YIELD
INFORMATION
- ---------------
 
    From  time to time,  the Fund may  advertise its yield  and effective yield.
Each  figure  is  based  upon   historical  earnings  and  is  not   necessarily
representative  of the  future performance  of the Fund.  The yield  of the Fund
refers to the net  investment income generated by  a hypothetical investment  in
the  Fund over a specific  seven-day period. This net  investment income is then
annualized, which  means that  the net  investment income  generated during  the
seven-day  period is assumed to be generated each week over an annual period and
is shown as a  percentage of the investment.  The effective yield is  calculated
similarly,  but the net investment income earned by the investment is assumed to
be compounded  weekly when  annualized.  The effective  yield will  be  slightly
higher than the yield due to this compounding effect.
 
    The  performance of the Fund  may be compared to  that of other money market
mutual funds  tracked  by  Lipper  Analytical  Services,  Inc.,  an  independent
research  firm  which  ranks  mutual funds  by  overall  performance, investment
objectives and  assets, or  by IBC/Donoghue's  Money Fund  Directory, a  service
which reports on money market funds.
 
    The  Fund's yield and effective yield will fluctuate. Additional information
concerning the Fund's performance  is described in  the Statement of  Additional

INVESTMENT
OBJECTIVE
AND POLICIES
- ---------------
 
    The investment objective of  the Fund is  maximum current income  consistent
with  liquidity  and  stability of  principal  and  may not  be  changed without
shareholder approval.
 
    The Fund limits  its investments  to securities  that meet  the quality  and
diversification  requirements of Rule  2a-7 under the  Investment Company Act of
1940 (the "Investment Company Act"). Under Rule 2a-7, the Fund may only purchase
United States denominated  instruments that  are determined  to present  minimal
credit  risks and  at the time  of acquisition are  rated in the  top two rating
categories by the  required number of  nationally recognized statistical  rating
organizations  (at least  two or,  if only one  such organization  has rated the
security, that  one  organization) or,  if  unrated, are  deemed  comparable  in
quality.  The diversification requirements  of Rule 2a-7  provide generally that
the Fund may not at the time of acquisition invest more than 5% of its assets in
securities of any one issuer or invest more than 5% of its assets in  securities
that  have not  been rated  in the  highest category  by the  required number of
rating organizations or,  if unrated,  have not been  deemed comparable,  except
U.S. Government securities and repurchase agreements of such securities.
 
                                       4

    The  Fund seeks to achieve its objective by investing in the following money
market instruments  maturing  in  thirteen  months or  less  from  the  time  of
investment,  thereby  allowing the  Fund to  maintain a  dollar-weighted average
portfolio maturity of 90 days or less:
 
        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 depend solely upon the credit  of
    the agency or 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. The Fund  will not  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  Fund 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 Fund 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.  The Fund will
    only invest in  commercial paper  that is  rated A-1  or A-2  by Standard  &
    Poor's  Corporation  ("S&P")  or  Prime-1 or  Prime-2  by  Moody's Investors
    Service, Inc. ("Moody's") or, if unrated, issued by a corporation having  an
    outstanding debt issue rated at least AA/Aa by S&P or Moody's.
 
        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 above 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 Directors, 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
 
                                       5
<PAGE>
    months  or less  remaining to  maturity. The Fund  will only  invest in such
    obligations that at the time of purchase are rated AA/Aa or better by S&P or
    Moody's.
 
        REPURCHASE AGREEMENTS:   A repurchase agreement  is an instrument  under
    which  the Fund acquires a security from  the seller who agrees, at the time
    of the sale, to repurchase the  security at a predetermined time and  price,
    thereby  determining the yield during the  Fund's holding period. That yield
    is established by reference to current  short-term rates and may be more  or
    less  than the interest  rate on the  underlying security. The  value of the
    underlying  security  is  marked-to-market  daily.  If  the  value  of   the
    underlying  security declines, the  seller would be  required to provide the
    Fund  with  additional  securities  so  that  the  aggregate  value  of  the
    underlying securities was at least equal to the repurchase price.
 
        The  Fund may  also enter  into a  special type  of repurchase agreement
    known as an "open repurchase agreement." An open repurchase agreement varies
    from the typical agreement in the following respects: (1) the agreement  has
    no  set maturity, but instead  matures upon 24 hours'  notice to the seller;
    and (2) 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.
 
        Repurchase agreements maturing in more  than seven days will not  exceed
    10% of the net assets of the Fund, and no more than 25% of the net assets of
    the  Fund may be  invested in repurchase agreements  in which the underlying
    securities have maturities in excess of one year, although there is no limit
    to the percentage of the Fund's  assets which may be invested in  repurchase
    agreements  that mature in seven days or less and have underlying securities
    with maturities of one year or less. Net assets are taken at market value at
    the time  of  purchase  for  purposes of  the  foregoing  limitations.  Open
    repurchase agreements are considered to mature in one day.
 
        If  a seller of a  repurchase agreement were to  default, the Fund 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
    Directors) will review  the creditworthiness  of the seller,  and must  find
    such  creditworthiness  satisfactory  before  the Fund  may  enter  into the
    repurchase agreement. Repurchase agreements may  be entered into with  banks
    or  securities dealers  and the underlying  securities will  consist only of
    securities issued  or guaranteed  by the  U.S. Government,  its agencies  or
    instrumentalities.
 
        FLOATING  AND  VARIABLE  RATE  SECURITIES:    The  Fund  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   Fund
 
                                       6
<PAGE>
    determines the  maturity  of Variable  Rate  Securities in  accordance  with
    Securities  and Exchange Commission  rules which allow  the Fund to consider
    certain of such instruments as  having maturities shorter than the  maturity
    date on the face of the instrument.
 
        WHEN-ISSUED OR DELAYED DELIVERY TRANSACTIONS:  From time to time, in the
    ordinary  course of business, the  Fund may purchase newly-issued securities
    on a "when-issued" basis and may  purchase or sell securities on a  "delayed
    delivery"  basis.  When-issued or  delayed  delivery transactions  involve a
    commitment by  the  Fund to  purchase  or sell  particular  securities  with
    payment  and delivery  to take  place at  a future  date. These transactions
    allow the  Fund to  lock  in an  attractive purchase  price  or yield  on  a
    security it intends to purchase or an attractive sale price on a security it
    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 the  Fund  and, for  delayed  delivery
    purchases,  no  interest  accrues  to  the Fund.  The  Fund  will  only make
    commitments to  purchase securities  on a  when-issued or  delayed  delivery
    basis  with  the  intention of  actually  acquiring the  securities,  but it
    reserves the right  to sell such  securities before the  settlement date  if
    deemed advisable.
 
        At  the time the Fund  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 value of the security in determining its net
    asset value. Likewise, at the time the  Fund 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.  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  the Fund  engages in  when-issued  or
    delayed delivery transactions, it will do so for the purpose of acquiring or
    selling  securities consistent  with its 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 the Fund's net asset value
    or income will be adversely affected  overall by the purchase of  securities
    on  a  when-issued or  delayed  delivery basis.  The  Fund will  establish a
    segregated account with its 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, the Fund may  purchase
    securities  on a when-issued or delayed delivery basis without limit. To the
    extent that assets of the Fund are held in cash pending the settlement of  a
    purchase  of securities,  the Fund would  earn no  income. In the  case of a
    commitment to sell  securities on a  delayed delivery basis,  the Fund  will
    instruct  the  custodian  to  hold  the  Fund  securities  themselves  in  a
    segregated account while the commitment is outstanding.
 
   
    Stability of principal is  a primary investment objective  of the Fund  and,
while  the types of money market securities  in which the Fund invests generally
are considered to have  low principal risk, such  securities are not  completely
risk free. There is some risk that issuers will fail to meet their principal and
interest obligations on a timely basis; therefore there can be no guarantee that
the  Fund will achieve its objective or that  it will maintain a net asset value
of $1.00 per share. The  net asset value of $1.00  per share has, however,  been
maintained  by the Fund since its inception.  Thus, no shareholder has ever lost
any principal from an investment in the Fund.
    
 
    The Fund has adopted a number  of restrictions and policies relating to  the
investment  of its assets and its activities that are fundamental and may not be
changed without the approval of the holders of a
 
                                       7
<PAGE>
"majority of the Fund's outstanding voting  securities" as such term is  defined
in  the Investment  Company Act  of 1940.  A complete  list of  these investment
restrictions and policies  is contained  in the Fund's  Statement of  Additional
Information.

                                                                          REDEEM

                                                                       ---------
 
   
    Upon receipt of an executed redemption  request in proper form as  described
below, the Fund will redeem shares at their next determined net asset value. The
Fund intends to pay redemption proceeds within one business day after receipt of
an  executed redemption request  in proper form.  If shares to  be redeemed were
purchased by check, the Fund may delay transmittal of redemption proceeds  until
it  has determined that the check has cleared, which may take up to 15 days from
the purchase  date. SHAREHOLDERS  MAY NOT  USE EXPEDITED  REDEMPTION  PROCEDURES
(DRAFT  OR TELEPHONE  REDEMPTION) IF  SHARES WERE  PURCHASED BY  CHECK UNTIL THE
SHARES BEING REDEEMED  HAVE BEEN ON  THE FUND'S  BOOKS FOR AT  LEAST 4  BUSINESS
DAYS. There is no such delay when redeeming shares that were purchased by wire.
    
 
    Due  to the high cost  of maintaining small accounts,  the Fund reserves the
right to redeem an account which an investor has reduced to a value of less than
$500. A shareholder will be notified  accordingly and permitted 60 days to  make
additional share purchases before the liquidating redemption is processed.
 
By Mail (no minimum):
 
    Send  a letter to the Fund, 3820  109th Street, Des Moines, Iowa 50391-7003,
requesting redemption  of either  the number  or dollar  value of  shares to  be
redeemed.  The letter must be signed exactly  as the account is registered. On a
jointly owned account, all owners must  sign. SIGNATURES OF ACCOUNT OWNERS  MUST
BE  GUARANTEED BY A COMMERCIAL BANK, TRUST  COMPANY, MEMBER OF A STOCK EXCHANGE,
SAVINGS  AND  LOAN  ASSOCIATION  OR  SAVINGS  BANK,  OTHER  ELIGIBLE   FINANCIAL
INSTITUTION,  OR A REGISTERED REPRESENTATIVE OF  FBL MARKETING SERVICES, INC. OR
FBL  INVESTMENT  ADVISORY   SERVICES,  INC.,  and   shall  include  such   other
documentation  of authority as the Fund deems  necessary in the case of estates,
trusts, guardianships, corporations, unincorporated associations and pension and
profit sharing plans. THE FUND CANNOT ACCEPT GUARANTEES FROM NOTARIES PUBLIC.
 
By Draft (no minimum):
 
    A shareholder may  redeem shares  by writing  drafts drawn  on Norwest  Bank
Iowa,  N.A., payable  to the order  of any  person in any  amount. A shareholder
wishing to use this method of  redemption must complete the appropriate  portion
of  the Application  including a  signature card. Drafts  can be  ordered by the
shareholder, for a charge of $12.00 per 175 drafts ordered, after all  necessary
application  forms have  been received  in proper form.  The cost  of the drafts
ordered by  the  shareholder will  be  collected  by redemption  of  shares,  or
fractions  thereof, from  the shareholder's  account. If  the entire  account is
redeemed by draft, dividends credited to that account from the beginning of  the
month  through the day of redemption will be  paid by a separate check mailed to
the address of record. Payment of drafts  is subject to acceptance by the  Fund,
and  the Fund may  refuse to honor  drafts whenever the  right of redemption has
been suspended or postponed, or whenever the shareholder's account is  otherwise
impaired.  When the  draft is presented  for payment and  accepted, a sufficient
number of shares in the account will be redeemed to pay the amount of the draft.
When a draft is presented  to redeem Fund shares in  excess of the value of  the
account OR TO REDEEM SHARES PURCHASED BY CHECK WITHIN 4 BUSINESS DAYS, the draft
will be returned marked "insufficient funds" and a service charge of $10.00 will
be  levied on  all drafts so  marked. Redemption  by draft is  not available for
Retirement Accounts.
 
                                       9
<PAGE>
    Copies or  cleared  drafts  may be  obtained  by  calling the  Fund  at  our
toll-free  number (800) 247-4170  (in Iowa call toll-free  (800) 422-3175, or in
the Des Moines metropolitan area call 225-5586),  or by writing a letter to  the
Fund.  The first five copies of drafts per year will be provided at no charge to
the shareholder; thereafter, there will be a charge of $3 per copy. The costs of
the copies will be collected by redemption of shares, or fractions thereof, from
the shareholder's account.
 
By Telephone ($1,000 minimum):
 
    Shareholders may  redeem shares  by  telephone. The  proceeds of  shares  so
redeemed  will be sent by  check to the shareholder of  record at the address of
record. A shareholder wishing to use this method of redemption must complete the
appropriate portions of the Application  and it must be  on file with the  Fund.
All  applications for telephone redemption must  have signatures guaranteed by a
commercial bank, trust  company, member of  a stock exchange,  savings and  loan
association  or  savings  bank,  other  eligible  financial  institution,  or  a
registered representative  of FBL  Marketing Services,  Inc. or  FBL  Investment
Advisory Services, Inc., and shall include such other documentation of authority
as  the  Fund deems  necessary in  the case  of estates,  trusts, guardianships,
corporations, unincorporated associations and pension and profit sharing  plans.
THE  FUND CANNOT ACCEPT GUARANTEES FROM NOTARIES PUBLIC. Once the completed form
is on file, the Fund will honor redemption requests by ANY PERSON by  telephone,
using the toll free numbers listed on the cover page, telegraph or other methods
without a signature guarantee from the shareholder or any other person. Proceeds
may  also be paid to the shareholder by  wire transfer, but only to the bank and
account on  file as  designated by  the shareholder,  which must  be a  domestic
commercial  bank that is  a member of  the Federal Reserve  System. Although the
Fund does not charge for wiring  funds, the shareholder will be responsible  for
wire fees, if any, charged by the receiving bank. The Adviser employs procedures
designed  to confirm  that instructions  communicated by  telephone are genuine,
including  requiring  certain  identifying  information  prior  to  acting  upon
instructions,   recording  all   telephone  instructions   and  sending  written
confirmations of  instructions. To  the extent  such procedures  are  reasonably
designed  to prevent unauthorized or fraudulent instructions neither the Adviser
nor the Fund  would be  liable for any  losses from  unauthorized or  fraudulent
instructions. The Fund reserves the right to terminate this telephone redemption
privilege at any time. This procedure is not available for Retirement Accounts.

OTHER
SHAREHOLDER
SERVICES
- ----------------
 
    The  Fund offers  a number  of shareholder  services designed  to facilitate
investment in its shares. Full details as to each of such services and copies of
the various plans described below can be obtained from the Fund.
 
   
PERIODIC WITHDRAWAL PLAN
    
 
   
    A shareholder who owns $5,000 or more of Fund shares in a single account may
establish a Periodic Withdrawal Plan  to provide for regular monthly,  quarterly
or  annual payments  of a fixed  dollar amount  or fixed percent  of the account
balance ($100 annual  minimum) to  be sent to  the shareholder  or a  designated
payee.  (Account balance and withdrawal limitations may be waived if the plan is
established using  life  expectancy  factors to  calculate  a  required  minimum
distribution.)  Fund shares held in the shareholder's account having a net asset
value of the amount of the requested payment will be
    
 
                                       10
<PAGE>
redeemed on or around the  fifth business day before  the end of the  applicable
month and a check will be mailed to the investor within seven days thereafter.
 
   
AUTOMATIC INVESTMENT PLAN
    
 
   
    A  shareholder may elect  to participate in  the Fund's automatic investment
plan. This plan enables  a shareholder to automatically  purchase shares of  the
Fund  on a  monthly basis. A  minimum initial  investment of $50  per account is
required to establish an automatic investment plan. Minimum monthly  investments
of  $25 per account are necessary to maintain  the plan. The Fund will debit the
shareholder's financial institution account and subsequently purchase shares  of
the  Fund having a net asset value of  the amount of the requested deposit on or
around the 16th  day of  the month. Shareholders  interested in  this plan  must
complete  an automatic investment form available from the Fund. If a shareholder
has elected to participate in the  Automatic Investment Plan, and all shares  of
an  account with that  option are exchanged  for shares of  any portfolio of FBL
Series Fund,  Inc.,  the  Automatic  Investment Plan  will  continue  under  the
account(s)  to which the shares were exchanged,  until such time as that fund is
notified in writing to discontinue the Plan.
    
 
   
EXCHANGE PRIVILEGE
    
 
   
    A shareholder  may  exchange all  or  some Fund  shares  for shares  of  any
portfolio   of  FBL  Series   Fund,  Inc.,  provided   the  accounts  have  like
registrations, if that fund's shares are eligible for sale in the  shareholder's
state of residence. FBL Series Fund, Inc. currently offers six portfolios: Value
Growth  Portfolio, High Grade Bond Portfolio, High Yield Bond Portfolio, Managed
Portfolio, Money Market Portfolio and Blue Chip Portfolio. A prospectus for  FBL
Series  Fund, Inc. may be  obtained by writing or calling  that fund at the same
address or  phone  numbers  as shown  on  the  cover page  of  this  prospectus.
Traditional  Shares  of that  fund are  subject to  a contingent  deferred sales
charge of up to  5%, as described  in its prospectus. Exchanges  may be for  any
amount,  except that if a new account  is established by the exchange privilege,
an application for that account  must be completed and  mailed to the fund,  and
the  minimum  initial purchase  amount  must be  met.  Exercise of  the exchange
privilege is treated as a sale for federal income tax purposes and, depending on
the  circumstances,  a  gain  or  loss  may  be  realized  by  the  shareholder.
Shareholders  of the Fund  interested in exercising  the exchange privilege must
first obtain a prospectus and an exchange form from the Fund. Once the completed
exchange form is on file with the Fund, exchanges may be authorized by telephone
(by ANY PERSON) or by  letter. This privilege may  be modified or terminated  by
the Fund at any time.
    
 
    A  shareholder may  also request  exchanges to  any portfolio  of FBL Series
Fund, Inc.  on  a  monthly  or quarterly  basis  using  the  automatic  exchange
privilege. Automatic exchanges occur on the 20th day of the month of the elected
schedule  or the following business day if the 20th is a holiday or weekend day.
Shareholders interested in the automatic exchange privilege must first obtain  a
prospectus  and an automatic  exchange form from  that fund. Automatic exchanges
are subject to the considerations listed in the above paragraph.
 
   
RETIREMENT PLANS
    
 
   
    Eligible shareholders of the Fund may participate in a variety of  qualified
retirement plans which are available from FBL Investment Advisory Services, Inc.
Some  of the  plans currently  offered are:  Self-Employed Individual Retirement
Plans (Keogh Plans), Individual Retirement Accounts (IRAs), Simplified  Employee
Pension  Plans  (SEPs), Savings  Incentive Match  Plans for  Employees (SIMPLEs)
retirement plans,  Tax  Sheltered 403(b)  Plans,  Corporate Pension  and  Profit
Sharing  Plans,  and Public  Employer Deferred  Compensation Plans.  The initial
investment to establish any such plan, and subsequent investments, may be in any
amount (subject to plan limitations). Investors Fiduciary Trust Company ("IFTC")
of Kansas City, Missouri serves as custodian and provides the required  services
for  Keogh Plans, IRAs,  SEPs, SIMPLEs and Corporate  Pension and Profit Sharing
Plans. A custodial fee, currently $10.00, will
    
 
                                       11
<PAGE>
be collected annually by redemption of  shares, or fractions thereof, from  each
participant's  account(s). FBL Investment Advisory  Services, Inc. performs plan
services for IFTC for a  portion of the fee.  Information with respect to  these
plans is available upon request from the Fund.
 
    Trustees  of qualified retirement plans and 403(b)(7) custodial accounts are
required by law to withhold 20% of the taxable portion of any distribution  that
is  eligible to be "rolled over." The 20% withholding requirement does not apply
to distributions from IRAs  or any part of  a distribution which is  transferred
directly  to  another  qualified  retirement  plan,  403(b)(7)  account  or IRA.
Shareholders should consult  their tax advisers  regarding this 20%  withholding
requirement.

NET
ASSET
VALUE
- -------
 
   
    The net asset value per share of the Fund 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
the  Exchange is open  (except the Fridays after  Christmas Day and Thanksgiving
Day) and on each other  day on which there is  sufficient trading in the  Fund's
investments  that it might affect the net asset value, except that the net asset
value will not be computed on a day when no orders for purchase or redemption of
shares are  received.  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 the emergency closed  day,
then  the Fund will  price those orders  and redemptions at  the net asset value
next determined. The net asset value per share is computed by dividing the total
value of the  Fund's securities  and other assets,  less liabilities  (including
dividends  payable), by the number of Fund shares outstanding. The Fund seeks to
maintain a constant net asset value per share of $1.00. The Fund's total  assets
are determined by valuing the portfolio securities at amortized cost pursuant to
Rule 2a-7 under the Investment Company Act.

                                                                    TRANSACTIONS

    Purchases   and  sales  of  portfolio   securities  are  normally  principal
transactions. Portfolio  securities are  normally  purchased directly  from  the
issuer  or from  an underwriter  or market maker  for the  securities. There are
usually no brokerage commissions  paid by the Fund  for such purchases and  none
were   paid  during  the  fiscal  year  ended  July  31,  1997.  Purchases  from
underwriters will include a commission or  concession paid by the issuer to  the
underwriter,  and purchases  from dealers serving  as market  makers include the
spread between  the  bid and  asked  price.  The primary  consideration  in  the
allocation of transactions is the most favorable price and execution of orders.

                                                                       DIVIDENDS
                                                                     -----------
 
    The  Fund declares dividends of all its  daily net investment income on each
day the Fund'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 Fund at the then  current
net  asset  value,  unless a  shareholder  requests payment  in  cash; provided,
however, that no cash payment will be made for dividends in an amount under $10.
Any such dividend amount under $10 will be reinvested in shares of the Fund.
 
                                       13
<PAGE>
   
    If a  shareholder  has elected  to  receive dividends  and/or  capital  gain
distributions  in cash,  from an  account that remains  open, and  the postal or
other delivery service is  unable to deliver those  monies to the  shareholder's
address  of record, such shareholder's distribution option will automatically be
converted  to  having  all  dividend  and  other  distributions  reinvested   in
additional  shares, and the  outstanding check will be  voided and reinvested in
the account. If a  shareholder has elected to  receive dividends and/or  capital
gain distributions in cash, from an account that is subsequently closed, and the
postal   or  other  delivery  service  is   unable  to  deliver  checks  to  the
shareholder's address of record, such check will remain outstanding until it  is
turned  over to the  appropriate state agency for  escheat purposes. No interest
will accrue  on  amounts  represented by  uncashed  distribution  or  redemption
checks.
    
 
    Each  non-qualified account  shareholder will  receive a  monthly summary of
account  activity,  including  information  on  dividends  paid  or  reinvested.
Qualified  account shareholders  will receive  a quarterly  statement reflecting
dividend activity. If the entire  amount in an account  is redeemed at any  time
during  a month, dividends  credited to that  account from the  beginning of the
month through the day of redemption will be paid in addition to the proceeds  of
the redemption.
 
    The  Fund's net  investment income, for  dividend purposes,  consists of (1)
accrued interest income, plus or  minus amortized purchase discount or  premium,
(2)  plus  or  minus all  short-term  realized  gains or  losses  and unrealized
appreciation or  depreciation on  portfolio assets,  and (3)  minus all  accrued
expenses  of the Fund.  Expenses of the Fund  are accrued daily.  So long as the
Fund's portfolio  securities are  valued at  amortized cost  there would  be  no
unrealized appreciation or depreciation on portfolio securities.
 
- --------------------------------------------------------------------------------
TAXES
- ------
 
    The  Fund intends to  continue to qualify as  a regulated investment company
under the Internal Revenue Code of 1986,  as amended. If so qualified, the  Fund
will  not be subject to  federal income taxes to  the extent that it distributes
its taxable investment income  and realized gains.  Distributions of net  income
including  any  net  short-term capital  gains  are taxable  to  shareholders as
ordinary income, whether such distributions are  taken in cash or reinvested  in
additional shares. Of course, such distributions are not taxable to shareholders
who  are not subject to  income tax. Distributions from  the Fund do not qualify
for the  "dividends received  deduction"  available to  corporate  shareholders.
Distributions  declared  in October,  November  or December  to  shareholders of
record as of a date in one of those months and paid during the following January
are treated  for federal  income tax  purposes as  paid on  December 31  of  the
calendar  year in which declared. Shareholders are advised to consult with their
tax adviser. Statements as  to the tax status  of distributions to  shareholders
will be furnished to shareholders annually.
 
    The  Fund is  required by  law to withhold  31% of  taxable distributions to
shareholders who  do  not furnish  their  correct social  security  or  taxpayer
identification number and in certain other circumstances.

ORGANIZATION OF THE FUND
 
    The  Fund is a no-load,  open-end, diversified management investment company
incorporated under Maryland  law on November  5, 1980. The  Fund has  authorized
capital  of 500,000,000 shares of capital stock, $0.001 par value per share. All
shares of capital stock have equal  voting rights and equal rights with  respect
to  dividends,  assets,  liquidation and  redemption.  They are  fully  paid and
non-assessable when  issued  and  have no  preemptive,  conversion  or  exchange
rights.  The shares  are transferable  without restriction.  Full and fractional
shares may be  issued and  each fractional  share has  proportionately the  same
rights, including voting, as are provided for a full share.
 
SHAREHOLDER VOTING RIGHTS
 
    Under  the Fund's corporate charter and by-laws, the Fund is not required to
hold, and does not anticipate that it will hold, annual shareholders'  meetings.
However,  it will  hold special meetings  of shareholders as  required or deemed
desirable for such purposes as electing directors, changing fundamental policies
or approving an investment management agreement.
 
    Each member  of  the Board  of  Directors serves  for  a term  of  unlimited
duration, subject to the right to remove a Director by the Board of Directors or
the  shareholders. The Board of  Directors has the power  to alter the number of
directors and to  appoint successor directors,  provided that immediately  after
the  appointment of any successor director, at least two-thirds of the directors
have been elected by the shareholders of the Fund. However, if at any time  less
than  a  majority  of the  directors  holding  office has  been  elected  by the
shareholders,  the  directors  are  required  to  call  a  special  meeting   of
shareholders  for  the  purpose  of  electing  directors  to  fill  any existing
vacancies on the Board.
 
    As used in this Prospectus and  in the Statement of Additional  Information,
the phrase "majority of the Fund's outstanding voting securities" means the vote
of  the lesser of (i) 67% of the shares  of the 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 Fund.
 
REPORTS TO SHAREHOLDERS
 
    Shareholders  will  receive unaudited  semi-annual financial  statements and
fiscal year-end financial statements audited by the Fund's independent auditors.
 
SHAREHOLDER INQUIRIES
 
   
    Shareholders may  make  inquiries  either  by  contacting  their  registered
representative or by writing or calling the Fund at the address or phone numbers
as  shown  on the  front cover.  Copies  of year-end  account statements  may be
obtained by calling  the Fund at  our toll-free number  (800) 247-4170 (in  Iowa
call  toll-free  (800) 422-3175,  or in  the Des  Moines metropolitan  area call
225-5586), or by  writing a letter  to the  Fund. The prior  year statement  for
regular  accounts, and prior two year statements for fiduciary accounts, will be
provided at no charge to the shareholder; thereafter, there will be a charge  of
$3  per copy. The costs of the copies will be collected by redemption of shares,
or fractions  thereof,  from the  shareholder's  account. If  the  shareholder's
account has been closed, the applicable fees must be remitted with the request.

                            INVESTMENT RESTRICTIONS
 
    In seeking to achieve its investment objective as stated in the  Prospectus,
the Fund has adopted the following investment restrictions. The Fund will not:
 
        1.   Purchase securities of any  issuer (other than securities issued or
    guaranteed by the U.S. Government, its agencies or instrumentalities) if, as
    a result, more than 5% of the  value of the Fund's assets (taken at  current
    value  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  securities issued  or guaranteed  by  the U.S.  Government, its
    agencies or  instrumentalities.  (For  this purpose,  all  outstanding  debt
    securities of an issuer are considered one class.)
 
        3.    Engage  in  puts, calls,  straddles,  spreads  or  any combination
    thereof; nor  engage  in margin  purchases,  except for  use  of  short-term
    credits  necessary  for  clearance  of  purchases  and  sales  of  portfolio
    securities.
 
        4.   Make short  sales of  securities or  maintain a  short position  in
    securities.
 
        5.  Invest in real estate, including interests in real estate investment
    trusts  (although  it may  invest in  securities secured  by real  estate or
    interests therein or  securities issued  by companies which  invest in  real
    estate   or  interests  therein)  or  invest  in  commodities  or  commodity
    contracts, including futures contracts.
 
        6.  Invest more than 5% of  the value of the Fund's total assets  (taken
    at  current value at the time of investment) in securities of issuers, other
    than securities issued or guaranteed by the U.S. Government, its agencies or
    instrumentalities, which have a record  of less than three years  continuous
    operations, including predecessors.
 
        7.    Purchase or  retain the  securities of  any issuer  if any  of the
    officers or directors of the Fund or its investment adviser own individually
    more than 1/2 of 1% of the  securities of such issuer and together own  more
    than 5% of the securities of such issuer.
 
        8.   Concentrate its investments in any one industry by investing 25% or
    more of the value of the Fund's total assets (taken at current value at  the
    time  of investment)  in any one  industry, other than  securities issued or
    guaranteed by  the U.S.  Government or  its agencies  or  instrumentalities,
    obligations  of  banks or  savings institutions,  or instruments  secured by
    these money  market  instruments, such  as  repurchase agreements  for  U.S.
    Government securities.
 
        9.    Make  loans  to  others  (except  through  the  purchase  of  debt
    obligations or repurchase agreements referred to under "Investment Objective
    and Policies" in the Prospectus). In addition, the Fund may not invest  more
    than  10%  of  its  net  assets  (taken at  current  value  at  the  time of
    investment) in repurchase agreements maturing in more than seven days.
 
        10. Borrow money, except from banks for temporary or emergency  purposes
    and  in no event in excess of 10% of its gross assets taken at the lesser of
    cost or market or  other fair value  (the Fund will not  borrow in order  to
    increase income (leveraging) but may borrow to facilitate meeting redemption
    requests  which might  otherwise require  untimely disposition  of portfolio
    securities; interest paid on any such borrowings will reduce net  investment
    income);  nor will it pledge  or mortgage more than  15% of its gross assets
    taken at cost,  except in connection  with permissible borrowings  discussed
    immediately  above;  nor purchase  money market  instruments while  any such
    permissible borrowings are outstanding.
 
        11. Act as an  underwriter in securities. In  this connection, the  Fund
    will not invest more than 10% of the value of its total assets in securities
    (except  repurchase agreements)  which are  subject to  legal or contractual
    restrictions on resale, or are not readily marketable.
 
        12.  Purchase  securities  of  other  investment  companies,  except  in
    connection with a merger, consolidation, acquisition or reorganization.
 
                                      B-2
<PAGE>
        13.  Invest in  companies for  the purpose  of exercising  management or
    control.
 
        14. Purchase any common stocks or other equity securities, or securities
    convertible into stock.
 
        15. Issue senior securities.
 
    The investment restrictions described above  are fundamental and may not  be
changed  without the approval of the lesser of (i) 67% of the shares represented
at the meeting of the  shareholders at which the holders  of 50% or more of  the
shares  are represented  in person  or by  proxy or  (ii) more  than 50%  of the
outstanding voting securities.
 
    In addition, the Fund may not: (a) purchase securities which are subject  to
legal  or contractual restrictions on resale in excess of 5% of the value of the
Fund's net  assets;  (b)  invest in  interests  in  oil, gas  or  other  mineral
exploration  or development  programs or  invest in  oil, gas,  or other mineral
leases; (c)  pledge, mortgage  or hypothecate  its portfolio  securities to  the
extent that at any time the percentage of pledged securities would exceed 10% of
the  Fund's total net assets; or (d) invest in real estate limited partnerships.
These restrictions, (a) through  (d), may be changed  by the Board of  Directors
without shareholder approval.

                       INVESTMENT OBJECTIVE AND POLICIES
 
    The  following  information supplements  the  information set  forth  in the
Prospectus under the caption "INVESTMENT OBJECTIVE AND POLICIES."
 
    It is  the Fund's  intention, as  a general  policy, to  hold securities  to
maturity. Nevertheless, the Fund may sell portfolio securities prior to maturity
in  order to realize gains or losses or  to shorten the average maturity and may
reduce or withhold dividends if it deems such actions appropriate to maintain  a
stable net asset value. In addition, the Fund may attempt, from time to time, to
increase its yield by trading to take advantage of variations in the markets for
short-term  money  market instruments.  Redemptions  of Fund  shares  could also
necessitate the sale of portfolio securities at times when such sales would  not
be  otherwise desirable. While the Fund intends  to invest in high quality money
market instruments, these investments are not entirely without risk. An increase
in interest rates will generally reduce the market value of the Fund's portfolio
investments and a decline in interest rates will generally increase the value of
the Fund's portfolio investments. Securities which are not issued or  guaranteed
by  the U.S. Government are subject to the possibility of default by the issuer.
Those  obligations  having  the  maximum   degree  of  security  tend  to   have
proportionately  lower  yields.  Since the  Fund's  assets will  be  invested in
securities with  short maturities  and the  Fund will  manage its  portfolio  as
described above, the Fund's
 
                                      B-6
<PAGE>
   
portfolio of money market instruments may be expected to turn over several times
a year. Since securities with maturities of less than one year are excluded from
required portfolio turnover calculations, the Fund's portfolio turnover rate for
reporting  purposes is zero. Of course, there  can be no assurance that the Fund
will achieve its objective.
    
 
                                NET ASSET VALUE
 
   
    The net asset value per share of the Fund is determined as of the earlier of
the close of the New  York Stock Exchange or 3:00  p.m. (Central Time), on  each
day  the Exchange is open  for business, except the  Fridays after Christmas Day
and Thanksgiving Day,  and on  each other  day on  which there  is a  sufficient
degree  of trading in the Fund's investments  that it might affect the net asset
value, except that the  net asset value will  not be computed on  a day when  no
orders  for purchase or redemption  of shares are received.  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
the emergency closed day, then the Fund will price those orders and  redemptions
at  the net asset value next determined.  The Fund's net asset value is computed
by dividing the  total value  of the Fund's  securities and  other assets,  less
liabilities  (including  dividends  payable),  by  the  number  of  Fund  shares
outstanding. The net asset value per share is ordinarily $1.00. The Fund's total
assets are determined  by valuing  the portfolio securities  at amortized  cost,
pursuant  to Rule  2a-7 under  the Investment  Company Act  of 1940.  While this
method provides certainty in  valuation, it may result  in periods during  which
the  value, as determined by  amortized cost, is higher  or lower than the price
the Fund would receive if it sold its portfolio securities. Under the  direction
of  the Board of Directors, certain procedures  have been adopted to monitor and
stabilize the price per share. Calculations are made to compare the value of the
Fund's portfolio valued at amortized cost with market values. Market  valuations
are  obtained by using actual quotations provided by market makers, estimates of
market value, or values  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 were
to occur between the Fund's  $1.00 per share net asset  value and the net  asset
value  calculated by reference to market valuations,  or if there were any other
deviation which the  Board of  Directors believed  would result  in dilution  or
other  unfair  results  material to  shareholders  or purchasers,  the  Board of
Directors would promptly consider what action, if any, should be initiated.  The
Fund  reserves  the right  to calculate  or  estimate the  net asset  value more
frequently than once a day if deemed desirable.
    
 
    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  increases; and  when
yields  increase, the market value of the portfolio invested at lower yields can
be expected to decline. In addition, if  the Fund has net redemptions at a  time
when  interest  rates  have  increased,  the Fund  may  have  to  sell portfolio
securities prior to maturity at a  price below the Fund's carrying value.  Also,
because  the portfolio  generally will be  valued at amortized  cost rather than
market, any yield quoted may be different if the entire portfolio were valued at
market  since   amortized  cost   does  not   take  market   fluctuations   into
consideration.
 
                          CALCULATION OF FUND'S YIELD
 
   
    The Fund'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 Fund's
net investment income per share (accrued interest on portfolio securities,  plus
or minus amortized premium or discount, less accrued expenses) 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. 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 Fund's
yield for the seven-day period ended July 31, 1997 was 4.04%.
    
 
                                      B-7
<PAGE>
   
    The Fund's effective yield  is determined by taking  the base period  return
(computed  as  described  above)  and  calculating  the  effect  of  the assumed
compounding. The formula for the effective  yield is (base period return +1)  to
the  power of (365/7) -  1. The Fund's effective  yield for the seven-day period
ended July 31, 1997 was 4.12%.
    
 
    The Fund's  yield fluctuates,  and the  publication of  an annualized  yield
quotation  is not  a representation as  to what  an investment in  the Fund will
actually yield for any given future  period. Actual yields will depend not  only
on  changes in interest rates  on money market instruments  during the period in
which the  investment in  the Fund  is held,  but also  on such  matters as  any
realized  gains and losses, unrealized appreciation and depreciation and changes
in Fund expenses.
 
                                RETIREMENT PLANS
 
    The  Fund  offers  a  variety  of  retirement  investment  programs  whereby
contributions are invested in shares of the Fund, and any dividends (and capital
gain  distributions, if  any) are reinvested  in additional  full and fractional
shares of the Fund. The Fund  has waived the minimum investment requirement  for
an  account opened under any of these programs and subsequent investments can be
in any amount (subject to plan limitations).
 
SELF-EMPLOYED INDIVIDUAL RETIREMENT PLANS
 
   
    The Fund  has  available for  self-employed  individuals a  form  of  Paired
Defined  Contribution  Plan,  Trust Agreement  and  related  Custodial Agreement
(Keogh Plan)  under  IRS approved  prototypes.  A self-employed  individual  has
complete  discretion to make his or her  own fee arrangements with the custodial
bank of his or her selection, instead of using the custodian named herein on the
terms described under "General"  below. The maximum  annual amount permitted  as
deductible  contributions is generally  the lesser of 25%  of earned income from
self-employment or  $30,000. For  purposes  of the  25%  limit of  the  previous
sentence,  currently no more  than $160,000 of earned  income may be considered.
The $160,000  limit is  increased from  time to  time by  the Secretary  of  the
Treasury  to take  into account  increases in  the cost  of living.  For further
details, including the right of appointing  a successor custodian, refer to  the
Plan, Trust Agreement and Custodial Agreement available from the Fund.
    
 
INDIVIDUAL RETIREMENT ACCOUNTS
 
   
    The  Fund  has available  Individual  Retirement Accounts  (IRAs)  under IRS
approved prototypes. A full $2,000 deduction for IRA contributions is  available
only  to (1) taxpayers who are  not active participants in an employer-sponsored
retirement plan and (2)  taxpayers who are active  participants in an  employer-
sponsored  plan, but  have adjusted  gross income  below a  specified level. For
these purposes, a taxpayer will generally be deemed to be an active  participant
in  an employer-sponsored retirement  plan if for  any part of  the taxable year
either the  employee or  his or  her spouse  is an  active participant  under  a
qualified  pension plan,  a qualified profit  sharing or money  purchase plan, a
403(b) annuity program, a Simplified Employee Pension plan, or a government plan
(other than a plan maintained for state and local employees under section 457 of
the Internal Revenue  Code). Married  taxpayers filing  a joint  return who  are
active  participants in an employer-sponsored plan may make a tax-deductible IRA
contribution of up to  $4,000 ($2,000 for each  spouse) if their adjusted  gross
income  is $40,000  or less.  In order  to receive  the deduction,  the combined
compensation of  both spouses  must be  equal to  or greater  than the  combined
amount.  Between $40,000 and $50,000 of adjusted gross income, the IRA deduction
is  phased  out.  For  single  taxpayers  who  are  active  participants  in  an
employer-sponsored  plan, the  $2,000 deductible  IRA contribution  is similarly
phased out between $25,000 and $35,000  of adjusted gross income. To the  extent
the  IRA deduction is reduced or eliminated by the phase-out rule, an individual
may elect to make nondeductible IRA  contributions that, when combined with  the
deductible  contributions, may not exceed $2,000 ($4,000 for a spousal IRA). The
income on the IRA contribution will not be taxed until withdrawn.
    
 
                                      B-8
<PAGE>
    For a period of seven days after establishment of an IRA Account and receipt
of a disclosure statement,  the investor may revoke  his or her application  and
the  full payment made to  the Account will be  returned. Form 5305-A, available
from the Distributor,  FBL Investment Advisory  Services, Inc., 5400  University
Avenue,  West Des Moines, Iowa 50266, is to be used to establish an Account. The
form should be consulted for detailed information, including circumstances under
which redemption requests must be accompanied  by a declaration of intent as  to
the disposition of the amount distributed.
 
   
SIMPLE RETIREMENT PLANS
    
 
   
    A  SIMPLE retirement plan may  be maintained in any  year by an employer who
has 100 or fewer employees who received at least $5,000 of compensation from the
employer for the preceding  year, provided that the  employer does not  maintain
any  other employer-sponsored retirement plan.  A SIMPLE plan in  the form of an
IRA established for each participant is available through the Fund. For  further
details, contact the Fund.
    
 
TAX-SHELTERED 403(b) PLANS
 
    The  Fund  has  available Tax-Deferred  Plans  under section  403(b)  of the
Internal Revenue Code. Certain tax-exempt  organizations and public schools  may
establish  such plans under which they will  be able to make contributions which
are not currently taxable to their  employees. For further details, contact  the
Fund.
 
CORPORATE PENSION AND PROFIT SHARING PLANS
 
   
    Accounts  for  corporate  pension  and  profit  sharing  plans (IRS-approved
prototypes as well as other plans)  are available. For further details,  contact
the Fund.
    
 
PUBLIC EMPLOYER DEFERRED COMPENSATION PLANS
 
    Employees  of state, county and municipal agencies may make investments with
pre-tax dollars through  eligible deferred compensation  plans authorized  under
section  457  of  the  Internal Revenue  Code.  Contributions  and  earnings are
tax-sheltered until  the funds  are actually  paid to  the employee.  Plans  and
Administrative  Services are available to states, counties and municipalities to
provide a tax-sheltered program for employees. For further details, contact  the
Fund.
 
GENERAL
 
   
    Investors  Fiduciary  Trust  Company  of Kansas  City,  Missouri,  serves as
custodian and  provides  the  services  required  for  Keogh  Plans,  Individual
Retirement  Plans, Section 403(b) Plans and corporate pension and profit sharing
plans. An annual maintenance fee, currently  $10, will be collected annually  by
redemption  of shares or  fractions thereof from  each participant's account(s).
FBL Investment Advisory Services, Inc. performs  plan services for a portion  of
the  fee and during  the fiscal year ended  July 31, 1997  received $739 for its
services. Unusual  administrative  responsibilities  will  be  subject  to  such
additional  charges as will reasonably compensate  the custodian for the service
involved.
    
 
    Since a retirement investment program involves a commitment covering  future
years,  it is important that the investor  consider his or her needs and whether
the investment objective of the Fund as described in the Prospectus is likely to
fulfill them. Premature  termination or curtailment  of the plan  may result  in
adverse  tax consequences.  Consultation with an  attorney or  other tax adviser
regarding these plans  is recommended. For  further information regarding  these
plans, contact the Fund.
 
                                  REDEMPTIONS
 
    The Fund may suspend the right of redemption or postpone the date of payment
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
 
                                      B-9
<PAGE>
holiday  closings); (b) an emergency exists, as determined by the Securities and
Exchange Commission, as a result of which (i) disposal by the Fund of securities
owned by it  is not  reasonable or  practicable, or  (ii) it  is not  reasonably
practicable for the Fund to determine fairly the value of its net assets; or (c)
the  Securities and Exchange Commission by order permits such suspension for the
protection of the Fund's investors. 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 by  FBL  Investment Advisory  Services,  Inc., 5400
University Avenue,  West  Des Moines,  Iowa  50266, prior  to  the day  of  such
determination of net asset value.
 
                               INVESTMENT ADVISER
 
   
    The  following  information supplements  the  information set  forth  in the
Prospectus under the caption "MANAGEMENT OF THE FUND." Pursuant to an Investment
Advisory  and  Management  Services  Agreement  dated  February  23,  1981  (the
"Agreement"),  FBL Investment Advisory Services, Inc. ("FBL" or "Adviser"), acts
as the Fund's investment adviser and  manager subject to the supervision of  the
Fund's  Board of  Directors. FBL  has served  as investment  adviser and manager
since the  Fund commenced  operations  in March,  1981.  FBL is  a  wholly-owned
subsidiary  of FBL Financial Services, Inc.,  which is a wholly-owned subsidiary
of FBL Financial  Group, Inc.,  an Iowa  corporation, 66%  of whose  outstanding
voting  shares  are  in turn  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 Series Fund, Inc. and
FBL Variable  Insurance  Series  Fund.  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 issuers directly, 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 handles the investment and reinvestment of
the Fund's assets and  provides for the Fund,  at the Adviser's expense,  office
space   and  facilities,  simple  business  equipment,  advisory,  research  and
statistical facilities, clerical services and  personnel as may be necessary  to
administer  the business  affairs of  the Fund. The  Adviser also  has agreed to
arrange for  any  of its  officers  and directors  to  serve without  salary  as
directors, officers or agents of the Fund if duly elected to such positions.
 
   
    As  compensation for the investment advisory and management services and the
aforementioned facilities  and administrative  services to  be provided  by  the
Adviser, the Fund has agreed to pay the Adviser an annual management fee of .25%
of  the average  daily net  assets, accrued daily  and payable  monthly. For the
fiscal years ended July 31, 1997,  1996 and 1995 the Fund's investment  advisory
and management fee expense was $81,111, $118,225 and $96,398, respectively.
    
 
   
    The  Adviser is not required  to pay expenses of the  Fund other than as set
forth above. The Fund  pays such other expenses,  which include net asset  value
calculations;   portfolio  transaction  costs;  interest  on  Fund  obligations;
miscellaneous reports;  membership dues;  all expenses  of registration  of  its
shares  under federal and  state securities laws;  all expenses of Shareholders'
and Directors' meetings and of preparing, printing and mailing proxy statements,
reports and  notices to  shareholders;  investor services  (including  allocable
telephone  and personnel expenses  incurred by the Adviser);  all taxes and fees
payable to  federal,  state or  other  governmental authorities;  the  fees  and
expenses  of  independent  auditors,  legal  counsel,  custodian,  transfer  and
dividend disbursing agent and any fees of Directors who are not affiliated  with
the  Adviser; insurance  premiums for  fidelity bond  and other  coverage of the
Fund's operations.
    
 
    The  Agreement  continues  in  effect  from  year-to-year  as  long  as  its
continuation  is  approved  annually  by  vote  of  a  majority  of  the  Fund's
outstanding shares or by its Board  of Directors, including, in either event,  a
majority of those directors who are not parties to such agreement or "interested
persons"  (as such term is defined in the Investment Company Act of 1940) of any
such party except in their capacity
 
                                      B-10
<PAGE>
as directors of the Fund. It may be terminated without penalty at any time  upon
60  days' notice by the Adviser,  or by the Fund by  vote of the Fund's Board of
Directors, or by  a majority  vote of the  Fund's outstanding  shares and  would
terminate  automatically upon assignment. The Agreement may be amended only with
the approval of a majority of the outstanding voting securities of the Fund.
 
    The Agreement provides  that the Adviser  shall not be  liable for 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 loss  resulting from  bad
faith, gross negligence or willful misfeasance of the Adviser.
 
    PORTFOLIO  TRANSACTIONS:   Purchases and  sales of  portfolio securities are
normally principal  transactions. Portfolio  securities are  normally  purchased
directly  from  the  issuer or  from  an  underwriter or  market  maker  for the
securities. There are usually no brokerage commissions paid by the Fund for such
purchases and none were paid during the last three fiscal years. Purchases  from
underwriters  will include a commission or concession  paid by the issuer to the
underwriter, and purchases  from dealers  serving as market  makers include  the
spread  between  the bid  and  asked prices.  The  primary consideration  in the
allocation of transactions is the most favorable price and execution of orders.
 
    Subject to this primary  consideration, while there  is no understanding  or
arrangement to do so, FBL may place the Fund's portfolio transactions with firms
that  furnish research, statistical and  other services. FBL regards information
which is customarily available  only in return for  brokerage as among the  many
elements  to be considered in  determining placement of securities transactions.
No specific value can be determined  for most such information and services  and
they  are deemed  supplemental to  FBL's own efforts  in the  performance of its
duties under the  investment advisory agreement.  Any research benefits  derived
are available for all clients of FBL.
 
    The  investment decisions for the Fund  are reached independently from those
for the other mutual  funds and other clients  whose investments are managed  by
FBL. Such other clients may also make investments in money market instruments at
the  same time as the Fund.  When both the Fund and  one or more of such clients
have amounts available  for investment  in money  market instruments,  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 Directors that  the
benefits available because of FBL's organization outweigh any disadvantages that
may  arise from exposure to simultaneous  transactions. Purchase and sale orders
for the Fund may be combined with those  of other clients of the Adviser in  the
interest of the most favorable net results to the Fund.
 
    Messrs.  Morain,  Gibson, Hoffman,  Marker, Noyce,  Oddy, Warming  and Mses.
Cornick, Rojohn and Followwill, directors and/or officers of the Fund, are  also
directors  and/or officers of FBL as indicated under "MANAGEMENT OF THE FUND" in
the Prospectus.
 
                         UNDERWRITING AND DISTRIBUTION
 
    Pursuant  to  an  underwriting  agreement  dated  December  31,  1983,   FBL
Investment  Advisory  Services,  Inc. (the  "Distributor")  serves  as principal
underwriter and sole distributor of the  Fund's shares, acting as the  exclusive
agent  of the Fund in the  sale of its shares to  securities dealers who in turn
sell the  shares to  the public.  The Distributor  has agreed  to use  its  best
efforts to distribute shares of the Fund. The Distributor pays expenses incident
to  the  sale  and  distribution  of  Fund  shares,  including  preparation  and
distribution of literature relating to the Fund and its investment  performance,
and circulation of advertising and public relations material.
 
    The terms of termination and assignment under the underwriting agreement are
the   same  as  those  under  the  investment  advisory  agreement  except  that
termination for  reasons other  than assignment  of the  agreement requires  six
months' notice.
 
    The  Fund  bears  the  expenses  of  registration  of  its  shares  with the
Securities and Exchange Commission  and the cost  of qualifying and  maintaining
the  qualification of  the Fund's  shares under  securities laws  of the various
states. The Fund also pays expenses incident to the issuance of its shares, such
as taxes and transfer and dividend disbursing fees.

ITEM 27. INDEMNIFICATION
 
    The Maryland Code, Corporations and Associations, Section 2-418 provides for
indemnification of directors, officers, employees and agents. Article IX of  the
Registrant's  Articles of  Incorporation restricts  indemnification for officers
and directors in cases  of willful misfeasance, bad  faith, gross negligence  or
reckless  disregard of the duties involved in the conduct of his office. Article
XV of the Registrant's By-Laws  also provides for indemnification under  certain
circumstances.
 
    The  Investment  Advisory  and  Management  Services  Agreement  between the
Registrant and 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
directors and officers are named insureds.
 
    Insofar as indemnification for liabilities arising under the Securities  Act
of  1933 ("Act") may be permitted to directors, 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 director, officer or controlling person of the  Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,

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 will be governed by the final adjudication of
such issue.

                                                                      EXHIBIT 16


                      EXHIBIT OF PERFORMANCE CALCULATIONS
   This exhibit reflects the calculation of certain performance figures that
  appear under "Performance Information" in the Part B Statement of Additional
       Information ("Part B") of FBL Money Market Fund, Inc. (the "Fund")


A.  YIELD.
1.  FORMULA.  The Fund's current yield quotation is based on a seven-day period
and is computed as follows.  The first calculation is net investment income per
share; which is accrued interest on portfolio securities, plus or minus
amortized discount or premium, less accrued expenses.  This number is then
divided by the price per share (expected to remain constant at $1.00) at the
beginning of the period ("base period return").  The result is then multiplied
by 365 and divided by 7 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 Fund'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:
                        365/7
(base period return + 1)     - 1.

2.  PERFORMANCE REFLECTED.  The representative yield calculations reflected in
this Section A are for the Fund's seven-day period ended July 29, 1988.

3.  CALCULATION OF YIELD.  First, net investment income per share for the last
day of the seven-day period is calculated.  The following figures are provided
for this purpose:

a.  Accrued interest, including amortization of premium and discount, for 
July 29, 1988 equals $5,149.58.

b.  Accrued expenses for July 29, 1988 equal $552.93.

c.  The number of outstanding shares of record for dividend purposes on 
July 29, 1988 equals 23,510,501.690.

Net investment income per share for July 29, 1988 is then calculated as follows:

Net Investment Income Per Share =           Accrued Interest - Accrued Expense
                                            ----------------------------------
                                                    Record Date Shares

              ($5,149.58 - $552.93)/23,510,501.690 = $.000195515/Share


<PAGE>

Net investment income for the other six days in the seven-day period is then
calculated in the same manner.  The resulting figures for each of the seven days
in the period are added together to obtain the net investment income per share
for the period as follows:

         July 29, 1988 . . . . . . . . . . .     $.000195515/Share
         July 28, 1988 . . . . . . . . . . .      .000187563
         July 27, 1988 . . . . . . . . . . .      .000188162
         July 26, 1988 . . . . . . . . . . .      .000176093
         July 25, 1988 . . . . . . . . . . .      .000188110
         July 24, 1988 . . . . . . . . . . .      .000188110
         July 23, 1988 . . . . . . . . . . .      .000188109
                                                  ----------
         TOTAL . . . . . . . . . . . . . . .     $.001311662

Then, base period return is calculated.


Base Period Return =              Net Investment Income Per Share
                                  -------------------------------
                                         Price Per Share

($.001311662/Share)/($1.00/Share) = .001311662

Then, yield is calculated.

Yield = Base Period Return X 365/7 = (.001311662 x 365)/7 = .0684

The decimal return is converted to a percentage by multiplying by 100.

 .0684 X 100 = 6.84%

4.  CALCULATION OF EFFECTIVE YIELD.  The base period return for use in the
formula for effective yield is the same as calculated in Sub-section 3 above.

                                             365/7
Effective Yield    = (Base Period Return + 1)     - 1
                                     365/7
                   = (.001311662 + 1)     - 1
                                  365/7
                   = (1.001311662)     - 1
                   = 1.07074 - 1
                   = .07074

The decimal return is converted to a percentage by multiplying by 100.

 .0707 X 100 = 7.07%
