the net asset value of
                       such Portfolio not reasonably practicable; or (c) the
                       Securities and Exchange Commission by order permits
                       postponement for the protection of Shareholders.
 
                       If a conflict between VA contract holders and VLI
                       policyowners arose that required a substantial amount of
                       assets be withdrawn from the Fund, orderly portfolio
                       management could be disrupted to the potential detriment
                       of such contract holders and policyowners.

                   NET ASSET VALUE INFORMATION
- --------------------------------------------------------------------------------
 
   
                       The net asset value per share of each Portfolio is
                       determined as of the earlier of 3:00 p.m. (Central Time)
                       or the close of the New York Stock Exchange, on each day
                       that (i) the New York Stock Exchange is open for business
                       (except the day after Thanksgiving, the Friday after
                       Christmas and any day on which the Fund offices are
                       closed because of a weather-related or comparable type of
                       emergency); and (ii) an order for purchase or redemption
                       of shares of the Portfolio is received. The net asset
                       value per share of each Portfolio is computed by dividing
                       the total value of the Portfolio's securities and other
                       assets, less liabilities, by the total number of
                       outstanding shares of such Portfolio.
    
 
                       The Fund reserves the right to calculate or estimate the
                       net asset value of a Portfolio more frequently than once
                       daily if deemed desirable. If the Fund offices should be
                       closed because of a weather-related or comparable type of
                       emergency and the Fund is unable to segregate orders and
                       redemption requests received on that day, the Fund will
                       price those orders and redemptions at the net asset value
                       next determined for each Portfolio.

MONEY MARKET
PORTFOLIO
                       The Money Market Portfolio's securities are valued using
                       the amortized cost method of valuation. This involves
                       valuing a security at cost on the date of acquisition and
                       thereafter assuming a constant accretion of a discount or
                       amortization of a premium to maturity. For a further
                       discussion of the manner in which such values are
                       determined, see the Statement of Additional Information
                       under the heading "Net Asset Value."
- --------------------------------------------------------------------------------
OTHER PORTFOLIOS
                       Portfolio securities that are traded on a national
                       exchange are valued at the last sale price as of the
                       close of business on the day the securities are being
                       valued, or, lacking any sales, at the mean between the
                       closing bid and asked prices. Securities, other than
                       money market instruments, 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. Portfolio
                       securities that are traded both in the over-the-counter
                       market and on a national exchange are valued according to
                       the broadest and most representative market; and it is
                       expected that for debt securities this ordinarily will be
                       the over-the-counter market. Values of securities and
                       assets for which market quotations are not readily
                       available are determined in good faith by, or under the
                       direction of, the Board of Trustees.

<PAGE>
                       Money market instruments are valued at market value,
                       except that debt instruments maturing in 60 days or less
                       are valued using the amortized cost method of valuation
                       described above with respect to the Money Market
                       Portfolio.

                   PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
                       From time to time, the Fund may advertise several types
                       of performance information for a Portfolio. All
                       Portfolios, except the Money Market Portfolio, may
                       advertise "average annual total return" and "total
                       return." The High Grade Bond and High Yield Bond
                       Portfolios may also advertise "yield." The Money Market
                       Portfolio may advertise "yield" and "effective yield."
                       Each of these figures is based upon historical results
                       and is not necessarily representative of the future
                       performance of a Portfolio. The rate of return for a
                       Portfolio should be distinguished from the rate of return
                       of a corresponding Subaccount of a separate account of a
                       Participating Insurance Company, whose rate will reflect
                       the deduction of additional charges, including a
                       mortality and expense risk charge, and therefore will be
                       lower. Contract holders and policyowners should consult
                       the prospectus for such VA contract or VLI policy.
 
                       Average annual total return and total return figures
                       measure both the net income generated by, and the effect
                       of any realized and unrealized appreciation or
                       depreciation of, the underlying investments in the
                       Portfolio for the designated period, assuming the
                       reinvestment of all dividends and distributions during
                       the period. Thus, these figures reflect the change in
                       value of an investment in the Portfolio during a
                       specified period. Average annual total return will be
                       quoted for at least one-, five- and ten-year periods (or,
                       if such periods have not yet elapsed, at the end of a
                       shorter period corresponding to the life of the
                       Portfolio). Average annual total return figures represent
                       the average annual percentage change in the value of a
                       specific dollar amount invested in the Portfolio's shares
                       for the designated period. Total return figures are not
                       annualized and represent the aggregate percentage or
                       dollar value change over the period.
 
                       Yield is a measure of the net investment income per share
                       earned over a specific one-month or 30-day period
                       (seven-day period for the Money Market Portfolio)
                       expressed as a percentage of the Portfolio's net asset
                       value per share at the end of the period (except for the
                       Money Market Portfolio where the net asset value per
                       share at the beginning of the period is used). Yield is
                       an annualized figure which means that it is assumed that
                       the Portfolio generates the same level of investment
                       income over a one-year period. The effective yield for
                       the Money Market Portfolio is calculated similarly, but
                       the net investment income earned is assumed to be
                       compounded when annualized. The Money Market Portfolio's
                       effective yield will be slightly higher than its yield
                       due to this compounding. Semi-annual compounding is
                       assumed for Portfolios other than the Money Market
                       Portfolio.
 
                       From time to time, the Fund may include in its sales
                       literature and shareholder reports for the High Grade
                       Bond and High Yield Bond Portfolios a quotation of the
                       current "distribution rate" for the Portfolios. The
                       distribution rate is simply a measure of the level of
                       income and short-term capital gain dividends distributed
                       for a specified period. It differs from yield, which is a
                       measure of the income actually earned by the Portfolio's
                       investments and from total return, which is a measure of
                       the income actually earned by, plus the effect of any
                       realized or unrealized appreciation or depreciation of
                       such investments, during the period. Distribution rate,
                       therefore, is not intended to be a complete measure of
                       performance. Distribution rate may sometimes be greater
                       than yield since, for instance, it may include short-term
                       gains (which may be non-recurring) and may not reflect
                       the amortization of bond premiums.
 
                       Additionally, from time to time, in advertisements or
                       reports to shareholders, a Portfolio may compare its
                       performance to that of the Consumer Price Index or
                       various unmanaged indexes such as the Dow Jones
                       Industrial Average, the Standard & Poor's 500, the
                       Shearson/Lehman Government and Corporate Bond Index and
                       the Salomon

                       mutual fund quotation services such as Lipper Analytical
                       Services, Inc., an independent mutual fund reporting
                       service, or similar industry services, for purposes of
                       comparing a Portfolio's rank or performance with that of
                       other mutual funds having similar investment objectives.
                       Performance comparisons should not be considered
                       representative of the future performance of any
                       Portfolio.

                       Investment Advisory and Management Services Agreement.
                       This relationship has existed since the Fund commenced
                       operations in 1987.
    
   
                       The Adviser is an indirect subsidiary of FBL Financial
                       Group, Inc., an Iowa corporation. At December 31, 1996,

                       Group, Inc. is owned by Iowa Farm Bureau Federation. The
                       following individuals are officers and/or directors of
                       the Adviser and are officers and/or trustees of the Fund:

                       Timothy J. Hoffman, Dennis M. Marker, James W. Noyce,
                       Richard D. Warming, Sue A. Cornick, Kristi Rojohn and
                       Elaine A. Followwill. The Adviser also acts as the
                       investment adviser to individuals, institutions and two
                       other investment companies: FBL Money Market Fund, Inc.

                       The Adviser handles the investment and reinvestment of
                       the Fund's assets, and is responsible for the overall
                       management of the Fund's business affairs, subject to the
                       review of the Board of Trustees.
 
   
                       Roger F. Grefe and Robert J. Rummelhart serve as managers
                       for various portfolios of the Fund. Mr. Grefe joined FBL
                       in 1986 and has managed the Value Growth and Managed

                       Chip Portfolio through the use of a team approach. As
                       cash accumulates for investment, trading personnel are
                       notified to execute the necessary transactions in order
                       to maintain the relative weights of the equity securities
                       in this Portfolio.

                       As compensation for the advisory and management services
                       provided by the Adviser, the Fund has agreed to pay the
                       Adviser an annual management fee, accrued daily and

                       The Adviser, at its expense, furnishes the Fund with
                       office space and facilities, simple business equipment,
                       advisory, research and statistical facilities, and
                       clerical services and personnel to administer the
                       business affairs of the Fund. The Fund pays its other
                       expenses which include, but are not limited to, the
                       following: net asset value calculations; portfolio
                       transaction costs; interest on Fund obligations;
                       miscellaneous reports; membership dues; reports and
                       notices to Shareholders; all expenses of registration of
                       its shares under federal and state securities laws;
                       investor services (including allocable telephone and
                       personnel expenses); all taxes and fees payable to
                       federal, state or other governmental authorities; fees of
                       Trustees who are not affiliated with the Adviser; and the
                       fees and expenses of independent public auditors, legal
                       counsel, custodian, transfer and dividend disbursing
                       agent and any registrar.
    
 
   
                       The Adviser has agreed to reimburse any Portfolio to the
                       extent that the annual operating expenses (including the
                       investment advisory fee but excluding brokerage,
                       interest, taxes and extraordinary expenses) of that
                       Portfolio exceed 1.50% of the average daily net assets of
                       that Portfolio for any fiscal year of the Portfolio.
                       However, the amount reimbursed shall not exceed the
                       amount of the advisory fee paid by the Portfolio for such
                       period. This reimbursement agreement will remain in
                       effect as long as the Investment Advisory Agreement
                       remains in effect and cannot be changed without
                       shareholder approval. Additionally, the Adviser has
                       agreed to reimburse any Portfolio to the extent that
                       annual operating expenses, including the investment
                       advisory fee, exceed .55% for the period January 1, 1997
                       through April 30, 1997, and .65% for the period May 1,
                       1997 through December 31, 1997. There can be no assurance
                       that the Adviser will continue to limit expenses beyond
                       December 31, 1997.

                   PORTFOLIO TRANSACTIONS
- --------------------------------------------------------------------------------
 
                       With respect to transactions in portfolio securities,
                       whether through a broker as agent or with a dealer as
                       principal, the Adviser endeavors to obtain for the Fund
                       the most favorable prices and efficient execution of
                       orders. Subject to this primary consideration, and while
                       there is no understanding or arrangement to do so, the
                       Adviser places substantially all the Fund's portfolio
                       transactions with brokerage firms which furnish research,
                       statistical and other services to the Fund. Certain
                       affiliates and other clients of the Adviser also place
                       portfolio transactions with these brokerage firms, and
                       such affiliates and clients share the benefits of the
                       research and other services obtained from these brokers.
                       The Adviser regards information which is customarily
                       available only in return for brokerage as among the many
                       elements to be considered in arriving at investment
                       decisions. No specific value can be determined for most
                       such information and services and they are deemed
                       supplemental to the Adviser's own efforts in the
                       performance of its duties under the Investment Advisory
                       and Management Services Agreement. Any research benefits
                       derived are available for all clients.

<PAGE>
                       The investment decisions for the Fund are reached
                       independently from those for the other funds and accounts
                       managed by the Adviser. At certain times one or more
                       Portfolios of the Fund may purchase the same securities
                       at the same time as the other funds and accounts managed
                       by the Adviser. When multiple accounts and/or funds have
                       assets available for investment in the same securities,
                       available investments are allocated as to amount in a
                       manner considered equitable to each. In some cases, this
                       procedure may affect the size or price of the position
                       obtainable for the Fund. It is the opinion of the Board
                       of Trustees that the benefits to the Fund arising out of
                       simultaneous transactions outweigh any disadvantages.

                   TAXES AND DISTRIBUTIONS
- --------------------------------------------------------------------------------
 
                       For federal income tax purposes, each Portfolio will be
                       treated as a separate entity. Each Portfolio intends to
                       qualify each year as a "regulated investment company"
                       under the Internal Revenue Code as amended ("Code"). By
                       so qualifying, a Portfolio will not be subject to federal
                       income taxes to the extent that its net investment income
                       and net realized capital gains are distributed to the
                       separate accounts of insurance companies.
 
                       Since the Shareholders of the Fund are the separate
                       accounts of Participating Insurance Companies, no
                       discussion is included herein as to the federal income
                       tax consequences at the shareholder level. For
                       information concerning the federal tax consequences to
                       the purchasers of the VA contracts and VLI policies, see
                       the attached prospectus for such contract or policy.
 
                       Federal tax law imposes a four-percent nondeductible
                       excise tax on each regulated investment company with
                       respect to an amount, if any, by which such company does
                       not meet distribution requirements specified in such tax
                       laws. Each Portfolio intends to comply with such
                       distribution requirements and thus does not expect to
                       incur the four-percent nondeductible excise tax.

DISTRIBUTIONS
   
                       VALUE GROWTH, BLUE CHIP AND MANAGED PORTFOLIO
                       DISTRIBUTIONS: Each Portfolio normally follows the
                       practice of distributing substantially all net investment
                       income and substantially all net short-term and long-term
                       capital gains, if any, during the Fund's fiscal year.
    
                       HIGH GRADE BOND AND HIGH YIELD BOND PORTFOLIO
                       DISTRIBUTIONS: On each day that a Portfolio's net asset
                       value per share is calculated, 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. Any net
                       short-term and long-term gains will be declared and
                       distributed periodically, but in no event less frequently
                       than annually.
 
                       MONEY MARKET PORTFOLIO DISTRIBUTIONS: On each day that
                       the net asset value per share of the Money Market
                       Portfolio is determined, the Money Market 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.
 
                       It is the Fund's intention to distribute substantially
                       all its net investment income, if any, and any net
                       realized capital gains of each Portfolio. All
                       distributions are reinvested in additional shares of the
                       respective Portfolio at net asset value unless a
                       Shareholder elects to have such distributions paid in
                       cash.

                   ORGANIZATION OF THE FUND
- --------------------------------------------------------------------------------
 
                       The Fund was organized as a business trust under the laws
                       of the Commonwealth of Massachusetts on November 3, 1986.
 
                       The Declaration of Trust permits the Trustees to issue an
                       unlimited number of full and fractional shares of the
                       Portfolios and to divide or combine the shares of any
                       Portfolio into a greater or lesser number of shares of
                       that Portfolio without thereby changing the proportionate
                       beneficial interests in the Portfolio. The shares of the
                       Fund are
 
                                       26
<PAGE>
                       divided into six separate series (i.e., Portfolios), and
                       the shares of each Portfolio have equal rights and
                       privileges and represent an equal proportionate interest
                       with all other shares of that Portfolio. Upon liquidation
                       of the Fund or any Portfolio of the Fund, Shareholders of
                       each Portfolio are entitled to share pro rata in the net
                       assets of that Portfolio available for distribution to
                       Shareholders. Shares have no preemptive or conversion
                       rights. The right of redemption is described elsewhere
                       herein. Shares of each Portfolio are fully paid and
                       non-assessable by the Fund. The Trustees are authorized
                       to classify unissued shares of the Fund by assigning them
                       to a Portfolio for issuance.
 
                       The assets received by the Fund on the sale of shares of
                       each Portfolio and all income, earnings, profits and
                       proceeds thereof, (subject only to the rights of
                       creditors), are allocated to each Portfolio, and
                       constitute the assets of such Portfolio. The assets of
                       each Portfolio are required to be segregated on the
                       Fund's books of account.
 
                       Under Massachusetts law, shareholders of a business trust
                       may, under certain circumstances, be held personally
                       liable as partners for the obligations of the Fund. The
                       Declaration of Trust contains an express disclaimer of
                       Shareholder liability for acts or obligations of the Fund
                       and requires that notice of such disclaimer be given in
                       each instrument entered into or executed by the Fund. The
                       Declaration of Trust also provides for indemnification
                       out of Fund property of any Shareholder held personally
                       liable for the claims and liabilities to which a
                       Shareholder may become subject by reason of being or
                       having been a Shareholder. Thus, the risk of a
                       Shareholder incurring financial loss on account of
                       Shareholder liability is limited to circumstances in
                       which the Fund itself would be unable to meet its
                       obligations.
 
   
                       As of the date of this prospectus, Farm Bureau Life
                       Insurance Company owned more than 25% of the Money Market
                       Portfolio and will be deemed to control the Portfolio.
                       Farm Bureau Life Insurance Company is a subsidiary of FBL
                       Financial Group, Inc. Such shares have been acquired for
                       investment and can only be disposed of by redemption or
                       transfer to an affiliate. The organizational expenses of
                       the Fund have been paid by Farm Bureau Life Insurance
                       Company.

SHAREHOLDER VOTING
RIGHTS
                       Shareholders have the right to vote on the election of
                       Trustees and on any and all matters which, by law or the
                       provisions of the Fund's by-laws, they may be entitled to
                       vote. Shareholders of all Portfolios vote for a single
                       set of Trustees; thereafter, the Trustees will serve for
                       terms of unlimited duration (subject to certain removal
                       procedures by the Trustees or the Shareholders). The Fund
                       does not intend to hold annual meetings of Shareholders.
                       The Board of Trustees has the power to alter the number
                       of Trustees and to appoint successor Trustees, provided
                       that immediately after the appointment of any successor
                       Trustee at least two-thirds of the Trustees have been
                       elected by the Shareholders of the Fund. However, if at
                       any time less than a majority of the Trustees holding
                       office has been elected by the Shareholders, the Trustees
                       are required to call a special meeting of Shareholders
                       for the purpose of electing Trustees to fill any existing
                       vacancies in the Board.
                       To the extent required by law, the Participating
                       Insurance Companies will vote Fund shares held in their
                       separate accounts in accordance with instructions
                       received from the VLI policyowners or VA contract holders
                       having voting interests in the separate accounts. In
                       addition, to the extent required by law, Farm Bureau Life
                       Insurance

<PAGE>
                       Company will vote Fund shares held in its general account
                       in proportion to voting instructions received from its
                       VLI policyowners and its VA contract holders. Each share
                       will have one vote and fractional shares will be counted.
                       On any matters affecting an individual Portfolio, only
                       the Shareholders of that Portfolio will be entitled to
                       vote. On matters relating to all the Portfolios, but
                       affecting the Portfolios differently, separate votes by
                       Portfolio will be required. Shares for which no voting
                       instructions are received shall be voted by the
                       Participating Insurance Companies in proportion to the
                       shares for which voting instructions are received.
 
                       As used in this Prospectus and in the Statement of
                       Additional Information, the phrase "majority vote" of a
                       Portfolio (or of the Fund) means the vote of the lesser
                       of (i) 67% of the shares of the Portfolio (Fund) present
                       at a meeting if the holders of more than 50% of the
                       outstanding shares are present in person or by proxy, or
                       (ii) more than 50% of the outstanding shares of the
                       Portfolio (Fund).

                   APPENDIX A -- MONEY MARKET INSTRUMENTS
- --------------------------------------------------------------------------------
 
                       The Money Market Portfolio invests in money market
                       instruments maturing in thirteen months or less from the
                       time of investment, including the instruments described
                       below. In addition, the other Portfolios subject to their
                       respective investment objectives, may invest in certain
                       money market instruments.
 
                            U.S. GOVERNMENT SECURITIES: Bills, notes, bonds and
                            other debt securities issued by the U.S. Treasury.
                           These are direct obligations of the U.S. Government
                           and differ mainly in the length of their maturities.
 
                            U.S. GOVERNMENT AGENCY OR INSTRUMENTALITY
                            SECURITIES: Debt securities issued or guaranteed by
                           agencies or instrumentalities of the U.S. Government.
                           Although these securities are not direct obligations
                           of the U.S. Government, some are supported by the
                           full faith and credit of the U.S. Treasury; others
                           are supported only by the limited right of the issuer
                           to borrow from the U.S. Treasury; and others are
                           supported only by the credit of the instrumentality
                           and not the U.S. Treasury.
 
                            OBLIGATIONS OF BANKS OR SAVINGS
                            INSTITUTIONS: Certificates of deposit, bankers'
                           acceptances and other short-term debt obligations of
                           commercial banks or savings and loan associations.
                           None of the Portfolios will invest in any instruments
                           issued by a commercial bank unless it has total
                           assets of at least $100 million and has its deposits
                           insured by the Federal Deposit Insurance Corporation
                           ("FDIC"). Similarly, the Portfolios will not invest
                           in any instrument issued by a savings and loan
                           association unless it has total assets of at least
                           $100 million, has been issued a charter by the Office
                           of Thrift Supervision ("OTS") or was formerly a
                           member of the Federal Home Loan Bank System and is
                           now subject to regulation by the OTS and is insured
                           by the FDIC. However, the Portfolios may invest in an
                           obligation of a bank or savings and loan association
                           with assets of less than $100 million if the
                           principal amount of such obligation is fully covered
                           by FDIC insurance. The limit of such coverage is
                           currently $100,000.
 
                            COMMERCIAL PAPER: Short-term unsecured promissory
                            notes issued by corporations, primarily to finance
                           short-term credit needs.
 
                           In addition, the Fund will invest in commercial paper
                           issued by major corporations in reliance on the
                           so-called "private placement" exemption from
                           registration by Section 4(2) of the Securities Act of
                           1933 ("Section 4(2) paper") subject to the below
                           noted requirements with respect to ratings. Section
                           4(2) paper is restricted as to disposition under the
                           federal securities laws, and generally is sold to
                           institutional investors such as the Fund, who agree
                           that it is purchasing the paper for investment and
                           not with a view to public distribution. Any resale by
                           the purchaser must be in an exempt transaction.
                           Section 4(2) paper normally is resold to other
                           institutional investors through or with the
                           assistance of the issuer or investment dealers who
                           make a market in the Section 4(2) paper, thus
                           providing liquidity. The Fund's investment adviser
                           considers the legally restricted but readily saleable
                           Section 4(2) paper to be liquid; however, the paper
                           will be treated as illiquid unless, pursuant to
                           procedures approved by the Board of Trustees, a
                           particular investment in Section 4(2) paper is
                           determined to be liquid. The investment adviser
                           monitors the liquidity of the Fund's investments in
                           Section 4(2) paper on a continuing basis.
 
                            OTHER CORPORATE DEBT SECURITIES: Outstanding
                            nonconvertible corporate debt securities (e.g.,
                           bonds and debentures) which were not issued as
                           short-term obligations but which have thirteen months
                           or less remaining until maturity.

                           As to obligations of banks or savings institutions,
                           commercial paper, other corporate debt securities and
                           repurchase agreements, the Portfolio will only invest
                           in U.S. dollar-denominated instruments which the
                           Board of Trustees determines present minimal credit
                           risks and which, at the time of acquisition,
                           generally are either:
 
                            1. rated in one of the two highest rating categories
                               by at least two nationally recognized statistical
                               rating organizations ("NRSRO"); or
 
                            2. rated in one of the two highest rating categories
                               by only one NRSRO if that NRSRO is the only NRSRO
                               that has rated the instrument or issuer; or
 
                            3. in the case of an unrated instrument, determined
                               by the Board of Trustees to be of comparable
                               quality to either of the above; or
 
                            4. issued by an issuer that has received a rating of
                               the type described in 1 or 2 above on other
                               securities that are comparable in priority and
                               security to the instrument.
 
                            FLOATING AND VARIABLE RATE SECURITIES: The Portfolio
                            may invest in instruments having rates of interest
                           that are adjusted periodically or that float
                           continuously or periodically according to formulas
                           intended to minimize fluctuation in the value of the
                           instruments ("Variable Rate Securities"). The
                           interest rate on a Variable Rate Security is
                           ordinarily determined by reference to, or is a
                           percentage of, a specified market rate such as a
                           bank's prime rate, the 90-day U.S. Treasury Bill
                           rate, or the rate of return on commercial paper or
                           bank certificates of deposit. Generally, the changes
                           in the interest rate on Variable Rate Securities
                           reduce the fluctuation in the market value of such
                           securities. Accordingly, as interest rates decrease
                           or increase, the potential for capital appreciation
                           or depreciation is less than for fixed-rate
                           obligations. Some Variable Rate Securities have a
                           demand feature ("Variable Rate Demand Securities")
                           entitling the purchaser to resell the securities at
                           an amount approximately equal to the principal amount
                           thereof plus accrued interest. As in the case for
                           other Variable Rate Securities, the interest rate on
                           Variable Rate Demand Securities varies according to
                           some specified market rate intended to minimize
                           fluctuation in the value of the instruments. Some of
                           these Variable Rate Demand Securities are unrated,
                           their transfer is restricted by the issuer and there
                           is little if any secondary market for the securities.
                           Thus, any inability of the issuers of such securities
                           to pay on demand could adversely affect the liquidity
                           of these securities. The Portfolio determines the
                           maturity of Variable Rate Securities in accordance
                           with Securities and Exchange Commission rules which
                           allow the Portfolio to consider certain of such
                           instruments as having maturities shorter than the
                           maturity date on the face of the instrument.

                   APPENDIX B -- QUALITY COMPOSITION OF BOND PORTFOLIOS
- --------------------------------------------------------------------------------
   
                       The tables below reflect the average composition by
                       quality rating of the investment securities of the High
                       Yield Bond Portfolio and the High Grade Bond Portfolio
                       for the fiscal year ended December 31, 1996. Percentages
                       are weighted averages based upon the portfolio
                       composition at the end of each month during the year. The
                       percentage of total assets represented by bonds rated by
                       Moody's and Standard & Poor's ("S&P") is shown. The
                       percentage of total assets represented by unrated bonds
                       is also shown. Although not specifically rated by Moody's
                       or Standard & Poor's, U.S. Government securities are
                       reflected as Aaa and AAA (highest quality) for purposes
                       of the tables. The category noted as "Cash and Other
                       Assets" includes all assets other than the rated and
                       unrated bonds reflected in the table including, without
                       limitation, equity securities, preferred stocks, money
                       market instruments, repurchase agreements, options and
                       cash.
    
 
                       The allocations reflected in the tables do not
                       necessarily reflect the view of the investment adviser as
                       to the quality of the bonds in the Portfolio on the date
                       shown; and they are not necessarily representative of the
                       composition of the Portfolio at other times. The
                       composition of the Portfolio will change over time.

                       "Appendix C--Description of Corporate Bond Ratings." The
                       ratings of Moody's and Standard & Poor's represent their
                       opinions as to the capacity to pay interest and principal
                       of the securities that they undertake to rate. It should
                       be emphasized, however, that ratings are relative and
                       subjective and do not evaluate market value risk. After
                       purchase by a Portfolio, an obligation may cease to be
                       rated or its rating may be reduced. Neither event would
                       require a Portfolio to eliminate the obligation from its
                       portfolio. An issue may be unrated simply because the
                       issuer chose not to have it rated, and not necessarily
                       because it is of lower quality. Unrated issues may be
                       less marketable.

<TABLE>
<S>   <C>         <C>
              Aaa: Bonds that are rated Aaa are judged to be of the best
                  quality. They carry the smallest degree of investment risk
                  and are generally referred to as "gilt edge." Interest
                  payments are protected by a large or exceptionally stable
                  margin and principal is secure. While the various protective
                  elements are likely to change, such changes as can be
                  anticipated are most unlikely to impair the fundamentally
                  strong position of such issues.
 
               Aa: Bonds that are rated Aa are judged to be of high quality by
                  all standards. Together with the "Aaa" group they comprise
                  what are generally known as high-grade bonds. They are rated
                  lower than the best bonds because margins of protection may
                  not be as large as in "Aaa" securities or fluctuation of
                  protective elements may be of greater amplitude or there may
                  be other elements present which make the long-term risks
                  appear somewhat larger than with "Aaa" securities.
 
                A: Bonds that are rated A possess many favorable investment
                  attributes and may be considered as upper medium-grade
                  obligations. This rating indicates an extremely strong
                  capacity to pay principal and interest which is considered
                  adequate but elements may be present which suggest a
                  susceptibility to impairment sometime in the future.
 
              Baa: Bonds rated Baa are considered medium-grade obligations,
                  i.e., they are neither highly protected nor poorly secured.
                  Interest payments and principal security appear adequate for
                  the present but certain protective elements may be lacking
                  or may be characteristically unreliable over any great
                  length of time. Such bonds lack outstanding investment
                  characteristics and in fact have speculative characteristics
                  as well.
 
               Ba: Bonds rated Ba are judged to have speculative elements;
                  their future cannot be considered as well-assured. Often the
                  protection of interest and principal payments may be very
                  moderate and thereby not well-safeguarded during both good
                  and bad times over the future. Uncertainty of position
                  characterizes bonds in this class.
 
                B: Bonds rated B generally lack characteristics of a desirable
                  investment. Assurance of interest and principal payments or
                  of maintenance of other terms of the contract over any long
                  period of time may be small.
 
              Caa: Bonds rated Caa are of poor standing. Such issues may be in
                  default or there may be present elements of danger with
                  respect to principal or interest.
 
               Ca: Bonds rated Ca represent obligations which are speculative
                  in a high degree. Such issues are often in default or have
                  other market shortcomings.

              AAA: Bonds rated AAA are highest grade debt obligations. This
                  rating indicates an extremely strong capacity to pay
                  principal and interest.
 
               AA: Bonds rated AA also qualify as high-quality obligations.
                  Capacity to pay principal and interest is very strong, and
                  in the majority of instances they differ from "AAA" issues
                  only in a small degree.
 
                A: Bonds rated A have a strong capacity to pay principal and
                  interest, although they are more susceptible to the adverse
                  effects of changes in circumstances and economic conditions.

<TABLE>
<S>   <C>         <C>
              BBB: Bonds rated BBB are regarded as having an adequate capacity
                  to pay principal and interest. Whereas they normally exhibit
                  protection parameters, adverse economic conditions or
                  changing circumstances are more likely to lead to a weakened
                  capacity to pay principal and interest for bonds in this
                  category, than for bonds in the "A" category.
 
                  Bonds rated BB, B, CCC and CC are regarded, on balance, as
                  predominantly speculative with respect to the issuer's
                  capacity to pay interest and repay principal in accordance
                  with the terms of the obligations. BB indicates the lowest
                  degree of speculation and CC the highest degree of
                  speculation. While such bonds will likely have some quality
                  and protective characteristics, these are outweighed by
                  large uncertainties or major risk exposures to adverse
                  conditions.
      BB-B-CCC-CC:
 
                D: Bonds rated D are in default, and payment of interest and/or
                  principal is in arrears.
 
                  Plus (+) or Minus (-): The ratings from "AA" to "BB" may be
                  modified by the addition of a plus or minus sign to show
                  relative standing within the rating categories.
 
               NR: Not rated by the indicated rating agency.

                    DESCRIPTION OF COMMERCIAL PAPER RATINGS
 
MOODY'S INVESTORS SERVICE, INC.
 
<TABLE>
<S>   <C>         <C>
              P-1: The rating P-1 is the highest commercial paper rating
                  assigned by Moody's and indicates that, in Moody's opinion,
                  the issuer or supporting institution has a superior ability
                  for repayment of senior short-term debt obligations. P-1
                  repayment ability will often be evidenced by many of the
                  following characteristics: (1) leading market positions in
                  well-established industries, (2) high rates of return on
                  funds employed, (3) conservative capitalization structures
                  with moderate reliance on debt and ample asset protection,
                  (4) broad margins in earnings coverage of fixed financial
                  charges and high internal cash generation and (5)
                  well-established access to a range of financial markets and
                  assured sources of alternate liquidity.
 
              P-2: The rating P-2 indicates that, in Moody's opinion, the
                  issuer or supporting institution has a strong ability for
                  repayment of senior short-term debt obligations. Strong
                  ability for repayment will normally be evidenced by many of
                  the characteristics listed under the description of "P-1."
                  Earnings trends and coverage ratios, while sound, may be
                  more subject to variation. Capitalization characteristics,
                  while still appropriate, may be more affected by external
                  conditions. Ample alternate liquidity is maintained.

                 INVESTMENT OBJECTIVES, POLICIES AND TECHNIQUES
 
    The investment objectives and policies of each of the six Portfolios are set
forth in the Prospectus under the heading "Investment Objectives and Policies of
the Portfolios." A description of certain investment strategies and techniques
applicable to some or all of the Portfolios is set forth in the Prospectus under
the heading "Description of Certain Investment Techniques." A description of the
money market instruments in which the Money Market Portfolio may invest is
contained in Appendix A to the Prospectus. A description of the corporate bond
and commercial paper ratings of Moody's Investors Services, Inc. ("Moody's") and
Standard Poor's Corporation ("Standard & Poor's") is contained in Appendix C to
the Prospectus.
 
    The following is intended to augment the explanation in the Prospectus of
certain strategies and techniques which are applicable to one or more of the
Portfolios.
 
LOANS OF PORTFOLIO SECURITIES
 
    Each Portfolio may from time to time lend securities (but not in excess of
20% of its assets) from its portfolio to brokers, dealers and financial
institutions, provided that: (i) the loan is secured continuously by collateral
consisting of U.S. Government securities, government agency securities, or cash
or cash equivalents adjusted daily to have a market value at least equal to the
current market value of the securities loaned plus accrued interest; (ii) the
Portfolio may at any time call the loan and regain the securities loaned; and
(iii) the Adviser (under the review of the Board of Trustees) has reviewed the
creditworthiness of the borrower and found such creditworthiness satisfactory.
The collateral will be invested in short-term securities, the income from which
will increase the return to the Portfolio.
 
    The Portfolio will retain all rights of beneficial ownership in the loaned
securities, including voting rights and rights to interest or other
distributions, and will have the right to regain record ownership of loaned
securities to exercise such beneficial rights. The Portfolio may pay reasonable
finders', administrative and custodial fees to persons unaffiliated with the
Fund in connection with the arranging of such loans. Unless certain requirements
contained in the Internal Revenue Code are satisfied, the dividends, interest
and other distributions received by the Portfolio on loaned securities may not
be treated, for tax purposes, as qualified income for the purposes of the 90%
test discussed under "Taxes." Each Portfolio intends to loan portfolio
securities only to the extent that such activity does not jeopardize such
Portfolio's qualification as a regulated investment company under Subchapter M
of the Internal Revenue Code.
 
COVERED CALL OPTIONS
 
    Each Portfolio (other than the Money Market Portfolio) may write (sell)
covered call options on its portfolio securities in an attempt to enhance
investment performance. A call option is a short-term contract, ordinarily
having a duration of nine months or less which gives the purchaser of the
option, in return for a premium paid, the right to buy, and the writer of the
option the obligation to sell, the underlying security at the exercise price at
any time prior to the expiration of the option period. An option is covered when
the writer owns the optioned security.
 
    A Portfolio may write covered call options on debt securities that are
traded over-the-counter. When a Portfolio writes an over-the-counter option,
there is no assurance that the Portfolio will be able to enter into a closing
purchase transaction. It may not always be possible for the Portfolio to
negotiate a closing purchase transaction with the same dealer for the same
exercise price and expiration date as the option which the Portfolio previously
had written. Although the Portfolio may choose to purchase an option from a
different dealer, the Portfolio would then be subject to the additional credit
risk of such dealer. If the Portfolio is unable to effect a closing purchase
transaction, it will not be able to sell the underlying security until the
option expires or until it delivers the underlying security upon exercise.
 
    A Portfolio will write covered call options both to reduce the risks
associated with certain of its investments and to increase total investment
return. In return for the premium income, the Portfolio will forgo the
opportunity to profit from an increase in the market price of the underlying
security above the
 
                                       3
<PAGE>
exercise price so long as its obligations under the contract continue, except
insofar as the premium represents a profit. Moreover, in writing the option, the
Portfolio will retain the risk of loss should the price of the security decline,
which loss the premium is intended to offset in whole or in part. A Portfolio,
in writing call options, must assume that the call may be exercised at any time
prior to the expiration of its obligations as a writer and, that in such
circumstances, the net proceeds realized from the sale of the underlying
securities pursuant to the call may be substantially below the prevailing market
price. Covered call options and the securities underlying the option will be
listed on national securities exchanges, except that certain transactions in
debt securities and related options need not be so listed.
 
GINNIE MAE CERTIFICATES
 
    The Managed Portfolio, High Grade Bond Portfolio and High Yield Bond
Portfolio may each invest in debt securities ("Ginnie Maes") of the Government
National Mortgage Association ("GNMA"), a government corporation within the U.S.
Department of Housing and Urban Development. Ginnie Mae certificates are
securities representing part ownership in a pool of mortgage loans. These loans,
which are issued by lenders such as mortgage bankers, commercial banks and
savings and loan associations, are either insured by the Federal Housing
Administration or the Farmers Home Administration or guaranteed by the Veterans
Administration. A pool of these mortgages is assembled and, after being approved
by GNMA, is offered to investors through securities dealers.
 
    The Ginnie Maes in which these Portfolios may invest are of the "modified
pass-through" type, which means that GNMA guarantees the timely payment of
principal and interest installments (whether or not the amounts are collected by
the issuer of the Ginnie Maes). The National Housing Act provides that the full
faith and credit of the United States is pledged to the timely payment of
principal and interest by GNMA of amounts due on these Ginnie Maes, and an
assistant attorney general of the United States has rendered an opinion that
this guarantee by GNMA is a general obligation of the United States backed by
its full faith and credit. Under the other general type of Ginnie Maes, referred
to as "straight pass-through" Ginnie Maes, the payment of principal and interest
on a timely basis is not guaranteed.
 
    The average life of Ginnie Maes varies with the maturities of the underlying
mortgage instruments with maximum maturities of 30 years. The average life is
likely to be substantially less than the original maturity of the mortgage pools
underlying the securities as the result of prepayments or refinancing of such
mortgages or foreclosure. Such prepayments are passed through to the registered
holder with the regular monthly payments of principal and interest and have the
effect of reducing future payments. Due to the guarantee of Ginnie Maes by GNMA,
foreclosures impose no risk to the principal invested.
 
    The average life of pass-through pools varies with the maturities of the
underlying mortgage instruments. In addition, a pool's term may be shortened by
unscheduled or early payments of principal and interest on the underlying
mortgages. The occurrence of mortgage prepayments is affected by factors
including the level of interest rates, general economic conditions, the location
and age of the mortgage and other social and demographic conditions. As
prepayment rates vary widely, it is not possible to accurately predict the
average life of a particular pool. However, statistics indicate that the average
life of the type of mortgages backing the majority of Ginnie Maes is
approximately 12 years. For this reason, it is standard practice to treat Ginnie
Maes as 30-year mortgage-backed securities that prepay fully in the twelfth
year. Pools of mortgages with other maturities or different characteristics will
have varying assumptions for average life. The assumed average life of pools of
mortgages having terms of less than 30 years is less than 12 years, but
typically not less than 5 years.
 
    The coupon rate of interest on Ginnie Maes is lower than the interest rate
paid on the VA-guaranteed or FHA-insured mortgages underlying the certificates,
but only by the amount of the fees paid to GNMA and the issuer. Such fees in the
aggregate usually amount to approximately 1/2 of 1%.
 
    Yields on pass-through securities are typically quoted by investment dealers
and vendors based on the maturity of the underlying instruments and the
associated average-life assumption. In periods of falling interest rates, the
rate of prepayment tends to increase, thereby shortening the actual average life
 
                                       4
<PAGE>
of a pool of mortgage-related securities. Conversely, in periods of rising
rates, the rate of prepayment tends to decrease, thereby lengthening the actual
average life of the pool. Prepayments generally occur when interest rates have
fallen. Reinvestment of prepayments at such times will be at lower rates, which
would lower the return to the Portfolios. The actual yield of each Ginnie Mae is
influenced by the prepayment experience of the mortgage pool underlying the
certificates and may differ from the yield based on the assumed average life.
Interest on Ginnie Maes is paid monthly rather than semi-annually as for
traditional bonds.
 
                            INVESTMENT RESTRICTIONS
 
FUNDAMENTAL POLICIES
 
    In seeking to achieve its investment objective(s), each Portfolio has
adopted the following investment restrictions. These are fundamental policies
and may not be changed without a majority vote of the outstanding shares of each
Portfolio affected. As used in this Statement of Additional Information and in
the Prospectus, the phrase "majority vote" of a Portfolio (or the Fund) means
the vote of the lesser of (i) 67% of the shares of the Portfolio (Fund) present
at a meeting if the holders of more than 50% of the outstanding shares are
present in person or by proxy, or (ii) more than 50% of the outstanding shares
of the Portfolio (Fund). A change in policy affecting only one Portfolio may be
effected by a majority vote of the outstanding shares of such Portfolio.
 
    Except as noted below, each Portfolio may not:
 
   
    1.  As to 75% of the value of each Portfolio's total assets (with the
exception of the Money Market Portfolio which is subject to 100% of the value of
its total assets), purchase securities of any issuer (other than U.S. Government
securities or government agency securities) if, as a result, more than 5% of the
value of the Portfolio's assets (taken at the time of investment) would be
invested in securities of that issuer.
    
 
    2.  Purchase more than 10% of any class of securities of any issuer (other
than U.S. Government securities or government agency securities). For the

be deemed a single class of security and all preferred stocks of an issuer shall
be deemed a single class of security.
 
    3.  Purchase any security, if, immediately after such purchase, more than
25% of the Portfolio's total net assets would be invested in issuers in the same
industry. This restriction does not apply to U.S. Government securities,
government agency securities, obligations of banks or savings institutions, or
to instruments secured by these instruments, such as repurchase agreements for
U.S. Government securities (these instruments are described in Appendix A to the
Prospectus).
 
    4.  Purchase securities of other investment companies, except (i) by
purchase in the open market involving only customary brokers' commissions and
only if immediately thereafter not more than 5% of such Portfolio's total net
assets would be invested in such securities, or (ii) as part of a merger,
consolidation or acquisition of assets.
 
    5.  Purchase or sell (although it may purchase securities of issuers which
invest or deal in) interests in oil, gas or other mineral exploration or
development programs, real estate, commodities or commodity contracts.
 
    6.  Purchase any securities on margin (except that the Portfolio may obtain
such short-term credit as may be necessary for the clearance of purchases and
sales of portfolio securities) or make short sales unless, by virtue of its
ownership of other securities, it has the right to obtain securities equivalent
in kind and amount to the securities sold and, if the right is conditional, the
sale is made upon the same condition.
 
                                       5
<PAGE>
    7.  Purchase or retain the securities of any issuer if any of the officers
or trustees of the Fund or any officers or directors of the Fund's investment
adviser own individually more than .50% of the securities of such issuer and
together own more than 5% of the securities of such issuer.
 
    8.  Issue senior securities, except as appropriate to evidence indebtedness
which a Portfolio is permitted to incur pursuant to (9) below.
 
    9.  Borrow money, except from banks for temporary or emergency purposes, and
in no event in excess of 5% of its total net assets, or pledge or mortgage more
than 15% of its gross assets.
 
    10. Underwrite securities issued by others, except to the extent that it may
be deemed to be a statutory underwriter in the sale of restricted securities
that it holds in its portfolios which require registration under the Securities
Act of 1933 before resale.
 
    11. Participate on a joint (or a joint and several) basis in any trading
account in securities (but this does not include the "bunching" of orders for
the sale or purchase of portfolio securities with the other Portfolios or with
other investment company and client accounts managed by the Fund's investment
adviser or its affiliates to reduce brokerage commissions or otherwise to
achieve best overall execution).
 
    12. Alone, or together with any other Portfolios, make investments for the
purpose of exercising control over, or management of, any issuer.
 
    13. Lend money or securities, except as provided in (14) below (the making
of demand deposits with banks, and the purchase of securities such as bonds,
debentures, commercial paper and short-term obligations in accordance with the
Portfolio's investment objectives and policies, shall not be considered the
making of a loan).
 
    14. Lend its portfolio securities in excess of 20% of its net assets or in a
manner inconsistent with the guidelines set forth under "Description of Certain
Investment Techniques" in the Prospectus and "Investment Objectives, Policies
and Techniques" in this Statement of Additional Information.
 
   
    15. Invest in foreign securities, except as follows: the Value Growth and
Managed Portfolios may invest up to 25% of its net assets in foreign equity and
debt securities traded on U.S. exchanges and payable in U.S. dollars, and the
High Grade Bond and High Yield Bond Portfolios may each invest up to 25% of its
net assets in foreign debt securities traded on U.S. exchanges and payable in
U.S. dollars.
    
 
    16. Write, purchase or sell puts, calls or combinations thereof, other than
writing covered call options.
 
NON-FUNDAMENTAL (OPERATING) POLICIES
 
    The following are non-fundamental (operating) policies approved by the Board
of Trustees. Such policies may be changed by the Board of Trustees without
approval of the Shareholders. These non-fundamental policies are applicable to
each of the Portfolios.
 
   
    1.  Each Portfolio will not invest more than 15% of its total net assets in
"illiquid" securities (except 10% for the Money Market and Blue Chip
Portfolios).
    
 
    2.  Each Portfolio intends to meet either the diversification standards set
by Section 817(h)(2) of the Internal Revenue Code or the diversification
requirements prescribed by regulations promulgated under Section 817(h).
 
    3.  Each Portfolio intends to comply in all material respects with insurance
laws and regulations applicable to investments of separate accounts of
Participating Insurance Companies.
 
    If a percentage limitation is adhered to at the time of investment, a later
increase or decrease in percentage beyond the specified limit resulting from a
change in values or net assets will not be considered a violation.

                               INVESTMENT ADVISER
 
   
    The following information supplements the information set forth in the
Prospectus under the heading "Management of the Fund -- Investment Adviser."
Pursuant to an Investment Advisory and Management Services Agreement dated April
6, 1987 ("Agreement"), FBL Investment Advisory Services, Inc. ("Adviser") acts
as the Fund's investment adviser and manager, subject to the review of the Board
of Trustees. The Adviser is a wholly-owned subsidiary of FBL Financial Services,
Inc., which is a wholly-owned subsidiary of FBL Financial Group, Inc., an Iowa
corporation, 64% of whose outstanding voting stock is owned by Iowa Farm Bureau
Federation, an Iowa not-for-profit corporation. The Adviser also acts as the
investment adviser to individuals, institutions and two other mutual funds: FBL
Money Market Fund, Inc. and FBL Series Fund, Inc. Personnel of the Adviser also
manage investments for the portfolios of insurance companies.
    
 
    The Adviser subscribes to leading bond information services and receives
published reports and statistical compilations from the issuers themselves, as
well as analyses from brokers and dealers who may execute portfolio transactions
for the Fund or the Adviser's other clients. The Adviser regards this
information and material, however, as an adjunct to its own research activities.
 
    Under the Agreement, the Adviser regularly provides the Fund with investment
research, advice and supervision, and furnishes an investment program consistent
with the investment objectives and policies of each Portfolio, determining, for
each Portfolio, what securities shall be purchased and sold and what portion of
the Portfolio's assets shall be held uninvested, subject always to: (i) the
provisions of the Declaration of Trust, the Fund's by-laws, the Investment
Company Act of 1940 and applicable requirements of the Internal Revenue Code;
(ii) the Portfolio's investment objectives, policies and restrictions; and (iii)
such policies and instructions as the Board of Trustees may from time to time
establish. The Adviser also advises and assists the officers of the Fund in
taking such steps as are necessary or appropriate to carry out the decisions of
the Board of Trustees (and any committees thereof) regarding the conduct of the
business of the Fund. The Adviser has agreed to arrange for any of its officers
or directors to serve without salary as trustees, officers or agents of the Fund
if duly elected to such positions.
 
                                       11
<PAGE>
    The Adviser, at its expense, furnishes the Fund with office space and
facilities, simple business equipment, advisory, research and statistical
facilities and clerical services and personnel to administer the business
affairs of the Fund. As compensation for the Adviser's investment advisory,
management and clerical services, as well as the facilities it provides and the
expenses it assumes, the Agreement provides for the payment of a monthly fee as
described in the Prospectus.
 
   
    The Adviser is not required to pay expenses of the Fund other than those set
forth above. Each Portfolio will pay all other expenses incurred in its
operation, including a portion of the Fund's general administrative expenses,
allocated on the basis of the Portfolio's net assets. Expenses that will be
borne directly by the Portfolios include, but are not limited to, the following:
net asset value calculations; portfolio transaction costs; interest on Fund
obligations; miscellaneous reports; membership dues; all expenses of
shareholders' and trustees' meetings and of preparing, printing and mailing
proxy statements, reports and notices to shareholders; all expenses of
registering the Fund's shares under federal and state securities laws; the
typesetting costs of printing Fund prospectuses and supplements thereto;
investor services (including allocable telephone and personnel expenses); all
taxes and fees payable to federal, state or other governmental authorities; the
fees and expenses of independent public auditors, legal counsel, custodian,
transfer and dividend disbursing agent and any registrar; fees of trustees who
are not affiliated with the Adviser; insurance premiums for fidelity bond and
other coverage of the Fund's operations; and such non-recurring expenses as may
arise including actions, suits or proceedings affecting the Fund and the legal
obligation the Fund may have to indemnify its officers and trustees with respect
thereto. See "Underwriting and Distribution Expenses" and "Other Information --
Accounting Services" for a description of certain other Fund expenses.
    
 
   
    The Agreement was approved on March 13, 1987, by the Board of Trustees, and
on August 21, 1990, by Farm Bureau Life Insurance Company, pursuant to voting
instructions of policyowners, as sole Shareholder of the Value Growth Portfolio,
High Grade Bond Portfolio, High Yield Bond Portfolio, Managed Portfolio and the
Money Market Portfolio. An amendment to the Agreement to extend the Agreement to
the Blue Chip Portfolio was approved by the Board of Trustees on August 21,
1990, reapproved on August 15, 1991 and approved by Shareholders of that
Portfolio on November 13, 1991 pursuant to instructions from variable life
insurance policyowners indirectly invested in the Portfolio. Unless earlier
terminated as described below, the Agreement will continue in effect until
October 15, 1997. Thereafter, the Agreement will continue in effect, with
respect to a Portfolio, from year to year so long as its continuation is
approved at least annually by (a) the vote of a majority of those Trustees who
are not parties to the Agreement or "interested persons" of either party to the
Agreement cast in person at a meeting called for the purpose of voting on such
approval, and (b) either (i) the vote of a majority of the Trustees or (ii) the
vote of a majority of the outstanding shares of such Portfolio.
    
 
    The Agreement will be deemed to have been approved or disapproved by the
Shareholders of any Portfolio, if a majority of the outstanding shares of such
Portfolio vote for or against approval of the Agreement, notwithstanding (a)
that the Agreement has not been approved or disapproved by a majority of the
outstanding shares of any other Portfolio, and (b) that the Agreement has not
been approved or disapproved by a vote of a majority of the outstanding shares
of the Fund. The Agreement may be terminated without penalty at any time upon 60
days' notice by either party, and will terminate automatically upon assignment.
 
    The Agreement provides that the Adviser is not liable for any error of
judgment or mistake of law or for any loss suffered by the Fund in connection
with matters to which the Agreement relates, except a loss resulting from
willful misfeasance, bad faith or gross negligence on the part of the Adviser in
the performance of its duties, or from reckless disregard by the Adviser of its
obligations and duties under the Agreement.
 
    Officers and employees of the Adviser from time to time may have
transactions with various banks, including the Fund's custodian bank. It is the
Adviser's opinion that the terms and conditions of such transactions will not be
influenced by existing or potential custodial or other Fund relationships.

    For the fiscal years ended December 31, 1996, 1995 and 1994, the advisory
and management fee expense was $104,228, $65,647 and $39,952, respectively, for
the Value Growth Portfolio; $9,973, $8,481 and $7,489, respectively, for the
High Grade Bond Portfolio; $26,585, $23,073 and $21,507, respectively, for the
High Yield Bond Portfolio; $109,830, $65,457 and $43,500, respectively for the
Managed Portfolio; $9,579, $8,050 and $8,173, respectively, for the Money Market
Portfolio; and $20,647, $9,533 and $4,895, respectively, for the Blue Chip
Portfolio.
    
 
   
    The Adviser has also agreed to reimburse any Portfolio of the Fund to the
extent that the annual operating expenses (including the investment advisory fee
but excluding brokerage, interest, taxes and extraordinary expenses) of that
Portfolio exceed 1.50% of the average daily net assets of that Portfolio for any
fiscal year of the Portfolio. However, the amount reimbursed shall not exceed
the amount of the advisory fee paid by the Portfolio for such period. This
reimbursement agreement will remain in effect for as long as the Investment
Advisory Agreement remains in effect and cannot be changed without a shareholder
vote. In addition, the Adviser has agreed to reimburse any Portfolio to the
extent that annual operating expenses, including the investment advisory fee,
exceed .55% for the period January 1, 1997 through April 30, 1997, and .65% for
the period May 1, 1997 through December 31, 1997. There can be no assurance that
the Adviser will continue to limit expenses beyond December 31, 1997. The
agreement to reimburse any Portfolio to the extent any operating expenses exceed
 .55% also applied to fiscal years ended 1996 and 1995.
    
 
                     UNDERWRITING AND DISTRIBUTION EXPENSES
 
    Pursuant to an Underwriting Agreement ("Underwriting Agreement"), the
Adviser also serves, without compensation from the Fund, as the principal
underwriter and sole distributor of the Fund's shares. Under the terms of the
Underwriting Agreement, the Adviser is not obligated to sell any specific number
of shares. The Agreement was approved on August 12, 1987, by the Board of
Trustees, including a vote of a majority of the trustees who are not "interested
persons" of either party to the Underwriting Agreement. Unless terminated
earlier as described below, the Underwriting Agreement will continue in effect
from year to year so long as its continuance is approved annually by (a) the
vote of a majority of the trustees who are not parties to the Underwriting
Agreement or "interested persons" of either party to the Underwriting Agreement
cast in person at a meeting called for the purpose of voting on such approval,
and (b) either (i) the vote of a majority of the Trustees or (ii) the vote of a
majority of the outstanding shares of the Fund. The Underwriting Agreement may
be terminated without penalty at any time upon six months' notice by either
party, and will terminate automatically upon assignment. The Adviser has
authority, pursuant to the Underwriting Agreement, to enter into similar
contracts with other investment companies.
 
    Pursuant to the Underwriting Agreement, the Fund is responsible for the
payment of all fees and expenses of registering its shares under federal and
state securities laws. The Fund will also pay the fees and expenses incurred in
connection with: (i) the preparation, printing and mailing of annual
prospectuses to existing Shareholders; (ii) the preparation, printing and
mailing of any notice, proxy statement, report, supplemental prospectus or other
communications to Shareholders; and (iii) the printing and mailing of
confirmations of purchases of shares. The Fund will also pay for certain other
items, including, but not limited to, the following: any issue or initial
transfer taxes; the wiring of funds for share purchases and redemptions (unless
paid by the Shareholder who initiates the transaction); and the printing and
postage of business reply envelopes. The above-described expenses will be
allocated among the Portfolios on the basis of their respective net assets.
 
    The Adviser is obligated to pay for the printing (but not the typesetting)
and distribution of prospectuses and statements of additional information to
prospective VA contract and VLI policyholders, and the preparation, printing and
distribution of any reports or other literature or advertising in connection
with the offering of the shares. The Adviser will pay all fees and expenses in
connection with its qualification and registration as a broker or dealer under
federal and state laws. The Adviser will also pay for any activity which is
primarily intended to result in the sale of shares of the Fund.
 
                                       13
<PAGE>
    The Adviser intends to enter into agreements with Participating Insurance
Companies pursuant to which the Participating Insurance Companies will assume
the Adviser's obligation to pay for the printing and distribution of
prospectuses of the Fund in connection with the sale by the Participating
Insurance Companies of VA contracts and VLI policies. The Adviser continuously
offers shares of each Portfolio of the Fund to the separate accounts of
Participating Insurance Companies. Such shares will be sold at their respective
net asset values and therefore will involve no sales charge.
 
    The Adviser also acts as principal underwriter and sole distributor of the
shares of FBL Money Market Fund, Inc. and FBL Series Fund, Inc.
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS
 
    With respect to transactions in portfolio securities, whether through a
broker as agent or with a dealer as principal, the Adviser endeavors to obtain
for the Fund the most favorable prices and efficient execution of orders.
Subject to this primary consideration, the Adviser may place a Portfolio's
transactions with firms that furnish research, statistical and other services.
In particular, the Adviser may direct brokerage transactions to a specific
broker in return for certain data and research-oriented software. Certain
affiliates of the Adviser also place portfolio transactions with these brokerage
firms, and such affiliates share the benefits of the research and other services
obtained from these brokers.
 
    Brokerage research services, as provided in Section 28(e) of the Securities
Exchange Act of 1934, include: advice as to the value of securities; the
advisability of investing in, purchasing or selling securities; the availability
of securities or purchasers or sellers of securities; furnishing analyses and
reports concerning issues, industries, securities, economic factors and trends;
portfolio strategy and performance of accounts; and the execution of securities
transactions and performance of functions incidental thereto (such as clearance
and settlement).
 
   
    If, in the judgment of the Adviser, the Fund or any Portfolio will be
benefitted by such supplemental research services, the Adviser is authorized to
pay greater spreads or commissions than another broker or dealer may charge for
the same transaction. Accordingly, while the Adviser generally seeks reasonably
competitive spreads or commissions, the Portfolios will not necessarily be
paying the lowest spread or commission available in every case. Information
received from brokerage research will be in addition to and not in lieu of the
services required to be performed by the Adviser under the Agreement. The
expenses of the Adviser will not necessarily be reduced as a result of the
receipt of such supplemental information. Neither the Adviser nor any of its
affiliates will receive any brokerage business arising out of portfolio
transactions for the Fund. The Fund paid brokerage commissions during the fiscal
years ended December 31, 1996, 1995, and 1994 of $74,514, $45,472 and $41,247,
respectively.
    
 
    The Portfolios may deal in some instances in securities which are not listed
on a national securities exchange but rather are traded in the over-the-counter
market. The Portfolios may also purchase listed securities through the "third
market." Where transactions are executed in the over-the-counter or "third
market," the Adviser will seek to deal with primary market makers but, when
necessary, will utilize the services of brokers. In all such cases, the Adviser
will attempt to negotiate the best price and execution. Money market instruments
are generally traded directly with the issuer. On occasion, other securities may
be purchased directly from the issuer. The cost of a Portfolio's securities
transactions will consist primarily of brokerage commissions or dealer or
underwriter spreads.
 
    Certain investments may be appropriate for certain of the Portfolios and for
other clients advised by the Adviser. Investment decisions for the Portfolios
and other clients are made with a view to achieving their respective investment
objectives and after consideration of factors such as their current holdings,
availability of cash for investment and the size of their investments in
general. Frequently, a particular security may be bought or sold for only one
client, or in different amounts and at different times for more than one but
less than all clients. Likewise, a particular security may be bought for one or
more clients when one or more other clients are selling the security. In
addition, purchases or sales of the same security may be made for two or more
Portfolios or other clients on the same day. In such event, such
 
                                       14
<PAGE>
transactions will be allocated among the Portfolios or other clients in a manner
believed by the Adviser to be equitable to each. In some cases, this procedure
could have an adverse effect on the price or amount of the securities purchased
or sold by a Portfolio. It is the opinion of the Board of Trustees that the
benefits available, because of the Adviser's organization, outweigh any
disadvantages that may arise from exposure to simultaneous transactions.
Purchase and sale orders for a Portfolio may be combined with those of other
clients of the Adviser in the interest of the most favorable net results to the
Portfolio.
 
                           PURCHASES AND REDEMPTIONS
 
    The following discussion supplements the discussion in the Prospectus under
the headings "Purchase of Shares" and "Redemption of Shares."
 
    Shares of the Fund may be purchased only by the separate accounts of
Participating Insurance Companies. (Please refer to the prospectuses for the VA
contracts and the VLI policies for a description of how to purchase a contract
or policy.)
 
    Shares of each Portfolio are sold at their respective net asset value next
determined after an order for purchase and payment in proper form are received.
Payment for shares is made in federal funds transmitted by wire on the next
business day following the order for purchase.
 
    Shares of each Portfolio are redeemed at their respective net asset value
next determined after a request for redemption is received in proper form. The
Fund may suspend the right of redemption or postpone the date of payment, with
respect to the shares of a Portfolio, during any period when (a) trading on the
New York Stock Exchange is restricted as determined by the Securities and
Exchange Commission or such exchange is closed for trading other than customary
weekend and holiday closings; (b) an emergency exists, as determined by the
Securities and Exchange Commission, as a result of which disposal of such
Portfolio's securities, or determination of the net asset value of such
Portfolio, is not reasonably practicable; or (c) the Securities and Exchange
Commission by order permits such suspension for the protection of Shareholders.
In such event, redemption will be effected at the net asset value next
determined after the suspension has been terminated unless the Shareholder has
withdrawn the redemption request in writing and the request has been received
prior to the day of such determination of net asset value.
 
                                NET ASSET VALUE
 
    The following supplements the discussion in the Prospectus under the heading
"Net Asset Value Information."
 
MONEY MARKET PORTFOLIO
 
    The net asset value per share of the Money Market Portfolio is computed by
dividing the total value of the Portfolio's securities and other assets, less
liabilities (including dividends payable), by the number of shares outstanding.
The assets are determined by valuing the portfolio securities at amortized cost,
pursuant to Rule 2a-7 under the Investment Company Act. The amortized cost
method of valuation involves valuing a security at cost at the time of purchase
and thereafter assuming a constant amortization to maturity of any discount or
premium, regardless of the impact of fluctuating interest rates on the market
value of the instrument.
 
    The purpose of the amortized cost method of valuation is to attempt to
maintain a constant net asset value per share of $1.00. While this method
provides certainty in valuation, it may result in periods during which value, as
determined by amortized cost, is higher or lower than the price the Portfolio
would receive if it sold its portfolio securities. Under the direction of the
Board of Trustees, certain procedures have been adopted to monitor and stabilize
the price per share. Calculations are made to compare the value of the portfolio
securities, valued at amortized cost, with market based values. Market values
are obtained by using actual quotations provided by market makers, estimates of
market value (provided the Board of Trustees has reviewed and approved the
method of making such estimates), or values
 
                                       15
<PAGE>
obtained from yield data relating to classes of money market instruments
published by reputable sources at the mean between the bid and asked prices for
those instruments. If a deviation of 1/2 of 1% or more between the Portfolio's
$1.00 per share net asset value and the net asset value calculated by reference
to market based valuations were to occur, or if there were other deviations
which the Board of Trustees believed would result in dilution or other unfair
results material to Shareholders, the Board of Trustees would consider what
action, if any, should be initiated.
 
    The market value of debt securities usually reflects yields generally
available on securities of similar quality. When yields decline, the market
value of a Portfolio holding higher yielding securities can be expected to
increase; when yields increase, the market value of a Portfolio invested at
lower yields can be expected to decline. In addition, if the Portfolio has net
redemptions at a time when interest rates have increased, the Portfolio may be
forced to sell portfolio securities prior to maturity at a price below the
Portfolio's carrying value. Also, because the Portfolio generally will be valued
at amortized cost rather than market value, any yield quoted may be different
from the yield that would result if the entire Portfolio were valued at market
value, since the amortized cost method does not take market fluctuation into
consideration.
 
OTHER PORTFOLIOS
 
    The net asset value per share of each Portfolio other than the Money Market
Portfolio is computed by dividing the total value of the Portfolio's securities
and other assets, less liabilities, by the number of Portfolio shares then
outstanding. Securities traded on a national exchange are valued at the last
sale price as of the close of business on the day the securities are being
valued, or, lacking any sales, at the mean between closing bid and asked prices.
Securities other than money market instruments traded in the over-the-counter
market are valued at the mean between closing bid and asked prices or at yield
equivalent as obtained from one or more dealers that make markets in the
securities. Securities traded both in the over-the-counter market and on a
national exchange are valued according to the broadest and most representative
market, and it is expected that for debt securities this ordinarily will be the
over-the-counter market. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Trustees. Money market instruments are
valued at market value, except that debt instruments maturing in 60 days or less
are valued using the amortized cost method of valuation.
 
    The proceeds received by each Portfolio for each issue or sale of its
shares, and all income, earnings, profits and proceeds thereof, subject only to
the rights of creditors, are allocated specifically to such Portfolio, and
constitute the underlying assets of such Portfolio. The underlying assets of
each Portfolio are segregated on the Fund's books of account, and are charged
with the liabilities of such Portfolio and with a share of the general
liabilities of the Fund. Expenses with respect to any two or more Portfolios are
allocated in proportion to the net assets of the respective Portfolios except
where allocations of direct expenses can otherwise be fairly made.
 
                                     TAXES
 
    For federal income tax purposes, each Portfolio is treated as a separate
entity. Each Portfolio intends to qualify and elects to be taxed as a "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986, as
amended ("Code"). If a Portfolio qualifies as a "regulated investment company"
and complies with the provisions of the Code, such Portfolio will be relieved
from federal income tax and the four percent deductible federal excise tax, on
the part of its net ordinary income and net realized capital gain which it
distributes to Shareholders. To qualify for treatment as a "regulated investment
company," each Portfolio must, among other things, derive in each taxable year
at least 90 percent of its gross income from dividends, interest, payments with
respect to securities loans, and gains from the sale or other disposition of
stock or securities or foreign currencies (subject to the authority of the
Secretary of the Treasury to exclude foreign currency gains that are not
ancillary to the Portfolio's principal business of investing in stock or
securities or options and futures with respect to
 
                                       16
<PAGE>
such stock or securities), or other income (including but not limited to gains
from options, futures, or forward contracts) derived with respect to its
business of investing in such stocks, securities, or currencies. In addition, to
qualify for treatment as a "regulated investment company," each Portfolio must
derive less than 30 percent of its gross income in each taxable year from gains
(without deduction for losses) from the sale or other disposition of securities
held for less than three months. In order to meet the 30 percent requirement, a
Portfolio may be required to defer disposing of certain futures contracts and
underlying securities beyond the time when it might otherwise be advantageous to
do so.
 
    Since the Shareholders of the Fund will be the separate accounts of the
Participating Insurance Companies, no discussion is included herein as to the
federal income tax consequences at the shareholder level. For information
concerning the federal income tax consequences to the holders of VA contracts or
VLI policies, see the prospectuses for such contracts or policies.
 
    The discussion under "Taxes and Distributions" in the Prospectus, in
conjunction with the foregoing, is a general summary of applicable provisions of
the Code and Treasury Regulations now in effect as currently interpreted by the
courts and the Internal Revenue Service. The Code and these Regulations, as well
as the current interpretations thereof, may be changed at any time by
legislative, judicial, or administrative action. The above discussion covers
only Federal tax considerations with respect to the Fund. State and local taxes
vary.
 
                          DIVIDENDS AND DISTRIBUTIONS
 
    The following supplements the discussion of dividends and distributions in
the Prospectus under the heading "Taxes and Distributions."
 
MONEY MARKET PORTFOLIO
 
   
    The Portfolio declares dividends of all its daily net investment income on
each day the Portfolio's net asset value per share is determined. Dividends are
payable monthly and are automatically reinvested and distributed on the last
business day of each month in full and fractional shares of the Portfolio at the
then-current net asset value unless a Shareholder requests payment in cash.
    
 
    Net investment income, for dividend purposes consists of (1) accrued
interest income, plus or minus (2) amortized purchase discount or premium, plus
or minus (3) all short-term realized gains or losses and unrealized appreciation
or depreciation on portfolio assets, minus (4) all accrued expenses of the
Portfolio. Expenses of the Portfolio are accrued daily. So long as the portfolio
securities are valued at amortized cost, there will be no unrealized
appreciation or depreciation on such securities.
 
HIGH GRADE BOND AND HIGH YIELD BOND PORTFOLIOS
 
   
    The Portfolios declare dividends of all their investment income on each day
the Portfolio's Net Asset Value is determined. Dividends are automatically
reinvested and distributed on the last business day of each month. Any
short-term and long-term gains will be declared and distributed periodically,
but in no event less frequently than annually.
    
 
OTHER PORTFOLIOS
 
   
    It is the policy of the Value Growth, Blue Chip and Managed Portfolios to
distribute at least annually substantially all their net investment income, if
any, and any net realized capital gains.
    
 
    Both dividend and capital gain distributions will be made in shares of such
Portfolio unless a Shareholder requests payment in cash.
 
                            PERFORMANCE INFORMATION
 
    As described in the Prospectus, a Portfolio's historical performance or
return may be shown in the form of "average annual total return" and "total
return" in the case of all Portfolios except the Money
 
                                       17
<PAGE>
Market Portfolio; "yield" in the case of the High Yield Bond and High Grade Bond
Portfolios; and "yield" and "effective yield" in the case of the Money Market
Portfolio. These various measures of performance are described below.
 
    Average annual total return and total return measure both the net income
generated by, and the effect of any realized and unrealized appreciation or
depreciation of, the underlying investments of a Portfolio over the specified
period. Yield is a measure of the net investment income per share earned over a
specific one-month or 30-day period (seven-day period for the Money Market
Portfolio) expressed as a percentage of the net asset value.
 
    A Portfolio's standardized average annual total return quotation is computed
in accordance with a method prescribed by rules of the Securities and Exchange
Commission. The standardized average annual total return for a Portfolio for a
specified period is determined by assuming a hypothetical $10,000 investment in
the Portfolio's shares on the first day of the period at the then effective net
asset value per share ("initial investment"), and computing the ending
redeemable value ("redeemable value") of that investment at the end of the
period. The redeemable value is then divided by the initial investment, and this
quotient is taken to the Nth root (N representing the number of years in the
period) and 1 is subtracted from the result, which is then expressed as a
percentage. The calculation assumes that all income and capital gains dividends
by the Portfolio have been reinvested at net asset value on the reinvestment
dates during the period. Standardized average annual total return figures for
various periods are set forth in the tables below.
 
    Calculation of a Portfolio's total return is not subject to a standardized
formula. Total return performance for a specific period is calculated by first
taking an investment (assumed to be $10,000) in the Portfolio's shares on the
first day of the period at the then effective net asset value per share
("initial investment") and computing the ending value ("ending value") of that
investment at the end of the period. The total return percentage is then
determined by subtracting the initial investment from the ending value and
dividing the difference by the initial investment and expressing the result as a
percentage. This calculation assumes that all income and capital gains dividends
by the Portfolio have been reinvested at net asset value on the reinvestment
dates during the period. Total return may also be shown as the increased dollar
value of the hypothetical investment over the period. Total return figures for
various periods are set forth in the tables below.
 
   
    The yield for a Portfolio other than the Money Market Portfolio is computed
in accordance with the formula set forth below, which is a standardized method
prescribed by rules of the Securities and Exchange Commission. Based upon the
30-day period ended December 31, 1996 the High Grade Bond Portfolio's yield was
6.76% and the High Yield Bond Portfolio's yield was 8.27%. A Portfolio's yield
is computed by dividing the net investment income per share earned during the
specific one-month or 30-day period by the offering price per share on the last
day of the period, according to the following formula:

      a =  dividends and interest earned during the period.

      c =  the average daily number of shares outstanding during the period that
           were entitled to receive dividends.
      d =  the offering price per share on the last day of the period.
</TABLE>
 
    In computing yield, the Fund follows certain standardized accounting
practices specified by Securities and Exchange Commission rules. These practices
are not necessarily consistent with those that the Fund uses to prepare its
annual and interim financial statements in accordance with generally accepted
accounting principles.
 
                                       18
<PAGE>
    The Money Market Portfolio's yield is computed in accordance with a standard
method prescribed by rules of the Securities and Exchange Commission. Under that
method, the yield quotation is based on a seven-day period and is computed as
follows. The net investment income per share (accrued interest on portfolio
securities, plus or minus amortized premium or discount, less accrued expenses)
for the period is divided by the price per share (expected to remain constant at
$1.00) at the beginning of the period ("base period return") and the result is
divided by seven and multiplied by 365 and the resulting yield figure is carried
to the nearest one hundredth of one percent. Realized capital gains or losses
and unrealized appreciation or depreciation of investments are not included in
the calculation.
 
    The Money Market Portfolio's effective yield is determined by taking the
base period return (computed as described above) and calculating the effect of
assumed compounding. The formula for the effective yield is [(base period return
+1) raised to the power of 365/7] -1.
 
   
    The Money Market Portfolio's yield and effective yield for the seven-day
period ending December 31, 1996 were 4.88% and 5.00%, respectively.
    
 
    A Portfolio's performance quotations are based upon historical results and
are not necessarily representative of future performance. The Fund's shares are
sold at net asset value, and return and net asset value will fluctuate except
that the Money Market Portfolio seeks to maintain a $1.00 net asset value per
share. Factors affecting a Portfolio's performance include general market
conditions, operating expenses and investment management. Shares of a Portfolio
are redeemable at net asset value, which may be more or less than original cost.
 
   
    The figures below show performance information for various periods ended
December 31, 1996. The rate of return for a Portfolio should be distinguished
from the rate of return of a corresponding subaccount of a separate account of a
Participating Insurance Company, whose rate will reflect the deduction of
additional charges, including a mortality and expense risk charge, and, if
calculated for corresponding periods, would be lower. VA contract and VLI
policyowners should consult the prospectus for such contract or policy.

                           SHAREHOLDER VOTING RIGHTS
 
    All shares of the Fund have equal voting rights and may be voted in the
election of Trustees and on other matters submitted to the vote of Shareholders.
As permitted by Massachusetts law, there will normally be no meetings of
Shareholders for the purposes of electing trustees unless and until such time as
fewer than a majority of the trustees holding office have been elected by
Shareholders. At that time, the Trustees then in office will call a
Shareholders' meeting for the election of Trustees. The Trustees must call a
meeting of Shareholders for the purpose of voting upon the question of removal
of any Trustee when requested to do so by the record holders of 10 percent of
the outstanding shares of the Fund. At such a meeting, a Trustee may be removed
after the holders of record of not less than two-thirds of the outstanding
shares of the Fund have declared that the Trustee be removed either by
declaration in writing or by votes cast in person or by proxy. Except as set
forth above, the Trustees shall continue to hold office and may appoint
successor Trustees, provided that immediately after the appointment of any
successor Trustee, at least two-thirds of the Trustees have been elected by the
Shareholders. The shares do not have cumulative voting rights, which means that
the holders of a majority of the shares voting for the election of Trustees can
elect all the Trustees. No amendment may be made to the Declaration of Trust
without the affirmative vote of a majority of the outstanding shares of the
Fund, except that amendments to conform the Declaration to the requirements of
applicable federal laws or regulations, or to the regulated investment company
provisions of the Internal Revenue Code, or to designate and
 
                                       20
<PAGE>
establish additional Portfolios, may be made by the Trustees without the vote or
consent of the Shareholders. If not terminated by the vote or written consent of
a majority of its outstanding shares, the Fund will continue indefinitely.
 
    In matters which only affect a particular Portfolio, the matter shall have
been effectively acted upon by a majority vote of that Portfolio even though:
(i) the matter has not been approved by a majority vote of any other Portfolio;
or (ii) the matter has not been approved by a majority vote of the Fund.
 
                                CONTROL PERSONS
 
    Farm Bureau Life Insurance Company ("Farm Bureau"), an Iowa corporation,
through its Variable Accounts will own all of the Fund's outstanding shares,
other than the shares of the Fund purchased for investment by Farm Bureau
through its general account to get the Portfolios of the Fund started and any
additional shares acquired by Farm Bureau through reinvestment of dividends on
those shares.
 
    Because Farm Bureau owns the shares of the Fund, the Fund is deemed to be
controlled by Farm Bureau by nature of the definitions contained in the
Investment Company Act of 1940. However, Farm Bureau will generally vote the
shares of the Fund held by the Variable Account in accordance with instructions
received from its VLI policyholders and VA contractholders. The shares held in
Farm Bureau's general account will generally be voted in proportion to voting
instructions received from Farm Bureau's VLI policyholders. Under certain
circumstances, however, Farm Bureau may disregard voting instructions received
from VLI policyholders.

ITEM 27.  INDEMNIFICATION.
 
    See Article XI, Section 2 of the Registrant's Declaration of Trust, filed as
Exhibit 1 to this Registration Statement, which provision is incorporated herein
by reference to post-effective amendment No. 1 filed on August 28, 1987.
 
    The Investment Advisory and Management Services Agreement between the
Registrant and the FBL Investment Advisory Services, Inc. ("Adviser") provides
that, in the absence of willful misfeasance, bad faith, gross negligence or
reckless disregard of obligations or duties thereunder on the part of the
Adviser, the Adviser shall not be liable for any error of judgment or mistake of
law, or for any loss suffered by the Fund in connection with the matters to
which such Agreement relates.
 
    In addition, the Registrant maintains a directors and officers "errors and
omissions" liability insurance policy under which the Registrant and its
trustees and officers are named insureds.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 ("Act") may be permitted to trustees, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a trustee, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
trustee, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act, and Registrant will be governed by the final
adjudication of such issue.
 
ITEM 28.  BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER.
 
    Registrant's investment adviser is FBL Investment Advisory Services, Inc.
("Adviser"). In addition to its services to Registrant as investment adviser,
underwriter and transfer and dividend disbursing agent, all as set forth in
parts A and B of this Registration Statement, the Adviser acts as adviser,
underwriter,
 
                                      C-3
<PAGE>
and shareholder service, transfer and dividend disbursing agent for FBL Money
Market Fund, Inc., a diversified open-end management investment company, and FBL
Series Fund, Inc., a diversified open-end series management investment company.
 
    The principal occupations of the principal executive officers and directors
of the Adviser are their services as officers, directors and/or employees of FBL
Financial Group, Inc. and the Iowa Farm Bureau Federation and/or its affiliates
as disclosed below. The address of FBL Financial Group, Inc. and the Federation
and its affiliates is 5400 University Avenue, West Des Moines, Iowa 50266.

vacancy created thereby, appointed an additional individual to serve as 
Trustee;

      WHEREAS, the Declaration of Trust as amended April 1, 1987, provided
